Description

The present invention relates to a warp gluing device for a weaving preparation machine.

Patent Document 1 discloses a warp gluing machine. The warp gluing machine guides a large number of sheet-like wefts, that is, warp sheets, to a glue tank, squeezes the glue with a squeeze roller, and then divides the glued warp sheets into two warp sheets. It is dried in a separate drying cylinder.

However, since the warps are connected by fuzz after gluing, the warp sheet is not sufficiently separated into two warp sheets immediately after drawing. Further, since the degree of connection between the warp yarns varies depending on the state of the glue, the separation position of the warp sheet changes. Furthermore, if the warp yarns are strongly connected, the separation is delayed, drying proceeds in the connected state, and the dried warp sheet is separated, so the warp sheet is irregularly separated and the length Many irregular fluff occurs.

Also, the gluing technique of Patent Document 2 is to guide a warp sheet to a paste tank, glue the warp sheet with a squeeze roller, and then squeeze the warp sheet with a comb provided above the gluing device. This makes it easier to separate the warp sheets than the technique of Patent Document 1. However, on the other hand, since the number of pins constituting the comb is less than the number of warp yarns, the warp yarns that were not separated by the pins are separated above the separated ones, and as a result, fluffs with irregular lengths are generated. To do.
Japanese Utility Model Laid-Open No. 5-56888 JP-A-3-227449

The object of the present invention is to eliminate the variation in the length of the fluff and to improve the weaving property of the warp by dividing the length of the fluff when dividing the warp sheet from the gluing device to the upper drying device into two warp sheets. That is.

Based on the above problems, the present invention comprises a gluing device for gluing the warp sheet and a cylinder drying device located above the gluing device, and the warp sheet after gluing by the gluing device is divided into two parts. In a warp gluing machine that guides each warp sheet to the two drying cylinders of the cylinder drying device, a plurality of warp sheets are formed in the inner region of the warp sheet formed between the two warp sheets connected to the two drying cylinders from the gluing device. The rods are provided corresponding to the respective warp sheets, and the plurality of rods are rotationally driven at a peripheral speed slower than the traveling speed of the warp sheets, and are in contact with only the corresponding warp sheets. The two systems of cylinder drying devices are located above the gluing device, and the most upstream drying cylinders of each system are separated from each other in the direction intersecting the warp sheets (surfaces including the sheets).

The positional relationship between the outer diameters D1 and D2 of the plurality of rods and the inter-axis distance L of each rod in the direction intersecting the running direction of the warp sheet is set in a range represented by the expression L ≦ (Dl + D2) / 2. (Claim 2).

The plurality of rods are rotationally driven in directions opposite to each other, and are rotated in the same direction as the traveling direction of the corresponding warp sheet on the surface in contact with the warp sheet. Further, the plurality of rods are rotationally driven in directions opposite to each other, and are rotated in a direction opposite to the traveling direction of the corresponding warp sheet on the surface in contact with the warp sheet. Further, the plurality of rods are rotationally driven in directions opposite to each other, and are provided so that the rotation direction in the same direction or the opposite direction to the traveling direction of the corresponding warp sheet can be selectively set on the surface in contact with the warp sheet. ).

Furthermore, the present invention comprises a gluing device for gluing a warp sheet and two systems of cylinder drying devices located above the gluing device. The warp sheet after gluing by the gluing device is divided into two and each warp divided In the warp gluing machine that guides the sheet to the cylinder drying device, a plurality of rods are provided in the inner region of the warp sheet formed between the two warp sheets connected from the gluing device to the two drying cylinders of each cylinder drying device. Provided corresponding to the warp sheet, a plurality of rods are rotationally driven at a peripheral speed slower than the traveling speed of the warp sheet, and are in contact with only the corresponding warp sheet. In the outer region, rods are provided corresponding to the respective warp sheets, and each rod is rotationally driven at a peripheral speed slower than the traveling speed of the warp sheets. , It is in contact with the corresponding warp sheet (claim 6).

According to claim 1, in the warp gluing machine, a plurality of rods correspond to each warp sheet in the inner region of the warp sheet formed between the two warp sheets connected from the gluing device to the drying cylinder of each cylinder drying device. The plurality of rods are rotationally driven at a peripheral speed slower than the traveling speed of the warp sheet and are in contact with only the corresponding warp sheet. That is, since a plurality of rods are provided in the inner region of the warp sheet so as to contact only the corresponding warp sheet, the warp sheet can be separated at a fixed position closer to the gluing device, and the length of the fluff can be reduced. The fluff generated when the rod contacts with the warp sheet can be laid down, that is, the fluff can be laid down, and glue or fluff adheres to the rod by a warp sheet different from the corresponding warp sheet, and further corresponds Adhering to the warp sheet is avoided. Furthermore, since the rod is driven to rotate, the fluff or glue of the rod due to contact with the corresponding warp sheet rotates with the rod and contacts the warp sheet, and adheres to the warp sheet before it collects in the rod and becomes a large lump. Large warp glue and fluff adhere to the warp sheet, so that when the warp yarns are separated, the warp yarns can be prevented from being damaged, and the warp yarns are not separated, so-called double yarns, It is possible to avoid the formation of three yarns, and it is possible to suppress the occurrence of defective opening in the loom. Further, since the peripheral speed of the rod is slower than the traveling speed of the warp sheet, it is possible to suppress the fluff and glue adhering to the rod from being scattered by the rotation.

According to claim 2, since the positional relationship between the outer diameters D1 and D2 of the plurality of rods and the inter-axis distance L of the rods is set to be expressed by the formula L ≦ (Dl + D2) / 2, the plurality of rods Can be disposed near the gluing device in weak contact with only the corresponding warp sheets, and can be fluffed without rubbing the warp sheets strongly, whereby the lengths of the fluffs are made uniform.

According to claim 3, the plurality of rods are driven to rotate in opposite directions and are rotated in the same direction as the traveling direction of the corresponding warp sheet on the surface in contact with the warp sheet. Since the rod rotates and contacts the warp sheet from the upstream side in the traveling direction, it adheres to the warp sheet, so that no glue or fluff accumulates on the rod.

According to the fourth aspect, the plurality of rods are driven to rotate in directions opposite to each other and rotated in the direction opposite to the traveling direction of the corresponding warp sheet on the surface in contact with the warp sheet. The relative speed of the yarn increases and the warp sheet is rubbed strongly, so that sufficient fluffing can be performed.

According to the fifth aspect, the plurality of rods are rotationally driven in directions opposite to each other, and are provided so that the rotation direction in the same direction or the opposite direction to the traveling direction of the corresponding warp sheet can be selectively set on the surface in contact with the warp sheet. Therefore, the rotation direction of the rod can be selected according to the warp type and paste type, and the optimum conditions can be set.

According to the sixth aspect of the present invention, rods are also provided in the outer regions of the warp sheets corresponding to the respective warp sheets, and the respective rods are rotationally driven at a peripheral speed lower than the traveling speed of the warp sheets and correspondingly. Since the warp sheet is in contact with the warp sheet, the warp sheet is fluffed by the rod disposed in the inner region, and is also fluffed in the outer region, thereby improving the weaving property on the loom.

FIG. 1 shows a warp gluing machine 1. The warp gluing machine 1 includes a gluing device 2 and a cylinder drying device 3 located above the gluing device 2. A large number of sheet-like warps supplied from a yarn feeder (not shown), that is, warp sheets 4 are guided to the glue liquid tank 8 of the gluing device 2 by the guide rollers 5, 6, 7 and immersed in the glue liquid 10 by the immersion roller 9. Is passed between the first sizing roller 11 and the first squeeze roller 12 facing each other in the vertical direction, and further between the pair of second sizing roller 13 and the second squeeze roller 14 disposed in the horizontal direction. The sheet is passed through while being sandwiched and appropriately glued by these gluing and squeezing processes, and then divided into two and guided to the cylinder drying device 3 disposed above the gluing device 2.

In the gluing device 2, the immersion roller 9, the first sizing roller 11, and the second sizing roller 13 are immersed in the glue liquid 10 and are driven to rotate at the same peripheral speed as the traveling speed of the warp sheet 4. The paste liquid 10 is accommodated in the paste liquid tank 8 and forms a paste liquid surface having a constant height by overflow. That is, a recovery tank 39 is provided below the paste liquid tank 8, and the paste liquid 10 in the recovery tank 39 is supplied to the paste liquid tank 8 through the circulation path by the paste liquid circulation pump 40 and recovered by overflow. It flows out into the tank 39. Thereby, the amount of the paste liquid in the paste liquid tank 8 is always maintained constant, and the paste liquid surface of the paste liquid tank 8 is maintained at a constant height. Note that the collection tank 39 is newly replenished when the paste liquid 10 is below a certain height.

The cylinder drying device 3 includes a first cylinder drying device 17 as primary drying on the upstream side in the running direction of the warp sheet 4 and a second cylinder drying device 18 as secondary drying on the downstream side in the running direction of the warp sheet 4. It is composed of The first cylinder drying device 17 has two series of drying cylinders 31 and 33 and drying cylinders 32 and 34 in order to dry each of the two warp sheets 4 separately. The drying cylinders 31 and 32 separate the warp sheet 4 into two parts by being separated from each other in a direction intersecting (orthogonal) with the surface including the warp sheet 4.

After the gluing step, the warp sheet 4 exits between the pair of second sizing rollers 13 and the second squeeze roller 14, and then alternates between the two warp sheets 4, that is, odd-numbered and even-numbered ones. Divided. One warp sheet 4 is wound around drying cylinders 31 and 33, guided to guide rollers 41 and guided to the second cylinder drying device 18, and the other warp sheet 4 is wound around drying cylinders 32 and 34. Then, it is guided to the guide roller 41 and guided to the second cylinder drying device 18. In this way, the two warp sheets 4 are divided into two, and thus are primarily dried separately under a warp interval larger than the warp interval (adjacent warp pitch) in the gluing step.

The two warp sheets 4 are merged after the primary drying, become the original warp interval, enter the secondary drying process by the second cylinder drying device 18, and come into contact with the drying cylinders 35, 36, 37, 38 It is dried again. After the primary and secondary drying, the warp sheet 4 is guided to the guide roller 41 and wound around a warp beam (not shown).

In the warp gluing machine 1 described above, the present invention is connected to the drying cylinder 31 and the drying cylinder 32 of the two systems from the gluing device 2 to the cylinder drying device 3 (first cylinder drying device 17) as a characteristic component. In the inner region of the warp sheet 4 formed between the two warp sheets 4, a plurality of, for example, two first inner rods 15 and second inner rods 16 are provided corresponding to the respective warp sheets 4. The inner rod 15 and the second inner rod 16 are rotationally driven at a peripheral speed slower than the traveling speed of the warp sheet 4 and are arranged at positions where only the corresponding warp sheet 4 is in contact, and if necessary, two warp sheets 4, the first outer rod 19 and the second outer rod 20 are arranged, and the first outer rod 19 and the second outer rod 20 are slower than the traveling speed of the warp sheet 4. It was rotated at speed, and is disposed in a position in contact with the corresponding warp sheet 4.

FIG. 2 shows the positional relationship between the first outer rod 19 and the second outer rod 20 together with the positional relationship between the first inner rod 15 and the second inner rod 16. The positions of the first inner rod 15 and the second inner rod 16 are preferably as close as possible to the second sizing roller 13 and the second squeeze roller 14 of the gluing device 2. This is because if the warp sheet 4 is separated into two parts at a stage where the drying of the glue does not proceed as much as possible, the lengths of the fluffs become uniform and the quality variation of the warp sheet 4 becomes smaller. Specifically, the positional relationship between the outer diameter D1 of the first inner rod 15 and the outer diameter D1 of the second inner rod 16 and the inter-axis distance L in the direction intersecting the traveling direction of the warp sheet 4 is expressed by the formula L ≦ ( D1 + D2) / 2 is satisfied, and the first inner rod 15 and the second inner rod 16 are arranged as close to the gluing device 2 as possible.

If it sets in this way, the 1st inner rod 15 and the 2nd inner rod 16 can be arrange | positioned near the gluing apparatus 2 in the state which contact | connected only each corresponding warp sheet 4 weakly. The first inner rod 15 and the second inner rod 16 can fluff without strongly rubbing the warp sheet 4, and thereby the lengths of the fluff are made uniform. The positions and functions of the first outer rod 19 and the second outer rod 20 will be described in detail with reference to FIG.

FIG. 3 shows a supporting portion at one end of the first inner rod 15 and the second inner rod 16. Both the first inner rod 15 and the second inner rod 16 are cylindrical, and both ends of the first inner rod 15 and the second inner rod 16 are rotatable with respect to the sintered oil-impregnated metal bearing portion of the bracket 23 serving as a bearing by a hollow shaft 22 at both ends. The bracket 24 supports the frame 24. Further, the end of the hollow shaft 22 is connected to a rotary joint 26, and the center hole thereof forms a water channel 25 for cooling liquid (cooling water). The first inner rod 15 and the second inner rod 16 are rotationally driven by obtaining a driving force from a motor (not shown) or another roller such as the second sizing roller 13 via a chain 28 and a sprocket 29. The support portions at the other ends of the first inner rod 15 and the second inner rod 16 also have the same support structure.

The cooling liquid (cooling water) enters a rotary joint 26 at one end and a water channel 25 of the shaft 22 from a cooling liquid source (cooling water source) (not shown), and is supplied to the cooling chamber 27 of the first inner rod 15 and the second inner rod 16. After cooling them, they flow out from the other end. When the coolant (cooling water) is circulated inside the first inner rod 15 and the second inner rod 16 in this way, the rod outer peripheral surface is condensed, so that the paste solution 10 attached to the rod outer peripheral surface is added with moisture. The sticking liquid 10 does not adhere directly to the rod surface, and adheres to the warp sheet 4 and is removed from the rod outer peripheral surface as the first inner rod 15 and the second inner rod 16 rotate. And less solidify.

FIG. 4 shows an example in which the first inner rod 15 and the second inner rod 16 are rotated in opposite directions and rotated in the same direction (forward direction) as the traveling direction of the corresponding warp sheet 4 on the surface in contact with the warp sheet 4. It is. In this example, the rotation of the second sizing roller 13 is opposite to the first inner rod 15 and the second inner rod 16 via the two gears 42, the sprocket 43, the chain 28, the switching sprocket 30, and the two sprockets 29. Is transmitted to. Since the first inner rod 15 and the second inner rod 16 are in contact with only the corresponding warp sheet 4, respectively, when rotated in this way, they are carried by the corresponding warp sheet 4, and the first inner rod 15 and the second inner rod 16 The fluff and paste 10 adhering to the rod 16 come into contact with the corresponding warp sheet 4 from the upstream side in the traveling direction by the rotation of the first inner rod 15 and the second inner rod 16, and transfer to the corresponding warp sheet 4. To the corresponding warp sheet 4. For this reason, it becomes difficult for the fluff and the paste liquid 10 to accumulate on the outer peripheral surfaces of the first inner rod 15 and the second inner rod 16. This effect becomes more prominent as there is no relative speed difference between the warp sheet 4 and the outer peripheral surfaces of the first inner rod 15 and the second inner rod 16. The chain 28 and the like are housed in the chain cover 44.

Next, in FIG. 5, the first inner rod 15 and the second inner rod 16 are rotated in opposite directions (reverse directions), and in the direction opposite to the traveling direction of the corresponding warp sheet 4 on the surface in contact with the warp sheet 4. This is an example of rotation. When rotated in this way, the relative speed between the outer peripheral surfaces of the first inner rod 15 and the second inner rod 16 and the warp sheet 4 increases, and the first inner rod 15 and the second inner rod 16 correspond to the corresponding warps. Since it touches the sheet 4 and rubs it strongly, a sufficient fluffing effect can be expected.

4 and 5, the rotation direction of the first inner rod 15 and the second inner rod 16 is switched by changing the mounting position of the switching sprocket 30 up and down and winding the chain 28 around the two sprockets 29. This is done by changing the hanging position. The rotation direction is selected in the optimum direction according to the warp gluing operation conditions such as the warp type, the glue type, and the traveling speed. Of course, as described above, when the first inner rod 15 and the second inner rod 16 are driven by the dedicated motor, the rotation direction of the motor, that is, the rotation direction of the first inner rod 15 and the second inner rod 16 is controlled by the selection switch. You will be able to choose.

In FIG. 6, a first outer rod 19 and a second outer rod 20 are provided corresponding to each warp sheet 4 at a position that is an outer region of the warp sheet 4 with respect to the inner region of the divided two warp sheets 4. An example is shown. In this case, the first outer rod 19 and the second outer rod 20 are rotationally driven at a peripheral speed slower than the traveling speed of the warp sheet 4 and are in contact with the corresponding warp sheet 4. In this way, the warp sheet 4 is fluffed by the first inner rod 15 and the second inner rod 16 disposed in the inner region, and also by the first outer rod 19 and the second outer rod 20 in the outer region. Since it is fluffed, weaving on the loom improves. In FIG. 6, the first outer rod 19 and the second outer rod 20 are disposed above the first inner rod 15 and the second inner rod 16 disposed in the inner region. Or both may be arranged below them. Further, by providing the first outer rod 19 and the second outer rod 20, the warp sheet 4 is bent and the inner region becomes narrow. Even in the state in which the first outer rod 19 and the second outer rod 20 are provided, the rods 15, 16, 19 so that the first inner rod 15 and the second inner rod 16 are in contact with only the corresponding warp sheet 4, respectively. , 20 are arranged.

  When the warp sheet 4 is divided into two, depending on the type of yarn, the warp sheet 4 may be shaken. Therefore, each warp sheet 4 travels while swinging, and is moved to the first inner rod 15 and the second inner rod 16. A warp sheet 4 different from the corresponding warp sheet 4 may come into contact. However, in this case, the inner rods 15 and 16 and the other warp sheet 4 are in contact with each other instead of always, so that the operation and effect of the present invention are maintained.

Since the present invention is incorporated in a process in which the warp sheet 4 is divided into two parts between the warp gluing machine and the two drying cylinders, if this incorporation condition is satisfied, the gluing method and the drying method are It is not limited to the illustrated example.
