Description

Technical Field

[0001] This invention belongs to the field of medical dressing packaging technology, and specifically relates to a material collection and flipping palletizing system between a bagging machine and a packaging machine, and its operation method. Background Technology

[0002] Chinese patent document CN202210653702.4 discloses an automatic gauze sheet packaging machine and method. The automatic gauze sheet packaging machine is used to package gauze sheets produced by a high-folding machine. The packaged and stacked products have a cuboid structure (square wrapping paper + gauze sheet). These stacked products need to be stacked and then bagged, thus packaging individual stacked products into larger stacked packages for easier transportation and wholesale. The current technical problem is: 1. There is a lack of connection between the packaging machine and the bagging machine. Currently, it is necessary to manually transfer the products to the bagging machine for palletizing and bagging. 2. The entry height of the bagging machine is fixed (the bagging machine is a fixed model). If the products to be stacked are stacked upwards, a maximum of four layers can be arranged, and it cannot match the packaging box specifications. Therefore, the stacking method needs to be improved and the traditional stacking method cannot be used. Summary of the Invention

[0003] In view of the technical problems existing in the background technology, the present invention provides a material collection and flipping palletizing system and its operation method between a bagging machine and a packaging machine. The products exported from the packaging machine can be directly arranged and transported to the flipping palletizing device. The traditional palletizing method is changed to a flipping palletizing method. The height of the stacking array is the length of the product being stacked. The length of the stack is determined by the number of rows of the stack. The number of rows can be freely set according to the process, so that the stacking array can be adapted to the existing bagging machine specifications.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A material collection and palletizing system between a bagging machine and a packaging machine includes a leveling device, the output end of which is connected to the input end of a material collection device. The output end of the material collection device is equipped with a palletizing device. The palletizing device includes a first pushing mechanism and a second pushing mechanism. The first pushing mechanism is used to work on a first platform, and the second pushing mechanism is used to work on a second platform. The second platform is lower than the first platform, and the first platform and the second platform are stepped. A baffle mechanism is provided on the second platform.

[0005] Preferably, the baffle mechanism includes a blocking baffle, which is driven by a cylinder to move up and down.

[0006] Preferably, the sizing device includes a sizing conveyor with a sizing baffle above it; the collecting device includes a collecting conveyor with a collecting baffle above it; the collecting conveyor and the sizing conveyor are perpendicular to each other in their conveying directions.

[0007] Preferably, a transfer pusher mechanism is provided between the sizing conveyor and the collecting conveyor, which is used to push the palletized products on the sizing conveyor onto the collecting conveyor.

[0008] Preferably, the second platform is provided with a bagging machine feeding pusher device on its side. The bagging machine feeding pusher device includes an electric screw drive device, which is used to drive the lateral telescopic device to move back and forth. The lateral telescopic device is used to drive the feeding pusher to extend and retract. The feeding pusher is used to cooperate with the second pushing mechanism.

[0009] Preferably, the operation method of the material collection and flipping palletizing system between the bagging machine and the packaging machine includes the following steps: Step 1: The stacked products are transported to the collection conveyor side using the sizing device's sizing conveyor. The sizing baffle is used to adjust the angle of the stacked products to be perpendicular to the conveying direction of the collection conveyor. Step two: The palletized products are pushed onto the collection conveyor using a transfer and pusher mechanism. The collection conveyor and collection baffles are used to arrange the multiple palletized products into a tight fit. The collection conveyor then transports the palletized products to the first platform. Step 3: Use the first push mechanism to push a row of products from the first platform toward the second platform. The push mechanism stops after pushing the center of gravity of the products out of the area where the first platform is located. Step four: The product rotates for the first time due to the loss of its own center of gravity; Step 5: The first pushing mechanism is restarted, and the baffle of the baffle mechanism is in a low position. The first pushing mechanism continues to push the product forward. The first pushing mechanism, together with the baffle mechanism, rotates the product a second time, so that the product is in an upright position; the first pushing mechanism is reset. Step six: The baffle of the baffle mechanism rises to the high position, and the feeding push plate of the bagging machine feeding push plate device moves to the product. The feeding push plate cooperates with the feeding push plate to clamp the product. The second pushing mechanism and the feeding push plate move synchronously to push the product forward for the width of one row of products and then stop. During the above process, the feeding push plate is in low-speed operation mode. Step 7: The second pushing mechanism is reset, and the above actions are repeated to flip and stack multiple rows of products. Step 8: After the specified array of stacking is completed, the bagging machine feed pusher device is activated, the lateral telescopic device drives the feed pusher to retract, the electric screw drive device drives the lateral telescopic device and the feed pusher to move to the other side of the array, and the lateral telescopic device is activated again to drive the feed pusher to extend. Step nine: The electric screw drive device is started and put into fast operation mode, pushing the entire stack to the bagging machine for bagging operation.

[0010] This patent can achieve the following beneficial effects: In this invention, the exported products of the packaging machine can be directly sorted and transported to the flip-type palletizing device. After the flip-type palletizing device performs the palletizing operation, the stack is pushed to the bagging machine for bagging. The entire system realizes automated transfer and saves manpower for manual handling.

[0011] This invention replaces the traditional palletizing method with a flip-type palletizing method. The height of the stacking array is the length of the product being palletized, and the length of the stack is determined by the number of rows. The number of rows can be freely set according to the process, allowing the stacking array to be adapted to existing bagging machine specifications. For example, this invention can perform "5×8" specification (8 rows, 5 columns) palletizing, thus solving the drawbacks of the stacking palletizing method. Attached Figure Description

[0013] Preferred solutions include Figures 1 to 10 As shown, a material collection and palletizing system and its operation method between a bagging machine and a packaging machine include a leveling device 1, the output end of which is connected to the input end of a material collection device 2. The output end of the material collection device 2 is equipped with a palletizing device 3. The palletizing device 3 includes a first pushing mechanism 301 and a second pushing mechanism 302. The first pushing mechanism 301 operates on a first platform 303, and the second pushing mechanism 302 operates on a second platform 304. The second platform 304 is lower than the first platform 303, and the two platforms are stepped. A baffle mechanism 305 is provided on the second platform 304. In this embodiment, the product to be palletized is a gauze sheet bagged by the packaging machine. This product has a cuboid structure with a square cross-section. The product to be palletized on the first platform 303 is transported by the material collection conveyor of the material collection device or pushed by the pusher mechanism. Figure 2 As shown, the palletized product is currently placed flat on the first platform 303. The first pushing mechanism 301 pushes the palletized product towards the second platform 304. When the center of gravity of the palletized product exceeds the first platform 303, the product undergoes its first rotation, the effect of which is as follows: Figure 3 As shown; then the first pushing mechanism 301 continues to push forward, cooperating with the baffle mechanism 305 to perform a second rotation on the palletized product, so that the palletized product is in an upright state, the effect of which is as follows. Figure 4 As shown; then the second pushing mechanism 302 moves, pushing the palletized product to the right. At this time, the blocking baffle of the baffle mechanism 305 rises, and its effect is as follows. Figure 5 As shown. By repeating the above actions, multiple rows of palletized products will be flipped and stacked.

[0014] Specifically, the baffle mechanism 305 includes a blocking baffle, which is driven to move up and down by a cylinder. Furthermore, in this embodiment, both the first pushing mechanism 301 and the second pushing mechanism 302 employ a cylinder and pusher plate structure.

[0015] Preferably, the sizing device 1 includes a sizing conveyor 101, with a sizing baffle 102 above it; the collecting device 2 includes a collecting conveyor 201, with a collecting baffle 202 above it; the conveying directions of the collecting conveyor 201 and the sizing conveyor 101 are perpendicular to each other. The sizing conveyor 101 and the collecting conveyor 201 can be belt conveyors or belt-type conveyors.

[0016] Preferably, a transfer pusher mechanism 4 is provided between the sizing conveyor 101 and the collecting conveyor 201. The transfer pusher mechanism 4 is used to push the stacked products 5 on the sizing conveyor 101 onto the collecting conveyor 201. A device similar to the transfer pusher mechanism 4 can also be added between the collecting conveyor 201 and the first platform 303. The transfer pusher mechanism 4 consists of two cylinders and a pusher plate. One cylinder is used to drive the pusher plate to move up and down, and the other cylinder is used to drive the pusher plate to move left and right.

[0017] Preferably, the second platform 304 is provided with a bagging machine feeding pusher device on its side. The bagging machine feeding pusher device includes an electric screw drive device 306, which drives the lateral telescopic device 307 to reciprocate. The lateral telescopic device 307 drives the feeding pusher 308 to extend and retract. The feeding pusher 308 cooperates with the second pushing mechanism 302. The bagging machine feeding pusher device has two functions: first, it moves together with the second pushing mechanism 302 to prevent the stacked products from tipping over during the stacking process; second, after the stacking is completed (for example, after completing a "5×8" stacking operation), the feeding pusher 308 is driven to the other side of the stack, and then the entire stack is quickly pushed to the bagging machine.

[0018] The electric lead screw drive device 306 includes a motor, a lead screw, and a track. The lead screw is threadedly engaged with the lateral telescopic device 307, which facilitates the large-span movement of the lateral telescopic device 307. The lateral telescopic device 307 includes a slider, a cylinder, and a feed push plate 308. The slider is threadedly engaged with the lead screw, and the cylinder and the feed push plate 308 are mounted on the slider.

[0019] Preferably, the operation method of the material collection and flipping palletizing system between the bagging machine and the packaging machine includes the following steps: Step 1: The stacked product 5 is transported to the collection conveyor 201 side by the straightening conveyor 101 of the straightening device 1. The straightening baffle 102 is used to adjust the angle of the stacked product 5 to be perpendicular to the conveying direction of the collection conveyor 201. Step 2: The palletized products 5 are pushed onto the collection conveyor 201 using the transfer pusher mechanism 4. The collection conveyor 201 and the collection baffle 202 are used to arrange the multiple palletized products 5 into a tight fit. The collection conveyor 201 transports the palletized products 5 onto the first platform 303. Step 3, as Figure 2 As shown, the first push mechanism 301 pushes a row of products on the first platform 303 toward the second platform 304. The first push mechanism 301 stops after pushing the center of gravity of the products out of the area where the first platform 303 is located. Step four, as Figure 3 As shown, the product rotates for the first time due to the loss of its center of gravity. Step 5, as Figure 4 As shown, the first pushing mechanism 301 is restarted, and the blocking baffle of the baffle mechanism 305 is in a low position. The first pushing mechanism 301 continues to push the product forward. The first pushing mechanism 301, in conjunction with the baffle mechanism 305, rotates the product a second time, so that the product is in an upright state. The first pushing mechanism 301 is then reset. Step six, as Figure 5-6 As shown, the baffle of the baffle mechanism 305 rises to the high position, and the feeding push plate 308 of the bagging machine feeding push plate device moves to the product position. The feeding push plate 308 cooperates with the feeding push plate 308 to clamp the product. The second pushing mechanism 302 and the feeding push plate 308 move synchronously to push the product forward for a distance equal to the width of a row of products and then stop. During the above process, the feeding push plate 308 is in low-speed operation mode. Step seven, as Figure 7 As shown, the second pushing mechanism 302 resets, and the above actions are repeated to flip and stack multiple rows of products. Step eight, as Figure 8 As shown, when the specified square array is completed, the bagging machine feed pusher device is activated, the lateral telescopic device 307 drives the feed pusher 308 to retract, the electric screw drive device 306 drives the lateral telescopic device 307 and the feed pusher 308 to move to the other side of the square array, and the lateral telescopic device 307 is activated again to drive the feed pusher 308 to extend. Step nine, as Figure 9 As shown, the electric screw drive device 306 starts and enters the fast operation mode, pushing the entire stack to the bagging machine for bagging operation.

The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
