Abstract

PROBLEM TO BE SOLVED: To simplify the structure and operation for coping with changes in the width and height of an article to be carried and cope with also a case in which the carrying direction is curved. SOLUTION: In this guiding device, a second guide surface 6 of a second guide member 7 is arranged so as to be opposed with space in the width direction of the carrier surface 2 on the first guide surface 3 of a first guide member 4 which is supported so that it may be reciprocated above a carrier surface 2. The space of the first guide surface 3 and the second guide surface 6 is gradually increased as the guide surfaces 3 and 6 approach the carrier surface 2. An area surrounded by the carrier surface 2, the first guide surface 3 and the second guide surface 6 is made a carrier path of an article C. In this case, the width and height of the article C which can be arranged in the carrier path are reduced by one direction moving of the first guide member 4 and are increased by the other direction moving of the member 4.

In the second portion 104b of the conventional guide device 104, when the caps C having different widths and heights are transported, the second portion 104b itself is replaced. This is because the radius of curvature of the inner circumference of the outer guide member 121a and the outer circumference of the inner guide member 121b are constant, so that when the guide members 121a and 121b are moved in the width direction of the conveying surface 112, Members 121a, 12
This is because the inner and outer peripheral surfaces of 1b cannot follow the transport path, and the cap C cannot be guided in a predetermined direction. Therefore, the number of parts increases, and a troublesome replacement operation is required.

An object of the present invention is to provide a device for guiding a conveyed article which can solve the above-mentioned problem.
