Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fabric inspection core winding interlocking device that integrally interlocks a fabric inspection section and a core winding section.

Traditionally, long pieces of cloth that have been dyed and sorted are transported by commercial transport vehicle to a fabric inspection machine, where the fabric is run upwards or downwards at a constant speed on an inclined inspection board. The inspected fabric was then transferred to a core winding machine, measured to a certain length, made into tube core winding or Andon core winding, and then transported out.

Attempts have been made to integrate the fabric inspection machine and the core winding machine, but each of these fabric inspection and winding mechanisms had the following drawbacks.

In other words, ■ For products that require the fabric to be rolled up in advance before inspection, a winding device is required before inspection, and there is also a limit to the length of the fabric, which varies depending on the type of fabric. may not be available.

■ Even if the inspection section and the winding section are driven separately, the adjustment range of the fabric tension is limited by the equipment function in terms of synchronization between the two sections. It is difficult or impossible to deal with various operations such as raising and lowering the speed of the winding section, forward/reverse inching, and instantaneous stopping, and cases where the winding section changes over a wide range depending on the type of cloth, degree of finishing, thickness, etc.

■ There are many adjustment points and requires skilled personnel for operation.

■ Requires multiple operators and cannot be operated by one person.

■ There are restrictions on the types of urocloth that can be handled, as well as restrictions on the sewing method and quantity of core wrapping, and the style of wrapping that maintains the product price.

■ Requires a large space for installation.

In particular, it is difficult to synchronize the fabric inspection part and the core winding part from start to stop. As shown in the figure, the fabric inspection machine and the core winding machine are arranged in series and separated from each other, and a buffer section that requires a large floor space is installed between them to temporarily stagnate the fabric in the fabric inspection area. There wasn't.

The present invention overcomes the above-mentioned drawbacks, and enables the inspection section and the core winding section to be perfectly synchronized without any trouble in any operating range.
This invention provides an interlocking machine for inspection core winding.

In other words, the present invention has the configuration described in the claims, so that during startup and inching, the running speed of the fabric in the inspection section increases faster than the running speed of the fabric in the core winding section, which causes the fabric to loosen. On the other hand, there is no possibility that excessive tension will be applied to the fabric due to the running speed of the fabric in the inspection section increasing later than the running speed of the fabric in the core winding section. There is no occurrence of so-called hunting, where the speed of the fabric on the opposite side repeatedly increases faster or later than the speed of the fabric on the core winding, and the speed reaches a predetermined running speed once and runs at a constant speed. Even when moving to fabric inspection and core winding work at high speeds, the speed difference between the two parts will fluctuate, and as mentioned above, the fabric may become slack, receive excessive tension, or cause hunting fluctuations in tension. without doing anything,
The speed of the fabric inspection part and the core winding part can be maintained so that a constant tension is always applied to the fabric regardless of the operating speed throughout the entire fabric inspection core winding operation from starting, inching, and stopping. Alternatively, depending on the type of cloth, if it is necessary to reduce the tension as the winding diameter increases during the core winding process, the tension can be changed at a predetermined rate.

As mentioned above, during core winding work, it is necessary to maintain a predetermined tension at all times, although it varies depending on the type of cloth, the shape of the core winder, etc., and if the tension decreases from this predetermined one turn, the cloth will loosen and the winding shape will change. Disturbances and wrinkles occur, and proper core winding is not possible. On the other hand, if too much tension is applied to the cloth, it may cause the edges of the cloth to be cut, the fabric to be bulky to be crushed, and winding wrinkles, etc., resulting in the cloth being loosely core wound. If the tension becomes too large during the process, it may cause various problems such as unevenness of the winding β, which is called a shank, or hunting in the tension, such as unevenness of the sides of the core winding. The interlocking device of the present invention completely eliminates the occurrence of these troubles.

In addition, the present invention employs a center drive type core winding system in which the speed of the cloth at the core winding section increases as the winding diameter increases, and therefore the tension of the cloth increases. The rate of decrease in the rotational speed of the core winding portion, which decreases the rotational speed as the core winding speed increases, can be easily adjusted depending on the type of cloth, and the tension of the cloth can be maintained at a predetermined level depending on the form of the winding.

On the other hand, the measuring device detects that the length of the core winding fabric has reached a predetermined length, the winding fabric is cut and removed, the next core is attached to the winding shaft, and the next fabric inspection is carried out immediately. It is necessary to move on to the core winding work, but unless the braking time from the end of the measurement to the stop is shortened as much as possible, excess cloth will be wound up, resulting in measurement errors and wasted time. However, by adjusting the braking force in the interlocking device of the present invention, the time from completion of this measurement to stopping can be kept to a minimum, and furthermore, when starting, It has a function that prevents danger to workers due to fluctuations in speed, tension, etc. during transient periods such as stopping and forward/reverse driving, and eliminates malfunctions due to back electromotive force in the electric circuit. It was possible to do so.

As a result, as shown in Figure 1, we were able to create an integrated inspection core winding interlocking device that even an unskilled person could easily, safely, and reliably operate with a short period of training. It is.

Hereinafter, the conventional machine and the present invention will be described in detail based on drawings, block diagrams, motor characteristic curve diagrams, etc.

As illustrated in FIG. 2, in the past, a fabric inspection machine 50 and a core winding machine 5
1 were arranged in series with a conveyor 36 etc. in between.

The fabric inspection machine 50 has an electric device capable of forward/reverse operation and drive operation, and has a guide roll 31 mounted on the frame 41.
．． 32, a measuring roll 33, a press roll 34, a known manual reset type automatic counter 56 with an auxiliary contact for measuring the tailoring length, an inclined inspection table 35, etc. are installed,
A structure in which a brake-equipped electric motor 42 whose rotational speed can be adjusted by a mechanical transmission and a measuring roll 33 are connected and driven by a chain or belt 44 has been used.

In the illustrated example, the conveyor 36 and the electric motor 42 are connected and driven via a chain or a belt 37.

Further, the auto counter 56 is driven by a chain from the measuring roll 33.

The core winding machine 51 has an electric device with a reverse brake that can be operated in forward and reverse directions, and has a guide roll 38, a swivel tension 57, and a core winding tension bar 39 on a frame 52.
, a winding shaft 40, etc. is attached, and an electric motor 43 whose rotational speed can be adjusted by a mechanical transmission and the winding shaft 40 are connected and driven by a chain or (four belts 45). .

When the fabric inspection machine 50 and the core winding machine 51 are used for operation, the woven fabric that has been finished by the separately provided dyeing and arranging machine is deposited on the transport vehicle 10 as a heaped woven fabric and inspected. The reverse machine 50 is carried under the idle roll 31.

As shown in the figure, this cloth 46 is in contact with the guide rolls 31 and 32, is pulled out between the measuring roll 33 and the press roll 34 which are properly attached to each other, surrounding the measuring roll 33, and is placed on the inspection table 35. The cloth 47 is sent down to the conveyor 36, and is collected on the conveyor 36 like cloth 47.

The fabric inspection worker Ct stands at the position Ml on the scaffold 53, performs fabric inspection work facing the fabric inspection table 35, and sets the required length on the auto counter 56 according to the tailoring.

If necessary, operate the operation panel 54 on the scaffolding 53 to start, stop, drive, increase or decelerate, automatically stop at the set count, and cut the edge of the cloth indicating the winding cut position with a knife at this cut position. After loading the auto counter 56 again
Reset and repeat inspection work one after another.

The cloth 43 connected to the cloth 47 is wound around the winding shaft 40 in the core winding machine 51, surrounding the guide roll 38, swivel tension 57, and core winding tension bar 39.

The core winding operator stands at position M2 on the floor and holds the cloth 48 on the winding shaft 4.
The cloth is wound into a 49-shape on the cloth 49, the specified cut mark is confirmed by measuring the length, and the core winding machine 51 is wound at the position where it is wound to the tailoring length.
The finishing winding 24 is removed from the winding shaft 40 and placed on the pallet 23, and the cut end of the cloth 48 is newly wound around the core. winding machine 51
and move on to the next core winding work.

While the core winding machine 51 is stopped, the cloth 47 is accumulated on the conveyor 36,
During operation of the core winder 51, this accumulation decreases.

The core winding operator adjusts the speed of the core winder 51 depending on how much fabric 47 is accumulated on the conveyor 36, and this adjustment is performed using the operation panel 55.

This configuration requires a large floor area to install the fabric inspection machine 50, conveyor 35, and core winding machine 51, and requires two workers, and requires coordination between the two for acceleration/deceleration, starting, and stopping. Therefore, a certain level of operational skill was required.

FIG. 1 shows the inspection core winding interlocking device of the present invention, and it is clear that the installation floor space is significantly smaller than that shown in FIG. 2.

The measuring roll 3 and the electric motor 12 may be connected directly or via a reduction gear.

In the core winding section 21, the winding shaft 10 is connected to and driven by a decentralized separately excited DC motor 13 via a chain or a belt 15.

The winding shaft 10 and the electric motor 13 may be connected directly or via a reduction gear.

The fabric 18 taken out from the piled fabric 17 on the transport vehicle 16 is
It moves around the guide rolls 1 and 2, the measuring roll 3, and the press roll 4, and is pulled out by frictional contact with the cylindrical surface of the measuring roll 3 and the nip between the measuring roll 3 and the press roll 4. 5 to reach the guide roll 6, further surround the guide roll 7, tension roll 8, and guide roll 9, reach the winding shaft 10, and be wound up to form a wrapped cloth 19.

During the aforementioned running, the cloth 18 is subjected to a force in the running direction by the measuring roll 3 and the press roll 4, and is subjected to a predetermined measuring force by the measuring device 22 connected to the measuring roll 3 via a chain and a gear mechanism. The length of one roll is measured, and it is inspected while running diagonally down on the inspection table 5, and core-wound around the winding shaft 10 while maintaining a constant tension to complete the finished roll 24. .

The winding shaft 10 and the winding core are connected to each other when the core winding portion rotates in the direction of core winding, and are disconnected when the core winding portion rotates in the opposite direction, such as in reverse drive. The punching is coupled by a mechanism called a core metal, for example, a device that is composed of a roller, a ball, etc. that can move in a groove provided in the winding shaft 10, and can couple the core-wound tube core only in one direction.

The worker is at position M in FIG. 1, and is inspecting the fabric 18 running down the inspection table 5. At S, when the wrapped fabric 19 has been completed as the finished wrapping 24 and the machine automatically stops, The finished winding 24 is separated and removed from the cloth 18 from the winding shaft 10 of the inspection core winding interlocking machine, arranged on the pallet 23, a new winding core is attached to the winding shaft 10, and the end of the cut cloth 18 is After winding, the inspection core winding interlocking machine is restarted using the operation panel 25, and the next inspection core winding operation is started.

If necessary while the cloth 18 is running, the interlocking device can be stopped, driven in forward and reverse directions, and restarted by operating the operation panel 25 at any time.

Also, depending on the tailoring, automatic measuring and stopping devices may not be used.
Manual core winding measurement with a meter is also possible.

The finishing winding 24 can be wound with a tube core as shown in FIG. 7A, or with an andon core as shown in FIG. This can be set using the operation panel 25, and it is also possible to create a reverse ticket with the winding direction reversed by changing the attachment of the core metal and by changing the winding direction switch.

The inspection core winding interlocking machine according to the present invention is configured to automatically stop when the finished winding 24 of a predetermined length is completed, as will be described later. Capable of core winding work, starting, stopping,
The drive etc. can be carried out very easily by operating the operation panel 25, and even unskilled persons, regardless of age or sex, can operate it safely as long as they have received basic operational training.

Next, the configuration of the electric control circuit of the inspection core winding interlocking machine according to the present invention will be explained.

As shown in FIG. 3, the inspection roll 3 of the inspection section 20 in FIG. 1 is driven by a motor IM, which is a primary electric ball controlled variable speed induction motor.

The winding shaft 10 of the core winding section 21 is driven by a motor DCM which is a decentralized separately excited DC motor.

The AC current for driving the electric motor IM is supplied from the AC power source by the fuse,
It is supplied via a circuit breaker, etc., a triac circuit, and a forward/reverse switch.

The motor for driving the cooling fan of the motor IM is separately driven by an alternating current supplied from an AC power source through a fuse or the like.

The driving current for the electric motor DCM is supplied from the AC power supply to the SIRISC circuit via the operation switch, where it is converted to DC, and is supplied to the armature of the electric motor DCM via a fuse and a forward/reverse switch.

The control circuit for each electric motor is operated by pushbuttons PB on the operation panel circuit.

Control circuit The control side of the medium-sized motor IM includes an operation panel circuit, an operation support circuit, a speed setting circuit, an acceleration/deceleration adjustment circuit, and an amplifier circuit AMP.
1. Combined with the triac circuit, the operation auxiliary circuit also goes through the drive setting circuit and drive priority circuit to the amplifier circuit AMP.
1, the dynamic brake circuit to the amplifier circuit AMP1 and the forward/reverse switch, the ink clock circuit to the forward/reverse switch, and the forward/reverse switch to the interlock circuit to the operation auxiliary circuit. On the other hand, the operation assist circuit is connected not only to the above-mentioned ink lock circuit but also to an ink lock circuit on the motor DCM control side, which will be described later.

A control current is separately supplied to the speed setting circuit from an AC power source via a fuse or the like.

A measuring circuit consisting of a measuring roll and an automatic counter, which are driven by an electric motor IM via a reduction gear, is coupled to an operation panel circuit.

The control side of the motor DCM is connected to the operation panel circuit, the core limit switch LS, the operation switch circuit, the control power rectifier circuit, the tension setting circuit, the preamplifier circuit, the amplifier circuit AMP2, and the cyrisk circuit, and the armature of the motor DCM. The current circuit is connected to the tension detection circuit and the preamplifier circuit.

On the other hand, the field rectifier circuit is separated from the Cyrisk circuit and reaches the field circuit.

A forward/reverse switch circuit is separately coupled directly from the above-mentioned run switch circuit, and this forward/reverse switch circuit is further interconnected with the above-mentioned ink clock circuit, and this ink clock circuit is also interconnected with a dynamic brake circuit of the electric motor DCM. has been done.

Next, one drive characteristic curve diagram of the electric motor will be explained.

FIG. 4 shows the drive characteristics of the inspection section drive motor IM, and shows the relationship between drive speed and time.

The driving speed, such as Vl and (2), is maintained at a value that varies depending on the fabric inspection, the type of cloth to be core-wound, and the degree of finishing.

Normally, the speed is set faster for white fabrics and slower for darker colored fabrics, and the setting of this one drive speed is performed in a speed setting circuit as described later.

In addition, the al2 a2 and a3.24 curves change from the stopped state of zero speed to the above-mentioned Vl and v2 when starting the interlocking machine.
Showing different acceleration curves until reaching the driving speed,
In order to prevent the tension applied to the fabric stretched between the two parts due to the difference in acceleration performance between the inspection part and the core winding part during startup and acceleration, and to prevent the fluctuation thereof, an acceleration/deceleration adjustment circuit as described below is installed. Selection adjustment is made in .

al 2 a22 a3 ) The acceleration decreases in the order of a4.

vi is a drive speed, and the speed and acceleration during driving are set in advance by a drive setting circuit described later.

FIG. 5 shows the drive characteristics of the core-wound chamber dynamic motor DCM, and shows the relationship between drive speed and time.

The relationship between the driving speed and the winding diameter of the core winding also shows a substantially similar curve.

In the figure, the time axis is on a logarithmic scale.

The rising curve a in the curve is determined by the characteristics of the electric motor, the inertia rate of the core winding portion, etc.

The highest point of the curve v1. v2. v3. V4 etc. are determined by the speed of the cloth running in the fabric inspection section mentioned above, and the tension of the fabric stretched between the fabric inspection section and the core winding section is the tension set by the tension setting circuit described later. The maximum speed is reached at the point where Wl, W2°W3. The speed decreases along a curve such as W4.

When the cloth is thin with a tube core, the drive follows the v1W1 curve, when the cloth is medium-thick, it follows the V2W2 curve, and when the cloth is thick, it follows the v3W3 curve.In the case of Andon core winding, it is driven at a lower speed, following a curve such as the V4W4 curve.

Figure 6 shows one of the characteristic curves shown in Figures 4 and 5, the drive characteristic curve of the inspection part drive motor IM and the core winding chamber dynamic motor DCM when the drive speed is V. The motor IM is drawn with the highest positions of the curves coincident, and the electric motor IM is driven along the ABGD curve, and is divided into an AB starting acceleration section, a BG constant speed section, and a GD deceleration/stop section.

The electric motor DCM is driven along the curve of AFCD, and the AF
It is divided into the starting acceleration part of , the deceleration part of FC (during which the cloth runs at constant tension and constant speed), and the deceleration and stop part of CD.

In the interlocking machine of the present invention, the starting acceleration portions AB and A
The accelerations of F are made the same, the tension of the cloth is kept constant during this period, and after the speed of the cloth reaches a predetermined value (for example, Vl), the motor IM is set at a constant speed, and the motor DCM is set at a constant speed and tension of the cloth. The vehicle gradually decelerates as if the vehicle is traveling at 1 drive, and when stopping, the time ts← until the GD and CD decelerate to a stop is set.

Note that the case where the acceleration is higher on the AE side than AB is shown.

The driving speed is also listed, but the motor DCM
A curve in which the acceleration of reverse drive is low is shown, but during this period, as mentioned above, the connection between the winding shaft and the winding core is released by the one-way clutch, and the entire valve is driven by the reverse drive of the electric motor IM. This indicates that the range is within the range.

Next, the operation of each block circuit in the block diagram of FIG. 3 will be explained.

Regarding the related circuits of the electric motor IM, the driving alternating current is AC.
The power supply reaches the triac via the fuse, the primary voltage is controlled by the gate pulse of the amplifying/oscillating circuit AMP, which will be described later, and passes through the forward/reverse switch to reach the electric motor IM, where it is rotated in a predetermined forward/reverse direction. Drive with speed.

The speed of the electric motor IM is detected by a coccometer generator TG, and the signal is fed back to a speed setting circuit, where it is compared with a reference speed preset in the circuit, and an amplifier circuit M is used to maintain this predetermined speed. A gate pulse is generated at , and this pulse is applied to the triac to maintain the speed of the motor IM at a constant value.

The triac can of course replace the scales with a pair of cyrisks in opposite directions.

Regarding the drive circuit of the motor DCM, alternating current from the AC current is rectified in the SIRISK circuit to become direct current, which reaches the motor DCM via a forward/reverse switch that is synchronized with the forward/reverse switch of the motor IM, and converts it into a specified forward/reverse direction. 1 drive at a predetermined speed in the direction of .

The core winding is finished as a tube core winding as shown in Figure 7A, or as an andon core winding as shown in Figure 7B, and usually one winding is 30 to 120 yards long, and the finished winding is based on the core diameter. The diameter ratio is usually 5:1 and sometimes even 10:1.

Therefore, in order to keep the tension applied to the cloth constant in core winding by center drive, as shown in Figures 5 and 6, as the winding diameter increases, the tension applied to the cloth in Figure 1 is approximately inversely proportional to the winding diameter ratio. It is necessary to reduce the rotational speed of the winding shaft 10.

This change in tension as the rotation speed decreases is detected by a tension detection circuit, which will be described later, and the detection signal is fed back to the preamplifier, where it is compared with a reference tension signal preset in the tension setting circuit. A gate pulse is generated in the amplifier circuit AMP2 by the signal current from the AMP2, and this pulse is applied to the sirisk to maintain the speed of the electric motor DCM at a predetermined tension.

The tension detection signal described above can also be obtained by detecting the position of a tension roll provided in the travel path of the cloth, but in the embodiment described later, it is detected by the armature current of the electric motor DCM.

Starting and stopping of the entire interlocking device is performed by push button PB on the operation panel.

In the apparatus of the present invention, the core metal limit switch LS is not activated and the electric motor DCM cannot be operated unless the core metal is attached to the winding shaft 10 shown in FIG. 1.

In the motor IM quantity relation circuit, the operation assist circuit operates a forward/reverse drive setting circuit and an ink clock circuit, which will be described later, between the motor IM and the motor DCM.

As mentioned above, the speed setting circuit is a circuit that maintains a predetermined speed by feeding back the signal from the coccometer generator TG. This is a circuit to maintain speed.

On the one hand, the acceleration/deceleration adjustment circuit adjusts the V1. ■A predetermined acceleration is applied to the electric motor IM until the operating speed as shown in 2 is reached, and as mentioned above, one of the speed increase curves shown as al 2 a2 and a37 a4 in Fig. 4 is selected. This circuit is designed to match the point at which the electric motor IM reaches a predetermined rotational speed with the selected winding speed point in the speed increase curve of the electric motor DCM as shown in FIG. AF in FIG.
The function is to match the speed increase curves of both types of motors as shown in the curves, and to operate the dynamic brake circuit and the ink clock circuit of both types of motors when the motors are stopped.
It is also possible to not take on the role of deceleration adjustment to match the time ts until sudden stop as shown in the curve and the GD curve.

The operating speeds such as vl and {circle around (2)} mentioned above vary depending on the type of fabric to be core-wound, and are usually faster for thin fabrics, such as the speed v1 at the top of the W1 curve in FIG. 5, and faster for W2. The speed at the top of the W3 curve V22 is set slower as the material becomes medium-thick and thick like V3.
The speed at the top of the curve is set even slower, such as V4.

The speed and acceleration of the forward and reverse drives are similarly set to curves as shown in FIGS. 4 and 6 by a separate drive setting circuit.

When driving a machine for checking sewing methods or fabric inspection defects, it must be possible to operate the machine efficiently at the appropriate speed regardless of the movement of the acceleration/deceleration regulator, so the drive priority circuit is designed for that purpose. It is a circuit.

If the drive priority circuit requires reverse, forward, or reverse drive,
This circuit is capable of direct movement and sudden stopping at the low speed set by the drive speed setting circuit, regardless of the speed setting circuit and acceleration/deceleration adjustment circuit that set the cloth speed, and the interlocking machine according to the present invention has a predetermined path. This circuit is necessary when stretching the cloth all the way through the winding shaft I, when winding the cloth around the winding shaft, and during fabric inspection work.

The dynamic brake circuit is a circuit that applies dynamic braking to stop the armature of each motor at a predetermined deceleration when stopped, and a measuring device is used to confirm that the fabric has been wound to a predetermined length. This circuit is necessary to stop the cloth immediately after it has finished, and to adjust the tension of the cloth when the cloth is stopped.

The in-clock circuit mainly consists of a timer circuit with delayed opening contacts, and includes a relay that opens the dynamic brake circuit at a delayed time when stopped.By providing this circuit, it is possible to prevent failures that cause triac and cyrisk punctures due to back electromotive force. We were able to eliminate all occurrences.

The measuring circuit consists of an autocounter driven by the measuring roll. After reaching a predetermined rotation speed, the attached microswitch is closed or opened, and this signal is transmitted to the operation button to activate the interlocking machine. This will cause the system to stop.

The control power supply rectifier circuit is a circuit that generates a predetermined DC value that is a reference for tension setting, and the tension setting circuit is a circuit that obtains a DC value that corresponds to the predetermined tension.

, the tension detection circuit uses the armature current of the motor DCM,
This is a circuit that detects the tension of the cloth stretched between the inspection section and the core winding section, and as mentioned above, the signal is compared with the set electrostriction from the tension setting circuit in the preamplifier circuit. , the signal from this preamplifier causes the amplifier AMP
At 2, a gate pulse is generated to control the cyrisk,
Speed and therefore tension adjustment of the motorized IcM takes place.

As a result, as shown in FIGS. 5 and 6, vertical T'% characteristics are obtained in which the rotational speed of the winding shaft decreases as the winding diameter increases,
The rate of this speed reduction varies depending on the thickness of the fabric; thin fabrics show the W1 curve, medium weight fabrics show the W2 curve.
Thick fabrics tend to have a speed reduction curve such as the W3 curve, and in the case of andon winding, a speed reduction curve such as the W4 curve is required.

The drive motor for the fabric inspection section is not limited to triac or thyrisk control, but any variable speed induction motor with primary electric ball control that can maintain and adjust a constant cloth feed speed can be used. As the drive motor for the section, any separately excited DC motor that can perform speed control not only by Cyrisk control but also by the stationary Leonard set armature control method that can maintain and adjust a constant cloth tension may be used. Of course, this can be done.

Since the present invention has the configuration described in the claims, it is compact and does not require a large installation space. The operator can perform core winding work automatically while inspecting the fabric by himself, and is not limited by the type of fabric or tailoring, and can also perform tube winding. Andon winding is also possible, and the degree of winding can be controlled freely, and during operation, it is possible to stop, reverse, drive in forward and reverse directions at will, and there is no disturbance in the winding during that time, and the machine can be restarted.

Therefore, the safety of operation and the reliability of operation are high, the finished winding does not cause wrinkles in the finished product, and the finished winding has a uniform winding end and no complaints can be obtained.
Since the operation is easy, no special intuition or skill is required, and since the braking force is strong until the machine stops after the measurement is completed, the machine does not run unnecessarily, so it does not cause overruns known as measurement deviations. , there is no breakdown due to back electromotive force or noise generated in the electric circuit, it has excellent resistance to changes in temperature and humidity, you can freely select the front and back designs, and the length of the design can be adjusted.
