[0002] In tire production, the picking section of the tread production line of the tire factory is to place the treads from the production line onto the tooling shutter car. The treads are placed manually or mechanically. The treads on the production line are taken down and then placed onto the blades of the shutter car. After the shutter car is full of treads, the blades are turned over and continued to be placed until the entire shutter car is full.

[0003] The Chinese patent document publication number is CN208008043U, and the patent name is: "Tread Picking Device", which includes a frame one and a frame two, wherein the frame one has an adsorption mechanism for grabbing the tread, and the frame two has a conveying rail, and the conveying rail has a conveying plate for placing the tread, and the conveying rail includes a horizontal conveying section and an inclined flipping section. The adsorption mechanism can adsorb the tread and place the adsorbed tread on the conveying plate of the conveying section. After the conveying plate moves to the flipping section, the tread located thereon can flip under the action of gravity and detach from the conveying plate. The device uses an inclined flipping section, and requires the device to be built higher, which is prone to safety hazards.
