Description

Technical Field

[0001] This utility model relates to a conveyor line for transporting workpieces, and more particularly to a support device installed at the branch point of the conveyor line. Background Technology

[0002] When using an assembly line to manufacture products, the products to be manufactured are usually composed of multiple components. Some products have a large number of components. To achieve batch production, a carrier conveyor line is usually required. The product components are loaded into carriers, and the carrier conveyor line transports the components to the corresponding processing positions to complete the various processing steps of the product. However, some product components have significant structural differences and are relatively fragmented, making them inconvenient to transport using ordinary carriers.

[0003] The conveyor line structure includes a main rail and several branch rails. Workstations are formed at the branch rail locations, where operators complete their respective tasks. The main rail transports the workpiece-carrying vehicles to each workstation. Sometimes, to enhance the conveyor line's functionality, other conveyor lines are connected to the main rail. Branch lines are formed between the main and branch rails, and at the junctions of different conveyor lines, to facilitate vehicle reversal. Swing arm mechanisms are installed at these branch lines to bridge the gaps and provide a path for the vehicles. Corresponding to the main and branch rail locations, independent power lines are provided along the conveyor line, powering the vehicles' movement on their respective tracks. During track changes, the vehicles are generally propelled alternately by the two power lines. Therefore, a continuous power supply to the vehicles cannot be guaranteed during track changes. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a support device for a conveyor line track switching switch, so as to realize the smooth track switching of the vehicle on the conveyor line.

[0005] To solve the aforementioned technical problem, the present invention provides the following technical solution: a conveyor line switch support device, used for installation at the switch position of the conveyor line, comprising a base plate, the base plate being horizontally arranged, and a drive wheel being rotatably mounted on the base plate. The device is characterized in that an upwardly extending bracket is provided on the base plate, the bracket having an opening for the drive belt to pass through; a swing arm is pivotally connected to the bracket via a pivot, and the swing arm is transmissionally connected to a drive mechanism on the bracket; in the vertical direction, the axes of the pivot and the drive wheel are close to or overlap.

[0006] The drive mechanism is typically a cylinder, which drives the swing arm to swing, thus bridging the corresponding gaps at the branch points. The drive wheel is usually a sprocket, and the drive belt is usually a chain. Several push blocks are installed on the chain. After the push blocks apply force to the load-bearing components on the vehicle, the vehicle gains propulsion. This support device, as an integrated unit, not only supports the corresponding power line but also provides support for the swing arm.

[0007] Furthermore, a mounting plate is connected to the bracket, and the mounting plate and the base plate are arranged parallel to each other. The swing arm is pivotally connected to the mounting plate, and the drive mechanism is mounted on the mounting plate. By setting up the mounting plate, the swing arm can be supported, which facilitates the stability of the swing arm during rotation, and also provides support for the swing arm, thereby facilitating the stable passage of the load-bearing vehicle.

[0008] Furthermore, the bracket includes a vertical plate, which is vertically positioned between the base plate and the mounting plate. The vertical plate facilitates the connection between the mounting plate and the base plate, resulting in a stable connection.

[0009] Furthermore, the upright plate consists of two pieces, with the opening located between the two upright plates. The two upright plates provide stable support for the mounting plate, facilitating the passage of the drive belt.

[0010] Furthermore, a protruding head is formed at one end of the mounting plate facing the upright plate, and a support portion is formed on one side of the upright plate facing the mounting plate; the protruding head extends between the two upright plates and is fixedly connected to them, while the support portion supports the back of the mounting plate. This type of upright plate can provide stable support for the mounting plate, resulting in good positional stability of the mounting plate.

[0011] Furthermore, a pad is provided on each side of the drive mechanism on the mounting plate, and a horizontally arranged upper plate is bridged on the two pads. The drive mechanism and the swing arm are located on the lower side of the upper plate. By raising the pads, a compact assembly space is provided for the drive mechanism and the swing arm, which facilitates the swing of the swing arm; on the other hand, the stability of the upper plate is also ensured.

[0012] Furthermore, the upper plate is vertically provided with two support plates, and a horizontally arranged top plate is bridged between the two support plates. The outer edges of the top plate and the upper plate protrude to the outside of the support plates, thereby forming a through groove with a C-shaped cross-section on the outside of the support plates. By forming a through groove on the outside of the support plates, when the load-bearing rollers on the vehicle pass through this support device, the outer edge of the top plate and the support plates can limit the movement of the load-bearing rollers, thereby effectively improving the positional stability of the vehicle during track changes.

[0013] Furthermore, the vertical plate and the base plate, the vertical plate and the mounting plate, the support plate and the upper plate, and the support plate and the top plate are all connected by a number of clips and slots. The use of these clips and slots effectively improves the connection strength between the corresponding components.

[0014] Compared with existing technologies, this utility model has the following advantages: This support device can provide support for part of the drive wheels on the power line, as well as for the power line and the swing arm. It has good overall integrity and facilitates the installation of the conveyor line. Because the support device can provide overall support for the corresponding mechanisms, the drive wheels and the swing arm can be positioned closer together, and the power line can provide maximum thrust when the vehicle changes track, which is beneficial for the smooth change of track.
