Description

  The present invention relates to a rust preventive film that covers one side of a design surface of a vehicle wheel, and a decorative surface of the wheel from the design surface side, and a release paper attached to the adhesive surface of the rust preventive film. It is related with the release paper peeling apparatus of the antirust film sheet which peels off this release paper from the antirust film sheet which consists of these.

  In general, a design surface of a vehicle wheel mounted on an automobile or the like is formed with a plurality of decorative holes along the circumferential direction in order to improve design properties and improve heat dissipation of a brake. This wheel is attached to the axle of the automobile production line after the tire is assembled. The automobile produced in this way is temporarily stored and transported to the customer until it is delivered to the customer. During such storage and transportation, the automobile is exposed to rainwater, moisture-containing air, and the like, so that the brake disc viewed through the decorative hole of the wheel tends to rust. In particular, when the ship is transported by sea, such as a ferry, salt-containing air directly comes into contact with the brake disk from the decoration hole, making the brake disk more susceptible to rust.

  Since the rusted brake disc can be visually recognized from the decoration hole relatively easily without affecting the brake performance, it may impair the customer's feelings. For this reason, automobile manufacturers have recently emphasized the prevention of rusting of brake discs until they are delivered to customers. Temporarily covering the decorative holes of the wheel from the outside, during storage and transportation periods In addition, the outside air containing moisture is prevented from entering from the decoration hole. As specific means for covering the decorative hole, a rust-proof wheel cover or a water-proof rust-proof film formed in accordance with the design surface shape is used.

  Here, the rust-proof film is generally made of a flexible resinous film, and covers the decorative hole of the wheel by sticking an adhesive surface formed on one surface thereof to the design surface of the wheel. And since this rust-proof film can be manufactured comparatively cheaply and is flexible, it can be closely_contact | adhered with respect to the various uneven | corrugated shape of a design surface, and also has the advantage that it is easy to interrupt | block outside air.

  In order to protect the adhesion surface of the rust-proof film until just before being affixed to the design surface of the vehicle wheel, a release paper is affixed to the adhesion surface. For this reason, in the work site which affixes a rust prevention film to a design surface, the work which peels off this release paper is performed. Here, the rust-proof film is produced as a rust-proof film sheet cut into a predetermined circular or donut shape after a release paper is attached to the adhesive surface. Since the rust-proof film and the release paper are adhered smoothly, when the release paper is peeled off, it is difficult to peel the release paper from the rust-proof film. For this reason, in the work of peeling the release paper from the rust-proof film sheet, since the worker cannot peel off the release paper well, the rust-proof film is torn or the adhesive surfaces are adhered to each other. There are many failures and lacks certainty.

By the way, the structure which peeled off release paper from a rust prevention film sheet, for example like patent document 1, and affixed the rust prevention film on the design surface of a vehicle wheel is automated. In this configuration, the gripping protrusion is gripped and the release paper is peeled off from a rust-proof film sheet that is cut into a circular or donut-shaped outer peripheral edge. In such a configuration, by automating the work of peeling off the release paper, it is possible to reliably attach the rust-proof film to the design surface without causing the above-described problems.
Japanese Patent Laid-Open No. 2005-225082

  In the conventional configuration in which the anticorrosive film is automatically attached to the design surface of the wheel, it is necessary that the anticorrosive film sheet is provided with a gripping protrusion having a predetermined step size. That is, the shape of the rust preventive film sheet that can peel the release paper is limited. However, in the rust-proof film sheet, the size and shape of the gripping projection, the arrangement position, and the like are variously set. This is because, for example, by changing the dimensional shape of the gripping protrusion, it is possible to properly determine what corresponds to various types of vehicle wheels. For this reason, what can peel the release paper reliably from the antirust film sheet which has the grip protrusion part of various dimensions shape is calculated | required.

  Also, as a rust-proof film sheet, in the cutting work, cutting into a relatively simple circle or donut shape is easier to work and producing than cutting into a shape having this gripping protrusion. There is an advantage of superiority. Thus, when using the rust prevention film sheet | seat which does not have a grip part, the operator will perform the operation | work which peels off a release paper. However, the release work of the release paper by the operator has problems such as many failures as described above, and a relatively long time for the peeling work.

  In addition, as for vehicle wheels, various designs having various design surfaces have been proposed one after another. For this reason, the decorative holes are set in various shapes and sizes for each wheel type. Even for such a design surface shape, a relatively simple circular or donut shape is the most versatile as the anticorrosive film sheet. However, in the future, various shapes of rust-proof film sheets will be used depending on the shape of the design surface and decoration holes, such as changing the shape of the outer peripheral edge while making the basic shape circular or donut shape I can guess that too. Thus, there is a need to ensure that the release paper can be peeled off reliably and efficiently, regardless of the size and shape of the gripping protrusions, and even in various forms of rust-proof film sheets. Yes.

  This invention provides the release paper peeling apparatus of the antirust film sheet which can peel the release paper reliably and efficiently from the antirust film sheet of various shapes.

  The present invention has an adhesive surface for joining one side to the design surface of a vehicle wheel, a rust preventive film for covering the decorative hole of the wheel from the design surface side, and an adhesive surface of the rust preventive film. A release paper peeling device for peeling off a release paper from a release film formed from a release paper that is separated and peeled off on both sides of a separation line formed so as to cross in a direction. The film sheet is slidably joined to the opposite surface of the adhesive surface of the anticorrosive film and held in a flat shape, and is placed at a predetermined peeling operation position, and the sheet positioning means is located at the peeling operation position. The support roll that holds the release paper of the rust film sheet, the suction part held on the roll surface of the support roll, and the side of the release line of the release paper of the rust prevention film sheet at the peeling operation position. Side A release paper peeling device for a rust-proof film sheet, comprising: a roll driving means for moving the suction part from the operation starting position for sucking the suction part to the release paper in a direction opposite to the separation line. It is.

  Here, the rust-proof film sheet has a release line formed with a separation line substantially along the radial direction. In addition, since the release paper on which the separation line is formed in this way can be separated and peeled off when the operator peels off manually, there is also an effect of reducing failure due to the above-mentioned manual work. Yes, this effect is negligible. Further, even if the release paper is divided and peeled off, there still remains a problem that a worker spends a relatively large amount of work time on the work to be peeled off.

  Such a configuration is an apparatus that can peel off the release paper from a rust-proof film sheet in which a release line is formed on the release paper. That is, the anticorrosive film sheet is positioned at the peeling operation position by the sheet positioning means, and the supporting roll is adsorbed to the release paper by the side of the separation line at the operation start position. Then, by moving the support roll while rotating it in the direction opposite to the separation line from the operation start position by the roll driving means, the region adsorbed by the adsorbing part is peeled off from the rust preventive film, and the support roll It can be wound up and peeled off from the adhesive surface of the anticorrosive film.

  Here, the support roll that moves together with the rotation by the roll driving means takes up the release paper by rotating the suction portion while pressing the release paper on the roll surface. And the antirust film sheet | seat is hold | maintained planarly by the sheet | seat positioning means in the peeling operation position. Thus, in the process of peeling off the release paper, the flexible rust preventive film is not torn and the adhesive surfaces are not stuck to each other.

  Thus, according to the release paper peeling apparatus of this invention, a release paper can be peeled off reliably, without producing a failure, such as a rust-proof film being torn or the adhesion surfaces adhering. Therefore, after peeling off the release paper, this rust preventive film can be properly attached to the design surface of the vehicle wheel. In addition, since the release paper peeling device is configured to peel off the release paper by moving the support roll while rotating, as described above, the work required for the work for the operator to peel off the release paper. Compared to the time, the time taken to peel off the release paper can also be shortened.

  For example, when the rust-proof film sheet has a single release line formed on the release paper, the release-paper release device of the present invention is the rust-proof film sheet in the release operation position. It is assumed that two support rolls adsorbing on both sides of the separation line are provided and both are rotated and moved substantially simultaneously. Thereby, each area | region divided into two by one cutting line of a release paper can be peeled off substantially simultaneously. In this way, it is possible to further reduce the time taken to peel the release paper from the rust-proof film sheet.

  Furthermore, since the release paper peeling device of the present invention performs the operation of peeling the release paper by the rotation and movement of the support roll as described above, the release paper is removed from the rust-proof film sheets of various shapes. Can be peeled off. That is, the rust-proof film sheet does not require requirements such as the presence or absence of a gripping protrusion, the size and shape of the gripping protrusion, and the location of the gripping protrusion. Moreover, even when using the antirust film sheet of various shapes according to the design surface shape of the wheel for vehicles, the release paper of this antirust film sheet can be peeled off reliably and efficiently. Therefore, the release paper peeling apparatus of this invention has the outstanding convenience that it can respond to the antirust film sheet of various shapes.

  In addition, since the sheet positioning means is joined to the opposite surface of the adhesive surface of the anticorrosive film so as to be able to contact and separate, after removing the release paper, the antirust film is removed, and the design of the vehicle wheel It can be pasted on the surface. In addition, it is also possible to transfer the rust-proof film currently hold | maintained planarly by this sheet | seat positioning means to the design surface of a vehicle wheel as it is, and to affix the said rust-proof film on a design surface. Thereby, the sticking operation | work of a rust prevention film can also be performed rapidly and appropriately.

  Furthermore, if the rust preventive film is removed from the sheet positioning means as described above, the next rust preventive film sheet can be joined again and placed at the peeling operation position. That is, the operation of joining the anticorrosion film sheet, the operation of disposing the anticorrosion film sheet, and the operation of removing the anticorrosion film (attaching to the design surface of the vehicle wheel) are sequentially repeated. This makes it possible to stably supply a rust preventive film to be applied to the design surface of the vehicle wheel. Therefore, by installing this device adjacent to a conveyor or the like that sequentially conveys the vehicle wheel, High stability and efficiency can be achieved as a line process for attaching a rust film to a vehicle wheel.

  In this configuration, as the sheet positioning means, the anti-corrosion film sheet is automatically transferred from a predetermined standby location to the peeling operation position of the apparatus, and the peeling operation position from the standby location. It is possible to adopt any configuration in which the worker performs the transfer work to the operator. Further, the roll driving means may be configured such that the support roll is mechanically rotated and moved, or the rotation and movement of the support roll are controlled.

  In the rust-proof film sheet release paper peeling device described above, the roll driving means, along the rust-proof film sheet in which the support roll is placed at the peeling operation position, and the release line of the release paper of the rust-proof film sheet, A guide mechanism that can move in the orthogonal direction and a support roll that can swing along the moving direction of the support roll that follows the guide mechanism. The support roll can move along the anticorrosive film sheet along with this swing. As described above, the swing arm connected to the rotating shaft of the support roll, the arm swing means for swinging the swing arm, the rack gear disposed along the moving direction of the support roll, and the rotation of the support roll A configuration is proposed that includes a pinion gear coupled to a shaft and meshing with the rack gear.

  In this configuration, the support roll moves according to the guide mechanism by swinging the swing arm by the arm swinging means, and the support roll is rotated by the rack gear and the pinion gear along with this movement. It is what I did. In this case, the rotation and movement of the support roll are mechanically linked. By this roll driving means, the support roll can be moved while being rotated so that the release portion is peeled off while being wound up from the operation start position where the suction portion is attracted to the release paper. Thus, it is possible to properly exhibit the effect of reliably and efficiently peeling the release paper of the present invention described above.

  Further, since this roll driving means can rotate and move the support roll for peeling off the release paper by swinging the swing arm and operating the rack and pinion gear, There is an advantage that an apparatus for controlling the rotation and movement is not required, and the power required for the control process is not required.

  The arm swinging means may be a mechanical structure that is swung by an operator's artificial force, or a structure that is swung by a motor, a pressure cylinder, or the like. Here, even in a configuration that is swung by a motor, a pressure cylinder, or the like, the power required for this can be handled with a relatively small amount, so that the overall configuration requires only a relatively small amount of drive power. Has excellent advantages.

  In the rust preventive film sheet release paper peeling device described above, two release lines parallel to each other are formed on the release sheet of the rust preventive film sheet, and the separation lines can be divided and peeled off respectively. The two small divided regions are formed, and the release member of the anticorrosive film sheet in the peeling operation position is separated from the suction member adsorbed on the inner end of the divided small region, and the peeling member The structure provided with the adsorption | suction member inclination means to incline so that it may space apart from a rust prevention film sheet from the adsorption | suction position adsorbed | sucked to the release paper of the rust prevention film sheet which exists in an outer side along a separation line is proposed.

  In such a configuration, the release paper is separated from the anticorrosive film sheet that can be peeled off by dividing the release paper into four regions of an outer region of each of the two separation lines and a small divided region between the separation lines. The pattern paper is peeled off. That is, the rust preventive film sheet is arranged at the release operation position, the adsorption member is adsorbed to the divided small area of the release paper of the rust preventive film sheet, and the adsorbing member is tilted by the adsorbing member tilting means, thereby being divided. Make sure to peel off the small area from the rust-proof film. Here, in the rust-proof film sheet that can be separated by separating the release paper in this way, when the operator works to peel off the release paper, by peeling the two divided small areas first, Thereafter, a relatively large area divided by the separation line is easily peeled off. And even if it exists in the release paper provided with such a division | segmentation small area, according to this structure, with the operation | movement which peels the outer side area of a separation line by rotation and movement of the support roll mentioned above, a division | segmentation small area | region is also made. Stripping operation can be performed. In addition, as compared with the case where the operator peels off each area of the release paper in sequence, the work time for peeling off the release paper can be shortened by this configuration. Therefore, the release paper can be reliably and efficiently peeled off from the rust-proof film sheet.

  In such a rust-proof film sheet release paper peeling device, the suction member tilting means holds the suction member, and the suction member is divided into small areas of the release paper of the rust-proof film sheet in the peeling operation position. A tilting arm supported to be tiltable so as to be separated from the rust preventive film sheet from the suction position adsorbed to the outside, along the separation line, and supported so as to be swingable along the tilting direction of the tilting arm, A configuration is proposed that includes a swinging arm in which the tilting arm is rotatably connected and an arm swinging unit that swings the swinging arm.

  In such a configuration, the tilting arm is tilted by swinging the swinging arm by the arm swinging means, and this tilting causes the rust-proof film sheet at the peeling operation position to be divided into small divided areas of the release paper. The adsorbing part that is adsorbed is separated from the rust-proof film sheet, so that the divided small areas can be peeled off from the rust-proof film. Since the present configuration mechanically tilts the suction portion in the same manner as the roll driving means described above, no device for controlling this tilt is required, and no power is required. Further, since this arm swinging means can be driven with a relatively small electric power, such as a motor or a pressure cylinder, the operation of this configuration generally requires a small amount of driving power.

  Further, in this configuration, by using the swing arm of the roll driving means and the arm swing means described above, the rotation and movement of the support roll and the tilt of the tilt arm are executed in synchronization. Is possible. That is, by actuating the arm swinging means, the operation of peeling off the outer region of the separation line and the operation of peeling off the divided small region can be performed almost synchronously. Thereby, in the operation | work which peels off this release paper from the antirust film sheet provided with the release paper which can be divided into four and can be peeled, the time required for this operation can be further shortened.

  In the release paper peeling device for the anticorrosive film sheet described above, the sheet positioning means is disposed around the positioning protrusion and the positioning protrusion that can be inserted into the hub hole of the wheel. A sheet holder having an adhesive portion for releasably joining the sheet holder, and a positioning protrusion of the sheet holder can be inserted, and the sheet holder is held by the sheet holder by inserting the positioning protrusion of the sheet holder. A configuration comprising a placement reference hole provided so as to position the rust preventive film sheet at the peeling operation position is proposed.

  In such a configuration, since the sheet holder joins the rust-proof film sheet by the adhesive portion disposed around the positioning protrusion, the rust-proof film sheet is held in a flat shape. It is easy. And by moving the sheet holder holding the rust-proof film sheet in this way so that the positioning protrusion is inserted into the placement reference hole, the rust-proof film sheet can be accurately placed at the peeling operation position. It can be done. That is, the operator can perform the operation of peeling the release paper as described above by holding the rust-proof film sheet using the sheet holder and placing it at the peeling operation position. This configuration requires the operator to operate the sheet holder, but since the operator does not take off the release paper as in the prior art, the total work of removing the release paper is not necessary. Time can be shortened. As described above, this configuration requires the operator to perform the work of placing the anticorrosive film sheet at the peeling operation position using the sheet holder, and thus is simplified as a release paper peeling device as a whole. Thus, the device itself can be made compact. Furthermore, there is also an excellent advantage that an operator can quickly respond to a malfunction such as a failure of the apparatus.

  Here, an adhesive tape, a suction disk, or the like can be used as the adhesive portion of the sheet holder.

  As described above, the release paper peeling device for the anticorrosive film sheet of the present invention forms the release paper by dividing the release paper on both sides of the separation line and separating the release paper into a planar shape by the sheet positioning means. Hold and place in the peeling operation position, the support roll, from the operation start position adsorbed on the side of the release line of the release sheet of the rust-proof film sheet in the peeling operation position, by the roll drive means, Since it is moved while rotating in the opposite direction to the separation line, the release paper on which the separation line is formed can be reliably and efficiently produced without causing a failure such as tearing of the rust prevention film. It can be peeled off. And the antirust film stuck on the design surface of the wheel for vehicles can be supplied stably. Such release paper peeling operation can be performed on rust-proof film sheets of various shapes regardless of the size and shape of the gripping protrusions, so this release paper peeling device has excellent convenience. It is. Furthermore, by installing the rust-proof film in the line process for attaching the rust-proof film to the vehicle wheel, the rust-proof film can be stably supplied, and the efficiency of the line process is increased.

  The roll driving means swings the swing arm by the arm swinging means, so that the support roll follows the guide mechanism along the anticorrosive film sheet disposed at the peeling operation position and in a direction orthogonal to the separation line. The support roll is rotated by the rack gear and the pinion gear along with this movement, so the support roll is rotated in the direction opposite to the release line of the release paper from the operation start position. By moving while moving, the release roll can be peeled off while being taken up by the support roll, and the above-described operational effects of the present invention can be exhibited appropriately. In addition, since this roll driving means can release the release paper by its mechanical operation, relatively little power is required, and the work of attaching the rust preventive film to the design surface of the vehicle wheel as a whole. The cost required for this can be suppressed.

  Further, the release paper is provided with a rust-proof film sheet having two separation lines parallel to each other and two divided small regions formed between the separation lines at the release operation position. The adsorption member is adsorbed to the inner end of the divided small area, and the adsorption member is tilted by the adsorption member tilting means so as to be separated from the rust preventive film sheet outward along the separation line. Therefore, this divided small region can be reliably peeled off from the rust-proof film sheet. And by the operation | movement which peels off the outer area | region of a separation line with the support roll mentioned above, and the operation | movement which peels off this division | segmentation small area | region, even if it exists in the said rust prevention film sheet, the release paper is peeled off reliably and efficiently. Can be. And the antirust film stuck on the design surface of the wheel for vehicles can be supplied stably.

  The suction member tilting means swings the swinging arm by the arm swinging means, so that the tilting arm provided with the suction member can be divided into small areas of the release sheet of the rust-proof film sheet at the peeling operation position. Since it is tilted so as to be separated from the rust preventive film sheet from the adsorbed adsorbing position toward the outside along the separation line, it is possible to properly exert the effect of peeling off the divided small regions described above. . If the arm swinging means and the swing arm are the same as the above-described roll driving means, the operation of winding the release paper by the support roll and the tilting of the tilting arm can be executed synchronously. The time required for the operation of peeling off the release paper is shortened, and the efficiency can be further increased. Furthermore, if the arm swinging means and the swing arm are the same as the roll driving means, the release paper peeling device can be made relatively compact, and the installation location can be easily set.

  On the other hand, the above-described sheet positioning means includes a positioning protrusion that can be inserted into the hub hole of the wheel, and an adhesive portion that is disposed around the positioning protrusion and is detachably bonded to the opposite surface of the rust preventive film. When it is provided with a sheet holder to be equipped and an arrangement reference hole for positioning the anticorrosive film sheet held by the sheet holder at the peeling operation position by inserting the positioning protrusion of the sheet holder Then, by inserting the positioning protrusion of the sheet holder holding the rust-proof film sheet into the placement reference hole, the rust-proof film sheet can be easily and accurately placed at the peeling operation position. . Even when the operator works using this sheet holder, the effect of peeling the release paper reliably and efficiently can be properly exhibited as described above.

An embodiment of the present invention will be described with reference to the accompanying drawings.
In this embodiment, as shown in FIGS. 1 and 2, the rust-proof film sheet 80 includes a rust-proof film 81 provided on one side with an adhesive surface 81a that is bonded to the design surface of the vehicle wheel, and the adhesive surface 81a. And a release paper 83 bonded to the substrate, and has a substantially donut shape. When this rust-proof film 81 is affixed to the design surface of the vehicle wheel, it has a dimensional shape that covers all the decorative holes and does not cover the bolt holes. This rust preventive film 81 is made of a water-impervious resin thin film having an adhesive surface 81a formed on one side, and after applying a predetermined adhesive on one side of the resin thin film to form the adhesive surface 81a, A release paper 83 is affixed to the entire bonding surface 81a and cut into a predetermined donut shape to produce a rust-proof film sheet 80 to which the release paper 83 is bonded. The material of the rust preventive film 81 and the release paper 83 can be the same as that of the conventional product, and the cutting method and the method of forming the separation line 84 described later can be easily manufactured by a known technique.

  In the anticorrosive film sheet 80, two release lines 84, 84 are formed on the release paper 83 so as to be substantially parallel to each other so as to cross along the radial direction. These two separation lines 84, 84 cross the release paper 83 also across the donut-shaped internal circular airspace. And by these two cut-off lines 84 and 84, two fan-shaped division | segmentation large area | regions 85 and 85 which become the outer side of each cut-off line 84 and 84, and the division | segmentation small area | region 86 between these cut-off lines 84 and 84, Two 86 are formed. That is, the release paper 83 can be divided into a total of four divided large areas 85 and 85 and two divided small areas 86 and 86, and can be peeled off from the rust-proof film sheet 80. Yes.

  In the present embodiment, the rust-proof film sheet 80 is configured not to have a grip protrusion (not shown) protruding outward at the outer peripheral edge thereof. Thus, the antirust film sheet 80 of a structure which does not have a grip protrusion can be obtained by joining a release paper to the antirust film and cutting it into a donut shape, and has an advantage of high productivity.

  The release paper peeling apparatus 1 for a rust-proof film sheet of this example will be described in order below with reference to FIGS. The release paper peeling apparatus 1 includes a sheet holder 2 (see FIGS. 4 and 5) that holds the anticorrosive film sheet 80 in a flat shape, and a release paper from the antirust film sheet 80 held by the sheet holder 2. The apparatus main body 11 (refer FIGS. 3-5) which peels 83 is provided. Here, the sheet holder 2 can be attached to and detached from the apparatus main body 11, and the rust preventive film sheet 80 is positioned at the peeling operation position O set in the apparatus main body 11. 3 to 5, in order to clarify the structure of the release paper peeling device 1, some components are appropriately omitted for each drawing.

  As shown in FIG. 6, the sheet holder 2 includes a base 3 that radially connects the inner and outer rings in a radial direction, and an inverted U-shaped grip 4 provided on the upper side of the base 3. . Further, a positioning protrusion 5 is provided on the lower side of the base 3 of the sheet holder 2 so as to protrude downward substantially at the center thereof, and a plurality of adhesive portions 6 are formed substantially radially around the positioning protrusion 5. It is arranged. Here, the positioning protrusion 5 has a dimensional shape that can be inserted into the hub hole of the vehicle wheel. Each bonding portion 6 includes a buffer material 6b provided so as to protrude downward from the base 3, and an adhesive tape 6a held on the lower surface of the buffer material 6b. The adhesive tape 6a is held by the cushioning material 6b so that the adhesive surface faces downward. And this adhesion part 6 peels off the release paper 83 so that it may mention later by setting suitably the arrangement position and number of arrangement in base 3, and the adhesive force and adhesion area of adhesive tape 6a. In addition, the rust preventive film 81 can be held in a bonded state, and the rust preventive film 81 is adjusted so that it can be separated from the rust preventive film 81 when the rust preventive film 81 is attached to the wheel design surface.

  The sheet holder 2 presses the adhesive portion 6 of the base 3 against the anticorrosive film 81 of the anticorrosive film sheet 80 against the opposite surface 81b of the adhesive surface 81a, thereby making the anticorrosive film sheet 80 planar. Can be held in. And after peeling off the release paper 83 from the antirust film sheet 80, the positioning protrusion 5 of this sheet holder 2 is inserted into the hub hole of the vehicle wheel, and the antirust film 81 is designed for the vehicle wheel. By pressing against the surface, the adhesive surface 81a of the anticorrosive film 81 is joined to the design surface. Thereafter, by separating the sheet holder 2 from the wheel, the adhesive portion 6 is separated from the rust preventive film 81, and the rust preventive film 81 is appropriately attached to the design surface. In addition, since this adhesion part 6 is comprised from the buffer material 6b and the adhesive tape 6a as above-mentioned (illustration omitted), by pressing the sheet | seat holder 2 against the antirust film sheet 80, this The antirust film sheet 80 is easily held flat. Similarly, by pressing the sheet holder 2 against the design surface of the vehicle wheel, the rust preventive film 81 can be properly attached to the design surface having an uneven shape.

  As described above, the sheet holder 2 holds the rust-proof film sheet 80 (rust-proof film 81) in a flat shape or has a rust-proof film by the buffering action of the buffer material 6b of the bonding portion 6 disposed substantially radially. 81 can be appropriately affixed to the design surface of the vehicle wheel so that the decorative hole can be covered. Furthermore, by inserting the positioning protrusion 5 into the hub hole of the wheel, the rust preventive film 81 can be attached to the design surface so as to cover all the decorative holes.

  On the other hand, the apparatus main body 11 of the release paper peeling apparatus 1 includes a cylindrical holder arrangement portion 13 that opens upward at a substantially central portion in the horizontal direction as shown in FIGS. An arrangement reference hole 12 is formed in the holder arrangement portion 13 along the vertical direction, and the positioning protrusion 5 of the sheet holder 2 described above is inserted into the arrangement reference hole 12 from above ( 10 and FIG. 11), the rust-proof film sheet 80 held in a flat shape by the adhesive portion 6 of the sheet holder 2 is positioned. With the holder placement portion 13 and the placement reference hole 12, the rust preventive film sheet 80 held by the sheet holder 2 can be placed at the peeling operation position O set in the apparatus main body 11. Here, at the peeling operation position O, the rust preventive film sheet 80 is held substantially along the horizontal direction. Further, at the peeling operation position O, the rust-proof film is arranged such that the diameter between the two separation lines 84 and 84 of the release paper 83 of the rust-proof film sheet 80 follows the arrangement reference line L defined in the horizontal direction. A sheet 80 is disposed (see FIG. 8). That is, at the peeling operation position O where the rust preventive film sheet 80 is disposed, the circumferential position of the rust preventive film sheet 80 is also determined.

  As shown in FIGS. 3 to 5, the apparatus main body 11 is provided with guide rails 14 and 14 that are parallel to each other along the direction perpendicular to the arrangement reference line L described above in the horizontal direction. The distance between the two guide rails 14 and 14 is longer than the outer diameter of the rust preventive film sheet 80. Further, the length of the guide rails 14 and 14 is such that both ends thereof are outside the outer diameter of the anticorrosive film sheet 80 when the anticorrosive film sheet 80 is disposed at the peeling operation position O. It is set. The guide rails 14 and 14 are disposed below the peeling operation position O.

  Each of the guide rails 14 and 14 is provided with a slider 15 that can move according to the guide rail 14, and each slider 15 and 15 is provided with a roll bearing (not shown) (see FIG. 7). A roll rotation shaft 41a (41b) is supported on each roll bearing so as to be free to rotate, and the roll rotation shaft 41a (41b) is parallel to the arrangement reference line L described above. That is, the roll rotation shaft 41a (41b) can be moved by the sliders 15 and 15 according to the guide rails 14 and 14 (see FIGS. 7 and 9A). Two sets of the sliders 15 and 15 and the roll rotation shaft 41a (41b) are installed on the guide rails 14 and 14, respectively.

  Two substantially semicircular support rolls 40a and 40a are fixed to the above-described roll rotation shaft 41a, and the support rolls 40a and 40a also rotate as the roll rotation shaft 41a rotates. Here, the support rolls 40 a and 40 a are set so that the roll length is slightly longer than the sheet width (the distance between the inner and outer circumferences) along the radial direction of the rust-proof film sheet 80. And these two support rolls 40a and 40a can respectively press the release paper 83 upward on the both sides along the arrangement | positioning reference line L of the rust prevention film sheet 80 arrange | positioned in the peeling operation position O, respectively. It is provided so that it can. The pressing force of the release paper 83 by the support rolls 40a and 40a is such that when the support rolls 40a and 40a wind up the release paper 83 as described later, the release paper 83 is wrinkled or displaced. It only needs to be strong enough to prevent it from happening.

  On the roll surface of the support rolls 40a and 40a, three suction pads 42 are arranged in parallel at substantially constant intervals along the roll axis direction at the circumferential end of the support roll 40a. 42 is connected to the tip of each vacuum nozzle 43 joined to the roll rotation shaft 41a (see FIG. 12). The vacuum nozzle 43 is connected to a suction device (not shown), and the suction pad 42 is attracted to the release paper 83 when the suction device performs a suction operation.

  Similarly to the roll rotation shaft 41a, the other roll rotation shaft 41b is provided with substantially semicircular support rolls 40b and 40b, and the support rolls 40b and 40b are used to perform a peeling operation. The release paper 83 of the rust prevention film sheet 80 at the position O is pressed upward. Further, three suction pads 42 are also arranged on the support rolls 40 b and 40 b on the roll surface, and each suction pad 42 is provided at the tip of the vacuum nozzle 43.

  As shown in FIGS. 8 and 12, the support rolls 40a and 40b of the roll rotation shafts 41a and 41b are arranged so that both the separation lines 84 and 84 are formed when the rust preventive film sheet 80 is positioned at the peeling operation position O. In the divided large areas 85 and 85 on the outer side, the suction pads 42 are arranged beside the separation lines 84 and 84 so that they can be sucked to the release paper 83, respectively. The positions of the support rolls 40a and 41b are the operation start positions Xa and Xb according to the present invention. Further, at the operation start positions Xa and Xb, the respective roll rotation shafts 41a and 41b are configured such that the respective support rolls 40a and 40b are convex in the direction opposite to the arrangement reference line L. That is, at the operation start positions Xa and Xb, the support rolls 40a and 40a and the support rolls 40b and 40b are opposite to each other with respect to the arrangement reference line L (see FIGS. 10, 11, and 12). .

  Here, the support rolls 40 a and 40 b are set so that the substantially semicircular arc length is longer than the outer diameter of the antirust film sheet 80. Thereby, when the support rolls 40a and 40b move while rotating as will be described later, the support rolls 40a and 40b can press the release paper 83 upward to the outer peripheral edge.

  The guide rails 14 and 14 and the sliders 15 and 15 described above constitute a guide mechanism according to the present invention. Moreover, the roll rotating shaft 41a, 41b mentioned above is a rotating shaft of the support roll concerning this invention. Further, the suction pad 42 described above is a suction portion according to the present invention.

  Further, rack gears 20 and 20 are arranged on both outer sides of the guide rails 14 and 14 in parallel with the guide rails 14 and 14 as shown in FIGS. And the pinion gears 21 and 21 which mesh with the rack gears 20 and 20 respectively are fixed to both ends of the roll rotating shafts 41a and 41b. As a result, when the roll rotation shafts 41a and 41b are moved according to the guide rails 14 and 14, the roll rotation shaft 41a is moved by the rack gear 20 and the pinion gear 21 as shown in FIG. 7, FIG. 10, FIG. , 41b are rotated. And with this roll rotating shaft 41a, 41b, support roll 40a, 40b also moves, rotating. Here, when the support rolls 40a and 40b at the operation start positions Xa and Xb described above are started to move in directions opposite to the arrangement reference line L, the suction rolls 42 of the support rolls 40a and 40b are moved in the moving direction. Start rotating in the opposite direction. That is, the support rolls 40a and 40b move while rotating along the lower surface of the release paper 83, and press the release paper 83 upward while rotating.

  Further, as shown in FIGS. 4 and 7, substantially U-shaped arm bearings 23, 23 are provided on the sliders 15, 15 that support one of the roll rotation shafts 41 a. The swing arms 24a and 24b supported so as to be swingable along the moving direction of the sliders 15 and 15 are supported so that the upper end portions of the arms can swing and move vertically. The swing arm 24a is pivotally supported by the support shaft Ma at a lower portion thereof, and is connected to the cylinder 27 at the lower end portion of the arm. The cylinder 27 is operated by gas pressure, and reciprocates in a direction substantially parallel to the guide rail 14. Therefore, by reciprocating the cylinder 27, the swing arms 24a, 24b swing, and the sliders 15, 15 move according to the guide rails 14, 14.

  That is, when one of the support rolls 40a and 40a is at the operation start position Xa, when the cylinder 27 is moved forward, the swing arms 24a and 24a swing, and the sliders 15 and 15 are moved along with the swing. The guide rails 14 and 14 move in the direction opposite to the arrangement reference line L. Thereby, the support rolls 40a and 40a move in the direction opposite to the arrangement reference line L from the operation start position Xa and rotate (see FIG. 12).

  Furthermore, as shown in FIGS. 4 and 7, the sliders 15, 15 that support the other roll rotation shaft 41 b are also provided with substantially U-shaped arm bearings 23, 23. The arm bearings 23 and 23 have swing arms 24b and 24b that are pivotally supported so as to swing along the moving direction of the sliders 15 and 15. So that it is supported. The swing arms 24b, 24b are pivotally supported by the support shaft Mb at the lower end portions thereof. Further, the swing arms 24b and 24b are connected to the swing arms 24a and 24a swinging the one roll rotation shaft 41a described above by interlocking arms 26 and 26, respectively. The interlocking arms 26 and 26 are connected to both the swinging arms 24a and 24a and the swinging arms 24b and 24b so as to be freely rotatable. Here, the swing arms 24a and 24b are connected by the interlocking arm 26 so that the support rolls 40a and 40b of the ROHM rotation shafts 41a and 41b are at the operation start positions Xa and Xb, respectively. . As described above, when the cylinder 27 is moved forward, the swinging arms 24b and 24b are also swung by the interlocking arms 26 and 26 as the swinging arms 24a and 24a swing as shown in FIG. The support rolls 40b and 40b are moved from the operation start positions Xa and Xb in the direction opposite to the arrangement reference line L, and rotated. Here, the support rolls 40a and 40b of the roll rotation shafts 41a and 41b move from the operation start positions Xa and Xb at the same speed and rotate so that the swing arms 24a and 24b and the interlocking arm 26 rotate. Is installed. Accordingly, the support rolls 40a and 40b of the roll rotation shafts 41a and 41b are interlocked so as to move and rotate in a so-called mirror-symmetric manner with respect to the arrangement reference line L.

  On the other hand, as shown in FIGS. 4 and 9, the swing arms 24a and 24a described above are substantially the same as the arm axis direction from the side edge on the arrangement reference line L side of the swing supported portion. Oscillating protrusions 30 and 30 are formed in the orthogonal direction. An operating rod 31 is pivotally supported at the lower end of the rod by the swinging protrusion 30, and a substantially square-shaped tilting member 32 is joined to the upper end of the operating rod 31. The tilting member 32 is pivotally supported by the support shaft N so as to be tiltable at both outer positions of the rust preventive film sheet 80 at the peeling operation position O substantially along the arrangement reference line L. . The tilting member 32 is joined to the operating rod 31 at the outer end portion of the bent portion, and a vacuum nozzle 34 provided with a suction pad 33 at the upper end is disposed via an attachment seat 35 at the inner end portion. Has been. When the cylinder 27 is reciprocated as described above, the swinging protrusions 30 and 30 of the swinging arms 24a and 24a swing vertically as shown in FIG. The members 32 and 32 are tilted in the substantially vertical direction, and the suction pads 33 and 33 are similarly tilted in the substantially vertical direction.

  Here, when the above-described support rolls 40a and 40b are at the operation start positions Xa and Xb, the suction pads 33 and 33 are separated from the anticorrosive film sheet 80 at the peeling operation position O as shown in FIG. The swing protrusion 30, the operating rod 31, and the tilting member 32 described above are positioned so as to be attracted to the inner portion of each of the divided small regions 86, 86 of the pattern paper 83 (hereinafter referred to as a suction position; see FIG. 13A). The mounting seat 35 and the vacuum nozzle 34 are adjusted. When the suction pads 33 and 33 are in the suction position as described above, when the cylinder 27 is moved forward, the tilting rods 31 and 31 are moved upward, and the tilting members 32 and 32 are tilted downward. As a result, the suction pads 33 and 33 are inclined downward from the suction position (see FIG. 13). Here, the inner portion of the divided small region 86 to which the suction pad 33 is sucked is a portion that is on the side of the inner peripheral edge of the donut shape between the two separation lines 84 and 84.

  The above-described vacuum nozzle 34 is connected to a suction device (not shown), and the suction pad 33 is sucked to the release paper 83 when the suction device performs a suction operation. In this embodiment, the vacuum nozzle 34 and the vacuum nozzle 43 of the support rolls 40a and 40b described above are connected to the same suction device.

  The suction pad 33 and the vacuum nozzle 34 described above constitute a suction member according to the present invention. The actuating rod 31, the tilting member 32, and the mounting seat 35 constitute a tilting arm according to the present invention.

  The cylinder 27 described above moves forward by injecting a predetermined amount of a predetermined gas into the cylinder 27, and returns to operation by discharging the injected gas (see FIG. 7). A forward switch (not shown) for executing the gas injection and a backward switch (not shown) for discharging the gas are provided. Here, the amount of gas injected by turning on the forward switch and the amount of gas discharged by turning on the backward switch are set to be substantially the same. The amount of gas to be injected or discharged is the horizontal direction of the rust preventive film sheet 80 where the operation roll starting positions Xa, Xb of the support rolls 40a, 40b described above and the support rolls 40a, 40b are at the peeling operation position O. A predetermined gas amount for swinging the swing arms 24a and 24b is set so that the support rolls 40a and 40b move one way between positions on the outside (hereinafter referred to as operation stop positions Ya and Yb). .

  On the other hand, the above-mentioned holder placement portion 13 of the apparatus main body 11 has a movable member that is urged upward in the placement reference hole 12 and is movable in the vertical direction, as shown in FIGS. 37 is disposed. Further, a switch 38 that is turned on when the movable member 37 moves downward is disposed below the movable member 37. As shown in FIGS. 10A to 10B, the movable member 37 is moved downward by the positioning projection 5 when the positioning projection 5 of the sheet holder 2 is inserted into the arrangement reference hole 12. It is pressed and moves downward. Then, as shown in FIG. 10B, when the rust preventive film sheet 80 held by the sheet holder 2 is disposed at the peeling operation position O, the movable member 37 is stopped and held at this position. . The switch 38 is turned on at the position where the movable member 37 is stopped. The switch 38 drives a suction device (not shown) by turning on the switch 38. As described above, the suction device is configured so that the vacuum nozzles 43 of the support rolls 40a and 40b and the tilting members 32 and 32 are provided. Each is connected to a vacuum nozzle 34. That is, when the rust preventive film sheet 80 is disposed at the peeling operation position O, the switch 38 is turned on to drive the suction device, the vacuum nozzles 43 and 34 are suctioned, and the suction pads 42 and 33 are Adsorb to the release paper 83. Here, the position of the movable member 37 that turns on the switch 38 is the operating position (see FIGS. 10B and 10C). Further, the position where the movable member 37 is stopped by its upward biasing force, such as when the positioning protrusion 5 of the sheet holder 2 is not inserted into the arrangement reference hole 12, is the open position (FIG. 10). (See (A)). The switch 38 is deactivated when the movable member 37 moves away from the operating position, and stops driving the suction device.

Next, a series of operations for peeling off the release paper 83 from the rust preventive film sheet 80 using the release paper peeling device 1 described above will be described in accordance with the work order.
For example, it is assumed that a large number of rust preventive film sheets 80 are stacked and placed on standby with the opposite surface 81b of the adhesive surface 81a of the rust preventive film 81 as the upper side (not shown). In this standby state, a cylindrical insertion tube is disposed in the center of the rust preventive film sheet 80 along the stacking direction (vertical direction) (not shown). This insertion cylinder is arranged so as to open upward. Moreover, the rust prevention film sheet 80 has specified the circumferential direction position so that each separating line 84 and 84 may overlap in the lamination direction in the above-described standby state.

  An operator grasps the grip portion 4 of the sheet holder 2 and presses the sheet holder 2 from above on the rust-proof film sheet 80 in the standby state (not shown). At this time, the positioning protrusion 5 can be positioned at the center of the anticorrosive film sheet 80 by inserting the positioning protrusion 5 of the sheet holder 2 into the insertion tube described above. Then, by pressing the sheet holder 2, the plurality of adhesive portions 6 disposed on the lower surface side of the base 3 are bonded to the upper surface (opposite surface 81 b) of the rust-proof film sheet 80, and the rust-proof film sheet 80. Hold. Here, the sheet holder 2 can hold the rust-proof film sheet 80 in a planar shape because the plurality of adhesive portions 6 have the buffer material 6b and are arranged radially. Then, by lifting the sheet holder 2, a single rust preventive film sheet 80 is taken out from a standby state where a large number of sheets are laminated.

  As shown in FIG. 10A, the operator inserts the positioning protrusion 5 into the arrangement reference hole 12 of the apparatus main body 11 in the sheet holder 2 that holds the antirust film sheet 80 as described above. As shown in FIG. 10B, it is attached to the apparatus main body 11. Thereby, the rust preventive film sheet 80 held by the sheet holder 2 is positioned at the peeling operation position O of the apparatus main body 11. Here, in this embodiment, by adjusting the circumferential position of the sheet holder 2, the anticorrosion film sheet 80 held by the sheet holder 2 is separated from the release line 83 of the release paper 83. , 84 are positioned at the peeling operation position O so as to be substantially along the arrangement reference line L described above (see FIG. 8).

  In addition, in the state where the rust prevention film sheet 80 is arranged in the peeling operation position O in this way, the release paper 83 of the rust prevention film sheet 80 is pressed upward by the upper part of the roll surface of the support rolls 40a and 40b. ing.

  Thus, when the rust prevention film sheet 80 is arrange | positioned in the peeling operation position O, as for the apparatus main body 11, the support rolls 40a and 40b exist in the operation start position Xa and Xb (refer FIG. 12 (A)), and the tilting member 32 , 32 suction pads 33, 33 are in the suction position (see FIG. 13A). As described above, when the positioning protrusion 5 of the sheet holder 2 is inserted into the placement reference hole 12 and the rust preventive film sheet 80 is positioned at the peeling operation position O, the movable member in the placement reference hole 12 is placed. 37 is pushed down from the open position (see FIG. 10A) to the operating position (see FIG. 10B). As a result, the switch 38 is turned on, the suction device (not shown) starts to be driven, and the suction pads 33 and 42 are sucked onto the release paper 83. That is, the suction pads 42 of the support rolls 40a and 40b are sucked to the side of the separation lines 84 and 84 of the large divided areas 85 and 85 of the release paper 83 of the anticorrosive film sheet 80, respectively. On the other hand, the suction pads 33, 33 of the tilt members 32, 32 are sucked to the inner ends of the divided small areas 86, 86 of the release paper 83, respectively.

  Then, the forward switch (not shown) of the cylinder 27 is turned on. As a result, the cylinder 27 moves forward, and the swing arms 24a and 24a swing, and the swing arms 24b and 24b swing according to the interlocking arms 26 and 26, respectively. As in B), the support rolls 40a and 40b move while rotating from the operation start positions Xa and Xb to the operation stop positions Ya and Yb, respectively. Further, the tilting members 32 and 32 are tilted by the swinging of the swinging arms 24a and 24a, and the suction pads 33 and 33 are moved from the suction position to the arrangement reference as shown in FIGS. Tilt downward along line L.

  Here, as the roll rotation shafts 41a and 41b move according to the guide rails 14 and 14, the support rolls 40a and 40b are rotated by the pinion gear 21 of the roll rotation shafts 41a and 41b by the rack gear 20. It moves while rotating from the operation start positions Xa and Xb to the operation stop positions Ya and Yb. Since these support rolls 40a and 40b move while rotating so as to roll on the lower surface of the anticorrosive film sheet 80, they are adsorbed by the respective adsorption pads 42 as shown in FIGS. The divided large region 85 is advanced so as to wind up, and the divided large region 85 is peeled off from the adhesion surface 81 a of the rust-proof film 81. The suction pads 42 of the support rolls 40a and 40b are adsorbed along the separation lines 84 and 84 at the operation start positions Xa and Xb, on the side of the separation lines 84 and 84, as described above. Therefore, when the rotation and movement are started, the edges of the release paper divided large areas 85 and 85 along the separation lines 84 and 84 are pulled relatively smoothly from the adhesive surface 81a of the anticorrosive film 81. Can be peeled off.

  Then, as shown in FIGS. 12B to 12D, the support rolls 40a and 40b move while rotating from the operation start positions Xa and Xb, thereby gradually winding the divided large areas 85 and 85. Then, the divided large regions 85 and 85 are sequentially peeled off from the rust preventive film 81 until the operation stop positions Ya and Yb. Thus, in the process in which the support rolls 40a and 40b wind up the divided large areas 85 and 85, the support rolls 40a and 40b advance through the divided large areas 85 and 85 while rolling the lower surface of the release paper 83. It is pressed upwards sequentially in the direction. For this reason, the divided large regions 85 and 85 of the release paper 83 are peeled off from the rust preventive film 81 on the rear side (placement line L side) from the portion pressed against the support rolls 40a and 40b. Further, a force for winding the release paper 83 is prevented from acting on the front side (the side opposite to the arrangement reference line L) from the pressed portion. This prevents the release paper 83 from being displaced along the horizontal direction so that the release paper 83 is not peeled off from the rust prevention film 81 and the rust prevention film 81 is torn. Therefore, the support rolls 40a and 40b move while rotating from the operation start positions Xa and Xb to the operation stop positions Ya and Yb, thereby breaking the rust preventive film 81 or bonding the adhesion surfaces 81a to each other. Therefore, the large divided areas 85 and 85 of the release paper 83 can be reliably peeled off from the rust preventive film 81.

  In this embodiment, the gear ratio between the rack gear 20 and the pinion gear 21 is adjusted, and the rotation speed of the support rolls 40a and 40b is higher than the movement speed of the support rolls 40a and 40b. It is set to be slow. Accordingly, as shown in FIG. 12C, the release paper 83 can be slackened between the portion where the roll surfaces of the support rolls 40a and 40b press the release paper 83 and the suction pads 42 and 42. it can. In this case, since the force which peels off the divided large areas 85 and 85 from the rust preventive film 81 is small in the component acting vertically downward and the component acting in the lateral direction outward is increased, the rust preventive film 81. It is easy to scrape the large divided area 85 smoothly without exerting an excessive force.

  On the other hand, when the swing arms 24a and 24b swing due to the above-described forward movement of the cylinder 27, the tilt members 32 and 32 are tilted along with the swing, as shown in FIGS. The suction pads 33 and 33 sucked by the divided small areas 86 and 86 of the pattern 83 are tilted downward along the arrangement reference line L from the suction position. Thereby, the divided small regions 86 and 86 are gradually peeled off from the adhesive surface 81a of the rust preventive film 81 from the inner portion toward the outer portion. Here, the divided small regions 86 and 86 are peeled off from the rust preventive film 81 by being pulled downward from the inner portion toward the outer side. Since the divided small regions 86 and 86 have a relatively long and narrow shape, the suction pads 33 and 33 can be surely peeled off without breaking the rust preventive film 81 or bonding the bonding surfaces 81a to each other. Can be.

  As described above, the support rolls 40a and 40b and the tilting members 32 and 32 operate in synchronism with each other according to the forward operation of the cylinder 27 as shown in FIGS. Therefore, by operating the cylinder 27 by turning on the forward switch (not shown), the divided large areas 85 and 85 and the divided small areas 86 and 86 of the release paper 83 of the anticorrosive film sheet 80 are At almost the same time, it can be peeled off from the rust preventive film 81. According to this release paper peeling apparatus 1, the release paper 83 can be removed from the rust-preventing film sheet 80 in a shorter time compared to the case where the release paper 83 is peeled off sequentially for each divided area by the operator's manual work. Can be peeled off. Furthermore, the release paper 83 is peeled off without causing a failure such as the rust prevention film 81 being broken or the adhesive surfaces 81a being bonded to each other, which occurs when the operator manually peels off the release paper 83. be able to. The release paper peeling apparatus 1 of this configuration is capable of reliably and efficiently peeling off the release paper 83 which is formed with the separation line 84 and can be divided and peeled off from the rust preventive film sheet 80. .

  On the other hand, when the release paper 83 is peeled off as described above, the operator removes the sheet holder 2 from the apparatus main body 11 as shown in FIG. That is, the sheet holder 2 is pulled upward, and the positioning protrusion 5 is extracted from the arrangement reference hole 12 of the apparatus main body 11. Thereby, the movable member 37 in the arrangement reference hole 12 returns from the operating position (see FIG. 11D) to the open position (see FIG. 11E). By the movement of the movable member 37, the ON operation of the switch 38 is released. In accordance with the release of the ON operation of the switch 38, the suction operation of a suction device (not shown) is stopped, and the divided large regions 85 and 85 are dropped from each suction pad 42 as shown in FIG. Thereafter, a return switch (not shown) of the cylinder 27 is turned on to cause the cylinder 27 to return as shown in FIG. 11F, whereby the support rolls 40a and 40b are moved to the operation stop positions Ya and Yb. To the operation start positions Xa and Xb. On the other hand, even in the suction pads 33, 33 of the tilt members 32, 32, the suction of the suction device according to the release of the ON operation of the switch 38 in a state where the divided small regions 86, 86 are peeled off (see FIG. 13C). When the operation is stopped, the divided small areas 86 and 86 are dropped (not shown). Then, the suction pads 33, 33 of the tilt members 32, 32 are returned to the suction positions (see FIG. 13A) in accordance with the ON operation of the return switch (not shown) of the cylinder 27. Thus, when the support rolls 40a and 40b return to the operation start positions Xa and Xb and the tilting members 32 and 32 return to the suction position, the preparation for the operation of peeling the release paper 83 from the rust prevention film sheet 80 is ready. It will be. That is, as described above, the sheet holder 2 holds the next rust-proof film sheet 80 and places the rust-proof film sheet 80 in the peeling operation position O. The stripping operation can be performed again.

  In the present embodiment, the release paper peeling device 1 is provided with a bag (not shown) for catching the divided large areas 85 and 85 and the divided small areas 86 and 86 dropped from the suction pads 33 and 42. The large divided areas 85 and 85 and the small divided areas 86 and 86 can be easily collected.

  As described above, the operator removes the sheet holder 2 holding the rust preventive film 81 from the apparatus main body 11 and then carries it to the vehicle wheel to which the rust preventive film 81 is attached (not shown). Then, the positioning protrusion 5 is inserted into the hub hole from above the design surface side of the vehicle wheel, and the sheet holder 2 is pressed against the design surface. Thereby, the adhesion surface 81a of the antirust film 81 currently hold | maintained at the sheet | seat holder 2 is affixed on the design surface of a vehicle wheel. Thereafter, by lifting the sheet holder 2 from the vehicle wheel, the rust preventive film 81 bonded to each adhesive portion 6 of the sheet holder 2 was peeled off, and the rust preventive film 81 was adhered to the design surface. Held in a state. In this way, the rust preventive film 81 can be attached to the design surface of the vehicle wheel 81 so as to cover all the decorative holes. Here, as described above, the sheet holder 2 includes the adhesive portions 6 radially around the positioning protrusions 5 to be inserted into the hub holes, and the adhesive portions 6 have a buffering action by the buffer material 6b. Therefore, the rust preventive film 81 can be appropriately affixed to the uneven design surface so as to completely cover all the decorative holes of the vehicle wheel.

  And after affixing the antirust film 81 to the design surface of the wheel for vehicles, by holding the antirust film sheet 80 from the place where it was laminated by the sheet holder 2 in the standby state again, it was mentioned above. Thus, the work of peeling off the release paper 83 can be performed again. In this way, the release paper 83 can be peeled off from the anticorrosion film sheet 80 and the antirust film 81 can be attached to the vehicle wheel, so that the release paper peeling apparatus 1 is a conveyor that sequentially transfers the vehicle wheel. Etc. and set so that this series of operations is performed as a line operation, the productivity of the vehicle wheel to which the rust preventive film 81 is joined can be greatly enhanced.

  Thus, in the release paper peeling apparatus 1 of the present embodiment, the operator holds the rust-proof film sheet 80 on the sheet holder 2, arranges the rust-proof film sheet 80 at the peeling operation position O, and sets the cylinder 27. The release paper 83 can be peeled off from the rust preventive film sheet 80 relatively easily and surely only by executing the operation.

  In this release paper peeling apparatus 1, it is possible not to have the structure which act | operates by the exchange of an electrical signal at all. For example, in the above-described suction device (not shown) that exhibits suction force for sucking the suction pads 33 and 42 to the release paper 83, a configuration in which negative pressure is generated in a pipe called an ejector using a Venturi pipe. The air supply control to the piping is performed by a mechanical valve including a switch 38 that is turned on and off by the movable member 37 described above. The cylinder 27 is driven by a push-type mechanical valve. Such a release paper peeling apparatus 1 has the advantages that no external power is required, no electrical failure occurs, and the apparatus itself can be made relatively compact. The installation location can be set relatively freely. Furthermore, since the operator is engaged in the operation of directly handling the sheet holder 2 and the operation of operating each switch (not shown) of the cylinder 27, the release paper peeling apparatus 1 is appropriately operated. It also has an excellent advantage of being able to respond quickly even if a problem occurs. The release paper peeling apparatus 1 may be configured such that predetermined components exchange electrical signals or require external power.

  Further, the release paper peeling apparatus 1 appropriately adjusts the operation start positions Xa and Xb of the respective support rolls 40a and 40b and the suction positions of the suction pads 33 of the tilting members 32 and 32, thereby preventing various sizes of rust prevention. The film sheet 80 can be supported. Accordingly, it is possible to relatively easily cope with the rust-proof film sheet 80 having a shape corresponding to the vehicle wheel having a different rim diameter, and the release paper 83 can be peeled off reliably and efficiently as described above.

  In the embodiment described above, the cylinder 27 is disposed to swing the swing arms 24a, 24a. However, as another configuration, the operating arms 24a, It can also be set as the structure which rotates the support shaft of 24a. For example, it is assumed that a tread plate is connected to the support shafts of the operating arms 24a and 24a, and when the operator steps on the tread plate, the support shaft rotates to swing the operating arms 24a and 24a. Even in this configuration, as described above, the support rolls 40a and 40b can be moved from the operation start positions Xa and Xb to the operation stop positions Ya and Yb, and the suction pads 33 and 33 of the tilt members 32 and 32 can be tilted. The release paper 83 can be reliably and efficiently peeled off from the rust-proof film sheet 80. In this configuration, since the suction pads 33 and 42 are all performed by the operator's action, no electrical problems occur and the installation location is further facilitated. It can be set. Further, in this configuration, it is preferable to arrange a member such as a spring that urges the operating arms 24a, 24a in this direction so as to return the operating arms 24a, 24a to their original positions.

  Further, in the above-described embodiment, the release paper 84 of the rust prevention film sheet 80 is divided into four parts. However, even if the number of divisions of the release paper is different, the release paper is surely secured. It is possible to peel it off. For example, in the donut-shaped rust preventive film sheet 80 similar to the embodiment, it is assumed that the release paper is formed with a single separation line along its radial direction. That is, the release paper can be divided into two parts and peeled off. As the release paper peeling device for peeling the release paper from the rust-proof film sheet, it is assumed that the operating rod 31, the tilting member 32, the suction pad 33 and the like are not provided in the configuration of the above-described embodiment. And the suction pad of each support roll adsorbs to the both sides of the separation line of the release paper, and the release paper can be separated into two parts by moving each support roll while rotating.

  Further, in the above-described embodiments, the sheet holder 2 is used to hold the rust-proof film sheet 80, or to place the rust-proof film sheet 80 at the peeling operation position O. This is a configuration that is performed by an operator, but this can also be automated. For example, by connecting a sheet holder to a robot arm or the like, holding the rust-proof film sheet, placing the rust-proof film sheet at the peeling operation position O, attaching the rust-proof film to a vehicle wheel, etc. It can be executed by controlling the driving of the arm. Here, the operation of the cylinder 27 can also be controlled in conjunction with the driving of the robot arm, so that the work of attaching the rust preventive film to the vehicle wheel can be almost completely automated.

  In the above-described embodiment, the rust preventive film sheet 80 has been described using a donut-shaped configuration having no gripping protrusions. Even if the peripheral edge is provided with a gripping protrusion protruding outward, the release paper can be reliably and efficiently peeled off as described above. And the release paper peeling apparatus 1 of this invention is the same also in the structure which was in the rust prevention film sheet provided with the grip protrusion, and the arrangement | positioning position in the dimension shape and outer periphery of this grip protrusion is variously set. It is possible to exert the effects of. In addition, this rust-proof film sheet has various shapes such as a circular shape or a donut shape and a different outer peripheral shape, assuming that it is attached to the design surface of a vehicle wheel. However, the release paper can be peeled off by the release paper peeling device 1. Here, as the shape of the rust-proof film sheet, for example, a shape having a plurality of gripping protrusions on the outer periphery, a shape having gripping protrusions of various dimensions, a shape having a recess on the outer periphery, etc. Can be handled appropriately. Thus, the release paper peeling apparatus 1 concerning this invention has the outstanding convenience.
