[Industrial applications]

 In the lap forming machine equipped with the ribbon wrap machine, the present invention forcibly feeds the cut lap fleece to the downstream side without manual work when the uppermost lap fleece is cut at seams or the like. It relates to a lap fleece feeding device.

[0002]

[Prior art]

A conventional wrap forming machine mounted on a ribbon wrap machine will be described with reference to FIGS. 7 and 8. This lap forming machine superimposes a plurality of draft devices D for drafting a plurality of lap fleeces F (hereinafter simply referred to as “fleece”) and a plurality of fleeces F drafted by each draft device D. A lapping fleece superposing device A'for layering together and a lapping forming device B for winding up the layered fleece F by the superposing device A'to a bobbin into a lap. It is composed of. The lap fleece polymerization apparatus A 'is curled plate P ₁ to P ₆ of a plurality above the table 1 (six in the illustrated example), at a predetermined interval along the moving direction Q of the fleece F It is arranged. On the upstream side of the lap fleece superposing apparatus A'with reference to the flowing direction of the free- sleeves F, a plurality of sets of wrap rollers 2 for supporting the supply wrap L are provided. The fleece F drawn from the supply lap L is provided between the curl plates P _{1 to} P ₆ and the curl plates P _{1 to} P ₆ provided in parallel with the curl plates P _{1 to} P ₆ , respectively. Drafting devices D for drafting are respectively provided.

On the table 1 which constitutes the lap fleece stacking apparatus A ′, several pairs of feed rollers R 1 which are one-to-one for sandwiching the fleece F from the upper and lower sides and feeding it to the downstream side are provided. It is provided at a predetermined interval along the moving direction Q. The feed roller R is composed of a press roller arranged above and a calendar roller arranged below. Further, the table 1 is provided with a fleece guide 3 for preventing the fleece F from moving laterally when the fleece F moves. The fleece guides 3 are provided so as to face each other at a predetermined interval (corresponding to the maximum width of the fleece F) along the direction orthogonal to the moving direction Q of the fleece F. A large number of sets of fleece guides 3 which are one set are provided at predetermined intervals along the moving direction Q of the fleece F.

Each of the frets F drawn from each of the supply wraps L supported by the pair of wrap rollers 2 is drafted by a predetermined amount by the drafting device D, and then each of the fleeces F is attached to each of the curl plates P. _{While the} direction of movement is changed by 90 ° by _{1 to} P _6, they are inverted, and the fleece F on the upstream side is piled up one after another so as to move on the table 1. In this way, the fleece F laminated in a plurality of layers on the table 1 enters the lap forming device B through the width-shifting plate 4 and is rewound on the bobbin to be a lap.

If any of the supply laps L runs out while the fleece F is being wound by the lap forming machine, the operator stops the machine base, puts a full lap on the pair of lap rollers 2, and The full-lap fleece F is used as the succeeding fleece F, and the trailing end of the preceding fleece F is overlapped and continued. In this case, if the overlapping portions of the fleeces F that are adjacent to each other are short, the seams of the fleeces F will be cut in the draft device D or the portions of the curl plates 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 gripped between the top roller and the bottom roller (neither of which is shown) of the draft device D. The fleece F is cut off at the overlapping portion.

The above-mentioned lap splicing is performed manually, but there is a device for automatically performing this lap splicing. This automatic lap splicing device has a cut end of a full lap supported by a pair of lap rollers 2. A suction tube is applied to the, the cut end is peeled off, and it is superposed on the rear end of the preceding fleece F. In the case of this device, the length of the overlapped portion of the fleece F is determined by the position of the cut portion of the full wrap, so that the length of this overlapped portion occurs, which causes the overlap of the fleece F as described above. It may be cut at the mating part.

The draft device D is provided in a plurality of rows (six rows in the illustrated example), and even if the fleece F is cut off, the fleece on the table 1 upstream of the cut portion is the cut fleece. Since it passes below F, it is guided by the fleece F on the upstream side, conveyed to the downstream side, and superposed. However, when the fleece F of most upstream will be off, since the fleece is not to induce fleece F in which the cut, as shown in FIGS. 7 and 8, it is the most upstream of the curl plate P ₆ below Is piled up and clogged at the portion of the wrap forming machine, and one piece of the fleece F is deficient and is wound up on the bobbin of the lap forming device B. Such a wrap cannot be used in the subsequent process due to lack of gelling.

Therefore, in the present application, as Japanese Patent Application No. 2-24784, an air nozzle is attached to the upstream side portion of the curl plate arranged on the most upstream side of the table, and the air nozzle is connected to the downstream side. By fusing an air flow toward, the fleece that was cut at the seams, etc., was forced to be sent to the downstream side, and an application was filed to prevent the above problems. This fleece feeding device is a great technological advancement based on the fact that when the fleece breaks, the machine base is stopped and the fleece is manually guided to the downstream side and overlapped with other fleeces. However, since the fleece joint part is heavier than other parts, unless the amount of airflow is increased, the broken fleece can be effectively sent to the downstream side. I can't.

[0009]

[Problems to be solved by the device]

 The present invention has an object to reliably feed the fleece to the downstream side without stopping the machine base so that the fleece is superposed with other fleeces when the uppermost fleece is broken in the lap forming machine. It was made as.

[0010]

[Means for Solving the Problems]

 To solve this problem, the means adopted by the present invention is that a plurality of curl plates are arranged above the table along the moving direction of the fleece at predetermined intervals, and the upper surface of the table is A plurality of pairs of upper and lower feed rollers are arranged at a predetermined interval along the moving direction of the fleece, and the same number of supply wraps as that of the curl plate are provided by the drive rotation of each pair of feed rollers. In the lap forming machine for pulling out each fleece, successively laying it up on the table while forming the plural layers while reversing the fleece by the curl plate, and re-winding it into a lap, The uppermost part of the table on the upstream side of the feed roller is composed of a fleece conveyor.

[0011]

[Function of the device]

 The upstream side of the uppermost feed roller in the table is composed of a fleece conveyor, and this fleece conveyor is always operated. If the fleece breaks at seams or the like during operation of the machine stand, the fleece hangs down from the curl plate, and when the tip reaches the fleece conveyor, the fleece is moved by the running of the fleece conveyor. It is forcibly sent to the downstream side. In this way, when the tip of the cut fleece reaches the part of the feed roller, the cut fleece is reliably pulled out by the feed roller and enters below another fleece to be polymerized.

【Example】

Hereinafter, the present invention will be described in more detail with reference to examples. The same parts as those described in the above-mentioned "Prior Art" are designated by the same reference numerals, and only the characteristic parts of the present invention will be described without duplicating description. In FIGS. 1 to 4, a pair of conveyor frames 5 and 5 is arranged in a portion perpendicular to the moving direction Q of the fleece F at a portion immediately below the curl plates P _{1 to} P ₆ which constitute the lap fleece superposition apparatus A. Are arranged at a fixed interval. Between the conveyor frames 5 and 5, four pairs of feed rollers R _{1 to} R _{4, which} are _one to one, are provided at predetermined intervals along the moving direction Q of the fleece F. . That is, the feed roller R ₁ is arranged on the downstream side of the lower end of the curl plate P ₁ with a predetermined gap from the lower end, and the feed rollers R _{2 to} R ₄ are respectively curled. The plates P ₂ , P ₄ , and P ₆ are arranged on the slightly downstream side of the lower ends and close to the lower ends.

There is a one-to-one set, and between each set of four sets of feed rollers R _{1 to} R ₄ arranged between a pair of conveyor frames 5 and 5, from the downstream side to the upstream side. The fleece conveyors C _1, C _{2 and} C ₃ are arranged respectively toward each other. Further, a fleece conveyor C ₄ is arranged according to the present invention on the upstream side of the feed roller R ₄ arranged in the uppermost stream. The heights of the belt surfaces of the respective fleece conveyors C _{1 to} C ₄ are all the same, and are slightly lower than the positions of the gripping portions of the feed rollers R _{1 to} R ₄ of one to one set. As shown in FIG. 3, each of the fleece conveyors C _{1 to} C ₄ has an endless belt 7 mounted between a driving roller 6 a and a driven roller 6 b supported by a pair of conveyor frames 5, 5. a configuration, the drive rollers 6a 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.

When the supply wrap L becomes low during spinning, the wrap forming machine is stopped and the supply wrap is replaced, and the preceding fleece F is manually or by an automatic lap joining device (not shown). The rear end portion of the rear end portion and the front end portion of the succeeding full supply lap L are overlapped and spliced together. In this way, when the splicing work of the fleece F by the human or the automatic lap splicing device is completed, the lap forming machine is automatically started, and the fleece conveyor C arranged below the uppermost curl plate P _{6 4} including fleece conveyor C ₁ -C ₄ total hand starts traveling.

As described above, the portion (joint) where the fleece F is overlapped is easier to cut than the other portions, and when the uppermost fleece F is cut, it is guided to the downstream side. Since there is no such fleece, the fleece F is deposited on the lower portion of the curl plate P ₆ , and the fleece F is wound up on the bobbin of the lap forming apparatus B while one piece of the fleece F is insufficient. However, in the present invention, since the fleece conveyor C ₄ is arranged in the lower part of the uppermost curl plate P ₆ , the fleece conveyor C ₄ is cut as shown in FIGS. 3 and 4. fleece F is hanging from the upper end of the curl plate P _6, when the leading end portion Fa is in contact reaches the fleece conveyor C _4, the fleece F is Ru is conveyed to the downstream side by the traveling of the fleece conveyor C _4. When the front end Fa of the cut fleece F is sandwiched by the pair of upper and lower feed rollers R ₄ , the cut fleece F is forced to the side of the fleece conveyor C ₃ by the pulling action of the feed roller R _4. Be drawn in. The cut fleece F is drawn into the side of the fleece conveyor C ₃ for a predetermined length, and the tip end Fa thereof reaches below another curl plate P ₅ adjacent to the curl plate P ₆ , and this curl plate P ₅ When entering the lower part of the fleece F that has passed through, both fleeces F are overlapped and in this state they are transported to the downstream side. In this way, even when the preparatory work for the polymerization of the fleece F is performed and the uppermost stream of the fleece F is cut during this, the cut fleece F is sent to the downstream side without any trouble and Until the fleece F passes through the draft device D, the curl plates P _{1 to} P ₆ and the fleece conveyors C _{1 to} C ₄ and is rewound on the bobbin of the lap forming device B, the lap forming machine operates normally. Operating at a speed of about 1/3 to 1/2 of the speed, each of the fleece conveyors C _{1 to} C ₄ travels at the same speed.

As described above, when the fleece F polymerized into a plurality of layers (six layers in this embodiment) at the time of splicing the fleece F is wound around the bobbin of the lap forming apparatus B, lap formation is performed after a certain time has elapsed. The machine starts high speed operation. Oite during high-speed operation of the lap forming machines, fleece conveyer C ₁ -C ₃ may be allowed to continue operating as it speeds, but may be stopped, fleece conveyor disposed at the most upstream At C ₄ , the operation is continued as it is. As a result, during the polymerization of the fleece F, even if the upstreammost fleece F is broken for some reason, the broken fleece F is automatically fed to the downstream side by the same action as described above. Therefore, it is possible to prevent the fleece F from being wound up on the bobbin of the lap forming apparatus B in a defective state in which one layer of the fleece F is missing by being polymerized with another fleece F.

In the above embodiment, the most upstream feed roller R on the table of the lap forming machine is used. _Four On the upstream side of the fleece conveyor C_FourNot only the four feed rollers R₁~ R_FourFleece conveyor C between₁~ C₃By arranging, the entire table of the lap forming machine is configured with a fleece conveyor. With this configuration, the leading end of each fleece can be automatically conveyed to the downstream side during the initial spinning of the lap forming machine. The present invention is not limited to the above-described embodiment, though it has the advantage of being able to be performed in time. For example, as shown in FIG. 5, the feed roller R in the table is₁Same as R_FourIn between, the whole fleece conveyor C₀In the same manner as in the above embodiment, the fleece polymerization preparatory work during the initial spinning may be automatically performed. In addition, in FIG.₀Is a fleece conveyor C ₀ The drive motor of is shown. Further, as shown in FIG. 6, the feed roller R₁~ R _Four It is also possible to use the same table 1 as in the related art during the period.
