Description

Technical Field

[0001] The utility model relates to the technical field of product blanking and handling, in particular to an NG blanking device. Background Art

[0002] In the production line of the manufacturing industry, the product inspection link is crucial for ensuring product quality and meeting customer requirements. Once the product inspection is completed, qualified products and unqualified products need to be processed for blanking respectively to ensure the smooth operation of the production line and the efficient classification of products. However, in the process of blanking treatment of unqualified products, the existing technologies have obvious limitations.

[0003] At present, for the blanking treatment of unqualified products, the common practice is to use a manipulator to transport the products to the blanking conveyor line one by one. Although this method realizes the automatic handling of products, it faces many problems in practical applications. First of all, since the manipulator usually only responsible for handling a single product and cannot stack unqualified products, which greatly limits its application in scenarios where stacking and palletizing are required. Secondly, when unqualified products need to be transported to a far-away workstation or workshop for further processing, the traditional conveyor line often cannot meet this requirement due to the limitations of length and flexibility; for this reason, we provide an NG blanking device to solve the above problems.

[0032] As Figure 1 — Figure 9 shown in the embodiment.

[0033] An NG blanking device includes a first lifting structure 1 for loading empty pallets. Above the first lifting structure 1, there is a first handling structure 2 for handling empty pallets. Below the handling path of the first handling structure 2, there is a transfer structure 3. Below the transfer structure 3, there is a conveyor line structure 6. Between the feeding end of the conveyor line structure 6 and the transfer structure 3, there is a second lifting structure 5. Between the second lifting structure 5 and the transfer structure 3, there is a second handling structure 4 for handling the pallet with unqualified products to the second lifting structure 5. It also includes a blanking handling structure 9 for handling unqualified products to the transfer structure 3.

[0034] Refer to Figure 1 and Figure 2 As shown, when it is necessary to cut the unqualified products, first, the cutting and handling structure 9 transports the unqualified products after upstream inspection to the cutting position. At the same time, the first lifting structure 1 lifts the empty tray at its loading position to the loading position of the first handling structure 2. At this time, the transfer structure 3 moves to the unloading position of the first handling structure 2. Next, the first handling structure 2 transports the empty tray at the loading position to the transfer structure 3. Then, the transfer structure 3 drives the empty tray to move to the unloading position of the cutting and handling structure 9. The cutting and handling structure 9 transports the unqualified products to the empty tray on the transfer structure 3. Subsequently, the transfer structure 3 drives the tray loaded with unqualified products to move to the loading position of the second handling structure 4. The second handling structure 4 transports the tray loaded with unqualified products to the second lifting structure 5. As the subsequent handling of the trays loaded with unqualified products continues, the second lifting structure 5 gradually descends to stack the trays loaded with unqualified products. When the trays loaded with unqualified products on the second lifting structure 5 are stacked to a certain number, the stacked trays are transported to the conveyor line structure 6. The conveyor line structure 6 can transport the stacked trays to a predetermined position and can also buffer on the conveyor line structure 6, that is, there are multiple stacks of trays loaded with unqualified products buffered on the conveyor line structure 6. After buffering a certain number, it can cooperate with manual labor to transfer the multiple stacks of trays loaded with unqualified products stacked inside, or transfer the tray closest to the exit. Since buffering can be carried out in the conveyor line structure 6, it is not necessary to frequently transfer the stacked trays, reducing the labor intensity.

[0035] Here, manual transfer can be carried out by using a trolley to transport multiple stacked trays onto it for transfer, or it can be automatically connected by an AGV cart. Here, other types can also be adopted for the method of transferring the stacked trays on the conveyor line structure 6, which is not specifically limited here.

[0036] It should be noted that the cutting and handling structure 9 can cut both unqualified products and qualified products, which is not limited here. Correspondingly, a corresponding belt line can also be set on the moving path of the cutting and handling structure 9 to cut the qualified products. The qualified products are transported to the next process through the belt line. The specific position where the belt line is set is not limited here and is set according to actual needs in practice.

[0037] The first lifting structure 1 includes a vertical plate 11. A lifting linear module 12 is fixedly installed on the side of the vertical plate 11. A fork 13 for carrying the tray is installed at the lifting end of the lifting linear module 12.

[0038] Refer to Figure 3As shown, the tooth fork 13 is driven to rise by the lifting linear module 12, so as to gradually load the empty pallets on the tooth fork 13, that is, every time the top empty pallet is transported by the first transport structure 2, it rises to the height of a pallet, and the empty pallets are loaded reciprocally in this way until the empty pallets on the tooth fork 13 are loaded, and then the tooth fork 13 returns to its initial position, that is, the bottom, waiting for the next group of empty pallets to be placed on the tooth fork 13.

[0039] In this embodiment, the structure of the second lifting structure 5 is the same as that of the first lifting structure 1. The difference is that the second lifting structure 5 gradually takes over the pallets containing unqualified products from the second transport structure 4, and descends one pallet height after taking over each pallet, until the second lifting structure 5 takes over a certain number of pallets and transports the stacked pallets to the conveyor line structure 6, completing the stacking and transport of the pallets.

[0040] The first transport structure 2 includes a gantry 21, a transverse linear module 22 is fixedly installed on the side of the gantry 21, a first lifting cylinder 23 is fixedly installed on the moving end of the transverse linear module 22, a first mounting frame 24 is fixedly installed on the lifting end of the first lifting cylinder 23, and a plurality of first suction cups 25 whose shape matches the shape of the pallet are installed on the first mounting frame 24.

[0041] See also Figure 4 As shown, when transportation is required, the first suction cup 25 is first moved to the top of the first lifting structure 1 through the transverse linear module 22, and the first lifting cylinder 23 drives the first suction cup 25 to contact and adsorb the empty pallet on the first lifting structure 1. Next, the empty pallet adsorbed by the first suction cup 25 is transported to the transfer structure 3 under the linkage of the transverse linear module 22 and the first lifting cylinder 23, thereby completing the transportation of the empty pallet.

[0042] The transfer structure 3 includes a guide rail 31 and a transfer linear module 32 . A carrier plate 33 for carrying a tray is fixedly mounted on the movable end of the transfer linear module 32 , and the carrier plate 33 is slidably mounted on the guide rail 31 .

[0043] A plurality of limit blocks 34 are fixedly mounted on the upper surface of the carrier plate 33 , and a shape formed by the plurality of limit blocks 34 matches the shape of the tray; a sensor 35 is mounted in a groove on the upper surface of the carrier plate 33 .

[0044] See also Figure 5 and Figure 6As shown, the transfer linear module 32 drives the carrier plate 33 to move, and the tray is limited on the carrier plate 33 through the limitation of the first mounting bracket 24 to prevent the tray from moving during transfer. Moreover, the sensor 35 detects whether there is a tray on the carrier plate 33 to determine whether the tray is placed on the carrier plate 33 or removed from it.

[0045] The second handling structure 4 includes a fixed frame 41. A second lifting cylinder 42 is fixedly installed on the side plate of the fixed frame 41. The lifting end of the second lifting cylinder 42 is equipped with a second mounting bracket 43, and a plurality of second suction cups 44 whose combined shape matches the shape of the tray are installed on the second mounting bracket 43.

[0046] Refer to Figure 7 As shown, first, the second lifting cylinder 42 drives the second suction cups 44 to descend and adsorb the tray on the carrier plate 33. Then, the second lifting cylinder 42 drives the tray adsorbed by the second suction cups 44 to lift off the carrier plate 33. Next, the transfer linear module 32 drives the carrier plate 33 to return to the initial position. Then, the second lifting cylinder 42 drives the second suction cups 44 to adsorb the tray containing unqualified products and descend to the second lifting structure 5. The second lifting structure 5 carries and stacks the trays conveyed by the second handling structure 4. After each tray is carried, it descends by the height of one tray to facilitate receiving the next tray containing unqualified products.

[0047] The conveyor line structure 6 includes a chassis 61. A conveyor line body 62 is installed on the chassis 61. A support plate 63 for supporting the conveyor line body 62 is also installed on the chassis 61. A plurality of baffles 64 are fixedly installed on both side frames of the chassis 61.

[0048] Refer to Figure 8 As shown, a support plate 63 is arranged below the conveyor line body 62 to be able to carry the stacked trays conveyed by the conveyor line body 62, enabling it to carry a certain number of trays. And to facilitate the second lifting structure 5 to carry the stacked trays onto the conveyor line body 62 for conveyance, the width of the conveyor line body 62 is smaller than the width of the fork 13 in the second lifting structure 5, that is, the load-bearing rods of the fork 13 are located on both sides of the conveyor line body 62, thus facilitating the fork 13 to avoid the conveyor line body 62. After the fork 13 is located below the conveyor line body 62, the conveyor line body 62 then carries and conveys the stacked trays to complete the handling. Moreover, to prevent the trays from moving during conveyance, they are guided by the baffles 64 on both sides to enable smooth conveyance.

[0049] The blanking and handling structure 9 includes a two-axis moving module 91. A connecting frame 92 is installed on the moving end of the two-axis moving module 91. A rotating motor 93 is fixedly installed on the connecting frame 92. A third mounting frame 94 is fixedly installed on the rotating end of the rotating motor 93. A plurality of third suction cups 95 for adsorbing products are installed on the third mounting frame 94.

[0050] Refer to Figure 9 As shown, when it is necessary to handle the unqualified products detected upstream, first, the third suction cup 95 is moved to the position of the unqualified product and adsorbed through the linkage of the two-axis moving module 91 and the rotating motor 93. Then, it is transported to the carrier plate 33 at the blanking position through the linkage of the two-axis moving module 91 and the rotating motor 93 to complete blanking. Here, the rotation of the rotating motor 93 can load and unload products at different angles.

[0051] It should be noted here that the two-axis moving module 91 can move in two directions of horizontal and vertical. Specifically, this function can be realized by combining two motor screw linear modules, or other linear module combinations can also be used, such as motor synchronous belt modules, cylinders and other linear drive components. Specifically, it is not limited here.

[0052] A carrier table 7 is arranged below the loading position of the first lifting structure 1. An avoidance groove 8 adapted to the tooth fork 13 is opened on the carrier table 7.

[0053] Through the cooperation of the carrier table 7 and the avoidance groove 8, the stacked empty pallets can be placed on the carrier table 7. Driven by the vertical plate 11, the tooth fork 13 moves upward in the avoidance groove 8 to lift and load the stacked empty pallets on the carrier table 7, eliminating the need for manual placement of the stacked empty pallets on the tooth fork 13 and automatically realizing lifting.

[0054] The working process of the present utility model is as follows: First, the blanking and handling structure 9 transports the unqualified products detected upstream to the blanking position. At the same time, the first lifting structure 1 transports the empty pallets to the loading position of the first handling structure 2. The first handling structure 2 transports the empty pallets at the loading position to the transfer structure 3. The transfer structure 3 transports the empty pallets to the blanking position of the blanking and handling structure 9 to receive the unqualified products from the blanking and handling structure 9. After the empty pallets on the transfer structure 3 are loaded with unqualified products, they are moved to the position of the second handling structure 4. The second handling structure 4 adsorbs and transports the pallets to be stacked on the second lifting structure 5. After a certain number of pallets are stacked on the second lifting structure 5, they are transported to the conveyor line structure 6, and the conveyor line structure 6 caches or transports out the stacked pallets loaded with unqualified products.

[0055] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
