  Hereinafter, in FIGS. 1 to 3, 4, 5, 6, and 7, the discharge guide devices 10, 20, and 30 of the cutting machine 1 as the first, second, and third embodiments of the present invention are described. The configuration and operation are shown respectively. However, in the plan views of FIGS. 2, 5, and 7, the width direction of the cutting table 2, which is the vertical direction of the drawings, is shown in a state where the intermediate portion is omitted and the whole is shortened.

  In addition, in order to simplify the description, portions that are not described in the drawings to be described may be referred to with reference numerals described in other drawings. Moreover, in each figure, the same reference numeral is given to a common part, and a description overlapping with the preceding description may be omitted, including a description regarding the background art.

  FIG. 1 shows, as a front view, a schematic configuration of a discharge guide device 10 of a cutting machine 1 as Embodiment 1 of the present invention. The cutting machine 1 includes a cutting table 2. Although not shown, the cutting machine 1 is also provided with a cutting head provided with a cutting blade, a fabric presser and the like. The cutting table 2 also has a function as the transport conveyor 3. As the cutting head moves along the surface of the cutting table 2, the cutting blade cuts the sheet material 4 sucked and held on the cutting table 2 in accordance with preset cutting data.

  The material to be cut 4 a cut from the sheet material 4 is conveyed to the carry-out side on the left side of the drawing by the conveyer 3 and is discharged onto the upper surface of the carry-out table 6. The conveying conveyor 3 is formed by arranging bristle brushes 5 which are plastic molded products so as to have air permeability. The transfer conveyor 3 is stretched around a sprocket wheel (not shown) at both ends in the transfer direction. When the block-like bristle brush 5 passes through the sprocket wheel while rotating, a part of the locus becomes higher than the surface of the cutting table 2 formed by the tip of the bristle brush 5 between the sprocket wheels. Since the carry-out table 6 needs to retract the locus of the bristle brush 5 when covering the end of the conveyor 3, the upper surface of the carry-out table 6 is at a higher position than the surface of the cutting table 2. The comb 7 is provided so that the to-be-cut material 4a may move smoothly in this level | step-difference part. In the comb 7, a plurality of claws 7 a are juxtaposed and protruded from the carry-out table 6 to the surface side of the conveyor 3. The upper edge of the claw 7 a becomes a part of a slope that extends from the surface of the cutting table 2 to the upper surface of the carry-out table 6. The lower part of the claw 7 a is divided into the bristles of the bristle brush 5.

  On the carry-out side of the cutting machine 1, a pick-up conveyor 8 for performing the work of taking out the material to be cut 4 a is arranged following the carry-out table 6. The pick-up conveyor 8 can convey the material to be cut 4a on the upper surface of the conveyor 8a. A gear 8b for taking out the rotation output for conveyance is attached to the shaft end of the end portion of the conveyor 8a on the cutting machine 1 side.

  The discharge guide device 10 of the present embodiment includes a conveyor 11 which is a passage guide means. In the conveyor 11, the endless belt 12 is driven so as to circulate around a plurality of rollers 13a, 13b, 13c, 13d, and 13e. In the following description, the plurality of rollers 13a, 13b, 13c, 13d, and 13e may be collectively referred to as the roller 13. The rollers 13a, 13b, 13c, 13d, and 13e are attached to the frame 14. The lower surface of the belt 12 covers a range including the slope of the comb 7 and the carry-out table 6 including at least a portion that transitions from the slope of the comb 7 with an interval smaller than the thickness of the two layers of the material 4a to be cut from above. . The conveyor 11 guides the interval so that the material to be cut 4a passes in the carry-out direction from the comb 7 toward the carry-out table 6.

  The rollers 13c and 13d are supported at the free ends 15aa and 15ba of the swing arms 15a and 15b at both ends of the rotation shaft, respectively. Between the rollers 13c and 13d, the lower surface of the belt 12 is brought into contact with the upper surface of the carry-out table 6 to support the weight of the conveyor 11. Since the base ends 15ab and 15bb of the swing arms 15a and 15b are supported by the outer frame member 15 in a swingable state, the rollers 13c and 13d can be displaced with respect to the frame 14. The clearance between the rollers 13a and 13b and the slope of the comb 7 can be adjusted by adjusting the swinging state of the swinging arm 15a.

  Even if the lower surface of the belt 12 and the slope of the comb 7 or the upper surface of the carry-out table 6 come into contact with each other or a portion having a small interval is generated, the interval between the cut material 4a and the cut material 4a passes. Pushed up by one layer or more and allowed to pass. If the distance at which the material to be cut 4a passes is smaller than the thickness of two layers, the material to be cut 4a rises even at the step portion between the surface of the cutting table 2 and the upper surface of the carry-out table 6. It passes without overlapping and is discharged stably without stagnation.

  The frame 14 is formed by combining an outer frame member 15 disposed on both sides in the width direction and an inner frame member 16 extending between the outer frame members 15. The end of the frame 14 on the pickup conveyor 8 side is supported by a support member 17 attached to the frame 8c of the pickup conveyor 8 so as to be swingable. A handle 14a extending outward in the width direction is attached near the tip of the outer frame member 15 on the comb 7 side, and the conveyor 11 can be opened manually by operating the handle 14a. The support member 17 supports the conveyor 11 at both ends of the shaft 14b of the roller 13e. A gear 14c that meshes with the gear 8b of the pickup conveyor 8 is attached to the shaft 14b of the roller 13e, and drives the roller 13e. Since the belt 12 is stretched between the roller 13e on the pickup conveyor 8 side and the roller 13a on the comb 7 side, the belt 12 is driven around the roller 13e. That is, the shaft 14b serves as a portion that receives driving from the pickup conveyor 8 side, and serves as a rocking base end with the comb 7 side as a free end.

  Both ends of the shaft 14b are supported by the support plate 15c in a rotatable state. A long hole is provided in the mounting portion on the outer frame member 15 side that is supported by the support plate 15c, and the position of the portion on the comb 7 side of the conveyor 11 and the tension of the belt 12 can be adjusted with respect to the roller 13e. .

  The conveyor 11 can be driven by providing an independent drive source as the discharge guide device 10. Alternatively, the driving force can be transmitted from the conveyor 3 of the cutting machine 1. In this embodiment, the conveyor 11 is driven from the pickup conveyor 8 side, and the workpiece 4 a can be smoothly moved to the pickup conveyor 8 in synchronization with the pickup conveyor 8.

  FIG. 2 shows the discharge guide device 10 of FIG. 1 as a plan view. The roller 13 and the like that support the belt 12 are hidden by the belt 12. Therefore, the belt 12 should be indicated by a solid line, and most of the rollers 13 and the like should be indicated by hidden lines. However, for convenience of explanation, the belt 12 is indicated by a virtual line and the parts hidden by the belt 12 by the rollers 13 and the like are indicated by solid lines.

  As the sheet material 4 to be cut on the cutting table 2, for example, a prepreg in which a carbon fiber is impregnated with a thermosetting resin such as epoxy is used. The discharge guide device 10 is disposed above the path for carrying the cut material 4a to the pickup conveyor 8. In addition, as a remaining material at the time of cutting the to-be-cut material 4a from the sheet | seat material 4, the ear | edge end 4b may remain at the side end of the width direction. The ear end 4 b may be guided outward in the width direction of the cutting table 2 without being guided to the comb 7.

  The rollers 13a and 13b on the comb 7 side and the roller 13e on the pickup conveyor 8 side are divided in the middle in the width direction. Intermediate shafts of the rollers 13a and 13b and the roller 13e are supported by the inner frame member 16 via intermediate support members 18 and 19, respectively.

  Note that the width of the belt 12 of the conveyor 11 is matched to the width of the conveyor 8 a of the pickup conveyor 8. The material to be cut 4a cut from the sheet material 4 can be discharged and guided as long as it is within the width of the belt 12. In addition, when the part of the ear end 4b is removed from the sheet material 4 and the material to be cut 4a is cut, the width of the material to be cut 4a is smaller than the width of the sheet material 4. As will be described later, a guide 12v is provided on the belt 12, and a groove 13v is provided on the roller 13 to prevent positional deviation in the width direction.

  3 shows a state in which the conveyor 11 of the discharge guide device 10 of FIG. 1 is opened in (a), and the configuration of the conveyor 11 is shown in cross section for the belt 12 in (b). As shown in FIG. 3A, the conveyor 11 can perform a swinging displacement 11a with the shaft 14b of the roller 13e on the pickup conveyor 8 side supported by the support member 17 as a base end, and becomes a free end. The comb 7 side can be opened and closed. The distance between the lower surface of the belt 12 and the upper surfaces of the comb 7 and the carry-out table 6 is sufficiently larger than the thickness of the material to be cut 4a in the open state, so that maintenance work and preparatory work such as dust removal are easily performed. be able to. The conveyor 11 is driven via a gear 14c attached to the shaft 14b of the roller 13e, and the shaft 14b that is driven from the pickup conveyor 8 side serves as the base end of the swing. Even during movement, if the path for driving the shaft 14b from the pickup conveyor 8 side is maintained and the comb 7 side is closed, the driving of the conveyor 11 can be resumed.

  Note that the transmission of the driving force may be different from the configuration in which the shaft 14b of the gear 14c involved in the transmission is used as a swing axis. For example, the driving force may be transmitted via a timing belt. Further, a dedicated drive source may be provided on the conveyor 11.

  As shown in FIG. 3B, the conveyor 11 is provided with a guide 12 v on a belt 12 that is stretched around a roller 13, and is fitted in a groove 13 v provided on the roller 13, thereby preventing positional deviation in the width direction. Since the roller 13 is not divided in the middle in the axial direction, it corresponds to the rollers 13c and 13d. However, as shown in FIG. 2, the divided rollers 13a, 13b, and 13e also have a groove 13v. .

  4 and 5 show a schematic configuration of the discharge guide device 20 of the cutting machine 1 as a second embodiment of the present invention, as a front view and a plan view, respectively. The discharge guide device 20 includes a guide plate 21 as passage guide means. The guide plate 21 is formed of an elastic metal plate or the like. The guide plate 21 has a slope of the comb 7 and a range including at least a portion of the carry-out table 6 that moves from the slope of the comb 7 from above 2 of the material to be cut 4c. Cover with an interval smaller than the thickness of the layer. Since the distance is smaller than the thickness of two layers, the material to be cut 4c passing along the lower surface of the guide plate 21 rises and overlaps even at the step portion between the surface of the cutting table 2 and the upper surface of the carry-out table 6. Passes in the unloading direction without any stagnation and is discharged stably. The material to be cut 4 c is, for example, a parallelogram, and is sequentially carried out, pushed out by the subsequent material to be cut 4 c carried out from the cutting table 2, and can pass through the carry-out table 6 from the comb 7. Note that the discharge guide device 20 can also guide a rectangular cut material 4a as shown in FIG. 2 so as to pass while preventing rising. Further, also in the discharge guide device 10 of the first embodiment, the material to be cut 4c can be guided in the same manner as the material to be cut 4a.

  The guide plate 21 is supported by being attached to both sides of the carry-out table 6 with bolts 22 at both ends in the width direction. The portion of the guide plate 21 that covers the top of the comb 7 is bent in accordance with the inclination of the upper edge of the comb 7 to form an inclined portion 21a. Further, a guide portion 21b is provided at the tip of the inclined portion 21a. The guide portion 21b is bent upward and guides the material 4c to be cut by widening the gap between the inclined portion 21a and the comb 7. A reinforcing portion 21c that is bent upward and prevents bending in the width direction is provided at the tip of the portion of the guide plate 21 that covers the top of the carry-out table 6. In the inclined portion 21a, the distance from the upper edge of the comb 7 can be made smaller than the thickness of one layer of the material to be cut 4c. Since the space | interval in the guide part 21b becomes large enough, the to-be-cut material 4c can approach from the guide part 21b, and can pass it, pushing up the inclination part 21a. The inclined portion 21a pushed up when the material to be cut 4c passes prevents the material to be cut 4c passing through the guide plate 21 as the guide means from being raised.

  6 and 7 show a schematic configuration of the discharge guide device 30 of the cutting machine 1 as a third embodiment of the present invention, as a front view and a plan view, respectively. The discharge guide device 30 includes a guide plate 31 as passage guide means. The guide plate 31 is formed of an elastic metal plate or the like, and has the inclined portion 31a and the guide portion 31b in the same manner as the inclined portion 21a and the guide portion 21b of the guide plate 21, and is the same as the guide plate 21 in the second embodiment. To work. However, the width direction is divided into a plurality, for example, two, and a gap is provided between the guide plates 31. Each guide plate 31 is supported by a support plate 32. Similarly to the guide plate 21 of the second embodiment, the support plate 32 is supported by being attached to both sides of the carry-out table 6 with bolts 33 at both ends in the width direction. The guide plate 31 is attached to the support plate 32 with bolts 34, and the upper portion of the cutting material 4a is located above the range including the slope of the comb 7 and at least the portion of the carry-out table 6 that moves from the slope of the comb 7. Covering at intervals smaller than the thickness of two layers, it operates in the same manner as the guide plate 21. In this embodiment, the material to be cut 4c shown in FIG. 5 can be guided in the same manner as the material to be cut 4a.

  According to the present embodiment, the guide plate 31 serving as the passage guide means for guiding the material to be cut 4a and 4c passing therethrough is divided into a plurality of width directions of the cutting table 2, so that the width direction of the materials to be cut 4a and 4c is divided. The guidance state can be adjusted according to the shape of the. Since the guide plates 31 divided into a plurality are spaced from each other, it is easy to confirm the passage of the cut materials 4a and 4c.

  In addition, even the conveyor 11 like Example 1 can be divided into a plurality with respect to the width direction. For example, the belt 12 shown in FIG. 3B can be divided into a plurality of parts in the width direction, and the belt 12 can be divided and passed over the same roller 13. Even if the belts 12 are separated, a plurality of belts can be used if the guides 12v are provided and the rollers 13 are provided with the grooves 13v at corresponding positions.
