BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for stacking and transporting fleeces fed from a plurality of draft sections of a ribbon wrap machine.

[0002]

2. Description of the Related Art In a conventional ribbon wrap machine, for example, 6
A guide table is arranged along the front side of the lap supply section of the head. In this ribbon wrap machine, when the number of supply wraps in the wrap supply section becomes low, a new full wrap is exchanged for lap joining. The continued lap is supplied to the draft section as it is, and the draft that has become a fleece is changed to a right angle by the curl plate and sent out onto the guide table. In the fleece, the fleece sent from the draft section located downstream is sequentially stacked on top, and the fleece in the uppermost draft section is the lowest layer.

[0003]

[Problems to be Solved by the Invention] If the lap spliced in the lap supply section has a splicing failure or if there is a draft failure in the draft section, the supplied fleece is cut between the curl plate and the guide plate and hangs down. . Even if the fleece of the downstream draft part excluding the most upstream draft part farthest from the lap winding part cuts and hangs as described above, if the fleece upstream of it flows on the guide table, it will ride on the fleece. It will be transported without any trouble. However, when the fleece in the most upstream draft cuts and hangs down, there is no flow of other fleece on the guide table, so the hung down fleece collects on the guide table and is not transported. There was a problem of making. It is also conceivable to carry all the fleece by placing it on a belt conveyor instead of a fixed guide table that receives the fleece, but with this method, the belt conveyor becomes long, and as a result, the belt meanders and fleece from 6 heads is placed on the belt. It was difficult to place them in line with each other, and there was a drawback that the overlapping of both ends of the fleece was significantly different.

[0004]

In order to solve the above-mentioned problems, the present invention relates to a ribbon wrap machine for stacking a plurality of fleeces sent from a plurality of draft parts and transporting them to a wrap winding part. It is divided into a first draft part group arranged on the upstream side in the transport direction and a second draft part group arranged on the downstream side, and a position facing the first draft part group in front of the first draft part group. And a belt conveyor for fleece conveyance, which circulates in the direction of the lap winding section, is disposed in front of the second draft section group, and a second draft group is provided between the downstream end of the belt conveyor and the wrap winding section. A fixed guide table that guides the fleece sent from the draft part of the belt conveyor is arranged, and the fleece sent by the belt conveyor is pressed to the vicinity of the downstream end of the belt conveyor. Characterized by being arranged roller for.

[0005]

[Operation] When fleeces sent from a plurality of draft parts are overlapped and conveyed downstream, when the fleece sent from the furthest upstream draft part farthest from the wrap winding part is cut off, the fleece hangs down on the belt conveyor. And is conveyed downstream by the circulation thereof in the direction of the wrap winding section. This fleece is fed to the guide table further downstream by pressure contact rotation of the fleece fed from the draft section immediately downstream and the roller near the downstream end of the stack belt conveyor on the belt conveyor. On the guide table, the fed fleece from the upstream is superposed on the fed fleece from the upstream, and the fleece is further superposed from above to form a wrap, which is then conveyed to the lap winding section.

The lap winding unit 29 is a lap winding device 58 that winds a calender device 55 that press-contacts the overlapped fleeces 9 to 14 conveyed from the fleece transfer device 1 and a lap sheet 56 that has been press-contact polymerized onto a bobbin 57.
It has.

Next, the operation of the above configuration will be described. The wraps 3a to 8a of the wrap supply units 3 to 8 are draft units 15 to
It is drafted at 20 and sent out to the upper surface of the curl plates 21 to 26 as fleece 9 to 14 and the curl plate 21.
At ~ 26, the traveling direction is turned to the right at a right angle and is sent to the fleece transfer device 1 below. The fleeces 9 and 10 sent out from the draft section 15 farthest from the lap winding section 29 and the draft section 16 immediately downstream of the lap take-up section 29 are piled on the fleece 9 on the lower belt conveyor 30, and the fleece 10 is circulated by the belt 37. Be transported to. The fleeces 9 and 10 are pressure-contact polymerized by the belt 37 and the top roller 41, and are sent out onto the guide table 28 on the downstream side. The superposed fleeces 9 and 10 are superposed with the fleeces 11 to 14 on the guide tables 28a and 28b at positions corresponding to the fleeces 11 to 14 from the draft parts 17 to 20. Fleeces 9 to 14 are guide tables 28a, 28b, 28.
bot rollers 35a, 35b, 35c and top rollers 41a, 41 between the c and the tip of the guide table 28c.
They are pressure contact polymerized with b and 41c and are conveyed to the lap winding section 29. The fleeces 9 to 14 are sent to the lap winding section 29 and pressure-contact polymerized in the calender section 55 to become the fleece 56, which is wound on the lap bobbin by the lap winding device 58.

Now, in the most upstream draft section 15,
Consider a case where the fleece 9 is cut due to a defect such as a lap joint. When the fleece 9 is cut, the cut end hangs down on the belt conveyor 30, is placed on the conveyor belt 37, is conveyed to the downstream, is pressure-contact polymerized with the fleece 10 immediately downstream by the top roller 41, and is sent further downstream.
Therefore, even if the fleece 9 is cut off at the most upstream draft portion 15, the fleece does not accumulate as in the conventional case. Further, since the belt conveyor 30 has a very short length corresponding to the two draft portions 15 and 16, the belt 37 does not meander and the fleece ears overlap well.

The present invention is not limited to the above-described embodiment. For example, as shown in FIG. 4, the conveyor belt 37 of the fleece conveyor belt conveyor 30 is a conveyor belt 37A which is extended in the downstream direction to form a conveyor belt 37A. Drive roller 3 for driving the conveyor belt, which is made to come close to the top roller 41a and the bottom roller 35a for fleece pressure
5A is provided. Then, the upstream side fleece and the downstream side fleece sent by the transport belt 37A may be brought into pressure contact with each other by the top roller 41a for fleece pressure contact.

[0014]

As described above, in the present invention, the plurality of draft parts are divided into the first draft part group arranged on the upstream side in the fleece transport direction and the second draft part group arranged on the downstream side, A belt conveyor for transporting a fleece that circulates in the wrap winding direction is arranged in front of the first draft portion group, and a fixed guide that guides the fleece fed from the second draft portion group in front of the second draft portion group. A table is arranged, and a roller for pressing the fleece sent by the belt conveyor is arranged in the vicinity of the downstream end of the belt conveyor, so even if the fleece sent from the most upstream draft section hangs down, It rides on the belt conveyor and overlaps with the fleece of the downstream draft section, and is pressed by the rollers to be integrated and sent out to the guide table following the lap winding section for smooth conveyance. Kill. Therefore, even if the fleece that comes out of the farthest draft part is cut, the fleece is not accumulated on the table, and it is possible to prevent a bad lap from being formed in the lap winding part. Also, the total length of the belt conveyor is
Since the length is shorter than that of all the draft parts facing the front surface, there is an advantage that the degree of meandering of the belt conveyor can be reduced and the difference in the overlap between the ends of the fleece can be reduced.
