Flat knitting machine with electronic control Field of application of the invention:

The invention relates to a flat knitting machine with electronic control, which contains programmable read-only memories in the form of PROMs and freely accessible memories in the form of RAMs as well as components for inputting the data for the operation of the machine.

C characteristic of the known technical solutions;

From DE-OS 2 301 847, such a flat knitting machine with electronic control has become known. The data is entered there via a magnetic tape memory or by hand. Fixed-value memories are provided for parts of the permanent operating program, while all other data for each setting of the machine must be entered into a freely accessible memory RAM. This leads to increased effort and increased error probability.

By the journal "Knitting and knitting technology", October 1977, pages 496 to 500, an NC-controlled flat knitting machine has become known in all

13JIIL1981 * 946741

233783 7

Machine functions can be controlled by means of moving perforated strips. This is the knitting program set, any repetitions are not possible.

By DE-OS 2,120,892 finally, a flat knitting machine is known, the read-only memory for certain basic knitting types and their Nadeleinteilung contains. Freely accessible memory RAM for the pattern-specific data is not available there.

In flat knitting machines with electronic control, the input of data for the operation of the flat knitting machine is very complicated and time consuming, so that this input so far could only be successfully performed by specially trained specialists.

Object of the invention:

The aim of the invention is to provide a flat knitting machine of the type described above, which allows the data input to the flat knitting machine with only trained in the field of data input forces with minimal time and minimal probability of error in data entry.

Explanation of the essence of the invention;

This object is achieved according to the invention in that the controller comprises an internal interface unit, a programmable read-only memory unit, a microprocessor and a data storage unit with random access, which are interconnected via a common address, data and control bus that ir the read-only memory unit and in the Data storage unit separate memory for the data of five subgroups

233783 7

Programmable read only memories are provided for all Oaten the subgroup Knitting Scheme and a part of the Oaten of the subgroup function number list in the read-only memory unit for the knitting of standard pattern image cartridge, Nadeleinteilung, knitting scheme, function number list and scheme.

Conveniently, a device including a keyboard, display, counter and switch, coupled to the internal interface unit for inputting the standard pattern subgroup knitting scheme and the required part of the subgroup function number list is incorporated directly into the read only memories of the read only memory unit in the machine.

According to a further feature of the invention, a data carrier device with associated data carrier for inputting the data for the standard pattern of the subgroup knitting scheme and the required part of the subgroup function number list can be connected via a prepared external data carrier in the read only memory of the read only memory unit to the internal interface unit.

In the first-mentioned expedient embodiment, it is advantageous to provide a function key connected to the internal interface unit for retrieving the data for standard patterns on the machine.

Suitably, the arrangement is made so that a data carrier device with associated data carrier for storing all data for the operation of the flat knitting machine for each subgroup individually or combinations thereof is connected to external media / magnetic tape cassettes, for example, from the memories of the read only memory unit and the data storage unit to the internal interface unit ,

2337 8 3 7

Also, it is advantageously possible to switch the counters of the device connected to the interface unit to input commands for selection of one or more knitting needle groups without changing the input and stored data.

The switches of the components connected to the interface unit are suitably switched to input commands for suppressing one or more rows of knitting without changing the input and stored data.

Finally, it is still advantageous to provide a keyboard or a switch on the machine, which is connected to directly input the information about fineness of the flat knitting machine in the memory of the data storage unit with the internal interface.

The aforementioned sub-group Knitting Scheme contains all the data that are required for the function of the machine in a knitting row, while the additional data from the sub-group function number list, which are stored in the read-only memory, the order of such functions in the knitting sequence. Thus all machine-specific data for the knitting of standard patterns are permanently stored in the electronic control of the flat knitting machine, while only the pattern-specific data from the sub-groups image cartridge, Nadeleinteilung, Scheme process and the remaining part of the subgroup function number list processed by the knitter and entered into the flat knitting machine .

The standard patterns whose data are hard-coded into the machine are colored and tagged ocquard patterns such as two-color jacquard pattern, three-color jacquard pattern, four-color jacquard pattern, half-tube pattern and cable pattern.

233783 7

Oils electronic control 1st, as already indicated, constructed and switched so that the data for the standard pattern of the subgroup knitting scheme and the required part of the subgroup function number list can be entered directly to the machine in the read-only memory. Alternatively, these data can be stored via a preparatory

teten external disk, preferably a magnetic ''

tape is to be entered in the fixed memory.

The advantage of data input is that all data for the operation of the flat knitting machine for each subgroup individually or in combination thereof on external data carriers, such as magnetic tape cassettes, from the memories of the electronic control can be stored. The external data carriers can then be used in the stored sequence or in a new combination for entering the archived sample and operating data or new patterns to be created. It is important that all necessary for the operation of the flat knitting machine data are stored and archived.

In order to have virtually unlimited possibilities for compiling new patterns from the stored and archived data, data parts of the subgroups are stored to a minimum of the data for one needle on the external data carriers.

By means of presettable counters provided on the machine, the commands for selecting one or more groups of knitting needles can be inputted without changing the data entered and stored. The data in the counters have priority over the data of the subgroups, so that, for example, the width of the pinspace is independent of Knitting program change, whereby optionally a Breitenrapport is automatically interrupted. Thus, a knit width change without intervention in the knitting program can be realized.

233 783 7

On the machine switches can be provided, can be provided via the commands for suppression of one or more knitting rows without changing the entered and stored Oaten * With such a length limitation, the knit length superordinate to the knitting program, in particular the sub-group scheme sequence can be shortened. The pattern can be canceled at any length, provided that the thread guide and the offset at new start in the then required basic position. This data entry into the machine also takes place outside the five program sections.

The information about the fineness of the flat knitting machine can be entered directly into the electronic control via the aforementioned keyboard or a corresponding switch. | Thus, the subsequent input of data for the operation j of the flat knitting machine can be automatically adapted to the respective fineness.

Finally, the flat knitting machine according to the invention can be developed such that a keyboard or a switch is provided on the machine, via which the information on fineness of the flat knitting machine can be entered directly into the electronic control. Thus, the subsequent input of data for the operation of the flat knitting machine can be automatically adapted to the respective fineness.

Ausführungsbeisp iel:

The invention is explained in more detail below with reference to exemplary embodiments. The accompanying drawing shows a block diagram of the electronic control.

In the block diagram, the component is installed in the frame of the flat knitting machine, which has a keyboard,

contains a display, a counter and a switch.

The interface unit 2 is an internal interface module constructed as an IC module, and the read-only memory 3 is a programmable read-only memory PROM constructed as an IC module. The microprocessor 4 is a microprocessor module constructed as an IC module. The data storage unit 5 is a random access data memory RAM constructed as an IC module.

The component 1 and the interface unit 2 are operatively connected to each other in both directions.

The interface unit 2, the read-only memory unit 3, the microprocessor 4 and the data storage unit 5 operate on the common control bus 8, which is strictly an address, data and control bus and receive via this bus 8 information or signals.

With the interface unit 2 is also a data carrier device 6 in mutual operative connection. The data carrier 7 receives its recordings from the data carrier device 6 and delivers its recordings via the data carrier device 6 to the interface unit 2.

For entering data for the operation of a flat knitting machine with electronic control is advantageously a complete knitting program on a magnetic tape, so the disk 7. This magnetic tape is then recorded using a tape device, the disk device 6 in the electronic control of the machine. The electronic control of the flat knitting machine contains read-only memory, for example in the form of PROMs and freely accessible memory, for example in the form of RAMS. In such a controller

The data for the operation of the machine can be supplemented by importing one or more subgroups or parts of subgroups of the data, thereby obtaining a new overall program.

The compilation of data is based on specially prepared forms, each Teilgruppa of data being assigned a form. The usual program execution can then take place with the aid of true magnetic tapes, for example two magnetic tapes, of which one tape contains, for example, three subgroups of data and the other tape contains two subgroups of data.

The entire data for the operation of the flat knitting machine are divided into a total of five sub-groups in order to make the simplest possible and error-free data entry with the least possible amount of work by rarely the input operator.

The five subgroups of data are a first subgroup image cartridge, a © second subgroup. Needle Division N, a third subgroup Knitting Scheme, a fourth subgroup Function Number List and a fifth subgroup Scheme Sequence.

The first sub-group of image cartridges of data corresponds to a technical cartridge for knitting, stitch transfer and stitch transfer for the front needle bed in, for example, the creation of a braid pattern.

The second sub-group Needle data division comprises the horizontal sequence of the knitting process · It is possible to enter a normal input with automatic repetition across the entire machine width. More than eight knitted ribbons or needle divisions must be entered via single input

233783 7

be determined. In total, up to 64 needle divisions are possible. Furthermore, up to 64 selector switches with a maximum value of 255 repetitions of data and data groups are provided on the machine.

The data for both the image cartridge subgroup and the subgroup needle classification are sample-specific data.

The third subgroup Knitting Scheme refers to the series setting for standard patterns, i. the data about what should happen in a row, such as putting on, shifting, stitching, catching, off, threading. This sub-group Knitting Scheme contains machine-specific data for knitting standard patterns of waistband and wrap-around dacquard patterns such as two-color jacquard patterns, three-color jacquard patterns, four-color jacquard patterns, half-tube patterns, and braid patterns. The data of this subgroup Knitting Scheme are entered in the fixed memory of the electronic control of the flat knitting machine and can be retrieved from there via a function key or stored for archiving to external media.

The fourth subgroup of data is the subgroup Function Number List. This subgroup contains the data on the use of the function series defined in the subgroup Knitting Scheme as well as on the use of function series from the pattern-specific data. The recurring function series can be called up as required from the machine-specific subgroup Knitting Scheme. The subgroup Knitting Scheme additionally relevant data of the subgroup Functionalnamernliste are also taken over into the fixed link memories of the machine. The other pattern-specific data from the subgroup Function Number List are entered into the electronic control of the machine during each machine preparation. The

Subgroup function number list concerns u.a. the repeat of the piece of knitting.

The fifth subset of data is the subgroup schema flow. This subset contains pattern specific data for the vertical process of knitting. The data are respectively inputted by the operator in the preparation of the knitting machine i.i the electronic control.

As already mentioned, the data for standard screens may be colored and umber jacquard patterns, e.g. Semi-tubular patterns, cable patterns or two-, three- and four-color jacquard patterns, are summarized as constantly recurring data and defined in the sub-group Knitting Pattern Z of the data. This is possible up to the scheme line maximum 320, because the knitting process as such for the mentioned standard pattern is always uniform. The data of the subgroup Knitting Scheme are stored together with the additionally required for the standard pattern data of the subgroup function number list in the control of the flat knitting machine and there are available for retrieval or for retrieval for archiving purposes. The data of the other subgroups must be redefined and entered into the machine. For the entire knitting process all data of the five subgroups will be used together. Although different image cartridges show different image patterns, but have knitting technology the same processes.

For the pattern input, it is possible to give them either with the help of an input device to an external disk in the form of a Magnetbandkessette and pass from there to the controller, or it can be entered even without magnetic tape cassette directly from the bathroom console in the controller. The latter input type has the

- 11 -

233783 7

Advantage that the input device and the magnetic tape device are not necessarily needed, for example, if they are not available for repair or use on another machine. Further, corrections in the machine via the control panel and a subsequent tape rewriting by Oberspielen a perfect magnetic tape.

With the subdivision of the data required for the operation of the flat knitting machine in the subgroups image cartridge, Nadeleinteilung, knitting scheme, function number list and schema flow and storage of data for the knitting of standard patterns from the complete sub-group knitting scheme and the required part of the subgroup function number list in read-only memory of the electronic control of the flat knitting machine not only the simplest possible data entry into the machine is achieved, but it is also possible to archive the data for complete knitting programs quickly and cheaply. This archiving can take the form of retrieving and storing the complete data on one or more external data carriers, preferably magnetic tapes. In turn, the external data carriers containing all the data for a particular knitting operation of one or more knit pieces may in turn be used to input the data into the machine by semi-skilled assistants. In addition, it is possible to create data prints from the data archived on the external data carriers, which give the knitter a direct overview of the stored data in knitting machine-specific form.

In addition to a full archiving as described above, a partial archiving is possible and provided, i. that the data of each of the five subgroups can be retrieved and archived in groups. Of course

It is also possible and intended to retrieve and archive arbitrary parts of the data of a subgroup to a minimum of one needle. Also, the data can be taken in subgroups of different machines and combined to a total data archiving. By combining individual existing subgroups of data or data subgroups, fast and inexpensive creation of new overall data for the operation of the flat knitting machine with a different combination of knits and patterns is possible. The duplication of the archived data on other external data carriers, in particular in the form of magnetic tape cassettes, prepares no difficulties with the described method.

Another way to simplify the input of data for the operation of the flat knitting machine is to make a determination of needle room widths by superordinate commands for a selection of one or more groups of knitting needles. The input of these commands to the machine is via presettable counters on the machine without changing the complete data entered and stored in the electronic control according to the subgroups of data. The determination of the Nadelraumbreiten is thus independent of the knitting program, the determination of the needle room widths is superordinate to the knitting program and optionally interrupts a wide rapport. However, the data corresponding to the instructions for determining the needle room widths can be stored and archived, if necessary, together with all the data about the knitting program on external data carriers and archived. With this type of superordinated specification of pinhole widths, the needle space used for knitting can be chosen arbitrarily. For example, the fineness corresponds

- 13 -

- »- 233783 7

E12 of the needle beds of a total needle count of 972 per needle bed. Within this total needle count, if the working width is to be, for example, 800 needles, the needle space can be chosen arbitrarily, e.g. from needle 91 to 890.

Further, it is possible to knit up to eight separate knit parts of equal or different width, e.g. for scarves and the like, with the help of the definition of the needle room widths with unaltered knitting program prepare or enter into the machine. The superordinate determination of the needle room width allows a knitting size change without intervention in the knitting program.

A similar development of the described method is to enter commands for suppressing one or more rows of knitting without changing the input and stored data via switches or the like. Again, these commands are again superior to the knitting program. With such a length limitation, the length of the knitted fabric can be shortened contrary to the data specified in the sub-set of schema sequence. Assuming that the thread guides and the offset are in the required home position when the knitting is restarted, the pattern can be broken at any length.

Finally, information about the fineness of the flat knitting machine is entered via a keyboard by means of a code or via a switch directly into the electronic control. This is an automatic preparation of the electronic control of the flat knitting machine for the later data input for automatically processing the information on the fineness of the data input.
