Description

  The present invention relates to a three-dimensional storage that stores a storage object such as a container in each storage unit.

When containers are loaded and unloaded in a container yard, generally, containers are stacked and placed.
However, in the case of stacking, for example, if the container loaded below is to be taken out first, it will be necessary to move the container loaded above to another place and take it out, resulting in poor work efficiency. There is.
As a solution to such a problem, there is proposed a type in which a container building having a large number of shelves is constructed and containers are placed on the shelves instead of stacking containers. . Examples of such formats include the following.

  On the container yard of the container terminal, container storage shelves are arranged in multiple rows and arranged in two rows and one set so as to form a container movement passage extending between the container storage shelves in the longitudinal direction of the container. A container storage building, an overhead crane mounted on the rail laid above the container storage building along the container storage building, and a suspension beam suspended from a trolley traversing the overhead crane, The hanging beam has a telescopic spreader with a twist gripping device for gripping the container at the four corners that hold the container and extend it to the left and right to deliver the container between the ground entrance and exit and each container storage shelf. A container storage device (see Patent Document 1).

On the other hand, when a container is transported by ship, the container storage building cannot be used, and therefore, the containers are placed on the ship in a state where the containers are stacked in upper and lower stages. In this case, it is necessary to connect the upper and lower containers so that the containers do not collapse when the ship shakes.
As a connection tool for connecting the containers to each other, there is known a connection-type connection tool generally called a full automatic system. This is done by manually attaching one end of the connector in advance to the stacking side, that is, the bottom of the container, and inserting the other end of the connector into the lower container to automatically lock the upper and lower containers. When the upper container is lifted, the locked state is released and the container can be automatically loaded or unloaded by a crane.

As an example of such a fully automatic twist type container connector, the following has been proposed.
In the connector main body provided with a positioning projection on the top and bottom, an insertion hole is provided through the end face of the projection, and an upper cone and a lower cone are provided on the upper and lower ends of the rotating shaft inserted into the insertion hole, An elastic member for pulling the rotating shaft back to the initial position is provided in the connector body, an inclined surface on one side of the lower projection, a protrusion on one or both ends of the diagonal position in plan view, and both sides A plurality of inclined surfaces are formed on the surface, and when loading or unloading to the lower container, each of the inclined surfaces and the protrusions abut against the engaging holes of the corner metal fittings of the lower container, A twist type container connector configured such that the lower cone rotates and is thereby engaged with and disengaged from the engagement hole (see Patent Document 2).

The connecting operation in the twist type container connecting tool will be outlined. In the state immediately before the connection, the center of the lower cone of the connector is slightly shifted from the center of the engagement hole of the corner metal fitting of the lower container, but the slope provided for laterally shifting the container in the lower direction of the lower cone. It is guided by the surface and moves slightly by the weight of the container. Then, when further lowered, the lower cone is guided by the diagonal protrusions of the lower cone and the inclined surface in plan view, and the lower cone contacts the engagement hole end surface of the corner metal fitting while rotating with respect to the connector body by a predetermined angle. When the lower cone is below the metal fitting of the engagement hole, the lower cone, the rotating shaft and the upper cone rotate together by the elastic member and return to the initial position. Engage with the hole.

In the container storage device described in Patent Document 1, the container is merely placed on the container storage shelf, and the container and the container storage shelf are not connected by a connector or the like. For this reason, when the container storage building is installed outdoors, if the container placed on the container storage shelf receives a strong wind, the container may deviate from the correct placement position of the container storage shelf, tilt, or fall down. Conceivable. Moreover, it is conceivable that the container is similarly displaced, tilted, or falls during an earthquake regardless of whether it is indoors or outdoors. If a part of the container protrudes from the traveling area of the trolley, for example, due to the displacement of the container, the traveling of the trolley is obstructed and the trolley cannot travel.
In addition, in order to automatically operate the trolley, it is common to grasp a predetermined portion of the container on the assumption that the container is in a predetermined position. It is also possible that it will not be possible.
In this way, when adopting the method of placing the container on the shelf, the container is connected to the shelf so that the container does not shift, tilt, or fall over from the correct position when the container is placed on the shelf. There is a need to.

Therefore, a means for connecting the container to the shelf is required, and as a means for connecting the container to the shelf, it is conceivable to use a container connecting tool for connecting containers introduced in “Background Art” of this specification.
However, when the fully automatic twist type container connector described in Patent Document 2 is applied to the connection between the container and the shelf, the following problems occur.

When the containers are connected to each other, as described in the outline of the connection operation, the upper containers to be stacked are slightly moved laterally while being guided by the inclined surface provided at the lower part of the lower cone. In the case of a wire suspension type in which the container to be placed is suspended by a wire or the like, this lateral movement is not particularly problematic because the movement is easily performed by twisting or shaking the wire.
However, when storing containers in a storage unit such as a container storage shelf, it is preferable to set the space of each container storage unit, for example, the height of the storage unit low, in order to increase the storage efficiency of the container. When the height is set low, it is difficult to lift the container with a wire or the like when the container is transferred.
For this reason, it is conceivable to transfer the container directly from the cart to the container mounting shelf. In this case, the container is transferred by being supported by a highly rigid supporting means such as a jack having a lifting cylinder. become. In this case, since the container cannot be moved during transfer, an excessive load acts on the jack side, which is not preferable.
Therefore, it is necessary to devise the support part of the container so that only the container can be moved a little at the time of loading and unloading. However, such a complicated support structure has a problem that it is expensive.

The problems to be solved by the present invention are summarized as follows.
Even when a container is supported by a rigid support means such as a lifting cylinder provided on a carriage and transferred, the container can be automatically connected to the shelf by transferring the container to the shelf of the storage unit. What should I do to make it?
Also, when taking out containers connected to shelves from the shelves, they can be supported by highly rigid support means like the lifting cylinders provided on the carriage and can be automatically disconnected and taken out. What should I do?
Even if the container placed on the shelf is automatically disconnected from the shelf and taken out, the container must be prevented from being disconnected when the container tilts or falls due to a strong wind or earthquake. How can we make this happen?
Such a problem is not limited to the case where the object to be stored is a container, but is also a problem to be solved for various stored objects.

  The present invention has been made to solve such a problem, and in a hangar for storing a storage object by placing it on a shelf, the storage object can be prevented from shifting, tilting, and falling, and the storage object is a cart. It is an object of the present invention to provide a three-dimensional hangar that can be applied to a load of a support system having a high rigidity such as being carried on a vehicle without increasing the cost.

(1) A three-dimensional hangar according to the present invention includes a storage unit that stores a storage object including a corner fitting having a rimmed engagement hole, and a stacker crane that moves up and down by placing the storage object on a lifting table. And a transfer shelf arranged on the lift table of the stacker crane and transferring the object to be stored between the lift table and each storage section. Provided with an engaging means for engaging the engaging hole of the corner fitting of the object to be stored in accordance with the mounting operation by the transferring means, and locking the object to be stored on the mounting shelf. The locking means has a pair of locking pieces to be locked to the corner metal fitting, and a base formed integrally with the pair of locking pieces, and the base is horizontal to the mounting shelf. It is characterized by being installed so as to be movable.

(2) Further, in the above described (1), the locking piece portion has a locking slope portion and a locking release slope portion, and the locking slope portion is used when the object to be stored descends. And the locking piece moves in the direction in which the locking piece engages with the corner metal fitting, and the slope for releasing the lock raises the object to be stored upward from the mounting shelf. In this case, it has a function of moving the locking means in a direction in which the locking piece portion and the corner metal fitting are released by contacting the corner metal fitting.
According to the invention of (2) above, when the object to be stored is lifted upward from the mounting shelf by the transfer means, the locking piece part and the corner metal fitting are released, but the container is damaged by the strong wind or earthquake. Even if a tilting or overturning force is applied, the engagement between the corner fitting and the engagement piece portion is not released. This point will be described below.
When a falling force is applied to the object to be stored due to wind, earthquake, etc., one side of the corner metal fittings will rise. At this time, the edge of the corner fitting pushes up the locking release slope of the locking piece, and generates a horizontal component force on the locking release slope of the locking piece. This horizontal component force tries to move the locking piece portion in the horizontal direction, but the remaining (opposite) locking piece portion of the pair of locking piece portions is pressed downward by the other corner fitting. Therefore, the locking piece portion cannot move in the horizontal direction, and the locking is not released even if a falling force is applied.

(3) Further, in the above-described (1) or (2), the locking piece portion can contact the corner metal fitting when the object to be stored is lowered, and the locking piece portion can be inserted into the corner metal fitting. It has a guide slope having a function of moving the locking means to a position.

(4) Moreover, in the thing in any one of said (1)-(3), the transfer means is equipped with the raising / lowering support means which can raise / lower the object to be stored, The raising / lowering table, each storage part, It is a cart that can move between the two.

(5) Moreover, in the thing in any one of said (1)-(4), the storing object is a container, It is characterized by the above-mentioned.

In the present invention, the storage object is provided on the mounting shelf of each storage unit, and is engaged with the engaging hole of the corner metal fitting of the storage object in accordance with the mounting operation by the transfer means. The locking means includes a pair of locking piece portions locked to the corner metal fitting, and a base portion formed integrally with the pair of locking piece portions, Since the base portion is installed on the shelf so as to be movable in the horizontal direction, the locking means moves in the horizontal direction as the storage object descends, and the locking piece locks the storage object. However, a large horizontal load does not act on the storage object side in the process of lowering the storage object.
Therefore, even if the object to be stored is a highly rigid support structure that is supported by the carriage, the transfer operation is possible, and it is not necessary to complicate the support structure.
In addition, since the pair of locking pieces are integrated by the base portion, the locking is not released even if a force that causes the container to fall down due to a strong wind, an earthquake, or the like is applied and it is safe.

FIG. 1 is a perspective view showing a part of a container hangar according to an embodiment of the present invention, and FIG. 2 is an explanatory view of a trolley for transferring a container in the container hangar, and the trolley is moved to a container storage section described later. Is shown.
The main part of the present invention lies in the structure of the container mounting shelf 29 in the container hangar. As a premise for explaining this, the overall structure of the container hangar will be outlined with reference to FIGS.

  The container hangar 1 according to the present embodiment is configured by a system similar to an automatic warehouse system using a stacker crane 3 as shown in FIGS. This system is provided with a multistage shelf type container storage 5 on both sides of a stacker crane 3 that can be moved up and down and horizontally, and moves the crane body 7 horizontally and moves the lifting table 9 on which the container 11 is placed. By doing so, the container 11 placed on the lifting table 9 can be positioned on the side of the predetermined container storage unit 5, and the container 11 can be transferred and stored in the container storage unit 5 (hereinafter simply referred to as “storage unit 5”). It is like that.

The container storage 5 and the lift table 9 are provided with rails 15 for moving the carriage 13 between them, and the container 11 is moved from the lift table 9 to the container storage 5 by moving the carriage 13 on the rail 15. Can be transferred to.
Positionable pins (not shown) for positioning the lifting table 9 accurately on the container storage unit 5 side are provided at the front, rear, left and right positions of the lifting table 9, and the positioning pins are provided at the bottom of the container storage unit 5. The lift table 9 can be positioned at a predetermined position by engaging with the upper surface or the like.

The carriage 13 is composed of a rectangular frame body, and wheels 21 are attached to frame members 19 on both sides thereof. A lift cylinder 23 is set on both side frame members 19 of the carriage 13, and a receiving seat 27 for supporting a transfer object is provided on each cylinder rod 25 of the lift cylinder 23.
Racks (not shown) are fixed to the side portions of both side frame members 19 of the carriage 13, while the lift table 9 is driven by a pinion (not shown) to be engaged with the rack at front, rear, left and right positions of the carriage 13. A motor is provided.

FIG. 3 shows the rear side 31 of the container placement shelf 29 in the container storage unit 5 (the side on which the short side on the back side of the container is placed when the container is placed. It is an explanatory view of a distant side portion), and shows a part of the container 11 to be placed. 4 is an enlarged view of a portion A surrounded by a circle in FIG. 3, and FIG. 5 is a cross-sectional view taken along line AA in FIG.
Hereinafter, the rear side portion 31 of the container placement shelf 29 and the container locking means 33 provided on the rear side portion 31 will be described with reference to FIGS.
A slide groove 35 extending in the width direction is formed in the rear side portion 31 of the container mounting shelf 29 as shown in FIGS. Then, the container locking means 33 that engages with the engagement hole 55 of the corner metal fitting 53 of the container 11 and locks the container 11 to the container mounting shelf 29 in accordance with the container mounting operation. It is slidable in the left-right direction in the figure.
Further, as shown in FIGS. 3 and 4, stopper pieces 34 projecting upward are provided at both ends of the rear side portion 31 of the container placement shelf 29. It has a function of preventing the container 11 placed on the placement shelf 29 from shifting and protruding from the container placement shelf 29. The stopper piece 34 is also provided at both ends of a front side (not shown) of the container placement shelf 29.

The container locking means 33 is inserted into the slide groove 35 while supporting the left and right locking piece portions 37 projecting upward from the slide groove 35 in a state where the container locking means 33 is installed in the slide groove 35. And a plate-like base 39.
The left and right locking pieces 37 have the same shape, and the interval between the two locking pieces 37 is set to the same width as the interval between the engagement holes 55 of the corner fittings 53 provided on both sides of the container 11. .
Hereinafter, the shape of the corner metal piece 53 and the shape of the locking piece portion 37 will be described.

As shown in FIG. 4, the corner fitting 53 has an engagement hole 55 having a width narrower than the width of the letter R at the lower part of the letter B having a vertical cross section. Since the width of the engaging hole 55 is narrower than the width of the square shape, the engaging hole 55 has a shape having edges on the left and right sides.
As shown in FIG. 4, the locking piece portion 37 is shaped like a sail of a triangular yacht with a pointed top 41. More specifically, the locking piece portion 37 includes a first inclined surface 43 (corresponding to a guide inclined surface portion of the present invention) inclined from the top portion 41 diagonally to the left in the drawing, and a lower end of the first inclined surface 43. A second inclined surface 45 (corresponding to the unlocking inclined surface portion of the present invention) that is formed continuously to the right and inclined obliquely downward to the right, and extends vertically downward continuously to the lower end of the second inclined surface 45. A first vertical surface 47, a second vertical surface 49 formed so as to extend vertically downward from the top portion 41, and a third slope formed continuously from the lower end side of the second vertical surface 49 and inclined obliquely downward to the right. A surface 51 (corresponding to the locking slope portion of the present invention). And the 2nd inclined surface 45 functions as a latching | locking part.
Further, the width W ₁ between the lower end and the second vertical surface 49 of the first inclined surface 43, the width W ₂ between the first vertical surface 47 and the lower end of the third inclined surface 51, but is set to the same, these It is set to be substantially equal to the width W ₃ of each engagement hole 55. However, the locking piece 37 because of the need to be inserted into the engaging hole 55 is set larger by a little than the width W _1, W ₂ is more wide W ₃ of the engaging hole 55.

The function of the first to third inclined surfaces 51 formed on the locking piece portion 37 will be described. When the container 11 is placed, the first inclined surface 43 abuts against the left edge lower portion 57 of the engagement hole 55 of the corner metal 53 and moves to a position where the locking means can be inserted into the engagement hole 55. It has a function to make it.
The third inclined surface 51 has a function of moving the locking means in the locking direction by contacting the right edge lower portion 59 of the engagement hole 55 in the drawing when the container 11 is placed.
When the container 11 is lifted, the second inclined surface 45 abuts on the upper left edge 61 of the engagement hole 55 in the drawing and has a function of moving the locking means in the locking release direction.

The outline of the container storing operation in the container storage 1 configured as described above will be described.
The container 11 is placed on the carriage 13 on the lifting table 9 via the seat 27 of the lifting cylinder 23, the crane body 7 is moved to a row where a predetermined container storage unit 5 is located, and the lifting table 9 is moved in that row. It is raised and lowered to the target storage unit 5 position.
In order to accurately position the elevating table 9 in the vertical direction with respect to the predetermined storage unit 5, a positioning pin is projected from the side of the table and engaged with the bottom of the storage unit 5.
In this state, the container 11 is lifted by the elevating cylinder 23 and the pinion is driven to move the carriage 13 in the direction of the storage unit 5. When the carriage 13 moves to the storage unit 5 side, the lifting cylinder 23 is driven to lower the container 11, and the lower surface thereof is placed on the placement unit in the storage unit 5.

The operation of the container locking means 33 when placing the container 11 will be described with reference to FIGS. In each of FIGS. 6 to 9, an enlarged view showing an enlarged A portion surrounded by a circle at the left end portion in the drawing is attached.
As shown in FIG. 6, the container 11 is supported by the carriage 13 and carried into the storage portion 5, and the top portion 41 of the locking piece portion 37 can be inserted into the engagement hole 55 of the corner fitting 53 of the container 11. Adjust the position as follows. In the state shown in FIG. 6, the right edge of the engagement hole 55 and the second vertical surface 49 are in contact with each other, and it is ideal that this positional relationship is satisfied. However, the top 41 of the locking piece 37 may be at a position where it can be inserted into the engagement hole 55. This is because if the top 41 of the locking piece 37 is in a position where it can be inserted into the engagement hole 55, the first inclined surface 43 and the lower edge on the right side of the engagement hole 55 in the drawing contact when the container 11 descends. When the container 11 is further lowered in this state, the entire locking means slides in the right direction in the drawing due to the action of the first inclined surface 43 so that the locking piece can be inserted into the engaging hole 55. It is.
When the container 11 is lowered in a state where the locking piece portion 37 can be inserted into the engagement hole 55, the head of the locking piece portion 37 is inserted into the engagement hole 55. FIG. 7 shows a state in which the head of the locking piece portion 37 is inserted into the engagement hole 55.

When the container 11 is further lowered from this state, the lower edge portion on the right side of the engagement hole 55 in the drawing contacts the third inclined surface 51 of the locking piece portion 37. When the container 11 is further lowered from the abutted state, the entire locking means moves in the left direction in the figure by pushing the third inclined surface 51 to the lower edge portion. When the entire locking means moves in the left direction in the figure, the second inclined surface 45 of the locking piece portion 37, that is, the locking portion is locked to the left edge of the corner metal 53 to bring the container 11 into a locked state. .
Thereafter, the carriage 13 is moved to the lifting table 9 side, and the transfer of the container 11 is completed.

  As described above, in the present embodiment, as the container 11 descends, the locking means side moves to the left and right to lock the container 11, so that in the course of the container descending operation, the container 11 side has a horizontal direction. Large load of does not work. Therefore, even if it is a support structure with high rigidity that the container 11 is supported by the carriage 13, the transfer operation is possible, and it is not necessary to make the support structure complicated.

Next, an operation when lifting the container 11 will be described.
When the container 11 is lifted straight up from the state shown in FIG. 9, the second inclined surface 45 of the locking piece 37 abuts on the left edge upper portion 61 of the engagement hole 55 as shown in FIG. 8. When the container 11 is further moved upward in this state, the entire locking means is moved rightward in the drawing by the action of the second inclined surface 45. Then, when the upper end portion of the second inclined surface 45 passes the edge of the locking hole, the locking is released and the locking piece portion 37 comes out of the engaging hole 55, and the container 11 moves upward.
As described above, when the container 11 is lifted, the container locking means 33 moves, so that the locking is automatically released, and an excessive load does not act on the container 11 at that time. Even if the support structure is so rigid that it is supported by the carriage 13, the container 11 can be lifted without complicating the support structure.

Further, as described above, when the container 11 is lifted straight up by the elevating cylinder 23, the lock is released. However, the lock is not released even if a force that tilts the container 11 due to strong wind or earthquake acts. This point will be described in detail below.
According to the inventor's research, there is almost no case where the force acting on the container 11 due to the influence of the wind or earthquake keeps the container 11 horizontal and lifts it straight up, and tries to tilt it with one side of the container 11 as a fulcrum. In most cases. Therefore, it is only necessary to prevent the lock from being released with respect to the force that tilts with one side of the container 11 as a fulcrum.
In this regard, in a state where the container 11 is locked, even if one side of the container 11 tries to float up due to a strong wind or an earthquake, and one of the locking pieces 37 is lifted upward by the corner fitting 53 of the container 11. Since the locking pieces 37 on both sides are integrated by the base 39, as long as the other locking piece 37 is pressed downward by the corner metal 53 of the container 11, the one locking piece is also Cannot move horizontally. Therefore, the locking piece portion 37 that is going to be pulled upward by the corner metal fitting 53 is not released, and the corner metal piece 53 does not come out of the hole.
In this way, even if the container 11 tries to rise due to the influence of strong wind, earthquake, or the like, it can be reliably prevented by the interaction of the pair of locking pieces 37 integrated.

  Further, in the above description, an example in which the container locking means 33 is provided on the rear side 31 of the container mounting shelf 29 is shown. However, this is because the container is tilted by strong winds and earthquakes on the long side of the container. The rear side 31 corresponds to the short side of the container 11 and is considered unlikely to be lifted at the same time, so there is a risk of being unlocked by strong winds and earthquakes. This is because it is almost the most preferable.

In the above description, the case where the object to be stored is a container has been described as an example. However, in the case of a container, a corner metal fitting having an engagement hole 55 is provided in the container itself. It is illustrated as an example, and the present invention is not limited to the case where the storage object is a container.
However, it is necessary for the storage object to be provided with the same metal fitting as the corner fitting of the container in order to lock the storage object with the transfer operation of the storage object and to release the lock. There is. An example of such is a pallet having a corner fitting similar to a corner fitting of a container.
Therefore, the present invention can also be applied to the case where the storage object is fixed and stored in such a pallet. That is, the storage object according to the present invention includes a container having a corner metal fitting like a container and various articles fixed to a pallet having the corner metal fitting.

In the above description, the example in which the container locking means 33 is provided on the rear side portion 31 of the container mounting shelf 29 is shown. However, the position where the container locking means 33 is provided is the front side of the container mounting shelf 29. It does not exclude parts and sides.
In addition, when providing the container locking means 33 in the front side part of the container mounting shelf 29, what is necessary is just to devise the cart 13 overcoming the container locking means 33. FIG.
