  However, in the prior art, as shown in the sheet mounting apparatus 100 according to the reference example of FIG. 3, the sheet SH is bent while the sheet SH is being fed from the feeding means 102 to the support means 101. There is a case. In particular, when a sheet with weak rigidity or a sheet on which a cut line or a fold line (hereinafter collectively referred to as a “cut and fold line”) such as a perforation, a broken line, a dent groove, or a marking line is fed out The sheet SH is likely to be bent due to the dynamic friction between the surface of the support means 101 and the sheet SH, and the sheet SH in a wrinkled state is attached to the adherend, or the sheet SH falls from the support means 101. Invite poor mounting.

  Further, as shown in FIG. 3, the sheet SH is bent such that the sheet SH is reversed as shown by a two-dot chain line, even if measures such as providing means 103 for blowing air from below the support means 101 are taken. It may be difficult to properly prevent the bending state of the material from worsening.

  An object of the present invention is to solve the problem of bending of a sheet when it is drawn out on a support surface, and a sheet with wrinkles is attached to an adherend or the sheet falls from a support means.

Direction, “left” is the X-axis arrow direction, “right” is the opposite direction, “front” is the Y-axis arrow direction, and “rear” is the opposite direction.

  The sheet mounting apparatus 10 includes a feeding unit 20 that feeds out the adhesive sheet AS as a sheet, and a supporting unit that supports the adhesive sheet AS from the non-adhesive surface Asa side, which is one surface of the fed adhesive sheet AS, by the support surface 34a. 30 and mounting means 40 for mounting the supported adhesive sheet AS on an adherend WK such as a corrugated cardboard case or a semiconductor wafer.

  The feeding means 20 folds back the support shaft 21 that supports the original fabric RS in which the adhesive sheet AS having a predetermined shape is temporarily attached on the strip-shaped release sheet RL, a plurality of guide rollers 22, and the release sheet RL. A release plate 23 for peeling the adhesive sheet AS from the release sheet RL, a drive roller 25 that is rotationally driven by a rotation motor 24 as a drive device, and a pinch roller 26 that sandwiches the release sheet RL between the drive roller 25; It is configured by a collection roller 27 that is driven by a driving device (not shown) and collects the release sheet RL. Note that the feeding direction of the adhesive sheet AS by the feeding means 20 is the left direction. Further, the adhesive sheet AS has a multilayer structure (two-layer structure) including an adhesive layer AD and a base sheet BS, and the upper surface of the base sheet BS is a non-adhesive surface Asa.

The support means 30 sucks and supports the adhesive sheet AS, and ejects gas from the non-adhesive surface Asa side of the adhesive sheet AS, so that the adhesive sheet AS is fed in the feeding direction. Sheet feeding means 32 for applying a feeding force.
The suction unit 31 includes a decompression unit 33 such as a decompression pump or a vacuum ejector that generates a negative pressure, and a decompression box 34 having a decompression space 34 d that is decompressed by the decompression unit 33 inside. Is a support surface 34a, and a suction hole 34b communicating with the decompression space 34d is formed in the support surface 34a.
The sheet feeding means 32 is formed on the support surface 34a as a circulation means connected to the exhaust side of the decompression means 33 via the gate valve 35, and as a gas ejected via the pipe 36. A concave groove 37 as a gas rectifying means capable of forming exhaust gas as an air current including a component in the feeding direction of the adhesive sheet AS, an airflow direction adjusting means 38 provided in the concave groove 37 and capable of adjusting the direction of the airflow, and a concave A shutter 39 is provided at the left end portion of the groove 37 and can be moved up and down by a driving means (not shown), and serves as a pressing auxiliary means for eliminating a partial insufficient pressing force of the adhesive sheet AS by the concave groove 37. The concave grooves 37 are formed along the feeding direction of the adhesive sheet AS, and a plurality of the concave grooves 37 are formed in the Y-axis direction as shown in FIG.
A plurality of airflow direction adjusting means 38 are provided in the respective recessed grooves 37 at predetermined intervals along the X-axis direction, and are supported so as to be rotatable about a rotation shaft 38b parallel to the Y-axis. An air guide plate 38a having a fan-shaped cross-sectional shape and a driving device (not shown) for rotating the air guide plate 38a in the XZ plane are provided.

  The mounting means 40 is constituted by a linear motion motor 41 as a drive device, and its output shaft 42 is connected to the upper surface of the decompression box 34.

  Next, the operation of the sheet mounting apparatus 10 according to the first embodiment will be described. First, as shown in FIG. 1A, the raw fabric RS is set in the feeding means 20, and when an operation start signal is input through an operation panel (not shown), the suction means 31 drives the decompression means 33. At the same time, suction starts at the suction hole 34b, and an air flow is generated in the concave groove 37 through the pipe 36 and the gate valve 35 connected to the exhaust side of the decompression means 33. At this time, the gate valve 35 adjusts the pressure (amount) of the gas fed into the concave groove 37 using the output from the pressure detection means such as a pressure sensor (not shown). Thus, by circulating the exhaust of the decompression means 33 and generating an air flow in the concave groove 37, it is not necessary to separately provide a pressurization means such as a pressurization pump or a turbine for generating the airflow. It is possible to prevent the apparatus from becoming large and to prevent the control from becoming complicated, and the exhaust energy of the decompression means 33 can be reused.

  Next, when the adherend WK conveyed by the conveying means CV such as a belt conveyor stops at a predetermined position below the decompression box 34, the feeding means 20 drives the rotation motor 24 and rotates the drive roller 25 to release the release sheet. By pulling RL, the raw fabric RS is fed out and the adhesive sheet AS is fed out at the left end edge of the peeling plate 23. The fed adhesive sheet AS moves along the support surface 34a while being sucked by suction by the suction holes 34b. At this time, the adhesive sheet AS is given a feeding force by an air flow generated in the concave groove 37 in addition to a feeding force from the portion of the adhesive sheet AS that has not been peeled off from the release sheet RL. That is, as shown by the arrow AR1, the gas ejected from the pipe 36 becomes an air flow in the feeding direction of the adhesive sheet AS by passing through the concave groove 37, and adheres to the adhesive sheet AS fed from the feeding means 20. The feeding force is applied in the feeding direction of the sheet AS. Thereby, it is possible to suppress a problem that the adhesive sheet AS is bent due to a dynamic frictional resistance or the like generated between the non-adhesive surface ASa of the adhesive sheet AS and the support surface 34a. In addition, since the sheet feeding unit 32 generates an air flow, it is possible to avoid a risk that the adhesive sheet AS is strongly attracted to the support surface 34a and the dynamic frictional resistance is increased.

  Further, the airflow direction adjusting means 38 drives a driving device (not shown) as necessary, changes the angle of the air guide plate 38a, adjusts the direction of the airflow in the concave groove 37, and feeds as shown by an arrow AR2. The airflow flowing in the direction can have a component toward the adhesive sheet AS direction. Thereby, it can suppress that adhesive sheet AS is drawn in into the ditch | groove 37. FIG. Each airflow direction adjusting means 38 can be controlled independently, and the support means 30 provided with such airflow direction adjusting means 38 can be used even when the adhesive sheet AS is bent locally. It is possible to solve this problem by partially adjusting the direction.

When the adhesive sheet AS is delivered to the decompression box 34, after the feeding means 20 stops driving the rotation motor 24, the mounting means 40 drives the linear motion motor 41 to lower the support means 30, and the adhesive sheet AS. To attach to the adherend WK. At this time, the sheet feeding means 32 activates a driving device (not shown), lowers the shutter 39 and pressurizes the inside of the concave groove 37 with the gas ejected from the pipe 36, and the partial pressing force of the adhesive sheet AS by the concave groove 37. Eliminate shortages.
After the adhesive sheet AS is mounted on the adherend WK, the suction unit 31 stops the decompression unit 33 and the support unit 30 stops the force to support the adhesive sheet AS. Furthermore, the mounting means 40 drives the linear motion motor 41 and raises the support means 30. Thereafter, the adherend WK on which the adhesive sheet AS is mounted is transported to the next step or the like by the transport means CV, and thereafter the same operation as described above is repeated.

  According to the embodiment as described above, the problem that the adhesive sheet AS is bent while the adhesive sheet AS is fed from the feeding means 20 to the support means 30 can be solved. In particular, even when the adhesive sheet AS having a low rigidity or the adhesive sheet AS formed with a cut and fold line is fed out, the problem that the adhesive sheet AS is bent is effectively suppressed, and the adhesive sheet AS in a state in which wrinkles enter. Can be prevented from being mounted on the adherend WK, or the adhesive sheet AS can be dropped from the support means 30.
