Description

  The present invention relates to a grindstone cleaning method and a grinder equipped with a grindstone cleaning means.

  Conventionally, in the manufacturing process using molds such as molds or sand molds in the manufacture of various products, for the purpose of adjusting the dimensions and shape of the workpieces formed using the molds or improving the surface accuracy, The grinding process is performed.

  In such a grinding process, a grinder equipped with a grindstone may be used. In this grinding machine, a disk-shaped grindstone is rotated, and a workpiece is pressed against the working surface of the rotating grindstone to perform a grinding process.

  There are two types of grinding processes: wet grinding and dry grinding. In the wet grinding process, heat generated by friction between the grinding wheel and workpiece is suppressed by applying the grinding liquid to the grinding wheel. This cooling liquid also functions as a cleaning liquid, and suppresses clogging due to cutting scraps generated by grinding on the grindstone.

  On the other hand, in the dry grinding process, since there is no means for removing deposits such as scraps attached to the grindstone, the grinding process is periodically interrupted to remove the deposits adhered to the grindstone. Specifically, compressed air was blown onto the grindstone, a brush or grindstone block was pressed against and rubbed, or a pad soaked with a solvent was pressed against.

  Alternatively, in order to remove the deposits causing clogging, a so-called “dressing” is performed in which a dedicated tool or abrasive is pressed against the surface of the grindstone, and the abrasive grains on the surface of the grindstone are scraped together with the deposits. It was.

  As one of such grinders, a grinder using a grindstone whose surface is oxidized is known. In this grinding machine, while the grindstone is protected by a natural oxide film generated on the grindstone surface, clogging is prevented by peeling off the oxide film by dressing to expose a new working surface. (For example, refer to Patent Document 1).

In addition, in such a grinding machine that forms an oxide film on the surface of the grindstone, even when the grinder is not used, the oxide film may grow on the surface of the grindstone, and an oxide film having a thickness greater than necessary may be formed. As a result, the thickened oxide film at the start of the cutting process may not be sufficiently peeled off, and the cutting process may not be performed with certainty. A removal process is performed.
JP 2002-120148 A

  However, in a grinding machine using a grindstone in which an oxide film is not formed on the surface of the grindstone, it is necessary to remove the deposits that cause clogging. Therefore, there is a problem that it is difficult to improve the production efficiency because it is difficult to reliably remove the material, or a process that lowers the work efficiency such as replacement of the grindstone is required.

  In particular, when the deposits are removed by dressing and a new working surface is exposed, the abrasive grains on the working surface are scraped off even if the abrasive grains on the grindstone working surface have not completely lost their sharpness due to the deposits. As a result, the service life of the grindstone was shortened.

  The present inventors have developed the present invention by developing the grindstone efficiently so that the deposits can be removed in a grinder that requires such deposit removal processing. .

  In the grinding stone cleaning method of the present invention, in the grinding stone cleaning method of adhering an adhesive sheet having adhesiveness to the working surface of the grinding stone, and removing the deposits attached to the working surface by peeling the adhesive sheet from the grinding stone, The pressure-sensitive adhesive sheet was pressed with a pressure roller to adhere to the working surface.

  Further, in the grinding machine provided with the cleaning means for the grinding wheel of the present invention, in the grinding machine provided with the grinding stone used for the grinding process and the cleaning means for removing the deposits attached to the working surface of the grinding stone, the cleaning means is: The pressure-sensitive adhesive sheet is adhered to the working surface so as to adhere to the pressure-sensitive adhesive sheet, the pressure-rolling roller for rolling the pressure-sensitive adhesive sheet to adhere to the working surface, and the peeling tool for peeling the pressure-sensitive adhesive sheet from the working surface.

Furthermore, the grinding machine provided with the grinding stone cleaning means of the present invention is also characterized by the following points. That is,
(1) The stripping tool is a take-up reel that winds the adhesive sheet.
(2) The working surface is a flat plate, and a support base including a rolling roller, a take-up reel, and an original fabric roll for feeding the adhesive sheet is moved along the working surface.
(3) The working surface is flat, and the pressure roller is moved along the working surface, and the take-up reel is moved along the working surface to peel off the adhesive sheet from the working surface.
(4) The moving speed of the take-up reel relative to the working surface can be adjusted.

  Further, in the grinding machine provided with the cleaning means of the grinding wheel of the present invention, in the grinding machine provided with the grinding stone used for the grinding process and the cleaning means for removing the deposits attached to the working surface of the grinding stone, the cleaning means is The pressure-sensitive adhesive sheet is superposed on the working surface and adhered, and the pressure-sensitive adhesive sheet is rolled to adhere to the working surface and the pressure-rewinding reel for winding the pressure-sensitive adhesive sheet is provided.

  In the present invention, the deposits that cause clogging of the grindstone can be removed very easily and reliably by removing the adhering sheet by adhering the pressure sensitive adhesive sheet to the working surface of the grindstone. Moreover, unlike the dressing, the working surface is not scraped off, so that the life of the grindstone can be extended and the manufacturing cost can be reduced.

  In the grinding machine equipped with the grinding stone cleaning method and the grinding stone cleaning means of the present invention, the adhesive surface having adhesiveness is adhered to the working surface of the grinding wheel, and the adhesive sheet is peeled off from the working surface to the working surface. The grindstone is removed to remove the adhered matter.

  In particular, when the pressure-sensitive adhesive sheet is adhered to the working surface, the pressure-sensitive adhesive sheet superimposed on the working surface is securely adhered by rolling with a rolling roller.

  In other words, the working surface of the grindstone has a minute but uneven shape, so that the adhesive sheet is placed on the working surface and the adhesive sheet is pressed by the pressure roller, so that the adhesive sheet is also placed on the concave portion of the working surface. The adhesive layer is brought into contact with each other so that the deposits that are likely to remain in the recesses on the working surface are reliably adhered to the adhesive sheet and can be removed.

  Moreover, when the pressure is applied by the pressure roller, a pressing force acts on the pressure-sensitive adhesive sheet in a direction perpendicular to the working surface of the grindstone. It is possible to apply a peeling force in a direction perpendicular to the working surface of the grindstone through the adhesive layer by the restoring force of the pressure sensitive adhesive sheet, and subsequently peel off the pressure sensitive adhesive sheet from the working surface of the grindstone. As a result, the deposits can be reliably peeled off and removed from the working surface.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram of a main part of a grinding machine according to a first embodiment.

  The grinding machine of the first embodiment includes a flat grindstone 11 having a peripheral surface as an action surface, and a cleaner unit 21 for removing deposits adhering to the action surface of the grindstone 11. In the present embodiment, the grindstone 11 is formed by bonding fine abrasive grains made of black silicon carbide with a thermoplastic resin, and is used for adjusting the shape of a work mainly composed of a carbon material.

  The cleaner unit 21 includes an adhesive sheet 21a that adheres to and adheres to the working surface of the grindstone 11, and a rolling roller 21b that rolls the adhesive sheet 21a to adhere to the working surface. In the present embodiment, the adhesive sheet 21a is made of cello tape (registered trademark). The pressure-sensitive adhesive sheet 21a is supplied as a raw roll 21c wound in a roll shape, and this roll body is mounted on a predetermined support shaft 21d so that the pressure-sensitive adhesive sheet 21a can be fed out.

  The adhesive sheet 21a fed out from the original roll 21c is taken up by a take-up reel 21e. That is, the take-up reel 21e is rotationally driven in conjunction with an output shaft of a drive motor (not shown), and the adhesive sheet 21a is fed out from the original roll 21c as the take-up reel 21e is driven to rotate.

  The rolling roller 21b is disposed between the original roll 21c and the take-up reel 21e, and presses the adhesive sheet 21a fed out by the take-up reel 21e against the working surface of the grindstone 11 with a predetermined pressure. The rolling roller 21b is disposed so as to be movable forward and backward with respect to the grindstone 11, and when the adhesive sheet 21a is adhered to the working surface of the grindstone 11, the rolling roller 21b is advanced toward the grindstone 11 to adhere When the sheet 21a is pressed against the working surface and the adhesive sheet 21a is not adhered to the working surface of the grindstone 11, the rolling roller 21b is moved backward to provide a predetermined gap between the grindstone 11.

  Further, the rolling roller 21b has an appropriate shape according to the shape of the working surface of the grindstone 11, and the adhesive sheet 21a is adhered to the working surface of the grindstone 11 without any gap.

  When the workpiece W1 is ground by the grinding machine configured as described above, the workpiece W1 is pressed against the working surface of the grindstone 11 while the grindstone 11 is rotated. The processing position of the workpiece W1 is a position facing the rolling roller 21b with the grinding stone 11 in between, the stress generated in the grinding stone 11 when the workpiece W1 is pressed against the grinding stone 11, and the rolling roller via the adhesive sheet 21a. The stress generated in the grindstone 11 with the pressing of the grindstone 11 by 21b is canceled out.

  The pressure-sensitive adhesive sheet 21a is firmly adhered to the working surface of the grindstone 11 by the rolling roller 21b, thereby reliably adhering the adhering material adhering to the working surface, and peeling off the pressure-sensitive adhesive sheet 21a from the working surface of the grindstone 11. At the same time, deposits are removed from the working surface.

  In particular, since the pressure-sensitive adhesive sheet 21a is pressed by the cylindrical rolling roller 21b, a pressing force acts in a direction orthogonal to the working surface of the grindstone 11, and the pressure-sensitive adhesive layer of the pressure-sensitive adhesive sheet 21a is compressed and the working surface. Deforms to match the uneven shape of At this time, the adhered matter adhering to the working surface is strongly adhered to the adhesive layer of the adhesive sheet 21a. After that, when the pressing force by the rolling roller 21b is released, the force due to the restoring force of the pressure-sensitive adhesive sheet exerts a force in the direction opposite to the previous force, that is, the deposit on the acting surface. A force to peel off from the surface acts, and this force can surely peel off the deposit from the working surface.

  Furthermore, the pressure-sensitive adhesive sheet 21a is peeled off from the working surface by being taken up by the take-up reel 21e, and the adhering matter is collected.

  Here, the adhesive sheet 21a is fed out at the same speed as the moving speed of the peripheral surface of the grindstone 11 by being pressed against the grindstone 11 by the rolling roller 21b. In the present embodiment, the rolling roller 21b is not driven, and is driven by the movement of the adhesive sheet 21a as the grindstone 11 rotates.

  The take-up reel 21e winds the adhesive sheet 21a at a speed faster than the moving speed of the adhesive sheet 21a, and applies tension to the adhesive sheet 21a. The tension applied to the pressure-sensitive adhesive sheet 21a can increase the action of peeling the pressure-sensitive adhesive sheet 21a from the working surface of the grindstone 11. Can be removed.

  In the take-up reel 21e, the radius of rotation increases in accordance with the length of the wound adhesive sheet 21a. Therefore, the rotation driving amount of the take-up reel 21e is adjusted in accordance with the take-up amount. Alternatively, a tension roller is provided between the take-up reel 21e and the rolling roller 21b, and the adhesive sheet 21a is wound around the take-up reel 21e while a predetermined tension is always applied by the tension roller. Also good.

  The removal of the adhered material by the adhesive sheet 21a is not always performed, but may be performed intermittently at a predetermined timing. When the adhered material is removed intermittently, the pressure roller 21b is controlled to advance and retract. It is possible to switch between a cleaning state by the sheet 21a and a non-cleaning state in which cleaning is not performed. Alternatively, the grinding machine may be provided with a cleaning button, and when this cleaning button is operated, the grindstone may be cleaned with the adhesive sheet 21a for a predetermined time.

  As a modification of the present embodiment, as shown in FIG. 2, when grinding a relatively large work W1 ′, the grinding process is performed by pressing the grindstone 11 ′ from above the work W1 ′. In this case, a rolling roller 21b ′ is disposed at a position facing the grindstone 11 ′ across the grindstone 11 ′, and the adhesive sheet 21a ′ is pressed against the working surface of the grindstone 11 ′.

  As shown in FIG. 2, the pressure-sensitive adhesive sheet 21a ′ may be sent out horizontally by disposing the raw roll 21c ′ and the take-up reel 21e ′ at the same height as the rolling roller 21b ′.

  The pressure-sensitive adhesive sheet 21a ′ is a pull that acts on the adhered material when peeling off by peeling off from the working surface at an angle as close to 90 ° as possible from the tangential direction of the circumferential working surface of the grindstone 11 ′. Since the peeling force can be increased, the effect of removing deposits can be increased.

  FIG. 3 is a schematic diagram of a main part of the grinding machine according to the second embodiment. Similar to the grinding machine according to the first embodiment, the grinder 12 and a cleaner that removes deposits attached to the working surface of the grindstone 12. A portion 22 is provided.

  In the grinding machine of the second embodiment, the grindstone 12 is a cup-type grindstone, and has an arcuate working surface on the bottom surface. Also in this embodiment, the grindstone 12 is formed by bonding fine abrasive grains made of black silicon carbide with a thermoplastic resin, and is used for adjusting the shape of a work mainly composed of a carbon material.

  The cleaner unit 22 includes an adhesive sheet 22a that adheres to and adheres to the working surface of the grindstone 12, and a pressure roller 22b that rolls the adhesive sheet 22a to adhere to the working surface. Also in this embodiment, the adhesive sheet 22a is made of cello tape (registered trademark). The pressure-sensitive adhesive sheet 22a is supplied as a raw roll 22c wound in a roll shape, and this roll body is mounted on a predetermined support shaft 22d so that the pressure-sensitive adhesive sheet 22a can be fed out.

  The adhesive sheet 22a fed out from the original roll 22c is taken up by a take-up reel 22e. That is, the take-up reel 22e is rotationally driven in conjunction with an output shaft of a drive motor (not shown), and the adhesive sheet 22a is fed out from the original roll 22c as the take-up reel 22e rotates.

  The rolling roller 22b is disposed between the original roll 22c and the take-up reel 22e, and presses the adhesive sheet 22a fed out by the take-up reel 22e against the working surface of the grindstone 12 with a predetermined pressure.

  In particular, in the case of the present embodiment, since the adhesive strength of the adhesive sheet 22a is high, the adhesive sheet 22a is hardly peeled off from the grindstone 12, and remains adhered to the grindstone 12 as shown in FIG.

  Then, in the cleaner unit 22 of the grinding machine of the present embodiment, after the adhesive sheet 22a is adhered to the grindstone 12 by a predetermined length, the take-up reel 22e is moved in the direction opposite to the rotation direction of the grindstone 12 by an appropriate moving arm. Winding the adhesive sheet 22a while moving it causes the adhesive sheet 22a to be strongly peeled off from the working surface of the grindstone 12, and exerts a large peeling force on the adhered material on the working surface, thereby causing the adhesive sheet to act. The deposits can be reliably removed by 22a. In addition, the adhesive sheet 22a also increases the adhesiveness of the deposit by increasing the adhesive force, and increases the force to peel the deposit from the working surface of the grindstone 12.

  In addition, when the adhesive sheet 22a is peeled off from the working surface by moving the take-up side of the adhesive sheet 22a in this way, it is limited to the case where the adhesive sheet 22a to be peeled is supported by the take-up reel 22e. For example, as shown in FIG. 5, an appropriate clamp body 22f for clamping the adhesive sheet 22a may be provided, and the clamp body 22f may be moved by an appropriate moving arm to peel off the adhesive sheet 22a.

  Alternatively, instead of peeling off the adhesive sheet 22a by moving the take-up reel 22e or the clamp body 22f, for example, as shown in FIG. 6, the movement of moving the rolling roller 22b along the working surface of the grindstone 12 The adhesive sheet 22a may be peeled off while being mounted on the table 22g and moving the moving table 22g relative to the rotating grindstone 12.

  In particular, when the rolling roller 22b is moved using the moving table 22g shown in FIG. 6, the auxiliary roller 22h is mounted on the moving table 22g in the vicinity of the pressing roller 22b, and the rolling roller 22b is wound around the rolling roller 22b. The take-up reel 22e side of the adhesive sheet 22a is wound around the auxiliary roller 22h, and the adhesive sheet 22a is peeled off at a large angle with respect to the working surface, so that a large peeling force is applied to the deposit on the working surface. May be.

  Alternatively, as shown in FIG. 7, the original fabric roll 22c and the take-up reel 22e are also mounted on the moving table 22g ′ on which the rolling roller 22b is mounted, and the cleaner 22 itself is moved along the working surface. As shown in FIG. 8, the rolling-up take-up reel 22 that winds up the adhesive sheet itself is used as a rolling-up take-up roll 22j that rolls the adhesive sheet to adhere to the working surface. You may move along.

  In particular, the take-up reel 22e, the clamp body 22f, the moving bases 22g and 22g ′, and the rolling-winding roll 22j that are moved along the working surface act on the deposit on the working surface by adjusting the moving speed with respect to the grindstone 12. The magnitude of the peeling force can be adjusted, and deposits can be reliably removed at an appropriate speed according to the degree of clogging of the grindstone 12.

  In the embodiment described above, the pressure-sensitive adhesive sheet is supplied by a raw roll, but the supply of the pressure-sensitive adhesive sheet is not limited to the raw roll, for example, as shown in FIG. In the grinding machine provided with the cleaner portion 23 for cleaning the working surface of the cup-type grindstone 13, the adhesive sheet 23a is a spiral sheet having substantially the same arc as the arc-shaped working surface of the cup-type grindstone 13. The sheets 23a may be supplied by a sheet roll 23c formed into a cylindrical shape by overlapping them. In FIG. 9, 23b is a rolling roller, and 23f is an auxiliary roller.

  In the above-described grinding wheel cleaning method, it is possible to perform the cleaning process while performing the grinding process with the grindstone, but the cleaning process may be performed separately from the grinding process.

  When the cleaning process is performed as a separate process, for example, as shown in FIG. 10, a pressure-sensitive adhesive sheet 24a having a predetermined size is placed on the entire working surface of the grindstone 14 of the cup-type grindstone. The pressure-sensitive adhesive sheet 24a may be peeled off by strongly adhering while moving the rolling roller 24b along the line.

  In this case, the grindstone 14 may be in a state in which the working surface is directed upward, and can be placed on the working surface without putting any wrinkles in the adhesive sheet 24a by facing the working surface upward. Further, even when the working surface is directed downward, the pressure-sensitive adhesive sheet 24a may be lightly stuck to the working surface, and then the pressure-sensitive adhesive sheet 24a may be strongly stuck with the rolling roller 24b.

  The rolling roller 24b is a cylindrical roller, and the pressure-sensitive adhesive sheet 24a is rolled onto the working surface while revolving the rolling roller 24b along a circular path centering on the rotation axis of the grindstone 14 by an appropriate support arm (not shown). Yes. Note that the grindstone 14 may be rotated instead of the rolling roller 24b.

  Further, the rolling roller 24b is not cylindrical, but the rolling roller 24b ′ is formed in a conical shape as shown in FIG. 11 so that there is no difference between the inner peripheral edge and the outer peripheral edge on the arcuate working surface. Alternatively, the pressure-sensitive adhesive sheet 24a may be rolled.

  In the cone-shaped rolling roller 24b ′, since the angular velocity can be the same between the inner and outer peripheral edges of the arc-shaped working surface, the adhesive sheet 24a can be adhered to the working surface without causing wrinkles. Can do.

  In the case of a cylindrical roller 24b instead of the cone roller 24b ', the surface of the adhesive sheet 24a that contacts the roller 24b is made of a material having a low frictional resistance such as Teflon (registered trademark). A coating layer is provided, a Teflon (registered trademark) sheet is interposed between the pressure roller 24b and the adhesive sheet 24a, or the surface of the pressure roller 24b is coated with Teflon (registered trademark), By rolling the rolling roller 24b with respect to the adhesive sheet 24a, the difference between the inner peripheral edge and the outer peripheral edge on the arc-shaped working surface may be eliminated, and the pressure-sensitive adhesive sheet 24a may be pressed without causing wrinkles.

  When the rolling rollers 24b and 24b 'are relatively revolved along a circular orbit centered on the rotation axis of the grindstone 14, as shown in FIG. 12, the adhesive sheet 24a' is extended in the radial direction of the grindstone 14. By providing the cut line 24c, the pressure-sensitive adhesive sheet 24a ′ can be rolled without causing wrinkles. In FIG. 12, 24 h is an opening provided in the adhesive sheet 24 a ′, and the adhesive sheet 24 a ′ is beaten against the working surface of the grindstone 14 while the opening 24 h is positioned at the central axis portion of the grindstone 14.

  In particular, when the rolling rollers 24b and 24b ′ are relatively revolved along a circular track centered on the rotation axis of the grindstone 14, the rolling rollers 24b and 24b ′ are revolved as many times as necessary. Alternatively, by rotating the grindstone 14, the adhesive sheets 24a, 24a ′ can be strongly adhered to the working surface of the grindstone 14, and the effect of removing the deposits can be improved.

  When mounting the adhesive sheet 24a on the grindstone 14, as shown in FIG. 13, the adhesive sheet 24a is previously wound around the peripheral surface of a cylindrical sticking roller 24d having a peripheral surface of a required size, The affixing roller 24d is affixed by rolling along the working surface of the grindstone 14.

  The adhering roller 24d is provided with a number of minute suction ports (not shown) on the peripheral surface, and the adhesive sheet 24a is fixed to the peripheral surface of the adhering roller 14d by sucking the adhesive sheet 24a through the suction port. In this way, by mounting the adhesive sheet 24a on the grindstone 14 using the adhering roller 24d provided with the holding means for the adhesive sheet 24a, the adhesive sheet 24a can be removed even if the working surface of the grindstone 14 faces downward. Can be attached without causing wrinkles.

  The adhering roller 24d is not only used for placing the adhesive sheet 24a on the working surface of the grindstone 14, but also after adhering by adhering the adhesive sheet 24a, the adhering roller 24d is rolled along the adhesive sheet 24a. It may function as a rolling roller.

  As another embodiment, as shown in FIG. 14, the cylindrical rolling roller 24 b ″ may perform rolling on the working surface of the adhesive sheet 24 a while moving back and forth in the radial direction of the grindstone 14. Well, in this case, by rotating the grindstone 14 at a required speed, the adhesive sheet 24a can be attached to the entire working surface of the grindstone 14. In particular, the rolling roller 24b "has a crowning shape, It can be made difficult to be affected by the rotation of the grindstone 14. The number of rolling roller 24b "is not limited to one, and a plurality of rolling rollers 24b" may be provided.

  When peeling off the adhesive sheet 24a adhered to the grindstone 14 in this way, as shown in FIG. 15, one end of the adhesive sheet 24a is clamped with the clamp body 24f, and the clamp body 24f is moved to move off. Alternatively, as shown in FIG. 16, the adhesive sheet 24a may be peeled off while being wound around the circumferential surface of the cylindrical winding roller 24e. The take-up roller 24e is provided with a large number of minute suction ports (not shown) on the peripheral surface in the same manner as the sticking roller 14d, and the adhesive sheet 24a is sucked and fixed to the peripheral surface by the suction ports so that it can be wound.

  As shown in FIG. 15, when the adhesive sheet 24a is peeled off by the clamp body 24f or the take-up roller 24e, the adhesive sheet 24a is positioned so as to be easily grasped by the clamp body 24f or the take-up roller 24e. The reference position mark (not shown) provided on the peripheral surface of the grindstone 14 is detected by the detection sensor S1, and the reference position of the grindstone 14 is aligned. The reference position mark is not only provided on the peripheral surface of the grindstone 14, but may be provided on the back surface of the grindstone 14 provided on the peripheral surface of the grindstone 14, or provided on the rotating shaft that rotates the grindstone 14. A detection sensor S1 for detecting the reference position mark may be provided as appropriate.

  Alternatively, when the cutting line 24c along the radial direction of the grindstone 14 is provided in the adhesive sheet 24a ′, as shown in FIG. 17, the knob allowance 24g is previously extended along the 24c cutting line, The gripping allowance 24g may be clamped with a clamp body or hooked on an appropriate locking piece, and the grindstone 14 may be rotated to peel off.
