Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to a truck conveyance device.

As shown in Japanese Unexamined Patent Publication No. 50-100710, a rope for transporting a cart is provided in an endless manner, a clamping device capable of clamping the rope is provided on the cart, and the cart is fixed to the rope with the clamp device. A device that runs a trolley has been proposed. When the truck is not running, the clamp of the clamp device is released.

The clamp device is located horizontally with respect to the rope, and is configured to clamp the rope from above and below. For this reason, it is necessary to arrange the ropes mainly in a circular shape, and if the route is created at an acute angle, it is difficult to run the trolley.

In addition, a plurality of endless rope routes are provided so that the cart can be moved from the first route to the second route, but the routes are arranged in parallel in the horizontal direction. That is, at the movement locations, the respective routes are provided close to each other in the horizontal direction. On the other hand, the trolley is provided with two clamp devices between the two ropes, so that when one is in the clamped state, the other is in the released state. Therefore, the route (rope) cannot be provided so as to intersect in the vertical direction.

An object of the present invention is to eliminate the above-mentioned drawbacks and to enable more flexible route construction.

The present invention provides a clamping device above the rope, a vertically movable device 1, and
When clamping, the clamping device is moved to the rope side to clamp the rope.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 9.

As shown in Figure 1, each station 1, 2,
Reference numerals 3, 4, 5, 6, and 7 are locations where loads are transferred to, received from, and processed on the trolley 9 that runs on tires 8, which are indicated by two-dot chain lines in FIG. If the carriage 9 is driven by tires 8 as in this embodiment, a floor plate 10 provided on the floor is provided for the passage. If the system uses railway wheels, rails are installed on the floor and used as a path for the bogies.

The floor plate 10 has slits 11 as shown in Figures 2 and 3.
will be provided. Below this slit 11 there is a groove 12 provided under the floor, and a wire rope 13 or wire rope 14 is passed through this groove 12.

The wire rope 13 and the wire rope 14 are each endless, and one wire rope 13 is hung on an endless drive device 15 in the middle, and the other wire rope 14 is hooked on an endless drive device 16 in the middle. For this reason,
The wire rope 13 wound around the endless drive device 15 is transferred from the endless drive device 15 again to the first
It is rolled out in the direction of the X arrow in the figure. Similarly, the wire rope 14 is let out in the direction of the Y arrow by the endless drive device 16. Endless drive device 1
Reference numerals 5 and 16 may be a drum or a sheave around which the wire rope 13 or 14 is partially wound, which is rotated by a motor.

As shown in FIG. 1, the weight of a counterweight 19 or 20 is applied as rope tension to each wire rope 13, 14 through an end pulley 17 or 18. Therefore, each wire rope 13, 14 is driven without loosening. Furthermore, as shown in FIG. 1, each wire rope 13, 14 is bent at a steep angle by each horizontally rotating corner sheave 21 and guided into the groove 12 or out of the groove 12. ing.

As shown in FIG. 1, the path consists of a route A that runs endlessly along the scattered stations 1, 2, 3, and 4, and a route B that runs endlessly around the scattered stations 5, 6, and 7.

In the groove 12 provided along the A route, a wire rope 13 is connected to the corner sheave 21 along the A route.
It is stored by looking into the surrounding area. Similarly, a wire rope 1 is placed in the groove 12 provided along route B.
4 is stored except for the part near the corner sheave 21 along the B route.

Each path of the A route and the B route is curved to follow more stations. Therefore, the wire ropes 13 and 14 accommodated in the grooves 12 provided along the A and B routes are also bent and supported. As shown in FIG. 2, in this support method, a rope receiving sheave 25 is vertically provided at the bottom of the groove 12 directly below the slit 11 in the straight portion, and this rope receiving sheave 25 supports either the wire ropes 13 or 14. do. In addition, in a gently curved part, the deflection sheave 2 is tilted and supported in the groove 12.
6 is provided offset from the center of the slit 11 to the inside of the curve, and one of the wire ropes 13 and 14 is supported on the rope guide surface of this oblique deflection sheave 26. Next, each wire rope 13, 14 is bent at a sharp bending angle by utilizing its flexibility even at a position outside the slit 11, but in this case, it is bent by using a horizontal corner sheave 21.

All stations 1, 2, 3, 4, 5, 6,
It is possible to run a single wire rope along the trolley 7 by taking advantage of the flexibility of the rope, but the number and speed of the trolleys 9 that can be pulled by one wire rope are limited, so if there are a large number of trolleys 9, In this embodiment, two wire ropes 13 and 14 are used. In order to pull the two wire ropes 13 and 14 at high speed, if the passage is grouped so that there are many smooth bends, the orientation of each station 1, 2, 3, 4, 5, 6, and , each A
The route and B route intersect. Therefore, the wire ropes 13 and 14 also cross each other. This intersection is constructed as follows.

That is, as shown in FIG. 9, one of the intersecting wire ropes 14 is guided downward from the rope receiving sheave 25 by the rope guiding sheave 27 so as to be lower than the supporting height of the other wire rope 13, and is guided downward from the rope receiving sheave 25 so as to be lower than the supporting height of the other wire rope 13. It intersects 13 three-dimensionally. After crossing, the wire rope 14 is guided also from under the other rope guide sheave 28 to the top of one rope receiving sheave 25 to its original height.

As shown in Fig. 1, the A route and the B route are connected by bypass passages 29, 30, 31, and 33 through which the wire ropes 13 and 14 do not pass.
The trolley 9 can transfer between the route and the B route using running inertia. Furthermore, the A route itself is provided with a bypass passage 35 along the station 2, and the B route itself is also provided with a bypass passage 36 along the station 6. Any bypass passage is provided between the wire ropes 13 and 14 or between the same wire ropes 13 or 14.

A passage switching device 37 as shown in FIG. 8, for example, is provided at the entrance side end of each bypass passage, that is, at the artificial part. This passage switching device 37 is
A swingable switching plate 38 changes the continuous direction of the slits 11.
It is selected by Further, if the bogie 9 is of a type that runs on railroad wheels, the passageway will be a rail, and the passageway switching device will be a railway point switching device.

The truck 9 equipped with a loading platform is equipped with tires 8 on a bracket 41 that rotates with a pivot pin 40, as shown by the two-dot chain line in FIG. 4, so that the tires 8 can be directed in the traction direction when indexed. This bracket 4

The base frame 43 of the rope clamping device comprises a horizontal projecting surface 44 and a vertical surface 45. The vertical surface 45 of the base frame 13 is bolted to the mounting frame 42 via a horizontal coil spring 46. Therefore, the base frame 43 can be moved in the pulling direction of the truck 9 by the stroke of the coil spring 46. Vertically parallel links 47 and 48 are pin-coupled to the front surface of the vertical surface 45 of the base frame 43 so as to be vertically movable. The swinging end of each link 47, 48 is pin-coupled to a hollow bracket 49.

These clamp arms 58 and 59 extend upward, and the outer surface of the intermediate portion and the clamp frame 5
Compressed horizontal coil springs 64, 65 are provided between the vertical portions of 4 and 4. Therefore, each clamp arm 58, 59 is always acted on in the closing direction by the repulsive force of each coil spring 64, 65. On the upper inner surface of each clamp arm 58, 59, each roller 66, 67, 6 is provided so as to face each other.
8 and 69 are arranged in two rows, upper and lower. At the bottom of the clamp frame 54, as shown in FIG. 5, there is a roller support arm 70 that projects horizontally in the width direction of the passage.

When the collision bumper 77 hits the front truck, the lever 77 rotates backward, so that the wedge 78 is wedged between the lower rollers 68 and 69 attached to the clamp arms 58 and 59.
Therefore, in the event of a collision, each clamp arm 58, 59
As in the case of a manual rope clamp release operating device, the opening operation is performed to cut off the traction force to the trolley 9 and ensure safety.

Wire rope 13,1 to rope clamp device
A rope clamp operating device for causing the action of pinching or separating the rope 4 is also installed on the aisle side. The rope clamp operating device installed on the passage side includes a rope clamp operating device 79 and a rope clamp release device 80. The rope clamp release device 80 is
As shown in FIGS. 1 and 8, each bypass passage 29, 3
0, 31, 33, 35, 36, the entrance positions along each station 1, 3, 4, 5, 7, and any wire rope 1 from inside the groove 12.
3 and 14 are provided at the positions where the wire ropes are pulled out, and furthermore, at the positions along the lower wire rope at the intersection as shown in FIG. 9, and at the positions before guiding the wire rope downward. The rope clamp actuating device 79 is connected to the bypass terminals 29, 30, 3 as shown in FIG.
Positions immediately after the exit end of 1, 33, 35, 36 and groove 1
They are provided at the position where the wire ropes 13, 14 are introduced into the interior of the vehicle 2, and at the position immediately after the lower wire rope is returned to its original height along the lower wire rope at the intersection as shown in FIG.

The rope clamp actuating device 79 and the rope clamp releasing device 80 both include the roller 62 and the roller 6.
3 is installed in the groove 12 so as to face it. The structure of the rope clamp actuating device 79 is as shown in FIGS. 6 and 7. That is, the rope clamp actuator 79
is each rope 62, 63 shown in FIGS. 4 and 5.
A horizontal guide plate 81 that guides the rollers in the horizontal direction and a vertical guide plate 82 that guides the rollers 72 and 73 in the vertical direction.
are provided on the left and right sides respectively. The surface of the horizontal guide plate 81 is formed in the following order from the direction in which the truck 9 approaches. First, there is an opening movement guiding surface 83 whose left and right width narrows as it advances toward the center of the horizontal guide plate 81. Continuing with this opening movement guiding surface 83, there is an opening movement holding surface 84 that is parallel to the left and right sides. There is a closed movement guiding surface 85 whose left and right width gradually increases as it continues to 84. The surface of the vertical guide plate 82 is formed in the following order from the direction in which the truck 9 approaches. Within the range of the opening guide surface 83, there is a receiving slope 86 that is inclined to easily receive each roller 72, 73, and a horizontal guiding surface 87 that is connected to the receiving slope 86.
Within the range of the opening holding surface 84, the guiding surface 87
There is a descending guide surface 88 that is connected to and slopes downward, and a horizontal descending holding surface 89 that is continuous to this descending guiding surface 88, and an extension surface of the descending holding surface 89 is present within the range of the closing movement guiding surface 85. .

The horizontal guide plate 81 and the vertical guide plate 82 are integrated in an L shape or an inverted L shape, as shown by the two-dot chain line in FIG. 5, and are arranged on the left and right sides. As shown in FIG.
0,91, and is further provided with a piston/cylinder device 92 installed obliquely from the side wall of the groove 12 to the horizontal guide plate 81, thereby forming a movable rope clamp actuating device. By causing this piston cylinder device 92 to expand and contract, each guide plate 81, 82 is moved to each roller 62, 63,
By moving the rope from a position in contact with 72 and 73 to a position in which it does not contact, it is possible to select whether or not to apply the action of the rope clamp actuating device 79 to the roller clamp device.

The rope clamp releasing device 80 has the same structure as the rope clamp actuating device 79 except that the vertical guide plate 82 is omitted. This rope clamp release device 80 has a piston similar to the rope clamp actuation device 79.
By attaching the cylinder device 92 and each swing link 90, 91, a movable rope clamp release device can be obtained.

A movable system consisting of each swing link 90, 91 and a piston/cylinder device 92 is located at a position near the entrance of each bypass passage 29, 30, 35, 36, and at an entrance side position along each station 1, 3, 4, 5, 7. Rope clamp release device 8 disposed in each
0 has been adopted. Furthermore, station 7
When the rope clamp releasing device 80 and the rope clamp actuating device 79 are located close to each other, the rope clamp actuating device 79 allows the trolley 9 to be moved to the station 7 by the running inertia of the trolley 9 without having to hang it on the wire rope. It may be possible to arrive. In this case, if the above-mentioned movable method is adopted for the rope clamp actuator 79 and the rope clamp actuator 79 is moved to a non-operating position, the load on each wire rope 13, 14 can be reduced.

The present embodiment configured as described above operates as follows and is used for transportation work.

When the endless drive devices 15 and 16 are started,
Each wire rope 13, 14 is pulled in the direction of the arrow X or Y in FIG. The lower ends of the clamp arms 58 and 59 of the rope clamp device are moved to close by the repulsive force of the coil springs 64 and 65 to grip the wire rope 13. As a result, the trolley 9 travels along the A route while being towed by the wire rope 13.
Similarly, on Route B, the trolley 9 is pulled by a wire rope 14 and runs. After stopping at the station 1 and completing the cargo handling work, the cart 9 is pushed by a worker and moved to the rope clamp actuating device 79 near the station 1. The rope clamp device of the truck 9 grips the wire rope 13 by the action of the rope clamp actuating device 79. This grasping motion is as follows. When the trolley 9 advances to the rope clamp actuating device, each roller 62,
63 is each surface 8 of the horizontal guide plate 81 shown in FIG.
3.Rolling along 84, 85, each roller 72,
73 is each surface 86, 87, 88 of the vertical guide plate 82,
Rolling along 89. For this reason, the opening movement guiding surface 8
3, each roller 62, 63 gradually rolls in the groove 1.
Pushed to the center of 2. Therefore, the lower ends of the clamp arms 58 and 59 begin to open around the clamp rotating shaft 57, and each roller 62,
63, the lower ends of the clamp arms 58, 59 open to the maximum. From the time when the lower ends of the clamp arms 58, 59 are opened to the maximum, the coil spring 52 is compressed by the lowering of the rollers 72, 73 rolling on the lowering guiding surface 88. For this reason, each link 47,
48 rotates and the entire rope clamp device is lowered. When each roller 72, 73 reaches the descending holding surface 89, the lower ends of the clamp arms 58, 59 descend to the height of the wire rope 13. As the trolley 9 further advances, each roller 62, 63 moves toward the closing motion guiding surface 8.
5 and roll the coil springs 64 and 65 back to their original positions.
It returns with the repulsive force of . For this reason, the clamp arm 5
The lower ends of the clamp arms 8 and 59 move closed around the clamp rotating shaft 57, and finally the lower ends of the clamp arms 58 and 59 grip the wire rope 13. As the truck 9 moves further, each roller 62, 63, 72, 73 disengages from each horizontal and vertical guide plate 81, 82 of the rope clamp actuating device 79. Therefore, due to the repulsive force of the coil spring 52, the entire rope clamp device is raised to its original height and held while gripping the wire rope 13.

The cart 9 that has gripped the wire rope 13 in this manner is pulled by the wire rope 13 and travels to the target station. During this traveling, the guide rollers 55 and 56 are guided by the end surface of the floorboard 10, so that the cart 9 smoothly travels along the route A.
Clamp arms 58 and 59 are wire ropes 13
When grasping the wire rope 13, the wire rope 13 is always driven at a constant speed, so an impact is applied to the rope clamp device in the traveling direction. However, this impact is alleviated by the spring action of the horizontal coil spring 46 and does not impact the load on the truck 9.

When the arrival station of the truck 9 is the station 2, the rope clamp release device 80 near the entrance of the bypass passage 35 is representatively shown in FIG. Push it out. Next, as shown in FIG. 8, the switching plate 38 is swung toward the path through which the wire rope 13 passes to open the entrance of the bypass path 35. If this is done, the rope clamp device releases the wire rope 13 when the advancing cart 9 passes the rope clamp release device 80. This release operation is as follows.

That is, the cart 9 pulled by the wire rope 13
When the rope approaches the rope clamp releasing device 80, the rollers 62, 63 of the rope clamping device first roll along the horizontal guide plate 81 of the rope clamp releasing device 80. For this reason, as in the case of the rope clamp actuating device 79, the clamp arms 58, 59
opens when each roller 62, 63 passes the opening holding surface 84. Therefore, the wire ropes 13 of the clamp arms 58, 59 are separated. The released wire rope 13 falls due to its own weight, and the second
It is held by a rope receiving sheave 25 as shown in the figure. Clamp arm 58 with wire rope 13 released,
59 closes the closing guide surface 85 at the time when each roller 62, 63 rolls. Rope clamp release device 8
0 does not have the vertical guide plate 82, there is a difference in height between the wire rope 13 and the lower ends of the clamp arms 58 and 59 at the time of this closing movement. Therefore, the clamp arms 58, 59 do not grip the wire rope 13 again at the time of the closing movement.

In this way, the trolley 9 separated from the wire rope 13 moves forward due to running inertia and reaches the bypass passage 35.
Enter the station and stop at Station 2. When the cargo handling work is finished at this station 2, the cart 9 is manually moved from the bypass path 35 to the path where the wire rope 13 passes. Since there is a rope clamp actuating device 79 at this confluence point, the carriage 9 is again grabbed by the wire rope 13 via the warp clamp device and headed for another destination station.

When the trolley 9 does not need to undergo cargo handling work at the station 2, the rope clamp release device 80 located near the entrance of the bypass passage 35 is compressed by the piston-cylinder device 92, so that each guide plate 81, 82
At the same time, as shown by the dotted line in FIG. 8, the entrance of the bypass passage 35 is closed off with the switching plate 38, as shown by the dotted line in FIG. In this way, the cart 9 is pulled by the wire rope 13 and passes the station 2.

The cart 9 that has passed the station 2 is separated from the wire rope 13 by the rope clamp release device 80 at the portion where the wire rope 13 exits to the end pulley 17 side. Thereafter, the trolley 9 travels due to running inertia and is gripped onto the wire rope 13 again by the next rope clamp actuating device 79.
When approaching the entrance of each bypass passage 33, the trolley 9 is separated from the wire rope 13 by the rope clamp release device 80 near the entrance and travels due to running inertia. When the entrance to the bypass passage 33 is blocked by the passage switching plate 37 at the entrance, the cart 9 passes through the partial passage 34 of route A and heads toward the station 3. By blocking the opposite side with the passage switching plate 37, the cart 9 can move to the B route through the bypass passage 33, and can head from the A route to the station along the B route.

The trolley 9 that has passed through the partial passage 34 of route A is
The wire rope 13 is grasped via the rope clamp device in response to an operation from a rope clamp actuating device 79 arranged at the confluence point with each bypass passage 31 . Therefore, the trolley 9 heads toward the station 3 while being towed by the wire rope 13. When it is necessary to carry out cargo handling work at the station 3, the rope clamp release device 80 near the entrance of the station 3 is pushed out toward the center of the groove 12 by the expansion action of the piston/cylinder device 92. In this way, the cart 9 separates from the wire rope 13 at the entrance of the station 3, stops at the station 3, and receives cargo handling from the station 3. If there is no need to carry out cargo handling work at Station 3,
The rope clamp release device 79 near the entrance of the station 3 is moved backward by the contraction action of the piston/cylinder device 92, and the trolley 9 is allowed to pass through the station 3. The cart 9 that has finished handling cargo at the station 3 is pushed by a worker and passes through a rope clamp actuating device 79 near the station 3. At this point of time, the trolley 9 grabs the wire rope 13 via the rope clamp device and enters a towing state.

After passing the station 3, the carriage 9 reaches the entrance of the bypass passage 30. When the next arrival station of this trolley 9 is on route A, as shown in FIG. Clamp release device 80
is retracted by the contraction action of the piston-cylinder device 92. In this way, the trolley 9 can circulate again along the A route and perform cargo handling work at the stations along the A route. On the other hand, bypass passage 3
If the next arrival station of the cart 9 that has reached the entrance of No. 0 is a station along route B, the switching plate 38 provided at the entrance of the bypass passage 30 is
Swing the bypass passage 3 to the position indicated by the solid line in Fig. 8.
Rope clamp release device 8 installed near the entrance of 0
0 to the center side of the groove 12. In this way, when the trolley 9 passes the rope clamp release device 80, it separates from the wire rope 13 and moves to route B through the bypass passage 30 due to running inertia. When moving to the B route, the trolley 9 is held onto the wire rope 14 by the rope clamp actuating device 79 disposed at the confluence of the bypass passage 30 and the B route and is towed. After that, the process is the same as when traveling on Route A. However, the case of driving at the intersection of route A and route B is different, and will be described later. The other trolleys also operate in the same manner as described above.

When moving from route B to route A, the same process is performed using the bypass passages 29 and 31.

When passing through an intersection between routes A and B, the following procedure can be performed. That is, since the bogie 9 traveling on route A is towed by the wire rope 13, there is no need to perform any operation on the bogie 9 at the intersection, as shown in FIG. However, B
The trolley 9 running on the route is wire rope 1
3. Due to the fact that it is towed by the wire rope 14 below,
The following operation is applied to the trolley 9 side, that is, the rope clamp device. The operation is, before entering the intersection,
An operation in which the wire rope 14 is released from the trolley 9 side using the rope clamp release device 80 shown in FIG. It is.

Wire ropes 13, 1 along each route A and B
4, the curved portion thereof is supported by a deflection sheave 26, and when the bogie 9 passes through this deflection sheave 26, the situation is as follows. That is, the guide roller 5
5, 56 guide the rope clamp device along the end surface of the floorboard 10, so that the clamp arms 58, 5
9 moves through the center of the slit 11. As a result,
As shown by the dotted line in FIG. 3, even if the wire rope 13 or the wire rope 14 is held, the clamp arms 58 and 59 do not hit the deflection sheave 26, and the truck 9 runs smoothly.

In this embodiment, each wire rope 13, 14 continues to be driven at a constant speed regardless of whether the trolley 9 is running or stopping. Therefore, even if the preceding cart 9 is stopped, the following cart 9 continues to run. If the preceding bogie 9 is stopped at station 3 on route A, the below-mentioned bogie 9 traveling on route A will stop at station 4 only on route A.
I can't go to In such a case, the following truck 9 is moved from the bypass passage 33 to the B route, and then again from the bypass passage 29 to the A route, thereby allowing it to go to the station 4. In addition, when there is a lot of transportation work on the B route, the empty trolleys on the A route are moved to the B route via the bypass passages 30 and 33 and used for the transportation work. Similarly, move the empty truck on route B to A.
It can also be transferred into the route via the bypass passages 29 and 31 and used for transportation work within the A route.

The rope clamp device provided on the trolley 9 has an automatic rope clamp release operation device that automatically releases the wire rope in the event of a collision. When hit by the collision bumper plate 77 integrated with the clamping device, the V-shaped lever 76 rotates to the right and the wedge 78
is inserted between the rollers 68 and 69 attached to the clamp arms 58 and 59. Therefore, the lower ends of the clamp arms 58, 59 open and release the wire rope 13 or wire rope 14. Therefore, not only is it possible to prevent more impact from being applied to each of the carts 9 involved in the collision, but also to the other carts 9 being towed by the wire rope 13 or wire rope 14 or each of these wire ropes 13 and 14. I can't tell you. In this way, even if a collision occurs, the wire ropes 13 and 14 continue to be driven and pull the other truck 9. Therefore, transportation work does not stop. If a collision occurs and the truck 9 is damaged, the rail clamp device of the truck 9 is pulled out of the slit 11 using the vertical swinging motion of each link 47, 48, and the truck 9 is removed from the passage. Manually tow it to a place where it will not interfere with the movement of other trolleys. During this manual towing, it is convenient to use the pull bar 74.

Now, as described above, the clamp device is installed above the ropes 13, 14, is biased upward by the spring 52, and is movable up and down. On the other hand, a clamp actuating device 79 for clamping the clamp device to the ropes 13 and 14 includes a horizontal guide plate 81 for opening the clamp portion so as to clamp the rope, and a clamp actuating device 79 for clamping the rope with the clamp portion open.
It consists of a vertical guide plate 82 that lowers the clamping device from above to the rope position. For this reason, the clamping device is above the rope when not clamping, and even if the cart moves in the radial direction of the rope, the clamping device will not hit the rope.

Furthermore, a carriage passage is provided in parallel to the corner sheave at an acute angle portion of the corner sheave 21, etc., and a clamp actuating device and a clamp releasing device are provided before and after this. In addition, the intersection of route A and route B,
Moreover, clamp release and clamp actuation devices are provided before and after the bypass passages 29, 30, 31, 33, 35, and 36 between the A route and the B route.
For this reason, in such parts the clamping device disengages from the rope and passes over the rope.
In the next part, it is lowered and clamped to the rope.

Therefore, the acute angle part does not hit a corner sheave or the like, and the ropes can be crossed or moved between ropes.

As described above, according to the present invention, it is not possible to adopt an acute route, to move from one route to another, or to cross the ropes of one route and the other route vertically. This allows for more flexible routes.
