Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device equipped with an actuating device operated by pressure fluid, the purpose of which is to transport a conveyor device that moves beyond the range that can be supplied with pressure fluid by a flexible pressure fluid supply pipe. It is an object of the present invention to enable pressure fluid to be used as a power source for propulsion of a trolley, such as a trolley of a trolley conveyor.

An embodiment of the present invention will be described below based on illustrative drawings. In Figs. This is a dual-purpose high-pressure air pipe, and both are connected by connecting members 3 at appropriate intervals and are installed at a predetermined height by brackets 4.

Reference numeral 5 denotes a transport vehicle, which has a pair of front and rear wheels 6, 7 that ride on the guide rail 1, and two pairs of left and right wheels 8, 9, front and rear, which sandwich the high-pressure air pipe 2. A conveyed object clamping means 11 is provided via an air-driven elevating means 10.

As shown in FIGS. 3 and 4, the high-pressure air piping 2 has an opening 12 continuous in the length direction at the bottom, and an elastic sealing material 13 is attached to the inner surface of the high-pressure air piping 2. The portions 14 overlap each other at the position of the opening 12 so as to close the opening 12, thereby forming a sealed high-pressure air passage 15 inside the pipe 2.

Reference numeral 16 denotes a high-pressure air intake means provided in the transport vehicle 5, which includes a pair of front and rear piston portions 17 that are slidably fitted into the high-pressure air passage 15 in the length direction thereof, and both piston portions 17 are placed at their center positions. and the opening 1 of the piping 2 from the center of the piston rod 18 to the elastic seal control 30 passing between both free sides 14.
The piston part 17 and the piston 19 are connected to each other so as to protrude downward from the piston part 2, and the pillar part 19 is fixed to the conveyor truck 5. An air intake passage 20 provided in the rod portion 18 is communicated with a control means 22 attached to the side of the carrier vehicle 5 via a passage 21 provided in the support portion 19.

Reference numeral 23 denotes a roller fitted to the support portion 19, and both side portions 14 of the elastic sealing material 13 are swept upward by this roller 23.

The control means 22 uses the air taken in to drive the wheels 7 through an air motor 24 capable of forward and reverse rotation, and the elevating means 10.
It has a built-in switching valve that supplies timely supplies to an air motor 25 capable of forward and reverse rotation that drives the 2B , 29 and 30 are switching operation levers for these switching valves.

Further, 31, 32, and 33 are air supply pipes.

Next, the method of use and effect will be explained.

If high-pressure air is supplied into the high-pressure air piping 2 from multiple locations or one location along its length, the air will be transferred to the transport vehicle 5.
passage 20.21 in the high pressure air intake means 16 of
It is incorporated into the control (goods) means 22 through.

When air is supplied to the air motor 24 via the piping 31 by this control (2) means 22, the wheels 7 are driven to rotate in the normal direction, and the carrier 5 is guided by the rails 1 and piping 2 while traveling. Become.

As the transport vehicle 50 travels, the support 19 of the high-pressure air intake means 16 moves across the circumferential side 14 of the elastic sealing material 13 in the left and right upward directions via the rollers 23, and integrally with the support support, both the front and rear pistons 17 is air passage 1
5, the section where the support section 19 separates both free sides 14 of the elastic sealing material is blocked off from the high-pressure air passage 15 to prevent air in the passage 15 from leaking from the side of the support section 19. is prevented.

When stopping the transport vehicle 5 or moving it backwards, the operating lever 28 of the control means 22 is operated by a fixed cam or movable operating means provided on the side of the traveling route to cut off the air supplied to the air motor 24. or air motor 2
It is sufficient to switch the switching valve to co-supply air in the direction of reversing 4.

When the transport vehicle 5 is stopped, both the front and rear piston portions 170
Since both sides are communicated through the passage 20, no thrust is applied to the carrier vehicle 5.

Further, a plurality of transport vehicles can be run in the same manner as above.

When loading and unloading the transported objects 34 while the transport vehicle 5 is stopped or running, the operating levers 29 and 30 of the control means 22 are operated by a fixed cam or a movable operating means on the side of the route. The driving air motor 25 of the elevating means 10 may be rotated forward or reverse to raise or lower the clamping means 11, and the cylinder 27 of the clamping means 11 may be driven to open or move the clamp claw 26 closer.

The present invention can be realized as described above, and it is possible to drive various actuating devices (not limited to those in the embodiments) provided on the transport vehicle with pressure fluid such as high-pressure air, and furthermore, the transport vehicle and the pressure fluid Instead of connecting the source with flexible piping, pressure fluid is constantly taken in continuously through pressure fluid intake means (not limited to the one in the example) from pressure fluid piping arranged along the travel route. , the travel route of the transport vehicle can be laid out arbitrarily.

In addition, unlike conventional trolley conveyors, there is no need to make the traveling route endless (furthermore, it is also easier to run the transport vehicle at high speed).
