b and.

In order to vertically separate the laminated body 3 by the separating device 6, first, the first placing device 15 moves the laminated body 3 up and down to receive the height of the vertically separated position of the laminated body 3 to receive the blade 3.
The height of the cutting edge 30a of 0 is matched.

Next, as shown in FIG. 8 (I), the traveling conveyor 17 is moved rearward, and the receiving blade 30 is arranged to the right of the front end of the laminated body 3. Further, the receiving member 48 is moved forward by the cylinder 46, and the rear side surface of the laminated body 3 is received by the receiving member 48. At this time, the lower end of the receiving member 48 is located below the vertically separated position of the laminated body 3. When the receiving member 48 receives the rear side surface of the laminated body 3, the limit switch 50 contacts the rear side surface of the laminated body 3 and sends a signal to the control device (not shown) of the cylinder 46, which causes , Cylinder 46 is deactivated,
The receiving member 48 prevents the stack 3 from being pushed forward.

Next, as shown in FIG. 8 (II), the receiving blade 30 is moved to the left by the cylinder 28 so that the laminated body 3 is formed.
Insert the receiving blade 30 into the
The blade 30 supports the upper side of the stack 3 above and below the separation position. The blade edge 30a of the receiving blade 30 inserted into the laminated body 3 elastically slightly oscillates downward due to the weight of the laminated body 3, and is located between the upper and lower surfaces of the main body of the receiving blade 30. This prevents the sheet material 1 from being scratched by the cutting edge 30a.

Next, the pallet 20 on which the laminated body 3 is placed is moved downward by the first placing device 15 and the rear side of the laminated body 3 is moved downward together with the pallet 20 so that the front end of the laminated body 3 is vertically separated. The lower side is moved downward together with the pallet 20. Thereby, the front end portion of the laminated body 3 which is located on the upper side after being divided into two parts is
It is in a state of being relatively lifted upward with respect to the laminated body 3 positioned on the lower side.

Next, as shown in (III) of FIG. 9, the cylinder 32 is extended to feed the rotor 35 between the upper and lower separations of the laminated body 3, and then, as shown in (IV) of FIG.
The traveling conveyor 17 is moved rearward so that the conveyor belt 2
6 is fed between the upper and lower layers of the laminate 3. As a result, the rear side in the delivery direction of the laminated body 3, which is located on the upper side, rides on the conveyor belt 26 to divide the laminated body 3 into upper and lower parts, and the laminated body 3 located on the upper side is mounted on the upper surface of the conveyor belt 26. Placed. At this time, since the rear side surface of the laminated body 3 located on the upper side is supported by the receiving member 48, when the longitudinal dimension of the laminated body 3 is short or the sheet material 1 has a small flexibility. Even in this case, it is possible to prevent the conveyor belt 26 from pushing the laminated body 3 located on the upper side backward. The height of the upper surface of the conveyor belt 26 is slightly lowered at the rear end,
The conveyor belt 26 is prevented from interfering with the receiving member 48. In addition, the fluid pressure cylinder 57 of the holding device 14
The expandable rod is moved downward, and the elastic force of the spring built into the pressing tool 59 acts on the upper surface of the front side of the laminated body 3 via the pressing body 59b. 3 is prevented from being pushed backward by the conveyor belt 26. Furthermore, the traveling conveyor 1
7, the rotor 35 is rotated and the conveyor belt 26 is driven to rotate, and the traveling conveyor 17
Of the rotor 35 and the rotational speed of the conveyor belt 26 are synchronized with each other to reduce the friction of the contact portion between the rotor 35 and the conveyor belt 26 with respect to the lower surface of the laminate 3 located on the upper side. The stacking of the laminated body 3 on the conveyor belt 26 is promoted. This makes it possible to surely divide the laminated body 3 into upper and lower parts and place the laminated body 3 located on the upper side on the conveyor belt 26, thereby preventing the laminated body 3 from collapsing.

Next, as shown in FIG. 10, the tilting fluid pressure cylinder 37 is extended, and its telescopic rod is attached to the rail 18.
By pushing the conveyor belt 26 to the front end of the traveling conveyor 17 above the rear end of the conveyor belt 26,
The height of the front end of the conveyor belt 26 is matched with the upper surface of the air table 16. Then, the conveyor belt 26 is driven to rotate, so that the laminated body 3 placed on the conveyor belt 26 is placed on the air table 16 of the feeding device 7.

Next, the tilting fluid pressure cylinder 37 is contracted, the traveling conveyor 17 is moved forward and returned below the air table 16, and the receiving member 48 is moved to the fluid pressure cylinder 4.
By displacing the laminated body 3 backward by 6, the separation process of the laminated body 3 can be repeated. At this time, by displacing the receiving member 48 rearward by the fluid pressure cylinder 46, the receiving member 48 restricts the upward movement of the laminated body 3 when the laminated body 3 is moved upward by the first placement device 15. The sheet material 1 forming the laminated body 3 is not damaged.

In the separating device 6, the stack 3 is carried into the first placing device 15 from the rear of the receiving member 48. Therefore, the first placement device 1
When the stack 3 is loaded into the stack 5, the support plate 41 is moved in the left-right direction along the guide rod 40, so that the receiving member 48 is retracted to a position where it does not interfere with the stack 3 in the process of being loaded. Further, since the dimension of the laminated body 3 in the front-rear direction varies depending on the type of the sheet material 1, it is necessary to change the receiving position of the laminated body 3 by the receiving member 48 according to the change in the dimension. It is possible to deal with the change of the receiving position of the receiving member 48 by expanding and contracting the fluid pressure cylinder 46, but since the fluid pressure cylinder 46 becomes large, the fixing position of the fixing plate 49 with respect to the guide plate 45 is changed in the front-back direction. By doing so, the change in the receiving position is dealt with.

It should be noted that the means for relatively raising the laminated body located on the upper side to the laminated body located on the lower side on the front side in the feeding direction is not limited to the above-mentioned structure, and is well known in the art. The configuration can be used, and the sending-out body that sends out the stacked body is not limited to the conveyor belt, and for example, a transport table may be used, and the structure that sends the sending-out body between the divisions of the stacked body is not limited to the above mechanism. Further, the structure of the receiving member is not particularly limited as long as it can support the side surface on the rear side in the delivery direction of the laminated body, and the displacement means of the receiving member is particularly limited as long as it can be displaced along the delivery direction of the laminated body. Not done.

As shown in FIG. 7, the air table 16 has a large number of air outflow holes 60 which are open on the upper surface thereof. The air outflow hole 60 is opened and closed by a ball 62 that can be projected and retracted on the upper surface of the table body 61. That is, the ball 62 is pushed upward by the spring 64 to close the air outflow hole 60. The air outflow hole 60 is connected to a blower (not shown) via a pipe 63. When the laminated body 3 is placed on the table body 61, the balls 62 move to the laminated body 3
Is pushed down to open the air outflow hole 60, an air layer is formed between the lower surface of the laminated body 3 and the table body 61, and the lower surface of the sheet material 1 in the lowermost layer of the laminated body 3 and the upper surface of the table body 61. Friction between is reduced.

The pusher 65 is shown in FIGS.
As shown in 0, a moving body 67 supported by a guide 66 attached to the rail 56 so as to be movable in the front-rear direction, and a screw 69 that meshes with a nut 68 attached to the moving body 67 are rotationally driven. A motor 70,

A pair of left and right pusher main bodies 75 are attached via an L-shaped arm 74.

By rotating the screw 69, the pusher main body 75 moves in the front-back direction, and by expanding and contracting the fluid pressure cylinder 73, the pusher main body 75 moves in the vertical direction. When the stack 3 is fed onto the air table 16 by the separating device 6, the pusher main body 75 is arranged at the standby position behind the air table 16 and above the stack 3 as shown in FIG. The stack 3
When the air is sent from the air table 16 to the punching device 8, the pusher main body 75 is moved downward and then moved forward as shown in FIGS. 4 and 5, whereby the stack 3 on the air table 16 is pushed. The rear side surface is pushed by the main body 75 and is sent to the punching device 8. The pusher main body 75 may be attached to the arm 74 so as to be rotatable around the longitudinal axis, and the lower end of the pusher main body 75 may be vertically moved.

As shown in FIGS. 11 and 12, the punching device 8 includes a frame 80, a plurality of supporting members 81 for supporting the laminated body 3, and an upper surface of the laminated body 3 supported by the supporting members 81. The pressing mechanism 83 presses the upper die 82 at the outer position of the cut 2, and the push-up mechanism 85 pushes up the lower surface of the laminate 3 at the inner position of the cut 2 via the lower die 84.

A pair of front and rear support bars 86, 87 along the left-right direction are attached to the frame 80, and each support member 81 is detachably attached to the support bars 86, 87 from above via a bracket 81a. The position can be changed left and right, and for example, the support bar 8
6, 87 and the bracket 81a are fixed via pins that can be inserted and removed.

The pressing mechanism 83 is screwed to the upper die substrate 90 located above the support member 81, the vertical screw 91 attached to the upper die substrate 90, and the screw 91. A nut 92 is rotatably supported on the frame 80, and a transmission mechanism 94 that converts the rotation of the motor 93 into the rotation of the nut 92. The upper mold 82 is detachably attached to the upper mold substrate 90 via the upper mold base 95. This allows
By rotating the nut 92 by the motor 93, the upper mold 82 moves up and down.

The push-up mechanism 85 includes a lower die substrate 98 attached to the frame 80 below the support member 81 so as to be vertically movable via a guide 97, and a crank mechanism 99 attached to the lower die substrate 98. , A transmission mechanism 1 for transmitting the rotation of the motor 100 to the crank mechanism 99
01 and. The lower die 84 is detachably attached to the lower die substrate 98 via the lower die base 103. As a result, the lower die 84 moves up and down by driving the crank mechanism 99 with the motor 100.

The laminated body 3 is supported by the support member 81 of the punching device 8, and then the upper die 82 is lowered to hold the outer position of the cut 2 on the upper surface of the laminated body 3 and then the lower die 84. By pushing up the lower surface of the laminated body 3 at the inner position of the cut 2 by raising, the laminated sheet piece 5 can be punched from the laminated body 3.

The stack 3 is fed from the air table 16 onto the support member 81 of the punching device 8 by pushing the rear side surface of the stack 3 by the pusher body 75. At this time, if the lower end of the pusher body 75 is always brought into contact with the upper surface of the air table 16, the air table 16 and the pusher 65 are easily damaged and their life is shortened. Therefore, as shown in FIG. Between the upper surface 16a of the air table 16 and the upper surface 16a of the air table 16.
Is provided. It is difficult to make the gap δ smaller than the thickness of the sheet material 1 that forms the laminated body 3 because of the bending of the arm 74 that supports the pusher main body 75 and the assembly and processing tolerances. On the other hand, the lower surface 3 of the laminated body 3
The friction between a and the upper surface 16a of the air table 16 is smaller than the friction between the sheet materials 1 forming the laminate 3 due to the air layer formed therebetween, but the support member 81 of the punching device 8 is used. If the friction between the upper surface of and the lower surface of the laminated body 3 is reduced, the laminated body 3 moves due to inertia,
Since the position of the laminated body 3 with respect to the upper mold 82 and the lower mold 84 cannot be set to a fixed position, the friction is larger than the friction between the sheet materials 1. Therefore, when the laminated body 3 pushed by the pusher main body 75 reaches the support member 81 from above the air table 16, if the lowermost sheet material 1 of the laminated body 3 is not pushed by the pusher main body 75, The sheet material 1 of the lowermost layer is displaced from the upper sheet material 1 and causes a defective punching of the laminated sheet piece 5.
Therefore, a pair of prismatic riding members 106 and 107 that project upward from the upper surface of the air table 16 are provided.

As shown in FIGS. 14 and 15, the riding members 106 and 107 are attached to the front end of the air table 16 via a support mechanism 108. The support mechanism 108 includes a base plate 110 attached to the air table 16 via a bracket 109, a pair of front and rear rails 111 and 112 attached to the base plate 110 along the left-right direction, and the rails 111 and 11.
A pair of left and right moving plates 113 and 114 movably supported in the left and right direction by the base plate 11
A pair of blocks 115 attached to the left and right ends of 0,
And 116. Levers 117 and 118 are respectively inserted into the blocks 115 and 116 so as to be movable in the left-right direction, and bolts 119 and 120 that fix the movement of the levers 117 and 118 are releasable.
5, 116 are screwed together. Each lever 11
7 and 118, the moving plates 113 and 114, respectively.
Are connected. A pressing plate 12 is detachably attached to the upper part of each moving plate 113, 114 with a bolt 121.
2, 123 are attached and the pressing plate 12
The riding members 106 and 107 are sandwiched between the second and 123 and the moving plates 113 and 114. As a result, the position of each of the riding members 106 and 107 can be changed in the front-rear direction, the up-down direction, and the left-right direction.

The cross sections of the riding members 106 and 107 are quadrangular, and the rear end side is arranged on the upper surface of the air table 16, and the front end side is arranged laterally to the support member 81 of the punching device 8. In addition, both riding members 106, 107
Both pusher main bodies 75 are arranged between the left and right sides of the. The rear ends of the riding members 106 and 107 are guide portions 106a and 107a that are directed downward as they go rearward. As a result, the stacked body 3 pushed by the pusher main body 75 can ride on the riding members 106, 107 from the upper surface of the air table 16 via the guide portions 106a, 107a. This riding member 106, 10
As shown in FIG. 13, the riding of the laminated body 3 on the laminated body 7 causes the laminated body 3 to bend, and a gap D is formed between the lower surface 3 a of the laminated body 3 and the upper surface 16 a of the air table 16. The lower surface 3a of the laminated body 3 and the upper surface 16a of the air table 16
The gap D formed between the pusher body 75 and the pusher body 75 pushes the rear side surface of the laminate 3 at a position where
Is larger than the gap δ generated between the lower end of the air table 16 and the upper surface 16a of the air table 16.

As a result, the pusher main body 75 can reliably push the rear side surface of the sheet material 1 of the lowermost layer of the laminated body 3, so that the laminated body 3 is supported on the air table 16 from the support member 81.
When reaching the top, it is possible to prevent the sheet material 1 of the lowermost layer of the laminated body 3 from being displaced with respect to the upper sheet material 1, and to prevent punching failure of the laminated sheet piece 5. Further, it can be easily carried out only by attaching the riding members 106 and 107 to the air table 16. Note that the shape and mechanism of the pusher 65 are not particularly limited to the above configuration as long as it can push the side surface of the laminate 3. Further, the shape and dimensions of the riding member and the guide portion are not particularly limited as long as the above-described action is exhibited.

In the punching device 8, the laminated body 3
The lower die 84 before pushing up is disposed below the upper surface of the support member 81 so as not to interfere with the laminated body 3. The vertical distance between the upper surface of the lower mold 84 and the upper surface of the support member 81 before the push-up is made as small as possible in order to shorten the punching time and downsize the apparatus. In order to prevent the laminated body 3 which is bent and hung down between the supporting portions by the plurality of supporting members 81 from colliding with the lower die 84 before being pushed up while being fed from the air table 16, FIG.
As shown in FIG. 4 and FIG. 16, the sagging restricting member 124 of the laminated body 3 is provided between the air table 16 and the lower die 84.
