[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for concentrically aligning and arranging a large number of strips, for example, metal strips, and for simultaneously feeding the strips. The present invention relates to an improvement in a method and apparatus capable of feeding a large number of strips while maintaining tension.

[0002]

2. Description of the Prior Art One prior art multi-strip feeder comprises a number of uncoilers equal to the number of strips, with the strip coil to be fed on a feed roll of each uncoiler. However, this apparatus requires the same number of uncoilers as the number of strips, so that the equipment is large and the equipment cost is high.

Further, as shown in FIG. 9, another conventional multi-strip feeding device is rotatably supported on a common support shaft 126 via respective bearings 146, 146 ', 146 ". Strip coil 2, 2 ',
A number of rotating segments 130, 130 'carrying 2 "
130 ", and a number of these rotating segments 130, 130 ', 130" are brought into frictional contact with each other by a pressure adjusting mechanism 140 such as a hydraulic cylinder to form a number of strip coils. 2, 2 ', 2 "
(See, for example, Japanese Utility Model Laid-Open No. 63-48757). In the illustrated example, the pressure adjusting mechanism 140 includes a liquid cylinder 140A that directly presses the support shaft 126.
Is a web 130 "of the rotating segment 130" where the outer end flange 126a of the support shaft 126 is the outermost (left side in FIG. 8).
The support shaft 126 is urged rightward in FIG. 9 so that the web 130a of the innermost rotating segment 130 (the right side in FIG. 8) abuts against the fixed plate 150. Segments 130 and 130 ', 130' and 130 "
Are frictionally contacted to apply tension to the strip. This multi-strip feeding device has the advantages that a special drive source is not required, and that the equipment is reduced in size and the equipment cost is reduced.

However, the latter multi-strip feeding device can stably feed the strip when the feeding speed (running speed) of the strip is high. 13
Since the friction coefficient changes remarkably due to the roughness and deformation of the sliding surface between 0 ', 130' and 130 ", stable tension cannot be applied and instantaneous excessive tension is applied to the strip. There was a defect that the quality was deteriorated due to the application.

[0005]

One of the problems to be solved by the present invention is that a single feeding machine can simultaneously feed a plurality of strips, but the quality is always constant irrespective of the feeding speed. An object of the present invention is to provide a multi-strip feeding method capable of feeding a multi-strip simultaneously while maintaining the same.

A first object of the present invention is to provide a multi-strip feeding method for simultaneously feeding strips from a plurality of strip coils arranged concentrically and side by side. A plurality of strip coils supported by two common support shafts each having at least two sliding support members circumferentially spaced apart and engaged with the upper half of the inner peripheral surface of each strip coil of the plurality of strip coils It is an object of the present invention to provide a multi-strip feeding method characterized in that a strip is fed from each strip coil while applying different braking forces while rotating the coil on two sliding support members.

In the first means for solving the problems of the present invention, the braking force applied to the strip coil can be applied via the sliding support member.

A second object of the present invention is to provide a coil supporting means for rotatably supporting a plurality of strip coils which are concentrically aligned and arranged side by side, and a brake for applying a braking force to the strip coils. The coil supporting means includes at least two common support shafts penetrating through the hollow holes of the plurality of strip coils, and a plurality of strips respectively provided on the common support shafts. At least two sliding support members circumferentially spacedly engaged with the upper half of the inner peripheral surface of each strip coil of the coil, and the brake applying means separately applies the braking force to the strip coils. It is another object of the present invention to provide a multi-strip feeding device.

According to a second aspect of the present invention, the brake applying means comprises a brake shoe which is pressed against the sliding support member so as to apply a braking force to the strip coil via the sliding support member. Is preferred.

As described above, the plurality of strip coils are separately rotated via at least two sliding support members which are engaged with the upper half portion of the inner peripheral surface of each strip coil at intervals in the circumferential direction. If the brakes are supported and the strip coils are provided with separate brakes, the brakes can be braked in accordance with the feeding speed, as in the case of the prior art in which the coil supports supporting the strip coils slide frictionally with each other. The force does not fluctuate and does not degrade the strip.

In particular, it is preferable to apply a braking force via the sliding support member, because when the coil strip has a large weight, a predetermined tension can always be applied to the coil strip regardless of a change in the weight.

Further, since the plurality of strip coils are supported by at least two support shafts, when the strip is fed, the strip coil does not swing in the feeding direction and the strip is fed while maintaining a stable tension. be able to.

Next, the multi-strip feeding device 1 of the present invention.
Operation 0 will be described in detail with reference to the drawings together with the operation of the multi-strip processing equipment. As shown in FIG. 1, when a plurality of metal strips 1 are fed from the multi-strip feeding device 10 of the present invention, these metal strips 1
It is fed into the strip processing tank 12 via the feed roll 16. As this strip treatment, for example, there is a plating treatment of the metal strip 1, but other treatments may be used.
The metal strip 1 that has been subjected to the strip processing is wound by a multi-row winding device 14 via a take-up machine 18.

The multi-strip feeding device 10 of the present invention comprises:
Although it has two feeding parts 28A and 28B, in the state of illustration, as shown in Drawing 3 and Drawing 4, feeding part 28A is located in a pass line (line aligned with delivery roll 16 and strip processing tank 12), The feeding portion 28B is at the standby position (strip coil mounting position). Feeding unit 28 at standby position
Three strip coils 2, 2 ', 2 "are supported on sliding support members 46, 46' in the form of three sets of bearings of the coil support means 42 on B to prepare for the next feeding.
For the strip coils 2, 2 ', 2 ", the quick nut 74 and the backing member 72 shown in FIGS. 7 and 8 were removed, and then the coil holding cover 66 was removed, and the empty coil collars 3, 3', 3" were removed. Later, coil collars 3, 3 'with new strip coils 2, 2', 2 ",
3 "is supported on each sliding support member 46, 46 '.
As shown in FIG. 5, each strip coil 2, 2 ', 2 "
Coil collars 3, 3 ', 3 "are simply supported by their own weight on the two sliding supports 46, 46'.
The work of attaching the strip coils 2, 2 ', 2 "to the feeding portion 28B can be easily performed.

On the other hand, since each of the strip coils 2, 2 ', 2 "on the feeding section 28A is on the pass line and is taken by the take-up machine 18 through the feed roll 16 and the strip processing tank 12, this strip coil 2 It is sequentially fed out according to the take-up of the take-up machine 18. At this time, the three strip coils 2,
2 ', 2 "are supported by a common support shaft 26, 26', but since they are to be arranged independently of each other, these strip coils 2, 2 ', 2" interfere with each other. Therefore, even if the metal strips 1 to be fed have different thicknesses and the feeding rotation speeds of the strip coils are different, the strips 1 can be fed without any trouble without frictional sliding.

Each strip coil 2, 2 ', 2 "
Are supported by the two support shafts 26, 26 ', so that these strip coils 2, 2', 2 "do not swing in the running direction (the direction along the pass line),
These strip coils 2, 2 ', 2 "
6, 26 'stably supported. This prevents fluctuations in tension due to coil run-out during the feeding of the strips 2, 2 ', 2 ", and enables the strips 2, 2', 2" to be fed stably. In addition, although not shown, it is preferable to sandwich a slippery protective plate made of resin or the like between the adjacent strip coils 2 and 2 ′ and between the strip coils 2 ′ and 2 ″. It has a function of preventing the end faces of the adjacent strip coils from being in frictional contact with each other and being damaged, but additionally, the strip coils 2, 2 ', 2 "also fall down in the axial direction of the support shafts 26, 26'. It also has the function of preventing

The own weight of the strip coils 2, 2 ', 2 "including the coil collars 3, 3', 3" is increased by 250 according to the feeding.
and that the fluid cylinders 58, 58 ', 58 "of the brake application means 44 apply a constant load of 20 kg to the brake shoes 56, 56', 56". The friction coefficient μ of the sliding surface a between the sliding support member 46 and the sliding shoes 56, 56 ′, and 56 ″ is 0.2. Assuming that the friction coefficient μ of the sliding surface b is 0.4, the friction force Fa of the friction surface a is 5 kg in its own weight.
Is 0.2 × 5 = 1 kg, and its own weight is 250 kg, and 0.2 × 250 = 50 kg.

The frictional forces Fa and Fb between the sliding surfaces a and b are balanced when the weight of the strip coils 2, 2 ', 2 "including the coil collars 3, 3', 3" is 40 kg. Therefore, when the weight of the strip coils 2, 2 ', 2 "is from 250 kg to 40 kg, the metal strip 1 is braked while sliding on the sliding surface b, and the strip coils 2, 2', 2" When its own weight is 40 kg to 5 kg, the metal strip 1
Brake on

When all of the strip coils 2, 2 ', 2 "on the payout section 28A on the pass line are paid out, the coupling 34 of the turning mechanism 22 is connected, the rotary actuator 30 is driven, and the turning shaft 36 is turned 180. , The feeding portion 28A becomes the standby position, and the feeding portion 28A
B is located on the pass line. Therefore, this time, the metal strip strip 1 is fed out from the feeding section 28B to perform the strip processing, while the feeding section 28A at the standby position supports the new strip coils 2, 2 ', 2 "to prepare for the next feeding. When the feeding portions 28A and 28B come to predetermined positions, a locking means (not shown) of the turning mechanism 22 locks them and maintains the positions.

When the strip coil is supported by the feeding portion 28A or 28B at the standby position, it is, of course, necessary to make the feeding direction constant when the strip coil is moved to the pass line by the turning mechanism 22. It is. This is the same regardless of whether the turning mechanism 22 turns the turning shaft 36 in one direction or reversibly.

In the above-described embodiment, the brake applying means 44 is provided with the brake shoe 5 on one of the sliding support members 46.
6, 56 ', 56 "are engaged, but a brake shoe may be engaged with both sliding support members 46, 46'.
Further, the brake applying means may engage the brake shoe with the inner peripheral surface of the lower half of the coil collar 3, 3 ', 3 "instead of the sliding support member. In this case, the strip coil 2, 2' In order to prevent the braking force from becoming too strong at the appropriate time when the self-weight is reduced due to the advance of 2 ",
It is preferable to reduce or eliminate the pressing force of the brake shoe.

Further, in the above-described embodiment, the left and right feeding portions 28A and 28B are provided, and the position is alternately switched between the pass line and the standby position by the turning mechanism 22.
Only one feeding portion may be provided, and in this case, the turning mechanism 22 is not necessarily required. Further, the number of the sliding support members of the feeding portion can be appropriately selected as needed.

[0037]

According to the present invention, as described above, at least two sliding support members which are engaged with the upper half of the inner peripheral surface of each strip coil of the plurality of strip coils at intervals in the circumferential direction are provided. Each strip coil is supported so as to rotate separately, and a separate brake is applied to the strip coil, so that adjacent strip coil supports slide frictionally with each other as in the related art. In addition, the braking force does not fluctuate according to the feeding speed, and the quality of the strip does not deteriorate.

In particular, when a braking force is applied via the sliding support member, when the strip coil has a large weight, tension is applied to the strip while causing a slip with a smaller frictional force in accordance with a change in the weight. This is preferable because a substantially stable tension can be applied to the strip.

Further, since the plurality of strip coils are supported by at least two support shafts, the strip strip can be stably fed without swinging in the feeding direction at the time of feeding.

Further, since a plurality of strip coils are supported by a common support shaft, the equipment cost is lower than in the case of feeding from a separate feeder. However, these strip coils are provided in the hollow portion thereof. Since the support shaft is supported so as to penetrate loosely, the operation of supporting the strip coil in the device can be easily performed.
