5 is a block diagram schematically showing a control state of the controller 150, and FIGS. 6 and 7 schematically show an operating state of the probe 30 for measuring the upper and lower inner diameters of the bearing 5. Drawing.

First, the conveyor belt 93 is rotated by a drive member 93a such as a motor to convey the bearing 5 to be measured by the probe 30 in a predetermined direction as shown in FIG. And structures are not necessarily limited to the drawings.

Here, the sensor unit 95 is positioned on the conveyor belt 93. The sensor unit 95 is in contact with the bearing 5 which the conveyor belt 93 transfers, thereby allowing the conveyor belt 93 to be positioned. ) Detects the bearing (5) to be transferred.

In addition, the sensor unit 95 outputs a signal detecting the bearing 5 to the controller 150 as shown in FIG. 5.

In this case, the control unit 150 receives power from the power supply unit 153 to control the driving of the fourth cylinder 97 as shown in FIG. 5, and is driven by the control of the control unit 150. As shown in FIG. 4, the fourth cylinder 97 is extended in the front-rear direction so that the bearing 5 sensed by the sensor unit 95 may be located in the lower direction of the probe 30. The bearing 5 is moved from the conveyor belt 93 to the seating plate 91.

Here, at one end of the fourth cylinder 97, the fourth cylinder 97 allows the bearing 5 to move the bearing 5 to the seating plate 91 more easily. Is installed, but the shape and structure of the plate (97a of FIG. 4) is not necessarily limited to the drawings.

As such, when the bearing 5 is positioned in the lower direction of the probe 30 by moving from the conveyor belt 93 to the seating plate 91, the controller 150 may be configured as shown in FIG. 5. One cylinder 50 is driven.

As shown in FIG. 6, the first cylinder 50 driven by the controller 150 slides the movable plate 11 in the vertical direction. In this case, the first cylinder 50 is vertically provided on the pedestal 15. The probe 30 moves up and down in the upper inner diameter direction of the bearing 5.

The probe 30 swinging upward and downward in the direction of the upper inner diameter of the bearing 5 measures the size of the upper inner diameter of the bearing 5.

As described above, after the probe 30 measures the upper inner diameter of the bearing 5, the second cylinder 70 is driven by the controller 150 to provide the probe 30 as shown in FIG. 7. The pedestal 15 is slidably moved in the vertical direction. At this time, the probe 30 moves up and down in the lower inner diameter direction of the bearing 5.

The probe 30 swinging in the lower inner diameter direction of the bearing 5 measures the lower inner diameter of the bearing 5.

Here, the pedestal 15 provided with the movable plate 11 sliding upward and downward by the first cylinder 50 and the probe 30 sliding upward and downward by the second cylinder 70 are installed. ) Slides vertically along the cross roller guides 13 and 19 described above, so that the probe 30 may not shake during the process of measuring the upper and lower inner diameters of the bearing 5. This allows the probe 30 to measure the upper and lower inner diameters of the bearing 5 more precisely.

As described above, the bearing 5 may be moved by the first cylinder 50 and the second cylinder 70 to measure the upper and lower inner diameters of the bearing 5. ), The upper and lower inner diameter of the bearing (5) can be measured more easily.

On the other hand, an air cylinder may be used as the first cylinder 50 and the second cylinder 70, but if the air cylinder is used as the first cylinder 50 and the second cylinder 70, The movable plate 11 and the pedestal 15 for sliding the first cylinder 50 and the second cylinder 70 in the vertical direction may be slidably moved in the vertical direction at a faster and faster speed. do.

That is, since the first cylinder 50 and the second cylinder 70 made of a relatively inexpensive air cylinder or the like move the probe 30 quickly, the probe 30 causes the bearing 5 to move. The time required to measure the upper inner diameter and lower inner diameter of the can be significantly shortened compared to the prior art has the advantage that the workability can be greatly improved.

6 and 7, the lengths of the piston rods of the first cylinder 50 and the second cylinder 70 are located on the upper portion of the first cylinder 50 and the second cylinder 70. It is preferable that the height adjusting unit 170 to selectively adjust.

Here, the height adjusting unit 170 is to adjust the length of the piston rod of the first cylinder 50 and the second cylinder 70 in accordance with the height of the bearing (5), specifically, the bearing ( 5) when the height of the height adjustment unit 170 reduces the length of the piston rod of the first cylinder 50 and the length of the piston rod of the second cylinder 70 so that the probe 30 is the bearing The size of the upper and lower inner diameters of (5) can be measured more easily.

On the contrary, when the height of the bearing 5 is low, the height adjusting unit 170 increases the length of the piston rod of the first cylinder 50 and the length of the piston rod of the second cylinder 70 to prevent the probe. 30 makes it easier to measure the size of the upper and lower inner diameter of the bearing (5).

As described above, the height adjusting part 170 selectively adjusts the length of the piston rods of the first cylinder 50 and the second cylinder 70 according to the height of the bearing 5. Regardless of the height of the bearing 5 has the advantage that it is possible to more efficiently measure the upper and lower inner diameter of the bearing (5).

Through the above process, the probe 30 measures the size of the upper inner diameter and the lower inner diameter of the bearing 5, wherein the measured value measured by the probe 30 is previously displayed on the display unit 99. The input value is compared.

In detail, the display unit 99 measures the probe 30 when the probe 30 measures the bearing 5 in which the fourth cylinder 97 moves in the direction of the seating plate 91. An error is displayed by comparing the measured value with a pre-input value and at the same time, it is determined whether the bearing 5 is defective according to the displayed error.

For example, when the measured value measured by the probe 30 is within the tolerance range of the input value input to the display unit 99, the bearing 5 is determined as good quality, otherwise the probe 30 When the measured value measured is greater than or less than the tolerance range of the input value input to the display unit 99, the bearing 5 is determined as defective.

As such, the display unit 99 compares the measured value measured by the probe 30 with a pre-input input value to display an error and determines whether the bearing 5 is defective according to the displayed error. There is an advantage that it is easier to determine whether the bearing (5) is defective.

The bearing 5, which is determined by the display unit 99 to be defective, is moved left and right by the fifth cylinder 100 driven by the control unit 150, so that the sixth cylinder 130 of the sixth cylinder 130 is moved. It is located at one end.

In addition, the sixth cylinder 130 is driven by the controller 150 so that the bearing 5, in which the fifth cylinder 100 is moved in the left and right directions, is positioned on the conveyor belt 93 in a predetermined direction. The bearing 5 is moved from the seating plate 91 to the conveyor belt 93 so as to be transported again.

8 is a view schematically showing a state in which the outer diameter measuring unit 190 measuring the upper outer diameter and the lower outer diameter of the bearing 5 is selectively mounted on the pedestal 15, and FIGS. 9 and 10 show the outer diameter measurement. An enlarged view schematically showing an operating state of the unit 190.

Next, as shown in FIG. 8, an outer diameter measuring unit 190 for measuring an upper outer diameter and a lower outer diameter of the bearing 5 may be selectively mounted to the pedestal 15 by a fixing member such as a bolt. At this time, the shape and structure of the outer diameter measuring unit 190 is not necessarily limited to the drawings.

Here, the outer diameter measuring unit 190 includes a third cylinder 193 selectively mounted on the pedestal 15 as shown in FIGS. 9 and 10; And a probe 195 that moves in the left and right directions by the third cylinder 193 and measures an upper outer diameter and a lower outer diameter of the bearing 5.

More specifically, the probe 195 of the outer diameter measuring unit 190 is moved up and down by the first cylinder 50 and the second cylinder 70 described above, as shown in FIGS. 9 and 10. As described above, the contact with the upper outer diameter and the lower outer diameter of the bearing 5 is measured at the same time.

Here, the third cylinder 193 of the outer diameter measuring unit 190 is driven by the control unit 150 and its length is extended in the left and right directions, so that the probe 195 of the outer diameter measuring unit 190 is It is possible to contact the upper outer diameter and the lower outer diameter of the bearing (5).

As such, the outer diameter measuring unit 190 selectively mounted on the pedestal 15 has an advantage of being able to measure the upper outer diameter and the lower outer diameter of the bearing 5 as necessary.

FIG. 11 is a view schematically showing a state of the transfer unit 350 for rotating the bearing 5, which is determined to be defective, by rotating in the up and down direction, to the guide unit 300, and FIG. 12 is a view of the guide unit 300. A diagram schematically showing an operating state.

On the other hand, the bearing 5 determined as defective by the display unit 99 is discharged downward through the outlet (91a) formed in the seating plate (91).

More specifically, the bearing 5, which is determined to be good by the display unit 99, is moved to the left and right by the fifth cylinder 100 and positioned at one end of the sixth cylinder 130. On the contrary, the bearing 5, which is determined to be defective by the display unit 99, is moved left and right by the fifth cylinder 100, and the outlet 91 a formed in the seating plate 91 is moved. It is discharged downward through.

Here, the bearing 5 is rotated by a driving member 300a such as a motor driven by the controller 150 at the lower portion of the seating plate 91 and determined to be defective. And guide portion 300 for selectively guiding the storage case (310, 330) located on the left and right sides according to the tolerance range; A transfer part 350 which rotates in an up and down direction to transfer the bearing 5 determined as defective to the guide part 300 and to selectively open the discharge port 91a; The seventh cylinder 370 is driven by the controller 150 to rotate the transfer part 350 in the vertical direction.

First, an opening and closing portion 353 for selectively opening and closing the outlet 91a is formed at one upper portion of the transfer portion 350, and at the same time, the transfer portion 350 rotates upward and downward in the lower portion of the transfer portion 350. One end of the seventh cylinder 370 is axially coupled.

In this state, when the length of the seventh cylinder 370 is increased, the other side of the transfer part 350 rotates upward, and at the same time, the opening / closing part 353 formed at an upper portion of the transfer part 350 moves downward. It rotates to open the outlet 91a.

On the contrary, when the length of the seventh cylinder 370 is reduced, the other side of the transfer part 350 rotates downward and at the same time, the opening / closing part 353 formed on one side of the transfer part 350 rotates upward. It moves to close the outlet 91a.

Here, when the opening and closing part 353 opens the outlet 91a, the bearing 5 determined as defective by the display unit 99 is discharged downward through the outlet 91a and then the opening and closing part. It moves along the inclined surface of 353 and is conveyed to the guide part 300 as shown in FIG.

In addition, the bearing 5, which is determined as defective, transferred to the guide part 300, is guided to storage cases 310 and 330 located at left and right sides of the guide part 300, respectively, as shown in FIG. 12.

Here, the guide part 300 is selectively rotated by the driving member 300a to selectively guide the bearings 5, which are determined to be defective, to the storage cases 310 and 330 located on the left and right sides according to the tolerance range. Done.

More specifically, the bearing 5, which is determined to be defective because the measured value measured by the probe 30 exceeds the tolerance range of the input value input to the display unit 99, is right as shown in FIG. 12. Guided to the storage case 330 located in.

In contrast, the bearing 5, which is determined to be defective because the measured value measured by the probe 30 is less than the tolerance range of the input value input to the display unit 99, is located on the left side as shown in FIG. 12. The storage case 310 is guided.

Here, the guide portion 300 is rotated by the drive of the drive member 300a as shown in Figure 12 is inclined at an angle, so that the bearing case (5) determined to be defective in the storage case ( Selectively guided to 310, 330, respectively.

Here, when the bearing 5 is determined to be defective beyond the tolerance range is transferred to the guide portion 300, the driving member 300a is rotated in the forward direction by the control unit 150 to the guide portion ( Tilt 300) to the right.

As a result, the bearing 5 that is determined to be defective beyond the tolerance range is guided and stored in the storage case 330 located on the right side of the guide part 300.

On the other hand, when the bearing 5 which is determined to be defective because it is less than the tolerance range is transferred to the guide part 300, the driving member 300a is rotated in the opposite direction by the control part 150 so that the guide part ( Tilt 300) to the left.

As a result, the bearing 5, which is determined to be defective because it is less than the tolerance range, is guided and stored in the storage case 310 located on the left side of the guide part 300.

As described above, since the guide unit 300 selectively guides the bearing 5 determined as defective to the storage cases 310 and 330 located on the left and right sides according to the tolerance range, the guide unit 300 exceeds the tolerance range. There is an advantage that can be stored separately from the bearing 5 and the bearing 5 which is less than the tolerance range.

As described above, due to the probe being moved by the first cylinder and the second cylinder to measure the upper inner diameter and the lower inner diameter of the bearing, the parallelism of the bearing, that is, the upper inner diameter and the lower inner diameter of the bearing may be viewed. Since the first cylinder and the second cylinder, which can be easily measured and are relatively inexpensive, quickly move the probe, the time required for the probe to measure the upper and lower inner diameters of the bearing is increased. Compared with the related art, it can be significantly shortened, so that workability can be greatly improved.

The pedestal provided with the movable plate that is slidably moved up and down by the first cylinder and the probe that is slidably moved up and down by the second cylinder is slidably moved up and down along the cross roller guide. There is no fear that the probe may be shaken during the process of measuring the upper and lower inner diameters of the bearing, and thus, the probe may more accurately measure the upper and lower inner diameters of the bearing.

In addition, since the height adjusting unit selectively adjusts the lengths of the piston rods of the first cylinder and the second cylinder to match the height of the bearing, the probe has an upper inner diameter and a lower inner diameter regardless of the bearing height. There is an effect that can be measured more efficiently.

In addition, the outer diameter measuring unit selectively mounted on the pedestal has an effect of measuring the upper outer diameter and the lower outer diameter of the bearing as necessary.

In addition, the display unit compares the measured value measured by the probe with a pre-input input value and displays an error, and at the same time determines whether the bearing is defective according to the displayed error. It can work.

Further, since the guide portion selectively guides the bearings determined to be defective to the storage cases located on the left and right sides according to the tolerance range, the bearings that are greater than the tolerance range and the bearings that are less than the tolerance range can be stored separately. It has an effect.

In addition, the present invention is not limited to what has been described above and illustrated in the drawings, and of course, more modifications and variations are possible within the scope of the following claims.
