Description

Method and device for fitting a label holder

on bottle necks.

  The present invention relates to a method and a device

  tif to apply a label holder on bottle necks, label holders

  quette each comprising an open elastic ring with means

for hanging a label.

  Label holders of this type are known from the application for

  French Patent No. 2,705,483. According to this request, the elastic ring

  open from the label holder on the outside, in a posi-

  roughly diametrically opposite to its opening, a rod which

  is provided at its free end with a rounded head, more particularly-

  a hemispherical head, and at least two opposite flexible lugs

  wheat which hold on the stem a label with a hole for

its threading on the rod.

  Label holders of this type have proven themselves, but

  are currently installed manually on the necks of bou-

  teilles, which limits their use to promotional campaigns

  concerning only a limited number of bottles.

  The present invention relates to a method and a device for laying

  such label holders on bottle necks, making it easy to

  proud and accelerate, even automate this installation and reduce its cost

  in order to promote the dissemination of these label holders and

generalize use.

  According to the invention, with a view to fitting such a label holder

  on the neck of a bottle, one engages a bottle under a head of ex-

  pansion which covers the neck of the bottle and has at its upper end

  a maximum transverse dimension at most equal to the diameter

  be inside the relaxed open ring of the label holder and at its ex-

  lower end, located below the bottle ring, a

  transverse dimension greater than the diameter of said ring. We-

  pledge the ring of a label holder from the top on said head. Wave-

  places said ring down on the head to cause its expansion and, at the lower end of the head, its descent from the latter and

  its engagement and tightening by elasticity on the neck of the bou-

  teille. Preferably, the expansion head is fixed to a support by a radial clip. In this case, we engage the label holder ring

  on the expansion head in an angular position such that, the opening

  ture of the ring is located substantially at the right of the radial attachment of

  the head and allows the expanded ring to cross ladi- without problems

  ties you up when it comes down on your head.

  To automatically ensure angular positioning

  correct of the ring with respect to the radial attachment of the expansion head

  sion, we bring the label holders with their labels to the head

  expansion from the side opposite to said radial attachment by making them

  sliding on a rod inclined to the vertical in a way

  re that the label holders, under the effect of the weight of their labels, all adopt the same angular position, the labels hanging towards

the bottom.

  Preferably, the ring of each label holder is moved downwards on the expansion head by exerting on the ring a downward push in two positions substantially opposite with respect to the

expansion head.

  Advantageously, said thrust is exerted on the ring in two angular positions offset substantially by 90 on each side and

the opening of the ring.

  The device for implementing the laying process includes

  takes an expansion head with vertical axis, a system of pushers

  can be placed vertically back and forth relative to the head, outside

  laughing at the latter, and means for bringing the label holders

  one by one at the upper end of the expansion head.

  Preferably, said means comprise a label holder loader and a label holder distribution system one to

  one from the charger to the expansion head.

  Preferably, the expansion head is installed in a fixed position by being connected to a support by a radial attachment. The label holder charger in this case comprises a rod on which the label portfolios fitted with their labels are threaded by their rings,

  said rod being connected to the head horizontally or inclinedly

  born in relation to the vertical, in an angular position which, compared to

  port to the axis of the head, is substantially opposite to the position of the atta-

radial che of the latter.

  Preferably, the expansion head has a frusto-shaped

  nique, is installed above a bottle conveyor, in posi-

  fixed position, above the bottles advanced by the carrier, and is extended down to the bottom of the bottle rings by two opposite guide tabs between which the necks of the

  bottles advanced by the transporter.

  In this case, the label holder distribution system a

  to one as well as the tappet system are controlled synchronously

  me with the movement of advancement of the bottles on the conveyor.

  Referring to the appended schematic drawings, we will describe

  re below in more detail the label holder intended to be applied according to the method and by the device according to the invention, as well as the

  structure and mode of operation of this device; on the-

  sins: Figure 1 shows a label holder used in accordance with the invention, with its label; Figure 2 shows the label holder of Figure 1 placed on a bottle neck; Figure 3 is a side elevational view of the device

  label holder installation, installed above a bottle carrier

teilles;

  Figure 4 is a front elevational view of this device.

  According to Figures 1 and 2, a label holder 1 used to attach

  expensive a label 2 at the neck 3 of a bottle 4 comprises an open ring 5 comprising, in a position opposite its opening 6, a

  rod 7 which has at its free end a rounded head 8, in this case

  ment a hemispherical head. Two opposite flexible lugs 9 in form

  me of whiskers also protrude radially on the rod 7, to

  the location of the connection of the head 8 to the rod 7.

  The label holder as described is advantageously made

  in one piece by plastic molding.

  Label 2 includes, for its attachment to the label holder-

  te 1, a hole with a diameter slightly greater than the diameter of the head 8.

  The label 2 can thus be engaged by its hole on the rod 7

  then being retained on the latter by the pins 9.

  The device for fitting a label holder 1 according to FIGS. 1 and 2 on the necks 3 of bottles 4 comprises, according to FIGS. 3 and 4,

  essentially an expansion head 10 installed in a fixed position above

  above a bottle conveyor 11, and means 12 for passing the label holders 1 provided with their labels 2 one by one from top to bottom on the head 10 when a bottle 4 has been brought into

  the direction of the arrow 13 by the conveyor 11 below the head 10.

  The head 10 essentially has the shape of a trunk of rib

  fixed by a fastener 14 in the form of a radial arm to a support 15

  placed in a fixed position above the conveyor 11. The head 10 has at its upper end a diameter less than the inside diameter

  of the relaxed ring 5 of the label holders 1 and at its lower end

  re a diameter greater than the outside diameter of the neck 3 of the bou-

  head 4. The head 10 is extended downwards by two guide tabs.

  ge 16 diametrically opposite in angular positions such that the necks 3 of the bottles 4 can pass between the two legs

  guide 16, as shown in Figure 4. At the upper end

  the head 10 is connected a guide 17 of circular section which

  extends vertically upwards to join, after a bend of

  about 60, a fitting 18 into which a charger can be fitted

  19 on which is threaded a multitude of label holders 1.

  Means not shown, for example of the screw type, are provided at the level of the guide 17 and / or of the connector 18 for dispensing one to

  one, at the head 10, the label holders 1 located on the charger 19.

  It is recognized in FIG. 3 that the fastener 14 by which the

  head 10 is connected to the support 15, on the one hand, and the connector 18 and the char-

  geur 19 for the label holders, on the other hand, lie in relation to

  the axis of the expansion head 10 in diametrically opposite positions

  installed, the fastener 14 being located in the direction of transport 13 of the bou-

  through the conveyor 11 upstream of the head 10 and the fitting 18 and the charger 19 downstream of the head 10. Thus, under the weight of the labels

  2, the label holders 1 threaded onto the charger 19 all adopt the same

  me angular position on the guide 17 and therefore all arrive in the same

  me angular position on the head 10, namely so that the label 2 is in a diametrically opposite position relative to

  the fastener 14, so that the opening 6 of the ring 5 of the label holders-

  te 1 is located to the right of the attachment 14 of the head 10. Therefore, during

  the expansion of the ring 5 during the downward movement of the carrier

  te-label 1 on the head 10, the ring 5 can cross without problem

the clip 14.

  The means 12 for moving the label holders up and down

  te 1 on the expansion head 10, to cause the expansion of the an-

  5 and at the lower end of the guide lugs 16 extend

  with the expansion head 10 downwards, release the rings from the head

  1 to allow them to tighten by elasticity on the neck of the bou-

  head 4 located below the head 10 comprise two pushers

  evenings 20 being in diametrically opposite positions relative to the head 10, corresponding to those of the guide tabs 16

  Each pusher 20 is mounted on the lower end of a lever

  voting 21 whose upper end is articulated by an axis 22 hori-

  zontal on a slide 23 which is mounted movable in translation on two vertical columns 24 of the support 15 so as to be able to be driven in a vertical movement back and forth under the action of an actuator not shown, by example a cylinder. Both arms 21

  are pressed against each other by a tension spring 25 and

  each also tries, at mid-length, a roller 26 which rolls on a cam 27 integral with the support 15 and shaped so that during the vertical movement of the pushers 20, the latter follow the profile

  tapered head 10, but without rubbing on the latter.

  We will describe below a cycle of laying a label holder on the neck of a bottle, starting from the end of the cycle of laying a label holder on the previous bottle; the two pushers 20

  are then in the lowered position shown in dashed lines on the

  Figures 3 and 4 and a label holder 1 for the next bottle is located at the upper end of the expansion head 10.

  By the actuating cylinder not shown, the two pushers

  evenings 20 are moved up, along the head 10, before being

  spaced apart, a short distance above the upper end

  head 10, to drop the label holder down

  10 after having driven it up a short distance. The ca-

  my 27 have for this purpose a boss controlling this spacing of the two pushers 20. Then, the vertical movement of the pushers

  is inverted, so that these push down the holder

  label 1 resting at the upper end of the head 10, which pro-

  evokes the expansion of the ring 5 of the label holder 1 and allows the an-

  neau, thanks to its opening 6, to cross the fastener 14 of the head 10.

  The ring 5 then slides on the guide tabs 16 located on either side of the neck of the next bottle 4, meanwhile brought below the expansion head 10. At the end of the descent movement of the

  pushers 20 pushing in front of them the ring 5 of the label holder 1, the an-

  neau 5 descends from the guide tabs 16, at the lower end of the latter, and engages by tightening by elasticity on the neck of the

bottle 4.

  Of course, an order is provided to synchronize

  the different movements concerning the supply of 4-in-bottles

  below the head 10 by the conveyor 11, the upward movement

  and descent of the pushers 20 and the distribution one by one of the holders

quette 1 from the magazine 19.

  It should be noted that the embodiment represented

  felt and described has been given by way of illustration only and not limited to

  and that many modifications and variations are possible within the scope of the invention, both with regard to the structure of the

  device for fitting the label holders than the label holders themselves

  my. The latter may for example bear, not only labels

  quettes, but also for example booklets.
