Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a fixed-sized surface material in which an opaque hard base material, such as a metal plate, is molded to have a concave cross section, and a male connecting portion and a female connecting portion are formed on both side walls. Then, a composite material formed integrally with the heat insulating material continuously filled in the concave shape and a sheet-like backing material that continuously covers the back side of the heat insulating material is heated while traveling according to the length of the surface material. This invention relates to a sizing cutting device.

BACKGROUND ART Conventionally, there have been many devices that cut a band-shaped hard sheet material into a fixed size while traveling.

Most of these sheet materials are single members,
In addition, as the feed roller rotates, a rotating transducer connected to the roller generates pulses, and when the number of pulses for the length set as the cutting length matches the number of pulses from the transducer, an output signal is output and the cutter is cut. One drive was used to cut the sheet material to a fixed size.

However, in a composite material with a sandwich-inch structure as shown in FIG. After that, the continuous band-shaped composite material formed by filling the heat insulating material 3 in a concave shape and then laminating the back material 4 is set to the specified dimensions of the surface material, for example, 3636 mm to 13030 mm,
242,411Lr/L, it was difficult to cut while driving.

That is, if the roller is flat and made of a single material, such as a metal plate, and the hard member can be reliably held between the rollers, no errors will occur in the rotation of the rollers.

However, when a composite material consisting of a heat insulating material such as a synthetic resin foam and a sheet-like backing material is held between rollers and the length is measured, the board thickness becomes uneven and it cannot be held very tightly, causing slippage. This results in a large error between the measured length and the actual length.

In particular, since the surface material has already been cut to a fixed size, the width of the slit between the edges of the surface material is often about 0.5 to 5 mm, and this uneven slit width (length) can be cut with a roller. This is because it cannot be measured reliably.

In order to eliminate such drawbacks, the present invention has developed a slit in the connecting part of a long strip of material, which is made by connecting a number of surface materials cut to a fixed size in series with tape, etc., using photoelectric, magnetic, ultrasonic, etc. After precisely detecting the cutting position of the long composite plate using the signal, the cutter is driven to cut the composite material (surface material connection tape, heat insulating material, etc.) along the length of the surface material. This paper proposes a fixed-size cutting device for cutting back material.

In the figure, reference numeral 1 denotes a continuous band-shaped composite material, which has a concave cross-section, has a female connecting portion 1a and a female connecting portion 1b at the upper ends of its left and right side walls, and is made of an opaque hard material as described above. The surface material 2 is cut into small pieces, and the surface material 2 is filled, for example, in the recessed portion and the back surface of the female connecting portion, and the surface material 2,
and a heat insulating material 3 made of a synthetic resin foam that adheres the following heat insulating material 3 and back material 4 together with self-adhesive properties during foaming, and a continuous sheet-like back material 4 that covers the back surface of the heat insulating material 3. It is composed of

5 is a pressure roller consisting of upper and lower rollers 5 a and 5 b, which feeds a continuous band-shaped composite material in the direction of the arrow;
This prevents displacement and shaking of the composite material while driving.

6 is a cutter consisting of a rotary blade, a shear, etc., which cuts the composite material 1 to the length of the surface material 2 while the composite material 1 is traveling, synchronized with the speed thereof, and in a clamped state;
Reference numeral 7 denotes a cart which moves a cutter 6 to the composite material 1 in response to a signal to be described later on guide rails 8 arranged on both sides of the composite material 1 in the traveling direction.
This process repeatedly synchronizes the speed of the object and returns to the original position.

Numeral 9 is a clamp that clamps both the composite material 1 and the truck 7 when the positions of the composite material 1 and the truck 7 are determined and the speed of the truck T synchronizes with the speed of the composite material 1.

Note that the clamp 9 is reset immediately after the cutter 6 cuts the composite material 1.

10 is a slit detector that detects the slit between the connecting parts of the surface material 2 in the composite material 1, especially the slit formed between the insertion edges 1a in the composite material 1 having the shape as shown in the figure, and
This is to detect the speed of the composite material 1.

To explain further, as shown in FIG.
1, a speed detection roller 12 and a detection unit 13 arranged on the lower side.
and a support collar 14.

Further, the roller 12 is supported on both sides of the support collar 14 via bearings 15, and a rotation transducer (not shown) for measuring the number of rotations is mounted on one side of the roller 12.
was planted.

Further, the support collar 14 is fixed to one end of the fixed shaft 16,
The middle part thereof is made convex, and a shaft part 14a into which the bearing 15 is fitted is formed on the left and right sides of the shaft part 14a, and the detection part 13 is fixed to a part of the convex part of the support collar 14, and its lead wire 1T is led out. A through hole 14b is provided for this purpose.

The detection unit 13 consists of a detection element 13a, a protection main body 13b, and a protective cover 13C provided as necessary.
As a, one of light, electricity, magnetism, and ultrasonic waves is used.

Further, the fixed shaft 16 supports the free roller 18 and conveys the composite material 1, and if necessary, a through hole 16a is bored in the axial center of one end of the fixed shaft 16 to transmit the signal from the lead 1T to the outside of the shaft. It is useful for deriving

Note that a rubber plate can also be used as the protective cover 13C when an ultrasonic transducer is used.

19 is an amplifier, and 20 is a reference signal oscillation circuit, which continuously oscillates a constant signal.

Reference numeral 21 denotes a signal comparator which compares the reference signal and the signal from the detector 10, and outputs the signal to a computer to be described later only when the signal differs from the reference signal.

22 is a position detector for detecting the distance from the cross section of the composite material 1 to the cutter 6; 23 is a computer that detects the running speed signal from the roller 12, the signal from the signal comparator 21, and the position This is for calculating the movement and driving timing of the cutter 6 from the signal from the detector 22, and sending a signal to the controller 24 to control the operation of the cutter 6 and the carriage γ based on the calculated signal.

Reference numeral 25 is used to sandwich the fixed-sized composite plate 1 obtained by cutting the composite material 1 with a fast-feeding roller between upper and lower rollers 25a and 25b, to feed it to the next process, and to detect its speed.

A speed comparison circuit 26 compares the speed signal from the roller 12 and the speed signal from the fast feed roller 25, and controls the rotation of the fast feed roller 25 via the speed controller 2γ.

Reference numeral 28 is an auxiliary roller, and 29 is a belt conveyor for transporting the composite plate 1 coming out of the rapid feed roller 25 to the next process.

Next, the operation will be explained.

In FIG. 2, it is assumed that the tip of the band-shaped composite material 1 as described above has arrived at the slit detector 10 via the pressure roller 5 from a molding machine (not shown).

Until then, only the signals from the signal comparator 21 and the position detector 22 of the trolley T have been supplied to the calculator 23, and no signals from the roller 12 have been received, so the cutter 6 and the fast-feeding roller 25 have not operated. It's stopped.

However, when the composite material 1 enters the slit detector 101, a speed signal is sent from the roller 12 to the calculator 23.

On the other hand, since the same signal as the reference signal is inputted to the signal comparator 21 from the detection element 13a, the output becomes zero.

When the slit between the insertion edge 1a of the surface material 2 passes, a transmission signal and a detector 10 as shown in FIG.
The received signal from the slit corresponds as shown in the opening of FIG. 4, but when the slit passes as shown in FIG. 4, the received signal disappears.

As a result, a signal is output from the signal comparator 21 to the computer 23 since the first diagram is different from the second diagram.

Based on this signal, the computer 23 outputs the cutter 6, the carriage γ,
And an operation signal is sent to the fast feed roller 25.

Each of them is moved and driven according to the signal, and the composite material 1 is cut into two lengths of the surface material while traveling.

This cut composite plate 1 is transferred to the next process via a rapid feed roller 25.

The fast-feeding roller 25 is set at a speed approximately twice as fast as the pressing roller 5 in order to prevent collisions between the cut composite plates 1 of a certain size.

Therefore, in order to cut the composite material 1 into two lengths of the surface material, the above-described operations may be repeated.

What has been described above is only one embodiment of the present invention, and FIG.
As shown in the enlarged view, the roller 12 of the slit detector 10
be covered with a rubber plate 30, or the slit detector 10 may be covered with a rubber plate 30.
For example, a photoelectric element, electricity, magnetism, etc. may be used as the ultrasonic detection element.

In this case, the rubber plate 13G in FIG. 3 is replaced with glass, the pressing roller 11 is made of a translucent material, and at least some photoelectric elements 31 are mounted on the inner wall of the rubber plate 13G as shown in FIG. A lead wire 32 and a main shaft 33 are connected so that the width of the device goes around the inner circumferential surface once, and a lead wire 32 that collects signals from the device is connected to the main shaft 33.
It is also possible to output the signal to the signal comparator 20 via the signal comparator 20.

Of course, although not shown, the slit detector 10 can also be provided at the center of the composite material 1 (at the center of the fixed shaft 16).

Note that a photoelectric element system cannot be used as the detection element 13a at this time.

Furthermore, although not shown, it is also possible to construct a slit detector in which a speed detection roller is attached to the other end of the fixed shaft 16, and only the slit detector 10 is installed at one end.

As described above, according to the sizing cutting device according to the present invention, the cross section is concave, and the insertion edge serving as the male type connecting portion is provided at the lower end of one side wall, and the engagement groove serving as the female type connecting portion is provided at the lower end of the other side. It has an extension part whose lower edge is extended outward, and the surface material is made by cutting a hard base material to a fixed size, and only the concave part is connected in series with adhesive tape in the direction of travel, and on top of that, unfoamed It is characterized by the ability to discharge a synthetic resin foam raw material, then laminate a continuous sheet-like backing material, and accurately cut the integrated composite material to the length of the facing material.

In addition, the speed of the composite material, the position of the trolley, and the position of the cutter are mutually detected and controlled to drive and stop each part, so there is no mistake in the cutting position.
