DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for transferring rectangular steel materials.

[0002]

2. Description of the Related Art A steel piece such as a billet or a bloom, or another long steel product having a square cross section (hereinafter, collectively referred to as a "square steel material") is placed at the center of the cross section. Various methods have been proposed as a method of turning the device around 45 °. For example, Japanese Utility Model Application No. 4-113104
In the publication, rollers having truncated cones are arranged so that the small-diameter sides of the truncated cones are arranged in a staggered manner with the transport line interposed therebetween, and the rollers having the truncated cones are arranged on one side of the transport line. An apparatus (hereinafter, referred to as a "first conventional apparatus") in which a roller row can be moved toward and away from a roller row of a truncated cone arranged on the other side is described.

In this first conventional apparatus, a rectangular steel material which is placed flat with respect to a transport line when the roller rows are separated from each other is moved upright (45.degree. State). In Japanese Patent Application Laid-Open No. Hei 7-124622, a mountain-shaped trajectory having both lower ends and a higher middle is provided between two parallel roller lines, and a mounting vehicle can be freely moved on the traverse orbit. 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 transfer destination are set on standby (hereinafter referred to as “second conventional device”). Is described).

In the 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. Then, as the loading cart becomes inclined along the downward slope of the crossing track, the square steel material is turned 45 ° to the V-shaped portion by the taper roller and the flat roller at the roller line of the transfer destination. It is to be delivered as it is. Showa 6
In Japanese Patent Application Laid-Open No. 2-41728, 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 by a separate hydraulic cylinder. A device which is operated simultaneously (hereinafter referred to as a "third conventional device") is described.

In this third conventional apparatus, as a simultaneous operation of a double link mechanism, a square steel material on a V roller (that is, a square steel material is initially in an obliquely upright state) is scooped up to a near side. (Closer to the double 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. JP 11
Japanese Patent Publication No. 139556 discloses that a crossing track is provided between a cradle for mounting a square steel material in a 45 ° oblique standing state and a transfer line provided on the side of the cradle. It is provided so as to be movable, and the loading cart is provided with a loading rod capable of swinging up and down, and at the upper end side of the loading rod, a V-shaped loading portion for loading a square steel material is provided,
Furthermore, a device in which the lower end of the loading rod is wrapped around a pulley device by an endless chain (hereinafter referred to as a "fourth conventional device")
Is described).

In the fourth conventional apparatus, when the transfer carriage is on the cradle side, one of the pulleys in the pulley device is moved away from the other pulley to raise and swing the loading rod, whereby the rectangular steel material is removed from the cradle. The transfer truck is moved laterally to the transport line by driving the pulley device (rotating the pulley), and on the transport line side, the pulley interval of the pulley device is returned to the original (closer) and the loading rod is moved. Oscillates downwardly, whereby the rectangular steel material is sent 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]

In the first conventional apparatus, the rectangular steel material can be turned only by 45 °, but cannot be laterally fed in the direction orthogonal to the longitudinal direction of the rectangular steel material and cannot be raised or lowered. For this reason, the first conventional apparatus is provided with 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 conveying device having a conveying roller groove and a partitioning flange protruding between the conveying roller grooves.

[0008] Further, in the first conventional apparatus, it is not possible to determine whether to turn right or left due to the delicate balance of the square steel material at the time of 45 ° turning, which is disadvantageous in stabilizing the quality. there were. In the second conventional device, the rectangular steel material can be turned 45 ° and traversed, but cannot be moved up and down. For this reason, 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.

Further, in the second conventional apparatus, when the rectangular steel material is transferred from the loading cart to the roller line (the V-shaped portion formed by the taper roller and the flat roller), the rectangular steel material is transferred onto the taper roller. At this time, there is a problem that the square steel material is scratched. In the third conventional apparatus, although the rectangular steel material can be turned 45 ° and traversed, and furthermore, can be raised and lowered when taking out and delivering the rectangular steel material, the take-out position and the delivery position are fixed uniquely. There was a problem. This is because, when there is a request to individually transfer the 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.

Further, in the third conventional apparatus, a separate hydraulic cylinder is 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 the 45 ° turning of the square steel) and the transfer line (after the 45 ° turning of the square steel) 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 conveyance 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 driving device for driving the pulley device (rotating the pulley) are separately required, and are structurally complicated. In addition, there was a problem of an increase in size.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and enables a simple structure to perform 45 ° turning of a square steel member and traverse in a direction orthogonal to a longitudinal direction by a simple structure. Before and after the square steel material can be delivered to the required location (including multiple locations) while ascending and descending, and the overall structure is simpler and more compact. ,
It is still another object of the present invention to provide a rectangular steel material transfer device capable of preventing abrasion or the like from being applied to the rectangular steel material.

[0012]

In order to achieve the above object, the present invention takes 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 position after the transfer, and the traverse rail provided between the position before the transfer and the position after the transfer; A movable carriage, a carriage driving means for reciprocating the carriage between a pre-transfer position and a post-transfer position, and two adjacent rectangular steel members held at the pre-transfer position. It has a V-shaped support surface corresponding to the side surface, and this V-shaped support surface has 45
The steel support, which is provided so as to be swingable with respect to the carrier in the tilting range, and one of the steel supports when the carrier moves between the pre-transfer position and the post-transfer position. A cam rail provided along the side of the traverse rail to push and swing the steel support from one end of the swing range to the other end thereof in contact with the portion.

[0013] With this configuration, the carrier is provided on the carrier only by moving the carrier from the pre-transfer position to the post-transfer position (or vice versa) while moving along the lateral feed rail. A part of the provided steel support abuts on a cam rail provided along the side of the traverse rail and swings, and this swing tilts the V-shaped support surface of the steel support by 45 °. The square steel material supported on the support surface is turned by 45 °. Therefore, in this transfer device,
As a main driving device for enabling both the lateral feeding and the 45 ° turning of the rectangular steel material, only a bogie driving means for moving the transport bogie is required. It is possible to suppress the conversion.

In addition, this configuration is advantageous in that the 45 ° turning of the square steel material can be performed with a very short distance and reliably. Furthermore, the stop position of the transport vehicle 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, the versatility is extremely high. The transverse feed 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 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.

As the elevating means, an advancing / retreating driver installed in the extending direction of the traverse rail, and when receiving an advancing operation from the advancing / retracting driver, lowering the traverse rail and receiving a retreating operation from the advancing / retracting driver. And a link mechanism that raises the traverse rail when the traverse rail moves. 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.

Further, when handling a rectangular steel material having a length 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, if the link mechanism is adopted as described above, synchronization can be ensured only by providing a line shaft (interlocking shaft) in a skewered shape,
Also in this respect, the structure can be simplified and the size can be suppressed. When the transport vehicle is at the post-transfer position, and immediately before the steel material support switches the rectangular steel material to the post-transfer position with the downward movement of the elevating means, V
The height of the mold support surface should be controlled by stopping and hitting one end of the swing range of the steel material support with a stopper provided on the carrier. In addition, it is suitable for ensuring the reliability.

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 moving a spacer member in and out of a portion where the cam rail is installed along the side of the lateral feed rail. By doing so, when scooping the square steel material from the pre-transfer position, it is possible to reliably obtain a state in which the square steel material does not slide with respect to the pre-transfer position or the V-shaped support surface.
There is an advantage that the square steel material does not need to be scratched.

In the process of moving the carriage from the pre-transfer position to the post-transfer position along the side of the lateral feed rail, the post-transfer position is 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 at the position. This forced swing guide is intended to abut a part of the steel support in which the swing failure has occurred, and to supplement the swing to a reliable one. 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.

If the cam rail is replaceable with one having a different inclination angle, the moving distance of the carriage required to swing the steel support can be shortened, and the time cycle can be shortened accordingly.

[0020]

In FIG. 4, a heat retaining furnace (not shown) is installed on the upper side, and the rectangular steel material W after being laterally fed to the post-transfer position 3 is discharged toward the heat retaining furnace (see arrow Y). There is. As is apparent from such circumstances, the square steel material W
Since the length of the receiving roller 5 is so large that the total length thereof slightly exceeds 10 meters, the above-mentioned pre-transfer position 2 is such that a large number (18) of the receiving rollers 5 are separated from each other by a predetermined distance (1500 m).

In response to this, the transfer apparatus 1 according to the present invention also has a position between the pre-transfer position 2 and the post-transfer position 3 between the receiving rollers 5 which are aligned (adjacent) side by side with each other. The unit 1a, which is arranged so as to connect the transfer rollers 6 with each other, is provided as one unit, and is arranged vertically by the same number as the number of the receiving rollers 5 and the transfer rollers 6, so that the whole is transferred. The apparatus 1 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.

In this embodiment, the receiving roller 5 at the pre-transfer position 2 employs a V-roller having a V-shaped groove bottom, and each receiving roller 5 has its own motor. 7 is driven. Also,
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 individual transfer rollers 6 are driven by a unique motor 8.

Therefore, at the position 2 before transfer, the square steel material W
Is held in an inclined standing state (45 ° turning state), and at the post-transfer position 3, the rectangular steel material W is held in a flat state as a state after 45 ° turning. .

As shown in FIG. 5 and FIG.
Has a vehicle body 20 having a trapezoidal shape with a flared side surface. Self-propelled wheels 21 are provided at the lower part of the vehicle body 20 so as to protrude to the left and right sides. It runs on 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 ends of the vehicle body 20.
The wrapping driving 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.

The carriage driving means 12 is constituted by one of the wheels 25 being rotatable. 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 (with respect 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 consistent between all the apparatus components 1a.

Because of this, the truck driving means 1
By rotating the motor 27 forward or backward in 2, the carrier cart 11 can be moved back and forth between the pre-transfer position 2 and the post-transfer position 3. At the post-loading position 3, the transfer roller 6 can be stopped at one of the four stop positions corresponding to the respective roller grooves 6a at each time. The stop positions of the transport vehicle 11 at the pre-transfer position 2 and 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 or the like. It is controlled.

The steel support 13 is sandwiched inside the vehicle body 20 of the carriage 11, and is supported by a support shaft 29 provided near the upper end of the vehicle body 20.
It swings in the front-rear direction along the moving direction of the transport vehicle 11. A bearing 30 such as a bush is inserted through the support shaft 29. As shown in FIG.
The upright surface 32a and the flat surface 32b are 90 °
A V-shaped support surface 32 formed by intersecting with each other is provided, and the V-shaped support surface 32 can support two adjacent side surfaces of the rectangular steel material W. The flat surface 32b is formed longer than the upright surface 32a.

The steel support 13 is provided with a support shaft 29.
A lower extension 35 is provided below the shaft hole 34 through which the bearing 30 penetrates and extends downward in an inverted triangular shape. The lower extension 35 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 composed 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.

The vehicle body 20 of the carriage 11 is provided with a shaft through hole 42 through which the mounting shaft 37 passes. The shaft through hole 42 prevents the steel material support 13 from swinging. It is formed as an arc-shaped long hole centered on the mounting position of the support shaft 29 so that there is no such hole. This steel support 13
The V-shaped support surface 32 has an upright surface 32a and a flat surface 32a.
b are oriented vertically and horizontally, respectively, and the upright surface 32a and the flat surface 32b are set at 45 degrees from the vertical surface and the horizontal surface.
° It is supposed to swing within the range of the tilted state. Then, in a normal state, the upright surface 32a and the flat surface 32b maintain a state of being vertical and horizontal.

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 an attachment shaft 37 The weight balance is based on the point where the contact 39 is provided. Under this normal condition, the steel support 13 is brought into contact with and 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 portion to be attached to the vehicle body 20, whereby the V-shaped support surface 32 (the flat surface 32b) can be adjusted. The height can be adjusted finely.

At least on the right and left sides of the V-shaped support surface 32 on the upright surface 32a side, projecting pieces 45 for surface enlargement are provided.
Is 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 FIG.
Mold support surface 32 (both upright surface 32a and flat surface 32b)
In contrast, it is preferable to provide the overhanging pieces 46 and 47 having a large overhang length.

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 due to hot steel exceeding 1000 ° C.). . As shown in FIG. 1, when the carrier 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 the contact can be made (that is, the contact 39 can ride on).

As shown in FIG. 9 to FIG. 13, 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 support 13 is flat. At the time of reaching the surface 14b and being lifted (at the time of climbing), the steel material support 13 is
The second upright surface 32a and the flat surface 32b are held in a state of being inclined by 45 ° with respect to a vertical surface or a horizontal surface, respectively. Needless to say, the range of the contact carrier 39 of the steel support 13 rolls on the flat surface 14b.
Is moved, the steel support 13 does not swing, so that the state of the upright surface 32a and the flat surface 32b of the V-shaped support surface 32 is unchanged.

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,
As a result, the lifting height of the contact 39 gradually decreases, so that 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 (ie, (The steel support 13 returns to the normal state.)
Become like 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.

The cam rail 14 is provided for the lateral feed rail 10.
The height 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 road (the upper surface of the rail frame 23). In addition, as such a cam rail 14, an inclined surface 14a
By preparing various types having different inclination angles and making them replaceable as necessary, it is possible to shorten the moving distance of the carrier 11 required to swing the steel support 13. Thus, the distance between the receiving roller and the transfer roller can be shortened, so that the space can be saved and the time cycle can be shortened.

The forcible swing guide 15 is provided on the carrier 11
In the process of moving from the pre-transfer position 2 to the post-transfer position 3, a position closer to the post-transfer position 3 than the position where the steel support 13 and the cam rail 14 abut, more strictly speaking,
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, the steel support 13 is provided so as to rise from the side surface of the rail frame 23 in the lateral feed rail 10. At the upper end of the forced swing guide 15, a bent portion 52 is provided which is bent in a hook shape so as to cover the upper side of the rail frame 23. 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.

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 is
When it is within the range of rolling on the inclined surface 14a, it 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 The steel support 13 swings toward the normal state by rolling down on the inclined surface 14a.
When the steel support 13 does not swing sufficiently due to poor rotation or the like, the upper surface of the mounting shaft 37 is fixed to the lower surface of the bent portion 52 in the forced swing guide 15. It will be surely rocked while being held down.

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 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 the 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.

As the forward / backward drive 55, a fluid pressure cylinder such as an air pressure or a hydraulic pressure is used. 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,
It has 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. Therefore, when the reciprocating drive 55 moves backward, the connecting rod 56 is retracted toward the pre-transfer position 2 and the input / output hinges 63, 64 are both raised (FIG. 1).
Of the traverse rail 10 together with the rail frame 23, and conversely,
When the reciprocating drive 55 moves forward, the connecting rod 56 is pushed toward the position 3 after the transfer, and the input / output hinges 63 and 64 are pivoted in a direction to lie down (clockwise in FIG. 14). The lateral feed rail 10 descends.

The advance / retreat driving tool 55 moves up when the transport vehicle 11 is at the pre-transfer position 2, moves to the post-transfer position 3, and then moves when the transport vehicle 11 is at the post-transfer position 3. It is designed to move downward. The vertical movement stroke of the traverse rail 10 accompanying the vertical movement of the lifting / lowering means 16 is as follows.
When the transport trolley 11 is at the pre-transfer position 2 and the elevating means 16 is moved up, the steel support 13 is made to be able to scoop up the square steel W from the pre-transfer position 2 and the transport trolley 11 When the lifting / lowering means 16 is moved down at the post-transfer position 3, the steel material support 13 is set within a range in which the rectangular steel material W can be replaced at the post-transfer position 3.

In this embodiment, all the device components 1a constituting the transfer device 1 are provided with the elevating means 16 (in the form having the reciprocating drive 55 and a pair of link mechanisms 57). And 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 / lowering 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.

Further, between all the device components 1a,
The link mechanisms 57 arranged in the vertical direction (the vertical direction in FIG. 4) are connected in series by their levers 62 (see also FIGS. 2 and 3). 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 means 16, the elevating / lowering operation speed, and the elevating / lowering movement timing are maintained completely between all the device components 1a.

The operation of the rectangular steel material transfer apparatus 1 according to the present invention having the above-described structure will be described. First, as shown by an arrow X, a square steel material W is transferred from a billet rolling mill (not shown) installed at the lower side of FIG.
Suppose that it was carried in. At this time, as shown in FIG. 1, the lifting / lowering means 16 keeps the lateral feed rail 10 in a lowered state,
Further, it is assumed that the transport vehicle 11 is stopped on the lateral feed rail 10 corresponding to the pre-transfer position 2.

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 steel support 1
The V-shaped support surface 32 has an upright surface 32a and a flat surface 3a.
2b is inclined 45 ° with respect to a vertical plane or a horizontal plane. The V-shaped support surface 32 is located at the position 2 before transfer.
Is positioned at a height that does not interfere with (do not reach) the rectangular steel material W supported on the receiving roller 5. Next, FIG.
As shown in FIG. 4, the lifting / lowering means 16 moves upward to raise the transport carriage 11 together with the traverse rail 10, and the steel support 1
The square steel material W held at the pre-transfer position 2 by the V-shaped support surface 32 of FIG. 3 is scooped up (see FIG. 10). At this time, no slippage occurs between the rectangular steel material W and the V-shaped support surface 32 of the steel material support 13, and therefore, the rectangular steel material W is not damaged.

Next, the carriage driving means 12 is operated while the lifting / lowering means 16 is in the ascending operation, that is, while the lateral feed rail 10 is held at the ascending position, and the transport carriage 11 is moved from the pre-transfer position 2. After the transfer, it is moved toward position 3. At this time, as shown in FIG.
9 rolls off the cam rail 14 so that the steel support 13 swings. Even if the steel support 13 does not swing by itself, the mounting shaft 37 of the contact 39 may be used. Is forcibly pressed down by the forced swing guide 15, and as a result, the steel support 13 swings reliably.

Therefore, the V-shaped support surface 32 of the steel support 13
The upright surface 32a and the flat surface 32b are in a vertical and horizontal state, respectively. At this time, the flat surface 32
b is higher than the partitioning flange 6b provided on the transfer roller 6 at the position 3 after the transfer, and the square steel material W which is placed flat on the flat surface 32b interferes with the transfer roller 6. Will not be done. In this way, the carriage 11 stops at the transfer roller 6 corresponding to the specified roller groove 6a.

Next, as shown in FIG.
The lowering operation lowers the transport trolley 11 together with the traverse rail 10 to transfer the rectangular steel material W held on the V-shaped support surface 32 of the steel material support 13 to a predetermined roller of the transfer roller 6 at the post-transfer position 3. Replace with the groove 6a. At this time, the square steel material W and the roller groove 6 of the transfer roller 6
a does not occur between the rectangular steel material W
Will not be scratched. 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.

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 lowered position, and the transport carriage 11 is moved from the post-transfer position 3. After the transfer, it is moved to 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 paid out from the post-transfer position 3 toward the heat retaining furnace (not shown) installed on the upper side in FIG.

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 by adjusting the screwing degree of the bolt from a mounting portion to the vehicle body 20. Good. In the cam rail 14,
As a method of taking the spacer member 50 in and out of the installation portion of the lateral feed rail 10 with respect to the roadside for the height adjustment, the insertion amount of the wedge-shaped spacer 68 is adjusted using a fluid pressure cylinder 67 as shown in FIG. Figure 16
The method of adjusting the insertion amount of the wedge-shaped spacer 68 using the rack 70 and the pinion gear 71 that can be driven by a motor as shown in FIG.

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 out of each other. Further reliability may be obtained by providing the side guard 72 as well. In the carriage driving means 12, the winding driving means 22 can be replaced with a wire, a rope, a belt or the like. Also,
As the carriage driving means 12, a feed screw mechanism or a push / pull mechanism using a fluid pressure cylinder may be employed.

Although the square steel material has been described as having a square cross section, it is also possible to use a square steel material having a cross section such as a rectangle, a rhombus, or H or L.

[0053]

As is apparent from the above description, in the rectangular steel material transfer apparatus according to the present invention, the rectangular steel material can be turned 45 ° and traversed in a direction perpendicular to the longitudinal direction by a simple structure. In addition, before and after the lateral feed, the rectangular steel material can be delivered to a required location (including a plurality of locations) while ascending and descending. And, even with this overall configuration, the structure is simple and it is possible to suppress an increase in size, and it is possible to prevent abrasion or the like from being applied to the square steel material.
