Abstract:
An improved wheel and bearing assembly for a load transporting overhead trolley with a load support bracket having opposed stems mounting laterally offset wheels in rolling engagement with an overhead track has wheel-incorporated radially inner and outer race members with anti-friction load bearing balls between them in an annular trackway. The radially inner race member is split offset from the line connecting the center of the balls and formed of mating laterally outer and laterally inner abutting members which have laterally mating non-compressible radially abutting surfaces with radially aligned annular grooves therein. A circumferentially compressible retention spring is carried in one of the annular grooves and resiliently projects radially from the groove so that a snap fit is achieved when the inner race members are moved relatively laterally into mating assembly.
Abstract:
A chain for use in transmission and transportation with low friction, less wear, and low noises. The chain has central portions directly in engagement with a sprocket tooth face. Each of a number of pins is supported by rolling bearings attached individually to one of inside link plates and outside link plates, and plain bearings attached to the other link plates. With this arrangement, the sprocket tooth face and pin tooth face are brought into rolling contact with one another, and the link plates bend relatively to one another as the pins rotate in rolling contact. Also, the size and weight of the chain are reduced. Since the entire amount of friction and wear are small, power loss and elongation are reduced to thereby preserve a high accuracy of the chain.
Abstract:
A spiral overlay having multiple variations, but generically, comprised of wire spirals intermeshed together by connecting rods extending across the conveyor in the transverse direction. Broadly, a first overlay is made up of spirals which may be tapered and afford pitch control by incorporating elongated loops in the spirals to limit the movement of the rods therein. The elongated loops also provide for collapsibility of the spirals relative to one another. A second overlay is made of integral or modular spirals such that the overlay includes upstanding spiral elements on its conveying surface to provide traction and separation of the articles being conveyed.
Abstract:
Weld-free belt assembly in which elongated link modules are coupled in widthwise side-by-side relationship by transversely-oriented coupling modules. An internal cavity is defined within each link along with a surface configuration on each side of the link which defines an entry access portion for a coupler and slot portions for enabling relative longitudinal movement of the coupler while retaining the coupler within the internal cavity. The interfitting coaction of the links and couplers enables an assembled belt to move from linear planar travel into a curved path to establish an endless-belt configuration. The relative movement of couplers within a link cavity enables longitudinal collection of links along the inner circumference when the belt enters a curvilinear travel path in approximately the same plane and enables re-extension for return to linear travel. An assembled belt can be driven longitudinally by sprockets; and, also, can be driven along a serpentine path by lateral-edge dynamic frictional drive, or in a similarly driven layered helical-path "carousel" arrangement. Special configuration lateral-edge links provide protrusion-free lateral edge surfaces enabling smooth dynamic frictional drive along inner circumference surfaces during curvilinear travel.
Abstract:
An article sorting method and a system to perform the method, in which a plurality of articles having different sorting destinations are sorted out in a highly efficient manner by one carriage. The article sorting system includes a carriage (3) movable along a track (5). This carriage has on it a plurality of conveying mechanisms (13a, 13b, 13c and 13d) which are provided on the carriage (3). On these conveying mechanisms, articles (11) can be placed. A control device (23) controls the operations of the plurality of conveying mechanisms (13a, 13b, 13c and 13d) independently of one another. The control device drives the conveying mechanisms (13a, 13b, 13c and 13d) individually according to the sorting destination data of the articles, so that a single or plural articles (11) are sorted out by the individual operations or combined operations of the driving mechanisms (15a, 15b, 15c and 15d).
Abstract:
An apparatus for conveying poultry along a processing line for deboning. The apparatus includes a number of poultry mounts connected to each other using a chain of cooperative links to form a continuous conveyor. The pivotal junctures between each of the cooperative links are configured so as to provide both lateral and vertical flexibility, allowing the conveyor to be positioned along curves and inclines. Each of the links has a linking post extending from one side and a pair of linking arms extending from the opposite side. The linking arms are spaced apart to receive the linking post of an adjacent link. The links are connected by pins which extend through apertures in the linking arms and through a bore in the linking post of the adjacent link. The diameter of the bore in the linking post is larger than that of the pin, so that the connection is flexible laterally. Each of the poultry mounts includes a base block which is stabilized by laterally extending flanges positioned to slide along guide channels in guide members extending along the conveyor frame. Additionally, each mount includes a freely rotatable upper member for holding the poultry carcasses on the mount, so that a worker carving the poultry may easily access all sides of the poultry carcass without repositioning the carcass upon the mount.
Abstract:
A system and a method for sorting are provided for distributing articles, such as mail pieces or other flats, to predetermined destinations. At the destination, the particular article is raked by a raking assembly from a carrier for placement into a container. The container, when full, is gravity fed onto a discharge conveyor and automatically replaced with a new empty container. The carrier operates on two levels for delivery of articles to containers on two levels while maintaining the carriers in a horizontal position throughout the sorting process. A sloped front end of the carrier allows the articles to be transported at a rapid speed and in a continuous fashion.
Abstract:
The invention relates to an arrangement for the transport of circuit boards (7), such as printed circuit boards or substrates, along a transport path between and/or in the various work stations during assembly, the circuit boards being manipulated in a well-defined position, which arrangement comprises a conveyor chain (3) carrying holding devices (3d) for individual circuit boards (7), which holding devices are spaced apart at distances equal to a plurality of chain links (3c), and transport strip portions (7b) of board material provided on and separable from the circuit boards (7), which strip portions have no circuit function and can be held by the holding devices (3d) for transport by way of the moving conveyor chain (3).
Abstract:
A method and apparatus enable horizontally transporting a succession of objects, such as glass bottles, without bottom support and yet maintaining precise, consistent centerline location. A pair of continuous transport belts are supported, preferably by a pair of complimentary interlocking belts, to maintain a substantially constant distance between the facing object-supporting surfaces. Preferably, the interlocking belts are made of alternating teeth and grooves transverse to the horizontal transfer path. The belts are rendered substantially inextensible transverse to the direction of the path.
Abstract:
First and second shafts are held on first and second guides and a belt is wrapped on the first and second shafts. A motor is mounted on the first guide and rotationally drives a belt. The belt has a surface inclined from its opposite-side edges downward toward its middle to define a recess at the middle of the belt along a conveying direction of the belt. The lead frame is so conveyed that only its opposite-side edges as viewed along the conveying direction of the lead frame are contacted with the surface of the belt and that a bed and leads placed at the middle portion of the lead frame are not contacted with the surface of the belt.
