DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention utilizes a shelf truck having a plurality of upper and lower sliding shelves, and loads articles on the shelves onto a transport vehicle for actual transportation. The present invention also relates to a method of transporting goods using a shelf truck in which the goods are loaded into a transport vehicle in an empty state and returned.

Conventional structure and its problems Conventionally, as seen in Utility Model Application No. 74128 of 1982, for example, columns were erected from the four corners of a horizontal beam with casters at the bottom, and vertical beams were assembled between the columns. A pallet with drawers in which a plurality of upper and lower guide rails are attached to the opposing inner surfaces of the pillars and vertical bars, and drawer bodies (sliding shelves) are arranged between the opposing guide rails via sub-rails. (shelf trolley) is provided. When transporting by a transport vehicle using such a shelf truck,
Since the assembled shelf cart is in a rigid state, the volume (occupied space) when transported empty (when returned) is the same as when the actual transport is carried out, and therefore the volume (occupied space) is the same as when transported in a single transport. Both amounts are the same.

OBJECT OF THE INVENTION The object of the present invention is to provide a method for transporting goods by using shelf carts that can be made compact as a whole during empty transportation (reverse transportation). It is in.

Structure of the Invention In order to achieve the above-mentioned object, the present invention provides a method for transporting goods using a shelf truck, in which the shelf truck is provided with a base having wheels, and a pair of side frames attached to both sides of the base so as to be able to rise and fall freely. , shelf support rails installed in multiple stages above and below on opposing surfaces of these side frames, a removable ceiling frame between the upper parts of both side frames that are fixed upright, and a shelf support rail that extends in the front-rear direction between the opposing shelf support rails. At the first location, shelves are inserted every few vertically in the vertical direction with respect to the shelf support rail, and with articles placed on these shelves, the shelf cart is The goods are loaded onto a transport vehicle and transported from the first location to the second location. At the second location, the goods are first unloaded, and then one of the empty shelf trolleys is loaded onto a specific shelf trolley. Relocate the shelves of other shelf carts to the unused shelf support rails, then remove the top frame of the other shelf cart, fold both side frames onto the base, and then stack the top frame on top of it. Thereafter, the specific shelf cart and other folding shelf carts are loaded onto a transport vehicle either separately or all together, and are returned from the second location to the first location.

Embodiment and operation An embodiment of the present invention will be described below based on the drawings. In FIGS. 1 to 7, reference numeral 1 denotes a rectangular plate-shaped and frame-like base, on which a pair of front and rear free wheels 2 are attached to the lower part of one side, and a pair of front and rear fixed wheels 3 to the lower part of the other side. is installed. At the four corners of the base 1, support legs 4 which are open to the inside and are L-shaped in plan view are erected and fixed, and at the lower ends of these support legs 4, a receiving tray 5 having a downward receiving surface is attached. Side frames 6 are attached to both sides of the base 1 so as to be able to stand up or fall down. That is, the both side frames 6 are composed of a pair of front and rear vertical members 7, a plurality of upper and lower horizontal members 8 that connect the vertical members 7 facing each other at the front and rear, and damp plates 9 attached to the outer surfaces of these horizontal members 8. A swing pin 10 is provided protruding from the lower ends of the front and rear surfaces of both vertical members 7, and a locking pin 11 is provided at a position slightly above this.

A vertical guide groove 12 is formed in the front plate or the rear plate of the support leg 4 from the middle part to the lower part to allow the swing pin 10 to rotate and slide. A positioning recess 13 in which the locking pin 11 can be freely engaged and detached from above.
is formed. A plurality of upper and lower shelf support rails 14 in the front and back direction are installed at predetermined intervals on opposing surfaces of the both side frames 6, and the shelf support rails 14
A shelf support auxiliary rail 15 is installed between the two. The shelf support rail 14 basically has a C-shaped cross section, and has cutout portions 16 formed in the upper flanges at the front and rear ends, and stop portions 16 formed in the lower flanges at the front and rear ends. Convex portion 17
are integrally formed. Furthermore, a stopper piece 18 that projects inward is integrally formed at the location of the convex portion 17. The shelf support auxiliary rail 15 also has a cross section C.
Although it is shaped like a square, there is no cutout, and a convex portion 19 for a stop is integrally formed on the lower flange at the front and rear ends. Reference numeral 20 denotes a top frame which can be attached and detached between the upper parts of both side frames 6 fixed upright, and has hooks 21 at both ends thereof which can be attached and detached from above to the horizontal member 8. A rod-shaped stopper member 22 is attached to the front and rear surfaces of the top frame 20 so as to be able to move up and down. That is, a pin 23 is provided protruding from the front and rear surfaces at a position closer to one of the sides, and a flange 23 is attached to the base end of the stopper member 22.
4 is formed with a long hole 25 in the length direction, and the pin 23 is fitted into this long hole 25. Further, the free end of the stopper member 22 is formed into a pin portion 26, and a vertical hole 27 is formed in the base 1, into which the pin portion 26 can be inserted and removed from above. Further, a locking tool 28 for holding the upwardly moved stopper member 22 in a horizontal state is attached at a position near the side opposite to the pin 23. A shelf 29 is fitted between the opposing shelf support rails 14 so as to be slidable in the front and rear directions. This shelf 29 has the shape of a rectangular flat plate framework, and bearings (rollers) 30 supported and guided by the shelf support rails 14 are attached to both sides of the shelf 29, and at the bottom of both sides at the center in the front-rear direction,
A stopper piece 3 that can freely come into contact with the stopper piece 18
1 is installed. A middle part of a cover 32 is fixed 33 to the upper surface of the ceiling frame 20, and this cover 32
is long enough to cover both the front and rear surfaces,
Further, both free ends 32A can be fixed to the base 1 with, for example, magic tape. 34 is base 1
35 is a band, and 36 is an article.

Next, the operation of the above embodiment will be explained. 1 to 3 show a state in which articles 36 are stored and can be traveled and transported. In other words, both side frames 6
is erected and swung around the oscillating pin 10, and the locking pin 11 is engaged with the positioning recess 13 to fix the side frame 6 upright on the base 1 side. Further, a top frame 20 is attached between the horizontal members 8 via hooks 21. Furthermore, each shelf support rail 1
Shelves 29 are fitted between the four, and articles 36 are placed on these shelves 29. Then, the stopper member 22 is moved downward, and at that time, the long hole 25 is used to make the pin part 2
6 is lowered linearly and engaged with the vertical hole 27. Further, the front and rear surfaces are covered with a cover 32. In this state, it can run freely on the floor, and as shown in FIG. 9, it can be actually transported to the second location by loading it onto a truck 37, which is an example of a transport vehicle, at the first location. This stacking is carried out stably by fitting the upper tray 5 onto the upper end of the lower vertical member 7 from above. The stopper members 22 face the front and rear surfaces of the shelf 29, so that the shelf 29 can withstand vibrations during traveling and transportation.
can be prevented from being withdrawn unexpectedly. Article 36
When taking out the cover 32, first, the cover 32 is raised and folded onto the top frame 20, and the stopper member 22 is moved upward to be horizontally locked to the locking tool 28 as shown by the imaginary line in FIG. Next, the shelf 29 is pulled out as shown by solid lines or imaginary lines at the bottom of FIG. 5, and the article 36 is taken out.
This drawer has a stopper piece 18 and a stopper piece 31.
The bearing 30 is brought into contact with the convex portion 17, thereby avoiding an unexpected situation in which another shelf 29 is pulled out due to vibration during pulling out. Note that the article 36 is loaded in the same manner. After all the articles 36 have been taken out, the empty shelf cart 38 is transported (returned) by the truck 37. To carry out this transportation, the following operations are performed using two shelf carts 38 as one set. That is, all the shelves 29 are pulled out from one shelf carriage 38, and these shelves 29 are replaced by the unused shelf support auxiliary rails 15 of the other (specific) shelf carriage 38, as shown in the phantom line in FIG. inserted in between. And in the other shelf truck 38,
The stopper member 22 is set in the operative position, and the front and rear surfaces are covered by a cover 32. shelf 29
One shelf cart 3 from which was removed (transferred)
8, the top frame 20 is first removed, and then the side frames 6 are turned inward and folded onto the base 1, as shown in FIG. This sideways fall is caused by the side frame 6
and remove the locking pin 1 from the positioning recess 13.

Transportation (return) to the location is as shown in Figure 10.
The loading of the other shelf truck 38 onto the truck 37 is carried out in the same manner as during actual transportation, but since the one folding shelf truck 38A is folded and has a low volume, it is possible to increase the amount of stacking. If the number of actual transports (Fig. 9) and the number of empty transports (Fig. 10) are the same, a loadable space A shown in Fig. 10 is created, and a large number of empty transports can be carried out.

In the above embodiment, the formation ratio of the other shelf truck 38 and the folding shelf truck 38A during reverse transport is 1.
For example, in the case of a system in which shelves 29 are used every two tiers in a real shelf cart 38, it is 1 to 2.
Various combinations are possible. Also the first
Although FIG. 0 shows a system in which the shelf cart 38 and the folding shelf cart 38A are returned at the same time, they may be returned separately.

Effects of the Invention According to the present invention having the above configuration, the following effects can be expected. In other words, after unloading the goods, by transferring the shelves of other shelf carriages to the unused shelf support rails of a certain specific shelf carriage among the plurality of empty shelf carriages, The shelf trolley can be made into a low-volume, compact folding shelf trolley by folding both side frames on the base and placing the top frame on top of it, so the amount of transport per time is smaller than the actual transport. It can be done efficiently by increasing the number of
