摘要:
An end loaded carton for a plurality of cans includes foldably joined top, bottom and side walls forming a tubular structure and having end closure panels, one wall of the carton being of double ply construction having inner and outer panels, at least one thickening panel foldably joined to the inner ply and being folded into flat face contacting relation with the inner ply to form a three ply wall in engagement with the can ends.

A reuseable open top case having interconnected bottom, side and end walls is provided with a disposable overwrap which includes panels overlying the open top, side, end and bottom walls.

A basket style carton is set up by a machine which imparts inward movement to one end wall so as to allow the adjacent locking tab to clear the associated end notch. A first pusher engages the bottom wall and allows the notch to receive the locking tab. Continued inward movement imparted to the one carton end wall causes the locking tab at the opposite end of the bottom wall to clear the associated notch. A second pusher then depresses the bottom wall and allows the associated locking tab to clear the associated notch.

A carton having a collapsed bottom wall is erected by a machine which engages opposed side walls and draws these walls apart. Simultaneously the side walls are separated by movement in a transverse direction and the bottom wall panels are interlocked.

A carton loading machine is effective to load bottles packaged in basket style or in sleeve style cartons at high speed and with minimal attention by the operator due to the dual function of many of the machine parts.
摘要:
A machine for sequentially withdrawing collapsed sleeve type end loading cartons having face contacting panels in one of which panels an aperture is formed and for initiating set up of the carton into open ended condition, the machine comprising a carton pick up device for sequentially engaging and withdrawing collapsed cartons from the hopper, and an elongated support rod on which the carton pick up device is slidably mounted, the support rod being arranged so that one end thereof extends through the aperture in one of the carton panels and into engagement with the other face contacting panel so as to initiate a set up condition of the carton in coordination with sliding movement of the carton pick up device relative to the elongated support rod.
摘要:
A support slidably mounted for reciprocable movement above and generally parallel to a conveyor, a rotator element mounted on and movable with the support and having a generally U-shaped package enveloping device arranged to straddle the package to be rotated together with a rotatable driving device mounted on and movable with the support for imparting rotary movement to the rotator element.

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.
摘要:
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.
摘要:
A method for withdrawing from a hopper collapsed sleeve type end loading cartons having face contacting panels in one of which panels a pair of apertures are formed and for initiating set up of the carton into open ended condition, the method comprising sequentially engaging and withdrawing collapsed cartons from the hopper with pick up devices slidably mounted on a pair of support rods, arranged so that one end of each support rod extends through one aperture in one of the face contacting carton panels and into engagement with the other face contacting panel so as to initiate a set up condition of the carton.
