Description

The present invention relates to a sheet supplying device and a sheet supplying method, as well as a sheet application device and a sheet application method.

A sheet supplying device is known that feeds a roll of paper with an adhesive sheet temporarily attached to a release sheet, and then peels the adhesive sheet off of the release sheet and supplies it (see, for example, Patent Document 1).

JP 2005-104518 A

In the printer 1 (sheet supply device) described in Patent Document 1, the already peeled portion of the IC label 52 (adhesive sheet) that has been peeled off from the backing paper 51 (release sheet) is temporarily reattached to the release sheet by a pressing member 8 (re-attaching member) that rotates around an eccentric shaft 14. Depending on the length of the already peeled portion of the adhesive sheet and the shape of the re-attaching member, the leading end of the adhesive sheet in the payout direction may not be pressed by the re-attaching member and may remain peeled off from the release sheet. In such a case, after the re-attaching member is returned to its initial position, the adhesive sheet that has been temporarily re-attached to the release sheet may peel off from the release sheet, which creates the inconvenience of requiring the work of removing the peeled adhesive sheet.

The object of the present invention is to provide a sheet supplying device and a sheet supplying method, as well as a sheet attachment device and a sheet attachment method, that can prevent the need to remove a peeled adhesive sheet.

The present invention employs the configuration described in the claims.

According to the present invention, the re-temporary attachment member is moved along the release sheet folded back by the peeling means, and the adhesive sheet is re-temporarily attached to the release sheet by the re-temporary attachment member, so that the adhesive sheet re-temporarily attached to the release sheet does not peel off from the release sheet, and the task of removing the peeled adhesive sheet can be prevented.

Furthermore, in this embodiment, the view from the front direction of Fig. 1(A) parallel to the Y-axis is used as a reference, and when indicating directions, "up" is the direction of the Z-axis arrow, "down" is the opposite direction, "left" is the direction of the X-axis arrow, "right" is the opposite direction, "front" is the front direction in Fig. 1(A) parallel to the Y-axis, and "rear" is the opposite direction.

The sheet supplying device EA is equipped with a pay-out means 10 which performs a pay-out process of paying out an original roll RS having an adhesive sheet AS temporarily attached to one side of a release sheet RL, a peeling plate 20 as a peeling means which performs a peeling process of folding back the release sheet RL of the original roll RS paid out by the pay-out means 10, peeling the adhesive sheet AS from the release sheet RL and supplying it, and a re-temporary attachment means 30 which performs a re-temporary attachment process of folding the adhesive sheet AS peeled off by the peeling plate 20 in the folding direction of the release sheet RL, and re-temporarily attaching the adhesive sheet AS to the release sheet RL.
The sheet application apparatus EA1 includes a sheet supplying apparatus EA, a moving means 40 that performs a moving process of moving the adherend WK and the sheet supplying apparatus EA relative to one another, and a pressing means 50 that performs a pressing process of pressing an adhesive sheet AS against the adherend WK to apply it thereto.

The unwinding means 10 includes a base plate 11 that directly or indirectly supports the components that make up the unwinding means 10, a support roller 12 that supports the original roll RS, a guide roller 13 that guides the original roll RS, a drive roller 14 that is supported by an output shaft (not shown) of a rotary motor 14A as a driving device and that pinches the original roll RS between itself and the pinch roller 14B, and a recovery roller 15 that is supported by an output shaft (not shown) of the driving device and that constantly applies a predetermined tension to the release sheet RL that exists between itself and the pinch roller 14B while the sheet application device EA1 is in automatic operation, and serves as a recovery means for recovering the release sheet RL.

The re-temporary attachment means 30 includes a linear motor 31 as a driving device, a linear motor 32 as a driving device supported by a slider 31A of the linear motor 31, a table 33 supported by an output shaft 32A of the linear motor 32 and having a support surface 33A that can be adsorbed and held by a pressure reducing means (holding means) such as a pressure reducing pump or a vacuum ejector (not shown), and a re-temporary attachment roller 34 as a re-temporary attachment member that is rotatably supported by the table 33 via a bracket 34A, moves along the release sheet RL folded back by the release plate 20, and re-temporarily attaches the adhesive sheet AS to the release sheet RL. In this embodiment, the re-temporary attachment means 30 also serves as the moving means 40.

In this embodiment, the moving means 40 doubles as the re-temporary attachment means 30, and the moving means 40 is equipped with the re-temporary attachment means 30.

The pressing means 50 includes a linear motor 51 as a driving device and a pressing roller 52 rotatably supported on the output shaft 51A of the linear motor 51.

The operation of the sheet sticking apparatus EA1 equipped with the above-mentioned sheet supplying apparatus EA will be described.
First, the user of the sheet application device EA1 (hereinafter, simply referred to as the "user") sets the original roll RS on the sheet application device EA1, in which each member is arranged at the initial position shown by the solid line in Fig. 1A, as shown in the figure, and then inputs a signal to start checking the payout of the original roll RS via an operation means (not shown), such as an operation panel or a personal computer. Then, the payout means 10 drives the rotary motor 14A to perform a payout checking operation to pay out a predetermined length of the original roll RS. As a result, if it is necessary to adjust the meandering of the original roll RS or adjust the stop position of the adhesive sheet AS as pre-operation adjustment, the user adjusts the mounting angle and mounting position of each roller, such as the guide roller 13, the drive roller 14, and the pinch roller 14B, so that the original roll RS does not meander, or adjusts the stop timing and the like (not shown) of a sensor that detects the adhesive sheet AS and stops the payout of the original roll RS, so that the adhesive sheet AS stops at an appropriate position.

In addition, when the detection means, which is composed of an imaging means such as a camera or a projector, or various sensors such as an optical sensor or an ultrasonic sensor, detects that the leading end of the adhesive sheet AS in the payout direction has been peeled off from the release sheet RL as a result of the payout confirmation operation being performed, as shown by the two-dot chain line in Fig. 1(A), the re-temporary attachment means 30 drives the linear motor 31 and the linear motor 32 to lower the table 33 and then move it to the left. Next, as shown by the two-dot chain line in Fig. 1(A), when the re-temporary attachment roller 34 reaches a position to the left of the already peeled portion AS1 of the adhesive sheet AS, the re-temporary attachment means 30 drives the linear motor 31 and the linear motor 32 to move the re-temporary attachment roller 34 above the already peeled portion AS1 of the adhesive sheet AS, as shown in Fig. 1(B). Thereafter, the re-temporary attachment means 30 drives the linear motor 32, and as shown by the two-dot chain line in Fig. 1(B) , lowers the re-temporary attachment roller 34 to fold the already peeled portion AS1 of the adhesive sheet AS downward, and then drives the linear motor 31 and the linear motor 32 to move the re-temporary attachment roller 34 along the release sheet RL folded back by the peeling plate 20, and the re-temporary attachment roller 34 re-temporarily attaches the already peeled portion AS1 of the adhesive sheet AS to the release sheet RL. Next, when the pre-operation adjustment is completed and the user inputs a signal to confirm the end of the payout confirmation of the original web RS via an operation means not shown, the re-temporary attachment means 30 drives the linear motor 31 and the linear motor 32 to return the table 33 to its initial position. When the user inputs a signal to start automatic operation via an operating means (not shown), the payout means 10 drives the rotary motor 14A to pay out the original roll RS, and as shown in FIG. 1(C), when the leading end of the leading adhesive sheet AS in the payout direction after payout confirmation is peeled off a predetermined length by the peeling edge 20A of the peeling plate 20, the drive of the rotary motor 14A is stopped.

Next, when the user or a conveying means such as an articulated robot or a belt conveyor (not shown) places the adherend WK at a predetermined position on the support surface 33A, the moving means 40 drives the decompression means (not shown) to start suction and holding the adherend WK on the support surface 33A. After that, the pressing means 50 drives the linear motor 51 to lower the pressing roller 52 as shown by the two-dot chain line in FIG. 1 (C). Next, the moving means 40 drives the linear motor 31 to move the table 33 to the left, and when the table 33 reaches a predetermined position, the unwinding means 10 drives the rotating motor 14A to unwind the original roll RS in accordance with the moving speed of the table 33. As a result, the leading adhesive sheet AS is peeled off from the release sheet RL at the peeling edge 20A of the peeling plate 20, and the adhesive sheet AS peeled off from the release sheet RL is pressed by the pressing roller 52 to the adherend WK as shown by the two-dot chain line in FIG. 1 (C) and affixed.

When the entire adhesive sheet AS is attached to the adherend WK and the leading end of the next adhesive sheet AS following the leading adhesive sheet AS in the payout direction is peeled off by a predetermined length at the peeling edge 20A of the peeling plate 20, the payout means 10 stops driving the rotary motor 14A. Then, when the table 33 reaches a predetermined position to the left of the pressure roller 52, the moving means 40 stops driving the linear motor 31, then stops driving the pressure reducing means (not shown), and releases the suction and holding of the adherend WK on the support surface 33A. Next, when the user or the conveying means (not shown) conveys the adherend WK with the adhesive sheet AS attached to it to the next process, the moving means 40 drives the linear motor 31 to return the table 33 to its initial position, and the same operations as above are repeated thereafter.

According to the above embodiment, the reattachment roller 34 is moved along the release sheet RL folded back by the peel-off plate 20, and the adhesive sheet AS is reattached to the release sheet RL by the reattachment roller 34. This prevents the adhesive sheet AS reattached to the release sheet RL from peeling off from the release sheet RL, and prevents the need to remove the peeled adhesive sheet AS.

As described above, the best configurations, methods, etc. for implementing the present invention have been disclosed in the above description, but the present invention is not limited thereto. In other words, the present invention has been mainly illustrated and described with reference to specific embodiments, but those skilled in the art can make various modifications to the above-described embodiments in terms of shape, material, quantity, and other detailed configurations without departing from the scope of the technical idea and purpose of the present invention. Furthermore, the descriptions limiting the shapes, materials, etc. disclosed above are provided as examples to facilitate understanding of the present invention, and do not limit the present invention. Therefore, descriptions of the names of components that remove some or all of the limitations on the shapes, materials, etc. are included in the present invention.

For example, the unwinding means 10 may unwind the raw roll RS in which a closed-loop or entire short-width slit is formed in a strip-shaped adhesive sheet base material temporarily attached to a strip-shaped release sheet RL, and a predetermined area partitioned by the slit is made into the adhesive sheet AS, or a strip-shaped adhesive sheet base material in which a strip-shaped adhesive sheet base material is temporarily attached to a strip-shaped release sheet RL may be used, and in the course of unwinding the strip-shaped adhesive sheet base material, a closed-loop or entire short-width slit is formed in the adhesive sheet base material by a cutting blade as a cutting means, and the raw roll RS in which a predetermined area partitioned by the slit is made into the adhesive sheet AS may be unwound. The original roll RS may be unwound, for example, from a fan-folded original roll RS, or a recovery means may be used to recover the release sheet RL by folding it fan-fold without winding it, shredding it with a shredder, or piling it up randomly, or a recovery means may not be used. When a signal indicating that the unwounding of the original roll RS has been confirmed is input, the original roll RS may be wound up in the direction of the support roller 12, and the adhesive sheet AS temporarily reattached to the release sheet RL may be moved upstream of the peeling edge 20A in the original roll unwinding direction.

The re-temporary attachment means 30 may be provided with, for example, a linear motor as a driving device supported by a slider or table 33 separate from the slider 31A in the linear motor 31, instead of or in combination with the linear motor 32, and a re-temporary attachment roller 34 may be rotatably supported on the output shaft of the linear motor.
The re-temporarily attaching means 30 may be provided with a folding member separate from the re-temporarily attaching member. In this case, for example, the re-temporarily attaching means 30 may be provided with a linear motor as a driving device configured separately from the moving means 40, and a folding roller as a folding member rotatably supported on the output shaft of the linear motor. The linear motor may be driven to fold the already peeled portion AS1 of the adhesive sheet AS with the folding roller, and then the linear motor 31 and the linear motor 32 may be driven to move the re-temporarily attaching roller 34 along the release sheet RL folded back by the peeling plate 20 to re-temporarily attach the adhesive sheet AS to the release sheet RL. Alternatively, the linear motor supporting the folding roller and the folding roller may be positioned upstream of the peeling edge 20A of the peeling plate 20 in the original web pay-out direction, and these may be moved downstream of the peeling edge 20A of the peeling plate 20 in the original web pay-out direction by a driving device such as a linear motor, and then the already peeled portion AS1 of the adhesive sheet AS may be folded by the folding roller.
The re-temporary attachment means 30 does not have to be used together with the moving means 40, and may, for example, be equipped with a first linear motor as a driving device, a folding roller as a folding member rotatably supported on the output shaft of the first linear motor, a second linear motor as a driving device having an output shaft parallel to the release sheet RL folded back by the peel-off plate 20, and a re-temporary attachment roller as a re-temporary attachment member rotatably supported on the output shaft of the second motor, and after driving the first linear motor to fold the already peeled portion AS1 of the adhesive sheet AS with the folding roller, the second linear motor is driven to move the re-temporary attachment roller along the release sheet RL folded back by the peel-off plate 20, thereby re-temporarily attaching the adhesive sheet AS to the release sheet RL.
The re-temporary attachment means 30 may also be used as the pressing means 50. In this case, for example, the already peeled portion AS1 of the adhesive sheet AS may be folded using a pressing roller 52 as a bending member, or a driving device may be provided for moving the linear motor 51 so that the output shaft 51A is parallel to the release sheet RL folded over by the peel-off plate 20, and after moving the linear motor 51, the linear motor 51 may be driven to move the pressing roller 52 as a re-temporary attachment member along the release sheet RL folded over by the peel-off plate 20, thereby re-temporarily attaching the adhesive sheet AS to the release sheet RL.
The re-attaching member and the folding member may be composed of a round bar, a blade material, a brush-like member, rubber, resin, sponge, etc., or may be composed of a gas blowing member such as a nozzle or a spray pipe connected to a gas supply means such as a pressure pump turbine, and the adhesive sheet AS may be folded by blowing a gas such as air or nitrogen gas onto the adhesive sheet AS with the gas blowing member, or the adhesive sheet AS may be re-temporarily attached to the release sheet RL.

The moving means 40 does not have to be used as the temporary reattaching means 30 , in which case the temporary reattaching roller 34 does not have to be supported by the table 33 .
The moving means 40 may be a table 33 that cannot be adsorbed and held on the support surface 33A, or may move the sheet supplying device EA without moving the substrate WK or while moving it, and may be provided in the sheet supplying device EA or sheet application device EA1 of the present invention, or may not be provided, and if not provided, the substrate WK may be moved by another device.

The pressing means 50 may be configured to include a linear motor as a driving device and a holding member that is supported by the output shaft of the linear motor and can be adsorbed and held by a decompression means (not shown), such as a decompression pump or a vacuum ejector, and press the adhesive sheet AS held by the holding member onto the adherend WK to adhere it thereto. Alternatively, the pressing means 50 may be arranged upside down or horizontally together with the sheet supplying device EA and the moving means 40 to press the adhesive sheet AS onto the underside or side of the adherend WK to adhere it thereto. Alternatively, a driving device may be used as a pressing member contact means for moving the pressing roller 52 away from and toward the adherend WK to prevent stress or damage to the adherend WK. The sheet supplying device EA or the sheet applying device EA1 of the present invention may or may not be provided with the pressing means. If the pressing means 50 is not provided with the pressing means 52, the adhesive sheet AS may be pressed onto the adherend WK and adhered thereto by another device.

The sheet supply device EA may supply the adhesive sheet AS peeled off from the release sheet RL to a device other than the pressing means 50, for example, a printing device that prints on the adhesive sheet AS, an inspection device that inspects the condition of the adhesive sheet AS, or a user.

The material, type, shape, etc. of the adhesive sheet AS and the adherend WK are not particularly limited. For example, the adhesive sheet AS and the adherend WK may be circular, elliptical, polygonal such as a triangle or a square, or other shape, and the adhesive sheet AS may be pressure-sensitive, heat-sensitive, or other adhesive form. When a heat-sensitive adhesive sheet AS is used, the adhesive sheet AS may be adhered by an appropriate method such as providing a heating means such as a suitable coil heater or the heating side of a heat pipe to heat the adhesive sheet AS. In addition, such an adhesive sheet AS may be, for example, a single layer of only an adhesive layer, a two-layered one in which a substrate and an adhesive layer are laminated, a three-layered one or more layers in which one or more intermediate layers are laminated between the substrate and the adhesive layer, a three-layered one or more layers in which one or more cover layers are laminated on the upper surface of the substrate, a substrate, an intermediate layer, or a cover layer is provided in a peelable manner, a double-sided adhesive sheet of a single layer consisting of only an adhesive layer, a double-sided adhesive sheet in which an adhesive layer is laminated on both outermost surfaces of one or more intermediate layers, etc. Furthermore, the adherend WK may be, for example, a single object such as food, a resin container, a semiconductor wafer such as a silicon semiconductor wafer or a compound semiconductor wafer, a circuit board, an information recording substrate such as an optical disk, a glass plate, a steel plate, a ceramic plate, a wooden board, or a resin, or may be a composite formed of two or more of these, and may also be a member or an article of any shape. Note that the adhesive sheet AS may be read in terms of its function and use, for example, any sheet, film, tape, etc., such as an information label, a decorative label, a protective sheet, a dicing tape, a die attach film, a die bonding tape, or a recording layer-forming resin sheet.

The means and steps of the present invention are not limited in any way so long as they can perform the operations, functions or steps described for those means and steps, and are in no way limited to the components and steps of just one embodiment shown in the above embodiment. For example, the pay-out means may be anything that pays out a roll of base material with an adhesive sheet temporarily attached to one side of a release sheet, and is not limited in any way so long as it is within the technical scope in light of the common general technical knowledge at the time of filing (the same goes for the other means and steps).
