Patent number: 7134256Abstract: The present invention provides a packaging system that includes a beak-shaped hopper, a pair of opening and closing bars, and a sensor for sensing a limitless opening and closing movement of the opening and closing bars. The beak-shaped hopper and the pair of opening and closing bars are operable to move in unison back and forth along a main travel path. The main travel path leads to a rotary vacuum packaging device having a pressure resistant chamber. The beak-shaped hopper is dimensioned to convey packaging bags into the pressure resistant chamber. The opening and closing bars are dimensioned to detect a bag on the hopper by opening towards both sides immediately after a bag has been conveyed into the pressure resistant chamber. A pushing bar is dimensioned to convey an item to be packaged into the bag when the bag is detected on the hopper by the opening and closing bars. The opening and closing bars contact a sensor for detecting movement of the opening and closing bars when a bag is not on the hopper.Type: GrantFiled: July 29, 2004Date of Patent: November 14, 2006Assignee: Furukawa Mfg.

Patent number: 6834472Abstract: An article to be packaged and a packaging bag for covering the article are supplied to heat sealing mechanisms which arrive at uniform time intervals, in synchronism with cycle timing of the respective heat sealing mechanisms. A vertically openable beak-shaped hopper and a sliding plate perform reciprocal movement at a uniform time interval along guides on both sides, and arrive at circulating sealing platforms. The hopper is inserted into an opening of the packaging bag hanging down from above, and conveys the packaging bag to the sealing platform whilst extending the same. In response to a relevant signal, a forward-and-reverse motor coupled to a ball screw causes the article to advance following the hopper by an insertion rod moving along the guides.Type: GrantFiled: August 12, 2003Date of Patent: December 28, 2004Assignee: Furukawa Mfg.

Patent number: 6458228Abstract: A hammer (14) coupled to an ultrasonic vibrator (15) is actuated to apply vibrations to a wrapping material (10) with irregularities in composition and thickness so that the wrapping material (10) can be fusion-bonded with uniform strength. The surface temperature of the wrapping material (10) measured by an infrared sensor (30) is sent to a control unit (22), and a controller (23) sends a control signal (24) to a variable-voltage source (25). The variable-voltage source (25) controls the amplitude of vibrations of the hammer (14) by temperature feedback to make uniform the generation of heat in the wrapping material (10).Type: GrantFiled: May 8, 2001Date of Patent: October 1, 2002Assignee: Furukawa Mfg.

Patent number: 6374580Abstract: A method and apparatus for controlling operation of a bag-forming and -filling packing apparatus for supplying unsealed packaged articles (45) to a rotary vacuum packaging machine at regular intervals, in which the rotary vacuum packing machine is subjected to significant variations in loads. A main controller (115) for receiving pulse signals calculates modulation of the pitch of pulses from a main motor (86) of the rotary vacuum packaging machine, and control elements (94, 95, 96, 97) each attached to a corresponding one of all servo motors (20, 30, 40, 76) of the bag-forming and -filling packaging machine individually and simultaneously control the rotation value of each servo motor. This configuration can avoid step-wise control of each servo motor and reduce impacts on a rotary section and a failure rate while maintaining a slow control operation.Type: GrantFiled: December 29, 1999Date of Patent: April 23, 2002Assignee: Furukawa Mfg.

Patent number: 5752369Abstract: An apparatus for controlling the operation of a packaging machine of the type which carries out the operations of causing a tube film placed around articles under transport to be cut and sealed between adjacent articles for being successively formed into bags, then causing individual bags, each with an article contained therein, to be conveyed forward by a delivery conveyor, causing the bags to be sequentially transferred from the delivery conveyor onto moving surface plates, causing each surface plate to be covered with a cover member, and then causing the interior of the cover member to be placed under a vacuum atmosphere while the open end of the bag is hermetically sealed. A bag sensor sequentially detects the passage of open ends of bags on the delivery conveyor, and a surface plate detecting sensor sequentially detects the passage of individual surface plates.Type: GrantFiled: October 21, 1996Date of Patent: May 19, 1998Assignee: Furukawa Mfg.

Patent number: 5386678Abstract: The track for a pressure chamber overlaps the track for a clamper in movement while clamping a bag filled with an article, at a position beneath the latter track and with a level difference. The bag supported by the clamper is held, at its upper edge positioned right below the clamper, between the upper side of a chamber body of the pressure chamber and the upper side of a cover and in a sealed condition. The air in the bag is expelled through a notched line formed in an upper portion of the bag as the pressure within the pressure chamber is reduced, and then the bag is sealed at a position below the notched line.Type: GrantFiled: July 12, 1993Date of Patent: February 7, 1995Assignee: Furukawa Mfg. Co., Ltd.Inventor: Eitaro Kujubu

Patent number: 5119615Abstract: A plurality of clamps arranged in equally spaced relation on an endless track are intermittently advanced at a pitch equal to the distance of each two adjacent clamps. A switch reactive only to the passage of a sufficiently heavy or filled bag which has been filled with an article is disposed downstream of a filling station, one of the stop positions for clamps. When the passage of a bag is not responded by switch, that is, when an empty or unfilled bag has passed near the switch, the particular clamp by which the empty bag is held is caused to pass through the final stop position and, in turn, through the first stop position before it can again reach the filling station, with the empty bag being held by the clamp all the while.Type: GrantFiled: July 11, 1991Date of Patent: June 9, 1992Assignee: Furukawa Mfg. Co., Ltd.Inventors: Eitaro Kujubu, Tadamichi Takeda, Tatsuo Higami, Hiroshi Yoshimoto

Patent number: 5009060Abstract: A vacuum packaging apparatus suitable for use in packing fluid foodstuffs or the like into bags. In a chamber are disposed a pair of support members having surfaces opposite relative to each other which are individually formed with suction holes. When a bag is fed between the pair of support members, vacuum is applied through the suction holes so that opposite surfaces of the bag are sucked into the opposite surfaces of the support members. Subsequently, the support members are moved away from each other, whereupon the mouth of the bag is opened. An object is fed into the mouth-opened bag for being vacuum packed therein. The resulting vacuum packaged product is supported in position between the pair of support members, being thereby flatly shaped.Type: GrantFiled: August 7, 1989Date of Patent: April 23, 1991Assignees: ECS Corporation, Furukawa Mfg., Co., Ltd.Inventor: Takao Furukawa

Patent number: 4903459Abstract: A method and apparatus for discharging vacuum packaged goods from a vacuum packaging apparatus. While a chamber held in contact with the upper surface of a table and defining an airtight space therein is in movement integrally with the table for one round of travel along an endless track, the chamber is lifted from the table for a given period of time for supply into the chamber of goods to be packaged as contained in a bag. When the chamber is again brought in contact with the table, a vacuum atmosphere is created in the chamber so that the mouth of the bag is sealed, vacuum packaged goods being thus obtained. A table portion within the chamber is formed with an open/close type drop opening which is sealed by a cover plate. The to-be-packaged goods contained in a bag, as well as vacuum packaged goods which are sealed at the mouth of the bag, are loaded on the cover plate.Type: GrantFiled: November 28, 1988Date of Patent: February 27, 1990Assignee: Furukawa Mfg. Co., Ltd.Inventor: Keizo Okinaka
