Abstract
Abstract An automatic tape affixing apparatus for affixing a composite tape to an adhesion form includes a tape affixing head movable in X-axis, Y-axis, Z-axis, A-axis and C-axis directions, the tape affixing head carrying a tape supply reel, a tape take-up reel, a presser roller, a drive roller, a driven roller for pressing the tape against the drive roller, the driven roller being provided with a rotary encoder for detecting the rotation amount of the driven roller, and an auxiliary roller disposed on a take-out side of the drive roller for deflecting the tape closer to the drive roller than a tangent line at a contact point of the drive roller and the driven roller, so that the same shaped symmetrically formed on the take-in and take-out sides of a pressed contact portion of the drive roller and the driven roller, and detection of the feeding amount of tape is not consequently influenced by tape feeding direction alteration.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
265 words
An automatic tape affixing apparatus comprising a tape affixing head movable about a plurality of axes, said tape affixing head having a tape supply reel and a tape take-up reel, said tape moving along a tape path between said supply reel and said take-up reel, a presser roller disposed along said tape path, a drive roller and a plurality of driven rollers biased toward said drive roller and disposed along said tape path such that said tape passes between said drive roller and said driven rollers, said drive roller being made of a resilient material such that said biasing of said drive and driven rollers towards one another affects bulging of said resilient drive roller at a contact location where said drive roller contacts said driven rollers, said tape being in contact with said supply reel side of said drive roller juxtaposed to said contact location, a rotary encoder means on one of said driven rollers for detecting the amount of rotation of said one driven roller, an auxiliary roller disposed between said drive roller and take up reel, said plurality of driven rollers including an end roller, said auxilary roller being located so as to deflect said tape from said drive roller in a direction closer to said drive roller than a tangent line at the contact point of said drive roller and said end driven roller and the relative position of the tape to said drive roller and said end driven roller is the same on each side, whereby the amount of tape feed is accurately determined for each direction of tape feed.
Claim 2
Dependent Claim
265 words
An automatic tape affixing apparatus comprising a tape affixing head movable about a plurality of axes, said tape affixing head having a tape supply reel and a tape take-up reel, said tape moving along a tape path between said supply reel and said take-up reel, a presser roller disposed along said tape path, a drive roller and a plurality of driven rollers biased toward said drive roller and disposed along said tape path such that said tape passes between said drive roller and said driven rollers, said drive roller being made of a resilient material such that said biasing of said drive and driven rollers towards one another affects bulging of said resilient drive roller at a contact location where said drive roller contacts said driven rollers, said tape being in contact with said supply reel side of said drive roller juxtaposed to said contact location, a rotary encoder means on one of said driven rollers for detecting the amount of rotation of said one driven roller, an auxiliary roller disposed between said drive roller and take up reel, said plurality of driven rollers including an end roller, said auxilary roller being located so as to deflect said tape from said drive roller in a direction closer to said drive roller than a tangent line at the contact point of said drive roller and said end driven roller and the relative position of the tape to said drive roller and said end driven roller is the same on each side, whereby the amount of tape feed is accurately determined for each direction of tape feed.
Claim 3
Dependent Claim
18 words
An automatic tape affixing apparatus according to claim 1, wherein said driven roller is made of resilient material.
Claim 4
Dependent Claim
55 words
An automatic tape affixing apparatus according to claim 1, wherein said tape passes forwardly from said supply reel to said take-up reel for affixing a tape component to a surface by said presser roller, said tape being fed in a reverse direction to provide for placing an end of said tape at a desired position.
Claim 5
Dependent Claim
282 words
An automatic tape affixing apparatus comprising a tape affixing head movable about a plurality of axes, said tape affixing head having a tape supply reel and a tape take-up reel, said tape moving along a tape path between said supply reel and said take-up reel, a presser roller means disposed along said tape path, a drive roller means and a driven roller means biased toward one another and disposed along said tape path such that said tape passes between said drive roller means and said driven roller means, said drive roller means being made of a resilient material such that said biasing of said drive and driven roller means towards one another effects bulging of said resilient drive roller means at a contact location where said drive roller means contacts said driven roller means, said driven roller means comprising a plurality of driven rollers said tape being in contact with said supply reel side of said drive roller means juxtaposed to said contact location, a rotary encoder means on one of said driven rollers for detecting the amount of rotation of said driven roller means, one of said plurality of driven rollers being an end roller, an auxiliary roller disposed between said drive roller means and said take-up reel, said auxiliary roller being located so as to deflect said tape in a direction closer to said drive roller than a tangent line at the contact point of said drive roller and said end driven roller and the relative position of the tape to said drive roller and said end driven roller is the same on each side, whereby the amount of tape feed is accurately determined for each direction of tape feed.
Claim 6
Dependent Claim
282 words
An automatic tape affixing apparatus comprising a tape affixing head movable about a plurality of axes, said tape affixing head having a tape supply reel and a tape take-up reel, said tape moving along a tape path between said supply reel and said take-up reel, a presser roller means disposed along said tape path, a drive roller means and a driven roller means biased toward one another and disposed along said tape path such that said tape passes between said drive roller means and said driven roller means, said drive roller means being made of a resilient material such that said biasing of said drive and driven roller means towards one another effects bulging of said resilient drive roller means at a contact location where said drive roller means contacts said driven roller means, said driven roller means comprising a plurality of driven rollers said tape being in contact with said supply reel side of said drive roller means juxtaposed to said contact location, a rotary encoder means on one of said driven rollers for detecting the amount of rotation of said driven roller means, one of said plurality of driven rollers being an end roller, an auxiliary roller disposed between said drive roller means and said take-up reel, said auxiliary roller being located so as to deflect said tape in a direction closer to said drive roller than a tangent line at the contact point of said drive roller and said end driven roller and the relative position of the tape to said drive roller and said end driven roller is the same on each side, whereby the amount of tape feed is accurately determined for each direction of tape feed.
