DETAILED DESCRIPTION OF THE INVENTION

Summarizing briefly in advance, the banding fixture 10 is for applying bands 11 to a workpiece such as a coil 12 of tubing or any other type of coiled material or material to be banded. The bands 11 are received in a predetermined length from a band-dispensing machine of any type which can supply it. Each band, by the use of fixture 10 , can then be banded about the coiled material.

The banding fixture 10 includes a body 14 fabricated out of a suitable plastic material. Body 14 includes a lower plastic portion 15 ( FIG. 2A ) of substantially rectangular configuration. Formed integrally with lower portion 15 are two narrow members 17 and 19 . Member 17 merges into a horizontal member 20 and member 19 merges into a horizontal member 21 . A horizontal opening 22 ( FIGS. 2 and 2A ) is defined by edge 23 ( FIG. 2A ) of lower body member 15 , edge 24 of member 20 , edge 25 of member 17 , edge 26 of member 19 and edge 29 ′ of member 21 .

Metal plates 25 are screwed to body 14 by screws 27 . A substantially rectangular block 29 ( FIG. 2 ) is secured between plates 25 by screws 30 and by a plastic pin 31 . A plastic pin 32 also extends through plates 25 and body portion 20 . A band-receiving slot 33 is thus formed between block 29 and body portion 20 . A second block 34 is secured between plates 25 by screws 35 . A slot 37 is located between body portion 21 and block 34 .

A carriage 39 is positioned in horizontal opening 22 for sliding movement between its position shown in FIG. 2 and the position shown in FIGS. 7 and 8 . Carriage 39 ( FIGS. 2B and 2C ) is a plastic block of substantially solid rectangular configuration having a recess 40 therein. Also, a spring-biased ball 41 protrudes from the upper surface 42 of carriage 39 . The bottom surface 43 ( FIGS. 2B and 8 ) of carriage 39 slides on surface 23 of body 14 , and the top surfaces 45 and 42 ( FIG. 2B ) travel in close relationship to surfaces 24 and 29 ( FIG. 2A ) of body 14 . As can be seen from FIGS. 2 and 5 , the edges 28 of plates 25 which are adjacent to and surround horizontal opening 22 confine carriage 39 for rectilinear movement within horizontal opening 22 . A plate 47 ( FIG. 3 ) is secured to body 14 by screws 49 and plate 47 is for securing the fixture 14 to the band-dispensing machine 13 by screws 50 which pass through apertures 51 in plate 47 . A leg 52 extends downwardly from body 14 for supporting body 14 on a suitable surface. Also, a screw 53 is threaded into body 14 to support a plate 54 which is attached to the band-dispensing machine 13 .

In operation, a band 11 having a cohesive coating on its upper surface is dispensed from band-dispensing machine into band-receiving slots 37 and 33 and confined against lateral movement by plates 25 on opposite sides of slots 37 and 33 . The band 11 is dispensed to a position as shown in FIG. 5 wherein its central portion lies across workpiece-receiving slot 36 in body 14 above the recess 40 in carriage 39 . The band 11 is positioned so that after it has been banded about coil 12 , its ends will be in perfect overlying relationship as shown in FIG. 8 . The workpiece coil 12 is thereafter manually initially positioned in slot 38 between body members 29 and 34 over the central portion of band 11 , as shown in FIG. 5 , and moved downwardly with the adjacent central band portion of band 11 through slot 36 and into recess 40 of carriage 39 , as shown in FIG. 6 . Slots 36 and 38 , which extend transversely to band-receiving slots 37 and 33 , can be considered separately and jointly as a coil-receiving slot, and more broadly as workpiece-receiving slots. When the coil is in the recess 40 , portions of the central portion of band 11 will lie along the sides of the coil which are adjacent the lower side of the coil in the lowermost part of recess 40 (FIG. 6 ). Thereafter, the carriage 39 is manually moved to the position shown in FIG. 7 wherein the ends of band 11 are pressed together between spring-biased ball 41 and the undersurface 24 of member 20 so that the band 11 assumes the condition shown in FIG. 8 . During the movement of the carriage 39 into horizontal opening 22 to the position of FIG. 7 , a portion of the central portion of band 11 to the right of the coil 12 in FIG. 6 will be moved across the inner side of the coil, and the end portions of the band will be placed in overlapping pressed relationship. Thereafter, the carriage 39 is moved to the position of FIG. 9 whereupon the coil 12 can be withdrawn.

Because the band 11 which is used is of the cohesive type, the surfaces of the band which are pressed together will cohere to each other but the band itself will not adhere to anything else. Because the band 11 is confined against lateral movement in slots 37 and 33 by plates 25 during the banding process, the end portions of the band which cohere to each other will be in exact overlying relationship with all of their edges being perfectly aligned with each other. However, while the side edges of the band are in exact alignment because of the above-noted confinement against lateral movement in slots 37 and 33 , under certain circumstances the extreme outer edges on the ends may not be in alignment, depending on the initial placement of the band.

Slots 36 and 38 were designated above as workpiece-receiving slots. In this respect, while the workpiece which was illustrated is a coil 12 , it will be appreciated that the “workpiece-receiving slot” can receive a bundle of material which is not in coil form and a single object to which a band has to be applied.

In FIGS. 10-26 another banding fixture embodiment 60 is disclosed. Summarizing briefly in advance, the fixture 60 includes a plurality of features which do not exist in the embodiment 10 of FIGS. 1-9 . These features include structure for easily replacing carriages to accommodate different coil sizes. Also, this embodiment includes an adjustable band-receiving slot to accommodate bands having different curl characteristics. In addition, the embodiment of FIGS. 10-26 is more simplified than the embodiment of FIGS. 1-9 .

The banding fixture 60 includes a body portion 61 ( FIGS. 10 and 13 ) which is fabricated out of a suitable plastic material. Body portion 61 includes a lower body portion 62 ( FIG. 13 ) of substantially rectangular configuration. Formed integrally with lower body portion 62 is a narrow solid rectangular member 63 which merges into solid rectangular horizontal member 64 . The body also includes an upper body portion 65 ( FIG. 10 ) in the form of a substantially solid rectangular plastic block. Two metal plates 67 ( FIGS. 10 , 11 , 12 and 14 ) secure body portions 61 and 65 to each other. In this respect screws 69 extend through the apertures 68 in the lower portions of plates 67 and are received in bores 76 ( FIG. 13 ) in body portion 61 to fasten these parts together. Screws 70 extend through bores 71 in plates 67 and are received in block 65 to fasten block 65 in position. Screws 72 extend through bores 73 ( FIG. 13 ) in plates 67 to fasten the upper portions of plates 67 to portion 64 of body portion 61 .

A plate 85 ( FIGS. 10 , 11 and 12 ) is secured to body 61 by screws 87 , and screws 89 extend through apertures 90 in plate 85 to secure fixture 60 to band-dispensing machine 13 which will dispense measured lengths of cohesive tape to fixture 60 . A foot 91 is secured to the undersurface of lower body portion 62 to rest on a suitable surface. A bracket 92 is fastened to band-dispensing machine 13 by screw 93 and to body portion 61 by screw 94 .

A carriage 74 ( FIGS. 10 , 12 , 15 ) is movable in horizontal opening 75 . Carriage 74 is fabricated from a block of plastic, and it has a recess 76 therein. Carriage 74 also includes sides 74 ′ and ends 78 and 76 ′ and a bottom surface 79 ′ and top surfaces 73 ′ and 75 ′ on opposite sides of recess 76 . The horizontal opening 75 is defined by edge 77 of lower body portion 62 , edge 79 of upper body portion 65 , edge 80 ( FIG. 13 ) of lower body portion 61 and edge 81 of body portion 61 . The edge portions 82 of plates 67 extend above edge 77 of lower body portion 62 , and the edges 83 of plates 67 extend below the lower edge 79 of upper body portion 65 to thereby provide side portions of plates 67 which confine carriage 74 in horizontal opening 75 . Also, portions 84 of plates 67 confine the left end of carriage 74 therebetween when the carriage is in the position of FIGS. 10 and 22 , and the portions 85 ′ of plates 67 confine the right end of carriage 64 therebetween when the carriage is in the position of FIG. 25 . Carriage 74 also includes a spring-biased ball 95 which biases the carriage upwardly so that its upper surfaces 73 ′ and 75 ′ ( FIG. 15 ) will bear against undersurface 79 of body portion 65 and the undersurface 64 ′ of body portion 64 when the carriage is in the position of FIG. 10 and against the undersurface 79 when the carriage 74 is in the position of FIG. 25 .

In accordance with one aspect of the present invention, the fixture 60 has an improved band-receiving arrangement. One aspect of this arrangement is shown in FIGS. 10 and 22 - 26 . In this respect, the substantially solid rectangular block 97 has its right end ( FIGS. 10 and 11 ) secured to plates 67 by screws 99 . The screws 99 also pass through elongated slots 100 ( FIG. 14 ) in plates 67 . Thus, the right end of block 97 can be adjusted in the vertical direction. The left end of block 97 is secured to plates 67 by brackets 101 ( FIGS. 10 , 20 and 21 ). The lower ends of brackets 101 have apertures 102 therein. Screws 70 pass through apertures 102 and are received in block 65 . The upper ends of brackets 101 have apertures 103 therein. Screws 104 pass through apertures 103 and into block 97 . As can be seen from FIGS. 10 and 22 - 26 , a slot 105 is provided between blocks 65 and 97 which is in the shape of a wedge with the wide part 107 being the entry portion for band 109 . Thus, in the event that band 109 has a relatively large upward curl, it will be received within slot 105 in the manner depicted in FIGS. 22 and 23 .

In addition to the foregoing, it is to be noted from FIGS. 10 , 10 A and 22 - 26 that the tape 109 passes across the top 110 of horizontal member 64 and is restricted only by the upper portions 111 of plates 67 . In other words, there is no block above horizontal member 64 and therefore the leading edge of band 109 does not have to pass through a slot. It is merely guided by the upper portions 11 of plates 67 .

The slot between blocks 65 and 97 is adjustable from the position shown in FIG. 10 to the positions such as shown in FIGS. 18 and 19 . In this respect, in FIG. 18 the slot 105 a is shown in a condition in which it has been placed by adjusting the screws 99 and 104 in slots 100 and 112 , respectively. In FIG. 19 the slot 105 b is shown in an enlarged condition relative to slot 105 a by adjusting the screws 99 and 104 to different positions in slots 100 and 112 , respectively. Thus, as can be seen from a comparison of FIGS. 10 , 18 and 19 , the slots 105 , 105 a and 105 b can be adjusted to different sizes depending on the curl of the particular banding material which is being used.

The sequence of banding a coil 113 is shown in FIGS. 22-26 , and this sequence is similar to that described in detail above relative to FIGS. 5-9 . Briefly, the band 109 is shown moving to the right and being inserted into slot 105 in FIGS. 22 and 23 . Slot 105 is located between the lower wall (not numbered) of block 97 and the upper wall (not numbered) of block 65 . Thereafter, as shown in FIG. 23 , coil 113 is inserted through slot 114 between the inner edges 115 and 117 of plates 67 and into engagement with the central portion of band 109 . Thereafter the coil 113 is moved downwardly through the slot portion 119 between the ends 120 and 121 of block 65 and member 64 , respectively. The coil 13 is then inserted into carriage recess 76 , as shown in FIG. 24 . The carriage 74 is then moved from the position of FIG. 24 to the position of FIG. 25 so as to cause the ends of band 109 to overlie each other and be pressed together because of the engagement between upper surface 73 ′ of carriage 74 and the undersurface 79 of block 65 , with the two surfaces being biased toward each other by the action of spring-biased detent 95 bearing on surface 77 of lower body portion 62 . Thereafter, the carriage is moved back to the position of FIG. 26 , and the banded coil 113 is removed from the fixture.

In accordance with another aspect of the present invention, carriages having different recess configurations can be used in fixture 60 . In this respect, a carriage having a recess configuration 76 is shown in FIG. 15. A carriage 74 a is shown in FIG. 16 having a recess 76 a which differs dimensionally from recess 76 . All other dimensions may be the same except for the upper surfaces 73 a and 75 a which correspond to upper surfaces 73 ′ and 75 ′. In order to remove carriage 74 from fixture 60 , it is merely necessary to unscrew screw 123 ( FIGS. 10 and 11 ) so as to pivot plate 124 from its obstructing orientation relative to window 125 ( FIG. 11 ) to thereby permit carriage 74 to be slid out of the fixture through the window 125 . Thereafter, a carriage, such as 74 a of FIG. 16 , can be slid into horizontal opening 75 through window 125 and thereafter plate 124 can be returned to its obstructing position relative to window 125 . The window 125 is bounded by the inside surfaces of plate portions 85 ′ and by surface 79 of block 65 and surface 77 of body portion 61 .

While preferred embodiments of the present invention have been disclosed, it will be appreciated that the present invention is not limited thereto but may be otherwise embodied within the scope of the following claims.
