Description

TECHNICAL FIELD

[0001] The present application relates to a carton forming device and method. BACKGROUND

[0002] At present, the paper box (such as a square cylinder) usually adopts the method of first misaligning the whole face paper (which can correspond to four boards and a bottom plate) with the four boards, then pasting the four boards with the four side walls of the carton body, and the bottom plate corresponding to the bottom of the carton bottom. In the production process, the whole face paper is first glued, then transported to the positioning machine (i.e. the cover machine), and the four boards are moved and placed on the glued whole face paper to paste and combine (misaligning one side wall position) to form a combined material, which is moved to surround and form on a horizontal forming mold. The bottom plate is first installed on the front side of the horizontal forming mold radially outward, and the bottom plate is moved to the position with the combined material to form the body, and then the horizontal forming mold carries the body to the subsequent forming, such as CN104842586A paper box forming machine, CN218286882U paper box forming equipment production line, CN216032797U A new type of paper box cover machine and paper box production line, CN215243189U A paper box forming production line and the like. Among them, the four boards and the whole face paper are pasted and combined, and then assembled with the pre-installed bottom plate of the horizontal forming mold. The method is relatively single and does not break through the forming method. In addition, after the four boards and the bottom plate are assembled, the face paper is additionally pasted on the outside of the bottom plate, which is easy to cause the edge of the bottom plate and the face paper to be pasted irregularly. The subsequent increase of the bottom support (used to hold the articles placed in the paper box) needs to be separately and additionally assembled, which is relatively troublesome. Among them, the position accuracy of the material after the whole face paper and the paper board are pasted and combined is also very important. If the position deviates, it will affect the smooth forming and the quality of the paper box forming. SUMMARY

When the horizontal forming die J22 is at rest at the horizontal die resting position two E8, the horizontal forming die J22 carries the surrounded three-plate J21 to rest at this position, and the box body forming and pasting mechanism A6 cooperates to form and paste the box body.

[0054] The paper box forming machine A4 also has a horizontal die resting position three, which can be used as a reserved position. According to the requirements, corresponding mechanisms can be set, for example, a fourth edge covering mechanism A16 (a mature technology) can be set to cover the upper edge of the paper box (in a horizontal state), and an upper lifting and lowering pressure plate mechanism A17 and a lower lifting and lowering pressure plate mechanism A18 are respectively arranged on the upper and lower sides of the horizontal forming die J22 (for pressing and clamping the paper box, pressing the box body, and also being able to fix the paper box for edge covering).

[0055] The demolding mechanism A9 has a horizontal mold resting position four, and the demolding mechanism A9 has many modes and is relatively mature in technology. The horizontal mold resting position four can be used to hook, suck, clamp or support the paper box body on the horizontal forming mold J22 to remove the demolding (remove along the radial direction of the mold rotation), and a motor A11 or a pneumatic cylinder can also be used to drive the operation.

[0056] The horizontal forming mold J22 is connected to the intermittently indexed vertical main shaft H14, and the horizontal forming mold J22 revolves with the vertical main shaft H14. The vertical main shaft H14 drives the horizontal forming mold J22 to revolve, so that the horizontal forming mold J22 stops at the corresponding resting position in turn. The intermittently indexed vertical main shaft can be driven by a motor (such as a servo motor) to rotate intermittently, or a corresponding indexing box divider can be configured to cooperate with the drive.

[0057] The horizontal mold resting position one J2, the horizontal mold resting position two E8, the horizontal mold resting position three, and the horizontal mold resting position four are arranged in turn along the circumferential direction of the vertical main shaft H14 to form a circle. The horizontal forming mold J22 is driven by the vertical main shaft H14 to first stop at the horizontal mold resting position one J2 to complete the assembly of the three-plate J21, then revolves to the horizontal mold resting position two to complete the box body forming and pasting, then revolves to the horizontal mold resting position three, and finally revolves to the horizontal mold resting position four to demold the paper box body. Then the horizontal forming mold J22 revolves back to the horizontal mold resting position one J2 to perform a new round of work. The four horizontal forming molds are evenly arranged in the circumferential direction, so that during rotation, each horizontal mold resting position has a mold to stop and operate, which is more efficient.

[0058] When the paper box forming equipment is running, the whole paper is supplied by the paper feeding device A1, and after being coated by the coating machine A2, the single-sided wall paper board with the bottom plate and the paper (whole paper) are positioned and pasted in the positioning machine A3 to form material F30. The material F30 is then moved to the material supply station F1 by the material feeding manipulator F3, and the material F30 is moved to the forming and pasting station F2 by the material feeding manipulator F3. In addition, the three-plate J21 (paperboard) is surrounded on the left side, upper side and right side of the resting horizontal forming mold J22 at the three-plate assembly station J1, and the three-plate J21 is moved to the forming and pasting station F2 by the horizontal forming mold J22, and is pasted with the material F30 below to form a paper box body.

[0059] The paper box forming method, the whole face paper has four side paper parts corresponding to the four side wall paper boards of the paper box and a bottom paper part corresponding to the bottom board of the paper box, and the whole face paper is pasted and combined with the single side wall paper board and the bottom board in the corresponding position after being glued to form material F30, wherein the single side wall paper board corresponds to the front and back of the bottom board, and the three edges of the bottom paper part have protruding edge paper parts for folding and covering on the paper box side wall paper board; the three-plate J21 is enclosed in the horizontal forming mold J22 on the left side, the upper side and the right side, the material F30 is located below the horizontal forming mold J22 which has moved to the position in the forming and pasting station F2, and the material F30 is wrapped outside the horizontal forming mold J22 which has carried the enclosed three-plate J21, wherein the single side wall paper board and the corresponding part of the face paper are pushed up to the lower side of the horizontal forming mold J22, the bottom board and the corresponding part of the face paper are turned over to the front side of the horizontal forming mold J22, and the protruding edge paper parts of the three edges of the bottom paper part are respectively folded and covered outside the three-plate J21 on the left side, the upper side and the right side of the horizontal forming mold J22, the front side of the horizontal forming mold J22 corresponds to the bottom part of the paper box, and the other face paper parts are pasted and enclosed on the left side, the right side and the upper side of the horizontal forming mold J22 to complete the forming of the body of the paper box. In the paper box forming equipment and the paper box forming method, the material after the single side wall paper board is matched with the bottom board and pasted with the face paper can be assembled with the three-plate J21 to form the body of the paper box to form the main structure of the body of the paper box, the edge position of the bottom of the box is relatively neat, the bottom board is not easy to be skewed, and the face paper pasted outside the bottom board is relatively neat. The horizontal mold stopping position is reserved in the paper box forming equipment so that the edge of the box can be wrapped.

[0060] The following optimizations or further descriptions can be made on the basis of the above embodiments respectively.

[0061] For example, the single side wall paper board is matched with the bottom board and pasted with the face paper in the positioning mechanism G0 of the embodiment, and the pasting positioning mechanism comprises a paper board material warehouse G1, a material conveying belt G2, a paper board conveying device G3 and a paper board conveying mechanical hand G4.

[0062] The paper board material warehouse G1 is used to store materials (containing single side wall paper boards and bottom boards) for pushing out, the paper board material warehouse G1 comprises a single side wall paper board material area G5 and a bottom board material area G6, the single side wall paper boards are placed in the single side wall paper board material area G5 in correspondence, and the bottom boards are placed in the bottom board material area G6 in correspondence, wherein the single side wall paper boards correspond to one side wall of the paper box, and the bottom boards correspond to the bottom of the paper box.

[0063] The bottom board material area G6 is located on the left side or the right side of the single side wall paper board material area G5, and after the materials are placed, the bottom board will be located on the left side or the right side of the single side wall paper board.

[0064] The paperboard positioning and waiting station G7 is arranged between the paperboard warehouse G1 and the material conveying belt G2, and the paperboard positioning and waiting station G7 is connected with the paperboard warehouse G1 by the paperboard feeding device G3. The paperboard feeding device G3 cooperates to push the paperboard material (including single-sided wall paperboard and bottom plate) in the paperboard warehouse G1 out and convey it to the paperboard positioning and waiting station G7. The single-sided wall paperboard and the bottom plate are pushed out from the paperboard warehouse G1 to the paperboard positioning and waiting station G7, so that the relative position of the single-sided wall paperboard and the bottom plate is positioned, and the single-sided wall paperboard and the bottom plate are in a set and clear initial position, waiting to be taken away subsequently.

[0065] The paperboard feeding device G3 includes a paperboard feeding push head G9, which cooperates with the single-sided wall paperboard and the bottom plate in the paperboard warehouse G1 to push them out. The paperboard feeding push head G9 in the paperboard feeding device G3 can be driven and operated by a cylinder or a motor (which can be equipped with a belt pulley transmission structure). When advancing, the single-sided wall paperboard and the bottom plate at the bottom of the paperboard material bin are pushed out, and after being pushed into place, the paperboard feeding push head G9 is retracted for resetting.

[0066] The feeding path of the material conveying belt G2 is arranged orthogonally to the paperboard feeding path of the paperboard feeding push head G9, for example, the feeding path of the material conveying belt G2 is the left-right direction, and the paperboard feeding path (i.e. the pushing direction) of the paperboard feeding push head G9 is the front-back direction. The material conveying belt G2 can be provided in multiple sections, which can not only be connected with the gluing machine, but also be connected to the material feeding station.

[0067] The paperboard positioning and waiting station G7 is connected with the material conveying belt G2 by the paperboard transfer mechanical hand G4, which cooperates to take away the single-sided wall paperboard and the bottom plate at the paperboard positioning and waiting station G7 and transfer and place them on the material conveying belt G2, and then paste and adhere them on the surface paper conveyed by the material conveying belt G2, and then continue to convey them by the material conveying belt G2.

[0068] The paperboard transfer mechanical hand G4 includes a transfer and taking and placing piece G10, which rotates and switches the position of the material (including single-sided wall paperboard and bottom plate) horizontally and vertically, i.e. the single-sided wall paperboard and the bottom plate at the paperboard positioning and waiting station G7 are arranged horizontally, and by rotating, the single-sided wall paperboard and the bottom plate placed on the surface paper of the material conveying belt G2 are arranged vertically, usually by 90 degrees.

[0069] The working principle is that the material (containing single-sided wall paperboard and bottom plate) is placed in the corresponding position of the paperboard warehouse G1, and then a single-sided wall paperboard and a bottom plate are pushed out to the paperboard positioning waiting station G7 by the paperboard pushing head G9. The position of the single-sided wall paperboard and the bottom plate is positioned, and then the single-sided wall paperboard and the bottom plate at the paperboard positioning waiting station G7 are taken away and transferred to the surface paper of the material conveying belt G2 by the paperboard transfer manipulator G4. During the taking away and transferring process, the paperboard transfer manipulator G4 also rotates the position direction of the single-sided wall paperboard and the bottom plate, switches the lateral rotation of the material to the longitudinal direction (i.e. switches the left and right lateral arrangement of the single-sided wall paperboard and the bottom plate to the front and back longitudinal arrangement), so that the paper of the pasting box bottom of the surface paper can be directly pasted with the bottom plate, the bottom plate can be directly assembled and pasted on the surface paper, and the requirements different from the existing paper box forming process can be met. Also, the assembly requirements of the bottom plate with a bottom support (used to support the articles placed in the paper box) can be met.

[0070] The single-sided wall paperboard and bottom plate and surface paper pasting positioning mechanism can assemble the material of the single-sided wall paperboard and the bottom plate with the surface paper, directly assemble and paste the bottom plate on the surface paper, and meet the requirements different from the existing paper box forming process. In addition, if the bottom plate has a bottom support, it can also be successfully assembled. Compared with the previous way of assembling the four-sided wall paperboard and the surface paper, and assembling the bottom plate in the forming mechanism, a new optional assembly method is added.

[0071] The following optimizations or further explanations can also be made.

[0072] For example, the bottom of the single-sided wall paperboard area G5 and the bottom of the bottom plate area G6 are provided with an output port for pushing out a single sheet. The single-sided wall paperboard and the bottom plate will be pushed out one by one from the output port at the bottom of the paperboard warehouse G1 to the paperboard positioning waiting station G7. The paperboard pushing head G9 is arranged at the bottom of the paperboard warehouse G1. The cooperation mode of the paperboard warehouse G1 and the paperboard pushing head G9 is relatively mature. In this embodiment, the paperboard warehouse G1 is provided with left and right arranged single-sided wall paperboard area G5 and bottom plate area G6.

[0073] For example, the single-sided wall paperboard area G5 and the bottom plate area G6 of the paperboard warehouse G1 are arranged side by side or staggered front and back.

[0074] Further optimization can also be made by leaving a bottom support output port at the output side of the bottom plate area G6, so that when the bottom support is preinstalled on the bottom plate, the bottom support output can smoothly output the bottom support, and the paper box is formed with a bottom support inside directly, without the need for additional assembly of the bottom support in the paper box, which is more convenient.

[0075] The front side of the paperboard warehouse G1 can be provided with a front baffle G11, and the gap between the front baffle G11 and the lower material supporting rail G21 can be used as an output port. The height position of the front baffle G11 can be adjusted, and the size of the output port will also be adjusted. In addition, the spacing between the front baffles G11 can be used as a bottom supporting output port.

[0076] The single-sided wall paperboard and the bottom plate are positioned at the paperboard positioning waiting station G7, and the positioning mode is various. For example, the paperboard positioning waiting station G7 is provided with a front moving stop gauge G12, a left stop gauge G13, and a right stop gauge G14. The structure is relatively simple. The single-sided wall paperboard and the bottom plate are only pushed forward, and then the front moving stop gauge G12 in front can stop and position the single-sided wall paperboard and the bottom plate, and the left stop gauge G13 and the right stop gauge G14 on the left and right sides can also cooperate to position the single-sided wall paperboard and the bottom plate. In addition, the left stop gauge G13 and the right stop gauge G14 are connected with the output end of the paperboard warehouse G1, respectively. After the single-sided wall paperboard and the bottom plate are output from the output port (i.e., the output end position) of the paperboard warehouse G1, they can be located between the left stop gauge G13 and the right stop gauge G14. During the pushing process, the single-sided wall paperboard and the bottom plate are directly constrained on the left and right sides and cannot be moved left and right.

[0077] The transfer taking and placing part G10 includes a lifting air nozzle G15 (not shown in the figure). The single-sided wall paperboard and the bottom plate are sucked and obtained and released by the lifting air nozzle G15. The lifting air nozzle G15 in the paperboard transfer mechanical arm G4 moves to cooperate with the transfer of the single-sided wall paperboard and the bottom plate. The lifting air nozzle in the paperboard transfer mechanical arm G4 is controlled by a moving module that can lift, rotate (around the vertical axis), move forward and backward, and move left and right, or by an industrial robot. For example, the paperboard transfer mechanical arm G4 further includes a first paperboard transfer mechanical rotating arm G16 and a second paperboard transfer mechanical rotating arm G17. The first paperboard transfer mechanical rotating arm G16 is arranged on the second paperboard transfer mechanical rotating arm G17 through a first vertical shaft. The first paperboard transfer mechanical rotating arm G16 can rotate around the first vertical shaft on the second paperboard transfer mechanical rotating arm G17. The second paperboard transfer mechanical rotating arm G17 is arranged on the base G18 through a second vertical shaft. The second paperboard transfer mechanical rotating arm G17 can rotate around the second vertical shaft on the base G18. The lifting air nozzle G15 is connected to the first paperboard transfer mechanical rotating arm G16 and can also lift on the first paperboard transfer mechanical rotating arm G16. The first paperboard transfer mechanical rotating arm G16 is further provided with a lifting shaft, and the lifting air nozzle G15 is connected to the lifting shaft. Even the lifting shaft can be rotatably arranged on the first paperboard transfer mechanical rotating arm G16, and the lifting air nozzle G15 is located below the first paperboard transfer mechanical rotating arm G16.

[0078] The material conveying belt G2 can be further optimized, and a visual sensor (such as an industrial camera, a camera, etc., not shown in the figure) is further arranged above the material conveying belt G2, the visual sensor is electrically connected with the paperboard transfer manipulator G4, the relative position signal of the face paper conveyed by the material conveying belt G2 is collected by the visual sensor, and the signal is fed back to cooperate with the operation of the paperboard transfer manipulator G4. Even if the position of the face paper on the material conveying belt G2 is slightly deviated, the position signal of the face paper can be obtained through the visual sensor, so that the subsequent single-sided wall paperboard and bottom plate rotation angle is more accurate, and the horizontal and vertical rotation switching is more accurate.

[0079] For example, the first paperboard transfer manipulator rotating arm G16 is provided with a first rotating drive motor, and the first paperboard transfer manipulator rotating arm G16 is driven to rotate by the first rotating drive motor; the second paperboard transfer manipulator rotating arm G17 is provided with a second rotating drive motor, and the second paperboard transfer manipulator rotating arm G17 is driven to rotate by the second rotating drive motor. The lifting shaft is provided with a third rotating drive motor, and the lifting shaft is driven to rotate by the third rotating drive motor. The lifting shaft is also provided with a lifting drive power component (such as a motor or a pneumatic cylinder, etc.), and the lifting drive power component drives the lifting shaft to lift. For example, the first rotating drive motor is a servo motor, the second rotating drive motor is a servo motor, and the third rotating drive motor can also be a servo motor. Each servo motor is electrically connected with a controller (such as a PLC controller, etc.), and the controller is electrically connected with a visual sensor. The lifting drive power component can also be electrically connected with the controller, and the controller cooperates with the lifting drive power component to lift.

[0080] The single-sided wall paperboard material area G5 and the bottom plate material area G6 have a material separation plate G19, which can separate the single-sided wall paperboard and the bottom plate. It is suitable for single-sided wall paperboard and bottom plate with split structure, and also suitable for materials with bottom support structure on the bottom plate. The paperboard positioning waiting station G7 is also provided with a partition plate G20, and the material separation plate G19 and the partition plate G20 are connected in front and back, which facilitates the smooth and stable pushing of the single-sided wall paperboard and the bottom plate. Alternatively, the single-sided wall paperboard material area G5 and the bottom plate material area G6 are connected, which is suitable for single-sided wall paperboard and bottom plate with split structure, and generally has a slot (such as a V-shaped slot) between the single-sided wall paperboard and the bottom plate.

[0081] In addition, the gluing positioning mechanism further comprises a plurality of material supporting rails G21, and the paperboard material warehouse G1 comprises a material warehouse baffle G22, which is arranged on the material supporting rail G21. For example, the material warehouse baffle G22 has left and right material warehouse baffles G22, and the left and right baffles G13 and G14 are also arranged on the material supporting rail G21 and can be adjusted in the left and right positions of the corresponding material supporting rail G21 to adapt to single-wall paperboards and bottom plates of different sizes. The left and right positions of the material supporting rail G21 can be adjusted on the horizontal rail, and a motor (through a belt) can be driven or manually driven for adjustment. After adjustment, the position is usually locked by fasteners and the like. If the material separating plate G19 and the separating plate G20 are configured, the material separating plate G19 can also be arranged on the material supporting rail G21, and the separating plate G20 is arranged on the material supporting rail G21 and adjusted in the left and right positions of the corresponding material supporting rail G21 to adapt to materials of different sizes.

[0082] Referring to the drawings, the material transfer manipulator of the paperboard and face paper transfer mechanism of the carton forming equipment in the embodiment can adopt an industrial manipulator with a material suction and release nozzle. Alternatively, the material transfer manipulator comprises a transfer frame, a lifting support and a material suction and release nozzle. The transfer frame is arranged to move back and forth between the material supply station and the forming and gluing station. The lifting support is connected to the transfer frame, and the material suction and release nozzle is connected to the lifting support. The material suction and release nozzle can not only perform lifting action, but also move back and forth between the stations with the transfer frame. The material is transferred by the material suction and release nozzle.

[0083] The material transfer manipulator F3 connects the material supply station F1 and the forming and gluing station F2. The material transfer manipulator F3 connects the material supply station F1 and the forming and gluing station F2. The material supply station F1 is arranged on the front side of the forming and gluing station F2. The material transfer manipulator F3 can transfer the material F30 (such as paperboard and face paper gluing material, and even some paperboards have product supporting seats) at the material supply station F1 to the forming and gluing station F2. The position of the material F30 at the material supply station F1 may be deviated, and the material position needs to be adjusted before being placed in the forming and gluing station F2 to ensure subsequent processing (such as box body forming and box body outer wall gluing).

[0084] In this embodiment, the material taking and placing suction nozzle F10 of the material transfer robot F3 moves to find the material F30 (position deviation needs fine adjustment), then acquires (such as suction) the material, and then the material transfer robot F3 transfers the material to the molding and pasting station F2 to release the material. The material taking and placing suction nozzle F10 can move relatively to adjust the relative position of the material in the material transfer robot F3 after acquiring the material (it can be set to return to the original position after finding the material), so as to realize the fine adjustment of the material position, and cooperate to make the material in the preset (i.e. accurate) position in the molding and pasting station F2, to ensure subsequent processing in the molding and pasting station F2.

[0085] In this embodiment, as preferred, the material transfer robot F3 includes a left sliding plate F4, a left rotating arm F5, a right sliding plate F6, a right rotating arm F7, a transfer frame F8, a lifting support F9, a material taking and placing suction nozzle F10, and a horizontal movement transmission and driving device F11.

[0086] The left sliding plate F4 is arranged on the left guide rail F24, so that the left sliding plate F4 moves forward and backward on the left guide rail F24. The left sliding plate F4 is in transmission connection with the left motor F25, and is driven by the left motor F25 to move on the left guide rail F24. The left rotating arm F5 is connected to the left sliding plate F4 through the left vertical rotating shaft F26, and rotates on the left sliding plate F4 around the left vertical rotating shaft F26. When the left sliding plate F4 moves forward and backward, the left rotating arm F5 and the left vertical rotating shaft F26 also move forward and backward together.

[0087] The right sliding plate F6 is arranged on the right guide rail F27, so that the right sliding plate F6 moves forward and backward on the right guide rail F27. The right sliding plate F6 is in transmission connection with the right motor F28, and is driven by the right motor F28 to move on the right guide rail F27. The right rotating arm F7 is connected to the right sliding plate F6 through the right vertical rotating shaft F29, and rotates on the right sliding plate F6 around the right vertical rotating shaft F29. When the right sliding plate F6 moves forward and backward, the right rotating arm F7 and the right vertical rotating shaft F29 also move forward and backward together.

[0088] The double-sliding-plate and double-motor corresponding structure formed by the left sliding plate F4, the right sliding plate F6, the left motor F25 and the right motor F28 enables the left sliding plate F4 and the right sliding plate F6 to move forward and backward on their respective guide rails synchronously, or asynchronously (for example, one of the sliding plates stops moving, and the other sliding plate can still move forward and backward to adjust the position), and the left sliding plate F4 and the right sliding plate F6 can move independently.

[0089] The horizontal moving guide rail pair F12 is connected between the left rotating arm F5 and the moving frame F8, and the horizontal moving guide rail pair F12 is connected between the right rotating arm F7 and the moving frame F8, which can share the horizontal moving guide rail pair F12 or separately configure the horizontal moving guide rail pair F12; the moving frame F8 is connected to the left rotating arm F5 and the right rotating arm F7 through the horizontal moving guide rail pair F12, and the moving frame F8 can move forward and backward with the left sliding plate F4 and the right sliding plate F6, and the existence of the horizontal moving guide rail pair F12 enables the moving frame F8 to move left and right relative to the left rotating arm F5 and the right rotating arm F7 along the direction of the horizontal moving guide rail pair F12, and the left rotating arm can rotate on the left sliding plate F4, and the right rotating arm can rotate on the right sliding plate F6, so that the moving frame F8 can be adjusted in position relative to the rotation when the left sliding plate F4 and the right sliding plate F6 move asynchronously (forward and backward).

[0090] The horizontal moving transmission driving device F11 is connected between the moving frame F8 and the left rotating arm F5 or the right rotating arm F7, and the horizontal moving transmission driving device F11 can drive the moving frame F8 to move back and forth relative to the left rotating arm F5 or the right rotating arm F7 along the horizontal moving guide rail pair F12.

[0091] The lifting support F9 is connected to the moving frame F8, and the lifting support F9 can move with the moving frame F8 (including overall forward and backward movement, rotation around the left vertical rotating shaft F26 or the right vertical rotating shaft F29, and back and forth movement along the horizontal moving guide rail pair F12); in addition, the lifting support F9 can also perform lifting action, and the lifting action can lift the entire structure, or only the lifting support F9 can be relatively arranged on the moving frame F8.

[0092] The material suction nozzle F10 can cooperate with the suction material F30 and release the material, and the material suction nozzle F10 is connected to the lifting support F9, and the material suction nozzle can also lift with the lifting support F9 and move with the moving frame F8 together, and cooperate with the material taking and placing and the moving adjustment position (overall forward and backward movement, rotation around the left vertical rotating shaft F26 or the right vertical rotating shaft F29, and back and forth movement along the horizontal moving guide rail pair F12).

[0093] The material transfer robot F3 obtains the material F30 from the material supply station F1, which may have a positional deviation. The material is directly placed in the forming and pasting station F2 without changing the relative position, which affects the subsequent processing and manufacturing. After the material is obtained by the material transfer robot F3, it can be rotated by the forward and backward asynchronous movement of the left slide F4 and the right slide F6 (the movement stroke can also have a difference), and can be horizontally moved by the horizontal movement transmission driving device F11. The position of the material is fine-tuned, the position of the paperboard face paper is fine-tuned after the material is transferred from the position deviation, and finally placed in the forming and pasting station F2 for subsequent forming. Of course, during operation, if the material does not have a positional deviation, the left slide F4 and the right slide F6 can move synchronously (the movement stroke is consistent), and even do not need to be horizontally moved by the horizontal movement transmission driving device F11.

[0094] The paperboard face paper transfer mechanism of the carton forming equipment is connected and cooperated by the material transfer robot F3 between the material supply station F1 and the forming and pasting station F2 to transfer the material. After the material is obtained from the material supply station F1 (which needs to be fine-tuned due to the positional deviation), the transfer frame can be rotated by the left and right asynchronous operation of the left slide F4 and the right slide F6, and the material position can be fine-tuned by the horizontal movement of the transfer frame F8 along the horizontal movement guide pair F12, to ensure that the material placed in the forming and pasting station F2 is in the preset position and has an accurate relative position, ensuring the subsequent forming quality.

[0095] The following optimizations or further descriptions can also be made.

[0096] For example, the left guide F24 and the right guide F27 are arranged in front of and behind each other, and the left slide F4 and the right slide F6 move forward and backward under the drive of the respective motors. For example, the left guide F24 and the right guide F27 are arranged in parallel to each other.

[0097] For example, the left slide F4 and the left motor F25 are connected by the left belt and pulley device F13, and the right slide F6 and the right motor F28 are connected by the right belt and pulley device F14. The left motor F25 and the right motor F28 are respectively servo motors.

[0098] In this embodiment, the lifting support F9 is installed on the transfer frame F8 relative to the lifting, and the lifting transmission driving device F15 is connected between the lifting support F9 and the transfer frame F8. The lifting transmission driving device F15 cooperates to drive the lifting support F9 to lift on the transfer frame F8. The lifting transmission driving device F15 can use a cylinder or a motor as a power source (which can be equipped with gear rack structure or screw nut structure or eccentric wheel connecting rod structure transmission connection). The lifting support F9 and the transfer frame F8 are also connected with the lifting guide rail pair F16. The lifting guide rail pair F16 cooperates with the guide to make the lifting support F9 run more stably on the transfer frame F8. The pick-and-place suction nozzle F10 includes a hard suction nozzle and / or a soft suction nozzle, which can not only meet all the suction on the paperboard, but also some suction nozzles can be adsorbed on the paperboard, and some suction nozzles can be adsorbed on the paperboard with glue. The subsequent release can be sucked by other components, such as the suction head at the bottom of the molding and pasting work station F2.

[0099] In addition, the material supply station F1 is also connected with the material incoming conveying device F17, which conveys the material F30 to the material supply station F1. For example, the material incoming conveying device F17 includes an incoming conveying belt. When the incoming conveying belt stays at the material supply station F1, the material on it is waiting to be transferred. The incoming conveying belt can be segmented and connected with the positioning machine.

[0100] For example, the horizontal movement transmission driving device F11 includes a horizontal movement force motor F18, a screw rod F19 and a screw nut F20. The horizontal movement force motor F18 is in transmission connection with the screw rod F19 to drive the screw rod F19 to rotate. The screw rod F19 is in transmission connection with the screw nut F20. The screw nut F20 and the horizontal movement force motor F18 are installed on the transfer frame F8 and the left rotating arm F5 or the right rotating arm F7. In the figure, the horizontal movement force motor F18 is installed on the transfer frame F8, and the screw rod F19 cooperates with the screw nut F20 to run. The transfer frame F8 is driven by the horizontal movement transmission driving device F11 to move left and right along the horizontal movement direction of the horizontal movement guide rail pair F12. The screw rod F19 is parallel to the horizontal movement direction of the horizontal movement guide rail pair F12. The horizontal movement force motor F18 is a servo motor.

[0101] In addition, the material position detection sensor can also be provided to obtain the relative position signal of the material (i.e., the material position relative deviation data). For example, the material feeding station F1 is further connected with a material feeding device F17, and a material position detection sensor is arranged above the material feeding device F17; or, the material position detection sensor is arranged above the material feeding station F1; or, the material feeding station F1 is further connected with a material feeding device F17, and the material feeding device F17 is connected with a positioning machine (which can be used to place the paperboard on the face paper for pasting), and the positioning machine comprises the material position detection sensor. The material position detection sensor comprises a visual sensor (such as a camera, for example, an industrial camera, etc.). The material position detection sensor is electrically connected with the left motor F25, the right motor F28, and the horizontal movement motor F18 of the horizontal movement transmission driving device F11. The material position detection sensor is electrically connected with a controller (such as a PLC controller or a computer, etc.). The controller is electrically connected with the left motor F25, the right motor F28, and the horizontal movement motor F18 of the horizontal movement transmission driving device F11. After the material position signal is collected, the controller feeds back the material position signal to the controller, and the controller controls the operation of the left motor F25, the right motor F28, and the horizontal movement motor F18.

[0102] In addition to setting the material position detection sensor to adopt the relative position signal of the material, the following methods can also be adopted: the front moving-to-position material detection sensor F21 is connected to the left slide plate F4 or the right slide plate F6 or the transfer frame F8 or the lifting support F9; the rotating-to-position material detection sensor F22 is connected to the transfer frame F8 or the lifting support F9; the horizontal moving-to-position material detection sensor F23 is connected to the transfer frame F8 or the lifting support F9; each sensor (the front moving-to-position material detection sensor F21, the rotating-to-position material detection sensor F22, and the horizontal moving-to-position material detection sensor F23) is electrically connected to the controller (such as a PLC controller or a computer, etc.), and the controller is electrically connected to the left motor F25, the right motor F28, and the horizontal moving force motor F18 of the horizontal moving transmission driving device F11; after the material position signal is collected by the sensor, it is fed back to the controller, and the controller cooperates with the operation of the left motor F25, the right motor F28, and the horizontal moving force motor F18 to run. When the left slide plate F4 and the right slide plate F6 move forward (usually synchronously moved by the left motor F25 and the right motor F28), the front side edge or the rear side edge of the material is detected by the front moving-to-position material detection sensor F21, at which time the left slide plate F4 and the right slide plate F6 can pause moving forward; then the left slide plate F4 and / or the right slide plate F6 move asynchronously forward and backward, so that the transfer frame F8 can rotate, until the front side edge or the rear side edge of the material is detected by the rotating-to-position material detection sensor F22, at which time the transfer frame F8 is rotated to the position, and the left slide plate F4 and / or the right slide plate F6 stop moving; then the transfer frame F8 is driven to move horizontally by the horizontal moving transmission driving device F11, until the left side or the right side edge of the material is detected by the horizontal moving-to-position material detection sensor F23; at this time, the entire transfer frame F8 and the lifting support F9, and the suction material nozzle F10 have been adjusted in position to obtain the material with a deviation in relative position, after the material is obtained, the transfer frame F8 moves horizontally back to the position on the left slide plate F4 and the right slide plate F6, the left slide plate F4 and the right slide plate F6 retreat back to the position of the forming and pasting work station F2, so that the material with a position deviation can be fine-tuned and corrected, and the relative position of the material at the forming and pasting work station F2 is relatively accurate.

[0103] The front moving-to-position material detection sensor F21, the rotating-to-position material detection sensor F22, and the horizontal moving-to-position material detection sensor F23 are respectively detected downward, which can smoothly detect the edge position of the material below. The installation positions of the rotating-to-position material detection sensor F22 and the horizontal moving-to-position material detection sensor F23 can also be adjusted according to the size specifications of different batches of materials.

[0104] The initial position of the detection point of the front-to-position material detection sensor F21 is arranged directly below the axis of the left vertical shaft F26 or the right vertical shaft F29, and the transfer frame F8 can rotate around the detection point of the front-to-position material detection sensor F21, i.e. around the left vertical shaft F26 or the right vertical shaft F29. During the rotation, the detection point of the front-to-position material detection sensor F21 will not move, which is relatively more accurate. Alternatively, the detection point of the front-to-position material detection sensor F21 is always arranged directly below the axis of the left vertical shaft F26 or the right vertical shaft F29, and the front-to-position material detection sensor F21 can be directly installed and connected on the left slide plate F4 or the right slide plate F6. The transfer frame F8 can rotate around the detection point of the front-to-position material detection sensor F21, i.e. around the left vertical shaft F26 or the right vertical shaft F29. During the rotation, the detection point of the front-to-position material detection sensor F21 will not move, which is relatively more accurate. Moreover, the detection point will not move during the horizontal movement, which is more stable.

[0105] For example, the horizontal-to-position material detection sensor F23, the rotation-to-position material detection sensor F22 and the front-to-position material detection sensor F21 each include a detection photoelectric eye (such as a laser photoelectric eye).

[0106] The front-to-position material detection sensor F21, the rotation-to-position material detection sensor F22 and the horizontal-to-position material detection sensor F23 each find the edge of the material to be detected. For example, the front-to-position material detection sensor F21 finds the front or rear edge of the material to be detected; the rotation-to-position material detection sensor F22 finds the front or rear edge of the material to be detected; and the horizontal-to-position material detection sensor F23 finds the left or right edge of the material to be detected. The detection points of the front-to-position material detection sensor F21, the rotation-to-position material detection sensor F22 and the horizontal-to-position material detection sensor F23 are generally arranged in a triangular shape.

[0107] Referring to the drawings, the triple board assembly mechanism of the carton forming equipment in the embodiment includes a triple board assembly station J1. The triple board assembly station J1 has a horizontal mold resting position one J2. The forming mold J22 is in a horizontal state and rests on the horizontal mold resting position one J2, i.e. the forming mold J22 can rest at the triple board assembly station J1 to wait for the assembly of the triple board J21.

[0108] One side (left / right side or front side) of the horizontal mold resting position one J2 of the triple board assembly station J1 has a triple board feeding position J3. The triple board feeding position J3 supplies the triple board J21. The triple board J21 refers to three paper boards connected to each other and divided by parallel slot lines.

[0109] The three-plate transfer assembly robot J4 is arranged between the three-plate feeding position J3 and the horizontal mold resting position one J2 of the three-plate assembly position J1, and the three-plate transfer assembly robot J4 is used to take away the three-plate J21 at the three-plate feeding position J3 and transfer it to the three-plate assembly position J1 for assembly.

[0110] The three-plate transfer assembly robot J4 includes a material transfer seat J5, a first side swing arm J6, and a second side swing arm J7. The material transfer seat J5 is located between the first side swing arm J6 and the second side swing arm J7. The first side swing arm J6 is provided with a first rotating shaft J8 between the material transfer seat J5, and the first side swing arm J6 can swing around the first rotating shaft J8 on the material transfer seat J5. The second side swing arm J7 is provided with a second rotating shaft J9 between the material transfer seat J5, and the second side swing arm J7 can swing around the second rotating shaft J9 on the material transfer seat J5. The material transfer seat J5 is further connected with a swing driving device J10, and the swing driving device J10 is in transmission connection with the first side swing arm J6 and the second side swing arm J7 respectively. The swing driving device J10 drives the first side swing arm J6 and the second side swing arm J7 to swing respectively. The first side swing arm J6 is provided with a first material suction nozzle J11, and the first material suction nozzle J11 swings with the first side swing arm J6. The first material suction nozzle J11 is used to suck and release the paperboard. The second side swing arm J7 is provided with a second material suction nozzle J12, and the second material suction nozzle J12 swings with the second side swing arm J7. The second material suction nozzle J12 is used to suck and release the paperboard. The first material suction nozzle J11 sucks the left paperboard of the three-plate J21, and the second material suction nozzle J12 sucks the right paperboard of the three-plate J21.

[0111] During operation, the three-plate transfer assembly robot J4 sucks the three-plate J21 at the three-plate feeding position J3 through the corresponding material suction nozzles (such as the first material suction nozzle J11 on the first side swing arm J6 and the second material suction nozzle J12 on the second side swing arm J7). The first side swing arm J6 and the second side swing arm J7 are in an unfolded state (such as a flattened state) to smoothly and stably suck the flat three-plate J21. After sucking, the three-plate transfer assembly robot J4 transfers the three-plate to the horizontal mold resting position one J2 of the three-plate assembly position J1, and can assemble the three-plate to the forming mold J22 running to the horizontal mold resting position one J2. When the three-plate is transferred to the horizontal mold resting position one J2, it is located above the forming mold J22. Then, the first side swing arm J6 and the second side swing arm J7 swing downward to assemble the three-plate J21 around the forming mold J22, complete the assembly, and the three-plate transfer assembly robot J4 resets for the next three-plate J21 assembly.

[0112] The triple plate assembly mechanism of the carton forming equipment can realize the transfer of the triple plate J21 to the horizontal mold resting position one J2 of the triple plate assembly station J1, can assemble the triple plate J21 to the forming mold J22 resting at the position, and can realize the transfer and assembly of the triple plate J21 by the cooperation of the triple plate transfer assembly robot J4, so as to cooperate with the subsequent carton forming, and the structure and station layout are reasonable and compact.

[0113] Compared with the previous mode of directly surrounding the four side wall paperboards (i.e. quadruple plate) of the corresponding carton on the forming mold J22, a new optional assembly forming mode is supplemented.

[0114] The following optimizations or further descriptions can be made on the basis of the above embodiments.

[0115] For example, the first suction nozzle J11 is located at the inner side of the first side swing arm J6, and the second suction nozzle J12 is located at the inner side of the second side swing arm J7, that is, when the first side swing arm J6 is swung upward to the position, the first suction nozzle J11 is directed to the inner side position downward, and when the first side swing arm J6 is swung downward to the position, the first suction nozzle J11 is directed to the inner side position inward (toward the forming mold J22); similarly, when the second side swing arm J7 is swung upward to the position, the second suction nozzle J12 is directed to the inner side position downward, and when the second side swing arm J7 is swung downward to the position, the second suction nozzle J12 is directed to the inner side position inward (toward the forming mold J22).

[0116] In addition, the lower side of the material transfer seat J5 is also provided with a material pressing surface J13, which can move with the material transfer seat J5. The material pressing surface J13 can cooperate with the (downward) pressure forming mold J22. After the material transfer seat J5 clamps the middle paperboard of the triple plate J21 by cooperating with the forming mold J22, the position of the paperboard is stabilized, the left and right paperboards of the triple plate J21 are turned over, the assembly of the triple plate J21 is more stable, and the surrounding assembly position of the triple plate J21 is relatively more accurate. The lower side of the material transfer seat J5 can be directly provided with the material pressing surface J13, and the material transfer seat J5 can be directly provided with a flat plate. The lower side of the material transfer seat J5 is also provided with a third suction nozzle J14, which can cooperate with the suction and release of the paperboard, cooperate with the suction and release of the middle paperboard of the triple plate J21, and can cooperate with the corresponding suction nozzles on the first side swing arm J6 and the second side swing arm to suction, release and transfer the triple plate J21. The third suction nozzle J14 can be arranged on the material pressing surface J13. The first suction nozzle J11, the second suction nozzle J12 and the third suction nozzle J14 can include structures such as suction holes or suction cups.

[0117] The material moving seat J5 is arranged back and forth between the horizontal mold staying position one J2 and the triplex board feeding position J3 of the triplex board assembly station J1. A material moving guide rail J23 can be arranged for the material moving seat J5 to move back and forth between them. A motor J24 or a pneumatic cylinder can be configured as a power source to drive the material moving seat J5 (on the material moving guide rail J23) to move back and forth. In the figure, a motor is used to drive the material moving seat J5 to move back and forth through a belt drive structure J25. In addition, the material moving seat J5 is also arranged to move up and down, and a motor or a pneumatic cylinder J26 can be configured to drive the material moving seat J5 to move up and down. In the figure, a moving plate J27 is arranged on the material moving guide rail J23, and the material moving seat J5 is installed and connected to the moving plate J27 through the pneumatic cylinder J26 to move up and down.

[0118] For example, the triplex board feeding position J3 can be arranged on the front side of the horizontal mold staying position one J2 of the triplex board assembly station J1. The front side of the horizontal mold staying position one J2 of the triplex board assembly station J1 is the direction in which the box bottom of the horizontal forming mold J22 faces.

[0119] The upper side of the horizontal mold staying position one J2 of the triplex board assembly station J1 has a material moving staying position J16 of the triplex board moving and assembling robot J4 (such as the material moving seat J5). The triplex board moving and assembling robot J4 moves the triplex board J21 (paperboard) to the material moving staying position J16 and to the upper side of the horizontal mold staying position one J2 (the forming mold J22). The triplex board J21 is more smoothly and stably enclosed in the forming mold J22, and is less likely to fall off after being enclosed. The triplex board J21 is also relatively stable when moving with the forming mold J22. The first side swing arm J6 and the second side swing arm J7 correspond to the left and right sides of the horizontal mold staying position one J2 of the triplex board assembly station J1, respectively.

[0120] When the first side swing arm J6 and the second side swing arm J7 are respectively swung upward to the position, a suction state is formed, the first suction nozzle J11 on the first side swing arm J6 and the second suction nozzle J12 on the second side swing arm J7 can cooperate to stably suck the corresponding paperboard part of the triplex board J21; the relative structure is more reasonable, and the triplex board J21 can be sucked and held when it is lowered. When the first side swing arm J6 and the second side swing arm J7 are respectively swung downward to the position, a holding state is formed, the first suction nozzle J11 on the first side swing arm J6 and the second suction nozzle J12 on the second side swing arm J7 can cooperate to fold the paperboard parts on both sides of the triplex board J21 downward and enclose them on the forming mold J22. When the first side swing arm J6 and the second side swing arm J7 are respectively swung downward to the position, the first suction nozzle J11 on the first side swing arm J6 cooperates with the left side of the forming mold J22, and the second suction nozzle J12 on the second side swing arm J7 cooperates with the right side of the forming mold J22. Among them, the front side of the forming mold J22 can be provided with a suction component (such as a suction hole or a suction disc, etc.), the upper side and / or the left and right sides of the forming mold J22 can be provided with a suction component (such as a suction hole or a suction disc, etc.), and the lower side of the forming mold J22 can be provided with a suction component (such as a suction hole or a suction disc, etc.), which can be set according to the needs, and the corresponding paper box part is sucked by the suction component to cooperate with the forming, and the paper box is released after completion.

[0121] The swing driving device J10 can select a cylinder or a motor as a power source, and the first side swing arm J6 and the second side swing arm J7 can share the power source or can be respectively provided with independent power sources. For example, the swing driving device J10 includes a first swing arm cylinder J17 and a second swing arm cylinder J18, and the swing driving device J10 is arranged on the upper side of the material moving seat J5; the first side swing arm J6 is transmissionally connected to the first rotating shaft J8, the first rotating shaft J8 is transmissionally connected with the first transmission arm J19, the first swing arm cylinder J17 is hinged to the material moving seat J5, the first swing arm cylinder J17 is transmissionally hinged with the first transmission arm J19, the first swing arm cylinder J17 drives the first transmission arm J19 to swing, thereby driving the first rotating shaft J8 to rotate back and forth (forward rotation and reverse rotation) on the material moving seat J5, and the first rotating shaft J8 can drive the first side swing arm J6 to swing; similarly, the second side swing arm J7 is transmissionally connected to the second rotating shaft J9, the second rotating shaft J9 is transmissionally connected with the second transmission arm J20, the second swing arm cylinder J18 is hinged to the material moving seat J5, the second swing arm cylinder J18 is transmissionally hinged with the second transmission arm J20, the second swing arm cylinder J18 drives the second transmission arm J20 to swing, thereby driving the second rotating shaft J9 to rotate back and forth (forward rotation and reverse rotation) on the material moving seat J5, and the second rotating shaft J9 can drive the second side swing arm J7 to swing.

[0122] In addition, the triple board feeding device J100 is also provided with a security buckle assembly device. After the security buckle assembly device assembles the buckle (such as a security buckle) on the triple board J21, the triple board feeding device supplies the triple board J21 to the triple board feeding position J3.

[0123] Referring to the drawings, the box body forming and pasting mechanism A6 in the embodiment includes a forming and pasting work station F2, and the forming and pasting work station F2 includes a horizontal mold resting position two E8. A horizontal forming mold J22 rests and cooperates at the horizontal mold resting position two E8 to perform box body forming and pasting. The horizontal forming mold J22 is a horizontally placed mold. The horizontal forming mold J22 cooperates with the pasting to form a corresponding horizontal paper box.

[0124] The horizontal mold resting position two E8 is provided below with a lifting and ejecting component H3. The lifting and ejecting component H3 can cooperate to hold and upwardly eject the material F30 to the horizontal forming mold J22 (as shown in the side view) resting at the horizontal mold resting position two E8.

[0125] The front side of the horizontal mold resting position two E8 is provided with a bottom supporting and turning component H4. The bottom supporting and turning component H4 can cooperate to hold the corresponding bottom plate of the box bottom and the corresponding part of the material F30 of the face paper and turn this part of the material F30 to the front side surface of the horizontal forming mold J22 (at the horizontal mold resting position two E8) by turning.

[0126] The left and right sides of the horizontal mold resting position two E8 are respectively provided with side pasting lifting components H5. The left and right side pasting lifting components H5 can paste the face paper on the paper boards on the left and right sides of the paper box on the left and right sides of the horizontal forming mold J22 (at the horizontal mold resting position two E8). The side pasting lifting components H5 press the face paper on the paper boards during the upward movement of the side pasting lifting components H5, and the side pasting lifting components H5 return to the original position.

[0127] The upper side of the horizontal mold resting position is also provided with an upper side face pasting mechanism H6. The upper side face pasting mechanism H6 can paste the face paper on the upper side surface of the paper board on the upper side of the paper box.

[0128] Before the forming and pasting, the horizontal forming mold J22 will stay at the horizontal mold staying position two E8 of the forming and pasting station F2, and the horizontal forming mold J22 has already placed the three-plate J21 in advance, and the three-plate J21 (including the upper side plate, the left side plate and the right side plate) encloses the upper side, the left side and the right side of the horizontal forming mold J22 (at the horizontal mold staying position two E8); the material F30 (i.e. the material F30 of the single-side wall paper board and the bottom plate and the whole face paper are pasted in advance) of the single-side wall paper board and the bottom plate combined with the whole face paper (one side of the face paper has been glued) is placed on the lifting and feeding component H3 and the bottom supporting and turning component H4, wherein the single-side wall paper board and the corresponding face paper part are located on the lifting and feeding component H3, the bottom plate and the corresponding face paper part are located on the bottom supporting and turning component H4, and the other part of the whole face paper will be pasted on the outside of the paper box. After the preparation work is completed, the box body forming and pasting mechanism A6 starts to work, the lifting and feeding component H3 rises, and the single-side wall paper board and the corresponding face paper are fed upward to the lower side of the horizontal forming mold J22 (at the horizontal mold staying position two E8); the bottom supporting and turning component H4 is turned towards the front side (corresponding to the bottom of the box) of the horizontal forming mold J22 (at the horizontal mold staying position two E8), and the bottom plate of the face paper is turned and fed to the front side of the horizontal forming mold J22 (at the horizontal mold staying position two E8). The left and right side pasting and lifting components H5 rise, and the face paper corresponding to the two sides of the paper box is pasted on the paper board of the paper box. Generally, the bottom supporting and turning is performed first, and then the left and right side pasting is performed. Finally, the upper side pasting mechanism H6 pastes the face paper corresponding to the upper side of the paper box on the paper board outside the upper side of the paper box, and the box body forming and pasting is completed. It can be used for the forming and pasting of the square box.

[0129] The box body forming and pasting mechanism A6 can form the box body by cooperating with the forming and pasting at the forming and pasting station F2, and the three-plate J21 is enclosed in the horizontal forming mold J22 in advance. The material F30 (i.e. the material F30 of the whole face paper and the single-side wall paper board and the bottom plate are pasted in advance) and the three-plate J21 enclosed in the horizontal forming mold J22 in advance can form the box body by cooperating with the forming and pasting at the forming and pasting station F2, which provides a new way of forming and pasting structure. The bottom plate pastes the face paper in advance, which avoids the deviation and the irregular edge pasting during the forming and pasting process. It supplements the previous four-plate method which has fewer choices.

[0130] The following optimizations or further explanations can be made based on the above embodiments.

[0131] For example, the front side of the horizontal mold stay position two E8 is also equipped with a box bottom three edge folding mechanism H7. After the cooperation of the bottom supporting and overturning part H4 is completed, the box bottom three edge folding mechanism H7 can cooperate to fold the edge of the side wall bottom area of the paper box corresponding to the paper. The edge of the paper corresponding to the bottom plate can be folded and covered on the paperboard of the side wall of the paper box, avoiding the exposure of the paperboard of the paper box at the bottom edge junction. The box bottom three edge folding mechanism H7 can correspond to the left side, the upper side, and the right side. The box bottom three edge folding mechanism H7 can use corresponding folding blocks or folding brushes or folding rollers and other corresponding folding components. For example, the box bottom three edge folding mechanism H7 includes a folding mounting frame E1, the folding mounting frame E1 is provided with an upper folding component E2, a left folding component E3 and a right folding component E4, and the folding mounting frame E1 is also provided with an upper folding transmission device E5, a left folding transmission device E6 and a right folding transmission device E7. The upper folding component E2 is connected with the upper folding transmission device E5, and the upper folding transmission device E5 cooperates to drive the upper folding component E2 to fold the upper side of the horizontal paper box bottom; the left folding component E3 is connected with the left folding transmission device E6, and the left folding transmission device E6 cooperates to drive the left folding component E3 to fold the left side of the box bottom; the right folding component E4 is connected with the right folding transmission device E7, and the right folding transmission device E7 cooperates to drive the right folding component E4 to fold the right side of the box bottom. Through the cooperation of the upper folding component E2, the left folding component E3 and the right folding component E4, the three edges (upper side, left side and right side) of the horizontal paper box bottom are folded, and the part of the paper corresponding to the three edge positions (i.e. upper side, left side and right side) of the box bottom is folded and covered (corner covering). The part of the paper corresponding to the three edge positions of the box bottom is connected and integrated with the paper bottom plate, and is pasted and cooperated by folding and covering. The upper folding component E2, the left folding component E3 and the right folding component E4 can share a power source or be respectively provided with a corresponding power source. The position of the side wall bottom area of the paper box for folding and covering can also be pre-processed by indentation or cutting to form a recess, which matches the thickness of the folded paper, and the subsequent pasting of the paper on the left side, upper side and rear side of the paper box is more flat, and there is almost no trace of three edge folding.

[0132] The three-edge folding mechanism of the bottom of the horizontal carton in the embodiment comprises a folding mounting frame E1, the folding mounting frame E1 is provided with an upper folding part E2, a left folding part E3 and a right folding part E4, and the folding mounting frame E1 is also provided with an upper folding transmission device E5, a left folding transmission device E6 and a right folding transmission device E7. The folding mounting frame E1 serves as a support structure for the installation of the upper folding part E2, the left folding part E3 and the right folding part E4, the upper folding transmission device E5, the left folding transmission device E6 and the right folding transmission device E7, etc. Among them: the upper folding part E2 is connected with the upper folding transmission device E5, and the upper folding transmission device E5 cooperates with the upper folding part E2 to fold the upper side of the bottom of the horizontal carton (hereinafter referred to as the bottom); the left folding part E3 is connected with the left folding transmission device E6, and the left folding transmission device E6 cooperates with the left folding part E3 to fold the left side of the bottom; the right folding part E4 is connected with the right folding transmission device E7, and the right folding transmission device E7 cooperates with the right folding part E4 to fold the right side of the bottom.

[0133] The three edges (upper side, left side and right side) of the bottom of the horizontal carton are folded by the cooperation of the upper folding part E2, the left folding part E3 and the right folding part E4, and the parts E27, E28 and E29 corresponding to the three edge positions (i.e. the upper side, the left side and the right side) of the bottom of the horizontal carton are folded and covered (corner covering). Among them, the parts E27, E28 and E29 corresponding to the three edge positions of the bottom of the horizontal carton can be connected with the paper bottom plate, and the folding and covering are cooperated by pasting.

[0134] The three-edge folding mechanism of the bottom of the horizontal carton can realize the three-edge folding of the bottom of the horizontal carton, meet the demand of three-edge folding at the same station, has high efficiency, can realize the folding demand in the forming of the carton, is more practical, can meet the demand of three-edge folding of the bottom before or after the lower side of the bottom is folded with the pasting paper of the bottom, and the upper folding part E2, the left folding part E3 and the right folding part E4 can be independently configured with a power source or can be cooperated with a linkage three-edge folding demand in a linkage mode (share a power source).

[0135] The following optimization or further description can be made.

[0136] Among them, the upper folding part E2, the left folding part E3 and the right folding part E4 can adopt a folding plate or a folding roller or a folding brush strip, etc.

[0137] For example, the upper folding part E2, the left folding part E3 and the right folding part E4 are arranged at the front side of the horizontal mold staying position E8, and the semi-finished carton is on the horizontal forming mold, when the horizontal forming mold is at the horizontal mold staying position E8, the upper folding part E2, the left folding part E3 and the right folding part E4 at the front side of the horizontal mold staying position E8 will cooperate to perform three-edge folding processing on the semi-finished carton on the horizontal forming mold, and the three-edge folding processing is performed at the same position (the horizontal mold staying position E8), and the structure is compact, wherein the upper folding part E2 is arranged at the upper side, the left folding part E3 is arranged at the left side, and the right folding part E4 is arranged at the right side.

[0138] For another example, the upper folding part E2 is arranged to move up and down and move forward and backward, and the upper folding action is cooperated by moving up and down and moving forward and backward, and the back-off is reset; the left folding part E3 is arranged to move left and right and move forward and backward, and the left folding action is cooperated by moving left and right and moving forward and backward, and the back-off is reset; the right folding part E4 is arranged to move left and right and move forward and backward, and the right folding action is cooperated by moving left and right and moving forward and backward, and the back-off is reset. Or as,

[0140] For example, the upper folding transmission device E5 includes a lifting moving seat E9, the upper folding part E2 is connected and installed on the lifting moving seat E9, and the lifting action of the lifting moving seat E9 will cooperate to drive the upper folding part E2 to move up and down; the left folding transmission device E6 includes a left moving seat E10, the left folding part E3 is connected and installed on the left moving seat E10, and the left moving seat E10 will cooperate to drive the left folding part E3 to move left and right; the right folding transmission device E7 includes a right moving seat E11, the right folding part E4 is connected and installed on the right moving seat E11, and the right moving seat E11 will cooperate to drive the left folding part E3 to move left and right.

[0141] The folding edge mounting rack E1 is provided with front and rear moving supports E12 which can move forward and backward on the folding edge mounting rack E1. The folding edge mounting rack E1 is connected with a folding edge front and rear moving driving device E13, and the folding edge front and rear moving driving device E13 is in transmission connection with the front and rear moving supports E12.
