Title: Improvements relating to apparatus for effecting controlled relative displacement between relatively movable parts
Inventor: LANE CLAYTON ARBUTHNOT
IPC: B23Q16/02
Filed: 1955-10-10
Abstract: 799,638. Packaging-machines. SIEMENS EDISON SWAN, Ltd. Sept. 20, 1956 [Oct. 10, 1955], No. 28807/55. Class 94(1). [Also in Groups XXII and XXIX] In a machine for packaging articles in trays sub-divided into a number of compartments arranged in rows, the positioning of the trays is effected by apparatus which comprises a singleplunger pump 4 discharging through a line 7 and a reversing valve 9 to a secondary motor for effecting displacement from row to row (secondary indexing) and constituted by a stationary cylinder 16 containing pistons 18, 19 on a rod 17, and to a primary motor for effecting movement from position to position along the rows (primary indexing) and constituted by a stationary piston 27 in a moving cylinder 26. As shown the pump discharges through line 7, reversing valve 9, a line 14, the left hand side of cylinder 16, and a line 24 to the primary motor, each stroke of the pump moving the primary motor cylinder 26 through a fraction of its total stroke equal to the length of primary index required. At its left hand limit position cylinder 26 closes a switch 31 which energizes a solenoid to reverse valve 9. The next discharge stroke of the pump then supplies liquid through line 7 and a line 15 to the right hand end of the cylinder 16, moving the pistons 18, 19 one complete stroke to the left to effect a secondary index. Subsequent strokes of the pump move the primary cylinder 26 step-by-step to the right till a limit switch 32 is closed. A master switch 33 is opened by pressure in the pump discharge to ensure that after the limit switch 31 or 32 has closed, the solenoids are energized only on the pump suction stroke. The secondary index movements are effected from the piston rod 17 through a ratchet wheel 35 actuated by ratchet bars 36, 37 spring-urged into engagement with the wheel. If a third direction of indexing is required, as for example when a number of compartmented trays stacked one above the other are being filled, and when the top tray is filled it is removed and the remaining trays are raised by an index in the third direction, then there is provided another cylinder and double piston device and a further reversing valve with means for reversing this valve when the primary and secondary indexing devices reach a limit position.
