TECHNICAL FIELD OF THE INVENTION
The present invention relates to a rectangular steel material transfer device.
[0002]
[Prior art]
A steel slab such as a billet or bloom or other long steel object having a square cross section (hereinafter collectively referred to as "square steel material") is turned 45 ° around the center of the cross section. Various methods have been proposed.
For example, Japanese Utility Model Laid-Open No. 4-113104 discloses that rollers having a truncated cone are arranged so that the small-diameter side of the truncated cone is staggered across the transport line, and one side of the transport line. (Hereinafter referred to as "first conventional device") in which a roller row of frusto-conical cones arranged in a row can be moved toward and away from a roller row of frusto-conical cones arranged in the other side.
[0003]
This first conventional apparatus changes a rectangular steel material, which has been placed flat with respect to the transport line when the roller rows are separated from each other, into an upright state (45 ° turning state) with respect to the transport line when the roller rows are close to each other. It is made to let.
In Japanese Patent Application Laid-Open No. Hei 7-124622, a mountain-shaped crossing track having two lower ends and a middle height is provided between two parallel roller lines, and a mounting vehicle can be freely moved on the crossing track. A device in which a taper roller having the same direction as the downward inclination of the traverse track and a flat roller which rises in the opposite diagonal direction to the roller line at the delivery destination are kept on standby (hereinafter referred to as “second conventional device”). Is described).
[0004]
In this second conventional apparatus, a rectangular steel material is placed on a loading carriage in a flat state from a roller line of a delivery source and is laterally fed to a roller line of a delivery destination. As the trolley becomes inclined along the downward slope of the traverse track, the square steel material is kept at a 45 ° turning state to the V-shaped portion by the taper roller and the flat roller in the roller line of the delivery destination. , To be delivered.
In Japanese Utility Model Laid-Open Publication No. Sho 62-41728, a double link mechanism combined in a complex manner is provided at a side position of a V-roller for transporting a square steel material, and the double link mechanism is provided for each fluid. A device that is operated simultaneously by a pressure cylinder (hereinafter referred to as a "third conventional device") is described.
[0005]
In the third conventional apparatus, as a simultaneous operation of the double link mechanism, the square steel material on the V roller (that is, the square steel material is initially in an obliquely upright state) is scooped up and the front side (double At the same time as the link mechanism), and at the same time, a movement such as turning the square steel material by 45 ° to place it in a flat state is taken out.
Japanese Patent Application Laid-Open No. 11-139556 discloses that a transverse track is provided between a cradle on which a rectangular steel material is placed in an upright position of 45 ° and a transfer line provided on the side of the cradle. A loading cart is provided movably, and the loading cart is provided with a vertically movable rocking rod, and a V-shaped loading section for loading a square steel material is provided at an upper end side of the loading rod. A device in which the lower end of a rod is wrapped around a pulley device by an endless chain (hereinafter referred to as a "fourth conventional device") is described.
[0006]
In the fourth conventional apparatus, when the transfer cart is on the cradle side, one pulley of the pulley device is moved away from the other pulley to raise and swing the loading rod, thereby taking out the square steel material from the cradle. By moving the pulley device (rotating the pulley), the transfer carriage is moved to the transport line, and on this transport line side, the pulley spacing of the pulley device is returned to the original (closer) and the loading rod descends and swings. The rectangular steel material is transferred to the transport line.
In addition, the upper surface level of the transfer line is set lower than the cradle, and the swing angle of the loading rod is made large, causing a difference in the inclination of the loading part when removing and sending the rectangular steel material. Thereby, the square steel material is turned by 45 °.
[0007]
[Problems to be solved by the invention]
In the first conventional apparatus, it is only possible to turn the rectangular steel by 45 °, but it is not possible to feed the rectangular steel transversely in a direction orthogonal to the longitudinal direction or to raise and lower the rectangular steel. For this reason, the first conventional apparatus is designed to transfer a hot billet transfer roller (a plurality of rolls) from a primary-side transfer device having a V-roll when a rectangular steel material rolled by a billet rolling mill is carried into a heat retaining furnace. It cannot be used as it is as a means for transferring to a secondary-side transfer device having a transfer roller groove and a partition flange protruding between the transfer roller grooves.
[0008]
Further, in the first conventional apparatus, there is a problem that it is inconvenient to stabilize the quality because it is not determined whether to turn right or left due to the delicate balance of the square steel material at the time of 45 ° turning.
In the second conventional apparatus, the rectangular steel material can be turned 45 ° and traversed, but cannot be moved up and down. Therefore, the second conventional apparatus cannot be used as it is as a transfer means for the transfer apparatus having the hot billet transfer roller as described above.
[0009]
Further, in the second conventional apparatus, when the rectangular steel material is transferred from the mounting cart to the roller line (the portion formed into a V shape by the taper roller and the flat roller) at the transfer destination, the rectangular steel material slides down on the taper roller. At this time, there was a problem that the square steel material was scratched.
In the third conventional apparatus, the rectangular steel material can be turned 45 ° or traversed, and furthermore, can be raised and lowered at the time of taking out and delivering the square steel material, but the takeout position and the delivery position are uniquely fixed. There was a problem. This is because, when there is a request to individually deliver a square steel material to each of the plurality of transport roller grooves, such as the above-described hot billet transfer roller, the third conventional apparatus also has the above-described structure. However, it has been unsuitable as a transfer means for a transfer device having such a hot billet transfer roller.
[0010]
Further, in the third conventional apparatus, separate hydraulic cylinders are required for the double link mechanism, and there is a problem that the structure is complicated and large.
The fourth conventional apparatus has a problem that the cradle (before turning the square steel 45 °) and the transfer line (after turning the square steel 45 °) cannot be at the same level. This is a fatal drawback for judging the adoption of a rolling line or the like where it is generally common to make the conveying level of the rectangular steel material substantially constant. Also in this fourth conventional device, a hydraulic device for expanding / contracting the pulley interval in the pulley device and a drive device for driving the pulley device (rotating the pulley) are separately required, and are structurally complicated. In addition, there was a problem of increasing the size.
[0011]
The present invention has been made in view of the above circumstances, and a 45 ° rotation of a square steel material, and traverse in a direction orthogonal to a longitudinal direction can be performed by a simple structure, and before and after traverse. , It is possible to transfer the square steel material to the required places (including a plurality of places) while ascending and descending, and then, as a whole, the structure is simple and the size can be suppressed, and the square shape can be suppressed. An object of the present invention is to provide a rectangular steel material transfer device capable of preventing abrasion or the like from being applied to a steel material.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has taken the following measures.
That is, the rectangular steel material transfer device according to the present invention takes out the rectangular steel material held at the pre-transfer position and turns it around the center of its cross section by 45 °, while the post-transfer position adjacent to the pre-transfer position. Traverse feed to the post-transfer position, and the traverse rail provided between the pre-transfer position and the post-transfer position; A movable carrier, a carriage driving means for reciprocating the carrier between a pre-transfer position and a post-transfer position, and two adjacent rectangular steel members held at the pre-transfer position. A steel support having a V-shaped support surface corresponding to the side surface and swingably provided with respect to the carrier in a range where the V-shaped support is inclined by 45 °; and a position before the carrier is transferred. When moving between the And a cam rail provided along the side of the lateral feed rail to push and swing the steel support from one end to the other end of the swing range.
[0013]
With such a configuration, the steel material provided on the transport trolley is merely moved by moving the transport trolley from the pre-transfer position to the post-transfer position (or in the opposite direction) while moving along the lateral feed rail. A part of the support comes into contact with the cam rail provided along the side of the traverse rail and swings. The swing causes the V-shaped support surface of the steel support to tilt by 45 °. The supported square steel will be turned 45 °.
Therefore, in this transfer device, as a main drive device for enabling both the lateral feeding and the 45 ° turning of the rectangular steel material, only a trolley drive means for moving the transport trolley is required. In addition, the structure can be simplified and the size can be suppressed.
[0014]
In addition, this configuration is advantageous in that 45 ° turning of the square steel material can be performed with a very short distance and reliably.
Furthermore, the stop position of the transport carriage can be arbitrarily changed with respect to the lateral feed rail, and the degree of freedom regarding the positioning and the setting of the number of stop positions, that is, versatility is extremely high.
The traverse rail may be supported so as to be able to move up and down by the elevating means which moves up when the carrier is at the pre-transfer position and moves down when the carrier is at the post-transfer position. That is, if the elevating means moves up and down when the transport vehicle is at the pre-transfer position, the steel support provided on the transport vehicle will scoop up the square steel from the pre-transfer position, and If the lifting / lowering means moves downward at the post-transfer position, the rectangular steel material can be transferred from the steel support to the post-transfer position.
[0015]
As this elevating means, an advancing / retreating driver installed in the direction of extension of the traverse rail, and when receiving an advancing operation from the advancing / retreating driver, lowering the traverse rail and receiving a retreating operation from the advancing / retreating driver. What is necessary is just to have the link mechanism which raises a transverse feed rail.
In this case, the height of the link mechanism when it is lowered can be kept small, which is useful for suppressing the height of the entire apparatus. Further, since the lever action is used, there is an advantage that the driving force can be reduced.
[0016]
Further, when handling a long and rectangular steel material slightly exceeding 10 meters, it is necessary to arrange a number of elevating means in parallel, and in this case, the elevating operation of each elevating means must be synchronized. However, when the link mechanism is employed as described above, synchronization can be ensured only by providing a line shaft (interlocking shaft) in a skewered shape, and in this regard, the structure can be simplified and the size can be suppressed. It is.
When the transport vehicle is at the post-transfer position, and at the stage immediately before the steel material support switches the rectangular steel material to the post-transfer position with the descending movement of the lifting / lowering means, the height of the V-shaped support surface is increased. The height of the V-shaped support surface should be accurate and reliable so that it can be controlled by hitting one end of the swing range in the steel material support with a stopper provided on the carrier. It is preferable in that.
[0017]
In this case, it is preferable that the stopper be capable of adjusting the degree of movement of the contact stop position so that the height of the V-shaped support surface can be finely adjusted. By doing so, when the rectangular steel material is replaced with respect to the post-transfer position, it is possible to reliably obtain a state in which the rectangular steel material does not slide on the post-transfer position or the V-shaped support surface. There is an advantage that the square steel material does not need to be scratched.
It is also preferable that the height of the cam rail can be adjusted by inserting and removing a spacer member from a portion where the cam rail is installed along the side of the lateral feed rail. In this way, when the rectangular steel material is scooped from the pre-transfer position, a state in which the rectangular steel material does not slide on the pre-transfer position or the V-shaped support surface can be reliably obtained. Has the advantage that it does not need to be scratched.
[0018]
On the side of the traverse rail, in the process of moving the carrier from the pre-transfer position to the post-transfer position, at a position closer to the post-transfer position than the contact position between the steel support and the cam rail, It is preferable to provide a forced swing guide. The forced swing guide is intended to complement the swing by reliably contacting a part of the steel support in which the swing failure has occurred.
If this forced swing guide is provided, even if the steel support does not sufficiently swing even if it comes into contact with the cam rail, or even if the cam rail does not come into contact with the steel support, Since the swing of the steel support can be ensured, there is no failure in transferring the square steel.
[0019]
If the cam rail is replaceable with one having a different inclination angle, the moving distance of the carrier cart required to swing the steel support can be shortened, and the time cycle can be shortened accordingly.
[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 4 is an overall layout view showing an embodiment of the transfer device 1 according to the present invention. A pre-transfer position 2 for the rectangular steel material W is provided slightly to the left of the center of FIG. The post-transfer position 3 of the rectangular steel material W is provided slightly to the right of the center of FIG. Accordingly, the transfer device 1 traverses the rectangular steel material W held at the pre-transfer position 2 to the post-transfer position 3 (from left to right), and in the process of traverse, the rectangular steel material W W is turned 45 ° around the center of the cross section of W.
[0021]
In this embodiment, the square steel material W is a square billet rolled by a billet rolling mill (not shown), and the billet rolling machine is installed on the lower side of FIG. It is assumed that the arrow X is the direction in which the rectangular steel material W is carried in. Further, a heat preservation furnace (not shown) is installed on the upper side of FIG. The rectangular steel material W after being laterally fed to No. 3 is dispensed toward this heat retaining furnace (see arrow Y).
As is apparent from such circumstances, since the rectangular steel material W becomes so large that its total length slightly exceeds 10 meters, the above-mentioned pre-transfer position 2 is set to receive a large number (18). The rollers 5 are arranged by arranging them in a vertical line at a predetermined interval (a pitch of 1500 mm) from each other. Similarly, the transfer position 3 described above also includes a large number (18) of transfer rollers. 6 are arranged in a vertical line at a predetermined interval (a pitch of 1500 mm).
[0022]
Accordingly, the transfer apparatus 1 according to the present invention also includes the transfer rollers 6 between the pre-transfer position 2 and the post-transfer position 3 between the receiving rollers 5 aligned side by side (adjacent) with each other. As a unit, the apparatus components 1a arranged in a state of connecting them to each other are provided vertically as many as the number of the receiving rollers 5 and the transfer rollers 6 arranged vertically, so that the transfer apparatus 1 as a whole is It is configured.
Of course, the number of units of the device structure 1a constituting the transfer device 1 can be changed according to the embodiment, and is not limited at all. The case (for example, when the square steel material W is extremely short or the like) In some cases, the transfer device 1 according to the present invention can be constituted by only one unit of the device structure 1a.
[0023]
In the present embodiment, the receiving roller 5 at the above-described pre-transfer position 2 employs a V roller having a V-shaped groove bottom, and each of the receiving rollers 5 is driven by its own motor 7. There is something to be done. The transfer roller 6 at the post-transfer position 3 is provided with a plurality (four) of flat roller grooves (refer to reference numeral 6a in FIG. 1 and the like) at the bottom of the groove, which rotate integrally. These transfer rollers 6 are driven by a unique motor 8.
[0024]
Therefore, at the position 2 before the transfer, the square steel material W is held in an obliquely upright state (45 ° turning state), and at the position 3 after the transfer, the square steel material W passes through the 45 ° turning. Is held in a flat state.
As shown in FIGS. 1 to 3, the transfer device 1 (device structure 1 a) includes a traverse rail 10 provided between a pre-transfer position 2 and a post-transfer position 3, and the traverse rail 10. A carriage 11 that is movable along 10; a carriage driving means 12 that reciprocates the carriage 11 between a pre-transfer position 2 and a post-transfer position 3; , A cam rail 14 and a forced swing guide 15 provided along the side of the traverse rail 10, and an elevating means 16 for supporting the traverse rail 10.
[0025]
As shown in FIGS. 5 and 6, the transport vehicle 11 has a vehicle body 20 having a trapezoidal shape in which the side surface shape is divergent. The wheels 21 run on the lateral feed rail 10.
A wrapping drive means 22 such as a chain forming an endless (see FIG. 1) including the vehicle body 20 is connected to the front and rear flared protruding end portions of the vehicle body 20. The wrapping drive means 22 is wrapped around a pair of front and rear wheels 24 and 25 provided on a rail frame 23 supporting the lateral feed rail 10.
[0026]
One of the wheels 25 can be driven to rotate, so that the carriage driving means 12 is configured. In the carriage driving means 12, the rotating shaft 26 of the driving-side wheel 25 is connected in series as a whole of the transfer device 1 (to all the device components 1a) as shown in FIG. This is rotationally driven by one motor 27. Therefore, the moving direction, the moving speed, and the moving timing of the transport carriage 11 are kept completely the same between all the device components 1a.
[0027]
For this reason, by rotating the motor 27 forward or backward in the carriage driving means 12, the carriage 27 moves back and forth between the pre-transfer position 2 and the post-transfer position 3 on the transport vehicle 11. In the post-transfer position 3, the transfer roller 6 can be stopped at one of the four stop positions corresponding to each roller groove 6a at each time. it can.
Each stop position of the transport vehicle 11 at the pre-transfer position 2 or the post-transfer position 3 can be determined with high accuracy based on a position detection sensor (not shown) provided on the side of the lateral feed rail 10 or the transport vehicle 11. It is controlled.
[0028]
The steel support 13 is sandwiched inside the vehicle body 20 of the transport vehicle 11, and is supported by a support shaft 29 provided near the upper end of the vehicle body 20, in the front-rear direction along the moving direction of the transport vehicle 11. It swings in the direction. A bearing 30 such as a bush is inserted through the support shaft 29.
As shown in FIG. 7, a V-shaped support surface 32 is formed on the upper surface of the steel support 13 so that the upright surface 32a and the flat surface 32b intersect at 90 °. The face 32 can support two adjacent side faces of the rectangular steel material W. The flat surface 32b is formed longer than the upright surface 32a.
[0029]
Further, the steel support 13 is provided with a lower extension 35 extending in an inverted triangular shape below the shaft hole 34 through which the support shaft 29 and the bearing 30 pass. Is provided with a mounting shaft hole 36.
The mounting shaft holes 36 are provided for penetrating and holding a mounting shaft 37 that penetrates the vehicle body 20 from the steel support 13 and protrudes to the left and right sides. A contact 39 made of a disk-shaped roller is rotatably held via a bearing 40 such as a bush. The mounting shaft 37 projects further to the left and right sides than the holding portion of the contact 39.
[0030]
The vehicle body 20 of the transport vehicle 11 is provided with a shaft through-hole 42 through which the mounting shaft 37 passes. The shaft through-hole 42 does not hinder the swing of the steel support 13. Are formed as arc-shaped long holes centered on the mounting position of the support shaft 29.
The steel support 13 has a state in which the V-shaped support surface 32 has its upright surface 32a and the flat surface 32b oriented vertically and horizontally, respectively, and the upright surface 32a and the flat surface 32b are tilted at 45 ° from a vertical surface or a horizontal surface. It is supposed to swing in the range of the state in which it is made to be in a state of being made to move. Then, in a normal state, the upright surface 32a and the flat surface 32b maintain a state of being vertical and horizontal.
[0031]
This is because the flat surface 32b is longer than the upright surface 32a, the lower extension 35 is provided below the support shaft 29, and the lower extension 35 has a mounting shaft 37 and a contact 39. Is based on the weight balance based on the point provided.
Under this normal condition, the steel support 13 is stopped by a stopper 43 provided in the vehicle body 20 of the carrier 11. The stopper 43 is capable of adjusting the degree of movement of the contact stop position by inserting and removing shims 44 having different thicknesses into and out of a mounting portion with respect to the vehicle body 20, whereby the V-shaped support surface 32 (flat surface 32 b) can be adjusted. The height position can be finely adjusted.
[0032]
At least on the right and left sides of the V-shaped support surface 32 on the upright surface 32a side, overhanging pieces 45 for surface enlargement are provided. In the case where it is necessary to support a rectangular steel material W shorter than the total length of the transfer device 1 (the distance between the device components 1a disposed at the upper and lower ends in FIG. 4), FIG. As shown in FIG. 4, at least at the upper and lower ends of the apparatus structure 1 a in FIG. 4, the overhang length is set to the V-shaped support surface 32 (both the upright surface 32 a and the flat surface 32 b) of the steel support 13. It is preferable to provide the overhanging pieces 46 and 47 having a large size.
[0033]
That is, by providing such overhanging pieces 46 and 47, it is possible to reliably support the rectangular steel material W and prevent its drooping (bending deformation caused by hot steel exceeding 1000 ° C.).
As shown in FIG. 1, when the transport carriage 11 is stopped corresponding to the pre-transfer position 2, the cam rail 14 contacts the contact 39 as a part of the steel support 13 from below. It is provided on the side of the lateral feed rail 10 (the upper surface of the rail frame 23) at a position where it can be brought into contact (that is, the contact 39 can ride on).
[0034]
As shown in FIGS. 9 to 13 in an enlarged manner, the cam rail 14 has an inclined surface 14a and a flat surface 14b following the top of the cam rail 14, and the contact 39 of the steel material support 13 has a flat surface 14b. At the time of reaching and being lifted (at the time of climbing), the steel support 13 holds the upright surface 32a and the flat surface 32b of the V-shaped support surface 32 in a state of being inclined by 45 ° with respect to the vertical surface and the horizontal surface, respectively. It is made to let.
Needless to say, even if the transport trolley 11 moves within a range in which the contact 39 of the steel support 13 rolls on the flat surface 14b, the steel support 13 does not swing, and therefore the upright surface 32a and the The state of the flat surface 32b is unchanged.
[0035]
Further, when the carrier 11 moves from the pre-transfer position 2 to the post-transfer position 3, the contact 39 of the steel support 13 rolls down on the inclined surface 14a. Since the lifting height gradually decreases, the steel support 13 swings, and the upright surface 32a and the flat surface 32b of the V-shaped support surface 32 become vertical and horizontal, respectively (that is, the steel support 13 is in a normal state). Return to).
When the transport vehicle 11 moves from the post-transfer position 3 to the pre-transfer position 2, the contact 39 of the steel support 13 rides on the inclined surface 14 a, conversely, As a result, the lifting height of the contact 39 gradually increases, so that the steel support 13 swings, and the upright surface 32a and the flat surface 32b of the V-shaped support surface 32 are 45 degrees away from the vertical surface and the horizontal surface, respectively. ° Return to the tilted state.
[0036]
The height of the cam rail 14 can be adjusted by inserting and removing spacer members 50 (such as shims) having different thicknesses into and out of a portion to be installed along the side of the lateral feed rail 10 (the upper surface of the rail frame 23). I have.
In addition, as such a cam rail 14, various types of cam rails having different inclination angles on the inclined surface 14a are prepared, and if these can be replaced as needed, it is necessary to swing the steel support 13. Thus, the moving distance of the transfer carriage 11 can be shortened, the distance between the receiving roller and the transfer roller can be shortened, and the space can be saved and the time cycle can be shortened.
[0037]
The forcible swing guide 15 is closer to the post-transfer position 3 than the position where the steel support 13 and the cam rail 14 are in contact with each other during the movement of the carrier 11 from the pre-transfer position 2 to the post-transfer position 3. , More specifically, at a position after the contact 39 of the steel support 13 has moved from the flat surface 14b of the cam rail 14 to the inclined surface 14a, stands up from the side surface of the rail frame 23 in the transverse feed rail 10. It is provided in a state.
At the upper end of the forcible swing guide 15, a bent portion 52 that is bent like a hook so as to cover the upper side of the rail frame 23 is provided. The bent portion 52 has an inclination such that the position closer to the position 2 before transfer is higher and the position closer to the position 3 after transfer is lower.
[0038]
In the bent portion 52, the height of the high portion near the pre-transfer position 2 and the low portion near the post-transfer position 3 is such that the contact 39 of the steel support 13 rolls on the inclined surface 14 a of the cam rail 14. When it is within the range, the contact 39 is held so as to rub against the upper surface of the mounting shaft 37 holding the contact 39 or leave a small gap so as not to rub. Therefore, the angle of inclination of the bent portion 52 is substantially the same as the angle of inclination of the inclined surface 14 a of the cam rail 14.
For this reason, in the process of moving the carriage 11 from the pre-transfer position 2 to the post-transfer position 3, the contact 39 of the steel support 13 is Although the steel support 13 swings toward the normal state by rolling down on the inclined surface 14a, the steel support 13 may not swing sufficiently due to poor rotation of the support shaft 29 or the like. Even in this case, the steel support 13 is reliably rocked while the upper surface of the mounting shaft 37 is pressed against the lower surface of the bent portion 52 of the forced rocking guide 15.
[0039]
That is, the lower surface of the bent portion 52 is a contact guide surface 52a for forcibly swinging the steel support 13 downward.
As shown in FIGS. 1 to 3 and FIG. 14, the elevating means 16 extends in the direction in which the lateral feed rail 10 extends (in the illustrated example, the direction is closer to the pre-transfer position 2, but is closer to the post-transfer position 3). And a forward / backward driving tool 55 installed in the front and rear directions of the lateral feed rail 10 with respect to the rail frame 23. And a pair of link mechanisms 57 that are connected to each other.
[0040]
A hydraulic cylinder such as pneumatic or hydraulic is used as the reciprocating drive 55.
The link mechanism 57 includes a lever shaft 62 rotatably held by a bearing 61 fixed to the base floor 60, and an input hinge 63 and an output hinge fixed to the lever shaft 62 in a V-shaped open state. 64, and a bracket 65 fixed to the lower surface of the rail frame 23 and rotatably connected to the output hinge 64. A connecting rod 56 is rotatably connected to the input hinge 63. ing.
Accordingly, when the forward / backward driving tool 55 moves backward, the connecting rod 56 is retracted toward the pre-transfer position 2 and both the input / output hinges 63 and 64 are pivoted in the rising direction (counterclockwise in FIG. 1), and the rail is thereby moved. When the reciprocating drive 55 moves forward together with the frame 23, the connecting rod 56 is pushed toward the position 3 after the transfer, and the input / output hinges 63, 64 are both folded down. 14 (clockwise in FIG. 14), whereby the lateral feed rail 10 moves down together with the rail frame 23.
[0041]
The reciprocating drive 55 moves upward when the transport vehicle 11 is at the pre-transfer position 2, moves down to the post-transfer position 3 after the transport vehicle 11 is at the post-transfer position 3, and moves down when the transport vehicle 11 is at the post-transfer position 3. It has become.
The vertical movement stroke of the traversing rail 10 accompanying the vertical movement of the lifting / lowering means 16 is such that the steel support 13 moves when the transporting trolley 11 is at the pre-transfer position 2 and the lifting / lowering means 16 is raised. The rectangular steel material W can be scooped up from the pre-loading position 2, and when the carrier 11 is at the post-transfer position 3 and the elevating means 16 is moved down, the steel material support 13 transfers the rectangular steel material W. It is set within a range that can be placed on the post-loading position 3.
[0042]
In the present embodiment, it is assumed that all the device components 1a constituting the transfer device 1 are provided with the lifting / lowering means 16 (in the form having the forward / backward driving tool 55 and the pair of link mechanisms 57). Not. That is, in FIG. 4, as can be seen from the fact that the reciprocating driving tool 55 is provided only in every other device structure 1 a, the elevating means 16 is provided only in every other device structure 1 a. did. However, only the link mechanism 57 is necessarily provided even if there is an apparatus structure 1a without the lifting means 16.
[0043]
In addition, the link mechanisms 57 arranged in the vertical direction (up and down direction in FIG. 4) are connected in series by the lever 62 between all the device components 1a (see FIGS. 2 and 3 as well). See). That is, the lever 62 also serves as a line shaft (interlocking shaft).
By doing in this way, the direction of ascending / descending as the elevating / lowering means 16, the elevating / lowering operation speed, and the elevating / lowering movement timing are maintained completely between all the device components 1a.
[0044]
The operation state of the rectangular steel material transfer device 1 according to the present invention having such a configuration will be described.
First, it is assumed that the rectangular steel material W is carried into the pre-transfer position 2 as indicated by an arrow X from a billet rolling mill (not shown) installed on the lower side of FIG.
At this time, as shown in FIG. 1, the lifting / lowering means 16 has lowered the lateral feed rail 10, and the transport carriage 11 on this lateral feed rail 10 stops corresponding to the pre-transfer position 2. It is assumed that
[0045]
As shown in FIG. 9, when the carriage 11 is stopped at this position, the contact 39 of the steel support 13 rides on the cam rail 14, so that the V-shaped support surface 32 of the steel support 13 is The upright surface 32a and the flat surface 32b are in a state of being inclined by 45 ° with respect to a vertical surface or a horizontal surface. Further, the V-shaped support surface 32 is positioned at a height that does not interfere with (does not reach) the rectangular steel material W supported on the receiving roller 5 at the pre-transfer position 2.
Next, as shown in FIG. 14, the lifting / lowering means 16 ascends to raise the transport trolley 11 together with the traverse rail 10 and is held at the pre-transfer position 2 on the V-shaped support surface 32 of the steel support 13. The square steel material W is scooped up (see FIG. 10). At this time, there is no slippage between the rectangular steel material W and the V-shaped support surface 32 of the steel material support 13, so that the rectangular steel material W is not damaged.
[0046]
Next, the carriage driving means 12 is operated while the lifting / lowering means 16 remains in the ascending operation, that is, while the traverse rail 10 is held at the ascending position, and after the transfer carriage 11 is transferred from the pre-transfer position 2. Move toward position 3.
At this time, as shown in FIG. 11, the contact 39 of the steel support 13 rolls down from the cam rail 14 so that the steel support 13 swings. Even if it does not swing, the mounting shaft 37 of the contact 39 is surely pressed down by the forced swing guide 15, and as a result, the steel support 13 swings reliably.
[0047]
Therefore, the upright surface 32a and the flat surface 32b of the V-shaped support surface 32 of the steel support 13 are vertically and horizontally, respectively. At this time, the flat surface 32b is at a higher level than the partitioning flange 6b provided on the transfer roller 6 at the position 3 after the transfer, and the rectangular steel material is placed flat on the flat surface 32b. It is assumed that W does not interfere with the transfer roller 6.
In this way, the carriage 11 stops at the transfer roller 6 corresponding to the specified roller groove 6a.
[0048]
Next, as shown in FIG. 12, the lifting / lowering means 16 moves down to lower the transport trolley 11 together with the lateral feed rail 10, and the square steel material W held by the V-shaped support surface 32 of the steel material support 13 is removed. The transfer roller 6 is replaced with a predetermined roller groove 6a at the position 3 after the transfer. At this time, no slippage occurs between the rectangular steel material W and the roller groove 6a of the transfer roller 6, and therefore, the rectangular steel material W is not damaged.
Needless to say, the flat surface 32b of the steel support 13 at this time is lowered to a level lower than the roller groove 6a of the transfer roller 6.
[0049]
Thereafter, the carriage driving means 12 is operated while the lifting / lowering means 16 remains in the descending operation, that is, while the lateral feed rail 10 is held at the descending position, and the transport carriage 11 is transferred from the post-transfer position 3. Move toward position 2. Thus, one cycle operation ends.
By repeating such a cycle operation, the square steel material W is transferred to each roller groove 6a of the transfer roller 6 at the post-transfer position 3, or the square steel material W is transferred to each roller groove 6a. Each time, the transfer roller 6 is driven, and the rectangular steel material W is discharged from the post-transfer position 3 toward the heat retaining furnace (not shown) installed on the upper side in FIG.
[0050]
By the way, the present invention is not limited to the above embodiment.
For example, although not shown, a stopper 43 provided in the vehicle body 20 of the carriage 11 to control the normal state of the steel support 13 may be configured to advance and retreat from a mounting portion with respect to the vehicle body 20 by adjusting the screwing degree of the bolt. Good.
In order to adjust the height of the cam rail 14, the spacer member 50 can be inserted into and removed from the installation portion of the lateral feed rail 10 along the road, by using a wedge-shaped spacer 68 using a fluid pressure cylinder 67 as shown in FIG. And a method of adjusting the insertion amount of the wedge-shaped spacer 68 using a rack 70 and a pinion gear 71 that can be driven by a motor as shown in FIG.
[0051]
In these cases, as shown in FIG. 17, it is preferable that the wedge-shaped spacer 68 and the cam rail 14 are fitted to each other so as to prevent the wedge-shaped spacer 68 and the cam rail 14 from coming off from each other. May be provided to obtain further certainty.
In the carriage driving means 12, the winding driving means 22 can be replaced with a wire, a rope, a belt or the like. Further, as the carriage driving means 12, a feed screw mechanism, a push-pull mechanism using a fluid pressure cylinder, or the like can be employed.
[0052]
Although the square steel material has been described as having a square cross section, it is also possible to use a shaped steel material with a cross section of a rectangle, a rhombus, H, L, or the like.
[0053]
【The invention's effect】
