1 Specification for TBJ Model 3600 & 4800 Automatic Bedding Dispensers Description: The Model 3600 & 4800 Bedding Dispensers are automatic, conveyorized systems designed to dispense controlled amounts of bedding into rodent cages as they are autmaticaly conveyed through the dispensing section. The unit is designed to accept animal cages as they are discharged from a conveyorized tunnel washer or as a stand alone unit and shall be capable of handling most solid beddings currently available Size Configuration: Tunnel opening: 10" high Overall: 64 1/2" high x 96" long x 83" wide Conveyor Belt Height: 30" Conveyor Belt Width: 36" 4800 Size Configuration: Operation: Tunnel opening: 10" high Overall: 64 1/2" high x 96" long x 95" wide Conveyor Belt Height: 30" Conveyor Belt Width: 48" Filling the hopper with bedding The storage-dispensing hopper is filled by dumping bedding into the hopper located alongside the cage conveyor bed. A hinged door is provided to seal the hopper when the dispenser in not being charged with bedding. The hopper includes a removable safety grate with an interlock sensor. It the safety grate is removed during operation, the unit will temporarily shut down until the grate is replaced. Dispensing bedding When dispensing bedding into cages, both powered roller and dispensing motor shall be turned on. A sheet of bedding is continuously dispensed from

2 above the cage conveyor rollers. This sheet extends across the full width of the cage conveyor. As cages pass top-side-up through this sheet of bedding, a controlled level of bedding material is deposited into the cages. The cages can pass beneath the hopper in any random pattern and will be filled with the same amount of bedding per square inch of cage bottom. The rate at which the bedding is being dispensed is adjustable via a dispenser drive control located on the control panel, so the amount of bedding deposited in the cages can be varied. The bedding which falls outside of the cages will fall through the open conveyor rollers and into the bottom loading hopper. It is then returned to the side storage hopper by the dispensing conveyor. Cages may be manually loaded onto the dispenser conveyor top-side-up, or cages may be automatically inverted and transferred to the dispenser conveyor as they come out of a tunnel washer.
