Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device and a setting processing method for a molding machine with a take-out machine, in which a take-out machine for taking out a molded product is attached to a main body of the molding machine.

[0002]

2. Description of the Related Art Conventionally, an injection molding machine (molding machine with a unloader) provided with a unloader (unloading robot) capable of automatically taking out a molded article is disclosed in, for example, Japanese Patent Laid-Open No. 11-584.

However, in the above-described conventional molding machine with a take-out machine, since the setting operation is performed individually by both the molding machine controller and the take-out machine controller, the molding conditions and the take-out conditions that are closely related to each other are set. It is not easy and quick to adjust and adjust the conditions, and mistakes are likely to occur. On the other hand, if all the setting functions are integrated in the molding machine controller side and all the setting work can be performed by the operating section of the molding machine body, such problems will be solved and the mounting machine controller will be simplified. Can contribute,
On the other hand, it is extremely inconvenient in the correction and change work in which fine adjustment is performed while confirming (observing) the operation of the unloader from the proper position and angle.

The present invention has solved the problems existing in such conventional techniques, and in addition to being able to facilitate and speed up the setting work for both molding conditions and take-out conditions that have a close relationship, In particular, it is an object of the present invention to provide a connecting device and a setting processing method for a molding machine with a unloader, which can make correction changes (fine adjustments) to the setting of unloading conditions (teaching contents) more easily and with high accuracy.

The relationship between the open / closed states is as shown in FIG.

Therefore, by using the unloader connecting device J as described above, it is possible to switch the power supply or the power supply release to the unloader R by the operation of the first switch portion 17, and in conjunction with this, the molding machine body Mo and Since the unloader R can be interlocked or released, unnecessary power consumption can be eliminated. Further, since the connector portion, the connection cable with the plug portion, the dummy plug, and the like are unnecessary, it is possible to eliminate the troublesome attachment / detachment work, and it is possible to reduce the cost by reducing the number of parts. Moreover, since the protrusion does not exist on the outer surface of the molding machine main body Mo, it is possible to contribute to improvement in appearance (commercial property).

Next, the configuration of the control device 1 according to this embodiment will be described with reference to FIG. The figure shows the control device 1
The block diagram of is shown.

In FIG. 1, 28 is a base 20 of the molding machine body Mo.
It is a molding machine controller unit provided inside. The molding machine controller unit 28 includes a molding machine controller main body 3a and a human machine interface (HMI).
5. A molding machine memory 3b is provided, which functions as a computer processing unit. The molding machine controller body 3
The molding machine controller 3 is composed of a and the molding machine memory 3b. Further, the operation section 2 attached to the front panel section 25f is connected to the HMI 5. In this case, the molding machine controller body 3a mainly functions as a programmable logic controller (PLC) that performs sequence control, and includes a CPU, a communication interface, a power supply unit 16, and the like.

On the other hand, the unloader controller unit 33 of the unloader R includes a unloader controller main body 4a and a unloader memory 4b, which function as a computer processing section. The unloader controller body 4a and the unloader memory 4b constitute the unloader controller 4. The pendant cable 34 of the operation pendant 6 described above is
It is connected to the unloader controller body 4a via the connector 47. The connection cable C led out of the unloader controller unit 33 is transferred to the molding machine controller unit 2 via the unloader connection device J provided in the molding machine body Mo.
Connect to 8. In this case, the connection cable C includes a main connection line Lm that connects the unloader controller body 4a and the molding machine controller body 3a, and an auxiliary line Ls that connects the connector 47 and the HMI 5.

Next, a setting processing method according to the present embodiment using such a control device 1 will be described with reference to the drawings and according to the flowchart shown in FIG.

First, the molding conditions of the molding machine main body Mo and the take-out conditions of the take-out machine R are set using the operation section 2 of the molding machine main body Mo (step S1). In this case, since the HMI 5 and the unloader controller body 4a are connected by the auxiliary line Ls, the HMI 5 is connected to the molding machine controller body 3a.
Not only can it be accessed, but also the unloader controller main body 4a can be accessed. Therefore, it is possible to set (change, add, delete) both the molding condition of the molding machine main body Mo and the take-out condition of the take-out machine R using the operation unit 2 of the molding machine main body Mo. Since the molding conditions of the molding machine main body Mo and the take-out conditions of the take-out machine R have a close relationship, the setting of both conditions by the operation unit 2 is realized, so that the matching adjustment of the molding conditions and the take-out conditions can be performed. Can be performed easily and quickly, and setting mistakes can be eliminated.

When the setting by the operation unit 2 is completed, the auxiliary setting for the unloader R is performed using the operation pendant 6 (steps S2, S3). In this case, the auxiliary setting is mainly a correction change (fine adjustment) of the teaching (teaching) content for the unloader R. As described above, since the setting process of both the molding condition and the take-out condition by the operation unit 2 is realized, the setting work can be facilitated and speeded up. On the other hand, however, the process related to the setting can be performed on the unloader R side ( Operation pendant 6)
If it cannot be done at all, it will be extremely inconvenient in the correction and change work for performing fine adjustment while confirming (observing) the operation of the unloader R from an appropriate position and angle. Therefore, the operation pendant 6 can be used to correct and change the teaching content shown in FIG. Thereby, the operator confirms the operation of the unloader R from an appropriate position and angle by holding the operation pendant 6 by hand after setting the molding condition and the unloading condition (teaching content) by the operation unit 2. However, it is possible to more easily and highly accurately make a correction change (fine adjustment) relating to the position, speed and timer shown in FIG.

When the modification / modification (auxiliary setting) process is completed, the extracted and modified extraction condition data is registered in the unloader memory 4b based on the original control of the unloader controller unit 33 (step S4). S
5). Thus, at the time of molding, the unloader R is drive-controlled based on the unloading condition data. Further, a data transfer command is output from the molding machine controller unit 28,
Based on this transfer command, the take-out condition data is transferred from the take-out machine R to the molding machine controller body 3a (step S6). As a result, in the molding machine controller main body 3a, the preset molding condition data and the corresponding take-out condition data are associated and registered in the molding machine memory 4b.
That is, the molding condition data and the take-out condition data are registered as a set. By the registration method as described above, a problem caused by registering the molding condition data in the molding machine memory 3b and the take-out condition data in the unloader memory 4b, for example, when the data is reused, the corresponding data is searched each time. Alternatively, the troublesomeness of separately performing the change processing and the like, and further, the reduction of the work efficiency and the processing error due to these are eliminated (step S7).

The embodiment has been described in detail above.
The present invention is not limited to such an embodiment,
The detailed configuration, shape, circuit configuration, exemplary items, quantity, method, etc. can be arbitrarily changed, added, or deleted without departing from the scope of the present invention. For example, the molding machine main body Mo and the take-out machine R are not limited to the examples, and can be applied to any type of molding machine main body and the take-out machine that can obtain the same effect.

[0028]
