Abstract:
Encapsulation apparatus for forming capsules by dropping a coagulatable mixture into a coagulation tank, including a dropping tank with a perforated bottom and a coagulation tank beneath the dropping tank. The dropping tank has a shallow mid-section and deeper portions at the inlet and discharge ends. Pumps provide circulation between the discharge and inlet ends of the coagulation tank.
Abstract:
An apparatus for taking a material to be treated into and out of a treating high pressure tank such as a heating sterilization tank comprises a conveyor passage interconnecting the high pressure tank and a water tank and constituted by two or more partially cylindrical casings connected in a side-by-side relation and each rotatably accomodating a rotary closure member having 2 to 6 blades adapted to make a sliding contact with the inner peripheral surface of the casing. Due to a specific phase difference between the blades of adjacent rotary closure members, the conveyor passage is always closed by some of the blades. A pair of endless conveyor chains, carrying a plurality of treating vessels accomodating the material, are adapted to run along both side surfaces of the conveyor passage through the high pressure tank and the water tank in a timed relation to the rotation of the rotary closure members. Means are provided for returning the leaked liquid back to the high pressure tank from the water tank.
Abstract:
A device for screw-tightening caps on containers such as bottles has a cap chuck head for grasping and holding each cap with holding pawls, a driving shaft, and a friction clutch mechanism constructed separately from the chuck head but mechanically coupling the driving shaft and the chuck head to transmit rotational power to the chuck head at torques below a predetermined maximum torque, at which the cap is screw tightened, friction plates of the clutch mechanism slipping at any higher torque to prevent excessive tightening. The separate construction of the clutch mechanism and the chuck head prevents subsequent engagement of the clutch plates due to reaction forces arising during the screw-tightening operation, thereby preventing excessive tightening.
Abstract:
A sterilizer which has two transfer chains moving through sterilizing and cooling tanks; open-backed transfer containers with holes in their walls and locking members at both ends, which are supported between the chains; and inner vessels containing the materials being treated, which have holes in the walls thereof and locking means, which are engageable with the locking members, at both ends thereof, and which are adapted to be removably inserted into the containers. Projections extend inward from the circumferential edges of the holes in the walls of the containers and/or inner vessels, serving to support the materials and define liquid passages between the materials and the inner surfaces of the containers and/or inner vessels. Two front intermittent driving wheels and two rear intermittent driving wheels are provided in an inner vessel insertion and discharge section, the chains are wrapped around these wheels so that the parts of the chains which are in front of the front wheels, behind the rear wheels, and between the front and rear wheels hang loosely, an insertion means provided at one side of the front wheels fits the inner vessel from a material feed means into a container supported on the front wheels, a discharge means provided at one side of the rear wheels forces the inner vessel out of the container supported on the rear wheels onto a treated material removal means, and inner vessel guide members for guiding the inner vessels into the transfer containers are provided between the feed means and the front wheels, and between the removal means and the rear wheels, and which are adapted to move pivotally to horizontal positions only when a inner vessel is being inserted into or discharged from a container.
Abstract:
The top seal parts of bottle-like containers made by blow-molding a flexible synthetic resin are cut off by nonrotatably supporting each container, pressing from one side a cutting edge of a cutter against a specific cutting line on the top part of the container, and rotating the cutter around the top part thereby to cut off the top seal part. This process can be carried out by an apparatus comprising a plurality of combinations of mechanisms, each combination comprising a fixing device for nonrotatably and fixedly supporting a container, a cutting head which can be fitted onto the top seal part of this container and can be driven in ascending, descending, and rotating movement, and cutting head drive.
Abstract:
An apparatus for intermittently transferring a suitable number of cylindrical plastic containers using a conveyor, which comprises a vessel stopping and transferring wheel which is rotatably disposed on one side of the conveyor, on which the cylindrical vessels are placed, and which has in the peripheral portion thereof arc-shaped recesses which are engageable with the side surface of the cylindrical vessels; a cam having flat surfaces and operatively connected to the vessel stopping and transferring wheel via toothed wheels; a buffer having at the free end portion thereof a roller slidingly engageable with the flat surfaces of the cam; and a control for disengaging the roller from the flat surfaces of the cam. Owing to the buffer operatively connected to the vessel stopping and transferring wheel via the cam, shocks given to the vessel stopping and transferring wheel when the vessels are thereby stopped are damped remarkably to prevent the vessel stopping and transferring wheel as well as other parts from being worn, damaged or loosened.
