In known devices with electromagnetic control of the reading elements, through which, for example, the drop needles for setting the punch of an impact machine or the Circuit boards of a jacauard machine are adjusted accordingly, Plunger magnets are used that either pull or push. These plunger magnets have the Disadvantage that only small lifting forces and small strokes can be generated with them. In the case of impact machines or jac-

: Quard machines similar conditional dense arrangement of magnets only very small coils can be used. With these small coil dimensions, however, only very small Forces for the attraction of any soft anchors or the like are generated, so that these systems do not work reliably. Except-

Cl ' if.

These are, as can be seen, for example, from German patent specification 1 535 930 ' ¹ ' , mostly very complex mechanical connecting devices and guides between the plunger armatures of the magnets

and the reading needles are required. In addition, there is magic in these
Had the disadvantage that prolonged operation, as is often required by the fan movement of the machine, heats up very much. In addition, a very large power requirement is required with parallel control.

The invention is based on the object of eliminating these disadvantages of the previously known devices, the operational safety and to increase the reliability of the magnetic control of the reading process and a magnetically controlled and actuated To create reading device that works less prone to failure than the previously known devices and yet constructively

tiv is relatively easy to carry out, so that the performance increased, the cost of production kept low and the sources of error and malfunctions during the operation of the system can be reduced.

This object is achieved according to the invention in that initially by an external force coupled with the machine drive, all; * 'magnets and armatures are independent of one existing magnetization according to the distance moved relatively towards each other and pressed against each other to form a contact whereupon there is a reversal of the movement, in which the anchor depending on the existing Magnetization can be moved or not. So there is no magnetic force for the approach of magnet and armature as is well known, with increasing distance νοΰ magnet and anchor very much strongly decreases, to apply, but only for the clinging to one another. In the invention, magnets work as holding magnets, so that even with low magnetic or electrical forces Performances comes from, so that small-volume magnets are used and still work strokes of any size can be carried out can.

In a further development of the invention it is provided that all Movements carried out when the magnets are in a magnetically effective state and that the magnetization for individual magnets is only canceled afterwards in accordance with the reading instructions. As can be seen from the following, this measure enables

lent, the advantageous of permanent magnets, whose magnetic

309885/0201

can be canceled by a corresponding counter-excitation. According to a particular variant of the invention the magnetization of the individual magnets is thereby serially 'canceled, whereby the energy expenditure for the electromagnetic Control is decreased. '·.

A reading device for carrying out this according to the invention The method has a number of anchors connected or connectable to a reading element or the like, the electromagnets assigned in each case relative to an ftm are designed to be movable around a certain Wegstreffke. in the in general, there are 1344 read-in elements accordingly the number of holes in the commonly used control cards, and thus a corresponding number of anchors and magnets. As part of According to the invention, the individual read-in element can of course also form the armature for the magnet.

The essence of the | reading device according to the invention consists in that at least one organ acting jointly on the magnets or on the armatures is provided, which is supported by a the drive coupled to the machine can be moved back and forth according to the distance and by the armature and magnets to be moved towards one another? and can be pressed together. The establishment of the contact between armature and magnet is thus through mechanical and no longer caused by magnetic forces, so that the aforementioned advantages such as compact space and power requirements, Working strokes of any size and, above all, operational reliability and fast working can be achieved.

In a particular embodiment of the invention is provided that the magnets are designed as permanent magnets and have a winding for demagnetization. In particular, this exemplary embodiment offers a simple way of controlling the magnets in series by means of short-term control pulses which are dimensioned in such a way that they cancel the magnetization through the counter-excitation and the Waste: the armature cause or temporarily prevent the armature from sticking to the magnet. This makes a considerable Energy savings achieved. The lifting movement of the reading elements can take place in the de-energized state. Particularly The control of the magnets can be advantageous here with the aid of electronic control circuits known per se perform as disclosed, for example, by German Offenlegungsschrift 2 016 94-5.

According to a further development of the read-in device according to the invention, the magnets are fixed above and next to one another in a frame that can be moved back and forth by the machine drive according to the arrangement of the read-in elements, the read-in elements each having an armature at their ends facing the magnets and with a return spring or the like . are provided. In a particular embodiment, half of the magnets, that is to say for example 672 magnets each, are arranged in one of two frames that can be moved in opposite directions from opposite sides to the reading elements assigned to it. "This arrangement of the magnets in compact blocks which are summarized in a framework that provides the XQfiS.iJ-». ^That the same very easy to remove

are to be changed, i.e. the individual frames or blocks can can be removed very easily, as the magnets have no mechanical connection to the read-in elements. On the one hand The simple removal of the magnet blocks facilitates a quick check and correction of errors in the reading unit, and for the for others, assembly is very much easier when assembling the machine. In the context of the invention, the anchor to the Read-in elements are resiliently connected to the read-in elements when they are pressed, so that upsets when pressed excluded are.

In another embodiment of the invention can the magnets can also be arranged in a stationary manner, because the organ that can be moved back and forth engages the anchors, which then naturally go through this organ are designed to be movable accordingly. In a special variant of the example is also still provided that a releasable by pressing the armature against the magnets coupling between armature and reading element and another reciprocating organ are provided through which the read-in elements connected to return springs are in one position can be moved to engage the clutch. Such an arrangement is advantageously suitable for controlling the boards of a Jacquard machine.

In the context of the invention, however, it is also possible to special To do without sinkers and the hooks to be lifted by a knife bar or the like of a jacquard machine as read-in elements to be provided on which the harness cords or braids hang,

With a resulting spatial distribution of the Reading elements the invention provides that the magnets on a back and forth movable frame, beam or the like. Correspondingly the spatial distribution of the read-in elements are arranged, so that all magnets simultaneously during the lifting movement can be brought up to the reading element assigned to them.

In general, you have a very large number of To do magnets in a certain way, e.g. in 84 groups of 16 magnets each or, more generally, in m groups of η Magnets are arranged. To control and operate such a large number of magnets in the largest possible number, see the invention provides that with m-n magnets each magnet in series with a blocking diode at one end of the winding at one of m Lines in the x-coordinate direction and at the other end of the winding on one of the η lines of the y-coordinate direction of a known Sohaltmatrix is connected, which accordingly different potentials, e.g. positive or negative, can be fed to the read-in instruction, whereby the lines at least one coordinate direction can be controlled serially to the desired potential value, e.g. by a shift register or the like. Against such a circuit can The reading can be carried out in a few milliseconds with low switching power, especially when permanent magnets are used, the excitation of which is only briefly canceled against a short pulse one after the other.

devices for controlling a jacquard machine.

When in the upper half of the Pig. 3 illustrated reading device are on "both sides 84 adjacent rows of eight magnets on top of each other 1 arranged in a frame and firmly connected to this. The frames 2 are with the machine drive in a suitable, Connected in a manner not shown here, so that with each reading process a reciprocating back and forth movement in a horizontal direction Rioh ^ ung can perform according to the arrows χ. The poles the horseshoe-shaped magnets 1 are each one end of a reading element 3 between the two frames 2 located reading mechanism facing. The reading elements 3, which in the example shown here as narrow, elongated, in slides movable in the horizontal direction are also in the form of 84, each lying one above the other in a plane Groups of 16 elements arranged. Each reading element 3 alternately has an armature 4 at one end, to which a magnet associated with it is one of the frames 2 opposite, one on and at its other, opposite end Return spring 5. In the spaces between the individual groups of sixteen of the read-in elements, each lying in one plane 3 there are sixteen of the flat Pallnadein each 6, which hang in a grate 7 that can be moved up and down according to arrow y. These Pall needles 8 have laterally outwardly projecting Pin 8 with which they can rest on the reading slide 3. Here are the pins 8 of the first eight Pall needles directed to one side and those of the other eight pall needles to the other. -. . ·

At the beginning of the reading movement, the slide 7 with the drop needles 6 attached to it is moved upwards. The two frames 2 with the magnates 1 are simultaneously inwards, i.e. in opposite directions, moved until the magnets 1 strike the armatures 4 of the reading elements 3 assigned to them and against them be pressed. The armatures 4 are on each of the total of 1344 read-in elements 3 against the action of a spring 9 slidably mounted (Fig. 1 and 2). When pressing the magnetic frame 2 against the read-in elements 3 from both sides, the armatures 4 assigned to them are on both sides slightly resiliently pushed back. The built-in Druokfedrn 9 in the anchors 4 ensure that they attach securely and parallel to the adhesive surfaces of the magnets 1. Then become the frame 2 is moved back over the machine drive by the same distance in the opposite direction.

On the return path of the magnetic frame 2, those read-in elements 3 and their armatures 4 are held in place by the magnets 1 assigned to them and is taken along, pulled against the force of the spring 5 to the right or left. With the then subsequent When the grate 7 is lowered, the dowel pins 6 are supported with their pins 8 depending on the position of the reading element assigned to them 3 either on its upper edge or they fall if the reading element assigned to them is not from its magnet has been held and taken into the recess 9 of its reading element 3 provided for this purpose, whereby Lower the corresponding push needles in the pushing needle unit 10 of the impact machine located below.

As can be seen from Fig. 1 and 2, the magnets 1 can

probably a flat 0-. or W-shape and either as a pure electromagnet, which only becomes magnetic when current flows through its winding 1b, or as a permanent magnet be formed, which is provided with a winding 1a, through which a gene excitation is generated when current flows through can be, through which the magnetic effect of the permanent magnet is canceled.

When the magnets 1 are designed as permanent magnets according to FIG. 1 all read-in elements are taken along on the return path of the magnet frame 2 after the magnets 1 have been pressed against the armature 4. When you take the reading elements with you, the return springs are tensioned. The final position of the frame 2 after performing the The back and forth movement is the read-in position, i.e. the machine has made one revolution and is now at a standstill. In this Position, the reading takes place by brief blessing-r ' excitation of the magnets 1 according to the reading instructions, so that the corresponding reading elements 3 under the action of Springs 5 zor ^ f * - quick and thus read. she Reading takes place serially and can be carried out very quickly using electronic switches. As can still be seen from Fig. 4, a group of sixteen will follow with the electronic reading the other switched. It works with the reading device shown always a group of eight from the right and one group of eight from the left side, i.e., with one All magnets of a group of sixteen are to be de-excited according to the reading instructions simultaneously de-excited. The electronics then continue to switch on

Fig. 4 shows a known switching matrix through which the windings 1a of the magnets 1, each of which is preceded by a blocking ode, from a control circuit 11 from mi% -help a shift register 12 can be controlled and excited in the respective desired W ^ ise. The 16 power amplifiers 13 there is one for each magnet due to the read-in instructions Group of sixteen specific potential applied to one end of the winding and then, controlled by the shift register 12, by the output stage of the 84 output stages 14 assigned to this respective group of sixteen via the locking electrodes 15 positive potential is supplied to the other end of the winding of the magnets to be de-energized in this group of sixteen.

A group of sixteen is read in at one speed of only a few milliseconds, so that all 1344 electromagnets are read in in a very short time. Advantage-

Luckily, the magnets can also be fixed with interchangeable Contact field or contact plate be connected, wherein the contact connections between the magnets can be repositioned. The contact fields or plates are installed between the control matrix and the magnets. This enables the read-in commands can be transferred from the electronic control circuit to any selectable magnets.

The solenoids can also be operated via an electroraechanical

reading work, as it is e.g. in the German patent specification 1 535 930 ", can be read in. With such an electromechanical read-in, however, no high Reach read-in speeds.

The activation of the holding magnets can take place not only in series but also in parallel, so that all magnets are activated and excited at the same time. Here, however, a correspondingly higher circuit complexity, for example 1344 control wires instead of, as in the circuit according to Pig. 4, - only 100 control wires required. The parallel operation is also "However, the Einleseerregung is carried out with the electromagnet shown in Fig. 2 in the illustrated retention device can be carried out. Here, the arranged in the magnetic frame magnets 1" before the start of the reciprocating motion or at the latest during the pressing of the magnets 1 in the A _n ker 4. When moving back to the basic position, the reading elements corresponding to the non-excited magnets are not taken along.

After reading, if the needles 6 accordingly the position of the respective read-in elements 3 have fallen off and those connected to the lower droppins 17 attached at 16 Pushing needles 10 have lowered accordingly, they are pressed off by the knife frame 18 in a known manner, so that over the transfer ram 19 through the punch 20 the card 23 running over the cylinders 21 and 22 is punched accordingly. The contents of another card 24, e.g. Binding card, can be added by scanning with the lower

Falling pins 17 are transferred to the card 23.

After the card has been punched, the next reading process takes place, previously the read-in elements 3 taken along by switching off the excitation or de-excitation of the magnets to waste are brought so that they are withdrawn under the action of the springs "5 in the stop grate 25 in their initial position. .

Fig. 5 shows an embodiment in which a Reading device, as it is already shown in the upper part of FIG. 3, it is possible via different needle systems 26, 27 and board systems, which are connected to other control slides 30 via strands, the punch for To influence cardboard cards. This can also be of an endless Paper cards are copied to cardboard card systems.

In this embodiment are the armature 4 is designed as a pawl pivotable about the axis 33 against the force of a spring 34. Similar to that earlier example of the magnetic frame 2 in this embodiment a bar or frame 31 is moved back and forth according to arrow χ, which with suitably trained drive chains 35 the armature 4 presses against the magnets T, which, depending on their state during the return movement of the frame 31, the armature 4 hold on or not.

⁵ ~ 309885/0201

The pivoting armature 4 have, as in Pig. 6 clearly recognizable, on its facing the associated read-in element 3 End of a nose that with a corresponding nose at the end of the reading element 3 is a latching lock or forms a releasable lock with this. Since the coupling is released during the pivoting movement of the armature, © inen second, according to arrow x * back and forth movable bar or frame 32, each with impact webs 42 on one ent-. speaking nose 41 of each Einleseele'mentes 3 engages, when pressing the armature 4 through the pressing webs 35 each Read element 3 pulled so far to the left or right outside by the force of the return spring 43 at the same time that, if the armature assigned to it is not held in place by its magnet is, the read-in element by the action of the spring 34 during the return movement of the frame 31, 32 back- · pivoting armature 4 is held .. Those reading elements 3, however, whose associated armature 4 by his Magnet has been held in place when the frame 32 moves back against the stop grate by its return spring 4 44 drawn.

According to the so controllable by the magnets 1 Read-in position of the read-in elements 3 are the sinkers 38 of the jacquard machine, on which the "harness cords" in a known manner 39 hanging, pressed from the knives 37 of the knife box rising and falling in the known manner according to arrow y or not.

It can be seen that the reading device in this example can also be modified, for example by omitting it of the ratchet mechanism and the frame 32 armature and reading elements form a physical unit that, driven executes a linear movement of the frame 31 in the horizontal direction against the magnets.

Pig shows an example of the immediate, direct reading of the sinkers on a jacquard machine. 7. Here are the Reading elements formed by the hooks 3 * of the boards 38 », which, depending on whether they are at their base 4 * by the magnets 1 have been tightened or not, in their drawn down position remain or are taken upwards by the knives 37 of the knife box 36 rising and going according to arrow y will. In this embodiment, the magnets 1 are between the plates 38 extending webs or the like. A frame 45 is arranged, which is analogous to the magnetic frame 2 in FIG. 3 is moved back and forth according to arrow χ in the same machine cycle. The magnets are directly on here moved closer to the location of the boards to be controlled.

The basic idea according to the invention, the magnets no longer for Tightening, but only using it to hold your anchor, enables a much more reliable operation compared to the state of the art and faster work, with less space requirement, higher forces with lower power requirement (impulse operation) and any large working strokes can be achieved. Since here the magnets have no moving parts and with not mechanically connected to the read-in elements to be controlled
