Abstract
This invention provides a tape extracting unit having an excellent performance and a compact small structure, the tape extracting unit comprising: two pairs of first and second extracting roller units whose rotation velocities are capable of being adjusted separately; guide frame which is disposed between the first and second extracting roller units and forms an expanding space for storing a tape; and a sensor for detecting the storage condition of the tape within the guide frame electrically, wherein the tape pulled out of the roll body is stored within the expanding space of the guide frame as a storage tape to which no tension is applied; and the rotations of the first and second extracting roller units are controlled based on a detection signal of the sensor so as to be able to extract the storage tape.
Claims6
A tape extracting unit disposed at a position in the vicinity of a rotation table loaded with a roll body, comprising:
- two pairs of first and second extracting roller units whose rotation velocities are capable of being adjusted separately;
- a guide frame which is disposed between the first and second extracting roller units and forms an expanding space for storing a tape;
- and
- a sensor for detecting the storage condition of the tape within the guide frame electrically, wherein the tape pulled out of the roll body is passed through the first extracting roller unit, guide frame and second extracting roller unit in succession and disposed;
- the tape to which no tension is applied is stored within the expanding space of the guide frame as a storage tape;
- and
- the rotations of the first and second extracting roller units are controlled based on a detection signal of the sensor so as to be able to extract the storage tape.
A tape extracting unit disposed at a position in the vicinity of a rotation table loaded with a roll body, comprising:
- two pairs of first and second extracting roller units whose rotation velocities are capable of being adjusted separately;
- an auxiliary feed conveyer which is disposed between the first and second extracting roller units and rotates in a single direction from the first extracting roller unit to the second extracting roller unit;
- a guide frame which is disposed on the auxiliary feed conveyer and forms an expanding space for storing a tape;
- a sensor for detecting the storage condition of the tape within the guide frame electrically;
- and
- a control unit for controlling the rotations of the first and second extracting roller units separately based on a detection signal from the sensor, wherein
- the tape pulled out of the roll body is passed through the first extracting roller unit, guide frame on the auxiliary feed conveyer and second extracting roller unit in succession and disposed;
- and
- the control unit controls the rotations of the first and second extracting roller units separately based on a detection signal from the sensor so as to store a tape to which no tension is applied with the expanding space within the guide frame as a storage tape so that the storage tape is capable of being extracted.
