Description

A suitcase transfer device

technical field

The invention belongs to the technical field of machinery, and relates to a suitcase transfer device, in particular to a suitcase transfer device for a refrigerator/freezer production line.

Background technique

In the refrigerator/freezer manufacturing industry, it is necessary to manufacture the cabinet of the refrigerator/freezer first, and then install other parts in the cabinet of the refrigerator/freezer. The box body of the refrigerator/freezer is formed by foam molding, and the formed refrigerator/freezer is placed in the mold and conveyed out by the foaming line. The refrigerator/freezer is separated from the mold and transported to the output line. This process is called refrigerator/freezer transfer. At present, this transfer process is generally completed in the following two ways:

The first way is: take the refrigerator/freezer out of the mold manually by workers, and then put it on the output line and transport it to the next process. Such manual transfer has problems such as low work efficiency, high labor intensity, and high required cost.

The second way is: by means of manipulators. For example, the Chinese patent literature discloses a multi-station refrigerator box foaming production line equipment [patent number: ZL201010594001.5; authorized announcement number: CN102029679A]. Refrigerator box foaming production line equipment adopts rails and trolley tracks on the frame, and mold trolley rails on the foundation. The mold trolley transports the foaming mold to the foaming station through rack and pinion transmission, and the foaming manipulator is on the trolley. It runs on the track to the foaming station, and the foaming mixing head is driven up and down by the lifting of the cylinder, so that the foaming mixing head can foam the refrigerator box on the foaming station, and at the same time, the pick-up manipulator runs on the track, and the pick-up manipulator passes through The expansion and contraction of the lifting cylinder and the connecting rod mechanism drive the vacuum suction cup to lift the foamed refrigerator box away from the foaming mold, so that the foaming mixing head can continuously foam the refrigerator box at multiple foaming stations, and at the same time The transfer process of the refrigerator cabinet has also been realized. In this way, the transfer process through the manipulator is more efficient and less labor-intensive than manual transfer. However, when using the manipulator, the foaming line needs to be temporarily stopped, which affects the conveying efficiency of the foaming line. Simultaneously, also partly reduced transfer efficiency, wasted time, improved cost.

Contents of the invention

In view of the above-mentioned problems in the existing technology, the present invention proposes a suitcase transfer device, which can realize the automatic transfer of refrigerators/freezers and improve the transfer efficiency.

The present invention is realized through the following technical solutions: a suitcase transfer device, which is characterized in that the suitcase transfer device includes a bracket, a ring-shaped guide rail arranged on the bracket, and a plurality of ring-shaped guide rails arranged below the ring-shaped guide rail for holding the refrigerator/ As for the clamping mechanism of the refrigerator, a lifting mechanism is provided between each clamping mechanism and the annular guide rail, the upper part of the lifting mechanism is rollingly connected to the circular guide rail, and the lower part of the lifting mechanism is fixedly connected to the clamping mechanism And rollers are set at the bottom of the lifting mechanism, and a ring-shaped lifting guide rail is also provided under the annular guide rail.

The suitcase transfer device is set between the foaming line and the output line, and is used to take out the refrigerator/freezer on the foaming line from the mold and transfer it to the output line. Under the action of the bracket, the ring guide rail is in the air between the foaming line and the output line. When the refrigerator/freezer installed in the mold on the foaming line is transported under one of the clamping mechanisms, first, the clamping mechanism Under the action of the mechanism, the refrigerator/freezer is clamped; secondly, under the action of the power mechanism, the lifting mechanism moves along the circular guide rail, and the rollers at the lower part of the lifting mechanism act on the lifting guide rail, and the lifting mechanism slowly rises. At the same time, The lifting mechanism also slowly retracts upwards, and the straight path shrinks to the minimum value, and the clamping mechanism fixed at the lower part of the lifting mechanism also rises upwards; then, under the continuous action of the power mechanism, the lifting mechanism moves along the circular guide rail for a period of time Finally, the rollers at the lower part of the lifting mechanism descend along the lifting guide rail, and the lifting mechanism slowly opens downward until it reaches the maximum value. At this time, the clamping mechanism and the refrigerator/freezer of the clamping mechanism are just above the output line; Finally, the clamping mechanism releases the refrigerator/freezer, and the refrigerator/freezer enters the output line; the released clamping mechanism returns to the foaming line along the ring guide rail with the lifting mechanism, and the next group of refrigerators/freezers Prepare for the transfer of the freezer. Through the above process, the refrigerator/freezer on the foaming line is automatically taken out from the mold and transferred to the output line. Since the refrigerator/freezer on the foaming line can be transferred without stopping, the transfer effect of the refrigerator/freezer is improved, the automation level is promoted, and the competitiveness of the enterprise is improved.
