[0021] Figure 1 It is a schematic diagram (I) of the overall structure of the tobacco box unpacking and stacking production line provided by an embodiment of the present invention;

[0022] Figure 2 It is a schematic diagram (II) of the overall structure of the tobacco box unpacking and stacking production line provided by an embodiment of the present invention. Detailed implementation manners

[0023] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0024] The present invention provides an embodiment of a tobacco box unpacking and stacking production line, specifically as Figures 1 to 2 shown, including: a loading station 1, a transfer mechanism 2, a conveyor belt 3, a clamping and tipping mechanism 4, a tobacco box export conveyor platform 5, a tobacco box pushing-down mechanism 6, a pressing and stacking mechanism 7, a bottom-opening mechanism 8, a recycling and stacking device 9, and a pallet recycling mechanism 10 that cooperate with each other and transfer the tobacco boxes in sequence; among them, the loading station 1 is used to store tobacco boxes, the transfer mechanism 2 is used to transfer the tobacco boxes to the conveyor belt 3, the conveyor belt 3 is used to connect the transfer mechanism 2 and the clamping and tipping mechanism 4, the clamping and tipping mechanism 4 is used to pour out the tobacco, the tobacco box pushing-down mechanism 6 is used to push down the tobacco boxes, the pressing and stacking mechanism 7 is used to flatten the empty tobacco boxes, the bottom-opening mechanism 8 is used to assist in flattening the tobacco boxes, and the recycling and stacking device 9 is used to recycle the flattened tobacco boxes. The pallet recycling mechanism 10 is used to recycle the empty pallets on the loading station 1.

[0025] The feeding station 1 includes a frame body and a number of parallel rollers 1-1 for moving the tobacco bale boxes (and their corresponding pallets), and a second pallet conveyor belt 1-2 is further provided on the frame body. A pallet recycling mechanism 10 is arranged on one side of the feeding station 1. A first pallet conveyor belt 10-2 corresponding to the second pallet conveyor belt 1-2 is arranged on the bracket 10-1 of the pallet recycling mechanism 10. A pallet stacking mechanism 10-3 capable of vertically moving along the bracket 10-1 is further arranged on the bracket 10-1. The pallet stacking mechanism 10-3 can be driven by a driving mechanism to move. It is used to receive and lift pallets (or pallet stacks). For example, when a new pallet needs to be stacked at the pallet recycling mechanism 10, the pallet stacking mechanism 10-3 moves to the lowest end, supports the bottommost pallet and then moves upward to vacate the space at the bottom, facilitating the new pallet to be sent from the second pallet conveyor belt 1-2 to the first pallet conveyor belt 10-2.

[0026] The transfer mechanism 2 includes a truss 2-1, a linear walking mechanism 2-2 and a rotary grasping device 2-3. The linear walking mechanism 2-2 can be installed on the truss 2-1 and can also be driven by a driving mechanism to move along the truss 2-1. The rotary grasping device 2-3 (which can be but is not limited to using suction cups in implementation) is installed on the linear walking mechanism 2-2 and is used to grasp the tobacco bale boxes, and cooperate with the rotary action and the linear walking mechanism 2-2 moving along the truss 2-1 to achieve the function of transferring the tobacco bale boxes.

[0027] The transfer mechanism 2 is connected to the conveyor belt 3. The conveyor belt 3 is used to connect the transfer mechanism 2 and the clamping and tipping mechanism 4. That is, after the transfer mechanism 2 transfers the tobacco bale boxes from the feeding station 1 to the conveyor belt 3, the conveyor belt 3 transports the tobacco bale boxes to the subsequent clamping and tipping mechanism 4. Preferably, the conveyor belt 3 can be an L-shaped conveyor belt, and a guiding mechanism for guiding the moving direction of the tobacco bale boxes during the transportation process can also be arranged on the conveyor belt 3. The guiding mechanism can be referred to the figure shown. Guide plates are respectively arranged on both sides of the conveyor belt 3, and the guide plates preferably adopt a zigzag shape to facilitate the tobacco bale boxes to be input from the larger opening to the conveyor belt.

[0028] The clamping and unloading mechanism 4 has a structure similar to that of a manipulator, specifically comprising a rotating bracket 4-1 and a clamping double arm 4-2 installed on the rotating bracket 4-1, the clamping double arm 4-2 can move up and down along the rotating bracket 4-1, and a motion cylinder for driving the clamping double arm 4-2 to reciprocate vertically is installed in the rotating bracket 4-1, so that the rotating bracket 4-1 can drive the clamping double arm 4-2 to run between the conveyor belt 3 and the tobacco box outlet conveying platform 5; a clamping panel 4-3 is installed at the clamping end of the clamping double arm 4-2, preferably, an anti-slip device is provided on the inner side of the clamping panel 4-3, such as but not limited to a rubber pad, and the clamping panel 4-3 can also be powered by a cylinder.

[0029] The tobacco box pushing mechanism 6 is installed above the tobacco box exporting and conveying platform 5. The tobacco box pushing mechanism 6 specifically includes a cross bar arranged above the tobacco box exporting and conveying platform 5. When the empty tobacco box passes through this position, the cross bar blocks the tobacco box so that the tobacco box is turned from a vertical position to a horizontal position, and the opening side of the tobacco box faces outward. Both sides of the tobacco box exporting and conveying platform 5 are also provided with retaining edges 6-1 for preventing the empty tobacco box from falling after tipping over.

[0030] The stacking mechanism 7 includes a tobacco box bidirectional transmission mechanism 7-1 arranged at the end of the tobacco box outlet conveying platform 5 and a stacking cylinder 7-3 and a roller 7-2 arranged above the tobacco box bidirectional transmission mechanism 7-1. The roller 7-2 is installed at the bottom end of the stacking cylinder 7-3. The stacking cylinder 7-3 is vertically arranged. By moving the stacking cylinder 7-3 downward, the roller 7-2 flattens the empty tobacco box.

[0031] The box bottom opening mechanism 8 is arranged at the tail end of the tobacco box bidirectional transmission mechanism 7-1, and the box bottom opening mechanism 8 includes a horizontal translation cylinder 8-1 and a transverse opening cylinder 8-2. The transverse opening cylinder 8-2 is installed at the moving end of the horizontal translation cylinder, and the supporting arms at both ends of the transverse opening cylinder 8-2 are opened to the transverse ends. During operation, the mechanism is matched with the stacking mechanism 7.

[0032] The recovery stacking device 9 is arranged on one lateral side of the bidirectional transmission mechanism of the tobacco box, and is used for storing the folded empty tobacco boxes.

[0033] The specific working process can be referred to as follows:

[0034] The tobacco boxes stacked on the pallet are transported to the loading station 1, and the transfer mechanism 2, with the cooperation of the truss and the linear walking mechanism, moves the rotating grasping device to the top of the tobacco box 11 to be grasped, accurately grasps the tobacco box 11 and transfers it to one end of the conveyor belt 3. In addition, the empty pallet after the tobacco box is taken away is transported to the pallet recovery mechanism 10; continuing from the previous text, the tobacco box is transported to the clamping and unloading mechanism 4 through the conveyor belt 3, the clamping and unloading mechanism 4 clamps and lifts the tobacco box, and the staff cuts open the bottom opening of the tobacco box 11. After the tobacco (cigarette packs) in the box are poured out by gravity, the clamping and unloading mechanism 4 rotates a preset angle to transfer the empty tobacco box to the tobacco box export conveying platform 5, and the tobacco box export conveying platform 5 transports the empty tobacco box When the cross bar of the pushing mechanism 6 is in the position, the tobacco box is pushed down to a horizontal state with the opening facing the box bottom opening mechanism 8. The retaining edges 6-1 on both sides of the tobacco box lead-out conveying platform 5 can prevent the tobacco box from tipping over to the side. Preferably, the retaining edge 6-1 adopts the folding structure shown in the figure (for example, a folding plate with an inclined structure on the upper part) so that the clamping and unloading mechanism 4 can smoothly place the empty cigarette box on the tobacco box lead-out conveying platform 5; then the tobacco box is conveyed to the two-way transmission mechanism 7-1, and under the joint action of the box bottom opening mechanism 8 and the stacking mechanism 7, the tobacco box 11 is flattened and folded, and then, driven by the two-way transmission mechanism 7-1, the flattened and folded tobacco box is conveyed to the recovery and stacking device 9 to complete the recovery of the tobacco box.

[0035] The driving methods of the electric control, pneumatic control, signal sensing, transporting, flipping, clamping, grabbing and releasing actions involved in the above process can all refer to the mature related technologies in the industrial field, and the present invention does not limit or elaborate on this.

[0036] In summary, the design concept of the present invention is to form a production line operation for the loading, unstacking, transporting, dumping, laying down, folding, and recycling of tobacco boxes. Specifically, the transport mechanism transports the tobacco box to be processed to the conveyor belt, and the conveyor belt sends it to the clamping mechanism. The clamping mechanism picks up the tobacco box and pours out the tobacco and sends it to the subsequent conveying platform. The empty tobacco box is then pushed down by the pushing mechanism and transported to the stacking mechanism and the box bottom opening mechanism. The stacking mechanism flattens the empty tobacco box, and the box bottom opening mechanism opens the opening of the empty tobacco box while flattening. The two cooperate to realize the flattening and folding of the empty tobacco box, and finally the stacking mechanism transmits it to the tobacco box recovery stacking device to complete the entire recycling process of the tobacco box. The present invention can be processed in an automated manner throughout the process, and the recycling of tobacco boxes can be completed efficiently without too much participation of personnel.
