Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a longi distribution material mounting apparatus that positions and welds a steel material longge at a predetermined position on a steel plate material.

  As this type of Longi distribution material attaching device, there is one proposed in Patent Document 1, for example.

JP 2013-1111585 A

  In the Longi distribution material mounting apparatus according to Patent Document 1, when the pressurizing unit 100 positions and welds the Longi 102 in a predetermined posture at a predetermined position on the plate member 101 as shown in FIG. The longi 102 is pressed against the plate material 101 using the longi pressing tool 103 that can be pressed against the upper surface of the longi 102, while the long plate 102 is disposed on both the left and right sides of the longi pressing tool 103 so as to straddle the longi 102 left and right. The pair of plate material adsorbing tools 104a and 104b are used to apply a reaction force against the pressing force applied from the longi pressing tool 103 to the longi 102 to the plate material 101. Here, the pair of plate material adsorbing tools 104a and 104b is suspended from a lifting body 106 that is lifted and lowered by the expansion and contraction operation of the pair of air cylinders 105a and 105b, and the pair of plate materials is extended by the extension of the pair of air cylinders 105a and 105b. The suction tools 104a and 104b are lowered, and the pair of plate material suction tools 104a and 104b are raised by contraction of the pair of air cylinders 105a and 105b.

  According to the longi distribution material mounting apparatus including the pressure unit 100, the longi 102 is pressed against the plate member 101 by the longi pressing tool 103, and the pressing force applied to the longi 102 by the longi pressing tool 103 is countered. Since the reaction force is applied to the plate material 101 by the pair of plate material adsorbing tools 104 a and 104 b, it is possible to reliably prevent a gap from being generated between the plate material 101 and the longe 102, and welding the longe 102 to the plate material 101. Can be performed appropriately.

  By the way, in the board | plate material 101 and the longi 102 positioned on the board | plate material 101, the board | plate material 101 may incline up and down with respect to a horizontal surface on the left-right side of the longge 102. FIG. The pair of plate material adsorbing tools 104a and 104b are lowered by the extension of the pair of air cylinders 105a and 105b with respect to the plate material 101 having such an inclination, and the plate material 101 is adsorbed using the plate material adsorbing tools 104a and 104b. When trying to do so, as shown in FIG. 10B, one of the plate material adsorbing tools 104a and 104b comes into contact with the plate material 101 first, and at this point, a pair of more Since the plate material adsorbing tools 104a and 104b cannot be lowered, the other plate material adsorbing device 104b cannot contact the plate material 101, and the plate material 101 cannot be adsorbed by both the pair of plate material adsorbing tools 104a and 104b. It will be.

  For this reason, in the conventional longi distribution material mounting apparatus, when the plate material 101 is tilted up and down on the left and right sides of the longe 102, a necessary reaction force cannot be applied to the plate material 101. There is a problem in that it is impossible to reliably prevent a gap from being generated in the sheet material and welding of the longe 102 to the plate material 101 cannot be performed appropriately.

  The present invention has been made in view of the above-described problems, and even if the plate material is inclined up and down on the left and right sides of the longe, the longi arrangement that can reliably adsorb the plate material with a pair of plate material adsorbing tools. The object is to provide a material mounting device.

In order to achieve the above object, a longi distribution material mounting device according to the present invention includes:
When positioning and welding a longe at a predetermined position on a plate material, the longi is pressed against the plate using a longi pressing tool that can be pressed against the upper surface of the longe, while Longe that applies a reaction force against the pressing force applied to the longi from the longi pressing tool using a pair of plate material adsorbing tools that are arranged and adsorb the plate material so as to straddle the left and right sides of the longe. In the distribution material mounting device,
A tilting mechanism for tilting the pair of plate material adsorbing tools to the left and right sides of the longe so as to follow the vertical tilt of the plate material on the left and right sides of the longe is provided (first invention).

  In the present invention, each plate material adsorbing tool is configured such that a magnet body is slidably mounted in the left-right direction of the longitudinal on the pull-up bar on the lower end side of the pull-up bar extending in the vertical direction. Is preferred (second invention).

  According to the longi distribution material mounting device of the present invention, the pair of plate material adsorbing tools are tilted to the left and right sides of the longi by the tilting mechanism so as to follow the vertical tilt of the plate material on the left and right sides of the longi. Even if the plate material is tilted up and down, the plate material can be reliably adsorbed by the pair of plate material adsorbing tools.

  According to the second invention, since the magnet body can slide in the left and right direction of the long rod with respect to the pull-up rod, the operation of causing the pair of plate material adsorbing tools to tilt to the left and right sides of the long and contacting the plate material is further performed. It can be done smoothly.

On both sides of the carrier 42 in the Y-axis direction, a pair of air cylinders 44a and 44b extending in the vertical direction are disposed. In each air cylinder 44a, 44b, a pair of support shafts 45, 45 (only the front side is shown in FIG. 3) are provided at the middle portion in the vertical direction of the air cylinder body so as to protrude on both sides in the X-axis direction. A bracket 46 is attached to the tip of the cylinder rod.
The air cylinders 44a and 44b and the carrier 42 are joined via hinges 47a and 47b. The hinges 47 a and 47 b are configured by a pair of support shafts 45 and 45 provided on the air cylinder body being rotatably supported by a bracket 48 provided on the carrier 42.

  The elevating body 43 is elevated and guided by a linear guide mechanism 50 provided between the elevating body 43 and the carrier 42, and is supported by being suspended from the carrier 42 via a pair of air cylinders 44a and 44b.

  The linear guide mechanism 50 includes a pair of linear shafts 51 and 51 (shown only on the front side in FIG. 3) that are disposed on both sides of the carrier 42 in the X-axis direction and extend in the vertical direction. , 51 are connected to the lifting body 43, and the pair of linear shafts 51, 51 are mounted on the carrier 42 via a pair of linear bushes 52, 52 (only the front side is shown in FIG. 3). .

  Each air cylinder 44a, 44b and the elevating body 43 are joined via hinges 55a, 55b. The hinges 55a and 55b are configured by connecting a bracket 46 attached to the tip of the cylinder rod to a bracket 56 provided on the elevating body 43 via a pin 57.

<Description of plate material adsorbing tool>
A pair of plate material adsorbing tools 58 a and 58 b are suspended from the lower surface side of the elevating body 43. These plate material adsorbing tools 58a and 58b are juxtaposed in the Y-axis direction with a sufficient distance to receive the longi 4 placed along the X direction on the plate material 3 so as to be sandwiched therebetween.

  Each plate material adsorbing tool 58a, 58b is composed of a pulling bar 59 extending in the vertical direction and a powerful electromagnet having a rectangular parallelepiped shape long in the X-axis direction (see FIG. 4). The magnet body 60 is provided. Note that, for example, a suction cup body may be used instead of the magnet body 60 and the plate material 3 may be attracted by a vacuum force.

As shown in FIG. 5 (a), a bracket 61 projects from the lower end side of the pull-up bar 59, and a pair of brackets 62a, 62 b is erected on the upper surface side of the magnet body 60.
The bracket 61 on the pulling bar 59 side and the pair of brackets 62 a and 62 b on the magnet body 60 side are connected by a pin 63.
Between the bracket 61 and the pin 63, a spherical bearing 64 with a slide mechanism having a thrust bush 64a is interposed. The spherical bearing 64 serves not only to support the tilting motion of the pin 63 in any direction but also to support the motion of the pin 63 in the axial direction and the motion of the pin 63 around the axis. The spherical bearing 64 allows the magnet body 60 to tilt in any direction with respect to the pull-up bar 59, and can slide in the Y-axis direction along the axis of the pin 63. It can swing in the X-axis direction with reference to the 63 axis.

A compression coil spring 65a is inserted between one bracket 62a of the pair of brackets 62a and 62b on the magnet body 60 side and the bracket 61 on the pull-up bar 59 side so as to fit outside the pin 63. Yes. Similarly, a compression coil spring 65b is interposed between the other bracket 62b of the pair of brackets 62a and 62b on the magnet body 60 side and the bracket 61 on the pull-up bar 59 side so as to fit outside the pin 63. It is inserted.
Thus, by applying the respective urging forces of the compression coil springs 65a and 65b fitted to both end portions of the pin 63 to the magnet body 60, when no load in the Y-axis direction acts on the magnet body 60, the magnet body. 60 is positioned at a neutral position whose center in the Y-axis direction is directly below the pull-up bar 59.

  According to the plate material adsorbing tools 58a, 58b, the plate material 3 can be adsorbed with a simple configuration, and even if the plate material 3 is slightly bent or deformed or tilted up and down on the front and back sides thereof, The magnet body 60 moves so as to follow the bending, deformation, inclination, etc. of the plate material 3, and the plate material 3 can be reliably adsorbed.

<Description of tilt mechanism>
As shown in FIG. 3, in the reaction force applying device 40, a carrier 42, a lifting body 43, a pair of air cylinders 44 a, 44 b and four hinges 47 a, 47 b, 55 a, 55 b, and a lifting body 43 A tilting mechanism 67 is constructed that tilts the pair of plate material adsorbing tools 58a and 58b to the left and right sides of the longitudinal 4 by a floating join 53 that connects the linear shaft 51 and the lifting body 43 while allowing the tilting of the long shaft 4.

  In this tilting mechanism 67, one link length between the carrier 42 and the lifting / lowering body 43 is changed by the expansion / contraction operation of one air cylinder 44a of the pair of air cylinders 44a and 44b, and the carrier 42 and the lifting / lowering body. The other link length with respect to 43 is made to change by the expansion and contraction operation of the other air cylinder 44b of the pair of air cylinders 44a and 44b.

  For example, as shown in FIG. 8, when the expansion / contraction length of one air cylinder 44a is relatively long with respect to the expansion / contraction length of the other air cylinder 44b, the lifting / lowering body 43 is on one side in the Y-axis direction. The pair of plate members so that one plate member adsorber 58a of the pair of plate member adsorbers 58a, 58b is relatively lower than the other plate member adsorber 58b. The suction tools 58a and 58b are inclined to one side in the Y-axis direction (left side in FIG. 8 of the longitudinal 4).

  On the contrary, as shown in FIG. 9, when the expansion / contraction length of the other air cylinder 44b is relatively long with respect to the expansion / contraction length of the one air cylinder 44a, the lifting / lowering body 43 moves to the Y axis. Inclined to the other side of the direction (right side in FIG. 9 of Longi 4), so that the other plate material adsorber 58b of the pair of plate material adsorbers 58a, 58b is relatively lower than one plate material adsorber 58a. The pair of plate material adsorbing tools 58a, 58b is inclined to the other side in the Y-axis direction (the right side in the same figure of the longitudinal 4).

<Description of Longi pressing device>
As shown in FIG. 7, the longi pressing device 41 is a device that presses the longi 4 against the plate material 3, and as shown in FIG. 4, the longi pressing device that is attached to the lifting body 43 via the speed reducer 68. A tool 69 is provided. This longi pressing tool 69 is a rod-like member that is arranged so as to protrude from the inside of the lifting / lowering body 43 toward the upper surface of the longi 4 through an insertion hole 70 provided in the center of the lower surface of the lifting / lowering body 43. The push rod 71 is provided with a threaded portion provided on the outer periphery thereof, and a contact portion 72 disposed on the lower end side of the push rod 71.

As shown in FIG. 5B, the abutting portion 72 includes a pressing seat 73 and a pressing sheet 74 made of, for example, a rubber sheet material that is attached to the lower surface of the pressing seat 73 and pressed against the upper surface of the longage 4. And is configured.
A bracket 75 projects from the upper surface side of the pressing seat 73, and a pair of brackets 76 a and 76 b are vertically provided on the lower end side of the pressing rod 71 with a predetermined interval in the Y-axis direction so as to sandwich the bracket 75. Has been.
The bracket 75 on the pressing seat 73 side and the pair of brackets 76 a and 76 b on the pressing rod 71 side are connected by a pin 77.
A spherical bearing 78 is interposed between the bracket 75 and the pin 77. With this spherical bearing 78, the abutting portion 72 can tilt with respect to the pressing rod 71 and the pin 77. Can be swung in the X-axis direction with reference to the axis line.

  According to the longi pressing tool 69, even if the center position with respect to the longi 4 is slightly shifted or the longi 4 is slightly inclined on the front, rear, left and right sides, it is possible to reliably apply a pressing force to the longe 4. Can do.

  As shown in FIG. 4, an electric motor 80 is connected to the speed reducer 68 via a coupling 79 so that power can be transmitted. The reduction gear 68 is not shown in detail in the drawing, but a worm gear integrally provided on an input shaft to which rotational power from the electric motor 80 is input, and a screw of the pressing rod 71 that meshes with the worm gear. And a nut member that is screwed into the portion.

  In the longitudinal pressing device 41, the unidirectional rotational power from the electric motor 80 is transmitted to the pressing rod 71 via the speed reducer 68 by the unidirectional rotational operation of the electric motor 80. As a result, the longi pressing tool 69 is lowered toward the upper surface of the longi 4. On the other hand, by the rotational operation in the other direction of the electric motor 80, the rotational power in the other direction from the electric motor 80 is transmitted to the pressing rod 71 via the speed reducer 68. As a result, the longage pressing tool 69 is raised toward the inside of the elevating body 43.

  The positioning, pressurizing, and welding operations of the longi 4 by the longi distribution material mounting device 1 configured as described above will be described below mainly with reference to FIGS. 1 and 2 and FIGS.

<Description of longi positioning operation: see FIG. 1>
First, the crane girder 6 is run in the Y-axis direction by the Y-axis drive mechanisms 5 and 5 to move the longi distribution material mounting device 1 to the longi place not shown, and the short side of the longe 4 placed in the longi place Is attracted by an electromagnetic attracting device 21 (see FIG. 2A), is lifted by hoisting 22 (see FIG. 2A), and the longe 4 is stopped at a predetermined height. (See (b)), the long side 4 is held vertically while sandwiching the long side surface of the long point 4.
Next, the longi 4 is moved to the vicinity of the marking position of the plate 3 by the cooperation of the crane girder 6 and the elevating mechanisms 8 and 8 by the Y-axis drive mechanisms 5 and 5, and the lowermost end of the longe 4 is parallel to the marking position. The position of the main beam 11 is adjusted by the Y-axis adjusting mechanisms 10 and 10 so that At this time, the longest end 4 of the longge 4 is stopped at a height position slightly separated from the upper surface of the plate 3.

  Next, only one side of the main beam 11 is lowered by one of the two lifting mechanisms 8 and 8 so that the lower end of the longe 4 touches the plate 3 and is correctly aligned with the marking position. Then, it is tack welded manually. After the precise alignment of the longe 4 to the marking position is performed again by fine adjustment of the position of the main beam 11, the main beam 11 is lowered only by the other of the two lifting mechanisms 8, 8. Let As a result, the entire longi 4 has landed on the plate 3.

<Description of normal long pressure application: see FIGS. 6 and 7>
Next, as shown in FIG. 6, the pair of air cylinders 44 a and 44 b are extended to lower the elevating body 43, and the magnet bodies 60 and 60 of the pair of plate material adsorbing tools 58 a and 58 b come into contact with the plate material 3. At this point, the lowering operation of the elevating body 43 is stopped.
Next, the electric motor 80 (see FIG. 4) is rotated in one direction to lower the longage pressing tool 69 toward the upper surface of the longage 4, and as shown in FIG. When the portion 72 comes into contact with the upper surface of the longe 4, the lowering operation of the longi pressing tool 69 is temporarily stopped.

Next, the electric motor 80 (see FIG. 4) is operated to rotate in a predetermined direction to push down the longage pressing tool 69 that is in contact with the upper surface of the longi 4. Thus, as the pressing force is applied to the longe 4, a reaction force that opposes the pressing force is applied to the plate member 3 via the pair of plate member adsorbers 58a and 58b. The air cylinders 44a and 44b are for raising and lowering the elevating body 43, and are in a free state that can be expanded and contracted during the pushing and pulling operation. In other words, the air cylinders 44a and 44b act as cushions so that an extra load is not applied to the main beam 11, the elevating mechanism 8, the joint mechanism 9, the Y-axis adjusting mechanism 10, and the like.
In this way, the longitudinal 4 is pressed against the plate 3 by the longi pressing device 41, and a reaction force against the pressing force is applied to the plate 3 by the reaction force applying device 40, thereby creating a gap between the plate 3 and the longe 4. Without causing the entire longage 4 to adhere to the plate 3.

<Description of Longe Welding Operation: See FIG. 2 (c)>
And after interrupting | blocking the electricity supply to the electromagnetic adsorption device 21 (refer Fig.2 (a)), fillet welding with the board | plate material 3 and Longi 4 is performed by the three welding units 14,14,14, and each welding unit is carried out. Tack welding is carried out over a predetermined length per 14.

  By the way, in the board | plate material 3 and the longi 4 positioned on the board | plate material 3, the board | plate material 3 may incline up and down with respect to a horizontal surface at the left-right side of the longi 4. FIG. Thus, the longi pressurization operation in the case where the plate member 3 has a vertical inclination will be described below.

<Explanation of the Longe pressurizing operation when the plate material is inclined: See FIGS. 8 and 9>
As shown in FIG. 8, the plate 3 is tilted up and down so that one side (left side in FIG. 8) of the plate 3 is relatively lower than the other side (right side in FIG. 8) on the left and right sides of the longe 4. The longi pressurization operation in the case of being is as follows.

  When the pair of air cylinders 44 a and 44 b are extended to lower the elevating body 43, the other plate material adsorbing tool 58 b of the pair of plate material adsorbing tools 58 a and 58 b first contacts the plate material 3. Then, the extension operation of the other air cylinder 44b of the pair of air cylinders 44a, 44b stops, and only the extension operation of one air cylinder 44a continues until one plate material adsorbing tool 58a contacts the plate material 3. The expansion / contraction length of one air cylinder 44a is relatively longer than the expansion / contraction length of the other air cylinder 44b, and the tilting mechanism 67 causes the lifting body 43 to move to one side in the Y-axis direction (the figure of the long 4). 8, the pair of plate material adsorbing tools 58 a and 58 b are arranged on one side in the Y-axis direction (on the long 4 side) so that one plate material adsorbing device 58 a is relatively lower than the other plate material adsorbing device 58 b. In this figure, the pair of plate material adsorbing tools 58a and 58b can be brought into contact with the plate material 3 by being inclined to the left side).

  On the other hand, as shown in FIG. 9, the plate 3 is vertically moved so that the other side of the plate 3 (the right side in FIG. 9) is relatively lower than the one side (the left side in FIG. 9). The long pressure application operation when tilted is as follows.

  When the pair of air cylinders 44 a and 44 b are extended to lower the elevating body 43, one plate material adsorbing tool 58 a of the pair of plate material adsorbing tools 58 a and 58 b first contacts the plate material 3. Then, the extension operation of one air cylinder 44a of the pair of air cylinders 44a and 44b stops, and only the extension operation of the other air cylinder 44b continues until the other plate material adsorbing tool 58b contacts the plate material 3. The expansion / contraction length of the other air cylinder 44b becomes relatively longer than the expansion / contraction length of the one air cylinder 44a, and the tilting mechanism 67 causes the lifting / lowering body 43 to move to the other side in the Y-axis direction (the view of the longi 4). 9, the pair of plate material adsorbing tools 58 a, 58 b are placed on the other side in the Y-axis direction (on the long side 4) so that the other plate material adsorbing device 58 b is relatively lower than the one plate material adsorbing device 58 a. In the same figure, it is inclined to the right side), and both of the pair of plate material adsorbing tools 58a and 58b can be brought into contact with the plate material 3.

  In this way, after the plate material 3 is adsorbed by both of the pair of plate material adsorbing tools 58a and 58b, a pressing operation by the longage pressing tool 69 similar to that described above is performed, thereby creating a gap between the plate material 3 and the longi 4. Without this, the entire longage 4 can be brought into close contact with the plate 3.

<Description of effects>
According to the longi distribution material mounting device 1 of the present embodiment, even when the plate 3 is tilted up and down on the left and right sides of the longi 4, the pair of plate material adsorbers 58a and 58b so as to follow the vertical tilt of the plate 3 Is tilted to the left and right sides of the longitudinal 4 by the tilting mechanism 67, so that the plate material 3 can be reliably adsorbed by the pair of plate material adsorbers 58a, 58b. Thereby, it is possible to reliably prevent the gap between the plate 3 and the longe 4 by reliably applying the reaction force against the pressing force to the plate 3 while pressing the Longe 4 against the plate 3. It is possible to appropriately weld the longi 4 to the plate material 3.
Further, since the magnet body 60 is slidable with respect to the pull-up bar 59 in the left-right direction of the longitudinal 4, the sliding position of the magnet body 60 changes according to the inclination as shown in FIGS. The operation of tilting the plate material adsorbers 58a, 58b to the left and right sides of the longi 4 and bringing them into contact with the plate material 3 can be performed more smoothly.

  As mentioned above, although the longi distribution material mounting apparatus of this invention was demonstrated based on one embodiment, this invention is not limited to the structure described in the said embodiment, In the range which does not deviate from the meaning, the structure Can be changed.

  Since the longi distribution material mounting device of the present invention has a characteristic that the plate material can be reliably adsorbed by a pair of plate material adsorbing tools even if the plate material is inclined up and down on the left and right sides of the longi, For example, it can be suitably used for assembling a steel structure on a ship bottom, a deck, a bridge or the like.
