Description

  The present invention relates to an automatic warehouse hangar.

  The automatic warehouse hangar generally adopts a flat shelf system in which the entire lower surface of the load is directly placed on each shelf. In the flat shelf system, the loads such as cardboard boxes and wooden boxes are stored in each shelf as they are. It can also store loads with different widths and depths.

In conventional automatic warehouses, the hangar is generally a one-way type in which loads can be taken in and out only from one side (front side), and two hangars placed opposite each other and the transfer formed between these two hangars One unit of the automatic warehouse is constituted by the transfer device that travels along the passage. The shelf board is supported at its front edge (front edge side edge) by a horizontal beam-shaped front frame, and at its rear edge (back side edge) by a horizontal beam-shaped rear frame. And the site | part between the support | pillars provided in the both ends of each frame is comprised in one unit storage area (for example, refer patent document 1).
JP 2000-118631 A

  In the one-way type hangar described above, an additional hangar has been used to increase the amount of storage. However, since a large number of shelves and frames are used even in a one-way type hangar, simply adding more parts increases the number of parts by the number of expansions, which has been a growing demand for cost reductions in recent years. There was a problem that it was not appropriate.

  On the other hand, it can be considered to be a two-way type hangar in which two unit storage areas (shelves) are arranged back to back in plan view. In this two-way type hangar, the number of struts and frames constituting the two unit storage areas can be shared and reduced, so that the cost can be reduced compared to the addition of the one-way type hangar.

  However, in this case, in order to reduce the number of parts, the shelf board is formed in a substantially rectangular shape in plan view extending in the depth direction across both unit storage areas, and has a length more than twice that of the above-described one-way type shelf board. Become. For this reason, when a load is placed only on one storage area, or when a load is placed across the shelves, the shelves may be bent or deformed, causing a gap between adjacent shelves or shelves. A step is easily formed between the frame and the frame, and as a result, there is a risk of troubles such as catching the load on the step when loading and unloading.

  Therefore, the present invention has a technical problem to improve such a current situation.

  In order to solve this technical problem, the hangar of the automatic warehouse according to the invention of claim 1 is appropriately spaced along the direction in which the transfer passage extends between two transfer passages extending in parallel in a plan view. Are arranged in two rows in plan view, and the column groups in each row are connected by a beam-like frame extending horizontally, and two frames facing each other in the longitudinal direction of the frame. A plurality of arranged shelf boards are supported, and an area defined by four columns positioned at both ends of the two opposed frames is loaded by a transfer device that travels on the transfer passages on both sides thereof. The storage unit is configured as a storage unit in which unit storage areas are placed back-to-back, and a plurality of loads can be placed in the unit storage area in a state of being aligned in the frontage direction. Shelf groups between adjacent shelves It is that comprises a connecting means for retaining the one plate while allowing the rides are across.

  According to a second aspect of the present invention, in the hangar of the automatic warehouse according to the first aspect, the connecting means is a beam member extending across a shelf group constituting each of the storage units, and the shelf group is back-to-back. The beam member is also used as a stopper for regulating the depth position of the load by connecting with the beam member at the innermost part of the unit storage area located at the position.

  The hangar of the automatic warehouse according to the invention of claim 3 is a group of a plurality of struts which are erected between the two transfer passages extending in parallel in a plan view at appropriate intervals along the direction in which the transfer passage extends. Are arranged in two rows in plan view, and a plurality of shelves arranged in the longitudinal direction of the frame by two opposite frames are connected to each other by a beam-like frame extending horizontally. A unit storage area that supports and supports loading and unloading of the area defined by the four struts positioned at both ends of the two opposing frames by a transfer device that runs on the transfer passages on both sides of the frame is back-to-back No storage unit arranged, a unit storage area is a storage that can be placed in a state in which a plurality of loads are arranged in the frontage direction, and a shelf is attached to the frame and each shelf Fitting and engaging by dropping from above And impossible escape upwards the shelf plates is that are provided engaging means for lateral displacement impossible held.

  If comprised like Claim 1, since the shelf group of each storage unit will be integrally couple | bonded by a connection means, and it will be in the state like a single plate, the upper surface of the said shelf group can be made flush. it can. Moreover, even if the load is placed only in one unit storage area or is placed between adjacent shelf boards, the shelf board group is integrally coupled by the connecting means. The shelf board hardly jumps (floats).

  Therefore, regardless of the presence or absence of a load, it is possible to reliably prevent a step from being formed between adjacent shelves, and as a result, troubles such as catching a load on the step when loading and unloading can be prevented. There is an effect that it can be remarkably suppressed.

  Further, since the beam member for connection reinforcement also serves as a stopper member (a partition member for the shelf) for the load, it is not necessary to provide a separate stopper member, so that the member can be provided by this amount. There is an effect that the structure can be simplified by reducing the number of points.

  Further, according to the configuration of claim 3, the engaging means that fits and engages the frame and each shelf board by dropping the shelf board from above to hold the shelf boards so that they cannot be pulled upward and cannot be laterally displaced. Even if the load is placed only on one unit storage area or is placed between adjacent shelf boards, there is a step between the frame and each shelf board. Can be reliably prevented. As a result, when loading / unloading, the occurrence of troubles such as hooking the load on the step is reduced, and the loading / unloading is smooth.

FIG. 9 is a sectional view showing the relationship between the end shelf board, the rail and the support frame, and FIG. 10 supports the bent part on the rear side of the end shelf board. It is sectional drawing which shows a structure.

  First, an outline of an automatic warehouse will be described with reference to FIGS. 1 and 2.

  The automatic warehouse includes a group of storages 1a and 1b composed of multi-stage shelves 4a and 4b, a transfer passage 9 positioned between the storages 1a and 1b, and a loading / unloading unit 2 disposed outside the storages 1a and 1b. I have. In the automatic warehouse of the embodiment, a large number of hangars 1a and 1b are arranged in parallel in a plan view. The groups of hangars 1a and 1b are a group of two end hangars 1b located at both ends of the automatic warehouse, and an intermediate hangar 1 located between the end hangars 1b (corresponding to the hangar described in the claims). It is comprised by.

  The end hangar 1b is a one-way type in which the load W can be taken in and out only from one side. The end hangar 1b includes a group of front columns 5 that are provided at appropriate intervals along a direction Y (frontage direction) in which the transfer passage 9 extends at a location near the transfer passage 9, and on the side opposite to the passage 6. And a group of rear struts 6 erected at appropriate intervals along the frontage direction Y. In the group of front columns 5 arranged in a line, horizontal beam-like rails 7 as frames are mounted in multiple stages. A horizontal beam-like rear frame 73 is mounted in a vertical and multistage manner on the group of rear columns 6 arranged in a line. Between the rail 7 and the rear frame 73 facing each other, a plurality of end shelf boards 71 are juxtaposed in the frontage direction Y. Therefore, each end shelf 71 is supported by the rail 7 and the rear frame 73.

  The intermediate hangar 1a is a two-way type in which two unit storage areas (shelves) are arranged back to back in a plan view to form one storage unit. Transfer passages 9 are provided on both sides thereof. In the intermediate hangar 1a, a group of front columns 5 that are erected along the transfer passage 9 at appropriate intervals are arranged in two rows in plan view. Rails 7 are mounted on the group of front columns 5 in parallel and in multiple stages. A plurality of intermediate shelves 31 (corresponding to shelves described in the claims) are juxtaposed between the facing rails 7 in the frontage direction Y. Accordingly, each intermediate shelf 31 is supported by a pair of rails 7 extending in parallel. The upper surface of both the intermediate shelf 31 and the end shelf 71 is set to the same height as the rail 7.

  A self-propelled carriage 8 serving as a transfer device is placed on a pair of rails 7 facing each other at the same stage (the same height) so as to be able to travel along the pair of rails 7.

  The loading / unloading unit 2 includes a reservoir 11 provided in a state extending from the shelves 4 a and 4 b of each stage, and a pair of lift conveyors 12 that can be moved up and down along the mast 13. The lift conveyors 12 are arranged in a straight line in series with the reservoir 11 in plan view. In addition, in the vicinity of the loading / unloading unit 2, a loading / unloading transport conveyor 14 that is arranged in series with each lift conveyor 12 in plan view is provided.

  In this case, automatic loading and unloading is performed by changing the load W between the transfer conveyor 14 and the lift conveyor 12, the lift conveyor 12 and the reservoir 11, and the reservoir 11 and the self-propelled carriage 8. In addition, the conveyance conveyor 14 may be provided in multiple stages (refer to the one-dot chain line state in FIG. 1), and the function may be shared only for carry-in or for carry-out.

  Next, the structure of the self-propelled carriage will be described with reference to FIG.

  The self-propelled carriage 8 includes a main body frame 21 having a substantially rectangular shape in plan view, made of mold steel or the like, a pair of front and rear wheels 22, and a drive motor 23 capable of rotating forward and reverse to drive one wheel 22. The self-propelled carriage 8 is configured to be able to travel along the rail pair 7 by rotating one of the wheels 22 forward and backward with the drive motor 23.

  The self-propelled carriage 8 is provided with a placing plate 24 for placing the load W thereon. A pair of picking devices 25 extending in the depth direction X intersecting the frontage direction Y is provided on both sides of the mounting plate 24.

  Each picking device 25 includes a double-acting movable arm 26 that can move forward and backward toward the shelves 4a and 4b. Pickers 27 for pushing and pulling the load W are attached to both ends of the movable arm 26 so as to be horizontally rotatable.

  The movable arm 26 and the picker 27 in both the picking devices 25 are configured to be driven in conjunction by a driving means (not shown) such as a motor or an electromagnetic solenoid. The picker 27 is protruded laterally with the movable arm 26 greatly advanced, and then the movable arm 26 is retracted and the load W is drawn by the picker 27, whereby the load W is transferred from the shelves 4a and 4b to the self-propelled carriage 8. Can be replaced. On the contrary, the picker 27 is protruded sideways with the load W placed on the self-propelled carriage 8, and then the movable arm 26 is advanced to push the load W with the picker 27. It is transferred to the shelves 4a and 4b.

  The transfer mechanism of the load W is not limited to the illustrated one, and various types can be adopted.

  Next, the structure of the shelf 4a in the intermediate hangar 1a will be described with reference to FIGS.

  In each shelf 4a of the intermediate hangar 1a, an area defined by four front columns 5 positioned at both ends of a pair of opposing rails 7 is configured as a storage unit. A load W can be taken into and out of the storage unit from both transfer passages 9 side by an automatic carriage 8 traveling on both sides of the storage unit. Further, a plurality of loads W can be stored in each unit storage area of the storage unit in a state of being aligned in the frontage direction Y.

  As described above, between the opposing rails 7 of the shelves 4a of each step, a plurality of intermediate shelf plates 31 that are substantially rectangular in plan view and that are long in the depth direction X are arranged side by side in the frontage direction Y. Each intermediate shelf 31 is made of a metal plate formed in a shallow box shape with a downward opening. A bent portion 32 having a substantially L-shaped cross section is formed to be bent downward at both side edges on the front end side of the intermediate shelf 31. An insertion piece 33 is formed at a location near both ends of each bent portion 32 and formed in a downward convex shape by cutting out the periphery. The insertion piece 33 is formed with a locking hole 34 penetrating in the depth direction X. In addition, the both-sides edge part extended in the depth direction X among the intermediate shelf boards 31 is formed in cross-sectional U shape for reinforcement.

  On the other hand, each rail 7 that supports the side edge portion of the front side of the intermediate shelf 31 is formed in a generally downward-opening bowl shape. At both ends of the rail 7, brackets 41 having a substantially L shape in plan view, which overlap with the outer peripheral surface of the front column 5, are fixed by welding or the like. The rail 7 is fixed to the front surface of the adjacent front column 5 with a bolt or the like via a bracket 41. Accordingly, the rails 7 of each shelf 4a are connected in series by the number of storage units of the corresponding shelf.

  On the side surface of the rail 7 that is in contact with the intermediate shelf 31, a fitting in the shape of a handle in a plan view that protrudes toward the intermediate shelf 31 at a position corresponding to the insertion piece 33 formed in the bent portion 32 of the intermediate shelf 31. A plurality of joining pieces 42 are formed (10 in the embodiment). As shown in FIGS. 5, 6, and 8, by inserting the insertion piece 33 on the intermediate shelf 31 side from above into the insertion hole 43 formed in the fitting piece 42 in a vertically penetrating manner, The shelf 31 is held in a state in which it cannot be laterally displaced.

  Dowels 44 projecting obliquely forward toward the intermediate shelf 31 are formed by cutting and raising at locations below the respective fitting pieces 42 in the rail 7. In this case, when the insertion piece 33 on the intermediate shelf 31 side is fitted into the insertion hole 43 of each fitting piece 42 from above, the dowel 44 is fitted and engaged with the lower end edge of the locking hole 34 in the insertion piece 33. The insertion piece 33 is held so that it cannot be pulled upward. The insertion piece 33 on the intermediate shelf 31 side, the fitting piece 42 on the rail 7 side, and the dowel 44 correspond to the engaging means described in the claims.

  When attaching the intermediate shelf 31, first, the intermediate shelf 31 is temporarily placed between the pair of opposed rails 7 by placing the bent portion 32 of the intermediate shelf 31 on the fitting piece 42 of the rail 7. Then, by sliding the intermediate shelf 31 along the frontage direction Y, a simple procedure is sufficient in which the insertion piece 33 on the intermediate shelf 31 is guided into the insertion hole 43 of the fitting piece 42 and dropped from above. Therefore, the intermediate shelf board 31 can be attached with one touch, and the labor of assembling the hangar 3 can be reduced.

  Further, since the upper surface of the intermediate shelf 31 is set to the same height as the rail 7 and the intermediate shelf 31 is held by the dowels 44 on the rail 7 side so that it cannot be pulled upward, the load W is stored in one unit. Even if it is placed only in the area or straddled between adjacent intermediate shelves 31, it is possible to reliably prevent a step from being formed between the intermediate shelf 31 and the rail 7. Can do. As a result, when loading / unloading the load W, troubles such as hooking the load W on the step are reduced, and the loading / unloading of the load W becomes smooth.

  As shown in FIG. 6, a hanger plug 51 having a pair of holding claws 52 protruding downward is provided at appropriate intervals in one of the pair of rails 7 on which the self-propelled carriage 8 travels. ing. A trolley rail 53 extending along the longitudinal direction (frontage direction Y) of the rail 7 is sandwiched and fixed between both the holding claws 52 of each hanger plug 51. The trolley rail 53 is a rod-shaped member in which an insulator 55 is coated on the surface of the conductor 54. In the fitting groove 56 formed on the lower surface of the insulator 55, the power feeding portion 29 of the collector 28 provided in the self-propelled carriage 8 located at the lower stage of the rail 7 is inserted. By bringing the power feeding unit 29 into contact with the conductor 54, electric power is supplied from the trolley rail 53 to the self-propelled carriage 8.

  As shown in FIGS. 1, 2, and 4, a plurality of intermediate shelf boards 31 in each storage area are connected to each other by a pair of beam members 61 as connection means extending across the group of intermediate shelf boards 31. Has been. In this case, by connecting the intermediate shelves 31 group at the innermost part of the unit storage area located back to back with both beam members 61, both beam members are also used as stoppers for regulating the depth position of the load W. ing.

  Each beam member 61 of the embodiment is formed in a substantially L-shaped cross section by a horizontal piece 62 that overlaps the upper surface of each intermediate shelf 31 and a standing piece 63 that extends upward from one longitudinal side edge of the horizontal piece 62. It is a thing. The upright piece 63 serves as a stopper that prevents the load W placed on the intermediate shelf 31 from shifting in the depth direction X. On the horizontal piece 62, a plurality of hook-like engagement claws 65 projecting downward are formed by jumping up and down at intervals corresponding to the width dimension in the opening direction Y of the intermediate shelf 31 (in the embodiment, 5). Pieces). A through hole 66 for screw insertion is formed at one end of the horizontal piece 62.

  On the other hand, two engagement holes 35 corresponding to the engagement claws 65 of the beam member 61 are formed on the upper surface of the intermediate shelf 31 approximately symmetrically in plan view across the longitudinal center line A along the depth direction X. (4 locations in total, see FIG. 4). A screw hole 36 corresponding to the through-hole 66 of the beam member 61 is formed on the upper surface of the intermediate shelf 31 at a position closer to the left and right side edges than the engagement holes 35 with the longitudinal center line A interposed therebetween. It is formed in two substantially symmetrical shapes (4 locations in total, see FIG. 4).

  The reason why the engagement holes 35 and the screw holes 36 are provided on the upper surface of the intermediate shelf 31 so as to be substantially symmetrical in plan view with the longitudinal center line A in between is to make the intermediate shelf 31 common. . Thereby, it is not necessary to change the direction of the opening direction X of the intermediate shelf 31 in accordance with the beam member 61, and also in this respect, the labor of assembling the hangar 3 is reduced.

  When connecting the beam member 61 and each intermediate shelf 31, first, the engaging claw 65 of the horizontal piece 62 is engaged with the engaging hole 35 of each intermediate shelf 31 so that the standing piece 63 is positioned on the rail 7 side. The beam member 61 is superposed on each intermediate shelf 31 by being inserted into the intermediate shelf 31. Next, in this state, the beam member 61 is slid in the protruding direction (frontage direction Y) of the engaging claw 65, so that the engaging claw 65 abuts on the inner peripheral edge of the engaging hole 35 and the through hole of the horizontal piece 62. 66 and the screw hole 36 of the intermediate shelf 31 located at the end portion in the juxtaposed direction (frontage direction Y) are matched with each other, and then the mounting screw 67 (see FIG. 4) is inserted into the screw hole 36 through the through hole 66. ) From above.

  If comprised in this way, since the intermediate | middle shelf board 31 group of each storage unit will be integrally couple | bonded by the both beam members 61, and will be in the state like a single plate, the upper surface of the intermediate shelf board 31 group will be made flush. (There is no step between the adjacent intermediate shelves 31). Further, even if the load W is placed only in one unit storage area or is placed between adjacent intermediate shelf boards 31, the intermediate shelf board 31 group is integrated by the both beam members 61. Since they are coupled, the intermediate shelf 31 hardly jumps (floats).

  Therefore, it is possible to reliably prevent a step from being formed between the adjacent intermediate shelf plates 31 regardless of the presence or absence of the load W. As a result, the load is hooked on the step when loading / unloading the load. The occurrence of trouble can be remarkably suppressed.

  In addition, since the intermediate shelf 31 group and the beam members 61 are reinforced with each other to form a sturdy structure as a whole, the intermediate shelf 31 group long in the depth direction X does not have to be excessively thick (stiffness). Sufficient strength is ensured, and its deformation and backlash can be prevented or significantly suppressed. In this respect, the effect of preventing the intermediate shelf 31 from being lifted can be further exhibited.

  Next, the structure of the shelf 4b in the end hangar 1b will be described mainly with reference to FIGS.

  In each shelf 4b of the end storage 1b, a portion between the columns 5 and 6 adjacent to each other along the transfer passage 9 is configured as a unit storage area. A plurality of loads W can be stored in this unit storage area. The end shelf 71 arranged in parallel between the rails 7 facing each other among the shelves 4b of each step is also made of a metal plate formed in a shallow box shape with a downward opening, like the intermediate shelf 31 described above. Is. A bent portion 72 having a substantially L-shaped cross section is formed to be bent downward at the front and rear side edges extending in the frontage direction Y of the end shelf 71. In the end shelf 71, a pair of insertion pieces (not shown) are formed only at the front edge as in the case of the intermediate shelf 31. In addition, the both side edge part extended in the depth direction X among the edge part shelf boards 71 is formed in cross-sectional U shape for reinforcement.

  As shown in FIG. 9, the front edge of the end shelf 71 is supported by the rail 7. In this case, since the connection structure between the end shelf 71 and the rail 7 is the same as the relationship between the intermediate shelf 31 and the rail 7 described above, detailed description is omitted.

  The rear edge of the end shelf 71 is supported by a rear frame 73 made of a metal plate mounted in parallel with the rail 7 between the adjacent rear columns 6. The rear frame 73 is set to have substantially the same length as the rail 7. The rear frame 73 is fixed to the adjacent rear column 6 with bolts or the like via brackets 74 fixed to both ends.

  As shown in FIGS. 9 and 10, the rear frame 73 is formed with a forward opening groove 75 that opens toward the rail 7. A rear bent portion 72 of the end shelf 71 is inserted into the forward opening groove 75. At the upper end of the rear frame 73, a stopper piece 76 for preventing the load W from dropping is formed by bending downward.

  When the end shelf 71 is attached, the rear bent portion 72 of the end shelf 71 is inserted into the forward opening groove 75 of the rear frame 73 with the shelf 3 being slightly inclined, and then the end The end shelf 71 is temporarily placed between the rail 7 and the rear frame 73 by placing the front bent portion 72 of the shelf 71 on the fitting piece 42 of the rail 7. Next, by sliding the end shelf 71 along the frontage direction Y, a simple procedure of dropping the insertion piece on the end shelf 71 side into the insertion hole 43 of the fitting piece 42 is sufficient.

  Therefore, the end shelf 71 can also be attached in one touch. In addition, since the end shelf 71 is held by the dowels 44 and the rear frame 73 on the rail 7 side so as not to be able to be lifted upward, there is almost no possibility of the end shelf 71 jumping up (raising).

  The present invention is not limited to the above-described embodiment, and can be embodied in various forms. For example, the structure of the connecting means is not limited to the beam member described above, but can be engaged with an overlapping side edge portion of the adjacent intermediate shelf 31 by a one-touch operation such as fitting of the engaging claw and the engaging hole. It is also possible to provide a means to do this, or to fasten the overlapping side edge portions of adjacent intermediate shelf boards 31 with a fastener such as a bolt.

  The beam member is not limited to a substantially L-shaped cross section, and may be formed in various shapes such as a rod shape and a prism shape. There may be at least one beam member for each storage unit, and it may be arranged on the lower surface side of each shelf board. The beam member and the intermediate shelf board may be fastened with a plurality of bolts or the like.

  The engaging means is not limited to the above-described embodiment, and may be configured to be engaged by a one-touch operation such as fitting of the engaging claw and the engaging hole.

  In addition, the present invention can be applied to other types of automatic warehouses such as stacker crane type automatic warehouses and lift type mobile trolleys that only move up and down to transfer loads to shelves. .

  In addition, the configuration of each unit is not limited to the illustrated embodiment, and various modifications can be made without departing from the spirit of the present invention.
