Device and method for the production of two-dimensionally arched structural components from a fiber composite
A device and to a method for the production of essentially two-dimensionally arched large-area structural components from a fiber composite material, including a jig having a convex mounting surface which has longitudinally extending receiving channels for the insertion of construction components and which can be loaded with auxiliary materials, wherein the loaded jig interacts with a laminating bonding device having a corresponding shape for forming the structural component under pressure, wherein the jig includes a mounting shell that at the edge can be elastically deformed inwards, which mounting shell, by way of a plurality of actuators that are articulated to the inside, can be moved between an extended position (A) and at least one retracted position (B) in which the jig can be moved relative to the longitudinally extending receiving channels from the laminating bonding device without undercuts.
MANUFACTURING SYSTEM IN WHICH WORKPIECE IS TRANSFERRED
A manufacturing system includes a plurality of manufacturing process stations for processing a workpiece, and at least one drone for transferring the workpiece among the manufacturing process stations. It is preferable that the manufacturing system includes a detecting station for detecting contamination or corrosion of the at least one drone, and a washing station for washing the at least one drone.
Device for transporting a hollow body comprising a magnetically actuated gripping means
A device for transporting a hollow body provided with a neck which includes a vertically oriented internal wall, the device including at least elements for gripping the hollow body by engaging with the internal wall of the neck, which are mounted on the lower free end of a rod and movably connected thereto, the rod being mounted to be vertically movable between a high position and a low position, wherein the gripping elements are mounted to be radially movable between a retracted position in which the gripping elements are vertically inserted from top to bottom into the neck, without contacting the internal wall, and a deployed position in which the gripping elements engage the internal wall of the neck, and the change in position of the gripping elements from the retracted to the deployed position and/or from the deployed to the retracted position is actuated by a magnetic field.
METHOD AND DEVICE FOR ORIENTING INDIVIDUAL ELEMENTS, IN PARTICULAR FILTER ELEMENTS, DURING THE TRANSFER THEREOF FURTHER PROCESSING
Method for aligning single elements (4) arranged in receiving pockets (3) of a transfer means (2), wherein the receiving pockets (3) are arranged in rows and are moved stepwise from one station into a following station, comprising the following steps: determining in which receiving pockets (3) incorrectly aligned single elements (4) are present, ejecting the single elements (4) determined as incorrectly aligned from the associated receiving pockets (3), turning the ejected single elements (4) by 180, and re-inserting the turned single elements (4) into the associated receiving pockets (3).
Preform conveying apparatus and method
An apparatus and a method for conveying preforms, to a blow molding machine. The apparatus includes a conveying device which conveys preforms away from a supply of preforms, a feeding device that receives preforms from the conveying device, and a sorting device that sorts the preforms and conveys them in a direction of travel. The conveying device ends above the sorting device. The inlet end of the feeding device has a holding zone which the preforms reach as they arrive from the conveying device, and the discharge end of the feeding device has a transfer zone via which the preforms reach the sorting device. The feeding device has an orienting zone with an orienting device designed so that the flow of preforms is oriented in the direction of the flow of the preforms in the sorting device (direction of travel), and the oriented preforms run through the transfer zone.
CUP HOLDER RETAINER INCORPORATING AN INTEGRAL PRELOADED RETAINER CLIP
A cup holder retainer is provided. The cup holder retainer includes a support frame and a preloaded retainer clip. The preloaded retainer clip is connected to the support frame by a living hinge and an integral biasing element that biases the preloaded retainer clip into a cup-engaging position.
Low profile product extractor for thermoformed products
A pressware extractor assembly includes an elongated transport rail, a first car, a second car, and a powered drive mechanism. The first car includes a first car frame and a plurality of extractor elements operable to releasably hold respective products. The second car is slidably supported by the transport rail to slide laterally relative to the transport rail along the lateral rail axis, with the first car being supported to slide laterally with the second car. The powered drive mechanism shiftably supports the first car relative to the second car for vertical movement of the extractor elements relative to the mold assembly. The powered drive mechanism is configured to shift the first car between a lowered position, and a raised position, in which the products are lifted by the extractor elements.
METHOD FOR TRANSFERRING BOTTOM LABELS AND WRAPAROUND LABELS INTO AN INJECTION MOULD AND DEVICE, SUITABLE FOR THIS PURPOSE, FOR PRODUCING INJECTION-MOULDED PARTS PROVIDED WITH BOTTOM LABELS AND WRAPAROUND LABELS
A method is proposed for transferring a bottom label and a wraparound label into an injection mould for producing an injection-moulded part provided with the labels, in that the bottom label is arranged on the end side and the wraparound label on the lateral side of an insert die and the insert die equipped with the two labels is introduced into the mould cavity of the moulding tool, after which the bottom label is deposited on the bottom and the wraparound label on the lateral surface of the mould cavity of the moulding tool, in order to back-mould them with a plastics material injected into the mould cavity. According to the invention, the method comprises the following steps of:providing an insert die, the end side of which has a central portion and a circumferential portion adjoining the central portion radially on the outside, wherein the central portion protrudes further in the direction of the free end of the insert die in the axial direction of the latter than the circumferential portion, such that the cross section of the insert die narrows in the direction of its free end, at least in the circumferential portion of its end side;applying the bottom label both to the central portion and to the circumferential portion of the end side of the insert die and applying the wraparound label to the lateral side thereof such that the wraparound label projects beyond the end, fining the end side, of the lateral side of the insert die in the direction of the free end thereof;introducing the insert die equipped with the two labels into the mould cavity of the moulding tool;detaching the wraparound label from the lateral side of the insert die and applying same at least to the lateral surface of the mould cavity of the moulding tool;detaching the bottom label from the end side of the insert die and applying same to the bottom of the mould cavity of the moulding tool, wherein the peripheral region of the bottom label is turned down from the circumferential portion of the end side of the insert die onto the bottom of the mould cavity of the moulding tool, such that it internally overlaps the edge, facing it, of the wraparound label; andextracting the insert die from the mould cavity of the moulding tool. The invention also relates to an injection-moulding device, suitable for carrying out such a method, having an insert die of the abovementioned type.
