Description

[Detailed description of the invention] The present invention is a floor conveyor used in assembly work lines, etc., which includes a workpiece support means and a work deck that is continuous along the conveyance path on the floor and road surfaces. The present invention provides a floor conveyor.

An embodiment of the present invention will be described below based on the attached illustrative drawings. Reference numeral 1 denotes a cart, and a workpiece supporting means 2 is provided in the center.
It has a work deck 3 around it, and the bottom is provided with swivel wheels 4 at four locations on the front, back, left and right.
There are tow pins 5 at the front and rear of the left and right sides that can be raised and lowered,
6 is provided.

Further, on the other side, a current collector 7 is provided facing outside the premises for supplying power to local lighting equipment for work (not shown).

The workpiece supporting means 2 is supported by a guide rod 8 and is raised and lowered by a suitable cylinder unit 9 such as a two-stage ram cylinder, and can also be moved back and forth and left and right by a front and rear horizontal guide rod 10 and a left and right horizontal guide rod 11. A workpiece support stand 12 is provided.

Reference numeral 13 denotes a pit formed along the conveyance path, and the central part is provided with a recess 14 in which the guide rod 8 and cylinder unit 9 protruding from the bottom of the truck 1 move. A guide rail 15 for supporting and guiding the wheel 4 is provided, and furthermore, a pair of left and right guide rails 17 for guiding roller portions 16 provided on the toe pins 5 and 6 are provided near the bottom and sides, and a pair of left and right guide rails 17 for guiding roller portions 16 provided on the toe pins 5 and 6, a pair of left and right guide rails 20 for supporting and guiding a trolley 19 equipped with a pusher 18 for backing up the trolley 19;
A driving means 22 connected to and separated from the driving chain 21 that moves between the guide rails 20 is disposed, and at a position near the other side of the bottom, a power supply rail 23 on which the current collector 7 slides is installed in the necessary route area. has been done.

In this pit 13, the work deck 3 of the trolley 1 is connected to the floor surface 24.
The depth is such that it becomes the same as the road surface.

The pushers 18 are arranged at appropriate intervals so that the front and rear carts 1 driven by each pusher 18 approach each other as shown in FIG.
is covered by a cover plate 26 that is connected from the rear end of each truck 1 so as to cover the front end of the rear truck 1, and the gap 27 between each truck 1 and the floor surface 24 is
It is covered by a cover plate 28 which is continuously arranged so as to cover the floor surface 24.

Incidentally, the gap 25 can also be covered by two cover plates that are connected from the front and rear carts 1 so as to overlap each other.

Reference numeral 29 denotes an air-hydro booster unit mounted on the trolley 1, which can be controlled by air by connecting the air supply pipe on the fixed side to the air supply port 30 and supplying pressurized air before work at certain points on the trolley route. It is possible to obtain a hydraulic output, and the cylinder unit 9 in the work supporting means 2 is driven by this hydraulic output.

31 is the control valve, and a manual operation lever 32
It is equipped with

A workpiece is set on a workpiece support stand 12 in the workpiece support means 2 of each cart 1.

As the trolley 19 is moved forward by the drive cheno 21, the pusher 18 backs up the tow pin 5 of each truck 1, and each truck 1 is made to run continuously within the pit 13.

At this time, the direction of each truck 1 is regulated by roller portions 16 of the front and rear tow pins 5.6 and guide rails 17.

The worker is supported across an article supplied by an overhead trolley conveyor or the like, such as the body of a car, and a workpiece on each trolley 1, for example, workpiece support means 2 on the front trolley and workpiece support means 2 on the rear trolley. The work of connecting the chassis unit to the chassis unit can be performed on the work deck 3 of each truck 1.

At this time, the height of the workpiece on the workpiece support means 2 can be freely adjusted by operating the operating lever 32 and operating the cylinder unit 9 with the hydraulic pressure supplied from the air bite lobster unit 29. Note that the pressurized air supplied to the air-hydro booster unit 29 can be obtained by a baby compressor mounted on the trolley 1.

In this case, it is sufficient to provide a power supply means to the compressor, and the work deck 3 has openings for raising and lowering the tow pins 5 and 6 and maintenance and inspection of the drive means 22, and an opening for the collector 7.
It is convenient to provide openings for maintenance and inspection of the power supply rail 23 and to provide opening/closing lids for these openings, since these necessary operations can be performed from the top of the cart.

The floor conveyor of the present invention can be implemented and used as described above, and there is no need to provide a slat conveyor for workers separately from a transport vehicle for supporting workpieces, and moreover, it is possible to provide workpiece support means on the slats of the slat conveyor. As a result of lowering the lowering limit height of the workpiece support 12 as in the case where the workpiece support table 12 is installed, the conveyor pit that also accommodates the lower slat return path becomes very large due to the presence of the cylinder unit that protrudes long below the slats. There is no inconvenience such as the pit becoming too deep and the cost of building it becoming extremely high.

In other words, although workers can easily and safely work on a work deck with continuous floor and road surfaces, similar to equipment in which workpiece support means are provided on the slats of a slat conveyor, Therefore, the entire device including the cost of constructing the pit can be manufactured at low cost.
