Description

[Detailed description of the invention]

(Industrial Application Field) The present invention is a method of washing carpets while feeding connected long textile products such as knitted fabrics made of natural fibers, synthetic fibers, chemical fibers, etc. in a rope-shaped bundle. , relates to a continuous processing machine that continuously performs processing such as washing, dyeing, scouring, and bleaching.More specifically, it expands the range of products that can be processed by this continuous processing machine, and can also be applied to a wide range of textile products. The present invention relates to a continuous processing machine for textile products that provides excellent processing effects and can easily carry out continuous loop length correction. (Prior art) Conventionally, in the process of processing textile products in a rope-shaped bundle, the textile products connected in an endless manner are repeatedly passed between a processing liquid and a squeezing roller. Batch-type processing machines are used, but due to their structure, productivity is low,
Inefficiency is a major drawback. Further, in order to improve productivity, a system in which a large number of processing machines are connected increases the installation area and is not practical. Therefore, a device that solves the above-mentioned problems with the processing machine, that is, one that makes it possible to continuously perform processing liquid impregnation and squeezing several hundred times with one processing machine, without increasing the installation area. This method has been proposed in Japanese Patent Application Laid-Open No. 51-47189. An outline of the mechanism of this processor will be explained based on FIG. In the figure, 1 is a processing chamber that stores processing liquid;
Above the processing chamber 1, a squeezing roller 2 consisting of a top roller 2a and a bottom roller 2b is disposed in a vertically opposed state. The squeezing roller 2
The top roller 2a is pressurized and pressed onto the bottom roller 2b, and the bottom roller 2b is actively rotated by a drive device (not shown) capable of forward and reverse rotation. It's summery. However, in this squeezing roller 2, the amount of feed of the textile product 3 when rotating in the forward direction (forward direction A) is larger than the amount of feed of the textile product 3 when rotating in the reverse direction (backward direction B). Guide rollers 4a and 4b, which rotate in the forward and reverse directions together with the liquid squeezing roller 2, are arranged before and after the liquid squeezing roller 2. When the liquid squeezing roller 2 rotates in the forward direction, one guide roller 4a is provided. is actively rotated as a take-up roller, and the other guide roller 4b is passively rotated,
When the squeezing roller 2 reverses, the situation is reversed, that is, the guide roller 4b acts as a take-up roller. Although such a configuration enables efficient continuous processing, there is always some slippage between the squeezing roller and the textile product, and the fluctuations in the loop length caused by this will cause problems during long-term processing. Problems such as tangles of textile products inside the machine and wrapping around the squeezing rollers are occurring. The loop length correction work that is required in such cases is extremely complicated manual work, and a device has been developed to overcome this problem and carry out accurate loop length correction continuously, which has already been proposed in Japanese Patent Publication No. 12384/1984. ing. The outline of this apparatus will be explained based on an example shown in FIG. is provided, and when a detection device for detecting excessive tension or slack provided in the feeding path of the textile product 3 detects the detection object, the machine is stopped and the squeezing roller 2 and the guide roller 4 are stopped. It has a mechanism to stop it. After stopping the machine, lift the top roller 2a of the liquid squeezing roller 2 and remove the bottom roller 2.
b (dotted line) to bring it into an inoperable state, and then grip the corresponding part of the textile product 3 with the gripping lever 5 and pull it away from the guide roller 4 (dotted line) to restart the machine. As a result, the portion of the textile product 3 that has been separated from the guide roller 4 comes to a halt, and the loop lengths before and after it are corrected. After the correction is completed, the grip on the textile product 3 is released and the top roller 2a is returned to its original position to resume normal operation. However, by providing the above-mentioned loop length correction device, accurate and simple loop length correction can be performed, and continuous processing can be performed with even greater efficiency. (Problems to be Solved by the Invention) Although the above-mentioned continuous processing machine has an extremely excellent effect in terms of efficient processing, it may cause wrinkles and operational difficulties depending on the products to be processed. Issues such as gender could not be avoided. That is, in this continuous processing machine, since the textile product is reciprocated by the above-mentioned mechanism, wrinkles are less likely to form compared to the batch-type processing machine, but wrinkles may still occur depending on the type of textile product. The problem even affected the quality of the images. That is, in this continuous processing machine, the top roller load is set from its own weight to the pressure side, and the load can be selected depending on the textile product to be processed. In other words, in this pressurizing method, the roller's own weight is the minimum, and at least the roller's own weight is applied to any textile product. However, depending on the type of textile product, wrinkles may occur due to the application of pressure alone, making it necessary to limit the types of textile products to be treated. In addition, since conventional batch processing machines are equipped with a mechanism that allows the roller pressure to be set freely from negative to positive, this continuous processing machine is also equipped with a similar mechanism to adjust the roller pressure depending on the type of product being processed. If it were possible to do so, it would be possible to prevent the occurrence of wrinkles, but on the other hand, it would be unsuitable due to problems when performing loop length correction work. In other words, if the roller pressure is set to a negative value in order to prevent wrinkles in the textile product to be processed, it will be impossible to raise the top roller sufficiently during the loop length straightening work mentioned above, and the result will be damage to the textile product to be processed. It was inevitable that the types would be limited. In other words, in order to protect the processed product from wrinkles and to obtain a sufficient texture, it is necessary to set the optimal roller pressure for each type of product, and then perform corrections such as loop length correction. There were times when it was impossible to carry out the work due to the reasons mentioned above. The present invention was developed in view of the above circumstances, and it allows the roller pressure to be freely set from positive to negative regardless of the type of textile product to be processed. The object of the present invention is to provide a continuous processing machine for textile products in which the raising and lowering of rollers can be carried out smoothly without any problem. (Means for Solving the Problems) In order to achieve the above object, the continuous processing machine for textile products of the present invention has the following configuration.
That is, a processing chamber provided in a textile product feeding route,
A rotatable liquid squeezing roller consisting of a top roller and a bottom roller arranged vertically opposite each other above the processing chamber, a rotatable guide roller provided before and after the liquid squeezing roller, and a rotatable liquid squeezing roller provided on the guide roller. The continuous fiber product introduced from one end side of the processing chamber is passed through the squeezing roller and the guide roller to form a plurality of loops and set in a spiral shape. In a continuous processing machine for textile products configured to lead out from the other end, the top roller is provided with an air cylinder for raising and lowering it, and two air pressure supply means are connected in parallel to the air cylinder. One of the two air pressure supply means is for setting the top roller load during normal operation, and the other is for raising the top roller during the loop length correction operation by the loop length correction device, and the loop The gist of the present invention is to include a switching means for switching between the two supply means at the start and end of the length straightening operation. (Function) By adopting such a configuration, during normal operation, pressure is supplied from the air pressure supply means side for setting the top roller load, so that the optimum load can be applied to the textile products to be processed, that is, the textile products can be Depending on the type, by setting the load on the textile product lower than that due to the roller's own weight, it is possible to prevent wrinkles from forming in the textile product during processing. Furthermore, when the loop length correction device performs a loop length correction operation, the top roller is smoothly raised and the loop length is corrected by switching from the top roller load setting to the top roller raising air pressure supply means. becomes possible. In other words, no matter what type of textile product is selected, it is possible to eliminate problems such as wrinkles and achieve continuous loop length correction. Hereinafter, embodiments of the present invention will be described in detail based on the drawings. (Embodiment) FIG. 2 is an air circuit diagram showing an embodiment of the continuous processing machine for textile products of the present invention. The processing type of the continuous processing machine shown in this air circuit diagram is the same as the above-mentioned type shown in FIG.
The textile product passing between the squeezing rollers 2 is continuously processed while rotating the squeezing rollers 2 consisting of the squeezing rollers 2 in forward and reverse directions. However, the squeezing roller 2
By making the feed rate of the textile product by normal rotation (forward direction) larger than the feed rate of the textile product by reverse rotation (backward direction), the process liquid and the squeezing liquid roller 2 are mixed while moving the textile product forward and backward. The mechanism is such that it passes through the space repeatedly. In this continuous processing machine, the textile products to be processed are spirally arranged to form multiple loops.
Slips and the like of the textile products that occur during this process lead to fluctuations in the loop length, which sometimes causes problems such as tangles and damage to the textile products. In order to eliminate such an undesirable problem, it is necessary to correct the loop length as appropriate, but when correcting the loop length, the top roller 2a of the squeezing roller 2 is raised as described above based on FIG. It is necessary to separate it from the bottom roller 2b. However, in this embodiment, known air cylinders 6 are provided at both ends of the top roller 2a as a mechanism for raising and lowering the top roller 2a. The supply pressure passage to the air cylinder 6 is from the air cylinder 6 through the electromagnetic switching valve 7.
Two air pressure reducing valves 8 connected in a bifurcated manner
a and 8b, and the configuration is such that the signals are selectively supplied. The air pressure reducing valves 8a and 8b are
It has electromagnetic on-off valves 9a and 9b connected to each other as switching means for switching these 8a and 8b, and the electromagnetic on-off valves 9
The set pressure in either of the air pressure reducing valves 8a, 8b connected thereto is supplied to the air cylinder 6 via either one of the air cylinders a and 9b. The air pressure reducing valves 8a and 8b serve to always supply air at a constant pressure without being affected by changes in pressure on the supply side and air consumption on the load side, and can be selected from various known techniques and used. good. However, the set pressure in one of the two air pressure reducing valves 8a and 8b, for example 8b, is set to an air pressure that is sufficient to raise the top roller 2a, and the other pressure reducing valve 8a is set at a pressure that is sufficient to raise the top roller 2a. Then, set the air pressure appropriately to obtain the optimal roller load. That is, during normal operation, the air pressure set in the pressure reducing valve 8a is sent out by opening the electromagnetic on-off valve 9a connected to the pressure reducing valve 8a, and the air is sent out via the electromagnetic switching valve 7 connected to the piston rod of the air cylinder 6. By supplying it to the cylinder 6, the load on the top roller 2a is optimized for the processed product. In addition, when it becomes necessary to correct the loop length during operation and the machine is stopped and the top roller 2a is raised, the electromagnetic on-off valve 9b is simultaneously closed by the sent electric signal and the electromagnetic on-off valve 9b is opened to reduce the pressure. The mechanism is such that the air pressure set in the valve 8b is sent out and supplied to the air cylinder 6 via the electromagnetic switching valve 7 to raise the top roller 2a. Although the air cylinder 6 connected to the top roller 2a can be selected from various types, it is preferable to use a double-acting cylinder in consideration of raising and lowering the top roller 2a.
That is, the operation section that moves the top roller 2a up and down uses a double-acting cylinder that operates in both reciprocating and reciprocating directions and that operates by alternating the inlet and outlet of air pressure. Then, the inlet/outlet is appropriately selected via the electromagnetic switching valve 7,
This is to raise and lower the top roller 2a. According to such a mechanism, the top roller 2a
When processing textile products that wrinkle due to their own weight alone, it is possible to select reduced pressure instead of roller pressure. In the continuous processing machine actually in operation, the roller pressure was set to the pressure reduction side, and the load per loop of the textile product at that time was measured, and the results are shown in the table below. The weight of the top roller 2a of the processing machine used in this example is 1050 kg.

[Table] As shown in the table above, the load per loop can be freely changed as the vacuum gauge pressure changes. Further, it goes without saying that adjustments other than those shown in the above table are also possible. On the other hand, in order to raise the top roller 2a sufficiently during loop length correction work, it is necessary to use a weight of 1050 kg.
It was necessary to set the pressure of the air pressure reducing valve on the roller to at least 3 kg/cm ² . This setting value may be set to a necessary value depending on the roller's own weight. In other words, depending on the product being processed, the set pressure may be set to, for example, 0.5 kg/
Even when the loop length is about cm ² , pressure is supplied from a pressure reducing valve that is set to raise the air pressure for raising the top roller 2a during loop length correction work, so the raising of the top roller 2a can be carried out smoothly without any problem. (Effects of the Invention) As described above, the continuous processing machine for textile products of the present invention can freely set the optimal roller pressure for any type of textile product from positive to negative, thereby preventing the occurrence of wrinkles. In addition to preventing this, it also makes it possible to raise the top roller during loop length correction work in a continuous process.
It has excellent effects and performs efficient and high-quality continuous processing on an extremely wide range of textile products.
