Abstract

A bale accumulator and optional caboose are controlled by a microprocessor-based control circuit associated with and controlling the baler which pulls the bale accumulator. The control circuit monitors bale switches actuated by the presence of bales on four tables, two switches indicating the position of a bale push bar, and three table switches indicating when individual ones of three of the tables are latched or released for dumping bales therefrom. An operator's panel provides a visual display of the status of the bale accumulator and includes switches which may be actuated by the operator. In response to the switches on the bale accumulator the control circuit controls the push bar to move bales from a center table onto a left or right table at the sides of the center table, or inhibits movement of the push bar so that a succeeding bale ejected from the baler pushes a bale on the center table onto a trailing fourth table. In response to actuation of a dump switch the control circuit determines which tables should be unlatched to dump a bale therefrom, and energizes a motor or motors to unlatch the tables as determined by the control circuit. All operations of the bale accumulator are automatic except for operator actuation of the dump switches.

Independent Claims | See all claims (13)

  1. 1. In a bale accumulator having at least a center table for receiving bales of crop material pushed from the rear of a baler, right and left tables, and push bar mans including a push bar for pushing a bale on the center table to the right or left table, the improvement comprising:bale switch means associated with each of said tables for sensing a bale thereon;push bar switch means for sensing when said push bar is at a first position on the right side of said center table or a second position on the left side of said center table;control circuit means responsive to said push bar switch means and said bale switch means for selectively actuating said push bar means to selectively control movement of said push bar between said first and second positions;dump means associated with said right table and said left table; anda plurality of manually actuated electrical switches for selecting the number of bales to be dumped and initiating a dumping sequence;said control circuit means being responsive to said manually actuated switches, said bale switch means and said push bar switch means for determining which tables should be dumped and controlling said dumping sequence so that all tables not dumped may have a bale pushed thereon prior to an initiation of a further dumping sequence, said control circuit means applying signals to actuate the dump means associated with the tables which should be dumped.
  2. 11. 1. In a bale accumulator having at least a center table for receiving bales of crop material pushed from the rear of a baler, right and left tables, and push bar mans including a push bar for pushing a bale on the center table to the right or left table, the improvement comprising:bale switch means associated with each of said tables for sensing a bale thereon;push bar switch means for sensing when said push bar is at a first position on the right side of said center table or a second position on the left side of said center table; andcontrol circuit means responsive to said push bar switch means and said bale switch means for selectively actuating said push bar means to selectively control movement of said push bar between said first and second positions; said right and left tables being provided with associated extensions, hinge means connecting each extension to its associated table so that an extension may be folded to rest on top of its table, the bale switch means for the right and left tables being positioned such that a bale switch associated with a given table is actuated if the extension for the table is folded.
  3. 12. In a bale accumulator having at least a center table for receiving bales of crop material pushed from the rear of a baler, right and left tables, and push bar mans including a push bar for pushing a bale on the center table to the right or left table, the improvement comprising:bale switch means associated with each of said tables for sensing a bale thereon;push bar switch means for sensing when said push bar is at a first position on the right side of said center table or a second position on the left side of said center table;control circuit means responsive to said push bar switch means and said bale switch means for selectively actuating said push bar means to selectively control movement of said push bar between said first and second positions;dump means associated with each table except the center table; anda plurality of manually actuated electrical switches for selecting the number of bales to be dumped and initiating a dumping sequence;said control circuit means being responsive to said manually switches, said bale switch means and said push bar switch means for determining which tables should be dumped and the sequence in which they should be dumped, said control circuit means applying signals to actuate the dump means associated with the tables which should be dumped in the sequence in which they should be dumped.
