Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a process equipment (line) for continuously processing strip-shaped plate materials (strips) such as rolled steel strips, which is a line which should not be stopped such as plating equipment. The present invention relates to a looper (strip storage facility) arranged on the entry / exit side.

2. Description of the Related Art Generally, a vertical type looper has hitherto been lifted and lowered by hoisting four corners of a carriage for lifting and lowering with a chain or the like. The guide also had its four corners functioning as guides by means of wheels, etc., but the gap was large, and the amount of expansion was different due to load fluctuations when driving the chain at four locations and during lifting, so the entire carriage tilted in all directions. Often.

The plate passing state depends on the fluctuation of the horizontalness of the roll. Therefore, the plate passing often causes a meandering to the plate passing.

[0004]

A means for solving the problems will be described with reference to the drawings. Vertical guide columns 10 and 11 are provided upright at the centers of the front entrance side 51 and the rear exit side 52 of the looper 50, respectively, and a moving body 12 that moves vertically along the guide pillars 10 and 11,
13, the bracket 14, which is provided at the center of the front and rear of the carriage 54 in which the horizontal horizontal upper rolls 53 are arranged,
15 and the center of the horizontal transverse balance bars 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 columns 2a, 2b, 2c and 2d. Carriage up / down chains 3a, 3b, 3
c and 3d are connected to the left and right ends of the balance bars 16 and 17, respectively.

[0005]

Embodiment 55 is a base frame of the looper 50 and has a rectangular parallelepiped shape. Reference numeral 51 is a front side entrance side of the looper, and 52 is a rear side exit side of the looper. 3a, 3b, 3c, and 3d are carriage up-and-down chains arranged along the four corners of the base frame 55. The upper chain cars 4a, 4b, 4c, 4d and the lower chain cars 5a, 5b, 5c,
It is stretched between 5d.

The left and right lower chain wheels 5a and 5b on the entrance side and the left and right lower chain wheels 5c and 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 are adapted to rotate together at the same speed.

Numerals 10 and 11 are vertical guide columns standing upright at the center of the front and rear faces of the base frame 55, and 12 and 13 are guide columns 1.
It is a moving body which moves up and down along 0 and 11, and guides the guide pillars 10 and 1 through the trochanters 24 and 25 so as to move lightly and smoothly.
It is attached to 1.

Reference numerals 16 and 17 denote horizontal balance bars whose center is pivotally supported by front and rear horizontal pivots 18 and 19 of the moving bodies 12 and 13, and the left and right ends of the balance bars 16 and 17 are the carriage vertical chains 3a, 3b, 3c, respectively. It is attached to 3d.

Reference numeral 54 denotes a rectangular carriage which is arranged below the balance rods 16 and 17, and which has columns 4a at four corners of a base frame 55.
It moves up and down in 2b, 2c and 2d. Brackets 14 and 1 provided at the centers of the front and rear ends of the carriage 54
5 is pivotally attached to the horizontal pivots 18, 19. A large number of horizontal horizontal rolls 53 are attached to the carriage 54, and a plurality 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 coming in from the upper entrance side passes through the upper and lower rolls 53 and 59 and the steering roll 60 alternately so as to go out from the upper exit side 52.

When there is a speed difference between the passing plates 61 on the inlet side 51 and the outlet side 52, the motor 56 rotates in accordance with the speed difference to displace the carriage 54 up and down, and the upper roll 5 moves.
The length of the threaded plate 61 between the 3 and the lower roll 59 is changed to correspond to the speed difference between the threaded plate 61 on the inlet side and the outlet side.

Left and right chains 3a, 3b or 3c, 3d
When the left and right vertical relative positions of the balance rods 16 and 17 are different due to the dimensional difference between the chain rings of the balance rods 16 and 17,
Is inclined, but the carriage 54 has a central horizontal pivot 18,
Since it is suspended from the support 19, it is possible to cope with the movement of the passing plate 61 without causing an inclination in the left-right direction.

[0013]

In order to maintain the horizontality of the carriage loading roll, a pair of guide columns 10 and 11 having a gap as small as possible are provided to prevent the carriage from tilting. Therefore, when the carriage is moved up and down, the clearance is small, and there is no play, so that the carriage moves up and down smoothly, and the proximity switch or the like can be easily attached, and the detection position becomes highly accurate and precise operation becomes possible.

A pair of balance rods are installed to absorb the chain elongation at four places caused by holding the carriage horizontally, and the carriage is not inclined by connecting the chains to the balance rods, but only the balance rods are inclined. It was decided to hold the horizontal position up and down. Therefore, since the roll is held horizontally, the condition of the plate material at the time of passing the plate is improved, which is effective in preventing meandering. In addition, a steering roll is usually installed to correct the number of threaded strips, but this is not necessary. Further, the tilting of the balance bar does not exert a twisting force for ascending and descending up to the carriage, so the mechanical role of the protective device is sufficiently effective.
