[0020] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0021] like Figure 1 、 Figure 2 As shown, this embodiment discloses a carton palletizing device, comprising a base 1, on which a tray 2 for carton palletizing is provided. Figure 4 Specifically, the base 1 houses a motor (not shown). The motor's output is connected to a connector 6, which has a square hole inside. A square rod 7 is located at the bottom of the tray 2, which fits into the square hole. Through the interaction between the square hole and the rod 7, the motor, via the connector 6, drives the tray 2 to rotate on the surface of the base 1. Furthermore, the tray 2 and base 1 are designed to be removable, facilitating loading and unloading of cartons.

[0022] A film wrapping device is provided on one side of the pallet 2. The device consists of a stand 3 and a liftable film wrapping assembly mounted on the stand 3. The film wrapping assembly includes a column 4 that is linked to the stand 3 for lifting and lowering and is slidably connected, and a film tube 5 mounted on the column 4. The film tube 5 can be easily assembled and disassembled from the column 4. Specifically, a chassis for supporting the film tube 5 is provided at the bottom of the column 4, and the chassis is connected to the stand 4 by a thread. In this embodiment, the chassis is circular in design, and its diameter is significantly smaller than that of the film tube 5 to ensure that the chassis does not come into contact with the carton. The assembly and disassembly of the chassis facilitates the assembly and replacement of the film tube 5. An elastic device is provided on the stand 3 for pushing the column 4 and the film tube 5 closer to the pallet 2. The elastic force of the elastic device ensures that the film tube 5 can fit tightly against the carton, thereby achieving a tighter wrapping. A slide 8 is provided on the stand 3 for lifting and sliding. The lifting and lowering of the slide 8 can be achieved by a driving device such as a rodless cylinder. The carriage 8 is equipped with a slideway 9 extending through it, through which the top of the column 4 slides. A stopper 10 is installed at the top of the column 4 to prevent it from escaping from the slideway 9. The carriage 8 can move the column 4 upward and downward. The main function of the upward movement of the column 4 is to elevate the film drum 5, allowing the film to be gradually wound upward, thus wrapping all the cartons in the stack.

[0023] Given the length of the column 4, to prevent it from swaying during operation, a retaining slot 11 is designed at the top of the frame 3 for the column 4 to pass through. The column 4 can be raised, lowered, and slid in the retaining slot 11. The function of the retaining slot 11 is to enhance the stability of the column 4 and prevent it from swaying.

[0024] The stand 3 is provided with a slide groove 12 on one side close to the column 4. The slide groove 12 is vertically arranged. The elastic device is slidably arranged in the slide groove 12. During the lifting and lowering process of the film tube 5, the elastic device will also be lifted and lowered in the slide groove 12, so that the elastic device can continuously provide elastic force, so that during the film winding process, the film can always fit the carton.

[0025] like Figure 3As shown, the elastic device includes a connecting block 13 fixedly connected to the column 4, a slide 14 arranged in the chute 12, and an elastic member 15 located between the slide 14 and the connecting block 13. The slide 14 slides and fits on the inner wall of the chute 12, and the elastic member 15 can be a spring. One end of the elastic member 15 is connected to the connecting block 13, and the other end is connected to the slide 14. One end of the connecting block 13 extends into the chute 12 and is connected to the elastic member 15, and can be lifted and lowered longitudinally and slid laterally in the chute 12. Under the elastic force of the spring, the connecting block 13 can move laterally in the chute 12, so that the elastic force of the spring acts on the column 4 through the connecting block 13, driving the film tube 5 to fit the carton. To prevent the connecting block 13 from detaching from the chute 12, limit bars 16 are provided on both sides of the limit slot 11. There are two limit bars 16, located on both sides of the chute 12.

[0026] The stop bar 16 is equipped with a locking device for locking the connecting block 13. The locking device includes a locking screw 17 threadedly connected to the stop bar 16. Two locking screws 17 are provided, located on both stop bars 16. The locking screws 17 are primarily used to overcome the elastic force of the spring and press the connecting block 13 against the chute 12, ensuring a tight fit between the film tube 5 and the carton, facilitating carton loading and unloading operations.

[0027] Working principle: Use the fastening bolts to tightly fit and fix the connecting block 13 in the slide 12, ensuring that the film tube 5 maintains a certain distance from the pallet 2. Then, the robotic arm stacks the cartons filled with items on the pallet 2. After the stacking is completed, rotate and loosen the fastening bolts. With the help of the elastic force of the spring, the connecting block 13 guides the column 4 to move along the slide 9 and the limit groove 11, so that the film fits tightly to the surface of the carton. Then, tear off the film from the film tube 5 and attach it to the carton. After starting the motor, the motor drives the pallet 2 to rotate, which in turn drives the carton to rotate. During the rotation of the carton, the film is wrapped around the carton. During the wrapping process of the film, since the carton is square, the slide 9 can provide space for the column 4 to move back and forth laterally during the rotation process, and the slide 12 can provide space for the connecting block 13 to overcome the elastic force of the spring to move back and forth laterally. The continuous elastic force of the spring acts on the film tube 5 to ensure that it fits tightly to the carton. Simultaneously, the rodless cylinder slowly raises the carriage 8, which in turn drives the column 4 and film drum 5 upward until the film completely wraps around the carton. As the column 4 rises, the connecting block 13, slide plate 14, and spring also rise and slide within the chute 12. It should be noted that the spring force is insufficient to interfere with the rise of the column 4. In this embodiment, the column 4 and film drum 5 rise slowly to ensure film wrapping. This achieves automatic film wrapping and improves operational efficiency.

[0028] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
