Description

Technical Field

[0001] This invention relates to the field of cigarette packaging equipment technology, and in particular to an automatic cigarette pack picking and feeding device and method. Background Technology

[0002] After the cigarettes pass through the packaging equipment, they are sealed into small boxes. The small boxes are then processed by the cigarette carton machine to form cigarette cartons with transparent packaging. Since the cigarette cartons need to be sealed into boxes by the carton sealing machine, each machine is required to lift the produced cigarette cartons through an S-shaped lifting mechanism and transport them to the carton sealing machine for sealing into boxes.

[0003] During the production process, after the small boxes are packaged into cigarette packs by the packing device, they are conveyed to the S-lift along the cigarette pack conveying direction. If the cigarette packs at the inlet of the cigarette pack conveying device become congested, and subsequent cigarette packs are not stopped being fed into the S-lift device, the cigarette packs will slip into the cigarette storage plate, causing the cigarette pack packaging machine to stop and affecting production efficiency. At the same time, when the S-lift malfunctions, the cigarette packs need to be picked up manually. When the S-lift returns to normal, the picked-up cigarette packs still need to be manually placed back onto the S-lift device. This manual cigarette pack picking device has problems such as low work efficiency and waste of human resources. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides an automatic cigarette pack picking and refilling device and method, which solves the technical defect of the prior art that requires manual picking of cigarette packs.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An automatic cigarette pickup and refill device includes: a power input unit, a cigarette box pickup unit, and a cam trajectory unit; the power input unit provides rotational power to the cigarette box pickup unit, and negative pressure air enters the cigarette box pickup unit to pick up the cigarettes; the cigarette box pickup unit moves up and down along the trajectory of the cam trajectory unit; wherein, the cigarette box pickup unit includes: a rotating disk, a compression spring, a support rod, a rotating smoking disc, a rotating rod, a smoking mouthpiece, a support rod, a roller, and an air sleeve; the rotating disk is connected to the power input unit; one end of each support rod is circumferentially distributed on the upper surface of the rotating disk, and each support rod... The upper part is fitted with the compression spring; the other end of the support rod is evenly distributed around the bottom surface of the rotating smoke tray; multiple rotating rods are evenly distributed around the side surface of the rotating smoke tray, each rotating rod has a mouthpiece below it, and the cavity of the rotating smoke tray is connected to the cavity of the rotating rod; multiple support rods are evenly distributed around the upper surface of the rotating smoke tray, and each support rod has a roller at its end; the air sleeve is set inside the rotating smoke tray and assembled with the power input part through a bearing, the side surface of the air sleeve has an opening, and the width of the air sleeve opening is one-quarter of the circumferential length;

[0007] The automatic cigarette pickup and refill device performs the following refilling method, including:

[0008] When the photoelectric sensor on the S-lifting device detects that the cigarette pack is blocked, the belt on the S-lifting device stops lifting; at the same time, after receiving the signal from the photoelectric sensor, the power input unit drives the cigarette box pickup unit to pick up the cigarette pack and rotate it 90° with the cooperation of the cam track unit. During the rotation, the cigarette pack moves upward to remove it from the cigarette pack conveying channel to avoid colliding with the cigarette pack in front.

[0009] When it is necessary to refill the cigarette packs into the S-lifting device, if the photoelectric sensor does not detect a cigarette pack signal that causes blockage, the power input unit rotates in reverse, causing the entire device to start rotating in reverse, and refilling the cigarette packs adsorbed in the cigarette box pickup unit into the cigarette refilling station at the front end of the S-lifting device.

[0010] Preferably, the cigarette box pickup section is connected to the power input section and the cam trajectory section, respectively.

[0011] Preferably, the power input unit includes: a motor, a pinion gear, and a gear; the motor shaft is fixedly connected to the pinion gear; the pinion gear meshes with the gear.

[0012] Preferably, the rotating smoke tray is coaxially arranged with the air sleeve.

[0013] Preferably, the cam trajectory section includes a cam disk and a cam mounting seat; the cam disk is assembled with the cigarette box pickup section via the cam mounting seat.

[0014] A method for feeding cigarettes based on the above-mentioned automatic cigarette pickup and feeding device, the method specifically includes the following steps:

[0015] When the inlet of the S-lifting device is blocked, the photoelectric sensor installed at the inlet of the S-lifting device detects the blockage and sends a signal to the motor to drive the motor to work.

[0016] The small gear on the motor shaft rotates clockwise, driving the large gear to rotate counterclockwise. The large gear is rigidly connected to the rotating disk, causing the support rod fixed to the rotating disk to rotate, thereby driving the rotating smoke tray installed on the support rod to rotate.

[0017] The rotating smoke tray is made to float up and down by means of a compression spring sleeved on the support rod, which causes the roller at the top of the support rod to contact the cam plate.

[0018] When the air sleeve is connected to the rotating rod cavity, the rotating smoke plate moves downward, and the negative pressure in the air sleeve draws the cigarette through the smoke mouth. Under the action of the cam plate, the rotating smoke plate moves upward and delivers the cigarette to other positions. When the air sleeve is not connected to the rotating rod cavity, the smoke mouth loses negative pressure and the cigarette is released.

[0019] When it is necessary to refill the picked-up cigarette packs into the S-lift inlet, the motor reverses its direction to refill the cigarette packs.

[0020] The beneficial effects of the present invention: The present invention provides an automatic cigarette pickup and refill device and method that realizes the automatic pickup and refill function of cigarettes. When the S-lift inlet is blocked, the cigarettes are automatically picked up. When the blockage of the S-lift inlet is cleared, the cigarettes are refilled into the S-lift inlet. The device has the advantages of being simple and easy to use, fast and efficient, and solves the problems of high labor costs, high workload and low efficiency. Attached Figure Description

[0032] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] like Figures 2-5As shown, this invention provides an automatic cigarette pickup and refill device, which mainly consists of three parts: a power input unit 23, a cigarette box pickup unit 24, and a cam trajectory unit 25. The power input unit 23 provides rotational power to the cigarette box pickup unit 24. Negative pressure air enters the cigarette box pickup unit 24 to pick up the cigarettes 13. The cigarette box pickup unit 24 moves up and down along the trajectory of the cam trajectory unit 25. The power input unit 23 includes a motor 1, a pinion 2, and a gear 3. The cigarette box pickup unit 24 includes a first bearing 4, a rotating disk 5, a compression spring 6, a support rod 7, a second bearing 8, a rotating smoking disk 10, a rotating rod 11, a smoking mouthpiece 12, a support rod 14, a roller support seat 15, and an air sleeve 16. The cam trajectory unit 25 includes a cam disk 9 and a cam mounting seat 19.

[0034] like Figure 3 and Figure 5 As shown, the small gear 2 is fixed to the motor 1, the large gear 3 meshes with the small gear 2, the first bearing 4 is loosely fitted on the lower end of the air sleeve 16, and the large gear 3 is rigidly connected to the rotating disk 5. The first bearing 4 is embedded in the outer circle of the support of the rotating disk 5. The support rod 7 is fixed to the rotating disk 5, the compression spring 6 is loosely fitted on the support rod 7, the lower end of the rotating smoke tray 10 is equipped with a bearing hole, and the second bearing 8 is installed in the bearing hole. In this embodiment, four rotating rods 11 are respectively installed on the rotating smoke tray 10. The rotating rods 11 are hollow rotating rods and communicate with the cavity of the rotating smoke tray 10. Two smoking mouthpieces 12 are installed on the rotating rod 11. Six support rods 14 are fixed to the upper end of the rotating smoking disc 10. Roller support seats 15 are fixed to the upper end of the support rods 14. Rollers 18 are fixed to the roller support seats 15 through roller shafts 17. The circumferential 1 / 4 of the air sleeve 16 is open, corresponding to the two rotating rods 11 of the rotating smoking disc 10. The upper end of the cam disc 9 is fixed to the upper cam mounting seat 19, and the lower end is the cam trajectory.

[0035] A method for automatically picking up and refilling cigarette packs is as follows: Figure 1 As shown, when the photoelectric sensor 20 on the S-lifting device 22 detects a blockage in the cigarette pack, the belt on the S-lifting device 22 stops lifting, and the automatic cigarette pickup and feeding device starts working. After receiving the signal from the photoelectric sensor 20, the small gear 2 on the motor shaft of the motor 1 starts to rotate clockwise, meshing with the large gear 3 to start rotating counterclockwise, which in turn drives the rotating disk 5 to start rotating counterclockwise. The rotating smoking disk 10 is connected to the rotating disk 5 through the support rod 7. Under the action of the compression spring 6, the roller 18 on the rotating smoking disk 10 is in close contact with the cam disk 9. Under the cam trajectory on the cam disk 9, the rotating smoking disk 10 floats up and down, which in turn drives the rotating rod 11 on the rotating smoking disk 10 to float up and down. The smoking mouthpiece 12 on the rotating rod 11 approaches the cigarette pack 13 that needs to be sucked. Figure 3In the process, negative pressure air enters the air sleeve 16 through the inlet at the upper end of the air sleeve 16. Because the air sleeve 16 is coaxially set with the rotating smoke tray 10, the circumferential 1 / 4 opening of the air sleeve 16 is just in contact with the rotating rod 11 of the rotating smoke tray 10 that needs to be smoked. When the smoking mouthpiece 12 is close to the cigarette 13 that needs to be sucked, the rotating rod 11 is connected to the cavity of the air sleeve 16, the air passage of the smoking mouthpiece 12 is opened, and the cigarette 13 is sucked up. Under the action of the rotating smoke tray 10, the cigarette 13 rotates 90°. During the rotation, under the action of the cam plate 9, the cigarette 13 moves upward, ensuring that the cigarette 13 is separated from the cigarette conveying channel and avoids collision with the cigarette in front. After the cigarette 13 has rotated 90°, the air passage of the smoking mouthpiece 12 is closed with the cooperation of the rotating smoke tray 10 and the air sleeve 16, completing the entire process of automatic cigarette picking.

[0036] When it is necessary to refill the cigarette pack 13 into the S-lifting device 22, the photoelectric sensor 20 does not detect the cigarette pack 13 signal, the motor 1 starts to rotate counterclockwise, and the entire device also starts to rotate counterclockwise. The cigarette pack 13 is refilled into the cigarette refilling station at the front end of the S-lifting device 22. The refilling principle is the return process of picking up cigarettes.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
