Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevating type piling device that temporarily stores shaped steel sections conveyed through rolling, straightening and inspection processes on an inspection floor or sorting floor according to their size.

During the transportation process, rolled steel shapes are formed through a straightening machine, and then sent out through an inspection process.In the past, products that were delivered at random were sorted into different pilers according to length, and the same Either a method is adopted in which products of the same length are piled and then dispensed as appropriate, or the products being transported are temporarily placed on a specific trolley and products of the same length to be bundled are sequentially dispensed from among them. The method was adopted. However, in the former case, it is necessary to install a piler corresponding to the length of the product, and in the latter case, the width of the truck is long, so the equipment is large-scale and wide. In addition to requiring space, the latter has many problems such as the impossibility of piling, leaving room for improvement.This invention was made with the aim of solving the above conventional problems. It is something. In other words, the present invention provides a product inspection floor or a sorting floor, in which a vertical sorting machine with multiple skid-like piling shelves is provided with a platform, and has an elevating function that allows any shelf surface to be connected to the inspection floor; The special feature of this system is that it has a function of sequentially polymerizing and piling products delivered on a shelf, and the present invention will be explained below based on an illustrated embodiment.

As shown in Figures 1 and 2, (1) is supported at a predetermined interval, and is integrally connected and fixed to the skid-shaped piling shelves (2) with multiple stages in the vertical direction. The underframe (1) consists of support rods (3), which are made by cross-cutting the skid (a) constituting the test end at a suitable place, standing it upright at this place, and then cutting the lower half of the skid (a). It is housed in a framework (4) assembled in a space dug deep from the floor so that it can be raised and lowered freely, and guide rollers (5) are installed at the four corners of the frame (4) on the inside of the supports.
is rotatably provided.

(6) is a screw shaft that stands upright on both sides of the framework (4) and has a nut ()) fixed to all or some side edges of the piling shelf (2) threaded through it; 6) is the motor (8) mounted on the top of the framework (4).
The rotation of the worm is transmitted through a gear mechanism (9) consisting of a worm, an ohm wheel, and all gears, etc., and rotates forward and backward to move the underframe (1) up and down. Squeeze any position on the shelf (2),
It is possible to continuously oppose the do (&) plane in a flush manner, and furthermore, it is possible to provide a finely adjusted lifting and lowering movement. Although a threaded shaft (6) is used in the embodiment, it is also possible to provide a rack on the frame side and rotate a pinion that meshes with the rack, or to employ means such as chain drive. The choice is free. In addition, a weight α [is suspended from both sides of the framework (4) via wires (not shown),
The tip of this wire is connected to the underframe (1) through a turning pulley (not shown) provided at the top of the framework (4), thereby reducing the weight of the underframe (1) and driving it to move up and down. The load acting on the mechanism can be reduced, which makes the design selection of the drive mechanism easier.

Each of the piling shelves (2) in the underframe (1) is provided with a so-called stacking mechanism that sequentially polymerizes the shaped steel (A) fed therein. By the way, several types of this type steel stacking mechanism have been proposed in the past, but in the embodiment of this invention, a mechanism that adopts the simplest mechanism that is compatible with the function of the elevating underframe (1) is used. Illustrate. In other words, the mechanism is such that a first support pin (11) and a second support pin α6, which are rotatably supported, are arranged at appropriate intervals at a position extremely close to the entrance of each piling shelf (2). A spring (B) is connected to the lower end of the support pin (16) and is always biased in the upright direction. However, in this case, it is necessary to adjust the feeding stroke of the section steel (A) into two stages, and if the feeding stroke is set to one quantitative stage, the method shown in Fig. 2 will be achieved. Connect the second support bottle to the first as shown.
The position of the support pin (b) may be different from that of the support pin (b).゛(B) is a shaped steel (A)
a feeding die for feeding the material to the piling shelf (2);
This is placed at least in two places on the left and right sides of the skid (&).
For example, it is attached to the tip of a sliding body (B) with a rack (B) on its back surface so that it can move up and down freely, and by rotating the pinion (B) that meshes with the rack (B) in the forward and reverse directions, it moves back and forth with a predetermined stroke. 〇 or (b), which is configured to move forward, moves the shaped steel (
This is a so-called dispensing claw for taking out A) directly onto the skid (&), and although it is not shown in the figure, it is an actuating shaft (E) that moves forward and backward through a rotating lever driven by a hydraulic cylinder. It is attached at the tip so that it can be raised or lowered freely. In addition, the above-mentioned feeding die (1c4) and the dispensing claw (b) are not connected to the shaped steel (A
), it passes by touching the back side of the object, and when the passage is completed, it automatically stands up by the action of the weight, and in this state, even if a load is applied, it will not fall to the opposite side. It has become. By the way, several types of such automatic claw restoring mechanisms and claw forward and backward movement mechanisms have already been proposed, and when carrying out this invention, it is only necessary to select and adopt an appropriate one among them. It is. Although not shown, a shaped steel transfer mechanism driven by a chain with claws, for example, is provided between the skids (1) on the feeding side.

FIG. 3 is an explanatory diagram of the piling operation when only the first support pin (support) is provided. That is, as shown in FIG.
When the height is the same as that of ) is lowered by the protrusion of the support pin α0 (the flange thickness of the C section steel (A)), and the next section steel (A) is fed in by the motion of the feeding die (B) corresponding to the stroke V). The shaped steel (A) fed in at this time overlaps the preceding shaped steel (A) by seven lunges and stops with the rear supported by support pins 01).

In particular, as shown in the same figure (c), the pile rack (2
) is raised to match the skid (&), and then the next section steel (A) is continuously fed into the stroke (4 → (L), as shown in ) to (E) in the same figure. It is fed by the movement of the mold (B).The shaped steel (A) being fed at this time pushes down the support pin (9) and enters below the preceding shaped steel (N), and after passing this shaped steel (A), The support pin αυ automatically stands up, and as shown in the same figure (f), the next section (n) is fed in.
It supports the rear of Shu.

Figure 4 shows the arrangement of support pins (B) (6) corresponding to the case where the feeding die α@ is always operated by a constant stroke (L), and shows the arrangement of the support pins (B) (6) that correspond to the case where the feeding die α@ is always operated by a constant stroke (L). )teeth,
As shown in Figure (A), the support pins are in the tilted position, and then as shown in Figure C), the piling shelf (2) is lowered by the protruding amount of the support pins (11). When the next section steel (&) is fed in, it becomes (B) to (C) in the same figure, and this (
At c), the support pin (16) also stands up, thereby supporting the rear end of the section steel (A).Next, as shown in the same figure), the piling shelf (2) is raised and restored, and then the next When the shaped steel (A) is fed in, it becomes as shown in the same figure (e), and from this state, the piling shelf (2) is lowered again and the next shaped steel is fed as shown in the same figure (f). The feeding operation continues until the state 111 shown in (c) is reached, and by sequentially repeating the above operations, the required piling is achieved.

As described in the embodiments above, this invention provides six frames having a large number of piling shelves that can be raised and lowered in a predetermined section of the skid, and further incorporates a mechanism for sequentially stacking and piling the shaped steel on each piling shelf. It has the function of being able to pile the shaped steel while sorting it according to its type and length, and because it has a vertical configuration, the space taken up by the chain is small, reducing setup costs. Furthermore, rationalization of work is achieved.
