Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a film bag feeding and anti-sticking mechanism. Background Technology

[0002] In the field of packaging machinery technology, film packaging bags are widely used in product packaging processes in industries such as food, daily chemicals, and pharmaceuticals due to their lightweight, low cost, and good sealing properties. However, during the production, stacking, and storage of film packaging bags, adjacent film layers are prone to sticking due to factors such as the inherent properties of the material (e.g., surface tension of the plastic film), environmental humidity, and stacking pressure.

[0003] This sticking problem causes significant problems for subsequent automated material handling operations: when traditional packaging machine material handling mechanisms (such as suction cup type and gripper type) grab film bags, they often grab multiple layers of sticky film bags at once, resulting in a decrease in material handling accuracy. This not only causes the packaging process to be interrupted, but may also increase production losses and maintenance costs due to material waste and equipment jamming. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a film bag material dispensing and anti-sticking mechanism.

[0005] This utility model proposes a film bag feeding and anti-sticking mechanism, which includes a material receiving plate. Several material blocking rods are installed on the edge of the material receiving plate. A brush and an air blowing pipe are respectively installed on the top of the material blocking rods on the same side. The brush is used to separate the sticky film packaging bags from the edge to form an opening between two adjacent layers of film packaging bags. The air blowing pipe blows air toward the opening to separate the sticky two layers of film packaging bags.

[0006] Furthermore, a vertical servo drive module is provided on the front side of the support plate. A drive plate is installed on the drive end of the vertical servo drive module. The drive plate is connected to the bottom end of the support plate to drive the support plate to rise and fall intermittently.

[0007] Furthermore, the air outlet of the air tube is configured as a flat duckbill-shaped structure.

[0008] Furthermore, the air inlet of the blowing pipe is connected to the air supply pipe, and the air inlet of the air supply pipe is connected to the air outlet of an external air supply device.

[0009] Furthermore, a regulating valve is installed in the section of the gas supply pipe to control the amount of air blown by the gas pipe.

[0010] Furthermore, a material handling module is provided on the rear side of the material support plate to remove the film packaging bags stacked on top of the material support plate one by one.

[0011] Furthermore, the material handling module includes a horizontal servo drive module. The drive end of the horizontal servo drive module is equipped with a drive base. The top of the drive base is equipped with a lifting drive cylinder. The telescopic end of the lifting drive cylinder extends to the bottom of the drive base and is equipped with a base. Several suction nozzles are installed inside the base.

[0012] Furthermore, several guide rods are slidably connected inside the drive seat, and the bottom ends of the guide rods are connected to the base together.

[0013] The beneficial effects of this utility model are as follows: By setting a brush and an air blowing pipe at the top of the baffle rod on the same side of the material receiving plate, the brush combs the sticky film bags from the edge to form an opening, and the air blowing pipe blows air into the opening to achieve layer separation. In conjunction with the vertical servo drive module to drive the material receiving plate to intermittently rise and fall to ensure stable material picking height, and the material picking module to accurately adsorb and pick up materials, the sticking problem when film bags are stacked can be effectively solved, avoiding the situation of "over-picking" by the material picking mechanism. At the same time, no manual assistance is required, which greatly improves the accuracy and efficiency of automated material picking, reduces packaging process interruption, material waste and equipment jamming caused by sticking, adapts to the operation requirements of high-speed automated packaging production lines, and reduces production losses and maintenance costs.

[0016] Reference Figure 1-4 The present invention proposes a film bag picking and anti-sticking mechanism, including a material support plate 1. Several film packaging bags 9 to be picked are stacked on the upper part of the material support plate 1. Several material blocking rods 2 are evenly installed at the edge of the material support plate 1. These material blocking rods 2 are vertically distributed and can play a lateral limiting role on the film packaging bags 9 stacked on the material support plate 1, effectively preventing the film packaging bags 9 from slipping due to positional displacement during lifting and picking, and ensuring the neatness of the material stacking. To achieve the anti-sticking function of the film packaging bag 9, a brush 3 and an air blowing pipe 4 are respectively installed on the top of the baffle bar 2 on the same side of the material receiving plate 1. The two form a cooperative anti-sticking combination structure. The bristles of the brush 3 face the edge of the stacked film packaging bags 9. Its main function is to comb and separate the initially stuck adjacent layers of film packaging bags 9 from the edge of the film packaging bag 9 through physical contact, forming a tiny opening between the two layers of film. The air blowing pipe 4 is precisely aligned with the opening. It blows air into the opening through the airflow, and uses the thrust of the airflow to further expand the tiny opening, ultimately achieving complete separation of the stuck two layers of film packaging bags 9, avoiding the phenomenon of taking too much material during subsequent material handling. In order to improve the blowing efficiency and airflow concentration, the air outlet of the air blowing pipe 4 is set as a flat duckbill-shaped structure. This structure can make the airflow act more concentrated on the opening of the film. Compared with the round air outlet, it can reduce airflow dispersion and further optimize the separation effect. At the air inlet of the air blowing pipe 4, an air supply pipe 8 is also connected. The other end of the air supply pipe 8 is connected to the air outlet of an external air supply device (such as an air compressor) to provide a continuous and stable air source for the air blowing pipe 4. At the same time, a regulating valve 10 is installed in the middle section of the air supply pipe 8. The operator can control the airflow rate through the air supply pipe 8 into the air blowing pipe 4 by adjusting the valve opening of the regulating valve 10. In this way, the air volume can be flexibly adjusted according to the material thickness and adhesion of the film packaging bag 9, so as to ensure the separation effect and avoid the film packaging bag 9 from being stacked and scattered due to excessive air volume. To meet the height requirements of the material handling operation, a vertical servo drive module 5 is installed on the front side of the material support plate 1. This module is driven by a servo motor and has high-precision position control capability. A drive plate 7 is fixedly installed on the drive end (such as the slider of a ball screw) of the vertical servo drive module 5. The top of the drive plate 7 is fixedly connected to the bottom edge of the material support plate 1. When the vertical servo drive module 5 is started, its drive end will drive the drive plate 7 to perform intermittent lifting and lowering movements, thereby synchronously driving the material support plate 1 and the film packaging bags 9 stacked above it to intermittently lift and lower. As the material handling module 6 continuously removes the top layer film packaging bags 9, the material support plate 1 can compensate for the height difference by intermittently rising, ensuring that the top layer film packaging bags 9 are always within the effective material handling range of the material handling module 6 during each material handling, thereby improving material handling efficiency and stability. On the rear side of the support plate 1, a material picking module 6 is correspondingly provided. Its function is to pick up the stacked film packaging bags 9 on the support plate 1 one by one, completing the automated material picking operation. The material picking module 6 is specifically composed of a horizontal servo drive module 61, a drive base 62, a lifting drive cylinder 63, a base 64, a suction nozzle 65, and a guide rod 66. Among them, the horizontal servo drive module 61 is installed horizontally, and its drive end (such as the slide of a linear guide rail) is fixedly connected to the bottom end of the drive base 62, which can drive the drive base 62 to move in the horizontal direction (towards or away from the support plate 1). At the top of 2, a lifting drive cylinder 63 is vertically installed. The telescopic end of the cylinder extends through the drive seat 62 to its lower part and is fixedly connected to the center of the top of the base 64. The base 64 can be driven to move vertically up and down by the telescopic movement of the piston rod of the lifting drive cylinder 63. Several suction nozzles 65 are evenly installed inside the base 64. The suction end of the suction nozzle 65 faces downward and is connected to the external negative pressure equipment through an air pipe. When the suction nozzle 65 contacts the top film packaging bag 9, the negative pressure equipment is activated, and the suction nozzle 65 generates suction to adsorb and fix the film packaging bag 9, realizing the material picking action. To ensure the stability of the base 64 during the lifting process and to prevent tilting after the suction nozzle 65 adsorbs material, several guide rods 66 are slidably connected inside the drive base 62. These guide rods 66 are symmetrically distributed on both sides of the lifting drive cylinder 63, and the bottom ends of the guide rods 66 are fixedly connected to the top edge of the base 64. When the lifting drive cylinder 63 drives the base 64 to lift, the guide rods 66 will slide synchronously along the sliding holes of the drive base 62, guiding and limiting the movement trajectory of the base 64, effectively preventing the base 64 from shifting or shaking during the lifting process, and ensuring that the suction nozzle 65 can be accurately aligned with the top film packaging bag 9.

[0017] The complete workflow of this organization is as follows: First, the film packaging bags 9 to be picked up are neatly stacked on the receiving plate 1, and the baffle rod 2 limits their lateral movement. Then, the vertical servo drive module 5 is activated, driving the receiving plate 1 to rise to the initial picking height. Next, the horizontal servo drive module 61 drives the drive base 62 to move above the receiving plate 1, and the lifting drive cylinder 63 drives the base 64 to descend. The suction nozzle 65 contacts the top layer of film packaging bags 9 and generates negative pressure adsorption. At the moment the film packaging bags 9 are adsorbed and lifted, the bristles of the brush 3 will generate resistance on the top and second layers of film packaging bags 9. Resistance acts on the edges of the top and second layer film packaging bags 9, causing an opening to be separated between the top and second layer film packaging bags 9. The air blowing pipe 4 blows air into the opening to completely separate the two layers of film. The lifting drive cylinder 63 drives the base 64 to rise, and the horizontal servo drive module 61 then drives the drive seat 62 to move to the designated unloading position. The suction nozzle 65 releases negative pressure to complete the unloading. As the top layer film packaging bag 9 is removed, the vertical servo drive module 5 drives the material support plate 1 to rise intermittently, repeating the above anti-sticking and material picking actions to achieve continuous automated film bag picking operation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
