Description

[Detailed Description of the Invention] There is a trolley drive system in which the trolley is driven by pressing a friction wheel onto a drive shaft disposed along the running path of the trolley.

In such a bogie drive system, the applicant first presses a friction disk that rotates around a rotation axis substantially perpendicular to the drive shaft against the drive shaft, and increases the contact surface between the friction disk and the drive shaft. An application has been filed for a bogie drive device that can obtain a large frictional force, that is, a running force.

That is, in FIG. 1, reference numerals 1 and 1 indicate running rails, and the bogie 2 is supported by the running rails 1 via wheels 3, 3.

Reference numeral 4 denotes a drive shaft disposed along the traveling rail 1, which is perpendicular to the axis of rotation of the drive shaft 4, and attached to a support shaft 5 which is fixedly suspended from the trolley 2, and which is movable along the support shaft 5 and is equipped with a spring at the bottom. a bracket 6 that is biased and rotatable with respect to the support shaft 5;
is supported, and a disk 8 is fixed to the lower end of the rotating shaft 7 rotatably supported on the bracket 6 via a bearing, at a slight angle with respect to the axis of the drive shaft 4. A ring-shaped friction disk 9 made of synthetic resin, hard rubber, or the like is fixed.

Further, in FIG. 2, 10 is a spring that urges the bracket 6 to pivot clockwise around the support shaft 5, and 11 is a stopper of the bracket 6. The status indicates the normal status of the trolley.

12.13 has a cam roller 14.15 at the tip, and the cam rollers 14, 15 are engaged with cam plates 16.17 provided at predetermined locations on the bogie running path by arms fixed to the bracket 6, and the bracket 6 supports them. The truck rotates around the shaft 5, and when the rotation axis 7 of the friction disk reaches the axis of the drive shaft 4, the truck stops.

That is, in FIG. 3, A shows the normal running state of the truck, and as the drive shaft 4 rotates in the direction of the arrow 18, the friction plate 9 contacts the drive shaft 4 at the support shaft 5 portion and moves at the tangential speed shown by the arrow 19. The cart rotates and travels in the direction of arrow 21 with the magnitude of the axial component 20 of drive shaft 4 shown by arrow 19 .

When the drive shaft 4 rotates in the direction indicated by the dotted arrow 22, the truck 2 travels in the direction indicated by the dotted arrow 23.

The bracket 6 rotates by the cooperation of the cams 16 and 17 and the arms 12 and 13, and in the open state, the friction disc 9 is rotated by the drive shaft 4.
Since the bogie 2 rotates at a tangential speed perpendicular to the axis of the drive shaft 4 as indicated by an arrow 24 at the point of contact with the bogie 2, the running force of the bogie 2 becomes zero and it stops.

The applicant previously filed an application for a traverse device 27 as a means for transferring such a drive cart from one drive shaft 25 shown in FIG. 4 to another drive shaft 16 of a separate system.

That is, in FIGS. 5 and 6, the traverser 27 has a frame 30 placed on rails 28, 28 via wheels 29, 29, and a friction mechanism provided on the trolley 2 that presses against the traverser drive shaft 31. It is composed of a friction disk 32 similar to the disk 9, a drive shaft 33 for loading and unloading the cart 2 to be transferred onto the traverser 27, and a stop device 34 for the cart transferred along the drive shaft 33. There is.

That is, the frame body 30 is provided with rails 36 and 36 at the same height as the extension of the travel rail 35 at the bogie receiving position A in FIG.

Reference numeral 37 denotes a motor for the drive shaft 33, which rotates the drive shaft 33 in forward and reverse directions via a chino 38.

Furthermore, a friction disk positioning device 34 provided on the traverser 27
is engaged with the arm 12 shown in FIG. 2 in the bogie receiving position, rotates the friction disk 9 about the shaft 5, and stops the running of the bogie.The cam plate 39 is moved to the lever 40. 4
1, the lever 45 has a lever 45 that rotates parallel to the shafts 43, 44 of the fixed frame 42 via the cam plate 39.
The cam plate 39 is integrally supported by a shaft 43 with a lever 40 connected to the drive shaft 33, and a roller 46 at the end of the lever 45 engages with another cam plate 47 fixed at a fixed position on the ground side. Turn in the direction approaching.

Further, reference numeral 48 and 49 in the fourth figure indicate a cam plate for stopping the traverser 27, which is provided on the side of the traverser drive shaft 31 so as to be able to come into contact with the rollers 52 and 51 of the traverser 27.
The traverser is stopped at a predetermined cart discharge position.

In such a drive cart transfer by the traverser, at the cart receiving position A in FIG. 4, the cart running along the drive shaft is transferred from the drive shaft 25 to the drive shaft 33 on the traverser side, and is brought to the cart stopping position as shown in FIG. 6. An arm on the truck side (FIG. 2, 12) engages with a certain swing cam plate 39, and the friction disk 9 on the truck side rotates to position the truck at the truck stop position, and the truck stops on the traverser.

In this case, the arm 12 initially comes into contact with the inclined surface 39a of the swing cam, and acts so that the truck stops when the arm 12 reaches the parallel surface 39b of the cam plate 39 while reducing the traveling speed of the truck.

Therefore, when the trolley 2 is running at high speed, it must have a sufficient deceleration range in order to stop at a fixed position on the traverser, and if it stops suddenly, the cargo on the trolley will collapse and fall to the stoppers 53 and 54 on the traverser. There is a risk of accidents such as collisions.

The present invention was made to solve the above-mentioned disadvantages, and will be explained below with reference to the drawings.

In FIG. 6, the above-mentioned disadvantage is solved by fixing an auxiliary inclined plate 55 on the ground side as an extension of the inclined surface 39a of the rocking cam plate 39 that should ensure the deceleration range of the bogie 2. be.

That is, if the inclined surface 39a of the swing cam plate 39 installed on the traverser 27 is made to protrude from the side surface of the traverser, the length of the deceleration region can be increased, but the protruding portion becomes an obstacle when the traverser is moving. , it can be considered that the slope is separated into the traverser side and the ground side.

Therefore, the auxiliary inclined plate 55 must be fixedly installed at a position extending from the inclined surface 39a while the swing cam 39 is positioned at the trolley stop position.

That is, it is preferable that the arm contact surfaces 39a, 55a are in a continuous straight line.

In addition, instead of fixing the auxiliary inclined plate 55 on the ground, it is provided so that it can move in and out along the inclined part 39a of the swing cam plate 39 on the traverser side, and is recessed into the inclined surface 39a while the traverser is running, so that it can be placed at the bogie receiving position. It is also possible to make it movable so that only the part protrudes.

Therefore, in the past, there was no auxiliary inclined plate and the trolley 2 was decelerated only after it was transferred onto the traverser 27, but in the present invention, at the trolley receiving position of the traverser,
The contact length of the arm 12 for actuating the friction disk 9 of the truck with the inclined surface 39a can be increased, and the truck 2 is decelerated from the point when it approaches the traverser 27 by a predetermined distance, and the deceleration travel distance of the truck can be increased, so that the truck can be moved smoothly. It is possible to receive the cargo, and it is possible to prevent the occurrence of impacts such as collapse of cargo on the cart.

In addition, the stop position of the bogie is not simply provided at the end of the normal running track 35 of the bogie 2, that is, the end of the track 35 facing the traverse track 28 of the traverser, but the inclined surface is particularly the inclined surface of the swing cam plate 39. Since the auxiliary inclined plate 55 is provided in a continuous straight line, the bogie 2 does not come to a complete stop at the end of the running track 35, that is, just before transferring to the traverser 27, and is continuously and moderately decelerated. If the cart 2 is transferred onto the traverser 27 and completely stopped by the stop device before the traverser 27, extra time and energy are required to start the cart 2 again, but the reduction gear of the present invention eliminates the above-mentioned extra It does not require a lot of time or energy.
