A handling device (1) for tubular or elongate bowl-shaped workpieces such as pipette tips (4) or cups, said workpieces preferably being transported or being able to be transported on a workpiece carrier (T) during the production of said workpieces until packaging, the workpiece carrier (T) having receiving places (5) for the workpieces, which receiving places are arranged in a grid relative to each other, preferably with the stipulation that faulty workpieces located on the workpiece carrier (T) can be detected, and preferably with the stipulation that a removal station (25) is provided, by means of which the faulty workpieces can be removed from the receiving places (5) of a workpiece carrier (T), receiving places (5) thus being freed up, freed-up receiving places (5) of the workpiece carrier (T) being able to be loaded with faultless workpieces by means of the handling device, the handling device comprising a refill magazine (2), which has magazine places (3) arranged next to each other, each magazine place having a holding element (7) that can be moved up and down and that is used to secure and to receive and release a faultless workpiece, with the additional stipulation that each magazine place (3) comprises a guide tube (6), in which the up and down movement of the holding element (7) occurs, the holding element (7) being able to be moved, together with a secured workpiece, into the guide tube (6), and that an acceleration apparatus (V) is provided, by means of which the workpiece can be accelerated out of the guide tube (6) and can be moved to a receiving place (5) of the workpiece carrier (T).

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.

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.

A molding system for assembling a part by moving a workpiece gripped by a hand of a robot toward a mold of an injection molding machine, while rotating a molded article supported on the mold and the workpiece relative to each other, whereby the molded article and the workpiece are screw-engaged. The molding system includes a rotation detector for detecting a rotational amount between the molded article and the workpiece, an assembled state judging unit for judging if the assembled part is in a predetermined state, and a control unit for relatively rotating and displacing the molded article and the workpiece until the rotational amount exceeds a predetermined rotational amount and the assembled state becomes the predetermined state.

A method for injection molding comprises forming a set of first articles in a mold of an injection molding machine and forming a set of second articles in the mold of the injection molding machine. The method includes transferring the set of first articles from the mold to a first set of first receivers of a tooling plate, and then moving the first set of first receivers to align with the set of second articles. Thereafter the set of second articles is transferred from the mold toward the first set of first receivers and into assembled condition with the set of first articles held in the first set of first receivers.

A molding system capable of performing highly accurate work on a molded article with a molded article removal device. The molding system includes a molding machine, a molded article removal device capable of removing a master work installed in a mold of the molding machine, a measurement section configured to measure a position of the master work when the master work is removed by the molded article removal device, a displacement calculation section configured to calculate a difference between a reference position and a detected position of the master work measured by the measurement section as a displacement, and a correction section configured to, on the basis of the displacement calculated by the displacement calculation section, correct a work position for when the molded article removal device performs work on a molded article.

An injection molding machine includes a first mold section comprising mold cores for forming threaded articles, the first mold cores movable between a molding position for interacting with a second mold section in a mold area to form the threaded articles, and an auxiliary position outside the mold area, and a removal device for removing the threaded articles from the mold cores. The removal device includes a plurality of unscrewing chucks for engaging the threaded articles when the mold cores are in the auxiliary position. The chucks are supported by a carrier plate and each chuck is rotatable about a respective unscrewing axis. The removal device further includes an orbiting plate coupled to the unscrewing chucks by respective crank arms, the orbiting plate effecting synchronized rotation of the unscrewing chucks via the crank arms for unscrewing the threaded articles from the mold cores.

A method for cooling molded preforms includes transferring preforms of a first injection cycle from a mold to retained engagement on a take-out plate, the preforms having exterior surfaces and interior surfaces targeted for cooling. The preforms are released from cooling tubes of the take-out plate to retained engagement on cooling pins of a transfer shell spaced away from the mold. The transfer shell rotates and the preforms are released from the transfer shell to retained engagement in supplemental tubes of a supplemental cooling device. After a period of time the preforms are released from the supplemental cooling device and transferred back to retained engagement on the transfer shell. The transfer shell rotates to an unload position to eject the preforms from the transfer shell for evacuation from the machine.
