The invention relates to mechanical engineering, in particular, to devices allowing the mechanization of the process of single-piece feeding of blanks from a package.

A device for disassembling a package of products is known, which comprises a rack mounted on a support, fixed on it a rotary assembly with a plate with load-gripping elements fixed on it from a drive in a vertical plane. ij.

A disadvantage of the known device is that in order to move the products from the stack to any position of the technological process it is necessary to perform several manipulations associated with inconveniences in maintaining the device.

The purpose of the invention is the improvement of serviceability.

To achieve the goal, in the device for parsing a product package containing a rack mounted on a support, a lever fixed on it from a drive in a vertical plane with a plate fixed on it with load gripping elements, the plate is fixed to move from a drive in a vertical plane, load gripping elements are mounted on a plate with the possibility of vertical movement by means of rods of different lengths, increasing in the direction of the increment of products, freely located in the holes made in the plate , And the device is provided with two pivoting the actuator in a plane inclined gorizongpnoy eg l yuschimi mounted on the stand relative to the direction ke symmetrically vschachi products. I

FIG. 1 shows a general view of the device; in fig. 2 is a view A of FIG. one.

The device for parsing the product package contains a support 1, a rack 2,. on which lever 3 is pivotally fixed, one end of which is pivotally connected to power cylinder 4, pivotally mounted on rack 2. At the other end of lever 3 rolling pins 5 are movably mounted, on which plate 6 is rigidly fixed, which is fixed to lever 3. One of the skalok 5 has a protrusion 8. On the plate 6 on the movable rods 9 are load-gripping elements - electromagnets 10, and the movable rods 9 are arranged in pairs. Movable rod 9 of the same pair have the same length. The length of the movable rod 9 with the transition from one pair to another increases by the same value. On the rack 2 is the limit switch 1). Limit switches 12 and 13 are located on lever 3. Limit switch 14 is located on plate 6. Axes 15, mounted on support 1, have curved inclined guides 16 pivotally fixed, with two sides directing them, forming an acute angle. The inclined guides 16 are hingedly connected to the power cylinders 17, which are hinged on the rack 2. The inclined guides 16 form an inclined angle. An end switch 18 is fixed to one of the axes 15. The stops 19, mounted on the support 1, form a bunker for installation of a package of products. On the support 1 on the telescopic rods 20 is a spring-loaded receiving tray 21, under which is fixed the limit switch 22.

A device for disassembling a package of products operates as follows. I

In the initial position in the bunker formed by the stops 19, mounted on the support 1, set the package of products, such as channels. Then the power cylinder 4 rotates the lever 3, hinged on the rack 2, in a position in which the plate 6 is above the package with channels. In this case, the lever 3 presses the limit switch 11 and the power cylinder 7, receiving a signal from it, begins to lower plate 6. The plate 6 is lowered until all electromagnets 10 mounted on moving rods 9 reach the channels in the package, and The location of the electromagnets is such that two electromagnets 10 interact with each channel regardless of its location in the package. At the same time, the limit switch 14 triggers, which gives the signal to the actuator 7 to lift plate 6. Ppita 6 lifts and carries One row of channels from the packet, which are held by electromagnets 10.

When the plate 6 reaches the upper position, the limit switch 13 triggers and gives the signal to the power cylinders 17 to rotate the inclined guides 16. At the same time, all the grippers of the electromagnets 10 of the channel bar are located at the same distance from the inclined guides 16 due to the different length of the movable rods 9, which causes a decrease noise during operation of the device, since the channel in free fall from the electromagnets 10 to the slits passes the minimum distance due to the size of the channels, which should slip between the electromagnets 10 and the inclined guides. Turning, one of the inclined guides 16 presses on the limit switch 18 fixed on the axis 15, which gives a signal to stop the electric current through the rightmost pair of electromagnets 10, as a result of which the latter releases the channel, which, falling on the inclined guides, rolls into the receiving tray 21, located on the telescopic rods 20, the latter presses the limit switch 22. After removing the channel from the receiving tray 21, the springs lift it and the limit switch 22 sends a signal to stop the electric After the next pair of electromagnets 10, and the next channel, falling on the rails, rolls into receiving lotto 21. When all the channels of the row captured by the electromagnets 10 are inserted, limit switch 22 gives a signal to the power cylinders 17 and they turn the rails 16. When This limit switch 18 gives the power cylinder 7 to lower the plate 6 and turn on the electric current through the electromagnets 10. The cycle repeats.

When electromagnets 10 are seized on the last row of channels in flight, the rolling pin 5, having a protrusion 8 at its end, presses the limit switch 12, which rebuilds the signal program of the limit switch 22. After the last channel is removed from the bag from the receiving tray 21, the limit switch 22 gives a signal to the actuator 4 to rotate the lever 3, and to the power cylinders 17 to rotate the curved inclined rails 16. The device occupies the initial position.

The use of the proposed device makes it possible to improve the service conditions, since it has easy access to the place of installation of the package of products or containers with products. In the device, any self-controlled gr-sensitive elements can be used, depending on the material of the products being disassembled, which will expand its technological capabilities.
