Definitions

• the present invention relates to a device for taking articles from a magazine and transferring them to a conveying line.
• a specific need encountered in the field in question is the possibility of a quick and easy change of the size of the articles to be transferred.
• the main object of the present invention is to resolve the above problem by proposing a device, which allows simple and rapid taking over of articles from a magazine and transferring of the just taken articles to a conveying line.
• Another object of the present invention is to propose a device, whose structure is of simple, and whose operation is reliable and the use versatile.
• a device for taking articles from a magazine and for transferring the just taken articles to a conveying line characterized in that it includes a drum, rotating about an axis arranged crosswise to the conveying line, in a direction concordant with the forward movement direction of said conveying line; a series of gripping groups rotatably carried, regularly spaced apart, at the edge of said rotating drum and driven to rotate in the opposite direction and in a suitable step relation with respect to the rotation direction of the rotating drum, so as to perform a complete turn between a position, in which a single article is taken from a magazine and a position, in which said article is transferred to said conveying line,- gripping means carried oscillating by said gripping groups for gripping said articles; means for maintaining said gripping means in a configuration substantially radial with respect to said rotating drum.
• Figure 1 is a schematic lateral view of the proposed device for taking articles from a magazine and for transferring the taken articles to a conveying line;
• Figure 2 is a schematic view of operating means of the proposed device
• Figure 3 is a section view of the proposed device, taken along the plane III-III in Figure 1;
• Figures 4A, 4B, and 4C are schematic lateral views of the proposed device, during subsequent working steps.
• the reference number 1 indicates the device for taking articles 2 from a magazine 3 and for transferring the articles 2 to a conveying line 4, which moves continuously, in the direction indicated by arrow A.
• the conveying line 4 has a series of transversal sectors 5, regularly spaced apart, aimed at defining respective seats for housing the articles 2 to be conveyed.
• the articles 2 to be withdrawn, generally in flat form, are packed arranged in the magazine 3 , suitably inclined with respect to the horizontal plane of the conveying line 4.
• the taking and transferring device 1 includes a rotating drum 10, rotatably carried by a shaft 11, so as to rotate in a direction indicated with arrow B, concordant with the direction A of the forward movement of the conveying line 4, about a horizontal axis, which is transversal to the forward movement direction of the conveying line 4.
• the drum 10 carries gripping groups 12, which are regularly spaced apart along the drum edge and which are aimed respectively at taking single articles 2 one by one from the magazine 3 and at transferring the articles 2 to 5 the conveying line 4.
• the gripping groups 12 include respectively an arm 13 rotatably mounted on the edge of the drum 10, on a pin 14, whose axis is parallel to the rotation axis of the drum 10 :
• Pulleys 15, on which a transmission belt 16 is mounted, 15. are fastened to the pins 4 of the arms 13.
• the pulley 15 of only one of the above pins 14 allows coupling with another transmission belt 17, which winds on a stationary pulley 18, arranged in coaxial relation with the drum 10 (see Figures 2 and 3) .
• a suitable transmission ratio in the amount of 3:1 in the shown case, is determined between the pulley 15 and the stationary pulley 18, so as to make each arm 13 perform as many turns as there are gripping groups 12, within one complete rotation of the drum 10.
• the arms 13 of the gripping groups 12 perform three complete turns, in the direction opposite to the rotation direction B of the drum 10, within one complete rotation of the drum 10.
• annular body 20 is mounted, oscillating on a pivot 19, 30 on each arm 13 , suitably spaced apart from the pin 14.
• a stem 21 is guided, sliding freely, within the annular body 20.
• the stem 21 is hinged on a relevant fulcrum 22 to the drum 10, close to the shaft 11.
• the body 20 carries a projecting bar 23, geometrically coupled with a suction cup gripping member 24.
• the position of the suction cup gripping member 24 is suitably adjustable on the bar 23, in relation to the size of the articles 2 to be transferred. In the following, operation of the described device will be explained beginning from the step, in which an article
• the arm 13 of the relative gripping group 12 is arranged in a position substantially radial to the rotating drum 10 and perpendicular to the articles 2 arranged in a pack in the magazine 3.
• the suction cups gripping member 24 removes the first article 2 of the above pack of articles situated in the magazine 3.
• the rotation of the drum 10 causes the simultaneous rotation of the arms 13 of the gripping groups 12 in the direction C opposite to the rotation direction of the drum 10.
• This rotation is determined, with the suitable transmission ratio, by the transmission belt 17, mounted on the stationary pulley 18, arranged in coaxial relation with the drum 10.
• the rotation of the arm 13 causes the stripping of the article 2, gripped by the suction cups gripping member 24, from the magazine 3 and brings it close to the drum 10 ( Figure 4A) .
• the stem 21, sliding inside the annular body 20 causes the oscillation of the annular body 20 with respect to the arm 13 , so as to maintain the orientation of above body 20 substantially radial and consequently, the tangential orientation of the just taken article 2 with respect to the rotating drum 10.
• the arm 13 performs gradually a one turn rotation, while the combined oscillation movement of the body 20 maintains the just taken article 2 in the above mentioned tangential orientation with respect to the rotating drum 10, as seen in Figures 4B and 4C, which show two subsequent moments of the rotation.
• the arm 13 of the gripping group 12 with the taken over article 2 is brought again to the position substantially radial to the rotating drum 10.
• the article 2 is transferred to the conveying line 4 (see again Figure 1) .
• the proposed device fulfills the object to take articles from a magazine and to transfer them to a conveying line in a simple and rapid way. It is to be noted that the device allows to change the size of articles to be transferred, in an easy and rapid way, since it is possible to adjust the position of the suction cups gripping member 24 without acting on other means of the same device.
