Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates primarily to a device for releasing the opening of a woven fabric roll, etc., which is suitable for use in a tying machine for unraveling and sewing woven fabric rolls.

Prior Art When fabric is subjected to processing such as bleaching, dyeing, coating, etc., the fabric (hereinafter referred to as woven fabric roll) woven by a loom and wound into a roll is processed as it is.
Since it is uneconomical to make them into processing units, the ends of several dozen woven fabric rolls are sewn together and connected to a predetermined large processing unit. The machine used for this process is already known under the name of a tying machine (for example, Japanese Patent Publication No. 50-18117 and Japanese Patent Publication No. 52-50318).

The problem to be solved by the invention is that these prior art tying machines simply require a woven fabric roll supply device for feeding woven fabric rolls, and a winding start end of two woven fabric rolls. It is necessary to connect a sewing machine device for sewing the end of the roll and a discharge device for storing the long cloth sewn by the sewing machine device in a folded state. The process of pulling out the final winding end of the cloth from the woven cloth roll and supplying the pulled out end to the sewing machine has still been performed manually.

Generally speaking, in conventional tying machines, after the suturing is completed,
Since the fabric roll being released was simply placed on rolling rollers arranged in packets,
The stability of the woven fabric on the rolling rollers was not sufficient, and the problem that the woven fabric roll could not be wound smoothly was unavoidable, especially when the woven fabric roll was deformed.

On the other hand, there is a similar problem when unwinding not only cloth but also other film-like materials, sheet-like materials, etc., and a solution to this problem is strongly desired in these industries as well.

Therefore, in view of the actual state of the prior art, it is an object of the present invention to automatically pull out the winding end from a woven fabric roll, etc.
This can be supplied to a sewing machine device, etc., and at the same time,
An object of the present invention is to provide a novel opening release device for a woven fabric roll, etc., which can realize smooth winding of a woven fabric roll.

Means for Solving the Problems The structure of the present invention to achieve the object is to provide a feed roller and a bucket roller, the former being interlocked with a small diameter roller and a large diameter roller juxtaposed with a small gap. The small-diameter roller can swing in an arc around the large-diameter roller, while the latter can support a fabric roll, etc. between both rollers. The gist is that a plurality of rolling rollers are disposed around the circumference, excluding the opening for introducing the material, and that the roller is rotatable by accommodating a fabric roll or the like.

In the case of the above structure, after supporting the fabric roll etc. on the feed roller, the feed roller is reversely rotated, the outer shape of the fabric roll etc. is adjusted, and then it is rotated in the normal direction. The end of the woven fabric roll, etc. can be automatically pulled out onto the large-diameter roller, while the woven fabric roll, etc. can be ejected from the pick-up roller by swinging the small-diameter roller around the large-diameter roller. Then, the bucket roller is slightly rotated in the normal direction, and then it is formed from the woven fabric roll, etc. By pulling out the woven fabric roll, etc., the position at which it is pulled out from the woven fabric roll, etc. is located on the side of the woven fabric roll, etc. At the same time, the woven fabric roll etc. is freely on the rolling roller of the bucket roller,
Moreover, since it can rotate stably, it is possible to realize a smooth unwinding operation of a woven fabric roll or the like.

Example Examples will be described below with reference to the drawings.

A device for releasing a woven fabric roll, etc., includes a picking roller 10 consisting of a small diameter roller 11 and a large diameter roller 12, and a bucket roller 30 including a plurality of rolling rollers 31, 31, . . .
(Figure 1). However, this embodiment shows an example in which the present invention is incorporated into a tying machine for unraveling and stitching a woven fabric roll R.

The small-diameter roller 11 and the large-diameter roller 12 forming the feed roller 10 are pivoted in parallel to each other on a common bracket 14 and are interlocked by a chain 13. The bracket 14 is swingable around the shaft 12a of the large-diameter roller 12, and is provided with an air cylinder 14a to determine its swinging position. Also,
Between each peripheral surface of the small diameter roller 11 and the large diameter roller 12,
A small gap d@ is provided (FIG. 2), and an upward air nozzle 15 is disposed toward this small gap d.

The bucket roller 30 is disposed adjacent to the feed roller 10 (Fig. 1), and its basic components include a plurality of rollers whose ends are rotatably supported on disks 31a, 31a at both ends. The moving rollers 31, 31... (Fig. 3).

The rolling rollers 31, 31... are arranged on the circumference,
Although it forms a cage shape as a whole, rolling rollers 31 are not disposed on a part of its circumference, and an opening 31b is provided.
(range indicated by the two-dot chain line in FIG. 1).

The bucket roller 30 as a whole consists of bearings 3 that are pivotally supported at the ends of two swinging arms 32, 32... on the left and right sides.
1d and 31d (Fig. 3), and the shaft 31
A sprocket 33C is fitted to G, and a chain 33
It is connected to the deceleration motor 33a via b. Here, the deceleration motor 33a is installed on a bracket 33d protruding from the bearing 31d. Also, how to use bearing 3'
A bracket 34b is vertically installed on the ld, and a ball screw shaft 36 with a universal joint 36a is driven by a swing motor 34a installed on the bracket 34b.

Further, the ball screw shaft 36 is screwed into a ball screw bearing 35 fixed to a fixed bracket 35a, and a series of members including the swing motor 34a, the ball screw shaft 36, and the ball screw bearing 35a are connected to the bucket roller 30. It forms a shaft swinging device for tilting.

On the upstream side of the feed roller 10, there are provided a belt conveyor C for horizontally conveying the woven fabric roll R, a stopper C1 for positioning the woven fabric roll R at the end of the belt conveyor C, and a woven fabric roll R. A chain conveyor VC for upward conveyance is provided (FIG. 1). The chain conveyor VC is provided with a carrier vC1 for carrying the woven fabric rolls R one by one.
This carrier ■C1 is tilted with one end touching the dog VC2 provided near the upper end of the chain conveyor VC, so that the fabric roll R rolls from the carrier VC1 onto the feed roller 10 and the small diameter roller 11. It is designed to be transferred to an intermediate position between the large-diameter roller 12 (first
(double-dashed line in the figure).

On the other hand, a sewing machine M is installed below the feed roller 10 and the bucket roller 30, while behind the bucket roller 30 there are idler rollers TR1, TR2 and a drive roller TR3 in contact with the idler roller TR2. A take-up roller TR is provided, and a swing device eSW and a storage box SB are arranged roughly below the take-up roller TR, and these devices are sewn together by a sewing machine M. The cloth RC pulled out from the cloth roll R housed in the bucket roller 30 is pulled out, folded, and stored.

The operation of the opening release device for the fabric roll or the like in the cloth tying machine having such a configuration is as follows.

First, the rod of the air cylinder 14a is shortened and the bearing 1
4 in the direction opposite to 14 in the direction of the arrow in FIG. At the same time, the bucket roller 30
By operating the deceleration motor 33a, the rotation angle is set so that the opening 31b is diagonally upwardly inclined toward the feed roller 10 side, and the device is on standby.

The chain conveyor VC conveys one of the fabric rolls R conveyed on the belt conveyor C upward, and then transfers it to the intermediate recess formed by the small diameter roller 11 and the large diameter roller 12. do.

Here, the winding direction of the cloth RC wound around the cloth roll R is as follows: When the large diameter roller 12 is rotated in the direction of arrow 12 in FIG. This is the direction in which the cloth RC is unwound.

A woven fabric roll R is placed between the small diameter roller 11 and the large diameter roller 12.
Once it is supported, first, the large diameter roller 12 is driven in the opposite direction of the arrow 12 by a motor (not shown). As a result, the small diameter roller 11 also
3 in the same direction, the fabric roll R is rotated in the opposite direction of the arrow KR by both rollers 11.12. At this time, the rotating direction of the Hffi roll R is opposite to the direction in which the 15RC forming the woven fabric roll R is unwound.
It is possible to remove the wrinkles existing on the woven fabric roll R by tightly winding it on the woven fabric roll R, and at the same time to arrange the end of the roll, which is to become the drawer pane of the fabric RC, into the correct shape.

Next, the large diameter roller 12 is driven in the direction of arrow 12. Since the rotation direction of the fabric roll R at this time is the direction of the arrow KR, the fabric Rc is thereby unwound. Therefore, if the small gap d between the large diameter roller 12 and the small diameter roller 11 is sufficiently small, the drawn end of the cloth Rc will be drawn out along the circumferential surface of the large diameter roller 12.
In addition, if air is ejected from the air nozzle 15 toward the small gap d, there is no risk that the pulled end of the cloth RC will fall into the small gap d, and therefore, the unwound @RC will surely be , can extend over the circumference of the large-diameter roller 12 and hang down between the large-diameter roller 12 and the bucket roller 30 for a long time.

When the pulled end of the cloth RC is fully unwound to reach the sewing machine device M, the drive of the large diameter roller 12 is stopped and the air cylinder 14a is extended, thereby removing the bracket on which the small diameter roller 11 is attached. 14 is the large diameter roller 1
Since the small-diameter roller 11 swings around the shaft 12a of 2 in the direction of the arrow 14, the small-diameter roller 11 swings around the large-diameter roller 12 in an arc shape. As a result, the small diameter roller 1
1 pushes up the woven fabric roll R, so the woven fabric roll R is
It is moved along the circumferential surface of the large-diameter roller 12, slides off the large-diameter roller 12 in an R-shaped manner, is ejected from the feed roller 10, and is fed into the bucket roller 30 through the opening 31b.

On the other hand, since the winding end of the fabric RCO of the preceding woven fabric roll R reaches the sewing machine device M by hanging down from the idler roller TR1 of the take-up roller TR, the sewing machine device M Both ends of the cloths RC and RCO are sewn together by a mechanism not shown, and the cloths RC and RC are sewn together along the suture line m.
Connect O.

Therefore, in parallel with the stitching process of the fabrics RC and RCO by the sewing machine M, or at the end of the process, the bucket roller 30 is rotated about 1/4 turn in the direction of the arrow 30.
Since the opening 31b is located diagonally above and on the opposite side to the feed roller 10, the position at which the cloth RC is pulled out from the woven fabric roll R stored in the bucket roller 30 is the same as that of the woven fabric roll R. The drawing direction is guided by the rolling roller 31 forming the end opposite to the arrow 30 of the opening 31b, and the drawing direction is directed upward in a substantially vertical direction (as shown by the solid line in FIG. 1). ).In such a state, if the pull-out roller TR is driven in the direction of the arrow KTR, the cloth RC,
The RCO is gradually pulled upward (double-dashed line in FIG. 1), and finally the cloth RC unwound from the fabric roll R in the bucket roller 30
0 (solid line in FIG. 1). Therefore, when continuing the operation of the take-up roller TR, the woven fabric roll R
are the rolling rollers 31, 31... of the bucket roller 30.
While rolling on top, it is continuously unwound, and at this time,
The cloth RC that has passed through the take-up roller TR is transferred to the swing device S.
It hangs downward while swinging back and forth by W, and can be stored in the storage box SB in a folded state.

Housed in the bucket roller 30, rolling roller 31.31
...The woven fabric roll R that is being unwound while rolling on top is in a closed space surrounded by the fabric RC being pulled out from it and the rolling rollers 31, 31... All the rolling directions are the rolling rollers 31.31
Since the fabric roll R is closed by...
In the process of unwinding, there is no risk of the roll accidentally deviating from the bucket roller 30 and falling off. This is particularly important when the woven fabric roll R is a coreless roll and has been significantly deformed from its correct cylindrical shape. According to this bucket roller 30, the woven fabric roll R is extremely flat Even if it is a roll, it can be unwound smoothly enough and the unwinding operation can be carried out.

When all the fabric RC from the woven fabric roll R housed in the bucket roller 30 to the winding start end has been rewound, generally the woven fabric roll R is formed in the bucket roller 30. The core tube used during this process is left behind. Therefore, the core tube can be discharged downward by rotating the roller 30 of the bucket 1 about 1/4 turn in the direction of arrow 30 in FIG. 1 so that the opening 31b is located at the lowest position. can.

Thereafter, the take-up roller TR is reversed and stopped until the winding start end of the woven fabric roll R reaches a length sufficient to reach the sewing machine, while the bucket roller 30 is roughly rotated about 1/2 turn to close the opening. 31b to the initial standby position,
Thereafter, the same process may be repeated.

In addition, when the woven fabric roll R is a so-called coreless roll and no core tube remains at the end, there is no need to pass through the core tube discharge position, so the bucket roller 30 completes the winding. At the same time, it can also be rotated in the opposite direction to the direction of arrow 30 and returned to the standby position. Further, even if the core pipe is passed through the discharge position, it is not necessarily necessary to temporarily stop the rotation of the bucket roller 30 at the position, and the speed is low enough for the core pipe to fall. As long as it is, it is sufficient to pass through it in continuous rotation.

On the other hand, in the process of unwinding the fabric roll R accommodated in the bucket roller 30 as described above, if a difference in tension occurs in the width direction of the fabric RC, the fabric roll R is Therefore, the traveling position of the cloth RC on the take-up roller TR also moves accordingly. Therefore, the running position of the cloth RC on the take-up roller TR is detected,
By driving the swing motor 34a attached to the bucket roller 30 in a predetermined direction based on this signal, it is possible to correct the difference in tension in the width direction generated in the cloth Rc. That is, by rotating the pole screw shaft 36, the swing motor 34a can move the bucket roller 30 in the axial direction. If the bucket roller 30 is moved in the direction shown in FIG. 4, the left swinging arm 32 approaches the vertical direction and the right swinging arm 32 moves away from the vertical direction. , are tilted so that the right side is higher (FIG. 2(A)). Therefore, the bucket roller 30
The inner woven fabric roll R gradually moves to the left due to gravity while rolling within the bucket roller 30, so this direction causes the movement of the running position of the fabric RC on the take-up roller TR. By determining the position signal of the cloth Rc on the take-up roller TR and the rotation direction of the swing motor 34a so as to correct the difference in tension in the width direction of the cloth RC, this can be corrected. can be corrected, and a beautiful folded shape can always be obtained in the storage box SB. When tilting the bucket roller 30 in the opposite direction, the swing motor 34a may be driven in the opposite direction to move the bucket roller 30 to the right ((B) in the same figure).

The above explanation is based on the following explanation: (5) A weaving process in which RC is wound into a roll; Although an example in which the counter-dyed material to be unrolled has been described above, the counter-dyed material to be unrolled is not limited to the woven fabric roll R, but various sheet-like materials, film-like materials, etc., can be wound into rolls. Needless to say, it can be used in exactly the same way when unwinding.

As described in the detailed description of the invention, according to the invention,
A lead roller consisting of a small-diameter roller and a large-diameter roller arranged side by side with a small gap is provided so that the small-diameter roller can swing in an arc shape around the large-diameter roller,
A bucket roller is provided, which has a plurality of rolling rollers arranged around the circumference, excluding the opening for introducing the woven fabric roll, etc., and can rotate while accommodating the woven fabric roll, etc. By rotating the feed roller supporting the fabric roll, etc. once in the reverse direction, and then rotating it in the forward direction, the drawer end can be pulled out after correcting any irregularities such as wrinkles that exist on the fabric roll, etc., thereby speeding up the drawing process. Not only can it be easily automated, but after the small-diameter roller is oscillated and the woven fabric roll, etc. is fed into the bucket roller, the bucket roller is rotated approximately 1/4 turn, and then the woven fabric roll, etc. is wound. By doing this, the woven fabric rolls, etc. in the bucket roller are pulled out to the side, and the rolling direction of the woven fabric rolls, etc. due to the drawer is completely closed by the rolling rollers. Therefore, there is no risk of the woven fabric roll, etc. accidentally falling off the bucket roller, and therefore, even if the woven fabric roll, etc. is deformed, the smoothness of the winding process can be effectively eliminated. It has the excellent effect of being able to eliminate
