Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for supplying mounts with self-labels attached to them in order to continuously supply self-labels to containers, packages, etc. that require labeling. This invention relates to a device for connecting mounts so that the adhesive surface of a self-label is always supplied to an adherend in the same direction without stopping.

[Prior Art] Conventionally used labels are pasted by sequentially peeling off self-labels from a mount to which they have been pasted, and then pasting them onto a container or package. In this type of labeling device, just before a roll of self-label roll is used up, the end of the self-label mount is connected to the leading end of the mount, on which a new self-label is pasted, or the starting end. The supply of self-labels was interrupted, and it was not possible to continuously apply labels to objects.

In other words, in order to peel off the self-label from the backing paper on which the self-label is attached in order to attach it to a container or package, the self-label is peeled off by folding back the backing paper on which the self-label is attached at an acute angle and pulling it back. Connecting the mounts is surprisingly difficult. This is because the peeling process of this label has the effect of peeling off the object stuck to the surface of the mount, so for example, if you stick it using an adhesive such as adhesive tape, this adhesive will peel off at the folding point, just like a self-label. It will peel off from the mount. The backing paper is usually peel-treated so that the self-label can be easily peeled off during use. As a result, the adhesive material also tends to peel off, making this an increasingly difficult problem.

Furthermore, since it is a self-label, the self-label from the new self-label roll that has been connected will be in the same state as the self-label from the previous roll, meaning that when it is peeled off from the backing paper, the adhesive surface will be the same on the object. They must be connected in such a way that they are supplied by the relationship. Therefore, the old and new mounts need to be connected in a specific relationship. Because of this difficult-to-solve problem, after using one roll of self-labeling roll, it is necessary to connect the starting end of the backing paper on which a new self-labeling roll is pasted to the labeling machine, and for this reason, the labeling Currently, we have no choice but to suspend the pasting work.

Although it is not a self-labeling device, Japanese Patent Application Laid-Open No. 15341/1983 discloses an apparatus that draws out a roll of tape, cuts it with a cutter, and supplies the tape. I see, with this device, it is shown that the starting end of a new roll of tape is connected to the ending end of the tape, but since this tape is not self-labeled, the backing paper with the self-label pasted at an acute angle is folded back and pulled back. As a result, peeling of the self-label is completely eliminated, so that the problem of the adhesive part peeling off at the folding point does not occur. Also, the old and new tapes do not need to be connected in any particular relationship.

In this way, the invention disclosed in Japanese Unexamined Patent Publication No. 15341/1980 has nothing to teach us about the problem of self-label mount connection that the present invention must solve.

[Problems Solved by the Invention] The present invention solves all of the above-mentioned problems of self-label mount connection. That is, just before the end of use of one roll of self-label roll, a new self-label is pasted to the end of the self-label mount, and the end of the mount, that is, the starting end, is stopped from applying the label to the object to be affixed. When the new and old mounts are connected without any problem, and the self-label is peeled off from the mount, the joint does not peel off, and the self-label from the connected new self-label roll is in exactly the same state as the self-label from the previous roll. The adhesive surface was successfully applied to the object to be adhered in the same manner when it was peeled off from the mount.

[Means for Solving the Problems] The present invention comprises: "A. An arm 17 rotatably supported by a rotating shaft 18, and a plurality of roll holders arranged on the arm 17 to which rolls on which label pasting sheets are wound are mounted. B. A suction hole 14b for suctioning and holding the tip of the opposite side to which the label is pasted of the replenishment label mount 2b to which the connecting adhesive is pasted, which is open to the pressurizing surface, and a pressurizing device 15 are provided. A joining device 14 consisting of a holding device 14a that has been pressed and a pressurizing pedestal 14c with which the label attachment surface of the preceding label mount 2a comes into contact; 6, 7, D Detection sensor 1 that detects the end of the label mount

Self-label mount connection device. ” related.

[Function] The present invention allows the label of the leading end, that is, the starting end, of the self-labeling paper of the next roll to be affixed to the surface to which the terminal label of the preceding self-labeling mount is not attached, that is, the back surface. By pasting the facing surface, the self-labeled backing paper is folded back at an acute angle and pulled back. When the self-label is peeled off, the adhesive part of the backing paper is folded back by the terminal part of the self-labeled backing paper that precedes the self-labeled backing paper. In addition to completely preventing the self-label from being pressed against the component and peeling off, the self-label from the connected new self-label roll remains in the same state as the self-label from the previous roll, so that when it is peeled off from the backing paper, it will not stick to the object. The adhesive surfaces could be supplied in the same relationship.

In order to connect the self-labeled backing paper to this relationship, connect the self-labeled backing paper of the next new roll to the tip of the self-labeled backing paper, that is, the end of the side where the starting end label is attached. A piece of material is placed in advance and held by a suction hole opened on the pressurizing surface of the liner holding device, and a signal from a detection sensor that detects the end of the preceding label liner causes the liner holding device to press down on the preceding label liner. The label pasting surface is pressed against the contact pressure holder and adhered to the back side of the preceding label mount, thereby connecting the old and new mounts. After the connection is completed, the roll switching device is operated to rotate the arm supported by the rotating shaft and change the position of the roll holder provided on the arm so that the supply position of the label mount roll is always the same. On the other hand, a new label mount roll is attached to the empty roll holder, set in the same manner, and kept on standby. In this way, the front surface of the next label mount can be adhesively connected to the back surface of the preceding label mount, and when it is peeled off from the mount, the adhesive surface can be supplied to the object to be affixed in the same relationship.

[Embodiment] FIG. 1 shows an embodiment of the self-label mount connecting device of the present invention. A preceding self-label mount 2a with a self-label 3 wound into a roll
is held by a roll holder 5 and sent out by a pair of feed rollers 6 and 7.As will be explained later, the self-label mount is held at an acute angle in the process of attaching a self-label to a container or package. It is folded back, the self-label is peeled off, and it is affixed to a container or package.

On the other hand, the front side of the front end of the new self-label mount 2b with the self-label 3 attached thereto is attached with a connecting adhesive such as adhesive tape, and is sucked into the suction hole 14b of the holding device 14a of the bonding device 14 and set. I'll keep it. In addition, the suction hole 14 of this joining device 14
Many holes are formed in b to hold the leading end of the new self-label mount 2b flat. Next, at the same time as the feed rollers 6 and 7 stop, the pressing device 14a of the bonding device 14 holds the leading end of the new, succeeding self-label mount 2b, and presses the preceding self-label using a pressure device 15 such as an air cylinder. After the label pasting surface of the mount 2a is pressed against and pressurized by the pressure holder 14c of the bonding device that is in contact with it, it returns to its original state. At the same time, the suction of the new succeeding self-label mount 2b is removed. In this way, the preceding self-label mount 2a
The leading end of the succeeding self-label mount 2b completes the connection to the back side of the terminal end, that is, the side to which the self-label 3 is not attached.

In addition, since the subsequent self-label holder 16 of the connected self-label mount 2b needs to be moved to the position of the preceding self-label holder 5 in order to connect the next new mount, the switching device 19
, it is moved to the position of the preceding self-label mount holder 5. The most suitable switching device is a rotary type that rotates the self-label mount holders 5 and 16 at opposite positions by 180 degrees around the rotation axis 18, but it is preferable to use a rotary type that switches the self-label mount holders 5 and 16 to opposite positions. They may be arranged and rotated sequentially.

After that, a new self-label mount 2 (not shown) is set in the position of the self-label mount holder 16 until the number of preceding mounts runs out, and
It is sufficient to attach a connecting adhesive to the front side of the tip and set it in the suction hole 14b of the bonding device 14.

As a result, the subsequent self-label mount 2b
can be set in the position of the self-label mount holder 16 without fail, and the self-label mount 2 that precedes
Back side of the end of a (unlabeled side)
The front side (labeled side) of the new self-label mount 2b can be connected to.

Furthermore, a storage section for self-label mounts may be provided in order to continuously perform the process of attaching self-labels to containers and packages even when the self-label mounts are connected. In FIG. 1 which is an embodiment of the present invention, when the preceding self-label mount 2a with the self-label 3 attached is sent out a little earlier than the self-label pasting work process speed, the guide rollers 8, 9
In the area B between the two, slack is generated and the self-label mount is stored. The slackness is detected by the slackness detection sensor 10, and the feed rollers 6 and 7 are stopped. Further, the slack in the portion B is reduced by the pulling of the self-label mount 2a moving in the direction A, and this reduced state is detected by the slack detection sensor 10, and the feed rollers 6 and 7 start rotating again. If such a mount storage section is provided, even if the feed rollers 6 and 7 are stopped when joining the mounts, there is no need to stop the process of attaching the self-label to the container or package.

Such operations are always repeated, and the self-label mounts 2a to which the self-labels 3 are attached are sequentially and continuously sent to the labeling device.

When the trailing edge detection sensor 13 detects that the trailing edge of the preceding self-label mount 2a has passed, the operation of the slack detection sensors 10 and 11 is stopped and the feed rollers 6 and 7 are moved regardless of the position of slack in the mount.
continues to rotate and supplies extra self-label mount 2a in advance of portion B. When the end portion passes the end portion detection sensor 13, the feed rollers 6 and 7 are stopped regardless of the slackness detection sensor 10.
At the same time as the connection of the self-label mount is completed, the slack detection sensors 10 and 11 resume operation, and the feed rollers 6 and 7 are operated according to the position of slack in the self-label mount 2a. It should be noted that during this connection, the preceding self-labeling paper 2a supplied in excess to the portion B is supplied to the self-labeling process, so there is no need to interrupt the self-labeling process.

When the connection of the self-label mount 2b is completed, the subsequent self-label mount holder 16 is switched to the switching device 19.
, it is moved to the position of the preceding self-label mount holder 5. At the same time as this position switching, the slack detection sensors 10 and 11 also start operating.

FIG. 2 shows a state in which a preceding self-label mount 2a and a following self-label mount 2b are connected according to the present invention.

Overlap the back side of the terminal end of the preceding self-label mount 2a (unlabeled side) and the front side (labeled side) of the following self-label mount 2b, and connect them with adhesive. As a result, as shown in FIG. 3, when passing through the acute-angled portion 1, the preceding self-label mount 2a passes with the leading edge of the following self-label mount 2b pressed down, so that the following self-label mount 2b may peel off. can be prevented. Note that pressure-sensitive adhesive tape, pressure-sensitive adhesive, etc. are suitable as the adhesive.

FIG. 4 shows the self-label being peeled off from the self-label mount. The self-label 3 is peeled off from the self-label mount 2 by folding back the self-label mount 2 at the acute corner 1 and pulling it back. It is understood that when the adhesive material 4 such as cellophane tape is used for connection, as shown in FIG. 5, the following self-label mount 2b and the adhesive material will peel off at the connected portion. In other words, the adhesive 4 is also peeled off at the acute corner 1 in the same way as the self-label. This is because the backing paper is originally subjected to a peeling treatment so that the self-label can be easily peeled off, and conventional techniques have not been able to prevent the adhesive from peeling off.

[Effects] As described above, the present invention prevents peeling of the bonded portion of the self-label mount during the self-labeling process.
Self-labels can always be co-supplied in the same state even when the mount is replaced with a new mount, and the next self-label mount can be set in advance to be fed in a connected manner, reducing connection time. Excellent effects are produced.
