FIG. 1 is a schematic view showing a single-wafer separating apparatus according to a first embodiment, FIG. 2 is a schematic view showing a single-wafer separating apparatus according to a second embodiment, and FIG. Schematic diagram showing an example of separation,
FIG. 4 is a schematic diagram illustrating another example of separation of a single-wafer object.

(First Embodiment) (FIGS. 1 and 3) A single-wafer separating apparatus 10 continuously conveys single-wafer articles 1 by a conveyer 11 and transfers the single-wafer articles 1 to the conveyer 1.
In stacking on the output-side stacking conveyor 12, a group of preceding sheet materials 1 (for example, A) and a group of succeeding sheet materials 1 (for example, B) are separated from each other.

At this time, in the single-wafer separating apparatus 10, a separating lever 13 is arranged in a transfer area from the transport conveyor 11 to the collecting conveyor 12. The separation lever 13 is in contact with the side surface of the single-wafer 1 in the process of being transferred from the transport conveyor 11 to the stacking conveyor 12, and is rotatable by a rotary actuator 14, so that the above-described abutting position on the single-wafer 1 is achieved. Can be changed in the width direction of the accumulation conveyor 12. Thus, when the separation lever 13 can be switched to, for example, the first and second pivoting positions, the sheet-like material 1 brought into contact with the separation lever 13 set at the first pivoting position is stacked. The first group A is accumulated at the first accumulation position on the upper surface 12, and is then brought into contact with the separation lever 13 set at the second pivot position by the operation of the rotary actuator 14. The single-wafer articles 1 are stacked on a stacking conveyor 12 at a second stacking position having a lateral positional relationship in the width direction of the stacking conveyor 12 to form a second group B. That is, the separation lever 13 changes the stacking position on the stacking conveyor 12 of the sheet 1 transferred from the transport conveyor 11 to the stacking conveyor 12 in the width direction of the stacking conveyor 12, and as a result, The group of the leaf 1 (for example, A) and the group of the following single leaf 1 (for example, B) can be separated from each other.

Further, in the single-wafer separating apparatus 10, the conveyor surface of the stacking conveyor 12 is lower than that of the conveyor 11 and the conveyor speed is lower. The subsequent single-wafer object 1 (12) is formed into a scale shape in which the succeeding single-wafer object 1 (12) is partially overlapped with the preceding single-wafer object 1 (11).

Therefore, the separating operation by the single-wafer separating apparatus 10 is performed as follows (FIG. 3). (1) Set the separation lever 13 to the first turning position. As a result, the preceding sheet 1 comes into contact with the separation lever 13 at the first turning position, and the first group A (for example, the sheet 1) is stacked at the first stacking position on the stacking conveyor 12. (A group formed by the sheet-like articles 1 having the numbered 100s).

(2) When switching from the first group A to the second group B, the separation lever 13 is switched to the second turning position. As a result, the succeeding sheet 1 comes into contact with the separation lever 13 at the second turning position and the second
To form a second group B (for example, a group formed by the single-wafer objects 1 having a number assigned to the 200th unit).

(3) Upon switching from the second group B to the third group C, the separation lever 13 is again set to the first turning position. As a result, the succeeding single-wafers 1 abut on the separation lever 13 at the first turning position and are collected at the first stacking position on the stacking conveyer 12, so that the third group C (for example, A group consisting of single-wafer objects 1 with the numbered 300s)
To form

Thereafter, by repeating the above (1) to (3),
Each of the groups A, B, C,... Of the single-wafer articles 1 can be separated in a staggered manner in the conveyor traveling direction of the accumulation conveyor 12.

In the single-wafer separating apparatus 10, the separating lever 13 may be pivotally moved to three or more positions. For example, when the setting of the separation lever 13 is changed to the first to third turning positions, the stacking position of the sheet 1 on the stacking conveyor 12 is changed to each of the three positions in the width direction of the stacking conveyor 12. (FIG. 4). However, the stacking positions on the stacking conveyor 12 are two positions in the width direction of the stacking conveyor 12, and when the stacking shapes are mutually staggered, the sheet-like articles 1 are stacked in multiple stages while the width direction size of the stacking conveyor 12 is reduced. Can be separated.

Therefore, according to the present embodiment, the following operations are provided. The transport conveyor 11 is used as a separating unit for separating the single-wafer articles 1 continuously transported by the transport conveyor 11 into the preceding and succeeding groups.
The stacking position on the stacking conveyor 12 of the sheet 1 transferred to the stacking conveyor 12 from the stacking conveyor 12
It suffices to prepare a device whose setting can be changed in the width direction, and the configuration can be simplified. Further, the stacking position of the single-wafer articles 1 can be separated only by changing the setting in the width direction of the stacking conveyor 12, that is, by shifting the stack horizontally, and the separation work efficiency can be improved.

The above-mentioned separating means is constituted by the separating lever 13, and the structure is simple.

By making the stacking state of the sheet-like materials 1 in a scaly shape, the number of sheets stacked per unit length of the stacking conveyor 12 can be increased. Further, when the single-wafer objects 1 of each group separated on the accumulating conveyor 12 are put together for each group, it is sufficient to bring the preceding and succeeding single-wafer objects 1 from a partially overlapping state to an all-overlying state. There is no change in the upper / lower relationship of the overlap, and there is no deviation in the preceding and following order. Therefore, the efficiency of the separation operation can be further improved.

(Second Embodiment) (FIG. 2) The sheet separating apparatus 20 of the second embodiment is different from the sheet separating apparatus 10 of the first embodiment in that a conveyor moving device 21 is provided.
Has been used. The conveyor moving device 21 allows the stacking conveyor 12 to move laterally on the exit side of the transport conveyor 11, and allows the horizontal movement position to be changed in the width direction of the stacking conveyor 12.

Thus, when the accumulation conveyor 12 can be switched to, for example, the first and second lateral movement positions, the first
Are transferred to the stacking conveyor 12 set at the horizontal movement position of the first stacking position, and are stacked at the first stacking position on the stacking conveyor 12 to form the first group A. The sheet 1 conveyed to the stacking conveyor 12 set to the second lateral movement position by the operation of the second stacker 21 has a second stacking position on the stacking conveyor 12 which is laterally shifted in the width direction of the stacking conveyor 12. Second group B accumulated at the location
Is formed. That is, the conveyor moving device 21 determines the stacking position on the stacking conveyor 12 of the sheet 1 transferred from the transport conveyor 11 to the stacking conveyor 12,
The setting is changed in the width direction of the accumulation conveyor 12, and as a result, the group of the preceding sheet material 1 (for example, A) and the group of the succeeding sheet material 1 (for example, B) can be separated from each other.

Incidentally, even in the single-wafer separating apparatus 20, the conveyor surface of the accumulating conveyor 12 is lower than that of the conveying conveyor 11, and the conveyor speed is lower.
The accumulation state of the single-wafer articles 1 is set to be a scale-like shape in which a succeeding single-wafer article 1 (12) partially overlaps the preceding single-wafer article 1 (11).

Accordingly, the separating operation by the single-wafer separating apparatus 20 is performed as follows (FIG. 3). (1) The conveyor 12 is set to the first lateral movement position by the conveyor moving device 21. As a result, the preceding sheet material 1 is accumulated at the first accumulation position on the accumulation conveyor 12 to form the first group A.

(2) When switching from the first group A to the second group B, the integrated conveyor 1 is moved by the conveyor moving device 21.
2 is set to the second lateral movement position. As a result, the succeeding single-wafer articles 1 are accumulated at the second accumulation position on the accumulation conveyor 12 to form the second group B.

(3) When switching from the second group B to the third group C, the conveyor moving device 21 moves the integrated conveyor 1
2 is again set to the first lateral movement position. As a result, the succeeding single-wafer articles 1 are accumulated at the first accumulation position on the accumulation conveyor 12 to form the third group C.

Thereafter, by repeating the above (1) to (3),
Each of the groups A, B, C,... Of the single-wafer articles 1 can be separated in a staggered manner in the conveyor traveling direction of the accumulation conveyor 12.

Incidentally, even in the single-wafer separating apparatus 20, the conveyor moving device 21 may move the accumulating conveyor 12 laterally to a plurality of three or more positions. For example, when the stacking conveyor 12 is set to the first to third lateral movement positions, the sheet 1 changes the stacking position on the stacking conveyor 12 to each of three positions in the width direction of the stacking conveyor 12. (FIG. 4).

The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration of the present invention is not limited to this embodiment, and the design can be changed without departing from the scope of the present invention. The present invention is also included in the present invention. For example, in the first embodiment, a guide member that guides a side surface of the single-wafer product 1 opposite to a side surface in contact with the separation lever 13 may be provided on the accumulation conveyor 12. The separating lever constituting the separating means is not limited to the pivot type, but may be a linear movement type. Although the separation lever is fixedly arranged at the position after the setting change until the stacking group is changed, the separating lever may reciprocate while forming one group on the stacking conveyor. Further, one of the setting positions of the separation lever may be a position where the separation lever does not abut on the sheet-like material. In this case, in the first embodiment, the sheet material 1 moves on a straight line from the transport conveyor 11 to the accumulation conveyor 12. Further, the separating means does not have to laterally move the stacking conveyor, but may move the sheet feeding conveyor to the stacking conveyor in the width direction of the stacking conveyor. Furthermore, instead of arranging the transport conveyor and the accumulation conveyor in a straight line, they are arranged in an intersecting manner, and the vicinity of a position where the sheet is to be conveyed by the accumulation conveyor by changing the direction by 90 degrees from the conveyance direction by the conveyance conveyor. May be used for separation using a separation means.
