Messetromkreis is required, brought in through a line 10 and duroh an adjustable pressure regulator 11 as well an adjustable constriction 12 installed therein is controlled. A typical counter pressure circuit is shown, in which air flows from the regulator 11 through the line 10 to a measuring head or spindle 13. The measurement signal is duroh a line 14 on a control nozzle 15 and on Transferring amplification devices, which are shown as a proportional amplifier 16 with a housing 16. An adjustable Hegler 17 promotes the Primary air flow for the booster circuit through a line 20 to a supply duct 21 in the housing 16a, around a fluid delivery jet up there to let flow. The controller 17 also supplies the control nozzle 23 of the amplifier 16 and is opposite the Control nozzle 15 arranged.

regulated air through a line 31 to a number one Decision-making elements or pneumatic flip-flop devices 30 and 32. Since the units 32 and 33 Identical, only the unit 32 is shown in a perspective representation in the section in FIG. 5 shown. Each flip-flop device 32 and 33 has a corresponding one Housing 32a and 33a and corresponding supply channels

34 and 35 for blowing a fluid supply jet therethrough. The feed nozzle 34 and

35 are each supplied by supply lines 36 and 37 7, which are connected to the supply line 31 stand. Lines 40 and 41 (including corresponding constrictions 44 and 45) are at one end with the line .51 in connection and supply the corresponding control nozzles 4 2 and 43 of the flip-flop devices 32 and 33 The pressure point at which each hip-flop device is excited, is stopped by such settlements, did 6 * κ inner diameter of the ring 26 to match. Dit Flip-flops 32 and 33 operate in conjunction with valve devices, e.g. B. the control valve 38 with a spring-loaded valve device 39 cooperates to classify the part in this example in one of three categories to classify. According to the position in FIGS. 1 and 5, each flip-flop device 32 and 33 has a central one Discharge channel 32o and J3d, which are generally opposite your corresponding supply channel are arranged, that is Excessive means of flow that is not through one or the other other delivery channel located in it flows, abtufUhren, so that the flow either, through the one or the other delivery channel ^ dppt, depending on the

Energy of the assigned control nozzle.

The flip-flop fluid flow rates 32 and 33 and the valve devices 38 and 39 are fed to a number of read-in elements 46, 47 and 48. The measurement information for a part of a given class is depending on the size of the part in one of these Read in elements, which is described in more detail below. The air supply for the reading elements 46, 47 and 48 is provided by energizing the inlet valve 52, which is in a line 53 downstream of the pressure regulator 54 is installed. The inlet valve 52 is only one of a number of valve units which are automatically inserted into one cycle can be operated to perform the functions of the device, which will be described later.

After the ping 26 has been led into the measuring station, this ring is glued on and measured - as already mentioned - and a signal is generated by the amplifier 16, the flip-flop devices 32 and 33 working together with valve devices 38 and 39 to read-in unit 46 or 48, depending on whether the part is a Is oversized, acceptable, or undersized. While the part is still in the measuring station, will energizes valve 52 so as to clear the signal from the part and dynamically apply that signal in element 46 or 48 hold, depending on the size classification.

After a given measurement signal has thus been classified in a given class, namely by exciting a given one

009883/0307 - 10 -

Reading element, the signal is now stored in the device for later use according to a predetermined working cycle. Such storage is carried out using the storage devices which include a first storage row with storage units 55, 56 and 57, which correspond to units 46, 47 and 48, respectively are, for the sake of simplicity of illustration, a full description of m given only with reference to the typical Speiohereinheit 56 in Pig. 6 is shown in more detail. Its sole description applies completely to all such reading units, storage units and switching units. The unit comprises a housing 56a and a supply channel 56b in the housing for flowing a fluid supply jet therefrom. The delivery channel devices in the housing 56a include a delivery channel 56c, which normally delivers fluid to the environment except when receiving a measurement signal from the unit immediately preceding it, and a delivery channel 56d. The control nozzle device in the housing 56a comprises a control nozzle 56e which, when receiving a flow from the unit immediately preceding it, deflects the feed jet 56b from the channel emitting to the environment to the opposite channel, 56d in this illustration. It can thus be seen that a measurement signal transfer is carried out by deflecting the feed beam by the control nozzle, as soon as it receives a heat signal from the unit immediately preceding it. '^ "^ c I

009883/0307 - 11 -

The fluid supply for the storage units 55 _t 56 and 57 is through opening valve means, for example , that β it flows out in a line 71. ig provided by esc * pressure regulator 72 installed air valve * If the signal is thus withheld in the first row of the storage units, then valve 52 is opened, which effectively closes units 46, 47 and 48 in preparation for another one from the next measuring part 2t. receiving signal. From this point the 3D sequence of operations is the way in which

If the stored signal is improved, depending on whether the part has a transition: S5 & e has _{f is} acceptable, or is undersized, if the part is oversized, then the pressure in the conduit 14 is reduced, and therefore the energy is of the SteuorstrahleE 15 is reduced accordingly. This enables the control beam 23 to deflect the feed beam 21 deü amplifier 16, se that it empties through its delivery channel 28 and in turn a plus to the control havens 60 and 61 of the flip-flop devices 32 and 33 is provided. The control diaphragms 60 and 61 direct the plus

Ψ from the supply nozzles 34 and 35 from and to the discharge channels 62 and 63 of the units 32 and 33 respectively.

The flow through channel 63 enters control valve 38. However, since there is no flow through a channel 64 to the flip-plop device 32, the signal is lost at this point. The flow through the channel 62 is transmitted to the unit 46, and the signal is read in by energizing the valve 92 and for subsequent transmission to the memory unit 55 for use . held at a later point in the cycle.

009883/0307 - 12 -

If the portion is acceptable, then the pressure in line 14 provides sufficient energy for control duct 15 so that less flow through channel 28 of amplifier 16 is diverted. The flow is such that the control nozzle 60 of the plip-flop device 32 does not deflect the feed jet 34 and thus allows the control jet 42 to deflect the flow to the channel 64 and from there to the valve 39. However, the flow of the channel 28 is sufficient to control the beam 61 to cause the flip-flop means 33 to divert the flow of the SteuerdUee 35 to the output channel 63 A. Thus, with the provision of a feed to the valve 39 and to the control valve yB is the measurement signal to the üpeichereinhei-t 47 transferred, and the signal is duroh excitation dee valves 92 read · The signal is then transferred to the memory unit 56 for later in the Cycle to be used.

If the part has a sub-size, then the pressure in the line 14 is compared below the two previous classes of large, and thus there is a relatively small \ passage of the discharge duct 28 dee amplifier 16, and the SteuerdUeen 42 and 43 of the units 32 or 33 divert the flow through these units to the delivery channels 64 and 65 of the same. If there is no signal to control valve 38 , the signal to channel 64 is canceled and flow through channel 65 provides a signal which is read into unit 48 and then to memory units 57 for later use in the cycle Will be transmitted *

The description of the embodiment s "example of the invention has shown 4ββ as a measurement signal for a V / c piece 25 transferred oversized, decently sized, or undersized and is initially stored in units 55, 56 or 57.

As already explained above, in this exemplary embodiment parts are continuously used by the system in FIG Sub-steps transferred to the heating station and from this station one after the other through rooting stations for oversize,

fc acceptable size and undersize led where they are depending on their Size classification are ejected. This work cycle is used for each partial movement between the individual stations repeated. For each classification are storage units provided, welohe in their number of the number of work cycles or partial movements between the measuring station and the correspond to the corresponding dialing station. In order to provide the correct delay or signal storage, the signal is for each classification in a sequence between the storage units for the corresponding class to one

™ Ending Storage Unit Transferring where it is of use is fed to actuate the associated dialing device at the corresponding station. The way in which a Part of a given klaase is ejected at the correct station, as shown in Figures 1 and 2 of the drawings, however, in order to provide a complete description of this invention, an acceptable part is read through the complete Work cycle tracked.

If an acceptable part is clamped in the measuring station, then a signal is provided and into the unit 47

let in immediately before the start of the guiding process. The part is then taken to the next station, while the signal remains in unit 47, prior to clamping the next part in position in FIG Preparation of the measurement process and therefore another signal. From Fig. 3 it can be seen that the signal from the unit 47 is transferred to the unit 56 in the first memory row during the guide movement. This will be exciting reached a valve 70 in a line 71, namely downstream of the adjustable pressure regulator 72, weloher the Flow through this line regulates. It should be noted that j as well as the part reaches the first station and the signal held in the unit 56 is read, the valve 52 is closed in order to cancel the measurement signal in the read-in units, namely the unit 47 in this case and prepare these units for a signal from the closest part to be positioned and measured.

The next process is to read any signals present in the storage units. This is duroh A valve 80 which is arranged in a line 81 on the downstream side of the regulator 82 opens.

Of course, if the part was oversized, a signal would be available from unit 55 and it would be at körjmjrÜÄhar arrangement of the part at the first station Signal for the usage control means has been provided be e.g. B. a control valve 83 and a valve 84, welohe the flow to the means of use included one

Control actuator 85 to control the portion of the

009883/0307

Eject guide conveyor 86 into a chute 87. The conveyor 86 is guided in time coordination with the work cycle.

When storing the measuring signal in the first memory row, in particular in the unit 56, in this order for an acceptable part are fluid signal transmission devices, the ones with the plasticizers and the Work out storage means, provided in order to ^ to transmit stored signals according to the predetermined work cycle. To such signal transmission devices include switching initiation and means for introducing Fluid to these, as well as valve devices for them, in order to thus provide a given signal with the desired

until
delay in transferring öee to use it. The signal

for the acceptable portion of which is held in the memory unit 56, is moved from the first memory row, while the part is still in the Übergrößewählatation, is opened in the abströmeeitig disposed in the conduit 74 from the w adjustable pressure regulator 75 valve 73rd

The signal is thus sent to the unit 76 in a first Transfer series of switches containing units 76 and 77, and then flow to the storage units blocked by the solenoid valve 70 in order to effectively reset the storage units in preparation for a further signal. The read-in valve 52 is then opened in preparation for a further signal to be provided 1tt ^ as well another part is brought into the measuring position while

at the same time the air flow to the storage units is blocked in order to transfer the measurement signal from the new to the heating station introduced part effectively in the signal in the first isolate switching series.

The measurement signal from the acceptable unit is then transmitted to a unit 90 in a second series of circuits which includes units 90 and 91. The air flow for the second switch arm is provided by opening the valve 92, which is installed in a line 93 on the downstream side of the Q adjustable pressure control device 94. Air flow to the first and second rows of switches is continued simultaneously for a short period of time, whereupon the acceptable part is advanced to the next position while generally simultaneously moving another part into the measuring station. During the transfer process, the flow is blocked to the first circuit row, ι during the flux and thus the signal in the second switching order, in this "case, the unit 90 retained. A flow is provided to the storage units at the same time as the flow to the first row of switches is stopped. The measurement signal for the acceptable part is thus effectively isolated in the storage unit 90 in the second row of switches and transferred to the unit 95 in the second row of memories, while the measurement signal from a new part is obtained and held in the first memory row.

The measurement signal of the acceptable part is obtained by opening the Valve 80, which is the drive power source, in this example air, for the Senutzungeneinrichtungen or

While the valve 70 is still in its energized state ", becomes the signal from the usage control device unit 95 provided, which include a control valve 100 that cooperates with a valve 101 and thereby energizing the actuator 102 and the acceptable portion now in the dial station for acceptable Parts lies, ejects into a chute 103.

If the part had been undersized, then his would have been Signal has been transmitted to the memory unit 57 and the undersize signal by aich repeating switching clocks has been transferred to the storage unit 96 with steps similar to transferring a Signal to the unit 95 for an acceptable part · When reading the signal when the part in the Dial station for a reasonable size, there would be no signal for the control valve 100 is available and thus the undersized wedge would not be ejected at that point. From the representation of the work cycle in Pig. 3 shows that the next step would be to stop the flow to the reading valve 80, which a Energizing the valve 73 connects to a
