FIG. 10 is a view for explaining another example of the path of the adhesive tape of the adhesive roll cleaner of the present invention.

In the present invention, after dust or dust adheres to the pressure-sensitive adhesive tape using the pressure-sensitive adhesive tape, the take-up shaft portion of the pressure-sensitive adhesive tape is rotated each time to wind the surface after use of the pressure-sensitive adhesive tape, and the pressure-sensitive adhesive tape. It is necessary to feed the unused adhesive surface of one end of the pivot shaft provided on the center axis of each end surface of the housing to one end of the pivot shaft. The shaft portion meshes and the pivot shaft portion on the other end side idles, and the pivot shaft portion on the other end side meshes and the pivot shaft portion on one end side rotates idle when the other rotation of the casing. A one-way clutch is used to transmit this rotation when the casing rotates in the direction in which the pivot shafts at the one end and the other end mesh with each other, and the winding shaft can be rotated by either one rotation or the other rotation of the casing. One end and the other end pivot shaft portion and the winding shaft portion for rotating the drive portion in the winding direction of the adhesive tape Provided between the further adhesive tape delivered from the delivery shaft portion, the opening in contact with the wound outermost surface direction substantially opposite to the direction of the adhesive tape which is located openings in the housing in the winding spool It was eliminated in the configuration and be Rukoto leading to.

  The adhesive roll cleaner of the present invention is stable in the direction in which the adhesive tape is transported in one direction and the delivery of the adhesive tape is stable and constant regardless of whether the casing is rotated forward or backward.

  Further, according to the present invention, in the above configuration, by providing the drive unit with a reduction gear, the adhesive tape is fed out and wound up behind the rotation of the casing. In other words, when the housing is rotated, the adhesive tape is sent out in one direction and wound up. However, since the conveyance of the adhesive tape is slower than the rotation of the housing, a large amount of dust and dust is deposited on the adhesive surface of the adhesive tape. Furthermore, consumption of the adhesive tape can be suppressed.

Further, according to the present invention, in the above configuration, the adhesive tape fed from the delivery shaft portion contacts the winding outermost peripheral surface of the adhesive tape in a direction substantially opposite to the direction in which the opening is located in the casing of the winding shaft portion. Therefore, the following effects can be obtained .

By doing as described above , the adhesive tape is loosened on the outer peripheral surface of the housing to create a gap and the usability is deteriorated, or excessively due to contact with the adhesive tape and dust or dust, for example, contact with the floor surface It is possible to prevent the adhesive tape from being sent out.

  Hereinafter, specific embodiments of the present invention will be described with reference to FIGS. 1 is an adhesive roll cleaner (hereinafter referred to as roll cleaner) of the present invention. The roll cleaner 1 is generally cylindrical and has a casing 2 having both end surfaces in the axial direction of the cylinder and an opening formed in the axial direction of the outer peripheral surface, and the casing 2.

  As shown in FIG. 8 (a), when the shaft cylinder 2a rotates in the direction indicated by the arrow (clockwise), the roller 2e is opposed to the biasing force of the spring 2d relative to this rotation, and the gentle gradient position of the clutch groove 2b. At this time, the roller 2e comes into contact with the shaft body 2d and tightens, whereby the shaft body 2d rotates together with the shaft cylinder 2a. On the other hand, as shown in FIG. 8B, when the shaft cylinder 2a rotates in the direction indicated by the arrow (counterclockwise), the roller 2e is relatively steeply positioned in the clutch groove 2b by the biasing force of the spring 2d. At this time, the roller 2e is separated from the shaft body 2d, and the shaft body 2d is idled with respect to the shaft cylinder 2a.

  For example, when the casing 2 is rotated forward, the pivot shaft 2A transmits rotational power, and the pivot shaft 2B does not transmit rotational power and rotates idle. 2 when the casing 2 rotates forward or reverse, such that the pivot shaft 2B transmits rotational power and the pivot shaft 2A rotates idly without transmitting rotational power. The rotary power is transmitted to the delivery shaft portion 3.

  In addition, the casing 2 has an opening 2C formed in the axial direction on the outer peripheral surface of the adhesive tape T that is fed out and wound up outside the casing 2, and the main body 2D and the cover section are formed with the opening 2C as a boundary.

The feed bearing portion 2f has a plastic spring structure having an arc shape with a part of the peripheral surface cut out. When the delivery shaft portion 3 is attached to the delivery bearing portion 2f, the diameter portion of the delivery shaft portion 3 is opened at the notch interval of the delivery bearing portion 2f, and is inserted into the inside of the delivery bearing portion 2f.

  Inside the main body 2D of the housing 2, in this example, the position where the winding shaft 4 is eccentric by a predetermined amount with respect to the pivot shafts 2A and 2B (centers of both end surfaces in the axial direction of the housing 2). Is provided. The winding shaft 4 has a drive unit 4A on the pivot shaft 2A side (FIGS. 4 and 6) of the housing 2 and a pivot shaft 2B side (FIGS. 5 and 7) on the housing 2. The drive unit 4B is provided so as to transmit both forward and reverse rotations of the housing 2 due to the intervening operation as forward rotation of the winding shaft portion 4 (rotation in the winding direction of the adhesive tape T). Yes.

  The drive unit 4A on the pivot shaft 2A side shown in FIGS. 4 and 6 is provided with a drive substrate 4Aa inside the main body 2D of the housing 2 (the end surface in the axial direction of the housing 2). A drive shaft 4Ab fitted into the take-up shaft portion 4 is provided integrally with the drive substrate 4Aa on the inner and outer sides of the drive substrate 4Aa.

  The drive shaft 4Ab on the outside of the drive board 4Aa is fitted with a spring 4Ac that is stretched with a natural length, and a drive gear 4Ad is provided at the end opposite to the drive board 4Aa. The drive gear 4Ad is meshed with the small-diameter side of the two-stage gear 4Ae having a small diameter and a large-diameter, and the large-diameter side of the two-stage gear 4Ae is meshed with a rotating gear 4Af provided on the shaft cylinder 2a of the pivot shaft 2A. ing. The two-stage gear 4Ae functions as a reduction gear.

  In addition, for example, when the adhesive tape T is loosened, the winding shaft 4 is forcibly rotated for adjustment without depending on the rotation of the pivot shaft 2A. An adjustment knob 4Ag is provided integrally.

  As shown in FIGS. 5 and 7, the drive unit 4 </ b> B on the side of the pivot shaft 2 </ b> B is provided with a drive substrate 4 </ b> Ba on the inner side of the main body 2 </ b> D of the housing 2 (end surface in the axial direction of the housing 2). A drive shaft 4Bb fitted into the take-up shaft portion 4 is provided integrally with the drive substrate 4Ba on the inner and outer sides of the drive substrate 4Ba.

  A drive shaft 4Bb protrudes outside the drive substrate 4Ba, and a cylindrical portion 4Bc centered on the drive shaft 4Bb is provided. Drive inner teeth 4Bd having the same inner diameter as the outer diameter of the drive gear 4Ad are formed on the inner peripheral surface of the cylinder portion 4Bc. The drive inner teeth 4Bd are meshed with the small diameter side of the small-diameter and large-diameter two-stage gear 4Be, and the large-diameter side of the two-stage gear 4Be is meshed with the rotating gear 4Bf provided on the shaft cylinder 2a of the pivot shaft 2B. doing. The two-stage gear 4Be functions as a reduction gear.

  Power is transmitted to the drive unit 4A on the pivot shaft 2A side and the drive unit 4B on the pivot shaft 2B side, for example, when the pivot shaft 2A and the pivot shaft 2B rotate in the power transmission direction, respectively. The drive unit 4A or the drive unit 4B on the other side is driven to rotate the winding shaft unit 4 in the winding direction of the adhesive tape T.

  Here, for example, the operation of the drive unit 4A and the drive unit 4B will be described with the pivot shaft 2A being the clockwise direction of the housing 2 and the pivot shaft 2B being the counterclockwise rotation of the housing 2. When the housing 2 rotates clockwise, the pivot shaft portion 2A transmits power, while the pivot shaft portion 2B is idling. When the housing 2 rotates counterclockwise, the pivot shaft 2B transmits power, while the pivot shaft 2A is idled.

  Thus, even if the housing 2 rotates forward and backward clockwise and counterclockwise, the winding shaft 4 can be correctly rotated in the winding direction of the adhesive tape T. 4Ad is a spur gear with teeth formed on the outer periphery, whereas the drive internal teeth 4Bd of the drive unit 4B are internal teeth with teeth formed on the inner periphery. This is because the winding shaft 4 is finally rotated forward.

  That is, when the casing 2 rotates clockwise, the pivot shaft 2A transmits the forward rotation through the rotation gear 4Af of the drive unit 4A (the pivot shaft 2B idles), and in sequence, the two-stage gear 4Ae. Is reversed, the drive gear 4Ad is rotated forward, and the winding shaft portion 4 is rotated forward in the winding direction. When the casing 2 is rotated counterclockwise, the pivot shaft 2B transmits the reverse rotation via the rotation gear 4Bf of the drive unit 4B (the pivot shaft 2A is idle), and the two-stage gear 4Be is forward. The drive and inner teeth 4Bd rotate forward, and the winding shaft portion 4 rotates forward in the winding direction.

  In the roll cleaner 1 of the present invention having the above-described configuration, the delivery shaft portion 3 and the take-up shaft portion 4 are refilled according to the procedure shown in FIG. First, after opening the cover portion 2E with respect to the main body portion 2D and removing the used delivery shaft portion 3 and the take-up shaft portion 4 from the housing 2, as shown in FIG. The portion 3 is pivotally supported by being fitted into the feed bearing portion 2f on the cover portion 2E side.

  Subsequently, one shaft end of the winding shaft portion 4 is fitted to the drive shaft 4Ab of the drive substrate 4Aa, and the drive substrate 4Aa is pushed outwardly against the biasing force of the spring 4Ac of the drive portion 4A, and the other end is opened. It fits on the drive shaft 4Bb of the drive board 4Ba. When the force for opening the drive board 4Aa to the outside is released, the drive boards 4Aa and 4Ba come close to each other by the biasing force of the spring 4Ac, and thus the winding shaft portion 4 is pivotally supported.

  Thereafter, the lead portion of the adhesive tape T is pulled out from the delivery shaft portion 3, and the roller 2Ca on the cover portion 2E side is wound around the outer peripheral surface of the housing 2 to make one round, and the roller 2Ca of the main body portion 2D. Is attached and the end portion of the lead portion of the adhesive tape T is affixed to the take-up shaft portion 4 or fixed, and then the cover portion 2E is closed as shown in FIG. 9B.

  After closing the cover portion 2E, as shown in FIG. 9C, the adjustment knob 4Ag is rotated to eliminate the slack of the adhesive tape T on the outer peripheral surface of the housing 2 and the refilling is completed.

  Moreover, the roll cleaner 1 is good also as a conveyance path | route of the adhesive tape T as shown in FIG. That is, the conveyance path of the adhesive tape T shown in FIG. 10 is such that the adhesive tape T delivered from the delivery shaft portion 3 is in a direction substantially opposite to the direction in which the opening 2C is located in the housing 2 of the take-up shaft portion 4. The adhesive tape T is stretched over the outermost circumferential surface of the adhesive tape T so as to reach the opening 2C. By doing so, loosening during use is less likely to occur.

  As described above, the roll cleaner 1 of the present invention does not require the user to be aware of the forward / reverse rotation of the housing 2 and does not require the user to take up or send out the adhesive tape T. Simple and easy to use.
