Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, specifically to a bagging machine with a rope collection function. Background Technology

[0002] In the field of packaging machinery, bagging machines are widely used in automated operations of filling and sealing materials into packaging bags. For materials such as tote bags with drawstrings, after being filled into the packaging bag, the drawstrings are often distributed haphazardly on the tongue, outside the tongue, and at the bag opening. This can cause the drawstrings to be exposed, folded into the seal, or affect the flatness of the seal during subsequent sealing, thus reducing the sealing quality and the appearance of the finished product.

[0003] In existing technologies, bagging machines typically only include a conveying mechanism, a bagging mechanism, and a sealing mechanism, lacking a dedicated mechanism for organizing and collecting the drawstrings of handbags. Operators often need to manually organize and collect the drawstrings before sealing, which is not only inefficient but also makes it difficult to guarantee the accuracy and consistency of manual organization. Although some existing equipment has structures that use brushes or levers to adjust the posture of materials, these structures are mostly used for material sorting, surface cleaning, or position correction, and do not provide any technical guidance or inspiration for the directional collection of drawstrings at the bag opening.

[0004] In addition, the spatial layout between the sealing mechanism and the folding plate in existing bagging machines lacks a systematic and coordinated design. The stability of the packaging bag's tongue before sealing is insufficient, which can easily lead to misalignment of the seal or incomplete folding of the tongue, further affecting the sealing quality. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned deficiencies in the existing technology and provide a bagging machine with a rope collection function. After the tote bag is put into the packaging bag and before sealing, the scattered ropes can be automatically collected at the opening of the packaging bag and the ropes can be aligned in the same direction, thereby improving the sealing quality and the appearance of the finished product, reducing manual intervention and improving the degree of automation.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A bagging machine with a rope collection function includes a conveying mechanism and a bagging mechanism and a sealing mechanism arranged sequentially along the conveying direction of the conveying mechanism. It also includes a rope collection mechanism, which is disposed between the bagging mechanism and the sealing mechanism. The rope collection mechanism includes at least one actuating element, which is disposed directly above the side of the conveying mechanism and is located on the travel path of the rope at the bag opening.

[0007] The rope and strap collection mechanism allows the agitator to gather the scattered ropes and straps at the bag opening as the bag is being transported, ensuring that the ropes and straps are aligned with the bag-packing mechanism and collected at the bag opening. This process organizes the ropes and straps before sealing, improving sealing quality and the appearance of the finished product while reducing manual intervention.

[0008] Preferably, the actuating element is made of a flexible material, and the rope collection mechanism further includes an actuating head, on which the actuating element is mounted. By setting the actuating element to a flexible material, preferably a brush, its flexibility ensures that the surface of the rope or packaging bag will not be damaged during the actuation process. At the same time, the multi-bristle structure of the brush can effectively contact and guide the rope to complete the collection action.

[0009] Preferably, the rope collection mechanism further includes a toggle drive component that drives the toggle head to rise and fall. The toggle drive component, after descending with the toggle head, is positioned on the rope's travel path at the bag opening. By setting the toggle drive component to drive the toggle head to rise and fall, independent movement control of the toggle head for each bag is achieved. When a bag reaches the toggle head position, the toggle head moves down to collect the bag, and rises back to its original position after collection, thus avoiding continuous interference from the toggle drive component with the subsequent bag transport.

[0010] Preferably, the system also includes a folding plate, located between the bagging mechanism and the sealing mechanism, and the drawstring collection mechanism is disposed between the folding plate and the bagging mechanism. By positioning the folding plate downstream of the drawstring collection mechanism, the flap of the packaging bag is folded upwards again after the drawstrings are collected, avoiding interference with the collected drawstrings or folding the drawstrings into the bag during flap folding.

[0011] Preferably, the folding plate has a smoothly transitioning guide surface on one end facing the bag-covering mechanism, and the downstream portion of the folding plate extends to the lower side of the sealing mechanism, with a clearance opening at the top of the downstream portion. By providing a smoothly transitioning guide surface, a downstream extension, and a clearance opening on the folding plate, the tongue of the packaging bag can be smoothly guided and folded, and stably supported by the folding plate before sealing. At the same time, the clearance opening provides movement space for the sealing push plate, avoiding structural interference.

[0012] Preferably, the sealing mechanism includes a sealing push plate and a sealing drive component that drives the sealing push plate to translate horizontally above the conveying mechanism. The lower end of the sealing push plate is provided with a flexible sealing component, and the sealing push plate is located at the clearance opening of the folding plate. By placing the sealing push plate at the clearance opening of the folding plate, the tongue is supported by both the folding plate and the sealing push plate before sealing. When the sealing push plate translates, it pushes the tongue to complete the folding and sealing process, improving the stability and accuracy of the sealing action.

[0013] Preferably, the system also includes a bag-pressing mechanism, which includes a bag-pressing plate that is vertically adjustable via a first driving component. By setting the bag-pressing plate to press down on the packaging bag before sealing, the packaging bag is prevented from shifting during the sealing process, ensuring the accuracy of the sealing position and the tightness of the packaging.

[0014] Preferably, the bag-pressing mechanism further includes two bag-pressing strips, which are respectively arranged on the front and rear sides of the sealing mechanism along the conveying direction. Each bag-pressing strip is opened and closed along the conveying direction by a second driving member, and each bag-pressing strip is independently equipped with a third driving member to drive its lifting and lowering. By setting two bag-pressing strips to press down on both sides of the bag opening before sealing and to separate them along the conveying direction during sealing, the bag opening is fixed during the sealing process without affecting the folding action of the tongue, thereby improving the sealing quality and the consistency of the finished product.

[0015] Preferably, the conveying mechanism is a conveyor belt with a built-in suction component. The surface of the conveyor belt is provided with suction holes, and the suction component adsorbs the packaging bag onto the surface of the conveyor belt. By using a conveyor belt with a built-in suction component, the packaging bag is stably adsorbed onto the surface of the conveyor belt, avoiding the offset and slippage of the packaging bag during the conveying process, and ensuring the positioning accuracy of the rope collection and sealing actions.

[0018] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0019] Example: Figures 1 to 4 The bagging machine shown includes a conveying mechanism 1, a bagging mechanism 2, a sealing mechanism 3, a rope collection mechanism 4, a bag folding plate 5, and a bag pressing mechanism 6.

[0020] The conveying mechanism 1 uses a conveyor belt 11 with a built-in suction component 13. The surface of the conveyor belt 11 is provided with multiple suction holes 12. The suction component 13 can be a negative pressure generating device such as a centrifugal fan or a vacuum pump. The suction component 13 is connected to the suction chamber below the conveyor belt 11 through a pipeline, so that negative pressure is generated at the suction holes 12, which adsorbs the packaging bag 7 onto the surface of the conveyor belt 11 and prevents the packaging bag 7 from shifting or sliding during the conveying process.

[0021] As an alternative implementation, the conveying mechanism 1 can also be a conventional belt conveyor or chain conveyor without the suction adsorption function. However, the conveyor belt 11 with built-in suction element 13 is the preferred option, which can effectively prevent the packaging bag 7 from shifting during the conveying, rope collection and sealing process.

[0022] The bagging mechanism 2 is located on one side of the starting end of the conveying mechanism 1. The bagging mechanism 2 is a conventional bagging device in the prior art, used to put the tote bag 8 with drawstring 81 into the packaging bag 7. The specific structure and working principle of the bagging mechanism 2 are common knowledge in the art and will not be described in detail here. After the bagging mechanism 2 completes the bagging, the packaging bag 7 containing the tote bag 8 continues to be conveyed forward with the conveying mechanism 1. At this time, the drawstring 81 of the tote bag 8 is randomly distributed on the tongue 71, the outside of the tongue 71, and the opening 72 of the packaging bag 7.

[0023] A rope collection mechanism 4 is positioned between the bagging mechanism 2 and the sealing mechanism 3. The rope collection mechanism 4 includes a toggle head 41 and a toggle drive 43 that drives the toggle head 41 to move up and down. The toggle head 41 is positioned directly above the side of the conveying mechanism 1, its lateral position corresponding to the opening 72 of the packaging bag 7. The lower end of the toggle head 41 has a toggle element 42, which is a flexible brush. The toggle drive 43 is preferably a cylinder.

[0024] When the packaging bag 7 containing the tote bag 8 is conveyed to the position of the rope collection mechanism 4, the actuating drive 43 drives the actuating head 41 to move downward. The actuating element 42, following the descent of the actuating head 41, is positioned on the path of the rope 81 at the bag opening 72 of the packaging bag 7. At this time, a gap is left between the lower end of the actuating element 42 and the conveyor belt 11 for the tongue to pass through. As the conveying mechanism 1 continues to move the packaging bag 7 towards the sealing mechanism 3, relative movement occurs between the actuating element 42 and the rope 81. The actuating element 42 moves the ropes 81 scattered on the tongue 71 and outside the tongue 71 towards the bag-covering mechanism 2, so that the ropes 81 are uniformly collected at the bag opening 72 of the packaging bag 7, with the ropes 81 facing the same direction. After collection, the actuating drive 43 drives the actuating head 41 to rise and reset, awaiting the arrival of the next packaging bag 7.

[0025] It should be noted that in this embodiment, the actuating head 41 adopts a passive working mode, that is, the actuating element 42 relies on the relative motion of the packaging bag 7 as it moves forward with the conveying mechanism 1 to collect the rope 81, and the actuating element 42 itself does not perform active movement. As an alternative implementation, the actuating head 41 can also adopt an active working mode, that is, while the actuating drive element 43 drives the actuating head 41 to rise and fall, or independently of the rising and falling action, an additional reciprocating drive element (such as a crank connecting rod mechanism, eccentric wheel mechanism, or servo motor drive, etc.) is configured for the actuating head 41, so that the actuating element 42 generates reciprocating oscillation along the conveying direction during the rising and falling process or after it has descended to the position, further improving the collection efficiency and collection effect of the rope 81.

[0026] As an alternative implementation, the number of actuating heads 41 can be flexibly set according to the width of the bag opening 72 of the packaging bag 7. When the width of the bag opening 72 of the packaging bag 7 is large, two or more actuating heads 41 can be arranged laterally along the bag opening 72, and each actuating head 41 is independently equipped with an actuating drive 43 to cover the entire width area of ​​the bag opening 72, ensuring that all the ropes 81 are effectively collected. When the width of the bag opening 72 is small, only one actuating head 41 with a width adapted to the bag opening 72 can be provided.

[0027] As an alternative implementation, the flexible sealing element 33 and the actuating element 42 are not limited to a brush, but can also be made of silicone strips, rubber strips, sponge strips or other soft materials with flexibility and elasticity, as long as they can achieve flexible actuation of the cord 81 and flexible pushing of the tongue 71.

[0028] The folding plate 5 is positioned between the bagging mechanism 2 and the sealing mechanism 3, and is located downstream of the rope collecting mechanism 4; that is, the rope collecting mechanism 4 is positioned between the folding plate 5 and the bagging mechanism 2. The folding plate 5 is a fixed structure, fixedly installed on the frame. The end of the folding plate 5 facing the bagging mechanism 2 has a smoothly transitioning guide surface 51. The downstream portion of the folding plate 5 extends to the lower side of the sealing mechanism 3, and the top of this downstream portion has a clearance opening 52.

[0029] After being collected by the rope collection mechanism 4, the packaging bag 7 continues to be conveyed forward. Its tongue 71 first contacts the guide surface 51 of the folding plate 5, is smoothly and gradually lifted, and finally naturally transitions to the top of the folding plate 5, completing the upward bend. After bending, the tongue 71 forms an angle of approximately 90 degrees with the conveying plane of the conveying mechanism 1. The tongue 71 is supported by the folding plate 5 after bending. When the packaging bag 7 is conveyed to the sealing mechanism 3, the tongue 71 is jointly supported by the folding plate 5 and the sealing push plate 31 located at the clearance opening 52 of the folding plate 5.

[0030] The sealing mechanism 3 is located downstream of the folding bag plate 5. The sealing mechanism 3 includes a sealing push plate 31 and a sealing drive component 32 that drives the sealing push plate 31 to translate horizontally on the upper side of the conveying mechanism 1. A flexible sealing component 33 is provided at the lower end of the sealing push plate 31. The flexible sealing component 33 is preferably made of a soft material such as a sealing brush; in this embodiment, a sealing brush is used. The sealing drive component 32 is preferably a cylinder. The sealing push plate 31 is located at the clearance opening 52 of the folding bag plate 5.

[0031] During sealing, the tongue 71 of the packaging bag 7 has been pre-coated with adhesive or double-sided tape before being bagged. The sealing drive 32 drives the sealing push plate 31 to move horizontally, and the flexible sealing component 33 at the lower end of the sealing push plate 31 pushes the tongue 71 of the packaging bag 7 to fold towards the bag body of the packaging bag 7 until the tongue 71 is pasted to the bag opening 72 of the packaging bag 7, completing the sealing action.

[0032] The bag-pressing mechanism 6 is located above the conveying mechanism 1, at the position of the sealing mechanism 3. The bag-pressing mechanism 6 includes a bag-pressing plate 61 and two bag-pressing strips 63. The bag-pressing plate 61 is vertically adjustable via a first driving member 62, which is either a pneumatic cylinder or an electric cylinder. The size and position of the bag-pressing plate 61 are configured so that after it descends, it presses down on the middle of the packaging bag 7 to the end furthest from the bag opening 72, i.e., the area in the bottom direction of the bag, thus compacting the material inside the packaging bag 7.

[0033] Two bag-pressing strips 63 are respectively arranged on the front and rear sides of the sealing mechanism 3 along the conveying direction. Each bag-pressing strip 63 is opened and closed along the conveying direction by a second driving member 64, and each bag-pressing strip 63 is independently equipped with a third driving member 65 to drive its lifting and lowering. The second driving member 64 is preferably a cylinder. The third driving member 65 can be a cylinder or an electric cylinder.

[0034] The specific timing of the sealing action is as follows: When the packaging bag 7 containing the tote bag 8 is conveyed to the sealing mechanism 3, the first driving member 62 drives the bag pressing plate 61 to move down and press down on the bag body of the packaging bag 7; the third driving member 65 drives the two bag pressing strips 63 to move down and press down on the bag opening 72 of the packaging bag 7; then the sealing driving member 32 drives the sealing push plate 31 to move horizontally, and the flexible sealing member 33 on the sealing push plate 31 pushes the tongue 71 of the packaging bag 7 to bend over from the upper side of the bag pressing strip 63 until the tongue 71 is pasted on the bag opening 72 of the packaging bag 7; then the second driving member 64 drives the two bag pressing strips 63 to move away from each other along the conveying direction and pull them away from the bag opening 72 and the tongue 71 of the packaging bag 7. Finally, the bag pressing plate 61 and the bag pressing strips 63 return to their initial positions, completing one sealing cycle.

[0035] During the above-mentioned actions, the timing coordination between the lifting and lowering actions of the bag pressing plate 61 and the bag pressing strip 63 and the translating action of the sealing push plate 31 can be uniformly controlled by a programmable logic controller. Each driving component is electrically connected to the programmable logic controller to achieve automated collaborative operation.

[0036] As an alternative implementation, the bag-pressing mechanism 6 can be omitted. If the conveying stability of the packaging bag 7 is high or the material inside the packaging bag 7 has sufficient self-weight, the suction force of the conveying mechanism 1 alone can ensure the stability of the packaging bag 7 during the sealing process. However, setting the bag-pressing mechanism 6 is the preferred solution, as it can more reliably guarantee the sealing quality.

[0037] As an alternative implementation, the toggle drive 43, sealing drive 32, first drive 62, second drive 64 and third drive 65 are not limited to cylinders, and may also be linear drive devices known in the art such as hydraulic cylinders, electric push rods, lead screw stepper motors, gear rack mechanisms or cam mechanisms.

[0038] The working process of this embodiment is as follows: The packaging bag 7 is placed on the conveying mechanism 1, and the negative pressure generated by the suction component 13 adsorbs the packaging bag 7 onto the surface of the conveyor belt 11; the packaging bag 7 moves forward with the conveyor belt 11 to the bagging mechanism 2, and the bagging mechanism 2 puts the tote bag 8 with the drawstring 81 into the packaging bag 7; the packaging bag 7 containing the tote bag 8 continues to move forward to the drawstring collection mechanism 4, the agitator head 41 moves down, and the agitator component 42 agitates and collects the scattered drawstrings 81 of the tote bag 8, and collects the drawstrings 81 uniformly at the bag opening 72 with the same orientation; the collection is completed. The rear actuating head 41 rises and resets; the packaging bag 7 continues to move forward, and the tongue 71 is gradually lifted and bent upward by the guide surface 51 of the folding bag plate 5, supported by the folding bag plate 5; when the packaging bag 7 reaches the sealing mechanism 3, the pressing plate 61 moves down to press the bag body, the two pressing strips 63 move down to press the bag opening 72, the sealing push plate 31 moves horizontally to push the tongue 71 to fold over from the upper side of the pressing strips 63 and stick to the bag opening 72, the pressing strips 63 separate and are pulled away, all parts reset, and the sealing is completed; the sealed packaging bag 7 continues to be transported to the next station by the conveying mechanism 1.
