Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen setting method for an injection molding machine, and more particularly, an injection molding machine in which an operator (operator) can set and change operating conditions by a screen setting section of a display screen. Screen setting method.

[0002]

2. Description of the Related Art A conventional injection molding machine is provided with a screen setting display means for displaying operating conditions of a machining process on a display screen. The screen setting display means switches the progress of the machining process for each process on the display screen, and displays various kinds of display screens. An operator who operates the injection molding machine can change the operating conditions of a plurality of factors in a plurality of screen setting units displayed on the display screen.

A specific example of the injection molding machine is an injection molding machine which forms a molded product by using a molding material such as a resin material. The injection molding machine has respective screen display portions for displaying operations such as injection, pressure holding, screw rotation, mold opening, mold closing, ejector (projection), suck back, and the like. The screen display section displays the set factors such as speed, position, pressure, and time. These factors are diverse. The display screen includes various types of screens such as an injection / plasticization screen and a mold opening / closing / ejector (projection) screen. Further, each factor to be set by the screen setting unit is also mixed in a plurality of display screens.

Therefore, in the injection molding machine, a plurality of display screens are required to display the screen setting section. Moreover, factors such as speed, position, pressure, and time during their operation are displayed in multiple stages and set.

3 and 4 show a typical example of a conventional screen setting method for an injection molding machine. As a display screen,
FIG. 3 shows an example of the injection / plasticizing screen, and FIG. 4 shows an example of the mold opening / closing / ejector (projection) screen. Numerical values indicated by numerals in the rectangular blocks in FIGS. 3 and 4 indicate the numerical values set for each factor. As shown in the injection / plasticization screen shown in FIG. 3, in the screw rotation operation,
The "screw rotation speed" and the "screw switching position" during the operation of the "screw rotation speed" are displayed on the screen setting section. Further, the "injection speed" is such that the factor of the speed is switched to a numerical value of four levels. These "injection speeds"
And the "injection speed switching position" during injection are set numerically.
Is displayed. For example, when the "injection speed" is 95.0, the maximum "injection pressure" during filling is set to 60.0% and limited. In addition, other "suckback speed" and "suckback position" are also set and displayed.

Further, the injection molding machine has a step of "holding pressure" for changing the "injection pressure". In Figure 3,
In the "holding pressure" screen setting section, a pattern is illustrated in which the pressure is first increased and then gradually decreased.

In the mold opening / closing / eject screen shown in FIG. 4, there is a "mold closing speed" and a "mold closing speed switching position" in the middle of the "mold closing speed" in the mold closing process.
Is also set and displayed. Further, the "mold opening speed" sets and displays the speed factor as low speed, high speed, and low speed, and the "mold opening speed switching position" is also switched to each set numerical value. in this way,
In the "mold opening / closing screen", it is necessary to display the "mold closing speed", "mold closing speed switching position", "mold opening speed", "mold opening speed switching position", and "mold clamping force (or pressure)". is there.

Further, it is necessary to eject after the mold is opened. In the injection molding machine, the "projection speed" is set in two stages and switched, and the "projection speed switching position" in the middle of the "projection speed" is set. It is also necessary to set the “projection speed”, the “projection speed switching position”, and the maximum “projection position”. Further, "return speed", "return speed switching position" of "return speed", and "projection number" are also displayed.

Further, in recent years, it has been practiced to advance the ejector during injection to help prevent gate cuts and sink marks. Therefore, in this example, this is referred to as "projection after injection". In "Projection after injection", "Start time",
"Projection speed" is set and displayed. Further, the “start time”, “return time”, and “return speed” in the return of “projection after injection” are set and displayed. Also for this, it is necessary to display "start time", "projection time", "projection speed" (sometimes projection "pressure" is adopted), and "return time" after injection.

[0010]

However, in the injection / plasticization screen of the display screen, "screw rotation speed",
"Injection speed", "Suck back speed", "Pressure retention time",
"Screw switching position", "Injection speed switching position" and "Suck back position" are mixed in the same display screen and
There is a problem that it is difficult to see because it is necessary to add a character at the XX time and YYY position, or a character expression by a number such as sec or mm, or each block of each factor.

Further, in the injection molding machine, it is necessary to switch from the "injection / plasticization screen" to the "projection" screen and set in correlation with both screens. Although not shown, the mold clamping force is increased after injection. It is necessary that the injection compression or the like that is compressed by straddling another display screen can be set in a short time.

Further, as shown in FIG. 5, in the injection molding machine, there are some which display the entire function such as "injection" and "screw rotation" on the display screen to show the action direction thereof, but both of them are shown. It is necessary to have a segmental expression of factors such as velocity and pressure.

Certainly, there is one in which colors and figures such as speed and pressure are divided on one screen, but at least "speed" is displayed on all screens even though there are multiple screens.
The frequently used factors such as “pressure”, “time”, and “position” were not consistently expressed in the same section.

Therefore, the operator could not recognize at a glance which screen setting unit the numerical value to be set is.

Therefore, an object of the present invention is to select factors of a screen setting section that are used across various types of display screens and are mixed in various types of display screens. An object of the present invention is to provide a screen setting method for an injection molding machine, which is displayed by figures or colors and is easy to understand and easy for unfamiliar people to handle, and has a display function for preventing operation mistakes.

[0016]

According to the present invention, there is provided a setting screen display means for displaying a plurality of display screens, respectively.
In a screen setting method of an injection molding machine for setting operating conditions based on the display screen of the setting screen display means, a screen setting section having at least factors of speed, position, pressure and time displayed on the display screen. Are displayed separately according to figures and / or colors, and the screen setting section, which is highly mixed with the plurality of display screens, is consistently displayed in the same display section on all of the plurality of display screens. The screen setting method of the injection molding machine can be obtained.

Further, according to the present invention, the screen setting section has at least a speed segment for setting a velocity, a position segment for setting a position, a force segment for setting a force, and a time segment for setting a time. The screen setting method for an injection molding machine according to claim 1, wherein the plurality of display screens include at least an injection / plasticization screen and a mold opening / closing / ejector screen.

[0018]

According to the screen setting method in the injection molding machine of the present invention, a plurality of display screens such as an injection / plasticizing screen and a mold opening / closing / ejector screen are switched and displayed on the screen setting display means. When changing the molding conditions (operating conditions) by the operator (operator) who operates the injection molding machine, the setting changes such as changing the "speed" or the "pressure" can be consistently performed on any display screen. Then, each factor such as "speed" and "pressure" is set and displayed by using the screen setting unit displayed by figures and / or colors.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the screen setting method for an injection molding machine according to the present invention will be described below with reference to FIGS. In this embodiment, the present invention will be described using the example of the injection molding machine described with reference to FIGS. 3 and 4 and also using the display screen, each factor of the screen setting unit, and the set numerical value.

The characters in the screen setting section shown in FIGS. 1 and 2 can be reduced from the characters shown in parentheses for the reason described later.

The injection molding machine is provided with a screen setting display means for displaying the working process and the operating conditions during the working process on the display screen. In this injection molding machine, the molding material supplied from the hopper is kneaded by the screw and sent to the tip portion, and in the process, a uniform plasticized state is generated by heat from the heating cylinder and frictional heat inside the molding material. When a certain amount of molding material accumulates at the tip of the screw, the screw stops and the molten molding material is injected at high pressure into the mold closed by the mold clamping device. The molding material is solidified with the mold clamped to become a product, and the mold is opened and taken out.

As described above, in the injection molding machine, there are various factors set in the screen setting section such as injection, pressure holding, screw rotation, mold opening, mold closing, ejector (projection), suck back, etc. as operations. Factors such as speed, position, and pressure during these operations are set in multiple stages according to operating conditions, and there are various types of display screens such as injection / plasticization screens and mold opening / closing screens.

Therefore, in the present invention, when the operator (operator) operating the injection molding machine changes the molding condition (operating condition), the setting of whether to change the "speed" or the "pressure" is set. Since there is an intention to change it, if each factor such as "speed" and "pressure" is consistently classified and classified by figure and / or color on every display screen, it is very easy to understand and there are few mistakes. I focused on that.

The display screen shown in FIG. 1 shows an example of the injection / plasticizing screen, and FIG. 2 shows an example of the mold opening / closing / ejector (projection) screen.

With reference to FIGS. 1 and 2, a plurality of display screens such as an injection / plasticizing screen and a mold opening / closing / ejector screen are switched and displayed on the screen setting display means. On the display screen, in each screen setting section, the factor of the linearly moving speed is displayed and displayed by the graphic of the speed division A, and the direction of the speed division A is also divided by the graphic. In the speed segment A, one of the left and right sides of the rectangular block shown in the figure is drawn in a horizontal V-shape so that the speed display and the direction display can be recognized.

Further, in the present embodiment, the screen setting portion displays the screw rotational speeds that rotate and move the screws in the form of rotational speed classification B. Rotation speed category B
Draws one of the left and right sides of the rectangular block shown in the figure in a substantially semi-circular shape so that the speed display and the direction display can be recognized.

Similarly, the factors of pressure or force and the directions of action of these pressures or forces are indicated by force category C.
In the force division C, one of the left and right sides of the rectangular block shown in the figure is drawn in a substantially horizontal W shape so that the force display and the direction display can be recognized. The position factor is
It is divided by the position division D. In the position division D, the position display can be recognized by a rectangular block shown by a figure. The time factor is divided into time segments E. In the time segment E, the display can be recognized by straight lines extending diagonally from the four corners of the rectangular block shown in the figure. The number of protrusions F is also classified. The number of protrusions F is drawn in a horizontal V-shape on the left and right of the rectangular block shown in the figure so that the number of times and the direction of the display can be recognized.

Each of the above display categories is represented in the same manner over a plurality of display screens (all screens), and the unit is speed A,
B is a percentage of the maximum value, and pressure C is also a percentage of the maximum value.
, The position D is set to mm, and the time E is set to several seconds. The number of protrusions F is an unknown number.

As shown in the injection / plasticization screen of FIG. 1, the screw rotates to store a quantity of molding material, and at the beginning, it is slow, fast, and prevents overrun to prevent gas mixture. Therefore, in order to operate slowly, the "screw rotation speed" and the "screw switching position" are set in the screen setting section as factors of the screen setting section. "Screw rotation speed" is 20.0,60.0,
5.0, "screw rotation switching position" is 4.0, 5
It is set to 0.0, 53.0. The stop position at which the screw rotation stops is 53.0.

After the screw rotation stops at the stop position indicated by 53.0, the screw is retracted without rotating to prevent drooling. This reverse speed and stop position are set. From this position, the screw advances in the next shot to inject the molding material, but many injection molding machines employ multi-stage injection. In the example shown in FIG. Factors are set and displayed in four stages such as 62.0, 95.0, 10.0 and 5.0 in four rectangular blocks. These “injection speed” and “injection speed switching position” during injection are 52.0, 8.0,
Setting as 2.0, the maximum "injection pressure" during filling is limited to 60.0% when the "injection speed" is 95.0. This "injection pressure" prevents burr of the molded product after molding. The "suckback speed" is 10.0,
The "suck back position" is set to 56.0.

When the molding material becomes almost full in the mold by the injection, a process called "holding pressure" in which the "injection pressure" is changed over time while the contraction of the molding material is not finished is reached. In Fig. 1, in order to prevent residual strain, and immediately after the molding material filled in the mold is filled to prevent backflow from the gate, the "holding pressure" factor in the screen setting section is set to a high value of 45.0. However, a pattern of gradually decreasing like 23.0 and 10.0 is illustrated. Here as well as the "holding pressure", the factors of the holding time are 1.2, 3.
As 5, the "holding time" and the "holding pressure" are displayed separately.

The mold opening / closing / eject screen shown in FIG. 4 will also be described. In the mold closing process, if a mold closing start is performed at a high speed, a shock will occur. Therefore, the factors of the "mold closing speed" in the screen setting section are low speed and high speed such as 20.0, 70.0 and 10.0, and then low speed for the mold protection. There is a “mold closing speed switching position” such as 10.0 and 90.0 in the middle of. Further, if the “mold clamping force” is too large, gas escape becomes worse and there is an appropriate mold clamping force, so the “mold clamping force” is set to 80.0 as in the example of FIG.

Further, the "mold opening speed" is also 10.0,7.
5, 15.0 for low speed, high speed, and low speed, and the "mold opening speed switching position" is also switched for 5.0, 85.0, 99.0 to protect the first molded product from damage and the last mold flow. The accuracy of the stop position due to is improved, and the accuracy of the stop position due to the last mold flow is improved. When the electric molding machine of the injection molding machine is adopted, the pressure becomes current or torque.

Ejection is required after the mold is opened. In an injection molding machine, if the protrusion is made at a high speed, the bite into the molded product becomes stronger. Therefore, change the factor of "protrusion speed" in the screen setting section in two steps, such as 50.0 and 10.0.
Set the "projection speed switching position" in the middle of the "projection speed" to 30.
0, 35.0 is set, and the factors of "projection speed", "projection speed switching position", and maximum "projection position" are set and displayed. The factor of "return speed" is 6
It is set to 0.0 and 15.0, and the factor of "return speed switching position" of "return speed" is set to 18.0 and 15.0.
Furthermore, the “number of protrusions” shown in FIG. 3 is indicated by 2.

It is also practiced to advance the ejector during injection to help prevent gate cuts and sink marks. In this example, this is referred to as "projection after injection".
The “start time” factor of “projection after injection” is 3.0 and the “projection time” is 1.0. The "projection speed" in this case is 2
It is set to 0.0. The "start time" in the return of "projection after injection" is 4.0, and the "return time" is 1.0,
The "return speed" is 20.0. Also in this case, the “start time”, “projection time”, “projection speed” (sometimes the projection “pressure” is used) and “return time” after injection are displayed.

Note that, as shown in FIGS. 1 and 2, the screen setting unit is consistently divided and expressed by the graphic and / or the color on every display screen, so that a part of the characters is reduced. However, since the display of speed, direction, time, force, etc. can be recognized, the characters in parentheses shown in FIGS. 1 and 2 can be reduced.

Although the injection molding machine is used as an embodiment as described above, the screen setting method of the present invention is not limited to this, and casting, welding, cutting, plastic working, cutting, abrasive processing, surface treatment, machine tool. , And can be widely applied in fields such as automatic production system equipment.

[0038]

As described above with reference to the embodiments,
According to the screen setting method of the injection molding machine of the present invention, the setting display portions of a plurality of display screens are displayed by figures and / or colors, and factors that are mixedly used in various display screens are selected. By displaying figures or colors by color on all frequently used display screens, it is possible to minimize the attachment of characters, and to make it clear and easy to understand.

Further, the operator can see the functions of the set categories at a glance, and can prevent an operation error. Furthermore, a person such as an administrator who is unfamiliar with the operation can learn the operation in a short time, and it becomes easy to support even when there is no dedicated person.

Further, when the screen setting method of the present invention is adopted in the injection molding machine, it is easy to set the other screens such as injection compression that uses mold clamping for injection compression and eject gate cut during injection, and it is possible to respond quickly.
