This invention relates to a pattern setting device for an electronic knitting machine, and in particular, when the power connected to the knitting machine is turned on, the operation of the knitting machine is stopped and the storage state of the various constants can be checked.

[Prior Art] In a conventional pattern setting device for a knitting machine of this type,
Various constants for pattern creation, such as the number of stitches of the knitting machine, pattern output timing, etc., are set and memorized to suit the knitting machines to be combined, and are used when knitting patterns. While connected to the knitting machine, the knitting machine supplies various constants stored in the memory to the knitting machine and performs the required pattern knitting.

[Problems that the invention aims to solve] However, in general, the above constants are set for each knitting machine by the knitting machine manufacturer or end user, and stored in advance in memory such as programmable read-only memory (P-ROM). However, in order to check and reconfirm the stored contents of the various constants that have been set, it is necessary to remove the P-ROM, etc. that stores the various constants from the device, insert them into a memory reader, and read them. Therefore, there was a problem that inspection of various constants of the knitting machine for patterning once set was extremely complicated.

The purpose of this invention is to eliminate the above-mentioned drawbacks of the conventional methods, and to make it easy to check the previous knitting conditions when operating the knitting machine, if it has been a long time since the last operation, or if there is a change of operator. The various constants for patterning of the knitting machine that have been set and memorized in advance so that it can be

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a pattern setting device for a knitting machine in which a memory means for storing various constants for pattern setting of the knitting machine and a group of operation keys are arranged. a keyboard and a display means, the constants stored in the memory means are displayed on the display only under the condition that a predetermined operation key of the keyboard is pressed down when the power is turned on. It is characterized by having a control means for activating a display and diagnosis program.

[Function] Therefore, the present invention is connected to a knitting machine and inhibits the operation of the knitting machine in response to the detection of a key operation of a specific push button when the power is turned on immediately before starting pattern knitting. In a safe state where the interlock is applied to the knitting machine and the knitting operation is stopped, check the constants by reading the various constants for pattern making that have been stored in advance in the built-in storage device and making sure that they can be done when starting the diagnostic program. After confirming that there are no errors, you can begin the compilation work.

[Example] The present invention will be described in detail below with reference to the drawings.

First, an example of a schematic circuit configuration of a pattern setting device for a knitting machine according to the present invention is shown in FIG.

A central processing unit (CPU) 1 controls each component within the device according to a control system program stored in a first read-only memory (ROM) 8 in advance. The second read-only memory (ROM) 9 is a programmable read-only memory (P-ROM) that stores various constants for patterning of the knitting machine to be connected. A first random access memory (RAM) 10 is used as a work area for temporarily storing various data necessary for various operations of the patterning device. A second random access memory (RAM) 11 is used to store pattern data to be knitted by the knitting machine, and is backed up by a battery 12 to protect the memory contents from being erased in the event of a power outage. be.

The display 2 is used to display the operating status and internal information of the patterning device, and for example, in this embodiment, a dot matrix display with 32 characters of 16 characters x 2 lines is used. Keyboard 3 is
A group of push buttons and switches for inputting commands to the patterning device are arranged. A cassette/magnetic tape (MT) device 4 loads pattern information to the pattern setting device. Input section 5
and output section 6 is an input/output interface for controlling the drive section of the knitting machine. Furthermore, the knitting machine interlock output unit 7 outputs an interlock signal to stop the operation of the knitting machine when checking various knitting machine constants for pattern making stored in the ROM 9 prior to knitting the pattern. It is generated and output.

Next, FIG. 2 shows an example of the layout and configuration of the operation panel of the present invention patterning device shown in FIG. 1. In the operation panel with the configuration shown in this figure, the cassette shown in Fig.
The MT device 4 is placed at the top to form a cassette MT panel 21, the display 2 in FIG. 1 is placed at the middle to form a display panel 22, and the keyboard 3 in FIG. 1 is placed at the bottom to form a key group 23A. ~23D.

Next, the flowchart in FIG. 3 shows an example of the operation process when the power is turned on for the pattern forming apparatus of the present invention shown in FIGS. 1 and 2. First, in step S1 immediately after the power is turned on, system initialization work such as initialization of the work area of the arithmetic processing RAM 10 and initialization of registers is performed.

Next, in step S2, it is determined whether or not the operation key 23A on the operation panel shown in FIG. 2 is pressed, and if the key 23A is not pressed,
Shift to the normal knitting work of the knitting machine in step S3,
Perform pattern knitting.

On the other hand, when key 23A is pressed,
Proceeding to step S4, an interlock command for prohibiting the knitting operation to the knitting machine is outputted from the knitting machine interlock output section 7, and then the process proceeds to step S5, in which the pattern outputting internal information stored in the ROM 9 in the device is output. It performs display processing such as reading out various constants and displaying the read-out internal constants on the display 2, and performs diagnostic work.

In this embodiment, the internal constant display processing is as follows:
As described above, each time the key 23A in FIG. 2 is pressed, the constants stored in the ROM 9 are changed and displayed on the display 2 of the display panel 22. Fourth
An example is shown in the figure. That is, the first key 23
By pressing A, for example, the number of stitches among various constants is displayed (S11), and then by pressing the key 23A again (S12), the contents of another constant 1 are displayed (S13),
Then, when the key 23A is pressed again (S14), another constant 2 is displayed, and in the same manner, various constants are sequentially displayed. Also, after that, key 23 in FIG.
When you press B, a diagnostic program that diagnoses the condition of each part of the patterning device and knitting machine is started, and the fourth
