Abstract
ABSTRACT
A roller entry guide comprises a body with a pair of roller assemblies mounted on the body. The spacing between the assemblies is adjustable by a gear mechanism that induces relative longitudinal displacement between the body and the assemblies. Slides acting between the body and the assemblies produces a lateral component of movement to move the assemblies toward or away from each other whilst maintaining them parallel.

Description
9 ~ ~
The present invention relates to roller entrY quides and in par~icular to a roller entry quide that provides the possibility of adjustment durinq operation.
Roller entry guides are used on a rod ~ill to quide the rod into the next staqe of the mill. Such guides conventionally have a taperinq inlet chute that quides the rod between a set of rollers. The rollers then ensure that the rod is presented to the rolls in the correct orientation.
The roller entry quides are normally set up at the start of a production run so that the spacinq between the rollers corresPonds to the nominal diameter of the rod that will be passing between them. It has been found however that variations in the stock size induce undue wear on the rollers and leads to frequent stoppaqes for adjustment and maintenance.
lS Proposals have been made to bias the rollers against stops so that the rollers may swinq out of the set position should an increase in stock diameter be encountered. Whilst this has been proposed for rollers utilising two rolls it has not been possible to use it where the quide h~s four rollers arranqed in pairs on opposite sides of the material. The use of four rollers is preferred because of the increased stability it provides in operation but it is then essential that the pairs of rollers be maintained parallel to one another at all times.
Howe~er, with the currently available arranqements of four roller entrY quides~ any variation in material thickness requires a production run to be stopped for subse~uent readjustment of the roller entry guides.
~;237~ 3 - 3:~
It is therefore an object of the present invention to provide a roller entry guide in which adjustment may be made whilst the material is passing through the roller entry guide to obviate or mitigate the above disadvantages.
According there~ore to the present invention there is provided a roller entry guide to guide material along a longitudinal axis, said guide having a body, a pair of generally parallel roller assemblies moveably mounted on said body, each of the iroller assemblies being located on an opposite side of said longitudinal axis to define a passageway for material moving along said axis, each of said roller assemblies including an arm and a roller rotatably mounted on said arm for engagement with material passing through said passageway, adjustment means acting between said roller assemblies and said body to induce relative movement therebetween and guide means comprising co-operating slides including a passageway inclined to said longitudinal axis, said slides acting between said roller assemblies and said body to guide said roller assemblies at an angle toward and away from said longitudinal axis, and inhibit rotation of said arms relative to said body, said slides maintaining said roller assemblies in a predetermined disposition relative to said longitudinal axis upon movement induced by said ad;usting means to displace said roller assemblies relative to said longitudinal axis.
An embodiment of the invention will now be described by way of example only with reference to the accompanying drawings in which:-7~ 3 - 3a -Figure 1 is a general perspective view of a roller entry guide.

Fi~ure 4 is 3 section on the line 4 - 4 of fiqure 3.
Fiqure 5 is a plan view, with the top plate removed and partly in section, of the roller entry guide shown in figure 2.
Fiqure 6 is a view of the underside of the top plate used on the guide shown in figures 1 to 5.
Referrinq now to the drawings, a roller entry quide 10 comprises a base plate 12 and a top plate 14 which are located on opposite faces of a body member qener~lly desiqnated 16 and secured thereto by set screws 50. The body member 16 is provided with a bore 17 that extends along the lonqitudinal axis of the ~uide 10 from a rear face 19 to a contoured nose 21. An inlet chute 18 having a throat 20 of pro~ressively reducinq cross section is threaded into the bore 17 and secured by set screws 23.
Projecting from the rear face 19 of the body 16 is an annular boss 36 that has a male tbread 38 to cooperate with a female thread 39 of a collar 40. The rear portion of the collar 40 is flared to accommodate the inlet chute 1~ and terminates in an outwardly directed circumferential qroove 72.
The base plate 12 and top plate 14 project laterally and forwardly beyond the peri~eter of body 16 to provide upper and lower opposed surfaces 42, 44 respectively. Each of the opposed surfaces 42, 44 of the plates 12, 14 is provided with guide means in the form of 4 grooves 46 arranged in pairs on opposite sides of the lonqitudinal axis. The ~rooves 46 in each pair are parallel to one another and are inclined to the longitudinal axis of the roller entry guide 10. The grooves 46 on opposite sides of the longitudinal axis are inclined at equal but opposite anqles to the longitudinal axis to converqe rearwardly toward the rear face l9 of body 16.
The top plate 14 is provided with an upstanding boss 52 5 that projects rearwardly from the top plate l4 and is provided with a trar.sverse bore 54. Located in the bore 54 is a worm wheel 56 ~hat is rotatably supported at opposite ends by bearinqs 58. The worm wheel 56 is formed with a hexa~onal recess 60 at each end to receive a standard hexaqonal wrench. A
10 slot 48 is provided in the undersurface of boss 52 to intersect the bore 54 and receive a rinq qear 62 that meshes with the worm wheel 56. The rin~ qear 62 is provided with internal splines 64 th~t mesh with external spLines 66 provided on the outer surface of the collar 40. The splines 64 - 66 are orientated along the 15 lonqitudinal axis of the roller entry quide 10 so that the collar 40 may move alonq the longitudinal axis relative to the ring gear 62. Lonc~itudinal movement of the ring qear 62 is prevented by opposed walls 68 of the slot 48 in the under surface of the boss 52.
Located between the top plate, and base plate 14 - 12 are a pair of roller assemblies 22, each of which comprises an arm 24 carryin~ a pair of rollers 26 spaced alonq the longitudinal axis of the arm 24. Each of the rollers 26 is mounted on a vertical sp;ndle 30 and provided with conventional 25 bearing assemblies for rotation about a vertical axis.
Projectinq rearwardly from each of the arms 24 is an extension 76 that is part circular in cross-section to accommodate the collar 40 and 3110w rotation of the collar about the lonqitudinal axis. Each extension 74 terminates in a transversely directed flanqe 74 that is received in the qroove 72 of collar 40.
Upper and lower surfaces 78 - 80 respectively of the roller arms 24 a~e each provided ~ith a ~air of upstandinq ribs 82 that are complimentary in shape to the qrooves 45 and co-operate with the qrooves 46 so that lon~itudinal displacement of the arms 24 induces a corresponding lateral d;splacement.
Each of the rollers 26 is waisted so that opposed rollers 26 define a passage for cod passinq throuqh the chute l8 to the roll. For close control of the entry of the rod into the roll of the mill the spacinq between the opposed surfaces of the rollers 26 should correspond to the nominal diameter of the rod. The quide 10 permits adjustment of this spacinq durinq passage of the rod to accommodate minor variations in stock size.
Adjustment of the spacinq between the rollers 26 is achieved by rotation of the worm wheel 56 in the bore 54. Upon rotation of the worm wheel, the rinq gear 62 rotates about the lonqitudinal axis and causes a corresponding rotation of the collar 40. Such rotation causes intermeshing threads 38, 39 between the annular boss 36, and collar 40 to induce lonqitudinal displacement of the collar 40. This motion is transmitted to the the roller arms 27 through the flanqes 74 to cause a correspondinq longitudinal displacement of the roller assemblies. The co-operatinq qrooves and ribs 82 cause the roller assemblies to move laterally upon longitudinal 3~
displacement and thereby alter the ~P between the rollers.
However, because the roller arms 26 are supported at two locations by the qrooves, the two arms remain parallel to one another so that the spacing between the front and rear pairs of rollers 26 remains constant.
The disposition of the ribs and projections ensures that adequate later31 support is provided for the roller assemblies to resist the lateral forces produced by the rod material passinq throuqh the roller entry quide 10 whilst at the same time ensuring that the sets of rollers remain parallel at all times. The worm and wheel arranqement permits adjustment of the roller entry guides from the side of the guide without interrupting the flow of material and can be used to either increase or decrease the space between the rollers depending upon the direction of rotation of the worm wheel.
The present invention relates to roller entrY quides and in par~icular to a roller entry quide that provides the possibility of adjustment durinq operation.
Roller entry guides are used on a rod ~ill to quide the rod into the next staqe of the mill. Such guides conventionally have a taperinq inlet chute that quides the rod between a set of rollers. The rollers then ensure that the rod is presented to the rolls in the correct orientation.
The roller entry quides are normally set up at the start of a production run so that the spacinq between the rollers corresPonds to the nominal diameter of the rod that will be passing between them. It has been found however that variations in the stock size induce undue wear on the rollers and leads to frequent stoppaqes for adjustment and maintenance.
lS Proposals have been made to bias the rollers against stops so that the rollers may swinq out of the set position should an increase in stock diameter be encountered. Whilst this has been proposed for rollers utilising two rolls it has not been possible to use it where the quide h~s four rollers arranqed in pairs on opposite sides of the material. The use of four rollers is preferred because of the increased stability it provides in operation but it is then essential that the pairs of rollers be maintained parallel to one another at all times.
Howe~er, with the currently available arranqements of four roller entrY quides~ any variation in material thickness requires a production run to be stopped for subse~uent readjustment of the roller entry guides.

It is therefore an object of the present invention to provide a roller entry guide in which adjustment may be made whilst the material is passing through the roller entry guide to obviate or mitigate the above disadvantages.
According there~ore to the present invention there is provided a roller entry guide to guide material along a longitudinal axis, said guide having a body, a pair of generally parallel roller assemblies moveably mounted on said body, each of the iroller assemblies being located on an opposite side of said longitudinal axis to define a passageway for material moving along said axis, each of said roller assemblies including an arm and a roller rotatably mounted on said arm for engagement with material passing through said passageway, adjustment means acting between said roller assemblies and said body to induce relative movement therebetween and guide means comprising co-operating slides including a passageway inclined to said longitudinal axis, said slides acting between said roller assemblies and said body to guide said roller assemblies at an angle toward and away from said longitudinal axis, and inhibit rotation of said arms relative to said body, said slides maintaining said roller assemblies in a predetermined disposition relative to said longitudinal axis upon movement induced by said ad;usting means to displace said roller assemblies relative to said longitudinal axis.
An embodiment of the invention will now be described by way of example only with reference to the accompanying drawings in which:-7~ 3 - 3a -Figure 1 is a general perspective view of a roller entry guide.
Figure 2 is a side view of -the roller entry guide shown in Figure 1.

Fiqure 5 is a plan view, with the top plate removed and partly in section, of the roller entry guide shown in figure 2.
Fiqure 6 is a view of the underside of the top plate used on the guide shown in figures 1 to 5.
Referrinq now to the drawings, a roller entry quide 10 comprises a base plate 12 and a top plate 14 which are located on opposite faces of a body member qener~lly desiqnated 16 and secured thereto by set screws 50. The body member 16 is provided with a bore 17 that extends along the lonqitudinal axis of the ~uide 10 from a rear face 19 to a contoured nose 21. An inlet chute 18 having a throat 20 of pro~ressively reducinq cross section is threaded into the bore 17 and secured by set screws 23.
Projecting from the rear face 19 of the body 16 is an annular boss 36 that has a male tbread 38 to cooperate with a female thread 39 of a collar 40. The rear portion of the collar 40 is flared to accommodate the inlet chute 1~ and terminates in an outwardly directed circumferential qroove 72.
The base plate 12 and top plate 14 project laterally and forwardly beyond the peri~eter of body 16 to provide upper and lower opposed surfaces 42, 44 respectively. Each of the opposed surfaces 42, 44 of the plates 12, 14 is provided with guide means in the form of 4 grooves 46 arranged in pairs on opposite sides of the lonqitudinal axis. The ~rooves 46 in each pair are parallel to one another and are inclined to the longitudinal axis of the roller entry guide 10. The grooves 46 on opposite sides of the longitudinal axis are inclined at equal but opposite anqles to the longitudinal axis to converqe rearwardly toward the rear face l9 of body 16.
The top plate 14 is provided with an upstanding boss 52 5 that projects rearwardly from the top plate l4 and is provided with a trar.sverse bore 54. Located in the bore 54 is a worm wheel 56 ~hat is rotatably supported at opposite ends by bearinqs 58. The worm wheel 56 is formed with a hexa~onal recess 60 at each end to receive a standard hexaqonal wrench. A
10 slot 48 is provided in the undersurface of boss 52 to intersect the bore 54 and receive a rinq qear 62 that meshes with the worm wheel 56. The rin~ qear 62 is provided with internal splines 64 th~t mesh with external spLines 66 provided on the outer surface of the collar 40. The splines 64 - 66 are orientated along the 15 lonqitudinal axis of the roller entry quide 10 so that the collar 40 may move alonq the longitudinal axis relative to the ring gear 62. Lonc~itudinal movement of the ring qear 62 is prevented by opposed walls 68 of the slot 48 in the under surface of the boss 52.
Located between the top plate, and base plate 14 - 12 are a pair of roller assemblies 22, each of which comprises an arm 24 carryin~ a pair of rollers 26 spaced alonq the longitudinal axis of the arm 24. Each of the rollers 26 is mounted on a vertical sp;ndle 30 and provided with conventional 25 bearing assemblies for rotation about a vertical axis.
Projectinq rearwardly from each of the arms 24 is an extension 76 that is part circular in cross-section to accommodate the collar 40 and 3110w rotation of the collar about the lonqitudinal axis. Each extension 74 terminates in a transversely directed flanqe 74 that is received in the qroove 72 of collar 40.
Upper and lower surfaces 78 - 80 respectively of the roller arms 24 a~e each provided ~ith a ~air of upstandinq ribs 82 that are complimentary in shape to the qrooves 45 and co-operate with the qrooves 46 so that lon~itudinal displacement of the arms 24 induces a corresponding lateral d;splacement.
Each of the rollers 26 is waisted so that opposed rollers 26 define a passage for cod passinq throuqh the chute l8 to the roll. For close control of the entry of the rod into the roll of the mill the spacinq between the opposed surfaces of the rollers 26 should correspond to the nominal diameter of the rod. The quide 10 permits adjustment of this spacinq durinq passage of the rod to accommodate minor variations in stock size.
Adjustment of the spacinq between the rollers 26 is achieved by rotation of the worm wheel 56 in the bore 54. Upon rotation of the worm wheel, the rinq gear 62 rotates about the lonqitudinal axis and causes a corresponding rotation of the collar 40. Such rotation causes intermeshing threads 38, 39 between the annular boss 36, and collar 40 to induce lonqitudinal displacement of the collar 40. This motion is transmitted to the the roller arms 27 through the flanqes 74 to cause a correspondinq longitudinal displacement of the roller assemblies. The co-operatinq qrooves and ribs 82 cause the roller assemblies to move laterally upon longitudinal 3~
displacement and thereby alter the ~P between the rollers.
However, because the roller arms 26 are supported at two locations by the qrooves, the two arms remain parallel to one another so that the spacing between the front and rear pairs of rollers 26 remains constant.
The disposition of the ribs and projections ensures that adequate later31 support is provided for the roller assemblies to resist the lateral forces produced by the rod material passinq throuqh the roller entry quide 10 whilst at the same time ensuring that the sets of rollers remain parallel at all times. The worm and wheel arranqement permits adjustment of the roller entry guides from the side of the guide without interrupting the flow of material and can be used to either increase or decrease the space between the rollers depending upon the direction of rotation of the worm wheel.
