Description

Technical Field

[0001] This utility model relates to the field of hanging bag sewing technology, and in particular to an automatic hanging bag sewing machine. Background Technology

[0002] Lifting bags consist of bag panels and straps sewn onto the bag panels. Because lifting bags are relatively large, the straps need to be reserved at the four corners of the bag panels. Currently, most companies in the industry use manual labor to hold the bag panels and sew the straps along the marked lines on the bag panels using a sewing machine. This method has some drawbacks: it involves a lot of manual labor, has a low degree of automation, is inefficient, and the consistency of processing quality is not ideal.

[0003] CN216765268U describes an automatic sewing device for reinforcing blocks and straps of FIBCs (Flexible Intermediate Bulk Containers), comprising a frame, a truss-type sewing machine, and a tensioning sleeve. The frame is equipped with a first guide rail fixing plate. The truss-type sewing machine includes an X-axis motion system, a Y-axis motion system, and a Z-axis motion system. The X-axis motion system includes a first guide rail, a first transmission bar, an X-axis motor, and a first roller bearing. The Y-axis motion system includes a second guide rail, a second transmission bar, a Y-axis motor, a sewing head, a sewing head drive cylinder, a second roller bearing, a sewing needle, and a sewing needle drive mechanism. The Z-axis motion system includes a fourth guide rail, a third transmission bar, a Z-axis motor, a balance cylinder, and a third roller bearing. The tensioning sleeve includes a tensioning mechanism, a rotating mechanism, a tensioning sleeve assembly, and a tensioning sleeve base. This automatic sewing device for reinforcing blocks and straps of FIBCs has a high degree of automation, replacing traditional manual sewing of the reinforcing blocks and straps, thus improving sewing efficiency and product quality.

[0004] However, its tensioning sleeve is not suitable for the feeding and positioning of the above-mentioned lifting bags (including bag panels and straps sewn on the bag panels). In other words, the automatic sewing equipment for the reinforcing block and lifting straps of the container bag disclosed in CN216765268U cannot meet the automated strap sewing processing operation of the bag panel type lifting bag.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

The clamps clamp and tighten the bag piece around its perimeter. The sewing machine head sews and fixes the tape provided by the tape feeding mechanism onto the bag piece to form a hanging bag. After the clamps are released, the bag falls onto the unloading transfer carrier. The unloading transfer carrier is driven by the unloading translation drive mechanism to move the hanging bag out from under the bag piece clamping and positioning assembly.

[0017] As a preferred embodiment, the automatic feeding robot is a needle-type suction robot.

[0018] As a preferred embodiment, the automatic translation mechanism includes a first motor, a gear, and racks arranged on opposite sides. The racks extend to the left and right. The first motor drives the gear to rotate, and the gear meshes with the corresponding rack and moves left and right along the rack.

[0039] Please refer to Figures 1 to 10 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0040] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] An automatic sewing machine for hanging bags includes, from right to left, a bag stacking rack 1, a feeding device 2, a transfer carrier 3, a sewing device 4, a strap feeding mechanism 5, a bag clamping and positioning assembly 6, and a discharge transfer carrier 7, wherein:

[0042] The bag stacking rack 1 is used to place bags stacked one on top of the other;

[0043] The feeding device 2 includes an automatic feeding robot 201, an automatic lifting mechanism 202 that drives the automatic feeding robot 201 to move up and down, and an automatic translation mechanism 203 that drives the automatic lifting mechanism 202 and the automatic feeding robot 201 to move left and right together. The automatic feeding robot 201 is a needle-type suction robot, which is usually equipped with multiple (e.g., four, arranged in a four-corner arrangement) needle-type suction heads that can pierce downward into the four corners of the bag. When the automatic feeding robot 201 is driven to rise by the automatic lifting mechanism 202, it can lift a bag upward and then move it to the left to be sent to the intermediate transfer carrier 3. In this embodiment, the automatic lifting mechanism 202 is driven by a motor A to drive a lead screw B. The lead screw extends vertically. When the motor is working, the lead screw rotates, driving the automatic feeding robot 201 and the automatic translation mechanism 203 to move up and down along the lead screw. The automatic translation mechanism 203 includes a first motor 2031, a gear 2032, and racks 2033 arranged on opposite sides. The racks extend left and right. The first motor drives the gear to rotate, and the gear meshes with the corresponding rack and moves left and right along the rack.

[0044] The intermediate transfer carrier 3 is connected to an intermediate transfer translation drive mechanism. The intermediate transfer carrier 3 is located in the area between racks 2033 arranged on opposite sides. Typically, the bag stacking material rack 1 is also located at the right end of the area between the racks arranged on opposite sides. The intermediate transfer translation drive mechanism includes a second motor 301 and a synchronous belt 302. The synchronous belt extends left and right. The second motor drives the synchronous belt to move, and the intermediate transfer carrier 3 translates left and right with the synchronous belt. Guide rails 303 extending left and right are respectively arranged on the front and rear sides of the synchronous belt, and the intermediate transfer carrier 3 is slidably arranged along the guide rails. The intermediate transfer carrier 3 is provided with multiple automatically opening and closing first bag clamps 304, which are used to press the periphery of the bag. When the automatic feeding robot 201 delivers the bag to the intermediate transfer carrier 3, the first bag clamps 304 clamp and position the bag, and the automatic feeding robot 201 can detach from the bag. Here, the first bag clip 304 is a structure that can be flipped up and down. In the open state, the first bag clip 304 is vertically upward, while in the clamped state, the first bag clip 304 flips down towards the central transfer carrier 3 to a horizontal state to press down the bag clip. This first bag clip 304 is driven by a cylinder to flip up and down.

[0045] The sewing device 4 includes a sewing machine head 401, a head translation drive mechanism 402 for driving the sewing machine head 401 to translate, and a head rotation drive mechanism 403 for driving the sewing machine head 401 to rotate; for example, the head translation drive mechanism 402 drives the head rotation drive mechanism 403 and the sewing machine head 401 to translate left and right together. The sewing machine head 401 has forward and backward translation functions and rotation functions.

[0046] The tape feeding mechanism 5 is used to feed tape toward the sewing device 4; it is a mature technology, in which the tape is loaded in the form of a reel and then automatically pulled out, which can realize functions such as fixed length pulling out and automatic cutting.

[0047] The bag clamping and positioning assembly 6 includes a base plate 601 and a plurality of automatically opening and closing clips 602 mounted on the base plate 601. Each clip is equipped with a clip translation drive mechanism 603. A clearance hole 604 is provided on the base plate 601, and the clips are mounted around the clearance hole. The bag clamping and positioning assembly 6 is connected to the bag sewing translation drive mechanism. The bag clamping and positioning assembly 6 further includes the base plate 601, on which the clearance hole is provided, and the clip translation drive mechanism is mounted on the base plate 601, such that the clips are mounted around the clearance hole.

[0048] The feeding transfer seat 7 is connected to a feeding translation drive mechanism. Multiple automatically opening and closing second bag clips 701 are provided on the feeding transfer seat 7 to press down the periphery of the bag pieces. Referring to the first bag clip 304, the second bag clips 701 here are also a structure that can flip up and down. In the open state, the second bag clips 701 are vertically upward, while in the clamped state, the second bag clips 701 flip downward towards the central transfer seat 3 to a horizontal state to press down the bag pieces. This type of second bag clip 701 is driven to flip up and down by a cylinder. The feeding transfer seat 7 is connected to a feeding lifting mechanism 702, which drives the feeding transfer seat 7 to move up and down to receive the suspended bags and move downward away from the bag clamping and positioning assembly 6. The feeding translation drive mechanism includes a third motor 703 and a lead screw 704. The lead screw extends left and right, and the third motor drives the lead screw to rotate. The feeding lifting mechanism 702 is mounted on a connecting seat 705. An internal threaded block connected to the lower end of the connecting seat 705 is adapted to the lead screw 704 and can move left and right along the lead screw under the drive of the lead screw. There are two sets of lead screws, arranged opposite each other front and back. Correspondingly, there are also two sets of connecting seats and internal threaded blocks. The feeding transfer seat 7 is designed as two separate parts, front and back, with a second bag clamp 701 set at the top left and right ends of each part. Each part is equipped with a feeding transfer seat 7. In other embodiments, the feeding transfer seat 7 can also be designed as an integral piece.

[0049] The automatic bag sewing machine is divided into a feeding section D1, a sewing section D2, and a discharging section D3 from right to left. The front-to-back width of the feeding section is smaller than that of the sewing section, and the front-to-back width of the discharging section is smaller than that of the sewing section. The sewing section is provided with side bases D21 on opposite sides. The bag clamping and positioning assembly 6 is automatically moved left and right along the side bases. For example, the bag sewing translation drive mechanism includes a motor 605, a synchronous belt 606, and a gear 607 mounted on the base plate 601 of the bag clamping and positioning assembly 6. It also includes a rack 608 extending left and right on the side base D21. The output end of the motor drives the gear through the synchronous belt. The gear meshes with the rack and moves left and right along the rack. A gantry-type suspension beam D22 extending forward and backward is connected between the two side base frames D21. The machine head translation drive mechanism 402 is installed on the gantry-type suspension beam D22, so that the sewing machine head 401 can translate forward and backward along the gantry-type suspension beam. The feeding transfer seat 7 and the feeding translation drive mechanism can extend into the area between the front and rear opposite side base frames D21.

[0050] During operation, a stack of bag pieces is placed on the bag piece stacking rack 1. The automatic feeding robot 201, driven by the automatic lifting mechanism 202, picks up the bag pieces downwards and, driven by the automatic translation mechanism 203, moves the bag pieces to the left onto the intermediate transfer carrier 3. The intermediate transfer carrier 3, driven by the intermediate translation drive mechanism, sends the bag pieces to the left onto the bag piece clamping and positioning assembly 6, where clamps hold and tighten the bag pieces around their perimeter. Usually, there are also clamps tightening the bag pieces at the sewing inlet and outlet points. The intermediate transfer carrier 3 then moves to the right to the waiting area, ready to receive the next bag piece delivered by the automatic feeding robot 201. The sewing machine head 401 then feeds the tape into the machine via the tape feeding mechanism 5. The supplied straps are pressed down and sewn onto the bag piece to form a hanging bag. During sewing, the bag piece clamping and positioning component 6 moves left and right, and the sewing machine head 401 moves forward and backward and rotates to sew the straps into the desired shape on the bag piece. After sewing, the material transfer seat 7 is waiting below the bag piece clamping and positioning component 6. When the clamp of the bag piece clamping and positioning component 6 is released, the bag falls onto the material transfer seat 7. Driven by the material transfer drive mechanism, the material transfer seat 7 moves the hanging bag from below the bag piece clamping and positioning component 6 to the left, and then moves it back to the left to return to below the bag piece clamping and positioning component 6.

[0051] like Figure 11The diagram shows the general structure of a hanging bag, an example of a product that can be automatically processed by the automatic sewing machine of this utility model. Eight sewing entry / exit points are provided on the bag piece a1, numbered F1 to F8. The beginning and end of the strap a2 on the bag piece a1 generally have a small overlapping section reserved to strengthen the connection between the strap a2 and the bag piece a1. The strap a2 extends from the four corners of the bag piece a1 to form arc-shaped portions a3, the length of which can be reserved as needed. During use, the arc-shaped portions a3 generally deform and are no longer arc-shaped. In fact, the automatic sewing machine for hanging bags of this utility model is not limited to... Figure 11 For products with the structure shown, the length of the strap and the number of extensions of the strap on the bag can be flexibly changed as needed.

[0052] The key design feature of this utility model lies in its arrangement of a bag stacking material rack 1, a feeding device 2, a transfer carrier 3, a sewing device 4, a tape feeding mechanism 5, a bag clamping and positioning assembly 6, and a feeding transfer carrier 7. An automatic feeding robot 201, driven by an automatic lifting mechanism 202, picks up bag pieces downwards and, driven by an automatic translation mechanism 203, moves the bag pieces onto the transfer carrier 3. The transfer carrier 3, driven by a transfer and translation drive mechanism, delivers the bag pieces to the bag clamping and positioning assembly 6, where clamps hold and tighten the bag pieces around their perimeter. The sewing machine head 401 then feeds the bag pieces onto the transfer carrier 6. The tape conveyed by the sub-feeding mechanism 5 is sewn and fixed onto the bag sheet to form a hanging bag. After the clamp is released, it falls onto the unloading transfer seat 7. Driven by the unloading translation drive mechanism, the unloading transfer seat 7 moves the hanging bag out from under the bag sheet clamping and positioning component 6. Thus, automatic feeding, automatic sewing, and automatic unloading of bag sheets and tape are realized without manual intervention. The degree of automation is high, which effectively improves the processing efficiency and quality of hanging bags. It effectively solves the problems of excessive manual intervention, low degree of automation, limited efficiency, and unsatisfactory processing quality consistency in the existing technology of hanging bag sewing processing.

[0053] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
