Definitions

  • the invention relates to a device for automatically filling a substantially vertical magazine shaft for receiving a stack of cardboard blanks, in particular for cigarette packs, from which the cardboard blanks can be removed on the bottom, with a conveyor which ends at the discharge end of the magazine shaft and a horizontal conveyor line for receiving has several stacks of cardboard blanks and is provided with a drive that can be switched on via a scanner for the upper edge of the stack located in the magazine shaft and can be switched off after positioning a stack of stacks in the area of the magazine shaft, and with a support that can be pivoted into the area of the magazine shaft from one side for a stack of supplies carried by the conveyor into the area of the magazine shaft.
  • magazines are used to hold cardboard blanks in stack form, which, after removal from the magazine, are folded into corresponding packaging lines around objects to be packed.
  • the magazines are usually filled manually by taking a stack of cardboard blanks from a corresponding supply and inserting them into the magazine.
  • a very frequent refilling is required, which places a great strain on the operator, although other refilling or packaging processes are usually also to be carried out or observed by the operator . It can therefore happen more often that such a magazine runs empty, causing the entire packaging line to come to a standstill.
  • the object of the invention is therefore to provide a device for automatically filling a magazine shaft of the type mentioned, which is structurally simple.
  • the magazine shaft is delimited on the side adjacent to the discharge end of the conveyor by a guide wall beginning at the discharge end and on the opposite side by a wall which rises above the discharge end by at least the stack height, the scanner being slightly below in height the horizontal conveying path of the conveyor is arranged, the support and a further support which can be swiveled in from the other side can be pivoted transversely to the conveying direction of the conveyor and the supports after reaching the towering wall by a stack of stock conveyed by the conveyor into the area of the magazine shaft Area of the magazine shaft can be swung out.
  • the device is structurally simple and easy to couple with a conventional magazine shaft. Such a device is particularly suitable for cigarette packaging machines and the magazine shafts used in the process.
  • the illustrated magazine shaft 1 is provided in the exemplary embodiment as a double magazine shaft with a vertical middle wall 2 and vertical, lateral guides 4 arranged at a distance corresponding to the width of cardboard blanks 3 to be accommodated.
  • the middle wall 2 and the side guides 4 have at the lower removal end of the magazine shaft 1 support edges 5 for the respective stack 6 of cardboard blanks 3.
  • vertically extending guides 7 are provided on the front at a distance between the middle wall 2 and the side guides 4, while on the back one Rear wall 8 is provided, which can also be formed by the machine frame of the packaging machine for which the magazine shaft is used.
  • the magazine shaft 1 is formed, which receives the stack 6, from which the carton blanks 3 are removed from the bottom, in which the carton blanks 3 slide under the action of gravity in accordance with the removal and which has to be refilled from above.
  • a horizontal belt conveyor 9 Adjacent to the magazine shaft 1, a horizontal belt conveyor 9 is arranged on each side thereof, which has a belt 11 guided around rollers 10, one of the rollers 10 being drivable via a motor 12 and a clutch 13.
  • the upper run of the belt 11 runs over a support plate 14.
  • the lateral guide 4 ends essentially tangentially to the belt 11 or the roll 10, which is located adjacent to the magazine 1, so that a stack of stock 6 'fed by the belt conveyor 9' on the belt 11 and a bevel 15 slides along the guide 4 into the magazine shaft 1.
  • the rear wall 8 of the magazine shaft 1 also extends over the length of the material conveyor 9 with a height at least corresponding to an intended maximum stack height above the upper strand of the belt 11. Accordingly, an operator can stack stacks 6 ', 6' 'on the belt 11 side by side , the supply stacks 6 ', 6' 'being aligned with the magazine shaft 1 by pressing against the rear wall 8.
  • the magazine shaft 1 On the front side, the magazine shaft 1 also has a wall 16 in its upper region, which extends approximately from the height of the lower run of the belt 11 to the height of the upper edge of the rear wall 8 and over the width of the magazine shaft, so that it together with the middle wall 2 and the rear wall 8 forms a shaft open to the belt conveyor 9, the size of which is such that a supply stack 6 'can be received therefrom.
  • the two walls 8, 16 arranged essentially at a distance from one another are provided with a horizontal slot 17, while bearing bushes 18 for a shaft 19 are arranged on the outside of the walls 8, 16.
  • the two shafts 19 each carry a lever 20.
  • the two levers 20 have support plates 21 at the free end, which can penetrate through the slots 17 into the interior of the magazine shaft 1 and each extend over part of the shaft depth, for example over a third thereof.
  • the shafts 19 can be rotated back and forth via a corresponding drive (not shown) in order to pivot the support plates 21 into the magazine shaft 1 or out of it again.
  • An optical scanner 22 is arranged at a height slightly below the height of the upper run of the belt 11 such that it can determine whether the upper edge 23 of the stack 6 located in the magazine shaft 1 has fallen below the height of the optical scanner 22 or not.
  • the optical scanner 22 is coupled to the motor 12 and starts it when the former is the case.
  • the supply stacks 6 ′, 6 ′′ located on the belt conveyor 9 are conveyed in the direction of the central wall 2 of the magazine shaft 1 onto the support plates 21 and the supply stack 6 ′ finally comes into contact with the central wall 2 and after the support plates 21 have been withdrawn from the magazine shaft 1 on the stack 6 located in the magazine shaft 1.
  • the motor 12 can be controlled via a timing element, the time constant of which is dimensioned such that the supply stack 6 'is conveyed up to the middle wall 2. Instead, another optical scanner 24 can also determine whether the supply stack 6 'has reached the middle wall 2 and switch off the motor 12 at this moment.
  • a further optical scanner 25 can also be provided for the space between the supply stacks 6 ′, 6 ′′, which is used when the optical scanner 24 indicates that the supply stack 6 ′ has reached the middle wall 2, the motor 12 only stop when the next stack of 6 '' has reached its field of vision.
  • a further optical scanner 26 can be arranged in the area in which there is normally a supply stack 6 'in the waiting position for conveying into the magazine shaft 1, which emits an acoustic and / or optical signal for the operator when there is no supply stack 6' indicate that the belt conveyor 9 is to be filled with new storage stacks 6 ', 6' '.
  • the spaces between the guides 7 and the middle wall 2 and the guides 4 serve to enable easy manual filling of the empty or almost empty magazine shaft 1 without individual cardboard blanks 3 jamming or jamming.
  • a sliding conveyor which, for example, has a series of sliding walls, each of which engages a supply stack 6 ', 6' 'when they are inserted between them. This would make the optical scanner 25 superfluous, since only a certain stroke is carried out.
  • support strips which can be folded in or out of the magazine shaft 1 can be used for the respective storage stack 6 ', the width of which is smaller than the distance between the underside of the storage stack 6' and the upper edge 23 of the stack 6 must be 6 'when the supply stack is released.
