Description

Technical Field

[0001] This utility model relates to a pallet parking and positioning mechanism based on a pallet chain conveyor, belonging to the technical field of cigarette sorting equipment in the cigarette industry. Background Technology

[0002] In tobacco logistics sorting centers, almost the entire process relies on automated production lines. In these automated production lines, the various processes are connected by conveyor systems. During the transport of cigarette cartons or cases on pallets, some stages do not have high precision requirements for the pallet's placement, while others, such as automatic depalletizers, require higher precision. When a pallet containing cases of cigarettes is transported to the depalletizing station, the pallet stops, and then the suction cups on the automatic depalletizer pick up the cases of cigarettes from the pallet. If there is a significant deviation in the pallet's stopping precision, the suction cups may pick up non-target cigarettes along with the cases, leading to errors in the production process. Another example is the double-extension stacker crane, which can operate on two pallets simultaneously. However, it requires high positional accuracy between the two pallets. The pallet at the front can be fixed by the dead positioning mechanism at the front of the conveyor line. However, the second pallet currently relies on a control system to control the start and stop of the conveyor device to control the pallet's stopping position. This control method often results in the second pallet's stopping position not meeting the requirements, which can easily lead to errors and interruptions in the production process, affecting the sorting efficiency of cigarette cartons or cases. Utility Model Content

[0003] The purpose of this invention is to provide a pallet parking and positioning mechanism based on a pallet chain conveyor. This mechanism can ensure that the stopping position of the pallet meets the positioning accuracy requirements of cigarette cartons or cases, enabling the smooth sorting of cigarette cartons or cases.

[0004] The technical solution of this utility model is as follows: A pallet parking and positioning mechanism based on a pallet chain conveyor includes a mounting bracket arranged along the width direction of the pallet chain conveyor. The mounting bracket is located in the gap between two adjacent pallet chain conveyors and is fixed on its frame. Two sets of support members are arranged at intervals on the mounting bracket. Each set of support members includes at least two bearing support seats. Rotating shaft A and rotating shaft B are respectively inserted into the two sets of support members. One end of each rotating shaft is fixedly connected to a baffle. The two baffles are also connected together by a torsion arm. The other end of one of the rotating shafts is provided with a driven sprocket. The driven sprocket is connected to the driving sprocket via a chain. The driving sprocket is fixed on the output shaft of the drive motor. The drive motor is fixed on the mounting bracket.

[0005] In the aforementioned pallet parking and positioning mechanism based on a pallet chain conveyor, the mounting bracket includes two legs supported on two adjacent pallet chain conveyor frames, two mounting rods and a cross brace are connected between the two legs, two sets of support components are mounted on the two mounting rods, and a motor mounting plate is provided on the cross brace, with the drive motor fixed on the motor mounting plate.

[0006] In the aforementioned pallet parking and positioning mechanism based on a pallet chain conveyor, a switch bracket is also provided on the mounting rod, and a proximity switch A is provided on the switch bracket; a proximity switch B is also provided on the side of the mounting rod near the baffle, and the proximity switch B is located directly below the support member.

[0007] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model adopts the above-mentioned technical solution, which drives one of the rotating shafts to rotate by the rotation of the motor, and drives the baffle connected to it to rotate. The baffle drives another baffle to rotate around another rotating shaft through the torsion arm. The two baffles block the pallet, realizing the precise positioning of the pallet. This mechanism can ensure that the stopping position of the pallet meets the positioning accuracy requirements of the cigarette packs, so that the sorting of cigarette packs can be carried out smoothly and the sorting efficiency of cigarette packs can be improved.

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0014] An embodiment of this utility model: A pallet parking and positioning mechanism based on a pallet chain conveyor includes a mounting bracket 1 arranged along the width direction of the pallet chain conveyor. The mounting bracket 1 is located in the gap between two adjacent pallet chain conveyors and is fixed on its frame. Two sets of support members are arranged at intervals on the mounting bracket 1. Each set of support members includes two bearing support seats 2. A rotating shaft A3 and a rotating shaft B4 are respectively inserted into the two sets of support members. The rotating shafts are supported and fixed by the two bearing support seats 2, so that they can only rotate and cannot move longitudinally. One end of each rotating shaft is fixedly connected to a baffle 5. The two baffles 5 are also connected together by a torsion arm 6. The other end of one of the rotating shafts is provided with a driven sprocket 7. The driven sprocket 7 is connected to a driving sprocket 9 via a chain 8. The driving sprocket 9 is fixed on the output shaft of a drive motor 10. The drive motor 10 is fixed on the mounting bracket 1.

[0015] When it is necessary to stop and position the pallet 18 on the pallet chain conveyor, the drive motor 10 starts, driving the drive sprocket 9 to rotate. This drives the driven sprocket 7 to rotate via the chain 8. The driven sprocket 7 then drives one of the rotating shafts to rotate. This rotating shaft drives the baffle 5 connected to it to rotate. As the baffle 5 rotates, it drives the torsion arm 6 to move. During the movement of the torsion arm 6, it pulls another baffle 5 to deflect around another rotating shaft by an angle. Thus, the two baffles 5 block the pallet 18, achieving precise positioning of the pallet 18.

[0016] The mounting bracket 1 includes two gantry-structure legs 11 supported on two adjacent pallet chain conveyor frames. Two mounting rods 12 and a cross brace 13 are connected between the two legs 11. A total of four bearing support seats 2 of the two sets of support components are respectively installed on the two mounting rods 12. A motor mounting plate 14 is vertically arranged on the side of the cross brace 13, and the drive motor 10 is fixed on the motor mounting plate 14.

[0017] A switch bracket 15 is also provided at the middle position of the mounting rod 12, and a proximity switch A16 is provided on the switch bracket 15. Figure 1 As shown, when the baffle 5 deflects downwards and does not block the pallet 18, the torsion arm 6 is directly in front of the proximity switch A16. At this time, the proximity switch A16 is triggered, sending a signal to the control system. Upon receiving this signal, the control system indicates that the baffle 5 has been lowered into position, and the pallet chain conveyor can then transport the pallet 18 forward. A proximity switch B17 is also located on the side of the mounting rod 12 near the baffle 5, directly below the support member. Figure 2As shown, when the baffle 5 deflects to block the tray 18, the bottom of the baffle 5 is directly in front of the proximity switch B17. At this time, the proximity switch B17 is triggered and sends a signal to the control system. When the control system receives the signal, it means that the baffle 5 has deflected upward to the correct position. The control system will then control the drive motor 10 to stop rotating to ensure that the baffle 5 can block the tray 18.
