JP 2016-50034 A

In the sheet sticking device 10 (sheet sticking device) described in Patent Document 1, a holding surface 43 (supporting means) for holding an adhesive sheet AS (adhesive sheet) and an adhesive sheet on an adherend WK (adherend). Since both the holding plate 42 (pressing means) to be pressed is integrated into the pressing means, there is an inconvenience that the degree of freedom in designing the supporting means and the pressing means is lost.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sheet sticking device and a sheet sticking method that can prevent loss of flexibility in designing support means and pressing means.

The present invention employs the configurations described in the claims.

According to the present invention, the adhesive sheet is supported by the supporting means with a predetermined gap, and the adhesive sheet is passed through the gap by the pressing means to be attached to the adherend. It is possible to suppress the loss of flexibility in designing the support means and the pressing means without concentrating on the pressing means.
Further, if the pressing member that presses the adhesive sheet to pass through the gap is configured to press the supporting region of the adhesive sheet against the adherend, it is possible to eliminate the insufficient pressing force of the adhesive sheet against the adherend.

Furthermore, in the present embodiment, when viewed from the front side of FIG. In terms of direction, "left" is the direction of the arrow on the X axis and "right" is the opposite direction, and "front" is the direction of the arrow on the Y axis and "back" is the opposite direction.

The sheet sticking apparatus EA includes a delivery means 10 for carrying out a delivery step of delivering the adhesive sheet AS, and supports the adhesive sheet AS delivered by the delivery means 10 with a predetermined gap CL in the plane of the adhesive sheet AS. Supporting means 20 for carrying out a supporting step, and pressing means 30 for carrying out a pressing step of passing the adhesive sheet AS supported by the supporting means 20 through the gap CL and pressing it against the adherend WK to attach it, It is arranged in the vicinity of the conveying means 40 that conveys the adherend WK.

Feeding means 10 includes a support roller 11 that supports the original sheet RS to which the adhesive sheet AS is temporarily adhered to one surface of the release sheet RL, a guide roller 12 that guides the original sheet RS, and a release edge 13A that separates the release sheet RL. The release sheet RL is sandwiched between a peeling plate 13 as peeling means for peeling the adhesive sheet AS from the peeling sheet RL and a pinch roller 14B supported by an output shaft (not shown) of a rotation motor 14A as a driving device. While the sheet sticking apparatus EA is supported by the drive roller 14 and the output shaft of a drive device (not shown), a predetermined tension is always applied to the release sheet RL between the pinch roller 14B and the pinch roller 14B. , and a recovery roller 15 as recovery means for recovering the release sheet RL.

The support means 20 has a pair of L-shaped brackets 21 arranged on the right side of the peeling plate 13 of the delivery means 10 .
Each bracket 21 is provided with a sheet supporting portion 21A extending from one bracket 21 toward the other bracket 21. A gap CL is formed between these sheet supporting portions 21A, and the feeding means 10 is provided on the upper surfaces of both sheet supporting portions 21A. to support the adhesive sheet AS fed out.

The pressing means 30 is supported by a linear motor 32 as a driving device supported by an output shaft 31A of a direct-acting motor 31 as a driving device, and two sliders 32A of the linear motor 32, respectively, to press the adhesive sheet AS. and a pressing member 33 for passing through the gap CL.
In this embodiment, the pressing member 33 is configured to press the support region AS1 of the adhesive sheet AS, which is supported by the support means 20, against the adherend WK.

The transport means 40 includes a conveyor 41 such as a belt conveyor or a roller conveyor for transporting the adherend WK.

The operation of the above sheet sticking apparatus EA will be described.
First, a user of the sheet sticking device EA (hereinafter simply referred to as the "user") moves the sheet sticking device EA in which the respective members are arranged at the initial positions indicated by the solid lines in FIG. After the raw fabric RS is set in the machine, a signal for starting automatic operation is inputted through an operation means such as an operation panel (not shown) or a personal computer. Then, the feeding means 10 drives the rotary motor 14A to feed the original sheet RS, and as shown in FIG. When the predetermined position is reached, the rotation motor 14A is stopped.

Next, the conveying means 40 drives the conveyor 41 to convey the adherend WK rightward, and as shown in FIG. 1A, when the adherend WK reaches a predetermined position below the pressing member 33 Stop driving the conveyor 41 . After that, the delivery means 10 drives the rotary motor 14A, and when the leading end of the adhesive sheet AS next to the leading adhesive sheet AS in the delivery direction reaches a predetermined position in the vicinity of the peeling edge 13A of the peeling plate 13, the rotary motor is driven. Stop driving 14A. As a result, the leading adhesive sheet AS is peeled off from the release sheet RL, and as shown in FIG. 1A and FIG. 21A. Next, the pressing means 30 drives the direct-acting motor 31 to lower the pressing member 33 and press the adhesive sheet AS to close the gap CL as indicated by the two-dot chain lines in FIGS. Then, the adhesive sheet AS is pressed and adhered to the adherend WK. Then, the pressing means 30 drives the linear motor 32 to move the pressing member 33 back and forth as shown in FIG. Next, the pressing means 30 drives the linear motor 31 and the linear motor 32 to return the pressing member 33 to the initial position. After that, the conveying means 40 drives the conveyor 41 to convey the adherend WK to the right toward the next step, and the same operation as described above is repeated thereafter.

According to the embodiment as described above, the adhesive sheet AS is supported by the supporting means 20 with a predetermined gap CL, and the adhesive sheet AS is passed through the gap CL by the pressing means 30 to be attached to the adherend WK. Therefore, both the supporting means 20 and the pressing means 30 are not integrated into the pressing means, and it is possible to prevent the loss of freedom in designing the supporting means 20 and the pressing means 30 .

As described above, the best configuration, method, etc. for carrying out the present invention are disclosed in the above description, but the present invention is not limited thereto.
