In the above-mentioned traveling trolley device, a conveyor device is usually provided on the trolley in order to smoothly transport loads between the trolley and the station, and a motor for driving the conveyor device,
Drive sources such as batteries were also mounted on the trolley. As a result, there are various restrictions such as the weight of the trolley becoming heavier and the loadable weight being restricted accordingly, and the need for the trolley to remain at a power supply location for a certain period of time in order to charge the battery on the trolley. has been added. In particular, an increase in the weight of the truck tends to lead to disadvantages such as a reduction in the speed of the truck in this type of traveling truck that uses friction to propel the vehicle.

Therefore, the present invention provides a novel method for loading and unloading cargo, which can make the traveling truck as described above lightweight, and can realize a traveling truck that does not require stopping during power supply.

Hereinafter, embodiments will be described based on the drawings.

In the figure, a truck 1 is supported on a cylindrical track 3 via wheels 2, and a drive shaft 4 is mounted along the track 3.

A pair of front and rear bearing housings 16 is supported at an intermediate position of the support guide 7 via a horizontal fulcrum pin 15 in a serpentine shape. A disk 9 is fixed. The friction disk 9 is inclined at a slight angle with respect to the surface of the drive shaft 4, so that it comes into contact with the outer peripheral surface of the drive shaft 4 at one point. Reference numeral 18 denotes a cam roller that engages with a stopping cam device 19 that will be described later, and the cam roller 18 is connected to the pair of bearing housings 1.
The arm 23 is provided at one end of an arm 23 which is provided through the connecting plate 21 connecting the connecting plates 6 and 6, and is supported on the side surface of one of the connecting plates 21 so as to be able to swing 22 freely. 11 is a spring for downward biasing of the friction disk 9, as described above;
A force is exerted between the tip of the support guide 7 and the receiving arm 8. Further, 24 is a pin fixed to the side surface of the support guide 7 via a bracket 25,
A tension spring 27 is stretched between the pin 24 and a pin 26 protruding from the lower surface of the truck 1, so that the entire support guide 7 supporting the friction disk 9 is always positioned toward the left in FIG. It is in force.

The traveling bogie 1 is configured as described above, and the support guide 7 is normally pulled to the left in FIG. contact, the rotational force of the drive shaft 4 is transmitted to the truck 1 as a propulsive force, the truck 1 moves forward, and the cam roller 18 is activated by the stop cam device 19.
The support guide 7 engages with the tension spring 27
When the friction disk 9 is moved to the right side as shown in FIGS. 1 and 2 against the tensile force of The cart 1 idles and stops. Next, the conveyor device 28 on the cart 1 will be explained.

In other words, the conveyor device 28 on the cart 1 is a roller conveyor without a driving source, consisting of six rollers 29 arranged in parallel.
A chain 32 is passed around the adjacent rollers so that all the rollers 29 are interlocked and rotated in unison.

In particular, a meshing gear 33 having a diameter smaller than that of the roller 29 is provided at the center of the axis of the roller 29 at the left end of the roller 29 in FIG.

Next, the station S will be explained. As shown in Figs.
Similar to the roller conveyor above, a chain 37 between adjacent rollers is wrapped around sprocket wheels 36 fitted and fixed at both ends so that all the rollers 35 are interlocked and rotate in unison. The roller 35 at the rear end is operatively connected to a drive motor 42 via sprocket wheels 38, 39 and a chain 41, and the roller 35 at the front end is
5 is provided with a meshing gear 43 having a diameter smaller than the roller 35 in the same manner as the meshing gear 33 described above.

A connecting gear 44, which is a transmission member, is provided in mesh with the meshing gear 43 in the following manner.

That is, a pair of levers 45 are rotatably supported by the shaft of the roller 35 at the front end.
A large-diameter connecting gear 44 is rotatably supported by a shaft 46 at an intermediate position of the lever 45, and a rod 47a end of a fluid cylinder 47 whose rear end is fixed to the frame 34 of the station S is connected to the tip of the lever 45. When the fluid cylinder 47 is expanded and contracted, the connecting gear 44 is constantly meshed with the meshing gear 43, and is in a state in which it projects forward of the station S (solid line in Figure 1) and a state in which it is sunk into the station S (in Figure 1). (dashed line).

Next, the stopping cam device 19 provided on the machine frame 48 of the track 3 and the stopper device 49 provided on the lower surface of the truck 1 will be explained.

As shown in FIGS. 1 and 2, the stop cam device 19 has pins 57 at the ends of arms 55 and 56, which are rotatable around support shafts 53 and 54, which have one ends 51a and 52a erected on the machine frame 48, respectively. , 58 are connected to each other, and the other ends 51b, 52b are connected to each other by a pin 59, and a fluid cylinder 61 for moving the cam bars 51, 52. The end 61a is connected with a pin 64 to the end of an arm 63 which is rotatable around a support shaft 62 erected on the machine frame 48.
3 intermediate pin 65 and the two cam bars 51,
It is connected to a pin 66 near the connection point of cam bar 52 by a short link plate 67, and when the fluid cylinder 61 expands and contracts, the connecting portion of the two cam bars 51 and 52 moves forward and backward toward the drive shaft 4, and the above-mentioned There are two states: a state in which the cam roller 18 is in contact with the connecting portion and is moved in a dogleg shape in plan view as shown in FIG. It is starting to shift across the board.

When the cam bars 51 and 52 are displaced in a dogleg shape, the cam roller 18 is moved and the support guide 7 is moved as described above, the position of the friction disk 9 is displaced, and the cart 1 is stopped. However, another arm 68 formed integrally with the arm 63 is protruded from the support shaft 62 and supported, and as the cam bars 51 and 52 are displaced in a dogleg shape, the arm 68 moves along the chain line in FIG. When the carriage 1 turns from the non-illustrated position to the position shown by the solid line, the stopper device 49 provided on the lower surface of the carriage 1 is stopped by the upper end of the arm 68, and the carriage 1
is designed to stop accurately at the desired stopping position. Reference numeral 69 is a regulation plate that regulates the rotation range of the arm 68.

The stopper device 49 on the trolley 1 side is connected to the bracket 7
A stopper block 7 is swingably supported by 1.
The stopper block 72 has a pair of protrusions 73 protruding from its base end, and swings only within a certain angle range, so that the tip of the stopper block 72 abuts and locks the tip of the arm 68. However, since this stopper block 72 is able to swing freely within a certain angle range as described above, it is possible for the carriage 1 to approach the arm 68 from any direction and stop. In other words, no matter which side surface of the arm 68 the stopper block 72 comes into contact with, the truck 1 always stops at a fixed stop position with respect to the arm 68. When the truck 1 is restarted, if the fluid cylinder 61 is contracted and the cam bars 51 and 52 are brought into a substantially straight line as described above, the arm 68 turns to the position shown by the chain line in FIG. It comes off and the trolley 1 is free to travel.

The traveling truck device and station of this example are configured as described above, and the truck 1 includes the stopping cam device 19, the arm 68, and the stopper device 4.
After stopping at the station S position at step 9, the cargo A is carried in and carried out in the following manner.

That is, when the fluid cylinder 47 is extended and the large-diameter connecting gear 44 is projected forward of the station S as shown by the solid line in FIG.
meshes with the meshing gear 33 of the roller 29 on the trolley,
Since the connecting gear 44 and the meshing gear 43 are always in mesh with each other as described above, the roller conveyor on the truck 1 and the roller conveyor on the station are interlocked and connected via the connecting gear 44.

Therefore, if the drive motor 42 is then rotated to drive the roller conveyor on the station S, the rollers 29 on the truck 1 will also be driven at once, and the load A will be carried out from the truck 1 onto the station S. It is. After the loading of load A is completed, the fluid cylinder 4
7 to retract the connecting gear 44 into the station S (as shown by the chain line in FIG. 1), the trolley 1 becomes free to travel again.

It will be obvious that loading the load from the station S onto the trolley 1 can also be carried out by rotating the drive motor 42 in substantially the same manner as described above.

Furthermore, in the above example, the conveyors on the trolley 1 and the station S were roller conveyors,
The conveyor may be another type of conveyor such as a belt conveyor, and the positions where the meshing gears 33, 43 are attached to the shafts of the rollers 29, 35 are not limited to the center of the rollers, but may be attached to the ends.

In any case, as described above, in this invention, the conveyor on the trolley is driven by the drive source provided at each station to carry in and carry out the cargo, so there are no motors, batteries, etc. on the trolley. There is no need to mount a driving source on the tower, which reduces the weight of the truck and eliminates the drawbacks mentioned at the beginning. Furthermore, since power supply is not required, the trolley can be kept in operation at all times. Further, since the roller conveyors of the station and the trolley are rotated by the same motor, they rotate synchronously, so that loading and unloading of loads can be carried out smoothly.
