Description

  The present invention relates to an assisting device for adjusting an actuator mounting position, and by adjusting the mounting position of an actuator provided in a die of an extrusion molding machine, when roughly adjusting the slit interval of the die, It is designed to provide guidance on the appropriate mounting position adjustment amount.

  In the present specification and claims, a resin film and a resin sheet having a thickness greater than that of the resin film are collectively referred to as “resin film”.

As a technique for mass-producing a resin film made of a synthetic resin such as polyester, a melt extrusion method using a die is employed.
A resin film manufacturing plant for manufacturing a resin film by a melt extrusion method using a die is conventionally called an extruder or an extrusion molding system in the industry.

  Here, the extruder will be described with reference to FIG. The extruder 2 of the extrusion molding machine 1 supplies the molten resin to the die 3. The metal die 3 is provided with a lip portion that forms an elongated slit, and a thin resin film 4 is discharged from the slit of the lip portion. The width of the resin film 4 discharged at this time is 1 m, for example, and the film thickness is several mm.

The discharged resin film 4 is cooled by the cooling roll 5 and then stretched in the longitudinal direction (moving direction of the resin film 4) and the width direction (direction orthogonal to the moving direction of the resin film 4) by the stretching machine 6. . At this time, the width of the resin film 4a formed by stretching the resin film 4 is, for example, 10 m, and the film thickness is on the order of microns.
The thickness of the resin film 4a stretched in the vertical and width directions is measured by the film thickness measuring instrument 7 at a plurality of locations (for example, 800 locations) in the width direction of the resin film 4a.
And the resin film 4a by which the film thickness measurement was carried out is wound up by the winder 8. FIG.

  The control device 9 sets the slit interval of the slit of the lip part of the die 3 so that the film thickness measured by the film thickness measuring instrument 7 is uniform at each position in the width direction of the resin film 4a. It controls so that it may adjust in multiple places (for example, 40 places) of (the width direction of the resin film 4).

  In the above example, in the stretching machine 6, the film 4 is stretched in the longitudinal direction and the width direction. However, the film 4 may be stretched only in the longitudinal direction or only in the width direction, and may not be stretched.

  Next, the detailed structure of the die 3 and the means for adjusting the slit interval of the slit formed in the lip portion of the die 3 will be described.

  4 (a) is a cross-sectional view showing the configuration of the die 3, and FIG. 4 (b) is a view taken in the direction of arrow B in FIG. 4 (a) (in FIG. 4 (b), the heat bolt support portion 31 is Not shown).

As shown in FIGS. 4A and 4B, the die 3 is provided with a lip portion 3b that forms an elongated slit 3a (extending in the direction perpendicular to the paper surface in FIG. 4A). The lip portion 3b includes a movable lip 3b-1 and a fixed lip 3b-2, and a space formed between the movable lip 3b-1 and the fixed lip 3b-2 is a slit 3a. It has become.
The molten resin supplied from the resin supply path 3c is discharged as a thin resin film 4 from the slit 3a. Therefore, the film thickness of the resin film 4 is prescribed | regulated by the slit space | interval S of the slit 3a.

The die 3 is provided with a plurality of (for example, 40) heat bolts 30 along the width direction of the movable side lip 3b-1 of the lip portion 3b (the width direction of the resin film 4). One end side of each heat bolt 30 is rotatably connected to the movable lip 3 b-1, and the other end side is screwed to the heat bolt support portion 31.
The heat bolt support portion 31 is fixedly installed on the die 3.

  Each heat bolt 30 can move and expand and contract in the axial direction. That is, the axial position adjustment of each heat bolt 30 includes “rough adjustment” in which the heat bolt 30 is moved and adjusted in the axial direction, and “fine adjustment” in which the heat bolt 30 is expanded and contracted in the axial direction.

That is, by rotating the heat bolt 30 screwed to the heat bolt support portion 31 around the axis, the heat bolt 30 can be moved in the axial direction, and the position of the heat bolt 30 can be roughly adjusted (adjustment of the mounting position). .
Further, in a state in which the rotation of the heat bolt 30 with respect to the heat bolt support 31 is constrained, the heater provided in the heat bolt 30 is caused to generate heat through current, and the expansion and contraction in the axial direction is caused by the thermal expansion / contraction caused by the heat generation. Can be finely adjusted (adjustment in units of several μm).

  Thus, the pushing force with respect to the movable side lip 3b-1 changes as each heat bolt 30 moves and expands and contracts in the axial direction. That is, when the heat bolt 30 extends in the axial direction, the pushing force against the movable side lip 3b-1 is increased, and the slit interval S of the portion where the heat bolt 30 is provided becomes narrower. When contracted in the axial direction, the pushing force against the movable side lip 3b-1 becomes weak, and the slit interval S of the portion where the heat bolt 30 is provided becomes wide.

  The rough adjustment described above is performed manually by an operator. This rough adjustment is performed at the initial startup of the extrusion molding machine 1 or when the adjustment range becomes larger than the fine adjustment range after long-time operation.

Further, the fine adjustment described above, that is, control of the amount of current applied to the heater of each heat bolt 30 is performed by the control device 9. This fine adjustment is performed for the purpose of uniformly controlling the film thickness of the resin film 4a when the resin film 4 is continuously formed after the rough adjustment is completed.
That is, the control device 9 controls the amount of current applied to the heater of each heat bolt 30 so that the film thickness measured by the film thickness measuring instrument 7 is uniform at each position in the width direction of the film 4a. The slit interval S of the lip portion 3b of the die 3 is adjusted by controlling the amount of expansion / contraction (fine adjustment amount) of each heat bolt 30.

  In addition to the heat bolt system using a heat bolt as an actuator for adjusting the slit interval, a heater is provided in the lip portion 3b, and the resin discharge rate is changed by changing the resin viscosity discharged from the slit 3a by the heater heat. Thus, there are a lip heater method for adjusting the film thickness and a servo motor method for driving an adjusting bolt by a servo motor.

JP-A-1-295820 JP 2001-75635 A JP-A-9-300432 JP 2006-21413 A Japanese Patent Application No. 2005-073289

  The rough adjustment of each heat bolt 30 described above, that is, the adjustment of the mounting position of each heat bolt 30 in the axial direction is performed by the operator rotating each heat bolt 30 about its axis with a wrench.

When performing this rough adjustment, the operator looks at the film thickness measurement data (film thickness measurement data at a plurality of locations in the width direction of the resin film 4a) measured by the film thickness measuring instrument 7,
(1) Selection of which heat bolt 30 is roughly adjusted from among a large number of heat bolts 30;
(2) The rough adjustment amount (heat bolt rotation amount) of the selected heat bolt 30 is
Coarse adjustment work is performed based on experience.

Since experienced operators have abundant experience, the selection of the heat bolt 30 to be coarsely adjusted and the amount of coarse adjustment are appropriate.
However, an inexperienced operator cannot select the heat bolt 30 to be coarsely adjusted and the amount of coarse adjustment, and it is difficult to perform optimum coarse adjustment.

An example of a mistake made by an inexperienced operator is as follows, for example.
For example, when the film thickness measurement data at one specific location is larger (or smaller) than the film thickness measurement data at another location, only one heat bolt corresponding to the aforementioned “specific location” is used. Roughly adjust and try to extend (or shrink) in the axial direction.
However, since the die 3 is a metal structure, even if only one location is pushed in (or pulled), the slit interval S at that location does not change, and it is adjacent to this one location as a center. The slit spacing S cannot be optimally adjusted unless the plurality of heat bolts provided at the locations to be expanded and contracted, and the amount of expansion and contraction of each heat bolt is optimized and coarse adjustment is performed.

  The die 3 is a metal structure. When only one specific heat bolt (actuator) is roughly adjusted, mechanical interference occurs between adjacent heat bolts (actuators), and the actuator 3 There exists a problem of causing damage, performance degradation, and the precision degradation of the thickness of a resin film.

In addition, a display device that displays film thickness measurement data measured by the film thickness measuring instrument 7 is often installed in a cab or the like in which the control device 9 is disposed. The place (driver's cab) where this display device is arranged is different from the place where the die 3 is actually installed.
For this reason, the operator must check the film thickness measurement data in the cab, take notes, move to the vicinity of the die 3, and make rough adjustments of the heat bolt 30 while looking at the notes. That is, it is inconvenient because an operator near the die 3 cannot make rough adjustment while directly looking at the display device on which the film thickness measurement data is displayed.

  After all, rough adjustment of each heat bolt 30, that is, adjustment of the mounting position of each heat bolt 30 in the axial direction has been a difficult task in the past.

  In view of the above-described prior art, the present invention provides an assisting device for adjusting an actuator mounting position, which provides guidance and support so as to facilitate rough adjustment of each heat bolt, that is, adjustment of the mounting position of each heat bolt in the axial direction. The purpose is to provide.

In addition, when a heater equipped with a heat bolt is heated by current, and the axial expansion and contraction is finely adjusted (adjustment in units of several μm) by the thermal expansion and contraction of the heat bolt accompanying this heat generation, the film thickness measuring instrument Based on the film thickness measurement data measured by (film thickness measurement data at multiple locations in the width direction of the resin film), select the heat bolt to be expanded and contracted so that the film thickness of the resin film is uniform in the film width direction. And a program for fine adjustment for calculating “the amount of expansion / contraction” has already been developed (see, for example, Patent Documents 1, 3, 4, and 5).
The present invention provides an assisting device for adjusting an actuator mounting position that assists in facilitating rough adjustment by utilizing a program developed for fine adjustment.

The configuration of the present invention for solving the above problems is as follows.

In the present invention, when the film thickness measured by the film thickness measuring device is sent to the guidance device, the guidance device is required to make the film thickness distribution in the width direction of the resin film uniform based on the measured film thickness. A thickness adjustment amount and an actuator adjustment amount obtained by converting the thickness adjustment amount are obtained. The actuator adjustment amount is displayed on the display device.
Therefore, the operator can easily adjust (roughly adjust) the mounting position of the actuator only by adjusting the mounting position of the actuator by the amount of actuator adjustment displayed on the display device.

  The best mode for carrying out the present invention will be described below in detail based on examples.

  FIG. 1 is a block diagram showing a support device 100 for adjusting an actuator mounting position according to an embodiment of the present invention.

This support device 100 is applied to an extrusion molding machine 1 as shown in FIG. In the present embodiment, description will be made on the assumption that the heat bolt 30 (see FIG. 4) is used as an actuator for adjusting the slit interval S of the die 3 in the extrusion machine 1 that is an application target.
In this case, it is assumed that 40 (No1 to No40) heat bolts 30 are attached to the die 3.

The assisting device 100 for adjusting the actuator mounting position according to this embodiment includes a guidance device 200, a terminal display device 300, a heat bolt position detecting device 400, and a film thickness measuring device 500.
Among these, the guidance device 200 is installed in a position near the die 3 (a position where the operator can visually recognize the work while turning the heat bolt 30 with a wrench) or in a cab away from the die 3.
The terminal display device 300 is a portable device that can be carried by an operator.

The heat bolt position detection device 400 includes a heat bolt position sensor 401 and a transmitter 402. The heat bolt position sensor 401 is a sensor that detects attachment positions (coarse adjustment positions) P1 to P40 in the axial direction of the heat bolts 30 of No1 to No40. The heat bolt position sensor 40 detects a rough adjustment position of each heat bolt 30 by image processing, or detects a mounting position of each heat bolt 30 by a position sensor individually arranged on each heat bolt 30. .
The detected mounting positions P1 to P40 are transmitted as radio signals by the transmitter 402.

The film thickness measuring device 500 includes a film thickness measuring sensor 501 and a transmitter 502. The film thickness measurement sensor 501 detects film thicknesses t1 to t800 at 800 locations in the width direction of the resin film 4a stretched in the vertical and width directions.
The detected film thicknesses t1 to t800 are transmitted as radio signals by the transmitter 502.

The receiver 201 of the guidance device 200 receives the attachment positions P1 to P40 and the film thicknesses t1 to t800.
The guidance device 200 performs the following processing based on the received mounting positions P1 to P40 and film thicknesses t1 to t800.

The thickness distribution calculation apparatus 202 divides the 800 film thicknesses t1 to t800 into 40 groups including a set of adjacent ones according to mapping information M set in advance, and average film thickness for each group. T1-T40 is calculated | required and thickness distribution (profile) PR of the width direction of the measured resin film 4a is calculated | required from this average film thickness T1-T40.
The mapping information M is information that determines how the film thicknesses t1 to t800 are grouped. For example, the first group has film thicknesses t1 to t12, the second group has film thicknesses t13 to t20, and the third group. The groups are grouped into film thicknesses t21 to t30.

The thickness adjustment amount calculation device 203 compares the thickness target value O obtained by calculation with the thickness distribution PR, and calculates the thickness adjustment amounts Δ1 to Δ40 that make the film thickness of the resin film 4a uniform at each point in the width direction. Ask. That is, the thickness adjustment amounts Δ1 to Δ40 are calculated so that the deviation between the thickness target value O and the thickness distribution PR becomes zero.
That is, the thickness adjustment amounts Δ1 to Δ40 such that the thickness distribution PR matches the thickness target value O by adjusting the axial mounting positions of the 40 heat bolts 30 by the thickness adjustment amounts Δ1 to Δ40, respectively. Ask for.

Note that the software for obtaining the thickness adjustment amounts Δ1 to Δ40 based on the thickness target value O and the thickness distribution PR is a program (for example, a program developed to finely adjust the axial expansion / contraction position of the heat bolt 30 by thermal expansion / contraction. Patent Literatures 1, 3, 4, and 5) are incorporated.
The thickness target value O is obtained by dividing the difference between the maximum value and the minimum value of the film thicknesses t1 to t800 by the average value of the film thicknesses t1 to t800. Alternatively, the thickness target value O may be preset.

The adjustment amount conversion device 204 converts the thickness adjustment amounts Δ1 to Δ40 that are the attachment positions in the axial direction of the heat bolts 30 into heat bolt adjustment amounts h1 to h40 that are the rotation amounts of the heat bolts 30. The heat bolt adjustment amounts h1 to h40 represent the rotation amount in the number of right rotations (positive rotation) or the number of left rotations (negative rotation).
For example, among the thickness adjustment amounts Δ1 to Δ40, only Δ7, Δ8, and Δ9 are necessary as adjustment amounts, and when other adjustment amounts are zero, out of the heat bolt adjustment amounts h1 to h40, h7, Only h8 and h9 are converted and output.

  Moreover, as will be described later, when the mounting positions of the respective heat bolts 30 are actually adjusted (rotated) and the mounting positions P1 to P40 change toward the adjustment direction, the heat bolts are adjusted in accordance with the change. The adjustment amounts h1 to h40 change (decrease).

  The display data creation device 205 combines the heat bolt adjustment amounts h1 to h40, the thickness target value O, and the thickness distribution PR together as display data H, and displays the display data H on the display device 206.

  FIG. 2 is a display example of the display data H on the display device 206, FIG. 2 (a) is a display example immediately before the start of adjustment, and FIG. 2 (b) is a display example when adjustment is completed.

  The transmitter 207 transmits the display data H as a radio signal.

  A terminal display device 300 that is a portable device includes a receiver 301 and a display device 302. The receiver 300 receives the display data H, and the display device 302 displays the received display data H. The display screen on the display device 302 is the same as the display on the display device 206.

  As shown in FIG. 2 (a), the display device 206 or the display device 302 has the number of the heat bolt 30 to be adjusted (for example, No7, No8, No9) and the No7, No8, No9. The heat bolt adjustment amount (bolt rotation amount) h of the heat bolt 30 is displayed by, for example, “numbers 5, 8, 5” and “open arrows corresponding to the lengths of 5, 5, 8”.

  If the heat bolt adjustment amount is right rotation (positive rotation), the heat bolt adjustment amount is displayed as a positive numerical value such as “number 5, 8, 5” and the arrow is displayed as a downward arrow, If the adjustment amount is counterclockwise rotation (negative rotation), the heat bolt adjustment amount is displayed as a negative numerical value such as “numbers −5, −8, −5” and the arrow is displayed as an upward arrow.

The operator looks at the display data displayed on the display devices 206 and 302, and heats the No. 7, No. 8, and No. 9 heat bolts 30 manually, 5 turns to the right, 8 turns to the right, and to the right. 5 turns.
With such rough adjustment, the thickness distribution PR becomes flat.

In this way, when the No. 7, No. 8 and No. 9 heat bolts 30 are rotated 5 times to the right, 8 times to the right and 5 times to the right, their mounting positions P7, P8 and P9 also change. The mounting positions P7, P8, and P9 that change and are detected by the heat bolt position sensor 401 are sent to the adjustment amount conversion device 204 via the transmitter 402 and the receiver 201.
For this reason, the adjustment amount conversion device 204 can detect that the rotation of the attachment positions P7, P8, and P9 has been completed five times to the right, eight times to the right, and five times to the right.

As described above, when the heat bolt 30 to be adjusted (for example, No7, No8, No9 heat bolt) is adjusted (rotated), the heat bolt adjustment amounts h1 to h40 gradually become smaller with the rotation, and the display device. In the display of 206 and 302, the heat bolt bolt adjustment amount gradually decreases and the length of the white arrow decreases.
When the adjustment is completed, as shown in FIG. 2B, the number of the heat bolt 30 to be adjusted (for example, No7, No8, No9) is displayed, but the heat bolt adjustment amount (bolt rotation amount) is a numerical value 0. Is displayed, and the white arrow disappears.

  Thus, since the number (No) of the heat bolt 30 to be adjusted and the amount of rotation thereof are displayed on the display device 206 or the display device 302, the operator can work by looking at the display data. Even an inexperienced operator can perform the rough adjustment of the heat bolt 30 accurately and quickly by performing the work as indicated.

That is, when the guidance device 200 is installed near the die 3, the heat bolt 30 can be roughly adjusted by visually recognizing the display image of the display device 206 of the guidance device 200.
Further, when the guidance device 200 is installed in the cab away from the die 3, the terminal display device 30, which is a portable device, is carried, and the display image of the display device 302 is visually recognized, so Adjustments can be made.

  As the terminal display device 300, an HMD (Head Mounted Display) can be adopted.

  Also, the number (No) and adjustment amount of the heat bolt 30 to be adjusted as voice data are sent from the guidance device 200 to the portable terminal device, and the number (No) and adjustment amount of the heat bolt 30 to be adjusted are sent to the portable terminal device. Audio output may be performed.

  In the above embodiment, data is transmitted wirelessly, but may be transmitted by wire.
