Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of handbag processing, in particular, to a handbag threading method and a threading device. BACKGROUND

[0002] As a widely used packaging form, handbags occupy an important position in many industries such as retail, catering, gift, culture and art due to their convenience, practicality and good display. With the continuous growth of market demand, the production scale of handbags is expanding, and the requirements for production efficiency and quality are becoming increasingly stringent.

[0003] In the production process of handbags, it is essential to thread the handle into the reserved hole on the raw material plate and fix it. The quality of this process directly affects the performance and appearance quality of the handbag. In the traditional manual threading method, the worker needs to manually align the handle with the reserved hole, then thread and fix it. This not only consumes a lot of manpower and time, but also makes it difficult to ensure the consistency of the threading quality of each handbag, resulting in uneven product quality.

[0004] With the development of automation technology, some automatic threading devices have emerged. However, the existing automatic threading devices generally have the problem of complex steps. Usually, multiple complex actions and mechanisms are required to cooperate to complete the threading task. For example, in the threading process, the handle is first clamped, then moved to the bottom of the raw material plate through a multi-axis motion mechanism, and then adjusted to align with the reserved hole. A clamping part is also needed to pass through the reserved hole, clamp the handle, and then reset to achieve threading. The complex step design increases the manufacturing cost and maintenance difficulty of the equipment, and also reduces the production efficiency.

[0005] In summary, it is of great practical significance to develop an efficient and simple handbag threading method. It can promote the further development of the handbag production industry towards automation, improve the production efficiency and product quality of enterprises, and enhance the competitiveness of enterprises in the market.

[0008] For example, the method for threading a handle of a bag according to at least one embodiment of the present application further comprises: In the step S3, the two ends of the handle are clamped and swung simultaneously in the direction of the raw material plate, so that the handle is bent into a U shape and the two ends of the handle correspond to the positions of the two reserved holes respectively.

[0009] For example, the method for threading a handle of a bag according to at least one embodiment of the present application further comprises: In the step S3, a part of the end of the handle is reserved for threading into the reserved hole when the handle is clamped.

[0010] For example, the method for threading a handle of a bag according to at least one embodiment of the present application further comprises: In the step S3, the conveying direction of the raw material plate is parallel to the conveying direction of the handle, and the swing axis of the handle end when being swung is located in the conveying direction of the handle.

[0011] For example, the method for threading a handle of a bag according to at least one embodiment of the present application further comprises: In the step S4, the end of the handle is pushed into the reserved hole from the side where the handle is located and fixed to the raw material plate.

[0012] For example, the method for threading a handle of a bag according to at least one embodiment of the present application further comprises: In the step S4, after the end of the handle is passed through the reserved hole, the end of the handle is flattened on the raw material plate before being fixed.

[0013] For example, the method for threading a handle of a bag according to at least one embodiment of the present application further comprises: In the step S4, the flattening method of the end of the handle is pushing by a moving part or blowing by air flow.

[0014] For example, the method for threading a handle of a bag according to at least one embodiment of the present application further comprises: In the step S4, the fixing method of the end of the handle is at least one of adhesion and riveting.

[0015] The present application at least one embodiment further provides a bag handle threading device: The handbag threading device comprises a rack and a plate feeding mechanism, a tape feeding mechanism, a tape folding mechanism, a tape threading mechanism and a tape flattening mechanism arranged on the rack, the rack is provided with a tape threading station, the plate feeding mechanism is used for feeding a raw material plate to the tape threading station and suspending a reserved hole of the raw material plate, the tape feeding mechanism is used for feeding a tape to the tape threading station, the tape folding mechanism is used for clamping the tape and folding the tape into a U shape, the tape threading mechanism is used for threading an end portion of the tape into the reserved hole on the raw material plate, and the tape flattening mechanism is used for flattening and fixing the portion of the tape passing through the reserved hole to the raw material plate.

When the raw material plate is placed on the tape threading station, the reserved hole can be in a suspended state, so that there is enough space around the reserved hole for the threading operation.

[0018] The tape is usually placed in a roll on a roll-off device beside the equipment, and the tape is led out of the roll-off device and conveyed to the tape threading station.

[0024] The present application will be further described below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0025] In order to make the drawings simple, only the parts related to the application are shown in the drawings, and they do not represent the actual structure of the product. In addition, in order to make the drawings simple and easy to understand, in some drawings, only one of the parts with the same structure or function is shown, or only one of them is marked. In this document, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0026] In this document, it should be noted that unless otherwise explicitly specified and limited, the terms "mount", "connect", "connect" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] In the present application, unless otherwise explicitly specified and limited, "on" or "under" the first feature of the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the first feature is higher than the second feature in horizontal height. The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the first feature is lower than the second feature in horizontal height.

[0028] In the description of the present embodiment, the terms "up", "down", "left", "right" and other orientation or position relationships are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0029] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0030] As Figure 1 shown, it shows a handbag threading method in an embodiment of the present application, which comprises the following steps: Step S1: conveying the raw material plate with the edge having a reserved hole to the threading station, and making the reserved hole suspended.

[0031] Automated conveying equipment (such as conveyor belts or mechanical gripping devices) is used to transport raw material plates with pre-drilled holes on the edges to the threading station. When the raw material plate is placed at the threading station, the pre-drilled holes are suspended in the air, ensuring sufficient space around the holes for the threading operation.

[0032] Step S2: Convey the lifting belt to the belt threading station.

[0033] The lifting belt is usually placed in a roll on the side of the equipment by an unwinding device. The lifting belt is drawn out from the unwinding device and transported to the threading station. Guide rollers can be set up during the process to guide the direction of the lifting belt and ensure that the lifting belt does not twist or deviate during the transport process.

[0034] Step S3: Clamp the end of the lifting belt and swing it in the direction of the raw material plate so that the end of the lifting belt corresponds to the position of the reserved hole.

[0035] After clamping the end of the lifting belt with a clamping component (pneumatic or electric gripper), it swings under the drive of an external drive device, causing the clamping component and the lifting belt to swing towards the direction of the raw material plate. The angle and position of the swing ensure that the end of the lifting belt accurately corresponds to the position of the reserved hole on the raw material plate. One swing makes the end of the lifting belt correspond to the position of the reserved hole, which simplifies the process and reduces the operation time. Compared with the traditional method of adjusting the position of the lifting belt multiple times, this one-swing-to-position method greatly simplifies the operation steps.

[0036] Step S4: Pass the end of the lifting strap through the reserved hole and fix it to the raw material plate.

[0037] Using a strap-threading tool, such as a strap-threading needle or hook, thread the end of the carrying strap through the pre-drilled hole, and then secure the carrying strap to the material board. If using adhesive, pre-apply adhesive to the corresponding position on the material board. After threading the carrying strap through the pre-drilled hole, press the end of the carrying strap to ensure full contact with the adhesive and secure it. If using riveting, use a riveting device to thread rivets through the carrying strap and the material board for fixation. For sewing, use a sewing device to sew the carrying strap to the material board.

[0038] In summary, this method for threading straps on tote bags achieves efficient and simple operation through the rational design of each step. It effectively solves the problem of complicated steps in traditional strap threading methods, improves the production efficiency and product quality of tote bags, and enhances the competitiveness of enterprises in the market.

[0039] In some examples, the above steps are described in further detail. In step S3: By simultaneously clamping both ends of the strap and swinging synchronously, the symmetric clamping and swinging actions are used to make the strap naturally form a U shape during swinging, and the two ends can accurately correspond to the two reserved hole positions on the raw material plate respectively, fully utilizing the shape characteristics of the strap, realizing the preparation of threading the strap at both ends at one time, greatly improving the threading efficiency, and because it is operated simultaneously, the positions of the strap ends corresponding to the reserved holes are easier to keep symmetric and accurate, improving the quality and consistency of threading.

[0040] The clamping component does not clamp the end part of the strap when clamping the strap, but leaves a part of the strap that needs to be threaded into the reserved hole, providing the necessary conditions for subsequent threading into the reserved hole. In the present embodiment, the reserved length of the strap is preferably 1.5-3.5 cm.

[0041] The swinging axis of the clamping component is located in the conveying direction of the strap, and the clamping component swings around the axis located in the conveying direction of the strap. The strap swings around the axis as the center, and its swinging trajectory is more in line with the movement requirements of forming a U shape. This design makes the strap more naturally and conveniently form a U shape, reduces the twisting and deformation of the strap during swinging, and is beneficial to the accurate correspondence of the two ends of the strap to the reserved hole positions.

[0042] In step S4: After the strap corresponds to the reserved hole position, the end of the strap is pushed into the reserved hole from the side where the strap is located, avoiding the complex operation of the clamping component passing through the reserved hole from the other side, clamping the end of the strap and then resetting in the traditional method. Simplified threading operation reduces the operation steps and time, and improves the production efficiency. The side where the strap is located can be the upper side or the lower side of the raw material plate. In the present embodiment, the side where the strap is located is the lower side of the raw material plate.

[0043] After threading the end of the strap through the reserved hole, the end of the strap is flattened on the raw material plate before being fixed. If a movable component is used to flatten, when the strap is pushed up from the bottom to the reserved hole, a movable component can be provided above the raw material plate and moved parallel to the surface of the raw material plate to flatten the end of the strap. If an air flow is used to flatten, a gas nozzle is provided beside the raw material plate above, the gas nozzle is connected to a gas source, and the end of the strap is blown flat on the raw material plate by controlling the size of the air flow. After the end of the strap is flattened, it is fixed by bonding or riveting. The end of the strap may be bent or uneven after threading through the reserved hole. Flattening operation can make the end of the strap better fit the raw material plate, improve the firmness and aesthetics of the fixed.

[0044] Choose the appropriate fixing method based on the material of the tote bag, its usage scenario, and customer requirements. If the tote bag is used for packaging lightweight items and has high aesthetic requirements, adhesive bonding may be chosen. Apply special adhesive to the corresponding position on the raw material board, pass the end of the handle through the pre-drilled hole and smooth it out, then apply appropriate pressure using a pressure device to ensure full contact between the handle end and the adhesive. After curing, the fixing is complete. For tote bags that need to withstand greater weight or have higher requirements for sturdiness, riveting is used. Use a riveting device to pass rivets through the handle and the raw material board, fixing the handle to the raw material board. Choosing the appropriate fixing method or a combination of fixing methods according to actual needs can fully utilize the advantages of various fixing methods and ensure that the connection between the handle and the raw material board meets the requirements of different products.

[0045] Preferably, this embodiment first uses adhesive bonding as initial fixation, and then further strengthens the fixation effect through riveting. In actual production, the overall tote bag processing equipment often includes multiple workstations, such as the strap threading workstation and the subsequent riveting workstation. In this embodiment, the strap threading and smoothing actions can be performed at the strap threading workstation, thereby achieving adhesion between the end of the handle and the pre-applied adhesive layer at the strap threading workstation. With this setup, firstly, the composite fixation method of adhesive bonding and riveting provides high fixation strength, which can greatly improve the load-bearing capacity of the tote bag; secondly, although a composite fixation method is used, the adhesive work can be achieved during the smoothing action at the strap threading workstation, so no additional workstation is needed; furthermore, pre-adheding the end of the handle to the tote bag ensures that the end of the handle will not drift or shift during the subsequent workstation flow of the tote bag, thereby achieving a pre-fixation effect and ensuring the accuracy of the subsequent riveting position and the riveting quality.

[0046] like Figures 2-9 As shown, a tote bag strap-threading device according to an embodiment of the present invention is illustrated, including a frame 1 and a plate feeding mechanism 2, a strap feeding mechanism 3, a strap folding mechanism 4, a strap threading mechanism 5, and a smoothing mechanism 6 disposed on the frame 1.

[0047] The feeding mechanism 2 can be a conventional conveyor belt or a mechanical gripping mechanism to transport the raw material plate to the threading station and suspend the reserved holes of the raw material plate to create space for subsequent threading operations and avoid obstruction during threading.

[0048] In the belt feeding mechanism 3, the unwinding device is used to place the belt roll. After the belt is led out from the unwinding device, it passes through the guide roller to ensure that the belt remains straight during the conveying process and does not twist or deviate, so as to ensure that the belt can be accurately conveyed to the belt threading station.

[0049] The folding belt mechanism 4 comprises two sets of symmetrically arranged clamping components and a swing driving device. The clamping components can clamp the handle strap. When the handle strap is conveyed to the position, the two clamping components clamp the two ends of the handle strap at the same time. The swing driving device drives the clamping components to swing, so as to fold the handle strap into a U shape, so as to prepare for the subsequent threading, and help the two ends of the handle strap to accurately correspond to the reserved hole of the raw material plate.

[0050] The threading mechanism 5 is located on the side where the handle strap of the raw material plate is located, and is preferably located on the lower side of the raw material plate in the embodiment. The threading mechanism 5 mainly comprises a pushing device. The pushing device can be an electric push rod, a pneumatic push rod or a hydraulic push rod. The end of the pushing device is provided with a flat plate-shaped push head, so as to better contact and push the end of the handle strap. When the handle strap is folded into a U shape and corresponds to the reserved hole position, the pushing device is started to push the end of the handle strap into the reserved hole. The end of the handle strap is pushed from the side where the handle strap is located, avoiding the complicated operation of threading from the other side and resetting, and simplifying the operation.

[0051] The smoothing mechanism 6 can adopt two modes of a movable push plate or a jet nozzle. If the movable push plate mode is adopted, a movable push plate is arranged above the raw material plate and is driven by a motor or a cylinder. When the end of the handle strap passes through the reserved hole, the push plate moves to smooth the part of the handle strap passing through the reserved hole to the raw material plate. If the jet nozzle mode is adopted, a jet nozzle is arranged above the raw material plate and is connected to a gas source. The jet nozzle blows the part of the handle strap passing through the reserved hole to the raw material plate. Both modes can make the handle strap better adhere to the raw material plate, improve the fixing effect and the aesthetic degree.

[0052] In summary, through the cooperative work of each mechanism, the handle bag threading device realizes the automatic and efficient operation of the handle strap from conveying, folding, threading to smoothing, solves the problem of complicated steps in the traditional threading mode, and improves the production efficiency and product quality.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
