Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deburring apparatus for removing burrs generated on a plate-like work after cutting or punching, and more particularly, to a rotating device which rotates at a high speed during the transfer of the plate-like work. The present invention relates to a deburring apparatus for performing deburring of a workpiece using a brush.

[0002]

2. Description of the Related Art When a plate-shaped work such as a metal plate or a plastic plate is cut or punched, burrs are generated at a cut edge portion or a hole inner peripheral portion of the work. After this, a deburring step for removing burrs from the work is required. Various devices have been conventionally proposed as devices used in such a deburring process.
In general, a horizontal axis rotating brush type in which a rotating brush is rotated about a horizontal axis, a vertical axis rotating brush type in which a rotating brush is rotated about a vertical axis, or a combination of a plurality of these types are known. For example, in Japanese Patent Application Laid-Open No. H10-15798, a first deburring device that rotates a grindstone around a horizontal axis to remove burrs and a second deburring device that rotates a rotary brush around a vertical axis to remove burrs are disclosed. The third deburring device of the horizontal axis rotary grindstone type similar to the first deburring device is arranged in the transfer direction of the work, and the work conveyed by the transfer device sequentially passes through these deburring devices. The burrs of the work are removed.

As shown in FIG. 8 (b), a rotary brush of a conventional deburring device is configured such that a brush piece 80 formed by integrating the heads of a large number of linear brush materials is formed on a brush mounting plate 81. The heads of the brush pieces are connected to each other by a wire on the upper surface of the brush mounting plate 81 and fixed.
Therefore, all the brush pieces 80 are integrated, and only the individual brush pieces cannot be freely removed from the brush mounting plate.

[0004]

There has been proposed a conventional vertical-rotation brush-type deburring apparatus in which a plurality of vertical-rotation brushes are arranged in a staggered manner in the width direction. Since a plurality of brushes are mounted on an integral frame, when the height of the brushes needs to be adjusted with respect to the work, all the brushes are simultaneously adjusted in the same manner. Therefore, if the thickness of the work to be deburred is not uniform in the width direction of the transport path, the contact state of each rotating brush with the work differs depending on the position of the rotating brush. In such a case, the contact pressure on the work becomes excessively large, and the wear of the rotating brush is accelerated. On the other hand, the contact pressure is reduced, and there is a possibility that a portion where the burr is not removed is generated on the work. Also, when handling a work narrow in width relative to the width of the transport path, only a part of the rotating brushes arranged in the width direction comes into contact with the work, and the rotating brushes arranged in the width direction are arranged. Variations occur in the wear state between the two.

When a plurality of rotating brushes arranged in the width direction are non-uniformly worn and deburring of a wide workpiece is performed, the burrs are removed from a portion of the workpiece opposed to the worn rotating brush. The imperfections require frequent replacement of the rotating brush. On the other hand, even if a brush piece with little wear can be reused in a rotating brush, it is not possible to replace only a worn brush piece with a conventional rotating brush, so the entire rotating brush must be replaced, which is uneconomical. Met.

Accordingly, the present invention solves the above-mentioned problems in the prior art, and even when the thickness of the work is not uniform in the width direction of the transport path or when the width of the work is narrow, the present invention covers the entire work width. A deburring device that can uniformly and efficiently remove the burrs on the outer peripheral edge and the perforated portion, and does not require frequent replacement of the rotating brush, and a portion where the brush is partially worn, for example. It is an object of the present invention to provide a deburring device which can easily replace only a cartridge in a cartridge type and which can effectively use a consumable brush.

[0007]

A deburring apparatus according to the present invention, which can achieve the above object, comprises a plurality of elevating and lowering supporting plates which are individually supported on a supporting frame so as to be vertically adjustable. A plurality of brush spindles provided at least one for each elevating support plate, the upper end of which is rotatably supported on the elevating support plate about a vertical axis, and a rotating brush fixed to the lower end of each brush spindle; A drive source that rotationally drives each brush spindle, a plurality of transport rollers arranged in a transport direction for transporting the work by passing the workpiece under the rotary brush, and transport rollers at least in front and rear positions near the rotary brush A plurality of pinch rollers, which are arranged to face each other above and convey the work between the conveying rollers; And it is characterized in that it comprises a drive source for rotationally driving the fine pinch rollers in unison.

In the deburring apparatus, the brush spindle is divided into a plurality of groups each having at least three triangularly arranged spindles and supported by the lifting / lowering support plate. It is desirable that the height of the entire rotating brush can be adjusted simultaneously. It is also desirable that the distance between the pinch roller and the conveying roller can be adjusted.

A height adjusting screw shaft is rotatably supported on a vertical support plate around a vertical axis, and a lower portion of the height adjusting screw shaft is screwed to a receiving nut provided on a support frame. In addition, it is also desirable to provide a clamp mechanism for releasably restraining the rotation of the height adjustment screw shaft on the lifting support plate. Further, in this case, the clamp mechanism is fixed to an upper portion of the height adjustment screw shaft, and a clamp cylinder fixed to the lifting support plate so as to concentrically surround the outside of the height adjustment screw shaft. A ball retainer having a plurality of ball receiving holes radially provided from a central portion and having screw holes communicating with the ball receiving holes above the central portion; A plurality of clamp balls housed adjacent to each other in the ball housing hole, and a clamp shaft screwed into the screw hole and having a conical ball pressing portion protruding into the ball housing hole at the tip. It is desirable to have a configuration including

In the deburring apparatus of the present invention, the rotary brush is formed by converging a plurality of linear brushes made of a synthetic resin material mixed with an abrasive material one by one to form an engaging head. A brush plate having a plurality of clamp holes into which the brush plate fits and engages with the engagement head, and a clamp plate for detachably supporting the brush plate. An effective use of the rotating brush is achieved by detachably fixing the brush piece to a brush mounting plate provided at a tip end portion and making the brush piece arbitrarily replaceable.

Next, the work feeder will be described with reference to FIGS. The belt conveyor 4 includes a conveyor belt 42 having a flat conveyance surface, and a conveyor frame 3.
It is configured to be bridged between a carry-in belt pulley 43 whose both ends are rotatably supported on the side and a carry-out belt pulley that is hidden in the drawing. A driven sprocket 44 is fixed to one end of the unloading side belt pulley so as to rotate coaxially and integrally therewith. A driven chain 45 is stretched over the driven sprocket 44. The drive chain 45 is connected to the conveyor frame 3.
The rotation of the driving sprocket 47, which is rotationally driven by the motor 46 provided in the belt conveyor 4, is transmitted to the driven sprocket 44 via the guide sprocket 48, and the belt conveyor 4 is rotated.
Is driven.

The roller conveyor 5 has a number of transport rollers 49 arranged in the transport direction such that the upper surface is substantially at the same height as the transport surface of the transport belt 42. These transport rollers 49 are rotatably supported by bearings on both sides of the conveyor frame 3 as shown in FIG.
A driven sprocket 50 is fixed to one end of the shaft, a drive chain 45 is stretched over the sprocket 50, and is rotated by a motor 46 in synchronization with the transport belt 42. A guide sprocket 51 for ensuring engagement between the driven sprocket and the drive chain 45 is provided between the two transport rollers 49 on the upstream side in the transport direction close to the transport belt 42 side. Is provided rotatably.

Also, above the row of transport rollers 49, 4
Four pinch rollers 52 are disposed so as to face the transport rollers 49 at the respective locations. The pinch roller 52 has an outer peripheral surface formed of an elastic material such as rubber, and sandwiches the work conveyed by the belt conveyor 4 between the pinch roller 52 and the conveyance roller 49 to form a deburring unit 6 shown in FIG. Is configured to pass below the rotating brush 13.

These four pinch rollers 52 are rotatable via bearings at both ends thereof in a bearing holder 56 which is vertically movably fitted to guide frames 54 fixed to the left and right sides of the conveyor frame 3. It is supported by. Further, a plate 50, which is supported so that the vertical position can be adjusted by adjusting bolts 55, is fitted into the guide frame 54.
A spring 53 for adjusting the pinch roller pressure is provided between the bearing holder 56 and the bearing holder 56 to urge the bearing holder 56 downward to press the pinch roller against the roller.
Therefore, by rotating the adjustment bolt 55 according to the thickness of the work, the plate moves up and down, the spring pressure is adjusted, and the pressing force of the pinch roller can be adjusted. Therefore, the pinch roller can have a large thickness adjustment range as compared with the case where no spring is interposed.

As shown in FIG. 6, a driven sprocket 57 is fixed to the end of each pinch roller 52 protruding from one bearing 53. These driven sprockets 57 include a guide sprocket 58 and an interlocking sprocket (not shown) fixed to the transport roller on the side opposite to the side on which the driven sprocket 44 of the unloading belt pulley of the belt conveyor 4 is mounted. The drive chain 59 is stretched.

That is, the drive chain 59 and the drive chain 45 are provided on opposite sides of the width direction of the conveyor frame 3, and are driven by the motor 46 so that the transport belt 42, the transport rollers 49, and All of the pinch rollers 52 work together so that the work conveyed from the left side of FIG. 5 onto the conveyor belt 42 passes from the conveyor belt 42 between the conveyor roller 49 and the pinch roller 52 and is sent to the right side in FIG. Has become.

The deburring machine 1 configured as described above controls the motors 36 and 39 for driving the rotating brush 13 of the deburring unit 6 to rotate by the control panel (not shown) and transports the belt conveyor 4. The control of the motor 46 for synchronously driving the belt 42, the transport roller 49 of the roller conveyor 5, and the pinch roller 52 is performed.

As shown in FIGS. 7 and 8, the rotary brush 13 in the deburring apparatus of this embodiment is configured such that the brush pieces can be easily replaced in a cartridge type. That is, the brush piece 61 of the present embodiment forms a large diameter engaging head 62 by converging a large number of one sides of a linear brush material made of a synthetic resin material mixed with an abrasive material. Part 62
Can be fitted and locked in a clamp hole 65 formed in the clamp plate 64. Clamp plate 64
As shown in FIG. 7B, a plurality of clamp holes 65 are formed at equal pitches on a brush pitch circle, and a plurality of bolts 67 for screwing the clamp plate to a brush mounting plate 68 are screwed inside. An attachment hole 66 is formed. As shown in FIG. 8A, the clamp hole 65 is formed in a step shape so as to hold the engaging head 61 of the brush piece 61 completely buried and not to fall off. Therefore, the brush piece 61 is held by simply fitting the brush piece 61 from the tooth tip into the clamp hole of the clamp plate.
7, each brush piece becomes a clamp plate 6.
4 and the brush mounting plate 68 can be completely clamped.

When the rotary brush is to be replaced, the clamp plate 64 can be removed by removing the bolt 67 and replaced with a new one. When only a part of the brush is worn, only the brush is removed from the clamp hole 65 and can be replaced with a new brush, so that it is not necessary to replace the entire rotating brush, which is economical. It is. Also, depending on the type of deburring, the brush edge of the entire rotating brush is not uniform in length,
For example, there are cases where it is good to alternately arrange long and short tooth tips. However, since the brush piece is of a cartridge type, such a case can be easily handled.

The deburring apparatus of the present embodiment is configured as described above, and performs a work for deburring a work as follows. First, before performing the deburring operation, the distance between the conveying roller 49 and the pinch roller 52 is set in advance according to the thickness of the work, and the height of the rotating brushes of the three groups is adjusted appropriately according to the thickness of the work. Support frame 1 so that it comes to a position
Perform height adjustment of 0. Further, when the thickness of the work is different in the width direction, the operation handle 26 is rotated so that the lower end of the rotating brush 13 is at an appropriate position for deburring the work as necessary. Make adjustments for each group.

In this case, when the width of the work is smaller than the maximum width that the deburring machine 1 can handle,
One or two adjacent lifting plates 16, 17, 18 can be pulled up and only the rotating brush 13 corresponding to the work width can be used.

When the preparation is completed, the belt conveyor 4 and the roller conveyor 5 are driven and the rotating brush 1
The work 3 is driven to carry the work into the belt conveyor 4. The work put into the belt conveyor 4 is sent to the roller conveyor 5 side on the conveyor belt 42, and is further sandwiched between the conveyor roller 49 and the pinch roller 52 and is sent below the rotating brush 13. Here, the burrs of the work are removed by the rotating brush 13, but during this time, the work is sandwiched between the conveyance roller 49 and the pinch roller 52 and sent, so that the work rotates in the conveyance direction, The work that has passed under the rotating brush 13 without being flipped off by the rotating brush 13 and has been deburred is transferred to the transport roller 40 and the pinch roller 5 at the most downstream end in the transport direction.
2 is sent out to the right in FIG.

In this embodiment, the roller conveyor 5
A belt conveyor 4 is provided upstream of the belt conveyor. However, the belt conveyor 4 may be separate from the deburring machine 1 and has a structure in which a work is directly carried into the roller conveyor 5 without using the belt conveyor 4. You may.

As described above, according to the deburring apparatus of the present embodiment, the plate-like work for deburring is transported below the rotary brush by being sandwiched by the transport roller and the pinch roller driven simultaneously. While the work is in contact with the rotating brush, at least one of the pinch rollers before and after the work is sandwiching the work, so that the direction of the work does not rotate during burr removal, and the burr is surely and accurately formed. I can take it. In addition, the rotating brushes are arranged in a zigzag shape so as to block at least the entire width of the work and prevent the brush from leaking, so that the four peripheral edges of the work can be deburred and opened in one process. Deburring work of the hole can be performed at the same time.

Further, by adjusting the height of each lifting support plate, the height of the rotating brush can be adjusted for each group of rotating brushes having a brush spindle supported on each lifting support plate, and the width can be adjusted. When deburring workpieces having different thicknesses in different directions, the height of the rotating brush can be changed in the width direction of the workpiece (perpendicular to the transport direction) to equalize the state of contact of the rotating brush with the workpiece. . Similarly, even when the thickness of the work in the width direction is uniform, the variation in the lower end position due to the wear of the rotating brushes arranged in the width direction can be made uniform by adjusting the individual lifting support plates. Since the height adjustment of the lifting support plate can be performed by attaching an operation handle etc. to the height adjustment screw shaft and rotating it,
Easy to adjust. The rotation of the height adjustment screw shaft can be securely fixed at an arbitrary rotation position by the clamp mechanism, so that the adjusted brush position is not inadvertently displaced. .

As described above, one embodiment of the present invention has been described in detail. However, the present invention is not limited to the above-described embodiment, and various design changes can be made within the technical idea.
The present invention is particularly effective as a deburring device for a thin metal plate whose work is thin. However, by appropriately selecting a rotating brush, the present invention is also effective as a deburring device for not only a thin metal plate but also a thick metal plate. Further, the present invention can be applied not only to a metal plate but also to a deburring device for a glass plate, a plastic plate, and a ceramic plate. Further, the shape of the work is not limited to a square, and a deburr of an appropriate shape such as a disk can be used.

[0042]

As described above, according to the first aspect of the present invention, the height of the rotating brush is independently adjusted for each group of rotating brushes whose upper ends are rotatably supported by the respective lifting support plates. Since the adjustment can be performed, burrs can be satisfactorily removed even when the thickness of the work varies in the width direction. If only a part of the rotating brushes is worn due to deburring work of a narrow width workpiece, the height of the lifting and lowering support plate is individually adjusted so that the position of the lower end of the entire rotating brush can be almost adjusted. Because they can be evenly aligned,
There is no need to frequently change the rotating brush.

According to the second aspect of the present invention, when the thickness of the work to be handled is changed, the height of the rotary brush can be easily adjusted to an appropriate value without individually adjusting the height of the lifting support plate. Position can be adjusted. According to the third aspect of the present invention, the distance between the pinch roller and the conveying roller can be adjusted, so that a wide variety of works having various thicknesses can be accommodated. Furthermore, according to the fourth aspect of the present invention, the position of the lifting support plate with respect to the support frame can be precisely adjusted, and there is no possibility that the adjustment position will be deviated by vibration or the like after the adjustment, and the height of the rotating brush can be adjusted with high precision Positioning can be performed.

Further, according to the fifth aspect of the present invention, the rotation of the height adjusting screw shaft is performed by pressing the clamp ball housed in the ball retainer against the inner peripheral surface of the clamp cylinder by screwing the clamp shaft. Since the clamp ball can be fixed at an arbitrary position and the clamp ball can be frictionally fixed to the inner peripheral surface of the clamp cylinder with a large force, the rotation of the height adjusting screw shaft can be reliably prevented. Further, according to the invention of claim 8, since only a portion such as when abrasion occurs can be easily replaced in a cartridge type, the brush which is a consumable item can be used effectively, and it is economical. is there.
