Abstract

PROBLEM TO BE SOLVED: To eliminate losses caused by storage space, rigid structures, excessive power facilities and large power expenses in conveying a conventional automobile into and out of a storage compartment or to increase the efficiency of warehouse use by reducing the width of a passage which is greater then the depth of a storage compartment for other article. SOLUTION: The front vertical and horizontal beams of opposite storage structures which are located on one side and of the same compartment scale are formed of C-steel members whose intersecting parts are in communication with each other, with openings of the members pointed outwards. Protrusions at each end of a table having a moving device for causing an article storage truck for each compartment to reciprocate are always kept in the openings, and the table is raised and lowered for movement either by raising and lowering hydraulic equipment supporting the center of the table or by an electric trolley hoist running on an I-shaped rail stretched between the top protruding parts of the front vertical beams of the structures. Alternatively, both devices are used in conjunction to move or raise or lower the table to the designated compartment and cause reciprocation of an article carrying truck.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for loading and unloading articles into a storage box on one side or opposite sides.

[0002]

2. Description of the Related Art Conventionally, in order to carry an article in and out of a storage box, in a small or medium-sized warehouse, the article was taken in and out of a storage shelf together with a pallet by a forklift truck.
Since the forklift truck faces the shelves, its aisle width is about twice the depth of the shelves, and the utilization rate of the warehouse space was very poor. Also, in a large automated warehouse, the mechanism is complicated and relatively high cost is required. In car parking lots, not only driving parking lots but also multi-level parking lots always had wasted space in the building. In addition, there are many types of parking lots that move together with vehicles other than those for the purpose of moving, so that even equipment for loading and unloading buildings and vehicles requires equipment with robustness and high power more than necessary. The power cost was also higher than necessary.

[0003]

When loading and unloading conventional automobiles and other articles into and from the storage, there is a waste of space, a robust structure and excessive power equipment are required, and a large power cost is required. It is to eliminate unnecessary waste, or to narrow a passage width wider than the depth of the storage.

[0004]

One of the features of the present invention is:
Both the vertical and horizontal beams on the front of the building have openings facing the front,
The intersections are in communication with each other both vertically and horizontally.
C-type steel is generally used as the steel material. In the opening, protrusions are constantly inserted at both end portions of the side surface where a table on which a dolly for carrying an article moves to and from a storage is always in contact with a building. Then, the table moves laterally in contact with the building, and when the trolley on it is in the position to move in and out of the building storage, both protrusions are inside the vertical beam so that it can move up and down in the height direction. There is.

Wheels (hereinafter referred to as casters) whose directions change freely are fixedly attached to the tips of the protrusions. Then, the caster hits the inner bottom of the C-shaped steel and smoothly moves the table up and down. By fixing casters on both sides of the protrusion in the lateral direction, it is possible to act as a buffer for lateral movement when the table moves up and down.

Further, even when the upper surface of the table is at the same height as the floor surface of the storage and the projection of the table moves laterally in the groove of the cross beam C-shaped steel on the front surface of the building, the caster at the tip of the projection acts as a buffer. do.

On the table, two rails connected to the inside of the storage cabinet are laid, and a cart on which an article with wheels is placed reciprocates on the rail. As one of the carriage moving devices, a cylinder device along which a rod expands and contracts is installed beside the table, and the rod expands and contracts according to the inflow and outflow of a fluid therein. A small fluid pressure device is attached to the tip of the rod, and the small rod is designed to come in and out of a hole formed beside the tip of the trolley on the storage side. The fluid pressure may be compressed air when the article is lightweight, but hydraulic pressure is generally used. When the truck is put in the storage, the rod of this device is extended with the rod of the small hydraulic equipment attached to the tip of the hydraulic equipment main body in the lateral hole of the truck, and the truck is sent to a predetermined position in the storage. Positioning stoppers for truck wheels are attached to the rails in place.

When the trolley is taken out of the storage on the table, the rod of the hydraulic equipment body is extended, the rod of the small hydraulic equipment at its tip is inserted into the lateral hole of the trolley, and the rod of the body is contracted to place the trolley on the table. Withdraw. The width of the rail and the position of the stopper of the table and the carriage are the same for each storage.

A cylinder height adjusting tool is attached to the tip of the cylinder of the hydraulic equipment main body. When the carriage is pulled out onto the table, the cylinder tip of the hydraulic equipment main body is
It is at the highest position. When the rod of the hydraulic machine body is extended to the predetermined position by the rail stopper in the storage, the tip of the hydraulic machine body is at the lowest height, and the rod of the small hydraulic device is pulled out from the side hole of the cart to remove the hydraulic machine body. The cylinder height adjuster works so that the height of the tip of the hydraulic machine does not change when the rod is returned to the table.

As another method of moving the carriage between the table and the storage, there is the following mechanism. A plate fixed to the side of the two rails installed on the table so that the two chains mounted on each of the two sprockets are interlocked with each other, rotated by the electric motor installed on the table, and passed between the two chains. The suction cup attached to the end of the shaft, which is fixed in parallel with the rail approximately in the center of the, is attracted to the front of the trolley in the storage by the rotation of the chain, and the trolley is pulled back on the table by the reverse rotation of the chain and stored again. Send it to the warehouse.

When the dolly is placed in the storage, an electromagnet function is given to the two stoppers of the trolley rail in the storage,
This is used to stop the wheels of the truck, and the suction cup of the shaft caused by the movement of the chain on the table toward the table is released from the truck. When pulling the dolly onto the table with the shaft sucker, the electromagnet function is canceled.

An elevating device is attached to the lower portion of the table substantially at the center, and the table serves as a mechanism for moving along the building. Lifting devices typically use cylinder hydraulics where a table lifter or rod supports the table. The hoisting device is equipped with a groove parallel to the front of the building so that the lowered table matches the level of the storage on the first floor, so that the traveling vehicle can move along the building. .

The uppermost part of the front beam of the building projects to the front of the building, and a rail made of I-shaped steel or the like is fixed along the structure at the tip of the front beam. Are installed so that they can move along the structure. At the end of the hoist rope or chain,
A portal hanger is attached to its center, and the hanger is fixedly or removably attached to both ends of the table. The table moves up and down and moves laterally by lifting and lowering the hanging device and moving along the building.

Below the both ends of the table on the building side, vertical table horizontal holders for fixing the level of the table are fixedly installed on the building side. One or more castors are attached to the building side. The casters are also in a position to move up and down along the surface of the longitudinal beam when the table moves up and down the building. It should be noted that two horizontal table holders may be attached so that both ends of the table form the grooves of the vertical beam C-shaped steel with their casters hitting both surfaces.

Further, a table horizontal support plate having a vertical width which is sufficient for the casters mounted on the table horizontal holder to run is connected to the front groove forming surface of the cross beam which constitutes the floor of each storage. It is fixed to the thing. If the article placed on the trolley on the table is comparatively light by the table horizontal holder with this caster and the table horizontal support plate under the floor beam of the storage cabinet, the electric traveling trolley hoist installed in the building The table hangers allow you to keep the table horizontal and move up and down along the structure.

Further, by using the table lateral movement lifting device and the lifting device of this electric traveling trolley hoist together, it is possible to move a heavier load between the storage box and the table more than when each device is independently driven and used. You can

Buildings of the same size are installed opposite to each other, and a table elevating device is installed to move between the two ends so that both ends of the building move in the middle. A hydraulic cylinder device for moving the dolly is also installed on the table on the opposite side of the dolly to be put in and out, or a storage device facing a shaft device with a plate sucker fixed to the chain mounted on the sprocket installed on the table rail is opposed. It is possible to share the table traveling up-and-down device for loading and unloading the carts on both sides of the storage by installing the same toward the storage compartment and adding the electromagnet function to the rails inside the storage.

By attaching an electric trolley hoist that automatically travels along a rail installed along the building and a hanging tool attached thereto to both ends on the opposite side of the table, on the extension of the depth beam of the building which is opposed to each other, By simultaneously driving both electric traveling trolley hoists and the lifting device, the table can be laterally moved and moved up and down, and the carts on which the articles are placed can be put in and out of the storage boxes on both sides. In this case, the table horizontal holders fixed to both lower ends of the table, the casters attached to the holders, and the table horizontal support plates fixed to the corresponding structures may be omitted.

By simultaneously using the table lateral movement lifting device, the electric traveling trolley hoist of both structures, and the table suspending device, relatively heavy objects can be carried in and out of the storage of both structures.

[0020]

BEST MODE FOR CARRYING OUT THE INVENTION Specific embodiments will be described below based on Examples.

FIG. 1 is a perspective view showing the structure of each storage on the first floor adjacent to the third floor. Storage building (hereafter building)
The storage cabinets 2 are arranged vertically and horizontally by 1. The size of the building 1 is determined by the size of the storage 2 and the required number.
The height is limited in the case of a lightweight structure, but the table lateral movement lifting device, in many cases the table lifting hydraulic device 1
Determined by 8 abilities. If the weight of a stored item that can be raised and lowered by the electric traveling trolley hoist 24 described later, the height is determined depending on the strength of the building.

At least the front beam of the storage 2 is made of C-shaped steel except for the uppermost cross beam. The front vertical beams 3 and the front horizontal beams 4 are assembled by welding or the like so that the openings are directed to the front and the grooves at the intersections 5 communicate vertically and horizontally. A table 6 on which a dolly 7 on which an article is placed rests on a rail 8 on the table via its wheels, and the side surfaces of the table 6 always move in contact with the front beam of the building, but both ends of the table 6 are always provided with the front beam of the building. There is a table projection 12 which is located in the groove. A projection tip caster 13 is attached to the tip of the projection 12. It acts as a buffer when the table 6 moves laterally along the building 1 and ascends and descends. In addition, the cushioning function can be further enhanced by additionally providing both side projections 14 on both sides of the table projection 12.

The thickness of the table protrusion 12 is made thinner than at least the thickness of the table 6 by an amount corresponding to the width of the upper half side of the groove structure of the building cross beam C type steel. The thickness of the table may be reduced according to the cross section of the table protrusion 12, but C
Outside the shape steel, the thickness may be adjusted according to the vertical width of the cross section.

On the lower surfaces of both ends where the table 6 contacts the building 1, table horizontal holders 15 are fixedly provided under the table. On the side of the building, a horizontal holder caster 16
Is attached so as to go up and down along the vertical beam of the building 1. A plurality of casters 16 is desirable. It is advisable to install two table horizontal holders 15 on one side of the table so as to move up and down along the surfaces on both sides of the groove of the C-shaped steel of the vertical beam. The portion of the table horizontal holder 15 attached to the lower portion of the table is fixed with a width larger than the tip thereof.

At the lower part of the front cross beam of each storage 2 of the building 1, when the table 6 moves laterally along the groove of the cross beam, the table horizontal holding device 15 holds the table horizontal holding at the portion where the casters 16 run. The plate 17 is fixed to the two vertical beams that form the storage together with the horizontal beams. This maintains the horizontality when the table 6 moves laterally.

The table 6 is laterally moved along the table 1 along the building 1 by a table elevating / lowering device attached to the lower center part thereof, and is elevated / lowered so that the table coincides with the floor surface of the storage case 2. The table lifting / lowering moving device may be a table lifter, but in this case, the table lifting / lowering moving hydraulic device 18 is used.

In this machine, the tip rod is attached to the lower part of the table 6 via the flange 19, and the main body cylinder is attached to the lateral movement device 20 so as not to cause a shake in the movement direction. It runs in the lateral groove dug in. A roller 21 is installed on the main body cylinder so as to rotate in contact with the side surface of the groove so that the main body moves smoothly and there is no lateral shake.

At the top of each front beam of the building 1, the front beam projects to the front of the building, and at its tip 22, an I-shaped steel material is fixed as a rail 23 along the building. An electric traveling trolley hoist 24 is attached. From the hoist, a rope or chain 25 is wound up and lowered. A table suspending device 26 is attached to the tip thereof, and the suspending device is fixedly attached to both ends of the table 6 or attached detachably. The table 6 is vertically moved or moved laterally by the electric traveling trolley hoist 24 via the table hanging device 26.

The rails 9 in the storage 2 are arranged at the same intervals as the two rails 8 on the table 6, and are aligned so that the carriage 7 can move between the table and the storage. , There is no hindrance to the mutual movement of the carriage 7. Both rails have stoppers 10 and 11 attached,
The table 6 of the carriage 7 and the storage 2 are stopped at predetermined positions. The top 10 of the table 6 also serves to prevent the dolly from falling.

A fluid pressure device is installed beside the carriage 7 on the table 6, so that the carriage 7 can be moved between the table 6 and the storage case 2. The trolley moving hydraulic equipment 27 is generally used except when the article is light.
A small hydraulic device 28 is attached to the tip of the most advanced rod of the trolley moving hydraulic device 27, and the rod enters a lateral hole formed at the tip of the trolley 7 near the storage case 2 and the trolley is driven by driving the hydraulic device body. 7 moves between the table 6 and the storage 2.

FIG. 2 is a vertical sectional view of the storage case 2 taken along the line AA ′ in FIG. In this case, the thickness of the table 6 is made thick so as not to match the lower end of the table projection 12 in the C-shaped steel and to be the same as the vertical cross-sectional width of the C-shaped steel. If a sheet of fluororesin or polypropylene resin is attached to the surface of the table 6 in contact with the C-shaped steel with adhesive or tacks so that the head does not come out, the table 6 can move the vertical and horizontal beams of the building 1 smoothly. . If the same treatment is applied to the surface of the C-shaped steel table 6 in contact, the effect is further enhanced.

FIGS. 3 to 5 show a method of moving the carriage 7 between the storage 2 and the table 6. Figure 3
Indicates that the carriage 7 is in the storage. The trolley moving hydraulic equipment 27 is installed on the table by a band 29. Since the tip of the trolley moving hydraulic equipment 27 moves up and down, the band 29 is attached to the table 6 and the trolley moving hydraulic equipment 27.
It's fastened to the top of the, but there's plenty of room. Small hydraulic equipment 2 attached to the rod tip in this state
The height of 8 is adjusted by the cylinder height adjuster 30 and the carriage stoppers 10 and 11 of the table and the rails 8 and 9 of the storage so that the center of the height of 8 is at the center of the side hole of the carriage 7 in the storage. It is adjusted.

FIG. 4 shows a state in which the rod of the truck moving hydraulic device 27 of FIG. 3 is extended and the rod of the small hydraulic device 28 is inserted into the lateral hole of the truck 7. The cylinder tip height adjuster 30 of the carriage moving hydraulic device 27 is attached to the tip of the main body relatively. The structure is such that the four sides are frame rails, the adjusting tool rail 31 is fixed along the lateral center of the carriage moving hydraulic device 27, and the adjusting tool 32 is fixed on the table 6 therebelow, and rotates in the center. One of each of the two free-fastening bars is free-moving up and down at the inner end of each adjusting tool near the band 29. The ends of the other bars in the adjusters 31 and 32 are made to move freely within the distal end side of the carriage moving hydraulic device 27 of the adjusters 31 and 32. When the height of the tip of the trolley moving hydraulic equipment 27 of FIG. 3 and FIG. 4 is the lowest, the free ends of movement of the crossed bars are respectively the adjustment tool rails 3.
It is located at the end in the direction of the storage in 1, 32.

FIG. 5 shows a side view of the carriage 7 in which the rod of the carriage moving hydraulic device 27 is pulled into the cylinder and the carriage 7 is pulled out onto the table 6. At this time, the tip of the carriage moving hydraulic device 27 is the highest, and the free ends of the bars of the cylinder tip height adjuster 30 are located in the adjuster rails 31 and 32 near the band 29, respectively.

FIG. 6 is a plan view of the cylinder of the carriage moving hydraulic device 27 when the rod of FIG. 4 is extended most, the rod, the small hydraulic device 28 at the tip thereof, and the rod being extended. In this case, the carriage moving hydraulic device 27 is of a type in which the rod of the main body extends in three stages. The rod may be extended in two steps or four steps.

FIG. 7 is a perspective view of the table 6 and the storage case 2 showing another method of the carriage moving device. Table 6
Sprockets 33 and 34 are attached to both side surfaces of the outer frame of the rail 8 above the rail, and the chain 3 is attached thereto.
5 and 36 are hung. A sucker shaft fixing plate 37 is passed over and attached to the two chains, and a sucker shaft 39 to which a sucker 38 is fixed is fixed at the tip thereof. The sprockets are gears, which are not shown.

The adjacent suction cups 40 and the suction cup shafts 41 fixed to the suction cup shaft fixing plate 37 are used for loading and unloading the trolley 7 into and from the storages of the same size in the opposite building.
Function.

By driving the electric motor 42 installed on the table 6, the sprockets 33 and 34 rotate, and the suction shaft fixing plate 3 fixed to the chains 35 and 36.
7 moves. And the suction cup 38 at the tip of the suction shaft 39
Is applied to the front of the trolley 7 in the storage 2 and the trolley is sucked onto the suction cup. Then, the electric motor is rotated in the reverse direction to pull out the carriage 7 on the table. The rotating shaft 43 is installed so that the rotation of the electric motor is accurately transmitted to the sprocket on the far side.
The rotary shaft support 44 supporting the above is installed on the table 6.

When the carriage 7 on the table 6 is carried into the storage case 2, it is pushed in by the shaft 39 with a suction cup, but when it stops at a predetermined position determined by the rail stopper 11 of the storage case 2, the attached drawing is shown. With no limit switch, the electric motor 42 is stopped. When the sucker shaft 39 is separated from the dolly and returned to the table by the reverse rotation of the electric motor 42, an electromagnet function incorporated into the two rail stoppers 11 of the storage 2 (not shown), which is superior to the sucker force, should be activated. Thus, the suction shaft 39 is separated from the carriage by the reverse rotation of the electric motor, and the carriage 7 is stopped in the storage.

The length of the sucker shaft 39 in FIG. 7 is longer than the depth width of the front beam of the building, and since the trolley is designed to be stored in the storage in the front beam, the trolley stopper of the rail 8 is used. 10 is located near the storage. When the carriage 2 in the storage of the opposing building is put in and out, the sucker shaft 41 and the sucker 40 are made to work and are operated in the same procedure.

This method makes it possible to perform a trolley movement operation without using the trolley movement hydraulic equipment 27 when the articles are carried into and out of the opposed storage building by sharing the table 6.

FIG. 8 shows a method in which buildings of the same structure having the same size and number of storage boxes 2 are arranged in parallel, and articles are carried in and out of the storage boxes of both buildings by the same table 6. . First, the table lifting / lowering moving hydraulic device 18 is shared. FIG. 3 is a vertical cross-sectional view of the building at the same position as in FIG. 2, showing a method of hoisting and hoisting the table using two sets of the electric traveling trolley hoist 24 and the table hoisting device 26. The protrusion of the table moves in the front cross beam and the front vertical beam of the building. Also, the method of keeping the table horizontal is exactly the same. In this case, the mechanism for keeping the table horizontal may be omitted except for the projection structure of the table. However, it is necessary to improve the accuracy so that the projections of the table located in the front beams of both buildings are relatively exactly in the same position.

The trolley moving hydraulic equipment 27 needs to be installed on the opposite side of the table 6 so that the rod works toward the opposite storage, and the rod of the small hydraulic equipment 28 at the tip of the rod moves in and out. It is necessary to open a hole to be formed at the tip of the trolley 7 of each storage box near the storage box.

8 and 9 show the table hanging device 2
6 is a partial view of FIG. The hanging device may be fixed to the table 6.

A procedure for loading and unloading articles into and from the storage box on one side will be described. An operation panel such as an electric switch or a hydraulic control device (not shown) is operated to move each required transportation device to a predetermined location in combination with a limit switch and a relay switch. First, the table 6 is moved to a predetermined storage position and lifted, and the dolly 7 therein is pulled out onto the table by operating the dolly moving hydraulic device 27 on the table. Lower it to the first floor. An article is placed on the dolly 7. In the case of an automobile, a rail corresponding to the tire width that can be relocated may be provided on the dolly. A stopper may be provided on the rail to prevent the automobile from moving. Further, it is advisable to attach an inclined plate for facilitating the movement of the vehicle to the bogie 7 to the table without touching the table hanging device 26. The car may be placed on the dolly in parallel with the building, or may be placed on the dolly toward the storage. The cart 7 on which the article is placed is raised to the storage. The dolly is put into the storage 2 by the dolly moving hydraulic device 27.
When carrying out the stored article, the procedure is the reverse of that when the article is carried in.

The cart 7 on which the article is placed is lifted to the storage. The dolly is put into the storage 2 by the dolly moving hydraulic device 27.
The sprocket and the suction shaft 39 fixed to the suction shaft fixing plate 37 attached to the chain on which the sprocket is mounted
May be stored in the storage 2. The table is moved into the storage case 2 by the table moving hydraulic device 18. When carrying out the stored goods, the procedure is the reverse of the time when the goods were carried in.

For relatively light articles, the electric traveling trolley hoist 24 and the table hanging device 26 are used. For heavy items, the table moving hydraulic device 18 and the electric traveling trolley hoist 24 and the table hanging device 26 are used together. To do.

The procedure is the same when the articles are carried in and out of the opposing storage boxes. However, it is also possible to move the table to the entrance of the building by remote control, place the article on the trolley and store it in a predetermined storage box, or vice versa.

Except when the storage case 2 is in a building, it is necessary to always have a pump for removing rainwater or the like that collects in the groove in which the table lifting hydraulic equipment 18 moves.

In order to prevent danger, it is desirable to carry out and carry out articles by remote control. However, when working under each storage, especially in the case of the storage building 1 on one side, the table is the minimum safety measure. When going out of the building, it is necessary to install an automatic fence to keep people out of the area.

[0051]

The present invention is carried out in the form as described above, and has the following effects.

As a small and medium-sized storage warehouse, since the table and the trolley on it can be made to have almost the same size as the pallet on which the articles are placed, the width between the storages is about one half of the conventional warehouse. Therefore, a large number of storage boxes can be installed in the warehouse, and the storage efficiency is about 1.5 times. Or, if the same number of storages is used, the storage space can be about two thirds.

The small and medium-sized warehouse can be used as an automatic warehouse.

It is possible to make a relatively lightweight steel structure as compared with the conventional automatic warehouse. Also, with a small amount of power, heavy items can be automatically loaded into or unloaded from the storage.

When used as a parking lot for automobiles, it is possible to carry in and carry out automobiles without the need to move the automobiles other than the intended purpose, so that there is no waste of space. In addition, the overall power source equipment can be small, and the running cost of power can be reduced. It should be noted that a structure made of relatively lightweight steel may be used.

In the case of opposing storages, articles can be loaded into and unloaded from the storages on both sides with a single table lifting / lowering device.

In the case of the opposite storages, the electric traveling trolley hoists of both buildings can be used at the same time, so that the table can be moved up and down without moving the table, so that a relatively heavy object can be carried in. You can carry it out.

By using the electric traveling trolley hoist in combination with the table lifting device and the table lifting / lowering device, it is possible to carry in and carry out a considerable amount of heavy objects.
