Description
Technical Field
[0001] The utility model relates to the technical field of workpiece transportation in a production line, in particular to a sling type transfer trolley and an RGV overhead rail conveying system. Background Art
[0002] As shown in the existing side-rolling chain conveying line system for sanitary ceramic green bodies Figure 1 This conveying system mainly includes: a lifting return plate machine, a double-layer side-rolling chain conveying line, a lifting transfer machine, and a stopper. The working process of this conveying system is as follows: The empty tooling plate is lifted by the lifting transfer machine from the lower layer of the double-layer side-rolling chain conveying line and conveyed to the lifting return plate machine, and then lifted and conveyed into the forming workstation by the lifting return plate machine; after the ceramic green body completes the processes of turning over and changing the plate in the forming workstation, it is first conveyed onto the lifting return plate machine, and then transferred by the lifting transfer machine on the upper layer of the side-rolling chain line body to the upper layer of the double-layer side-rolling chain conveying line, and then conveyed to the subsequent conveying system by the double-layer side-rolling chain conveying line, and so on in a cycle.
[0003] The above side-rolling chain conveying line system has the following problems: The existing conveying system layout is staggered and reciprocating, occupying a large area and affecting ground traffic; after the overall layout, there are certain limitations in later maintenance and transformation; the existing conveying system contains more equipment and more power, and the manufacturing cost is relatively high; the existing conveying system has a relatively high power consumption. The entire conveying system is composed of multiple double-layer conveying lines connected end to end. Each line is equipped with 1 power separately for the upper and lower layers, and auxiliary mechanisms such as lifting transfer machines and stoppers are required at the connection positions, with a high total power, consuming both electricity and gas; the existing conveying system uses side-rolling chain conveying. In actual work, the side-rolling chain conveying line is always powered on and running. When the tooling plate is conveyed on the side-rolling chain and is blocked by the stopper, the side-rolling chain continues to run forward, and the rollers on it rotate under the reaction force because the tooling plate remains in place. The inner ring of the roller and the shaft are in sliding friction, and there is also friction between the outer ring of the roller and the tooling plate. The side-rolling chain and the tooling plate are easily worn. After the side-rolling chain is worn, it needs to be replaced, and the maintenance frequency is relatively high during the actual production process. Summary of the Utility Model

[0040] The RGV cart 100 travels back and forth between the forming workstation and the subsequent conveying system. It defaults to docking at the board-taking position of the subsequent conveying system and waiting. When a workstation calls for blank taking, the RGV cart 100 uses the hoisting mechanism 200 to lower the clamping mechanism 300 to the board-taking height, grabs an empty tooling board 600 from the board-taking position, raises it to the conveying state and goes to that station. After arriving at the station, it first descends to place the empty tooling board 600 on the conveying blank rack. After placing the board, it then grabs the tooling board 600 loaded with ceramic green blanks from the blank-receiving rack, and conveys it to the blank-unloading position of the subsequent conveying system to complete blank unloading. After completing blank unloading, the RGV cart 100 takes another empty tooling board 600 from the board-taking position and returns to zero for waiting, and so on in a cycle.
