Description

Technical Field

[0001] The technical solution relates to the technical field of packaging equipment, and in particular to a fully automatic station-adjusting bag-making machine. Background Art

[0002] Bag making machines are machines that make various plastic packaging bags or other material packaging bags. In the process of preparing packaging bags, they will go through processes such as conveying and unwinding, correcting deviation, hot sealing, and cutting. In this preparation process, the packaging bags and their film materials will undergo different degrees of stretching and curling. When undergoing process flows such as hot sealing and cutting into bags that require position determination, it is inevitable that the hot sealing and cutting positions will be inaccurate, resulting in waste of resources and poor yield of packaging bags. This requires the use of position control devices to position the packaging bags in the process. In addition, based on the inaccurate position of the packaging bag, the corresponding position adjustment of each functional mechanism is also required. The current position adjustment of each functional mechanism also requires manual participation. The adjustment process is cumbersome and the accuracy is not high, which increases the difficulty of the operation. Utility Model Content

The frame 1 can adopt the existing frame of the bag making machine. Similarly, the driven traction mechanism in the two traction control groups of the active traction mechanism 3 involved in the present embodiment can adopt the traction structure of the existing bag making machine. Therefore, the specific structure of the frame and each traction mechanism can refer to the existing technology, and no excessive explanation is given in the present embodiment.

[0047] The following is a more detailed technical description:

[0048] A first movable track is arranged on the frame 1, and the first photoelectric scanning element 2 is arranged on the first movable track. Through the first movable track, the first photoelectric scanning element can move back and forth along the length direction of the frame; in actual operation, the first movable track can adopt a slide rail, a lead screw, a gear rack and other structures. The purpose of setting the first movable track is to realize the mobility of the first photoelectric scanning element 2. Therefore, structures such as the above are all within the protection scope of this technical solution.

[0049] The first photoelectric scanning element 2 can be a photoelectric sensor or a photoelectric scanner, etc., and its purpose is to Figure 2 The color mark 70 on the packaging bag film 7 shown is scanned in real time to determine the current position of the packaging bag film 7, and can be transmitted to the controller in real time through the control program to calculate the data in order to control the operation speed of the subsequent process.

[0050] The active traction mechanism 3 is arranged adjacent to the first photoelectric scanning element 2, and the active traction mechanism 3 and the photoelectric scanning element 2 are connected by signals. When the photoelectric scanning element 2 detects the color mark 70 of the packaging bag film 7, the detection information is transmitted to the active traction mechanism 3, and the active traction mechanism 3 stops working and starts again after completing the operation of the current functional mechanism, that is, the active traction mechanism 3 follows the first photoelectric scanning element 2 to start and stop.

[0051] A first traction control group 4 and a second traction control group 5 are respectively provided on both sides of the first photoelectric scanning element 2 and the active traction mechanism, wherein the first traction control group 4 has at least a first driven traction mechanism 40 and a first driving mechanism 41, the first driven traction mechanism 40 is driven and controlled by the active traction mechanism 3, the first driving mechanism 41 is arranged on the first functional mechanism, and realizes signal connection with the first photoelectric scanning element 2, drives the first functional mechanism between the active traction mechanism 3 and the first driven traction mechanism 40 to complete the corresponding process, in this embodiment, the first functional mechanism between the active traction mechanism 3 and the first driven traction mechanism 40 is a transverse sealing and ironing mechanism 42, in actual use, a third driven traction mechanism can also be provided upstream of the first driven traction mechanism 40, and a longitudinal sealing and ironing mechanism and other functional mechanisms can be provided between the first driven traction mechanism 40 and the third driven traction mechanism, that is, when implementing this scheme, it is not limited to providing only one traction control group on the first photoelectric scanning element 2.

[0052] In connection therewith, the second traction control group 5 at least comprises a second driven traction mechanism 50, a second photoelectric scanning element 55 and a second driving mechanism 51. The second driven traction mechanism 50 is also driven and controlled by the active traction mechanism 3. In this embodiment, the second photoelectric scanning element 55 is fixedly arranged on the frame 1, and scans the position of the color mark 70 on the packaging bag film material 7 currently passing through the second photoelectric scanning element 55 and feeds back to the controller for data processing. In other embodiments, the second photoelectric scanning element 55 can be the same as the first photoelectric scanning element 2, and a movable guide rail can be arranged on the frame 1. The second photoelectric scanning element 55 is installed on the movable guide rail to realize real-time scanning; the second photoelectric scanning element 55 is connected with the second driven traction mechanism 50 by signal to control the start and stop of the second driven traction mechanism 50, that is, when the second photoelectric scanning element 55 scans the position of the color mark 70 on the packaging bag film 7, the signal is transmitted to the second driven traction mechanism 50, and the second driven traction mechanism 50 stops working and starts again after completing the current operation process; the second driving mechanism 51 is connected with the first photoelectric scanning element 2 by signal to drive the second functional mechanism between the active traction mechanism 3 and the second driven traction mechanism 50 to complete the corresponding process.

[0053] The second functional mechanism between the active traction mechanism 3 and the second driven traction mechanism 50 includes at least a transverse sealing cooling mechanism 52 and a punching mechanism 53. After the second functional mechanism completes the corresponding operation process, the packaging bag film 7 enters the cutting mechanism 54 to complete the cutting operation. The cutting mechanism 54 can be arranged between the active traction mechanism 3 and the second driven traction mechanism 50, or it can be extended to the functional mechanism of the fourth traction control group to perform photoelectric scanning and positioning separately.

[0054] It should be noted that a second movable track is provided on the frame 1, and the first functional mechanism controlled by the first driving mechanism 41 and the second functional mechanism controlled by the second driving mechanism 51 are provided on the second movable track. Through the second movable track, the first functional mechanism and the second functional mechanism can move back and forth along the length direction of the frame 1. Similar to the first movable track, the second movable track can also be provided with structures such as slide rails, lead screws, gear racks, etc.

[0055] A third movable rail 61 is provided on the frame 1, and the detection mechanism 6 is installed on the third movable rail 61. Through the third movable rail 61, the detection mechanism 6 can move back and forth along the length direction of the frame 1; correspondingly, the first photoelectric scanning element 2, the first driving mechanism 41 of the first traction control group 4 and the second driving mechanism 51 of the second traction control group 5 are all provided with a detection piece 60, and the detection piece 60 is connected with the detection mechanism 6 to realize signal connection, so that the detection mechanism 6 can obtain the real-time position information of the first photoelectric scanning element 2 and the first functional mechanism controlled by the first driving mechanism 41 and the second functional mechanism controlled by the second driving mechanism 51 in real time.

[0056] The active traction mechanism, the first photoelectric scanning mechanism, the first traction control group, the second traction control group, the functional mechanism and the detection mechanism are all driven by servo motors.

[0057] In this embodiment, the controller adopts a bus-type motion controller, and controls the servo motors connected to the bus through communication instructions to complete a series of control functions of the bag making machine such as traction, ironing, and cutting. The switch signals of the first photoelectric scanning element 2 and the second photoelectric scanning element 55 in this embodiment are connected to the input end of the controller; when the first photoelectric scanning element 2 and the second photoelectric scanning element 55 detect the color mark 70 mark of the packaging bag film 7, the controller receives the switching amount signal of the first photoelectric scanning element 2 and the second photoelectric scanning element 55. When the switching amount signal of the positioning photoelectric is valid, the servo motor is pulled through a certain length of the packaging bag film 7, and the controller records the current position and speed information of the servo motor, and then controls the servo motor to run a fixed length, thereby making the overshoot distance of the servo motor constant to ensure the consistency of the positioning of the color mark 70.

[0058] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
