Abstract

PURPOSE:To arrange a case body at an optional position by fixing the case body to an optional unit so as to be freely attached/detached without fixing the case body on a specific unit with a screw. CONSTITUTION:The case body 3 of a programmer device has a keyboard 1 and a display panel 2 on its front and a reversed U-shaped engaging projection part 4 drooping in the lower direction and a spacer member 5 are arranged on the upper part of its back. These projection part 4 and spacer member 5 are molded with a synthetic resin material similar to the material of the case body 3. The case body 3 allows said projections part 4 to engage with a rectangular hole 6a on the back of a specific I/O unit 6 so as to be fixed. Thus, the case body 3 can be arranged an optional position at the time of reconstitution of a programmable controller and the resetting of control data.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a programmer device for a programmable controller.

(Prior Art) A normal programmable controller is connected between a numerical control device and a machine tool via a motherboard, and is configured separately from the numerical control device (referred to as an NC device). It is equipped with a microprocessor, etc., which is located between the equipment and the machine tool area and is dedicated to performing various auxiliary tasks.

These programmable controllers can be used by changing the input/output modules installed on the motherboard.
Alternatively, it can be freely reconfigured by resetting control data in internal storage means such as RAM, and exhibits a specific control function corresponding to the machine tool to be controlled.

In this case, the programmer device used to rewrite and confirm the control data is generally installed at a specific location and fixed by screwing or the like.

FIG. 3 shows a power supply unit 12 arranged on the same motherboard 11 as five replaceable input/output units 10.
The programmer 13 is shown screwed to the back of the computer.

Such a programmable controller is generally stored in a locker, and since the power supply unit is usually replaced the least frequently, the programmer 13 is often fixed to the back of the power supply unit.

(Problem to be solved by the invention) According to such a conventional method of installing a programmer device,
While it is easy to set the control data each time you open the locker and replace a unit, the programmer's installation position is limited, which limits the placement of the motherboard within the locker, making the space inside the locker more efficient. or depending on its location,
There has been a problem in that it is inconvenient for the operator to use the programmer.

The present invention was made to solve the above problems, and
It is an object of the present invention to provide a programmer device for a programmable controller that can be installed in a freely movable manner without screwing the casing.

(Means for Solving the Problems) According to the present invention, in a programmable controller configured by disposing a plurality of units replaceably on a panel and in which specific control data is set, the control data is set. a housing provided with a key and a display panel for the purpose of reconfiguring the programmable controller or resetting control data; and fixing means for removably fixing the housing to each of the units. Accordingly, it is possible to provide a programmer device for a programmable controller, characterized in that the casing can be placed at an arbitrary position.

(Function) In the programmable controller programmer device of the present invention, the casing is removably fixed to any unit without being screwed to a specific unit.
When reconfiguring the programmable controller or resetting control data, the housing can be placed at any position.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing an example of a programmer device,
The same figure (a) shows the operating keyboard 1 and the display panel 2 provided on the front side, and the same figure (b) shows a type of fastening mechanism for fixing the device to a specific unit of the programmable controller. It shows.

In the figure, a keyboard 1 on the front surface of a housing 3 includes keys for numerical and special input, and a display panel 2 is composed of a liquid crystal display device or the like. An inverted U-shaped engagement protrusion 4 that hangs downward is formed at the center of the upper back surface of the housing 3.
A spacer member 5 is provided at the bottom. These protrusions 4 and spacer members 5 are molded from the same synthetic resin material as the housing 3, and function in the following manner in fixing the housing 3 to the back surface of a specific input/output unit.

That is, as shown in FIGS. 2(a) and 2(b), the engaging protrusion 4 has enlarged portions 4a and 4b on the outside of its two lower ends, and is bored at a predetermined location of the unit 6. , by fitting into the square hole 6a corresponding to the protrusion 4, the housing 3
is fixed to the rear surface of the unit 6 so that it does not come off easily. At that time, the spacer member 5 forms a gap with the back surface of the unit 6. Also, Fig. 2(b)
As shown in FIG. 2, the housing 3 is connected from its lower end to the connector position formed at the bottom of the unit 6 by a cable for transmitting control data. Furthermore, by changing the thickness of the spacer member 5 depending on the mounting position of the programmable controller, the operator can easily operate keys and inspect the display panel.

In the device of the above embodiment, holes corresponding to each unit constituting the programmable controller are formed, and an engaging protrusion is provided on the side of the programmer device, but the fixing means for fixing the casing is The snap structure may have a shape other than that shown in the drawings, or may be fixed by magnetic force, for example.
In short, if the installation positions of a plurality of interchangeably arranged units can be freely determined, there will be no inconvenience in effectively using the space regardless of the arrangement of the motherboard within the locker.

As described above, since various different embodiments can be easily constructed without departing from the spirit of the present invention, the present invention is not limited to specific embodiments other than the limitations described in the claims.

(Effects of the Invention) As explained above, according to the present invention, when used in a programmable controller, the degree of freedom regarding the installation location can be increased, and since it can be easily removed, it can be easily removed when stored. It is possible to provide a programmable controller programmer device that enables effective use of space within a locker.

[Brief explanation of the drawing]

Figures 1 (a) and (b) are front and rear perspective views showing one embodiment of the present invention, and Figures 2 (a) and (b) show the state in which it is attached to a specific unit of the programmable controller. FIG. 3, a partially sectional explanatory diagram, is a perspective view showing a programmer screwed to the back of a conventional power supply unit. DESCRIPTION OF SYMBOLS 1... Keyboard, 2...
