Description

The present invention particularly relates to a labeling apparatus and a label suitable for use in a box that is washed for repeated use, which is called an oricon used for picking or the like, or a returnable box used for transporting fresh foods or frozen products. It relates to the pasting method.

Conventionally, returnable boxes that are used repeatedly for transporting fresh foods and frozen products are collected with a label printed with information such as the shipping destination as needed. (For example, refer to Patent Document 1).
In addition, a folding box called “Oricon” that temporarily stores picked goods is also washed as appropriate because label pieces for displaying the contents are repeatedly attached.
In this way, it is best to dry the returnable box (box body) from which the label has been peeled off and cleaned, but if the number is small, the cleaned returnable box (box body) must be used immediately. You may not get.
Therefore, a label sticking machine is known that removes water droplets from the box at a position in front of the sticking means (see, for example, Patent Document 2).
According to this label sticking machine, it is provided with a pair of rotatable guide rollers that are opposed to each other so as to sandwich the both side plates of the box at a position in front of the sticking means, and the guide roller is a cylinder having a number of water passage holes. The cylindrical wall surface of the body is covered with a water-absorbing material, and by the guide roller, the water-absorbing material absorbs and removes water droplets, and the adhesive layer of the label to be applied does not absorb moisture and the adhesive force does not decrease. Therefore, it is not necessary to dry the box wet with water.
However, since the label sticking machine (Patent Document 2) needs to provide a pair of guide rollers at the front position of the sticking means, it is inevitable to increase the size of the apparatus, and the cylindrical wall surface of the guide roller is made of a water absorbent material. There is a problem that the apparatus becomes expensive due to the complexity, such as covering and allowing water absorbed by the water-absorbing material to be discharged outside through the cylindrical body.
JP-A-6-198264 Japanese Patent Laid-Open No. 5-338632

The present invention has been made paying attention to the above-mentioned problems, and it is possible to remove the moisture of an object to be adhered before label application, such as a returnable box, with a simple structure so that stable label application can be performed. It is an object of the present invention to provide a label affixing device and a label affixing method.

The label sticking device according to claim 1 is provided with a suction plate on which a suction surface for sucking and holding an adhesive label piece is formed, and the label piece is attached by moving the suction plate toward an object to be attached.

It is a device.

Next, an embodiment of the “angle adjusting means” will be described mainly with reference to FIG.
As shown in the figure, the angle adjustment mechanism 22 as “angle adjustment means” includes a first support portion 23 and a second support portion 24.
The first support portion 23 is provided with an attachment arm 25, one end of the attachment arm 25 is fixed to the suction plate 15, and the other end rotatably supports the nozzle 21 via an engagement pin 26. ing.
The second support portion 24 includes a first mounting arm 27, a second mounting arm 28, and a solenoid 29. One end of the first mounting arm 27 is fixed to the arm 20 and the other end. Has a solenoid 29 fixed thereto. The solenoid 29 has a plunger 30 that can move forward and backward, and the tip of the plunger 30 is attached to one end of the second attachment arm 28. The other end of the second mounting arm 28 supports the nozzle 21 via an engagement pin 31 so as to be rotatable. The amount of stroke of the solenoid 29 with respect to the plunger 30 is controlled by the control unit 9, and the angle of the nozzle 21 with respect to the affixing surface 35 a of the object 35 is adjusted by the amount of stroke of the plunger 30. It is what is done.
The tip of the nozzle 21 (the opening side not shown) is attached in a state of being retracted without protruding from the suction surface 15a of the suction plate 15 (upper side in FIG. 2). This does not interfere with the operation of attaching the label piece 11 to the attaching surface 35a due to the approach.

    Next, a method of attaching the label piece 11 will be described mainly using the flowchart of FIG.

    In step S01, the label piece 11 is peeled off. That is, the label continuum 2 supported by the supply shaft 3 is fed to the printing mechanism 4 and the peeling mechanism 5, and only the mount 10 is turned by the peeling plate 14 and wound on the mount winding shaft 6. In 4, the label piece 11 on which the desired printing is performed is peeled off.

    In step S02, the label piece 11 is sucked and held. That is, the label suction disk 15 positioned in the forward direction of the peeling mechanism 5 sucks and holds the label pieces 11 peeled by the peeling mechanism 5 by the suction surface 15a.

  In step S03, an operation of attaching the label piece 11 is started. In other words, the arm 20 of the sticking mechanism 7 is advanced in synchronization with the sticking object 35 transported on the transport belt 36, and the label piece 11 sucked and held on the label suction plate 15 is attached to the sticking surface of the sticking object 35. Close to 35a.

    In step S04, air A is blown toward the object to be pasted 35. That is, when the label piece 11 adsorbed and held on the label adsorbing plate 15 is brought close to (advanced) toward the adhering surface 35a of the object 35, a compressor (not shown) is operated at an arbitrary position, and the label adsorbing plate 15 The air A is blown toward the sticking surface 35a from the nozzle 21 attached so as to follow.

    In step S05, the label piece 11 is attached to a predetermined position of the object 35.

    In step S06, the label suction board 15 is returned and waited. That is, when the arm 20 of the sticking mechanism 7 is separated (retracted) from the object 35 and the label suction plate 15 is positioned in the forward direction of the peeling mechanism 5, the next label piece 11 is peeled off. wait.

As described above, when the arm 20 of the sticking mechanism 7 is advanced and the label piece 11 sucked and held on the label suction plate 15 is brought close to (advanced) toward the object 35, synchronization is performed immediately before the label piece 11 is stuck. Since the air A is blown toward the affixing surface 35a, the label piece 11 can be affixed stably and smoothly even if water droplets after washing adhere or dust adheres due to long-term storage. It is possible.
The angle of the air A blowing nozzle 21 with respect to the affixing surface 35a may be constant, or may be gradually increased inwardly (in accordance with the proximity of the adsorbing plate 15 to the adhering surface 35a (the adsorbing plate 15). You may make it change an angle to the side. If the angle of the nozzle 21 is changed in conjunction with the proximity of the suction disk 15 to the sticking surface 35a as in the latter, air A from the nozzle 21 is blown so as to lick the sticking surface 35a. In addition, reliable water removal is possible. It goes without saying that the nozzle 21 after changing the angle is returned to the original position (angle) with the separation from the sticking surface 35 a of the suction disk 15.

Next, another embodiment of the spraying means will be described with reference to FIGS.
In addition, about the part similar to previous embodiment, only the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

FIG. 4 is a schematic explanatory view showing a state in which the spraying mechanism is attached to the pasting mechanism 7.
The blowing mechanism 40 includes a cylindrical body 41 whose other end is connected to an air source such as a compressor (not shown), and an angle adjusting mechanism 42 as “angle adjusting means”.

Here, the cylindrical body 41 will be described mainly based on FIG. FIG. 5 is a schematic perspective explanatory view of the cylinder 41 viewed from the direction indicated by the arrow V in FIG. 4. The inside of the cylinder 41 is a hollow portion 43, and the hollow portion 43 is inserted in the longitudinal direction. A plurality of blowing holes 44 are provided in a row. A hose 45 is provided so as to pass through the hollow portion 43, and a tip end portion of the hose 45 is connected to an air source such as a compressor (not shown). When air (not shown) is blown, the air A is blown from the blow hole 44.

Returning to FIG. 4, the angle adjustment mechanism 42 includes a first support portion 46 and a second support portion 47.
The first support portion 46 is provided with a mounting arm 48, one end of the mounting arm 48 is fixed to the suction plate 15, and the other end rotatably supports the cylindrical body 41 via an engagement pin 49. is doing.
The second support portion 47 includes a first mounting arm 50, a second mounting arm 51, and a solenoid 52. One end of the first mounting arm 50 is fixed to the suction plate 15, and others. The solenoid 52 is fixed to the end. The solenoid 52 includes a plunger 53 that can move forward and backward, and the tip of the plunger 53 is attached to one end of the second attachment arm 51. The other end of the second attachment arm 51 is attached to the eccentric position of the cylinder 41 via the engagement pin 54, and supports the cylinder 41 in a rotatable manner. The stroke amount of the advance / retreat movement of the solenoid 52 with respect to the plunger 53 is controlled by the control unit 9, and the rotation angle of the cylinder 41 is adjusted by the stroke amount of the advance / retreat movement of the plunger 53. The position of the blowing hole 44 with respect to the sticking surface 35a is displaced, so that the spraying angle is adjusted.
Since a plurality of blowout holes 44 are provided in the vertical direction (from the front side to the back side in FIG. 4) with respect to the sticking surface 35a of the sticking object 35, air A can be sprayed over a wide range, The removal range can be expanded.
The cylinder 41 is attached in a state where it is retracted without protruding from the suction surface 15a of the suction plate 15 (upper side in FIG. 4). Therefore, the label piece 11 on the sticking surface 35a due to the approach of the suction plate 15 is attached. It does not get in the way of pasting.
Other configurations, operations, and effects are substantially the same as those of the previous embodiment, and detailed description thereof is omitted.

It should be noted that the configuration and operation of the above-described embodiment are examples, and it goes without saying that they can be changed as appropriate without departing from the spirit of the present invention.

    For example, in the above-described embodiment, as the pasting mechanism 7 for pasting the label piece 11 sucked and held on the label sucking board 15 to the pasting object 35, the contact type “label” for pasting the arm 20 of the moving mechanism 16 advanced. The “sticking device” has been described as an example, but the present invention is not limited to this. Of course, air is blown into the hollow portion 17 of the label suction plate 15 from a compressor (not shown), and the label piece 11 is stuck by air ejection. It may be a “labeling device”.

    In addition, as the object to be pasted 35, a folding box called “Oricon” in which the picked object is accommodated is assembled and the upper part is opened, or a lid that is repeatedly used for transporting fresh food, frozen products, etc. For convenience of explanation, the pasting mechanism 7 has been described as a horizontal type in which the label piece 11 is pasted on the pasting surface 35a on the lateral side surface of the article 35, but it is of course not limited to this. Even pasting from above is possible.

Furthermore, for the convenience of explanation, the label continuous body 2 has been described as a peeling type in which the label piece 11 is temporarily attached to the backing sheet 10, but the present invention is not limited to this. Instead of 5, it may be a “label sticking device” that uses a “cutter device” or the like to cut the label pieces and paste them.

It is the schematic explanatory drawing of the plane which looked at the label sticking apparatus of this invention from upper direction. It is an enlarged explanatory view of the angle adjusting means. The flowchart showing the labeling method, FIG. 4 is an enlarged explanatory view corresponding to FIG. 2 showing another embodiment of the angle adjusting means. FIG. 5 is a schematic perspective view as seen from the direction indicated by an arrow V in FIG. 4.
