Abstract

PURPOSE:To obviate the refixing of a catcher each time in case of performing varied cloth extension by constructing the machine in such a way that the catcher moves on a cloth extending board integrally with a cloth extending machine main body when the cloth extending machine main body moves longitudinally on the cloth extending board. CONSTITUTION:The subject cloth extending machine is provided with a raw cloth holding mechanism 21 and a raw cloth delivery mechanism for delivering cloth from a raw cloth roll C1 held at the raw cloth holding mechanism. The raw cloth delivery mechanism is formed of a cloth releasing mechanism 27, a delivery belt 18 and a delivery roll 19. The end part of the delivered cloth is held by the holding member 52 of a catcher 3. The holding member 52 moves longitudinally in front of a cloth extending machine main body by the driving mechanism. The catcher is integral with the cloth extending machine main body and moves on a cloth extending board 2. In case of block cloth extension or extending cloth again in a different position on the cloth extending board, there is no need to refix the catcher, thereby improving the efficiency remarkably.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fabric spreading machine for feeding out a fabric onto a fabric spreading table.

[Conventional technology]

The spreading work involves moving the main body of the spreading machine, which is mounted on a spreading table so that it can move back and forth, from its forward position to its retreat position, and unwinding the fabric from the roll held in the spreading machine. On the other hand, it is the work of spreading the fabric on a spreading table. At the start of the spreading, the end portion of the fabric fed out from the main body of the spreading machine onto the spreading table is held in place by the catcher's holding tool. In a spreading machine that performs such a spreading operation, the catcher is used to prevent the fabric from slipping on the spreading table during spreading, thereby ensuring stable spreading.

In conventional spreading machines, the main body of the spreading machine is mounted on a spreading table, and the catcher is attached to the spreading table.

On the other hand, in normal fabric spreading, a plurality of fabrics are stacked at the same position by repeatedly moving the fabric spreading machine body back and forth. and,
For such stacked spreading, there are two methods: one method using one place on the spreading table, and one method using multiple places on the spreading table (
It is called block spreading.

) etc. are being carried out.

[Problem to be solved by the invention]

However, when performing block spreading with a conventional spreading machine, it is troublesome to remove the catcher from the spreading table and attach it to the new spreading position every time the spreading position on the spreading table changes. This reduced the productivity of block spreading.

Even when spreading the fabric using one location on the spreading table, the spreading position is not always the same, and in that case, the troublesome attachment of the catcher needs to be fixed.

The present invention has been made in view of the above circumstances, and by equipping the main body of the spreading machine with a catcher, it is possible to carry out block spreading or to perform new spreading at a different position on the spreading table. An object of the present invention is to provide a spreading machine that does not require attaching and repairing a catcher each time.

[Means to solve the problem]

The fabric spreading machine of the present invention includes a fabric spreading machine main body having a fabric holding mechanism that holds a fabric roll, a fabric feeding mechanism that feeds out the fabric from the fabric roll held by the fabric holding mechanism, and It is equipped with a clamping tool that clamps the end of the fabric fed out from the mechanism, and a catcher that has a drive mechanism that moves the clamping tool back and forth in front of the main body of the spreading machine, and the catcher is attached to the main body of the spreading machine. It is characterized by being

[For production]

According to the spreading machine having the above configuration, when the main body of the spreading machine is moved back and forth on the spreading table, the catcher moves together with the main body of the spreading machine on the spreading table.

〔Example〕

FIG. 1 shows a spreading machine according to an embodiment of the present invention. In the figure, reference numeral 1 denotes the main body of the fabric spreading machine, which is comprised of a traveling unit 100 and a fabric feeding unit 1-200.

In the traveling unit 100, the traveling wheels 12 of the trolley 11 are connected to the spreading table 2.
It is mounted on a rail and is prevented from coming off by a guide wheel 14. In addition, the output of the motor 15 is
6 and the chain transmission mechanism 17 to the running wheels 12. Further, the cart 11 is equipped with a feeding belt 18 and a feeding roll 19 for guiding the feeding of the fabric C, which will be described later.
A control panel 20 for setting control values for automatic spreading work is installed on the side plate of No. 1.

The fabric feeding unit 200 includes a fabric holding mechanism 21 that holds a fabric roll C. This original fabric holding mechanism 2
1 is a pair of front and rear rolls 22.23 and the unit l-20
The guide groove 25 is formed in the left and right side plates 24 of 0 and extends in the vertical direction.

Then, the rod R inserted through the paper tube of the original fabric roll C1 is fitted into the guide groove 25, and the original fabric roll CI is placed on the pair of rolls 22, 23. Reference numeral 26 denotes an original fabric roll delivery mechanism for placing the original fabric roll C4 on the predetermined position shown in the figure. In addition, the cloth feeding unit 20
The front part of 0 is equipped with a release mechanism 27. The unraveling mechanism 27 includes an unraveling roll 30 connected to a rotating shaft 28 of a motor via a transmission mechanism 29, and a pair of front and rear clamping rolls 31 and 32 provided corresponding to the unraveling roll 30. However, the unraveling roll 30 has a relatively large diameter and has a non-slip surface, and the clamping rolls 31 and 32 serve to press the cloth C against the unraveling roll 30. This unraveling mechanism 27, the feeding belt 18 of the traveling unit 100, and the feeding roll constitute a fabric feeding mechanism.

3 is the catcher. As shown in FIGS. 2 and 3, the catcher 3 has a pair of left and right arms 41, 42,
A movable body 43.44 attached to these arms 41.42 so as to be movable back and forth, a shaft body 45 horizontally suspended rotatably between these movable bodies 43.44, and a movable body 45 equipped on the shaft body 45. A plurality of claw pieces 46... and those claw pieces 46...
It has a fixed piece 47 disposed on the shaft body 45, a motor 48 that applies rotational force to the shaft body 45, and a timing belt 50 that is rotated by the motor 49 in the forward and reverse directions. When the motor 49 is driven to rotate in the forward or reverse direction, the rotation is transmitted to the movable bodies 43.44 via the timing belt 50, and the rotation is transmitted to the movable bodies 43.44 through the timing belt 50.
44, a shaft body 45 having a claw piece 46, and a fixed piece 47
It is designed to move back and forth within the setting range of the stroke S shown in the figure. Therefore, the motor 49 and the timing belt 50 constitute a drive mechanism 51 for the catcher 3. Further, the claw piece 46 and the fixing piece 47 constitute a clamping tool 52. Moreover, the structure is such that the forward and backward movement is smoothly guided by the action of the guide grooves 53 formed in the movable bodies 43 and 44 and the arms 41 and 42.

As shown in Fig. 1, this catcher 3 is attached to the spreader main body 1 so as to protrude from the front end of the spreader main body 1, and as the spreader main body 1 moves back and forth, the catcher 3 also moves back and forth. Move to.

Reference numeral 4 denotes a cutting mechanism, which is attached to the boundary between the catcher 3 and the spreader main body 1.

In the above, when the unraveling roll 30 is rotated as shown by the arrow a in FIG. Then, the fabric C is unrolled one after another from the fabric roll C1. At this time, the pair of rolls 22 and 23 supporting the raw fabric roll C5 are rotationally driven in the direction of feeding out the fabric C in synchronization with the feeding speed, but these rolls 22 and 23 do not necessarily have to be driven. For example, it may be configured to rotate following the feeding of the cloth C. In this way, when the cloth C is pulled out from the raw roll CI by the unwinding roll 30, a situation in which the raw roll C1 loosens and wrinkles occur in the cloth C can be effectively prevented. can.

The fabric C pulled out by the unraveling roll 30 is transferred to the feeding belt 1
The sheet is fed out to the front of the main body 1 of the paper spreading machine 1 by a feeding mechanism including a feeding roll 8 and a feeding roll 19. At this time, when the claw piece 46 of the clamping tool 52 is lowered onto the spreading table 2 as shown by the imaginary line in FIG.
2 slides on the spreading table 2 and is scooped up by the claw piece 46 as shown by the imaginary line in the figure. Therefore, at that point,
When the motor 48 is driven and the claw piece 46 is pulled up as shown by the arrow, the end C2 of the cloth C is held between the claw piece 46 and the fixed piece 47. Also, from this state, the motor 48
When it is stopped, the claw piece 46 descends as shown by arrow d, releases the end C2 of the cloth C, and the end C2 is placed on the cloth spreading table 2.

Next, an example of the spreading work using the above-mentioned spreading machine is shown in Fig. 5a~
This will be explained with reference to FIG. 5h.

After determining the spreading position on the spreading table 2 and bringing the clamping tool 52 of the catcher 3 close to the spreading machine body 1 as shown by the arrow e in Fig. 5a, the unraveling roll 30 is rotated as shown in Fig. 5b. Then, unroll the cloth C from the raw roll C+, unwrap it, and unwind the cloth C.
The end C1 of is held by the clamping tool 52. Unraveling roll 30
The action of feeding out the cloth C and the action of holding the end Ct of the cloth C by the clamping tool 52 are as described above.

Thereafter, while continuing to feed out the fabric C, move the clamping tool 52 away from the fabric spreading machine main body 1 as shown by arrow r in FIG. to open. Then, as shown in Fig. 5d, move the clamping tool 52 further away from the spreader main body 1 to release the end C2 of the cloth C onto the spreader table 2! ! place When the fabric C is placed over a certain length on the spreading table 2 in this way, depending on the type of fabric of the fabric C, if the fabric is relatively thick, the weight of the fabric C and the spreading table 2, the fabric C becomes difficult to slip on the spreading table 2, and even if the fabric C is separated from the clamping tool 52, the fabric C will not slip during the spreading operation due to the movement of the fabric spreading machine body 1, which will be described later. A situation such as movement on the spreading table 2 does not occur.

Next, as shown in Figures 5e to 5f, the spreading machine body 1 is moved at a preset distance (for example, 4 m) as shown by arrow g.
, and spread the fabric C on the spreading table 2. At this time, the claw piece 46 of the clamping tool 52 is pulled up as shown by the solid line in FIG.

Then, when the main body of the spreading machine 1 reaches the retreated position, the cutting mechanism 4 is operated to cut the fabric C as shown in Fig. 5g. Next, the parts of the main body 1 of the spreading machine 1 except for the trolley 11 are raised by a predetermined amount to prepare for the next spreading operation, and the main body 1 of the spreading machine 1 is moved forward as shown by arrow i in Fig. 5h to the forward position. After that, the clamping tool 52 is brought close to the spreading machine main body 1 as indicated by the arrow e in FIG. 5a.

Thereafter, the same operations as described above are repeated a predetermined number of times to stack and spread the fabric. Further, after stacking and spreading the fabric at a predetermined position on the fabric spreading table 2, the fabric spreading machine main body 1 and the catcher 3 are moved backward or forward to perform the stacking and spreading at another position without removing the stacked and spread fabrics. It is also possible to perform stacking and stretching. This is so-called block spreading. Furthermore, after removing the previously stacked and stretched fabrics, it is also possible to spread the fabrics at a different position in the same way.

〔Effect of the invention〕

According to the present invention, there is no need to reattach the catcher each time when performing block spreading or when newly spreading the material at a different position on the spreading table, which eliminates the need for troublesome catchers.
Since the fixing work can be omitted, the productivity of block spreading can be greatly improved compared to the conventional method.
