The drive conveyor 6a is connected to the inclined upper end of the cargo flow support portion to be stored. In this state, the drive conveyor 6a is driven in the direction in which the load is conveyed to the side where the rack 3 to be stored is present, and the load flow support portions 14a to 14d to be stored on the shelf boards 7a to 7n having the height to be stored. It is sent out on the upper end of the slope. Thus, the load flows downward on the two rows of roller rails 13 constituting the load flow support portions 14a to 14d by gravity, and the load receiving member 15 at the lower end of the tilt or the load flow support portions 14a to 14d already exists. Since it abuts on the rear side of the load supported above and stops, the load is supported on the load flow support portions 14a to 14d of the respective shelf plates 7a to 7n in an upward direction from the inclined lower end. Become.

  The removal of the load is inclined from the front side of the rack 3, that is, the side opposite to the side where the traveling passage 2 of the storage crane 1 is located, from above the load flow support portions 14a to 14d of the shelves 7a to 7n of the respective stages. This is done by picking up in order from the load located at the lower end.

  In the rack equipment used as described above, when it is necessary to change the height between the shelf boards 7b to 7n to change the distance between the upper and lower shelf boards, that is, the height of the load storage space, for example, FIG. As shown by the left rack 3, the load storage space between the two shelf plates 7b, 7c in the middle stage is eliminated, and the height of the load storage space on the shelf plate 7c is increased as follows. The height of the shelf boards 7b and 7c can be changed. In this case, the shelf board 7b is temporarily lowered, the shelf board 7c is lowered to the vicinity of the height at which the shelf board 7b is located, and the shelf board 7b is raised to a position directly below the lowered shelf board 7c, thereby the shelf board 7c. The height of the load storage space is expanded.

  For example, when it is desired to change the height of the shelves 7b / 7c as described above, the drive conveyor 6a on the lifting carriage 6 of the cradle crane 1 is removed, and the multistage stretching movement is performed on the lifting carriage 6 instead of the driving conveyor 6a. The shelf board support 50 is attached via the body 51. As shown in FIGS. 3 and 8, the upper surface of the shelf support base 50 is inclined at the same angle as the shelf plates 7 a to 7 n installed on the rack 3. When the shelf support 50 is mounted on the lifting carriage 6 via the multistage telescopic moving body 51 depending on whether the rack 3 with 7b / 7c is on the left or right side of the traveling path 2 of the crane 1 for storage. Therefore, the orientation of the top surface of the shelf support 50 must be determined so that the slope of the shelf plate 7b / 7c to be changed in height becomes equal.

  As described above, if the shelf support 50 is attached to the lifting carriage 6 of the crane 1 for storage via the multistage telescopic moving body 51, the multistage telescopic mobile 51 is contracted and the shelf support 50 is reduced. In the home position on the lifting / lowering carriage 6, the traveling crane 1 is moved and the lifting / lowering carriage 6 is moved up and down, and the shelf support 50 is moved to the shelf 7b / 7c is moved to a position where it can enter the lower side. Next, as shown in FIGS. 3 and 8, the multistage telescopic movable body 51 is extended, and the shelf board support base 50 is advanced to a predetermined position below the shelf boards 7 b / 7 c to be changed in height. In this state, the elevating carriage 6 is raised and the shelf board 7b / 7c that is the height change work target is supported by the shelf board support base 50. Specifically, the locking members 16a to 17b included in the shelf plate 7b / 7c are within the range of play between the locked holes 18 on the shelf plate support frames 8a and 8b (support members 9a and 9b) side. A state where the load of the shelf boards 7b / 7c acts on the shelf board support base 50 is raised slightly. As a result, the pair of front and rear pushers 54a and 54b projecting upward from both front and rear sides of the shelf support base 50 enter the inside of the shelf 7b / 7c. In addition, the to-be-latched holes 18 on the side of the shelf support frames 8a and 8b (support members 9a and 9b) are long and long in the vertical direction so that the shelf support 7b supports the shelf 7b / 7c. In this state, the raising / lowering control of the lifting carriage 6 is facilitated.

  Next, the cylinder 61 of the driving means 55 of the operating means driving device 53 provided in the shelf board support base 50 is operated as described above, and the pair of front and rear pushers 54a and 54b are synchronized with each other in a direction away from the retreat limit position. By moving forward, as shown in FIG. 7B, the pair of front and rear pushers 54a and 54b come into contact with the machine operation section 52 at the center of the pair of front and rear operation levers 23a and 23b included in the shelf board 7b / 7c. Both operating levers 23a and 23b are pressed and moved in a direction away from each other against the compression coil spring 29 of the support means 27. As a result, the cord-like bodies 30a and 30b of the interlocking means 24 and the cord-like bodies 34a and 34b of the interlocking means 25 are pulled, and all the locking members 16a to 17b respectively resist the biasing force of the compression coil spring 20, The shelf support frames 8a and 8b are pulled out from the locked holes 18 of the column members 9a and 9b. When the shelf boards 7b / 7c are thus separated from the shelf support frames 8a and 8b, the lifting carriage 6 is lowered to bring the shelf boards 7b / 7c supported by the shelf support base 50 to the target level. Move up and down vertically.

  If the shelf board 7b / 7c is moved up and down to a target level, the two locking members 16a to 17b on the left and right sides are opposed to the locked holes 18 on the column members 9a and 9b side. As described above, the cylinder 61 of the driving means 55 is operated, and as shown in FIG. 7A, the pair of front and rear pushers 54a and 54b are moved back and forth in synchronization with each other from the advanced position to the backward limit position. As a result, the operating levers 23a and 23b are released from the pushers 54a and 54b, and the operating levers 23a and 23b and the locking members 16a to 17b are moved back by the urging force of the compression coil springs 20 and 29, respectively. The locking members 16a to 17b projecting and moving from the left and right frame members 11a and 11b of 7b / 7c are fitted into the locked holes 18 on the column members 9a and 9b. . In this state, the elevating carriage 6 is lowered to move the shelf board support base 50 downward from the shelf board 7b / 7c, and the shelf board 7b / 7c is moved to the shelf board support frames 8a and 8b by the locking members 16a to 17b. With the side supported, the multistage telescopic moving body 51 is reduced and the shelf support 50 is returned to the home position on the lift carriage 6 to complete a series of height change operations for the shelves 7b / 7c. To do.

  In addition, when it is in the situation where the crane 1 for warehousing cannot be diverted to the mobile work vehicle for changing the height of the shelf board, the height changing work of the shelf boards 7b to 7n can also be performed manually. For example, when the height of the shelf board 7b / 7c is changed as described above, the workers standing on both the front and rear sides of the shelf board 7b / 7c are arranged on both sides of the shelf board 7b / 7c (front and rear side frame members). 10a, 10b) are supported by both hands, and the operation members 26 of the operation levers 23a, 23b are operated to be pulled toward the front with the fingertips of both hands of each operator, so that the locking members 16a-17b are moved to the support members 9a, The operation levers 23a and 23b are pulled toward the front and rear side frame members 10a and 10b by an operator who is retracted from the locked hole 18 of 9b and supports both front and rear sides of the shelf board 7b / 7c with both hands. The shelf boards 7b / 7c can be moved vertically up and down to a target level in the state. If the shelf board 7b / 7c is moved up and down to a target level, both the operating levers 23a and 23b can be operated with the locking members 16a to 17b facing the locked holes 18 on the column members 9a and 9b. The fingertips may be released and the locking members 16a to 17b may be protruded and fitted into the locked holes 18 on the support members 9a and 9b.

  Although the operation levers 23a and 23b that linearly move in the front-rear horizontal direction are used as the operation means 22, the upper side is pivotable back and forth around the left and right horizontal support shaft 37 as shown in FIG. The supported operating lever 38 can be used in place of the operating levers 23a and 23b. In this case, only the portion 38a supported by the support shaft 37 of the operation lever 38 is protruded upward from a belt-like lever body portion 38b that is long in the horizontal direction including the operation portion 26, and the upper protrusion portion 38a is formed as a roller rail. If supported by the support shaft 37 at a position near the upper surface of the peripheral frame 12 between 13, the swing radius of the operation lever 38 can be increased while suppressing the height of the peripheral frame 12. Reference numeral 39 denotes a bearing member that pivotally supports the operation lever 38 with the support shaft 37, and 40 denotes a spring that biases the operation lever 38 in a direction away from the front and rear frame members 10a and 10b.

  FIG. 11 shows another embodiment of interlocking means 24 and 25 for interlockingly connecting the operation levers 23a and 23b and the locking members 16a to 17b. In the interlocking means 24 and 25, both end portions of the operation levers 23a and 23b and the locking members 16a to 17b at positions close to both end portions of the operation levers 23a and 23b are respectively connected to the L-shaped links 41a, 41b and 42a, It is interlocked and connected by 42b. The bent portions of the L-shaped links 41a to 42b in the illustrated example are pivotally supported inside the front and rear side frame members 10a and 10b of the shelf peripheral frame 12 by the vertical support shaft 43, and on the operation levers 23a and 23b side. The link end portion 44 is fitted inside the end portions of the operation levers 23a and 23b and comes into contact with the inner surfaces of the operation levers 23a and 23b, and the link end portion 45 on the side of the locking members 16a to 17b is connected to this link. The long holes 46 on the end 45 side and the vertical pins 47 on the locking members 16a to 17b side are interlocked and connected. The operating strokes of both the operating levers 23a and 23b are the same, and the retracting strokes of the locking members 16a to 17b are also the same. Therefore, the locking members 16a to 16a on the same front and rear side as the operating levers 23a and 23b. When the link lengths of the L-shaped links 41a, 41b and 42a, 42b are changed in accordance with the distance in the front-rear direction between the control levers 17b and the operation levers 23a, 23b are pulled toward the front and rear side frame members 10a, 10b, The stop members 16a to 17b are configured to be retracted by a required distance to the left and right side frame members 11a and 11b side of the shelf board peripheral frame 12. In addition, although each latching member 16a-17b and each L-shaped link 41a-42b are directly linked and connected, another link can also be interposed between both as needed.

  The tip of each locking member 16a-17b, that is, the portion that fits into the locked hole 18 provided in the column members 9a, 9b of the shelf support frames 8a, 8b may have a round shaft shape. As shown in FIG. 12, a side-view inverted L shape in which a locking portion 48 projecting downward from the tip is continuously provided, and the locked hole 18 provided in the columnar members 9a and 9b having the hollow structure A long hole in the vertical direction can be formed so that the distal ends of the locking members 16a to 17b including the stopper 48 can move in and out in the horizontal direction. In this case, the distal end locking portions 48 of the locking members 16a to 17b have entered the hollow structure column members 9a and 9b below the elongated hole-shaped locked holes 18, so that the operation means remains as it is. Even if 22 is operated, the locking members 16a to 17b cannot be withdrawn from the locked holes 18. Therefore, when changing the height of the shelf plates 7b to 7n, the shelf plates 7b to 7n are supported to the shelf plate so that the tip ends of the locking members 16a to 17b abut against the upper ends of the elongated holes 18 to be locked. The operating means 22 is operated by the operating means driving device 53 (or manual work) while being lifted by the stand 50 (or manual work).

  In addition, although embodiment which applied this invention to the fluid shelf equipment provided with the crane 1 for warehousing was shown, this invention is the fluid shelf equipment without the crane for warehousing which can be diverted to the mobile work vehicle for shelf board height change, It can also be applied to general rack equipment in which shelves are installed horizontally. In this case, a dedicated mobile work vehicle having an up-and-down shelf board support base 50 equipped with an operation means driving device 53 that can be entered under the shelf boards 7b to 7n is used. At this time, if a mobile work vehicle that can be moved in the front-rear direction of the shelf boards 7b to 7n is used, there is no need to support the shelf support base 50 with the multistage telescopic moving body 51, and it is simply forward from the mobile work vehicle. It is only necessary to provide an elevating drive device (which may be manually operated) for raising and lowering the shelf support base 50 protruding in a cantilever manner. Further, in this case, it is desirable that the mobile work vehicle is provided with an anti-falling wheel that is positioned almost directly below the shelf support 50 that cantilevered forward from the mobile work vehicle.

  In the configuration of the present invention, in addition to the fluidized shelf equipment provided with the craving crane 1 shown in the embodiment, the warehousing work is manually performed (without the craving crane 1), and the shelf is horizontally provided. It can also be applied to general rack equipment to be installed.
