DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process equipment (line) for continuously processing a strip material (strip) such as a rolled steel strip, particularly a line which must not be stopped such as a plating equipment. The present invention relates to a looper (strip storage facility) arranged on the entrance side.

[0002]

2. Description of the Related Art Up to now, a vertical looper generally lifts and lowers four corners of a lifting / lowering unit carriage by means of a chain or the like and individually drives them. The guides also functioned as guides at the four corners with wheels, etc., but the clearance was large, and the amount of elongation differed individually due to load fluctuations during driving of the four chains and during lifting, so the entire carriage tilts in all directions. Often.

[0003] The passing state of the plate material depends on the fluctuation of the horizontality of the roll, and for this reason, the passing of the plate material is often meandered and hinders the passing.

[0004]

The present invention will be described with reference to the drawings. Vertical guide pillars 10 and 11 are erected at the center of the front entrance side 51 and the rear exit side 52 of the looper 50, respectively, and the moving body 12, which moves vertically along the guide pillars 10 and 11, respectively.
13, a bracket 14, which is provided at the front and rear center of a carriage 54 in which horizontal and horizontal upper rolls 53 are arranged.
15 and the center of the horizontal horizontal balance rods 16 and 17 are respectively supported on the front and rear horizontal pivots 18 and 19 of the front and rear moving bodies 12 and 13, respectively, and provided along the four corner columns 2a, 2b, 2c and 2d. Carriage vertical chains 3a, 3b, 3
c and 3d are connected to the left and right ends of the balance rods 16 and 17, respectively.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 55 denotes a base frame of a looper 50 having a rectangular parallelepiped shape. 51 is a front entrance side of the looper, and 52 is a rear exit side of the looper. Reference numerals 3a, 3b, 3c, and 3d denote carriage vertical chains arranged along the four corners of the base frame 55. The upper and lower sprockets 4a, 4b, 4c, and 4d and the lower sprockets 5a, 5b, 5c,
5d.

The left and right lower sprockets 5a, 5b on the entry side and the left and right lower sprockets 5c, 5d on the exit side are fixed to the front shaft 20 and the rear shaft 21, respectively. , The motor 56, the speed reducer 57, the main shaft 58, the front endless chain 22, and the rear endless chain 23, so that they can be linked and rotated at the same speed.

[0007] Reference numerals 10 and 11 denote vertical guide columns erected at the center of the front and rear surfaces of the base frame 55, respectively.
It is a moving body that moves up and down along 0 and 11 and guides pillars 10 and 1 via trochanters 24 and 25 to move lightly and smoothly.
It is attached to 1.

Reference numerals 16 and 17 denote horizontal balance rods pivotally supported at the center on front and rear horizontal pivots 18 and 19 of the movable bodies 12 and 13, respectively. Left and right ends of the balance rods 16 and 17 have the carriage vertical chains 3a, 3b, 3c and 3c, respectively. It is bound to 3d.

Reference numeral 54 denotes a rectangular carriage disposed below the balance rods 16 and 17, and supports 4a at the four corners of the base frame 55.
It moves up and down in 2b, 2c and 2d. Brackets 14, 1 provided at the center of each of the front and rear ends of the carriage 54
5 is pivotally mounted on the horizontal pivots 18,19. A number of horizontal horizontal upper rolls 53 are attached to the carriage 54, and a number of horizontal horizontal lower rolls 59 and a steering roll 60 provided as necessary are provided below the base frame 55.
Is provided.

[0010]

The passing plate 61 that has entered from the upper entry side passes through the upper and lower rolls 53 and 59 and the steering roll 60 alternately in a sewing manner and exits from the upper exit side 52.

When a speed difference occurs between the passing plate 61 on the inlet side 51 and the outlet side 52, the motor 56 rotates in accordance with the speed difference, and displaces the carriage 54 up and down.
The length of the passing plate 61 between 3 and the lower roll 59 is changed to correspond to the speed difference of the passing plate 61 between the entrance side and the exit side.

Left and right chains 3a, 3b or 3c, 3d
When there is a difference between the left and right relative positions of the balance rods 16 and 17 due to the dimensional difference between the chain rings of
Is inclined, but the carriage 54 is positioned at the central horizontal pivot 18,
Since it is in a state of being suspended and supported by 19, it is possible to cope with the movement of the passing plate 61 without inclining in the left-right direction.

[0013]

According to the present invention, a pair of guide columns 10 and 11 having a minimum gap is installed to maintain the horizontal level of the carriage loading roll, thereby preventing the carriage from tilting. For this reason, when the carriage is moved up and down, there is little gap, so that there is no play, and the carriage can be moved up and down smoothly, and the proximity switch and the like can be easily attached, the detection position becomes highly accurate, and precise operation becomes possible.

[0014] A pair of balance rods are installed to absorb the elongation of the chain at four places caused by holding the carriage horizontally, and the carriage is not inclined by connecting the chain to the pair of balance rods. It was decided to keep the horizontal position up and down. For this reason, since the roll is held horizontally, the state of the plate material at the time of passing is improved, which is effective in preventing meandering. In addition, when the number of threading members is large, a steering roll for correcting the number is usually installed, but this is not required. Further, since the twisting force of the lifting and lowering does not act on the carriage due to the inclination of the balance bar, the role of the protection device is mechanically sufficiently effective.
