Abstract:
There are depicted, described and claimed an apparatus and method for receiving and transporting tray blanks of corrugated cardboard. Cutouts provide means for bending of flap portions of the blank which form the outer retaining walls or members. Asjustment is provided for the frame support and for the size of the tray as to its width, length and sidewall height. The tray blanks are advanced forwardly to and into a hopper where the lowermost tray blank is withdrawn from a stacked array by a plurality of vacuum cups carried by and on arms. The tray is erected on a reciprocably-moved table by apparatus whereat the back edge portion is brought to a normal position, then the partially erected tray is filled with containers brought by conveyors and said containers are inserted by pushers. The forward end of the tray is brought to a substantially vertical condition by Y-fingers. The rear inner side flaps are moved to a position against the containers by pivoted finger mechanism. This pivoted mechanism is actuated by a pneumatic cylinder which moves a block and the pivoted finger mechanism forwardly at a greater speed than the reciprocated table. The forward inner flaps of the tray blank are also turned inwardly by plows mounted to the frame. The outer flaps are lifted so as to close the sides of the tray and by hot-melt adhesive the ends are secured with pushers positioning and retaining the flaps until the adhesive is set.
Abstract:
A conveying system for bailed containers receives said containers after bail-application and with the bails supported in a substantially vertical manner advances the containers to and through a turning station. The container is first detected as to its presence on a conveyor belt and then by electric eye means a spot on the container is "read". If the spot is on the desired side no turning is performed but if the spot is detected on the opposite side the container is turned by raising a turning rail that engages the bottom rim of a container and causes the container to turn a half revolution. During turning the bail is maintained in an upright position by a magnet bar. The conveyors also may deliver bailed containers to a merge and stop unit having flow control means for delivering these containers in timed array to further processing, such as packaging.
Abstract:
An improved apparatus for separating and feeding a preformed container fron a nested stack, said apparatus adapted for accepting a nested stack of containers in a vertical array, tilting the nested stack to a horizontal array by means of a tilting carriage assembly (34), advancing the horizontal stack (170) on an advancing portion (36), stopping the nested stack at a preferred position and immediately lifing the nested stack from the advancing portion (36) by means of an elongated rail assembly 96. A separating assembly (38) separates a first container from the nested stack, said first container advances to a pivoting hook assembly (40) where the first container is oriented from a substantially horizontal array to a substantially vertical array, and a stabilizer assembly (42) steadies the horizontal container for transfer to subsequent machinery.
Abstract:
This invention discloses an apparatus and method for receiving small containers and articles in a determined array and from a single side accumulating and feeding these containers or articles in a series of loading moves into the end of an erected carton. In the embodiments shown, provision is made for a carton size change within determined limits. These case packing apparatus assemblies shown are for packing small containers such as quart or pint paint containers and in an alternate arrangement for packing a multiplicity of sponges. Automatically actuated fingers that engage the lower extent or surface of folded cartons and then move into slots to engage upper flaps or carton extents are also shown.
Abstract:
An automatically operated feeding and reorienting apparatus for vertically oriented stacks of nested preformed containers including a continuously advancing infeed conveyor 10 for advancing individual vertical stacks of nested containers to a transfer means assembly 12, whereat a single stack of containers 84A is separated and transferred to a tilting carriage assembly 14, whereupon the nested stack is reoriented by tilting to a substantially horizontal disposition, upon completion of said reorientation the now horizontally oriented stack of containers is advanced onto a denesting conveyor assembly 16 by a stack advancing assembly 66.
Abstract:
This invention pertains to pins carried by and in a retainer head member with the pins actuated when and as the head member and an associated contact member reaches the outermost portion of a paperboard member whereat the pins are caused to move obliquely to this surface and penetrate the paperboard sufficiently to engage and retain the paperboard. These pin ends by latch members are maintained in the desired penetrating position during transfer. This latch is actuated to release the projected pins when transfer is completed. The paperboard is conventionally of corrugated paperboard construction and the extent of pin end protrusion is carefully controlled so that the pin ends in the penetrating position do not protrude and penetrate the rear panel or wall of the paperboard so that only one penetrated paperboard member is transferred. The embodiments shown are adapted for use with paperboard which is not supple or flexible as is cloth or leather. The contacting member is disposed to establish and engage the outer surface of the paperboard member and the latch member is automatic in its operation during penetration and transfer. The latch is actuated to an open and release condition at the end of the transfer motion.
Abstract:
This invention pertains to a container actuated converging apparatus wherein bailed containers in random order are delivered from one or two bail-applying mechanisms in oriented condition with their bails slidably retained in bail guides. These bailed containers are advanced to a converging mechanism where apparatus is provided to insure that only one container at a time is fed from these plural conveyors to a single conveyor. This converging apparatus is so arranged and disposed that it will accept and pass a stream of containers from either of the conveyors to the single conveyor when the other conveyor is empty of containers.
Abstract:
An upstacker jaw clamp and palletizer apparatus in which containers are fed one at a time to an upstacker station and an elevating platform whereat these containers are lifted and at the extreme lift are retained by opposed jaw clamps. These jaw clamps are moved substantially simultaneously to and from retaining condition in response to electronic control signals. The jaw clamps carry pins that are reciprocably retained in bores with forward movement provided by a bias. When a round metal container is palletized, each jaw clamp has two substantially alike pins with blunted forward ends. When the container is plastic with a contoured bottom, the pins are threaded and retain a contoured member. No matter the container shape, the jaw, when moved forwardly, causes the lip portion to move under the elevated container with the pin ends, the contoured member, or the plate disposed immediately above the lip portion and biased forwardly to engage the side walls of the container. The jaws, when moved outwardly for upstacking the immediately-below container, utilize the forwardly-biased pins which continue to engage the side walls of the container as the lip portion is withdrawn. The ends of the biased pins and contoured member provide a centering action. Further withdrawal of the jaw clamp enables the immediately-below container to be moved into position with inertia employed to minimize the drop of the above container during upstacking.

Abstract:
An apparatus and method is disclosed for improvements in the receiving of folded cartons in a vertical manner and in a storage chute having a beam transport and reciprocating this beam in such a controlled manner so that on the forward stroke this beam is lifted to advance the cartons at a selected rate. From this horizontal chute and the reciprocated beam the cartons are delivered to a relatively horizontal delivery chute from which they are drawn one-at-a-time for erecting. Positive carton edge engagement and release is provided in a novel escapement means so that irregularly made cartons can be accommodated for delivery at a regular rate. This novel escapement insures that only one carton is engaged and pulled from the chute when engaged by the vacuum cups on the swinging suction arm of the erecting station. To insure that an adequate vacuum is present at the occasion of the initial pressing of the suction cups to the lowermost carton there is provided a vacuum assist which is terminated automatically when a determined level of vacuum in the suction system is reached.
