The invention relates to a labeling machine eit a label -Greifstation and with a an article for labeling "station and past moving conveyor _o In particular, the invention relates to an automatically operating machine for applying a label or multiple labels to objects, the check sequentially given on a Move away «

A machine according to the invention is generally suitable and / or designed to apply adhesive labels (self-adhesive labels) attached to a continuous carrier strip and fed to the machine to objects, although the machine can also be used with equal success for the application of other types of labels can _p be fed to her either in tape form or from a funnel «

The invention is based on the object of a labeling machine to create, with which it is possible to precisely place adhesive labels on voted areas of objects regardless of the location of these areas on the objects and regardless of their attach outer shape. It should be ensured that the adhesive labels, either partially or completely are detached from their Tragstrelfen at the label gripping station, are to be attached exactly aligned to the objects, with it

It is irrelevant whether the carrier strips of the label gripping stations trains in a horizontal, vertical or inclined plane be directed. Furthermore, the labels should be precisely aligned and held at the label gripper station »even if they are completely detached from the carrier strip feeding them to the gripping station.

The solution to this problem serves - in a few words < a labeling machine with a label dispenser, from which either completely or partially free labels on one Rotary head arranged attachment members are supplied. the Labels may or may be attached to the attachment links a stationary label holder which has two parts which are spaced apart and between which the attachment members pass, the labels being held in an exact position on these parts »if the labels are fed to such a label holder, the attachment members strip successively the precisely aligned labels from this before they are sent to the labeling station for attachment to the itself bring objects moving along a given path. The attachment members are configured and aligned on the label table to hold the labels thereon guide on a path that is parallel to the path of movement of the objects, and at the same speed as the objects, so that the labels can be applied precisely to predetermined areas of the objects.

Fig. 14 shows the schematic diagram of the circuit for controlling the printing devices of Fig. 13

Fig. 15 is a partial view of a modified embodiment of devices for aligning the labels.

The labeling machine has a frame or frame 10 on which a conveyor 11 of conventional design is mounted, which leads the objects to be labeled successively to the respective stations and devices and past them through the machine. These contain a screw conveyor at the input end of the machine 14, to which a check-out station I? in which the objects on the conveyor 11 are brought into a certain position after they have been released from the screw conveyor, so that they are successively precisely aligned with respect to the attachment members 16 which apply the labels to the objects 12 in the labeling station 17. The labels are attached to two label dispensers 20. fed to the 16 at the gripping stations 60 _o The labels applied to the objects in the labeling station 17 are securely attached to the objects in a subsequent pressing station 18. During the way from the screw conveyor 14 to the labeling station 17 and past it and to the pressure station 18, the lower run of a pressure belt 19 arranged on the conveyor 11 presses on the upper ends of the objects 12, so that these on this part of their way through the machine between the Lower run of the belt 19 and the conveyor 11 are held.

The screw conveyor 14 is of known design and rotatable so stored on one side of the path of the objects that it is parallel to the input-side portion of the conveyor. As Flg. 9 shows, the auger 14 is disengaged from the main shaft 25 driven, which extends the length of the machine and continuously driven by an electric motor 26 at a speed of three revolutions per working cycle of the machine

309831/0503

is, the drive pulley 28 via a belt 27 with a Pulley 29 is connected to a shaft 30 arranged in alignment with the main shaft 29. On the drive side, the shaft 30 is connected to the main shaft 25 via an electrical coupling Breas member 31 which is designed so that when the coupling part 8 is actuated to release the shaft 30 from the main shaft 29, the braking part is simultaneously connected to the main shaft 25 Effect comes to stop their rotation. When the main shaft 25 is stopped, the motor 26 rotates with this arrangement, the shaft 30 continues.

The main shaft 25 is provided with a drive wheel 35, the over a chain is connected to a wheel 36 on one end of a shaft 37 'which is parallel to the main shaft 25. On the other end The shaft 37 has a drive wheel 38 which is connected via a chain to a wheel 39 which is connected to the shaft the screw conveyor 14 drives connected gear transmission. The aforementioned, the screw conveyor 14 to the main shaft 25 connecting points are designed so that the screw conveyor has a speed of one revolution per working cycle of the machine is given. If the machine is set for labeling 200 objects / minute, the screw conveyor 14 rotates with it 200 revolutions / minute to give the objects a predetermined pitch so that they are in a timed relationship to the devices operating at this labeler speed.

The objects arrive on their way from the screw conveyor 14 12 first in the alignment station 15. Here, the objects are removed from their positions in which they are carried on the conveyor 11 the screw conveyor 14 were left, placed on the conveyor 11 in positions in which they the Etlkette attaching links, precisely aligned with respect to this, supplied so that an exact application of the labels to the objects is ensured. Like Flg. 1 shows there are two in the alignment station Straightening units provided, one of which on each side of the Conveyor 11 lies and clamping jaws 46, 46 * in opposing arrangements Has. The clamping jaws 46, 46 have the objects 12

309831/0603

contacting head made of a suitable material, and the three pairs of Klemrabaokenpairs shown at the same time against three objects on the conveyor. Un a resilient pressure against the articles to ensure the jaws act vat 46 springs a "while the jaws 46 * a rigid abutment against the auegetföte by the jaws 46 on the objects' form compliant pressure. In all other points, the straightening units 49, 45 * of the construction described in US Pat. No. 3,922,134 are similar, that is, each of the units has a vertical shaft 47 (Fig. 9), which at its lower end via a bevel gear with a transmission ratio of 5: 3 is connected to one end of a transverse shaft, which in turn is drivingly connected to the main shaft 25 through a gear 50. Associated with the vertical shaft 47 is a mechanism as described in more detail in US Pat. No. 3,522,134, among others the carriage 51, which carries the respective set of three clamping jaws, _r to provide a translational and rotational movement so that the clamping jaws arrive at each rotation cycle of the shaft 47 for bearing on three articles 12 with a progressively changing rotational speed, while at remain in contact with the objects, move in the direction of the movement path of the objects at exactly the same speed as these, and sch can easily detach itself from the objects after a predetermined period of time and move away from them at a progressively changing rotational speed until they can return to their normal rotational speed.

As previously mentioned, the label reading can be provided with a labeling unit to apply only one label to each item, or it can be provided with two labeling units 55,56 (Fig. 1), where the simultaneous application of two labels on each Gegeritand is made possible. The labeling units 55, 56 are similar to one another and have intermittently moving, multi-stage rotary heads 57 and 58, each of which has a labeling device 59 with an articulated vacuum label application member 16 in each of its stages. The two rotating heads 57, 58 rotate in opposite directions

reverse direction, as indicated by the arrows in Fig. 1, and si 'are adjustable relative to each other so that they can be adapted to objects of various OrOBe _o β hold During the batch ** rotational movements of each rotating head, the on brlngglieder 16 sequentially on a label -Gripping station 60, name the labels 61 successively fed to this station and guide them to the labeling station 17, where they are then attached to the objects.

The dispensers 20 for the adhesive labels 61 to the gripping stations 60 can be commercially available devices, such as those available in the USA from Avery Products Corporation. Coropac Corporation and Dennlson Mfg. Co. are manufactured. The versatility of the machine according to the invention is evidenced by the fact that "Bie ^ öi, simply these issuers, which adhesive labels, which are completely or only partially from their carrier strelfen on which they are held, _{P are} removed and from the issuers in a vonWinkellagen plurality - * including the vertical and horizontal -.. are submitted, can be adapted As shown in Figures 1 to show k, there is such Etikettenausgeber from a "housing 65, in which the necessary for its operation mechanism is accommodated, the housing 65. carries a driven roller 66 on the outside to pull the support strelfen 67, on which the adhesive labels are held, from a supply roll 68, pull a label stripping plate 69 and a roller 70, including the support strip 67 over the plate 69 and feed it to a take-up roller 71. According to the invention, the housing 65 is provided with a support arm 72 which is mounted on an upright column 73 which is mounted on the table top 74 let, adjustable attached. The support arm 72 has a fixed cross bar 75 * on which the supply roll 68 is rotatably held.

In operation ( FIGS. 1 to k) the support strip 67 with the labels 61 adhering to it is removed from the supply roll and pulled around the sharp edge formed at the lower end of the removal plate 69. As the Tr *, strip 67 continues to bend back over the sharp edge on the stripping plate 69, the labels 61 are successively detached or peeled off from the carrying tire.

scrolls. As FIG. 3 shows, each label 61, when qs begins to detach itself from the carrier strip 67 at the lower end of the stripping plate 69, is vertically downwards over the steeply standing one. Outer surface 78 of a suction support plate 79 promoted. Shortly after the label is completely free of carrier strips, the leading end of the label strikes stops 80 which are attached to the support plate 79 in order to align the label precisely with the latter, its center line exactly with the center line of the attachment file 16 in the gripping position covers _f as will be described later. The conveying speed of the carrier tire is so high that the detached label is propelled forward over the surface 78 so that it is certain to come to rest against the stops 80 regardless of the influence exerted by the support plate 79 by the suction. As soon as the stops 80 interrupt the forward movement of the label, the suction acting from the plate 79 captures the label and holds it in an aligned position. It has been found that the alignment of the label becomes easier if the plate 78 is covered with a layer 81 of a lubricant, for example "Teflon", since such a layer prevents the friction counteracting the movement of the labels towards the stops 80. and air resistance is reduced.

The suction support plate 79 forms a wall of a label holder 82 hanging from the bottom of the housing 69. The labels » holder 82 has a closed · chamber 83, which is connected to the interior of the housing 65 via an opening provided in the bottom thereof Connection. A suitable blower (not shown) is housed in housing 69, which creates a vacuum in it, the on the parts of the support plate 79 to be covered by the label 61 through the openings 84 provided therein (FIG. 4). The vacuum generated in this way is just sufficient to hold the label in its aligned position on the surface 78 until it is inevitably removed therefrom will.

A comparison of FIGS. 2 to 4 shows that the support plate 79 and consequently the label holder 82 have a recess

- 9 -309831/0503

85 through which the attachment members 16 pass in their step-by-step movements. During each idle time of the rotary head 97, one of the attachment members 16 is in a waiting position within the recess 85, the forward surface 86 bearing the label being flush with the label support surface 7Θ of the label holder 82, so that the forward surface 86 is in contact with the middle part of the printed side of the label 7 61, which is aligned with the outer surface 78. The timing of the machine is such that the attachment member 16 then reaches this position after a label 61 projects from the support strip 67 to the supporting outer surface 78 of the label holder 82.

From Fig. 3 it can be seen _f that the shafts of the two support strip rollers 66 and 70 of the label dispenser 20 are provided with chain wheels 87 and 88, between which a chain 89 rotates. An electric clutch-brake element 90 is connected to the chain wheel 87 and controls the rotary movement of the rollers 66, 70 and thus the feed speed of the carrier strip 67. The clutch-brake-cover 90 is connected to a photoelectric sensor 91 (Fig. 2) and is actuated by this in order to initiate the advance of the carrier strip. The sensor 91 lat with respect to the conveyor 11 is arranged at a position located upstream of the labeling station 17, and specifically at a distance therefrom which is at least equal to three times the division of the objects 12. Whenever an object 12 interrupts the light beam emanating from the sensor 91, the advance of the carrier strip 67 is initiated. As a result of this arrangement of the sensor 91, the advance of the carrier strip will begin when there is an object to be provided with the first label on the carrier strip on the conveyor and just after an attachment member has moved over the label holder 82. The advance of the carrier strip is also controlled by a further photoelectric unit 92 which is arranged within the housing 65 and is also electrically connected to the clutch / brake element 90. . ■ <.Q

309831/0503

- ίο -

The light-electrical unit 92 is related in a known manner on the support strelfen 67 upstream of the first label so that it supplies an electrical signal to the clutch brake member 90 when the trailing edge of a following label 61 passes the light beam, whereby the Feed of the carrier strip is interrupted. When that happens, the first or leading label is on the Carrying strip in an aligned, protruding position on label holder 82 and its movement is interrupted. if an attachment member 16 is moved towards the position it will assume during the next idle period of the machine, a label 61 will thus be present on the label holder 82 in an aligned, stationary position.

From Fig. 4 it can be seen that in a period of rest of the Maaohine the center lines of the attachment member 16, the recess 85. the support strip 67 on the stripper plate 69 and the label 61 aligned by the stops 80 all essentially coincide. If a vacuum is then applied to the attachment member 16 and this member proceeds in the next step of its movement, the label 61 is fixed by this arrangement that is, the center lines of the label and the this supporting surface of the attachment member coincide, worn. For the example shown, if the center lines are defined as the the means for effecting the desired alignment have been described, so it is clear that there is some given line on the parts. can be chosen as a means of achieving this alignment. It is known in the relevant art that, in accordance with the manufacture of self-adhesive labels on carrier strips, these labels are applied to the strips in this way can that they are all in a precisely aligned position to each other on the carrier strip. In this respect, any given length line can be used on the usual, with adhesive labels provided support strips are taken as a reference line. The carrier strip 67 is then advanced under precise control by guides such as, for example, the guides 64 in Figs

309831/0503

for this selected predetermined line, in the example the center line, lies in alignment with the corresponding predetermined line at the stops 80. The stops 80 eliminate any inaccuracies that can occur during operation of the dispenser, for example, during the withdrawal and advancement. It is clear that the label 61, as it moves over the surface 78 of the suction support plate 79 to which these stops are attached, is retained by the friction and air resistance it is exposed to on the surface. The peeling rate of the label from its carrying elf is related to these resistances in such a way that the label progressively reaching surface 78 slides over this surface under positive or positive control of the vacuum until it comes into contact with the stops, with slides at a speed just sufficient to achieve precise alignment with the stops without warping - which the vacuum also counteracts - does .

The same result can be achieved with a label alignment device according to the invention regardless of the manner in which the Adhesive labels are supplied in a manner known per se, can be achieved. The Flg. 9 shows a label dispenser 20 which n is equipped with a known device 93 in the form of a photocell, which is so constructed and opposite the support strip 67 is arranged to align the strip and stop when the leading label 61 is within a small portion of the Support strip 67 is peeled off. The portion adhered to this is just sufficient to ensure alignment of the label, and the device will perform such alignment of the leading label with respect to the center line of the attachment member 16 with such an accuracy that it unnecessarily let on the suction support plate 79 the alignment stops 80 according to the Execution of Flg.3. and 4 to be attached,

It is clear that, while the detached part of the label is advanced, this upper surface 78 of the plate 79 below the Influence of the suction acting on this surface will slide, and

- 12 -

309831/0503

that when the feed of the Tragstrelfens has been arrested by the alignment device 93, detecting through the openings 84 acting in the suction plate 79 the label and this holds in a properly aligned position _f so that it can be absorbed by the attaching member sixteenth The suction necessary for this purpose can be on the order of 0.03 to 0.06 at. If suction is subsequently provided in the attachment member 16 for this purpose, it must be sufficiently high to effect a stronger grip on the label than the adhesive connection between the carrier strip and the remaining small portion of the label adhering to it. For example, a suction of about 0.5 at can be provided in the attachment member 16. In this way, when the attachment member 16 proceeds in the next step of movement, it is able to peel the remaining adhesive portion of the label from the carrier strip without changing the aligned position of the label on the attachment member. This embodiment according to the invention is particularly advantageous when the labels to be applied to the objects are not sufficiently rigid and tend to fold rather than slide over the support surface, as is the case when the labels are made of adhesive and printed thin plastic »layers or • films or foils.

6 and 7 show a label dispenser 20 which carries the " strip horizontally with vertically lying labels on one side of the label holder 82, the one in this embodiment Suction connection with the interior of the housing 65 through an in the wall of which has the intended opening. As in the embodiment according to FIG. 5, the label aligning device 93 is one here electrical photosellar arrangement to control the advance of the carrier strip so that it is stopped while a small one Section of the leading label adheres to the label to achieve correct alignment of the label on the label holder 82. Hence, this embodiment works in the same way In the manner as described for the embodiment of FIG. 5, when the attachment member 16 advances to the aligned label 61 VOB holder 82 and move it completely from the support strip 67 to replace. However, it is clear that the embodiment according to

309831/0503

Fig. 5 is better suited for such labels, the inherent rigidity of which is insufficient, so that they in Figs cannot be properly requested further.

The labeling unit 55 shown in more detail in FIGS. 2, 3 and 2 to 11 corresponds to the units? *, 56 according to FIG. 1. There these units are of the same structure, the description of a unit 55 is sufficient to understand the structure and the How these units work.

As shown in Fig. 3, the rotary head 57 (Fig. 1) includes a vertical shaft 95 which is supported by a suitable bearing 96 on the Table top 74 is attached, extends from which it is trimmed. Below the table top 74, a cam disk 97 with cam rollers 98 is attached to the vertical shaft 95, which in a cam track of a cylindrical cam body 99 in a known manner intervention. The cam 99 is on a horizontal shaft fastened in bearings 101 which are provided at the lower ends of the support brackets hanging down from the table top 74, rotatable recorded 1st. Aa one end of the shaft 100 is attached a sprocket 102, from which a chain becomes a sprocket leads, which is attached to the main shaft 25 1st (see. Flg. 9, the drive connections for both labeling units 55, 56 shows).

Above the table top 74, a turret plate 105 is attached to the vertical and x He 95 at a distance therefrom, which is in a suitable position Distance to each other six vertically arranged carriers having the vertical waves 107 of six labels on ~ bringing devices 59 in each of the labeling units 55, 56 wear. At the lower end of each of the vertical shafts 107 is a cam arm 108 attached to a cam roller 109 which is in a Cam track 110 in the surface of a horizontal cam plate 111, which is attached to the top of the table top 74, engages. The cam track 110 is designed so that each label removal device 59 is on its way from the label gripping station to labeling station 17 and back to station 60 progressively so '

- 14 -

309831/0503

is rotated so that the center line of the forward, the label-bearing face 86 of the respective attachment member of the ausgerichtetenEtiketta is 16 at the station 60 to coincide with the center line on the label holder 82 and eratation on the label! 17 vertical in a with the center line of the ^r sgenstandes 12 , is located radially to the vertical shaft 95 of the rotary head 57,58 directed plane.

Each label applicator 59 consists of a substantially borrowed cylindrical body 112 which is slidably supported on the vertical shaft 107 and is provided with an annular cam track 113 in which a cam roller 114 which is attached to the inner end of a pivoted lever 115, runs _o At the outer end of the lever 115, which is pivotable about the axis of a pin 117 * which is held on a support arm 116 attached to the upper end of the vertical shaft 107, the label attachment member 16 is attached. Clearly, when the body 112 slides vertically on the shaft 107, the lever 115 is forced by the cam track 113 and cam roller 114 to sway about the axis of the pin 117, thereby moving the attachment member 16 back and forth like that the dashed and solid lines in FIG. 3 are shown. The cylindrical body 112 is normally pressed into its uppermost position, in which the attachment member 16 assumes its fully advanced position, _for which purpose a vertically arranged compression spring 118 is provided, the ends of which are attached to a pin 119 on the body 112 and a pin 120 to a Collar 121 is attached to the vertical shaft 95 _o

The range of motion of the attachment member 16 from the fully retracted to the fully advanced position is regulated by a cam control. This contains a vertical leg 122, which is attached to the top of the cylindrical body 112 and at its lower end carries a cam roller 123, which against the bottom Curved path 124 of an annular cam body 125 rests, which is carried concentrically to the rotary head plate 105 by lugs 126 will. These lugs 126 are adjustably held on rods 127 which are fastened on the cam disk 111. It is to be noted

- 15 -309831/0503

ken that each vertical leg 122 in a guide lens 128 is displaceable, which is excellently attached to the rotary head plate 105. While the cylindrical body 112 thus freely the vertical shaft 107 can slide, it is held against a rotational movement by the leg 122 and the Pilhrungsblock 128 «

When the machine is in operation, the cylindrical cam 99 continuously rotated by the main shaft 25 via the chain wheels 102, 103 and via the horizontal shaft 100, and the rotary head plate 105 is advanced by one step through the cam 99 with each working cycle. If during a rest period in the Step-by-step movement of the rotary head, a label is attached "; -. device 59 at a gripping station 60 (Figs. 1 and 2), so its cam roller 123 lies on the annular cam 125 'to vertically adjust the forward, label-bearing surface 86 of the attachment member 16. The cam roller 109 lies on the cam 111 to the label carrying surface 86 parallel with the printed side of the label 61, which through the label holder 82 is held in an aligned position. In this state of the parts, the center line falls the surface 86 carrying the label coincides with the center line of the label 61, since a slight suction on the label holder 82 is held. Before the next step of movement of the attachment member 16, a suction effect is greater than it is applied to the label on the holder 82, at the attachment.

Song 16 is generated so that the label is fixed in its auece i £ p - ^; rlcntexen

IXt. At the next step, the attachment member 16 grazes

this the label from the holder 82 decreases, and the cam begins to progressively rotate the vertical shafts 107 to adjust the angle of the label held with respect to a to the axis 95 ά the vertical shaft of the rotary head directed level change radially. In addition, the annular cam body 129 begins to change the position of the cylindrical body 112 of the label application device on the shaft 107 in order to pivot the attachment member 16 about the pin 117.

At the end of this first movement step from the gripping station 60 gone are the label and the attachment member shown in FIG

309831/0503 -

Have taken 61 ^c or "16 ¹ positions designated ₀ This process continues, so that at the end of the next step of the rotating head the label and the attaching member in Figo 2 with 61"% ind 16 "Final Langen designated taken will have. It should be noted that at this time the label has been rotated so that it is almost parallel to the line of movement of the objects 12 on the conveyor 11.

During the next step of the rotary head, when the attachment member reaches the location indicated by the vertical plane 130 which contains its center line and is radial to the axis of the vertical wall 107 _r , the attachment member 16 is pivoted so far that its label-bearing surface 86 is advanced almost to the point at which the attachment member will apply the label to the item 12 ^{ for which it is intended, as indicated by the dashed lines in FIG. It is clear that by this time the item 12 * will have advanced from its position indicated in full lines to one in which its center line is also in the vertical plane 130 and the label being carried is parallel to the path of movement of this item. The surface 86 of the attachment member 16 maintains this parallel position until it almost reaches the point in which the vertical plane 132 passes through its center line and the axis of the shaft 107. For <3 ½ times, the surface 86 of the attachment member 16 will be parallel to the object 12- 'on the conveyor 11 for a moment and move at the same speed as the conveyor 11 Moved parallel to the item 1 ** 'and at the same speed as this, the annular cam 125 brings the attachment member 16 to a brief deflection forwards in order to attach the label to the item 12 * and to retreat. The label printing process takes place at the point indicated by the vertical plane I31.

Eb let to note that at this moment the center lines of the object 12 ^f , of the label to be attached or attached

3098 31/0503

and the surface 86 carrying the label lie in the plane 131 and that this is radial to both the shaft 107 of the label attaching device 59 and to the vertical full 95 of the rotary head. During the final deflection *** of the attachment link 16 the vacuum created on this is interrupted and it becomes through this positive air passed in order to affix the label to the object with certainty. On the way back to the label applicator, the mode of operation of which has been described above is, the attachment member 16 is withdrawn to the gripping station and rotated until it has returned to the state in which it is ready to close through the recess 85 in the label holder 82 go and grab an aligned label as shown in Figure 2.

The device for controlling the air-side state of the attachment member 16 is shown in FIGS. 1 to 3 and 10 and 11 Like the Flg. 3 is a part of this device attached to the upper end of the vertical turret shaft 95. This Part includes a rotatable valve plate 135 which is fixed to the shaft 95 and has six valve openings 136 (Fig. 11) with which each ei.i end of six flexible hoses 137 are connected is, the other end of which is connected in a suitable manner to one attachment member 16 each. On the rotatable valve plate 135 A stationary valve plate 136 is attached, with both plates are separated from one another by a ring 139 made of any sliding or shearing material such as "Rulon" or "Teflon" The stationary valve plate 138 has an aittige, lined with Lagerwerket off opening, in which the upper end of the rotary head » shaft 95 is excluded, and it is one with three openings Grelf opening 140, a support opening 141, and a blow-off opening 142 * ■ provided.

The three openings are arranged on the valve plate 138 so that the gripping opening 140 at the gripping station 60, the blow-off opening 142 on the labeling station 17 and the carrying opening 141 between the openings 140, 142 on the way in which the labels of carried by the attachment members. The openings 140, 142 extend completely through the valve plate 138,

while the opening 141 with an elongated space 143 in communication stands, which has a perforated bottom wall 144, so that on the attachment members 16 on their way from the gripping station 60 to the labeling station 17 is constantly a suction. The openings 140, 141, 142 fltehen with three channels 145, 146, 147 (Fig. 10) in connection, which pull through a stationary cross member 148 (Fig. 2), at one end dLe stationary valve plate 138 is attached and the other end is held on the machine frame. Thus, the cross member 148 and the valve plate form 138 a bearing for the upper end of the rotary head shaft 95.

As FIG. 10 shows, there is a Kagn tventil 149 in the channel 145, that controls the vacuum at the gripping opening 140. The channel 145 is connected together with the channel 146 to a second solenoid valve vacuum solenoid valve 150 -, to a filter 151 and a vacuum pump 152. The channel 147 is connected to the vacuum solenoid valve 150 and with an air solenoid valve 153, which the air supply from a compressed air source to the duct 147 controls. A control valve 154 is located in the supply line from the compressed air source.

From the foregoing it will be seen that when a label applicator 59 is located on the gripping station 60 during a period of rest of the rotary head, the solenoid valve 149 is forced to apply a vacuum to the attachment member 16 of the device 59 through the opening 140 in the valve plate 138 to create the opening 136 associated with the attachment member in the valve plate 135 and through the associated tube 137, whereby a label aligned with the label holder Θ2 is received. When the finger-like attachment member advances by the next two steps of the rotary head, a vacuum is applied to it from the X _r ag opening 141. During the tent space in which the attachment member 16 moves with the conveyor at constant speed, the associated one moves Valve opening in the stationary valve plate 138 under the blow-off device 142 in the plate 138, the effect of the vacuum being terminated and the compressed air being supplied to blow off the label carried by the attachment member. This blasting process is controlled by the air solenoid valve 153

From Fig. 3 it can be seen that the finger-like attachment member 16 has a configuration "to attach the label to the inclined shoulder of the bottle shown in dashed lines. By changing the shape of the attachment member 16 and the cam members controlling its movement, the attachment member can be adapted to be capable of attaching a label to any surface of the bottle, whether that surface is vertical, horizontal or inclined at any intermediate angle . Thus, FIG. 8 shows an attachment member 16 'with a straight design, with which it is possible to attach the label aligned thereon to a vertical wall of a bottle. In this embodiment, the attachment member is not, as FIG. pivoted, but it is attached to a slider 155, the associated guide block 156 of which is held on the support arm 116 "which carries the pivot pin 117 for the lever 115 _{o In} contrast to the embodiment according to FIG. 3, the lever 115 with which the attachment member 16 ' bearing slide 155 connected by a universal coupling 157. In all other respects, the design of the label application device of FIG. 3 is similar to that of FIG. 3.

In his work, the attaching member 16 is displaced 'back and sliding, d "h _o, it does not lead, as the attaching member 16, a pivoting movement. In all other respects, however, the link 16 * operates like the link 16. Accordingly, during its final advancement step, the application link 16 * makes a short, forward displacement stroke at the labeling station in order to apply the label to the item 12 (FIG. 6). The same result can be obtained if the upper part of the attachment member 16 is bent backwards - and the pivoting configuration according to FIG. 3 is used.

The labeled objects 12 go from the labeling station 17 to the pressing station 18, in which the labels are finally applied by suitable means, Z ₀ B ₀ the pressing means according to US Pat. No. 3,522,134

be attached; However, a pressing device can also be used for the final fastening, as shown in FIG Fig. 1 is shown.

In this embodiment, the labeled objects run in the pressing station 18 between the inner truas of two pressure belts 160 and 161, which are made of compressible material, such as thick foam or sponge rubber, and are able to cover the entire surface of a label attached to the object applying resilient pressure through ₀ The pressure belts 160, 161 are driven by rollers mounted on the belt shafts 162, 163 so that the belts 160, 161 move in the same direction and at the same speed as the articles 12 on the conveyor As FIG. 9 shows, the belt shafts 162, 163 are connected via vertical shafts 164, 165 and horizontal shafts 166, 167 to the transverse shaft 49, which is driven by the main shaft 25. This ends on the discharge side for the objects in a gear box 170 / in which a connection to a transverse shaft with a chain wheel 171 attached to it is formed. A chain rotates between the chain wheel 171 and a chain wheel 172 which is fastened to a transverse shaft which carries a drive roller 173 for the conveyor which is aligned with the shaft 25. The other roller 174 (Fig. 1) for the conveyor runs freely and near the gear box 170, the main drive shaft 22 is provided with a sprocket 175 which is connected by a chain to a sprocket 176 attached to the drive shaft of a gear box 177. The drive wheel 178 (FIG. 1) for the upper printing belt 19 is connected to the gear box 177. In the foregoing embodiments, a label holder 82 is used to slidably receive a label 61 from the label dispenser, with the attachment member 16 applying the aligned labels to the label holder for delivery to the labeling station. However, it is within the scope of the invention to align the labels directly on the attachment members without having to use a vacuum label holder 82 for this purpose

use. Referring to Figure 12, a label dispenser 20 of the type shown in Figures 6 and 7 is shown with the label 61 properly oriented while it is partially suspended or attached to the strap 67. The label aligned in this way, instead of sliding it over the vacuum plate of the holder as in the embodiment according to FIG. 6, is guided over the label support surface 181 of the attachment member 180, which has come to rest shortly before the label is fed to it. The practice is followed in that a suction of about 0.07 is applied to the Anbringgliedern 180 just before the supply of labels to these at the gripping station generates at to allow the label to slide on the label supporting surface 181 in an aligned LageTrUhrt and still allow the aligned labels to adhere to the attachment members. The vacuum system can be timed so that suction is generated when an attachment member approaches its receiving position, in which the label support surface 181 substantially coincides with the trajectory of the detached portion of the label which is then partially peeled off or peeled off the support elf 67.

Fig. 19 shows the manner in which labels, the vea have been completely detached from the carrier strip 67 by the wiping action of the dispenser 20 on the label carrier surface 184 an attachment member 185 can be aligned. It's clear, that the dispenser 20 according to FIG. 19 differs from that in FIGS type shown and the labels in the manner explained for this AusfUhrungeformn releases.

In the embodiment according to FIG. 19, the attachment members 185 come successively in their label receiving position in the Oreifstatlon to a stop and received before the supply of a label to them a suction of little size. The attachment links 189 can each be provided with old alignment stops 186 which on its forward suction surface, which is the label support surface 184 forms, and are attached under this. The attacks 186

work in aer to the stops ΘΟ (Fig. 3 and 4) explained manner to effect the correct alignment of the advanced label 61 on the attachment member. The stops need not be attached to the attachment members, but rather a set of stops 186 *, shown in dashed lines in FIG. 15, Bind ρ, can be provided at the gripping station that the attachment links in between in the in the Flg. 2 and 3 go through, and they can be held at this distance by supports 187 attached to the label dispenser 20 »

In operation, in this embodiment, the label 61 ^s vcia encoder is driven forward after the attachment member ar * of the gripping station has come to a stop in a position, In

it receives the label to slide on its support surface TS4 on which a suction produced iat _o The label 61 · output comes astride the stops 186 to rest "align it to the label supporting surface 184 of the Anbringgliades exactly. During the next step of movement of the attachment member, its suction surface removes the label from the stops and brings it to the labeling station.

Slide Flg. 13 and 14 show an embodiment with which it is ensured that each label is provided with an identification or poet number, even if, for example, a label should be missing on the carrier strip led to the dispenser. As previously described, the photoelectric glans 92 in the housing 65 interrupts the movement of the carrier strip 67 when the trailing edge of a label 61 passes through the unit and triggers or switches it. During this idle period, a printing unit 191 prints unfamiliar identification or postal information ^{on a subsequent label 61 f dl.} Let it be assumed that, as shown in FIGS. 13 and 14, the photoelectric unit 92 has just been switched by a label 61 "in order to interrupt the advance of the carrier strip, and the space 190 on the strip, the Usually it should be provided with a label, let it be empty. At the next

The photoelectric sensor allows movement of the support strip due to the fact that in area 190 there is no label is, a further movement of the carrier tire until the trailing The edge of the next attached label 61 "triggers the unit 92.

Such uninterrupted advancement of the backing strip over two holding parts would have the consequence 'that the label 61' The following label 61 "does not have an identification or item name would be provided. If such a label is attached to an object, there is no possibility of such a label To locate the object if its content is in any way questionable.

According to the invention, this possibility is eliminated in that a second such unit 194 is coupled to the light-electric sensing unit 92, which also stops the carrier strip when the trailing edge of a label 61 ' ^} ' passes through 3io after the usual single stopping step of the carrier strip · Dm · Printing unit 191 then works to print on the label 61 '·· via the item number. It is clear that the printing mechanism 191 *, which is of a known type, is connected, as usual, to the main shaft 25 in a suitable manner, so that every time the carrier can rest it is actuated to print.

The manner in which the aforementioned control occurs can be understood from Fig. 14, which shows an electrical control box 195 for which the light-electrical sensor 91 is used for the objects and the Lichteleketrisohen feelers 92, 194 for the labels are electrically connected. With the la box 199 Included switching elements are also the printing unit 191, the electrical clutch I96 and brake 197, the latter together form the clutch Brema element 90 from Flg. 3 »electrically connected ; «Q.
