Description

    The present invention relates to a label peeling machine, and more particularly, to a label peeling machine provided with a peeling unit for turning a backing of a label continuous body in which a plurality of label pieces are temporarily attached to a belt-like board and peeling the label pieces from the board. Is.

Conventionally, a label continuous body in which a plurality of label pieces are temporarily attached to a belt-like mount is loaded, and the label pieces are peeled one by one from the mount by pulling only the mount in the peeling portion. Label peeling machines are known. In general, predetermined information is printed on the label pieces in advance, and the peeled label pieces can be affixed to articles or products necessary for displaying various information.
This type of label peeling machine includes an automatic peeling method that removes the peeled label piece from the peeling portion, and the next label piece is automatically peeled off, and a peeling button or a peeling lever. There is a sequential peeling method in which the label pieces are peeled one by one when the peeling operation unit is operated.

In the case of the above automatic peeling type label peeling machine, the label piece that has been peeled off and not removed at the end of a day's work using the label peeling machine or when switching to a multi-label is necessary. However, there is a problem in that the label piece is useless as it may be an obstacle to the switching operation.
In other words, if this type of label peeling machine keeps feeding the label piece in its automatic mode, when the work is finished, the work must be finished with the last one piece of the label peeled off and fed out. Therefore, there is a problem that unnecessary label pieces are peeled off and one label piece is wasted.
Furthermore, if the label piece is left for a long time while being peeled off from the mount, the adhesive layer coated on the back side of the label piece dries and sticks to the required object. There is a problem that the function of may be lost.
Further, when the peeled label pieces are useless and the number of label pieces is managed, there is a problem that an error may occur in the management of the label pieces.
In addition, when a so-called peeling failure occurs, the label piece is transported with the label piece attached to the backing sheet that is turned in the peeling portion. In the case of simple operation, there is a problem of causing an error.

    In the case of the above-described sequential peeling type label peeling machine, the label piece is peeled off from the mount only when the peeling operation unit is operated, but other work is given priority when the label piece is peeled off. When it is necessary, if the label piece is left for a long time in a state where it is peeled off from the mount, the adhesive layer will be dried and attached to the required object as described above. Problems such as loss of the function of the printer, forgetting that the label piece has been peeled off, or for some reason the label piece has fallen off the peeling part, and therefore an error has occurred in the management of the label piece. There is a problem that can be.

    The position detection unit 5 includes a label sensor 16 and detects a gap between the label pieces 12 of the label continuum 2 or a position detection mark (not shown) preliminarily printed on the back surface of the label continuum 2. The relative position of the label continuous body 2 (label piece 12) with respect to the peeling part 6 is detected.

The peeling part 6 has a peeling plate 17 and a pressure plate 18, and can turn only the mount 11 of the label continuous body 2 at the tip turning part 17 </ b> A of the peeling plate 17 so as to be wound around the mount winding part 7. 12 can be peeled from the mount 11.
The pressure plate 18 assists and stabilizes the peeling action by pressing the label continuous body 2 from above toward the peeling plate 17.

    The mount winding unit 7 includes a winding roller 19 and a nip roller 20, and the mount 11 that is turned in the peeling unit 6 is sandwiched therebetween and wound into a roll.

The transfer roller 14 of the transfer unit 4 and the take-up roller 19 of the mount take-up unit 7 are rotationally driven by a drive motor 21 (for example, a step motor) so that they can be selected in the forward and reverse directions in synchronization with each other. .
More specifically, the transfer roller 14 of the transfer unit 4 moves the label continuous body 2 in the downstream direction in synchronization with the take-up roller 19 of the mount take-up unit 7 when peeling the label piece 12 from the mount 11. When the label continuous body 2 is transported by being able to be transported or by the winding roller 19 of the mount winding unit 7 winding the mount 11, the transport roller 14 itself can be freely rotated.
Further, when peeling the label piece 12 from the mount 11, the mount winding unit 7 can transfer the label continuous body 2 in the downstream direction in synchronization with the transfer unit 4, and the transfer roller 14 of the transfer unit 4. When the label continuous body 2 is reversely transferred upstream by rotating in the reverse direction, the take-up roller 19 itself can be freely rotated.

That is, in the label peeling machine 30, every time the peeling operation unit 31 is operated, the drive motor 21 is rotationally driven to transfer the label continuum 2 and turn the mount 11 at the peeling unit 6 to label the label. After stripping the strips 12 one by one and removing the stripped label strip 12, the stripping operation unit 31 is operated again to rotationally drive the drive motor 21 to transport and strip the next label strip.

The operation of the label peeling machine 30 having such a configuration will be described below.
That is, FIG. 4 is a flowchart of the operation of the label peeling machine 30, and in step S11, it is determined whether or not the operation signal is turned on by operating the peeling operation unit 31.
When the peeling operation unit 31 is turned on, the label continuum 2 is transferred in step S12, and the mount 11 is turned at the tip turning portion 17A of the peeling plate 17, so that the mount 11 is wound around the mount winding unit 7. Then, the label piece 12 is peeled off from the mount 11.
As shown in FIG. 3, the peeled label piece 12 is held by the tip turning portion 17 </ b> A in a temporarily attached state at its rear end portion.

    In the next step S13, it is determined whether or not the label piece 12 held by the tip turning portion 17A has been removed. This determination is made based on a detection signal from the peeling sensor 22 of the peeling detection unit 8.

When the label piece 12 is removed, the process returns to step S11 to determine whether the peeling operation unit 31 is turned on.
In step S13, if the label piece 12 is not yet removed, it is determined in step S14 whether a predetermined set time has elapsed. If not, the process returns to step S13 to remove the peeled label piece 12. Determine whether or not

In step S14, if the predetermined set time has elapsed, in step S15, the drive motor 21 is reversed, and in the transfer unit 4, the label continuous body 2 is reversely transferred upstream by the pitch of the label pieces 12 by the transfer unit 4. .
Therefore, since the peeled label piece 12 is returned to the upstream side by one pitch, the label piece 12 is put on the mount 11 again, that is, in a state before peeling. .

    Thus, even if the label strip 12 is peeled off by operating the stripping operation section 31, if there is no subsequent operation to remove the label strip 12, the label strip 12 peeled off at the stripping section 6 By returning to the state before peeling, various problems as in the past can be solved.
