Description

  The present invention relates to a label sticking device for a cigarette package having a transparent outer packaging material and a sticking method thereof.

Since this kind of cigarette package is provided with a transparent outer packaging material, individual cigarette packs in the cigarette packaging body can be visually recognized from the outside through the transparent outer packaging material. For this reason, there is a problem that an identifier given to each cigarette pack, that is, a so-called bar code is erroneously read. In order to solve such a problem, a cigarette package in which a label is attached so as to cover the barcode of the cigarette pack is also known (Patent Document 1).
In the case of Patent Literature 1, a stamp-type label sticking device is used for sticking a label, but a roller-type label sticking device (Patent Literature 2) is also known instead of this stamp method.

US Patent Publication US 2012/0279882 A1 JP 2007-62776 A

Since the stamp-type label sticking device as in Patent Document 1 requires intermittent transfer to the cigarette package, the productivity of the cigarette package with the label attached is low.
On the other hand, the roller type label applicator permits continuous transport of the cigarette package, but in this case, it is necessary to accurately match the supply speed of the label and the transport speed of the cigarette pack in the label applicator. For this reason, at least one of the label sticking device and the continuous transport system of the cigarette package must be greatly modified, and it is not easy to apply the roller type label sticking device to the cigarette pack continuous transport system.

  The present invention has been based on the above-mentioned circumstances, and its purpose is to apply a cigarette package to a continuous transfer system of cigarette without facilitating productivity, and a method for applying the label to a cigarette package. Is to provide.

The above-described object is achieved by the cigarette package label applicator according to the present invention. The cigarette package, which is a label application object, has the following configuration.
The cigarette package includes a pack row in which a plurality of cigarette packs are arranged side by side, a transparent outer packaging material that wraps the pack row, and pack identifiers respectively provided on one side of each cigarette pack. The pack identifier of the cigarette pack located at the end of the row is visible through the outer packaging material as the specific pack identifier located on the end surface of the cigarette package, and the label covers the specific pack identifier. While being affixed to the cigarette package, it has a package identifier different from the pack identifier.

Assuming the cigarette package described above, the label applicator of the present invention is
A transport path for continuously transporting the cigarette package at a constant transport speed in a state where the cigarette package is present at a constant interval and the specific pack identifier is directed to the side;
Affixing position of the label defined in the transfer path;
A label supply unit for sequentially supplying the labels to the attaching position,
A feeding path having an end in the vicinity of the sticking position, intermittently feeding the labels arranged at intervals along the feeding path, and the transfer speed from the end toward the sticking position A label supply unit that sequentially feeds at a faster feeding speed than
The cigarette package body is disposed rotatably at the affixing position and sandwiches the leading label fed to the affixing position between the end surface of the cigarette package body to be affixed and passes through the affixing position. Along with the transfer, an affixing roller that affixes the leading label to the end surface of the affixing target;
A control unit for controlling the feeding of the leading label,
The label sticking device is configured to absorb the excessive feeding of the leading label due to the speed difference between the feeding speed and the sticking speed between the terminal end and the end surface of the sticking target. It further comprises a space that can bend the leading label toward the end face of the object to be pasted (Claim 1).

According to the label sticking device of the present invention, the leading edge of the leading label is placed between the sticking target end face of the cigarette package passing the sticking position and the sticking roller as the leading label is fed from the end of the supply path. Is first sandwiched, whereby initial adhesion of the leading label to the end face to be pasted is performed.
Here, since the feeding speed (label feeding speed) of the leading label fed from the end of the feeding path is faster than the transporting speed of the cigarette package, the leading label feeding due to the difference between these speeds. However, the surplus feed is absorbed by the leading label curving convexly toward the end face to be pasted in the above-described space.

  Therefore, even if the transport speed of the cigarette package is slower than the feeding speed of the leading label, the leading label following the leading edge is not sandwiched between the end surface of the sticking target and the sticking roller, There is no collision with the end face. As a result, the curvature of the leading label described above is eliminated as the leading label sticks to the end face of the sticking target, and the leading label covers the entire area along the sticking end face. Affixed neatly.

The object of the present invention is also achieved by a method for applying a label on a cigarette package, and the application method includes steps corresponding to the configuration of the aforementioned label application device, and exhibits the same operations and effects as the label application device (claims). 4).
Other objects and effects of the present invention will become clear from the following description.

  The cigarette package label affixing device and the affixing method thereof according to the present invention (Claims 1 and 4) allow a speed difference between the leading label feeding speed and the cigarette packaging transport speed, and the feeding speed. Since this is faster than the transfer speed, it can be easily applied to a transfer system of a cigarette package without reducing the productivity of the cigarette package with a label attached thereto.

FIG. 1 is a perspective view of a cigarette package to which a label is attached. It is an end view of a cigarette package with a label attached thereto. It is the schematic of the label sticking apparatus which concerns on one Embodiment of this invention. FIG. 4 is a diagram showing a state in which labels are fed out from the state shown in FIG. 3. It is a figure which shows the state which affixed the label progressed from the state shown in FIG. It is a figure which shows the state from which the sticking of a label reaches the final stage from the state shown in FIG.

Referring to FIG. 1, the cigarette package includes two pack rows R, and these pack rows R are stacked one above the other when viewed in the illustrated state. Each pack row R has, for example, five hinge lid type cigarette packs P. These cigarette packs P are arranged side by side along the longitudinal direction of the pack row R.
Each cigarette pack P is printed with a pack identifier such as a barcode or QR code (registered trademark) on one side. Therefore, in each pack row R, the pack identifier of the cigarette pack P positioned at the end is exposed as the specific pack identifier CC on the end surface on the same side of the pack row R. The pack identifier indicates product information of each cigarette pack P.

The cigarette package further includes a transparent film F as an outer packaging material. The film F is folded around the two-stage pack row R by a known folding procedure, and the two-stage pack row R is hermetically wrapped. The film F has an opening line extending in the longitudinal direction of the pack row R, and this opening line is formed of a perforated row, for example. Therefore, the film F can be easily opened along the opening line.
Since the film F is transparent as described above, the specific pack identifier CC of each pack row R becomes visible through the film F, and may be erroneously read as product information of the cigarette package itself by a code reader (not shown). There is.

In order to avoid such problems, the cigarette package further includes a label L, and this label, as is clear from FIG. 2, covers the end face (film F) of the cigarette package so as to cover the specific pack identifier CC of each pack row R. ). Such a label L is printed with a package identifier PC such as a barcode or QR code (registered trademark), and the package identifier PC indicates product information of the cigarette package. 1 and 2, the pack identifier CC and the package identifier PC are shown only in the print area.
If the label L described above is affixed to the cigarette package, the code reader does not erroneously read the specific pack identifier CC, and the code reader can accurately read the package identifier PC of the cigarette package itself.

FIG. 3 schematically shows an embodiment of a label sticking device for sticking a label L to each cigarette package.
The labeling device is provided with a transfer path 10. The transfer path 10 extends vertically and continuously transfers the cigarette package CP1 before the label L is pasted and the cigarette package CP2 to which the label L is pasted at a constant transfer speed.

  Specifically, the upper end of the transfer path 10 is connected to a film wrapping machine, and this film wrapping machine manufactures a cigarette package CP1 in which the above-described two-stage pack row R is wrapped with a film F. Such cigarette packages CP1 are sequentially supplied to the upper end of the transfer path 10, and are continuously transferred downward on the transfer path 10. A paste position SP is defined in the middle of the transfer path 10, and when the cigarette package CP1 passes through the paste position SP, a label L is affixed to the cigarette CP1 as will be apparent from the following description. A cigarette package CP2 is formed. Thereafter, the cigarette package CP is transferred from the lower end of the transfer path 10 toward the boxing machine, and a predetermined number of boxes are packed in a cardboard box (not shown) by the boxing machine.

On the transfer path 10, a certain interval is secured between the cigarette package CP1 adjacent to each other along the transfer path 10, or between the cigarette package CP1 and the cigarette package CP2. In addition, the cigarette packages CP1 and CP2 on the transfer path 10 hold a horizontal posture with the end surface EF having the specific pack identifier CC facing the side of the transfer path 10.
A label supply unit 12 is disposed on the side of the transfer path 10, and the label supply unit 12 includes a label L supply path 14. This supply path 14 has a terminal 16 in the vicinity of the affixing position SP described above, extends obliquely upward from the terminal 16 to the side of the transfer path 10, and is connected to a label supply roll RR via a tension roller 18. The label supply roll RR is mounted on the supply reel 20 and defines the starting end of the supply path 14.

The label supply roll RR is formed by winding a label carrying tape LT. The label carrying tape LT includes a web W as a release paper and a number of labels L attached to one side of the web W. These labels L Is affixed in the longitudinal direction of the web W with a certain interval. That is, the label L is formed such that the surface on the web W side is an adhesive surface.
The label L is pre-printed with the above-described package identifier PC on the surface opposite to the adhesive surface, or the label L has a package on the surface of the label L by a printing device (not shown) arranged in the transfer path 10. The identifier PC is printed.

  The end 16 of the supply path 14 described above is formed by the tip of the peeling plate 22, and the collection path 24 of the web W extends upward from the tip. The upper end of the collection path 24 is connected to the take-up reel 26. In the collection path 24, for example, a feed roller unit 28 and a tension roller 30 are sequentially arranged from the end 16 side of the supply path 14, and the feed roller unit 28 is disposed between the feed roller 32 and the feed roller 32, that is, the collection path 24, that is, And a pinch roller 34 that sandwiches the web W, and the feed roller 32 is connected to a feed motor including a servo motor.

  Here, the label carrying tape LT fed out from the label supply roll RR is guided along the supply path 14 and the recovery path 24, and the leading end is connected to the take-up reel 26. When the feed roller 32 is driven in this state, the label carrying tape LT is supplied on the supply path 14 at a constant supply speed that is faster than the transfer speed of the cigarette package CP1 (CP2) described above, and The supply direction is suddenly changed at the end 16 of the supply path 14, that is, at the tip of the peeling plate 22.

As a result, the leading label L is peeled off from the web W of the label carrying tape LT on the supply path 14, and the leading label L is fed at a constant feeding speed from the end 16 of the supply path 14 to the affixing position SP described above. It will be paid out. Since the feeding speed here matches the supply speed of the label carrying tape LT, it goes without saying that the feeding speed is faster than the transport speed of the cigarette package CP1 (CP2).
On the other hand, the web W from which the label L has been peeled is wound around the take-up reel 26 via the collection path 24 and is collected on the take-up reel 26.

  A sticking roller 36 is rotatably disposed on the side of the transfer path 10 and below the end 16 of the supply path 14. Specifically, the sticking roller 36 is positioned at the same height level as the sticking position SP, and is urged toward the transfer path 10 by the pressing spring 38 in the direction of arrow A in FIG. It is possible to slightly enter the transfer area of the body CP1. Therefore, when the cigarette package CP1 passes the application position SP, the end surface EF of the cigarette package CP1 comes into contact with the application roller 36, so that the application roller 36 resists the urging force of the pressing spring 38 and the arrow A Retreats in the direction of arrow B opposite to the direction of, and comes into rolling contact with the end face EF as the cigarette package CP1 is transferred.

The supply of the label holding tape LT, that is, the feeding of the leading label L from the end 16 of the supply path 14 is intermittently performed according to the transfer of the cigarette package CP1, and therefore the label applicator of one embodiment is A feed roller unit 28, that is, a control unit 40 that controls driving of the feed motor is provided. The control unit 40 includes a passage sensor 42 and a controller 44.
The passage sensor 42 is disposed upstream of the sticking position SP in the transfer path 10, detects passage of the cigarette package CP1, and transmits a detection signal to the controller 44. For example, a reflection type photoelectric sensor can be used as such a passage sensor.

On the other hand, when the controller 44 receives the detection signal from the passage sensor 42, the controller 44 drives the feed motor 33 for a predetermined time at a predetermined timing, and intermittently feeds the label carrying tape LT on the supply path 14 via the feed roller unit 28. To supply.
Next, the operation of the label sticking apparatus of one embodiment will be described with reference to FIGS. 4 to 6, and the label sticking method performed by the label sticking apparatus will be clarified from the description here.

First, when the intermittent supply of the label carrying tape LT is stopped, the label sticking device is in the state shown in FIG.
Specifically, at this time, the cigarette package CP2 to which the label L has been affixed in the previous label affixing operation is in a state immediately after passing through the affixing roller 36.
Thereafter, if the passage sensor 42 detects the passage of the cigarette package CP1 upstream of the sticking position SP, after this detection, the controller 44 drives the feed motor 33, that is, the feed roller 32 at a predetermined timing. The process is resumed, and the leading label L is directed from the end 16 of the supply path 14 toward the sticking position SP (see arrow M in FIG. 4), and is fed out for a predetermined period. At this time, it should be noted that the adhesive surface of the label L is directed upward.

Specifically, as is apparent from FIG. 4, the cigarette package CP1 to be applied next toward the application position SP, that is, the lower edge of the application target end face EF reaches the application roller 36, and at the same time the leading label For example, the driving of the feed roller 32 is controlled so that the front end edge of L comes into contact with the lower edge of the application target end face EF.
Therefore, immediately after this, the leading edge of the leading label L is sandwiched between the sticking roller 36 and the sticking target end face EF, and the leading label L is initially bonded to the sticking target end face EF via the adhesive surface. Is done.

On the other hand, in spite of the initial label L being adhered in this way, the feeding speed of the leading label L is faster than the transfer speed of the cigarette package CP1 as described above. The sticking speed (transfer speed) of the leading label L does not catch up with the feeding speed, and therefore the leading label L is convexly curved toward the sticking target end face EF (see the two-dot chain line in FIG. 4). The curvature of the leading label L absorbs the speed between the feeding speed and the sticking speed (transfer speed).
For this reason, in the present embodiment, a sufficient space S (see FIG. 4) is secured between the sticking target end face EF and the end of the supply path 14 to allow the leading label L to be bent.

Even if the intermittent supply of the label carrying tape LT, that is, the feeding of the leading label L is stopped, the cigarette package CP1 (CP2) on the transfer path 10 continues to be transferred. As the body CP1 passes the sticking roller 36, the leading label L is stuck along the sticking target end face EF via the sticking roller 36, and as the sticking progresses here, the leading label L The rear end of L is detached from the end 16 of the supply path 14 while being separated from the web W (see FIG. 5).
As a result, as is apparent from FIG. 6, the leading label L can be reliably and cleanly applied to the sticking target end surface EF of the cigarette package CP1 from the leading end to the trailing end.
Thereafter, the label sticking apparatus is in the state shown in FIG. 3, and the label L is continuously stuck to the cigarette package CP1 passing through the sticking position SP by repeating the above-described operation.

  As is apparent from the above description, the label sticking device of the present embodiment allows a speed difference between the transfer speed (sticking speed) of the cigarette package CP1 and the supply speed (feeding speed) of the label L. In addition to being easily applicable to the transfer path 10, the label L can be reliably and cleanly attached to the end surface EF to which the cigarette package CP1 is attached.

The present invention is not limited to the above-described embodiment, and various modifications can be made.
For example, the cigarette package can include one or three or more pack rows, and the number of cigarette packs in each pack row is not limited to five.
Moreover, in one Embodiment, although the transfer path | route of the cigarette package was vertical, the transfer path | route may be extended horizontally and layouts, such as a transfer path | route and a supply path | route, can be changed arbitrarily.
