Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and in particular to a product grouping and sorting method. Background Art

[0002] In order to improve production efficiency, more and more automated equipment is being introduced in the industrial production process of products. As one of the indispensable equipment in the packaging industry, packaging machines are mainly used to group and package products. The packaged products, such as bottles and cans, are easy to transport and store, and can also play a certain protective role for bottles and cans with high requirements on appearance.

[0003] In order to achieve this goal, it is first necessary to group and organize several products or semi-finished products of the same specification. Generally, a bottle-driving rod with a circulating conveyor chain is set above the conveyor line, such as a bottle-driving mechanism with announcement number CN212448244U. The two chains are driven by two driving wheels, and the chains drive the bottle-driving assembly to circulate inside the frame. When the bottles in the bottle conveying channel are conveyed to the transition plate, the limit blocks of the bottle driving assembly contact with the bottles. According to the arrangement of the bottles, the limit blocks will abut against the corresponding bottles or make the bottles stuck in the gap between the two limit blocks, and then push the bottles to move on the transition plate, so that the bottles are gradually approached to achieve a compact arrangement effect to meet the requirements of subsequent packaging. In the actual production process, it is necessary to set a blocking mechanism in front of the bottle driving mechanism. When a group of products enters the bottle driving mechanism, the first product of the next group is blocked, and the next group of products will be sent in for sorting after the group of products on the bottle driving mechanism is finished. The actual efficiency is low in use, and when changing product specifications and combinations, the position of the bottle driving rod needs to be adjusted, which is inconvenient to adjust. There is room for improvement in the prior art. Summary of the invention

[0004] In view of the above existing situation, the present invention provides a product grouping and sorting method, using a first conveyor line and a second conveyor line arranged in sequence to convey products, the speed of the second conveyor line is greater than the speed of the first conveyor line, and the products are grouped by two groups of grouping mechanisms. The method includes: S1: Products pass through the first conveyor line and the second conveyor line in sequence. After the products enter the second conveyor line, the first grouping mechanism moves to the front of the first product entering the second conveyor line on the second conveyor line, and moves forward synchronously with the second conveyor line along with the first product in a group of products entering the second conveyor line; S2: A group of products are moved from the first conveyor line to the second conveyor line in sequence. Since the speed of the second conveyor line is greater than that of the first conveyor line, the distance between adjacent products is increased; S3: reduce the moving speed of the first grouping mechanism to block the first product in a group of products that enters the second conveyor line, so that the products in the same group are stacked against each other and leave a gap between them and the next group of products. After all the products in a group are moved to the second conveyor line, the second grouping mechanism starts S1; S4: After a group of products entering the second conveyor line are grouped and integrated, the first grouping mechanism is separated from the products, and the two grouping mechanisms operate alternately, repeating the above steps.

[0005] Preferably, in S1, the first grouping mechanism moves downward to the front of the first product entering the second conveyor line on the second conveyor line, and in S4, the first grouping mechanism rises to a position higher than the product, separates from the product and moves in the opposite direction along the conveying direction of the second conveyor line.

[0006] Preferably, the second conveying line and the first conveying line are respectively arranged on the packaging machine and the separation mechanism located at the front end of the packaging machine.

[0007] Preferably, a separation rack for conveying products in separate columns is provided on the separation mechanism along the conveying direction of the first conveyor line, and the grouping mechanism is located between the separation mechanism and the packaging machine.

[0008] Preferably, the grouping mechanism comprises a grouping rod for blocking the products to achieve grouping and a driving mechanism for driving the grouping rod to move.

[0009] Preferably, the driving mechanism includes a fixed seat, on which is movably provided a movable seat capable of moving along the length direction of the above-mentioned second conveyor line, on which is movably provided a lifting frame capable of moving along the vertical direction, the above-mentioned grouping rod is fixedly provided at the lower end of the lifting frame, and the lifting frame and the movable seat are moved by a cross-shaped circulating conveyor belt provided on the fixed seat.

[0010] Preferably, two driving motors are fixedly arranged on the fixed seat to drive the cross-shaped circulating conveyor belt to move and drive the movable seat and the lifting frame to move.

[0011] Preferably, a connecting plate for supporting the movement of products is provided between the first conveying line and the second conveying line.

[0012] Preferably, a plurality of partitions are fixedly arranged in the partition rack, and the distance between two adjacent partitions is greater than the diameter of the product.

The extension plate is located above the second conveyor line and a certain gap is left between the extension plate and the second conveyor line.

[0014] Preferably, the extension plate is located at the lower end of the partition plate on the side facing the second conveyor line.

[0015] Compared with the prior art, the present invention separates grouping and packaging. Products are grouped in advance by a grouping mechanism before packaging, and then the overall moving speed of the product is controlled by adjusting the first conveyor line and the second conveyor line, so that the first conveyor line is always in a conveying and feeding state.

DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: 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 in sequence to convey products, the speed of the second conveyor line 4 is greater than the speed of the first conveyor line 3, and the products are grouped by two groups of grouping mechanisms 7. The method includes: S1: Products pass through the first conveyor line 3 and the second conveyor line 4 in sequence, and the first grouping mechanism 7 moves to the front of the first product entering the second conveyor line 4 on the second conveyor line 4, and moves forward synchronously with the second conveyor line 4 along with the first product in a group of products entering the second conveyor line 4; S2: A group of products are moved from the first conveyor line 3 to the second conveyor line 4 in sequence. Since the speed of the second conveyor line 4 is greater than that of the first conveyor line 3, the distance between adjacent products is increased; S3: reduce the moving speed of the first grouping mechanism 7 to block the first product in a group of products entering the second conveyor line 4, so that the same group of products are stacked against each other and leave a gap between the next group of products. After all the products in a group are moved to the second conveyor line 4, the second grouping mechanism 7 starts S1; S4: After the grouping and integration of a group of products entering the second conveyor line 4 is completed, the first grouping mechanism 7 is separated from the products, and the two grouping mechanisms 7 operate alternately, and the above steps are repeated.

[0023] In the S1, the first grouping mechanism 7 moves downward to the front of the first product entering the second conveyor line 4 on the second conveyor line 4. In the S4, the first grouping mechanism 7 rises to a position higher than the product, separates 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 arranged 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 provided with a sorting rack 5 for sorting and conveying the products along the conveying direction of the first conveyor line 3. The packaging machine 1 is provided with a packaging mechanism 6 for further processing the grouped products. The grouping mechanism 7 is located between the sorting rack 5 and the packaging mechanism 6, and the grouping and packaging are separated. The products are grouped in advance by the grouping mechanism 7 before packaging. Then, 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 a conveying and feeding state, and the overall product conveying process is smoother, which effectively improves the efficiency of grouping and packaging.

[0024] A connecting plate 14 for supporting the movement of products is provided between the first conveyor line 3 and the second conveyor line 4. A plurality of partitions 15 are fixedly provided in the column rack 5, and the distance between two adjacent partitions 15 is greater than the diameter of the product. An extension plate 16 extending toward the second conveyor line 4 is fixedly provided at the lower end of the partition 15 located near one end of the first conveyor line 3, and the extension plate 16 is located above the second conveyor line 4 and has a certain gap between the extension plate 16 and the second conveyor line 4. The extension plate 16 is located at the lower end of the partition 15 facing the second conveyor line 4, and the extension plate 16 allows the products to continue to move in columns after entering the second conveyor line 4, so that the grouping mechanism 7 can perform grouping.

[0025] The grouping mechanism 7 includes a grouping rod 11 for blocking the above-mentioned products to achieve grouping and a driving mechanism for driving the grouping rod to move. The driving mechanism includes a fixed seat 8 fixedly arranged on the above-mentioned packaging machine 1, and a movable seat 9 that can move along the length direction of the above-mentioned second conveyor line 4 is movably arranged on the fixed seat 8. A lifting frame 10 that can move along the vertical direction is movably arranged on the movable seat 9. The above-mentioned grouping rod 11 is fixedly arranged at the lower end of the lifting frame 10, and the lifting frame 10 and the movable seat 9 are moved by a cross-shaped circulating conveyor belt 12 arranged on the fixed seat 8. Two driving motors 13 for driving the above-mentioned cross-shaped circulating conveyor belt 12 to move and drive the movable seat 9 and the lifting frame 10 to move are fixedly arranged on the fixed seat 8. The grouping mechanism 7 using this method can adapt to products of different specifications and is easy to adjust. Through the speed difference between the first conveyor line 3 and the second conveyor line 4, when the product enters the second conveyor line 4 from the first conveyor line 3, due to the faster speed of the second conveyor line 4, a certain gap is left between adjacent products, and 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, and the grouping rod 11 moves synchronously with the first product in a group of products. After the grouping rod 11 moves a certain distance, the speed of the grouping rod 11 is reduced to block the first product in a group of products. At the same time, the grouping rod 11 on the second grouping mechanism 7 falls and moves with the subsequent products. The first group of products is piled up into groups under the obstruction of the slower grouping rod 11, and the grouping rod 11 moves upward and then detaches. The whole 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 in turn to complete the grouping, so that the product is always in a moving state 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.

[0026] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, the obvious changes or changes in the description derived therefrom are still within the scope of protection of the present invention.
