The invention relates to a method and to a device for the manufacture of bulk items, for example, such as models, matrices, forms and other similar articles.

In particular, the present invention can be applied as a method of manufacturing solid objects by bonding with each other a large number of relatively thin layers, the shape of each of which correspond to the contour of a thin slice of the manufactured object. Such methods are especially of great interest at the present time, because they allow you to take advantage of that offer getting a wide development of computer technology computer-aided design (APR), as well as computer technology-aided manufacturing (APR). For example, in the description of the invention to the U.S. patent 5071503 discloses one such technology, according to which each individual layer is a pre-formed sheet that is glued to the partially manufactured object with the application of adhesive to the areas that define a shape of the manufactured house is in circuit, easy then separated.

The purpose of the present invention is to provide a fundamentally new way, as well as devices that would provide for certain advantages in comparison with known technologies and technical means, for example, as disclosed in the description of the invention it is opposed to the above patent.

In accordance with one of the distinguishing features of the present invention features a method of manufacturing a volumetric object, composed of a large number of thin, pre-formed sheet, each of which is glued with its opposite sides to the adjacent neighboring leaves that are on the opposite side of him, each sheet is cut along the contour corresponding to the shape layer provided they are manufactured in the object specified by the sheet, characterized in that one side of each sheet before cutting it to the appropriate path and sticking to adjacent this side of the adjacent plate is covered with a coating of preventing the bonding substance, which never sets on the surface of the sheet, draw a contour line is I of the corresponding sheet and gluing it to the adjacent this side of the adjacent sheet only on the surface of the sheet, which is located within a corresponding contour, is glued to the adjacent to the specified sheet from this side of the adjacent sheet, which allows to separate the glued part of the corresponding sheet outside the specified contour, adjacent to the sheet adjacent the sheet and made a volumetric object.

Thus, taking into account the fact that the process is carried out in accordance with opposed to the above patent, involves the application of adhesive to separately select the surface that is within the path defined by the shape of the corresponding layer of the manufactured product, it should be noted that the present invention is provided to cause preventing the bonding substance on the individually selectable surface, outside, outlined the specified path.

The sheets can be on one surface an adhesive applied to it previously in the form of a coating, or they can each individually be covered with an adhesive applied in the form of a coating on one surface simultaneously with the application of preventing the adhesion of the substance on priznatelna is easier to implement, because it requires precise control over the distribution on the surface of the adhesive, and a completely different substances that prevent bonding, which is much easier can be done due to the different nature of these two substances. In addition, since those parts are preformed sheets, which will not then become a part of the manufactured item (i.e., waste), do not stick together with each other, they can then be removed from the manufactured object.

In accordance with other distinctive signs, characteristic for the considered in the description below of preferred embodiments of the present invention, the sheets are individually served on a horizontal table and placed a foot on the table, which consistently goes down as one after another received these sheets. Each such sheet coated preventing the bonding substance applied in the form of a coating on the upper surface outside the corresponding contour, and its bottom surface coated with an adhesive, the sheet being covered by these substances is due at the time of submitting it to the horizontal is ptx2">

In one of the covered in the description below of preferred embodiments of the present invention, each individual sheet is covered preventing the bonding substance applied in the form of a coating on its upper surface with an appropriate applicator, designed for coating of such substances, the operation of which is carried out in such a way as to prevent the bonding substance applied outside contour of the respective sheet, in the process of moving this sheet. In the second question in the following description of preferred embodiments of the present invention, each sheet is covered preventing the bonding substance applied in the form of a coating on its upper surface with a corresponding moving the applicator intended for the coating of such substances, the operation of which is carried out in such a way as to prevent the bonding substance applied outside contour of the respective sheet at a fixed position of the sheet.

In addition, the present invention provides for the what I considered using technological methods.

Other distinctive features and advantages of the present invention will be apparent from the description.

The invention is illustrated in the following description, which is conducted only on an individual examples of its implementation with reference to the accompanying drawings, in which:

Fig. 1 is a perspective view illustrating one of the embodiments of the device, the design of which is made in accordance with the present invention;

Fig. 2 is a perspective view illustrating the same device, as shown in Fig.1, showing it from the opposite side;

Fig. 3A-3C is a schematic diagram illustrating the process of manufacturing volume of the object in accordance with the method proposed in the present invention, and using the device shown in Fig.1 and 2;

Fig. 4 and 5 - dimensional images similar to those shown respectively in Fig. 1 and 2, but illustrating the second of the considered variants of the device, the design of which is made in accordance with the present invention.

The device shown in Fig. 1 and 2, is used for the manufacture of bulk is muenich sheets 3, bonded to each other, each sheet is cut off at the circuit 4 corresponding to the shape layer, represented in visitors subject. Leaves 3 after their circumcision on respective paths 4 and gluing them to each other indicated by the position 3' in Fig.1 and 2. Waste remaining after removal of this piece is made of a volumetric object 2, indicated by the position 5 in Fig.3.

The device shown in Fig.1 and 2, comprises a frame 10, includes an upper section 10A and lower section 10b. Preformed sheets 3, used in the manufacture of the specified volume of subject 2, should be stacked in a vertical foot on the horizontal base 11 mounted in the lower section 10b of the bed. Each sheet 3 is fed from the top of the foot on the base 11 by means of the feeding rollers 12, 13, 14 in the upper section 10A of frame 10, and is placed on the table 15, on which the layer by layer is the capacity of the produced volume of subject 2.

Table 15 is driven in the vertical direction by means of motor M1and the endless belt 16 is mounted in such a way as to make the rotation of the four screws 17, the mouth of the s holes performed in each of the four corners of the table 15.

In the upper section 10A of frame 10 has a corresponding applicator 20, intended for coating of adhesive, which adhesive is supplied from the tank 21, is applied in an even layer on the bottom side of each sheet 3 at the time of filing it in the upper section 10A of frame 10.

In addition, there is also a second applicator 22 located at the upper end of the frame 10 and is designed for coating of preventing the adhesion of the substance on the upper side of each sheet 3 at the time of filing it in the upper section 10A of the bed, hanging over the table 15. The applicator 22 produces being covered upper surface of each sheet 3 a substance that prevents bonding, and this operation is performed in such a way that prevents the bonding substance blanket an entire upper surface of the sheet except that part of it which is within the circuit 4, determined by the shape of the corresponding layer of the finished volume of subject 2, we present the corresponding list.

In the example illustrated in Fig.1 and 2, the applicator 22, intended for coating and is receiving her ability to move along one of the orthogonal axes (transverse axis) in the process of feeding the sheet along the other orthogonal axis (longitudinal axis), causing the applicator covers the entire upper surface of the sheet. As the applicator 22, intended for coating of preventing the bonding substance may be applied printhead any suitable for this purpose type, for example, such as used in an inkjet printer, rechargeable liquid paint, a printing device drum type, a laser printer, or any other similar device. Using this applicator separately on select areas of the upper surface of each preformed sheet 3 is applied to any material, solid or liquid, which serves as an anti-bonding substance towards the adhesive substance has already been done during preview processing them using the applicator 20 on the lower surface of the sheet, making then stacked on top of the sheet, the next sheet will not stick to the underlying sheet on the surfaces of contact with him, which includes preventing the bonding substance, but at the same time provided will be reliable gluing where preventing the bonding substance is absent.

Deistvie bonding substances by type negative image relative to the circuit 4, determined by the shape of the corresponding layer of the finished volume of subject 2. This means that prevents the bonding substance is applied in such a way that they covered all the surface of the preformed sheet 3, except for those surfaces that are located within the contour of 4, determined by the shape of the corresponding layer of the finished item. Thus, each stacked on top of another sheet 3 will stick to the underneath next sheet 3 only within the contour of layer 4, which is defined by the specified overlay on top of the sheet, and will not stick to the below list outside this contour.

The device illustrated in Fig.1 and 2, further comprises a cutting tool 30, the control operation which is performed so that was produced circumcision unnecessary material sheet along the contour of 4, determined by the shape of the corresponding layer of the finished item 2. The cutting tool 30 is mounted on the cylinder 31 is moved by means of the carriage 32. The carriage 32 is driven in a longitudinal direction relative to the frame 10 by means of the motor M3with an endless belt 34. In addition, the head 30 with the cutting tool performed well and with capability to move in a vertical direction by means of a solenoid 35, mounted on the cylinder 31, advancing in its working position, in which circumcision is located under the head of the sheet 3 or ubinas in non-operating position, in which circumcision does not occur. Requires the presence of the pressure roller 36, which tightly presses the sheet at the time of his circumcision to the previously processed the same leaves, lying on the table 15.

The adhesive applicator 20 is also provided with a solenoid 37 to ensure move the adhesive applicator in the operating or non-operating position. For example, the adhesive applicator is moved to the off position at the time of filing of the first sheet 3, to prevent adhesion of the sheet to the table 15.

Illustrated device additionally includes also a control unit, indicated generally by the position 40 and is designed to control the operation of the motor M1, M2and M3, the applicator 20 for applying adhesive, the applicator 22 for applying preventing schleifenbaum the device in question, acting in the following way.

A lot preformed rectangular sheets 3 to be used in the manufacture of the corresponding volume of subject 2, for example as shown in Fig.3A, should be placed in a vertical stop on the base plate 11 of the device in question, located in the lower section 10b of his bed, and each sheet individually served then in the upper section 10A of this frame in such a way as to take up its position on top of the table 15, on which the layer is a gradual increase of the produced volume of subject 2. In the initial state of the considered devices table 15 occupies its extreme upper position, and as laying each layer formed on the object by giving the layer a corresponding shape moves the table in a vertical downward direction, sequentially carried out with the assistance of the electric motor 1, drive belt 16 and the chassis screws 17 so as to provide the possibility of placing the next, again stacked layer visitors on the subject.

At the time of filing of each ACE in the upper section 10A of frame 10 of the device in question is being covered completely the entire surface of the sheet with its lower side with an adhesive, applied with a glue applicator 20, and its upper side is selectively covered preventing the bonding material that does not stick to the adhesive substance and is applied in the appropriate places using the applicator 22. The adhesive layer caused by the applicator 20, covers the entire bottom surface of the corresponding sheet, while preventing the bonding substance is applied using an applicator 22, covers only the portion of the upper surface of this sheet, which is not within the circuit 4 corresponding to the shape layer that is represented by this leaf in a finished three-dimensional object. For example, if the corresponding layer formed of this sheet in the final bulk product, has a square contour, rectangular sheet 3 that defines this layer will be covered with a protective substance in the part of its surface, which is not included in the square that defines the corresponding layer in the final product, i.e., the surface inside the square is not eligible for preventing the bonding material.

It should be understood that the data on the contours of all of the individual layers in the finished object, which in the process of its manufacture must be obtained from the pre is P) or computer-aided manufacturing (APR), either in the control unit 40 or in a separate storage device to provide access to the control unit to ensure the implementation of appropriate operations control the operation of the applicator 22, intended for coating of preventing the bonding material, and also the cutting tool 30 during the processing of the corresponding sheet 3.

After the appropriate sheet 3 is placed on the top of the foot on the table 15, while being completely covered over its entire bottom surface with an adhesive and selectively covered in the appropriate places on its upper surface preventing the bonding substance applied outside contour that is defined for this worksheet, as described in the action enters the cutting tool 30, which controls the control unit 40, when cutting the sheet along the line circuit 4 that is defined for the corresponding sheet. Ensuring the implementation of this operation, the control unit 40 activates both motor M2and M3drive the cutting tool 30, driving their work in such a manner that movement of the cutting ant the HT 30 in its operating position, which is circumcision, and prints it out.

Thus, layer after layer is gradually increasing volume of subject 2, manufactured on the table 15, and each of these layers represents the appropriate slice of the whole subject in General. When all of these layers will be appropriately placed each in its place, is the bonding of each of these layers adjacent thereto on both sides of the adjacent layers, but only on those areas that do not have coverage from preventing the bonding substance. Therefore, after all the sheets intended for the production of these total volume of subject 2 in General, will be properly trimmed and superimposed on each other, bonding the sheets together between them will occur only at points of contact with each other, their surfaces within circuit 4, a corresponding cross-section in the finished three-dimensional object, making it easy to separate the rest, not kleibsiella of the sheets outside of this path, from the specified volume of the subject. This operation is shown in Fig.3A-3C, which shows C 2, as part of these sheets, not included in the composition bonded to each other surfaces that are limited to the respective paths, indicated by position 5.

In Fig.4 shows the device in many respects similar to those shown in Fig. 1 and 2. To facilitate understanding, the following discussion those parts of the device shown in Fig.4, which are identical with the corresponding parts of the device shown in Fig.1 and 2, are indicated by the same number of items.

The main difference between the device shown in Fig.4, is that the applicator is designed for coating of preventing the adhesion of the substance indicated by the position 22' shown in Fig.4, is mounted on the same cylinder 31' together with the cutting tool 30. Therefore, in the device shown in Fig.4, sheet 3 remains fixed not only at the time of his circumcision on the circuit by means of the cutting tool 30, but also during application on it preventing the bonding of a substance with the help of applicator 22'. Thus, the applicator 22', intended for coating of preventing the bonding substance is also shown in the movement in both longitudinal and transverse e.g. is it bonding substance on the upper surface of the corresponding sheet as described, ongoing with reference to Fig.1 and 2.

Essentially all other respects, the construction and principle of operation of the device shown in Fig. 4 correspond to the above description, ongoing in relation to the device shown in Fig.1 and 2.

The sheets 3 can be made of any acceptable for use for such purpose of a plastic material, for example of polyvinyl chloride, epoxy resin, plastic-based, nylon, etc. They will need to have an appropriate thickness is selected depending on the accuracy you want to get to the finished object made with the help of the device in question. It would be preferable to provide that the sheet 3 has a thickness of about 0.1 mm, which would require approximately 100 of such sheets to produce the corresponding processing each one centimeter height of the produced volume of the subject.

As substances that prevent bonding, can be applied to any acceptable for use with this purpose, a material that does not stick to the applied adhesive substance. As an example, you can specify on the application of wax sastago on the accompanying drawings, provides for the application of adhesive on the lower surface of each sheet during the corresponding processing in the device, it should be understood that the pre-formed sheets can be also pre-coated with an adhesive before will be loaded in this device. In accordance with the design also assumes that the pre-formed sheets may stick together with each other thanks to the use of an appropriate solvent is applied to the bottom surface of the corresponding sheet, resulting in its softening, which contributes to bonding it to underneath the sheet over the entire surface except in those places where the top surface of the corresponding sheet selectively covered was a substance that prevents bonding.

Additionally, it is assumed that it is possible to forego the use of adhesives, providing instead the connection of the sheets to each other under the influence of heat and/or pressure, with the exception of those places on their surfaces, which are selectively covered by a substance that prevents such a connection, and in this case, the applied heat and/or the Oia. The bonding of the sheets between them can be done before it can be applied to a cutting tool for cutting the sheet along the contour, during a circumcision or after him. A substance that prevents bonding, can be podkrucheno in the corresponding color, which is desirable to get made this way, but to put this matter on appropriate surfaces can use any of the known methods, for example by electrostatic method, using a laser, thermal transfer printers, etc. in Addition, the applicator is designed for coating of adhesive may be mounted in such a way as to ensure the ability to move it along one of the axes (e.g., transverse), while the preformed sheet, processed with it, is moved along the other axis.

In addition, a substance that prevents bonding, can be applied directly on top of the glue or before the same side of the sheet is coated with adhesive, and in these cases, the applicator 22, intended for coating of preventing the bonding substances shall Bud is of ity of adhesives. In addition, the sheet can be completely covered over its entire surface with a substance that prevents bonding, and this substance is subsequently removed from that part of the respective sheet to be glued, and in this case, instead of the corresponding applicator, indicated by the position 22 in Fig. 1, must be applied so-called "scraper" site that is designed to remove substances that prevent bonding, with the portion of the respective sheet, where its presence is undesirable in some mechanical way, by application of any chemical substances with the help of a laser, etc. To the same adhesive may be applied to the upper surface of the sheet, and preventing the bonding substance on its lower surface, and not Vice versa, as indicated in the above description.

In an alternative embodiment of the present invention, instead of using an adhesive substance coming from the applicator 20, which is intended for coating of the adhesive, which will ensure the adhesion of the processed thus the sheet to the adjacent neighboring sheet over its entire surface, except uchastvstvuyut applicator 22, you can provide the application with the help of applicator 20 on the same sheet of such adhesives, the characteristics of which will ensure the adhesion of the specified sheet to the adjacent neighboring sheet only in those areas of its surface, which will be appropriate activating substance deposited on them using the applicator 22. In this embodiment of the present invention, the activating substance is applied only to the part of the sheet surface, which is located within the contour of 4, allowing adjacent adjacent sheets will stick only within a bounded by this contour plot, which was caused activating substance.

According to an alternative variant, the device includes a horizontal table, a feeder designed for feeding and laying at the foot of these sheets on said horizontal table, a drive unit designed for a gradual lowering of the mentioned table down as one after the other act mentioned sheets, adhesive applicator for applying adhesive substance having such characteristics that allow it to stick to the sheet only on the surface side of each sheet before circumcision on the appropriate path and bonding with the next adjacent sheet on this side, activating substance covers only the surface of the sheet, which is located inside the contour of the layer represented by this leaf inside this subject, so, after the appropriate sheet is cut and applied to the next adjacent sheet only the surface of the sheet inside the corresponding circuit is attached to the specified next adjacent sheet, allowing the rest of the unbound portion of the respective sheet, which is located outside the path, separated from the next adjacent sheet and on the volume of the object.

Preferably the location of the above-mentioned applicator designed for coating of activating substances, thus, to ensure the application of the aforementioned activating substance on the upper surface of the above-mentioned sheets.
