Description

[Detailed description of the invention] This invention can be used to suspend large workpieces vertically in a predetermined position, such as the cab side frame of a van-type automobile, in a space where the space in the height direction is small. The present invention relates to a hanging conveyance device for hanging transportation, and in particular, to provide a hanging conveying device configured so that hanging transportation can be easily carried out even when the open space from the top surface of a finishing table to the ceiling is limited and small. The purpose is to

Embodiments of this invention will be described below with reference to the drawings.

FIG. 1 shows a side view of a hanging conveyance line to which a hanging conveying device according to the invention is applied. It is bridged on the ceiling rail 3 of the frame 2 so as to be able to reciprocate freely, and is supported on the upper side of the finishing table 4 by a support plate 6 which is set to be swingable in the directions of arrows c and d by the operation of a cylinder 5. The window 7a of a workpiece 7, such as the cabin side frame of a van-type automobile, is hung at position A, and the workpiece is conveyed through position B to position C, and delivered to the receiving arm 8a of the receiving mechanism 8 at position C. It's becoming like that.

The hanging transport device 1 is clearly shown in FIGS. 2 and 3.

In the figure, 9 indicates a conveyance table, and this conveyance table 9 is driven by a traveling drive mechanism (not shown),
It is movable back and forth in the directions of arrows a and b, and has a pair of arm portions 9a and 9b protruding from both left and right sides of the tip.

Reference numeral 10 denotes a cylinder, which is mounted and fixed on the conveyance table 9, and is provided with a piston rod 12 having a pair of left and right rollers 11a, 11b rotatably attached to its tip.

13a and 13b indicate a pair of left and right arms. These arms 13a, 13b are swingably supported by shafts 14 provided in the left-right direction at the distal end arm portions 9a, 9b of the conveyance table 9.
Further, arc-shaped cam grooves 15 into which the rollers 11a and 11b are fitted are formed respectively. The distance of the cam groove 15 from the shaft 14 gradually increases as the piston rod 12 moves toward the backward direction (direction f in FIG. 2).

Therefore, as the piston rod 12 of the cylinder 10 moves forward and backward in the directions of arrows e and f,
Arms 13a and 13b are arranged in the direction of arrow g with shaft 14 as a fulcrum.
It swings in the h direction, that is, in the vertical direction.

16a and 16b indicate a pair of left and right hanging arms. These hanging arms 16a, 16b are for hanging the upper edge of the window portion 7a of the workpiece 7 by the operation described later, and the intermediate portion 16
a ₁ and 16b ₁ are supported on the tips of the arms 13a and 13b by left and right shafts 17 or pins so as to be able to swing in the directions of arrows i and j, and a hanging support seat is provided on the upper surface of the tips. 18, and an elongated hole 19 is formed through the rear end.

20a and 20b are a pair of rods, which are movable in the axial direction guided by guides 21 provided on the arms 13a and 13b, and one end of which is inserted into the long hole 19 of the hanging arms 16a and 16b. A spring 23 is pivotally connected to the guide 21 and the rods 20a, 20b through a pin 22, and which always applies a spring force in the direction of lifting the rear ends of the hanging arms 16a, 16b (in the direction of arrow i). It is inserted between the flange 24 formed at the end.

25a and 25b indicate a pair of left and right bars. The rear ends of these bars 25a, 25b are pivotally supported by the arm portions 9a, 9b of the conveyance table 9 by means of left and right shafts 26 or pins, and the lower surfaces of the tips are attached to the other ends of the rods 20a, 20b. It is adapted to come into contact with the roller 27.

The inner surfaces of the bars 25a, 25b are provided with inclined surfaces 28 that slope upward toward the tips, and these inclined surfaces 28 correspond to the line of motion of the rollers 11a, 11b attached to the piston rod 12.

In the above configuration, when the workpiece 7 is lying down in the state shown by the imaginary line at position A in FIG. It is located at the _A1 position (the position indicated by the imaginary line in FIG. 1) corresponding to the A position, and each component is in the state shown in FIGS. 2 and 3.

When hanging the workpiece 7, first hang the finishing table 4.
Operate the upper cylinder 5 to remove the support plate 6 and workpiece 7.
is raised to the state shown by the solid line, and then the cylinder 10 of the suspended conveyance device 1 is operated to move the piston rod 12.
advance in the direction of arrow e.

As the piston rod 12 moves forward, the left and right pair of rollers 11a, 11b move toward the arms 13a, 13b.
The arms 13a and 13b move forward while pressing the lower edge of the cam groove 15, and the arms 13a and 13b swing in the direction of the arrow g about the shaft 14, resulting in the state shown in FIG.

As the piston rod 12 moves forward to the stroke end position, the rollers 11a, 11b
The bars 25a, 25b roll on an upwardly sloped slope 28 toward the tips provided on the inner surfaces of the bars 25a, 25b, pushing the bars 25a, 25b downward using the shaft 26 as a fulcrum, and further rolling the bars 25a, 25b. The state shown in FIG. 5 is obtained by rolling contact with the upper end surface of. bar 25 at the same time
The lower end surfaces of the rods 20a and 20b push down the rollers 27 at the tips of the springs
The rods 20a, 20b are pushed down using the guide 21 against the spring force of 3, and the hanging arms 16a,
16b is swung in the direction of arrow j using the shaft 17 as a fulcrum,
The upper edge of the window 7a of the workpiece 7 is hung and supported by the hanging support seat 18.

After obtaining the above hanging support state, the hanging support device 1 is moved in the direction of arrow a using the ceiling rail 3 of the frame 2 as a guide, and is stopped at position C after passing through position B.

A receiving mechanism 8 is waiting at position C, and its receiving arm 8a is inserted into the window 7a of the workpiece 7. Therefore, by operating the cylinder 10 and retracting the piston rod 12 in the direction of arrow f, the hanging arms 16a, 16b are brought into the state shown in FIG. 4, and the workpiece 7 can be transferred to the receiving arm 8a. can.

Thereafter, the piston rod 12 is further retreated, the arms 13a, 13b, the rods 20a, 20b, and the bars 25a, 25b are returned to the states shown in FIG. 2, and the hanging conveyance device 1 is returned in the direction of arrow b. A ₁ position is reached, and then the same operation as above is repeated to hang and transport the next workpiece 7.

In the above embodiment, the rollers 11a, 11
b, arms 13a, 13b, hanging arm 16
a, 16b, rods 20a, 20b, and bars 25a, 25b are used in pairs on the left and right, respectively. Even if configured, the same effects as in the above embodiment can be obtained.

As explained above, this invention has a simple structure because it operates one cylinder to reverse the arm, and the bar and rod follow and operate to enable the hanging arm to be hung and transferred. Moreover, there is an advantage that the workpiece can be hung and transported in a space where the space in the height direction is small.
