Patent ID: 8646508

Claim:
A label peeling machine configured to peel adhesive labels of a non-liner label web one by one, wherein the non-liner label web has a number of the adhesive labels stuck continuously so as to be overlapped while being shifted by a predetermined distance respectively, said label peeling machine comprising: a reel configured to wind and hold the non-liner label web; a carrier belt configured to transport the non-liner label web in forward and backward motions along a carrier belt path including a first path portion extending in a first direction and a second path portion extending in a second direction generally perpendicular to said first direction; a rotatable drive shaft operably coupled with said carrier belt so that said carrier belt is driven when said drive shaft is rotated; a drive motor configured to rotate the drive shaft to drive the carrier belt; a switch configured to cause operation of the drive motor to rotate the drive shaft; a first driven shaft configured to receive transmission of rotation of the drive shaft via a transmitting mechanism; a second driven shaft and a third driven shaft configured to receive transmission of rotation of the first driven shaft via the carrier belt; a first press roller configured to press, in the first direction, the non-liner label web as the non-liner label web moves in the second direction along the second path portion of the carrier belt path; a second press roller configured to press, in the second direction, the non-liner label web as the non-liner label web moves in the first direction along the first path portion of the carrier belt path; a first sensor configured to perform a first detection when the non-liner label web has moved in the forward motion along the first path portion of the carrier belt path to reach a first predetermined location, and to issue an operation signal to indicate said first direction; a second sensor configured to perform a second detection when the non-liner label web has moved in the backward motion along the first path portion of the carrier belt path to reach a second predetermined location, and to issue a stop signal to indicate said second detection; a peeling claw configured to engage the non-liner label web moving upward along the carrier belt and peel the adhesive labels one by one; and a control device operably coupled to the drive motor, the switch, the first sensor, and the second sensor to reverse operation of the drive motor to cause movement of the non-liner label web in the backward motion when the first sensor issues the operation signal, and to stop operation of the drive motor to stop movement of the non-liner label web when the second sensor issues the stop signal.
