At both ends of this elevating body (C), both lower ends of a stopper ■ having a mouth shape when viewed from the front are connected via a common pin (to). (c) and stopper (c) can be separated.

On the inner surface of the inner machine frame 01, guide bodies (7) into which both sides of the m stopper (to) fit are arranged, and these guide bodies (e) can be fixed or detachable from the machine frame (10+). (support) is a high-speed idling roller', which is disposed behind the rear surface of the operating position of the stopper.In other words, a bearing (support) that can be freely fitted into the recess α4 from above is attached to the roller. A core cylinder (7) is provided at both ends of the roller (1rIIli), and the lower surface of the core cylinder (7) can freely come into contact with the t-plane of the drive belt σθ. A pair of left and right rubber rollers 0]) are fitted and fixed on the core cylinder (toward), and these rubber rollers 3]) are distributed to the left and right while avoiding the drive belt α6, and the outer ends of each (1 frame It is brought close enough to the inner surface of Q0. Here, the core cylinder (7) is set to have a smaller diameter than the idle roller qυ, and the rubber roller zero force is set to have a larger diameter than the idle roller (6). (To) is a roller at the L position that receives the lower surface of the bZ8 belt αθ, and (7) is a roller at the lower position.

To explain the function of this conveyor (1), the storage container (2) conveyed by the conveyor surface (1) is

After the work path r, the cylinder system is contracted by a signal from the control device (9), and the stopper is lowered as shown by the solid line in FIG. 3 via the elevating body. As the stopper 2 descends, the curved surface is released (f), f: storage container (February) is conveyed in a sending shape by an idling roller Qυlζ, and then passed to a high-speed idling roller (b). The idling roller (2) receives power from the drive belt qQ via the core cylinder (7), and since the core uneven roller Oη rotates integrally with the core cylinder (7), the storage g
g9 (2) is conveyed by the rubber roller Gslζ at a higher speed than usual. Therefore, at the time of completion of delivery, there is a gap between the storage container (21) and the subsequent storage container (21) that has been conveyed in a predetermined manner, and by raising the stopper through this gap, the storage capacity of the second readout (second) is (21). ) can be reliably accepted.

In this embodiment, an empty storage container (2) is supplied to the beginning of the conveyor (1), and the example display element of the indicator (6) is 1.
The number of products to be taken from the container (t) to the storage container (2) on the conveyor (1) is displayed on the loading/unloading device.

The other configurations are the same as in the first embodiment.

As shown in FIGS. 10 and 11, the cargo bed pipe device θQ is provided with a large number of free rollers at each stage of fixed shelves θ.

Next, I will explain the sorting work. The empty transport container (2) placed at the starting end of the conveyor (1) is transported by the conveyor (υ) and detected by the detector (3).

The control device (9) controls each storage container a', ! based on the output signal of the detector (3). The current location of r(2) is calculated and stored. Then, the storage container (2) is placed at a predetermined storage position R[F]) where the product needs to be loaded into the corresponding detector (3).
), the control device (9) detects the stopper (goods) and indicator path (goods) corresponding to the storage location CB).
6) and the display device). The storage container (2) is thus stopped at a predetermined storage position. The worker (7) reads the indicator light of the display device θQ,
You can know the occurrence of work in your assigned zone, and you can also check the display (
From the indicator light □□□ in 6), it is possible to know from which cargo bed pipe device (c) the goods should be taken out. Therefore, the worker (7) goes to the indicator road (6) where the indicator light (b) is lit.
The number of products indicated by the display of finished product is taken out from the container (7) of the back body pipe device 42, and placed in the storage container (2) of the conveyor (1).And each time the feeding is completed, , press the pushbutton switch (2) on the display (6). When this pushbutton switch (6) is pressed, the display (6) is reset and the display disappears. The worker (7) After completing the work, press the reset button on the display device ■.At this time,
If there is no display u (6) in the zone that has not been reset, the control device (9) resets the indicator light of the display production date (7), and also resets the indicator light of the display date (7) and indicates that the stock t<94
lower. This causes the storage container (27) to be sent out.

For this storage container (2), data is stored in a control device (9) in the register system, and new data (
Based on this, the next storage location to work on (B)
Then, the storage container (2) is stopped, and the display device (6) and the display device (g) are operated. and workers like the above (7)
The operation is repeated at the required storage location [F]), and at the end of the conveyor (1) several products are stored in the data exchange previously entered into the control device (9) on the basis of the shipping document. The storage containers @ (2) on the shipping destination side, each containing a predetermined number of containers, are transported.The following operations are repeated for each storage container (2), and the sorting operation is performed.

In this way, since the accumulation conveyor (1) is used, the storage container B (2) is stopped only at the storage container being worked on in the 6TR direction (unless a phantom is stored, the storage container B (2) is the storage location filB that requires work). This allows the sorting work to be carried out more efficiently than the conventional method in which the conveyor is stopped at each work position to stop all storage containers. In addition, in the conventional method that uses a pulse encoder fe to determine the position of the storage container from the traveling distance of the conveyor,
Since we use λ, it is possible to always accurately stop the storage container (2) at the predetermined storage position 11 (B>I) without causing the stop position to go awry due to the storage container (2; slipping, etc.). It also improves work efficiency due to the fact that it can be done easily.

In addition, in the sorting method in the storage 1 and the second embodiment, the Ia path of the cargo bed pipe device (4) wheels and their arrangement can be mutually interchanged, and modifications of each type can be adopted. Of course it is beneficial. Accumulate conveyor (1)
The configuration lζ is not limited to the above configuration, and various types can be adopted.

As explained above, according to the present invention, an accumulation conveyor is used, which eliminates the need to stop the entire storage capacity at each working position, unlike using a conventional belt conveyor. Since there is no error in the stopping position g of the storage containers due to slippage, etc., sorting improves work efficiency.
