Description

  The present invention relates to a metal conveying apparatus and a conveying method. In particular, the present invention relates to a transport apparatus and a transport method for transporting an irregularly shaped metal such as a metal scrap or a metal scrap plate cut into a certain size.

  As a conventional apparatus for conveying an irregularly shaped metal, a rubber belt conveyor (hereinafter, Patent Document 1) or a metal conveyor (chip conveyor) has been used.

  However, in the conventional belt-type conveyor device, when the product to be conveyed is an irregularly shaped metal scrap or the like, the rubber belt is damaged at a sharp portion of the metal scrap, and the operation for a long time cannot be performed.

Further, metal conveyors (chip conveyors) are repeatedly loaded with heavy metal scraps, so that the deformation progresses and this is not suitable for a long time operation.

Japanese Patent Laid-Open No. 7-267315

  It is an object of the present invention to provide a transport apparatus and a transport method that can operate the transport of irregular shaped metal scrap without performing maintenance for a long time.

  An object of the present invention is to provide a transport apparatus and a transport method that can be bent and transported in a free direction with simple equipment.

  The present invention is directed to a metal conveying apparatus for placing and feeding an irregularly shaped metal to such a problem, comprising an inclined iron plate-like feeding means, and the iron plate-like feeding means in front and rear. Provided with a drive means (15) for moving the metal, and the drive means for moving an irregularly shaped metal to a low-inclined side in accordance with the law of inertia. To do.

  The inclination of the iron plate-like feeding means is advantageously 5 to 10 degrees with respect to the horizontal. If the inclination of the feeding means (feeding device) is 5 degrees or less, a non-slip shape with a large contact area that is not slippery and heavy objects cannot be transported below the inclination due to contact resistance. On the contrary, when the angle of the feeding means (feeding device) is 10 degrees or more, an irregular shape with good rolling is likely to roll off, which is dangerous. In addition, the height (head) is necessary to secure the transport distance in the first place.

  It is further advantageous that the inclination of the iron plate-like feeding means is about 7 degrees with respect to the horizontal. This is because the inventor has confirmed through experiments that the angle is suitable for conveying metal scrap steel plates.

  The iron plate-like feeding means can be a thick plate containing high Mn steel, in which case wear and deformation are reduced.

  The iron plate-like feeding means can be widened in this case, and in this case, the irregularly shaped metal can be prevented from accumulating in one place at the arrival point, and the irregularly shaped metal at the arrival point can be prevented. So that you can work without moving over and over again.

  The iron plate-like feeding means can form a curved conveyance path, and in this case, it can be conveyed not only in a linear direction but also in an arbitrary direction, and a process line arranged not curved but curved can be used. It is also possible to go through.

  The conveying device according to the present invention is configured such that the conveying amount for conveying the irregular-shaped metal is the number of times the driving means (15) moves the iron plate-like feeding means (11) back and forth (for example, sliding per minute). It is possible to provide a conveyance amount control means that can be arbitrarily set according to the number of times). In this case, the conveyance amount can be adjusted. The conveyance amount control means (not shown) itself can be clearly implemented by those skilled in the art by combining a driving means (motor 15) and a known continuously variable transmission (not shown) or changing the rotational speed of the motor itself. It will not be described in detail here.

  In the present invention, the irregularly shaped metal to be conveyed or fed can be a large piece of metal. Furthermore, depending on the feeding means other than the iron plate shape, it may be an irregularly shaped metal piece that is sufficiently large to make it difficult to operate for a long time.

  The present invention is also a method of transporting a metal by an inclined iron plate-like feeding device for placing and feeding an irregularly shaped metal, wherein the iron plate-like feeding device is moved back and forth by a driving device. The present invention provides a method for transporting a metal, characterized in that an irregularly shaped metal is moved to a low slope side in accordance with the law of inertia.

According to this invention, there exists an advantage that continuous operation becomes easy compared with a belt conveyor type.
Due to the conveyance using the table (feeding means) 11, troubles such as catching and biting that often occur on the rotary conveyor are eliminated. In addition, the consumption of each component is extremely reduced.
In addition, because high-Mn (manganese) steel with a thick plate is used as the feeding device (feeding means), there is almost no wear or deformation, and continuous operation is possible as long as there is no problem with the drive device that slides the feeding device back and forth. Became possible.
Further, since it is a swinging type that moves the feeding means back and forth, there is also an advantage that no vibration noise is involved such as vibration or a vibration conveyor using a Eurus motor.
In addition, the feeding device (feeding means) spreads out to prevent the irregularly shaped metal from accumulating in one place at the arrival point, thereby repeatedly moving the irregularly shaped metal at the arrival point. It was possible to work without having to do it, and work efficiency was improved.
Further, by changing the number of rotations of the electric motor 15 or the like, the number of times of moving (swinging) the feeding device (feeding means) back and forth is arbitrarily changed, and a cutting device or the like in the pre-process of metal scrap steel plate recycling The conveyance amount can be arbitrarily set and changed according to the production amount, and the clogging due to the conveyance is eliminated.

In the best mode, by using a high manganese type wear-resistant steel plate as the material of the feeding means (table type feeding device) 11, the weight of the table is halved and wear due to sliding of the metal piece to be conveyed is prevented. Is also tolerable. Specifically, the hardness of the high manganese-based wear-resistant steel plate of the feeding means 11 is HB (Prinel) 500, and the metal to be conveyed is SS400, SPCC hardness HB (Prinel) 120 (based on tensile strength) (Estimated value).
In addition, a hydraulic motor that generates a large torque even at a low speed is adopted as the drive source 15 to enable a continuously variable speed of swinging speed and to perform safe and reliable conveyance.

  In the configuration of FIG. 1, an irregularly shaped metal 10 is placed on an iron plate-like feeding device 11 having an inclination of about 7 °, and the feeding device 11 is moved back and forth so that the irregularly shaped metal 10 is formed. It is a device that conveys using the movement to the lower slope side according to the law of inertia. Since the feeding device 11 uses high-Mn steel having a thick plate, there is no wear or deformation, and the driving device 15 that slides the feeding device 11 back and forth can operate continuously as long as there is no problem.

In the embodiment of FIG. 2, the belt type conveyor and chip conveyor, which are conventional conveyors, are only in the linear direction, and it is necessary to overlap two conveyors in order to change (bend) the conveyance direction. The present invention relates to the present invention which has been overcome and can be adapted to a bent process line by bending a transfer unit so that only one unit can be transferred in a free direction.
The present embodiment is an example in which an iron plate-like feeding means 11 (that is, a pedestal or a tray portion 11 with a bent guard rail 11b) is bent. As a result, the direction of the metal can be changed in the direction of the arrow 16, non-linear movement is possible, and a curved process line can be handled. Further, even if the metal is shifted to both ends of the tray part 11, it can be dispersed.
In addition, when the inclination with respect to the horizontal is 7 degrees, it has been confirmed that the sheet is experimentally conveyed up to a bending angle of 45 degrees with respect to the conveying direction, and two portions with an angle of 45 degrees are provided. Thus, the conveyance direction can be changed to 90 degrees.
