Description

  The present invention relates to a three-dimensional warehouse for efficiently storing a cylindrical member such as a coiled article such as a wire or a plate.

Conventionally, as a method for delivering a cylindrical member such as a coiled article such as a wire rod or a plate material to a storage part of a three-dimensional warehouse, the cylindrical member loaded on the slide fork is sandwiched by a stabilizer disposed above, and the cylindrical member falls. There is a stabilizer system to prevent this.
However, this method has a problem that the fall prevention is not reliable when the axial dimension is smaller than the radial dimension of the cylindrical member loaded on the slide fork.
In addition, in order to prevent the cylindrical member from falling and securely hold it, there is a hook system in which a C hook (or L-shaped hook) is inserted into the hollow portion of the cylindrical member and suspended and suspended. The hook must be swiveled according to the direction of the arm of the storage to be loaded. For this reason, the width of the passage for running the stacker crane is defined by the turning diameter of the cylindrical member suspended on the hook, and the arrangement interval of the storage portions opposed to each other across the passage is expanded, which is a three-dimensional warehouse compared to the stabilizer system. There was a problem that the loading efficiency of the was reduced.

Various studies have been made to solve the decrease in the loading efficiency in the hook method. For example, in (Patent Document 1), “a lifting platform that moves up and down along a pair of upright posts, a hook moving rail that is provided at a lower portion of the lifting platform and is orthogonal to the traveling direction of the stacker crane, Stacker crane in a three-dimensional automatic warehouse for storing a cylindrical object such as a wire coil, characterized by comprising a pair of left and right L-shaped hooks that are guided by the rail and can be taken in and out in opposite directions. Is disclosed.
In addition, (Patent Document 2) states that “a plurality of racks for storing coiled articles in multiple stages, a traveling carriage having a pair of masts provided between opposing racks, and a movable carriage between the masts are provided. In an elevator cage and a coiled article transfer device in a three-dimensional warehouse provided with a C hook on the elevator cage, a slide beam can be pivotally installed at the lower center of the elevator cage and the C hook can be moved forward and backward in the slide beam. And a fork portion of the C hook provided with a slide fork so as to be able to move back and forth.
Japanese Patent Laid-Open No. 7-17604 JP-A-5-58408

However, the above conventional technique has the following problems.
(1) (Patent Document 1) includes a pair of left and right L-shaped hooks that can be inserted and removed in opposite directions, so there is no need to pivot the L-shaped hooks and prevent a reduction in loading efficiency. However, when each L-shaped hook can only take in and out the cylindrical object only in one of the left and right directions, and when it is necessary to put in and out a large number of cylindrical objects in the same direction, It had the subject that work efficiency would fall easily.
(2) (Patent Document 2) The C hook is installed in the slide beam so that it can be moved forward and backward, and the slide fork is provided in the fork part of the C hook so as to be able to move forward and backward. Although the rack interval can be shortened, there has been a problem that it cannot be made smaller than the turning diameter defined by the axial dimension of the coiled article.

  The present invention has been made to solve the above problems, and can reliably carry and transfer work without causing a cylindrical member such as a wire coil to fall or toppling over, and has excellent reliability. The cylindrical member can be stored finely by effectively using the space provided, the width of the passage required for stacker crane travel can be minimized, and the stacking efficiency is excellent. It is an object of the present invention to provide a three-dimensional warehouse that can eliminate waste in the delivery operation and is excellent in the efficiency of carrying in and carrying out cylindrical members.

The delivery operation of the cylindrical member in the three-dimensional warehouse according to the first embodiment will be described.
FIG. 6A is an enlarged plan view of a main part showing the positional relationship between the storage unit and the stacker crane in the three-dimensional warehouse of the first embodiment, and FIG. 6B is a view of the cylindrical member in the three-dimensional warehouse of the first embodiment. It is a principal part fracture | rupture expansion side view which shows delivery operation | movement. For convenience of explanation, a part of the delivery mechanism is omitted.
First, the operation for storing a cylindrical member in a three-dimensional warehouse will be described.
In FIG. 6A, the width of the passage 2, that is, the interval W between the free ends of the arms 4 disposed opposite to the storage portions 3 a and 3 b is larger than the turning diameter D of the cylindrical member 30 suspended on the hook 21. It is formed narrow. Therefore, the turning motion of the hook 21 needs to be performed in the turning spaces 9a and 9b without the arm 4 shown in FIGS. First, after receiving the cylindrical member 30 from the member delivery portion 8a in the turning space 9a of FIG. 1, the necessity of the turning operation is determined according to the direction in which the cylindrical member 30 is loaded. That is, in FIG. 3, when the cylindrical member 30 is loaded on the arm 4 on the storage unit 3 b side, the turning operation by the turning mechanism 19 is not necessary, and when the cylindrical member 30 is loaded on the arm 4 on the storage unit 3 a side, the turning mechanism The turning operation by 19 is required. In addition, the cart (not shown) that carries the cylindrical member 30 into the member delivery portion 8a is retracted when the hook 21 turns, and does not interfere with the turning operation.
Next, as shown in FIG. 6A, the lifting platform 7 in which the cylindrical member 30 is suspended on the hook 21 is moved to the position of the arm 4 on which the cylindrical member 30 is loaded. Movement in the left-right direction is performed by causing the stacker crane 6 to travel along the passage 2, and movement in the up-down direction is performed by raising and lowering the lifting platform 7.
After the cylindrical member 30 is moved to the position of the target arm 4, the hook 21 is slid back and forth by the sliding mechanism 20 of the delivery mechanism 18 as shown in FIG. Thus, the cylindrical member 30 can be loaded on the arm 4.

Next, the operation when carrying out the cylindrical member stored in the three-dimensional warehouse will be described.
First, as shown in FIG. 6A, the lifting platform 7 is moved to the position of the arm 4 on which the cylindrical member 30 to be carried is loaded. As shown in FIG. 6B, the cylindrical member 30 can be suspended on the hook 19 by sliding the hook 21 back and forth by the sliding portion 20 of the delivery mechanism 18 and moving the lifting platform 7 up and down.
In addition, it is necessary to turn the hook 21 in the direction of the arm 4 on which the cylindrical member 30 is loaded in advance, but when the cylindrical member 30 is not suspended on the hook 21, the hook 21 is loaded on the arm 4 or the arm 4. Further, since there is no interference with the other cylindrical member 30, the turning motion of the hook 21 can be performed at an arbitrary position on the passage 2. For this reason, since the lifting platform 7 that has finished the storing operation can be immediately moved to the position of the cylindrical member 30 to be carried out without moving to the swiveling spaces 9a and 9b, the carrying-out operation can be performed. Excellent practicality and workability.
Next, the lifting platform 7 with the cylindrical member 30 suspended on the hook 21 is moved to the swivel space 9b of FIG. 1, and the cylindrical member 30 is carried out from the member delivery portion 8b. At this time, the hook 21 is turned by the turning mechanism 19 as necessary. That is, when the cylindrical member 30 is received from the arm 4 on the storage unit 3b side, the turning operation is unnecessary, and when the cylindrical member 30 is received from the arm 4 on the storage unit 3a side, the turning operation is required. In addition, the cart (not shown) that carries the cylindrical member 30 out of the member delivery portion 8b is retracted during the turning operation of the hook 19, and does not interfere with the turning operation. The cylindrical member 30 can be received by entering the member delivery portion 8b after the end of the turning operation.

As described above, the three-dimensional warehouse according to Embodiment 1 has the following effects.
(1) Since the lifting platform 7 disposed on the stacker crane 6 includes the delivery mechanism 18 for delivering the cylindrical member 30, the stacker crane 6 is self-propelled along the passage 2, and the lifting platform By moving up and down 7, an arbitrary arm 4 can be selected from a plurality of arms 4 arranged at equal pitches in the vertical and horizontal directions in the storage portions 3a and 3b, and the cylindrical member 30 can be delivered.
(2) Since the hook 21 that is inserted through the hollow portion of the cylindrical member 30 and suspends the cylindrical member 30 is disposed in the delivery mechanism 18 of the lifting platform 7, regardless of the radial dimension or axial dimension of the cylindrical member 30. The cylindrical member 30 can be reliably held and can be prevented from dropping during conveyance.
(3) Since the delivery mechanism 18 of the lifting platform 7 has a turning mechanism 20 that turns the hook 19 in a horizontal plane in accordance with the delivery direction of the cylindrical member 30, it is opposed to the passage 2 where the stacker crane 6 is self-propelled. The cylindrical member 30 can be efficiently delivered by selecting one of the storage units 3a and 3b.
(4) Since the delivery mechanism 18 of the lifting platform 7 has the sliding mechanism 19 that moves the hook 19 back and forth in parallel with the longitudinal direction of the arm 4, the lifting and lowering motion of the lifting platform 6 and the forward and backward movement of the hook 21 cause the hook 21. The cylindrical member 30 can be simply delivered between the arm 4 and the arm 4.

Left and right spacing adjustment portion 22a, a guide portion of the left and right spacing adjustment portion 22 formed in a concave shape, 22b is a sliding portion of the left and right spacing adjustment portion 22 connected to the upper portion of the mounting portion 18a of the delivery mechanism 18, 22c is a guide roller that is rotatably disposed on the side of the sliding portion 22b and is loosely fitted to the guide portion 22a. 22d is a top plate portion 15f that is connected to the end of the sliding portion 22b and is expanded and contracted. This is a piston cylinder of the left-right distance adjusting unit 22 that slides the entire delivery mechanism 18 left and right.

Since the two sets of delivery mechanisms 18 and 18 have the turning mechanism 19, the sliding mechanism 20, and the hook 21, respectively, the turning of the hook 21 and the delivery of the cylindrical member 30 can be performed independently. Thereby, when only one cylindrical member 30 is accommodated in the lifting platform 7a, when the delivery locations of the two cylindrical members 30 are separated, the delivery directions of the two cylindrical members 30 are different, and so on. It can be used and has excellent versatility.
Also, the left-right distance adjusting unit 22 is disposed at two locations inside the top plate portion 15f disposed on the upper portion 15d of the frame portion 15 of the lifting platform 7a, and the two sets of delivery mechanisms 18 and 18 are respectively connected to the lifting platform 7a. On the other hand, it is slidably held in the left-right direction. Thereby, since the space | interval of the left-right direction of two sets of delivery mechanisms 18 and 18 can be changed, before turning operation | movement of the hook 21, two sets of delivery mechanisms 18 and 18 are matched with the turning diameter D of the cylindrical member 30. It is possible to widen the interval and prevent interference between the cylindrical members 30 during the turning operation. After the turning operation, the cylindrical member 30 can be reliably delivered by adjusting the distance between the hooks 21 and 21 in accordance with the pitch P in the left-right direction of the arms 4 of the storage portions 3a and 3b.

The mechanism of the left-right distance adjusting unit 22 is not limited to the present embodiment, and any mechanism that can slide the delivery mechanism 18 may be used. The ridges and ridges provided at the upper end of the delivery mechanism 18 are loosely fitted to the ridges and ridges provided in the left and right direction on the top plate portion 15f of the frame portion 15 of the lifting platform 7a, A guide shaft provided on the table 7a can be used such that the upper end of the delivery mechanism 18 is slidably inserted and slid.
In the present embodiment, the two sets of delivery mechanisms 18 and 18 are slidably held by the left and right spacing adjustment units 22 and 22, respectively, but the distance between the two sets of delivery mechanisms 18 and 18 may be adjusted. Alternatively, only one of them may be slid by the left-right distance adjusting unit 22 while one of them is fixed.

The delivery operation of the cylindrical member in the three-dimensional warehouse according to the second embodiment will be described.
First, the operation for storing a cylindrical member in a three-dimensional warehouse will be described.
After receiving the two cylindrical members 30 from the member delivery portion 8a in the turning space 9a of FIG. 1, the necessity of the turning operation is determined according to the direction in which the two cylindrical members 30 are loaded. That is, when the two cylindrical members 30 are loaded on the arm 4 on the storage unit 3a side, no turning operation is required, and at least one of the two cylindrical members 30 is loaded on the arm 4 on the storage unit 3b side. In this case, a turning operation is required.
In order to deliver the cylindrical member 30 to two adjacent arms 4, as shown in FIG. 7, the distance between the two sets of delivery mechanisms 18, 18 in the left-right direction is the left and right of the arms 4 of the storage portions 3 a, 3 b. Must be equal to the direction pitch P. However, when the pitch P in the left-right direction of the arm 4 is formed to be narrower than the turning diameter D of the cylindrical member 30 suspended from the hook 19, the cylindrical member suspended from the left and right hooks 21, 21 as it is. The 30s interfere with each other and cannot turn. Therefore, before performing the turning operation, as shown in FIG. 8, the two sets of delivery mechanisms 18, 18 are arranged so that the distance between the left and right hooks 21, 21 is wider than the turning diameter D by the left / right distance adjustment units 22, 22. Slide left and right.

Next, the hook 21 on which the cylindrical member 30 loaded on the arm 4 on the storage unit 3b side is suspended is swung in the swiveling space 9a. After the turning operation is finished, the left and right interval adjustment units 22 and 22 again adjust the left and right intervals of the two delivery mechanisms 18 and 18 to the left and right pitch P of the arms 4 of the storage units 3a and 3b.
After moving the lifting platform 7a to the position of the target arm 4, as shown in FIG. 9, the hook 21 is slid back and forth by the sliding mechanism 20 of each delivery mechanism 18, and the lifting platform 7a is moved up and down. Thus, each cylindrical member 30 can be loaded on the arm 4 of the storage portions 3a and 3b.

Next, the operation when carrying out the cylindrical member stored in the three-dimensional warehouse will be described.
First, the lifting platform 7a is moved to the position of the arm 4 on which the cylindrical member 30 to be carried is loaded, and the hook 21 is slid back and forth by the sliding mechanism 20 of each delivery mechanism 18 as shown in FIG. The two cylindrical members 30 can be suspended from the respective hooks 21 by raising and lowering the lifting platform 7a.
Next, the elevating platform 7a in which the cylindrical member 30 is suspended on each hook 21 is moved to the swivel space 9b in FIG. 1, and the cylindrical member 30 is carried out from the member delivery portion 8b. At this time, the hook 21 is turned as necessary. That is, the hook 21 that receives the cylindrical member 30 from the arm 4 on the storage unit 3a side does not need to perform a turning operation, and the hook 21 that receives the cylindrical member 30 from the arm 4 on the storage unit 3b side requires a turning operation. When performing the turning operation, as shown in FIG. 8, the two sets of delivery mechanisms 18, once so that the distance between the left and right hooks 21, 21 is made larger than the turning diameter D by the left / right distance adjustment units 22, 22. 18 is slid in the left-right direction. After the turning operation is finished, the distance between the two sets of delivery mechanisms 18 and 18 in the left-right direction is adjusted in accordance with the pitch of the arm on the side of the carriage (not shown) carrying out the cylindrical member 30. The carriage can enter the member delivery portion 8b after the turning operation is completed, and can receive the cylindrical member 30.

Since the three-dimensional warehouse according to the second embodiment is configured as described above, it has the following actions in addition to the actions of the first embodiment.
(1) Since the two sets of delivery mechanisms 18 and 18 are arranged side by side on the lifting platform 7a, the two cylindrical members 30 can be accommodated in one lifting platform 7a to perform the transfer work, and work efficiency is improved. Can be improved.
(2) Since the two sets of delivery mechanisms 18 and 18 each have the turning mechanism 19, the sliding mechanism 20, and the hook 21, the turning of the hook 21 and the delivery of the cylindrical member 30 can be performed independently. Therefore, when only one cylindrical member 30 is accommodated in the lifting platform 7a, or when the delivery locations of the two cylindrical members 30 are separated, it is possible to cope with cases where the delivery directions of the two cylindrical members 30 are different. Excellent in properties.
(3) Since the elevating platform 7a has the left / right distance adjusting unit 22 that changes the distance between the two pairs of delivery mechanisms 18, 18, the left / right hooks are adjusted to the left / right pitch P of the arms 4 of the storage units 3a, 3b. Since the interval of 21 can be adjusted, the cylindrical member 30 can be reliably delivered even when the pitch P in the left-right direction of the arm 4 varies depending on the location.
(4) Since the elevating platform 7a has the left / right distance adjusting unit 22, the distance between the two delivery mechanisms 18 and 18 is increased according to the turning diameter D of the cylindrical member 30 when the hook 21 is turned. And the interval between the two delivery mechanisms 18, 18 can be reduced in accordance with the pitch P in the horizontal direction of the arm 4 during the delivery operation of the cylindrical member 30 with the storage portions 3a, 3b. The pitch P in the left-right direction of the arms 4 in the storage portions 3a and 3b can be formed narrower than the turning diameter D of the cylindrical member 30 suspended on the hook 21, and the loading efficiency of the storage portions 3a and 3b can be improved. Decline can be prevented.
