Description

Technical Field

[0001] This invention relates to the field of automatic drawstring threading technology for tote bags, specifically, to an automatic drawstring threading device for tote bags. Background Technology

[0002] A tote bag is a simple bag made from materials such as paper, PVC holographic film, non-woven fabric, and industrial cardboard. It is commonly used by manufacturers to hold products; it is also used to hold gifts; many fashion-conscious individuals use tote bags as accessories to match their outfits. Tote bags are also known as handle bags or handbags. Due to the huge demand for tote bags, their production using tote bag manufacturing equipment has become mainstream and widely used.

[0003] In the production process of tote bags, attaching the handles is an essential step. Currently, manual threading of the handles is time-consuming, poses safety hazards, and results in inconsistent quality. Therefore, there is an urgent need for an automatic handle threading device to solve these problems. Summary of the Invention

The rope cutter is mounted on the clamping arm. The push-clamping mechanism includes a roller and a push plate. The push plate is slidably mounted on the frame. The roller is rotatably mounted on the push plate and abuts against the outside of the clamping arm. After the push plate slides, the two clamping arms clamp or release. Both clamping arms have notches. After the two clamping arms are clamped, the two notches form a rope clamping space. The rope clamping space is used to position the rope. The limiting rod is mounted on the clamping arm and is used to position the rope cutter. One end of the first spring is connected to the movable end of the clamping arm, and the other end is connected to the frame, which provides the force for the clamping arm to swing outward.

[0030] The working principle and beneficial effects of this invention are as follows: the special structure of the machine head enables multiple functions such as punching holes, attaching eyelets, and threading ropes onto the tote bag. The machine head has holes for punching holes and threading ropes, and the punching, eyeletizing, and rope threading actions on the tote bag are all performed at the holes for punching holes and threading ropes. Specifically, the eyelet holder can move up and down on the machine head. When punching holes in a tote bag, the eyelet holder rises to the eyelet and drawstring hole position to cooperate with the eyelet-punching mechanism. The eyelet-punching mechanism punches the tote bag, and the eyelet holder supports the punching action, thus creating a through hole at a suitable position on the tote bag for installing the eyelet. When attaching the eyelet, the eyelet holder is also positioned at the eyelet and drawstring hole position to cooperate with the eyelet-punching mechanism. The eyelet-punching mechanism carries the eyelet through the pre-drilled through hole and abuts against the eyelet holder. The eyelet abuts against the eyelet holder and deforms under the pressure, thus fixing it at the through hole. The eyelet facilitates the insertion of the drawstring. When threading the drawstring, the eyelet holder descends, making way for the drawstring hole. The threading mechanism carries the drawstring through the eyelet and into the drawstring hole to complete the threading action. The machine head in this embodiment has a special structure that enables multiple functions, allowing for the processing of multiple processes on the same machine head. This allows for a series of processing steps on the tote bag without changing its position, achieving full automation of punching holes and threading drawstrings on the tote bag. This effectively solves the problems of low efficiency and inconsistent quality caused by manual drawstring threading in related technologies. Attached Figure Description

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0047] like Figures 1 to 13As shown, an automatic rope threading device for tote bags includes a frame 1, a punching mechanism 2 and a rope threading mechanism 3 provided on the frame 1. The frame 1 is provided with a machine head 4, the open end of the tote bag is sleeved on the machine head 4, the machine head 4 is slidably provided with a corn eye receiving part 5, the machine head 4 has a punching and rope threading hole, and the corn eye receiving part 5 can block or open the punching and rope threading hole after sliding.

[0048] The punching mechanism 2 is used to make the eyelet pass through the handbag and be stamped onto the eyelet receiving part 5;

[0049] The rope threading mechanism 3 is used to thread the rope end into the eyelet.

[0050] In this embodiment, the special structure of the machine head 4 enables multiple functions such as punching holes, attaching eyelets, and threading ropes onto the tote bag. The machine head 4 has holes for punching holes and threading ropes, and the punching, eyeletizing, and rope threading actions on the tote bag are all performed at the holes for punching holes and threading ropes. Specifically, the eyelet holder 5 can be raised and lowered on the machine head 4. When punching holes in a tote bag, the eyelet holder 5 rises to the hole for punching and threading the rope. This is to cooperate with the punching mechanism 2 to punch holes. The punching mechanism 2 will punch the tote bag, and the eyelet holder 5 is used to support the punching action, thereby punching a through hole at a suitable position on the tote bag. The through hole is used to install the eyelet. When nailing the eyelet, the eyelet holder 5 is also located at the hole for punching and threading the rope. This is to cooperate with the punching mechanism 2 to nail the eyelet. The punching mechanism 2 will carry the eyelet through the pre-drilled through hole and abut against the eyelet holder 5. The eyelet abuts against the eyelet holder 5 and deforms under the pressure, thereby fixing it at the through hole. The eyelet is used to facilitate the threading of the rope end. When threading the rope, the eyelet holder 5 descends to make way for the hole for the rope end to enter. The threading mechanism 3 carries the rope end through the eyelet and into the hole for threading the rope. In this embodiment, the machine head 4 has a special structure that enables multiple functions, allowing for the processing of multiple processes on the same machine head 4. This allows the tote bag to undergo a series of processes without changing its position, achieving full automation of punching holes and threading ropes on the tote bag. This effectively solves the problems of low efficiency and inconsistent quality of manual rope threading in related technologies.

[0051] Furthermore, it also includes,

[0052] The eyelet receiving component 5 is rotatably provided with a pair of first rope clamps 6, and the first rope clamps 6 are located inside the eyelet and rope threading hole.

[0053] The machine head 4 is provided with a push pin 7 that slides inside. The number of push pins 7 is equal to that of the first rope clamp 6 and they correspond one-to-one. The end of the push pin 7 abuts against the first rope clamp 6 to provide force for the rotation of the first rope clamp 6.

[0054] In this embodiment, the tote bag rope is transported to the eyelet fixed on the tote bag via the rope threading mechanism 3. The machine head 4 is equipped with a first telescopic cylinder 53 and a second telescopic cylinder 54. The telescopic end of the first telescopic cylinder 53 is connected to the eyelet receiving component 5, allowing the eyelet receiving component 5 to slide within the machine head 4. When the tote bag rope is transported to the eyelet fixed on the tote bag, the eyelet receiving component 5 slides downward within the machine head 4, making the first rope clamp 6 flush with the just-fixed eyelet. The eyelet receiving component 5 rotates upward. The machine head 4 is equipped with a pair of first rope clamps 6. A pin 7 is slidably disposed inside the eyelet receiving part 5. The number of pins 7 and the number of first rope clamps 6 are equal and correspond one-to-one. The pins 7 are used to provide the force to make the first rope clamps 6 rotate on the eyelet receiving part 5. A number of second telescopic cylinders 54 are provided on the first telescopic cylinder 53. The telescopic end of the second telescopic cylinder 54 is connected to the pin 7. The extension of the second telescopic cylinder 54 causes the pin 7 to slide inside the machine head 4, thereby clamping the pair of first rope clamps 6.

[0055] During operation, the rope end covered with a hard outer sheath first passes through the eyelet and enters the hole for threading the rope. The first rope clamp 6 clamps the rope end. Then, the bag-loading mechanism 12 raises the bag a certain distance, allowing the rope to enter the eyelet a certain distance. At this time, the first rope clamp 6 is released. Finally, the bag-loading mechanism 12 transports the bag to the finished product area.

[0056] Furthermore, it also includes,

[0057] It also includes an adjustment mechanism 9, which includes an adjustment frame 10 and a first bag clamp 11. The adjustment frame 10 is slidably mounted on the frame 1 in a vertical direction, and the first bag clamp 11 is mounted on the adjustment frame 10. The first bag clamp 11 is used to position the open end of the handbag sleeved on the machine head 4.

[0058] In this embodiment, an adjustment frame 10 is slidably mounted on the frame 1 along the vertical direction. The adjustment frame 10 is equipped with a first bag clamp 11. When the tote bag is put onto the machine head 4, the first bag clamp 11 clamps the opening end of the tote bag to achieve the positioning of the tote bag, waiting for the punching mechanism 2 to perform the subsequent punching process. The adjustment component 8 can be raised and lowered to adjust the positioning height of the tote bag, thereby adjusting the punching height and meeting the punching requirements of various heights of tote bags.

[0059] Furthermore, it also includes,

[0060] The bag-loading mechanism 12 includes several pulleys 13, several pulleys 14, a conveyor belt 15, a conveyor belt 16, a transmission gear 17, a transmission gear 18, a conversion rod 19, a conversion gear 20, and a baffle 21. The pulleys 13 and 14 are rotatably mounted on the frame 1. The conveyor belt 15 is fitted onto several pulleys 13, and the conveyor belt 16 is fitted onto several pulleys 14. The first transmission gear 17 is driven and connected, and the second pulley 14 and the second transmission gear 18 are driven and connected; the first pulley 13 has a pivotally mounted conversion rod 19, and the conversion gear 20 is rotatably mounted on the conversion rod 19. The conversion gear 20 meshes with the first transmission gear 17. After the conversion rod 19 swings, the conversion gear 20 simultaneously meshes with both the first transmission gear 17 and the second transmission gear 18. The baffle 21 is detachably mounted on the second conveyor belt 16.

[0061] The frame 1 has a discharge port, and a first crossbeam 22 is slidably provided on the frame 1 for adjusting the size of the discharge port. An adjusting screw 23 is rotatably provided on the frame 1, and the adjusting screw 23 is threadedly connected to the first crossbeam 22.

[0062] The frame 1 is provided with a third conveyor belt 24 and a first longitudinal moving frame 25. Multiple second bag clamps 26 are slidably provided on the third conveyor belt 24 in the vertical direction. The first longitudinal moving frame 25 is slidably provided on the frame 1 in the longitudinal direction. Suction cups 27 are slidably provided on the first longitudinal moving frame 25 in the vertical direction.

[0063] In this embodiment, the feeding mechanism is fixed on the frame and includes several pulleys 13, several pulleys 14, a conveyor belt 15, a conveyor belt 16, a transmission gear 17, a transmission gear 18, a conversion rod 19, a conversion gear 20, and a baffle 21. Pulleys 13 and 14 are rotatably mounted on the frame. The conveyor belt 15 is mounted on several pulleys 13, and the conveyor belt 16 is mounted on several pulleys 14. Pulleys 13 and 17 are coaxially connected and driven, as are pulleys 14 and 18. The conversion rod 19 is oscillating on the spindle of pulleys 13, and the conversion gear 20 is rotatably mounted on the conversion rod 19. The conversion gear 20 is always meshed with the transmission gear 17. After the conversion rod 19 oscillates, the conversion gear 20 will simultaneously mesh with both the transmission gear 17 and the transmission gear 18. At this time, transmission gear 17 drives transmission gear 28 through conversion gear 20. Transmission gear 17 and transmission gear 28 rotate in the same direction. When the spare tote bags are almost used up, conversion rod 19 swings to disengage conversion gear 20 from transmission gear 28. At this time, transmission gear 28 is driven by motor 258, causing conveyor belt 26 to transport in the opposite direction to the feeding direction. Pulley 24 drives conveyor belt 26 to transport in the opposite direction to the feeding port to continue filling tote bags, and so on. One end of the third telescopic cylinder is hinged to the frame, and the other end is hinged to the swing end of conversion rod 19, thereby controlling the swing of conversion rod. Baffle 21 is set on conveyor belt 26 and baffle 21 is detachable. When tote bags are placed on conveyor belt 26 and pressed against baffle 21, baffle 21 pushes the vertically stacked tote bags forward. The frame has a discharge port, which is formed by the frame and the first crossbeam 22. The first crossbeam 22 is slidably mounted on the frame. The adjusting screw 23 is rotatably mounted on the frame and threadedly connected to the first crossbeam 22, allowing the first crossbeam 22 to move up and down, thus adjusting the size of the discharge port to accommodate different sizes of tote bags. When a tote bag is transported to the discharge port by the conveyor belt, a suction cup 55 grips the bag and moves it to the next processing device, which is convenient and quick. The suction cup 55 is mounted on a frame that can slide along the direction of bag transport. A handwheel 56 is located at the end of the adjusting screw 23. By turning the handwheel 56, the adjusting screw 23 is rotated, and the first crossbeam 22 is threadedly connected to the adjusting screw 23. This changes the height of the first crossbeam 22, thus adjusting the size of the discharge port to accommodate different sizes of tote bags. When the shopping bags are conveyed to the discharge port by the baffle 21 on conveyor belt 2, they are prone to falling off. Therefore, a limiting soft tooth 57 is provided on the first crossbeam 22 at the discharge port. The limiting soft tooth 57 is made of a flexible material (such as rubber). The shopping bags are clamped by the limiting soft tooth 57 at the discharge port, waiting for the suction cup 55 to grab them. After the suction cup 55 grabs a shopping bag, the limiting soft tooth 57 springs back to the initial position and quickly clamps the next shopping bag, ensuring that the shopping bags do not fall off. This cycle repeats continuously.

[0064] The third conveyor belt 24 is equipped with a first bag clamp 11 and a second bag clamp 26 that slide vertically. The distance between the first bag clamp 11 and the second bag clamp 26 is fixed, allowing for vertical displacement and a larger gripping range. The first bag clamp 11 and the second bag clamp 26 have two stations. At the first station, the first bag clamp 11 grips a tote bag at the suction cup 55, and the second bag clamp 26 grips the finished tote bag after punching holes and threading ropes at the machine head 4. At the second station, the first bag clamp 26 transfers the gripped tote bag to the suction cup frame 27, and the second bag clamp 26 places the finished tote bag after punching holes and threading ropes into the finished product area. A first longitudinal moving frame 25 is slidably mounted on the frame 1. Multiple suction cups 55 are slidably mounted on the first longitudinal moving frame 25 in the vertical direction. When the first bag clamp 11 clamps the tote bag and transports it to the machine head 4, the paired suction cup frames 27 suck up the tote bag. The two suction cup frames 27 move away from each other by sliding on the first longitudinal moving frame 25 in the vertical direction, causing the two sides of the tote bag to move away from each other, thus opening the tote bag and putting it on the outside of the machine head 4, waiting for the rope threading mechanism 3 to operate.

[0065] Furthermore, it also includes,

[0066] The system includes a rope cutting mechanism 28 and an edge-wrapping mechanism 29. The edge-wrapping mechanism 29 is used to wrap the rope end with a sheath. The rope cutting mechanism 28 includes a rope cutting blade 30, a clamping arm 31, a push-clamping mechanism 32, a limiting rod 33, and a first spring 34. The clamping arms 31 are arranged in pairs and swing on the frame 1. The rope cutting blade 30 is mounted on the clamping arm 31. The push-clamping mechanism 32 includes a roller 35 and a push plate 36. The push plate 36 is slidably mounted on the frame 1, and the roller 35 is rotatably mounted on the push plate 36. The roller 35 abuts against the outside of the clamping arm 31. After the push plate 36 slides, the two clamping arms 31 clamp or release. Both clamping arms 31 have notches. After the two clamping arms 31 are clamped, the two notches form a rope clamping space. The rope clamping space is used to position the rope. The limiting rod 33 is provided on the clamping arm 31 and is used to position the rope cutting knife 30. One end of the first spring 34 is connected to the movable end of the clamping arm 31, and the other end is connected to the frame 1. It is used to provide the force for the clamping arm 31 to swing outward.

[0067] In this embodiment, during the process of installing the handles on the tote bag, the rolled rope needs to be cut into segments. The rope is first wrapped with plastic sheeting at equal intervals by the edge-wrapping mechanism 29 to facilitate subsequent rope threading. After the plastic sheeting is completed, the rope is cut in the middle of the plastic sheeting. When the push plate 36 slides upward, it drives the roller 35 on the push plate 36 to move upward. The roller 35 abuts against the outer wall of the clamping arm 31. The upward force of the roller 35 compresses the clamping arm 31 inward, causing the two paired clamping arms 31 to swing inward and come into contact with each other. The rope-cutting blade 30 on the clamping arm 31 contacts the rope as the clamping arm 31 swings, performing a cutting action to complete the rope cutting. The sliding of the roller 35 drives the clamping arm 31 to swing, allowing the rope-cutting blade 30 to perform regular and stable cutting actions, replacing manual labor, ensuring rope cutting efficiency, and improving the flatness of the rope cut surface, thereby improving the quality of the tote bag.

[0068] After the two clamping arms 31 are clamped, the notches on the two clamping arms 31 form a rope clamping space, which is used to position the rope when cutting the rope and prevent the rope from shifting during cutting, thus affecting normal cutting. The rope cutting knife 30 is hinged in the receiving groove in the clamping arm 31, so that the rope cutting knife 30 can swing in the receiving groove, reducing the overall space occupied. The rope cutting knife 30 is set on the side of the clamping arm 31 away from the roller 35 when the roller 35 rises, so that when the roller 35 rises, it can first push the two clamping arms 31 to clamp the rope, and then push the rope cutting knife 30 to swing. This makes it convenient to position the rope before cutting, ensuring the flatness of the rope cut surface and improving the rope cutting effect.

[0069] Furthermore, it also includes,

[0070] The rope cutting mechanism 28 further includes a locking block 37, which is slidably disposed on the frame 1. The locking block 37 has a locking groove 38, and the frame 1 is provided with a boss 39. The locking groove 38 cooperates with the boss 39 to clamp the rope.

[0071] In this embodiment, the locking block 37 is vertically slidably mounted on the frame 1. During operation, the locking block 37 descends, causing the locking groove 38 to engage with the boss 39, clamping the rope and thus positioning it. This also prevents the rope end from drooping due to its own weight after the cutting action, which would affect the next action. The push plate 36 slides on the guide post, which restricts the movement direction of the push plate 36 and acts as a guide, making the sliding of the push plate 36 more stable and smooth, allowing the clamping arm 31 to clamp and facilitate cutting the rope. A check clamp is also provided on the frame 1. When the check clamp is clamped, it can clamp the rope. After the rope is cut, the rope coil will generate a force that pulls the rope backward under tension. Using the check clamp to clamp the rope can prevent the rope from being pulled back, which would prevent it from working properly and also avoid safety issues. A limiting rod 33 is installed on the inner wall of the receiving groove to limit the extreme position of the rope cutting knife 30 swinging inward, ensuring the consistency of the position of the rope cutting knife 30 in each cutting action; after the cutting action is completed, the spring retracts, so that the clamping arm 31 is reset, which facilitates the next cutting work.

[0072] Furthermore, it also includes,

[0073] The punching mechanism 2 includes a punching column 40, a sleeve 41, a second spring 42, and an upper eyelet unit 43. The punching column 40 is slidably disposed inside the sleeve 41 and punches along the axis of the punching and rope-threading hole. The sleeve 41 is slidably disposed on the frame 1 along the axis of the punching and rope-threading hole. The two ends of the second spring 42 act on the sleeve 41 and the punching column 40 respectively to provide the force for the punching column 40 to extend out of the sleeve 41. The upper eyelet unit 43 is disposed on the frame 1 and is used to fit the eyelet onto the punching column 40.

[0074] In this embodiment, the eyelet-making mechanism 2 includes a stamping column 40, a sleeve 41, a second spring 42, and an upper eyelet unit 43. The stamping column 40 is slidably disposed inside the sleeve 41, and the sleeve 41 is slidably disposed on the frame 1 along the axis of the eyelet and rope-threading hole. The two ends of the second spring 42 act on the sleeve 41 and the stamping column 40 respectively, providing force for the stamping column 40 to extend out of the sleeve 41. The upper eyelet unit 43 is disposed on the frame 1 and is used to fit the eyelet onto the stamping column 40. The sleeve 41 is slidably disposed longitudinally on a mounting bracket, which can slide laterally on the frame 1 to switch positions between the upper eyelet unit 43 and the eyelet-making station. During operation, the upper eyelet unit 43 first places the eyelet onto the stamping column 40. Then, the sleeve 41 slides with the help of the mounting bracket to a position that coincides with the axis of the eyelet and drawstring hole. Subsequently, the stamping column 40 with the eyelet is pushed towards the eyelet and drawstring hole by the cylinder. The stamping column 40 first contacts the tote bag and, together with the eyelet receiving part 5, punches a through hole in the tote bag. As the sleeve 41 continues to slide, the second spring 42 is compressed, and the sleeve 41 pushes the eyelet into the through hole. After the eyelet is punched onto the eyelet receiving part 5, it is subjected to extrusion pressure and deforms, eventually being fixed at the through hole, completing the eyelet fixing and stamping action. Then, the eyelet punching mechanism resets and performs the next action. This cycle repeats to complete the eyelet punching operation of the tote bag.

[0075] Furthermore, it also includes,

[0076] The rope threading mechanism 3 includes a second rope clamp 44, a pair of third rope clamps 45, and a second longitudinal moving frame 46. The second rope clamp 44 is slidably disposed on the frame 1, and the second longitudinal moving frame 46 is slidably disposed on the frame 1 along the longitudinal direction. The third rope clamp 45 is oscillatingly disposed on the second longitudinal moving frame 46. The third rope clamp 45 is used to thread the rope end into the drilled rope threading hole.

[0077] In this embodiment, after the eyelet stitching is completed on the tote bag, the rope threading operation is performed immediately. The rope feeding mechanism 47 delivers the handle rope to the binding mechanism 29 to cover the rigid outer layer, and then passes it through the rope cutting device 28. The rope cutting device 28 cuts the rope in the middle of the rigid outer layer, achieving rope segmentation. One end is clamped by the second rope clamp 44, which can slide on the frame 1. After the rope is wrapped, the rope is cut in the middle of the plastic outer layer. At this time, the two ends of the wrapped rope are clamped by two third rope clamps 45 respectively. Then, the two third rope clamps 45 swing on the second longitudinal moving frame 46, so that the rope end points to the axis of the eyelet stitching hole, and is then fed into the eyelet already fixed on the tote bag through the second longitudinal moving frame 46. Thus, the rope threading operation of the tote bag is completed.

[0078] Furthermore, it also includes,

[0079] The rope feeding mechanism 47 includes a second crossbeam 22 and a lifting frame 48. The second crossbeam 22 is mounted on the frame 1. A plurality of first guide wheels 49 are rotatably mounted on the second crossbeam 22. The lifting frame 48 is slidably mounted on the second crossbeam 22. A plurality of second guide wheels 50 are rotatably mounted on the lifting frame 48. The plurality of first guide wheels 49 and the plurality of second guide wheels 50 are staggered.

[0080] In this embodiment, a fourth telescopic cylinder is provided on the frame 1. The fourth telescopic cylinder drives the lifting frame 48 to slide on the frame 1. The lifting frame 48 drives the first guide wheel 49 to rise and fall. When it descends, it presses down on the bag rope between the two adjacent second guide wheels 50 and moves downward, so that the bag rope is conveyed from the bag rope unwinding reel to the rope feeding mechanism 47. The lifting frame 48 then drives the first guide wheel 49 to rise. The first guide wheel 49 disengages from the bag rope and forms a pre-feeding section of the rope at the rope feeding mechanism 47. When the clamp needs to grab and pull a section of bag rope forward, the drooping pre-feeding section of bag rope can be pulled away directly, avoiding the process of pulling directly from the unwinding reel, improving the conveying efficiency, and avoiding the resistance caused by tension when pulling the rope from affecting the rope pulling action. In addition, the pre-feeding section also has the functions of pre-storage and testing. By pressing down the rope in advance, it can detect whether the bag rope is pulled smoothly and detect problems in advance to avoid defective products.

[0081] Furthermore, it also includes,

[0082] The corn receiving component 5 includes a receiving plate 51 and a flower head receiving part 52. The receiving plate 51 is slidably disposed inside the machine head 4, and the flower head receiving part 52 is disposed on the receiving plate 51 for receiving the squeezed corn.

[0083] In this embodiment, when punching a hole, the receiving plate 51 rises, positioning the flower head receiving part 52 at the center of the hole for threading the rope. The sleeve 41 drives the stamping column 40 to approach and contact the tote bag. The flower head receiving part 52 receives the stamping column 40, causing it to press a through hole into the tote bag. As the sleeve 41 continues to slide, it pushes the eyelet on the stamping column 40, allowing the eyelet to pass through the through hole and abut against the flower head receiving part 52. The flower head receiving part 52 has multiple pressing holes. Under the action of the stamping force, the side of the eyelet that is close to the flower head receiving part 52 folds outward. The folded part of the eyelet is squeezed and formed by the multiple pressing holes on the flower head receiving part 52, thus firmly fixing the eyelet to the through hole. The flower head receiving part 52 simultaneously achieves the receiving and punching of the hole and the receiving and attaching of the eyelet, meeting the needs of fully automated multi-process processing of tote bags.

[0084] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
