The invention relates to vending machines.

The level of technology

The closest technical solution is a vending machine for packaged items (patent EP 0807909 A2, priority 17.05.1997)containing the store to accommodate the Packed items stacked in a pile. Working location of the vending machine is the vertical position (with respect to the gravity vector). The store is formed by a connection in the form of a horizontal row of identical vertically composed of elements attached to the housing wall. The element is made in the form of an oblong plate with a Central part and two opposite curved in one direction edges. Every two neighboring element located opposite each other so that between them there is a channel that can be folded in a stack of objects with a possibility of vertical movement on the specified channel. In the lower part attached to the adjustment device for changing the size of the channel depending on the dimensions of the loaded items. The channel is bounded on opposite sides of the side walls, with the other two opposite sides, orthogonal to the side walls, rear wall and limiter. The function of the side wall serves the Central part of the element, the function of the rear wall is one curved cu is the first element and the portion of the casing wall, the limiter function is the opposite curved edge of the item. The items are loaded in a stack through the top of the store (the sash when it is open) in the channel and under the action of gravity to go down to the bottom of the element. The below items can partially resist the loss adjusting device, however, this is not enough for reliable operation of the vending machine. The design of the vending machine does not have sufficient reliability because it does not provide accurate separation of the object from the stack while holding other items from falling out of the channel.

The disadvantage of the invention is the design complexity of the vending machine for packaged items and low reliability.

The aim of the invention is to simplify the design of the vending machine and increase reliability.

In the description of the direction "down" is made coincident with the direction of the gravity vector, under the vertical refers to the direction parallel to the gravity vector, under the horizontal refers to the direction perpendicular to the gravity vector.

Working location of the vending machine is in the vertical position.

The housing 1 consists of a vertically arranged front 13, a back 6, the left 2 and right walls 8 and attached below the horizontal bottom 20 (in this case the front is considered to be the nearest wall when considering the device from the tray 12). The front 13 and rear 6 wall, and the left 2 and right 8 wall is aspolozhena respectively in pairs in parallel, with the front 13 and rear 6 wall located between the left 2 and right 8 walls perpendicular to them. These walls are connected so as to form a horizontal section of the rectangle. In the front wall 13 has a second window 22 of rectangular shape. In this case, the front 13, a back 6, the left 2 and right 8 and the bottom wall 20 are rectangular in shape, made of sheet metal, connected narashima (e.g., welding).

Inside the housing 1 is vertically installed the first 3, second 9 and third 10 partitions and controls. The first partition wall 3 is located between the right 8 and left 2 walls, in connection with them, parallel to the rear wall 6. The second partition wall 9 is located between the front wall 13 and the first wall 3, in connection with them, parallel to the right 8 wall. The third partition wall 10 is located between the right 8 wall and the second partition wall 9, in connection with them, parallel to the front wall 13. The first 3 and 9 second partition have the same height (hereinafter height - the vertical dimension), the third 10, the partition is made shorter, and above all the edges of these partitions (the first 3, 9 second, third 10) are on the same level.

Figure 1-3 all of these compounds the first 3, 9 second, third 10 partitions with the front 13, the right 8 and left 2 walls in order to simplify the drawings while the Ana conditionally. Actually the first 3, 9 second, third 10 partitions can be attached to the corresponding elements as narashima (for example, welding, gluing), and Rethimno (for example, with the possibility of their moving two located on respective opposite walls or partitions horizontal strips with regular notches on the upper edge). In this case, the first 3, 9 second, third 10 partitions attached to the corresponding elements narashimha.

Controls (figures not shown) can be located in different places inside the case. In this case, the controls are located on the bottom 20 of the housing 1.

The channel 23 is a space bounded by the first 3, 9 second, third 10 partitions and right 8 wall. The channel 23 is oriented vertically. The channel 23 is designed to accommodate items 24 (in this case objects 24 in the form of a rectangular parallelepiped). Accordingly, the dimensions of the channel 23 is selected such that it can be placed vertically and withheld from spilling the stack 26 24 items intended for sale. In the case of the first 3, second 9 and third 10 partitions can travel the dimensions of the channel 23 can be adjusted to fit various size of 24 items.

The composition of the eject mechanism includes a platform 4, in which televital 7, the axis 18, the actuator 19. An ejecting mechanism located inside the housing 1 below the channel 23 under the first 3 and the second 9 partitions.

Platform 4 in this case made in the form of a metallic disk having a working surface 15 and the back surface 17, is made flat and parallel to each other (in this case, the work is considered to be a surface on which to place and move objects 24). The working surface 15 of the platform 4 is made smooth to reduce friction between the object 24 and the working surface 15. Platform 4 is located below the channel 23 in the horizontal plane of the working surface 15 facing the channel 23, i.e. up, and so that the portion of the path 5 of movement of the ejector 7 is out of the channel 23. Platform 4 mounted for rotation its actuator 19 so that the trajectory of the 5 movements of the ejector 7 during the rotation of the platform 4 crossed the projection of the first 3 and the second 9 partitions.

The ejector 7, in this case having the shape of a right circular cylinder attached at one end 25 to the working surface 15 of the outer edge 16 of the platform 4. Such arrangement of the ejector 7 is optimal, because the buoyancy of the object 24 requires a minimum effort. The height of the ejector 7 is selected such as to ensure separation from the stack 26 from the bottom of only one of the subject 24. In d nom case, the ejector 7 is attached to the working surface 15 narashima (for example, welding or bonding). In other cases, you may plug connection (e.g., threaded).

From the back surface 17 located beneath the work surface 15 on the reverse side of the platform 4, the center of the platform 4 is attached to the axle 18, connected to the opposite side to the actuator 19. The actuator 19 is stationary mounted on the bottom 20 of the housing 1. The platform 4 may be driven by the actuator 19 in the rotational movement. In this case, is provided by the rotation of the platform 4 in a clockwise direction (here and hereinafter direction clockwise/anticlockwise determined by the direction of rotation of the imaginary-clockwise around the axis 18 of rotation of the platform 4 when considering the device from the top). The distance between the lower edges of the first 3 and the second 9 partitions and the working surface 15 is selected such that the ejector 7 during the rotation of the platform 4 came and went freely into the channel 23 and came out of him, but the 24 items could not go out of the channel 23 of the first 3 and the second 9 partitions, i.e. the height of the ejector 7 is less than the distance between the lower edges of the first 3 and the second 9 partitions and the working surface 15, and the height of the object 24 is greater than this distance.

Between the lower edge 14 of the third partition 10 and the working surface 15 of the platform 4 is formed of the first window 21. The height of the first window 21 is selected such as to ensure the opportunity in the movement of the subject 24 of the channel 23 of the stack 26 of the subject 24 in the direction of the front wall 13 and drop it in the tray 12.

Advanced vending machine is equipped with a tray 12 on which the objects 24 are removed from the housing 1. The tray 12 is inclined so that a part of him, inside of the housing 1, is located above the part outside of the housing 1. Part of the tray 12 inside the housing 1, are summed up under the platform 4 from the back surface 17. The tray 12 is removed from the housing 1 through the second window 22 and attached to the front wall 13. The tilt of the tray 12 is selected such as to provide the offset of the object 24 to the tray 12 down under the action of gravity. In this case, the tray 12 is made of sheet metal, has a rectangular shape, provided with vertical flanges 11 to prevent loss of items 24 to the side.

The operation of the device, illustrating the case of inventions

The device operates as follows (hereinafter referred to as example illustrates the operation of the vending machine).

In the case when the first 3, 9 second, third 10 partitions are made with the ability to change the position, they are pre-placed and fixed so that the dimensions of the channel 23 corresponded to the dimensions of the 24 items intended for sale.

Then the device is mounted in a vertical position in its intended location (e.g., inside the machine for sale cigarette packs). Are you mu is necessary connections (for example, the actuator 19 is connected to a power source and control elements; figures not shown). Vending machine is in the initial operating position in which the ejector 7 is located outside the projection of the channel 23. Items 24 are loaded into the channel 23 on top of the vertical stack 26. Because the size of the channel 23 is installed in accordance with the size of the objects 24, the stack 26 is prevented from spilling sideways first 3, 9 second, third 10 partitions and right 8 wall. The lower the object 24 from the stack 26 from the bottom rests on the working surface 15. Vending machine is ready for operation.

To retrieve the object 24 from the vending machine on a signal from the control elements is driven by a drive 19, from him rotational movement is transmitted through the axis 18 of the platform 4. During the rotation of the platform 4 (in this case clockwise) the ejector 7 is shifted in the direction of the channel 23 is fully inserted in the end face 25 of the lower subject 24 (figure 4), and in this period of time the stack 26 of the subject 24 is held in the channel 23, resting on the third 10 the partition and simultaneously creeped along the working surface 15 (because of the friction force between the object 24 and the working surface 15 small).

In order to facilitate understanding of the drawings figs.4-7 made the following simplifications: only shows two items 24 from the stack 26 to the bottom and above no is, the subject 24 is shown with a gap between them (real objects 24 in the stack 26 are flush with each other), the ejector 7 and the end face 25 of the object 24 is shown with a gap between them (actually they touch each other).

Upon further rotation of the platform 4 of the lower object 24 being pushed to the end face 25 of the ejector 7, is shifted in the direction of the first window 21 (figure 5). Item 24, which is located directly above the bottom item 24, is still partially rely on it, with all the stack 26 of the subject 24 is held in the same position. The rotation of the platform 4 is continued, the lower the subject 24 under the action of the ejector 7 is pulled out in the first window 21, the area of its contact with the working surface 15 and above the subject 24 is reduced. The lower the object 24 is pulled out from under above item and a whole stack 26 of the subject 24, passes in the first window 21 and moves the second window 22, at this time, the ejector 7 is closer to 9 second partition. When the lower part of the object at the weight, more parts in contact with the working surface 15, the bottom item 24 under the action of gravity is separated from the stack 26 and falls into the tray 12 (6). At this time, the ejector 7 is the next item 24, slightly deflecting it from its horizontal position, but this shift does not lead to rasip is in the stack 26, held the first 3, 9 second, third 10 partitions and the right wall 8.

The bottom item 24, once in the tray 12, pulls it down and thus discharged from the housing 1. Simultaneously, the platform 4 continues to rotate as long as the ejector 7 is not completely beyond the projection of the channel 23. The next item 24 from the stack 26, caught the bottom completely falls on the working surface 15 (7) and, thus, the stack 26 is again vertically, platform 4 moves from under the stack 26, not moving it. When the platform 4 will make a complete revolution, the ejector 7 is returned to its original position and is located in the vicinity of the end face 25 of the lower object in the stack 26. On a signal from the control elements, the actuator 19 is turned off, the platform 4 stops rotating. Vending machine stops until the next power-on signal from the control elements.

The bottom item 24, once in the tray 12, pulls it down and thus discharged from the housing 1. Simultaneously, the platform 4 continues to rotate as long as the ejector 7 is not completely beyond the projection of the channel 23. The next item 24 from the stack 26, caught the bottom completely falls on the working surface 15 (7) and, thus, the stack 26 is again vertically, platform 4 moves from under the stack 26, not moving it. When the platform 4 will make a complete revolution, the ejector 7 is returned to its original position and is located in the vicinity of the end face 25 of the lower object in the stack 26. On a signal from the control elements, the actuator 19 is turned off, the platform 4 stops rotating. Vending machine stops until the next Wake-on-si is Nala from the control elements.
