- ABSTRACT Method and apparatus for loading stacked labels into a label feed magazine having a retractable label pusher platen behind any old labels thereon.
- a stack of new labels is assembled into a tray-carrier which is slightly smaller in profile than the magazine and which holds the labels in stacked relation.
- the loaded tray-carrier is transported to the magazine and is telescoped therewithin to advance the label stack in the tray-carrier toward the old labels already in the magazine.
- the label pusher platen is repositioned behind the rearmost label in the new label stack and the tray-carrier may be removed rearwardly from the magazine or left in position within the magazine.
- the tray-carrier is preferably made of lightweight disposable material, such as cardboard or plastic, and desirably comprises a" trough having one open end and low sides. After the tray-carrier is loaded with a label stack it may be covered with a shrink film or similar pliant cover which cooperates with the trough to hold the stack in position and to keep it clean.
- German published application 2,116,912 discloses a carousel arranged behind the main label magazine. Supplementary magazines are located in a fan-shaped pattern on the carousel which may be rotated to align a supplemental magazine on the carousel with the main magazine. A plunger then pushes a stack of labels out of the supplemental magazine and into the main magazine.
- This apparatus involves substantial expense and requires complex drive and control mechanisms for proper alignment and feeding and transfer of the label stack from the supplemental magazines into the main magazine.
- German Pat. No. 2,014,410 discloses a conventional label magazine made up of a skeletonized framework consisting of parallel ribs or sticks.
- a supplemental basket-like magazine is also made up of parallel ribs or sticks which are staggered with respect to the ribs of the main magazine and which may be inserted into the gaps between the ribs of the main magazine.
- a pusher within the main magazine may thus be actuated without interference by the ribs of the supplemental magazine.
- the supplemental magazine involves a costly construction which is difficult to handle. It is bulky and does not offer proper protection and coverage for the labels therewithin.
- Another known loading technique involves a rather large main magazine which will store a large supply of labels.
- This magazine has a retractable pusher which may be removed laterally from the path of the labels, whereupon it is drawn rearwardly to reposition it behind an added bundle of stacked labels which are placed in the magazine behind any labels remaining in the magazine.
- This operation is manual and is time consuming and requires skilled personnel to avoid disorientation of the newly added labels with respect to the labels already in the magazine.
- the object of the present invention is to avoid the disadvantages of the known devices and to provide a label loading method and apparatus which can be utilized by unskilled personnel, which will handle large numbers of labels during each filling cycle and in which the labels may be assembled into'a tray-carrier in a loading machine and then covered" to protect'thelabels during transport.
- the tray-carrier has a profile which is slightly smaller than the magazine'to'facilitate its telescopic entry into the magazine for the smooth and accurate alignment of new labels with old labels and unloading of the label stack from the tray-carrier into the main magazine while preserving this alignment.
- a label pusher platen is mounted on the magazine on a sliding hinge by which it may be swung laterally of the magazine and slid rearwardly to be repositioned behind the rearmost label in the new label stack.
- Tray-carriers disclosed herein can be made very cheaply and if made of cardboard or thin plastic, can be disposed of after a single use, or they can be reused if desired.
- the invention is based in part upon the perception that the main magazine will continue to function to feed labels to the label machine during the loading operation and during the telescopic addition of the traycarrier to the main magazine. Accordingly, there is no down time on the machine during the tiime that additional labels are being loaded into the magazine.
- the walls of the tray-carrier are made very thin and the traycarrier has an external profile only slightly smaller than the interior profile of the label magazine. Accordingly, the labels are held almost as snugly by the main magazine as they are by the tray-carrier and the pusher platen will fit with almost the same tolerance in the tray-carrier as in the main magazine.
- the tray-carrier wall thickness is less than 1 mm.
- the label pusher platen is guided for fore and aft and lateral swinging movement with respect to the magazine for fast lateral withdrawal from a position behind the old labels already in the magazine, quick retraction longitudinally of the magazine and quick repositioning behind the rearmost label of the new label stack, without substantial interruption of the feeding movement of the labels from the magazine to the label drum.
- the traycarrier consists of a deep drawn or molded synthetic material such as plastic.
- the traycarrier can be made of cardboard. Accordingly, the costs of production are kept very low. The low cost of the label carriers makes it practical to have enough of the tray-carriers available so that they can be loaded by the label manufacturer and used to transport the labels from the label manufacturer to the label user and then thrown away or returned for reloading.
- tray-carrier of reusable material such as sheet metal, particularly where the tray-carrier is to be used only as a loading jig intended to be refilled with label stacks outside of but near the labeling machine.
- Thelabels are typically preprinted, cut labels carrying brand markings and advertising andinformational matter.
- the labels within contemplation of the present invention can also consist of foil for bottle neck wrapping purposes and hence they need not consist of paper, nor be preprinted.
- tray-carriers embodying the invention consist of the combination of a channel-shaped bottom trough open at one end and a cover element, such as shrink film or cardboard, detachably fastened over said trough and which covers the label stack within the trough and also covers the open end of the trough, thus to protect the labels during transit and to provide a reinforcement for the package.
- cover portion of the combined two-piece tray-carrier is usually removed shortly before or just after the insertion of the traycarrier into the label magazine.
- tray-carrier are provided with hinged flaps flexibly connected to the tray-carrier walls at the open end thereof and which may be swung between open and closed position to provide support for the stacked labels after removal of the tray cover and until the tray-carrier is loaded into the main magazine.
- FIG. I is a somewhat diagrammatic perspective view subdivided on broken lines longitudinally therethrough to illustrate in this single view two embodiments of tray-carriers incorporating the invention. In this figure details of the stiffening ribs are only partially illustrated.
- FIG. 2 is an end view again subdivided by broken lines to indicate two different embodiments of a slightly different form of tray-carrier adapted to contain a stack of bottle neck or shoulder labels.
- FIG. 3 is a plan view of a label magazine containing a supply of nearly exhausted or old stacked labels and into which a tray-carrier containing a fresh or new stack of labels has been telescopically inserted.

- FIG. 15 is a diagrammatic view following FIG. 14 and illustrating removal of the tray-carrier rearwardly from the loaded magazine, the pusher platen holding the labels against movement with the tray-carrier.
- the label magazine 20 shown in FIGS. 3, 4, 5, l3, l4 and 15 may typically be supported on a table 21 by posts 22, as best shown in FIGS. 3 and 4, and feeds successive precut stacked labels to a label drum 23 as shown in FIGS. l3, l4 and 15, or to a swinging adhesion pad 24 as shown in FIG. 3, in accordance with well known prior art techniques.
- Label magazine 20 comprises a frame 25 to which longitudinally extending ribs or sticks 26 are fastened to form a skeletonized magazine. The foremost ends of the ribs 26 are provided with nibs or flanges 27 against which the foremost label 28 in the magazine abuts, pending extraction of said label from the label magazine by the label drum 23 or adhesion pad 24.
- FIG. 5 also illustrates a second label magazine 31 mounted above magazine 20.
- the labels 32 in magazine 20 are typically square in cross section for application to the body of a bottle, whereas the labels 33 in magazine 31 are curved and shaped especially to fit the shoulder or neck of the bottle.
- Magazine 20 is mounted on a set of brackets 34 and magazine 31 is mounted on a similar set of brackets 35.
- Both sets of brackets 34, 35 are slidably clamped to a pair of posts 22 and are adjustable thereon for proper orientation with separate label drums 23 or adhesion pads 24 by which the labels are transferred from the magazines to the bottles.
- the respective brackets 34, 35 are provided with adjustable clamps having thumb nuts 36.
- Magazines 20, 31 as just described are conventional and the prior art provides such magazines with label pusher platens which are spring loaded to maintain pressure on the rear of the label stack to advance the labels forwardly in the magazine.
- label pusher platens are shown in U.S. Pat. Nos. 3,537,934 and 3,567,559, for example.
- label pusher platens are also provided, but these are mounted on sliding hinges to facilitate their utilization with the tray-carriers embodying the invention.
- label magazine 20 is provided with a label pusher platen 37 and label magazine 31 is provided with a label pusher platen 38.
- These platens 37, 38 have a novel mounting on their respective magazines, as best shown in FIGS. 3, 4 and 5.
- the respective magazines are provided along corresponding lower corners with longitudinally extending guide tubes or guideways 41, 42.
- Guide tubes 41, 42 are connected by, suitable brackets 43 to magazine frame 25, as shown in FIGS. 3 and 4.
- the respective platens 37, 38 have support arms 44,
- the platen may then be swung laterally'back-to its fullline position (FIG. 5), and in the direction of arrow 52 t'o be repositioned behind the rearmost label -in the new label stack and in alignment with. the path-of label movement.
- the sliding hinges 46, 47 are connected to ends of cables53which.desirably pass through the hollowinterior. ofthe. guidewaytubes.4l, 42 and are reeved at one endofthe guidewaysover pulleys 54 and at the, other end over spring loadedpulleys- 55.
- the spring loaded pulleys Si-exert tension on the cables 53 to bias the platens 37, 38 to move in thedirection of 'arrow 56 in FIG. v13, so as to exert. continuous advancing. pressure tothelabel stack. l
- Arms 44, 45 are long-enough to clear the sides of 'the tray-carriers, as shown inFIG. 5.
- One tray-carrier identified by reference character 57 is illustrated .above and to the left of the broken lines 58 and another. embodiment 59 is shown below and t0 the right .Of the broken lines 58. Both traycarriersy57, 59, have similarfeatures.
- tray-carriers are made of nolcled thindeep drawnfsynthetic or plastic sheet material such as polyethylene.
- Ribs 66 interconnect with the side wall 63, as
- FIG. 1 This structure gives the bottomwall of the tray-carrier substantial strength and rigidity, notwithstanding the thinness of the material.
- side wall 63 is desirably curved in vertical section, as illustrated in FIG. 1, thus to provide added strength for this thin-walled member.
- Rear wall 64 may also be provided with an upright channel 67 for added strength, and to provide a space to receive the platen behind the rearmost label in the label stack.
- the bottom wall 62 of the tray-carrier is also provided with a longitudinal extending channel 68 which mates with a corresponding rib 26 of the magazine.
- rib functions as a track upon which the traycarrier 59 may be slid longitudinally of the magazine.
- Channel or groove 68 greatly increases the strength of the thin-walled plastic material, as well as functioning as a guide during sliding movement of the tray carrier.
- tray-carrier 57 which is also shown in FIG. 1, has a very similar construction. The differences are primarily in specific details such as the fact that the groove or channel 71 is somewhat wider and flatter than channel 68. This provides a broader floor for the label stack and eliminates the need for additional longitudinal ribs such as ribs 65 which are provided in the tray-carrier 59.
- FIG. 1 also illustrates the fact that the rear wall 72 of load carrier 57 may be slightly bulged rearwardly, without the channel 67 provided at the rear wall 64 of the I load carrier 59. This bulge adds strength and receives the pusher platen behind the 'rearmost label in the stack. i
- tray-carriers 57, 59 are provided Withrear end walls 72, 64, they have no front end wallsThe front ends of the tray-carriers 57, 59 are left open to facilitate discharge of the label stacks from the tray-carriers into the magazines.
- FIG. 1 also illustrates the optional feature of providing the side walls 63 of the tray-carriers with hinged end flaps 73 which may be swung between the position shown in FIG. 1 and in the direction of arrows 74 of FIG. 1 1 to their positions shown in that figure in which a label stack can be loaded into and dispensed from the tray-carrier.
- n has no frontwall.
- the bottom Wall of the tray-carriers are shaped somewhat on a curve to match the configuration of the neck or shoulder lablels 33, whereas the tray-carriers shown in FIG. 1 have a substantially flat bottom to match the body labels 32 shown in FIG. 5.
- the tray-carriers for the shoulder or neck labels are very similar to the tray-carriers for the body labels.
- a cover 76 is wrapped around the loaded traycarrier.
- Cover 76 makes up the second part of a twopart carrier and functions to reinforce the relatively fragile thin wall 63 of the tray-carrier and covers the otherwise open front end of the tray-carrier, thus giving the entire package greater stability and strength.
- the cover 76 keeps the label stack 77 clean and free of dirt, etc., during transport of the package.
- FIGS. 10 through 12 illustrate how a tray-carrier, for example tray carrier 57, is loaded with labels coming from, a label manufacturing machine 78.
- the traycarrier 57 is mounted on a support 81 in the path of labels coming from the machine 78 in the direction of arrow 82.
- a label stack 77 will thus be assembled either automatically or by hand into the tray-carrier 57.
- FIG. 11 illustrates the utilization of an opening tool 83 to spread the end flaps 73 of the tray carrier 57 prior to entry of the labels into the tray-carrier.
- the opening tool 83 spreads the flaps 73 in the direction of arrow 74.
- FIGS. 2, 12 and 16 show how cover 76 completes the two-part loaded tray-carrier.
- FIGS. 10 through 12 may occur at a label manufacturing plant which may be remote from the label applying machine.
- the loaded tray-carrier 57 is protected from the elements by cover 76 and is sufficiently strong and rigid to withstand transport and shipment.
- FIGS. 13, 14 and 15 The loading of the label stack 77 from a tray-carrier such as tray carrier 57 into a magazine such as magazine 20 is illustrated in FIGS. 13, 14 and 15.
- FIG. 13 illustrates the situation where old labels 32 already in the label magazine. 20 have been almost depleted therefrom and there is adequate room to receive tray-carrier 57 and its label stack load 77.
- Tray-carrier 57 is then telescopically inserted into the magazine 20 by first moving it in the direction of arrow 86 in FIG. 13, pursuant to which the side walls 63 of the tray-carrier are snugly embraced by the side wall ribs 26 of the magazine, as shown in FIG. 5.
- Traycarrier 57 is then slid forwardly in the direction of arrow 56 to telescope the tray-carrier into the magazine 20.
- the pressure platen behind the old labels 32 continues to feed labels to the label drum 23.
- platen 37 is swung laterally in the direction of arrow 48 in FIGS. 14 and 5 to clear it from the path of label advance and any remaining gap between the foremost label in new label stack 77 and rearmost label in old label stack 32 is taken up by pushing the tray carrier 57 forwardly in the direction of arrow 56.
- Platen 33 is now slid rearwardly in the direction of arrow 51 until it is behind the rearmost label in the stack 77 and it is then swung in the direction of arrow 52 to insert it in the channel 67 or in the bulge 72 formed in the rear wall of the tray-carrier.
- the tension of spring loaded pulley 55 is then allowed to push the platen against the rear of stack 77 for continued pressure feed of all of the labels now in the magazine.
- tray-carrier 57 may be left in the magazine in its condition shown in FIG. 14, it is usually advantageous to immediately remove the tray-carrier 57 by pulling it rearwardly in the direction of arrow 87 as shown in FIG. 15, while the platen 37 keeps the label stack 77 from retracting with the tray-carrier 57. The operator may maintain pressure on the platen 37, or directly on the stack 77, with his other hand. Tray-carrier 57 may then be discarded or returned to the label manufacturing plant where it is reloaded as shown in the sequence illustrated in FIGS. 10-12, inclusive.
- the operation of loading the tray carrier 57 into the magazine 20 is extremely simple and may be performed by unskilled personnel.
- the configuration and size of the tray-carrier and its telescopic relationship with the magazine 20 insures against any dislocation of the labels in stack 77 with respect to the labels in stack 32, so that the stacks 32, 77 are integrated smoothly and in substantially perfect alignment, without interruption of the continuous operation of the labeling machine.
- FIG. 6 illustrates a modified form of tray-carrier 88 which comprises a trough-shaped lower part 91 and a complementary trough-shaped upper part 92.
- the configuration illustrated in FIG. 6 is for the receipt of rectangular body labels.
- the lower part 91 consists of cardboard panels which are shaped as an open-topped trough.
- the rear of the trough (not shown in FIG. 6) has a rear end wall.
- the front end of the tray-carrier 91 is provided with a bottom hinged flap 93 and side hinged flaps 94 which perform functions similar to that of the hinged flaps 73 on tray-carrier 57. Accordingly, during transport of the tray-carrier, these flaps are closed to confine the label stack 77 therewithin.
- the upper part 92 of this tray-carrier may also consist of shrink film such as the shrink film cover 76 of the previously described embodiments. If desired, the upper corner of the label stack 77 may be provided with reinforcing cardboard angle strips 95 to protect the label edges which would otherwise be exposed to damage.
- FIGS. 7, 8 and 9 show a modified embodiment of tray-carrier in which the tray-carrier 96 is made up of cardboard panels hingedly connected to form a generally tubular envelope for the label stack 77 therewithin.
- the cardboard material of the tray-carrier is inexpensive, offers good protection for the label stack during transport and enables easy and quick reloading of the label magazine.
- the tray-carrier 96 consists of a series of hingedly interconnecting panels which form an almost closed tube having open ends. Bottom panel 97 is hingedly connected to side panels 98 which are in turn connected to narrow top flaps or panels 99. Panels 99 are not wide enough to meet at the top of the carrier, thus leaving a slot 102 therebetween.
- the label stack 77 is received within the tube after which separate end panels 103 are interfitted within the otherwise open ends of the tube.
- the tray-carrier is sealed with an adhesive tape 104 which adhesively connects to the proximate margins of the top flaps 99 and spans across the slot 102, thus to close the slot and protect the label stack therewithin.
- an end portion 105 of tape 104 is brought around to adhere against the bottom wall 97 of the tray-carrier and has its extreme end at 106 folded back upon itself to provide an exposed tear tab.
- a medial portion of the tape 104 may be overlaid with foil or a non-adhering tape strip 107 to overlie the slot 102 to prevent adherance of adhesive portions of i the tape to the exposed edges of the labels in the label stack 77 within the tray-carrier.
- the tape 104 could be provided with a non-adhesive medial zone in the area otherwise covered by the strip 107.
- the endmost labels in the label stack 77 could function as end closure panels, if such labels have sufficient strength and substance.
- FIG. 9 shows substantially the same arrangement as FIGS. 7 and 8, except that the bottom wall 97a has an offset portion 108 to accept the downwardly projecting rib portion 1 11 of the shoulder or neck labels for which this particular tray-carrier 96A is designed.
- the reference characters are otherwise the same as in FIGS. 7
- the thickness of the walls 97, 98, 99 can be limited to 0.20.3 mm.
- the fact that the adhesive tape 104 binds or presses the cardboard panels snugly against the sides of the label stack 77 provides mutual support by the label stack for the tray-carrier and the tray-carrier for the label stack.
- the thin walls of the tray-carrier 96 makes it readily telescopically receivable within the magazines 20, 31 inasmuch as there is usually a clearance of about 2 mm. between the interior walls of the magazine and the edges of the labels in stack 77.
- the tray-carrier illustrated in FIGS. 7-9 is easily opened.
- the adhesive tape 104 is first removed by pulling on tab 106. This will automatically also remove the end closure panel 103 which adheres to the tape. Thus a simple pull on the tape will open the end wall of the tray-carrier and will also open the slot 102.
- the adhesive tape 104 will be completely removed and the label pusher platen will be retracted and positioned behind the rearmost label in the stack 77.
- the flaps 99 can be bent backwardly along their hinged connection to the top edges of the side panels 98 to leave ample room for passage of a pusher platen, such as platens 37, 38 of FIG. 5. These platens may have their dimension changed to accommodate the configuration of the traycarrier 98.
- some tray-carriers may have sides, others may have low sides, and in some one or another side may be omitted.
- the platens and their support arms will be shaped accordingly.
- a method of loading stacked labels into a label feed magazine and feeding said labels into a label machine, said magazine having a retractable label pusher platen behind old labels therein and in which method the magazine will continue to feed old labels to a label machine during the loading operation said method comprising the steps of assembling a stack of new labels in an open-ended tray-carrier which is slightly smaller in profile than the magazine and which holds the new labels in stacked relation, transporting the loaded traycarrier to the magazine, telescoping the loaded openended tray-carrier with its open end foremost within the magazine, advancing the stack of new labels in the tray-carrier through its open end and toward and against old labels already in the magazine while the magazine. continues to feed old labels to the label machine and repositioning the label pusher platen behind the stack of new labels for feed of all said labels.
- traycarrier is provided with means for restraining loss of said label stack during transport of the tray-carrier.
- traycarrier comprises a cardboard box having a bottom and sides from which said flaps extend, the ends of said box being closed only by said end closure panels.

US. Patent Oct. 28, 1975 METHOD AND APPARATUS FOR TRAY LOADING OF LABELS INTO LABEL MAGAZINES BACKGROUND OF THE INVENTION United States patent Nos. 3,537,934 and 3,567,559 show labeling machines with label magazines by which cut and stacked labels are fed to the labeling drum of the machine. In the apparatus shown in these patents, small bundles of stacked labels are periodically added to the label magazines in a manual operation. This is a time consuming operation and frequently causes problems because unskilled personnel may not properly orient the bundles in the magazine, thus resulting in improper label transfer and interruption of machine operation.
Prior attempts to improve the loading technique for such label magazines have not been commercially successful, although some of these techniques have been published. See, for example, German patent 2,014,410 and German published application 2,116,912. German published application 2,116,912 discloses a carousel arranged behind the main label magazine. Supplementary magazines are located in a fan-shaped pattern on the carousel which may be rotated to align a supplemental magazine on the carousel with the main magazine. A plunger then pushes a stack of labels out of the supplemental magazine and into the main magazine.
' This apparatus involves substantial expense and requires complex drive and control mechanisms for proper alignment and feeding and transfer of the label stack from the supplemental magazines into the main magazine.
German Pat. No. 2,014,410 discloses a conventional label magazine made up of a skeletonized framework consisting of parallel ribs or sticks. A supplemental basket-like magazine is also made up of parallel ribs or sticks which are staggered with respect to the ribs of the main magazine and which may be inserted into the gaps between the ribs of the main magazine. A pusher within the main magazine may thus be actuated without interference by the ribs of the supplemental magazine. In such a device the supplemental magazine involves a costly construction which is difficult to handle. It is bulky and does not offer proper protection and coverage for the labels therewithin.
Another known loading technique involves a rather large main magazine which will store a large supply of labels. This magazine has a retractable pusher which may be removed laterally from the path of the labels, whereupon it is drawn rearwardly to reposition it behind an added bundle of stacked labels which are placed in the magazine behind any labels remaining in the magazine. This operation is manual and is time consuming and requires skilled personnel to avoid disorientation of the newly added labels with respect to the labels already in the magazine.
SUMMARY OF THE INVENTION The object of the present invention is to avoid the disadvantages of the known devices and to provide a label loading method and apparatus which can be utilized by unskilled personnel, which will handle large numbers of labels during each filling cycle and in which the labels may be assembled into'a tray-carrier in a loading machine and then covered" to protect'thelabels during transport. The tray-carrier has a profile which is slightly smaller than the magazine'to'facilitate its telescopic entry into the magazine for the smooth and accurate alignment of new labels with old labels and unloading of the label stack from the tray-carrier into the main magazine while preserving this alignment. A label pusher platen is mounted on the magazine on a sliding hinge by which it may be swung laterally of the magazine and slid rearwardly to be repositioned behind the rearmost label in the new label stack.
Tray-carriers disclosed herein can be made very cheaply and if made of cardboard or thin plastic, can be disposed of after a single use, or they can be reused if desired.
The invention is based in part upon the perception that the main magazine will continue to function to feed labels to the label machine during the loading operation and during the telescopic addition of the traycarrier to the main magazine. Accordingly, there is no down time on the machine during the tiime that additional labels are being loaded into the magazine.
For the purposes of the present invention, the walls of the tray-carrier are made very thin and the traycarrier has an external profile only slightly smaller than the interior profile of the label magazine. Accordingly, the labels are held almost as snugly by the main magazine as they are by the tray-carrier and the pusher platen will fit with almost the same tolerance in the tray-carrier as in the main magazine. In practice, the tray-carrier wall thickness is less than 1 mm.
The label pusher platen is guided for fore and aft and lateral swinging movement with respect to the magazine for fast lateral withdrawal from a position behind the old labels already in the magazine, quick retraction longitudinally of the magazine and quick repositioning behind the rearmost label of the new label stack, without substantial interruption of the feeding movement of the labels from the magazine to the label drum.
In certain embodiments of the invention the traycarrier consists of a deep drawn or molded synthetic material such as plastic. In other embodiments the traycarrier can be made of cardboard. Accordingly, the costs of production are kept very low. The low cost of the label carriers makes it practical to have enough of the tray-carriers available so that they can be loaded by the label manufacturer and used to transport the labels from the label manufacturer to the label user and then thrown away or returned for reloading.
It is also possible to fabricate the tray-carrier of reusable material such as sheet metal, particularly where the tray-carrier is to be used only as a loading jig intended to be refilled with label stacks outside of but near the labeling machine.
Thelabels are typically preprinted, cut labels carrying brand markings and advertising andinformational matter. However, the labels within contemplation of the present invention can also consist of foil for bottle neck wrapping purposes and hence they need not consist of paper, nor be preprinted.
Some of the tray-carriers embodying the invention consist of the combination of a channel-shaped bottom trough open at one end and a cover element, such as shrink film or cardboard, detachably fastened over said trough and which covers the label stack within the trough and also covers the open end of the trough, thus to protect the labels during transit and to provide a reinforcement for the package. The cover portion of the combined two-piece tray-carrier is usually removed shortly before or just after the insertion of the traycarrier into the label magazine.
Some embodiments of the tray-carrier are provided with hinged flaps flexibly connected to the tray-carrier walls at the open end thereof and which may be swung between open and closed position to provide support for the stacked labels after removal of the tray cover and until the tray-carrier is loaded into the main magazine.
Other objects, features and advantages of the invention will appear from the disclosure hereof.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structure. The scope of the invention is defined in the claims appended hereto.
In some instances like parts are given the same reference characters in the several views.
The label magazine 20 shown in FIGS. 3, 4, 5, l3, l4 and 15 may typically be supported on a table 21 by posts 22, as best shown in FIGS. 3 and 4, and feeds successive precut stacked labels to a label drum 23 as shown in FIGS. l3, l4 and 15, or to a swinging adhesion pad 24 as shown in FIG. 3, in accordance with well known prior art techniques. Label magazine 20 comprises a frame 25 to which longitudinally extending ribs or sticks 26 are fastened to form a skeletonized magazine. The foremost ends of the ribs 26 are provided with nibs or flanges 27 against which the foremost label 28 in the magazine abuts, pending extraction of said label from the label magazine by the label drum 23 or adhesion pad 24.
FIG. 5 also illustrates a second label magazine 31 mounted above magazine 20. The labels 32 in magazine 20 are typically square in cross section for application to the body of a bottle, whereas the labels 33 in magazine 31 are curved and shaped especially to fit the shoulder or neck of the bottle. Magazine 20 is mounted on a set of brackets 34 and magazine 31 is mounted on a similar set of brackets 35. Both sets of brackets 34, 35 are slidably clamped to a pair of posts 22 and are adjustable thereon for proper orientation with separate label drums 23 or adhesion pads 24 by which the labels are transferred from the magazines to the bottles. For alignment purposes the respective brackets 34, 35 are provided with adjustable clamps having thumb nuts 36.
The respective platens 37, 38 have support arms 44,
45 outside of the magazines 20, 31 and these arms are coupled at their: ldwer ends to the guideways 41, 42 by sliding hinges 46, 47. As best shown in FIG. 5, the arms 44, 45 extend upwardlyfrom the sliding hinges 46, 47
so as to clear the frame 25 of the magazine and are rethickness below 1 mm. I c I While thin sheetmetal eouldbe used, as the material spectively connected to the upper portion of the pusher platens 37, 38. T heplatens 37, 38are piv'jotallymov able on their hinges 46, 47 and may be swung laterally in the direction of arrow 48 to the broken line position of platen- 37, as 'shownin FIG..-5. When swung to its broken line position, the platen maybe moved longitudinally of the magazine bysliding hinge 46 along the guideway 4l in-the direction of, arrow 51 inFIG. 14.
As illustrated in FIG. .14, the platen may then be swung laterally'back-to its fullline position (FIG. 5), and in the direction of arrow 52 t'o be repositioned behind the rearmost label -in the new label stack and in alignment with. the path-of label movement.
The sliding hinges 46, 47 are connected to ends of cables53which.desirably pass through the hollowinterior. ofthe. guidewaytubes.4l, 42 and are reeved at one endofthe guidewaysover pulleys 54 and at the, other end over spring loadedpulleys- 55. The spring loaded pulleys Si-exert tension on the cables 53 to bias the platens 37, 38 to move in thedirection of 'arrow 56 in FIG. v13, so as to exert. continuous advancing. pressure tothelabel stack. l
-It is animportant feature of v the invention that'the tray-carriers, such as 57, 59 of FIG. 1, be only slightly smaller-in profile thanthejnterior space within the label magazinewithin which it is-to fiLThis-invention takes advantage-of the fact, moreover, that conventional magazines 20, 31 ,willtypically be slightly larger in their interior dimensionsthan the profile of the label stacks 32, 33 which will be Positionedtherewithin. Aocordingly, there is, a slight clearance between the edges without binding against its sides and the tray-carrierv will nevertheless be freely and slidably receivabletelescopically within the confines of the label magazines 20, 31. In practice, itis desirable to keep t ay w ll.
for the t ra y;- c,arriers,;it has been found advantageous fromthe standpoint of ,cost and disposability-to make the itra y-carriers out of inexpensive plastic, cardboard orthe like. Inthe, embodiments shownin FIG. 1, tl'1e respectivealternative forms of tray-carriers. 57, 59 are made of nolcled thindeep drawnfsynthetic or plastic sheet material such as polyethylene.
' ribs 66. Ribs 66 interconnect with the side wall 63, as
illustrated in FIG. 1. This structure gives the bottomwall of the tray-carrier substantial strength and rigidity, notwithstanding the thinness of the material.
Moreover, side wall 63 is desirably curved in vertical section, as illustrated in FIG. 1, thus to provide added strength for this thin-walled member. Rear wall 64 may also be provided with an upright channel 67 for added strength, and to provide a space to receive the platen behind the rearmost label in the label stack.
In preferred embodiments of the structure shown in FIG. 1, the bottom wall 62 of the tray-carrier is also provided with a longitudinal extending channel 68 which mates with a corresponding rib 26 of the magazine. Such rib functions as a track upon which the traycarrier 59 may be slid longitudinally of the magazine. Channel or groove 68 greatly increases the strength of the thin-walled plastic material, as well as functioning as a guide during sliding movement of the tray carrier.
The alternate form of tray-carrier 57 which is also shown in FIG. 1, has a very similar construction. The differences are primarily in specific details such as the fact that the groove or channel 71 is somewhat wider and flatter than channel 68. This provides a broader floor for the label stack and eliminates the need for additional longitudinal ribs such as ribs 65 which are provided in the tray-carrier 59.
FIG. 1 also illustrates the fact that the rear wall 72 of load carrier 57 may be slightly bulged rearwardly, without the channel 67 provided at the rear wall 64 of the I load carrier 59. This bulge adds strength and receives the pusher platen behind the 'rearmost label in the stack. i
While the respective tray-carriers 57, 59 are provided Withrear end walls 72, 64, they have no front end wallsThe front ends of the tray-carriers 57, 59 are left open to facilitate discharge of the label stacks from the tray-carriers into the magazines.
FIG. 1 also illustrates the optional feature of providing the side walls 63 of the tray-carriers with hinged end flaps 73 which may be swung between the position shown in FIG. 1 and in the direction of arrows 74 of FIG. 1 1 to their positions shown in that figure in which a label stack can be loaded into and dispensed from the tray-carrier.
Consideringfir'sttray-carrier 59, it has a bottom-62,
a side wall 63 and a rearwall 64. n has no frontwall.
Theoverall, height of the side wall 63 and rear wan 64 is quite shallow because it is'intende'd that the traycarrier in. itsentirety be madein two parts, the" lower part being shownin FIG. land an upper part consisting simply of a cover or wrapping filmtwhichenv elopes a Moreover, the upper edges of the side walls 63 of the tray-carriers may be provided with turned over flanges 75 to further strengthen the upper edge of the traymet In the specific configuration of FIG. 2, the bottom Wall of the tray-carriers are shaped somewhat on a curve to match the configuration of the neck or shoulder lablels 33, whereas the tray-carriers shown in FIG. 1 have a substantially flat bottom to match the body labels 32 shown in FIG. 5. Other than dimensions and slight modification in configuration, the tray-carriers for the shoulder or neck labels are very similar to the tray-carriers for the body labels.
As best shown in FIGS. 2 and 16, after the label stack 77 is loaded into the tray-carrier 57, as hereinafter described, a cover 76 is wrapped around the loaded traycarrier. Cover 76 makes up the second part of a twopart carrier and functions to reinforce the relatively fragile thin wall 63 of the tray-carrier and covers the otherwise open front end of the tray-carrier, thus giving the entire package greater stability and strength. Moreover, the cover 76 keeps the label stack 77 clean and free of dirt, etc., during transport of the package.
FIGS. 10 through 12 illustrate how a tray-carrier, for example tray carrier 57, is loaded with labels coming from, a label manufacturing machine 78. The traycarrier 57 is mounted on a support 81 in the path of labels coming from the machine 78 in the direction of arrow 82. A label stack 77 will thus be assembled either automatically or by hand into the tray-carrier 57. FIG. 11 illustrates the utilization of an opening tool 83 to spread the end flaps 73 of the tray carrier 57 prior to entry of the labels into the tray-carrier. The opening tool 83 spreads the flaps 73 in the direction of arrow 74.
When the tray-carrier 57 has a full label stack 77, it is transferred in the direction of arrow 84 (FIG. 12) into a shrink tunnel 85 where a heat shrinkable film forming the cover 76 is shrunk about the loaded traycarrier 57. FIGS. 2, 12 and 16 show how cover 76 completes the two-part loaded tray-carrier.
The operations illustrated in FIGS. 10 through 12 may occur at a label manufacturing plant which may be remote from the label applying machine. The loaded tray-carrier 57 is protected from the elements by cover 76 and is sufficiently strong and rigid to withstand transport and shipment.
The loading of the label stack 77 from a tray-carrier such as tray carrier 57 into a magazine such as magazine 20 is illustrated in FIGS. 13, 14 and 15. FIG. 13 illustrates the situation where old labels 32 already in the label magazine. 20 have been almost depleted therefrom and there is adequate room to receive tray-carrier 57 and its label stack load 77. First the cover 76 is removed from the tray-carrier, thus to expose the label stack 77. Tray-carrier 57 is then telescopically inserted into the magazine 20 by first moving it in the direction of arrow 86 in FIG. 13, pursuant to which the side walls 63 of the tray-carrier are snugly embraced by the side wall ribs 26 of the magazine, as shown in FIG. 5. Traycarrier 57 is then slid forwardly in the direction of arrow 56 to telescope the tray-carrier into the magazine 20.
Meanwhile, the pressure platen behind the old labels 32 continues to feed labels to the label drum 23. As soon as the tray-carrier 57 is almost fully inserted into the magazine, platen 37 is swung laterally in the direction of arrow 48 in FIGS. 14 and 5 to clear it from the path of label advance and any remaining gap between the foremost label in new label stack 77 and rearmost label in old label stack 32 is taken up by pushing the tray carrier 57 forwardly in the direction of arrow 56. Platen 33 is now slid rearwardly in the direction of arrow 51 until it is behind the rearmost label in the stack 77 and it is then swung in the direction of arrow 52 to insert it in the channel 67 or in the bulge 72 formed in the rear wall of the tray-carrier. The tension of spring loaded pulley 55 is then allowed to push the platen against the rear of stack 77 for continued pressure feed of all of the labels now in the magazine.
While the tray-carrier 57 may be left in the magazine in its condition shown in FIG. 14, it is usually advantageous to immediately remove the tray-carrier 57 by pulling it rearwardly in the direction of arrow 87 as shown in FIG. 15, while the platen 37 keeps the label stack 77 from retracting with the tray-carrier 57. The operator may maintain pressure on the platen 37, or directly on the stack 77, with his other hand. Tray-carrier 57 may then be discarded or returned to the label manufacturing plant where it is reloaded as shown in the sequence illustrated in FIGS. 10-12, inclusive.
It is to be noted that the operation of loading the tray carrier 57 into the magazine 20 is extremely simple and may be performed by unskilled personnel. The configuration and size of the tray-carrier and its telescopic relationship with the magazine 20 insures against any dislocation of the labels in stack 77 with respect to the labels in stack 32, so that the stacks 32, 77 are integrated smoothly and in substantially perfect alignment, without interruption of the continuous operation of the labeling machine.
FIG. 6 illustrates a modified form of tray-carrier 88 which comprises a trough-shaped lower part 91 and a complementary trough-shaped upper part 92. The configuration illustrated in FIG. 6 is for the receipt of rectangular body labels. The lower part 91 consists of cardboard panels which are shaped as an open-topped trough. The rear of the trough (not shown in FIG. 6) has a rear end wall. The front end of the tray-carrier 91 is provided with a bottom hinged flap 93 and side hinged flaps 94 which perform functions similar to that of the hinged flaps 73 on tray-carrier 57. Accordingly, during transport of the tray-carrier, these flaps are closed to confine the label stack 77 therewithin.
The upper part 92 of this tray-carrier may also consist of shrink film such as the shrink film cover 76 of the previously described embodiments. If desired, the upper corner of the label stack 77 may be provided with reinforcing cardboard angle strips 95 to protect the label edges which would otherwise be exposed to damage.
FIGS. 7, 8 and 9 show a modified embodiment of tray-carrier in which the tray-carrier 96 is made up of cardboard panels hingedly connected to form a generally tubular envelope for the label stack 77 therewithin. The cardboard material of the tray-carrier is inexpensive, offers good protection for the label stack during transport and enables easy and quick reloading of the label magazine.
The tray-carrier 96 consists of a series of hingedly interconnecting panels which form an almost closed tube having open ends. Bottom panel 97 is hingedly connected to side panels 98 which are in turn connected to narrow top flaps or panels 99. Panels 99 are not wide enough to meet at the top of the carrier, thus leaving a slot 102 therebetween. The label stack 77 is received within the tube after which separate end panels 103 are interfitted within the otherwise open ends of the tube. The tray-carrier is sealed with an adhesive tape 104 which adhesively connects to the proximate margins of the top flaps 99 and spans across the slot 102, thus to close the slot and protect the label stack therewithin.
As shown in FIG. 8, an end portion 105 of tape 104 is brought around to adhere against the bottom wall 97 of the tray-carrier and has its extreme end at 106 folded back upon itself to provide an exposed tear tab. Moreover, a medial portion of the tape 104 may be overlaid with foil or a non-adhering tape strip 107 to overlie the slot 102 to prevent adherance of adhesive portions of i the tape to the exposed edges of the labels in the label stack 77 within the tray-carrier. Alternatively, the tape 104 could be provided with a non-adhesive medial zone in the area otherwise covered by the strip 107.
Instead of the end panels 103, the endmost labels in the label stack 77 could function as end closure panels, if such labels have sufficient strength and substance.
FIG. 9 shows substantially the same arrangement as FIGS. 7 and 8, except that the bottom wall 97a has an offset portion 108 to accept the downwardly projecting rib portion 1 11 of the shoulder or neck labels for which this particular tray-carrier 96A is designed. The reference characters are otherwise the same as in FIGS. 7
and 8.
In a typical tray-carrier such as shown in FIGS. 7 and 8, as many as seven thousand labels can be assembled into the stack 77 and the thickness of the walls 97, 98, 99 can be limited to 0.20.3 mm. The fact that the adhesive tape 104 binds or presses the cardboard panels snugly against the sides of the label stack 77 provides mutual support by the label stack for the tray-carrier and the tray-carrier for the label stack. The thin walls of the tray-carrier 96 makes it readily telescopically receivable within the magazines 20, 31 inasmuch as there is usually a clearance of about 2 mm. between the interior walls of the magazine and the edges of the labels in stack 77.
The tray-carrier illustrated in FIGS. 7-9 is easily opened. The adhesive tape 104 is first removed by pulling on tab 106. This will automatically also remove the end closure panel 103 which adheres to the tape. Thus a simple pull on the tape will open the end wall of the tray-carrier and will also open the slot 102.
After the opened tray-carrier 96 has been telescopically received within the magazine 20, in the same series of steps illustrated in FIGS. 12-15, the adhesive tape 104 will be completely removed and the label pusher platen will be retracted and positioned behind the rearmost label in the stack 77. The flaps 99 can be bent backwardly along their hinged connection to the top edges of the side panels 98 to leave ample room for passage of a pusher platen, such as platens 37, 38 of FIG. 5. These platens may have their dimension changed to accommodate the configuration of the traycarrier 98.
For example, some tray-carriers may have sides, others may have low sides, and in some one or another side may be omitted. The platens and their support arms will be shaped accordingly.
