Description

Technical Field:

[0002] The present invention relates to a device for inserting cardboard into a cigarette box. Background Art:

[0004] The unpacking robot in the tobacco industry is mainly used for grasping cigarette packs and cigarette boxes. The cigarette pack is integrally packaged by an inner packing box, an outer packing box, upper and lower cardboard (padding boards) or plastic packaging bags. During the production process, the cigarette box is conveyed by a roller conveyor to the working area of the unpacking robot. The manipulator of the unpacking robot clamps the outer packing box of the cigarette pack, and then the upper cardboard is inserted by a nail on the manipulator. Through the rotation of the turnover machine, it is conveyed to the next station to continue grasping the inner packing box and the lower cardboard. However, during the process of the manipulator inserting the upper and lower cardboard, the success rate of cardboard insertion is relatively low, for two reasons: First, the device for the manipulator to insert the cardboard consists of a cardboard detection device and an insertion device. The detection device and the insertion device are separately installed and designed, and the distance is fixed and inconvenient to adjust; Second, due to different grade formulas and different origins of cigarette packs, the sizes of the upper and lower cardboard in the cigarette pack packaging box are also different. Therefore, when the manipulator inserts the cardboard, after the detection device obtains a signal, the nail sometimes does not insert into the cardboard, resulting in the failure of cardboard insertion. Summary of the Invention:

[0006] The present invention provides a device for inserting cardboard into a cigarette box to solve the problems existing in the above-mentioned prior art.

Specific embodiments:

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] As Figure 1 and Figure 2 , a device for inserting and extracting the cardboard of the cigarette box of the present invention includes a mounting base 1, a sliding rod 2, a sliding bearing 3, a detection block 5, a mounting rod 6, a nail 7, a return spring 8, a detection block 9 and a photoelectric displacement sensor 14.

[0025] A cylindrical mounting cavity is provided on the mounting base 1, and the sliding bearing 3 is positioned and installed in the mounting cavity through two snap rings 4. The sliding rod 2 is slidably connected in the mounting cavity of the mounting base 1 through the sliding bearing 3. The detection block 5 and the detection block 9 are both fixed on the sliding rod 2, and the detection block 5 and the detection block 9 are respectively placed on both sides of the sliding rod 2. The detection block 5 is placed outside the mounting cavity, and the mounting position of the detection block 5 on the sliding rod 2 is adjustable.

[0026] The mounting rod 6 is inserted into the sliding rod 2 along the axial direction of the sliding rod 2. The sliding rod 2 can slide on the mounting rod 6. The inner end of the mounting rod 6 is fixedly connected to the inner wall surface of the mounting cavity of the mounting base 1. The outer end of the mounting rod 6 is threadedly connected to the plug pin 7. The plug pin 7 is coaxially arranged with the detection block 5, and the tapered tip on the plug pin 7 is located outside the detection block 5. The return spring 8 is sleeved on the mounting rod 6. The inner end of the return spring 8 abuts against the inner cavity wall of the mounting base, and the outer end abuts against the inner end face of the sliding rod 2.

[0027] An installation frame 13 is fixed on the outer wall of the mounting base 1. A waist-shaped hole is provided on the installation frame 13, and the waist-shaped hole is arranged along the axial direction of the sliding rod 2. The photoelectric displacement sensor 14 is fixed in the waist-shaped hole. The position of the photoelectric displacement sensor 14 on the installation frame 13 can be adjusted, and the photoelectric displacement sensor 1 is used to sense the position change of the detection block 9.

[0028] The detection block 9 is of a T-shaped block structure. The detection block 9 is fixed on the sliding rod 2 by screws or directly by welding. The detection block 9 moves together with the sliding rod 2. A sliding groove 11 is provided on the side wall of the mounting base 1. The sliding groove is arranged along the axial direction of the sliding rod 2. The detection block 9 is slidably connected in the sliding groove 11.

[0029] In the present invention, the mounting rod 6 is threadedly connected to the mounting base 1, which is convenient for disassembly and assembly. The plug pin 7 and the mounting rod 6 are threadedly connected, so that the insertion depth of the plug pin 7 can be adjusted. The specific structure of the mounting rod 6 is: an external thread connecting portion 61 is provided at one end of the mounting rod 6, and a connecting column 62 is provided at the other end. A threaded hole is provided on the connecting column 62. The external thread connecting portion 61 is threadedly connected to the mounting base 1, and the plug pin 7 is threadedly connected to the threaded hole of the connecting column 62. At the same time, a locking nut 72 is threadedly connected to the plug pin 7. After adjusting the plug pin 7 to the required position, the locking nut 72 is tightened to fix the position of the plug pin 7.

[0030] Similarly, the detection block 5 is also threadedly connected to the sliding rod 2. A locking nut (not shown in the figure) is also threadedly connected to the sliding rod 2 and on one side of the detection block 5. After adjusting the detection block 5 to the required position, the locking nut is tightened to fix the position of the detection block.

[0031] A conical head 71 with a tapered tip is provided at the bottom end of the plug pin 7. A barb platform is formed between the conical head 71 and the plug pin 7. After the plug pin 7 is inserted into the cardboard, the cardboard is taken out through the barb platform.

[0032] As Figure 3 , when in use, the picking device of the present invention is fixed on a manipulator. When taking out the cardboard, the manipulator controls the movement of the picking device so that the inserting nail 7 passes through the cardboard 400. As the manipulator continues to move downward, when the detecting block 5 contacts the cardboard, the detecting block 5 pushes the sliding rod 2 upward. The sliding rod 2 moves and drives the detecting block 9 to move together. After the optoelectronic displacement sensor 14 senses a change in the position of the detecting block 9, the manipulator stops moving downward. Then the manipulator drives the device to move upward, and the reset spring 8 resets the detecting block 5, and the cardboard is taken out through the barb platform of the inserting nail 7. The installation positions of the detecting block 5, the inserting nail 7 and the optoelectronic displacement sensor 14 in the present invention can all be adjusted, integrating the detection device with the picking device, effectively improving the success rate of cardboard picking.

[0033] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
