Technical Field
The invention relates to an electromagnetic valve unit and an automatic winder.
Background
For example, japanese patent application laid-open No. 2001-106434 describes a pipe joint for detachably joining a plurality of air pipes. The pipe joint described in jp 2001-106434 a includes an opening/closing piece formed of a shaft valve body or the like, and a valve operating member formed of a rod or the like. In the pipe joint described in japanese patent application laid-open No. 2001-106434, a plurality of air paths are opened and closed simultaneously by operation of a valve operating element.
Disclosure of Invention
In the above-described conventional technology, for example, there is a case where it is desired to selectively switch and output an air circuit of one of the air of the two systems.
In such a case, various valves, air pipes and air joints for connecting them, and the like are required, and a large amount of resources (cost, space, man-hours for assembly, and the like) are required.
The invention aims to provide an electromagnetic valve unit and an automatic winder, which can reduce required resources.
The electromagnetic valve unit of the present invention includes: a housing which includes a 1 st flow path through which a 1 st air flows, a 2 nd flow path through which a 2 nd air having a higher pressure than the 1 st air flows, and a 3 rd flow path connected to a downstream side of the 1 st flow path and a downstream side of the 2 nd flow path via a shuttle valve; a 1 st electromagnetic valve integrated with the housing and controlling the flow of 1 st air to the 1 st flow path; and a 2 nd electromagnetic valve, the 2 nd electromagnetic valve is integrated with the outer casing, control the circulation of the 2 nd air to the 2 nd flow path, there is the 1 st outfall that is supplied to any one in the 1 st air and 2 nd air circulating in the 3 rd flow path that flows out on the outer casing.
In this solenoid valve unit, the 1 st and 2 nd solenoid valves and the housing are integrated, whereby a desired air circuit as described above (i.e., an air circuit capable of selectively switching between and outputting one of the two systems of air input thereto) can be realized. This can reduce space, air tubes and air joints, and reduce assembly man-hours, for example. Thus, a reduction in required resources can be achieved.
In the solenoid valve unit according to the present invention, the housing may further include a 4 th flow path connected to the 2 nd flow path inside the housing, and the housing may be provided with a 2 nd outlet through which the 2 nd air flowing through the 4 th flow path flows out. This makes it possible to provide a system for directly outputting the 2 nd air of high pressure.
In the solenoid valve unit according to the present invention, the 1 st outflow port and the 2 nd outflow port may be provided on the same surface in the housing. This makes it possible to easily perform pipe replacement when air is supplied to the external device through the solenoid valve unit.
In the solenoid valve unit according to the present invention, the 1 st solenoid valve may be a normally open type solenoid valve that allows the flow of the 1 st air when not energized, and the 2 nd solenoid valve may be a normally closed type solenoid valve that blocks the flow of the 2 nd air when not energized. Thus, for example, when the 1 st solenoid valve and the 2 nd solenoid valve are not energized during a power failure, the 1 st air at a lower pressure than the 2 nd air is output. The safety can be improved.
The solenoid valve unit of the present invention may include a 1 st inlet through which the 1 st air flows and a 2 nd inlet through which the 2 nd air flows, wherein the 1 st inlet is provided in the 1 st solenoid valve, the 2 nd inlet is provided in the housing, and the housing further includes a 5 th flow path inside the housing through which the 2 nd air flows from the 2 nd inlet to the 2 nd solenoid valve. With this configuration, the 1 st air and the 2 nd air can be specifically input to the solenoid valve unit.
An automatic winder of the present invention includes: a holding section that sandwiches and holds the package; a brake unit that controls a holding force and braking of the holding unit according to a pressure of the supplied air; and the electromagnetic valve unit, wherein when the package is held by the brake section and the holding section so that the package can rotate, the electromagnetic valve unit opens the 1 st electromagnetic valve and closes the 2 nd electromagnetic valve, and supplies the 1 st air to the brake section through the 1 st outlet port, and when the package is braked by the brake section and the holding section, the electromagnetic valve unit opens the 2 nd electromagnetic valve and supplies the 2 nd air to the brake section through the 1 st outlet port.
In the automatic winder, the solenoid valve unit can realize an air circuit for rotatably holding and braking the package, and can reduce necessary resources in addition to realizing the air circuit.
According to the present invention, it is possible to provide an electromagnetic valve unit and an automatic winder that can reduce necessary resources.

Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and redundant description thereof is omitted.
As shown in fig. 1, the automatic winder 1 includes a plurality of winder units 3 arranged in an array, a machine base control device 5, and a doffing device 7. The machine station control device 5 can communicate with the plurality of winder units 3, respectively. The operator of the automatic winder 1 can collectively manage the plurality of winder units 3 by appropriately operating the machine station control device 5. Each winder unit 3 unwinds the spun yarn Y from the yarn supplying bobbin SB and winds the spun yarn Y onto the winding bobbin WB while traversing, thereby forming a package P. When the package P becomes a full package (a state in which a predetermined amount of yarn is wound) in each winder unit 3, the doffer 7 moves to the position of the winder unit 3, removes the full package, and sets an empty winding bobbin WB.
As shown in fig. 2, the winder unit 3 includes a unit control unit 10, a yarn feeding device 12, and a winding device 14. The Unit control Unit 10 includes, for example, a CPU (Central Processing Unit) and a ROM (Read Only Memory). The ROM stores programs for controlling the respective configurations of the winder unit 3. The CPU executes programs stored in the ROM.
The yarn supplying device 12 supports a yarn supplying bobbin SB placed on a not-shown conveyance tray at a predetermined position. The yarn feeding device 12 unwinds the spun yarn Y from the yarn feeding bobbin SB and draws the spun yarn Y from the yarn feeding bobbin SB. The yarn feeding device 12 feeds the spun yarn Y. The yarn feeding device 12 is not limited to a tray type device, and may be a magazine type device, for example.
The winding device 14 includes a cradle 16 and a winding drum 18. The cradle 16 sandwiches the winding bobbin WB by winding bobbin holding portions (holding portions) 19a and 19b (see fig. 3), thereby rotatably supporting the winding bobbin WB (or the package P). The cradle 16 can be switched between a state in which the package P is in contact with the winding drum 18 and a state in which the package P is separated from the winding drum 18 (lifted state) by a lift cylinder 57 described later.
The winding drum 18 traverses the spun yarn Y on the surface of the package P and rotates the package P. The winding drum 18 is rotationally driven by a drum driving motor, not shown. The winding drum 18 is rotationally driven in a state where the outer periphery of the package P is in contact with the winding drum 18, thereby rotationally driving the package P. A spiral traverse groove is formed in the outer peripheral surface of the winding drum 18. The spun yarn Y unwound from the yarn supplying bobbin SB is wound on the surface of the package P while being traversed at a constant width by the traverse groove. This enables the formation of the package P having a fixed web.
Each winder unit 3 includes, in order from the yarn feeding device 12 side, an unwinding assisting device 20, a tension applying device 22, a tension detecting device 24, a yarn splicing device 26, and a yarn monitoring device 28 in a yarn running path between the yarn feeding device 12 and the winding device 14. In the vicinity of the yarn joining device 26, a 1 st catching guide device 30 and a 2 nd catching guide device 32 are arranged.
The unwinding assisting device 20 prevents the spun yarn Y unwound from the yarn supplying bobbin SB from being excessively swung open by centrifugal force, and properly unwinds the spun yarn Y from the yarn supplying bobbin SB. The tension applying device 22 applies a prescribed tension to the running textile yarn Y. In the present embodiment, the tension applying device 22 is a gate type device in which movable comb teeth are arranged with respect to fixed comb teeth.
The tension detecting device 24 detects the tension of the advancing spun yarn Y between the yarn feeding device 12 and the winding device 14. The yarn joining device 26 joins the spun yarn Y (lower yarn) on the side of the yarn supplying device 12 and the spun yarn Y (upper yarn) on the side of the winding device 14 when the spun yarn Y is in a cut state for some reason between the yarn supplying device 12 and the winding device 14.
The yarn monitoring device 28 monitors the state of the spun yarn Y running on the yarn path, and detects the presence or absence of a yarn defect based on the monitored information. The yarn defect is at least one of an abnormal thickness of the spun yarn Y, a foreign substance contained in the spun yarn Y, and a yarn breakage, for example.
The 1 st catching guide 30 is rotatable from a standby position on the yarn feeding device 12 side to a catching position on the winding device 14 side. The 1 st catching guide 30 catches the upper yarn at the catching position and guides it to the yarn splicing device 26. The 2 nd catching guide 32 is rotatable from a standby position on the yarn feeding device 12 side to a catching position on the winding device 14 side. The 2 nd catching guide 32 catches the lower yarn and guides it to the yarn splicing device 26.
As shown in fig. 3, the cradle 16 is a member for gripping the package P, and includes a pair of cradle arms 16a and 16 b. The rocker arms 16a, 16b are supported rotatably about a hinge shaft. The rocker arms 16a, 16b can rotate in a direction toward and away from the winding drum 18.
Winding bobbin holding portions 19a and 19b are rotatably attached to the distal ends of the cradle arms 16a and 16b, respectively. The winding bobbin holding portions 19a and 19b are arranged to face each other. The winding bobbin holding portions 19a and 19b constitute holding portions that sandwich and hold the package P. When the winding bobbin WB is attached to the cradle 16, the winding bobbin holding portions 19a and 19b are fitted into the axial end portions of the winding bobbin WB, and they are integrally rotated by friction.
As shown in fig. 4, a package stopper 51 is provided at the tip end of the cradle arm 16 a. The package brake 51 constitutes a braking section for controlling the holding force and braking by the winding bobbin holding sections 19a and 19b in accordance with the pressure of the supplied air. The package brake 51 includes a housing 52, a bearing sleeve 53, a rotation support portion 54, a 1 st spring 55, and a 2 nd spring 56.
The bearing sleeve 53 is provided movably but non-rotatably with respect to the housing 52. The rotation support portion 54 is provided inside the bearing sleeve 53, and rotatably supports a shaft extending from the winding bobbin holding portion 19 a. The 1 st spring 55 is disposed between the bottom surface of the housing 52 and the bearing sleeve 53. The 1 st spring 55 applies a biasing force to the bearing sleeve 53 toward the winding bobbin holding portion 19 a. The 2 nd spring 56 is disposed between the bearing sleeve 53 and the rotation support portion 54. In this configuration, the winding bobbin holding portion 19a can freely rotate relative to the bearing sleeve 53 in a state where air is not supplied to the housing 52.
On the other hand, when air is supplied into the housing 52, the contact portion 53a provided in the bearing sleeve 53 contacts the winding bobbin holding portion 19a in accordance with the pressure of the air. At this time, since the winding bobbin holding portion 19a is sandwiched between the winding bobbin WB and the bearing sleeve 53, frictional resistance is generated between the winding bobbin holding portion 19a and the contact portion 53 a. Accordingly, the rotation of the winding bobbin holding portion 19a is braked, and the rotation of the winding bobbin WB (and the package P) can be braked. Further, since the winding bobbin holding portion 19a is strongly pressed into the axial end portion of the winding bobbin WB due to the entry of the bearing sleeve 53, the frictional engagement between the winding bobbin holding portion 19a and the winding bobbin WB is strengthened, and the winding bobbin WB is less likely to slip relative to the winding bobbin holding portion 19 a. In this manner, the package brake (braking portion) 51 is configured to simultaneously brake the rotation of the winding bobbin holding portion 19a and press the winding bobbin holding portion 19a toward the winding bobbin WB.
When the 1 st air is supplied, the force applied to the bearing sleeve 53 by the package brake 51 is equal to or greater than a predetermined value and less than a predetermined value. The 1 st air is, for example, compressed air having a pressure of 0.1 to 0.2 MPa. In this case, although the force for clamping the winding bobbin WB between the winding bobbin holding portions 19a and 19b is increased, the rotation of the winding bobbin WB is not braked. However, the specification does not require the 1 st air, depending on the specification. In this case, the pressure of the 1 st air can be set to 0 MPa.
On the other hand, when the 2 nd air having a higher pressure than the 1 st air is supplied to the package brake 51, the force acting on the bearing sleeve 53 becomes equal to or greater than the predetermined value. The No. 2 air is, for example, compressed air having a pressure of 0.3 to 0.7 MPa. In this case, the rotation of the winding bobbin WB is braked. Specifically, the bearing sleeve 53 frictionally engages with the winding bobbin holding portion 19a, and relative rotation between the two is stopped.
A piston rod of a lift cylinder 57 shown in fig. 5 is connected to the cradle arm 16 a. The lift cylinder 57 is a device for moving the cradle 16 to separate the package P from the winding drum 18. The lift cylinder 57 is driven by being supplied with the 2 nd air. The cradle 16 can be rotated in a direction to separate the package P from the winding drum 18 by the extension driving of the lift cylinder 57.
In the present embodiment, each winder unit 3 of the automatic winder 1 includes the solenoid valve unit 100 shown in fig. 5, 6, and 7. The solenoid valve unit 100 is a unit that can selectively switch and output one of the two systems of air. Specifically, the solenoid valve unit 100 is a unit constituting an air circuit capable of selectively switching and outputting one of the two systems of air and capable of directly outputting one of the two systems of air. More specifically, the solenoid valve unit 100 outputs the 1 st air when the 1 st air is inputted, and outputs the 2 nd air instead of the 1 st air and further outputs the 2 nd air as it is when the 2 nd air is further inputted in addition to the 1 st air.
The solenoid valve unit 100 includes a housing 110, a 1 st solenoid valve 120, and a 2 nd solenoid valve 130. The housing 110 is formed of fiber reinforced plastic containing glass fibers. The casing 110 includes a 1 st channel 111, a 2 nd channel 112, a 3 rd channel 113, a 4 th channel 114, and a 5 th channel 115 therein. The 1 st to 5 th channels 111 to 115 are, for example, holes formed in the casing 110.
The 1 st flow path 111 is a flow path through which the 1 st air output from the 1 st solenoid valve 120 flows. The 1 st flow path 11 is connected to an outlet port of the 1 st solenoid valve 120. The 2 nd flow path 112 is a flow path through which the 2 nd air output from the 2 nd solenoid valve 130 flows. The 2 nd flow path 112 is connected to an outlet port of the 2 nd solenoid valve 130. The 3 rd flow path 113 is connected to the downstream side of the 1 st flow path 111 and the downstream side of the 2 nd flow path 112 via the shuttle valve 140. The 3 rd flow path 113 is a flow path through which either the 1 st air or the 2 nd air flows.
The 4 th channel 114 is connected to the middle of the 2 nd channel 112. The 4 th flow path 114 is a flow path through which a part of the 2 nd air flowing through the 2 nd flow path 112 flows. The 5 th flow path 115 is a flow path through which the 2 nd air flows from a 2 nd input air coupling (air) 160 to be described later to the 2 nd solenoid valve 130. The 5 th flow path 115 is connected to an inlet port of the 2 nd solenoid valve 130.
The shuttle valve 140 includes an inlet communicating with the 1 st flow path 111, an inlet communicating with the 2 nd flow path 112, and an outlet communicating with the 3 rd flow path 113. The shuttle valve 140 is a valve in which an inlet on the high pressure side of the two inlets is connected to an outlet. The shuttle valve 140 outputs the 1 st air to the 3 rd flow path 113 in a state where the 1 st air is input from the 1 st flow path 111 and the 2 nd air is not input from the 2 nd flow path 112. The shuttle valve 140 outputs the 2 nd air of the high pressure side to the 3 rd flow path 113 in a state where the 1 st air is input from the 1 st flow path 111 and the 2 nd air is input from the 2 nd flow path 112.
The 1 st electromagnetic valve 120 controls the flow of the 1 st air to the 1 st flow path 111. Specifically, the 1 st electromagnetic valve 120 allows and blocks the 1 st air to flow through the 1 st flow path 111. The 1 st solenoid valve 120 is a normally open type solenoid valve that allows the 1 st air to flow therethrough when not energized. The 1 st electromagnetic valve 120 includes an electromagnetic element portion and a valve portion. The 1 st electromagnetic valve 120 is not particularly limited, and various known electromagnetic valves can be used. The 1 st solenoid valve 120 is integrated with the housing 110. The term "integrated" in the present embodiment includes physically integrated and mixed with each other (the same applies hereinafter). For example, a part of the 1 st solenoid valve 120 is formed by the housing 110. The function of the 1 st solenoid valve 120 is established due to the presence of the housing 110.
The 2 nd solenoid valve 130 controls the flow of the 2 nd air to the 2 nd flow path 112. Specifically, the 2 nd solenoid valve 130 allows and blocks the flow of the 2 nd air to the 2 nd flow path 112. The 2 nd solenoid valve 130 is a normally closed solenoid valve that shuts off the flow of the 2 nd air when not energized. The 2 nd solenoid valve 130 includes a solenoid portion and a valve portion. The 2 nd solenoid valve 130 is not particularly limited, and various known solenoid valves can be used. The 2 nd solenoid valve 130 is integrated with the housing 110. For example, a part of the 2 nd solenoid valve 130 is constituted by the housing 110. The function of the 2 nd solenoid valve 130 is established due to the presence of the housing 110. The 1 st solenoid valve 120 and the 2 nd solenoid valve 130 are disposed in close proximity.
The solenoid valve unit 100 includes a 1 st input air coupler 150, a 2 nd input air coupler 160, a 1 st output air coupler 170, and a 2 nd output air coupler 180. The 1 st input air coupler 150 constitutes a 1 st inlet into which the 1 st air flows. The 1 st input air coupler 150 (1 st inlet port) is provided on the side surface of the 1 st solenoid valve 120. The 1 st input air coupler 150 is connected to an inlet port of the 1 st solenoid valve 120. The 2 nd input air coupler 160 constitutes a 2 nd inlet into which the 2 nd air flows. The 2 nd input air coupler (2 nd inlet port) 160 is provided on the side surface 110a of the casing 110. The 2 nd inlet air coupler 160 is connected to the upstream side of the 5 th flow path 115.
The 1 st output air coupler 170 constitutes a 1 st outlet through which one of the 1 st air and the 2 nd air flowing through the 3 rd flow path 113 flows out. The 1 st output air coupler 170 (1 st outflow port) is provided on the side surface 110b of the casing 110 opposite to the side surface 110 a. The 1 st output air coupler 170 is connected to the downstream side of the 3 rd flow path 113. The 2 nd output air coupler 180 constitutes a 2 nd outlet through which the 2 nd air flowing through the 4 th flow path 114 flows out. The 2 nd output air coupler 180 is provided on the side surface 110b of the housing 110 so as to be aligned with the 1 st output air coupler 170. The 2 nd output air coupler 180 is connected to the downstream side of the 4 th flow path 114.
As shown in fig. 6, 7, and 8, the housing 110 has a mounting portion 190. As shown in fig. 8, the solenoid valve unit 100 is attached to the unit frame F by fastening members (screws or the like) via the attachment portions 190 of the housing 110. In the example shown in fig. 8, the bracket B is interposed between the mounting portion 190 and the unit frame F, but the bracket B may be omitted.
The 1 st solenoid valve 120 and the 2 nd solenoid valve 130 are connected to a cable C. This allows the 1 st solenoid valve 120 and the 2 nd solenoid valve 130 to be energized. The energization of each of the 1 st solenoid valve 120 and the 2 nd solenoid valve 130 is controlled by the unit control portion 10. Air tubes are connected to the 1 st input air coupler 150, the 2 nd input air coupler 160, the 1 st output air coupler 170, and the 2 nd output air coupler 180, respectively.
In the solenoid valve unit 100 described above, when the package P is held by the package brake 51 via the winding bobbin holding portions 19a and 19b so that the package P can be rotated, the 1 st air is input from the 1 st input air coupler 150 to the solenoid valve unit 100, instead of the 2 nd air input from the 2 nd input air coupler 160. The unit control unit 10 does not supply current to the 1 st solenoid valve 120 and the 2 nd solenoid valve 130, and opens the 1 st solenoid valve 120 and closes the 2 nd solenoid valve 130. Thus, the 1 st air flows through the 1 st passage 111 through the 1 st electromagnetic valve 120, flows through the 3 rd passage 113 via the shuttle valve 140, and is supplied to the package brake 51 via the 1 st output air coupler 170. As a result, the package P can be rotatably held.
On the other hand, in the electromagnetic valve unit 100, when the package P is braked by the package brake 51 via the winding bobbin holding portions 19a and 19b, the 1 st air is input from the 1 st input air coupler 150, and the 2 nd air is input from the 2 nd input air coupler 160 to the electromagnetic valve unit 100. The unit control unit 10 energizes only the 2 nd solenoid valve 130, thereby turning the 1 st solenoid valve 120 on and also turning the 2 nd solenoid valve 130 on. Thereby, the 2 nd air flows through the 5 th flow path 115 and the 2 nd solenoid valve 130, and flows through the 2 nd flow path 112.
The 2 nd air flowing through the 2 nd flow path 112 passes through the 3 rd flow path 113 via the shuttle valve 140, and is then supplied to the package brake 51 via the 1 st output air coupler 170. The 1 st air is cut off from the flow by the shuttle valve 140. At the same time, a part of the 2 nd air flowing through the 2 nd flow path 112 flows through the 4 th flow path 114 and is supplied to the lift cylinder 57 via the 2 nd output air coupling 180. As a result, the package P is switched to the lifted state, and the package P is braked.
On the other hand, in a state where the package P is rotatably held by the package brake 51, when the unit control unit 10 energizes the 1 st electromagnetic valve 120, the 1 st electromagnetic valve 120 is closed, and the flow of the 1 st air is shut off by the 1 st electromagnetic valve 120. As a result, the supply of the 1 st air to the package brake 51 is stopped, and the holding of the package P is released.
As described above, the solenoid valve unit 100 includes: a housing 110 including 1 st to 3 rd flow paths 111 to 113 and a shuttle valve 140; a 1 st solenoid valve 120 integrated with the housing 110; and a 2 nd solenoid valve 130 integrated with the housing 110. The 1 st output air coupler 170 is provided in the housing 110. In the solenoid valve unit 100, an air circuit that can selectively switch and output either of the 1 st and 2 nd air can be realized by a structure in which the 1 st and 2 nd solenoid valves 120 and 130 and the housing 110 are integrated.
This can reduce space, air tubes and air joints, and reduce assembly man-hours, for example. Therefore, required resources can be reduced. Further, various components such as a base component existing in each of the 1 st and 2 nd solenoid valves 120 and 130 can be used in common, and thus the cost can be reduced.
In the solenoid valve unit 100, the 4 th flow path 114 is connected to the 2 nd flow path 112, and the 2 nd air flowing through the 4 th flow path 114 can be output from the 2 nd output air coupler 180. This makes it possible to provide a system for directly outputting the 2 nd air of high pressure.
In the solenoid valve unit 100, the 1 st output air coupler 170 and the 2 nd output air coupler 180 are provided on the same side surface 110b of the housing 110. This enables the 1 st air and the 2 nd air to be output in the same direction. The pipe switching can be easily performed when air is supplied to the external device (the package brake 51 and the lift cylinder 57) through the solenoid valve unit 100.
In the solenoid valve unit 100, the 1 st solenoid valve 120 is a normally open type solenoid valve that allows the 1 st air to flow therethrough when not energized. The 2 nd solenoid valve 130 is a normally closed solenoid valve that shuts off the flow of the 2 nd air when not energized. Thus, for example, in the case where the 1 st and 2 nd solenoid valves 120 and 130 are not energized during a power failure, the 1 st air lower in pressure than the 2 nd air can be output. The safety can be improved.
The solenoid valve unit 100 includes a 1 st input air coupler 150 and a 2 nd input air coupler 160. The 1 st input air coupler 150 is provided in the 1 st solenoid valve 120. The 2 nd input air coupler 160 is provided in the housing 110. The casing 110 also includes a 5 th flow path 115 inside which the 2 nd air flows from the 2 nd input air coupling 160 to the 2 nd solenoid valve 130. With such a configuration, the input of the 1 st air and the 2 nd air to the solenoid valve unit 100 can be specifically realized.
The automatic winder 1 includes winding bobbin holding portions 19a and 19b, a package brake 51, and a solenoid valve unit 100. When the package P is held by the package brake 51 so as to be able to rotate the package P, the 1 st electromagnetic valve 120 is opened and the 2 nd electromagnetic valve 130 is closed, and the 1 st air is supplied to the package brake 51 through the 1 st output air coupler 170. When the package P is braked by the package brake 51, the 2 nd electromagnetic valve 130 is turned on, and the 2 nd air is supplied to the package brake 51 through the 1 st output air coupler 170. In the automatic winder 1, the solenoid valve unit 100 can realize an air circuit for rotatably holding and braking the package P, and the required resources can be reduced in addition to realizing the air circuit.
In the solenoid valve unit 100, the 1 st solenoid valve 120 and the 2 nd solenoid valve 130 are disposed in close proximity to each other. In this configuration, the solenoid valve unit 100 can be configured compactly. In the automatic winder 1, the mounting portion 190 of the housing 110 is fixed to the unit frame F. In this configuration, the fixation of the solenoid valve unit 100 to the automatic winder 1 can be realized by the housing 110.
The 1 st solenoid valve 120 is a three-port solenoid valve, and has an inlet port to which the 1 st air is input and an outlet port from which the 1 st air is output. The other port of the 1 st solenoid valve 120 is sealed by a seal plug 124 (see fig. 6) provided in the housing 110. In the 1 st solenoid valve 120, the 1 st input air coupler 150 may be used in place of the seal plug 124. In this case, the 1 st solenoid valve 120 can be used as a normally closed type solenoid valve.
Similarly, the 2 nd solenoid valve 130 is a three-port solenoid valve having an inlet port for inputting the 2 nd air and an outlet port for outputting the 2 nd air. The other port of the 2 nd solenoid valve 130 is sealed by a seal plug 134 (see fig. 6) provided on the side surface of the 2 nd solenoid valve 130. In the 2 nd solenoid valve 130, the seal plug 134 and the 2 nd input air coupler 160 may be used in place of each other. In this case, the 2 nd solenoid valve 130 can be used as a normally open type solenoid valve.
While the embodiments of the present invention have been described above, the present invention is not necessarily limited to the above embodiments, and various modifications can be made without departing from the scope of the invention.
In the above embodiment, the 4 th channel 114 and the 2 nd output air coupler 180 for lifting the package P are provided in the casing 110, but the 4 th channel 114 and the 2 nd output air coupler 180 may be omitted in some cases.
In the above embodiment, the 1 st output air coupler 170 and the 2 nd output air coupler 180 are provided on the same side surface 110b of the housing 110, but the surface of the housing 110 on which the 1 st output air coupler 170 is provided may be different from the surface on which the 2 nd output air coupler 180 is provided.
In the above embodiment, the description has been given by taking the case where the winder unit 3 is provided with the tension detection device 24 as an example, but the yarn monitoring device 28 may be provided with a device for detecting the tension of the spun yarn Y.
In the above embodiment, the description has been given of the case where the winding drum 18 is provided with the traverse groove and the traverse of the spun yarn Y is performed by the traverse groove as an example, but the traverse of the spun yarn Y may be performed by an arm-type, belt-type, or rotary traverse mechanism. In this case, a roller without a traverse groove can be used as the auxiliary roller.
