The present application is a U.S. National Phase of PCT/JP2016/054252 filed on Feb. 15, 2016. The disclosure of the PCT Application is hereby incorporated by reference into the present Application.
The present invention relates to a cutting apparatus and a cutting blade used in the cutting apparatus.
In various industrial fields, an extruder extruding a highly-viscous substance (clay-like substance) is used. Generally, as described in Patent Document 1, the extruder is loaded with a highly-viscous substance in an extruder main body and extrudes the highly-viscous substance in the extruder main body with a pressing tool from a nozzle of the extruder main body into a rod shape and the extruded elongated-shaped highly-viscous substance is cut by a cutting blade at a predetermined length from a leading end. In this case, if the elongated-shaped highly-viscous substance is sheared by one cutting blade, the elongated-shaped highly-viscous substance may bend in the shearing direction at the time of shearing and may no longer be accommodated in an incorporating object, and it is therefore proposed to eject liquid nitrogen toward the extruded elongated-shaped highly-viscous substance before cutting by the one cutting blade to cool and harden the rod-like highly-viscous material so that the cooled and hardened elongated-shaped high substance is cut by using the one cutting blade (see Patent Document 1).
However, if the elongated-shaped highly-viscous substance is cooled and hardened by using liquid nitrogen as described above, a complicated ejecting mechanism is required for ejecting liquid nitrogen, and moreover, a running cost based on the use of liquid nitrogen must be taken into consideration.
Therefore, the present inventor has developed a cutting apparatus having a pair of cutting blades that are respectively provided to be capable of approaching/separating movement on both sides relative to the elongated-shaped highly-viscous substance being extrude and that are arranged with blade edge parts thereof facing each other while having the thickness directions of the paired cutting blades oriented in the elongation direction of the highly-viscous substance. This enables the pair of cutting blades to cut the elongated-shaped highly-viscous substance from both left and right sides through the approaching movement toward each other, and the elongated-shaped highly-viscous substance can be restrained from bending to one side at the time of cutting. As a result, neither a liquid nitrogen ejector structure nor liquid nitrogen used therewith is required for restraining the elongated-shaped highly-viscous substance from bending to one side, so that the configuration can be simplified.
Patent Document 1: Japanese Laid-Open Patent Publication No. 4-232318
However, if an elongated-shaped highly-viscous substance is cut by a pair of cutting blades as described above, blade edge parts of the pair of cutting blades come into contact with each other and, therefore, a damage may occur in the blade edge parts, which are the weakest parts of the cutting blades.
The present invention was conceived in view of such a circumstance and it is therefore a first object of the present invention to provide a cutting apparatus not only capable of restraining a highly-viscous substance from bending by using a simple configuration at the time of cutting of the elongated-shaped highly-viscous substance but also capable of preventing a damage of a blade edge part as much as possible.
A second object is to provide a cutting blade used in the cutting apparatus.
To achieve the first object, the present invention has configurations of (1) to (10).
(1) In a cutting apparatus having a pair of cutting blades provided to be capable of approaching/separating movement, the cutting blades being arranged with blade edge parts thereof facing each other while having thickness directions thereof oriented in the same direction,
the cutting blades each have a thickness gradually increased from a blade edge leading end toward a blade root part,
the cutting blades each have the blade edge part offset from the blade edge part of the counterpart cutting blade in the thickness direction of the cutting blades within a range facing a thickness-direction surface of the counterpart cutting blade, and
the cutting blades each have the thickness-direction surface made of a material having a hardness lower than that of the blade edge part of the counterpart cutting blade at least in a region faced by the blade edge part of the counterpart cutting blade.
According to this configuration the elongated-shaped highly-viscous substance can be cut from both left and right sides relative to the substance through the approaching movement of the pair of cutting blades, so that the highly-viscous substance can be restrained from bending at the time of cutting even without providing a liquid nitrogen ejecting mechanism etc.
On the other hand, the cutting blades each having a thickness gradually increased from a blade edge leading end toward a blade root part are used as a pair of cutting blades; the cutting blades each have the blade edge part offset from the blade edge part of the counterpart cutting blade in the thickness direction of the cutting blades within a range facing a thickness-direction surface of the counterpart cutting blade; the cutting blades each have the thickness-direction surface made of a material having a hardness lower than that of the blade edge part of the counterpart cutting blade at least in a region faced by the blade edge part of the counterpart cutting blade; therefore, a direct contact between the blade edge parts can be avoided at the time of cutting of the highly-viscous substance and, accordingly, even if the blade edge part comes into contact with the thickness-direction surface of the counterpart cutting blade, the weakest part, i.e., the blade edge part, of the cutting blade can be prevented from being damaged based on the fact that at least a region faced by the blade edge part of the counterpart cutting blade is made of a material having a hardness lower than that of the blade edge part of the counterpart cutting blade.
Therefore, the highly-viscous substance can be restrained from bending by using a simple configuration at the time of cutting of the elongated-shaped highly-viscous substance and, additionally, a damage of the blade edge parts can be prevented as much as possible.
(2) Under the configuration of (1),
the blade edge parts of the cutting blades are made of a metal.
According to this configuration, since the blade edge parts of the cutting blades are made of a metal, the highly-viscous substance can precisely be cut, and in this case, even if the blade edge part made of a metal comes into contact with the thickness-direction surface of the counterpart cutting blade, the blade edge part can be prevented from being damaged based on the fact that at least a contact region thereof is made of a material having a hardness lower than that of the metal. Therefore, the same effects as (1) described above can specifically be acquired.
(3) Under the configuration of (2),
the cutting blades each have the thickness-direction surface formed of a resin surface at least in a region faced by the blade edge part of the counterpart cutting blade.
According to this configuration, even if the blade edge part of the counterpart cutting blade made of a metal comes into contact with the thickness-direction surface of the cutting blade, the blade edge part of the counterpart cutting blade can be prevented from being damaged based on the resin surface in a contact region thereof.
(4) Under the configuration of (3),
the cutting blades each have a surface formed of a resin surface except a blade edge surface.
According to this configuration, the highly-viscous substance can be prevented from adhering to the cutting blade in association with the cutting of the highly-viscous substance and, even if the cutting blade is continuously used, the highly-viscous substance can be restrained from being bent by the highly-viscous substance adhering to the cutting blade at the time of cutting of the highly-viscous substance.
(5) Under the configuration of (1),
the cutting blades each have the thickness-direction surface with a shape extending from the blade edge leading end to the blade root part while maintaining a constant width, and
the blade edge leading ends of the cutting blades are each inclined as one end of the thickness-direction surface with respect to the width direction of the cutting blades and are arranged in parallel with each other.
According to this configuration, at the time of cutting of the highly-viscous substance, a use position of the blade edge leading end of each of the cutting blades (a position of contact with the highly-viscous substance) is continuously changed in accordance with the approaching movement of the two cutting blades, so that the blade edge leading ends of the cutting blades can effectively be utilized in the range in the width direction. Therefore, as compared to those without the change in the use position of the blade edge leading ends of the cutting blades, a cutting load can be reduced so as to extend the usable period (period before replacement) of the cutting blades.
(6) In a cutting apparatus having a pair of cutting blades provided to be capable of approaching/separating movement, the cutting blades being arranged with blade edge parts thereof facing each other while having thickness directions thereof oriented in the same direction,
the cutting blades each have a thickness gradually increased from a blade edge leading end toward a blade root part,
the cutting blades each have the blade edge part offset from the blade edge part of the counterpart cutting blade in the thickness direction of the cutting blades within a range facing a thickness-direction surface of the counterpart cutting blade, and the cutting blades are each formed of a resin surface at least on a blade edge surface thereof and a region faced by the blade edge part of the counterpart cutting blade on the thickness-direction surface thereof.
According to this configuration, even though the blade edge surfaces of a pair of the cutting blade are resin surfaces, the highly-viscous substance can precisely be cut without bending and, since the thickness-direction surface of each of the cutting blades is formed of a resin surface in the region faced by the blade edge part of the counterpart cutting blade, the blade edge parts of the cutting blades can be prevented from being damaged.
Therefore, the cutting apparatus also can not only cut the highly-viscous substance while restraining the highly-viscous substance from bending by using a simple configuration, but also prevent a damage of the blade edge parts as much as possible at the time of cutting.
(7) Under the configuration of (6),
the cutting blades each have the entire surface formed of a resin surface.
According to this configuration, the highly-viscous substance can be prevented from adhering to the cutting blade in association with the cutting of the highly-viscous substance by using the resin surface and, even if the cutting blade is continuously used, the highly-viscous substance can be restrained from being bent by the highly-viscous substance adhering to the cutting blade at the time of cutting of the highly-viscous substance.
(8) Under the configuration of (7),
the cutting blades each include a core material having a rigidity higher than that of a resin constituting the resin surface, and
the entire surface of the core material is coated with the resin.
According to this configuration, the highly-viscous substance can be prevented from adhering to the cutting blade at the time of cutting (the use of the cutting blade with the highly-viscous substance adhering thereto can be avoided) by using a coating resin, and the rigidity of the cutting blades can be ensured by the core material coated with the coating resin.
(9) Under the configuration of (6),
the cutting blades each have a core material having the same shape as the cutting blades and a rigidity higher than that of a resin constituting the resin surface, and
a resin tape is affixed to thickness-direction surfaces on both sides of the core material from a blade edge leading end to a blade root part of the core material.
According to this configuration, by using the resin tape and the core material, the cutting apparatus substantially producing the same effects as (8) described above can easily be acquired.
(10) Under the configuration of (6),
the cutting blades each have the thickness-direction surface with a shape extending from the blade edge leading end to the blade root part while maintaining a constant width, and
the blade edge leading ends of the cutting blades are each inclined as one end of the thickness-direction surface with respect to the width direction of the cutting blades and are arranged in parallel with each other.
According to this configuration, at the time of cutting of the highly-viscous substance, a use position of the blade edge leading end of each of the cutting blades (a position of contact with the highly-viscous substance) is continuously changed in accordance with the approaching movement of the two cutting blades, so that the blade edge leading ends of the cutting blades can effectively be utilized in the range in the width direction. Therefore, as compared to those without the change in the use position of the blade edge leading ends of the cutting blades, a cutting load can be reduced so as to extend the usable period (period before replacement) of the cutting blades.
To achieve the second object, the present invention has configurations of (11) to (19).
(11) In a cutting blade used as one of a pair of cutting blades having respective thickness-direction surfaces overlapping with each other from a blade edge leading end toward a blade root part when the cutting blades are allowed to perform an approaching movement toward each other with thickness directions thereof oriented to the same direction,
the cutting blade has a thickness gradually increased from the blade edge leading end toward the blade root part,
the cutting blade has the thickness-direction surface made of a material having a hardness lower than that of the blade edge part at least in a region to be contacted with a counterpart blade edge part.
According to this configuration, the cutting blade used in (1) described above can be provided.
(12) Under the configuration of (11),
the blade edge part is made of a metal.
According to this configuration, since the blade edge part is made of a metal, the same effects as (11) described above can specifically be acquired.
(13) Under the configuration of (12),
the thickness-direction surface is formed of a resin surface at least in a region to be contacted with the counterpart blade edge part.
According to this configuration, the cutting blade used in (3) described above can be provided.
(14) Under the configuration of (11),
the thickness-direction surface has a shape extending from the blade edge leading end to the blade root part while maintaining a constant width, and

the cutting blade has a thickness gradually increased from the blade edge leading end toward the blade root part,
at least the thickness-direction surfaces on both sides are formed of resin surfaces from the blade edge leading end toward the blade root part.
According to this configuration, the cutting blade used in (6) described above can specifically be provided.
(16) Under the configuration of (15),

As shown in
The extruder main body 5 contains the metallic sodium 2, and the extruder main body 5 includes a cylindrical storage container 7 and a nozzle 8 provided on one end side of the storage container 7 to close an opening on the one end side. The cylindrical storage container 7 is attached to an attaching frame 10 (see
The pressing tool 6 has a lower end side slidably fitted into the storage container 7 as a pressing part. An upper end portion of the pressing tool 6 is coupled to a drive mechanism not shown, and the pressing tool 6 is pushed down by driving the drive mechanism. As a result, the metallic sodium 2 in the extruder main body 5 is linearly extruded through the nozzle 8 (the squeezing hole 9) to the outside (see an imaginary line of
This extruded metallic sodium 2 is obviously adjusted by controlling the drive mechanism (the pressing tool 6). Specifically, the drive mechanism (the pressing tool 6) is stopped on condition that the length of the extruded metallic sodium 2 reaches a certain length from the leading end, and when the cutting by the cutting apparatus 4 described later is finished to achieve a state satisfying a start condition of freshly extruding the metallic sodium 2, the drive mechanism (the pressing tool 6) is driven again.
As shown in
The pair of the guide bars 13, 13 is attached to the mounting frame 10 in a vertically arranged state. As shown in
Each of the paired holders 14 includes a plate-like sliding part 18 held in a state of bridging between the paired guide bars 13, 13, and a holding part 19 provided integrally with the sliding part 18. Each of the sliding parts 18 is penetrated by the pair of the guide bars 13, 13, so that the sliding parts 18 can be guided by the pair of the guide bars 13, 13 to enable approaching/separating movement with respect to each other. The sliding parts 18 are projected forward from the pair of the guide bars 13, 13, and each of projected leading end portions of the sliding parts 18 is protruded forward from a front surface 15b of the support post part 15. The holding parts 19 are respectively provided on facing surfaces 18a of the sliding parts 18 facing each other. The holding parts 19 are each formed in a state of protruding toward the counterpart sliding part 18, and an upper surface 19a of each of the holding parts 19 is formed as a flat surface. An attachment hole 19b is opened in the upper surface 19a of the holding part 19, and a fastener 45 can be screwed into the attachment hole 19b.
Each of the paired cutting blades 20 is formed in a band plate shape. Each of the cutting blades 20 has a blade root part 21 side placed on the upper surface 19a of the holding part 19 such that the thickness direction thereof (the vertical direction of
The paired air cylinder devices 16 are respectively attached to the front surface 15b of the support post parts 15 for the purpose of driving the holders 14 and the cutting blades 20. Extendible rods 16a of the air cylinder devices 16 are coupled to the holders (projected parts) 14, and the two holders 14 perform approaching/separating movement in accordance with the extending/retracting movement of the extensible rods 16a of the air cylinder devices 16. Accordingly, the two cutting blades 20, 20 perform the approaching/separating movement, and the extruded rod-like metallic sodium 2 is cut by the two cutting blades 20, 20.
Obviously, the air cylinder devices 16 each include an electromagnetic valve mechanism (air cylinder drive adjustment mechanism) adjusting supply and discharge of compressed air from a compressed air source not shown, and the control and adjustment thereof achieve the approaching/separating movement of the pair of the cutting blades 20, 20 described above. Specifically, on condition that the metallic sodium 2 extruded from the extruder 3 reaches a certain length and the pressing tool 6 (the drive mechanism) is stopped, the pair of the cutting blades 20, 20 separated until then is allowed to perform the approaching movement by controlling the solenoid valve mechanisms, and the pair of the cutting blades 20, 20 cuts the metallic sodium 2. After this cutting, the paired cutting blades 20, 20 are immediately separated (returned to standby positions).
As shown in
The support plate 25 is provided with an introduction hole 28 faced by the squeezing hole 9 in the nozzle 8, and the introduction hole 28 penetrates between the upper and lower surfaces of the support plate 25. The guide cylinder 26 has an upper end opening facing the squeezing hole 9 in the nozzle 8 and a lower end opening facing the introduction hole 28. The positioning recess 27 is formed into a circular shape around the introduction hole 28 so that a head 30 of the poppet valve intermediate 11 serving as an incorporating object is fitted thereto, and the introduction hole 28 is opened in the positioning recess 27.
In the receiving mechanism 12, when the poppet valve intermediate 11 is filled (supplied) with the cut metallic sodium 2 described above, the head 30 of the poppet valve intermediate 11 is fitted in advance to the positioned recess 27 by utilizing a conveying apparatus 32. Obviously, as shown in
The cutting apparatus 4 used in the supplying apparatus 1 as described above and the cutting blades 20 used in the cutting apparatus 4 are devised in consideration of durability, workability, etc.
The paired cutting blades 20 used in the cutting apparatus 4 each have a surface (hereinafter referred to as a thickness-direction surface) 35a (35b) facing in the thickness direction of the cutting blade 20 (vertical direction of
As shown in
As shown in
The cutting blades 20 are each formed by using a metal material 38 and a resin material 37 in consideration of the structure of the inclined surface 36a (36b). The metal material 38 integrally forms the entire blade edge part 23 including the blade edge surface 23s, the entire blade root part 21, and a coupling plate part 39 coupling the blade edge part 23 and the blade root part 21 with the maximum thickness of the blade edge part 23 and, in this embodiment, the blade edge surface 23s is made up of a metal surface. For this metal material 38, for example, any one of stainless steel, alloy tool steel, etc. is used in consideration of being used as the blade edge part 23.
The resin material 37 is integrated with each of thickness-direction surfaces 35a, 35b of the coupling plate part 39. The resin material 37 is provided such that a thickness increases toward the blade root part 21, and this resin material 37 forms a resin surface (hereinafter denoted by reference numeral 24s of the buffer surface) as the buffer surface 24s continuous to the blade edge surface 23s. The resin material 37 is preferably, for example, a material having a hardness considerably lower than the blade edge part 23 made of a metal and exhibiting high releasability for the metallic sodium 2 and, specifically, a thermoplastic resin etc. are preferable.
In this embodiment, the angle of the blade edge part 23 of each of the cutting blades 20 (the angle formed by the thickness-direction surfaces 35a, 35b on both sides) is set to a comparatively sharp angle, for example, 10° to 30°. This is because, when the angle of the blade edge part 23 is set to a sharp angle, the metallic sodium 2 is cut well although the blade edge part 23 is more easily damaged or chipped as compared to when the angle of the blade edge part 23 is set to an obtuse angle, and the braking and the chipping of the blade edge part 23 can be suppressed by the cutting blade 20 and the cutting apparatus 4 using the cutting blade 20 as described later.
As described above, the blade edge part 23 of each of the paired cutting blades 20 of the cutting apparatus 4 is vertically offset with respect to the blade edge part 23 of the counterpart cutting blade 20 as shown in
Therefore, when the paired cutting blades 20 are allowed to perform the approaching operation in the supplying apparatus 1, as shown in
On the other hand, since the blade edge part 23 of each of the cutting blades 20 is offset with respect to the blade edge part 23 of the counterpart cutting blade 20 in the vertical direction within a range facing the resin surface 24s of the counterpart cutting blade 20, the contact between the blade edge leading ends 23a can be avoided at the time of cutting of the metallic sodium 2 and, additionally, even if the blade edge part 23 comes into contact with the thickness-direction surface 35a (35b) of the counterpart cutting blade 20 as shown in
In this embodiment, since the portion of the inclined surface 36a (36b) except the blade edge surface 23s is formed as the resin surface 24s, and a large portion involved in cutting is the resin surface 24s exhibiting the releasability for the metallic sodium 2, the metallic sodium 2 can be prevented from adhering to the cutting blade 20 in association with the cutting of the metallic sodium 2 and, even if the cutting blade 20 is continuously used, the metallic sodium 2 can be restrained from being bent by the metallic sodium 2 adhering to the cutting blade 20 at the time of cutting of the metallic sodium 2.
The second embodiment 220 shown in
As a result, at the time of cutting of the metallic sodium 2, a use position of the blade edge leading end 23a of each of the cutting blades 220 (a position of contact with the metallic sodium 2) is continuously changed in accordance with the approaching movement of the two cutting blades 220, 220 as shown in
In this embodiment, the metal material 38 forms a shape close to the cutting blade shape, and the resin material 37 is applied as a film onto the surface of the metal material 38 except the blade edge surface 23s made of the metal material 38.
As a result, the resin surface 24a of the film (the resin material 37) can prevent the damage of the blade edge part 23 on the inclined surface 36a (36b) of the cutting blade 220 and, additionally, the metallic sodium 2 can further be restrained from adhering to the whole of the cutting blades 220 in association with the cutting of the metallic sodium 2, so that the use period of the cutting blades 220 can more preferably be extended.
It is noted that the film of the resin material 37 of
In the third embodiment 320 shown in
As a result, the entire surface of the cutting blade 320 is formed of the resin surface 24s, so that the metallic sodium 2 can further be restrained from adhering to the cutting blades 320, while preventing the damage of the blade edge part 23.
In this case, although the blade edge surface 23s is also made up of the resin surface 24s, the metal material 38 serves as a core material for the resin material 37, sufficient rigidity can be ensured for the cutting blade 320. Therefore, even when the cutting blades 320 are used in the cutting apparatus 2, the metallic sodium 2 can precisely be cut.
The fourth embodiment 420 shown in
As a result, cutting blades 420 substantially the same as those of the third embodiment 320 can be acquired.
In this embodiment, the resin tape 41 is present within a certain distance from the leading end of the metal material 38 toward the blade root part 21; however, obviously, the resin tape 41 maybe affixed to the entire thickness-direction surfaces 38a, 38b on both sides of the metal material 38.
The fifth embodiment 520 shown in
Therefore, even if the blade edge leading end 23a of each of the cutting blades 520 comes into contact with the inclined surface 36 of the counterpart cutting blade 520 at the time of cutting of the metallic sodium 2, the entire surface including the inclined surface 36 is formed of the resin surface 24s (the coating surface of the resin material 37) and, therefore, the blade edge part 23 can be prevented from being damaged. Additionally, since the entire surface of each of the cutting blades 520 is formed of the resin surface 24s, the metallic sodium 2 can be restrained from adhering to the cutting blades 520 at the time of cutting of the metallic sodium 2 as is the case with the third embodiment 320, so that the use period of the cutting blades 520 can preferably be extended.
Although the embodiments have been described, the present invention include the following forms.
(1) Besides the resin material 37, a material other than the resin material 37 such as rubber is used as the material having a hardness lower than that of the blade edge part 23.
(2) In the first embodiment, coating with the resin material 37 is applied except the blade edge parts 23.
(3) The form of the blade edge parts 23 of the second embodiment is applied to forms (the third to fifth embodiments) in which the inclined surfaces 36 (36a, 36b) are entirely formed of the resin surfaces 24s.
(4) The cutting blades according to the third and fifth embodiments 320, 520 are entirely made only of the resin material 37.
