The disk 51 is held at the open position when the rotary solenoid 52 is not operated (when not excited), and is rotated to the closed position when the rotary solenoid 52 is operated (when excited). In a state where the disk 51 is held at the open position, the air flowing through the blowing pipe 15 can freely flow toward the blowing nozzle 15a,
When the disk 51 is rotated to the closed position, the air flowing through the blowing pipe 15 is prevented from flowing toward the blowing nozzle 15a.

Each of the auxiliary nozzles 30 and 31 is formed to have a length that can be disposed at an operation position where the tip can reach the inside of the spinning machine table 1 and a standby position that does not interfere with the spinning machine table 1 when the traveling body 13 moves. Have been. Most of the auxiliary nozzles 30 and 31 are formed of flexible tubes 30a and 31a.
As shown in FIG. 5, an auxiliary nozzle 30 is
In the state where is located at the standby position, a fitting portion 32 serving as a cap at the tip of the nozzle portion 30b is provided. When the auxiliary nozzle 30 is not used, the nozzle portion 30b is fitted to the fitting portion 32, and the opening of the nozzle portion 30b is kept closed.

Each of the blowing pipe 14 and the suction pipe 15 is provided with a sensor 33 for detecting an obstacle. The sensor 33 provided on the blowing pipe 14 detects an obstacle present on the gear end GE side from the sensor 33, and
The sensor 33 provided in the sensor 5 is disposed so as to detect an obstacle present on the out-end OE side of the sensor 33. The control device 29 normally controls the switching device 28 so as to reciprocate between the gear end GE of the spinning machine stand 1 and the out-end OE along the traveling rail 11 to determine the traveling direction of the traveling body 13. Further, when the control device 29 receives an obstacle detection signal from the sensor 33, the control device 29 outputs a command signal for changing the traveling direction of the traveling body 13 to the switching device 28. The nozzle section 30 of the auxiliary nozzles 30 and 31 is provided in the blowing pipe 14 and the suction pipe 15.
Sensor 34 for detecting that b and 31b are at the standby position

8. The control device 29 and the sensor 34 constitute a stopping means.

Switching device 28, control device 29 and sensor 3
The electricity generated by the generator 27 is supplied to the battery 3 or 34 directly or after the storage battery is once charged.

Next, the operation of the above-configured apparatus will be described. The driving of the motor 6 of the pneumatic device 3 is started simultaneously with the start of the operation of the spinning machine stand 1, a negative pressure is generated in the cotton collecting box 5, and a suction action is generated in the suction nozzle 4a. As a result, the fleece sent from the roller part when the yarn breaks is sucked by the suction nozzle 4a. Further, the pneumatic device 3 has an action of sucking a part of the fiber which is not twisted into the yarn and the fly wool during normal spinning. The fleece or the like sucked by the suction nozzle 4a is temporarily stored in the cotton collecting chamber 5b. Each cotton collection room 5
The fleece and the like temporarily stored in b are collected by a centralized cotton collecting device.

At the same time as the operation of the spinning machine 1 is started, the movable cleaning device 12 starts reciprocating along the traveling rail 11 from one end of the spinning machine 1 to the other. The moving cleaning device 12 cleans the spinning machine stand 1 with an airflow blown out from the blowing pipe 15 while sucking and removing fluff, dust and the like on the floor surface from a suction port provided at a lower end of the suction pipe 14. Reciprocate.

When the section 19b of the drive belt 19 is arranged at a position where the section travels in a state of being pressed against the lower belt pulleys 20c, 21c and 22c, the transmission member 21 is in the section 1 section.
The belt pulley 21a is pressed against the section 9a, and the belt pulley 21c is pressed against the section 19b. In this state, the amount of rotation per unit time by which the drive belt 19 rotates the drive shaft 25 differs between the section 19a and the section 19b, and the speed difference causes the traveling body 13 to move in a predetermined direction (to the gear end GE in this embodiment). Move to. The section 19b of the drive belt 19 is an intermediate belt pulley 20b,
In a state where the traveling body 13 is disposed at a position where the vehicle travels in a state in which the traveling body 13 is pressed against the traveling bodies 13b and 22b, the speed difference is reversed and the traveling body 13 moves in the opposite direction. When the section 19b of the drive belt 19 is arranged at a position where the section travels in a state of being pressed against the upper belt pulleys 20a, 21a, 22a, the speed difference disappears and the traveling body 13 stops.

The spinning machine stand 1 is cleaned with the reciprocating movement of the movable cleaning device 12. The portion near the blowing nozzle 15a mounted on the blowing pipe 15 is effectively cleaned. However, the weighting arm 2 of the draft device 2
a, the chin pulley 8 for driving the spindle 7
a, it is difficult to remove fly waste accumulated on the tension pulley 8b and its support.

When cleaning an area where the cleaning effect is low depending on the air blown from the blowing nozzle 15a, the operator holds the auxiliary nozzle 30 for suction or the nozzle portion 30b of the auxiliary nozzle 31 for blowing, and holds the standby position. Move from. When the nozzle units 30b and 31b are moved from the standby position, the detection signal is not output from the sensor 34. Then, the control device 29 causes the switching device 28 to transmit the drive belt 19 to the belt pulleys 20a, 21a, 22a in the section 19b.
It outputs a command to move to a position pressed against. As a result, the section 19b of the drive belt 19 is
a, 21a, and 22a are brought into pressure contact with the traveling body 1
3 stops. At this time, the drive belt 19 continues to run, and the generator 27 and the blower 24 continue to rotate. Therefore, even when the traveling body 13 is stopped, a negative pressure is applied to the suction pipe 14, and pressurized air is supplied to the blowing pipe 15.

When the traveling body 13 stops, an excitation command is output from the control device 29 to the rotary solenoid 52, and the rotary solenoid 52 is excited. Then, the switching damper 50 prevents the blowing of the air from the blowing nozzle 15a, and is kept in a state in which the blowing of the air is possible only from the auxiliary nozzle 31.

Then, the operator can use one of the auxiliary nozzles 30,
The 31 nozzle portions 30b, 31b are guided to the vicinity of a desired location. If the auxiliary nozzle 30 for suction is used, the accumulated fly waste is removed by suction, and if the auxiliary nozzle 31 for blowing is used, the accumulated fly waste is blown off. When the operator can easily see the position of a desired cleaning portion such as the draft device 2 or the weighting arm 2a, the auxiliary nozzle 30 for suction is used. Further, when it is difficult for the operator to visually recognize the position of the cleaning portion, such as the support bearing of the chin pulley shaft 8 and the tension pulley 8b, it is preferable to use the auxiliary nozzle 31 for blowing.

After the cleaning operation by the auxiliary nozzles 30 and 31 is completed, when the nozzle portions 30b and 31b are returned to the standby position, the detection signal of the nozzle portions 30b and 31b is output from the sensor. The control device 29 transmits the drive belt 19 to the switching device 28 in the section 19b of the belt pulleys 20b and 21.
b, 22b is output. As a result, the traveling body 13 starts traveling. Running body 1
When the vehicle 3 starts running, a demagnetization command is output from the control device 29 to the rotary solenoid 52, and the rotary solenoid 52 is demagnetized. Then, the switching damper 50 returns to a state where air can be blown out from the blowing nozzle 15a.

This embodiment has the following effects. (1) Auxiliary nozzles 30 and 31 are provided which can be disposed at an operation position where the tip can reach the inside of the spinning machine table 1 and at a standby position where the running body 13 does not interfere with the spinning machine table 1 when moving. Therefore, it is possible to clean the portion where it is difficult to remove fly waste by the air blown out from the blowing nozzle 15a of the moving cleaning device 12 using the suction source and the blowing source provided in the moving cleaning device 12. it can.

(2) Since the auxiliary nozzles 30 and 31 are provided in a state of being branched from the suction pipe 14 or the blowing pipe 15, the mounting is simpler than when the auxiliary nozzles 30 and 31 are provided directly on the traveling body 13.

(3) Most of the auxiliary nozzles 30, 31 are formed by the flexible tubes 30a, 31a, so that it is easy to guide the tips of the auxiliary nozzles 30, 31 to desired positions.

(4) Since the traveling of the traveling body 13 is stopped when the auxiliary nozzles 30 and 31 are actuated, the operation of guiding the tips of the auxiliary nozzles 30 and 31 to a desired location is continued. It's easier than if you were.

(5) Since both the auxiliary nozzle 30 for suction and the auxiliary nozzle 31 for blowing are provided,
The cleaning operation can be performed by selecting an auxiliary nozzle having a better cleaning effect.

(6) When the auxiliary nozzle 30 for suction is fitted to the fitting portion 32 when not in use and the opening of the nozzle portion 30b is kept closed, suction is performed when the auxiliary nozzle 30 is not used. A reduction in the suction effect of the pipe 14 is prevented.

(7) The movable cleaning device 12 is mounted on each spinning machine base 1
Since it is equipped for each, a plurality of mobile cleaning devices 1
2, the cleaning operation can be performed more efficiently. (8) Since the blowing of the air from the blowing nozzle 15a is interrupted while the running is stopped, it is possible to avoid adversely affecting the spinning while performing the cleaning operation using the auxiliary nozzles 30 and 31. .

(Second Embodiment) Next, a second embodiment will be described with reference to FIGS. In this embodiment, instead of the worker performing the cleaning work using the auxiliary nozzle,
The point that it is automatically performed and the point that only the auxiliary nozzle 31 for blowing is provided are greatly different from the above-described embodiment. The same parts as those of the above-described embodiment are denoted by the same reference numerals, and the detailed description is omitted.

An auxiliary nozzle 31 for blowing is connected to the middle of the blowing pipe 15 at a position higher than the height at which the weighting arm 2a is provided. The auxiliary nozzle 31 is rotatably connected to a connecting cylinder 35 protruding from a side surface of the blowing pipe 15 and is capable of rotating the motor 3 forward and backward.
6 and is connected to a connecting member 37 rotated by a motor 36. As shown in FIG. 7A, the connecting member 37 is formed with a connecting portion 37a extending at right angles to the rotation axis thereof, and the base end of the auxiliary nozzle 31 formed of a flexible tube is fitted to the connecting portion 37a. Have been combined.

As shown in FIGS. 6A and 6B, a support plate 3 is provided between the suction pipe 14 and the blowing pipe 15.
8 are fixed horizontally via clamp portions 38a formed at both ends. The motor 36 is supported on the support plate 38, and its output shaft 36 a is connected to the connecting member 37. An auxiliary nozzle 31 is mounted inside a chain type guide belt 39 (only the outer shape is shown), one end of which is fixed to the connecting member 37. The guide belt 39 is configured to be bent only inward, and when the connecting member 37 is rotated in the winding direction, the guide belt 39 is wound on the connecting member 37 from the base end side,
When rotated to the feeding side, it is fed in a tangential direction from the tip side. The motor 36 and the guide belt 39 constitute moving means for moving the tip (nozzle part 31b) of the auxiliary nozzle 31 between the operating position and the standby position.

A guide belt 39 is provided on the support plate 38.
A pair of guide rollers 40 for regulating the feeding direction of the roller are supported via a bracket 41. Guide roller 4
Numeral 0 is arranged at a position for guiding the auxiliary nozzle 31 so as to be extended slightly downward. When the auxiliary nozzle 31 is completely wound, the nozzle portion 31
The b is held by the guide roller 40 on the side of the spinning machine 1 without interfering with the spinning machine 1 when the traveling body 13 travels.

The nozzle portion 31b is provided with a hole 42 for blowing air to both the left and right sides. The traveling body 13 stops the auxiliary nozzle 31 intermittently at a position corresponding to the center of the adjacent weighting arm 2 to assist the auxiliary body 31. The cleaning operation by the nozzle 31 is performed. The control device 29 controls the switching device 28 based on the count value of a counter constituting a rotation amount detection device that detects the rotation amount of the drive wheel 26, and controls the traveling of the traveling body 13 every time the count value reaches a predetermined value. Stop. Then, the control device 29 outputs a forward rotation command to the motor 36,
Is rotated forward by a predetermined amount to dispose the auxiliary nozzle 31 at the operation position, and after a predetermined time elapses, the motor 36 is rotated reversely by a predetermined amount to return the auxiliary nozzle 31 to the standby position.

In this embodiment, the movable cleaning device 12 moves intermittently, and the auxiliary nozzle 31
Is moved from the standby position to the operation position, and the base end of the weighting arm 2a is cleaned. Nozzle part 31
Since air is blown from both sides of the draft nozzle b, a part of the roller part of the draft device 2 is also cleaned before the auxiliary nozzle 31 moves from the standby position to the operation position.

Therefore, this embodiment has the following effects in addition to the same effects as (1), (2), (4), (7) and (8) of the above embodiment. (9) Since the auxiliary nozzle 31 is automatically arranged at the operation position and the standby position, it is not necessary for the operator to operate the auxiliary nozzle 31 one by one.

(10) Since the auxiliary nozzle 31 is arranged at the standby position in the winding state and moves linearly to the operation position, the moving means for moving the nozzle portion 31b between the operation position and the standby position becomes compact. .

(11) Since the auxiliary nozzle 31 for blowing is automatically arranged at the operation position, the cleaning effect can be improved even if the accuracy of disposition at the operation position is lower than in the case of the auxiliary nozzle 30 for suction. I get enough.

The embodiment is not limited to the above, and may be modified as follows, for example. In the second embodiment, an auxiliary nozzle 31 for cleaning the chin pulley 8a and the tension pulley 8b may be provided. The auxiliary nozzle 31 is provided so as to advance obliquely upward from below the spindle rail. When the auxiliary nozzle 31 moved to the operation position from below the spindle rail and moves in the longitudinal direction of the spinning machine table 1 in that state, it interferes with the spring piece. Therefore,
It is not necessary to reciprocate between the standby position and the operation position for each stop position for cleaning the weighting arm 2a, and to move to the standby position before passing through the portion corresponding to the spring piece, otherwise. It may be held in the working position.

As a moving means for moving the nozzle portion 31b of the auxiliary nozzle 31 between the standby position and the operation position, instead of the combination of the guide belt 39 and the motor 36, a guide belt 39 and a double-acting telescopic air cylinder are used. May be used. The air cylinder and the control valve (not shown) are provided on a support plate 38 supported between the suction pipe 14 and the blow pipe 15 as in the second embodiment.
