Description

Control device for @;, irk or knitting machines The invention relates to a control device for ', 1'irk or knitting machines for controlling the for the production of one or more items of work required according to a predefined program, whereby for the setting of the various work steps of the program each switching sections are provided, the multiple switches for contain the setting of the work process and the 'aieder-LolLingen of the same, and furthermore, after the completion of an operation, switching over from a switching section takes place automatically on another.

A known device of this type (British patent 865. 364) an e @ ien counter is provided for each work step, which is determined by a previous set position with every full revolution of the main eccentric shaft of a plachulier knitting machine um 'ins is set back against Kull and when reaching' Mull an associated one Contact closes to excite a circuit. Are in this circuit pre-set switch-off switches, through their setting the desired f = work process is effected. is this on-site process according to the setting expired, the control is automatically sent to the next meter and its associated selection or multiple switches are passed on for the next work process and the process repeats itself again. The machine thus receives all commands which are required for the manufacturing process of a '.; aren piece. Everyone who needs to go before work So a switching section, which consists of a so-called row counter, an F1ö, frequency switch, with which the number of intermediate rows is set according to which a certain machine operation should repeat, as well as from one Function switch or form control, sehalter existed on which the to be exercised Operation is to be discontinued. It thus becomes the number of repetitions, the distance of repetitions and the operation of the machine to be repeated.

Thereby setting counters with differential mechanism are used for each work process used to set the number of smooth rows, and each of these setting counters a switching device is assigned to after the end of the operation on the automatically switch to next work step. can.

This arrangement not only has the disadvantage that expensive electrical components, such as these setting counters with differential mechanism and also the changeover relays, are needed in large numbers, which makes the entire device much more expensive if it is to be used for a large number of operations, but also a lot more space is required. Another disadvantage of the known advantages. It is correct that the setting counters are very difficult to use, because when setting the counters, you must first lock them with one hand and set the individual digits with the other hand. The transfer of the program to the many setting buttons and preselection counters takes a lot of time, so that downtimes can easily occur when the sequence of the last work steps leaves relatively little time for changing over the first work steps. With this setting method, errors can easily occur when the program is transferred. In order to avoid the large number of preset counters and also to enable preprogramming that saves pre-programming according to @ .asdhinenstaltzeit_, it has already been suggested instead by means of the preselection counter, the corresponding Prograirtr :: numbers and Functions - through - a ..hole - common with Jacquard-I, machines map of: to give up iaschne (british es patent 060.A6), the by appropriate abta: pins or photoelectrically disconnect geta.s: is switched.

According to the invention, this object is achieved in that multiple switches are provided for setting the number of rows and repetitions of the operation, any number of identical multiple switches being assigned one after the other to a single counting device. For the formation of multi-digit numbers, decadic multiple switches are combined to form a switch group. Furthermore, a single counting device, which advantageously consists of a read-out counter, can be assigned to any number of similar switch groups.

The use of readout counter% in connection with multiple switches instead of setting counters, because of their differences in terms of circuitry and great economic advantages. By using multiple switches and a single counting device for any number of counting devices results a substantial reduction in the cost of the device and a simplified setting through the multiple switches.

As a further improvement is according to a further feature of the invention a switching device assigned to all switching sections, which for similar Multiple switch each has a switching track. Furthermore, the inventive Device by connecting the multiple switches by so-called printed Circuits at any time in a simple manner any expansion of the switch groups or switch sections experience without the base unit with the associated Selection counters must be changed or also correspondingly multiplied. Of the Selection counter also enables a visual check of the current work status the machine. All multiple switches are expediently covered by a single program template, which * a simple pre-programming during allows the production of the machine. The program template can also according to the invention Have setting marks so that the multiple switches: schematically on these marks can be set without reading or putting together the correct numbers is required when changing programs. The setting marks can be used as an additional control as openings corresponding to the switch on the program template so that the program template can only be set up when the program is set the multiple switch is possible. Further details of the invention are based on of the drawings: FIG. 1 shows the control panel of the control device in FIG Connection with a piece of goods to be worked; Fig. 2 shows the program template in partial view; 3 and 4 show a switch button according to the invention in side view and top view ;.

Fig. 5 shows the electrical structure of the control device; Fig: 6 shows a switch plate according to the invention. Socket strip; -Fig.-@7 shows in the cutout the connection between plug-in. strip and switch plate In. Fig. 1 are the control panel 2 of the control device according to the invention and for example a pullover front part 1 .with a V-neck, which is made on a flat knitting machine manufactured should be displayed side by side to show the relationship between the settings the control panel and the parts to be worked on the front part of the sweater 1 closer to explain. The sweater front part 1 consists of differently shaped parts S1 'to S6' and from the parts SV1 'and SV2' of the V-cut, their desired Form is determined by the control device according to the invention.

The control panel 2 of the control device is divided into a switch field 3 'with the various multiple switches, a row of Control lamps 21 and the readout counters arranged in the lower part of the control panel ZR or: ZRI, ZH or ZH 'as well as ZRV or ZRV' and ZHV or ZHV '. Between the readout counters and the switch panel is a row of push buttons for special circuits, such as immediate Transition from one section to the other, reset the readout counter to zero etc. and the main switch 20 is provided for the control device.

The switch field 3 'is through the vertical rows of multiple switches divided into switching sections S1, S2, S3 .... Sn, each switching section one Control Zampe 21 is assigned, which lights up when the relevant section. is in action. According to the operations to be controlled, for example on flat knitting machines, the sections S are composed of three switch groups, namely from the Switch group ZSR for the selection of the number of rows according to which you see a specific function repeat or for: which it should last, the switch group, SH for the selection.

the number of times a particular function should be repeated and the switch group SP znr-selection of the desired function. D:, e = named i Switch groups usually consist of several multiple switches. For representation of two-digit numbers in the switchgroups ZSR and ZSH it is advisable to change to decadic ones Multiple switches used, with one switch ZSR1 for setting the diner and the other switch ZSR1 'for setting the tens serves. The subdivision of the switch group ZSH is analogous. Will be three digit numbers loading for programming. required, -so three decadic multiple switches must be in these groups should be provided.

For the function switch group SF it can be sufficient if only one Multiple switches are provided, depending on how many functions are running of the various work steps-are required. With the present control device, the one for a flat knitting machine for production. thought of outerwear is, for example, three function switches are provided. The multiple is: ch, schalt.er SFR -in each section for the deck movement on the right side and the multi-fold holder SFL provided for deck movement on the left side of the FontÜr.'Ferner is a .. third function switch SFU for further machine functions, such as "long row", "Hingel apparatus on", "kingel apparatus off", "V-neck start", "control drum" etc. determined. each - of the digits 0 to 9 in the lower row of switches - SFU - (Fig. 2) designates one of these functions. The functions. of the SFU switch are respectively Executed at the end of a-j.eden-Sektidn before moving on to the next section will.

In: jed.eT section S are the corresponding switchgroups with the multiple switches mentioned, so that n multiple switches for -n sections of a certain type are provided in the switch panel. The number of in the switch panel The sections to be provided depend on the size of the sequence, that is, the Sequence of operations that are to be carried out one after the other. At a If there is a sufficient number of sections, several items of goods can easily be placed one behind the other can be worked with a single program.

The switchgroups ZSR and ZSH, with which, as already described above, Numbers to be set is each one Readout counter assigned, which correspond to the switch groups for multi-digit numbers in the unit counter ZR resp. ZH and tens counter ZR 'or ZH' are subdivided. The number of times on a counter working switchgroups is arbitrary, so that, for example, the switchgroups ZSR1 to ZSRn only require a single readout counter ZR.

Sections SV1, SV2 .... SVn provided in the same Vi, eise as the sections described above S, and where the corresponding switch groups ZSRV and ZSHV in in the same way selection counters ZRV and ZHV, as already described, are assigned.

Fig. 2 shows a partial view of the program template 3, which on the switch field 3 'of the switchboard is placed in order to set the multiple switches. It has proven to be useful, the switch field and the program template accordingly set up in such a way that a single coherent program template covers the entire switch field covered. The program template 3 has corresponding to the switch buttons 4 of the Multiple switches, for example, circular openings, around the edge of which the Designations for the individual switch positions are attached. Otherwise correspond the rows of breakthroughs the switch groups and sections of the switch panel 3 'as described above.

The programming is carried out as follows: On the program template 3 the corresponding position is marked for each switch. That can be done by strokes or by snapping in Iviarken. The snap-in of brands offers in particular a control option for the right attitude the switch if the switch buttons 4 are provided with pointer lugs 41 (FIGS. 3 and 4) that fit into the snapped-in brands. The program template 3 is initially Pushed over the round part of the switch buttons 4 and then the switch the snapped-in brands. Are all switches set correctly, lets the template 3 is completely over the switch buttons 4 and the pointer lugs 41 push. Switching to a new program can take place while the the last sections of the previous program are still in progress. 14Tan begins set the first sections and converts the last sections as soon as they are according to the old program have expired.

Corresponding to the sweater front part 1 shown in FIG. 1 is for Work the straight section S1 'the section S1 to, for example, twenty-one Rows set smoothly: Multiple units switch ZSR1 is on "1;, the multiple tens switch ZSR1 'is on "2", the switches ZSH1 and ZSH1' are on "0", the function switches ZFR1 and ZFZ1 are on "G1.R.", that is, smooth rows, and the switch SFU1 is on "0" .. especially only the ZSR group is switched on, only the assigned Counter ZR or the tens counter ZR 'operated until the desired number of rows "21" is reached. Then it is automatically used for the next production step of the section S2 'of the sweater 1 switched to the section S2, the control lamp 21 of this section lights up and the set program for this section is running from and that again via the counter ZR or ZR 'and, since it is now expanded and the group ZSH is set, also via the counter ZH or ZH '. In the section S2 are, for example, the switch ZSR2 to "g", the switch ZSR2 'to "0", the Switches ZSH2 and ZSH2 'are each set to "2" and the function switches SFR2 and SFZ2 to "W", SFU2 to "0". That means that every time after nine smooth rows is expanded and this process is repeated twenty-two times. The counter ZH or ZH 'receives one after each further after the new smooth rows Pulse, while the counter ZR starts again at Lins. This process is repeated until the set repetition of "22" is reached. Then it will be changed to the next section S3. On this "quiet" are the set Go through sections S1 to S6 and work the sections S1 ', S2' to S6 '. Y While section S3 is only set to work on smooth rows, the switch group ZSR is open in section S4. four smooth rows set, being these four rows are to be repeated twelve times. Since the function switches SFR4 and SFZ4 are each switched to "M2", this means that after every four smooth Rows is reduced tweinädlig and this process should be repeated twelve times. The function switch is also located in section S4 for the start of the V-neck SFU4, for example, set to "2", which means that after .Ablauf the program the section S4 at the same time to the next following section S5 and the section SV1 for the V-neck part SV1 'is switched. The other sections are now running S5 and S6 as well as SV1, and 3V2 in parallel, but independently of each other.

You can use the control lamps and counters at any time to do this Check and track the work flow of the machine.

If it turns out that part of the front part of the sweater is too short or too long, for example by changing the switch ZSH3 the '#' repetition can be increased or decreased. By pressing the shift key 22 can also abort the program of a section and move on to the next section be passed over immediately.

The electrical structure of the control device according to the invention for the 1 @ anddecker is shown in FIGS. 5a to 5d, which together form a circuit diagram. The individual partial drawings each adjoin one another at the dash-dotted border line, namely FIG. 5b on the right follows on from FIG. 5a, and FIG. 5c on the left follows on from FIG. 5b and to the right of Fig. 5d. A control for the V-decker can be connected to FIG. 5d, which in principle represents a repetition of FIGS. 5a to 5d.

This Fij. 5a to 5d show, in addition to those already mentioned, on the switch panel 3 'visible switches and counters a switching device U, which mechanically is connected to the switches Un (dashed line). This switching device U is used to operate the switch Un, which moves from one section to the next, for example from S1 to S2 or from S2 to S3.

Each horizontal row of switches has a changeover switch U1, UZ ... Un assigned. In order to switch on a switching section S, all changeover switches must consequently U1 to Un are operated simultaneously and each assume the same position, which requires the corresponding gection. The number of switching positions of the Changeover switch U1 to Un corresponds to the number of sections S1 to Sn.

Roller switches, overdrive switches, for example, can be used as changeover switches Un or other electro-mechanically driven multiple switches or electronic ones U'atter be provided. -esoncters suitable as changeover device and changeover switch is for example a rotary selector, in :: elchem the individual. Toggle switch Un next to each other are fixed on a common shaft and by rotating the ", dent together Be made.

There are also diodes D1 to D5 instead. Blocking contacts provided, to avoid the impulse currents flowing in the wrong direction. That Relay A has three normally open contacts; the contact a1 is used to reset the Readout counter ZR, ZR ', the contact a2 prepares the switching of the switching device U J_ in front and the contact a3 serves as a pulse generator for the readout counter ZH, ZH ' and to control the function switches SFR1 to SFRn. The relay E also has three working contacts, with contact b1 for resetting the readout counter ZH, ZH ', the contact b2 for switching the switching device G and the contact b3 are used to control the function switches # SFU1 to SFUn.

Depending on the setting of the function switches SFR1 to SFRn, one of the command contactors FD to FH switched on, which is via their 'contacts Hold Fd to Fh yourself: Likewise, depending on the setting of the function switch SFU1 to SFUn switched on command contactors FK to FN from their contacts Pk to F-n held itself.

The command contactors FD to FN are deleted via the delete contacts Lö1 or Lö2. And the impulses for the readout counters ZR, ZR 'via a pulse generator J1, which at-. for example, actuated by cams on the main eccentric shaft will.

When a new item of goods is started, the switch Un the section S1 switched on. For the sake of simplicity, there are only multiple switches for the sections S1 to S3 and only the function switch SFR for the right side of the font.

From the pulse generator J1 of the machine, the Machine counting pulses given to the unit counter ZR of the control. By the switching device U the single multiple switch ZS @ .1 of section S1 is switched on via switch U1, to which the read-out tens counter ZR 'is connected via U1. This readout ten counter ZR 'receives via' a contact of the read-out single counter ZR after every ten Im-. pulse an impulse. Via the same switch U5 is the Zefiner selector switch ZSR1 ° connected to control relay A: Separate both readout counters ZR and ZR 'die have reached the number set in switches ZSR1 and ZSR1 ', the relay receives A voltage and switches the counters ZR and ZR 'to reverse with its contact a1, prepares with his contact a2. the switching device U before and switches with his Contact a3 via changeover switch U3 and via function switch SFR1, for example the function contactor FD, which has its own contact Fd and the reset contact Lö1 holds: This contactor now issues a corresponding command to the machine, which is deleted again by the machine via contact Lö1. Furthermore, over Contact a3 of the readout counter ZH advanced by one pulse.

The readout counter ZH or ZH 'is connected in the same way as previously described with its assigned selection switches ZSH1 to ZSHn or ZSH1 $ to ZSHnt via the changeover switches U2 and U6 to the relay B. When the number of repetitions set on switches ZSH1 to ZSHn is reached, relay B is also energized together with relay A, which in turn energizes command contactors FE to FN via contact b3 and function switches SFU1 to SFUn via changeover switch U4 hold again via their own contacts Fk to Fn via clear contact Lö2 and issue a corresponding command to the machine. At the same time, the switching device U is advanced by one step via the contacts b2 and a2, so that the next section is switched on. Both read-out counter groups run back to zero via contacts b1 and a1. The read-out counter groups can be set to zero individually or collectively using the appropriate buttons. In addition, the section can be selected as described above. As already mentioned, the control for the V-decker (Fig. 1, section SV1, SV2 ... SVn), whose electrical structure corresponds in principle to the edge decker control and which is a repetition of Fig. 5a, is connected to Fig. 5d on the right to 5d represents. The V-DQcker control is switched on by a command contactor of the edge deck control after the section controlling this contactor has expired; for example, a contact of the command contactor FL is used for this purpose.

The control of the V or inner deck usually has the task of to mark the V-neck or to cover the fassonge = right. Such a V-neck shows the pullover front part of FIG. 1.

From the above; described structure of the control device according to the invention it can be seen that this is a control for the edge decker and a control for the inner decker (V-decker). Each of these parts essentially settles from the two readout counters ZR and ZR as well as the associated switching elements, switching relays etc., to which any number of multiple switches is assigned. FIG. 6 shows, for example, the arrangement of the multiple switches ZS: -i1 to ZSRn on "a switch board 5, on which the switches by so-called printed Circuits are interconnected. Such a switch plate 5 corresponds each of the horizontal arrangement of multiple switches in the switch field 3 '. These Switch panels are commonly manufactured to be about twenty switches in length and inserted into the control device, with the remaining switching elements connected by terminal strips 53, are..We are however in a control device del construction according to the invention requires fewer sections, so the switch plates 5, for example, sawed off the designated dividing line 51 and thus to the desired Number of quadruple switching units shortened. If more sections are needed. ®o can. the Control device simply by plugging several Switch plates can be extended one behind the other in a very simple way, without that the basic unit of the control device changed in any way or must be multiplied. The switch plate 5 is only in @ a terminal strip 53 plugged in, with the individual conductor lines connected by the contact springs 54 will. This shows the particular advantage of the control device according to the invention, namely that these can easily expand or decrease according to the modular principle depending on how the intended use requires. This creates the expansion not in an expensive multiplication of each individual switching element, as is the case with the previously known devices is required, but on a few of the expensive switching elements limited basic unit remains unchanged and is only activated in the desired manner by switch plates with multiple switches added. This results in an extremely economical construction of the control device and adaptation to the respective purpose is achieved.
