Device for handling piece goods 1 includes receiving and feeding coveyors 2 and 3, a vertical lifting device in the form of vertical chain conveyors 4 and 5, placed between the latter in the upper part of them on the ramp 6 a horizontal chain transfer conveyor 7 and transfer mechanisms between conveyors 4 and 5 and conveyor 7, overload mechanisms are mounted on the ends of the conveyor 7 and are made in the form of rotating blocks 8, each of which consists

associated with the actuator 9 spline shaft 10, diametrically mounted on it two cantilever comb elements 11 and placed on the shaft between the last spacer bushings 12 25 and a set of freely rotating sprockets 13 mounted on the shaft 10 through bearings 14. Sprockets 13 are connected through chain contours 15 with sprockets 16 mounted on shaft 30 17, on which are mounted end sprockets 18 of conveyor 7 consisting of several parallel chains. One of the shafts 17 of the conveyor 7 is connected to the drive 19. Vertical conveyors 4 and 5 include chains 20, on a pair of connecting rods 21 of the links of which, by means of spacer sleeves 22 and fastening nuts 23, we assemble the comb-shaped platforms 40 of us 24. Chains 20 span sprockets

• 25 mounted on a splined shaft
• 26 associated with the actuator 27. At the ends of the platforms, nipples 28 of polyamide materials are made. On shaft 26

45 is mounted a drum 29 with beveled surfaces for the passage of platforms 24. Vertical chain conveyors 4 and 5 are mounted on support 30 and have a frame 31. Above the conveyors 4, 5 and 7 an upper slab 32 is mounted. On the frame 31, guides 32 and 33 are mounted for vertical branches of chains 20; The rollers 34 of the chains 20, mounted on the rods 35, cooperate with the guides. The platforms 24 are installed on the chains 20 with uniform pitch (the pitch between the platforms 24 is reduced 2 times in Fig. 12) The teeth of the platform 24 are installed with

• 5 offset by 1/2 step relative to the I teeth of the comb elements 11 for passing between them. Vertical chain conveyors are equipped with radial valves 37 mounted on hinges 36, which are held in their initial position by clamps 38. Receiving and transmitting conveyors are made in the form of tapes with a set of pads 39, between which pro-longitudinal grooves are formed to accommodate the ends of the flaps 37 and platform teeth 24. The speed of the chain loops 15 and the conveyor 7 and their asterisks is four times as large as the speed of rotation of the comb elements 11.

The device works as follows.

Received piece cargo 1 (for example, in the car) is placed on the load-carrying belt of the conveyor belt 2, moving to a closed radius valve 37 (Fig.1-9), the end of which protrusions fit into the grooves formed by the blocks of the load-carrying belt of the conveyor belt 2. The load 1 slides the radial surface of the valve 37 movement belt conveyor, at this time console, platform 24 of the vertical conveyor 4, moving along the radius, partially go into the slots of the load-carrying belt belt conveyor 2, fall asleep cargo up the radius of the dampers 37 and gripper are placed on the load-carrying platform 24, and then conveyed upward.

The base of the cantilever platform 24 slides along the wall of the conveyor body 4, and the rollers of the 34 links of the traction chain 20 slide between the outer 32 and inner 33 guides. The cantilever platform 24, reaching the base of the plane of the drum 29, moves along the radius together with the drum, passing with the upper asterisks along the radius and reaching a certain angle of inclination, the load 1 slides along the platform to the base, and then falls on the approaching ridge element 11 of the transfer mechanism, the movement of which combined with the interval of movement of the cantilever platform 24 of the conveyor 4, configured by means of a toothed ν-shaped clutch drive gear mechanism.

su reaches a certain angle. slope, where the load slides down and falls onto the load-carrying web of the prefixes of the chain loops 15. Here the load moves at least four times the optimum speed compared to the speed of the drum of the transfer mechanism, bypassing the load moving along the radius of the comb member 11. Then the load is transported load-bearing surface of the chain horizontal conveyor belt 7 to the second transfer mechanism. Here, the load is sent to the cantilevered coarse element 11 of the transfer mechanism, and as the block 8 moves along the radius and reaches a certain angle of inclination by the cantilever comb element 11, the load slides and (is captured) is transferred to the console platform 24 of the conveyor. with

When switching the conveyor drives of the control panel to reverse movement, the right flap 37 of the right branch of the conveyor 5 closes. The load is placed on the carrying belt of the conveyor 3, moves to the closed radius valve 37 and the capture of the cantilever platform moving along the radius is sent upwards along the radius of the valve 37, laying down on the platform 24 and being transported upwards. The platform 24 is moving, passing through the drum of the upper sprockets 25 and reaching the angle of inclination, the load slides and falls on the comb element 11 of the transfer mechanism. Combing element 11, moving along the radius, shifts the load onto the chain loops 15 and the conveyor, puts it onto the transfer mechanism, “further similarly the load follows to the destination (for example, into a wagon).

The drive of the horizontal multi-row chain conveyor 7 and its chain contours 15 have at least four times the linear speed relative to the movement of the load-carrying cantilever platforms 24 of the conveyors 4 and 5 (FIG. 1) and the cantilevered comb elements 11 of the transfer mechanism.

The transfer mechanism drives are equipped with adjusting toothed ν-shaped couplings for angular adjustment (adjustment) of matching the required kneading angle of cantilever comb elements 11 transfer mechanisms of cantilever platforms 24 vertical conveyors 4 and 5 (figure 1) during load transfer by platforms during synchronous operation and reverse movement conveyors from the control panel.
