FIG. 9 is a flowchart showing the flow of part master registration that is first set to start using the parts collection work support system shown in FIG.

In the component collection work support system of this embodiment, the component master registration is performed by operating the component collection management device PC 100 and the display device 60 . First, the parts master editing screen shown in FIG. 6 is called up on the parts collection and management device PC 100, and the part name, model, manufacturer name, code, frontage number, etc. are entered on the parts collection and management device PC 100 (step SYS001).

Next, the operator operates the display device 60 at the frontage where the part is stored. First, the selection switch 63 is pressed to switch the mode, and the selection switch 63 and decision switch 64 are pressed to register the frontage number in the storage unit of the display device 60 (step SYS002). Next, register the part mass. By pressing the selection switch 63, the mode is switched to shift to the part registration (quantity calibration) mode (step SYS003).

With the storage container 202 in the state where no component is stored is placed on the mass detection device 50 at the frontage for storing the component, the decision switch 64 is pressed to register the zero point in the storage unit of the display device 60. (Step SYS004).

The parts to be stored in the storage container 202 are put in, the number of parts put in is registered in the storage unit of the display device 60 by pressing the selection switch 63 and the decision switch 64, and when the decision switch 64 is pressed, the mass of the parts put in is calculated. It is automatically measured and registered in the storage section of the display device 60 (step SYS005).

Further, when registering the tare mass, the storage container 202 is once returned to an empty state, the process returns to step SYS004, and the selection switch 63 is pressed to switch to the tare weight registration mode (step SYS004). Next, the tare parts are put in, the tare amount is registered in the storage unit of the display device 60 by pressing the selection switch 63 and the decision switch 64, and when the decision switch 64 is pressed, the mass of the parts put in is automatically measured. and registered in the storage unit of the display device 60 (step SYS005).

Finally, by pressing the determination switch 64, communication is started with the parts collection management device PC 100 to share the parts master data registered in the storage unit of the display device 60 (step SYS006).

In this embodiment, since the mass detection device 50 is installed at each frontage, registration is performed according to the procedure described above. It is also possible to use the mass detection device 50 and the display device 60 to perform the above-described component master registration work. In addition, when the parts mass, tare mass, parts inventory number, etc. of the parts to be stored are known in advance, they can be directly input to the parts master editing screen (FIG. 6) of the parts collection management device PC100.

Next, the flow of the component collection work performed by the component collection worker shown in FIG. 10 will be described with reference to the flowchart.

In the parts collection work support system of this embodiment, the parts collection work is performed by operating the parts collection management device PC 100, the mobile information terminal 80, the display device 60, and the like.
First, the parts collection management device PC 100 calls up the collection list screen of parts to be collected shown in FIG. 7 (step DSC001). At this time, if the parts collection truck 300 is to be used for the parts collection work, the truck number is entered.

Next, a component item to be collected is selected from the collection list displayed on the screen of the component collection management device PC 100 or the portable information terminal 80 (step DSC002). At this time, if the parts collecting operator does not select the parts items to be collected on the screen, the parts items to be collected are automatically specified.

From the parts collection management PC 100 or the portable information terminal 80, data such as the number of parts to be collected and the truck number is transmitted to the display device 60 at the frontage where the selected parts are stored, and the display device 60 lights up (step DSC003). ), and displays the number of collected items and the truck number (step DSC004).

At this time, data such as the part numbers of the parts to be collected, the number of parts to be collected, and the weight of the parts are also transmitted to the display device 60 loaded on the parts collection truck 300, and the display device 60 displays the number of parts to be collected, the part numbers, and the like. is displayed.

When the frontage display device 60 lights up, the parts collection worker confirms the parts or the trolley number on the frontage display device 60, then pulls out the drawer 201 and takes out the parts from the storage container 202 (step DSC005). ). Here, by displaying the truck number on the display device 60, it is possible to use a plurality of parts collection trucks 300 and simultaneously proceed with a plurality of parts collection operations.

At this time, the parts collector does not need to count the number of parts to be collected each time, and can collect the parts roughly. Specifically, for example, when the collection number displayed in the collection list is 100, the parts collector takes out the parts from the storage container 202 as a rough guideline. During the collection work, the mass detector 50 installed at the frontage detects changes in mass. The mass change data detected by the mass detection device 50 is sent to the display device 60, and the display device 60 converts the mass data into the number using the registered master data of the part. When the collected number at this time is 95, the display is updated to 5 obtained by subtracting 95 from 100 and displayed on the display device 60 . In the second collection operation, the parts collector picks up an approximate number of parts again, and repeats until the number display on the display device 60 becomes zero. By the way, when the parts collection worker takes out more parts than the collection number displayed in the collection list, the display of the display device 60 becomes a minus display, and the parts collection worker returns the excess number to the storage container 202. is displayed as 0 (step DSC006).

The operator confirms that 0 is displayed on the display device 60, recognizes the completion of collection of the part, and presses the decision switch 64 (step DSC007). The display device 60 transmits the number of parts to be collected to the parts collection management apparatus PC100, and the parts collection management apparatus PC100 corrects and updates the stock number of the parts (step DSC008).

The parts collection management device PC100 checks whether there is an uncollected part item in the collection list, and if there is an uncollected part item, automatically designates the part item. If there are multiple uncollected parts items, the parts collection worker can select an arbitrary parts item from the collection list displayed on the screen of the parts collection management device PC 100 or the mobile information terminal 80 ( Step DSC009). If there are any uncollected parts items, the process returns to step DSC002 to continue the parts collection work.

In this embodiment, since the mass detection device 50 is installed at each frontage, the parts were collected according to the procedure described above. Even in an embodiment in which the mass detection device 50 is installed and the mass detection device 50 is not loaded on the parts collection truck 300, the parts collection work can be performed in the same procedure. On the other hand, in the embodiment where only the display device 60 is installed at each frontage and the mass detection device 50 is not installed, the mass detection device 50 loaded on the parts collection trolley 300 and the display device 60 are used to perform the parts collection work described above. can do

Specifically, the steps up to step DSC004 are the same as those described above, and the parts collector takes out the parts from the storage container 202 and puts them into the collection tray 302 loaded on the mass detector 50 of the parts collection truck 300. (Step DSC005).

A mass detector 50 loaded on the parts collection truck 300 detects the change in mass. Mass change data detected by the mass detection device 50 is sent to the display device 60 mounted on the parts collection truck 300, and the display device 60 displays the mass of the part based on the part master data sent from the parts collection management device PC100. is converted into the number of parts, and the collected number displayed on the display device 60 loaded on the parts collection truck 300 is updated and displayed. At the same time, the data update information of the collected number is transmitted to the display device 60 installed at each frontage via the portable information terminal 80, and the display is updated (step DSC006). Depressing of decision switch 64 in step DSC007 can be performed by either an object installed at each frontage or an object loaded on parts collection cart 300, and step DSC008 follows the same flow as in the above-described embodiment.

Next, when there is an uncollected parts item, the process returns to step DSC002, the parts collection worker selects the parts item with the portable information terminal 80, and uses the mass detector 50 loaded on the parts collection cart 300. make a choice. At that time, the previously collected parts are placed in the collection tray 302, and the mass in that state is regarded as 0, and the mass detection device 50 detects the change data of the mass and converts the number. The subsequent steps follow the same flow as in the above-described embodiment.

Furthermore, the parts collection cart 300 is loaded with a mass detector 50 and a very small mass detector 70 that is used when detecting a particularly small mass, for example, a mass of 2 g or less. At the terminal 80, the mass detector 50 or the mass detector for very small masses 70 can be designated and used selectively.

Since the parts collection work support system of the present invention registers and manages the number of parts in stock, it holds the management data of the number of parts in stock. Furthermore, the mass data of the mass detection device 50 and the parts collection management device PC 100 installed at each frontage are compared, and if there is a discrepancy, a warning is given, and the result is displayed in the inventory list shown in FIG. By doing so, there is an effect that it can be used for more accurate inventory management.

As described above, the best configuration, method, etc. for carrying out the present invention are disclosed in the above description, but the present invention is not limited to this, and other embodiments, additions, modifications, etc. , deletion, etc., can be changed within the range that a person skilled in the art can conceive, and as long as the action and effect of the present invention are exhibited in any aspect, it is included in the scope of the present invention.
Therefore, the present invention can provide not only the execution method of the parts collection support system, but also a computer-readable program for executing the method and a recording medium on which the program is recorded.

Also, in the above embodiment, there are cases where the numbers of storage racks and parts collection trucks are not specifically described, but it is of course possible to use a plurality of storage racks and parts collection trucks.
