Japanese Patent No. 5016344

In the conventional molded product take-out machine, the operating status is often displayed on the display unit of the controller. However, it is often forgotten to look at the controller display on a regular basis. In addition, the lighting of the factory where the molded product take-out machine is installed is relatively dark, and when the molded product take-out machine is installed on the molding machine, it is difficult for the light to directly hit the inside of the mold, and the visibility is poor. This may be an obstacle when the operator visually recognizes the operation of the molded product take-out machine, or when the operating state is confirmed by a moving image or a still image captured by using an imaging device. Therefore, it may take time for the operator to know that the molded product take-out machine is not operating as set, and it may take time for the operator to know that a problem has occurred. is there.

An object of the present invention is to provide a molded product take-out machine provided with a light emitting unit that can be used for confirming the operation of the molded product take-out machine.

Another object of the present invention is to provide a molded product take-out machine capable of promptly notifying an operator of non-execution of a set operation operation or occurrence of a defect.

In the molded article take-out machine of the present invention in which the take-out head is provided at the tip of the approach frame via the attitude control device, one or more light emitting portions are attached to the attitude control device. According to the present invention, even when the lighting of the factory where the molded product take-out machine is installed is relatively dark, when the operator visually recognizes the operation of the molded product take-out machine, or a moving image or a still image captured by using an image pickup device. When checking the operating state, the light from one or more light emitting units can be used to check the operation of the molded product take-out machine.

Further, the molded product take-out machine of the present invention is provided with a take-out head at the tip of the entry frame via an attitude control device, and at least when the take-out head enters the mold of the injection molding machine in the attitude control device and the mold. One or more light emitting units that emit light in relation to the driving situation when exiting from the inside are visibly mounted from the outside of the attitude control device. If such a light emitting unit is provided in the attitude control device at the tip of the approach frame, the light emitting unit provided in the attitude control device can be used when the operator visually confirms the taking-out operation without looking at the display of the controller. Depending on the presence or absence of light emission, the operator can be made aware of the failure of the set operation operation or the occurrence of a problem. In addition, the lighting of the factory where the molded product take-out machine is installed is often dimmed from the viewpoint of energy saving. In such an environment, one or more light emitting units can also be used as local lighting.

When one or more light emitting parts are made to emit light when the set operation operation is normally performed, the light from the light emitting part of the attitude control device that moves near the mold is emitted to the inside of the mold or around the mold. It can be used as an illuminating light. As a result, the operator can check the situation inside the mold even in an environment where the interior lighting is dimmed. Needless to say, one or more light emitting units may emit light when the set operation operation is not normally performed. In this way, it is difficult to use the light emitting unit as lighting, but it is possible to notify the operator of the presence or absence of an abnormality.

The light emitting unit has a first light emitting surface in the opening / closing direction of the mold, and has a second light emitting surface adjacent to the first light emitting surface in the direction orthogonal to the opening / closing direction of the mold and the approach direction of the approach frame. It is preferable to have. In this way, the first light emitting surface serves as an illumination that illuminates the inside of the mold, and the second light emitting surface functions as an alarm for the operator to notice the non-execution of the set operation operation or the occurrence of a defect.

The light emitting unit is preferably configured to illuminate the first light emitting surface and the second light emitting surface with a common light source. By adopting such a configuration, the light emitting unit can be compactly configured.

The light emitting unit may have a light emitting surface in the opening / closing direction of the mold, and may be configured to illuminate the light emitting surface with a plurality of light sources. In this way, the light emitting portion can be used as much as possible as the illumination for illuminating the inside of the mold.

The light source can be composed of one or more light emitting diodes mounted on a circuit board. Since such a light source can emit light by using a circuit board of another circuit mounted in the attitude control device, the light emitting unit can be easily and inexpensively configured.

When the active control device that suppresses the vibration of the take-out head by applying the vibration of the opposite phase to the vibration of the take-out head from the electric actuator is further provided, the operation of the active control device sets the light emitting unit. It is preferably configured to cause the light source to emit light when it is done on the street. In this way, it is possible to make the operator aware of the non-execution of the set operation operation of the active control device by the light emission of the light emitting unit whether or not the active control device is operating as set. If the electric actuator is housed inside the attitude control device, active control can be efficiently executed by using a small electric actuator.

When at least one image pickup device is attached to the movable frame that moves during the extraction operation or the traveling body for moving the movable frame, the light emitting unit is a light emitting surface that illuminates the image pickup target of the image pickup device. It is preferable to have. When such a light emitting unit is provided, it is possible to improve the image quality of a still image or a moving image obtained from an imaging device.

That is, the operation of not only the molded product take-out machine 1 but also the injection molding machine 3 is adjusted so as to emit light when the operation is performed without delay according to the set procedure. In this way, as shown in FIG. 3, the light from the light emitting portion 37 of the reversing unit 33 that moves near the mold 35 of the injection molding machine 3 is used as illumination to illuminate the inside of the mold 35 and the periphery of the mold 35. can do. As a result, the operator can check the situation inside the mold 35 even in an environment where the interior lighting is dimmed.

On the contrary, in the other embodiment, the light emitting unit 37 does not emit light when the set operation operation is normally performed, and emits light only when an abnormality occurs. In still another embodiment, the light emitting operation of the light emitting unit 37 is switched between the normal time and the abnormal time. For example, the light emitting unit 37 repeatedly blinks, the blinking interval changes, and the color of the emitted light changes, so that the operator can visually recognize the abnormality.

Further, in another embodiment, the "operating condition" is not limited to the visible operation of the molded product ejecting machine 1, and the values of the voltage and air pressure supplied to the molded article ejecting machine 1 and the injection molding machine 3 are predetermined. This includes cases where the yield rate deteriorates in the subsequent inspection of molded products. The "operating status" is recognized by signals and data from various sensors and control devices input to a light emitting unit control device (not shown) that controls the operation of the light emitting unit 37, and is recognized according to preset determination criteria. , The light emitting operation of the light emitting unit 37 is determined.

The light emitting portion 37 of the present embodiment includes a cover 38 fitted to the window portion 46A, and the cover 38 has a first light emitting surface 39 in the opening / closing direction (Y-axis direction) of the mold 35, and the mold 35. A second light emitting surface 41 adjacent to the first light emitting surface 39 is provided in a direction (X-axis direction) orthogonal to the opening / closing direction and the approach direction (Z-axis direction) of the approach frame 31. In this way, as shown in FIG. 3, the first light emitting surface 39 becomes an illumination that illuminates the inside of the mold 35, and the second light emitting surface 41 makes the operator notice that the set operation operation is not performed or that a problem occurs.
