The rubbish attached thereto can be reused by washing the roller body.

The applicant of the present patent application is the inventor of the adhesive roller type cleaning tool (Japanese Reissue No. 2014/058006), which is a cleaning tool using an adhesive tape type roller, by which a roller body will be used. The drawn adhesive tape is taken up and placed in another roller body to eliminate the need to separate and remove the adhesive tape that has lost adhesion at the end of use.

The disclosed invention is a structure in which a pair of roller bodies are connected in a plurality of gears to rotate both of them, and when the cleaning tool is used, the gears are engaged by the pressing force from the gripping portion, thereby causing both roller bodies The other roller body that rotates integrally and rotates in response to the rotation recovers the used portion of the adhesive tape, and when it is not in use, it is a structure that releases the gear teeth.

However, in this configuration, when the used portion of the adhesive tape is taken up by the other roller body, the amount of winding of the tape body may cause a difference in the rotational speed of the pair of roller bodies. If the structure for compensating for the difference in rotational speed is not added, there is a problem that the winding and feeding of the adhesive tape cannot be balanced. Further, there is a problem that the structure is complicated in order to loosen the gears or to cancel the toothing as needed, and it is troublesome in repairing at the time of failure.

Here, it has been desired to develop an adhesive roller type cleaning tool equipped with a mechanism capable of compensating for the difference in rotational speed of a pair of roller bodies, and which is not easily broken, and which is easy to repair in case of failure, and which is easy to use.

Fig. 3 is a view showing the internal structure of an adhesive roller type cleaning tool using a pulley.

As shown in Fig. 1, the adhesive roller cleaning tool 1 of the present invention comprises: an adhesive roller unit 100 of an adhesive tape, a winding unit 200, a rotation operation transmitting unit 300, a main body 400, and a grip portion 410. By holding the grip portion 410 by the user, the main body 400 is moved back and forth by the grip portion 410, and the stock roller portion 100 is rotated in contact with the object to be cleaned, and dust such as dust is attached to the adhesive tape 10a for cleaning. The rotation force of the storage roller unit 100 is transmitted to the winding unit 200 via the rotation operation transmitting unit 300, whereby the winding unit 200 pulls out the dust from the storage roller unit 100 and adheres to dust or the like. The adhesive tape 10b is taken up and recovered.

The stocker roller unit 100 is a member for feeding or winding the adhesive sheet 10a that is wound up in a tubular shape, and is rotatably disposed in the body 400 as shown in FIG. structure. In the present embodiment, the adhesive sheet 10a is configured to be wound in a hollow core member formed of a cylindrical shape in advance, and is stored in a standby state, and the rod portion of the storage roller portion 100 is inserted. The hollow tubular member has a structure in which the front and rear are free to rotate. It is preferable that the storage roller unit 100 is provided with a locking mechanism for preventing the hollow core member in which the adhesive sheet 10a is wound from being detached from the rod portion.

The winding unit 200 is a member for winding and collecting the adhesive sheet 10b in a state in which the adhesive sheet 10b is taken out from the stocking roller unit 100 and is used in a state in which the dust is removed. Further, as shown in FIG. 1, the structure is provided to the main body 400 so as to be rotatable forward and backward. In the present embodiment, the winding portion 200 composed of the rod-shaped member is inserted into the hollow core member, and the adhesive sheet 10b to which the garbage has been collected and collected is taken up and collected in the core member. Further, it is preferable that the winding portion 200 is provided with a locking mechanism for preventing the hollow core member of the adhesive sheet 10b from being detached.

The rotation operation transmitting unit 300 is a member for transmitting the front and rear rotation of the storage roller unit 100 to the winding unit 200. In the present embodiment, the rotation operation transmitting unit 300 is configured to use a gear or a pulley as described later, and the storage roller unit 100 and the winding unit 200 are kept in a continuous state at all times. Thereby, when the storage roller unit 100 rotates, the rotational force is transmitted to the winding unit 200.

The main body 400 is a member for holding the storage roller portion 100 and the winding portion 200. In the main body 400, as shown in FIG. 1, a grip portion 410 is fixedly provided. The grip portion 410 is a member for holding the hand when the user uses the stick roller type cleaning tool 1 , and the user holds the stick roller cleaning tool 1 into the object to be cleaned while holding the grip portion 410 . The stocker roller unit 100 moves forward and backward and rotates to clean the garbage such as dust.

In the present embodiment, the rotation operation transmitting unit 300 is composed of a plurality of gears. That is, as shown in FIGS. 1 and 2, the gear 120 fixed to the rotation shaft 110 of the stock roller unit 100 and the rotation shaft 210 of the winding unit 200 are fixed coaxially. The gear 220 is composed of one or a plurality of transmission gears 310 for transmitting the rotation of the gear 120 of the stock roller unit 100 to the gear 220 of the gear 220 of the winding unit 200. With this configuration, the rotational force of the storage roller unit 100 can be transmitted to the winding unit 200 all the time.

The stocker roller unit 100 has a configuration in which a rotation control mechanism 500 is provided between the gear 120 and the rotating shaft 110 as shown in Fig. 1 . The rotation control mechanism 500 is a mechanism that transmits the rotational torque of the rotary shaft 110 to the gear 120 only when the rotary shaft 110 is rotated in a specific direction. In the present embodiment, it is only in the storage roller portion 100. When the rotation is performed in the forward direction, the rotational force is transmitted to the gear 120, and the rotational force is transmitted to the winding unit 200 via the rotational motion transmitting unit 300.

In other words, when the rotation of the stock roller unit 100 is transmitted to the winding unit 200, when the storage roller unit 100 rotates in the front direction (that is, when the adhesive tape 10a is pulled out), This rotational force is transmitted to the winding unit 200, and when the storage roller unit 100 rotates in the backward direction (that is, when the storage roller unit 100 winds up the adhesive tape 10b), it is controlled so as not to transmit the rotational force to the volume. The operation of the unit 200 is performed.

When the storage roller unit 100 rotates in the backward direction (when the storage roller unit 100 winds up the adhesive tape 10b. That is, when the adhesive tape 10b is pulled out from the winding unit 200), the rotational torque from the gear 120 is It is transmitted to the rotating shaft 110.

It is assumed that, for example, the number of rotations (rotational speed) of the storage roller unit 100 in the backward direction is more (faster) than the number of rotations (rotation speed) of the winding unit 200 (that is, the adhesive tape 10b has been When the winding torque is transmitted from the gear 120 to the rotating shaft 110, the rotational speed difference between the rotating shaft 110 and the gear 120 that has rotated in the backward direction is generated (rotation speed). However, since the number of rotations (rotational speed) of the gear 120 is small (slow), the transmission of the rotational moment of the rotating shaft 110 acts as a direction to be avoided and suppressed. In other words, the rotation control mechanism 500 functions as a cushioning material that absorbs the difference in rotation number (rotational speed difference) between the rotating shaft 110 and the gear 120.

Similarly, the number of rotations (rotational speed) of the storage roller 100 to the rear is smaller (slower) than the number of rotations (rotational speed) of the winding unit 200, and the same effect as described above is generated, and absorption rotation is performed. The difference in the number of revolutions between the shaft 110 and the gear 120 (the difference in rotational speed).

Next, the specific operation of the stick roller type cleaning tool 1 will be described. As shown in Fig. 2, when the stocker roller unit 100 is rotated in the forward direction, the adhesive tape 10a which is wound (accumulated) into a cylindrical shape is pulled out. At this time, the end portion of the adhesive tape 10a is connected to the winding portion 200. The rotation of the stock roller unit 100 in the front direction is transmitted to the winding unit 200 via the rotation operation transmitting unit 300 by the operation of the rotation control mechanism 500. Since the winding unit 200 rotates in accordance with the operation of the storage roller unit 100, the adhesive tape 10b to which the garbage or the like has adhered is rotated in the winding direction, and the adhesive tape 10b is taken up and collected.

On the other hand, when the storage roller unit 100 rotates in the backward direction, the rotational force is not transmitted to the rotational operation transmitting unit 300 or the winding unit 200 by the rotation control mechanism 500. However, since the adhesive tape 10b which is taken up and collected in the winding unit 200 is pulled by the rotation of the storage roller unit 100, the adhesive tape 10b is pulled out from the winding unit 200 by the storage roller. Department 100 takes the recycling.

At this time, in the rotation control mechanism 500, the rotational force is transmitted via the rotational operation transmitting unit 300. However, as described above, the rotational control mechanism 500 serves as the rotational number difference between the absorption rotary shaft 110 and the gear 120. The function of the role of the cushioning material (difference in rotational speed).

With this configuration, even if the adhesive tape 10a wound by the storage roller unit 100 and the adhesive tape 10b to which the wound portion 200 is wound and adhered with dust or the like is caused to have a difference in outer circumference, the rotation control mechanism The 500 can also absorb the number of rotations (rotational speed), so that the pull-out or take-up of the stable adhesive tapes 10a, 10b can be repeated. Further, when the storage roller unit 100 is rotated in the backward direction by the rotation control mechanism 500, it is possible to suppress the excessive rotation of the winding unit 200, and it is possible to suppress the slack of the adhesive tape 10b wound by the storage roller unit 100.

The rotation operation transmitting unit 300 may be configured to use a pulley and a belt instead of a plurality of gears. That is, as shown in FIG. 3, the rotation operation transmitting unit 300 is provided coaxially with the pulley 130 disposed coaxially with the rotating shaft 110 of the stocking roller unit 100 and the rotating shaft 210 of the winding unit 200. The pulley 230 and the belt body 320 for conveying the rotation of the pulley 130 of the stock roller unit 100 to the pulley 230 of the winding unit 200 are constituted. With this configuration, the rotational force of the storage roller unit 100 can be transmitted to the winding unit 200 all the time.

Further, the storage roller unit 100 is configured such that a rotation control mechanism 500 is provided between the pulley 130 and the rotating shaft 110. As described above, when the rotation of the storage roller unit 100 is transmitted to the winding unit 200, the rotation control unit 500 rotates the storage roller unit 100 in the forward direction (that is, when the adhesive tape 10a is pulled out). The rotation force is transmitted to the winding unit 200, and when the storage roller unit 100 rotates in the backward direction (that is, when the storage roller unit 100 winds up the adhesive tape 10b), it is used to avoid and suppress the rotation force transmission. To the winding unit 200. With this configuration, the rotational force of the stock roller unit 100 can be transmitted to the winding unit 200 with a simple structure.

The rotation control mechanism 500, in this embodiment, is constructed using a one-way clutch 510. The one-way clutch 510 is a mechanism for transmitting a torque in a single direction between the inner and outer wheels on the coaxial side, and in this embodiment, by setting the lock state when the storage roller unit 100 is rotated in the forward direction, The rotation of the storage roller unit 100 in the forward direction is transmitted to the rotation operation transmitting unit 300 via the gear 120 (pulley 130), and then the rotational force is transmitted to the winding unit 200. Further, when the storage roller unit 100 is rotated in the backward direction, the lock release state is eliminated, and the rotation of the storage roller unit 100 in the backward direction is prevented from being transmitted to the gear 120 (the pulley 130), thereby preventing the rotation. The force is transmitted to the configuration of the rotational motion transmitting unit 300.

With this configuration, it is possible to realize the rotation control in the single direction by the rotation control mechanism 500, and it is possible to compensate for the difference in the rotational speed between the storage roller unit 100 and the winding unit 200.

As shown in FIG. 1, the rotation operation transmitting unit 300 can be configured such that the toothed device is equipped with an even number of transmission gears 310. With this configuration, the direction in which the storage roller unit 100 and the winding unit 200 rotate is opposite. Thereby, if the rotation direction of the storage roller unit 100 and the winding unit 200 is the same, the drawing or winding process of the stable adhesive tapes 10a and 10b can be realized.

Further, as shown in FIG. 3, the rotation operation transmitting unit 300 is such that the belt body 320 is crossed, and the pulley 130 of the storage roller unit 100 and the pulley 230 of the winding unit 200 are wound in a linked manner. With this configuration, the direction in which the storage roller unit 100 and the winding unit 200 rotate in opposite directions is compared with each other, and the rotation direction of the storage roller unit 100 and the winding unit 200 is the same, thereby achieving stability. The pull-out or take-up process of the adhesive tapes 10a, 10b.

The rotation operation transmitting unit 300 can be configured to set the gear ratio of the gear 120 of the storage roller unit 100 and the gear 220 of the winding unit 200 to be low. With this configuration, the difference in the number of rotations (rotational speed difference) between the gear 120 of the storage roller unit 100 and the gear 220 of the winding unit 200 can be intentionally generated, and as a result, the adhesion of the adhesive tape can be stabilized. Pull out or take-up operation. Further, it is preferable that the gear ratio is set to 1:1.14 or lower, whereby a stable pull-out or take-up operation can be realized, but it is not limited by the gear ratio.

Further, the rotation operation transmitting unit 300 can be configured such that the pulley 130 of the storage roller unit 100 is larger than the pulley 230 of the winding unit 200. With this configuration, the difference in the number of rotations (rotational speed difference) between the pulley 130 of the storage roller unit 100 and the pulley 230 of the winding unit 200 can be intentionally generated, and as a result, the adhesion of the adhesive tape can be stabilized.
