Description

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - knot of FIG. 1.

The product transfer device comprises a pair of double-arm levers 3 mounted on the frame 1 by turning the HSTe from the electric drive 2, carrying fork arms on the shoulders. The jaws 4 are for the product. One arm of a pair of levers 3 is provided with a counterweight 5, rigidly connected with a fork fork 4 mounted on the axis b, the second shoulder is equipped with a common counterweight 7 mounted on a semi-axis x 8 between the levers 3, with the shaft.9 of the pair of levers, axis 6 and the axles 8 are interconnected with each other and with a kinematic gear drive in the form of gears. wheels 10-13 and their chains 14 and 15, ensuring circular rotation of a pair of levers 3 relative to shaft 9, and forks 4 and common counterweights 7 relative to shaft 9 and their own axes 6 and 8.

The shaft 9 of the pair of levers 3 receives rotation through gears 10 and 11 connected by a circuit 14 from the electric drive 2. The wheels 12 and 13 of the forks 4 and common counterweights 7 are articulated by the chain 15. The forks 4 are provided with lodgements 16 with oblique walls 17. Shaft 9 is mounted on bearings 18 mounted on frame 1, on which electric actuator 2 is also mounted.

Depending on the length of the products being reloaded, an even number of devices for reloading the products are joined between two pairs of devices. a common electric drive 2 is installed.

The device works as follows.

The lodgements 16 in the initial state are at the bottom (Fig. 1 and 2). The counterweights 5 serve to orient the cradle 16 with the pocket upward. To transfer products 19 from technological position 20 to position 21, an automatic control system (not shown) is turned on by electric drive 2. A pair of levers 3 through gears 10, 11 and chain 14 receive a rotational circular motion clockwise from electric drive 2. Lodgments 16 approach Bottom to the product m 19, smoothly remove the product 19 from the technological position 20.

Rotating the far, the levers 3 with the cradles 16 transfer the products along the trajectory of the upper semicircle and smoothly place them in the technological position 21. The levers 3 when the product is repositioned perform a full turn, are fixed in the lower non-working position by a microswitch (not shown). When relocating the product from position 21

to position 20, levers 3 with lodgements 16 turn counterclockwise.

The common counterweight 7 serves to balance the levers 3 with the counterweight 5, lodgments 16, loaded products 19. During the product shifting process, the common counterweight 7 rotates on the semi-axle 8, while the torque of the common counterweight 7 has extreme values: maximum torque, when the cradles 16 with the products 19 are located in the upper part of the semicircle, the minimum ramification moment when the levers 3 pass the lower point where they are fixed (stopped; by means of a microswitch).

The mass of common counterweights is adjusted so that their torque balances the total torque generated by

levers 3, lodgements 16, counterweights 5. and half the mass of the products being shifted 19. This condition provides an increase in the load-carrying capacity of the products twice with the same power of the electric drive 2.

The coordinated interaction of the lodgements 16c of the product5 of the 19 counterweights 5 and the common counterweights 7 is provided by a rotational circular motion of the listed elements about two axes. The rotation of these elements 16, 15, 5 and 7 about two axes is achieved by the articulation of the shaft 9 of the levers 3

with electric drive 2 using gears 10, 11 and chain 14, and axes .6 with semi-axles in - using gears 12, 13 and chain 15.

Technological positions 20, 21 vary in level.

The proposed device will provide an increase in load capacity almost twice with the same power of the electric drive.
