Definitions

  • the invention relates to a method for pressing on and locking a carrier made of cardboard or a similar suitable material bundling a certain number of objects to form a handling or sales unit, which is supported on the one hand on certain areas of the objects and on the other hand engages undercuts located on the objects with locking edges against which it is held by the stiffness and elasticity of the support structure, supported against the specific areas of the objects.
  • the support placed on the objects arranged on a support in accordance with the support structure is pressed against the specific areas of the objects with its elastically evading locking edges in one or more locking points behind the undercuts of the objects.
  • the invention also relates to a device for applying such a carrier to a corresponding number of objects, with a driven press-on head which can be moved against the objects arranged on a support according to the carrier construction, around the carrier placed on the objects with its locking edges into the arcing points to press behind the undercuts of the objects, which is further designed such that it engages with the carrier in the vicinity of the locking edges arrives and is provided with recesses for the entry of the parts of the objects projecting beyond the undercuts.
  • Objects are to be understood here to mean any type of body which is generally to be bundled in small numbers for the movement of goods and which, by virtue of its shape, permit the use of the bundling system determined by the described carriers.
  • the objects must on the one hand be provided with suitable surfaces against which the carrier can be supported and, on the other hand, have undercuts either themselves or on parts which are to be attached to the objects, behind which the carrier can be locked.
  • the carrier is generally a blank or pre-bonded blank consisting of cardboard or other suitable, preferably sheet-like materials, which is erected into a spatial configuration to produce a certain resistance, or it is already a corresponding molded part.
  • the blanks can be put together during assembly by means of a plug connection; if they are pre-connected, this is done for example by gluing, stapling or the like.
  • Blanks or molded parts not exclusively made of cardboard can also be welded or otherwise connected to one another to form a spatial shape.
  • the erected blanks or molded parts forming the carrier generally have openings with which they are first placed onto the objects and then by exerting pressure with their locking edges behind the undercuts of the counterparts stands are locked.
  • the carriers concerned are generally further distinguished by the fact that they generally do not completely span the objects to be bundled, but rather are applied to the objects on one side, where they are supported on specific contact surfaces of the objects.
  • Locking points are those points on the objects into which the locking edges of a carrier have to be pressed in order to enable them to be snapped behind an undercut. Since the carrier is supported on certain surface areas of the objects when it is pressed on, it has to be compressed by a certain amount in order to change into the locked state. This upsetting is usually associated with a further folding, through which the carrier, on the one hand, yields when pressed on, but, on the other hand, is additionally supported on the side walls of the objects.
  • a press-on head is used to press on and lock the carriers, which exerts pressure on the carriers in the region of their locking edges in order to bring the latter into their locking position behind the undercuts of the objects.
  • the objects to be bundled are containers which themselves do not have sufficient undercuts, the required undercuts are often provided behind closures, lids and the like.
  • the carrier system mentioned can advantageously be used, for example, for bundling bottles in one or two rows.
  • the straps can be on the bottle shoulders supported and can be locked behind the lower edges of the screw caps or crown caps, for example.
  • Carrier systems or carriers to which the method and the device according to the present invention are applicable are described, for example, in GB-PS 1 395 723 and in published European patent application 0 000 627.
  • the press-on heads used for the carriers shown there consist of a rigid unit which simultaneously locks the entire carrier on all objects forming a bundle by means of a fixed lifting movement.
  • Corresponding devices are described for example in GB-PS 1 427 510 and also in published European patent application 0 000 627.
  • the carriers offer to be attached and pressed on no difficulty on the items.
  • problems occur when the objects have larger dimensional deviations or when the objects are not pressed on a level machine base but in transport containers, the bottom surfaces of which are not always ideally flat, or on which dirt or foreign bodies are located can be located.
  • Such conditions occur practically with reusable bottles which, after being refilled, already in boxes, should be bundled in groups with the aid of the carrier system described.
  • the invention is therefore based on the object of providing a method and a device for pressing the described type of carriers onto a number of objects to be bundled, which allow certain dimensional deviations in the position of the locking points of the objects, without thereby affecting the quality of the bundle produced is affected.
  • this object is achieved according to the invention in that reference points on the object are located for each individual object of the bundle in a fixed distance relationship to the locking points, and in that the push-on path for the wearer in the area of each individual object depends on the position of the reference points of the object in question is determined such that the locking edges of the carrier just reach the locking points on the object in question.
  • the procedure is advantageously such that an area is provided in the section of a carrier that connects two objects in each case, which area is excluded from the direct action of the pressing forces.
  • the pressing can even be carried out for the individual object with a pivotable or articulated element which can be aligned with the tilted position provided.
  • a suitable design of the carrier it is not necessary that the pressing force be exerted in the entire locking area. Rather, it is sufficient if the pressure is only applied at certain points in the locking area.
  • the method can be applied on the one hand by the 'position of the reference points and the respective Aufdschreib is determined independently of the elements carrying out the pressing-on path, and on the other hand in such a way that the pressing-on path is inevitably determined or limited by the stop of the elements carrying out the pressing-on at the reference points of the objects. Which of the two procedures is used can depend on whether the available reference points are suitable for serving as attachment points for the press-on elements.
  • the claimed method is particularly suitable for carriers as described in GB-PS 1 395 723.
  • the object is achieved in that the push-on head consists of a number of push-on elements for pushing on a carrier in the area of an object, which are designed for the simultaneous execution of mutually independent push-on strokes.
  • Another solution basically also consists in the fact that, based on a carrier, the pressing-on operations in the area of the individual objects to be combined by this carrier take place individually and in succession, however, this procedure presupposes that the overall pressing stroke of the carrier or its locking edges is suspended the position after loosely placing the carrier on the objects is not too large in the locking position. If the press-on stroke is too large, the carrier could then be deformed too much in the areas between the objects.
  • a corresponding press-on head that meets these requirements of a small press-on stroke basically only needs one press-on element exist, which locks the carrier one after the other with the individual objects, and whose stroke for each of the objects is made dependent on the reference points determined on it.
  • Such a device can also have a press-on head which advances like a turret and has a plurality of press-on elements which can be successively brought into engagement with the individual objects. If you want to apply several carriers to parallel rows of objects at the same time, such turret heads can also be joined to form several on one axis.
  • press-on heads are more advantageous in which the press-on in the area of all of the objects to be encompassed by a carrier takes place simultaneously, but if necessary according to the invention with different strokes.
  • all push-on elements of a push-on head can be provided with individual drives for the push-on stroke, the stroke control of each individual element being activated actively by an associated sensor which detects the reference point or points of reference of the respective object or passively by means of elastic stroke limitation of the element and a stop against the reference points of the Subject can be done.
  • the entire press-on head with a stroke drive, which can be set to the largest press-on stroke to be expected according to the tolerances to be expected.
  • the individual press-on elements are arranged so that they can be brought to a standstill against a reference point before the end of the total stroke of the head.
  • the elasti The individual press-on elements in the press-on head can be supported, for example, by means of metallic, rubber-elastic or pneumatic springs.
  • the individual stroke control according to the invention of the individual press-on element should also be mentioned if, for example, two press-on elements form a rigid unit, which is tiltably mounted between these elements on a plunger, which in turn is elastically supported.
  • the tops of the closures i.e. the top ends of the items chosen themselves. This prevents the objects from having to go very deep into recesses in the pressing-on elements during the pressing-on process.
  • the push-on stroke must generally be dimensioned so generously that it tolerances in the distance between the reference points and the locking points, i.e. In the application example mentioned, dimensional tolerances in the amount of the bottle caps are taken into account.
  • the required safety for the size of the press-on stroke does not only depend on the tolerances that occur between the position of the reference points and the position of the locking points, it is also determined by the construction and material of the carrier and other dimensions of the objects.
  • the locking edges of the carrier are generally provided at the end of foldable tabs, which by the object when pressed onto the carrier in a more or less oblique or vertical position are pressed, in which they then finally snap behind the undercuts of the object.
  • This snapping finally takes place is determined by the elasticity of the material of the carrier, by the tolerance in the formation of the tabs and by the transverse dimensions of the object at the point in question, since it depends on them how steep the tabs for locking the locking edges must be erected.
  • the steepness of the erected tabs can depend, for example, on the diameter of the bottle mouth immediately below the closure.
  • the limitation of the press-on stroke in relation to the reference points must therefore include sufficient safety for the size of the stroke so that these tolerances are taken into account and that the carrier can always be locked with certainty.
  • the tolerances required for this are generally much smaller than those which are caused by differences in height in the objects and by differences in the position of the objects.
  • the tolerances to be taken into account during the press-on stroke are very small if the distance between reference points and locking points is small and the tabs carrying the locking edges are short and only carry out small distances during press-on.
  • the pressing-on elements only need to engage the support in places in the region of the locking edges if the support is sufficiently rigid chen. If the locking edges in the case of bottles, for example, encompass the entire bottle neck, it is generally sufficient if the press-on element is only provided with two web-like pressure surfaces, which run on both sides to be targential to the bottle neck. If these surfaces extend in the direction of the row of bottles to be bundled, continuous rails can also be used for pressing on an entire carrier, provided that these have sufficient elasticity in the area between the bottles to be able to adapt to different pressing strokes in the area of the individual bottles.
  • the inventive design of the press-on heads with individual adaptation of the press-on strokes of the individual press-on elements allows a relatively large freedom in the design and arrangement of the press-on heads.
  • the number of press-on elements of a press-on head will be adapted to the number and arrangement of objects to be bundled by means of a carrier.
  • the press-on head is designed for simultaneous, complete press-on into a plurality of carriers.
  • the press-on heads can be provided with devices for taking over, holding and / or putting on the previously erected supports.
  • additional devices for simultaneously folding two carriers between the press-on elements for different carriers can be, for example, expandable strips, rotatable eccentric discs or the like, which can be easily inserted between two rows of bottles or the like.
  • the press-on head shown in FIGS. 1 to 3 consists of a plate-like frame 1, which is provided in the middle with a support sleeve 2 for fastening the head to the (not shown) lifting drive of a device containing the press-on head.
  • the press-on head is provided with a series of press-on elements 3, which are guided through bores in the frame 1 by means of plungers 4 and with their upper ends above the frame 1 in a spring housing 5 are introduced.
  • 1-3 are pneumatic spring elements arranged in the spring housings 5 designed as cylinders, the construction of which is not shown in detail.
  • the individual pressing elements 3 can be pressed upwards by a certain distance independently of one another and independently of the stroke of the overall pressing head relative to the frame 1 of the head.
  • they are provided at their top with additional guide pins 6, which are also guided in holes in the frame. 1
  • the essentially solid pressing elements 3 are provided on their underside with a cylindrical recess 7 into which the heads of the bottles to be bundled by means of a carrier can enter when the carrier is pressed on.
  • the bottom of the recesses 7 serves as a stroke-limiting stop for the upper edges of the bottles and is therefore provided with a cushion disk 8 for shock absorption.
  • the press-on elements 3 are provided with bevels 9 in order to reduce engagement with the carrier in its areas lying between two bottles as much as possible.
  • the press-on head is provided on the side with holding plates 10 for receiving the pre-erected carrier. These holding plates extend along the row of press-on elements 3 and the pre-erected supports can be inserted between the holding plates 10 at the end.
  • the holding plates 10 are provided with angled portions 11, which already prepare the folding process of a carrier, which is carried out completely when the carrier is pressed on.
  • the holding plates 10 are connected to a spring device 12, for example way, when retracting the press-on head, a spreading of the holding plates 10 and thus allowing them to slide off the pressed-on carrier is permitted.
  • a pressing element is shown schematically, which is in engagement with a bottle head and has just locked a carrier located on the bottle neck. Parts corresponding to FIGS. 1-3 are designated by the same reference numerals in FIG. 4. In the spring housing 5, however, a helical spring 13 is indicated in FIG. 4 as an elastic counterpressure element for the pressing element 3.
  • the beer bottle 14 stands with further bottles in a row running perpendicular to the plane of the drawing, and the row of these bottles is bundled by means of a cardboard carrier 16 applied to the bottles.
  • the carrier 16 which is made from a flat cardboard blank and glued to an overlap point 17, has a lower wall 18 with punched through openings for the bottle necks, an upper wall 19 with through openings for the bottle head, from which foldable tabs 20 are punched, the ends of which are the actual locking edges 21 form which lock behind the lower edges of the crown cap 15, and two side walls 22 which are provided with inwardly directed folds 23.
  • These foldings can be prepared, for example, by the bends 11 of the holding plates 10 in the exemplary embodiment in FIG. 3.
  • the carrier is also provided with archable regions 24, which ensure that the carrier fits tightly against the bottle neck and represents an additional stiffening.
  • the carrier 16 Before the pressing-on process is carried out, the carrier 16 is loosely applied to the bottle necks, it being able to rest on the crown cap 15 with its tabs 20 which have not yet been folded up.
  • the carrier is then brought into engagement by a downward lifting movement of the entire press-on head with the individual press-on elements 3, which grip the carrier on the side of the tabs 20 and press it down with its top wall 19, the carrier pressing its bottom wall 18 against the bottle shoulders supports.
  • the side walls 22 lie close to the bottle neck by forming the folds 23 and the bulges 24 and are additionally supported there.
  • the press-on stroke of the press-on head is limited for each individual bottle when the respective press-on element with the cushion disk 8 bears against the top of the crown cap.
  • the distance between the pressure surfaces 25 of the press-on element and the cushion disk 8 is dimensioned such that when the press-on element 3 stops against the crown cork 15, the tabs 20 move precisely below the crown cork in their locking position in the undercut.
