is suspended, and a stopper plate 71 is attached to the pivot shaft 9.
are stretched in the radial direction.

A part of the stopper plate 71 has a through hole 75 in which a stopper rod 73 installed on the rotating chief fluro 5 engages.
The stopper rod 73 is configured to be moved up and down by a stopper handle 77 via a spring 73a.

Next, as shown in FIGS. 3 and 8, the support link mechanism 13 includes two curved links 13a and 13b of different lengths (four in total).

The base ends of 13c and 13d are rotatably supported by brackets 793 to 79d installed at the four corners of the turning table 65, and two links 13a, 13b and 1
3c and 13d are combined and connected to form a V-shape.

The tips of the two short links 13a and 13b are connected to the long two links.
The links 13c and 13d of the book are rotatably connected to the tips of the links 13c and 13d via bolts 81.

It is in contact with 3.

The weight detection device 67 consists of a second air bag 85 that is provided on the lower surface of the rotating table 65 and to which constant air pressure is always supplied, and the detection rod 83 that is provided at the upper end of the second air bag 85. The second air bag 85 is placed on a support frame 65a suspended from the lower surface of the rotating table 65.

As mentioned above, a constant amount of pressurized air (for example, pressurized air corresponding to the strength of the racks in warehouse A) is always introduced into the second air bag 85 from a pressurized air supply source (not shown).
Due to the pressure of the pressurized air introduced into the second air bag 85, the links 13c, 1
The tip of 3d is always supported with a predetermined pressure.

A limit switch 87 is provided on the rotating table 65 to detect the lower limit position of the upper frame 15, and this limit switch 87 detects the position when the upper frame 15 has descended below a certain level. It sends a signal to an overload indicator and an overload buzzer (not shown).

In other words, the limit switch 87 detects when a load (heavy object 59) that exceeds the set load is applied to the upper frame 15, and prevents such a load (heavy object 59) from being stored in the multi-story warehouse A. In other words, it serves as a safety device to prevent damage to the racks in warehouse A.

Next, a stopper mechanism 89 is provided on one side of the bogie frame 7 to stop the intermediary device 1 at a predetermined position on the traveling rail 3. A stopper bolt 93 is provided on the flange 91 so as to be movable up and down toward the upper surface of the running rail 3.

When the intermediary device 1 is to be stopped at a predetermined position on the traveling rail 3, the stopper bolt 93 is lowered and brought into contact with the upper surface of the traveling rail 3, and when the intermediary device 1 is to be moved, the stopper bolt 93 is lowered and brought into contact with the upper surface of the traveling rail 3. 93 is pulled up along the flange 91, and the stopper bolt 93 is fixed at that position.

In FIG. 2, reference numeral 95 denotes a phototube for positioning the intermediary device 1 at a predetermined position relative to the forklift crane B, and by aligning it with a light receiver (not shown) provided on the forklift crane B, it is possible to transport the heavy object 59. This is to make the work smoother.

Further, reference numeral 97 indicates a first air bag 43 interposed between the upper and lower lifter frames 21a and 21b, and a weight detection device 67.
99 is an air supply/exhaust operation panel, and 101 is an intermediary device 1.
This is an electric operation panel that operates electrically.

Next, the pallet 55 on which the heavy object 59 is placed is, as shown in FIGS. 9, 10, and 11, made of a channel made of light metal (aluminum alloy, etc.) and configured in a rectangular shape.
An upper lifter frame 2 is mounted on the upper surface of the pallet 55.
Elongated holes 57 through which a plurality of guide rollers 25 erected via the support frame 23 are inserted are provided in parallel on 1a.

Next, the functions of the present invention having the above-mentioned configuration are as follows: separating the heavy object 59 and the pallet 55, and detecting the weight of the heavy object 59 placed on the rotating upper frame 15. I will explain them separately.

(a) Effect of separating heavy objects 59 and pallets 55 In FIG.
The heavy objects 59 (molds, etc.) placed through the warehouse A are taken out of the warehouse A by a forklift crane B that runs sideways along the running rail D laid within the warehouse thickness A.
Transfer onto the intermediary device 1.

The intermediary device 1 is moved in advance to a position corresponding to the forklift crane B, that is, to a position where the phototube 95 provided on the lower rotating pedestal 11 of the intermediary device 1 and the light receiver (not shown) provided on the forklift crane B coincide. I'll keep it.

When a heavy object 59 is placed on the casing 17 of the intermediary device 1 via the pallet 55 in such a state, the limit switch 63 provided on the casing 17 causes the pallet 55 and the heavy object 59 to be placed on the casing 17. It detects that the pallet is placed at a predetermined position, and sends the signal to a pallet placement display device (not shown).

From this state, the work of separating the heavy object 59 and the pallet 55 is started.

The guide roller 25 erected on the upper lifter frame 21a is lowered from the upper surface of the casing 17, that is, the first air bag 43 is contracted, and the link mechanism 1
9 is folded and the upper lifter frame 21 is in its lowest position, pressurized air is supplied from an air supply source (not shown) into the first air bag 43 through the air supply/discharge pipe 45.

When pressurized air is introduced into the first air bag 43, as the first air bag 43 expands, the upper lifter frame 21a and the guide roller 25 rise toward the top of the casing 17 via the link mechanism 19. .

This operation will be explained in further detail based on FIGS. 5 to 7.

That is, when the first air bag 43 starts to inflate, the upper lifter frame 21a is pushed up by the upper surface of the first air bag 43, and at the same time, the upper and lower lifter frames 21a are pushed up.
Links 35a to 35d pivotally connected to opposing frames 33a to 33d of 1a and 21b stand up from the lower lifter frame 21b.

That is, one end of the links 35a to 35d is rotatably supported on the wall surface of the lower lifter frame 21b via a pin, and the other end is supported along the frames 33a to 33d of the upper lifter frame 21b via running rollers 39a to 39d. Since it is configured to slide, when the upper lifter frame 21a rises as described above, the links 35a to 3
As the running rollers 39a to 39d provided at the other end of the link 5d approach each other, the entire links 35a to 35d start to rise.

Next, as the upper lifter frame 21a rises,
A plurality of guide rollers 25 erected on the upper surface of the pallet 55 via a support frame 23 are inserted into a plurality of elongated holes 57 provided in the pallet 55, and when the upper lifter frame 21a rises, the guide rollers 25 are A heavy object 59 is levitated from the upper surface of a pallet 55.

Note that the position of the nut 53 of the stopper bolt 47 that regulates the upper limit position of the upper lifter frame 21a is set in advance so that the heavy object 59 can be floated from above the pallet 55 via the guide roller 25. be.

Although not shown, the lower lifter frame 21b includes
A limit switch is provided that detects the lower limit position of the upper lifter frame 21a and transmits a signal for allowing use of the intermediary device 1.

When the operation of floating the heavy object 59 from the upper surface of the pallet 55 via the guide roller 25 as described above, that is, the separation operation, is completed, a worker or the like pushes out the heavy object 59 along the guide roller 25 and moves it to a cart for the next process. Transfer onto C.

Note that if the intermediary device 1 and the cart C for the next step are far apart, the intermediary device 1 is moved along the traveling rail 3 so as to approach the cart C.

In this case, the stopper mechanism 89 provided on the bogie frame 7 is operated as appropriate to stop or move the intermediary device 1 at an appropriate position on the traveling rail 3.

In addition, although the above-mentioned separation operation has been explained only for the separation operation of one heavy object 59, a large number of heavy objects 59 are placed on the casing 17 via pallets 55, and these pallets 55 and heavy objects 59 When the two are separated at the same time, the same operation as above is used.

In addition, in this case, if only one of the many separated heavy objects 59 is to be transferred to the next process C (cart C), the upper and lower rotating The frames 15 and 11 are rotated by a predetermined angle about the pivot shaft 9 of the truck frame 7.

To rotate the upper and lower frames 15 and 11, as shown in FIG. The engaged stopper rod 73 is pulled up against the elastic force of the spring 73a to release the retained state.

As a result, the upper and lower frames 15 and 11 can rotate around the pivot shaft 9 erected on the truck frame 7, and can rotate to a desired position as well as hold a predetermined heavy object 59.
can be transported onto the cart C smoothly and quickly.

In the above embodiment, the first air bag 43, which expands and contracts by introducing pressurized air, is used as a means for raising and lowering the upper lifter frame 21a, but the first air bag 43 is not limited to this. It may be raised or lowered.

(b) Weight detection function of the heavy object 59 This weight detection function of the heavy object 59 does not detect the weight of the heavy object 59 taken out from the multi-storey warehouse A via the pallet 55, but rather detects the weight of the new heavy object 59. Three-dimensional warehouse A
It performs its function when stored in a rack.

That is, the racks in multi-storey warehouse A are designed in advance to be strong enough to support up to a certain weight.

Therefore, the heavy object 59 whose weight exceeds the strength of the rack,
If a large number of items are stored in multi-storey warehouse A, it will be in an extremely dangerous situation.

For this reason, knowing the strength of the racks in the multi-storey warehouse A in advance and not storing items 59 that are heavier than that strength is the most appropriate measure in terms of safety.

Therefore, in this embodiment, the intermediary device 1 is equipped with a function of checking the heavy objects 59 stored in the multi-storey warehouse A by comparing them with the strength of the racks, that is, a weight detection function.

This weight detection function is achieved by, for example, introducing air pressure corresponding to the strength of the rack into the second air bag 85 in advance as described above, and when a weight greater than this air pressure acts, this is detected and shown in the figure. This system sends a signal to the overload indicator and overload indicator buzzer to notify the rack of a dangerous condition.

The operation will be explained in detail below.

For example, when a heavy object 59 that is less than the pressurized air introduced into the second air bag 85 is placed, the weight of the heavy object 59 is supported by the air pressure introduced into the second air bag 85. Therefore, the upper rotating pedestal 15 on which the heavy object 59 is placed does not descend, but maintains that state.

Next, when a heavy object 59 having a weight greater than the air pressure introduced into the second air bag 85 is placed on the casing 17 of the upper swing frame 15, as shown in FIGS. 3 and 8, , brackets on the rotating table 65) 79a to 79d
The links 13a to 13d, which are combined and connected to each other to form a V-shape, are pressed downward by a metering adjustment bolt 29 attached to the bottom support frame 31 of the casing 17.

That is, the links 13a to 13d are mutually V as described above.
Two long links 13 connected to form a letter shape
The tips of c and 13d are in contact with the detection rod 83 of the second air bag 85, so the metering adjustment bolt 2
When the links 13a to 13d are pressed downward via the link 9, the second air bag 85 is compressed and lowered, and at the same time, the casing 17 on which the heavy object 59 is placed also lowers along the upper and lower stopper bolts 27.

When the casing 17 further descends below a certain set level, it comes into contact with a limit switch 87 provided on the revolving table 65.

When the bottom of the casing 17 comes into contact with the limit switch 81, a signal is sent from the limit switch 87 to an overload indicator and an overload buzzer (not shown), and an inappropriate display is displayed for the heavy object 59 to be stored in the warehouse A. It will be done.

The reason why the links 13a to 13d are connected to each other in a V-shape is because the heavy object 5 is
9 is placed on it, it is always lowered while maintaining a horizontal state, and it is also designed to prevent horizontal vibration due to eccentric loads.

That is, even if the load of the heavy object 59 acts on only one link 13a, for example, each link 13a to
13d is connected at its tip by a bolt 81, so that each link 13a to 13d as a whole descends on average.

Note that the weight detection device 67 in the above embodiment detects a heavy object 59 placed on the casing 17 by a second air bag 85 using pressurized air and a limit switch 87.
However, the present invention is not limited to this embodiment; for example, the weight may be detected by a cylinder using hydraulic pressure and a detector that detects the pressure oil supplied to the cylinder. good.

Further, instead of the second air bag 85, a spring having a certain elastic force may be interposed.

As can be understood from the description of the embodiments above, the gist of the present invention is as described in the claims. It is extremely easy to carry out the work, and when transferring pallets or heavy objects to a cart, etc. for the next process, it is easy to align the pallet, etc. with the cart, etc., and problems such as lifting can be avoided. This makes it possible to easily transport pallets and the like without causing problems.

It should be noted that the present invention is not limited to the above-described embodiments, but can be implemented in other embodiments by making appropriate design changes.
