Description

  The present invention relates to a transfer tool capable of uniformly transferring a transfer medium onto a curved transfer target.

  A transfer tool for transferring an adhesive transfer medium, a white transfer medium, or the like to a transfer medium such as paper, a transfer unit for sending out a long belt-like substrate coated with the transfer medium, and a transfer medium to the transfer medium The take-up unit that winds up the substrate after transferring the material, and the substrate coated with the transfer medium are sent out from the sending unit, the transfer medium is transferred to the transfer target, and the transferred substrate is sent to the take-up unit A transfer section is provided.

  The transfer section is roughly divided into a tongue-shaped type that is substantially plate-shaped and a roller-type that rotates with the feeding of the base material. It was set as the structure which is not elastically deformed in the direction orthogonal to a surface.

  The transfer portion having the above-described configuration is transferred to a curved transfer target, for example, a transfer target having a shape in which the central part of the base in the width direction (hereinafter simply referred to as the width direction) is raised at the tip of the transfer part. When a medium is transferred, the central part in the width direction of the substrate can be transferred, but there is a problem that both end parts thereof are lifted without being transferred.

Therefore, in Patent Document 1 below, a notch is formed in the conveyance direction of the substrate in the width direction of the transfer portion, and the tip of the tongue-shaped transfer portion has a comb-like shape, and the comb teeth are individually independent. An elastically deforming configuration is disclosed.
JP-A-2005-59241

  However, since the structure of the transfer portion disclosed in Patent Document 1 has a configuration in which individual comb teeth are elastically deformed independently, the following problems have occurred. That is, when the transfer medium is transferred to the curved transfer target, the tip of each comb tooth causes a wrinkle on the transfer medium through the base material, and in particular, a white transfer medium (for correction) There is a problem that the state after transfer becomes cracked and ugly.

  Further, in Patent Document 1, when a foreign object is caught between comb teeth, some of the comb teeth are constantly elastically deformed, and as a result, the transfer medium is transferred to a planar transfer target. There is a problem that even in the case of performing the transfer, the entire region in the width direction cannot be uniformly transferred.

  The problem to be solved by the present invention is that, in the comb-shaped transfer portion structure in Patent Document 1, the transfer teeth after the transfer are cracked due to the individual elastic deformation of the comb teeth. In addition, there is a need to eliminate the possibility that the transfer medium cannot be uniformly transferred to a planar transfer target.

In order to solve the above problems, the transfer tool of the present invention is configured such that the tip of the transfer portion that is pressed against the transfer object during use is integrated with the entire width direction of the tip by the stress from the transfer target. The most characteristic feature is that the body is elastically deformed to follow the shape of the body and the following is further adopted .

That is , the transfer tool according to the present invention is characterized in that, in addition to the above-described configuration, the hardness of the tip of the transfer portion is increased stepwise from the widthwise central portion toward the widthwise both ends, or the use of the transfer portion. In some cases, a deformation prohibiting member is provided on the side opposite to the side that is sometimes pressed against the transfer target, which can be moved toward and away from the transfer portion .

Furthermore, in the transfer tool of the present invention , in the above, a plurality of cutout portions are formed in a direction perpendicular to the width direction at the front end portion of the transfer portion, and a portion where the cutout portion is formed and a portion where the cutout portion is not formed are continuous. As a configuration having a plurality of transfer portions, the transfer portion distal end portions are spaced apart from each other at a predetermined angle, and the respective arm portions connected to the respective base end portions of the transfer portions are assembled, It is good also as a structure which penetrated the axis | shaft pivotally supported by a housing | casing in the gathering location of these arm parts.

  In the transfer tool of the present invention, the tip of the transfer portion is elastically deformed in accordance with the shape of the transferred body, and the entire width of the tip is integrally deformed by the stress from the transferred body. For example, when a white transfer medium is used, it does not crack.

  Further, the transfer tool according to the present invention is such that the front end portion of the transfer portion is integrally deformed, so that a part of the width direction does not remain elastically deformed constantly, and therefore, the transfer medium is placed on a flat transfer target. The transfer medium can be reliably transferred uniformly in the width direction even when transferring the toner.

  Furthermore, the transfer tool of the present invention has a configuration in which a deformation inhibiting member that can approach and separate toward the transfer portion is provided on the side opposite to the tip portion of the transfer portion that is pressed against the transfer object during use, or has a plurality of transfer portions. If it is a structure, the deformation | transformation state of a transcription | transfer part can be properly used suitably according to the time of curved surface transfer and flat transfer.

  The present invention can be implemented by the following embodiments shown in FIGS. In the following description, since the transfer tool has the following configuration in common, illustration and description are omitted. The transfer tool partially transfers the transfer medium to the transfer target body through a shaft-shaped delivery unit in which a base material coated with a transfer medium is wound and a transfer unit 1 described later, in a housing P shown in the figure. A shaft-shaped winding unit that winds up the subsequent substrate. The transfer medium used for the transfer tool having the above-described configuration may be either a white material for correction, or an adhesive material that adheres the transfer object and the adherend.

  In the transfer tool configured as described above, the transfer unit 1 appropriately indicates a tongue type and a roller type in the following description. Here, the structure about each transfer part 1 of a tongue type and a roller type is demonstrated.

  In the roller type, the shaft 1a is pivotally supported at the front end of the housing P, and a transfer material 1b made of elastically deformable resin or rubber is provided on the outer periphery of the shaft 1a. And the case where the shaft 1a and the transfer material 1b are integrated with the same material or the transfer material 1b is omitted. In the roller type, the shaft 1a is elastically deformed following the curved surface of the transferred body in the former configuration, and the whole is elastically deformed following the curved surface of the transferred body in the latter configuration.

  On the other hand, the tongue-shaped type is provided with a tongue piece 1c having a substantially triangular or rectangular cross section cut at the center in the width direction, and provided at both ends of the tongue piece 1c in the width direction, and the derailment of the base material from the tongue piece 1c. And a guide wall 1d having a function of preventing or the like, and the guide wall 1d is provided at the tip of the housing P. The fact that the guide wall 1d is provided at the tip of the housing P has an important meaning in the later configuration.

(First form)
1 to 3 show a first embodiment of the present invention. In the first embodiment, the basic configuration of the following second to fifth embodiments is shown. In the roller-type transfer unit 1 shown in FIG. 1, the shaft 1a is softer than that used in a general transfer tool, that is, it is not elastically deformed at all or hardly. Moreover, since the transfer material 1b employs, for example, a nylon tube as a material, elastic deformation of the shaft 1a is not hindered.

  In the tongue-shaped transfer unit 1 shown in FIG. 2, the tongue piece 1c is softer than that used in a general transfer tool, that is, it is not elastically deformed at all or hardly.

  Conventionally, POM and ABS are mainly used as the material of the members corresponding to the shaft 1a and the tongue piece 1c, and these materials are not elastically deformed by the size when used in the transfer tool and the load during use. .

  On the other hand, the present invention is softer by at least 30% or more than the conventional one that is made of, for example, a material that is changed or is not elastically deformed, for example, based on the dimensions used in the transfer tool and the load at the time of use. The hardness is low), that is, the hardness is such that elastic deformation is easy and elastic recovery is guaranteed. For example, polyethylene or polypropylene may be used as the material.

  Incidentally, in the first embodiment, the material of the shaft 1a and the tongue piece 1c is low density polyethylene. This low density polyethylene has a Shore D hardness (ASTM D1706) of 48. The transfer material 1b uses a nylon tube as described above.

  The transfer unit 1 of the roller type shown in FIG. 1 and the tongue-like type shown in FIG. 2 presses the transfer unit 1 against the transfer target during transfer when transferring the transfer medium to the transfer target having a curved shape. As shown in FIGS. 3A and 3B, the shaft 1a and the transfer material 1b and the tongue piece 1c are elastically deformed along the curved surface, respectively, due to the stress from the transferred material.

  Therefore, the transfer medium is uniformly transferred without floating in the width direction. Further, in the transfer unit 1 of the present invention, the shaft 1a (and the transfer material 1b) and the tongue piece 1c are integrally deformed in the width direction, and the transfer medium is wrinkled by the tip of the comb teeth as in Patent Document 1 described above. Therefore, when the transfer medium is transferred to a curved transfer target, the transfer medium is not cracked.

  Incidentally, although not shown, when the transfer medium is transferred to a flat transfer target, the shaft 1a (and the transfer material 1b) and the tongue piece 1c have a width if the transfer portion 1 is in the transfer tool of the present invention. Since the part of the comb teeth is not constantly elastically deformed as in Patent Document 1, the transfer medium can be reliably transferred uniformly in the width direction. .

  Here, the relationship between the guide wall 1d and the housing P in the tongue-shaped transfer unit 1 shown in FIG. 2 will be described. Normally, in a general transfer tool, the casing P is provided with a side opposite to the front end, that is, the rear end of the tongue piece 1c that is pressed against the transfer target.

  In short, a general transfer tool is easily bent in a direction perpendicular to the surface of the tongue piece 1c because the guide wall 1d is not provided in the housing P. This bending prevents the so-called “one-sided contact” that the transfer medium is transferred only on one side in the width direction and the other side is not transferred when a non-uniform force is applied in the width direction during operation of the transfer tool. There is.

  In other words, the function of preventing contact by one piece due to the bending is due to the ability to absorb uneven pressing force during operation. However, in the present invention, when such bending occurs, the effect of the configuration in which the tongue piece 1c is elastically deformed is reduced.

  Therefore, in the transfer tool having the tongue-shaped transfer portion 1 of the present invention, the guide wall 1d, that is, both sides of the tongue piece 1c in the width direction are provided in the housing P, and the transfer portion 1 itself is the surface of the tongue piece 1c. Therefore, it is not easily bent in a direction perpendicular to the direction. Incidentally, in the case of the roller type, since the shaft 1a is pivotally supported by the housing P, the same effect as that in which the guide wall 1d is connected to the housing P is obtained.

  Note that the transfer tool of the present invention does not cause a single contact because the transfer portion 1 itself does not bend in a direction perpendicular to the surface of the tongue piece 1c. This is because the piece contact is caused by the non-uniformity of the force in the width direction, but such non-uniformity of the force is absorbed by the transfer part 1 that is elastically deformed in the transfer tool of the present invention.

  In other words, the transfer tool of the present invention can uniformly transfer the transfer medium to the curved transfer target in the width direction, and can be used to transfer the transfer medium to the flat or curved transfer target. Even if this non-uniformity occurs, the transfer medium can be uniformly transferred in the width direction without causing any contact with each other.

(Modification of the first embodiment)
FIG. 4 shows a modification of the roller type transfer unit 1 in the first embodiment. In the modification, the tip shape of the shaft 1a shown in FIG. 1 is a triangular pyramid. Thereby, when the transfer part 1 is elastically deformed, even if the shaft 1a is decentered, the rotation is not hindered, and the base material can be fed and wound smoothly. Further, it becomes easy to transfer the transfer medium in a meandering manner on a flat transfer target.

(Second form)
The second form shown in FIG. 5 is the width direction of the shaft 1a (FIG. 5 (a)) for the roller type and the tongue piece 1c (FIG. 5 (b)) for the tongue type in the transfer section 1 of the first form . The hardness is increased stepwise (for example, two steps in the figure) from the center to the both ends.

  Incidentally, in the second embodiment, low-density polyethylene was adopted in the soft portions of the shaft 1a and the tongue piece 1c. This low density polyethylene has a Shore D hardness (ASTM D1706) of 48. POM was adopted in the hard part of the shaft 1a and the tongue piece 1c. This POM has a Rockwell R hardness (ASTM D785) of 120. The transfer material 1b uses a nylon tube as described above. By doing in this way, compared with the effect in the said 1st form, it can come to be elastically deformed still more appropriately.

(Third form)
The third embodiment shown in FIGS. 6 and 7 is a configuration in which a plurality of notches 1e are formed in the direction perpendicular to the width direction on the transfer material 1b and the tongue piece 1c in the configuration of the second embodiment . At this time, the transfer material 1b and the tongue piece 1c are not divided by the cutout portion 1e, and are integrated as a whole, that is, the portion of the cutout portion 1e and the portion of the cutout portion 1e are continuous. By doing in this way, like the patent document 1, it becomes easy to elastically deform the transfer material 1b and the tongue piece 1c without causing the trouble caused by the comb teeth being independent.

(4th form)
Fourth embodiment shown in FIGS. 8 and 9, in the configuration of the first embodiment, the transfer unit 1, on the opposite side to the side of pressing at the time of use to a transfer member, toward and away from possible variations prohibition against the transfer section 1 In this configuration, the member 2 is provided. The deformation prohibiting member 2 will be described below separately for a roller type and a tongue type.

  In the case of the roller type shown in FIG. 8, the deformation prohibiting member 2 has, for example, a shaft shape, and is hard enough not to be easily elastically deformed as compared with the shaft 1a and the transfer material 1b. The deformation prohibiting member 2 is in contact with and separated from the transfer material 1b, and is composed of, for example, a small diameter shaft 2a and a large diameter shaft 2b, and the difference in hardness (softness) is not limited. Thus, it is necessary to set the hardness to a level that prohibits elastic deformation of the shaft 1a (and the transfer material 1b).

  The small-diameter shaft 2a is pivotally supported by a guide hole Pa formed at the tip of the housing P. In this example, the guide hole Pa is, for example, U-shaped with the open side upward. When the small-diameter shaft 2a is located on the shaft 1a side of the opposing vertical sides of the guide hole Pa, the large-diameter portion 2b is in contact with the transfer material 1b and elastic deformation is prohibited, and the small-diameter shaft 2a is separated from the shaft 1a. When positioned on the separated side, the large-diameter portion 2b is separated from the transfer material 1b and is in a state of allowing elastic deformation.

  If the guide hole Pa is formed in a U shape with the open side upward, when the small-diameter shaft 2a is moved so as to be selectively used between a state in which elastic deformation is prohibited and a state in which it is allowed to be used, The movement of the small diameter shaft 2a (deformation prohibiting member 2) can be prohibited.

  In the case of the tongue-shaped type shown in FIG. 9, the deformation inhibiting member 2 is, for example, plate-shaped, and is hard enough not to be easily elastically deformed compared to the tongue piece 1c. This deformation prohibiting member 2 is in contact with and separated from the upper surface of the tongue piece 1c, and has a plate member 2c and shaft portions 2d on both side surfaces in the width direction at two positions perpendicular to the width direction of the plate member 2c. ing.

  The shaft portion 2d is pivotally supported by a guide hole Pa formed on the upper surface side of the tongue piece 1c in the guide wall 1d. In this example, the guide hole Pa is formed, for example, with a front end of the straight line portion and a downward-facing path at the front end and the middle part of the rear end, and a straight line parallel to the straight line portion after the lower path. Each path is formed. A slightly narrow portion is formed to lock the shaft 2d immediately before the front end of each linear path of the guide hole Pa and at the rear end of the linear portion.

  By configuring the guide hole Pa in this way, when the shaft portion 2d is moved so as to be selectively used between a state where the elastic deformation is prohibited and a state where the elastic deformation is allowed, the shaft portion 2d (deformation prohibiting member) from each of these positions is moved. The movement of 2) can be prohibited.

  That is, when the shaft 2d passes through the narrow portion and is positioned at the front end of the linear path, the plate 2c is in contact with the upper surface of the tongue piece 1c, and elastic deformation is prohibited. Passes through the narrow portion and is positioned at the rear end of the straight portion in the guide hole Pa, the plate member 2c is separated from the upper surface of the tongue piece 1c, and the elastic deformation is allowed.

  As described above, when the deformation prohibiting member 2 is provided, the elastic deformation can be surely prohibited when the transfer unit 1 does not particularly need to be elastically deformed, and the operator can arbitrarily use it. Become. In addition, when it is comprised so that the distance of the approach / separation of the deformation | transformation prohibition member 2 with respect to the transfer material 1b and the tongue piece 1c can be changed in steps, it becomes possible to perform delicate adjustment of the elastic deformation amount.

(5th form)
The fifth embodiment shown in FIG. 10 has a configuration having a plurality of transfer sections 1 of the second to third embodiments . That is, the transfer tool in the fifth embodiment has a plurality of transfer portions 1 (described later), and these transfer portions 1 are spaced apart from each other by a predetermined angle. In the case of the type, the arm portions 3 provided on the guide wall 1d are gathered from the respective transfer portions 1 at one place, and the shaft 3a pivotally supported by the housing P is inserted into the gathering place of the arm portions 3. The transfer tool according to the fifth embodiment is used by rotating the transfer unit 1 around the shaft 3a so that the intended transfer unit 1 is at the use position.

  For example, as shown in FIG. 10A, the plurality of transfer sections 1 are roller-type transfer sections 1 and 1 having different hardness (softness), or one of which is elastically deformed, and the other is elastically deformed. Transfer part 1, a tongue-shaped transfer part 1, 1 having different hardness (softness) as shown in FIG. 10B, or one transfer part 1 that is elastically deformed, and the other transfer part 1 that is not elastically deformed. It is good.

  Further, for example, as the plurality of transfer units 1, as shown in FIG. 10C, a roller type and a tongue type transfer unit 1 are used, one of which is elastically deformed and the other is a non-elastically deformable transfer unit. 10, or as shown in FIG. 10D, the three transfer portions 1 may be appropriately mixed with the above-described FIGS. 10A to 10C.

  At this time, as described above, the arm 3 pivotally supports the shaft 1a in the case of the roller type, and is provided on the guide wall 1d in the case of the tongue type, and in any case, the shaft 1a (transfer material 1b) and Since the arm portion 3 itself is not easily bent and the arm portion 3 does not absorb the stress with which the transfer portion 1 can be elastically deformed because it is located at both ends in the width direction of the tongue piece 1c. The transfer portion 1 (which elastically deforms) surely deforms following the surface of the transfer target.

  In addition, when employ | adopting a 4th form for a 5th form, what is necessary is just to form the guide hole Pa which penetrates the above-mentioned small diameter shaft 2a in the surface of the arm part 3 which opposes, for example in the case of a roller type. Incidentally, in the case of the tongue type, since the guide hole Pa is formed in the guide wall 1d, the arm portion 3 does not interfere with the configuration.
