Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a spreading machine for automatically unwinding a piece of cloth onto a spreading table and cutting it into a predetermined length for stacking or folding. Regarding

[Conventional technology]

The spreading method is to stack a number of pieces of cloth cut into a certain length so that the front or back surface is facing up, while folding and folding the pieces of cloth to meander without cutting. Therefore, in the past, dedicated spreading machines have been used for one-way spreading and folded-back spreading, respectively.

FIG. 7 exemplifies a conventional spreading machine dedicated to one-way spreading, and as the spreading machine body 2 moves backward on the spreading table 1, the spreading machine body 2 moves away from the spreading machine body 2. The piece W of material that has been unwound onto the spreading table 1 is cut by a traverse type cutter 3 provided at the bottom of the spreading machine body 2, and then the spreading machine body 2 moves forward and returns again. When the cloth moves, the cloth W is stacked on the cloth W that has already been spread. In such a spreading machine, the feeding start end portion of the cut cloth W is not held at all and is simply placed on the spreading table 1, so that it is cut by the cutter 3. Often, the feeding end portion W ₁ of the piece of material is misaligned with respect to the end portion of the piece of material that has already been extended, and in such a case, the operator manually adjusts the position to stack the material in order. .

FIG. 8 exemplifies a conventional spreading machine dedicated to folding and spreading, in which a catcher 4 is provided at the front end of the spreading table 1 and a pitcher 5 corresponding to the catcher 4 is provided with a spreading machine main body 2 It is provided in. The catcher 4 is the main body 2
The starting point of the folded back of the piece of cloth W that has been fed out from the stretch table 1 to
It has a function of pinching W ₂ in cooperation with the stretch base 1, and is a swing bar that is swingably supported between a position on the stretch base 1 and a position lifted from the stretch base 1. With 4a.
The pitcher 5 is arranged so that the pitcher 5 is in sliding contact with the spreading table 1 and the spreading machine main body 2
And a pair of left and right inclined legs 5a, 5 which are provided in the lower part of the catching machine and scoop up the pushing bar 4a of the catcher 4 to lift it up from the spreading table when the spreading machine body 2 moves to the forward end.
have a. A cutting bar 6 is provided between the left and right inclined legs 5a, 5a in the vicinity thereof. The cutting bar 6 is suspended from the lower part of the reciprocating machine body 2 so as to be swingable back and forth. Further, the push bar 7 is provided at the rear of the cutting bar 6.
Is provided. Therefore, when the retraction machine main body 2 reaches the forward end, the cutting bar 6 rides on the pressing bar 4a and is released, and under the pressing bar 4a scooped up by the inclined legs 5a, 5a. The folding start end W _{2 of the} piece of cloth is pushed in by the pushing bar 7. The cloth spreading machine the main body 2 begins to backward push bar 4a is inclined legs 5a, is edge cutting from 5a is folded leading end W ₂ of fabric attached sandwiched by the cloth spreading plate 1 and the pressing bar 4a.

[Problems to be solved by the device]

As described above, conventionally, it has been necessary to perform one-sided spreading and folded-back spreading with dedicated spreading machines, respectively, so that the spreading machine has poor versatility and is uneconomical. In some cases, the versatility was improved by making the blasting machine main body 2 common and replacing the cutter 3, the pitcher 5 and the catcher 4 as attachments. Therefore, it takes time to perform the preparatory work for shifting to the spreading work, and the productivity is reduced.

Therefore, it is considered that if a cutter is attached to the spreading machine for folding and unfolding described with reference to FIG. 8, it is possible to perform one-way spreading together with the folding and unfolding, but conventionally, the cutter is the one of the spreading machine of FIG. As described above, it is supposed to be attached to the lower portion of the main body 2 of the spreading machine, and moreover, since the pitcher 5, the cutting bar 6 and the pushing bar 7 are already attached to the lower part of the main body 2 of the spreading machine, there is a space for mounting the cutter. Hard to secure.

By the way, in Japanese Utility Model Publication No. 59-29005, a catcher is provided on the side of the spreading table and a pitcher is provided at the lower part of the main body of the spreading machine, and a cutter is attached in front of the pitcher at the bottom of the spreading machine body. When cutting the feeding end portion of the above, the cutter is made to traverse in front of the pitcher. In a spreading machine configured such that the cutter attached to the lower part of the spreading machine body is made to traverse in front of the pitcher, the cutter catches the catcher when the spreading machine body moves forward and approaches the catcher. The cutter must be released to the side so that it does not interfere with the.

However, in such a case, it is necessary to secure a retracting space for the cutter on the front side of the retraction machine, and the retraction machine body reciprocates at high speed simply by securing such a retreat space. It is dangerous because the cutter sometimes reciprocates together with the main body of the spreading machine at a position protruding to the side of the spreading table. Therefore, it is necessary to secure the retreat space for the gutter and at the same time widen the width of the reciprocating table by at least the retreat space to ensure safety.

Therefore, in the spreading machine described in the above publication, the spreading table has to be widened by the retracted space of the cutter,
This has the disadvantage of increasing the space required for the installation of the fabric-spreading machine, and is expensive.

The present invention has been made in view of such circumstances, and it is possible not only to carry out folding and one-sided spreading without exchanging attachments, but also the drawbacks of the spreading machine described in the above publication. That is, an object of the present invention is to provide a fabric spreading machine that does not have the drawbacks that the space required for installing the fabric spreading machine is wide and the cost is high.

[Means for Solving the Problems]

The inventor of the first invention extends an incinerator body that is reciprocally moved back and forth on an incinerator base and an infeed start end portion of the piece of material that is unwound from the incinerator body onto the incinerator table. The catcher includes a catcher that cooperates with the table to squeeze, a cutter that traverses and cuts the feeding end portion of the piece of material that is unwound from the incinerator body onto the inferior table, and a pitcher that corresponds to the catcher. Is installed at the front end of the spreading table corresponding to the forward end of the spreading machine body, and can be swung between the position on the spreading table and the position raised from the spreading table. The pitcher is provided on the lower part of the retraction machine main body so as to be in sliding contact with the retraction table, and the catcher is provided when the retraction machine main body moves to the forward end. The cutter has an inclined leg that scoops up the pressure bar of the Those attached to the cloth spreading machine body at a position above the catcher and the pitcher.

The spreading machine of the second invention is the spreading machine of the first invention,
A cloth cutting bar is hung on the lower part of the main body of the cloth spreading machine so that it can swing back and forth, and at the position between the cutting bar and the cutter, the cloth cutting bar is moved forward and backward between the front and the rear of the hanging path of the cloth. A bar is provided on the main body of the cloth spreader, and this movable bar is a piece of cloth that protrudes slightly forward of the drooping path when the main body of the cloth spreader has returned to a position near its return end. Tensioning, and projecting the feeding end portion of the piece of cloth cut by the cutter to the receivable first position,
After receiving the feeding end portion of the piece of cloth at the first position, it is projected to the second position in front of the first position, and the feeding end portion is folded over the cutting bar in the middle of the projecting step. It is configured.

[Action]

According to the first and second inventions, by appropriately selecting whether to operate the cutter or the movable bar,
Not only can it be used separately for one-sided spreading and one for folded-back spreading, but when performing one-sided spreading, the feeding start end of the piece of material that has been fed to the spreading table can be spread by the catcher. Even if the cutter is attached to the middle part of the retraction machine main body, that is, the position above the pitcher, the feeding end part of the cut piece of cloth is always in a fixed position. Stacked. In addition, the cutter is attached to the main body of the retraction machine at a position above the catcher, so no matter where the cutter is stopped, the cutter will catch the catcher when it moves forward and approaches the catcher. Will not interfere with. As a result, it is not necessary to secure a retreat space for the cutter on the side of the retraction machine body, and it is not necessary to expand the width of the retraction table by the retreat space. Especially the second
According to the invention, when the movable bar is projected to the first position, the piece of cloth is tense, so that stable cutting can be performed by the cutter, and when the movable bar is projected to the second position, the end of feeding the piece of cloth is cut. Since it hangs over the bar in a folded shape, by the subsequent return movement of the spreading machine main body,
The cutting bar reliably spreads the feeding end.

[Embodiment] FIG. 1 is a schematic perspective view of a retraction machine according to an embodiment of the present invention. Numeral 10 is the main body of the spreading machine, which is a horizontal spreading table with traveling wheels 11.
It is reciprocated back and forth over 12. The main body 10 of the spreading machine indicates a raw roll (not shown), and a pair of raw roll feeding rolls 1 for feeding a raw material while vibrating the raw roll in small steps.
And a guide roll 14 that hangs down the piece of material fed from the raw material feeding roll 13, a guide bar 16 that guides the traverse of the cutter 15 for cutting, a guide rod 17, a support rod 18, and the descent of piece of material. A movable bar 19 that is moved back and forth between the front and the rear of the path, a pushing bar 20, a cutting bar 21,
And a pitcher 23 having a pair of left and right inclined legs 22 and 22. And, as is clear from the figure, the pitcher 23 is provided at the bottom of the spreader main body 10 and
When reciprocating, the tip ends of the inclined legs 22, 22 are in sliding contact with each other on the reciprocating table 12. Also the cutter
Reference numeral 15 is attached to the upper part of the rebeling machine main body 10, that is, at a position above the pitcher 23, and a guide rod 17 and a support rod 18 are provided between the cutter 15 and the pitcher 23. The movable bar 19 is adapted to move in and out just below the support rod 18. Further, the attachment position of the cutter 15 is above the catcher 25 described below.

Reference numeral 25 is a catcher, which is arranged at the front end of the spreading table 12 corresponding to the forward end of the spreading machine main body 10, and the base ends of the arms 27, 27 provided at both ends of the pressing bar 26. Are swingably supported by brackets 28, 28 which are erected on the extension table 12.

FIG. 2 exemplifies a mechanism for moving the movable bar 19 in and out. In this example, a rack 30 is extended on a push-pull rod 29 connected to the end of the movable bar 19 at a right angle. The configuration is such that 30 is engaged with pinion 31. 32 is a box cover that houses the pinion 31.

Next, the operation of the one-sided spreading will be described with reference to FIGS.

FIG. 3 shows a state in which the cloth spreader main body 10 is moved back to a position in the vicinity of the returning end thereof, and the cutter 15 traverses along the guide bar 16 so that the cloth W is cut. At the time of cutting by the cutter 15, the movable bar 19 is stopped at the first position, which is projected slightly forward of the support rod 18, as shown in FIG. As a result, as shown by the broken line in the figure, the feeding end portion W ₁ of the cloth W is bent into a smooth S-shape by the guide bar 16, the guide rod 17, the support rod 18, and the movable bar 19, and becomes a tension state. The cutter 15 has an advantage that stable cutting can be assisted. When the piece of cloth W is cut, its feeding terminal end W ₁ hangs down by its own weight and is received by the movable bar 19.

Thereafter, the movable bar 19 projects further to the second position further forward as shown in FIG. 4 with the main body 10 of the retraction machine stopped. The feeding end portion W ₁ of the cloth W received by the movable bar 19 in the course of this projecting step is folded over the cutting bar 21 as shown in FIG. Movable bar 19 is immediately the first
It is retracted to the rear of the position.

Next, as shown by the arrow in FIG. 5, the retraction machine main body 10 moves backward to reach the return end. In the middle of the return movement at this time, the feeding end portion W _{1 of the} piece of cloth W, which was hung over the cutting bar 21 in a folded shape, is spread by the judgment bar 21 which is moved back together with the retraction machine body 10. As shown in the drawing, the unwound articles W, which have already been unwound, are stacked on the feeding end portion. At this time, since the feeding beginning W ₂ of the fabric W is held on the cloth spreading table 12 by the catcher 25, as described later, the feeding end of the cloth W the feeding end portion W ₁ is being already Nobehan Accurately aligned and stacked on top of the unit. Further, when the retraction machine main body 10 moves backward, the material W is unwound by the unrolled sheet unwinding roll 13, and the unwinding starting end W ₂ thereof is hung down to the vicinity of the unrolling table 12 as shown in FIG.

After this, the retraction machine body 10 starts to move forward. Spreading machine body 10
6 reaches the forward end, the inclined leg 22 of the pitcher 23 hits the projection 26a provided on the pressing bar 26 of the catcher 25 from below as shown in phantom in FIG. Lift off the table 12. Further, the cutting bar 21 swings as shown in the figure and rides on the pressing bar 26, and at the same time, the pressing bar 20 enters under the pressing bar 26. Therefore, the cloth W
The feeding start end W _{2 of} is pushed by the pushing bar 20 under the pushing bar 26. Therefore, when the retraction machine body 10 starts returning from this state, the pushing bar 20 comes out from under the pressing bar 26, and at the time when the inclined leg 22 separates from the projection 26a, the pushing bar 26 feeds the cloth W. It falls on the starting end portion W ₂ , and due to its own weight, the feeding end portion W ₂ is pushed out against the spreading table 12 and is clamped. As a result, the feeding start end portion W ₂ is held on the reciprocating table 12 while being positioned. When the main body 10 of the cloth-spreading machine returns to a position near the return end thereof, the cutter 15 traverses along the guide bar 16 to cut the cloth W, and thereafter, the series of steps described above are continuously repeated. Be done.

The above is the operation when performing the one-sided spreading, but according to this spreading machine, it is also possible to perform the folded-back spreading without exchanging the attachment. That is, when performing folding and spreading, the cutter 15 and the movable bar 19 are paused, and the raw material feeding roll 13 is always rotated when the main body 10 of the spreading machine is moved forward and backward, and the cloth W To continue feeding. By doing this, the continuously fed out piece of material is folded back in a meandering manner on the spreading table 12 by the forward and backward movements of the spreading machine body 10, and the same spreading as that of the spreading machine explained in FIG. Done.

[Effect of device]

As described above, according to the first and second inventions, one-sided spreading can be performed by operating the cutter or the movable bar, and folded back spreading can be performed if the cutter or the movable bar is not operated. Therefore, it becomes possible to efficiently perform all the spreading operations of the one-sided spreading and the folded-back spreading with the common spreading machine without changing the attachment as in the conventional case, and the versatility of the spreading machine is improved. In addition, since the feeding start end of the piece of cloth can be held on the spreading table by the catcher when performing the one-sided spreading, the cutter was cut even if it was attached to the intermediate part of the spreading machine body. There is also an advantage that the end portions of the unwound material feeding are always stacked in a fixed position, and the need for manual position correction is reduced. Furthermore, there is no need to retract the cutter to the side of the fabric spreading machine in order to avoid the cutter from interfering with the catcher when the fabric spreading machine moves forward. There is no disadvantage such as having to secure a retracting space for the cutter on the side and expanding the width of the reciprocating table by the amount of the retracting space.

Further, in particular, according to the second invention, when the movable bar is projected to the first position, the piece is tense, so that stable cutting by the cutter is possible, and the movable bar is the second.
Since the feeding end portion of the piece of cloth is hung over the cutting bar in a folded manner by projecting it to the position, the feeding bar is surely spread by the cutting bar by the subsequent return movement of the main body of the spreading machine.
