Description

  The present invention allows a person to enter a closed area where it is not preferable for a person to enter, for example, a predetermined area such as a warehouse or an elevator car (carrying device) without entering, or a person not to enter the area. The present invention relates to a transporting apparatus and a transporting method for carrying out the load from the area.

  Conventionally, in the work of loading and unloading luggage into a closed area where people are not preferred to enter, such as elevators and warehouses, personnel enter all or part of the body into the area and load the luggage. Or work to carry out.

  In particular, in an elevator, when a person enters the car when carrying in or out the luggage, an excessive force acts on the car, and there is a possibility that the person will come into contact with the car that is running. In addition, in the elevator, when a car with a loading platform travels, the car is shaken by the shaking during traveling, and it can collide with the car wall, etc., and it can cause effects such as collapse of the cargo and movement of the loading platform. There is sex.

  Some of these issues are resolved exclusively for each individual issue. For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2000-44150) is an elevator for carrying goods, and a movable floor is provided on a fixed floor of a car in order to facilitate carrying in / out of goods such as paper rolls. Thus, there is provided means for moving the floor rear end up and down.

  Patent Document 2 (Japanese Patent Application Laid-Open No. 2014-1008864) is a general elevator in which a loading platform and a wheelchair get on and off with a general user, and by installing a device for driving and controlling the car floor height during traveling in a car, Means for suppressing the movement of the cargo bed due to the vibration of.

Next, on the floor F2, the worker L2 causes the self-propelled carriage 2 stopped in the elevator car EL to travel by remote operation of the self-propelled caster 24, and retreats from the elevator car EL. At this time, the disc portion of the fixing mechanism 26 is retreated upward by remote control to lower the self-propelled portion 21 so that the self-propelled portion caster 24 comes into contact with the floor surface. The carriage 2 is allowed to move freely back and forth and left and right. As a result, the unloading step of unloading the self-propelled carriage 2 carrying the luggage 4 out of the elevator car EL is completed on the floor F2.

  Next, on the floor F2, the worker L2 connects the self-propelled carriage 2 retracted from within the elevator car EL to the base unit 3B disposed in the elevator hall of the floor F2 by remote operation, and from above the self-propelled carriage 2 Carry out the loading process to unload the luggage. When shipping, the procedure shown in FIG. 17 is reversed.

  Specifically, as shown in FIGS. 17C to 17A, in the floor F2, first, the worker L2 places the self-propelled carriage 2 retracted from the elevator car EL in the elevator hall of the floor F2. The base unit 3B is connected to the base unit 3B by remote control, the platform 22 is raised along the lifting mechanism 37, and the platform 22 is coupled to the work table 32. Further, at this time, the disk portion of the rotating mechanism 36 is protruded downward by remote control, so that the cart unit 31 is raised, and the caster 34 is separated from the floor surface. Next, the work platform 32 is rotated horizontally by human power with the loading platform 22 connected to the carriage 31 by the rotation mechanism 36 provided on the lower surface of the carriage 31 so that the loading platform 22 faces the worker L2 side. Like that. In this state, the worker L2 can carry out the loading work of the load 4 while facing the loading platform 22 at a position separated from the elevator car EL. In this case, the worker L2 can perform the loading operation in a situation where there is no risk of contact with the elevator car EL.

(Action / Effect)
According to the present embodiment described above, for example, the work of loading / unloading luggage into / from the elevator car EL is facilitated, the burden and danger at the time of loading / unloading the luggage are reduced, and the elevator travels It is possible to suppress the collapse of cargo and the movement of luggage.

  Since the base unit 3 is disposed on each floor of the floor where the base unit 3 is carried in and the floor where the base unit 3 is carried out (base units 3A and 3B), a complicated remote operation is not required, and the lifting mechanism 37 provided with the base of the self-propelled carriage on the base unit is provided. By moving up and down, the self-propelled carriage lifting mechanism 27 can be omitted. As a result, this embodiment can reduce the weight of the self-propelled carriage and increase the load capacity of the load by one transport compared to the embodiment 1A, and the worker L1 and the worker L2 can work. In this case, it is possible to further reduce the risk of contact with the elevator car EL.

(Modification 1)
The above description of the embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiments, and various modifications including applications can be made according to the design and the like as long as they do not depart from the technical idea according to the present invention.

  For example, as shown in FIG. 18, when loading and unloading a plurality of loads on a plurality of floors via an elevator car EL, the base unit 3 is disposed only on the floor (floor F1 in the illustrated example) on which loading is performed. be able to. Thereby, at the time of loading on the floor F1, the worker L1 uses the base unit 3 to carry into the elevator car EL, and on each destination floor, for example, the floor 2F, the worker L2 uses only the operating device 52. Carry out.

  According to this, on the floor where the loading work is concentrated (here, floor F1), the base unit 3 is used to carry in efficiently, and on the other floor where the work such as loading is distributed (here, floor F2), the operating device. Only 52 is arranged, the overall equipment cost is reduced, and even if the elevator hall on the target floor is a relatively narrow space, it is possible to work efficiently while reducing the danger. In this case, the lifting / lowering function of the loading platform can be provided with both the self-propelled cart lifting / lowering mechanism 27 and the lifting / lowering mechanism 37, or one of them can be omitted to further simplify the equipment.

(Modification 2)
In addition, the transport device according to the present invention can be used as a transport method for facilitating the work of loading / unloading luggage into / from a predetermined area of the warehouse WH where entry of people is not preferable, for example. . In this case, the fixing mechanism 26 provided in the self-propelled carriage 2 can be omitted. FIG. 19 is a diagram illustrating an external configuration of a second modification according to the first embodiment.

(Modification 3)
Further, in the above-described embodiment, the self-propelled carriage 2 is configured as a carriage that carries luggage according to the purpose of carrying in or out the luggage 4 to or from an elevator or a warehouse. For example, in a mechanical parking device that accommodates a vehicle and is parked by transporting the vehicle by a pallet (carriage) as shown in FIGS. However, the vehicle 40 may be transported into the apparatus without entering the apparatus.

  In a general mechanical parking apparatus, a plurality of pallets PL on which the vehicle 40 is placed are installed in a storage space called a pit so as to be movable. In this pit PT, a vehicle approaching path to the pallet PL is provided, for example, on the ground floor F0 so as to face the pallet PL. The vehicle 40 enters the pallet PL from the vehicle approaching path and is placed on the pallet PL. The pallet PL is moved up and down, rotated, or moved left and right to be transferred to a predetermined position in the pit PT, and can be stored in a three-dimensional manner by allowing it to be parked in the vertical direction. In this modified example, when the vehicle 40 is placed on and removed from the pallet PL, the driver or passenger of the vehicle 40 avoids entering the pallet PL while riding on the vehicle 40, and When the pallet PL moves in the pit PT, the vehicle 40 placed on the pallet PL is prevented from moving from the stop position due to vibration, thereby smoothly and safely transporting the vehicle 40 in the pit PT. The gist is to do.

  The modified example 3 will be described in detail with reference to the accompanying drawings. FIG. 20 is a perspective view (a) showing the usage state of the transport device according to the modified example, a side view (b) showing the external configuration, and a bottom view (c). FIG. 21 is a perspective view showing a procedure for using the transport device according to the present modification. In this modification, the self-propelled carriage described in the above embodiment is a vehicle self-propelled carriage 20 having a size and a shape that allows entry and placement on the pallet PL as shown in FIG. . The vehicle self-propelled carriage 20 is configured to travel forward and backward by driving a caster 24 provided on the lower surface of the self-propelled portion 21, and is mounted on the loading platform portion 22 provided on the upper surface of the self-propelled portion 21. The vehicle 40 can be placed. In addition, a deck 28 is provided at the end of the self-propelled portion to facilitate placing the vehicle on the loading platform 22. Furthermore, a fixing mechanism 26 is provided on the lower surface of the self-propelled portion 21 to prevent the vehicle placed on the pallet PL from moving from the stop position due to vibration when the pallet PL moves up and down in the pit PT. Can be done.

  Then, as shown in FIG. 21, in the vehicle approach path in front of the pit PT, the driver and passengers get off the vehicle 40, and the driver performs a remote operation with the operation device to lower the tip of the deck 28 and move to the floor surface. It is made to adhere to (Figure (a)). In this state, the driver drives the vehicle 40 and places the vehicle 40 on the loading platform 22. Next, the driver gets out of the vehicle 40 and the loading platform 22, and raises the tip of the deck 28 horizontally by remote control ((b) in the figure). In this state, the driver moves the vehicle self-propelled carriage 20 on which the vehicle 40 is placed on the pallet PL by remote control, and stops the pallet PL (FIG. 3C). Thereby, the vehicle approach process in the case of warehousing is complete | finished.

  At this time, the driver causes the fixing mechanism 26 provided on the lower surface of the self-propelled portion 21 to project downward by remote control and adheres to the floor surface of the pallet PL. In this state, when the pallet PL on which the vehicle is placed moves in the pit PT, the fixing mechanism 26 prevents the vehicle 40 placed on the vehicle self-propelled carriage 20 from moving from the stop position due to vibration. can do.

When leaving the car, the pallet PL on which the vehicle 40 is placed stops at the entrance of the parking device facing the vehicle approach path provided on the ground floor FO, for example. The provided fixing mechanism 26 is retracted upward to leave the floor surface. In this state, the warehousing procedure shown in paragraph 0067 and FIG. As a result, the vehicle self-propelled carriage 20 on which the vehicle 40 is placed is withdrawn from the pallet PL by remote control, and the carrying-out process is performed. Thereafter, on the vehicle approach path before the pallet PL, the driver lowers the tip of the deck 28 by remote operation and drives the vehicle 40 placed on the loading platform 22 to make the vehicle 40 a self-propelled carriage 20 for a vehicle. The unloading process is completed.

  Thus, according to this modified example, in the mechanical parking device, the driver or passenger does not enter the pallet PL or pit PT together with the vehicle 40, and the vehicle 40 is stored and exited in the pallet PL. When the vehicle 40 placed on the pallet PL is transported by power in the pit PT, the movement of the vehicle 40 due to vibration can be suppressed. Thereby, an accident can be prevented when the vehicle 40 enters and leaves the apparatus, and the smoothness and safety of transportation of the vehicle 40 can be improved.
