Description

Description: TECHNICAL FIELD The present invention relates to a wagon type working machine (mounted on a carrier) along each machine end of a spinning machine group including a plurality of spinning machines of the same type, such as a spinning machine or a roving machine. A machine that moves along the machine edge or a self-propelled type) is arranged so that the wagon type work machine performs doffing and the like on the machine according to the work request from the machine. The present invention relates to a traveling control device for a wagon type working machine of the working system for a spinning machine group.

2. Description of the Related Art Explaining a conventional work system, for example, a doffing system in a spinning machine group, the operation of the spinning machine and the movement of the wagon-type working machine (doffing machine) are completely independent, and the wagon-type working machine is The moving direction is changed only at both ends of the spinning machine group, and once the moving direction is determined at one end of the group, the doffing of the spinning machine is stopped during the movement until reaching the other end of the group. Even if they went, they continued to move in the same movement direction and changed their direction only when they reached the other end of the group.

Problems to be Solved by the Invention According to the above-mentioned conventional technique, for example, as shown in FIG. 7, during the movement from one end of the spinning machine group to the direction A, the automatic counter of the spinning machine is set in advance. A spinning machine (for example, SF5) that has been wound up to the pipe forecast winding amount lights a call-in lamp to the doffing machine, and the lighting of this call-in lamp is detected by the carrier AC of the running doffing machine and the spinning It stops at the spinning machine SF5 end and comes in contact with it, then stops the spinning machine and doffs. Considering the case where a spinning machine (for example, SF4) on the upstream side of the doffing machine's moving direction (direction of arrow A in this example) lights up the call-in lamp by the end of the doffing of this spinning machine, this spinning machine SF4 For doffing, the doffing machine AD moves to the spinning machine SFn at the end of the spinning machine group in the A direction, changes the direction to the direction of arrow B, and then moves to the front of the spinning machine SF4 for the first time. Since the lighting is detected and the doffing is performed by contacting the stand, the moving distance (moving time) of the doffing machine AD becomes longer than necessary, which affects the life of the traveling system of the doffing machine AD. Spinning machine SF4 There was a problem that the fried egg was delayed. In addition, in recent years, there is a tendency to spun out different numbers of spinning yarns in the same spinning machine group to support high-mix low-volume production.For example, spinning spinning thick yarns to increase the operating rate of spinning machines. However, if the spinning machine is tried to doffing with priority, the conventional spinning machine that changes the direction at the group end has a problem that it is not practical because the timing of switching the moving direction is restricted. Further, in recent years, doffing by a wagon-type doffing machine is being put to practical use also in a roving machine, and there is a problem similar to that of the doffing in the spinning machine group described above. Development was desired. Further, as a wagon-type working machine, Shino exchange machine shown in Japanese Patent Laid-Open No. 58-120826 is known, and even in such a working machine, movement by the traveling control as described above is similar to that of the doffing machine. There was a problem that could not be done efficiently.

Means for Solving the Problems In order to solve the above problems, the present invention provides a work system of a spinning machine group using a wagon type working machine capable of switching a moving direction, wherein a spinning machine or a wagon type working machine is a wagon type working machine. A means for outputting the spinning machine base number corresponding to the current position of the spinning machine is provided, and the spinning machine receives a work request signal for requesting the wagon type working machine based on the spinning amount of each spinning machine before outputting the work start signal. The main controller to which the current position signal and the work request signal of these wagon type working machines are provided is provided with a forecast table for registering the machine number of the spinning machine that issued the work request signal, and the forecast table. Corresponding to the present position of the wagon type working machine, including a means for checking the registration order in the table, a selection means for determining the machine number of the spinning machine to be worked next based on the registration data in the forecast table. The machine comprises a machine number and a machine number of the spinning machine to be worked next selected by the selecting means, and means for determining the moving direction of the wagon type working machine, and a transmitter for transmitting the determined moving direction. The wagon-type working machine includes a receiver that receives a command signal from the transmitter. When the receiver receives the command signal, the wagon-type working machine is moved from the current position of the wagon-type working machine to the next position. It is characterized in that a control device for directly moving the spinning machine to be worked is provided.

Operation According to the above configuration, the current position of the wagon type work machine is monitored as the machine stand number of the spinning machine, and the signal from the output means of the work request signal of each spinning machine is registered in the forecast table of the main control unit. In the control device, at a predetermined timing (for example, when the work on a certain spinning machine is finished and the bridge rail is released), the machine number of the spinning machine to be worked next is selected by the selecting means based on the registered data in the forecast table. Then, determine the moving direction of the wagon type working machine from this machine number and the machine number of the spinning machine that indicates the current position of the wagon type working machine, send this moving direction with a transmitter, and issue this moving direction command. The receiver of the wagon type working machine receives and moves the wagon type working machine from the current position toward the spinning machine to be worked next by this movement direction command.

Example An example in which the present application is applied to a work system of a spinning machine group will be described below. As shown in FIG. 7, the spinning machines SF1 to SFn are arranged in parallel in the factory to form a spinning machine group G. Less than,
Since all the spinning machines SF1 to SFn have the same structure, they are referred to as a spinning machine SF. A pair of rails 1 along the machine end of the spinning machine group G,
1 is laid. On the rails 1 and 1, traveling wheels 2 of a carrier AC of a wagon-type doffing machine AD (hereinafter, doffing machine AD),
2 is placed and driven by the drive motor M to carry the carrier.
AC is designed to travel on rails 1 and 1.
The carrier AC is provided with a suspension rail 5 on which the driving wheels 3 and driven wheels 4 of the doffing machine AD are mounted, and a bridge rail 7 connected to a guide rail 6 arranged along the front surface of the spinning machine SF at one end thereof. Bring down the bridge rail 7 and connect the rails in a straight line, start the doffing machine AD from both sides of the carrier AC into the guide rail 6, and mount the doffing machine AD on both sides of the carrier AC from the guide rail 6 and remove the bridge rail 7 to move. I am doing it. A control box 8 incorporating a carrier-side control device such as a receiver, which will be described later, is provided above the carrier AC. From the control box 8, four trolley wires 10 to 13 suspended from a ceiling 9 are provided. The shoe 14 that makes sliding contact is the arm

Further, in this control box 8, light receivers 16 and 17 are provided on the side of the spinning machine SF, and a doffing machine call-in lamp provided in the spinning machine SF.
La1 and full lamp La2 can be opposed to each other. The spinning machine SF has a limit switch LS at the end of the guide rail 6.
When the bridge rail 7 is connected to the spinning frame SF, the spinning frame SF is regarded as a full pipe and the full pipe lamp La2
Is turned on, and the signal is used as a position signal indicating which machine of the spinning machine group G is fried by the carrier AC as described later. Further, the spinning machine SF is provided with a known auto-counter 18 connected to a front roller (not shown) as a means for outputting a doffing signal (work request signal) and monitoring the spinning amount of the spinning yarn. Is set to the amount of spinning that can be doffed (for example, 90% of the full pipe spinning amount) and the spinning amount of full pipe, and when each spinning amount reaches the full pipe forecast signal (work request signal) A pipe signal (work start signal) is output. The signals from the auto counter 18 and the signals from the limit switch LS are once taken in by the sequence control device 19 (programmable controller; microcomputer application device capable of performing various sequence operations by program) in the spinning frame SF. It has become. The sequence control device (first controller) 19 is connected to another sequence control device (hereinafter, second controller) 21 in the separately arranged main control device 20, and exchanges data and commands. Main controller 20
Is composed of a keyboard (setting device) 22, a second controller 21, and a transmitter 23 of the transmission unit, and a program according to the flowcharts shown in FIGS. 4 and 5 is written in the second controller 21. This second controller 21
The signals of the auto counter 18 from the first controller 19, the signals from the limit switch LS, and the signal from the keyboard 22 are input to the input side of the, and from the output side,
A selection signal Se1 for setting which spinning machine SF data is to be taken in or data to be sent, and a doffing machine call-in signal Ca11 and a transmitter 23 when a doffing machine base is determined as described later.
To the right and left command signals are output. On the spinning machine side, when the doffing machine call-in signal Ca11 is received, the first controller 19 turns on the doffing machine calling lamp La1. The transmitter 23 of the transmission unit receives the leftward command L and the rightward command R from the second controller 21 in the carrier AC using two of the AC power supply trolley wires 10 to 12 and the signal line 13. It is to be transmitted to the device 24, by creating an AC waveform with different phases from the AC power supply waveform in the phase conversion circuit, and combining this AC waveform to form a pulse train consisting of a large number of pulses with different polarities and phases. Any one of them is associated with a leftward command L and a rightward command R in a one-to-one correspondence, and a pulse corresponding to the leftward or rightward signal ON is placed on the signal line.

Next, the carrier side control device in the control box 8 will be described. The carrier side control device is the receiver of the transmission unit.
24 and third sequence control device (third controller) 25
And general-purpose inverter device 26 and brake power supply unit
It is composed of 27 and. The receiver 24 checks the phase and polarity of the pulse from the transmitter 23, and outputs right and left row commands R and L corresponding to the input signal. The output of the third controller 25 is a relay RU for traveling.
N, RUN-R, and a brake relay RB1 are connected, and the right side and left side command signals R from the receiver 24 are connected to the input side.
A confirmation signal of the doffing machine call-in lamp La1 from L and the light receiver 16 is inputted. Further, a drive motor M and normally running contacts RUN1 and RUN-R1 of the traveling relays RUN and RUN-R are connected to the inverter device 26. The brake power supply unit 27 is connected to the brake MB and the contact RB1-1 of the brake relay RB1, and the right run command signal R causes the relay RUN,
RUN-R turns ON, drive motor M rotates forward, and carrier AC
To the right, and the left command signal L turns on only the relay RUN, causing the carrier AC to move to the left.

Next, the operation will be described with reference to FIGS. 4 and 1. The spinning machines SF in the spinning machines group G are adapted to spin out spinning yarns of various counts, and the spinning numbers are preliminarily stored in the second controller 21 in correspondence with the machine number of each spinning machine SF. The case of being stored will be described. Spinning machine group G starts operation, and doffing machine AD
Is performing the doffing of any spinning machine, the spinning data from another spinning machine is fetched in step 1 of the flowchart. If some of them output the full pipe forecast signal from the automatic counter 18, in step 2 and 3, the machine number is registered in the full pipe forecast table in the second controller 21 shown in FIG. In step 4, it is determined whether the doffing is in progress, and by the time the doffing is completed, the data from other machines are read one after another and added to the full pipe forecast table. When the end of the doffing is confirmed by turning off the limit switch LS, the spinning machine to be fried next is selected in step 5, and its position is given by the machine stand number. In the present embodiment, this is determined according to the order and number registered in the full pipe forecast table according to the flowchart shown in FIG. According to this, it is judged in step 6 whether or not there is a signal that a full pipe is issued among those registered in the full pipe forecast table, and when there is no full pipe signal, the thickest number in the full pipe forecast table is determined in step 7. Select the item, judge whether there is the same number in step 8, and if there is the same number, check the order of registration in the full pipe forecast table in step 9, and select the item registered first in step 10 next. It is decided as the machine base to be fried.
Next, at step 11, the doffing end table and the machine to be next doffed are compared in position from the machine No. Here, the doffing end table has already been stored in the second controller 21 in step 18 because the bridge rail 7 turned on the limit switch LS at the time of doffing. Then, in step 12, the moving direction is determined, and in step 13, the doffing machine call-in signal Ca11 is output to the first controller 19 together with the selection signal Se1, and the spinning machine selected in response to this.
The first controller 19 of SF turns on the doffing machine call-in lamp La1. Next, by determining the moving direction in step 12, the command signal from either the left row or the right row is transmitted by the transmitter 23
Output to. The transmitter 23 receives this signal from the carrier AC receiver.
When the rightward command signal R is input to the controller 24, the third controller 25 turns on the relays RUN and RUN-R to close the relay contacts RUN1 and RUN-R1 and moves the carrier AC to the right.
Further, when the leftward signal L is input, only the relay RUN is turned on, the contact RUN1 is closed, and the carrier AC is leftwardly moved. When the receiver 16 confirms the doffing machine call-in lamp La1 lit in step 13 in this way, the relays RUN and RUN-R are turned OFF in the right row, and the relay RUN is turned OFF in the left row. Instead, the relay RB1 is turned on, the contact RB1-1 is turned on, the brake MB is operated, and the drive motor M is braked and stopped. When stopped, the carrier rail bridge rail 7
Is tilted down and connected to the guide rail 6, the limit switch LS is turned ON, and it is determined that the next machine has been reached in step 17, and this machine number that was joined is stored as the current doffing board in step 18. Then, in step 19, the doffing machine base number is deleted from the full pipe forecast table and updated. Of course, when the machine stand is full, even if it is not full, the limit lamp LS is turned on to turn on the full tube lamp La2, and the receiver 17 confirms this lighting. The doffing machines AD on both sides of the carrier AC are started to doffing. Thus, steps 1 to 19 are repeated. Therefore, when the doffing with the spinning machine SF5 in Fig. 7 is completed,
Whether the machine to be next doffed is the spinning machine SF4 or SF7, the machine can be moved freely from the machine after the doffing in either direction, and in the present embodiment, within the same time (for example, 1 Day)
In the above, it is possible to preferentially doff the thick spinning yarn having a larger number of doffing as compared with the fine counting, thereby improving the operation efficiency of the entire spinning machine group.

In the present embodiment, a spinning machine group with a mixed number is explained, and in determining the spinning machine to be doffed next, the full pipe forecast table and the count were determined as a reference. Among the registered spinning machines, the remaining time to the full pipe and the count are used as a reference, or in addition to these factors, the doffing order among the spinning machines registered in the full pipe forecast table is set. Assuming that the moving time from the current position of the carrier and the doffing time are taken into consideration, next doffing shall be performed so that each spinning machine does not stop, or even if it stops, the time is minimized. The machine to be played may be selected.
When all the numbers are the same, the doffing machine bases may be determined only in the order of registration in the full pipe forecast table. Further, in the present embodiment, the spinning amount of the spinning machine is monitored by using the automatic counter, and the full pipe forecast signal is output to the sequence controller (first controller). However, for example, a predetermined spinning machine is used instead of the automatic counter. A pulser that generates a predetermined pulse for each output length is connected to the front roller, and the pulse is input to a microcomputer including a CPU, ROM, and RAM in place of the first controller, counted in this microcomputer, and preset. A full pipe forecast signal may be output to the second controller when the full pipe forecast count value is reached. Further, in the present embodiment, only the moving direction command is output to the doffing machine, and the doffing machine call-in signal is output separately from this, but instead of this, the doffing machine is given the moving direction and the traveling distance. In this way, it may be moved to the spinning machine to be fried next. In addition to the present embodiment, the position signal of the doffing machine may be, for example, attached to each spinning machine with a machine number bar code, and the doffing machine may be equipped with a bar code reader for output. In addition, even in the Shino exchange machine known as such a wagon type working machine,
Needless to say, the transfer efficiency is improved by applying the present invention.

As described above, in the present invention, a rail is laid along the machine base end of a spinning machine group in which a plurality of spinning machines are juxtaposed, and on this rail,
In a work system for a group of spinning machines, in which a wagon-type working machine whose movement direction can be switched is moved to perform a doffing operation for a spinning machine that requires a work, a wagon-type working machine is used for the spinning machine or the wagon-type working machine. A means for outputting the spinning machine base number corresponding to the current position of the spinning machine is provided, and the spinning machine receives a work request signal for requesting the wagon type working machine based on the spinning amount of each spinning machine before outputting the work start signal. The main controller to which the current position signal and the work request signal of these wagon type working machines are provided is provided with a forecast table for registering the machine number of the spinning machine that issued the work request signal, and the forecast table. Corresponding to the present position of the wagon type working machine, including a means for checking the registration order in the table, a selection means for determining the machine number of the spinning machine to be worked next based on the registration data in the forecast table. A unit number and means for determining the moving direction of the wagon type working machine from the machine number of the spinning machine to be worked next selected by the selecting means, and a transmitter for transmitting the determined moving direction, Further, the wagon type work machine includes a receiver for receiving a command signal from the transmitter, and when the receiver receives the command signal, the wagon type work machine is operated next from the current position of the wagon type work machine. Since a control device was provided to move directly to the spinning machine to be moved, for example, it moves along the machine base end of the spinning machine group, and the conversion of the moving direction is limited to the group end part. In comparison, in the present invention, the moving direction of the wagon type working machine can be freely changed from the current position of the working machine to the spinning machine to be worked next, and the waste of moving the wagon type working machine can be reduced. Change the moving direction of the work machine Not restricted to timing, work by efficient and practical working machine are possible without troubling human intervention. Also, its movement control is
Since it is performed based on the work request signal output prior to the work start signal, there is time to actually start the work.For example, during doffing work, the wagon type work machine arrives at the spinning machine to work. By that time, the frequency of stopping the spinning machine can be reduced, which can contribute to improving the operating rate of the spinning machine.
