  • Patent number: 5535573
    Abstract: An apparatus (blank unit) for feeding blanks to an article to be wrapped is disclosed. In the feeding of blanks (13) or of a web of material (14) made from critical packaging materials (thin foils), suction conveyors (32 . . . 37) are used which transport, guide and retain the web of material (14). An optimum guidance of the web of material (14) is ensured when lateral elongated suction conveyors (32, 33) reach below a pack track (15). Additionally, shorter suction conveyors (34 . . . 37) are disposed above the pack track (15) in the region of the web of material (14). To adjust the blank unit to different widths of the web of material (14), the lateral elongated suction conveyors (32, 33) can be displaced transversely relative to one another. Moreover, individual shorter suction conveyors (34 . . . 37) can be removed.

  • Patent number: 5483783
    Abstract: A method and apparatus for placing sleeves on bottles and other objects is disclosed. In particular, a high speed method and apparatus having a plurality of sleeving stations for placing sleeves on bottles is disclosed. Each sleeving station includes a circularly arranged set of relatively movable parallel pins which are operable to contract or expand. A label transporter deposits a sleeve on the pins when they are contracted. The pins expand to stretch the sleeve. A bottle and the pins are then moved relative to one another to place the bottle inside the stretched sleeve. A gas flow is provided between the bottle and the sleeve to reduce friction. The sleeved bottle is then stripped from the pins. The method occurs without starts and stops by the bottle or the sleeve and is thus capable of very high production rates.

  • Patent number: 5437141
    Abstract: The method is performed on a tape banding machine with a winding tape made of a paper tape coated with plastic or lacquer which forms at least one tensionable loop. The loop is severed after tightening and binding the winding tape. When forming the loop, the tape banding machine directs the plastic or lacquer layer of a winding tape which is coated on one side onto its uncoated surface made of porous paper. Where the winding tape is coated on both sides, the plastic layers are directed onto each other. The free end is bound to the aforementioned winding tape by ultrasonic cold welding. The flat working surface of the sonotrode of a tape banding machine is divided into sections by at least one recess; it consists of preferably small grid surfaces. The recesses are preferably grooves which run in a lengthwise direction and at an angle of 30.degree.-60.degree. to this lengthwise direction.

  • Patent number: 5433059
    Abstract: An apparatus and method are provided for wrapping roll material around a round bale within a bale forming chamber of a round baler including a drive belt tensioner idler, a wrapping material brake and a wrapping material cut-off knife all disposed on a carriage that is articulated between a wrapping material feeding position and a cut-off/stop position. When baling is completed, a signal is provided for movement to the feeding position at which time the wrapping material is held taught to maintain bale compression. After sensor data are fed back to a controller to signal feeding has proceeded for the desired length of time and/or to deploy the desired length of wrapping material, the device articulates to the cut-off position to sever the wrapping material to allow completion of the bale wrapping procedure. A crop recycling mechanism can also be provided to re-feed stray crop material into the baling chamber.

  • Patent number: 5433061
    Abstract: Apparatus (1) for removing excess air from sealed packages so as to prevent ballooning. The apparatus (1) comprises a first conveyor belt (3) along which the packages move through the apparatus (1). The conveyor (3) Is driven by two rollers (4 and 5) and is also arranged to vibrate, by means of vibrator (2), in order to settle the contents, e.g. rice, in the packages throughout the operation. When a package is in a predetermined position, as determined by a sensor, such as a photoelectric cell (7), the package is punctured by a suitable device such as a spike (8). As the package continues down the conveyor (3), excess air is removed from the package by means of a spring loaded conveyor (19) which is biased against the package. As spring loaded conveyor (19) is pressed against the package, air in the package Is forced out through the hole made by spike (8).

  • Patent number: 5430995
    Abstract: The end of a length of stretch film enveloping a pallet is restrained, prior to being heat-sealed, by a gripping mechanism that can be traversed toward and away from the pallet, and is capable of contracting longitudinally in a direction parallel to the plane occupied by the tail end of the film, transversely to the wrapping direction, from a position of engagement in which the gripping surfaces are spaced apart and uniformly in contact with the film over its maximum width, to a position of restraint in which the selfsame surfaces are drawn together, pinching the film to produce a uniform succession of folds and thus narrowing the material to a width that can be accommodated fully by the heat-seal plate.

  • Patent number: 5430994
    Abstract: An apparatus for transferring bag packs (10) containing sensitive loose material to a collective packer for the introduction of the packs into a carton or the like. To compensate for the difference in performance rates of a production machine (bag packer) for the packs (10) and the collective packer, there is provided a conveying device (17) with at least two conveyor belts (18, 19) which act as compensating conveyors. The packs (10) are fed to a special collecting station (16) by the conveying device (17). This collecting station comprises an intermediate band (35) and a group band (43). In the region of the intermediate band (35), the packs (10) are spaced out at a distance so they can be detected. In the region of the group band (43), a pack group (11) is formed from packs (10) lying tightly next to one another.

  • Patent number: 5426910
    Abstract: A compost bagging machine is described including a wheeled frame having a tunnel mounted thereon which is adapted to receive the opened mouth of a bag. The inside surface of the tunnel is provided with a plurality of spaced-apart flutes which create air channels in the material within the bag. An elongated perforated pipe is also positioned within the material in the bag and the bagging machine moves relative to the bag during the bagging operation. The presence of air in the channels created by the flutes and the air present in the perforated pipe ensures that sufficient air will be present in the mass to achieve complete decomposition of the material.

  • Patent number: 5425215
    Abstract: The present invention comprises a device and method for feeding a cut loose-leaf material such as, for example tobacco, from a weight scale; dropping the tobacco into a hopper; compressing the tobacco into the desired size, shape, and density; and packaging the loose-leaf tobacco product. Packaging is accomplished by wrapping an inner foil and overwrap label around an arbor on a rotating arbor wheel. The package is constructed in various stages as the arbor wheel rotates to various positions. The inner foil is fed and wrapped around the arbor without extending the foil below the body of the package so that the foil does not form a bottom end. The foil extends above the body of the package and is folded to form a top end. An outer label having a sufficient length to extend past the top and bottom of the arbor is overwrapped about the foil innerwrap. The overwrap label extending past the bottom of the arbor is folded and glued over the foil innerwrap to form a top end to the package.

  • Patent number: 5419102
    Abstract: A crop bagging machine is provided with a movable chassis having adjustable brakes and a grain container having a rear tunnel defining a rear opening. A pliable plastic bag is fit to the tunnel with the bag bottom closing the opening. A bin on the chassis receives grain, e.g., from a truck and an auger transports the grain from the bin to an elevated position in the container that is above the height of the filled bag. The adjustable brakes are set to establish the level of grain pile in the container to cover the opening and thereby fill the bag. The brakes are independently controlled to provide limited steering. An additional embodiment of the invention shows downsizing for reduction in cost and in dimension for compatibility with conventional shipping containers while further providing adjustability in tunnel size to accommodate variation in bag diameter. A further additional embodiment provides for a modified conveyor system for the grain that utilizes air flow.
