Parallel turnover mechanism for picking up treads

Abstract

The utility model relates to a parallel turnover mechanism for picking up treads. According to the technical scheme, a transmission shaft and a fixed chain wheel are installed in the middle of a middle connecting arm, a first chain wheel and a second chain wheel are installed at the two ends of the middle connecting arm in a distributed mode, and the first chain wheel and the second chain wheel are connected with the fixed chain wheel in a meshed mode through chains. A second lifting support is installed on the outer side of the second chain wheel. The lifting device has the advantages that when the transmission shaft in the middle rotates, the first chain wheel and the second chain wheel at the two ends are always kept opposite to the fixed chain wheel in the middle under the action of the chain, and the first lifting support and the second lifting support are always kept horizontal; therefore, the treads are overturned to the storage mechanism from the roller bed mechanism; in addition, the upper surfaces of the first lifting bracket and the second lifting bracket are of other planar irregular structures, so that the treads can be overturned from the roller bed mechanism to the storage mechanism.

Description

Technical Field

[0001] The utility model relates to the technical field of tread picking equipment, in particular to a parallel turning mechanism for tread picking. Background Art

[0002] The picking section of a tire factory's tread production line places treads from the production line onto a trolley. Before automation, this process was manual. Two workers took turns removing treads from the production line and placing them onto the trolley's blades. Once the trolley was full, they would manually flip the blades and continue placing treads. This process involved many workers, and manual placement of treads was prone to stretching and sticking, resulting in uneven placement and unreliable quality. Furthermore, manual operation was labor-intensive and had a low safety margin.

[0003] Another company in the same team has applied for Chinese patent number 2022207159945, entitled "Novel Tread Picking Device." The device features a storage mechanism and a conveyor mechanism mounted on a chassis. A lifting platform is located at the front of the conveyor mechanism, and a louvered cart is positioned outside the conveyor mechanism. A roller bed mechanism is mounted above the storage mechanism, with conveyor rollers distributed across the roller bed mechanism. A flipping mechanism is provided with flipping rods, and multiple sets of vacuum suction cups are positioned on the top surfaces of the flipping rods. The flipping rods are staggered between the conveyor rollers. The flipping mechanism in this utility model deposits the tread onto the storage mechanism. The tread is then transported from the storage mechanism to the conveyor mechanism, where a conveyor belt drives the conveyor mechanism toward the louvered cart, placing the tread onto the louvered cart. The puller mechanism, louvered cart, and pusher mechanism are aligned, creating a compact footprint. This allows for mechanized tread pickup and flipping, reducing worker workload. While the flipping mechanism in this patent utilizes vacuum suction cups to hold the tread, this utility model employs a different mechanism to achieve tread flipping. Utility Model Content
