(1st cutting mechanism 38)

12 to 17, the rail 93 in the first cutting mechanism 38 extends in a direction orthogonal to the loading and unloading direction of the workpiece 36 on the base 31a of the frame 31. It is arranged. The movable table 94 is movably supported on the rail 93, and a pair of guide rods 95 protrude from the upper surface thereof. The moving cylinder 96 as the first cylinder constituting the biasing means is mounted on the base 31a of the frame 31 via the bracket 97, and the piston rod 96a is connected to the movable table 94. have.

Then, the moving table 94 is moved in the direction of approaching or separating the work piece 36 on the clamp mechanism 37 by the protruding or immersing operation of the moving cylinder 96. In addition, in the state in which the movable table 94 approaches and moves toward the work piece 36, the rotary cutter 111 to be described later passes the center of rotation of the work piece 36 with respect to the outer circumference of the work piece 36. Pressing is deflected with a predetermined force in the first direction D1 (see FIG. 16).

The rack 98 is protruded from the movable table 94 so as to extend along the movement direction thereof. The encoder 99 as the detection means is attached to the bracket 97, and the pinion 100 engaged with the rack 98 is attached to the detection shaft. Then, the pinion 100 is rotated through the rack 98 when the movable stand 94 is moved during the chamfering of the workpiece 36.

Accordingly, a detection signal relating to the distance from the rotation center of the workpiece 36 to the rotary cutter is output from the encoder 99 to adjust the rotation speed of the workpiece 36 by the workpiece rotation motor 73. . That is, for example, when the moving table 94 is moved away from the rotation center of the work piece 36 at the time of processing such as a corner of the work piece 36, the work piece is rotated according to the detection signal from the encoder 99. The rotation speed of the motor 73 is lowered. By doing in this way, the periodic speed of the workpiece | work 36 in the joining position of the rotary cutter 111 is kept constant.

The lifting platform 101 is supported by the guide rod 95 of the movable table 94 to be liftable. The lifting cylinder 102 is disposed on the moving table 94, and the piston rod 102a is connected to the lifting table 101.

The contact roller 112 is supported at the lower end of the cutter shaft 109 so as to be relatively rotatable through a plurality of bearings 113. Then, when the movable table 94 moves closer to the workpiece 36 on the clamp mechanism 37 by the protruding motion of the moving cylinder 96, the contact roller 112 contacts the outer peripheral surface of the workpiece 36. Thus, the rotary cutter 111 is disposed opposite to the predetermined position of the outer circumference of the workpiece 36.

The contact cylinder 114 is attached to the lower surface of the distal end of the swinging arm 106 so as to surround the rotary cutter 111. Then, when the lifting platform 101 is lowered by the immersion operation of the lifting cylinder 102 while the contact roller 112 is in contact with the outer circumferential surface of the workpiece 36, the lower end of the contact cylinder 114 is In contact with the upper surface of the work piece 36, the rotary cutter 111 is disposed at a predetermined position of the upper edge of the circumference of the work piece 36.

Then, the swinging arm 106 oscillates through the rack 122 and the pinion 105 by the oscillating motion of the swinging cylinder 121, and the rotation cutter 111 with respect to the outer circumference of the workpiece 36 is moved. The corresponding position is changed in the direction crossing the moving direction of the movable table 94. In addition, as shown in Fig. 16, in the projecting operation state of the swinging cylinder 121, the rotary cutter 111 is predetermined in the second direction D2 crossing the first direction D1 with respect to the outer circumference of the workpiece 36. Pressing is biased by force. In addition, the pressing direction D2 of the rotary cutter 111 by the cylinder 121 is a direction opposite to the rotation direction of the workpiece 36 at the contact position with the workpiece 36.

In the operation of the device, the swinging cylinder 121 is projected by a predetermined force, and as shown in FIG. 17, the tip of the rack 122 fixed to the piston rod 121a has a positioning screw attached to the lifting table 101. As shown in FIG. (124). In this state, as shown by the solid line in FIG. 16, the rotation center of the rotary cutter 111 is arrange | positioned on the line which passes the rotation center of the workpiece | work 36 and the rotation center of the oscillation shaft 103. As shown in FIG. In this state, the rotary cutter 111 is usually pressed against the outer circumference of the workpiece 36 by the moving cylinder 96 in the first direction D1 in this state. In this state, if a force greater than the pressing power of the swinging cylinder 121 to the rotary cutter 111 acts in the opposite direction to the second direction D2, the cylinder 121 is immersed and the rotary cutter 111 is depressed. At the position indicated by the solid line of 16, it moves in the direction indicated by the dotted line.

The position detection sensor 123 is attached to the outer surface of the swinging cylinder 121. This sensor 123 is for detecting the position of the piston 121b of the cylinder 121. And when the rotary cutter 111 oscillates in the direction shown by the dotted line at the position shown by the solid line of FIG. 16, in other words, when the cylinder 121 is immersed in the state shown in FIG. The position change of 121b is detected, and the pressing of the rotary cutter 111 by the said moving cylinder 96 to the 1st direction D1 is cancelled | released. That is, the rotary cutter 111 is always pressed in the first direction D1 by the moving cylinder 96, but may not be fully bounced in the opposite direction to the first direction D1 depending on the contact angle with the workpiece 36. . However, if the pressing by the moving cylinder 96 is canceled by the rocking | fluctuation along the 2nd direction D2 of the rotary cutter 111 like this embodiment, the rotary cutter 111 will be smooth in the direction opposite to the 1st direction D1. I can move it.

As described above, the work piece is normally pressed by the moving cylinder 96 and the swinging cylinder 121 in the first direction D1 and the second direction D2 toward the outer circumference of the work piece 36. The chamfering process is performed to the outer periphery edge of (36). When the load on the rotary cutter 111 changes during this chamfering operation, the moving table 94 is moved along the first direction D1 or the swinging arm 106 is swinged along the second direction D2 to rotate the cutter. The 111 is smoothly joined to the outer periphery of the work piece 36.

(Work export mechanism 40)

As in FIG. 3, the workpiece | work carrying out mechanism 40 is comprised substantially the same as the workpiece | work taking-in mechanism 34 mentioned above. Then, the processed work piece 36 is sucked and supported by the adsorption plate 52 provided with the plurality of electromagnets 56 to be carried out from the processing position P2 to the carrying out position P3, and laminated on the carrying table 41. do.

Next, operation | movement of the edge processing apparatus comprised as mentioned above is demonstrated.

First, in the edge processing apparatus, the large number of workpieces 36 stacked on the carry-on stand 35 at the carry-in position P1 are supported by the work-loading mechanism 34 one by one and brought into the machining position P2. And the lower clamp body 71 of the clamp mechanism 37. In this state, the workpiece 36 is clamped between the upper clamp body 86 and the lower clamp body 71 of the clamp mechanism 37, and is rotated in a vertical axis cycle by the workpiece rotation motor 73. .

And the rotary cutter 111 of the 1st cutting mechanism 38 and the rotary cutter 129 of the 2nd cutting mechanism 39 are joined by the both sides with respect to the outer periphery of the workpiece | work 36 on this clamp mechanism 37, The moving cylinder 96 and the swinging cylinder 121 are pressed by a predetermined pressing power. As a result, the joining positions of the rotary cutters 111 and 129 of the two cutting mechanisms 38 and 39 with respect to the workpiece 36 are shifted in accordance with the change in the outer circumferential shape of the workpiece 36. Chamfering is carried out at the upper periphery and the lower periphery of (36).

When the chamfering process for the workpiece 36 is finished in this manner, the rotary cutters 111 and 129 of the two cutting mechanisms 38 and 39 are separated from the outer periphery of the workpiece 36 and clamped. The clamp of the workpiece 36 by the mechanism 37 is opened. Thereafter, the finished workpiece 36 is sucked and supported by the workpiece discharging mechanism 40 to be unloaded from the machining position P2 to the discharging position P3, and laminated on the discharging stand 41.

The effect which can be expected by the above-mentioned embodiment is as follows.

(a) In the edge processing apparatus of this embodiment, the workpiece | work 36 is rotated by the workpiece | work rotation motor 73 by the period of one vertical axis in the state clamped by the clamp mechanism 37. As shown in FIG. Then, the rotary cutters 111 and 129 of the cutting mechanisms 38 and 39 are pressed and joined to the outer circumference of the workpiece 36 to chamfer. Therefore, even when the workpiece 36 is small or the outer circumferential shape of the workpiece 36 is complicatedly changed, the joining positions of the rotary cutters 111 and 129 with respect to the workpiece 36 are smoothly displaced. The chamfering process can be performed easily in a short time, without requiring an expert on the outer periphery of the workpiece 36.

(b) In the edge processing apparatus of this embodiment, the workpiece 36 is provided by the moving cylinder 96 which is the first cylinder with respect to the rotary cutters 111 and 129 joined to the outer periphery of the workpiece 36. The pressing power is imparted in the first direction D1 passing through the rotational center of. At the same time, the pressing power is applied to the rotary cutters 111 and 129 by the swinging cylinder 121 serving as the second cylinder in the second direction D2 crossing the first direction D1. Accordingly, whatever the outer circumferential shape of the work piece 36 is, the rotary cutters 111 and 129 rotate in the first direction D1 and the first direction with respect to the outer circumference of the work piece 36 in accordance with the rotation of the work piece 36. The joint positions of the rotary cutters 111 and 129 are displaced while being foldable freely in two directions D2. Therefore, the chamfering process can be easily and continuously performed along the outer periphery of the workpiece 36.

(c) In the edge processing apparatus of this embodiment, while the workpiece 36 is rotated at a period of one vertical axis, chamfering is performed on the outer circumferential edge of the workpiece 36 by the first cutting mechanism 38. The chamfering process is performed to the outer periphery lower edge of the workpiece | work 36 by the 2nd cutting mechanism 39. FIG. Therefore, the chamfering process can be performed efficiently with respect to the outer periphery upper edge and the outer periphery lower edge of the workpiece | work 36 at the same time. Moreover, the 1st and 2nd cutting mechanisms 38 and 39 can also operate independently.

(d) In the edge processing apparatus of this embodiment, the distance from the rotation center of the workpiece 36 to the rotary cutters 111 and 129 is detected by the encoder 99 as the detection means, and the detection result Accordingly, the rotational speed of the workpiece 36 by the workpiece rotation motor 73 is adjusted. Therefore, even when the outer circumferential shape of the work piece 36 is greatly changed, the periodic speed of the work piece 36 at the joining position of the rotary cutters 111 and 129 is kept constant and chamfering with uniform cutting conditions. You can do In addition, when red-machining is performed simultaneously in both the 1st and 2nd cutting mechanisms 38 and 39, the distance from the rotation center of the workpiece | work 36 to the rotary cutters 111 and 129 is larger. By adjusting the rotational speed of the motor 73 in accordance with the detection result, the cycle speed of the work piece 36 at the joining position of the rotary cutters 111 and 129 can be made within a predetermined value, so that good cutting can be performed. have.

(e) In the edge processing apparatus of this embodiment, the raw workpiece 36 is carried on the clamp mechanism 37 by the workpiece loading mechanism 34, and the finished workpiece 36 is the workpiece. The carrying out mechanism 40 is carried out on the clamp 37. Thus, the loading and unloading of the workpiece 36 can be performed automatically, so that the overall processing time including the loading and unloading of the workpiece 36 can be shortened even more.

(f) In the edge processing apparatus of this embodiment, the rotary cutters 111 and 129 are biased by a predetermined force in a vertical force with respect to the outer periphery of the workpiece 36 by the lifting cylinder 102. have. Therefore, even if the upper and lower surfaces of the workpiece 36 are displaced in the vertical direction, the rotary cutters 111 and 129 reliably follow the outer periphery of the workpiece 36 as the workpiece 36 rotates. Since it is moved, the chamfering processing can be performed more reliably.

(g) In the edge processing apparatus of the present embodiment, the rotary cutters 111 and 129 swing in the opposite direction to the second direction D2, which is the pressing direction by the swinging cylinder 121, so that the moving cylinder 96 Pressing in the first direction D1 is canceled by. Accordingly, the rotary cutters 111 and 129 can move smoothly in the direction opposite to the first direction D1, and the rotary cutters 111 and 129 work even when the workpiece 36 is formed in any shape. It reliably follows the outer periphery of the water 36.

(h) In the edge processing apparatus of this embodiment, the upper support frame 31b for suspending the upper mechanism of the workpiece | work carrying-in mechanism 34, the workpiece | work carrying-out mechanism 40, and the clamping mechanism 37 is the base ( It is installed obliquely on 31a). Specifically, the upper support frame 31b passes over the machining position P2 (the position corresponding to the clamp mechanism 37) and the loading and unloading direction of the workpiece 36 (the workpiece loading and unloading mechanisms 34, 40). 2 legs 311 are provided on the base 31a so as to be inclined at an angle with respect to the direction of movement). That is, for example, when the upper support frame is supported with four legs on the base 31a, the machining position P2 is surrounded by the support frame. In this case, it becomes difficult for an operator to perform maintenance or the like at the machining position P2. On the other hand, since the upper support frame 31b of this embodiment does not air-wrap the machining position P2, an operator can easily perform maintenance etc. at the machining position P2. In addition, the structure of the support frame 31b becomes simple. In addition, the upper support frame 31b provided with the two legs 311 is inclined with respect to the carrying-in / out direction of the work piece 36, so that it does not interfere with the work carrying-in mechanism 34 and the work taking-out mechanism 40. FIG. Therefore, the legs 311 of the upper support frame 31b are not disturbed at the time of carrying in and out of the workpiece 36 by the carrying in mechanism 34 and the carrying out mechanism 40.

In addition, this invention can also be embodied by changing as follows.

(1) The structure of the workpiece | work carrying-in mechanism 34, the clamp mechanism 37, the 1st cutting mechanism 38, the 2nd cutting mechanism 39, and the workpiece | work carrying-out mechanism 40 was changed suitably.

(2) The one of the 1st cutting mechanism 38 and the 2nd cutting mechanism 39 is abbreviate | omitted.
