Description

The invention relates to the automation of hoisting and storage operations, namely, devices for centering products, mainly containers on the cargo platform of a stacker crane, and can be used in the shipbuilding and engineering industries.

The purpose of the invention is the expansion of technological capabilities by using it on cargo platforms of stacker cranes.

FIG. 1 shows a device for centering products, top view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 — node I in FIG. 3

The device comprises a support platform 1 mounted on a cargo platform 2 with the possibility of vertical movement relative to the telescopic gripper 3 and the centering mechanism, which includes two centering bodies 4 and 5 rigidly mounted on movable rods, made each of two parts into each other 6 and 7, 8 and 9, spring-loaded springs 10 and 11 compression. The rods synchronously move in guide sleeves 12 and 13 towards each other by means of screw gears 14 and 15 from the actuator 16. In sleeves 12 and 13 there are guide bayonet grooves 17 and 18, respectively, having straight and spiral portions, which include pins 19 and 20, rigidly connected to parts 7 and 9 of the rods.

Parts 7 and 9 of the tongs contain longitudinal grooves 21 and 22, which include pins 23 and 24, which are rigidly connected to parts 6 and 8 of the rods. On the cargo platform 2 mounted stops 25 and 26, limiting the output of the centering bodies 4 and 5 for its size. On the supporting platform 1, on both sides, switches 27 are installed to control the displacement of the container by means of test probes 28, which are dummy: spring-loaded springs 29 with a vertical stroke, limited by an emphasis 30, and act on switches 27 by bark 31.

The device for centering products works as follows.

To take the container out of the rack cell, the movable frame of the telescopic gripper 3 extends, picks up the container and returns to its original position. The support platform 1, together with the switches 27 fixed on it, rises upwards, thus moving both control nj.yna 28.

In the case of a central location of the container on the grip 3, both control

 A probe 28, left and right, will be pressed into the bottom of the container and, compressing the spring 29, will act the bark 31 on the limit switches 27.

According to the signals of the limit switches 27

5, the support platform 1 stops and descends to its original position. In the case of a non-central location of the container on the grip 3, only one of the probes 28, for example, the right one (against the right displacement of the container), abuts against the bottom of the container.

0 In this case, the lifting of the support platform 1 continues, and the probe 28, abutted against the stop 30, stops, compressing the spring 29, and loses contact with the container.

The signal from the switch 27 turns on the actuator 16 and, through the screw gears 14 and 15, drives the rods 7 and 9 placed in the sleeves 12 and 13, guided by the bayonet slots 17, 18 and shields 19, 20. Parts 7 and 9 rods through pins 23 and 24 set in motion part 6

0 and 8 rods and centering bodies 4 and 5 fixed on them. The latter are turned into a vertical working position and synchronously move towards each other, the center of a container located on the rollers of the raised support platform 1.

 At the end of the centering, the support platform 1 returns to its original (lower) position, while lowering the container on the grip 3. The actuator 16 is turned on the reverse, the gear screws 14 and 15 rotate in

0 reverse direction, moving to the initial position of part 7 and 9 of the rods. Parts 6 and 8 of the rods, together with the centering bodies 4 and 5, move longitudinally, then, resting against the stops 25 and 26, unfold in a "place to the initial position,

 compressing the springs 10 and 11 and moving the pins 23 and 24 in the slots 21 and 22.
