Description

[Detailed description of the invention] This invention relates to the invention of a long aluminum ingot loading device,
When loading or unloading billets or other long aluminum ingots cast in continuous casting equipment or other equipment onto trays for installation in a heat treatment furnace, or performing other cargo handling operations,
The object of the present invention is to provide a device that can smoothly and appropriately handle a large number of aluminum ingots and handle them in a preferred stacked state.

Billets and other castings that are cast usually turn into long ingots of several meters or longer, and such ingots are heat treated in a heat treatment furnace or the like prior to subsequent use. It is common that the material is used for extrusion molding and other processes, and in such cases it is necessary to carry out cargo handling to some extent.

Of course, cargo handling operations are essential when such ingots are transported by vehicle or other means, and conventionally such loading and unloading operations have been carried out using mechanisms such as forklifts or cranes. Since it is a long item and generally has a circular cross section, it has the property of being transferred, making it difficult to work with.

In particular, in order to prevent damage to the aluminum ingots and to create conditions that allow a favorable atmosphere to enter between the laminated aluminum ingots during the heat treatment as described above, spacers are used between the laminated aluminum ingots. However, such spacers must be handled by separate loading equipment or by human power, which makes the workability unfavorable from this point of view as well as being dangerous. There are disadvantages associated with this.

The present invention was devised after consideration to eliminate the disadvantages and shortcomings of the conventional ones as described above.

That is, an embodiment of the present invention as shown in the attached drawings will be described. A frame 1 having hanging portions ii and 1i formed on both ends is lifted by a suitable lifting mechanism. Guide portions 21 are provided oppositely on the inner sides of both ends, and these guide portions 21
．． 21, the slide body 2 is slidably engaged with the engaging part 22, and the interlocking shaft 16 is rotated by the rotation of the adjusting operation part 15 attached to one side of the frame 1 as shown in FIG. The threads 12a formed at both ends of the rotating shaft 12 are engaged with the female threads 20 of the slide body 2, respectively, and the adjustment operation part 15 rotates the rotating shaft 12.12. The sliding parts 2, 2 are brought close to each other or separated by the above-mentioned rotational operation, and the length of the aluminum ingot 6 can be quickly adjusted.

The intermediate portion of the gripping arm 10 is pivotally supported on the mounting seat 13 provided at each bottom of the slide body 2 as shown in FIG. 3 is attached to the top surface of the slide body 2 to form a gripping means, and FIG. 1 shows only one slide body 2 to avoid complication of illustration. The rond of the first operating cylinder 8 attached to the pivot support 1B that hangs over 2 is connected to the upper end of the gripping arm 10 as described above, and is arranged to open and close the gripping means. .

Further, adjustment pieces 31 that can be adjusted by adjustment means 32 are provided at both ends of the gripping part 3 so as to match the width of the plurality of aluminum ingots 6, 6, etc. to be gripped. It's empty.

Further, a rotating shaft 23 attached to the base end of the locking member I is attached to the support seat 11 provided on the upper surface of the sliding member body 2, and an operating arm 24 fixed to the intermediate portion of the rotating shaft 23 is attached to the supporting seat 11 provided on the upper surface of the sliding member body 2. It is connected to a second operating cylinder 9 mounted on a mounting seat 19 on the body 2, and is raised and lowered as shown by solid lines and imaginary lines in FIG. It is housed so as to lock onto the upper end of the gripping arm 10.

First, spacer members 5 to be interposed between the stacked aluminum ingots 6 in a direction crossing the length direction of the aluminum ingots 6 are placed on both sides of the frame 1 described above.
A plurality of hanging means 4, 4... connected as shown in the figure.
・are arranged respectively.

When using the cargo handling apparatus of the present invention as described above, the gripping means is operated by the operating cylinder 8 to grasp both ends of a large number of aluminum ingots 6, 6, etc. arranged as shown in FIG. It is clear that the material can be gripped with its gripping parts 3, 3, thereby requiring at least two to three workers in the conventional method as described above,
In addition, the ingot loading and unloading work, which is inefficient and involves some degree of danger, can be carried out mechanically by one operator smoothly and with sufficient safety. Since the spacer member 5 to be interposed between the laminated ingots 6 can also be loaded and unloaded at the same time using the hanging means 4゜4... arranged on both sides, there is no need for a worker to handle the spacer member. This method allows the aluminum ingots to be easily formed into a laminated state without damaging them, and in particular, when such aluminum ingots are loaded on a trade to be charged into a heat treatment furnace, the heat treatment atmosphere can be properly controlled. This invention has the effect of automatically forming a laminated state in a state where smooth heat treatment can be performed by entering the layer between the layers, and significantly shortening the working time. It is.
