[0001]

The present invention relates to a label sticking apparatus,
In particular, the present invention relates to a label sticking apparatus that peels a label from a band-shaped backing sheet on which labels are temporarily attached at equal intervals, and automatically sticks the label to a sticking object being conveyed by a conveyor.

[0002]

2. Description of the Related Art In a label sticking apparatus, a band-shaped backing sheet on which labels are temporarily attached with an adhesive at equal intervals is supplied to a backing sheet conveyance path by being rewound from a supply reel for winding and storing the band-shaped backing sheet. Then, after a necessary display such as a product number and a price is printed by a printing device provided on the backing paper transport path, the band-shaped backing paper is folded and moved at a tip end of a label peeling plate provided on the backing paper transport path. As a result, the label that is harder than the mount is peeled off. At this time, it is necessary to intermittently move the band-shaped mount by a distance for peeling off one label with the peeling plate. Therefore, the band-shaped mount moves by the distance for peeling off one label and stops. Next, the surface of the label (the surface to which no glue is attached) peeled off by the peeling plate and fed out of the peeling plate is provided immediately in front of the peeling plate with the aid of air from an air blowing pipe. The label is sucked and held on the label suction surface of the sucker, and waits for the object to be adhered to be conveyed by a separate conveyor. Then, when the object is conveyed, the suction board is switched from the suction operation to the air discharge operation, and the label is attached to the application position of the object by air discharge.

However, due to the degree of adhesion of the adhesive between the band-shaped backing sheet and the label or the variation in the stop timing of the band-shaped backing sheet, when the label fed out to the front of the peeling plate is adsorbed by the suction plate, the rear end of the label is removed. There is a case where the part is not completely separated from the band-shaped backing paper, that is, the so-called glue is poor. For this reason, the suction disc switches from the suction operation to the air discharge operation while the rear end of the label is not separated from the band-shaped backing sheet, and the label is attached to the object. As a result, the sticking position of the label stuck on the object to be stuck is deviated from the correct sticking position, or the orientation is changed.

[0004] From this, the conventional label sticking apparatus, in order to eliminate the factors that deteriorate the sticking accuracy, for example, the Japanese Utility Model Application
As disclosed in Japanese Patent No. 3926, the adsorbing disc can be moved forward and backward by a predetermined distance in the horizontal direction with respect to the peeling plate, and the label adsorbed by the sucking disc is separated from the peeling plate, thereby making the label rear end Some devices have been devised to completely separate the part from the band-shaped backing paper. For the same purpose, as disclosed in Japanese Patent Publication No. 59-13377, there is also a device in which the suction disk can be moved up and down by a predetermined distance in the direction of the adherend.

[0005]

However, the conventional label sticking apparatus (Japanese Utility Model Publication No. 63-3926) which moves the suction plate forward and backward with respect to the peeling plate in the horizontal direction, has a suction force for sucking the label to the suction plate. If the rear end of the label is more strongly adhered to the band-shaped backing paper, if the suction plate is moved away from the release plate, the label will shift from the correct suction position of the suction plate, and the There is a drawback that it is not possible to paste with high accuracy when pasting.

On the other hand, in a conventional label sticking apparatus (Japanese Patent Publication No. Sho 59-13377) in which a suction disk is moved up and down in the direction of a material to be stuck, a distal end 1A of a peeling plate 1 is rounded as shown in FIG. Due to the R angle, even when the suction plate 3 is moved downward, even the portion of the adhesive layer 4A from which the label 4 has been peeled off may adhere to the band-shaped backing sheet 5 again. in this way,
When the suction plate 3 is forcibly moved downward toward the adhered object 7 being conveyed by the conveyor 6 in a state where the adhesion portion between the label 4 and the band-shaped backing sheet 5 is large, a strong tensile force is applied to the band-shaped backing sheet 5. As a result, the supply reel (not shown) may be rotated by pulling the band-shaped backing sheet 5, and the band-shaped backing sheet 5 in a stopped state may be displaced from a correct stop position, which may hinder subsequent printing accuracy, peeling accuracy, and the like. The problem of coming up occurs.

The present invention has been made in view of such circumstances, and provides a label sticking apparatus capable of accurately peeling a label from a band-shaped backing sheet and sticking the label to a sticking position of an object to be stuck with high accuracy. The purpose is to do.

[0008]

According to the present invention, in order to achieve the above object, a plurality of labels on which a plurality of labels are temporarily attached at regular intervals are wound and stored, and the band is rewound to a backing paper transport path. A supply reel for supplying, a printing device provided on the mount transport path for printing on the label, a peeling member for peeling the printed label from the strip-shaped backing paper, and sucking and holding the label peeled by the peeling member. A means for attaching a label to the object to be affixed while waiting for the object to be affixed to be conveyed by a separate conveyance means, and the release plate by blowing air toward a label suction surface of the affixing means. An air blowing member for sucking and complementing the label peeled off from the label suction surface, and moving the sticking means away from the peeling member after sucking the label on the label suction surface. And a moving means for returning the sticking means to its original position after the label has been attracted to the object to be stuck, and complementing the peeling of the label from the cardboard. It is characterized in that it is configured to move following the movement of the means.

[0009]

According to the present invention, the label is peeled off from the band mount by a peeling member and is adsorbed on the label suction surface of the sticking means due to the degree of adhesion of the adhesive glue of the label temporarily attached to the band mount and minute variations in the stop timing of the band mount. When the label is attached, the rear end of the label may remain adhered without being cut off from the band-shaped backing paper, which is a factor that deteriorates the sticking accuracy when sticking the label to the sticking object.

According to the label sticking apparatus of the present invention, the air blowing member for sucking and complementing the label peeled off by the peeling member onto the label suction surface is moved following the movement of the sticking means. Thereby, when the label is peeled from the band-shaped backing paper by the peeling member and is adsorbed on the sticking means, the air blowing member blows the air on the peeling surface of the label being peeled and keeps the label horizontal by keeping the label horizontal. The conventional function of facilitating the sticking of the sticking means to the label suction surface is performed. Then, when the sticking unit that has absorbed the label is moved away from the peeling member to supplement the peeling of the label from the band-shaped backing sheet, the air blowing member moves following the movement of the sticking unit and sticks to the sticking unit. Air is blown on the peeled surface of the label. Thereby, the label can be held on the label suction surface by both the suction force of the sticking means and the pressing force of the air blown out from the air blowing member, so that the label rear end is adhered to the band-shaped backing paper. The label peeling can be complemented without deviating from the adhesive force and the label adsorption position is not shifted. Therefore, the label sucked and held on the label suction surface of the sticking means can be accurately stuck to the object to be stuck.

Further, when the attaching means is separated from the peeling member,
If the adhesive glue pulls the thread between the rear end of the label and the band-shaped backing sheet, the thread from the air blowing member is easily cut by the air, so that the label rear end can be more easily peeled off from the band-shaped backing sheet. Can be. When the label has been pasted on the object to be pasted, the pasting means returns to the original position and sucks the next label to be peeled.

And an air-driven cylinder 42 for moving the suction plate 34 in a horizontal direction with respect to the peeling plate 18, and a label suction surface of the suction plate 34 attached to the separation plate 18 of the suction plate 34 while following the movement of the suction plate 34. And an air blowing pipe 44 for blowing air toward the air outlet.

Each of the above devices is a label sticking device 10.
Each of the devices is supported by a corresponding frame 46, and the operation of each of the devices is operated at an appropriate timing by an operation program previously input to the controller 48. Next, the sticking mechanism 26 which is an improved part of the present invention will be described in more detail with reference to FIG. 2. Two air tubes are connected to the suction plate 34, and one air tube 50 is connected to the negative pressure generator 36. The negative pressure generator 36 is connected to the switch 38. The other air tube 52 is connected to the switch 38 via a pressure opening / closing valve 54. The switch 38 is controlled by the controller 48 (see FIG. 1). As a result, the label 3 peeled off from the band-shaped backing material 12 by the peeling plate 18
When the suction nozzle 2 is sucked by the suction disk 34, a suction force is generated in the suction disk 34 by the negative pressure generator 36, and the label 32 is suction-held on the label suction surface 58 of the suction disk 34, and the label 32 is attached to the object 24. At the time of sticking, the path of the negative pressure generator 36 is closed by the switch 38 and the air discharge path is opened, so that the label 32 is stuck to the object 24 by the wind pressure of the air discharged from the suction plate 34. .

An air discharge pipe 44 is provided on the peeling plate 18 side of the suction plate 34 and supported by a downwardly projecting arm 56 in the width direction of the suction plate 34. A plurality of air nozzles 60 that blow air toward the surface 58 are formed. One end of the air blowing pipe 44 is closed, and an air tube 62 extending from the other end is connected to the switch 38. An air-driven cylinder 42 is attached to the suction plate 34 on the opposite side of the air blowing pipe 44. And, two air tubes 64 extending from the cylinder 42,
64 is connected to the switch 38, and the switch 38 switches the air supply to the two air tubes 64, 64, whereby the piston of the cylinder 42 can be moved in the XX direction in the figure. As a result, the suction disk 34 and the air pipes 44 attached to the suction disk 34 advance and retreat in a horizontal direction between directly above the adhered object 24 being conveyed by the separate conveyor 22 and the distal end portion 18A of the peeling plate 18. It is designed to move. The timing of the advance / retreat movement is controlled by the controller 48, and the label 32 peeled off from the band-shaped backing sheet 12 by the peeling plate 18 is moved away from the peeling plate 18 immediately after the label 32 is attracted to the suction plate 34, so that When the label 32 is pasted on 24, it returns to the original position again.

Next, the operation of the label sticking apparatus 10 of the present invention configured as described above will be described with reference to an example of sticking a label to the cardboard box 24. The band-shaped backing sheet 12 on which the plurality of labels 32 are temporarily attached at equal intervals is rewound from the supply reel 14 that winds and stores the band-shaped backing sheet 12, and is supplied to the backing sheet conveyance path. The printing mechanism 16 prints necessary information, such as a date, on one label that has reached the printing mechanism 16 while the belt-shaped mount 12 to which the label 32 is temporarily attached is conveyed on the mount conveying path. Further, as shown in FIG. 3, the band-shaped backing 12 on which the printed label 32 is temporarily attached is folded back at the leading end 18A of the peeling plate 18 provided on the backing sheet transport path, so that the label temporarily attached to the band-shaped backing 12 is provided. 32 is peeled off and fed out toward the label suction surface 58 of the suction board 34.
The fed label 32 is kept horizontal without being bent by the air blown out from the air blowing pipe 44, and
4 is adsorbed to the label adsorbing surface 58 of the conveyor 22 provided separately.
Waits until the cardboard box 24 is conveyed. At this time, due to the degree of adhesion of the adhesive of the label 32 temporarily attached to the band-shaped backing sheet 12 and the minute variation in the stop timing of the band-shaped backing sheet 12, the label 32 is separated from the band-shaped backing sheet 12 by the peeling plate 18.
When the label is peeled off and sucked on the label suction surface 58 of the suction board 34, the label rear end 32A may remain adhered to the cardboard box 24 without being cut off from the band-shaped backing paper 12, and the label 32 is attached to the cardboard box 24. This is a factor that deteriorates the sticking accuracy.

Therefore, in order to supplement the peeling of the label from the band-shaped backing sheet 12 by the peeling plate 18, the cylinder 4 is removed as shown in FIG.
2 retracts the suction plate 34 that has sucked the label 32 away from the tip 18A of the peeling plate 18 and moves it to a predetermined position in the direction of arrow A to stand by. At this time, in the label sticking apparatus of the present invention, the air blowing pipe 44 is connected to the suction board 34 as described above.
Therefore, the air blowing pipe 44 can follow the movement of the suction board 34 and move to follow the movement of the suction board 34 to continuously blow air on the peeling surface of the label 32 sucked by the suction board 34. As a result, the label 32 is held by both the suction force of the suction plate 34 and the pressing force of the air blown out from the air blowing pipe 44. Therefore, when moving the suction plate 34 away from the peeling plate 18, the label 32 The adhesive strength between the rear end portion 32A and the band-shaped backing sheet is not lost. Therefore, the label rear end portion 32A can be reliably peeled off from the band-shaped backing sheet 12 without shifting the label suction position on the label suction surface 58 of the suction disc 34. Further, when the adhesive paste pulls a thread between the label rear end portion 32A and the band-shaped backing sheet 12 when the suction board 34 is separated from the peeling plate 18, the thread is easily cut by the air from the air blowing pipe 44. The rear end 32A of the label can be further easily separated from the band-shaped backing material 12.

Next, the air blowing from the air blowing pipe 44 is stopped, and the switch 38 is switched to operate the suction board 34.
Air is discharged from the Then, the label 32 is attached to the cardboard box 24 conveyed by the separate conveyor 22 by the wind pressure of the discharged air. Next, when the label 32 is pasted on the cardboard box 24, the cylinder 42 extends in the direction opposite to the arrow A to move the suction disk 34 to the original position.

By repeating the above operation, the suction disk 3
Since the label 32 can be reliably separated from the band-shaped backing sheet 12 without shifting the label suction position in 4, the label 32 can be stuck to the cardboard box 24 with high accuracy. As described above, the label sticking apparatus 10 of the present invention
When the label 32 is peeled off from the band-shaped backing sheet 12 by the peeling plate 18 and the label 32 is sucked to the suction board 34, the air blowing pipe 44
Can perform the conventional function of facilitating the label 32 to be attracted to the label attracting surface 58. And label 3
When the suction plate 34 having sucked 2 is moved so as to be separated from the peeling plate 18, the air blowing pipe 44 sticks the label 32 on a label suction surface 58 of the suction plate 34 as in a conventional label sticking device. Accuracy deteriorates, band-shaped backing 1
The function of reliably peeling the label 32 from the band-shaped backing material 12 can be performed without adversely affecting the printing accuracy and the peeling accuracy of the label 32 temporarily attached to the label 2.

Therefore, the label sticking apparatus 10 of the present invention is
The sticking accuracy of sticking a label to an object to be stuck can be improved. In this embodiment, the case where the suction disk is moved in the horizontal direction has been described. However, the present invention is not limited to this, and the features of the present invention can be applied to any direction in which the suction disk is separated from the peeling plate. be able to. Further, the air blowing pipe 44 may be provided separately from the suction board 34.

[0022]

As described above, in the label sticking apparatus of the present invention, the label blown off by the peeling member is moved by the air blowing member which follows the movement of the sticking means so as to suck and complement the label on the label suction surface of the sticking means. I did it. As a result, the adhesive at the rear end of the label from the band-shaped backing sheet is more excellent, and the peeling of the label can be complemented, and the displacement of the adsorption position of the label adsorbed on the label adsorption surface can be prevented. Can be accurately attached to the attachment position of the object.

Therefore, the label sticking apparatus of the present invention has a problem in that the label is misaligned on the suction plate as in the conventional label sticking apparatus and the sticking accuracy is deteriorated. The label can be accurately attached to the object without adversely affecting the accuracy or the like.
