Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a weft selection method and device for a loom.

2. Description of the Related Art Mechanical weft selection devices using card pegs and the like are conventionally known as weft selection devices used in looms that perform weaving using a plurality of types of weft yarns.

However, when such mechanical types are used for a long period of time, malfunctions such as weft selection errors may occur due to wear or loss of the pegs, and the card pegs are generally structured to move twice, which increases speed. Therefore, the rotation speed of the loom cannot be increased. Furthermore, when the weft yarn is not connected to a shedding device, it is difficult to match the opening pattern after the damage has been restored with the weft selection order.

In addition, in the case of a mechanical type, the cards used in so-called long repeats, which have a long number of circulation steps, are very long, and the labor for creating and managing cards cannot be reduced.

In addition, card saving devices are generally used when the same pattern is repeated during a repeat.
Since it is mechanical, there are limits to the length of cards that can be used.

Furthermore, when it is necessary to change part of the pattern due to a change in the front type, etc., it is necessary to remove the cards from the weft selection device and then change the order of the cards each time, which is a tedious task. This tendency is particularly noticeable in the case of the above-mentioned long repeat.

The object of the present invention is to overcome the above-mentioned drawbacks of conventional weft selection devices. That is, the present invention provides a control section having a central processing unit and a memory in which a weft insertion pattern consisting of an operation command program of the central processing unit and main step data and sub pattern data is stored and set, at an appropriate address of the main step. Memorize the subpattern,
In synchronization with the operation of the loom, main step data or sub-pattern data is appropriately output as a selection command signal according to the weft insertion pattern, and the selection command signal is used to select the required weft yarn, and the main step data or sub-pattern data is The gist is to display the sub-pattern data in order to confirm its contents before storing and setting the sub-pattern data in the memory.

The present invention will be described in detail below using embodiments shown in the accompanying drawings.

This embodiment is for a case where there are four types of wefts to be selected. Selection of each weft is performed by energizing any one of the solenoids Sa to Sd in response to a selection command signal. That is, the solenoid Sl! from the solenoid driver 61! Selection signal 86a corresponding to a predetermined one of L to Sd
-5(S(1), in FIG.
The control unit 1 receives respective output signals SI#S2 and synchronization signals cp from a keyboard 2, which is a data input device, a stepper 5, and a synchronization signal generator 4. The keyboard 2 is used to enter pattern data for weft selection (hereinafter referred to as weft insertion pattern data) into the memory 12 of the control unit 1, as will be described later, and to instruct pattern changes. There are keys A, P, C, E, and N having numbers and functions to be described later.

The stepper 3 advances or reverses the execution step of the weft insertion pattern stored in the memory 12 when the loom starts operating or resumes operation after returning scratches. The control unit 1 is configured to input a pulse signal by turning on each of them at a desired time. Then, by turning on each of the switches R and F once, the readout address of the weft insertion pattern data stored in the memory 12 by the central processing unit 11, that is, the execution step, is returned one address at a time.
Or you can proceed.

The synchronous signal generator 4 is composed of, for example, an absolute shaft encoder attached to the crankshaft of the loom, a comparator, a setting device, etc., and outputs one synchronous signal CP to the control unit 1 at a predetermined timing for each revolution of the loom. Enter.

The memory 12 of the control section 1 is composed of a program memory section in which a program for instructing the operation of the central processing unit 11, which will be described later, is stored and a data memory section in which weft insertion pattern data from the keyboard 2 is stored. During operation, the weft insertion pattern data stored in the data memory section are sequentially read out by commands from the central processing unit 11 when the synchronization signal CP is output from the synchronization signal generator 4. A selection command signal S3, which is a signal corresponding to the read weft insertion pattern data, is output to the solenoid drive unit 61 of the command unit 6.

The selection command unit 6 includes a solenoid driver 61 and a solenoid Sa.
% Sd, and the solenoid drive section 61 is composed of an output port and a driver for driving (energizing) the solenoids 5a to 8d. , the corresponding weft yarn is selected (a selection signal 56a-866 is output to the corresponding solenoid of Sa-8d. When a predetermined solenoid (not shown) operates for a predetermined period in response to the selection signal 86a-S6d, The weft picker is operated to select the corresponding weft.

Furthermore, the display 5 includes a main step display section 51 for displaying the address of any one of the main steps to be described later, as shown in the operation panel of FIG.
a main selection display section 52 that displays the contents (data) of the address displayed on the main selection display section 52; a substep display 53 that displays one address among the substeps of the subpattern displayed on the main selection display section 52; A sub color display section 54'' that displays the contents (data) of the address displayed on the sub step display section 53, a number when any number key (0 to 9) on the keyboard 2 is turned on, and a key when registering a sub pattern. It is composed of an entry display section 55 in which the sub pattern name NrP is displayed when N and P are pressed.

For convenience of explanation, the display specifications of these display sections 51 to 55 will be explained in parallel with the explanation of the operation.

Next, the operation of the embodiment having the above configuration will be explained using the weft selection model shown in the following table.

As a matter of course, the operation of the control section 1 to be described below is performed by storing an appropriate program in the program memory section of the memory 12 by a known method.

In the table above in the margin below, the execution step refers to the actual number of wefts inserted after the loom starts operating. The main step means the step currently being executed when the loom is operating, and the number of main steps is naturally determined by the memory capacity (number of pits) in the data memory section of the memory 12. Further, the sub-pattern can be substituted for any step in the main step, and is composed of a predetermined number of sub-steps determined by the memory capacity of the data memory section. A required set of sub-patterns is stored in the data memory section.

Furthermore, the color number represents the type of selected weft.

Therefore, the data memory section of the memory 12- is specifically composed of a main memory section that stores a required number of main steps (18 in the embodiment) and at least one set that stores a required number of substeps (4 in the embodiment). (6 sets in the embodiment) of sub-memory units. The contents of the main steps stored in the main memory section are sequentially read out in accordance with the weft insertion pattern as described later as the weft is inserted into the loom. Further, pattern names (P-0, P-1, P-2 in the embodiment) can be registered in each set of sub-memory sections, and can be called at any time and inserted into the main step at any address. Furthermore, once a sub-pattern is registered, it is possible to automatically execute its reverse sub-pattern, and it is registered as necessary (N-0 in the embodiment).
This subpattern can also be called or inserted at any time.

Next, the functions of each key will be explained. Key D is a data registration key °-, and by turning on the numeric key of the color number (1 to 4) to be selected and then turning it on, the weft pattern is inserted into the predetermined address of the previously called main step or substep. Data can be registered◆. Key P is used to register a subpattern or call a subpattern, and by turning on the appropriate number key (the number pointing to the pattern name) and then turning on key P. Any subpattern can be called. The sub-pattern is registered by specifying the sub-pattern number and then using the numeric keys and key D in the same way as for the main pattern. In addition, key C is a clear key and is used when you press a wrong number key, and the content that should be registered by turning on key C (displayed on the entry display section 55)
Clear. Key N is a backward pattern key and is used to register or call up a backward pattern of a previously registered sub-pattern. Key E is a step completion key, and indicates that the registration is completed when a pattern is registered.When registering a main pattern, the process returns to main step 1 and enters an execution standby state.When registering a subpattern, the process enters a next registration standby state. Key A is an address key, and when key A is turned on after displaying the number of steps with the numeric keys, the designated step is called, the contents are displayed on the display, and the system enters a standby state for execution at the designated step.

Next, as a preparatory step for registration, change, standby, etc., sub-patterns are first registered using the pattern model shown in the garment.

0.0 to register subpattern P-0, which is a pattern with weft numbers 1-2-3-4. P,1,D,2
．． D.5. D.4. Turn on each key D and E in sequence.

When P is turned on, the first address of subpattern P-Q is called, and 1 is displayed on the substellar two display section 53.

Then, when key 1 is pressed (0Nl = EN) IJ-display section 55
1 is displayed, and after confirming this, if key D is turned on, color number 1 is registered in the first address of subpattern po, and at the same time, the next step is displayed in substep display section 55. 2 is displayed. Similarly, key 2. D.

By turning on 3*D+4*D*E, color numbers 1-2-5-4 are registered in subpattern po. Also, the retrograde pattern of subpattern P-0 (4
-3-2-1) is automatically registered in the data memory section of the memory 12 as N-0 by turning on keys N and 0°D.

After registering sub-patterns P-0 and N-0 as described above, main steps 1 to 18 are set and registered as follows. First, key 1. By turning on A, the main step address 111 is called. At this time, 1 is displayed on the main step display section 51.

Next, when key 1 is turned on, 1 is displayed on entry display section 55. After confirming this, if you turn on key D, 1
Color number 1 is registered in the address! : At the same time, 2, which is the next step, is displayed on the main step display section 51, and address 2 becomes the registered town. In this way, main step addresses 1 to 4 are registered according to the initial registration in the table.

Next, in a state where the registration up to main step No. 4 is completed and 5 is displayed on the main step display section 51, in order to register the sub pattern P-Q in the main step 5, press the keys P, O, D can be turned ON sequentially.

When the registration of main step No. 5 is completed, 6 is displayed on the main step display section 51, and 6 is displayed in the same way.
Registration of addresses up to the 18th address can be performed by turning on each key in sequence as shown in the initial registration column of the table. In this way, main steps 1~
The weft insertion data up to address 18 is stored in the data memory section of the memory 12. By turning on the key accent at 11, 1 is displayed on the main step display section 51, and the control section 1 is Preparations for issuing the weft selection command signal S3 repeatedly according to the data registered sequentially from the first address to the 18th address of the cylinder are completed and the machine enters a standby state. At this time, on the display 5, 1 is displayed in the main step display section 51 and 1 is displayed in the main select display section.

After completing the above steps, the loom starts operating. When the loom starts, the weft with the color number registered at the address shown on the main step display section 51 of the operation panel will be inserted next time. It is a weft type. Therefore switch R
, F can be turned on as appropriate to change the address shown on the main step display section 51 and start the weft insertion pattern from a desired address. It is also possible to change the address of the main step executed by key operations on the keyboard 2, as will be described later, without using switches R and F.

When the loom is started with 1 being displayed on the main step display section 51, the synchronous signal CP is output from the synchronous signal generator 4 at a predetermined timing after starting. At this time, the control section 1 outputs a selection command signal S3 having a value corresponding to the weft insertion data at the first address of the main step stored in the data memory section of the memory 12 to the solenoid driver 61.

The color number at the first address of the main step is 1, so the corresponding weft is selected and inserted at the timing of weft insertion. Similarly, the data of main steps Nos. 2 to 4 are sequentially read out as the loom rotates, and the corresponding weft yarns are selected and inserted.

When the operation of the loom progresses and the main step display section 51 reaches 5, the main select display section 52 shows p-o.
, 1 for the sub-step display section 53, and 1 for the sub-color display section 5.
4 is displayed, and a selection command signal S6 corresponding to color number 1 is output to the solenoid driver 61.

In this way, the data of main step Nos. 6 to 18 are sequentially read out each time the loom rotates, and the corresponding weft yarns are selected and inserted. Then, main steps 1-1
When the reading car up to address 8 is completed, that is, after the loom starts and 50 wefts are selected and inserted, the E signal is stored in memory, so the main step returns to address 1 and reads the 51st weft. Subsequent selection of weft yarns is again performed based on the weft insertion data registered at main step addresses 1 to 18.

When the loom stops due to a trouble such as a weft insertion error occurring during operation of the loom, and the loom is restarted after the trouble is removed, the following changes are made to the execution steps shown to the ex-husband. This will be explained below.

■ indicates execution step address 9, i.e. reading of the weft turn data up to main step address 6 is completed, and after the weft of color number 1 is finished, the loom power is stopped and scratches are restored to eliminate trouble. This is a case where 1 is necessary to return to execution step 9 due to a meeting etc. At this time, 7 is displayed on the main step display section 51 and 1 is displayed on the main select display section 52. .

In this state, (1) If key 6 is turned ON, 6 will be displayed on the entry display section 55, and then by turning key A ON, the read address will be returned to main step No. 6 address, that is, execution step 9. I can do it. Further, as in (11), in this case, the step is returned by one step, so the switch R of the stepper 3 may be turned ON only once.

In the case of ■, as in ■, (1) First, key in 5+A to return the read address to the 5th address of the main step, then key in 2・Fl or F + F, or
(++)4. By keying in R, R* R, or Rt R, the read address can be returned to the seventh execution step address.

Similarly for ■ and ■, (+)7°A(
li)4. For R or R, R, RIR, ■ (
+)2. R or R, R (II)9. By keying in A and F, the read address can be changed to a desired position.

The four examples ① to ② illustrate changes from a main step to a main step, from a main step to a substep, from a substep to a main step, and from a substep to a main step.

Next, changing the weft insertion pattern when changing the loom will be explained using examples of ■ to ■ in the table.

■ is a case where you want to delete the 3rd address of the main step in the weft insertion pattern.If you first key in 3, 3 will be displayed on the entry display section 55, and then by keying in A, the 3rd main step address will be called. , 3 and 4 are displayed on the main step display section 51 and main selection display section 52, respectively. In this state, if you key in 0, and then key in D with 0 displayed on the entry display section 55, the weft insertion data at address 3 of the main step will be erased from the memory 12, and the weft insertion pattern will change to the main step. It is determined by the color numbers registered in 1.2.4 to 18.

■ is the sub-pattern registered in main step 5.
This is a case where it is desired to change from color o to a sub-pattern with color number 2-3. First, in preparation, a sub-pattern with color number 2-3 is registered and stored in the memory 2 as sub-pattern name P-1 by operating the same keys as when P-0 was registered. Next, by keying in 5°A, main step number 5 is called up, and at this time, 5 is displayed on the main step display section 51. And main step 5
Since the sub-pattern p=o has already been registered in the address, P-◯ is displayed on the main selection display section 52.

In this state, if you key in P and 1, the entry display section 5
P-1 will be displayed at 5, and if you then key in D, sub pattern P-1 will be registered at main step address 5.
The contents of the main step address 5 are changed from subpattern po to P-1.

■ is the weft entry data of main step No. 14 with color number 1.
This is a case where it is necessary to change from 2 to 2. First, if you key in 1°4, 14 will be displayed on the entry display, then press A.
By keying in, the 14th main step address is called up, and 14.1 is displayed on the main step display section 51 and main select display section 52, respectively. In this state, if the user presses the key 2 to display 2 on the entry display section 55, then the color number of the 14th main step address is changed from 1 to 2, and the change is completed.

■ is the weft entry data of main step No. 16 with color number 6.
In this case, it is desired to increase the number of steps from the color number + 4.5 to 5 steps. First 2. P.

1, DI4. D.5. Press D and E in sequence to register a new sub-pattern P-2. Next, the IP keyed in 1.6°A and called main step number 16.
2. By keying in D in sequence, registration of sub pattern P-2 at main step address 16 is completed, and main step address 16 is changed to 3 steps from color number 6 to ++4.5.

Furthermore, the case where it is desired to read the weft insertion data from an arbitrary address of the main step as necessary and start the weft insertion pattern from that address will be explained by taking the case □ in the table as an example. ■
For example, if you want to start from main step No. 10, if you key in 1, 0, and A in sequence, main step No. 10 will be called up and 10 will be displayed on the main step display section 51, so in this state All you have to do is start the loom.

In the embodiments described above, the display device is digitally displayed on the operation panel, but in other embodiments, the respective displays may be displayed at appropriate positions on the picture frame of the CRT. Further, the setting and registration of the weft insertion pattern using various keys may also be carried out using a light pen or the like on a CRT.

As described above, according to the present invention, unlike the conventional mechanical type using carded bets, there is no missing or worn out bet etc., so there is no malfunction, and the correct predetermined weft can always be selected. In addition, since there is no need to plant beds, labor can be saved, and the loom can be operated at higher speeds, and the number of stops due to malfunctions is reduced, so the operating rate can be increased. Furthermore, since the weft insertion pattern is stored in the memory, the labor required for switching types, etc. can be greatly reduced. In particular, if there are repeats of the same pattern (or repeats of the opposite pattern) in the weft insertion pattern, you can register that pattern as a sub-pattern, which greatly reduces the setting power of the weft insertion pattern. Reduced.

As an example of registering a weft insertion pattern, in the embodiment, it was explained that registration is performed only by key operation.
When weaving the same type of material on multiple looms, first register and store the weft insertion pattern in the memory of the control unit of one loom, and then control it in an appropriate storage device such as tape or RAM with power backup. The weft insertion pattern stored in the memory of the loom may be stored, and the weft insertion pattern may be recorded and registered in the memory of the control section of another loom via a tape reader or the like.

Furthermore, when setting the weft insertion data using the display, the setting contents can be confirmed on the IJ-display section, thereby making it possible to prevent erroneous data registration.
