Description

  The present invention relates to a control device for an injection molding machine having a human machine interface configured to include a display and a touch panel.

Conventionally, this type of control device has been fixed and installed on the operation side or the non-operation side of the injection molding machine. Therefore, depending on the installation environment of the injection molding machine, the injection molding machine could not be installed to operate efficiently. In particular, when a plurality of injection molding machines were installed side by side, the effect was great. In addition, as seen in Japanese Patent Application Laid-Open No. 2001-088190, there is an example in which a control device is fixed and installed on the rear side of the molding machine, and a remote controller is detachably attached to the control device.
JP 2001-088190 A

  However, in the case where a plurality of injection molding machines are installed side by side as in the former, as shown in FIG. 4 (a), the control devices 1 to 4 are placed on the respective operation sides in a place A surrounded by a chain line. The injection molding machine 5 or the injection molding machine 8 is installed. In addition, when taking out a product from the injection molding machine 5 or the injection molding machine 8 installed on both sides from the product discharge space 9, the operation side of the molding machine must be in order to check the molding conditions while the molding machine is in operation. I had to stand up. In order to compensate for this drawback, the injection molding machines 7 and 8 are installed on the opposite side across the work space 10 in order to facilitate the operation of the injection molding machine 5 through the injection molding machine 8 as shown in FIG. The method was adopted. However, this method is also performed on the non-operation side of the injection molding machine so as not to disturb the operation of the product, and it is necessary to provide a product discharge space 12, which is large and inefficient. In addition, such an arrangement has the disadvantage that it is expensive and inconvenient in the product price of the injection molding machine.

  In addition, when the flourishing device is fixed / installed on the rear side of the injection molding machine as in the latter case, the control device itself is fixed / installed on the rear side of the injection molding machine. However, the cable connecting the control device and the operating device moves around the operating device wherever it moves. Therefore, not only the work is disturbed, but there is also an unfavorable situation such as deterioration of the tail pater scaffold.

  Furthermore, when a rationalization device such as a molding machine monitoring device, measuring device, or product removal robot is located near the periphery of the molding machine, the control device is the molding machine regardless of whether the control device is on the operation side or the non-operation side. Since it is fixed and installed in the machine, it is difficult to check the molding conditions during operation because the rationalization equipment obstructs the work, and the initial drawbacks are inevitable. This is because the control device is fixed and installed in the injection molding machine.

  An object of the present invention is to provide a molding machine control device that eliminates the disadvantage that the conventional molding machine control device is fixed and installed in the molding machine as described above, and efficient work and production cannot be performed. It is in.

  For this purpose, the control device may be a control device that can be moved freely so that efficient production and operation work can be performed without being fixed / installed on the injection molding machine. The conclusion was reached that the human machine interface only needs to be movable from the control unit and that the cable between the control unit and the human machine interface need only be disconnected.

  In order to achieve the above-mentioned object, the present invention provides a control device for an injection molding machine having a human machine interface configured to display and monitor the molding conditions of the injection molding machine and to have a display and a touch panel. The control device of the injection molding machine is characterized in that the control device is detachably attached to the injection molding machine.

  Further, when a plurality of injection molding machines are installed side by side, it becomes a control device for an injection molding machine capable of more efficient control.

  Further, it is more preferable that the human machine interface is detachably attached to the control device, and at least the human machine interface is movable.

  In addition, it is more preferable to perform setting / instruction of molding conditions, monitoring of operating conditions, etc. by wired communication or wireless communication using electromagnetic waves including infrared rays from a human machine interface moved to an arbitrary position around the injection molding machine.

  Furthermore, in wireless communication using electromagnetic waves such as wired or infrared rays, the control device of the injection molding machine is characterized in that the communication method used by the operator can be switched by a switch provided in the human machine interface. Is preferable.

  According to the present invention, since the control device, at least the human machine interface, can be moved and installed anywhere depending on the installation environment of the injection molding machine, the operation and various operations of the injection molding machine can be performed efficiently. We were able to overcome the problem of operability.

Next, an embodiment of the present invention will be described with reference to FIG. 1, taking as an example the case where four injection molding machines are installed side by side.
Injection molding machines 21 to 24 are installed at an installation place 20 surrounded by a chain line. These injection molding machines 21 to 24 are detachably mounted with control devices 25 to 28 having human machine interfaces 25a to 28a each composed of a display and a touch panel. A product discharge space 29 is provided between the injection molding machines 21 and 22 and the injection molding machines 23 and 24, and a work space 30 is provided in front of the injection molding machines 21 to 24 (lower side in the figure).

  If it is in such an installation state and the control devices 25 and 26 of the injection molding machines 21 and 22 are on the back side when viewed from the work space 30, the conventional control device is fixed and installed, molding conditions and the like However, in the present invention, the control devices 25 and 26, at least the human machine interfaces 25a and 26a, for example, as indicated by chain lines 25b and 26b, are required for the operator. It is possible to confirm the molding conditions from a remote location, and not only to confirm the molding conditions, but also to set / instruct the molding conditions and monitor the operating conditions by wire or wireless.

  Then, a control device for performing setting / instruction of molding conditions and monitoring of operating conditions by wire using the above-described cable or wirelessly such as infrared rays or radio waves, taking the control device 25 and the human machine interface 25b as an example, Referring to the block diagram of FIG. 2, the control device 25 has a CPU 11 for operation control of the injection molding machine 21, and includes a control program ROM 12 and a temporary storage RAM 13. Further, a sequencer 16 having a sequence control program for controlling the machine periphery of the injection molding machine, an input means 14 for receiving an input signal from the injection molding machine, and an output means 15 for outputting an output signal to the equipment of the injection molding machine.
