However, the above-mentioned conventional sewing device is limited to a plurality of sewing data in the range that it is not necessary to replace the cloth by the cloth press mechanism, so-called continuously. Therefore, when sewing according to a plurality of sewing data beyond the range of the cloth-pressing frame, it is necessary to release the state of pressing cloth with this frame halfway, and position the frame for cloth-pressing at the desired position of the user of the sewing device. position and perform the operation of correcting the press cloth again.

As a result, there is a problem that the sewing operation cannot be made more efficient and faster due to the cloth replacement work using the cloth press mechanism.

In addition, the above-mentioned conventional sewing device has a problem that it is difficult to increase the efficiency and speed of the sewing operation due to the need to input or designate a plurality of new sewing data when the cloth is replaced by the presser mechanism.

Contents of the invention

The object of the present invention is to realize high efficiency and rapidity of sewing work.

The sewing device according to claim 1 of the present invention includes: a sewing machine head having a needle drive mechanism for driving the needle up and down, a cloth pressing mechanism for pressing the object to be sewn, and a positioning mechanism for positioning the needle relative to the object to be sewn , and the platen for placing the sewn object, and the conveying mechanism for conveying the sewn object on the platen, and the input mechanism for inputting the settings related to sewing, and storing the sewing data for determining the sewing pattern, The cloth pressing mechanism continuously presses the cloth and is assigned a plurality of sewing data that should be sewn. A plurality of sewing data in the sewing data is called "individual sewing data") or continuous sewing data to control the sewing motion control mechanism.

In addition, the input means adopts a structure that receives a plurality of continuous sewing data or a combination of continuous sewing data and individual sewing data (individual sewing data), and the order in which these sewing data are sewn , and input the conveying amount when using each sewing data or continuous sewing data for sewing and shifting, and store these input contents in the storage mechanism, and the action control mechanism executes sewing sequentially according to the order stored in the storage mechanism data (individual sewing data) or continuous sewing data, and control the action of the presser mechanism and the above-mentioned conveying mechanism according to each sewing of the sewing data (individual sewing data) or continuous sewing data.

In the above-mentioned structure, the data for generating the sewing data may be set and input by the input means, or the sewing data stored in advance may be input into the storage means by other means of the input means. In addition, the same applies to the continuous sewing data.

The input mechanism designates a combination of continuous sewing data or individual sewing data of continuous sewing data together with the sewing order. In this case, designation may be a combination of a plurality of continuous sewing data, or a combination of one or a plurality of continuous sewing data and one or a plurality of individual sewing data.

The motion control means starts sewing according to the continuous sewing data or the individual sewing data in a specified order while referring to the storage means. Use the positioning mechanism to determine the position of the needle and the fabric in sequence, and use the needle drive mechanism to perform the needle's downward movement, so that when sewing is individual sewing data, it is the individual sewing data specified by the data. The needle entry position, and, in the case of continuous sewing data, the needle entry position specified by the sewing data contained therein.

In addition, when the sewing object has continuous sewing data, the cloth press mechanism keeps the pressed state, and sequentially performs sewing using a plurality of sewing data contained therein.

And, with the above-mentioned structure, since in order to carry out each sewing according to individual sewing data or continuous sewing data, it is necessary to transport the sewn object and change the sewing position, so it is necessary to correct the pressing of the cloth by the cloth pressing mechanism. Therefore, when the individual sewing data or continuous sewing data are sewn by the motion control mechanism, the sewing operation is temporarily interrupted, the pressing state of the cloth pressing mechanism is released, and the cloth is conveyed with the set conveying amount by the conveying mechanism. Perform next sewing with continuous sewing data or individual sewing data.

Therefore, a series of sewing consisting of a combination of a plurality of continuous sewing data or a combination of continuous sewing data and individual sewing data can be continuously performed on the to-be-sewn object without troublesome hands of the user.

The second aspect of the present invention has the same structure as that described in the first aspect of the present invention, and further has a display mechanism for displaying whether any of the sequential sewing data or the sewing data of which order is specified is being sewn. , and during the sewing of the continuous sewing data, it also displays whether any of the sewing data included in the continuous sewing data is being sewn.

With the above-mentioned structure, can play the same effect as 1 of the present invention, and when sewing according to any continuous sewing data, can designate as the display of the continuous sewing data in sewing, and be used to designate the continuous sewing data. Whether any one of the continuous sewing data is being sewn is displayed on the display mechanism. In addition, when sewing is performed according to any one of the individual sewing data, a display designating the individual sewing data being sewn is displayed on the display means.

(invention effect)

In the first aspect of the present invention, since input information such as a combination of a plurality of continuous sewing data or a combination of continuous sewing data and individual sewing data is stored in advance, it is possible to use the pressing mechanism for each sewing data to correct the pressing and automatically The conveying of the object to be sewn can be carried out in an efficient manner, so the conventional work of correcting the cloth pressing by the user and the movement and positioning of the object to be sewn are canceled. Setting input or next action instruction input enables rapid and efficient sewing.

In addition, sewing processing using a plurality of continuous sewing data, which cannot be performed conventionally, can be realized as a series of processing, and further efficiency and speedup of sewing operations can be realized.

In addition, even if there are many sewing processes to be performed on a fabric according to continuous sewing data or individual sewing data, it can be summarized as a series of sewing data groups to set and input, so as to reduce the frequency of setting and input. Realize the continuous operation, and further realize the rapidity and high efficiency of the operation.

The second aspect of the present invention also has a display mechanism. Since the display mechanism designates and displays the continuous sewing data in the current sewing and the sewing data contained therein or the individual sewing data, the operator of the sewing device can immediately understand The process currently being sewn.

Then, the sewing machine motor 32 is driven, and the CPU 101 again performs sewing according to the current count value n, referring to the nth sewing data registered in the combination data (step S4). Specifically, when sewing is performed according to the continuous sewing data of continuous sewing pattern No. 1, sewing is performed according to the sewing data of sewing pattern No. 1 included therein. Also, the cutter driving solenoid 74 is driven once to a plurality of times corresponding to the buttonholes to be formed to form buttonholes on the cloth.

In addition, at this time, the current continuous sewing pattern No. and the sewing screen G8 ( FIG. 22 ) indicating the currently sewn sewing pattern No. contained therein and its contents are displayed on the operation panel 4 .

And, when the sewing of the sewing pattern No. 1 which is the first sewing data included in the continuous sewing pattern No. For the set cloth feed amount value of the next sewing pattern No. 2, the cloth is moved in the Y-axis direction by the cloth clamp 42 (step S5).

Then, when the cloth is conveyed, the sewing machine motor 32 is driven again, and the COU 101 performs sewing according to the sewing data of the sewing pattern No. 2 included in the continuous sewing data of the continuous sewing pattern No. 1 which is the current count value 1 Sewing (step S6).

At this time, a sewing screen G8 ( FIG. 23 ) showing the current continuous sewing pattern No. 1 and the sewing pattern No. 2 included therein and currently being sewn and its content is displayed.

When the sewing of the sewing pattern No. 2 is completed, the sewing machine motor 32 is stopped. Then, the presser foot lifting solenoid 44 is driven to move the cloth presser frame 42 upward (step S7). In this way, the sewing of the first continuous sewing pattern No. 1 is completed. Then, the CPU 101 adds 1 to the count value n (step S8).

Then, the cloth is conveyed in the X-axis direction according to the set conveying amount by driving the respective conveying pulse motors 25 of the conveying mechanism 20 (step S9).

Moreover, CPU101 performs display of sewing screen G8 (FIG. 22) as mentioned above. Among the numbers of the continuous sewing pattern and the individual sewing pattern registered in the combination patterns displayed on the upper stage of the sewing screen G8, the second pattern is switched to a display indicating that sewing is in progress.

On the lower stage of the sewing screen G8, when the sewing data to be sewn is individual sewing data, detailed setting values of the sewing data are displayed. In addition, when the sewing data currently being sewn is continuous sewing data, detailed setting values of the sewing data currently being sewn in the continuous sewing data are also displayed.

Then, COU101 returns a process to step S3, and compares the count value n and the number of sewing data of combination pattern No. 1.

If the count value does not exceed the predetermined 3, the processing of steps S4-S9 is performed in the same manner as above, and the same processing of steps S3-S9 is repeated once again. In addition, when the count value n=4, the sewing is ended by the process of step S3.
