Description

Detailed Description of the Invention [Industrial Application Field 1] The present invention relates to a fabric spreading machine that can automatically feed out a fabric from a roll-shaped fabric supported by a fabric support mechanism and prepare it for spreading. This invention relates to an automatic cloth setting device.

I. Prior Art] Fabric spreading is performed by sequentially feeding out the fabric onto a spreading table while running a fabric spreading machine back and forth.

Prior to performing such spreading, it is necessary to perform a fabric setting operation in which the fabric is fed out from the original fabric loaded on the fabric spreading machine and arranged in a predetermined path. Conventionally, such setting work has often been performed manually.

[Problems to be Solved by the Invention] However, there is a problem in that it is cumbersome for one worker to cent the wide cloth, and requires a great deal of labor and time.

The present invention has been made in view of the above-mentioned circumstances, and is capable of automatically performing the work of setting a fabric by unwinding the fabric from a raw fabric mounted on a fabric spreading machine and arranging it in a predetermined path. The purpose of the present invention is to provide an automatic cloth setting device for a reversing machine.

[Means for solving the problem 1 The automatic cloth setting device for the cloth spreading machine according to the first invention is as follows:
A web support mechanism that unwinds the fabric from the original fabric by rotating an unwinding roll that supports the unwinding roll, and a sensor that detects the hanging end of the fabric unwound by the unwinding roll and stops the rotation of the unwinding roll. , a fabric pull-out mechanism having a guide rail extending diagonally upward across the hanging path of the fabric from the fabric support mechanism, the fabric pull-out mechanism including a first roll, and a fabric pull-out mechanism that moves the first roll along the hanging path. A drive means for moving the guide rail two times in the longitudinal direction across the guide rail; A second roll that is movable in two directions, and a rotation that applies rotation to the second roll when the second roll is pushed in the longitudinal direction of the guide rail by the first roll and reaches the end of its movement. means.

An automatic fabric setting device for a fabric spreading machine according to the second invention;
The first roll and the second roll are configured to be able to rotate only in a direction that applies a downward feeding force to the fabric hanging from the fabric support mechanism.

[Operation 1] In this configuration, when the unraveling roll of the original fabric support mechanism rotates and the fabric is unwound from the original fabric, and the hanging end of the fabric is detected by the sensor, the detection command signal causes the unraveling to take place. The rotation of the roll stops and the feeding of the cloth ends.

Thereafter, when the first roll is moved from the movement start point to the movement end point by the driving means of the cloth feeding mechanism, in the initial movement stage of the first roll, the first roll is suspended from the cloth support mechanism. The cloth is caught by the roller and pressed against the second roll waiting at the start of the movement, and the cloth is held between the first roll and the second roll. In the next movement stage of the first roll, as the first roll moves, the second roll moves.
The roll is backed by the first roll, and the first roll and the second roll move in the longitudinal direction of the guide rail of the fabric pull-out mechanism while holding the fabric, and pull out the fabric from the original fabric. When the second roll backed by the first roll reaches the end of its movement, rotation is applied to the second roll by the rotation applying means, and the rotation of the second roll at this time causes the first roll and the second roll to be rotated. A feeding force is applied to the cloth held between the two, and the cloth is fed out to a predetermined position.

When the first roll and the second roll are configured to be rotatable only in a direction that applies a downward feeding force to the fabric hanging from the fabric support mechanism, the first roll and the second roll sandwich the fabric. When the cloth is pulled out by moving in the longitudinal direction of the guide rail, the first roll and the second roll do not reverse and roll against the cloth, and the cloth can be pulled out reliably. be exposed.

(Effects of the Invention) According to the present invention, there is an effect that it is possible to automatically cent the fabric prior to spreading.

Therefore, it is now possible to omit the cumbersome manual fabric setting work that requires a great deal of effort and time.
This is useful in promoting automation of spreading.

Further, the first roll 4 and the second roll 6 are configured to be able to freely rotate only in the direction that applies a downward feeding force to the fabric 101 hanging down from the fabric support mechanism 1, and are prevented from rotating in the opposite direction. It has become. Mechanisms that allow the first roll 4 and the second roll 6 to rotate in only one direction are well known, but for example, such a mechanism can be created by employing a one-way clutch or a ratchet mechanism. can be easily configured. The driving means 5 includes wheel bodies 52 and 53 provided near the lower end and the upper end of the guide rail 51, respectively, and wheels 52 and 53 of the guide rail 51.

The position of the second roll 6 when it is in contact with the second roll 6 is the moving end 6a of the second roll 6. A rotary disk 71 constituting the rotation imparting means 7 is provided concentrically with the wheel body 53 on the other side. This rotary disk 71 is independently rotatable independently of the wheel body 53, and plays the role of regulating the movement end portion 6b of the second roll 6 that has risen along the guide rail 51 by hitting the second roll 6. It has the role of imparting rotational force to the roll 6. Note that the rotary disk 71 is rotationally driven by a motor (not shown).

Next, the effect will be explained.

The automatic setting process of the fabric 101 includes an initial feeding process of the fabric 101 by the fabric support mechanism 1, a drawing process of the fed fabric 101 by the fabric pull-out mechanism 3, and rotation imparting means 7, the first roll 4, and the second roll. 6 and the final feeding step of the drawn out cloth 101.

The initial feeding process is performed as follows.

As shown in FIG. 1, the raw fabric 100, which is a roll-shaped fabric 101, is mounted on the unraveling rolls 11 and 12 so as to straddle the original fabric 100, so that the original fabric 100 is supported by the original fabric support mechanism 1, and then the unraveling is performed. When the roll lL12 is rotated in the direction of arrow a, the raw fabric 100 rotates in the direction of arrow C, and the fabric 10 is transferred from the raw fabric 100 to the fabric 10.
1 is fed out and hangs below the fabric support mechanism 1 (at this time, the hanging path of the fabric Th101 is located between the first roll 4 and the second roll 6, so the hanging fabric 101 passes between the first roll 4 and the second roll 6 and gradually extends downward.
When the hanging end 101a of 01 reaches the sensor 2 as shown by the solid line A, this is detected by the sensor 2, and the command signal from the sensor 2 causes the unraveling roll 11
2 is stopped, and the feeding of the cloth 101 is completed.

The withdrawal process is performed as follows.

After the feeding of the anti-Th1Q1 is completed, the rotational drive device 55
When driven, the rotational transmission mechanism 56! Therefore, the ring body 52
Rotation is transmitted to the cable body 54 of the driving means 5, and at the same time the wheel body 53 rotates, and the first roll 4 is guided by the guide rail 51 as shown by the arrow d and is moved diagonally from its moving end 4a. move upwards. In the first stage of the movement, the first roll 4 catches the fabric 101 L hanging from the fabric support mechanism I and presses the fabric against the second roll 6 waiting at the moving end 6a. As shown, the cloth 101 is held between the first roll 4 and the second roll 6. At the next stage of movement of the first roll 4, as the first roll l moves, the second roll 6 is pushed back by the first roll 4, and the first roll 4 and the second roll 6 sandwich the fabric 101. The cloth drawer mechanism 3 moves in the longitudinal direction of the cloth drawer mechanism 3 in the direction of the arrow d'' without being guided by the guide rail 51. Accordingly, the fabric 101 is pulled out from the original fabric 100 accordingly. This ends the withdrawal process. In this drawing process, the unraveling rolls 11, 12 may rotate freely or may be rotationally driven at a rotational speed synchronized with the drawing speed.

The final feeding process is performed as follows.

The second roll 6 is pushed back by the first roll 4 as described above, and the second roll 6 hits the rotary disk 71 of the rotation imparting means 7 and reaches the end of its movement 6b. When the rotation applying means 7 is rotating in this state, the rotation is transmitted to the second roll 6, and the second roll 6 rotates for a predetermined time or a predetermined number of rotations, and the first roll 4 and A feeding force is applied to the fabric 101 held between the two rolls 6, and the fabric 101 is fed out. At this time,
Rotation is applied to the first roll 4 from the second roll 6 via the cloth 101. As described above, the final feeding process is temporarily completed, but in this embodiment, measures are taken to eliminate wrinkles that may occur in the fabric 101 due to the action of the feeding roll unit 8.

That is, until the cloth 101 is disposed along a predetermined path through the above-mentioned initial feeding process, drawing process, and final feeding process, the feeding roll unit 8 is fed out in front of the feeding roll 81 as shown in FIG. Rolls 82 are arranged, and these delivery rolls 8I, 82 are rotated in the directions of arrows e and f in the figure until the final delivery process is completed. Therefore, the cloth 101 that has completed the final feeding process is
At the end of the process, the fabric 101 hits the front side pay-out roll 81 as shown by the imaginary line C, but after hitting the feed-out roll 81, the cloth 101 is rotated by the feed-out roll 81.
, and is transferred between both feed rolls 81 and 82. In this way, the cloth 101 is transferred to both feed rolls 8182.
The fabric 101 held between the first roll 4 and the second roll 6 continues to be fed, and the fabric 1
01 is fed out, and when it is fed out to a predetermined position, the rotation of the rotary disk 71 of the rotation imparting means 7 is stopped. When the cloth 101 is thus fed out to a predetermined position as shown by the imaginary line 2, the feeding roll unit 8 is rotated 180 degrees as shown by the arrow g in FIG. 2, as shown in FIG. After this,
As shown in the figure, the first roll 4 and the second roll 6 move to their movement start portions 4a, 6a and return to their original positions, whereby the fabric 101 is wound around the feed roll 8L82 in a meandering manner. Here, if the feed roll 82 is provided with a wrinkle smoothing function, the wrinkles generated in the fabric @:1101 are stretched and prepared for spreading. Note that when the first roll 4 is moved in the return direction by the driving means 5, the second roll 6 is accordingly moved in the return direction by its own weight.

In the above, if the first roll 4 and the second roll 6 are configured to be rotatable only in the direction that applies a downward feeding force to the fabric 101 hanging from the fabric support mechanism 1, the first roll 4 and the second roll 6 When the second roll 6 moves in the longitudinal direction of the fabric pull-out mechanism 3 and pulls out the fabric 101 while holding the fabric 101 between them, the first roll 4 and the second roll 6 are reversed, and the rolls 4 and 6 are removed from the fabric. A situation where the cloth 101 rolls against the cloth 101 does not occur, and the cloth 101 is reliably drawn out.

In addition, in FIG. 1 and FIG. 2, 10 is a support plate that supports the fabric 101 during spreading.

In the above, a case has been described in which a middle-face raw fabric is automatically set with the front side facing inside and the fabric is wound into a roll. However, the rolling machine can also set the fabric with the front side facing outside.

That is, this spreader is provided with a conveyor-type fabric feed mechanism 9 below the fabric support mechanism 1 . This fabric feed mechanism 9 moves the fabric 101 hanging down below the first unraveling roll 11 of the fabric support mechanism 1 to the moving ends 4a, 6a.
It is responsible for feeding and hanging between the first roll 4 and second roll 6 that are waiting at the stage. Therefore, after the outer fabric is supported by the fabric support mechanism 1, the first unraveling roll 11 and the second unraveling roll 12 are rotated in the directions of the arrows a'' and a+force to move the fabric 101 as shown in FIG. The initial feeding process is carried out by feeding out the fabric 101 as shown by the imaginary line E and placing it on the fabric feeding mechanism 9, and then sending the fabric 101 between the first roll 4 and the second roll 6 and letting it hang down. Incidentally, the drawing process and the final feeding process of the outer surface original fabric are performed in the same procedure as described above.
