Description

  The present invention relates to a plate material separating device and a plate material separating method, and more particularly to a plate material separating device and a plate material separating method capable of taking out plate materials such as metal plates stacked in the vertical direction one by one.

  Conventionally, metal products (for example, parts of an automobile body) have a blanking process for cutting metal plates into a predetermined length, a metal plate stacking process for stacking the cut metal plates in the vertical direction, Among these, the metal plate is manufactured through a metal plate extracting step of taking out the uppermost metal plate and a forming step of forming the extracted metal plate by pressing or the like.

  In general, when metal plates are stacked in the vertical direction, the metal plates tend to adhere to each other due to the weight of the metal plates themselves or rust preventive oil applied to the metal plates. For this reason, when the uppermost metal plate is taken out in the metal plate taking out step, the other metal plate (second metal plate from the top) adjacent to the metal plate is taken out at the same time and used in the forming step. There is a problem that a plurality of metal plates are thrown into an apparatus (for example, a press machine).

  Therefore, a technique has been proposed in which a concavo-convex forming step for forming concavo-convex portions at the end of the metal plate is performed before the metal plate stacking step, and air is blown to the end of the metal plate in the subsequent metal plate removing step. (See Patent Document 1).

  According to such a technique, when the metal plates are stacked in the metal plate stacking step, a slight gap is formed on the end portion side between the upper and lower metal plates due to the unevenness. When air is blown into the gap formed between the uppermost metal plate and the second metal plate from the top in the metal plate extraction step, an air film (space) can be formed between these metal plates. . That is, according to the technique described in Patent Document 1, since the upper and lower metal plates are separated from each other by the air film, when the uppermost metal plate is taken out, other metal plates are taken out at the same time. It is possible to suppress.

No. 07-110722

  However, in the technique described in Patent Document 1, when air is blown into the gap, the air often leaks outside without entering between the upper and lower two metal plates. That is, in the technique described in Patent Document 1, unless a relatively large amount of air (air that enters between metal plates and air that leaks out) is blown into the gap, an air film (between two upper and lower metal plates ( There is a problem that the space) cannot be formed, that is, the uppermost metal plate cannot be separated from the second metal plate from the top depending on the amount and position of air blowing.

  In general, when air is blown out (injected) vigorously from a nozzle, a relatively loud sound (noise) is generated. For this reason, in the technique described in Patent Document 1, there is a problem that a large amount of noise is generated by blowing a large amount of air as described above.

  Furthermore, in the technique described in Patent Document 1, since the unevenness protrudes in the stacking direction from the surface of the metal plate, when the metal plate is stacked in the vertical direction, the stacking height becomes high, the stacking place, etc. There was also a problem that some metal plates could not be stacked.

  Moreover, in the technique described in Patent Document 1, since the unevenness is formed on the end side of the metal plate, the metal plates cannot be stacked in parallel and horizontally, and many metal plates are stacked. There is a problem that not only can not be stacked, but also can not be stacked in order.

  The present invention has been made in order to solve the above inconveniences, and an object of the present invention is to separate plate materials that can reliably take out stacked plate materials one by one and can stack many plate materials in an orderly manner. An object is to provide an apparatus and a plate material separation method.

  According to the plate material separating device of the present invention, the plate material separating device for separating the uppermost plate material from the other plate materials adjacent to the uppermost plate material among the plate materials stacked in the vertical direction. An insertion means that can be inserted from above into a through-hole that penetrates in the thickness direction formed in the uppermost plate material at a position different from the other plate material, This is solved by forming a gap between the uppermost plate member and the other plate member by pressing the upper surface of the other plate member downward through the hole.

  Further, according to the plate material separation method of the present invention, the problem is that the through hole is formed after the through hole forming step of forming a through hole penetrating the plate material in the thickness direction, and the through hole forming step. After performing the plate material stacking step of stacking the plate materials in the vertical direction and the plate material stacking step, among the stacked plate materials, the uppermost plate material is adjacent to the uppermost plate material A plate material separating step for separating from the plate material, and the through hole is located at a different position between the uppermost plate material and the other plate material in a state where the plate materials are stacked in the plate material stacking step. In the plate material separating step, an insertion means is inserted into the through hole formed in the uppermost plate material, and the upper surface of the other plate material is pressed downward by the insertion means, whereby the uppermost plate material is separated. Between the plate and the other plate It is solved from to include a gap forming a clearance.

  In any of the above configurations, since the plate material is only formed with a through-hole penetrating in the plate thickness direction, when the plate material is stacked in the vertical direction, the plate materials can be brought into close contact with each other. For this reason, according to the said structure, even if it is a case where many board | plate materials are piled up, it can pile up orderly, restraining stacking height.

  In the above configuration, when the other plate member is pressed by the insertion means inserted into the through hole of the uppermost plate member, a gap is formed between these plate members (the uppermost plate member and the other plate member). It has come to be. For example, such pressing can be performed by moving only the uppermost plate member upward in a state where the insertion means is in contact with the upper surface of another plate member. In such a case, if the uppermost plate material is moved upward, the other plate material is forcibly separated (peeled) from the uppermost plate material, so that when removing the uppermost plate material, the other plate material is also removed at the same time. Can be eliminated.

  Moreover, in the above-described configuration, as described above, the uppermost plate material is separated from the other plate material by pressing the other plate material by the insertion means, and therefore, for example, fluid (for example, compressed air) is supplied. By spraying, compared to a system in which the upper and lower two metal plates are separated from each other, there is an advantage that noise is less likely to be generated and the facility can be simplified.

  As described above, according to the plate material separating apparatus and the plate material separating method according to the present invention, a large number of plate materials can be stacked orderly with a simple configuration, and the plate materials can be reliably taken out one by one.

As shown in FIG.1 and FIG.3, in the metal plate cutting process B, the metal plate cutting apparatus 10 is used to form a through hole 1a penetrating in the plate thickness direction in the metal plate 1, and the metal plate 1 is Cutting is performed in a direction (hereinafter referred to as “orthogonal direction”) orthogonal to the feed direction (hereinafter simply referred to as “feed direction”). In addition, the said through-hole 1a can be formed in shapes, such as a substantially cylindrical shape, a substantially elliptic cylinder shape, and a substantially rectangular parallelepiped shape. Moreover, the operation | work which forms the through-hole 1a in the said metal plate 1 corresponds to the "through-hole formation process" as described in a claim.

  As will be described in detail later, in the present embodiment, the cutting of the metal plate 1 and the formation of the through hole 1a are substantially performed by the elevating member 11 having the first cutting member 12 and the first through hole forming member 13 being lowered. It is comprised so that it may be performed simultaneously. Moreover, in this embodiment, the said raising / lowering member 11 descend | falls at the timing when the length of the cutting direction of the cut | disconnected metal plate 1 becomes substantially the same.

  As shown in FIG. 3, the metal plate cutting apparatus 10 has a work table 16 having a work surface 16 </ b> A capable of moving the metal plate 1 in the feed direction, and moves up and down with respect to the work table 16. The elevating member 11 is capable of.

  The lifting member 11 is provided with a first cutting member 12 and a first through hole forming member 13 so as to protrude from the bottom surface. On the other hand, the work table 16 is provided with a second cutting member 17 and a second through hole forming member 18. In the present embodiment, the first cutting member 12 and the second cutting member 17 are used as members for cutting the metal plate 1, and the first through-hole forming member 13 and the second cutting member are used as members for forming the through-hole 1a. Each of the through-hole forming members 18 is employed.

  Both the first cutting member 12 and the second cutting member 17 are formed of a metal member. The first cutting member 12 extends in the orthogonal direction on the feed direction side of the elevating member 11. The second cutting member 17 has a continuous surface 17 </ b> A continuous with the work surface 16 </ b> A of the work table 16, and extends in the orthogonal direction on the feed direction side of the work table 16.

The first cutting member 12 is located at the lowest position where the elevating member 11 is most lowered, and the side surface on the side opposite to the feeding direction (hereinafter referred to as “counter feed direction”) is the second cutting member. It contacts the side surface of the member 17 on the feed direction side (see FIG. 3B). The metal plate 1 is cut when the elevating member 11 is moved to the lowest position (when the first cutting member 12 and the second cutting member 17 are in contact).
In the present embodiment, when the feed roller 7 (see FIG. 1) is driven and the metal plate 1 is moved to a position where the metal plate 1 is cut, the drive of the feed roller 7 and the conveyer 19 is temporarily stopped. It is comprised so that the downward movement of the raising / lowering member 11 may be started. On the other hand, when the elevating member 11 located at the lowest position moves to the highest ascending position at which the elevating member 11 rises most, for example, the feed roller 7 and the transport conveyor 19 that have been stopped so far are driven. The movement of the metal plate 1 in the feeding direction is resumed.

  The first through-hole forming member 13 is made of a substantially bar-shaped metal member, and a plurality of (two in the present embodiment) are provided at a predetermined interval in the feed direction. The first through hole forming members 13 </ b> A and 13 </ b> B project downward from the bottom surface of the elevating member 11 and are configured to advance and retreat in the vertical direction with respect to the elevating member 11 as the elevating member 11 moves up and down. Yes.

  When one of the first through hole forming members 13 </ b> A and 13 </ b> B is located at the first position that protrudes most downward from the bottom surface of the lifting member 11, the other is slightly below the bottom surface of the lifting member 11. It is located in the 2nd position which protrudes. Further, the first through hole forming members 13A and 13B are configured to be alternately advanced and retracted by a power source (not shown) such as a motor each time the elevating member 11 moves from the lowest position to the highest position. Has been.

  For example, the first through hole forming member 13A on the feed direction side and the first through hole forming member 13B on the counter feed direction side are held in the first position and the second position, respectively (see FIG. 3 (a) and FIG. 3 (b)), when the elevating member 11 moves from the lowest position to the highest position, the first through hole forming member 13A is raised and held at the second position, and the first The through hole forming member 13B is lowered and held at the first position (see FIG. 3C). Thereafter, when the elevating member 11 moves again from the lowest position to the highest position, the first through hole forming member 13A is lowered and held at the first position, and the first through hole forming member 13B is raised. And is held in the second position.

  Similar to the first through hole forming member 13, the second through hole forming member 18 is formed of a metal member. The second through-hole forming member 18 has a continuous surface 18A that is continuous with the work surface 16A of the work table 16, and a hole 18a and a hole 18b are formed at predetermined positions on the continuous surface 18A.

  When the elevating member 11 moves to the lowest lowered position, the first through hole forming member 13A (or the first through hole forming member 13B) located at the first position is inserted into the hole 18a (or the hole 18b). It has become so.

  Thus, in this embodiment, when the elevating member 11 moves to the lowest position, the through-hole 1a is formed at a predetermined position of the metal plate 1, the metal plate 1 is cut, and the elevating member 11 is The first through hole forming member 13 </ b> A and the first through hole forming member 13 </ b> B are configured to advance and retract alternately each time it moves to the highest position. That is, each time the metal plate 1 is cut, the through hole 1a is formed at a different position by either the first through hole forming member 13A or the first through hole forming member 13B.

Next, a metal plate stacking step C that is the next step of the metal plate cutting step B will be described with reference to FIGS. 1 and 4.
As shown in FIG. 1, in the metal plate stacking step C, the metal plate 1 cut by performing the metal plate cutting step B which is the previous step is stored in a stocker 21.

  Specifically, the metal plate 1 cut in the metal plate cutting processing step B is moved toward the stocker 21 by driving of the conveyer 19, and when the metal plate 1 moves to a predetermined position, by its own weight or the like. And stored in the stocker 21. Further, the metal plates 1 are sequentially conveyed by driving the conveyance conveyor 19 and are stacked in the vertical direction in a state where the metal plates 1 are in contact with or close to the inner wall surface 21a on the feeding direction side of the stocker 21.

  In the present embodiment, the through holes 1a formed in the metal plate 1 are alternately shifted in the vertical direction in a state where a plurality of metal plates 1 are stored in the stocker 21 (FIG. 4).

  Next, the metal plate separation step D, which is the next step of the metal plate stacking step C, will be described with reference to FIGS.

  As shown in FIG. 1, FIG. 2 and FIG. 4, the metal plate separating step D includes a gap forming step D-1 and a metal plate removing step D-2 which is the next step of the gap forming step D-1. Yes. In the gap forming step D-1 and the metal plate extracting step D-2, these operations are performed by using the metal plate separating device 30. In addition, the said gap formation process D-1, the metal plate extraction process D-2, and the metal plate separation apparatus 30 are respectively the "gap formation process" and the "plate material extraction process" described in the claims. And “plate material separating device”.

  In the gap forming step D- 1, an operation of forming a gap (space) between the uppermost metal plate 1 and the second metal plate 1 from the top stored in the stocker 21 is performed. In the metal plate extraction step D-2, the uppermost metal plate 1 is used as an apparatus such as a press machine (hereinafter referred to as “metal plate forming device”, not shown) used in the next metal plate forming step E. Carry out transport work. The uppermost metal plate 1 and the second metal plate 1 from the top correspond to the “uppermost plate material” and the “other plate material” recited in the claims, respectively.

  As shown in FIGS. 1 and 4, the metal plate separating apparatus 30 includes a moving member 31 that is provided above the stocker 21 and can move in the vertical direction and the like. The moving member 31 is moved by driving of a driving device (not shown).

  The moving member 31 includes a plurality of (two in the feed direction side and counter feed direction side) insertion members 32 that can be inserted into the through-holes 1a formed in the uppermost metal plate 1. A plurality of adsorbing members 37 that adsorb on the upper surface of the uppermost metal plate 1 are provided. The insertion member 32 and the suction member 37 are provided so as to protrude from the bottom plate of the moving member 31. The insertion member 32 and the moving member 31 to which the adsorption member 37 is attached correspond to “inserting means” and “plate material moving means” recited in the claims.

  The insertion member 32 is made of, for example, a metal member, and includes a substantially cylindrical tubular member 33 fixed to the moving member 31 and a substantially rod-shaped rod member 34 provided in the tubular member 33. Yes.

  The cylindrical member 33 is fixed to the bottom plate of the moving member 31 by welding or the like at the peripheral edge of the opening of the through hole 31a while being inserted into the through hole 31a formed in the bottom plate of the moving member 31. The rod member 34 has a lower end formed in a substantially arc shape and is slidable along the inner peripheral surface of the cylindrical member 33.

  A spring member (for example, a compression coil spring) 35 that biases the rod member 34 downward is installed on the outer periphery of each of the cylindrical member 33 and the rod member 34 in a state where they are assembled.

  The insertion member 32 (bar member 34) on the feed direction side and the insertion member 32 (bar member 34) on the counter feed direction side are formed on the uppermost metal plate 1 when the moving member 31 is lowered. The through hole 1a on the feed direction side and the through hole 1a on the counter feed direction side are disposed at positions where they can enter from above.

In the present embodiment, the metal plate 1 is configured to be stacked in contact with or close to the inner wall surface 21a on the feeding direction side of the stocker 21 (see FIG. 1). That is, in the present embodiment, the metal plates 1 can be stacked with both end portions in the feeding direction of the metal plates 1 being substantially aligned in the vertical direction.
Here, generally, the coil-shaped metal plate 1 used in the present embodiment often has non-uniform lengths in the orthogonal direction. In such a case, it is difficult to stack the metal plates 1 at both ends in the orthogonal direction of the metal plate 1 in a state of being aligned in the vertical direction, unlike both ends in the feed direction. That is, when such metal plates 1 are stacked in the stocker 21, there is a possibility that the positions of the through holes 1 a formed in the metal plate 1 are greatly shifted in the orthogonal direction, that is, when the moving member 31 is lowered, the insertion member 32. However, there is a possibility that it is not inserted into the through hole 1a formed in the uppermost metal plate 1.
In such a case, in consideration of the displacement of the through hole 1a, it is preferable that the shape of the through hole 1a in a plan view is not a substantially circular shape but a long hole extending in an orthogonal direction.

Next, the adsorption member 37 will be described with reference to FIG.
As shown in FIG. 4, the adsorbing member 37 includes a pipe member 38 that is fixed so as to penetrate the moving member 31 in the vertical direction, and a bellows-like pad member 39 that is attached to the lower end portion of the pipe member 38. Have. In the present embodiment, the suction members 37 are arranged at predetermined positions on both sides in the feeding direction of the insertion members 32 and 32, and are arranged at appropriate positions.

  The pipe member 38 has a flow path 38 a capable of sucking air, and an upper end portion of the pipe member 38 is connected to the pipe line 52. The pipe line 52 connected to the pipe member 38 is connected to a suction device (for example, a vacuum generator, not shown) that sucks air.

  The pad member 39 is formed in a hollow substantially truncated cone shape, and has an opening 39a and an opening 39b on the top side and the bottom side, respectively. The pad member 39 has a top (opening 39a) side connected to the lower end of the pipe member 38, sucks air from the opening 39b, and discharges the sucked air through the flow path 38a of the pipe member 38. .

  In the pad member 39, when the moving member 31 is lowered, the rod member 34 of one insertion member 32 (the insertion member on the counter feed direction side in the example shown in FIG. 4) contacts the second metal plate 1 from the top. Almost at the same time, it is arranged at a height position so as to contact the uppermost metal plate 1.

Next, the work performed in the metal plate separation step D will be described with reference to FIG.
The metal plate separating step D in the present embodiment is started at a predetermined timing, for example, a timing at which the driving of the transport conveyor 19 (see FIG. 1) is temporarily stopped. As described above, the metal plate separation step D is configured to perform the metal plate extraction step D-2 after the gap formation step D-1.

  The work in the metal plate extraction process D starts from moving (lowering) the moving member 31 toward the metal plate 1 stored in the stocker 21 when the predetermined timing is reached (FIG. 4A and FIG. 4). (See (b)).

  As shown in FIGS. 4A and 4B, when the moving member 31 is lowered by a predetermined distance, the rod member 34 of one insertion member 32 (the insertion member on the counter feed direction side in the example shown in FIG. 4) is It is inserted into a through hole 1 a formed in the upper metal plate 1.

  The moving member 31 is lowered to a position where the bar member 34 of the one insertion member 32 contacts the upper surface of the second metal plate 1 from the top through the through hole 1a formed in the uppermost metal plate 1. The movement is stopped when it is done.

  In this state, the pad member 39 (adsorption member 37) abuts on the upper surface of the uppermost metal plate 1, and the rod member of the other insertion member (in the example shown in FIG. 4, the insertion member on the feed direction side) 32. 34 abuts on the upper surface of the uppermost metal plate 1 with the distance in the vertical direction shortened.

  In the present embodiment, the gap forming step D-1 is started when such a state is reached. The work in the gap forming step D-1 is performed by adsorbing the uppermost metal plate 1 by a plurality of adsorbing members 37.

  When the uppermost metal plate 1 is adsorbed by the adsorbing member 37, the distance in the vertical direction of the pad member 39 is shortened as the pressure in the pad member 39 decreases. That is, the uppermost metal plate 1 moves (floats) upward as the pad member 39 is shortened.

  As shown in FIG. 4B, when the uppermost metal plate 1 is moved upward by the adsorption of the uppermost metal plate 1 by the adsorbing member 37, the upper surface of the uppermost metal plate 1 and 2 The distance L from the tip of the bar member 34 that contacts the th metal plate 1 will gradually increase.

As the distance L increases, the uppermost metal plate 1 is pressed against the contact portion between the bar member 34 and the second metal plate 1 from above (the second metal plate 1 from above is pressed by the bar member 34). From the top, the second metal plate 1 is gradually peeled off, and finally the second metal plate 1 from the top is separated (peeled off).
At this time, the insertion member 32 on the feed direction side (abutting on the upper surface of the uppermost metal plate 1) is further shortened in the vertical direction as the uppermost metal plate 1 is moved upward. It will be.

Next, the metal plate extraction step D-2, which is the next step of the gap formation step D-1, will be described with reference to FIG.
In the present embodiment, after the uppermost metal plate 1 is sucked by the adsorbing member 37, the metal plate extraction step D-2 is started when a predetermined condition is satisfied. As this predetermined condition, a predetermined time (for example, a time during which the uppermost metal plate 1 and the second metal plate 1 from the top can be separated from each other) elapses after the uppermost metal plate 1 is sucked by the adsorption member 37. And so on.

  As shown in FIG. 4C, in the metal plate extraction step D-2, the moving member 31 is moved upward while maintaining the suction state of the uppermost metal plate 1 by the plurality of adsorbing members 37. The work to convey to the metal plate forming apparatus used in the next metal plate forming step E is performed. As a result, the work (removal) for one metal plate 1 in the metal plate separation step D is completed.

  After that, a new uppermost metal plate (hereinafter referred to as “new uppermost metal plate”) 1 is taken out, that is, the new uppermost metal plate 1 is conveyed to the metal plate forming apparatus. The gap forming step D-1 and the metal plate removing step D-2 are performed again (see FIGS. 4A to 4C). Note that the new uppermost metal plate (second metal plate from the top in the example of FIG. 4) 1 is different from the metal plate (uppermost metal plate in the example of FIG. 4) 1 that has already been taken out. The position where the hole 1a is formed is the feed direction side. For this reason, in the gap forming step D-2 for taking out the new uppermost metal plate 1, the bar member 34 on the counter feed direction side contacts the upper surface of the new uppermost metal plate 1, while the bar on the feed direction side. The member 34 comes into contact with the metal plate 1 (the third metal plate from the top in the example of FIG. 4) adjacent to the new uppermost metal plate 1.

Next, the metal plate forming step E, which is the next step of the metal plate separating step D, will be described.
In the metal plate forming step E, the metal plate 1 conveyed to the metal plate forming apparatus is punched, pressed, or the like to manufacture (generate) a metal product having a predetermined shape.

  As described above, according to the present embodiment, since the metal plate 1 is only formed with the through holes 1a penetrating in the plate thickness direction, when the metal plates 1 are stacked in the vertical direction, the upper and lower two sheets are stacked. The metal plates 1 can be brought into close contact with each other. For this reason, according to this embodiment, even when many metal plates 1 are stacked, they can be stacked in an orderly manner while suppressing the stacking height.

  In the present embodiment, the metal plate removal step D-2 for taking out the uppermost metal plate 1 is performed after a gap is formed between the uppermost metal plate 1 and the second metal plate 1 from the top. (After performing the gap forming step D-1). For this reason, according to the present embodiment, the metal plates 1 can be taken out one by one, even though the metal plates 1 are easily adhered to each other in a stacked state by application of rust prevention oil or the like.

  Moreover, in the present embodiment, the insertion member 32 is (almost) moved in a state where the insertion member 32 inserted into the through hole 1a of the uppermost metal plate 1 is in contact with the second metal plate 1 from the top. Without doing so, only the uppermost metal plate 1 is moved upward. That is, in this embodiment, when the uppermost metal plate 1 is moved upward, the second metal plate 1 from the top is pressed downward by the insertion member 32. It is possible to force separation. Therefore, according to the present embodiment, when the uppermost metal plate 1 is taken out, it is possible to reliably suppress the disadvantage that the second metal plate 1 from the top is taken out at the same time.

For this reason, according to this embodiment, the uppermost metal plate 1 and the second metal plate 1 from the top can be more reliably separated.

  Next, the insertion member 332 will be described with reference to FIG. The insertion member 332 in the present embodiment is different from the above-described insertion member 32 (see FIG. 4) in that the fluid F can be blown out. The same components as those in the embodiment are denoted by the same reference numerals, and redundant description is omitted. Although not shown, in the present embodiment, a plurality of insertion members 332 are provided corresponding to the positions of the through holes 1a formed in the metal plate 1 as in the first embodiment. .

  As shown in FIG. 7, the insertion member 332 is similar to the moving member 31 (see FIG. 4), and has a substantially cylindrical tubular member (hereinafter referred to as “pipe member”) 333 fixed to the moving member 31. The pipe member 333 has a substantially rod-shaped rod member 334 provided therein.

This can be realized by configuring each through-hole 1a to move each time.

  The through-hole 1a formed in the metal plate 1 can be formed at a desired position, but such a through-hole 1a is originally present in the final metal product that has been formed. It must not be. For this reason, it is preferable to form the through-hole 1a in the part (for example, the window part of the door of a motor vehicle body) discarded when the metal plate 1 is pressed or stamped.

  Further, considering that the upper and lower metal plates 1 and 1 are smoothly separated by pressing the second metal plate 1 from the top by the insertion members 32, 132, 232 and 332, the through hole 1 a is The metal plate 1 is preferably formed on the center side rather than the end side.
