In the elevator 20, when the extending direction is inclined or when the building A is inclined, the roller 41 b of the guide roller 41 contacts the guide surface 42 a of the guide portion 42.

  Further, the transport device 1 includes a controller 50 (FIG. 7) for controlling the operations of the slide arm 14 and the elevator 20. The controller 50 has a CPU, ROM, RAM, and the like. When the controller 50 receives an input signal from a device connected to the input side, the CPU reads a program stored in the ROM based on the input signal, and stores a state detected by the input signal in the RAM. An output signal is transmitted to a device connected to the output side.

  On the input side of the controller 50, as shown in FIG. 7, an operation input unit 51 for an operator to input related to the operation of the transport device 1, and a jack full extension sensor for detecting the full extension state of the elevator 20. 52, an arm full contraction sensor 53 as an arm state detection unit for detecting a full contraction state in which the slide arm 14 is stored, and a full extension state in which the slide arm 14 is extended are detected. An arm full extension sensor 54 as an arm state detection unit for performing the above operation, an arm seating sensor 55 as an arm state detection unit for detecting a seating state in which the slide arm 14 is engaged with the deck receiving unit 100, Is connected.

  The jack full extension sensor 52 is a limit switch provided at the upper end of the top jack of the elevator 20 as shown in FIGS. 1 and 2, and the elevator 20 is in the fully extended state on the roof of the building A. A detected portion 52a is provided for operating the.

  As shown in FIG. 6, the arm full contraction sensor 53 is a limit switch provided inside the deck 10, and is operated by an operation piece 14 b provided at the base end of the slide arm 14 when the slide arm 14 is fully contracted. Operated.

  As shown in FIG. 6, the arm full extension sensor 54 is a limit switch provided inside the deck 10, and is operated by the operation piece 14 b when the slide arm 14 is fully extended.

  As shown in FIG. 6, the arm seating sensor 55 is a limit switch provided at the upper part of the opening where the slide arm 14 on the side surface of the deck 10 protrudes, and the slide arm 14 is engaged with the deck receiving unit 100. The slide arm 14 is operated by moving the tip part slightly upward.

  As shown in FIG. 7, a control valve 56 for controlling the operation of the arm retracting cylinder and the first to third jack cylinders of each elevator 20 is connected to the output side of the controller 50.

  In the transport apparatus configured as described above, a transport operation for transporting the transport target T in the vertical direction will be described.

  First, in the fully contracted state in which the elevator 20 is fully contracted, the placement surface 11 of the deck 10 is approximately the same height as the floor surface of the second floor of the building A as shown in FIG. . In this state, the transfer work T of the conveyance target T is performed from the second floor of the building A to the deck 10.

  When the deck 10 located on the second floor of the building A is moved to the roof, the elevator 20 is extended. Each elevator 20 performs the extension operation of the second jack 22 with respect to the base jack 21, the extension operation of the third jack 23 with respect to the second jack 22, and the extension operation of the top jack 24 with respect to the third jack 23 while synchronizing the extension operations with each other. It becomes a stretched state.

  Moreover, when moving the deck 10 located on the roof of the building A to the second floor, each elevator 20 in the fully extended state is reduced. Each elevator 20 performs a reduction operation of the top jack 24 with respect to the third jack 23, a reduction operation of the third jack 23 with respect to the second jack 22, and a reduction operation of the second jack 22 with respect to the base jack 21 while synchronizing the reduction operations with each other. It becomes a contracted state.

  When the elevator 20 is performing the extension operation or in the fully extended state, the transfer device 1 is shaken due to the deviation of the center of gravity of the deck 10 on which the transfer object T is placed, or the building A and the transfer device are caused by an earthquake or strong wind. 1, the roller 41 b of the guide roller 41 provided at the upper end of the third jack 23 of the elevator 20 guides the guide 42 provided on the wall surface of the shaft B near the roof of the building A. Since it contacts the surface 42a, it is prevented that parts other than the guide roller 41 of the conveying apparatus 1 contact structures other than the guide part 42 of the building A.

  Further, during the transport operation of the transport device 1, the controller 50 performs an operation control process for the telescopic operation of each elevator 20 and the telescopic operation of the slide arm 14. An example is shown in FIG.

(Step S1)
In step S <b> 1, the CPU determines whether or not an operation for raising the deck 10 is performed on the operation input unit 51. If it is determined that an operation to raise the deck 10 has been performed, the process proceeds to step S2. If it is not determined that an operation to raise the deck 10 has been performed, the process proceeds to step S12.

(Step S2)
When it is determined in step S1 that the operation for raising the deck 10 has been performed, in step S2, the CPU determines whether or not the slide arm 14 is in a fully contracted state. If it is determined that the slide arm 14 is in the fully contracted state, the process proceeds to step S3. If it is not determined that the slide arm 14 is in the fully contracted state, the operation control process is terminated.
Here, the fully contracted state of the slide arm 14 is detected by the controller 50 receiving the output signal of the arm fully contracted sensor 53. The case where it is not determined that the slide arm 14 is in the fully contracted state indicates a state in which the slide arm 14 is overhanging and the deck 10 is supported by the deck receiving portion 100 of the building A. For this reason, the controller 50 does not perform the extension operation of the elevator 20 even when the operation input unit 51 is operated to raise the deck 10.

(Step S3)
When it is determined in step S2 that the slide arm 14 is in the fully contracted state, in step S3, the CPU performs the extending operation of the elevator 20 and moves the process to step S4.

(Step S4)
In step S4, the CPU determines whether or not the elevator 20 is fully extended. If it is determined that the elevator 20 is fully extended, the process proceeds to step S5. If it is not determined that the elevator 20 is fully extended, the process proceeds to step S2.
Here, the full extension state of the elevator 20 is detected by the controller 50 receiving the output signal of the jack full extension sensor 52.

(Step S5)
When it is determined in step S4 that the elevator 20 is in the fully extended state, in step S5, the CPU performs the extension operation of the slide arm 14, and moves the process to step S6.
Here, the projecting operation of the slide arm 14 is performed in a state where the slide arm 14 is positioned above the upper surface of the deck receiving portion 100 as shown in FIG.

(Step S6)
In step S6, the CPU determines whether or not the slide arm 14 is fully extended. If it is determined that the slide arm 14 is fully extended, the process proceeds to step S7. If it is not determined that the slide arm 14 is fully extended, the process proceeds to step S4.
Here, the full extension state of the slide arm 14 is detected by the controller 50 receiving the output signal of the arm full extension sensor 54.

(Step S7)
When it is determined in step S6 that the slide arm 14 is in the fully extended state, in step S7, the CPU performs a reduction operation of the elevator 20 and moves the process to step S8.
As a result, the slide arm 14 protruding from the deck 10 moves toward the deck receiving unit 100 as shown in FIG. Here, when the slide arm 14 is in the fully extended state, the operating speed of the elevator 20 is set to be lower than the operating speed of the elevator 20 in the fully contracted state.

(Step S8)
In step S <b> 8, the CPU determines whether or not the slide arm 14 is in a sitting state in which the slide arm 14 is supported by the deck receiving unit 100. If it is determined that the slide arm 14 is in the sitting state, the process proceeds to step S9. If it is not determined that the slide arm 14 is in the sitting state, the process proceeds to step S7.
Here, the seating state of the slide arm 14 is detected when the controller 50 receives the output signal of the arm seating sensor 55.

(Step S9)
When it is determined in step S8 that the slide arm 14 is in the sitting state, in step S9, the CPU measures the time after the slide arm 14 is in the sitting state, and moves the process to step S10.

(Step S10)
In step S <b> 10, the CPU determines whether or not a predetermined time has elapsed since the slide arm 14 is seated. If it is determined that the predetermined time has elapsed, the process proceeds to step S11. If it is not determined that the predetermined time has elapsed, the process proceeds to step S9.
Here, the predetermined time is a time required for the operation of lowering the elevator 20 by a predetermined distance (for example, 20 mm) with respect to the deck 10 supported by the building A when the slide arm 14 is seated on the deck receiving unit 100. It is. At this time, as shown in FIG. 11, the pin 32a of the suspension part 32 of the deck suspension member 30 moves downward in the long hole 33a of the connection support member 33 (for example, the pin 32a moves in the long hole 33a). Move down 20mm for possible range 150mm).
Thereby, the deck 10 can be supported by the building A independently from the elevator 20, and the elevator 20 is naturally raised (for example, 20 mm) or lowered (for example, 20 mm) due to a temperature change of a hydraulic circuit that drives the elevator 20 or leakage of hydraulic oil. For example, 130 mm) can be absorbed.

(Step S11)
When it is determined in step S10 that the predetermined time has elapsed, in step S11, the CPU stops the reduction operation of the first to fourth elevators and ends the operation control process.

(Step S12)
If it is not determined in step S1 that the operation for raising the deck 10 has been performed, in step S12, the CPU determines whether or not an operation for lowering the deck 10 has been performed on the operation input unit 51. If it is determined that an operation for lowering the deck 10 has been performed, the process proceeds to step S13. If it is not determined that an operation for lowering the deck 10 has been performed, the operation control process is terminated.

(Step S13)
When it is determined in step S12 that the operation of lowering the deck 10 has been performed, in step S13, the CPU determines whether or not the slide arm 14 is in a fully extended state. If it is determined that the slide arm 14 is fully extended, the process proceeds to step S14. If it is not determined that the slide arm 14 is fully extended, the operation control process is terminated.
Here, the full extension state of the slide arm 14 is detected by the controller 50 receiving the output signal of the arm full extension sensor 54. Moreover, the case where it is not determined that the slide arm 14 is in the fully extended state indicates that the slide arm 14 is stored and the deck 10 is located on the second floor of the building. For this reason, the controller 50 does not perform the expansion / contraction operation of the elevator 20 even when the operation input unit 51 is operated to lower the deck 10.

(Step S14)
When it is determined in step S13 that the slide arm 14 is in the fully extended state, in step S14, the CPU performs the extending operation of the elevator 20 and moves the process to step S15.
Here, when the slide arm 14 is in the fully extended state, the operating speed of the elevator 20 is set to be lower than the operating speed of the elevator 20 in the fully contracted state. As a result, the slide arm 14 protruding from the deck 10 moves at a slow speed in a direction away from the upper surface of the deck receiving unit 100 as shown in FIG.

(Step S15)
In step S15, the CPU determines whether or not the elevator 20 is in the fully extended state. If it is determined that the elevator 20 is fully extended, the process proceeds to step S16. If it is not determined that the elevator 20 is fully extended, the process proceeds to step S13.
The full extension state of the elevator 20 is detected when the controller 50 receives the output signal of the jack full extension sensor 52. In addition, the fact that the elevator 20 is in the fully extended state indicates that the seating state of the slide arm 14 with respect to the deck receiving unit 100 is released.

(Step S16)
When it is determined in step S15 that the elevator 20 is in the fully extended state, in step S16, the CPU performs the storing operation of the slide arm 14, and the process proceeds to step S17.
Here, as shown in FIG. 13, the slide arm 14 is stored away from the deck receiving unit 100.

(Step S17)
In step S17, the CPU determines whether or not the slide arm 14 is in a fully contracted state. If it is determined that the slide arm 14 is in the fully contracted state, the process proceeds to step S18. If it is not determined that the slide arm 14 is in the fully contracted state, the process proceeds to step S15.
Here, the fully contracted state of the slide arm 14 is detected by the controller 50 receiving the output signal of the arm fully contracted sensor 53.

(Step S18)
When it is determined in step S17 that the slide arm 14 is in the fully contracted state, in step S18, the CPU performs a reduction operation of the elevator 20 and ends the operation control process.
As a result, the deck 10 is lowered without the slide arm 14 coming into contact with the deck receiving portion 100 as shown in FIG.

  As described above, according to the transport device of the present embodiment, each configuration has the respective effects. First, a deck 10 on which the conveyance target T is placed and a plurality of elevators 20 which are provided so as to be extendable in the vertical direction and support the deck 10 in a suspended state and move in the vertical direction are provided.

  As a result, the height dimension of the deck 10 can be set freely, so that the minimum height dimension of the deck 10 can be set according to the installation conditions of the installation location regardless of the height dimension of the elevator 20. Is possible.

  Further, the deck 10 moved to a predetermined height position by the elevator 20 is suspended from the elevator 20 by the deck suspension member 30 connected by the pin 32a of the suspension part 32 and the long hole 33a of the connection support part 33. It is made to lock to Building A independently from 20.

  Thereby, the deck 10 can be reliably held at a predetermined height position. In addition, as in the case where the height position of the deck 10 is held by a plurality of elevators 20, it is possible to prevent the mounting surface 11 of the deck 10 from being inclined due to different reduction lengths of the elevators 20. It is possible to hold the mounting surface 11 of the deck 10 on the horizontal plane. Further, even when the height position of the deck 10 is held for a long time by closing the hydraulic circuit that drives the elevator 20, the weight of the deck 10 or the transport object T placed on the deck 10 is maintained. It is possible to prevent the vertical movement of the deck 10 by the elevator 20 that contracts or expands due to leakage of minute hydraulic oil in the hydraulic circuit or temperature change due to the weight of the lift.

  Further, the building 10 has a slide arm 14 that can be moved in and out from the deck 10 toward the building A, and the building A is provided with a deck receiving portion 100 that receives the slide arm 14 protruding from the deck 10 from below.

  Accordingly, the deck 10 can be locked to the building A with a simple structure, and the manufacturing cost can be reduced.

  Further, an arm full contraction sensor 53, an arm full extension sensor 54, and an arm seating sensor 55 for detecting the state of the slide arm 14 with respect to the deck 10 are provided.

  Thereby, since it is possible to prevent the lifting and lowering operation of the elevator 20 with the slide arm 14 overhanging, the slide arm 14 can be prevented from contacting the building A, and the building A and the transfer device 1 can be prevented. Can prevent damage.
