Abstract

(57) [Abstract] [Purpose] To obtain a dehumidifying device that improves the dehumidifying efficiency of the draft portion of a spinning machine and prevents wrap-up. [Structure] A main duct provided with a branch pipe opening toward a draft portion is provided in a longitudinal direction of a frame of a spinning machine, and dry air is sent through the main duct and the branch pipe.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a dehumidifying device for a spinning machine.

[0002]

[Prior Art]

 Currently, when dehumidifying a spinning machine, the entire room is dehumidified by a fixed dehumidifier installed in the spinning room. Therefore, the dehumidification efficiency was poor and it was not possible to completely prevent wrap-up.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to obtain a dehumidifying device capable of improving the dehumidifying efficiency of the draft portion of the spinning machine and preventing wrap-up.

[0004]

[Means for Solving the Problems]

 A main duct equipped with a branch pipe that opens toward the draft section was provided in the longitudinal direction of the frame of the spinning machine, and dry air was sent through the main duct and the branch pipe.

[0005]

[Action]

 Dry air is blown directly to the draft section of the spinning machine to dry the draft section and prevent sliver wrap-up.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

A spinning machine 1 embodying the present invention includes a back roller 4a, a middle roller 4b, a front roller 4a for drafting a sliver S sent through a trumpet guide 3 on a frame 2 of the spinning machine 1. 4c, a drafting device 4 composed of 4c, an air spinning nozzle 5 for twisting the drafted sliver fed from the front roller 4c, a feeding roller 6 for feeding the twisted yarn Y, and a package 7 for feeding the fed yarn. A winding device 8 for winding the sliver S is provided on the back side of the spinning device 1, and a creel device 10 for supplying the sliver S in the can 9 to the trumpet guide 3 is provided.

Reference numeral 11 denotes a main duct that extends on the frame 2 of the spinning machine 1 over the entire length in the longitudinal direction. The main duct 11 includes the draft devices 4 that branch from the main duct 11 and are arranged in parallel on the spinning machine. A branch pipe 12 that opens downward is provided. Then, one end of the main duct 11 is connected to a supply source (not shown) of dehumidified dry air, and the dry air sent into the main duct 11 is blown out from below the respective draft devices 4 through the branch pipes 12, The periphery of the drafting device 4 is made dry and the sliver being drafted is prevented from being wrapped up.

The branch pipe 12 branched from the main duct 11 is not limited to the one that is opened only at the intermediate position between the back roller 4a and the middle roller 4b and below the front roller 4c as shown in FIG. It does not matter as long as dry air can be blown from below the draft device 4 over all parts of the draft device 4, and various forms other than those shown can be used.

Next, in the second embodiment shown in FIG. 2, in addition to the dehumidifying main duct 11 and the dehumidifying branch pipe 12, a humidifying main duct 13 and a humidifying branch pipe 14 are provided. A humidity sensor 15 is provided near each draft device 4, and the humidity value detected by the sensor is sent to a control device 16 provided at the end of the machine base. From the controller 16, a control signal corresponding to the humidity value is sent to the dehumidifying electromagnetic valve 17 and the humidifying electromagnetic valve 18 provided for each dehumidifying branch pipe 12 and each humidifying branch pipe 14, The valves 17 and 18 are adapted to open and close based on the above signals. According to this embodiment, proper humidification / dehumidification is performed according to the humidity in the vicinity of each draft device 4, and the humidity in the vicinity of each draft device 4 can be maintained at a good humidity (40 to 60%) for spinning. it can.

[0011]

[Effect of the device]

 As described in detail above, the present invention has a configuration in which a main duct having a branch pipe opening toward a draft portion is provided in the machine longitudinal direction of a spinning machine, and dry air is sent through the main duct and the branch pipe. Therefore, it is possible to blow dry air from below each draft device on the spinning machine, and as a result, there is no need to dehumidify the entire spinning chamber as in the past, and much more efficient operation of the vicinity of the draft device. It was possible to prevent the occurrence of wrap-up by drying, and it was possible to obtain various effects such as improved dehumidification efficiency, energy conservation, and productivity improvement.
