摘要:
An empty bag supplying apparatus used in a continuous conveying type bag-filling packaging machine in which the empty bag supplying apparatus receives empty bags and transfers these empty bags to gripper pairs of the bag-filling packaging machine that are moved continuously at a constant speed. The empty bag supplying apparatus includes downward-facing bag holding members and a reciprocating movement mechanism. The bag holding members hold the upper portions of bags. The reciprocating movement mechanism causes the bag holding members to reciprocate along an arc-shaped path and keeps the empty bags held by the holding members to be parallel to the direction of movement of the gripper pairs during the reciprocating motion. In a bag transfer region established in the arc-shaped path path, the speed of the bag holding members holding the empty bags is equal to the moving speed of the gripper pairs.

In a device that opens the mouth of each one of the bags that are suspended with the mouths facing upward and conveyed in a vertical state at a uniform speed and uniform spacing in a straight line, a pair of suction disks revolve continuously in mutually opposite directions on circular tracks on the horizontal plane so that the suction-chucking surfaces of the suction disks are always caused to face each other. The suction disks revolve at a constant speed while maintaining substantially symmetrical positions relative to each other and revolve at the same speed as the speed the bags are conveyed.

An opening apparatus that opens continuously conveyed bags with a gas supplied by nozzles. A plurality of nozzles having conical head sections and discharge openings at the tip ends are attached to a rotation transmitting member with equal spaces in between, and this rotation transmitting member is caused to revolve at a constant speed while maintaining a horizontal attitude by means of a parallel link mechanism. The nozzles revolve at a constant speed on a circular track in a vertical plane along the conveying direction of bags with the discharge openings consistently facing the bags. When the nozzles are at the lower point on the circular track, the head sections enter into the bags that are being conveyed at a constant speed, and a gas is caused to jet into the bags from the discharged openings, thus spread-opening the bags.

A packaging processing (liquid filling) apparatus, including a rising-and-lowering assembly attached to a pivot member and moved vertically and filling nozzles attached to the rising-and-lowering assembly. An endless chain having grippers at equal intervals is rotated continuously by a sprocket. A circular first raising-and-lowering cam that rotates with the sprocket is attached to the sprocket, and a circular-arc-shaped second raising-and-lowering cam is provided near the first raising-and-lowering cam; and a cam roller attached to the rising-and-lowering assembly is caused to roll on these cams. When the pivot member makes a forward motion to follow the bags held by grippers, the cam roller rolls over the second raising-and-lowering cam, and the rising-and-lowering assembly is lowered and then raised; when the pivot member makes a return motion, the cam roller rolls over the first raising-and-lowering cam, and the rising-and-lowering assembly is maintained in a raised position.
摘要:
A guide device for loading a solid matter into a bag including: an upper hopper which performs a reciprocating swinging motion along the conveying direction of the bag and about a supporting shaft located in the center of the upper portion of the upper hoppers, and a lower hopper which is positioned beneath the upper hopper and performs a reciprocating horizontal motion along the conveying direction of the bags and also moved toward and away from the upper hopper. The upper hopper's swing motion and the lower hopper's horizontal motion along the conveying direction of the bag are made in synchronization with the movement of the bag, and the lower hopper is lowered so that its lower opening is inserted into the mouth of the bag.
摘要:
A bag conveying apparatus including a sprocket continuously rotated on a horizontal plane, a fixed guide member having a guide section of a semicircular shape, and an endless chain mounted between the sprocket and the guide section of the guide member. The endless chain is comprised of a plurality of links connected by connecting shafts. Guide rollers rotatable about their own vertical axes are disposed on and under each connecting shaft, and an inside guide roller rotatable about its own horizontal axis is disposed on the inner side of each link. The guide section of the guide member has roller guide sections that contact the guide rollers of the endless chain, and the guide section also has a guide groove in which the inside guide rollers of the endless chain are fitted. Grippers that grip both edges of a bag are installed on each link.

In an intermittently rotating table type bag filling apparatus, a plurality of pairs of grippers being provided at equal intervals around an intermittently rotating table, the grippers including pairs of left and right swing levers mounted on the intermittently rotating table, gripper arms affixed to swing levers, chuck sections installed in the tip end portions of the gripper arms, and chuck open/close mechanisms that open and close chuck sections. Gripper arms are cylindrical, and air cylinders and link mechanisms that constitute chuck open/close mechanism are installed inside the tube bodies of the gripper arms.
摘要:
A bag filling and packaging apparatus including hollow guide members that are disposed below ascending/descending hoppers and guide product dropping from hoppers into the interior of bags, the guide members being raised/lowered and moved together with the hoppers in a filling region. The guide members comprise a pair of opening and closing guide frames that are disposed to face each other; and when clogging is detected in a guide member, its guide frames are repeatedly opened and closed while moving through a non-filling region, thus promoting the dropping of product. Directly below the guide members is provided a receiving member that receives the product.

A heat-sealing apparatus comprising a pair of opposed hot plates and a pair of hot plate-mounting blocks to which said hot plates are mounted, respectively. The hot plates respectively have pressing surfaces adapted to be pressed against each other with superimposed film sheets held therebetween during sealing; and mounting surfaces formed at opposite sides to said pressing surfaces. The hot plate-mounting blocks respectively have support surfaces. The hot plates are mounted to said hot plate-mounting blocks in such a manner that the mounting surfaces are pressed against the support surfaces, and that the hot plates can thermally expand and contract in a sealing direction without being restrained by said hot plate-mounting blocks. In another aspect of the invention, the mounting surfaces are formed on respective surfaces extending substantially perpendicular to the pressing surfaces and the hot plates are mounted on respective support surfaces formed on the hot plate-mounting blocks.
摘要:
A rotary and flow meter type liquid filling apparatus including a liquid reservoir tank that stores and supplies liquid to filling nozzles, and air supply paths for different amount of air supply and air discharge paths for different amount of air discharge being connected to the liquid reservoir tank. An air compressor is connected to the air supply paths, and the air discharge paths open into the atmosphere. A liquid pressure sensor disposed near the filling nozzles sense the increase or decrease of the liquid pressure inside a pipe that connects the liquid reservoir tank and liquid filling nozzles, and the electromagnetic valves provided on the air supply and air discharge paths are opened or closed, thus supplying air to and discharging air from the liquid reservoir tank so as to control the air pressure inside the liquid reservoir tank and the liquid pressure near the liquid filling nozzles.
