Title: Carrying control method
Inventor: YOSHITAKE MAKOTO
IPC: G05D1/02
Filed: 1991-08-12
Abstract: PURPOSE:To prevent congestion of carriers by arranging position sensors for detecting passage of carrier at the inlet and outlet of each zone provided with a stator and arranging a speed sensor in front of the stator thereby detecting presence of the carrier in a downstream zone. CONSTITUTION:Position sensors arranged at the inlet and outlet of each zone provided with a stator detect entrance and departure of a carrier whereas a speed sensor arranged in front of the stator detects speed of the carrier. When a decision is made that the downstream zone is empty based on outputs from the position sensors and the speed sensor at decision step 24, stator in that zone is subjected to positive phase excitation 25 and advanced to the downstream. When the downstream zone is not empty, the speed of the carrier in that zone is detected 26 and if thus detected speed is not zero, stator in that zone is subjected to reverse phase excitation 27 and stopped. Control is then returned to step 24 where presence or absence of carrier in the downstream zone is decided again. According to the invention, congestion of carriers in each zone is eliminated resulting in enhancement of carrying efficiency.

Abstract: PROBLEM TO BE SOLVED: To eliminate skew and jam by furnishing a moving arm elevating/ sinking means and a push-out means which are capable of being operated individually, eliminating left-right dislocation of supporting arms. and making sure the biting by feed rolls. SOLUTION: A moving arm 5 equipped with a suction cup 4 is installed on supporting arms 7 and together therewith elevates and sinks through the action of a cam 11. Because the left and right supporting arms 7 are formed in a single piece, they are free from risk of dislocation to the left or right. When a film F is attached by suction, the cam 11 is rotated by a motor from the lower limit position to the upper, and the supporting arms 7 are lifted. When the moving arm 5 rises to reach the upper limit, a lever 16 rotates in the condition that the cam 11 is held at the upper limit level, and comes in contact with a guide pin 5d to be engaged thereby to generate forward pushing and advancing.  Accordingly the moving arm 5 is pushed forward against the energizing force of a spring 10, and the film F attracted by the suction cup 4 is pushed out to the position to be bitten by feed rolls 17, 18. Thus the film feed is started.
