Description

Technical Field

[0001] This utility model relates to the field of pallet conveying technology, specifically to a multi-row chain pallet conveying device. Background Technology

[0002] In the field of pallet conveying, chain conveyors have long been one of the mainstream solutions due to their classic and reliable characteristics. These devices typically move pallets by directly dragging the bottom beam of the chain plate with a chain, and are widely used in conjunction with equipment such as palletizers.

[0003] In the actual production process, there are clear and critical conveying requirements: on the one hand, empty pallets need to be accurately conveyed from the supply area to the designated palletizing position under the palletizer to prepare for subsequent palletizing operations; on the other hand, after the palletizer completes the palletizing operation, the pallets full of products also need to be smoothly conveyed away from the palletizing position to ensure the continuous operation of the production line.

[0004] However, traditional pallet conveying devices mostly use a single-row chain drive structure. When faced with heavy-duty pallets with outriggers, the small contact area between the pallet and the conveyor line makes slippage easy, leading to decreased conveying accuracy and affecting conveying efficiency. At the same time, traditional devices have poor adaptability to different pallet specifications, making it difficult to meet the diverse pallet transportation needs in production. This limitation is even more obvious in scenarios requiring larger load conveying, which may cause production line downtime and reduced overall efficiency. Utility Model Content

[0005] In view of the problems existing in the above-mentioned multi-row chain pallet conveyor devices, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a multi-row chain pallet conveying device, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A multi-row chain pallet conveyor includes a pallet, a power transmission system, a support and fixing system, a protection and detection system, and a wiring system. The power transmission system includes a geared motor, a torque arm, a heavy-duty shaft, four rows of sprockets, four rows of chains, guide wheels, a sprocket central shaft, a tension wheel, a support rail, a bearing seat, and a fixing ring. The geared motor is mounted on the support and fixing system via the torque arm and connected to the heavy-duty shaft. The four rows of sprockets are fixed to the heavy-duty shaft and mesh with the four rows of chains. The guide wheels include an inner guide wheel and an end guide wheel. The inner guide wheel is fixed to the support and fixing system via the sprocket central shaft and the support rail. The end guide wheel is fixed to the bearing seat and secured by the fixing ring. The tension wheel cooperates with the support rail and the guide wheel to keep the four rows of chains in a taut state. The support and fixing system is used to install and fix the various components and support the load. The protection and detection system is used for pallet conveying safety protection and position detection. The wiring system is used for overall machine wiring.

[0008] Preferably, the support and fixing system includes outriggers, foot plates, square tube cross braces, body tubes, support rods, seated bearings, track pads, and heavy-duty cover plates; the outriggers are fixed to the ground by the foot plates, the square tube cross braces are installed in the middle of the outriggers to maintain spacing, the body tubes are bolted to the outriggers, the seated bearings are connected to the sprocket guard plate and used to fix the heavy-duty shaft, the support rods cooperate with the sprocket guard plate to fix the tension wheel, the track pads and the heavy-duty cover plates rest on the guardrail short tubes, and the four rows of chains are laid on the track pads.

[0009] Preferably, the protective detection system includes a guardrail short tube, a guardrail, a photoelectric switch, and an on / off switch; the guardrail short tube is inserted horizontally into the machine body tube, the guardrail is installed on the guardrail short tube, the photoelectric switch is installed on the guardrail short tube and is used to detect whether the pallet is in place, and the on / off switch is used to control the disconnection and start-up of a single section of the conveyor line.

[0010] Preferably, the wiring system includes a cable tray mounting plate and a grid cable tray, wherein the cable tray mounting plate is mounted on the support leg and the grid cable tray is fixed to the cable tray mounting plate.

[0011] Preferably, it also includes a connecting plate, which is used to connect a single section of the conveyor line to the next section of the conveyor line; and the number of chains in the multi-row chain can be adjusted according to the load to adapt to the transportation needs of pallets of different specifications and prevent the pallets from slipping during the transportation process.

[0012] Preferably, when the pallet is a type with support legs, the load on the pallet and the products above it is supported by four rows of chains; when the pallet is a flat pallet, the heavy-duty cover plate can bear part of the load to ensure the stability of the conveying process.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model adopts a multi-row chain drive design in the power transmission system, which greatly increases the contact area with the pallet compared with the traditional single-row chain conveyor. This effectively makes up for the problem of slippage of heavy-duty pallets with legs due to small contact area, ensuring the stability and accuracy of pallet conveying and guaranteeing the efficient, stable and continuous operation of the palletizing system.

[0014] 2. This utility model allows for flexible adjustment of the number of chains in multiple rows according to actual load requirements, and is compatible with both supported pallets and flat pallets. Supported pallets directly bear the load through multiple rows of chains, while flat pallets can be partially supported by heavy-duty cover plates, thus meeting the transportation needs of various pallet specifications and improving the applicability of the device in different production scenarios.

[0015] 3. This utility model integrates a protection and detection system with a wiring system. The guardrail and guardrail short pipe work together to achieve safe protection for pallet conveying. The photoelectric switch accurately detects the pallet's position, and the on / off switch conveniently controls the start and stop of a single section of the conveyor line. At the same time, the grid cable tray is fixed by the cable tray mounting plate to achieve neat wiring of the whole machine, which not only ensures production safety but also improves the convenience of equipment operation and maintenance, and further helps to improve the efficiency of the production line.
