Description

The present invention relates to a carry-out guide device for guiding a cut sheet material cut on a brush surface in a cutting machine so as to prevent biting when carried out.

2. Description of the Related Art Conventionally, as a delivery guide device of this type of cutting machine, there is known a device that conveys a cutting sheet material cut on a brush surface between sprockets (see Patent Document 1).

Further, there is also one in which the cutting sheet material is conveyed while being cut on the brush surface (see Patent Document 2). With this, the cutting sheet material is conveyed on the brush surface in a suctioned state, and it is possible to cut a long cutting sheet material that exceeds the cutting area on the brush surface, which is advantageous in improving cutting efficiency. It will be

And in the thing of the said patent document 1, the comb provided with several nail|claw is provided in the conveyance direction downstream of a cutting machine, and this comb scoops up a cutting sheet material from a brush surface, and delivers it to a delivery surface. I am trying.

The root of each claw of such a comb is located on the downstream side in the transport direction with respect to the center of the sprocket on the downstream side in the transport direction. Therefore, the delivery surface is located further downstream than the comb in the transport direction, and the length of the cutting machine in the transport direction becomes long, resulting in an increase in size.

Therefore, by positioning the roots of the comb claws on the upstream side in the transport direction with respect to the center of the sprocket on the downstream side in the transport direction, the delivery surface can be brought closer to the brush surface to shorten the length of the cutting machine in the transport direction, thereby cutting. A device that is designed to be downsized has been proposed (see Patent Document 3).

Japanese Patent No. 2735805 Japanese Patent No. 5100369 JP, 2009-72886, A

By the way, if the root of each claw of the comb is located upstream of the center of the sprocket on the downstream side in the transport direction as in the above-mentioned proposal, it is necessary to position the delivery surface at a higher position than the brush surface. There is. This is because each block of bristle brushes that make up the brush surface and are arranged in the cutting machine conveyance direction rotates around the sprocket with both ends in the conveyance direction floating up and out of the sprocket. Because it comes into contact with. From this point, in order to avoid contact with the end of each block in the transport direction, it was necessary to position the delivery surface at a higher position than the brush surface.

Moreover, if the roots of the claws of the comb are located on the upstream side in the transport direction with respect to the center of the sprocket on the downstream side in the transport direction, when the cutting sheet material is transported in the suction state on the brush surface, the comb and The delivery surface is also likely to be affected by suction. At this time, if the roots of the nails of the comb are sucked up to the vicinity of the brush surface, the height difference between the roots of the nails and the brush surface may be blocked, and the cutting sheet material may be bitten in the meantime. This is also due to the shape of the cut cut sheet material, and tends to appear more conspicuously in the case of a sharp cut sheet material having a sharp tip cut toward the downstream side in the transport direction.

In addition, as the cutting sheet material, in addition to the cutting material (cutting parts) and the uncut material cut from the material sheet, an underlay paper sheet laid on the brush surface when the material sheet is placed is cut together with the material sheet. It includes cut paper, cut residual paper, and cut vinyl and cut residual vinyl cut together with a cloth sheet from a closed vinyl sheet that covers and seals a cloth sheet used by laminating a plurality of sheets.

Since the cutting sheet material with a sharp shape is easily drawn into the pitch of each claw, there is no escape space when it is drawn into the pitch of each claw due to the height difference between the base of each claw and the brush surface. Then, as soon as you are drawn into the pitch, you will be bitten and the rest will be involved. On the other hand, if the height difference between the base of each claw and the brush surface is secured, even a cutting sheet material with a sharp shape becomes a relief space when pulled into the pitch of each claw, and The part that remains without being pulled back is pulled back along with the conveyance.

The present invention has been made in view of the above point, and an object thereof is to ensure that the height difference between the base of each nail and the brush surface is ensured, and a cutting sheet material having a sharp shape. An object of the present invention is to provide a carry-out guide device for a cutting machine, which can effectively prevent the biting of the blade.

In order to achieve the above-mentioned object, in the present invention, a cutting sheet material that is cut on a brush surface and conveyed between sprockets in a suction state is provided at a position higher than the brush surface on the downstream side in the conveying direction. While scooping with a comb having a plurality of claws for delivery to the surface, the roots of the claws are located upstream of the center of the sprocket on the downstream side of the sprocket in the direction of transport of the cut sheet material. It is premised on the carry-out guide device of the positioned cutting machine. Then, a spacer is provided on the lower surface of at least one of the delivery surface and the comb so as to float the roots of the claws of the comb between the brush surface and the brush surface. It is characterized by that.

Further, the spacer is cut out from the upstream end in the transport direction of the cutting sheet material toward the downstream side in the transport direction so as to avoid contact with the brush surface on the brush surface side on the upstream side in the transport direction of the cutting sheet material. Notches may be provided.

Furthermore, the spacer may be formed in a strip shape that continuously extends in a width direction orthogonal to the transport direction of the cut sheet material.

As described above, by providing an intervening spacer in a state of contacting the brush surface so that the roots of the nails of the comb are floated between the brush surface and the lower surface of at least one of the delivery surface and the comb, The height difference between the base of each nail and the brush surface is reliably ensured. Therefore, when the cutting sheet material having a sharp shape is drawn into the pitch of each claw, the height difference between the base of each claw and the brush surface becomes an escape space, and the drawn cutting sheet material is not drawn into the pitch. The remaining portion is pulled back along with the transportation. As a result, it is possible to effectively prevent the cutting sheet material having a sharp shape from being bitten.

In addition, the spacer is provided with a cutout portion on the upstream brush surface side in the transport direction from the upstream end in the transport direction of the cut sheet material toward the downstream side in the transport direction so as to avoid contact with the brush surface. The contact surface with the brush surface is shifted to the downstream side in the conveying direction by the notch part, and the escape space for the cutting sheet material with a sharp shape can be expanded, and the biting of the cutting sheet material with a sharp shape can be prevented more effectively. be able to.

Further, the spacer is formed in a strip shape continuously extending in the width direction orthogonal to the conveying direction of the cut sheet material, so that the spacer is evenly contacted with the brush surface in the width direction, so that the brush surface is not worn or the sprocket is worn. It is possible to make the rotational load of the uniform in the width direction.

It is a vertical section side view of a cutting machine provided with a carrying-out guide device concerning an embodiment of the invention. FIG. 2 is a plan view of the vicinity of the carry-out guide device in FIG. 1. It is the enlarged view which expanded the comb vicinity of the carry-out side of the carry-out guide apparatus of FIG. It is explanatory drawing which shows the state which the cutting sheet material was sent near the comb by the side of the delivery of the delivery guide apparatus of FIG.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a vertical sectional side view of a cutting machine equipped with an unloading guide device according to an embodiment of the present invention, and FIG. 2 is a plan view of the unloading guide device shown in FIG.

1 and 2, the cutting machine 1 includes a cutting table 11 surrounded by a frame body 10 having a substantially rectangular frame shape. The cutting table 11 is composed of a conveyor 13 in which blocks 12 of bristle brushes 12, 12,... Are arranged in the longitudinal direction, and the surface is formed by the tips of the bristles of each block 12. The cloth sheet 14 is placed on the breathable underlayment sheet 15 laid on the brush surface 131 of the cutting table 11.

The cutting table 11 formed of bristles has air permeability, and is moved in the longitudinal direction of the frame body 10 in a state where the dough sheet 14 on the conveyor 13 is sucked and held by the suction chamber 16 provided on the upper side of the conveyor 13. Transport. At this time, since the cloth sheet 14 has air permeability, a plurality of sheets are used by being laminated, and by covering from above with a closed vinyl sheet 17 such as a synthetic resin film, the whole sheet can be sucked and held. ..

Further, the cutting machine 1 includes a cutting head 21 that moves along the surface of the cutting table 11. The cutting head 21 includes a cutting blade 22 that projects toward the cutting table 11 side (downward). The bristles of each block 12 are made of synthetic resin or the like, and when the cutting blade 22 enters from the surface of the cutting table 11, elastically deforms and escapes from the cutting edge. The mechanism for moving the cutting head 21 along the surface of the cutting table 11 is omitted.

A carry-in side table 23 is provided on the carry-in side of the cutting table 11 which is a part of the conveyor 13, and prepares the dough sheet 14 and introduces it onto the cutting table 11. A delivery-side table 24 as a delivery surface is provided on the delivery side of the cutting table 11, and is used when delivering the cutting sheet material S to a pickup table or the like provided on the downstream side. In this case, at the time of carrying-in and carrying-out work by operating the conveyor 4, an airflow is jetted from the surfaces of the carry-in side table 23 and the carry-out side table 24, and the cutting sheet material S is floated up and easily moved.

Inner end portions of the carry-in side table 23 and the carry-out side table 24, which face the cutting table 11, respectively, are formed from the centers of the sprockets 25, 26 on both sides of the cutting sheet material S in the conveying direction (shown by white arrows in FIG. 1). Are located on the inner side.

Further, the respective surfaces of the carry-in side table 23 and the carry-out side table 24 are located higher than the brush surface 131 of the cutting table 11. This prevents each block 12 constituting the brush surface 131 from contacting both ends in the transport direction that rotate while rotating around the sprockets 25 and 26 while floating around the sprockets 25 and 26. Therefore, it is necessary to position the carry-in side table 23 and the carry-out side table 24 at a position higher than the brush surface 131.

A carry-in guide device 31 and a carry-out guide device 32 are provided at inner ends of the carry-in side table 23 and the carry-out side table 24. The carry-in guide device 31 and the carry-out guide device 32 are provided with combs 33 and 34 having slopes on their surfaces so that the cutting sheet material S can be moved smoothly even if there is a difference in height between the carry-in guide device 31 and the carry-out guide device 32. The base ends of the combs 33, 34 are connected to the inner ends of the carry-in side table 23 and the carry-out side table 24. A plurality of comb-teeth-shaped claws 35, 35,... Projecting from the base portion 30 (only the one on the unloading side table 24 side) is provided on each of the combs 33, 34 in the width direction orthogonal to the conveying direction of the cutting sheet material S Are provided at equal pitch.

FIG. 3 is an enlarged view of the vicinity of the discharge side comb 34 of the discharge guide device 32 of FIG. 1, and FIG. 4 shows the cut sheet material S sent to the vicinity of the discharge side comb 34 of the discharge guide device 32 of FIG. The explanatory views showing the states are respectively shown.

As shown in FIGS. 3 and 4, each claw 35 of the comb 34 of the carry-out guide device 32 projects toward the upstream side in the transport direction of the cut sheet material S, and the tip end thereof is located in the bristles of each block 12. Inclined downward to enter. The roots of the claws 35 of the comb 34 of the carry-out guide device 32 are located on the upstream side in the transport direction with respect to the center of the sprocket 26 on the downstream side in the transport direction of the cut sheet material S.

At the lower end of each block 12, a plurality of shafts 41, 41,... Extending in the width direction of the cut sheet material S are rotatably supported. A plurality of rollers 42 are rotatably connected to each shaft 41, and a cylindrical member 43 having a smaller diameter than the rollers 42 is rotatably supported between the rollers 42 adjacent to each other in the width direction. Has been done.

Each sprocket 25, 26 is provided with a substantially semi-circular engagement portion 27, 27,... Recessed to engage with the cylindrical member 43 of each block 12 in a disengageable manner. Then, the conveyor 13 is driven by driving one sprocket 25 of each sprocket 25, 26 so that the cylindrical member 43 of each block 12 wound between both sprockets 25, 26 is sequentially engaged and disengaged and conveyed. I am trying. Further, among the blocks 12, in each block 12 in the upper part where the tips of the bristles form the surface of the cutting table 11, the rollers 42 roll on the rails 28 extending substantially horizontally in the transport direction. The surface of the cutting table 11 (tips of the bristles of each block 12 on the upper side portion) is made substantially horizontal.

The spacer 5, which is interposed in contact with the brush surface 131 so as to float the root of each claw 35 of the comb 34 between the brush surface 131 and the inner side of the carry-out side table 24 from the root of each claw 35 of the comb 34. It is attached to the lower surface of the corresponding portion A that extends to the side edge. At this time, the spacer 5 only needs to be provided on the lower surface of at least one of the carry-out side table 24 and the carry-out side comb 34, and the roots of the claws 35 of the carry-out side comb 34 serve as the brush surface 131. It suffices that the brush surface 131 is interposed so as to be floated between the brush surfaces 131.

Further, the spacer 5 is linear on the brush surface 131 side on the upstream side of the cutting sheet material S in the conveying direction from the upstream end in the conveying direction of the cutting sheet material S toward the downstream side in the conveying direction so as to avoid contact with the brush surface 131. A cutout portion 50 is formed by cutting out a slope 51 that extends obliquely downward. Further, the spacer 5 is formed in a strip shape that continuously extends in the width direction (in FIG. 3, the front side and the rear side in the drawing) orthogonal to the transport direction of the cut sheet material S. The spacer 5 is set to have substantially the same width as the width of the comb 34.

Reference numeral 141 in FIG. 4 is a cutting material (cutting part) of the cutting sheet material S cut from the material sheet 14, and reference numeral 142 is a cutting residual material. Further, reference numeral 143 denotes a sharp-shaped projection piece of the cutting residual material 142, which has a tip that is sharpened toward the downstream side in the transport direction, and is on the extension line X of each of the projection pieces 143. FIG. 4 shows a state in which the pitch of each claw 35 of the comb 34 is positioned. At this time, it is also effective to make the pitch of each claw 35 as narrow as possible to make it difficult for the protrusion 143 to be pulled in.

Therefore, in the present embodiment, the spacer 5 interposed in contact with the brush surface 131 so that the base of each claw 35 of the comb 34 floats between the brush surface 131 and the base of each claw 35 of the comb 34 is disposed. Since it is attached to the lower surface of the corresponding portion A extending from the inner side end portion of the carry-out side table 24, even if the base of each claw 35 is sucked, the height difference from the brush surface 131 is reliably ensured. By ensuring the height difference, a clearance space is formed between the lower surface of each claw 35 and the brush surface 131, and even if the projection piece 143 is pulled into the pitch of each claw 35, the tip of the projection piece 143 is a clearance space. If it is inside, biting does not occur. Further, the cutting residual material 142 that is not drawn into the pitch and is pulled up to a high position along the inclined surface formed by the upper surfaces of the claws 35, the projection piece 143 is pulled back from within the pitch. Thereby, it is possible to effectively prevent the protrusion piece 143 of the cutting sheet material S having a sharp shape from being bitten.

Further, since the spacer 5 is provided with the cutout portion 50 that is cut out by the slope 51 that linearly extends obliquely downward from the upstream end in the transport direction of the cut sheet material S toward the downstream side in the transport direction, the spacer 5 is provided. By the notch 50, the contact surface of the cutting table 11 with the brush surface 131 is shifted to the downstream side in the transport direction, so that the relief space of the projection piece 143 having the sharp cutting residual fabric 142 can be expanded, and the projection piece 143 can be bitten. Can be prevented more effectively.

Further, the spacer 5 is formed in a strip shape in which the lower surface of the corresponding portion A extending from the root of each claw 35 of the comb 34 to the inner end of the carry-out table 24 continuously extends in the width direction orthogonal to the transport direction. Therefore, the spacer 5 can be brought into uniform contact with the brush surface 131 of the cutting table 11 in the width direction, and the wear of the brush surface 131 and the rotational load of the sprockets 25, 26 can be made uniform in the width direction.

It should be noted that the present invention is not limited to the above-described embodiment, and includes various other modified examples. For example, in the above-described embodiment, the spacer 5 is formed in a strip shape that continuously extends in the width direction of the cutting sheet material S, but the spacer may not extend continuously in the width direction of the cutting sheet material, and a plurality of spacers may be formed. The spacers may be arranged intermittently in the width direction with a slight gap. Further, the shape of the plurality of spacers is not limited to the block shape obtained by dividing a strip, and may be a dish shape such as a circular shape or an elliptical shape.

Further, in the above-described embodiment, the spacer 5 is attached to the lower surface of the corresponding portion A extending from the root of each claw 35 of the comb 34 to the inner end of the carry-out side table 24. It may be provided integrally with the root or the inner end of the unloading-side table, or integrally with both.

Further, in the above-described embodiment, the spacer 5 is provided with the notch portion 50 which is notched by the slope 51 that linearly extends obliquely downward, but from the upstream end in the transport direction of the cut sheet material toward the downstream side in the transport direction. The cutout may be a cutout formed by a curved surface that curves in an obliquely downward direction while drawing an arc, or a cutout part that is cut out in a stepwise manner in the obliquely downward direction. Further, the spacer 5 may not be provided with the cutout portion.

Furthermore, in the above-described embodiment, a plurality of breathable fabric sheets 14 are used by stacking, but the number of fabric sheets may be one, and in the case of non-breathable leather or resin, a closed vinyl sheet is used. It does not have to be used.

Moreover, in the said embodiment, although the case where the sharp-shaped protrusion piece 143 of the cutting residual material 142 cut from the cutting sheet material S bites was described, among the cutting materials cut from the cutting sheet material, Needless to say, the same effect can be obtained in the case of a projection piece having a sharp shape whose tip is pointed toward the downstream side in the conveyance direction.
