Automatic tag attaching apparatus with pivotally mounted tag feed plate

Abstract

Apparatus for automatically attaching tags to articles employs a simplified tag feed mechanism in the form of a pivotally mounted spring-loaded tag feed plate. The plate receives the printed tag from the tag dispenser. The plate, with its tag, and the article to be tagged, are moved together, either manually or by action of a pneumatic cylinder, toward an attaching device such that the needle penetrates the article and the tag at the same time. The attacher is actuated to dispense a fastener through the needle. The spring-loading of the plate then urges the plate away from the needle, allowing the article with its anchored tag to be removed, once the plate clears the needle. The tag dispenser is then actuated to dispense the next printed tag.

Description

The present invention relates to apparatus for automatically attaching preprinted tags of various types to articles and more particularly to an improved apparatus for automatically attaching tags, designed for use with a tag dispensing mechanism such as a tag printer, which includes a simplified tag feed mechanism.

Tags of various types are utilized to label large quantities of many different types of articles, such as clothing. One popular means of attaching tags to articles is by using plastic fasteners. Such fasteners are provided with a T-bar at one end. The T-bar is connected to an enlarged paddle, located at the other end of the fastener, by a thin, flexible filament. The filament is stretched during the fabrication process to give it a high tensile strength.

To attach the tag to an article, a device with a gun-like housing having a protruding hollow slotted metal needle is utilized. The needle is inserted through a pre-punched opening in the tag and penetrates the article to be tagged. The T-bar end of the fastener is then ejected through the needle, such that the T-bar is situated on one side of the tag and article, with the enlarged paddle end on the other side, anchoring the tag to the article.

Hand held tag attaching devices of this type are used widely and commercially available from a number of suppliers. Those devices may be manually operated or power driven, either electrically or pneumatically. Table mounted versions are also commonly utilized, sometimes in conjunction with automatic tag feeding mechanisms which feed separated preprinted tags from a stack to the fastener dispensing device. Circuitry for controlling the tag feed and fastener dispensing operations is provided. See, for example U.S. Pat. No. 3,896,713 entitled “Top-Feeding Automatic Tag-Attaching Machine” issued to Mato on Jul. 29, 1975; U.S. Pat. No. 4,235,161 entitled “Automatic Tag Attaching Apparatus” issued to Kunreuther on Nov. 25, 1980; U.S. Pat. No. 4,718,158 entitled “Automatic Tagging Apparatus and Method Therefor” issued to Charles Block on Jan. 12, 1988; and U.S. Pat. No. 4,781,318 entitled “Tagging Apparatus” issued to Ronald Meyers on Nov. 1, 1988.

Most automatic tagging mechanisms available currently, such as the first three patents mentioned in the previous paragraph, employ a tag feed system which utilizes a pneumatically driven reciprocating slide mechanism. The slide moves preprinted tags, one at a time, from a stack in a hopper to a position where the pre-punched opening in the tag is aligned with the needle. In the Mato and Block mechanisms, the device and hence the needle is advanced toward the tag to insert the needle through the tag opening. In the Kunreuther machine, the attacher is fixed and tag is placed over the needle by moving the slide towards the needle after the tag is aligned.

Another automatic tagging mechanism utilizes a fixed tag attaching device like that of Kunreuther, but employs a moveable suction arm to engage the tag and place it on the needle. The arm carries a suction cup connected to a vacuum. The arm engages a tag in the hopper and transports the tag to the attacher. See U.S. Pat. No. 4,781,318 mentioned above. In the Meyers' apparatus, the vacuum arm is moved thorough a sinuous path that ends in a path section which is parallel to needle of the tag attaching device in order to place the tag over the needle.

The above mentioned automatic tag feed systems require precise adjustment of the vertical and horizontal position of the tag hopper relative to the tag feed means. This is because the opening in the tag is relatively small and the tag must be positioned such that the tag opening aligns exactly with the needle. Because of this, the set up of the machine is time consuming. Each time different size tags are used, readjustment of the hopper position is necessary, requiring considerable machine down time.

In the apparatus with vacuum-type transport means, vacuum as well as electrical power are needed. Further, in a hostile environment, it has been found that tag feeders of this type do not always operate reliably.

An improved vacuum feed mechanism for an automatic tag attaching apparatus is described in co-pending U.S. patent application Ser. No. 10/073,089, filed Feb. 12, 2002, entitled “Improved Automatic Tag Attaching Apparatus”. That tag feed mechanism has a vacuum arm that moves an engaged tag through a simplified path of travel onto a stationary tag support platform. The attacher with its needle is then advanced toward the tag support platform to insert the needle through the tag opening. However, tag hopper positioning is still critical so the hopper is designed to be independently position adjustable in horizontal and vertical directions. A laser light is used to facilitate positioning of the hopper such that the tag is placed on the tag support platform with the opening in alignment with the needle.

Only pre-printed, separated tags can be utilized in systems which feed tags from a stack. In those systems, it is not possible to employ a conventional thermal transfer printer, designed to print tags as needed.

Instead of feeding separate preprinted tags from a stack, some automatic tagging mechanisms are capable of feeding end-to-end connected preprinted tags from a supply roll. However, those machines have the drawback of requiring an automatic cutter or knife to cut the attached tag from the next tag in sequence, before the tagged article can be removed from the machine.

Although using a knife or cutter with sharp blades results in a clean, straight cut, the blades must be continually sharpened. Further, such cutting mechanisms are complicated and may be hazardous to the operator.

Co-pending U.S. patent application Ser. No. 10/059,066, filed Jan. 30, 2002, entitled “Hangtags For Use In An Automatic Attaching Apparatus” discloses an invention that eliminates the necessity of using an automatic cutter in an automatic tag attaching system where the hangtags are connected end-to-end and supplied on a continuous roll. That system overcomes the positioning problems related to feeding tags from a stack. No vacuum or slide tag transfer mechanisms are required. This is accomplished through the use of hangtags that are connected together in a unique way which permits them to be manually separated.

In that system, the hangtags are removed from the supply roll in a continuous strip. The hangtags are connected end-to-end by connecting elements. The lead hangtag is guided into alignment with the attacher needle and attached to the article by the fastener. The next tag in sequence is held while the attached hangtag is separated by simply pulling the tagged article away from the apparatus. In one embodiment, some of the connecting elements between the attached hangtag and the held hangtag are automatically severed, prior to removal of the attached hangtag, making remnoval of the attached hangtag easier. This hangtag connection system permits the hangtags to be used with a conventional thermal transfer printer that prints blank tags as required, without a cutter. The hangtag can be used with or without an automatic attaching device.

The connecting elements disclosed in that patent application are formed so that they can be severed simultaneously by a pull force transferred through the anchored fastener. That force is directed perpendicular to the hangtag ends. By making the portion of the hangtag surrounding the pre-punched fastener receiving opening stronger than the force necessary to simultaneously sever the connecting elements, the hangtag attached to the article by the fastener can be manually separated from the next hangtag by simply removing the article from the tag attaching apparatus by pulling in a direction perpendicular to the hangtag end. This permits the entire tag printing and attaching processes to be fully automated, utilizing hangtags supplied on a continuous roll, without the necessity of an automatic knife or cutter.

While the system described in application Ser. No. 10/059,066 is a great improvement over systems which feed tags from a stack or which require automatic cutters or knives, it still is somewhat complex, having several moving parts and hence being relatively expensive to manufacture. There is therefore a need for a simpler, less expensive tag feed mechanism which can be used with tags which are connected end-to-end and supplied on a continuous roll.

Further, in that apparatus, and in machines like that disclosed in Block U.S. Pat. No. 4,718,158, the tag is fed to a plate which is situated between the article to be tagged and the attacher needle. No matter how thin the tag and plate are, they may interfere with the proper placement of the article relative to the needle.

In those mechanisms, there is a gap into which the article must be situated before it is penetrated by the needle. If the gap is too large, there is the possibility of the operator getting a finger caught in the mechanism. If the gap is too small, large, thick or bulky, articles may not fit into the machine.

In many cases, companies use what is called “an integrated tag” in which brand identification and/or other text is printed on the front surface of the tag and a barcode is located on the rear. In the machine of application Ser. No. 10/059,066, it is only possible to place the barcode on the front of the tag. This is because the garment is placed underneath the machine and the fastener first goes through the tag with the barcode showing and then through the product.

In all conventional automatic tag attaching machines, the tag is placed over the needle. Then the article is penetrated by the needle. Hence, two separate movements are required, one to place the tag on the needle and a second to cause the needle to penetrate the article. My apparatus greatly simplifies the automatic attaching procedure by moving the tag and the article onto the needle in a single motion.

The present invention uses a conventional tag attacher, in which fasteners are supplied on a roll, a conventional computer controlled thermal printer and tags connected together and supplied on a continuous roll, as disclosed in application Ser. No. 10/059,066. The complex reciprocating slide or vacuum arm tag feed mechanisms of prior machines are replaced by a simple, pivotally mounted spring-loaded tag feed plate that receives the tag as it is dispensed and supports the tag in alignment with the attacher needle. The operator places the article to be tagged adjacent the plate and pushes the plate with the received tag, and article, down over the needle such that the tag and article are placed on the needle at the same time. After the plate reaches a position where the tag and article are both penetrated by the needle, the attacher is actuated to dispense the fastener.

Spring-loaded support plates have been used previously with stationary fastener attachers, see U.S. Pat. No. 4,237,779, issued Dec. 9, 1980, entitled “Automatic Attaching Apparatus”. However, the automatic attaching apparatus disclosed in that patent is designed specifically to attach headers to soft goods and therefore lacks the capability for feeding labels into alignment with the needle.

Plates that are mechanically moved into alignment with the needle of a stationary attacher are also known, see, for example, U.S. Pat. No. 4,589,583, issued May 20, 1986, entitled “Automatic Hook Attaching Apparatus”. That apparatus is designed for attaching plastic hooks to merchandise for purposes of display. In that apparatus, the hooks are supplied in a stack. The hooks are removed from the stack, one at a time, by a slide. The side is aligned with the needle using a cam and cam follower arrangement. There is no capability for feeding tags, much less tags that are connected end-to-end and supplied on a roll. The apparatus cannot be used in conjunction with a tag printer.

In the present invention, pivotally mounting the tag feed plate greatly simplifies the tag feed mechanism. In addition, mounting the tag feed plate in this manner provides the operator with better control over the operation of the apparatus because the plate, with the tag and article to be tagged, must be pivoted to a predetermined position before the attacher can be actuated to dispense the fastener.

To complete the tagging process successfully, it is most important that the article be fully seated over the needle. In order to accomplish that, the article must be- held taught as it is placed over the needle. My apparatus includes two different mechanisms for stretching the article to hold it taught as it is placed over the needle. Different mechanisms are provided depending upon whether the article is above or below the plate which receives and supports the tag.

Because the present invention utilizes a much simpler tag feed mechanism, most of the moving parts of the conventional feed mechanisms are eliminated, as is the necessity for moving the tag attacher relative to the feed plate. It provides more secure attaching of the tag because the tag and article are always completely seated on the needle. There is no limitation in the size of the gap between the feed plate and needle. Further, it permits tagging on the rear side of the tag.

It is, therefore, a prime object of the present invention to provide an automatic tag attaching apparatus with a simplified tag feed mechanism.

FIG. 6 is a front view of the plate of FIG. 5 ;

FIG. 7 is a top elevational view of another version of the tag feed plate of the second embodiment; and

FIG. 8 is a front view of the plate of FIG. 7 .

The present invention relates to automatic apparatus for attaching tags to an article, such as an article of clothing. The invention is designed for use with a machine that dispenses a printed tag when actuated. Preferably, the machine is a conventional computer controlled tag and label printer, for example, a TTX 300 or TTX 450 Tag and Label Printer, available from Avery Dennison of Framingham, Massachusetts. However the present invention could be used with a machine which dispenses pre-printed tags or labels.

In either case, the tags or labels (for simplicity, in this specification, the word “tag” will be used to refer to any tag, label or similar product which can be printed upon and attached to an article) are connected end-to-end and supplied on a continuous roll. The tags are connected to each other by unique connecting elements that are designed to be separated manually, without a knife or cutter, by pulling one tag away from the next tag in sequence, while the next tag is held. In this case, the next tag in sequence is held by the internal mechanism of the tag dispenser, as is conventional for such machines. For detailed information regarding the tag connecting system, please refer to co-pending application Ser. No. 10/059,066, mentioned above.

The printed tag is attached to the article by a plastic fastener. The fastener is dispensed through the hollow needle of a tag attacher of conventional design, such as the System 1000 “Swiftacher”, also available from Avery Dennison.

As seen in FIG. 1 , the present invention includes a mechanism, generally designated A, which dispenses printed tags, generally designed B, one at a time from a supply roll 10 . In this case, tags B on roll 10 are preprinted. The tags pass through a holding stage, represented schematically by a pneumatic cylinder 12 with an extendable rod which acts against a stationary anvil 14 . The holding stage securely holds the second tag in sequence, after the first tag is dispensed, but is disabled as a tag is being dispensed. Tags B are dispensed, one at a time, through a slot 16 on the front surface 17 of the housing of tag dispenser A.

Tag dispenser A is mounted on a work surface, such as a table top 18 . Also mounted on table top 18 is the tag attacher, generally designated C.

Tag attacher C has a gun-like body with a hollow slotted metal needle 22 protruding from its front end. Attacher C is fixedly mounted to a platform 24 by bracket 26 . Platform 24 and hence attacher C is position adjustable relative the surface of table top 18 .

Tag attacher C is mounted on platform 24 by bracket 26 such that the attacher body is in a generally upright position with needle 22 parallel to the front surface 17 of the housing of tag dispenser. The tip of needle 22 is located slightly below the plane of slot 16 .

Tag attacher C carries a supply of plastic fasteners in a roll 30 . It includes a depressable trigger 32 . Depression of the trigger causes the “T” bar end of a fastener to be dispensed through needle 22 . After a fastener is dispensed, an additional fastener from roll 30 is automatically fed to the attacher.

A pneumatic cylinder 33 , also mounted on platform 24 , is provided with a retractable rod 34 which carries a part 36 for engaging trigger 32 . Retraction of rod 34 depresses trigger 32 to cause attacher C to dispense a fastener through needle 22 .

A tag feed guide plate, generally designated D, is pivotally mounted to the front surface 17 of housing of tag dispenser A, at a position slightly below slot 16 . Plate D receives a tag as it is dispensed through slot 16 .

Platform 24 which carries attacher C is moveable relative to table top 18 within an enlongated recess in block 25 which is fixed to the table top. Set screws (not shown) are loosened to permit the position of the bracket to be moved relative to block 25 to the desired position. The screws are then tightened to secure the bracket. This permits the position of attacher C, and hence needle 22 , to be adjusted relative to plate D such that the needle is properly aligned with the prepunched hold in the tag B supported on plate D.

As best seen in FIGS. 3 and 4 , plate D includes a base 38 which carries first and second oppositely oriented upside down “L” shaped tag guides 40 , 42 . Guides 40 and 42 are situated on sets of rods 44 , 46 , respectively, which are received in openings in blocks 48 , 50 , respectively, fixed to the bottom of base 38 . Blocks 48 , 50 are provided with set screws 52 (see FIG. 4 ) such that when screws 52 are loosened, rods 44 , 46 can be moved relative to blocks 48 , 50 , to adjust the spacing between guides 40 and 42 such that plate D can easily accommodate tags of different sizes.

Each tag B has a prepunched hole 54 which receives the needle 22 and through which the fastener will extend after it is dispensed from needle 22 . A semi-circular recess 56 on base 38 is situated to provide clearance for the needle and fastener.

Plate D is pivotally mounted to the front surface 17 of dispenser A by rods 60 which extend inwardly from spaced brackets 62 affixed to surface 17 . Base 38 has a pair of spaced brackets 64 which engage rods 60 . Helical springs 66 are situated around rods 60 . The ends of each spring 60 are connected between each pair of brackets 62 , 64 such that plate D is spring-loaded toward its first position, shown in solid in FIGS. I and 2 .

In FIG. 1 the first position of plate D is in a plane substantially perpendicular to and slightly above needle 22 . Plate D can be manually moved by the operator, against the urging of springs 60 , to a second position, as shown in phantom in FIG. 1 . The second position is in a plane which makes an acute angle with the plane of the first position of the plate.

The operation of first preferred embodiment of the invention begins with tag dispenser A being actuated to dispense a single printed tag B through slot 16 . The tag is received between guides 40 and 42 on plate D, with plate D in its first position. Tag B is supported on plate D with hole 54 of the tag in alignment with recess 56 in base 38 and with needle 22 . The next tag in sequence is held by the holding mechanism of the tag dispenser, which in FIG. 1 takes the form of cylinder 12 and anvil 14 .

The operator grasps the ends of the article to be tagged, generally designated E, in his or her hands and spreads the article over the tag on plate D. The operator then moves the article, plate D and the tag together, in a downward direction, toward the second position of plate D, against the urging of springs 66 , such that needle 22 passes through hole 54 in the tag and penetrates article E at the same time. As plate D approaches the second position (shown in phantom in the drawings), the actuator of a switch 68 , mounted on housing surface 17 below slot 16 , is tripped.

Tripping switch 68 energizes cylinder 33 to retract rod 34 and depress trigger 36 of attacher C. This causes a fastener to be dispensed through needle 22 . The fastener anchors the tag on plate D to article E. The operator releases the downward force on plate D which allows springs 66 to move plate D back to its first position. Once plate D clears needle 22 , article E, and the attached tag B, are pulled away from plate D such that the attached tag separates from the next tag in sequence by severing the connecting elements between the tags. The tagged article is removed from the apparatus.

An optical “tag out” sensor 70 , mounted on bracket 71 which extends from the housing of the tag dispenser, may be used to sense the removal of the tagged article. Sensor 70 consists of a light source and a photosensitive detector. The light source sends a beam of light toward plate D. Plate D has a surface which reflects the light back to the detector, when nothing is present above plate D. Thus, when the tag or article is present on plate D, no reflected light is sensed by the detector. However, when article E and the attached tag B are removed, the reflected beam is sensed by the detector. Sensor 70 then actuates the tag dispenser to dispense the next printed tag to plate D.

FIG. 2 illustrates a second preferred embodiment of the invention. This embodiment is similar in most respects to the embodiment shown in FIG. 1 . However, in this embodiment, article E is situated below plate D and tag dispenser A takes the form of a conventional computer controlled thermal tag printer. The printer is supplied with blank tags B from a roll 72 . The tags B pass between print heads 74 , 76 which serve to print each tag before it is dispensed and to hold the next tag in sequence.

Tag plate D, in this embodiment, has a first position which is at small acute angle above a plane perpendicular to needle 22 . The second position of plate D is the same as in the first embodiment.

A pneumatic cylinder 80 is mounted by bracket 82 to the top of the housing of printer A. Cylinder 80 has a retractable rod 84 which extends through guide 86 on the lower section of bracket 82 . The enlarged end 88 of rod 84 engages plate D and moves plate D (along with the tag B supported by the plate and the article beneath the plate) from its first position (shown in solid) to its second position (shown in phantom) as the rod extends such that the tag and article are simultaneously penetrated by the needle.

As seen in FIG. 3 , base 38 carries a pair of pushbuttons 87 , 89 on either side. Both pushbuttons 87 , 89 must be depressed simultaneously to actuate cylinder 80 to extend rod 84 . Requiring both pushbuttons to be depressed simultaneously insures that the operator's hands are out of the way before cylinder 80 is actuated.

Since article E is situated below plate D, as plate D and the tag supported by it are moved by cylinder 80 toward second position, needle 22 penetrates article E and passes through hole 54 on the tag B supported by plate D at the same time. As plate D approaches the second position, switch 68 actuates attacher C to dispense a fastener and cause cylinder 80 to retract rod 84 , allowing springs 66 to move plate D back toward its first position and the operator to pull the tagged article away from the apparatus, severing the connecting elements between the anchored tag and the next tag in sequence.

As plate D approaches its first position, the actuator of a switch 90 , located on the front surface 17 of printer A, is tripped. Switch 90 actuates printer A to print and dispense the next tag B to plate D.

Whether the article is situated over plate D, as in the embodiment of FIG. 1 or under the plate, as in the embodiment of FIG. 2 , it is important that it be held taught when it is penetrated by the needle. This can be accomplished simply by having the operator hold the ends of article in his or her hands, one on either side of plate D, with the hands spread apart. However, FIGS. 5 and 6 illustrate a first mechanism to assist in stretching the article over the feed plate.

As seen in those figures, parts 92 and 94 pivotally mounted to opposite sides of base 38 can be used to stretch the article over recess 56 in base 38 . Parts 92 and 94 are spring-loaded toward base 38 by springs 96 mounted on shafts 98 which mount the parts to the base. The tops of shafts 98 are rotated outwardly and downwardly relative to base 38 , as seen in FIG. 6 .

The operator grasps the article at each side of base 38 , along with the underlying part 92 , 94 and then swings the parts outwardly and downwardly, such that the article is held taught above recess 56 in body 38 . With parts 92 , 94 in their remote position, plate D is moved toward its second position, such that the tag and article E are penetrated by the attacher needle.

A different mechanism for this purpose, usable with the second preferred embodiment, in which the article is located below plate D, is shown in FIGS. 7 and 8 . This mechanism includes parts 100 , 102 fixed to either side of base 38 . Each part 100 , 102 includes an upstanding hollow protrusion 104 , 106 , respectively.

A part 108 is mounted on attacher C by a bracket 110 . Part 108 carries two protrusions 112 , 114 , one on either side of needle 22 , which align with the recesses in protrusions 104 , 106 , respectively. As plate D is moved downwardly toward the needle, article E is also pushed downwardly and engaged by the tips of protrusions 112 , 114 . As the plate moves further, protrusions 112 and 114 , with the aligned sections of article E, are received in the recesses of protrusions 104 and 106 , respectively, stretching article E and holding it taught as it is penetrated by the needle.

It will now be appreciated that the present invention relates to apparatus for automatically attaching tags to articles which employs a simplified tag feed mechanism in the form of a pivotally mounted spring-loaded tag feed plate. The plate receives the printed tag from the tag dispenser. The plate, with its tag, and the article to be tagged, are moved together, either manually or by action of a pneumatic cylinder, toward an attaching device such that the needle penetrates the article and the tag at the same time. The attacher is actuated to dispense a fastener through the needle. The spring-loading of the plate then urges the plate away from the needle, allowing the article with its anchored tag to be removed, once the plate clears the needle. The tag dispenser is then actuated to dispense the next printed tag.

While only a limited number of preferred embodiments of the invention have been disclosed for purposes of illustration, it is obvious that many variations and modifications could be made thereto. It is intended to cover all of these variations and modifications which fall within the scope of the invention, as defined by the following claims.
