DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a work supply / discharge material apparatus and a work supply / discharge system which are responsible for inputting a work and discharging a processed work when a facility machine in a manufacturing industry is lined up. It is about the method.

[Prior art] FIGS. 8 (a), (b), 9 (a),
This will be described with reference to FIG.

 First, the operation of the workpiece supply and removal device will be briefly described.

In the present invention, the description will be made assuming that the maximum number of works entering the magazine is four. 8 (a) and 8 (b) are schematic cross-sectional views showing the configuration of a conventional workpiece supply / removal device.

In FIG. 8 (a), as for the material supply, a magazine (hereinafter, referred to as a full magazine) 80a containing the work 81 is placed on the upper stage, and when the automatic operation is started, one full magazine is added. Put on elevator 82a. The work contained in the magazine on the elevator 82a is sent out one by one to the main unit 88b according to a work request signal from the main unit 88b. Each time one sheet is fed out, the elevator 82a descends by one pitch.

When the work 81 in the magazine 80a becomes empty, FIG. 8 (b)
As shown in the figure, the magazine 80a is stocked in the lower row.

In FIG. 8 (a), when a magazine (hereinafter, referred to as an empty magazine) 80b containing no work in the lower stage is put on and the automatic operation is started, one empty magazine is lifted by the elevator 82b. Put on. When a work enters the magazine 80b on the elevator 82b from the main body device, when the work is detected by the work detection sensor 86, the elevator 82b is raised by one pitch.

When the work in the magazine 82b becomes full, the magazine 82b is stocked in the upper stage as shown in FIG. 8 (b).

FIG. 8 (a) shows a state in which a magazine is loaded on the elevator 82a of the material supply and one workpiece flows from the magazine 80a. On the material removal side, the work flowing from the material supply is stored in a single magazine 80b. In this example, the replenishment and removal materials each consist of a full magazine and an empty magazine.
It can be stocked individually. In addition, the transfer of the work between the supply and removal materials is of course the main unit 88b.
Via.

FIG. 8B shows a state in which the workpieces are successively taken out from FIG. 8A and stored, and the processing of the workpieces of the three magazines 80a is completed. As for the material, the work of the filled magazine has been discharged, and the empty magazine has been stocked in the lower stage. Work pieces are stored in empty magazines and are stocked in the upper row as full magazines.

FIG. 9A is a flowchart showing the operation of the material supply in FIGS. 8A and 8B. FIG. 9 (b)
8 (a) and 8 (b) are flowcharts showing the operation of material removal.

As can be seen from this example, in the conventional work supply / discharge material, only the work is discharged / stored, and the calculation / calculation of the number of works is performed.
The number of magazines has not been calculated. Therefore, if there are only three workpieces in the supply magazine, the magazine cannot be replaced unless the removal material has to be four, so the number of workpieces in the supply magazine is three or two. In the case of one sheet, the number of magazines supplied for supply and the number of magazines stored for removal do not match.

[Problems to be Solved by the Invention] With the configuration as shown in FIGS. 8 (a), (b), and FIGS. 9 (a), (b), the first three sheets / 2 2nd
If one piece of work per 3 pieces is included, the number of pieces removed is 1st piece 4 pieces / 2 pieces 3 pieces. Although the material is supplied in three magazines, the material is stored in two magazines when the material is removed.

In this case, for example, if the lots are different between magazines, the lots are mixed, and after the magazines are removed from the material removing device, it is necessary to manually sort the two magazines into three.

The present invention has been made in view of the above problems, and aims to eliminate this disadvantage, and to remove a workpiece in a magazine for material removal with the same number of workpieces in a supplied magazine. An object of the present invention is to provide a work supply / removal material device that can be stored.

[Means for Solving the Problems] A work supply / removal device of the present invention includes a work-in-magazine detection means for detecting the presence / absence of a work in a magazine supplied to a supply side; The supply work delivery number detection means for counting the delivery number, and the work counted by the supply work delivery number detection means in response to the detection of the completion of delivery of all the works in the magazine by the work presence detection means in the magazine. A work delivery number memory for storing the delivery number is provided.

Also, the work supply / discharge method of the present invention detects presence / absence of a work in a magazine supplied to a material supply side, counts the number of the workpieces sent out from the magazine, and detects presence / absence of a work in the magazine. The completion of sending out all the works in the magazine is detected, and the number of works sent out counted according to the detection is stored in a memory.

[Embodiment] Fig. 1 (c) shows an example of a configuration of a work supply / removal material device for realizing the present invention.

What has been added to the conventional configuration is the magazine detection sensor
15a, 15b, and 15c, and a work presence sensor 16 in a magazine. The operation and the operation method can be performed in the same manner as in the related art.

 The operation of the material supply will be described.

In the feeding, the number of magazines fed at once is counted (FIG. 2 (a)). Next, every time one work piece is sent out,
It is notified that one workpiece has been sent to the material removal (FIG. 2 (b)). Then, at the time when one magazine is finished, the material removal is notified that one magazine is finished (FIG. 2 (c)). Finally, when the magazines have been processed by the number of magazines supplied at one time, the material removal is notified that one lot has been completed (FIG. 2 (d)).

FIG. 3 (a) is a block diagram of the operation of material supply. Third
FIG. 1 (b) is a time chart 1 of a signal from supply to removal.
It is an example.

 Next, the operation of material removal will be described.

In the material removal, there are roughly two types of operations. The first method is to receive data from the supply and store it in memory. By sending signal from the material,
The number of fed sheets is counted (FIG. 4 (a)).
In response to a one-magazine end signal from the supply, the number of supply-per-magazine feeds is determined and stored in the memory. Then, the number of magazines that have been processed by the material supply is counted (FIG. 4B). The number of processed magazines in one lot of the supply material is determined based on the one lot end signal from the supply material and is stored in the memory (FIG. 4 (c)).

The second is to count the number of workpieces that have entered the material removal,
This is a method of replacing the magazine when the number of materials reaches the same.

By storing the work in the magazine, the number of removed materials is counted (FIG. 4 (d)). The number of supplied materials and the number of stored removed materials are compared, and if they match, the magazine is replaced (FIG. 4 (e)). Compared with the number of processed magazines in the supply, if they match, a sequence of one lot end is performed (FIG. 4 (f)).

FIG. 5 is an operation block diagram of the material removing apparatus according to the present invention.

When the above operation is performed, as shown in FIGS. 6 (a) to 6 (d), if four magazines are contained in the magazine on the material supply side, four magazines are stored on the material removal side. If the number is three, the number is three, and if the number is two, the number is two.

FIGS. 7A to 7D show the number of magazines for each lot. For example, if the supply is 3 magazines and 1 lot,
Material removal is also discharged as one lot of 3 magazines. 5A to 5D, the left side is the material supply side, and the right side is the material removal side. The magazine 10a moves from left to right.

Here, when the process is performed in one lot of three magazines on the material removing side, for example, when material is supplied in a configuration in which two magazines contain a work and one magazine does not contain a work, the material removal is performed. In the same way, one magazine can be removed without inserting a work. By doing so, the magazines flowing in the process can be easily flowed as one lot of three magazines at any time, and the management of the magazines becomes easy. In particular, when the work is heavy, it can be easily flowed in the same lot and in the same lot configuration in any process.

In addition, since the lot removing apparatus can recognize the lot configuration, it is possible to display the number of works entering each magazine and the total number of works in one lot at the end of one lot. If the number is transferred to the flow slip of the process, the entry of the flow slip becomes easy and accurate. When the number of works in each magazine and the total number of works in one lot are sent to the host computer, computer-managed processes can be realized.

Also, the signal format between the material supply and the material removal is arranged, and the signal is exchanged with the main unit. In other words, if a signal indicating that the number of workpieces was added or removed from the main unit from the main unit was added, the processing of the main unit failed, and if the operation of discarding the defect was performed, this operation was used to remove the defect. You can tell that the number has decreased. With this signal, the magazine can be automatically exchanged without any manual operation even if the removed material is defectively dropped.

This work can be added or removed anywhere in the material supply, material removal, or main unit, and any number can be attached.
This eliminates the need for a person to move the process unnecessarily to adjust the number of workpieces, and the process can be performed quickly.

[Effects of the Invention] The same number of magazines can be delivered from the magazine for supply to the magazine for removal.

Even if the magazine is not full of material from the material supply device, the material removal device will remove the same number of materials as the material supply device, so there is no need to manually replace the magazine because a person is attached to the material removal device. . The removing machine can be operated fully automatically, and a line of labor saving can be realized.

From the beginning of the process of feeding raw materials to the final process of completing a product, one lot can always flow with the same number of magazines. For this reason, the same number of magazines always flows in the factory according to the production quantity, so that it is possible to easily manage the number of magazines and the identification of the magazines which magazines are used.

For example, consider the exchange of magazines between step A and step B.

The work goes to the B step after the A step. The work completed from the material removing device in the step A is sent to the material supplying device in the next step B.

A charged magazine containing works flows from the material removal in the step A to the material supply in the step B. The empty magazine that has been supplied in the step B is returned to the material removal in the step A.

By repeating this process, there is a total of 9 magazines between the material removed in the process A and the material supplied in the process B, 3 + 3 = 6 magazines in the material removed in the process A, and 3 magazines in the material supplied in the process B. The work can flow from the upstream process to the downstream process without interruption.

Since the number of magazines in each lot is constant, the management of the number of lots is simplified. Since a fixed number of magazines can be handled for one lot, the number of lots flowing in the factory can be easily managed.
