Abstract

PROBLEM TO BE SOLVED: To provide a sleeve feeder which is capable of efficiently feeding sleeves different in length as well as those identical and which is also easy to be automatized, in a production line for many kinds in small quantities. SOLUTION: Sleeves 13-16 on an inclined placing face are centered one by one successively, thereby enabling them to be dispensed using the same sleeve feeder A even if the sleeves 13-16 are different in length. In addition, in the case where the sleeves 13-16 transferred to the feeder A by a hanging means 18 are shifted to the front and the rear and not in parallel, they are easily corrected for the parallel by a sleeve correcting stopper 17, which enables the centering to be performed easily and surely thereafter.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sleeve feeder used for inserting a sleeve as a core material into a coil in a continuous annealing line, a tin plating line, or the like.

[0002]

2. Description of the Related Art In the above-mentioned line, when a thin plate is wound into a coil, an iron or paper sleeve is inserted in order to prevent deformation of the inner diameter of the coil. Here, the length of the sleeve uses the coil width plus about 30 mm, but since the coil width changes for each coil, various types of sleeves having different lengths are used for each coil to be passed. doing.

Conventionally, in the above-mentioned various lines, coils having the same width are collected and passed in consideration of production efficiency. Therefore, the same type of sleeve is stocked in the sleeve feeder used to supply the sleeve to the coil car, and the centering is performed using a predetermined centering mechanism.

[0004]

However, the above-mentioned sleeve feeder still has the following problems to be solved. That is, as described above, there is no problem when passing coils having the same width, but when changing coils having different widths for each plate, one sleeve corresponding to each coil is supplied, and After performing the centering, the sleeve is mounted on a winder, and this operation is repeated every time the coil width is different. At present, a small number of workers monitor the wound coil, pay out the coil,
When the winding operation is being prepared and the above-described supplying operation is added, the workability is significantly reduced, and the production amount may not be secured. In addition, since there is no sleeve stock in the sleeve feeder, manual intervention increases, which impedes automation.

[0005] The present invention has been made in view of such circumstances, and in a production line of a small amount and various kinds, not only sleeves having the same length but also sleeves having different lengths can be efficiently supplied. Another object of the present invention is to provide a sleeve feeder that can be easily automated.
