Description

  The present invention relates to a hanger used in a trolley conveyor for transporting an object to be transported such as an automobile body, and more specifically, to cooperate with the trolley conveyor in a hanging rod body in a suspended state. In addition, the present invention relates to a transfer / transport hanger for transferring and transferring between a plurality of trolley conveyors in cooperation with a transfer unit.

Conventionally, as a transfer hanger of this type, a plate-like member having a large number of holes in the transverse direction is fixed to the circumferential surface of the rod-like body along the longitudinal direction of the rod-like body. There is a configuration in which the upper end of a character-shaped hanger is hooked and the lower end is hooked on an object to be conveyed (see Patent Document 1).
Japanese Laid-Open Patent Publication No. 58-17010 (first page, FIG. 1)

However, in the conventional hanger disclosed in Patent Document 1 described above, an object to be transported having a long shape in the transport direction is suspended at two points in the transport direction by using two C-shaped suspensions. In addition, since the two hooks are hung on the conveyor using a pair of hooks, there is a troublesome problem that the transfer mechanism becomes complicated and the handling becomes troublesome.
In addition, when transporting a long transport object, it is forced to a transport posture along the transport direction, so that there is a problem that a large restriction is imposed on the transport object size and transport interval on the transport line. .

Furthermore, with conventional hangers, the trolley conveyor must be stopped and transferred when transferring the object to be transferred, and intermittent transfer of the object to be transferred is forced. There was a troublesome problem in the transfer work that the transfer operation could not be realized and the transfer time could not be shortened.
In addition, since the transfer method is adopted in which the object to be transferred is removed in the direction perpendicular to the transfer direction, the transfer timing shifts with respect to the hanger, and the transfer space between multiple trolley conveyors increases. There was a troublesome installation space problem that had to be secured.

  Therefore, the problem to be solved by the present invention, that is, the object of the present invention is to solve the problems of the prior art as described above, and the dimensions, transport interval, and transport of the object to be transported on the transport line. Provide a transfer transport hanger that achieves a quick and smooth transfer operation at a reliable transfer timing with a flexible attitude and achieves space saving and a simplified conveyor mechanism between multiple trolley conveyors That is.
