## Background
BACKGROUND
1. Field of the Invention
The present invention relates to a handling apparatus for information storage disks. More particularly, the present invention relates to a handling apparatus that conveys the information disks among several working locations.
2. Description of Related Art
Information storage disks such as compact disks including Compact Disc-Recordable (CD-R), Compact Disc ReWritable (CD-RW), DVD recordable (DVD-R) etc. store digital information in a variety of formats. Compact disk drives or burners are common devices used to access the information storage disks.
There is a need to transport the information storage disks among several working locations or devices. Automatic disk handling apparatus and processing systems have been developed to increase efficiency and convenience of working. For example, when disk duplication process is performed, a blank disk is conveyed from its original location (a first location) for storage onto a tray of a duplicating apparatus (a second location) to duplicate. When the disk duplication is completed and the tray ejects the disk, the disk is removed from the tray (the second location) and conveyed to another location for storage (a third location). However, if the disk duplication fails, the disk is conveyed to another location for storage (a fourth location).
When the automatic disk handling apparatus conveys the disk among the different locations, ability to precisely position or align the disk at a given location is needed so as to accurately pick the disk up from or put the disk down on the tray or a disk holder (such as a spindle).
Therefore, there is a need to provide a handling apparatus for information storage disks to mitigate or obviate the aforementioned problems.

The disk-positioning members 213 are demountably mounted on the top 2110 of the base 211 and are arranged alongside the disk area 215 to help stack and position the disks. In the embodiment, there are four disk-positioning members 213 that are equidistantly arranged alongside the disk area 215.
Further refer to FIG. 4. The arm holder 212 is mounted on the top 2110 at the rear 2112 of the base 211 to hold and guide movements of the conveying arm 240 along a transverse direction (i.e. left and right) and a longitudinal direction (i.e. up and down). In the embodiment, the upward movement of the conveying arm 240 means that the conveying arm 240 moves away from the base 211. The arm holder 212 and the base 211 can be integrally formed or be two separate parts combined with each other. The arm holder 212 has an arm channel 2120. The arm channel 2120 has a longitudinal passage 2121 and a transverse passage 2122 that communicate with each other. In the embodiment, the arm holder 212 has a tower shape, and comprises an upper portion 2123 and a lower portion 2124. The lower portion 2124 is integrally formed on the base 211. The upper portion 2123 is demountably mounted on the lower portion 2124. The longitudinal passage 2121 extends along the axis of the arm holder 212.
The transverse passage 2122 has a top edge 2125, a bottom edge 2126 and an urging edge 2127. The top edge 2125 has a guiding step 2128. The bottom edge 2126 has an urging step 2129. The guiding step 2128 and the urging step 2129 are associated with each other. The distance between the guiding step 2128 and the urging step 2129 is substantially larger than the width of the conveying arm 240.
The conveying arm 240 is movably mounted in the arm channel 2120 and moves along the arm channel 2120. The conveying arm 240 has a head 241 extended out of the arm holder 212. The head 241 has a disk-taking device 242. In the embodiment, the disk-taking device 242 is aligned with the center of the disk area 215.
The driving device 220 is mounted in the base 211 to move the conveying arm 240 along the arm channel 2120 by means of the power transmission device 230. In the embodiment, the driving device 220 is a motor.
The power transmission device 230 is mounted in the arm holder 212 and comprises a guide rod 231, a guide seat 232 and multiple transmission members 233. In the embodiment, the guide rod 231 is a screw rod and has a guiding thread 234. The guide seat 232 is a sleeve mounted around the guide rod 231 and fastened on the conveying arm 240. The guide seat 232 has an interior thread 235. The interior thread 235 engages the guiding thread 234 on the guide rod 231 so that when the guide rod 231 is rotated, the conveying arm 240 moves along the arm channel 2120 by the threads 234, 235. The transmission members 233 are reducing gears and are mounted between the driving device 220 and the guide rod 231. The driving device 220 rotates the guide rod 231 through the transmission members 233 so as to move the conveying arm 240 along the arm channel 2120 by the threads 234, 235.
The cap 250 is mounted on the upper portion 2123 of the arm holder 212 and covers the upper portion 2123.
Refer to FIG. 1, FIG. 7 and FIG. 8. The mounting base 300 has multiple positioning protrusions 310 aligned respectively with the positioning holes 216 of one of the sides of the base 211. The mounting base 300 can be mounted on either the left 2114 or the right 2115 of the base 211 by placing the positioning protrusions 310 into the positioning holes 216. In addition, the mounting base 300 can be mounted at either the front 2111, the left 2114 or the right 2115 by placing the mounting base 300 on the connection portion 217. When a disk drive 500 is mounted on the mounting base 300, its tray is ejected at a position corresponding to the disk area 215 for the conveying arm 240 to conveniently take a disk from or place a disk on the tray. The disk drive 500 further comprises a demountable spindle 510 (in FIG. 8).
The disk holder 400 is demountably mounted at one side of the base 211 corresponding to the transverse passage 2122 of the arm channel 2120. In the embodiment, the disk holder 400 is mounted at left 2114 of the base 211 at a position under the guiding step 2128 and the urging step 2129.
Refer to FIG. 4, FIG. 5 and FIG. 6. The conveying arm 240 moves along the arm channel 2120 to convey disks among several different locations. In the embodiment, those locations include a first location where is the disk area 215 or location of the ejected tray, a second location where the conveying arm 240 abuts the urging step 2129 and a third location where the conveying arm 240 abuts the urging edge 2127. For example, when the present embodiment of the handling apparatus is applied to duplicate disks, the disk drive 500 is a disk burner.
When the duplication is completed or terminated abnormally, the tray 520 is ejected as shown in FIG. 8. The conveying arm 240 moves down until the disk-taking device 242 is inserted into the central hole of the disk on the tray 520 to take the disk from the tray 520. Rotating the guide rod 231 enables the conveying arm 240 to move upwardly along the longitudinal passage 2121 until the conveying arm 240 reaches the entrance of transverse passage 2122. The conveying arm 240 with the disk enters the transverse passage 2122 because of the rotations of the guide rod 231.
When the conveying arm 240 enters the transverse passage 2122 and abuts the urging step 2129 (as shown in FIG. 5), the conveying arm 240 will move along the urging step 2129 to accomplish a linear self-alignment because of the rotations of the guide rod 231. In the embodiment, the linear self-alignment is an upward movement as indicated by the arrow in FIG. 5 and provides good positioning effects of the conveying arm 240 at the second location for the disks. At this time, stopping the guide rod 231 and releasing the disk through the disk-taking device 242 allows the disk to fall precisely down onto the second location i.e. the central hole of the disk is precisely aligned with either the spindle of the disk holder 400 or the demountable spindle 510 to stack the disk at the second location.
If the guide rod 231 is continuously rotated after the linear self-alignment is completed along the urging step 2129, the conveying arm 240 moves along the transverse passage 2122 until the conveying arm 240 abuts the urging edge 2127 as shown in FIG. 6. Now, the conveying arm 240 is positioned at the third location. Likewise, the conveying arm 240 will move along the urging edge 2127 to accomplish a linear self-alignment because of the rotations of the guide rod 231. In the embodiment, the linear self-alignment is an upward movement as indicated by the arrow in FIG. 6 and provides good positioning effects of the conveying arm 240 at the third location for the disks. At this time, stopping the guide rod 231 and releasing the disk through the disk-taking device 242 allows the disk to fall down precisely onto the third location. Therefore, when the duplication is completed or terminated, the duplicated disks are moved and conveyed by the conveying arm 240 to the second location and are stacked by either the spindle of the disk holder 400 or the demountable spindle 510 while the failed disks are moved and conveyed by the conveying arm 240 to the third location to categorize the processed disks.
Refer to FIG. 9. A second embodiment of the handling apparatus 200 in accordance with the present invention further comprises a damping device 260. In the embodiment, the damping device 260 is mounted between the upper portion 2123 of the arm holder 212 and the cap 250 and comprises a damping member 261 and a curved rack 262. The damping member 261 is mounted in the upper portion 2123 of the arm holder 212 to provide damping characteristics and comprises a pinion 263. The curved rack 262 is mounted inside the cap 250 and engages the pinion 263. When the conveying arm 240 moves along the transverse passage 2122, the cap 250 is simultaneously rotated so that the curved rack 262 rotates the pinion 263 to allow the damping characteristic to decrease the speed of the conveying arm 240. Thus, good positioning effects are provided.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
