Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is connected to the end side of an upright conveyor that conveys roof tiles in an upright state, and the front and back sides of the roof tiles on the end side are turned over and transferred onto another connected upright conveyor. This invention relates to a counter-transfer loading device for accurately transferring roof tiles.

0002

[Prior Art] Conventionally, an upright holder consisting of a support rod protruding in the shape of a fork has been attached to an endless chain or the like that is circulated by a conveyor so as to face the front or back side of both sides of the roof tile. For tiles conveyed by an upright conveyor, at the start end of the upright conveyor, for example, if the tiles are conveyed in a collapsed state with the surface side facing upward, the posture is changed to an upright state, and then the posture is changed to an upright state at the end side. By converting the posture from an upright state to a collapsed state with the surface side facing downward, in order to make the posture of the tiles carried into the starting end of the upright conveyor the same as the posture of the tiles carried out from the terminal end,
In addition to arranging similar upright conveyors in a straight line, it is necessary to arrange an intermediate conveyor for transferring and conveying roof tiles in a lying position in order to prevent the support rods of the standing holders from interfering between the front and rear upright conveyors. As a result, the equipment becomes large and requires a large amount of installation space, and equipment costs rise. It had the disadvantage that it could not be accurately transferred onto the lodging conveyor.
