Description

  The present invention relates to a removed material removing apparatus for removing removed materials such as dust and adhesive.

  2. Description of the Related Art Conventionally, as a means for removing dust and pressure-sensitive adhesives, a remover called a “rolling roller” is used, which removes dust by rolling a surface coated with an adhesive material. In addition, a removal tool that removes an adhesive by bringing a tape wound around a reel into contact with an adherend by a transfer head is also considered (see, for example, Patent Document 1). These removal tools remove and collect dust and adhesives by moving the rollers and heads on the surface to which the dust and adhesives to be collected are attached.

  In addition, an apparatus that removes the pressure-sensitive adhesive attached to the movable body by transferring it to the transfer body is also considered (see, for example, Patent Document 2). In this apparatus, the tool belt and the transfer belt are rotated while the transfer belt is brought into contact with the tool belt to which the adhesive is adhered, whereby the adhesive adhered to the tool belt is transferred to the transfer belt and collected.

  2. Description of the Related Art In recent years, electronic paper that displays digital information on a thin display medium such as paper has started to spread as a display device that displays information. In electronic paper, a plurality of display electrodes are formed on an insulating substrate in a pattern corresponding to information to be displayed, and information display means whose color changes depending on the applied potential is arranged to face the display electrodes. Information is displayed by applying a potential to the information display means through the display electrode.

  In such a process of processing electronic paper, there is a process of removing the residue because of sticky residue generated in a part of the electronic paper. Therefore, it is conceivable to remove the residue in the same manner as the conventional technique described above.

  However, in the case of removing and collecting the removed object by moving it on the surface to which the removed object such as dust and adhesive to be collected is attached while contacting the roller or the head, when performing the work In addition, the adhesive tape must be brought into contact with the roller or head even in the area where there is no removed material, so an extra work space is required for rolling the roller or head, and the area where there is no removed material is adhered. There is a possibility that glue transfer may occur due to the tape, and it is difficult to control the amount of the adhesive tape fed out, which is not suitable for processing electronic paper.

  In addition, in the case of removing the adhesive adhered to the movable body by transferring it to the transfer body, in order to transfer the removed matter generated on a part of the electronic paper to the transfer body, the electronic paper itself is attached to a belt conveyor or the like. There is a problem that it is necessary to feed out using a mechanism, which causes the mechanism of the apparatus to be complicated and large.

  The present invention has been made in view of the problems of the conventional techniques as described above, and without making the apparatus complicated and large in size, the area where the removed object does not exist is soiled by glue transfer using an adhesive tape or the like. It is an object of the present invention to provide a removal object removing apparatus that can remove a removal object without any problem.

In order to achieve the above object, the present invention provides:
A holding portion for holding a continuous adhesive tape having an adhesive surface on at least one surface so as to be able to be drawn out;

  In the present invention configured as described above, a holding part that holds a continuous adhesive tape having an adhesive surface on at least one surface thereof so that it can be fed out, and an adhesive tape held in the holding part are rotated. Since the adhesive tape is wound around the head part so that the adhesive surface is on the outside, the removed part is pressed against the removed object. Adheres to the adhesive tape and is removed. Thereafter, when an operation for rotating the collecting unit to be collected is performed on the operation unit, the collecting unit is rotated in one direction by a predetermined angle by the driving unit. Then, the adhesive tape is collected in the collecting unit by an amount corresponding to the rotation angle of the collecting unit and is fed out from the holding unit, so that there is an area where the removed material of the adhesive tape is not attached to the head unit. Abut. And a removal part adheres to an adhesive tape and is removed by pressing a head part on another removal object again.

  In this way, after the removed object adheres to the adhesive tape and is removed by pressing the head portion against the removed object, the operation for rotating the recovery unit for collecting the adhesive tape is performed on the operation unit. Since the area where the removed object of the adhesive tape is not in contact with the part, there is no need to move the article such as a work table where the removed object exists, and the adhesive tape is attached to the area where the removed object does not exist. A removal thing can be removed, without making it contact | abut.

  In order to realize such a configuration, for example, the drive unit can rotate together with the recovery unit around a rotation shaft that cannot rotate itself, and can support the recovery unit and the operation unit. A rotation control shaft that rotates the rotating plate by the predetermined angle in accordance with the operation, and the collection unit is configured to be rotatable only in the one direction by a one-way clutch mechanism with respect to the rotation shaft. It is possible to do.

  Moreover, it is good also as a structure by which the rotation control shaft is urged | biased by the direction opposite to the direction which moves according to the said operation with a spring.

  According to the present invention, when the removal object adheres to the adhesive tape and is removed by pressing the head portion against the removal object, an operation for rotating the recovery unit that collects the adhesive tape is performed on the operation unit. The rotation control unit rotates the collection unit by a predetermined angle in one direction, and the adhesive tape is collected in the collection unit by an amount corresponding to the rotation angle of the collection unit and is fed out from the holding unit, whereby the head Since the area where the removed object of the adhesive tape is not in contact is in contact with the part, the removed object is then adhered to the adhesive tape and removed by pressing the head portion again against another removed object. Can do. Thereby, the removal object can be removed without making the apparatus complicated and large, and without contaminating a region where the removal object does not exist by glue transfer using an adhesive tape or the like.

It is a figure for demonstrating the rotation direction of the tape winding-up part shown in FIG.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram showing an embodiment of a removed object removing apparatus according to the present invention, where (a) is a diagram showing an internal configuration, and (b) is a configuration in which an adhesive tape 20 and a tape winding unit 40 are removed. FIG. FIG. 2 is a view showing a state in which the tape winding unit 40 and the gear plate 50 shown in FIG. 1 are attached.

  In this embodiment, as shown in FIG. 1, a holding unit 30, a tape winding unit 40 serving as a recovery unit, a gear plate 50 serving as a rotating plate, and a head roller 60 serving as a head unit are provided inside the housing 10. Are provided so as to be rotatable, and in addition, an operation unit 70 and a rotation control shaft 80 are provided. The gear plate 50 and the rotation control shaft 80 constitute a drive unit.

  A continuous adhesive tape 20 having an adhesive surface on one surface is wound and held in the holding portion 30 in a roll shape. The holding portion 30 is provided with a protrusion 31 on its circumference, and the adhesive tape 20 wound in a roll shape is fixed by the protrusion 31. The holding unit 30 has a rotation mechanism such as a bearing and is smoothly driven to rotate by the tension generated in the adhesive tape 20 as the tape winding unit 40 and the gear plate 50 are rotated. In addition, although it is possible to use the general thing which has an adhesive surface on one surface, the adhesive tape 20 may have an adhesive surface on both surfaces. In addition, it has a sufficient adhesive force to the removed object and has an adhesive force that does not have an adhesive force in a region other than the removed object with respect to a work table or the like that is in contact with the head roller 60. What it has is preferable.

  The tape take-up portion 40 is superimposed on the gear plate 50, and a hole 41 is formed at the center thereof, and a hole 42 is formed in a region away from the center. Further, the gear plate 50 has a hole 52 formed at the center thereof, and a projection 51 is provided in a region away from the center of the overlapping surface with the tape take-up portion 40. Then, the tape take-up portion 40 is superimposed on the gear plate 50 so that the gear plate 50 supports the tape take-up portion 40, and the gear plate 50 is placed in the hole 42 of the tape take-up portion 40 as shown in FIG. In the state where the projections 51 are fitted, the tape winding portion 40 and the holes 41 and 52 of the gear plate 50 are fitted with the rotation shaft 12 provided on the housing 10 which cannot rotate itself. The winding portion 40 and the gear plate 50 can rotate together with the rotation shaft 12 as a center.

  Further, one end of the adhesive tape 20 held by the holding unit 30 is fixed to the tape winding unit 40, and the tape winding unit 40 is held by rotating around the rotation shaft 12 together with the gear plate 50. A tension is generated on the adhesive tape 20 held by the part 30, and the adhesive tape 20 is drawn out from the holding part 30 and collected.

  The gear plate 50 is provided with a plurality of tooth portions 53 on the circumference thereof, and the rotation control shaft 80 is provided with a claw portion 81, and the tooth portion 53 and the claw portion 81 are engaged with each other. Thus, the gear plate 50 is configured to rotate as the rotation control shaft 80 moves.

  One end of the rotation control shaft 80 is provided with an operation unit 70 for moving the rotation control shaft 80 in the axial direction. Further, a spring fixing plate 72 a is attached to the rotation control shaft 80 in the vicinity of the operation unit 70, and a spring 71 is provided between the spring fixing plate 72 a and the spring fixing plate 72 b attached to the housing 10. ing. The rotation control shaft 80 is urged in the direction in which the operation unit 70 is attached by the restoring force of the spring 71. The spring fixing plate 72b is a hollow plate attached to the housing 10, and has a structure that fixes the spring 71 and does not obstruct the movement of the rotation control shaft 80.

  The head roller 60 is arranged such that a part of the head roller 60 is exposed to the outside from the opening 11 provided in the housing 10, and is configured to be rotatable by a rotation mechanism such as a bearing. Then, the pressure-sensitive adhesive tape 20 is wound around the holding portion 30 and the tape winding roller 40 so that the pressure-sensitive adhesive surface of the pressure-sensitive adhesive tape 20 is on the outside, thereby changing the direction of tension from the tape winding portion 40. While changing, it plays the role which makes the adhesive tape 20 track and adhere to a removal thing. At this time, if the removed object and the adhesive tape 20 are not sufficiently adhered, sufficient removal performance of the removed object cannot be exhibited. Therefore, the head roller 60 is softly pressurized with urethane rubber or the like to improve followability. It is desirable that the material can be deformed by. A roller 90 is provided between the head roller 60 and the tape winding unit 40.

  Below, operation | movement of the removal thing removal apparatus 1 comprised as mentioned above is demonstrated.

  FIG. 3 is a diagram for explaining the operation of the removed object removing apparatus 1 shown in FIG. In FIG. 3, the tape take-up portion 40 is shown in a transparent state for easy understanding. FIG. 4 is a diagram showing the relationship between the movement of the rotation control shaft 80 shown in FIG. 1 and the rotation of the gear plate 50. FIG. 5 is a diagram for explaining the rotation direction of the tape take-up unit 40 shown in FIG.

  For example, when removing the removed matter 2 generated in a part of the electronic paper 3 in the electronic paper processing step using the removed matter removing apparatus 1 configured as described above, first, as shown in FIG. As shown, after the head roller 60 is pressed against the removal object 2, the removal object removal apparatus 1 is lifted and separated from the electronic paper 3. Then, since the pressure-sensitive adhesive tape 20 held by the holding unit 30 is wrapped around the head roller 60 so that the pressure-sensitive adhesive surface is on the outside, the removed material 2 adheres to the pressure-sensitive adhesive tape 20 and the electronic paper 3 Stripped from.

  Next, the operation unit 70 is pressed as an operation for rotating the tape winding unit 40. Then, as shown in FIG. 3B, the spring 71 contracts and the rotation control shaft 80 moves downward in the figure. Since the claw portion 81 of the rotation control shaft 80 meshes with the tooth portion 53 of the gear plate 50, the gear plate 50 is centered on the rotation shaft 12 as shown in FIGS. 3 (b) and 4 (a). As shown in FIG. At this time, of the two spring fixing plates 72a and 72b fixing the spring 71, one spring fixing plate 72a is attached in the vicinity of the operating portion 70 of the rotation control shaft 80, and the other spring fixing plate. Since 72b is attached to the housing | casing 10, when the operation part 70 is pushed down, the space | interval of the two spring fixing plates 72a and 72b becomes narrow, and the spring 71 will shrink.

  Then, since the projection 51 of the gear plate 50 is fitted in the hole 42 of the tape winding unit 40, the tape winding unit 40 also rotates clockwise with the gear plate 50 about the rotation shaft 12 in the drawing. . At this time, the rotation control shaft 80 moves downward in the figure by a predetermined stroke amount by the operation unit 70 coming into contact with the housing 10 or by the length of the spring 71 in the most contracted state. . Thereby, the tape winding unit 40 rotates by an angle corresponding to the stroke amount that the rotation control shaft 80 has moved. For example, when the rotation control shaft 80 moves downward in the figure by the stroke amount of the length of the two claw portions 81, the tape take-up portion 40 has the length of the two tooth portions 53 on the circumference of the gear plate 50. It rotates by an angle according to the circumference.

  When the tape take-up unit 40 rotates, a tension is generated on the adhesive tape 20 that is pulled toward the tape take-up unit 40, whereby the holding unit 30 rotates counterclockwise in the figure and is held by the holding unit 30. The adhesive tape 20 is fed out of the holding unit 30 by an amount corresponding to the rotation angle of the tape winding unit 40 and the holding unit 30. Therefore, by adjusting the stroke amount that the rotation control shaft 80 moves when the operation unit 70 is pressed, the amount of the adhesive tape 20 fed out from the holding unit 30 can be set arbitrarily.

  When the adhesive tape 20 is unwound from the holding unit 30, the removed object 2 attached to the adhesive tape 20 moves from the area where the head roller 60 is pressed and is collected in the housing 10.

  Thereafter, when the operation to release and press the operation unit 70 is stopped, the rotation control shaft 80 is urged in the direction in which the operation unit 70 is attached by the restoring force of the spring 71, so that the operation unit 70 is pressed. Return to the initial position in the absence.

  At this time, as shown in FIG. 5, the tape take-up portion 40 has a part of the roller 43 exposed on the inner wall surface of the hole portion 41 in which the rotary shaft 12 is fitted, and the roller 43 is moved to the spring 44. Since the one-way clutch mechanism that is fixed by the rotation is provided, the rotation control shaft 80 will rotate counterclockwise (B direction) in the figure by returning to the initial position when the operation unit 70 is not pressed. Even if a force is applied through the gear plate 50, it does not rotate in that direction. Also in the gear plate 50, the projection 51 of the gear plate 50 is fitted in the hole 42 of the tape take-up portion 40, so that a force to rotate counterclockwise (B direction) in the drawing is applied. But it does not rotate in that direction. In the one-way clutch mechanism, the tape take-up portion 40 can be rotated clockwise (A direction) in the drawing, and therefore the tape take-up portion 40 of the tape take-up portion 40 accompanying the operation of pressing the operation portion 70 is enabled. Rotation is not regulated.

  Further, as shown in FIG. 4B, due to the inclination of the tooth portion 53 of the gear plate 50 and the claw portion 81 of the rotation control shaft 80, the force accompanying the upward movement of the rotation control shaft 80 causes the winding portion to move. Therefore, the gear plate 50 does not rotate.

  Thereby, as shown in FIG.3 (c), only the rotation control shaft 80, with the holding unit 30, the gear plate 50, and the tape winding unit 40 being in the state when the operation unit 70 is pressed, It will return to the position where the operation part 70 is not pressed down, and it will be prevented that the adhesive tape 20 is conveyed in the direction opposite to the direction which is drawn out from the holding | maintenance part 30. FIG.

  In this state, the removed object 2 attached to the adhesive tape 20 has moved from the area where the head roller 60 is pressed, and the removed object 2 of the adhesive tape 20 is not attached to the area where the head roller 60 is pressed. Since the region is in contact, the head roller 60 is again pressed against another removed matter generated in a part of the electronic paper 3 so that the removed matter is attached to the adhesive tape 20 and removed in the same manner as described above. can do.

  In this way, after the removed object 2 is attached to and removed from the adhesive tape 20 by pressing the head roller 60 against the removed object 2, an operation unit is used to rotate the tape winding unit 40 that collects the adhesive tape 20. When 70 is pressed, the area where the removed product 2 of the adhesive tape 20 is not in contact with the head roller 60 comes into contact, so there is no need to move the electronic paper 3 on which the removed product 2 exists, The removed product 2 can be removed without bringing the adhesive tape 20 into contact with the region where the removed product 2 does not exist.
