Automatic Storage And Retrieval Machine
Before an automatic storage and retrieval system is implemented at a new site
, the storage and retrieval machine is typically tested on a test apparatus at the manufacturing facility. Testing is followed by removal of the storage and retrieval machine from the test apparatus. In prior art systems, this involves completely disconnecting the storage and retrieval machine from all control and power equipment, and disassembling the machine for shipment to the new site. After shipping, the storage and retrieval machine is reassembled on a track and storage rack at the new site, rewired and reconnected to an on-site power source, and reintegrated with controls at the new site, the controls being shipped separate from the machine. Thereafter, the storage and retrieval machine and on-site control unit are subjected to vehicle/system testing, adjustment, and general debugging operations. This initial set-up is time consuming and may delay operation of the system for as much as a week or more.
More particularly, the shipping module, includes a frame that serves as a shipping container for the automatic storage and retrieval system machine, its electrical controls, and a portion of its drive mechanism. The frame is easily disconnected from a test apparatus, and includes an upper rail segment that extends the upper rail on the test apparatus so that the storage and retrieval machine can be pulled within the frame. To ready the machine for shipment, retainer assemblies (used to maintain the machine on the track) at the front and rear of the machine are replaced with brackets that are fastened to the frame, and the roller assembly on top of the mast is replaced with a bracket that is fastened to the upper rail segment. The carriage is also fixed against movement along the mast via a block and strap arrangement.
Once at the new site, the shipping module is unloaded, rolled into position next to the storage rack, and attached as an integral part of the storage rack. Thereafter, the retainer and roller assemblies are replaced on the automatic storage and retrieval system machine to support the machine for horizontal movement along the track and the upper rail, the umbilical cord sections are unrolled and reconnected, the control unit is connected to the site power source, and a suitable drive belt is mounted on the drive mechanism and connected to the storage and retrieval machine. Once installed the shipping module provides a permanent maintenance bay or area for the storage and retrieval machine.
