Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of box sealing equipment, in particular to a cigarette box stacking height compensating device. Background Art
[0002] In a cigarette factory, the carton sealing machine, as the last link of the entire production line, plays a key role in the quality of the factory's finished products and the efficiency of the workshop operation. At present, most factories rely on robots to suck the folded cigarette boxes and send them to the next link. However, when the cigarette boxes are folded, the overlap between the two adjacent cardboards of the cigarette boxes forms a crease. When the folded cigarette boxes are placed horizontally, the two adjacent cardboards cannot be guaranteed to be flat due to the overlap of the cardboards, forming a horizontal cardboard and a sloped cardboard. This directly causes the robot to fail to suck the cigarette boxes due to its unevenness when sucking the stacked cigarettes, thereby affecting the production efficiency. The greater the slope of the sloped cardboard, the easier it is to affect the robot's suction. In severe cases, it will cause the carton sealing machine to stop, and then affect the upper connected machine. Therefore, it is urgent to invent a device that can be used to compensate for the stacking of cigarette boxes to make the upper surface of the cigarette box stacking flat. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.
[0024] In the description of the present invention, it should be noted that the term "including" and its variations represent open inclusion, that is, "including but not limited to". In addition, in the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically limited.
[0025] The utility model provides a 4-height stacking compensation device for stacking cigarette boxes, referring to Figure 1-Figure 3 As shown, it includes a support base 1, a support frame 2, a lifting mechanism and a compensation mechanism; the support frame 2 is arranged at the output end of the lifting mechanism, and is used to support the cigarette box stack 4; the lifting mechanism is arranged on the support base 1, and is used to drive the support frame 2 to rise and fall; the compensation mechanism is arranged at the bottom of the support frame 2 to support one side of the slope of the cigarette box stack 4, and is used to lift the slope of the cigarette box stack 4, so that the slope cardboard 42 of the top layer of the cigarette box stack 4 is turned upward along the fold 43 to the horizontal, so that the upper surface of the cigarette box stack 4 is flat, which is convenient for the robot to suck the cigarette box.
[0026] Specifically, in one embodiment of the utility model, the lifting mechanism includes a chain, a sprocket group and a driving motor, wherein the sprocket group is arranged at the output end of the driving motor; the chain is arranged vertically and is connected to the sprocket group by transmission; the support frame 2 is fixedly arranged on the chain. The driving motor drives the sprocket group to rotate, and the sprocket group drives the chain to be transported up and down, thereby driving the lifting of the support frame 2. The lifting of the support frame 2 is stable, and the stacked cigarette boxes can be prevented from sliding due to shaking and tilting.
[0027] In one embodiment of the present invention, reference Figure 1As shown, the support frame 2 includes a longitudinal beam 21 and three cross beams 22 evenly distributed along the longitudinal beam 21 and perpendicular to the longitudinal beam 21. Specifically, the longitudinal beam 21 can be fixedly set on the chain, and the three cross beams 22 are set on the same side of the longitudinal beam 21. When the support frame 2 descends, the longitudinal beam 21 descends to the outside of the end of the conveying roller, and the three cross beams 22 can fall into the gap between two adjacent conveying rollers, so as to facilitate the conveying of the cigarette box stack 4 onto the support frame 2 through the conveying roller. Preferably, the support seat 1 can be set to be L-shaped.
[0028] The compensation height of the compensation mechanism, i.e., the height of one side of the slope of the cigarette box stacking 4, can be set according to the number and height of the cigarette boxes in the cigarette box stacking 4, so that when the compensation mechanism lifts the cigarette box stacking 4, the sloped paperboard 42 of the top cigarette box in the cigarette box stacking 4 can be turned upward along the fold 43 to be roughly horizontal, so that the upper surface of the cigarette box stacking 4 is roughly flat, which is convenient for the robot to suck the cigarette box. The whole stack of cigarette box stacking 4 generally places 10-20 cigarette boxes, and accordingly, the height of the whole stack of cigarette box stacking 4 lifted by the compensation mechanism is 400-450mm. For example, the height of the whole stack of cigarette box stacking 4 lifted by the compensation mechanism can be set to 400mm, 410mm, 420mm, 430mm, 440mm, 450mm, etc. As the cigarette boxes are sucked by the robot, the inventory of cigarette boxes on the support frame 2 decreases, and the slope of the sloped paperboard 42 of the top cigarette box in the cigarette box stacking 4 decreases. When the cigarette boxes in the cigarette box stacking 4 are reduced from a whole stack to a half stack, the suction of the robot is affected. When the number of cigarette cases in the whole stack of cigarette cases palletizing 4 is an even number, the half stack of cigarette cases palletizing 4 is the number of cigarette cases reduced to half of the number of cigarette cases in the whole stack of cigarette cases palletizing 4 or the height of the cigarette cases palletizing 4 is reduced to half of the height of the whole stack of cigarette cases palletizing 4. When the number of cigarette cases in the whole stack of cigarette cases palletizing 4 is an odd number, the half stack of cigarette cases palletizing 4 is half of the number of cigarette cases in the whole stack of cigarette cases palletizing 4 minus 1. For example, the number of cigarette cases in the whole stack of cigarette cases palletizing 4 is 10, the number of cigarette cases in the half stack of cigarette cases palletizing 4 is 5, the number of cigarette cases in the whole stack of cigarette cases palletizing 4 is 15, and the number of cigarette cases in the half stack of cigarette cases palletizing 4 is 7. In order to make the sloped paperboard 42 of the top layer of the cigarette cases in the remaining half stack of cigarette cases palletizing 4 still be able to remain roughly horizontal, the lifting height of the compensation mechanism can be reduced accordingly. Preferably, the height of the half stack of cigarette cases palletizing raised by the compensation mechanism is 20-50mm lower than the height of the whole stack of cigarette cases palletizing. For example, when the cigarette boxes of the cigarette box stacking 4 are reduced from a full stack to a half stack, the lifting height of the compensation mechanism can be reduced by 20mm, 30mm, 40mm or 50mm, etc. In this way, the upper surface of the cigarette box stacking 4 can be kept roughly flat during the entire suction process, thereby improving the suction efficiency of the manipulator. Of course, during use, the compensation height of the compensation mechanism can also be obtained through debugging.
[0029] In one embodiment of the utility model, the compensation mechanism includes a plurality of cylinders 3, each of which is arranged along the width direction of the slope of the cigarette box stacking 4 to lift the sloped paperboard 42 of the cigarette box evenly. Preferably, a support plate 31 can also be provided at the output end of the piston rod of the cylinder 3 to increase the contact area between the cylinder 3 and the cigarette box stacking 4, so that the lifting is more stable. The cylinder 3 is arranged at the bottom of the support frame 2. When the piston rod of the cylinder 3 retracts, the support plate 31 is lower than the upper surface of the support frame 2, so that the cigarette box stacking 4 can be smoothly transported to the support frame 2. When the piston rod of the cylinder 3 is extended, the bottom layer of the cigarette box stacking 4 is lifted upward, and the sloped paperboard 42 of the bottom layer of the cigarette box is folded upward along the fold 43, and then the upper layer of the cigarette box is lifted. In this way, layer by layer, the lower layer of the cigarette box lifts the sloped paperboard 42 of the upper layer of the cigarette box until the sloped paperboard 42 of the top layer of the cigarette box is turned upward along the fold 43 to the horizontal, so that the upper surface of the cigarette box stacking 4 is flat. Preferably, the number of the cylinders 3 includes two, which are respectively arranged at the two ends of the width direction of the slope of the cigarette box stacking 4. Specifically, the two cylinders 3 can be respectively arranged on the inner side of the crossbeam 22 located at the two ends, and can respectively support the two ends of the width direction of the slope of the cigarette box stacking 4, so that the support is stable and cost-saving, and the two cylinders 3 can fall into the gap between two adjacent conveying rollers with the support frame 2. The air source of the cylinder 3 can use the workshop air source, which is easy to obtain. According to the specifications of the cigarette boxes and the number of cigarette boxes in each cigarette box stacking 4, the elongation of the piston rod of the cylinder 3 can be flexibly controlled, thereby controlling the compensation amount of the compensation device, and realizing the height compensation of the cigarette box stacking 4 with different specifications and different numbers of cigarette boxes stacked, which has strong applicability.
[0030] Preferably, the compensation mechanism further includes a solenoid valve and an air delivery pipe, the air delivery pipe includes a main pipe and a branch pipe, each of the cylinders 3 is connected in parallel through the branch pipe, each of the branch pipes is connected to the main pipe, and the solenoid valve is arranged on the main pipe. The solenoid valve controls the intake and exhaust of the two cylinders 3 at the same time, so that the piston rods of the two cylinders 3 are extended and retracted at the same time, and the slope of the cigarette box stacking 4 is lifted steadily.
[0031] The compensation device also includes a controller, and the cylinder 3, solenoid valve and drive motor are all electrically connected to the controller. The operation of the drive motor, the stroke of the cylinder 3 and the on-off of the solenoid valve can be controlled by the controller. The controller can be set separately or integrated in the control system of the carton sealing machine.
[0032] The working process of the compensation device is:
[0033] When the cigarette box stack 4 is transported to the suction station, the lifting mechanism on the support base 1 lowers the support frame 2 to the lowest position and keeps it at the bottom of the support base 1. At the same time, the piston rod of the cylinder 3 remains in a retracted state, and the support plate 31 is lower than the upper surface of the support frame 2. The cigarette box stack 4 is transported to the support frame 2 with the conveying roller and placed. Figure 2When the uneven cigarette box stack 4 enters the support frame 2, the cylinder 3 enters the working state, the piston rod of the cylinder 3 extends, and lifts up one side of the slope of the cigarette box stack 4, so that the slope cardboard 42 of the top cigarette box of the cigarette box stack 4 can be turned upward along the fold 43 to be roughly horizontal, so that the upper surface of the cigarette box stack 4 is roughly flat, so that the robot can smoothly suck the cigarette box and perform folding and filling work, as shown in FIG. Figure 3 As shown. As the cigarette boxes are sucked, the stock of cigarette boxes on the support frame 2 decreases. During production, the lifting mechanism drives the support frame 2 to gradually rise, and the support frame 2 gradually rises with the cigarette box stack 4, ensuring that the upper surface of the cigarette box stack 4 and the manipulator remain on the same working surface as a whole, thus realizing the supply of cigarette boxes. When the entire stack of cigarette boxes is used up, the cylinder 3 enters the closed state, the piston rod of the cylinder 3 retracts, and the lifting mechanism drives the support frame 2 to descend to the lowest position to replenish the new cigarette box stack 4.
[0034] The compensation device has a simple structure. By compensating the height difference between the sloped cardboard 42 and the horizontal cardboard 41 of the cigarette box stack 4, the upper surface of the folded cigarette box stack 4 tends to be flat, which greatly improves the efficiency of the carton sealing machine robot in sucking cartons and greatly reduces the failure downtime rate of the carton sealing machine.
[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
