Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a capsule uncoupling device for capsule transportation.

As is well known, capsule transportation is a method of transporting cargo by moving capsules through pipelines using air or water pressure.

In this capsule transportation, at the time of unloading or loading,
Capsules transported independently are once connected to each other.

Therefore, after unloading or loading, it is necessary to release the connection and separate each capsule.

However, conventionally, the above-mentioned uncoupling operation was performed by stopping the capsule, which caused the problem of low capsule transportation efficiency.

The present invention has been made in view of the above circumstances, and its purpose is to provide a capsule uncoupling device for capsule transportation, which allows the uncoupling operation to be performed while the capsule is traveling.

An embodiment of the present invention will be described below with reference to the drawings.

Similarly, on the upper surface of 12, chain guides 54 b, 54
b, 54 C, 54C are sprocket wheels IOA
They are installed on the underside of the endless chain 12.12 between the sprocket wheel 9 and the sprocket foil IOB, respectively, to prevent the endless chain 12.12 from coming off the sprocket foil ( (See Figure 8).

The carriages 45 are arranged on the endless chain 12.12 at intervals corresponding to the vehicle length Ll of the capsules 3 and at intervals corresponding to the length L2 of the connecting portion between the capsules 2.

That is, as shown in FIG. 1, the capsule 3C is
The carriage 45b that supports the rear bottom plate 48 is arranged at a distance of Ll, and the carriage 45b and the carriage 45C that supports the front bottom plate 47 of the capsule 3D following the capsule 3C. are arranged with an interval of L2.

The length of the endless chains 12, 12 is L1+L
The length is set to be an integral multiple of the length of 2, so that the transport vehicle 45 and the capsule 3 are not out of phase.

Furthermore, as shown in FIGS. 4 and 5, rails 49 are provided on the lower surface of both ends of the transport vehicle 45, extending from the entrance end to the exit end of the unloading section 2 in parallel with the endless chain 12, 12. Wheels 50.50 rolling on .49 are provided.

Further, a support roller 51 is provided at the center of the upper surface of the transport vehicle 45.
There are two on the left and right.

The width of this support roller 51 is equal to the width of the slings 1-52a and 5 formed on the bottom surface of the pipeline 1 on the side of the entrance and exit of the unloading section 2.
2b, and when the transport carriage 45 is carried to the entrance end side of the unloading section 2 by the endless chain 12. Before moving from the bottom of the pipeline 1 to the unloading section 2, the front bottom bracket 47 or the rear bottom bracket 48 is supported, and the conveyor truck 45 is moved to the exit end side of the unloading unit 2 by means of endless chains 12, 12. When carried, the support roller 51 enters the slit 52a and supports the front bottom plate 47 or the rear bottom plate 48 until the tire 29 of the capsule 3 lands on the bottom surface of the pipeline 1 through the notch 53. is being done.

Therefore, when the capsule 3 moves from the pipeline 1 to the inlet end of the unloading section 2 or from the outlet end of the unloading section 2 to the pipeline 1, there is a risk that the tire 29 will fall into the unloading section 2. There is no.

Note that the slits 52a and 52b are sandwiched between the tire 29 and the tire 29.

There is no fear of falling to 52b.

Pipeline 1 on the exit side of the unloading section 2 (left side in Figure 1)
A slit 14 is formed along the length direction approximately at the center of the bottom surface.

A connection release device 15 of the present invention is installed at a position substantially directly below this slit 14.

This uncoupling device 15 is connected to a sprocket wheel 16 .

It runs parallel to the slit 14 within a range of 1.

Further, the sprocket wheel 16 is connected to the rotating shaft of the sprocket wheel 9 of the conveying device 5 via a transmission belt synchronizing means 22 so as to rotate.

Further, the circumferential length of the endless chain 19.19 is set to be an integral multiple of the unit length between the connecting devices 6 of the capsule 3, and the release cam member 20 is set to be an integral multiple of the unit length between the connecting devices 6 of the capsule 3. They are arranged with an interval corresponding to a unit length between them.

Further, the endless chain 19.19 runs at the same speed as the capsule 3 on the endless chain 12 when the rotation of the sprocket wheel 16 is transmitted from the drive device 11 via the sprocket wheel 9 and the transmission belt 22. It is done like this.

Therefore, in the device of the slit 14, if the release cam member 20 and the release roller 7 of the coupling device 6 are set in advance so as to be located on the same vertical line, the release roller 7 as the capsule 3 travels. When the release roller 7 is positioned above the rear end of the slit 14, the release cam member 20 comes to a position substantially directly below it, and the release roller 7 and the release cam member 20 run toward the front end of the slit 14 at the same speed. I will do it.

The release cam member 20 is an endless chain 19.1.
9, a rail 5 is provided parallel to the endless chain 19° 19 from the inlet end to the outlet end of the slit 14.
The main body 24 is fixed via a wheel cam 56.56 that rolls on a sprocket wheel 16.
7) and the main body 2.
A rectangular plate-shaped cam plate 26 is provided at the upper end of the support rod 25 protruding from the upper surface of the main body 24, and a metal fitting 27 is rotatably provided at the lower end of the support rod 25 protruding from the lower surface of the main body 24. It is composed of a cam roller 28.

The support rod 25 and the cam plate 26 are attached to the sleeve I.14.
It is sized to fit inside.

Further, the cam roller 28 rides on the dog 21 when traveling between the sprocket wheels 16 and 17.

Further, the dog 21 is connected to the sprocket wheel 17.
The structure is such that it is inclined upward from the top toward the sprocket wheel 16 side (in the direction of movement of the capsule 1).

Then, when the cam roller 28 rides on the dog 21, the support rod 25 and the cam plate 26 move upward with respect to the main body 24 and enter the pipeline 1 through the slit 14, and the dog 21 When the top of the coupling device 6 is reached, the cam plate 26 lifts the release roller 7 of the coupling device 6 upwards.

Note that, since the slit 14 is formed more centrally than the tire 29 provided in the capsule 3, the tire 29
There is no fear that it will become depressed.

Further, the support rod 25 has an upper half having a larger diameter and a lower half having a smaller diameter, and there is a stepped portion between the upper half and the lower half.

Next, the connecting device 6 will be explained with reference to FIGS. 2 and 3. A hydraulic buffer cylinder 30 is provided at the connecting end of one capsule 3A, and a piston rod 31 of this hydraulic buffer cylinder 30 is provided. A substantially hemispherical connecting protrusion 33 is provided at the distal end of the holder with a locking step 32 interposed therebetween.

Further, a hydraulic buffer cylinder 34 is similarly provided at the connecting end of the other capsule 3B, and a connecting hole 36 into which the connecting protrusion 33 is loosely inserted is formed at the tip of the piston rod 35 of the hydraulic buffer cylinder 34. A connecting base plate 37 is provided.

A pull-out prevention member 38 is provided on the front surface of the connecting base plate 37.

This removal preventing member 38 includes a pair of clamping rods 39.39 that lock onto the locking step portion 32, and a pair of link pieces 40.40 that operate the clamping rods 39.39 to move toward and away from each other. , the above-mentioned release roller 7 suspended from the lower ends of the pair of link pieces 40, 40, and a coil spring 41, 41 provided between the pair of clamping rods 39, 39. .

When connected, the elastic force of the coil springs 41, 41 maintains the locked state between the pair of clamping rods 39, 39 and the locking step 32, and the connecting protrusion 33 is pulled out from the connecting hole 36. is prevented, and when the connection is released, the release roller 7
When a pressing force is applied to lift the link piece 40 upward, the link piece 40
．． 40 resists the elastic force of the coil springs 41.41 to separate the pinching rods 39.39 from each other, and the pinching rods 39.3
9 and the locking step portion 39 are released.

Note that the coupling device 6 is not limited to the one shown in FIGS. 2 and 3, but may have a structure that can release the coupling when a pressing force is applied from the outside. .

Next, the operation of the connection disconnection device having the above configuration will be explained.

In FIG. 1, a capsule 3D is a capsule immediately before entering the unloading section 2. A capsule 3C is a capsule traveling on the unloading section 2, and a capsule 3A is a capsule immediately after leaving the unloading section 2.

These capsules 3A, 3・B, 3C. 3D are connected to each other by a connecting device 6 and are running at a constant speed, but they are not connected before entering the unloading section 2. They each run independently in the pipeline 1 before entering the unloading section 2. are sequentially connected.

Although not shown in FIG. 1, another capsule is running from behind the capsule 3D at a faster speed, and just before the capsule 3D enters the unloading section 2, it collides with it and becomes connected. It has become.

Note that the impact at the time of a rear-end collision is also transmitted to the capsule 3C traveling in front via the coupling device 6, but is absorbed by the front hydraulic shock absorber cylinder 34 of the capsule 3D and the rear hydraulic shock absorber cylinder 30 of the capsule 3C.

In addition, capsule 3. are individually determined by the carriages 45a and 45b, and the collision reaction force prevents the carriage from moving forward suddenly.

That is, the rear-end collision reaction force is transmitted from the transport vehicles 45a, 45b to the endless chain 12.12, but the endless chain 12.12 is transmitted to the chain guides 54a, 54a.
, 54b, 54b, 54C, and 54C, the rear impact reaction force is transmitted to the transmission of the drive device 11 without coming off the sprocket wheel.

The rear-end collision reaction force only works in the direction of reducing the driving force from the low-speed side of the transmission to the high-speed side (motor side), so it does not suddenly speed up the rotation.

In addition, the tire 29 installed on the capsule 3C is connected to the pipeline 1.
The capsule 3C is in contact with the inner surface of the upper part and both sides of the capsule 3C, and the capsule 3C does not come off from the transport carriages 45a, 45b due to this rear-end collision reaction force, and there is virtually no trouble in attaching the capsule 3C.

After a short period of time has elapsed from the state shown in FIG. 1, the capsule 3D gets onto the transport device 5 from the pipeline 1.

That is, when the tire 29 at the front end of the capsule 3D is located at the entrance end of the unloading section 2, the support roller 51 of the transport vehicle 45C protrudes from the sleeve 52b, and the capsule 3
The front bottom plate 47 of D is supported by the support roller 51.

In this case, the front end of the capsule 3D is
5o.

Then, as time elapses, the rear bottom metal 11 of the capsule 3D is also supported by the transport vehicle 45d (
The state is similar to that of the capsule 3C shown in FIG. 1).

On the other hand, the capsule 3C is transported between the transport vehicle 45a and the transport vehicle 4.
It is running on chute 4 supported by 5b.

When the capsule 3C comes to a position almost directly above the chute 4, the bottom cover of the capsule is opened by the bottom cover opening device 43, and the capsule 3C is opened.
Cargo C is unloaded.

Further, the bottom lid of the capsule 3B which has already been unloaded is closed by the bottom lid closing device 44 as shown in FIG.

Capsule 3 moved by conveyance device 5 and left unloading section 2
A, 3B, . . . advance through the pipeline 1 while being connected to each other by a connecting device 6.

On the exit side of the unloading section 2, an endless chain 19 is running at the same speed as the capsules 3A, 3B, etc., and is used to release the coupling device 6 provided between the capsule 3A and other capsules 3B following it. When the roller 7 comes to the rear end of the slit 14, the endless chain 19 causes the release cam member 20 to run almost directly below it, and then the release roller 7 and the release cam member 20 run together along the slit 14. do.

When the cam roller 28 of the release cam member 20 rides on the dog 21, the support rod 25 and the cam plate 26 of the release cam member 20 are lifted upward, and the pipe is moved from the slit 14 to the center of the slit 14. Go inside line 1.

When the cam roller 28 reaches the top of the dog 21, the cam plate 26
moves to the uppermost position and lifts up the release roller 7.

Then, as shown in FIG. 3, the coil spring 41.
The pinching rods 39 and 39 are separated from each other by the link pieces 40 and 40 against the elastic force of the link pieces 41 and 41, respectively.

At this time, the capsules 3A and 3B, which are traveling in front, are disconnected from each other by a suction blower (not shown), and are in a state before entering the unloading section 2.

On the other hand, the cam roller 28 that has climbed onto the top of the dog 21 immediately gets off the dog 21.

As a result, the support rod 25 and the cam plate 26 descend due to their own weight and exit from the pipeline 1.

According to the above embodiment, the endless chain 1
The sprocket wheel 16 that runs the sprocket wheel 9 is the conveyor device 5
The endless chain 19 is set to be an integral multiple of the unit length of the capsule 3, and the release cam member 20 is set to the unit length of the capsule 3. They are arranged on the endless chain 19 at intervals corresponding to .

Therefore, even if the running speed of the endless chain 12, that is, the running speed of the capsule 3 changes, it is possible to synchronize the release cam member 20 and the release roller 7 of the coupling device 6 without any operation. Become.

Moreover, since the support rod 25 and cam plate 26 of the release cam member 20 come out from inside the pipeline 1 after the connection is released, there is no risk of interfering with the running of the subsequent capsule 3B.

In the above embodiment, each capsule 3 can be separated, but the release cam member 20
By changing the spacing between the capsule trains, it is also possible to disconnect two or more capsule trains.

Further, although the case where the device of the present invention is installed on the exit side of the unloading section 2 is shown, it may be installed on the exit side of the cargo loading section in the pipeline.

In that case, in the method of loading the cargo from the top of the capsule, the upper notch of the pipeline 1 should be located at the position of the capsule 3B, not at the position of the capsule 3C, which has a large impact when the capsules are connected in Fig. 1. However, the lower notch is not necessarily required, and the slit 52 may simply be provided over the length of the loading section, and the support rollers 51 of the carrier vehicle 45 may protrude from the slit 52 to support the capsules.

Similarly, if the device of the present invention is installed in a location other than the cargo handling section, the lower cutout is not necessary as described above, and the slit 52 may simply be provided (see FIG. 7).

As explained above, according to the present invention, the connection can be released while the capsule is running without stopping.

Therefore, by equipping the uncoupling device of the present invention on the exit side of the unloading section, loading section, etc., the efficiency of transporting capsules can be significantly improved.

Moreover, the uncoupling device of the present invention has an endless traction member 1
9, a cam plate 26 is supported by the support rod 25 and is provided movably in the axial direction of the support rod 25 within a vertical plane;
Due to the action of the dog 21 tilted upward in the direction of travel of the capsule vehicle 1 and the moving force of the support rod 25 by the endless traction member 19, it is lifted almost vertically and the connection of the connection device 6 is released. Since it is configured,
The coupling device 6 can always be properly released without any mistakes.''-1 The structure is simple and easy to implement.
