Field of the-Invention The present invention relates to a guide rail support for a conveyor line, and is particularly applicable to quick-change adjustable guide rails for conveyor lines for bottling apparatus.
Back~round of the Invention Conveyor lines for bottles normally have rails positioned along opposite sides of the line in order to prevent the bottles from falling away from the moving conveyor belt. The side rails are disposed on opposite sides of the conveyor belt and the bottles travel between the fixed rails. When a conveyor line is converted to transport bottles of different size, the conventional method for adjusting the spacing of the side rails depends on the skills of the mechanics to avoid maladjustment.
Quick-change mounts for the side rails have been proposed, but the need for precise adjustment of the side rails after changing their position has made such quick-change adjustments subject to mechanic error.
SummarY of the Invention The present invention provides an adjustable support for a conveyor side rail which is easily adjusted to predetermined positions with little mechanical skill on the part of the operator.
More specifically, the present invention provides a simple and effective device for adjusting the lateral positions of the side rails on a conveyor system among a plurality of pre-set positions.
CA 0221191~ 1997-08-19 .
The first embodiment of the adjusting mechanism includes a spring-loaded latch which cooperates with a toothed member mounting the side rail to enable longitudinal adjustment of the member and thereby the side rail by releasing the spring latch and latching of the member in adjusted position by engagement of the latch in receptacles provided by the teeth of the toothed member. The latch of the present invention is a self-contained unit which maintains its operability under harsh operating conditions and is not subject to jamming or operating failures when installed in areas which are subject to contamination by dust, or spillage of product.
The second embodiment of the adjusting mechanism includes a spring-loaded member mounting a side rail arm having a fixed latch pin, and an adjustable stop having a plurality of receptacles for engaging the latch pin for determining the longitl]~- n~l position of the arm, and thereby the side rail. The adjustable stop provides multiple positions, each position providing a side rail position accommodating a bottle of a given size.

DeRcription of the Preferred Embodiments Fig. 1 illustrates the first embodiment of a mounting assembly embodying the present invention. As shown, there is a mounting bracket 11 adapted to be mounted alongside the conveyor belt having an arm projecting angularly upward and outward to terminate in a seating flange 12. The flange 12 mounts an upstanding shaft 14, for example in the form of a post having a vertical through-bore 15 threaded at the lower end to receive a bolt 16 which anchors the post 14 to the flange in an upright position. The post 14 is provided with a transverse slot or through-slot 17 adapted to slidably receive an elongated arm 21 having a guide-rail bracket 22 mounted on its inner end so as to overlie the conveyor. The slot 17 is generally perpendicular to the path of travel of the conveyor belt. The bracket 22 is adapted to mount guide rails or bumpers (not shown in Fig. 1, but shown at 89 in Fig. 4) extending parallel to the conveyor. The lower surface of the mounting arm 21 is toothed, i.e.
provided with a series of notches or receptacles 25 which, in the present instance, are equally spaced along the length of the arm.
A stop mechanism is mounted on the upright post 14 to latch the arm at any selected position determined by the receptacles 25. To this end, a hollow cap 31 is telescopically engaged with the post 14 for relative vertical movement. The hollow cap 31 has slots 32,32 on opposite sides which are CA 0221191~ 1997-08-19 sufficiently wide to accommodate the arm 21 when the cap slots 32 are in registry with the through-slot 17 of the post. A spring 33 is captured within the hollow cap and is seated at one end in the top portion of the cap and seated in the other end against the top of the post 14, thereby biasing the cap upwardly relative to the post. The cap is displaceable downwardly on the post against the bias of the spring 33 to cause the cap slots 32 to register with the through-slot 16 of the post.
The hollow cap 33 below the slot 32, as indicated at 35 in Fig. 1, has a wall thickness corresponding to or less than the width of the receptacles 25. The distance between the opposite sides of the cap between lS the side wall portions 35,35 corresponds to a spacing between the receptacles 25, so as to enable the cap wall portions at the bottom of the openings forming the cap slots 32 to latch the toothed arm 21 in adjusted position. In this case, the spacing between the marginal wall portions 35 is an integral multiple of the spacing between adjacent receptacles, e.g.
twice the spacing between adjacent receptacles, so that marginal portions of the openings which form the through slots 32,32 in the hollow cylindrical wall serve as latches selectively engaging the receptacles.
Thus, the spacings of the receptacles 25 in the arm 21 permit longitudinal adjustment of the arm in increments equal to the spacing between the receptacles which is one half the spacing between the side walls 35.
The cap 31 is retained on the post 14 by the arm 21 passing through the slots 32. It may be removed from the post by removing the arm and lifting the cap away from the top of the post. To this end, the bracket 22 is removably mounted on the arm 21 so that upon removal of the bracket, the cap 31 may be CA 022ll9l~ l997-08-l9 depressed and the arm can be retracted through the registering slots 16 and 32. Alternatively, the other end of the arm may be modified to enable the other end to be advanced through and beyond the registering slots.
Figs. 2 and 3 illustrate the second embodiment of a mounting assembly embodying the present invention.
As shown, there is a mounting bracket 41 adapted to be mounted alongside the conveyor belt having an arm projecting angularly upward and outward to terminate in a seating flange 42. The flange 42 mounts an -upstanding post 44, having a ~ertical bore 45 threaded to receive a bolt 46 which anchors the post 44 to the flange in an upright position. The post 44 mounts a transverse sleeve 47 adapted to slidably receive an elongated arm 51 having a guide-rail bracket 48 mounted on its inner end so as to overlie the conveyor. The bracket 48 iS adapted to mount rails or bumpers 49 extending parallel to the conveyor.
The mounting arm 51 comprises a cylindrical rod and is displaceable longitudinally within the sleeve 47 toward and away from the conveyor path of travel.
The arm 51 iS biased axially in a direction away from the conveyor by a coil spring 52 mounted within the sleeve 47 and seated at one end against a stop washer 53 on the arm and at the other end against a bottom plug 54 anchored in the inner end of the sleeve 47 which, in turn, is fixed in the post 44. The rod 51 is slidable through the bottom plug 54 SO as to be displaceable longitudinally within the sleeve.
Means is provided to selectively position the rod 51 at one of a plurality of settings. An adjustable hollow cylindrical stop member 56 iS rotatable about the longitudinal axis of the rod 51. The stop 56 has a cylindrical bore which slidably and rotatably receives the rod 51. At one end, the adjustable stop CA 0221191~ 1997-08-19 56 bears against the inner end of the end wall 54 of the sleeve 47 and/or the plug 54. At its other end, the adjustable stop is provided with a series of axially-extending slots or receptacles 61, 62 and 63 arranged in diametrically opposite pairs. In the present instance, the receptacles 61, 62 and 63 pass through the cylindrical wall of the hollow cylindrical stop member 56 as shown in Fig. 3. Each pair of slots 61, 62 and 63 has diametrically opposite segments in the hollow cylindrical wall, and the pairs are positioned at 60~ increments about the circumference of the wall.
The adjustable stop member 56 operates to position the mounting arm 51 and at one of three settings determined by the receptacle pairs 61, 62 and 63. To this end, the arm 51 is provided with a latch pin 65 projecting from the arm 51 at diametrically opposite points so as to engage in the diametrically opposite components of the receptacle pairs 61, 62 and 63.
In operation, to adjust the position the bracket 48, the rod 51 is thrust inwardly toward the conveyor against the bias of the spring 52 so as to free the latch pin 65 from the receptacles in which it is engaged. Once the pin is free from the receptacles, the adjustable stop 56 may be rotated to register a second receptacle pair with the latch. Releasing the arm 51 thereby engages the latch in the new receptacle pair and repositions the new bracket 48 to the setting determined by the depth of the receptacle pair. Thus, the position of the bracket 48 may be quickly adjusted to any one of the three settings provided by the receptacles 61, 62 and 63 in the adjustable stop 56.
The innermost setting of the bracket 48 is illustrated in Fig. 2a, and is determined by the spacing between the outer end of the slot 53 and the CA 0221191~ 1997-08-19 . , .
inner end of the sleeve 47. The intermediate setting is illustrated in Fig. 2b, and is determined by the spacing between the outer end of the slot 62 and the inner end of the sleeve 47. The outermost setting is illustrated in Fig. 2c, and is determined by the spacing between the outer limit of the receptacle 61 at the inner end of the stop member 56 and the inner end of the sleeve 47. In this embodiment of the invention each position of the bracket 48 may be selected independently of the other positions. If more than three alternative positions are required, a second stop member having the required receptacles may replace the membe~ 56.
Fig. 4 shows a prior art conveyor in which a conveyor 80 has a run 81 which travels on a bed 82 formed by confronting channel members. At intervals along the bed 82, for example 4-6" intervals, mounting brackets 83 project outwardly and upwardly and terminate in upstanding posts 84. Each post has a through-slot (not shown) for accommodating the arm 85 which mounts at its inner end a rail 87 for supporting and positioning bumpers 89. The post 84 has a through-bore into which is threaded a thumb screw 88.
The thumbscrew 88 has an adjusting knob at the top and a threaded shaft which engages in the bore and bears against the arm 85 as it passes through the post 84, thereby anchoring the arm against lateral movement through this slot. When it is desired to change the spacing between the guide rails 87, the mechanic releases the thumb screw 88 and adjusts the arm 85 to proper extent to provide the desired spacing between the rails 87,87. As is apparent, the proper adjustment of the side rails 87 relies on the ability of the mechanics to properly position the arms 85 in the posts 84 so as to overlie the conveyor 81 as desired.
CA 0221191~ 1997-08-19 .
Comparing the first embodiment of the present invention to the device shown in Fig. 4, the notches or receptacles 25 provide a limited number of settings in which the arm 21 may be positioned so that by placing the corresponding notches under the latch cap 31, it is possible to adjust all of the arms to the precise same extent, thereby achieving a precise readjustment of the guard rail 22. The cap 31 is fixed relative to the conveyor and serves as a stop engaging the series of receptacles on the arm 21, and also serves to shield the working parts of the quick-change adjusting mechanism from contamin~tion by the dirt and other co~t~m;n~nts which may be present in the area of the conveyor.
Comparing the second embodiment to the adjusting assembly shown in Fig. 4, the adjustable stop assures proper positioning of the side rails, in one of three pre-set settings at each side of the conveyor run.
The adjustable stop engages a latch pin fixed on the arm and providing a series of receptacles providing the designed spacings from sleeve which is fixed relative to the conveyor. In this way the opportunity for mechanic error in adjusting the side rails to accommodate differently sized bottles is minimized.
While particular embodiments of the invention have been herein illustrated and described, it is not intended to limit the invention to such disclosures, but changes and modifications may be made therein and thereto within the scope of the following claims.

DeRcription of the Preferred Embodiments Fig. 1 illustrates the first embodiment of a mounting assembly embodying the present invention. As shown, there is a mounting bracket 11 adapted to be mounted alongside the conveyor belt having an arm projecting angularly upward and outward to terminate in a seating flange 12. The flange 12 mounts an upstanding shaft 14, for example in the form of a post having a vertical through-bore 15 threaded at the lower end to receive a bolt 16 which anchors the post 14 to the flange in an upright position. The post 14 is provided with a transverse slot or through-slot 17 adapted to slidably receive an elongated arm 21 having a guide-rail bracket 22 mounted on its inner end so as to overlie the conveyor. The slot 17 is generally perpendicular to the path of travel of the conveyor belt. The bracket 22 is adapted to mount guide rails or bumpers (not shown in Fig. 1, but shown at 89 in Fig. 4) extending parallel to the conveyor. The lower surface of the mounting arm 21 is toothed, i.e.
provided with a series of notches or receptacles 25 which, in the present instance, are equally spaced along the length of the arm.
A stop mechanism is mounted on the upright post 14 to latch the arm at any selected position determined by the receptacles 25. To this end, a hollow cap 31 is telescopically engaged with the post 14 for relative vertical movement. The hollow cap 31 has slots 32,32 on opposite sides which are CA 0221191~ 1997-08-19 sufficiently wide to accommodate the arm 21 when the cap slots 32 are in registry with the through-slot 17 of the post. A spring 33 is captured within the hollow cap and is seated at one end in the top portion of the cap and seated in the other end against the top of the post 14, thereby biasing the cap upwardly relative to the post. The cap is displaceable downwardly on the post against the bias of the spring 33 to cause the cap slots 32 to register with the through-slot 16 of the post.
The hollow cap 33 below the slot 32, as indicated at 35 in Fig. 1, has a wall thickness corresponding to or less than the width of the receptacles 25. The distance between the opposite sides of the cap between lS the side wall portions 35,35 corresponds to a spacing between the receptacles 25, so as to enable the cap wall portions at the bottom of the openings forming the cap slots 32 to latch the toothed arm 21 in adjusted position. In this case, the spacing between the marginal wall portions 35 is an integral multiple of the spacing between adjacent receptacles, e.g.
twice the spacing between adjacent receptacles, so that marginal portions of the openings which form the through slots 32,32 in the hollow cylindrical wall serve as latches selectively engaging the receptacles.
Thus, the spacings of the receptacles 25 in the arm 21 permit longitudinal adjustment of the arm in increments equal to the spacing between the receptacles which is one half the spacing between the side walls 35.
The cap 31 is retained on the post 14 by the arm 21 passing through the slots 32. It may be removed from the post by removing the arm and lifting the cap away from the top of the post. To this end, the bracket 22 is removably mounted on the arm 21 so that upon removal of the bracket, the cap 31 may be CA 022ll9l~ l997-08-l9 depressed and the arm can be retracted through the registering slots 16 and 32. Alternatively, the other end of the arm may be modified to enable the other end to be advanced through and beyond the registering slots.
Figs. 2 and 3 illustrate the second embodiment of a mounting assembly embodying the present invention.
As shown, there is a mounting bracket 41 adapted to be mounted alongside the conveyor belt having an arm projecting angularly upward and outward to terminate in a seating flange 42. The flange 42 mounts an -upstanding post 44, having a ~ertical bore 45 threaded to receive a bolt 46 which anchors the post 44 to the flange in an upright position. The post 44 mounts a transverse sleeve 47 adapted to slidably receive an elongated arm 51 having a guide-rail bracket 48 mounted on its inner end so as to overlie the conveyor. The bracket 48 iS adapted to mount rails or bumpers 49 extending parallel to the conveyor.
The mounting arm 51 comprises a cylindrical rod and is displaceable longitudinally within the sleeve 47 toward and away from the conveyor path of travel.
The arm 51 iS biased axially in a direction away from the conveyor by a coil spring 52 mounted within the sleeve 47 and seated at one end against a stop washer 53 on the arm and at the other end against a bottom plug 54 anchored in the inner end of the sleeve 47 which, in turn, is fixed in the post 44. The rod 51 is slidable through the bottom plug 54 SO as to be displaceable longitudinally within the sleeve.
Means is provided to selectively position the rod 51 at one of a plurality of settings. An adjustable hollow cylindrical stop member 56 iS rotatable about the longitudinal axis of the rod 51. The stop 56 has a cylindrical bore which slidably and rotatably receives the rod 51. At one end, the adjustable stop CA 0221191~ 1997-08-19 56 bears against the inner end of the end wall 54 of the sleeve 47 and/or the plug 54. At its other end, the adjustable stop is provided with a series of axially-extending slots or receptacles 61, 62 and 63 arranged in diametrically opposite pairs. In the present instance, the receptacles 61, 62 and 63 pass through the cylindrical wall of the hollow cylindrical stop member 56 as shown in Fig. 3. Each pair of slots 61, 62 and 63 has diametrically opposite segments in the hollow cylindrical wall, and the pairs are positioned at 60~ increments about the circumference of the wall.
The adjustable stop member 56 operates to position the mounting arm 51 and at one of three settings determined by the receptacle pairs 61, 62 and 63. To this end, the arm 51 is provided with a latch pin 65 projecting from the arm 51 at diametrically opposite points so as to engage in the diametrically opposite components of the receptacle pairs 61, 62 and 63.
In operation, to adjust the position the bracket 48, the rod 51 is thrust inwardly toward the conveyor against the bias of the spring 52 so as to free the latch pin 65 from the receptacles in which it is engaged. Once the pin is free from the receptacles, the adjustable stop 56 may be rotated to register a second receptacle pair with the latch. Releasing the arm 51 thereby engages the latch in the new receptacle pair and repositions the new bracket 48 to the setting determined by the depth of the receptacle pair. Thus, the position of the bracket 48 may be quickly adjusted to any one of the three settings provided by the receptacles 61, 62 and 63 in the adjustable stop 56.
The innermost setting of the bracket 48 is illustrated in Fig. 2a, and is determined by the spacing between the outer end of the slot 53 and the CA 0221191~ 1997-08-19 . , .
inner end of the sleeve 47. The intermediate setting is illustrated in Fig. 2b, and is determined by the spacing between the outer end of the slot 62 and the inner end of the sleeve 47. The outermost setting is illustrated in Fig. 2c, and is determined by the spacing between the outer limit of the receptacle 61 at the inner end of the stop member 56 and the inner end of the sleeve 47. In this embodiment of the invention each position of the bracket 48 may be selected independently of the other positions. If more than three alternative positions are required, a second stop member having the required receptacles may replace the membe~ 56.
Fig. 4 shows a prior art conveyor in which a conveyor 80 has a run 81 which travels on a bed 82 formed by confronting channel members. At intervals along the bed 82, for example 4-6" intervals, mounting brackets 83 project outwardly and upwardly and terminate in upstanding posts 84. Each post has a through-slot (not shown) for accommodating the arm 85 which mounts at its inner end a rail 87 for supporting and positioning bumpers 89. The post 84 has a through-bore into which is threaded a thumb screw 88.
The thumbscrew 88 has an adjusting knob at the top and a threaded shaft which engages in the bore and bears against the arm 85 as it passes through the post 84, thereby anchoring the arm against lateral movement through this slot. When it is desired to change the spacing between the guide rails 87, the mechanic releases the thumb screw 88 and adjusts the arm 85 to proper extent to provide the desired spacing between the rails 87,87. As is apparent, the proper adjustment of the side rails 87 relies on the ability of the mechanics to properly position the arms 85 in the posts 84 so as to overlie the conveyor 81 as desired.
