Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pending work display device, and particularly to a device for displaying pending work stored in a storage.

[Prior Art] In each manufacturing process of vehicles that are carried out in a factory, multiple vehicles of different types are often manufactured on the same line. do not have,
The number of types of vehicles manufactured on the same line is also increasing.

Generally, a vehicle manufacturing process consists of a plurality of manufacturing lines, such as a painting line and an assembly line. In order to properly manage the production progress of the equipment and work that goes into each of these lines and improve overall work efficiency, it is necessary to rearrange the transport order of vehicles each time to optimally match each line. It becomes necessary to do something.

In particular, on the vehicle assembly line, it is necessary to send vehicles with high and low assembly difficulty at appropriate frequencies, and if there are vehicles with specifications that require specific parts to be assembled, those vehicles with the specifications will be used to increase the supply of parts. It is also necessary to send it at an appropriate frequency.

FIG. 4 shows an example of a storage for rearranging the transport order provided between a vehicle painting line and an assembly line.

This storage 10 includes multiple first-in, first-out lanes 1
2, and vehicles sent from the painting line are stored at one end in each lane 12. And each stored vehicle is
One vehicle is generally taken out from each lane 12 and supplied to the assembly line in a desired vehicle transport order.

In this way, the vehicles supplied from the painting line are rearranged into the optimal transport order and then supplied to the assembly line.

By the way, on the vehicle manufacturing line, parts are not supplied as planned due to equipment failures, work errors, or delayed delivery of parts at the parts manufacturing factory, resulting in parts shortages where the parts inventory on the assembly line is zero. may occur.

In such a case, the assembly site immediately contacts the control room, and based on this communication, the missing part number is input from the input device in the control room. At the entrance of the assembly line, measures are taken to ensure that missing parts are assembled (=J) and vehicles do not flow onto the assembly line.

That is, vehicles flowing through a series of production lines are attached with vehicle cards on which various data are written.

When the vehicle is removed from the storage 10, the worker inserts the vehicle card into the card reading device 14 before putting the vehicle into the assembly line.

As a result, for the assembly of the vehicle, a parts instruction flyer is printed out from the printer, and the worker attaches this flyer to the vehicle and then inserts it into the assembly line.

However, if the vehicle is a specification vehicle in which the part inputted as the missing part number is assembled, the instruction leaflet will not be issued even if the vehicle card is read. Instead, the hold lamp lights up and a warning buzzer sounds, instructing the driver to put the vehicle on hold.

In the prior art, by placing a vehicle card on a card reading device in this way, an operator can know whether the vehicle in question is a reserved vehicle or not.

Then, the worker stores the reserved vehicles in the reserved line 16 so that they do not flow to the assembly line.

Further, if such a parts availability period continues for a long time, the reservation line 16 may become full with reserved vehicles. In such a case, the worker stores the parked vehicle in the spill area 18 for storing defective vehicles.

[Problems to be Solved by the Invention] According to the prior art as described above, there are the following problems.

Whether or not the vehicle stored in the storage 10 is a reserved vehicle with missing parts cannot be known until the vehicle card of the vehicle is inserted into the card reader 14.

Therefore, there was a problem in that the vehicles taken out from the storage 10 could not be quickly sorted into reserved vehicles and non-reserved vehicles, and the work of storing vehicles in the retention line 16 could not be carried out efficiently. .

In particular, when the holding line 16 is full, the held vehicles must be returned from the entrance of the assembly line where the card reader 14 is located to the unloading area 18 located upstream of the line. First, there was a problem in that this was a major cause of a decrease in work efficiency.

In addition, in such conventional technology, when a part shortage condition is resolved, the control room inputs the cancellation data for the corresponding shortage part number, and at the same time, the field is notified by telephone.

However, if several types of parts are out of stock and only some of the parts are out of stock, there will be a mix of vehicles on hold and vehicles whose hold has been cleared, and the vehicle card will eventually be canceled. There is a problem in that unless the card reader 14 is pressed, it is not possible to confirm whether the held vehicle is a held vehicle or not.

Purpose of the Invention The present invention has been made in view of such conventional problems, and its purpose is to accurately display pending workpieces stored in storage and to display workpieces to be carried out from storage to the next process. An object of the present invention is to provide a pending work display device that enables quick sorting of pending work and non-suspended work.

[Means for Solving the Problems] In order to achieve the above object, the present invention stores workpieces by 11 people in a storage having a plurality of first-in, first-out lanes, and stores workpieces that are generally taken out from the storage in a state where parts are missing. In a device that sorts the held work and other non-held work, and carries out the held work to a predetermined holding area and the non-held work to the next process, the work is arranged in advance in each lane of storage. a first input means for inputting data as an initial condition; a work detection means for detecting the workpieces being carried in and out of each lane of the storage area; a first calculation means for calculating the arrangement of the workpieces stored in each lane, a first storage means for storing the calculated arrangement data of the workpieces, and a second input means for inputting data on missing parts. and a second storage means for storing the inputted missing part data, and based on the inputted missing parts data, calculates and calculates the storage position of a reserved work that uses the part from the workpiece arrangement data. The present invention is characterized by comprising: a second calculation means; and a display means for displaying the calculated storage position of the pending workpiece.

(Function) With the above configuration, before the work is carried out from the storage 1 to the storage, the worker can surely recognize whether or not the work is a suspended work with parts missing. .

Therefore, as soon as a work is taken out from the storage, the operator can quickly sort the work to determine whether it is a held work or a non-held work, and supply the held work to a holding lane, for example, and the non-held work to the next process. becomes possible.

In addition, when the holding lane is full, the held workpieces taken out from the storage can be stored directly in the dumping area, further improving work efficiency compared to conventional equipment. becomes possible.

[Example] Next, a preferred example of the present invention will be described based on the drawings. Note that the same reference numerals are given to the members corresponding to those in FIG. 4, and the explanation thereof will be omitted.

FIG. 1 shows a block diagram of a preferred embodiment of the invention.

In the embodiment, a vehicle type identification device 2o is disposed on the entrance side of the storage 1o, that is, on the side of the painting line 20.
Then, the identification number of the vehicle that has arrived at the storage 1o is read, and the specifications of the vehicle are determined by inquiring the host computer 22 about the read identification number.

Next, the arithmetic unit 24 connected to the host computer 22 determines the loading lane 12 (5 lanes in the example) for the arriving vehicle based on a predetermined algorithm, and loads the vehicle into the lane 12. .

In addition, limit switches 26 and 28 are provided at the entrances and exits of the lanes 1 to 10, respectively.
Detects the loading and unloading of vehicles into and out of 2.

Further, the pipe control 00 of the manufacturing line is provided with a work arrangement setting device 30 and a pending work setting device 32.

The work arrangement setting device 30 inputs, as an initial condition, the arrangement of vehicles stored in advance in each lane 12) of the storage line 16 and the splash field 18 of the storage 10.

In addition to this, there is also a holding line 16 and a splash area 18.
It is also used to set the transport and general use position each time a vehicle is brought into the interior.

Based on the data input from the work arrangement setting device 30, the detection data input from the vehicle type identification device 20° limit switch 26, 28, etc., the arithmetic device 24 calculates
Storage 10. It operates as a first calculation means that calculates the arrangement of vehicles within the holding line 16 and the splash field 18 in real time. The vehicle arrangement data calculated in this way is written and stored in the arrangement storage device 34 each time.

Therefore, stored in this sequence storage device 34 = 1
1 - Vehicle line data is stored in storage 10. Hold line 16
The data is sequentially updated with new data each time a vehicle is carried in and out of the splash area 18.

The vehicle arrangement data calculated in this manner is displayed as an image for the operator using the CRT 36.

FIG. 2 shows an example of the display screen of the CRT 36, and the operator can use this screen to appropriately select the vehicles to be input so that the transport order of the vehicles on the assembly line will be the optimal combination. .

In addition, in the apparatus of the embodiment, when a part shortage condition occurs on the assembly line, the control room 100 is notified from the work site, and the pending work setting device 32 provided in the control room 100 is notified.
, the part number that is out of stock is input. Similarly, when there is a notification from the work site that the parts shortage condition has been resolved, the pending work setting device 32 inputs the cancellation data for the corresponding part number. And part number storage device 3
8 stores all part numbers that are currently out of stock based on such input data.

In addition, the arithmetic unit 24 uses an algorithm (to be described later) (
The second step is to search for the storage location of the parked vehicle based on Fig. 3).
It also operates as a calculating means and displays the search results as an image on the CRT 36.

FIG. 2 shows an example of the display screen of the CRT 36 displayed in this manner, and the upper right corner of the frame corresponding to the parked vehicle is displayed in red.

Next, a preferred example of a search operation for a parked vehicle will be described with reference to FIG.

FIG. 3 (Δ) is a flowchart showing a preferred example of a search operation for a reserved vehicle. A vehicle corresponding to a reserved vehicle is searched for from among the vehicles stored as queue data in the queue storage device 34 in the following manner.

First, when a search operation is started, the arithmetic device 24 reads vehicle data stored as vehicle row data one by one from the row storage device 34.

Then, it is determined whether or not the vehicle is a specification vehicle, ie, a reserved vehicle, in which the parts stored as missing part numbers in the part number storage device 38 are to be assembled. If it is determined that the vehicle is on hold, the hold flag of the vehicle is turned on, and this hold flag is stored in the queue storage device 34.

Then, when such a reserved vehicle search operation is completed, a command to display the reserved vehicle is output next.

FIG. 3(B) shows a flowchart illustrating a preferred example of the reserved vehicle display operation. The vehicles are classified into reserved vehicles and non-reserved vehicles based on whether or not the is turned on.

Therefore, on CR-T'36, it falls under the category of a reserved vehicle.''
The top right corner of each frame is displayed in red, and the frame corresponding to a non-reserved vehicle is displayed normally.

In this way, in the apparatus of the embodiment, the storage position of the parked vehicle is simultaneously displayed on the CRT 36 together with the vehicle arrangement data.

Further, FIG. 3(C) shows an example of flowchart 1 showing the updating operation of the display screen of the CRT 36.

In the apparatus of the embodiment, storages 1 to 10. assembly line 16
Or, when a vehicle is brought in or taken out of the splash area 18, the arithmetic unit 24 calculates a new vehicle line-up, and the data in the line-up storage device 34 and the display screen of the CRT 36 are updated.

In this way, according to the apparatus of this embodiment, the operator can
Based on the display 36, it is possible to immediately know whether or not the next vehicle to be taken out from the storage 10 is a reserved vehicle.

Therefore, unlike conventional devices, there is no need for the worker or the parked vehicle to perform an extra operation of having the card reader 14 read the vehicle card, so that the vehicle is parked in the hold line 16 or the splash area 18. Vehicles can be stored quickly and easily.

In particular, according to this embodiment, it is possible to immediately know from the display on the CRT 36 whether the reservation line 16 is within the reserve line 16 or whether the reserve line 16 is full.
It becomes possible to immediately store the parked vehicle taken out from the vehicle into the ejecting area 18, and the work efficiency can be greatly improved compared to conventional devices.

In addition, in the device of this embodiment, when there is a report from the assembly line work site that the out-of-stock condition of a predetermined part has been resolved, the part number is sent to the part hole elimination data from the pending work setting device 32 in the control room 100. You can enter it as such.

As a result, the part number is cleared from the part number storage device 38, and the red display of the vehicle that uses the part disappears on the screen of the CRT 36, allowing the operator to know that the part shortage condition of the vehicle has been resolved. I can recognize it.

In particular, with the device of this embodiment, even when several types of parts are missing and only a specific part is removed, the CRT display screen shows that -16 parts are missing. Only the red display on the vehicle disappears. Therefore, even in a case where a parked vehicle and a vehicle whose parts shortage has been resolved coexist, the worker can accurately identify the two.

In addition, in the device of this embodiment, when the state of missing parts of vehicles stored in the assembly line 16 or the push-out area 18 is eliminated, and these vehicles are to be input to the assembly line, the In advance, the vehicle card of the vehicle is read by the card reader 14, and the parts instruction flyer is printed on the printer 1 for assembly.
~Let it out.

At this time, the calculation device 24 automatically detects the removal of a vehicle from the holding line 16 or the ejecting area 1B by taking in the information read by the card reading device 14, and calculates new vehicle row data. It is configured to update the data stored in the array storage device 34 and the display screen of the CRT 36.

In the above embodiment, the case where a vehicle is carried in and out as a workpiece into the storage 10 has been explained as an example, but the present invention is not limited to this, and can be applied to other types of workpieces. Needless to say.

Further, in the above embodiment, the case where a CRT 36 is used as a means for displaying pending work has been explained as an example, but the present invention is not limited to this, and it is also possible to appropriately adopt other display means as necessary. .

[Effects of the Invention] As explained above, according to the present invention, it is possible to accurately display the pending work stored in the storage, so that the work output from the storage via IWI can be divided into pending work and non-suspended work. It becomes possible to quickly sort the workpieces, store the pending workpieces in the holding area, and efficiently supply the non-holdable workpieces to the next process.
