Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to the field of manufacturing preassembled tape strips. More particularly, the present invention relates to manufacturing tape strips of a predetermined length, which are at one end folded about an aperture of a workpiece.




2. Description of the Prior Art




In the manufacture and assembly of fastening products, such as tape strips, belts and straps, there is commonly a need for the attachment of additional workpieces in order to provide a finished product. These additional devices may include, for example, rings, buckles or notions which allow for the tape strips, belts or straps to be attached or connected in some fashion.




Currently, the preferred method of attaching these buckles or notions to, for example, a tape strip, has been through sewing. In the conventional art, a tape strip is commonly folded about a workpiece and sewn to itself to create a strap that has the workpiece at one end. The other end of the strap is either sewn into a final product or connected in a similar fashion to another workpiece such as a buckle. These straps are used as part of backpacks, bags, luggage, life vests, etc. Various methods are used in the art to partially assemble a tape strip about a connecting device. These methods involve gluing or spot welding the strap to itself once the strap is folded about the connecting device. The partially assembled straps are then sent to a final sewing stage and incorporated into a final product.




U.S. Pat. No. 5,795,434 discusses the problems associated with assembling these tape strips in the prior art. In particular, the prior art describes methods for producing tape strips folded about a ring. The article described is manufactured by severing a predetermined length off a continuous tape, inserting the thus obtained tape strip through the ring, and folding the tape strip through and about the ring outwardly. In order to facilitate a subsequent sewing work, a laminate portion of the folded tape strip is provisionally secured, by hand, with a thread, a staple or any other fastener to keep the tape strip in a folded form. According to the conventional technology, however, production of the tape strip folded about the ring chiefly relies on manual work and hence needs large manpower, which would be inefficient and would thus render the finished product more expensive to produce. Further, since the thread and/or staple used in temporarily securing the folded tape strip are unnecessary in a final product, such a fastener has to be removed from the folded tape strip by hand at the final stage of production. When the final product is included in articles for human use, such as trampolines, the need for the removal of staples becomes especially important. If, through human error, a staple is not removed, its inclusion in the article may easily cause injury to the consumer.




U.S. Pat. No. 5,795,434 solves the problem of the prior art by providing a machine and method for continuously manufacturing a tape strip folded about a ring. Tape drawer rollers are intermittently driven and a continuous tape is intermittently fed along a tape traveling path. A leading edge portion of the tape is inserted through a ring at a tape folding section. After the tape is fed a predetermined length through the ring, the tape is stopped and then the lower end portion of the tape inserted through the ring is bent about the ring by a first bending member. A cutting device then severs a predetermined length of tape strip off the continuous tape, whereupon the an upper half of the severed tape strip is bent about the ring by a second bending member, thus providing a folded tape strip having a laminate portion. Finally the folded tape strip is discharged out of a machine after part of its laminate portion is fused by a fusing device. The product which is created by this method provides a tape which is folded equally about a ring. This product is used as connection points on a trampoline.




However, there is still a need in the art to provide for a machine which continuously manufactures a tape strip folded about a connecting device wherein an additional length of tape extends beyond the tape which is folded about the connecting device. There is a further need for a machine capable of properly manipulating a tape strip to allow differing lengths of tape to extend beyond the tape which is folded about the connecting device. The product formed from this process can then be used in a large number of applications, such as backpacks, bags, luggage, life vests, and other uses which require tape strips attached to connecting devices.




SUMMARY OF THE INVENTION




It is therefore an object of the present invention to provide for an efficient method of producing a tape strip folded about a connecting device which has an additional length of tape extending beyond the tape which is folded about the connecting device.




It is a further object of the present invention to improve the efficiency of production of tape strips folded about a connecting device so that production of a final product using such folded tape strips can be facilitated.




It is another object of the present invention to manufacture a tape strip folded about a connecting device which has an additional length of tape extending beyond the tape which is folded about the connecting device.




It is yet a further object of the present invention to provide an improved method of properly manipulating a tape strip to allow differing lengths of tape to extend beyond a tape which is folded about a connecting device.




Objects of the invention are achieved by providing a machine for continuously manufacturing tape strips having at least at one end a portion folded through an aperture of a workpiece. The machine includes a tape supply section which accommodates a supply of tape having an indeterminate length. The tape supply section supplies tape to a tape feed unit which is adapted to intermittently supply a first predetermined length of tape and a second predetermined length of tape in a two stage operation. Work pieces are supplied to and received by a workpiece receiving device adapted to hold the workpiece and position the aperture of the workpiece in the tape traveling path. First and second tape folders are oppositely positioned on each side of the workpiece receiving device. These tape folders operate to move in and out of the tape traveling path. A tape fusing member is positioned above the workpiece receiving device and the tape traveling path. The tape feed unit supplies a first predetermined length of tape through the aperture of a workpiece along the tape traveling path. The tape feed unit then supplies a second predetermined length of tape that does not go through the aperture of the workpiece. First and second tape folders then move from their position outside of the tape traveling path to a position in the tape traveling path causing the tape to fold toward the heated tape fusing member above the workpiece receiving device.




The foregoing is illustrative of the objects and features of the present invention and is not intended to be exhaustive or limiting of the possible advantages that can be realized or achieved. These and other objects and advantages of the present invention will be readily apparent to those skilled in the art from the following description.

; a workpiece gripper


200


which rotates from a position for receiving a workpiece from the workpiece supply path


100


to an upright position for holding a workpiece in a working position; a tape feed transfer unit


300


, which moves from a position distant to a workpiece gripper


200


to a position near the workpiece gripper


200


; a tape cutter


400


; a tape gripping assembly


500


; and a tape fusing member


600


.





FIGS. 2 and 3

illustrate a workpiece supply path


100


and a workpiece gripper


200


, in further detail. Workpiece supply path


100


includes a workpiece track


102


, which provides for the delivery of only one workpiece, such as a buckle (not shown), at a time. Buckles originate from an automated workpiece supply


104


or are fed manually onto the workpiece track


102


. Buckles may then move down the workpiece track


102


and stop at a position above an upper stopper


106


. The upper stopper


106


includes an upper actuator


108


and an upper gate


110


. The upper actuator


108


moves the upper gate


110


from a closed position to an open position. When the upper gate


110


is open, buckles can move past the upper stopper


106


. Buckles, or similar workpieces, may then move down the workpiece track


102


past the upper stopper


106


and stop at a lower stopper


114


. The lower stopper


114


includes a lower actuator


116


and a lower gate


118


. The lower actuator


116


moves the lower gate


118


from a closed position to an open position. When the lower gate


118


is open, a predetermined number of workpieces, such as buckles can move past the lower stopper


114


. The distance between the lower stopper


114


and the upper stopper


106


is preferably equal to the length of the predetermined number of workpieces utilized.




The lower stopper


114


and the upper stopper


106


open and close in an alternating fashion, thereby allowing the insertion of a predetermined number of workpieces per opening and closing cycle. The workpiece travels along the workpiece track


102


and stops at the upper stopper


106


. The upper gate


110


then opens, allowing workpieces to travel past the upper stopper


106


and stop at the lower stopper


114


. The upper gate


110


then closes, stopping any additional workpieces from passing the upper stopper


106


. Now, at least one workpiece, such as a buckle, rests between the upper stopper


106


and the lower stopper


114


. The lower stopper


114


then actuates and raises the lower gate


118


allowing at least one workpiece into the workpiece gripper


200


. The lower stopper


114


then actuates and lowers the lower gate


118


.

202


then rotates the workpiece receiver


204


and the workpiece to a vertical position. The workpiece gripper


200


also includes a first tape folder


206


, a second tape folder


208


and actuators


210

General Machine Operation




In one embodiment of the present invention and illustrated by

FIG. 9

, a workpiece


112


travels along a workpiece supply path


100


along a workpiece track


102


. Workpiece


112


can be automatically fed to the workpiece track


102


by a workpiece supply


104


or manually by an operator. The workpiece


112


first reaches an upper stopper


106


and stops. The upper stopper


106


then allows the workpiece


112


to pass, then shuts again. The workpiece


112


stops at a lower stopper


114


and rests between the lower stopper


114


and the upper stopper


106


. The lower stopper


114


then opens and allows the workpiece


112


to slide into the workpiece receiver


204


of the workpiece gripper


200


.




As illustrated in

FIGS. 9 and 10

, a rotator section


202


of the workpiece gripper


200


rotates so that the workpiece


112


, now in the workpiece receiver


204


is vertical. The tape feed transfer unit


300


moves to a position near the workpiece gripper


200


. This facilitates the transfer of tape


800


through the workpiece aperture


112




a


. Feed rollers


304


feed a predetermined amount of tape


800


through an aperture


112




a


of the workpiece


112


along a tape traveling path


310


. The amount of tape


800


fed through the aperture


112




a


depends on how much folded tape


800


is required and how far the tape feed transfer unit


300


will move away from the workpiece gripper


200


. As illustrated in

FIG. 11

, the tape feed transfer unit


300


then moves away from the workpiece gripper


200


. A tape feed guide actuator


308


forces the tape feed guide


306


into the tape traveling path


310


. This forces tape


800


to point in a downward direction. Feed rollers


304


then feed an additional predetermined length of tape


800


which collects in an opening between the tape feed transfer unit


300


and the workpiece gripper


200


. This will provide for an additional length of tape


800


which will extend away from the workpiece


112


. The tape cutter


400


will then sever the tape


800


as illustrated in FIG.


16


.




As illustrated in

FIGS. 11 and 12

, before the tape feed transfer unit


300


feeds an additional predetermined length of tape


800


, the first tape folder


206


and the second tape folder


208


move to the protracted position, forcing the tape


800


to fold about the workpiece


112


. As illustrated in

FIG. 12

, the tape fusing member


600


lowers a heating element


604


to a point directly above the workpiece


112


. The first tape gripper arm


504


extends and opposing members


508


and


510


grip a portion of tape


800


through the first tape folder


206


and the second tape folder


208


. At that time, the heating element


604


is located directly between the first tape folder slot


212


and the second tape folder slot


214


. Opposing members


508


and


510


then press the tape


800


into the heating element


604


of the tape fusing member


600


. Opposing members


508


and


510


then release the tape


800


and the first tape folder


206


and the second tape folder


208


retract. Opposing members


508


and


510


then grip a portion of the tape


800


above the workpiece


112


. At this point, the first tape folder


206


and the second tape folder


208


are in a retracted position. This is illustrated in FIG.


14


.




As illustrated in

FIGS. 15 and 16

, the first tape gripper arm


504


now has a welded portion of tape


800


and can then extend upward along arrow


504




b


and raise the tape


800


and the workpiece


112


out of the workpiece receiver


204


. The second tape gripper arm


506


may then extend along arrow


506




a


and opposing members


512


and


514


grip a portion of the tape


800


near the tape cutter


400


.




Now, the second tape gripper arm


506


holds a portion of the tape


800


near the tape cutter


400


. The tape gripping assembly


500


then rotates and ejects the completed workpiece


900


from the machine.




The completed strap


900


is shown in FIG.


17


. The completed strap


900


includes a predetermined length of tape


800


, part of which is folded and spot-welded


802


about an aperture


112




a


of the workpiece


112


. These completed workpieces


900


can now be used in completing a final product such as backpacks, bags, luggage, life vests, etc.
