Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an improvement in a parts storage device that allows parts to be put in and taken out by oneself.

[Technical background of the invention]

In recent years, for example, production efficiency has improved on electronic device production lines by making various processes such as parts attachment and assembly self-help, but in order to cope with this, it is necessary to efficiently supply parts to the above production lines. It becomes.

Therefore, recently, a parts storage device has been developed that automatically takes in and out various types of parts used on a production line according to instructions from an operator. FIG. 4 shows an example of its configuration, which includes a parts storage section 1, lifters 2 and 3 for taking out and receiving parts to and from the parts storage section 1, and lifters 2 and 3 for taking out parts from the parts storage section by the delivery lifter 2. The conveyor 5 conveys the parts supplied to the station 4, and also conveys the parts supplied from the multiple stations 4 to the storage lifter 3. The parts storage section 1 has a multi-stage parts storage 1111 configured to move and circulate in the direction of the arrow in the figure by a chain mechanism or the like, and these parts storages 4111 store parts by type. A large number of component storage boxes 12 are stored. In addition, 13 is a rack for supporting each of the above-mentioned component storage shelves 11. On the other hand, each of the lifters 2 and 3 for exiting and entering the warehouse has a support column 21.3.
1 has a table 22.32 attached to it, and this table 22.32 moves up and down (in the direction of arrow B) with respect to the columns 21 and 31 by a lifting mechanism, and horizontally (in the direction of arrow C) by a rotation mechanism. It is designed to rotate. Thus, each of the lifters 2 and 3 takes in and out of the component storage box 12 from and into the component storage shelf 11 and transfers the component storage box 12 to and from the conveyor 5 by cooperating with the lifting/lowering and rotational movements of the table 22.32. Moreover, the conveyor 5 is a belt or the like that rotates a large number of rollers as conveyors arranged in the - row, and conveys the parts storage boxes 12 transferred from the unloading lifter 2 in the direction of the arrow in the figure. At the same time, the delivered or returned parts storage boxes 12 are conveyed to the warehousing lifter 3 by being manually pushed by an operator from each station 4. The transfer of the parts storage box 12 to each station 4 of the conveyor 5 or 5 is as follows:
This is done by a stopper (not shown) provided on the conveyor 5 so that it can move forward and backward.

On the other hand, FIG. 5 shows the configuration of the circuit portion of the above-mentioned component storage device. In the same figure, 61 is a central control circuit equipped with a processor as a main control section, and this central control circuit 61 is connected to a cyclic control circuit 63 via a bus control circuit 62.
, a lifter control circuit 64, a conveyor control circuit 65, and a station designation control circuit 66. The circulation control circuit 63 moves the component storage shelf 11 by a desired amount by driving the motor drive circuit 67 in accordance with a drive control signal from the central control circuit 61.

The lifter control circuit 64 receives the drive 1 from the central control circuit 61.
According to the 111E signal, drive signals are generated to drive the lifting and lowering mechanisms and rotating mechanisms of the lifters 2 and 3, respectively, and these drive signals are supplied to the lifting motor drive circuit 68 and the rotation motor drive circuit 69, respectively. The table 22,32 of each lifter 2,3 is controlled by the drive circuit 68,69.
to move up and down and rotate. The conveyor control circuit 65 drives the motor drive circuit 70 in accordance with the drive control signal from the central tIII11 circuit 61, thereby causing the conveyor 5 to transport the component storage box 12.

The station designation control circuit 66 drives the motor drive circuit 71 in accordance with the drive control signal from the central control circuit 61, thereby moving the stopper forward and backward to transfer the component storage box 12 from the conveyor 5 to the desired station 4. be.

Further, an operation section 73 and an output section 74 such as a printer are connected to the central control circuit 61, respectively.

The operation unit 73 is composed of, for example, a terminal device having a keyboard, and is used to input instructions for shipping and warehousing parts. At this time, the parts delivery instruction is given by inputting the name of the unit to be manufactured and the number l thereof. Output section 74
is for printing out a list of outgoing parts and incoming parts created by the central control circuit 61. It should be noted that a memory 75 is attached to the central control circuit 61, and this memory 75 stores the types and quantities of parts used for each unit.

Now, in the case of taking out parts in such a configuration, conventionally, for example, this is done as follows.

That is, the operator inputs the type and quantity of product units to be manufactured on the production line using the operation unit 73. Then, the central control circuit 61 first determines the type and quantity of parts to be used to manufacture the unit based on the input unit name according to the contents stored in the memory 75. Then, according to the result of this judgment, a drive control signal is output to the circulation system control circuit 63 and the lifter control circuit 64, respectively, to operate the parts storage shelf 11 and the lifter 2 for shipping, so that the judged parts are stored. The parts storage boxes 12 are selectively taken out and transferred to the conveyor 5. At this time, in parallel, the conveyor control circuit 65 drives the conveyor 5 to transport the parts storage box 12, and outputs a control signal to the station designation control circuit 66 to operate the stopper of the station 4 from which the delivery is desired. ,
This allows the parts storage box 12 to be moved to the desired station 4.
transfer to At the same time, the central control circuit 61
The previously determined parts names and quantities are printed out as a shipping list by the output unit 74 and notified to the operator. The operator takes out the specified quantity of parts specified in the delivery list from the parts storage box 12 and supplies them to the production line.

In this way, one shipment of parts is completed. In the same manner, the operator instructs the device to unload each unit using the operating section 73, thereby causing the device to unload the parts storage box used for manufacturing the unit, prints out the quantity of parts on the output section 74, and prints out the quantity of parts as required. The parts to be shipped are shipped unit by unit.

Therefore, the operator can issue the desired parts one by one by simply specifying the unit name.
As a result, the efficiency of shipping operations can be greatly improved and parts can be stably supplied.

It also has a great effect on labor saving.

[Problems with background technology]

However, in general, units often use common parts even if they are of different types. For this reason, if you only take out the warehouse in units as in the conventional device,
When it is necessary to unload parts from a large number of different units at one station, it is possible to unload parts for each type of unit and only one unit at a time. It took a lot of effort and time to finish shipping the products, and shipping efficiency was poor.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a parts storage device that can efficiently take out parts of a large variety of units in a short time even when parts are to be taken out of a warehouse, thereby improving delivery efficiency.

[Summary of the invention]

In order to achieve the above object, the present invention determines the type and quantity of parts used to manufacture each unit for each unit when unit names of multiple types of products are specified on the operation unit. The system drives and controls the parts storage shelves and the parts loading/unloading mechanism to deliver all the determined types of parts, and also calculates the total number of parts to be delivered for each type of parts and displays at least this total value. be.

[Embodiments of the invention]

FIG. 1 shows the main functions of a central control circuit of a parts storage device according to an embodiment of the present invention. In addition to the judgment means II, the system includes a part-specific delivery number calculation means 61a and a delivery list creation means 61b. The unit for calculating the number of outgoing parts by parts 61a sums up the quantities of used parts determined for each unit when multiple types of unit names are specified, and also calculates the number of used parts determined for each unit when multiple types of unit names are specified. In this case, the total quantity is calculated for each part. In addition, the shipping list creation means 6
1b is for making a table showing the total number of parts for each part calculated by the part-by-part number calculating means and the total number of parts obtained for each unit, and causing the output unit 74 to print out this table as a list for each part.

With such a configuration, for example, when the operation unit 73 specifies the names of units A, B, and C using codes, the central control unit 61 first identifies the types of parts used in each of the units A, B, and C. and quantity,
is determined based on the contents stored in the memory 75. Based on the result of this judgment, the parts storage box 11 and the delivery lifter 2 are each driven and controlled in order to take out all the parts used in each unit. Selective extraction and conveyor 5
The stoppers for specifying L15 and station 4 are respectively driven and controlled to unload each component storage box to a desired station. At the same time, the central control circuit 61 performs an output for each component based on the determination result of the type and quantity of the components.
[Calculate the total value of the quantities and print out the calculation result on the output unit 74.] For example, each unit A, 8.0
Figure 2(a) shows the types and quantities of parts used.

If the settings are as shown in (b) and (c), there will be a total of 4 parts a, 9 parts S, 2 parts C, etc.
..., calculate the total quantity of each part, and print out the results of these calculations.

On the other hand, if multiple types of unit names are specified as described above, and the quantity to be delivered for each unit is specified at the same time, when calculating the total quantity to be delivered for each part, first each unit A
, B, and C, and by summing the calculation results for each part, the total number of parts to be played is determined. For example, unit A is 10 sets, unit B is
If there is an instruction to ship 50 sets of unit C and 100 sets of unit C, for part a, unit A is 2 x 1
0-20 pieces, unit B is 1 x 50 x 50 pieces, unit C is 1 x 100 - 100 pieces, etc. The total number of parts to be delivered is calculated for each unit, and then the sum of these calculated values is 20 + 50 + 100. -170 pieces are calculated. Then, the total order quantity for each part calculated in this way is tabulated, for example, as shown in FIG. 3, and this is printed out on the output unit 74 as a delivery list. Incidentally, if the number of parts to be delivered is large and it cannot be delivered with just one parts storage box, a plurality of parts storage boxes containing the same parts are delivered.

Therefore, the operator can take out parts from each parts storage box delivered to the station while looking at this delivery list, and supply the parts to the production line or the like.

As described above, in this embodiment, when parts for multiple types of units are to be delivered at once, parts storage boxes for all parts used in each unit are delivered to the station, and each part is Since the total quantity of parts used in a unit is calculated and this total value is printed out, multiple types of unit parts can all be delivered in one delivery operation, thereby reducing delivery time. In addition, it is possible to reduce work effort and greatly improve delivery efficiency.

Note that the present invention is not limited to the above embodiments.

For example, a sticker coated with an adhesive on the back may be used as the recording paper used in the output section, and the printed out delivery list may be pasted as is on a tray of delivered parts and supplied to the production line. Furthermore, the mode of delivery may be selectable from among units, parts, and totals for each part. Furthermore, although a printer was used as a means for outputting the delivery list in the above embodiment, a display device such as a display may be used instead. Further, the circulation direction of the parts storage shelf may be only one direction, and the parts storage shelf may be one that reciprocates within a predetermined movement area, instead of one that circulates. In addition, the structure of the mechanical parts, the structure of the circuit parts, the form of the delivery list, the control procedure and contents of the central control circuit, etc. can be modified in various ways without departing from the gist of the present invention.

〔Effect of the invention〕

As described in detail above, according to the present invention, when the unit names of multiple types of products are instructed on the operation unit, the type and quantity of parts used for manufacturing each unit are determined for each unit, The parts storage shelf and the parts loading/unloading mechanism are driven and controlled to discharge all the determined types of parts, and the total quantity of the parts to be discharged is calculated for each type of parts and at least this total value is displayed. Accordingly, even when parts of a large number of different types of units are to be unloaded, they can be unloaded efficiently in a short time, thereby providing a parts storage device that can improve unloading efficiency.
