[0031] Refer to Figure 1 、 Figure 2 As shown, an automatic lifting mechanism for a bag storage is provided beside the spare bag storage. The automatic lifting mechanism for the bag storage includes:

[0032] The telescopic mechanism 1 is vertically arranged. The telescopic mechanism 1 includes a body 11 and a telescopic part 12. The bottom end of the telescopic part 12 is installed on the mechanism installation surface 2, and the body 11 can move up and down along the mechanism installation surface 2 with the telescopic movement of the telescopic part 12.

[0033] The lifting frame 3 is connected to the body 11 and can be connected to the spare bag storage.

[0034] The guiding mechanism 4 is installed between the first guiding installation surface 5 and the second guiding installation surface 6 to guide the body 11 during its lifting.

[0035] In one embodiment, the telescopic mechanism 1 adopts an electric cylinder, and the telescopic part 12 is a driving rod of the electric cylinder.

[0036] Compared with traditional mechanical drive systems, electric cylinder drive is more reliable and requires less maintenance. The electric cylinder is driven by a servo motor and cooperates with photoelectric sensors and PLC control systems to achieve precise lifting control, further improving the reliability of the system.

[0037] In one embodiment, a mounting base 21 is provided on the mechanism mounting surface 2 , and the telescopic portion 12 is connected to the mounting base 21 .

[0038] In one embodiment, the guide mechanism 4 includes a linear bearing 41 installed on the side wall of the main body 11, a guide column 42 slidably connected to the linear bearing 41, the first guide mounting surface 5 and the second guide mounting surface 6 are respectively provided with a first guide column base 51 and a second guide column base 61, and the two ends of the guide column 42 are respectively installed on the first guide column base 51 and the second guide column base 61.

[0039] Through the above arrangement, the first guide column base 51 and the second guide column base 61 are mounted on the frame, and the linear bearing 41 is driven by the action of the electric cylinder to move up and down along the guide column 42, thereby driving the lifting frame 3 to move up and down. The structure is simple, the installation is convenient and the reliability is high.

[0040] The guide mechanism 4 provides a stable guiding function when the body 11 is raised or lowered. The sliding connection between the linear bearing 41 and the guide column 42 ensures the stability and accuracy during the lifting process, avoiding errors and failures caused by shaking.

[0041] In one embodiment, the first guide mounting surface 5 is located above the body 11 .

[0042] In one embodiment, the mechanism mounting surface 2 and the second guide mounting surface 6 are located in the same plane, so the second guide column base 61 can be mounted on the mounting base 21 .

[0043] In one embodiment, the lifting frame 3 includes a beam 31 welded to the body 11 and a frame 32 welded to the beam 31 .

[0044] In one embodiment, a photoelectric sensor for detecting the presence of packaging bags is provided on the surface of the lifting frame 3 .

[0045] The telescopic mechanism 1 is designed with an electric cylinder, and its driving rod serves as the telescopic part 12, which simplifies the complexity of the traditional mechanical transmission system, features a compact structure and smooth movement, thus simplifying the overall design. The electric cylinder is driven by a servo motor, and the servo motor and photoelectric sensor can be controlled by a PLC controller to achieve precise operation of the lifting action. At the same time, the adjustment control parameters are set in the touch screen, and it is very convenient to modify and control the parameters such as the speed of lifting and the amount of lifting.

[0046] Working process: Taking a 50 kg aluminum film laminated and hemmed bag (the forming specification of this type of packaging bag is 1000 * 600 mm, and the finished product weight is 210 g) as an example, there are 2 bag libraries, one is a spare bag library and the other is a working bag library (i.e., composed of the automatic lifting mechanism of the bag library). 600 packaging bags can be placed on the lifting frame 3 of the working bag library. At a packaging speed of 1200 bags per hour for the fully automatic packaging machine, the packaging bags in the working bag library can ensure continuous bag supply for half an hour, allowing the operator to replenish the packaging bags in the bag library between 15 - 29 minutes.

[0047] Two proximity switches can be installed on the bag - picking suction cup (controlled by a multi - axis manipulator), with a distance of 10 mm between the proximity switches. When both proximity switches are sensed simultaneously, the lifting mechanism stops operating. After counting 4 times, the lifting mechanism operates and rises 5 mm.

[0048] When there are packaging bags in the working bag library, the photoelectric sensor on the surface of the lifting frame 3 is on; when there are no packaging bags in the working bag library, the photoelectric sensor is off, and the bag - lifting mechanism descends. After descending in place, the spare bag library replenishes the packaging bags to the working bag library, and the lifting mechanism continues the ascending bag - supply operation.

[0049] When the lifting mechanism performs the bag - supply operation, the operator can replenish the packaging bags in the spare bag library.

[0050] Finally, it should be noted that the above - mentioned specific implementation manners are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the examples, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
