However, in Patent Document 1, each time a sheet is attached, the release sheet temporarily attached to the sheet must be peeled off. For this reason, there is an inconvenience that the burden of work required for peeling increases, and the entire work time becomes long for performing the peeling work. In addition, the operation of collecting and discarding the release sheet is complicated and laborious, and the cost for disposing of the release sheet is also incurred.
By the way, if only the sheet from which the release sheet is peeled is held by the adsorption member, the sheet is thin and has low rigidity, so that the regularity cannot be maintained and a large number of wrinkles are generated before holding. For this reason, it is extremely difficult and unrealistic to hold the sheet at an appropriate position of the suction member while eliminating the sheet wrinkles.

[Object of invention]
An object of the present invention is to provide a sheet holding device and a sheet sticking device that can prevent sheet wrinkling without using a release sheet and can easily hold a sheet at an appropriate position.

Note that terms indicating the direction or position in this specification are used for “lower” in FIG. 1 and “rear” for the upper side in FIG. 1 unless otherwise specified. Further, “left” and “right” are based on FIG. 1, and “upper” and “lower” are based on FIG.
Further, in the present specification and claims, the “reversed position” means a position where the sheet is reversed so that it is raised immediately after being peeled off from another sheet, as shown in FIG. means.

  1 to 4, the holding device 10 includes a base 11, a first holding means 13 provided above the base 11, a second holding means 14 provided on the first holding means 13, and a base 11 and a first holding means 13. The peeling means 16 is provided between the first holding means 13 and the first holding means 13.

  The base 11 has a shape that is long to the left and right, and a plurality of sheets S are arranged on the upper surface thereof. Each sheet S has an adhesive layer AD on one surface (the upper surface in FIG. 2) of the base sheet BS, and is formed in a substantially circular shape in accordance with the shape of the wheel in order to be attached to the wheel of the automobile. A shaft passage SC is provided in the central portion. Each sheet S is laminated by directly bonding the other surface (lower surface in FIG. 2) of the base sheet BS to an adhesive layer of another sheet S adjacent below. As a result, when the sheet S is thin and has low rigidity, the regularity cannot be maintained as a single sheet S unless the release sheet is temporarily attached to the adhesive layer as in the prior art. By directly bonding and stacking S, a plurality of sheets S can be handled as one unit without temporarily attaching the release sheet to the adhesive layer. As shown in FIG. 1, the sheet S includes a held area SA formed so as to protrude from a circular outer periphery on the right edge side, and a holding hole SH is formed in the center of the held area SA. The held area SA may or may not have an adhesive layer. Here, on the upper surface of the uppermost sheet S, a peeling assisting means 18 made of a roller is provided. The peeling assisting means 18 has an axis extending in the front-rear direction, and a non-adhesion treatment is performed on the surface thereof with a fluororesin, a silicone resin (silicon resin) or the like so that the adhesive layer does not adhere. Both ends of the peeling assisting means 18 are provided so as to engage with grooves (not shown) provided in the frame 37. Further, a stopper 19 is provided on the base 11 and on the right side of the sheet S. As shown in FIG. 1, the stopper 19 is provided so as to be able to contact the peeling assisting means 18 located on the right end side of the sheet S, and the peeling assisting means 18 can be positioned with the position as an initial position. ing.

  The first holding means 13 has a lower surface as the suction surface 20, and a suction pad 21 that can suck and hold the other surface of the base sheet BS in the sheet S, that is, the opposite surface of the adhesive layer AD, and the suction pad 21. The support plate 22 is supported from above, the handle 24 is provided in the center of the upper surface of the support plate 22, and the positioning means 25 is provided below the handle 24.

  The suction pad 21 is formed in a substantially circular shape like the sheet S. The suction pad 21 includes a number of holes (not shown) in the suction surface 20, and the holes are connected to a suction pump (not shown) via a hose 27.

  The positioning means 25 penetrates the handle 24 and can be operated with a fingertip, an axial member 31 that can be moved in and out from the suction surface 20, and an operation for moving the axial member 31 in and out by operating the operating unit 30. And a mechanism 32. The shaft-shaped member 31 is provided so as to be fitted in a concave hub formed on the wheel, and the first holding means 13 can be positioned when the sheet S is pasted by the fitting. The operation mechanism 32 uses a magnet (not shown) and a compression coil spring as an urging means, so that the operation unit 30 and the shaft-shaped member 31 approach each other inside the operation mechanism 32, and the shaft-shaped member 31 can move in and out. Is adopted. Inside the operation mechanism 32, the shaft-like member 31 is provided so as to be slidable and to fall by its own weight. When the shaft-like member 31 is buried, it is magnetically attached by a magnet so that it does not fall due to its own weight and the force of the compression coil spring. On the other hand, when the operation unit 30 is pressed, the sum of the pressing force and the force of the compression coil spring is obtained. The shaft-shaped member 31 protrudes downward because it is larger than the magnetic force of the magnet. In addition, since the shaft-shaped member 31 is provided with a compression coil spring, even if the shaft-shaped member 31 is used upward in a state where the shaft-shaped member 31 protrudes, the weight of the shaft-shaped member 31 is reduced. It will not be buried because an elastic biasing force is applied so as not to be buried. Therefore, no inconvenience is caused even if the shaft-shaped member 31 is used upward.

  The second holding means 14 is formed of a shaft-like body and is provided on a bracket 34 that hangs down from the lower surface on the left end side of the support plate 22. The second holding means 14 protrudes leftward from the bracket 34 and is provided so as to be able to be inserted into the holding hole SH. The second holding means 14, the holding hole SH of the sheet S on the base 11, the center of the sheet S, and the center of the suction pad 21 are aligned in the front-rear direction and are provided in a straight line in the left-right direction. Yes.

  The peeling means 16 includes moving means 36 provided on both the front and rear sides of the sheet S on the base 11. Each moving means 36 includes a pair of frames 37 extending left and right and oriented in the vertical direction, and a plurality of rollers 38 arranged in parallel on the left and right between the frames 37 and rotatable. The lower surface of the support plate 22 is placed above each moving means 36, and the relative movement between the base and the first holding means 13 is urged by the rolling of the rollers 38, and the first holding means 13 is straight in the left-right direction. Will move. A guide plate 40 is provided on the lower surface of the support plate 22 so as to be parallel to the frame 37 so as to restrict the movement of the first holding means 13 in the front-rear direction.

  Next, a method for holding the sheet S to the holding device 10 and a method for attaching the sheet S to the wheel will be described.

  First, as shown in FIGS. 1 and 2, the first holding means 13 is arranged on the right side of the sheet S, and the adhesive layer of the stacked sheets S is installed on the top surface. Further, the peeling assisting means 18 is placed on the upper surface on the right end side of the uppermost sheet S. From this state, as shown in FIG. 3A, the first holding means 13 is manually moved leftward by the operator via the moving means 36 while the held area SA of the uppermost sheet S faces upward. It moves and inserts the second holding means 14 into the holding hole SH. As a result, the right edge side of the sheet S is held by the second holding means 14.

  Thereafter, when the operator manually moves the first holding means 13 to the left, the uppermost sheet S is reversed while being held by the second holding means 14, and the other sheets S below the uppermost sheet S are reversed. It is peeled off. At this time, as shown in FIG. 3B, the peeling assisting member 18 is positioned along the reversal position inside the reversed sheet S. As a result, the sheet S is pressed by the peeling assisting member 18 at the reversal position, and generation of wrinkles of the sheet S immediately after peeling is suppressed.

  The sheet S peeled by the movement of the first holding means 13 is sucked and held on the suction pad 21 sequentially from the peeled and inverted region. At this time, since the sheet S to be sucked and held is reversed, the adhesive layer AD of the sheet S faces downward, and the opposite surface that is not the adhesive layer AD is held in surface contact with the suction pad 21. Accordingly, the separation and holding of the sheet S are performed at substantially the same timing, and the region where the sheet S is held by the suction pad 21 while maintaining a state in which the sheet S is partially bonded to the other sheet S below the sheet S. Will be gradually expanded. Here, the peeling assisting member 18 has both ends of the peeling assisting member 18 engaged with a groove (not shown) provided in the frame 37, and the reversing position of the sheet S according to the progress of the reversing position of the sheet S in the left direction. Roll to the left while maintaining a state along Thus, the holding of the sheet S by the peeling assisting member 18 is maintained until the holding of the sheet S is completed.

  As shown in FIG. 3C, when the suction pad 21 passes through the sheet S on the base 11, all the areas of the sheet S are separated from the other sheets S, and the position where the sheet S is displaced from the suction pad 21. The holding to the suction pad 21 is completed without being held by the pad. When the peeling assisting member 18 rolls to a position where the entire area of the sheet S is peeled from the other sheet S, the engaged peeling assisting means 18 is further depressed than a groove (not shown) provided in the frame 37. It hooks into the deep groove provided in the state. After the holding of the sheet S is completed, the first holding means 13 is lifted from above each moving means 36 in order to stick the sheet S to the wheel as an adherend, and the operator operates the operation unit 30 to operate the shaft-shaped member 31. Projecting from the suction surface 20. Next, the protruding shaft-shaped member 31 is fitted into the wheel hub to position the first holding means 13 in the left-right and front-rear directions, and the adhesive layer of the sheet S held by the suction pad 21 is pressed against the wheel. S is pasted (see FIG. 4).

  The suction pad 21 is released after the application of the sheet S is completed, and the suction pad 21 exhibits the same holding force as that of the suction due to the self-viscosity of the suction pad 21 or static electricity of the sheet S. As long as the sheet S can be held by the pad 21, it may be before the sheet S is pasted.

  In addition, after the work of attaching the sheet S to the wheel is completed, the right side of the sheet S in FIG. 1 is the initial position after the operator manually embeds the shaft-like member 31 that remains protruding. By disposing the first holding means 13 in one cycle, one cycle of the work process is completed. Thereafter, the holding method and the pasting method described above are sequentially repeated.

  Therefore, according to such an embodiment, even when the sheet S is thin and does not maintain the regularity in a no-load state, the sheet S is held on the suction pad 21 in a state where wrinkles are generated, or the sheet S is Thus, the sheet S can be prevented from being held at a position shifted from the position 21, and the sheet S can be held easily and smoothly. Further, the sheet S can be easily and smoothly positioned with respect to the suction pad 21 even when the sheet S is thin and the release sheet is only the peeled sheet S. And since it is not necessary to use a peeling sheet, the work burden accompanying the said use and a cost burden can be reduced, and it also becomes possible to shorten work time.

As described above, the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this.
In other words, the present invention has been illustrated and described mainly with respect to specific embodiments, but without departing from the scope of the technical idea and object of the present invention, the shape, position, or With respect to the arrangement and the like, those skilled in the art can make various changes as necessary.
Therefore, the description limited to the shape disclosed above is an example for easy understanding of the present invention, and does not limit the present invention. The description by the name of the member which remove | excluded one part or all part is included in this invention.

  For example, the second holding means 14 can be variously modified, such as increasing according to the number of holding holes SH formed, or making the holding means SA by holding the held area SA. When the holding means is used, it is possible to hold even a perfect circle in which the held area SA does not exist in the shape of the sheet S. At that time, the sheet S in which the held area SA does not exist may or may not have the holding hole SH. Further, the second holding means 14 may be provided separately from the first holding means 13 without being provided.

  Further, the second holding means 14 is provided to be able to protrude from the bracket by the driving means in order to save the labor of removing the held area SA from the second holding means 14 after the operator completes the pasting of the sheet S to the wheel. Also good.

  Further, the peeling assisting means 18 may be formed in a plate shape as long as the same effect as in the above embodiment is exhibited.

  Further, the peeling means 16 moves the base 11 manually without moving the first holding means 13 or moves both the base 11 and the first holding means 13 manually to move them relative to each other. May be. In short, it is sufficient that the peeling means 16 is provided so as to be able to peel the sheet S as in the above embodiment. For example, the peeling means 16 may move only the base 11 without moving the first holding means 13 or move both the base 11 and the first holding means 13 to move them relative to each other. Good. The method of moving the first holding means 13 and the second holding means 14 relative to the base 11 may be automatically performed via a driving means such as a motor or a cylinder other than manually.

  Further, when the operator attaches the sheet S to the wheel, the support plate is used for the purpose of visually confirming the insertion of the shaft-like member 31 into the concave hub formed on the wheel. In addition to being formed of a transparent acrylic material or the like, the support plate 22 may have a hollow portion.

  Further, in order to more reliably peel off and attach the sheet S, it is possible to switch between suction and blowing by the suction pad 21 by installing a switching means in this apparatus. At that time, by using a fan motor or the like as an air source of the blowing means, it is possible to blow air when the sheet S is stuck.

  In addition, a stop means for stopping the suction of the suction pad 21 may be connected to the apparatus after the suction pad 21 has started to be sucked in order for the operator to attach the sheet S to the wheel. For example, when the sheet S is stuck on the wheel, if the worker has the first holding means 13 in his hand and it is difficult to work with his hand, it is stopped for convenience of work. The means may be a stepping button.

  In addition, after the peeling process of the sheet S, the peeling assisting member 18 is manually returned to the initial position shown in FIG. 1, that is, the right side of the stacked sheets S, and the air cylinder, hydraulic cylinder, and rodless for returning automatically. Actuators such as cylinders and rotary cylinders, and coil springs and spring members may be connected.

  Further, in order to facilitate the holding by bringing the holding holes of the stacked sheets S close to the second holding means 14, the horizontally stacked sheets S can be tilted or moved up and down while keeping the sheets S horizontal. Adjustment means such as an adjustment screw may be connected to the base 11.

  Further, the sheet S to be attached to the adherend need not be limited to the wheel sheet as in the embodiment. That is, a sheet having an arbitrary use and shape to be attached to an adherend, such as any other sheet, film, or tape, can be applied. For example, as for the shape of the sheet S, the shaft opening may not be opened in the central portion of the sheet S as in the embodiment. In that case, when the apparatus positions the sheet S, the shaft-like member 31 does not have to protrude from the suction surface 20.

  Further, the relative movement direction is not limited to the horizontal direction as in the first holding unit 13 and the second holding unit 14 and the sheet S shown in the embodiment. For example, the vertical direction may be a vertical movement.

  Further, when the sheet S is installed on the base 11, the adhesive layer AD of the stacked sheets S may be directed downward. In this case, the reversing means 45 is used so that the adhesive layer AD of the sheet S when held by the first holding means 13 is held downward (see FIG. 5). The reversing unit 45 includes a roller that is wound around the sheet S while sandwiching the separation assisting unit 18 and the sheet S and reverses the front and back of the sheet S. The reversing means 45 rolls up the sheet S to reverse the front and back of the sheet S, and then the sheet S is pressed by the peeling assisting member 18 and sucked and held by the suction pad 21.

  In the embodiment, the suction pad 21 has a circular shape. However, as long as the sheet S can be sucked and held, the shape may not be particularly circular. For example, as a shape other than a circle, a regular polygon such as a square, or a shape including a polygon or a curve may be used.

  Further, the biasing means (not shown) provided in the shaft-shaped member 31 is not limited to the compression coil spring, and other biasing means may be used. For example, a torsion coil spring, a leaf spring, a disc spring, a ring spring, a tension coil spring, and the like can be employed, and these may be combined directly or indirectly.

  Furthermore, the sheet sticking device is configured to include the holding device 10 according to the embodiment and the sticking means that can move the first holding means 13, and the sheet S held on the suction pad 21 by the operation of the sticking means is used as a wheel. You may affix and stick to. The drive equipment that constitutes the affixing means employs electric equipment such as rotary motors, linear motion motors, linear motors, single-axis robots, articulated robots, actuators such as air cylinders, hydraulic cylinders, rodless cylinders, and rotary cylinders. In addition, they consist of a combination of them directly or indirectly.

  Further, the peeling assisting member 18 may move left and right by being connected to an air cylinder, a hydraulic cylinder, a rodless cylinder, a rotary cylinder, and the like. Further, the peeling assisting member 18 is directly connected to the output shaft that has come out of the hollow motor or the like, and is connected via a gear or the like, so that the peeling assisting member 18 is rotationally driven so as to promote the peeling of the sheet S. Also good.

  In the embodiment, the case where the peeling assisting member 18 is used has been described, but the peeling assisting member 18 may not be particularly used. For example, by reducing the gap between the suction surface 20 of the first holding unit 13 and the stacked sheets S as much as possible, the area of the sheet held by the first holding unit 13 and the lower surface of the first holding unit 13 are reduced. If a certain suction surface 20 is parallel, it can be held. The gap can be held by adjusting it appropriately according to the rigidity of the sheet S.

  In the embodiment, the adherend of the sheet S is an automobile wheel. However, the adherend need not be limited to an automobile wheel. For example, in addition to wheels for automobiles, other plate-like members such as a glass plate, a steel plate, or a resin plate, and those other than plate-like members can also be targeted. And the wheel for motor vehicles can illustrate an aluminum wheel etc.
