[Detailed description of the device]

[0001]

INVENTION The present invention relates are those which relate to a preferred rose was transfer device for laborsaving a cargo handling operation of the weight thereof.

[0002]

Cranes are the most well known and widely used equipment for loading and unloading heavy objects. Due to its excellent versatility, cranes are installed at many work sites.For example, in a factory that handles items that are too heavy for people to carry, an overhead crane is almost always installed at the top of the building. Has been.

However, depending on the contents of the cargo handling work and its object, it may be possible to improve the work efficiency or save labor by using a dedicated machine for the cargo handling instead of the crane. As an example, when a certain object is transported by repeating certain simple operations, a dedicated machine can work efficiently with less human labor than a crane, and the equipment cost does not increase due to the simple operation. There are many. In a factory that includes multiple work sites, the working hours of the cranes overlap between each site, and the work is prone to be delayed because other cranes hinder the transportation of objects by one crane, so the dedicated machine is It is also preferable in terms of improving the work efficiency of the entire factory. In addition, if the object of a certain cargo handling is extremely heavier than other cargo handling objects in the same factory, or if special handling is required due to the nature of the cargo, a dedicated machine is better than a crane. Is suitable. Japanese Utility Model Laid-Open No. 59-64214 introduces a kind of special-purpose machine for transporting panel-shaped concrete blocks without using a crane.

On the other hand, in the case of using a container to transport loose objects to another place, the cargo handling work can be saved by the structure of the container. For example, if another hook is required for tilting the container and opening / closing the bottom plate in addition to the hook for hanging the container, the crane requires two sets of hooks, etc. It will be difficult to work, but if the container has a structure that allows the bottom plate to be opened and the contents to be taken out without having to hang it in two places, a simple crane can be used and cargo handling work becomes easy. Actual exploitation 63-11
The cargo handling bucket described in Japanese Patent No. 485 is a container configured with that in mind, and after being suspended and carried to a desired position, the bottom plate is opened by a simple operation, and the loose material inside is put into another container or the like. Can be transshipped.

[0005]

[Problems to be Solved by the Invention] Depending on the conventional cargo handling means including the ones introduced above, the transportation of particularly heavy objects (for example, objects of more than 1 ton) is labor-saving so as to be unmanned. It was impossible to do. The reason is as follows.

(A) Since the crane is configured to have versatility as one purpose, a crane automatically carries out a series of works such as hanging a certain object on a hook, transporting it to a specific place, and hanging it. In the first place, it is unsuitable. In particular, the fact that the hanging rope or the suspended object shakes greatly hinders the automation and labor saving of the cargo handling work.

(B) Unlike the crane, the device described in Japanese Utility Model Laid-Open No. 59-64214 is not expected to be capable of automating the carrying work, but due to its structure, it is not suitable for carrying heavy objects. Not suitable. Since the gate-shaped frame travels while the transported object (concrete block in the publication) is held at the lower end of the screw shaft, the bending force (bending force) is applied to the screw shaft based on acceleration, vibration, shaking, etc. during running. Moment) is generated. If the weight of the object is heavy, the unreasonable force will be applied to the screw shaft, so it can be said that it is not suitable for carrying heavy objects.

C) In the cargo handling bucket of Japanese Utility Model Laid-Open No. 63-11485, the operation of manually releasing the lever of the lock mechanism even if a crane (hook) or the like is not required to open the bottom plate of the lifted bucket. Is necessary,
It cannot be used as it is in order to save labor to the extent that it can be unmanned. In addition, since containers such as cargo handling buckets only have the function of accommodating and discharging loose items, the function of moving the loose items into another container, etc. It is necessary to construct a total device that is combined with other devices having the above.

The object of the present invention is to move a heavy object of more than 1 ton with almost no annoyance to the operator .
In particular, transshipment of bulk items should be done in an unmanned state
Is to provide a transshipment device that can

[0010]

[Means for Solving the Problems] Bulk object transshipment of the present invention
The apparatus is a) a cargo handling cart that includes a frame with traveling wheels and hoists and moves an object. The hanging hook is rotated in the front-back direction of the hook to make the hook almost vertical. Attached to the bottom of the hook block (lump or frame-shaped one) via a switching means that changes the direction between,
A loading platform in which the hook block is connected to the lifting means and a guide frame for lifting the hook block is provided integrally with the frame.
It is equipped with a car and its running track.

This transshipment device is used for the cargo handling cart of the above a).
In addition to the traveling track, b) a hooking member (such as a suspension ring and a rope) for being lifted and a bottom plate that is closed and opened corresponding to the lifting and lowering of the hooking member,
A cargo handling container that accommodates loose items and is hung by the above cargo handling cart to move, and c) to support the cargo handling container at the upper part of the receiving space for bulk items from the cargo handling container so as not to prevent the bottom plate from opening and closing. It is a combination of the container support stand provided.

[0012]

The loading trolley of the bulk material transshipment device of the present invention is for loading and unloading objects to be loaded (objects, that is, the above b).
Lift and move the container as follows. That is, when the object is ready in the given storage space,
The cargo handling truck approaches the object by traveling on the track installed above it. It is good practice to keep the hook block retracted upwards and keep the hooks almost horizontal while traveling.

The loading trolley stops right above the object and hooks on the hooked portion (hanging member referred to in the above b) such as a beam for lifting or a rope / hanging ring).
To this end, the hook block is lowered to just above the hooked portion by the elevating means, the hook is rotated vertically downward by the switching means to put the hook tip into the hooked portion, and the hook block is slightly raised by the elevating means. . The hook rotates in the front-back direction of the hook (that is, in the plane including the center line of the hook), and the guide frame prevents the hook block from swaying, so the hook smoothly enters the hooked part and rises. When you do so, be sure to catch it.

The object is lifted by further raising the hook block by the elevating means, and the dolly moves the object by traveling in that state. During this period, the hook block does not shake due to the action of the guide frame, so that the shaking of the object can be minimized.

When the vehicle reaches a predetermined position, the carriage stops,
Lower the hook block to lower the object to that position. Also during this time, the object hardly sways due to the guide frame, so that the object can be lowered to the predetermined position with considerably high accuracy. When it is not necessary to move the object continuously after the object has been unloaded, the hook is moved substantially horizontally by the switching means to be removed from the hooking member, and the carriage is moved to another position.

As described above, in the cargo handling trolley in the device of the present invention , the hook can be hooked on the object without the operator's hand, and the shaking of the hook and the object can be suppressed. The operation can be performed reliably and smoothly even under the condition that the labor is reduced. And as long as the initial storage space for the target object and the unloading space afterwards are constant, automatic stop at that position is realized with the assistance of switches and sensors, which eliminates the need for workers and observers. Unmanned driving is also possible.

Further, since the guide block prevents the hook block from swaying, no matter what type of lifting means is used, no unreasonable force acts on it. Therefore, even if the object to be handled is a heavy object and the object is stably supported, the object can be stably supported and moved.

The bulk material transshipment device of the present invention is provided at the above-mentioned cargo handling cart (a)) and the above-mentioned cargo handling container b), and at the position for unloading the cargo handling container and receiving the bulk material. Using the container support stand of c), the bulk material in the cargo handling container is transferred to the receiving place (or another container there) as follows.

1) The cargo handling container of b) is used as a cargo handling object, and the cargo handling cart hooks the hook on the hooking member of the cargo handling container in the manner described above. Up to this point, the container has been placed on the ground or on another trolley in contact with a bottom plate or the like, and the loose object is stored in the container, that is, on the bottom plate.

2) According to the above procedure, the cargo handling truck hoists the cargo handling container and moves it on the traveling track to above the container support stand. Since the bottom plate of the container is closed and opened corresponding to the raising and lowering of the hooking member, the bottom plate of the container is in a closed state and is not opened while the hooking member is hooked and lifted.

3) When reaching the receiving place for the bulk material, the cargo truck unloads the cargo container on the container support frame as described above. The container support stand is located at the upper part of the receiving space for loose items, and supports the container so as not to interfere with the opening and closing of the bottom plate, so when the container is placed on the stand and the hook of the dolly is further lowered to lower the hanging member, The bottom plate opens due to the weight of the loose material in the container, and the loose material in the container is discharged to the receiving place.

The lifting and movement of the cargo handling container and the lifting and lowering of the cargo handling container onto the container support cradle can be surely performed by the cargo handling cart as described above , and the cargo handling container is hung and moved by the retaining member, and Since the contents can be dispensed only by being properly placed on the support base, this transshipment device makes it easy to automate the work of moving the loose material in the container to the receiving place.

1 to 3 show an embodiment of the present invention. In this example, scrap (scrap iron), which is a loose piece, is separated from the cargo handling container (scrap box 20) shown in FIG. Regarding the device to transship to. The scrap box 20 is preloaded with a predetermined amount of scrap on the weighing carriage 3 at a position (weighing field) other than that shown in FIG. When you arrive at the position shown in
The weighing trolley 3 and the weighing trolley 3 approach it as shown in the figure, and the scrap contained therein is transferred into the basket 6. In addition, box 20
There are two sets each (and the weighing cart 3) and the basket 6 (and the transport cart 5) as shown in the figure, but each of them accommodates about 40 tons of scrap at one time.

In the present embodiment, as a means for moving the scrap box 20 on each weighing carriage 3 which has come to a predetermined position onto each basket 6, as shown in FIG. Place each basket 6
Support frame 30 for the box 20 above the rest position of the
Is provided. Further, in order to provide a vertical positional relationship between them, the structure 1 is provided in addition to the steel frame structure of the building. Hereinafter, first, the configuration of the cargo handling vehicle 10 will be described.

The cargo truck 10 is constructed as shown in FIGS. 1 (a) to 1 (d), and is arranged on the traveling track 1a laid on the structure 1. First, the main body of the carriage 10 is configured to be self-propelled by providing the four wheels 12 on the frame 11 and mounting the traveling drive means 13. Further, a hoisting drive source 14a including a motor, a speed reducer, a sheave, and the like, and elevating means 14 including a plurality of pulleys 14b and a wire rope 14c are provided, and a hook block 15 is connected to the rope 14c.

The hook block 15 has two hooks 16 attached to its lower portion as shown in FIG. 1 (b). However, the switching means 17 provided in the central portion, that is, the rotation of the electric cylinder 17a as shown in FIG. 1 (d). By the mechanism combined with the arm 17b, these two hooks 16 can be horizontally and simultaneously
It is possible to switch between vertical. Since the switching is performed by rotating the hook 16 in the front-back direction of the hook 16a as shown in the figure, the hook 16a smoothly enters the lower side of the suspension beam 23 of the scrap box 20 by the switching.

A guide frame 18 for the hook block 15 is formed integrally with the frame 11 on the cargo truck 10. As shown in FIGS. 1 (a) to 1 (c), the guide frame 18 is a guide rail-shaped bracket that surrounds the left and right ends of the block 15 from the front and rear and both ends, and is along the ascending / descending path and the entire height of the ascending / descending range. It is provided over. In addition, free rollers 15a are attached to both ends of the block 15 particularly for the purpose of smoothing up and down. The block 15 is in a state in which the roller 15a is always in contact with the guide frame 18, so that the block 15 hardly shakes during the traveling of the carriage 17 or when the carriage 17 is stopped.

Scrap box 20 shown in FIG.
Is a movable and openable bottom plate 22 on the outer plates 21 on the four sides.
And a hanging beam 23 which is a hanging member for lifting, a first bracket 24 integrally connected to the beam 23 and the bottom plate 22 via a rod 22b, and a second bracket 25 fixed on the outer plate 21. are doing. Bottom plate 2
2 can be opened downward with supporting pins 22a near both ends as fulcrums, but as shown in FIG. 2 (b), the box 20 is in contact with the bottom surface (or by using the first bracket 24), the weighing carriage 3, etc. When placed on, it remains closed. In addition, even when it is lifted up by the hanging beam 23 (the hooked portion 23b thereof), the bottom plate 22 is pulled up through the rod 22b and kept closed as in the case of being placed using the first bracket 24. Be done. However, as shown by the phantom line in FIG. 2A, the box 20 is placed so that the second bracket 25 is mounted on the support frame 30,
When the suspension beam 23 is free, the bottom plate 22 opens downward while pulling down the first bracket 24 and the suspension beam 23 due to its own weight and the weight of the scrap inside.

In the apparatus configured as described above, scraps are reloaded from the weighing cart 3 shown in FIG. 3 to the basket 6 on the transport cart 5 as follows. Note that the following operations in this device are all automatically performed except when there is an abnormality, according to a sequence control system that includes a control device (not shown) such as a limit switch.

1) When the weighing trolley 3 carrying the scrap box 20 containing scraps stops at the position shown below the track 1a for the loading trolley 10, the trolley 10 comes right above it and stops. The hook block 15 is lowered to a position directly above the hanging beam 23 of 20 and the switching means 17
The two hooks 16 are hung on the hanging beam 23 using the above.

2) The trolley | bogie 10 lifts the box 20 by raising the block 15 by the raising / lowering means 14,
By traveling in that state, the box 20 is transported to the predetermined position shown in the figure, that is, to the top of the basket 6 below the support frame 30. Since the block 15 does not swing due to the action of the guide frame 18, the swing of the box 20 during this period is extremely small.

3) When the trolley 10 reaches the pedestal 30, the trolley 10 is stopped and the block 15 is lowered to lower the box 20 on the pedestal 30. At this time, since the second bracket 25 of the box 20 is placed on the pedestal 30 as shown in FIG. 2A (phantom line), the bottom plate 22 of the box 20 is opened and the scrap is discharged into the basket 6.

4) After the whole amount of scrap has been transferred to the basket 6, the basket 6 advances to the electric furnace together with the carrier truck 5, and one of the cargo handling trucks 10 lifts the basket 6 again (the bottom plate 22 is (Close again) Traveling, returning to the original position, the box 20 is returned to the weighing carriage 3. The loading trolley 10 then removes the hook 16 from the box 20, switches it horizontally, and raises it into a standby state.

It should be noted that the scrap transshipment work described above can be performed by this device (special machine) instead of the existing overhead crane.
In addition to the labor saving of this work, the following advantages were obtained at this factory. That is, a) This work (the distance to move the cargo handling object is very short)
Since the time dedicated to the crane has been reduced, the time available to effectively use the crane has increased due to the large distance traveled and the height difference making it easy for the original functions to be exhibited. B) With this equipment, 40 tons of scrap can be handled at one time, and the productivity can be improved by speeding up the charging of scrap into the electric furnace. C) If this equipment were to be replaced with an overhead crane, a span of about 30 meters and 40
A large crane with a lifting capacity exceeding tons is required and considerable equipment investment is required, but in this respect, the equipment cost can be greatly saved due to the placement of this device.

Although one embodiment has been introduced above, the present invention is not limited to this, and the invention can be implemented as follows, for example. That is, various means can be used as the lifting means for the hooks and hook blocks in the cargo truck, instead of the means including the wire rope (or chain). Since the guide frame prevents the hook block from swinging, even if a mechanism such as a screw shaft (feed screw), a hydraulic cylinder, or a rack and pinion is used as the lifting means, no bending moment is applied to them. .

[0036]

The bulk transfer device of the present invention has the following effects. That is, 1) handling truck in handling the object without the assistance of workers
Since it is possible to hang a hook on a certain cargo handling container and suppress the shaking of the hook and the cargo handling container , a series of operations necessary for cargo handling can be performed by unmanned or extremely few workers.
It can be done reliably and smoothly.

2) It is possible to stably support and move an object to be handled (cargo container) , even if the object is a heavy object, and even if the traveling of the dolly is accompanied by a considerable acceleration. .

3) The operation of moving the loose material in the cargo handling container to the receiving place can also be performed in an unmanned state.
