Description

DETAILED DESCRIPTION OF THE INVENTION The present invention particularly relates to a piling method that enables high-speed sorting.

For example, it is common practice to continuously cut material from a strip steel plate using a cutting machine such as a flying shear and pile it in a bailer for temporary or long-term storage. Normally, the material to be cut is conveyed to a pipe by a belt conveyor or the like, and when a certain amount of material has been piled in the bailer, it is switched to another bailer and piled. By the way, when piling the material to be cut onto the bailer, if the speed of the material to be cut into the bailer exceeds a certain speed, the material being piled may be damaged or broken, so the cutting speed of the cutting machine should be adjusted accordingly. In the past, when it was desired to increase the piling speed, multiple conveyors were connected in series and the conveyance speed of the subsequent conveyor was reduced to reduce the final conveyance speed to the required piling speed.

However, in this conventional method, the conveyor speed is slow at the later stage, so the subsequent workpiece overlaps the preceding workpiece, making piling difficult. If the thickness of the plate is large, piling becomes more difficult, and therefore there is a certain limit to the deceleration range of the conveyor, which has the disadvantage that the cutting speed of the cutting machine cannot be increased beyond a certain speed. Ta.

The present invention was made in view of the above-mentioned circumstances, and the objects to be conveyed by a conveyor are sequentially transferred one by one to a plurality of sorting conveyors that are connected to the rear stage of the conveyor and run at a slower speed than the conveyor. It is an object of the present invention to provide a piling method that enables high-speed sorting while maintaining the conveyance speed required for each conveyor by sorting and repeating the sorting.

Hereinafter, one embodiment of the present invention will be described with reference to FIG.

FIG. 1 shows a schematic diagram of an embodiment of the method of the present invention. In the figure, 1 is a sorting device, and the material to be cut 8'f1 is continuously cut by a cutting machine 2 and transported at a conveying speed of 2v, and the material is sorted to a sorting destination of 2wR where both of the cutting speeds are V and 2wR. . A bailer 4a, 4b is provided at each sorting destination, and the speed at which the material to be cut 8 is carried into these bailers 4a, 4b is the above-mentioned piling speed V.

The sorting device 11 has conveyors aa and 6b with a conveyance speed of 2V connected in series to the outlet of the material to be cut of the cutting machine 2, a switching device 7a provided at the connection portion of these conveyors 6a and 6b, and this switching +! The conveyance path is switched by 47a. Further, the conveyor 6a has a conveyance speed of 2.
3 conveyors 9m, 10 via conveyor 8aTt
A sorting conveyor lla consisting of a and l1g is connected. Further, a sorting conveyor 12b consisting of three conveyors 9b, 10b, and llb is connected to the conveyor 6b via a conveyor 8b with a conveyance speed of 2v. In addition, magnetic conveyors are used for conveyors 9m and 9b.
It is designed to relay between the cable channels 8a and 10a and IJ8b and 10b. That is, conveyor 1
The conveyance speed of 0a*10b, lla, and llb is set to V, and therefore the conveyor 8a.

There is a difference in conveyance speed between Ion and between 8b and 10b, but relay magnet conveyors 9a and 9b are different from conveyor 8.
A, suck the workpiece 8 on 8b: yinbe+lOa,
10b, the material to be cut 8 is cut during relaying.
It is designed to prevent slippage.

Here, the switching device 72 is composed of a magnetic roll or a magnetic conveyor, and operates to alternately distribute 8 rt/piece of the cut materials from the conveyor 6a to the subsequent conveyor 6b and conveyor 8a. ing. That is, the material to be cut 8 cut by the cutting machine 2 is continuously conveyed by the conveyor 6m, and then the first material to be cut 8 is transferred to one conveyor 6b by switching the conveyance path by the switching device 7a. Then, the second workpiece 8 is conveyed to the other conveyor 8a, and this operation is repeated thereafter.

Therefore, conveyor 8a e g b Q conveying speed is 2v
Even if the conveyance speed force of the i-stage conveyor 10a and Rob is half V, the switching machine 7a4C alternately switches the conveyance path, so there is an inconvenience that the workpieces δ overlap each other during conveyance. does not occur.

In other words, even if the piling speed V is specified as a safe speed, the cutting processing speed of the cutting machine 2 can be increased to sv.
Magnet conveyors 18a and 18b are connected to 11b, respectively, and these conveyors 18a.

It is also possible to have a structure in which the bailers 5a and 5b are provided at the discharge end of the carrier 18b, respectively. In this case, conveyor 11a.

When one of the bylers 4a #4b5f connected to 11b becomes full, operate the magnetic feeders 18a and 18b and pile the other bylers 4a and 4b to the other pipes 5a and 5b. Continuous piling is possible by alternately using separate bailers.Also, in the above embodiment, the material to be cut 8 is sorted into two locations O, but as shown in FIG. A conveyor 6C is connected in series after the conveyor 6b,
By switching the conveyance path using a switch 117b provided at the connecting portion, it is also possible to have a configuration in which the materials are sorted into three destinations. In this case, the material to be cut 8 cut by the cutting machine 2 is sequentially sorted to three sorting destinations, so the material to be cut 8 is sequentially sorted into three sorting destinations.
The conveyance speed (pilink speed) of a, llb, and 11c is V
Even if the conveyance speed of conveyor 8a' at the start end is 8v
It is possible to increase the cutting processing speed of this knot cutting machine 2 to 8V. That is, cutting machine 2
If the gap between the cutting processing speed V and the 7-piling speed V is large, by preparing a sorting destination of V/vTi: a natural number determined by rounding up, the cutting machine can It is possible to increase the cutting processing speed of 2. Note that it is possible to increase the number of destinations as described above, and this expansion can be easily done without changing the arrangement of the conveyor in the previous stage.

In addition, the conveyance speed may be restricted due to, for example, the drive speed limit of the conveyor drive system or the total load of conveyed objects on the conveyor. may be set to a number with some margin, including these conditions.

Further, in each of the above embodiments, a magnetic roll or a magnetic conveyor is used as a switching device, but
Without being limited to this, for example, a purely mechanical flap or the like may be used. Further, the object to be transported is not limited to the material to be cut, and of course, other objects may be used.

As explained above, according to the high-speed sorting piling method according to the present invention, objects to be conveyed by a conveyor are transferred to a plurality of sorting conveyors that are connected to the rear stage of the conveyor and run at a slower speed than the conveyor. Since items are sorted one by one and this sorting is repeated, even if the conveyor speed of the conveyor is constant, the conveyance speed of the start conveyor can be increased without any problem by simply increasing the number of sorting conveyors. This has the advantage of enabling high-speed sorting.
