DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram showing the overall configuration of a sheet inspection apparatus, FIG. 2 is a side view of the apparatus, and FIG. 4 is a sectional view taken along the arrow line BB in FIG. 3, and FIG. 5 is an operation explanatory view of the sheet conveying conveyor. By the way, the configuration of the sheet inspection apparatus in this embodiment and the functions related to the sheet traveling in the apparatus are the same as those of the prior art described with reference to FIG. Omitted. According to the present invention, a good paper 10 and a defective paper 1 are determined by carrying-in setting of a stacking sheet 9 which is an object to be inspected required in a sheet inspecting apparatus and inspection.
The present invention proposes an improvement relating to automation of a series of sheet conveyance such as unloading of sheets which are sorted into one and stacked at a predetermined position, and the configuration and functions thereof will be described below.

As shown in FIG. 5, the apparatus comprises a sheet feeding section 1 and a second sheet feeding section.
In the sheet stacking section 2, the conveyors 4, 5 reciprocatingly move the carrier plate 3 in the sheet advancing direction, and the first sheet stacking section 6 located substantially at the center of the two conveyors 4, 5, are perpendicular to the sheet advancing direction. And a conveyor 7 for reciprocating the carrier plate 3 in the direction. In the sheet feeding section 1, first, at a position A in the drawing, a sheet receiving table 8 in which sheets to be inspected are stacked and held is carried into a predetermined position on the carrier plate 3. Subsequently, it is moved to the operating position via the conveyor 4, that is, the position B in the figure. At this position, the carrier plate 3 is lifted to an initial height through a carrier plate elevating device (not shown), and the raised state (amount) is adjusted to correct the loss of the upper end due to sheet feeding from the uppermost stage. It is controlled.

The empty sheet receiving table 8 after all the sheets are carried out by the operation is placed and delivered on the conveyor 4 by the lowering of the elevating device together with the carrier plate 3.
It is transferred to the standby position C in the figure. At the same time, the stacking sheet 9 prepared at the initial standby position A is transferred to the operation position, that is, B in the drawing, and is lifted to a predetermined position via the carrier plate elevating position as described above. The carrier plate 3 waiting at the position C is returned to the initial standby position A through the gap formed below the portion B, and waits for the next stacking sheet 9 to be carried in with the sheet receiving tray 8 being discharged. The above behavior is sequentially repeated, and the sheet 9 is supplied to the sheet feeding unit 1 in a substantially continuous state.

Next, the functions of the first sheet stacking section 6 and the second sheet stacking section 2 of the same type will be described. The position B during the operation is where the sheets 10 and 11 appropriately selected at the end of the inspection are dropped and stacked, and the carrier plate 3 on which the sheet receiving table 8 is placed is first moved in the same manner as the sheet feeding section 1. After being set to a predetermined height via a lifting device (see FIG. 4), the sheet is lowered in conjunction with the drop of the sheet. During this time, the empty sheet receiving table 8 is transported together with the carrier plate 3 to a position C in the figure through a gap formed below.
When a certain number of sheets are reached by the stack of falling sheets,
Lower the carrier plate 3 and place it on the conveyor,
After the completion of inspection A in FIG.

At the same time, the carrier plate 3 prepared at the position C is transferred to the operation position, and the sheets which are lifted to the predetermined height and fall sequentially afterwards are stacked. The stacked sheets waiting at the position A are transported to the outside via means not shown, for example, a forklift or the like, and the empty carrier plate 3 is stacked with the next sheet receiving table 8 placed thereon. After passing below the position B in the middle of the weight, it is transported to the position C and stands by. The above behavior is sequentially repeated, and the sorted stacked sheets are continuously carried out. Various types of conveyors such as a roll type and a belt type are conceivable. The present invention is configured and functions as in the above-described embodiment, and the loading and unloading of the stacked sheets required in the sheet inspection apparatus can be automatically performed.

[0013]

As described in detail above, the stacked sheet conveying conveyor of the present invention is provided with three positions, an initial standby position, a subsequent operation position, and a subsequent operation completion standby position, on the same plane. When the operating carrier plate is lifted to a predetermined position by the carrier plate elevating device at the position, the carrier plate at the operation completion standby position can pass through a gap formed below the carrier plate,
Since the structure is operable in the reverse direction to the initial standby position, processing of the carrier plate and carry-in processing of the carrier plate for the next operation can be performed only at the initial standby position. Therefore, the space for carrying the carrier plate is reduced. As a result, it is possible to greatly reduce the labor required for the work, and it is possible to expect a great effect economically and productively, such as shortening the time required for the work.
