Auto loading device for data storage cartridges
View Patent ↗A vertical autoloader design enables multiple data cartridges to be selectively loaded into a drive while minimizing the device footprint. The structure of the vertical autoloader incorporates Geneva steps into the walls of the autoloader. The Geneva steps interface with gearing on a drive carriage to move the drive vertically. The data cartridges are inserted into slots on the front of the vertical autoloader, and the data cartridges not currently loaded into the drive can be removed and replaced while the autoloader is in operation. Further, the vertical autoloader includes prevent devices in the cartridge slots to ensure the data cartridges are loaded correctly.
1. An autoloader for a data cartridge including an underside with a slot, comprising:
a housing having a plurality of data cartridge slots;
a drive that is movable between the data cartridge slots; and
a prevent device located within each of the plurality of data cartridge slots,
wherein the prevent device prohibits insertion of a data cartridge into the data cartridge slot if the data cartridge is not properly oriented, the prevent device includes a positive insertion stop slidably receivable within the underside slot, the prevent device interacts with the drive to allow the cartridge to move beyond the positive insertion stop by slidably receiving the positive insertion stop in the underside slot for loading the cartridge into the drive when the drive is positioned at one of the plurality of data cartridge slots, the positive insertion stop includes a pair of tabs, and the underside slot includes a pair of underside slots configured to slidably receive the pair of tabs.
2. The autoloader of claim 1 , wherein the cartridge is loaded into the drive using a simple rotary motion.
3. The autoloader of claim 1 , wherein the data cartridge is shaped in a manner to interact with the prevent device when properly inserted into one of the plurality of data cartridge slots.
4. The autoloader of claim 1 , wherein the underside slot extends along the underside of the cartridge less than the entire length of the cartridge.
5. The autoloader of claim 4 , wherein the underside slot extends along the underside of the cartridge roughly one third the length of the cartridge.
6. The autoloader of claim 1 , wherein the prevent device is spring-loaded.
7. The autoloader of claim 1 , wherein the cartridge includes a leading edge and the prevent device includes a cam configured to engage the leading edge of the cartridge to cause the prevent device to be moved to an out-of-the-way position.
8. The autoloader of claim 7 , wherein the cam is angled and the leading edge of the cartridge engages the angled cam, forcing the prevent device to rotate downward, lowering the positive insertion stop to the out-of-the-way position.
9. An autoloader for a data cartridge including an underside with a slot, comprising:
a housing having a plurality of data cartridge slots;
a drive that is movable between the data cartridge slots; and
a prevent device located within each of the plurality of data cartridge slots,
wherein the prevent device prohibits insertion of a data cartridge into the data cartridge slot if the data cartridge is not properly oriented, the prevent device includes a positive insertion stop slidably receivable within the underside slot, and the prevent device interacts with the drive to allow the cartridge to move beyond the positive insertion stop by slidably receiving the positive insertion stop in the underside slot for loading the cartridge into the drive when the drive is positioned at one of the plurality of data cartridge slots,
wherein the cartridge includes a leading edge, the prevent device includes an angled cam, and underside slot extends along the underside of the cartridge less than the entire length of the cartridge and includes a underside slot end, and the positive insertion stop and cam are spaced relative to each other so that the leading edge of the cartridge engages the angled cam, forcing the prevent device to rotate downward, lowering the positive insertion stop to an out-of-way position, before the positive insertion stop engages the underside slot end.
10. An autoloader, comprising:
a housing having a plurality of data cartridge slots;
a drive that is movable between the data cartridge slots; and
a prevent device located within each of the plurality of data cartridge slots and prohibiting insertion of a data cartridge into the data cartridge slot if the data cartridge is not properly oriented, the prevent device including a positive insertion stop and a cam offset rearward relative to the positive insertion stop so that upon insertion of the data cartridge into the data cartridge slot a leading edge of the data cartridge engages the cam, forcing the positive insertion stop to an out-of-the-way position, before the positive insertion stop stops insertion of the data cartridge into the data cartridge slot.
11. The autoloader of claim 10 , wherein the data cartridge is configured to receive the positive insertion stop at least partially therein with insertion of the data cartridge into the data cartridge slot.
12. The autoloader of claim 10 , wherein the positive insertion stop includes a pair of tabs and the cartridge includes an underside with a pair of underside slots configured to slidably receive the pair of tabs at least partially therein.
13. The autoloader of claim 10 , wherein the cartridge includes an underside with a slot extending less than the entire length of the cartridge.
14. The autoloader of claim 13 , wherein cartridge includes a length and the underside slot extends along the underside of the cartridge roughly one third the length of the cartridge.
15. The autoloader of claim 10 , wherein the prevent device is spring-loaded.
16. The autoloader of claim 10 , wherein the cam is angled and the leading edge of the cartridge engages the angled cam, forcing the prevent device to rotate downward, lowering the positive insertion stop to the out-of-the-way position.
17. The autoloader of claim 16 , wherein the cartridge includes a length and an underside with a slot extending along the underside of the cartridge less than the entire length of the cartridge, the underside slot including a slot end, and the positive insertion stop and cam are spaced relative to each other so that the leading edge of the cartridge engages the angled cam, forcing the prevent device to rotate downward, lowering the positive insertion stop to the out-of-the-way position, before the positive insertion stop engages the underside slot end.
