BACKGROUND OF THE INVENTION
The present invention relates to a cart transport device, and more particularly, to a cart transport device in which improvements are made to the supply of energy and liquid material to a jig for work for assembling articles.
[0002]
[Background Art and Problems to be Solved by the Invention]
Generally, when assembling articles, an assembly line is installed in the factory, and jigs such as air drivers and air drills are suspended from the ceiling for each work area of the assembly line, and compressed against the jigs in each work area. Air is supplied.
[0003]
Each worker is positioned in the work area of the respective holding place, and the assembly work is performed using the jigs and tools suspended in each holding place.
[0004]
Also, when assembling relatively large items such as joinery, the assembly work is performed on the work carriage while the work carriage is transported and moved along the assembly line.
[0005]
However, when the jigs are suspended from the ceiling and compressed air is supplied to the jigs in this way, at least one air supply hose must be suspended in each work area. As the number increases, the number of air supply hoses to be suspended increases accordingly.
[0006]
Moreover, if there are multiple jigs and tools used in each work area, such as an air driver or air drill, the air supply hoses for the number of jigs and tools must be suspended in addition to the number of work areas. This increases the number of lines and becomes a complicated state, and further disturbs the work.
[0007]
In addition, when a jig such as a lifter that lifts the assembly is required for assembly work, even if compressed air is used as an energy source, a separate energy supply system is required, which complicates the structure. It is what will end up.
[0008]

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings.
[0025]
1-4 is a figure which shows the trolley | bogie conveyance apparatus concerning one embodiment of this invention.
[0026]
The carriage transport device 10 includes a transport chain 12 as a traveling tow body arranged on a line, and a plurality of, for example, eight work carts 14 connected to the transport chain 12. Aluminum building materials such as bathroom doors are sequentially assembled on the carriage 14.
[0027]
The transport chain 12 is composed of an endless roller chain wound around a pair of sprockets 16, and can be moved on a predetermined line by driving one of the sprockets 16 by a drive source (not shown). ing.
[0028]
Each work carriage 14 is connected to the transport chain 12 at a predetermined interval, and is movable on the line as the transport chain 12 moves.
[0029]
Specifically, as shown in FIG. 2, each work carriage 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.
[0030]
Further, as shown in FIGS. 2 and 3, the transport chain 12 is in a state in which the rollers 26 are connected by the upper and lower link plates 28. Further, an L-shaped mounting bracket 30 is attached, and the reinforcing member 22 of each work carriage 14 is fixed to the mounting bracket 30.
[0031]
The work carriage 14 can be moved around the floor along the transport chain 12 by a caster 24 without a track on a plane.
[0032]
In this way, the work can be efficiently performed with a small installation area without increasing the length of the line.
[0033]
The working carriage 14 is supplied with compressed air as energy of the jig 32 used for assembling the aluminum building material or the like, a filler as a liquid material, and the like. For example, two jig connection parts 34 are provided.
[0034]
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 a filling gun for filling a filler such as polystyrene foam into the aluminum building material is connected. Has been made possible.
[0035]
Thus, by providing the tool connection part 34 to each work carriage 14, it is possible to supply compressed air to the tool 32 simply by connecting the tool 32 to the tool connection part 34, Since the jig 32 is directly pulled out from the work carriage 14, it is possible to perform an efficient work without interfering with the work as compared with the case where it is suspended from the ceiling as in the prior art. Can supply compressed air to an air lifter or the like without using a separate compressed air supply system, and the structure can be simplified.
[0036]
The compressed air includes an air compressor 36 as an energy supply source, a first compressed air supply hose 38 and a second compressed air supply hose 40 as an energy supply system, a compressed air distribution hose 42 as an energy distribution system, The tool hose 44, the cushion tank 46, and the connection hose 48 are supplied to one jig connecting portion 34 of each work carriage 14.
[0037]
The first compressed air supply hose 38 is connected to a support wheel 50 that is suspended from the air compressor 36 and supported on the ceiling.
[0038]
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 rotatably held together with the support wheel 50 on the outer periphery of the support wheel 50. In addition, the other end is rotatably connected to the compressed air distribution hose 42 via a coupler (not shown).
[0039]
The compressed air distribution hose 42 is formed in an endless shape, and as shown in FIGS. 2 and 4, the compressed air distribution hose 42 is partially engaged at a predetermined interval via a locking member 52 on the traveling center line of the link plate 28 of the transport chain 12. It is stopped so that it can rotate with the conveying chain 12.
[0040]
In this way, by allowing the compressed air distribution hose 42 to travel with the transport chain 12, the relative positional relationship between the work carriage 14 and the compressed air distribution hose 42 can be kept constant.
[0041]
Moreover, by locking the compressed air distribution hose 42 on the travel 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 is always constant even when passing through the sprocket 16. Therefore, expansion and contraction of the compressed air distribution hose 42 can be suppressed.
[0042]
Furthermore, since the compressed air distribution hose 42 is partially locked to the transport chain 12 and is open at a midway position, maintenance is easy.
[0043]
The compressed air distribution hose 42 is connected to the cushion tank 46 through the pull-in hose 44, and the compressed air is temporarily stored in the cushion tank 46, and the compressed air stored in the cushion tank 46 is stored in the connection hose 48 and the control hose. The compressed air can be supplied to the jigs 32 through the tool connecting portion 34.
[0044]
Thus, by supplying the compressed air to the jig 32 through the cushion tank 46, the compressed air can be reliably supplied from one compressed air distribution hose 42 to the plurality of work carts 14.
[0045]
In addition, the number of second compressed air supply hoses 40 is reduced and the configuration is simplified, and the work efficiency is improved by eliminating the second compressed air supply hose 40 and the compressed air distribution hose 42 in the work area of the worker 66. Can be improved.
[0046]
In addition, since the 2nd compressed air supply hose 40 and the compressed air distribution hose 42 are made movable, it is desirable to form with an elastic material or a flexible material.
[0047]
The filling material passes from a filling material stock tank 54 as a liquid material supply source through a supply pump 56, and then a first filling material supply hose 58 and a second filling material supply hose 60 as a liquid material supply system, a liquid material distribution system. Are supplied to the filler distribution hose 62, the pull-in hose 64, and the other jig connecting portion 34.
[0048]
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.
[0049]
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 rotatably held together with the support wheel 50 on the outer periphery of the support wheel 50. In addition, the other end is rotatably connected to the filler distribution hose 62 via a coupler (not shown).
[0050]
Like the compressed air distribution hose 42, the filler distribution hose 62 is formed in an endless shape, and on the traveling center line of the link plate 28 of the transport chain 12, together with the compressed air distribution hose 42, via a locking tool 52. It is partially locked at a predetermined interval so that it can rotate with the transport chain 12.
[0051]
The pull-in hose 64 is directly connected to the other jig connecting portion 34 from the filler distributing hose 62, and allows the filler pumped by the supply pump 56 to be directly supplied to the jig 32 such as a filling gun.
[0052]
Since the second filler supply hose 60 and the filler distribution hose 62 are movable like the second compressed air supply hose 40 and the compressed air distribution hose 42, an elastic material or a flexible material is used. It is desirable to be formed by.
[0053]
In this way, in addition to energy such as compressed air, the filler is simplified from the filler stock solution tank 54 to each work carriage 14 via the first and second filler supply hoses 58 and 60 and the filler distribution hose 62. Thus, it can be supplied in a configuration that does not get in the way, and work efficiency can be improved.
[0054]
FIG. 5 is a diagram showing a carriage transport device according to another embodiment of the present invention.
[0055]
In this embodiment, instead of the support wheel 50 suspended from the ceiling in the above embodiment, a rotary table 68 is disposed in the floor space between the transfer chains 12, and the first compressed air is supplied to the rotary table 68. A hose 38 is rotatably connected, and a second compressed air supply hose 40 is rotatably connected to the first compressed air supply hose 38.
[0056]
In addition, the rotary table 68 is provided with a support member 70 that supports the second compressed air supply hose 40, and the second compressed air supply hose 40 accompanying the movement of the compressed air distribution hose 42 by the rotation of the rotary table 68. It is made to follow the rotation of.
[0057]
In this way, the second compressed air supply hose 40 does not hang from the ceiling, and can be configured to be extremely clean. The second compressed air supply hose 40 obstructs the work. It is possible to improve the work efficiency.
[0058]
Although not shown, it is also possible to connect the first and second filler supply hoses to the rotary table 68.
[0059]
