Patent name Product packaging machine working wheel Patent applicant Kyrgyz Joint Stock Company Principal Applicant Address Bologna, Italy inventor Mario Spatafora; Alver Taki Application (patent) No. 200410070417.1 Date of application 2004.08.02 Award Certification Date Approval Notice No. 1579885 Auditing Notice Date 2005.02.16 Manual CD-ROM D0507 Main Classification Number B65B19/00 Classification Number B65B19/00; B65B19/02 Sub-item Original Application No. Priority Abstracts Packaging Machine (1) Working wheel, with: An annular barrel (3); a plurality of through-grooves (8) carried by the annular barrel (3) each accommodating an associated product (21); a first drive means (18) progressively rotating the annular barrel (3) to make grooves (8) Feeding along a circular path (P) through the loading position (23) and the unloading position (25); the first and second propulsion devices (53, 54) at the loading position (23) and the unloading position (25) ) Engage with the corresponding groove (8); second electric drive means (56, 47) to advance the pushing device (53, 44) towards the retracted stop position inside the annular barrel (3) and through the groove from this position ( 8) Radial reciprocating motion; first safety device (58) when at least one advances When the device (53, 54) is engaged with the groove (8), the rotation of the annular cylinder (3) is prevented; and the second safety device (59; 80) prevents the propulsion device (53, 44) when the annular cylinder (3) rotates Move from retracted position. Slaves 1. A working wheel for a packaging machine (1) for packaging products (21), said working wheel (2) comprising: a fixed central body (5), said central body having a longitudinal axis (4) An annular cylinder (3) coaxial with the longitudinal axis (4) and surrounding the central body (5); a plurality of continuous slots (8) carried by the annular cylinder (3) and each The through slots are all for accommodating the related product (21); a first drive means (18) for stepwise rotation of said annular drum (3) about said longitudinal axis (4) so ​​that said Slots (8) are fed along a circular path (P) which extends through the loading position (23) and the unloading position (25) to respectively load and unload the product (21); first and second advancements Means (53, 44) carried by said central body (5) and for engaging with said slot (8) at said loading position (23) and said unloading position (25), respectively; and a second drive Means (56, 47) for urging said propulsion means (53, 44) towards respective retraction stop positions in said annular cylinder (3) and from said position through said respective slots ( 8) Perform a corresponding roughly radial reciprocating operation The working wheel (2) is characterized in that at least the second drive means (56, 47) is an electric drive means; and the working wheel comprises a first safety means (58) for the advancement thereof When at least one of the devices (53, 44) is engaged with the corresponding slot (8), the annular cartridge (3) is prevented from rotating about the longitudinal axis (4); and the second safety device (59; 80) In order to rotate the annular barrel (3) about the longitudinal axis (4), the propulsion means (53, 44) are prevented from moving from the corresponding retracted position.
