Abstract

<P>PROBLEM TO BE SOLVED: To provide a surface treatment brush capable of applying uniform surface treatment to an object having irregularities with a simple constitution, and saving a material. <P>SOLUTION: A large number of brush bodies 58 are intermittently arranged on the surface of a roller 56 of a rotary brush 50A. Substantially ring-shaped grooves 56A and ridges 56B, which are tilted relative to the direction of the axis of the roller 56, are formed on the roller 56. The brush bodies 58 are formed by fixing strip-like pieces of sand paper 59 by strings 60 and the like to grooves 56C formed in the grooves 56A. Side faces of each groove 56A function as flanges for holding the base of each piece of sand paper 59. Because the tilted brush bodies 58 are intermittently arranged, uniform surface treatment can be applied to the object having irregularities without arranging the brush bodies 58 on the entire surface of the roller 56. This enables partial replacement of the brush bodies 58 to save the material. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a brush for performing surface treatment such as removal of burrs generated during processing of a molded product or surface polishing, and more specifically to a rotary surface treatment brush.

  A film or foil is widely provided on the surface of a molded article such as a synthetic resin for the purpose of improving decoration and functionality. There are various methods for forming a coating on such a molded product, such as a method of simultaneously molding a resin product and contacting the coating, such as transfer molding and in-mold molding. In many cases, burrs are generated on the surface edge of the product. Moreover, not only a resin molded product but a burr | flash generate | occur | produces in an edge part also in the process of processing a sheet metal processed material, for example. If burrs remain, the appearance of the molded product will deteriorate, so it must be removed. At present, mainly (1) manual removal using grinder, belt sander, file, etc., (2) fixing the object to be processed and removing polishing tool (or jig) such as belt sander attached to the robot (3) Technology such as a flat surface deburring machine mainly for the purpose of deburring a flat surface.

The plane deburring machine according to (3) has a rotating brush structure in which a plurality of (for example, 4 to 6) brushes rotating in a horizontal plane are arranged with respect to a rotating shaft standing perpendicular to the plane. And some burr on the protruding part can be removed. Such flat deburring techniques include, for example, “a method for sanding the surface of a workpiece” described in Patent Document 1 below, and “a method for deburring a product, particularly a metal product, and its method described in Patent Document 2”.

The lower frames 18A to 18D are provided with casters 148 so that the entire deburring device 10 can be moved. In the main body frame 12, an upper conveyor 28 and a lower conveyor 34, a pair of rotating brushes 50A and 50B, a drop guide 42 for feeding the workpiece W from the upper conveyor 28 to the lower conveyor 34, and the rotating brushes 50A and 50B are rotated. Motors 84A and 84B for driving are housed or supported. Also, the lifting frames 52 and 54 for supporting the rotating brushes 50A and 50B, the motors 132 and 142 for raising and lowering the lifting frames 52 and 54, and the outputs of the motors 84A and 84B are transmitted to the rotating brushes 50A and 50B. A belt transmission mechanism for adjusting the tension of the belt and a tension adjusting mechanism 106 for adjusting the tension of the belt are also provided in the main body frame 12.

  As shown in FIGS. 1A and 1B, the main body frame 12 includes a front-side upper cover 20A, a front-side lower cover 20B, a rear-side upper cover 22A, a rear-side lower cover 22B, side covers 24A and 24B, The position is appropriately covered by the upper cover 26. Here, the front side refers to the front (or exit side) of the workpiece W in the transport direction, and the back side refers to the rear (or inlet side) in the transport direction. As shown in FIG. 4A, the side cover 24B is formed with a window 25 for checking the rotating brushes 50A and 50B from the outside, and the window 25 is provided with a transparent cover 25A. ing. By providing such a window 25, the degree of reduction of the rotating brushes 50A and 50B can be confirmed, and the brush replacement time can be easily understood. In addition, the main body frame 12 is formed with appropriate positions such as an inlet (inlet) for the workpiece W and an opening serving as a discharge port.

  The upper conveyor 28 is attached to a guide frame 29 (see FIGS. 2 and 4B) fixed to the auxiliary frames 36A to 36D of the main body frame 12 in a substantially horizontal direction. The upper conveyor 28 is for conveying the workpiece W in the direction indicated by the arrow F1a in FIG. 2, and its conveyance mechanism is known. In the present embodiment, the upper conveyor 28 is provided with a small driving motor 28A on the discharge side (left side in FIG. 2), and is entirely detachable from the guide frame 29. In this embodiment, the transport surface 30 of the upper conveyor 28 has a large number of round holes 32A and long holes for attracting and holding the work W on the transport surface 30 as shown in FIG. 32B is formed. Furthermore, as shown in FIG. 6 (C), the decompression chambers 150A and 150B formed inside the transfer surface 30 are connected to the decompression device 160 via a hose 156 connected to the suction ports 152A and 152B. (See FIG. 1), the inside of the pressure reducing device 160 is decompressed.

  In this embodiment, as shown in FIGS. 6B and 6C, honeycomb structures 154A and 154B are provided above the decompression chambers 150A and 150B, that is, below the round holes 32A and the long holes 32B. It has been. The honeycomb structures 154A and 154B are arranged so that the air passages are in a substantially vertical direction, and thereby, the flow of suction is rectified so as to straighten from the upper part to the lower part, and the suction force is improved. At the same time, the sound generated during suction is suppressed. With the configuration as described above, the workpiece W placed on the transport surface 30 is sucked and held in the round hole 32A and the long hole 32B, and a positional deviation occurs during the deburring process by the rotating brushes 50A and 50B. There is nothing. The round hole 32A is, for example, about φ4 mm, and the long hole 32B is formed, for example, about 4 mm × 7 mm. By combining such holes having different shapes, the workpiece W can be favorably adsorbed from a large to a small case.

  On the other hand, the lower conveyor 34 is attached to a guide frame 35 (see FIGS. 2 and 4B) fixed substantially horizontally to the auxiliary frames 36A to 36D. The lower conveyor 34 is installed below the upper conveyor 28 at a predetermined interval, and is used to send back the workpiece W that has been deburred in the direction indicated by the arrow F1b in FIG. . The transport mechanism of the lower conveyor 34 is also known in the same manner as the upper conveyor 28. Further, a small motor 34A for driving is provided at the side end of the discharge side (right side in FIG. 2) when the workpiece W is fed back, and the whole is detachable from the guide frame 35.

  A drop guide 42 for sending the workpiece W to the lower conveyor 34 is provided in front of the conveying direction of the upper conveyor 28 as described above. The drop guide 42 includes a pair of substantially V-shaped arms 44A and 44B attached to end side surfaces of the upper conveyor 28 and the lower conveyor 34, a slope 46 that receives the workpiece W that has passed through the upper conveyor 28, and the workpiece The stopper 48 is used to prevent the W from falling off. The slope 46 is provided with the stopper 48 at one end and is connected to the lower conveyor 34 at the other end. The stopper 48 is set to have a height substantially equal to the conveying surface 30 of the upper conveyor 28. By providing the drop guide 42 having such a configuration, the workpiece W that has passed through the upper conveyor 28 falls along the slope 46 and is sent to the lower conveyor 34.

  Next, the rotating brushes 50A and 50B and their support mechanisms will be described. The rotating brushes 50A and 50B are arranged so as to be substantially orthogonal to the conveying direction of the workpiece W, and are supported by elevating frames 52 and 54 provided in the main body frame 12. Since the support mechanisms of the rotary brushes 50A and 50B are basically the same, the rotary brush 50A will be described below as an example. As shown in FIGS. 3, 7, and 8, the rotating brush 50 </ b> A has a large number of brush bodies 58 on the surface of a substantially cylindrical roller 56, and both ends have attachment surfaces 52 </ b> A and 52 </ b> B of the elevating frame 52. Are rotatably supported by bearings 62 and 72 provided on the surface. As shown in FIG. 7B, the roller 56 has a hollow portion 66 provided with a groove 66A having a substantially square cross section along the axial direction at a substantially central portion. As shown in FIGS. 7B and 7C, the hollow portion 66 can accommodate a substantially cylindrical insert 68 having a convex key 68A that engages with the groove 66A. The inner body 68 can be rotated together with the roller 56 by the engagement between the key 68A and the groove 66A.

  Here, a shaft 64 provided with a flange 65 is rotatably supported by one of the bearings 62, and when a portion at the tip of the flange 65 is inserted into the hollow portion of the insert 68, the shaft A protrusion provided on 64 and a groove (both not shown) formed in the insert 68 are engaged, so that the roller 56 and the shaft 64 can rotate together. A rotating shaft 74 is rotatably supported by the other bearing 72, and an outer cylinder 76 having a flange 77, convex keys 78 A and 78 B, and a fastening rod 80 on the outer peripheral surface of the rotating shaft 74. Is provided. Screw portions 74A and 76A are formed on the outer peripheral surface of the rotating shaft 74 and the inner peripheral surface of the outer cylinder 76. In this embodiment, the screw portion 74A is a male screw, and the screw portion 76A is a female screw. It is a screw. When the outer cylinder 76 is rotated by the operation of the fastening rod 80, the outer cylinder 76 can be slid along the rotation shaft 74. On the other hand, key grooves 70A and 70B that can be engaged with the keys 78A and 78B of the outer cylinder 76 are formed at the end of the inner insert 68 accommodated in the hollow portion 66 of the roller 56. For this reason, when the outer cylinder 76 is slid until the keys 78A and 78B are fitted in the key grooves 70A and 70B by the operation of the clamping rod 80, the rotation of the rotating shaft 74 causes the outer cylinder 76 and the inner insert 68 to move. The rotation shaft 74 and the roller 56 rotate as a unit. The screw portions 74A and 76A are screwed in the direction opposite to the rotation direction of the rotating brush 50A to prevent loosening of the brush.

  Here, the structure of the rotating brush 50A will be described with reference to FIG. As shown in FIG. 8A, the rotating brush 50A has a large number of brush bodies 58 arranged on the surface of the roller 56 at a predetermined interval. In this embodiment, as shown in FIG. 8B, the roller 56 has a recess 56A inclined at a predetermined angle with respect to a surface (surface indicated by a dotted line in the drawing) substantially orthogonal to the axial direction of the roller 56. A plurality of convex portions 56B are formed in a substantially ring shape. In this embodiment, a strip-shaped sandpaper 59 is used as the brush body 58, and a string 60 is passed through a folded portion of the sandpaper 59 to be wound and fixed to a groove 56C formed in the recess 56A. . That is, the pair of side surfaces 57A and 57B of the concave portion 56A act as a flange that grips the root of the sandpaper 59, and prevents the root of the sandpaper 59 from breaking. In this embodiment, as shown in FIG. 8B, since the side surfaces 57A and 57B of the groove 56A are inclined with respect to the surface substantially perpendicular to the axial direction, the sandpaper 59 is also the roller 56. It is inclined with respect to the axis.

  Next, a case where a three-dimensional workpiece having the rising portion 300 is machined like the workpiece W shown in FIG. If a rotating brush 310 having a sandpaper 314 fixed in a direction substantially perpendicular to the axis of the roller 312 is used as shown in FIG. 10 (B), the sandpaper is used as shown in FIG. 10 (C). Since the tip 314A of 314 does not hit the burr 302 formed on the side surface of the rising portion 300, it cannot be deburred. Further, since there is a gap between the sandpapers 314 and the gaps do not hit the workpiece W and cannot be deburred, the sandpaper is rotated by rotating the rotating brush 310 in the direction of the arrow F10a or swinging in the direction of the arrow F10b. It is necessary to apply 314 to the workpiece W. On the other hand, when the rotating brush 50A of the present embodiment is used, the sandpaper 59 having an angle rotates obliquely, so that the tip 304 contacts the burr 302 as shown in FIG. The rising part 300 can be deburred.

  In this way, by disposing the inclined brush body 58 intermittently, even if the workpiece W includes irregularities, the surface treatment can be uniformly performed without providing the brush body 58 on the entire surface of the roller 56. it can. Further, when the brush body 58 is worn, only a necessary part of the brush body 58 can be removed from the recess 56A and replaced with a new brush body 58, so that waste of material can be saved. If the tip of the sandpaper is used with both corners sharp like the sandpaper 59D shown in FIG. 8 (D), the surface of the workpiece W is likely to be damaged, so that the sandpaper 59, 59A, 59B, 59C As shown in the figure, it is preferable to use a shape with a corner cut off. The illustrated example is an example, and the brush body 58 may be formed using a material other than the sandpaper 59.

  The other rotating brush 50B has basically the same configuration, but in this embodiment, the rotating brush 50A on the entrance side of the workpiece W is approximately 7 with respect to a surface substantially orthogonal to the axis of the roller 56. It is set so that the angle of the rotary brush 50B on the exit side of the workpiece W is inclined by about 20 degrees. When the angle of the rotating brush is set in this manner, the planar brush portion of the workpiece W is well deburred with the rotating brush 50A on the entrance side, and the uneven portion (three-dimensional portion) of the workpiece W with the rotating brush 50B on the outlet side. Deburring is performed well.

  Here, the inclination of the sandpaper 59 will be described. If the angle α (see FIG. 9A) of the sandpaper 59 with respect to the surface orthogonal to the axis of the roller 56 is smaller than 5 degrees, for example, the width that the sandpaper 59 can rub the workpiece W becomes narrow. The width D of the convex portion 56B must be reduced. However, for example, when foamed polystyrene or the like is used as a material constituting the roller 56, if the width D of the convex portion 56B is narrow, the thickness is insufficient and the convex portion 56B is likely to be broken. Therefore, by setting the inclination angle α of the sandpaper 59 to, for example, 5 degrees or more to increase the surface-treatable area, the width D can be increased to some extent to make it difficult to break the convex portion 58B.

  As shown in FIG. 9B, when the rotary brush 50A is formed by connecting a plurality of roller units 200A to 200C in the axial direction, the sandpaper 59 provided on the surface of the roller units 200A to 200C When the inclination is small, a gap I is generated between the sandpapers 59 in the vicinity of the connection surface 202 between the roller units, and the surface treatment cannot be performed at that portion. On the other hand, as shown in FIG. 9C, when the inclination of the sand paper 59 is large to some extent (for example, 7 degrees or more), there is no gap near the connection surface 202, so the surface of the workpiece W is uniform. Can be processed. Of course, when the rotary brushes 50A and 50B are constituted by one roller without connecting a plurality of roller units, the inclination angle α of the sandpaper 59 may be about 5 degrees.

  Next, the rotation drive mechanism of the rotary brushes 50A and 50B will be described. A fixing plate 82 is provided on the lower frame 18B side of the main body frame 12 over the other lower frames 18A and 18C. On the fixed plate 82, motors 84A and 84B are provided for rotating the rotary brushes 50A and 50B independently of each other. Pulleys 88A and 88B for hanging the belts 90A and 90B are provided at the ends of the output shafts of the motors 84A and 84B. On the other hand, the rotating shaft 74 supported by the bearings 72 of the elevating frames 52 and 54 passes through the fixing plates 52B and 54B on the side surfaces of the elevating frames 52 and 54, and the belts 90A and 90B are disposed at the ends thereof. Pulleys 86A and 86B are provided.

  Covers 96A and 96B covering the pulleys 86A and 86B are fixed to the side surfaces of the elevating frames 52 and 54 on the opposite side of the rotating brushes 50A and 50B. On the bottom surfaces of the covers 96A and 96B, slit-shaped openings 98A and 98B for passing the belts 90A and 90B are formed. Further, hollow expandable covers 94A and 94B that can be expanded and contracted are attached to the bottom surfaces of the covers 96A and 96B. The telescopic covers 94A and 94B are fixed to a fixing plate 92 on auxiliary frames 38 and 39 provided at appropriate positions on the side frames 14B and 14C. Further, another fixing plate 93 is fixed to the side frames 14B and 14C above the covers 96A and 96B. Between the fixed plate 93 and the lower fixed plate 92, both ends of the telescopic covers 94A and 94B and the columns 100A, 102A, 100B, and 102B penetrating the covers 96A and 96B are fixed. The bottom ends of the covers 96A and 96B are fixed to lower ends of substantially cylindrical receiving portions 104A, 105A, 104B, and 105B through which the columns 100A, 102A, 100B, and 102B are slidably penetrated.

  The covers 94A and 94B and the expansion covers 96A and 96B are for preventing chips and dust generated during the surface treatment from being applied to the motors 84A and 84B. When the elevating frames 52 and 54 are moved up and down by a mechanism to be described later, the bellows-like expansion and contraction covers 94A and 94B expand and contract, so that the covers 96A and 96B fixed to the elevating frames 52 and 54 also move up and down. It is possible to do. In addition, the raising / lowering at this time is guided by the receiving portions 104A, 105A, 104B, and 105B sliding along the support columns 100A, 102A, 100B, and 102B.

  In this embodiment, since the elevating frames 52 and 54 are raised and lowered by an elevating mechanism which will be described later, the belts 90A and 90B of the belt transmission mechanism described above may be loosened. In this embodiment, the main body frame 12 is provided with a tension adjusting mechanism 106 as shown in FIGS. 4 and 11, thereby adjusting the tension of the belts 90A and 90B appropriately. The tension adjusting mechanism 106 has a structure in which a plurality of rollers are provided on a fixed plate 108 whose upper and lower edges are fixed to auxiliary frames 39 and 41 on the side frames 14B and 14C side. More specifically, four holders 112A to 112D are arranged in the vertical direction at a substantially central portion of the fixed plate 108, and the arms 114A provided with rollers 116A to 116D at the tips of the holders 112A to 112D. ˜114D is slidably stored. The arms 114A to 114D are slidable by a known reciprocating mechanism provided in the holders 112A to 112D, and the belts 90A and 90B are pressed by pressing the rollers 116A to 116D against the belts 90A and 90B. The tension is kept properly. The fixing plate 108 is also provided with other rollers 110A to 110D. In this embodiment, the tension of the belt 90A is adjusted by the rollers 110C, 116B, 116D, and 110D, and the tension of the belt 90B is adjusted by the rollers 110A, 116A, 116C, and 110B.

  Next, the lifting mechanism of the lifting frames 52 and 54 will be described. Fixed plates 52C and 54C are provided above the elevating frames 52 and 54 along the conveying direction of the workpiece W. The lower ends of cylinders 122 and 124 installed in a substantially vertical direction are fixed to the substantially central portions of the fixing plates 52C and 54C by appropriate means. On the outer peripheral surface on the upper end side of the cylinders 122 and 124, a rack (not shown) is intermittently formed in the axial direction. On the other hand, a support plate 120 is provided between the upper frames 16 </ b> A and 16 </ b> C of the main body frame 12. On the support plate 120, receiving portions 126 and 136 are provided at positions corresponding to the cylinders 122 and 124.

  First, the receiving portion 126 will be described. The receiving portion 126 rotatably supports a shaft 128 having a gear (not shown) that meshes with the rack of the cylinder 122 and covers the upper portion of the cylinder 122. A hollow cylindrical portion 126A is provided in a substantially vertical direction. A pulley 128A is provided at one end of the shaft 128. On the other hand, a motor 132 is fixed on the support plate 120, and a belt 130 hangs between a pulley 134 A provided at the tip of an output shaft 134 of the motor 132 and a pulley 128 A of the shaft 128. Is done. When the output of the motor 132 is transmitted to the shaft 128 via the belt 130 and rotated, the gear of the shaft 128 (not shown) and the rack of the cylinder 122 mesh with each other so that the cylinder 122 moves up and down. As the cylinder 122 moves up and down, the lifting frame 52 and the rotating brush 50A fixed to the cylinder 122 move up and down.

  The other receiving portion 136 has the same configuration, and includes a receiving portion 136A that slidably receives the cylinder 124, and a shaft 138 that includes a gear (not shown) that meshes with a rack formed in the cylinder 124. Is supported rotatably. Then, a belt 140 is wound around the pulley 138A at the tip of the shaft 138 and the pulley 144A at the tip of the output shaft 144 of the motor 142 provided on the support plate 120, whereby the output of the motor 142 is transferred to the cylinder. 124, the elevating frame 54 and the rotating brush 50B can be raised and lowered.

  By the way, a suction port 146 for collecting chips or dust generated by the surface treatment is attached to the support plate 120 by a support portion 146A. The suction port 146 is connected to the decompression device 160 via a hose 158 as shown in FIG. That is, in the present embodiment, the decompression device 160 serves as a decompression means for decompressing the inside of the upper conveyor 28 and a decompression means for collecting dust. In the present embodiment, the suction port 146 is provided above the butted portion of the pair of rotating brushes 50A and 50B. However, the position of the suction port 146 may be changed as necessary.

  Next, the operation of this embodiment will be described. First, the rotating brushes 50A and 50B are attached to the bearings 62 and 72 of the elevating frames 52 and 54 by the method described above. Next, the motors 84A and 84B are driven to rotate the rotary brush 50A on the entrance side of the workpiece W in the direction indicated by the arrow F7a in FIG. 4, and the rotary brush 50B on the exit side of the workpiece W is shown in FIG. It is driven to rotate in the direction indicated by arrow F7b. Further, the lifting motors 132 and 142 are driven according to the shape of the workpiece W, the presence or absence of unevenness, the size of the unevenness, and the like, and the heights of the rotating brushes 50A and 50B are adjusted. Further, the tension of the belts 90A and 90B is adjusted by the tension adjusting mechanism 106 according to the height of the rotating brushes 50A and 50B. Then, the motors 28A and 34A of the upper conveyor 28 and the lower conveyor 34 are energized, the upper conveyor 28 is driven in the direction indicated by the arrow F1a in FIG. 2, and the lower conveyor 34 is driven in the direction indicated by the arrow F1b in FIG. . The decompression chambers 150A and 150B in the upper conveyor 28 are decompressed by the decompression device 160 so that the workpiece W on the transport surface 30 of the upper conveyor 28 can be sucked and held by the round holes 32A and the long holes 34B.

  In this state, when the work W is placed on the upper conveyor 28, the work W is attracted and held by the round holes 32A and the long holes 32B provided in the transport surface 30, and moves in the direction of the arrow F1a, and the rotary brush 50A and Pass under 50B. At this time, the brush body 58 of the rotating brushes 50A and 50B hits the surface of the workpiece W to perform deburring. In addition, even when the workpiece W is uneven, as shown in FIG. 10D, the tip 304 of the sandpaper 59 contacts the burr 302 on the side surface of the rising portion 300, so that deburring can be performed satisfactorily. it can. Further, if the unevenness is up to about 100 mm, the tip of the brush body 58 comes into contact with a desired portion by changing the height of the rotary brush 50A or 50B, so that deburring can be performed. When the deburred workpiece W passes through the upper conveyor 28, it is sent to the lower conveyor 34 along the slope 46 of the drop guide 42, and is sent back by the lower conveyor 34 in the direction opposite to the conveying direction of the upper conveyor 28.

  Chips and dust generated during the processing as described above are gathered at these butted portions because the two rotating brushes 50A and 50B rotate in the opposite directions. For this reason, if collected chips and the like are collected from the suction port 146 provided above via the hose 158 connected to the pressure reducing device 160, scattering to the surroundings can be minimized. Note that the heights of the rotating brushes 50A and 50B can be arbitrarily changed by the above-described lifting mechanism even during processing (during rotation). When the rotary brushes 50A and 50B are replaced, the engagement between the keys 78A and 78B and the roller 56 is released by turning the fastening rod 80 of the outer cylinder 76 and sliding the outer cylinder 76 toward the receiving portion 72. Therefore, the rotary brushes 50A and 50B can be removed without using a tool. When the brush body 58 of the rotating brush 50A or 50B is not visible due to the support fitting when viewed from the window 25 of the side cover 24B, it is determined that the brush body 58 is worn and replaced. This is an example, and may be exchanged at other timing as necessary.

Thus, according to the first embodiment, there are the following effects.
(1) A large number of brush bodies 58 inclined at a predetermined angle with respect to the axial direction of the roller 56 are provided on the outer peripheral surface of the roller 56 in a substantially ring shape inclined with respect to the axial direction at predetermined intervals. The base side of the brush body 58 is gripped by the side surfaces 57A and 57B of the concave portion 56A formed in the roller 56 so that the tip end side is exposed for a predetermined length. However, the surface treatment can be performed uniformly and the waste of materials can be eliminated. Further, by providing the brush body 58 intermittently, it is possible to replace only a desired portion of the brush body 58.

(2) The lifting brushes 52A and 50B, which are rotatably supported so as to be substantially orthogonal to the conveying direction of the workpiece W, are used for raising and lowering the frame 52 without using a tool by using uneven fitting and threaded screwing. And 54 can be attached to and detached from each other, so that the rotating brushes 50A and 50B can be easily replaced.
(3) Since the height of the rotary brushes 50A and 50B is adjusted according to the shape of the workpiece W, the presence or absence of irregularities, and the dimensions thereof, processing can also be performed on the three-dimensional workpiece W having irregularities. it can. Further, the height may be adjusted according to the degree of wear of the brush body 58 of the rotating brushes 50A and 50B.

  (4) Since the conveying surface 30 of the upper conveyor 28 is provided with a large number of round holes 32A and elongated holes 32B, and the decompression chambers 150A and 150B in the upper conveyor 28 are depressurized, the workpiece W is placed on the conveying surface 30. Adsorption can be held. Further, since the honeycomb structures 154A and 154B are provided in the decompression chambers 150A and 150B, the suction flow can be rectified, the suction force can be improved, and the sound during suction can be reduced. Furthermore, since the round holes 32A and the long holes 32B having different shapes and dimensions are combined, the size change of the workpiece W can be coped with favorably.

(5) Since the tension adjusting mechanism 106 is provided, the belts 90A and 90B for transmitting the outputs of the motors 84A and 84B to the rotating brushes 50A and 50B even when the rotating brushes 50A and 50B are moved up and down. The tension can be properly maintained without sagging.
(6) A lower conveyor 34 that conveys the workpiece W in a direction opposite to the conveying direction of the upper conveyor 28 is installed at the lower stage of the upper conveyor 28, and the workpiece W that has passed through the upper conveyor 28 is transferred to the lower conveyor 34. Since the drop guide 42 for feeding is provided, even one worker can perform processing efficiently.

(7) Since the pair of rotating brushes 50A and 50B are arranged substantially in parallel and rotated in the reverse direction, a dust collection effect is obtained, and it becomes easy to collect chips and dust.
(8) Providing a rotary shaft 74 for rotating the rotary brushes 50A and 50B, pulleys 86A and 86B at the tip, and extendable covers 94A and 94B and covers 96A and 96B for covering the belts 90A and 90B. Therefore, it is possible to prevent chips and dust from being applied to the electrical system.

(9) Since the small motors 28A and 34A are provided on the upper conveyor 28 and the lower conveyor 34, the upper conveyor 28 or the lower conveyor 34 can be easily detached from the main body frame 12 as necessary. For this reason, maintenance etc. become easy.
(10) Since the casters 148 are provided, the installation location can be easily changed.
(11) Since the rotating brushes 50A and 50B can be driven independently, efficient deburring can be achieved by changing the inclination angle, roughness, height, rotational speed, etc. of the brush body 58.

(12) Since the decompression device 160 serves as a means for decompressing the inside of the upper conveyor 28 and a means for collecting chips or dust, the construction of the device can be simplified.
(13) Since the window 25 and the transparent cover 25A are provided on the side cover 24B, the state of the rotating brushes 50A and 50B can be confirmed from the outside, and the replacement time can be easily grasped.

  Next, a modification of the present embodiment will be described with reference to FIG. First, the rotating brush 220 shown in FIG. 12A is an example in which a sandpaper 226 is directly fixed to a substantially ring-shaped groove 224 formed on the surface of the roller 222 by a string 228. Further, like the rotating brush 230 shown in FIG. 12B, a plurality of continuous gripping portions 236 each having a plurality of grooves 234 formed continuously on the surface of the roller 232 are provided at appropriate intervals, and a sandpaper 238 is tied to the grooves 234 with a string 240. It may be fixed. In this way, the sandpaper 238 may be strengthened in a bundle to improve the deburring effect by centrifugal force. Further, as in the rotating brush 250 shown in FIG. 12C, a plurality of recesses 254 having a predetermined depth are formed in the roller 252 at appropriate intervals, and a plurality of grooves 256 are formed on the bottom surface of the recesses 254 so that the sand The paper 258 may be fixed to the groove 256 with a string 260. In this case, when compared with the example shown in FIG. 12B, the sandpaper 258 can be prevented from standing by the inner surface of the recess 254 by centrifugal force, and the sandpaper 258 is worn to the upper end of the recess 254. It is easy to grasp the replacement time, such as replacing it when it is done.

  Further, as in the rotating brush 270A shown in FIG. 12D, a plurality of shallow grooves 274 are formed at appropriate intervals in the vicinity of the surface of the roller 272, and two sandpapers 276 and 278 are overlapped on the groove 274 so as to form a string. It may be fixed at 280 to prevent angle change due to centrifugal force. At this time, by setting the outer sandpaper 278 to a reference length for replacing the inner sandpaper 276, it is possible to clarify the replacement time. Further, like the rotating brush 270B shown in FIG. 12E, sandpapers 276 and 282 having the same length may be stacked and fixed to further improve the deburring efficiency.

  Next, Embodiment 2 of the present invention will be described with reference to FIG. FIG. 13 is a side view showing rotating brushes of the present example and comparative example. In the first embodiment described above, as a modified example of the rotating brush, the rotating brush can be divided along a plane substantially orthogonal to the axial direction (see FIGS. 9B and 9C). Then, it has the structure which divided | segmented the rotating brush diagonally with respect to the axial direction. As shown in FIG. 13A, the rotating brush 400 of this embodiment has a configuration in which a large number of substantially ring-shaped brush bodies 430 inclined at a predetermined angle are provided on the surface of the roller. As shown in FIG. 13B, the rotary brush 400 is divided into a roller unit 402 and 404 and a pair of end units 406 and 408 by a dividing surface 410 having substantially the same inclination as the inclination of the brush body 430. It can be divided. The roller units 402 and 404 are provided with the brush body 430 to the vicinity of both ends. The roller units 402 and 404 and the end units 406 and 408 are detachable by various known mechanisms.

  The rotating brush 400 normally has a high use frequency near the center, and a worn portion 412 is formed as shown in FIG. However, in this embodiment, after the rotary brush 400 is disassembled into four parts as shown in FIG. 13 (B), the positions of the roller units 402 and 404 can be switched as shown in FIG. 13 (C). It has become. That is, the end surface 402A of the roller unit 402 and the end surface 404B of the roller unit 404 are connected, the end surface 402B of the roller unit 402 is connected to the end surface 408A of the end unit 408, and the end surface 404A of the roller unit 404 is connected to the other end. By connecting to the end surface 406 </ b> A of the end unit 406, the wear portion 412 can be moved to both ends of the rotating brush 400.

  Further, since the roller units 402 and 404 can be rotated, the uniformity of the contact surface can be maintained. Further, the roller unit end faces 402A, 402B, 404A, 404B are formed on a slope having substantially the same gradient as the brush body 430, and the brush body 430 is provided to the vicinity of the end face, whereby a gap is formed in the joint between the roller units. Does not occur. For example, in the case of a configuration in which a divided surface 426 that is substantially orthogonal to the axial direction is divided into roller units 422 and 424 as in the comparative example of the rotating brush 420 shown in FIG. 14D, these end surfaces 422B and 424A, or When the end faces 422A and 424B are connected, a gap is generated at the joint portion. In the first embodiment, as shown in FIG. 9C, the gap is prevented from being generated by increasing the inclination of the brush body, but in this embodiment, the above-described configuration is used. The surface of the workpiece W can be uniformly processed without increasing the inclination of the brush body.

  Next, Embodiment 3 of the present invention will be described with reference to FIG. In Example 1 described above, a large number of brush bodies are inclined and fixed with respect to the axial direction in a substantially ring-shaped groove or recess inclined at a predetermined angle with respect to the axial direction of the roller of the rotating brush. The present embodiment is an example in which the brush body is attached so as to be substantially orthogonal to the axial direction. FIG. 14A is a view showing a rotating brush according to the present embodiment, where FIG. 14A is a side view, and FIG. 14B is a sectional view taken along line # D- # D as viewed in the direction of the arrow. Sectional views (C) and (D) are plan views showing modifications. As shown in FIG. 14A, the rotating brush 500 of this embodiment has a plurality of substantially ring-shaped grooves 504 inclined at a predetermined angle with respect to the axial direction of the roller 502 in the axial direction at predetermined intervals. The brush body 506 is fixed to the groove 504. In the groove 504, as shown in FIG. 14B, a pair of side surfaces 504A and 504B are substantially orthogonal to the axial direction of the roller 502, and a substantially strip-shaped sandpaper is folded in two on the bottom surface 504C. Is fixed to the bottom surface 504C of the groove 504 by a string 510 or the like.

  In this embodiment, the side surfaces 504A and 504B of the groove 504 are substantially orthogonal to the axial direction of the roller 502, and the brush body 506 is also approximately orthogonal to the axial direction (in other words, the roller 502 The brush body 506 is formed so as to be in a substantially normal direction of the surface), and the groove 504 itself is formed to be inclined with respect to the axial direction of the roller 502. For this reason, as shown in FIG. 14A, the entire ring formed of the brush body 506 is inclined at a predetermined angle with respect to the axial direction, and the same effect as in the first embodiment described above can be obtained. It is done. Further, since the brush body 506 is substantially orthogonal to the roller 502 (orients in the normal direction), it is not necessary to consider the influence of centrifugal force, and the depth of the groove 504 can be reduced. Become. The examples shown in FIGS. 14A and 14B are merely examples, and the sandpaper 508 is fixed to the groove 504 in a stepped manner by appropriate means as in the rotating brush 520 shown in FIG. 14C. Alternatively, as in the rotating brush 530 shown in FIG. 14D, a substantially step-like groove 532 is formed on the roller 502, and the sandpaper 508 is fixed to each step by appropriate means. May be.

  Next, Embodiment 4 of the present invention will be described with reference to FIG. FIG. 15 is an explanatory diagram relating to the mounting angle of the rotating brush of this embodiment. The same reference numerals are used for the same or corresponding components as in the first embodiment (the same applies to the following embodiments). In the first embodiment, the rotating brushes 50A and 50B are arranged so as to be substantially orthogonal to the conveying direction of the workpiece W as shown in FIG. 15B-2. ), The rotary brush 50A is disposed obliquely with respect to the transport direction. As described in the first embodiment, the rotating brush 50A shown in FIG. 15B-2 includes a rotating brush 600 (see FIG. 15B-1) provided with a brush body 602 that is substantially orthogonal to the axial direction of the roller 56. )), The burrs formed on the side surfaces L3 and L4 of the workpiece W are easier to remove. However, since the workpiece W is fed so as to be substantially orthogonal to the roller 56, the edge of the side face L3, L4 is only half the brush rotational speed compared with the side face L1, L2, and the tip of the sandpaper 59 hits. Absent.

  Therefore, as shown in FIG. 15A, the surface corresponding to the side surfaces L3 and L4 is increased by tilting the roller 56 of the rotating brush 50A by about 10 to 20 degrees from the state shown in FIG. 15B-2. The edges are deburred well. Of course, the inclination angle of the brush body 58 with respect to the roller 56 may be increased as in the first embodiment. In this embodiment, for example, as shown in FIG. 15C, deburring is performed by rotating brushes 50A and 50B having an angle with respect to the conveyance direction of the workpiece W, and a roller 56 is further disposed in the conveyance direction. The surface treatment is performed by another rotating brush 50C that is substantially orthogonal, but this is an example, and only one rotating brush that is angled with respect to the conveying direction may be used. Alternatively, as shown in FIG. 15D, the rotary brush 50A can be rotated about one bearing as indicated by an arrow F15, and the angle of the roller 56 is adjusted according to the workpiece W. May be. Thus, by providing the roller of the rotating brush obliquely with respect to the conveying direction of the workpiece W, the effect of the processing by the rotating brush of the present invention can be further improved. Of course, in the second and third embodiments described above, similarly, the rotating brush may be installed obliquely with respect to the transport direction.

  Next, Embodiment 5 of the present invention will be described with reference to FIG. 16A and 16B are views showing Embodiment 5 of the present invention, in which FIG. 16A is a sectional view of a roller of a rotating brush cut along a plane substantially parallel to a groove, and FIG. 16B is an external perspective view showing the roller. C) is a perspective view showing the roller molding die. In the first embodiment described above, in order to transmit the rotation of the motor as the driving means to the rotating brush, the inner insert 68 is inserted into the hollow portion 66 of the roller, and the groove 66A of the hollow portion 66 and the insert 68 are The key 68A is engaged, and the rotary brush and the insert are rotated together. On the other hand, as shown in FIG. 16A, the roller 610 of this embodiment has a pair of grooves 66A and 66B formed symmetrically in the hollow portion 66, and is engaged with a pair of keys of an insertion body (not shown). It is supposed to be combined. In this embodiment, as shown in FIG. 16B, the roller 610 is formed by a combination of a set of divided bodies 610A and 610B that can be divided along the axial direction.

  The divided bodies 610A and 610 have substantially symmetrical shapes, and are formed by a pair of molds 620 and 630 as shown in FIG. One mold 620 has a configuration in which a convex curved portion 622 for forming the groove 56A is provided on a concave curved surface portion 622 for forming the outer peripheral surface of the roller 610, and the other mold 630 includes A convex portion 634 for forming the grooves 66 </ b> A to 66 </ b> B is provided at a substantially central portion of the convex curved surface portion 632 for forming the hollow portion 66. Thus, according to the present embodiment, uneven rotation can be prevented by forming the opposing grooves 66A and 66B in the hollow portion 66 of the roller 610. In addition, by making the roller 610 divided into substantially the same shape along the axial direction, an effect that it can be easily molded using a mold can be obtained.

  Next, Embodiment 6 of the present invention will be described with reference to FIGS. 17A is a plan view of the rotating brush of this embodiment, FIG. 17B is a perspective view showing the brush body, FIG. 17C is an exploded perspective view of the rotating brush, and FIG. 17D is a brush. It is explanatory drawing which shows the attachment method of a body. FIG. 18 is a diagram illustrating a modification of the present embodiment. In Examples 1 to 5 described above, by fixing a large number of brush bodies in grooves provided on the surface of the roller, a plurality of rings inclined at a predetermined angle with respect to the axial direction of the roller are formed, and the irregularities 3 Although the surface treatment of the processing object having a three-dimensional shape is performed, the present embodiment is an example in which the surface treatment in all directions is performed without forming an inclined ring by the brush body.

  As shown in FIG. 17A, the rotating brush 700 of this embodiment has a structure in which a large number of brush bodies 704 are provided on the surface of a roller 702. The brush body 704 has a narrow strip shape as shown in FIG. 17B, and sandpaper is used in this embodiment. The brush body 704 is fixed at an angle so that the length direction thereof is substantially orthogonal to the axial direction of the roller 702 and the width direction thereof is not orthogonal to the axial direction of the roller 702. ing.

  In this embodiment, the roller 702 is formed by a combination of a pair of divided bodies 702A and 702B that can be divided along the axial direction, as in the fifth embodiment. Further, the divided bodies 702A and 702B are constituted by covers 712A and 712B having a substantially arc-shaped cross section, and main bodies 710A and 710B fitted into recesses of these covers. The main bodies 710A and 710B are formed with grooves 66A and 66B for engaging a pair of keys of an insertion body (not shown). The covers 712A and 712B are provided with a number of holes 714 corresponding to the arrangement of the brush bodies 704. As shown in FIG. 17D, when one end 704B side of the brush body 704 is inserted into the hole 714 of the cover 712A and the cover 712A is put on the main body 710A, the end 704B is pressed by the main body 710A. The brush body 704 is fixed to the roller 702. The same applies to the other divided body 702B side.

  In the present embodiment, the burr in all directions to be processed can be removed by fixing the brush body 704 at an angle and rotating the rotating brush 700. For example, two rotating brushes 700 are prepared as in the first embodiment, and are driven at a rotational speed of 1200 rpm to 1500 rpm so that the rotation is reversed, and the conveyor (upper conveyor 28) is 2 m / min. It was confirmed that burrs could be removed satisfactorily by driving at about 3 m / min. Thus, according to the present embodiment, the length direction of the strip-like brush body 704 is substantially orthogonal to the axial direction of the roller 702, and the width direction of the brush 704 body is relative to the axial direction of the roller 702. Since a large number of brush bodies 704 are provided on the surface of the roller 702 so as to be non-orthogonal, burrs in all directions can be satisfactorily removed without considering the influence of centrifugal force. It should be noted that a mechanism that swings the rotating brush 700 in the axial direction may be used in accordance with the distance or angle between the brush bodies 704.

  FIG. 18 shows a modification of this embodiment. First, in the rotating brush 720 shown in FIGS. 18A to 18C, the lengthwise direction of the many strip-like brush bodies 724 provided on the surface of the roller 722 is substantially perpendicular to the axial direction of the roller 722. The width direction is substantially parallel to the axial direction of the roller 722. As shown in FIG. 18C, the roller 722 includes a substantially cylindrical cover 728 and a main body 726 that can be fitted into a hollow portion of the cover 728, and the cover 728 includes the brush 722. A number of holes 730 are provided through which the body 724 is inserted. In the illustrated example, the main body 726 is inserted into the cover 728 in a state where one brush body 724 is inserted into two holes 730 and pulled out so that the lengths of both ends 724A and 724B are equal. The brush body 724 can be fixed by pressing the bent portion 724C of the brush body 724 with the main body 726. Even in such an arrangement, it was confirmed that deburring can be satisfactorily performed under the same conditions as in the example shown in FIG.
