The invention relates to mechanical engineering, instrument making, is intended, in particular, for the layout of round blanks such as injection needles and can be used in the medical industry.

The aim of the invention is to improve the reliability of the device by eliminating jamming when feeding the latter into the material handler.

Figure 1 shows a device for arranging round billets, a general view; figure 2 is a view of And figure 1; on fig.Z - section bb in figure 2; on figa - section bb In figure 2; figure 5 is a section of the GG in figure 1, figure 6 is a cross-section dD in figure 1; figure 7 - the arrangement of the mechanisms in the upper position of the bins; on Fig - the same, with the lower position of the bins.

The device contains a loader and drive with the appropriate drives. The loader consists of two bearing elements 1, made in the form of sectors rigidly interconnected by links 2. On each of the elements 1, lodgments 3 and 4 are installed. The bearing elements 1 are hingedly with axis 5 connected with brackets 6 fixed on The base 7. On the base 7, the bracket 8 is also rigidly mounted, on which the hydraulic cylinder 9 is hinged, the rod of which

pivotally connected to one of the carriers 1.

The tray contains a frame 10, on which the guides are installed 11-13. A hydraulic cylinder 14 is mounted on the frame 10. On the guides 12, the stops 15 are fixedly mounted, and the guides 13 are fixed to the stops 16. On the guides 11, the plate 17 is mounted with the possibility of reciprocating motion, on which the hopper 18 is rigidly fixed. the support 19 mounted on the frame 10, the rod of the hydraulic cylinder 14 is connected to the plate 17 by a bracket 20. The hoppers 18 are equipped with shutters 21, which are pivotally connected to the axles 22 with the walls of the hoppers 18, and adjusting mechanisms made in the form of screws 23. On the plate 17 are placed those 24, on which the front walls 25 of the bunkers 18 are mounted for movement, made in the form of a fork, the working surface of which has a gentle bevel. Hinges 26 are hinged on the walls 25 with springs 27 housed therein, which are hingedly connected with brackets 28 rigidly mounted on the plate 17. The frame 10 is fixedly attached to the drive tilt bracket 29 which is hingedly connected to the axis 5 of the rods 30. Adjusting screw 31 is pivotally connected at one end with the bracket 29 and the other with the bracket 32 mounted on the base 7. Into the bunker

18 load the needle and the needle stitch 33.

The device works as follows.

Under the action of hydraulic cylinder 14, plate 17 with bunkers 18 moves upward until walls 25, abutted against stops 15, are buried under the bottom of bins 18. When plate 17 moves, springs 27, enclosed in housings 26, press walls 25 to the rear wall The plates 17, preventing their spontaneous movement down along the guides 24. When meeting with the stops 15, the walls 25 along the guides 24 are shifted back, occupy the posterior wall behind the rear walls of the bunkers and are held in this position by means of the housings 26. At the same time, the needles The blank blanks 33 are placed on the guides 12. C Then, the carrier elements 1 under the direction of the hydraulic cylinder 9, turning on the axis 5, are lowered all the way onto the guides 13, while the outer surfaces of the guides 12 and 13 and the cradle 3 and 4 are in the same plane. After that, the plate 1 7 with bunkers 18 under the action of the hydraulic cylinder 14 begins to move down. At the same time, the needle blanks 33, rolling from the guides 12, fall onto the lodgements 3 and 4 and, westward, one by one into the nests of the lodgments fill them along the entire length. The blanks 33, which did not fall into the nests of the cradle 3 and 4, roll down onto the guides 13. Depending on the diameter of the needle blanks 33, the shutters

21 adjusted by turning around the axis

22 and installing a gap between the end of the flaps and the bottoms of the bunkers 18 with the screw 23 so that, as the 33 needle beds are filled with needle blanks

3 and 4, the number of needle blanks 33 behind the flap 21 has always been constant.

When the extreme lower position is reached, the bunkers 18 of the wall 25 from the contact with the lugs 16 in the directions 24 move forward and because their front part, having a gentle bevel, is located below

17H

Uropn the outer surface of the cradle 3 and 4 and the guides 13, and their rear part rises above them, there is a smooth capture of the blanks 33 remaining on the guides 13.

Then, under the action of the hydraulic cylinder 9, the bearing elements with the needle blanks 33 in the slots of the cradle 3 and 4 are rotated to a horizontal position and the blanks 33 are loaded into cassettes (not shown) for subsequent processing. The bunkers 18 with walls 25, on the working bodies of which there is a part of the blanks 33, begin to move upwards and reach the upper position, after which the bearing elements with the cradles 3 and 4, freed from the blanks 33, return to their original position between the guides 12 and 13, and the cycle repeats.

If it is necessary to lay out blanks of a different diameter, lodgements 3 and 4 will change, having corresponding angles of inclination of the sockets 45-90, the tilt of the pickup mechanism is controlled by a screw 31, and the installation of the shutters 21, as indicated: the number of blanks behind the shutter must always be constant.
