Furthermore, the machine comprises means for mounting the set-up holding strips one after the other on groups of elongated articles.

BACKGROUND OF THE INVENTION This invention relates to a machine for mounting holding strips, formed from foldable blanks, on elongated articles, preferably bottles.

Holding strips for bottles are already known. They are substantially trapezoidal or triangular in cross section. The known holding strips made from a blank of cardboard, however, do not ensure sufficient durability and a stiff connection between the bottles.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved holding strip of foldable material, particularly cardboard, which ensures an increased stiffness when mounted and thereby an increased holding stability on the elongated articles so that they are not movable relative to one another.

Another object of the present invention is to provide a machine for mounting the holding strips made of foldable material on elongated articles.

To attain these objects, the present invention provides a machine for mounting holding strips formed from a foldable blank on elongated articles, which comprises a magazine containing a plurality of folded-down blanks for forming holding strips; a setting-up station for the holding strips arranged beside the magazine; means for feeding said fold-eddown blanks one by one from the magazine to the setting-up station; means for consecutively setting up the folded-down blanks by exerting pressure on diagonally opposed edges of the folded-down blanks to obtain set-up holding strips having bottom, top and longitudinal side walls; means for mounting the setup holding strips individually on a group of elongated articles, and means for bending the middle portions of the longitudinal side Walls of the set-up holding strips v against the elongated articles.

"ice

Further features of the invention relate to the feeding of the folded-down blanks to the setting-up station, to purely mechanically setting up of the blanks and to mounting the set-up blanks or holding strips on groups of elongated articles.

DESCRIPTION OF THE PREFERRED EMBODIMENT FIGS. 1 to 5 of the drawings show a holding strip 10 made of foldable material, preferably cardboard, and formed from a suitably cut and scored one-piece blank providing, when set up, a bottom wall 11, a top wall 12 and two

longitudinal sidewalls

13 and 14. The individual walls are connected with each other on marked fold lines 15. The bottom wall 11 and the top wall 12 have lower and

upper holes

16 and 17, respectively, that provide for the passage of bottle necks 18 or of other elongated articles to be carried by the holding strip.

The set-up holding strip 10 serves to connect and hold a plurality of elongated articles which in the preferred embodiment shown and described are assumed to be bottles 19. FIG. 5 shows three bottles 19 engaged by a holding strip 10, the

holes

16 and 17 being so arranged that in engaged condition the bottles 19 have very slight or no gaps between them. The bottle necks 18 pass through the lower holes 16 and the upper holes 17 so that the edges 20 of the upper holes 17 in the top wall 12 find support on the collar 21 of the bottles 19. The edges of the lower hole 16 are preferably supported under tension on the wider region of the bottle neck 18 so that the entire holding strip 10 is stressed and the bottles 19 are connected to each other without the possibility of relative movement.

As can be seen from FIG. 4, arching or bending the

longitudinal side walls

13 and 14 inwardly provides for increased durability and rigidity of the holding strip. In the illustrated embodiment

longitudinal bends

22 and 23 extend approximately in the middle portion of the

side walls

13 and 14 along weakening lines in the form of for

example perforations

24 and 25 provided in the blank 3 shown in FIGS. 1 to 3. Advantageously, the

bends

22 and 23 find support on the bottle neck 18 thereby making a good bracing possible.

As shown in FIG. 1, the edges 20 of the upper holes 17 are shaped, so that a plurality of radial open-ended slots 26 define a plurality of resilient tongues 27 which resiliently engage the collar 21 of the bottle neck 18 from below and, due to their resiliency, make it possible to mount the holding strip 10 without damaging it.

FIGS. 6 to 14 show details of a machine for the fully automatic mounting of holding strips, in particular of the holding strips 10 according to FIGS. 1 to 5, on elongated articles.

The machine proposed by the invention operates in accordance with the fundamental idea of first setting up the incoming holding strips 10 which are folded down as shown in FIGS. 1 and 2, in a setting-up station 28, whereupon they have substantially the shape shown in FIG. 3, and then setting them on a group of bottles 19 which are held ready (FIG. Setting the set-up holding strips on the bottle necks 18 can be done either by lowering the set-up holding strip 10 onto the bottles 19, or, as in the illustrated embodiment, by inserting the bottles 19 from underneath into the set-up holding strip 10 in such a way that the bottle necks 18 pass partly through the

holes

16 and 17.

The folded-down holding strips 10 are arranged in a stack Within a magazine 29 of the machine and are removed therefrom through the bottomless lower end of the magazine 29 at equal time intervals by a reciprocating sliding plate 30 and fed to the setting-up station 28 (FIGS. 6 to 9). For this purpose, the reciprocating sliding plate 30 is equipped with a catch edge 31 which takes the respective undermost flat holding strip 10 out of the magazine 29.

The molding strip 10 which is still flat is carried along to a movable setting-up device 32 by the transverse motion of the reciprocating sliding plate 30. The settingup device 32 is of substantially bar-shaped configuration and has downwardly directed recesses 63 to accommodate the upper end of the bottles 19, as well as 21 depending nose 33 in which a small horizontal groove 34 is formed. The leading edge 35 (FIG. 7) of the fiat holding strip 10 enters this groove 34, and the trailing edge 36 which, in the set-up position of the holding strip 10 (FIG. 3) lies diagonally opposite the edges 35, finds support in the setting-up station 28 on at least one pivotable detent 37 which is raised when the reciprocating sliding plate 30 moves from the leftto the right-hand side in FIGS. 6 to 9, and is lowered so as to engage the edge 36- of the holding strip 10 when the reciprocating sliding plate 30 returns into its initial position thereby retaining the holding strip 10 in the position shown in FIG. 7.

Now the setting-up operation is initiated by exerting pressure on the diagonally

opposed edges

35 and 36 while the setting-up device 32 simultaneously moves along an arc indicated by a dot and dash line in FIGS. 7 to 9. The setting-up device 32 moves along a quarter circle the radius of which corresponds to the height of the

longitudinal sidewalls

13 and 14 of the holding strip 10. In this stage of the setting up operation, the diagonally opposed

edges

35 and 36 of the holding strip 10 are held in the position shown in FIGS. 8 and 9 by the setting-up device 32 on one side and the pivotable detent 37 on the other.

To carry out these motions the setting-up device 32 is actuated by a linkage system in the form of a parallelogram. This linkage system consists of an L-shaped arm 38 and

links

39 and 40. These

links

39 and 40 extend parallel to each other and are mounted pivotable at one end on the L-shaped arm 38, and on

stationary pivot bearings

41 and 42 at the other end. The effective lengths of the

links

39 and 40 and thus the path of motion of the setting-up device 32 are adjustable so that the machine m y b adap ed to different ize of holding strips 10,

In the illustrated embodiment, a group of bottles 19 is inserted from underneath in the stationary set-up holding strip 10 by a lifter 43 seen in FIGS. 9 and 12. During the insertion of the bottle necks 18 in the holding strip 10, synchronously controlled

pressing bars

44 and 45 which are movable by means of

swing arms

46 and 47 come to bear against the holding strip 10 in the area of the

perforations

24 and 25 and form the bends, the nominal height of the holding strip 10 being simultaneously shortened in accordance with the upward motion of the bottles 19. The top wall 12 of the holding strip 10 finds support on the facing side of the setting-up device 32 as the bottles 19 are inserted in the holding strip 10 while the upper ends of the bottles enter the recesses 63 in the setting-up device 32.

Furthermore, an upright support plate 64 is provided in the setting-up station 28 on which the setting-up device 32 and the holding strip 10 find support in the upright position of the latter (see particularly FIG. 9). This support plate 64 serves simultaneously as a limit to the rotary motion of the setting-up device 32.

The supplying of the bottles 19 to which a holding strip 10 is to be fitted takes place in a particular manner which will now be described. The bottles 19 are set by hand or in some other suitable manner onto a feed belt 48. Guide rods 49 are vertically adjustable on correspondingly constructed mounts 50.

The bottles 19 are fed by the feed belt 48 to the lifter 43 located under the setting-up station 28. This lifter 43 (FIG. 12) has a carrier plate which is intended to support, for example, three bottles 19 standing closely next to each other. According to FIGS. 7 and 12, the carrier plate has a horseshoe-shaped, preferably stationary raised edge portion 51 against which the incoming bottles 19 bear and which serves to align the bottles 19 on the carrier plate, i.e. on the lifter 43. The upward motion of the lifter 43 is controlled by swingable levers 52 which are connected to the stationary raised edge portion 51 and can by way of example actuate a photo-electric device. The control takes place in such a manner that the lifter 43 can only move upwards once all three bottles 19 are aligned on the lifter 43.

In order to lay the bottles 19 provided with the holding strip 10 off onto a discharge belt 53 (FIG. 7), a layingotf device 54 is provided which has laying-01f

arms

55 and 56 engaging the bottles 19 between the bottle necks 18 and under the holding strip 10 (FIG. 14). The layingoif device 54 is actuated together with the reciprocating sliding plate 30. The reciprocating sliding plate 30 has slide bodies 57 on which it can slide to and fro on guide rods 58. The laying-off device 54 is secured to both sides i of the slide bodies 57 by means of swing arms 59. The

free ends of swing arms 59 are provided with rollers 60 running on guideways 61. The guideways 61 are so designed that by the transverse motion of the reciprocating sliding plate 30 from left to right in FIG. 6 the laying-off device 54 is first moved along parallel to the latter. Once the holding strip 10 holding the bottles 19 is supported on the laying-off

arms

55 and 56, the laying-off device 54 moves on bevelled edges 62 of the guideways 61 obliquely downwards enabling the bottles 19 with the holding strip 10 to be laid off onto the discharge belt 53 (see FIG. 7).

The machine proposed by the invention enables a fully automatic mounting of holding strips on elongated articles, such as bottles, with a high efficiency and very little expenditure of labor.
