Background

In the prior art, most tray lifts are used for placing empty trays, transferring and boxing the palletized trays and manually completing the palletized trays. When a worker places an empty tray or transfers a cargo tray, the tray lifting machine can only stay at the position where the empty tray or the cargo tray is placed, and the next operation can be performed after the worker finishes the operation. If the workers do not place empty trays or transport cargo trays in time, the hoisting machine can only be in a state of stopping operation all the time, so that a great amount of time is wasted, and the working efficiency is reduced. If the detecting system of the lifter malfunctions, when a worker places an empty tray and carries away a cargo tray, the tray lifter makes wrong judgment on the state of the tray, and then the tray lifter can be lifted or lowered suddenly when the worker does not complete the empty tray placement and cargo tray carrying away work, so that the tray lifter can be damaged, the use and maintenance cost of equipment is greatly increased, the personal injury to the worker is possibly caused, and meanwhile, the labor cost is increased.

The structures of the plugboard and the limiting plate are matched with the structure of the tray and are used for connecting the tray.

Further, the lifting mechanism comprises a gear motor 2-7 and four ball screws 2-1 arranged on four corners of the frame, wherein nuts 2-2 are arranged on the ball screws 2-1, nut connecting plates 2-3 are arranged on the nuts 2-2, and the nut connecting plates 2-3 are connected with the metal frame through screws and square nuts. Preferably, the gear motor is a gear motor with a band-type brake. The upper part of the ball screw 2-1 is provided with a first synchronous belt pulley 2-4, and the first synchronous belt pulleys 2-4 of the four ball screws are driven by a first synchronous belt (2-5, 2-6); the output shaft of the gear motor 2-7 is provided with a second synchronous pulley 2-8, and the second synchronous pulley 2-8 and a first synchronous pulley on the ball screw 2-1 are driven by a second synchronous belt 2-9. The gear motor 2-7 with the band-type brake can generate braking moment when not rotating, so that the tray can stably stay at a required position.

The operation of the pallet elevator is divided into four steps:

1. after the tray lifter is started, the tray lifter is firstly stopped at the upper part of the first station (see fig. 1), at the moment, piston rods of the first cylinders 3-6 at the two sides of the bearing translation mechanism 3 are in a retracted state, 4 self-picking plate unloading mechanisms 3-4 are positioned at the positions shown in fig. 1, piston rods of the second cylinders 3-4-2 in the self-picking plate unloading mechanisms 3-4 are also in a retracted state, and the left surfaces of the plate inserting mechanisms 3-4-6 are level with the left surfaces of the T-shaped plates 3-4-1.

The pallet elevator starts to determine whether empty pallets are placed on the second pallet seat 4-2 and the third pallet seat 4-3 at the first station. When an empty tray is detected, a gear motor 2-7 with a band brake in the lifting mechanism 2 starts to reversely rotate (see fig. 4) and drives a synchronous pulley 2-4 to reversely rotate through a synchronous pulley 2-8 and a synchronous belt 2-9, so that four ball screws 2-1 reversely rotate at the same time, and nuts 2-2 on the ball screws 2-1 synchronously descend. The metal frame 3-1 descends along with the screw nut 2-2, after the metal frame descends to a preset position, the gear motor 2-7 with the band-type brake stops rotating, the four ball screws 2-1 also stop rotating, the screw nut 2-2 stops descending, and accordingly the bearing translation mechanism 3 stops at the first station.

The piston rods of the second cylinders 3-4-2 in the 4 plugboard mechanisms 3-4 on the two sides of the metal frame 3-1 extend out simultaneously to drive the 4 plugboards 3-4-6 to be inserted into the gaps of the tray, and the 4 limiting plates 3-4-7 clamp the tray, so that the tray self-taking work is completed.

2. The gear motor 2-7 with band-type brake in the lifting mechanism 2 starts to rotate forward, the synchronous pulley 2-4 is driven to rotate forward through the synchronous pulley 2-8 and the synchronous belt 2-9, so that the four ball screws 2-1 are driven to rotate simultaneously, and the nuts 2-2 on the ball screws 2-1 rise synchronously. The aluminum alloy frame 3-1 rises together with the nuts 2-2, and after rising to the boxing and stacking height, the gear motor 2-7 with the band-type brake stops rotating, the four ball screws 2-1 also stop rotating, and the nuts 2-2 stop rising, so that the tray stops at the second station of the boxing and stacking height (see fig. 5).

3. The piston rod of the first air cylinder 3-6 extends out (see fig. 6), the piston rod drives the translation dragging plate 3-7 to move leftwards, and the translation dragging plate 3-7 drives the flashboard mechanism 3-4 to move leftwards, so that the tray enters the third station. At this station, the palletizing robot may perform a boxing or palletizing operation on the pallet.

4. After the boxing or stacking work is finished, the gear motor 2-7 with the band brake in the lifting mechanism 2 starts to reversely rotate, and the synchronous pulley 2-4 is driven to reversely rotate through the synchronous pulley 2-8 and the synchronous belt 2-9, so that the four ball screws 2-1 are driven to reversely rotate simultaneously, and the nuts 2-2 on the ball screws 2-1 synchronously descend. The aluminum alloy frame 3-1 descends along with the screw nut 2-2, after the aluminum alloy frame descends to the unloading height, the gear motor 2-7 with the band-type brake stops rotating, the four ball screws 2-1 also stop rotating, the screw nut 2-2 stops descending, and accordingly the tray is placed on the tray seats 4-1 and 4-2 at the fourth station.

The piston rods of the second cylinders 3-4-2, which are taken from the plug board unloading mechanisms 3-4, on the two sides of the aluminum profile frame 3-1 retract simultaneously to drive the 4 plug boards 3-4-6 to withdraw from the gaps of the tray, and the 4 limiting plates 3-4-7 are far away from the tray, so that the tray is unloaded.

Subsequently, the pallet elevator will detect whether an empty pallet is placed on the pallet seats 4-2 and 4-3 at the first station, and if a pallet is placed, the piston rod of the first cylinder 3-6 is retracted, the piston rod drives the translation dragging plate 3-7 to move rightward, and the translation dragging plate 3-7 drives the self-picking plate unloading mechanism 3-4 to move rightward together, and returns to the first station (see fig. 1). And the operation of the self-picking tray in the first step and the subsequent other steps are repeated.

If the tray lifter detects that no tray exists on the tray seats 4-2 and 4-3 at the first station, the tray lifter rises to the height of the second station, meanwhile, the piston rod of the first air cylinder 3-6 is retracted, the piston rod drives the translation dragging plate 3-7 to move rightwards, and the translation dragging plate 3-7 drives the self-picking and self-picking plate-unloading mechanism 3-4 to move rightwards together, returns to the position above the first station and waits for a worker to place an empty tray. After the worker places the empty tray, the tray lifter repeats the above steps one to four, and the work of self-taking the empty tray and self-unloading the pallet is completed repeatedly. In the utility model, whether the empty tray exists on the tray seat is detected by the sensor, and the operation of the device is controlled by the control system, and the operation is realized by adopting the prior art and is not repeated here.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
