Description

Technical Field

[0001] The utility model relates to the technical field of logistics equipment, and particularly relates to a cigarette box unloading device. Background Art

[0002] The unloading device used in cigarette logistics usually has an inclined unloading board, and the cigarette box slides down along the unloading board to unload the cigarette box. However, it is found in actual use that when there is a large height difference during unloading, the higher the inclination of the unloading board, the greater the sliding speed of the cigarette box. When the cigarette box slides to the bottom end, it has a large speed. If not blocked, the cigarette box will slide a long distance on the horizontal plane, which is not convenient for regular stacking; if a stop board is set at the end of the unloading board, the too fast moving speed of the cigarette box will cause it to collide with the stop board, increasing the breakage rate of the cigarettes inside the cigarette box and affecting the quality of the cigarettes.

Detailed implementation manners

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model. It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily.

[0026] Please refer to Figures 1 to 5A cigarette box unloading device includes an unloading channel, a bracket 230 and a buffer platform 20. The bracket 230 is arranged below the unloading channel. The bracket 230 and the buffer platform 20 are respectively located at both ends of the unloading channel. The height of the bracket 230 is greater than the height of the buffer platform 20, so that the unloading channel is in an inclined state under the support of the bracket 230 and the buffer platform 20, and the cigarette box can slide down along the unloading channel to the buffer platform 20 by its own weight to realize unloading; a buffer pad 21 is arranged on the surface of the buffer platform 20, and the buffer pad 21 is movably arranged on the surface of the buffer platform 20 through a buffer spring 211. When the cigarette box moves to contact with the buffer pad 21, the buffer pad 21 moves with the cigarette box, and the buffer spring 211 is compressed to slow down the cigarette box, thereby realizing buffering of the cigarette box and reducing the impact generated when the cigarette box contacts the buffer pad 21.

[0027] See also Figures 3 to 5 The top surface of the buffer platform 20 is the top surface. After the cigarette box sliding down the unloading channel moves onto the buffer platform 20, it moves on the top surface of the buffer platform 20. A buffer groove 201 is provided on the top surface of the buffer platform 20. The buffer groove 201 is a linear groove, and its length direction is consistent with the moving direction of the cigarette box. A slider 212 is fixedly provided at the bottom of the buffer pad 21. The slider 212 is inserted into the buffer groove 201. The cross-sections of the buffer groove 201 and the slider 212 are both inverted T-shaped to prevent the slider 212 from detaching from the buffer groove 201 in the vertical direction, thereby limiting the buffer pad 21, and the buffer pad 21 can only move along the buffer groove 201. The buffer spring 211 is arranged in the buffer groove 201, and the compression direction of the buffer spring 211 is consistent with the length direction of the buffer groove 201. The two ends of the buffer spring 211 are respectively connected to the slider 212 and the inner wall of the buffer groove 201. When the slider 212 moves in the buffer groove 201, the buffer spring 211 is compressed or extended along the direction of the buffer groove 201 to resist the movement of the slider 212, thereby reducing the movement speed of the slider 212 and the buffer pad 21 thereon, thereby playing a buffering role.

[0028] In this embodiment, the two ends of the buffer spring 211 are respectively connected to the front side of the slider 212 (the side for contacting the cigarette box) and the front side of the buffer groove 201. When the cigarette box contacts the buffer pad 21, the buffer pad 21 is forced to move with the cigarette box, and the buffer spring 211 is stretched. Under the elastic force of the buffer spring 211, the buffer spring 211 resists the movement of the buffer pad 21, so that the speed of the buffer pad 21 is reduced, which plays a buffering role. As another embodiment, the two ends of the buffer spring 211 are respectively connected to the rear side of the slider 212 and the rear side of the buffer groove 201. When the buffer pad 21 is forced to move with the cigarette box, the buffer spring 211 is compressed. Under the elastic force of the buffer spring 211, the buffer spring 211 resists the movement of the buffer pad 21, so that the speed of the buffer pad 21 is reduced, which can also play a buffering role.

[0029] The cigarette box is a cuboid or a cube. When the cigarette box moves on the buffer platform 20, the bottom surface of the cigarette box rubs against the surface of the buffer platform 20, and the front end face of the cigarette box contacts the buffer pad 21. Preferably, the end face of the buffer pad 21 for contacting the cigarette box is perpendicular to the surface of the buffer platform 20. In this embodiment, the buffer pad 21 is a flat plate, and the buffer pad 21 is arranged perpendicular to the surface of the buffer platform 20, so that when the cigarette box contacts the buffer pad 21, it is a surface contact between the two, so as to disperse the pressure received by the outer surface of the cigarette box when the cigarette box contacts the buffer pad 21, and the cigarette box can be prevented from tipping over due to uneven contact force.

[0030] In this embodiment, the buffer pad 21 includes a backing plate and a buffer layer provided on one end face of the backing plate. The buffer layer is made of rubber. To increase the strength of the buffer pad 21, the backing plate is arranged on the L-shaped support leg 214. The two right-angled sides of the support leg 214 are respectively fixedly connected to the other end face of the backing plate and the top surface of the slider 212. The support leg 214 is also provided with reinforcing ribs, and the two ends of the reinforcing ribs are respectively connected to the two right-angled sides of the support leg 214 to improve the structural strength of the L-shaped support leg 214. The buffer pad 21 is arranged on the slider 212 through the support leg 214, which can improve the impact resistance of the buffer pad 21 and the connection stability between the buffer pad 21 and the slider 212.

[0031] The buffer platform 20 is also provided with a deceleration block 22. The deceleration block 22 is arranged on the front side of the buffer pad 21. When the cigarette box moves on the buffer platform 20, it first passes through the deceleration block 22 and then contacts the buffer pad 21. By contacting the deceleration block 22, the moving speed of the cigarette box before contacting the buffer pad 21 is reduced, thereby reducing the impact generated by the cigarette box.

[0032] Specifically, an installation groove 202 is provided on the surface of the buffer platform 20. The deceleration block 22 is inserted into the installation groove 202. A deceleration spring 221 is arranged in the installation groove 202. The deceleration spring 221 is arranged vertically, and its two ends are respectively connected to the bottom of the deceleration block 22 and the bottom of the installation groove 202. After installation, the top of the deceleration block 22 is slightly higher than the plane of the buffer platform 20 (not exceeding 10 mm). When the cigarette box passes through the deceleration block 22, the protruding deceleration block 22 contacts the bottom surface of the cigarette box, and the cigarette box rubs against the deceleration block 22 to reduce the speed of the cigarette box; at the same time, when the cigarette box passes through the deceleration block 22, the weight of the cigarette box presses down the deceleration block 22, the deceleration spring 221 is compressed, and then the deceleration spring 221 resets and the deceleration block 22 rises. The deceleration block 22 exerts an upward thrust on the cigarette box, and the friction between the deceleration block 22 and the cigarette box is further increased, improving the deceleration effect of the deceleration block 22 on the cigarette box. A number of deceleration blocks 22 are arranged at intervals along the moving direction of the cigarette box on the surface of the buffer platform 20. The sliding cigarette box moves onto the buffer platform 20, and the cigarette box slides over the deceleration block 22. The deceleration block 22 rubs against the bottom of the cigarette box to reduce the moving speed of the cigarette box, thereby reducing the impact generated after the subsequent movement of the cigarette box collides with the buffer pad 21.

[0033] Further, a slope is provided on one side of the deceleration block 22 facing the unloading channel, and the top of the slope inclines towards the buffer pad 21, so that the cigarette box can be transferred from the plane of the buffer platform 20 to the deceleration block 22 along the slope, avoiding the collision between the bottom edge of the cigarette box and the deceleration block 22, which may cause the cigarette box to be blocked by the deceleration block 22 and unable to move smoothly towards the buffer pad 21.

[0034] In this embodiment, the cross-section of the deceleration block 22 is trapezoidal, and its inclined surface faces the unloading channel. As another implementation manner, the top of the deceleration block 22 is a convex with a semi-circular cross-section, which can also play a guiding role for the cigarette box.

[0035] Please refer to Figure 1 and Figure 2 , the unloading channel includes two guiding grooves 11 that are parallel to each other and spaced apart. The guiding groove 11 is a rectangular parallelepiped frame surrounded by straight plates on all sides. A roller 12 is arranged in the guiding groove 11. Both ends of the roller 12 are rotatably connected to the two side walls of the guiding groove 11. The diameter of the roller 12 is larger than the height of the guiding groove 11. When the roller 12 is installed in the guiding groove 11, the roller 12 protrudes from the top of the guiding groove 11. The cigarette box slides along the guiding groove 11. Specifically, the bottom of the cigarette box contacts the roller 12, and the roller 12 is driven to rotate by the cigarette box, thereby reducing the friction between the cigarette box and the roller 12 and avoiding the wear of the bottom of the cigarette box caused by long-term friction during the sliding process of the cigarette box.

[0036] To adapt to the transportation of cigarette boxes of different sizes, a telescopic rod 13 is also arranged between the two guiding grooves 11. Both ends of the telescopic rod 13 are respectively connected to the two guiding grooves 11. A number of telescopic rods 13 are arranged at intervals along the length direction of the guiding groove 11. The two guiding grooves 11 are connected by the telescopic rod 13. During unloading, the cigarette box slides down along the two guiding grooves 11. The two guiding grooves 11 are respectively located at both ends of the bottom of the cigarette box, and the two guiding grooves 11 jointly support the cigarette box and provide guidance for the sliding of the cigarette box. In this application, the telescopic rod 13 is two hollow tubes sleeved with each other, and fixing parts for fixing the two hollow tubes are arranged on the two hollow tubes. By moving the hollow tubes, the sleeved distance between the two hollow tubes is changed, thereby changing the distance between the two guiding grooves 11. As another implementation manner, the telescopic rod 13 can be a pneumatic telescopic rod 13 or a hydraulic telescopic rod 13.

[0037] Further, fences 14 are arranged on both of the two guiding grooves 11. The fences 14 are fixedly arranged on the sides of the guiding grooves 11. The two sides of the unloading channel are blocked by the fences 14, which can prevent the cigarette box from falling off the guiding groove 11 during the sliding process.

[0038] Correspondingly, to match the width of the unloading channel, in this embodiment, two buffer platforms 20 are arranged at the end of the unloading channel. The buffer platforms 20 are arranged in one-to-one correspondence with the guiding grooves 11 and are connected to the guiding grooves 11. The two buffer platforms 20 are connected by a telescopic rod 13. The telescopic rods 13 between the two guiding grooves 11 and the telescopic rods 13 between the two buffer platforms 20 are adjusted according to the size of the unloading cigarette boxes.

[0039] A bracket 230 is arranged at the bottom of the unloading channel. The inclination angle of the unloading channel can be changed by adjusting the height of the bracket 230 to meet the unloading requirements under different conditions. Specifically, the bracket 230 includes a first rod 31 and a second rod 32. The second rod 32 is inserted into the first rod 31. A plurality of positioning grooves 321 are arranged on the second rod 32 along its length direction. A positioning pin 33 is inserted at one end of the first rod 31 connected to the second rod 32. By moving the second rod 32, the overlapping length of the first rod 31 and the second rod 32 is changed, thereby changing the overall length of the bracket 230. When the second rod 32 is moved to a suitable position, the positioning groove 321 and the positioning pin 33 are aligned, and the positioning pin 33 is inserted into the positioning groove 321. The positioning pin 33 fixes the first rod 31 and the second rod 32. Both the first rod 31 and the second rod 32 are vertically arranged. The end of the first rod 31 is rotatably connected to the end of the guiding groove 11 to adapt to the change in the angle between the rod and the guiding groove 11 at different heights of the bracket 230. Correspondingly, the other end of the guiding groove 11 is rotatably connected to the buffer platform 20 to enable the change in the angle between the buffer platform 20 and the guiding groove 11 at different inclination angles of the guiding groove 11.

[0040] Preferably, moving wheels 40 are arranged at the bottom of the bracket 230, that is, at the bottom of the second rod 32, and moving wheels 40 are also arranged at the bottom of the buffer platform 20 to facilitate the transfer of the device or the adjustment of the position of the device.
