The sensing member 410 may be attached to the adsorption member 243 to detect in real time whether the injection-molded product 10 is properly adsorbed and positioned on the adsorption member 243 and transmit it to the controller 420 . For example, the sensing member 410 is composed of a sensor capable of detecting a transparent material such as the injection-molded product 10 and is connected to the controller 420 by wire or wireless, so that the injection-molded product 10 is transferred to the transfer module. It is possible to communicate with the controller 420 in real time by detecting whether the injection-molded product 10 is adsorbed on the adsorption member 243 while being transferred to the conveyor 300 by the 200 .

For example, the controller 420 calculates the time for the transfer module 200 to seat the injection-molded product 10 on the conveyor 300 in two rows and controls the movement of the conveyor 300 during the time. It is stopped, and when the time elapses, the conveyor 300 may be moved as much as the minimum length in the Y-axis direction of the injection-molded product 10 . For this reason, work efficiency can be increased by supplying the injection moldings to the operator in a form that maintains the same arrangement without a complicated configuration.

5 is a schematic perspective view for explaining a vision unit.

Referring to FIG. 5 , the injection molding apparatus 100 may further include a vision unit 430 .

The vision unit 430 may be disposed at a location where the external appearance of the injection-molded product 10 taken out from the injection module 20 can be inspected. For example, the vision unit 430 may be positioned in front of the transfer module 200 to capture the appearance of the injection-molded product 10 transferred by the transfer module 200 to perform an appearance inspection. Specifically, as shown in FIG. 2 , when the hinge 241 rotates forward before the Z-axis transport member 232 is lowered, the appearance of the injected product 10 is captured and based on the captured data, the It is possible to judge whether the injection product is good or defective.

The vision unit 430 may include a housing 431 , a heat dissipation fin 432 , a main board 433 , and a vision camera 434 .

The lower portion of the housing 431 may have an accommodating space provided therein, and a bottom surface and a portion of both side surfaces may have an open shape. The heat dissipation fin 432 is mounted on the open portion, and the heat dissipation fin 432 may provide an effect of dissipating heat generated from the main board 433 .

In addition, devices for operating the vision unit 430 including the main board 433 are built in the receiving space, and coupling means such as screws are inserted into the upper portion of the housing 431 inside each corner. A coupling portion to be formed may be combined with the components accommodated in the accommodation space.

The main board 433 stores and manages image data of the external state of the injection-molded product 10 received from the vision camera 434 disposed on the main board, and reads the image-capturing information to obtain a good quality product of the injection-molded product 10 . Alternatively, the transfer module 200 may be controlled by determining whether a defective product is present and transmitting a signal to the controller 420 . For example, when it is determined that the injection-molded product 10 is a defective product as a result of the external inspection of the injection-molded product 10 , the vision unit 430 transmits a signal to the controller 420 so that the transfer module 200 is currently By moving the injection-molded product 10 being adsorbed to a defective product tray (not shown), the operation efficiency can be greatly improved by filtering out the defective injection-molded product and providing only the good-quality injection-molded product to the conveyor 300 .

The vision camera 434 may be connected to the main board 433 through a wired/wireless communication network to enable mutual data communication. In the main board 433, reference image information for the injection-molded product, reading reference information, and a reading process are preset by the operator, and the reference image information for the injection-molded product and the vision camera 434 captured by the preset reading process are preset. By comparing the data, it is possible to determine whether the injection-molded product 10 is a good product or a defective product.

More specifically, the main board 433 may include a storage unit and an analysis unit.

The storage unit sets reference image information including information such as the contour shape, surface shape, dimension, color, etc. of the good-quality injection-molded product, and the reference image information determines the level of similarity with the appearance information of the injection-molded product captured by the vision camera 434 . can be used as a basis for

In addition, when setting the reading process, the level of similarity between the imaging information and the reference image information may be set as a criterion for judging whether the injection-molded product quality standard is met by the operator.

The analysis unit may determine whether the quality standard for the injection-molded object to be inspected is suitable by determining a similarity level between the reference image information and the imaging information according to a reading process stored in the storage unit.

The analysis unit may determine whether data on the injection-molded object to be inspected, ie, reference image information, reference information for reading, or whether a reading process is set for the injection-molded object to be inspected. When there is a preset detail of the data to be inspected, a similarity level between the imaging information acquired from the vision camera 434 and the reference image information may be determined, and the similarity level between the imaging information and the reference image information is the same If it exceeds the set similarity level, it may be determined as a good product, and if it is less than the similarity level, it may be determined as a defective product and transferred to the defective product tray (not shown).

6 is a flowchart for explaining the entire process of the injection-molded product take-out apparatus.

Referring to FIG. 6 , the sensing member 410 may include a distance sensing sensor (not shown) such as an ultrasonic sensor or an infrared sensor. Thus, the distance sensor (not shown) is installed in the suction member 243 to determine whether the injection-molded material is adsorbed by the suction means and transmits distance data from the injection-molded product to the controller, and The controller compares the distance data received from the sensing member 420 with a normal range when the injected product 10 and the suction member 244 are properly suctioned. When it is less than or exceeding the input normal range, it is determined that the ejected material is abnormally adsorbed to the adsorption means, the vacuum of the suction member is released to remove the ejected material, and the control returns to the initial stage of the injection material adsorption process. In addition, after the time measurement for moving the conveyor is reset at the same time as the vacuum is released, the time measurement can be restarted from when the adsorption member adsorbs the injection material again. When it repeatedly falls below or exceeds the normal range, the operation of the injection molding apparatus 100 may be stopped.

In addition, the sensing member 410 may further include a load cell (not shown). The load cell (not shown) is respectively disposed between the support plates 242 and the hinge 241 on the one side to provide weight information of the adsorbed injection product, that is, the pair of plates 242 and the adsorption member 243 . ), the adsorption means 244 , and weight data including the injection product may be transmitted to the controller 420 .

Based on the weight data received from the load cell (not shown), the controller 420 compares the weight information of the normally injected injection product written in the controller 420, When the area exceeds or falls short of the area, the injection-molded product 10 is determined to be defective, and the controller 420 may control the transfer module 200 to be transferred to a defective product tray (not shown). As such, the difference in weight between the weight of the injection-molded product 10 and the injection-molded product normally injected is due to the presence of a cavity inside or a defect in injection or flow of other resin moldings. If the standard weight deviation is preset and deviates from the normal range data, it may be determined as a defective product. The injection product deviating from the data within the normal range may be transferred to a defective product tray (not shown) disposed adjacent to the conveyor 300 .

In addition, the controller 420 may further include a fingerprint reader (not shown).

The fingerprint recognizer (not shown) may load the identification work speed data of the operator when the operator recognizes a fingerprint. The loaded working speed may be classified into three grades based on the average number of injection moldings that the operator moves per minute. For example, a case in which the average number of injection moldings moved per minute by the operator is 4 is classified into 2 grades, and if the average number of injection moldings moved per minute exceeds the 2 grades, it is classified into 1 grade, and if it is less than the 2 grades, it is classified into grade 3, By transmitting the work speed class data to the controller 420 , the controller can control the injection module 20 and the transfer module 200 . The controller 420 may control the speed of the injection module 20 and the transfer module 200 using the loaded speed class of the operator. For example, when the worker's work speed class is classified into 3 grades, the controller 420 sets the injection and feed rates of the injection module 20 and the transfer module 200 to the worker's work speed. By controlling the injection module and the transfer module, the average number of injections transferred per minute may be controlled to operate as three or two.

In addition, the controller 420 may control the speed of the injection module 20 and the transfer module 200 by grasping the operation speed of the operator in real time. For example, when the average number of injection moldings transferred per minute by the worker whose work speed class is classified as 2 is less than 4 over time, the controller 420 displays the changing work speed class in real time. The injection module 20 and the transfer module 200 may be controlled according to the sensed and changed work speed class.

In addition, the controller 420 may calculate the speed grade that the operator changes over time through the previously stored change data of the speed grade of the operator. For example, when the operator starts work, the speed class is classified into 2 grades, and as time goes by, the number of injections moved per minute decreases and the speed grade changes to 3 grades by storing data, may control the speed of the injection module 20 and the transfer module 200 by automatically calculating a change in the speed grade from the data during a later operation.

For example, when the diameter of the gear 629 on the driving member side is formed to be smaller than the diameter of the gear 627, the operator can rotate it with a small force. Accordingly, the gear 627 and the gear 629 on the driving member side may be appropriately formed to fit the situation.
