Abstract

PROBLEM TO BE SOLVED: To heighten an operation efficiency of yarn-repairing operation, or the like, carried out between a sizing vessel and a drier, and to evade the danger caused by a drying cylinder. SOLUTION: This warp-sizing machine 1 has an assistant drying cylinder having a diameter smaller than the drying cylinder and installed in the upper part of a sizing vessel 20 and in the position lower than the drying cylinder present at the most upstream side in the traveling direction of a warp yarn sheet 30 of a drier 10. The length of an interval at which the warp yarn sheet 30 becomes free can be shortened because the warp yarn sheet 30 is introduced from the sizing vessel 20 through the assistant drying cylinder to the drier 10, and even if the yarn with a hard twist, or the like, is used, the yarn hardly causes rolling in the width direction of the warp yarn sheet 30. Further, the drier 10 can be installed in a position in which the danger is hardly provided to a person under operation, and a sufficient space for the operation can be secured.

[0002]

2. Description of the Related Art Conventionally, a warp sizing machine in which a drying device is provided at a position higher than a sizing tank is disclosed in Utility Model Registration No. 2586117.
Issue.

[0003]

In the above prior art, a space is required between the glue tank and the drying device to provide a work space for an operator to work for repairing the yarn near the warp sheet. . However, due to the long interval, the length of the section where the warp sheet becomes free during this time, in particular, from the end point of contact of the warp sheet at the roller on the downstreammost side of the warp sheet in the glue tank, the drying cylinder on the most upstream side of the warp sheet , The distance to the warp sheet contact start point becomes longer. Therefore, for example, in the case of a highly twisted yarn, a hard yarn, a yarn that is easily twisted by the influence of heat or water, the yarn rolls in the width direction of the warp sheet while the warp sheet is running, and the yarn adjacent to the warp sheet is May be intertwined.

[0004] In order to solve the above problems, it is necessary to shorten the section length in which the warp sheet becomes free.
Simply lowering the dryer position to reduce the section length reduces the work space. The above is the same when lowering the position of a part of the drying device, particularly only the drying cylinder on the most upstream side in the warp sheet traveling direction (FIGS. 3 and 4). Such a reduction in the working space entails danger in the work due to the proximity of the high-temperature drying cylinder, and also reduces the work efficiency.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has improved the efficiency of thread repair work and the like performed between a gluing tank and a drying device, and has avoided the danger of a drying cylinder. The purpose is to do.

[0006]

The warp sizing machine according to the present invention is arranged so that the drying cylinder is located above the sizing tank and lower than the drying cylinder on the most upstream side in the warp sheet traveling direction of the drying device. An auxiliary drying cylinder having a smaller diameter is provided, and the warp sheet is guided from the sizing tank to the drying device via the auxiliary drying cylinder.

According to the structure of the present invention, an auxiliary drying cylinder having a smaller diameter than the drying cylinder is provided at a position lower than the drying cylinder at the most upstream side in the warp sheet traveling direction of the drying device and above the gluing tank. ing. For this reason, the section length in which the warp sheet becomes free can be shortened, and for example, even if the yarn has a strong twist, it is difficult for the yarn to roll in the width direction of the warp sheet.

Further, since the diameter of the auxiliary drying cylinder is smaller than the diameter of the drying cylinder on the most upstream side in the warp sheet traveling direction, even if the contact start point of the warp sheet is lowered, the auxiliary drying cylinder is reduced by the small diameter around the auxiliary drying cylinder. Can secure a large amount of space, and reduce obstacles such as a yarn repairing operation performed between the gluing tank and the drying device. Further, the drying device can be provided at a position where there is no danger during the operation, and a sufficient space for the operation can be secured. For this reason, the danger of approaching a high-temperature drying cylinder can be avoided, and the working efficiency can be improved.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings.

In FIG. 1, a warp sizing machine 1 includes a warping beam (not shown) and a sizing tank 20, a drying apparatus 10 provided at a position higher than the sizing tank 20, and a drying apparatus 10 above the sizing tank 20. Among them, the position is lower than the drying cylinder 11a on the most upstream side in the warp sheet traveling direction,
It comprises an auxiliary drying cylinder 12 provided between the gluing tank 20 and the drying cylinder 11a, and a pre-beam (not shown).

The warp sheet 30 unwound from the warping beam is glued in a gluing tank 20 and is pulled out substantially vertically from between a pair of squeeze rollers 21 and 22, which are rollers at the most downstream side of the warp sheet in the gluing tank 20. Then, it is guided to the drying cylinder 11a via the auxiliary drying cylinder 12 located above the gluing tank 20. That is, it enters the drying device 10. After the drying is completed, the warp sheet 30 is wound around the pre-beam.

The drying device 10 includes a plurality of drying cylinders 11.
However, at least the lowermost end of the drying cylinder 11a, which is located on the most upstream side in the traveling direction of the warp sheet 30 in the drying cylinder 11, is provided at a position higher than the lowermost end of the auxiliary drying cylinder 12.

The diameter of the auxiliary drying cylinder 12 is smaller than that of the drying cylinder 11a. The temperature of the auxiliary drying cylinder 12 can be set separately from that of the drying cylinder 11, and an appropriate temperature can be set according to the yarn type.
Among them, it is preferable to set the temperature to be higher than that of the drying cylinders 11a and 11 from the viewpoint of preventing the adhesion of the scale to the surface of the auxiliary drying cylinder 12 and compensating for the lack of heat capacity. For the same reason, it is preferable that the surface of the auxiliary drying cylinder 12 be made of a material such as Teflon (registered trademark) coating or the like, which is not easily adhered to the paste.

In the work space 40, the glue tank 2
The thread repair operation of the warp sheet 30 or the replacement operation of the warp sheet 30 between the zero and the auxiliary drying cylinder 12, the cleaning of the gluing tank 20, and the cleaning of the glue residue attached to the roller provided in the gluing tank 20 are performed. .

The auxiliary drying cylinder 1 has a sufficient working space 40 for performing the above operations.
The diameter of 2 needs to be reduced. The diameter of the auxiliary drying cylinder 12 is preferably not more than 2/3 of the diameter of the drying cylinder 11a, more preferably not more than half.

By providing the auxiliary drying cylinder 12 as described above, the warp sheet 30 in the gluing tank 20 is provided.
Squeeze roller 2 which is the most downstream roller in the traveling direction
The distance 50 from the contact end point A of the warp sheet 30 of Nos. 1 and 22 to the contact start point B of the warp sheet 30 in the auxiliary drying cylinder 12 is the contact end of the warp sheet 30 at the squeeze rollers 21 and 22 shown in FIG. Warp sheet 30 from point A to drying cylinder 11a
Can be shortened as compared with the distance 50a to the contact start point B.

The auxiliary drying cylinder 12 may perform a negative rotation or a more positive rotation depending on the warp sheet 30. The driving source during the positive rotation may be provided separately or may be connected to the driving source of the drying cylinder 11.

[0018]

As described above, according to the present invention, the length of the section where the warp sheet becomes free, that is, from the contact end point of the warp sheet in the roller on the most downstream side in the warp sheet traveling direction in the gluing tank, It is possible to further reduce the distance to the contact start point of the warp sheet in the drying cylinder on the most upstream side in the warp sheet traveling direction, and it is possible to prevent, for example, the rolling of strongly twisted yarn.

Further, since the diameter of the auxiliary drying cylinder is smaller than the diameter of the drying cylinder, the space is widened, so that it is possible to secure a sufficient working space for performing a yarn repairing operation of the warp sheet. In addition, it is possible to avoid the danger that the high-temperature drying cylinder approaches the operator, thereby improving the working efficiency.
