Description

  The present invention stores business warehouses that store deposited luggage, raw materials for manufacturing industries, factory warehouses that store products, warehouses in distribution and distribution centers, other warehouses, and storage areas that store luggage that arrives by land, shipping, air transportation, etc. The present invention relates to an on-site transfer / transfer apparatus and a storage rack facility of a warehouse facility that unloads and transports a package to / from a storage location and unloads and transports a package to / from the storage / storage location.

  The equipment that transports and arrives at the warehouse and storage location where packages are received and transported to the storage and storage location for loading, unloading and shipping to the storage and storage location. , Mainly with a forklift for loading floors, where the driver boarded and manually controlled the loading and unloading of the transport vehicle, and a transfer device with transfer means on the lifting platform, mainly automatically There are roughly two types of stacker cranes that can be stored in a three-dimensional shelf. Each has advantages and disadvantages, but both contribute to the distribution of goods with a wide variety of uses and scales.

A forklift lifts and lowers the fork, which is a loading platform, with a mast, lift bracket, hydraulic device, etc., provided on a transporting vehicle that can freely move by maneuvering, and the entire mast and lift bracket are moved forward and backward to carry and load the cargo. The mainstream is operated by the passenger. In recent years, the scale of the economy and industrial structure has expanded and the distribution of goods has increased in volume as it has become globalized, and the handling of warehouse operations has become smaller and more rods, and there has been a need for complicated first-in first-out. Girls' employment is getting harsh.
As the social population is aging and the birthrate is declining, there is a concern that the labor force ratio will decline with respect to the total population, and companies are making efforts to increase management efficiency and expand overseas for cost reduction. For this reason, the work area of the elderly is narrowed, and provision of a simple and easy-to-handle device is required for elderly and female workers even in warehouse management. Under such circumstances, many disadvantages and disadvantages have appeared in the forklift as a warehouse transfer / transfer device.
(1) Forklifts always require one driver per vehicle. It is difficult to operate and control because it runs in a narrow passage and stacks on the floor board with poor visibility, and in many cases it is also combined with load management such as the name, rod, quantity, loading place etc. of the handled luggage Therefore, both physical strength and brain are hard labor.
(2) In bulk transportation, etc., they are often temporarily stacked and then sorted and unloaded, and unnecessary travel is performed and cannot be ignored for energy saving.
(3) It is easy to collapse because it is stowed and stowed, and it is particularly dangerous for earthquake disasters.
(4) The sum of the minimum turning radius (r) 44 of the forklift itself and the turning radius (R) 45 to the tip of the loaded pallet load etc. 23 (r + R) in order to go straight through the passage and change to the loading place at a right angle Since the right-angle stacking passage width is 46, a passage that is considerably wider than the vehicle width is required, and there is a waste of real warehouse space.
(5) Since the packaged form loaded on the pallet is often uneven and the number of stacks is not constant, it is difficult to directly manage the load using the electronic information processing device.

  In stacker cranes, entry / exit is automated by electronic information processing equipment, and inventory management is also electronic information processing. However, there is a disadvantage that the equipment cost for the load capacity is large and it is not suitable for small warehouses. In a conventional three-dimensional rack building, the storage shelves are almost all of the two-dimensional three-dimensional shelves arranged side by side and up and down. Attempts have been made to transfer using a conveyor, or a dolly running into a three-dimensional shelf, but there is no accurate and low-cost transfer method.

  Japanese Patent No. 3096509   Japanese Patent No. 3356418   Japanese Patent Laid-Open No. 06-156994   Japanese Patent No. 3523715   Japanese Patent No. 3729316   Japanese Patent No. 3757460

  With the declining birthrate and aging of the population, the scale of the economy has expanded, the industrial structure has become global, and there has been a strict need to improve the management efficiency of corporations. Middle-aged and senior citizens are narrowed. The social burden rate of social security increases year by year, and it is inevitable to raise the age of pensioners. In order to improve the employment rate of elderly people, the emergence of devices that can be easily handled by elderly people and girls is awaited. In a declining birthrate and an aging society, in order to maintain a vibrant economy and maintain a welfare standard, the labor force efficiency in all fields and progress in process innovation-type technological innovation will compensate for the decline in the labor force participation rate in the total population. Therefore, there is a need for simple and reliable equipment and facilities that utilize electronic information processing equipment even for equipment and equipment that handles warehouse cargo. The population tends to concentrate in the city, and the distribution of goods tends to gather in the city. With the lack of housing and infrastructure, it is necessary to further improve the building capacity capacity in warehouses and storage areas, and earthquake disasters. In Japan, which cannot be avoided, prevention of collapse of goods is important for disaster prevention and preservation of distribution assets. There is a need for a device and management method that can save energy in waste for temporary storage, unloading, and organization in a forklift cargo handling, due to a large amount of transported cargo, and load it at a predetermined location in one stroke. ing.

As already mentioned, forklifts and stacker cranes, which are currently mainstream equipment for loading and unloading and transporting goods in warehouses and storage locations, have many disadvantages and shortcomings that do not adapt to economic and social changes and needs. It is supposed to be. These points to be improved will be specifically described below.

It is possible to run, stop, position and load / unload a load or to load / unload a load, or to provide equipment and devices that can be equipped with an electronic information processing controller to achieve unattended and automated operations.
(2) A full-time pilot engaged in a forklift eliminates unnecessary unloading and sorting to eliminate the time lag of loading and unloading, completes loading and unloading with only one stroke, and saves energy. By comparing and searching the luggage storage rack and the luggage information symbol, it is possible to smoothly enter and exit.
(3) Instead of direct stacking on the floor using a forklift, the pallet load etc. 23 is stored and stored as one package in a storage shelf in a three-dimensional three-dimensional storage shelf, and the four laps are restrained by mutual loading, or by struts and beams. To prevent collapse due to collapse of cargo and earthquake.
(4) The transport vehicle carrier is horizontally rotated in three directions, 90 ° to the left and 90 ° to the right, and transferred to the three-dimensional three-dimensional storage shelves provided on the left and right sides of the transport vehicle exit / retreat direction. To reduce the waste of the right-angle stacking passage width and improve the load capacity per warehouse volume.
(5) One capsule in a three-dimensional three-dimensional storage shelf is used as one storage base for storing one pallet load, etc., and each is assigned a unique address. Pallet No. In addition, it is possible to attach package information and make them correspond to each other, so that it is possible to carry out storage / shipment management, inventory management, customer management, etc. with an electronic information processor simultaneously with the handling operation.
(6) In stacker cranes, the left and right and top and bottom two-dimensional storage shelves of the stacker crane that occupies most of the stacker cranes are made into three-dimensional storage shelves up to several rows deeper, and can be transferred to it. , To reduce the cost of transport equipment.
(7) Even in a small warehouse / storage location, it is possible to automate the handling of luggage at low cost, and have a floorboard on each floor that is already in operation. To provide a transfer and transfer device that can be refurbished and handled with simple operations or can be automated.

The operation process of the warehouse and the storage place includes receipt of goods, sorting, recording, on-site transportation, warehousing, storage, delivery, transportation, record verification, shipping, etc., and is performed in this order.

  The dolly and the three-dimensional three-dimensional storage rack provided with the minute lifting and lowering loading platform of the present invention are the front rooms of the storage storage rooms on each floor in the whole process of receiving, storing, storing, and shipping the goods at the warehouse and storage place. It is in charge of only the warehousing process, the storage process, and the unloading process to carry it out of the room again. The operation of each device and device during this period will be described in the following three steps.

(1) Warehousing process The pallet load, etc., that has arrived at the terminal roller conveyor 65 of the automatic premises transfer device, is moved to a predetermined position on the unloading station frame 40 by rotating the roller at the ascending position 42 of the unloading station elevating roller conveyor. The lifting roller conveyor is stopped and lowered to the lower position 43 to be placed on the pallet load placing table 38 of the loading station frame base. A dolly loading transport vehicle 49 in which the empty dolly 3 is placed on the storage platform dolly rail 52 stops in front of the loading station frame base, and the dolly mounting transport is operated by an operator on the dolly loading transport vehicle. The vehicle storage platform is raised and stopped in accordance with the height of the delivery station frame base 40, the storage platform dolly rail 52 is rotated by 90 ° from the front, and is connected to the delivery station dolly rail 37 so as to mount the pallet load or the like. This dolly runs directly below the pallet load, etc., placed on 38, with its fine lifting platform at the down position 68. When the pallet load is stopped at a predetermined position just below the pallet load and the minute lifting / lowering platform is set to the ascending position 67, the pallet load is lifted and placed on the pallet load / mounting portion 24. A dolly 3 having a minute lifting platform with a gap A, 31 formed between the bottom surface of the pallet or the like and the top surface of the pallet load or the like can freely run. At this time, the dolly loading transport vehicle receives the pallet No. from the command receiving / transmitting device 41 provided in the loading station frame base. Then, data such as a storage shelf address is read, or is read from a magnetic card, an IC chip, or the like attached at a predetermined position such as a pallet load, and is stored in an electronic information processor provided in the dolly loading transport vehicle. In addition, it is displayed on the monitor so that the boarding operator can read it, crosses the dolly rail to which the main dolly loaded with pallet load etc. is connected, and reaches the predetermined position of the storage platform dolly rail, so that this dolly keeps the function of preventing load collapse during driving The micro elevating loading table is fixed by the dolly fixing device provided on the dolly storage table in the ascending position. The storage platform dolly rail rotates 90 ° and faces in the same direction as the dolly loading transport vehicle.
The dolly loading transport vehicle 49 starts, passes through the warehouse open / close door, travels on the grooved dolly loading transport rail 58 into the warehouse, and is accurately positioned in front of the shelf at the designated address. Stop. The storage platform of the dolly loading transport vehicle moves up and down to the height of the predetermined shelf and rotates 90 ° in the direction of the predetermined storage shelf, so that the storage platform dolly rail 52 is connected to the dolly rail 2 in the rack of the three-dimensional three-dimensional storage shelf. . The operator makes fine adjustments to ensure connection. Here, since the height of the storage shelf is determined for the adjustment in the height direction, it is recommended that the elevator stop position of the storage table be adjusted and fixed in advance. The dolly 3 having the minute lifting and lowering loading table on the storage table is released from the dolly fixing device, enters the main rack while the pallet load or the like is loaded, and reaches the shelf at the designated address and stops. It is easy to detect the position of this dolly while traveling, display it on the monitor, and perform braking / stopping by the operator by detecting the number of rotations of the drive pinion, the sprocket, the number of passing teeth, and the like.
After the dolly provided with the micro lifting platform is stopped at the designated address, the micro lifting platform is lowered to the descending position 68. The gaps A and 31 between the bottom bottom surface of the pallet and the like and the top surface of the storage base 1 such as the pallet load disappear, and the pallet load and the like are placed on the storage base. Furthermore, the loading platform is lowered until a certain gap B, 32 is formed between the lower surface of the pallet and the upper surface of the small lifting platform. Returned. The dolly storage base is rotated 90 °, the dolly 3 is directed in the same direction as the dolly mounting transport vehicle, and is fixed by the dolly fixing device. The dolly mounting transport vehicle lowers the storage table to a predetermined height and moves outside the warehouse. Run to.

(2) Unloading process A dolly equipped with a small lifting platform is empty-loaded, placed on a dolly loading transport vehicle, stopped in front of the unloading station, and a command receiving / transmitting device 41 provided in the unloading station To a storage shelf address such as a pallet load to be delivered to the data reader of the dolly loading transport vehicle, pallet NO. The electronic information processing controller provided in the transport vehicle can also be used to operate a dolly equipped with a transport platform and a small lifting platform even when the passengers read instruction data such as Also, when the operation is made into a control sequence and the unloading operation is performed automatically, this is the reverse process of the above (1) warehousing process, and the description is omitted because it is the same action in the forward and reverse directions.

(3) First-in first-out process When the process including the on-site automatic transfer device becomes complicated and inefficient, it is possible to carry out the loading and unloading station separately in parallel, In this case, the first-in first-out process and the unloading process can also be effectively used. Separately, a first-in first-out tow shelves 72 are made and usually kept at the rightmost end of the rack (the deepest part of the warehouse). Then, a pallet load or the like is temporarily placed on the shelf of the traction shelves.

Since the present invention is configured as described above, the following effects can be obtained.
(1) Since this dolly operates a micro lifting platform with a hydraulic piston and a linear cam, the platform lifting mechanism is simple and low cost. It is structured to load the load by ascending the lifting platform, and to carry it when loading, to unload it by descending the lifting platform, and to run when it is empty. The loading and unloading of luggage is stable and the lifting power is not wasted.
(2) The in-rack dolly rail 2 and the pallet load storage base 1 on the traveling path of the conveying dolly are integrally formed in two stages, and the drive wheel pinion, sprocket and four solid rubber wheels for load support are provided separately. As a result, the distance between the dolly travel rail and the pallet load storage base can be reduced, the warehouse volume loading efficiency can be improved, and the transport dolly travel stability is increased, resulting in more accurate operation.
(3) Since the storage base such as a pallet load is configured by providing a trapezoidal notch, the overall weight of the storage rack can be reduced.
(4) A dolly provided with a small lifting platform is attached to the dolly loading transport vehicle 49, and the accommodation platform dolly rail 52 is rotated by 90 ° to connect the dolly rail in the rack for the dolly travel and the accommodation platform dolly rail. Because of the structure that moves on it, the forklift does not require a right-angled turning radius, and the width of the passage can be narrowed, greatly improving the warehouse area loading efficiency.
(5) The rack storage shelves can be made into a three-dimensional structure, the volumetric load efficiency is good, and the operation control of various equipment becomes easy by the reliable addressing corresponding to the X, Y, and Z axes, and the load management in the warehouse can be performed. It is convenient to file with electronic information processor.
(6) At the time of palletizing by the central conductor, the entry / exit shelf address and pallet No. are entered in the command receiving / sending device of the delivery station provided in front of each floor storage room at the same time as filling in the receipt file, inventory file, etc. Sending the instruction data such as, the dolly loading transport vehicle delivers the cargo and reads them at the same time, and instructs the monitor to display the operation and loading location of the dolly equipped with the dolly mounting transport vehicle and the minute lifting platform, or Because of the sequence configuration, the boarding operator can operate with much simpler operation than forklift maneuvering. There is no trouble with the load already stored and there is no steering operation. Middle-aged and girls can be engaged in a declining birthrate and aging society, and it can contribute to securing occupational areas and supplying labor to companies.
(7) Luggage is not floor stacked, but each pallet load, etc. is stored in a single capsule-like storage shelf, ensuring safe operation without the risk of collapsing or falling. Sometimes no cargo collapse occurs, and the effect on disaster prevention and maintenance of distribution assets is great.
(8) Since the packages are put into and out of the predetermined storage racks in one process based on the command issued by the central conductor, wasteful loading and unloading are not performed, and the traveling of the transport vehicle can be saved.

  An embodiment of the present invention will be described with reference to FIGS.

  In order to provide transportation and transfer equipment suitable for a society with a declining birthrate and an aging society, as well as three-dimensional storage shelves for operating it, the deficiencies in transport of warehouses and storage locations, forklifts as transfer equipment, and stacker cranes are revised. In FIG. 1, reference numeral 1 denotes a pallet load storage base, 2 denotes a dolly rail for traveling of the dolly 3 having a minute lifting and lowering base, and the upper upper surface and the lower upper surface of the cross-sectionally U-shaped long member, respectively. It has been applied. Since this is assembled with the support columns 14 and the beams 15 to form a three-dimensional storage shelf, a three-dimensional shelf and a dolly rail can be obtained simply. A storage base such as a pallet load is provided with a trapezoidal cutout 36 to reduce the weight of the entire facility. The dolly rail in the rack is provided with a meshing pinion rack 17 of the dolly driving pinion 16 provided with a micro elevating loading table so as to be located further inside than the inner end of the pallet load storage table, and is limited to the vehicle diameter of the driving pinion. There was no such thing. The lower upper surface of the U-shaped member of the cross-sectional shape is a running rail of the load supporting wheel 20 of the dolly having a minute lifting platform, the driving wheel and the load supporting wheel are divided to reduce the vehicle diameter, and the U-shaped cross-sectional shape The space between the upper and lower parts of the member is reduced to improve the volumetric load ratio of the three-dimensional shelf.

Reference numeral 3 denotes a dolly having a minute lifting / lowering platform, and the minute lifting / lowering platform 7 includes a mounting portion 24 such as a pallet load and a backrest frame 25 standing at right angles thereto. The backrest frame is pivotally supported by a dolly machine part upper fixed bracket 26 provided on the upper part of the dolly machine part vehicle body 6, and the pivotal part serves as a fulcrum for a minute lifting operation and backrest function of the loading platform.
The micro lifting platform 7 is moved up and down by the action of a linear cam 8 that slides back and forth horizontally by the action of a hydraulic piston via a spring cushioning roller 28 attached to the lower back side thereof. As a method for sliding the linear cam, a female screw 10 is provided in the linear cam 8 of the micro-elevating device, and a male screw screw rod 11 that rotates by fitting with the female screw 10 is operated by a driving body to move the linear cam forward and backward. There is something. In this case, it is not necessary to provide the hydraulic pump device in a dolly equipped with a micro elevating loading platform, and the structure is greatly simplified, and there is an advantage that the overall weight is reduced.

  Reference numeral 5 denotes a loading unit vehicle body of the dolly 3 having a minute lifting loading table, and 6 denotes a mechanical unit vehicle body thereof. In this way, the Dolly vehicle body with a small lifting platform is divided into two functionally and structurally, so that only the devices and axles necessary for the operation of the loading platform are provided on the vehicle body of the dolly loading machine. In any case where the dolly equipped with the micro elevating and loading platform of the present invention and the three-dimensional storage rack are operated, the front of the load is always in the airspace 30 and does not interfere with the vehicle body. Since the vehicle length can be secured sufficiently, it is possible to provide a large number of devices such as drive devices, hydraulic devices, control devices, etc., and the pallet load storage table 1 and the dolly rail 2 in the rack without impairing the lifting / lowering function of the minute lifting platform It is possible to reduce the vertical distance between the racks and increase the volume capacity of the entire rack.

31 indicates a gap A between the lower surface of the pallet load and the like and the storage base 1 of the pallet load, 32 indicates a gap B between the lower surface of the pallet load and the like and the surface of the minute lifting and lowering loading surface. The pallet load or the like can run without contacting the storage table, and the empty loading dolly can be driven without contacting the lower surface of the pallet load or the like by creating a gap 32 when the loading table is slightly lowered.
The small lifting platform of this dolly has the function of preventing the baggage from toppling by the action of the fulcrum 27 and the linear cam 8 so that the loading platform tilts backward. The forklift mast inclination angle is specified to be 10 to 12 degrees backward. However, since this dolly always runs on a flat and well-finished rail, it is sufficient to tilt 8 to 10 degrees. In terms of angle, the lifting / lowering stroke of the small lifting platform of this dolly is the smallest at the end of the loading platform and is approximately 10 to 12 mm. This means that the lifting and lowering operation is stable, but the installation dolly rail 2 in the rack 2, the pallet load storage table 1, the loading station dolly rail 37, the pallet load storage table 38, the storage table dolly rail 52, etc. It shows that sufficient consideration is required for stability against weighted rigidity. In particular, the connecting portion of the in-rack dolly rail 2, the receiving table dolly rail 52, and the delivery station dolly rail 37 must be rigid and fine. It is essential that the pallet to be used has a good bottom finish and that no deflection occurs.

  In order to make the lifting / lowering stage of the minute lifting / lowering platform have a sufficient margin, the upper part of the backrest frame is mounted on the pallet load or the like without being fixed to the bracket 26 fixed to the upper part of the machine body 6 of the dolly. A cylinder with a slightly longer stroke at the front part of the mounting part 24 for the pallet load etc. and a cylinder shorter than that at the rear part of the pallet load or the like. It is recommended to use a dolly that erects a hydraulic cylinder 12 and supports the tip of the cylinder's piston on the back of the mounting part, such as a pallet load, to raise and lower the minute lifting platform 7 and tilt backward. It is done. This is the best mode for carrying out the present invention corresponding to all situations such as the actual state of luggage, installation of storage shelves, the structure of the dolly rail, the structure of the dolly mounting conveyance vehicle, and the state of the rail.
