  • Patent number: 5205110
    Abstract: An indexing motion apparatus and method for vacuum packaging of articles such as hot dogs, sliced luncheon meat, cheese or pharmaceuticals. A lower web of packaging material is indexingly advanced by a lower web drive driven in an indexing manner by a servo motor. Forming tooling is provided for vacuum forming the lower web to form one or more product cavities, and the forming tooling is movable between raised and lowered positions by a lifting and lowering system driven by a servo motor. A plug assist mechanism is provided for assisting the web to conform to the forming cavities. The plug assist mechanism is also movable in response to operation of servo motors, which actuate a pair of linear actuators. After the formed product cavities are loaded with product, the cavities are evacuated and an upper web applied to vacuum package the product. A slitting mechanism severs the upper and lower webs into individual product packages.

  • Patent number: 5155981
    Abstract: A device comprises an arm pivoting on and supported by a shaft positioned between a station, where a sealed blister strip is cut into individual blister packs, and a blister pack infeed conveyor. The arm is made up of two pieces fitted with suction cups, and oscillates between two positions, so that in a first position the suction cups are at the cutting station, on a smooth surface of a blister pack just cut, while in a second position they are at the side of a pickup bucket, on the infeed conveyor. The suction cups are actuated in the first position, so that the blister pack can be picked up, and then the suction cups are disenabled in the second position, so that the blister pack can be fed into the bucket, with deep-drawn blisters turned upwards. Sidepieces provide for centering the blister pack in respect of the longitudinal axis of said infeed conveyor, while infeeding the blister pack into the bucket.

    Abstract: For baling shrubs or bushes, in particular rose bushes, the roots (12) of the plants (10) substantially freed from soil are embedded in a moisture-containing substrate (14) such as peat and provided with a sheath or envelope. For this purpose a hollow of wire grating (16) is formed which is then partially filled with substrate (14). Thereafter the roots (12) of the lying plant (10) are placed on the substrate (14). Further substrate (14) is then applied to the roots (12). Finally the wire grating (16) is deformed by bending two edges (24, 26) of the hollow together to form a tube and the edges (24, 26) of the wire grating (16) are fixedly connected together. A machine for carrying out this method comprises at least one trough (48) onto which the wire grating (16) can be placed. A ram (74) is shaped complementary to the trough (48) and adapted to be pressed into the latter to deform the wire grating (16 ) to a hollow.

The advances achieved by this control system are: High speeds are achieved by synchronizing the machine index cycle and tooling controls, permitting the prestart of tooling before the end of the index cycle; because the motor speed is monitored and profiled by the computer continuously, faster machine speeds can be achieved while maintaining the minimum machine jerk; total index time savings; diagnostics which dramatically reduce machine down time as a user friendly hard-copy print out is produced describing and pinpointing locations of malfunctions in the timers, tooling, and motor performance; access to all timer control settings through easy to use thumbwhell switches. In addition, a new arrangement of the tooling stations is used, allowing for the increase of per cycle capacity several times the capacity of the prior art.

Thereafter, the foil-parts lying on each side of the centerline are heated and are folded up about the said centerline, which thereby becomes a fold-line to form open containers which are then sealed, at a first sealing station around their peripheries, except for the perpheries of the upwardly projecting tubular parts. The edges of the foil are then spread apart in the vicinity of the said tubular parts, through which the containers are filled.

  • Patent number: 4835942
    Abstract: A vacuum packed, frozen, cooked or non-cooked shrimp pack, in which the shrimp-containing plastic pouch has a center thickness less than its outer, surrounding periphery, with more shrimp contained one above the other at the peripheral edges in comparison to a lesser number at the center in the pack. This produces a relatively even heating or cooking of the shrimp when the frozen pack is placed in a micro-wave for defrosting or cooking. Such a pack can be produced by providing an upwardly curved, rigid form underneath the bottom film layer of the pack in the "form, fill and seal" machine during commercial packing of the product in the sealing station and, if so desired, in the forming and fill stations. The rigid form can be provided by a curvi-linear section (FIG. 4) or a hemispherical section (FIGS.

  • Patent number: 4800705
    Abstract: A form, fill, seal and separate packaging machine wherein receptacle forming, filling and sealing is accomplished by a plurality of stations disposed along the path of travel of a web which continuously moves through the packaging machine. Both the base web material and the lid web material are supplied to the packaging machine from supply rolls of appropriate material. Not only are the work stations of the machine constructed and disposed so that the packaging operation is performed on a continuously moving web, but also both the base and lid web supplies include primary and secondary rolls so that the source of web material may be replenished without interrupting the continuous movement of the web material through the machine. Once the receptacles have been formed, filled and sealed, the packaging machine further includes an intermittent drive station for perforating and cutting the sealed receptacles from the main web body.

  • Patent number: 4793121
    Abstract: A pre-forming technique for web material utilized to make flexible pouches for fluent products comestibles and non-comestibles in form-and fill equipment of well known type characterized by the initial stretching displacement of each web from its normal plane and in a configuration corresponding to the ultimate spout configuration prior to forming of the pouch with the spout therein, thereby preventing undesired blockage of the spout by unintended adherence of the packaging film in the spout zone during sealing operations. The technique is especially desirable in pouches having a unique and complex reversely curved discharge passageway.

  • Patent number: 4730761
    Abstract: A method for cutting flexible formed shell product from a flexible plastic foam sheet. In the method, a foam shell formed in the sheet is drawn into and positioned in a die unit lower cavity and the die assembly is clamped together. A cutting die unit having dual curved serrated knife elements then descends and severs the formed shell from the sheet at all locations except for two short segments located at opposite ends of the formed shell. Then as a separate step, the partly severed formed shell is punched out from the flexible foam sheet, so as to provide multiple formed products. The products are usually formed as multiple units oriented in an end-to-end relationship in the foam sheet and which are simultaneously severed from the sheet. Cutting die apparatus adapted for cutting the formed products from the foam sheet is also disclosed.

  • Patent number: 4726173
    Abstract: In a machine for making sealed containers such as blister packages, the continuous feeding of the films (1, 7) for the formation and sealing of the containers is effected alternately by at least one unit of side clamping grippers (13) and by a unit comprising the stations operating cyclically on the films, namely, a heating station (3), a container-forming station (4), a sealing station (6) and a cutting station (8). The grippers and stations are movable on rectilinear guides (11, 12) disposed parallel to the path of travel of the films, and the operative units are reciprocated over the guides by a mechanism comprising a single cylindrical cam (24) having a closed helical outline or profile that is followed by two cam-followers (21-21') angularly spaced 180.degree. from each other and slidable on stationary guides p parallel to the axis of the cam.
