Description
211886 ~
M~Tt'~ FOR 8BCURING O-RING8 TO CAP8 FIELD OF THE lNv~ lON
The present invention relates to a machine for securing O-rings to caps, either interiorly in cases where the cap has a bore, or exteriorly in cases where the cap has a neck portion.
BACKGROUND OF THE INVENTION
Present machines for inserting O-rings onto or into caps operate with pneumatic or hydraulic systems.
However, because it is difficult to achieve high synchronization of pistons used in such systems, the speed at which the process of placing O-rings on or in caps must be maintained at a relatively slow pace.
It is an object of the present invention to provide a machine which overcomes the above problems and which permits a much higher rate of ring installation.
This is achieved by providing a machine which is entirely mechanical, none of the components co-operating to install the O-rings into and onto the caps being pneumatically or hydraulically operated; hence, synchronization is much easier to obtain than that presently used.
2ll886l The present invention therefore relates to a machine for securing O-rings to caps which comprises:
a support structure;
a first station fixedly mounted to the support structure and including means for serially receiving and displacing caps to a first dispensing area and means for serially receiving and displacing O-rings to a second dispensing area;
a second station fixedly mounted to the support structure and spaced horizontally from the first station and including means for serially receiving and displacing caps having O-rings secured thereto;
a third station disposed between the first and second stations and being movable to and fro between the 5 first and second stations;
cap engaging means mounted on the movable station;
O-ring engaging means mounted on the movable station and disposed in vertical alignment with the cap 0 engaging means;
means on the movable station causing a vertical displacement of the cap engaging means and of the O-ring engaging means during a complete to and fro horizontal displacement of the movable station whereby the cap engaging means and the O-ring engaging means are caused to define a circular trajectory including a common tangential travel;
_ - 3 means for causing a transfer of an O-ring from the O-ring engaging means onto the cap during the tangential travel;
first holding means in the first dispensing area of the first station allowing the cap engaging means to engage a cap;
second holding means in the second dispensing area of the first station allowing the ring to be deposited on the O-ring engaging means; and means on the second station allowing a cap with O-ring thereon to be deposited in the receiving and dispensing means after the common tangential travel.
In one form of the invention, the O-rings engaging means are removably mounted from the movable station so that first and second embodiments may be used alternatively with the remaining components of the machine.
In the first embodiment, the O-ring engaging means are equipped with means for engaging interiorly the O-rings and stretching them outwardly so that they be fitted exteriorly onto a cap.
In the second embodiment of the invention, the O-rings engaging means are so constructed as to insert the O-ring interiorly within the bore of the cap.
21188~1 Other objects and further scope of applicability of the present invention will become apparent from the detailed description given hereinafter.
It should be understood, however, that this detailed S description, while indicating preferred embodiments of the invention, is given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art.

Referring to figures 1 and 2, the machine of the present invention, generally denoted 10, is supported on a frame 12 mounted on a base 14. The machine comprises three main stations, consisting of oppositely disposed stations 16 and 18 which are fixedly mounted to the frame 12 and a station 20 movably disposed between the two fixed stations 16 and 18. Upper and lower rods 22 and 24 are mounted to and horizontally extend between stations 16 and 18 allowing station 20 to move horizontally to and fro between stations 16 and 18.
Referring also to figure 3, the first fixed station 16 comprises an horizontally extending rail structure 17 which is adapted to receive and displace horizontally caps 26 onto which O-rings have been secured while the second fixed station 18 comprises upper and lower horizontal rail structures 28 and 30 which are adapted to respectively receive the caps 26 and the O-rings 32. Structures 16, 28 and 30 are not essential parts of the present invention; hence, a detailed description of their construction is not deemed necessary. The principal purpose of these rail structures is to channel caps, O-rings or caps with O-rings to a desired station, as may be seen in figure 4.
A pair of arms 34 and 36 pivotally mounted at 38 and 40, respectively, are used to allow or prevent the horizontal 2I1~86 ~
displacement of the caps 26 and the 0-rings 32 in the directions indicated by arrows 42 and 44, respectively.
As shown in figures 5 and 6, a pair of pivotally mounted cap retaining clamps 46 and 48 is displayed at the innermost end of the structure 28 while a pair of pivotally mounted 0-ring retaining clamps 50 and 52 is displayed at the innermost end of the rail structure 30. Clamps 46 and 48 pivot about respective hinge axes 54 and 56 while clamps 50 and 52 pivot about respective hinge axes 58 and 60. Also, seen in figure 6, clamps 46 and 48 include oppositely facing cap retaining seats 62 and 64 while clamps 50 and 52 include oppositely facing jaws 66 and 68 to hold an 0-ring 32. Clamps 46 and 48 further include rollers 70 and 72 which are adapted to rollingly contact a rod 74 forming part of a cap engaging means 75 which, in turn, forms part of the upper part of the movable station 20 (as detailed hereinbelow). Means, generally denoted 76, are mounted to the lower part of the movable station 20 to seize the 0-ring 32 from the clamps 50 and 52 (also as detailed hereinbelow).
Reverting to figures 3 and 4, the movable station 20 comprises a main chassis 78 with upper and lower horizontal extensions 80 and 82 in the direction of the fixed station 18. The chassis 78 displays a vertically extending slot 84 with opposite guide rails 86 ,- - 8 - 211~
and 88 in which is engaged a pair of roller guides 90 and 92 to which is secured vertical shaft 94, 96 respectively. These guides are and rotatably mounted to circular disks 98, 100 which, in turn, are rotatable about shafts 102, 104 respectively. These shafts are driven by a motor 106 (figure 1) via a belt 107 and a clutch device 108 (figure 2). As seen in figure 2, the two shafts 102 and 104 are interconnected by means of a pair of gears 110 and 112 which provide them with rotations of opposite direction as indicated by arrows 111 and 113 (see figure 3). The rotation of disks 98 and 100 causes the horizontal displacement of the movable station 20 (see arrow 114) as well as the vertical displacements of the shafts 94 and 96 (see arrows 95 and 97) as a result of the guide rollers 90 and 92 engaged in the guide rails 86 and 88.
Referring to the schematic representation of figure 9, the circular trajectories 111, 113 of guides 90 and 92 cause similar circular trajectories 154, 156 of the cap engaging means 75 and of the 0-ring engaging means 76; this is accomplished via a pair of links 116, 118 connecting the rods 94, 96 to the cap engaging means 75 and the 0-ring engaging means 76.
The machine illustrated in figures 1-10 is adapted for placing 0-rings onto the neck portion of a cap while figures 11-16 illustrate a second embodiment 2ll886~
whereby the machine is adapted for inserting an O-ring inside the neck portion of a cap. Both embodiments are achieved by simply replacing the 0-ring engaging means which differ from one embodiment to the other. However, in both embodiments, the cap is provided with a bore in its upper part so as to receive therein the lower end 166 of the rod 74.
Whenever it is wished to place an 0-ring onto the neck portion of a cap, the means 76, illustrated more particularly in figures 5-10, will be mounted to the movable station of the machine.
Referring to figure 5, means 76 comprise a sleeve member 130 in which is mounted a series of circumferentially spaced fingers 132, each pivotally mounted at 134. The upper extremity 136 of each finger is radially moved inwardly and outwardly as a result of the vertical displacement of the lower part of the finger within the bore of sleeve 130 which is shaped with sloping faces 142, the latter being contacted by the lower extremity 138 of the finger when vertically displaced by the central stem 140. Hence, where the upper extremities 136 are in their innermost radial position, they extend through the O-ring 32 and, as the extremities 138 contact the surfaces 142, they outwardly and radially stretch the 0-ring such as shown by the 2118g~ 1 dotted lines. Simultaneously, a series of circumferentially spaced elements 144 located between the finger extremities 136 contact the lower edge of the jaw portions 66 and 68 of the clamps causing them to pivot outwardly about axes 58 and 60. These jaw portions then remain in contact with the outside wall of the fingers such as shown in figure 6. In this latter figure, the finger extremities 136 are shown extending beyond the threaded neck portion 26a of the cap, but slightly lower than the lower edge of the cap head portion 26b.
Although not shown, springs are used to return the clamps 50 and 52 to their original position afterwards.
Referring to figures 7 and 8, the continuous upward movement of shaft 140 causes the raising of a series of the circumferentially spaced pushing elements 144 displacing the 0-ring 32 off the fingers 136 until it snaps into place under the cap head 26b.
As can be seen in figure 9, the circular trajectories of guides 90 and 92 in the directions indicated by arrows 111 and 113 are transmitted through links 116, 118 to the engaging means 75 and 76 as indicated by arrows 154, 156. Because of the vertical alignment of these engaging means, there is a common tangential trajectory. However, such trajectory is flattened to an horizontal line during the 0-ring transfer onto the cap; these horizontal trajectories are -- - 11- 2ll~8fi indicated by dotted line portions 158 and 160. Referring also to figure 10, this horizontal segment of each circular trajectory is permitted by the action of springs 162 and 164 which are compressed during this segmental travel. During the 0-ring transfer operation, a cap frictionally engaged to the extremity 166 of rod 74 will contact the upper extremity of the 0-ring engaging means 76 prior to the above mentioned tangential point; they remain in contact horizontally under the action of their respective springs 162, 164, which are compressed in a direction away from the contact point.
As can be seen in figure 10, the cap engaging means 75 comprise a holding member 168 secured to the link 116 and in which is housed the spring 162 acting on the vertically moving rod 74. Similarly, the 0-ring engaging means 76 includes the spring 164 which acts against the inner sleeve member 165 onto which are mounted the pushing elements 144.
Rod 74 is movable within the sleeve member 168 (as indicated by arrow 172 in figure 5) which, in turn, is movable vertically (as indicated by arrows 173 in figure 6). As the sleeve 168 is lowered, it contacts the guide rolls 70 and 72 causing the pivotal movement of the cap engaging clamps 46 and 48 about their pivot points 54 and 56. Although not shown, springs are used to return 211~g6~
the clamps 46 and 48 to return to their original position afterwards.
Figures 11-18 pertains to a machine according to the present invention when embodied to insert an O-ring within a cap. The entire machine described abovewith reference to figures 1-10 is not altered when embodying this second embodiment with the exception that the cap engaging means 76 of figures 1-10 are replaced by a modified cap engaging means, generally denoted 200.
10Referring to figure 11, the cap engaging means 200 comprise two separate parts: a funnel shaped member, generally denoted 202, and an O-ring engaging assembly 204. The cap 206 used with the present embodiment is constructed (see figure 13) with a lower inner threaded 15bore 206a and an upper bore 206b into which frictionally fits the lower extremity 166 of the vertical rod 74 of cap engaging means 75.
The funnel member 202 is supported on a bracket 208 secured by means of fastening elements 210, 212 to the chassis 78 of the movable station 20.
Referring to figures 13 and 14, the funnel 202 comprises a cylindrical portion 214, the inner bore of which has a portion defined by inwardly inclined faces 216, a top annular face 218 on which rests the lower -peripheral edge of the cap and a bottom face 219, the function of which will be described hereinbelow.
The 0-ring inserting means 204 is adapted to insert an O-ring 220 into the bore 206a of the cap.
Referring to figure 12, it comprises a hollow cylindrical part 222 having a series of upper extensions 224, 226, 228 and 230 projecting vertically from the upper edge 232 thereof. Within member 222, a cylindrical member 234 is vertically displaceable and includes, at its upper end, 10 a pair of half-cone shaped elements 236, 238. Between these elements 236 and 238 extends a rectangular plate member 240 which is vertically displaceable.
As can be seen in figures 12 and 16, plate 240 is slidably received within the cylindrical member 234 15 and between the cone-shaped elements 236 and 238. This plate may be pushed downwards at the level of the top face 234' of the cylindrical member 234 during the 0-ring transfer operation against the action of a spring 250 which has its lower end bearing against the vertical 20 support 252. This spring serves to return elements 236, 238 and 240 upwards after the O-ring transfer operation is completed.
Figures 12 and 14 illustrate the insertion of the 0-ring 220 within the bore 206a of the cap. The inner inclined faces 216 of the funnel member bend the 0-211~8~
ring in the shape illustrated in figure 12. As elements 226 and 230 reach inside the funnel member and contact the lower edges of the inner inclined walls 216, elements 224 and 228 continue upwards and penetrate slots (not shown) in walls 216. The cylindrical member 234 further continues upwards pushing the 0-ring by the upper edges of the inclined walls 216 to thereafter locate it properly against the top face 254 of the bore of the cap as illustrated in figure 11.
In figure 15, the dotted lines 256 indicate the circular trajectory of the 0-ring engaging means 204 as well as that of the funnel 202. As in the first embodiment illustrated in figures 1-11, there is also provided in this second embodiment a common tangential travel during which the cap transferring elements are maintained in a horizontal direction allowed by the action of spring 250.
For both embodiments illustrated in the drawings, the movable station 20, after the 0-ring transfer operation to the cap, moves towards an entry 260 (see figures 3 and 11) of the rail structure 16. These caps are moved horizontally until they drop into a collecting bin (not shown).
Although the invention has been described above in relation to two specific forms, it will be evident to 2~1~86~
.._ a person skilled in the art that it may be modified and refined in various ways. It is therefore wished to have it understood that the present invention should not be limited in scope, except by the terms of the following claims.

Referring to figures 1 and 2, the machine of the present invention, generally denoted 10, is supported on a frame 12 mounted on a base 14. The machine comprises three main stations, consisting of oppositely disposed stations 16 and 18 which are fixedly mounted to the frame 12 and a station 20 movably disposed between the two fixed stations 16 and 18. Upper and lower rods 22 and 24 are mounted to and horizontally extend between stations 16 and 18 allowing station 20 to move horizontally to and fro between stations 16 and 18.
Referring also to figure 3, the first fixed station 16 comprises an horizontally extending rail structure 17 which is adapted to receive and displace horizontally caps 26 onto which O-rings have been secured while the second fixed station 18 comprises upper and lower horizontal rail structures 28 and 30 which are adapted to respectively receive the caps 26 and the O-rings 32. Structures 16, 28 and 30 are not essential parts of the present invention; hence, a detailed description of their construction is not deemed necessary. The principal purpose of these rail structures is to channel caps, O-rings or caps with O-rings to a desired station, as may be seen in figure 4.
A pair of arms 34 and 36 pivotally mounted at 38 and 40, respectively, are used to allow or prevent the horizontal 2I1~86 ~
displacement of the caps 26 and the 0-rings 32 in the directions indicated by arrows 42 and 44, respectively.
As shown in figures 5 and 6, a pair of pivotally mounted cap retaining clamps 46 and 48 is displayed at the innermost end of the structure 28 while a pair of pivotally mounted 0-ring retaining clamps 50 and 52 is displayed at the innermost end of the rail structure 30. Clamps 46 and 48 pivot about respective hinge axes 54 and 56 while clamps 50 and 52 pivot about respective hinge axes 58 and 60. Also, seen in figure 6, clamps 46 and 48 include oppositely facing cap retaining seats 62 and 64 while clamps 50 and 52 include oppositely facing jaws 66 and 68 to hold an 0-ring 32. Clamps 46 and 48 further include rollers 70 and 72 which are adapted to rollingly contact a rod 74 forming part of a cap engaging means 75 which, in turn, forms part of the upper part of the movable station 20 (as detailed hereinbelow). Means, generally denoted 76, are mounted to the lower part of the movable station 20 to seize the 0-ring 32 from the clamps 50 and 52 (also as detailed hereinbelow).
Reverting to figures 3 and 4, the movable station 20 comprises a main chassis 78 with upper and lower horizontal extensions 80 and 82 in the direction of the fixed station 18. The chassis 78 displays a vertically extending slot 84 with opposite guide rails 86 ,- - 8 - 211~
and 88 in which is engaged a pair of roller guides 90 and 92 to which is secured vertical shaft 94, 96 respectively. These guides are and rotatably mounted to circular disks 98, 100 which, in turn, are rotatable about shafts 102, 104 respectively. These shafts are driven by a motor 106 (figure 1) via a belt 107 and a clutch device 108 (figure 2). As seen in figure 2, the two shafts 102 and 104 are interconnected by means of a pair of gears 110 and 112 which provide them with rotations of opposite direction as indicated by arrows 111 and 113 (see figure 3). The rotation of disks 98 and 100 causes the horizontal displacement of the movable station 20 (see arrow 114) as well as the vertical displacements of the shafts 94 and 96 (see arrows 95 and 97) as a result of the guide rollers 90 and 92 engaged in the guide rails 86 and 88.
Referring to the schematic representation of figure 9, the circular trajectories 111, 113 of guides 90 and 92 cause similar circular trajectories 154, 156 of the cap engaging means 75 and of the 0-ring engaging means 76; this is accomplished via a pair of links 116, 118 connecting the rods 94, 96 to the cap engaging means 75 and the 0-ring engaging means 76.
The machine illustrated in figures 1-10 is adapted for placing 0-rings onto the neck portion of a cap while figures 11-16 illustrate a second embodiment 2ll886~
whereby the machine is adapted for inserting an O-ring inside the neck portion of a cap. Both embodiments are achieved by simply replacing the 0-ring engaging means which differ from one embodiment to the other. However, in both embodiments, the cap is provided with a bore in its upper part so as to receive therein the lower end 166 of the rod 74.
Whenever it is wished to place an 0-ring onto the neck portion of a cap, the means 76, illustrated more particularly in figures 5-10, will be mounted to the movable station of the machine.
Referring to figure 5, means 76 comprise a sleeve member 130 in which is mounted a series of circumferentially spaced fingers 132, each pivotally mounted at 134. The upper extremity 136 of each finger is radially moved inwardly and outwardly as a result of the vertical displacement of the lower part of the finger within the bore of sleeve 130 which is shaped with sloping faces 142, the latter being contacted by the lower extremity 138 of the finger when vertically displaced by the central stem 140. Hence, where the upper extremities 136 are in their innermost radial position, they extend through the O-ring 32 and, as the extremities 138 contact the surfaces 142, they outwardly and radially stretch the 0-ring such as shown by the 2118g~ 1 dotted lines. Simultaneously, a series of circumferentially spaced elements 144 located between the finger extremities 136 contact the lower edge of the jaw portions 66 and 68 of the clamps causing them to pivot outwardly about axes 58 and 60. These jaw portions then remain in contact with the outside wall of the fingers such as shown in figure 6. In this latter figure, the finger extremities 136 are shown extending beyond the threaded neck portion 26a of the cap, but slightly lower than the lower edge of the cap head portion 26b.
Although not shown, springs are used to return the clamps 50 and 52 to their original position afterwards.
Referring to figures 7 and 8, the continuous upward movement of shaft 140 causes the raising of a series of the circumferentially spaced pushing elements 144 displacing the 0-ring 32 off the fingers 136 until it snaps into place under the cap head 26b.
As can be seen in figure 9, the circular trajectories of guides 90 and 92 in the directions indicated by arrows 111 and 113 are transmitted through links 116, 118 to the engaging means 75 and 76 as indicated by arrows 154, 156. Because of the vertical alignment of these engaging means, there is a common tangential trajectory. However, such trajectory is flattened to an horizontal line during the 0-ring transfer onto the cap; these horizontal trajectories are -- - 11- 2ll~8fi indicated by dotted line portions 158 and 160. Referring also to figure 10, this horizontal segment of each circular trajectory is permitted by the action of springs 162 and 164 which are compressed during this segmental travel. During the 0-ring transfer operation, a cap frictionally engaged to the extremity 166 of rod 74 will contact the upper extremity of the 0-ring engaging means 76 prior to the above mentioned tangential point; they remain in contact horizontally under the action of their respective springs 162, 164, which are compressed in a direction away from the contact point.
As can be seen in figure 10, the cap engaging means 75 comprise a holding member 168 secured to the link 116 and in which is housed the spring 162 acting on the vertically moving rod 74. Similarly, the 0-ring engaging means 76 includes the spring 164 which acts against the inner sleeve member 165 onto which are mounted the pushing elements 144.
Rod 74 is movable within the sleeve member 168 (as indicated by arrow 172 in figure 5) which, in turn, is movable vertically (as indicated by arrows 173 in figure 6). As the sleeve 168 is lowered, it contacts the guide rolls 70 and 72 causing the pivotal movement of the cap engaging clamps 46 and 48 about their pivot points 54 and 56. Although not shown, springs are used to return 211~g6~
the clamps 46 and 48 to return to their original position afterwards.
Figures 11-18 pertains to a machine according to the present invention when embodied to insert an O-ring within a cap. The entire machine described abovewith reference to figures 1-10 is not altered when embodying this second embodiment with the exception that the cap engaging means 76 of figures 1-10 are replaced by a modified cap engaging means, generally denoted 200.
10Referring to figure 11, the cap engaging means 200 comprise two separate parts: a funnel shaped member, generally denoted 202, and an O-ring engaging assembly 204. The cap 206 used with the present embodiment is constructed (see figure 13) with a lower inner threaded 15bore 206a and an upper bore 206b into which frictionally fits the lower extremity 166 of the vertical rod 74 of cap engaging means 75.
The funnel member 202 is supported on a bracket 208 secured by means of fastening elements 210, 212 to the chassis 78 of the movable station 20.
Referring to figures 13 and 14, the funnel 202 comprises a cylindrical portion 214, the inner bore of which has a portion defined by inwardly inclined faces 216, a top annular face 218 on which rests the lower -peripheral edge of the cap and a bottom face 219, the function of which will be described hereinbelow.
The 0-ring inserting means 204 is adapted to insert an O-ring 220 into the bore 206a of the cap.
Referring to figure 12, it comprises a hollow cylindrical part 222 having a series of upper extensions 224, 226, 228 and 230 projecting vertically from the upper edge 232 thereof. Within member 222, a cylindrical member 234 is vertically displaceable and includes, at its upper end, 10 a pair of half-cone shaped elements 236, 238. Between these elements 236 and 238 extends a rectangular plate member 240 which is vertically displaceable.
As can be seen in figures 12 and 16, plate 240 is slidably received within the cylindrical member 234 15 and between the cone-shaped elements 236 and 238. This plate may be pushed downwards at the level of the top face 234' of the cylindrical member 234 during the 0-ring transfer operation against the action of a spring 250 which has its lower end bearing against the vertical 20 support 252. This spring serves to return elements 236, 238 and 240 upwards after the O-ring transfer operation is completed.
Figures 12 and 14 illustrate the insertion of the 0-ring 220 within the bore 206a of the cap. The inner inclined faces 216 of the funnel member bend the 0-211~8~
ring in the shape illustrated in figure 12. As elements 226 and 230 reach inside the funnel member and contact the lower edges of the inner inclined walls 216, elements 224 and 228 continue upwards and penetrate slots (not shown) in walls 216. The cylindrical member 234 further continues upwards pushing the 0-ring by the upper edges of the inclined walls 216 to thereafter locate it properly against the top face 254 of the bore of the cap as illustrated in figure 11.
In figure 15, the dotted lines 256 indicate the circular trajectory of the 0-ring engaging means 204 as well as that of the funnel 202. As in the first embodiment illustrated in figures 1-11, there is also provided in this second embodiment a common tangential travel during which the cap transferring elements are maintained in a horizontal direction allowed by the action of spring 250.
For both embodiments illustrated in the drawings, the movable station 20, after the 0-ring transfer operation to the cap, moves towards an entry 260 (see figures 3 and 11) of the rail structure 16. These caps are moved horizontally until they drop into a collecting bin (not shown).
Although the invention has been described above in relation to two specific forms, it will be evident to 2~1~86~
.._ a person skilled in the art that it may be modified and refined in various ways. It is therefore wished to have it understood that the present invention should not be limited in scope, except by the terms of the following claims.
