Technical Field

[0002] A bag making machine is a machine that makes various plastic packaging bags or other material packaging bags.

[0031] This embodiment provides a photoelectric scanning bag making machine, comprising:

[0032] Rack 1;

[0033] The film material conveying mechanism is arranged on the frame 1 and continuously conveys the packaging bag film material;

[0034] The photoelectric scanning assembly at least comprises a photoelectric scanner 20 and a first movable track 21. The photoelectric scanner 20 is mounted on the first movable track 21 and is used to scan the position of the packaging bag film material to provide position information for the subsequent process of the packaging bag. The first movable track 21 is mounted on the frame 1.

[0035] The driving device at least comprises a photoelectric driving mechanism 22 and a first moving track 21 driving mechanism, which are respectively connected to the photoelectric scanner 20 and the first moving track 21 to control the movement of the photoelectric scanner 20 and the overall movement of the photoelectric scanning assembly.

[0036] Reference Figure 1-Figure 2 As shown, this embodiment is described in more detail as follows:

[0037] The frame 1 of this embodiment can adopt the frame 1 of the existing bag making machine as the supporting structure of the entire bag making machine. The film material conveying mechanism is installed on the frame 1, and the film material conveying mechanism can adopt the film material conveying device configured in the existing bag making machine to continuously and uninterruptedly convey the packaging bag film to each preparation station. Since the frame 1 and the film material conveying mechanism can adopt the existing structure, the specific structural settings of the two do not affect the actual implementation of this solution, so the specific structures of the two are not repeated in this embodiment.

[0038] The photoelectric scanner 20 of this embodiment is mainly controlled by a control unit and a photoelectric drive mechanism 22 to control mobile scanning, which is used to scan the current position of the film material and record and feed back to the control unit. More specifically, after the control unit controls the film material conveying mechanism to complete a traction operation through pulse or bus control, the traction data will be fed back to the control unit, and the control unit calculates and controls the photoelectric drive mechanism 22 to drive the photoelectric scanner 20 to complete a scan and record the current scanning position, and repeats the next scanning action. The control unit calculates and controls the traction data of the next film material conveying mechanism by comparing the two adjacent scanning data.

[0039] The photoelectric scanner 20 of this embodiment is installed on the first moving track 21, which is a horizontal track arranged along the width direction of the frame 1. The first moving track 21 has a mounting plate 210, which is arranged at both ends of the frame 1 in the width direction and protrudes from the frame 1. Holes are arranged on the parts of the mounting plates 210 at both ends protruding from the frame 1, and the track screw 211 is fixed on the holes of the mounting plates 210 at both ends to form a state where the track screw 211 is located above the frame 1, so that the photoelectric scanner 20 is always located above the packaging bag film material conveyed on the frame 1; A support 212 that can slide along the track screw 211 is arranged on the track screw 211. The support 212 is an L-shaped structure. The horizontal part 2120 of the L-shaped structure has two holes. The track screw 211 passes through the two holes to realize the installation and mobility of the support 212. The vertical part 2121 of the L-shaped structure of the support 212 is fixed with a photoelectric drive mechanism 22. The photoelectric drive mechanism 22 of this embodiment adopts a servo motor. The photoelectric drive mechanism 22 is connected to the photoelectric scanner 20 and is respectively located on both sides of the L-shaped structure of the support 212. The movement of the photoelectric scanner 20 is driven by the photoelectric drive mechanism 22.

[0040] A second movable track 23 is arranged between the support 212 and the photoelectric scanner 20. The second movable track 23 is installed in the horizontal part 2120 of the L-shaped structure of the support 212. The setting direction thereof is consistent with the length direction of the frame 1. The length of the second movable track is less than the length of the horizontal part 2120 of the L-shaped structure of the support 212, so that the photoelectric drive mechanism drives the photoelectric scanner 20 to scan the position data of the packaging bag film material within the length range of the second movable track.

[0041] To be more specific, a color mark is provided on the film material, and the photoelectric scanner 20 records the color mark signal during the scanning process. The control unit controls the photoelectric drive mechanism 22 to drive the photoelectric scanner 20 to move a certain distance along the second moving track 23. If the photoelectric scanner 20 searches for a valid color mark signal within the photoelectric range of the distance, the current color mark position, i.e., the position of the packaging bag, is fed back to the control unit. If there is no valid color mark signal, the photoelectric drive mechanism 22 drives the photoelectric scanner 20 to expand the corresponding search range, and stops and feeds back the current color mark position data after searching for the color mark signal. The control unit calculates the distance between the two adjacent color mark positions, and thereby calculates the traction distance of the next film material conveying mechanism, and repeats this process to complete each traction and photoelectric positioning.

[0042] In addition, the photoelectric scanning component also has a manual control component 24, which at least has a first lead screw 240 and a first handle 241 fixed at one end of the first lead screw 240, and the other end of the first lead screw 240 is connected to the support 212 of the first movable rail 21 to manually adjust the position of the photoelectric scanner 20 component; the manual control component 24 also has a second lead screw 242 and a second handle fixed at one end of the second lead screw 242, and the other end of the second lead screw 242 is connected to the first movable rail 21 to control the first movable rail 21 to move along the length direction of the frame 1, and a gear part 243 is provided on the second lead screw 242; correspondingly, the frame 1 is provided with a rack part 10 extending along its length direction on one side of the frame body in the width direction, and the gear part 243 is engaged with the rack part 10, so that the manual control component 24 can control the photoelectric scanning component to move along the length direction of the frame 1.

[0043] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention.

[0044] For example, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the utility model. It is not necessary and impossible to list all implementation methods here. Any modification, equivalent substitution and improvement made within the spirit and principle of the utility model shall be included in the scope of protection of the claims of the utility model.
