Description

Technical Field

[0001] This utility model belongs to the field of packaging machinery technology, specifically relating to a high-efficiency film bag feeding device. Background Technology

[0002] On automated packaging lines in industries such as food, daily chemicals, and pharmaceuticals, pre-made film bags (such as stand-up pouches, back-seal bags, and three-side seal bags) often need to be fed one by one to the bag opening and filling stations. Currently, many production lines still use manual feeding, which is labor-intensive, inefficient, and prone to contaminating packaging materials.

[0003] Many existing automatic feeding devices use suction cups to directly pick up the top layer of bags. However, because film bags are lightweight, thin, and soft, and are easily stuck together due to static electricity and vacuum effects when stacked, problems often arise during suction, such as picking up multiple bags at once, the suction nozzle failing to pick up the bags due to slippage, or even tearing the bags. This results in a low feeding success rate and seriously affects the efficiency and stability of automated production lines.

[0004] Therefore, there is an urgent need for a new type of device that can effectively overcome film bag adhesion and achieve stable and reliable separation and feeding.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0022] like Figures 1-4As shown, an embodiment of the present invention provides a high-efficiency film bag feeding device, including a feeding mechanism 1 and a separation mechanism 2. The feeding mechanism 1 includes a main body assembly, a storage assembly mounted on the main body assembly, and a driving assembly for driving the storage assembly to feed materials. The main body assembly includes a base plate 11 and a pair of side plates 12 fixedly connected to the left and right side walls of the base plate 11. The storage assembly includes a storage platform 13, which is installed between the pair of side plates 12 in a vertically movable manner. The separation mechanism 2 includes a negative pressure adsorption separation assembly and a positive pressure blowing assembly. The negative pressure adsorption separation assembly includes an adsorption plate 21 that reciprocates between the pair of side plates 12 and a plurality of suction nozzles 23 opened at the bottom of the adsorption plate 21. The positive pressure blowing assembly includes a blowing tube 25 that reciprocates with the adsorption plate 21, and a plurality of blowing nozzles 26 are opened on the side wall of the blowing tube 25.

[0023] When using this high-efficiency film bag feeding device, a certain number of film bag stacks are stored on the storage platform 13. Then, the storage platform 13 is lifted between a pair of side plates 12 by the drive component, thereby conveying the film bags to the feeding position by lifting the storage platform 13. The movement of the negative pressure adsorption separation component drives the positive pressure blowing component to move to the film bag position near the feeding side. Multiple blowing nozzles 26 blow stable and dispersed airflow into the gap between the top layer of bags and the bags below it, thereby breaking the vacuum adsorption force and electrostatic attraction between the bags, causing the front ends of the top 1-2 bags to be lifted, achieving pre-separation and creating key conditions for subsequent reliable suction. Then, multiple suction nozzles 23 at the lower end of the adsorption plate 21 adsorb the film bags blown by the multiple blowing nozzles 26 through the negative pressure. The adsorption of the suction nozzles 23 provides an excellent peeling force, reliably separating the top layer of bags from the material stack below. Then, the adsorption plate 21 transfers them to the bag release station.

[0024] like Figures 1-4 As shown, the upper surface of the storage platform 13 has multiple arc-shaped grooves 14 that extend from front to back, and the multiple arc-shaped grooves 14 are arranged on the storage platform 13 at equal intervals on the left and right. The multiple arc-shaped grooves 14 make it easy to store the stack of materials, and at the same time make the stack of film bags stable when it is placed on the storage platform 13.

[0025] like Figures 1-4 As shown, the drive assembly includes a lifting drive device 15 mounted on the base plate 11. The upper end of the piston rod of the lifting drive device 15 is fixedly connected to the bottom of the storage platform 13. The lifting drive device 15 drives the piston rod to move the storage platform 13 up and down, so as to lift the storage platform 13 and transport the film bag stack to a height that matches the bag release station.

[0026] like Figures 2-4As shown, the drive assembly also includes a pair of slide rails 16 formed on the inner sidewalls of a pair of side plates 12 and a pair of first sliders 17 slidably connected within the pair of slide rails 16. The ends of the pair of first sliders 17 located outside the slide rails 16 are respectively fixedly connected to the bottom sidewalls of the left and right ends of the arc-shaped groove 14. To ensure linear movement of the storage platform 13 when the lifting drive device 15 drives it up and down, the sliding of the pair of first sliders 17 fixedly connected to the left and right ends of the arc-shaped groove 14 within the slide rails 16 ensures linear movement of the storage platform 13 up and down.

[0027] like Figure 5 and Figure 6 As shown, a vacuum chamber 22 is formed inside the adsorption plate 21, and multiple suction nozzles 23 are connected to the vacuum chamber 22. By providing negative pressure into the vacuum chamber 22, the multiple suction nozzles 23 can generate negative pressure to adsorb and separate the film bag.

[0028] like Figure 5 and Figure 6 As shown, multiple suction nozzles 23 are all designed with a conical structure with a small opening at the top and a large opening at the bottom, which improves the suction capacity of the nozzles 23 for adsorbing the film bags. Simultaneously, the wall panel of the adsorption plate 21 where the suction nozzles 23 are located is made of a flexible material, ensuring that the adsorption of the film bags by the nozzles 23 is a soft contact, thus ensuring that the adsorption of the film bags does not damage their surface while improving the adsorption capacity. A negative pressure pipe 24 is installed on the air inlet of the adsorption plate 21. The negative pressure pipe 24 is connected to a vacuum generator to provide the required negative pressure in the vacuum chamber 22. The vacuum generator is also connected to the suction nozzles 23 via a flexible hose to ensure that the negative pressure can be provided normally when the adsorption plate 21 moves back and forth.

[0029] like Figure 5 and Figure 7 As shown, multiple blowing nozzles 26 are arranged in an upward tilting manner, and the upward tilting angle of the multiple blowing nozzles 26 is set to 45 degrees. When the multiple blowing nozzles 26 spray gas in an upward tilting manner, they can blow a stable and dispersed airflow into the gap between the top layer of bags and the bags below it, thereby breaking the vacuum adsorption force and electrostatic attraction between the bags, causing the front ends of the top 1-2 bags to tilt up, thus achieving pre-separation.

[0030] like Figure 5 and Figure 7 As shown, an air inlet pipe 27 is installed on the air inlet of the blowing pipe 25. The air inlet pipe 27 is connected to the positive pressure fan via a flexible hose to provide blowing gas into the blowing pipe 25. A connecting rod 28 is fixedly connected between the adsorption plate 21 and the blowing pipe 25. The connecting rod 28 fixes the adsorption plate 21 and the blowing pipe 25 together, so that the adsorption plate 21 can drive the blowing pipe 25 to move synchronously. This allows the blowing nozzle 26 to blow the film bag and then adsorb it through the suction nozzle 23, improving the efficiency of film bag separation.

[0031] like Figures 1-3 As shown, a mounting plate 29 is fixedly connected to the rear edge of a pair of side plates 12. A linear motor 210 is mounted on the mounting plate 29, and the mounting plate 29 enables the linear motor 210 to be mounted stably.

[0032] like Figures 1-3 As shown, a second slider 211 is slidably connected to the slide rail of the linear motor 210. A connecting plate 212 is fixedly connected to the second slider 211, and the bottom of the connecting plate 212 is fixedly connected to the upper side wall of the adsorption plate 21. When the linear motor 210 drives the second slider 211 to reciprocate, the second slider 211 can drive the connecting plate 212 to reciprocate, and the reciprocating movement of the connecting plate 212 drives the adsorption plate 21 to reciprocate, thus realizing the reciprocating movement of the adsorption plate 21.

[0033] It should be noted that since this feeding device is used in an automated feeding device, it is equipped with electrical components required for automated feeding in order to realize the automatic lifting and lowering of the storage platform 13, the automatic blowing, adsorption and conveying of the negative pressure adsorption separation component and the positive pressure blowing component during film removal. Since the automated control of the feeding device is a mature existing technology, the required electrical components are not shown.

[0034] In use, a certain number of film bag stacks are stored on the storage platform 13. Then, the storage platform 13 is lifted between a pair of side plates 12 by the lifting drive device 15, thereby conveying the film bag stacks to the loading position by lifting the storage platform 13. When the second slider 211 is driven to reciprocate by the linear motor 210, the second slider 211 can drive the adsorption plate 21 to reciprocate via the connecting plate 212. The adsorption plate 21 can then drive the blowing pipe 25 to reciprocate via the connecting rod 28, so that the blowing pipe 25 moves to the position of the film bag stack near the loading side. Then, multiple blowing nozzles 26 blow stable and dispersed airflow into the gap between the top layer of bags and the bags below them in the stack, thereby breaking the vacuum adsorption force and electrostatic attraction between the bags, causing the front ends of the top 1-2 bags to lift up, achieving pre-separation and creating key conditions for subsequent reliable suction; then, multiple suction nozzles 23 at the lower end of the adsorption plate 21 adsorb the film bags blown up by the multiple blowing nozzles 26 through negative pressure. The adsorption of the suction nozzles 23 provides an excellent peeling force, reliably separating the top layer of bags from the stack below, and then transferring them to the bag release station through the adsorption plate 21.
