DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material distribution device for positioning a long steel material in a storage space at a predetermined position in a predetermined posture.
In particular, although not intended to be limited to this, the present invention relates to a material distribution device for vertically positioning and positioning a steel material long or transformer on a steel material panel and welding the lower end thereof to the upper surface of the panel.

[0002]

2. Description of the Related Art For example, a steel structure in which a plurality of longitudinals are vertically erected on an upper plane of a lower panel and welded to a ship bottom, a deck, a bridge, and the like, and an upper panel is placed on the longitudinals and welded therebetween. Used. In assembling this steel structure, for example, 20
A 20m or 30m long (strip) is vertically set and positioned on an mx 30m panel (large plate), and tack welded by horizontal fillet welding at each point in the longitudinal direction of the long, and the required number of longs After the temporary attachment, the full length of the longe is welded to the panel by performing the main welding.

[0003] The accuracy of assembling such a steel structure is greatly affected by the accuracy of the initial positioning of the longe on the panel. Therefore, the tack welding apparatus disclosed in Japanese Patent Application Laid-Open No. 2-34370 attaches a beam extending in the horizontal x direction perpendicular to the y direction to a portal-type gantry (y direction traveling platform) traveling in the horizontal y direction. A plurality of n carriages are arranged side by side on this beam, and in each carriage, in addition to a pair of horizontal fillet copying welders, a copying ball for pressing the side surfaces of the longitudinal from both sides and an upper end surface of the longitudinal are pressed. The copying roller is provided. The n longes are temporarily placed vertically on a panel at a predetermined pitch, and each of the n carriages is set at each of the longe positions by adjusting the position in the x direction. Pressing the sides of both sides to squeeze and press to straighten the longitudinal, and lower the upper end of the longitudinal with a roller to press the lower end of the longitudinal against the top of the panel, drive the portal frame in the y direction, The longitudinal is tack-welded to the panel by a pair of horizontal fillet copying welders at a predetermined pitch in the y direction. Carriage y
Due to the directional movement, the longe is straightened and straightened in the y direction and closely adhered to the upper surface of the panel, and the above-described tack welding is performed in this state. The longe interval is x
It is determined by the setting of the direction position, and the tacking welding is realized in which the assembling accuracy is high in both the x direction and the y direction, and the longitudinal is correctly vertical.

[0004] However, the placement (distribution) of the long on the panel must be performed by an operator in advance. The present applicant has disclosed in Japanese Patent Application Laid-Open Nos. Hei 6-344185 and Hei 9-9-1 a strip material positioning device that performs both the material distribution and the tack welding.
No. 71990. In these strip positioning devices, the longitudinal plate is clamped from the left and right by a clamper and the horizontal plate is pressed by a pad to support the longitudinal and transport it to an assembly position on the panel.

[0005]

However, since the strip positioning device cannot be held unless the strip is upright, as in the case where the strip is distributed on the panel, the strip positioning device cannot be held. In the yard storage to go to
It is already necessary to arrange the strips in an upright position.

[0006] However, in the strip storage area, when the strip is lowered from the transport vehicle, it is in a sideways posture as shown in FIG. 15, and in many cases, a plurality of strips are stacked. FIG.
5 (a) to 5 (e) show a variety of overlapping of the strips dropped from the transport vehicle. In order to hold it with the strip positioning device, the strip having the L or T shape in cross section is separated one by one, and the long side of the L or T shape is set up vertically and held vertically by the auxiliary tool. There is a need. This is a cumbersome task using a crane.

An object of the present invention is to omit such preparatory work. That is, it is an object of the present invention to provide a material distribution apparatus that can vertically hold and hold a strip member in a sideways posture as shown in FIG.

[0008]

Means for Solving the Problems (1) Main beam (1) extending in the x direction; a plurality of lifting mechanisms (2a, 2b), each supporting the main beam at a distance in the x direction; X drive mechanism (3a, 3b) for driving the mechanism in the x direction; y drive mechanism (4a, 4b) for driving the x drive mechanism in the y direction;
An electromagnet (6) having a suction surface parallel to the axis and the x-axis
(7) a plurality of electromagnetic adsorbers (5a to 5h) which are rotatably supported around a center and which are separated from each other in the x direction and supported by a main beam; and one surface is an electromagnetic adsorber A plurality of steel members (10) adsorbed in the above, which hold the steel material by holding a surface orthogonal to the adsorbed surface and extending in the x direction and a surface on the back side thereof and separated from each other in the x direction and supported by the main beam Side clamper
(9a to 9f).

To facilitate understanding, reference numerals or corresponding items of the corresponding elements of the embodiment shown in the drawings and described later are added in parentheses for reference. The same applies to the following.

According to this, for example, FIG.
As shown in (c), the electromagnet 6 is attracted to the short side of the L-shaped longe 10 by energizing the electromagnet 6 with the attraction surface of the electromagnet 6 facing the short side of the L-shaped longe 10 lying down. By pulling up the 8, the L-shaped longitudinal 10 is suspended. In this process, the electromagnet 6 rotates about the x-axis 7, and the L-shaped longitudinal 10 is hung in a stable posture. FIGS. 13D to 13F show the case of a T-shaped longe.

By holding the long side of the L-shaped or T-shaped longe 10 with the side clampers (9a to 9f) while the longe 10 is suspended as described above, the longe does not swing or wobble and is stable. Can be transported. In other words, the main beam is driven upward and then y-driven to be above the position of the longitudinals on the panel, or the main beam is driven x to position the longitudinal 10 in x and y positions and the main beam is driven downward. By doing so, the longitudinal 10 can be positioned at a predetermined position on the panel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (2) Each electromagnetic adsorber (5a-5h)
An electric motor (13) for rotating and driving the electromagnet (6) and a power transmission mechanism (14) including an electromagnetic clutch (15) are provided.

According to this, the electric motor 13 is driven forward and backward to make the attracting surface of the electromagnet 6 substantially parallel to the short side of the longge 10, and then the electromagnet 6 is driven downward or y-driven to shorten the longe. By energizing after approaching the side, the electromagnet 6
Strongly aspirates Longi. When the electromagnetic clutch 15 is disconnected after energization, the electromagnet 6 can freely rotate.
The attraction of the electromagnet 6 is determined so that the attraction surface of the electromagnet 6 is in close contact with the short side of the longe.

(3) The electromagnetic adsorbers (5a to 5h) start timing when the adsorption energizing switch of the excitation electric circuit for energizing the electromagnet is switched from off to on, and after a predetermined time (2 seconds) elapses. Includes a timer switch that switches off the electromagnetic clutch.

According to this, even if the operator does not operate the electromagnetic clutch, the electromagnetic clutch is automatically disconnected after the electromagnet 6 starts to be energized, and after the electromagnet 6 generates the attraction force, the electromagnetic clutch is surely released. It becomes freely rotatable.

(4) A chain hoist (23) suspended from the main beam and suspending and supporting the frame (8); and a chain hoist located in a symmetrical position between the hoists in the x direction, and attached to the frame (8). , A pair of balancers (24) for applying a force to maintain the rotation axis (7) of the electromagnet (6) parallel to the x-axis.
a, 24b); The chain hoist (23) is large,
It is suitable for lifting heavy objects, so it is used for lifting a longie via an electromagnet.
(8) tends to be unstable, such as turning around a vertical axis or tilting around a horizontal axis. The above-mentioned pair of balancers (24a, 24b) prevents such turning and tilting. Thereby, the posture of the frame 8 supporting the electromagnet 6 is stable.

(5) Each of the side clampers (9a to 9f) is a steel material (10) having one surface adsorbed by an electromagnetic adsorber (5a to 5h).
A plurality of support rollers (16a, 16a) vertically arranged to support a surface extending in the x-direction orthogonal to the sucked surface.
b), a support head (17) for rotatably supporting the support roller about the x axis, a support mechanism (18) for reciprocatingly driving the head in the y direction, and a surface on the back side of the surface of the steel material supported by the support roller. Pressing roller (19a, 19a) opposed to the support roller for pressing
b) a push head (20) for rotatably supporting the push roller about the x axis and a push mechanism (21) for reciprocating the head in the y direction.

According to this, since there are a plurality of rollers arranged vertically in one-side support, the support rollers (16a, 16b)
And the pressing roller (19a, 19b) sandwiches the long side of the longe 10, the long side is automatically vertical. That is, the longe 10 stands upright.

(6) A limit which is located above the steel member (10) sandwiched by the side clampers (9a to 9f) and which stops the descent drive by opening the descent drive circuit of the elevating mechanism when the main beam falls and hits the steel member. A switch (22);

According to this, when the longge 10 rides on the panel and cannot move downward therefrom, the side clampers (9a to 9f) move downward and the main beam also descends. Then, when the limit switch (22) hits the upper short side of the longe 10, the lowering of the main beam stops automatically. Excessive descent of the main beam is automatically prevented.

(7) A plurality of y-adjustment drives, each located between each lifting mechanism (2a, 2b) and the main beam (1), for reciprocating the main beam within a small range in the y direction with respect to the lifting mechanism. Mechanism (11a, 11b);

According to this, the position of the longitudinal 10 with respect to the main beam 1 can be adjusted individually in the y direction at the position of each of the lifting mechanisms (2a, 2b). For example, as shown in FIG. 14 (c), one end of the longitudinal 10 is positioned on the panel 100 in the y direction, and then the other end is positioned in the y direction without driving the main beam in the y direction. Longitude 10 with y adjustment mechanism 11b
The y position of the part there can be adjusted.

(8) Each joint mechanism that allows the main beam to rotate about the y-axis between each lifting mechanism (2a, 2b) and the main beam (1).
(12a, 12b) were inserted.

According to this, since each joint mechanism (12a, 12b) enables the main beam 1 to be tilted around the y-axis, for example, as shown in FIG. The y-position can be adjusted by lowering the panel on the panel 100 and floating the other end, that is, by tilting the main beam 1 around the y-axis.

Other objects and features of the present invention will become apparent from the following description of embodiments with reference to the drawings.

Since the spring balancers 24a and 24b have the same structure and the same mechanical characteristics, and their tows are locked to both ends of the frame 8 in the x direction, the frame 8 is always provided in the x direction. Parallel, and the x-axis body 7 is horizontal,
The equilibrium force is acting so that Electromagnetic adsorber 5
Since a is heavy, the electromagnetic attraction device 5a can be driven up and down by raising and lowering the hoist 23. The structures and functions of the other electromagnetic adsorbers 5b to 5h are the same as those of the electromagnetic adsorber 5a.

FIG. 5 shows the side clamper 9a shown in FIG. The upper ends of the two legs 36a and 36b are fixed to the main beam 1, and have guide rails 37a and 37b. The U-shaped frame 38 is guided by these guide rails 37a and 37b so as to be movable in the vertical direction. Have been. Behind the frame 38, the two legs 36a, 36b extend in the y direction.
And a two-stage positioning hydraulic cylinder 39 is fixed to the cross beam 43, and the tip of the piston rod is connected to the frame 38.

On the left leg of the U-shaped frame 38 in FIG. 5, there is a reference side support roller support mechanism in two upper and lower stages.
The upper one holds two support rollers 16a and 16b, which are arranged vertically and can rotate about the horizontal x-axis, rotatably about the x-axis by the support head 17, and relatively protrudes. The support head 17 is attached to the tip of a piston rod of a weak air cylinder 18.

On the right leg of the U-shaped frame 38 in FIG. 5, there is a push roller support mechanism in two upper and lower stages facing the reference side support roller support mechanism. The upper one holds two push rollers 19a and 19b, which are arranged vertically and rotatable about the horizontal x-axis, rotatably about the x-axis by the push head 20, and the protruding force is relatively small. Push head 2 on the tip of piston rod of strong air cylinder 21
0 is assembled.

As shown in FIG. 5, when distributing a long (short) long side 10 having a short long side (height), the long side 10 is supported by the reference side supporting roller supporting mechanism and the pushing roller supporting mechanism only in the lower stage. The frame 38 is set to the first position (the position in FIG. 5 = the position indicated by the two-dot chain line in FIGS. 7 and 8) by the hydraulic cylinder 39 so as to be sandwiched. However, when distributing a long (long) long 10 having a long side (height), the hydraulic cylinder 39 is held so that the long 10 is sandwiched between the lower and upper reference side support roller support mechanisms and the push roller support mechanism. Thereby, the frame 38 is set at the lowered second position (solid line position on FIGS. 7 and 8).

FIG. 6A shows a horizontal section taken along line 6A-6A in FIG. Air cylinders 18 and 2 are attached to each head of the reference side support roller support mechanism and the push roller support mechanism.
A pair of guide bars (40a, 40b) parallel to 1 are fixed, and these guide bars are guided by a guide sleeve so as to be movable in the horizontal y direction. There are upper and lower reference position stoppers (41a, 42a) behind the support head 17 of the upper and lower reference side support roller support mechanisms.

FIG. 6B is an enlarged view of the upper and lower reference position stoppers. The upper-stage reference position stopper will be described. A stopper plate 41a which is wide in the x and z directions and has a blade-shaped outer shape but has a rectangular wide hole 41ao is movably arranged in the x direction along the stopper guide. The neck of the stopper plate 41a is
2a is connected to the piston rod. At the illustrated position where the piston rod is retracted into the air cylinder 42a, the hole 41ao of the stopper plate 41a is inserted into the guide bar 4a.

0a is outside the outer shape of the stopper plate 41a. The structure and function of the lower reference position stopper are the same as those of the upper reference position stopper.

The head 17 is pushed out by the air cylinder 18 of the upper reference side support roller supporting mechanism, and the rollers 16a and 16b are addressed to the long side surface (front side) of the longe 10, and the longe 10 is turned in the direction opposite to the direction of the arrow y. Push in the direction
After the tail ends (free ends) of the guide bars 40a and 40b have passed the y position of the stopper plate 41a, the stopper plate 41a is pushed out by the air cylinder 42a of the upper reference position stopper in a direction opposite to the direction of the arrow x. The frame around the hole 41ao of the plate 41a is the guide bar 40a, 40b.
Opposes the tail end face of In this state, when the head 20 is pushed out by the air cylinder 21 of the upper push roller support mechanism, the rollers 19a and 19b are applied to the back surface (back surface) of the long side of the longe 10 to push the longe 10 in the direction of the arrow y. Since the air cylinder 21 has a stronger pushing force than the air cylinder 18, the longitudinal 10 is pushed and moved in the direction of the arrow y, that is, the guide bars 40a and 40b are pushed back in the direction of the arrow y, and at this time, the guide bar 40a , 40
The tail end surface of b contacts the frame around the hole 41ao of the stopper plate 41a, and the movement is stopped there. This state is the y-direction reference positioning state of the longitudinal 10 by the supporting roller supporting mechanism and the pushing roller supporting mechanism, and the long sides of the longitudinal 10 are vertical.

As shown in FIG. 7 and FIG.
The cross beam 44, which is stretched over and fixed to the two legs 36a and 36b at the rear of 8, is provided with a limit switch 22 for limiting the downward movement (downward movement) of the main beam 1 in the vertical direction z. The sense rod of the limit switch 22 extends vertically and is driven downward by a compression coil spring. When there is no object that hits the lower end of the sense rod, the lifting mechanism 2a, 2
The operator of the electric switch inserted in the descent drive energizing circuit of b is lowered as shown in FIG. 8 and is switched on. When the main beam 1 descends and the lower end of the sense rod hits the horizontal short side of the longge 10, the sense rod stays at the current height and the electric switch (main beam 1) descends. The electric switch is turned up by the sense rod relative to the electric switch main body, the electric switch is turned off, the descent drive energizing circuit of the lifting mechanism 2a, 2b is opened, and the descent of the main beam 1 is stopped.

2a is shown, and a cross section taken along line 10A-10A is shown in FIG. 10, and FIG. 11 is a right side view. A base 46 is suspended from guide rails 45a and 45b provided on the main beam 1 and extending in the x direction so as to be movable in the x direction. An electric screw mechanism is mounted on the base 46. The screw is reciprocated in the x direction by forward and reverse rotation of the electric motor, and the tip of the screw is connected to the main beam 1. The base 46 reciprocates in the x direction.

The base 46 has left and right lifting mechanisms 48a, 4
8b, and the torch bases 49a and 49b are supported by them so that they can move up and down. Torch base 49
The legs 50a and 50b are movably supported in the y direction by the a and 49b, and are extruded and driven by the x extruding mechanisms 51a and 51b by air cylinders so as to sandwich the longitudinal 10 therebetween in the x direction. The legs 50a and 50b support x and z scanning bases 52a and 52b so as to be able to move up and down and to be rotatable about the z-axis. Each of the scanning bases 52a and 52b has a corner (between the panel 100 and the longitudinal 10). It is equipped with a tracing roller and welding torch to follow the intersection corner). The lower left corner of the longge 10 can be welded with the welding torch of the copying table 52a, and the lower right corner of the longge 10 can be welded with the welding torch of the copying table 52b.

Next, the usage of the above-mentioned material distribution device will be described. First, the yard of the longes 10 is located at the front or the rear in the y direction shown in FIG. 1, and the longes are laid down individually or as shown in FIG. However, their longitudinal axes are parallel or substantially parallel to the x-axis.

The overhead crane CCB is driven in the y direction to move to the Longe storage area. In the longe storage area, in accordance with the length of the long side specified as the distribution target (hereinafter, distribution longe), the length of the long side,
When the length is short, the frame 38 is moved to the first position (the position on FIG. 5 = 2 on FIGS. 7 and 8) by the hydraulic cylinder 39 so that the long is sandwiched between the reference side support roller support mechanism and the push roller support mechanism only at the lower stage. (Dotted chain line position). However, when the long side is long, the frame 3 is moved by the hydraulic cylinder 39 so that the long is held between the lower and upper reference side support roller support mechanisms and the push roller support mechanism.
Reference numeral 8 denotes a second position (solid line position on FIGS. 7 and 8).

Next, the main beam 1 is adjusted substantially parallel to the distribution long. This is possible by individually y-driving the main beam 1 at that position by the y adjusting mechanism 11a or 11b. Next, the electromagnetic adsorbers 5a to 5h are lowered until the electromagnets 6 are in close proximity to the distribution longes, and the electromagnets 6 are moved so that the attraction surfaces of the electromagnets 6 are substantially parallel to the short sides of the distribution longes. Rotate. Then, the electromagnet 6 is energized. When two seconds have elapsed since the start of the energization, the energization of the electromagnetic clutch 15 is automatically cut off, and the electromagnet 6 can rotate about the x-axis body 7.

Next, the electromagnetic adsorbers 5a to 5h are
, And is stopped at a predetermined height. As a result, the material distribution longe 10 is suspended as shown in FIG. 12 (c) or (f), lifted up as shown in FIG. 13 (a), and raised at the height shown in FIG. 13 (b). Stop. In the case of a material distribution longe having a short long side, it is lifted as shown in FIG. 13C, and in the case of a material distribution longe having a long side, as shown in FIG. 13D.

Next, the side clamps 9a to 9f are driven to clamp the long side of the material distribution long. As a result, the long side of the material distribution longitudinal becomes vertical, and furthermore, it becomes a reference position in the y direction with respect to the main beam 1. This state is shown in FIGS. 14A and 14B.

Next, the overhead crane CCB is
Drive y upward, lower main beam 1, and
The ceiling crane CCB is driven y to the 00 upper marking position. Then, the main beam 1 is set to x, y, and so that the lowermost end of the material distribution longage 10 is parallel to the position directly above the marking position.
Drive z adjustment. At this time, the lower end of the material distribution longe 10 is kept at a height slightly away from the upper surface of the panel 100.

Next, as shown in FIG. 14 (c), only one side of the main beam 1 is lowered by one of the elevating mechanisms 2a, 2b, for example, 2a, and stopped when the lower end of the longitudinal touches the panel 100. After correctly aligning to the marking position, it is manually tack welded.

Next, the main beam 1 is again fine-adjusted to accurately align it with the marking position of the material distribution longe 10, and thereafter the main beam 1 is moved only by the lifting mechanism 2b on the opposite side.
Descend. As a result, the entire length of the material distribution panel 1
It means that it landed on 00. Here, the energization of the electromagnet 6 is cut off. Then, a twin fillet welding device at a location where there is no gap between the material distribution longage 10 and the panel 100 is selected, and each device is temporarily welded over a predetermined x length.

Next, the welding device is returned to the retracted position, the clamping by the side clampers 9a to 9f is released, the side clamper is driven upward to the retracted position, and the main beam 1 is driven upward. With the above, the material distribution work of one longe is completed.
