Next, the inspection discriminating device 5 provided on the downstream side of the conveyance of the injection cleaning device 4A will be described.

The inspection / discrimination device 5 is constructed to inspect both the vertical warp of the sheet pile 1 in the longitudinal direction and the warp of the sheet pile 1 in the left / right direction, and discriminate whether or not it is within the allowable range. ing.

First, the operation of detecting the upper and lower warpage of the sheet pile 1 in the longitudinal direction will be described.

Although the sheet pile 1 is temporarily stopped at the predetermined position,
In the case of this structure, the lower support roller 17 has the positioning portion 5
It will function as A.

That is, as shown in FIGS. 10 to 12, the supporting rollers 17 erected at a constant interval support the sheet pile 1 in a horizontal state, and this supporting surface serves as a reference, and this supporting surface serves as a reference. It is detected how the sheet pile 1 placed on the top is distorted in the vertical direction.

Specifically, contact bodies 23 capable of contacting the upper surface of the sheet pile 1 are provided at several positions in the length direction of the sheet pile 1 as the inspection device 5B so as to be movable in contact therewith.

The principle is that, if the sheet pile 1 is not distorted and is horizontally positioned with a predetermined thickness, the contact members 23 are brought into contact with each other or closely spaced at predetermined intervals, but if they are distorted vertically. Since a part thereof projects upward, the abutment body 23 abuts before descending to a predetermined position.

By detecting this, the vertical distortion of the sheet pile 1 is detected.

In this embodiment, the abutting member 23 is provided on each rotary shaft 24 which is installed above the sheet pile 1 at a predetermined interval so as to be able to rotate up and down, and the rotary lever 25 is conveyed to each rotary shaft 24. Device 2
It hangs down from the side.

When the rotary levers 25 are moved back and forth to rotate the rotary shafts 24 to lower the contact bodies 23 and the contact bodies 23 contact the sheet pile 1, the horizontal movement of the rotary levers 25 is achieved. Detect the amount of movement. When the turning lever 25 moves by a predetermined amount and the sensor 26 detects and operates, it is found that the contact body 23 has sufficiently lowered, and it is determined that there is no abnormality at that position, and conversely the moving amount of the turning lever 25 is small. When the sensor 26 does not perform the detection operation, it can be understood that the contact body 23 has come into contact with the sheet pile 1 before the contact body 23 has sufficiently descended, and at that position, it is determined that the sheet pile 1 is largely curved upward.

Therefore, by disposing the sensor 26 at the limit position corresponding to the allowable range, it is judged whether or not the warp condition of the sheet pile 1 is within the allowable range.

The degree of distortion of the sheet pile 1 in the left-right direction is determined by the same principle.

Specifically, as shown in FIGS. 13 and 14, an abutting portion for abutting one side edge of the sheet pile 1 is provided as a positioning portion 5A on the frame portion on one side of the conveying device 2, and the inspection device 5B is provided on the opposite side. As is the case with the above-described sled condition detection, a contact body 23 'that can contact the opposite edge of the sheet pile 1 is provided.

Similarly, a sensor detects the amount of movement of the rotary lever 25 'for abutting and moving the abutting body 23', and whether or not the degree of distortion is within an allowable range is determined by whether or not the sensor is operated. Determine.

In the figure, reference numeral 28 is a lever actuating drive source for moving the support rod 29 and causing the turning lever 25 to hang down by its own weight to turn the turning shaft 24.

Next, the discharging device 6 will be described.

In this embodiment, the inspection discriminating device 5 is not provided, but the sheet pile 1 inspected and discriminated by the inspection discriminating device 5 is provided at a downstream position slightly conveyed.

In the present embodiment, the storage unit 27 is provided on the left and right with the carrying device 2 as a boundary, and when the inspection determination device 5 determines that the product is a non-defective product within the allowable range, the storage unit 27 on one side is moved to the storage unit 27. When the product is sorted and discharged, and conversely is determined to be a defective product outside the allowable range, the product is sorted and discharged to the opposite side storage unit 27.

This inspection / discrimination device 5 is the above-mentioned supply device 3
In the same configuration as described above, the sheet pile 1 on the transport device 2 is locked by the sheet pile locking and holding mechanism 8, and then the moving mechanism 9 sorts and discharges the sheet pile to the predetermined storage section 27 (right and left) according to the above instruction. As shown in, the sheet piles 1 are stacked and stored so that the sheet piles 1 are staggered slightly to the left and right.

Therefore, the used sheet pile 1 which is successively conveyed.
After being automatically washed, the inspection / discrimination device 5 inspects the degree of deformation, and according to the discrimination result of the inspection / discrimination device 5, the product is classified into a good product and a defective product.

Therefore, only good products can be sorted and stored for reuse, and defective products can be stored so that they can be discarded or corrected.

It should be noted that instead of such a left-right distribution method,
Only one of the good product and the defective product may be directly conveyed and discharged by the conveying device 2.

[0055]

Since the present invention is constructed as described above, the used sheet piles that have been collected are automatically washed one after another to wash away the mud, and the degree of deformation of the washed sheet piles is automatically changed. It becomes an extremely excellent sheet pile cleaning and inspection device that is inspected and is automatically sorted into good products and defective products by this inspection.

Therefore, not only the manual work for collecting and washing the sheet pile, which was conventionally done manually, can be performed very efficiently, but also the degree of deformation is automatically inspected one after another, and only non-defective products can be re-used for standby. It becomes an extremely excellent sheet pile cleaning and inspection device.
