Description

The present invention relates to a molding condition setting device in a molding machine, and more specifically, a numeric keyboard and a pulse generator are both provided as an input device for the molding condition setting value, and the setting value by the numeric keyboard is pulsed. The present invention relates to a molding condition setting device that can be finely adjusted by a generator.

There are a large number of molding conditions to be set by the molding machine, and there are both those that do not require such setting changes and those that require fine adjustment.

However, conventionally, when setting the molding conditions, the same number of digital switches as the molding condition items were set, but as described above, there are so many molding condition items that the setting of the digital switches is troublesome. The molding condition setting device was large.

Further, the device which is set by using the ten-keyboard can be made small.

However, in general, the numeric keyboard is such that the numerical value of the newly pressed key is moved to the least significant digit of the numerical value displayed on the display and each of the numerical values displayed earlier is incremented by one digit. For example, when the key 1 is pressed twice, 11 is displayed on the display, so that the lowest digit must be changed when adjusting the lowest digit of the set value.

In addition, the displayed numerical value before the change is also erased, which makes it difficult to use, and the set value cannot be continuously changed, which may cause a setting error.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a small-sized device, which can perform both rough setting and fine setting, and further set values continuously. It is an object of the present invention to provide a molding condition setting device that can be changed as desired.

Its features are: a display for digitally displaying the setting values of molding conditions, a selection switch for selecting a desired setting item and displaying the setting value on the display, and a setting value to be set. , Numerical value of the key to be newly pressed is moved to the lowest digit of the numerical value already displayed on the display unit, and each of the numerical values displayed earlier is incremented by one digit. The pulse generator that outputs the number of pulses and increases or decreases the set value displayed on the display from the least significant digit, and the ten-key keyboard or pulse generator that is operated first after the desired selection switch is turned on. Select either one and use the numeric keyboard or pulse generator output to change the set value displayed on the display, and the set value displayed on the display to control the molding machine. There is in the place where made by providing an input switch to input to.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the molding condition setting operation panel shown in FIG. 1, reference numeral 1 is a selection switch in which molding conditions to be set are described on the surface of the operation portion, and the same number as the molding condition item is provided. An LED 1a that is turned on when selected is embedded in the left shoulder on the surface of the operation portion of each selection switch 1.

Reference numeral 2 is an indicator arranged corresponding to the selection switch 1, and a 7-segment LED is provided for the number of digits required for each molding condition setting value in order to digitally display the setting value. Also, on the right side of the display unit 2, SEC,%, mm that indicates the unit of set value
The characters such as are described.

Reference numeral 3 is a ten-key keyboard for rewriting the set values displayed on the display 2. When the set value rewritten by the numeric keyboard 3 is returned to the set value before the rewriting, the correction switch 3a may be pressed, and is used in the case of an operation error or the like.

4 is a pulse generator for increasing or decreasing the set value displayed on the display 2 from the least significant digit.
50 pulses are generated for one rotation of the control knob.

Reference numeral 5 denotes a plasma display, which displays setting values corresponding to the selected selection switch and other necessary messages.

The changed set value displayed on the display 2 is input to the controller of the molding machine by operating the input switch 3b of the numeric keyboard 3 or the input switch 4a of the pulse generator 4.

In addition, the numeric keyboard 3 and the pulse generator 4 are the second
As shown in the figure, it is connected to each selection switch 1 via a counter unit 6, and this counter unit 6 operates the numeric keyboard 3 or the pulse generator 4 which is operated first after the selection switch 1 is turned ON. When the numeric keypad 3 is selected, the set value displayed on the display 2 is completely rewritten, and when the pulse generator 4 is selected, it is displayed on the display 2. The setting value is changed from the least significant digit to increase when the operation knob is rotated to the right and decrease when the operation knob is rotated to the left, and carry up or down.

When setting the molding conditions, first, the selection switch 1 corresponding to the molding condition to be set is turned on. When the set value displayed on the display unit 2 is to be changed largely thereafter, the selected value is changed to the changed selected value using the numeric keyboard 3.

On the other hand, when the set value displayed on the display 2 is to be finely changed, the operation knob of the pulse generator 4 is rotated rightward or leftward to increase or decrease the displayed set value from the least significant digit. . Since the number of the set value can be changed according to the rotation speed of the operation knob, the changing speed of the set value can be freely changed according to the intention of the operator, and the display on the display unit 2 shows 9999. In such a case, if the operation knob is rotated to the right, it is possible to make a large change in which 9999 is set to 0 in a short time.

After that, the changed set value displayed on the display unit 2 is
It is input to the control unit of the molding machine by pressing the input switch 3b or 4a.

As described above, according to the present invention, both the numeric keyboard for roughly changing the setting value and the pulse generator for finely changing the setting value when the setting value of the molding condition is input are provided. As a result, the molding condition setting device can be made compact, and the setting value can be changed roughly or finely.Furthermore, when changing the setting value finely using a pulse generator, the change can be made continuously. It can be performed with a simple analog feel, and is extremely easy to use in a molding machine having many molding condition items to be set, which is extremely effective.

Although the present invention has been variously described with reference to the preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. Is.
