Definitions
- This invention relates to a labelling apparatus.
- British Patent Specification No. 1563892 describes a labelling apparatus which separates a label from a longitudinally split carrier and then transfers the label to an article to be labelled by means which moves in a generally linear, reciprocal manner between a position in which a label is picked up and a position in which the label is applied to the article. These movements must be timed to coincide with the separation of a label from its carrier and with the presentation of an article to the labelling apparatus.
- the assembly which has been constructed to effect these movements is quite complicated and it requires careful engineering to relatively precise tolerance if reliable operation is to be obtained.
- the mechanism comprises a number of parts which perform a reciprocating movement for the purposes of label advance and transfer.
- Reciprocating systems cannot reliably be operated at very high speeds (above 250 to 300 feet/minute).
- Thus such mechanism places a constrain upon the speed at which articles can be labelled by the apparatus.
- the present invention has been made from a consideration of the above-mentioned problems.
- the aforesaid assembly of GB-A-1563892 is necessarily located on the side of the apparatus which limits the minimum width thereof. This in turn limits the minimum distance between adjacent labelling apparatus in a multiple labelling device having a plurality of labelling apparatus side by side for simultaneous labelling of items such as fruit being advanced in parallel streams.
- the normal distance between the centres of such streams is of the order of 130 mm which is far narrower than the minimum distance that can be obtained with the existing labelling machines arranged in side by side relationship.
- the labels for the labelling apparatus are, as stated provided on a longitudinally split carrier.
- the carrier is preferably wound on a bobbin from which it can be unreeled and advanced through the labelling apparatus. However, when the bobbin is emptied it can take several minutes to install a fresh bobbin and thread the carrier through the labelling apparatus. Similarly if the carrier should break or other problems develop with the labels and/or carrier the apparatus must be stopped while the broken carrier is re-threaded or other appropriate remedial action taken. During the time that the apparatus is inoperative for the above reasons, a large number of articles can pass the labelling apparatus without being labelled.
- a high speed labelling apparatus for sequentially separating labels from a carrier strip and applying the labels to fruit, said apparatus comprising a label applying means, means for moving the label applying means between a label receiving position and a label applying position, rotating the label applying means in one direction continuously, means for separating a label from the carrier strip, means for mutually bringing the label applying means into contact with a label and means for advancing the carrier strip and the label applying means synchronously so that said label is separated from the carrier strip by the separating means in a direction substantially the same as the direction of movement of the label applying means into the label receiving position, means adapted to expand the label applying means at said label applying position for depositing a label on a fruit object and thereafter to retract the label applying means, wherein the means for mutually bringing the label applying means into contact with a label comprises means for advancing the carrier strip over the separating means to achieve a speed equalling the circumferential speed of the label applying means prior to moving the separating means from a first position remote from the label applying means
- the labelling apparatus comprises labels supplied from a carrier strip including first and second longitudinally arranged carrier strip portions and a plurality of labels removably adhered therealong so as to bridge the carrier strip portions, wherein the means for separating the label from the carrier strip comprises a plate having first and second substantially planar surfaces and a plate edge including first and second non-aligned edge portions, transport means for moving said carrier strip across one of the planar surfaces, over the edge portions whereat the carrier is separated, and for moving the separated portions over further edge portions and along different paths across the other of the planar surfaces.
- the label applying means preferably includes a plurality of label handling means arranged at regular angular intervals therearound. With such an arrangement a label can be received from the label strip at the same time as a label received somewhat earlier, is applied to an item to be labelled. It will be appreciated that such an arrangement permits labelling at very much higher speeds than with previously known devices.
- the label applying means can include label handling means arranged at intervals axially along the applying means, there being an associated label supply arrangement for each axial interval where label handling means is located.
- Sensing means is preferably provided for noting the presence or absence of an item to be labelled.
- the sensing means can be used to control the supply of labels to the label applying means.
- the label strip is preferably wound on a bobbin which is receivable in a housing, said housing also including the plate and the transport means and being adapted for removal from the labelling apparatus.
- the label strip can be supplied in other kinds of format for example fan-folded.
- the labelling apparatus comprises a cassette 12 having a spindle 14 on which a bobbin or reel 16 of label strip 18 is rotatably mountable.
- the label strip is of the kind which comprises a carrier strip 20 having labels 22 at regular intervals therealong.
- the outer face of each label 22 carries the appropriate information which may be printed thereon and the face adjacent the carrier is coated with contact adhesive.
- the carrier strip is adapted to be separated longitudinally along the centre line 24 which may be split for that purpose.
- the labels extend across the centre line 24. Examples of suitable label strips are described in British Patent Specification No.1563892.
- the separation of the labels from the carrier strip is effected by substantially the same principles as disclosed in the above-mentioned British Patent Specification No.1563892.
- the label strip is advanced by transport means 30 which will be described in detail later, across the underside of a separator plate 32 to a V-shaped notch 34 which defines edges 36 and 38.
- the separation line 24 is aligned with the apex of the notch 34 whereat the carrier is separated into two parts 20a and 20b.
- the carrier parts are led over the edges 36 and 38 respectively, laterally across the top of the plate 32 over outer edges 40 and 42 and then back along the underside of the plate parallel, but in the opposite direction, to the label strip 18.
- Label strip 18 from the reel 16 is led around tension roller 50 and then around tape friction drum 52.

- Each of said carrier parts is led around a separate guide roller 55 and then to the appropriate haul-off roller 56 or 58.
- the rollers 56 and 58 are provided with small projecting teeth or pins 60 which make positive engagement with the carrier parts.
- Each haul-off roller 56 and 58 is provided with a pair of spring biassed pressure rollers 62, 64 which urge each carrier part into contact with the haul-off roller over which it is led.
- the carrier parts finally drop under gravity into a waste receiver 66.
- Other arrangements can be made for disposal of the waste carrier parts.
- the carrier waste can be drawn away through a vacuum tube and chopped by suitable means such as a rotary cutter.
- Tension in the label strip is maintained by a pressure plate 70 which bears upon the strip as it passes along the underside of the separator plate.

- the cassette can be removed and replaced with a fresh cassette with a full reel 16 already threaded up. This change can be effected very quickly without stopping the apparatus. At worst only a few articles will pass during the cassette change without being labelled.
- bellows are provided for carrying labels from the separator plate to the objects to be labelled
- other provision can be made which will produce the same result.
- bellows cylinders preferably of lightweight material such as plastics can be provided which reciprocate in appropriate bushings in the label applying means 120 in response to vacuum and pressure as with the bellows. In other words the cylinders are retracted by means of the vacuum except at the label applying position where they are moved outwardly from the label applying means to deposit a label on an object.
Description
- This invention relates to a labelling apparatus.
- British Patent Specification No. 1563892 describes a labelling apparatus which separates a label from a longitudinally split carrier and then transfers the label to an article to be labelled by means which moves in a generally linear, reciprocal manner between a position in which a label is picked up and a position in which the label is applied to the article. These movements must be timed to coincide with the separation of a label from its carrier and with the presentation of an article to the labelling apparatus. The assembly which has been constructed to effect these movements is quite complicated and it requires careful engineering to relatively precise tolerance if reliable operation is to be obtained.
- In addition the mechanism comprises a number of parts which perform a reciprocating movement for the purposes of label advance and transfer. Reciprocating systems cannot reliably be operated at very high speeds (above 250 to 300 feet/minute). Thus such mechanism places a constrain upon the speed at which articles can be labelled by the apparatus.
- The present invention has been made from a consideration of the above-mentioned problems.
- The aforesaid assembly of GB-A-1563892 is necessarily located on the side of the apparatus which limits the minimum width thereof. This in turn limits the minimum distance between adjacent labelling apparatus in a multiple labelling device having a plurality of labelling apparatus side by side for simultaneous labelling of items such as fruit being advanced in parallel streams. The normal distance between the centres of such streams is of the order of 130 mm which is far narrower than the minimum distance that can be obtained with the existing labelling machines arranged in side by side relationship.
- US-A-4253902 and EP-A-0031383 disclose arrangements in which a rotating drum carries a number of handling devices which on rotation receive labels from a carrier strip and transfer these to objects to be labelled neither of these published documents show an arrangement in which the circumferential speed of the drum carrying the labels equals the speed of the carrier strip upon transfer of the labels to the drum.
- The labels for the labelling apparatus are, as stated provided on a longitudinally split carrier. The carrier is preferably wound on a bobbin from which it can be unreeled and advanced through the labelling apparatus. However, when the bobbin is emptied it can take several minutes to install a fresh bobbin and thread the carrier through the labelling apparatus. Similarly if the carrier should break or other problems develop with the labels and/or carrier the apparatus must be stopped while the broken carrier is re-threaded or other appropriate remedial action taken. During the time that the apparatus is inoperative for the above reasons, a large number of articles can pass the labelling apparatus without being labelled.
- According to the invention there is provided a high speed labelling apparatus for sequentially separating labels from a carrier strip and applying the labels to fruit, said apparatus comprising a label applying means, means for moving the label applying means between a label receiving position and a label applying position, rotating the label applying means in one direction continuously, means for separating a label from the carrier strip, means for mutually bringing the label applying means into contact with a label and means for advancing the carrier strip and the label applying means synchronously so that said label is separated from the carrier strip by the separating means in a direction substantially the same as the direction of movement of the label applying means into the label receiving position, means adapted to expand the label applying means at said label applying position for depositing a label on a fruit object and thereafter to retract the label applying means, wherein the means for mutually bringing the label applying means into contact with a label comprises means for advancing the carrier strip over the separating means to achieve a speed equalling the circumferential speed of the label applying means prior to moving the separating means from a first position remote from the label applying means to a second position adjacent the label applying means and means to return the separating means to the first position.
- Preferably the labelling apparatus comprises labels supplied from a carrier strip including first and second longitudinally arranged carrier strip portions and a plurality of labels removably adhered therealong so as to bridge the carrier strip portions, wherein the means for separating the label from the carrier strip comprises a plate having first and second substantially planar surfaces and a plate edge including first and second non-aligned edge portions, transport means for moving said carrier strip across one of the planar surfaces, over the edge portions whereat the carrier is separated, and for moving the separated portions over further edge portions and along different paths across the other of the planar surfaces. The label applying means preferably includes a plurality of label handling means arranged at regular angular intervals therearound. With such an arrangement a label can be received from the label strip at the same time as a label received somewhat earlier, is applied to an item to be labelled. It will be appreciated that such an arrangement permits labelling at very much higher speeds than with previously known devices.
- For labelling of items being advanced in a plurality of parallel streams the label applying means can include label handling means arranged at intervals axially along the applying means, there being an associated label supply arrangement for each axial interval where label handling means is located.
- Sensing means is preferably provided for noting the presence or absence of an item to be labelled. The sensing means can be used to control the supply of labels to the label applying means.
- The label strip is preferably wound on a bobbin which is receivable in a housing, said housing also including the plate and the transport means and being adapted for removal from the labelling apparatus. The label strip can be supplied in other kinds of format for example fan-folded.
- Specific embodiments of the invention will now be described by way of example with reference to the accompanying drawings in which:-
- Fig.1
- shows diagrammatically and in side elevation the general arrangement of a labelling apparatus;
- Fig.2
- is a front elevation of a part of the apparatus of Fig.1;
- Fig.3
- is a detail of part of the label strip transport means;
- Fig.4
- is an end elevation of the transport means of Fig.3;
- Fig.5
- shows the internal structure of the label applying means; and
- Fig.6
- is an under plan view of the separator plate.
- Referring to the drawings the labelling apparatus, generally 10, comprises a
cassette 12 having a spindle 14 on which a bobbin orreel 16 oflabel strip 18 is rotatably mountable. The label strip is of the kind which comprises acarrier strip 20 havinglabels 22 at regular intervals therealong. The outer face of eachlabel 22 carries the appropriate information which may be printed thereon and the face adjacent the carrier is coated with contact adhesive. The carrier strip is adapted to be separated longitudinally along thecentre line 24 which may be split for that purpose. The labels extend across thecentre line 24. Examples of suitable label strips are described in British Patent Specification No.1563892. - The separation of the labels from the carrier strip is effected by substantially the same principles as disclosed in the above-mentioned British Patent Specification No.1563892. Thus the label strip is advanced by
transport means 30 which will be described in detail later, across the underside of aseparator plate 32 to a V-shaped notch 34 which definesedges separation line 24 is aligned with the apex of thenotch 34 whereat the carrier is separated into twoparts edges plate 32 overouter edges label strip 18. - As the label strip advances and the carrier is separated at the notch labels as indicated by the label referenced 44 are freed from the carrier.
-
Label strip 18 from thereel 16 is led aroundtension roller 50 and then aroundtape friction drum 52. Thefriction drum 52 is mounted on ashaft 54 which is rotatably mounted in thecassette 12. Haul-offrollers shaft 54, one on each side of thefriction drum 52. Atape feed gear 53 is mounted onshaft 54 between theroller 58 and thefriction drum 52. The spacing between therollers friction drum 52 preferably matches the spacing on theseparator plate 32 between thelabel strip 18 and the separatedcarrier parts separate guide roller 55 and then to the appropriate haul-offroller rollers pins 60 which make positive engagement with the carrier parts. Each haul-offroller pressure rollers waste receiver 66. Other arrangements can be made for disposal of the waste carrier parts. For example the carrier waste can be drawn away through a vacuum tube and chopped by suitable means such as a rotary cutter. - Tension in the label strip is maintained by a
pressure plate 70 which bears upon the strip as it passes along the underside of the separator plate. A pair of bolts 72 (only one of which is visible in Fig.5) extend through theplate 32 and are engaged in theplate 70. The spacing betweenbolts 72 is sufficient to permit the label strip to pass therebetween. Acompression spring 74 surrounds eachbolt 72 between theplate 32 and the head of the bolt so that the bolts are urged upwardly and hence theplate 70 is urged towards the underside ofplate 32. - The
plate 32 is pivotally mounted at theend 80 thereof adjacent thetape friction drum 52. Acrank 82 pivotally mounted at 84 belowplate 32 has onearm 85 provided with aroller 86 which engages the underside ofplate 32. Theother arm 87 ofcrank 82 has acam follower roller 88 which engages acam 90. Aspring 91 in ahousing 93 fixed to thecassette 12 is arranged to bear on the upper surface ofplate 32 to urge it downwardly. - The
cam 90 has a profiled surface which is repeated twice around the periphery. In other words the cam is designed to produce the same sequence of movements in the cam follower for every half revolution thereof. Thecam 90 is fixed to theoutput hub 93 of solenoid actuated two stopwrap spring clutch 94. - A
pawl 101 rotatably mounted onshaft 98 has oneend 102, urged byspring 103 into engagement with atoothed collar 104 of awrap spring clutch 96 mounted ondrive shaft 106. Theother end 105 of thepawl 101 engages one or other of twolatch rollers 107 on thecam 90. A drive pulley 108 also fixed to clutch 96 is connected by anendless belt 109 to apulley 110 on drivenshaft 112. Agear 114 is also provided onshaft 112 for driving engagement with thetape feed gear 53. It will be understood that gear trains may replace the arrangements of pulleys and belts. - The
shafts conveyor 154 which carries the items to be labelled. - Label applying means 120 comprises a
body 121 having a plurality offaces 122, six in the illustrated embodiment and having aninternal bore 123 of circular cross-section lined by abush 125. A bellows 124 is fixed to each face by suitable means so as to surround a hollow projectingboss 126. Apassageway 128 extends from each boss through thebody 121 and throughbush 125. - A
tube 132 is mounted in thebush 125 so that thebody 121 andbush 125 can rotate relative thereto. Asecond tube 135 is disposed withintube 132 thereby defining anannular space 130 betweentubes Bores 134 are formed intube 132 whereby thepassageways 128 can be brought into communication withspace 130 as the body rotates. - A
passageway 136 extends from theinterior 138 of thetube 135 to the surface of thebore 123, there being no communication between theinterior space 138 and thespace 130. - The
body 121 is mounted for rotation just below theseparator plate 32 at the end thereof where labels are separated from the carrier. Rotation of the body is effected by anendless belt 140 which extends around apulley 142 on the body and apulley 144 ondrive shaft 92. An air pump (not shown) is arranged to deliver air through inlet 150 into theinterior space 138 and at the same time to evacuate fromoutlet 152 the air in thespace 130. - The free end of each bellows is provided with a valve which permits air to be drawn into the bellows but which substantially closes when the air pressure within the bellows is greater than the external pressure. The particular kind of valve employed is a matter of choice.
- As illustrated diagrammatically in Fig.1
conveyor 154 forarticles 156 to be labelled is arranged to move past the labelling apparatus below thelabel applying means 120. The conveyor is arranged to move thearticles 156 at substantially equispaced intervals. Upstream of the label applying means an optical, or other suitable,article sensing device 158 is provided which produces a signal when anarticle 156 moves therepast. The sensing device is mounted in ahead 162 and is connected to an electronic timing system which triggers operation of the solenoid operatedwrap spring clutch 94. - The labelling apparatus operates as follows:-Assume that the conveyor is advancing in the direction of
arrow 166 and the label applying means is continuously rotated. When an article is sensed by thedevice 158 the solenoid operatedwrap spring clutch 94 is energised so that theoutput hub 92 andcam 90 rotate one half revolution.Cam roller 107 liftsarm 105 which causespawl 101 to be rotated anticlockwise thus releasingend 102 fromclutch collar 104.Clutch 96 is thus engaged to drive via the tape,feed gear 53 in anticlockwise rotation through pulley 108,belt 109,pulley 110,shaft 112 andgear 114. The movement of thegear 53causes shaft 54 to rotate also and therewith the haul-offrollers Spring 103 returns pawl 101 into engagement withclutch collar 104 to prevent further advance of the label strip. - A very short time, (for example 5 milliseconds) after
cam roller 107 has movedcam arm 105 to initiate label supply, the profile oncam 90 has rotated to permit clockwise rotation of crank 82 about 84 so thatplate 32 drops downwardly under the action ofspring 91 and places label in contact with a bellows on the label applying means. It will be appreciated from the foregoing that by slightly delaying the movement of the separator plate the label presented to the label applying means will be moving at the time that it contacts a bellows. The speed of movement of the label at the moment of contact with a bellows equals the linear speed of the bellows. - These movements are also adjusted to take place so that
plate 32 is lowered when the label applying means has rotated to bring abellows 124 into position therebeneath. With a label apparatus as illustrated with six bellows around thebody 121 the aforesaid rotation of the label applying means is through 60°. At the same time a label is separated from the carrier and is, therefore, held by suction onto the free end of the bellows because of the reduced pressure therein which exists by virtue of the communication of the bellows throughpassage 128 with thespace 130. - As
successive articles 156 on the conveyor are sensed bydevice 158 the above sequence of movements is repeated. At the third cycle the article has now arrived below the label applying means and in register with the bellows that picked up a label as a result of the movements set in train by the sensing of that particular article. As can be seen in Fig. 5 thepassageway 128 in the lowermost position connects the bellows throughpassageway 136 to thespace 138. The bellows, therefore, in that position is expanded by the air pressure and the label carried by the bellows is pressed onto the article. The provision of a flexible bellows enables the labels to be applied to articles of different size and shape and to articles which may be rolling or rotating during their linear advance past the labelling apparatus. Further rotation of thebody 121 causes thepassageway 128 of the expanded bellows to be reconnected through anaperture 134 of thespace 130 so that the bellows collapses. - It will be appreciated that the position of the
sensing device 158 is chosen with regard to the number of steps that the label applying means takes between receiving a label at the separator plate and arriving at the position where the label is to be applied to an article. In addition the speed of the conveyor and the movement of the labelling apparatus must be matched. - It will be apparent from the foregoing description that if no article is sensed by the
sensing device 158 the solenoid 159 is not actuated and the cycle of operations is not initiated. Theplate 32 remains in its upper position and no label is received by the label applying means. - The embodiment just described can be constructed with an overall width of the order of 100 mm. A compact multiple labelling machine for labelling parallel streams of articles can be made by disposing a plurality of labelling apparatus in side by side relationship as illustrated in Fig.2 with a common drive means. The
bellows 124 for the plurality of labelling apparatus are preferably all disposed on a single body. - A further advantage of the embodiment just described is that the
cassette 12 together with the tape transport means 30 and theplate 32 can be adapted for removal from the labelling apparatus. Thus when thereel 16 is exhausted the cassette can be removed and replaced with a fresh cassette with afull reel 16 already threaded up. This change can be effected very quickly without stopping the apparatus. At worst only a few articles will pass during the cassette change without being labelled. - Provision may also be made for adjusting the length of tape indexed in a cycle of operation as may be necessary for different sizes of label. If a large label is to be applied the tape must be advanced in each cycle through a greater distance than for a smaller label.
- Although in the embodiment just described, bellows are provided for carrying labels from the separator plate to the objects to be labelled, other provision can be made which will produce the same result. For example instead of bellows cylinders preferably of lightweight material such as plastics can be provided which reciprocate in appropriate bushings in the label applying means 120 in response to vacuum and pressure as with the bellows. In other words the cylinders are retracted by means of the vacuum except at the label applying position where they are moved outwardly from the label applying means to deposit a label on an object.
