TECHNICAL FIELD

[0002] The flow line is used for realizing the preparation of products, and the structure of the flow line comprises a ring track, a flexible driving mechanism is arranged to adapt to the running direction of the ring track, a plurality of workstations are arranged on the running direction of the ring track, work positions are formed at the positions of the workstations, and an operator performs the preparation of corresponding procedures of products at the work positions. A large number of carriers need to be arranged on the flow line, under the action of the driving mechanism, the carriers carry product components, and the product components are transported to corresponding work positions so that the operator can assemble the product components. In order to ensure the continuity of the operation work and improve the work efficiency, the carrier redundancy setting mode is usually adopted, that is, each operator corresponds to a plurality of carriers. The carriers are arranged at the drop waiting positions, and the drop mechanism at the downstream realizes the drop so that the operator can process the product components on the carriers. Since the structure of the carrier is not too compact, and the product components loaded sometimes also protrude outward, such as cloth hung by a hanger, the carriers have a certain entanglement at the drop waiting positions, and when the carriers are dropped, a plurality of carriers may travel together, so that several carriers may accumulate together at the processing waiting position, which brings certain trouble to the subsequent processing of the operator, and this affects the work efficiency.

[0022] With reference to the accompanying drawings, the pipeline carrier separation limiting device is arranged on the pipeline, and is used for separating and limiting the carriers waiting on the pipeline. When the carriers are lowered, the subsequent carriers cannot be lowered at the current time. Of course, the separation limiting device can also be used as a simple lowering mechanism to lower the carriers on the lowering waiting position.

[0023] The pipeline includes a track, which can be arranged on a branch of the pipeline or on a workstation. A passage is formed on the periphery of the track for the upper hanging part of the carrier to pass through, and the passage is formed by the running track of the hanging part on the track. The separation limiting device is arranged on the outer side of the track, and the structure includes a fixed seat 6, and the fixed seat 6 is provided with a power structure. As shown in the figure, the power structure is a cylinder 1. A limiting piece 4 is movably arranged on the fixed seat 6, and the main part of the limiting piece 4 is a rod-shaped body. The limiting piece 4 is horizontally arranged, and a concave body or a convex head is formed at the inner end of the limiting piece 4 for connecting with the piston rod in the cylinder 1. These concave bodies or convex heads are part of the transmission structure, and the transmission connection between the piston rod in the cylinder 1 and the limiting piece 4 is realized. Under the action of the cylinder 1, the limiting piece 4 is used to extend into the passage or separate from the passage.

[0024] The fixed seat 6 is provided with an extension 62 extending towards the track, and an opening 61 is formed in the extension 62, through which the channel passes. When the cylinder 1 is driven to separate and limit the carriers, the extension end of the limiting member 4 extends into the opening 61, and the carriers are generally limited at the position of the opening 61. When the limiting member 4 is separated from the channel, the carriers can move forward. When the present separating and limiting device is used in cooperation with the lowering mechanism, the carriers blocked by the limiting member 4 are blocked by the lowering mechanism, and then the limiting member 4 extends into the channel again to separate and limit the carriers arranged at the lowering waiting position. The distance between the limiting member 4 and the lowering mechanism corresponds to the transverse size of the hanging part on the carriers, and the limiting member 4 generally separates one carrier at the lowering mechanism each time, that is, the limiting member 4 extends into the interval between the hanging part of the carrier and the hanging part of the adjacent carrier, so as to block the remaining carriers on the upstream side. After the lowering mechanism lowers the carriers, the limiting member 4 is separated from the channel to release one carrier at the position of the lowering mechanism to wait for lowering. The power structure and the lowering mechanism can be in a sequential action relationship, that is, after the lowering mechanism is reset after lowering the carriers, the power structure is started to make the limiting member 4 retract and extend.
