Abstract: 1386297 Automatic control of tool selection EX-CELL-O CORP 23 June 1972 [23 June 1971]  29575/72 Heading G3N In a program controlled tool changer in which tools are placed in pots on an endless conveyer 12 and are identified by binary coded decimal digits stored in respective memory modules 34, the modules, under control of rotary switch 18 are sequentially addressed in synchronism with conveyer movement, the digits in the addressed module being compared with digits respresenting the next desired tool supplied by master control 14 programmed, via a tape, to give a defined sequence of desired tools. The comparison takes place in coincidence unit 16 which causes the conveyer to be driven until coincidence prevails, whence tool exchange takes place, the next desired tool being at the exchange location. Subsequent to the exchange a sequence of pulses provided by control register 24, see also Fig.3 (not shown), cause (i) the binary coded decimal digits in spindle storage 38, representing the code of the last used tool to be transferred to that module 34 being addressed at coincidence, (ii) the digits from the master control representing the tool about to be used to be transferred to the spindle storage 38, and (iii) a signal to be passed to the master control 14 indicating that the next desired tool code can be passed to the coincidence unit 16. Setting Up. As a tool is placed on the conveyer at the exchange location, a set of thumbwheels (52), Fig.3 (not shown) in the entry logic unit 24 are used to feed to the momentarily addressed module 34 the corresponding tool code, transfer being enabled by pressing button (64), associated with a holding circuit assuring that enabling continues until button (64) returns completely to its unactuated state. During subsequent use, upon tool exchange, the code in the memory being addressed is changed via leads (70), from the spindle storage unit 38. Pushbutton (82) (Fig.3) allows the code in the addressed module 34 to be cleared, together with the spindle storage register 38, and the control register 24.  Memory modules 34, and spindle storage 38 each comprise, for each decimal digit of the tool codes, four J-K flip-flops and input gates (98, 100, 102, 104) Fig.4 (not shown); (114, 116, 118, 120) Fig.5 (not shown). Coincidence logic unit 16, Fig.6 (not shown). The code of the next desired tool is fed via leads (21) to exclusive OR gates (138) also receiving the code of the momentarily addressed module 34 on leads (42) and, via NANDS (140, 142, 144) enable the energization of driver (150) moving conveyer 12, until the two codes are coincident.  Switch interface 30, Fig.2 (not shown). Voltage level converters (48) reduce operating signals to the modules, switch (44) whose coverted output provides an input NAND gates (50) being closed only when a pot on the conveyer is in the tool exchange location.
