Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention uses an inverter motor as the main motor, and enables the speed of operation to be adjusted during operation.In particular, by rotating at a low speed during yarn exchange, thread exchange is ensured. This invention relates to an electronically controlled sample warping machine that can perform the following tasks.

(Prior art) As a sample warping machine conventionally used,
The structure disclosed in Japanese Patent No. 9-29242, that is, the hollow shaft 1
A driving shaft 2 and a driven shaft 3 are protruded from the center of both ends, and a small toothed ring 5 fixed to a pulley 4 is fixed to the driving shaft 2, and a thread guiding rod 6 is fixed to the driven shaft 3 at the other end. The small toothed wheels 7 are loosely mounted, and the small toothed wheels 5 and 7 are interlocked by the meshing of the small toothed wheels 9 and 10 at both ends of the interlocking shaft 8 in the hollow shaft 1, and the hollow shaft is connected to the driven wheel 2. The hollow shafts of the three driven wheels are supported by one side, and the hollow shafts of the three driven wheels are hooked around the rotors 15 at both ends by the arcuate portions 11 of the trunk frame 13 and 14, which have the same outer periphery with alternating arcuate portions 11 and straight portions 12. A warping cylinder A is formed by passing a cross beam 16 attached with a conveyor belt 17 that is moved by sliding over the cross beam 16 surface.
The conveyor belt 17 is driven by a drive element 2 which is screwed into a spiral shaft 20 of a planetary gear 19 which is rotated all at once by meshing with a master gear wheel 18 which is appropriately driven from outside the body.
1, the same amount of fine movement can be achieved at the same time, and the guiding rod 6
The structure of a sample warping machine (the reference numerals are the same as those used in the embodiments described later) is known, in which the tip of the warping cylinder A is bent inward to face the upper surface of the front end of the warping cylinder A as a yarn guiding part 6'. There is. This sample warping machine was evaluated as being able to warp more uniformly and better than other types of warping machines. In such conventional sample warping machines, a punch card is used to warp the handle, and each device or mechanism is operated according to instructions from the punch card to warp the desired handle. be. However, the work of punching punched cards requires a lot of time and the occurrence of punching errors is unavoidable, so improvements are desired.
The applicant of the present application has already proposed an electronically controlled sample warping machine that enables handle warping by electronic control in Japanese Patent Application No. 199590/1982, and has received very good reviews.

However, since this electronically controlled sample warper uses a normal motor as the main motor, it is not possible to adjust the rotation during operation, and miscatch and mischange occur when changing threads. This method has the disadvantage that thread breakage is unavoidable and easy to occur, and furthermore, it is not possible to perform buffer start/stop (slow start, slow stop) or jogging operation, and there is still room for improvement in terms of operational efficiency. Ta. That is, the rotation speed of the thread guide rod 6 depends on the rotation speed of the electric motor, but since the electric motors currently used are equipped with a transmission and a clutch brake, the rotation speed of the thread guide rod 6 at the time of starting and the thread During the cutting process, the clutch and brake are operated alternately to perform so-called inching rotation, but since the gear ratio is set at the warping speed, alignment is extremely difficult. Also, during warping, the rotational speed of the thread guide rod during thread change work and thread winding work is the same and cannot be adjusted, so it is rotated at a low speed during thread change work, where mistakes are likely to occur, and warping is performed. It was not possible to rotate the thread guiding rod 6 at a high speed during winding work to improve work efficiency, and the rotation speed was adjusted to match the rotation speed during thread changing work.

In particular, special yarns that tend to break due to the tension applied during the yarn change operation must be wound at a considerably low speed, resulting in a lot of wasted work.

(Problems to be Solved by the Invention) The present invention was invented in view of the above-mentioned points, and uses an inverter motor as the main electric motor to enable adjustment of the operating speed during operation, as well as buffer start/stop and jogging operations. The electronic control system enables high-speed changes in thread tensioning speed, facilitates alignment of the starting surface, and ensures reliable thread change by rotating at a low speed especially when changing the thread.

FIG. 15 is a block diagram showing a characteristic configuration of the present invention. A controller (sequence board) 79 connected to a program setting device 78 and a sensor 67C sends ■operation stop signal, ■jogging signal, ■multi-stage shift signal, and ■forward/reverse signal to inverter I during thread change work. The operation stop signal is turned on, the multi-speed change signal is turned on, and the forward/reverse rotation signal is turned on (normal rotation), and the inverter motor 46 is rotated at a low speed set in advance with the setting device of the inverter I. On the other hand, during thread I@ work, the operation stop signal is turned on, the forward/reverse rotation signal is turned on, and the inverter motor 46 is rotated at a high speed, which is also set in advance with the setting device of the inverter I.

Therefore, it is possible to prevent the occurrence of mischanges, thread breakages, and miscatches during thread exchange as much as possible, and it is also possible to speed up the thread wrapping operation.

The operation will be explained below using the above configuration.

First, the number of threads 22 differs depending on the pattern of the sample, but for example, a different color thread bobbin of n colors is placed on the creel B and the required number of threads 22 is pulled out, the guide plate 24, the tension adjuster 25,
Pass the dropper ring 26 and unsorted guide 27, and press and set on the base Y with a permanent magnet thread stopper E. Then, simultaneously with the operation of the main body, the yarn guide section 6' moves circularly on the warp body by a program setter 78 according to a pre-prepared arrangement, and threads the yarn 22 onto the conveyor belt 17.

The conveyor belt 17 also moves in the direction of the arrow due to the action of the inner screw shaft 20. As the pulley 4 rotates, the slit plate 28
generates a pulse and operates the circularly arranged rotary solenoid 29.
When the unsorted guide 27 attached to the guide rods 30 and 31 is advanced to the operating position and passes through the thread guiding section 6°, the thread 22 stretched between the guide rods 30 and 31 is caught and wound onto the conveyor belt 17.

The thread removing device 3
2, the thread 22 being wound is removed, and another system is wound according to the next instruction from the program setting device 78.

To explain the movement of the yarn 22 at the time of yarn change with reference to FIG. 9, the yarn 22a, which is initially held by the unsorted guide 27 in its original position, moves to the operating position as the unsorted guide 27 rotates. When the yarn advances, it is in the state 22b, and from this state it is attached to the warping cylinder A by the yarn guiding section 6', and -
The thread 22c is in the wound state, and the second and subsequent attempts are made in the state of the thread 22d. When the thread 22d being wound is removed by the thread removing device 32, it returns to the state of the thread 22b. The unsorted guide 27, which has rotated and advanced to the operating position in order to catch the removed yarn, has its tip 27a located within the recess r of the stopper plate S, so that the removed yarn 22b is not properly selected. It is ensured and smoothly caught by the unsorted guide 27, and accidents such as double winding do not occur.

At this time, thread 221 is scheduled to be removed! I] When the thread guiding rod 6 passes through the thread loosening prevention device 60, it is immediately detected by the sensor 67b, and the rotary solenoid 66 is turned on by signals from the program setting device 78 and the controller 79, and the rotating disc body 62 is moved by the spring means 64. It is rotated in a direction opposite to the direction of the biasing force, and the thread 22 located in the thread restraining notch 63 is pressed down by the end face of the thread restraining notch 63 and the stopper 65. In this pressed state for a short time, the tapping thread guiding rod 6 is connected to the sensor 67.
When the position 3 is reached, the problem is resolved and the thread loosening prevention device 60 is on standby in preparation for when the next thread is removed.

After the removed yarn is pressed down by the rotating disc body 62, the unsorted guide 27 is returned to its original position while being tightened without loosening due to the weight of the dropper ring 26, and is sequentially set in a predetermined manner in anticipation of the next instruction from the program setting device 78. It is wound according to the arrangement.

In addition, when winding, the twilling levers 33, 34, 35 and 37 perform a twilling action, and the cut twilling bars 36 and 38 distinguish the twilled yarn into lower and upper yarns, and the wound series is divided into the lower and upper yarns. Cuff) The twilled yarn is cut at the cutting part by the action of the twill bars 36 and 38, the lower yarn is stopped by the thread stopper 39 attached to the trunk frame 13, and the upper yarn is caught by the skeleton 40 of the rewinding machine C. The cloth is tied to the cloth through the roller 41 and then wound up. The warping cylinder A of this embodiment is almost circular, so the winding of the skeleton 40 is omitted and the woven fabric beam 49 is wound back through the rollers 44.
It has the advantage that there is no problem even if it is wound up to 9.

The control method and operation of the electronically controlled sample warping machine of the present invention will now be explained based on FIG. 10-3-yj. The program performs parallel processing in which steps from a to j are sequentially repeated at intervals of about 0.5 to 1 millisecond.

The bottom is grooved with four types of bars.

A solenoid is attached to the tip of each bar, and by the operation of each solenoid, the threads wound on the warping cylinder A are sorted into the upper and lower parts of each traverse bar to form twills and cut twills. The twill at the start can be selected using the twill up switch and twill down switch.

In the twill removal method when the thread is not being replaced, the warping machine is in operation,
When it is confirmed that the count value is "0" (the number of turns display is "0"), the three types of traverse upper solenoid and cut traverse upper and lower solenoid are ON, and the photoelectric C (67c) turns the traverse upper solenoid and cut traverse upper and lower solenoid OFF. becomes. At the same time, when the lower twill indicator light becomes ONL count "0" (number of turns display "0'"), when the lower twill indicator light becomes ONL count "0" (number of turns display "0"), the lower twill solenoid and cut twill upper and lower solenoid are activated. Three types are ONL, and photoelectric C (67c) turns off the twill lower solenoid and cut twill upper and lower solenoid.At the same time, the twill upper indicator light turns ONL.
, repeat the above at the next count "0" (number of turns display "0").

In the twill removal method during yarn change, each solenoid operates for an extra one rotation (during the thread change) in the above-mentioned twill removal method not during yarn change.

C1 Total number counter Count circuit This is a circuit that turns the amplifier signal of the total number counter into 0N10FF.When the current value is reset to "0" (number of turns display "0"), the amplifier signal of the total number counter turns ON and the photoelectric C (67C) turns OFF and increments the total number counter.

d. Total number completion stop circuit When the total number counter reaches the set value, the total number completion indicator light turns on. This total number completion indicator light ON signal is connected to the warping machine main body stop switch on the circuit, and the warping machine also stops. Cancellation is performed using the reset switch of the total number counter itself.

e, Conveyor belt left moving circuit and f, Conveyor belt right moving circuit The conveyor belt of the sample warping machine of the present invention is not endless but moves left and right by the movement of the drive element 21, so the start position and winding position of the conveyor belt can be adjusted. It can be moved independently by using the left movement switch and right movement switch. Also, for safety, a belt right limit switch and a belt left limit switch are installed at the right and left limits. The conveyor belt 17 is stopped when the belt left switch/notch is operated when moving in the left direction, and when the belt right limit switch is operated when moving in the right direction.

g. Run/stop circuit This is a circuit that transmits the rotation of the main electric motor &LL 6 to the guiding rod 6. Operation SW (switch) ON, stop SW, 1 after ON
A second timer is inserted, but this is to synchronize with the program that determines whether the machine is running or not.

h. Yarn select circuit This circuit controls the yarn select (thread selection) and yarn removal solenoid.

i. Yarn restraint solenoid circuit This is a circuit that turns the yarn restraint solenoid 0N10FF, and the yarn restraint solenoid is ON only between photoelectric B (67b) and photoelectric A (67a) after the change signal for yarn selection is turned ON.

j1 Number of windings counting circuit This circuit counts and displays the number of times the yarn is wound around the warping cylinder A.The number of windings display is incremented by 1 due to the output of the photoelectric A when the thread is not being selected, and when the number of windings exceeds the number of windings set value. It is reset and the number of turns display becomes "0".

Next, as a specific example, two threads, a red thread and a white thread, are used, and by repeating two red threads and two white threads, the total number of threads is 3.

Also, writing,
Equipped with a switch to select operation and call operation.
During operation, it is possible to display preset contents and display the operating state, and when called up, it is possible to modify the program and the operating state. This program setting device 78 is connected to a controller 79 via yarn type, yarn change, and count up signals, and sequentially repeats a preset program while transmitting and receiving these signals. The content of the program uses four arithmetic formulas, for example, 10 yarn types 1, 5 yarn types 2, 7 yarn types 3, and after repeating these three times, yarn type 4. The program to wind 6 yarns and 2 yarn types 5 is (lx
10+2x5+3x7)+4x6+5x2. Of course, use () many times 6) + 3
A program called X5 can also be produced. Furthermore, once a program is set, it is protected by a backup battery unless the program is changed. The controller 79 is a part that controls the main body of the warping machine, and according to the program set by the program setting device 78, the electromagnetic switch relay 81 connected to the controller 79, the thread [E O
-n Solenoid relay 82, thread select, thread control,
It controls the thread buzz solenoid relay 83, twill upper, twill lower, cut sewing upper, cut sewing upper solenoid relay 84, display lamp 85, etc. The electromagnetic switch relay 81 controls 0N10FF of the winding motor, and the yarn type Q-n solenoid relay controls the yarn O to n solenoids when the yarn selection relay is ON, and the yarn
The thread scraping relay controls the thread pressing and thread buzzing solenoids, and the relays for twill pick-up, twill pick-down, cut twill top, and cut twill bottom solenoid control the twill pick-up top, twill pick-down bottom, cut twill top, and cut twill top solenoids, respectively. It is something to do. The display lamp 85 is a lamp that displays the operating status of the warping machine body, and includes power ON, belt movement to the right, belt movement to the left, twill removal up, twill removal down, main motor ON, 2 windings, total number of warping, number of windings, etc. There is a lamp. The operation switch 86 is a switch that controls the warping machine main body, and controls the power supply, warping morph automatic stop, number of winding settings, belt movement stop, belt right movement,
These include belt movement to the left, twill removal up, twill removal down, main motor ON, main motor OFF, two-winding reset switch, total number of winding counters, etc. The photoelectric switch 67 includes three photoelectric switches or sensors 67a, 67b,
67c, and is located on a circumference divided into approximately three equal parts in order to take timing of yarn selection, yarn sagging, yarn shedding, twill removal, cut twill, count-up, etc. The double winding stop switch 87 detects that two or more threads attached to the creel stand are wound at the same time, and sends a signal to the controller 79.In addition, it turns off the clutch in the warping machine body. Thread breakage detection switch, various solenoids controlled by the group of relays, electromagnetic switches,
Equipped with mischange display, etc.

The operation of the sample warping machine of the present invention is shown in a time chart as shown in FIG.

In this time chart 1, two two-turn windings of yarn type O are wound, two two-turn windings of yarn type 1 are wound, and this is repeated thereafter. The two turns here is the value set by the number of turns setting switch which can be set from 0 to 19 turns. The signals from the three photoelectric switches are photoelectric A,
They are named Photoelectric B and Photoelectric C, and the operation is assumed to start from between Photoelectric switch A and Photoelectric switch B, as follows: Photoelectric B - Photoelectric C - Photoelectric A - Photoelectric B - Photoelectric C -
It is used to sequentially generate photoelectric charges A and take the timing described below. The count signal is charging A)28
It is transmitted every time the passage of a is detected, and only once after the change signal received from the program setting device is received, the guiding rod 6 is
I don't make a call because it's running idly. Each time the count-up signal reaches the set value of the number of windings, it is turned ON between photoelectrics A to C, incrementing the total number counter and sending the count-up signal to the program setting device. The change (thread exchange) signal is synchronized with photoelectric A and is sent from the program setting device, and is a signal used when changing the yarn type. The select signal is a signal for transmitting the signal to the yarn type Q-n solenoid when any one of the relays for the yarn type Q-n solenoid is ON. At the start, it is on from the start to photoelectric C, and after that, confirm that a change signal has arrived, and then switch from photoelectric A to the next photoelectric A.
ON for a short period of time and OFF for a short period of time (10 to 50m5)
F, it immediately turns ON, and remains ON until the next photoelectric C. The timing of the yarn type O1 yarn type 1 solenoid relay is adjusted by the controller based on the yarn type setting signal sent from the program setting device, and remains ON until a select signal for changing the yarn is generated. After confirming that the thread buzz solenoid signal has received a change signal,
It is ON between photoelectric A and photoelectric C, and the thread buzz solenoid signal is photoelectric B after the thread buzz solenoid signal is turned ON.
- Stays ON during photoelectric A. The twilling upper solenoid signal and the twilling lower solenoid signal can be started from either side using the twilling upper and twilling lower switches, but on the condition that they are turned ON alternately, the count-up signal is used from the start to photoelectric C, not at the time of change. After confirming that the signal is ON and that a change signal has come, the signal is turned ON during photoelectric C after passing from photoelectric A to photoelectric C once. Although not shown in the time chart of FIG. 12, when either the twill up solenoid signal or the twill down solenoid signal is ON, the cut sewing up solenoid and the cut twill up solenoid signal both turn ON.

Furthermore, by changing the timing of the twill removal upper and twill removal solenoid signals, it is also possible to perform different types of twill removal that can be directly rewound onto the fabric beam 49. The warper body starts operation with the start switch and stops with the stop switch, but in addition to the two-winding stop switch that checks if two or more threads are being wound at the same time, the warper does not wind any threads when changing. It can also be stopped by a mischange signal that informs the state, a total number completion signal sent from the total number counter that indicates that the total number of threads has been wound, a thread breakage detection signal that indicates thread breakage, etc.

The low speed rotation of the inverter motor 46 during thread change, which is a characteristic effect of the present invention, will be explained with reference to the flowchart shown in FIG. The program setting device 78 connected to the controller (sequence board) 79 determines that the change signal outputted in synchronization with the sensor 67a at the time of thread exchange is turned on, turns on the multi-speed change signal (low speed signal), and switches the inverter. The motor 46 is rotated at low speed. Next, set the number of idling while checking the on/off signal of the sensor 67c connected to the controller (sequence board) 79, keep the multi-speed shift signal on during that time, and turn off the multi-step shift signal when the idling stops. , the inverter motor 46 is rotated at high speed. After that, the robot returns to the starting position and repeats the above operation. The flowchart in FIG. 16 shows the case where the idle rotation is performed twice.

Note that the on/off control of the jogging signal and the forward/reverse signal is controlled by a known external switch, so a description thereof will be omitted.

In the above explanation, the yarn types are 0 to n, but n is usually up to 9, but it can be more than that. 0 turns is explained as 1 to 19, but it is not limited to this. Of course. The relay part, which is part of the driver of the solenoid, may be made of a semiconductor such as a transistor or a silice. The various switches for photoelectric A, photoelectric B, and photoelectric C may be magnetically responsive elements, mechanical limit switches, etc., and the controller at this stage is a microcomputer, memory, TTL, CMO.
5. Although it is formed using a photocoupler or the like, a general-purpose sequence controller may also be used.

(Effects of the Invention) As described above, the present invention uses an inverter motor as the main motor, thereby making it possible to increase and decrease the speed during operation, Fik impulse erection stop/stop jogging operation, and high-speed thread attachment speed. In particular, when changing the thread, the operating speed is reduced to eliminate mis-catches and the thread change can be reliably performed, which is a significant effect.
