Description

Technical Field

[0001] This utility model belongs to the field of bag opening machine technology, and relates to a bag cloth sorting mechanism for a bag opening machine. Background Technology

[0002] A pocket opening machine is a special sewing machine for sewing the opening of pockets in clothing. When the pocket opening machine is working, it first cuts a "I" shaped pocket seam on the surface of the fabric, and then folds and clamps the free fabric on both sides of the pocket seam through the folding mechanism for subsequent sewing to form a pocket. In the process of sewing a real pocket, the front and back pocket fabrics need to be fed twice and sewn twice.

[0003] For example, patent application publication number CN117966377A discloses a bag opening machine and a bag opening sewing process. The bag opening machine is equipped with a worktable. After the bag opening fabric piece and the accessory are sewn together for the first time, the first drive mechanism drives the bag opening forming device C and the material support plate to move together to the bag opening fabric piece feeding station and release the first material support plate. The bag opening forming device C then continues to move to the accessory feeding station and descends above another material support plate so that the sewn bag opening fabric piece is overlapped with another accessory (bag fabric).

[0004] The above-mentioned bag opening function enables the automated sewing of genuine pockets, but there are still shortcomings: after the first support plate is released, the bag fabric that has been sewn for the first time will hang down, and may be deflected backward due to the movement of the first support plate. When it is subsequently moved to the top of another support plate and lowered, the deflected part can easily form wrinkles and interfere with the sewing area of ​​the second bag fabric, resulting in mis-sewing. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing a bag fabric sorting mechanism for a bag opening machine. The technical problem this utility model aims to solve is that existing bag opening machines are prone to wrinkles and mis-sewing when sewing genuine pockets.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A bag-opening machine includes a bag-opening machine with a bag-opening cloth sorting mechanism. The bag-opening machine includes a worktable, and the bag-opening cloth sorting mechanism includes a pressure frame seat connected to the worktable and capable of horizontal and vertical movement. The surface of the worktable has a plurality of suction holes for adsorbing the bag-opening cloth. The bag-opening cloth sorting mechanism further includes a crossbar connected to the worktable around the suction holes and capable of horizontal movement. The crossbar is horizontally arranged in the left-right direction and can be moved to directly above the suction holes. When the pressure frame seat is above the crossbar, the crossbar can be moved forward along the bottom surface of the pressure frame seat to the front side of the pressure frame seat.

[0008] The upper part of the pressing frame seat is used for placing the fabric of the to-be-opened pocket, the air suction hole is used for sucking and avoiding displacement of the upper pocket cloth, the first existing bottom template is placed in advance at the air suction hole, and the front pocket cloth is positioned and placed on the first bottom template, the fabric on the pressing frame seat is moved left and right to the air suction hole after cutting is completed, and is moved downward to be locked with the first bottom template below, then the pressing frame seat is moved synchronously to the sewing position to perform first sewing, after the sewing is completed, the pressing frame seat drives the first bottom template to move upward and translate to above the air suction hole, at this time, the second bottom template is placed in advance at the air suction hole, and the back pocket cloth is positioned and placed on the second bottom template, then the first bottom template below the pressing frame seat is separated, and the pressing frame seat is controlled to move downward to be locked with the second bottom template and move to the sewing position to perform second sewing to complete the true pocket making; the horizontal rod is arranged on the workbench and can move forward and backward, and the horizontal rod can move forward from the air suction hole below the pressing frame seat to the front side of the pressing frame seat, so that when the first bottom template is separated, the horizontal rod can be arranged to move forward synchronously, so that the front pocket cloth which loses the constraint of the first bottom template at this time can fall to the front of the horizontal rod below, and the front pocket cloth can be rolled flat once by rolling the front pocket cloth forward along with the horizontal rod, and the back pocket cloth can be kept relatively flat after falling again without being disturbed by the first bottom template, so that the missewing phenomenon is avoided.

[0009] In the pocket cloth arrangement mechanism of the pocket opening machine, the horizontal rod can also move up and down. In this way, before placing the back pocket cloth, the horizontal rod can also move forward and backward to above the second bottom template and move downward to form a positioning backstop of the back pocket cloth, so as to facilitate accurate placement of the back pocket cloth.

[0010] In the pocket cloth arrangement mechanism of the pocket opening machine, one side edge of the workbench in the left-right direction is provided with a moving arm extending upward beyond the upper side of the workbench, a guide rail one in the form of a strip plate is fixed below the workbench and arranged horizontally in the front-rear direction, an installation seat which can slide forward and backward is connected to the guide rail one, a guide rail two which is arranged vertically is fixed to the installation seat, the moving arm is connected to the guide rail two, and the horizontal rod is fixed to the upper end of the moving arm. In this way, the moving arm is arranged at one side edge of the workbench, which is conducive to reducing the interference influence of the mechanism on the movable mechanism above the workbench.

[0011] In the pocket cloth arrangement mechanism of the pocket opening machine, the upper end of the moving arm is fixed with a strip-shaped cantilever arranged forward, and the horizontal rod is connected to the front end of the cantilever. In this way, the cantilever is conducive to enabling the horizontal rod to move forward to a farther position, so as to facilitate the horizontal rod to be separated from the area of the workbench when the horizontal rod does not function, and further avoid the interference influence on the movable mechanism above the workbench.

[0012] In the bag cloth arrangement mechanism of the bag opening machine, the upper side of the workbench has a strip-shaped through hole arranged in the front-rear direction, and the moving arm is located in the strip-shaped through hole. Thus, the strip-shaped hole can accommodate the moving arm, facilitate the built-in protection of the moving arm related structure in the space below the workbench, and protect the service life of the mechanism.

[0013] In the bag cloth arrangement mechanism of the bag opening machine, the guide rail is connected with a servo motor for driving the mounting seat to move forward and backward. Thus, the position and action of the cross rod can be accurately controlled by the servo motor, the control accuracy is guaranteed, and the adaptive position and action of the cross rod for different types of bags can be controlled by the program.

[0014] In the bag cloth arrangement mechanism of the bag opening machine, the upper side of the cross rod is fixedly provided with a soft brush arranged in the axial direction of the cross rod. Thus, rigid friction between the upper side of the cross rod and the first bottom plate can be avoided, and sufficient contact and smoothing effect on the front bag cloth can be ensured.

[0015] In the bag cloth arrangement mechanism of the bag opening machine, the cross section of the cross rod is in the shape of a U-shaped opening downward. Thus, the lightweight design of the cross rod can be realized by the hollow structure, and the cross rod will not block the air suction hole when it moves downward, thereby avoiding increasing the air suction resistance.

[0016] Compared with the prior art, the bag cloth arrangement mechanism of the bag opening machine has the following advantages:

[0017] The bag cloth arrangement mechanism of the bag opening machine can smooth the front bag cloth before it overlaps with the rear bag cloth during the sewing of the real pocket, avoid the missewing caused by the folding and wrinkling of the front bag cloth during the extraction of the bottom template, and guarantee the sewing quality of the real pocket.

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] Example 1:

[0028] like Figures 1-5 As shown, in the bag fabric sorting mechanism of this bag opening machine, the bag opening machine includes a worktable 1. A horizontally arranged truss 102 is fixed on the worktable 1. The feeding mechanism includes a pressure frame seat 2 connected to the truss 102 and capable of horizontal and vertical movement. The surface of the worktable 1 has a plurality of suction holes 11 for adsorbing the bag fabric. The suction holes 11 are in the shape of a mesh plate. A horizontal bar 3 capable of horizontal movement is connected to the worktable 1 around the suction holes 11. The cross section of the horizontal bar 3 is U-shaped with the opening facing downward. The horizontal bar 3 is horizontally arranged in the left and right direction and can move to the top of the suction holes 11. When the pressure frame seat 2 is above the horizontal bar 3, the horizontal bar 3 can move forward along the bottom surface of the pressure frame seat 2 to the front side of the pressure frame seat 2. The horizontal bar 3 can also move up and down. A movable arm 4, extending from the upper side of the workbench 1, is located on the left side of the workbench 1. A horizontally arranged, strip-shaped guide rail 5 is fixed below the workbench 1. A sliding mounting base 6 is connected to the guide rail 5, and a vertically arranged guide rail 7 is fixed to the mounting base 6. The movable arm 4 is connected to the guide rail 7, and a crossbar 3 is fixed to the upper end of the movable arm 4. Specifically, a forward-facing cantilever 8 is fixed to the upper end of the movable arm 4, and the crossbar 3 is connected to the front end of the cantilever 8. The upper side of the workbench 1 has a strip-shaped through hole 12 arranged in the front-back direction. The movable arm 4 is located within the strip-shaped through hole 12. Servo motors 9 are connected to the guide rail 5 to drive the mounting base 6 to move forward and backward. The up-and-down movement of the movable arm 4 can be controlled by a vertical electric actuator (not shown). The connection method of the servo motor 9 and the electric actuator is existing technology.

[0029] During the sewing of the real pocket, the existing first bottom template (not shown) is first moved to the air intake 11. The horizontal bar 3 moves backward to a preset position above the first bottom template and then moves down to contact the first bottom template, allowing the user to place the front pocket fabric and other accessories to be sewn on the horizontal bar 3 as a reference. After placement, the horizontal bar 3 rises and moves forward to reset. Then, the fabric that has been cut and hemmed on the pressure frame 2 moves with the pressure frame 2 to the top of the first bottom template and moves down to lock with the first bottom template. Then, the first sewing is performed together. During the sewing process, the second bottom template moves to the air intake hole 11, and the horizontal bar 3 moves backward to the preset position above the second bottom template and moves down to provide positioning for the placement of the back pocket fabric. Then, the pressure frame seat 2 moves the first bottom template and the sewn fabric to the horizontal bar 3 and the second bottom template. The operation pulls the first bottom template backward, and then the horizontal bar 3 moves up and forward to smooth the front pocket fabric once. Finally, after the horizontal bar 3 moves out of the range of the pressure frame seat 2, the pressure frame seat 2 moves down to lock with the second bottom template and moves to the sewing position to complete the second sewing.

[0030] Example 2:

[0031] like Figure 6 As shown, this embodiment is basically the same as embodiment one, except that a soft brush 101 arranged along the axial direction of the crossbar 3 is fixed on the upper side of the crossbar 3.

[0032] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
