Definitions
- the invention relates to a device for transferring folding boxes to the conveyor of a packaging machine, including a receiver for taking over the folding boxes which are supplied to it in a pre-opened condition by suction means.
- the receiver oscillates between a position in which it takes over the folding boxes from the suction means and a position in which the fold ing boxes are transferred to the conveyor.
- a known device of this kind comprises two cam discs disposed in spaced relationship on a common shaft and holders for receiving the pre-opened folding boxes supplied to them by suction from a storage magazine in which the flat folding boxes are stacked, as well as a transfer bar arranged at the transfer station to the conveyor for lifting the folding boxes from out of the holders.
- the folding boxes are held at their rear edges by the holders and in their partly open condition in which they were delivered by suction are advanced to the transfer station where they are turned over to the receptacles of the conveyor.
- Another known device consists of a slidable member which is provided with a receiver and is oscillatable along a straight line between a takeover station to which the pre-opened folding boxes are delivered by suction from a storage magazine and a transfer station immediately above the conveyor of a packaging machine, in which position the folding boxes are pushed from the receiver by a depressing means and are transferred to the pockets of the conveyor.
- the known transfer devices are, on one hand, designed either for only one predetermined box size or are adjustable to other sizes only by an exchange of whole structural units, and on the other hand, are expensive and limited in performance.
- the invention has as its object a device for transferring folding boxes to the conveyor of a packaging machine, which device is characterized by a simple construction and high operative speed and safety and is so designed that without any exchange parts it may be easily and quickly converted to process various sizes and shapes of folding boxes within a wide range.
- the receiver comprises a receiving pocket formed by at least one pivot lever and adapted to receive the folding boxes with their side portions first outside the contact points of the pockets of the conveyor.
- the receiver is pivotable from its takeover position away from the conveying direction to its transfer position in the pocket of the conveyor.
- a transfer guide bar extending at an angle from the takeover station to the pocket of the conveyor. This guide bar directs the top side of the folding box during the advancement of the receiving pocket from the takeover position to the transfer position and in the transfer position pushes the folding box into a pocket of the conveyor.
- a guide bar for supporting the bottom of the folding box and also extending between the takeover station and the transfer station may form together a guide channel having the height of a folding box and by a simple height adjustment of the top bar may be adapted, within certain limits, to different folding box dimensions.
- a depressing means Arranged at the transfer station to the conveyor may be a depressing means, known per se, and operating in phase with the pivotal movement of the receiving pocket.
- This depressing means pushes the folding box from the receiving pocket of the transfer device at the transfer station and into a pocket of the conveyor. Since due to the pivotal movement of the pocket of the transfer device into the region of the pockets of the conveyor only minor slidable movements of the depressor are necessary, the folding box will not be damaged as is frequently the case in known devices.
- the lateral boundary forming an end wall of the receiving pocket of the transfer device may consist of a pivot lever arranged in spaced relationship to the guide bar and which pivots from the takeover position forming an obtuse angle with the guide bar through a angle into the transfer position forming an acute angle with the guide bar.
- the pivot lever, which engages one end wall of the folding box may preferably be of such a length that on its pivotal movement to the transfer position it is pivoted out of the path of the folding box and slides off of the respective folding box side before the folding box is received by a pocket of the conveyor.
- a further feature of the invention provides for a slide plate engaging the other end wall of the folding box. It forms the second boundary of the receiving pocket and is disposed opposite the first boundary at a distance which corresponds to the width of a folding box.
- the slide plate is adjustable in its distance from the pivot lever forming the first boundary of the receiving pocket.
- the two end wall boundaries of the receiving pocket holding the folding boxes may be formed by two pivot levers, whereby one of these levers may act as a slide plate.
- the pivot levers may be hingedly attached to opposite sides of the guide bar.
- the slide plate is provided with at least two contact surfaces arranged at an obtuse angle to each other and a transition therebetween. The contact surfaces are so arranged that at least one of them in the transfer position is disposed approximately parallel to the contact surface of the other pivot lever engaging the opposite wall of the folding box.
- the transfer device according to the invention is not only simple in construction but also operates safely at a high speed. Furthermore, the folding edges of the folding boxes, which on their way from the storage magazine to the transfer device are caused to stand up, are folded over in that the end walls of the holder pocket during the pivotal movement from the takeover position into the transfer position shift from one parallelogram position into the opposite parallelogram position and thereby accordingly deform the folding box placed between these boundaries. This eliminates to a large extent the natural tension inherent in the folding edges so that the folding boxes arrive at the pockets of the conveyor completely folded and substantially tension-free.
- FIG. 1 illustrates the transfer device in the takeover position
- HO. 2 illustrates the transfer device in the transfer position.
- the device for transferring folding boxes 1 to a conveyor 2 ofa not illustrated packaging machine consists substantially of two pivot levers 5 and 6 forming together a receiving pocket for holding the open folding box 1 and of a transfer bar 7 and 5 guide bar 8.
- the transfer device is arranged between the delivery end 3 of a storage magazine 4 and the conveyor of the packagingmachine.
- the pivot levers 5, 6 are pivotally mounted about horizontal axes of rotation 9,
- the pivot lever 6 which pivots about the axis of rotation 10 is rigidly connected with a rocking arm 11 of a four-bar chain which consists of a bar formed by the machine frame, a crank drive 13 rotatable about the horizontal axis of rotation 12 and a coupling link 16 pivotally connected at the axes 14, to the crank drive 13 and the rocking arm 11, respectively.
- the pivot lever 5 is in operative connection with the upper end ofa connecting rod 19 by means ofa rocking arm 17.
- the upper end of the connecting rod 19 is hingedly attached to the arm 17 at 18 and its lower end is attached at 20 to the arm 11 in the proximity of the axis of rotation 15.
- the receiving pocket formed by the two pivot levers 5, 6 oscillates periodically between the takeover position (FIG. 1) and the transfer position (FIG. 2) in conformity with the periodic oscillation of the rocking arm 11 of the four-bar chain.
- the folding boxes stacked in their flat condition in the storage magazine 4 are removed from the storage magazine by means of a suction device 21 arranged on one end of a pivot lever 23 which with its other end is rotatable about a horizontal axis of rotation 22.
- the suction device 21 always seizes the lowermost folding box at the delivery end 3 of the stack and moves it into the receiving pocket formed by the two pivot levers 5, 6 as illustrated in FIG. I.
- the suction device 21 engages the bottom of the precreased and cemented folding box and moves the box with one side wall along a bar 24 arranged inclined with respect to the stack of boxes. Thereby the folding box is caused to open.
- the operation of the suction device 21 is synchronized with the operation of the pivot levers 5, 6 forming the receiving pocket in such a manner that a folding box is introduced into the receiving pocket in the takeover position as illustrated in FIG. 1.
- the boxes are caused to stand up so that the bottom of the boxes engages the guide bar 8 while the suction device continues to move downward.
- the pre-opened folding box will be introduced into the receiving pocket formed by the two pivot levers 5, 6 and the same engage the side portions 25, 26 of the folding box,
- the latter After the folding boxes have been placed between the pivot levers 5, 6, the latter perform a pivotal movement and arrive at the transfer position illustrated in FIG. 2.
- the top of the folding box is engaged by the transfer bar 7 and the bottom of the folding box first slides over the guide bar 8 which extends up to the transfer position, and then slides off the bar 8.
- a depressing member 27 which operates synchronously with the pivot levers and is arranged on a pivot lever 29 pivotally mounted about an axis of rotation 28 engages the folding box and pushes it out of the receiving pocket and downward onto the conveyor.
- the conveyor for example a conveyor chain, is provided with pockets 30 formed between projections 31, 32 arranged at suitable distances from each other on the conveyor.
- the operation of the conveyor is synchronized with the pivotal movement of the pivot levers 5, 6 such that one pocket 30 is always then at the transfer station when the receiving pocket 5, 6 containing a folding box 1 is also at the transfer station.
- Extending along the top strand of the conveyor chain 2 is a horizontal guide bar 33 for supporting the bottom of the folding box placed between the projections 31, 32.
- Below the transfer device the conveyor 2 is reversed by means of a roller 34 journaled about a horizontal axis of rotation 35.
- the pivot lever 6 has substantially the form of a slide plate which engages the side wall 25 of the folding box located in the rear during the displacement, while the pivot lever 5 supports the front side wall 26 of the box.
- the pivot lever 6 has at its upper end two contact surfaces 36, 37 which engage the rear side wall 25 of the folding box and are so arranged that the contact surface 36 engages the folding box in the takeover position and the contact surface 37 is disposed about parallel to the contact surface of the pivot lever 5 engaging the front 7 side wall 26 ofthe folding box in the transfer position.
- the two pivot levers together with the guide bar 8 form a parallelogram-shaped receiving pocket corresponding in shape to the shape of the folding box which in its pre-opened condition is advanced by the suction means 21.
- the surface of the pivot lever 5 engaging the side wall 26 of the folding box forms in this position an obtuse angle with the guide bar 8 supporting the bottom of the folding box.
