Description

  The present invention relates to a vehicle system including a vehicle that travels with an elastic force stored in an elastic body and a station where the vehicle stops.

  Conventionally, in a production site such as an automobile factory, for example, a battery is mounted as a vehicle for transporting parts (workpieces) such as an engine and a gear box to each work station, and a driving motor is driven to rotate by electric power from the battery. Thus, an automated guided vehicle (AGV) that drives the drive wheels to travel is used. In this type of transport vehicle, since a heavy object such as an engine component is transported, a sufficient output is required for the traveling motor. Therefore, there is a concern about an increase in equipment cost and power consumption due to an increase in the size of the motor and the accompanying increase in the size of the vehicle.

Patent Document 1 describes a configuration in which an electric or hydraulic drive system is not provided as a transport vehicle for transporting parts (workpieces) such as an automatic transmission. In this transport vehicle, the rack and pinion mechanism is driven by the weight of the work to be transported to generate a forward driving force of the wheel, and the weight of the work is stored in a coil spring (elastic body) provided on the base. Then, the rack and pinion mechanism can be driven in the reverse direction by the repulsive force of the coil spring when the workpiece is removed from the pedestal, and the reverse drive force of the vehicle can be obtained.
Japanese Patent Application Laid-Open No. 2004-331052

In this case, since the height of the pedestal is changed based on the movement in the transport vehicle described in Patent Document 1, it is difficult to apply to a production line for assembling parts mounted on the pedestal. It is. On the other hand, in order to store the elastic force in the elastic body without changing the height of the pedestal, it is necessary to mount a power source for storage, and there is a problem that the weight of the vehicle increases accordingly.
In addition, for example, when an electric motor is mounted as a power source for storage, when the vehicle is stopped at the station, an external power source provided in the station is connected to the electric motor. A configuration for driving an electric motor is assumed. However, in a work station that is wet with water, there is a problem that it is difficult to connect to an external power source.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a vehicle system capable of reducing the weight of a vehicle and storing an elastic force in an elastic body easily even in a workplace wet with water. To do.

  In order to solve the above-described problems, the present invention provides an elastic body that is connected to a drive wheel of a vehicle body and can store power by converting power into elastic force, and can output the stored elastic force to the drive wheel as power. A vehicle having an energy storage mechanism, and a station where the vehicle stops. The station is connected to the energy storage mechanism of the vehicle when the vehicle stops at the station, and the energy storage mechanism It is characterized by comprising a power source for stockpiling that stores power in the elastic body.

  According to this configuration, the station is provided with a power source for storage that is connected to the energy storage mechanism of the vehicle when the vehicle stops at the station and stores power in the elastic body of the energy storage mechanism. It is not necessary to provide a power source for stockpiling in the vehicle, and the vehicle can be reduced in weight and reduced in size. Furthermore, it is only necessary to supply power to the energy storage mechanism of the vehicle from the storage power source of the station, and it is possible to easily store the elastic force in the elastic body even in a workplace wet with water. In addition, since the storage drive source is provided not at each vehicle but at the work station, when the number of work stations is smaller than the number of vehicles, the number of storage drive sources to be arranged is reduced, and the system configuration is reduced. Is possible.

  In this configuration, the vehicle includes a clutch mechanism that switches between output of power from the elastic body of the energy storage mechanism to the drive wheel of the vehicle and regeneration of power from the drive wheel to the elastic body. When moving the vehicle, the vehicle travels with the power stored in the energy storage mechanism, and the clutch mechanism is switched to the regenerative side during the travel so that power can be regenerated from the drive wheel to the elastic body while traveling. May be.

  According to this configuration, since the clutch mechanism that switches the output of power from the elastic body of the energy storage mechanism to the drive wheel of the vehicle main body and the regeneration of power from the drive wheel to the elastic body is provided, by switching the clutch mechanism, The power of the driving wheel during traveling can be regenerated (stocked) as an elastic force in the elastic body of the energy stockpiling mechanism. For this reason, in the station which stopped, the power source for stockpiling should be driven and the elastic force which is insufficient with the regenerated part should just be replenished to the elastic body of an energy stockpiling mechanism. Therefore, power for storing elastic force in the elastic body can be reduced, energy consumption for driving the power source for storage can be reduced, and energy saving can be achieved.

  Further, in this configuration, the vehicle includes a main drive wheel that drives the vehicle main body and a traveling motor that drives the main drive wheel, and the power stored in the elastic body of the energy storage mechanism is At the start, the driving force of the driving motor is assisted, and the clutch mechanism is switched to the regeneration side near the end point of the inter-station distance to regenerate power from the driving wheels to the elastic body while traveling. You may comprise.

  According to this configuration, since the power stored in the elastic body of the energy storage mechanism assists the driving force of the traveling drive source when the vehicle starts, it is possible to use a low-power and small-sized traveling drive source. This makes it possible to reduce the weight and energy of the vehicle. Furthermore, near the end point of the inter-station distance, the clutch mechanism is switched to the regeneration side so that power can be regenerated from the drive wheels to the elastic body while traveling. Thus, it is sufficient to replenish the elastic body of the energy storage mechanism with an elastic force that is insufficient for the regenerated portion. Therefore, power for storing elastic force in the elastic body can be reduced, energy consumption for driving the power source for storage can be reduced, and energy saving can be achieved.

According to the present invention, the station is provided with a power source for storage that is connected to the energy storage mechanism of the vehicle when the vehicle stops at the station and stores power in the elastic body of the energy storage mechanism. It is not necessary to provide a power source for stockpiling in the vehicle, and the vehicle can be reduced in weight and reduced in size. Furthermore, it is only necessary to supply power to the energy storage mechanism of the vehicle from the storage power source of the station, and it is possible to easily store the elastic force in the elastic body even in a workplace wet with water. In addition, since the storage drive source is provided not at each vehicle but at the work station, when the number of work stations is smaller than the number of vehicles, the number of storage drive sources to be arranged is reduced, and the system configuration is reduced. Is possible.
Further, according to the present invention, since the clutch mechanism for switching the output of power from the elastic body of the energy storage mechanism to the drive wheel of the vehicle body and the regeneration of power from the drive wheel to the elastic body is provided, the switching of the clutch mechanism is performed. Thus, the power of the driving wheel during traveling can be regenerated (stocked) as an elastic force in the elastic body of the energy stocking mechanism. For this reason, in the station which stopped, the power source for stockpiling should be driven and the elastic force which is insufficient with the regenerated part should just be replenished to the elastic body of an energy stockpiling mechanism. Accordingly, the power for storing the elastic force in the elastic body can be reduced, the energy consumption for driving the power source for storage can be reduced, and energy saving can be achieved.
In addition, according to the present invention, the power stored in the elastic body of the energy storage mechanism assists the driving force of the travel drive source at the start of the vehicle. This makes it possible to reduce the weight and energy of the vehicle. Furthermore, near the end point of the inter-station distance, the clutch mechanism is switched to the regeneration side so that power can be regenerated from the drive wheels to the elastic body while traveling. Thus, it is sufficient to replenish the elastic body of the energy storage mechanism with an elastic force that is insufficient for the regenerated portion. Accordingly, the power for storing the elastic force in the elastic body can be reduced, the energy consumption for driving the power source for storage can be reduced, and energy saving can be achieved.

For example, a work such as an engine or a gear box of an automobile is used. An AGV that loads W onto the mounting table 16 and transports it to a desired position in the factory. In the present embodiment, the transport vehicle 10 will be described as an example of the electric vehicle. However, the present invention is applicable to any vehicle that travels electrically, such as a passenger car, an electric cart, and a train.

  Such a transport vehicle 10 is mainly driven by the main power unit 14 that is driven during normal travel, and auxiliary power that is driven when the transport vehicle 10 starts from a stopped state and assists the travel by the main power unit 14.

A plate 44 is bridged in the vehicle width direction of the body frame 24, and an input shaft 27, a main shaft (rotary shaft) 41 and an intermediate shaft 42 are supported on the plate 44 so as to be substantially parallel and rotatable. Has been. A drive shaft 43 (FIG. 3) of the auxiliary drive wheel 38 is provided below the intermediate shaft 42, and the drive shaft 43 is rotatably supported by the vehicle body frame 24.
The input shaft 27 is pivotally supported on the plate 44 by a pair of bearing portions 33, 33, and on one of the shaft end portions (right side of the vehicle body in the present embodiment) when the transport vehicle 10 stops at the station. A coupling 25 connected to a hoisting motor 36 installed at this station is provided. The coupling 25 is located in the vehicle body frame 24 so as not to protrude from the vehicle body frame 24, and is formed in the body 23 and is opened through an opening (not shown) and is fixed to the motor shaft 36a of the winding motor 36. Engage with the ring 21.
As described above, in this embodiment, each work station 102a includes the winding motor 36 that is connected to the energy storage mechanism 34 of the transport vehicle 10 and stores power in the mainspring 32 of the energy storage mechanism 34. 10 does not need to be provided with a winding motor 36 for writing the mainspring 32, and weight reduction and downsizing of the transport vehicle 10 can be realized. Further, it is only necessary to supply a rotational driving force from the winding motor 36 of each work station 102a to 102c to the energy storage mechanism 34 of the transport vehicle 10 via the input shaft 27. The elastic force can be stored in 32.

  In the present embodiment, for example, the hoisting motor 36 installed in the work station 102a is placed on a carriage 90 in which the motor shaft 36a and the input shaft 27 have substantially the same height. By moving the conveyance vehicle 10 in the vehicle width direction, the motor side coupling 21 of the winding motor 36 and the coupling 25 of the input shaft 27 are engaged or disengaged. The input shaft 27 is provided with a brake 35 and a first sprocket 37. The brake 35 is, for example, an electromagnetic brake, and permits or prohibits the rotation of the input shaft 27 under the control of the control unit 22.

  The main shaft 41 is divided into a first shaft (first rotating shaft) 41a and a second shaft (second rotating shaft) 41b. The first shaft 41a and the second shaft 41b are respectively a bearing portion 46, 47 is pivotally supported on the plate 44. A bottomed cylindrical casing 45 is fixed to the shaft end of the second shaft 41b. In the casing 45, the shaft end of the first shaft 41a extends and a spiral spring 32 is housed. Has been. One end of the mainspring spring 32 is fixed to the inner wall surface 45a of the casing 45, and the other end of the mainspring spring 32 is fixed to the outer periphery of the shaft end portion of the first shaft 41a. Accordingly, the mainspring spring 32 is wound around the first shaft 41a based on the rotation of the first shaft 41a and the second shaft 41b. In the present embodiment, the inner wall surface 45a of the casing 45 functions as a parallel portion that extends parallel to the axial end portion of the first shaft 41a.

A second sprocket 48 connected to the first sprocket 37 of the input shaft 27 via a chain 39 is provided at the end of the shaft opposite to the casing 45 of the second shaft 41b. A first one-way clutch 49 is provided between the sprocket 48 and the second shaft 41b.
The first one-way clutch 49 is engaged with the second shaft 41b when the second sprocket 48 rotates in the forward rotation direction (direction rotated by the hoisting motor 36), and the second sprocket 48 rotates in the reverse rotation direction. In this case, a mechanical clutch that slips when the above-described engagement is released.

  Further, the second shaft 41b includes a third sprocket 50 disposed between the second sprocket 48 and the casing 45, and an input clutch 51 for switching the third sprocket 50 and the second shaft 41b so as to be able to contact and separate. Is arranged. The input clutch 51 is, for example, an electromagnetic clutch. When the input clutch 51 is engaged under the control of the control unit 22, the third sprocket 50 and the second shaft 41 b are engaged and the third clutch 41 is engaged. The sprocket 50 rotates with the second shaft 41b. On the other hand, when the engagement of the input clutch 51 is released, the engagement between the third sprocket 50 and the second shaft 41b is released, and the third sprocket 50 slips with respect to the second shaft 41b.

On the other hand, the first shaft 41a includes a fourth sprocket 52, an output clutch 53 for switching the fourth sprocket 52 and the first shaft 41a in a freely detachable manner, between the pair of bearing portions 46, 46, and a first shaft 41a. A mainspring brake (output limiter) 54 for adjusting the rotation amount of the one shaft 41a is disposed. The output clutch 53 is the same type as the input clutch 51. In the present embodiment, the clutch mechanism 40 is configured by including the input clutch 51 and the output clutch 53.
The mainspring brake 54 is, for example, an electromagnetic brake, and allows or prohibits the rotation of the first shaft 41 a under the control of the control unit 22. The mainspring brake 54 can adjust the rotation amount of the first shaft 41a, and the elastic force stored in the mainspring spring 32 of the energy storage mechanism 34 can be continuously or stepwise in the range of 0% to 100%. Output as power. According to this, since the elastic force stored in the mainspring spring 32 is not output at a stretch and the output amount can be controlled, the acceleration and speed of the transport vehicle 10 can be controlled appropriately. Further, since the driving time of the winding motor 36 is reduced by suppressing the output amount, the power consumption for driving the winding motor 36 can be reduced, and energy saving can be realized.

The intermediate shaft 42 is pivotally supported on the plate 44 by a pair of bearing portions 55, 55 at both ends, and the fifth sprocket coupled to the intermediate shaft 42 via the third sprocket 50 and the chain 56. 57 and a sixth sprocket 59 connected to the fourth sprocket 52 through the chain 58, and a second one-way clutch 61 is disposed between the sixth sprocket 59 and the intermediate shaft 42. .
Similar to the first one-way clutch 49, the second one-way clutch 61 is engaged with the intermediate shaft 42 when the sixth sprocket 59 rotates in the forward direction, and the sixth sprocket 59 rotates in the reverse direction. Further, it is a mechanical clutch that slips when the above-described engagement is released.
Further, a seventh sprocket 63 is provided between the sixth sprocket 59 and the bearing portion 55, and the seventh sprocket 63 is provided with an eighth sprocket 67 (see FIG. 6) provided on the drive shaft 43 via a chain 65. ). Thereby, the rotational power of the main shaft 41 is transmitted to the drive shaft 43 via the intermediate shaft 42, and the auxiliary drive wheel 38 is driven.
Further, wheel brakes 69 and 69 for restricting the rotation of the intermediate shaft 42 are disposed on the intermediate shaft 42 between the fifth sprocket 57 and the sixth sprocket 59. These wheel brakes 69 and 69 are, for example, electromagnetic brakes, and reduce the rotation speed of the intermediate shaft 42 under the control of the control unit 22 or stop the rotation of the intermediate shaft 42 to increase the speed of the transport vehicle 10. Control.

As shown in FIGS. 3 and 5, the stacking unit 20 can move the mounting table 16 up and down in the vertical direction. The mounting table 16 is a table on which the work W is mounted. And a lifting device 60 that can be held at a desired height position.
The elevating device 60 includes a hydraulic cylinder (elevating mechanism) 64 that elevates and lowers the mounting table 16 via a rod 62 fixed to the substantially central lower surface of the mounting table 16, and a hydraulic circuit 66 that drives the hydraulic cylinder 64 (see FIG. 5). ). The up-and-down movement of the mounting table 16 is performed on the rail 70 extending in the vertical direction of the vehicle body parallel to the rod 62 on both sides in the vehicle width direction of the vertical plate 68 provided at the rear of the mounting table 16 and fixed to the vehicle body frame 24 side. 70 is guided by a guide recess 72 which is slidably engaged.

  As shown in FIG. 5, the hydraulic circuit 66 is connected to the upper chamber 64 a and the lower chamber 64 b of the hydraulic cylinder 64 defined by the piston 74 connected to the rod 62 via the control valve mechanism 76. The control valve mechanism 76 is a valve device that can appropriately switch the state of communication with the upper chamber 64 a and the lower chamber 64 b of the hydraulic circuit 66 and the flow direction of the hydraulic oil, and is driven and controlled by the control unit 22.

  Further, a pump 78 that pressurizes and flows the hydraulic oil in the circuit and a generator (generator) 80 that generates electric power by receiving the pressure and flow of the hydraulic oil are disposed in the hydraulic circuit 66. The electric power generated by the generator 80 is stored in an auxiliary battery 82 composed of a storage element such as a capacitor or a secondary battery, and then used as driving power for the pump 78. Note that the battery 12 can be used when the driving power of the pump 78 is insufficient with the power of the auxiliary battery 82 alone. It goes without saying that the electric power generated by the generator 80 may be stored in the battery 12 without providing the auxiliary battery 82. In this case, the conveyance vehicle 10 becomes light by the amount that the auxiliary battery 82 does not exist.

  Such a transport vehicle 10 travels with the main drive wheel 30 and the auxiliary drive wheel 38 being appropriately driven under the control of the control unit 22, but the vehicle body frame 24 (see FIG. 3), Wheels 84 a to 84 d that are driven and rotated by traveling by the main drive wheel 30 and the auxiliary drive wheel 38 are pivotally supported. The wheels 84a and 84b that are front wheels in the forward traveling direction of the transport vehicle 10 (the direction of the arrow in FIG. 1) may function as, for example, steering wheels that are steered under the control of the control unit 22. The wheels 84c and 84d, which are wheels, can be used as steering wheels.

  Further, for example, a magnetic field of a magnetic tape 86 (see FIG. 6) that is attached to a bottom surface side of the transport vehicle 10 on a route on which the transport vehicle 10 should travel in a factory and guides the transport vehicle 10 is detected. The sensor 88 (refer FIG. 3) which performs is provided, and the conveyance vehicle 10 can be magnetically guided by this. In addition to this, there are various methods for guiding the transport vehicle 10 such as a method of laying rails on the floor and guiding the transport vehicle 10 by this.

Next, the traveling operation of the transport vehicle 10 according to the present embodiment will be described.
The transport vehicle 10 basically travels (starts) using the auxiliary power unit 18 when starting from a stopped state under the control of the control unit 22, and travels using the main power unit 14 during normal travel after starting. Control is performed.
For example, when the transport vehicle 10 is stopped at a standby station or work stations 102a to 102c (FIG. 1), the battery 12 of the transport vehicle 10 is supplied from an external power supply 31 provided at the standby station or work stations 102a to 102c. It is charged. Here, when traveling (starting) is performed by the auxiliary power unit 18, the winding motor 36 connected to the external power source 31 is driven, and the mainspring 32 of the energy storage mechanism 34 is wound up by the driving force of the winding motor 36.
At this time, the control unit 22 puts the brake 35 in the released state (off) and the mainspring brake 54 in the activated state (on), while keeping the input clutch 51 and the output clutch 53 in the disconnected state (off). That is, by operating the mainspring brake 54, the first shaft 41a is fixed so as not to rotate, and the input clutch 51 is disengaged so that the rotational force is applied to the intermediate shaft when the second shaft 41b rotates. 42 is not transmitted.

  When the motor side coupling 21 of the hoisting motor 36 is engaged with the coupling 25 of the input shaft 27 and this hoisting motor 36 is driven, as shown in FIG. The mainspring 32 is transmitted to the second shaft 41b through the shaft 27, the first sprocket 37, the chain 39, the second sprocket 48 and the first one-way clutch 49, and the second shaft 41b rotates together with the casing 45. It is wound up on the first shaft 41a. In this state, an elastic force is generated in the mainspring spring 32 so as to rotate the second shaft 41b in the reverse rotation direction. For this reason, when the mainspring 32 is wound up, the control unit 22 operates (turns on) the brake 35 provided on the input shaft 27. As a result, the input shaft 27 and the second shaft 41b are fixed so as not to rotate in the reverse rotation direction, so that the winding motor 36 can be detached from the input shaft 27 by releasing the coupling. Thus, the energy storage mechanism 34 stores the power (rotational torque) of the winding motor 36 by converting it into the elastic force of the mainspring spring 32.

  Next, along with the charging of the battery 12 by the external power supply 31, after the storage of the elastic force in the energy storage mechanism 34 is completed, preparation for starting running (starting) is performed. That is, the control unit 22 keeps the output clutch 53 in a connected state (ON). As a result, the fourth sprocket 52 and the first shaft 41a are engaged with each other, and the fourth sprocket 52 can be rotated with the rotation of the first shaft 41a. Therefore, the power (rotational force) of the first shaft 41a is intermediate. The auxiliary drive wheel 38 can be transmitted to the auxiliary drive wheel 38 via the shaft 42 and the drive shaft 43. In this case, the holding by the mainspring brake 54 in which the first shaft 41a is in the rotation stopped state and the holding by the motor brake 36a in which the second shaft 41b is in the rotation stopped state are continued.

  When the mainspring brake 54 is released, as shown in FIG. 6B, the elastic force of the mainspring spring 32 is released, so that the first shaft 41a rotates vigorously. Accordingly, the rotational driving force of the first shaft 41a is transmitted through the fourth sprocket 52, the chain 58, the sixth sprocket 59, the second one-way clutch 61, the intermediate shaft 42, the seventh sprocket 63, the chain 65, and the eighth sprocket 67. When the drive shaft 43 is transmitted to the drive shaft 43 and rotated, the auxiliary drive wheel 38 rotates in the direction of moving the transport vehicle 10 forward, and the transport vehicle 10 can be started.

  In such starting by the auxiliary power unit 18, at least until the elastic force stored in the mainspring spring 32 is released, rotational torque is applied to the auxiliary drive wheel 38 by the rotation of the first shaft 41a. . Further, a second one-way clutch 61 is provided between the intermediate shaft 42 and the sixth sprocket 59. For this reason, even if the elastic force stored in the mainspring spring 32 is released and the rotational speed of the first shaft 41a becomes slower than the rotational speed of the intermediate shaft 42, the second one-way clutch 61 slips, The rotation of the shaft 42 and the drive shaft 43 is continued, and the transport vehicle 10 can travel a certain distance by the inertial force. Accordingly, by designing the vehicle body weight of the transport vehicle 10 including the weight of the work to be transported, the characteristics of the mainspring spring 32, the loss of each bearing portion, etc., for example, each work in the factory It is also possible to travel between the stations only by the elastic force stored in the mainspring 32 of the energy storage mechanism 34.

  Note that a clutch (not shown) is also provided between the drive shaft 28a of the travel motor 28 and the main drive wheel 30, and when the auxiliary power unit 18 is started, the glatch is in a disconnected state. It can also be set as As a result, it is possible to reduce the load on the traveling motor 28 that is not used at the time of starting, and to effectively suppress the load from the traveling motor 28 from affecting the starting operation.

  When the vehicle continues to travel after the start by the auxiliary power unit 18, the control unit 22 drives the main power unit 14 and drives the traveling motor 28 with the electric power from the battery 12. Traveling as an electric vehicle can be continued.

Subsequently, when the transport vehicle 10 is traveling, the control unit 22 performs an operation of regenerating the rotational power of the auxiliary drive wheel 38 to the mainspring 32 of the energy storage mechanism 34. In this case, it is desirable from the viewpoint of energy efficiency and the like to be performed when the transport vehicle 10 is decelerated rather than during traveling by the traveling motor 28.
When the transport vehicle 10 shifts to a deceleration operation, the control unit 22 turns the mainspring brake 54 into an operating state (on) and connects (turns on) the input clutch 51 to connect the third sprocket 50 and the second shaft. 41b is engaged. According to this, the rotational driving force of the auxiliary drive wheel 38 is transmitted via the drive shaft 43, the eighth sprocket 67, the chain 65, the seventh sprocket 63, the intermediate shaft 42, the fifth sprocket 57, the chain 56 and the third sprocket 50. Then, the mainspring 32 is wound around the first shaft 41a by being transmitted to the second shaft 41b and rotating the casing 45 together with the second shaft 41b.
As described above, in this configuration, by connecting the input clutch 51 while the transport vehicle 10 is traveling, the rotational drive force of the auxiliary drive wheel 38 can be regenerated (stocked) as the elastic force of the mainspring spring 32. For this reason, at the time of the next run, the winding motor 36 is driven at the station, and the spring force 32 of the energy storage mechanism 34 may be supplemented with the elastic force that is insufficient for the regenerated portion. Therefore, the power for storing the elastic force in the mainspring spring 32 can be reduced, the power consumption for driving the winding motor 36 can be reduced, and the power can be saved.

In general, in the case of storing an elastic force by winding a mainspring spring around a rotation shaft, the rotation direction of the rotation shaft is reversed between the storage of the elastic force and the output of the elastic force. For this reason, an elastic force is output to a shaft that rotates in a certain direction during normal travel (for example, forward travel), such as a drive shaft of a transport vehicle, and elastic force is output using the rotational drive force of this shaft. When regenerating is required, a mechanism for reversing the rotation axis of the mainspring spring is required between output and regeneration, which complicates the configuration.
In contrast, in this configuration, the energy storage mechanism 34 includes the divided first shaft 41a and second shaft 41b, and the mainspring spring 32 disposed between the shafts. The first shaft at the time of output for outputting the elastic force stored in the spring 32 to the auxiliary drive wheel 38 and at the time of regeneration for regenerating (stocking) the rotational drive force of the auxiliary drive wheel 38 as an elastic force to the mainspring spring 32. 41a and the second shaft 41b can be rotated in the same rotational direction. This eliminates the need for a mechanism for reversing the rotation of the rotating shaft and connecting it to the drive wheel during the storage (regeneration) of the elastic force and during the output, thereby simplifying the configuration of the energy storage mechanism.

  As described above, according to the transport vehicle 10 according to the present embodiment, the auxiliary drive wheel 38 can be driven by the elastic force stored by the mainspring spring 32 of the energy storage mechanism 34 to start from a stopped state. In this case, the winding motor 36 that winds up the mainspring spring 32 is driven by the external power source 31 when the transport vehicle 10 is stopped, so that it is not necessary to consume the battery 12 and can be performed at the same time as the battery 12 is charged. There will be no loss. Furthermore, after starting by the auxiliary power unit 18, the main power unit 14 can perform electric travel in the same manner as a general electric vehicle, so that a desired route can be traveled by a desired distance.

  In general, the amount of electric power (current amount) of the motor during low-speed rotation is larger than that during a predetermined high-speed rotation, and the driving torque required for starting from the stop is much larger than during steady running. In other words, if an attempt is made to start the transport vehicle 10 with the traveling motor 28, the traveling motor 28 must rotate at a low speed and output a high torque, and its power consumption is the mainspring. The power consumption of the winding motor 36 for winding the mimic 32 is extremely large.

  On the other hand, in the transport vehicle 10, since the start can be covered by the elastic force of the mainspring spring 32, a low-power and small-sized motor can be used as the traveling motor 28. In the transport vehicle 10 that also needs to be transported, the load related to starting is very large, and the effect is remarkable. Furthermore, in the transport vehicle 10, since it is not necessary to use the battery 12 at the time of starting, the capacity and size of the battery 12 can be reduced, and the transport vehicle 10 can be reduced in weight and power consumption. Moreover, since the mainspring spring 32 is used as the elastic body constituting the energy storage mechanism 34, the auxiliary power unit 18 can be configured easily and at low cost.

In the transport vehicle 10 according to the present embodiment, the main power unit 14 and the auxiliary power unit 18 are selectively driven as described above to travel, which enables significant power saving compared to a normal electric vehicle. Also, the lifting device 60 that constitutes the loading unit 20 on which the workpiece is loaded is also provided with the generator 80 and the auxiliary battery 82 described above, thereby further reducing power consumption.
That is, in the lifting device 60, before placing the workpiece W on the placing table 16, first, the control valve mechanism 76 is switched and the pump 78 is driven under the control of the control unit 22, and the hydraulic circuit 66 in FIG. Apply hydraulic pressure in the direction indicated by the dashed arrow P. Thereby, the lower chamber 64b is pressurized, and the mounting table 16 is raised to a desired height position via the piston 74.

Next, the work W is placed on the placing table 16. At this time, if the hydraulic pressure from the lower chamber 64b is prevented by the control valve mechanism 76 and the pressurized state is maintained, the driving of the work W can be easily and power-saving without maintaining the driving of the pump 78. The height position can be maintained.
When the work W is placed on the placing table 16 or when the work W held at the desired height position is lowered, the control valve mechanism 76 is appropriately controlled to appropriately control the pump 78. The mounting table 16 can be lowered by the weight of the workpiece W and the mounting table 16 without driving. That is, the control valve mechanism 76 is controlled to be switched so that the hydraulic oil can flow out from the lower chamber 64 b and the flowed hydraulic oil flows in the direction of the solid arrow Q in the hydraulic circuit 66. As a result, hydraulic oil flows from the lower chamber 64b compressed by the lowering of the piston 74 accompanying the lowering of the work W and the mounting table 16, and an impeller (not shown) of the generator 80 is rotated to generate electric power, and the electric power is supplemented. The battery 82 is charged.

  In the lifting / lowering device 60, the pump 78 is driven by the electric power from the auxiliary battery 82 stored in this way, and the mounting table 16 can be returned to the desired height position again. If the power from the auxiliary battery 82 is not enough, the battery 12 may be used together.

As described above, in the lifting device 60, power is generated by the generator 80 using the weight of the workpiece W and the mounting table 16, and is used as a drive source for the pump 78 used for re-raising the mounting table 16 via the auxiliary battery 82. be able to. That is, the lifting device 60 regenerates the potential energy of the workpiece W placed on the mounting table 16 at a desired height position as electric energy using the hydraulic circuit 66 and the generator 80, and charges the auxiliary battery 82. An energy regeneration mechanism is provided. For this reason, the energy required for raising / lowering the mounting table 16 can be basically covered by the raising / lowering device 60 itself.
Therefore, since the transport vehicle 10 includes the lifting device 60 having the energy regeneration mechanism described above, it is not necessary to use power from the battery 12 or the like as the lifting energy of the mounting table 16. For this reason, the capacity and size of the battery 12 can be further reduced, and further power saving of the transport vehicle 10 can be achieved.

  Further, as shown in FIG. 5, in the transport vehicle 10, the electric energy from the generator 80 regenerated by the lifting device 60 is not only used for charging the auxiliary battery 82, but, for example, the hoisting motor 36 of the auxiliary power unit 18. It can also be used as power for driving. As a result, when the transport vehicle 10 stops, for example, when the battery 12 does not need to be charged or when there is no external power supply 31 at the station where the vehicle is stopped, the power from the battery 12 is used. However, the hoisting motor 36 can be driven by the electric power from the auxiliary battery 82, and the elastic force can be stored in the energy storage mechanism 34.

  In addition, the mounting table 16 on which the workpiece W is placed is lowered at a desired timing when the vehicle is stopped, and the generator 80 generates electric power. It is also possible to store elastic force. In other words, when the transport vehicle 10 is stopped, the work W can be loaded and the elastic springs can be stored in the mainspring spring 32 substantially simultaneously, and after the work W is loaded, the auxiliary power unit 18 can start quickly. Become. For this reason, it is possible to further reduce power consumption and speed up the transfer work.

Next, a transport system 100 that is an application example of the transport vehicle 10 according to the present embodiment will be described. First, as shown in FIG. 7, the transport vehicle 10 waiting at the standby station 104 of the transport system 100 receives power supply from the external power source 31 to charge the battery 12 and also uses the driving force of the winding motor 36. The elastic force in the energy storage mechanism 34 is stored. After these operations are completed, the vehicle starts with the auxiliary power unit 18 as a drive source. The transported vehicle 10 that has started is guided to the magnetic tape 86 by the magnetic field detection by the sensor 88 under the control of the control unit 22, and arrives at the first work station 102a.
In this case, in the energy storage mechanism 34, the rotational driving force of the auxiliary driving wheel 38 is regenerated as an elastic force to the mainspring spring 32 when the transport vehicle 10 is decelerated. For this reason, in the work station 102a, the winding motor 36 is driven, and the spring spring 32 of the energy storage mechanism 34 may be supplemented with the elastic force that is insufficient for the regenerated portion. Therefore, the power for storing the elastic force in the mainspring spring 32 can be reduced, the power consumption for driving the winding motor 36 can be reduced, and the power can be saved.
In addition, if the distance between the standby station 104 and the work station 102a is a distance that can be sufficiently reached only by the power of the auxiliary power unit 18, it is not necessary to drive the main power unit 14 after the start, so that power is saved. The same applies to the movement at each work station below.

  Next, a work W such as an automobile engine is loaded on the transport vehicle 10 arriving at the work station 102a by a work robot 106a provided at the work station 102a. In the lifting device 60, energy regeneration is performed using the weight of the work W as necessary, and the auxiliary battery 82 stores the energy.

If power is generated by the lifting device 60 almost simultaneously with the loading of the workpiece W, the auxiliary motor 36 can be driven by the generated power, and the energy storage mechanism 34 can store elastic force. The external power supply 31 can be omitted from 102a.
The transport vehicle 10 loaded with the workpiece W starts with the auxiliary power unit 18 as a drive source and arrives at the second work station 102b. In the work station 102b, for example, a desired part (not shown) is assembled to the work W conveyed from the work station 102a by the work robot 106b.

  Subsequently, when the transport vehicle 10 arrives at the third work station 102c, for example, the work robot 106c unloads the workpiece W on which the desired parts are assembled from the mounting table 16. At the same time, the hoisting motor 36 is engaged with the input shaft 27, and elastic force is stored again in the energy storage mechanism 34 by the external power source 31.

  Thereafter, the transport vehicle 10 that has started from the work station 102 c travels on a route returning to the standby station 104 again. At this time, if the main power unit 14 is driven after the start by the auxiliary power unit 18, it can be easily returned even if the return path to the standby station 104 is a relatively long distance. The transport vehicle 10 that has returned to the standby station 104 receives power supply from the external power source 31 again as described above, and charges the battery 12 and stores the elastic force in the energy storage mechanism 34. Further, by driving the lifting device 60 by the auxiliary battery 82 charged at the work station 102a, the mounting table 16 can be raised to a desired height position.

As described above, in the transport system 100, since the transport vehicle 10 can move between the work stations and the like only by the power of the auxiliary power unit 18, the work can be performed with extremely low power consumption. Of course, the main power unit 14 can be driven as necessary during movement between the respective work stations.
Moreover, the transport vehicle 10 can also travel by the travel motor 28 in the same way as a normal electric vehicle. For this reason, even if it is a comparatively long driving | running route etc., it can move reliably, and the design freedom of a movement plan can be improved. Therefore, as shown by a broken line in FIG. 7, the traveling course of the transport vehicle 10 can be easily changed, for example, by simply replacing the magnetic tape 86 and slightly changing the control program of the control unit 22.

As described above, according to the present embodiment, the auxiliary drive wheel 38 of the vehicle body frame 24 is connected to the auxiliary drive wheel 38 and can be stocked by converting the power into an elastic force. The transport vehicle 10 having the energy storage mechanism 34 including the spring spring 32 that can output the power and the work stations 102a to 102c to which the transport vehicle 10 stops are provided in the work stations 102a to 102c. When the transport vehicle 10 stops at 102 to 102c, the transport vehicle 10 is connected to the energy storage mechanism 34 of the transport vehicle 10 and the winding spring 36 of the energy storage mechanism 34 stores power. There is no need to provide a winding motor 36 for writing the mainspring 32, and the weight of the transport vehicle 10 can be reduced and reduced. It is possible to realize a reduction.
Further, it is only necessary to supply a rotational driving force from the winding motor 36 of each work station 102a to 102c to the energy storage mechanism 34 of the transport vehicle 10 via the input shaft 27. The elastic force can be stored in 32. Furthermore, since each work station 102a-102c is equipped with the winding motor 36 instead of each conveyance vehicle 10, when the number of work stations is smaller than the number of conveyance vehicles, the number of electric motors to be arranged is reduced and low. System configuration is possible at low cost.

Further, according to the present embodiment, the transport vehicle 10 outputs power from the mainspring spring 32 of the energy storage mechanism 34 to the auxiliary drive wheels 38 of the vehicle body frame 24 and regenerates power from the auxiliary drive wheels 38 to the mainspring springs. When moving between the work stations 102a to 102c, the vehicle travels with the power stored in the energy storage mechanism 34, and the clutch mechanism 40 is switched to the regenerative side while traveling, and the auxiliary drive wheel while traveling Since the power can be regenerated from the main spring to the mainspring spring 38, the power of the traveling auxiliary drive wheel 38 is regenerated as an elastic force to the mainspring spring 32 of the energy storage mechanism 34 by switching the clutch mechanism 40. be able to.
For this reason, in the work station, the winding motor 36 may be driven to replenish the mainspring spring 32 of the energy storage mechanism 34 with an elastic force that is insufficient for the regenerated portion. Therefore, the power for storing the elastic force in the mainspring spring 32 can be reduced, the power consumption for driving the winding motor 36 can be reduced, and the power can be saved.

  Further, according to the present embodiment, the main drive wheel 30 that drives the vehicle body frame 24 and the traveling motor 28 that drives the main drive wheel 30 are provided, and the power stored in the mainspring spring of the energy storage mechanism 34 is Since the driving force of the traveling motor 28 is assisted when the vehicle is started, the traveling motor 28 having a low output and a small size can be used, and the transport vehicle 10 can be reduced in weight and power consumption. Further, near the end point of the distance between each work station, the clutch mechanism 40 is switched to the regeneration side so that power can be regenerated from the auxiliary drive wheel 38 to the mainspring spring 32 while traveling. The winding motor 36 may be driven to replenish the mainspring spring 32 of the energy storage mechanism 34 with an elastic force that is insufficient for the regenerated portion. Therefore, the power for storing the elastic force in the mainspring spring 32 can be reduced, the power consumption for driving the winding motor 36 can be reduced, and the power can be saved.

  Note that the present invention is not limited to the above-described embodiment, and it is needless to say that various configurations can be adopted without departing from the gist of the present invention. For example, in the present embodiment, the description has been given of the configuration in which the transport vehicle 10 includes the main power unit 14 having the traveling motor 28 and uses the energy storage mechanism 34 as an auxiliary at the time of starting. If the distance traveled is determined in advance, the energy storage mechanism 34 may be designed to meet the conditions so that the main power unit 14 is not provided.

  In addition, although the transport vehicle 10 of the present embodiment is configured to include the travel motor 28 as the travel drive source in the main power unit 14, other drive sources such as an internal combustion engine such as an engine or a mainspring drive can be used. Of course. In the present embodiment, the battery 12 is provided as a power supply unit that supplies power to the traveling motor 28. For example, a power overhead line is provided on the floor surface or the like, and the traveling motor is provided via the power overhead line. A configuration for supplying electric power may be used. In addition, instead of charging the battery 12 with only an external power source, for example, a solar panel may be provided in the transport vehicle, and the solar panel and the external power source may be used in combination.

  In the present embodiment, the electric hoisting motor is provided as the stockpiling drive source. However, the present invention is not limited to this. For example, an impact wrench may be used as long as the second shaft 41b is provided with a rotational driving force. Alternatively, an air motor that is driven to rotate using compressed air as a power source may be used.

  Moreover, in this embodiment, although the energy storage mechanism 34 has the casing 45 connected with the 2nd shaft 41b, it is good also as a structure connected with the 1st shaft 41a. Furthermore, in the present embodiment, the cylindrical casing 45 is fixed to the second shaft 41b. However, if the configuration extends in parallel with the shaft end of the first shaft 41a, the shaft end of the second shaft 41b. It is good also as a structure which fixes a substantially L-shaped member to this.

  In the transport vehicle 10, the driving power obtained by the main power unit 14 including the traveling motor 28 and the main driving wheels 30 driven by the electric power from the battery 12 is used to start and maintain a constant speed as in a general electric vehicle. Needless to say, the vehicle may be configured to perform normal driving by driving and accelerating. That is, since the transport vehicle 10 can travel substantially the same as a general electric vehicle, it is of course possible to reverse (back) and the like, thereby further improving the degree of freedom of the configuration of the transport system 100 and the like. it can.

  Further, the auxiliary power unit 18 including the energy storage mechanism 34 and the like is configured as a towing vehicle (push wheel) configured separately from the main power unit 14, and the transport vehicle including the main power unit 14 and the loading unit 20 is provided. It can also be externally attached to be pulled or pushed, so that the function of the auxiliary power unit 18 can be easily added to the existing AGV or the like.

  Furthermore, it is needless to say that the transport vehicle 10 can be configured as an electric vehicle in which another load is transported and a person rides instead of transporting the workpiece W or the like, with the loading unit 20 omitted.
