Examples of the sheet SS include a sheet-like printing paper, a multi-layered sheet member in which an adhesive sheet is laminated on a release sheet, and a bag-like one such as an envelope. Here, in the stacked sheet body SS, the sheet body SS located at the outermost part (uppermost) is the outermost sheet body SS1, and the sheet body SS adjacent to the lower surface of the outermost sheet body SS1 is the adjacent sheet. The body SS2.

  The placing means 11 includes a bottom portion 16 and a vertical wall 17 which is provided upright from the bottom portion 16 and surrounds the stacked sheet bodies SS, and an inner peripheral surface 17A of the vertical wall 17 is a laminated surface. It is located along SA.

  The conveying means 12 includes a support 20 such as a suction pad, a Bernoulli chuck, a chuck cylinder, and a mechanical chuck that can support the upper surface of the outermost sheet SS1, a support shaft 21 that supports the support 20, and a support shaft 21. The first linear motion motor 24 as a driving device that serves as a displacement means that can move the slider 23 in the left-right direction is connected to the first linear motion motor 24 that is positioned on the left and right. And a second linear motion motor 28 as a drive device that supports the connecting member 25 at the tip end side of the output shaft 27 and can move the output shaft 27 in the vertical direction. A linear motion motor 28 is supported via a slider 30, and a third linear motion motor 31 is provided as a drive device that can move the slider 30 in the front-rear direction. Accordingly, the conveying means 12 can convey the outermost sheet member SS1 by moving the outermost sheet member SS1 in the three orthogonal axes by the operation of the linear motion motors 24, 28, 31. The vertical length of the support shaft 21 and the stroke length of the second linear motion motor 28 are set longer than the vertical length of the inner peripheral surface 17A of the vertical wall 17.

  The adhesion preventing means 14 is formed in a linear shape extending vertically on the chamber 33 formed inside the bottom portion 16, the airflow generating means 34 connected to the chamber 33, and the inner peripheral surface 17 </ b> A of the vertical wall 17, A plurality of grooves 36 communicating with the chamber 33 on the lower end side, and a step surface 37 formed in an upper region of the inner peripheral surface 17A located on the right side of the stacked sheet body SS are provided. The step surface 37 is formed parallel to, that is, horizontally, the relative surface of the outermost sheet body SS1 and the adjacent sheet body SS2, and the inner peripheral surface 17A above the step surface 37 is separated from the laminated surface SA by the lower inner peripheral surface 17A. It is formed at a distant position. The left end edge 37A of the step surface 37 functions as a cutting edge.

  The air flow generation means 34 includes an intake pipe 39 communicating with the chamber 33 and suction means (not shown) such as an intake pump and a vacuum ejector connected to the intake pipe 39, and the chamber 33 passes through the groove portion by the operation of the suction means. It is designed to inhale inside. During this intake, airflow is generated in each groove portion 36, and it is possible to generate airflow in a direction from the outermost sheet body SS1 side to the adjacent sheet body SS2 side, that is, in a downward direction, at a position along the lamination surface SS1. It becomes.

  Three grooves 36 are formed on the inner peripheral surface 17A on both the left and right sides of the stacked sheet body SS and one on the inner peripheral surface 17A on both the front and rear sides, and are positioned along the laminated surface SA. . An oblique airflow generation means 41 is provided on the upper end side of each groove 36. The oblique airflow generation means 41 is formed by making the upper end region of the groove portion 36 an inclined surface that inclines in a direction away from the sheet body SS as it goes upward. As a result, the airflow generation means 41 can generate an oblique airflow 41A that flows in the direction of pressing downward while moving inward from the edge of the sheet body SS when the airflow is generated in the groove portion 36. Note that the left end edge 37 </ b> A of the step surface 37 may be provided below the oblique airflow generation means 41. Thereby, since it becomes easy to blow an air current on the upper surface of the exposed adjacent sheet member SS2, it is effective to release the adhesion between the outermost sheet member SS1 and the adjacent sheet member SS2.

  Next, a method for supplying the sheet body SS according to the embodiment will be described.

  First, a plurality of sheet bodies SS are stacked on the bottom portion 16. In this state, a suction means (not shown) is communicated with the chamber 33 via the intake pipe 39 to generate an air flow in the direction of the arrow in FIG. Thereby, the airflow which goes to the adjacent sheet body SS2 side from the outermost sheet body SS1 generate | occur | produces in the position along the lamination surface SA, and the force which goes below is provided to the several sheet body SS laminated | stacked on the bottom part 16. FIG. It will be.

  The support 20 is arranged and supported on the upper surface of the outermost sheet member SS1 by the operation of the linear motors 24, 28, 31 while allowing the air flow to pass through the groove 36. Subsequently, the support body 20 and the outermost sheet body SS1 supported by the support body 20 are raised by the operation of the second linear motion motor 28. As shown in FIG. 2, when the outermost sheet member SS1 passes through the stepped surface 37, the first linear motor 24 is operated to displace the outermost sheet member SS1 in the right direction. Thereby, when the adjacent sheet body SS2 is attached to the outermost sheet body SS1, the right edge of the adjacent sheet body SS2 is abutted against the left edge 37A of the step surface 37, and the upper surface of the left end side of the adjacent sheet body SS2 is Express. And the slant airflow 41A generated by the slant airflow generation means 41 is sprayed on the upper surface of the left side of the adjacent sheet body SS2 that is exposed, the adjacent sheet body SS2 is urged downward and falls, and the outermost sheet body SS1 and Adhesion with the adjacent sheet SS2 is released.

  After the adhesion between the outermost sheet member SS1 and the adjacent sheet member SS2 is released, the outermost sheet member SS1 is conveyed to a predetermined position by the operation of each of the linear motion motors 24, 28, 31 and the support by the support member 20 is released. This completes the supply of the outermost sheet SS1. And since the above-mentioned adjacent sheet body SS2 is located in the outermost surface part next time, this will be repeated by using this as the outermost sheet body SS1.

  Therefore, according to such an embodiment, the adhering of the adjacent sheet body SS can be released by the air current, so that it is not necessary to use a member that contacts the edge of the sheet body SS for releasing the adhering. . As a result, the sheet body SS can be prevented from being deformed or damaged, and the quality of the sheet body SS can be improved. In addition, the sheet SS laminated on the bottom portion 16 always generates an air flow along the lamination surface SA during standby of conveyance, and thus hardly adheres to the adjacent sheet SS2 before conveyance of the outermost sheet SS1. This makes it possible to better suppress the adhesion.

In the groove part 36 in these drawings, a part of the air current is easily blown out of the groove part 36 when the air stream passing through the inside hits the refracting part 36A or the curved part 36B. Thereby, it is possible to generate a large amount of interlayer airflow that flows from the laminated surface SA in the in-plane center direction of the sheet body SS, and it is possible to better prevent adhesion between adjacent sheet bodies SS. The refracting portion 36A and the bending portion 36B are formed so that the groove becomes shallower toward the outside of the refraction or bending, so that the airflow is likely to blow out to the outside of the groove portion 36 due to inertia, and the interlayer airflow is easily generated. be able to.
