A loader unit 2a for supplying the chuck to be attached to the chuck of the cleaning device 200 and an unloader unit 2b for recovering the workpiece 100 removed from the chuck after the ultrasonic cleaning is provided.

  FIG. 1 is a perspective view of a main part of a loader / unloader apparatus 2 as an example of the present invention, FIG. 2 is a plan view of the loader / unloader apparatus 2, and FIG. A side view of the loader device 2 is shown, and FIG. 4 shows another side view. It should be noted that the loader unit 2a and the unloader unit 2b are each independently referred to as the loader / unloader device of the present invention, and the unloader unit 2b basically has the same configuration as the loader unit 2a. In the description, the loader unit 2a will be mainly described, and thereafter, the unloader unit 2b will be described only with respect to differences from the loader unit 2a.

  As shown in FIGS. 1 and 2, the loader unit 2 a is disposed between the transfer unit 102 on which the workpiece 100 is continuously transferred and the chuck mounting portion 202 of the cleaning device 200. The transfer unit 102 is a unit that transfers the conveyed workpiece 100 to the table 26 that is a workpiece holding unit of the loader unit 2a. The transfer unit 102 includes a transfer approach section 122 that is close to the table 26 of the loader unit 2 a along the direction in which the workpiece 100 is transported by the transport conveyor 104, and a transfer separation section 124 that is separated from the table 26.

And a plurality of workpiece transfer members 130 that are capable of rotating along the conveying direction of the workpiece 100 and that are trajectory controlled by the annular cam 120 and are slidably movable with respect to the table 26. .

  The rotation trajectory of the workpiece transfer member 130 is an elliptical trajectory around the horizontal axis. In the lower trajectory of the elliptical trajectory, the approach section 122 and the separation section 124 of the annular cam 120 are directed to a line directed to the table 26 side. The sliding movement is controlled so that the workpiece 100 can be continuously pushed out to the table 26 side and transferred to the table 26.

  According to the transfer unit 102, the individual workpieces 100 conveyed can be transferred continuously to a predetermined transfer destination. Further, since the individual workpiece transfer members 130 are continuously trajectory controlled by the annular cam 120 and the slide range is controlled so that they can be pushed out and retracted, the transfer processing time per workpiece 100 can be easily shortened. it can.

  The loader unit 2a includes a rotating unit 10 that is rotationally driven on an elliptical track by a driving device (not shown) and a timing belt, and a workpiece supply member that is supported by the rotating unit 10 so that the elliptical track can rotate and can be moved up and down. 20a and an annular cam 40 that controls the lifting and lowering of the workpiece supply member 20a on the elliptical track.

  The rotation unit 10 can supply the table 26 which is a workpiece holding part of the workpiece supply member 20a to the transfer site 103 so that the workpiece 100 transferred from the conveyor can be received by the transfer unit 102, and the cleaning device 200. The table 26 is disposed at a predetermined height so that the table 26 can be supplied to the chuck mounting portion 202. The rotating unit 10 includes two sprocket wheels 12 that are rotationally driven and an endless block chain 14 that is suspended between the sprocket wheels 12. With such a configuration, the rotating unit 10 has an elliptical orbit around the vertical axis, the long side portion of one straight line of the elliptical track faces the transfer unit 102, and the long side portion of the other straight line is the cleaning device. It is arranged to correspond to 200 chuck mounting parts 202.

  The workpiece supply member 20 a includes a table 26 on which the workpiece 100 is placed, which is rotatably held by the rotary unit 10. The table 26 only needs to be able to place the workpiece 100 so as to be pressed against the chuck mounting portion 202 of the cleaning device 200. In order to hold the workpiece 100 stably, a wall body 26a may be provided. In addition, the member holding the workpiece | work 100 is not limited to the table 26, What is necessary is just an appropriate thing according to the loading / unloading form other than the kind and magnitude | size of the workpiece | work 100. FIG.

The table 26 is fixed to each block unit 15 of the block chain 14 as shown in FIGS. In this embodiment, the table 26 is fixed to the cylinder 22 fixed to the block unit 15 and the upper end of the rod 23 attached to the piston 22a of the cylinder 22. When the rod 23 is driven by the cylinder 22 and the piston 22a, a pressure of 0.5 to 3.0 kg / cm ² is constantly applied upward, so that the rod 23 is always urged upward. Yes.

  In order to control the height position of the rod 23 fixed to the block chain 14 via the block unit 15 and biased upward, and the table 26 fixed thereto, a lifting guide rod 28 having a cam follower 24 at the lower end is provided on the table. 26 is fixed. The raising / lowering guide rod 28 is arrange | positioned so that the through-hole formed in the plate fixed to the cylinder 22 may be penetrated. The cam follower 24 protrudes a predetermined length in the outer peripheral direction substantially perpendicular to the rod of the lifting guide rod 28 so as to be restrained by the rod-like cam 42 and the plate-like cam 48a of the annular cam 40 disposed on the outer periphery of the rotary unit 10. It is formed as a rod-shaped body. The length of the cam follower 24 is sufficient to be reliably restrained by the annular cam 40 while being driven to rotate on the elliptical track.

  Such a workpiece supply member 20a is configured such that the cam follower 24 is constrained by the rod-like cam 42 and the plate-like cam 48a of the annular cam 40 and rotates on the elliptical track by the rotary unit 10, so Thus, a predetermined lifting motion can be given.

  The annular cam 40 is provided on the outer peripheral side of the rotary unit 10 at a predetermined position lower than the sprocket wheel 12 and the table 26. The annular cam 40 has an elliptical track that is larger than the elliptical track formed by the rotary unit 10 and substantially along the elliptical track. A portion along the transfer unit 102 that is one long side of the elliptical track is formed at a height that can maintain the table 26 at the same height as the conveyor 104. That is, the position of the table 26 whose height is controlled by the cam follower 24 of the elevating guide rod 28 matches the height of the transfer portion 103 of the transport conveyor 104. On the other hand, in the vicinity of the chuck mounting portion 202 of the cleaning device 200 that is the other long side of the elliptical track, the workpiece 100 can be pressed against the height of the chuck mounting portion 202 and held. Yes. Therefore, for example, when the height of the workpiece 100 is equal to or higher than a certain height, it may be lower than the transfer portion 103 in the vicinity of the chuck mounting portion 202, and when the workpiece is lower than that, the chuck mounting portion. The vicinity of 202 may be higher than the transfer site 103.

  Further, the elliptical orbit of the annular cam 40 is closer to the rotary unit 10 on the transfer site 103 side and is more isolated from the rotary unit 10 on the chuck mounting site 202 side. .

  Most of the elliptical track is formed by a rod-shaped cam 42, and the remaining portion is formed by a plate-shaped cam 48a. That is, the rod-shaped cam 42 forms a track other than the region near the chuck mounting portion 202 of the elliptical track, and the plate-shaped cam 48a forms a track near the chuck mounting portion 202. The plate-like cam 48a is a plate-like body having a predetermined thickness, and has an end edge capable of forming a part of the elliptical track of the annular cam 40 at the lower end thereof. The plate cam 48a is connected to the rod cam 42 in an exchangeable manner via connecting portions 49a and 49b that connect both ends of the rod cam 42 reaching the chuck mounting portion 202.

  As shown in FIG. 4, the trajectory by the plate cam 48a in the vicinity of the chuck mounting portion 202 is changed from the height A to the height H2 so that the upper end of the workpiece 100 on the table 26 reaches the height H1 of the chuck mounting portion 202. An approach section 50a that rises to a height, a mounting section 52a that maintains a height H2, and a separation section 54a that descends from a height H2 to a height B. In the approach section 50a, the workpiece 100 can reach the chuck mounting portion 202 to be chucked. In the mounting section 52a, the workpiece 100 can be securely held by the chuck, and in the separation section 54a, the table 26 can be removed from the workpiece 100. Here, the approach section 50a has a steeper slope than the separation section 54a.

  The annular cam 40 is configured to be able to swing up and down within a predetermined range with the vicinity of the transfer portion 103 facing the chuck mounting portion 202 of the rod-shaped cam 42 as a base point, whereby the plate-like cam 48a of the chuck mounting portion 202 can be moved. It can be slid up and down. The plate cam 48 is provided so as to be slidable with respect to the slide rail unit 60 and is fixed at an arbitrary height position of the slide rail unit 60 by a lock handle 62 when fixed. Sometimes, the slide rail unit 60 can be slid up and down by loosening the lock handle 62.

  The unloader unit 2b has the same configuration as the loader unit 2a, and has a difference in that the workpiece 100 is collected at the chuck attaching / detaching portion 204 and discharged to the conveying conveyor 104 at the unloading portion 105. ing. In other words, the loader unit 2a is different in that the part corresponding to the workpiece transfer part 103 and the chuck mounting part 202 corresponds to the work unloading part 105 and the chuck attaching / detaching part 204 in the unloader unit 2b. For example, as shown in FIG. 2, the unloader unit 2 b is disposed adjacent to the loader unit 2 a and between the cleaning device 200 and the transport conveyor 104, and is one straight line of the elliptical track of the rotating unit 10. The long side portion corresponds to the carry-out portion 105 of the conveyor 104, and the other long side portion of the straight line corresponds to the chuck attachment / detachment portion 204 of the cleaning device 200. For example, as shown in FIG. 4, in the loader unit 2a, the annular cam 40 slides up and down on the chuck mounting portion 202 side with the transfer portion 103 side as the center of swing, whereas the unloader unit 2b. However, the annular cam is different in that the chuck attachment / detachment portion 204 side slides up and down around the unloading portion 105 side as a swing center. Further, as shown in FIG. 4, in the plate-like cam 48a of the annular cam 40 of the unloader unit 2b, the approach section 50b is a section rising from the height B to H2, and the detachment section 52b is at the height H2. This is a section to be maintained, and the separation section 54b is a section that descends from the height H2 to the height A. In this aspect, the separation section 54b has a steeper slope than the approach section 50a, so that the workpiece 100 can be reliably attached and detached.

  Next, the operation of the loader unit 2a and the unloader unit 2b will be described. As shown in FIG. 1, the rotation unit 10 is rotated counterclockwise so that the workpiece 100 transferred from the transfer unit 102 can be sequentially received by the table 26 at the transfer portion 103. The table 26 on which the workpiece 100 is placed is rotated counterclockwise while being controlled to move up and down on an elliptical track defined by the sprocket chain 14 to a rod-shaped cam 42 via a cam follower 24. Next, when the cam follower 24 reaches the lower end edge of the plate-like cam 48a, the cam follower 24 is sequentially restrained by the approach section 50, the mounting section 52a, and the separation section 54. As a result, the workpiece 100 on the table 26 is quickly pushed into the chuck of the chuck mounting portion 202 and is maintained in a state for a while to be surely chucked, and then the table 26 is slowly lowered. Thereafter, the workpiece 100 is processed in the cleaning device 200 by the chuck.

  On the other hand, the workpiece 100 that has been cleaned reaches the chuck attaching / detaching portion 204 while being held by the chuck. The rotating unit 10 of the unloader unit 2b is rotated counterclockwise. At the chuck attaching / detaching portion 204, the table 26 is constrained by the approach section 50b, the attaching / detaching section 52b, and the separating section 54b of the plate cam 48b. The elevator is controlled. That is, the table 26 is gently raised to a height at which the workpiece 100 detached from the chuck can be placed. After the workpiece 100 is placed on the table 26, the table 26 is quickly lowered and separated from the chuck. Thereafter, the table 26 on which the workpiece 100 is placed moves on an elliptical track and is carried out to the conveyor 104 by being controlled by a slide guide or the like at the carrying-out portion 105.

  When supplying and collecting workpieces 100 of different heights, the loader unit 2a and the unloader unit 2b are slid up and down on the chuck mounting part 202 and chuck attaching / detaching part 204 sides of the plate cam 48a. The track height of the plate-like cam 48a may be adjusted so that the workpiece 100 held on the table 26 has an appropriate height with respect to the chuck mounting part 202 and the chuck attaching / detaching part 204.

  As described above, according to the loader / unloader device 2 of the present embodiment, the workpiece supply / recovery members 20 a and 20 b including the table 26 that is rotationally driven by the rotary unit 10 are controlled to be raised and lowered by the annular cam 40. Thus, the workpiece 100 can be continuously supplied to a predetermined mounting destination and recovered from a predetermined recovery source. Further, since the individual workpiece supply / recovery members 20a and 20b are continuously trajectory controlled to control the rising and lowering of the workpiece 100, the supply / recovery processing time per workpiece 100 can be easily reduced. be able to. Therefore, the loader / unloader device 2 is a loader device and an unloader device with high processing capability. Furthermore, according to such a configuration, since the processing time can be easily adjusted in accordance with the transport speed of other transport lines and the processing speed of the loaded process device, the loader / unloader device has a high adjustment capability.

  Further, according to the loader / unloader device 2, the heights of the chuck mounting part 202 and the chuck attaching / detaching part 204 can be easily adjusted, so that the workpieces 100 of different heights can be easily and quickly handled. be able to. That is, the operation corresponding to the height change of the workpiece 100 is simplified, and the time for adjusting the loader unit 2a can be shortened.

  Furthermore, according to the loader / unloader device 2, since the rotary unit 10 has an elliptical orbit around the vertical axis, the transfer part 103, the unloading part 105, the chuck mounting part 202, and the chuck detaching part 204 are provided. In both cases, a sufficient trajectory length can be taken.

  Further, according to the loader / unloader device 2, since the approach sections 50a and 50b, the loading / unloading sections 52a and 52b, and the separation sections 54a and 54b are provided, the workpiece 100 can be reliably supplied and recovered. Further, according to the loader unit 2a, the approach section 50a rises with a steeper slope than the separation section 54a, so that the workpiece 100 on the table 26 can be reliably accessed and supplied to the chuck. Moreover, the workpiece | work 100 can be reliably hold | maintained to a chuck | zipper by having the mounting area 52a. On the other hand, according to the unloader unit 2b, the separation section 54b rises with a steeper slope than the approach section 50b. Therefore, after the workpiece 100 held by the chuck is placed on the table 26, the separation section 54b is promptly removed from the chuck. The workpiece 100 can be reliably recovered on the table 26 by being separated. Moreover, the workpiece | work 100 can be reliably mounted on the table 26 by having the attachment / detachment area 52b.

  Furthermore, according to the loader / unloader device 2, the vicinity of the chuck mounting part 202 and the chuck attaching / detaching part 204 of the annular cam 40, which includes such approach sections 50a, 50b, separation sections 54a, 54b, etc., is different from the others. The elevation is controlled by a plate-like cam 48a mounted so as to be replaceable. By dividing the chuck mounting part 202 and the chuck attaching / detaching part 204 with other parts to form a track, the chuck attaching part 202 and the chuck attaching / detaching part 204 are surely chucked according to the shape and size of the workpiece 100. Ascending / descending control for supplying and recovering the workpiece 100 so as to be separated from the chuck becomes possible. Further, by making it possible to replace the portions of the annular cam 40 corresponding to the vicinity of the chuck mounting part 202 and the chuck attaching / detaching part 204, it is possible to easily deal with different types of workpieces 100. In addition, the use of the plate-like cam 48a enables highly accurate lifting control.

  Furthermore, according to the loader / unloader device 2, the annular cam 40 is close to the rotating unit 10 on the transfer part 103 side and the unloading part 105 side, and the table 26 is close to the transport conveyor 104. The workpiece 100 can be received by the table 26 and can be slid from the table 26 to the transfer conveyor 104.

  Furthermore, according to the loader / unloader apparatus 2, since the transfer unit 102 is provided, the workpiece 100 can be transferred according to the high processing capability of the loader / unloader apparatus 2. Further, the workpiece 100 can be transferred in accordance with the processing capability of the loader / unloader device 2.

  Further, according to the loader / unloader device 2, since the rotary unit 10 is provided inside the elliptical track of the annular cam 40, space can be saved.

  In the loader / unloader device 2 described above, the annular cam 40 corresponds to the cam means of the present invention, the workpiece supply member 20a and the workpiece recovery member 20b correspond to the workpiece supply / recovery means, and the cam follower 24 is restrained. The configuration is such that the rod-like cam 42 of the annular cam 40 is swingably supported on the transfer part 103 side and the carry-out part 105 side, and is vertically slid at the chuck mounting part 202 and the chuck attaching / detaching part 204. It corresponds to the means.

However, as the cam means used in the present invention, conventionally known various cam means are used. Thus, it is sufficient that the lifting control required for the workpiece supply member 20 is possible. For example, a groove cam, a rib cam, an end face cam, a cylindrical plate cam, a cylindrical rib cam, etc. can be combined as other cam means. Further, it is not necessary to combine two or more types of cam means, and it may be constituted by a single cam means. In the present embodiment, the annular cam 40 forms a substantially continuous annular track, but the present invention is not limited to this, and the track is formed only in a portion where the slide movement of the transfer member 130 is necessary. It only has to be. Therefore, the cam means does not need to have an annular track, and only needs to have an approach section and a separation section. Further, in the present embodiment, the mounting section and the detaching section are provided, but the present invention is not limited to such a form.
