INDUSTRIAL APPLICATION FIELD The present invention relates to a jet dyeing machine. Conventional technology Conventionally, in jet dyeing machines, cloth speed control, which affects the dyeing conditions, was done by installing a nozzle valve in front of the jet nozzle, and adjusting the opening degree of the nozzle valve while watching the nozzle pressure gauge and speed meter. It was carried out by Problems to be Solved by the Invention According to the conventional example, although it is possible to operate the nozzle valve manually or by a solenoid valve, the temperature change and temperature raising process in the dyeing machine, the constant temperature dyeing process, and the cooling process are difficult. It was difficult to adjust the jet nozzle pressure according to the dyeing conditions, and close operation was required by an expert who was familiar with the dyeing conditions. Moreover, in this case, there was a problem in that it was not possible to respond to slight changes in cloth speed due to the compatibility of the dyed object with the dye solution due to temperature changes inside the dyeing machine. Brings subtle changes in texture to fast-dyed objects,
It also affects the quality of the dyeing effect. The present invention solves the above-mentioned difficulties, prevents the initial shock at the start of the dyeing process, and improves the dyeing effect by making it possible to adjust the jet nozzle pressure according to processes such as heating process, dyeing process, and cooling process. The purpose is to Means for Solving the Problems In order to achieve the above purpose, there is a circulation path for the dyed material to be dyed while the dyed material is circulated by a liquid flow, and a dye solution for drawing out a part of the dye solution from the processing tank and sending it to the jet nozzle. A jet dyeing machine is equipped with a pump in which the jet nozzle pressure and flow rate, which determine the fabric speed, can be adjusted through a control means in the dye liquid circulation path, and the activation of the pump is controlled at the start of the dyeing process. means for preventing initial impact during the dyeing process; means for setting an optimum cloth speed value determined according to the type of material to be dyed, basis weight and other dyeing conditions; and means for detecting the actual cloth speed of the material to be dyed during the dyeing process; A jet dyeing machine characterized by sequentially performing a comparison means for calculating the difference between the detection means and the set value every moment, and a control means for adjusting or decreasing the rotation speed of the pump according to the calculated value. This method was used to control the cloth speed. Function The present invention has the above-described configuration, and has a pump that can adjust the jet nozzle pressure and flow rate that determine the cloth speed.The nozzle pressure is adjusted by controlling this pump, and dyeing is started first. A slow start can be performed to prevent the shock of time. That is, by varying the number of revolutions of the pump, the dyed material is introduced smoothly, and the temperature inside the dyeing machine and cloth speed are set to the optimum value for each process. The optimum cloth speed value is determined by data based on many years of experience by dyeing engineers, but it varies depending on the material of the object to be dyed, the basis weight, the temperature in the dyeing tank, etc. As in the present invention, these staining conditions are determined in advance by arithmetic processing of a computer that enables data processing based on the above-mentioned experience, and these staining conditions are first set. The dyeing process is started by means of setting an optimum cloth speed value selected according to the object to be dyed based on this data. Next, a detection means for measuring the actual cloth speed in the dyeing tank detects the actual value, and a comparison means calculates the difference from the set value every moment. By using a control means that adjusts or decreases the rotation speed of the pump according to this calculated value and applying feedback based on the difference between the constantly changing cloth speed and the set value, a constant cloth speed can always be obtained. Ta. Embodiment The drawings show an embodiment of the present invention, and a jet dyeing machine will be described. Although the explanation has been limited to dyeing, the present invention is of course not limited to this dyeing, and can of course be applied to processing of fabrics, ie, setting conditions for scouring, bleaching, etc. In the drawing, 1 is a processing tank, and 2 is a circulation path for the dyed material, which is connected to both ends 3, 3' of the processing tank 1.
Reference numeral 4 denotes a dye liquid circulation path, which draws out a portion of the dye liquid from the processing tank 1 and generates a jet stream from a nozzle 5 to send the dyed object 6 to the circulation path 2. 7
is a pump, which is installed in the dye solution circulation path 4 and is capable of controlling the nozzle pressure and flow rate of the nozzle 5. The rotation speed of the pump 7 can be changed by an inverter 8, and the inverter 8 is controlled by the output of a central processing unit (CPU) 9. A cloth speed detector 10 detects and feeds the actual cloth speed from moment to moment to the central processing unit 9, while a cloth speed setting portion 11 calculates in advance the optimum cloth speed value based on the type of material to be dyed, the basis weight, etc. is configured so that the setting value is sent. The central processing unit 9 compares the actual value and the set value, calculates the difference value, and controls the rotational speed of the pump 7 via the inverter 8. Above 8,
9 and 11 serve as control means. With the above-mentioned configuration, in the embodiment of the present invention, the cloth speed is detected from the cloth speed detection unit 10 every moment, and the increase or decrease in the rotation speed of the pump 7 due to the difference from the optimum setting value is controlled via the central processing unit 9. This has made it possible to always obtain optimal conditions. Although the fabric speed detection unit 10 is shown as an example provided in the reel part in the drawing, it is not limited to this, for example, a detectable magnetic substance may be attached to a roll part instead of the reel, or even to the object to be dyed. This can also be done by detecting its passing speed.

も可能となる等種々の効果を有する。[Table] The table above shows examples of cloth speed and nozzle pressure depending on the product name, material, basis weight, etc. of the cloth. Much of this data is stored in the cloth speed setting section 11 and sent to the central processing unit. It can be stored or sent again. With the above configuration, it is possible to control the cloth speed by automatically controlling the nozzle 5 pressure and the pump 7 rotation speed. Therefore, there is no need to operate the nozzle valve as in the conventional case. Moreover, automatic adjustment of nozzle pressure during the dyeing process is possible. That is, by comparing the reel rotation speed and the cloth speed setting value, the pump rotation speed can be automatically adjusted so that the reel rotation speed becomes the set value. In addition, since the pump starts smoothly at the start of the dyeing process and prevents a sudden initial impact, a slow start is now possible. This also eliminates defects such as eye blur. Furthermore, in the embodiment of the present invention, the nozzle pressure can also be controlled to be switched by temperature setting.
That is, the fabric speed varies slightly depending on the temperature difference, and this is thought to be because the state of compatibility between the fabric and the dye liquor changes depending on the temperature. Therefore, if the temperature is, for example, 70℃ or less, 2.0Kg/c
m 2 nozzle pressure, and if the temperature exceeds 70℃, 1.5
Kg/cm 2 can be controlled via the central processing unit. In addition, by constantly sending the actual value from the fabric speed detection unit to the central processing unit to adjust the nozzle pressure based on the temperature difference, the pump rotation speed can be controlled based on momentary changes, making it possible to make stepless adjustments based on temperature changes. did. Effects of the Invention As described above, the present invention first prevents the initial impact caused by the processing liquid when introducing the dyed material into the dyeing machine, and then provides the optimal Setting the cloth speed setting value and detecting the actual cloth speed value, comparing the two to find the difference, and feeding this back to the control of the pump that fluctuates the nozzle pressure and flow rate via the central processing unit. This makes it possible to automatically maintain a constant cloth speed. Therefore, it is no longer necessary for a skilled person to operate the nozzle valve as in the conventional example. In addition, since the pump is controlled based on the difference between the set value and the actual value, it operates only when necessary, enabling power-saving operation. In addition, by setting the initial pump drive to a slow start to alleviate the sudden impact of the jet stream at the beginning of the dyeing process, it has become possible to eliminate defects such as eye blurring. In addition, since the detection is carried out continuously during the dyeing process operation and the feedback is sent to the control unit, the cloth speed can be constantly monitored and maintained at a constant cloth speed, and a fully automatic control system can be realized by linking with a computer system. It has various effects.
