Abstract

The system contains an input block (1), a ferrite memory (2) to which a pulse generator (5) is connected via a counter (4), and actuating members (10) which are controlled by a change-over switch (8) from the address register (9) and photoelectric transmitter (11). Between the ferrite memory (2) an the change-over switches (8) a register memory (3) is connected in order to control each actuating member (10). As a result, it is not necessary for the machines of a group to work synchronously and the individual machine does not need any program carrier and reader. <IMAGE>

Description

(54) APPARATUS FOR CONTROLLING A PLURALITY OF LOOMS OR KNITTING MACHINES (71) We, CENTRALEN SAVET PRI NAUCHNO-TECHNICHESKI SAYUSI, of 108, Rakovski Street, Sofia, Bulgaria, a Scientific Technical Union organised under the Laws of Bulgaria, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to apparatus for controlling a plurality of looms or knitting machines in accordance with a common stored programme.
A problem in the control of a plurality of machines in accordance with a common programme is the avoidance without great complexity of equipment of the need to have the machines running in close synchronism with one another. This invention seeks to solve this problem and to provide an apparatus for-the control of a plurality of machines in accordance with a common stored programme without the need for the machines to operate in such close synchronism.
According to one aspect of the present invention there is provided apparatus for controlling a plurality of looms or knitting machines in accordance with a common programme, comprising an operating store for storing said programme and a plurality of machine controlling units, a respective one for each of the looms or knitting machines to be controlled and each comprising electronic switch means for controlling the performing means of the respective loom or knitting machine to be operated in a line of operation of the machine, a line address register for producing a signal to identify the line of operation of the machine and a line completion indicator to provide a signal for the line address register to indicate the completion of a line of operation; the arrangement being such that during operation of the apparatus programme information is supplied from the operating store to all of the control units but each control unit selects from the supplied programme information only that programme information which corresponds to the line address identified by its associated line address register and uses that information in the control of the performing means of its respective machine.
According to a second aspect of the present invention there is provided apparatus for controlling a plurality of looms or knitting machines in accordance with a common programme, comprising a ferrite store for storing the complete said programme, an operation store for also storing the complete said programme, read-out means for reading the programme out of the ferrite store and into the operating store at the beginning of operation of the apparatus or after unintentional erasure of the programme from the operating store, and a plurality of machine control units, a respective one for each of the looms or knitting machines to be controlled and each comprising electronic switch means for controlling performing means of the respective loom or knitting machine to be operated in a line of operation of the machine, a line address register for producing a signal to identify the line of operation of the machine and a line completion indicator to provide a signal for the line address register to indicate the completion of a line of operation; the arrangement being such that during operation of the apparatus programme information is supplied from the operating store to all of the control units but each control unit selects from the supplied programme information only that programme information which corresponds to the line address identified by its associated line address register and uses that information in the control of the performing means.
The operating store is preferably in the form of a matrix of trigger-type storage elements.
For a better understanding of the present invention reference will now be made to the accompanying drawing which shows in block diagrammatic form one embodiment of the invention. As is usual, the arrows on the connections between blocks in the diagram indicate the directions of flow of signals between the blocks.
The apparatus for the control of a plurality of looms or knitting machines shown in Figure 1 has an input and storage section which is common to all of the machines and which comprises an input block 1, a ferrite store 2 with an associated counter 4 and pulse generator 5, and an operating store 3 which may be a trigger-type matrix store.
The apparatus has in addition for each machine a respective unit 7 coupled to the outputs of the store 3 through coding busbars 6 and each of which units 7 is made up of an electronic switch means 8, a line address register 9, a set 10 of machine performing means and a photocell line completion indicator 11.
To set up the apparatus, the pattern of the knitwear, jacquard or other fabric to be produced is by means of the input block 1 entered as a coded programme into the ferrite store 2. For example, the pattern may be applied first of all to squared paper readable by the block 1. Throughout the operation the programme remains stored in ferrite store 2. The programme is also read into and stored in the operating store 3 from store 2 using the counter 4 and the pulse generator 5. This takes place at the start of the operation or automatically after any emergency cut-off which has resulted in the erasure of the information from the store 3.
The programme signals from the outputs of the store 3 are fed over the busbars 6 to the electron switch means 8 of the units 7 but each switch means 8 selects and only accepts that part of the programme information which corresponds to the line address indicated by its associated line register 9.
The line register 9 for each unit 7 starts by giving the code address of the first line of the pattern to be reproduced by its loom or knitting machine and after completion of that line provides the code address for the next line to its switch means 8. A signal to step forward the line address of the register 9, after a line of operation is completed, is provided by the photocell line completion indicator 11 of the unit 7 which photocell 11 may be attached to the crank shaft or other appropriate operating member of the machine or loom. In this way each unit 7 extracts the information it needs from the output signals of the store 3 in dependence upon the particular line of operation of its own machine and it is not necessary that the different machines run in synchronism.
WHAT WE CLAIM IS: 1. Apparatus for controlling a plurality of looms or knitting machines in accordance with a common programme, comprising an operating store for storing said programme and a plurality of machine controlling units, a respective one for each of the looms or knitting machines to be controlled and each comprising electronic switch means for controlling performing means of the respective loom or knitting machine to be operated in a line of operation of the machine, a line address register for producing a signal to identify the line of operation of the machine and a line completion indicator to provide a signal for the line address register to indicate the completion of a line of operation; the arrangement being such that during operation of the apparatus programme information is supplied from the operating store to all of the control units but each control unit selects from the supplied programme information only that programme information which corresponds to the line address identified by its associated line address register and uses that information in the control of the performing means of its respective machine.
2. Apparatus for controlling a plurality of looms or knitting machines in accordance with a common programme, comprising a ferrite store for storing the complete said programme, an operating store for also storing the complete said programme, read-out means for reading the programme out of the ferrite store and into the electronic store at the beginning of operation of the apparatus or after unintentional erasure of the programme from the operating store, and a plurality of machine control units, a respective one for each of the looms or knitting machines to be controlled and each comprising electronic switch means for controlling performing means of the respective loom or knitting machine to be operated in a line of operation of the machine, a line address register for producing a signal to identify the line of operation of the machine and a line completion indicator to provide a signal for the line address register to indicate the completion of a line of operation; the arrangement being such that during operation of the apparatus programme information is supplied from the operating store to all of the control units but each control unit selects from the supplied programme information only that programme information which corresponds to the line address identified by its associated line address register and uses that information in the control of the performing means of its respective machine.

For example, the pattern may be applied first of all to squared paper readable by the block 1. Throughout the operation the programme remains stored in ferrite store 2. The programme is also read into and stored in the operating store 3 from store 2 using the counter 4 and the pulse generator 5. This takes place at the start of the operation or automatically after any emergency cut-off which has resulted in the erasure of the information from the store 3. The programme signals from the outputs of the store 3 are fed over the busbars 6 to the electron switch means 8 of the units 7 but each switch means 8 selects and only accepts that part of the programme information which corresponds to the line address indicated by its associated line register 9.
