Each of the work carts 14 includes the transport chain 12
Are connected at predetermined intervals, and can be moved on the line as the transport chain 12 moves.

Specifically, as shown in FIG. 2, each work cart 14 has a table 18 and four legs 20, and a reinforcing frame 22 is attached to each leg 20. A caster 24 is attached to the lower end of each leg 20.

Further, as shown in FIGS. 2 and 3, the transport chain 12 includes a roller 26 and an upper and lower link plate 2.
As shown in FIG. 2, an L-shaped mounting bracket 30 is mounted on the upper link plate 28, and the work carriages 14 are attached to the mounting bracket 30. Are fixed.

The work cart 14 is a caster 2
4 allows it to move around the floor surface along the transport chain 12 in a trackless manner on a plane.

In this manner, the work can be efficiently performed with a small installation area without increasing the length of the line.

The work carts 14 are supplied with compressed air as energy of a jig 32 used for assembling aluminum building materials and the like, a filler as a liquid material, and the like. Is provided with a plurality of, for example, two jig / tool connection portions 34.

As the jig 32, for example, an air drill for drilling, an air driver for screw tightening, an air lifter for lifting an aluminum building material or the like, or a filling gun for filling a filler such as styrene foam into the aluminum building material. Etc. are connectable.

As described above, by providing the jig / tool connection portion 34 on each work cart 14, the compressed air can be supplied to the jig 32 only by connecting the jig 32 to the jig connection portion 34. In addition, since the jig 32 is directly pulled out from the work cart 14, the work can be performed efficiently without disturbing the work as compared with the case where the jig 32 is suspended from the ceiling as in the related art. Yes, and
The compressed air can be supplied to the air lifter or the like without using a separate compressed air supply system, and the structure can be simplified.

The compressed air is supplied to an air compressor 36 as an energy supply source and a first air compressor 36 as an energy supply system.
Compressed air supply hose 38 and second compressed air supply hose 40, compressed air distribution hose 42 as an energy distribution system, retraction hose 44, and cushion tank 4
6 and a connection hose 48, and is supplied to one jig / tool connection portion 34 of each work vehicle 14.

The first compressed air supply hose 38 is connected from the air compressor 36 to a support wheel 50 suspended and supported rotatably on the ceiling.

One end of the second compressed air supply hose 40 is rotatably connected to the first compressed air supply hose 38 via a coupler (not shown), and is rotatable on the outer peripheral portion of the support wheel 50 together with the support wheel 50. , And
The other end is rotatably connected to the compressed air distribution hose 42 via a coupler (not shown).

The compressed air distribution hose 42 is formed in an endless shape, and as shown in FIGS.
Are partially locked at predetermined intervals on the running center line of the link plate 28 via a locking tool 52, and the transport chain 12
And can be rotated.

As described above, by allowing the compressed air distribution hose 42 to travel together with the transport chain 12, the relative positional relationship between the work vehicle 14 and the compressed air distribution hose 42 can be kept constant.

Further, since the compressed air distribution hose 42 is locked on the traveling center line of the link plate 28 of the transport chain 12, the moving speed of the compressed air distribution hose 42 and the transport chain 12 can be maintained even when the sprocket 16 passes. Since it is always constant, expansion and contraction of the compressed air distribution hose 42 can be suppressed.

Further, since the compressed air distribution hose 42 is partially locked with respect to the transport chain 12 and is opened at the position where the compressed air is distributed, maintenance is easy.

Then, the compressed air distribution hose 42 is connected to a cushion tank 46 via a draw-in hose 44, temporarily stores compressed air in the cushion tank 46, and stores the compressed air stored in the cushion tank 46 into a connection hose. Each jig 3 via the jig 48 and the jig connection 34
2 can be supplied with compressed air.

As described above, by supplying the compressed air to the jig 32 via the cushion tank 46, it is possible to reliably supply the compressed air from one compressed air distribution hose 42 to the plurality of work carts 14. it can.

Since the second compressed air supply hose 40 and the compressed air distribution hose 42 are movable, it is desirable that the second compressed air supply hose 40 and the compressed air distribution hose 42 be formed of an elastic material or a flexible material.

The filler is supplied from a raw material tank 54 as a liquid material supply source via a supply pump 56 to a first filler supply hose 58 and a second filler supply hose 60 as a liquid material supply system. The material is supplied to a filler distribution hose 62 as a material distribution system, a drawing hose 64, and the other jig / tool connection portion 34.

The first filler supply hose 58 is connected to the support wheel 50 in the same manner as the first compressed air supply hose 38.

One end of the second filler supply hose 60 is rotatably connected to the first filler supply hose 58 via a coupler (not shown), and is rotatable on the outer peripheral portion of the support wheel 50 together with the support wheel 50. And the other end is rotatably connected to a filler distribution hose 62 via a coupler (not shown).

Like the compressed air distribution hose 42, the filler distribution hose 62 is formed in an endless shape, and is disposed on the traveling center line of the link plate 28 of the transport chain 12 together with the compressed air distribution hose 42 and the locking member 52. , And is partially locked at a predetermined interval via the transport chain 12 so as to be rotatable.

The drawing hose 64 is connected directly from the filling material distribution hose 62 to the other jig / tool connection portion 34 so that the filling material pumped by the supply pump 56 can be directly supplied to the jig 32 such as a filling gun. .

The second filler air supply hose 60 and the filler air distribution hose 62 are connected to the second compressed air supply hose 40.
Like the compressed air distribution hose 42, it is made movable, so that it is desirable to be formed of an elastic material or a flexible material.

As described above, in addition to the energy of the compressed air or the like, the work cart 14 is filled from the filler stock solution tank 54 through the first and second filler supply hoses 58 and 60 and the filler distribution hose 62. The material can be simplified and supplied in an unobtrusive configuration, thereby improving work efficiency.

FIG. 5 is a view showing a carriage transport device according to another embodiment of the present invention.

In this embodiment, a rotary table 68 is arranged in the floor space between the transport chains 12 instead of the support wheels 50 suspended from the ceiling in the above-described embodiment. A compressed air supply hose 38 is rotatably connected, and a second compressed air supply hose 40 is rotatably connected to the first compressed air supply hose 38.

The rotary table 68 is provided with a support member 70 for supporting the second compressed air supply hose 40. The rotation of the rotary table 68 causes the second compressed air supply hose 42 to move along with the second compressed air supply hose 42. The rotation of the supply hose 40 is followed.

In this way, the second compressed air supply hose 40 does not hang from the ceiling, and can be made extremely clean. Work efficiency can be improved without disturbing the work.

Although not shown, first and second filler supply hoses can be connected to the rotary table 68.

The other configuration and operation are the same as those of the above-described embodiment, and the description is omitted.

The present invention is not limited to the above embodiments, but can be modified into various forms within the scope of the present invention.

For example, in the above embodiment, the case where compressed air is used as energy has been described. However, the present invention can be applied to the case where electricity or other energy is used.

Although a filler such as styrene foam has been described as a liquid material, the present invention can be applied to an adhesive or the like.

Further, although the second compressed air supply hose and the second filler supply hose are respectively provided one by one, a plurality of each may be provided.
