Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a fabric heat bonding machine, and in particular, the tension of an endless belt can be freely adjusted to prevent wrinkles from being squeezed by a pressure roller according to the type of fabric. Regarding a fabric heat bonding machine that can remove.

(Prior Art) Conventionally, when bonding a plurality of fabrics (for example, an outer fabric and a lining fabric), a fabric thermal bonding machine has generally been used. This fabric thermal bonding machine laminates the fabric between a pair of endless belts running vertically facing each other, and heats the endless belt with a heater such as a surface heater while using a pressure roller together with the endless belt. The structure is such that the fabrics are pressurized and the plurality of fabrics are bonded under heat and pressure.

However, when pressurizing fabric with an endless belt using a pressure roller, the endless belt deforms little due to pressure, whereas the fabric is compressed in the thickness direction and tends to expand in the area direction. As shown in Figure 10, depending on the type of fabric, the surface of the fabric may become wavy, creating a gap between the endless belt and the fabric, and the fabric may develop wrinkles due to the pressure applied in this state. There was a point.

Therefore, in view of these problems, the 8th
This is a fabric thermal bonding machine equipped with a tension roller as shown in FIGS. This fabric heat bonding machine is equipped with a tension roller just in front of the pressure roller, and by changing the spindle of this tension roller stepwise up and down or left and right, in other words, the support that receives the spindle of the tension roller is By making holes in stages in the frame of the fabric heat bonding machine and changing the position of the spindle as appropriate depending on the type of fabric, the tension of the endless belt can be adjusted in stages and applied with a pressure roller. The purpose is to stretch the fabric before it is pressed, remove looseness on the surface of the fabric, and then pressurize it to prevent wrinkles from forming in the fabric.

(Problems to be Solved by the Invention) By the way, the degree of occurrence of the above-mentioned squeeze wrinkles differs depending on the type of fabric. For example, 100% wool
In the case of 100% polyester fabric, squeezing wrinkles do not occur much, but in the case of 100% cotton fabric or fabric made of a blend of 65% polyester and 35% cotton, the degree of squeezing wrinkles does not occur much. Although it is difficult to occur in the case of non-woven fabrics, it is easy to occur in the case of woven interlinings. In this way, the degree of wrinkles generated by the pressure roller varies depending on the type and thickness of the fabric to be bonded. Therefore,
In order to remove these squeeze wrinkles using the aforementioned tension roller, it is necessary to finely adjust the tension of the endless belt depending on the type of fabric.

However, with conventional fabric heat bonding machines, the spindle of the tension roller can only be changed in steps up and down or left and right, that is, the tension of the endless belt can only be changed in steps. The problem remains that the tension cannot be finely adjusted accordingly, and therefore, the squeeze wrinkles caused by the pressure roller cannot be completely removed. Furthermore, in order to change the position of the tension roller's spindle, it is necessary to remove the tension roller from the frame and then attach it to another support hole, which is a complicated process, which poses a problem in terms of work efficiency. It was left behind.

Furthermore, even if improvements were made to allow fine adjustment of the position of the tension roller's spindle, the tension roller would be housed within the frame, and the position of the tension roller, that is, the degree of tension on the endless belt, would not be visible from the outside. Another problem is that it is difficult to know and therefore difficult to adjust the position of the tension roller depending on the type of fabric.

The present invention has been made in view of the above circumstances, and its purpose is to easily and quickly freely adjust the position of the tension roller to easily and finely adjust the tension of the endless belt. To provide a fabric pressure bonding machine capable of removing wrinkles caused by a pressure roller depending on the type of fabric.

(Means for Solving the Problems) In order to solve the above problems, the means taken by the present invention are described with reference numerals used in the drawings corresponding to the embodiments. A pair of endless belts (1
0) A fabric heat bonding machine (2) which laminates a plurality of fabrics (S) between the layers, heats them with a heater (20), and pressurizes them with a pressure roller (30) to bond the fabrics (S) together. 1
00), a tension roller (40) provided immediately before being pressed by the pressure roller (30), a drive unit (50) that freely moves this tension roller (40) up and down, and the tension roller ( A table that detects the amount of vertical movement of the tension roller (40) and displays the position of the tension roller (40).
A fabric heat bonding machine characterized by having a receiving part (60) and the following.

In other words, the tension roller (40) located immediately in front of the pressure roller (30) is moved up and down by the drive unit (50), the amount of vertical movement is detected, and the position of the tension roller (40) is displayed. The screen is configured to be displayed by the section (60). In addition, the "two-down movement of the tension roller (40)" in the present invention refers to the case where the tension roller (40) moves vertically in a straight line as shown in FIGS. ) moves up and down in an arc, or moves obliquely toward and away from the pressure roller (30).

(Action of the Invention) The present invention works as follows by adopting the means described in 1.

That is, as shown in FIGS. 1 to 3, a pressure roller (30
), and a tension roller (40) is provided immediately before the
By allowing the tension roller (40) to move downward by 1" by the drive unit (50), the tension of the endless belt (10) can be freely finely adjusted. Therefore, regardless of the type of fabric (S), it is possible to Before being pressed by the pressure roller (30), the fabric (S
) can be stretched to prevent bagging on the surface of the fabric (S). In addition, tension rollers (4
0) is moved downward by the drive unit (50), so the tension roller (40) is moved by the frame (90) as in the conventional case.
This eliminates the need for the complicated work of attaching and detaching. Furthermore, the amount of vertical movement of the tension roller (40) is detected and the position of the tension roller (40) is displayed on the display section (60). It is possible to know the position of the tension roller (40), that is, the degree of tension of the endless belt (10), and therefore, while checking this display, the tension roller (40) is moved by the drive unit (50).
By moving the tension roller (40) up and down, it is possible to move the tension roller (40) to an optimal position depending on the type of fabric (S).

The display on the display section (60) may be either an analog display or a digital display. In the case of a digital display, the downward movement of the tension roller (40) is a fine stepping motion, that is, a fine stepping motion. It may be possible to move up and down in stages.

Next, let's consider the action of the tension roller (40) a little more. As shown in Fig. 4, the position of this tension roller (40) should be as close as possible to the distance (L) from the pressure roller (30) by +j, in order to remove the squeeze wrinkles that occur on the fabric (S). becomes higher. The reason for this is that the pressure applied to the endless belt (10) by the pressure roller (30) becomes smaller as it moves toward the tension roller (40). This is because the pressure applied to the pressure roller (30) or the tension roller (40) becomes smaller toward the front. In other words,
The pressure from the pressure roller (30) gradually decreases, and the pressure from the tension roller (30) gradually decreases as well.
40) - The distance N1° ( I7), the looseness of the fabric (S) stretched by the tension roller (40) will not occur again until the fabric (S) is moved to the pressure roller (30). This increases the degree of removal. From this point of view, in order to remove the squeeze wrinkles caused by the pressure roller (30), the tension roller (40) should be fixed instead of moving up and down, and conversely, the pressure roller (30) should be moved up and down.
The same effect can be obtained even if the above-mentioned distance (L) is arranged to be small.

(Example) Next, an example of the fabric heat bonding machine (100) according to the present invention will be described.

The fabric heat bonding machine (100) according to this embodiment is shown in FIGS.
As shown in Fig. 3, the endless bells 1-(10), -

Endless belt (10), heater (20) and pressure roller (
30) is formed almost in the same way as a conventional fabric heat bonding machine (100), and the endless belt (10) is made by joining aramid fibers impregnated with fluororesin to improve heat resistance in a ring shape. These are arranged vertically facing each other, and a pair of pressure rollers (3
0) etc., it is possible to run at a constant speed. Also, the heater (20) is connected to this endless belt (1
0) A plurality of fabrics (S) laminated between them are heated together with the endless belt (10), and a pressure roller (30) applies a predetermined pressure to the heated endless belt (10) and fabrics (S). The laminated fabrics (S) are heated and compressed by pressing. Note that the heat-pressed fabric (S) is transported outward by a conveyor belt (80).

Next, the tension roller (40) is attached to the auxiliary roller (70).
) and the pressure roller (30), that is, the pressure roller (3
0), and is rotatably supported on the support shaft (41), and the support shaft (41) and the reinforcing vibe (
42) and a rotation shaft (43).
), it is rotatably provided from the frame (90). Therefore, in this tension roller (40), when the roller receiver (44) rotates via the rotation shaft (43), its support shaft (41) moves up and down in an arc.
The tension of the endless belt (10) is adjusted.

The drive unit (50) includes a motor (51) fixed outside the frame (90), a chain (52) and a gear (53) that transmit the rotational force of the motor (51), and a gear (53).

It is composed of a connecting rod (58) whose length is adjustable. Therefore, this drive unit (50) rotates the motor (51) by operating a switch (62) provided on the display unit (60), which will be described later.
51) is transmitted through the gear (53), chain (52), worm gear (54), worm wheel (55), link piece (57), and connecting rod (58) to the roller receiver (44). Rotate the tension roller (40
) is moved upward, or by reversing the rotation of the motor (51) by operating a switch (62), the tension roller (40) is moved downward.

The display section (60) detects the amount of rotation of the worm wheel (55) by means of a link member (64) provided eccentrically on the worm wheel (55) of the drive section (50), and detects the amount of rotation of the worm wheel (55) based on the amount of rotation. A detector (63) consisting of a variable resistor detects the amount of vertical movement of the tension roller (40), and a resistance value of the detector (63) detects the amount of vertical movement of the tension roller (40).
) and a display device (61) consisting of a 7-segment LED that displays the position of the point. Therefore, this display (
60) detects the amount of vertical movement of the tension roller (40) by operating the switch (62) with a detector (63), and displays the position of the tension roller (40) which is hidden by the frame (90) and is not visible. By (61), numbers from 0 to 9 are displayed. In the case of this embodiment, a stopper (not shown) is provided to prevent the tension roller (40) from moving up and down more than necessary, and the indicator (61) also displays numbers from 1 to 5. It is supposed to be done. Note that this display (61) may be an analog display such as a bar display.

Now, the fabric thermal bonding machine (100) according to the present embodiment configured as described above operates as follows. First, the endless belt (10) and the fabric (S) heated by the heater (20) are lifted by the tension roller (40) before being pressed by the pressure roller (30), and their tension causes the fabric to The looseness that occurs in the fabric (S) is removed, and the fabric (S) is prevented from drawing wrinkles when it is pressed by the pressure roller (30).

At this time, the tension roller (40)
), and the amount of vertical movement can be displayed on the display unit (60), so that the numbers (1 to 5) displayed on the display unit (61) of the display unit (60) ) while operating the switch (62), the position of the tension roller (40), that is, the tension of the endless belt (10) can be finely adjusted. Therefore, if you check in advance the optimal position of the tension roller (40) that can remove squeeze wrinkles depending on the type of fabric (S), you can avoid cases where the type of fabric (S) to be bonded needs to be changed frequently. Even if the pressure roller (30
) can remove the drawing wrinkles.
