A light emitting unit 27a and a light receiving unit 27b are provided on one side and the other side of the upper frame 25a. When the object to be transported stops at a set position inside the first inspection unit 20a, the third The detection sensors 27a and 27b detect whether there is a portion protruding from the upper portion of the object to be transferred to the set position. In this case, the third detection sensors 27a and 27b may be made of a light curtain to detect the entire upper region of the first inspection unit 20a.

In the above, the case where the object to be detected is detected by the first detection sensor while the object to be transported is described has been described, but both sides of the object to be transported are projected by the first sensor when the object is stopped at a certain position. Sensing, the front and rear of the object to be transported are detected by the second sensing sensor, and the upper side of the object to be transported can be detected by the third sensing sensor. In this case, in order to minimize undetected areas, it is preferable that all of the first to third sensing sensors are made of light curtains.

As described above, preferred embodiments of the present invention have been described in detail, but the present invention is not limited to the above-described embodiments, but is modified in various ways within the scope of the claims and detailed description of the invention and the accompanying drawings. It is possible to carry out and this also belongs to the present invention.
