DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer method and a transfer apparatus used for transferring a shaped steel produced in a rolling mill or the like from a supply position such as a pile bed to a predetermined stocking place. It is.

[0002]

2. Description of the Related Art Generally, several steel bars are rolled in a rolling mill to produce products, which are usually nested together in a pile bed or the like, bound together by wires, and transported to a stock yard (stock yard, etc.). Is done.

Conventionally, the transport is performed as shown in FIG. That is, the bundled shaped steel (steel material X) is directly placed on the roller table 90 on which the plurality of rotating rollers 91 are arranged, and the steel material X is fed by rotating part or all of the rollers 91. As the wire W for binding, a steel wire having a diameter of about 5 mm is generally used.

[0004] When conveying not only shaped steel in a rolling mill, but also steel materials, generally, steel materials supplied from a supply position are bound at a binding position, and then, the steel materials are supplied to a predetermined stocking site until the delivery position. As in the case of No. 6, the sheet is conveyed by rotating rollers. Since the role of the roller table is to exclusively feed the steel material from the supply position to the payout position, the table is configured as a single linear transport path connecting the supply position and the payout position. The technology related to the product transport is described in Japanese Patent Publication No. 54-32223.

[0005]

When the steel material X is fed as shown in FIG. 6, there is an inconvenience that the steel material X and the roller 91 come into contact with each other and are rubbed, thereby damaging the surface of the steel material X. Also, each time the wire W binding the steel material X passes over each roller 91, the wire W hits the roller 91 or the steel material X moves up and down and strikes the upper surface of the roller 91, so that considerable noise is generated. Occur. Steel material X of wire W
It is not preferable that the wire W tends to be loosened because the roller 91 straightens the portion passed under the wire W.

An object of the present invention is to provide a means capable of smoothly transporting a steel material from a predetermined supply position to a dispensing position without damaging the surface and suppressing noise generation.

[0007]

A steel material according to claim 1.
First, the transport equipment of a) has a transport platform (cart or pallet) on which steel can be placed.
Etc. are included in this transport table) and b)
And c) a drive to move and stop the carriage along the path.
Means and - are arranged. Further, d) within the transport path of the b), the turning point of the conveying table
And transport the rail (that is, with rails, rotating rollers, etc.)
Where the path to move the cradle) is parallel and
The trajectory changing means for transferring the transfer table between the tracks
And e) transported to a frame that can be moved up and down by an elevating mechanism.
The support that can support the platform can be moved horizontally between the above orbits.
And the horizontal movement
Connected to its support to drive
With the with the track changing means - and also characterized in that
I do.

[0008] In the transport apparatus, the steel placed on the carrying table above a), and the upper path b) in that state from <br/> supply position by driving means c) to the bundling position and dispensing position the transport Since the steel material is transported together with the table , the surface of the steel material does not rub against the rollers or the like. That is, since the steel material is in contact only with the transfer table and does not move relative to the transfer table, the surface of the steel material is not rubbed during the transfer and scratches cannot be generated. If the legs supporting the steel material on the carrier are formed discontinuously at intervals in the longitudinal direction of the steel material, the wire can be easily wound around the steel material, and the bundling operation at the binding position can be facilitated.

[0009] The fact that the steel material rests on the carrier and does not cause relative movement therewith also has the advantage of reducing noise and preventing loosening of the binding. Although the steel material is bound by a wire or the like, the wire or the like does not move over any part of the carriage during the transportation and does not come into contact with anything other than the carriage, and therefore, as shown in FIG. No noise is caused by the wire.
Further, since the wire or the like does not climb over anything, the portion passed under the steel material is not stretched, so that the wire or the like cannot be loosened.

According to the first aspect of the present invention, there is provided the transport device according to the above b).
Along , the transport table is re-circulated from the supply position to the supply position via the binding position and the payout position,
It can be said that the transfer efficiency is also excellent. When transporting steel using a transport table, unlike when transporting steel directly on a roller table or the like, the process of returning the transport table to the original supply position after lowering the steel at a predetermined dispensing position Is required. However, if the path of the transfer table is made into a single line connecting the supply position and the dispensing position like the roller table in the conventional transfer method, and the transfer table is reciprocated,
Until the transfer table returns to the supply position, another transfer table cannot be sent to the payout position, resulting in low transfer efficiency. In that regard, if you make the carrier go around as above ,
Put multiple transport tables on the route and move them at the same time,
It is also possible to carry out the transportation efficiently and smoothly.

[0011]

[0012]

[0013]

[0014] A transport path for rotating a long transport table as in b) is usually a closed-loop path by connecting it with a curve having a certain radius or more. Sites such as factories may not be used efficiently. When connected with a curve, the transport path expands outside and draws a large closed loop, so the path tends to pass through unnecessary places, and it is not easy to set the supply position and payout position in the desired places. is there. However, in the case of this transfer apparatus of claim 1 , since it has the configuration of the above d), it is possible to pass the transfer path only to a necessary place without making it a large loop, and it is possible to set up a site by freely setting a supply position and the like. Enables efficient use. In a certain part of the route, if two orbits with opposite directions of movement of the carriage are brought close to each other in parallel, and the part is turned as a turning point based on d), and the carriage is transferred between the tracks. This is because the transfer table can be turned 180 ° at the narrow turning point provided with the trajectory changing means without forming a long curve as described above. If the turning points having the trajectory changing means as in d) are provided at two separate points (both ends) as shown in FIG. 1 (a), for example, it passes through an unnecessary place only by two approaching paths. It is also possible to configure an extremely compact recirculating transport path that does not require such a configuration.

It should be noted that there is no particular difficulty in transferring the transfer table between the tracks by the configuration d) because the two tracks are approaching in parallel. Since the two orbits are parallel, the transfer table need only be moved in parallel without turning, etc. In addition, since they are close to each other (approximately within a few meters), the required moving distance is small. is there. It is needless to say that the surface of the steel material is not damaged during the transfer, since the steel material remains on the same carrier.

[0016]

In the trajectory changing means of the above e), the support incorporated in the frame moves up and down together with the frame by the elevating mechanism, and the rollers provided between the frame and the frame and the above-mentioned driving source act on the support. It moves relative to the frame so that it moves horizontally between the two tracks. Therefore, when the carriage comes on the support, first raise the support together with the frame to support and lift the carriage with the support, and then horizontally move the support to just above the other track. By carrying the carrier up to and lowering the support with the frame,
As described in d), the transfer table can be transferred between the two tracks. Since the vertical movement and the horizontal movement are performed separately, there are advantages that each operation can be performed reliably and that the degree of freedom in setting the movement distance is high.

According to a second aspect of the present invention, in the above-described transport apparatus, f) a cushioning material (rubber, FRP, or the like) is arranged at a contact portion between the transport table and the transport path (track).

In the case of the apparatus according to the second aspect in which the cushioning material is arranged as described above, the noise due to the movement of the transfer table such as when transferring the steel material is further reduced. Although there is no noise due to the steel binding wires as described above in the apparatus of the first aspect , it is inevitable that some noise is generated as the carrier comes into contact with the transport path when moving. But this f)
In the case of the apparatus according to the second aspect , the shock and vibration generated when the transfer table and the transfer path come into contact with each other are attenuated by the buffer, so that the noise is extremely low. Note that the configuration of the above f) includes a case where a part of the transfer table or the transfer path (for example, wheels, rollers or rails) serving as the contact portion is formed of a metal having a vibration damping property such as a vibration-proof alloy. It is.

[0020]

1 to 3 show an embodiment of the present invention. 1 (a), (b) and (c) are drawings showing the outline of a steel material transfer system in a section rolling mill, and FIGS.
Is a detailed view taken along the line II-II in FIG. 1 (a), and FIG.
FIG. 3 is a detailed view taken along the line III-III in FIG.

The conveying system shown in FIG. 1 carries out a rolled steel material X (H-section steel) from a pile bed A, binds a plurality of wires together by a wire W in a tying machine C, and then stocks the material. They are transported until they are placed in the yard (stock field) F. As shown in the figure, the stockyard F is divided into a plurality of sections, and those having a certain size are stocked in a certain section.

As shown in FIGS. 1 (b) and 1 (c), in this transport system, a steel material X is transported on a transport table 10. The carrier 10 has a gate-shaped leg 11 supporting a steel material X formed at a plurality of positions on a long frame 12 at intervals, and a guide rail 13 is attached to a lower portion of the lower portion of the frame 12. is there. The transfer table 10 is mounted on rollers 21 and 22 arranged as a transfer path 20 with the rail 13 in contact therewith. The transport table 10 travels in the longitudinal direction as the rollers 21 and 22 rotate. One roller 21 has a flange on both sides, and the rail 13 on one side enters between the flanges, so that the transfer table 10 does not come off from the transfer path 20. As shown in FIG. 1B, the rollers 21 and 22 are connected to a driving unit 30 including a motor and the like, and are driven to rotate so that the carrier 10 travels back and forth. Since the steel material X is not placed directly on a roller or a drum and conveyed, the surface (lower surface) of the steel material X is not damaged, and noise caused by the wire W passing over the roller or the like is also reduced. There is no loosening of the wire W itself.

The transport path 20 is not of the reciprocating type but is shown in FIG.
It is a revolving type as shown in the figure. That is, the transport table 10
Can return to the original position via a necessary portion by always traveling in a fixed direction along the transport path 20. Necessary places include a supply position B where the steel material X is placed on the carrier 10 from the pile bed A, a binding position D where the steel material X is bound by the binding machine C, and a predetermined section in the stock yard F. Unloading position E where steel X is lowered
It is. Since the transport path 20 is formed in a circular manner as described above and the traveling of the transport table 10 is limited to one direction, the transport efficiency is high. That is, unlike the case of the reciprocating type, another transfer table 1 on which the steel material X is placed even before the empty transfer table 10 in which the steel material X has been unloaded at the payout position E returns to the supply position B.
0 can be sent from the supply position B to the payout position E, so that a plurality of sets of transfer tables 10 can function simultaneously on the transfer path 20 as shown in the figure. The transfer table 10 may be run one by one. However, when a long steel material X is placed on the transfer table 10, the two tables may be connected to each other and run.

The supply position B shown in FIG.
, So that the transfer table 1
It is supposed that the steel material X is to be put on top of zero. Supply means 40
Has the following configuration. That is, the lifting frame 41 is provided so as to be able to change the height by having the lifting mechanism 42, and the supporting frame 44 on which the steel material X (three to be later bound) can be placed is transported along the lifting frame 41. The table 10 is arranged so as to be able to move horizontally in a direction perpendicular to the longitudinal direction. The elevating frame 41 has a main part made of a channel steel so as to accommodate a rotating roller 45 for facilitating the horizontal movement of the support frame 44, and an elevating mechanism 42 including a rotating plate 42a is arranged at a plurality of locations on the bottom thereof. ing. As shown in the drawing portion of FIG. 2, the rotating plate 42a is
b, it is attached so as to be able to oscillate within a certain angle range around it, and is connected to a rod 42c via a pin provided below the support shaft 42b, so that the height is substantially the same as that of the support shaft 42b. It is connected to the lifting frame 41 via the provided pin. The rod 42c is a substantially horizontal one that connects the rotating plates 42a as a pair, and the two rotating plates 42a are connected to one hydraulic cylinder (not shown) via the rod 42c.
Connected to On the other hand, another hydraulic cylinder 46c is connected to the support frame 44 whose horizontal movement is facilitated by the rotating roller 45 via a push-pull rod 46a and a lever 46b as a driving source 46 in the horizontal direction. When the hydraulic cylinder of the elevating mechanism 42 is expanded and contracted, the rotating plate 42a swings and the elevating frame 41 together with the support frame 44.
The hydraulic cylinder 4 of the drive source 46
By expanding and contracting 6c, the support frame 44 can be moved horizontally along the elevating frame 41.

Therefore, the three steel materials X are gathered together in the piled bed A, and they are densely stacked as shown in FIG.
Then, the supply means 40 transfers the steel material X onto the transfer table 10 stopped at the supply position B facing the bed A as follows. That is, the lifting frame 41 is raised from the position shown by the solid line in the drawing, and the steel material X is supported by the support frame 4.
4, the hydraulic cylinder 46c is contracted, the support frame 44 is moved rightward in the figure, and the lifting frame 41 is lowered there (see the phantom line in the figure), whereby the steel material X supported by the support frame 44 is moved. It is deposited on the carrier 10. Steel X from Piling Bed A to Carrier 10
Is performed by the supply means 40 in this manner,
When using an overhead crane (not shown) or the like in a factory, troublesome staking work or the like is not required. Since the overhead crane and the like are not used exclusively, the efficiency of other work in the same factory can be improved. The movement of the steel material X in the pile bed A until it reaches the supply position B is performed by the pusher A.
2 and an extruding table A3 which is moved back and forth by a rod A4.

At the binding position D shown in FIG.
As described above, a set of three steel materials X placed on the transfer table 10 is automatically bound by the binding machine C. Binding machine C
Among them, means for carrying out the binding work itself, that is, a means for gathering three steel materials X in the width direction and a method for hanging and wrapping a wire W around the steel material X, cutting it in place, and twisting the ends. Are arranged. Carrier 10
Since the legs 11 supporting the steel material X are spaced apart in the longitudinal direction of the carrier 10, the wire W is wound around the steel X while the carrier 10 is stopped as described above. There is no particular problem. Since the wound wire W does not hit the rollers 21 and 22 while the steel material X is transported by the transport system of FIG.
There is almost no change in the united state due to.

In order to lower the steel material X from the transfer table 10 to one section of the stock yard F, payout means 50 shown in FIG. 2 is disposed at each payout position E provided for each section. The dispensing means 50 is also basically configured in the same manner as the supply means 40, and has a lifting mechanism 52 which can change the height and has a supporting frame on which the bound steel material X can be placed. The frame 54 is incorporated so as to be horizontally movable in a direction perpendicular to the longitudinal direction of the carrier 10.
The lifting frame 51 is located in the stockyard F,
The channel roller is used for the main part, and the rotating roller 55 of the support frame 54 is accommodated inside the channel steel. Lifting mechanism 52
A plurality of sets including a rotary plate similar to the elevating mechanism 42 in the supply means 40 are arranged at the bottom of the elevating frame 51. By swinging the plurality of rotating plates by the hydraulic cylinder 52d and the rod 52c, the lifting frame 51 connected to the rotating plates can be moved up and down. A driving source 56 for horizontally moving the support frame 54
As the lever 5 operated by the hydraulic cylinder 56c.
6b is connected to the support frame 54 via a link 56a.

When the conveyor 10 loaded with the bound steel material X stops at the payout position E facing a predetermined section of the stock yard F, the payout means 50 unloads the steel material X as follows. First, the above-described hydraulic cylinder 56c
The support frame 54 is horizontally moved to the position indicated by the imaginary line in FIG.
By raising the supporting frame 54 together with the lifting frame 51 by 2, the steel material X is supported by the supporting frame 54. Subsequently, the support frame 54 is horizontally moved again to carry the steel material X to the right in the drawing, and then the support frame 54 is lowered together with the elevating frame 51, whereby the steel material X can be lowered to the stock yard F. The advantage that the dispensing means 50 streamlines the unloading of the steel material X and eliminates the occupation of the overhead crane or the like is the same as that of the supply means 40. The steel material X dropped to the stockyard F
Is sent to the vicinity of a shipping port (not shown; right side in FIG. 2) by a chain conveyor F1 or the like.

Although the transport path 20 for transporting the transport table 10 is of a revolving type as described above, it does not have a general closed loop path. In the case of a closed loop, it is necessary to provide a curve with a large radius of curvature in order to change the transfer direction of the transfer table 10, and the closed loop becomes large and the area required for laying becomes enormous. As shown in FIG. 1 (a), two orbits 2 approached
0a and 20b and turning points 25 provided at both ends thereof. Each of the tracks 20a and 20b formed by a pair of rollers 21 and 22 is
Are set to be opposite to each other (each direction indicated by an arrow in the drawing), and are arranged in parallel so as to be close to each other so that the interval between the center lines becomes 1500 mm. At the turning point 25, there is provided a track changing means 60 for transferring the transfer table 10 between the tracks 20a and 20b whose transfer directions are opposite to each other. By transferring the carrier 10 between the tracks 20a and 20b by the same means 60, and by reversing the carrier direction accordingly, the traveling direction of the carrier 10 can be substantially changed by 180 °. it can. In this way, since the transfer direction of the transfer table 10 can be changed by 180 ° at one turning point 25 having a small occupied area, a compact orbiting transfer path 20 can be formed by the two adjacent tracks 20a and 20b without drawing a closed loop. It will be.

The trajectory changing means 60 provided at the two turning points 25 is configured as shown in FIG. That is, the means 60 includes a support 64 capable of supporting the transfer table 10 and a frame 61.
The frame 61 can be moved up and down by an elevating mechanism 62, and the hydraulic cylinder 6
The supporting body 64 is horizontally moved by a driving source 66 including a driving means 6c and the like.
0 and the payout means 50 are similar. The support 64 has a plurality of upward pedestals 64a on which the carrier 10 can be placed within the range of the length thereof, and the tracks 20a and 20b.
A plurality of rotating rollers 65 are provided so as to be horizontally movable in a direction perpendicular to the longitudinal direction between them. The frame body 61 is formed mainly of a channel steel so as to accommodate the rotating roller 65 of the support body 64 and serve as a guide for the horizontal movement thereof. As the lifting mechanism 62 of the frame body 61, as shown in the drawing part of FIG. 3, a rotating plate 62a is attached so as to be able to swing around a support shaft 62b fixed on the ground, and the rotating plate 62a is It is connected to the hydraulic cylinder 62d or the rod 62c via one pin and to the frame 61 via another pin. Although the hydraulic cylinder 62d is connected only to one rotary plate 62a, the rod 62c
Since the two rotary plates 62a are connected to each other, the two rotary plates 62a can be simultaneously driven by one hydraulic cylinder 62d. Here, the hydraulic cylinder 62
Since the position of the pin connecting the d or the rod 62c and the rotary plate 62a is located below the support shaft 62b, a large moment is most efficiently applied to the rotary plate 62a by the thrust in the horizontal direction by the hydraulic cylinder 62d or the like. Can be granted. Further, the position of the pin connecting the frame 61 and the rotating plate 62a is substantially the same as the height of the support shaft 62b (substantially right beside the support shaft 62b), so that the frame 61 is substantially vertically oriented. Can be raised and lowered. On the other hand, another hydraulic cylinder 66c is connected as a driving source 66 for the horizontal movement to the support 64 whose horizontal movement is facilitated by the rotating roller 65 via a push-pull rod 66a and a lever 66b. When the hydraulic cylinder 62d of the elevating mechanism 62 is expanded and contracted, the rotating plate 62a swings within a range of 90 ° or less, and the frame 61 together with the support 64 can be raised and lowered. When the cylinder 66c is expanded and contracted, the support 64 can be moved horizontally along the frame 61.

When the carriage 10 reaches the turning point 25 and stops, the trajectory changing means 60 operates as follows.
The transfer table 10 is transferred between a and 20b. First, the support body 64 is raised together with the frame 61 by extending and retracting the hydraulic cylinder 62d of the elevating mechanism 62, and then the carrier 10 is placed on the pedestal 64a and is raised by several tens of mm. In this state, the hydraulic cylinder 66c of the drive source 66 is expanded and contracted to horizontally move the support 64, and the track 20a or the track 20b is moved.
The position of the support 64 and the carriage 10 is moved from right above to the other track. After that, if the hydraulic cylinder 62d is expanded and contracted to lower the support 64 together with the frame 61,
The transfer table 10 that was on the support 64 can be placed on the other track described above. If the position of the support 64 is returned by expanding and contracting the hydraulic cylinder 66c, it is convenient to quickly change the trajectory of the next transfer table 10. According to the trajectory changing means 60, as described above, the orbiting transfer path 20 can be formed compactly, but in addition, the trajectory can be changed smoothly without tilting or vibrating the transfer table 10, Further, there is an advantage that the use of a crane is unnecessary, so that other operations in the factory are not hindered. Since the elevating mechanism 62 and the driving source 66 for horizontal movement are independently provided for the support 64, the vertical movement and the horizontal movement can be reliably performed, and the height and the horizontal movement distance can be freely set. There are also benefits.

FIG. 4 shows another embodiment of the present invention. In the embodiment shown in FIG. 4, a plurality of portal-shaped legs 11 ′ are mounted on a long frame 1 to place a steel material X or the like.
A traveling wheel 13 'and a driving means 30' are attached to a carrier 10 'formed on 2', and the carrier 10 'is made into a self-propelled cart. The wheels 13 'are placed on a rail 21' which is a transport path 20 ', and some of the wheels 13' are driven by a driving means 30 'such as a motor, so that the transport table 1
Drive 0 'yourself. In addition, the code | symbol 3 in a figure
Reference numerals 1 'and 32' denote power supply means for the motor and the like moving together with the carrier 10 '.

Even when the transfer table 10 'as shown in FIG. 4 is used, the steel material X can be transferred smoothly and without being damaged by the same transfer system as that described above.
However, when the transport path 20 'is not a closed loop continuous path and has a turning point as shown in FIG. 1A and the transport table 10' is transferred on the rail 21 ', the driving means is used. It is necessary to reverse the traveling direction of the transfer table 10 'by 30' before and after the transfer. In the system shown in FIGS. 1 to 3, the driving table 10 is not provided with a driving unit,
Since the driving means 30 was provided in the tracks 20a and 20b to which it was transferred, the transport directions in the respective driving means 30 were not changed even though they were reversed.
If the drive means 30 'is mounted on the carrier 10' as shown in FIG. 4, the drive means 30 'is required to have a function of reversing the drive direction.

Each of the transfer systems introduced above has the following features:
The steel material X to be transferred is not limited to the H-beam. FIG. 5 shows a case in which a channel steel is placed as the steel material X and transported on the transport table 10 or the transport table 10 ′ described above.
If the channel steels are stacked in the state shown in the figure and bound by wires (not shown), the transportation to the stocking site can be performed smoothly. Needless to say, steel materials other than H-section steel and channel steel (such as other types of steel and rods) can be transported similarly.

When a cushioning material such as rubber or FRP is disposed at a contact portion between the transfer table and the transfer path, noise due to the movement of the transfer table is further reduced. For example, in the embodiment of FIG. 1, the lower surface of the rail 13 of the transfer table 10 or the roller 2
It is preferable to attach a cushioning material to the outer peripheral surfaces of the wheels 1 and 22 and, in the case of FIG. 4, to attach the cushioning material to the outer peripheral surface of the wheel 13 'or the upper surface of the rail 21'. The noise reduction effect can also be obtained by forming the rail 13 or the like with a metal having a vibration damping property such as a vibration-proof alloy.

[0036]

According to the present invention , the steel material is conveyed while being mounted on the carrier, so that the surface of the steel material is not damaged during the conveyance. Further, since the binding wire or the like does not get over something, no noise is generated due to the wire or the like, and the wire or the like is not loosened.

The transport table that needs to be returned to the original supply position is
Since the sheet is re-circulated from the supply position to the supply position via the binding position and the payout position, this transfer device allows a plurality of transfer tables to be loaded on a single transfer path and to be moved at the same time, which is efficient and smooth. Transport can be performed.

[0038]

In this transfer device, the transfer table is transferred between two orbits which are brought close to each other in parallel. Therefore, in addition to the above, the transfer path can be passed only to the required place without forming a large loop, and There is also an effect that it is possible to freely set a position, a payout position, and the like, thereby enabling efficient use of the site.

In particular , when the carrier comes on the support, the carrier is moved up and down between the two tracks by raising the support together with the frame and the carrier and moving the support horizontally. There is an advantage that the movement and the horizontal movement can be reliably performed, and each movement distance can be set freely.

In the apparatus according to the second aspect of the present invention, since the cushioning material is disposed at an appropriate position, the noise caused by the movement of the carrier is further reduced.
