Abstract

PURPOSE:To obtain an automatic typewriter capable of solving maloperation by self-diagnostic function by providing a position detector set to a driver using a motor and a solenoid as drive sources and a displayer to be interlocked with signals from the position detector. CONSTITUTION:In the Fig., showing a side view of the driver of a type box 1, the type box 1 using a motor 5 as a drive source is driven bilaterally, as shown by arrow in the Fig., by a ball screw 7 connected by a coupling 6. In the Fig., a flow chart of a self-diagnostic operation to test that the motor 5 is normally positioned by a distance designated is shown. After positioning 20cm to the right direction from the origin, when positioning is made to a place 20cm to the left direction, it should follow that the signal of an origin position detector 8, because it is in the origin after the completion of positioning, is in active state. If the signal of the origin position detector is in active state, normal processing, e.g., displaying of normality, etc., is made, whereas if it is in inactive state, abnormal processing, e.g., displaying of abnormality, etc., is made.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic typewriter 1, particularly a self-diagnosis device thereof, and its purpose is to test the operation of a drive mechanism using a motor and a solenoid as drive sources. shall be.

Conventional structure and its problems In conventional electronic typewriters or automatic type typewriters, the self-diagnosis function only tests the memory elements, etc., and operates the drive mechanism to check whether the drive mechanism is working properly. Since there is no inspection to see if it is working, if an abnormal condition occurs in the drive mechanism, normal positioning or normal operation will not be obtained, and the original function will not be achieved. At that time, the means to search for abnormal parts was extremely inconvenient as it required making the robot perform abnormal movements and then relying on intuition for the rest.

OBJECTS OF THE INVENTION The present invention provides an automatic type typewriter which solves the problems of the prior art by using a self-diagnosis function.

Composition of the Invention The present invention provides an automatic type type comprising a drive means using a motor and a solenoid as a drive source, a position detector installed in the drive means, and a display device linked to a signal from the position detector. By installing the above-mentioned position detector in the lighter, when a malfunction occurs, the abnormality can be immediately confirmed, which can greatly shorten the repair time.Also, by having the machine perform regular self-diagnosis, The reliability of automatic typewriters can be greatly improved.

DESCRIPTION OF EMBODIMENTS FIG. 1 is a schematic diagram showing the construction of an automatic type typewriter. In Figure 1, 1 is a type mold that stores type;
A platen 3 for fixing the 2-digit printing paper is a type bar for grasping type and printing on the printing paper on the platen 2, and 4 is a raised frame for transferring the type from the type mold 1 to the type bar 3.

In this structure Ω automatic type typewriter, several driving means can be considered, such as one in which the type 1 moves, one in which the type bar 3 moves, etc., but here, the type 1
An explanation will be given using an example of means for positioning by moving.

Figure 2 &-2 is a side view of the drive means of the type storage 1, with the type type 11-i motor 5 as the drive source and a ball screw 7 connected by a coupling 6 VC as indicated by the arrow in the figure. It is driven left and right. The motor 5 is composed of a servo motor or a stepping motor, and in the case of a servo motor, positioning control is performed in a closed loop using an encoder, etc., and in the case of a stepping motor, positioning control is normally performed in an open loop. In Fig. 2, 8,9°1o is an optical position detector, that is, a photointerlager, which is made active and inactive by a shielding plate 11, 8 is an origin position detector, and 9 is a negative direction IJ position detector. , 10 is a positive direction limit position detector.

As an example, the self-diagnosis flowchart for checking whether the motor 5 is correctly positioned by the commanded distance is shown in the third diagram.
As shown in the figure. In Figure 3, move 20 degrees to the right from the origin position.
If the positioning is performed 201 times to the left after 1 positioning, the signal from the home position detector 8 should be in an active state since the position is at the home position after the positioning is completed. If the signal from the origin position detector 8 is in an active state, normal processing such as displaying that it is normal is performed, and if it is in an inactive state, abnormal processing such as displaying that it is abnormal is performed.

An example of the display panel is shown in FIG. 12 in Figure 4
is a switch that performs self-diagnosis, and 131L to 1
3h is a display that displays the results of self-diagnosis.

An example of self-diagnosis around the raised frame will be explained as another -fl. Figure 5 is a diagram showing the configuration of the 4
14 is a thrusting frame, 14 is a thrusting frame drive unit, 16 is a thrusting completion detector that detects that the thrusting operation is completed, and 16 is a thrusting bar return detector that detects that the thrusting bar has returned. 17 is a shield plate for shielding the uplift completion detector 15 and the uplift return detector 16.

FIG. 6 shows a flowchart of a self-diagnosis to check whether the uplifting frame is pushed up normally and the uplifting completion detector 15 is in an active state. If the operation is normal, an ejection completion detection signal should be output after the ejection solenoid operation command is issued, and if there is no ejection completion detection signal, it is considered abnormal. If it is normal after the ascent is completed, there should be an ascent detection signal, and if this signal is not present, it is considered abnormal.

Effects of the Invention As described above, according to the self-diagnosis device of the present invention, it is possible to test whether or not the drive source is operating normally by detecting the operation of the position detector installed in the drive mechanism. Furthermore, by displaying the test results of each drive source on the display panel, abnormalities can be immediately discovered and repair time can be greatly shortened.
This has the great effect of improving the reliability of automatic type typewriters.
