Technical Field

The invention relates to the technical field of conveyor control, in particular to a switch combined application structure for split type skid conveying.

Background

The structure taking a skid as a conveying carrier is widely used in a logistics conveying line system, wherein the structure is most widely applied to welding workshops and coating workshops of automobile manufacturers, and is mainly applied to various storage, conveying and process line bodies of the welding workshops and the coating workshops. Has the following characteristics: the same type of skid conveying carrier can be used for realizing a stepping type and a continuous type conveying mode, and different conveying pitches of the skid can be realized according to different process requirements; the circulation of the skid carriers can be realized in a plurality of conveying line bodies; the high-speed conveying and accurate positioning of the skid can be realized; the empty skids can be stacked and stored, the length and the space of the empty skid storage line are reduced, and the cost is saved.

The mechanical structure of the skid is generally integrated, and a positioning pin device on the skid is used for positioning an object to be conveyed. However, depending on the plant layout or the specificity of the line routing structure or the production requirements, a skid of an integral mechanical structure may not be used. The mechanical structure of the skid needs to be adjusted according to the requirement, and the mechanical structure of the split type skid is generated, as shown in fig. 1, namely a split type skid 6 and a split type skid 7. The split type skid is conveyed in the following mode: the method comprises the following steps that a locking device is used for locking a split type skid 6 and a split type skid 7 on an object to be conveyed, so that the split type skid 6 and the split type skid 7 and the object to be conveyed form a whole body temporarily for conveying, after the object to be conveyed is conveyed to a transshipment station, an unlocking device is used for separating the split type skid 6 and the split type skid 7 from the object to be conveyed, the split type skid 6 and the split type skid 7 are continuously conveyed to an upper work station according to process requirements, and next circulation is carried out; or the split type skid 6 and the split type skid 7 are conveyed to a designated station and separated from the line body to be carried manually.

According to the mechanical structure of the split type skid, different problems exist between the conveying stage of the empty skid and the integral skid. The mechanical structure of the split type skid limits that the split type skid 6 and the split type skid 7 must be separately conveyed, and the split type skid 6 and the split type skid 7 are conveyed on the same rolling bed in synchronization theoretically, such as the relative position relationship shown in fig. 1; in fact, according to the difference in manufacturing, the difference in oil contamination during the use of the split skid, the difference in manufacturing of the roller bed rollers, and the difference in various mechanical resistances, the friction coefficients of the respective transportation of the split skid 6 and the split skid 7 are inevitably different, and due to the above reasons, the asynchronization of the transportation of the split skid 6 and the split skid 7 is inevitably caused. When the split type skids 6 and 7 are not conveyed synchronously, the front skids and the rear skids are impacted to damage the skids and equipment.
