Description

Technical Field

[0001] This utility model relates to sewing technology, and more particularly to a handle sewing device for a tote bag. Background Technology

[0002] A tote bag is a simple and portable bag, usually made of materials such as paper, non-woven fabric, nylon, and canvas, used to hold items, carry gifts, or as a fashion accessory.

[0003] Currently, the handles on shopping bags are difficult to shape due to the material, making them hard to position when bending and sewing. Therefore, most of them are still sewn manually or semi-automatically, which not only results in low production efficiency, but also makes it easy for semi-automatic sewing devices to injure the operator's hands. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a handle sewing device for tote bags, which can automatically sew the handle strap onto the bag body, resulting in high production efficiency and good safety.

[0005] The technical problem to be solved by this utility model is achieved through the following technical solution:

[0006] A handle sewing device for a tote bag, comprising:

[0007] The roll module is used to wind the strip to be processed;

[0008] A length-fixing module is used to process the material strip into a handle of a predetermined length;

[0009] A sewing module for sewing the handle strap onto the bag body;

[0010] A feeding module is used to transport the handle strap from the fixed-length module to the sewing module;

[0011] The roll module, length-fixing module, and sewing module are sequentially connected along a first direction, and the feeding module is connected along a second direction and disposed beside the length-fixing module and the sewing module. The feeding module includes a gripping mechanism, a first moving mechanism, and a second moving mechanism. The first moving mechanism drives the gripping mechanism to move along the first direction. When the gripping mechanism moves to one end of the first direction, it aligns with the length-fixing module, and when it moves to the other end of the first direction, it aligns with the sewing module. The second moving mechanism drives the gripping mechanism to move along the second direction. When the gripping mechanism moves to one end of the second direction, it extends into the length-fixing module or the sewing module, and when it moves to the other end of the second direction, it extends out of the length-fixing module or the sewing module.

[0012] Furthermore, the first direction is perpendicular to the second direction.

[0013] Furthermore, the hand clamping mechanism includes a first feeding clamp and a second feeding clamp, a first rotary driver and a second rotary driver, wherein the first feeding clamp and the second feeding clamp are arranged side by side along the first direction and are both parallel to the second direction; the first rotary driver is connected to drive the first feeding clamp to rotate around its own central axis, and the second rotary driver is connected to drive the second feeding clamp to rotate around its own central axis.

[0014] Furthermore, the hand clamping mechanism also includes a position adjustment component, which is connected to drive the first feeding clamp and the second feeding clamp to adjust their positions along the first direction.

[0015] Furthermore, the position adjustment assembly includes a base, a first linear guide rail, a second linear guide rail, a first slide, a second slide, a first linear adjuster, and a second linear adjuster. The first linear guide rail and the second linear guide rail are arranged side by side on the base along the first direction and are both parallel to the first direction. The first slide is disposed on the first linear guide rail, and the first linear adjuster is disposed on the base and connected to adjust the position of the first slide on the first linear guide rail.

The first feeding clamp and the first rotary driver are disposed on the first slide, and the second feeding clamp and the second rotary driver are disposed on the second slide.

[0016] Furthermore, the fixed-length module includes:

[0017] A movable gripper and a fixed gripper are used to grip the material strip and are arranged opposite to each other along the first direction. The movable gripper is located on the side closer to the winding module, and the fixed gripper is located on the side closer to the sewing module.

[0018] A gripper moving mechanism is used to connect and drive the moving gripper to move between the coil module and the fixed gripper along the first direction;

[0019] A cutting mechanism is used to cut the material strip to form the handle strip, and is located between the moving gripper and the fixed gripper.

[0020] Furthermore, when the gripper mechanism moves to the side aligned with the fixed-length module, and the moving gripper moves to the side close to the coil module, the gripper mechanism aligns with the gap area between the cutting mechanism and the fixed gripper.

[0021] Furthermore, the cutting mechanism includes a mechanical cutter head and a cutter head lifting assembly. The cutter head lifting assembly drives the mechanical cutter head to move up and down, so that the mechanical cutter head cuts the material strip.

[0022] Furthermore, the cutting mechanism also includes an ultrasonic cutting station, which is fixedly disposed below the mechanical cutting head to cooperate with the mechanical cutting head to cut the material strip when the mechanical cutting head is lowered.

[0023] Furthermore, the mechanical cutter head and the cutter head lifting assembly are disposed on the movable gripper so as to move along the first direction with the movable gripper. When the mechanical cutter head moves to one end of the first direction, it is aligned with the ultrasonic cutter stage, and when it moves to the other end of the first direction, it is located above the fixed gripper.

[0024] This utility model has the following beneficial effects: The handle sewing device of this utility model automatically sews the handle strap onto the bag body through the cooperation between the material rolling module, the length fixing module, the feeding module and the sewing module, resulting in high production efficiency and good safety. In addition, the material rolling module, the length fixing module and the sewing module are connected and arranged sequentially along the first direction, while the feeding module is arranged along the second direction next to the length fixing module and the sewing module. The hand clamping mechanism is reciprocated and extended and retracted next to the length fixing module and the sewing module through the first moving mechanism and the second moving mechanism, so that the feeding module does not need to avoid the length fixing module and the sewing module when feeding, simplifying the feeding process.

[0032] Example 1

[0033] like Figure 1 As shown, a handle sewing device for a tote bag includes:

[0034] The roll module 1 is used to wind the strip to be processed;

[0035] The length-fixing module 2 is used to process the material strip into a handle of a predetermined length;

[0036] Sewing module 3 is used to sew the handle strap onto the bag body;

[0037] Feeding module 4 is used to transport the handle strap from the fixed length module 2 to the sewing module 3;

[0038] The roll module 1, the length-fixing module 2, and the sewing module 3 are sequentially connected along the first direction x, and the feeding module 4 is disposed beside the length-fixing module 2 and the sewing module 3 along the second direction y; Figure 2The feeding module 4 includes a gripping mechanism 41, a first moving mechanism 42, and a second moving mechanism 43. The first moving mechanism 42 drives the gripping mechanism 41 to move along the first direction x. When the gripping mechanism 41 moves to one end of the first direction x, it aligns with the fixed-length module 2. When it moves to the other end of the first direction x, it aligns with the sewing module 3. The second moving mechanism 43 drives the gripping mechanism 41 to move along the second direction y. When the gripping mechanism 41 moves to one end of the second direction y, it extends into the fixed-length module 2 or the sewing module 3. When it moves to the other end of the second direction y, it extends out of the fixed-length module 2 or the sewing module 3.

[0039] The handle sewing device of this utility model automatically sews the handle strap onto the bag body through the cooperation of the material rolling module 1, the length fixing module 2, the feeding module 4, and the sewing module 3, resulting in high production efficiency and good safety. In addition, the material rolling module 1, the length fixing module 2, and the sewing module 3 are sequentially connected along the first direction x, while the feeding module 4 is arranged along the second direction y to one side of the length fixing module 2 and the sewing module 3. The hand clamping mechanism 41 is reciprocated and extended and retracted next to the length fixing module 2 and the sewing module 3 through the first moving mechanism 42 and the second moving mechanism 43, so that the feeding module 4 does not need to avoid the length fixing module 2 and the sewing module 3 when feeding, simplifying the feeding process.

[0040] In this embodiment, the first moving mechanism 42 and the second moving mechanism 43 may, but are not limited to, employ a motor drive + lead screw transmission, a motor drive + belt transmission, or direct drive by a drive cylinder, and are provided with corresponding guide rail assemblies to limit the moving direction. Preferably, the first direction x is perpendicular to the second direction y.

[0041] Specifically, when using the handle sewing device, the operator first winds the material strip to be processed onto the material winding module 1, pulls the end of the material strip into the fixed-length module 2, and then starts the handle sewing device. After starting, the handle sewing device automatically performs the following steps:

[0042] The first moving mechanism 42 moves the hand clamping mechanism 41 to the side of the fixed length module 2 so that the hand clamping mechanism 41 is aligned with the fixed length module 2;

[0043] The fixed-length module 2 processes the material strip into a handle of a predetermined length;

[0044] The second moving mechanism 43 extends the hand clamping mechanism 41 into the fixed length module 2 so that the hand clamping mechanism 41 can clamp the handle strap located in the fixed length module 2. The second moving mechanism 43 then extends the hand clamping mechanism 41 out of the fixed length module 2 so that the hand clamping mechanism 41 can remove the handle strap from the fixed length module 2.

[0045] The first moving mechanism 42 moves the hand clamping mechanism 41 to the side of the sewing module 3 so that the hand clamping mechanism 41 is aligned with the sewing module 3;

[0046] The second moving mechanism 43 extends the hand clamping mechanism 41 into the sewing module 3 so that the hand clamping mechanism 41 can feed the handle strap into the sewing module 3, and then the second moving mechanism 43 extends the hand clamping mechanism 41 out of the sewing module 3.

[0047] The sewing module 3 sews the handle strap onto the bag body.

[0048] The tote bag can be manually fed into the sewing module 3 by an operator, or it can be fed into the sewing module 3 by a dedicated feeding module.

[0049] The hand clamping mechanism 41 includes a first feeding clamp 411 and a second feeding clamp 412, a first rotary driver 413 and a second rotary driver 414. The first feeding clamp 411 and the second feeding clamp 412 are arranged side by side along the first direction x and are both parallel to the second direction y. The first rotary driver 413 drives the first feeding clamp 411 to rotate around its own central axis, and the second rotary driver 414 drives the second feeding clamp 412 to rotate around its own central axis.

[0050] When the hand clamping mechanism 41 clamps the handle belt, the first feeding clamp 411 and the second feeding clamp 412 respectively clamp the two ends of the handle belt. Then, the first rotary driver 413 and the second rotary driver 414 respectively drive the first feeding clamp 411 and the second feeding clamp 412 to rotate, so as to fold the two ends of the handle belt relative to its middle part.

[0051] The rotation angle of the first feed clamp 411 and the second feed clamp 412 can be set according to the sewing requirements of the handle strap, and can rotate 90° or 180°. Preferably, the rotation angles of the first feed clamp 411 and the second feed clamp 412 are opposite, that is, one of the first feed clamp 411 and the second feed clamp 412 rotates clockwise, while the other rotates counterclockwise.

[0052] In this embodiment, the first rotary driver 413 and the second rotary driver 414 may be, but are not limited to, a rotary motor or a rotary cylinder.

[0053] In some examples, the hand clamping mechanism 41 further includes a position adjustment component, which is connected to drive the first feeding clamp 411 and the second feeding clamp 412 to adjust their positions along the first direction x, so that the first feeding clamp 411 and the second feeding clamp 412 can be adapted to handles of different lengths.

[0054] The position adjustment assembly includes a base 415, a first linear guide rail 416, a second linear guide rail 417, a first slide 418, a second slide 419, a first linear adjuster 4110, and a second linear adjuster 4111. The first linear guide rail 416 and the second linear guide rail 417 are arranged side by side on the base 415 along the first direction x and are both parallel to the first direction x. The first slide 418 is disposed on the first linear guide rail 416, and the first linear adjuster 4110 is disposed on the base 415 and connected to adjust the position of the first slide 418 on the first linear guide rail 416. The second slide 419 is disposed on the second linear guide rail 417, and the second linear adjuster 4111 is disposed on the base 415 and connected to adjust the position of the second slide 419 on the second linear guide rail 417. The first feed clamp 411 and the first rotary driver 413 are disposed on the first slide 418, and the second feed clamp 412 and the second rotary driver 414 are disposed on the second slide 419.

[0055] The first linear adjuster 4110 and the second linear adjuster 4111 adjust the relative position between the first feeding clamp 411 and the second feeding clamp 412 and the fixed length module 2 or the sewing module 3, and the spacing between the first feeding clamp 411 and the second feeding clamp 412, by pushing the first slide block 418 and the second slide block 419 so that the first slide block 418 and the second slide block 419 slide on the first linear guide rail 416 and the second linear guide rail 417, respectively.

[0056] In this embodiment, the first linear adjuster 4110 and the second linear adjuster 4111 may be, but are not limited to, floating adjustment joints. The floating adjustment joint has a screw and nut structure, and the extension length of the screw can be adjusted by rotating the nut, thereby causing the screw to push the first slide 418 and the second slide 419 to slide on the first linear guide 416 and the second linear guide 417 respectively.

[0057] Implementation of Column 2

[0058] As an optimization of Embodiment 1, in this embodiment, such as Figure 3 As shown, the fixed-length module 2 includes:

[0059] A movable gripper 21 and a fixed gripper 22 are used to grip the material strip and are arranged opposite to each other along the first direction x. The movable gripper 21 is located on the side closer to the winding module 1, and the fixed gripper 22 is located on the side closer to the sewing module 3.

[0060] The gripper moving mechanism 23 is used to connect and drive the moving gripper 21 to move along the first direction x between the coil module 1 and the fixed gripper 22;

[0061] The cutting mechanism 24 is used to cut the material strip to form the handle strip, and is located between the moving gripper 21 and the fixed gripper 22.

[0062] The handle sewing device of this utility model, through the cooperation between the moving gripper 21, the fixed gripper 22, the gripper moving mechanism 23 and the cutting mechanism 24, pulls the material strip from the roll module 1 to a predetermined length and cuts it to form the handle strip.

[0063] Specifically, when the length-fixing module 2 processes the material strip into a handle of a predetermined length, the following steps are included:

[0064] The gripper moving mechanism 23 drives the moving gripper 21 to move to the side close to the coil module 1, so that the operator can put the end of the material strip into the moving gripper 21;

[0065] The movable gripper 21 grasps the head of the strip, and the strip cutting mechanism 24 cuts off the portion of the strip that exceeds the required length.

[0066] The gripper moving mechanism 23 drives the moving gripper 21 to move to the side close to the fixed gripper 22, so that the moving gripper 21 pulls the strip out of the winding module 1 by a predetermined length and feeds the strip head into the fixed gripper 22;

[0067] The fixed gripper 22 grasps the belt head, and the movable gripper 21 releases the belt head;

[0068] The gripper moving mechanism 23 drives the moving gripper 21 to move to the side close to the coil module 1, and the moving gripper 21 grabs the pulled-out strip;

[0069] The cutting mechanism 24 cuts the pulled-out strip so that the strip on the fixed gripper 22 forms the handle, while the strip on the movable gripper 21 forms a new head.

[0070] The moving distance of the movable gripper 21 is set according to the predetermined length of the handle strap.

[0071] In this embodiment, the gripper moving mechanism 23 may be, but is not limited to, using a motor drive + lead screw transmission, or a motor drive + belt transmission, or a drive cylinder for direct drive.

[0072] Preferably, when the gripper mechanism 41 moves to the side aligned with the fixed length module 2, and the moving gripper 21 moves to the side close to the winding module 1, the gripper mechanism 41 is aligned with the gap between the cutting mechanism 24 and the fixed gripper 22, so that before the cutting mechanism 24 cuts the pulled-out strip, the second moving mechanism 43 can extend the gripper mechanism 41 into the gap between the cutting mechanism 24 and the fixed gripper 22, so that the first feeding clamp 411 and the second feeding clamp 412 can respectively grab the two ends of the uncut handle strip.

[0073] The cutting mechanism 24 includes a mechanical cutter head 241 and a cutter head lifting assembly 242. The cutter head lifting assembly 242 drives the mechanical cutter head 241 to move up and down so that the mechanical cutter head 241 cuts the material strip.

[0074] Preferably, the cutting mechanism 24 further includes an ultrasonic cutting station 243, which is fixedly disposed below the mechanical cutting head 241 so as to abut against the mechanical cutting head 241 when the mechanical cutting head 241 is lowered, thereby cutting the material strip.

[0075] Preferably, the mechanical cutter head 241 and the cutter head lifting assembly 242 are disposed on the movable gripper 21 so as to move along the first direction x with the movable gripper 21. When the mechanical cutter head 241 moves to one end of the first direction x, it is aligned with the ultrasonic cutter stage 243, and when it moves to the other end of the first direction x, it is located above the fixed gripper 22.

[0076] The handle sewing device of this utility model sets the mechanical cutter head 241 and the cutter head lifting assembly 242 on the movable gripper 21. In this way, when the movable gripper 21 pulls out the material strip, the mechanical cutter head 241 does not need to raise to avoid the movable gripper 21 and the gripper moving mechanism 23. It only needs to raise to avoid the fixed gripper 22. Since the fixed gripper 22 has a fixed position and no corresponding moving mechanism, the avoidance range is small. Therefore, the lifting stroke of the cutter head lifting assembly 242 can be shortened, thereby improving the lifting stability.

[0077] In this embodiment, the cutter head lifting assembly 242 may be driven by a motor and a lead screw, or driven by a motor and a belt, or driven directly by a drive cylinder.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present utility model, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the present utility model.
