Abstract:
An apparatus for removing carton blanks, erecting and transferring cartons to a conveyor apparatus which includes a magazine for cartons and a rotor with a plurality of radially offstanding suction units. To attain a high output with an apparatus which is simple in structure, the rotor is disposed on a pivotable arm. On each pivoting movement of the rotor during one operating cycle, a carton blank is removed from the magazine while simultaneously formed carton is inserted into the conveyor apparatus at a transfer station. A counterpart suction device, which is associated with a station between the magazine and the transfer station, erects the cartons and breaks them on themselves.
Abstract:
A machine for converting tubular plastic film from flat fold to pleated fold cross section which includes self-contained radio controlled inflating capsule positioned within the tube to inflate it as the gussets are being formed by conventional forming or plowing mechanism.
Abstract:
An automatic case erector and sealer apparatus useful in the erecting of packaging cases, boxes and cartons from flats, utilizing case puncturing and gripping pins, spraying adhesive onto the interior surfaces of the case flaps, while the flaps are in a semi-open position, and sealing the minor and major flaps of the erected flats with compression to thereby secure the major and minor flaps for subsequent filling of the formed case, box or carton with consumer goods.
Abstract:
To maintain an air or gas bubble forming in a moving tube of plastics material between pairs of squeeze rollers, an air or gas injecting needle is mounted to pivot substantially in a plane containing the centerline of the tube. The needle pierces the tube wall of the bubble when in one rotary position, moves with the tube while pivoting through an arc depending on the depth of needle penetration and is withdrawn from the bubble in a second rotary position.
Abstract:
A method and an apparatus for handling and setting up large slit-boxes of the type which is formed by a tubular slit-box blank (6) which is collapsed into a flat two layer blank and which comprises sides (7,8) with connected inner flaps (9) and outer flaps (10) respectively at at least one end of the slit-box. The slit-box is handled in a horizontal position by means of a catcher carriage (16) which is displaceable between a first position over a magazine for slit-box blanks (6) and second position for setting up the slit-box blanks. The carriage has a first set of catchers (17) to catch a first side (8) and its connected outer flaps (10) in the first layer of slit-box blanks and a second set of catchers (20) to catch the second side (7) in the upper layer of the slit-box blank. The said second side (7) is released so that the slit-box by its own weight moves to a more or less open position. The inner flap (9) of the released slit-box side (7) in then introduced into the space between the outer flaps (10). Finally the outer flaps (10) are folded in over the inner flaps (9). The folding in of the said first mentioned inner flap (9) is preferably by means of a crank arm (22) having a horizontal arm portion (24) which both provides a substantially complete straightening up of the container blank into parallelipedical tube form by folding in the inner flap (9) and a retaining of the two inner flaps (9) during a predetermined phase of the folding in of the outer flaps (10) over the inner flaps (9). The apparatus may comprise means for sealing the outer flaps (10) to the inner flaps (9).
Abstract:
Disclosed herein is an apparatus that comprises grasping suction pads designed to grip the bottom blank in a pile and, in cooperation first of all with second grasping suction pads, then with an intermediate arm, and finally with third grasping suction pads, to open the blank while it is held stably in a forming station through the contemporaneous gripping of two lateral walls that are maintained orthogonal by the first and second grasping suction pads. At the forming station, first folding devices attend to the folding of the flaps that define the bottom of the container, subsequently to which a pile of articles is placed inside the container. Once this has been done, second folding devices attend to the folding of the flaps that define the cover of the container. Then with the synchronous movement of two frames, each of which is provided with three of the four folding members belonging both to the first and second folding devices, the transfer of the container takes place towards the movement devices connected to a banding group.
Abstract:
A cartoner for inserting a product into an expanded carton having at least one open end and side flaps and an end panel with tuck flap thereon, and thereafter closing the open end, the cartoner accommodating a wide variety of carton shapes and sizes; a product infeed conveyor for such a cartoner including a product support plate extending laterally from either side of the cartoner and including a conveyor chain carrying product pushers pivotally mounted thereon, the product support plate being positioned from a bottom carton supporting rail a distance to receive the product pushers therethrough so that the product pushers both feed the product to the cartons and insert the product therein.
Abstract:
A packaging machine includes oscillatable feeding means for withdrawing cartons from a hopper in sequence together with pusher means which engages withdrawn cartons and moves the cartons in sequence into cooperative relationship with conveyor means having transversely disposed spaced apart flight bars which move the cartons along a predetermined path so that leading end flaps of transversely disposed open ended cartons are disposed for engagement by static plows and so that a folding arm movable in a horizontal plane and through a clearance notch formed in each leading end flap may engage the immediately preceding trailing end flap so as to impart closing movement thereto. The machine may be readily converted for use with cartons of different sizes by suction means disposed on the oscillatable feeding means and arranged to provide suction pressure during every cycle or during alternate cycles only.
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.
Abstract:
A plurality of collapsed open ended sleeve-type cartons are withdrawn in sequence from a hopper by feeder means which engages a single wall of each carton and moves in such a direction as to cause another wall of the carton to engage fixed cam means having a camming surface disposed at an angle to the general direction of feeding movement of cartons from the hopper so as partially to set up the open ended sleeve-type carton. A carton feeding operation is performed by a main feeding arm to which a supplementary feeder arm is pivotally connected and biased to impart desired pressure to the carton to facilitate setting the carton up during initial stages of a withdrawal operation. After a carton is withdrawn from the hopper, the feeder means moves into cooperative relationship with a carton stripper which insures that the feeder arm disengages the carton and immediately thereafter an oscillatable pusher advances the carton in partially set-up condition into cooperative engagement with a plurality of spaced flight bars which control the movement of the open ended carton while loading of the carton is effected from both ends simultaneously by suitable guides following which carton end closure panels are folded by machine guides into closed positions and subsequently interlocked by locking means which operates in synchronism with the flight bars to complete the package.
