Description

  The present invention relates to an inclined flow rack in which a plurality of carts arranged in a stacked manner are loaded with storage items in order from the top and sequentially pushed backward.

  2. Description of the Related Art Conventionally, a physical distribution storage facility called a cart-type tilted flow rack is well known. As shown in Patent Document 1, the inclined flow rack includes a rail-use storage shelf arranged along the front-rear direction, and a plurality of carriages attached to the storage shelf so as to run freely in the front-rear direction. I have. Furthermore, the length of the leg part which attaches a wheel differs for each trolley | bogie, and the trolley | bogie can arrange | position a several trolley | bogie in a laminated form. Then, by loading the storage items on the plurality of stacked carts in order from the top and sequentially pushing them backward, the plurality of carts loaded with the storage items are arranged side by side on the storage shelf in the front-rear direction. ing.

  Further, when unloading (unloading) the stored items on the carriage, the stored items are taken out in order from the front with respect to a plurality of carts arranged in the front-rear direction. During this unloading operation, when the stored items are taken out from the front row of carts, the second and subsequent carts loaded with the stored items travel forward by their own weight, and the second cart is at the front end position. It arrange | positions in a laminated form on the 1st trolley | bogie. In this way, each time the stored items are sequentially taken out from the front cart, the next cart is sequentially arranged in a stacked manner at the front end of the storage shelf.

  In such a slanted flow rack, when a stored item is taken out from the cart at the front end position during the unloading operation, any one of the carts arranged on the rear side is caused by dust or load on the rail (storage shelf). There is a case where the product does not slide due to fluctuation or the like and remains stopped at the back (rear position) of the storage shelf, and the warehousing operation cannot be performed smoothly.

  Therefore, in the inclined flow rack shown in Patent Document 2, hooks are provided upward at the rear end of the upper surface of the loading platform of each carriage, and engaged pieces are provided in a downward projecting manner at the front end of the lower surface. When the carts are arranged side by side in the front-rear direction, the hooks and the engaged pieces can be engaged between the adjacent carts. If one of these carts gets caught, the cart will run in conjunction with the other cart, eliminating the problem that the cart will remain stopped at the back. It can be done smoothly.

Patent No. 2507260 JP 2001-10705 A

  In the above-described slanted fluid rack, the stored items loaded on the pallet are loaded together with the pallet on the carriage, and the front end of the pallet is disposed so as to slightly protrude from the front of the carriage. . When pushing the cart loaded with stored items backward, the front end surface of the pallet on the loaded cart is loaded by the rear end surface of the pallet loaded with the stored items to be stored next. I push it back.

  However, in the conventional inclined type fluid rack shown in Patent Document 2, hooks and engaged pieces are attached to the upper surface and the lower surface of the carrier bed of the carriage, so that a plurality of carriages are stacked vertically. It is necessary to form a wide gap between the carts in the stacked state so that the hooks and the carrier do not interfere with each other between the carts. For this reason, when a cart loaded with stored items is pushed in by a pallet loaded with stored items to be stored next, the pallet sinks under the pallet on the loaded cart. Then, when the pallet (contained item) that has been submerged is delivered, if the pallet is lifted by a forklift, the pallet is caught, and the delivery operation may not be performed smoothly.

  If hooks or the like are not provided on the cargo bed of the carriage, the gap between the carriages in the stacked state can be narrowed, but when a plurality of carriages are arranged in the front-rear direction, the carriages cannot be connected. As described above, any of the carts may remain stopped at the back of the shelf, which may hinder the delivery operation.

  The present invention has been made in view of the above-mentioned problems, and the cart stops at the back of the shelf, or the pallet of the storage items to be stored next is below the pallet of the stored storage items.

  [2] The inclined flow rack according to item 1, wherein the widths of the cargo beds in the plurality of carts are set to the same size.

[3] In the plurality of carts in a stacked state, the width of the loading platform is gradually reduced as it is arranged on the upper side,
Among the carts that are adjacent to each other in the stacked state, the engagement piece of the upper carriage is arranged on the inner side so as not to overlap the engagement piece of the lower carriage in plan view. The inclined flow rack according to item 1 above.

  [4] The inclined flow rack according to any one of the preceding items 1 to 3, wherein the engagement piece is configured by a tip portion of an upward hook attached so as to protrude rearward with respect to the loading platform.

  According to the inclined flow rack of the invention [1], since the engagement piece and the engagement piece are attached to the side surface of the loading platform so as to protrude outward, the engagement piece and the engagement piece are stacked in a state where the carriages are stacked. It is possible to prevent the piece from interfering with the loading platform, and to narrow the gap between the carts in the stacked state. For this reason, it is possible to surely prevent a problem that the pallet of the storage item to be stored next enters into the lower side of the pallet of the stored storage item during the warehousing operation, and the warehousing operation can be performed efficiently and smoothly. it can.

  Furthermore, in the present invention, since the loading platform of each cart is arranged horizontally, it is possible to load the storage items on the cart in a stable state, to prevent problems such as collapse of the cargo, and to perform the loading and unloading work more smoothly. it can.

  In the state where a plurality of carts are arranged side by side in the front-rear direction, the carts are stopped at the back of the storage shelf because the front and rear carts can be connected by the engagement of the engaging pieces and the engaged pieces. Can be reliably prevented, and the delivery work can be performed efficiently and smoothly.

  According to the inclined type fluid rack of the invention [2], since the loading platform width of each carriage is formed to be the same, the stored items can be loaded under the same conditions on any carriage, and the loading and unloading work can be further performed. It can be done smoothly.

  According to the inclined flow rack of the invention [3], it is possible to prevent the engagement pieces from interfering with each other between adjacent carts, and to further narrow the interval between the carts in the stacked state. For this reason, it is possible to more reliably prevent a problem that the pallet of the stored item that is to be stored next enters the lower side of the pallet of the stored item that has been stored.

  According to the inclined flow rack of the invention [4], the carts arranged in the front-rear direction can be more reliably connected.

Each hook 62 is disposed upward, and the engagement piece 63 at the tip of each hook is disposed so as to protrude above the upper surface of the loading platform 30 to which the hook 61 is attached.

  In the present embodiment, the hooks 61 and 62 of the first to fourth carts 3 are arranged on the sides (outside) of the carts 30 in a plan view. Are not overlapped. That is, the hooks 61 and 62 (engagement piece 63) of the lower cart 3 among the carts 3 and 3 that are adjacent vertically in the stacked state do not overlap the loading platform 30 of the upper cart 3 in plan view. Are arranged on the outside.

  As shown by an imaginary line in FIG. 7B, an engaged piece 65 that can be engaged with the engaging piece 63 of the hook 61 of the first carriage 3 protrudes inward on the front leg 52 of the second carriage 3. Is provided. The engaged piece 65 is arranged so as to protrude sideways with respect to the loading platform 30 of the second carriage 3.

  As shown in FIG. 5, the front frame portion of each loading platform 30 of the third to fifth carts 3 is formed to project from both sides, and the lower end projects downward from the back side of each projecting portion. The plate-like engaged pieces 66 are fixed to each other. The engagement pieces 63 of the hooks 62 of the second to fourth carriages 3 can be engaged with the engaged pieces 66, respectively. Each of these engaged pieces 66 is disposed so as to protrude laterally with respect to the side surface of the loading platform 30 of each carriage 3.

  In the present embodiment, each of the engaged pieces 65 and 66 is arranged on the side (outside) with respect to the cargo bed 30 so as not to overlap in the plan view, like the hooks 61 and 62.

  In the above configuration, as shown in FIG. 3, in the state where the first to fifth carts 3 are arranged in the front-rear direction, the engaging pieces 63 and the engaged pieces corresponding to each other between the adjacent carts 3 and 3 are arranged. 65 and 66 can be engaged with each other.

  In addition, in this embodiment, although the structure of the hook 61 provided in the 1st trolley | bogie 3 and the hook 62 provided in the other 2nd-4th trolley | bogie 3 is different, it is not restricted only to it, In this invention The hook 61 of the first cart 3 may have the same configuration as the other hooks 62 of the second to fourth carts 4.

  Further, in the present embodiment, the engaged piece 65 of the second carriage 3 is provided on the front leg 52, but the present invention is not limited thereto, and in the present invention, the engaged piece 65 of the second carriage 3 is Similarly to the engaged pieces 66 of the third to fifth carts 3 other than that, it may be configured by plate-like members separately fixed to the front ends of both side portions of the cargo bed 30.

  In the inclined flow rack of the present embodiment configured as described above, the first (first) to the first end of the storage shelf (rail member 2) of the rack body 1 is stored in the first to first storage items (luggage) 7 in a state where the storage items (packages) 7 are not stored. The fifth carts 3 are arranged in this order in order from the bottom.

  When storing and storing the stored items 7 in the unstored flow rack, the stored items 7 are sequentially loaded from the top to the first to fifth carts 3 arranged in a stacked manner, and the carts 3 are pushed in sequentially. It is.

  That is, the first storage object 7 to be stored (first storage object) 7 loaded on the pallet 71 is lifted up together with the pallet 71 by a forklift, and through the front opening (carrying-in / out opening) of the rack body 1 in the inclined flow rack. It is placed on the loading platform 30 in the fifth cart 3 at the top.

  From this state, the next stored item (second stored item) 7 is to be loaded on the next fourth cart 3. In this case, the second stored item 7 is loaded onto the pallet 71. At the same time, the rear end surface (front end surface) of the pallet 71 of the second stored item 7 is lifted by a forklift, and the pallet 71 of the first stored item (loaded stored item) 7 loaded on the fifth carriage 3. The first stored item 7 is pushed rearward together with the fifth cart 3. Thus, when the fifth cart 3 is pushed in and travels backward, the upper portion of the fourth cart 3 is opened, and the second storage 7 is disposed above the fourth cart 3. Therefore, the second stored item 7 is lowered and placed on the loading platform 30 of the fourth carriage 3. Thereby, the warehousing operation of the second stored item 7 is completed.

  When the third and subsequent stored items 7 are stored after the second stored item is stored, the second stored items 7 are stored in the same manner as described above. That is, by pushing the pallet 71 of the storage 7 that has been stored the previous time with the pallet 71 of the storage 7 that is to be stored next, both the previous cart 3 and the previous cart 3 are moved backward. Push into. Thereafter, the stored item 7 to be stored next is placed on the loading platform 30 of the next cart 3.

  In this way, the first to fifth carts 3 are loaded while the stored items 7 are loaded on the respective carts 3 by sequentially pushing the stored items 7 into the fifth to first carts 3 in order from the top. Can be arranged side by side in this order from the front to the rear.

  In the inclined flow rack of the present embodiment, when the stored items 7 are further stored after loading the stored items 7 on all the carts 3, the pallet 71 of the last stored item 7 becomes the first one. The pallet 71 of the stored item 7 stored immediately before (fifth) is pushed backward together with the cart 3 and the first to fourth carts 3 before that. After the front end portion of the rail member (storage shelf) 2 is thus opened, the last stored item 7 is loaded on the front end portion of the rail member 2. Thereby, the warehousing work of all the stored items 7 is completed.

  Here, in the present embodiment, the hooks 61 and 62 and the engaged pieces 65 and 66 are attached to the sides of the respective loading platforms 30 so as not to overlap the loading platform 30 in a plan view. Compared with the case where hooks and engaged pieces are attached to the upper and lower surfaces of the carriage bed, the gap between the carriages 30 and 30 of the adjacent carriages 3 and 3 can be reduced in the state where the carriages 3 are stacked. The distance from the lower surface of the pallet 71 of the stored item 7 stored immediately before to the upper surface of the loading platform 30 of the cart 3 to be stored next can be reduced. That is, when the pallet 71 of the stored item 7 stored the previous time is pushed in by the pallet 71 of the stored item 7 to be stored next, the lower gap in the pallet 71 of the stored item 7 stored the previous time is set. Can be small. Therefore, it is possible to surely prevent a problem that the pallet 71 of the stored item 7 to be stored next sinks into the lower surface side of the pallet 71 stored one time before, and the warehouse operation can be performed efficiently and smoothly.

  Moreover, in this embodiment, since the front leg 52 of each carriage 3 arranged on the inclined rail 21 is longer than the rear leg 55 and the loading platform 30 of each carriage 3 is arranged horizontally, each carriage 3 Thus, the loading work of the stored items 7 can be performed more efficiently and smoothly. Furthermore, since the stored items 7 can be loaded on each carriage 3 in a stable state, problems such as collapse of the load can be reliably prevented, and the flow operation of each carriage 3 can be performed more smoothly, The stored item 7 can be stored and managed in a more stable state.

  On the other hand, in the inclined flow rack of the present embodiment, when the stored items 7 are carried out, the stored items 7 on the carts 3 arranged in front and rear are sequentially taken out one by one from the front.

  That is, the stored items 7 arranged in the foremost row and placed on the rail member 2 are taken out from the carry-in / out opening (front end opening) of the rack body 1 by a forklift. When the front row of stored items 7 is taken out in this way, the first to fifth carts 3 loaded with the stored items 7 travel on the rail 21 by their own weight and move forward, and the first cart 3 is the rail member 2. It is arranged in the uppermost front row (front end).

  Next, the stored item 7 placed on the first cart 3 is taken out. If it does so, the 2nd-5th trolley | bogie 3 will drive | work ahead on the rail 21 with dead weight, and the 2nd trolley | bogie 3 will be arrange | positioned in the lamination | stacking state on the 1st trolley | bogie 3 of the foremost row.

  Similarly, when the stored items 7 on each carriage 3 are sequentially taken out, the carriage 3 sequentially travels forward by its own weight. When all the stored items 7 are taken out in this way, the first to fifth carts 3 are arranged in a stacked state at the front end portion.

  Here, in the present embodiment, normally, when the stored item 7 is carried out at the time of unloading work, all the carts 3 arranged in a rearward direction travel together. In this case, even if any of the carts 3 is caught and stopped, the carts 3 and 3 adjacent to each other are connected by the hooks 61 and 62 and the engaged pieces 65 and 66. Therefore, since the cart 3 that has been caught travels following the other cart 3, it is possible to prevent such a problem that the cart 3 stops in the middle of the rail, and the delivery work can be efficiently and smoothly performed. It can be carried out.

  As shown in these drawings, the inclined flow rack of the second embodiment is substantially different from the inclined flow rack of the first embodiment in each of the first embodiments. While the width dimensions of the loading platform 30 of the carriage 3 are formed to be the same, and the hooks 62 of the loading platforms 30 are arranged at overlapping positions in plan view, in the second embodiment, each carriage 3 is a loading platform. The width dimension of 30 is formed so as to gradually become narrower as it is arranged upward, and the hooks 62 of the respective loading platforms 30 are arranged so as not to overlap in plan view.

  In other words, the inclined flow rack of the second embodiment includes three carts 3 that are the first cart 3, the second cart 3, and the third cart 33 in order from the bottom in a stacked state, and are carts adjacent to each other in the vertical direction. 3 and 3, the width dimension of the loading platform 30 of the upper cart 3 is formed narrower than the width dimension of the lower loading platform 30. That is, the width dimension of the loading platform 30 is sequentially reduced as it is arranged on the upper side.

Further, hooks 62 are fixed to the rear ends of both side surfaces of the loading platform 30 of the first and second carts 3 so as to extend rearward. Each hook 62 is arranged upward, and the engagement piece 63 at the tip of each hook is arranged so as to protrude above the loading surface of the loading platform 30 of the carriage 3 to which the hook 62 is fixed. In the state where the carriages 3 are stacked, the hooks 62 (engagement pieces 63) are arranged so as not to overlap each other between the first and second carriages 3 in plan view. 63) They do not interfere with each other. ,
Furthermore, each hook 62 is arrange | positioned outside the side surface of the loading platform 30 of each trolley | bogie 31 to which the said hook 62 is fixed similarly to the said 1st Embodiment.

  Engaged pieces 66 are fixed to the front ends of both side surfaces of the loading platform 30 of the second and third carriages 3 so as to protrude sideways. The engaged piece 66 is disposed so as not to protrude downward from the lower surface of the loading platform 30 of the carriage 3 to which the engaged piece 66 is fixed.

  In the second embodiment, the other configuration is substantially the same as the configuration of the first embodiment. Therefore, the same or corresponding parts are denoted by the same reference numerals, and redundant description is omitted.

  In the inclined flow rack of the second embodiment, when the third carriage 3 is pushed backward from the state where the carriages 3 are stacked, the engaged piece 66 of the third carriage 3 is brought into the hook 62 of the second carriage 2. It will be in the state which can be engaged.

  Further, when the second carriage 3 is pushed backward from that state, the hook 62 of the second carriage 3 passes through the inside of the hook 62 of the first carriage 2, and then the engaged state of the second carriage 3. The piece 66 becomes engageable with the hook 62 of the first carriage 3. In this way, the mutual hooks 62 of the first and second carriages 3 are prevented from interfering with each other.

  In the second embodiment, as in the first embodiment, the warehousing operation and the warehousing operation can be performed in the same procedure, and the same effect can be obtained.

  Furthermore, according to the inclined flow rack of the second embodiment, the hooks 62 and 62 and the engaged pieces 66 and 66 do not interfere with each other between the adjacent carts 3 and 3, so that they are adjacent in the vertical direction. In the carts 3 and 3, the dimension between the loading platforms 30 and 30 can be set to be even narrower. For this reason, when the pallet 71 of the previous storage unit (stored stored item) 7 is pushed in by the pallet 71 of the stored item 7 to be stored next, the next pallet 71 is set to 1 It is possible to more reliably prevent problems that may occur under the previous pallet 71 and further improve the workability during loading and unloading.

  In the above-described embodiment, the case where the number of carts is five or three has been described as an example. However, in the present invention, the number of carts is not particularly limited, and at least two or more carts are used. The present invention can be applied to any inclined type fluid rack provided with a carriage.

  The slanted fluid rack of the present invention can be used in a distribution storage facility for storing and managing stored items such as luggage.
