Description

Technical Field

[0001] The utility model relates to the technical field of cigarette box handling, in particular to a cigarette box clamping vehicle. Background Art

[0002] The raw material storage warehouse of a cigarette factory is mainly used for storing tobacco leaves. The tobacco leaves are stored in cartons, and the cartons are directly stacked on the ground, with a maximum stacking of 4 layers. A clamping vehicle is used as the handling tool. The cigarette box stack in the raw material warehouse is not a fixed shelf. When the 4-layer cigarette box stack changes with the handling of cigarette boxes, the changes in the stack are diverse. It is necessary to construct a two-dimensional map suitable for the raw material warehouse of the cigarette factory. The radar emits laser light and uses laser scanning of fixed buildings to construct the two-dimensional map of the building. There are multiple floor warehouses in the raw material warehouse of the cigarette factory, and the operation content of each warehouse on each floor is almost the same. The operation time of several floors of warehouses can be reasonably planned, and the handling operation time can be staggered. In order to improve the efficiency of handling cigarette boxes, the clamping AGVs on other floors can be called. For example, the clamping AGV on the first floor can be scheduled to be used on the second floor, and the clamping vehicle can be transported to the target floor by the elevator. However, in order to expand the scanning range of the radar, the existing clamping vehicle generally fixes the radar on the top of the vehicle: First, the scanning range of the radar will be a fixed range, and the scanning range of the radar cannot be adjusted; Second, when the radar is fixed on the roof of the vehicle, the height of the radar will be higher than the height of the elevator, which makes the clamping vehicle unable to smoothly enter the elevator, so the clamping vehicle cannot quickly run to the target floor, reducing the use efficiency of the clamping vehicle.

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. Apparently, 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 shall fall within the protection scope of the present utility model. It should be noted that, without conflict, the embodiments in this application and the features in the embodiments may be combined with each other arbitrarily.

[0026] Please refer to Figures 1 to 7 . A cigarette box clamping vehicle according to an embodiment of the present utility model includes a chassis 2, a vehicle body 1 vertically disposed on the chassis 2, a mounting frame 6, a radar 5 disposed on the mounting frame 6, a gantry 3 disposed on the chassis 2, a fixture 4 disposed on the gantry 3 for clamping a cigarette box 8, and a lifting member 7 having two ends respectively connected to the vehicle body 1 and the mounting frame 6 for lifting the mounting frame 6. The lifting member 7 may include a motor 71 disposed on the vehicle body 1, a lead screw 73 rotatably connected to the bottom of the vehicle body 1, an adjusting nut 74 disposed on the lead screw 73, a first connection structure 76 having two ends respectively connected to the mounting frame 6 and the adjusting nut 74, and a first transmission structure 72 having two ends respectively connected to the lead screw 73 and the output shaft of the motor 71.

[0027] Here, the height of the mounting frame 6 is adjusted by the lifting member 7, thereby adjusting the height of the radar 5. Since the radar 5 is installed at the top of the mounting frame 6, that is, the radar 5 is at the highest position of the clamping vehicle, the overall height of the clamping vehicle can be adjusted, which can not only adjust the scanning range of the radar 5, but also facilitate the clamping vehicle to enter different height-limited positions. For example, it is convenient for the clamping vehicle to enter an elevator. When the clamping vehicle runs near the elevator, the radar 5 is lowered by the lifting member 7 to a height that meets the requirement for entering the elevator.

[0028] The lifting member 7 may further include a first guiding structure 75 for guiding the adjusting nut 74 when the adjusting nut 74 moves up and down along the lead screw 73.

[0029] The first guiding structure 75 may include a first guide rail 751 connected to the vehicle body 1, a first slider 752 slidably connected to the first guide rail 751, and a first connecting rod 753 having two ends respectively connected to the side surface of the first slider 752 and the adjusting nut 74.

[0030] Specifically, the axis of the lead screw 73 is parallel to the center line of the vehicle body 1, and the axis of the first guide rail 751 may be parallel to the axis of the lead screw 73.

[0031] The first connection structure 76 may include a first support rod 761. Two ends of the first support rod 761 are respectively connected to the mounting bracket 6 and the top end of the adjusting nut 74. It further includes a second guiding structure 77 for guiding the second connecting rod 773 when the first support rod 761 moves up and down.

[0032] The first connection structure 76 may further include a first guiding block 762 provided on the first support rod 761. The second guiding structure 77 includes a second guide rail 771 connected to the vehicle body 1, a second sliding block 772 slidably connected to the second guide rail 771, and a second connecting rod 773 with two ends respectively connected to the first guiding block 762 and the second sliding block 772.

[0033] Specifically, the axis of the first support rod 761 may be parallel to the axis of the lead screw 73, and the axis of the second guide rail may be parallel to the axis of the lead screw 73. The second guide rail 771 is fixed to the vehicle body 1. The first support rod 761 and the lead screw 73 are both parallel to the vehicle body 1. Compared with the lead screw 73, the first support rod 761 is arranged farther away from the vehicle body 1, that is, the distance between the lead screw 73 and the vehicle body 1 is less than the distance between the first support rod 761 and the vehicle body 1. The first support rod 761 is parallel to the lead screw 73, and the cross-sectional area of the first support rod 761 is larger than the cross-sectional area of the lead screw 73. A first connection through hole for the lead screw 73 to pass through may be provided through the first guiding block 762.

[0034] As a cigarette box clamping vehicle in this embodiment, it may further include a controller for controlling the motor 71. The second guiding structure 77 further includes an upper travel switch 784 provided on the upper part of the second guide rail 771, a lower travel switch 781 provided on the lower part of the second guide rail 771, a first triggering part 783 provided on the top of the second sliding block 772, and a second triggering part 782 provided on the bottom of the second sliding block 772. The controller is used to control the motor 71 to stop when the first triggering part 783 abuts against the upper travel switch 784 or the second triggering part 782 abuts against the lower travel switch 781.

[0035] Specifically, both the first trigger part 783 and the second trigger part 782 can adopt the trigger parts disclosed in CN221196864U, a display lifting column, and the upper travel switch 784 and the lower travel switch 781 can both adopt the travel switches disclosed in CN221196864U, a display lifting column. The first trigger part 783 and the second trigger part 782 can also adopt the trigger parts disclosed in CN221459048U, an automatic flipping device for part production, and the upper travel switch 784 and the lower travel switch 781 can also adopt the travel switches disclosed in CN221459048U, an automatic flipping device for part production. When the first trigger part 783 abuts against the upper travel switch 784, the upper travel switch 784 sends a trigger signal to the controller. At this time, the installation rack 6 has reached the highest point of its upward movement. When the second trigger part 782 abuts against the lower travel switch 781, the lower travel switch 781 sends a trigger signal to the controller. At this time, the installation rack 6 has reached the lowest point of its downward movement. When the controller receives the trigger signal, it controls the motor 71 to stop, thereby protecting the installation rack 6 and the second slider 772.

[0036] The lifting member 7 may further include a support seat fixed to the vehicle body 1 and a first mounting through hole provided on the support seat. The middle part of the lead screw 73 is rotatably connected to the first mounting through hole, and the bottom end passes through the first mounting through hole and extends below the support seat. The first transmission structure 72 includes a first rotating wheel 721 provided on the output shaft of the motor 71, a second rotating wheel 722 provided on the part of the lead screw 73 extending below the support seat, and a first belt 723 sleeved on the first rotating wheel 721 and the second rotating wheel 722 at both ends.

[0037] Specifically, a bearing may be provided in the middle part of the lead screw 73. The lead screw 73 is sleeved on the inner ring of the bearing, and the outer ring of the bearing is fixed at the first mounting through hole of the support seat. When the motor 71 rotates, the output shaft of the motor 71 drives the first rotating wheel 721, the first rotating wheel 721 drives the first belt 723, the first belt 723 drives the second rotating wheel 722, and the second rotating wheel 722 drives the lead screw 73.

[0038] The lifting member 7 may further include a scale 79 for positioning the height of the adjusting nut 74 when the adjusting nut 74 moves up and down.

[0039] Specifically, the current height of the nut and the target height after moving up and down can be known through the scale 79. The distance for adjusting the movement of the adjusting nut 74 can be obtained based on the target height and the current height. When the radar 5 is located at the top of the clamping truck, the maximum height of the radar 5 can be obtained through a tape measure. At this time, the first height corresponding to the adjusting nut 74 can be obtained through the scale 79. When the clamping truck needs to enter the elevator, the radar 5 is higher than the second height of the elevator entrance. The distance that the radar 5 descends can be obtained based on the maximum height and the second height. The distance that the radar 5 descends is the distance that the adjusting nut 74 descends. Thus, the height of the adjusting nut 74 after descending can be obtained based on the first height and the descending distance. The position where the adjusting nut 74 descends can be positioned according to the scale 79, which is convenient for accurately adjusting the position of the adjusting nut 74 and realizing the accurate adjustment of the position of the radar 5.

[0040] The first guide rail 751 may be provided with a first insertion slot, and the scale 79 is inserted into the first insertion slot. The axis of the scale 79 is parallel to the axis of the lead screw 73.

[0041] Specifically, a first insertion slot is recessed on the side surface of the first guide rail 751 away from the vehicle body 1, and the scale 79 is inserted into the first insertion slot, so as to facilitate the installation of the scale 79 on the first guide rail 751.

[0042] As a kind of cigarette box clamping truck in this embodiment, it may further include a first screw rod connected to the top end of the mounting bracket 6, a screw tube with its inner side wall screwed to the first screw rod, and a first connecting portion provided on the outer side wall of the screw tube. The radar 5 is detachably connected to the first connecting portion.

[0043] Specifically, the screw tube is screwed to the first screw rod. When the screw tube rotates, it drives the first connecting portion to rotate, so as to realize the adjustment of the angle of the first connecting portion, and further realize the adjustment of the angle of the radar 5. The radar 5 can scan different areas. At the same time, by rotating the screw tube, the height of the screw tube corresponding to the first screw rod can be finely adjusted, so as to realize the fine adjustment of the height of the radar 5. At the same time, the screw tube is screwed to the first screw rod and the radar 5 is detachably connected to the first connecting portion, which is convenient for replacing the radar 5.
