FIELD OF THE INVENTION
ThiR invention relates to apparatus for positioning an article re]ative to an operative tool. In particular, this invention relates to the positioning of an article relative to the sewing needle of an automated sewing machine.

BACKGROUND OF TE~E INVF~NTION
The need to position an article rapidly and accurately with respect to an operative tool is a basic req~irement in much of today's automated machinery. The approaches which have been taken to accomplish this end have varied depending on the type of operative tool involved and the type of article which is to be positioned. For instance, in automated sewing the operative tool is usually a cyclically operated sewing needle which moves into and out of an article that is positioned thereunder. The article may be either a number of separate pieces of material that are 10 to be joined together or a separatc piece of material requiring a decorative pattern. In any event, the article is positioned relative to the sewing needle by a positioning apparatu~. This apparatus preferably moves the article only during that portion of the sewing cycle when the needle is withdrawn from the material. This places lS some rather stringent timing requirements on the positioning apparatus for high speed sewing. These stringent timing requirements usually include the need to quickly change the direction in which the article i9 being fed underneath the needle. Thi9 latter requirement i8 u6ually met by implementing two separate directional motions 20 which combine to define any particularly desired feed direction . for the next stitch, For instance, separate motiona in an X and Y direction within a cartesian coordinate system will accomplish such a feed direction capability. These separate motions are commonly referred to as occurring with respect to ~ and Y axes.
The need to simultaneously implement motion along two ~t ll~'i'~Z ~
separate axes at relatively higll speed has resulted in various types of positioning apparatus. These have included mechanisms which superimpose the motion occurring along one axis with respect to the moti.on occurring along the second axis. These mechanisms have by their very nature often been quite complex. These mechanisms S have moreover sometimes introduced undesirable vibrations into the overall positioning of the article relative to the sewing needle.
It is to be appreciated that while certain drawback~ have been herein discussed relative to positioning apparatus for sewing machines, the same considerations are also equally applicable 10 to certain other automatic machinery. To this extent, the invention which will be hereinafter described is also broadly applicable to automatic machinery in general.
1137~7 OBJECTS OF THE INVENTION
It i8 an object of this invention to provide an improved system for positioning an article relative to an operative tool.
It is another object of this invention to provide an improved system for rapidly positioning an article relative to an operative 5 tool during b~ief pe~iods of time that are dictated by the operation of the tool.
It i8 a s'dll further object of this invention to provide a positioning system which allows for accurate high speed sewing by an automated sewing machine.
' 113~27 SUMMARY OF T E INVENTION
The above and other objects are achieved according to the present invention by providing a rigid, lightweight posi-tioning system. The positloning system includes a rigid, lightweight frame that is slidably mounted in a predefined plane. The frame is driven within the plane by a remotely located motor. A carriage is slidably mounted on the frame so as to move in a direction transverse to the direction of movement of the frame itself. This carriage is driven along its axis by a second remotely located motor. The overall arrangement of the elements within the positioning system is such as to mlnimize the introduction of vibration at the point of sewing.
According to a further broad aspect of the present invention there is provided in an automatic sewing machine wherein an article is intermittently positioned relative to a sewing needle, an apparatus for positioning the article and which comprises the frame which is mounted for movement in a predefined plane. A carriage is mounted for movement on the ~rame. Means, attached to the carriage, is provided for securely holding the article in the predefined plane of movement for the frame.

~1~'7b~Z7 DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Figure 1, a sewing machine 10 i8 generally illustrated in conjunction with certain positioning apparatus.
The positioning apparatus includes a clamp mechanism 12 which 5 holds an article 14 that i6 to be sequentially positioned underneath the needle of the sew~ng machine 10. The clamp mechanism 12 is preferably of the type disclosed in U. S. Patent 4,171,672 in the names of Dorosz et al, issued on October 23, 1979, and entitled "Apparatus for Holding Work in a Sewing Machine". The clamp mechanism i8 10 attached to an arm 16 which is in turn attached to a carriage 18. The carriage 18 is mounted for movement along the length of a cylindrical axis member 20.
Referring to Figure 2, the carriage 18 is illustrated in exploded fashion relative to the cylindrical axis member 20. The cylindrical 15 axis member 20 is seen to be attached to a beam 22 of an L-shaped lightweight frame comprising beam6 22 and 24. The L-shaped lightweight frame furthermore comprises a Y-shaped bracing member 26. Both the L-shape and the Y-shape are partially broken away in Figure 2. A more complete showing of the L-shape and 20 the Y-shape can be appreciated from a top view of the positioning apparatus as shown in Figure 5. The entire lightweight frame comprising beams 22 and 24 plus the Y-shaped bracing member 26 is preferably fabricated from a lightweight material such as aluminum .
The lightweight frame is mounted for movement along a . , . .
,.
.
`;~ 113~27 linear guide mcmber 28 which is in turn mounted to a base 30.
The base 30 is broken away in ~igure 2, but can be more fully appreciated by referring to Figure 1. It i~ to be noted that the base 30 is relatively massive and serves as an eventual common base for all positioning elements. Referring again to Figure 2, S the lightweight frame is seen to have further support mounting structure comprising a downwardly extending portion 31 of the beam 22. The downwardly extending portion 31 has a pair of cylindrical rollers 32 and 33 mounted thereon. The rollers 32 and 33 engage the top and bottom surfaces of a planar guide 34.
The planar guide 34 is at a height above the base 30 that is established by a pair of vertical supports 36 and 38. The resulting height that is established for the lightweight frame is such as to preferably define a particular plane of movement for the frame. This plane of movement i5 preferably orthogonal to the needle of the sewing 15 machine 10.
In accordance with the invention, the clamped article 14 lies in a plane passing through the central axis 21 of the cylindrical axis member 20 as well as through the central axis 29 of the linear guide member 28. This is accomplished structur~lly by attaching 20 the arm 16 to the carriage 18 in such a manner as to define a position for the clamping mechanism 12 which ultimately produces a clamped article 14 in a plane passing through the central axis 21 of the cylindrical axis member 20. The lightweight frame is moreover configured so as to place the central axis 29 of the linear guide 25 member 28 in thi~ same plane. This is accomplished structurally by oausing the center of the complementary interior guide surface within the beam 24 to be coplanar with the central axis 21 of the cylindrical axis member 20. In this manner, the clamped portion of the article to be sewn will always lie in the plane of the imparted X and Y movements which occur along the central axes of the 5 cylindrical axis member 20 and the linear guide 28.
The lightweight frame is moved along the guide member 28 and the planar guide 34 by virtue of a motor 40. The motor 40 is actually contained within appropriate housing 42 such as shown in Figure 1. The housing 42 is mounted to an elevated 10 base 44 which is in turn affixed to the base 30. The motor 40 has associated gearing 46 which drives a pinion 48 which in turn drives a rack 50. The rack 50 is maintained in engagement with the pinion 48 by a roller 52. One end of the rack 50 is connected to the beam 22 of the lightweight frame. In thi6 manner, the rotational 15 drive of the motor 40 is operative to ultimately displace the l;ghtweight frame .
Having cliscussed the overall movement of the lightweight frame, it i8 now appropriate to turn to the relative movement of the carriage 18. It will be remembered that the carriage 18 20 is mounted for movement along the cylindrica; axis member 20 which is in turn affixed to the beam 22 of the lightweight frame.
The carriage 18 is seen to include a rack 54 which normally engages a pinion 5B. The engagement of the rack 54 with the pinion 56 is normally maintained by a roller 57. The pinion gear 56 is driven 25 by 8 spline shaft 58 in a manner which will be described hereinafter.
-io-The spline shaft 58 is rotatably supported within a lower portion 60 of the beam 22. The spline shaft 58 i9 furthermore rotatably supported within a mounting 62 that is secured to the base 30.
Gearing 64 at the end of the spline shaft 58 i8 engagably driven by a motor 66. It is to be noted that the motor 66 i8 mounted in 5 a conventional manner to the massive base 30 so as to thereby minimize any motor vibration. It is thus to be appreciated that the rotational motion from the motor 66 is imparted to the spline 0haft 58 which ultimately produces a linear motion of the carriage 18 along the cylindrical axis 20.
IO Referring to Figure 3, the rotatable mounting of the spline shaft 58 within the lower portion 60 of the beam 22 is illustrated in detail. The lower portion 60 of the beam 22 is broken away so as to clearly show the rotational mounting of the shaft. The spline shaft 58 is seen to be suspended within a cylindrical collar 15 B8 by a plurality of ball bearings such as 70. This is more clearly illustrated in Figure 4 wherein a cross-sectional view of the spline ~haft 58 within the cylindrical collar 68 is generally shown.
The cylindrical collar 68 is seen to includc thrcc scparate recesses 72, 74 and 76, each of which has a paired set of ball bearings 20 such as 70 and 80. Each set of ball bearings is maintained within the respective recess by a retaining ring 82. The ~pline shaft 58 comprises three separate splines 84, 86, and 88 which are respectively supported by the paired sets of ball bearings. It is to be appreciated that a rotation of the spline shaft 58 will impart 25 a rotation to the cylindrical collar 58. As is partially illustrated ~ 7~;2'7 in Figure 4, the cylindrical collar 68 is keyed to a casing 90 via a keyway arrangement 92. The casing 90 i8 more fully depicted in Figure 3 and is seen to include the pinion gear 56 at its front end. The casing 90 and the pinion gear 56 will rotate with the cylindrical collar 68 when the same is rotatably driven by the spline shaft 58. The casing 90 will furthermore rotate relative to the lower portion 60 of the beam structure 22 by virtue of a pair of ball bearing mounts 94 and 96.
As has been previously described, the pinion gear 56 engages the rack 54 of the carriage 18. A rotation of the pinion gear 56 will move the rack 54 linearly so as to thereby move the carriage along the length of the cylindrical axis member 20. This movement of the carriage may be effected while the lightweight frame i8 also being displaced along the length of the rotating shaft 58.
Referring now to Figure 5, an overall top view of the positioning , IS apparatus i8 illustrated. The Y-shaped configuration of the brace structure 26 within the lightweight frame is particularly illustrated.
The relationship of the various positioning elements can also be appreciated. In this regard, the parallel re]ationship of the guide 28, the shaft 58, the support 34 and the rack 50 is readily apparent.
It is to be appreciated from the above, that a preferred embodiment of a lightweight, rigid and responsive positioning system has been disclosed. This system has been specifica]ly disclosed for use with a sewing machine although the system is equally applicable to other machinery. It is furthermore to be appreciated that alternative structures may be substituted for 1~7~3Z7 elements of the positioning sy6tem without departing frorn the ScGpe of the present invention.

~1~'7b~Z7 DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Figure 1, a sewing machine 10 i8 generally illustrated in conjunction with certain positioning apparatus.
The positioning apparatus includes a clamp mechanism 12 which 5 holds an article 14 that i6 to be sequentially positioned underneath the needle of the sew~ng machine 10. The clamp mechanism 12 is preferably of the type disclosed in U. S. Patent 4,171,672 in the names of Dorosz et al, issued on October 23, 1979, and entitled "Apparatus for Holding Work in a Sewing Machine". The clamp mechanism i8 10 attached to an arm 16 which is in turn attached to a carriage 18. The carriage 18 is mounted for movement along the length of a cylindrical axis member 20.
Referring to Figure 2, the carriage 18 is illustrated in exploded fashion relative to the cylindrical axis member 20. The cylindrical 15 axis member 20 is seen to be attached to a beam 22 of an L-shaped lightweight frame comprising beam6 22 and 24. The L-shaped lightweight frame furthermore comprises a Y-shaped bracing member 26. Both the L-shape and the Y-shape are partially broken away in Figure 2. A more complete showing of the L-shape and 20 the Y-shape can be appreciated from a top view of the positioning apparatus as shown in Figure 5. The entire lightweight frame comprising beams 22 and 24 plus the Y-shaped bracing member 26 is preferably fabricated from a lightweight material such as aluminum .
The lightweight frame is mounted for movement along a . , . .
,.
.
`;~ 113~27 linear guide mcmber 28 which is in turn mounted to a base 30.
The base 30 is broken away in ~igure 2, but can be more fully appreciated by referring to Figure 1. It i~ to be noted that the base 30 is relatively massive and serves as an eventual common base for all positioning elements. Referring again to Figure 2, S the lightweight frame is seen to have further support mounting structure comprising a downwardly extending portion 31 of the beam 22. The downwardly extending portion 31 has a pair of cylindrical rollers 32 and 33 mounted thereon. The rollers 32 and 33 engage the top and bottom surfaces of a planar guide 34.
The planar guide 34 is at a height above the base 30 that is established by a pair of vertical supports 36 and 38. The resulting height that is established for the lightweight frame is such as to preferably define a particular plane of movement for the frame. This plane of movement i5 preferably orthogonal to the needle of the sewing 15 machine 10.
In accordance with the invention, the clamped article 14 lies in a plane passing through the central axis 21 of the cylindrical axis member 20 as well as through the central axis 29 of the linear guide member 28. This is accomplished structur~lly by attaching 20 the arm 16 to the carriage 18 in such a manner as to define a position for the clamping mechanism 12 which ultimately produces a clamped article 14 in a plane passing through the central axis 21 of the cylindrical axis member 20. The lightweight frame is moreover configured so as to place the central axis 29 of the linear guide 25 member 28 in thi~ same plane. This is accomplished structurally by oausing the center of the complementary interior guide surface within the beam 24 to be coplanar with the central axis 21 of the cylindrical axis member 20. In this manner, the clamped portion of the article to be sewn will always lie in the plane of the imparted X and Y movements which occur along the central axes of the 5 cylindrical axis member 20 and the linear guide 28.
The lightweight frame is moved along the guide member 28 and the planar guide 34 by virtue of a motor 40. The motor 40 is actually contained within appropriate housing 42 such as shown in Figure 1. The housing 42 is mounted to an elevated 10 base 44 which is in turn affixed to the base 30. The motor 40 has associated gearing 46 which drives a pinion 48 which in turn drives a rack 50. The rack 50 is maintained in engagement with the pinion 48 by a roller 52. One end of the rack 50 is connected to the beam 22 of the lightweight frame. In thi6 manner, the rotational 15 drive of the motor 40 is operative to ultimately displace the l;ghtweight frame .
Having cliscussed the overall movement of the lightweight frame, it i8 now appropriate to turn to the relative movement of the carriage 18. It will be remembered that the carriage 18 20 is mounted for movement along the cylindrica; axis member 20 which is in turn affixed to the beam 22 of the lightweight frame.
The carriage 18 is seen to include a rack 54 which normally engages a pinion 5B. The engagement of the rack 54 with the pinion 56 is normally maintained by a roller 57. The pinion gear 56 is driven 25 by 8 spline shaft 58 in a manner which will be described hereinafter.
-io-The spline shaft 58 is rotatably supported within a lower portion 60 of the beam 22. The spline shaft 58 i9 furthermore rotatably supported within a mounting 62 that is secured to the base 30.
Gearing 64 at the end of the spline shaft 58 i8 engagably driven by a motor 66. It is to be noted that the motor 66 i8 mounted in 5 a conventional manner to the massive base 30 so as to thereby minimize any motor vibration. It is thus to be appreciated that the rotational motion from the motor 66 is imparted to the spline 0haft 58 which ultimately produces a linear motion of the carriage 18 along the cylindrical axis 20.
IO Referring to Figure 3, the rotatable mounting of the spline shaft 58 within the lower portion 60 of the beam 22 is illustrated in detail. The lower portion 60 of the beam 22 is broken away so as to clearly show the rotational mounting of the shaft. The spline shaft 58 is seen to be suspended within a cylindrical collar 15 B8 by a plurality of ball bearings such as 70. This is more clearly illustrated in Figure 4 wherein a cross-sectional view of the spline ~haft 58 within the cylindrical collar 68 is generally shown.
The cylindrical collar 68 is seen to includc thrcc scparate recesses 72, 74 and 76, each of which has a paired set of ball bearings 20 such as 70 and 80. Each set of ball bearings is maintained within the respective recess by a retaining ring 82. The ~pline shaft 58 comprises three separate splines 84, 86, and 88 which are respectively supported by the paired sets of ball bearings. It is to be appreciated that a rotation of the spline shaft 58 will impart 25 a rotation to the cylindrical collar 58. As is partially illustrated ~ 7~;2'7 in Figure 4, the cylindrical collar 68 is keyed to a casing 90 via a keyway arrangement 92. The casing 90 i8 more fully depicted in Figure 3 and is seen to include the pinion gear 56 at its front end. The casing 90 and the pinion gear 56 will rotate with the cylindrical collar 68 when the same is rotatably driven by the spline shaft 58. The casing 90 will furthermore rotate relative to the lower portion 60 of the beam structure 22 by virtue of a pair of ball bearing mounts 94 and 96.
As has been previously described, the pinion gear 56 engages the rack 54 of the carriage 18. A rotation of the pinion gear 56 will move the rack 54 linearly so as to thereby move the carriage along the length of the cylindrical axis member 20. This movement of the carriage may be effected while the lightweight frame i8 also being displaced along the length of the rotating shaft 58.
Referring now to Figure 5, an overall top view of the positioning , IS apparatus i8 illustrated. The Y-shaped configuration of the brace structure 26 within the lightweight frame is particularly illustrated.
The relationship of the various positioning elements can also be appreciated. In this regard, the parallel re]ationship of the guide 28, the shaft 58, the support 34 and the rack 50 is readily apparent.
It is to be appreciated from the above, that a preferred embodiment of a lightweight, rigid and responsive positioning system has been disclosed. This system has been specifica]ly disclosed for use with a sewing machine although the system is equally applicable to other machinery. It is furthermore to be appreciated that alternative structures may be substituted for 1~7~3Z7 elements of the positioning sy6tem without departing frorn the ScGpe of the present invention.
