Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spreading device, and more particularly to a spreading device used for spreading a cloth (fabric) on a spreading base.

[0002]

2. Description of the Related Art Heretofore, there has been known a reversing device (reversing device traveling type reversing device) in which a reversing machine is installed on a reversing base so as to be able to run back and forth. In this reversing device, while running a reversing machine equipped with a reversing device, the reversing method is to pull out the remnants from the raw material mounted on the reversing device onto the reversing base and extend the remnants. Is performed. In addition, when performing the spreading by using the spreading device, a catcher is installed at a predetermined position of the spreading base, and the catcher holds the end of the unreeled material from the spreading machine to hold the spreading. It has been practiced to increase the positional accuracy of the piece of cloth that has been made.

[0003] On the other hand, there is also known a spreading device in which a catcher is installed on a rolling base so as to be able to travel back and forth (catcher traveling type spreading device). In this rolling device, the raw material is placed on a table placed at a predetermined position on the rolling material base, and the end of the material unreeled from the raw material is held by a catcher, and the catcher is run. Thereby, a cloth reversing method is performed in which the cloth is drawn out from the raw material and the cloth is extended on the reversing base.

[0004]

In the above two types of spreading devices, the reversing machine running type spreading device can be used to extend a piece of material on a spreading base for a long time (hereinafter referred to as "long-length spreading"). ) Is mainly used when a piece of cloth is extended shortly (hereinafter, "short length extension")
Is not often used. This is heavy and large because the reversing machine is equipped with a lifting device, a traveling drive device, and a web, etc., and enhances the high-speed traveling performance of the reversing machine and the stopping position accuracy under high-speed traveling In particular, there are many restrictions that make it difficult to speed up the rolling performance.

[0005] On the other hand, the catcher traveling type spreading device is mainly used for the above-mentioned short spreading, and is not often used for the long spreading. This is because the catcher is lighter and smaller than a reversing machine, and its high-speed running performance and stopping position accuracy under high-speed running are easy to increase, so it is easy to speed up the reversing performance with short length rolling. It depends.

[0006] From the above circumstances, conventionally, a long-length spread using a reversing machine running type spreading device, and a short length spreading using a catcher running-type spreading device, such as using a catcher running type spreading device. In many cases, a reversing machine-type spreading device and a catcher-running type rolling device are properly used depending on the length of the cloth. In addition, in consideration of the properties of the cloth, for example, elasticity, there is a case where the reciprocating apparatus and the catcher traveling apparatus are selectively used.

The present invention has been made in view of the above circumstances, and an extension device capable of performing the extension with high precision in both the case of performing the long extension and the case of performing the short extension. The purpose is to provide.

It is another object of the present invention to provide a spreading device capable of performing spreading at any position in the front-rear direction of the spreading table.

It is a further object of the present invention to provide a spreading device in which the position of a cloth extending to the spreading table can be easily controlled automatically by a computer.

[0010]

The present invention provides a spreading device, a spreading machine, a spreading machine installed on the spreading base so as to be able to run back and forth, and a catcher which is drivable installed back and forth opposite to, and a respective further travel driving mechanism for running back and forth the cloth spreading machine and the catcher individually, in the above-described cloth spreading machine and the catcher, piece goods The fixed teeth can be switched between an operating state in which the end of the cloth is clamped and held and a non-operating state in which the end of the piece is released.

The above movable teeth that are pushed down and pulled up are attached to the lifting frame
And each of the clamps is provided to move up and down, and the reversing machine is provided with an unraveling mechanism for unwinding a cloth from a raw material mounted on the reversing machine.

[0011] According to this spreading device, it is possible to freely select between rolling the rolling machine on the rolling base and rolling the catcher. . That is, it is possible to perform a long spreading by running the reversing machine while stopping the catcher, and perform a short spreading by running the catcher while stopping the reversing machine. Will be possible.

[0012] It is desirable that the spreading device has a servo mechanism for controlling each traveling drive mechanism for individually moving the spreading machine and the catcher back and forth. According to such a reversing device, the servo mechanism helps to accurately control the position of the reversing machine when the reversing machine is running and the reversing is performed, and the servo mechanism is also used when the catcher is running and the reversing is performed. It is useful to control the position of the object with high accuracy. Therefore, the position accuracy of the cloth material extended on the rolling base is improved even when the rolling is performed by running either the reversing machine or the catcher.

In the spreading device of the present invention, the running drive mechanism on the side of the spreading machine for running the spreading machine back and forth includes:
A first timing belt connected to the reversing machine and capable of traveling back and forth, a first timing pulley around which the first timing belt is wound, and a first electric motor for rotating the first timing pulley. A traveling drive mechanism on the catcher side for causing the catcher to travel back and forth is connected to the catcher and capable of traveling back and forth;
It is possible to adopt a configuration including a timing belt, a second timing pulley around which the second timing belt is wound, and a second electric motor for rotating the second timing pulley. According to such a spreading device, the rotation of the rotating shaft of each of the first and second electric motors is accurately transmitted to each timing belt via each timing pulley. Even when the spreading is performed, the positional accuracy of the cloth extended on the spreading base is improved. Further, it is possible to use a servomotor provided with the above servo mechanism as the first electric motor or the second electric motor. Further, since it is not necessary to mount the traveling drive mechanisms on the reversing machine side and the catcher side on the reversing machine and the catcher, it is possible to easily control these traveling drive mechanisms automatically by a computer.

The end 112 of the cloth 110 is released. Thereby, the end 112 of the piece 100 is delivered from the reversing machine 3 to the catcher 5. Here, in each of the clamps 42 and 55, the state in which the movable teeth 45 and 58 are pulled up to form a gap between the movable teeth 45 and 58 and the fixed teeth 43 and 56 is the non-operating state of the clamps 42 and 55. In this state, the end of the cloth is released from the clamps 42 and 55. Also,
In each of the clamps 42 and 55, the state in which the movable teeth 45 and 58 are pushed down and the fixed teeth 43 and 56 hold the end of the cloth is the operating state of the clamps 42 and 55. Are clamped by the clamps 42 and 55.

According to the spreading device described above, the spreading base 1
For running the spreading machine 3 on the surface (rolling machine running type spreading)
And performing the rolling of the catcher 5 (catcher running type rolling) can be freely selected.

In the case of carrying out a rolling type rolling machine, as shown in FIG. 7, for example, a catcher 5 is installed at a predetermined position in the front-rear direction of a rolling base 1, and the rolling machine 3 is moved to the catcher 5. Means of running on the gantry 1 is adopted. In this case, the traveling drive mechanism 9 on the catcher side is stopped.

In this type of rolling machine, the spreading machine 3 on which the raw web 100 is mounted is moved forward to approach the catcher 5 as shown in FIG. The end 112 of the cloth 110 that is held and protrudes in front of the clamp 42 is the clamp 5 of the catcher 5.
Handed over to 5. The end 112 of the cloth 110 at this time
The delivery procedure from the reversing machine 3 to the catcher 5 has been described above.

After the end 112 of the piece 110 is transferred from the reversing machine 3 to the catcher 5 and the clamp 42 of the reversing machine 3 is switched to the non-operating state, the operation of the reversing machine-side traveling drive mechanism 8 causes the operation. The reversing machine 3 travels backward as indicated by an arrow A1 in FIG. At this time, since the end 112 of the cloth 100 is held by the clamp 55 of the catcher 5, when the reversing machine 3 travels backward, the web 100 extends for a length corresponding to the traveling distance of the reversing machine 3. It is pulled out from the reversing machine 3 and extended on the reversing stand 1. At this time, the bucket roll 34 of the disengaging mechanism 33 is driven by the drive motor 34a as necessary. However, if not necessary, the drive motor 34a is stopped to allow the bucket roll 34 to idle. When the reversing machine 3 travels backward by a predetermined distance, the reversing machine-side traveling drive mechanism 8 stops, and the cutter mechanism 48 of the reversing machine 3 operates to cut the fabric 100 at a location near the clamp 42. Thereafter, the clamp 55 of the catcher 5 is deactivated to release the end of the cloth 100 that has been held so far and drop it on the extension base 1. Next, the reversing machine side traveling drive mechanism 8 operates again, the reversing machine 3 travels forward, approaches the catcher 5, and the end 112 of the reversing machine 100 is moved from the reversing machine 3 to the clamp 55 as described above. The same operation is repeated after being passed. When the height of the material pile on the spreading table 1 becomes high, the lifting drive mechanisms 7 and 8 of the spreading machine 3 and the catcher 5 operate to operate the clamps 42 and 5 respectively.
Adjust the height of 5 to a height that is commensurate with the stack height.

In the case of performing the catcher traveling type spreading, for example, as shown in FIG. 8, the spreading machine 3 is installed at a predetermined position in the front-rear direction of the spreading table 1, and the catcher 5 is moved to the spreading machine 3. Means of running on the gantry 1 is adopted. In this case, the traveling drive mechanism 8 of the reversing machine 3 is stopped.

In this catcher traveling type spreader, the catcher 5 travels and approaches the spreader machine 3 on which the raw fabric 100 is mounted as shown in FIG. 8, and at that position, the catcher 5 is held by the clamp 42 in the operating state. The end 112 of the cloth 110 protruding in front of the clamp 42 is the clamp 55 of the catcher 5.
Passed to. The procedure for delivering the end 112 of the cloth 110 from the reversing machine 3 to the catcher 5 at this time has been described above.

After the end 112 of the cloth 110 is transferred from the reversing machine 3 to the catcher 5 and the clamp 42 of the reversing machine 3 is switched to the non-operating state, the catcher-side traveling drive mechanism 9 operates to move the catcher. The vehicle travels forward as indicated by arrow A2 in FIG. At this time, the end 11 of the cloth 100
2 is held by the clamp 55 of the catcher 5, so that when the catcher 5 travels forward, the web 100 mounted on the reversing machine 3 is separated from the reversing machine 3 by a length corresponding to the traveling distance of the catcher 5. It is pulled out and extended on the spreading table 1. At this time, the bucket roll 34 of the disengaging mechanism 33 is driven by the drive motor 34a as necessary. However, if not necessary, the drive motor 34a is stopped to allow the bucket roll 34 to idle. When the catcher 5 travels a predetermined distance forward, the catcher-side traveling drive mechanism 9 stops, and at the same time, the clamp 42 of the reversing machine 3 is activated to hold the end of the piece 100, and in this state, the The cutter mechanism 48 of the machine 3 operates to cut the cloth 100 at a location near the clamp 42. Also,
When the clamp 55 of the catcher 5 is in the inoperative state, the end of the cloth 100 that has been held so far is released and dropped on the spreading base 1. Next, the catcher-side traveling drive mechanism 9 operates again, and accordingly, the catcher 5 travels to move the reversing machine 3.
, The end 112 of the cloth 100 is transferred from the spreading machine 3 to the clamp 55 as described above, and the same operation is repeated. When the height of the material pile on the rolling table 1 is increased, the lifting drive mechanisms 7, 8 of the reversing machine 3 and the catcher 5 are operated, and the heights of the clamps 42, 55 are changed to the height of the material pile. Adjust to a height suitable for

In the above-described spreader running type and catcher running type spreader, the electric motor 85 of the spreader side running drive mechanism 8 and the electric motor 95 of the catcher side running drive mechanism 9 are used.
Has a built-in servo mechanism, so that the traveling distance of the reversing machine 3 and the catcher 5 can be easily and accurately determined. Further, since the reversing machine-side traveling drive mechanism 8 and the catcher-side traveling driving mechanism 9 are not mounted on the reversing machine 3 or the catcher 5, they can be easily controlled automatically by a computer. Further, it is also possible to automatically control all necessary operations such as the timing of delivery of the end of the piece of cloth by a computer. For this reason, the length and position of the cloth extended on the rolling base 1 are accurately determined, and the spreading is performed with high accuracy.

[0031] The above-mentioned rolling machine is preferably used for a rolling machine having a long rolling distance.
It is preferably used for a short spreading distance. The spreading of each of these methods can be performed at any position of the spreading table 1 by changing the initial position of the spreading machine 3 and the initial position of the catcher 5 with respect to the spreading table 1. For example, FIG.
As described above, the catcher 5 is moved to the front side of the cloth 200 that has already been stretched, and the catcher 5 is run at the front side of the cloth 200 to perform the catcher traveling type spreading, or the spreading machine 3 is moved. It is possible to carry out a spreading type running type rolling.

In the present invention, the configurations of the clamps 42 and 55 and the configurations of the lifting and lowering driving mechanisms 6 and 7 may have configurations other than the configurations described in the embodiment.

[0033]

As described above, according to the spreading device of the present invention, a single spreading device can be used instead of using a spreading machine running type catching device and a catcher running type spreading device as in the prior art. Long and short rolls can be performed. Also, since both the reversing machine and the catcher can travel and can be made to travel at any position on the reversing table, the reversing can be performed at any position in the front-rear direction of the reversing table. Become like Furthermore, in the one having a servo mechanism for controlling each traveling drive mechanism for individually moving the reversing machine and the catcher back and forth, the position accuracy of the revolved cloth can be easily increased, and In addition, it becomes possible to automatically control the running of the reversing machine and the catcher by a computer.
