Claims
- 1. In processing apparatus for receiving and processing individual segments of material including a processing element for receiving individual material segments, the improvement which comprises positioning apparatus for accurate adjustment of said element, said positioning apparatus comprising:
first, second and third selectively actuatable adjusting units each including a motor equipped with an output and a coupling assembly operatively coupling each motor output with said element at corresponding fixed points on the element; fixed slide path-defining support structure separate from said element and defining a respective fixed slide path independent of said element for each of said adjusting units, at least a portion of each adjusting unit being movably mounted on a corresponding one of the fixed slide paths for translation therealong, said element being shiftable in response to actuation of said adjusting units, said element being shiftable relative to each of said fixed slide paths during adjustment of the element; and a controller coupled with said adjusting units for selective actuation of said motors in order to adjust said element.
- 2. The processing apparatus of claim 1, said fixed slide path-defining supports comprising first, second and third rail guides respectively supporting the corresponding motors of said first, second and third adjusting units for said translation thereof.
- 3. The processing apparatus of claim 1, the translatable portion of each adjusting unit being mounted on a corresponding one of said fixed slide path-defining supports for passive shifting thereof in response to actuation of the motor of at least one of the other adjusting units.
- 4. The processing apparatus of claim 1, each of said fixed slide paths being essentially rectilinear.
- 5. The processing apparatus of claim 1, two of said fixed slide paths being substantially parallel with each other and the other of said fixed slide paths being transverse to said two fixed slide paths.
- 6. The processing apparatus of claim 1, the translatable portion of each of said adjusting units including the corresponding motor of the adjusting unit.
- 7. The processing apparatus of claim 1, including first, second and third rail guides respectively supporting the corresponding motors of said first, second and third adjusting units for said translation thereof.
- 8. The processing apparatus of claim 1, two of said fixed slide paths being substantially parallel with each other and the other of said fixed slide paths being transverse to said two fixed slide paths.
- 9. The processing apparatus of claim 1, wherein each adjusting unit motor output includes a rotatable shaft, and wherein the coupling assembly associated with a respective adjusting unit is an eccentric coupler between the table and a corresponding motor output shaft.
- 10. The processing apparatus of claim 9, wherein each of said eccentric couplers includes a pin having an axis and rotatably received within the element at a corresponding fixed point, and an eccentric block, a portion of the eccentric block being connected to the pin and another portion of the block being connected to the corresponding motor output shaft in disposition such that the axis of the pin is in offset eccentric relationship to the axis of rotation of the shaft.
