And a casing 2 having an accommodating portion 3 in which the laminated body 10 can be accommodated and for removing chips adhering to the cut portion and the vicinity thereof. ing.
Although not particularly illustrated, the laminate 10 may be tied with a string or the like as necessary.

  The accommodating portion 3 is formed so as to surround the side surface of the accommodated laminated body 10 from four directions by four inner side surfaces provided with a suction port for suction or a vent port serving as a blow-in port for blowing air. Has been. And the 1st blower 4a is connected to each ventilation port provided in the two inner surface which the accommodating part 3 opposes via the duct hose 5a, and each provided in the remaining two inner surfaces. A second blower 4b is connected to the vent via a duct hose 5b.

  The housing 2 provided in the chip removing device 1 shown in FIG. 1 has four quadrangular pyramid-shaped hollow members 2a. Each hollow member 2a is assembled so that the bottom surfaces of adjacent hollow members 2a are orthogonal to each other, and the accommodating portion 3 is formed in a space surrounded by these hollow members 2a. A hinge-type lid 6 that can close the housing 3 is attached to the housing 2.

  In addition, a bottom plate (not shown) is provided at the bottom of the accommodating portion 3. The casing 2 may be installed on a gantry as necessary, and the first blower 4a and the second blower 4b may be accommodated below the gantry. 3 may be the bottom.

In the housing 2 assembled in this way, a member having a large number of holes called punching metal or a wire mesh member is attached to the opening on the bottom side of each hollow member 2a. The inner side surface surrounding the side surface of the accommodated laminated body 10 from four directions is formed by such a member. And each hole or each mesh | network of the member which forms this inner surface becomes the vent provided in the said inner surface.
In addition, duct hose 5a, 5b which connects the 1st blower 4a and the 2nd blower 4b to each ventilation port is attached to the top part side of each hollow member 2a so that it may show in figure.

  According to such a chip removing device 1, chips generated when a sheet-like material is cut into a predetermined shape can be efficiently removed as follows.

  First, the laminated body 10 is accommodated in the accommodating portion 3, the lid body 6 is closed, and the accommodating portion 3 is closed. Next, the first blower 4a and the second blower 4b are driven to suck the inside of the closed accommodating portion 3. As a result, each side surface of the laminated body 10 is sucked from four directions surrounding the side surface of the laminated body 10, and chips attached to the cut portions of the stacked materials 10a and the vicinity thereof can be efficiently removed. .

  At this time, the timing of sucking each side surface of the laminated body 10 from the four directions surrounding the side surface of the laminated body 10 may be arbitrarily shifted, and the first blower 4a and the second blower 4b You may make it attract simultaneously from four directions surrounding a side surface.

In addition, by alternately performing suction and blowing with the first blower 4a and the second blower 4b, two opposing directions among the four directions surrounding the side surface of the laminate 10 and the remaining two Suction and blowing may be alternately performed depending on the direction.
That is, the air is sucked by the first blower 4a and simultaneously the air is blown by the second blower 4b, and the first blower 4a is switched to air blowing after a predetermined time has elapsed, and the second blower 4b is switched to suction. . There is no limit to the number of times such switching is performed, but when attention is paid to one side surface of the laminated body 10, suction is performed at least once after the first blow is performed on the side surface. It is preferable to do this. Further, the strength of suction or blowing by the first blower 4a and the second blower 4b can be appropriately adjusted so that the removal of chips can be efficiently performed, and the strength gradually changes. Also good.

  If suction is simultaneously performed from the four directions surrounding the side surface of the laminated body 10, it is conceivable that the inside of the housing portion 3 becomes a negative pressure state and suction efficiency decreases. On the other hand, if suction and air blowing are performed alternately, such a problem can be effectively avoided. Furthermore, if the suction and the blowing are alternately performed, the chips scattered by the blowing are sucked, and the chips attached to the cutting portion of each material 10a and the vicinity thereof can be more efficiently removed. It becomes possible.

  At this time, it is possible to prevent the chips from splashing out of the housing portion 3 when the housing portion 3 can be closed. It is not necessary to make the inside of the housing part 3 airtight as long as the chips are not scattered outside the housing part 3. In the example shown in FIG. 1, an example in which a hinge-type lid 6 is attached is shown. However, the lid 6 may be a slide type or a take-up type shutter.

[ Reference form ]
Next, a reference embodiment of the present invention will be described.
In addition, FIG. 2 is explanatory drawing which shows the outline of the chip removal apparatus which concerns on this reference form .

  As in the first embodiment, the chip removing device 1 shown in FIG. 2 is formed from a laminated body 10 in which sheet-like materials 10a cut and arranged in a predetermined shape are stacked so that the cut portions are arranged on the side surfaces. In order to remove the chips adhering to the cut portion and the vicinity thereof, a transport unit 7 for transporting the laminated body 10 is provided.

  In the example illustrated in FIG. 2, the transport unit 7 includes a first transport unit 7 a installed on the upstream side in the transport direction and a second transport unit 7 b installed on the downstream side. And between the 1st conveyance part 7a and the 2nd conveyance part 7b, the rotation mechanism 9 for rotating the laminated body 10 1/4 in the middle of conveyance is installed.

  As the transport unit 7, appropriate means such as a belt conveyor can be used in addition to the roller conveyor as illustrated. Further, the rotating mechanism 9 is not particularly limited as long as the laminated body 10 can be rotated by ¼, and an appropriate means such as a turntable can be used.

  Further, each of the first transport unit 7a and the second transport unit 7b has a suction port provided on both side edges of the transport units 7a and 7b and a blower (not shown) connected to the vent port. Mechanisms 8a and 8b are provided. Here, the suction mechanism 8a provided in the first transport unit 7a is a first suction mechanism, and the suction mechanism 8b provided in the second transport unit 7b is a second suction mechanism.

  As shown in the drawing, the first suction mechanism 8a and the second suction mechanism 8b each have a pair of square pyramid-shaped hollow members 80, and the hollow members 80 of the suction mechanisms 8a and 8b are respectively Are attached to both side edges of each of the transport parts 7a and 7b so that the bottom sides of the two face each other. A member having a large number of holes called punching metal or a wire mesh member is attached to the opening on the bottom surface side of each hollow member 80. Each mesh is designed to be a vent port standing on both side edges of the transport portions 7a and 7b.

  A duct hose 5 is attached to the top side of each hollow member 80. And the said vent is connected to the blower which is not shown in figure through the said duct hose 5, and the suction or ventilation from the said vent by the blower is possible.

  When the hollow member 80 is attached to both side edges of each of the transport portions 7a and 7b, the hollow member 80 is preferably attached so as to be movable in a direction orthogonal to the transport direction of the laminate 10. If it does in this way, according to the magnitude | size of the laminated body 10, the separation distance of the vent hole standingly arranged by the both-sides edge of the conveyance parts 7a and 7b can be adjusted. Thereby, when sucking the side surface of the laminated body 10 as will be described later, the suction port can be brought close to the laminated body 10 to increase the suction efficiency.

  According to such a chip removing device 1, chips generated when a sheet-like material is cut into a predetermined shape can be efficiently removed as follows.

  First, the stacked body 10 is supplied to the first transport unit 7a, and transported to the first suction mechanism 8a so that the opposing side surfaces of the stacked body 10 are parallel to the transport direction. And the blower of the 1st suction mechanism 8a is driven, and the two opposing side surfaces of the laminated body 10 are attracted | sucked from the vent hole standingly arranged by the both edge sides of the 1st conveyance part 7a.

When the suction by the first suction mechanism 8a is completed, the laminated body 10 is rotated by a quarter of a rotation by the rotation mechanism 9 and then transported to the second suction mechanism 8b by the second transport unit 7b. And the blower of the 2nd suction mechanism 8b is driven, and the remaining two surfaces of the laminated body 10 are sucked from the vents erected on both edge sides of the second transport portion 7b.
The laminated body 10 that has been sucked by the second suction mechanism 8b is carried out by the second transport unit 7b.

  By doing as above, each side surface of the laminated body 10 is sequentially sucked, which is equivalent to sucking from four directions surrounding the side surface of the laminated body 10. As a result, similarly to the first embodiment described above, chips attached to the cut portions of the stacked materials 10a and the vicinity thereof can be efficiently removed.

  Although the present invention has been described with reference to the preferred embodiment, it is needless to say that the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. .

For example, in the first embodiment described above, the first blower 4a is connected to the respective vent holes provided on the two opposing inner side surfaces of the accommodating portion 3 and provided on the remaining two inner side surfaces of the accommodating portion 3. Although the example in which the second blower 4b is connected to each vent is shown, the blower may be connected to each of the vents provided on each inner surface of the accommodating portion 3 on a one-to-one basis.
In the case where suction is simultaneously performed from four directions surrounding the side surface of the laminated body 10, one blower may be connected to the air vent provided on each side surface of the housing portion 3.

  Moreover, in 1st embodiment mentioned above, although the example which attracts | sucks or blows from four directions surrounding the side surface of the laminated body 10 was shown, in addition to the said four directions, from the up-down direction of the laminated body 10, or any one thereof May also be sucked or blown.

Moreover, also in the reference form mentioned above, it is also possible to remove chips by combining blowing and suction as in the first embodiment. In this case, it is preferable that the first suction mechanism 8a and the second suction mechanism 8b, which blow air, can block between the facing vents so that chips do not scatter during blowing. In this case, for example, as shown in FIG. 3, a lid 81 having a U-shaped cross section formed in a bellows shape so that it can expand and contract as the hollow member 80 moves is supported by the hollow member 80. What is necessary is just to attach to the made support | pillar 82 so that a vertical movement is possible. Thereby, when the laminated body 10 reaches | attains suction mechanism 8a, 8b, it can block | close between the vents which face by moving the said cover body 81 downward.

  INDUSTRIAL APPLICABILITY The present invention can be used in various technical fields in order to remove chips generated when cutting various sheet-shaped materials into a predetermined shape.
