Description

Technical Field

[0001] The present invention belongs to the technical field of bag unscrambling machines, and more specifically, relates to a material collecting and dropping component, a material collecting device and a bag unscrambling machine. Background Art

[0002] Packaging bags, especially plastic bags, provide numerous conveniences for daily life and work. Bag production typically occurs on a bag unscrambler, which stacks multiple bags together and secures them with rubber bands, creating bundles of bags. These bundles are then manually placed into packaging materials (woven bags or boxes) for easy storage and transportation.

[0003] Existing bag sorting machines include a material sorting device, a testing device, a material receiving device, and a packaging device. The material sorting device is used to sequentially convey individual packaging bags to the testing device. The testing device includes a detection mechanism and a waste discharge mechanism. The detection mechanism is used to inspect the packaging bags conveyed by the material sorting device and convey qualified packaging bags to the material receiving device. The waste discharge mechanism is used to remove unqualified packaging bags from the testing mechanism after inspection. The material receiving device is used to receive and stack multiple qualified packaging bags conveyed by the inspection mechanism, and then clamp the stacked packaging bags and place them in the packaging device. The packaging device is used to pack the stacked packaging bags. The material receiving device includes a material receiving movable module, a material receiving drop assembly, and a material receiving shielding member. The material receiving movable module is provided with a material receiving position, and the material receiving drop assembly is fixed to the movable part of the material receiving movable module. When the material receiving movable module drives the material receiving drop assembly to move to the material receiving position, the material receiving drop assembly is located below the material receiving shielding member, ensuring that a number of qualified packaging bags are transferred from the inspection mechanism to the material receiving device. Specifically, it ensures that a number of qualified packaging bags are transferred from the inspection transmission assembly to the material receiving drop assembly. The material receiving shielding member is used to block a number of qualified packaging bags delivered by the inspection mechanism and make the blocked qualified packaging bags fall into the material receiving drop assembly. The material receiving shielding member limits the horizontal movement of the packaging bags, and the packaging bags fall into the material receiving drop assembly under the action of gravity. However, the existing material receiving drop assembly is a trough structure, which is not conducive to sorting the multiple packaging bags stacked in the material receiving drop assembly.

DETAILED DESCRIPTION

[0042] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0043] like Figure 1 As shown, an embodiment of the present invention provides a bag sorting machine, which includes a material dividing device 1, a detection device 2, a material collecting device 3 and a packaging device 4.

[0044] The material dividing device 1 is used to sequentially convey individual packaging bags to the detection device 2 .

[0045] The detection device 2 includes a detection mechanism and a waste discharge mechanism. The detection mechanism is used to detect the packaging bags conveyed by the material separation device 1. The detection mechanism is also used to convey the packaging bags that have passed the inspection to the material receiving device 3. The waste discharge mechanism is used to remove the unqualified packaging bags after inspection from the detection mechanism.

[0046] The receiving device 3 is used to receive and stack the qualified packaging bags delivered by the inspection mechanism, and clamp the stacked packaging bags and place them in the packaging device 4.

[0047] The packing device 4 is used to pack a plurality of stacked packaging bags.

[0048] In one embodiment, if Figure 1 、 Figure 2 、 Figure 3 As shown, the inspection mechanism includes an inspection conveyor assembly, an inspection bracket 212, and an inspection assembly. The inspection assembly is mounted on the inspection bracket 212. The inspection conveyor assembly includes a first sub-conveying assembly 2111 and a second sub-conveying assembly 2112. The inspection bracket 212 spans the first sub-conveying assembly 2111. The inspection assembly is located above the first sub-conveying assembly 2111 and is used to inspect packaging bags transported on the first sub-conveying assembly 2111. A conveying gap 2113 is defined between the first sub-conveying assembly 2111 and the second sub-conveying assembly 2112. The inspection assembly includes a visual camera and an illumination device, which are fixed to the inspection bracket 212. The image capture end of the visual camera and the illumination end of the illumination device face the conveying surface of the first sub-conveying assembly 2111. The inspection mechanism also includes a visual processing center, and the visual camera and waste discharge mechanism are in communication with the visual processing center. Specifically, the visual processing center is in communication with the waste discharge drive mechanism 222. The visual camera sequentially captures real-time images of each packaging bag on the first sub-transmission component 2111, and sends each real-time image to the visual processing center. The visual processing center retrieves a pre-stored standard image and compares it with each real-time image in turn. If the current real-time image is different from the standard image, the packaging bag corresponding to the current real-time image is unqualified and generates unqualified data. The waste discharge mechanism is controlled to operate based on the unqualified data. In order to ensure that the unqualified packaging bag is removed from the transmission gap 2113 without affecting the adjacent packaging bags of the unqualified packaging bag on the inspection transmission component, the transmission spacing of each packaging bag on the inspection transmission component is reasonably set, and the parameters such as the working time and working speed of the waste discharge mechanism are also reasonably set.

[0049] In one embodiment, if Figure 1 、 Figure 2 、 Figure 3As shown, the waste discharge mechanism includes a waste discharge bracket 221, a waste discharge drive mechanism 222, a waste discharge baffle 223, and a waste discharge air blowing device. The waste discharge bracket 221 spans the inspection conveyor assembly, and the fixed portion 2231 of the waste discharge drive mechanism 222 is fixed to the waste discharge bracket 221. The waste discharge drive mechanism 222 and the waste discharge baffle 223 are located above the conveying gap 2113. The waste discharge baffle 223 includes a fixed portion 2231 and a guide portion 2232 connected to the fixed portion 2231. The fixed portion 2231 of the waste discharge baffle 223 is fixed to the output shaft of the waste discharge drive mechanism 222. Preferably, the fixed portion 2231 and the guide portion 2232 are integrally formed. The guide portion 2232 is configured to contact unqualified packaging bags to direct them downward toward the conveying gap 2113, ensuring that the unqualified packaging bags move downward toward the conveying gap 2113. The waste discharge baffle 223 is provided with an air blowing hole, which passes through the waste discharge baffle 223. Preferably, one end of the air blowing hole is located on the fixing portion 2231, and the other end of the air blowing hole is located on the guide portion 2232; or the air blowing hole passes through the guide portion 2232. The waste discharge air blowing device includes an air pump and an air pipe. The air pump is arranged outside the detection mechanism and is not in contact with the material dividing device 1, the material receiving device 3 and the packaging device 4. One end of the air pipe is connected to the air pump and communicated with the air outlet end of the air pump, and the other end of the air pipe faces the air blowing hole. The air pump uses the air pipe to quickly move the packaging bag in contact with the waste discharge baffle 223 to the bottom of the conveying gap 2113. Preferably, the air pump is fixed on the waste discharge bracket 221. The air pipe is a rigid pipe or a flexible pipe. When the air pipe is a rigid tube, the air pump is fixed to the waste discharge bracket 221. One end of the rigid tube is fixed to the air pump and connected to the air pump's outlet. The other end of the rigid tube is located on one side of the fixing portion 2231 and faces the air blowing hole. The air pump blows air into the air blowing hole through the rigid tube. When the air pipe is a flexible tube, one end of the flexible tube is connected to the air pump's outlet. The other end of the flexible tube is connected to the air blowing hole and fixed to the waste discharge baffle 223. The air pump blows air into the air blowing hole through the flexible tube without affecting the movement of the waste discharge drive mechanism 222 in driving the waste discharge baffle 223. The waste discharge baffle 223 is an arc-shaped plate or a V-shaped plate. The waste discharge drive mechanism 222 is an exhaust cylinder or a waste discharge linear motor.

[0050] In one embodiment, if Figure 1 、 Figure 2 、 Figure 3As shown, to further reduce friction between the guide portion 2232 and the packaging bags, the waste discharge mechanism also includes a waste discharge roller 224, which is rotatably connected to the waste discharge baffle 223. The waste discharge roller 224 is located on the fixed portion 2231 of the waste discharge baffle 223 and is located on one side of the guide portion 2232. Unqualified packaging bags first contact the waste discharge roller 224 and then the guide portion 2232, reducing friction between the unqualified packaging bags and the waste discharge baffle 223. This ensures that unqualified packaging bags move toward and below the conveying gap 2113, ensuring that they are discharged from the inspection mechanism. The waste discharge mechanism also includes two opposing waste discharge connecting plates 225, which are fixed to the fixed portion 2231. Preferably, the waste discharge connecting plates 225 are integrally formed with the waste discharge baffle 223. The two ends of the waste discharge roller 224 are rotatably connected to two waste row connecting plates 225 respectively, and the waste discharge connecting plates 225 improve the stability and convenience of the waste discharge roller 224 being connected to the waste discharge baffle 223.

[0051] In one embodiment, if Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown, the receiving device 3 includes a receiving movable module 31, a receiving drop assembly 32, and a receiving shielding member 33. The receiving movable module 31 is provided with a receiving position 311. The receiving drop assembly 32 is fixed to the movable portion of the receiving movable module 31. When the receiving movable module 31 drives the receiving drop assembly 32 to move to the receiving position 311, the receiving drop assembly 32 is located below the receiving shielding member 33, ensuring that a number of qualified packaging bags are transferred from the inspection mechanism to the receiving device 3. Specifically, it ensures that a number of qualified packaging bags are transferred from the inspection and conveying assembly to the receiving drop assembly 32. The receiving block 33 is used to block the qualified packaging bags conveyed by the inspection mechanism and cause them to fall into the receiving and dropping assembly 32. The receiving block 33 restricts the horizontal movement of the packaging bags, causing them to fall into the receiving and dropping assembly 32 under the action of gravity. Preferably, the receiving block 33 is located at the end of the second sub-conveyor assembly 2112 away from the first sub-conveyor assembly 2111. A drop gap 331 is formed between the receiving block 33 and the end of the second sub-conveyor assembly 2112. The drop gap 331 is used to allow the blocked qualified packaging bags to fall into the receiving and dropping assembly 32. The drop gap 331 is appropriately set according to the size of the packaging bags. Preferably, the receiving movable module 31 is a servo motor module or a cylinder module.

The receiving seat 323 is disposed on the movable portion of the receiving movable module 31, and the first receiving support 324 is disposed on the receiving seat 323. The receiving seat 323, the first receiving support, the first receiving member 321, and the second receiving member 322 cooperate to support the packaging bags. The arrangement between the first and second receiving members 321 and 322 facilitates the arrangement of the stacked multiple packaging bags within the receiving and dropping assembly 32.

A packaging bag typically has a first portion and a second portion, the first portion being thicker than the second portion. When a certain number of packaging bags are stacked, if all the packaging bags are oriented in the same direction, the stacked plurality of packaging bags will have a local thickness relative to the thickness of the rest of the stacked bag, making the stacked bag more likely to fall apart during packaging. In response to the above problem, when stacking a certain number of packaging bags, the material receiving rotating drive member 34 is first used to drive the material receiving seat 323 to drive the material receiving and dropping assembly 32 to rotate to the first rotation state, and a part of the packaging bags are stacked in the material receiving and dropping assembly 32 in the first rotation state, and then the material receiving rotating drive member 34 is used to drive the material receiving seat 323 to drive the material receiving and dropping assembly 32 to rotate to the second rotation state, and the remaining packaging bags are stacked in the material receiving and dropping assembly 32 in the second rotation state. The direction of the packaging bags stacked in the material receiving and dropping assembly 32 in the first rotation state is different from the direction of the packaging bags stacked in the material receiving and dropping assembly 32 in the second rotation state, which is conducive to stacking a certain number of packaging bags to form a whole with similar local thickness.

The second connecting pin 329 is disposed through the second material receiving support 327 and cooperates with the material receiving seat 323 to clamp the second material receiving support 327. More preferably, the first connecting pin 328 and the second connecting pin 329 are threadedly connected to the adjustment hole 3231. The connection structure between the first connecting pin 328 and the second connecting pin 329 and the adjustment hole 3231 is simple and very practical.

[0066] In one embodiment, if Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown, when the aligning plate 352 is rotatably connected to the aligning bracket 351, the receiving and aligning mechanism 35 is disposed on one side of the aligning plate 352.

[0068] In one embodiment, if Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown, to facilitate the removal of stacked packaging bags from the receiving and dropping assembly 32, the receiving device 3 further includes a receiving mechanical claw assembly 36. The receiving movable module 31 is provided with a clamping position 312. The receiving movable module 31 drives the receiving and dropping assembly 32 to repeatedly move between the receiving position 311 and the clamping position 312. When the receiving and dropping assembly 32 is at the clamping position 312, the receiving mechanical claw assembly 36 removes the stacked packaging bags from the receiving and dropping assembly 32.

[0069] In one embodiment, if Figure 1 、 Figure 7 、 Figure 8 and Figure 9 As shown, the packaging device 4 includes a packaging frame 41, a packaging jaw assembly 42, and a packaging drive assembly 43. The fixed portion 2231 of the packaging drive assembly 43 is fixed to the packaging frame 41, while the fixed portion 2231 of the packaging jaw assembly 42 is fixed to the movable portion of the packaging drive assembly 43. The packaging drive assembly 43 has a first packaging position and a second packaging position. When the packaging drive assembly 43 transports the packaging jaw assembly 42 to the first packaging position, the packaging jaw assembly 42 clamps the packaging bags on the receiving mechanical claw assembly 36. When the packaging drive assembly 43 transports the packaging jaw assembly 42 to the second packaging position, the user can tie the packaging bags on the packaging jaw assembly 42. To enhance the convenience of tie-tying, the packaging device 4 also includes a tie-tying machine 44. When the packaging drive assembly 43 transports the packaging jaw assembly 42 to the second packaging position, the tie-tying machine 44 is used to tie the packaging bags on the packaging jaw assembly 42.

The packing claw module 422 includes a packing fixed seat 4221, a packing rotation drive mechanism 4222, a packing transmission assembly 4223 and a packing claw rod 4224. The packing fixed seat 4221 is detachably connected to the claw mounting seat, and the packing rotation drive mechanism 4222 is arranged on the packing fixed seat 4221; one end of the packing claw rod 4224 is rotatably connected to the packing fixed seat 4221, and the end of the packing claw rod 4224 away from the packing fixed seat 4221 and the lower side of the packing claw mounting seat 421 form a packing clamping space 4211; one end of the packing transmission assembly 4223 is connected to the movable part of the packing rotation drive mechanism 4222, and the other end of the packing transmission assembly 4223 is connected to the packing claw rod 4224, and the packing transmission assembly 4223 drives the packing claw rod 4224 to rotate through the packing transmission assembly 4223. When the stacked multiple packaging bags are clamped in the packaging clamping space 4211, the packaging claw rod 4224 plays a major role in bearing the force, the packaging rotation drive mechanism 4222 is subjected to less force, and the packaging rotation drive mechanism is not easily damaged. Preferably, the packaging transmission assembly 4223 includes a first packaging gear 42231, a second packaging gear 42232 and a packaging conveyor toothed belt 42233, the first packaging gear 42231 is fixed to the movable part of the rotation drive mechanism and is coaxially connected to the movable part of the rotation drive mechanism, the second packaging gear 42232 is fixed to the packaging claw rod 4224, the rotation axis of the second packaging gear 42232 is coaxially arranged with the rotation axis of the packaging claw rod 4224, the packaging conveyor toothed belt 42233 is wound around the first packaging gear 42231 and the second packaging gear 42232, and the first packaging gear 42231 and the second packaging gear 42232 are meshed with the packaging conveyor toothed belt 42233. To protect the multiple stacked packaging bags within the packaging clamping space 4211, the packaging clamping module 422 also includes an elastic protective member 4225 secured to the packaging clamping rod 4224. This prevents the packaging clamping rod 4224 from directly contacting the multiple stacked packaging bags within the packaging clamping space 4211, thereby minimizing damage to the bags. When the end of the packaging clamping rod 4224, distal from the packaging fixing seat 4221, forms the packaging clamping space 4211 with the underside of the packaging clamping seat 421, the elastic protective member 4225 is located within the packaging clamping space 4211. Preferably, the packaging rotation drive mechanism 4222 is a packaging motor.

[0071] In one embodiment, if Figure 1 、 Figure 7 、 Figure 8 and Figure 9 As shown, in order to reduce the overall length of the packaging device 4 and reduce the cost of the packaging drive assembly 43, the packaging drive assembly 43 includes at least two packaging cylinder drive modules 431. All packaging cylinder drive modules 431 are arranged along the horizontal direction, which is the X direction or the Y direction. All packaging cylinder drive modules 431 are arranged in parallel and connected in sequence. Among all packaging cylinder drive modules 431: the fixed portion 2231 of one packaging cylinder drive module 431 is fixed to the packaging frame 41, and the movable portion of another packaging cylinder drive module 431 is fixed to the fixed portion 2231 of the packaging clamping claw assembly 42.
