Abstract

PURPOSE:To keep a beltlike material in an approximately horizontal state and to improve its quality and productivity by installing a deflection quantity detecting means between a feeding means and a pulling means of the material and keeping the deflection quantity within a proper range. CONSTITUTION:A titled dystem consists of a beltlike material 2 feeding means, means 28-30 installed at the downstream of the feeding means and used for detecting the 1st deflection quantity of the material 2 and the 2nd deflection quantity larger than the 1st one, a means for pulling the material 2, and a control means. The above-mentioned control means increases the deflection quantity in response to an output from the means 28-30 by keeping a feeding speed at the 1st speed as it is when the deflection quantity reaches the 1st deflection quantity. Further, the feeding speed is increased to the 2nd speed to decrease the deflection quantity when the deflection quantity reaches the 2nd one. Thus the material 2 is kept in an approximately horizontal state by the system mentioned above without being influenced by an unreasonable tensile or compressive stress, and its quality and productibity are improved.

Description

[Detailed description of the invention] In the technical field, Sadaaki Ki has developed a shaft 1 for press O-roll processing, etc.
This invention relates to a system for feeding and supplying elongated strips of material having various shapes such as 11 sides (new faces, for example circular).

Conventional technology A typical prior art is shown in FIG.

Hoop-shaped strip material 2 wound around uncoiler 1
For example, it can rotate freely, is pulled by a leveler 3, and is supplied to a processing device 4 such as a press or roll processing.

The strip-shaped material 2 in the uncoiler l is rotated freely and thereby deflects as indicated by reference numeral 2a.

The leveler 3 has a pair of rollers 6 driven by a motor 5 and a plurality of rollers 7 for guiding, and sends out the strip material to a processing device (side 4 side). A roller 8 is provided, referenced 2
Stretching the strip of material resulting in the deflection indicated by b;
Performs processing such as press and roll processing. On the downstream side of the leveler 3, a detection means 10 is provided for detecting the amount of deflection of the deflection portion 2b.

This deflection detecting means 1O includes a rabbit detector 11 that detects the upper limit position slightly below the tension position i'' of the deflection portion 2b, and a second detector 12 that detects the upper limit position of the deflection portion 2b that is below the tension position i''.
and has. ” When the biting portion 2b is detected by the second detector 12, the motor 5 and the feed roller 6 are stopped. In this state, in the processing device 4, the tension roller 9
Processing is performed while the flexible portion 2b is being pulled and supplied. As a result, the bending portion 2b becomes the first detector 11
When detected, the motor 5 and feed roller 6 of the leveler 3 feed the strip-shaped material to the processing device 4 side again. Therefore, when the amount of N8 increases and the deflected portion 2b is detected by the second detector 12, the motor 5 and the feed roller 6 are stopped again.

The leveler 3 smoothly supplies the strip material 2 to the processing device 4, and the strip material 2 is r
aJ allows it to be supplied horizontally. Therefore, a relatively long distance is required between the leveler 3 and the processing device 4. In addition, a bending portion 2a is formed so that the leveler 3 can pull the strip material 2 from the uncoiler 1 and send it smoothly to the processing device &4, and therefore the distance between the uncoiler 1 and the leveler 3 is relatively long. I have no choice but to do it. In this manner, in the prior art, each of the four corners of the uncoiler 15, leveler 8, and processing device 4 is relatively long, requiring a large installation space in a factory. Along with this, the bending portion 2a.

In order to prevent workers from coming into contact with 2b, safety fences must be provided over relatively long distances between the uncoiler l and the leveler 3 and between the leveler 8 and the processing device 4. This increases equipment costs. Further, the leveler 3 pulls the strip-shaped material 2 to send it out, or stops sending it out. Therefore, it is difficult for the processing device 4 to process the strip-shaped material continuously at high speed. Moreover, to make matters worse, there is a problem in that compressive stress is applied to the strip-shaped material 2 by the feed roller 6, and the quality of the product processed by the processing device 4 is degraded. When the surface of the strip material 2 is made of a particularly soft material, such as aluminum, or when the surface must be prevented from being scratched as much as possible, the leveler 3 and processing equipment M4 may To prevent damage during tension or compression,
A protective layer is previously attached to both surfaces of the strip material 20, and after the processing is completed by the processing device 4, the protective layer is removed. Therefore, productivity will be extremely reduced.

Purpose The purpose of Kisadaaki is to improve productivity by making it possible to continuously supply and process strip-shaped materials, and to do so without applying undesired tensile or compressive forces to the strip-shaped materials. , so that you can get high quality products ;(
Our objective is to provide a single-feeding system for belt-shaped materials such as sheet press and roll processing.

Embodiment: (g) Figure 2 is an overall system diagram of an embodiment of the present invention. Material 2 is motor 2
It is sent to the leveler 3 side by the power of 0. Leveler 8

Qi Kai [@Figure. Motor 2 installed on leveler 3
First, it is an induction motor, which is driven to rotate at a rotational speed dependent on the frequency of electric power supplied via a switch 39 from a frequency conversion circuit F@38 such as an inverter. Three-phase AC power is supplied to the frequency conversion circuit 38 via a switch 40 .

Switch 39.40 is rendered conductive by energizing relay coil 43.44 of relay 41.42. relay coil 4
3 is connected in series with a normally conductive switch 45 and an emergency cutoff switch 47 of a relay 46.

An operation switch 48 and an emergency cutoff switch 49 are connected in series to the relay coil 44 . Frequency conversion circuit 38 has two input terminals 50, 51. A high level signal is applied to the input terminal 50 via the relay switch 54 of the relay 52, which causes the frequency conversion circuit 38 to set the motor 21 to a first high frequency, e.g.
Provides 5H2 power. When a high level signal is applied to the other input terminal 51 via the relay switch 56 of the relay 55, the frequency conversion circuit 38
is supplied with power at a second lower frequency, for example 30'Hz. Relay coils 57.58 of relays 52.55 constitute an interlock circuit together with relay switches 59.60. A first detector 83.84 is connected in connection with the relay switch 59.60, and further connected to the relay 52.84.
55 relay switches 61 and 62 are connected. Second detectors 35 and 36 are connected in parallel to the relay coil 6B of the relay 46, and are connected in series.

The bent portion 2d is ;I'! ; In the down position tU, which is located between the dollar output device 33 and the second detector 34 and where the switch 45 is conductive, the relay coil 43 is magnetized to M1. This makes the relay switch 39 of the relay 41 conductive. When the operation switch 48 is operated, the relay coil 44 is excited, and the relay switch 40 of the relay 42 becomes conductive. The strip material 2 is stretched and processed by the processing device 4, and when the bent portion 2d is detected by the first detector 8BVC, its contact 33a becomes conductive. This excites the relay coil 57 of the relay 52. Therefore, the relay switch 54 becomes conductive, and the frequency conversion circuit 3
A high level signal is applied to the input terminal 50 of No. 8. The frequency conversion circuit 38 drives the td motor 21 to rotate at high speed. As a result, the leveler 3 sends out the strip-shaped material 2 to the processing bag M4 so that the amount of "grabbing" of the "grabbing portion 2d" is increased. As the amount of deflection of deflection=7+partial portion 2d increases, even if the contact B 3 a of the first detector 33 is cut off, the relay coil 57 remains FJy magnetized by the self-holding action of the relay switch 61. Therefore, even after the deflected portion 2d is no longer detected by the first detector 8B, the motor 21 continues to supply the leveler 33 and the strip material 2 to the processing device 4 at high speed.

] When the amount of deflection of the pinched portion 2d gradually increases and the deflected portion 2d is detected by the second detector 34, the contact point 34
b blocks it. Therefore, at the same time as the self-holding of the relay 52 is released, the contact 34a becomes conductive, the relay coil 58 of the relay 55 is excited, and the relay switch 62 causes the self-holding. Relay switch 56 of relay 55
gives a high level signal to the input terminal 51 of the same wave number conversion port 1@88. Due to this force, the same wave'#, conversion circuit 3
8 rotates the motor 21 at a low speed. motor 21
By rotating at a low speed, the speed at which the leveler 8 feeds the strip material 2 to the processing device 4 becomes low IFL, and the amount of deflection of the deflection portion 2d gradually decreases. Even after the deflection portion 2d is no longer detected by the second detector 34, the motor 21 continues to be driven to rotate at a low speed due to the self-holding action of the relay switch 62, and the leveler 3 continues to feed out the strip material 2 at a low speed. In this way, the leveler 3 always continues to supply the strip-shaped material 2 so long as the amount of deflection of the biting portion 2d is within the range of the deflection amount detected by the first detector 33 and the second detector 34, respectively. Therefore, the processing device 4 can perform press/roll processing, etc. by smoothly pulling the 18th pinched portion 2d having a small amount of pinching. Therefore, not only productivity is improved, but also undesired tensile stress and compressive stress are not applied to the bent portion 2d, and quality is improved. Furthermore, by shortening the distance between the leveler 3 and the processing device 4, the installation space of the factory can be reduced.

When the pinched portion 2d abnormally tilts upward Vc4 or bends abnormally downward due to a malfunction of the processing device 4, the amount of deflection of the bent portion 2d is detected by the third and fourth detectors 85.36. be done.

This demagnetizes the relay coil 63 of the relay 46. Therefore, relay switch 47 is cut off, and relay 41
The relay coil 43 is demagnetized. Therefore, the relay switch 39 is cut off, and the leveler 3 is stopped due to the motor 21 being stopped.
supply will be stopped.

Although the above description has been made in relation to the deflection amount detection means 32 and the leveler 3 and processing device 4, such a configuration may also be implemented in relation to the deflection amount detection means 27 and the uncoiler 1 and the leveler 3. Ru. Due to this expansion, the amount of deflection of the narrow portions 2c and 2d of the strip material 2 is suppressed to a small value, and the strip material 2 from the uncoiler I can be smoothly supplied to the processing device 4 while remaining substantially horizontal.

d, Figure 15 is an enlarged view of an embodiment of the pond of the present invention.

The amount of deflection of the deflected portion 2d of the strip material 2 supplied from the leveler 3 to the processing device 4 is detected by the detector 70' at a position slightly below the tension position 37 and having an appropriate amount of deflection. This detector 70 continuously converts the amount of deflection of the deflection portion 2d17) into an analog or digital electrical signal.

Referring to FIG. 6, the electric signal representing the amount of 1 glitch from the detector 70 is provided to a frequency conversion circuit 88a.

The frequency & gl conversion circuit 88a lowers the frequency of the derived di force as the amount of deflection detected by the detector 70 increases, and supplies power at a higher frequency as the amount of deflection decreases. As a result, the motor 21 of the leveler 3
As the rotational speed changes, it becomes possible to keep the amount of 4-biting of the bending portion 2d of the strip-shaped material 2 supplied from the leveler 3 to the processing device 4 constant. Therefore, the speed of the strip material FI2 supplied to the processing device 4 can be kept substantially constant, making it easy to improve productivity and quality at the same time.

The strip material 2 supported by the uncoiler 1 and wound is
Although it has a horizontal axis, the wound strip material 2 may of course be configured to be rotated by the motor 20 about an axis in the vertical direction and sent out.

The strip material 2 may be fed and pulled by conveying means other than rollers.

Effects As described above, according to the present invention, a deflection amount detection means is provided between the means for feeding out the strip-shaped material and the means for pulling the strip-shaped material, and the deflection amount of the strip-shaped material detected by the deflection amount detection means is The feeding speed of the feeding means is changed,
Therefore, the strip material can be fed at a constant rate, and the amount of deflection can be kept within an appropriate range. Therefore, the distance between the delivery means and the tensioning means can be shortened, and the strip-like material can be fed to the tensioning means in an appropriate orientation, for example in a substantially horizontal state. Therefore, the distance between the feeding means and the pulling means can be shortened, and the installation space in a factory or the like can be significantly reduced. In addition, the strip material is fed continuously, and the amount of deflection can be suppressed within an appropriate range even if the speed of the tensioning means changes slightly, so it is possible to improve productivity and prevent undesirable damage to the strip material. No tensile or compressive stress acts,
Quality can be improved. Further, since the strip material moves smoothly in the feeding means and the pulling means, its surface is not damaged.

Therefore, as mentioned in connection with the prior art, band-like (
In the present invention, it is not necessary to apply a protective layer to prevent the material from being scratched, and as a result, it is possible to improve the durability and reduce the cost.
