There are things that are used to store and retrieve stored items.

However, since this transfer device inputs and unloads stored items one by one, while one stored item is being loaded and unloaded, other stored items must be kept in a standby state, and the loading and unloading time is limited. There is a problem that the wallet time is long, for example, 15 seconds, and it takes time to enter and exit the warehouse.

Another example of a horizontal rotating shelf transfer device is one that includes a plurality of tables and moves them in circulation along a horizontal rotating shelf, like a Ferris wheel at an amusement park, to enter and exit a warehouse.

However, even with this transfer device, the table is moved to a predetermined shelf position and then stopped to take in and take out the stored items, so other stored items or empty tables are in a state of being idle. There is also the problem that it takes time to enter and exit the warehouse.

Still another example of a transfer device for a horizontal rotating shelf is one described in Japanese Utility Model Application Laid-Open No. 62-83006. This transfer device transfers loads between a pair of left and right conveyors that have a load receiving device on the front side of a load storage device corresponding to a horizontal rotating shelf, and a load receiving device provided at the lowest stage of the load storage device. It has a transfer device and a load transfer device that transfers the load between the transfer device and a working section located above the lowermost stage.

However, with this device, even if the cargo receiver moves to the desired height of the shelf of the cargo storage device, the cargo cannot be delivered while the shelf is rotating, and the cargo receiver must be kept in a standby state. After all, there is a problem in that it takes time to enter and exit the warehouse.

In order to store the stored items in this configuration, first, the storage lifter circulates and moves the support elevating means on which the stored items are placed to the stage of the shelf where the stored items are stored. Next, the storage conveyor corresponding to this shelf stage receives the stored items from the stopped support elevating means and conveys them to the stored items storage position. Finally, the storing of the stored items is completed by pushing the stored items from the storage conveyor to a desired shelf using the storage pusher.

While the storage conveyor is transporting the stored items, the warehousing lifter places the next stored item on the support elevating means and moves in circulation to move the stored item to the storage conveyor or another storage conveyor.

Therefore, the stored items are stored in the carousel by being branched and conveyed from one storage lifter to a plurality of storage conveyors.

Second, the present invention provides a warehousing lift that circulates vertically along the horizontal rotating shelf and includes a plurality of support elevating means corresponding to the steps of the pillars of the horizontal rotating shelf consisting of multiple shelves that circulate horizontally. a plurality of storage conveyors provided along the various stages and transporting the stored items from the supporting lifting means to the receiving storage position; and a plurality of storage conveyors provided corresponding to the various stages above the storage conveyors.

It may also be a mechanical system that controls the speed of elevation.

Furthermore, the center angle of the striker and the mounting position of the sensor are not limited to the above embodiments.

Next, the warehousing operation of stored items will be explained.

The stored items W are sent to the orthogonal transer 13 by the warehousing conveyor 12, passing in front of the barcode reader 36. The barcode reader 36 reads the barcode (not shown) written on the side of the stored item W, and reads the barcode (not shown) written on the side of the stored item W. 11, a signal is sent to the device specifying the number of shelves 30 in which the stored items W are stored and the tray 31 on that shelf.

Here, if the stored items W are brought in continuously by the warehousing conveyor 13, the double stomper 37 is activated and the next storage item W on the orthogonal transer 13 is sent to the warehousing lifter 14. The object W is kept in a standby state to prevent stored objects from colliding with each other.

The stored object W on the orthogonal transer 13 is moved between the rollers 35 by a pair of belts 41 and 41 protruding from between the rollers 35.
It is then raised slightly and fed onto the pair of belts 41, 41 of the storage lifter 14. Therefore, the conveyance direction of the conveyed object W has been changed by 90 degrees.

Based on the control signal of the interference area escape signal generator 102, the seat 4
5.45 and stopped by a stopper (not shown). The pair of belts 4545 is also stopped by a stored object detection sensor (not shown).

The stopped stored items W are scooped up from both sides by a pair of support elevating means 47, 47 that circulate in the vertical direction and are conveyed upward.

When the storage lifter 14 lifts the stored items W to near the position of the designated shelf 30 read by the barcode reader 36, the lifting speed is slowed down by the control signal from the support elevating means speed change signal generator 100.

Then, the air cylinder 50 of the warehousing pusher 52 is actuated by the control signal from the warehousing pusher activation signal generating section 101, and the pusher 51 pushes the side surface of the stored item W, and moves the stored item W from the supporting elevating means 47 to the storage conveyor 1.
Push out to 5.

Note that when storing the stored item W on the lowest shelf, the stopper and the stored item detection sensor become inactive by reading the bar code reader 36, and the pair of health) 45
．． 45 continues to rotate without stopping, and the stored items W are sent to the storage conveyor 15 at the lowest stage before being scooped up by the support elevating means 47.

Thereafter, the warehousing lifter 14 immediately moves to the next operation to convey the next stored item to the storage conveyor or another storage conveyor.

, the storage conveyor 15 conveys the stored items W to the storage item storage position 30a of the shelf 30.

On the other hand, the multi-stage carousel moves the specified tray 31 to the storage item storage position 30a while the storage item W passes through the barcode reader 36 and is sent to the storage storage position 30a. It is on standby.

The stored items W are pushed from the storage conveyor 15 by the cylinder 60 of the storage pusher 16 into the tray 31 waiting at the stored item storage position 30a.

This means that the stored items are automatically stored in the desired shelf.

Even if the stored items W on the storage conveyor 15 are sent to the stored item storage position 30a, the designated tray 31 is still
When the stored item W has not been sent to the stored item storage position 30a, the stored item W is in a waiting state, and the stored item W to be sent after that is also in a waiting state on the storage conveyor 15.

Next, the operation of unloading the stored items W will be explained.

A control device (not shown) moves the tray 31 on which the stored items W to be delivered are placed to the stored item unloading position 30c,
The cylinder 65 of the delivery pusher 17 is activated. Then, the pusher 67 moves while being guided by the guide 66, and the stored items W are pushed onto the support elevating means 72, 72 of the delivery lifter 18, which is stopped facing each of the 30 stages. Thereafter, the stored items W are lowered by the delivery lifter 18 and placed on the pair of belts 73, 73. Finally, it is transferred from the pair of belts 73 onto the delivery conveyor 19 and is delivered by the delivery conveyor 19.

In addition, although each shelf of the multi-stage rotating shelf 11 in the above embodiment is designed to rotate individually, a multi-stage rotating system in which the shelves are arranged vertically into blocks and all the rails rotate together is possible. It may also be a shelf.

According to the multistage carousel transfer device 10 of the above embodiment,
When storing the stored items W, the storage lifter 1 with one stored item W is used.
4 to a plurality of storage conveyors 15 for conveyance, the warehousing lifter 14 is transferred to a plurality of storage conveyors 15.
After sending the stored item W into the container, it is possible to immediately move on to the operation of carrying in the next stored item. Therefore, the storage lifter 14 can operate to store the next stored item, and even if one stored item W is not completely stored, the next stored item W can be stored.

Furthermore, when the stored items W are transported to the storage position, if the designated tray 31 has not yet moved, the stored items W can be kept in a waiting state on the storage conveyor 15, and then Even if the stored items W are subsequently sent onto the storage conveyor 15 one after another, the stored items W can also be kept in a standby state, and the storage lifter 1
It does not cause the same problem to the warehousing operation in step 4.

In addition, since the support elevating means 47 is continuously operated without stopping, the transfer operation can be performed with high efficiency.

In this way, since the stored items W can be stored one after another at regular time intervals, the storage time required for storage is shortened.

In addition, since the unloading lifter 18 directly receives the stored items W to be unloaded from various sources, unloading time is shortened, and in combination with the above-mentioned unloading lifter storage conveyor, loading and unloading can be performed at the same time, further reducing the time required for loading and unloading the stored items. Can be shortened.

Effects of the Invention As described above, according to the horizontal rotary transfer device of the present invention, the storage lifter and the storage conveyor are used to store the stored items. After feeding, you can move on to the next storage item storage operation, and furthermore, even if the specified position of the shelf is not in time for storage of the storage item and the storage item is not at the storage item storage position, it will be possible to move on to the storage conveyor. Since the stored items can be kept in a standby state and the next stored item can be stored using the warehousing lifter, the warehousing time is shortened.

Furthermore, according to the configuration including a delivery lifter and a delivery pusher, it is possible to enter and take out the warehouse at the same time, and the time required for entry and exit can be shortened.
