Abstract

The arrangement is used for dispensing individual reels of tape to a reel delivery system which loads and removes individual reels of tape from the tape testers and the tape winders in a tape manufacturing process. The reels are stacked 23 high as they come off the slitter, which is one of the machines used in the tape manufacturing process. The concept of dispensing reels at the tester and winder in the manufacturing process is identical. Accordingly, only the tape tester area reel dispensing will be considered. A stack of 23 reels is delivered to the indexing mechanism via an automatically guided vehicle 10, as shown in Fig. 1. On top of this vehicle is a fixture with two arbors (not shown) spaced 18 inches apart on the horizontal center line.

Reel-Dispensing Indexer Mechanism

The arrangement is used for dispensing individual reels of tape to a reel delivery system which loads and removes individual reels of tape from the tape testers and the tape winders in a tape manufacturing process. The reels are stacked 23 high as they come off the slitter, which is one of the machines used in the tape manufacturing process. The concept of dispensing reels at the tester and winder in the manufacturing process is identical. Accordingly, only the tape tester area reel dispensing will be considered. A stack of 23 reels is delivered to the indexing mechanism via an automatically guided vehicle 10, as shown in Fig.
1. On top of this vehicle is a fixture with two arbors (not shown) spaced 18 inches apart on the horizontal center line. The right-hand arbor is considered the supply arbor and is used for delivering untested reels of tape to the indexing mechanism. The left-hand arbor is for receiving tested reels from the indexing mechanism. The indexing mechanism has corresponding arbors 12 and 14 to match those on the automatically guided vehicle 10 fixture. It also has two locating shafts 16 which extend out to precisely position the automatically guided vehicle fixture so its arbors align with the two arbors 12 and 14 on the indexing mechanism. An air-actuated rotary clamp 18 is used to hold the arbor ends together while the stack of reels is being transferred from one arbor to the other. The purpose of using the two locating shafts 16 to align the arbors is to remove the plus or minus .25 inch stopping location tolerance of the automatically guided vehicle. The indexing mechanism has a motor-driven lead screw 19 with a push ring 21 attached to it which slides over the supply arbor 12 to index the stack of reels. The lead screw 19 is engaged and disengaged via an electric clutch 25, as shown in Fig. 2. Index advance is stopped by a pair of reflectance sensors 26 which sense the outer edge of the end reel. If one sensor 26 fails, the other prevents the drive from engaging. When the reels have been removed, the ring 21 advances until it is seen by one of the two sensors 26. A cutout was purposely added to the ring so only one sensor 26 can sense. This would automatically trigger the motor 28 to reverse at a high RPM to return the push ring 21 to its home position. A sensor 30 is positioned at the home po...
