Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning apparatus for a surface of a product,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for a surface of a product and a cleaning system for a surface of a product using the cleaning device, And a surface cleaning system using the same.

Generally, materials and auxiliary materials used in production process are strictly controlled, but fine foreign substances on the surface of the product can not be completely removed. This is due to the electrostatic force and the stickiness of the dust itself during the production of the product, which is the main cause of the quality deterioration.

Since these foreign materials are a main cause of defects in the manufacturing process of the product, various technologies for removing these foreign materials have been developed.

For example, as shown in Fig. 1, a foreign matter removing device includes a conveyor 1 installed on the left and right sides for conveying the product F, and a conveyor 1 installed between the conveyor 1 on both sides A cleaning roller 2, an adhesion roller 3 which rotates in contact with the cleaning roller 2, and a roller rotation unit (not shown).

The other side of the cleaning roller 2 is connected to a motor (not shown), and the other side is rotated by its own weight while being in contact with the product F.

In this configuration, in the process of being transported by the conveyor 1, the plate-like product F is contacted with the upper and lower surfaces of the cleaning roller 2 to separate the foreign substances O, And adheres to the pressure-sensitive adhesive roller 3 in contact with the pressure-sensitive adhesive layer 2 to be removed. Here, when the adhesive force is exhausted in a state in which the adhesive rollers 3 are rolled up by overlapping multiple sheets of adhesive paper on the plate (i.e., in the form of a rolled adhesive tape), the adhesive paper at the outermost edge is peeled off and a new adhesive surface is exposed, (O) is completely removed from the apparatus.

At this time, when the cleaning roller 2 rotates at a different rotational speed when only one side of the cleaning roller 2 is connected to the motor and the other side rotates due to its own weight, There is a problem that a curling phenomenon occurs in which the cleaning roller 2 is curled up.

Particularly, since the distance between the cleaning rollers 2 is fixed, when the thickness of the product F is too small, the cleaning roller 2 does not contact the cleaning roller 2 properly and the foreign substance O is not properly removed. In this case, the defective rate of the product F is increased.

Then, the controller C calculates a pressure difference between the pressure detected by the discharge sensor 540 and the preset pressure value stored in the storage 542, and the pressure value difference is stored in the storage 542 Of the set pressure range stored in the set pressure range.

When the pressure value difference is out of the set pressure range, the controller C judges that the filter cleaning time point and generates a filter cleaning signal. Then, the filter cleaning signal of the controller C is transmitted to the speaker 544 to inform the user by sound.

As shown in FIG. 6, a sub-suction chamber 550 is installed in a direction opposite to the suction chamber 510 with respect to the spray cleaning module 400. The sub suction chamber 550 is connected to the ring blower 520 and serves to suck foreign substances together with the suction chamber 510.

3 or 7, an operation unit 600 is installed on one side of the housing 100. [ The operation unit 600 can arbitrarily control operations of the transfer module 200, the product surface cleaning apparatus 300, the spray cleaning module 400, and the suction module 500.

A controller (C) is provided in the housing (100). The controller C stores set values inputted from the operation unit 600 and controls the feed module 200 and the product surface cleaning apparatus 300, the spray cleaning module 400, and the suction module 500).

7, a transfer sensor S1 is installed at one side of the transfer module 200 facing the entrance 110a of the cleaning space 110 of the housing 100. As shown in FIG. The conveyance sensing senl S1 senses the product and transmits a signal to the controller C so that the controller C controls the operation of the moving module.

An input sensor S2 is installed at an inlet 110a of the cleaning space 110 of the housing 100. [ The input sensing sensor S2 senses the product so that the controller C controls the operation of the product surface cleaning device 300, the spray cleaning module 400, and the suction module 500. [ (C).

A discharge sensor S3 is installed at an outlet 100b of the cleaning space 110 of the housing 100. [ The discharge sensor S3 senses the product passing through the cleaning space 110 and controls the operations of the product surface cleaning device 300, the spray cleaning module 400 and the suction module 500 And transmits the signal to the controller (C).

The operation of the feed detection sensor S1, the feed detection sensor S2, and the discharge detection sensor S3 will be described in detail below.

Next, operations of the cleaning apparatus for product surface according to one embodiment of the present invention and the cleaning system for product surface using the same will be described.

First, the operator operates the cleaning system 10 for the product surface by operating the operation unit 600. In this state, when the product is placed on the conveying module 200 facing the inlet 110a of the cleaning space 110, the conveyance detecting sensor S1 senses it and sends a signal to the controller C . The controller C receives a signal from the transport sensor S1 and drives the transport module 200 and the product surface cleaning apparatus 300 and the ionizer.

The product enters the inlet 110a of the cleaning space 110 along the feed module 200 and at the same time the insertion detection sensor S2 senses the product and the controller C Lt; / RTI > The controller C receives a signal from the injection detection sensor S2 and drives the injection cleaning module 400 and the suction module 500.

As described above, when the product enters the cleaning space 110, the clean rollers 330 and 340 of the product surface cleaning apparatus 300 contact the surface of the product to remove and collect foreign substances.

Since the upper and lower bobper gears 350 and 360 coupled to the upper and lower roller shafts 310 and 320 are rotated in directions opposite to each other by the power transmission gear 380, The curling phenomenon of being rolled up on the clean rollers 330 and 340 during the separation process is prevented.

At the same time, air is blown toward the clean rollers 330 and 340 through the injection nozzle 450 of the spray cleaning module 400 to separate the foreign substances collected in the clean rollers 330 and 340, The foreign substances separated from the clean rollers 330 and 340 are sucked through the suction chamber 510 of the suction module 500 by driving the blower 520.

At this time, the upper and lower air branch lines 420 and 430 connected to the injection nozzle 450 of the spray cleaning module 400 are opened and closed by the upper and lower solenoid valves B1 and B2, respectively. If the air is blocked by the upper and lower solenoid valves B1 and B2 while the air is continuously supplied, the pressure of the air instantaneously rises and the pressure of the air can be increased without requiring a separate compression tank The production time of the product can be reduced.

The product having the foreign object removed is discharged to the outlet 110b of the cleaning space 110. The discharge sensor S3 senses the product and sends a signal to the controller C, C receives a signal from the discharge sensor S3 to perform operations of the transfer module 200, the product surface cleaning device 300, the spray cleaning module 400, and the suction module 500 .

At this time, the controller C checks the detection time of the input detection sensor S2 and the discharge detection sensor S3, compares the detection time with the reference value stored in the controller C, And controls the operations of the product surface cleaning apparatus 300, the spray cleaning module 400, and the suction module 500. The suction cleaning module 400 may be provided with a cleaning function.

For example, if the movement time is six seconds when one product is normally detected by the discharge detection sensor S3 through the input detection sensor S2, the reference value stored in the controller C is set to 6.2 seconds . At this time, if the moving time exceeds 6.2 seconds when the product is detected by the discharge detection sensor (S3) through the input detection sensor (S2), the controller (C) judges that the product exceeds the stored reference value, The driving of the surface cleaning apparatus 300, the spray cleaning module 400, and the suction module 500 is stopped.

When the controller C stops the operation, the operator can visually confirm whether the product is curled up on the clean rollers 330 and 340. [

Meanwhile, when a foreign object is removed from a product having a thickness different from that of the product that has been subjected to the previous removal process, the user operates the operation unit 600 to input a set value corresponding to the thickness of the product. For example, when the user inputs a set value of the thickness of the product to 90 micrometers, the set value is input to the controller C. [

In this case, the servo motor SM connected to the upper roller shaft 310 is operated under the control of the controller C. At this time, when the set value inputted by the user is thinner than the thickness of the product which performed the previous foreign matter removal operation, the servo motor SM rotates the upper roller shaft 310 (310) in the direction in which the clean rollers ).

8A, when the servo motor SM moves the upper roller shaft 310 downward, the upper roller shaft 310 moves along the guide slit 120 of the housing 100 The upper spur gear 350 coupled with the upper roller shaft 310 is moved downward together with the upper roller shaft 310 and the upper swing gear 350 is moved downward, The upper bumper gear 350 can be smoothly lowered as the gear 383 moves in the horizontal direction, that is, in the direction of arrow B by the swing arm 390.

As a result, the distance between the clean rollers 330 and 340 becomes close to the thickness of the product, so that the product contacts the clean rollers 330 and 340 and foreign matter can be properly removed.

On the other hand, when the set value inputted by the user is thicker than the thickness of the product which has performed the previous foreign matter removing operation, the servo motor SM detects that the clean rollers 330 and 340 of the product surface- The upper roller shaft 310 is moved in the direction of the arrow.

8B, when the servo motor SM moves the upper roller shaft 310 upward, the upper roller shaft 310 moves along the guide slit 120 of the housing 100 The upper spur gear 350 coupled with the upper roller shaft 310 is moved upward together with the upper roller shaft 310 and the upper swing gear 350 is moved upward together with the upper roller shaft 310, As the gear 383 moves in the horizontal direction, that is, in the direction of arrow D by the swing arm 390, the upper bumper gear 350 can smoothly move up and down.

As a result, the distance between the clean rollers 330 and 340 is increased according to the thickness of the product, so that the product contacts the clean rollers 330 and 340 and foreign matter can be properly removed.

On the other hand, when the inside of the workplace is narrow, the operator can change the length, position and angle of the conveying module 200. The link arm 230 of the feed module 200 is provided with a link arm connector 240 so as to be angularly adjustable with respect to each other. Adjustable connection is possible.

As shown in FIG. 2, in a state where the conveying module 200 is installed horizontally, an operator can change a part of the conveying module 200 to an angle that is perpendicular to the downward direction as shown in FIG. 3 . An angle adjusting hole 242 formed in one of the link arms 230 and an angle adjusting hole 242 formed on the other link arm 230 of the link arm 230 And an angle fixing hole 244 formed in a direction orthogonal to the longitudinal direction is communicated. At this time, the angle between the angle adjusting hole 242 and the angle fixing hole 244 is 90 degrees with respect to the center of the rotating shaft 210.

In this state, the operator inserts the angle fixing member 246 through the angle adjusting hole 242 and the angle fixing hole 244. 3, since the part of the conveying module 200 is positioned in the vertical direction, the volume occupied by the product surface cleaning system 10 in the work space is reduced as the conveying module 200 is folded .

In this way, the length, height, and angle of the conveyance module 200 can be changed according to the internal situation of the workplace, thereby improving work efficiency.

9A, when the ring-shaped blower 520 of the suction module 500 sucks the foreign matter through the suction chamber 510, that is, in the direction of the arrow A shown in FIG. 9A, The air that has passed through the ring bellows 520 and passes through the inlet port 520a of the ring blower 520 and escapes to the discharge port 520b of the ring blower 520. The foreign matter is adsorbed to the filter 533, And is collected in the collection space 532.

At this time, the backwash valve 537 shields the foreign matter outlet 535 so that the foreign matter collected in the foreign matter collecting space 532 can not escape to the outside. When the discharge sensor 540 senses the pressure of the air, the controller C compares the pressure detected by the discharge sensor 540 with the pressure detected by the discharge sensor 540 in the storage unit 542 And determines whether the pressure value difference is out of the preset pressure range stored in the storage unit 542. [

At this time, if the difference in pressure value is out of the set pressure range, the controller C determines that the filter cleaning time point and generates a filter cleaning signal. Then, the filter cleaning signal of the controller C is transmitted to the speaker 544 to inform the user by sound.

At the same time, the back-flush valve 537 opens the foreign matter outlet 535 and shields the filter inlet 531a under the control of the controller C. [

A user who hears a sound connects the cleaning hose to the foreign matter outlet 535 and then presses the cleaning button (not shown) of the ring blower 520 to rotate the ring blower 520 in the reverse direction. When the ring blower 520 is rotated in the reverse direction, air flows in the direction of the arrow B shown in FIG. 9B through the discharge port 520b of the ring blower 520 and is discharged through the suction port 520a And the discharged air flows through the filter outlet 531b and passes through the filter 533. At this time, the foreign matter adsorbed on the filter 533 is separated from the filter 533, and is discharged through the foreign matter outlet 535 together with the foreign matter collected in the foreign matter collecting space 532. In this case, the foreign matter adsorbed on the filter 533 and the foreign substances collected in the foreign matter collecting space 532 are cleanly removed.

As described above, since the filter cleaning timing can be accurately known, the filter 533 can be cleaned at an appropriate time, and the driving of the ring blower 520 can be smoothly maintained, thereby improving the efficiency of the operation.
