[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label sticking apparatus for sticking a label, such as a bar code, on a material to be stuck.

[0002]

2. Description of the Related Art For example, a label sticking apparatus is known as an apparatus for sticking a printed label such as a bar code on an article or the like conveyed through a conveying mechanism such as a belt conveyor. . A conventional label sticking device 50 whose outline is shown in FIG. 3 is provided next to a print issuing unit 51.

In the print issuing section 51, the label 52 is printed by the printing means 54 while being driven by the driving means 53, and then the label 52 is rapidly rotated by the peeling plate 55, whereby the label body 52a is peeled off from the mount 52b. Is done. Here, the label body 52a is separated from the mount 52b by the airflow from the blow-up nozzle 56 that operates simultaneously with the issuance of the label, and is sent to the adjacent label sticking device 50.

[0004] The peeled label body 52 a is sucked by a fan 57 provided in the housing of the apparatus and held on a holding surface 58. After the label body 52a is once sucked on the holding surface 58 by the suction force of the fan 57, the blowing means 57 blows the label body 52a and is attached to the target.

[0005]

According to the spraying means 59 in the conventional label sticking apparatus 50, the amount and pressure of the air to be jetted are not sufficient, and the force required to stably fly the label body 52a over a long distance is not sufficient. In some cases, it could not be obtained.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a label sticking apparatus which can surely stick a label body to a distant object.

[0007]

According to the present invention, there is provided a label sticking apparatus which sprays a label body peeled off from a backing sheet with an injection nozzle (11).
In a label sticking apparatus for spraying and sticking an object with air blown out from the air supply unit, an air storage unit (16) provided between an air supply source and an injection nozzle for keeping the air blown to the label body at a predetermined pressure and storing the air. ), The injection nozzle (11) is formed in a substantially conical shape, a plurality of blowout holes (14) at the tip, and a plurality of blowout holes respectively provided between the adjacent blowout holes along the blowout direction. Partition wall (1
3).

[0008]

The compressed air is supplied to each injection nozzle from an air tank storing a sufficient amount of compressed air. When compressed air having a predetermined pressure is injected from the outlet of the injection nozzle, the surrounding air is entrained therein and flows in the same direction as the compressed air from between the partition walls. The label body is affixed to a distant object by a sufficient flow of air.

[0009]

An embodiment will be described with reference to FIGS.
Components similar to those in the related art are given the same reference numerals as in FIG. The label sticking apparatus 1 of the present embodiment includes:
The lower surface of the housing is the holding surface 58 of the label 52a. The holding surface 58 is partially open, and the injection nozzle 11 of the spraying means 10 is provided in this opening.

[0010] As shown in FIG.
In the first embodiment, a plurality of partition walls 13 are provided at predetermined intervals on the peripheral surface of a substantially conical main body 12 along the ejection direction. Body 1
A compressed air blowing hole 14 is opened between the partition walls 13 at the front end of the nozzle 2. When compressed air is injected from the blowout holes 14, the nearby air is entrained by the momentum and is blown out between the partition walls 13. The number of the spray nozzles 11 is appropriately arranged in a pattern according to the shape of the label body 52a held on the holding surface 58.

As shown in FIG. 1, each of the injection nozzles 11
Is connected to an air tank 16 as an air storage unit via a solenoid valve 15 by a pipe. This air tank 1
6 stores compressed air at a predetermined pressure, and is replenished as needed. In the figure, reference numeral 17 denotes a pressure gauge.

As shown in FIG. 1, the release plate 5 of the holding surface 58
At the end on the 5th side, a blow-down nozzle 2 as a label body moving means is provided. The nozzle hole of the blow-down nozzle 2 is located inside the opening of the holding surface 58, and is directed obliquely downward along the moving direction of the label body 52a.

At the other end of the holding surface 58, a stopper 3 is provided. The stopper 3 is linked to the air cylinder 4 and can reciprocate at a desired timing between a position protruding downward from the holding surface 58 and a position retracted into the holding surface 58. . The stopper 3 is made of a material such as Teflon or the like that does not easily stick.

The blow-down nozzle 2, the air cylinder 4 of the stopper 3, and the blow-up nozzle 56 are all connected to an air supply source (not shown) via an electromagnetic valve. These electromagnetic valves and the electromagnetic valve 15 of the air tank 16 are operated by control means (not shown) in synchronization with the operation of the print issuing unit 51. Note that the fan 57 is constantly driven.

Next, the operation of the present apparatus will be described. First, the print issuing unit 51 operates to issue the label body 52a, and at the same time, the blowing nozzle 56 operates. The blow-up nozzle 56 blows the tip of the label body 52a to promote separation from the mount 52b, and further prevents the label body 52a moving to the holding surface 58 while separating from the mount 52b from hanging down.

Immediately before the label issuance is completed, the air cylinder 4 operates to lower the stopper 3, and at the same time, the blow down nozzle 2 operates. The air jetted from the blow-down nozzle 2 flows between the holding surface 58 and the label body 52a in the direction of the stopper 3 along the holding surface 58. Due to this rapid flow of air, the label body 52a is pressed against the holding surface 58, and is moved at a stretch in the direction of the stopper 3 to come into contact with the stopper 3. As a result, the label body 52a is completely separated from the backing sheet 52b, and is positioned at a predetermined position on the holding surface 58. When the label body 52a is positioned, the blowing of the blow-down nozzle 2 stops and the stopper 3 is retracted.

Next, the solenoid valve 15 is opened, and compressed air of a predetermined pressure is supplied from the air tank 16 to each of the injection nozzles 11 of the spraying means 10. Here, since the compressed air is supplied from the air tank 16 having a sufficient capacity, the pressure does not drop when the air is ejected.

When compressed air maintained at a predetermined pressure is injected from the outlet 14 of the injection nozzle 11, atmospheric air around the injection nozzle 11 is entrained in the flow of compressed air, and the space between the partition walls 13 is formed. Is injected to the label body 52a together with the compressed air. The label body 52a is
A sufficient flow of air causes the air to travel a long distance and be reliably attached to a relatively distant object.

In the above-described embodiment, the air tank 16 is provided as the air storage unit. However, a sufficient amount of air may be stored by lengthening the air piping. Further, in the injection nozzle 11 of the spraying means 10, the number and arrangement of the partition walls 13 and the outlet holes 14 can be arbitrarily determined so that the entrainment of the atmospheric air becomes effective.

[0020]

The label sticking apparatus of the present invention is provided with an air storage section between the air supply source and the injection nozzle for keeping the air blown to the label body at a predetermined pressure and storing the air, and the injection nozzle is formed in a substantially conical shape. By providing a plurality of blowout holes at the tip and providing a plurality of partition walls along the blowout direction between the adjacent blowout holes, it is possible to reduce a pressure drop at the time of air injection from the injection nozzle. The label body can be stably affixed to the object, and the surrounding air can be entrained and blown out when the air is blown, and the label body can be scattered far enough with a sufficient amount of air to securely affix to the object. be able to.
