Abstract: A cigarette stacking method is disclosed. It uses a stacking drum and a plurality of arranging drums near to its outer periphery, establishes different positions in the axial direction for cigarette pieces arranged by the arranging drums, stacks cirgarette groups in several layers in such a manner as to extend the end portions of the cigarette pieces successively in the axial direction on the stacking drum, and absorbs and maintains the cigarette pieces of each layer. A cigarette stacking apparatus is also disclosed.

Abstract: Packing paper receiving and folding method and apparatus are disclosed. The method has the steps of receiving and supporting a packing paper through an opening portion defined between suction arms of a suction ring; moving an arbor into the suction ring accompanying packing paper folded in a U-shape through the opening portion; effecting body folding of the packing paper using the arbor as a core member; and effecting flaps folding within the suction ring while properly maintaining the state of the body folding. The apparatus has a rotatable suction ring including a bracket, a pair of suction arms pivotable with respect to the bracket, the other ends of the suction arms defining an opening portion therebetween so that an arbor can enter therethrough, folding claws mounted on the insides of the suction arms and a bottom clamp positioned in the opening portion; a U-clamp provided within the suction ring for body folding; and a seaming clamp approaching to and departing from the arbor.

Abstract: A packing paper receiving and folding apparatus is disclosed. It has a rotatable suction ring including a bracket, a pair of suction arms axially supported at their one ends in a pivotable manner with respect to the bracket, the other ends of the suction arms defining an opening portion between them so that an arbor can enter from there, folding claws mounted on the inside of at least one of the suction arms, and a bottom clamp positioned in the opening portion to complete the suction ring having substantially an annular outer periphery; a U-clamp provided within the suction ring for body folding, a main presser for pressing an inner bag provided within the suction ring in such a manner as to be openable; and a seaming clamp approaching to and departing from the arbor.

Abstract: An arbor guiding apparatus is disclosed. It has a plurality of arbors arranged at least in two rows of arbors and in tandem on a rotary packing drum with respect to its axial direction. It also has a guiding device of the arbors in the radial direction. The guiding device includes supporting members axially supporting the arbors as well as connecting rods. One of the connecting rods include a threeway shaft at its one end, one way of the shaft being for engagement with a cam follower for guiding the arbor in the first arbor row while another way of the shaft being for engagement with a cam follower for guiding the arbor in the second arbor row. It further includes a device for effecting a relative movement of the arbors in the first and second arbor rows. The relative movement device essentially includes a pinion interposed therebetween.

Abstract: An apparatus for compressing cigarettes comprises a compression pocket having opposite open ends which comprises a pair of L-shaped compression members which are disposed in an opposite manner. Each member includes short and long segments which extend in an axial direction of a continuously rotatable drum, one of the members being movable in a tangential direction of the outer circumference of the drum, the other member being movable in a direction at an desired angle relative to said tangential direction. The apparatus also includes a device for moving the pair of L-shaped compression members in opposite directions using a rack and pinion combination system.

Abstract: A package forming apparatus comprises a pushing member which is capable of being inserted into a core member to form the bottom of a package by folding an end portion of the sheet material wound on the core member is driven by a driving mechanism. The driving mechanism comprises a slidable shaft provided on a rotary drum for movement in axial direction thereof, an arm member having one end secured to one end of the sliding shaft, a socket member having an intermediate portion rotatably supported at the other end of the arm member, a crank arm having one end secured to one end of the socket, the other end of the extension shaft being secured to the other end of the socket member and coupling member for snap coupling together the arm member and crank arm at a predetermined rotational position. Thus, the pushing member may be movable between the position where it faces with the core member and the position where it does not face the same.

Abstract: A cigarette arranging apparatus is disclosed. It has an arranging drum including a plurality of arcuate grooves arranged in its periphery, the grooves being extended in the axial direction and intimately contacted each other in the circumferential direction, and a plurality of cigarette receiving rollers near to the upper outer periphery of the arranging drum. The number of the cigarette receiving rollers corresponds to that of the arcuate grooves. The cigarette receiving rollers are arranged each to receive one piece of cigarette out of the plurality of cigarette pieces. The arranging drum and the cigarette receiving rollers are rotated in the opposite directions each other. The rollers are arranged to send cigarette pieces into the grooves successively from the forward grooves till the backward grooves without changing the motion speed to arrange cigarette groups intimately contacted each other.

Abstract: An improved packing container forming apparatus is disclosed. In the arbor turret type packing container forming apparatus, the improvement comprising a plurality of arbors arranged in tandem on a rotary packing drum in the axial direction, an aluminum foil suction ring for forming an aluminum bag with its one end closed in combination with the corresponding arbor by winding a sheet of aluminum foil around the arbor in the first rotary row, a package paper suction ring for forming a package paper bag with its one end closed in combination with the corresponding arbor by winding a sheet of package paper around the arbor in the second rotary row, and a shifting mechanism including a pair of racks and a pinion for shifting the arbors in the first rotary row to the second rotary row in a consecutive manner.

Abstract: A driving device for reciprocating a shaft along an axial direction thereof, comprises a reciprocating shaft drum for slidably supporting the reciprocating shaft along the axial direction thereof, a guide groove drum rotated relative to the reciprocating shaft drum and having an annular guide groove with an intersection on the circumferential surface thereof, and a driven member fixed to the reciprocating shaft and engaged with the guide groove. The driven member includes a cam follower and a boat-shaped member rotatable about a shaft extending from the driven member to the guide groove, the boat-shaped member has a cam roller rotatable about another shaft extending from the driven member to the guide groove, and the guide groove has a cam follower guide path engaged with the cam follower, a cam roller guide path engaged with the cam roller and a boat-shaped member guide path engaged with the boat-shaped member at the intersection thereof.
