JPS6413351A - Detecting device for winding tape end - Google Patents

Abstract

PURPOSE:To automatically detect a winding tape end by providing an intake means to give intake action to the suction port of a holder provided near the outer peripheral surface of a tape to be rotated, and providing a sensor which detects pressure variation in an intake chamber of the holder to stop the rotation of a table rotating means. CONSTITUTION:When a motor 8 is driven to rotate a winding tape end 1a of a tape 1, and the end 1 is thereby made to approach a suction port 18 of an intake chamber in a holder 17, the winding tape end 1a is sucked to the suction port 18. As a result of this suction, air pressure in the intake chamber of the holder 17 rises, and a pressure sensor 20 detects the above-mentioned pressure variation through a hose 19. The detection signal stops the rotation of a motor 8, and makes the cylinder 21 function to cause its pushing pressure piece 22 to press the winding tape end 1a against the suction port 18. Next, the function of a cylinder 13 rotates a holder 17 and a rotary arm 14 through a slider 10 against the force of a spring 16 to draw the tape 1 as long as a fixed length, and then a core 6 held by the slider 10 is stuck on the tape.
