BACKGROUND OF THE INVENTION The present invention relates to a lap forming machine equipped in a ribbon wrapping machine, in which a plurality of wrap fleeces drafted by a drafting device are successively layered while being inverted by a curl plate. Wrap fleece polymerization apparatus.

[0002]

2. Description of the Related Art A conventional wrap forming machine mounted on a ribbon wrapping machine will be described with reference to FIGS. This lap forming machine is composed of a plurality of lap fleece F
(Hereinafter, simply referred to as “fleece”), a plurality of draft devices D for drafting each, and a plurality of fleeces F drafted by each draft device D, a wrap fleece polymerization device A for overlapping and forming a layer. And a lap forming device B for winding the fleece F layered by the polymerization device A 'into a wrap by winding it on a bobbin. In the lap fleece polymerization apparatus A ′, a plurality of (six in the illustrated example) curl plates P _{1 to} P ₆ are arranged above the table 11 at predetermined intervals along the moving direction Q of the fleece F. Configuration. On the upstream side of the lap fleece polymerization apparatus A ', with respect to the direction in which the fleece F flows, a plurality of sets of lap rollers 2 each serving as a one-to-one set for supporting the supply wrap L are provided. The supply wrap L is provided between each of the wrap rollers 2 provided in parallel with the plates P _{1 to} P ₆ and each of the curl plates P _{1 to} P _6.
There are provided draft devices D for drafting the fleece F drawn out of the apparatus.

On the table 11 constituting the lap fleece polymerization apparatus A ', several pairs of feed rollers R, one-to-one, for feeding the fleece F from above and below to the downstream side are provided on the table 11. They are provided at predetermined intervals along the movement direction Q. The feed roller R includes a press roller disposed above and a calender roller disposed below. Also, in this table 11,
A fleece guide 3 is provided to prevent the fleece F from moving laterally when the fleece F moves. The fleece guides 3 are provided facing each other at a predetermined interval (corresponding to the maximum width of the fleece F) along a direction orthogonal to the moving direction Q of the fleece F,
A large number of fleece guides 3 in a one-to-one set are provided at predetermined intervals along the moving direction Q of the fleece F.

[0004] Each fleece F drawn from each supply wrap L supported by a pair of wrap rollers 2 is drafted by a predetermined amount by a drafting device D, after which each fleece F is removed from each of the curl plates P ₁ to P ₁ . the P ₆ is reversed while changed the direction of movement 90 °, fleece F of the upstream side is superposed manner one after the other the lower side, slide into moved over the table 11. In this manner, the fleece F superimposed on a plurality of layers on the table 11
Enters the lap forming apparatus B through the width approach plate 4,
Here, it is wound again on the bobbin and becomes a wrap.

[0005] case of Hajime紡lap-forming machine, or if the fleece F is cut at a portion of the curl plate P ₁ to P ₆ (this case will be described later), the worker is machine base Move the fleece F of each supply wrap L
Through the respective draft devices D arranged downstream and the curl plates P _{1 to} P ₆ on the table 11, and the respective curl plates P _{1 to} P on the table 11.
_The fleece F that has been drawn is stored in the area directly below ₆ . The length of the fleece F stored on the table 11 is based on the position of the stored fleece F, and the length of the fleece F up to the feed roller R located first toward the downstream side. Whichever is shorter, which is the length up to the portion immediately below the curl plate positioned first. Specifically, the curl plates P ₁ . P _2.
P _4. The length of the fleece F to accumulate on the table 11 immediately below the P ₆ are required length from the position to the feed roller R which is located initially toward the downstream side, the curl plate P _3. The length of the fleece F to accumulate in the table 11 immediately below the P _5, it is necessary length to the portion just below the curl plate P _2, and the P ₄ respectively.

Then, the operator holds the fleece F stored on the table 11 by hand, inserts the tip of the fleece F between a pair of upper and lower feed rollers R, and It is gripped by the roller R. On the other hand, when the distance from the position of the fleece F stored on the table 11 to the first curl plate is shorter than the first feed roller R toward the downstream, the downstream The leading end of the fleece F is placed on the table 11 below and slightly upstream of the first curl plate, and the fleece F transferred by the curl plate is placed on the fleece F. It is necessary to prepare so that the fleece F can be superimposed on the table 11. As described above, this lap forming machine has a plurality (six in this embodiment) of supply wraps L, so that the operator has to perform the above-described preparation work by the number of supply wraps L. Also, when the operator holds the fleece F by hand and inserts the tip of the fleece F between the pair of feed rollers R, the operator may accidentally put his / her hand between the pair of feed rollers R and be caught. It was dangerous.

When any of the supply wraps L runs out during the winding of the fleece F by the lap forming machine, the operator stops the machine base and puts the full wrap on the pair of lap rollers 2, This full wrap fleece F is set as the succeeding fleece F and is overlapped with the trailing end of the preceding fleece F. In this case, when the overlapped portion of the fleece F to tandem short, the above-mentioned draft device D, or being clipped seam fleece F in the portion of the curl plate P ₁ to P _6. Further, if the overlapping portion of the fleece F is long, the overlapping portion becomes thicker, so that the overlapping portion can be completely grasped between the top roller and the bottom roller (both not shown) of the draft device D. However, this causes the overlapped portion of the fleece F to be cut. Although the above lap splicing is performed manually, there is a device for automatically performing the lap splicing. This automatic luff splicing device is provided with a suction pipe at a cut end of a full wrap supported by a pair of lap rollers 2. , The cut end is peeled off, and the cut end is superimposed on the rear end of the preceding fleece F. In the case of this apparatus, the length of the overlapping portion of the fleece F is determined by the position of the cut edge of the full wrap, so that the length of the overlapping portion varies, and as a result, the overlapping of the fleece F is caused as described above. Sometimes it cut off at the joint. In this case, too, the operator needs to perform the same operation as at the time of the first spinning of the lap forming machine so that the fleece F is superimposed on the table 11 and conveyed downstream. Such preparatory work requires a lot of time, thus reducing productivity.

[0008] The table 11 used in the lap forming machine is replaced by a single fleece conveyor device as employed in, for example, a sliver wrapping machine, and the fleece is superimposed on the upper surface of the belt. If you, beginning紡時lap-forming machine, or in the polymerization when the cutting fleece to be taken when the fleece is cut, the curl plate P ₁ to P fleece F delivered from each of ₆ tip or fleece conveyor belt on , The front end of each fleece F is automatically conveyed to the downstream side by the traveling of the belt, so that the above-described preparation work that has been manually performed on the table 11 is not required. . However, in the lap forming machine, the fleece F, which has been drafted about 1.5 to 2 times by the sliver wrap machine, is further drafted 5 to 6 times so that the fleece F can be completely gripped by the nipper device of the comber machine. Since it is given, it is not only easy to cut as described above, but also easily affected by airflow. That is, when the whole wrap forming machine table is constituted by one fleece conveyor device, the one-to-one pair of feed rollers is arranged vertically above and below the belt, and a part of this feed roller is provided. In this case, there is no escape for the airflow accompanying the fleece F. As a result, the entrained airflow contained between the lowermost fleece F being polymerized and the belt surface is:
The fleece F collides with a lower roller at a part of the pair of feed rollers, and the fleece F spreads in a lateral direction with respect to the traveling direction, or the part immediately before the pair of feed rollers bends. It may be cut off.

When the fleece F is affected by the accompanying airflow in this manner, the fibers constituting the fleece F move laterally and become wrinkled, or the ears of the fleece F are bent or cut. I do. When such a fleece F is wound as it is, or when the fleece F having a large number of seams is cut and wound around a bobbin of the wrap forming apparatus B,
The thickness of the wound fleece F becomes uneven, and when the fleece is unwound in the next step, not only the outer and inner fibers are licked, but also the irregularity of the combing action occurs, and the inside of the combed fleece is reduced. In some cases, short fibers may remain, resulting in a decrease in the quality of the fleece. Furthermore, if the fleece is cut at the feed roller,
There is a problem that the operator has to perform a preparation work for the superposition, which lowers the production efficiency.

[0010]

SUMMARY OF THE INVENTION The present invention is intended to improve the efficiency of the fleece polymerization by automatically performing preparatory work for polymerization of the fleece at the start of spinning in a lap forming machine or when the fleece is cut. At the same time, an object of the present invention is to prevent the fleece from being disturbed due to the accompanying air flow during the fleece polymerization and to allow a high-quality fleece to be wound.

[0011]

In order to solve this problem, the present invention employs a method in which a plurality of curl plates are arranged above a table along a moving direction of a fleece at predetermined intervals. A plurality of pairs of upper and lower feed rollers are disposed on the upper surface of the table at predetermined intervals along the moving direction of the fleece;
By pulling out the fleece from the same number of supply wraps as the curl plate by the drive rotation of each pair of feed rollers, forming the fleece on the table sequentially while turning over the fleece with the curl plate to form a plurality of layers, In a lap forming machine for rewinding this into a wrap, the feed roller of each pair is
Fleece conveyors are arranged between each
A fleece conveyor is also installed upstream of the flow feed roller.
And set up the table with multiple fleece conveyors.
And the downstream end of the fleece conveyor
Form a predetermined gap between the feed roller and
Between the bottom fleece and the belt surface
The air flow is discharged from the gap.
That is.

[0012]

[Effect of the Invention] At the time of the first spinning, all the fleece conveyors are driven at a low speed, and when the draft device is operated, each fleece pulled out from each supply wrap is moved from the upper end of each curl plate. Sagging,
When the leading end of the fleece reaches the belt surface of the fleece conveyor running at a low speed, the fleece is transported downstream by the low speed running of the fleece conveyor, and another fleece is inverted by a curl plate arranged downstream. The lower part of the fleece is superimposed and overlapped, and the preparation for polymerization is automatically performed. Also, when the fleece is cut during the operation of the lap forming machine, the cut fleece enters under another fleece and is polymerized in exactly the same manner as in the above-mentioned first spinning. Further, at the time of spinning, airflow enters between the fleece of the lowermost layer being polymerized and the belt surface and is entrained, but a predetermined gap is provided between the downstream end of each fleece conveyor and the feed roller. The accompanying airflow is effectively discharged from this gap. Therefore, the disturbance of the fleece due to the accompanying airflow is prevented.

To the upstream side of the fleece conveyor C ₄ is disposed. The heights of the belt surfaces of the fleece conveyors C _{1 to} C ₄ are all the same, and are slightly lower than the positions of the gripping portions of the one-to-one pairs of feed rollers R _{1 to} R ₄ . And both end portions of the fleece conveyor _C 1 -C _3, 1: 1
A predetermined gap is formed between a lower roller (calender roller) among the set of feed rollers R _{1 to} R ₄ , and a downstream end of the fleece conveyor C ₄ and a feed roller predetermined gap is also formed between the lower roller of R _4. Of these gaps, the downstream end of each of the fleece conveyors C _{1 to} C ₄ and one-to-one
The gap 5 formed between the lower roller of the set of feed rollers R _{1 to} R ₄ is formed by the endless belts 6 of the fleece conveyors C _{1 to} C ₄ when the fleece F is superimposed.
It functions as an outlet for the air flow contained and entrained between the lowermost fleece F during the polymerization. As shown in FIG. 3, each of the fleece conveyors C _{1 to} C ₄ has a configuration in which an endless belt 6 is mounted between a driving roller 7 a and a driven roller 7 b supported by a pair of conveyor frames 1 and 1. a is, the driving roller 7a which is disposed on the downstream side along the moving direction Q of the fleece F is, has a configuration in which each is rotated by a separate drive motor M ₁ ~M _4. In this embodiment, four independent fleece conveyors C
₁ -C ₄ are each a structure in which separate drive motor _M 1 ~M ₄ is driven, the fleece conveyer _C 1 -C ₄
Can be individually controlled, but the power of one drive motor is transmitted via the transmission device to each of the fleece conveyors C ₁ to C _1.

When the full wrap is placed on each set of lap rollers 2 for one-on-one for the first spinning, a signal is issued from a machine operation control device (not shown), each drive motor _M 1 ~M ₄ is activated. As a result, each of the fleece conveyors C _{1 to} C ₄ is driven, and the upper half of each endless belt 6 runs at a low speed along the moving direction Q of the fleece F. Then, by driving each draft device D,
Fleece F drawn from the supply lap L is reached the curl plate P ₁ to P ₆ after being drafted, as shown in Figure 4 by a two-dot chain line in a state of hanging from the upper end. When the fleece F is further drawn out from the supply lap L, the distal end portion Fa of the fleece F is placed to reach the upper surface of the endless belt 6 of the fleece conveyor C ₁ -C ₄ which are low speed, then The fleece F is transported downstream by the endless belt 6 traveling. Each fleece F drawn from each supply wrap L
Since all of them are conveyed to the downstream side as described above, the front end portion Fa of the upstream fleece F enters under the downstream fleece F and is sequentially superimposed, so that each time the paper passes through one curl plate. the number of layers of fleece F is increased by one, the fleece F that has passed through the curl plate P ₆ of the most upstream
But becomes six layers passes through the curling plate P ₁ downstream of, entering the lap forming device B through a portion of the centering plate 4. As described above, the fleece F is the draft device D, the curl plate _P 1 to P ₆ and fleece conveyor C
Via ₁ -C _4, until they rewound on a bobbin of the lap forming device B, the lap forming machines are approximately normal during operation 1 /
Operated at 3-1 / 2 rate, the endless belt 6 fleece conveyor _C 1 -C ₄ circulates traveling at this same speed.

As described above, when the fleece F, which has been polymerized into a plurality of layers (six layers in this embodiment) at the time of the first spinning, is wound around the bobbin of the wrap forming apparatus B, the lap forming machine is lapsed after a certain period of time. Starts high-speed operation. The spinning speed during high-speed operation is 100 to 120 m / min. During the high-speed operation of the lap forming machine, each fleece conveyor C _1-
C ₄ may be directly allowed to continue operation, it may be stopped. In the former case, each fleece conveyor C _1-
There are advantages help travel fleece F by the traveling of the C _4, the upper surface of the endless belt 6 running the fleece F
Polymerized surface. In the latter case, the fleece conveyer C ₁ -C ₄ can play the same function as the table of the conventional apparatus, the polymerization surface, the upper surface of stationary each endless belt 6.

The case of operating the respective fleece conveyor C ₁ -C _4, or in any case to stop also, the lowermost fleece F which is being polymerized, between the belt surface of each fleece conveyor C ₁ -C ₄ to but airflow is entered in associated, predetermined gap 5 between the rollers of the lower constituting the downstream end of the fleece conveyor C ₁ -C _4, a pair of feed rollers R ₁ to R ₄ Due to the formation, the associated airflow is effectively discharged through this gap 5. For this reason, the disturbance of the fleece F due to the accompanying airflow does not occur.

During the spinning, when the supply wrap L becomes small, the lap forming machine is stopped, the supply wrap L is replaced, and the rear end of the fleece F preceding by the automatic lap splicer (not shown); splicing by overlapping the tip portion of the succeeding full supply wrap L, but in this case, the operation of the fleece conveyor C ₁ -C ₄ stops. Then, when the splicing work of the fleece F by the automatic lap splicing device is completed,

Are inserted under the fleece F on the downstream side and are sequentially superimposed to prepare for the polymerization of the fleece F. In both the case of the above-mentioned first spinning and the case of joining the fleece F, the spinning speed of the machine is 100 m / mi.
In the case of n, the tip of fleece F or fleece F
Is transferred by a fleece conveyor,
The time required to be gripped by the downstream feed roller or to reach the lower portion of the downstream curl plate was about 3 seconds.

Further, the plurality of fleece conveyors C _{1 to} C ₄ , each having an upper surface serving as a superposed surface and functioning as a table for superposing the fleece, can be operated intermittently. Fly and dust may fall and accumulate on both ends of the belt surface of the fleece conveyors C _{1 to} C ₄ in the width direction and where the fleece F is not placed in a normal state. , This fleece conveyor C
When the ₁ -C ₄ is intermittently operated, fiber dust is deposited on the upper surface, the dust or the like is carried to the downstream side, and is discharged from the gap 5 between the downstream end and the feed roller fleece conveyor. For this reason, it is possible to prevent foreign matter, such as fly waste and dust, from entering the fleece being spun, thereby reducing the quality thereof.

Are formed, the following effects can be obtained.
(1) In the case of starting spinning, when the fleece is cut, the cut fleece is polymerized, or when the supply flap is reduced, and the fleece is joined, the leading end of the fleece on the running fleece conveyor is used. Alternatively, the seam portion is automatically conveyed to the downstream side, and each fleece is sequentially superimposed, so that preparation work for fleece polymerization, which has conventionally depended on manual labor, is automated, and the preparation time is reduced. The efficiency is greatly shortened, and the safety is improved because the worker is not accidentally pinched his own hand between the feed rollers. (2) Since a predetermined gap is formed between the downstream end of each fleece conveyor and the feed roller, the air flow contained and entrained between the lowermost fleece and the belt surface is:
Since all of the air is discharged from the gap, the turbulence of the fleece due to the accompanying airflow is prevented, and a high-quality fleece can be spun. (3) When the fleece conveyor is operated intermittently during spinning of the fleece, the fly waste, dust, etc., which are accumulated on the fleece-side end portions of the fleece conveyor where no fleece is placed, are conveyed to the downstream side. Thus, the paper can be discharged from the gap between the downstream end of the fleece conveyor and the feed roller. For this reason, it is possible to prevent fly waste and the like from entering the fleece being spun.
