Title: Improvements relating to apparatus for compressing a coating of comminuted material around a preformed core
IPC: B30B11/34
Filed: 1956-05-18
Abstract: 820,636. Rotary-table compression moulding machines. EVANS MEDICAL SUPPLIERS Ltd. May 18, 1956 [May 21, 1955, June 28, 1955], No. 15649/56. Addition to 796,810. Class 87(2). The tablet-forming apparatus of the parent Specification is modified by the provision of a plurality of pairs of punches movable in dies in a rotatable die place and separate strippers for ejecting perfect and imperfect tablets, the strippers being arranged one after the other in the direction of rotation of the die plate, one being movable into and out of an ejecting position, the order being fixed. The movement of the movable stripper may be controlled by a resiliently supported roller 19, Fig. 4, carried on pivoted levers 20 rigidly connected to an arm 21 carrying an electrical contact 23 engageable with a fixed contact 24. If the tablet being compressed contains a core the roller 19 is depressed sufficiently to engage the contacts 23, 24, which are those of a micro-switch 30, Fig. 5. One of a series of condensers 31 carried by a disc 32 rotating in synchronism with the die table 15 is then charged as a contact 33 connected thereto engages a contact 34 connected to a current supply through the closed switch 30. Whilst the cored tablet travels to a discharge position B the said contact 33 moves to engage a contact 35 so that the condenser 31 is discharged through a relay coil 36 to close contacts 37, 38. The circuit closed by the contacts 37 energizes a solenoid 42 to lift a stripper plate 25 to allow the cored tablet to pass to and be discharged by a further stripper plate 26. When, however, a coreless tablet is compressed the switch 30 is not closed and the solenoid 42 remains de-energized so that the coreless tablet is discharged by the stripper plate 25. The closing of the contacts 38 ensures that the relay coil 36 remains energized for a period during which a circuit breaker 39 is held closed by the engagement of a punch 18 with an actuating arm 41, such period being sufficient to allow the cored tablet to pass the plate 25 but not sufficient to allow passage of the following tablet. In a further construction, Fig. 6 (not shown) the micro-switch is closed when an imperfect. tablet is compressed and opened on the compression of a perfect tablet.
