DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION According to the claimed invention is to transport carriage set Bei Seki <br/> for performing classification operation or transport task cargo, details efficiently transported sorting or large amounts of freight it is relates cargo transport vehicle set Bei capable or.

[0002]

2. Description of the Related Art Conventionally, conveyor type transport equipment and transport equipment using a forklift have been widely used for sorting and transporting cargo, and have been used to sort and transport a large amount of cargo. . There is an air cargo (cargo / baggage) transport facility at an airport as a facility that uses this type of transport facility. Hereinafter, this air cargo transport facility will be described as an example.

In recent years, air cargo has been heavily used to export products and parts produced at production sites in other countries to other countries, and to quickly export high-quality fresh fish and the like from a producing country to other countries. . Therefore, in order to cope with such a rapid increase in the handling volume of air cargo, there is a need to transport a large amount of cargo at a high speed by increasing the size of airport facilities or increasing the transport distance.

[0004] On the other hand, transport equipment for sorting and transporting such air cargo in a three-dimensional warehouse at the airport and loading it into containers is provided with extremely high transport services such as high reliability and high speed. Because standards are required,
It is difficult to process the above-mentioned conventional transport equipment.

[0005] Therefore, in some cases, a cargo transport facility using a plurality of self-propelled transport vehicles is introduced so that a large amount of cargo can be transported. There are two types of cargo transport equipment: a suspension type in which a transport vehicle travels along rails provided on the top, and a floor-standing type in which a transport vehicle travels along rails provided on the floor. The traveling of the type carrier is controlled by a ground control system controlled from the ground or an on-board control system controlled from the vehicle.

[0006] As a prior art for a floor-mounted transport trolley, the invention described in Japanese Patent Application Laid-Open No. Sho 60-193756 describes an electric trolley in an unmanned transport system that travels along one rail. In the invention described in JP-A-193775, an unmanned transport type electric bogie that travels along two rails is described.

[0007]

However, in the case of using the above-mentioned suspension type transport cart, the transport cart may swing due to the uneven load of the cargo because the carrier is supported only on the upper portion of the cart. Therefore, a large occupied space is required in order to avoid interference with other equipment due to the swing of the transport vehicle.
In addition, since the load of the carrier and the cargo is supported only by the upper rails, the rails and their supporting bases become large, and a large facility cost is required. Furthermore, it is necessary to drastically reduce the transport speed in order to minimize the inclination due to centrifugal force when traveling on a curve, etc., and it is difficult to configure a transport facility that needs to transport a large amount of cargo at high speed. Become.

[0008] Further, in the case of using the floor-mounted transfer cart,
In order to stabilize the carriage, two or more rails are required, so that the area occupied by the rails becomes large. In addition, when the rails are branched and joined to switch the course of the carriage, two or more rails need to be switched. Therefore, the distance of the switching operation becomes longer, the operation time becomes longer, and the cycle time of the system becomes longer. In addition, if these distances between rails are not managed, smooth switching and running cannot be performed, so that a great deal of labor and cost are required for rail management. Incidentally, the above-mentioned JP-A-60-19
In the invention described in Japanese Patent No. 3756, the carriage is supported by one rail, and therefore, lacks stability when the load is unbalanced due to the uneven load of the cargo. Also, in the case of these floor-mounted transport vehicles, the transport speed must be greatly reduced in order to reduce the inclination due to centrifugal force when traveling on a curve, etc., and transport equipment that needs to transport a large amount of cargo at high speed. Is difficult to configure.

On the other hand, in such a ground control method of a tracked transport vehicle, a blockage control for constantly grasping the position of the transportable vehicle is generally employed. Has to be limited to one, the number of transport vehicles increases, the number of blocks increases, which complicates the control by the ground controller, resulting in an increase in the cost and reliability of the control device. I will.

In the on-vehicle control system of the tracked carrier, it is necessary to install an operation control device on the ground in order to perform the merging / branching. It is necessary to exchange the current position of the transport vehicle and the control information for branching to and from the transport vehicle on the ground side by communication with the on-board controller of the transport vehicle at all times or at regular intervals. It becomes necessary, which leads to an increase in cost and a decrease in reliability due to the complexity of the equipment.

[0011]

Therefore, in order to solve the above-mentioned problems, the cargo transport trolley facility of the invention according to the present application is provided with rails above and below the cargo transport trolley, and along the lower rail below the transport trolley. In addition to providing traveling means, the transporting vehicle is provided above the transporting vehicle, and upper supporting means for supporting the upper portion of the transporting vehicle along the upper rail is provided to vertically support the transporting vehicle. By vertically supporting the transport vehicle in this way, it is possible to easily prevent the deflection and inclination due to the eccentric load of the cargo acting on the transport vehicle with a simple structure, and also to make the switching operation distance of the rail junction short and easy. Therefore, a large amount of cargo can be transported at high speed.

[0012]

Further, two containers S for loading a plurality of cargoes are placed on the bottom frame 1 in front and behind, and a chain conveyor 5 for lateral movement for loading and unloading is provided below the containers S. Have been. By driving the chain conveyor 5, the container S loaded with cargo can be unloaded in the lateral direction. Reference numeral 5a denotes a stopper for moving the container S to the center of the bottom frame 1 by moving sideways together with the chain conveyor 5, and reference numeral 5b denotes a driving device of the chain conveyor 5.

[0017] The cargo transport trolley equipment T is provided with one rail on each of the upper and lower sides for the transport trolley t to travel. A traveling means V that travels along the lower rail 12 is provided below the transport vehicle t, and an upper support means W that supports the upper portion of the transport vehicle t along the upper rail 13 is provided above the transport vehicle t. ing. The traveling means V and the upper support means W constitute a monorail type cargo transporting trolley facility T in which the transporting trolley t is supported up and down. Since the upper rail 13 is for preventing tilting at the upper part of the transporting vehicle t, it may be a lightweight member capable of withstanding only a lateral load caused by an eccentric load or the like. Since it is prevented from tilting, a member that can withstand only a vertical load may be used.
Since the load acting on the transport vehicle t is distributed at 13, the weight of the rails 12, 13 can be reduced.

In this embodiment, the traveling means V is provided with a traveling wheel 7 having a motor 6 as a driving machine and traveling along the upper surface of the lower rail 12 and sliding along both side surfaces of the lower rail 12. It comprises a guide roller 8 and a support shaft 9 serving as a support means for supporting the guide roller 8 and the traveling wheel 7 integrally and rotatably about a vertical axis. Therefore,
When the motor 6 is driven, the traveling wheel 7 travels on the lower rail 12, and at this time, the traveling wheel 7 is supported by the integrated guide roller 8 so as not to come off from the lower rail 12 so as to follow the lower rail 12. The vehicle can travel while rotating around the axis 9. Reference numeral 18 denotes a support for the lower rail 12.

A guide roller 10 serving as an upper support means W for supporting an upper portion of the transport vehicle t is provided on an upper portion of the upper support frame 2, and in this embodiment, a vertical axis which substantially coincides with the traveling wheel 7 is provided. A guide roller 10 is provided on the upper rail 13 so as to sandwich the upper rail 13 from right and left. By providing the traveling wheels 7 and the guide rollers 11 in such a manner that the vertical axes thereof are substantially coincident with each other, it is possible to keep the bottom frame 1 substantially horizontal without inclining the bottom frame 1 even when the transport vehicle t is traveling on a curve.
The upper support means W may be provided at one location on either side of the front or rear, or may have another configuration.

Further, power for driving the motor 6 is supplied from a power supply 14 provided along the upper rail 13, and a current collector 11 provided on the upper part of the transport vehicle t is supplied by the power supply 11. By sliding along 14, the current collector 11 is supplied with power from the power supply 14. By providing the current collector 11 on the side of the guide roller 10 serving as the upper support means, the distance between the current collector 11 and the upper rail 13 is always kept constant.

The on-board controller 4 provided at the front of the bottom frame 1 is configured to detect its own traveling distance from the number of revolutions of the motor 6 and to record information on the transfer station and the like. ing.

On the other hand, the rail 1 on which the transport vehicle t travels
The main lines 2 and 13 are provided with main lines 12a and 13a for traveling on trucks and drop-in lines 12b and 13b for loading and unloading cargo, and a branch portion A from the main lines 12a and 13a to the drop-in lines 12b and 13b (see FIG. And a junction B to the main line, a switch C is provided. This switching machine C is a main line 1
2a, 13a side lower rail 12c and upper rail 13c
And the lower rail 12d and the upper rail 13d on the side of the drop lines 12b and 13b are integrally switched. These rails 12c, 12d, 13c and 13d on the slide frame 16 provided in the frame member 15 are switched. Switching is performed by expanding and contracting the cylinder 17 serving as a means. The lower slide frame 16a and the upper slide frame 16b in FIG. 1 are connected by a member (not shown) so as to slide integrally.

According to the cargo transport trolley equipment T configured as described above, the driving wheel 6 travels on the lower rail 12 by driving the motor 6 so that the guide roller 8 is along the lower rail 12. Since the guide roller 10 of the upper support frame 3 travels along the upper rail 13, the transport vehicle t travels in a stable state. In addition, in the branching section A (FIG. 5) and the merging section B, the lower rail 12b and the upper rail 13b on the service line side are switched so as to be continuous with the lower rail 12a and the upper rail 13a on the main line side.
At the time of branching to 2b, 13b or merging to the main lines 12a, 13a, the upper and lower guide rollers 8, 10 can smoothly travel with the transport cart t kept substantially horizontal. Therefore, even if an uneven load of uneven cargo or a centrifugal force such as when traveling on a curve is applied to the transport trolley t, a large amount of cargo can always be transported in a stable state at high speed.

Next, a control device of such a cargo transport trolley facility T will be described below with reference to FIGS. FIG.

FIG. 3 is a schematic diagram showing a passing state of a main line side transport vehicle, and FIG. 2 (b) is a schematic diagram showing a merging state of a drop line side transport vehicle. FIGS. 5A and 5B are explanatory diagrams for controlling a transport carriage that transports a cargo from a transport source station to a destination station by the control device. FIG. 5A is a schematic diagram illustrating a state at the transport source station, and FIG. Schematic diagram showing the state, (c)
FIG. 3 is a schematic diagram showing a state in a transfer destination station. FIG. 6 is a schematic diagram for explaining automatic speed control of the transport vehicle, and FIG. 7 is a schematic diagram for explaining unitization of the ground controller. In the following description, the transport vehicle t in the above embodiment will be described as an example, and only the lower rail 12 will be illustrated and described.

First, the basic configuration of the control device will be described.
The control device of the invention according to this application detects the departure or arrival of the transport vehicle t by the ground controller 20 provided on the ground side or controls the rail switching at the branching section A and the merging section B, and is provided on the transport vehicle side. It has functions such as detection of the traveling distance of the traveling wheels 7 by the on-board controller 4, control of the rotation speed of the motor 6, and distance control for keeping the distance to the front transporting vehicle t at a predetermined distance or more.

The main rail 12a for always moving the carriage t only in one direction is provided in a circular shape.
At a predetermined position on the main line, a drop-in line 12b for loading and unloading cargo is branched off at a branching portion A. The exit line merging portion B of the drop line 12b is formed so as to merge with the main line 12a. This drop line 1
Also in 2b, all the transport vehicles t travel in only one direction. In addition, control is performed such that the transport vehicle t traveling on the side of the main line 12a travels preferentially.

Next, the control in the junction B will be described with reference to the schematic diagram of FIG. 4 (a) when passing through the main carriage, and the schematic diagram of FIG. 4 (b) when starting the drop-side carriage. These figures, when detecting that there is conveyance carriage t ₁ to get away from the lead-in wire 12b side on the main line 12a on the ground controller 20, the conveyance carriage t ₂ and drop cable 12 on the main line 12a
indicates the priority order of the conveyance carriage t ₁ on b, FIGS. 4 (a)
As shown in the figure, when the ground controller 20 detects that the transport vehicle t is traveling in a predetermined range (not shown) on the main line 12a, the main line 12a outputs a signal indicating that the vehicle can enter by a traffic light 19a. At the junction B, the rail 12c is connected to the main line side. At this time, since the signal 19b of the drop-in line 12b outputs a signal indicating that entry is impossible, the drop-in line 12b
Transport truck t ₁ of the above is stopped.

Then, as shown in FIG.
When the ground controller 20 detects that the transport vehicle t is not traveling in the predetermined range on the main line 12a, the main
9a, a signal indicating that entry is impossible is issued, and the rail 12d of the junction B is switched so that the service line side is continuous. At this time, so that the outgoing to incoming line 12b side of the signaler 12b is determined to allow travel conveyance carriage t ₁ on the incoming line 12b so issues a signal entering accepted on the main line 12a. The signaler 19a, as a method of transport vehicle t _1, t ₂ entry whether the transport carriage is detected by 19b, ringer 19a,
A different detection bar (not shown) is protruded toward the rail 12a according to the signal of 19b, and the protruding detection bar is detected by a detector (not shown) provided on the carriages t ₁ and t _2. Can be achieved. Main line 1
As means for judging that the transport vehicle t is not traveling in the predetermined range on 2a, switches and the like are provided on the entrance side and the exit side of the predetermined range, and the entrance side switch and the exit side switch are used. It is easily possible if the number of passes is detected. The predetermined range may be determined according to the number of traveling vehicles t and the traveling speed. Further, the signal 19
The means for detecting the entry permission / non-permission signals of a and 19b on the side of the transport vehicle t may have another configuration.

[0029] Thus, through the merging section B conveyance carriage t ₂ which is traveling in the main line 12a side is preferentially main 12a
Conveying carriage t ₁ from the drop cable 12b side when it is detected that the transport vehicle t to a predetermined range of the side is not running is to exit onto the main line 12a.

Next, based on the schematic diagrams of FIGS. 5A to 5C, the transfer from the transfer source station 21 to the transfer destination station 2 is performed.
The control of the transport vehicle t that transports the cargo up to 2 will be described. In this example, a case in which a cargo is transported from the transport source station 21 to the second transport destination station 22b will be described, and the same components as those in the above embodiment will be described with the same reference numerals.

FIG. 3A is a schematic diagram showing a state at the transfer source station 21, showing a state in which predetermined information is recorded on the transfer carriage t by a recorder 23 on the ground side provided at the transfer source station 21. The information recorded by the recorder 23 is a readable and writable identification card 24 (this identification card 24 is referred to as an “IDENTIFICATION CARD”), which is an identification means connected to the on-board controller 4 of the transport vehicle t.
Hereinafter, it is simply referred to as “ID card”). As the ID card 24, for example, a magnetic card is used, and the information to be recorded includes its own transport vehicle number and the destination station 22 for unloading the container S loaded with cargo.
And so on.

In the schematic diagram (b) showing the state during the transfer, the ID is read by the reader 25 on the ground side provided in front of the branch section A of the first transfer destination station 22a.
The information on the card 24 is read. According to the information read by the reader 25, the transport trolley t is moved to the container S (freight).
When it is detected that the transfer destination station 22 which is to transport the
Is not switched, and the rail 12c on the side of the main line 12a is made continuous so as to pass through the transport carriage t.

Next, in the schematic diagram (c) showing the state at the destination station, the second destination station 22b
The information on the ID card 24 is read by a ground-side reader 25 provided in front of the branching section A. According to the information read by the reader 25, the container S of the transport vehicle t
2nd destination station 2 to transport (freight)
When it is detected that 2b is on the drop line 12b of the branch A, the branch A is switched to make the rail 12d on the drop line continuous with the main line 12a. Therefore, the transport trolley t is drawn into the drop line 12b along the rails 12a and 12d,
Detector 26 provided at second transfer destination station 22b
To stop at a predetermined position.

When the transport vehicle t is running, the on-board controller 4 on the transport vehicle t side transmits the transport source station 21 shown in FIG.
Since the travel distance after departure and the destination station 22 are recognized, it is determined by its own controller that the branch A of the target destination station 22 is approaching as in the state (c) above. The control is performed such that the speed is detected at 4 and the speed is reduced when approaching the branch A. In the states (b) and (c),
It is controlled so that the distance from the transport vehicle t traveling in front is maintained at a certain value or more.
(See FIG. 3) to prevent contact by controlling the distance from the transporting vehicle t running forward to be less than a predetermined distance.

On the other hand, the ground controller 20 determines whether or not the transport truck t is loaded with a container S (freight) to be unloaded to the destination station 22 before each branching section A. For example, when the transfer truck t arrives at a predetermined position of the transfer destination station 22 by switching the branching section A, the transfer truck t is stopped and the container S is controlled to be lowered. Therefore, the ground controller 20 controls the respective transport vehicles t at the start point and the arrival point, controls the path of each transport vehicle t at each branching section A, and the junction B
The control of the transport vehicles t by the ground controller 20 is a simple control even if many transport vehicles t are run on the same main line 12a because the position control of each transport vehicle t is not performed only by performing the control in the above. In addition, the control system is simplified, and a plurality of transport vehicles t can be controlled by a simple control device.

The transport trolley t having the container S lowered to a predetermined position of the transport destination station 22 in this way joins the main line 12a under the control of the junction B described above. It should be noted that a new container S is loaded at this destination station 22 and another destination station 22 is loaded.
In the case of transporting to the destination station, information of a new destination station or the like is written by a recorder (not shown) provided at the destination station 22, and the control by the ground controller 20 and the on-board controller 4 as described above. Conveyed by

In the above-described embodiment, the switching operation of the branching section A and the merging section B by the ground controller 20 has been described. Next, a schematic diagram for explaining the automatic speed control of the transport vehicle shown in FIG. Based on the above, an example of a method of controlling the speed of the transport vehicle t by the on-board controller 4 will be described.

This embodiment shows a case in which a transport vehicle t traveling on a main line 12a provided in a loop shape automatically decelerates or accelerates when traveling on a branch A or a curve. The on-board controller 4 on the t side automatically reads the identification means 27 provided on the ground and controls the speed. In this example, when the on-board controller 4 reads the identification means 27 provided in front of the branch A of the drop-in line 12b, the vehicle decelerates. When the identification means 27 reads that the vehicle has passed the junction B, it accelerates. When the identification means 27 is read, the speed is automatically controlled to be reduced, and when the identification means 27 reads that the vehicle has passed the curve, the speed is automatically controlled. Therefore, if the identification means 27 is installed at a predetermined position on the ground, the transport vehicle t automatically reads the information and controls the speed, so that the most efficient traveling control can be performed. Note that the speed can be easily controlled by using a known technique based on a voltage change or a known technique based on the position of a contact sensor as the identification means read by the transport vehicle t.

Also in this case, similar to the above embodiment, the branch portion A
When the vehicle travels from the destination station 22 to the target destination station 22, the on-board controller 4 of the transport trolley t reads the information of the identification means 27 provided at the target destination station 22 and can automatically stop. . Note that the above-described ID card 24 may be used as the identification means 27.

Further, as described above, the ground controller 20 in the invention according to the present application determines whether or not the transport cart t loaded with the container S (freight) to be unloaded to the destination station 22 at each branch A. The control system is simplified by switching the branching section A, stopping the transport carriage t at a predetermined position of the transport destination station 22, and unloading the container S.
As shown in the schematic diagram for explaining the unitization of the ground controller in the transport vehicle control device shown in FIG. 3, by unitizing the branching portion A, the junction B, and the destination station 22 of the service line 12b in a certain predetermined range, Ground controller 20
Can be further simplified to form a simple control device. The control device can be simplified in this way because control by the ground controller 20 and control by the on-board controller 4 are separated.

Incidentally, this unitization may be appropriately set according to the number of transfer destination stations 22, the size of the entire equipment, and the like.

As described above, according to the invention of the present application, the necessity of the ground operation control device for managing the transport trolley and the management of the entire system for performing complicated communication between the ground and the vehicle become unnecessary. The control system of the signaling device by the ground controller focusing only on each branching junction, and the on-board controller of the transport vehicle t autonomously judges whether or not to enter by identifying the signaling device, the control system of the branching junction is realized. It can be simplified.

Therefore, according to the invention of this application, even if the number of the transport vehicles t increases, the transport vehicles t
Performs traveling control by the on-board controller 4 provided on its own, and the ground controller 20 performs only control at each branching section A and the merging section B. Therefore, the configuration as a control device is not limited to the number of bogies. And the number of bogies can be increased or decreased freely.

[0044]

According to the freight carrier equipment, the carrier is supported up and down, and the traveling means and the upper supporting means are connected to the vertical axis.
Are provided so as to substantially coincide with each other, so that it is possible to convey the cargo at a high speed by preventing the swaying and tilting of the carrier cart, and furthermore, the area occupied by the rails is reduced and the switching operation distance is shortened, so that the equipment is reduced in size. As a result, it is possible to carry out high-speed, large-volume freight transportation with reduced equipment costs and greatly reduced transportation time.

Further, the traveling means of the carriage is constituted by traveling wheels provided with a driving device, guide rollers along the lower rail, and supporting means for supporting these rotatably about a vertical axis.
Therefore , it is possible to easily form a configuration in which the transport trolley travels along the rail, and the current collector is provided above the transport trolley to supply the driving power from the upper rail .
Ri, it becomes possible to easily supply power to the platform car.
