Description

Description: TECHNICAL FIELD The present invention relates to a diaphragm setting device for setting diaphragms at temporary attachment positions in both ends of a square tubular pillar base material. It can be used to manufacture the columns that make up the framework of a residential unit.

[Background technology]

The skeleton of the housing unit that constitutes the unit housing is constructed by welding beams to both ends of a square tubular pillar. When welding a beam to both ends of a column, a diaphragm is welded in both ends of the column in order to increase the strength of the column end where the beam is welded.

Normally, when welding the diaphragm inside both ends of the pillar,
Preliminarily drill holes for temporary attachment of diaphragms at the temporary attachment positions on both ends of the column, set the diaphragms at the temporary attachment positions within the ends of the column, and in this state, temporarily attach and weld multiple diaphragms. After that, the work procedure of welding the entire circumference of the diaphragm with a welding robot is adopted.

By the way, when the diaphragm is set at the temporary attachment positions in both ends of the column, the diaphragm and the diaphragm cannot be accurately set in the temporary attachment positions in both ends of the column unless the columns and the diaphragms are positioned in a predetermined posture with respect to each other. .

Therefore, in the past, a column that has been loaded in the longitudinal direction in a horizontal posture (the posture in which one outer surface of the square tube is horizontal) is
First, the first stopper is applied to perform positioning in the longitudinal direction, and then the pusher presses in a direction orthogonal to the axis of the column to contact the second stopper for positioning in the width direction. The diaphragm is inserted from both ends of the column by a set dimension, and is set at a temporary attachment position in both ends of the column, that is, a diaphragm temporary attachment hole position.

[Problems to be Solved by the Invention]

However, in the conventional diaphragm setting method, since the pillar is positioned in a horizontal posture, when the pillar is positioned in the width direction, the pillar is pressed in the direction orthogonal to the axis of the pillar to abut against the stopper. I need a pusher.

In addition, since the diaphragm is inserted from both ends of the column by the set size, it is possible to set the diaphragm accurately in the temporary attachment position in both ends of the column due to the length dimension error of the column and the positioning error in the longitudinal direction of the column. It was difficult.

Here, an object of the present invention is to solve the above-mentioned conventional drawbacks, a simple structure, and a diaphragm setting device capable of accurately setting the diaphragm at a temporary attachment position in both ends of the pillar base material. To provide.

[Means for solving the problem]

Therefore, the diaphragm setting device of the present invention is a diaphragm setting device that sets the diaphragms at the temporary attachment positions in both ends of the loaded square tubular pillar base material. L adapted to the side surface and supporting the outer side surface thereof in a posture inclined to the horizontal plane
A support mechanism having a character-shaped support surface and supporting the longitudinal direction of the loaded column base material in a substantially horizontal posture, and a column base material on each end of the column base material supported by the support mechanism. Movable bases that are provided so as to be movable in the axial direction and that have a contact surface that comes into contact with the end surfaces of the column base material, and the movable bases that are provided so as to be movable back and forth in the axial direction of the column base material on the movable bases, And an adsorbing means for adsorbing and holding a diaphragm, which is provided at the inner end of each advancing and retracting rod and is capable of inserting the diaphragm into the end portion of the column base material, by suction. To do.

[Work]

The column base material that has been carried in is automatically positioned by the L-shaped support surface of the support mechanism such that the two adjacent outer surfaces are inclined with respect to the horizontal plane and the longitudinal direction is substantially horizontal. .

Here, after the diaphragm is sucked and held by each suction means in such a posture that the diaphragm can be inserted into the end portion of the pillar base material, each movable table is moved in the axial direction of the pillar base material so that the contact surface is the end surface of the pillar base material. Abut.

After that, when each of the advancing and retracting rods is advanced, the diaphragm held by the suction means is inserted into the end portion of the column base material. At this time, since the advancing / retreating rod has a fixed amount of advancing from the contact surface, the diaphragm can be accurately set at the temporary attachment position in both ends of the column base material.

Therefore, in this state, the diaphragm can be temporarily welded to the pillar base material.

Next, the operation in the temporary diaphragm attaching step 46 will be described.

The pillar base material 31 that has been conveyed in the longitudinal direction in the horizontal posture by the first conveyer conveyor 42 is first pushed out by the pusher 61 in the perpendicular direction. Then, the pillar base material 31,
Two inclined rails 62A, 62B and inclined roller conveyor 63
It slides down A and 63B, and is supported by the support member 73 of the support mechanisms 71A and 71B.

At this time, in the pillar base material 31, two adjacent outer surfaces are supporting members.
The L-shaped support surfaces 73A and 73B of the 73 are automatically positioned in a posture inclined with respect to the horizontal plane and in a posture in which the longitudinal direction is substantially horizontal.

Therefore, the suction member 8 of each diaphragm set mechanism 81, 91
After the diaphragm 34 is suction-held on the 9,99 in a predetermined posture, the cylinder 86 of one diaphragm setting mechanism 81 is driven. Then, the movable base 84 is connected to the pillar base material via the link 85.
Since a certain amount is advanced toward the end face of 31, the contact member 84
With the contact surface of B in contact with the end surface of the pillar base material 31, the pillar base material 31
Is extruded by a predetermined amount in the axial direction.

Thereby, after the pillar base material 31 is positioned in the longitudinal direction, the clamp member 75 is rotated about the pin 74 as a fulcrum to clamp the pillar base material 31 from above.

Eventually, when the gripping wheels 88, 98 are advanced to a position where they cannot be pushed in, the diaphragm 34 is set to the temporary attachment position in both ends of the pillar base material 31.

In this state, the diaphragm 34 is temporarily welded to the outer peripheral surface of the pillar base material 31 at three positions, that is, from the three diaphragm temporary holes 32. At this time, as shown in FIG. 12, since the three diaphragm temporary mounting holes 32 of the column base material 31 face the operator, the worker can easily perform the temporary welding while staying in the fixed position, and the welding head Can be left facing down.

Therefore, according to the present embodiment, the carried-in pillar base material 31 is
Since the support mechanisms 71A and 71B automatically position the adjacent two outer side surfaces in a posture inclined with respect to the horizontal plane and in a posture in which the longitudinal direction is substantially horizontal, the mechanism for positioning the pillar base material 31 Can be done easily. In other words, there is an advantage that push or the like as in the past is not required.

Further, on both end sides of the column base material 31 supported by the support mechanisms 71A, 71B, movable bases 84, 9 movable in the axial direction of the column base material 31.

By advancing, the advancing / retreating rods 87, 97 are regulated so that the advancing amount from the contact surface is constant, that is, the inserting amount of the diaphragm 34 is regulated based on the end face of the pillar base material 31. Therefore, the diaphragm 34 can be accurately set at the temporary attachment position in the end portion of the pillar base material 31.

Further, when temporarily attaching and welding the diaphragm 34 set at the temporary attachment position in the end portion of the pillar base material 31, the three temporary diaphragm attachment holes 32 formed at the diaphragm temporary attachment position of the pillar base material 31 face the worker. As the worker is in a fixed position, 3
The three tack positions can be tack welded easily. Moreover, since the welding to these three temporary diaphragm holes 32 can be performed with all the welding heads facing downward, the quality can be stabilized.

The present invention is not limited to the above-described embodiments, and includes the following modifications.

For example, the tilt angles of the support surfaces 73A and 73B that support the two adjacent outer surfaces of the pillar base material 31 are not limited to the angles described in the above embodiment. The point is that the two outer surfaces adjacent to each other of the pillar base material 31, which have slid down the inclined roller conveyors 63A and 63B, are automatically positioned so as to be inclined with respect to the horizontal plane.

In the above embodiment, only the movable base 84 of the one diaphragm setting mechanism 81 is automatically moved by the cylinder 86, but the other diaphragm setting mechanism 91 is used.
The movable table 94 may also be automatically moved by a driving means such as a cylinder. Furthermore, advance / retreat rod 8
The 7,97 may also be moved back and forth by driving means.

Further, in the above-mentioned embodiment, the suction means for suction-holding the diaphragm 34 is constituted by the suction members 89, 99 made of permanent magnets, but the diaphragm 34 may be suction-held by suction of air.
