Description

  The present invention relates to a label attaching apparatus and a label attaching method capable of attaching a label to an inner surface of a container or the like.

  In containers such as fragrances and deodorizers placed indoors, a mat that gives a frosted glass-like appearance by forming fine irregularities on the surface in order to make the internal chemicals difficult to see and improve the appearance. Processing may occur. In addition, such fragrances are required to be further improved in aesthetics because they are placed indoors and form part of the interior. It is considered to apply the applied label to the container.

  However, when a label is applied to the surface of a container that has been subjected to mat processing, the adhesive on the label enters the gaps between the fine irregularities on the surface of the container provided by the mat processing, so that the clearance is filled. And the effect of mat processing may be impaired.

In such a case, since the label is affixed to the container while maintaining the mat processing effect, the label may be affixed to the inner peripheral surface of the container that is not matted. As a label sticking apparatus capable of sticking such a label, one described in Patent Document 1 is known.
This device is provided so as to be insertable inside an adherend such as a container, and is provided on a sticking head provided so as to be relatively movable along the inner peripheral surface of the adherend, and on the sticking head, and an adhesive. A label holding unit that holds the label with the layer facing outside, and the label held by the label holding unit is attached to the inner peripheral surface of the adherend by relative movement between the adherend and the pasting head. .

  By the way, when a high aesthetic appearance is required for the container to which the label is attached as described above, the label is pressed without sag while pressing the label with a squeegee plate to eliminate air between the label and the adherend. A so-called squeegee technique is sometimes used.

  However, when trying to use the squeegee technique with the label sticking device described in Patent Document 1, a large force acts between the squeegee plate and the container, so that it is difficult for the container to rotate relative to the squeegee plate. Therefore, there is a problem that the label cannot be attached easily.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a label sticking apparatus and a label sticking method capable of sticking a label while maintaining a good aesthetic appearance on the inner peripheral surface of an adherend. To do.

  The label sticking device according to the first aspect of the present invention is a label sticking device for sticking a label to an inner peripheral surface of a cylindrical adherend having a bottom surface at one end, the adherend And a squeegee capable of entering the inner space of the adherend held by the adherend holding portion and capable of pressing the label toward the inner peripheral surface. The adherend holding portion has a fitting member formed so that one end thereof can be fitted to the bottom surface of the adherend, and the fitting member and the adherend are When the squeegee plate is pressing the label toward the inner peripheral surface of the adherend, the fitting is performed with the one end of the fitting member fitted to the bottom surface. The squeegee plate pushes the label by a frictional force generated between the one end of the member and the bottom surface. Characterized in that it is capable of relative rotation with respect to the squeegee plate while maintaining the state.

  According to the label sticking device of the present invention, the adherend is relatively rotated against the pressing force of the squeegee plate by the frictional force generated between the fitting member and the bottom surface of the adherend, while performing the squeegee. A label is affixed to the inner peripheral surface of the adherend.

  The label sticking device of the present invention may further include a stopper that is formed so as to be able to contact an end surface opposite to the bottom surface of the adherend and restricts movement of the adherend in the axial direction. In this case, the adherend is prevented from shaking in the axial direction when the label is applied, and the adherend is in contact with the stopper, so that the fitting member and the bottom surface of the adherend are easily brought into close contact with each other. A frictional force can be generated.

  The label sticking apparatus according to the first aspect of the present invention is a label sticking apparatus for sticking a label to the inner peripheral surface of a cylindrical adherend, and is a cover for holding the adherend. An adhering body holding portion, and a squeegee plate configured to be able to enter the internal space of the adherend held by the adherend holding portion and pressing the label toward the inner peripheral surface; The adherend holding portion is formed so as to be in contact with one end face of the adherend, and includes a stopper for restricting movement of the adherend in the axial direction, and the other end of the adherend. A pressing member that presses in the axial direction of the adherend and holds the adherend between the stopper and the stopper; and the adherend holding portion and the adherend include the squeegee. When the plate is pressing the label toward the inner peripheral surface of the adherend, the adherend is stopped by the stopper. Wherein in a state of being sandwiched and fixed between the pressing member, wherein said squeegee sheet is rotatable relative to the squeegee plate while maintaining the state of pressing the label.

  Also in the above-mentioned label sticking apparatus, the adherend sandwiched and fixed between the pressing member and the stopper against the pressing force of the squeegee plate is rotated relative to the squeegee plate together with the adherend holding portion, so that the squeegee A label is affixed to the inner peripheral surface of the adherend.

  The label sticking method according to the second aspect of the present invention is a label sticking method for sticking a label having an adhesive layer on the inner peripheral surface of a cylindrical adherend having a bottom at one end, An adherend holding step for holding the adherend with a predetermined force; a label entering step for causing the label to enter the inside of the adherend; and pressing the label toward the inner peripheral surface with a squeegee plate. The labeling step includes rotating the adherend relative to the squeegee plate around its axis, and sticking the label to the inner peripheral surface. The size is such that the adherend can be rotated relative to the pressing force of the squeegee plate.

  In the label sticking apparatus and the label sticking method described above, an adherend in which fine irregularities are formed on the outer peripheral surface by mat processing may be used. In this case, the aesthetic appearance of the adherend can be enhanced by applying the label to the inner peripheral surface without impairing the matting effect of the outer peripheral surface.

  According to the label sticking apparatus and the label sticking method of the present invention, the label can be stuck on the inner peripheral surface of the adherend while maintaining a good aesthetic appearance.

  A label sticking apparatus according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an overall perspective view of the label sticking device 1 of the present embodiment. The label sticking device 1 includes an adherend holding part 2 that holds an adherend to which a label is stuck, a label sticking part 3 for sticking a label to a peripheral surface that has not entered the adherend, A labeler 4 for supplying a label to the label attaching unit 3 is provided.

  FIG. 2 is a view showing a container 100 as an example of an adherend. The container 100 is for housing the fragrance 101 and is formed in a substantially cylindrical shape having a bottom surface 100A. The bottom surface 100 </ b> A is formed in a curved shape that gently protrudes toward the opening 100 </ b> B on the opposite side of the container 100 in the axial direction.

The container 100 is placed on the base 102 with the bottom surface 100A facing up, and the scent emitted from the fragrance 101 is diffused to the outside through a hole (not shown) provided in the container 100. The outer peripheral surface 100C of the container 100 is matted over the entire surface so that the contained fragrance 101 cannot be clearly seen, and has a frosted glass-like appearance due to fine irregularities.
In the following description, as an example in which the container 100 is used as the adherend, the adherend is replaced with the container 100.

  As shown in FIG. 1, the adherend holding unit 2 includes a storage unit 5 in which the container 100 is stored, and a cylinder (fitting member) 6 that can be fitted to the bottom surface of the container 100 stored in the storage unit 5. And a cylinder rotating mechanism 7 for rotating the cylinder 6 around the axis.

  FIG. 3 is an enlarged view showing the accommodating portion 5 and the cylinder 6. The container 5 includes a base 8 on which the container 100 is placed, a stopper 9 provided at one end of the base 8, and a fitting part 10 provided at the other end of the base 8. Yes.

The base 8 is a member formed in a substantially semi-cylindrical shape in which the cylinder is divided in half in the axial direction, and the container 100 can be stably installed in a state where the axis is horizontal.
The stopper 9 is formed in an annular shape at the end of the base 8 in the axial direction opposite to the cylinder 6. The stopper 9 abuts against the end surface of the container 100 placed on the base 8 on the opening 100B side, restricts the movement of the container 100 in the axial direction, and prevents the container from dropping from the base 8 or the like. The thickness of the stopper 9 in the radial direction is preferably set to be equal to or greater than the thickness of the outer peripheral surface 100 </ b> C of the container 100 from the viewpoint of satisfactorily contacting the end surface of the container 100.

  The fitting portion 10 is provided at an end portion of the base 8 on the cylinder 6 side in the axial direction, and includes a substantially circular end surface 10A and a side wall 10B extending from the periphery of the end surface 10A toward the base 8 side. . The fitting part 10 restricts the movement of the container 100 placed on the base 8 toward the cylinder. A through hole 10C is formed in the end face 10A, and the cylinder 6 can enter the accommodating portion 5 side through the through hole 10C.

The cylinder 6 is a rod-shaped member, and the tip thereof is formed in a convex curved surface corresponding to the bottom surface 100 </ b> A of the container 100. Therefore, when the cylinder that has entered the housing portion 5 comes into contact with the bottom surface 100A of the container 100, the two are fitted and a large frictional force can be generated between the two.
The cylinder rotation mechanism 7 has a drive mechanism such as a motor, and can rotate the cylinder 6 about its axis. The entire adherend holding unit 2 can be moved along the rail 11 shown in FIG. 1 by a moving mechanism (not shown), and the label attaching unit 3 enters the inside of the container 100 placed in the accommodating unit 5. Can be made.

The label sticking unit 3 includes a drum 12 that receives a label from the labeler 4 and a squeegee plate 13 that presses the label against the inner surface of the container 100 to perform a squeegee.
The drum 12 is formed in a substantially cylindrical shape with a part of a cylinder cut out, and can be rotated around an axis line by a drum rotating mechanism 14 including a motor or the like. The drum 12 and the drum rotating mechanism 14 are movable in the direction of the labeler 4 along a rail (not shown), approach the labeler 4, receive a label from the labeler 4, and wind it around its outer peripheral surface. This operation will be described later.

  The squeegee plate 13 is a plate-like member and can be moved in the vertical direction by a squeegee plate moving mechanism 15 including a cylinder and the like. By pressing the label against the inner surface of the container 100, a squeegee that removes air between the label and the container 100 is performed, and it is possible to apply the label while maintaining an aesthetic appearance. The squeegee plate 13 is preferably formed of a material that can be deformed to some extent, such as silicon rubber, so that the squeegee plate 13 can follow the inner shape of the container 100 and can be contacted without gaps.

  The labeler 4 has a known configuration, and can continuously supply the label while peeling off the backing paper of the label supplied from a roll (not shown) to expose the adhesive layer of the label.

The operation at the time of use of the label sticking device 1 configured as described above will be described.
FIG. 4 is a flowchart showing a flow of a label sticking method using the label sticking apparatus 1. First, in step S1, the user installs the container 100 as the adherend on the base 8 with the opening 100B facing the stopper 9 as shown in FIG. At this time, the bottom of the container 100 is fitted to the fitting portion 10 as necessary, the container 100 is held by the side wall 10B, and the container is attached so that label sticking is started from a predetermined position on the inner peripheral surface. You may perform positioning of 100 circumferential directions.

  Next, in step S2, the cylinder 6 enters the accommodating portion 5 side through the through hole 10C and comes into contact with the bottom surface 100A of the container 100 as shown in FIG. When the cylinder 6 further moves toward the accommodating portion 5, the end surface on the opening 100B side of the container 100 comes into contact with the stopper 9, as shown in FIG. In this state, the tip end surface of the cylinder 6 and the bottom surface 100A of the container 100 are fitted so as to be substantially coaxial and the container 100 is held with a predetermined force, and the axis X1 of the container 100 is held by the cylinder 6 and the stopper 9. The movement in the direction is restricted and positioned (adhered body holding step).

  In subsequent step S3, the label is supplied to the label pasting unit 3. First, in order to receive a label, the drum 12 moves from the initial state shown in FIG. 6A to the vicinity of the labeler 4 as shown in FIG. 6B. And the edge part of the label 105 is hold | maintained on the outer peripheral surface of the drum 12 by means, such as suction from the suction opening 12A, for example.

  When the drum rotating mechanism 14 rotates the drum 12 while holding the label 105, the label 105 is wound around the outer peripheral surface of the drum as shown in FIG. The wound label is sequentially held by suction or the like from the suction port 12A. At this time, the backing paper (not shown) of the label 105 is collected by the labeler 4, and the adhesive layer of the label 105 is exposed outside the drum 12. When the winding of the label 105 is completed, the drum 12 returns to the vicinity of the squeegee plate 13 and prepares for the subsequent process. Thereafter, the process proceeds to the label sticking step, but the above-described steps S1 and S2 and step S3 do not have to be performed in this order, and may be performed in the reverse order.

  Subsequently, in step S <b> 4, the adherend holding part 2 installed with the container 100 positioned is moved along the rail 11 toward the label sticking part 3. And the label sticking part 3 and the wound label 105 enter the space inside the container 100, and as shown in FIG. 7 (a), the label 100 can be put on the inner peripheral surface of the container 100 (label). Approach process).

  Then, after the adhesive layer at one end in the circumferential direction of the label 105 and the inner peripheral surface of the container 100 are bonded, the cylinder 6 and the container 100 are rotated, and one end of the bonded label 105 is attached to the squeegee plate 13 and the container 100. The position in the circumferential direction of the container 100 is adjusted so as to be located between the two. Since the adhesive force of the label 105 to the container 100 is stronger than the suction force of the drum 12, such position adjustment is possible. With this position adjustment, preparation for pressing the label 105 with the squeegee plate 13 is completed, and the process proceeds to step S5.

  In step S <b> 5, as shown in FIG. 7B, the squeegee plate moving mechanism 15 moves the squeegee plate 13 downward and presses the end of the label 105 against the inner peripheral surface of the container 100. Then, the adhesive layer of the label 105 comes into contact with the inner peripheral surface of the container 100, and the end portion of the label 105 is bonded to the inner peripheral surface of the container 100.

Furthermore, in step S6, the cylinder rotation mechanism 7 rotates the cylinder 6 in the direction of arrow A shown in FIG. 7B while releasing the suction and holding of the label 105 by the drum 12. As described above, since the cylinder 6 and the bottom surface 100A of the container 100 are fitted to each other, a large frictional force is generated between the cylinder 6 and the container 100 together with the cylinder 6 in the direction of arrow A, that is, the axis X1 of the container 100. Rotate around.
At this time, since the squeegee plate 13 presses the label 105 against the inner surface of the container 100, the adhesive layer is attached to the container 100 while the air between the label 105 and the container 100 is sequentially removed as the container 100 rotates. It is done. Thus, as shown in FIGS. 7C and 7D, the label 105 is squeezed and attached to the inner surface of the container 100 (label application step).

The force with which the squeegee plate 13 is pressed against the container 100 becomes a resistance when the cylinder 6 rotates the container 100. The cylinder 6 overcomes this resistance by the above-described large frictional force and causes the container 100 to squeeze around the axis X1. It can be rotated relative to the plate 13.
After completion of application of the label 105, the adherend holding unit 2 moves along the rail 11 so as to move away from the label application unit 3, and a series of operations ends.

  Due to the structure of the label applying part 3, the label 105 cannot be applied over the entire circumference of the inner peripheral surface of the container 100 in a single application process, but the same application process is performed several times while changing the application start position. Thus, a label can be attached while performing a squeegee over the entire inner peripheral surface of the container. Further, by adjusting the rotation angle of the cutout region of the substantially cylindrical drum, the range of the inner peripheral surface of the container where the label can be attached by a single attaching operation can be appropriately set.

According to the label sticking device 1 of the present embodiment, when the tip of the cylinder 6 is engaged with the bottom surface A of the container 100, a large frictional force is generated between the two. As a result, even if the squeegee plate 13 is pressed against the container 100, the resistance can be overcome and the container 100 can be relatively rotated around the axis X1, and a high aesthetic appearance can be achieved on the inner peripheral surface of the container 100 while performing squeegee. The label 105 can be stuck and held.
Therefore, even if it is an adherend like the container 100 whose outer peripheral surface 100C has been subjected to mat processing, a label with a design applied from the inside is applied without impairing the frosted glass-like appearance that the mat processing exposes. Thus, the beauty of the container 100 can be enhanced.

  Further, since the stopper 9 is provided at one end of the accommodating portion 5, the axial positioning is performed so that the container 100 is sandwiched between the cylinder 6 and the stopper 9. Accordingly, the container 100 does not shake in the axial direction during the application of the label 105 and does not fall from the base 8, and the label can be applied stably. The bottom surface 100A can be more closely attached to each other, and the frictional force generated between them can be increased.

Furthermore, since the fitting part 10 which can be fitted with the outer peripheral surface 100C of the container 100 is provided in the accommodating part 5, the fitting part 10 and the outer peripheral surface 100C are fitted, so that the circumferential direction of the container 100 is increased. It can install in the to-be-adhered body holding | maintenance part 2, positioning. Therefore, even if it is an adherend which needs to start label sticking from the specific position of the circumferential direction, it can install suitably and can stick a label.
5 (a) to 5 (c) show that the fitting portion 10 and the container 100 are disengaged as the cylinder 6 moves toward the accommodating portion 5 side. Since 6 is moving without rotating, this operation does not impair circumferential positioning. Further, by appropriately adjusting the protruding length of the side wall 10B toward the stopper 9 as necessary, the accommodating portion can be mounted so that the fitting portion 10 and the container 100 are not disengaged even if the cylinder 6 moves. It may be configured. In this way, the positioning of the container 100 in the circumferential direction can be further stabilized.

  Although one embodiment of the present invention has been described above, the technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the above-described embodiment, the example in which the adherend is rotated relative to the squeegee plate by rotating around the axis line has been described. Instead, by rotating the squeegee plate, The label sticking device of the present invention may be configured so that relative rotation is performed.

  Further, in the above-described embodiment, an example has been described in which the bottom surface of the adherend is a curved surface that is gradually convex toward the opening, and the tip of the cylinder is formed into a convex curved surface corresponding to the curved surface. However, this is only an example, and any other shape may be used as long as they can be fitted to each other.

  As a specific example, the periphery of the bottom surface of the adherend may protrude like a ceramic thread bottom, and the cylinder may be fitted inside the thread bottom. You may form in a bottom face and a cylinder, respectively. At this time, when the uneven shape is provided on the central axis of the adherend, the adherend can be rotated more favorably in a polygonal shape such as a triangle or a quadrangle than a circle.

  Further, in order to increase the frictional force generated between the cylinder and the adherend, the surface of the cylinder may be roughened by plasma treatment or the like. At this time, if the adherend is formed of a material that is easily damaged, a soft member such as a sponge is fixed to the tip of the cylinder so as to prevent the adherend from being damaged while increasing the frictional force. It may be configured.

  Furthermore, the holding method for relatively rotating the adherend against the pressing force of the squeegee plate is not limited to the fitting as in the above embodiment. As an example, the housing portion 5 is configured to be rotatable around the axis, and the adherend is sandwiched from both ends in the axial direction (for example, by a stopper 9 and a pressing member that presses from the bottom side) and held in the housing portion 5. The housing 5 and the held adherend may be rotated relative to the squeegee plate 13. In addition, the label sticking device of the present invention may be configured to hold or sandwich a portion other than the bottom surface, for example, the outer peripheral surface of the adherend, and relatively rotate the adherend.

Further, in the above-described embodiment, the description has been given using the container 100 whose outer peripheral surface is matted as an example of the adherend. However, the adherend is not limited to this, and has a bottom surface at one end. And what kind of adherend may be used if it is a substantially cylindrical thing with many ends opened. In addition, if the configuration in which the adherend is sandwiched and held in the accommodating portion as described above is adopted, even if the adherend is a cylindrical adherend that has no bottom and is open at both ends, the squeegee can be satisfactorily performed. Labeling can be performed.
In addition, if the squeegee plate can be moved up and down in small increments using a servo motor or the like, the label is pasted while squeezing the inner peripheral surface of another cylindrical adherend such as a triangular prism or quadrangular prism. It is also possible. In this case, if the adherend is rotated around the axis, the line extending in the height direction through the center of the cross-sectional shape orthogonal to the height direction of the cylindrical adherend is set as the above-mentioned axis. Good.
