  As shown in FIG. 10, the CVT element cutting device according to the prior art includes an air cylinder connected to a speed controller. The air cylinder is controlled by a speed controller so that the rod protrudes downward and the rod moves up and down, and a slide cam is disposed at the tip of the rod.

  A slider bracket projects downward from the lower part of the air cylinder, and a slider support member projects rightward from the upper and lower central portions of the slider bracket. The slider is slidably disposed in the horizontal direction through the slider bracket, the slider support member, and the linear guide disposed on the slider support member.

  A cam follower is rotatably disposed at one end on the slide cam side of the slider, and a cut-out holder having a groove formed on the lower surface is disposed at the other end. The cutting holder is connected to the lower end of the slider bracket by a tension spring, and the cam follower is disposed in contact with the slide cam. That is, the cam follower, the slider, and the cutting holder always receive a tensile force in the direction of the slide cam by the tension spring.

  The rod is moved up and down by the air cylinder, so that the slide cam slides the cam follower, slider, and cutting holder in the horizontal direction. FIG. 10 shows a state in which when the air cylinder pulls the rod upward (in the direction of arrow α in FIG. 10), the cutting holder moves horizontally in the direction opposite to the cylinder cam (in the direction of arrow β in FIG. 10). ing.

  Below the cutting holder, an element guide having a substantially concave cross section is disposed. The element guide communicates with the bottom surface so that the CVT element can pass through the portion where the groove formed in the cutting holder is located when the cutting holder is located farthest from the slide cam by sliding of the slider. An opening is provided. In other words, when the cutting holder is located farthest from the slide cam, the groove of the cutting holder and the opening of the element guide are configured to coincide with each other.

  As shown in FIG. 11, the element guide is formed with an element supply portion extending rearward, and the CVT elements are aligned and fed along the element supply portion in the direction of arrow γ in FIG. That is, the CVT element is fed forward in order along the element supply portion and supplied to the groove portion of the cutting holder. Each time the cutting holder slides in the horizontal direction by driving the air cylinder, it is configured to fall one by one below the element guide from the opening.

A comb-like alignment jig whose longitudinal direction is directed to the left and right is disposed below the element guide, and is configured to advance by a predetermined width in synchronization with the vertical movement of the air cylinder. That is, the CVT elements dropped through the opening of the element guide are arranged in order on the alignment jig one by one.
With such a CVT element cutting device, the CVT elements are aligned on an alignment jig and then quenched.

  According to the prior art, as described above, the vertical movement of the slide cam by the air cylinder is converted into the horizontal movement of the cutting holder. However, the drive speed of the air cylinder may change depending on the change in atmospheric pressure or the air consumption of the devices connected to the surroundings. For this reason, it is structurally unsuitable for high-speed and high-frequency use, and it has been difficult to improve the CVT block cutting efficiency. Further, since the cutting holder repeats minute movements with a width of about 4 mm, the balls inside the linear guide may not be sufficiently circulated and may be unevenly worn, and the original durability may not be exhibited.

  Further, when the CVT elements are not continuously supplied and the supply interval is large, the CVT elements may be bitten.

A collision with the stopper surface occurs. At that time, the element confirmation sensor installed at the position of point b detects the presence of the element, and the cutting by the cutting holder is started.

Here, when the CVT element is continuously supplied, it does not rebound because it abuts on an adjacent (next supplied) CVT element, but when it is supplied alone as shown in FIG. It rebounds in the direction of arrow c in FIG. At this time, since the cutting holder has already started cutting as described above, the CVT element is caught between the element supply portion and the cutting holder at the position d in FIG. Will occur.
When the CVT element bites in this way, the CVT element may be bent. In this case, the time until the CVT block is removed by disassembling the device is greatly lost, and the cutting efficiency is reduced. Was supposed to make it worse.

  In order to prevent the biting, a method of adhering an impact absorbing material such as a urethane material to the stopper surface of the element guide can be considered. However, since the stopper surface comes into contact with the CVT element every time it is cut out, it is difficult to put it to practical use because of early wear and increased frictional force at the time of cutting. Met. Furthermore, since the CVT element has a small mass, it is pushed back after absorbing the shock, and its effectiveness is insufficient to prevent biting.

That is, by driving the motor 21, the camshaft 22, the cam 23, and the mechanical valve cam 23a are oriented in the front-rear direction (direction perpendicular to the longitudinal direction of the apparatus base 11) in the direction of the arrow R in FIG. It is comprised so that it may rotate.

  On the other hand, the CVT element cutout portion 30 is disposed in the CVT element cutout portion side guide case 11c. Specifically, the cut base 37 is disposed on the upper surface of the CVT element cut portion side guide case 11 c, and the cut bracket 36 is erected upward from the upper surface of the cut base 37. A link support member 35 is disposed on the upper surface of the cut-out bracket 36, and the cam follower 32 is rotatable at the left end via a left link 33 and a right link 34 that are rotatably supported by the link support member 35. The cut-out holders 31 (the left-side cut-out holder 31a and the right-side cut-out holder 31b) provided in the above are disposed. Further, element guides 41 (left element guide 41a and right element guide 41b) are disposed on the upper surface of the cut base 37 and below the cut holder 31.

  The motor base 25 and the cut base 37 receive a mutual tensile force by being connected by a tension spring 61. In a normal state, the motor drive unit 20 and the CVT element cut unit 30 are connected to each other. The relative distance is constant.

[CVT element cutout 30]
In the CVT element cutout portion 30, the cutout holder 31 is configured by connecting a left cutout holder 31a and a right cutout holder 31b as shown in detail in a partially cutaway front view of FIG. A groove 31c is formed between the left-side cut holder 31a and the right-side cut holder 31b. That is, the cut-out holder 31 is configured as an inverted concave member, and the CVT element E is supplied to the groove 31c. is there.

A cam follower 32 is rotatably disposed at a left end portion of the left cut-out holder 31 a, and the cam follower 32 is in contact with the cam 23. In addition, the substantially lower left and right central lower portions of the left-side cutting holder 31a are connected to the left end portion of the link support member 35 by the left link 33 so as to be relatively rotatable.
On the other hand, the lower right end portion of the right cut holder 31b is connected to the middle portion of the link support member 35 by the right link 34 so as to be relatively rotatable. That is, the cutting holder 31 is supported by the left link 33 and the right link 34 so as to be pivotable at two points on the left and right, and is arranged so as to be swingable left and right.

  The right link 34 has an extension 34 a formed above the support to the link support member 35, and the extension 34 a is connected to the link support member 35 with a bolt via a tension spring 42. That is, the extending portion 34a always receives a pulling force to the right side, whereby the cutting holder 31 is biased to the left side, that is, in the direction of the cam 23. With such a configuration, the cam follower 32 follows the rotation of the cam 23, and the cutting holder 31 is configured to swing left and right by the rotation of the cam 23.

  The element guide 41 is configured by connecting a left element guide 41a and a right element guide 41b. As shown in FIG. 1, the right element guide 41b is formed so as to block the groove 31c portion on the front surface of the cutting holder 31, and as shown in FIG. 3, the CVT element E supplied to the groove 31c from the rear is the right element guide. It is comprised so that it may contact | abut and stop at 41b. In front views of FIG. 2 and subsequent figures, the front side portion of the right element guide 41b is omitted for convenience of explanation.

  As shown in FIGS. 2 and 4, an opening 41c is formed between the left element guide 41a and the right element guide 41b. Specifically, when the cutting holder 31 is located farthest from the cam 23 by the rotation of the cam 23, the groove 31 c formed in the cutting holder 31 is communicated with the bottom surface of the element guide 41. The opening 41c is formed. In other words, the element guide 41 is disposed so that the groove 31c of the cutting holder 31 and the opening 41c of the element guide 41 coincide with each other when the cutting holder 31 is located farthest from the cam 23. (See FIG. 5).

  Further, as shown in FIG. 3, an element supply part 41d extends rearward from the element guide 41, and the CVT element E is aligned along the element supply part 41d in the direction of arrow C in FIG. And pumped. That is, the CVT element E is sent forward in order along the element supply part 41 d and supplied to the groove part 31 c of the cutting holder 31. Then, as shown in FIG. 3, the CVT element E comes into contact with the right element guide 41 b and stops, and as shown in FIG. 5, every time the cutting holder 31 swings to the right side by the rotation of the cam 23. In addition, it is configured to fall one by one below the element guide 41 from the opening 41c.

  Thus, in this embodiment, since the rotation of the cam 23 due to the drive of the motor 21 is converted into the swing of the cutting holder 31, the drive speed does not change as in the conventional air cylinder. , Reliability during high-speed and high-frequency use can be improved. In addition, since the linear guide is not used for swinging the cutting holder 31, there is no occurrence of uneven wear of the ball, and sufficient durability can be exhibited.

Below the element guide 41, a comb-like alignment jig 51 whose longitudinal direction is directed to the left and right is disposed, and is configured to advance rightward by a predetermined width in synchronization with the rotation of the cam. Is done. That is, the CVT elements E dropped from the opening 41c of the element guide 41 are arranged in order on the alignment jig 51 one by one.
In the present embodiment, the CVT element cutting device 10 configured as described above is used to perform quenching after aligning the CVT element E with the alignment jig 51.

  As described above, the CVT element cutting method according to the present embodiment includes a CVT element supply step in which the CVT element E is continuously pumped and supplied to the CVT element cutting portion 30 disposed on the apparatus base 11. In the motor drive unit 20 disposed adjacent to the CVT element cutout 30 on the apparatus base 11, the cam 23 is rotated by the drive of the motor 21, and in the CVT element cutout 30, the cam A CVT element cutting step of dropping the CVT element E supplied into the cutting holder 31 by swinging the cutting holder 31 provided with a cam follower 32 following the head 23 by the rotation of the cam 23; Along the longitudinal direction of the apparatus base 11, the arrangement is arranged below the CVT element cutout 30. The jig 51, the aligning cutting the CVT element E which has fallen by the swinging of the holder 31 is to comprise an alignment step.

[Shock absorber]
In this embodiment, as shown in FIGS. 2 and 3, a urethane material 38 is bonded to the cutout holder 31 as an impact absorbing material on the inner upper surface of the groove 31c.
With this configuration, even when the CVT element E is not continuously supplied and the supply interval is large, the biting of the CVT element E can be reduced.
Specifically, when the CVT element E is supplied continuously (single unit) in the element supply unit 41d, a collision occurs with the stopper surface 41e of the right element guide 41b at a point D shown in FIG. At that time, the element confirmation sensor installed at the position of the point D detects the presence of the CVT element E, and the cutting by the cutting holder 31 is started.

  Here, a clearance of a predetermined dimension is provided between the upper end of the CVT element E supplied to the cutting holder 31 and the inner upper bottom surface of the groove portion 31c (strictly, the lower surface of the urethane material 38). The center of gravity of the CVT element E is higher than the point D, which is the collision point between the CVT element E and the stopper surface 41e. Therefore, as shown in FIG. It rotates toward the front upper side around the vicinity (in the direction of arrow r in FIG. 6). The urethane material 38 absorbs the impact of the CVT element E by coming into contact with the urethane material 38 adhered to the inner upper bottom surface of the groove 31c. For this reason, the CVT element E does not rebound to the element supply part 41d side, and the CVT element E is sandwiched between the right element guide 41b and the cutting holder 31 even when the cutting holder 31 starts cutting. To prevent this. In particular, even when the cutting holder 31 is swung at a high speed and a high frequency by driving the motor 21 as in the present embodiment, the occurrence of the biting of the CVT element E can be effectively prevented. .

Further, the urethane material 38 does not come into contact with the CVT element E when it is normally cut out, that is, when the CVT element E is continuously supplied, and is not abraded. Further, the urethane material 38 is bonded to the inner upper bottom surface of the groove 31c, and frictional force with other members is not generated at the time of cutting, so that biting can be effectively prevented.
The impact absorber is not limited to a material made of urethane, and may be any material having plasticity such as a resin material, and is not limited to the present embodiment.

[Air pusher 64]
In the present embodiment, as shown in FIG. 1, an air pusher 64 for accelerating the dropping speed of the CVT element E is disposed in the cutting holder 31, and the motor 21 in the motor driving unit 20 is disposed in the motor 21. A mechanical valve 62 connected to the air pusher 64 is provided, and the opening and closing of the mechanical valve 62 is synchronized with the cam 23 to control the driving of the air pusher 64.

  Specifically, the mechanical valve 62 is connected to an air pipe 63a that supplies air from an air pump (not shown) in the direction of arrow IN in FIG. The mechanical valve 62 and the air pusher 64 are connected by an air pipe 63b that supplies air in the direction of the arrow OUT in FIG.

  As shown in FIGS. 2 and 3, two air pushers 64 are arranged on the upper surface of the left-side cut-out holder 31a and above and behind the groove 31c. A communication hole 31d that penetrates from the upper surface to the groove 31c is opened at each location in contact with the air pusher 64 in the right-side cutting holder 31b, and a hole is also opened at the same location in the urethane material 38. . That is, the air sent from the air pipe 63b is jetted into the groove 31c by the air pusher 64 and blown onto the CVT element E, so that the falling speed of the CVT element E is forcibly increased. .

  On the other hand, the mechanical valve 62 is connected to a mechanical valve cam follower 65, and is configured to open when the mechanical valve cam follower 65 is pushed upward by the rotation of the mechanical valve cam 23a. In this embodiment, as shown in FIG. 7, the mechanical valve cam 23 a has a 90 ° phase with respect to the cam 23 in the direction opposite to the rotation direction of the cam 23 (the direction of the arrow R in FIG. 7). Are arranged in a shifted manner. The mechanical valve cam follower 65 is disposed 90 degrees out of phase with respect to the cam 23 in the direction opposite to the direction of rotation of the cam 23 from the cam follower 32 (the direction of arrow R in FIG. 7).

That is, the cutting start timing of the cutting holder 31 when the cam 23 pushes the cam follower 32 to the right side, and the air supply timing of the air pusher 64 when the mechanical valve cam 23a pushes the mechanical follower cam follower 65 upward. By synchronizing, air is injected at the moment when the CVT element E drops, and the CVT element E can be dropped efficiently.
The phase difference between the cam 23 and the mechanical valve cam 23a, the swing distance of the cutting holder 31, and the like can be arbitrarily set. In other words, the relationship between the cutting start timing of the cutting holder 31 and the air supply timing of the air pusher 64 can be freely adjusted and changed, and is not limited to this embodiment.

[Tension spring 61]
In the present embodiment, as shown in FIG. 1, the motor drive unit 20 and the CVT element cutout unit 30 can slide on the apparatus base 11 via the same guide rail 11a. And are coupled in a state of being attracted to each other via a tension spring 61.

  Specifically, the motor base side guide case 11b slidably arranged in the left and right directions, the motor base 25 provided on the CVT element cutout side guide case 11c, and the cutout base 37, respectively. Are connected to each other by a tension spring 61, so that they are mutually subjected to a tensile force, and in a normal state, the relative distance is constant.

With the configuration described above, if the CVT element E is caught between the right element guide 41b and the cutting holder 31 (see FIG. 12C), the motor drive unit 20 Can be retracted to the side (left side) opposite to the CVT element cutout 30.
Specifically, when the CVT element E is bitten, the cutting holder 31 cannot follow the rotation of the cam 23, so that the cam 23 and the motor drive unit 20 are moved to the left side by the reaction force from the cam follower 32. It will receive the power toward. As the tension spring 61 is extended by this reaction force, the motor drive unit 20 moves to the left side together with the motor drive unit side guide case 11b as shown in FIG. 8 (the two-dot chain line in FIG. The position of the motor drive unit 20 is shown).

With such a configuration, even when the CVT element E is caught between the right element guide 41b and the cutting holder 31, the CVT element E is bent so as to be bent. Damage can be avoided. That is, when the biting occurs, the motor drive unit 20 is retracted to the left side, so that a large force that causes the CVT element E to be bent is not applied.
As a result, the CVT element cutting device 10 is not disassembled and the CVT element E is not eliminated, so that it is possible to prevent the cutting efficiency from deteriorating due to a large loss of time for repair.

  In the present embodiment, the CVT element cutting device 10 may be provided with a mechanism for raising and lowering the entire unit. Specifically, lift levers that can be operated manually or automatically are provided at both left and right ends of the apparatus base 11 or left and right ends of a support member that supports the bottom surface of the motor 21 and extends left and right. By doing so, the CVT element cutting device 10 is moved up and down as a whole unit.

  By configuring in this way, when the CVT element E falls on the alignment jig 51, the CVT element E is not properly dropped, for example, even when it is dropped obliquely or sideways. It becomes easy to re-align properly. That is, by raising the CVT element cutting device 10 as a whole unit as described above, a space can be secured in the vicinity of the alignment jig 51. Therefore, it is easy for the operator to properly align the CVT element E. It becomes. Thereby, the measure when the CVT element E becomes a drop defect is simplified, and the efficiency of the cutting work can be improved.

[Adjacent CVT element cutting device 110]
Further, in this embodiment, as shown in FIG. 9, it is possible to arrange adjacent CVT element cutting devices 110 of different vehicle types in addition to the CVT element cutting device 10. Specifically, the motor drive unit side guide case 111b and the CVT element cutout side guide case 111c are slidably disposed on the guide rail 11a in the CVT element cutout device 10 and slidable to the left and right respectively. A motor driving unit 120 and a CVT element cutting unit 130 configured in the same manner as the cutting device 10 are disposed. The adjacent CVT element cutting device 110 is connected and fixed to the CVT element cutting device 10 by sharing the cutting base 37 and the link support member 35 in the CVT element cutting device 10. In other words, the adjacent CVT element cutting device 110 is connected to the CVT element cutting device 10 through the cutting base 37 and the link support member 35 so as to form a bilaterally symmetric shape, and is integrally left and right along the guide rail 11a. It is slidably disposed on the surface.

  In the present embodiment, a step change hole 37 a penetrating in the vertical direction is opened in the rear left and right central portion of the cutout base 37. In addition, at the rear of the upper surface of the apparatus base 11, step fixing fixing holes 11 d and 111 d are opened one by one at left and right positions from the center. When the CVT element cutting device 10 is driven, as shown in FIG. 9A, a changeover pin 71 is made to penetrate the changeover hole 37a and is opened on the right side of the device base 11. 11d is inserted, and the CVT element cutting device 10 and the adjacent CVT element cutting device 110 are fixed.

  When the adjacent CVT element cutting device 110 is driven, the changeover pin 71 is pulled upward, and the CVT element cutting device 10 and the adjacent CVT element cutting device 110 are moved in the direction of the arrow S in FIG. As shown in FIG. 9B, the changeover pin 71 is passed through the changeover hole 37a and inserted to the changeover fixing hole 111d opened on the left side of the apparatus base 11, and the CVT element cutting device 10 is moved. And the adjacent CVT element cutting device 110 is fixed.

  Even if the CVT element cutting device 10 and the adjacent CVT element cutting device 110 are moved as described above, the element supply line position F located behind the element supply portion 41d does not move. It is possible to change the stage to the dispensing device 110. In other words, it is possible to easily change the vehicle type by simply attaching / detaching the changeover pin 71 and sliding the CVT element cutting device 10 and the adjacent CVT element cutting device 110.
