Abstract

A label wrapping device configured to warp a label around a cable includes a stripping part, a conveying roller, an insertion recess, a driving part and a controller. The conveying roller conveys the label peeled off a release paper by the stripping part in a conveying direction along a conveying path. The insertion recess is positioned downstream of the conveying roller in the conveying direction and is open toward the conveying path. The controller is configured to control the driving part: (a) to enable the conveying roller to convey the label peeled off the release paper in the conveying direction; and (b) to enable the conveying roller to halt conveyance of the label when an upstream end of the label becomes positioned downstream relative to the stripping part in the conveying direction and after the label covers at least a portion of an opening of the insertion recess.

First claim

What is claimed is:

1 . A label wrapping device configured to peel a label off a release paper of a label tape and wrap the label around a cable, the label tape being configured by a plurality of the labels sequentially affixed to the release paper, the label wrapping device comprising:
a stripping plate configured to peel the label one by one off the release paper; a conveying roller pair configured to convey the label peeled off the release paper by the stripping plate in a conveying direction along a conveying path, the conveying roller pair being positioned downstream of the stripping plate in the conveying direction, the conveying roller pair comprising:
a conveying roller; and
a follow roller facing the conveying roller in a direction crossing the conveying direction and configured to nip the label in cooperation with the conveying roller;
an insertion recess positioned downstream of the conveying roller pair in the conveying direction, the insertion recess having an opening that is open toward the conveying path for receiving the cable into the insertion recess through the opening; a driving motor configured to drive and rotate the conveying roller in the conveying roller pair; a one-way clutch interposed between the driving motor and the conveying roller in the conveying roller pair, the one-way clutch being configured to transmit a drive force of the driving motor to the conveying roller in the conveying roller pair; and a controller configured to control the driving motor, the controller being configured to perform:
(a) controlling the driving motor to enable the conveying roller pair to convey the label peeled off the release paper by the stripping plate in the conveying direction; and
(b) controlling the driving motor, after the (a) controlling, to enable the conveying roller pair to halt conveyance of the label when an upstream end of the label becomes positioned downstream relative to the stripping plate in the conveying direction and after the label covers at least a portion of the opening of the insertion recess,
wherein, in the (b) controlling, in a case where the conveying roller is urged to rotate while the driving motor is halted, the one-way clutch does not allow torque transfer between the conveying roller and the driving motor to enable the conveying roller to freely rotate following movement of the label in the conveying direction, and
wherein,
when the conveyance of the label is halted in the (b) controlling, the upstream end of the label is nipped by the conveying roller pair, and
when the cable is inserted into the insertion recess after the conveyance of the label is halted in the (b) controlling, the label is pulled downstream in the conveying direction by the cable to allow the upstream end of the label to be released from the conveying roller pair.

2 . The label wrapping device according to claim 1 , further comprising:
a plurality of gears mechanically connected to the driving motor to receive the drive force therefrom, wherein the one-way clutch is interposed between the plurality of gears and the conveying roller, the one-way clutch being configured to uncouple the driving motor from the conveying roller when the conveying roller rotates while the driving motor is halted.

3 . The label wrapping device according to claim 1 ,
wherein, in the (b) controlling, the controller is configured to control the driving motor to halt the conveyance of the label after a downstream end of the label reaches a position downstream of the opening of the insertion recess in the conveying direction.

4 . The label wrapping device according to claim 3 , further comprising a first restriction wall positioned downstream of the insertion recess in the conveying direction, the first restriction wall being configured to restrict the downstream end of the label from moving away from the conveying path in a prescribed direction crossing the conveying path.

5 . The label wrapping device according to claim 4 , further comprising a second restriction wall positioned downstream of the insertion recess in the conveying direction, the second restriction wall being positioned opposite the first restriction wall with respect to the conveying path in the prescribed direction and being configured to restrict the label from moving away from the conveying path and the first restriction wall in the prescribed direction.

6 . The label wrapping device according to claim 3 , further comprising a third restriction wall positioned downstream of the insertion recess in the conveying direction, the third restriction wall being configured to restrict the label from being conveyed further downstream in the conveying direction,
wherein, in the (b) controlling, the controller is configured to control the driving motor to halt the conveyance of the label after the downstream end of the label contacts the third restriction wall.

7 . The label wrapping device according to claim 1 , further comprising a release-paper conveying roller configured to convey the release paper to enable the stripping plate to peel the label off the release paper,
wherein the plurality of the labels comprises a first label and a second label affixed to the release paper, the second label being to be peeled off after the first label is peeled off, wherein the controller is further configured to perform: (c) controlling the release-paper conveying roller such that the release-paper conveying roller can peel a part of the second label off the release paper when the conveyance of the first label is halted in the (b) controlling.

8 . The label wrapping device according to claim 1 , further comprising a sensor positioned at the conveying path, the label having an upstream end and a downstream end in the conveying direction, the sensor being configured to detect at least one of the upstream end and the downstream end of the label conveyed in the conveying direction at the conveying path,
wherein, in the (b) controlling, the controller is configured to determine when to halt the conveyance of the label based on detection results from the sensor.

9 . The label wrapping device according to claim 1 ,
wherein the insertion recess is configured to receive the label together with the cable after an entirety of the label is peeled off the release paper by the stripping plate, the insertion recess being defined in a wrapping mechanism rotatable to wrap the label around the cable received in the insertion recess.

10 . The label wrapping device according to claim 1 ,
wherein a plurality of the conveying roller pairs is provided, the plurality of the conveying roller pairs being arrayed with one another at intervals in a direction perpendicular to the conveying direction across the conveying path.
