About O)

The invention relates to elements of hoisting and transporting and robotized systems designed to separate and subsequently transfer flat soft parts of y-type fabrics, leather, etc., and can be used in the sewing and footwear industry.

The purpose of the invention is to increase the reliability of the device.

Figure 1 shows the device, side view; figure 2 - 5 - phase of the device. ,

The device includes a column 1 with a rod of a power cylinder 2 connected with vertical and horizontal drives (not shown) (the body 3 is attached to the gripping elements 4 mounted on the axles 5. The gripping elements 4 are made in the form of telescopic rods, one of which 6 is spring-loaded spring 7. On the sliders, holders 8 are fixed, in which plate 9 is installed with needles 10 and elastic tip 11 with holes 12. In groove 13 of the gripping element 4 with a screw 14 and plate 15 are adjustable transition pore gripping elements through the dead center position 16, and at the other end of the gripping member 4 is fixed abutment screw 17 adjusting the angle of inclination 18.

The device works in the following way.

When the column 1 with the housing 3 is started up, the needles 10 enter into a separate part 19 completely without piercing it (Fig. 2a) | thereafter, elastic tips 11 are brought into contact with the part 19, and as the body 3 is further lowered, moving against each other, forming a fold on the part 19 and clamping it between themselves (Fig. 2b). Upon further lowering of the housing 3, the stops for adjusting the transition of the gripping elements through the dead position 16 (when) come in contact with the pack 20 and the tips 11 with the clamped part 19 from the packet 20 of the fig 2b are lifted) When the gripping elements A move to the dead position, the springs 7 are compressed, after passage of this position, the springs 7 begin to unclamp and force the clamps 4 to rise in

the upper position against the stop of the elastic tips 11 with the clamped part 19 the rod of the power cylinder 2 (FIG. 2 g). The slits 12 in the elastic tips 11 are needed so that the needles 10 of one elastic tip 11 can pass into the slits of the other elastic tip 11 without damaging it. The shape of elastic tips may vary depending on the properties of the part to be separated.

The workpiece is reset using the rod of the power cylinder 2, which, moving down, transfers the tips 11 with part 19 through the dead position and compresses the springs 7, which, further uncoupling, cause the gripping elements 4 to be lowered to the lower position ( their tilt angle

18 does not fit into the housing 3) | thereby releasing the part 19. In this case, the parts 19 can be folded into a new pack on the surface of a table or are dropped in an arbitrary manner, for example, onto a conveyor belt (not shown). Release part

19 it is also possible by simply removing it from the device, and the device moves to its original position.

Depending on the type and thickness of the parts to be separated, by bending the stops for adjusting the angle of inclination of the gripping elements 18, the distance between the end points 11 to the initial position of the device can be changed and thereby adjust the amount of fold on the part 19 to be cut.

The effect of using the invention is to increase the reliability of separation and subsequent transfer of parts, and is achieved due to the fact that the gripping elements are made telescopically with integrated springs, equipped with adjustable dead-end stops (the detachable part is first clamped between the tips and only after that from a pair of checks) and are finally equipped with nicknames with slots and needles, which, first, are not completely punctured into the detachable part, and then t with t entrance part elastic lugs, which together with the needles by sliding Referring against each other to form a crease on the workpiece and clamp it between them, and

they are provided with stops for adjusting the angle of their inclination, which makes it possible to regulate the value of the fold on the part to be detached, depending on its thickness, hairiness and other properties.

Claims (2)

1. A device for separating a part from a pack, which contains two gripping elements with needles at the ends that can be rotated mounted in a drive case, and a rotational drive thereof having a ram cylinder located between the gripping elements, characterized in that the purpose of increasing the reliability of operation, each gripping element is made in the form of a hinged pin 18 fS f3 the body of a spring-loaded telescopic rod with elastic tips at the end, having a slot for moving the needle of the opposite rod, and the drive for turning the gripping elements additionally have a pair of stops for moving the rods through the dead position, each of which is located on the corresponding rod from the working surface. 2. The device according to claim 1, wherein the gripping elements are installed with the possibility of adjusting their initial position. 3, the device non.l, characterized in that the stops for the transition of the rods through the dead position are installed with the possibility of adjusting their position. . 2 ± .
