Patent number: 7900421Abstract: Packaging tools, which, in various embodiments, are adapted to assist a user in applying material from a roll of packaging material (e.g., packing tape, stretch wrap or shrink wrap) to an item or group of items. The packaging tool is typically adapted to move between: (1) a first orientation in which the packaging tool does not substantially restrict the rotation of the roll of packaging material adjacent the packaging tool; and (2) a second orientation in which the packaging tool does substantially restrict (e.g., prevent) the rotation of the roll of stretch wrap tool adjacent the packaging tool. A user typically maintains the packaging tool in the first orientation as the user wraps the packaging material about an item. The user may then move the packaging tool into the second orientation, which allows the user to pull the packaging material tight and separate the applied length of packaging material from the roll.Type: GrantFiled: August 8, 2008Date of Patent: March 8, 2011Assignee: United Parcel Service of America, Inc.Inventor: Steven L.

In either such form, the system enables weighing, computing, label printing and hand labeling of wrapped products without loss of productivity. The arrangement eliminates the need for an additional computing scale and label printer, such as would be necessary to obtain the same productivity with separate wrap stations using such equipment. An audible signal is provided to indicate that the scale has completed a weighing, enabling ease of the operators' pacing of their alternating manual functions, without each having to watch the other's actions.Type: GrantFiled: December 3, 1990Date of Patent: November 17, 1992Inventor: Fritz F.

Patent number: 4599847Abstract: In wrapping machinery for wrapping articles in heat sealable plastic film, a web of film is drawn from a supply roll and is severed by pulling the film under tension downwardly onto the narrow edge of a thermal cut-off device, which may be a heated rod or blade, to melt the film material along a thin transverse line and to permit severance thereof by pulling. Following severance of the film, the film-wrapped package is sealed by placing the package on a pedestal hot plate. The temperature of the hot plate is higher than that of the thermal cut-off device used to sever the film. The hot plate is supplied by electrical energy from a single source through a temperature sensor and control. The thermal cut-off device obtains its heat by conduction from the hot plate.Type: GrantFiled: January 31, 1985Date of Patent: July 15, 1986Inventor: Arthur L. Reenstra

Patent number: 4598531Abstract: A free end portion of sheet wrapping material is grasped and pulled from a dispenser transversely past and spaced from a cutting element mounted on a housing. The cutting element is displaced in response to the movement of the withdrawn material by generating a displacement force, latching the cutting element against displacement in a normally guarded position in which the cutting element is inoperative for cutting, and thereupon unleashing the displacement force in response to a further movement of the material to drivingly displace the cutting element from the guarded position to a cutting position in which the cutting element is in a position to sequentially pierce and cut the sheet material that is subsequently moved toward the same. Methods of dispensing the sheet material and of wrapping items also are disclosed.Type: GrantFiled: October 28, 1985Date of Patent: July 8, 1986Assignee: Clik-Cut, Inc.Inventors: Stanley L. Ruff, Albert Stubbmann

Patent number: 4570423Abstract: A tree ball tying apparatus is disclosed comprising a tripartile inverted, truncated conically shaped holder whose included angle is less than 60.degree. and is made of sheet metal attached to a stand by its rearmost part. The two forward parts are hinged, latchable doors which swing open or may be closed and latched in the conical shape. Cordage is woven around hooks and pins in the peripheries of the cone's base and truncation to form a sling over which is placed a degradable material such as burlap. A tree, whose ball is conically cut with typically a 60.degree. included angle, is removed from the ground and installed ball first onto the burlap and sling and set down sling and burlap first into the holder whose included angle is less than that of the ball thereby holding it above the truncation. Thereafter the burlap is folded around the tree trunk and tied with the loose ends of the sling and the tree removed from the holder with its ball wrapped and tied.Type: GrantFiled: December 11, 1984Date of Patent: February 18, 1986Inventor: Russell DeLong

Patent number: 4568818Abstract: A hand wrapper for plastic film that thermally cuts a length of plastic wrapping film withdrawn from a supply roll includes an improved heat cutter that uses film resistors instead of a metal blade or a single heater wire for the cutting because the film resistors are not likely to break and they have low heat capacity which permits instantaneous cutting of the plastic film without requiring preheating which causes large power losses.Type: GrantFiled: February 6, 1984Date of Patent: February 4, 1986Inventor: Shigeru Ikemoto

Patent number: 4565045Abstract: A wrapping device comprises a free wheeling film roll mounted on a frame, a film withdrawal slot to guide the film exterior of the frame, a detector to detect the withdrawn film length, a comparator which produces a locker signal each time when the film withdrawn accords with a predetermined length of the film by means of detector signal from the detector, a locker structure for locking the roll in the film withdrawal direction by means of the locker signal, and a press roller to seal the film about a wrapped goods-laden tray. The film on the roll is prevented from being unnecessarily withdrawn and thus allows and economical use of the film.Type: GrantFiled: March 7, 1983Date of Patent: January 21, 1986Inventor: Shigeru Ikemoto

Patent number: 4557102Abstract: A wrapping apparatus comprises a film roll placed on a pair of support rollers, a film withdrawal port to introduce the film on the roll exterior, a severing tool to cut the film introduced through the port, a film length determiner to detect the leading end of the film partly thrown around product so as to calculate the successive length of the film required, a film length detector which detects the length of the film withdrawn as calculated by the determiner, and a brake assembly which is applied to the support roller to stop withdrawal of the film on the basis of signals generated from the detector. The amount of film on the roll that is withdrawn corresponds to the dimensions of the product to be wrapped.Type: GrantFiled: September 29, 1983Date of Patent: December 10, 1985Inventor: Shigeru Ikemoto

Patent number: 4551962Abstract: A novel weighing and packing apparatus is provided by which an article is weighed, and weighed article is manually packed with film. The apparatus may be provided at its working table with a packing device for manual packing and a weighing mechanism in an integral manner, or further with a label printer. According to the apparatus provided, an improvement in working efficiency in weighing and packing work is realized. Further, a working space can be minimized.Type: GrantFiled: September 21, 1982Date of Patent: November 12, 1985Assignee: Teraoka Seiko Co., Ltd.Inventor: Kazuto Kawahara

Patent number: 4524559Abstract: A hand wrapping apparatus for manually wrapping products such as a food-laden tray by a web-like package film emanated from a film roll. The apparatus comprises a film roll, a film withdrawal slot to introduce the film into exterior therethrough in response to the unrolling action of the film roll, a film severing tool arranged in the neighborhood of the slot, a rocker bar having an upper end positioned to meet the slot across the severing tool and being usually urged by a spring toward the severing tool, and a heat sealer mounted on the end of rocker bar in order to weld the film around the product, and, at the same time, have the rocker bar pivot against the force of the spring to sweep the film past the severing tool to cut it when the product is placed thereupon.Type: GrantFiled: August 4, 1983Date of Patent: June 25, 1985Inventor: Shigeru Ikemoto
