Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and in particular to a product grouping and sorting method. Background Technology

[0002] To improve production efficiency, more and more automated equipment is being introduced into the industrial production process of products. As one of the indispensable pieces of equipment in the packaging industry, packaging machines are mainly used to group and package products. Packaged products, such as bottles and cans, are easy to transport and store, and can also provide a certain degree of protection for bottles and cans with high appearance requirements.

[0003] To achieve this goal, it is first necessary to group and sort several products or semi-finished products of the same specifications. Generally, a bottle-driving rod with a circulating conveyor chain is set above the conveyor line. For example, a bottle-driving mechanism with announcement number CN212448244U drives two chains through two drive wheels. The chains drive the bottle-driving components to circulate inside the frame. When bottles are conveyed to the transition plate in the bottle conveying channel, the limiting blocks of the bottle-pushing assembly contact the bottles. Depending on the arrangement of the bottles, the limiting blocks will abut against the corresponding bottles or cause the bottles to be stuck in the gap between two limiting blocks, thus pushing the bottles to move on the transition plate, thereby gradually bringing the bottles closer together to achieve a compact arrangement and meet the requirements of subsequent packaging. In actual production, a blocking mechanism needs to be set in front of the bottle-pushing mechanism. When a group of products enters the bottle-pushing mechanism, the first product of the next group is blocked, and the next group of products is not fed in until the group of products on the bottle-pushing mechanism has been sorted. In actual use, the efficiency is low, and when changing product specifications and combinations, the position of the bottle-pushing rod needs to be adjusted, which is inconvenient. The existing technology has room for improvement. Summary of the Invention

[0004] This invention addresses the aforementioned shortcomings by providing a product grouping and sorting method. The method utilizes a first conveyor line and a second conveyor line arranged sequentially to transport products. The speed of the second conveyor line is greater than that of the first conveyor line. The products are grouped using two sets of grouping mechanisms. The method includes:

[0005] S1: The product passes through the first conveyor line and the second conveyor line in sequence. After the product enters the second conveyor line, the first grouping mechanism moves in front of the first product that enters the second conveyor line and moves forward synchronously with the second conveyor line along with the first product in a group.

[0006] S2: A group of products moves sequentially from the first conveyor line to the second conveyor line. Because the speed of the second conveyor line is greater than that of the first conveyor line, the distance between adjacent products is increased.

[0007] S3: Reduce the moving speed of the first grouping mechanism to block the first product in a group of products from entering the second conveyor line, so that the products in the same group are pushed against each other and leave a gap between them and the next group of products. After all the products in a group have moved to the second conveyor line, the second grouping mechanism starts S1.

[0008] S4: After a group of products entering the second conveyor line is grouped and integrated, the first grouping mechanism is separated from the products, and the two grouping mechanisms operate alternately, repeating the above steps.

[0009] Preferably, in step S1, the first grouping mechanism moves downward to the front of the first product entering the second conveyor line, and in step S4, the first grouping mechanism rises to a position higher than the product, detaches from the product, and moves in the opposite direction along the conveying direction of the second conveyor line.

[0010] Preferably, the second conveyor line and the first conveyor line are respectively installed on the packaging machine and the sorting mechanism located at the front end of the packaging machine.

[0011] Preferably, the sorting mechanism is provided with a sorting frame for sorting and conveying products along the conveying direction of the first conveyor line, and the sorting mechanism is located between the sorting mechanism and the packaging machine.

[0012] Preferably, the grouping mechanism includes a grouping rod for preventing the products from being grouped and a drive mechanism for driving the grouping rod to move.

[0013] Preferably, the driving mechanism includes a fixed base, on which a movable base is movably mounted and movable along the length of the second conveyor line, and on which a lifting frame is movably mounted and movable along the vertical direction, and the grouping rod is fixedly mounted at the lower end of the lifting frame, and the lifting frame and the movable base move together via a cross-shaped circulating conveyor belt mounted on the fixed base.

[0014] Preferably, the fixed base is equipped with two drive motors for driving the cross-shaped circulating conveyor belt to move and driving the movable seat and the lifting frame to move.

[0015] Preferably, a connecting plate for supporting product movement is provided between the first conveyor line and the second conveyor line.

[0016] Preferably, the rack is equipped with multiple partitions, and the distance between two adjacent partitions is greater than the diameter of the product.

[0017] Preferably, an extension plate extending toward the second conveyor line is fixedly provided at the lower end of the partition plate near the first conveyor line. The extension plate is located above the second conveyor line and has a certain gap with the second conveyor line.

[0018] Preferably, the extension plate is located at the lower end of the partition on the side facing the second conveyor line.

[0019] Compared with the prior art, the present invention separates grouping and packaging. Before packaging, the products are grouped in advance by a grouping mechanism. Then, the overall moving speed of the products is controlled by adjusting the first conveyor line and the second conveyor line, so that the first conveyor line is always in the conveying and feeding state. The overall product conveying process is smoother and the efficiency of grouping and packaging is effectively improved. Attached Figure Description

[0026] The present invention will be further described below with reference to the embodiments illustrated in the accompanying drawings:

[0027] like Figure 1-5 As shown, a product grouping and sorting method uses a first conveyor line 3 and a second conveyor line 4 arranged sequentially to transport products. The speed of the second conveyor line 4 is greater than the speed of the first conveyor line 3. The products are grouped by two sets of grouping mechanisms 7. The method includes:

[0028] S1: The products pass through the first conveyor line 3 and the second conveyor line 4 in sequence. The first grouping mechanism 7 moves to the front of the first product entering the second conveyor line 4 and moves forward synchronously with the second conveyor line 4 along with the first product in a group.

[0029] S2: A group of products moves sequentially from the first conveyor line 3 to the second conveyor line 4. Since the speed of the second conveyor line 4 is greater than the speed of the first conveyor line 3, the distance between adjacent products is increased.

[0030] S3: Reduce the moving speed of the first grouping mechanism 7 to block the first product in a group of products from entering the second conveyor line 4, so that the products in the same group are pushed against each other and leave a gap between them and the next group of products. After all the products in a group have moved onto the second conveyor line 4, the second grouping mechanism 7 starts S1.

[0031] S4: After a group of products entering the second conveyor line 4 is grouped and integrated, the first grouping mechanism 7 is separated from the products, and the two grouping mechanisms 7 operate alternately, repeating the above steps.

[0032] In step S1, the first grouping mechanism 7 moves downward to the front of the first product entering the second conveyor line 4. In step S4, the first grouping mechanism 7 rises to a position higher than the product, detaches from the product, and moves in the opposite direction along the conveying direction of the second conveyor line 4. The second conveyor line 4 and the first conveyor line 3 are respectively installed on the packaging machine 1 and the sorting mechanism 2 located at the front end of the packaging machine 1. The sorting mechanism 2 is equipped with a sorting rack 5 for sorting and conveying products along the conveying direction of the first conveyor line 3. The packaging machine 1 is equipped with a packaging mechanism 6 for further processing of the grouped products. The grouping mechanism 7 is located between the sorting rack 5 and the packaging mechanism 6, separating the grouping from the packaging. Before packaging, the products are grouped in advance by the grouping mechanism 7. The overall moving speed of the products is controlled by adjusting the first conveyor line 3 and the second conveyor line 4, so that the first conveyor line 3 is always in the conveying and feeding state. The overall product conveying process is smoother, effectively improving the efficiency of grouping and packaging.

[0033] A connecting plate 14 for supporting product movement is provided between the first conveyor line 3 and the second conveyor line 4. Multiple partitions 15 are fixedly installed inside the sorting rack 5, with the distance between adjacent partitions 15 greater than the diameter of the product. An extension plate 16 extending towards the second conveyor line 4 is fixedly installed at the lower end of one of the partitions 15 near the first conveyor line 3. This extension plate 16 is located above the second conveyor line 4 and has a certain gap with it. The extension plate 16 is located at the lower end of the partition 15 facing the second conveyor line 4, allowing the products to continue moving in columns after entering the second conveyor line 4, facilitating grouping by the grouping mechanism 7.

[0034] The grouping mechanism 7 includes a grouping rod 11 for blocking the products from being grouped and a drive mechanism for driving the grouping rod to move. The drive mechanism includes a fixed base 8 fixedly mounted on the packaging machine 1. A movable base 9 movably mounted on the fixed base 8, capable of moving along the length of the second conveyor line 4, is movably mounted on the movable base 9. A lifting frame 10 movably mounted on the movable base 9, capable of moving in the vertical direction, is also movably mounted on the movable base 9. The grouping rod 11 is fixedly mounted at the lower end of the lifting frame 10. The lifting frame 10 and the movable base 9 move via a cross-shaped circulating conveyor belt 12 mounted on the fixed base 8. Two drive motors 13 are fixedly mounted on the fixed base 8 to drive the cross-shaped circulating conveyor belt 12 and move the movable base 9 and the lifting frame 10. This grouping mechanism 7 can adapt to products of different specifications and is easy to adjust. Due to the speed difference between the first conveyor line 3 and the second conveyor line 4, when products enter the second conveyor line 4 from the first conveyor line 3, a certain gap is left between adjacent products because the second conveyor line 4 moves faster. At the same time, the moving speed of one of the grouping rods 11 is the same as the speed of the second conveyor line 4. The grouping rod 11 moves synchronously with the first product in a group. After the grouping rod 11 moves a certain distance, its speed decreases to block the first product in the group. At the same time, the grouping rod 11 on the second grouping mechanism 7 falls down and moves with the subsequent products. The first group of products is blocked by the slower-moving grouping rod 11 and piles up into a group. After the grouping rod 11 moves upward, it detaches. The entire group of products moves with the second conveyor line 4 to the packaging mechanism 6 for packaging. The two grouping mechanisms 7 move in a cycle to complete the grouping, so that the products are always in motion during the conveying process. The first conveyor line 3 does not need to stop and wait, the material flow is smoother, and the grouping is faster.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications to the specification derived therefrom are still within the scope of protection of this invention.
