Description

Automatic unpacking device

technical field

The invention relates to a box unwinding device, in particular to an automatic box unwinding device that does not require manual unloading and is not limited by space conditions.

Background technique

In the process of industrial and agricultural production, there are often a large number of articles or workpieces that need to be boxed and frequently taken out and stored in the box. When the number of these items or workpieces is large and many boxes are required, in order to reduce the space occupied or transported, the boxes are generally stacked. The conventional stacking method uses direct stacking between boxes, and this stacking method It is inconvenient to pick and place the items or workpieces in each box. It is necessary to remove the boxes containing unnecessary items or workpieces to get the desired items or workpieces. Sometimes, due to space constraints, it is even necessary to move the container The boxes of unnecessary articles or workpieces are moved far away, which is time-consuming and labor-intensive, and also increases labor costs. Such a situation is very common in the transportation industry, where different items or workpieces are stored in the boxes in the carriage or container, but along the way, according to the needs of customers, the items or workpieces in the boxes of different items or workpieces are picked and placed. It is time-consuming and labor-intensive, the labor intensity of workers is high, and the labor cost is also high. The same situation can be encountered in large factories, especially for inspection and assembly work.

However, there is no device in the prior art that can solve the above problems, that is, manual labor is still used to store and take out the goods in the container, which is time-consuming, labor-intensive and costly.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide an automatic box-empty device that does not require manual box-flushing and is not limited by space conditions.

The present invention is achieved through the following technical solutions. An automatic box-reversing device includes a frame for packing at least two layers of identical boxes. Support rails composed of rollers on the same layer on the longitudinal inner side at both ends;

A horizontal transmission mechanism is arranged above or below each layer of the box, and the horizontal transmission mechanism includes a horizontal motor and a push-pull block driven by the horizontal motor through a screw;

A synchronous lifting mechanism is provided at the front and rear ends of the frame. The synchronous lifting mechanism is composed of two groups of lifting mechanisms respectively arranged at the front and rear ends of the frame. Lifting cable, the front end of the lifting cable is connected to the vertical block and the hook at the bottom of one end of the box to be raised, the other end of the lifting cable passes through the frame and pulleys longitudinally, and is connected to another vertical block at the rear end of the frame and is located at the bottom of the box to be lowered. The hook at the bottom of one end of the box;

In the vertical lifting path of the box, starting from the second layer of the box, at the same height of the columns on both sides of the frame at the front end of the support rail, there is a support pin that shrinks as the box rises and squeezes;

Both the horizontal conveying mechanism and the synchronous lifting mechanism are controlled by a PLC controller.

The steps of moving the box each time are as follows: the horizontal transmission mechanism on the lower layer first pushes and pulls the box at the first place in the longitudinal direction of the layer backward by a distance of the thickness of the box by the push-pull block driven by the horizontal motor through the screw rod, so that the The box at the end of the layer moves backward and is located on the hook of the lifting mechanism, and then the push-pull block is reset to leave a space in this layer; the synchronous lifting mechanism works, and the aforementioned horizontally moved box is lifted to a higher level through the hook , and is supported by the supporting pins, and at the same time, the lifting mechanism descends synchronously at the rear end of the frame to move the first box in the upper layer to the vacancy of the lower layer, and the synchronous lifting mechanism resets; the push-pull of the horizontal transmission mechanism on the higher layer The block pushes and pulls the box body at the last position of the layer forward by a distance of the thickness of the box body, so that the first box body of the layer moves forward and is located on the supporting hook of the lifting mechanism, and then the push-pull block resets.

The present invention has the advantages of adopting the above-mentioned structure: it realizes the automatic container dumping, and it is not restricted by the space conditions at the same time.
