DESCRIPTION:
BRIEF SUMMARY
The invention relates to a method and an apparatus for compiling deformable, substantially cylindrical bodies, particularly tampons, and for packing them.
During manufacturing of cylindrical bodies, like tampons, the bodies discharged from the manufacturing machine are generally led to a shaking or vibration compartment in which the bodies being parallel to each other and superposed are aligned in a row at the bottom of said compartment transverse to the longitudinal direction of the bodies. Thereafter, this series of bodies is directly shifted into a package box by means of a slide. But this cyclic operation is relatively slow so that the packing efficiency per time unit is low.
It is an object of the invention to provide a method and an apparatus of the above-mentioned type by which the bodies discharged from the manufacturing machine can be compiled in such a manner that a substantially enhanced packing efficiency at substantially full automatic operation can be achieved.
The method according to the invention for compiling substantially cylindrical bodies, particularly tampons, and for packing them, comprising vibrating said bodies being substantially parallelly stacked and superposed to each other and aligning at least one row of adjacent parallel bodies, whereafter this row is shifted in longitudinal direction of said bodies and fed to a reception means, is characterized in that said row of aligned bodies is placed in a substantially parallelepipedic magazine through a narrow side of said magnetic adapted to the length of said bodies, that said magazine is substantially spaceless charged with a plurality of body rows, whereafter said magazine is transferred to a magazine discharge station and positioned below a substantially similar transfer magazine, that thereafter the bodies are shifted from said magazine upwardly into said transfer magazine which is then moved in transverse direction through a reception space for said bodies with its narrow side being adapted to the length of said bodies which enter said reception space by gravity and are divided into streams moving downwardly into the region of two or more adjacent discharge devices from which said bodies compiled to predetermined groups are shifted at the same time into cups of a cup conveyer.
The subject matter of the invention also comprises an apparatus for carrying out said method having a shaking compartment which is supplied by the manufacturing machine of the bodies, which shaking compartment is open in its bottom area for the passage of a slide which is transversely movable to said compartment, each of the lowermost rows of bodies being cyclically shiftable into a reception means; said apparatus is characterized in that said reception means is a substantially parallelepipedic magazine being chargeable without interstices with a plurality of body rows through a narrow side adapted to the length of the bodies, wherein said magazine is provided with an adjustable bottom which is forceably retained in the side portions of said magazine, and that said magazine is suspended with its upper side in a frame structure receiving a row of magazines being tandem joined below a pressure stamp, the pressure surface of it corresponding to the surface of the inner cross section of said magazine and being movable against said magazine in fixed-cycle operation to press one body row into said magazine at a time.
According to a further embodiment of the invention, the apparatus is characterized in that parallel tracks are provided for receiving said loaded magazine transferred from said frame structure, that at the upper side of the tracks two transfer magazines connected to each other are each transversely shiftable between a first position in which the bodies are moved out of said magazine upwardly into said associated transfer magazine, and a second position in which the loaded transfer magazine discharges the bodies to a reception means being mounted at the lower side of said track and through which the bodies can be supplied to a plurality of adjacent d
