Description

Technical Field

[0001] This invention belongs to the technical field of tobacco production, and specifically relates to a tobacco box transport device in the process of packing and transporting tobacco materials. Background Technology

[0002] In highly automated tobacco processing production lines, the combined application of box-type tobacco storage technology and logistics systems significantly improves production efficiency. Currently, mature tobacco storage systems typically use a certain number of tobacco boxes as transport units, working in conjunction with railcar systems, high-bay warehouse systems, and roller and chain conveyor equipment to complete the flow operations. When any link in the box-type tobacco storage system malfunctions or a single tobacco box needs to be removed, a device is required to move tobacco boxes in and out, and to load and unload tobacco. In actual production, manual adjustments are still necessary to remove tobacco from any node in the circulating chain for adjustments. Due to the large number of tobacco boxes, long circulating chain travel, narrow passages in some workshops, high manpower requirements, and a limited number of skilled forklift operators, in addition to maintaining normal production with existing equipment, a device is needed that allows the tobacco boxes to move freely and has a tilting function to facilitate tobacco loading and unloading. Summary of the Invention

[0003] To address the technical problems of difficulty in transferring tobacco boxes between different conveying equipment in the workshop and the inconvenience of loading or removing tobacco shreds from the tobacco boxes, this invention provides a tobacco box transport device that can pick up and put down tobacco boxes at different heights, move the tobacco boxes freely in confined environments, and shovel and dump materials through vehicle movement and the tilting of the clamping cradle.

[0004] The technical solution adopted in this invention is:

[0005] A cigarette box transport device, characterized in that it comprises:

[0006] The transport vehicle body has two pairs of casters installed at the bottom. One pair of casters is installed at the front of the transport vehicle body to enable the transport vehicle body to turn, and the front section can extend into the bottom of the smoke box; the other pair of casters is installed at the rear of the transport vehicle body to enable the transport vehicle body to turn and move.

[0007] The rocker arms are located on both sides of the transport vehicle body. One end of each rocker arm is movably connected to an electric cylinder via a ball joint. The extension and retraction of the electric cylinder causes the rocker arm to swing up and down. The electric cylinder is fixed to the transport vehicle body via the ball joint. The other end of the rocker arm is connected to a clamping arm. The rotational power of the clamping arm is provided by a servo motor. The clamping parts of the two clamping arms are positioned opposite each other to form a clamping space for clamping the cigarette box. When the clamping arms clamp, the change in the rocker arm angle is offset by a horizontal rotary joint, maintaining the alignment of the horizontal rotation angles of the two rocker arms. The spatial displacement generated at the end of the rocker arm is offset by the rotation of the ball joint and the extension and retraction of the electric cylinder.

[0008] A pneumatic linkage mechanism includes a hinge fixing block, a hinge rotating block, a connecting rod, a cylinder connecting rod, and a cylinder. The cylinder body and the cylinder rod are respectively fixedly connected to two cylinder connecting rods. The left and right ends of the cylinder connecting rods are respectively fixedly connected to the connecting rods by pins. The outer end of the connecting rod is connected to the hinge fixing block by a pin. The hinge rotating block has a through shaft at its center, which connects the upper and lower hinge fixing blocks together and is fixedly connected to the end face of the vehicle clamping arm. When a clamping command is executed, the cylinder expands, and the distance between the two cylinder connecting rods connected to the cylinder increases. Under this action, the two sets of hinge fixing blocks and hinge rotating blocks distributed on the left and right sides move closer together under the drive of the connecting rod, thereby driving the vehicle clamping arm fixed to the hinge rotating block to complete the clamping action; conversely, the vehicle clamping arm opens.

[0009] Furthermore, two pillars are provided in the middle of the transport vehicle body, and the top of each pillar is equipped with the horizontal steering joint, the end of which is connected to a rocker arm that can swing up and down.

[0010] Furthermore, both the other end of the rocker arm and the end of the horizontal rotary switch are provided with sprockets, one of which is connected to the output shaft of a servo motor, and the two sprockets are connected by a chain to counteract the horizontal displacement changes caused by the rocker arm angle.

[0011] Furthermore, the inner side of the clamping arm is provided with a groove and a limiting block, which, together with the outer contour of the cigarette box, achieves all-round fixation.

[0012] Furthermore, motor-driven steering wheels are installed on the omnidirectional wheels located at the rear, which provide power for the movement of the transport vehicle body.

[0013] Compared with the prior art, the beneficial effects of the present invention are reflected in:

[0014] 1. The transport device of the present invention can not only pick up and put down cigarette boxes at different heights, but also carry cigarette boxes to move freely in confined spaces, and can also shovel and dump materials through vehicle movement and clamp arm flipping.

[0015] 2. The present invention has a compact overall structure, a reasonable layout, and a novel design. Attached Figure Description

[0024] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0027] refer to Figures 1 to 8 The present invention provides a cigarette box transport device, comprising:

[0028] The transport vehicle body 1 has two pairs of casters installed below it. One pair of casters 11 is installed at the front of the transport vehicle body to enable the transport vehicle body to turn. The front section can extend into the bottom of the cigarette box. The other pair of casters 9 is installed at the rear of the transport vehicle body to enable the transport vehicle body to turn and move.

[0029] One rocker arm 4 is installed on each side of the transport vehicle body 1. One end of the rocker arm 4 is movably connected to an electric cylinder 5 through a ball joint. The extension and retraction of the electric cylinder 5 causes the rocker arm 4 to swing up and down. The electric cylinder 5 is fixed to the transport vehicle body 1 through the ball joint. The other end of the rocker arm 4 is connected to a clamping arm 12. The rotational power of the clamping arm 12 is provided by a servo motor 6. The clamping parts of the two clamping arms 12 are arranged opposite to each other to form a clamping space for clamping the cigarette box. When the clamping arm 12 clamps, the change in the included angle of the rocker arm 4 is canceled by the horizontal rotation joint 3, and the alignment of the horizontal rotation angle of the two rocker arms 4 is maintained. The spatial displacement generated at the end of the rocker arm 4 is canceled by the rotation of the ball joint and the extension and retraction of the electric cylinder.

[0030] The pneumatic linkage mechanism 10 includes a hinge fixing block 101, a hinge rotating block 102, a connecting rod 103, a cylinder connecting rod 104, and a cylinder 105. The cylinder body and the rod of the cylinder 105 are respectively fixedly connected to two cylinder connecting rods 104. The left and right ends of the cylinder connecting rod 104 are respectively fixedly connected to the connecting rod 103 by pins. The outer end of the connecting rod 103 is connected to the hinge fixing block 101 by a pin. The hinge rotating block 102 has a through shaft at its center, which connects the upper and lower hinge fixing blocks 101 together and is fixedly connected to the end face of the vehicle clamping arm 12. When a clamping command is executed, the cylinder expands, and the distance between the two cylinder connecting rods connected to the cylinder increases. Under this action, the two sets of hinge fixing blocks and hinge rotating blocks distributed on the left and right sides move closer together in the center under the drive of the connecting rod, thereby driving the vehicle clamping arm fixed to the hinge rotating block to complete the clamping action; otherwise, the vehicle clamping arm opens.

[0031] In one embodiment, two pillars are provided in the middle of the transport vehicle body 1, and the top of each pillar is equipped with the horizontal steering joint 3. The end of the horizontal steering joint 3 is connected to a rocker arm 4 that can swing up and down.

[0032] In one embodiment, a sprocket 7 is provided at the other end of the rocker arm 4 and the end of the horizontal rotary switch 3. One of the sprockets is connected to the output shaft of a servo motor 6. The two sprockets are connected by a chain 8 to counteract the horizontal displacement change caused by the included angle of the rocker arm 4.

[0033] In one embodiment, the inner side of the clamping arm 12 is provided with a groove and a limiting block, which, together with the outer contour of the cigarette box, achieves all-round fixation.

[0034] In one embodiment, a motor-driven steering wheel 9 is mounted on the omnidirectional wheel at the rear, the motor-driven steering wheel 9 providing power for the movement of the transport vehicle body.

[0035] When using this invention, the operation is as follows, depending on the specific requirements:

[0036] 1. When it is necessary to clamp the moving smoke box, the vehicle moves to the appropriate position, the cylinder in the cylinder linkage mechanism 10 extends, so that the included angle of the clamping arm connected to it by the hinge is reduced. The rocker arm follows the clamping and keeps the included angle aligned with the vehicle under the adjustment of the horizontal rotation joint. The electric cylinder retracts, driving the rocker arm to rotate. The servo motor adjusts the clamping arm through the sprocket and chain to keep it horizontal. The spatial displacement caused by its horizontal swing is compensated by the extension and retraction of the electric cylinder.

[0037] 2. When the material in the smoke box needs to be poured out, the rocker arm is raised to an appropriate height under the action of the electric cylinder, and the servo motor drives the clamping arm to rotate through the sprocket and chain, so that the opening of the smoke box faces downward to complete the material pouring.

[0038] 3. When materials on the ground need to be loaded into the smoke box, the servo motor drives the clamping arm to rotate through the sprocket and chain, so that the smoke box opening faces forward. With the help of the rocker arm and the electric cylinder, the smoke box is pressed tightly against the ground. Then the vehicle moves forward to assist the manual shovel of materials on the roof into the smoke box.

[0039] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
