Description

Technical Field

[0001] This invention relates to the field of paper bag processing technology, specifically to a header card attaching mechanism and a header card attaching method. Background Technology

[0002] Typically, bag-making machines attach header tags to the inside of the bag opening to increase bag strength, facilitate lifting and hanging, and prevent tearing. As the packaging industry develops towards higher speeds, automation, and precision, increasingly higher demands are being placed on the efficiency and accuracy of the header tag attaching process.

[0003] In related technologies, the card-attaching process is generally completed by a cam-linkage intermittent card-attaching mechanism or a servo-driven rotary card-attaching mechanism. However, the card-attaching mechanisms in these technologies suffer from numerous movements and low efficiency.

[0004] The above statements are for the purpose of providing background information in relation to this application only and do not necessarily constitute prior art. Summary of the Invention

[0005] This invention provides a card-attaching mechanism and method to solve the problems of excessive actions and low efficiency in related technologies.

[0006] The present invention provides a card-attaching mechanism, comprising: a gear ring, a connecting plate, N planetary gears, and a suction nozzle group corresponding to each planetary gear, where N is an integer greater than or equal to 3; the connecting plate is connected to a driving device for transmission, the planetary gears are rotatably mounted on the connecting plate via gear shafts, and the planetary gears mesh with the internal teeth of the gear ring; the suction nozzle groups are disposed on the corresponding gear shafts and are used to adsorb or release the card; when the driving device drives the connecting plate to rotate, the planetary gears revolve around the center of the gear ring and rotate around their own axes, so that when the planetary gears revolve to the card-removing position, the suction nozzle groups face the card and adsorb the card, and when the planetary gears revolve to the card-attaching position, the suction nozzle groups face the card-attaching position of the paper and release the card.

[0007] Beneficial effects: In the above-mentioned card-attaching mechanism, when the drive device drives the connecting plate to rotate, the gear shaft mounted on the connecting plate drives the planetary gear to mesh with the internal teeth of the gear ring. The planetary gear revolves around the center of the gear ring while rotating on its own axis. When the planetary gear revolves to the card-removing position, the suction nozzle assembly is exactly facing the card, and the suction nozzle assembly adsorbs the card to complete the card removal. The planetary gear continues to revolve, and the suction nozzle assembly maintains the adsorption state to move the card to the card-attaching position. When the planetary gear revolves to the card-attaching position, the rotation of the planetary gear makes the suction nozzle assembly exactly facing the card-attaching position of the paper, and the suction nozzle assembly releases the card, completing a single card-attaching action. Therefore, the actions of picking up, moving, and sticking cards are completed by the same planetary gear meshing mechanism in continuous rotation, with no pauses or waiting between actions. The transmission chain is short and the structure is compact, which shortens the time required for sticking a card. At the same time, the orientation of the card suction and release is determined by the precise meshing of the gear ring and the planetary gear, which has high positioning accuracy and good consistency. The cumulative error caused by the cooperation of multiple mechanisms is reduced, the risk of failure is reduced, and the efficiency and reliability of card sticking are improved.

[0008] In one optional embodiment, the card attaching mechanism further includes a feeding rack, which is disposed at the card taking position and is used to store the card.

[0009] In one optional embodiment, the nozzle attachment mechanism further includes a pneumatic slip ring, which is installed at the rotation center of the connecting plate. The air passage of the nozzle assembly is connected to the air source through the pneumatic slip ring to maintain the air passage connection of the nozzle assembly during the rotation of the connecting plate.

[0010] In one optional embodiment, the driving device is a servo motor, the motor shaft of which is connected to the connecting plate to drive the connecting plate to rotate around the center of the gear ring.

[0011] In one optional embodiment, the card-attaching position is located at the bottom of the gear ring. When the planetary gear revolves to the bottom of the gear ring, the rotation of the planetary gear causes the suction nozzle assembly to face the card-attaching position of the paper, and the suction nozzle assembly releases air pressure to attach the card to the paper.

[0012] In one optional embodiment, the nozzle assembly is provided in multiple sets, the multiple sets of nozzle assemblies are distributed along the axial direction of the gear shaft, and each set of nozzle assemblies includes multiple nozzles distributed along the axial direction of the gear shaft.

[0013] In one alternative embodiment, the gear shaft is connected to the connecting plate via a bearing.

[0014] In one optional implementation, N planetary gears are evenly distributed along the circumference of the gear ring, and the connecting plate completes N card-attaching actions in one rotation.

[0015] In one optional implementation, N=3, and the connecting plate completes three card-attaching actions in one rotation; In one optional implementation, N=4, and the connecting plate completes four card-attaching actions in one rotation; In one optional implementation, N=5, and the connecting plate completes five card-attaching actions in one rotation; In one alternative implementation, N=6, and the connecting plate completes six card-attaching actions in one rotation.

[0016] The present invention also provides a method for attaching a header card, comprising the following steps: S1. The drive unit drives the connecting plate to rotate, and the planetary gear meshes with the gear ring inside the gear ring, revolves around the center of the gear ring and rotates around the gear shaft. S2. When the planetary gears revolve to the card-removing position, the nozzle assembly faces the head card and inhales to adsorb the head card. S3. The planetary gears continue to revolve, the nozzle assembly maintains suction, and the head card is moved to the card-attaching position on the paper; S4. When the planetary gears revolve to the card-sticking position, the suction nozzle assembly faces the card-sticking position on the paper, releases air pressure, and the card is attached to the designated position on the paper, completing a single card-sticking action. Repeat steps S1-S4 in a cyclical manner.

[0017] Beneficial effects: In the above card-attaching method, the actions of card picking, card moving, and card attaching are completed sequentially with the continuous revolution and rotation of the planetary gears, without pauses or waiting between steps, thus shortening the time required for a single card attachment; the orientation of card suction and card placement is determined by the precise meshing relationship between the gear ring and the planetary gears, resulting in high card-attaching positioning accuracy and good consistency; multiple planetary gears sequentially pick up and attach cards, and N card-attaching actions can be completed with one rotation of the connecting plate, improving card-attaching efficiency and reliability.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The following is combined Figures 1 to 13 The embodiments of the present invention will be described in detail below.

[0023] The header card attaching mechanism disclosed in the embodiments of this application can be applied to, but is not limited to, bag making equipment, specifically to the header card attaching process 200 before paper bags are rolled into tubes. Of course, this header card attaching mechanism can also be applied to other equipment that requires transferring and placing sheet-shaped cards at a target location, and this document does not limit it.

[0024] This application provides a card attaching mechanism 200, which includes: a gear ring 10, a connecting plate 20, N planetary gears 30, and suction nozzle groups 50 corresponding to the planetary gears 30, where N is an integer greater than or equal to 3; the connecting plate 20 is connected to a driving device 60, the planetary gears 30 are rotatably mounted on the connecting plate 20 via gear shafts 40, and the planetary gears 30 mesh with the internal teeth of the gear ring 10; the suction nozzle groups 50 are disposed on the corresponding gear shafts 40 and are used to absorb or release the card attaching mechanism 200; when the driving device 60 drives the connecting plate 20 to rotate, the planetary gears 30 revolve around the center of the gear ring 10 and rotate around the gear shafts 40, so that when the planetary gears 30 revolve to the card picking position, the suction nozzle groups 50 face the card attaching mechanism 200 and absorb the card attaching mechanism 200, and when the planetary gears 30 revolve to the card attaching position, the suction nozzle groups 50 face the card attaching position of the paper 100 and release the card attaching mechanism 200.

[0025] The gear ring 10 is an annular gear component with internal teeth formed on its inner circumferential surface, i.e., the tooth profile facing the center of the gear ring 10. The gear ring 10 is fixedly mounted on the frame and remains stationary during the operation of the mechanism, providing a fixed meshing reference for the meshing motion of the planetary gear 30. The material of the gear ring 10 may be, but is not limited to, alloy steel or surface-hardened carbon steel to improve the wear resistance of the tooth surface.

[0026] Planetary gear 30 is a cylindrical gear with external teeth on its outer circumference that are adapted to the internal teeth of gear ring 10. Planetary gear 30 meshes with the internal teeth of gear ring 10 to form an internal meshing gear pair.

[0027] The radius ratio of the gear ring 10 to the planetary gear 30 is 1:N, where N is an integer greater than or equal to 3, such as 3, 4, 5, or 6. This radius ratio determines the rotation angle of the planetary gear 30 during one revolution, thus causing the nozzle assembly 50 mounted on the planetary gear 30 to present a specific orientation at a specific revolution position.

[0028] The connecting plate 20 is a plate-shaped component, which may be, but is not limited to, a disc-shaped, strip-shaped, or irregularly shaped plate. The connecting plate 20 is connected to the drive device 60 for transmission. The rotational motion output by the drive device 60 is transmitted to the connecting plate 20, causing the connecting plate 20 to rotate around the center of the gear ring 10. The connecting plate 20 serves as a load-bearing component for the planetary gear 30, driving the planetary gear 30 to revolve around the center of the gear ring 10.

[0029] Planetary gear 30 is rotatably mounted on connecting plate 20 via gear shaft 40, meaning that planetary gear 30 can rotate relative to connecting plate 20 about the axis of gear shaft 40. The axis of gear shaft 40 is parallel to the central axis of gear ring 10.

[0030] The nozzle assembly 50 is set on the corresponding gear shaft 40 and corresponds one-to-one with the planetary gear 30, that is, each planetary gear 30 is provided with at least one nozzle assembly 50.

[0031] The nozzle assembly 50 includes a nozzle, which is a pneumatic component that uses negative pressure to adsorb sheet-like materials. The nozzle assembly 50 is connected to an air source. When the nozzle assembly 50 is vented to create negative pressure, the nozzle adsorbs the head clip 200; when the nozzle assembly 50 releases the air pressure, the head clip 200 disengages from the nozzle assembly 50. Since the nozzle assembly 50 is located on the gear shaft 40, the nozzle assembly 50 revolves around the center of the gear ring 10 along with the planetary gear 30, and simultaneously rotates on its own axis along with the planetary gear 30, thus presenting different orientations at different revolution positions.

[0032] The take-up position is the revolution position of the planetary gear 30 when the suction nozzle assembly 50 performs the suction head clamping 200 action, such as the top or side area of ​​the gear ring 10 or the position near the feed rack 70.

[0033] The contact point is the revolution position of the planetary gear 30 when the nozzle assembly 50 performs the action of releasing the head clip 200, such as the bottom area of ​​the gear ring 10.

[0034] Header card 200 is a sheet-like card, which can be, but is not limited to, a paper or plastic sheet, used to attach to the inside of the bag opening to increase the bag's strength. Paper 100 is the raw material for bag making, and its surface has pre-drilled holes for attaching the card.

[0035] The drive device 60 is a power device that outputs rotary motion, which may be, but is not limited to, an electric motor. The drive device 60 is connected to the connecting plate 20 in a transmission manner to drive the connecting plate 20 to rotate around the center of the gear ring 10.

[0036] When the drive device 60 drives the connecting plate 20 to rotate, the connecting plate 20 drives the gear shaft 40, which in turn drives the planetary gear 30 to mesh with the internal teeth of the gear ring 10. The planetary gear 30 revolves around the center of the gear ring 10 and rotates around the gear shaft 40. When the planetary gear 30 revolves to the card-removing position, the suction nozzle assembly 50 is exactly facing the card head 200. The suction nozzle assembly 50 sucks in air to adsorb the card head 200, completing the card removal. The planetary gear 30 continues to revolve, and the suction nozzle assembly 50 continues to suck in air, moving the card head 200 to the card-attaching position on the paper 100. When the planetary gear 30 revolves to the card-attaching position, the rotation of the planetary gear 30 makes the suction nozzle assembly 50 exactly facing the card-attaching position on the paper 100. The suction nozzle assembly 50 releases air pressure, and the card head 200 is attached to the designated position on the paper 100, completing a single card-attaching action.

[0037] Therefore, the actions of picking up, moving, and sticking cards are completed by the same planetary gear 30 meshing mechanism in continuous rotation, with no pauses or waiting between actions. The transmission chain is short and the structure is compact, which shortens the time required for sticking a card. At the same time, the orientation of card suction and release is determined by the precise meshing of the gear ring 10 and the planetary gear 30, which has high positioning accuracy and good consistency. The cumulative error caused by the cooperation of multiple mechanisms is reduced, the risk of failure is reduced, the transmission is continuous, smooth and low noise, and the efficiency and reliability of card sticking are improved.

[0038] In some embodiments, the header card 200 attaching mechanism further includes a feeding rack 70, which is disposed at the card retrieval position and is used to store the header card 200.

[0039] The feeding rack 70 is a frame component for stacking and storing head cards 200, and may be, but is not limited to, a hopper structure with a receiving slot. The feeding rack 70 is located at the card-retrieving position, with its discharge side facing the path through which the suction nozzle assembly 50 rotates. When the planetary gear 30 revolves to the card-retrieving position, the suction nozzle assembly 50 abuts against the head cards 200 on the feeding rack 70 and draws air, sucking out the outermost head card 200 from the feeding rack 70.

[0040] By setting the feeding rack 70 at the card retrieval position, the storage position of the head card 200 corresponds to the card retrieval position of the suction nozzle assembly 50. When the suction nozzle assembly 50 revolves to the card retrieval position, it can directly retrieve the head card 200 from the feeding rack 70. The card retrieval action and the revolving motion are naturally connected, without the need for an additional card feeding mechanism. The mechanism structure is further compacted, the continuity and reliability of card retrieval are improved, and the card application efficiency is improved accordingly.

[0041] In some embodiments, the nozzle 200 mechanism further includes a pneumatic slip ring 80, which is installed at the rotation center of the connecting plate 20. The air passage of the nozzle assembly 50 is connected to the air source through the pneumatic slip ring 80 to maintain the air passage connection of the nozzle assembly 50 during the rotation of the connecting plate 20.

[0042] The pneumatic slip ring 80 is a rotary joint used to transfer a gas medium between two relatively rotating components. It may include, but is not limited to, a fixed part and a rotating part. The fixed part is connected to the air source, and the rotating part rotates with the connecting plate 20 and is connected to the nozzle assembly 50 via an air passage. The pneumatic slip ring 80 is installed at the rotation center of the connecting plate 20, that is, the rotation axis of the pneumatic slip ring 80 coincides with the rotation axis of the connecting plate 20.

[0043] When the connecting plate 20 rotates continuously, if the air tube of the nozzle assembly 50 is directly connected to the fixed air source, the air tube will become entangled as the connecting plate 20 rotates. By setting a pneumatic slip ring 80, the air path between the air source and the nozzle assembly 50 is transmitted through the fixed part and the rotating part of the pneumatic slip ring 80. During the rotation of the connecting plate 20, the air path connection of the nozzle assembly 50 is maintained, the entanglement of the air tube is reduced, the stability of the adsorption air pressure is improved, the positioning of the head card 200 is stable and the offset is reduced during the transfer, and the continuity and reliability of the card application are improved.

[0044] In some embodiments, the drive device 60 is a servo motor, and the motor shaft 61 of the servo motor is connected to the connecting plate 20 to drive the connecting plate 20 to rotate around the center of the gear ring 10.

[0045] A servo motor is a power device that can precisely control speed and angle. The motor shaft 61 is the output shaft of the servo motor. The motor shaft 61 is connected to the connecting plate 20. For example, the motor shaft 61 can pass through the center of the gear ring 10 and be fixedly connected to the connecting plate 20, so that the rotational motion output by the servo motor can be directly transmitted to the connecting plate 20.

[0046] The servo motor has stable speed and high control precision. The rotation speed of the connecting plate 20 can be adjusted according to the production cycle, and the card-attaching speed can be adjusted flexibly and conveniently. At the same time, the motor shaft 61 is directly connected to the connecting plate 20, resulting in a short transmission chain, smooth transmission and low noise. The orientation accuracy of card suction and card placement is further improved, and the card-attaching efficiency and consistency are improved.

[0047] In some embodiments, the card-attaching position is located at the bottom of the gear ring 10. When the planetary gear 30 revolves to the bottom of the gear ring 10, the rotation of the planetary gear 30 causes the suction nozzle assembly 50 to face the card-attaching position of the paper 100, and the suction nozzle assembly 50 releases air pressure to attach the card 200 to the paper 100.

[0048] The bottom of the gear ring 10 refers to the lower part of the gear ring 10 in the vertical direction. The paper 100 attaching card 200 station can be set below the gear ring 10, opposite to the bottom of the gear ring 10. When the planetary gear 30 revolves to the bottom of the gear ring 10, the suction nozzle assembly 50 faces downward under the action of its rotation, that is, towards the attaching position of the paper 100.

[0049] The head card 200 is attached to the paper 100 at the bottom of the toothed ring 10. On the one hand, after the head card 200 is released, it can fall to the attachment position of the paper 100 by its own gravity, making the attachment of the head card 200 and the paper 100 smoother and reducing the possibility of the head card 200 drifting off course. On the other hand, the conveying path of the paper 100 can be arranged horizontally below the toothed ring 10, making the overall layout of the mechanism compact and the connection between the attachment position and the conveying of the paper 100 natural, thus improving the attachment accuracy and reliability.

[0050] In some embodiments, multiple sets of nozzle assemblies 50 are provided, and the multiple sets of nozzle assemblies 50 are distributed along the axial direction of the gear shaft 40. Each set of nozzle assemblies 50 includes multiple nozzles distributed along the axial direction of the gear shaft 40.

[0051] The axial direction of the gear shaft 40 refers to the direction in which the axis of the gear shaft 40 extends. Multiple sets of suction nozzles 50 are distributed at intervals along the axial direction of the gear shaft 40, and multiple suction nozzles in each set of suction nozzles 50 are distributed along the axial direction of the gear shaft 40, so that multiple suction nozzles form multiple suction points in the width direction of the head clip 200.

[0052] Since the head card 200 is a sheet material, a single adsorption point can easily cause it to skew during transport. By distributing multiple suction nozzles along the gear shaft 40 to form multiple adsorption points, the adsorption area of ​​the head card 200 by the nozzle group 50 is increased and the adsorption positions are more dispersed. This results in stable positioning and reduced skew during the transport of the head card 200, further improving the orientation accuracy of card suction and placement, and enhancing card adhesion consistency.

[0053] In some embodiments, the gear shaft 40 is connected to the connecting plate 20 via a bearing.

[0054] The bearing may be, but is not limited to, a rolling bearing. The outer ring of the bearing is mounted on the connecting plate 20, and the inner ring of the bearing mates with the gear shaft 40, allowing the gear shaft 40 to rotate smoothly relative to the connecting plate 20.

[0055] With the bearing connection, the rotational friction between the gear shaft 40 and the connecting plate 20 is reduced, the rotation of the planetary gear 30 is more flexible and stable, the wear and noise of the mechanism during high-speed operation are reduced, the transmission is continuous, smooth and low noise, and the card-attaching efficiency is improved.

[0056] In some embodiments, N planetary gears 30 are evenly distributed along the circumference of the gear ring 10, and the connecting plate 20 completes N card-attaching actions by rotating one revolution.

[0057] N planetary gears 30 are evenly distributed along the circumference of the gear ring 10, meaning that the circumferential spacing between any two adjacent planetary gears 30 is equal, i.e., the spacing angle is 360° / N. Thus, when one planetary gear 30 revolves to the card-attaching position and completes the card-attaching action, the adjacent planetary gear 30 revolves to the card-removing position and retrieves the first card 200, continuing the cyclical motion. As the connecting plate 20 rotates one revolution, the N planetary gears 30 sequentially pass through the card-attaching positions, completing N card-attaching actions.

[0058] For example, such as Figures 1-6 N=3, the radius ratio of the gear ring 10 to the planetary gear 30 is 1:3, the three planetary gears 30 are evenly distributed along the circumference of the gear ring 10, and the connecting plate 20 completes three card-attaching actions by rotating one revolution.

[0059] For example, such as Figure 7 and Figure 8 N=4, the radius ratio of the gear ring 10 to the planetary gear 30 is 1:4, the four planetary gears 30 are evenly distributed along the circumference of the gear ring 10, and the connecting plate 20 completes four card-attaching actions by rotating one revolution.

[0060] For example, such as Figure 9 and Figure 10 N=5, the radius ratio of the gear ring 10 to the planetary gear 30 is 1:5, the five planetary gears 30 are evenly distributed along the circumference of the gear ring 10, and the connecting plate 20 completes five card-attaching actions by rotating one revolution.

[0061] For example, such as Figures 11 to 12 N=6, the radius ratio of the gear ring 10 to the planetary gear 30 is 1:6, the six planetary gears 30 are evenly distributed along the circumference of the gear ring 10, and the connecting plate 20 completes six card-attaching actions by rotating one revolution.

[0062] Multiple planetary gears 30 are evenly distributed around the gear ring 10. The suction nozzles 50 on each planetary gear 30 pick up cards from different positions and apply cards at the same position. While one planetary gear 30 completes the application of a card, another planetary gear 30 picks up the first card 200. The card picking and application actions are continuous and cyclical without interruption. Furthermore, by changing the radius ratio of the gear ring 10 to the planetary gears 30 and the number of planetary gears 30, the number of card applications per unit time can be adjusted without changing the speed of the drive device 60. The method of increasing the card application speed is simple and flexible, the high-speed performance of the mechanism is improved, and the card application efficiency is increased.

[0063] Embodiments of this application also provide a method for attaching a header card 200, employing the header card 200 mechanism of any of the above embodiments, combined with... Figures 1 to 6 , Figure 13 It includes the following steps: S1. The drive device 60 drives the connecting plate 20 to rotate. The planetary gear 30 meshes with the gear ring 10 inside the gear ring 10, revolves around the center of the gear ring 10 and rotates around the gear shaft 40.

[0064] For example, when the servo motor rotates, the motor shaft 61 drives the connecting plate 20 to rotate, thereby causing the gear shaft 40 to drive the planetary gear 30 to mesh with the gear ring 10. The planetary gear 30 revolves around the center of the gear ring 10 and rotates around the gear shaft 40. At this time, the nozzle assembly 50 is about to approach the head clip 200.

[0065] S2. When the planetary gear 30 revolves to the card-removing position, the nozzle assembly 50 faces the head card 200 and inhales to adsorb the head card 200.

[0066] For example, the planetary gear 30 rotates with the gear shaft 40 to the head clamp 200 waiting area of ​​the feed rack 70, that is, to take the clamping position. The suction nozzle of the suction nozzle group 50 touches the head clamp 200, and at this time the suction nozzle sucks air to hold the head clamp 200.

[0067] S3, planetary gear 30 continues to revolve, nozzle assembly 50 maintains suction, and head card 200 is moved to the card-attaching position of paper 100.

[0068] For example, the head clip 200 continues to be held by the nozzle assembly 50 as the planetary gear 30 and gear shaft 40 move downward.

[0069] S4. When the planetary gear 30 revolves to the card-sticking position, the suction nozzle assembly 50 faces the card-sticking position of the paper 100, releases air pressure, and the head card 200 is attached to the designated position of the paper 100, completing a single card-sticking action.

[0070] For example, the planetary gear 30 and gear shaft 40 continue to rotate, driving the nozzle assembly 50 to accurately move the head card 200 to the reserved head card 200 position on the paper 100; the suction continues, the head card 200 is positioned stably and the offset is reduced; when the planetary gear 30 revolves to the card-attaching position at the bottom of the gear ring 10, the nozzle assembly 50 faces the card-attaching position on the paper 100, and then the nozzle releases air pressure, the head card 200 is attached to the designated position, completing a single head card 200 placement action.

[0071] Repeat steps S1-S4 in a cyclical manner.

[0072] In the above-mentioned card-attaching method 200, the card-taking, card-moving, and card-attaching actions are completed sequentially with the continuous revolution and rotation of the planetary gear 30, without pauses or waiting between steps, thus shortening the time required for a single card-attaching operation. The orientation of card suction and card release is determined by the precise meshing relationship between the gear ring 10 and the planetary gear 30, resulting in high card-attaching positioning accuracy and good consistency. Multiple planetary gears 30 sequentially cycle through card taking and attaching, and the connecting plate 20 can complete N card-attaching actions in one rotation, thereby improving card-attaching efficiency and reliability.

[0073] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
