[Industrial applications]

 In this invention, a raising member such as sandpaper or a sand cloth is wound around a pair of raising rollers provided at a required interval, and the raising members are circulated between the raising rollers as the raising rollers rotate. The present invention relates to a raising device that continuously raises the surface of a fabric that is run by this raising member. More specifically, the raising member wound around a raising roller is offset from its normal position in the axial direction of the raising roller. The present invention also relates to a raising device in which a raised raising member is immediately returned to a normal position even in the case of being raised, and the surface of the fabric is raised in a stable state by the raising member in the normal position.

[Prior art]

 Conventionally, when raising the surface of a fabric continuously, as shown in FIG. 1, a raising member 2 such as sandpaper or a sand cloth is wound around a pair of raising rollers 3 provided at required intervals, The nap raising roller 3 (the nap raising roller 3 located below in the example shown in the figure) is rotated by a motor 4 via a belt 4a and a pulley 4b, and the nap raising member 3 is rotated as the nap raising roller 3 rotates. A raising device has been used in which 2 is circulated between raising rollers 3, and the surface of the fabric 1 that is running is continuously raised by the raising member 2 that circulates in this way.

Here, when the surface of the cloth 1 is continuously raised as described above, the raising member 2 wound around the raising roller 3 is used for raising without permission during raising. The roller 3 sometimes shifts in the axial direction and shifts to one side, which causes a situation in which the running surface of the cloth 1 cannot be raised in a stable state.

Therefore, even in the conventional raising device, as shown in the figure, in order to detect the deviation of the raising member 2 in the vicinity of one end in the width direction of the circulating raising member 2 as described above. A suitable sensor 5 is provided on the nap raising roller 3 and the nap raising roller 3 located above the nap raising roller 3 that is driven to rotate is pushed or pulled to push or pull the bearing 3b of the rotating shaft 3a of the nap raising roller 3 that is driven to rotate. A cylinder 6 for inclining was used.

When the nap raising member 2 shifts in the axial direction of the nap raising roller 3 and is offset, the offset in the nap raising member 2 is detected by the sensor 5, and based on this, the control device 7 is controlled. The expanding / contracting rod 6a of the cylinder 6 is expanded / contracted to incline the nap raising roller 3 that is driven to rotate, whereby the nap raising member 2 is moved in the axial direction of the nap raising roller 3, and the nap raising member 2 is offset. I was trying to correct.

Here, in the conventional raising device, since one sensor 5 detects the deviation of the raising member 2 as described above, as shown in (A) and (B) of FIG. If the nap member 2 deviates from the normal position indicated by the chain double-dashed line in the figures to either the left or the right in the axial direction of the nap roller 3, the sensor 5 will be in the ON or OFF state. In either case, the control device 7 causes the expansion / contraction rod 6a of the cylinder 6 to expand or contract, thereby changing the inclination angle of the nap raising roller 3 that is driven to rotate. It became so.

However, even when the sensor 5 is turned on or off in this way, if the inclination angle of the raising roller 3 that is driven to rotate by the cylinder 6 is changed, the raising roller will be changed. The problem that the inclination angle in 3 is changed frequently, hunting is increased, the device is severely damaged, and the running fabric 1 cannot be raised in a stable state by the raising member 2. There was a problem.

Further, in the conventional raising device, only one sensor 5 detects whether or not the raising member 2 is offset as described above. Regarding the size of the offset of the raising member 2, When it is not detected and the deviation in the raising member 2 is detected, the expansion rod 6a of the cylinder 6 is always extended or contracted by a constant length regardless of the size of the deviation in the raising member 2. The nap raising roller 3 that is driven to rotate is inclined at a predetermined angle.

Therefore, even when the nap raising member 2 is abruptly largely displaced and offset, only the same control as in the case where the nap raising member 2 is slightly offset is performed. The time required to return to the normal position becomes long, and the time when the surface of the cloth 1 is raised by the raising member 2 in an unbalanced state becomes long, and the surface of the cloth 1 cannot be raised in an appropriate state. There was also a problem.

[Problems to be solved by the device]

 In this invention, a raising member such as sandpaper or a sand cloth is wound around a pair of raising rollers provided at a required interval, and the raising members are circulated between the raising rollers as the raising rollers rotate. It is an object of the present invention to solve the above-mentioned problems in a raising device which continuously raises the surface of a fabric running by the raising member.

That is, according to the present invention, in the above-mentioned raising device, when the raising member wound around the raising roller is arbitrarily shifted in the axial direction of the raising roller and is biased, the raising roller is suitable. By tilting to the right, the deviation in the raising member is quickly corrected, and the raising member is immediately returned to the normal position so that the surface of the fabric is raised in a stable state by the raising member in the normal position. It is an issue.

[0012]

[Means for Solving the Problems]

 In this invention, in order to solve the above-mentioned problems, a raising member 2 such as sandpaper or a sand cloth is wound around a pair of raising rollers 3 provided with a required space, and the raising roller 3 is rotated. In accordance with the above, the raising member 2 is circulated between the raising rollers 3, and the raising device 2 continuously raises the surface of the cloth 1 running by the raising member 2 in the raising device. Is raised from its normal position in the axial direction of the nap raising roller 3, and a detection device 11 for detecting the size of the nap of the nap raising member 2 and the nap raising roller 2 by tilting the nap raising roller 3 The tilting device 12 for moving the roller 3 in the axial direction, and the tilting device based on the size of the deviation in the raising member 2 detected by the detecting device 11. 12 by it was acceptable to provide a control device 13 for controlling the angle of tilting the brushed roller 3.

Here, the detecting device 11 provided in the raising device is provided with a deviation in the raising member 2 when the raising member 2 is offset from its normal position in the axial direction of the raising roller 3 as described above. Any device can be used as long as it can detect the size of the raised portion 2. However, the detection device 11 can easily and accurately detect the size of the offset of the raised member 2 without being affected by the surrounding environment. It is preferable to use, for example, a plurality of air sensors for detecting by spraying air are arranged side by side in a manifold type, and a plurality of air sensors arranged side by side are The fluffing member 2 is arranged so as to be located on both the inner and outer sides of the widthwise end, and the fluffing member 2 is offset by the position of the air sensor that is blocked by the fluffing member 2. It can be made to detect the size of the ball.

[Action]

 In the raising device according to the present invention, the raising member 2 wound around the pair of raising rollers 3 provided at a required interval is circulated between the raising rollers 3 as the raising roller 3 rotates. In the case where the nap raising member 2 arbitrarily shifts in the axial direction of the nap raising roller 3 while being napped continuously on the surface of the cloth 1 traveling by the nap raising member 2, The one-sided size is detected by the detection device 11.

Then, based on the one-sided size of the nap raising member 2 detected by the detection device 11 as described above, the control device 13 adjusts the angle at which the nap raising roller 3 is inclined by the inclination device 12. The unevenness of the raised member 2 is corrected.

When the deviation of the raising member 2 is corrected in this way, when the deviation of the raising member 2 is large, the tilting device 12 causes the raising roller 3 to be greatly inclined, The fluffed member 2 that is largely offset is quickly returned to the normal position.

【Example】

 Hereinafter, a raising device according to an embodiment of the present invention will be specifically described with reference to the accompanying drawings.

Also in the raising device in this embodiment, as shown in FIG. 3, the raising members 2 such as sandpaper and sand cloth are made endless, and the raising members 2 are provided with a pair of raising members provided at a required interval. The roller 3 is wrapped around.

Then, one of the raising rollers 3 (in the example shown in the figure, the raising roller 3 located below) on which the raising member 2 is wound is rotated by the motor 4 via the belt 4a and the pulley 4b. As the nap raising roller 3 rotates, the nap raising member 2 is circulated between the nap raising rollers 3 and the surface of the running fabric 1 is continuously raised by the nap raising member 2 circulating in this way. I chose

Here, in the raising device of this embodiment, the raising member 2 arbitrarily raises the raising roller while the surface of the cloth 1 traveling by the raising member 2 is being raised continuously as described above. In the case where the detecting device 11 detects the size of the deviation in the nap member 2 when it is deviated in the axial direction of 3, the detection device 11 uses four air sensors 11a and 11b that perform detection by blowing air. , 11c, 11d are arranged side by side with a required space, and the four air sensors 11a to 11d arranged side by side are arranged so as to be located on both inside and outside of one end in the width direction of the raising member 2. did.

Then, based on the positions of the air sensors 11a to 11d blocked by the raising member 2, the direction and size of the deviation of the raising member 2 are detected.

When the raising member 2 is arbitrarily displaced in the axial direction of the raising roller 3 and is offset, the raising roller 3 is tilted to move the raising member 2 in the raising roller 3 axial direction. As the tilting device 12, in this embodiment, the telescopic rod 12a of the cylinder 12 is connected to the bearing 3b of the rotary shaft 3a of the raising roller 3 which is located above the raising roller 3 which is rotationally driven and is driven to rotate. .

The telescopic rod 12a of the cylinder 12 is expanded and contracted to incline the nap raising roller 3 that is driven to rotate, thereby moving the nap raising member 2 in the axial direction of the nap raising roller 3. .

Further, based on the size of the deviation in the raised member 2 detected by the air sensors 11a to 11d, the control device 13 causes the expansion / contraction rod 12a in the cylinder 12 to expand / contract, thereby causing the driven member to move. In controlling the angle at which the rotating raising roller 3 is tilted, in this embodiment, a signal indicating the position of the air sensors 11a to 11d blocked by the raising member 2 is sent from the air sensors 11a to 11d side. The controller 13 controls the controller 13 to change the length of expansion and contraction of the telescopic rod 12a in the cylinder 12 based on this signal, and as shown in FIG. 4, the raising roller to which the telescopic rod 12a is connected. Move the bearings 3b of No. 3 to the corresponding positions of points A, B, C, D and E, and The angle of inclination of the hair roller 3 was adjusted.

Here, in this embodiment, the bearing 3b of the nap raising roller 3 to which the telescopic rod 12a is connected is moved to the positions A, B, C, D and E, and the nap raising roller 3 is moved. As shown in FIG. 5, when adjusting the inclination angle of No. 3, the normal position is the case where one end of the nap member 2 in the width direction is located between the air sensors 11b and 11c. The bearing 3b is set to the position C, and when the raising device is operated in this state, the expandable rod 12a of the cylinder 12 is not expanded or contracted so that the bearing 3b is maintained at the position C. I chose

Then, in the state where the raising device is normally operated in this manner, the one end in the width direction of the raising member 2 is displaced to the outside in the axial direction of the raising roller 3, and as shown in FIG. When the air sensor 11c is blocked by the napping member 2, the controller 13 extends the telescopic rod 12a of the cylinder 12 to move the bearing 3b to the position D, and the napping roller 3 described above. Was slightly tilted to return the raising member 2 to the normal position.

Further, one end in the width direction of the napping member 2 abruptly largely shifts to the outside in the axial direction of the napping roller 3, and as shown in FIG. 7, the air sensor 11 d is also blocked by the napping member 2. In this case, the controller 13 causes the expansion rod 12a of the cylinder 12 to be greatly extended, the bearing 3b to be moved to the position of point E, the raising roller 3 to be greatly inclined, and the raising member 2 to be quickly moved. I tried to return it to the normal position.

On the other hand, in the state where the raising device is operating normally, contrary to the above case, one end in the width direction of the raising member 2 is displaced inward in the axial direction of the raising roller 3, As shown in 8, when the air sensor 11b is no longer blocked by the raising member 2, the controller 13 causes the telescopic rod 12a of the cylinder 12 to contract to move the bearing 3b to the position of point B. The raising roller 3 was slightly tilted in the opposite direction to the above case so that the raising member 2 was returned to the normal position.

Further, one end of the nap raising member 2 in the width direction is abruptly displaced inward in the axial direction of the nap raising roller 3, and the air sensor 11a is not blocked by the nap raising member 2 as shown in FIG. In this case, the control device 13 causes the expansion / contraction rod 12a of the cylinder 12 to largely contract, the bearing 3b to move to the position of point A, and the nap raising roller 3 to be greatly inclined so that the nap raising member 2 is moved. I tried to quickly return to the normal position.

After returning the raised member 2 which is in the state of being displaced to the normal position as described above, the bearing 3b of the raising roller 3 to which the expansion rod 12a is connected is maintained at the position C. By doing so, the fabric 1 running while keeping the raising member 2 in the normal position is raised.

[Effect of device]

 As described above in detail, in the raising device according to the present invention, the raising member wound around the pair of raising rollers provided at a required interval is provided between the raising rollers as the raising roller rotates. When the fabric is circulated and is continuously raised on the surface of the running fabric by the raising member, if the raising member is arbitrarily displaced in the axial direction of the raising roller and is offset, the size of the offset of the raising member is increased. Of the fluffing member, the tilting device is controlled by the control device to adjust the angle at which the napping roller is tilted, based on the deviation of the napping member detected in this way. I tried to correct the bias.

As a result, when the surface of the running fabric is continuously raised by using the raising device according to the present invention, even if the raising member shifts in the axial direction of the raising roller without permission, it is offset. , The raising member is returned to the normal position, the surface of the fabric is stably raised by the raising member in the normal position, and even if the raising member has a large deviation, It quickly returned to the normal position, and the surface of the fabric became stable and raised.
