Abstract:
A device is disclosed which grips and transfers articles from one conveyor to another conveyor or to containers on another conveyor. The incoming conveyed articles are sensed and the drive mechanism of an overhead vacuum conveyor which grips and transfers the articles is adjusted automatically to align a gripper with an article.
Abstract:
A conveyor having a belt capable of following a curved path is mounted on a carriage having a central attachment to a conveyor chain and lateral attachments to a pair of side stabilizers. The conveyor operates on a track assembly having a central slide surface for contact with the chain and lateral stabilizer operating surfaces for contact with the stabilizers when they are in use. The stabilizers may be slightly elevated from their operating surfaces during normal conveyor operation with a balanced load on the belt, only touching the operating surfaces when the load becomes unbalanced. The track assembly is preferably in the cross-sectional shape of an I-beam with the conveyor operating on the flanges of the beam. Beam sections in regular geometric shapes such as vertical curves, horizontal curves, and straight sections are joined together in approximate alignment to form the desired conveyor path, and the slide surfaces are then shimmed into closer alignment if necessary. Each section may be prefabricated with appropriate mounting holes for the slide surface, lubricant injection holes, and drop out holes punched in a predetermined pattern in the beam flanges.
Abstract:
A belt for large round baler has a roughly textured, crop-engaging surface formed by a plurality of continuous, uniform height walls defining a plurality of recesses therebetween. The walls may be arranged in a variety of polygonal shapes. The height of the walls is less than the maximum spacing between adjacent walls. The thickness of the walls decrease from the base toward the tip. The textured surface of the belt provides reduced levels of noise and dust, a self-cleaning action, lateral stiffness and longitudinal flexibility.
Abstract:
Transportation apparatus comprising two parallel chains extending in the transport direction. Workpiece carriers are disposed between the chains and extend parallel to each other. Each workpiece carrier includes two support elements extending parallel to each other and are rigidly connected together. On each workpiece carrier, a plurality of workpiece clamps are disposed. Each workpiece clamp comprises two clamp members, respectively connected to the support elements. At least one clamp member of each workpiece clamp is pivotal about the support element with which it is connected, between a closed position and an open position. The chains are fed between a charging station, at which the workpiece clamps are changed with workpieces, and a discharge station at which the workpieces are released from the clamps.
Abstract:
The invention relates to apparatus for conveying insulating glass panes which are slightly inclined from the vertical and have edge grooves filled with a sealing compound. Pairs of mutually opposite supports are provided, which are moved in the direction of conveyance and have substantially horizontal supporting surfaces and engage the lower edge face of each of the individual glass panes of each insulating glass pane only in an outer portion of the lower edge face. Backing rollers are provided, which are freely rotatably mounted on substantially vertical axes and adapted to engage the insulating glass pane only close to its upper edge.
Abstract:
A system for handling axial lead components comprises a flexible metal tape or molded plastic strip (to electrically test components while on strip), that has been especially perforated by die punching to have a plurality of sprocket receiving holes along its edges and a plurality of component receiving holes spaced centrally and along the length of the tape. The component holes have tabs at each lateral end thereof that define a component lead receiving slot. The slot has a predefined width at the end away from the tape. The slot width increases toward the base of the tabs. The predefined width of the slot at the end away from the tape is smaller than the diameter of the lead to be received in the slot. Only by flexing the tape to spread the tabs can a lead be inserted, freely rotated or removed from the slot. At least one tape flexing station is associated with each system. The tape flexing station comprises a cylindrical surface of sufficiently small radius of curvature at one position such that the tape pulled over the surface will be sufficiently flexed to spread the tabs to open the slots enabling a lead to be moved therein. Associated with every flexing station is at least one driving hold down that pulls the tape over the cylindrical surface and advances the tape by engaging the sprocket receiving holes.
Abstract:
A mechanism for cooling molded bodies such as green carbon anodes including a disk shaped concave receiving transfer means which receives the bodies and either rejects them or transfers them to individual support stations on a cooling conveyor which carries them through a cooling zone, and delivers them to a discharge transfer means which either accepts or rejects the anodes, and the transfer means is selectively pivotal about either lateral edge to accept or reject the anodes.
Abstract:
A multi-section conveyor is assembled from at least one power driven section and a plurality of non-powered sections that derive operating power from the powered section through a coupler linking the sections in tandem. The conveyor sections each have opposite end rollers with a central roller core carrying a diametric cross-pin. The coupler between each pair of sections consists of a pair of shafts linked to transmit the rotation of one shaft to the other, and each shaft is receivable within one of the roller cores. The shaft end so receivable is slotted to engage the cross-pin and thus becomes locked into rotation with the roller. One of the shafts may extend relatively further than the other for initial engagement of the coupler with one roller at a time, and the shaft diameter of one or both shafts may be reduced adjacent to the axial position of the slot where the cross-pin will be located after the coupler is fully engaged with both rollers to provide dynamic locking of the coupler to the joined conveyor sections during conveyor operation.
Abstract:
A loading table including a stable frame with a flat depositing plane (13) for shells (14) lying beside each other and feeding means for removing the shells, one at a time, from the plane, through lateral displacement. The feeding means utilize holding trough segments arranged in an endless chain with two stories of which the upper story comes into connection with the depositing plane. The segments are fastened in the links (16) of two drive chains which by means of the step drive mechanism can be actuated so that at a certain actuation of the step drive mechanism, holding troughs (15) for the shells, which can be composed of holding trough segments in the upper story, are moved forwards one spacing distance. The pairs of holding trough segments are arranged in such a way that said holding troughs which are formed are capable of receiving new shells directly from above under parallel displacement substantially at right angles to the depositing plane in a number corresponding to the number of shells removed from the plane. The holding troughs can then receive two or more shells simultaneously when these are arranged parallel to each other.
Abstract:
A low damage beet cleaner and elevator for a beet harvester is described. Beets are lifted elevationally between a lugged, endless elevator draper and an endless, upwardly inclined belt having flexible, finger-like projections. The draper and the belt are driven through their respective circuits with the belt being driven at a speed faster than that of the draper. The speed differential between the belt and the draper causes the finger-like projections to flexibly engage with the beets producing a brushing effect on the beets to clean them while they are being elevated for loading.
