Such sheet materials are in close contact with each other, and even if only the uppermost sheet material is lifted, a plurality of sheet materials may be lifted by the suction action by the vacuum of the contact surfaces of the sheet materials.

  Such separation of the sheet material is achieved by turning up the end of the sheet material to create a gap in a part between the sheet material and the sheet material in contact with the lower surface, and the sheet material and the lower surface thereof. This is realized by enlarging the gap between the sheet material in contact with the sheet material.

  As an apparatus for generating a gap in a part between the sheet material and the sheet material in contact with the lower surface thereof, there is a sheet material separating apparatus described in JP-A-2001-205373.

It is the side view which has arrange | positioned the sheet | seat material separation auxiliary | assistance apparatus of FIG. 1 on the both sides of the laminated | stacked sheet | seat material.

  Hereinafter, the laminated sheet material 100 from which the uppermost sheet material 101 is separated by the sheet material separation apparatus having the sheet material separation assisting apparatus 1 according to the embodiment of the present invention will be described.

  The laminated sheet material 100 shown in each drawing may be made of, for example, a nonmagnetic metal such as aluminum. The X-axis direction of the coordinate axes in the figure is the stacking direction. The Y direction of the coordinates in the drawing is a direction in which the sheet material separating auxiliary member 2 and the like to be described later approach and leave toward the end of the sheet material 100 laminated.

  1 to 7, the end of the laminated sheet material 100 opposite to the sheet material separation auxiliary device 1 side is in contact with, for example, a stopper or the like, and the laminated sheet material 100 is Y It does not move greatly in the axial direction.

  In the sheet material 100 made of a nonmagnetic metal such as aluminum, a lubricating oil or the like is applied and laminated on the smooth surface of the sheet material 100. Such laminated sheet materials 100 may be in close contact with each other. For example, even when only the uppermost sheet material 101, which is a specific sheet material, is lifted, the lower sheet material sticks to the uppermost sheet material 101 due to the vacuum adsorbing action of the contact surface with the lower sheet material. May be lifted in a state.

  When such a plurality of sheet materials are stuck to each other and transported to the processing device in the next process, there is a possibility that the processing device in the next process may fail or a processing failure may occur. Therefore, it is necessary to reliably separate only the uppermost sheet material 101 from the laminated sheet material 100.

  When the laminated sheet material 100 is made of a non-magnetic metal or the like, a method of separating the uppermost sheet material 101 by magnetism cannot be used.

  Even for a sheet material made of a non-magnetic metal or the like, there is a method of separating the sheet materials by blowing air between the sheet material. However, if the separation of the sheet material is achieved by blowing air, a large amount of air is consumed, and the energy consumption increases.

  In order to reduce energy consumption, the method of abutting against the edge of the sheet material and turning up the edge of the sheet material causes the edge to be cut and the powder to adhere to the sheet material, resulting in processing failure in the processing device in the next process. May occur.

  A sheet material separation assisting apparatus 1 according to an embodiment of the present invention that can solve these problems will be described below.

The turning motion is guided. The trajectory of this turn is on the same plane parallel to the XY plane of the coordinate axes in the figure.

  As the sheet material separation assisting member 2 approaches and leaves, the turning center C of the sheet material separation assisting member 2 is displaced in the Y axis direction orthogonal to the X axis direction, which is the stacking direction.

  The second linear motion member 4 is connected to a cylinder rod 52 a of a cylinder 52 fixed to the housing 5. When the cylinder 52 is actuated, the cylinder rod 52a expands and contracts, and can approach and leave toward the end of the sheet material 100 on which the second linear motion member 4 is laminated.

  The second linear motion member 4 includes a linear guide 41. The first linear motion member 3 is fixed to a block 42 that moves along the linear guide 41. The linear guide 41 and the block 42 guide the linear reciprocating motion of the first linear motion member 3.

  Hereinafter, the operation of the sheet material separation auxiliary device 1 will be described.

FIG. 1 shows a state before the sheet material separation assisting member comes into contact with the end of the laminated sheet material.
With the movement of the first linear motion member 3 and the second linear motion member 4, the sheet material 100 in which the sheet material separation assisting members 2 connected to the first linear motion member 3 and the second linear motion member 4 are laminated. The state which is approaching toward the edge of is shown.

  From the state of FIG. 1, the cylinder rod 51 a is extended by the operation of the cylinder 51 to linearly move toward the end of the sheet material 100 on which the first linear motion member 3 is laminated. At the same time, the cylinder rod 51 a is extended by the operation of the cylinder 52, thereby linearly moving toward the end of the sheet material 100 on which the second linear motion member 4 is laminated.

  A sheet in which the sheet material separation auxiliary member 2 connected to the first linear motion member 3 and the second linear motion member 4 is laminated in accordance with the movement of the first linear motion member 3 and the second linear motion member 4. Approach toward the end of the material 100.

  FIG. 2 shows a state in which the contact portion 21 of the sheet material separation assisting member 2 is in contact with the uppermost sheet material 101 which is one of the stacked sheet materials 100.

  The cylinder 51 and the cylinder 52 continue to operate, and the contact portion 21 continues to press the end of the uppermost sheet material 101. The reaction force generated when the contact portion 21 presses the end of the uppermost sheet material 101 causes an upward moment around the turning center C in the sheet material separation assisting member 2, and the sheet material separation assisting member 2 rotates. Start.

  Since the sheet material separation assisting member 2 starts to turn by the reaction force, it is not necessary to control the operation of the cylinders 51 and 52.

  By turning the sheet material separation assisting member 2, a gap can be generated in a part between the uppermost sheet material 101 and the sheet material in contact with the lower surface thereof. As the turning of the sheet material separation assisting member 2 progresses, the gap is expanded to the entirety between the uppermost sheet material 101 and the sheet material in contact with the lower surface thereof.

  FIG. 3 shows a state where the sheet material separation assisting member 2 is turning while the contact portion 21 is in contact with the uppermost sheet material 101.

  The cylinder 51 and the cylinder 52 continue to operate. In particular, the second linear motion member 4 is pushed toward the end of the uppermost sheet material 101 by the operation of the cylinder 52. The second linear motion member 4 further pushes the guide protrusion 22 of the sheet material separation assisting member 2 toward the end of the uppermost sheet material 101, so that the contact portion 21 of the sheet material separation assisting member 2 is the uppermost part. The sheet material 101 is pushed toward the end.

  Also by the operation of the cylinder 51, the second linear motion member 4 is pushed toward the end of the uppermost sheet material 101, and the sheet material separation assisting member 2 is moved to the uppermost sheet material via the curved guide 31 and the block 32. The contact portion 21 of the sheet material separation assisting member 2 is pressed toward the end of the uppermost sheet material 101.

  As a result, the contact portion 21 is pressed toward the end of the uppermost sheet material 101 even while the sheet material separation assisting member 2 is turning. By pressing the contact portion 21, the sheet material separation assisting member 2 can stably lift the uppermost sheet material 101 without being separated from the end of the uppermost sheet material 101 even during turning.

  FIG. 4 shows a state where the turning of the sheet material separation assisting member 2 is finished and the uppermost sheet material 101 is lifted and separated.

  In the sheet material separation assisting device 1, as shown in FIG. 1, the sheet material separation assisting member 2 approaches from a position away from the end of the stacked sheet material 100 in the Y-axis direction, and as shown in FIG. After coming into contact with the upper sheet material 101, the sheet material separation assisting member 2 starts to turn.

  Therefore, the uppermost sheet material 101 can be separated even if the positional accuracy of the arrangement of the stacked sheet materials 100 in the Y-axis direction and the end surface accuracy of the sheet material are low.

  Further, by extending the strokes of the cylinder rods 51a and 52a of the cylinders 51 and 52, the uppermost sheet material 101 can be separated even from a position away from the end of the stacked sheet material 100 in the Y-axis direction.

  As shown in FIG. 5, the sheet material 102 may be lifted with the sheet material 102 attached to the lower surface of the uppermost sheet material 101. Even in such a case, the uppermost sheet material 101 can be curved by the contact portion 21 pushing the uppermost sheet material 101 further. By curving the uppermost sheet material 101, a gap can be generated between the uppermost sheet material 101 and the sheet material 102 attached thereto.

  When this gap expands the gap between the uppermost sheet material 101 and the sheet material 102 in contact with the lower surface, the sheet material 102 falls and the uppermost sheet material as shown in FIG. 101 is reliably separated.

  FIG. 6 shows a state in which the sheet material separation assisting member 2 is swiveling while the end of the uppermost sheet material 101 is in contact with the lower end of the contact portion 21 of the sheet material separation assisting member 2.

  FIG. 7 shows a state in which the sheet material separation assisting member 2 is turning while the end of the uppermost sheet material 101 is in contact with the vicinity of the upper end of the contact portion 21 of the sheet material separation assisting member 2.

  The sheet material separation assisting device 1 is located at a position where the turning center C is below the lower end of the contact portion 21 and away from the end of the sheet material 100 laminated from the contact portion 21. Therefore, as shown in FIGS. 6 and 7, no matter which position of the uppermost sheet material 101 abuts on any position in the X-axis direction of the abutting portion 21, the abutting portion 21 is not in the uppermost sheet material 101. A reaction force is generated by pressing the end.

  By this reaction force, an upward moment is generated around the turning center C in the sheet material separation auxiliary member 2, and the sheet material separation auxiliary member 2 starts to turn. By turning the sheet material separation assisting member 2, a gap can be generated in a part between the uppermost sheet material 101 and the sheet material in contact with the lower surface thereof.

  Therefore, even if the positional accuracy in the X-axis direction of the arrangement of the stacked sheet materials 100 is poor, the uppermost sheet material 101 can be separated. Further, even if the height of the stacked sheet material 100 varies as the conveyance progresses, the variation in the height is within a range in which the contact portion 21 can contact the end of the stacked sheet material 100. If there is, the uppermost sheet material 101 can be separated without requiring raising / lowering of the laminated sheet material 100 or raising / lowering the entire sheet material separation auxiliary device 1.

  Further, as shown in FIG. 8, the sheet material separation assisting device 1 of the present embodiment can be arranged on both sides of the sheet material with respect to the sheet material stacked in a state greatly deviated in the Y-axis direction. For example, the sheet material separation auxiliary device 1 on the right side in the drawing contacts and lifts the end of the sheet material one sheet below the uppermost sheet material 101, and then the sheet material separation auxiliary device 1 on the right side in the drawing shows the uppermost portion. The sheet material 101 is lifted in contact with the end portion. As a result, even if the sheet material is laminated in a state greatly deviated in the Y-axis direction, a gap is generated in a part between the uppermost sheet material 101 and the sheet material in contact with the lower surface thereof. be able to.

  In the above embodiment, the sheet material separation assisting apparatus 1 has been described with respect to the case where the gap between the uppermost sheet material 101 and the sheet material in contact with the lower surface is enlarged. Instead, the sheet material separation assisting apparatus 1 may only generate a gap in a part between the uppermost sheet material 101 and the sheet material in contact with the lower surface thereof.

  The uppermost uppermost sheet material 101 and its lower surface are formed by blowing air into the gap generated by the sheet material separation assisting device 1 or raising the vacuum cup adsorbed on the upper surface of the uppermost sheet material 101. The uppermost sheet material 101 can be completely separated from the lower sheet material by expanding the gap between the sheet material and the sheet material in contact with the sheet material.

  In the above embodiment, the case where the laminated sheet material is made of, for example, a nonmagnetic metal such as aluminum or the like has been described. However, the sheet material is not limited thereto, and the sheet material may be a magnetic metal, resin, or paper. It may be made of non-metal such as.

  In the above-described embodiment, the case where the contact portion 21 has a saw blade shape has been described. However, the present invention is not limited to this, and the sheet is being swung between the end of the sheet material with which the contact portion contacts. It is only necessary to generate a frictional force that does not cause the material to fall.
