[0003] However, the existing finger sleeve packaging process mainly relies on manual work, and the efficiency of manual packaging of finger sleeves is low. Each finger sleeve needs to be manually torn off from the finger film, which is time-consuming, labor-intensive, and has limited speed. Secondly, there are health risks in the manual packaging process. Manual operation will inevitably contact the finger sleeve, increasing the risk of contamination. For this reason, special finger sleeve packaging machines have appeared on the market, but some of the existing finger sleeve packaging machines do not have a clamping device to tear the finger sleeve off the finger film during bagging, and they still rely on manual film tearing. There are also some packaging machines with a high degree of automation. Although there is a clamping device, due to the plastic film properties of the finger film, the effect of tearing the finger sleeve off the finger film is not good.

DETAILED DESCRIPTION

[0033] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0034] A gripping device for a finger sleeve packaging machine, such as Figure 1-8 As shown, it includes a film conveyor 1, which is used to carry and forward the finger film. When the finger sleeve bagging process is performed, the finger film needs to be placed at a corresponding position on the film conveyor 1, wherein the film is overlapped and the number needs to be determined according to production requirements. For example, if each packaging bag contains 5 finger sleeves, 5 layers need to be placed. The number of finger sleeves on the finger film is selected according to the mold and the packaging machine.

[0035] Figure 8 A partial view of a material film conveyor 1 is shown, wherein the material film conveyor 1 includes a conveyor body 11, and a plurality of detachable tooling plates 12 are provided on the conveying crawler of the conveyor body 11. Tooling plates 12 of different shapes can be replaced according to production requirements. The upper end surface of the tooling plate 12 is provided with a recess for placing finger films of matching sizes. By setting the recess, a limit can be formed for the finger film during the conveying process to ensure its stability during conveying. A U-shaped notch a121 is provided on the side of the tooling plate 12. The shape of the U-shaped notch a121 is the same as the shape of the tearable part of the finger film, and the number of U-shaped notches a121 is set at least one.

[0036] A pressing mechanism 3 is provided on the top of the film conveyor 1. The function of the pressing mechanism 3 is to press the non-tearable part of the finger film with the film conveyor 1 when tearing the finger film, so as to facilitate the clamping mechanism to clamp the tearable part. The tearable part is the finger sleeve, and the non-tearable part is the part other than the finger sleeve. This part is the waste in the processing process. The tearable part and the non-tearable part are connected in the form of a ridge line. When tearing, the two are broken along the ridge line, so that the finger sleeve is separated, and the bagging operation can be carried out after tearing it off.

[0037] The clamping mechanism is located at one side of the pressing mechanism 3, and the two are opposite in position. When the finger film is pressed, the clamping mechanism tears off the tearable part on the finger film and puts it into a preset packaging bag.

[0038] More specifically, the pressing mechanism 3 includes a support platform 2 and a pressing plate 31, which can be referred to Figure 2The support platform 2 includes fixed bars 21 respectively fixed on both sides of the frame of the film conveyor 1, and the length direction of the fixed bars 21 is parallel to the conveying direction of the film conveyor 1. Each of the two ends of the fixed bar 21 is provided with a vertical slide column 22, and the vertical slide column 22 is vertically arranged to extend the upper end surface of the film conveyor 1. The tops of the four vertical slide columns 22 are jointly fixed with a top plate 23, and the pressure plate 31 is provided with four circular holes, and the four circular holes of the pressure plate are respectively sleeved on the four vertical slide columns 22. The pressure plate 31 is connected to the vertical slide column 22 in a sliding manner, and the pressure plate slides up and down along the vertical slide column 22, that is, it is moved away from and close to the upper end surface of the film conveyor 1. The pressure plate 31 is driven by a first cylinder 32, and the first cylinder 32 is arranged on the top plate 23. The piston rod of the first cylinder 32 passes downward through the top plate 23 and is fixed to the pressure plate 31.

[0039] In addition, it should be noted that a U-shaped notch 33 is provided on the side of the pressing plate 31 facing the clamping mechanism. The shape of the U-shaped notch 33 is the same as the tearable part (finger sleeve) on the finger film. The U-shaped notch 33 is the same as the U-shaped notch a121 in shape and size, and corresponds in position. The number of the U-shaped notches a121 is not less than that of the U-shaped notches a121, and the same number is preferably used. When the finger sleeve is torn off, that is, when the film conveyor 1 is temporarily stopped, the U-shaped notch 33 and the U-shaped notch a121 are in an overlapping state when observed from top to bottom. In order to achieve a better effect of pressing the finger film, a pressure pad 5 is also provided at the bottom of the pressing plate 31. The pressure pad 5 is made of a flexible material and has an anti-slip effect. Its shape can be the same as that of the pressing plate 31.

[0040] When tearing, there is a possibility that the bag may not be broken according to the preset ridge line. At this time, some defective products will be produced during bagging, reducing the qualified rate. For this reason, we further optimize this device and add a bag breaking mechanism 4. Please refer to Figure 2 and Figure 4 The bag breaking mechanism 4 can cut the finger film along the ridge line. Specifically, the bag breaking mechanism 4 includes a second cylinder 41 arranged on the top plate 23 in the same direction as the first cylinder 32. The piston rod of the second cylinder 41 passes downward through the top plate 23 and is connected to a tool holder 42. The tool holder 42 is provided with a U-shaped cutter 43. The outer diameter of the U-shaped cutter 43 is slightly smaller than the inner diameter of the U-shaped notch 33, and it can shuttle up and down along the U-shaped notch 33.

[0041] When the pressing plate 31 presses the finger film, the clamping mechanism clamps the tearable part on the finger film, and then the second cylinder 41 drives the U-shaped cutter 43 downward to cut the finger film along the ridge line to separate it, so as to avoid the situation that the finger film is broken without following the ridge line during tearing, thereby further improving the processing quality of the device.

[0042] like Figure 5-6As shown, the clamping mechanism includes a horizontal support plate 9 and a clamping mechanism body 7, wherein the horizontal support plate 9 is fixedly arranged on the side of the film conveyor 1, and the horizontal support plate 9 corresponds to the position of the pressing mechanism 3 in terms of position relationship, and a linear slide 6 is arranged on the horizontal support plate 9, and the movement direction of the linear slide 6 is perpendicular to the movement direction of the film conveyor; the linear slide 6 can be a synchronous belt type, a screw type, etc., and can perform linear reciprocating motion. Taking the synchronous belt type as an example, refer to Figure 7 The linear slide 6 includes a sliding platform 61, a pulley mechanism 62 and a driving motor 63 arranged on a horizontal support plate 9. The sliding platform 61 is used to install the clamping mechanism body 71. The sliding platform 61 is connected to the pulley mechanism 62 through transmission. The driving motor 63 is connected to the pulley mechanism 62 through transmission and is used to drive the pulley mechanism 62 to operate.

[0043] like Figure 5 As shown, the clamping mechanism body 7 includes a transverse axis 71, a rotary cylinder 72 and a mechanical clamp 73. The transverse axis 71 is rotatably matched with the sliding platform 61 on the linear slide 6. The length direction of the transverse axis 71 is parallel to the moving direction of the film conveyor. The rotary cylinder 72 is fixed to the sliding platform 61 on the linear slide 6. The rotary cylinder 72 is transmission-connected to the transverse axis 71. A plurality of mechanical clamps 73 are arranged on the transverse axis 71 along its length direction. The mechanical clamp 73 includes a clamp cylinder 731 and a clamp finger 732. There are two clamp fingers 732, which are respectively arranged at two movable ends of the clamp cylinder 731. It should be noted that an anti-slip portion is arranged along the length direction of the two clamp fingers 732 on the side close to each other. The anti-slip portion includes a protrusion 732a and a groove 732b. The protrusion 732a is arranged on one of the clamp fingers 732, and the groove 732b is arranged on the other clamp finger 732. Preferably, the protrusion 732a is arranged on a clamp finger 732 at a relatively upper position.

[0044] At least one clamping mechanism body 7 is provided, and two can also be symmetrically provided along the shorter center of the flat support plate 9. If two are provided, the corresponding U-shaped notch 33 on the pressing plate 31, the U-shaped notch a121 on the side of the tooling plate 12 and the U-shaped cutter 43 should be symmetrically provided in two groups.

[0045] In addition, according to the number of finger sleeves on the finger membrane, the corresponding numbers of U-shaped notches 33, U-shaped notches a121 and U-shaped cutters 43 are the same.

[0046] In order to improve the positioning accuracy of the tooling plate 12 and the pressure plate 31, a positioning column 8 is arranged at the bottom of the pressure plate 31, and a positioning hole 122 adapted to the positioning column 8 is correspondingly provided on the tooling plate 12. When the pressure plate 31 performs a clamping action, the positioning column 8 can be inserted and matched with the positioning hole 122 to make the tooling plate 12 stay and be accurate.

[0047] The device also includes a PLC control system, which controls the electrical, pneumatic, and mechanical components of the device, including but not limited to (motors, cylinders, conveyors, etc.). The PLC controls the coordinated operation of various components to achieve precise control.

[0048] The working principle of this utility model:

[0049] First, manually place the finger film on the tooling plate 12 of the film conveyor 1. The upper end surface of the tooling plate 12 is provided with a concave, and its size matches the placed finger film. The PLC controls the film conveyor 1 to start and transport the finger film forward to the position corresponding to the clamping mechanism and the pressing mechanism 3, and stops the forward transmission. This position is the processing station. At this time, the PLC controls the pressing mechanism 3 to operate, and drives the pressing plate 31 to slide along the vertical slide column 22 through the first cylinder 32, so that the pressing plate 31 cooperates with the tooling plate 12 to press the finger film. After pressing, the PLC controls the clamping mechanism to operate, and drives the clamping mechanism body 7 to run toward the lower pressing plate 31 and the tooling plate 12 through the linear slide 6. When it is close to the finger film, The PLC controls the clamping claw cylinder 731 to make the clamping finger 732 clamp the finger film, and then the PLC controls the bag breaking mechanism 4 to operate, and drives the U-shaped cutter 43 to cut downward through the second cylinder 41, so as to cut the finger film clamped by the pressing plate 31, the tooling plate 12, and the clamping finger 732. The cutting position is cut along the preset ridge line, and the finger film is separated after cutting. The tearable part (finger sleeve) is clamped by the clamping finger 732, and the non-tearable part (the rest of the finger sleeve) is clamped by the pressing plate 31 and the tooling plate 12. Then, the PLC controls the material film conveyor 1 to transmit forward, and the non-tearable part falls naturally during the transmission process, and the finger sleeve part is clamped by the clamping finger 732 and sent into the packaging bag. For details, please refer to the attached Fig. 9 , PLC controls the linear slide 6 to drive the clamping mechanism body 7 to run in the opposite direction of the film conveyor 1, that is, to run toward the side of the packaging bag feeding device 10. The packaging bag opens the bag mouth at a position opposite to the clamping mechanism to provide the finger film for feeding. When the clamping mechanism body 7 approaches the packaging bag, the rotating cylinder 72 drives the horizontal axis 71 to rotate 180 degrees, so that the finger sleeve carried by the clamping finger 732 changes from the direction of the unloading film conveyor 1 to the direction of the bag mouth of the packaging bag. As the clamping finger 732 carries the finger sleeve and extends into the packaging bag and releases the finger sleeve, the entire process of tearing off the finger sleeve and bagging is completed.

[0050] The above embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, several modifications, improvements and substitutions can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
