Description

TECHNICAL FIELD The present invention relates to a suspension transfer technology used to transfer a coiled (cylindrical) conveyed object such as a coiled plate or wire. It relates to a hanging support device and a transportation method.

Metal sheets, metal wires, and the like, which are used in various industrial applications, are essential materials in the manufacturing industry, and are produced by specialized manufacturers and delivered to factories all over the country.
When conveying such a metal plate or metal wire, generally, the object to be conveyed such as the metal plate or metal wire is made into a coil shape or a cylindrical shape (hereinafter collectively referred to as a coil shape), and then is conveyed by a crane or the like. be lifted and transported.

2. Description of the Related Art Conventionally, when a coil-shaped conveyed object is suspended by a crane or the like as described above, the suspension work is performed via a lock hanger. Generally, an automatic type and a manual type are used for such a lock hanger. Of these automatic lock hangers, for example, the devices shown in Patent Documents 1 to 5 below are known, and the hooks of the hangers are opened and closed using an actuator, a motor, a cylinder mechanism, or the like as a drive source to convey a coil. A structure that holds things is adopted.

Before the appearance of the above-described automatic key hangers, manual lock hangers such as those exemplified in Patent Document 1 were also used. There is a tendency to avoid this method because it requires a lot of manpower, takes time and effort, and is dangerous for the operator when opening and closing the hook.

However, it cannot be said that the current technology, not limited to the patent documents mentioned above, adequately satisfies the needs of the market, and each of the above methods has the following problems.
In other words, the configuration of the automatic lock hanger including Patent Documents 1 to 5 described above is advantageous in that the risk is certainly reduced and the convenience is improved as compared with the manual type.

However, in the structures shown in these Patent Documents 1 to 5, in addition to the driving source for the lifting operation of the crane, it is necessary to provide a driving source for opening and closing the arm and the hook, and it is inevitable that the device configuration will become bloated. do not have. In addition, these automatic lock hangers require skill to control the operation of the drive source, and require relatively frequent maintenance to maintain their performance.

Needless to say, since many driving sources are required, not only the weight of the device increases but also the manufacturing cost inevitably increases.
As described above, existing technology has not yet realized a lock hanger that is simpler in structure, highly convenient, and less dangerous, and there is still a strong demand for a lock hanger that satisfies such needs. There is a problem that

<Suspension support device 100>
A detailed structure of the hanging support device 100 according to the embodiment of the present invention will be described with appropriate reference to FIGS. 1 to 7. FIG.
The suspension support device 100 of the present embodiment has a function of transporting an object to a desired location by suspending and moving the object by means of a transport arm 40, which will be described later.

The object to be transferred is not particularly limited as long as it can be suspended and supported by the transfer arm 40. For example, the above-described coil-shaped (cylindrical) object to be transferred can be exemplified. The contents of the coil-shaped conveyed product are not limited to the above-described thin metal plate or metal wire material, and include, for example, paper, resin, and other materials suitable for various industrial uses.
In addition, as the object to be conveyed, in addition to a coiled object, any object having a cylindrical shape can be suspended and supported by the conveying arm 40. Therefore, such an object can also be carried. You may apply as a conveyed thing of embodiment.

More specifically, the suspension support device 100 includes at least an arm base 10, a cam member 20, a horizontal frame 30, and a transfer arm 40, as shown in FIG.
The arm base 10 is configured to be movable in the vertical direction (Z direction, gravity direction) by an external lifting device (not shown). Examples of such an external elevating device include various known cranes represented by overhead cranes, jib cranes, and bridge cranes. A known lifting device may be used.

First, the arm base 10 will be described.
As is clear from FIGS. 1, 2 and 5, the arm base 10 is made of a pair of plate members facing each other, and includes an arm connection portion 11, a cam member connection portion 12, an elevator device connection portion 13, and the like. . As the material of the arm base 10, a hard metal material such as known structural steel can be applied. In this embodiment, an octagonal plate member is used, but the plate member is not limited to this shape, and may be another rectangular shape such as a hexagonal shape, or an elliptical shape such as an oval shape that is elongated in the vertical direction.

The arm connecting portion 11 is a portion to which a connecting end portion 42 of a transfer arm 40, which will be described later, is connected. In this embodiment, the transfer arm 40 is configured to be able to turn around the connection end portion 42 as a base point. As more specifically illustrated in FIG. 5B, in the arm connecting portion 11 of the present embodiment, the pivot 11a is inserted into a shaft hole formed in the arm base 10 and fixed with a fixing nut 11b. .

The cam member connecting portion 12 is a portion to which an upper end connecting portion 23 of the cam member 20, which will be described later, is connected. In this embodiment, the positional relationship between the cam member 20 and the arm base 10 in the vertical direction is fixed and connected. Therefore, as illustrated in FIG. 5(c), the cam member connecting portion 12 of the present embodiment employs a configuration in which a plurality of fastening bolts 12a are used to screw them.
As shown in the figure, the cam member 20 may be fixed at the cam member connecting portion 12 via a spacer 12b, but the spacer 12b may be omitted as appropriate.

The lifting device connecting portion 13 is a portion to which an external lifting device such as the crane described above is connected. In this embodiment, since a crane is used as the external lifting device, the structure is such that the hook of the crane is caught. Therefore, as illustrated in FIG. 5A, in the lifting device connecting portion 13 of the present embodiment, the hook shaft 13a is inserted into a shaft hole formed in the arm base 10 and fixed with a fixing nut 13b.

Next, the cam member 20 will be explained.
As is clear from FIGS. 1, 3 and 7, the cam member 20 is a plate-like body provided so as to hang down from the bottom (vertically downward side) of the arm base 10. It has the function of descending or ascending along
More specifically, the cam member 20 of the present embodiment is made of a metal plate material that is shaped like a key when viewed from above. Although the specific material of the cam member 20 is not particularly limited, it may be made of the same material as the above-described arm base 10 from the viewpoint of ensuring strength to some extent.

As shown in FIG. 7, such a cam member 20 has an inclined region 20a, a pin fixing region 20b, and a pin retreating region 20c in order from the tip side of the key-like shape. When the cam member 20 is used, the tip end of the key-like shape is arranged on the lower side in the vertical direction. Therefore, when the cam member 20 is used in this embodiment, the inclined area 20a, the pin It can also be said that it has the fixed area 20b and the pin retraction area 20c.

Furthermore, in other words, the “inclined region 20a” in the present embodiment can be said to be a region corresponding to a slope that intersects the vertical direction so as to widen from the lower end (tip) of the key-shaped side surface. The "pin fixing region 20b" means that the reference length from the fixing portion 30a of the rotating cam pin 33 in the side surface of the cam member 20 is shorter than the pin length from the fixing portion 30a to the tip 33a of the rotating cam pin 33. It can be said that it is an area. Further, it can also be said that the "pin retraction area 20c" is an area in which the above-described reference length is longer than the above-described pin length.

As shown in FIG. 7, a first stepped portion 21 is formed at the boundary between the inclined region 20a and the pin fixing region 20b so that the tip of a rotating cam pin 33, which will be described later, can climb over. A second stepped portion 22 is also formed at the boundary between the pin fixing region 20b and the pin retracting region 20c so that the tip of the rotating cam pin 33 can get over it. Functions of the first stepped portion 21 and the second stepped portion 22 will be described in detail later.
Further, as shown in FIG. 1, the cam member 20 of this embodiment may have a guide wall 24 that guides the movement of the cam member 20 in the vertical direction. Typically, it is preferable that a pair of guide walls 24 be fixedly installed on the upper surface of the horizontal frame 30 so as to sandwich the cam member 20 therebetween. As a result, the opening and closing operations of the transfer arms 40 positioned on both sides of the cam member 20 in the vertical direction accompanying the downward movement of the arm base 10 are performed smoothly so as to be uniformly opened and closed.

Further, as shown in FIG. 7, in this embodiment, approximately half of the cam member 20 in the longitudinal direction is the inclined region 20a, the pin fixing region 20b, and the pin retracting region 20c. is arranged with the above-described upper end connecting portion 23 . The upper end connecting portion 23 is formed with screw holes into which the above-described fastening bolts 12a are inserted, and eight screw holes are formed in this embodiment. Note that the number of screw holes can be appropriately adjusted from the viewpoint of strength, cost, etc., and is not limited to eight screw holes as employed in this embodiment.

Next, the horizontal frame 30 will be explained.
As is clear from FIGS. 1 to 4 and 6, the horizontal frame 30 has a horizontal hole 31 extending in the horizontal direction. direction) is provided. As is clear from FIG. 2 and the like, the horizontal frame 30 of the present embodiment is configured in such a manner that a pair of plate members having concave cross sections face each other at their bottoms. As the material of such horizontal frame 30, for example, various metal materials such as steel similar to that of the above-described arm base 10 can be applied.

The horizontal frame 30 of this embodiment has a function of regulating the opening and closing operation of the transfer arm 40, which will be described later, and includes a horizontal hole 31, a regulation means 32, a rotating cam pin 33, a mounting portion 34, a side guide 35, and the like. consists of In other words, in the hanging support device 100 of the present embodiment, the rotating cam pin 33 regulates the vertical movement of the cam member 20, and the horizontal hole 31 regulates the movement of the projecting member 41 as will be described later. , the opening of the transfer arm 40 is maintained.

For example, as shown in FIG. 1, the horizontal holes 31 are formed near both ends of the horizontal frame 30 so as to correspond to the projecting members 41 of the transfer arm 40 . A protruding member 41 is movably arranged in the horizontal hole 31, so that the transfer arm 40 can be appropriately rotated with the arm base 10 as a base point. In the present embodiment, the two transfer arms 40 are arranged symmetrically with respect to the center of the horizontal frame 30. However, when the suspension support device 100 is composed of one transfer arm 40, the horizontal hole 31 is also the same. It is only necessary to form one according to the

The regulating means 32 has a function of regulating the posture of the rotary cam pin 33 so that the rotary cam pin 33, which will be described later, faces a predetermined direction as a reference state (a state in which no external load is applied). More specifically, as shown in FIG. 4(a), the restricting means 32 of this embodiment includes one end 32a connected to the rear end 33c of the rotating cam pin 33, and the other end 32a connected to the fixing portion 30b of the horizontal frame 30. end 32b. Then, the restricting means 32 pulls the rear end 33c of the rotary cam pin 33 and urges the transfer arm 40 in the opening direction.

As described above, the restricting means 32 in this embodiment includes an elastic member having one end 32 a fixed to the horizontal frame 33 and the other end 32 b connected to the rotating cam pin 33 . Such an elastic member is not particularly limited as long as it can urge the rotating cam pin 33 in a desired direction, but a known member such as a spring or rubber may be used.

The rotating cam pin 33 is a member that has both the function of restricting the movement of the cam member 20 in the vertical direction and the function of adjusting the opening degree of the transfer arm 40 . More specifically, the rotary cam pin 33 in this embodiment is installed in the horizontal frame 30 by rotatably connecting the rotary shaft portion 33b to the fixed portion 30a of the horizontal frame 30, as shown in FIG. ing. Note that it is preferable that a plurality (two in this example) of the rotating cam pins 33 are arranged so as to sandwich the cam member 20 in correspondence with the number of the transport arms 40 as in the present embodiment.

Further, as shown in FIG. 4B, the fixing point 30a of the rotary cam pin 33 on the horizontal frame 30 and the fixing point 30b of the restricting means 32 on the horizontal frame 30 have substantially the same height in the vertical direction. Preferably. As a result, when the restricting means 32 pulls the rear end 33c of the rotary cam pin 33, the leading end 33a of the rotary cam pin 33 can assume a posture along the horizontal direction (Y direction).
As is clear from FIG. 4(b), the rotary cam pin 33 is rotatable around a rotary shaft portion 33b, and its tip 33a contacts the side surface of the vertically movable cam member 20. , the first stepped portion 21 and the second stepped portion 22, and the like.

The mounting portion 34 is a portion that comes into contact with the transported object when the suspension support device 100 is lowered onto the transported object. In other words, the placement section 34 has a function as a support base when the hanging support device 100 is landed on the transported object. The material of the mounting portion 34 is not particularly limited. For example, in addition to the metal materials described above, hard resin or the like may be used as long as the strength can be ensured. Further, the installation position of the mounting portion 34 on the bottom surface of the horizontal frame 30 is not limited to the installation position shown in the drawing, and may be changed as appropriate according to the width of the object to be transported.

Further, the placing section 34 of the present embodiment may be provided with a known elastic means such as rubber or a spring, thereby suppressing unintentional bouncing or tilting when landing on the carried object. be. Further, the bottom surface of the mounting portion 34 that contacts the transferred object may be covered with various known soft materials such as a rubber sheet. As a result, damage to the transported object can be suppressed when the transported object lands on the transported object.

The side guide 35 has a function of regulating the position of the transported object when the transporting arm 40 supports the transported object. More specifically, a plurality of side guides 35 (two in this example) are installed on the bottom surface of the horizontal frame 30 so as to correspond to the position of the transported object during transportation. The material of the side guides 35 is not particularly limited and can be exemplified by a metal material or a resin material.
Note that the installation position of the side guide 35 on the bottom surface of the horizontal frame 30 is not limited to the installation position shown in the drawing, and may be changed as appropriate according to the width of the object to be transported, similarly to the mounting portion 34 described above. .

Next, the transport arm 40 will be described.
As is clear from FIGS. 1 to 3 and 6, the transfer arm 40 is rotatable with the above-described arm base 10 as a base point, and is arranged in the horizontal hole 31 in the horizontal direction (Y direction, in which the horizontal frame 30 extends). direction) is provided.
More specifically, the transfer arm 40 in this embodiment includes a projecting member 41, an arm base connection portion 42, a hook body 43, and the like.

The protruding member 41 is a portion protruding in the ±X direction from the main surface of the transfer arm 40, as shown in FIGS. 3 and 6A. More specifically, as exemplified in FIG. 6A, the projecting member 41 includes a projecting shaft 41a passing through a circular hole formed in the transfer arm 40, and an end portion of the projecting shaft 41a. and a fixing nut 41b for suppressing the slipping and falling.

As shown in the figure, a spacer 31h having a horizontal hole similar to the horizontal hole 31 may be interposed between the fixing nut 41b and the horizontal frame 30. In this case, the spacer 31h holds the fixing bolt 31i. It is fixed to the horizontal frame 30 via.
With the structure described above, the projecting member 41 of this embodiment is configured to be movable in the horizontal direction (Y direction) in the lateral hole 31 .

As illustrated in FIGS. 3 and 5B, the arm base connecting portion 42 is a circular hole formed near the end of the transfer arm 40 on the arm base 10 side. When assembling the hanging support device 100, the swivel shaft 11a passing through the shaft hole of the arm base 10 is inserted into the arm base connecting portion 42 as the circular hole and fixed via the fixing nut 11b.

The hook body 43 is a hook-shaped structure with a bent tip that is connected to the end of the transfer arm 40 opposite to the arm base connecting portion 42 . More specifically, as shown in FIG. 6B, the hook body 43 is a pair of hook-shaped plate members arranged to face each other so as to sandwich the transfer arm 40. It is fixed via a fastening screw 43a passing through the hole and a fastening screw hole 43b.

Although there is no particular limitation on the specific material of the hook body 43, for example, the same material as that of the above-described horizontal frame 30 can be exemplified. Moreover, the portion of the hook body 43 that comes into contact with the object to be conveyed may be covered with various known soft materials such as a rubber sheet.
As a result, it is possible to prevent the transported object from being damaged when hooking the transported object with the hook body 43 .

In this manner, as shown in FIG. 3, a plurality (two in this example) of the transport arms 40 in the present embodiment are arranged symmetrically with respect to the center CNT of the horizontal frame 30, and the horizontal holes 31 Also, it is desirable that a plurality (two in this example) of the projection members 41 are arranged corresponding to the number of the transport arms 40 .

However, the present invention is not limited to this form, and for example, a form in which the transfer arm 40 is installed on either side of the center CNT of the horizontal frame 30 so as to be cantilevered may be employed. In this case, one horizontal hole 31 and one protruding member 41 are also provided.

<Method of Conveying Object Using Hanging Support Tool 100>
Next, with reference to FIGS. 8 to 14 as appropriate, a method for transporting an object to be transported according to the present embodiment will be described. In the conveying method of the conveyed object according to the present embodiment, the conveying object is conveyed according to the positional relationship between the tip 33a of the rotating cam pin 33 and each region of the cam member 20 (inclined region 20a, pin fixing region 20b, pin retreating region 20c). The main feature is that the opening degree of the arm 40 changes.
Hereinafter, as an example of the conveyed object, the coil-shaped conveyed object P having a circular hole formed at the center thereof will be taken as an example and the description will be continued. Also, for simplification of explanation, the illustration of the spacer 31h covering the lateral hole 31 is omitted. However, in this embodiment, since the hole shape of the spacer 31h is smaller than the hole shape of the horizontal hole 31, it should be noted that the moving range of the projecting member 41 in the Y direction is substantially defined by the spacer 31h.

First, FIG. 8 shows a flowchart relating to a method for transporting a transported object using the suspension support device 100 according to the present embodiment.
First, in step 1, the hanging support device 100 of the present embodiment is moved to the object to be transferred. More specifically, for example, an external elevating device such as a crane lifts the suspension supporting device 100 via the elevating device connecting portion 13 and moves it under the transported object.

At this time, in the hanging support device 100, as shown in FIG. The transfer arm 40 is moved in an open state. In other words, this is when the tip 33a of the rotating cam pin 33 is positioned in the pin fixing region 20b. It is in the "first posture" that prohibits the cam member 20 from moving.

Therefore, the carrier arm 40 is also in a fixed posture (opened state), and in this state, the suspension support device 100 can be freely moved to other places.
In this embodiment, the degree of opening of the transfer arm 40 when the rotary cam pin 33 is in the "first posture" is defined as a "first degree of opening state".

Next, in step 2, after the hanging support device 100 is placed on the object to be conveyed, the cam member 20 is further lowered to release the movement restriction of the cam member 20 by the rotating cam pin 33 .
At this time, as shown in FIG. 10 , in the hanging support device 100 , once the mounting portion 34 of the hanging support device 100 lands on the transported object, after that, the cam member 20 is moved to the horizontal frame 30 . relatively lower. At this time, the degree of opening of the transfer arm 40 is greater than the "first degree of opening state" described above.

Then, as the cam member 20 descends, the tip 33a of the rotating cam pin 33 climbs over the second stepped portion 22 (see FIG. 4), and the tip 33a of the rotating cam pin 33 transitions to the pin retraction area 20c. That is, as shown in FIG. 11, when the leading end 33a of the rotary cam pin 33 is positioned in the pin retraction region 20c, the rotary cam pin 33 assumes a posture along the horizontal direction so as not to hinder the movement of the cam member 20. Posture”. In step 2, the projecting member 41 of the transfer arm 40 is positioned at the outermost end side of the horizontal hole 31 .
In other words, when the rotary cam pin 33 is in the above-described "second posture", the protruding member 41 is located in the horizontal hole 31 at the position farthest from the center of the horizontal frame 30 (on the outer end side). At this time, the transport arm 40 is in a state opened more than the "first degree of opening state".

Next, in step 3, the arm base 10 is lifted and the transport arm 40 hooks the object to be transported. At this time, as shown in FIG. 12, in the hanging support device 100, the arm base 10 rises relative to the horizontal frame 30 together with the cam member 20 while the horizontal frame 30 remains placed on the object to be conveyed. . As the arm base 10 rises in this way, the projecting member 41 of the transfer arm 40 moves in the lateral hole 31 toward the inner end side (the side near the center of the horizontal frame 30), and the transfer arm 40 is covered. Approach the transported object.

At this time, as the cam member 20 rises, the tip 33a of the rotating cam pin 33 continuously climbs over the second stepped portion 22 and the first stepped portion 21 (see FIG. 4), so that the tip 33a of the rotating cam pin 33 The inclined area 20a is reached. That is, since the rotating cam pin 33 is in the horizontal position in step 2, the rotating cam pin 33 can be easily moved to each of the cam members 20 without excessive resistance while receiving the pulling force of the restricting means 32 thereafter. It is possible to climb over the stepped part.

After that, the arm base 10 is lifted in a state in which the rotating cam pin 33 does not restrict the vertical movement of the cam member 20, and the conveying arm 40 hooks the coil-shaped article to be conveyed. Thus, even when the tip 33a of the rotating cam pin 33 is positioned in the inclined region 20a, the rotating cam pin 33 assumes a posture along the horizontal direction and is in a "second posture" that does not hinder the movement of the cam member 20. there is
In other words, when the rotating cam pin 33 is in the above-described "second posture" and the protruding member 41 is positioned closest to the center side (inner end side) of the horizontal frame 30 in the horizontal hole 31, the conveying arm 40 is positioned as described above. It can be said that it is in a closed state than the "first opening state" of .

Subsequently, in step 4, the hooked coil-shaped conveyed article is lifted via the hanging support device 100. As shown in FIG. That is, as shown in FIG. 13, when the transfer arm 40 completes the hooking of the object to be transferred, the relative rise of the arm base 10 with respect to the horizontal frame 30 stops. Lift the load.
Next, in step 5, the transport arm 40 suspends and supports the transported object as described above, and moves the transported object to the destination.
As described above, in this embodiment, after the coil-shaped transported product is hooked by the transport arm 40, the coiled transported product is lifted by the suspension supporting device 100 and transported to a desired destination.

Then, from step 6 onwards, the coil-shaped conveyed goods are loaded and unloaded.
That is, first, in step 6, the suspension supporting device 100 is lowered at the target location to place the object to be conveyed on the ground. More specifically, for example, when the above-described crane is used, the crane places the transported object through the suspension support device 100 .

Next, in step 7, the cam member 20 is further lowered to restrict its movement. More specifically, as shown in FIG. 14, by further lowering the cam member 20 by a predetermined amount with respect to the horizontal frame 30 after the object to be conveyed has landed, the tip 33a of the rotating cam pin 33 is moved to the first position. It climbs over the first step portion 21 and is positioned in the pin fixing region 20b. In other words, it returns to the state shown in FIG. 9 via the state shown in FIG. state will be maintained.
Finally, in step 8, the hanging support device 100 is lifted by a crane or the like and withdrawn from the transported object. This completes the work of transporting the transported object to the desired destination.

According to the present embodiment described above, the opening/closing operation of the transport arm 40 can be substantially combined with the lifting/lowering operation of the object to be transported. , it is possible to realize a low-cost hanging support device 100 in which the enlargement of the device configuration is suppressed.
Furthermore, since the number of drive sources for driving the device is reduced, not only is the weight of the device reduced, but maintenance frequency does not increase, and the operator can operate the device relatively safely with a simple operation. becomes possible.

The above-described embodiment can be modified in various ways without departing from the scope of the present invention, such as combining each embodiment.

As described above, the hanging support device and the transportation method using the same of the present invention are suitable for easily and safely transporting an object to be transported using a smaller number of power sources, and can be carried by a relatively small number of people. It is particularly suitable for transportation work in the factory and transportation work in various factories.
