Description

Description: FIELD OF THE INVENTION The present invention relates to a method for preventing a collision between a cross roll being wound at a mounting position on a loom and a completed roll being wound at a temporary position. It is about.

[Prior Art] In Japanese Patent Laid-Open No. 62-215403, a cross roll unwound from a loom is transferred by a cross roll carrier, sorted and sorted by automatic control, and stored in a stocker. Has become.

Further, JP-A-64-52851 and JP-A-64-52852 disclose this type of transfer control system. In this control system, transmission of the deceleration and command of the transport vehicle, transmission of the cross roll identification index and stock address, and completion of the transfer operation are performed, and the arrival of the transport vehicle to the calling loom, the execution of the transfer operation, and the transfer from the calling loom. Automation of transportation and transfer such as starting to a stocker, arriving at a destination stocker, and the like is achieved.

[Problems to be Solved by the Invention] The wound cross roll is moved to a temporary placement position on the loom side, and the empty cross roll is mounted on the loom while the winding roll in the completed winding position is temporarily placed on this temporary placement position. It is installed in the position and new weaving is started. Therefore, when the diameter of the empty cross roll increases, the cross roll in the completed winding position on the temporary placement position and the cross roll on the mounting position interfere with each other. Therefore, the cross roll in the completed winding state is removed from the temporary placement position, smooth transfer by the cross roll transport vehicle is hindered, and transport control is hindered, and efficient transport control cannot be achieved. Also, normal weaving becomes impossible.

It is an object of the present invention to provide a method of preventing a cross roll before completion of winding at a mounting position on a loom from colliding with a cross roll in a completed winding position at a temporary placement position.

[Means for Solving the Problems] Therefore, in the first aspect of the present invention, the cross roll in the completed winding state in which the transport vehicle for transporting and transferring the cross roll is moved from the cross roll mounting position on the loom side to the temporary placement position When the transfer is completed, the transfer control data is transmitted from the control unit of the transport vehicle to the control unit of the calling loom, and the winding operation is performed on the cross roll mounting position before the control unit of the calling loom receives the transfer completion data. When the diameter of the cross roll before the completion reaches a predetermined diameter, the operation of the loom is stopped.

In the second invention, the cross roll in the completed winding state is temporarily placed on the temporary placement carriage, and at least the temporary placement carriage equipped with the cross roll in the completed winding state stands by at the transfer standby position. Until the transfer completion data is received, the reverse traveling of the temporary trolley to the calling loom side is prohibited.

[Operation] When the winding of the cross roll on the loom side cross roll mounting position is completed, the cross roll in the completed winding position is moved to the temporary placement position and the empty cross roll is mounted at the cross roll mounting position. In this state, the operation of the loom is restarted, and the cross roll carrier is called. After the carrier arrives at the calling loom, the cross roll in the completed winding position on the temporary placement position is transferred to the carrier, and when the transfer is completed, the transfer completion data is sent from the controller of the carrier to the control of the calling loom. Sent. If the cross roll diameter before the completion of winding on the cross roll mounting position reaches the predetermined winding diameter before receiving the transfer completion data, the operation of the loom is stopped, and the predetermined winding diameter is reached when the transfer completion data is received. If not, the loom continues to operate. Collision between the old and new cross rolls can be avoided by appropriately setting the predetermined winding diameter.

When the temporary roll position of the cross roll in the completed winding state is on the temporary carriage, at the time when the temporary roll carrier waits at the transfer standby position at least with the cross roll in the completed winding state, the temporary locomotive calling loom side Is prohibited. Then, this prohibited state is maintained until the control unit of the calling loom receives the transfer completion data. Therefore, before the cross roll on the temporary carrier is transferred to the carrier side, the temporary carrier is moved to the loom side. It will not move towards the side and avoid collision between old and new cross rolls.

FIG. 12 shows a management computer C, a repeater 9, a loom 1, 1A,
Cross roll carrier control panel 11 and cross roll carrier 2
11 is a flow chart showing the respective functional operations and the relationship between them, and FIG. 11 is a flow chart showing a transfer control program and a cross roll collision prevention program in the loom control computers C ₁ and Ca ₁ and the carrier control computer C ₂ . Hereinafter, the cross roll conveyance control, transfer control, and cross roll collision prevention control will be described with reference to both flowcharts. It should be noted that the text inside the symbol "" in FIGS. 11 and 12 and the following description is each control unit (9,11, C, C ₁ , Ca ₁ , C ₂ , C ₃ ).
Represents information that is preset or generated in each control unit (9, 11, C, C ₁ , Ca ₁ , C ₂ , C ₃ ).

By the way, the repeater 9 scans each loom sequentially and the warp breakage taken into the loom control computers C ₁ and Ca ₁ ,
The "M data" such as the machine stop or the number of weft insertions related to the occurrence of weaving defects such as weft breakage and weft insertion error is temporarily stored and then transferred to the management computer C.

When the cross roll 36 is completely wound up by a certain loom (for example, 1A), the loom control computer Ca ₁ outputs a winding completion signal from a cross counter (a surface roller rotation amount detecting device for detecting the cross roll winding amount). Is displayed on the display unit 40 on the basis of. The operator stops the loom based on the confirmation of the winding completion display, and turns on the transfer call button 39 on the loom 1A for calling the cross roll carrier 2. Reference numeral 43 denotes a call cancel button.

Call button loom control computer Ca ₁ in response to the transfer command by ON operation 39 to set the "cross transport vehicle calling mode" and the registration frame C. The registration frame C indicates a registration undetermined state of the cross data and the identification index. Further, the loom control computer Ca ₁ prepares for counting the origin signal input from a rotary encoder (not shown) for detecting the machine rotation angle position, that is, for starting the weft insertion count (hereinafter referred to as pick count). The weaving density is preset in the loom control computer Ca ₁ , and the winding diameter of the cross rolls on the cross roll mounting positions 1c and 1d can be grasped based on the set weave density data and the pick count data. The winding diameter of the cross roll may be grasped only by the pick counter.

When the repeater 9 is scanned, the loom control computer
Ca ₁ responds to this scan and sends "M data" to relay 9
Send to. The "M data" includes information on "call crossing vehicle call" setting and registration frame C setting. The repeater 9 searches the “M data” for the “cross transport vehicle calling mode” and whether or not the registration frame C is set,
If "Cross guided vehicle calling mode" is set, "Cross guided vehicle calling" is set to the cross roll guided vehicle control panel.
11, and if the registration frame C is set, prepares for the transmission of "calling a cross carrier" to the management computer C.

When a “command request” is transmitted from the management computer C, the repeater 9 transmits “cross-carrier call” to the management computer C. The management computer C creates an identification index based on the reception of "calling a cross carrier", and adds the identification index to "cross data" including information such as warp break, weft break, and weft insertion error.
The "cross data" is transmitted to the repeater 9. The repeater 9 immediately calls the received "identification index + cross data" and looms.
The data is transmitted to the loom control computer Ca ₁ of 1A, and the loom control computer Ca ₁ displays the identification index and the cross data on the display unit 40 based on the reception of the “identification index + cross data”.

“Cross carrier call” includes the number of the call loom 1A, and the cross roll carrier control panel 11 controls the loom number display lamp group 11a shown in FIG. It instructs the calling loom 1A to turn on the display lamp corresponding to the calling loom 1A, and transmits a "start report C" to the repeater 9. Repeater 9 transmits a "start report C" on the basis of the received "start report S" to the loom control computer Ca _1, the loom control computer Ca ₁ is "start report S" in response to receiving the "start report response" While transmitting to the repeater 9,
Commanding ON the deceleration command transmitter 12b next to the deceleration stop command post 12 of the top side of the loom column (preparation chamber R ₃ side in FIG. 1).

The repeater 9 sets the "cross carrier call mode" based on the reception of the "start report response" to the cross roll carrier control panel 11
Send to. Cross roll conveyance vehicle control panel 11 via the optical communication device 14a to the transport vehicle control computer C ₂ cross roll transport vehicle 2 waiting in the home station 14 based on the received "cross transport vehicle call mode""startorder"
Send As a result, the cross-roll carrier 2 waiting at the home station 14 starts moving toward the call loom 1A. It contains "start instruction" to the guide wire pickup instruction data and call the loom number, the guided vehicle control computer C ₂ slide into the pickup guide wire L _3, based on the guiding line pickup instruction data and call the loom number .

When the cross-roll carrier 2 is not waiting at the home station 14, the arrival of the cross-roll carrier 2 at the calling loom 1A is delayed than usual. Even when the cross roll carrier 2 is waiting at the home station 14, the arrival at the calling loom 1A may be delayed more than usual depending on the calling order.

The cross-roll carrier 2 decelerates by receiving the lighting light of the deceleration command transmitter 12b in the lighting state in front of the calling loom 1A, and receives the lighting light of the stop command transmitter 12c of the calling loom 1A to receive the light. Stop at the transfer work position in front of 1A. In this stop position, the optical communication device 2a of the cross-roll transport vehicle 2 and the optical communication device 12a of the deceleration stop command post 12 can face each other to exchange information, and the stop command receiver 2
The optical axes of c and the stop command transmitter 12c are in the same state.

After the weaving machine is stopped, the worker can use the bearings 1c, 1d (that is,
The completed cross roll 36 on the cross roll mounting position) is cut and placed on the stand portions 25a and 25b of the temporary carriage 25 at the stocking standby position shown in FIG. Then, the cross counter described above is reset.

When cross roll 36 is transferred to the provisional table vehicle 25 side, the limit switch Ls ₄ is turned ON. The loom control computer Ca ₁ invalidates the ON signal of the limit switch Ls ₁ based on the ON signal, and the motor 28 becomes operable. Note that the motor 28 may be configured to be always operable.

When the temporary placement carriage 25 is moved to the retracted position in FIG. 7 by turning on the reverse command button 38, the limit switch Ls ₃ is turned on by the positioning dog 35, and the temporary placement carriage 25 is stopped at the retracted position. In this state, the worker enters between the temporary trolley 25 and the loom 1A and attaches the empty cross roll 41 to the cross roll mounting positions 1c, 1d.
Attach to.

After the cut end of the woven fabric W on the loom 1A is connected to the empty cross roll and the temporary placing cart 25 is brought to the transfer standby position shown in FIG.
Ls ₂ is turned on by the positioning dog 34, and the temporary placement vehicle 25 stops and waits at the transfer waiting position. This stop standby is grasped by the loom control computer Ca ₁ based on the normal rotation stop of the motor 28 and the ON state of the limit switches Ls ₄ and Ls ₂ . Then, the operation of the loom is restarted by turning on the start button 46 on the loom 1A.

The loom control computer Ca ₁ turns on the reverse drive command button 38 when it recognizes that the temporary carriage 25 has waited at the transfer standby position.
The signal (that is, the reverse command signal) is invalidated. In addition,
In this case, the ON signal of the forward command button 37 (that is, the forward command signal) may be invalidated together. As a result, even when the command button 37 or 38 is turned on, the temporary carriage 25 equipped with the cross roll 36 in the completed winding state does not move forward and backward, and the empty cross roll on the cross roll mounting position
41 and the cross roll 36 on the temporary carriage 25 in the completed winding state
And will never clash. Therefore, the cross roll 36 does not fall off the temporary carriage 25 and the weaving is not hindered. Further, the fact that the reverse command signal is invalidated (including the case where the forward command signal is invalidated) can be displayed by a display lamp or a function panel to notify the operator.

The operator decides whether or not to inspect the cross roll 36 based on the identification index and the cross data displayed on the display unit 40, and inputs the destination stocker number to the loom control computer Ca ₁ by operating the input operation unit 42. input. The loom control computer Ca ₁ takes in the input destination stocker number as a part of the identification index and changes the “M data”.

When cross-roll transport vehicle 2 arrives stops the call loom 1A, the guided vehicle control computer C ₂ transmits the "arrival report" to the loom control computer Ca ₁ call loom 1A. The "arrival report" includes the loom number of calls loom 1A, the loom control computer Ca ₁ is based on the "arrival report" receiving collates the loom number. If they match, "collation matching" is transmitted to the carrier control computer C ₂ of the cross roll carrier 2, and if they do not match, an alarm is issued.
Then, the loom control computer Ca ₁ sends the deceleration command transmitter 12b
Turn off the light and clear "Call crossing vehicle". The guided vehicle control computer C ₂ prepares for the transmission of the "transfer preparation" from the loom control computer Ca ₁ based on the reception of the "matching match".

“Preparation for transfer” represents the state data on the loom side, which includes the presence / absence of the cross roll 36 on the temporary carrier 25, the position of the temporary carrier 25, and the presence / absence of cancellation of calling of the carrier vehicle. The loom control computer Ca ₁ sends the “transfer preparation” at that time to the carrier vehicle control computer C ₂ after sending “matching match”, and thereafter changes to the carrier vehicle control computer C ₂ at every change of “transfer preparation”. The prepared "transfer preparation" is sent. "Preparation for transfer" indicates the transfer prohibited state when the cross roll 36 does not exist on the temporary carrier 25, the temporary carrier 25 does not exist at the transfer standby position shown in FIG. This is the case where even one of the states with call cancellation has occurred.

If the call cancellation button 43 after cross-roll transport vehicle 2 had left the home station 14 is turned ON, is transmitted to the transport vehicle control computer C ₂ cross roll transport vehicle 2 arrives stopped calling loom 1A " “Transfer preparation” includes information indicating that the call is canceled, and “transfer preparation” indicates that transfer is prohibited. As a result, the carrier vehicle control computer C ₂ transmits “transfer completion” to the loom control computer Ca ₁ .

Even if the call cancellation is not performed, if the cross roll 36 is not on the stand portions 25a and 25b of the temporary trolley 25 (that is, the limit switch Ls ₄ is not in the ON state), the temporary trolley 25 is not at the transfer standby position. Case (ie limit switch Ls ₂ is O
If it is not in the N state), “transfer preparation” indicates that transfer is prohibited, and the carrier control computer C ₂ issues a transfer start command until “transfer preparation” is transmitted, which indicates transfer permission. Absent.

No call cancellation, limit switch Ls
₄ , When Ls ₂ is turned on, “preparation for transfer” representing this state is transmitted from the loom control computer Ca ₁ to the guided vehicle control computer C ₂ . The transport vehicle control computer C ₂ issues a transfer start command based on this "transfer preparation", and the cross roll 36 causes the transfer arm 44 and the transfer hand 45 of the cross roll transfer vehicle 2 to move as shown in FIG. It is transferred onto the transfer hand 45 by the linking operation. As long as this during transfer sent from the loom control computer Ca ₁ "transfer ready" is changed to transfer prohibition, the guided vehicle control computer C ₂ transfer operation based on the "transfer ready" Ban and issue an alarm.

Based on this alarm, the operator turns on the manual operation mode command button 47 on the cross roll carrier 2, and the carrier control computer C ₂ manually operates the automatic operation mode of the transfer operation in response to the ON signal of. Switch to mode. Based on this manual operation mode, the transfer operation of the cross roll carrier 2 is manually returned to the initial position, and then the automatic operation mode command button is pressed.
The ON operation of 48 causes the guided vehicle control computer C ₂ to switch from the manual operation mode to the automatic operation mode. After the cause of the abnormality is resolved following the return to the automatic operation mode, the guided vehicle control computer C ₂ commands the forced transfer based on the ON operation of the forced transfer command button 49, and the forced transfer is performed. Be seen. After the forced transfer is completed, the guided vehicle control computer C ₂ transmits “transfer completed” to the loom control computer Ca ₁ .

The loom control computer Ca ₁ performs pick count in the operation of the loom after the empty cross roll 41 is installed,
This pick count number is stored in advance in the loom control computer Ca ₁
When the “transfer completion” is received by the loom control computer Ca ₁ before reaching the pick count number N set for the loom control computer Ca ₁ , the loom control computer Ca ₁ issues a command to continue the operation of the loom 1A and The invalidation of the ON signals of the command button 37 and the reverse command button 38 is released. If the measured pick count number reaches the set pick count number N before “transfer completion” is received by the loom control computer Ca ₁ ,
The loom control computer Ca ₁ gives an instruction to stop the operation of the loom and gives an alarm.

The diameter of the empty cross roll 41 on the cross roll mounting positions 1c, 1d is gradually increasing, and if there is a cross roll 36 on the temporary carriage 25 at the transfer standby position unless the weaving is stopped, both cross rolls 41, 36 will eventually interfere.
The reason why the completion of the transfer of the cross roll 36 on the temporary carriage 25 is delayed is, for example, the occurrence of the transfer error as described above, or the time until the cross roll carrier 2 arrives at the calling loom 1A from the time of calling. There is a case that it is hanging. If such cross rolls interfere with each other, the cross rolls 36 on the temporary trolley 25 will fall off, or good weaving will not be possible. However, even when the cross roll 36 is present on the temporary carriage 25, the diameter of the cross roll 41 on the cross roll mounting positions 1c and 1d is set on the temporary carriage 25 by setting the set pick count number N appropriately. The weaving can be stopped before the cloth rolls 36 interfere with each other, and the interference between the old and new cross rolls 41 and 36 can be avoided.

After the transfer is completed, the loom control computer Ca ₁ clears the pick count number based on the reception of “transfer completed” and changes and sets the registration frame C to the registration frame R. The "transfer completion" signal in this case is sent when the limit switch Ls ₄ of the temporary carriage 25 is turned off or when the cross roll carrier 2 completely transfers the cross roll. Signals can be used.

The registration frame R indicates the registration state of the cross data and the identification index. Then, the loom control computer Ca ₁ sends a "start permission" including the destination stocker number to the guided vehicle control computer C ₂ , and the guided vehicle control computer C ₂ confirms and stores the destination stocker number based on the reception of the "start permission". Command to start. With this, the cross roll carrier 2 is designated as the stocker (3, 4 or 5)
Start towards. Then, "M including the registration frame R
Data “scan”, “command request” transmission / reception, loom 1A
The "cross registration mode" including the loom number and the destination stocker number is transmitted / received, and the final identification index is registered and stored.

After that, the cross roll carrier 2 is moved to the destination stocker (3,4
Alternatively, after arrival at 5) is stopped, transmission / reception of “arrival signal” between the stocker control computer C _{3 of} the stocker (3, 4 or 5) and the cross roll carrier 2, transmission / reception of “transfer preparation”, “transfer completion” Based on the “transmission / reception,“ return permission ”transmission / reception, the cross-roll carrier 2 transfers and returns to the home station 14. Then, after the cross-roll carrier 2 returns to the home station 14, a “return report” is transmitted to the cross-roll carrier control panel 11, and the cross-roll carrier control panel 11 is turned on based on the reception of the “return report”. A command to turn off the loom number display lamp 11a in the state is issued.

In the above embodiment, the origin signal counting method of the rotary encoder for detecting the machine rotation angle position is adopted as a means for grasping the diameter of the cross roll 41 on the cross roll mounting positions 1c and 1d, but instead of the rotary encoder. An embodiment is also possible in which the diameter of the cross roll 41 is grasped by using the above-mentioned cross counter or by measuring the time after the operation is restarted. Further, the invention of grasping the diameter of the cross roll at the position where the cross roll is mounted can be applied to a loom that temporarily puts the cross roll in a completed winding state at a fixed temporary position.

It is also possible to carry out the pick count in the above-described embodiment from the time of calling to the "transfer completion".

[Effects of the Invention] As described in detail above, the first aspect of the invention is when the cross roll transport vehicle completes the transfer of the wound roll completed cross roll that has been moved from the cross roll installation position on the loom side to the temporary placement position. The transfer completion data is transmitted from the control unit of the carrier to the control unit of the calling loom, and before the control unit of the calling loom receives the transfer completion data of the cross roll before completion of winding on the cross roll mounting position. When the diameter reaches the predetermined diameter, the operation of the loom is stopped, so that the diameter of the cross roll on the cross roll mounting position becomes large enough to interfere with the cross roll on the temporary placement position. Without
As a result, it is possible to avoid a situation in which the cross roll is dropped or the weaving is not possible due to the interference between the two cross rolls.

A second aspect of the invention is to control the calling loom from the time when the cross roll in the completed winding state is temporarily placed on the temporary placement carriage, and at least the temporary placement carriage equipped with the cross roll in the completed winding state stands by at the transfer standby position. Until the unit receives the transfer completion data, it is configured to prohibit the reverse movement of the temporary trolley to the calling loom side, so that it is possible to prevent the interference of both cross rolls due to the movement of the temporary trolley, It is possible to avoid a situation in which the cross roll is dropped or the fabric cannot be satisfactorily weaved due to the interference of both cross rolls.

Claims (2)

[Claims] 1. A control unit for a transport vehicle when the transport vehicle for transporting and transferring the cross roll completes the transfer of the cross roll in the completed winding state, which has been moved from the cloth roll mounting position on the loom side to the temporary placement position. Sends the transfer completion data to the control unit of the calling loom, and before the control unit of the calling loom receives the transfer completion data, the diameter of the cross roll on the cross roll mounting position before the completion of winding reaches a predetermined diameter. A method for preventing cross roll collision in a loom, in which case the operation of the loom is stopped. 2. A transfer vehicle for transferring and transferring cross rolls is moved from a cross roll mounting position on the loom side to a temporary placement carriage capable of traveling in the forward and backward directions, at the time when transfer of the cross rolls in a completed winding state is completed. The transfer loom control unit transmits the transfer completion data to the control unit of the calling loom, and the control unit of the call loom is operated at the time when at least the temporary placement carriage equipped with the cross roll in the completed winding state waits at the transfer standby position. A method for preventing cross roll collision in a loom, wherein reverse movement of the temporary carriage to the calling loom side is prohibited until the transfer completion data is received.
