[0042] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0043] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0044] In order to improve the automation level of palletizing workpieces, an automatic palletizing device is provided in this embodiment. Figure 1 As shown, the device includes a loading unit 10, a buffer unit 20, a unloading unit 30 and a palletizing assembly. The loading unit 10 includes a loading conveyor line 11 extending in a first direction, and the loading conveyor line 11 can convey workpieces in the first direction; the buffer unit 20 includes a buffer conveyor line 21 extending in a second direction (the first direction and the second direction are perpendicular to each other), and the buffer conveyor line 21 is connected to one end of the loading conveyor line 11, and the workpiece on the loading conveyor line 11 can be transferred to the buffer conveyor line 21 to buffer the workpiece; the unloading unit 30 includes a unloading conveyor line 31 extending in the first direction, and the unloading conveyor line 31 is connected to the buffer conveyor line 2 1, a plurality of stacking locations 32 are arranged on both sides of the unloading conveyor line 31 along the second direction, and a plurality of buffer locations 33 are arranged on the side of the stacking location 32 away from the unloading conveyor line 31; the stacking assembly includes a manipulator and a stacking forklift 40, the manipulator can stack the workpieces on the unloading conveyor line 31 to the stacking location 32 (the manipulator and the unloading conveyor line 31 are arranged on the same track to further improve the stacking efficiency), and the stacking forklift 40 can transport the workpieces on the stacking location 32 to the buffer location 33.

[0045] In this device, the workpieces can be continuously conveyed through the loading conveyor line 11, and when there are many workpieces, they can be cached through the buffer conveyor line 21, so as not to affect the continuous loading process; in addition, the other end of the buffer conveyor line 21 is connected to the unloading conveyor line 31, and the workpieces can be directly transferred to the unloading conveyor line 31 through the buffer conveyor line 21, and then the manipulator can take the workpieces from the unloading conveyor line 31 and stack them on the stacking location 32. After a sufficient number of workpieces are stacked in the stacking location 32, the stacking forklift 40 can move multiple workpieces at a stacking location 32 to the buffer location 33, so as to ensure that the workpieces can still be unloaded smoothly. In this transportation process, not only the labor cost and the number of workers are greatly reduced, but also the automation of the stacking of finished workpieces is improved, and the convenience of stacking is guaranteed. When a large number of workpieces are loaded at one time, the buffer conveyor line 21 can play the role of preliminary buffering of the workpieces, thereby ensuring the continuity of the loading conveyor line 11. As the manipulator works, the number of workpieces in the stacking location 32 continues to increase, and the stacking forklift 40 can also transfer the workpieces in a certain stacking location 32 to the stacking location 32 in time, thereby improving the convenience and continuity of the operation, avoiding excessive accumulation of workpieces in the stacking location 32 affecting normal unloading, and improving the convenience of use.

[0046] It is worth noting that if Figure 1As shown, the loading unit 10 of the equipment also includes a distribution station 13 and a labeling and weighing station 14. Before loading, the workpieces are labeled and weighed in the labeling and weighing station 14. After labeling and weighing, the staff distributes them to the loading conveyor line 11 through the distribution station 13, and the loading conveyor line 11 can convey the packaged workpieces along the first direction.

[0047] To further improve the feeding effect, Figure 1 As shown, a plurality of loading units 10 are arranged at intervals along the second direction, and a unloading unit 30 is arranged between each two adjacent loading units 10. In this structure, multiple loading units 10 can work and operate at the same time, thereby improving the efficiency of automatic operation. In addition, a unloading unit 30 is arranged between each two adjacent loading conveyor lines 11, so that the two loading conveyor lines 11 can share a unloading conveyor line 31, thereby further improving the smoothness of the operation.

[0048] Correspondingly, a plurality of buffer units 20 are also provided, and each feeding unit 10 is respectively connected to a corresponding buffer unit 20. In this structure, each feeding conveyor line 11 is correspondingly connected to a buffer unit 20, thereby ensuring that each feeding conveyor line 11 will not be blocked due to excessive feeding, thereby ensuring the continuity of work.

[0049] In addition, in order to improve space utilization, in the present embodiment, the buffer conveyor line 21 is arranged higher than the loading unit 10, and the buffer unit 20 also includes an elevator 22, and the two ends of the elevator 22 are respectively connected to the loading conveyor line 11 and the buffer conveyor line 21, so that the workpiece can be lifted to the buffer conveyor line 21. In this structure, the buffer conveyor line 21 is arranged higher than the loading conveyor line 11, which can provide a clearance space for the bottom surface to avoid obstructing the stacking forklift 40, and also improve the convenience of transporting the workpiece. In addition, by setting the elevator 22, the problem that the workpiece is inconvenient to move from the loading conveyor line 11 to the buffer conveyor line 21 can be solved. When the workpiece is transferred to the end of the loading conveyor line 11, the elevator 22 can lift the workpiece to the buffer conveyor line 21, thereby further ensuring the convenience of loading.

[0050] It should be noted here that in order to further increase the number of finished workpieces that can be accommodated in a workshop in addition to this equipment, such as Figure 1 As described above, a plurality of cache locations 33 are provided on the side of the cache unit 20 facing away from the loading unit 10. Since the cache conveyor line 21 is arranged above the loading conveyor line 11, the palletizing forklift 40 can directly transport the workpiece to the cache location 33 on this side, thereby increasing the capacity of the workshop for holding workpieces.

[0051] To facilitate subsequent palletizing, Figure 1As shown, the buffer unit 20 is provided with lifts 22 on both sides along the second direction, and the lifts 22 on the side away from the loading conveyor line 11 are connected to one end of the unloading unit 30. In this structure, the side of the buffer conveyor line 21 close to the loading conveyor line 11 can perform loading and caching work. When the buffer conveyor line 21 is full, it can be lowered to the bottom position through the lift 22 on the other side, and then the unloading and subsequent palletizing work can be completed through the unloading conveyor line 31 of the unloading unit 30, which ensures the convenience of loading and unloading, improves the degree of automation, and greatly reduces the number of labor and labor costs.

[0052] In addition, if Figure 1 As shown, each cache unit 20 includes a plurality of cache conveyor lines 21, and the plurality of cache conveyor lines 21 are arranged in parallel along the first direction. In this structure, each cache unit 20 has a plurality of cache conveyor lines 21, so that the cache quantity of finished workpieces can be further increased, ensuring good loading efficiency. In this embodiment, each cache unit 20 includes four cache conveyor lines 21, and the four cache conveyor lines 21 can be used to convey one or more workpieces to ensure work efficiency.

[0053] In addition, in order to facilitate caching of workpieces in each cache conveyor line 21, as Figure 1 As shown, the ends of the plurality of cache conveyor lines 21 are connected by a translation mechanism 23, and the elevator 22 is connected to the translation mechanism 23. When the workpiece is transferred to the elevator 22, the workpiece can be moved along the first direction by the translation mechanism 23, so that the workpiece can be switched between the plurality of cache conveyor lines 21, thereby avoiding the situation that one of the cache conveyor lines 21 is full of workpieces and cannot continue to store the workpieces; correspondingly, when unloading is required, the workpiece only needs to be moved to the elevator 22 by the translation mechanism 23, and then unloading can be performed. The loading efficiency and the convenience of operation are improved.

[0054] In this embodiment, a scanning mechanism 50 is further provided at one end of the unloading conveyor line 31 near the elevator 22. The scanning mechanism 50 is configured to recognize the QR code on the surface of the workpiece and remove defective products. After the workpiece is transferred from the buffer conveyor line 21 to the unloading conveyor line 31 through the translation mechanism 23 and the elevator 22, the scanning mechanism 50 can scan the QR codes on the surfaces of multiple workpieces one by one. When problems such as failure to recognize or errors in the recognition result occur during scanning, the scanning mechanism 50 can automatically remove the workpiece from both sides of the unloading conveyor line 31, thereby ensuring that the workpieces stacked by the robot are all good workpieces, ensuring the good product rate.

[0055] In addition, if Figure 1As shown, the feeding conveyor line 11 is provided with a sampling inspection station 12, which can perform sampling inspection on the workpieces on the feeding conveyor line 11. In order to ensure the yield rate, sampling inspection personnel can be arranged at the sampling inspection station 12 to perform sampling inspection on the workpieces. If there are problems such as unsealed, unlabeled, and overweight, the workpiece can be directly rejected. If there are no problems, the workpiece can be pushed back to the feeding conveyor line 11 to complete the subsequent palletizing work.

[0056] This embodiment also provides an automatic palletizing method, which is based on the above-mentioned automatic palletizing equipment. Specifically, the method includes the following steps:

[0057] S100, the operator labels and weighs the workpieces at the labeling and weighing station 14, and then distributes the workpieces at the distribution station 13 to transport the workpieces to the loading conveyor line 11;

[0058] S200, the sampling personnel can randomly sample and inspect the workpieces at the sampling station 12, and automatically remove the defective products;

[0059] S300, lifting multiple workpieces to the buffer conveyor line 21 by the elevator 22, and caching the workpieces on the multiple buffer conveyor lines 21 by the translation mechanism 23, so as to avoid the blocking of the feeding conveyor line 11 and a certain buffer conveyor line 21;

[0060] S400, lowering the multiple workpieces on the multiple buffer conveyor lines 21 to the unloading conveyor line 31 through the translation mechanism 23 and the elevator 22, and conveying the workpieces toward the stacking storage location 32 through the unloading conveyor line 31;

[0061] S500, the code scanning mechanism 50 sequentially identifies the two-dimensional codes on the surfaces of the multiple workpieces on the unloading conveyor line 31 to remove defective products from the multiple workpieces;

[0062] S600, after the unloading conveyor line 31 delivers the workpiece, the manipulator can stack the multiple workpieces correspondingly on the stacking location 32;

[0063] S700, the palletizing forklift 40 can move the workpieces on the palletizing location 32 to the buffer location 33 for buffering, thereby avoiding excessive accumulation of workpieces in the palletizing location 32, which would affect subsequent normal unloading.

[0064] In summary, the automatic palletizing method in this embodiment is based on the automatic palletizing equipment, which can greatly improve the degree of automation and palletizing efficiency, and can also reduce the number of manpower and labor costs.

[0065] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
