Output signals · But there are also codes Generate output signals that represent a mathematical function of signal input shaft rotation, for example the sine of the angle of rotation. However, none of the known sealing eggs was previously able to provide the required position signals for an electronically controlled circular knitting machine

The knitting machine control system in which the locking egg described herein is intended to operate is described in a pending United States patent application. In short, the Control device offers the possibility of storing pattern data in a memory device, for example a magnetic disk memory, to collect, further a device for retrieving the stored information from the memory and a further device to deliver this information to the correct electromagnetic drives located on some of the material feed plates or locks to thereby cause the correct needles to knit or not to knit, such as this is necessary in order to knit or knit the pattern represented by the stored pattern data or, to knot o The sealing egg of the type according to the invention supplies the knitting machine control with position signals, to enable the controller to retrieve the correct part of the pattern data from memory at the right time and guide him to the right locks and drives. These signals contain the rotary position of the knitting machine with regard to a reference position in units of needle distances as well as several multiple needle distances to which a relay, a byte and a lock distance belong · The knitting machine revolutions are also displayed, and the number of revolutions displayed once between the appearance of the reference position can be selected to include several pattern types and To match pattern heights.

Circular knitting machine with 1872 needles and 36 locks «, As the knitting machine axis turns, each needle is brought into operational connection with each of the locks in turn « On every lock every needle must knit or not knit ", D, Iu, it must move up to the knitting position and take a new loop or stay below the knitting position and none create a new loop. The term "knitting" used here includes "folding", whereby a new loop is created, without the old noose being thrown off,

There are cam tracks on every lock standing cam feet on the needle sleeves and selector sleeves to » work together to raise the needles to the required height ^ The needles are used for knitting or Miolit knitting by electromagnetic Drives are selected that either come into engagement with a selector foot on a selector sleeve, in order to thereby enable it Cause cam root to enter the non-knitting cam track, or who do not intervene with the voter foot ^ so that the cam foot enters the knitting cam track «, thus must, since 1872 needles and 36 locks in the depicted Knitting machine are available, 36 χ 1872 or 67 392 knitting » and non-knitting commands the drives at each revolution of the Knitting machine «. If the illustrated knitting machine works at 24 revolutions per minute, then require the drives about 27,000 knitting and non-knitting commands per second. Although this is not a large amount of data transmitted or speed for digital electronic computers, it is quite a large amount of data to be transferred for the interface to a mechanical device, for example a knitting machine “The closure egg according to the invention enables the handling or »processing of the necessary knitting and non-knitting information with the necessary Data transmission speeds with a considerably lower amount of electronic manipulation and thus a higher degree of profitability than could otherwise be achieved so far «,

3Q9318 / GS38

As detailed in the above-referenced copending United States patent application, the pattern data is stored in nine tracks on a magnetic disk. Each track is divided into four zones. One zone stores all pattern data for a lock for a complete pattern. An arbitrary pattern size of 208 stitches wide by 216 rows of stitches was used for the illustrated knitting machine. Thus, since there are 1872 needles around the cylinder, the pattern is knitted so that it appears nine times around the circumference of the finished sole. However, the number of turns required to knit the 216 rows of stitches of the pattern height depends on the type of pattern that is being knitted. For example, eiqfureifarbiges, planar pattern requires three Sohlösser per stitch row ₀ Therefore, the machine of the embodiment knitting 12 rows of stitches per revolution and revolutions required 18 to knit stitch rows 216. For a pattern that only needs two locks per row of stitches} the machine knits 18 rows of stitches per turn and would get by with just 12 turns to knit 216 rows of stitches «,

In both of the above examples, the pattern would then be knitted nine times over the required number of revolutions will. This applies to all patterns with a width of 208 stitches that are knitted on the machine shown «In other words that is, the stored pattern data is rotated for the number of revolutions required to knit 216 rows of stitches used nine times.

The four zones of each data track on the magnetic disk are divided into sectors so that each sector has all of the knitting data contains which are required for a lock for a full row of the pattern. A pattern width of 208 stitches was chosen each sector must contain 2108 bits of data. There is a lock on the same row of stitches in the pattern one full turn

309818/0838

the knitting machine knits, "see the present Embodiment repeated the pattern nine times; a new sector address is required only once per revolution However, sector-coming information is used during the revolution used nine times «Speed and sector address are used by the sealer egg and its associated translator clialtwng generated.

Due to the operating speed of the electromagnetic drives, the task of controlling the needles on each lock is divided among 13 drives.

A large ring gear 31 attached to the lower part of the knitting machine or the needle cylinder is attached, drives a pinion gear 22 on the input shaft of the optical Rotation encryptor 25 is mounted, which is attached to the frame of the knitting machine 10 in any suitable manner · When the knitting machine cylinder rotates, the ring gear 21 drives the pinion 22 to thereby drive the input shaft of the shutter of the s 35 in rotation «,

Inside the locking egg 25 there are two code disks, namely a fine code disk 27 (Fig. 3 and 4) and a coarse disk 28 (Fig. 6). The Feincodesoheibe 27 is open a shaft rotatably mounted, which is coupled to the input shaft 26 via gears, so that the fine code disk 27 is at every turn of the knitted needle cylinder by three full Turns. The coarse code disk 23 is on a Well © rotatably mounted via gears with the fine code disk shaft is coupled so that the coarse code disk 28 performs a full revolution for every 216 fine code disk revolutions; i.e. one full turn every 72 knitting machine cylinder revolutions «

Each of the encryption disks 27, 28 is provided with several code tracks with which several photocells work together to generate several binary coded electrical signals. These signals can either be used directly or treated logically to generate further binary coded signals and thereby the necessary To create synchronization information and position display information for the knitting machine control. It is not necessary here to describe the relationship between encoding disks, light disks and photocells in detail, since these details are known per se, _etc.

Fig. 2 shows very generally where and how a locking egg fits into the entire knitting machine and knitting machine control and works with it. The circular knitting machine, including its drive _s, its locks, cylinders, etc., is represented by block 31. Many of the binary electrical signals generated by the encryptor 25 are treated logically by the translator circuit 33 to create derived signals to retrieve correct knitting data from the storage device, for example a magnetic disk memory, and to generate the correct knitting and non-knitting signals for the lock drives in block 31, It goes without saying that the description given above about how the prior keyer of the type according to the invention is incorporated into the Overall control fits in, is very brief. Overall control is described in detail in the pending USA patent mentioned at the beginning, which dealt with knitting machine controls

A additional monostable multivibrator 51, which generates a short output pulse each time the signal in the Line 50 changes from 1 to 0 can be used to control the To shift shoe lock control shift register as a function of time on the rotational movement of the needle cylinder, as shown in the above-mentioned US patent application is explained in more detail.

In order to generate an activation signal for each of the 13 drives on each lock, it is necessary to set up a drive or To form needle counting number, which indicates which of the 13 needles in each season is to be controlled next. To such a To create a display, a second code track 55 is provided on the fine code disk 27. This code track 55 1st in 24 translucent and divided into 24 opaque code zones, each of which has a tangential length substantially equal to corresponds to 13 code zones of the fine code track 40 (24 χ 13 = 312). 13 photocells 56 are arranged so that they read the second code track in a staggered or phase-shifted manner to produce 13 output signals shown in FIGS. 4 and denoted by B, C, D, E, F, 6, H, I, J, K, L, M and N.

The signals coming from the 13 photocells 56 are logically combined in accordance with the Boolean algebra equations of Table I to thereby generate the drive activation signals EO-E12 to generate which correspond to the number of a drive that is to be activated according to a pattern signal that of a suitable Storage device is supplied, which is not shown here, but in the patent application mentioned at the beginning fully described 1st. Since each opaque and translucent zone of the code track 55 has 13 needles and d # »

309810/083 «

corresponding drives, each of which must be activated in order to knit a selected pattern, 13 activation signals E0-E12 are provided for each opaque and translucent zone of the code track 55. The real decryption circuit is shown in Fig. 5, in which each photocell 56 is connected to a converter 57 to convert the signals S, ü, B, i, F, S, S, T, 7, K, E, 3 and S. as well as the signals B, C, D, E, F, G, H, I, J, K, L, M and N to generate.

To generate each activation signal EO-E12 for every light-transmitting and Lich $ impermeable zone of the code track 55, the photocells 56 are 5 connected in pairs, when the front photoelectric cell of such a pair is located by the logic circuit of FIG _e next to a lichtundurohlässigen zone ₉ and the rear photocell next to a translucent zone, an activation signal is generated Photocells B and M an activation signal EO by combining A, S and M in an AND gate 58, by combining A ₈ B and Sl in an AND gate 59 and by combining the output signals of AND gates 58 and 59 in one ODEK gate 60 generated. This is done according to the Boolean equation EO = A 5 M + AB M. In a similar manner A, C, U, K ₉ C and N are combined in AND gates 61 and 62 and the OR gate 63 in order to generate the activation signal El in accordance with the Boolean equation EIsA, C il + Ä Ü N.

Since in the above-mentioned patent application there are 26 bits in a byte in the selected cough data format, it is necessary to generate 26 discrete control signals in order to transfer each pattern data bit from a 26-bit shift register to one of the 13 drives. One way of achieving this is to create an additional signal which is at logic 1 during alternating needle gradients each of which has a tangential length which is essentially equal to 26 code zones of the fine code track 40. Photocells 65 are arranged at 90 ° or 6.5 fine code zone tracks on phase in order to read the code track 64 and thereby generate output signals which are designated with 0 and P «, converters 66 then generate the signals u and P ₀

It should be noted that the start and end points of a row of stitches lengthways a roughly cylindrical tube of knitted material are offset by a number of rows of stitches that correspond to the number of lock groups is equivalent to. Therefore the pattern alternation runs in a straight line over the knitted material tube

A lock count that indicates the lock in which the first needle is on the needle cylinder and the change point is transferred from the translator 33 to the lock controls 34 transferred to generate a lock number that changes with the movement of the pattern change point and the first on the needle cylinder The needle located from lock 0 to lock 35 changes with each revolution of the needle cylinder, the Feinoodesoheibe has three additional code tracks 81, 82 and 83 · In this context is based on the change in scale in Fig. 4 between the code tracks 64 and 81 pointed out «. The code track 81 is opaque in seohs and six translucent code zones evenly divided Da the fine code disc with every third rotation the knitting machine makes one revolution, and there are 36 locks and 52 needles per lock are arranged on the knitting machine, One code zone on track 81 corresponds to a lock on the knitting machine and 52 zones on track 40, the code track 82 is divided into two translucent and two opaque zones, with the opaque zones twice as long are like the transmissive zones and alternate with the light transmissive zones as shown in FIG. Consequently an opaque zone of the code track 82 corresponds to four locks and a translucent zone corresponds to two locks. The code track 83 is divided into two identical code zones, namely a permeable and an impermeable each zone the code track 83 corresponds to six locks, front and rear

30981 8/0838

Photocells 84 are arranged in the manner shown in FIG. 4 and cooperate with the code tracks 81, 82 and 83 in order to generate binary coded signals FlD, FiG, F2D, F2G, F4D ₀ FhGt ₀ FOB and F6G

The front or leading photocell (D) of each pair of photo ropes is arranged in this way; that it reads before the actual transition point, while each rear or trailing photocell (G) is arranged in such a way that it reads after the actual transition point. Holding backwards or holding back and forth is done by the AND gates 84, 85, 86 and 8? and ODEE gate 88, 89, 90 and 9i "in the in Fig. manner shown 5 are connected · The signal EBL supplied directly to one input of each AND gate 84G, S5Gj ₁ 86g and 87G, to activate these gates as soon as EBl is at logical 1 during odd bytes. The signal EBl is fed to one input of each AND gate 84D, 85B, 36D and 87D via a converter 92 in order to activate these gates as soon as EBi is at logic 0 during even bytes its accuracy depends, and since the Α signal has an accuracy of approximately l / iO needle position, by using the byte signal to control the switching back and forth of the photocells 84 binary-coded signals EF1, EF2, EF4 and EF6 are generated, which start with 1 , 2, 4 and 6 are weighted and show lock numbers from 0 to 11 with an accuracy of 1/10 needle position.

For each needle cylinder revolution, socket numbers 0 - 35 To create the lock numbers 0-11 are generated three times. D.ho, during a first rotation of the finecode disk 27 the code tracks 81, 82 and 83 are decrypted to get the Display locks 0-11. During the next revolution will be

it decrypts _y to display locks 12-23. During the third turn, they are decrypted to reveal locks 24-25. The coarse code disk 28 is associated with the fine code disk 27 to provide the necessary information as to which series of lock numbers is being generated at any given time.

Whether the code tracks 81, 82 and 83 are to be decrypted as locks 0-11, 12-23 or 24-35 is determined by signals that are generated by code tracks on the coarse code disc 28, which are combined with the fine code disc 27 via a transmission device in one Transmission ratio of 2l6il is coupled, so that the coarse code disc rotates once every 216 revolutions of the fine code disc D ₀ h _OJ the coarse code disc rotates once every 72 revolutions of the knitting machine. The coarse code disk 28 has seven code tracks ₉ which are arranged concentrically similar to the code tracks of the fine code disk 27, as shown in FIG The code track 83 of the fine code disk 27 shown in FIG. 6 is shown at the head of FIG. As already mentioned, each of the zones of the code track 83 corresponds to six locks. The numbers located immediately below the code track 83 in FIG.

To enable signal EF12 at lock numbers 24-35 during one revolution of the needle cylinder and for the immediately following lock numbers O-il bei To remain logical after the next rotation of the needle cylinder, the code track 93 has 72 opaque zones, the one during the lock numbers 24-35 of the one needle cylinder revolution and during the lock number 0-11 of the next needle cylinder revolution Can be read by photocells F12D and F12G During the lock numbers J2-23 of the next needle cylinder revolution If, however, the signal EF12 is at logic 1 *, the code track 93 has 72 light-permeable zones (in Fig. shown hatched), which are read by the photocells F12D and F12G during the lock numbers 12-23. The translucent Zones of the code track 93 are half as long as the opaque ones Zones.

The EF24 signal remains on during lock numbers 0-23 logic 0 and is at logic 1 during the lock numbers 24-35. Thus, the signal EF24 switches to logic 1 as soon as the signal EF12 switches from logic 1 to logic 0. Corresponding the photocells F24D and F24G read a transparent zone of the code track 93, immediately after this from the photocells F12D and F12G has been read.

the activation signal for the AND gates 112 and 115 is generated. Thus, if EF6 and EF12 are both logic 1s and gates 112 and 115 prevent logic 1 signals from appearing at C-in, Bl, Bk and ΒΘ, then EF24, evaluated 24, is connected directly to A8 and Al6 , and therefore a logic 1 signal from EF24 contributes 2k to the sum S. The sum appearing at the connections S1-S16 and at C-aus shows the knitting machine bottom lock count in normal binary calculation. The Schloßzählzahl-digit signals are designated Fl, F2, Fk, F8 and F32 FL6 _9, wherein the numeric portion of the designation indicates the numerical value of the clock signal.

The Schloßzählzahl is provided by the translator 33 to the lock control 3k and serves to generate a Sohloßversetzungszahl that before the Musterweohselpunkt directly enters a lock, from logic 0 NaOH logically pushes "The operation of the lock control 3k se, forms no part of the present invention and therefore has not been fully described. However, it is explained in detail in the parallel US patent application mentioned at the beginning.

It is believed that the knitting machine 10 will be used to knit many different types of patterns, for example two-tone, three-tone or four-tone flat patterns or one-tone, two-tone or three-tone bubble patterns (openwork Pattern.) To enable the machine 10 to knit these different patterns, there are 36 locks in themselves As is known, provided in groups of two, three or four locks, depending on the one to be striokenden Template. Assuming a constant pattern of 216 rows of stitches, the number of turns that are required depends to knit a pattern, depend on the number of locks in each lock group. So are for a pattern with one lock in each lock group six turns of the

Needle cylinder required to knit the pattern «For A design with two locks in each of 18 lock groups requires 12 revolutions of the needle cylinder to complete the design to knit · Similarly, a three-lock group pattern is knitted in 18 turns of the cylinder or in four lock group patterns during 24 cylinder revolutions

In order to generate the repeated speed counting signals, the code track 94 is evenly divided into 36 translucent and 36 opaque code zones of the same tangential length, which are arranged alternately along the code track. Front and rear photocells 120 which read this code track are switched by the EF6 signal in the same way as the signals from the photocells 101, thereby causing a signal ER1 to change per revolution of the knitting machine. Thus, the REl signal sls acts as the single digit signal for a binary coded series of signals indicating the speed _o The additional binary coded digit signals for displaying the speed are generated by the code tracks 95-99 and by the photocells 121-125, as shown in FIG Fig «6 and is shown. All photocells 121-125 are arranged in back and forth switching pairs or lead-lag pairs to generate the signals R2D, R2G, R4D, R6D, R6G, R6 / 3D, R6 / 3G, RI2 / 3D, R12 / 3G, R12D To generate R12G, R24D and R24G «These signals are connected to the AND gates 128, which are switched by the ERl signal in the same way as the signal EF6 switches the signals coming from the photocells 106 and 120 Gates 129 combine the & signals coming from the AND gate pairs.Since the ERl signal is switched by the EF6 signal, which in turn is switched by the Α signal, the resulting revolution counting signals ERl, ER2, ER4, ER6, ER6 / 3 ₉ ERI2 / 3 and ER12 maintain 1/10 needle position accuracy The exact table for these signals is as follows:

To achieve a revolution count that cycles through six revolutions at a time, creating a 2i6 row of stitches pattern to knit which requires only one lock per group, the selector switch 133 (Fig. 7) is set to position X6. When the selector switch is in this position, only signals ER1, ER2 and BR4 are used to repeatedly count 0 to 5 required. Thus, at the sixth, twelfth, eighteenth, etc. needle cylinder revolution, the signals ER1, ER2 and ER4 logically linked in order to display the revolution 0 as soon as the selector switch 133 is in position X6 is located.

A revolution count, which is repeated cyclically within twelve revolutions, is required in order to achieve a To knit a 2l6-row pattern that requires two locks per group. To achieve this, the selector switch is used 133 set to position X12, and the signals ERl, ER2, ER4 and ER6 are then used for repeated counting from 0 to 11.

If the selected pattern requires three locks per group, the selector switch 133 is set to position X18, to thereby the signals ERl, ER2, ER4, ER6 / 3 and ERl2 / 3 combined to create a revolution count or to be linked, which cycles through 18 revolutions. It should be noted that the ER6 / 3 signal is used earlier was called the ER6 signal. This is because the repeated counting to 18 requires that the signal, which one Evaluation six is given, for the cylinder revolutions 12-17 is at logic 0 during a counting cycle and for the revolutions 0-5 of the next counting cycle remains at logical 0. Because the ER6 signal has its logic value every six revolutions must change so that this signal is used for a revolution count can be used, which cycles through twelve revolutions,

30981 8/0838

this signal is suitable for use for a revolution count only unsatisfactoryι which cyclically runs through 18 revolutions.

Finally, when a 216 row stitch pattern is to be knitted for ₉ that requires four locks per group, the selector switch is set to position X24. This setting of the selector switch results in the signals ERl, ER2, ER4, ER6 and ER12 being used to generate a revolution count that cycles through 24 revolutions.

7, the signals ER1, ER2 and ER4 are connected to the A1, A2 and A4 terminals of a binary full adder 131 which is identical to the adder 111 and has terminals labeled in the same way as this. A multi-position selector switch 133 has a sliding contact 132 which is connected to a voltage source -JV which represents a logic 1 signal. Each of the connections of the switch 133 can be connected to the ground (logic 0) through a resistor Vbh in order to ensure that a logic 0 signal appears at it whenever the sliding contact 132 is rotated to a different position Connections are designated with X6, X12, X18 and X24, whereby their numerical part shows the number of revolutions per pattern cycle

The logic circuit for controlling the speed signals ERi, E «24 is complete in the circuit diagram of FIG and therefore does not need to be described again here in words. By turning switch 133 various combinations of AND gates with selected signal pairs of the Signals ER6, ER6 / 3, ER12 / 3 and ER12 with the adder 131 g'e-

3Ö9818 / Ö838

forms. An optional translator circuit for use the signals ER24 and ER48 is not shown in Figure 7, but the translator circuit shown can easily be expanded, to include these signals. For example, ER24 would have suitable gates, which are triggered by an additional Connection to the switch 133 are activated, optionally connected to A8 and Al6 of the adder 131, thereby to the appropriate time to contribute to sum 24.

Two translator configurations are described in detail for purposes of illustration. In the first configuration it is located the switch 133 is in the X6 position, and there will only be the AND gates 141 and 142 activated by the output of the converter 140, which is at logic 1, since the output of the AND gate 139 is at logic 0. The output of the AND gate 139 can only be logic 1 if the Switch 133 is in the X24 position. However, since the AND gate 143, 144, 145 and 146 are not activated, the adder 131 does not receive any signals other than ER1, ER2 and ER4 " Accordingly, the output of adder 131 is a normal binary number that runs from 0 to 5 and repeats itself. These turn signals are assigned to the lock controls 34 in the manner as they are pending in the already mentioned several times USA patent application is described in detail, thereby creating a selected pattern after every six revolutions of the needle cylinder to repeat «,

When the switch 133 is in the X18 position, as is apparent from FIG ₀ 17, the AND gates 144 and 145 are activated to the ER6 / 3 and ER12: 3 signals therethrough permitting the adder 131 * The non- activated AND gates 143 and 146 prevent the passage of the signals ER6 and ER12. That

309818/083 $

Signal ER6 / 3 is passed through AND gate 144 and the OR gate 147 connected to B2 and thus via the @ OER gate 148 to B4. So if ER6 / 3 is logical 1, B2 and B4 are also logical 1, which adds six to the adder output » In a similar way, the signal ERI2 / 3 is via «Yes AND gate 145 and OR gate 149 connected to B8 and thus via the OR gate 148 to B4, thus if see the signal ER12 / 3 is at logic 1, then become the output of the adder 131 twelve contributed. Since ER6 / 3 and ESI2 / 3 never both at the same time are logical 1, both signals can be connected to the B4 connection of the adder 13i.
