Abstract

PURPOSE:To optimize the dimensional structure of an aligning apparatus and the quantity of steel pieces thrown by providing a basket, the side of which is a band-like plate capable of turning, and gradually opening the side with the rising of the basket to discharge a suitable quantity of steel pieces without reversing. CONSTITUTION:A basket 1b storing steel pieces is raised by an endless chain 2a turned in the arrow direction by an electric motor. When the chain 2a is turn ed and the upper end band plate 12 of the basket 1b reaches an upper chain wheel 8, the basket 1b is turned with the chain 2a, so that the wall surface of the basket on guide frame 3 side is opened from the upper end, whereby the stored steel pieces are gradually crumbled from the upper part thereof and dropped in direction of an arrow C according to the elevating speed, and slided along a chute 4 in direction of an arrow D to be discharged in an aligning apparatus 5. The discharge quantity to the aligning apparatus 5 can be adjusted by controlling the turning speed of the band plate 12 to vary the opening speed of the basket 1b. Accordingly, the unreasonable dimensional structure of the alingning apparatus is not required, and a cradle is prevented from damage.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steel billet, etc., which feeds steel billets, such as billets for forging, into a heating furnace that heats them up to a predetermined temperature. Related to transport basket elevators.

Conventionally, furnaces that heat billets and other steel pieces for forging were often discharged by dropping them on a sloping 7-ute, etc. due to the need for heat resistance in order to supply the heated material to the forging press. The location was always high. For this reason, the steel billet aligning device that supplies the heating furnace was also installed at a high location to keep it on the same level as the heating furnace. Therefore, a crane or a basket elevator or the like is used to feed the steel pieces into the alignment device, and in such cases, the basket elevator has mainly been used.

FIG. 1 is a side view showing an example of a conventional basket elevator for conveying steel billets. As shown in the figure, a basket (1) containing steel pieces is fixed to a part of a vertical endless conveyor (2), and is raised and lowered by normal and reverse rotation of the vertical endless conveyor (2). At the position of the rising end (1a), the steel pieces are discharged, slide on the chute (4) in the {circle around (4)} direction, and are thrown into the alignment device (5) K installed on the pedestal (6). However, when the basket (1) reaches the ascending end (1B), it has to be reversed approximately 165 degrees to discharge the steel pieces, which results in the steel pieces gaining an initial velocity and the head becoming larger than necessary. Because of this, the shock is large when it is thrown into the alignment device (5), and the pedestal in the alignment device (5) is easily damaged, and the service life of the pedestal is significantly shortened due to deformation of the pedestal. Furthermore, unless the amount of steel billets fed into the alignment device (5) cannot be controlled, all the steel billets in the basket (1) must be fed in at once, and the billet capacity of the alignment device (5) will exceed the basket (1). It has the disadvantage that it requires the same capacity as the conventional one, and requires an excessively large dimensional structure. As a result, the difference in weight between when the aligning device (5) is full and when the steel billet is reduced becomes extremely large, and the function of the aligning device (5) changes in response to weight fluctuations, making it unstable. The alignment device (5) has become complicated, such as by providing a control device according to the configuration. In the figure, (3) is the guide frame, (7), (8)
indicates chain foil.

The present invention has been made in order to solve the above-mentioned drawbacks, and provides a basket elevator for conveying steel billets, in which the alignment device has an appropriate dimensional structure, is free from damage, is simple, and does not cause unnecessary jamming of steel billets. The purpose is to obtain.

In order to achieve the above object, the present invention has a layered structure that can be wound on the side surface of the basket, and as the basket rises, the side surface gradually opens and the steel pieces are gradually discharged without reversing the basket. The present invention provides a basket elevator for transporting steel billets.

The present invention will be explained below using the drawings.

2 and 3 are side views showing an embodiment of the present invention. As shown in the figure, the guide frame (3) of Basquera) (1b)
) side wall is a band plate (6) fixed to an endless chino (2a) K.
) are attached in a blind-like manner. No (suketsu)
(1b) is a part of the endless chino (2a) and the connecting fitting (
11), and is structured to move up and down along the guide frame (3) in response to forward or reverse rotation of the endless chino (2a).

A detailed explanation of the present invention configured as above is as follows. The basket (1b) containing the steel pieces is raised by an electric motor (not shown) that rotates the endless engine (2) in the direction of arrow 0. The endless chino (2a) is rotated,
When the strip plate (B) at the upper end of Basquera (Ib) reaches the upper Cheno foil (8), the Sket (1b: is wound together with the endless Cheno foil (2a). Therefore, the guide frame (3) (1b) The wall surface opens from the top, and the stored steel pieces fall from the top in a manner that gradually collapses in the O direction according to the lifting speed.
It slides on the chute (4) in the O direction and is discharged into the alignment device (5). The discharge amount into the alignment device (5) is controlled by the strip plate (
By controlling the winding speed of (b),
1b) can be adjusted by changing the opening speed.

In addition, if a freely rotating swing chute α→ is provided at the bottom of the basket (1b), when the basket (1b) rises to the top end, the swing chute (1b) shown in Figure 6 will be the same. It is possible to prevent a piece of steel falling in the direction O from remaining stuck in the gap tA created between the wound portion of the strip plate (6) and the wound portion of the strip plate (6). And for endless Cheno (2a
) side, making it possible to completely discharge the steel pieces in (1b).

In the above explanation, the case where a band plate is used on the basket wall portion on the guide frame side is shown, but the present invention is not limited to this, and the present invention is not limited to this, and the present invention is not limited to this. It may also constitute a wall surface.

As is clear from the above description, according to the present invention, the dimensional structure of the alignment device is appropriate, there is no damage, and it is simple, and it is also possible to achieve remarkable effects such as eliminating unnecessary jamming of steel pieces. can.
