The following is displayed. That is, an error number corresponding to the error content is displayed on a 7-segment display on an operation panel provided for each sewing machine.

[0003]

However, when only the error number is displayed, the error number and the corresponding error content must be collated with a manual or the like. For this reason, it has been sometimes difficult for a beginner to quickly recover from an error. Therefore, it is conceivable to provide a liquid crystal display for each sewing machine and display the contents of the error in text, but the liquid crystal display is very expensive. In addition, a skilled person can easily and quickly recover from an error simply by looking at the error number. Therefore, when a liquid crystal display is provided for each sewing machine, the manufacturing cost of the programmable electronic sewing machine is unnecessarily increased. In view of the above, an object of the present invention is to make it possible for even a beginner to easily and quickly recover from an error without displaying an error when displaying an error generated in the programmable electronic sewing machine.

Or display the recovery method from the error. Therefore, the error display device can be shared by several sewing machines.

Although the factory equipment of the present invention is provided with a plurality of programmable electronic sewing machines, errors rarely occur in all the programmable electronic sewing machines at the same time, and errors occur simultaneously in a plurality of programmable electronic sewing machines. Even if an error occurs, each worker usually recovers from the error one by one. For this reason, even if the error display device is shared by several sewing machines, it does not particularly hinder the work.

In the present invention, since the error display device can be shared by several sewing machines as described above, the number of the error display devices is smaller than that of the programmable electronic sewing machine. Therefore, as compared with a case where an error display device is provided for each sewing machine, a relatively expensive error display device capable of displaying details of an error or the like (for example, the device according to any one of claims 1 to 3). However, even if is used, the equipment cost of the entire factory equipment can be sufficiently suppressed. Therefore, according to the present invention, even in the case of displaying an error that has occurred in the programmable electronic sewing machine, even a beginner can easily and quickly recover from the error without spending extra money.

In the programmer 71 and the sewing machine 1 configured as described above, based on the icons displayed on the LCD 73 and the operation states of the various switches 71a, the sewing program is prepared using the data read through the floppy disk drive 51. Can be created. When the start switch 27 is depressed after the program is created in this way, the CPU 85a outputs drive signals to the X-axis motor 21, the Y-axis motor 23, and the sewing machine motor 41, and the program is displayed on the work cloth 99. Perform sewing according to. In creating and inputting the above program,
Even if a complete program is created by the programmer 71 and then input to the sewing machine 1 via the external communication means 93 and 89, even if the data is input one by one when creating the program (for example, the coordinates of the starting point of sewing, etc.) ) May be input to the sewing machine 1 at any time.

When an error occurs during sewing according to the above program and the program cannot be continued, the CPU 85a executes the following error processing. FIG. 7 is a flowchart showing an error process executed by the CPU 85a at a predetermined timing when an error occurs. When the process is started, first, an error number is displayed on the 7-segment display 65 in S1 (S represents a step: the same applies hereinafter). That is, when an error occurs,
The CPU 85a determines the contents of the error by well-known processing of another routine based on the progress of the program and detection signals of various sensors (not shown). And in S1,

Therefore, even a beginner can easily grasp the contents of the error and the method of resetting, and can easily and quickly recover from the error. In the display in S7, only one of the error content and the return method may be displayed or only one of them may be displayed in advance by setting the selection switch.

The programmer 71 is detachably attached to the sewing machine 1. When the programmer 71 is attached to the sewing machine 1 in which an error has occurred, the contents of the error are displayed. For this reason, the programmer 71 can be shared by several sewing machines 1. That is, a factory facility such as a sewing factory generally includes a plurality of sewing machines 1 (for example, 10 or more). However, it is rare that an error occurs in all the sewing machines 1 at the same time. Even if the error occurs, each worker usually recovers from the error one by one. For this reason, even if the programmer 71 is shared by several sewing machines 1 such as three sewing machines for ten sewing machines 1, there is no particular trouble in the work.

The programmer 71 uses a relatively expensive LCD 73 capable of displaying the contents of an error or the like in text. The LCD 73 alone is relatively expensive. Can be shared. For this reason,
The equipment cost of the entire factory equipment can be sufficiently suppressed. Therefore, in the present embodiment, in displaying an error that has occurred in the sewing machine 1, without displaying extra money,
Even a beginner can easily and quickly recover from an error.

Since the programmer 71 is housed in a portable housing as shown in FIGS. 1 and 4, the programmer 71 is transported to the sewing machine 1 where an error has occurred, and is mounted on the sewing machine 1 to display the program. Can be performed very easily and quickly. Therefore, in this embodiment, it is possible to recover from the error more easily and quickly. Further, in the sewing machine 1, the error number is displayed on the 7-segment display 65.
You can also return from an error without using.

In the above embodiment, the programmer 71 corresponds to the error display device, the LCD 73 corresponds to the display section, the various switches 71a correspond to the program creating means, and the external communication means 89, 93 correspond to the input means. Also,
The present invention is not limited to the above embodiments, and can be implemented in various forms without departing from the gist of the present invention. For example, the programmer 71 as an error display device is configured to also serve as a device for creating and inputting a program.
It may be configured exclusively for displaying the details of the error or the return method, or may be configured to be shared with other devices. However,
In the programmer 71, since the above two types of devices are shared, programs can be individually created and input to a plurality of sewing machines 1, and furthermore, the cost can be further reduced. In the sewing machine 1, the presser foot device 15 is moved in the X and Y directions.
The present invention can be applied to various sewing machines such as a sewing machine that moves in the θ direction.
