Abstract

A stand-alone parts accumulator that can be retrofit as a unitary add-on to an existing production line. The parts accumulator includes: (a) a generally linear conveyor; (b) a rotary table comprising a spiral barrier guide defining a path from an outer region of the table to an inner region of the table; (c) a connector attaching the linear conveyor to the rotary table; (d) a motor connected to rotate the rotary table; (e) an adjustable controller connected to the motor to control rotation of the table. A single bracket can be used to support the conveyor in either a left-hand or a right-hand configuration. The conveyor motor is positioned substantially within the footprint of the conveyor. The conveyor is narrow (between about 2 inches and about 8 inches).

Claims

1. A stand-alone unitary parts accumulator/conveyor assembly comprising

(a) a generally linear conveyor delivering parts to a rotary accumulator table;

(b) the rotary accumulator table comprising a spiral barrier guide defining a path from an outer region of the table to an inner region of the table, the path being accessible for removal of parts accumulated on the table;

(c) a connector attaching the linear conveyor to the rotary table;

(d) a motor connected to rotate the rotary table;

(e) an adjustable controller connected to the motor to control rotation of the table;

said controller including a adjustable control to match rotary table rotation with part-cycle delivery; and

(f) a reversible bracket mounting the conveyor to the parts accumulator in position where the conveyor is offset from a table radius, the bracket comprising;

(1) a plate for mounting the bracket to the parts accumulator;

(2) an support attached to the plate at a slant, the support including a first surface and a second surface generally opposite and spaced from the first surface; and

(3) a conveyor cradle attached to either the first support surface or the second support surface,

wherein the first surface includes a first feature sized and shaped to cooperate with a fastener to position the cradle in a first position, parallel to, and facing away from, the first surface, and the second surface includes a second feature sized and shaped to cooperate with a fastener to position the cradle in a second position, parallel to, and facing away from, the second surface, whereby the cradle may be fastened either to the first surface in the first position or to the second surface in the second position.

2. The parts accumulator/conveyor assembly of claim 1 in which the controller is independently powered.

3. The parts accumulator/conveyor assembly of claim 1 further comprising a second motor connected to more the generally linear conveyor.

4. The parts accumulator/conveyor assembly of claim 1 comprising a bracket supporting the generally linear conveyor.

5. The parts accumulator/conveyor assembly of claim 1 in which the conveyor is between 2″

and 8″

wide.

6. The parts accumulator conveyor assembly of claim 1 in which the parts accumulator comprises a rotary table comprising a spiral barrier guide defining a path from an outer region of the table to an inner region of the table;

and the accumulator comprises,

(a) a motor connected to rotate the rotary table;

(b) an adjustable controller connected to the motor to control rotation of the table.

7. The parts accumulator conveyor assembly of claim 1 in which the conveyor has a width of between 2 inches and 8 inches.

8. The parts/accumulator conveyor assembly of claim 1 further comprising a motor mounted to drive the conveyor, the motor being positioned substantially within the footprint of the conveyor.
