PROBLEM TO BE SOLVED: To reduce occurrence of mold defective articles by delivering with a label positioned, when delivering the label to a pseudo core. SOLUTION: Labels located on the lowest layer are taken out sequentially by sucking from a label stock section accumulated in a vertical direction with a large number of labels, in label insert molding for molding molded articles integrated with labels on the surfaces by injecting synthetic resin, after charging labels in dies.

Abstract:
PROBLEM TO BE SOLVED: To provide an automatic tool exchange operating in an excellent state, even when a coupling surface is directed in a direction other than a horizontal direction. SOLUTION: When a cam member 17 is shifted from an unlocking position to a locking position, locking balls 13 which slide on locking inclined tapered surface 17a to be shifted to the radial direction outside are engaged with an engaging inclined tapered surface 23a to mutually couple an arm side attachment 3 and a tool side attachment 5. When the cam member 17 is shifted from the locking position to the unlocking position, the engagement of the locking balls 13 with respect to the engaging inclined tapered surface 23a is released, and unlocking balls 15 which slide on a thrusting inclined tapered surface 17b to be shifted from the radial direction outside slide on a separating inclined tapered surface 23b to thrust the tool side attachment 5 from the arm side attachment 3.

Abstract:
PROBLEM TO BE SOLVED: To enable a sprue section resin being fed to the rear section (the root section of a screw) of a heating cylinder to always be favorably engaged with (involved in) the screw in an injection-molding machine system in which the sprue section resin having been taken out from a die is fed to the rear section of the heating cylinder under the shape as it is. SOLUTION: This injection-molding machine system feeds the sprue section resin under the shape as it is to the rear section of the heating cylinder, and reuses the sprue section resin as a material resin. In the injection-molding machine system, a sprue section feeding means which feeds the sprue section resin having been taken out from a die for each molding cycle to the rear section of the heating cylinder with the smaller diameter section of the sprue resin as the head is installed.

PROBLEM TO BE SOLVED: To efficiently perform a molded object unloading operation while securing safety for an operator by controlling the movement of a chuck according to the level of hazard to him, even when the operator stands near a resin molding machine and a molded object unloading machine. SOLUTION: This molded object unloading machine comprises the following components: (1) an image photographing member which is fixedly installed on the release position side of a main body frame and outputs photographed image data by photographing the image of the chuck moving in a release position; (2) a storage member which stores reference photographed image data relative to the reference movement of the chuck whose image is photographed by the image photographing member prior to a molded object unloading operation and real photographed image data relative to the movement of the chuck whose image is photographed by the image photographing member during the molded object unloading operation respectively; (3) an extraction means which extracts variations in the real photographed image data to the reference photographed image data; (4) a distinction means which determines in which region of a plurality of the regions set in a photographed image screen the extracted variations exist, and (5) a control means which controls the movement of the movable structure for moving the chuck according to the region where the determined variations exist.

Abstract:
PROBLEM TO BE SOLVED: To respectively dehumidify and dry amorphous resin pellets and crystallized resin pellets efficiently by one apparatus while achieving the miniaturization of the apparatus itself. SOLUTION: This dehumidification and drying apparatus is constituted so that its control means includes; a first dehumidification and drying mode for gradually heating amorphous resin pellets charged by controlling the heating of a first heating member in a divided manner while controlling the heating of the second heating member uniformly to crystallize them and heating the crystallized resin pellets CRP as a whole to dehumidify and dry them; and a second dehumidification and drying mode for uniformly controlling the heating of the first and second heating members to dehumidify and dry the charged crystallized resin pellets CRP.

Abstract:
PROBLEM TO BE SOLVED: To efficiently carry out work to change resin pellets to be dried by efficiently removing the resin pellets left in a drying container by simple work and to reduce apparatus production costs by efficiently removing the residual resin pellets without making the structure of an apparatus for drying the resin pellets complex. SOLUTION: An air flow with a required flow rate and a required flow velocity is supplied into the drying containers 7 and 9, and the residual resin pellets RRP adherent to the inside of at least the drying container 7 are removed forcibly by the pressure of the air flow.

Abstract:
PROBLEM TO BE SOLVED: To provide a resin pellet drying device which keeps the inside of a heating-drying means under a specified pressure-reduced state by surely closing the opening section by a simple structure, and reduces costs of the device itself by the simple structure. SOLUTION: A flexible opening/closing plate, and an opening/closing means having an opening/closing operation member are respectively provided. In this case, the flexible opening/closing plate has an opening section having approximately the same size as a transferring passage and a shielding section which shields the passage on the upstream side in the transferring direction of resin pellets in a feeding hopper and a discharging hopper, and is movably supported in the horizontal direction under an approximately air-tight state. The opening/closing operation member selectively locates the opening section and the shielding section on the transferring passage by moving the opening/closing plate in the horizontal direction.
