In the devices described in JP-A No. 186803, JP-A No. 59-217503, and JP-A No. 59-217506, the overall efficiency of the picking operation deteriorates due to variations in the amount of picking in each zone. Picking ability is often not available. That is, even if the picking work is completed in the upstream zone, if the picking work is not completed in the downstream zone, the workers in the upstream zone will have to wait. In addition, because it is not possible to accurately determine the number of workers required to obtain the desired picking capacity, it is possible to deploy more workers than necessary, or conversely, due to a shortage of workers, the number of workers required to obtain the desired picking capacity may not be determined accurately. Sometimes the picking work is not completed.

Therefore, the purpose of the present invention is to be able to average the workload for each zone when taking out articles from the storage equipment that stores them and storing the taken out articles in storage boxes, and to reduce the number of workers required. An object of the present invention is to provide an article handling device that can easily determine the number of people in a group.

[Means for solving problems]

The present invention provides an article storage facility in which an article retrieval surface is formed on one side of stored articles divided into multiple stages and rows for storing articles, and the retrieval surface is divided into a plurality of zones; A transport device disposed along the take-out surface that transports a storage box that stores the articles taken out from the take-out surface, and is controlled by a control device equipped with a timer, and picks and picks in the zone. The above object has been achieved by providing an article handling device characterized by being equipped with a workload warning device that is activated when a storage operation takes longer than a certain amount of time.

The above-mentioned picking and storage work refers to a series of operations from picking the item from the take-out surface of the storage equipment to storing the item in the storage box, and also includes cases where the item is temporarily placed in the middle. Furthermore, in the specification, picking work mainly means the work of taking out articles from containers stored in storage equipment, and storing work mainly means the work of storing the picked up articles in storage boxes on the transport device.

In addition, as shown in FIGS. 2 and 3, the storage facility A is equipped with a take-out indicator 16 located at an easily visible position on the front side of each frontage surface of the storage section 1.
is arranged, and this pick-up indicator 16 is arranged for each of the above-mentioned zones α, β, and γ, and more specifically for each frontage of the storage section 1. It is equipped with a display 161 that displays the number of articles to be taken out based on a command, and a completion button 162 that clears the display. In addition, each take-out indicator 16 is equipped with a take-out indicator lamp 163, which is activated when there is a picking command, that is, when it is necessary to take out the article in the container G from the take-out surface 13. The removal indicator lamp 163 is made to blink to notify the operator. still,
The display 161 or completion button 162 indicates each zone α,
It may be integrated into one piece or one place for each β and γ.

Further, the conveyance device B is disposed along the take-out surface 13 of the storage facility A, and is used for picking and storing the articles stored in the containers G taken out from the take-out surface 13 of the storage facility A. It is designed to transport a storage box H. More specifically, as shown in FIG. 2, the conveyance device B carries the plurality of storage boxes H independently of each other so that it can convey or stop the plurality of storage boxes H corresponding to each of the zones α, β, and γ. Three possible belt conveyors 2a, 2b, 2c are connected in series. That is, the three belt conveyors 2a, 2b, 2c are located in zones α, 2c, respectively.
They are located corresponding to β and γ, and each zone α,
A plurality of storage boxes (three in the case of the embodiment) H that fit within the length of these belt conveyors 2a, 2b, 2c provided correspondingly to β and γ are defined as a transport unit (group), and the transport Each unit is transported and stopped independently. A detector 21 (the detector for the belt conveyor 2c is not shown) is attached to the discharge side of each belt conveyor 2a, 2b, 2c to detect the leading end of the conveyance unit. Belt conveyor 2a, 2b, 2c
When a picking command (command for storing articles in storage box H) is received from the control device, the detector 21 attached thereto detects the head of the conveyance unit on the belt conveyor. If there is no picking command or picking is completed, the conveyance unit is stopped, and if there is no picking command or picking is completed, the conveyance is continued or started and the conveyance unit is carried out to the downstream conveyor, so that all the conveyance units are It stops after being carried out to the conveyor and the detector 21 enters the light-receiving state, but
If the next transport unit is being received from the upstream conveyor at the same time, the detector 21 detects the leading part of the next transport unit (however, this applies when a picking command is issued; if there is no picking command, the transport unit is It is controlled so that it stops after all items have been unloaded. For example, to summarize the control mode for the belt conveyor 2b, the conditions for starting or continuing conveyance are that the upstream belt conveyor 2a is in the starting state, or that the picking for the belt conveyor 2b is completed and the downstream side The belt conveyor 2c of
is currently being picked.

Further, as shown in the third diagram, the conveyance device B is arranged with its conveyance surface inclined toward the take-out surface 13 side, and by inclining the conveyance surface in this way, the conveyance device B The transport device B facilitates the storage (insertion) of articles into the upper storage box H, and allows the stored items to lean against the inner wall of the storage box H.
This is to prevent the load from collapsing due to acceleration and deceleration associated with starting and stopping. Further, 22 is a drive motor for the belt conveyor constituting the conveying device B, and 23
is a guide wheel that guides the storage box H.
Note that the conveying device B does not consist of the three belt conveyors 2a, 2b, and 2c as described above, but instead has three belt conveyors 2a, 2b, and 2c.
It may be constructed with a single roller conveyor extending over β and γ, and a stopper may be provided for each zone α, β, and γ, and the stopper may be controlled on/off. or,
The conveying surface of the conveying device B may be made horizontal.

In addition, in Figures 2 and 3, 24, 2
4' is a storage display, which displays each zone α,
The plurality of storage boxes H that stop corresponding to β and γ
It displays which of the storage boxes H should store the article, and 3 are displayed near the stop position of each storage box H along the transport device B, corresponding to each zone α, β, and γ. They are arranged individually. More specifically, in this embodiment, the three storage indicators 24 in each zone α, β, and γ are configured as illuminated push buttons that also function as completion buttons. Further, the storage display 24' is an auxiliary display for making storage instructions clearer, and is composed of an illumination lamp.

Reference numeral 26 denotes a temporary storage section (temporary storage table) on which articles are temporarily placed, and before the storage box H arrives at each zone α, β, and γ, the container G is
Two locations are provided in each of the zones α, β, and γ along the transport device B to temporarily store the items when they are taken out in advance.

Reference numeral 25 denotes a temporary storage display, which in the case of the embodiment is provided corresponding to each temporary storage section 26. Each temporary storage display 25 indicates in advance that an article should be taken out, and also indicates which temporary storage section 26. It is equipped with a pre-emption indicator 251 that displays whether the article should be temporarily stored in the storage section 26, and a loading indicator 252 that displays that the article that has been taken out in advance and temporarily placed should be stored in the storage box H. The pre-order indicator 251 is made up of an illuminated push button that also functions as a completion button, and the input indicator 252 is made of an illuminated lamp.

Then, one of the storage indicators 24, 24' and the indicator 251 lights up in response to the blinking of the eject indicator lamp 163 of the eject indicator 16 in the corresponding zone, and from the eject surface 13. Displays whether the retrieved article will be stored or temporarily stored in one of the three storage boxes H or in one of the two temporary storage sections 26. At the same time, when all the articles have been picked for the corresponding storage box H or the corresponding temporary storage section 26 in the corresponding zone, the corresponding storage display 24
Or, by pressing the preemption display 251, the lighting will be cleared and the next storage box H in the corresponding zone will be displayed.
is designed to prepare for picking other temporarily stored articles 26, and even if it is pressed before all the articles in the corresponding zone have been picked by mistake (if any of the pick-up indicator lamps 163 in the corresponding zone flash) ), storage indicator 24
Alternatively, the preemption indicator 251 continues to be lit to continue displaying the storage box H in which the article is to be stored or the temporary storage section 26 in which the article is to be temporarily placed.
Note that the storage display 24 or the pre-emption display 251 may not be provided with such a completion button function, but may be provided with a separate completion button for clearing the display as in the case of the ejection display 16. In that case, the completion buttons may be integrated into one location for each zone. Further, the take-out indicator 16 does not need to include the take-out indicator lamp 163, and in that case, the display 161 may be blinked, or the pick-up indicator 161 may not be blinking and picking may be performed based on the presence or absence of the number display. You may do so.

In addition, a storage box H is provided on the transport unit forming conveyor C.
As shown in FIG.
The cutting detector 42 detects that there is a storage box H to be cut out, and the cutting stopper 41
By lowering the storage box H, the storage box H is accelerated and transported one by one to the carry-in end of the transport unit forming conveyor C.

The transport unit forming conveyor C, which transports the storage boxes H to the transport device B as a transport unit as described above, is mainly constituted by a roller conveyor, as shown in FIG. A direction changer 31, a storage box detector 32, and a storage box passage detector 33 are provided in between, and a conveyance unit that detects the tip of the formed conveyance unit is provided at the output end. A detector 34 and a cutting device stopper 35 for cutting out the conveying unit onto the conveying device B are provided, and the cutting device stopper 35 is controlled as follows, and also controls the cutting conveyor D. That is, the storage box H cut out from the cutting conveyor D is transferred to the direction changer 31, and when the storage box detector 32 detects this, the direction changer 31 descends, and by this descent. The storage box H is conveyed to the unloading side by rollers, and when the storage box H passes the storage box passage detector 33, the direction changer 31 is raised to prepare for cutting out the next storage box H. The storage box passage detector 33 causes the cutting conveyor D to stop cutting out when three storage boxes H have passed. The three storage boxes H that have passed through the storage box passage detector 33 form a transport unit with the leading storage box H in contact with the cut-out stopper 35, and when there is a picking command and the transport device B When the belt conveyor 2a corresponding to the first zone α is activated, the conveyance unit is transported to the belt conveyor 2a. The cut-out stopper 35 is raised when the transport unit passes the transport unit detector 34, and prepares for forming the next transport unit.

In the case of the embodiment, the above transport unit is composed of three storage boxes H as described above, but the size of the zone, the size of the storage box H, and the size of the articles to be stored in the storage box H are different. Various selections can be made within the range of the number of storage boxes H that can fit into the zone, taking into consideration the size, number, etc. Also, multiple storage boxes H for one delivery destination.
When allocating, for example, the third
It is also possible to allocate the first storage box H and the first storage box H of the next transportation unit.

Further, the container carry-in conveyor F provided at the rear of the storage facility A is located outside the running surface of the stacker crane E, and is arranged approximately horizontally at a height near the frontage of the center stage of the storage facility A. It has been set up. and,
The container carrying-in conveyor F is configured to be able to rotate forward and reverse as appropriate, and the storage line F
Containers G, G, . . . supplied from -1, F-2, F-3 through appropriate gates (not shown) can be carried into appropriate positions.

In this embodiment, workload warning devices shown at 51 and 52 in FIGS. 2 and 3 are installed at predetermined positions, and this workload warning device allows the desired picking capacity to be obtained for each zone. It is controlled by a control device equipped with a timer. In this embodiment, (workload warning) display lamps are used as a specific example of the workload warning devices 51 and 52, and one workload warning device 51 is provided for each zone α, β, and γ. (Zone γ is not shown). Further, the workload warning device 52 includes three display lamps 52α, 52β, and 52γ that display the workload of each zone α, β, and γ.
52γ are all installed in one place.

Next, a picking mode carried out using the article handling apparatus of the embodiment having the above-described structure will be explained based on FIGS. 1 to 4.

On the free conveyor 11 of the storage facility A, the plurality of containers G that have been stored are placed in a state where the frontmost container G is in contact with the stopper 14 because the free conveyor 11 is disposed downward at the front. It is front packed.

Therefore, when a picking command is issued for zone α, the belt conveyor 2 corresponding to zone α
At the same time as the belt conveyor 2a is started, a conveyance unit consisting of three storage boxes H is cut out from the conveyance unit forming conveyor C as described above, and when the detector 21 detects the leading end of the conveyance unit, the belt conveyor 2a is stopped. The transport unit stops corresponding to zone α. At this point in time, as described above, the display 161 of the take-out display 16 provided on each front side of the storage facility A displays the number of articles to be taken out from the corresponding front side based on a command from the control device. In addition, the extraction indicator lamp 163 on the corresponding frontage in zone α is blinking based on the command from the control device, and one of the three storage indicators 24 in zone α (the It is preferable to do it sequentially starting from the side storage box H)
lights up based on commands from the control device. Therefore,
The worker should check the ejection indicator lamp 16 which is blinking sequentially.
3, the number of items indicated on the display 161 is removed from the removal surface 13 of the storage facility A, and the completion button 162 is pressed, and the storage display 24, which is lit,
24', and store it in the storage box H corresponding to the storage box H.
By pressing the storage indicator (in the case of the embodiment, an illuminated push button) 24 when the picking is completed for all the other storage indicators 2 in the zone α.
4, 24' lights up and the take-out indicator 16 lights up, so the take-out indicator 16 and the storage indicator 24,
The operator may continue the picking operation as described above in accordance with the instruction 24'.

The above-mentioned picking of the articles stored inside the container G is performed by taking out the container G at the forefront onto the container receiving stand 12. The container G is taken out to the container receiving stand 12 by a cutting device 9.

After all the picking in zone α is completed as described above, the belt conveyor 2a is activated by pressing the storage display 24, and at the same time, the belt conveyor 2b is also activated to convey the three storage boxes H. The unit is transported to zone β.
Further, by pressing the storage display 24, a display for the next picking is displayed on the takeout display 16 in the zone α.

If a picking command is also issued in zone β, a picking display for one of the temporary storage units 26 is displayed in zone β simultaneously with a picking display for storage box H in zone α.

That is, the display 161 of the take-out display 16 provided on each frontage surface of zone β displays the number of articles to be taken out from the corresponding frontage surface based on the command from the control device, and the number of articles to be taken out from the corresponding frontage surface in zone β The ejection display lamp 163 on the frontage side is blinking based on a command from the control device, and one of the two pre-emption indicators 251 in zone β (from the one for the temporary storage stand 26 on the front side of the transport unit) (preferably sequentially) are turned on based on commands from the control device. Therefore, the worker takes out the number of items corresponding to the sequentially flashing removal indicator lamps 163 from the removal surface 13 of the storage facility A in the number displayed on the display 161, presses the completion button 162, and
The retrieved article is temporarily placed in the temporary storage article 26 corresponding to the lit pre-pick indicator 251, and when all the picking for the temporary storage section 26 is completed, the pre-pick indicator (in the case of the embodiment, an illuminated push button) By pressing 251, another pre-emption indicator 25 in zone β
1 lights up and the pick-up indicator 16 also lights up, so the worker only has to continue the above-mentioned picking operation in accordance with the instructions from the pick-up indicator 16 and the preemption indicator 251.

In the case of the embodiment, since the temporary storage portions 26 are provided at two locations for each zone α, β, and γ,
It is possible to pick up items in advance for up to two storage boxes H, but if a storage box H has arrived at the corresponding zone, the items are stored directly in the storage box H without being temporarily stored. controlled by a control device.

For example, if a transport unit including a storage box H in which the item is to be stored arrives at zone β while an item is being preemptively picked from the temporary storage section 26 at the front side of the transport unit, then By performing advance picking on the temporary storage section 26 on the side and pressing the advance picking indicator 251 when the advance picking is completed, the temporary storage section 2 on the leading side of the conveyance unit is
The input indicator 252 corresponding to No. 6 lights up, and the storage indicators 24 and 24' corresponding to the storage box H in which the pre-picked item is to be stored also light up, so the pre-picked item is placed in the corresponding storage box. All you have to do is store it in the box H. If you press the storage indicator 24 after storing it, the other storage indicators 24, 24' in zone β will light up and the takeout indicator 16 will light up, so you can move to the next storage box H. , the storage indicator 24,
You can store it according to the instructions at 24'.

In addition, if the arrival of the storage box H is delayed and the pre-picking of the two temporary storage sections 26 is completed before the arrival of the storage box H, all temporarily stored items will be removed after the storage box H arrives. After the item is stored in each desired storage box H and the corresponding storage indicator 24 is pressed, the take-out indicator 16 lights up to indicate picking of the next storage box H.

Note that the same applies when a picking command is issued for zone γ. Also, in different zones,
It goes without saying that articles of the same type may be stored in different storage boxes H.

Furthermore, if there is no picking command for zone α, no picking is performed in zone α as described above, and the transport unit is transported past zone α to zone β. If there is no picking command in zone β, the transport unit is transported to zone γ, and if there is no picking command in zone γ, the transport unit is transported to the next process.

Furthermore, if transport units are assigned to each zone α, β, γ and picking is performed in each zone α, β, γ, even if the transport unit of the zone has not been completely delivered to the downstream side. When the transport unit in the downstream zone starts to move, the transport unit that has finished picking in the upstream zone is transported to the downstream zone.

In addition, picking and
If the storage work takes more than a certain amount of time, the built-in timer will operate and the workload warning device 5 will be activated.
The indicator lamps 1 and 52 light up. That is, as shown in the operation flow shown in Fig. 4, there is a picking command in the corresponding zone, and the storage box H starts from the previous zone (in this case, the picked items are directly stored in the storage box H). control) and the timer starts. If the picking operation for all the storage boxes H that have arrived at the corresponding zone and/or the storage box operation for the picked items into the storage boxes H is set on a timer (this time can be set arbitrarily using a digital switch), If the storage indicator 24 is not pressed after completing the task within the specified time (possible), the workload warning indicator lamp will light up. Therefore, if the workload warning indicator lamp in a certain zone lights up, for example, if the indicator lamp in the downstream zone lights up, the efficiency of the entire picking operation will decrease, so workers in the upstream zone It is preferable that the person assists with the picking work in the downstream zone.
In addition, the efficiency of picking in the downstream zone is high,
When the indicator lamp in the upstream zone is lit, the conveyance unit that has completed picking is carried out and there is no conveyance unit to be picked in the downstream zone, which also reduces the efficiency of the entire picking operation. Therefore, it is preferable that the workers in the downstream zone go to help with the picking work in the upstream zone.

Furthermore, if the workload warning display lamps of all zones are lit, it can be determined that there is a shortage of workers.

The timer setting time can be set to 1 hour, for example.
If you want to process 600 storage boxes H, set it to 18 seconds, and if you want to process 300 storage boxes H in one hour, set it to 36 seconds. Also, as mentioned above,
The workload warning device 51 installed in each zone is useful in determining whether a worker should go to help with picking work in another zone. or,
Indicator lamps 52α, 52β installed in one place,
The workload warning device 52 consisting of 52.gamma. is useful for a manager to determine whether there is a shortage of workers. After the workload warning display lamp lights up, when the user performs picking and storage work and presses the storage display 24, the timer is reset and the workload warning display lamp goes out.

The embodiments of the article handling device of the present invention have been described above, but the present invention is not limited to these. For example, when there are a large number of zones, even if the workload warning indicator lamps of all zones are not lit, There are times when it can be determined that there is a shortage of workers. Further, as the workload warning device, an appropriate warning means such as a buzzer may be used instead of the workload warning display lamp. Further, the article handling device of the present invention does not necessarily need to be provided with the temporary display device 25 and the temporary storage section 26.
