Description

  The present invention relates to a molded product manufacturing system in cooperation with a molded product take-out machine and an injection molding machine that can automatically correct molding conditions necessary for molding a non-defective product.

  As molding conditions of the injection molding machine, control of the resin temperature, the resin filling pressure, and the mold temperature is important. Resin has different physical properties in the molten state depending on the type, but generally, if the temperature is too high, defects such as silver wire, foaming, and burning will occur, and if the temperature is too low, the viscosity will increase and fluidity will deteriorate. . Therefore, temperature control according to the physical properties of the resin is required. Usually, a temperature sensor is provided in the nozzle of the cylinder, and the resin temperature is directly measured to control the resin temperature.

  Also, if the filling pressure is too low, chipping occurs due to poor filling, and if the filling pressure is too high, there is a possibility that the dividing surface of the mold will open momentarily due to the pressure and burrs may occur around the molded product. is there. Usually, a pressure sensor is provided in the nozzle of the cylinder to measure the filling pressure of the resin to control the filling pressure.

Furthermore, the mold temperature is an important parameter that affects the shrinkage of the molded product and the transfer of the cavity surface to the molded product.
If the mold temperature is too low at the stage of resin injection into the cavity, the resin temperature will decrease and the viscosity of the molten resin will increase, resulting in flow marks, jetting, weld lines, and insufficient filling. If the temperature is too high, the temperature of the resin will be too high and burrs will occur or shrinkage will increase.

  Further, a heating / cooling passage through which steam or cooling water flows is formed in the mold, the mold is heated by the steam flowing through the heating / cooling passage, and the mold is cooled by the cooling water. In the cooling stage of the molded product, if the cooling time is shortened, the molding cycle is shortened, so that the mold temperature is increased as a whole. Further, if the cooling time is lengthened, the mold is cooled over a long time, so that the molding cycle is lengthened and the mold temperature is lowered overall.

  Therefore, if the cooling time is lengthened, the mold temperature is lowered, so that the temperature of the molten resin is lowered, the viscosity is increased, and it is difficult to fill the mold into the mold. As a result, the weight and dimensions of the molded product are reduced, which may cause sinks or deformation. On the other hand, if the cooling time is too short, the mold temperature increases, so that the shrinkage of the resin increases, and there is a risk of deformation.

  Therefore, conventionally, a quality determination of a resin molded product molded by an injection molding machine is performed, and molding conditions are reset based on the result of the quality determination. The pass / fail judgment is generally performed by visually observing the appearance of the molded product, and the operator resets the molding conditions of the injection molding machine from experience based on the result of the appearance observation.

  However, in the visual appearance inspection by visual inspection, it is not possible to determine whether or not a defect such as a “cavity (nest)” has occurred inside, and a defective product may still be generated.

  Therefore, the applicant conducts visual appearance inspection and measures the weight of the molded product when taking out the molded product with the suction head in the molded product take-out machine, and the range of the reference value in which the measured weight is recognized as a normal product. A system that re-sets the amount of resin to be filled so that the amount of resin falls within the allowable range of the reference value when the measured weight exceeds the allowable range of the reference value. Proposed (see Patent Document 1). According to this system, not only the appearance defect but also the quality of the molded product can be determined even if a defect occurs in the molded product, and the amount of resin can be adjusted.

Japanese Patent Laid-Open No. 2007-320070

  However, when determining the quality of a molded product by measuring the weight of the molded product, if the measured value exceeds the allowable range of the reference value, it is determined that a defect has occurred inside the molded product. However, it is not possible to automatically determine in which part of the molded product the defect has occurred, and for what reason the defect has occurred.

  In addition, in the case of a defect with a small weight loss such as generation of a flow mark, jetting, or a weld line, it may not be determined as defective only by the weight. In this case, the pass / fail judgment must rely on visual inspection. When the pass / fail judgment and the molding condition are reset by visual inspection, the pass / fail judgment varies, and the molding conditions are corrected. In some cases, reproducibility is poor because it depends on the skill level of the operator.

  The present invention has been made in view of the above circumstances, and provides a molded product manufacturing system capable of automatically setting molding conditions and improving quality without depending on the technical level of an operator. With the goal

The molded product manufacturing system according to the present invention is a molded product manufacturing system that manufactures a molded product in cooperation with an injection molding machine including a fixed mold and a movable mold and a molded product take-out machine that takes out the molded product from the injection molding machine. Because
The injection molding machine measures an injection unit for injecting molten resin into a cavity formed by a fixed mold and a movable mold, a first temperature sensor for measuring a resin temperature in the injection unit, and a mold temperature. A second temperature sensor, a pressure sensor for measuring the resin filling pressure, and a molding machine side controller for controlling the operation of mold opening or clamping of the movable mold and the operation of the injection unit,
The molding machine side control unit detects the temperature and mold clamping force of the mold, the temperature and pressure setting unit for setting the temperature and filling pressure of the molten resin in the injection unit, and the first temperature sensor, the second temperature sensor, and the pressure sensor. A temperature-pressure control unit that controls the mold temperature and clamping force, the temperature of the molten resin in the injection unit, and the filling pressure to be the set values set by the temperature-pressure setting unit based on the detection result ,
In the molded product manufacturing system provided with a molded product temperature sensor that is attached to a gripping part that grips the molded product and detects the temperature of the molded product immediately after being taken out from the injection molding machine ,
The part temperature sensor is configured to detect the temperature of the corresponding part near the gate of the injection molding machine in the part,
It has a molding condition correction unit for correcting various set values set by the temperature and pressure setting unit of the injection molding machine based on the molded product temperature detected by the molded product temperature sensor.

  By the way, when resin is injected into the cavity, if the resin temperature is low, the flow rate of the resin is slow, or the temperature of the mold is low, the fluidity is insufficient and the cavity is insufficiently filled. Marks and weld lines occur, and conversely, if the resin temperature is too high or the mold temperature is too high, sink marks will occur.

  Therefore, in order to accurately grasp the mold temperature and the resin temperature in the cavity, it is desirable to detect the cavity surface temperature, but it is difficult to detect the cavity surface temperature directly. The temperature near the internal cavity surface is measured. The cavity surface temperature is also affected by the temperature of the molten resin injected from the injection unit, so the temperature detected by the temperature sensor placed in the mold may not match the actual cavity surface temperature. .

  According to the molded product manufacturing system of the present invention, the temperature closest to the cavity surface temperature and the resin temperature are detected by detecting the surface temperature of the molded product immediately after molding, which is less affected by disturbance and is substantially the same as the cavity surface temperature. Therefore, it is possible to reliably grasp the molding state of the molded product.

  Then, in the molding condition correction unit, based on the surface temperature of the molded product detected when the molded product is taken out from the mold, various set values set by the temperature and pressure setting unit of the injection molding machine are set so as not to cause defective products. It can be corrected. As a result, the quality can be improved by automatically correcting the molding conditions without depending on the technical level of the operator.

In addition, the resin filled in the cavity changes its flow characteristics due to the structure of the runner and gate of the mold, and when the flow rate of the resin is high when passing through the gate, shearing force is generated in the resin and heat is generated. And thermal decomposition occurs in part and silver strips are generated.
Therefore, the molded article manufacturing system of the present invention, the molded article temperature sensor, which is configured to detect the temperature of a portion corresponding to near the gate of the injection molding machine according to the molded article tends gate near failure occurs By measuring the temperature of the molded product, it is possible to more effectively correct the molding conditions so as not to cause defects.

Further, the molded article temperature sensor is preferably configured to detect the temperature of the farthest portion from the gates in the molded article.
Since the viscosity of the part farthest from the gate in the molded product increases when the resin temperature is too low, the resin may not flow to the tip of the cavity. Therefore, by detecting the temperature of this portion, the molding state of the molded product can be grasped better.

Further, in the molded product manufacturing system of the present invention, the molded product take-out machine includes an appearance detection means for detecting the appearance of the molded product,
The molding condition correction unit corrects various setting values set by the temperature and pressure setting unit of the injection molding machine based on the molded product temperature detected by the molded product temperature sensor and the molded product appearance information detected by the appearance detection means. It is preferable to configure.
By adopting a configuration in which the molded product take-out machine is also provided with an appearance detection means, flow marks, weld lines, chips, and sink marks can be easily grasped based on the detected appearance information. Therefore, based on the detected temperature of the molded product. It becomes easy to determine the cause of the defect, and the molding conditions can be corrected more accurately.

Furthermore, in the molded product manufacturing system of the present invention, the molded product temperature sensor has a movable mold in a state where the fixed mold and the movable mold are opened and a gripping portion is disposed between the fixed mold and the movable mold. It is preferable to be configured to detect the surface temperature of the molded product immediately after molding disposed in the.

According to the molded product manufacturing system of the present invention, the temperature closest to the cavity surface temperature and the resin temperature are detected by detecting the surface temperature of the molded product immediately after molding, which is less affected by disturbance and is substantially the same as the cavity surface temperature. Therefore, it is possible to more reliably grasp the molding state of the molded product.
Based on the surface temperature of the molded product detected when the molded product is taken out from the mold, the quality is determined by setting the molding conditions so that defective products are not automatically generated regardless of the operator's technical level. Can be improved.

The mold temperature sensor 14 is provided near the cavity 34 and measures the temperature of the fixed mold 31 near the cavity 34.

  Further, the injection molding machine 1 includes a molding machine side control unit 5 that controls the operations of the mold unit 3 and the injection unit 4. The molding machine side control unit 5 includes a drive control unit 51 that controls the driving of each device of the mold unit 3 and the injection unit 4, and further, the temperature of the resin by the heater provided in the injection unit 4 that is a molding condition, screw The temperature and pressure setting unit 52 for setting the resin filling pressure by rotation of the rotation, the temperature of the fixed mold 31 and the movable mold 32 and the clamping force, and the temperature / pressure control unit 53 for controlling these temperatures and pressures. And a molding condition correction unit 54 that corrects the set value set by the temperature / pressure setting unit 52.

  The temperature / pressure control unit 53 is configured to set the resin temperature and the resin filling so that the temperature and pressure are set in the temperature / pressure setting unit 52 based on the detection results of the resin temperature sensor 12, the mold temperature sensor 14, and the pressure sensor 13.

  The molding condition correction unit 54 corrects the set value set by the temperature and pressure setting unit 52 based on the surface temperature of the molded product detected by the molded product temperature sensor 21 provided in the molded product take-out machine 2 described later.

  Further, the injection molding machine 1 transmits the operation data of the mold unit 3 controlled by the molding machine side control unit 5 and the molding conditions set by the temperature / pressure setting unit 52 to the molded product take-out machine 2, and the molded product. A transmission / reception unit 15 for receiving data from the unloader 2 is also provided.

  The molded product take-out machine 2 is a device that takes out a molded product from the movable mold 32 after the mold is opened to one side of the long side surface of the base portion 11. As shown in FIG. 1, the molded product take-out machine 2 sucks and holds the molded product molded by the injection molding machine 1 and a moving mechanism 6 including a so-called traverse type traverse arm 61, a pulling arm 62, and a lifting arm 63. And a plate-like suction head 7 serving as a gripping part.

  The transverse arm 61 extends in the width direction (arrow X direction) orthogonal to the axis of the injection molding machine 1, and one end thereof is fixed to a member that supports the fixed mold 31. One end portion of a drawing arm 62 extending in the axial direction (arrow Y direction) of the injection molding machine 1 is assembled to the traverse arm 61 so as to be movable back and forth in the arrow X direction. On the pull-out arm 62, an elevating arm 63 capable of elevating in the arrow Z direction is assembled so as to be movable back and forth in the arrow Y direction.

  The suction head 7 is attached to the lower end of the lifting arm 63, and the suction head 7 includes a plurality of suction members 71 whose contact surfaces with the molded product are circular. Each suction member 71 is evacuated by a vacuum generator (not shown) to be in a negative pressure state, and the molded product is sucked and held by the suction member 71 in this negative pressure state. .

  A molded product temperature sensor 21 for detecting the surface temperature of the molded product is attached to the suction head 7 at a position where there is no hindrance to the molded product suction. The molded product temperature sensor 21 detects the surface temperature of the molded product in a non-contact state with the molded product. As the molded product temperature sensor 21, a non-contact temperature sensor such as a radiation thermometer, a two-color thermometer, or a thermography is used.

  In the present embodiment, the molded product temperature sensor 21 detects the surface temperature of the portion corresponding to the gate of the fixed mold 31 in the molded product. When molten resin passes through a gate with a narrow passage area, defects are most likely to occur. When the flow rate of the resin is high, shearing force is generated in the resin, heat is generated, and thermal decomposition occurs in part, resulting in silver. Articles are generated. Therefore, by measuring the temperature of the molded product near the gate, it becomes easier to correct the molding conditions so that no defect occurs.

The unloader-side control unit 8 includes a drive control unit 81 that controls the driving of the arms 61, 62, and 63 of the moving mechanism 6 and the suction operation of the suction member 71, and further, the molding detected by the molded product temperature sensor 21. Based on the temperature of the product and the appearance image of the molded product imaged by the CCD camera 22, a pass / fail judgment unit 82 for judging pass / fail of the molded product is provided.

  When the quality determination unit 82 determines that the extracted molded product is a non-defective product, the drive control unit 81 is configured to move the molded product described later to the non-defective product collection unit from which the non-defective product is collected. When the drive is controlled and it is determined that the product is defective, the drive of the moving mechanism 6 is controlled so that the molded product is conveyed to a defective product collecting unit from which the defective product is collected.

  Furthermore, in the quality determination unit 82, the molding conditions set in advance by the temperature and pressure setting unit 52 of the injection molding machine 1 and the appearance image of the non-defective product are registered, and the quality determination unit 82 stores the molding conditions registered in advance. Then, the appearance image of the non-defective product is compared with the temperature detected by the molded product temperature sensor 21 and the appearance image captured by the CCD camera 22, and the quality of the extracted molded product is determined.

  Further, the molded product take-out machine 2 transmits the determination data determined by the pass / fail determination unit 82 including the temperature detected by the molded product temperature sensor 21 to the injection molding machine 1 and receives data from the injection molding machine 1. The transmitter / receiver 23 is also provided.

Next, the operation of the molded product manufacturing system according to this embodiment will be described.
First, resin pellets are charged into the hopper 41 in the injection unit 4 of the injection molding machine 1, and the movable mold 32 of the injection molding machine 1 is closed and clamped by the mold clamping device 33.

The resin melted by heating is injected and filled from the nozzle 43 of the injection unit 4. At this time, the filling pressure of the resin injected into the cavity 34 is obtained by the pressure sensor 13 provided in the nozzle 43 of the injection unit 4, the temperature of the molten resin is detected by the resin temperature sensor 12, and based on the detection result. Thus, the temperature and the filling pressure are controlled by the temperature pressure control unit 53. Based on the temperature detected by the mold temperature sensor 14, the fixed mold 31 and the movable mold 32 are controlled to be heated to the temperature set by the temperature / pressure setting unit 52 by the steam flowing through the heating / cooling passage.

  The molten resin injected and filled into the cavity 34 is solidified by cooling the fixed mold 31 and the movable mold 32. Also at this time, the fixed mold 31 and the movable mold 32 are controlled to be cooled to the temperature set by the temperature / pressure setting unit 52 by the cooling water flowing through the heating / cooling passage based on the temperature detected by the mold temperature sensor 14. When the molten resin is solidified, the movable mold 32 is opened by the mold clamping device 33, and the molded product can be taken out.

  When the movable mold 32 of the injection molding machine 1 is opened, a molded product take-out operation is executed in the molded product take-out machine 2.

When attracted and held and released from the movable mold 32, the appearance of the molded product is imaged by the CCD camera 22. The detected temperature and appearance image of the molded product are sent to the quality determination unit 82 of the unloader side control unit 8.

  After the quality determination of the molded product is performed, the quality determination unit 82 transmits the quality determination information including the surface temperature of the molded product from the transmission / reception unit 23 to the injection molding machine 1 and also extracts the quality determination information from the machine-side control unit. 8 is also sent to the drive control unit 81.

  The quality determination information including the surface temperature of the molded product transmitted from the molded product take-out machine 2 to the injection molding machine 1 is input to the molding condition correction unit 54 of the molding machine side control unit 5. The molding condition correction unit 54, based on the temperature detected by the molded product temperature sensor 21 and the appearance image captured by the CCD camera 22, when the quality determination information is information determined as a defective product by the quality determination unit 82. Then, the set value (molding condition) of the temperature / pressure setting unit 52 is corrected to a set value at which no defective product is generated.

  Next, the suction head 7 that has sucked the molded product is moved from the take-out position (B) to a predetermined molded product collection position (C) outside the injection molding machine 1 by operating the moving mechanism 6. When the molded product recovery position (C) is reached, the suction state by the suction member 71 is released and the molded product is released from the suction head 7. When the molded product is released from the suction head 7, the suction head 7 is returned to the predetermined standby position (A) again, and the molded product is sucked to the suction head 7 at the molded product take-out position (B) described above, The operation of transporting to the molded product collection position (C) is repeated.

  When the quality determination unit 82 determines that the extracted molded product is a non-defective product, as described above, the suction head 7 is moved to the molded product collection position (C), and the molded product is moved to this position. To release.

  On the other hand, when the pass / fail determination unit 82 determines that the extracted molded product is defective, the suction head 7 is moved to the defective product collection position (D) shown in FIG. In (D), the molded product is released.

  As described above, according to the molded product take-out machine 2 of the present embodiment, it is not necessary for the operator to bother to observe the state of the molded product and determine a defective product. Based on the detected surface temperature of the molded product and the appearance image captured by the CCD camera 22, the quality of the molded product is automatically judged. If a defective product is generated, the detected surface temperature of the molded product and The molding conditions in the injection molding machine 1 can be automatically reset based on the appearance image. As a result, the burden on the operator can be reduced.
