Description

[Detailed Description of the Invention] [Industrial field of application] The present invention may be used for centering a load on a loading table by mounting it on a loading table for loading a load transported by a forklift or the like. The present invention relates to a centering device which is mounted on a lifting tool such as a crane and used for centering a load hung by the lifting tool.

[Prior Art] When a load transported by a forklift or the like is placed on a stand and then handled by another automatic machine or the like, the load transported by the forklift or the like is accurately placed on the stand. It is required from the standpoint of workability that it is centered on and placed on. However, it is difficult to accurately center and lower the load to a predetermined position on the table by operating the forklift, and it takes time to operate and center the forklift. It is inferior and inefficient. Therefore, in order to enable centering of luggage that is roughly placed on the stand, even if the luggage that has been conventionally transported by a forklift is placed roughly on the stand, the luggage will be automatically centered. A table having a centering device that can be placed at a predetermined position has been developed.

The table provided with the conventional centering device is shown in FIGS.
As shown in the figure, a fixed frame 3 in which four columns 1 arranged at four corners of a rectangle are firmly connected and supported by a connecting member 2.
And a movable frame 6 having four legs 5 at four corners of a rectangular underframe 4 having an outer diameter larger than that of the fixed frame 3 in plan view. It is located above the fixed frame 3 in a floating state, and is provided between the columns 1 of the fixed frame 3 and the legs 5 of the movable frame 6 so as to project outward at the upper ends of the columns 1. An upper plate 7 as a fixed member, and a lower plate 8 as a movable member which is provided at the lower end of each leg 5 of the movable frame 6 so as to project inward and overlaps with each upper plate 7 on a vertical line.
And a bolt 9 that connects the upper plate 7 and the lower plate 8 to each other. As shown in FIG. 4 in detail, this aligning device includes an upper plate 7 attached to a pillar 1 of a fixed frame 3 and a lower plate 8 attached to a leg 5 of a movable frame 6 on both plates.
7 and 8 are connected by bolts 9 that are tiltably inserted, and the lower plate 8 is swingably suspended by the upper plate 7 so that the movable frame 6 can be horizontally displaced within the tilt range of the bolts 9. is there. Further, on the underframe 4 of the movable frame 6, guide plates 10 each having an inclination such that the upper part thereof expands outward are attached to the side end positions of the other corners except the carry-in part of the luggage 11.

When the luggage 11 conveyed by the forklift is loaded from the direction of the arrow in FIG. 3 and placed on the underframe 4 of the movable frame 6, even if the luggage 11 is not located right above the underframe 4,
That is, even if the luggage is out of the proper position,
When the lower end of the luggage 11 comes into contact with one of the guide plates 10 when the luggage 11 is lowered, the movable frame 6 pushes the guide plate 10 when the luggage 11 slides along the guide plate 10 and descends. The bolt 9 is displaced by following the tilting of the bolt 9 in the direction in which the guide plate 10 is pushed. Next, when the luggage 11 is placed on the underframe 4, the movable frame 6 is moved together with the luggage 11 and returned to the original position, so that the luggage 11 can be automatically centered. it can.

Even if the guide plate 10 is not provided, the luggage 11
If the movable frame 6 is moved in correspondence with the carry-in position of, the load 11 dropped on the underframe 4 can be automatically aligned.

[Problems to be Solved by the Invention] However, in the conventional centering device provided on the mounting table, since the movable frame 6 is hung by the bolt 9, the strength of the bolt 9 is weak against heavy objects. There is a problem, especially because the neck portion of the bolt 9 is weak, and therefore there is a problem in terms of strength and reliability when tilted and an unbalanced load acts on the neck portion.

Therefore, the present invention intends to provide an aligning device equipped with a suspending tool such as the above-mentioned mounting table or a crane so as to exhibit an aligning function and capable of obtaining high strength reliability. is there.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a through hole in a fixing member disposed in an upper portion, and a cover casing is provided on an upper surface of the above fixing member at a position surrounding the through hole. A universal joint which is erected upright and is housed in the cover casing and arranged in the vertical direction through the through hole is hung with its upper end fixed to the upper end of the cover casing, and the lower end of the hung universal joint. Is fixed to a movable member arranged below the fixed member.

[Operation] Since the movable member is suspended by the universal joint from the cover casing on the fixed member, the movable member can be freely displaced in the horizontal direction within a range in which the universal joint can move in the horizontal direction within the through hole of the fixed member.
At this time, any unbalanced load does not act on the fixed portion between the universal joint and the movable member and the fixed portion between the universal joint and the fixed member side, so that high strength reliability can be obtained.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. Like the mounting table shown in FIGS. 2 and 3, the movable frame 6 is floated on the fixed frame 3 and each of the fixed frames 3 is arranged. An upper plate 7 as a fixed member provided at the upper end of the column 1 and a lower plate 8 as a movable member provided at the lower end of each leg 5 of the movable frame 6 are arranged so as to be vertically overlapped, The case where the lower plate 8 is suspended from the plate 7 is applied to a table having a structure. A through hole 12 having a required diameter is provided in the upper plate 7 as the fixing member, and the through hole 12 of the upper plate 7 is provided.
A cover casing 13 made of a pipe having a mounting seat 13a attached at one end (upper end) is erected on the upper surface of the position surrounding the 15 are arranged vertically and stored, and the upper end of the universal joint 15 is fixed to the cover casing 13
Through the hole 16 of the mounting seat 13a, and fix it using the nut 17 on the mounting seat 13a. Further, the lower end of the universal joint 15 is also passed through the hole 18 provided in the lower plate 8 in the same manner. The lower plate 8 is fixed at 17, and the lower plate 8 is suspended from the cover casing 13 on the upper plate 7 by a universal joint 15 so that the lower plate 8 can be freely displaced in the horizontal direction within the range of the gap between the universal joint 15 and the through hole 12. To do so.

In the above structure, the lower plate 8 is the upper plate 7
The mounting seat 13 is located inside the cover casing 13 provided above.
Since it is suspended by the universal joint 15 fixed to a, the outer surface of the universal joint 15 and the inner wall of the cover casing 13 and the through hole 12 of the upper plate 7
Since the universal joint 15 can move within the range of the gap between the inner wall of the unit and the inner wall, it can be freely displaced in the horizontal direction. Therefore, when the luggage 11 is unloaded and placed on the underframe 4 as shown in FIG. 2 using a forklift, the luggage 11 is roughly placed, that is, the luggage 11 is underlaid.
Even when the movable frame is placed at a position where it interferes with the upper guide plate 10, the guide plate 10 is pushed when the load 11 descends by its own weight, as in the case of the conventional example shown in FIGS. 2 and 3. 8
However, the movable frame 6 is then returned to its original position so that the luggage 11 can be automatically centered.
At this time, the load on the lower plate 8 side acts on the universal joint 15, but since an unbalanced load does not concentrate on the universal joint 15, the mounting seat 13a, and the fixed portion to the lower plate 8, the strength is reduced. High reliability is obtained. Also, the above universal joint 15
Since it is housed in the cover casing 13, it is possible to reduce the occurrence of failures without any external influence.

In the above embodiment, the case where the aligning device of the present invention is mounted on the stand is shown. For example, the aligning device is mounted on the portion of the suspending tool such as a crane and is used for aligning the load hung by the suspending tool. Of course, various changes can be made without departing from the scope of the present invention.

[Advantage of the Invention] As described above, according to the aligning device of the present invention, the movable member is hung by the fixed member by using the universal joint, so that the load handled by the movable member is deformed by the universal joint. The core can be surely aligned, and it has high strength reliability against a load.
Since the universal joint is housed in the cover casing, it is possible to reduce the occurrence of failures without being affected by external influences. Furthermore, due to its simple structure, special processing is required for alignment. It has excellent effects such as low cost and low cost.
