Description

[Technical Field] The present invention relates to a cleaning device for a cutting machine which is capable of sucking and cleaning a chip generated when a cutting blade cuts a cloth such as a cloth. [Prior Art] In the past, a cutting machine was used at the time of cutting a sheet such as a cloth. The cutting machine can be roughly classified into an automatic type that cuts according to the cutting data, and a manual H that is directly operated by the operator, and also has a piece of cut material such as a sheet cut, and a plurality of layers. The cutter is in the state. As a cutting machine that automatically cuts the cut material one by one, a round knife is used as the cutting knife (for example, refer to Patent Document 1).

The manual cutter is a straight knife that moves back and forth along the laminating direction in the state of laminating a plurality of sheets and the like, and simultaneously cuts a plurality of sheets. On the cutting cloth fabric day, dust such as chips for cutting fabrics will be produced. In the manual cutting machine, 'because the fabric-pressing foot presses the surface of the fabric, the cutting edge is also cut by the cutter. The fabric presser foot and the elastic tube are connected to the suction pipe and connected to the (4) machine, and the technique of sucking the chips from the suction port of the suction pipe is raised (for example, 'refer to Patent Document 2). In the cutting machine, a vacuum suction type cutting machine that sucks up the cloth to make it in contact with the round knife is also proposed (see Patent Document 3). The cutting disclosed in Patent Document 3 is To prevent the fabric from dragging, the mesh separating ring is connected between the fabric and the air nozzle...the cloth is in contact with the fabric at the same speed as the cutting speed to avoid dragging the fabric and cutting the fabric for the purpose of not contacting the fabric. The cloth 6 1330676 is used to suck the air, but it can still attract the chips at the same time. _In the automatic cutting machine, the cutting table side is cut to form an endless shape f, and the rotating brush W is removed and removed. The structure of the cuttings has also been proposed (for example, reference . Document 4) Patent Document 1 Patent Document 2, Patent Document 3 Patent Document 4 reads present Patent No. 3 164 496 JP said present Laid-Open 9 the 1st 67762 JP said present Laid-Open 2001-- No. No. 3262 Publication WO 03 / 095,733

SUMMARY OF THE INVENTION In the case where a cutting material such as a cloth is cut by a cutting machine, fine chips, feathers or powdery chips are generated depending on the cloth. In particular, when the cut material is cut using a circular blade, and the surface of the cut material is not covered with the non-air permeable film, the chips adhere to the surface of the cut cloth and the surface of the sheet. The chip 'will adhere directly to the surface of the cut material from the cutting portion, or fly with the rotation of the round knife, and then fall and attach. Depending on the use of the cut, the attachment of the chips may cause problems. For example, in the case of clothing, etc., when Ιφ is cut into a cloth having a pattern having a large difference in brightness, saturation, or hue such as a black portion and a white portion, if the white portion of the chip adheres to the black portion--, or the black portion, If the chips are attached to the white part, the stain will be very conspicuous. In the use of industrial materials, if the chips adhere to the surface, they become dust and there is a risk of contamination. When the chips attached to the dicing surface are removed after cutting, the procedure is troublesome. SUMMARY OF THE INVENTION An object of the present invention is to provide a cleaning device for a cutting machine which can be prevented from adhering to a material to be cut during cutting by a simple configuration. 7 1330676 The present invention relates to a cleaning device for a cutting machine, which is provided with a cutting head of a cutting machine, which comprises: a cutting knife for cutting a cut material supported on a surface of the cutting table; and a cutting knife support Mechanism; an angular displacement mechanism that causes the support mechanism to angularly shift to change the cutting direction; and a proximity to the mechanism to displace the support mechanism in a manner to approach or away from the cutting table; while sucking the bow and sweeping along with the cutting The chipper generated is characterized in that: the movable mechanism is disposed at the end of the cutting table side of the supporting mechanism, and the branch

The holding mechanism generates a movement together with the angular displacement mechanism and the proximity away mechanism, and has an inner circumference surrounding the cutting blade and an outer peripheral surface centered at least partially on the angular displacement central axis of the angular displacement mechanism. The inner peripheral surface and the outer peripheral surface are respectively provided with an opening portion 'the inner peripheral surface opening portion communicates with the outer peripheral surface opening portion; and the 丨 mechanism' is disposed outside the movable mechanism, and has an inner side and a sixth active portion The opening of the outer peripheral surface of the mechanism communicates with the opening, and the mouth is sucked. The invention is characterized in that, when the movable mechanism is moved by the angular displacement mechanism, or is close to the near and far power consumption mechanism, the setting mechanism, the separation mechanism and the angular displacement mechanism, the attraction mechanism is in the period. ^ „ The open σ portion of the inner peripheral surface is at least temporarily connected to the opening provided on the outer peripheral surface of the core g structure. Further, the present invention is characterized in that, in the outer peripheral surface of the movable mechanism, each of the phases iw is provided with a plurality of the openings at an angle; and when the opening of the inner peripheral surface of the suction mechanism is at a predetermined angle In the opening aspect of the mechanism of the present invention, the present invention is characterized in that, in the inner peripheral side of the suction mechanism, the first eight opening portions are formed to extend along the round steam to the Μ of the present invention. shape. ^ ^ ... The scoop is characterized by the cover body on the cutting side of the movable mechanism; He Shengbei covers the aforementioned cutting body, and is at the exit of I. Further, the present invention is characterized in that the cutting blade protrudes toward the cutting table side, and the present invention is characterized in that the opposing back surface of the cover surface refers to the space of the table on the cutting table side. There are clusters around the protruding mouth

Cutting △ The feature of the present invention is that the aforementioned cutting blade is a circular knife that rotates about the axis of the parallel "it cutting table surface. #千仃于述 According to the present invention, since the cutting machine cleanly cuts the generated M and cleans the structure, the opening portion communicates with the opening portion:::: machine = squatting It attracts the chips generated by the cutting and prevents it from being cut. When the movable mechanism is moved together with the cutting blade: the opening of the outer peripheral surface of the movable mechanism is located at the position of the opening k of the suction mechanism, the attraction force can also be around the periphery of the cutting blade, so that it can be constructed by the simple 1 The chips in the cutting are attracted and removed to avoid adhesion to the cut lining. According to the present invention, the movable mechanism at least temporarily communicates with the attraction mechanism during the period of being displaced by either the proximity mechanism or the mechanism of the angular displacement mechanism or both. Moreover, according to the present invention, since the plurality of openings are provided at a predetermined angle on the outer peripheral surface of the movable mechanism, the movable mechanism can be connected to the opening of the movable mechanism when the movable mechanism is at a predetermined position of 9 1330676. During the displacement of the cutter, the attraction from the attraction mechanism is accessible to the circumference of the cutter. Further, according to the present invention, the time during which the opening of the suction mechanism communicates with the opening of the movable mechanism can be lengthened, and if the shape of the opening is adjusted, for example, any one of the plurality of openings can be connected, the attraction of the suction mechanism can be made. It often acts on the periphery of the cutting knife. Further, according to the present invention, since the cover body covering the cutting table side of the movable mechanism has a protruding opening for projecting the cutting blade toward the cutting table side, it can be produced when the cut material is cut. The chips are attracted from the protruding opening and removed by the cut portion. Further, the cut material to be cut may be curled or floated due to a decrease in suction force on the side of the cutting table. However, since the surface of the cover is closely attached to the cut material, the degree of curling or floating can be suppressed from becoming large. Further, according to the present invention, since the cover body has a space for collecting the chips around the protruding opening on the inner surface side 'opposite to the side surface of the cutting table, the chips which are flying with the cutting blade can be collected, and the prevention is prevented. Attached. Further, according to the present invention, even if the cut material is cut one by one by the round knife without covering the cut/cut material with the non-air permeable film, the swarf can be attracted to prevent it from adhering to the cut material. [Embodiment] Fig. 1 is a schematic view showing a configuration of a cutting head 3 of a cutting machine 2 equipped with a cleaning device 1 according to an embodiment of the present invention. The cutting head 3 is provided with a circular knife that rotates and cuts the sheet material 5 from the periphery as the cutting blade 4. The sheet 5 to be cut is placed on the cutting table 6. The cutting table 6 is held by vacuum suction to prevent the cut sheet 5 from deviating from below. The sheet 5 has a large air permeability, and 1330676 only uses a sheet? 5 When the holding force is insufficient, the surface of the sheet 5 is covered with a non-air permeable synthetic resin film. This non-air permeable film' is cut and cut together with the sheet 5: 4 cut. In order to cut the sheet material 5 by the cutting blade 4, the cutting blade 4 is required to pass through the sheet 5 so that the blade edge is exposed to the cutting table 6 side. Therefore, the back sheet 7 must be sandwiched between the sheet #5 and the cutting table 6 to prevent the tip from reaching the surface of the cutting table 6.

In order to remove the chips generated at the time of cutting from the periphery of the cutting blade 4, the cleaning device 1 includes the movable mechanism 8 and the suction mechanism 9. The suction pipe 1〇 is connected to the suction machine 9 to make it attractive. The movable mechanism 8 can be displaced with the cutting blade 4 for the cutting head 3. The two 6 have a substantially rectangular planar shape. The cutting head 3 is movable in the direction of the yaw axis of the cutting direction, and can move in the direction of the short side, that is, the beam extending toward the γ axis perpendicular to the y-axis direction, and moving in the direction of: The combination moves toward the X-axis direction of the beam u and moves toward the horizontal direction, and the vehicle moves from the direction.

The holder is broken. The adjusting spring 23 between the base 13 and the base 13 is slid in the conventional manner. At the lower end of the holder 18, the shaft supports an angular displacement material 24 which is displaceable about an R-axis angle parallel to the Z-axis. The position member 24 is driven by the rotation from the R-axis motor 15 on the outer peripheral side, and is angularly displaced about the R-axis. Even if the angular displacement member 24 is oriented in the z-axis direction as the holder 18 is displaced in the Z-axis direction Displacement, the R-axis motor 15 rotationally drives the rotational displacement member 24 to transmit through the gear having a thickness to maintain the driving force. The angular displacement member 24 is provided with a suction 25 whose shaft support is parallel to The rotation axis % extending in the surface direction of the cutting table 6. The rotation pumping % is arranged in the radial direction from the center of the r-axis, and the cutting blade 4 is attached to the center side. The driven (four) 22 is attached to the outside of the radial direction of the rotating shaft 26. Due to the driven pulley Μ, it is transmitted through the toothed belt 20 from the round knife The rotational driving force of the motor 17 also rotationally drives the cutting blade 4. The displacement in the Z-axis direction is performed by shifting the holder 18 by the cam mechanism 27 driven by the cam motor 16. > In the case of the suction pipe 10, a suction hose (not shown) is connected to the suction pipe 10, and is generated by a suction blower including a filter (not shown). The filter or the suction blower is used. It can be arranged in parallel with the suction blower of the suction sheet 5 on the cutting table 6, and is disposed below the cutting table 6. The movable mechanism 8 has a base body 3, which is attached to the lower end of the angular displacement member 24, and a cover body. 3, which covers the side of the cutting table 6 of the base 3〇. The cover 31 is provided at a position 7 covering the intermediate portion of the cutting blade 4, and a suction opening 32 is formed to cut the cutting blade 4 The side of the table 6 protrudes from 12 1330676 5 'causes due to the movement of the cutting table 6 due to the suction around the cutting blade 4 which suppresses curling or floating. The surface of the cut sheet is reduced in attraction or the like, and the surface of the floating body 31 is close to the sheet 5, so that the degree is increased. In the figure 2, the state of the first circle is shown to the top of the cam. When the holder 18 is raised, the holding mechanism (4) is also raised, and the cutting blade 4 is kept away from the cutting angle f?

Do not set the opening, ... as shown in the figure: = The opening portion is connected to each other in the direction of the inner circumference side, and the opening portion is raised toward the specific = structure 8, and the opening portion is not connected at any angle. The L is measured, that is, used to approach or move away from the cutting wheel 6 outer wheel mechanism 27, and may also utilize a steam red mechanism or a ball screw mechanism. The figure 3 shows the cross-sectional structure of the cross-sectional line ιπ - 3, 冓8 and the attraction mechanism 9 from the i-th image. In the movable mechanism 8, the inner circumferential side opening portion 33 and the outer circumferential side opening portion are formed at the angle of the mother compartment 90. The core material 3 is formed by the communication passage 35, and for example, a resin material can be synthesized. In the center of the base 30, a cover body is disposed around the cutting blade 4 to cover the surface side of the cutting table 6. On the inner surface of the surface side of the lid body 3, a space is provided around the suction side; = The swarf temporarily accumulates in this space 36. When the direction of the cutting blade 4 coincides with the X-axis direction or the Y-axis direction, the outer peripheral side opening portion 34 of the body 30 is in communication with the opening portion 37 provided on the inner peripheral side of the suction mechanism 9, respectively. When the direction of the cutting blade 4 is at another angle, the opening 37 of the suction mechanism 9 does not coincide with the outer peripheral opening portion 34 of the base 3G. Further, as shown in Fig. 2, when the holder 18 is raised by the cam mechanism 27, even if the cutting blade 4 coincides with the X-axis direction or the γ-axis direction, the opening portion 37 and the outer-closing opening portion 34 are not cut (4). When the cutting is performed in the X-axis direction or the y-axis direction, the opening portion 37 and the outer peripheral side opening portion 34 are aligned, and the suction force is applied to the periphery of the _ knife 4 to remove the swarf. Wait. When cutting at the curved portion, etc., even if the opening

The portion 37 does not coincide with the outer peripheral side opening portion 34, and the state in which the attraction force does not act is temporarily accumulated in the space % with the rotation of the cutting blade 4, and in the cutting, the cutting blade 4 is wound around the Han axis. When the angular displacement is in the X-axis direction or the ¥-plane direction, the opening 37 can communicate with the outer peripheral side opening portion 34 to remove the chips. Further, although the suction mechanism 9 of the present embodiment is fixed to the cutting head, the suction mechanism 9 can be moved up and down like the movable mechanism 8, or the shape of the opening portion 37 or the outer peripheral side opening portion 34 can be used. The opening 37 and the outer peripheral side opening portion 34 are connected for a longer period of time or frequently. That is, the cleaning device of the cutting machine 2! , which is attached to the cutting machine 2, the spoon is used to attract and clean the cutting mechanism 8 and the guiding mechanism 9' which are produced by the cutting. The cutting machine 2 is provided with: a cutting knife 4, which is supported by cutting a sheet 5 of a material to be cut on the surface of the cutting table 6; a support mechanism for the bearing 25 and the rotating shaft μ to find the cutting blade 4; an angular displacement member 24 and a motor 15 for the R-axis, etc. The angular displacement mechanism that the angular displacement of the support mechanism changes the cutting direction; and the convex field a, each, the γ ^ wheel motor 16 and the cam mechanism 27, etc., the basin system causes the displacement support mechanism to approach or move away from the cutting table 6 is close to the mechanism: live 14 = 8' is attached to the end of the cutting table 6 side of the support mechanism, with support 8, and the female bracelet is shifted. Among the movable mechanism positions, there are an inner circumference of the inner peripheral surface (1) of the inner peripheral surface and the R-axis of the angular shifting surface mandrel of the angular displacement mechanism, at least partially cylindrical. The cylindrical portion of the surface and the outer peripheral surface is provided with a portion inner peripheral side opening portion 33 and an outer peripheral side opening portion 34, respectively, and an inner peripheral side opening is provided.

The outer peripheral side opening portion 34 of the suction machine 1 is connected by the internal communication passage 35. The opening ^9' is disposed around the movable mechanism 8, and has a shifting period on the inner peripheral side. When the movable mechanism 8 is moved by the angle shifting mechanism and the approaching and moving mechanism, the opening 37 is at least temporarily placed in the activity. The outer peripheral side opening portion 34 of the mechanism & mouth is connected. The suction mechanism 9 is opened and passed through the outer peripheral side of the outer peripheral surface of the movable mechanism 8 that communicates with the opening portion 37. The opening portion 34 is inserted and guided, so that the movable mechanism 8 can be used. : - The inner peripheral side opening portion 33 that communicates with the mouth portion 34 is capable of attracting the chips generated by the cutting by the cutting blade =: 丨 ', and prevents it from adhering to the quilt. Since the movable mechanism 8 and the cutting blade 4 are When the outer peripheral side opening portion 34 of the movable click mechanism 8 reaches the position that communicates with the opening portion 37 of the suction mechanism 9, the attraction force of the suction mechanism 9 is also applied to the cutting blade 4. Therefore, it is possible to avoid the adhesion of the chips in the cutting to the cut material by a simple construction. On the outer peripheral surface of the base 3' of the movable mechanism 8, a plurality of outer peripheral sides are provided at predetermined angles (for example, at intervals of 9 G. Four or the like are provided). Department W. Since the opening portion 37 on the inner peripheral side of the guide mechanism 9 is connected to the outer peripheral side opening portion 34 15 1330676 of the movable mechanism 8 only when the movable mechanism 8 is at the same angle position, it can be cut. During the displacement of 4, the passage from the openings is such that the suction force from the suction mechanism 9 is around the cutting blade 4.

The movable mechanism 8 is provided with a lid body 31 covering the side of the cutting table 6. On the lid body 31, the cutting blade 4 protrudes from the side of the cutting table 6. Since the suction port 32 of the bow I is carried out from the periphery of the self-cutting cutter 4, the cutting shoulder generated when the cut material is cut can be sucked from the suction port 32 and removed from the cut portion. 31. On the inner surface side facing the side surface of the cutting table 6, since the space around the suction port 32 has the space 36 for collecting the chips, the chips flying by the cutting blade 4 can be gathered to prevent reattachment. The outer peripheral side opening portion 34 communicates with the suction mechanism 9 from the opening portion 37 to perform suction and entanglement, and accumulates in the space 36. The shavings and the like can be removed and removed by the suction airflow. Fig. 5 is a view showing the structure of the movable mechanism 48 and the suction mechanism 49 of the cleaning device according to another embodiment of the present invention. Except for the movable mechanism 48 and the suction mechanism 49, other parts are Since the cleaning device 1 of the embodiment of the drawings is the same, the illustration is omitted. The same reference numerals are used to designate the corresponding portions in the figured blade, and the repeated description is omitted. The tongue movement mechanism 48' is basically the same as the third figure. In the same manner as the movable mechanism 8, four inner circumferential side opening portions 43, outer circumferential side opening portions 44, and communication passages 45 are formed in the base 40. The same applies to the lid body 31. The suction mechanism 49 is formed with a & circumferential direction. The extended opening portion 50 can communicate with the periphery of the cutting blade 4 by the suction machine set 49 regardless of the direction in which the cutting blade 4 is in contact with the opening portion 50 and the outer peripheral side opening portion 44. Further, the movable machine can be moved. 16 1330676 The opening portion 44 on the side of the structure 48 is formed in a shape extending in the circumferential direction. The opening portion 5A on the inner peripheral side of the suction mechanism 49 or the outer peripheral side of the movable mechanism 48 is opened. p 44 is formed in a shape extending in the circumferential direction. , It is possible to extend the interval between the opening 50 of the suction mechanism 49 and the opening of the outer peripheral side of the movable mechanism 48. The shape of the right adjustment opening 44, 5, for example, allows any of the plurality of openings 44, 50 to communicate. Then, the attraction force of the attraction mechanism 49 can be often applied to the periphery of the cutting blade 4.

In the embodiment described above, since the cutting blade 4 is wound around a circular knife parallel to the axis of the surface of the cutting table 6, there is also a state in which the cut material is not covered by the non-air permeable film. The case of cutting. Even in this case, the cutting portion which is attracted to the cutting force 4 can be generated or the chips which are flying with the cutting blade 4 can be prevented from adhering to the cut material. Further, in the case where the cutting blade 4 is not a circular knife, the present invention can be applied similarly to the cleaning around the cutting blade. Further, the suction blowers that attract the suction mechanisms 9 and 49 are controlled such that the openings 3 7 and 5 〇 of the suction mechanisms 9 and 49 communicate with the outer peripheral side openings 34 and 44 of the movable mechanism 8 ′48. 0Ν (ON), or can be controlled to be 〇n (ON) not only when connected but also when it is necessary to attract.
