Apparatus for taking out molded product, method of estimating mass of taking portion of the apparatus, and method of taking out molded product
There are provided an apparatus for taking out a molded product that allows a physical amount such as the mass of the taking portion to be easily acquired with a relatively simple configuration. A posture reversing mechanism is provided between the elevating arm and the taking portion to change the direction of the taking portion between an unreversed state in which the taking portion is directed to be able to take hold of the molded product molded in the die, and a reversed state in which the length of the taking portion in the vertical direction is shorter than that in the unreversed state. A sensor detects vibration of the elevating arm. A mass estimating section estimates the mass of the taking portion on the basis of vibration of the elevating arm detected by the sensor when the taking portion is in the reversed state.
INJECTION MOLDING MACHINE FOR MOLDING PREFORMS
An injection molding machine includes a machine base extending along a horizontal machine axis; a stationary platen fixed to the base; a moving platen supported by the base; a center section supported by the base axially intermediate the stationary and moving platens; at least one mold stroke actuator for translating the moving platen and the center section along the machine axis between a mold-open position and a mold-closed position; a two-stage first injection unit supported by the base behind the stationary platen for injecting a first resin through the stationary platen; and a two-stage second injection unit supported by the base behind the moving platen for injecting a second resin through the moving platen. The second injection unit is translatable along the machine axis to accommodate translation of the moving platen during movement between the mold-open and mold-closed positions.
Injection molding system
In an injection molding system, a holding force changing means reduces a holding force to a predetermined level or less if a predetermined or higher load is detected by an external load detection means after a molded article is transported to a work area of an operator by a molded article transport device. Thus, the operator can easily take out and inspect the molded article.
Apparatus for taking out molded product and method of monitoring operations thereof
A cycle time administration section 3 of an apparatus for taking out a molded product of the present invention includes: a measurement section 5 for measuring a cycle time for every one cycle of taking out a molded product; a setting and storing section 7 for setting and storing a target cycle time; a comparison section 9 for comparing the measured cycle time and the target cycle time for every one cycle; a counting section 11 for counting the number of times that the measured cycle times consecutively exceed target time, following the measured cycle time that has first exceeded the target cycle time, if it is determined that the measured cycle time has exceeded the target cycle time as a result of the comparing; and an outputting section 13 for outputting a detection signal if the counted number of times is more than n times.
Apparatus for taking out molded product
An apparatus for taking out a molded product that is capable of suppressing displacement vibration of an attachment in a shorter time than ever without using a large-scaled electric actuator. An active controller performs active control in conjunction with the positioning, control by the servomotor. At the beginning of the active control, the positioning control is primarily performed by the servomotor, and then the active control is positively performed by the active controller using an electric actuator. Compared with when only the active control is performed for vibration suppression, a lighter and smaller electric actuator can be employed.
Apparatus for taking out molded product
An apparatus for taking out a molded product that is capable of suppressing displacement vibration of an attachment in a shorter time than ever without using a large-scaled electric actuator. An active controller starts active control after the amplitude of displacement vibration of the take-out head as an attachment has been attenuated to a predetermined setting by means of positioning control by a servomotor or when the amplitude can be considered as having been attenuated to the predetermined setting. The positioning control is first performed by the servomotor, and then the active control is performed by the active controller using an electric actuator which is light in weight and small in size.
REMOTE CONTROL SYSTEM FOR INJECTION MOLDING MACHINE
A remote control system to remotely control a take-out robot of an injection molding machine on a production site through network includes an injection molding machine to produce and convey injection molded products through the take-out robot. A remote controller transmits and receives the operation data of the take-out robot and the information data on the injection molding to and from the injection molding machine through the wireless internet. The remote controller remotely controls the injection molding machine based on the utilized operation data and information data. A control pendent connected to the injection molding machine remotely controls the take-out robot, performs three-dimensional graphic simulation for the previous operations before operating the take-out robot and for loading motions of the injection molded products, and stores and outputs the three-dimensional graphic images of the injection molded products, based on a previously stored remote control access program.
DEVICE FOR TRANSFER AND/OR HANDLING AND TRANSPORT OF WORKPIECES
The invention relates to a device for handling and/or transporting workpieces (5), in particular for removal of injection-molded items from an injection-molding machine, wherein a handling robot (4) having a programmable control and regulating unit (10) is provided that comprises a gripper (6) having at least one suction nozzle (7) for grasping of the workpiece (5) or fixating it by suction. In the gripper (6) of the handling robot (4) a distance-measuring device (8) for detection of the distance (a.sub.1+a.sub.2) from the gripper (6) to a reference point or a reference surface (9), for example to the mold tool half (2), which is preferably movable, with the workpiece (5), is provided. The measured value of the distance-measuring device (8) is fed into the control and regulation unit (10). The distance-measuring device (8) can be a light-transit time measuring device, in particular a time-of-flight (TOF) sensor.
INJECTION MOLDING SYSTEM AND INJECTION MOLDING METHOD
A numerical controller instructs a robot or an automated machine (external device), in relation to a main task for which a retrying operation thereof has occurred, to execute, instead of or in addition to the main task, a sorting task to distinguish an exception molded product, which was produced from a time when a determination result became successful, and until a physical quantity to be measured lies within a management range, or until a stand-by time elapses, from a normal molded product produced before the occurrence of the retrying operation.
Injection molding machine management system
There is provided an injection molding machine management system including an injection molding machine configured to mold a molded article with injection molding, a peripheral device configured to perform a post-process of the injection molding, and a control device communicably coupled to the injection molding machine and the peripheral device. The injection molding machine management system includes a generating section configured to generate a common identifier for each of predetermined production units and transmit the common identifier to the peripheral device. Molding data concerning the injection molding and post-process data concerning the post-process are correlated with the common identifier.
