Definitions

  • the present invention relates to the technical field concerned with packaging, and more particularly it relates to the feeding of a conveyor with carton blanks, this conveyor being connected with a packaging machine.
  • Stacks of carton blanks are often placed into containers, from which they are taken out before they are transferred and placed on a conveyor.
  • the apparatus comprises a first belt conveyor on which the work units are placed groupwise in a standing posture closely in contact with each other, a second belt conveyor onto which the work units on the first are transferred while maintaining them upright, a holding bracket slippingly disposed on the first belt conveyor, and retaining means provided at the juncture of the first and second belt conveyors.
  • the holding bracket is adapted to be borne by friction so as to hold and push the work units upright in close contact and to slip on the first conveyor belt owing to the reaction from the work.
  • the retaining means comprises two holding pins which are kept retracted under the belts until the work has been completely transferred onto the second belt conveyor and then project above the belt conveyor so as to hold the work units from the rear to prevent them from falling backward.
  • the object of the present invention is to propose a process according to which the conveyor connected with a packaging machine is automatically fed with carton blanks taken out directly from a related bowl container.
  • a further object of the present invention is to provide an apparatus that carries out the process mentioned above and that incorporates simple technical features, thus offering reliability and functionality, and that also is versatile in its use.
  • the reference numeral 1 indicates a stack of carton blanks 2 packed into a bowl container 3 made of cardboard or the like.
  • Reference numeral 4 indicates a side of an operating unit 5 that is part of the subject apparatus.
  • the operating unit 5 has the task of taking a stack 1 of carton blanks out of the container 3 and to transfer this stack 1 onto a conveyor 6.
  • the conveyor 6 includes, for example, a conventional transport line comprising two parallel belts placed side by side and movable in the direction as indicated by the arrow A.
  • the containers 3 to be emptied are located on the conveyor 6, one after another.
  • the operating unit 5 is movable along guiding means 7, that are placed lengthwise over the conveyor 6.
  • the operating unit 5 is adapted for reciprocating from a blank stack taking out station 9 to a blank release station 10, where the stack of blanks just taken is positioned immediately after a stack of blanks previously fed to the conveyor.
  • the operating unit 5 is made to reciprocate by proper actuating means 8.
  • a slide 12 is associated to the side 4 of the operating unit 5 and is movable vertically.
  • the slide 12 is reciprocated by related actuating means 13 from a lowered position, where it clamps a stack 1 of carton blanks 2, and a raised position, located over the conveyor 6.
  • the slide 12 is equipped with means 14 for picking up the stack 1 that is to be lifted up and transferred.
  • the pickup means substantially include a clamp constituted by two jaws 15a and 15b, which are indicated as front jaw and rear jaw respectively, with respect to the advancement direction A.
  • the jaws 15a and 15b are operated by respective actuating means 16a, 16b so as to open and close.
  • the front jaw 15a is operated in such a way that it moves forewardly with a short oscillating stroke, over the conveyor 6.
  • the front jaw 15a is equipped with cutting means 17 fastened to its forward facing part and adapted to cut a corresponding wall of the container 3, as better described in the following.
  • pressing means 18 which are horizontally oriented and operated by proper actuating means 19 so as to move vertically.
  • the pressing means 18 pass through vertical slots 20 made in the jaws 15a and 15b (this can be seen in fig. 9).
  • Means 21 are provided for stopping a container 3 to be emptied at the picking up station 9.
  • These stopping means 21 are operated vertically by related actuating means 22, so that when they are in a raised position, they protrude over the horizontal surface of the conveyor 6.
  • the suction head 23 can be moved vertically by actuating means 24.
  • Additional suction means 25 are located along the conveyor and upstream of the previous ones, and they are adapted to engage a container 3 adjacent to the one undergoing.
  • Pushing aside means 26 operate at the picking up station and substantially include an ejecting member 27 adapted to reciprocate according to a direction that is transverse in respect of the conveyor 6, so that the empty containers are pushed aside (as shown in fig. 10).
  • the blank feeding process carried out by means of the apparatus described herein includes trasporting along the conveyor the containers 3 holding the stacks 1, one after the other, up to the picking up station 9.
  • the leading container 3 is stopped by the stopping means 21 which protrude over the transporting surface of the conveyor 6 (fig. 2).
  • Proper sensing means that are not shown in the drawings and that which are located at the picking up station 9, detect the presence of the stack 1 of blanks to be picked up.
  • the container 3 holding this stack 1 of blanks 2 is kept at the station 9 by the suction head 23 that has been moved to the raised position.
  • the slide 12 is then made to move downwards by the operating unit 5, up to a stack 1 pick-up position.
  • the pickup means 14 are then made to further move downwards, so that the jaws 15a, 15b insert into the container 3, up to its bottom.
  • the cutting means 17 secured to the front jaw 15a rip the side wall of the container 3 that is made of weak material (fig. 4).
  • the stopping means 21 are made to lower under the conveyor 6, while the suction head 23 keeps on gripping the bottom of the container 3, so that the container is held at the picking up station 9.
  • the stack 1 of blanks 2 picked up by the jaws 15a, 15b of the pickup means 14, is then trasferred to the release station 10 by the operating unit 5, that moves along the guiding means 7.
  • This stack 1 of blanks 2 moves along the conveyor 6 until it reaches the end of a row 11 of blanks which were previously fed to the conveyor 6 (fig. 5)
  • stopping means 21 are made to rise so as to protrude again over the transport surface of the conveyor 6.
  • the front jaw 15a of the pickup means 14 is first released, as shown with dashed line 23 in Fig. 5, so as to allow the blanks 2, previoulsy clamped by the pickup means 14, to slightly slant forward. (Fig. 6).
  • the pressing means 18 mounted in the underside of the slide 12 are made to lower so as to press on the stack 1 of blanks 2. Therefore the blanks 2, that are slightly slanting (as illustrated with dashed line in fig. 7), progressively go to lay on the row of blanks 11 that were previoulsy fed over the conveyor.
  • the rear jaw 15b is made to open while the slide 12 is moved upwards up to the risen position.
  • the suction head 23 releases the container 3 that was emptied, so that it can be pushed aside from the picking up station 9.
  • next container 3 from which the stack 1 of blanks 2 is to be taken out, is kept on the conveyor 6 by the additional suction means 25.
  • the container 3 already empty is instead pushed aside by the ejector 27 that operates moving along a direction transverse to the conveyor 6 (fig. 10).
  • the station 9 is in this way set up for a subsequent picking up.
  • the process herein described allows to perform automatically the feeding of a conveyor with stacks of blanks that are taken out directly from their related bowl container.
  • the trasferring of the container 3, holding the stacks 1 of blanks 2, to the conveyor 6 can be periodically carried out by an operator.
  • the operator loads the conveyor 6 with a number of containers, until the transporting line is full.
  • This automatic unit can be controlled by sensing means, that detect the containers being lacking on the transport line.
  • the magazine then automatically feeds the transport line at the picking up station.
