Description

Technical Field

[0001] The utility model belongs to the technical field of sorting and arranging devices, and in particular relates to a folding spoon sorting and arranging device. Background Art

[0002] Folding spoons are disposable tableware made of plastic, usually made by one-piece injection molding using the injection molding process. Generally, multiple injection molding machines are arranged in the processing workshop. Granular plastic raw materials enter the injection molding equipment, melted at high temperature and extruded into the mold cavity. After cooling, they are formed and demolded, and then transferred to the conveyor line by a robot, thus forming a continuous production process. After injection molding, the folding spoons that pass the inspection will flow to the packaging process, and those that fail the inspection need to be sorted out and treated as waste. In order to improve the efficiency and effect of inspection, existing processing lines usually introduce visual inspection systems, which use cameras to take images of the folding spoons from above and compare them with standard product images. Injection defects such as insufficient injection, dents, and overflow can be found.

[0003] Therefore, the folding spoon production line needs to be equipped with a sorting and arranging device. Sorting refers to separating defective products as waste, while arranging refers to placing qualified products in a relatively stable position and transporting them to the packaging equipment via a conveyor line. The existing technology lacks such an integrated sorting and arranging device, and it needs to be developed and designed according to the needs. Utility Model Content

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given to illustrate in detail.

[0020] See Figure 1 、 Figure 2 and Figure 3 The folding spoon sorting and arranging device of the present invention includes a lifting housing 4 driven by multiple lifting cylinders 2. Two parallel front and rear sorting and arranging assemblies are located within the lifting housing 4. The lifting housing 4 encloses the two sorting and arranging assemblies, thereby reducing the number of exposed moving parts and effectively preventing foreign matter from entering the sorting and arranging assemblies and causing jamming. The front and rear sorting and arranging assemblies operate independently, making the folding spoon sorting and arranging device a dual-station device, improving operational efficiency.

[0021] In this embodiment, multiple mounting plates 3 are mounted on the top wall of the lifting box 4. The upper ends of the pistons of each lifting cylinder 2 are fixedly connected to each mounting plate 3. The system also includes multiple mounting base plates 1, which are fixedly connected to the equipment rack. The lower ends of the cylinders of each lifting cylinder 2 are fixedly connected to each mounting base plate 1. As shown in the figure, two lifting cylinders 2 are provided. During operation, the two lifting cylinders 2 operate synchronously, causing the lifting box 4 and its accessories to move upward and downward.

[0022] like Figure 1As shown in the figure, the sorting and arranging device is located above the qualified product conveying line 14 and the unqualified product conveying line 15 arranged in parallel. The injection-molded folding spoon products are grabbed by the robot and moved to the qualified product conveying line 14. A visual inspection system is installed above the qualified product conveying line 14. The folding spoon products passing under the visual inspection system undergo visual inspection to identify qualified and unqualified products. After the qualified products are transported by the sorting and arranging device, they are still transferred and transported along the qualified product conveying line 14 to the packaging equipment at the end. The unqualified products are transferred to the unqualified product conveying line 15 by the sorting and arranging device and transported to the unqualified product collection basket at the end of the line.

[0023] Its operating principle is: initially, the action parts of the two sorting and arranging components are located above the qualified product conveyor line 14, and the lifting box 4 descends and then rises and resets. During this process, the two sorting and arranging components absorb the front and rear folding spoon products that have been injection molded and completed visual inspection from the qualified product conveyor line 14. For qualified products, the sorting and arranging components perform the arranging operation (rotating the qualified products by a certain angle), and for unqualified products, the sorting and arranging components perform the sorting operation (shifting the unqualified products to the top of the unqualified product conveyor line 15). After that, the lifting box 4 descends and then rises and resets. During this process, the qualified products are placed back on the qualified product conveyor line 14 and the unqualified products are placed on the unqualified product conveyor line 15.

[0024] See Figure 2 and Figure 3 , we can see that:

[0025] The sorting and arranging assembly includes a transverse slide rail 5 and a slider 8 installed on the bottom wall of the lifting box 4, a transverse base plate 10 is installed on the slider 8, and a transverse cylinder 12 for driving the transverse base plate 10 to move reciprocatingly is installed on the bottom wall of the lifting box 4 through a support base 11.

[0026] The bottom wall of the lifting box 4 is provided with a longitudinally extending strip hole, within which a sorting and arranging rigid tube 6 is installed. A suction cup 9 is mounted at the lower end of the sorting and arranging rigid tube 6, and the upper end of the sorting and arranging rigid tube 6 is connected to a compressed air line via a rotary air joint 13. A rotary drive mechanism 7 is mounted on the transverse base plate 10, which drives the sorting and arranging rigid tube 6 in rotation.

[0027] The sorting action mode is: the suction cup 9 sucks up the unqualified products, the rotary drive mechanism 7 does not move, and the transverse cylinder 12 moves, so that the unqualified products are laterally shifted from above the qualified product conveyor line 14 to above the unqualified product conveyor line 15; the arranging action mode is: the suction cup 9 sucks up the qualified products, the rotary drive mechanism 7 moves, and the transverse cylinder 12 does not move, and the qualified products rotate a certain angle and are always located above the qualified product conveyor line 14.

[0028] See Figure 3 and Figure 4 , we can see that:

[0029] The rotary drive mechanism 7 comprises a rotary wheel with a central hole. The upper-middle portion of the sorting and arranging rigid tube 6 is positioned and fixed within the central hole of the rotary wheel. The rotary drive mechanism also includes a drive mechanism for driving the rotary wheel in forward and reverse rotation. In this embodiment, the rotary wheel is a rotary gear 7-11. An externally threaded portion is provided on the upper-middle portion of the sorting and arranging rigid tube 6. This externally threaded portion is positioned within the central hole of the rotary gear 7-11 and is fixedly connected to the rotary gear 7-11 using locking nuts located above and below the rotary gear 7-11, respectively. As a result, the sorting and arranging rigid tube 6 and the rotary gear 7-11 rotate synchronously.

[0030] The rotary drive mechanism 7 also includes a central base 7-3 with a groove at its top, within which a rotary gear 7-11 is positioned. A hollow shaft extending downward is located in the center of the rotary gear 7-11, which is located within an axial hole in the center of the central base 7-3. The drive mechanism drives the rotary gear 7-11 in both forward and reverse rotational directions. Due to the fit between the downwardly extending hollow shaft and the central base 7-3, the rotary gear 7-11 is capable of only rotary rotation.

[0031] The structure of the driving mechanism: The rotary driving mechanism 7 also includes a first end block 7-1 and a second end block 7-10 located on either side of the central base 7-3. A first sleeve 7-2 and a second cylinder 7-7 are installed between the first end block 7-1 and the central base 7-3. A second sleeve 7-9 and a first cylinder 7-12 are installed in opposite directions between the second end block 7-10 and the central base 7-3. That is, the first sleeve 7-2 and the first cylinder 7-12 are horizontally opposite each other, and the second sleeve 7-9 and the second cylinder 7-7 are horizontally opposite each other. A first piston 7-5 is installed in the first cylinder 7-12, and a first rack 7-4 is installed on the outside of the first piston 7-5. A second piston 7-6 is installed in the second cylinder 7-7, and a second rack 7-8 is installed on the outside of the second piston 7-6. The first rack 7-4 and the second rack 7-8 are respectively located on either side of the rotary gear 7-11 and are meshed with the rotary gear 7-11 for transmission.

[0032] The first cylinder 7-12 and the second cylinder 7-7 perform the inflation / exhaust operation at the same time. When inflating, the two pistons drive the two racks to move outward. At this time, the rotating gear 7-11 and the sorting arrangement hard tube 6 are in the Figure 4 The two racks rotate counterclockwise, and finally the ends of the two racks are located in the two sleeves respectively. At the same time, when exhausting, the two pistons drive the two racks to move inward. At this time, the rotating gears 7-11 and the sorting and arranging hard tube 6 are in the Figure 4 Rotate clockwise.

[0033] A solenoid valve is also provided inside the lifting box 4. Each lifting cylinder 2, transverse cylinder 12 and rotary drive mechanism 7 is connected to the compressed air pipeline and the exhaust pipeline through a solenoid valve. By controlling the action of each solenoid valve to control the on and off of the corresponding air path, the action control of the aforementioned starting components is realized.

[0034] Sorting and arranging operation mode:

[0035] The injection-molded folding spoon products are picked up by a robot and moved to the qualified product conveyor line 14. A visual inspection system is installed above the qualified product conveyor line 14. The folding spoon products passing under the visual inspection system undergo visual inspection to identify qualified and unqualified products.

[0036] Initially, the sorting and arranging tubes 6 of the two sorting and arranging assemblies and the suction cups 9 at their lower ends are located above the center line of the qualified product conveyor line 14. The lifting cylinder 2 is activated, and the lifting box 4 and its two sorting and arranging assemblies descend and then ascend to reset. During this process, the two sorting and arranging assemblies absorb the front and rear folding spoon products from the qualified product conveyor line 14.

[0037] For qualified products, the rotary drive mechanism 7 of the sorting and arranging assembly is activated, while the transverse cylinder 12 is inactive. The qualified products rotate a certain angle to adjust their posture, but are always located above the qualified product conveyor line 14. This is the arrangement operation. For unqualified products, the rotary drive mechanism 7 of the sorting and arranging assembly is inactive, while the transverse cylinder 12 is activated, and the unqualified products are laterally transferred from above the qualified product conveyor line 14 to above the unqualified product conveyor line 15.

[0038] After that, the lifting cylinder 2 is activated, and the lifting box 4 and its two sorting and arranging components descend and then rise and reset. During this process, qualified products are placed again on the qualified product conveyor line 14, and unqualified products are placed on the unqualified product conveyor line 15. That is, after the action of this sorting and arranging device, the qualified products are still transferred and transported along the qualified product conveyor line 14 to the packaging equipment at the end, and the unqualified products are transferred to the unqualified product conveyor line 15 by the action of this sorting and arranging device, and conveyed to the unqualified product collection basket at the end of the line; after resetting this step, the two sorting and arranging hard tubes 6 and the suction cups 9 at their lower ends are again located above the center line of the qualified product conveyor line 14, ready to perform the next sorting and arranging operation.
