BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning system for a spinning machine group that cleans cotton wool on a spinning machine stand with a blow cleaner that runs along a spinning machine such as a roving machine, a spinning machine, and a twisting machine.

[0002]

2. Description of the Related Art Conventionally, as a cleaning system for a spinning machine group, a blow cleaner for cleaning the spinning machine by blowing and sucking air is provided in each spinning machine so as to run along the spinning machine, and the cleaning is performed by the blow cleaner. When a movable work machine comes into contact with an arbitrary one of the spinning machines in the starting state during work due to a splice or the like, the blow cleaner of this machine is used so that the work machine and the blow cleaner do not interfere with each other. There was one in which one end was put on standby and the work machine moved along the spinning machine to perform work. However, in this cleaning system, as described above, in the spinning machine in which the blow cleaner is on standby, the cotton wool is not cleaned during the work of the working machine (for example, about 80 minutes in the case of Shinotsugi of a long spinning machine with 960 spindles).
A large amount of cotton wool accumulates. Therefore, when the blow cleaner starts to run again after the work of the working machine is finished, the accumulated fly cotton is blown off and the yarn being spun into the yarn is broken.

Therefore, various devices have been proposed in order to solve the above problems, but Japanese Patent Publication No. 43-2498.
In Japanese Patent Laid-Open No. 7-74, a movable part that is expandable and contractible is provided in the middle part of the blow pipe, and the lower part of the blow pipe is connected to the wire of the hoisting machine to hinder the traveling of the working machine or the like while the blow cleaner is traveling. In such a case, there is proposed a device in which the lower end of the blow pipe is moved upward by the hoisting machine to a position above the working machine and, after passing through the working machine, is lowered again to the original position to continue the work.

Further, in Japanese Patent Laid-Open No. 63-120121, there is a blow cleaner that can be run even by a spinning machine in which the working machine is working. This blow cleaner is located above and behind the working machine of the wind guide pipe hanging on the side surface of the spinning machine. A rotating part is provided, and the upper and lower pipes divided by this rotating part are connected by a coil spring, and when the working machine reaches the position where the work machine is working while the blow cleaner is traveling, the pipe below the rotating part will work. Engage the machine,
When the blow cleaner further moves in that state, it is rotated about the rotating part in the direction away from the spinning machine, passes the rear side of the working machine, and when the engagement with the working machine is released, the pipe is coiled by the coil spring. Has been proposed in which the machine is returned to its operating position with respect to the spinning machine stand and then the normal cleaning operation is continued.

[0005]

In order to avoid interference with the working machine, the blow pipe is retracted upward so that the blower pipe escapes. It is virtually impossible to shrink the blowpipe to pass it.

Further, in the case where the spinning machine under operation is cleaned by a blow cleaner traveling above the spinning machine, a pipe below the rotating portion provided in the blower pipe of the blow cleaner and a pipe connecting pipe, etc. This pipe was moved to the rear side of the work machine due to the collision with the work machine to perform work, and the blow cleaner passed through the work machine. This is not preferable because it may give unnecessary shocks to the working machine for performing the work, and may cause mistakes in pipe joints and pipe replacement. Furthermore, there were cases where the pipe itself was damaged by a collision.

In view of the above, an object of the present invention is to provide a practical cleaning system for a spinning machine to which the working machine is attached, in which the working machine can perform normal work and which can clean the spinning machine. It is to be.

Blow pipe 10 having a crank shape is connected to left and right objects. Further, the suction unit 7 is also hung down along the side portion of the spinning machine 1, and a suction pipe 12 having a suction nozzle 11 at the lower end thereof is connected symmetrically to the left and right.

Next, referring to FIG. 3, the blowing direction switching device 1
5 will be described. A connecting pipe 16 is fixed to the lower surface of the shoulder portion 8 of the blow unit 6, and the connecting pipe 1
An upper end of the crank-shaped blow pipe 10 is rotatably supported by a lower end of 6 through a bearing 17. A driven gear 18 is welded to the upper portion of the blow pipe 10 and meshes with a drive gear 20 of a motor 19 fixed to the lower surface of the shoulder portion 8. The motor 19 is connected to the power supply line and the signal line through the four shoes 21 shown in FIG. 1, and the other end of the signal line is provided at one end (for example, the GE side) of each spinning machine 1 shown in FIG. It is connected to a control device 25 that performs control according to the flowchart of FIG. Therefore, in a normal cleaning state, the blow nozzle 3 of the blow cleaner 3 is directed to the side surface of the spinning machine 1 on which the blow cleaner 3 runs, as shown by the solid line in FIG. When there is a work machine contact signal, the control device 25 outputs the blowing direction switching signal output at a predetermined timing (for example, once every two traverses of the blow cleaner 3) to drive the motor 19 to rotate the blow pipe 10. Direction R (shown in Figure 4)
When rotated by 180 degrees, as shown by an imaginary line in FIG. 1, it is oriented toward the side surface of the spinning machine 1 adjacent to the spinning machine 1. In FIG. 4, 26 is the end of the spinning machine 1 (GE side).
Is placed and transported on a transporter 28 that travels on the rails 27,
This is a working machine for performing work such as piecing along the front surface of the spinning machine 1, and this carrier 28 is attached to the spinning machine 1 to be worked and its bridge rail (not shown) is guided to the working machine of the spinning machine 1. When connected to a rail, limit switches 30 provided at one end (GE side) of each spinning machine are turned on, and a stand-by signal is output. Further, as shown in FIG. 1, in the present embodiment, the distance from the tip of the nozzle to the tip of the blow nozzle becomes smaller than the width of the working machine depending on whether the blow nozzle of the blow nozzle is directed to the corresponding spinning machine or the adjacent spinning machine. There is.

Next, the operation of the cleaning system 2 for the spinning machine group 1 configured as described above will be described with reference to FIGS. In a normal case, the blow cleaner 3 reciprocates on the rail 5 along the longitudinal direction of the spinning machine 1 and moves to the blow pipe 10.
As shown by the broken line and the imaginary line in FIG. 4, air is blown from the blowing nozzle 9 facing the center side of the spinning machine 1 to blow off the cotton wool of the spinning machine 1 to drop it on the floor surface, and it is deposited on the floor surface. Suction nozzle 1 of suction pipe 12
It is sucked and removed by 1 (step S1).

Next, the operation of the arbitrary spinning machine 1 when it is in a state where work such as piecing is to be performed will be described.
First, the carrier 28 having the working machine 26 mounted thereon is brought into contact with the spinning machine 1, and a contact signal is output from the limit switch 30. By confirming this contact signal in step S2, the controller 25 of the contact spinning machine makes the blow cleaner 3 which has been running until now stand by at the other end (the OE side) of the spinning machine 1, and this spinning machine 1 operates. A work start signal indicating that the spinning is started and the machine number of this spinning machine are output to the control devices 25 of the spinning machines 1 adjacent to each other (steps S3 and S4). In step S6, the adjacent control device 25 compares the sent machine number with its own machine number to determine which of the left and right sides the work start signal has been input, and further in step S7, blows. The blower direction switching signal is output to the blower direction switching device 15 on the signal input side of the cleaner 3 once every two traverses, the blower direction switching device 15 of the blow cleaner is operated, and the blow pipe 10 of the blow cleaner 3 is moved to 180 degrees. It is rotated and the blow-out nozzle 9 is directed toward the side surface of the splicing machine 1 as shown by the solid line in FIG. Therefore, the blow nozzle 3 adjacent to the contact table spinning machine 1 is cleaned while cleaning the corresponding spinning machine 1.
After traversing once, the operation of traversing once while cleaning the contact spinning machine 1 is repeated. After that, when the work machine 26 finishes the work and is placed on the transport machine 28 again, the limit switch 10 is turned off, the stand-off is determined in step S5, and the control device 25 of the spinning machine 1 in which the work is being performed is performed. Is
In step S9, a work end signal is output to the control devices 25 of the spinning machines 1 on both sides of the spinning machine 1, and the control devices 2 on both sides of the spinning machine 1 are output.
5 determines the input of this work end signal up to step S8, stops outputting the blowout direction switching signal to the blow cleaner 3, and the blow cleaner 3 performs the above-mentioned normal cleaning.

As described above, in the cleaning system 2 for the spinning machine group 1 of the present invention, the blow cleaner 3 of the spinning machine in which the work is performed is made to stand by, and the cleaning of the spinning machine 1 during this work is performed by this spinning machine 1. Blow cleaner 3 of spinning machine 1 next to
Since it is performed in step 1, it is possible to prevent a large amount of fly waste from accumulating in the cleaning area of the spinning machine 1 during work.

In the cleaning system of this embodiment, when the blow nozzle of the blow cleaner is directed to the side surface of the adjacent spinning machine, the tip of the blow nozzle is located in the moving space of the working machine. Therefore, the interval between the spinning machines can be set so that the blow pipe adjacent to the rear surface of the working machine is passed, and the installation space of the spinning machine in the factory layout can be reduced.

The blow-out direction switching device of this embodiment is provided at the upper end of a crank-shaped blow pipe, and the entire crank-shaped blow pipe rotates to switch the blow-out direction. The device may be provided below the crank portion of the blow pipe so that only the blow pipe below the crank portion rotates.

Further, instead of the blow cleaner 3 of this embodiment, two blow pipes are hung down on a shoulder portion 8 of a blow unit 6 via a switching valve, and the blow nozzle of one of the blow pipes corresponds to that of a spinning machine. The blow cleaner is configured so that the blow nozzle of the other blow pipe is directed to the side of the adjacent spinning machine. The controller may control the switching valve of the blow cleaner of the spinning machine to be switched at a predetermined timing.

Further, the control device 25 of this embodiment is provided for each spinning, but one central processing unit waits for the blow cleaner 3 of the splicing machine by the splicing signal from the limit switch 30. Then, control such as sending a blowing direction inversion signal to the blow cleaner 3 adjacent thereto may be performed.

[0019]

As described above, in the cleaning system for a spinning machine according to the present invention, the blow cleaner is configured to be switchable between the side of the spinning machine corresponding to the air blowing direction and the side of the spinning machine adjacent to the blower side. When the machine is brought into contact with the machine, the control device switches the blowing direction of the blow nozzle next to the machine to be operated at a predetermined timing, so that the working machine can perform the work normally. The spinning machine can be cleaned by the adjacent blow cleaner, and it is possible to prevent a large amount of fly dust from accumulating on the spinning machine. Further, since the blow pipe is not contracted upward by the hoisting machine to avoid interference with the working machine as in the conventional case, cleaning can be performed even on a spinning machine in which a tall working machine is working.
