Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a brush roll contact amount detecting device for a steel plate cleaning device for cleaning a steel plate used for a vehicle body or the like.

[0002]

[Prior art]

 Conventionally, the apparatus shown in FIG. 3 has been used as a steel plate cleaning apparatus. That is, the insertion opening 32 is provided at one end of the frame 31, and the outlet 33 is provided at the other end. The frame 31 has a pair of pinch rolls 34a and 34b, brush rolls 35a and 35b, first oil cut rolls 36a and 36b, and second oil cut rolls 37a and 37b from the insertion port 32 side to the ejection port 33 side. The rolls 34a to 37b are arranged so as to be rotationally driven by a motor.

In such a structure, when the steel plate S is cleaned, an adjustment screw (not shown) is operated with the brush rolls 35a and 35b stopped to set the lap allowance of the brush tip to a predetermined value. In this way, the axial distance between both rolls 35a and 35b is adjusted. Thereafter, the power source is turned on, and the rolls 34a to 37b are rotationally driven by the motor, and the steel plate S is put into the insertion opening 32. Then, the steel plate S is transferred in the direction of the outlet 33 by the pinch rolls 34a and 34b, and the surface thereof is wiped by the brush rolls 35a and 35b. Next, after the oil adhering to the surface is removed by the first and second oil cut rolls 36a, 36b, 37a, 37b, the oil is delivered from the outlet 33 to the outside.

When the steel plate S is cleaned in this way, the tip ends of the brush rolls 35a and 35b are worn by friction with the steel plate S, and as a result, the surface of the steel plate S is properly wiped. The situation that cannot be obtained occurs. Therefore, when an appropriate amount of time has passed, turn off the power supply and check the wrap margin of the brush tips of both rolls 35a and 35b. If the lap margin is small, operate the adjusting screw again, The axial distance between the rolls 35a and 35b is reduced so that an appropriate amount of contact can be obtained.

[0005]

[Problems to be solved by the device]

 However, in such a conventional steel plate cleaning apparatus, when the axial distance between the brush rolls 35a and 35b is adjusted, the lap margin of the brush tip portions of both rolls 35a and 35b is visually confirmed. At this time, since the pinch rolls 34a, 34b and the first oil cut rolls 36a, 36b are mounted on both sides of the brush rolls 35a, 35b, the light is shielded and it is dark. It is not possible to see the lap allowance with certainty, and the rough adjustment is used to adjust the axial distance. As a result, the amount of contact of the brush rolls 35a and 35b with the steel plate S becomes too small, and the steel plate S cannot be sufficiently cleaned, or conversely, the amount of contact becomes too large, and the brush rolls 35a and 35b. There were inconveniences such as accelerated wear of the.

The present invention has been made in view of such conventional problems, and provides a brush roll contact amount detection device for a steel plate cleaning device capable of clearly confirming the contact amount of the brush roll with respect to the steel plate. That is the purpose.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, a pair of brush rollers is rotatably driven in a steel plate cleaning apparatus for cleaning a steel plate by passing a steel plate between a pair of rotationally driven brush rolls. An ammeter is inserted between the motor and the power supply.

[0008]

[Action]

 In the above configuration, when the axial distance between the pair of brush rolls is too large, the contact amount of the brush rolls with the steel plate becomes too small, so that the load on the motor that rotationally drives the brush rolls decreases. Therefore, the current flowing through the motor is also reduced, and the reduced current value is displayed on the ammeter. On the other hand, when the axial distance between the pair of brush rolls is too small, the contact amount of the brush rolls with the steel plate becomes too large, which increases the load on the motor that rotationally drives the brush rolls. Therefore, the current flowing through the motor also increases, and this increased current value is displayed on the ammeter.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. That is, as shown in FIG. 1, the insertion opening 2 is provided at one end of the frame 1 and the extraction opening 3 is provided at the other end. A pair of pinch rolls 4a and 4b, brush rolls 5a and 5b, first oil cut rolls 6a and 6b, and second oil cut rolls 7a and 7b are arranged on the frame 1 from the insertion port 2 side to the ejection port 3 side. Has been done.

Motors 8a and 8b are disposed above and below the brush rolls 5a and 5b, and between the rotary shafts of the motors 8a and 8b and the corresponding rotary shafts of the brush rolls 5a and 5b. Belts 9a and 9b are mounted respectively. The rolls 4a, 4b, 6a, 6b, 7a and 7b other than the brush rolls 5a and 5b are driven by a motor (not shown).

As shown in FIG. 2, the motors 8a and 8b are connected to DC power supplies 11a and 11b having the same output, and a DC current is supplied between the DC power supplies 11a and 11b and the motors 8a and 8b. Ammeters 12a and 12b for detecting the voltage and switches 13a and 13b interlocking with each other are inserted. The switch of the motor for driving the other rolls 34a to 37b is also interlocked with the switches 13a and 13b, and the distance between the axes of the brush rolls 5a and 5b is adjusted by screwing the adjusting screws 10a and 10b. It is configured to decrease and increase by screwing back.

In the present embodiment having the above-described configuration, the steel plate S is washed once experimentally with the brush tips of the brush rolls 5a and 5b being in an appropriate lapping margin. The current flowing through 8b, that is, the indicated value of the ammeters 12a and 12b is read, written as a proper current value on a plate or the like, and attached to the side of the ammeters 12a and 12b, for example. When the switches 13a and 13b are turned on when actually cleaning the steel plate S, the motors 8a and 8b rotate to drive the brush rolls 5a and 5b, and the other rolls 4a to 7b also move to other motors. It is driven to rotate by.

In this state, when the steel plate S is put into the insertion port 2, the steel plate S is transferred by the pinch rolls 4a and 4b toward the outlet port 3 and the surface is wiped by the brush rolls 5a and 5b. Next, after the oil adhering to the surface is removed by the first and second oil cut rolls 36a, 36b, 37a, 37b, it is sent out through the outlet 33. Then, when the cleaning of the steel plate S is started, the operator reads the current value which is the instruction value of the ammeters 12a and 12b and compares it with the appropriate current value. As a result, if the current value is close to the appropriate current value, the axial distance between the brush rolls 5a and 5b and the amount of contact with the steel plate S can be considered appropriate.

When the axial distance between the brush rolls 5a and 5b is too large, the contact amount of the brush rolls 5a and 5b with the steel plate S becomes too small, so that the load on the motors 8a and 8b decreases. To do. Therefore, the current flowing through the motors 8a and 8b is also reduced, and the current value is displayed on the ammeters 12a and 12b although it is below the proper current value. Therefore, in this case, the adjusting screws 10a and 10b are screwed to reduce the distance between the shafts, whereby the contact amount of the brush rolls 5a and 5b can be made appropriate.

On the contrary, when the axial distance between the brush rolls 5a and 5b is too small, the contact amount of the brush rolls 5a and 5b with respect to the steel plate S becomes too large, so that the load on the motors 8a and 8b is increased. Increase. Therefore, the current flowing through the motors 8a and 8b also increases, and the increased current value is displayed on the ammeters 8a and 8b. Therefore, in this case, the contact amounts of the brush rolls 5a and 5b can be made proper by screwing the adjusting screws 10a and 10b back and increasing the axial distance.

When the appropriate contact amount is set on the brush rolls 5 a and 5 b in this way and the steel plate S of the steel plate S is washed, the brush rolls 5 a and 5 b are affected by friction with the steel plate S. The tip is worn. Then, since the load on the motors 8a and 8b is reduced, the current value is displayed on the ammeters 12a and 12b although the current value is less than the appropriate current value. Therefore, in this case, the contact amounts of the brush rolls 5a and 5b can be made appropriate by screwing the adjusting screws 10a and 10b to reduce the axial distance.

In the embodiment, the brush rolls 5a, 5b are individually driven to rotate by the different motors 8a, 8b via the belt 9. However, the brush rolls 5a, 5b are connected to the timing belt or the chain. Alternatively, a single motor may be used to rotate the motor, and an ammeter may be inserted between the motor and the power supply. Further, in the embodiment, the DC power source and the DC ammeter are used. However, when the AC power source and the AC ammeter are used, the contact amount of the brush rolls 5a and 5b with the steel plate S is similarly determined by the current value. Of course, it can be detected.

[0018]

[Effect of device]

 As described above, according to the present invention, the ammeter is inserted between the motor and the power source for rotating the brush roller of the steel plate cleaning device. Therefore, the amount of contact between the brush roll and the steel plate can be easily and accurately known from the current value indicated by the ammeter, and the contact amount of the brush roll against the steel plate can be precisely adjusted to determine the appropriateness of the steel plate. It is possible to achieve proper cleaning and suppress the abrasion of the brush roll.
