Raytheon® Base Leg Bolt Machine

The function of this machine is to assemble four leg bolts into an appliance base and load into a carton.

Sequence of Operation:

The operator will prime the two (2) collators with bases and folded cartons. The operator will initiate cycle start. The horizontal axis will index to the base collator. When the transfer unit reaches the base collator, the vertical axis will lower, placing the vacuum cups onto the base at the top of the collator. The vacuum will turn on and the vertical axis will raise upon sensing the vacuum pull. Once at the top of the travel, the transfer unit will then index to the assembly fixture. While in transit, the base collator will deliver another base to the pick up position. When the transfer unit reaches the assembly fixture, the vertical axis will place the base onto the fixture and turn off the vacuum then lift the top of its travel. At this time, the four (4) leg bolts will be fed and driven into the base.

While the leg bolts are being driven, the horizontal axis will index to the folded carton collator and stop. The vertical axis will descend and contact the folded carton at the top of the collator. The transfer system will draw a vacuum on the folded carton and lift it from the collator. Once at the top of the vertical stroke, the transfer system will index to the roller conveyor. As the transfer system is moving to the roller conveyor, the collator will move another folded carton up to the pickup point. When the transfer system reaches the roller conveyor, the vertical axis will lower and deposit the folded carton onto the roller conveyor. The folded carton will be released and the vertical axis will raise to the top of the stroke where it will then index to the assembly fixture.

When the transfer system reaches the assembly fixture, it will lower and draw a vacuum on the base that has just had the four (4) leg bolts assembled to it. The transfer unit will lift the base and deliver it to the awaiting folded carton located on the roller conveyor. After depositing the base on the folded carton, the transfer unit will then repeat the entire sequence after the folded carton and base are released to the assembly.
