Also disclosed is a method of feeding a flow of container bodies as with the above-captioned apparatus.
Abstract:
A manually operated tool has a spaced parallel pair of elongated flange members mounted on the jaws at the ends of two horizontally disposed tongs or calipers. Each of a pair of hand hold members is individually associated with a corresponding one of the tongs. Grip levers adjacent the hand holds selectively open or close the tongs and, therefore, move the flanges apart or together. The flanges may be placed over a row of substantially aligned necks of a row of bottles, even if some of the bottles are slightly misaligned. The grip levers are pulled to close the tongs and bring the flanges together, thereby gripping the necks of the bottles. To release the bottles, the grip levers are released. The flanges move apart under a spring bias to release the bottles. If more or fewer bottles are to be picked up, longer or shorter flanges may be substituted for each other. Also, since there is no position on the flanges which is dedicated to picking up a bottle, any suitable number of bottles may be accommodated at any positions along the length of the flange.
Abstract:
An easily replaceable collet assembly for use in a movable pallet containing a plurality of stations for releasably gripping and rotating a plurality of resin preforms as they are moved through a blow molding process for providing rapid reconfiguration of the stations to accept different sized preforms. There is a mounting member carried by the pallet for rotation, the mounting member comprising a mounting plate perpendicular to a rotatable shaft connecting it to the pallet; a locking member carried by the mounting member for rotation about the shaft; and, a collet member for releasably gripping a preform of a given size, the collet member including locking apparatus for interacting with the locking member to releasably attach the collet member to the mounting plate to be moved in combination therewith.
Abstract:
A holding device for gripping and retaining containers, including can bodies or cans which have one open end, during transport on conveyers, includes a planar carrier which can be connected at the conveyer chain or forms part thereof. A plurality of clamp elements is secured at the carrier. The clamp elements are made of resilient material, and they are fastened for clamping or snap-like retention of the container bodies at diametrically opposite locations respectively in pairs at the carrier. The clamp elements of each pair have respectively crossing adjacent sections, and the inner clamp is adapted to operatively contact the peripheral edge of the respective retained container. The outer clamp is adapted to operatively engage the outer wall surface of the container rim which is directed towards the carrier.
Abstract:
A coupling includes an outer cup-shaped member which acts as a support for other portions of the coupling and which itself is revolvably supported on a conveyor that moves the coupling between workpiece loading and unloading stations. The outer cup-shaped member acts as a shield against ambient conditions which may include heating, coating or other processing means. One embodiment of the invention has a plurality of fingers mounted to move radially inward of the coupling to grasp the workpiece, which fingers are mounted to form a part of the outer shield or wall at the time that they are grasping a workpiece. Another embodiment of the invention involves an internal chuck sort of coupling using an expandable elastomeric member which can expand outwardly into a grasping relationship with a hollow portion of the workpiece. The coupling and conveyor are suited for use in handling soft or easily marked materials such as plastic, soft metals and the like.
Abstract:
A coupling includes an outer cup-shaped member that acts as a support for other parts and is both revolvably and slidably supported on a conveyor that moves the coupling between work stations. In the normal installation, the coupling would move between workpiece loading and unloading stations. Slide motion relative to the conveyor is used to engage and disengage a workpiece. The outer cup-shaped member acts as a shield against ambient conditions which may include heating, coating or the like. The coupling preferably involves an internal chuck feature having an expandable resilient detent member preferably in the form of a metallic stretchable annular member known as a garter spring. The coupling and conveyor are suited for use in handling soft or easily marked materials such as plastic.
Abstract:
A manually operated four bar linkage on a conveying device permits manual removal of preforms or other workpieces when they have not been ejected from the device at the desired unloading station. The linkage device has a cam track located adjacent to the return path of an endless type conveyor. The cam track is manually brought into conjunction with the couplings or collets which have accidentally retained a preform to force the coupling mechanism to move to a release position thus enabling manual removal of the preform. Preferably a bar or similar knock-out device is located downstream of the point where the cam track engages the coupling to ensure that all such preforms or other workpieces are removed.
Abstract:
Apparatus for applying carrier grids to the tops of groups of a predetermined number of capped containers, comprising a conveyor for moving the containers standing upright thereon along a predetermined horizontal path, a pocket wheel arranged adjacent the conveyor in the path of movement of the containers rotable by movement of the containers therealong, a pair of spaced parallel chains supported above the conveyor along the path of movement of the containers in an inclined position with one end above the tops of the containers and the other end below the tops for progressively applying pressure to a grid deposited on the tops of the containers, a hopper for holding a stack of grids, an ejector for ejecting the lowermost grid in the hopper downwardly at an angle directly into the path of movement of the tops of the containers, and means operable by the counter to effect operation of the ejector when the counter has counted a number of containers corresponding to the number of containers the grid is designed to hold.
Abstract:
A continuous belt conveyor for transporting bottles to be processed includes an inclined ramp portion for elevating bottles to a moving horizontal platform portion, screw means for selectively adjusting the height of the moving horizontal platform portion without varying the length or tension of the conveyor belt, a variable pitch horizontally disposed screw guide for uniformly spacing bottles as they enter upon the moving horizontal platform, and a plurality of uniformly spaced neck gripping overhead bottle carriers mounted on a continous overhead chain moving in synchronism with the conveyor belt, with overhead cam means adjacent to the junction between the inclined ramp portion and the horizontal platform portion of the conveyor belt for causing the overhead bottle grippers to be successively elevated over, aligned with, and then lowered onto neck locking engagement with individual bottles passing therebeneath. The overhead bottle grippers comprise a clam shell type of structure opened when elevated and closed when lowered and a surrounding rotatable cylindrical shield which holds the clam shells in locked position when lowered thereover and which also by engagement with a suitable rack produces a rotation of the bottles as they are carried thereby through a spray processing station. A synchronous drive mechanism including a feedback loop between the conveyor belt and the overhead chain conveyor maintains constant speed and physical relationship between the two continuously moving conveyor means.
