  • Patent number: 4957753
    Abstract: A technique is described by which a predetermined amount by weight of ground coffee can be packaged into a container while the coffee density may vary within a range. The amount of ground coffee is supplied into a container along a feed path to fill the container and form a column that extends above the upper rim of the container. The ground coffee is compressed to a predetermined head level by compressing a region around the feed path while leaving a small column of uncompressed coffee. In another embodiment, the volume of the container is expanded during compression by outwardly deforming a container end. This enables the stiffening of the ground coffee to support a smooth unbeaded outer wall after vacuum packing without paneling effects.

  • Patent number: 4884386
    Abstract: A system for recovering, selecting and recycling empty containers returned after use which includes two specific sequences. In the first sequence, a container (4) passes a door (2) to remove material of a different type, while the accepted product activates a microswitch (9) for counting and activating a warming device to blow in hot air onto the same material which is thus softened; the container is then pushed between a motor driven heated pressing roll (18) with tension supplied by sliding contacts (22) to carry out a compact and permanent pressing by using pressing-welding points and another inertia roller (19). Knives (24) cooperate with the two rollers to ensure the separation. In the second sequence or selection phase, recovered bodies (29), are applied from hopper (30) and fall onto a feeding system with vibrating canals, to maintain the containers individually; photocells (34) check that no superpositions occur.

  • Patent number: 4879862
    Abstract: In the process of packaging letter envelopes and mailing wallets, the packaging batch is counted in the end region of the production machine, and the individual article of the packaging batch corresponding to the specific batch size is at least identified or optionally pushed a certain distance sideways out of the path of movement of the packaging batch in one direction or the other as a counting article. The packaging batch is deposited on a conveyor belt and conveyed away. A stack support keeps the stack approximately vertical on its end face. The stack support is advanced in front of the stack at the conveying speed of the conveyor belt. As soon as the counting article at the end of a stack has arrived at a transfer point which is at a relatively long distance from the production machine, a separating device is introduced into the stack, with the result that the following portion of the packaging batch is temporarily halted.

  • Patent number: 4873813
    Abstract: An apparatus and method by which a single operator, at a single station, can pack pre-counted slugs of flat folded cartons, or trays, in one or more layers, in corrugated cases for discharge to a case taper several times faster than with manual packing by several operators. The "flats" are advanced in a longitudinal path on a secondary apron of a stacker, erect on one edge, pre-counted and divided into slugs, so that the single operator can slide each slug longitudinally past a one-way back stop onto a transfer table. The slug may be turned on its longitudinal axis by the operator for inspection and then compressed longitudinally by a ram against the back stop. The operator has already been presented with a single, flat, tubular case, from a stack of such cases, with the leading flaps folded back, and has manually erected the case and inserted it in a case gripper preferably poised above the table, thereby closing the minor bottom closure flaps.

  • Patent number: 4848222
    Abstract: A process for the transportation and subsequent final compression of, for example, synthetic fiber material from rough filling presses to a central press utilizes thin-walled filling bins for the initial precompression. In the rough presses, the fiber material is deposited into the thin-walled filling bins, the filling bins are then transported to the central press, transferred at that location one after the other into the compressing position of the central press, thereafter an additional compression bin is placed over the filling bin in such a way that the walls of the filling bin are in close contact with the inner surface of the walls of the compression bin, and finally the final compression step is performed. With a final compacting pressure being maintained unchanged, the filling bin as well as the walls of the compression bin are pulled off in the upward direction in order to make it possible to package and reinforce the finished bale.

  • Patent number: 4756141
    Abstract: A machine for conditioning a stack of pads, such as sanitary pads, for packaging includes a rotor. Radially extending chambers having closed sides and open front and rear ends are fastened to the rotor. There is a compressor plunger in each chamber. The plungers are carried on guide rods extending from cam follower brackets. A stationary cam plate is mounted perpendicular to the rotational axis of the rotor. The follower rollers are spring biased into contact with the periphery of the cam plate. The chambers are incremented in angular steps starting with a position in which the chamber is stopped momentarily for being loaded with a stack of pads at which time its plunger is retracted. As the loaded chamber increments in two angular steps to an unloading position, the plunger is driven out by the cam to compress the stack. When the chamber rotates from loading position to unloading position, the pads are effectively turned so they are standing on their edges in the unloading position.

    Abstract: The present invention is directed to a method and apparatus for packing tubular bags into boxes by machinery. The tubular bags to be packed are conveyed over various conveyor belts to a positioning belt and from the positioning belt to a positioning table. Layers of tubular bags are then moved onto a rake-like main base that is lowered in a stepwise fashion to receive consecutive layers of tubular bags. When the desired number of tubular bag layers is positioned on the main base, the main base is lowered to deposit the tubular bags onto an intermediate base which together with side walls makes up an intermediate container. Once the intermediate container is in a lower position, a box is pushed over the intermediate container and the intermediate container is swung through a 90.degree. arc onto a conveyor belt. The intermediate container is then removed from the box and by this process the tubular bags which were previously in the intermediate container are transferred into the box.

  • Patent number: 4393759
    Abstract: A cheese making apparatus comprises a rectangular vat, a pressing plate, a filtering sheet supported on the bottom wall of the vat for displacement in a longitudinal direction, and a transverse partition affixed to an end of the filter sheet adjacent a fixed end wall of the vat for simultaneous displacement with the filtering sheet in this direction. The partition defines with the side walls, the bottom wall and a mobile end wall opposite the fixed end wall an operating volume of the vat determining the amount of curds to be held in the vat for producing cheese from a pressed mass of the curds wherefrom the whey has been drained. Displacement of the partition changes the operating volume and the transverse partition is elastically compressible in a vertical direction whereby lowering of the pressing plate into the vat compresses the partition and permits the plate to apply pressure to the curds held in the vat.

  • Patent number: 4289793
    Abstract: Large blocks of cheese are formed in a container having a removable bottom, side walls, and an essentially open top. A plurality of upstanding perforated tapered posts extend from the removable bottom to essentially the desired final height of the cheese block. The posts are longitudinally and laterally spaced from one another so that the curd surrounds each post when the container is filled with curd. Pressure is then applied downward to the curd in the container which compacts the curd and causes draining of whey through the upstanding perforated posts. After the curd has been compacted to the desired height, and the whey has been drained through the upstanding perforated posts, the container is inverted and the tapered posts are withdrawn. Pressure is again applied to cause the curd surrounding each perforated post to knit together and aid in removal of any additional whey, thereby providing a cheese block of uniform texture.

  • Patent number: 4241562
    Abstract: A method and apparatus for the automatic filling of plastic bags with, for example, elastic, soft and deformable contents. In order to provide for the automatic handling of empty bags without intermediate, especially manual, steps, the invention provides that the empty bags are attached by extending flaps to a plastic carrier web across a tear line. The apparatus of the invention places a quantity of goods into the bag by means of an axially moving filling piston which passes between spreadable jaws that hold the bag open. The continued motion of the filling piston eventually exerts a force sufficient to cause fracture along the tear line and separation of the filled bag from the flap which stays attached to the carrier web. The piston then moves the filled bag into position for sealing. A number of embodiments is presented.
