Description

The present invention relates to an article processing apparatus suitable for use in assembling articles, particularly two kinds of articles having different left and right sides, such as a vehicle sun visor.
In the present invention, “processing” includes various processing such as turning and grinding of an article, processing such as pressing, molding, or assembly.

  Generally, a sun visor for a vehicle includes a right-handed one and a left-handed one. For example, one for a driver seat and one for a passenger seat, or one for a right handle and a left handle. When assembling such a mishanded sun visor, a right-handed assembling device (processing device) and a left-handed assembling device are conventionally arranged adjacent to each other on the left and right. Each time an incorrect sun visor flows through the processing line, the worker moves to the corresponding assembly device, and each of the assembly devices is assembled with an incorrect sun visor.

  In addition, said prior art is a conventional technique and is not based on a specific prior art document.

  When two assembling apparatuses are installed, there is a problem in that the work efficiency is lowered because an operator has to move between the two assembling apparatuses every time the visor to be assembled changes.

In order to solve the above problem, the present invention is provided so as to be rotatable between a first position and a second position around a base frame and a rotation axis extending in the vertical direction on the base frame. A rotating frame, a first processing portion provided in a portion of the rotating frame that is positioned on the front side when positioned at the first position, and the second position of the rotating frame. And a second processing portion provided in a portion positioned on the front side when positioned at the position.
In this case, it is preferable that the first position and the second position are arranged 180 degrees apart from each other in the circumferential direction around the rotation axis.
Further, the first and second processing parts may be first and second assembling parts for assembling articles having the opposite sides.

  For example, in the case of assembling a left-handed sun visor and a right-handed sun visor according to the present invention having the above-described characteristic configuration, when the left-handed sun visor flows on the processing line, the rotating frame is moved to the first position. And assemble a left-handed sun visor at the first processing section. When the right-handed sun visor flows, the turning frame is turned to the second position, and the right-handed sun visor is assembled at the second processing portion. Thus, when assembling two types of sun visors having different abilities, it is only necessary to rotate the rotating frame between the first position and the second position, and there is no need for the operator to move. . Therefore, work efficiency can be improved.
