(57) Abstract:The invention relates to the mechanization of auxiliary operations auxiliary equipment sortpriority shops and allows to mechanize disassembly packages shaped profile when you get a certain spatial orientation separated from the package for subsequent operations products. The inventive process of disassembly of the package is reduced to the manipulation of trucks 13 through the chain drive and hydraulic drives. While the fingers 33 remove the bottom product from under the top, which make the trolleys 13 horizontal stroke, lying on the package of the product face, approaching them from above. When this operation is blasting from above is preferable to eject from the bottom. The slits between the fingers used in the casting-off products and the need for lifting of one product over another with the purpose of their trip shaped elements. Separated from the package and tankowanie article 36 precalculates finger on the roller conveyor 2. 3 Il. The invention relates to the mechanization of auxiliary operations auxiliary equipment section rolling shop, as well as thermal and other units of the processing bar products.the square billet.The device consist of racks horizontal or inclined, and provided with a finger chain slippery. The cake square billet using your fingers down to the edge of the shelf, where on an inclined plane at the workpiece slips to the receiving device of the machine (or another unit), thereby breaking away from the rest of the blanks of cake, and slipper stops the movement of the crust of the rest of the blanks prior to the release of a receiving device of the machine from the previous workpiece.A disadvantage of the known devices is that they are not adapted for manipulation by disassembling packets long shaped profiles, which are characterized by the fact that the service profiles can be linked to each other about their shaped elements and the separating device in the form of gravity slid their mutual separation will not provide.Known boot device at the furnace inlet conveyor section mill, in which a floating rack-and-pinion mechanism along the working surface of the rack manipulative fingers with their rotation in planes oriented along the direction of movement of the fingers and the normal to the working surface of the rack. This allows you to move PAL is concerned, and the upper inclined portion of the finger. This cake square billets are placed on the rack crane equipment.However, the known device also does not provide disassembly packages shaped sections.Another disadvantage of the known device lies in the inability to raise one preparation over another so that they are shaped elements have restabilise between them.The disadvantage of this device is the inability to scantouch harvesting any complex shape 180aboutin one operation (for example, there is provided a casting-off slabs).However, the technical essence and the achieved result the device closest to the proposed and therefore taken as a prototype.The purpose of the invention is the provision of mechanized dismantling packages shaped profile when you get a certain spatial orientation separated from the package for subsequent operations products.This is achieved by the fact that in the known device for opening packages of long products, including rack and manipulating the fingers are provided with mechanisms they move along the work surface with the whose the surface of the rack, manipulating the fingers are equipped with the mechanisms of translational movement in a direction normal to the working surface of the rack, made mostly in the form of hollow rods installed in the roller guides, actuators inside, and the mechanisms of rotation of the fingers mounted on the rods and also mainly in their cavities, and the fingers are made in the form of plugs with prongs of different lengths, the outer surfaces of extreme teeth made pointed protrusions hooks.Comparative analysis of the prototype allows us to conclude that the proposed device is characterized in that the manipulating fingers are equipped with the mechanisms of translational movement in a direction normal to the working surface of the rack, made mostly in the form of hollow rods installed in the roller guides, actuators inside the rods, and the mechanisms of rotation of the fingers mounted on the rods and also mainly in their cavities, and the fingers are made in the form of plugs with prongs of different lengths, the outer surfaces of extreme teeth made pointed protrusions hooks.Thus, the proposed device for disassembly of packets long items matched the offer the following properties: the ability to extract using tabs-hooking from a package of a certain product, including push them off the top, shifting into the slots between the teeth of the shaped elements of the profile of the individual pieces, to raise a certain product over the other, and rotate them as on the surface of the rack, and above it, giving separated from the package the products a certain spatial orientation, required to run over them subsequent technological operations, such as editing, knock separated from the package into separate pieces from the rack on zavedenii devices, such as roller conveyors.Due to the fact that the known device for opening packages of long shaped products these properties do not hold, we must assume that these new properties, their presence at the proposed facility is located in a causal connection with its new distinctive features, which allows to make a conclusion about conformity of the invention, the criterion of "substantial differences".In Fig. 1 shows a plan of the device in combination with technological equipment roller-straightener and the supply roller; Fig. 2 section a-a in Fig. 1; Fig. 3 cross-section B-B in Fig. 1.The device comprises a stationary rack 1, adjacent to the roller feed roller 2-ol is connected grating 4. Grating 4 consists of a curved rack beams 5, is provided by the rack 1 swing bearings 6 and in the middle part supported by its rollers 7 eccentrics 8, mounted on the transmission shaft 9 with a drive of rotation 10.Identifier package consists of three movable along the rack 1 along the guide rails 11 on the rollers 12 common chain drive trucks 13. Common chain drive consists of a chain of circuits 14 two on each carriage 13, the transmission 15 and the driven sprocket 16 with a drive of rotation 17 and idler sprockets 18. The upper branch of the chain loops 14 are closed on trucks 13. The main trolley 13 is located below the rack extending in the vertical direction of the metal structure which includes spaced vertical support rollers 19 that secures with a possibility of vertical movement of the hollow rod 20. In the cavity of the rod 20 one after another has two piston cylinder. The housing 21 of the lower cylinder below using spatial swivel 22 is fixed on a metal trolley 13 and in the upper part of the lower cylinder using a similar swivel 23 connected to the upper end of the piston rod of the hydraulic cylinder (position, on the one installed from the bottom of the rod 24 downward, and housing 25 up. His rod 24 also using spatial swivel 26 is connected to the rod 20 and to the housing 25 from the top secures the toothed rack 27.On top of the rod 20 is fixed to the casing 28 made integral with the shaft rack and pinion gear 29. Gear shaft 29 is in constant engagement with the rail 27. On the speakers on both sides of the body 28 of the cylindrical ends of the shaft-gear 29 is wearing two curved finger 30 with rotating together with the rotation shaft of the gear 29.Curly finger 30 is made in the form of a fork with prongs 31, 32 and 33 of different lengths, spaced apart at different distances. With the opposite teeth of the hand, the finger 30 has a slot 34. On the outer surfaces of teeth 31 and 33 made pointed tabs-the tabs 35.The object of interaction with the finger 30 in this example are bulb flats profiles.Required orientation bulb flat profile for the task, roller straightening machine is marked POS. 36.Supply to the cylinders of the working fluid under pressure in this design truck 13 made from the installed hydropower station 37.Due to the fact that the lower branches of the chain loops 14 are fed through the con is be sagging, clinging to the construction of the trolley and create an emergency situation, the steel trolley 13 is equipped with two smooth rails 38, on which the lower branches of the chain loops through the design of the truck, and this does not create a hazard clutch with her.The device operates as follows.Crane workshop (shown only hook 39 of the crane) package 40 profile stack for receiving and tilting the grating 4. Briefly turning on the actuator 10 via the transmission shaft 9 eccentrics 8 are rotated by a small angle and thus cant racking beams 5. Devoid sling pack 40 is partially scattered, and part of the profile gets to the rack 1. The scattered part of the package when it is in a chaotic state: profiles can be oriented in a random sample, some of them can be interconnected, and some skewed.The parser performs packet, as indicated, consisting of three trolleys 13, manipulated by using two adjacent trolleys shorter products, and use extreme trucks longer. In this work two simultaneously used trucks 13 can be synchronized, and may be unsynchronized, for example the m If you need to raise the fingers 30 working fluid from the hydraulic station 37 is fed under pressure into the cavity under the piston of the lower cylinder. His rod extends from the housing 21 and the hinge connection 23 of the post 20 raises the latter to any set by the operator move. Hydroscheme constructed in such a way that in any given position of the rod 20 is inserted from an arbitrary vertical displacement (in the technique of hydraulic actuator such technical solutions are known). If necessary, lower the rod 20 with the fingers 30, the working fluid is fed under pressure into the cavity above the piston of the lower cylinder. The rod retracts into the housing 21.During the rotation of the fingers 30 in a clockwise direction, the working fluid is fed under pressure into the cavity above the piston in the upper cylinder. This hinge connection 26 of the stem 24 of the post 20 of the housing 25 of the upper cylinder starts to move upward relative to the rod 20 together with rigidly attached to the rail 27. The rail 27 through constant gear mesh with the shaft gear 29 rotates the latter in a clockwise direction, and with it, and planted it to the ends of the fingers 30.If necessary, rotation of the fingers 30 in subcorpus 25 is lowered relative to the rod 24 and the rod 20, and rake 27 rotates the pinion shaft 29 in a counterclockwise direction.When you want to exclude from the operation of any of the trolleys 13, the rod 20 lead to the lowest position, and the fingers 30 also come in one of two extreme positions. When it moved synchronously with other trucks 13 chain drive this truck 13 passes below the rack 1 beneath it products and does not touch them.The process of dismantling the package using the proposed device is reduced to the manipulation of trucks 13 through the chain drive and hydraulic drives. This hooks 35 remove the bottom product from under the top, which hooks 35 is conducted to the package 40 from the bottom and make the trolleys 13 horizontal stroke, lying on the top of the package of the product face, approaching them from above, for example, using a hook 35, located on the elongated prong 33. When this operation is blasting from above is preferable to eject from the bottom. The slot 34 and the slots between the teeth 31, 32, 33 are used in the casting-off products and the need for lifting of one product over another with the purpose of their trip shaped elements. In all of these operations as possible synchronized operation of the package and skanowanie product 36 is pushed onto the roller table 2 for the task in machine 3.Thus, the proposed device allows to eliminate heavy manual labor for disassembly packages shaped profiles. In addition, the device provides a desired orientation separated from the package of products and their delivery on technological axis of the equipment, performing subsequent processing of hire.
