  • Speed of assembly is vitally important in the manufacture of assembled chain since the cost of the relatively complex machinery for assembling the chain is quite high, and any increased production which can be obtained from a machine has the effect of reducing the machinery cost for a given length of chain.
  • the speed of the conventional, prior art chain assembly machines is essentially limited by the necessity of moving the links intermittently to the pins, and stopping the links at the pins for assembly. Frequently, it is necessary or desirable to lock or clamp the movable member, after it has stopped, relative to the stationary member to assure proper alignment of the chain elements prior to assembly. It can be appreciated that the locking and unlocking of the two members, which must take place when the movable member is stopped, increases the time the movable member is stopped to further limit the rate of assembly of the chain.
  • Another problem with the intermittent motion type of chain assembly machine is the high level of noise generated by the operation thereof.
  • Each abrupt start and stop of the movable member, and each clamping and unclamping of the members, contributes to the severity of the din produced by the operation of the machine.
  • the assembly machine of the present invention does not move one or more elements relative to other elements by an intermittent motion for assembly of the elements but, instead, moves all the elements to be assembled continuously on an endless member.
  • the actuating members which straddle the elements to be assembled and press them into assembled relation, also move continuously and in unison with the members to be assembled.
  • a generally cylindrical carrier continuously rotating about a horizontal axis during operation, has a nest wheel with an endless array of peripheral pockets which receive the elements of, for example, a chain from a chute or chutes at an entry point, as the pockets pass continuously under the chutes.
  • an endless circular array of back-up rams, or pressure members (one for each pitch axis of the chain) is slidably received in the nest wheel for sequential actuation axially relative to the nest wheel by two independent circular stationary cams.
  • the back-up rams in partially advanced positions, define the outer boundaries of the pockets in which one of the outer side bar links of the chain is received.
  • An alignment rod drum on the carrieron one side of the nest wheel continuously rotates in unison with the nest wheel and carries an endless array of rams with alignment rods (one for each pitch axis of the chain) which are slidably received in the back-up rams.
  • the alignment rod rams engage a circular stationary cam for sequential movement of the alignment rods through the back-up rams and into the elements to be assembled for alignment thereof.
  • a drive ram drum on the carrier rotates continuously in unison with the nest wheel.
  • the drive ram drum carries an endless, circular, array of rams with rods, or pressure members, mounted thereon (one for each pitch axes of the chain).
  • the rams are sequentially actuated to press the chain-elements against the back-up ram and into partial assembled relationship, forcing the alignment rods from the elements.
  • the alignment rod rams advance to engage and advance the backup rams to complete assembly of the chain elements. After assembly, the assembled chain is stripped from the nest wheel at a discharge point.
  • the elements of the product, such as a chain, to be assembled are continuously supplied to pockets on a rotating carrier at an entry point and are aligned and assembled in the pockets as the pockets continuously move without stopping toward a discharge point.
  • This is possible by virtue of the endless array of operating members (drive rams, back-up rams, and alignment rods) on the carrier which move in unison with said carrier and are operated sequentially as they move between the entry point and the discharge point.
  • the endless array of actuating members, and the sequential actuation thereof permit operation on several products, or on several segments of a product, at the same time. Between the entry point and the discharge point, different segments of, for example, a chain are simultaneously undergoing different operations so that a continuous supply of in-process products or segments is continuously moving, in various stages of completion, from the entry point to the discharge point.
