  • ABSTRACT A method for ultrasonically splicing ribbonswhich 22 Claims, 5 Drawing Figures l ULTRAsoNIc RIBBON SPLICER BACKGROUND OF THE INVENTION l.
  • This invention relates to a method and apparatus for splicing ribbons, and more particularly, to methods of ultrasonically vibrating segments of ribbons together to heat fuse the ribbons.
  • the present invention sets forth a method for ultrasonically splicing ribbons which consists of placing the segments of ribbon to be spliced in a fixture to hold the segments in proper position for maximum splice strength, tensioning at least one of the ribbon segments, then actuating an ultrasonic welding device to produce relative motion between the ribbon segments to fuse the segments.
  • Welding of the ribbon segments is accomplished by means of apparatus in which the ribbon segments to be spliced are placed. Pressure means bear against the positioned ribbon segments to fix the position of the ribbon segments and tension at least one of the segments by forcing the segment into a cavity in the apparatus, thereby tensioning the ribbon for ultrasonic welding.
  • the present invention sets forth an apparatus for welding heat fusible ribbons which enables the layers of ribbon'which are to be welded to be positioned with respect to the welding implement and then selectively tensioned to provide optimum welding results.
  • Another object of the present invention is to provide an apparatus for ultrasonically welding heat fusible ribbons, which enables accurate alignment of the layers of ribbon to be welded to assure the optimum splicing angle of the ribbon.
  • Yet another object of the present invention is to provide an apparatus for ultrasonically welding heat fusible ribbons, which is able to maximize the rubbing motion between the segments of ribbon to be welded.
  • Still another object of the present invention is to provide an apparatus for ultrasonically welding heat fusible ribbons, which is of simplified construction, reliable in operation, and inexpensive to fabricate.
  • An additional object of the present invention is to provide an apparatus for ultrasonically welding ⁇ heat fusible ribbons, which provides means for isolating the holding mechanisms for the segments of ribbon to be welded from any vibrations transmitted by the ultrasonic welding implement.
  • Another object of the present invention is to provide a method for ultrasonically welding ribbon segments
  • Yet another object of the present invention is to provide a method for ultrasonically welding ribbon segments, which reduces the unfavorable frictional effects between the segments of ribbon to be welded.
  • Still another object of the present invention is to provide a method for ultrasonically welding ribbon segments, which is relatively simple, effective, and uncomplicated.
  • FIG. l is a perspective view showing an ultrasonic ribbon splicer built in accordance with the teachings of the present invention and a coacting ultrasonic unit.
  • FIG. 2 is a perspective view, partially in section, showing the ultrasonic implement in coacting relationship to the splicing mechanism.
  • FIG. 3 is a sectional view, showing the relationship of the ultrasonic implement, ribbon tension fixture, and ribbon segments, just prior to splicing.
  • FIG. 4 is a plan view of the ribbon segments just after splicing.
  • FIG. 5 is an exploded perspective view, partly in section, of an embodiment of a pressure leg adaptable for use in the ultrasonic ribbon splicer shown in FIG. l.
  • a ribbon splicing apparatus As shown in FIGS. 1 through S, a ribbon splicing apparatus, generally indicated at l0, consists of a locating bed member l2 and an upper plate 14 connected to an ultrasonic welding unit 16 by a bolt 18 which is locked to upper plate I4 by means of one or more locking nuts 20 and is connected to the ultrasonic unit 16 by conventional fastening means (not shown).
  • the ultrasonic welding unit 16 is a standard, cornmercially available device, such as the Branson 400 Series Ultrasonic Plastic Welder. It includes an acoustical horn 24 having a blade shaped end portion 26 which extends from a movable carriage 22 which can be raised or lowered by appropriate positioning means (not shown).
  • the acoustical horn is caused to vibrate in the range of 20,000 cycles per second.
  • the vibrations will pass from the horn into the plastic and travel until they meet the abutting surfaces.
  • the intense vibration of one surface moving against the other at ultrasonic frequencies causes sufficient buildup of heat through friction to melt the plastic and create a weld.
  • the upper plate 14 of the ribbon tensioning fixture l5 is connected to a locating bed 12 by aligning means consisting of'guides 28 and 30 connected to the upper plate by means of locking nuts 32 and 34.
  • the guides 28 and 30 aligns the ribbon tension fixture with the locating bed and maintains a parallel relationship between the upper plate 14 and the locating bed l2 during the splicing operation.
  • the connection of the upper plate 14 to both the carriage 22 of the ultrasonic unit, by means of connecting bolt 18, and the locating bed 12, by means of guides 28 and 30, insures that the upper plate 14 of the ribbon tension fixture is positioned with relation to the locating bed in accordance with the positioning of the ultrasonic welding horn.
  • the upper plate 14 vof the ribbon tensioning fixture consists of two shoulder portions 38 and 40 connected by a narrow neck portion 36 which is cut out to allow clearance for the ultrasonic horn 24.
  • Each shoulder portion has a plurality of pressure legs 42 extending downward to coact with appropriate forms in the locating bed which will be explained below.
  • the locating bed 12 is adapted to be fastened to a fixed immovable surface by means of bolts 44 and 46 and lock washer 48 and 50, or any other standard, convenient fastening means.
  • a pad (not shown) can be placed between the bottom of the locating bed 12 and the fixed immovable surface to which it is fastened to further insure that no sympathetic vibrations from the acoustic horn 24 will be transferred to the locating bed.
  • a plurality of ribbon positioning grooves 52 are formed in the upper surface of locating bed 12. These grooves are in an X-shaped pattern or mirror imaged V patterns which converge on a well or depression 54 in the central portion of the locating bed. An anvil plate 56 is secured in the well 54 by means of screws 58 or any other convenient fastening means.
  • the anvil plate includes an anvil 60 which bisects the angle of intersection of the ribbon positioning grooves 52.
  • the upper flat surface of the anvil 60 is adapted to coact with the bottom flat surface of the blade portion 26 of acoustic horn 24, as will be described below, during the process of splicing the ribbons.
  • Each of the ribbon positioning grooves 52 has a depression or enlarged circular area 62 adapted to coact with ribbon positioning pads 64 connected to the outwardmost pressure legs 42 on each shoulder. Further, each ribbon positioning groove 52 has a cavity 66 adapted to coact with the tension foot 68 which is positioned directly above the cavity and connected to each of the inner pressure legs 42 on each of the shoulders.
  • the ribbon positioning pads 64 will be pressing downward on the ribbon segments to hold them in the ribbon positioning groove 52 and, at the same time, the ribbon tensioning feet 68 will force a portion of the ribbon down into the tensioning cavities 66, thereby stretching the ribbon segment between the tensioning feet to hold it immobile for proper welding from the acoustical horn 24.
  • the tensioning feet 68 will force a small quantity of the ribbon down into the coacting tensioning feet cavities 66 to tension the ribbon to the predetermined tension. Then, only after the ribbon has been stretched into the tension feet cavities will the horn be brought to its full downward travel to place it in proper relationship to the ribbon and anvil for ultrasonic welding.
  • each of the pressure legs consist of a center post 74 movable vertically within a tubular member 76 and biased downward by means of spring 78.
  • the center post 74 has an enlarged head 76 which seats against an end wall 77 in the tubular member 76.
  • the appropriate pressure pad 64 or tensioning foot 68 will be connected to the movable center post 74 depending upon the function of the particular pressure leg.
  • the pressure pad 64 is connected to the center post 74 by screw threads.
  • the pressure legs are bolted directly to the upper plate 14 and held in position by means of conventional threaded fastening means 80 extending through a collar 82.
  • the pressure leg apparatus 42 shown in FIG. 5, Venables the force exerted by the spring 78 of the pressure leg to be adjusted. This adjustment is provided by means of an adjusting screw 84 threadably engaging the upper portion of the tubular member 76 for compressing the spring 78 between the screw 84 and the enlarged head 75 of the center-post 74 at varying amounts.
  • the pressure legs 42 for the tensioning feet 68 have a pin 87 extending transversely from the center post 74 through an elongated slot 88 in the tubular member 76. This pin and slot arrangement retains the tensioned foot 68 in a predetermined alignment with the cavities 66.
  • the separate segments 70 and 72 are placed in the aligned ribbon positioning grooves 52 of locating bed 12 so that they cross at an angle over the anvil 60. lt has been found through experimentation that the most satisfactory angle for optimum splicing results is approximately 30. However, many other angles can also be used to achieve satisfactory splicing results.
  • the carriage 22 for the acoustical horn 24 is started downward in its pathof travel towards the locating bed.
  • the plate 14 connected to the carriage will move downward so that the pairs of diagonally opposing ribbon positioning pads 64 will coact with their mating enlargements 62 in the ribbon positioning groove directly below them to hold each of the ribbon segments in proper relative position within the ribbon positioning grooves.
  • FIG. l shows the apparatus set up to use all four tensioning feet, the splicing process can be carried on with less than all of the tensioning feet in use. So, for example, it may be desirable to tension only one of the two ribbon segments, depending upon the characteristics of the ribbon. or possibly to tension one or both of the ribbon segments by use of only one of the diagonally opposed pairs of tensioning feet.
  • the acoustical horn continues downward on its path of travel until it comes to the position in which the tip of blade 26 will press the overlapping ribbon segments 70 and 72 against the top surface of the anvil 60 when the acoustical horn is actuated.
  • the oscillations or highspeed ultrasonic vibrations of the horn are imparted to the tensioned ribbon segments 7l]l and 72 causing frictional heat by the rubbing together of the two segments, which heat is sufficient to :melt the thermoplastic material from which the ribbon segments are made, thereby fusing the segments of the ribbon together.
  • the force of the acoustical horn bearing the ribbon segments downward against the anvil is sufficient to sever the fused ribbon segments into two separate symmetrical, V-shaped segments 7() and 72, as shown in FIG. 4.
  • the segments 70, 72 are unfolded, so that the final ribbon will be'perfectly straight, having a splice of approximately il5 from the parallel sides of the ribbon.
  • the fusing or melting of the ribbon segments during the splicing operation occurs only in a very isolated area as, for example, line 86 shown in FIG. 4.
  • the heat produced by the friction between the two ribbon segments is isolated to prevent it from spreading to surrounding areas of the ribbon segments by the anvil 60, which acts as a heat sink to draw off much of the excess heat produced during the splicing operation.
  • the ribbon segments and 72are spliced they will form a complete ribbon assembly which is in a folded condition, and which must be unfolded to form a straight or continuously dimensioned spliced or fused ribbon segment with the splice line at a 15 angle to the sides of the ribbon.
  • the ribbon segments to be fused must be placed in opposing relationship in the positioning bed, if itis desired to have surface continuity of the fused ribbon. For example, if only one side of each of the ribbon segments is coated with ink, the segments would have to be placed in the locating bed with the coated sides facing each other or away from each other.
  • the method of splicing the ribbons in the most-preferred embodiment calls for the tensioning of each ribbon segment at spaced points with a pair of coacting tensioning feet and tensioning cavities 68 and 66 respectively. It has been found that a predetermined tension of approximately 3-1/2 ounces applied to the ribbon by each tensioning foot and a predetermined ribbon splice angle of 15 produced highly desirable results of 5 to l0 pound weld strength. However, the amount of tension need not be restricted to 31/2 ounces, nor need .each ribbon segment be tensioned at two points. Further, it is possible to obtain improved splicing when only tensioning one of the two ribbon segments to be spliced.
  • the ribbon segments 70 and 72 could still be spliced by tensioning only the lower segment 70 with both of the tensioning feet 68. Although not as satisfactory as tensioning both segments at two points, this would still holdone of the ribbon segments to be spliced secure, so that the movement of the acoustical horn 26 would produce relative movement between the ribbon segments 70 and 72 which would be sufficient to raise the temperature of the ribbon segments above the melting temperature of V the ribbon material to produce the desired splice.
  • the tension applied to the ribbon segments can be adjusted by changing the extent of compression required by the pressure legs for travel of the upper plate 14 from the raised position to the lowered position. This adjustment in travel can be achieved by adjusting the connecting bolt 18 between the upper plate 14 and the carriage 22.
  • the connection between the upper ribbon tensioning fixture and the carriage of the ultrasonic welding unit enables the entire welding process to be done on a relatively automated basis.
  • the sequence of the various operations is set bythe relative heights of the ribbon positioning pads, ribbon tensioning feet, and blade portion of the acoustical horn, so that the various steps in the welding process must occur in the proper sequence. Once the pressures exerted by the individual pressure legs have been established and set, the alignment is kept constant, and very little adjustment is necessary.
  • bed means for said ribbon segments; means to position said ribbon segments on said bed means in proper relationship for splicing; means to tension said positioned ribbon segments when operatively engaged with said bedmeans; and means to move said ribbon tensioning means into and out of operative engagement with said bed means.
