Abstract:
Apparatus for handling and transferring bulb-shaped glass containers from one station in a container production line to another. A series of container handling vacuum chucks are linked together into an endless chain to pick glass containers in succession up from a first conveyor and to deposit the containers on a second conveyor. A control valve mounted on each chuck normally supplies the chuck with vacuum, however the control valve is actuated at the container discharge station, and may also be actuated at a reject station to supply air under pressure to the chuck to eject the container.
Abstract:
Loading and conveying apparatus comprising a conveyor, means to position objects on the conveyor comprising a rotary shaft having a spiral land bounding a spiral groove, and means to load objects onto the conveyor and into the groove in sequence as successive portions of the groove reach the loading means.
Abstract:
An overhead trolley suspends a load carrier which is provided with two pintles spaced apart from each other longitudinally of the load carrier and spaced inwardly from the ends of the load carrier. Accordingly, the center of gravity of a load carried by the load carrier can be located between said pins and an end of the load carrier. The overhead trolley has a supporting surface which receives and supports the pintles. There is an open space above the supporting member above each of the pintles so that each pintle can be lifted off of its supporting surface, whereby an unbalanced load in said load carrier causes the load carrier to tilt so that it is supported by the pintle which is nearest the load center of gravity, thereby reducing the tilting moment of the load carrier in response to an unbalanced load.
Abstract:
The method utilizes a stationary tipping trough including a pair of longitudinally spaced substantially angular supporting surfaces each having a downwardly and inwardly sloping inlet side and an upwardly and outwardly sloping steeper outlet side. A pair of tipping levers are oscillatable by an associated fluid pressure actuator to engage a longitudinal corner edge of a bar in the tipping trough to tilt the bar so that it rests on a different side. A pair of lifters, having projecting fingers, are oscillatable about the same axis as the tilting levers by a different fluid pressure actuator so that the fingers engage the then lower side of a bar in the tipping trough and move the bar over the outlet sides of the supporting surfaces. The tipping trough preferably is arranged between a bar feeding roller conveyor and a bar discharge roller conveyor, and switch means are provided for engagement with a bar moving along the feeding conveyor. The bars have sloping or tapered ends providing respective projecting noses, coplanar with one bar side surface, and the switch means are so arranged that, depending upon which switch is engaged by a projecting nose, an appropriate bar tipping operation is initiated. Alternatively, the switch means may be arranged beneath a bar support surface, again for cooperation with the nose of a bar, or may be arranged to project into the tilting trough for engagement by the nose of a bar.
Abstract:
Apparatus for receiving single or multiple bundles of corrugated board blanks from a corrugator in which the bundles are automatically picked up and in the preferred embodiment stacked on a cart, with alternate bundles being placed upside down with respect to the orientation of their delivery to the mechanism. The disclosed mechanism is capable of handling full, corrugator width, single bundles of board or a plurality of less wide bundles at one time, thus obviating the necessity of having extremely high speed handling equipment or large off-bearer crews to handle the production from a corrugator. The bundles themselves, when stacked on the cart or truck, are placed in striated form for ease of unloading at another position.
Abstract:
A system for conveying automobiles in automatic car washers is illustrated, described and claimed in the patent to Ced F. Brown, U.S. Pat. No. 3,687,083, issued Aug. 29, 1972. The front and rear wheels on one side of the vehicle are driven in a trough by hydraulic units effective on one or the other or both of the wheels. Difficulty was experienced in tracking the wheels within the trough and this was overcome by sloping the trough bottom or by permitting the trough bottom to tilt laterally in either direction. The wheel will climb up from the slope and assume a horizontal position to track on the center line thereof and to come back to the center line each time it moves therefrom.
Abstract:
A group of incoming continuously operating conveyor belts in a first plane are connected to two or more continuously operating connecting loops. The loops are connected to outgoing continuously operating conveyor belts in separate planes. Each loop comprises a continuously operating conveyor belt having a helical section guided over opposite direction rollers and a portion extending downwardly from top to bottom of the helical section. Coupling means connect the loop selectively with the incoming and outgoing conveyor belts.
Abstract:
A conveyor turn including a belt shaped and mounted in a relation forming an upper active run which moves arcuately about a predetermined location, to advance workpieces along a correspondingly arcuate path and thereby change their direction of movement, and forming also a return run desirably spaced beneath and generally parallel to the active run. The belt is preferably driven by an endless drive element which engages a series of coacting parts on the periphery of the belt in driving relation.
Abstract:
This device for feeding, loading and discharging workpieces by loading them rotatably and centerlessly utilizes peripheral holding members of which at least one is movable for performing the loading step and constitutes the lower support of the workpiece, mounted on a movable unit displaceable along an abutment acting as a ramp for lifting the workpieces from a reception position to a loading position; this movable unit acts at the same time as a ramp for lowering the workpieces between its holding members after clearing said feed ramp, the path along which said movable holding member is caused to travel diverging from the path along which the workpieces are discharged by gravity, in order to permit this discharge.
Abstract:
A conveyor link and conveyor comprising substantially the shape of a plate formed with a pair of curved lug projecting from one edge under the plate and with a pair of closed-loop forming straps along the other edge, so that relative engagement of the lugs and straps permits the easy assembling and disassembling of the links. The shape of the plate is such as to permit a lateral swivel movement of the adjacent links in a chain constructed by using these links.
