Description

  The present invention relates to a material conveying device, and more particularly to a material conveying device that can be directly attached to a press facility so that a blank material can be taken out from a stack and pressed regardless of the presence or absence of a destack feeder.

  In the field of metal presses, generally, so-called destack feeders take out blank materials one by one from a stack in which blank materials are stacked, transport them to a press facility, and then press work is performed in the press facility. Is called.

For example, a transfer press is known as such a press facility.
In the transfer press, molds independent of each process are arranged in a single press facility, the blank material is transferred between the processes by a transfer feeder, and the process of each process is continuously performed on the blank material. It is a facility that can.
Moreover, as a destack feeder, since the steel material generally used as a blank material has magnetism, what was equipped with the magnet conveyor which magnetizes and conveys steel materials is known (refer patent document 1 or 2). In such a destack feeder, a steel material can be efficiently conveyed with low energy by using a magnet conveyor.

However, although the transfer press apparatus described in Patent Document 3 can press aluminum material, the transfer press apparatus alone cannot take out the aluminum material from the stack state and carry it into the transfer press apparatus. .
Therefore, in this case, it is necessary to use a destack feeder. However, as described above, since the aluminum material is nonmagnetic, the destack feeder described in Patent Document 1 or 2 including a magnet conveyor can be used. Can not.

It is possible to introduce a new destack feeder for conveying aluminum material, but in this case, there is a disadvantage that the cost becomes extremely high and a new space for installation is required.
In addition, when the steel material is processed instead of the aluminum material after the aluminum material is processed, the destack feeder for conveying the aluminum material is not suitable for conveying the steel material. That is, a load is applied to the conveyance of the steel material, and the conveyance takes time.
Therefore, a destack feeder for conveying aluminum materials has a disadvantage that it is inferior in versatility.

In the press facility P, since the material conveying device 10 itself is interposed between the bolster 2 and the slide 3 of the press facility P, the aluminum material is removed from the stack in the press facility P regardless of the presence or absence of the destack feeder. Can be taken out and pressed.
Therefore, it is not necessary to newly install a destack feeder for aluminum material, and a space different from the press facility P for installing the material conveying apparatus 10 is not required.

  In the press facility P, the material conveying device 10 is positioned on the most upstream side of the respective molds 1a, 1b, 1c, 1d, and 1e, and in series with the respective molds 1a, 1b, 1c, 1d, and 1e. It is arranged to become. For this reason, in the press facility P, the aluminum material carried out from the material conveying device 10 can be efficiently and linearly conveyed to the respective molds 1a, 1b, 1c, 1d, and 1e on the downstream side, and more It is possible to perform press working with the molds 1a, 1b, 1c, 1d, and 1e.

  In the press facility P, the material conveying apparatus 10 removes one of a plurality of molds provided in the existing press facility and is directly attached to the bolster 2 instead of the mold. That is, the material conveying apparatus 10 can be attached to the bolster 2 by a method similar to a method of attaching a conventional mold such as fixing by a clamp at a position where the mold is originally attached.

(A)-(c) of Drawing 2 is an upper surface figure for explaining an example of a method of attaching a material conveyance device instead of a metal mold to a bolster of press equipment, and (d) is a thing of (a). It is a side view.
As shown in FIGS. 2A and 2D, in a general press facility, the bolster 2 is provided with a plurality of linear grooves 2a in a direction perpendicular to the aluminum material conveyance direction.
In the lower mold 1a1, holes are provided in the mold flange portions F on both sides.
The lower mold 1a1 is fixed to the bolster 2 by matching the hole of the mold flange portion F with the groove 2a of the bolster 2 and clamping from above. In addition, the position of the groove 2a of the bolster 2 to which the lower mold 1a1 is attached can be appropriately selected according to the size of the lower mold 1a1.

Next, as shown in FIG. 2 (b), the lower mold 1a1 is removed by releasing it from the clamped state, and as shown in FIG. 2 (c), by the same method as the lower mold 1a1, The material conveying device 10 is fixed to the bolster 2 by clamping.
Thus, the material conveying device 10 is attached to the bolster 2 of the press facility instead of the lower mold 1a1.

  Moreover, since the material conveyance apparatus 10 is attached to the bolster 2 similarly to a metal mold | die, the mounting base of the material conveyance apparatus 10 mentioned later is detachable from the bolster 2. FIG. For this reason, after pressing the aluminum material, when pressing the steel material again, the material conveying device 10 may be removed and the mold may be attached thereto.

In the press facility P, the slide 3 reciprocates in the vertical direction by a drive mechanism such as a crank mechanism (not shown). As a result, the aluminum material is pressed between the upper molds 1a2, 1b2, 1c2, 1d2, and 1e2 and the corresponding lower molds 1a1, 1b1, 1c1, 1d1, and 1e1.
Moreover, conveyance of the aluminum material between adjacent metal mold | die 1a, 1b, 1c, 1d, 1e is performed by the transfer feeder which is not shown in figure.

(A)-(d) of FIG. 3 is explanatory drawing for demonstrating the press work using the press installation with which the material conveying apparatus which concerns on this embodiment was attached.
In the press facility P, the stack S is placed on the material conveying device 10, and the first aluminum material A1 at the top of the stack S is transferred by the material conveying device 10 to a transfer feeding device (not shown). Details of the structure of the material conveying device 10 and delivery to the transfer feeding device will be described later.

As shown to (a) of FIG. 3, a transfer feeder conveys 1st aluminum material A1, and mounts it in the 1st metal mold | die 1a of the downstream of the material conveying apparatus 10. As shown in FIG.
And as shown in FIG.3 (b), the aluminum material A1 is pressed by the 1st metal mold | die 1a. At this time, there is a certain gap between the material conveyance device 10 and the slide 3 so that they do not interfere with each other. That is, the distance T1 from the upper surface of the bolster 2 to the lower surface of the slide 3 at the bottom dead center is larger than the distance T2 from the upper surface of the bolster 2 to the upper surface of the material conveying device 10 (see FIG. 3A). Yes.

Next, the second aluminum material A2 at the top of the stack S (which was under the first aluminum material A1 in the previous stage) is transferred to the transfer feeding device by the material conveying device 10, and is 1st aluminum material A1 pressed from 1 metal mold | die 1a is received by a transfer feeder.
As shown in FIG. 3C, the transfer feeder conveys the first aluminum material A1 and places it on the second mold 1b on the downstream side of the first mold 1a. The material A <b> 2 is transported and placed on the first mold 1 a on the downstream side of the material transport device 10.
Then, as shown in FIG. 3D, the aluminum material A2 is pressed by the first mold 1a, and the aluminum material A1 is pressed by the second mold 1b.

Similarly, the transfer feeding apparatus applies each aluminum material not only to the first mold 1a and the second mold 1b but also to the third mold 1c, the fourth mold 1d, and the fifth mold 1e. It conveys sequentially and press is performed also in each metal mold | die 1c, 1d, 1e.
That is, the aluminum material is taken out one after another by the material conveying device and conveyed to the respective molds 1a, 1b, 1c, 1d, and 1e on the downstream side by the transfer feeding device, and the respective molds 1a, 1b, 1c, 1d, and 1e. Will be pressed.

Returning to FIG. 1, the material conveyance device 10 is used to position the stack S, the lifter 12 that moves the stack S up and down, and the stack S to position the stack S. A plurality of guide pins 13 erected on the mounting table 11, a stacker 14 for sucking and holding the uppermost aluminum material of the stack S and transferring it to a transfer feeder (not shown), and an illustration provided on both sides of the mounting table And a flange portion that does not. In addition, this flange part is for fixing to the bolster 2 instead of the metal mold | die flange part F of the metal mold | die mentioned above, The hole which is not shown in figure for clamping is provided in the said flange part. .
As described above, the material conveying device 10 includes these, and takes out the aluminum materials one by one from the stack S placed on the placing table 11 while being positioned by the guide pins 13 using the stacker 14. Can do.

  In the material conveyance device 10, the mounting table 11 is a box-shaped table for mounting the stack S. Specifically, the mounting table 11 includes an upper surface portion 11a on which the stack S is directly mounted, a lower surface portion 11b attached to the bolster 2, and a side wall portion 11c that connects the upper surface portion 11a and the lower surface portion 11b. .

In the mounting table 11, the lower surface part 11 b is fixed to the bolster 2. Thereby, the upper surface part 11a is also fixed to the bolster 2 through the side wall part 11c.
As described above, the lower surface portion 11 b of the mounting table 11 is attached to the bolster instead of one of the molds of a known press facility, and is detachable from the bolster 2.

In the mounting table 11, the side wall part 11b connects the lower surface part 11b and the upper surface part 11a, and supports the upper surface part 11a.
Here, the mounting table 11 has a space between the upper surface portion 11a and the lower surface portion 11b by including the side wall portion 11b.
In addition, a lifter 12 to be described later is disposed in a space between the upper surface portion 11a and the lower surface portion 11b.

FIG. 4A is a top view schematically showing a mounting table of the material conveying apparatus according to the present embodiment, and FIG. 4B is a top view showing a state in which a stack is mounted thereon.
As shown to (a) of FIG. 4, in the mounting base 11, the upper surface part 11a is provided with the some rectangular insertion hole H so that it may parallel. The insertion hole H is formed so as to correspond to the position and shape of the support portion of the lifter described later.
Thereby, although the lifter 12 described later is disposed below the upper surface portion 11a, the support portion can be protruded above the upper surface portion 11a through the insertion hole H.

In the mounting table 11, a plurality of guide pins 13 are erected on the four peripheral edges of the upper surface portion 11 a.
Here, as shown in FIG. 4B, the stack S is placed on the upper surface portion 11 a of the placement table 11. At this time, the stack S is positioned by bringing the periphery of the stack S into contact with the guide pins 13.

Here, an air blow device (not shown) for blowing high-pressure air to the end surface of the stack S is attached to the guide pin 13. In addition, the blowing method of the high pressure air in an air blow apparatus may be a continuous type or an intermittent type.
In the material conveying device 10, since the air blow device is attached to the guide pin 13, when the uppermost aluminum material of the stack S is lifted, high-pressure air is blown between the aluminum material and the aluminum material immediately below the aluminum material. Can be sprayed. As a result, it is possible to suppress the occurrence of a so-called double blank that simultaneously lifts two aluminum materials.

Returning to FIG. 1, the lifter 12 is accommodated in a box-shaped mounting table 11. The lifter 12 may be any of electric type, hydraulic type, and pneumatic type.
The lifter 12 has a plurality of rectangular parallelepiped support portions 12 a extending in the vertical direction, and the support portions 12 a are inserted into the insertion holes H and are in contact with the lower surface of the stack S. That is, the support portion 12a can be moved up and down while being inserted through the insertion hole H.
Therefore, in the material conveying apparatus 10, by operating the lifter 12, the support portion 12a is brought into contact with the stack S without touching the upper surface portion 11a, and only the stack S is moved up and down directly.

Thus, in the material conveyance apparatus 10, since only the stack S moves up and down, the upper surface portion 11a of the mounting table 11 does not move. That is, the guide pin 13 erected on the upper surface portion 11a and the air blow device attached thereto do not move.
As a result, the stack S moves up and down while maintaining the state of positioning by the guide pins 13.
Further, the lifter 12 raises the stack S by pitch feed by the thickness of the extracted aluminum material, so that the position at which the aluminum material is extracted can be made constant. As a result, the position where the non-moving air blowing device blows the high-pressure air is always between the uppermost aluminum material of the stack S and the aluminum material immediately below it.

The stacker 14 includes a base portion 14a extending in the vertical direction and an arm portion 14b extending in the horizontal direction from the base portion 14a.
Specifically, in the stacker 14, a screw shaft (not shown) is accommodated in a base portion 14a, and an arm portion 14b is connected to a nut attached to the screw shaft. That is, the so-called ball screw mechanism allows the arm portion 14b to move up and down along the longitudinal direction of the base portion 14a while maintaining a horizontal state.
Further, a vacuum cup is attached to the lower surface of the arm portion 14b for adsorbing and holding the aluminum material by negative pressure.
In the material conveying apparatus according to the present embodiment, three stackers 14 are used in parallel (see FIG. 5). These destackers 14 can be driven independently.

FIG. 5 is a partial perspective view for explaining the outline of the transfer feeding device of the press facility to which the material conveying device according to the present embodiment is attached.
As shown in FIG. 5, the transfer feeding device 15 includes a plurality of finger portions 15a that support an aluminum material, and a feed bar 15b to which the plurality of finger portions 15a are fixed. The transfer feeding device includes a finger portion 15a and a feed bar 15b, and the feed bar 15b slides in the longitudinal direction as shown by an arrow, so that an aluminum material can be used for each mold 1a, 1b, 1c, 1d, 1e. Any known transfer feeder can be used as long as it can be conveyed.

FIG. 6 is an explanatory diagram for explaining a method of delivering an aluminum material from the material conveying device according to the present embodiment to the transfer feeding device.
First, as shown in FIG. 6, in the material transport device 10, the arm portion 14 b of the stacker 14 sucks and holds the uppermost aluminum material of the stack S through the vacuum cup.
And the arm part 14b raises and moves along the base part 14a, maintaining the state.

Next, the transfer feeding device 15 moves the feed bar 15b so that the finger portion 15a is positioned between the arm portion 14b and the stack S.
And the arm part 14b moves down along the base part 14a, and delivers an aluminum material to the finger part 15a.
Then, the arm portion 14b is retracted by moving upward along the base portion 14a, and at the same time, the feed bar 15b is moved in the horizontal direction to convey the aluminum material supported by the finger portions 15a. To do.
After that, the arm part 14b moves downward along the base part 14a and sucks and holds the uppermost aluminum material of the next stack S.

In this way, the aluminum material is transferred from the material conveying device 10 to the transfer feeding device 15.
The transfer feeding device 15 that has received the aluminum material sequentially conveys the aluminum material to the respective molds 1a, 1b, 1c, 1d, and 1e on the downstream side in the same manner as a known method.

As a result, in the press facility P, the aluminum material is taken out by the destacker 14 of the material conveying device 10 and transferred to the transfer feeding device 15, and the downstream molds 1 a, 1 b, It is sequentially conveyed to 1c, 1d, and 1e.
Therefore, by incorporating the material conveying device 10 into the existing steel press equipment, the press equipment for aluminum material can be easily obtained.
According to the press facility P, it is possible to easily press the aluminum material.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment.

Moreover, it is not limited to a nonmagnetic material like these, It is also possible to use magnetic materials, such as a steel plate.

  The press equipment P to which the material conveying apparatus 10 according to the present embodiment is attached includes a material conveying apparatus 10, a first mold 1a, a second mold 1b, and a third mold 1c between the bolster 2 and the slide 3. Although the fourth mold 1d and the fifth mold 1e are arranged, the number of molds is not limited to five. That is, the number of molds arranged between the bolster 2 and the slide 3 may be 1 to 4, or 6 or more.

In the press facility P to which the material conveying device 10 according to the present embodiment is attached, the material conveying device 10 is located on the most upstream side of each mold 1a, 1b, 1c, 1d, 1e. It is not necessary to be upstream.
FIGS. 7A and 7B are schematic views illustrating other examples of the installation positions of the material conveyance device when the material conveyance device according to the present embodiment is attached to a press facility.
For example, as shown in FIGS. 7A and 7B, when the pressing is performed in the direction of the arrow from the upstream side to the downstream side, the material conveying device 10 is the second die from the upstream side. It may replace with (refer Fig.7 (a)), and may replace with a 4th metal mold | die from an upstream side (refer Fig.7 (b)). In addition, if the material conveyance apparatus 10 is installed in the most downstream side, subsequent press work cannot be performed.

  In the press facility P to which the material conveying device 10 according to the present embodiment is attached, the mold flange portion F of the mold and the flange portion of the material conveying device 10 are fixed to the bolster 2. It is not limited to this.
