すなわち、ストッパ手段１６を介して互いに接触している２つの加熱材１４がコンベア１２上で停止された状態で、第２および第３シリンダ４４、６２が同期駆動され、第２係止棒体４８がコンベア１２側に突出する一方、連結部材６６を介して揺動ガイド５４ａ、５４ｂが前記コンベア１２から離間する方向に一体的に揺動する。従って、図４に示すように、第２係止棒体４８は、加熱材１４同士の接触部位１８をガイド手段２２側に突き当てる一方、揺動ガイド５４ａ、５４ｂが前記接触部位１８から離間する方向に揺動し、該接触部位１８が分離される。
【００２３】
そこで、ストッパ手段１６を構成する第１シリンダ３６が駆動されて第１係止棒体４０がコンベア１２上から退避する一方、第２および第３シリンダ４４、６２が待機状態に同期駆動される。すなわち、図５に示すように、第２シリンダ４４を介して第２係止棒体４８が固定ガイド２４ａの第２開口部５０内に退避するとともに、第３シリンダ６２を介して連結部材６６が前方に突出し、揺動ガイド５４ａ、５４ｂが前記コンベア１２側に揺動して固定ガイド２４ｂと同一面上に配置される。これにより、加熱材１４同士が互いに分離され、前記加熱材１４は、互いに間隔を設けてコンベア１２を介し次段の工程、例えば、熱間プレス工程へと自動的に搬送される。
【００２４】
この場合、本実施形態では、コンベア１２上を搬送されてくる加熱材１４同士が互いに接触している際には、前記加熱材１４の先端部をストッパ手段１６で保持した状態で、突き出し手段２０を介して該加熱材１４の接触部位１８を搬送方向に交差する方向に突き当てる一方、この突き出し手段２０と対向して配置されているガイド手段２２を介して揺動ガイド５４ａ、５４ｂが前記接触部位１８から離間する方向に揺動する。
【００２５】
このため、図４に示すように、互いに接触していた加熱材１４は、その接触部位１８から容易かつ確実に分離され、前記加熱材１４の分離不良の発生を確実に阻止することができる。従って、図示しない熱間プレス機に対し加熱材１４を１つずつ確実に送り込むことが可能となり、例えば、２つの加熱材１４が一体的に前記加熱プレス機に搬入されてしまい、プレス工程が停止されるという不具合を可及的に回避し、効率的な熱間プレス工程が遂行されるという効果が得られる。
【００２６】
しかも、本実施形態では、コンベア１２上に搬送されてくる加熱材１４が他の加熱材１４と接触していない場合には、分離搬送装置１０が駆動されない。このため、特に、コンベア１２の摩耗を大幅に低減し得るという利点がある。
【００２７】
さらにまた、加熱材１４の長さを変更する際には、ストッパ手段１６を構成する可動ベース３０を長孔３２ａ、３２ｂに沿って矢印Ａ方向に位置調整するだけで容易に対応させることが可能になる。また、突き出し手段２０による突き出しトルクは、第２シリンダ４４のエア圧力を、例えば、レギュレータを介して調整することにより容易に変更することができ、加熱材１４の分離作業が一層高精度に遂行される。
【００２８】
【発明の効果】
本発明に係る加熱材の分離搬送方法および装置では、互いに接触状態の加熱材の先端部がストッパ手段により保持された状態で、前記加熱材同士の接触部位に突き出し手段が突き当てられる一方、前記突き出し手段に対向配置されているガイド手段が前記接触部位から離間する方向に揺動する。このため、加熱材同士がその接触部位から容易かつ確実に分離され、前記加熱材の分離不良を可及的に低減することが可能になる。しかも、加熱材同士が接触した場合にのみ、分離動作が行われるため、加熱材の分離搬送作業全体が効率的に遂行されるとともに、例えば、コンベアの摩耗が有効に低減される。

[Problems to be solved by the invention]
However, in the above-described prior art, since the grooved roller 6 is brought into contact with all the heating materials 8 conveyed by the conveyor chain 4, wear of the conveyor chain 4 is remarkably increased and the grooved roller 6 is connected to the sprocket 2a or 2b. The load on the driving unit is also considerably large.
[0005]
Moreover, in the structure using the rotational impact of the grooved roller 6, it is pointed out that the heating materials 8 that are in contact with each other cannot be reliably separated, and the efficiency of the entire hot press molding cannot be achieved. ing. Further, the operator always observes the separated state of the heating material 8, and when a separation failure occurs, it is necessary to perform an operation of separating the heating materials 8 with a hammer or the like.

For this reason, the contact portion between the heating materials protrudes in a direction intersecting the conveying direction of the conveyor, the contact portions are separated from each other, and then the stopper means and the protrusion means are retracted while the guide means advances. The heating materials separated from each other are conveyed along the conveyor.
[0008]
Thus, since the contact part of heating materials is reliably isolate | separated under the effect | action of a protrusion means and a guide means, each heating material can be smoothly and reliably conveyed at intervals. In addition, the protruding means and the guide means can be used only when the heating materials are conveyed in contact with each other. Therefore, the amount of wear of the conveyor is greatly reduced, and the load on the driving unit of the conveyor can be effectively reduced.
[0009]
Further, according to the present invention, the stopper means and the protrusion means only need to be provided with a locking rod body that can be advanced and retracted on the conveyor under the action of the actuator, respectively, and these configurations are effectively simplified. Moreover, the position of the stopper means can be adjusted in the conveying direction of the conveyor, can easily cope with a change in the dimensions of the heating material, and is excellent in versatility.
[0010]
Further, the heating material separating and conveying apparatus according to the present invention is a heating material separating and conveying apparatus for conveying the heating materials conveyed on the conveyor at intervals, and in a state of being in contact with each other. The stopper means for holding the conveyance direction tip of the heating material to be conveyed, the protruding means abutted against the contact portion between the heating materials in a state where the conveyance direction tip is held, and the heating material And a guide means which is disposed opposite to the protruding means and is swung in a direction away from the contact portion, and the guide means is slidably engaged with a fixed guide disposed along the conveyor.

The stopper means 16 includes a movable base 30, and the movable base 30 is inserted into the mounting base 28 through a plurality of set screws 34 inserted into elongated holes 32 a and 32 b formed elongated in the direction of arrow A. It is fixed in the A direction so that the position can be adjusted. A first cylinder (actuator) 36 is fixed on the movable base 30, and a first rod 38 projects from the first cylinder 36 in an arrow B direction intersecting the arrow A direction. The body 40 is connected. The first locking rod body 40 is inserted into the first opening 42 formed in the fixed guide 24a. The first opening 42 is formed in a long shape in the arrow A direction corresponding to the adjustment range of the first locking rod body 40 in the arrow A direction.
[0015]
The protruding means 20 includes a second cylinder (actuator) 44 fixed on the mounting base 28, and a second locking rod body 48 is provided on the second rod 46 extending from the second cylinder 44 in the direction of arrow B. Connected. The second locking rod 48 is inserted into a circular second opening 50 formed in the fixed guide 24a.
[0016]
The guide means 22 includes a pair of swing guides 54a and 54b that are slidably engaged with the fixed guide 24b via hinges 52a and 52b, and the distal ends of the swing guides 54a and 54b have a long hole 56 and a pin. 58 is engaged. A third cylinder (actuator) 62 is attached to the fixed guide 24b via a mounting base 60. A third rod 64 extending from the third cylinder 62 in the direction of arrow B is attached to the tip of the swing guide 54a. An engaging member 66 that engages is provided.
[0017]
As shown in FIG. 1, the separating and conveying apparatus 10 is provided with detection means 68 for detecting the heating material 14 on the conveyor 12. This detection means 68 is composed of a photoelectric tube 70 and a proximity switch (not shown), and a function of sending a separation processing signal to the separation conveying device 10 when it is detected that the heating materials 14 being conveyed are in contact with each other. have.
[0018]
The operation of the separating and conveying apparatus 10 configured as described above will be described below in relation to the separating and conveying method according to the embodiment of the present invention.
[0019]
First, when the heating material 14 heated to a predetermined temperature in advance by a heating furnace (not shown) is sequentially conveyed through the conveyor 12 (see FIG. 2), the heating materials 14 come into contact with each other by the detecting means 68. It is detected whether or not. Here, if it is determined that the heating materials 14 are in contact with each other, the first cylinder 36 constituting the stopper means 16 is driven, and the first locking rod 40 is integrated with the first rod 38 to convey the conveyor 12. Protruding to the side. For this reason, as shown in FIG. 3, the first locking rod 40 protrudes into the conveyor 12 through the first opening 42 of the fixed guide 24a, and is conveyed in the direction of arrow A while being in contact with each other. The tip of the heating material 14 is held in contact with the first locking rod 40.
[0020]
Next, the second cylinder 44 constituting the protruding means 20 and the third cylinder 62 constituting the guide means 22 are driven and controlled in synchronization. The synchronous operation of the second and third cylinders 44 and 62 is shown in Table 1.
[0021]
[Table 1]

[0022]
That is, the second and third cylinders 44 and 62 are synchronously driven in a state where the two heating materials 14 that are in contact with each other via the stopper means 16 are stopped on the conveyor 12, and the second locking rod body 48. Protrudes toward the conveyor 12, and the swing guides 54 a and 54 b swing integrally in a direction away from the conveyor 12 through the connecting member 66. Therefore, as shown in FIG. 4, the second locking rod 48 abuts the contact portion 18 between the heating members 14 against the guide means 22 side, while the swing guides 54 a and 54 b are separated from the contact portion 18. Oscillate in the direction and the contact site 18 is separated.
[0023]
Therefore, the first cylinder 36 constituting the stopper means 16 is driven and the first locking rod 40 is retracted from the conveyor 12, while the second and third cylinders 44 and 62 are driven synchronously in the standby state. That is, as shown in FIG. 5, the second locking rod 48 is retracted into the second opening 50 of the fixed guide 24 a via the second cylinder 44, and the connecting member 66 is connected via the third cylinder 62. Projecting forward, the swing guides 54a and 54b swing to the conveyor 12 side and are arranged on the same plane as the fixed guide 24b. Thereby, the heating materials 14 are separated from each other, and the heating materials 14 are automatically conveyed to the next step, for example, a hot pressing step, via the conveyor 12 with a space therebetween.
[0024]
In this case, in this embodiment, when the heating materials 14 conveyed on the conveyor 12 are in contact with each other, the protruding means 20 with the tip end portion of the heating material 14 held by the stopper means 16. The contact portion 18 of the heating material 14 is abutted in a direction crossing the conveying direction via the guide member 22, while the swinging guides 54 a and 54 b are brought into contact with each other via the guide means 22 arranged opposite to the protrusion means 20. It swings in a direction away from the part 18.
[0025]
Therefore, as shown in FIG. 4, the heating materials 14 that have been in contact with each other can be easily and reliably separated from the contact portion 18, and the occurrence of poor separation of the heating material 14 can be reliably prevented. Therefore, it becomes possible to reliably feed the heating materials 14 one by one to a hot press machine (not shown). For example, two heating materials 14 are integrally carried into the heating press machine, and the pressing process is stopped. The effect that an efficient hot press process is performed can be obtained by avoiding the trouble of being performed as much as possible.
[0026]
Moreover, in the present embodiment, when the heating material 14 conveyed on the conveyor 12 is not in contact with the other heating material 14, the separation conveying device 10 is not driven. For this reason, there is an advantage that the wear of the conveyor 12 can be greatly reduced.
[0027]
Furthermore, when changing the length of the heating material 14, it is possible to easily cope with the movable base 30 constituting the stopper means 16 only by adjusting the position in the arrow A direction along the long holes 32a and 32b. become. Further, the projecting torque by the projecting means 20 can be easily changed by adjusting the air pressure of the second cylinder 44 through, for example, a regulator, so that the separation work of the heating material 14 is performed with higher accuracy.
