<Means for Solving the Problems> The present invention provides a method in which a continuously processed coiled strip is transported by a transport roller and then cut by a shear to collect a sample material. The height of the upper surface of the strip is used as the pass line of the stamp, and a belt conveyor with a plurality of electromagnets arranged on the lower surface is installed, and this belt conveyor is rotated in the normal direction when performing normal processing on the strip. When transporting the strip and cutting out the sample material from the strip, the entrance side of the strip is raised and reversely rotated to attract and move the sample material with the electromagnet, and the sample material receiver is discharged onto the table at a predetermined position. 1. A method for collecting sample material in a strip processing line characterized by , an endless belt conveyor whose upper surface is arranged at the same height as the strip pass line and can freely rotate in forward and reverse directions immediately downstream of the shear; and an endless belt conveyor arranged along the longitudinal direction of the lower surface of the belt conveyor. a plurality of electromagnets, a machine end detection sensor that is provided downstream of the 1i'fyN stone and detects the tip of the sample material, a lifting means that allows the upstream side of the belt conhair to be raised and lowered; A sample material collecting device in a strip processing line is characterized in that a sample material receiver provided below a belt conveyor and accommodating the sample material is comprised of a table.

<Function> According to the present invention, an endless belt conveyor whose upper surface is at the same height as the pass line of the strip and is capable of forward and reverse rotation is disposed immediately downstream of the shear that cuts the sample material. Therefore, when performing normal processing on a strip, the strip is conveyed by rotating the belt conveyor in the forward direction, and when cutting sample material from the strip, by raising the entrance side of the belt conveyor and rotating it in the opposite direction. Sample material can be collected while being attracted using a 1X magnet.

<Examples> Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic diagram showing the overall configuration of an embodiment of the present invention, and FIG. 2 is a side view showing an enlarged main part thereof.

As shown in the figure, a sample collection device 20 is provided immediately downstream of the shear 4. This device is composed of an endless belt conveyor 21 and rollers 22, 23, and the upper surface 21a of the belt conveyor 21 is connected to the pass line P of the strip 1.
It is arranged at the same height as L, and can be rotated forward and backward by a drive device (not shown).

And inside the lower surface 21b of the belt conveyor 21,
A plurality of electromagnets 24 are arranged along the longitudinal direction in a staggered manner in the width direction as shown in FIG. A detection sensor 25 is provided.

In the figure, 26 is an elevating means such as a fluid pressure cylinder that allows the roller 22 on the upstream side of the belt conveyor 21 to be raised and lowered, and 27 is an elevating means such as a fluid pressure cylinder provided below the belt conveyor 21 for storing the sample material I7. The sample material holder, such as a trolley, is a stand.

The operation of the sample collection device 2o configured in this way will be described below.

(2) First, when performing normal processing on the strip 1, the strip 1 is transported while rotating in synchronization with the speed of the transport roller 3, with the upper surface 21a of the belt conveyor 21 being at the same height as the pass line PL.

■ When a sample material collection command is issued, the transport roller 3
is temporarily stopped and the shear 4 is activated to cut the strip ■. At the same time, the elevating means 26 is operated to lift the boot IJ2.
2 above the pass line PL, the belt conveyor 21 is reversely rotated, and the tip of the cut strip 1 is guided to the lower surface 21b of the belt conveyor 21 (
(See Figure 4(a)).

- When the strip 1 enters the lower surface 21b of the belt conveyor 21, the electromagnet 26 is immediately energized to attract and feed the sample material 17, as shown in FIG. It is stopped and cut into a predetermined length using a shear 4.

■ The belt conveyor 21 is further rotated in the reverse direction to further feed the sample material 17, and when the plate edge detection sensor 25 detects the tip of the sample material 17, the belt conveyor 21 is stopped and the electromagnet 26 is turned on after a predetermined time has elapsed. After demagnetization, the sample material 17 is dropped onto the table 27 and placed on the sample material receiver, as shown in FIG. 4(C).

■ Also, when a detection signal from the plate edge detection sensor 25 is issued, the elevating means 26 operates to move the roller 22 to the pass line P.
By lowering the strip to L and rotating the belt conveyor 21 in the forward direction, the belt conveyor 21 is prepared for processing the next strip 1.

(2) On the other hand, the sample material tray 27 on which the sample material 17 is placed is pulled out of the processing line and transported to a predetermined location to complete sample material collection.

<Effects of the Invention> As explained above, according to the present invention, the sample collection device is disposed in the conveyance line for continuously processed strips to collect the sample material, thereby saving line space. It is also possible to save on equipment costs.
