Description of the Related Art Conventionally, a component box in which components are accommodated by a truck is mounted on a pallet and transported at a predetermined time from an external factory. This parts box is unloaded from the truck for each pallet to the temporary parts storage. The parts boxes mounted on the pallets are transported to the automatic warehouse, and the pallets are temporarily stored in the automatic warehouse. The worker takes out the parts boxes from the automated warehouse so that the number of parts boxes on the parts shelves in the manufacturing line does not become the number of dangerous stocks, and sequentially pays out the parts boxes for each pallet. The pallet of the delivered parts box is transferred to the truck connected to the towing vehicle. Then, the operator operates the towing vehicle to pull the cart, and conveys (delivers) the component box to the production line for each pallet.

The worker supplies the parts box to the parts shelf of the manufacturing line, and returns the parts box which cannot be supplied to the parts shelf to the manufacturing line to the automatic warehouse for each pallet. Then, the parts box is temporarily stored again in the automatic warehouse for each pallet.

[0004]

However, since the number of types of parts is actually quite large, whether or not the number of parts boxes supplied to the parts shelves on the production line becomes a dangerous stock number is determined. There is a problem that it is very troublesome for the operator to manage.

Further, if the management is not sufficiently done, there is a risk that the parts boxes supplied to the parts shelves of the manufacturing line will be exhausted and the manufacturing line will be adversely affected.
Then, when the parts boxes that could not be supplied to the parts shelves on the manufacturing line were returned to the automatic warehouse and were temporarily stored in the automatic warehouse, the same parts box as this parts box was stored in the automatic warehouse for each pallet. To do. In this case, it is required to deliver the parts box delivered from the external factory and stored in the automated warehouse to the parts shelf of the production line. However, it is difficult for the worker to determine which of the parts boxes was delivered first and was stored in the automated warehouse, and there is a problem that the parts boxes sequentially delivered from the external factory cannot be supplied to the production line. is there.

The present invention has been made in order to solve the above problems, and a first object of the present invention is to prevent an operator from managing a parts box to be dispensed to a manufacturing line, and to An object of the present invention is to provide a method of managing a parts box to be dispensed to a manufacturing line that does not manage the delivery order.

A second object is, in addition to the first object, to provide a management method of parts boxes to be dispensed to a manufacturing line so that the parts boxes supplied to the parts shelf of the manufacturing line are not lost.

A third object is, in addition to the first or second object, to provide a management method of parts boxes to be dispensed to a manufacturing line, which improves the efficiency of transporting the parts boxes to be dispensed to the manufacturing line.

Set the payout time to pay out to the production line, and pay the parts boxes temporarily stored in the automated warehouse for each pallet to the production line for each pallet with the payout time set based on the payout cycle. The parts boxes of each of the parts boxes are stored in the automated warehouse, and the delivery time for delivering the parts boxes to the next production line is set based on the delivery cycle. The point is to pay out to.

According to a third aspect of the present invention, when the delivery time of a component box conveyed from an external factory is the same as the delivery time of a component box that cannot be supplied to the manufacturing line,
The point is that these parts boxes are simultaneously delivered from the automated warehouse to the production line for each pallet.

[0012]

According to the first aspect of the present invention, the component box mounted on the pallet and conveyed from the external factory is temporarily stored in the automatic warehouse. At this time, a payout time for paying out the component box to the manufacturing line is set. Then, the component boxes temporarily stored in the automated warehouse for each pallet are delivered from the automated warehouse based on the delivery time and sequentially delivered to the production line. Then, the remaining parts boxes that could not be supplied to the manufacturing line are returned to the automatic warehouse and temporarily stored. At this time, the payout time for paying out the parts box to the manufacturing line next is set. Then, the parts boxes are delivered from the automated warehouse to the production line for each pallet based on these delivery times.

Therefore, since it is sufficient for the worker to pay out the component boxes sequentially delivered from the automated warehouse to the production line, the worker does not manage the component boxes delivered to the production line. It becomes possible. Further, it becomes possible not to manage the delivery order of the component boxes delivered from the automated warehouse to the production line. Moreover, it becomes possible to supply the parts boxes stored in the automatic warehouse to the production line in order.

According to the second aspect of the present invention, the component box mounted on the pallet and conveyed from the external factory is temporarily stored in the automatic warehouse. At this time, the payout time is set on the manufacturing line based on the payout cycle in which the parts box does not reach the dangerous stock number. Then, the component boxes temporarily stored in the automated warehouse for each pallet are sequentially delivered from the automated warehouse to the production line at the delivery time set based on the delivery cycle. Further, the remaining parts boxes that cannot be supplied to the manufacturing line are returned to the automatic warehouse again and temporarily stored. At this time, a payout time for paying out to the manufacturing line next is set for this parts box based on the payout cycle. Then, the parts boxes are delivered from the automated warehouse to the production line for each pallet based on these delivery times.

Therefore, it is sufficient for the worker to pay out to the manufacturing line the parts boxes that are sequentially delivered from the automated warehouse based on time so that the parts box does not reach the dangerous stock number on the manufacturing line. It is possible to prevent the operator from managing the parts box to be put out. Further, it becomes possible not to manage the delivery order of the component boxes delivered from the automated warehouse to the production line. Further, it becomes possible to sequentially supply the parts boxes stored in the automatic warehouse to the production line. Moreover, since it is possible to manage the parts box so that the number of parts in the production line does not reach a dangerous stock number, it is possible to prevent the parts from running out of the production line.

According to the third aspect of the present invention, the delivery time of the component boxes transferred from the external factory and stored in the automatic warehouse and the delivery time of the component boxes that cannot be supplied to the manufacturing line and are stored again in the automatic warehouse. If the two match, the parts boxes are delivered from the automated warehouse to the production line at the same time, so that the parts box transportation efficiency can be improved.

The next payout time for the parts box 3 of the pallet 4 is 9:
The parts box 3 for each pallet 4 is delivered from the automatic warehouse 6 at that time.

Similarly, since the payout cycle of the parts box 3 of the pallet 4 having the tentative number B1 is 45 minutes, the controller 30 adds 45 minutes to the previous payout time of 9:15 and sets the parts payout as 10:00. It is stored in the time memory 33. Further, since the payout cycle of the component box 3 of the pallet 4 having the provisional number A2 is 55 minutes, the controller 30 adds 55 minutes to the previous payout time of 9:15 and 10:
It is stored as 10 in the component payout time memory 33. Further, since the payout cycle of the parts box 3 of the pallet 4 having the provisional number A3 is 55 minutes, the controller 30 adds 55 minutes to the previous payout time of 9:30 and stores it in the parts payout time memory 33 as 10:20. Remember.

Therefore, after 9:35, the parts box 3 mounted on the pallet 4 is temporarily numbered B as time goes by.
2, A1, B3, B1, A2, A4, A3, B4 are output from the automated warehouse 6 in this order, and the parts shelves 12 of the manufacturing line 11
Be paid out to.

Therefore, the controller 30 sequentially manages the payout time of the component boxes 3 housed in the automatic warehouse 6. As a result, the driver of the cargo handling vehicle 16 does not have to manage the parts box 3 because the unmanned guided vehicle 20 only has to pay out the parts box 3 transferred to the carriage 18 to the parts shelf 12. You can

The controller box 3 is used to take out the parts box 3.
Since 0 is managed by time, the payout order (order) of the parts box 3 is automatically set. As a result, it is possible not to manage the payout order of the component boxes 3. Even if the same parts box 3 with the temporary number A1 is stored in the automatic warehouse 6 later, the parts box 3 will be paid out after the parts box 3 of the pallet 4 with the temporary number A1 disappears. Is. As a result, an appropriate parts box 3 can be delivered from the automatic warehouse 6 to the parts shelf 12.

In this embodiment, the carrier and the number of flights to be entered are input to the input device 26. However, the product numbers corresponding to the order in which the parts boxes 3 are transferred to the storage tray 10 are input to the input device 26. Good. In this case, it is not necessary to read what kind of component box 3 the controller 30 has conveyed by the product number data memory 31. As a result, the payout time corresponding to the product number input from the payout time data memory 32 can be read. Moreover, the type of the component box 3 conveyed by the trucks 2a and 2b can be surely grasped.

Further, the input device 26 is provided with a bar code reader so that the bar codes of the kanbans of the parts boxes 3 sequentially transferred from the temporary storage place 5 to the warehousing table 10 can be read, or the bar code of the print paper can be read. It is also possible to make it read. As a result, the driver can save the trouble of operating the input device 26 to input various information.

Further, the payout cycle of the parts box 3 is set as follows, for example. For example, the maximum number of parts boxes 3 that can be supplied to the parts shelf 12 is eight, and the number of dangerous stocks of the parts box 3 is two. In this case, there are 2 parts boxes 3 with a maximum of 8 boxes.
The consumption time until it becomes a box is measured, and the transportation time for transporting the parts box 3 from the cargo handling station 15 to the corresponding parts shelf 12 is measured. The sum of the consumption time and the transportation time is the payout period for paying out the parts box 3. According to this configuration, it is possible to prevent the component box 3 from being lost on the component shelf 12 in the manufacturing line 11.

Next, technical ideas other than the claims, which are understood from the above embodiment, will be described below together with their effects.
