Description

  The present invention relates to a continuous wave cutting device.

  2. Description of the Related Art Conventionally, a continuous wave-like body cutting device that cuts a continuous wave-like body into individual wave-like members is known. For example, in Patent Document 1, two upper and lower cutting blades that are provided so as to be able to sandwich a continuous corrugated body from the upper and lower directions and the upper and lower cutting blades and the upper and lower cutting blades can be moved back and forth in the vertical direction. A continuous wave-shaped body cutting apparatus is described that includes two rotating cams and an outer gear that has an opening through which a lower cutting blade can project and can send the continuous wave-shaped body in the rotational direction.

JP-A-2-36091

  However, in the continuous wave cutting device described in Patent Document 1, each of the two rotating cams is driven by a different motor. For this reason, when cutting a continuous wave body at a comparatively high speed, there exists a possibility that rotation of two rotary cams may shift | deviate by rapid acceleration / deceleration. If the rotation of the two rotating cams is deviated, the upper and lower cutting blades cannot contact the continuous wave body at the same timing, and therefore the continuous wave body cannot be cut at a desired position.

  The present invention has been made in view of the above problems, and an object thereof is to provide a continuous wave-like body cutting device capable of cutting a continuous wave-like body to a desired length at high speed and with high accuracy.

  The present invention is a continuous wave-like body cutting device capable of cutting a continuous wave-like body (8), and includes a first cutting blade (20), a first cutting blade support portion (25), an outer gear (30), and an outer restraint gear. (40), a second cutting blade (45), a second cutting blade support portion (50), a rotating cam (55), and a support drive force generation portion (60).

The first cutting blade is provided so as to come into contact with the first surface (81) of the continuous wave-like body.
The first cutting blade support portion is rotatable while supporting the first cutting blade so that the first cutting blade can reciprocate in a cutting direction capable of cutting the continuous wave-like body.
The outer gear is provided to be rotatable in the radially outward direction of the first cutting blade support portion. The outer gear is formed on the outer wall surface so that the continuous wave-like body can be fed, and on the outer wall surface so that the first cutting blade can protrude when the first cutting blade comes into contact with the continuous wave-like body. Has an opening.
The outer restraining gear is rotatably provided integrally with the first cutting blade support portion, and is provided so as to be able to engage with the outer gear.
The second cutting blade is provided so as to come into contact with the second surface (82) opposite to the first surface of the continuous wave-like body. The second cutting blade can cut the continuous wave body by contacting the continuous wave body together with the first cutting blade.
The second cutting blade support portion can rotate in synchronization with the first cutting blade support portion while supporting the second cutting blade so that the second cutting blade can reciprocate in the cutting direction.
The rotating cam is provided so as to be able to come into contact with the second cutting blade, and can push the second cutting blade toward the continuous wave body along the cutting direction.
The support driving force generator is connected to the first cutting blade support and the second cutting blade support, and generates a rotational force capable of rotating the first cutting blade support and the second cutting blade support.
In the continuous wave cutting device of the present invention, the outer restraining gear engages with the outer gear when the first cutting blade projects from the opening.

  In the continuous wave-shaped cutting device of the present invention, the outer restraining gear that can be engaged with the outer gear rotates in synchronization with the rotation of the first cutting blade support portion and the second cutting blade support portion. Here, “synchronously rotate” means that they are rotating at the same angular velocity. In addition, the outer restraining gear engages with the outer gear when the first cutting blade projects from the opening of the outer gear. Thus, when the continuous wave-like body is cut by the first cutting blade and the second cutting blade, the outer restraint gear restrains the rotation of the outer gear, and the position of the first cutting blade supported by the first cutting blade support portion And the position of the opening are the same. When the first cutting blade that is in the same position as the opening protrudes from the opening, the continuous wave-like body is cut together with the second cutting blade.

  Thus, in the continuous wave-like body cutting device of the present invention, even when the rotation of the outer gear rotating separately from the rotation of the outer restraining gear is deviated, the rotation of the outer gear is restrained by the outer restraining gear when cutting the continuous wave-like body. The position of the first cutting blade and the position of the opening are made the same. Thereby, since a 1st cutting blade protrudes from an opening reliably, a continuous wave body can be cut | disconnected reliably with a 2nd cutting blade. Therefore, in the continuous wave body cutting apparatus of the present invention, even when the outer gear rotates at a relatively high speed, when the continuous wave body is cut by the first cutting blade and the second cutting blade, the position of the first cutting blade is Since the position of the opening can be made the same, the continuous wave body can be cut to a desired length at high speed and with high accuracy.

  Next, the operation of the cutting device 1 will be described. In FIG. 4, the conceptual schematic diagram of the cutting device 1 when cut | disconnecting the continuous wave body 8 is shown. 4-6, the structure which supports the 1st cutting blade 20 of the 1st cutting blade support part 25 is simplified for convenience. 5 and 6 show temporal changes on the first cutting blade 20 side in the cutting apparatus 1, and for example, FIG. 5 (a-1) and FIG. 5 (a-2) are the same. The state in time is shown, and FIGS. 5B-1 and 5B-2 show the state in time subsequent to FIGS. 5A-1 and 5A-2. 5 (c-1) and (c-2) and FIGS. 6 (a-1) and (a-2) show the states at the same time. 5 and 6, the scale of each member and the positional relationship of the rotation shaft are changed from the state shown in FIG. 4 in order to make the relationship between the members easy to understand.

  The states shown in FIGS. 5A-1 and 5A-2 are as follows. In the cutting apparatus 1, the desired cutting position of the continuous wave-like body 8 is between the first cutting blade 20 and the second cutting blade 45. Not. At this time, the outer gear 30 and the outer restricting gear 40 rotate individually without the inner teeth 32 of the outer gear 30 and the restricting outer teeth 41 of the outer restricting gear 40 engaging with each other, as shown in FIG. doing. Further, as shown in FIG. 5B-1, the outer gear 30 and the first cutting blade support portion 25 are accommodated in the outer gear 30 by the first cutting blade 20 supported by the first cutting blade support portion 25. It is rotating as it is.

  When the outer gear 30, the outer restraint gear 40, and the first cutting blade support portion 25 are rotated from the state shown in FIGS. 5 (a-1) and (a-2), as shown in FIG. 5 (b-1), The restraining outer teeth 41 of the outer restraining gear 40 and the inner teeth 32 of the outer gear 30 begin to mesh. At this time, as shown in FIG. 5 (b-2), the position of the first cutting blade 20 supported by the first cutting blade support portion 25 is a position that can project from the opening 300 of the outer gear 30. The rotation of the outer gear 30 and the rotation of the first cutting blade support portion 25 are synchronized. The rotation angle of the first cutting blade 20 in FIG. 5B-2 is defined as a synchronization start angle Ps20.

  When the outer gear 30, the outer restraint gear 40, and the first cutting blade support portion 25 are rotated from the state shown in FIGS. 5B-1 and 5B-2, as shown in FIG. The restraining outer teeth 41 of the outer restraining gear 40 and the inner teeth 32 of the outer gear 30 are completely meshed with each other. Thereby, the rotation of the outer restraint gear 40 and the rotation of the outer gear 30 are synchronized. At this time, as shown in FIG. 5 (c-2), the first cutting blade 20 supported by the first cutting blade support portion 25 protrudes from the opening 300 of the outer gear 30.

When the first cutting blade 20 projects from the opening 300 of the outer gear 30, the apex of the cam crest 571 of the rotating cam 55 is in contact with the cam follower 49 on the second cutting blade 45 side, as shown in FIG. 4. Thereby, the second cutting blade 45 protrudes from the opening 510 of the rotary drum 51.
When the first cutting blade 20 protruding from the opening 300 of the outer gear 30 and the second cutting blade 45 protruding from the opening 510 of the rotating drum 51 abut on a desired position of the continuous wave body 8, the continuous wave body 8 is The corrugated fin 5 is cut by the length of That is, when the first cutting blade 20 side is in the state shown in FIGS. 5C-1 and 5C-2, the continuous wave-like body 8 is cut.

  From the state shown in FIGS. 6A-1 and 6A-2, which is the same as FIGS. 5C-1 and 5C-2, the outer gear 30, the outer restraining gear 40, and the first cutting blade support portion 25 are provided. Is rotated, as shown in FIG. 6 (b-1), the meshing between the restraining outer teeth 41 of the outer restraining gear 40 and the inner teeth 32 of the outer gear 30 starts to be released. At this time, as shown in FIG. 6 (b-2), the first cutting blade 20 supported by the first cutting blade support portion 25 is accommodated in the outer gear 30. The rotation angle of the first cutting blade 20 in FIG. 6B-2 is defined as a synchronization end angle Pe20.

  When the outer gear 30, the outer restraining gear 40, and the first cutting blade support portion 25 are rotated from the state shown in FIGS. 6B-1 and 6B-2, as shown in FIG. The meshing between the restraining outer teeth 41 of the outer restraining gear 40 and the inner teeth 32 of the outer gear 30 is completely released. In other words, a free state is established in which the rotation of the outer restraint gear 40 and the rotation of the outer gear 30 are completely unrelated. At this time, as shown in FIG. 6 (c-2), the first cutting blade 20 supported by the first cutting blade support portion 25 is completely accommodated in the outer gear 30.

  In the cutting device 1 according to the embodiment, the outer restraint gear 40 that can be engaged with the outer gear 30 rotates in synchronization with the rotation of the first cutting blade support portion 25 and the second cutting blade support portion 50. Further, the outer restraint gear 40 engages with the outer gear 30 only when the first cutting blade 20 protrudes from the opening 300 of the outer gear 30. Thereby, when the continuous wave-like body 8 is cut by the first cutting blade 20 and the second cutting blade 45, the outer restraint gear 40 restrains the rotation of the outer gear 30 and is supported by the first cutting blade support portion 25. The position of the first cutting blade 20 and the position of the opening 300 are made the same. When the first cutting blade 20 located at the same position as the opening 300 protrudes from the opening 300, the continuous corrugated body 8 is cut together with the second cutting blade 45. Specifically, the outer restraint gear 40 rotates the outer gear 30 in an angle range in a synchronization section Sa20 between the synchronization start angle Ps20 in FIG. 5 (b-2) and the synchronization end angle Pe20 in FIG. 6 (b-2). Therefore, the first cutting blade 20 can be protruded from the opening 300.

  Thus, in the cutting device 1 according to the embodiment, even when the rotation of the outer gear 30 that rotates separately and the rotation of the outer restraint gear 40 are deviated, the outer restraint gear 40 causes the outer gear 30 to be cut when the continuous wave body 8 is cut. The rotation is constrained so that the position of the first cutting blade 20 and the position of the opening 300 are the same. Thereby, since the 1st cutting blade 20 protrudes from the opening 300 reliably, the continuous wave body 8 with the 2nd cutting blade 45 can be cut | disconnected reliably. Therefore, in the cutting device 1 according to the embodiment, when the continuous wave body 8 is cut by the first cutting blade 20 and the second cutting blade 45 even when the outer gear 30 rotates at a relatively high speed, the first cutting blade 20 Since the position of and the position of the opening 300 can be made the same, the continuous wave body 8 can be cut to a desired length at high speed and with high accuracy.

  In the cutting device 1 according to the embodiment, the outer restraint gear 40 has the restraining outer teeth 41 that mesh with the inner teeth 42 of the outer gear 30 only when the first cutting blade 20 protrudes from the opening 300. Thereby, when the inner teeth 42 and the restraining outer teeth 41 mesh with each other, the rotation of the first cutting blade support portion 25 that rotates integrally with the outer restraining gear 40 and the rotation of the outer gear 30 can be reliably synchronized. Accordingly, in one embodiment, the continuous wave body 8 can be reliably cut to a desired length.

  In the cutting device 1 according to the embodiment, the outer restraint gear 40 is provided on the shaft 26 that rotatably supports the first cutting blade support portion 25. As a result, the rotation of the outer restraint gear 40 and the first cutting blade support portion 25 becomes the same, and therefore the rotation of the outer gear 30 and the rotation of the first cutting blade support portion 25 when the inner teeth 42 and the restraining outer teeth 41 mesh. The rotation can be reliably synchronized. Accordingly, in one embodiment, the continuous wave body 8 can be reliably cut to a desired length.

(Other embodiments)
In the above-described embodiment, the first cutting blade has the blade portion, the connection portion, and the engagement portion. The second cutting blade has a blade portion, a connection portion, a contact portion, and a cam follower. However, the configuration of the first cutting blade and the second cutting blade is not limited to this. The 1st cutting blade should just be provided in contact with a continuous wave-like object. The second cutting blade is provided so as to be able to contact the second surface opposite to the first surface of the continuous wave-like body, and can cut the continuous wave-like body by contacting the continuous wave-like body together with the first cutting blade. That's fine.

  In the above-described embodiment, the outer gear has nine openings. However, the number of openings is not limited to this. The number of openings is set according to the length of the corrugated fin cut out from the continuous wave-like body. Therefore, the number of openings may be one, and it is only necessary that the first cutting blade can protrude from the one opening when the outer gear and the outer restraining gear mesh with each other.

  In the above-described embodiment, the outer restraint gear has the restraining outer teeth that can mesh with the inner teeth of the outer gear. However, the teeth on the outer gear side that can mesh with the restraining outer teeth are not limited to the inner teeth.

  In the above-described embodiment, the outer restraint gear is provided on the radially outer side of the rotating body, and can rotate integrally with the shaft and the rotating body. However, the position where the outer restraint gear is provided is not limited to this. What is necessary is just to be able to rotate synchronizing with rotation of a 1st cutting blade support part.
