Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a label mounting apparatus applied when a thin label having heat shrinkability is wound around the outer periphery of a container or the like and mounted.

(Prior Art) Conventionally, as this type of label mounting apparatus, for example, there is an apparatus shown in FIG.

The apparatus is provided with a mounting table-shaped support 13e for mounting and supporting the container 8 so as to be rotatable on the outer peripheral side of the rotary drum 4e for adsorbing and transferring the label 2. In this apparatus, after the outer peripheral surface of the container 8 is attached to the one end portion 2A of the label 2 on the rotary drum 4e side via the adhesive, the label 2 can be wound around the outer peripheral surface by the rotating action of the container 8. The label winding work can be done automatically.

(Problems to be solved by the invention) However, in the above means, since the label 2 is wound around the container 8 only on the support 13e, it is practical. And caused the following problems.

That is, the container 8 is not a simple cylinder or column,
As shown in FIG. 10, when the upper and lower ends are formed as a shoulder portion 34a having a small diameter or a rounded corner portion 34, the body portion 8c of the container 8 extends over the shoulder portion 34a and the corner portion 34. Therefore, the label 2 cannot be wrapped neatly. In this type of label mounting work, when the label 2 is wrapped around the container 8, the label 2 may be pressed to the outer peripheral surface side of the container 8 by a soft member such as a sponge 33 in order to adjust the attached state.
Especially when the sponge 33 presses the shoulder 34a and the corner 34
The label portion facing to is folded to the side of the container and a large amount of wrinkles are generated. In this case, even if the upper and lower parts of the label 2 are subsequently heated and shrunk, the label 2 adheres to the container surface in a state where wrinkles remain, resulting in a problem that the appearance of the container becomes very bad.

The present applicant has developed, for example, a device disclosed in Japanese Patent Laid-Open No. 62-271820 as a means for appropriately winding a label on a curved container. This means is applicable after a plurality of pad plates 36 each having an adsorption hole capable of adsorbing and holding the label 2 are arranged on the outer periphery of the container 8 as shown in FIG. 11, and the label 2 is wound around the pad plates 36 ... It is a means for allowing the label 2 formed in a cylindrical shape as shown in FIG. 8B to remain on the outer periphery of the container 8 by lowering and retracting the vertical plates 36. However, with this means, the label 2 is only made into a cylindrical shape and is not wrapped around and adhered to the container 8, so that it can be applied only to the purpose of heat-shrinking the entire label and bringing it into close contact with the container surface. There are no difficulties. Also, in terms of the device configuration, it is necessary to prepare a plurality of pad plates 36 for adsorbing and holding the label 2 for one support 13e, which is an economic obstacle, and the above-mentioned conventional problems can be solved appropriately. I can't reach it.

Therefore, the present invention allows the label to be extended from the body of the label-attached object to the end even when the end of the label-attached object such as a container has an outer shape different from that of the body. Its purpose is to wrap it in a beautiful state without wrinkles so that it can be attached.

(Means for Solving the Problem) The present invention sets the end side of the label mounting target flush with the body side when the label mounting target is supported by the support, and then the label mounting is performed. The conventional problems described above are solved by wrapping the label on the end side of the object as well as on the body side.

That is, according to the first aspect of the present invention, the body 8c on the central side of the label mounting object 8 is exposed on the outer periphery of the tip of the support 13 for supporting and rotating the label mounting object 8. Is provided so that the projecting edge portion 24 can be freely inserted into and removed from the end portion 8a of the label attachment target formed to have a smaller diameter than the body portion 8c, and the outer diameter D of the projecting edge portion 24 is at least the projecting edge portion. The outer peripheral surface of the end side of the portion 24 is set to have the same or substantially the same diameter as the body portion 8c of the label mounting object 8 so as to be flush with the body portion 8c of the label mounting object 8, The label 2 is a label mounting device in which the label 2 is wound from the body portion 8c of the label mounting object 8 over the projecting edge portion 24 when the label mounting object is fitted to the end portion 8a.

Secondly, the present invention is based on the above-mentioned structure, in which the support 13 and the projecting edge portion are provided.
24 is formed as a separate body, and the support body 13 is positioned substantially flush with the mounting portion 32 on which the label mounting target 8 that is projected above the projecting edge portion 24 and that is supplied is mounted. So that the support
This is a label mounting device in which any one of 13 and the projecting edge portion 24 is provided so as to be capable of moving up and down in opposition to the other.

Thirdly, according to the present invention, in the label mounting apparatus having the above-mentioned second construction, the label mounting object 8 is provided with a side wall of the label mounting target 8 from the body 8c to the side of the position where the support 13 is arranged. The label mounting device is provided with a heating means (38) for heat-shrinking the label portion which is wound over the outer peripheral surface and is protruded from the body portion (8c) to the end portion side by retracting the protruding edge portion (24).

(Operation) In the label mounting apparatus having the above-described first configuration, when the label mounting target 8 is supported by the support 13, the projecting edge portion 24 is placed outside the small diameter end 8a of the label mounting target 8. By being fitted, the label 2 on the rotary drum 4 side can be simultaneously wound not only on the body portion 8c of the label attachment target 8 but also on the outer peripheral side of the projecting edge portion 24 on the end portion 8a side.

At least the outer circumference of the projecting edge 24 on the tip side is flush with the body 8c of the label attachment target 8, so the label portion wound around the end 8a is flush with the body 8c. As a result, the inside edge is not folded from the outer peripheral surface of the projecting edge portion 24, and wrinkles do not occur. Moreover, the adhered state of both ends of the label 2 is also ensured.

Further, in the label mounting apparatus having the second configuration, when the label mounting target 8 is placed and supported on the support 13, the label mounting target 8 projects from the support 13. In order to prevent the protruding edge portion 24 from being caught, the protruding edge portion 24 can be retracted from the tip surface of the support 13 to a non-projecting state.

Further, in the label mounting apparatus having the above-mentioned third configuration, the label mounting target 8 of the labels 2 wound around the body 8c of the label mounting target 8 from the outer periphery of the projecting edge 24 is The portion protruding to the end 8a side can be heated and shrunk by the heating means 38 while the label mounting target 8 is supported by the support 13. Therefore, after the protruding portion of the label 2 is contracted and brought into close contact with the end portion 8a of the label-attached object 8 so as not to easily be rolled up, the label-attached object 8 on which the label 2 is completely wound is Support 13
You can take it out from.

The inner periphery 25 of the tip of the projecting edge 24 is formed in a curved shape so that it can be fitted onto the rounded lower end 8a of the container 8, and the outer diameter D thereof is substantially the same as that of the body 8c at the center of the container 8. It is set to the same diameter. The support 13
Is constantly elastically urged by a spring 39 so as to be projected upward by the projecting edge portion 24 of the guide body 23.

Reference numeral 13a denotes a support member which is paired with the support member 13 to support the upper end portion 8b side of the container 8. The outer periphery of the tip end portion of the support member 13 is formed so as to be externally fitted to the small diameter stepped upper end portion 8b of the container 8. Edge 24

It is substantially the same as the body portion 8c. Reference numeral 31 is a rod for supporting the support body 13a, and is provided on a rotary plate 28 that rotates in conjunction with the rotary drum 4 so that the support body 13a can be revolved while being maintained above the lower support body 13. On the other hand, it is supported so that it can be raised and lowered and driven to rotate. Reference numeral 29 denotes a cam follower for raising and lowering the rod 31 and the support 13a at a predetermined timing by abutting on the plate cam 30. Among them, the above-mentioned pair of upper and lower supports 13, 13a are provided in a plurality of sets at appropriate intervals.

38 is a heating device which is arranged near the discharge device 12 and is set to be located on the side of the revolving movement position of the support body 13, and is a lower part of the label 2 wrapped with hot air or steam around the label attachment target 8. It is for spraying on the position.

The configuration of the apparatus according to the present embodiment is as described above. Next, its usage example and operation will be described.

First, the label 2 cut by the cutting unit 1 is adsorbed and held on the outer peripheral surface of the rotary drum 4, and an adhesive and a solvent are applied to both ends of the label 2 by the applicators 6, 6a and transferred. On the other hand, the pair of upper and lower supports 13, 13a revolves in synchronization with the rotating drum 4 while avoiding collision with the coating devices 6, 6a, etc., but when they reach the side of the supply device 7, As shown in FIG. 5 (a), the support 13 is raised to the same position as the mounting plate 32. This allows the container 8 to be transferred from the supply device 7 onto the support 13. However, at that time, since the support body 13 is raised above the projecting edge portion 24 of the guide body 23 by the elastic force of the spring 39,
The container 8 does not get caught at the projecting edge 24 and fall.

On the other hand, at the same time when the container 8 is transferred onto the support body 13, the support body 13a on the upper side is moved downward so that the projecting edge portion 24a is located at the upper end portion of the container 11.
Fit on 8b. The downward pressing force of the support body 13a causes the support body 13 to be lowered to a position lower than the projecting edge portion 24 against the elastic force of the spring 39. As a result, the projecting edge portion 24 protruding above the support 13 is fitted onto the lower end portion 8a of the container 8.

After the container 8 is supported by the upper and lower supports 13 and 13a as described above, the one end 2A of the label 2 on the rotary drum 4 side is attached to the outer peripheral surface of the container 8 with an adhesive while rotating the container 8. The label 2 is wrapped around the container 8 by the rotation action of the container 8 while being adhered and held therethrough. At that time, the label 2 is not limited to the body portion 8c of the container 8 as shown in FIG.
It is also wound around the outer circumferences of the projecting edge portions 24, 24a which are fitted onto the 8a, 8b.
However, the position of the adhesive applied to the label 2 should be considered in advance so that the label 2 is not firmly adhered to the projecting edge portions 24, 24a via the adhesive.

Since the outer circumferences of the projecting edges 24, 24a are flush with the body 8c of the container 8, the label 2 is neatly wound around the body 8c of the container 8. Further, even when the label 2 is pressed against the side surface of the container by the guide member 33 such as a sponge during the winding, the upper and lower edges of the label 2 are the projecting edge portions 24, 24a.
It does not fold inward to form wrinkles because it follows the.

The above-mentioned label winding operation is completed by adhering the final end portion 2B of the label 2 to the starting end side of the label 2 through a solvent. Part 24,2
Since it can be arranged along the outer periphery of 4a in order,
Adhesion of the superposed parts of 2A and 2B can be ensured.

After that, the container 8 on which the label is attached is discharged to the discharging device 12 side. First, the upper support 13a is raised as shown in FIG. This allows the lower support 13
Is raised by the urging force of the spring 39, and the projecting edge portion 24 is retracted from the upper surface of the support 13 to be in a non-projecting state. In this state, the lower portion of the label 2 protruding below the body portion 8c of the container 8 is not bonded to the rounded lower end portion 8a of the container 8. Therefore, if hot air or the like is blown from the heating device 38 to the lower portion of the label 2, the label portion is thermally contracted and the lower end portion 8a of the container 8 is
Close to the outer peripheral surface of. If this work is performed, it is possible to appropriately eliminate the fear that the lower portion of the label 2 will be curled when the label mounting target 8 is transferred onto the mounting plate 37 of the discharging device 12. Further, since the support 13 is above the projecting edge portion 24, the projecting edge portion 24 is not caught when the container 8 is transferred.

The label-equipped container 8 thus obtained may be heated and shrunk on the unshrinked portion of the label 2, that is, on the upper end side in the subsequent step, so as to be brought into close contact with the container surface. The label portion adhered to the body portion 8c of the container 8 does not need to be heated and shrunk. Therefore, the printing performed on the label of the body portion 8c does not shrink, and the appearance of the label can be further improved.

In the above embodiment, since the upper and lower ends of the label mounting target 8 are supported by the pair of upper and lower supports 13 and 13a having the projecting edges 24 and 24a, respectively, the label mounting target 8 is stabilized. In addition to suppressing the rotational runout, there is an advantage that the label 2 can be mounted by straddling both upper and lower end portions 8a and 8b of the label mounting target 8. However, the present invention is by no means limited to this.

For example, as shown in FIG. 6 (a), when it is not necessary to attach the label 2 to the upper end portion 8b side of the label attachment object 8, the protruding edge portion 24 may be provided on the lower support 13 as well. . In this case, the upper support 13a does not need to be externally fitted to the upper end of the label attachment target 8 and may be configured as a conventionally known support 13a to be fitted into the mouth of the label attachment target 8. Absent. On the contrary, as shown in FIG.
When it is not necessary to attach the label 2 to the lower end 8a side of the above, the protruding edge 24a may be provided only on the upper support 13a side.

Further, in the present invention, it is not always necessary to provide a pair of upper and lower supports for the label attachment target. For example, as shown in FIG. 7, the label mounting target 8 is supported only by the lower support 13,
Alternatively, the label attachment target 8 may be supported only by the upper support 13a. In the latter case, it is difficult to reliably support the label-attached object 8, but it is possible to provide the support 13a with a container fixing clamp means, a container suction holding air suction means, or the like. As described above, the present invention is applicable to supporting either the upper or lower end portion of the label attachment target 8. It should be noted that the specific mounting means, driving means, movement locus, etc. of the support are not limited to those in the above embodiment.

Further, in the present invention, regardless of the specific forming means of the projecting edge portion 24,
The projecting edge may be formed integrally with the support or separately. However, when the support 13 and the projecting edge portion 24 are separately configured and a means for moving them up and down relatively is applied, the projecting edge portion 24 is fixed and the support body 13 is fixed as in the above embodiment. As a matter of course, contrary to the means for raising and lowering, the supporting body 13 may be fixed to raise and lower the projecting edge portion 24. Further, these specific elevating means may be configured to elevate and lower the flange portion 24 or the support 13 at a predetermined timing by using, for example, a cam, instead of the means using the spring 39 as described above.

In the present invention, the specific shape and size of the projecting edge portion 24 may be arbitrarily changed according to the label attachment target 8. The present invention can be applied regardless of the shape of the end of the label-attached object 8 such as a rounded corner, shoulder, chamfer, step, or the like. It is not necessary to set the entire outer circumference of the projecting edge portion 24 to the same outer diameter as the body portion 8c of the label attachment target 8. For example, as shown in FIG. 8, only the predetermined portion L on the tip end side of the projecting edge portion 24 may have the same diameter D as the body portion 8c, and the diameter Da lower than that may be different. This is because, even in this case, the label 2 can be wrapped around the outer periphery of the projecting edge portion 24 on the front end side, and the label can be attached to a desired desired portion of the lower end portion 8a of the label attachment object 8.

In short, it is provided integrally or separately on the outer periphery of the tip end portion of the support body as a projecting edge portion that is externally fitted to the end portion 8a of the label attachment target object formed to have a smaller diameter than the body portion 8c of the label attachment object 8, The outer diameter may be set to have the same or substantially the same diameter as the body portion 8c so that at least the outer peripheral surface on the leading end side is flush with the body portion 8c of the label attachment target 8.

Further, the present invention is not limited to the concrete constitution of each part such as the rotary drum 4 as in the above-mentioned embodiment, and the rotary drum 4 is only required to adsorb and hold the desired label 2 and rotationally transfer it. Of course, the specific material of the label 2 and the presence / absence of printing or the like do not matter. As a matter of course, other than the label to which the adhesive is applied during the transfer on the rotary drum 4, for example, a label whose one side is previously applied with the adhesive may be peeled off from the release paper and used.

Other than the bottle container, other various articles such as spray cans, juice cans, and other containers can be applied as the label attachment target 8, and the specific type thereof is not limited.

(Effects of the Invention) As described above, the present invention is capable of being externally fitted to the end of the label-attached object and is flush with the body of the label-attached object on the support for rotating the label-attached object. By providing a projecting edge portion having an outer peripheral surface conforming to the state, the label transferred to the rotating drum is fitted not only on the body portion of the label mounting object but also on the end side of the label mounting object. Since the label can be wrapped around the outer periphery side of the label at the same time, the label is also wrapped around the outer periphery side of the projecting edge in a state of being flush with the body of the label attached target, and the label is attached to the label attached target as in the past. It does not cause folds and the like on the edge side to generate a large amount of wrinkles, and the label edge can be reliably bonded, so that the label wrinkles across the edge of the label attachment target with a different outer diameter. It can now be wrapped and installed in a beautiful condition without

Further, since the label having one end adhered via an adhesive can be directly wrapped around the outer peripheral surface of the body of the label-attached object supported by the support, the label should be adhered to the label-attached object. Can be installed tightly. In particular, when heat-shrinking a label, it is not necessary to interpose a backing plate between the label and the object to which the label is attached as in the conventional case, and the shrinkage error of the label can be reduced accordingly, and wrinkles and design of the label can be reduced. It is possible to effectively prevent distortion.

As a result, according to the present invention, the appearance of the article on which the label is attached can be made much better than before, and the product value can be improved.

Further, since the present invention only has the projecting edge portion formed on the support body for supporting the object to be attached with the label, the construction is very simple, and there is a merit that the manufacturing is easy and inexpensive.

Further, according to the means of the present invention, in which the support body and the projecting edge portion are separately formed, and one of the support body and the projecting edge portion is provided so as to be able to move up and down relative to the other, When the label-attached object is delivered, it is possible to prevent the protruding edge from being caught, and it is possible to obtain an effect that the transfer operation of the label-attached object can be made appropriate and easy.

Furthermore, according to the means for providing the heating means for heat-shrinking the label portion that causes the label mounting object to protrude from the body portion to the end side of the present invention, the label mounting object is supported by the support. In such a state, the protruding portion of the label can be brought into close contact with the end of the label attachment target, and when the label attachment target is subsequently handled, the end of the label may be inadvertently rolled up. It can be resolved in advance,
The excellent effect of being able to appropriately maintain the beautiful condition of label attachment is also obtained.

Moreover, as described above, the label can be tightly wrapped around the body of the label-attached object, so that when the label is heated and shrunk, only the upper and lower parts thereof can be shrunk to obtain sufficient adhesion. Therefore, it is possible to reduce the size and cost of the heating device.
