Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a stop device for turning rolls.

[Conventional technology]

In the conventional turning roll, a rotating body is supported by a driving turning roll on a driving base and a driven turning roll on a driven base, and the rotating body is rotated by the drive of the driving turning roll. The body undergoes welding, cutting, painting, inspection, cleaning, etc.

[The problem that the idea attempts to solve]

When the rotating body moves in the axial direction, there are problems such as machining not being done at the desired position of the rotating body and damaging the rotating body,
There was also a problem that accidents such as the rotating body falling from the turning roll, which continues to rotate, occurred.

The axial movement of the rotating body mentioned above is caused by the fact that the axis of the rotating body is not horizontal, but even if the axis of the rotating body is horizontal, the drive turning on which the rotating body is mounted It can also be caused by a lack of equilibrium between the roll and the driven turning roll. In addition, even if both turning rolls are balanced and the axes of the rotating body are parallel, problems such as welding on the rotating body, scratches on the rotating body, processing accuracy of the rotating body, etc. may cause the rotating body to become perfectly round. The shape of the rotating body also causes axial movement. Therefore, it is impossible to move the rotating body in the axial direction.

Therefore, the object of this invention is to provide a walking stop device in which the alignment of the rotating body is automatically aligned.

[Means to solve the problem]

In order to achieve the above object, this invention provides a turning roll consisting of a driving stand provided with a pair of driving turning rolls rotationally driven by a motor, and a driven stand provided with a pair of driven turning rolls. , a lower frame installed on the floor, etc., an upper frame bearing a pair of drive turning rolls rotatably driven on the upper surface and placed above the lower frame, and located at the center of the facing surface between the upper frame and the lower frame. a fixed member fixed to either one of the upper frame and the lower frame, a rotating member rotatably attached to the other via a vertical rotation axis, and both ends of the fixed member and the rotating member facing each other A drive stand is constructed by a gutter-like recess and a semi-cylindrical protrusion that are fitted so that the connecting line intersects at right angles to the axis of the drive turning roll, and an elastic member interposed between the upper frame and the lower frame. It also consists of a lower frame installed on the floor etc., an upper frame bearing a pair of driven turning rolls on its upper surface and placed above the lower frame, and located at the center of the facing surface between the upper frame and the lower frame. and a fixed member fixed to either the upper frame or the lower frame, a rotating member rotatably attached to the other via a vertical rotation axis, and both ends tied to opposing surfaces of the fixed member and the rotating member. A driven table is composed of a gutter-like recess and a semi-cylindrical protrusion that are fitted so that the lines intersect at right angles to the axis of the driven roll, and an elastic member interposed between the upper frame and the lower frame. This is what I did.

[Effect]

The lower part of the outer periphery of both ends of the rotating body is supported by the driving turning roll of the driving base and the driven turning roll of the driven base, and the rotating body is rotated by the drive of the driving turning roll.

Both upper frames having the driving turning roll and the driven turning roll of the driven table perform rotational movement by the rotating shaft and rocking movement by the concave portion and the convex portion, so that the center of rotation of the rotating body is automatically aligned. Prevents the rotating body from moving.

〔Example〕

As shown in FIGS. 1 and 2, a rotating body 3 such as a cylinder or a circular object is placed on a driving table 1 and a driven table 2, which are installed parallel to the floor or the like at a predetermined interval. Ru.

A rotating member 8' is rotatably mounted via a vertical rotating shaft 7, and a line connecting both ends of the fixed member 9' and the rotating member 8' to opposing surfaces intersects at right angles to the axis of the driving turning roll. It is composed of a trough-like recess 8 and a semi-cylindrical protrusion 9 which are fitted together so as to fit together, and an elastic member 10 interposed between the upper frame 6 and the lower frame 4.

The driven table 2 also includes a lower frame 11 installed on the floor or the like, and a pair of driven turning rolls 12, 12 supported on the upper surface of the lower frame 11.
An upper frame 13 disposed above, and an upper frame 13 and a lower frame 1 located at the center of the opposing surfaces of the upper frame 13 and lower frame 11.
A fixing member 16' fixed to either one of the parts 1 and a rotating member 15' rotatably attached to the other via the vertical rotating shaft 14, and both ends on opposing surfaces of the fixing member 16' and the rotating member 15'. The upper frame 13 and the lower frame 11 are interposed between a gutter-shaped recess 15 and a semicircular protrusion 16, which are fitted so that the line connecting them intersects at right angles to the axis of the driven turning roll 12. It is composed of an elastic member 17.

In the illustrated case, the rotating shafts 7 and 14 are supported on the lower frames 4 and 11, but the upper frames 6 and
13.

In addition, in the illustrated case, recesses 8, 15 are provided on the rotating members 8', 15', and protrusions 9, 16 are provided on the fixed members 9', 16'.
is provided, but it may be provided in reverse.

Furthermore, although the elastic members 10 and 17 are shown as coil springs arranged at both ends of the upper frames 6 and 13 in the swinging direction, they may be made of rubber or the like.

The drive turning rolls 5, 5 are driven by a shaft 19 driven by a motor 18, and a worm wheel fixed to the end of the drive turning rolls 5, 5 so as to mesh with a worm gear 20 of this shaft 19. 21, motor 1
8, the shaft 19 is driven to transmit rotation in the same direction from the worm gear 20 to the worm wheel 21 to the driving turning rolls 5, 5, but it may be driven by other methods. .

22 is a stop device that stops the upper frames 6, 13 from turning beyond a required range.

The above-mentioned stop device 22 has a long hole 24 provided in the seat plate 23 of the upper frame 6, 13 in the case shown in the figure.
It consists of a screw shaft 25 that is erected from the lower frames 4, 11 so that its upper part passes through the elongated hole 24. Reference numeral 26 denotes a protrusion that prevents the protrusions 9 and 16 from sliding laterally.

The turning roll according to this invention has the above configuration, and its operation will be explained next.

The driving turning rolls 5, 5 of the driving table 1 and the driven turning rolls 12, 12 of the driven table 2 support the lower part of the outer periphery of both ends of the rotating body 3, and when the driving turning rolls 5, 5 are driven, the rotating body 3
rotates.

At this time, the driven turning rolls 12, 12
is rotating due to contact with the rotating body 3.

It also includes an upper frame 6 with driving turning rolls 5, 5 and driven turning rolls 12, 1.
The upper part 13 having the rotor 2 performs a turning motion by the rotating shafts 7 and 14 and a swinging motion by the fitted recesses 8 and 15 and convex parts 9 and 16, so that the axis of the rotary body 3 is automatically aligned. , prevents the rotating body 3 from moving in the axial direction.

〔effect〕

As described above, according to the stopping device for a turning roll according to this invention, the rotational movement of the upper frame by the rotating shaft and the swinging movement of the upper frame by the fitted sliding bearing between the concave part and the convex part Since the alignment center is automatically aligned, it is possible to prevent the rotating body from moving forward.

Therefore, it is possible to eliminate the problem of misalignment during various operations due to the movement of the rotating body.
