Technical Field

[0001] The utility model relates to the technical field of tobacco packaging, and more specifically, to a trademark paper lifting device. Background Art

[0002] Cigarette label paper is used for tobacco packaging, usually in the form of stacks, with hundreds of sheets in each stack, stacked vertically. In the process from the material tray to the paper warehouse of the tobacco packaging machine, the label paper often undergoes horizontal conveying, vertical lifting and other process flows. Usually, the vertical lifting design of the label paper is a single-package reciprocating lifting mechanism. The cache of the label paper stacks in the equipment generally adopts the form of horizontal belt conveyor, and the label paper cached on the horizontal belt is mostly in a continuous stacking state. When reversing the conveyor, it is often necessary to design an additional handover structure. These additionally designed handover structures usually have the following disadvantages:

[0003] Horizontal belt caching and vertical lifting generally occupy a large area and have low space utilization.

[0004] The trademark papers cached by the horizontal belt are mostly in a continuous stacked state, and the reversal requires the additional design of a transfer mechanism, which is rather troublesome.

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0026] The label paper lifting device is used to lift, buffer and convey the label paper. The material state is as follows: Figure 1 As shown, the trademark paper stack is composed of hundreds of trademark papers stacked together without any external constraints; it is easy to scatter and fall down under the action of external force, so multiple positioning and protection are required during its transportation and lifting process.

[0027] like Figure 2 As shown, the trademark paper lifting device has a horizontal channel 1 and an overhead channel 13, which are used for horizontal transportation, and the position of the overhead channel 13 is higher than the horizontal channel 1. The horizontal channel 1 and the overhead channel 13 are connected by a lifting mechanism. The horizontal channel 1 and the overhead channel 13 can be arranged as follows: Figure 3 As shown, the projections of the two on the same plane have an angle of 90°, or the projections of the two on the same plane are on the same straight line.

[0028] The lifting mechanism comprises a fixed plate 3, a transparent safety door 4, a guide plate 5, a lifting tray 6, a fixed block 7, a baffle (including a first baffle 8 and a second baffle 9), and a synchronous belt (including a first synchronous belt 10 and a second synchronous belt 11). The fixed block 7 is fixed on the synchronous belt, the lifting tray 6 is fixed on the fixed block 7, the fixed plate 3 is located below the transparent safety door 4 and the fixed plate 3 is fixed on the guide plate, the fixed plate 3, the transparent safety door 4, the guide plate 5 and the baffle enclose three sides of the lifting tray 6 to form a lifting channel, and the lifting tray 6 is located in the lifting channel.

[0029] The synchronous belt is installed on the roller, and a transmission shaft 17 is set at one end of the roller at the lower end of the synchronous belt. The transmission shaft 17 and the servo motor 15 transmit power through the belt 16. 20 lifting pallets 6 are set at equal distances on the synchronous belt. The first synchronous belt 10 and the second synchronous belt 11 are arranged in parallel, and each lifting pallet 6 is fixedly connected to the first synchronous belt 10 and the second synchronous belt 11 to stabilize the lifting pallet 6. The first baffle 8 and the second baffle 9 are arranged in parallel and located between the first synchronous belt 10 and the second synchronous belt 11 to play a supporting role.

[0030] The position of the lifting tray 6 facing the discharge end of the horizontal channel 1 is the material receiving station A, and the position of the lifting tray 6 facing the feed end of the high-altitude channel 13 is the vertex station B.

[0031] A push rod 18 driven horizontally by a servo electric cylinder 19 is arranged on the left side of the vertex station B. The high altitude channel 13 is located on the right side of the vertex station B. Therefore, the pushing direction of the push rod 18 is the material transmission direction of the high altitude channel 13.

[0032] A first photoelectric sensor 2 is arranged at the material receiving station A, and a second photoelectric sensor 12 is arranged at the vertex station B. An L-shaped bracket 14 is installed on the fixing plate 3 , and the first photoelectric sensor 2 is fixed on the bracket 14 .

[0033] A proximity sensor 20 is installed next to the lower end of the synchronous belt to detect whether the lifting tray has reached the origin through the proximity sensor, and the servo motor is controlled to ensure that the lifting tray is always at the origin after the servo motor 15 rotates half a circle. The origin is the position that the proximity sensor can detect.

[0034] The trademark paper is fed into the receiving station A of the lifting mechanism along the X direction through the horizontal channel 1, and the guide plate 5 positions it in the X direction; the fixed plate 3, the transparent safety door 4, the first baffle 8, and the second baffle 9 position it in the Y direction; the lifting tray 6 holds it and positions it in the Z direction.

[0035] When the first photoelectric sensor 2 detects that the trademark paper has been delivered to the position, the lifting mechanism performs the lifting action; during the lifting process, the servo motor 15 transmits power to the belt 16, and then the belt 16 transmits power synchronously to the first synchronous belt 10 and the second synchronous belt 11 through the transmission shaft 17. The first synchronous belt 10 and the second synchronous belt 11 lift the trademark paper upward by one station, and the next lifting tray 6 arrives at the receiving station A to wait for the horizontal channel 1 to deliver the next stack of trademark paper. At this time, the servo motor 15 stops running. During the normal operation process, every time a stack of trademark paper is pushed over by the horizontal channel 1, the trademark paper in the lifting channel will rise by one station, and correspondingly, the transmission shaft 17 rotates 180° (that is, each time the transmission shaft 17 rotates half a circle, the lifting channel rises by one station); the lifting channel can accommodate eight stacks of trademark paper at the same time, and it also has the function of caching trademark paper while lifting. The lifting tray 6 is fixed to the first synchronous belt 10 and the second synchronous belt 11 through the fixing block 7, and moves with the synchronous belt.

[0036] In addition, in order to ensure the accuracy of the pallet in the Z direction in the lifting device and eliminate the cumulative error during operation, the lifting device will return to the origin through the proximity sensor 20 on the lower side every time it is lifted a distance (usually a multiple of the single-station distance); thereby ensuring that the pallet positions at the receiving station A and the vertex station B are accurate, thereby improving the safety and stability of the two handover positions.

[0037] When the label paper is lifted to the top station B, the second photoelectric sensor 12 installed on the guide plate 5 detects that the label paper is lifted to the position and returns to the origin for calibration. Then, the push rod 18 in the waiting state pushes the label paper at the top station B into the high-altitude channel 13 and feeds the tobacco packaging machine under the action of the servo electric cylinder 19. Before the next stack of label paper at the top station B is lifted to the position, the push rod 18 returns to the initial position on the left to wait for the next stack of label paper to be lifted to the position.

[0038] A transparent safety door 4 is installed in front of the lifting device, which can be used to position the label paper in the Y direction during the lifting process. Its transparent material makes it convenient for the operator to observe the status of the label paper cached in the lifting device, and also facilitates timely handling of abnormalities and workers to inventory the label paper materials when changing shifts. In addition, the worker can open the safety door to sort and maintain the label paper in the lifting device.

[0039] In the initial state, when there is no cached trademark paper material in the lifting device, in order to quickly feed the tobacco packaging machine, when the first stack of trademark paper is sent to the material receiving station A of the automatic lifting device through the horizontal channel 1, the servo motor 15 quickly lifts the trademark paper at the material receiving station A to the top station B without caching in the lifting device. After the supply of trademark paper materials meets the production needs of the tobacco packaging machine, the servo motor 15 reduces the lifting speed of the lifting tray; and then during the lifting process, the empty cache stations are dynamically filled, and the empty cache stations are gradually filled until all 8 cache stations are filled. At this time, the lifting cache device will run at a single speed, and then according to the material requirements of the tobacco packaging machine, one station will be fixedly lifted each time, and the material will be matched according to the speed of the tobacco packaging machine.

[0040] In addition, when horizontal channel 1 cannot deliver materials to receiving station A in a short period of time due to equipment alarm or manual maintenance, the materials buffered in the lifting channel can run independently without stopping, continuously ensuring the material demand of the tobacco packaging machine until all 8 buffer stations are consumed. Figure 3 As shown, the trademark paper is transported along the X direction in the horizontal channel 1. When the trademark paper enters the material receiving station of the lifting device, it starts to be lifted in the Z direction. After being lifted to the vertex station B, it is pushed into the high-altitude channel 13 and transported along the Y direction, realizing the reversing transportation of the trademark paper, making full use of the idle space of the tobacco packaging machine, and not occupying the operating space of the operator, thereby effectively improving the space utilization rate.

More specifically, within the scope disclosed in the present application, multiple variations and improvements can be made to the components and / or layout of the subject combination layout. In addition to the variations and improvements made to the components and / or layout, other uses will also be obvious to those skilled in the art.
