Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to movement control of an automatic machine that moves along the machine base of a large number of spinning machines constituting a spinning machine group.

2. Description of the Related Art Conventionally, an automatic machine composed of a carrier and a working machine (such as a fine spinning machine, a doffing machine of a roving spinning machine, a Shino exchange machine of a spinning machine) or an automatic machine in which the working machine has an integrated carrier function, It moves along the machine edge of a spinning machine group consisting of many spinning machines, decelerates by detecting a work request signal from the spinning machine, and stops at the machine edge after detecting a stop dock provided corresponding to the spinning machine. Then, while repeatedly moving and stopping along the front of the spinning machine,
It is designed to perform certain tasks such as doffing.

When performing work on a large number of spinning machines using such an automatic machine, it has been often used conventionally to consider the time required for each spinning machine of the spinning machine group to perform the work of one spinning machine of the working machine. Then, the so-called taper setup is a method in which the spinning setup is determined in advance so that the work request signal can be output at a fixed time interval. According to this method, the output timings of the work request signals of the spinning machines do not overlap in time, and the working time required for each spinning machine is taken into consideration. Can be used efficiently, and since the work of the spinning machine is carried out in order, there is an advantage that the work associated therewith can be prepared in advance.

However, in this taper setup, when the moving direction is changed at both ends of the spinning machine group and the work is performed in any direction, for example, as shown in FIG. SF2,
When 4,6,8 work in order while moving to the right, change the moving direction, and continue to work on spinning machine SF7,5,3,1 in order while moving to the left, work machine operation When a mistake or the like occurs, the working time per one preset spinning machine is extended. As a result, for example, during the work on the spinning frame SF6, the spinning frame SF is set up so that the work request signal is output next to the spinning frame SF8.
Occasionally, the work request signal may be output from the spinning machine No. 7, and the automatic machine detects the work request signal of the spinning machine SF7, decelerates, and then comes to the spinning machine. , The spinning machine SF8, which was outputting the work request signal first, was postponed, and there was a problem that the work order of taper setup was out of order. In addition, the spinning machine SF7 that should be worked while traveling to the left
On the other hand, if the stop dog detected on the right is not installed, the vehicle will continue to decelerate, the vehicle will decelerate to the next machine, that is, the spinning machine SF8, and the stop dog will be detected and stopped.
There was a problem that the running time was lost.

Means for Solving the Problems In order to solve the above problems, in the present invention, an operation inhibiting member is provided in correspondence with a spinning machine in which a decelerating and stopping operation of the automatic machine is prohibited in a predetermined moving direction of the automatic machine. However, the automatic machine is provided with a prohibition member detection device at a position for detecting the operation prohibition member before the signal detection device of the automatic machine and the output device of the operation prohibition spinning machine face each other in the predetermined movement direction. Equipped with an output device for the release signal, further, after the detection signal input from the prohibited member detection device, until the release signal input,
It is characterized by comprising a traveling control device configured to continue normal traveling regardless of the presence or absence of an input signal from the signal detection device.

Action According to the above, when the prohibition member detection device of the automatic machine detects the operation prohibition member arranged in the spinning machine that prohibits the operation (deceleration, stop) of the automatic machine in the predetermined moving direction, the release signal is input thereafter. Until then, the above operations are not performed regardless of the presence or absence of an input signal from the signal detection device.

Example Hereinafter, a spinning machine group and its doffing machine will be described. As shown in FIG. 3, a plurality of (8) spinning machines SF1 to SF8 are installed in parallel,
It constitutes a spinning machine group G. A rail 1 is laid along the edge of each spinning machine of the spinning machine group G, and an automatic machine 2 including a carrier 3 and a doffing machine 4 is provided on the rail 1 corresponding to the edge of the spinning machine SF1. It is designed to start from the standby station ST of the automatic machine 2 and reciprocate. Each spinning machine is equipped with a controller for controlling the machine base and a spinning amount detector (not shown) that detects the spinning amount of the spinning yarn, so that the spinning cup is close to the appropriate amount for doffing. At this time, a doffing forecast signal is output as a work request signal in the form of lighting a doffing forecast lamp La1 provided at the machine end as an output device. This dodging forecast lamp La1 is station S
The spinning machine SF2, 4, 6, 8 is in the order of the spinning machines SF2, 4, 6, 8 during the rightward movement of the automatic machine 2 starting from T in Fig. 3, and the spinning machine after the automatic machine 2 changes its direction to the left at the group end. SF7,5,3,1 are lit in order, and further, the doffing forecast lamp La1 of the spinning machine to be doffed next by the completion of the doffing of the spinning machine being doffed,
Thus, the output timing of the doffing forecast signal of each spinning machine is set in relation to the winding amount of the spinning cup. Also,
La2 is a doffing start lamp for instructing the start of doffing.

From the pillar 5 of each spinning machine, as shown in FIG.
The support 6 is connected to each other by a connecting bar 7 along the rail 1, and a trolley wire 8 for feeding power to the automatic machine 2 is provided along the rail 1 at the lower part of the support 6. Has been extended.

On the lower surface of the connecting bar 7, corresponding to the spinning machines SF2, 4, 6, 8 which are operated during the rightward movement of the automatic machine 2 in FIG.
The proximity piece 9R for stopping and positioning the automatic machine 2 is fixed, and the proximity piece 9L is fixed corresponding to the spinning machines SF7, 5, 3, 1 which are operated while moving to the left. As shown in FIG. 2, these are arranged with their phases shifted in the longitudinal direction of the spinning machine. Further, auxiliary support members (not shown) are projected from the left and right ends of the connecting bar 7, and limit dogs 10R and 10L for checking the group ends of the spinning machine groups are mounted. In addition, the spinning machine SF7
Will doffing with spinning machines SF2, 4, and 6, and if there is a doffing trouble during this operation, spinning machine SF6 will be used during spinning operation with spinning machine SF6.
Since it is highly possible that the doffing forecast lamp La1 of the spinning machine SF7 will be lit up after that, it is a spinning machine that prohibits the operation (deceleration) of the automatic machine 2 while the automatic machine 2 is traveling to the right. Correspondingly, an operation inhibiting member (limit dog) 11R is attached to the lower surface of the auxiliary supporting member 12 protruding from the connecting bar 7. For the same reason while moving leftward, the spinning machine SF2 is also provided with the operation prohibiting member 11L. These movement prohibition members 1
1R and 11L are attached with different phases in the longitudinal direction of the spinning frame.

Next, the carrier 3 of the automatic machine 2 is provided with a control box 31 on its upper part, and photoelectric detectors (signal detection devices) PH1R and PH1L facing the doffing forecast lamp La1 are provided on the front surface of the doffing start lamp La2. The photoelectric detectors PH2 for detecting light are arranged below and on both sides for right row and left row, respectively. Proximity switches 32R, 32L for detecting the proximity pieces 9R, 9L are mounted on the upper surface of the control box 31 as a stop positioning switch for the right row and the left row in the moving direction of the automatic machine 2 and the front-rear direction, respectively. is there. The proximity switches 32R and 32L perform stop positioning corresponding to right and left rows, respectively, and when one of them operates as a stop positioning switch in a predetermined moving method,
The other acts as an output device of a release signal of a prohibition signal described later. And, in the proximity switch (32L if rightward) that does not act as a stop positioning switch in a predetermined moving direction (for example, rightward), the photoelectric detector PH1R corresponding to the moving direction is the doffing forecast lamp La1 of the spinning machine SF7.
After that, it is attached so as to detect the proximity body 9L. Further, four limit switches LS1 to LS4 are juxtaposed in the front-back direction of the automatic machine 2 on the upper surface of the control box 31, and the limit switch LS1 detects the limit dog 10R attached to the right end of the group G. The limit switch LS2 is for detecting the left limit dog 10L of the group G, the limit switch LS3 is for detecting the right prohibition member 11R, and the limit switch LS4 is for leftward motion prohibition member 11L. Is to detect. The limit switches LS3, LS4 are the doffing forecast lamps La1 of the spinning machine (SF7, SF2 in this embodiment) whose operation is prohibited by the photoelectric detector PH1R (PH1L) corresponding to the right and left rows of the prohibited member detection device. They are arranged at positions where the operation prohibiting members 11R (11L) are detected in front of each other. These detectors, limit switches, etc. are connected to the travel control device 33 in the control box 31.

The traveling control device 33 has a configuration centering on a sequencer, and controls driving of the traveling motor 34 of the automatic machine 2. In the sequencer of the travel control device 33, a travel control program for the automatic machine 2 according to the flowchart of FIG. 4 is stored.

In this flowchart, step 1 is a normal high-speed traveling command output means, step 2 is a predetermined moving direction, whether a prohibition signal is input from a prohibition member detection device (limit switch LS3 or LS4) corresponding to the movement direction. Discriminating means, step 3 is means for discriminating the presence or absence of an input signal from the photoelectric detector PH1R (or PH1L) corresponding to the moving direction, step 4 is discriminating means for coming to the group end,
Step 5 is a means for determining whether or not a prohibition signal release signal has been input, steps 6 and 7 are deceleration / stop command output means,
Step 8 is a traveling direction switching means of the automatic machine 2 which outputs a command to rotate the traveling motor 34 in a direction opposite to the direction of rotation so far.

Next, the operation will be described. The automatic machine 2 stopped at the station ST starts to move by a movement start command when the spinning machine SF2 issues a doffing forecast signal. The automatic machine 2 goes leftward while the control program repeats the determinations in steps 2 to 4.
Then, in step 4, the limit switch LS2 confirms the leftmost limit dog 10L, and in step 8, switches the direction to the right. When the rightward photoelectric detector PH1R detects that the doffing forecast lamp La1 of the spinning machine 2 is turned on (step 3), the traveling motor 34 is decelerated from high speed traveling (step 6), and the rightward proximity switch. The 32R detects the proximity piece 9R and stops (step 7). And dodge start lamp La2
When the photoelectric detector PH2 detects that the light is turned on, the doffing machine 4 moves along the front surface of the spinning machine 2 and is stopped while repeating the doffing. When the doffing is completed, the doffing machine 4 returns to the carrier 3 and heads to the next machine base SF4. In this way, the doffing forecast lamp La1 lights up in order with the spinning machines SF2, 4, and 6 and doffing is performed, but a mistake occurs during the doffing operation up to the spinning machine SF6, and the preset doffing time per unit is When it exceeds, the doffing forecast lamp La1 of the spinning frame SF7 may be lit up after the doffing forecast lamp La1 of the spinning frame SF8 during the doffing operation up to the spinning frame SF6. In this case, the automatic machine 2 moves to the right from the spinning machine SF6 at a normal high speed, and its limit switch LS3 detects the operation inhibiting member 11R at the end of the spinning machine SF7. Then, in step 2 of the flowchart of FIG.
Input to 33, the process proceeds to step 5, the automatic machine 2 continues to run at high speed, and is in a state of waiting for the input of the release signal. While going right, the doffing forecast lamp La1 of the spinning machine SF7 and the photoelectric detector PH1R for right traveling face each other, but the travel control device 33 waits for the release signal in step 5, so the photoelectric detector PH1R Spinning machine SF
Even if it detects that the 7 lamp is lit, this input signal is ignored and the vehicle runs at high speed without issuing a deceleration command. After the photoelectric detector PH1R has passed in front of the doffing forecast lamp La1 of the spinning machine SF7, the leftward proximity switch 32L is moved to the leftward proximity piece 9L.
When the confirmation is made, a cancellation signal is output, and step 5
To step 3. And spinning machine SF while running at high speed
At the end of 8, confirm the lighting of the doff forecast lamp La1 and decelerate and stop.

It should be noted that only the right row photoelectric detector PH1R can be detected during the right row, so the left row PH1L does not detect the lighting of the doffing forecast lamp La1. In this way, even if the doffing forecast lamp La1 of the spinning machine SF7 follows the spinning machine SF8 during doffing work with the spinning machine SF6 due to the delay of the doffing operation, the automatic machine 2 will be Since the vehicle travels at high speed without decelerating the work request signal and without stopping at the machine end and without stopping, there is no movement loss, and the doffing order of the spinning machine does not get out of order.

As described above, according to the device of the present invention, when the forbidden member detecting device of the automatic machine detects the operation prohibiting member disposed in the spinning machine that prohibits the operation (deceleration, stop) of the automatic machine, it is released thereafter. It is possible to prevent the above operations from being performed regardless of the presence or absence of an input signal from the signal detection device until a signal is input.
Therefore, even if a work request signal is detected from a spinning machine that does not require deceleration and stop in the predetermined moving direction of the automatic machine, deceleration traveling or stopping operation is not performed corresponding to the spinning machine. It is possible to eliminate movement loss and taper setup mistakes.
