The existing workshops generally perform stacking, handling and stacking work manually. In order to reduce the labor intensity of employees and improve the efficiency of stacking and handling of cigarette label paper, it is necessary to design a special device for stacking and picking cigarette label paper to complete this repetitive work.

DETAILED DESCRIPTION

[0023] like Figure 1-8 As shown, this embodiment provides a cigarette label paper stacking and picking device, including a controller, a stacking moving mechanism 1, a transport plate 2 connected to the driving end of the stacking moving mechanism 1, two flipping clamping mechanisms 3 installed on the transport plate 2, and a plurality of negative pressure suction cups 4, the flipping clamping mechanism 3 includes a flipping cylinder 31 and a clamping assembly 33, the clamping assembly 33 includes a rotating plate 331, a clamping push plate 333 and a push plate cylinder 335 arranged between the rotating plate 331 and the clamping push plate 333, the push plate cylinder 335 is installed on the rotating plate 331, the output end of the push plate cylinder 335 is fixedly connected to the clamping push plate 333, and a pressure sensor (not shown) for detecting the pressure on the paper stack is provided on the clamping push plate 333, the controller is used to control the stacking moving mechanism 1, the flipping clamping mechanism 3, the negative pressure suction cup 4 and receive the pressure sensor signal.

[0024] Specifically, the flip cylinder 31 is rotatably connected to the end of the transport plate 2, and the rotating plate 331 is located between the flip cylinder 31 and the transport plate 2. The transport plate 2 includes a transport plate body 21 and a support 23 extending upward from both ends of the transport plate body 21. The flip cylinder 31 is rotatably connected to the support 23 at the end of the transport plate 2. The output end of the flip cylinder 31 is rotatably connected to the cylinder connecting shaft 3311 on one side of the rotating plate 331 through a joint bearing. At the same time, the side of the rotating plate 331 facing the paper stack extends to form a rotating core shaft 3312, and the rotating core shaft 3312 is rotatably connected to the end of the transport plate body 21 through a bearing 3313. Two flip clamping mechanisms 3 are symmetrically distributed at both ends of the transport plate 2. A plurality of negative pressure suction cups 4 are evenly installed on the side of the transport plate 2 facing the top of the paper stack, and the top of the negative pressure suction cup 4 is connected to the negative pressure pump in the workshop through an air pipe.

[0025] In this embodiment, the stacking moving mechanism 1 includes a connecting seat 11 and a vertical driving mechanism and a horizontal driving mechanism arranged on the connecting seat 11. The vertical driving mechanism includes two vertical guide rods 12, a screw rod 13 and a screw driving motor. The screw driving motor is arranged in the connecting seat 11. The vertical guide rod 12 and the screw rod 13 respectively pass through the connecting seat 11 in the vertical direction and are respectively fixedly connected to the conveying plate 2. The screw driving motor can drive the screw rod 13 up and down by rotating, and then the screw rod 13 drives the conveying plate 2 and the flip clamping mechanism 3 and the negative pressure suction cup 4 on the conveying plate 2 to move up and down. The two vertical guide rods 12 play a guiding role, so that the overall movement of the conveying plate 2 is more stable, and the connecting seat 11 is slidably connected with the vertical guide rod 12. The horizontal driving mechanism includes two horizontal guide rods 15, gears, racks 16 and gear drive motors. The gears and gear drive motors are arranged in the connecting seat 11. The horizontal guide rods 15 and the racks pass through the connecting seat 11 in the horizontal direction respectively. The gears, racks 16 and gear drive motors cooperate to form a gear-rack linear reciprocating mechanism. The horizontal guide rods 15 and the racks are fixedly mounted on the frame. The gear drive motor can drive the gears to perform linear reciprocating motion along the racks 16 by rotation, and then the connecting seat 11 and the vertical driving mechanism connected to the connecting seat 11, the transport plate 2 and other structures perform linear reciprocating motion in the horizontal plane. The two horizontal guide rods 15 play a guiding role to make the overall movement more stable. The connecting seat 11 is slidably connected to the horizontal guide rods 15. Expressed in terms of a spatial rectangular coordinate system, the driving direction of the vertical drive mechanism is the z direction, and the driving direction of the horizontal drive mechanism is the x direction. In other embodiments, the stacking moving mechanism 1 may further be provided with a third drive mechanism that drives in a horizontal plane in a direction perpendicular to the driving direction of the horizontal drive mechanism (i.e., the y direction). The horizontal guide rod 15 and the rack of the horizontal drive mechanism are no longer fixed on the frame, but the horizontal drive mechanism is installed on the driving end of the third drive mechanism, so that the cigarette label paper stacking and picking device can realize arbitrary movement in three dimensions and has higher picking flexibility.

[0026] This embodiment picks up the paper stack group and the interlayer corrugated paper. The specific picking principle is as follows: when the paper stacks 5 of the specified number of groups reach the predetermined position, the controller triggers the picking signal, and the stacking moving mechanism 1 moves to the picking station of the paper stack group according to the picking signal to start picking up the paper stack group. When picking up the paper stack group, Figure 2-4 As shown, the flip cylinder 31 is in an extended state, driving the rotating plate 331 to flip downward, and the clamping push plates 333 at both ends clamp the paper stack group in the middle. The push plate cylinders 335 on both sides extend out, pushing the clamping push plates 333 to clamp the paper stack group while making the position of all paper stacks 5 more compact. The stroke of the push plate cylinder 335 is adjusted according to the measured value of the pressure sensor on the clamping push plate 333. After the flip clamping mechanism 3 completes the clamping, the negative pressure pump works to form a negative pressure at the negative pressure suction cup 4 connected to the negative pressure pump through the air pipe, completing the suction of all paper stacks 5. Then, the stacking moving mechanism 1 is activated to pick up the paper stack group to the stacking position. When the stacking of a layer of paper stack group is completed, a layer of corrugated paper 6 needs to be laid. The stacking moving mechanism 1 moves to the suction station of the corrugated paper 6 according to the suction signal and starts to suck the corrugated paper 6, as shown in FIG. Figure 7-8 As shown, at this time, the flip cylinder 31 contracts, driving the rotating plate 331 to flip upward, thereby making the lower surface of the negative pressure suction cup 4 at the lowest position, avoiding the collision between the flip clamping mechanism 3 and the corrugated paper 6, and the negative pressure pump works to form a negative pressure at the negative pressure suction cup 4 to complete the absorption of the corrugated paper 6, and then, the stacking moving mechanism 1 is activated to pick up the corrugated paper 6 to the stacking position.

[0027] The cigarette label paper stacking and picking device of the utility model is adapted to the actual stacking needs of cigarette label paper. It can not only stably pick up grouped paper stacks but also pick up the interlayer corrugated paper required for cigarette label paper stacking. There is no need to additionally configure staff to lay the interlayer corrugated paper. The flip clamping mechanism cooperates with the negative pressure suction cup for picking up, and stable picking can be achieved even when the number of paper stacks is large and the weight is heavy, which reduces the labor intensity of employees and improves the stacking and handling efficiency of cigarette label paper.
