Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for an industrial sewing machine, and particularly to an 11-style sewing device that has IT functionality for sewing a wide range of patterns.

Conventionally, the pattern stitching device constituting the control device of an industrial sewing machine has been limited to a configuration that can only produce a number of pattern stitches. For this reason, the selection of sewing patterns in pattern sewing is difficult to select, resulting in a lack of versatility.

SUMMARY OF THE INVENTION An object of the present invention is to provide a pattern sewing device that does not selectively sew specific and limited a-cross stitches, but can set an arbitrary sewing wedge.

The present invention allows the number of sewing steps of a sewing pattern to be set, as well as the number of stitches and sewing speed in the sewing step, the sewing start method (forward stitching or reverse stitching) and processing (presence or absence of reverse stitching at the beginning) of the sewing step. Processing during the process (presence or absence of reverse stitching), sewing end point of the process 8! (Whether or not there is light cutting, thread removal, and presser foot lifting,
This makes it possible to set the upper stop hand or the lower stop hand.

In history, it is a friend that allows you to sew a set sewing pattern up to 4 times.

The rotation of the sewing machine needle is determined by the speed detector TG, and the upper and lower positions of the sewing machine needle are determined by the position detector PS.
It is controlled by the @ symbol.

Various kinds of sewing can be performed using the control device as described above. A pattern sewing device sets the sewing pattern for this sewing.

The appearance of the pattern sewing device according to the present invention will be explained in a second detail. In the figure, 1 is a pattern sewing device, 2a to 2, fti, a numeric display, 3 is a clothes ring that indicates a full set, 4 is an indicator lamp that indicates a set error, and 5a to 5C are a numeric display 2.
d to 2f, pushbutton switches 63 to 611] are pushbutton switches to instruct each corresponding action, and 7M to 7mFi are pushbutton switches 63 to 6m to instruct each corresponding action. 8a and 8b are rocker switches that set the start and end reverse stitches, 9 is a button switch that holds the contents of ``S'' after the setting of one step is completed, and 1O is the setting of one step. Button switch for reading the contents,
11 is a bushing switch for reading out the set pattern.

Now, we will explain the lifting platform used to construct the 3-ellipse Matome sewing machine as shown in Fig. 2 using the Bokumo sewing device 1. First, the sewing pattern (a) is set as follows. Sewing pattern #l! When no settings are made, the number indicators 23 to 2c for the pattern plate, setting metalwork @ number, and process number are rlJ and ro, respectively.
ll, rolJ. In this state, the number of stitches is A,
The display on the H numeric display 2f is A=4. Turn on the bushing switch 5C for the number of times so that B=4. Next, turn the rocker switch 8a to the "r B Z-ya" side. Switch 5m to display the number of stitches on the clothing accessory 2d.
-Turn on the number of required trade (b) and make it 15. Now, A=4.8=4. This means that the number of stitches is e=15. The display on the set speed numeric display 2e is set to the speed at which C=15 is manufactured by thI. For example, if it is 2200r, p, m, the number display 2c is set to ``22'' by turning on the bushing switch 5b the required number of times. The beginning and end #) of the sewing patterns in Fig. 3 (a) and (b) are th! Because it affects the appearance of the table? It is predetermined in the bI4 raising unit CB, and cannot be set depending on the setting @1. After setting the number of stitches and sewing speed, turn on the button switch 6a of "iU tread".

Set the number display 2f for stitch numbers A and B to 4.4 using the button switch 5c, set the rocker switch 8b, turn it to the -”'; BJ side, and turn the “reverse stitch” frisch switch. Turn on 6m. Furthermore, after completing G-4 and H=4, in order to fully operate thread trimming, thread wiping, and presser foot lifting, rTRMJ is
Then, turn on the bush switches 6j and 61 of rWPJ and IKLTJ. The corresponding display lamps 7d7
71 lights up on m, 7j, 7. This completes the reverse stitching part G = 4. Since H=4 has been completed, when the button switch 9 for setting 1 is turned on, the display on the E-shaped display 2a of the pattern shop automatically changes from "1" to "2". Furthermore, the display on the numerical display 2c for the number of processes is "01", and since the set total number of processes is μA, B-C, D, E, F, and GH, there are 5 process phases, 1 [the larger phase is "06", which is the number On the display 2b, the numerical display 2C for the number of steps is displayed as "05" to "Ol". Further, the display lamps 7d, 7m, 73°7 and 71 all go out. This completes the setting of the sewing pattern shown in FIG. 3(a). Next, the throwing shown in (b) of the figure will be explained. The sewing pattern (b) has a repeat part of the previously set process in the middle of the sewing pattern. (
Considering that the sewing pattern (b) is set after the sewing pattern (a), the number display of the pattern Todoroki for the sewing pattern (a) will be ``2''.

Setting of A=10 and B=50 of sewing IA pattern in (b)?

However, rocker switch 8J1 that sets reverse stitching at the beginning
must be defeated by r7-, J11. Now, C.
The setting of the platform where -50 is repeatedly sewn is as follows. 11 The number of stitches and setting speed are the same as in other cases 2
, C. For these settings, turn on the "Continuous" button 6aτ and turn on the display lamp 7a. Furthermore, turn on the button switches 6b and 6e of the front step J and reUTJ (or 1-c(,)Ml), turn on the display runshifts b and 7e of -friL, etc., and turn on the button switch for the manual cent. When 9 is turned on, C-50 is set as the process in which reverse stitching is performed. As a result, the pedal sensor PD
The step C-50 is repeatedly sewn every time the front protection switch 8 is turned on. To terminate this repeated sewing without any need to do so, press the loose/knot switch t of the pedal sensor PDS.
The sewing machine is turned on and the step E=i0 is performed by sewing. What happens when setting E=10 using the h method described above?

Next, the sewing pattern in FIG. 3(C) differs from the other patterns (a) and (b) in that step 30 in B is a reverse stitching step. In this case, [front step J, 1-CUT
In addition to J (or rcOMJ), the button switch 6g of rBTJ is turned on, and its display lamp 7g is turned on. As a result, in the process of B=50, i
The sewing pattern on the main body MA is actuated by the control device CB, and reverse sewing is performed.

As described above, when the three sewing patterns (a), (b), and (C) have been set, the number displays 2a, 2b, and 2c for the pattern, the total number of steps, and the number of steps are displayed, respectively. , r4J r12J rolJ.

The pedal sensor PDS is set to the neutral position where neither the front pedal switch nor the pick-up switch is on, rlLK, L, fcQ.
Settings can be made by lighting up the display lamp 7c. If you turn on this "neutral" button 7 and then turn on the upper fill push switch f-6 (or the lower push switch f-6h), the indicator lamp 74 (or 7h) will light up. Light up. This setting defines the neutral position ttit, <up or down. If this "ψ meeting [1] is never set in one sewing pattern, it will be neutral and F will stop at K, and once the power is set, it will be valid for A within that sewing pattern. , it is sufficient to set the number of times for one sewing taste once.

The pattern successive button switch 11 is only for checking the existing alternating stitch pattern, and when turned on, the pattern is displayed. The push switch for continuing the process is used to display all the preset processes.

The full set tap lamp 3 indicates whether all the set processes have reached the level that can be set by the pre-pattern sewing device.

The setting error tab lamp 4 is a rung that indicates whether or not the setting contents are incorrect. 1JrIIL" lights up when both switches are turned on in the same process.

After the sewing pattern has been set as described above, the pattern sewing force is sequentially applied each time the front switch or the route switch of the pedal sensor PDS is turned on.

When turned on, the process setting process starts. When any of the bushing switches 68 to 6m is turned on, one of the corresponding display rungs 7a to 7m lights up. Friend, when you turn on the bush switches 5a-5C: df, t7, the numbers displayed on the number table nodes i2d-2f will go up one by one depending on the number of times you turned them on.

After "9" is displayed, it returns to "0".

In the first pattern successive process, the M focus of the sewing horizontal direction that has already been set is checked, and if there is no M focus, the 1 μm process will not be performed. The preset sewing pattern holder will display all the contents that have been set up.Assuming that the number display 2a of the pattern holder before this process is 1-2, the pattern shop's ridge'-I: The display for Kinobudake 2a is [1], and the contents of the pattern shop fil are displayed. The contents displayed at this time are those set by the process setting process. Pattern shop "1" consists of several processes, and the process displayed at this time is the process number "l". Therefore, the display of the number display 62c for the number of steps is "Ol", and accordingly, [6) of the number display 2b of the total number of steps set 1] is also displayed. In this way, the pattern successive process only involves the initial stage of the general process of the slow pattern, so the relevant sewing! When looking at each process set in Building I, it is necessary to start the process 5fft by operating the process successive button switch 1O, and to 0 by the output process.

In the process setting process shown in FIGS. 11 to 13, first, it is checked whether the process that is currently being set is still set. ．． 1 Turn on the full set lamp 3 to complete this process.
