The strip takeup apparatus is characterized in that the apparatus comprises the following elements: a plurality of strip deflector devices, a plurality of take-up devices arranged downstream of the respective deflector devices along the direction of running of the strip, a strip guide device for making a wind-up angle at the leading vice.

20 Claims, 2 Drawing Figures PAIENTEnwuzswu sum 2 or z STRIP-TAKEUP APPARATUS This invention relates to a take-up apparatus, and more particularly to a take-up apparatus for taking up strips of thin plate material particularly as of steel web and the like in a rolling equipment and the like.

In a rolling equipment and the like, a take-up apparatus is installed for taking up a treated strip into a coil or roll.

In this type of take-up apparatus, atake-up supporting device such as a belt wrapper is provided which guides the strip to the take-up device and make it taken up thereby in the early stage of the take-up operation in order to facilitate and insure the take-up operation. Since in the conventional apparatus of this kind the take-up supporting device has been arranged at the rear portion of the take-up device and accordingly the take-up device and the take-up supporting device have been arranged along the direction of running of the strip, it has been disadvantageous in that not only the whole length of the apparatus becomes long but also there is a danger of bringing about human accidents or damaging the take-up supporting device by the edge of a cut strip when the strip is cut during the take-up operation. Further, it has been difficult to constantly carry out the maintenance and inspection of the take-up support device safely and securely, accordingly. On the other hand, in order to prevent the afore-mentioned accidents it is required to provide a protector which is disposed between the take-up device and the take-up supporting device while the take-up device is in operation.

In the case that this type of take-up apparatus is used in an equipment wherein a strip is continuously fed in such as the recent continuous rolling equipment, there are further troublesome problems as follows other than the above defects- In the continuous rolling equipment, several take-up machines are generally arranged along the direction of running of the strip and the continuously fed strip is taken up alternately by the several take-up machines. Since the several take-up machines employed in this type of rolling equipment are also accompanied by several take-up supporting devices respectively arranged in the direction of running of the strip, it is difiicult to arrange the takeup machines close to each other. Accordingly, in the conventional rolling equipment of this type, the take-up machines have been arranged at substantial intervals. It has been disadvantageous, accordingly, that the whole length of the apparatus becomes considerably long and it is very difficult to guide the strip between the take-up machines and it becomes further difficult to smoothly and automatically guide the strip therebetween as the running speed of the strip increases, and besides the output equipments requires an extra space due to the elongated pitch of the loaded coils on the output conveyor. In addition, since the take-up supporting device located on the take-up system side is disposed right under the running passage of the strip, the take-up supporting device is liable to be stained with oil dropping down from the strip and is likely to be brought into a trouble with cut pieces of strip falling thereinto. There have been various other defects in practical use such as difficulty had in maintenance and inspection of the take-up machines at the time such as of belt interchange.

The present invention eliminates the above described defects of the conventional take-up apparatus, and provides an apparatus which takes up a strip as of metal web into a coil by use of a take-up machine characterized in that a take-up supporting device such as a belt wrapper is arranged shiftable to the position under said take-up machine in the direction lateral to the running of the strip.

An object of the present invention is to provide a take-up apparatus which smoothly and securely takes up a strip of thin plate material such as steel web and the like.

Another object of the present invention is to provide a take-up apparatus suitable for preventing the damage of a take-up supporting device by improving the arrangement thereof.

Another object of the present invention is to provide a take-up apparatus which smoothly shifts a take-up supporting device thereby improving the work efficiency.

Still another object of the present invention is to provide a take-up apparatus which facilitates the feed out of the rolled up coils.

Still another object of the present invention is to provide a take-up apparatus wherein a take-up supporting device is movable in the direction right angle to the running direction of the strips.

A still similar object of the present invention is to provide a take-up apparatus wherein a take-up supporting device located right under the take-up machine is movable sideward, specifically right angle to the running direction of the strip.

A further object of the present invention is to provide a take-up apparatus advantageous for continuously takes up the continuously fed out strip and improves the operation efficiency thereof.

A further object of the present invention is to provide a take-up apparatus which has means suitable for guiding strips to a plurality of take-up devices.

A still further object of the present invention is to provide a take-up apparatus in which the arrangement of a deflector device is improved thereby making it possible to take up astrip even if the strip is continuously fed at a high speed from a single direction.

A still further object of the present invention is to provide a take-up apparatus which is made compact and the whole length thereof can be shortened.

A still further object of the present invention is to provide a take-up apparatus wherein the maintenance and inspection are facilitated and the safeness thereof is enhanced.

Other objects, features and advantages of the present invention will be made apparent from the following detailed description of the preferred embodiment thereof and the recitation in the appended claims taken inconjunction with the accompanying drawing in which;

FIG. 1 is a partial sectional view showing an embodiment of a take-up apparatus in accordance with the present invention, and

FIG. 2 is a partial sectional side view showing a part of the apparatus shown in FIG. 1.

The drawing shows an embodiment of the present invention wherein a strip is continuously taken up by use of two talc-up machines. Referring to FIGS. 1 and 2, take-up devices 11 and 12 are located at a level lower than a strip pass line and arranged along the running direction of the strip and take up the

strips

13 and 22 fed in through

deflector rollers

14 and 15 alternately on take-up drums 53 and 54.

Coils

51 and 52 wound up on the take-up drums 53 and 54 are transported on a coil transport truck 36. The coil transport trucks 36 are located right under the take-up devices 11 and 12 (Although only a coil transport truck 36 under the take-up device 12 is shown in FIG. 1, another coil transport truck of the same construction is located also under the take-up device 11.) and the respective trucks 36 are made movable on the rails 39 provided in the direction perpendicular to the running direction of the strip by means of wheels 38. Within a frame 34 provided on the respective coil transport truck 36 is slidably mounted a coil support column 49 and are provided an oil pressure cylinder 42 and an oil pressure piston 44 for moving up and down the coil support column 49.

Belt wrappers

16 and 17 are located right under the take-up devices 11 and 12 respectively and supported on belt

wrapper transport trucks

68 and 69 movable in the direction perpendicular to the running direction of the strip similarly to said coil transport trucks 36. The respective belt

wrapper transport trucks

68 and 69 are interconnected with said coil transport trucks 36 by way of pins 67, and the both

trucks

68 and 69, and 36 are made movable together in the direction perpendicular to the running direction of the strip by a partly illustrated driving device 61 through a fork end 63 and a pin 65. Further, the belt wrapper

transport trucks

68 and 69 have wheels 37 rolling on said rails 39 and are provided with belt

wrapper support columns

31 and 32 for supporting the

belt wrappers

16 and 17 respectively within frames 33 and 40 provided thereon and further provided with

oil pressure cylinders

41 and 48 for moving up and down the

support columns

31 and 32. In addition, said belt

wrapper support columns

31 and 32 are removably inserted into the frames 33 and 40 and not connected with the

oil pressure cylinders

41 and 48. Accordingly, the

belt wrappers

16 and 17 are wholly interchangeable.

The belt wrappers l6 and 17 are composed as well known ofa belt 19, a cylinder for extending the belt 21, a swingable arm 23, a cylinder 18 for swinging the swingable arm 23, rollers 24 to 30 and so forth. The

reference numerals

45 and 46 in the drawing designate pits having a capacity sufficiently retaining the

frames

33, 34 and 40 of the trucks, 55 indicates a base for supporting the take-up devices, and 59 indicates a space formed under the support base 55. A take-up drum 54 is driven by a take-up drum driving motor 57.

The state of the apparatus illustrated is that wherein the taking up of a strip 22 by the take-up device 12 has been completed and the cut strip is going to be taken up by the take-up device 11. The strip is guided as shown at the reference numeral 13. At this stage, the coil transport truck 36 on the side of the take-up device 12 is located right under the coil 52 as shown in FIG. 2, and the belt wrapper transport truck 69 is retained in the space 59 under the take-up device base 55. In order to move the coil 52 out of the line from this state, the oil pressure cylinder 42 is operated to place the coil 52 on the coil support column 49 and then the coil transport truck 36 is moved out of the line by the driving device 61. On the other hand on the side of the take-up device 11, the belt wrapper transport truck 68 is located right under the take-up drum 53, and prior to the start of the take-up operation the oil pressure cylinder 41 is operated as shown in P16. 1 to move the belt wrapper l6 upward and the belt 19 is made attached on the periphery of the take-up drum 53. Thereafter, the strip 13 is guided between the belt 19 and the take-up drum 53, and the strip 13 is taken up on the take-up drum 53 by means of the pressure of the belt 19 on the drum 53. After a desired amount of the strip has been taken up, the belt wrapper 16 and the belt wrapper support column 31 are moved downward and immediately thereafter the belt wrapper transport truck 68 is moved to set the belt wrapper aside out of the strip line so that the coil 52 may be transported out. Thus, by repeating the above operations alternately, the

strips

13 and 22 can be taken up alternately on the take-up devices 11 and 12 continuously. Further, in the case that the

belt wrappers

16 and 17 are required to be interchanged or repaired due to damages made on the belt or the like, the belt wrapper to be removed and some other devices accompanied thereby are first removed from the belt wrapper transport truck by means of a crane or the like outside the strip line, and then a preparatory belt wrapper and accompanied devices prepared in advance are mounted to the belt wrapper.

direction along the running direction of the strip. Be- 1 sides, the wasted time brought about the inconvenience of the take-up supporting device can be remarkably shortened.

Now the guide device of the strip will be described in detail referring to the drawing.

A frame 98 is provided above the take-up devices 11 and 12 so as to cover the

coils

51 and 52.

Deflector rollers

14 and 15 are provided on the frame 98. The vicinity of the

deflector rollers

14 and 15 serves as take-up inlets.

Strip guides

99 and 70 are provided between the take-up drums 53 and 54 respectively. The

strip guides

99 and 70 are pivotally mounted to

pivots

71 and 72 respectively so as to be rotated by means of cylinders 91 and 92.

Shafts

73 and 74 are disposed on a holder 75 provided on the frame 98 by way of

bearings

93 and 94.

Strip guiding members

76 and 77 are provided above said take-up inlet so as to be rotated about said

shafts

73 and 74 by means of

cylinders

78 and 79. The guiding

members

76 and 77 are able to be brought into contact with the

deflector rollers

14 and 15 with the intervention of

strips

13 and 22 respectively. A free roller 80 and a press rollers 81 are provided on said strip guiding member 76. An endless belt 83 is tensioned between said free roller 80 and press roller 81. This belt 83 is driven to rotate around the rollers at the same speed as that of the

strips

13 and 22. A free roller 84 and a press roller 85 are provided on said strip guiding member 17. An endless belt 88 is tensioned between the free roller 84 and the press roller 85. A strip guide 87 is mounted to a projected arm 88 of said strip guiding member 77. This guide 88 is slidable up and down along the sloped surface of a base 89 by means a cylinder 78. A guide 90 is mountedon said base 89. The reference numeral indicates a fixed guide and 96 shows a fork end.

Although an example of a guide device has a construction as described hereinabove, it will be understood that the present invention is not limited to this construction. Now the take-up operation of the strip in a continuous rolling equipment will be explained referring to FIG. 2. Thetake-up apparatus shown in FIG. 2

is in the state wherein the strip is being taken up by a take-up device 12. The

strip guiding members

76 and 77 are'pushed up to the upper limit by the

cylinders

78 and 79, and the

guides

87 and 90 are located on the pass line to guide the strip 22 which is being taken up in a coil 52 by the take-up device 12.

When the coil 52 reaches a predetermined amount, the continuously fed strip 22 is sheared and started to be taken up by the front take-up device 1 1. Prior to this shearing, the

strip guiding members

76 and 99 are brought into a preparatory state. First, the strip guiding member 76 are rotated about the shaft 73 by the cylinder 78, and the press roller 81 is put on the deflector roller 14 with the intervention of a belt 83. Besides, the strip guide 99 is rotated about the pivot 71 by the cylinder 91 and brought on a common tangential line of the take-up drum 53 and the deflector roller 14. At this stage, the strip is still on the take-up drum 54 and the strip is pinched between the deflector roller 14 and the belt 83 and rolled up in the coil 52 through the

guides

87 and 90 and the deflector roller 15.

Subsequent to the above operation, the strip is sheared. The strip is sheared by a flying shear (not shown) disposed ahead of the deflector roller 14, and divided into a leading end of a following strip and a trailing end of a preceding strip. The trailing end of the preceding strip is wound on the coil 52 under take-up operation, and the leading end of the following strip follows the trailing end of the preceding strip with little space therebetween and advances up to the take-up inlet. The leading end of the following strip is pinched be tween the belt 83 of the strip guiding member 76 and the deflector roller which have been prepared in advance as mentioned hereinbefore, and is suddenly bent downward to form a take-up angle at the end of the strip. Thus, the leading end of the following strip 13 is taken up on the take-up drum 53 through the guide 99.

At this stage, the following strip is wound on the drum 53 by several turns by the operation of the belt wrapper l6. Thereafter, the strip guiding member 76 is separated from the deflector roller 14, since a sufficient tension iscreated in the strip 13 by the take-up device 11.

Now, the opposite state of take-up operation to that hereinabove described, that is to say, the state wherein the take-up device 11 has completed the take-up operation and the strip is going to be switched to the other take-up device 12, will be explained. While the coil 51 is being taken up on the take-up drum 53, the strip guiding member 76 on the deflector 14 side is held in its upper position by the oil pressurecylinder 78. The guide 87 connected therewith through a projected arm 88 is also held in its upper limit so that the strip 13 running into the take-up drum 53 may not be obstructed thereby. These guides 87 and 90 are held in the lifted position and the strip guide member 77 is moved down by use of the cylinder 79 and the belt 86 is put into contact with the deflector roller 15, and the belt 86 and the deflector roller 15 are driven by the press roller 85 and become ready to receive the strip. Then the guide 70 is moved to the preparatory position. Thus, the right side take-up mechanism is set to guide the strip 22 to the take-up drum 54. If the strip is sheared with a flying shear under the above circumstances, the leading end of the strip advances straight without going toward the take-up drum 54 and reaches the deflector roller 15, and is guided to the take-up drum 54 by means of the strip guide member 77.

In accordance with the present invention, the strip as of metal web is guided so as to be easily taken up prior to its take-up, and in particular, the thin strip is well guided smoothly even if the leading end of the following strip comes close to the trailing end of the preceding strip, whereby a continuous take-up operation can be easily and securely performed, and further, the guide of the strip can be made smoothly and precisely since the leading end of the strip is guided with a takeup angle formed between the deflector roller and the press pollar by way of a belt.
