Description

Technical Field

[0001] The utility model relates to the field of automation, in particular to an adjustment module of a thin plate packaging box and automatic feeding equipment. Background Art

[0002] Thin sheet packaging boxes are die-cut from cardboard and then folded and glued together for use. When packaging a large number of boxes, after die-cutting, they are typically stacked in specific quantities and placed on pallets for storage and transport.

[0003] When packaging boxes are used, they need to be fed one by one in piles. Sorting and transferring the piles is tedious and labor-intensive, making automation difficult. Furthermore, during the palletizing process, adjacent layers of the piles may have different orientations, requiring posture adjustments during the feeding process, further increasing the complexity. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide an adjustment module for a thin plate packaging box and an automatic feeding device, which can automatically complete the posture adjustment operation of the material pile and has the advantage of a high degree of automation.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an adjustment module for a thin plate packaging box, comprising a horizontal flip assembly and a longitudinal flip assembly, wherein the horizontal flip assembly comprises a support clamp and a horizontal flip drive mechanism, wherein the support clamp comprises two support arms, the two support arms being arranged in parallel in a vertical direction, and support plates being provided on the inner sides of the two support arms, respectively, and the horizontal flip drive mechanism is used to drive the support arms to move up and down, and to rotate about a vertical center line;

[0006] The longitudinal flip assembly includes a flip frame and a longitudinal flip drive mechanism. The longitudinal flip drive mechanism is used to drive the flip frame to rotate, and the rotation center line is located in the horizontal plane and is arranged perpendicular to the conveying direction of the conveying assembly; the flip frame has at least two position states. In the first position state and the second position state, the opening of the flip frame is horizontally arranged, and the opening faces different directions.

[0007] During horizontal flipping, the pile is fed between the two supporting arms, and the lifting drive drives the supporting clamp and the pile to rise synchronously. The horizontal flip drive mechanism then drives the supporting clamp and the pile to rotate synchronously horizontally, achieving horizontal adjustment of the pile's posture. During longitudinal flipping, the flip frame is first in the first position, and the pile enters the flip frame through the opening. The flip drive mechanism then activates, causing the flip frame and the pile to synchronously flip longitudinally to the second position, achieving longitudinal adjustment of the pile's posture.

[0008] Preferably, the horizontal flipping drive mechanism includes a first mounting block, a lifting drive member and a rotating drive member, wherein the lifting drive member is used to drive the lifting movement of the first mounting block; the support clamp is rotationally connected to the first mounting block, and the rotating drive member is used to drive the support clamp to rotate.

[0009] Preferably, the flip frame is provided with a flip positioning unit, which includes a flip positioning block and a positioning driver. The flip positioning block is located at one side of the flip frame, and the positioning driver is used to drive the flip positioning block to move.

[0010] Preferably, the longitudinal flipping assembly further comprises an end-to-end tidying mechanism, the end-to-end tidying mechanism comprising an end-to-end tidying block and an end-to-end tidying driving member, the end-to-end tidying driving member drives the end-to-end tidying block to translate in a direction parallel to the rotation center line of the flip frame; the flip frame further comprises at least a third position state, in which the opening of the flip frame is set upward, and the end-to-end tidying block is located at one end of the flip frame.

[0011] During longitudinal flipping, after the material pile enters the flip frame, the flip positioning block compresses the material pile in the thickness direction, preventing it from becoming disorganized during flipping. As the flip frame flips from its first to second position, it pauses in the third position, releasing the flip positioning unit. The end-to-end alignment mechanism then engages, aligning the material pile end-to-end. The flip positioning unit then compresses the material pile again, and flipping continues to the second position. The flip positioning unit and the end-to-end alignment mechanism work together to align the material pile, facilitating subsequent feeding operations.

[0012] Preferably, the horizontal flip drive assembly also includes a sorting control assembly, which includes a second visual detection unit. The second visual detection unit is used to detect the posture of the material pile entering the clamp, provide a basis for determining whether horizontal flipping is required, and control the working state of the horizontal flip assembly.

[0016] During the feeding operation, the stack of materials is delivered to the feed area. The index drive assembly drives the sorting head into the feed area to clamp the stack. The index drive assembly drives the sorting head and the stack of materials to the adjustment module. After horizontal and tilt adjustments, the feed module clamps and completes the feeding operation.

[0017] Preferably, the conveying assembly includes a first segment and a second segment, the first segment and the second segment operate independently, and the longitudinal flipping assembly is located between the first segment and the second segment.

[0018] Preferably, the first segment includes a conveyor belt, and the second segment includes a feeding slider and a feeding drive, and the feeding drive is used to drive the feeding slider to move in translation; when the clamping frame is in the first position, the opening of the clamping frame is aligned with the first segment, and when the clamping frame is in the second position, the opening of the clamping frame is aligned with the feeding slider.

[0041] In order to make the purpose, technical solutions and advantages of 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. Example

[0042] like Figure 1-Figure 5 As shown, an automatic feeding device for thin plate packaging boxes includes a frame 1, a sorting module 2, an adjustment module 3 and a feeding module 4. The frame 1 is provided with a feeding area 11 and an adjustment area 12. Figure 11 As shown, the adjustment area 12 is provided with an adjustment station, a feed station, and a conveyor assembly 6. The conveyor assembly 6 is arranged from the adjustment station to the feed station. Specifically, the adjustment station includes a transition station, a horizontal flip station, and a longitudinal flip station. The transition station, the horizontal flip station, and the longitudinal flip station are arranged in sequence along the conveying direction of the conveyor assembly 6.

[0043] Specifically, such as Figure 11 As shown, the conveying assembly 6 includes a transition mechanism, a first segment 62, and a second segment 63. The transition mechanism corresponds to the inlet end of the first segment 62, and the outlet end of the first segment 62 corresponds to the second segment 63. The transition mechanism includes a lifting platform 612 and a lifting drive unit 611. The lifting platform 612 is movably mounted on the frame 1. The lifting drive unit 611 is used to drive the lifting platform 612 up and down. The lifting platform 612 is provided with a transition drive member, which is used to drive the horizontal movement of the material pile. The first segment 62 and the second segment 63 operate independently. The first segment 62 includes a conveyor belt, and the second segment 63 includes a feed slider and a feed drive member. The feed slider is movably mounted on the frame 1, and the feed drive member is used to drive the feed slider to translate.

[0044] The lifting platform 612 can move up and down relative to the first section 62. When the height of the material stack is high and higher than the first section 62, the lifting platform is lifted to a position higher than the first section 62 and cooperates with the sorting module 2 to receive the material. When the height of the material stack is low and lower than the first section 62, the lifting platform is lowered to a position lower than the first section 62 and cooperates with the sorting module 2 to receive the material, thereby reducing the movement distance of the sorting module 2 and playing a role in balancing the beat.

[0045] like Figure 3-Figure 6 As shown, the sorting module 2 includes a sorting head 21 and an indexing drive assembly 22. The sorting head 21 includes a sorting slider 211, a micro-lifting mechanism and a clamping mechanism. Figure 7-10 As shown, the micro-lift mechanism includes a side plate 212, a lateral clamp 213, and a micro-lift driver. The side plate 212 is fixedly mounted below the sorting slider 211, and the lateral clamp 213 is located on one side of the side plate 212. The lateral clamp 213 includes an opening and closing driver and two parallel, vertically extending clamps. The opening and closing driver is used to drive the clamps to open and close relative to each other. The micro-lift driver is mounted on the side plate 212 and is used to drive the lateral clamp 213 to move up and down relative to the side plate 212.

[0046] like Figure 7-10 As shown, the clamping mechanism includes a plug plate 214 and a plug-in drive. The plug plate 214 is horizontally disposed below the sorting slider 211 and is horizontally slidably connected to the sorting slider 211. The plug-in drive is used to drive the plug plate 214 to move horizontally. The plug-in end of the plug plate 214 is disposed toward the same side as the lateral clamp 213.

[0047] The micro-lifting operation grips the side of the pile and elevates it to a certain height, leaving space on the lower side for the insertion of the insert plate 214. This reduces resistance to insertion, ensures a smooth insertion operation, and minimizes damage to the bottom boxes during insertion. Furthermore, because the pile is loosely stacked, the micro-lifting operation makes it easier for the insert plate 214 to insert even if some boxes at the bottom remain unlifted, given the reduced pressure on the upper boxes. This reduces the amount of boxes left on the pile after sorting. Furthermore, the grip of the lateral clamps 213 can withstand the horizontal thrust applied to the pile by the insert plate 214 during insertion, preventing horizontal movement of the pile during insertion.

[0048] Specifically, the plug end of the plug plate 214 is connected to an elastic plug piece, which is tilted downward in its natural state. The elastic plug piece can guide the plug plate 214 when inserted under the material pile, thereby reducing the amount of material left on the pile after each material pile is sorted.

[0049] Further, such as Figure 7-10As shown, the clamping mechanism also includes a clamping and pressing mechanism 215, which includes a pressure plate and a pressing drive. The pressure plate is positioned between the sorting slider 211 and the inserting plate 214, and is vertically opposed to the inserting plate 214. The pressure plate and the inserting plate 214 form a pressing zone, and the pressing drive is used to drive the pressure plate up and down. During the sorting and transport process, the material pile is located within the pressing zone. The pressure plate and the tray cooperate to press the material pile up and down, achieving reliable clamping, effectively preventing the material pile from scattering during transport, and ensuring smooth sorting and transport.

[0050] The indexing drive assembly 22 is used to drive the sorting slide 211 to move horizontally and vertically, and index between the feed area 11 and the adjustment area 12. The indexing drive assembly 22 includes a transverse indexing drive mechanism, a vertical indexing drive mechanism, and a longitudinal indexing drive mechanism. Specifically, the transverse indexing drive mechanism includes a vertical column 222 and a transverse drive member. The column 222 is slidably connected to the frame 1, and the transverse drive member is used to drive the column 222 to move horizontally. The vertical indexing drive mechanism includes a longitudinal beam 221 and a vertical drive member. The longitudinal beam 221 is horizontally arranged and slidably connected to the column 222. The vertical drive member is mounted on the column 222 and drives the longitudinal beam 221 to move vertically. The longitudinal indexing drive mechanism includes a longitudinal drive member. The sorting slide 211 is slidably mounted on the longitudinal beam 221, and the longitudinal drive member is used to drive the sorting slide 211 along the longitudinal beam 221.

[0051] Further, such as Figure 7-10 As shown, the sorting module 2 further includes a partition picking assembly 23, which includes a negative pressure adsorption unit 232 and a pick-up drive 231. The frame 1 is also provided with a partition storage unit 13. The pick-up drive 231 is used to drive the negative pressure adsorption unit 232 to move horizontally and vertically, and to transfer between the feed area 11 and the partition storage unit 13.

[0052] Specifically, such as Figure 7-10 As shown, the pickup drive 231 includes a main drive unit and an auxiliary drive unit. The negative pressure adsorption unit 232 and the auxiliary drive unit are mounted on the sorting slide 211, with the indexing drive unit serving as the main drive unit. The negative pressure adsorption unit 232 is positioned downward, while the auxiliary drive unit is used to drive the negative pressure adsorption unit 232 up and down. Horizontally, the negative pressure adsorption unit 232 is positioned to correspond to the plug-in end of the plug-in plate 214.

[0053] The packaging box is separated by a partition plate when stacking, and when the sorting and feeding operation of each layer of the material pile is completed, the picking driving member 231 works to drive the negative pressure suction unit 232 to move to the uppermost layer of the partition plate to suction the partition plate and transfer the partition plate to the partition plate storage unit 13, thereby realizing automatic picking of the partition plate and further improving the automation degree of feeding. At the same time, during the process of inserting the plate 214 into the lower part of the material pile, the negative pressure suction unit 232 can move downward under the action of the auxiliary driving unit and press the current material pile or the adjacent material pile, thereby avoiding the movement of the material pile and ensuring the smooth insertion of the plate 214.

[0054] Further, the sorting module 2 further comprises a sorting control assembly, and the sorting control assembly comprises a first visual detection unit.

[0055] As shown in Figure 11 and Figure 12 , the adjustment module 3 is arranged at an adjustment station, and the adjustment module 3 comprises a horizontal turning assembly 31 and a longitudinal turning assembly 32. The adjustment module 3 can perform horizontal turning and longitudinal turning operations on the material pile to ensure that the posture of the material pile is consistent and meets the use requirements when the material pile reaches the feeding station.

[0056] Specifically, as shown in Figure 13 , the horizontal turning assembly 31 comprises a supporting clamp 311 and a horizontal turning driving mechanism, the supporting clamp 311 comprises two supporting arms which are arranged in parallel along the vertical direction, the conveying assembly 6 is located between the two supporting arms, and the inner sides of the two supporting arms are respectively provided with supporting plates. The horizontal turning driving mechanism is used for driving the supporting clamp to move up and down and rotate around the vertical center line.

[0057] As shown in Figure 13 , the horizontal turning driving mechanism comprises a first mounting block, a lifting driving member 313 and a rotating driving member 312, the lifting driving member 313 is arranged on the rack 1 and is used for driving the first mounting block to move up and down. The supporting clamp 311 is rotatably connected with the first mounting block, and the rotating driving member 312 is used for driving the supporting clamp 311 to rotate.

[0058] When the horizontal turning operation is performed, the conveying assembly 6 sends the material pile into the two supporting arms, the lifting driving member 313 drives the supporting clamp 311 and the material pile to move up synchronously, and then the rotating driving member 312 drives the first mounting block, the supporting clamp 311 and the material pile to rotate horizontally synchronously, thereby realizing the posture adjustment of the material pile in the horizontal direction.

[0059] The horizontal flip drive assembly also includes a sorting control assembly, which includes a second visual inspection unit. The second visual inspection unit is disposed above and toward the conveyor assembly 6. In the conveying direction along the conveyor assembly 6, the second visual inspection unit is aligned with or located in front of the support clamp 311. The second visual inspection unit is used to detect the posture of the material pile entering the support clamp 311, providing a basis for determining whether horizontal flipping is required and controlling the operating state of the horizontal flip assembly 31.

[0060] Specifically, such as Figure 14 As shown, the longitudinal flip assembly 32 includes a flip frame 321 and a longitudinal flip drive mechanism 323. The longitudinal flip drive mechanism 323 is used to drive the flip frame 321 to rotate, and the rotation center line is located in the horizontal plane and is perpendicular to the conveying direction of the conveying assembly 6. The flip frame 321 has at least two position states, such as Figure 15 As shown, in the first position, the opening of the flip frame 321 is arranged toward the inlet end of the conveying assembly 6, as shown in FIG. Figure 17 As shown, in the second position, the opening of the flip frame 321 is arranged toward the outlet end of the conveying assembly 6.

[0061] During the longitudinal flipping operation, the flip frame 321 is first in the first position, the conveying assembly 6 conveys the material pile and enters the flip frame 321 from the opening. Then, the flip drive mechanism is activated, and the flip frame 321 and the material pile are synchronously flipped longitudinally to the second position, and the material pile falls back onto the conveying assembly 6, achieving longitudinal posture adjustment of the material pile.

[0062] like Figure 14-17 As shown, the flip frame 321 is provided with a flip positioning unit 324, and the flip positioning unit 324 includes a flip positioning block and a positioning driver. The flip positioning block is located on one side of the flip frame 321, and the positioning driver is used to drive the flip positioning block to move.

[0063] Further, such as Figure 14-17 As shown, the longitudinal flip assembly 32 further includes an end-to-end arrangement mechanism 322, which includes an end-to-end arrangement block and an end-to-end arrangement driving member. The end-to-end arrangement driving member drives the end-to-end arrangement block to translate in a direction parallel to the rotation centerline of the flip frame 321. The flip frame 321 has at least a third position state, such as Figure 16 As shown, in the third position, the opening of the flip frame 321 is set upward, and the end-to-end arranging block is located at one end of the flip frame 321.

[0064] During longitudinal flipping, after the pile enters flip frame 321, the flip positioning block compresses the pile in the thickness direction to prevent it from becoming disorganized during flipping. As flip frame 321 flips from its first position to its second position, it pauses in the third position, releasing the flip positioning unit 324. The end-to-end alignment mechanism 322 then activates, aligning the pile end-to-end. The flip positioning unit 324 then compresses the pile again, continuing flipping to the second position. The flip positioning unit 324 and end-to-end alignment mechanism 322 work together to align the pile, facilitating subsequent feeding operations.

[0065] like Figure 11 As shown, the longitudinal flip assembly 32 is located between the first segment 62 and the second segment 63. When the clamping frame is in the first position, the opening of the clamping frame is aligned with the first segment 62. When the clamping frame is in the second position, the opening of the clamping frame is aligned with the feed slider. The independent arrangement of the first segment 62 and the second segment 63 not only improves the coordination between the clamping frame and the machine, but also enables independent operation of the adjustment module 3 and the feed module 4, facilitating the adjustment of the overall operating rhythm of the equipment.

[0066] Specifically, such as Figure 14 As shown, both sides of the flip frame 321 are provided with slots matching the conveying assembly 6. When the flip frame 321 is in the first position and the second position, the material pile can be seamlessly connected to the conveying assembly 6 to ensure smooth transportation.

[0067] like Figure 18 and Figure 19 As shown, the feeding module 4 is arranged at the feeding station and includes a gripping manipulator 43 and a feeding drive assembly. The feeding drive assembly is used to drive the gripping manipulator 43 to move in the vertical and horizontal directions. The feeding module 4 can automatically complete the gripping and feeding operations of the material pile for subsequent packaging of the packaging box.

[0068] Specifically, such as Figure 18 and Figure 19 As shown, the feed drive assembly includes a feed bracket 41 and a clamping arm 42, and the clamping manipulator 43 is disposed on the clamping arm 42. The feed bracket 41 is horizontally slidably connected to the frame 1, and the frame 1 is also provided with a horizontal feed drive member that drives the feed bracket 41. The clamping arm 42 is vertically slidably connected to the feed bracket 41, and the feed bracket 41 is also provided with a vertical feed drive member that drives the clamping arm 42 up and down.

[0069] The horizontal feed drive is used to drive the feed bracket 41, the clamping cantilever 42 and the clamping manipulator 43 to move horizontally synchronously, and the vertical feed drive is used to drive the clamping cantilever 42 and the clamping manipulator 43 to move vertically synchronously. The horizontal feed drive and the vertical feed drive work together to complete the feeding operation of the material pile.

[0070] Specifically, such as Figure 20 and Figure 21 As shown, the clamping robot 43 includes a clamping seat, and the clamping seat is provided with a long clamping jaw 432 and a short clamping jaw 431. The long clamping jaw 432 includes a first clamping drive and two groups of long clamping arms arranged in parallel, and the first clamping drive is used to drive the two groups of long clamping arms to move relative to each other. The short clamping jaw 431 includes a second clamping drive and two groups of short clamping arms arranged in parallel, and the second clamping drive is used to drive the two groups of short clamping arms arranged in parallel to each other. The long clamping arm and the short clamping arm are both arranged in the vertical direction and enclose a clamping interval, and the lower end of the short clamping arm is arranged higher than the lower end of the long clamping arm. Specifically, a receiving block is provided on the inner side of the lower end of the long clamping jaw 432.

[0071] During the feeding operation, the conveyor assembly 6 transports the material pile to the feeding station. The long jaw 432 in the clamping robot 43 grips the material pile and lifts it off the conveyor assembly 6. At this time, the short jaw 431 is in a loosened state. During feeding, the short jaw 431 grips the material pile, while the long jaw 432 releases the material pile. Due to the height difference between the lower ends of the short and long clamp arms, the packaging boxes between the long jaw 432 and the lower end of the short jaw 431 can fall freely to feed the material, while the packaging boxes on the upper layer are still clamped by the short jaw 431. The long jaw 432 then closes and the short jaw 431 releases, allowing the material pile to fall onto the long jaw 432. By again closing the long jaw 432 and opening the short jaw 431, the packaging boxes are fed in batches and in fixed quantities. The long jaw 432 and the short jaw 431 cooperate to sequentially release and clamp the material pile, achieving fixed-quantity feeding of the material pile.

[0072] When the material stack 5 is being fed into the feeding area 11, the transfer drive assembly 22 drives the sorting head 21 to move into the feeding area 11 and aligns it with one of the material piles 51 on the top layer of the material stack 5. The lateral clamp 213 clamps the side of the corresponding material pile 51, and the micro-lifting drive drives the lateral joint to lift a certain height, and drives the corresponding side of the material pile 51 to lift and tilt, completing the micro-lifting operation. The plug-in drive works to drive the plug plate 214 to insert from the bottom of the raised side of the corresponding material pile under the material pile 51, and the material pile is placed on the plug plate 214 to complete the plug-in operation and achieve reliable clamping of the material pile. The transfer drive assembly 22 drives the sorting head 21 and the material pile to transfer to the adjustment module 3. After the horizontal posture adjustment and flipping adjustment, they are clamped by the feeding module 4 and the feeding operation is completed.

[0073] The automated feeding equipment of the present application can improve the integrity of material pile sorting through micro-lifting operations, and has the advantage of a high degree of automation.

[0074] An automated feeding method for thin-plate packaging boxes, using the automated feeding equipment described above, includes at least the following steps:

[0075] S1. Sorting: Send the stack 5 to the feeding area 11 and determine whether there is a pile 51 on the top layer of the stack 5. If there is a pile 51 on the top layer, proceed to step S11; if there is no pile 51 on the top layer, proceed to step S13.

[0076] S11. Gripping: The index drive assembly 22 operates, driving the sorting head 21 to the height of the topmost layer of boxes in the stack 5 and aligning it with one of the piles 51. The lateral gripper 213 engages, gripping the pile 51 from one side. The micro-lift drive raises the lateral gripper 213 to a certain height, simultaneously raising the corresponding side of the pile 51. The plug-in drive drives the plug plate 214 to insert from the bottom of the corresponding side of the pile 51 underneath, thereby receiving the pile 51.

[0077] S12. Indexing: The indexing drive assembly 22 drives the sorting head 21 and the material pile 51 to index onto the conveying assembly 6 in the adjustment area 12, and then proceeds to step S2.

[0078] S13. Picking up the partition: The picking drive 231 drives the negative pressure adsorption unit 232 to move above the material stack 5, adsorbs the partition, and transfers it to the partition storage unit 13.

[0079] S2. Posture adjustment: The conveying assembly 6 works to convey the pile 51 to the horizontal flipping station in the adjustment station and into the space between the support clamps 311 .

[0080] S21. Horizontal Flip: The sorting control assembly determines whether the current material pile 51 requires horizontal flipping. If so, the horizontal flip drive mechanism activates, driving the bracket and material pile 51 upward, flipping it 180° horizontally, and then descending, allowing the material pile 51 to land back on the conveyor assembly 6. If not, the conveyor assembly 6 continues to operate, driving the material pile 51 forward to the longitudinal flipping station.

[0081] S22. Longitudinal Turnover: Initially, the turning frame 321 is in the first position. The material pile 51 enters the turning frame 321 through the opening, and the turning positioning unit 324 clamps the material pile 51. The longitudinal turning drive mechanism 323 activates, turning the turning frame 321 to the third position. The turning positioning unit 324 releases the material pile 51. The end alignment mechanism 322 activates, pushing the material pile 51 end-to-end into alignment. The turning positioning unit 324 re-compresses the material pile 51. The longitudinal turning drive mechanism 323 activates, turning the turning frame 321 to the second position. The turning positioning unit 324 releases, and the material pile 51 falls onto the conveyor assembly 6.

[0082] S3. Feeding: The conveyor assembly 6 operates to transport the material pile 51 to the feeding station. The long jaws 432 grasp the material pile 51 and lift it off the conveyor assembly 6. The feed drive assembly drives the gripper manipulator 43 to transfer to the material receiving equipment. The short jaws 431 grasp the material pile 51, and the long jaws 432 release the material pile 51. The packaging boxes between the long jaws 432 and the lower ends of the short jaws 431 fall freely to feed the material. The long jaws 432 then close, and the short jaws 431 release, allowing the material pile 51 to fall onto the long jaws 432, completing a single quantitative feeding. The long jaws 432 and short jaws 431 then open sequentially until the material pile 51 is fed in a quantitative manner.

[0083] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
