Definitions

  • the present invention relates to an apparatus for supplying articles of a circular cross-section in longitudinally moving transversely aligned rows for a package forming apparatus.
  • the present invention seeks to provide an improved apparatus for supplying circular cross-section articles in longitudinally moving rowt.
  • the present invention provides apparatus for supplying articles of a circular cross-section in longitudinally moving transversely aligned rows, characterised in that said apparatus includes means for arranging the articles in internested columns wherein transversely adjacent articles are longitudinally offset, and an aligning device for moving adjacent articles into transverse rows, said aligning device including guide means defining a separate path for each column of articles, said paths varying in length in accordance with the longitudinal offsetting of the transversely adjacent articles when internested.
  • the clusters which are to be wrapped are supported by both upper and lower conveyors which move in unison with the upper conveyor or having retaining elements which serve to prevent tipping of the articles in the cluster and at the same time assure a clamping of the wrap film relative to the clusters during the drawing thereof.
  • the lower conveyor includes plural sets of individually mounted support elements which fully support the articles of the clusters and are at the same time individually movable with respect to the articles so as to permit the folding of the lower closure flaps beneath the cluster.
  • simple means are provided for folding a rear closure flap beneath a cluster, the simple means being an auxiliary support which simultaneously folds the portion of a rear closure flap beneath the cluster and clamps the same against the underside of the cluster in a supporting relation for the rear portion of a cluster whereby the rear one of the support elements may be released from the cluster, after which air blast means carried by the auxiliary support may direct the rear closure flap fully beneath the closure to a position where the rear support element may return to its cluster supporting position with the rear closure flap in its fully folded position.
  • the apparatus includes a wrapped package receiving platform which serves to support the front portion of a cluster while the rear of the cluster is still supported by a rear one of the support elements and the movement of the partially wrapped cluster onto the platform serves to fold the front bottom closure flap into place and at the same time tightly draws the wrap about the cluster to provde a tight package.
  • a machine which is specifically adapted to receive articles arranged in transverse rows and separated into clusters for wrapping in a wrap film which is preferably formed of plastics material which is heat shrinkable in a shrink oven in a conventional manner.
  • the illustrated machine is specifically constructed to receive cans arranged in two transverse rows of three cans each. It is to be understood, however, that the machine is not so limited. While the machine is primarily intended to receive articles arranged in two transverse rows, the number of articles in each row may vary from one to a much greater number as may be convenient for forming a package of such articles. Further, while the articles have been illustrated as being cans, the articles could be other types of containers including boxes, bottles and jars.
  • the articles When the articles are of circular cross-sectont, such as cans or bottles, the articles will be supplied to the machine along a delivery path generally designated by the numeral 10in Figure 3, and this delivery path is of a width determined by the spacing of side guides 12 so that the articles will be arranged in columns in nested relation which is the normal relationship assumed when such articles are randomly delivered in a crowded condition.
  • the nested columns of articles are received by an aligning device which is generally identified by the numeral 14.
  • the aligning device includes an endless conveyor 16 which functions as a moving support for the articles and serves to convey the articles from right to left as viewed in Figure 3.
  • the articles pass from the aligning device 14 and are received on support strips 24, there being one support strip for each column of articles.
  • the articles proceed along the support strips 24 and are engaged by an infinitely variable spacing feeder to assure the transverse alignment of the rows of articles.
  • the feeder 26 includes flight bars 28 having thereon pairs of pins 30 which engage behind the articles and assure the movement thereof along the strips 24 in transverse alignment.
  • the transversely aligned and columnized articles pass to an infeed conveyor 32 while still supported on the support strips 24.
  • the infeed conveyor 32 includes two conveyor chains 34 which have extending transversely therebetween flight bars 36.
  • Each flight bar 36 has pairs of pins 38 projecting upwardly therefrom with pins of each pair being disposed on opposite sides of a respective one of the support strips 24 for engaging a rear portion of an article in the same manner as do the pins 30 of the flight bars 28..
  • the spacing of the flight bars 36 is . such that the articles are moved along the support strips 24 arranged in clusters C of, in the illustrated form of the invention, six articles, the articles being arranged in two transverse rows of three articles each.
  • the infeed conveyor 32 feeds the clusters C to the wrapping station of the machine, the wrapping station being generally identified by the numeral 40.
  • each cluster C is to be wrapped with a wrap film supplied from a continuous roll 42 of such film.
  • the film is delivered from the roll 42 by a feed mechanism 44 at a constant rate in accordance with the predetermined demands of the wrapping station 40.
  • the feed mechanism 44 includes a drive roll 46 and a back-up roll 48.
  • the drive roll 46 is carried by a support 50 and has a fixed axis of rotation.
  • the back-up roll 48 is carried by a pivotally mounted support 52 which is connected to the support 50 by means of a spring 54 so as constantly to urge the back-up roll 48 toward the drive roll 46 and thus form a nip assuring the positive driving and feeding of the wrap film, which film is identified by the numeral 56.
  • the film 56 passes around a pair of idler rolls 58, 60 into the wrapping station 40.
  • a cluster C to be wrapped passes under a portion of the film 56 leading into the wrapping station 40.
  • the film behind the cluster is drawn down past the cluster and between that cluster and the next following cluster until the necessary film to form the required wrap has been drawn.
  • the drawn film is then severed as shown in Figure 2b with the result that the cluster C has the wrap W now disposed over the top and down the two sides thereof and the wrap includes a front bottom closure flap 62 and a rear bottom closure flap 64.
  • the flap'64 is preferably of a length no greater than the longitudinal dimension of the article and the flap 62 is of a length approaching the longitudinal dimension of the cluster. This is clearly shown in Figure 2b.
  • the flap 64 is folded beneath the rear portion of the cluster and then the cluster is moved onto a supporting platform, generally identified by the numeral 66 which simultaneously folds the front flap 62 beneath the cluster and effects tightening of the wrap W about the cluster to form the completely wrapped cluster of Figure 2g, which wrapped cluster is then delivered to a conventional shrink tunnel (not shown) where the flaps 62, 64 are first heat bonded together and then the film is heat shrunk in a conventional manner.
  • the wrapping station 40 includes a lower conveyor generally identified by the numeral 68.
  • the lower conveyor 68 includes two transversely aligned chains 70 which carry transversely aligned support plates 72.
  • Each transversely aligned pair of support plates 72 carry a pair of pivotally mounted arms 75, 76 which, in turn, carry a front support element 78 and a rear support element 80.
  • Each arm 74 is pivotally mounted on a pivot 82 carried by. the respective support plate 72 and has connected to the .. outer end thereof the respective transversely extending front support element 78.
  • the inner end of the arm 74 is provided with a cam follower 84 which engages a first cam 86 for positioning the front support elements 78.
  • a spring 88 associated with the pivot 82 is a spring 88 which constantly urges the arm 74 in a clockwise direction about the pivot 82 to hold the cam follower 84 against the cam 86.
  • Rotation of the arm 74 in a clockwise direction is restricted by a pin 90 extending through a slot 92 in the plate 72.
  • the arm 76 is of a similar construction and mounting, but is of a different configuration.
  • Each arm 76 is pivotally mounted on a pivot 94 carried by its respective support plate, and is urged to rotate about that pivot in a clockwise direction by a spring 96 as shown in Figure 11.
  • the outer ends of pairs of the arms 76 are joined by the respective rear support elements 80 and the inner end of each arm 76 is provided with a cam follower 98 which engages a cam 100.
  • Each arm 76 also carries a pin 102 which is received in a slot 104 in the support plate 72 to limit the rotation of the arm by its spring.
  • the wrapping station 40 also includes an upper conveyor, generally identified by the numeral 106.
  • the upper conveyor 106 includes a pair of transversely spaced and aligned conveyor chains 108 which have extending therebetween sets of retainers, each set of retainers including a front retainer 110 and a rear retainer 112.
  • the front retainers 110 are preferably in the form of angle members and engage upper front corners of the clusters.
  • the rear retainers 112 have resilient pads 114 on the undersides thereof, which pads engage the upper surface of the rear portion of a cluster. The relationship of the retainer 110 and pad 114 with respect to a typical cluster is best shown in Figure 6.'
  • the wrapping station 40 also includes a draw unit generally identified by the numeral 116.
  • the draw unit 116 functions both to draw the film 56 down between adjacent clusters and to feed wrapped clusters off of the supporting platform 66.
  • the draw unit 116 also includes a pair of transversely aligned and transversely spaced conveyor chains 118 which are suitably mounted for movement in unison. Extending between the chains 118 are pairs of draw members 120 and 122.
  • the draw member 120 leads the draw member 122 and serves as the primary drawing element to draw the film between adjacent clusters.
  • the draw member 122 cooperates with the draw member 120 when the film is below the predetermined path of movement of the clusters to tension the film to facilitate cutting thereof in a manner to be described hereinafter.
  • the draw member 120 also functions to position wrapped clusters from the supporting platform in a manner also to be described hereinafter.
  • the wrapping station 40 further includes a spacing device generally identified by the numeral 124.
  • the spacing device 124 also includes a pair of transversely spaced and transversely aligned conveyor chains 126.
  • a plurality of spacing units 128 are carried by the conveyor chains 126.

  • Each support plate 132 also has mounted thereon an arm 136.
  • The'remote ends of the arms 134, 136 are pivotally joined together to form a scissors arrangement. Extending between the joined together outer ends of the arms 134, 136 is a spacer element 138.
  • the arm 134 has rigidly secured thereto a further arm 140 which carries a second spacer element 142.
  • the scissors arrangement of the arms 134, 136 permits the conveyor chain 126 to pass around sprockets while the rigid mounting of the arm 140, which supports the spacer element 142, permits the spacing between the support elements 138 and 142 to remain constant.
  • the spacing between spacer units 128 is the same as that of the spacing of the elements of the lower conveyor 68 and the upper conveyor 106.
  • conveyor chains 70 may be mounted on any suitable sprocket arrangement and all that is required is that the chains 70 include drive sprockets 144 which are carried by a driven shaft 146.
  • the conveyor chains 108 of the upper conveyor 106 may be supported in any desired sprocket arrangement except that the chains must have a horizontal lower run.
  • the sprockets do include a drive sprocket 148 for each of the chains 108.
  • the drive sprockets 148 are carried by a drive shaft 150.
  • the spacing device 124 has the conveyor chains 126 thereof mounted on any desired sprocket arrangement which will permit the passage of the spacing units as required, and the only limitation is that the conveyor chains 126 must have a horizontal lower run. In other words, the upper runs of the chains 70 and the lower runs of the chains 108 and 126 must be parallel to one another and to the path of movement of the clusters through the wrapping station 40.
  • the sprockets for the conveyor chains 126 include drive sprockets 152 which are carried by a drive shaft 154.
  • the mounting of the conveyor chains 118 provide a different problem.
  • the general mounting of the chains 118 above the path of movement of the clusters is variable.
  • the path of the conveyor chains 118 generally in alignment with the path of movement of the clusters must be controlled as shown in Figure 5.
  • the spacing of the draw members is greater than the spacing of the elements of the upper and lower conveyors and the spacing device, there must be provided means for absorbing this extra spacing beneath the path of the clusters and this is specifically shown in Figure 7 and will be described in detail hereinafter.
  • the conveyor chains 118 are, however, driven by drive sprockets 156 which are mounted on a drive shaft 158. It is to be noted that the drive shafts 150, 154 and 158 are disposed adjacent one another.
  • the infeed conveyor 32 and the support strips 24 terminate adjacent a pair of combined support and feed rolls 160, 162.
  • These rolls are driven at the same peripheral speed as the infeed conveyor 32, and as the front articles of a cluster C move thereon, they are fed and supported by the rolls 160, 162.
  • the associated front support element engages beneath the articles and serves to support and convey the articles at the same speed as previously fed by the infeed conveyor 32.
  • the rear articles of the cluster pass onto the rolls 160, 162 and out of control of the infeed conveyor 32.
  • the rolls 160, 162 feed the rear articles to the left and before the rear articles pass off of the roll 160, they are engaged by the rear support element 108.
  • the articles of each cluster C are readily transferred from the infeed conveyor 32 to the lower conveyor 68 in an uninterrupted continuous action.
  • the front retainer 110 fully engages the front corner of the cluster at the same time as the front articles.of the cluster are fully ' supported by the front support element so as to prevent the forward tipping of the.articles.
  • the front retainer 110 loosely engages the film 56 and permits the drawing of the film over the new cluster.
  • the resilient pad 114 of the rear retainer 112 engages the upper surface of the rear portion of the cluster and serves to clamp the film 56 thereagainst. At this time, the drawing of the film for the preceding cluster has been completed and the resilient pad 114 now serves to hold the film 56 for the drawing thereof to effect wrapping of the new cluster.
  • spacer elements 138 and 142 follow the draw members 120 and 122 down between the adjacent clusters and the spacer element 142 serves to hold the film against the front of the trailing cluster as is clearly shown in Figure 6.
  • the wrapping station 40 includes a frame 170 which may be of any construction and a portion only thereof is shown in Figure 8.
  • the frame 170 includes frame members 172 which have pivotally mounted thereon support arms 174 which are joined together_by a transverse connecting arm 176.
  • the connecting arm 176 carries an upper support member 178 which, in turn, carries an inverted yoke 180 including the hot wire 168.
  • a cam shaft 182 extends transversely of the machine and carries a cam 184.
  • the cam 184 is engaged by a cam follower 186 which, in turn, is carried by the support arm 174 by way of a bracket 188.
  • the frame 170 also includes frame members 190 having a first transverse rod 192 extending therebetween.
  • a spring 194 extends between the rod 192 and the support member 178 and normally holds the hot wire 168 in a retracted position and the cam follower 186 against the cam 184.
  • a guard unit 196 Since the hot wire 168 is always heated, it is necessary to protect against engagement thereof by the film after the film has been cut. To this end there is provided a guard unit 196.
  • the guard unit 196 is carried by a pair of arms 198 pivotally mounted on the rod 192.
  • the arms 198 carry a bracket 200 which supports a cam follower 202 which engages a cam 204 carried by the cam shaft 182.
  • the guard unit 196 is constantly urged toward a retracted position by means of a spring 206 which extends between a bracket 208 carried by the frame 170 and an arm 210 carried by the bracket 200.
  • the guard unit 196 includes a shield plate 212 which normally overlies the hot wire 168. Further, a flap 214 extends upwardly from the shield plate 212 to wipe against the depending front flap 62.
  • the draw members 120, 122 play no part in the wrapping operation, and it is merely necessary to absorb the extra spacing of the draw members by running the conveyor chains 118 over further sprockets 216, 218, 220 and 222, as shown in Figure 7.
  • the wrapping station includes an auxiliary support 224 which is mounted for movement in an orbital.path 226.

  • auxiliary support 224 carries an air nozzle arrangement 242 for directing an air blast generally longitudinally of the path of movement of the clusters and beneath the same.
  • the auxiliary support 224 moves into position beneath the rear portions of the rear articles of the cluster while the rear support element 80 is still supporting the articles. Once the auxiliary support 224 is in the required supporting position, the rear support element 80 retracts as shown in Figure 10. This is caused by the cam followers 98 engaging the recesses 244 in the cams 100. This assures the arms 76 being pivoted in a clockwise direction by the springs 96.
  • the air nozzle arrangement is operated only for a short period of time and is controlled by a valve arrangement to be described hereinafter.
  • the supporting platform is formed by a pair of transversely extending rods 248 which are fixed against rotation and which are of a slightly lesser diameter than the rollers 246 so that the leading portion of the platform 66 has a step.
  • the front flap 62 is folded beneath the front portion of the cluster.
  • the front support element 78 retracts, as is clearly shown in Figure 11, due to the cam followers 84 going down ramp portions 250 of the cams 86.
  • the springs 88 cause pivoting of the arms 74 to effect this retraction.
  • the front flap 62 is continued to be folded beneath the cluster. Shortly before the rear flap 64 approaches the first rod 248, an air blast from an air nozzle tube 252 is directed against the underside of the flap 64 and holds it tightly against the underside of the cluster. Due to the step arrangement of the leading edge of the platform 66, the leading edge of the flap .64 passes up over the adjacent portion of the flap 62 and over the leading rod 248, as shown in Figure 12.
  • the rear support element 80 may now be retracted since tipping of the rear articles of the cluster is prevented by the spacer element 138.
  • the spacer element 138 now becomes substantially the sole means for advancing the cluster.
  • the resilient pad 114 moves out of engagement with the top of the cluster and the cluster is supported solely by the supporting platform 66.
  • the front flap 62 is folded completely beneath the cluster and at the same time, due to the frictional resistance against movement of the flap 62 over the first rods 248, the wrap W is drawn tightly around the cluster C to form a tight package.
  • the spacing unit 128 begins to elevate and at the same time the related draw member 120 moves around a sprocket 396.into engagement with the lower rear portion of the wrapped cluster, as shown in Figure 7.
  • the draw member 120 now takes over the responsibility of discharging the wrapped cluster off of the supporting platform 66 and moving the same onto a discharge conveyor 254 which is a part of a shrink tunnel (not shown).
  • the discharge conveyor 254 may be of any construction and includes drive sprockets 256 carried by a drive shaft 258. The operation of the wrapping station is now completed.
  • the conveyor chains 34 of the infeed conveyor 32 extend around a suitable pattern of sprockets which include drive sprockets 260, carried by a drive shaft 262.

  • the drive shaft 154 carries a sprocket 288 which drives a sprocket 290 on the drive shaft 150 by means of a chain 292. This completes the drive for the upper part of the wrapping station. It is pointed out here, however, that the relative sizes of sprockets have been varied only for purposes of illustration and the sprockets 148 and 152 are to rotate at the same rate when they are the same diameter and the sprocket 156 is to rotate at a higher speed because of the greater rate of travel of the conveyor chain 118.
  • the drive shaft 146 is driven from the drive shaft 274 by a sprocket 292 on the shaft 274 and a sprocket 294 on the shaft 146, the sprockets 292 and 294 being interconnected by a chain 296.
