Abstract: A supply device which, in a retainer type continuous-filling packaging system, converts the movement of empty bags supplied intermittently in a plurality of rows into a continuous motion in a single row and supplies these empty bags continuously to retainers that are conveyed at a constant speed. The supply device includes an empty-bag holding member conveying device and an intermittent bag supply device. In the empty-bag holding member conveying device, a plurality of empty-bag holding members (that contain therein empty bags) disposed at equal intervals are moved in one direction along a ring-form track that has a pair of parallel sections, and during this movement, the empty-bag holding members are moved intermittently by a specified distance (a distance equal to an integral multiple of an attachment spacing of the empty-bag holding members) on a bag entry side of the parallel sections and are moved continuously at a constant speed on a bag exit side of the parallel section.

Abstract: An apparatus for extracting product-filled bags from retainers that are conveyed along a rectilinear path. The extracting apparatus includes a base member disposed along a base guide path parallel to the rectilinear path of the retainers so that the base member is free to make a reciprocating motion, a frame member supported on a supporting shaft on the base member so as to swing upward and downward, a sliding shaft member supported on the frame member so as to advance and retract, and a holding means disposed on the front end portion of the sliding shaft member. A cylindrical cam roller is attached to a cam roller attachment link which is pin-connected to the lower portion of the frame member, and the cam roller rolls through the cam groove of a raising-and-lowering cam, thus allowing the frame member to swing upward and downward about the supporting shaft.

Abstract: In a method and apparatus for inserting empty bags into retainers, guide members are caused to approach both side edges of each supplied bag so that the vertically oriented guide grooves of the guide members contacted the side edges of the bag, thus positioning the bag in a position that is vertically aligned with a retainer. The bag mouth is opened by suction disks, and a plug is brought into the opened bag mouth. Then, the plug is lowered toward the retainer, so that both side edges of the bag is inserted into the insertion grooves of the retainer. After this insertion, a compressed gas is jetted out of a discharge opening at the tip end of the plug into the bag, so that the bag is spread open to the bottom thereof.

Abstract: A discharge device which, in a retainer type continuous-filling packaging system, extracts full bags (bags filled with contents) from retainers that are continuously fed at a constant speed and discharges these full bags after converting the movement of the bags into an intermittent movement of a plurality of rows. The discharge device includes a full-bag holding member conveying device and a product-conveying conveyor.

Abstract: A conveying device in which articles supplied intermittently in a plurality of rows are discharged continuously in a single row, comprising a rotational conveying mechanism and a reciprocating driving mechanism. The rotational conveying mechanism rotationally conveys numerous empty-bag holding members disposed at equal intervals in one direction along a ring-form track (or race-track path) which has a pair of parallel sections, and the reciprocating driving mechanism causes the rotational conveying mechanism as a whole to perform a reciprocating movement through a specified distance along the parallel sections of the ring-form track. On a supply side of the parallel sections, the empty-bag holding members are moved intermittently by a distance that is equal to an integral multiple of an attachment spacing of the empty-bag holding members; while on a discharge side of the parallel sections, the empty-bag holding members are moved continuously at a constant speed.

Abstract: A rotary type continuous filling apparatus that continuously fills bags accommodated in retainers with a filling liquid via filing nozzles. A cylinder of each of the pump devices that correspond to the respective filling nozzles is installed horizontally with the discharge opening facing outward. The discharge opening communicates with a feed-out opening of a nozzle main body, and a tank containing the filling liquid communicates with a supply opening of the nozzle main body via a flow passage. A cam roller is connected to the piston via swing levers, vertical supporting shafts and cam levers, and these cam rollers move along an annular cam groove of a piston operating cam. Furthermore, each filling nozzle has a flow passage switching valve that switches between a communication and non-communication of the supply opening and the feed-out opening, and it also has an opening-and-closing valve that opens and closes the discharge port.

Abstract: A rotary type transfer apparatus used in a continuous manufacturing apparatus for spout-equipped bags. The transfer apparatus includes a transfer rotor and a driving device and installed next to an extraction apparatus. The transfer rotor has spout holding members on its circumference, and the driving device causes the transfer rotor to rotate intermittently in a cycle of stopping, acceleration, constant-speed rotation, deceleration and stopping and causes the speed of the spout holding members of the transfer apparatus to coincide with the speed of the spout holding members of the extraction apparatus during the period of constant rotation and causes the spout holding members to run side by side. During the constant-speed rotation, spouts are transferred from the spout holding members of the continuously rotating extraction apparatus to the spout holding members of the rotary type transfer apparatus via a guide member.

Abstract: A continuous container-supplying apparatus in which a plurality of container holding assemblies, each comprising right-side and left-side holding members are provided on conveyor belts that run as an integral unit along an annular track that has a pair of parallel sections. Containers are intermittently supplied to the container holding assemblies on one side of the parallel sections, and then converted into a continuous movement in a single row on another side of the parallel sections so that containers are continuously supplied to a filling and packaging system. The right-side holding members are provided on the upper conveyor belt, and the left-side holding members are provided on the conveyor belt. When containers of different width are to be supplied, the relative positional relationship of the upper and lower conveyor belts in the conveying direction is adjusted so as to change the spacing between the right-side and left-side holding members.

Abstract: An apparatus for inserting spouts into bags comprising a plurality of spout holding member disposed at equal intervals on the circumference of a continuously-rotating rotating table; and a pair of holding members which position and hold both side edges of bags, bag bottom receiving stands that support the lower ends of the bags, and suction plates which open the mouths of the bags with suction. The holding members hold side edges of supplied bags, the bag bottom receiving stand is raised to move the mouths of the bags to the suction plates, and the mouths of the bags are opened by suction by the suction plates. Then, the holding members, bag bottom receiving stand and suction plates are raised, and bags are fitted over the spouts and raised to the upper end of the sealing portion of the spouts. Afterward, the bags and spouts are temporarily sealed.

Abstract: A retainer with a bottomed retaining hole and a pair of insertion grooves so that a self-standing packaging bag in a closed state is set in the retaining hole and insertion grooves and then the bag is opened and kept opened during packaging operations. The retaining hole that is vertically formed accommodates the body portion of the self-standing packaging bag, and both side edges of the bag are inserted in the insertion grooves which are vertically installed in symmetrical positions on both sides of the retaining hole. The depth of the bottomed retaining hole and insertion grooves is set to be smaller than the length of the self-standing packaging bag, the spacing between the end portions of the insertion grooves is set to be equal to or greater than the width of an unopened self-standing packaging bag, and the angle between the inside surfaces of the retaining hole and insertion grooves is set at or about 90 degrees.
