Abstract

PURPOSE:To stably perform parts supply stably rewinding a coating tape by changing force, in which the coating tape peeling off from an electronic part storage tape is rewound to a reel, in accordance with a tape width different by a size of an electronic part. CONSTITUTION:When a sucker nozzle 4 comes to a sucking position by moving a part supplier 3, depressing a roller 64 by a release bar 63 separating a pressing piece 61 from a tape reel 13, it is placed in a turnable state. While a vertical operation mechanism 58 lowers a vertically moving member 57, turning a supporting member 44 or 45. The supporting members 44, 45 are selected in accordance with a tape width different by a size of parts stored in a tape 21. For instance, when the storage tape is 8mm in width, a roller 49 is pressed by a spring 55 onto a friction ring unit 38 of a rewinding reel 37. When the tape is 12mm in width, a separate roller is pressed by a different spring onto the friction ring unit 38. Thus controlling force of the coating tape rewinding reel 37 in accordance with a size of the part, the coating tape is stably rewound.

The film must be peeled off before being rolled up.

Similarly, storage tape c! When the tape width D is 12M or more, as shown in FIG. 6, for example, if it is 12 steps, the position of the friction ring body (end) of the take-up reel Gη will be the position indicated by the two-dot chain line. For this reason, while applying a pressing force from the spring (54) Ic corresponding to the force of the take-up reel S that stores the storage tape round of 12 tape width, the take-up reel G7 is
) It is possible to wind up the tape by rotating it completely and peeling off the cover tape.
