Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traverser material holding device for stably holding a stack material conveyed by a traverser.

[0002]

2. Description of the Related Art For example, when a rolled rod-shaped steel material is bundled and conveyed to the next heat treatment step, it is conveyed by a traverser 1 as shown in FIGS. Traverser 1
Has a plurality of traverser arms 3 vertically erected on the lower surface of the frame 2 along the longitudinal direction at predetermined intervals. Each traverser arm 3 has an upper end of each of two arms 4 and 4 forming an inverted L shape. It is rotatably supported on the frame 2 by the shaft 5,
The lower end side can be opened and closed to the left and right. The traverser 1 moves while holding the bar-shaped steel material 6 held at a plurality of positions by each traverser arm 3 and conveys it to the next process.

By the way, in the case of transporting the flat bar from the rolling process to the heat treatment process by the traverser, the flat bar carried out from the rolling process is stacked and then transported to the bundling position by the traverser (hereinafter referred to as "flat bar"). Stacked materials) are bundled, and after binding, they are conveyed to the heat treatment step. This is to prevent twisting and bending of the flat rectangular material conveyed in the heat treatment step.

[0004]

However, since the above-mentioned conventional traverser is configured to simply hold the steel material and carry it, when carrying the stacked flat rectangular material, it shakes and collapses during the transportation, or When bundling, the load collapses,
Even if they are stacked in layers, it will be the same as if they were stacked in bulk. For this reason, there is a problem that the flat bar is twisted or bent during storage until it is bundled and then transferred to the heat treatment step, which requires correction and reheat treatment, which leads to a lead time in the heat treatment step. is there.

The present invention has been made in view of the above points, and an object of the present invention is to provide a material holding device for a traverser that prevents collapse of stacked materials during transportation and binding of the traverser.

[0006]

In order to achieve the above object, according to the present invention, a traverser frame for carrying a stacked material is carried by a plurality of traverser arms provided at intervals in the longitudinal direction of the frame. A structure that includes a vertically extending pantograph mechanism that is vertically expandable and contractible, and a presser mechanism that is provided at the lower end of the pantograph mechanism so as to be openable and closable in the left and right direction and that holds the stack material held by the traverser arm. is there.

In the material pressing device, after the traverser holds and holds the stack material by the traverser arm, the pantograph mechanism is extended to lower the holding mechanism, and the holding mechanism holds the stack material from above and from both sides.
As a result, the collapse of the stack material held by the traverser arm during transportation and binding of the traverser is prevented.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below based on Examples. The same members as those shown in FIG. 4 are designated by the same reference numerals and the description thereof will be omitted. Due to the structure of the traverser, it is not possible to secure sufficient space at the top or both sides. Therefore, in the present invention, a narrow space is effectively used by arranging a material pressing device that presses the material held by the traverser arm below the frame of the traverser. In FIG. 1, a traverser 1 is provided with a material pressing device 10 vertically provided on a lower surface of a frame 2 in the vicinity of appropriate traverser arms 3 on one side and in the middle. The material pressing device 10 includes a pantograph mechanism 11 and
The holding mechanism 12 is connected to the pantograph mechanism 11 and holds the stacked material 40 that is stacked and held on the traverser arm 3 and presses the upper surface and upper parts of both side surfaces.

As shown in FIGS. 2 and 3, the pantograph mechanism 11 is composed of a pantograph 14 which expands and contracts in the vertical direction, and a drive section 15 which drives the pantograph 14 to expand and contract. The drive unit 15 includes a frame 16 laterally fixed to the lower surface of the frame 2 and a hydraulic cylinder 1 disposed on one side of the lower surface of the frame 16 along the longitudinal direction.
7 and a slider 19 slidably mounted on a slide guide 18 provided on the lower surface of the frame 16 from the center to the other side along the longitudinal direction. The cylinder 17 is fixed to a bracket 20 that is fixed to one side of the lower surface of the frame 16, and the tip of the rod is the slider 1.
9.

The pantograph 14 is a pantograph 14a.
And 14b are connected in two stages, and the pantograph 14a is formed by arranging the links 21 and 22 in an X shape and pivotally supporting the center portion so that the pantograph 14b can be formed similarly. The links 23 and 24 are arranged in an X shape and are pivotally supported in the central portion so as to be rotatable. The lower ends of the links 21 and 22 of the pantograph 14a and the upper ends of the links 23 and 24 of the pantograph 14b are rotatably connected to each other.

In the pantograph 14, when the free ends of the links 21 and 22 are opened, the free ends of the links 23 and 24 are opened and shrunk accordingly, and conversely, when the free ends of the links 21 and 22 are closed, the free ends of the links 21 and 22 are correspondingly closed. The free ends of the links 23, 24 are closed and extend. In this way, the multi-stage (2-stage) pantograph 1
4 are configured. In the pantograph 14, the upper ends of the links 21 and 22 are rotatably supported by the slider 19 and the bracket 20 and are suspended.

The holding mechanism 12 includes a frame 25, a hydraulic cylinder 26 arranged along one of the longitudinal sides of the frame 25 from the approximate center of the upper surface thereof, and a longitudinal direction of the upper surface of the frame 25 extending from the approximate center to the other side thereof. A slider 28 slidably mounted on a slide guide 27 provided along the sprocket 2 rotatably supported at both ends of the frame 25.
9 and 30, a chain 31 hung around these sprockets 29 and 30, and pressing plates 33 and 34 slidably mounted on a slide guide 32 provided on the lower surface of the frame 25 along the longitudinal direction. It is configured.

The cylinder 26 is fixed to a bracket 35 fixed to the other end of the upper surface of the frame 25. The tip of the rod of the cylinder 26 is fixed to a predetermined portion of the chain 31 via a bracket 36, for example, near the center on the upper side in the figure in a shortened state. Also, the holding plate 33,
Each of the upper portions 34 is a holding plate 33 in a state where the upper portion of the chain 31 is in a predetermined position, that is, the rod of the cylinder 26 is shortened.
The upper part of the sprocket 3 is located below the chain 31 near the sprocket 29, and the upper part of the holding plate 34 is located below the sprocket 3
It is fixed to the chain 31 located on the upper side near 0. Then, the upper ends of the slider 28 and the bracket 35 are
Each of the links 23 and 24 of the pantograph link 14 is rotatably connected to and suspended from the lower ends of the links 23 and 24.

The operation will be described below. In FIG. 3, the material pressing device 10 includes a driving unit 15 of a pantograph mechanism 11.
When the cylinder 17 is shortened, the slider 19 is moved to the right in the figure, and the pantograph 14 is extended accordingly to lower the holding mechanism 12 to the lower limit position. When the cylinder 17 is extended, the pantograph 14 is shortened accordingly. Then, the presser mechanism 12 is raised. Then, when the cylinder 17 extends to the maximum position shown by the chain double-dashed line, the slider 19 moves to the position 2 in the figure.
It moves to the left to the position indicated by the dashed line, and the holding mechanism 12 is lifted to the upper limit position indicated by the dashed line 2.

Further, the material pressing device 10 includes a pressing mechanism 12
When the cylinder 26 of the
4 is moved to the left and right to the maximum position as shown by the solid line and is open. As the cylinder 26 extends, the lower side of the chain 31 moves to the right side in the figure and the upper side moves to the left side, and the presser plates 33, 34 are moved.
Moves toward the center. And the cylinder 26
When extended to the maximum position indicated by the dotted line, the holding plates 33, 3
4 moves to the position indicated by the chain double-dashed line.

In the material pressing device 10, when the pantograph 14 extends to the maximum length, the pressing mechanism 12 descends to the vicinity of the lower end of the traverser arm 3 (FIG. 2), and when the cylinder 26 shortens to the maximum position, the pressing plate is pressed. The distance between 33 and 34 expands to the width of the material holding area at the lower end of the traverser arm 12. When the material pressing device 10 is used, the holding plates 33 and 34 of the pressing mechanism 12 are lowered to a position where they can sufficiently press the stack material held by the traverser arm 3, and when the material pressing device 10 is not used, the pressing mechanism 12 of FIG. The expansion / contraction length of the pantograph 14 and the pressing plates 33, 3 are adjusted so that the pressing plates 33, 34 do not interfere with the material held by the traverser arm 3 by being raised to the position indicated by the chain double-dashed line.
The size of 4 is set.

Next, the rectangular members 6 stacked by the traverser
The case of transporting paper will be described. Material holding device 10
Indicates that the presser mechanism 12 is at the upper limit position shown by the chain double-dashed line in FIG. 3, and the presser plates 33 and 34 are in the state of being opened to the maximum width. Then, the rectangular members 6 to be conveyed are assumed to be stacked members 40, for example, placed on a sleeper (not shown) in two rows and eight steps. The stacked material 40 is held by the traverser arm 3 as shown in FIG. Next, the material pressing device 1
The pantograph 14 of 0 is extended to lower the pressing mechanism 12, and the lower surface of the frame 25 is brought into contact with the upper surface of the stack material 40.

Next, the cylinder 26 of the holding mechanism 12 is extended to move the left and right holding plates 33, 34 toward the center, and abut on the upper portions of both side surfaces of the stack 40. As a result, the stacked material 40 is held by being held by the traverser arm 3 as shown in FIG.

After the stack material 40 has been taken in by the traverser arm 3 in this way, the traverser 1 is raised, fed laterally to the bundling position and stopped there, and the stacking device 40 is held while holding the stack material 40 as shown in FIG. It binds with (not shown). Since the stacked material 40 is held by the material pressing device 10 while being held in the traverser arm 3, the stacked materials 40 are prevented from collapsing at the time of transportation and at the time of binding. The material holding device 10 holds the holding plate 3 after the stacking of the stacked materials 40 is completed.
Pantograph 1 while separating 3, 34 from both sides
4 is shortened and the presser mechanism 12 is raised.

After the stacking materials 40 have been bound, the traverser 1 rises again while holding the stacking materials 40 and conveys them to the next heat treatment step, and places the stacking materials 40 on the cradle. Since the stacked material 40 is bound in an orderly stacked state and placed on the cradle, twisting, bending, etc. are prevented from occurring during storage before being transported to the next heat treatment step. In addition, in the said Example, although the case where the flat rectangular material was piled up as a stacking material was described, it is not restricted to this and it is the same also in the case of a mountain-shaped material.

[0021]

As described above, according to the present invention, it is possible to prevent the stacked materials from collapsing when the stacked materials are conveyed and bound by the traverser, and the stacked materials are bound in the stacked state. Therefore, the generation of twisting or bending of the material during storage can be prevented. As a result, it is possible to favorably perform the heat treatment of the flat bar or the like that has been rolled and then conveyed to the next heat treatment step, and the work efficiency can be improved.
