  • Patent number: 11331712
    Abstract: A transfer mechanism includes a rail, first and second tables on the rail, first and second arms each having a base pivotably supported by the first and second tables, respectively, and first and second drive mechanisms that move the first and second tables along the rail, respectively. The first and second arms are pivotaly connected to each other at a position between a tip side and a base side. Tip side portions of the first and second arms than a connected portion of the first and second arms serve as fingers for holding a workpiece. The first and second drive mechanisms independently move the first and second tables, respectively. A relative movement of the first and second tables causes the first and second arms to operate a clamp/unclamp operation. A coordinated movement of the first and second tables causes the first and second arms to perform an advance/return operation.

    Abstract: An auxiliary device and a method for finishing and calibrating preforms that are removed from a multiple tool in an unstable shape, the calibration process being performed with compressed air immediately after removing and withdrawing the preforms from the multiple tool. Nipples that can be inserted into the preforms are provided with expandable press rings or sealing rings in order to seal the interior of the blow-molded part of the preforms. The compressed air is introduced via the nipples, the sealing process being performed by radially expanding the press rings or sealing rings in analogy to the closing process of thermoses, thus protecting the preforms from adverse forces. The sealing point can be randomly selected in the transition zone from the threaded part to the blow-molded part of the preforms. The interior of the blow-molded part is optimally sealed without affecting the form stability and dimensional stability of the preforms.

In accordance with an alternative embodiment of the invention a cam arrangement links the slide member and the mold base enabling a positive contact between the confronting surfaces when the slide member is arranged in the in-mold position, and providing a gap between the confronting surfaces during at least a portion of an interval when the slide member is moving.

  • Patent number: 7101506
    Abstract: Apparatus and method for transferring hollow blow molded articles from a vertically disposed wheel blow molding machine to a horizontally-disposed takeaway conveyor. Each mold on the wheel releases multiple blown articles at the six o'clock position on the wheel such that the articles fall freely from the wheel. An inclined end of a takeaway conveyor is located directly underneath the six o'clock position in order to receive the free falling blown articles and transport them to a horizontal transporting section of the takeaway conveyor. Flanges which extend upwardly from the conveying surface of the takeaway conveyor in combination with a powered endless positioning belt which extends a spaced distance along the inclined receiving end are utilized to confine the blown articles on the receiving end and uniformly position the blown articles on the takeaway conveyor.

  • Patent number: 6976836
    Abstract: In a biaxial stretch blow molding apparatus (10) for wide-mouthed containers, preforms (6) that are in an inverted state are conveyed on a single plane by preform carriers (40) that go around a carrier circuit (30) in the form of a loop, are heated via a heating station (60), and are then transferred via a transfer station (80) to stretch blow molding mold assemblies (72) that go around a circular looped path (71). The molded wide-mouthed containers (1) are taken out of the stretch blow molding mold assemblies (72) along a conveying path on a same plane and collected by a collection station (90). Wide-mouthed containers can be formed continuously and at high speed, which is less wasteful and more economical than the case where wide-mouthed containers that are formed from films.
