1,052,109. Bundling-apparatus. IZHORSKY ZAVOD IM. ZHDANOVA. April 28, 1964. No. 17509/64. Heading B8C. A device for stacking lengths of rolled stock, e.g. angle-iron, prior to bundling by binding includes a feeding mechanism for transferring one or more lengths from an approach conveyer towards vertically movable supports, and stacking means in the form of one or more elongated members reciprocable across the supports; the feeding mechanism transferring the lengths on to the stacking means which moves across the supports carrying the lengths until they abut a stop, the stacking means continuing its movement so as to strip the lengths on to the supports and returning to rest above the last laid lengths. The machine shown consists of stack supports 2 on both sides of a line of driven rollers 3, a stack being formed alternatively first on one and then on the other set of supports. Lengths are delivered by one of approach conveyers 1 to the rollers 3 to abut one of the stops 7 raised according to stack length. An induction pick-off 17 stops the rollers and starts chain conveyers 5 which feed the lengths on to the respective stacking means consisting of plates 6 hinged to carriages 10 and reciprocating in guides 11. Sensing means 18 cause stoppage of the conveyers 5 and engagement of the drive of the plates 6 which carry the lengths against stops and continue their movement from under the lengths dropping them on to the support 2 which is then lowered. The lowering of the support, stopping and return of the means 6 are controlled by a photoelectric means 19 operated by the lengths. Rollers 15 raise the plates 6 during their return to their initial position above the supports 2. Two sets 8, 9 of stops are provided, the former fixed, and the latter movable at alternate stacking operations to a position slightly in advance of the stops 8 so that alternate lengths of stock may be staggered in relation to those below. Repetition of the operation is controlled by means 20 (not detailed) until a stack of predetermined height is formed, when a limit switch 21 reverses the travel of conveyers 5. A second stack is then formed on the other supports 2 while the first stack is bundled (no details given). Several aligned stacks of short lengths may be formed simultaneously.
