Description

Technical Field

[0001] This invention relates to the technical field of bag processing equipment, and more specifically, to an automatic bag stacking device. Background Technology

[0002] Storage bags are a common type of bag on the market. They generally consist of a bag body and a drawstring. The bag body has an opening on one side, and the middle of the drawstring is threaded through the opening of the bag body. At the same time, the two ends of the drawstring protrude from the surface of the bag body. By pulling the drawstring to both sides, the opening of the bag body can be tightened to achieve storage.

[0003] Compared to ordinary bags, storage bags are more complicated to manufacture due to the presence of storage ropes. Especially after the initial production is completed and packaging is required, the storage ropes are often offset relative to the bag body. This not only affects the efficiency of subsequent packaging and sorting but may also cause inconvenience to users and affect product quality. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art where, during the packaging process after production and processing, the storage rope is offset relative to the bag body, which interferes with the packaging efficiency, may cause inconvenience to users, and affects product quality.

[0005] To address the aforementioned problems, this invention provides an automatic bag stacking device, including a base, a bag guide assembly, a rope guide assembly, and a traction power component. The base is provided with a support plate. The rope guide assembly includes a first guide rod and a second guide rod, each including a driving end slidably connected to the support plate and a limiting end for attaching the rope. The bag guide assembly is located between the first and second guide rods, and includes a first guide plate and a second guide plate. Each guide plate includes a driving portion slidably connected to the support plate and a limiting portion for attaching the bag body. The traction power component is used to adjust the distance between the first guide rod and the second guide rod, and the distance between the first guide plate and the second guide plate.

[0006] In the above solution, the limiting parts of the first and second guide plates are inserted into the bag body, while the limiting ends of the first and second guide rods are passed through both ends of the bag's storage rope. Driven by the traction power component, the first and second guide plates separate, and the first and second guide rods separate, causing both the bag body and the storage rope to be pulled to both sides, thus correcting the position of the storage rope relative to the bag body. Compared with existing technologies, the advantages of this solution are automatic bag organization, effective solution to the problem of misalignment of the storage rope in existing bags, and convenient subsequent packaging operations, demonstrating good practicality.

[0007] Preferably, the support plate is rotatably connected to the base, and the side of the support plate is provided with multiple guide portions, each of which is equipped with a bag guide assembly, a rope guide assembly, and a traction power component. This allows the support plate to simultaneously organize multiple storage bags, further improving efficiency.

[0008] Preferably, the base is also equipped with a rotary motor and a position sensor. The rotary motor is used to drive the support disk to rotate, and the support disk is equipped with a trigger sensor for matching the position sensor, thereby realizing the automatic rotation of the support disk relative to the base, further improving the level of automation. The setting of the position sensor and the trigger sensor ensures the positional accuracy of the support disk relative to the base, which facilitates subsequent packaging operations.

[0009] Preferably, the guide portion includes a guide shaft arranged circumferentially along the support plate and a mounting seat connected to the middle of the guide shaft. The driving end of the first guide rod and the driving part of the first guide plate are slidably connected to the left side of the guide shaft, and the driving end of the second guide rod and the driving part of the second guide plate are slidably connected to the right side of the guide shaft. The traction power component is connected to the mounting seat. With this structure, the bag guide assembly and the rope guide assembly can more stably organize the bag body and the rope of the storage bag, and operate reliably.

[0010] Preferably, the traction power component includes a first cylinder connected to the first guide plate and a second cylinder connected to the second guide plate. The first guide rod is connected to the left side of the first guide plate, and the second guide rod is connected to the right side of the second guide plate. Thus, under the drive of the first and second cylinders, the distance between the first and second guide plates, and between the first and second guide rods, can be freely adjusted.

[0011] Preferably, the mounting base is provided with an air nozzle for blowing air on one side facing the limiting end of the first guide plate or the limiting end of the second guide plate, thereby realizing the blowing of air onto the bag body of the storage bag and avoiding the bag body from folding or wrinkling.

[0012] Preferably, the base is further provided with a bag stacking module and a storage area. The bag stacking module includes a clamping assembly and a bag pressing assembly. The clamping assembly includes a gripper and a transfer power component for driving the gripper to move between the storage area and the support plate. The bag pressing assembly is located above the storage area. The bag pressing assembly includes a pressure plate and a bag pressing power component for driving the pressure plate to move toward the storage area. Thus, the clamping assembly can automatically clamp and transfer the storage bags on the support plate to the storage area, while the bag pressing assembly can press the storage bags in the storage area together, making the stacking of the storage bags more compact and neat.

[0013] Preferably, the transfer power component includes a slide rail arranged laterally and a slide block slidably connected to the slide rail, and the gripper is connected to the slide block; the bag pressing power component is a downwardly arranged lifting cylinder, and the pressing plate is connected to the lifting cylinder.

Detailed Implementation

[0022] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention. It should also be noted that all directional indications (such as up, down, left, right, front, back, inside, outside) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0023] Please see Figures 1-6 An embodiment of the present invention provides an automatic bag stacking device, including a base 1, a bag guide assembly 3, a rope guide assembly 4, and a traction power component 5. A support plate 2 is provided on the base 1. The rope guide assembly 4 includes a first guide rod 4.1 and a second guide rod 4.2. Both the first guide rod 4.1 and the second guide rod 4.2 include a driving end slidably connected to the support plate 2 and a limiting end for attaching the rope. The bag guide assembly 3 is located between the first guide rod 4.1 and the second guide rod 4.2. The bag guide assembly 3 includes a first guide plate 3.1 and a second guide plate 3.2. Both the first guide plate 3.1 and the second guide plate 3.2 include a driving part slidably connected to the support plate 2 and a limiting part for attaching the bag body. The traction power component 5 is used to adjust the distance between the first guide rod 4.1 and the second guide rod 4.2, and the distance between the first guide plate 3.1 and the second guide plate 3.2.

[0024] In use, the limiting portions of the first guide plate 3.1 and the second guide plate 3.2 are inserted into the bag body of the storage bag, while the limiting ends of the first guide rod 4.1 and the second guide rod 4.2 are passed through both ends of the storage rope of the storage bag. Driven by the traction power component 5, the first guide plate 3.1 and the second guide plate 3.2 separate, as do the first guide rod 4.1 and the second guide rod 4.2. This causes both the bag body and the storage rope to be pulled to both sides, achieving the function of correcting the position of the storage rope relative to the bag body. Compared with the prior art, the beneficial effects of the above solution are that it achieves automatic sorting of the storage bag, effectively solves the problem of misalignment of the storage rope in existing storage bags, facilitates subsequent packaging operations, and has good practicality.

[0025] In this embodiment, the support disk 2 is rotatably connected to the base 1, and the base 1 is equipped with a rotary motor 1.1 and a position sensor 1.2. The rotary motor 1.1 is arranged vertically, thereby driving the support disk 2 to rotate in the horizontal direction, thus realizing the automatic rotation of the support disk 2 relative to the base 1 and effectively improving the level of automation.

[0026] Furthermore, the support plate 2 is equipped with several trigger sensors 2.4 arranged circumferentially. When the position sensor 1.2 on the base 1 is opposite to the trigger sensor 2.4, the position of the guide bag assembly 3 on the support plate 2 relative to the base 1 can be determined, which facilitates subsequent packaging operations.

[0027] As an improvement to the above embodiment, the side of the support plate 2 is provided with multiple guide parts, each of which is provided with a bag guide assembly 3, a rope guide assembly 4 and a traction power component 5, so that the support plate 2 can sort multiple storage bags at the same time, effectively improving efficiency.

[0028] The guide section includes a guide shaft 2.1 arranged circumferentially along the support plate 2 and a mounting base 2.2 connected to the middle of the guide shaft 2.1. The driving end of the first guide rod 4.1 and the driving part of the first guide plate 3.1 are slidably connected to the left side of the guide shaft 2.1, and the driving end of the second guide rod 4.2 and the driving part of the second guide plate 3.2 are slidably connected to the right side of the guide shaft 2.1. The traction power component 5 is connected to the mounting base 2.2. With this structure, the bag guide assembly 3 and the rope guide assembly 4 can more stably organize the bag body and the rope of the storage bag, and operate reliably.

[0029] In this embodiment, the traction power component 5 includes a first cylinder 5.1 connected to the first guide plate 3.1 and a second cylinder 5.2 connected to the second guide plate 3.2. A first guide rod 4.1 is connected to the left side of the first guide plate 3.1, and a second guide rod 4.2 is connected to the right side of the second guide plate 3.2. Therefore, under the drive of the first cylinder 5.1 and the second cylinder 5.2, the distance between the first guide plate 3.1 and the second guide plate 3.2, and between the first guide rod 4.1 and the second guide rod 4.2, can be freely adjusted. It should be understood that the first cylinder 5.1 and the second cylinder 5.2 can also be replaced with other common power devices, such as electric cylinders, hydraulic cylinders, etc.; and the first cylinder 5.1 can also be connected to the first guide rod 4.1, and the second cylinder 5.2 can also be connected to the second guide rod 4.2, which can also achieve free adjustment of the distance between the first guide plate 3.1 and the second guide plate 3.2, and between the first guide rod 4.1 and the second guide plate 3.2; in addition, the first guide rod 4.1 and the second guide plate 3.2, and the second guide rod 4.2 and the second guide plate 3.2 can also be independent of each other, and the traction power component 5 consists of four independent cylinders, so that the four independent cylinders drive the first guide rod 4.1, the second guide rod 4.2, the first guide plate 3.1 and the second guide plate 3.2 respectively, which is also part of this design concept.

[0030] The long sides of the first guide rod 4.1 and the second guide rod 4.2 are both perpendicular to the guide shaft 2.1, and the long sides of the first guide plate 3.1 and the second guide plate 3.2 are also perpendicular to the guide shaft 2.1, thus facilitating the insertion of the bag body and the storage rope.

[0031] As an improvement to the above embodiment, the mounting base 2.2 is provided with an air nozzle 2.3 for blowing air on one side facing the limiting end of the first guide plate 3.1 or the second guide plate 3.2, so as to realize the blowing of air on the bag body of the storage bag and avoid the bag body from folding or wrinkling.

[0032] As an extension of the above embodiment, the base 1 is further provided with a bag stacking module and a storage area 1.3. The bag stacking module includes a clamping component 6 and a bag pressing component 7. The clamping component 6 is located on the left side of the storage area 1.3, and the bag stacking module is located on the right side of the storage area 1.3. The clamping component 6 includes a gripper 6.1 and a transfer power component for driving the gripper 6.1 to move between the storage area 1.3 and the support plate 2. The transfer power component includes a slide rail 6.2 arranged laterally and a slide block 6.3 slidably connected to the slide rail 6.2. The slide block 6.3 can be driven by a cylinder or an electric cylinder. The gripper 6.1 is connected to the lower side of the slide block 6.3. The gripper 6.1 can be opened and closed by a cylinder to clamp the storage bags on the support plate 2.

[0033] The bag-pressing assembly 7 is located above the storage area 1.3. The bag-pressing assembly 7 includes a pressure plate 7.1 and a bag-pressing power component for driving the pressure plate 7.1 to move towards the storage area 1.3. This allows the clamping assembly 6 to automatically clamp and transfer the storage bags on the support plate 2 to the storage area 1.3, while the bag-pressing assembly 7 presses the storage bags in the storage area 1.3 together, resulting in a tighter and neater stacking of the storage bags. In this embodiment, the bag-pressing power component is a downward-facing lifting cylinder 7.2, and the pressure plate 7.1 is connected to the lifting cylinder 7.2.

[0034] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art will recognize that various changes and modifications can be made without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
