Next, in the simplified configuration explanatory diagram of FIG. 2A, the takeaway conveyor (conveyance conveyor) 2 is indicated by a number of small circles. 4 shows a simplified hot recovery conveyor. In this take-away conveyor (conveyance conveyor) 2, a swing conveyor 60 swings upward and downward as indicated by arrows 61 and 62, and is switched between the hot recovery conveyor 4 and the cooling line 3 of FIG. The tread is attached. Z is a continuous weigher, and the tread weight is continuously measured while being sent on the takeaway conveyor 2 as indicated by arrow F from the extruder 1 to detect whether or not the extrusion is stable. it can. A cutter Y is disposed immediately upstream of the swing conveyor 60. And the apparatus which concerns on this invention is equipped with the bag-shaped part formation means T and the press means P. FIG.
The bag-shaped part forming means T is on the conveyor 2 for feeding the tread 10 (shown by (B-1) in FIG. 2) that is extruded from the extruder 1, and the hot recovery conveyor 4 (swing conveyor 60). At the downstream position immediately after, the tip 10a of the tread 10 is gripped and lifted, and the tip 10a of the tread 10 is moved from (B-2) to (B-3) in FIG. As shown, the bag-like portion 5 is formed by folding.

As shown, a folded portion (overlapping portion) 6 is formed at the tip 10 a of the tread 10. If the swing conveyor 60 is inclined upward as shown by the solid line in FIG. 2, the tread 10 extruded from the extruder 1 is sent to the hot recovery conveyor 4 as indicated by the arrow F ', and hot return recovery is performed (tread). Until the weight stabilizes). At this time, it is possible to detect whether or not the tread weight is stabilized by the continuous weigher Z. When the weight of the tread is stabilized, the tread is cut by the cutter Y, and the swing conveyor 60 is immediately swung in the direction of the arrow 62, and the tread is cooled in the cooling line 3 (see FIG. 1). As shown by arrow F, in order to make the tip 10a of the tread 10 have a waist (giving rigidity) at that time, as will be described below, the bag-shaped portion forming means T and the pressing means The folded portion 6 shown in FIG. 2B-4 is formed by P.

図3〜図8に於て、主として袋状部形成手段T及び押圧手段Pの実施の一形態を作動順に例示する。搬送コンベア(テイクアウェイコンベア)2は、多数の平行かつ水平に並設されたローラ12を有するローラコンベアから成る。このローラコンベアのローラ12は、(図示省略の)エンドレス状駆動チェーンにて連動連結され、各々矢印Mで示すように、(図例では)反時計方向に回転駆動されていて、その上に載置状の(安定押出状態となった)トレッド10は、矢印F方向へ送りが与えられる。
隣り合うローラ12, 12の間には小間隔13が形成されている。14は、例えば左右一対のチャンネル材等から成るフレーム材であり、横桁材15等にて井桁組み等されると共に、図示省略の柱部材にて、搬送コンベア2のローラ12を回転自在に保持する基枠(図示省略)に連結されて、フレーム材14は、搬送コンベア2の上方に所定間隔をもって保持されている。袋状部形成手段Tは、図3に示すように、隣り合うローラ12とローラ12の間(小間隔13の対応位置)にて、トレッド10が送られてくるのを待機する受け部材7を有し、この受け部材7は側面視一文字状の帯板から成り、待機状態では、図3のように水平状として、かつ、ローラ12, 12の上面と同一高さ、乃至、僅かに下方位置(沈み込んだ位置)として、送られてくるトレッド10の先端10a(最先端部10c)の到着を待つ。しかも、左右のフレーム材14, 14に横架された支軸8廻りの回転可能に外嵌された円筒体9から延伸状に連設された揺動アーム16の先端に帯板状の受け部材7が設けられる。
3 to 8, an embodiment of the bag-shaped portion forming means T and the pressing means P is mainly illustrated in the order of operation. The transport conveyor (takeaway conveyor) 2 is composed of a roller conveyor having a large number of parallel and horizontal rollers 12. The rollers 12 of this roller conveyor are interlocked and connected by an endless drive chain (not shown), and are each driven to rotate counterclockwise (in the example shown in the figure) and mounted thereon. The stationary tread 10 (which is in a stable extruded state) is fed in the direction of arrow F.
A small gap 13 is formed between the adjacent rollers 12 and 12. 14 is a frame material made up of, for example, a pair of left and right channel members, and the like. The frame material 14 is connected to a base frame (not shown) to be held above the transport conveyor 2 at a predetermined interval. As shown in FIG. 3, the bag-shaped portion forming means T includes a receiving member 7 that waits for the tread 10 to be sent between the adjacent rollers 12 and the rollers 12 (corresponding positions at the small intervals 13). The receiving member 7 is formed of a band plate having a letter-like shape in side view. In the standby state, the receiving member 7 is horizontal as shown in FIG. 3 and is at the same height as the upper surfaces of the rollers 12 and 12 or slightly below. As the (sunk position), the arrival of the tip 10a (the most advanced portion 10c) of the tread 10 sent is awaited. Moreover, a belt-like receiving member is provided at the tip of the swing arm 16 extending in a stretched manner from the cylindrical body 9 that is rotatably fitted around the support shaft 8 that is horizontally mounted on the left and right frame members 14, 14. 7 is provided.

具体例では、揺動アーム16は、側面視多角形に折曲った複数本のアーム本体16aと、側面視多角形に折曲り状の板材16bと、を備え、両者は溶接やリベット等にて一体構造とされ、受け部材7はこの板材16bの先端縁を折曲げて、一体に形成するのが望ましい。多角形に折曲り状の揺動アーム16の凹部16cは、図3〜図8の右方向───即ち送りの上流側───を向いて、待機している。   In a specific example, the swing arm 16 includes a plurality of arm bodies 16a bent in a polygonal shape in a side view and a plate material 16b bent in a polygonal shape in a side view, both of which are formed by welding, rivets, or the like. It is preferable that the receiving member 7 is formed integrally by bending the leading edge of the plate member 16b. The concave portion 16c of the swing arm 16 bent in a polygon is waiting in the right direction in FIGS. 3 to 8, that is, the upstream side of the feed.

図3から図4に示すように、ローラ12の矢印M方向への回転によって、その上に載って送られてきた(重量安定化後の)トレッド10の先端10aの下面側を、受け部材7にて受けた状態(図4参照)で、丸棒状等のチャック部材17が、上記先端10aの上面側に接触して掴持する。
揺動アーム16の板材16bから凹部16c内へ突設された取付片18に横架された枢支軸19の軸心廻りに揺動自在に枢支された揺動杆20の一端20aに、上記チャック部材17が固着され、また、この揺動杆20は、他端20bが板材16bの(図示省略の)窓部を通して下流側(又は上方)へ突出状として、上記チャック部材17を開閉作動させる(後述の)第2アクチュエータ22にピン23にて連結(枢結)される。
As shown in FIGS. 3 to 4, the lower surface side of the tip 10 a of the tread 10 (after weight stabilization) sent on the roller 12 by rotating in the direction of arrow M of the roller 12 is placed on the receiving member 7. In the state (see FIG. 4), the chuck member 17 having a round bar shape contacts the upper surface side of the tip 10a and grips it.
At one end 20a of a swinging rod 20 that is pivotably supported around the axis of a pivotal shaft 19 that is horizontally mounted on a mounting piece 18 projecting from a plate 16b of the swinging arm 16 into the recess 16c, The chuck member 17 is fixed, and the swing rod 20 is operated to open and close the chuck member 17 with the other end 20b protruding downstream (or upward) through a window (not shown) of the plate 16b. The second actuator 22 (described later) is connected (pivoted) by a pin 23.

21は第1アクチュエータであって、左右一対のフレーム材14,14の一方の外側に配設され、この第1アクチュエータの上端は、フレーム材14や(ローラ12を保持する)基枠等の固定枠24から突設された取付片25に、ピン26にて枢着されている。第1アクチュエータ21の下端は、フレーム材14の外側に於て、円筒体9から突設された突出アーム27にピン28にて枢着されている。この第1アクチュエータ21は例えばエアーシリンダが好適である。この第1アクチュエータ21の往復作動によって、円筒体9が回転駆動されるので、円筒体9に固着されている揺動アーム16が、支軸8の軸心L8 廻りに揺動する。従って、第1アクチュエータ21によって、受け部材7及びチャック部材17を上昇・下降させられる。即ち、トレッド10の先端10aを掴持状態の受け部材7とチャック部材17は、その掴持状態のままで図4から図5のように上昇することができる。 Reference numeral 21 denotes a first actuator, which is disposed outside one of the pair of left and right frame members 14 and 14, and the upper end of the first actuator is fixed to the frame member 14 or a base frame (holding the roller 12). A pin 26 is pivotally attached to a mounting piece 25 projecting from the frame 24. A lower end of the first actuator 21 is pivotally connected to a projecting arm 27 projecting from the cylindrical body 9 by a pin 28 on the outside of the frame member 14. The first actuator 21 is preferably an air cylinder, for example. Since the cylindrical body 9 is rotationally driven by the reciprocating operation of the first actuator 21, the swing arm 16 fixed to the cylindrical body 9 swings around the axis L 8 of the support shaft 8. Therefore, the receiving member 7 and the chuck member 17 can be raised and lowered by the first actuator 21. That is, the receiving member 7 and the chuck member 17 in the state of holding the tip 10a of the tread 10 can be lifted as shown in FIGS.

ところで、第2アクチュエータ22もエアーシリンダが好ましいが、円筒体9の長手方向の中間から突設された突出片29, 29の間に揺動可能に取付けられる。つまり、図例では、第2アクチュエータ22としてのエアーシリンダのシリンダチューブの外周方向に突設された一対の支軸30, 30を、一対の突出片29, 29にて枢支し、第2アクチュエータ22の(伸縮)往復作動によって、揺動杆20を枢支軸19の軸心廻りに揺動して、チャック部材17を受け部材7に対して接近・分離させて、トレッド10の先端10aのチャッキング(掴持)、及び、開放を交互に行う。   Incidentally, the second actuator 22 is also preferably an air cylinder, but is attached so as to be swingable between projecting pieces 29 and 29 projecting from the middle in the longitudinal direction of the cylindrical body 9. That is, in the illustrated example, a pair of support shafts 30 and 30 projecting in the outer peripheral direction of the cylinder tube of the air cylinder as the second actuator 22 are pivotally supported by the pair of projecting pieces 29 and 29, and the second actuator By the reciprocating operation of 22 (extension / contraction), the rocking rod 20 is swung around the axis of the pivot shaft 19, and the chuck member 17 is moved toward and away from the receiving member 7 so that the tip 10a of the tread 10 Chucking (gripping) and opening are performed alternately.

そして、上記第1アクチュエータ21及び第2アクチュエータ22を作動させるために、トレッド10の搬送コンベア2上の位置を検出して検出信号を送信する検出手段51, 52, 53が、設けられている。
検出手段51, 52, 53は、図例では透過型であって、レーザー光を発射する発光器51a,52a,53aと、ローラ12, 12間を通してその下方位置で受光する光電管等の受光器51b,52b,53bとから、構成されている。
さらに詳しく説明すると、第1検出手段51は、受け部材7が待機する位置よりも僅かに上流側のローラ12, 12間の小間隔13をレーザー光線等の検出光が透過する位置に、配設される。第2検出手段52は(後に詳述する)押圧手段Pの直前(上流側)のローラ12, 12間の小間隔13を検出光が透過する位置に、配設される。また、第3検出手段53は押圧手段Pの直後(下流側)のローラ12, 12間の小間隔13を検出光が透過するように、配設される。しかも、第1検出手段51は、例えばトレッド掴持用、第2・第3検出手段52, 53は、例えば、トレッド押圧用である。
And in order to operate the said 1st actuator 21 and the 2nd actuator 22, the detection means 51,52,53 which detects the position on the conveyance conveyor 2 of the tread 10 and transmits a detection signal is provided.
The detecting means 51, 52, 53 are transmissive in the illustrated example, and are a light emitter 51a, 52a, 53a that emits laser light, and a light receiver 51b such as a phototube that receives light between the rollers 12 and 12 at a lower position. , 52b, 53b.
More specifically, the first detection means 51 is disposed at a position where the detection light such as a laser beam is transmitted through the small gap 13 between the rollers 12 and 12 slightly upstream of the position where the receiving member 7 stands by. The The second detection means 52 is disposed at a position where the detection light passes through the small gap 13 between the rollers 12 and 12 immediately before (on the upstream side of) the pressing means P (described in detail later). The third detection means 53 is arranged so that the detection light passes through the small gap 13 between the rollers 12 and 12 immediately after the pressing means P (downstream side). Moreover, the first detection means 51 is for, for example, a tread grip, and the second and third detection means 52, 53 are for, for example, a tread pressing.

次に、押圧手段Pについて説明すると、この押圧手段Pは、空転自在な2本のフリーローラ35, 35を平行に左右方向に枢着した押圧ヘッド36と、この押圧ヘッド36を昇降作動させる第3アクチュエータ43と、前述の上流側の袋状部形成手段Tにて形成されたトレッド10の袋状部5(図6,及び、図2の(B−3)参照)の先端縁5aがローラコンベア(搬送コンベア2)にて所定位置まで送られてきたことを検出して第3アクチュエータ43を作動(下降押圧作動)させる信号を送信する袋状部先端縁検出手段とを、備えている。
具体的に、前述の第2・第3検出手段52, 53が袋状部先端縁検出手段に相当する。
Next, the pressing means P will be described. The pressing means P includes a pressing head 36 in which two free-rolling free rollers 35, 35 are pivotally mounted in parallel in the left-right direction, and a first operation for moving the pressing head 36 up and down. 3 and the tip edge 5a of the bag-like portion 5 of the tread 10 (see FIGS. 6 and 2B-3) formed by the upstream bag-like portion forming means T is a roller. And a bag-shaped portion leading edge detecting means for detecting a signal sent to a predetermined position by the conveyor (conveying conveyor 2) and transmitting a signal for operating the third actuator 43 (lowering pressing operation).
Specifically, the second and third detection means 52 and 53 described above correspond to the bag-shaped portion leading edge detection means.

第3アクチュエータ43はエアーシリンダが好ましい。押圧ヘッド36は、リニアガイド機構40にて上下方向に案内され、エアーシリンダ等から成る第3アクチュエータ43の伸縮作動によって、十分な剛性と姿勢安定性を確保しつつ、昇降し、かつ、図7に示す押圧状態下で押圧ヘッド36がトレッド10から受ける水平下流方向の外力に十分に耐える。リニアガイド機構40としては、横桁材15に固着されたブロック体と、このブロック体のリニアベアリング(又はブッシュ材)を有する複数個の上下方向のガイド孔に、上下摺動自在に挿通されたガイド杆とから、構成されている。このように押圧ヘッド36は、複数本のガイド杆の下端に連結され、かつ、第3アクチュエータ43としてのエアーシリンダのピストンロッド下端に連結される。
そして、図7で明らかなように、トレッド10をローラ12…にて受けつつ、押圧ヘッド36が上方から押圧することで、袋状部5(図6参照)を、図7のように押圧して、折り畳み部6を形成する。
The third actuator 43 is preferably an air cylinder. The pressing head 36 is guided in the vertical direction by the linear guide mechanism 40, and moves up and down while securing sufficient rigidity and posture stability by the expansion and contraction operation of the third actuator 43 formed of an air cylinder or the like. The pressure head 36 sufficiently withstands the external force in the horizontal downstream direction received from the tread 10 under the pressing state shown in FIG. The linear guide mechanism 40 was inserted into a plurality of vertical guide holes having a block body fixed to the cross beam member 15 and a linear bearing (or bush material) of the block body so as to be vertically slidable. It consists of a guide rod. Thus, the pressing head 36 is connected to the lower ends of the plurality of guide rods, and is connected to the lower end of the piston rod of the air cylinder as the third actuator 43.
Then, as apparent from FIG. 7, the pressing head 36 presses from above while receiving the tread 10 with the rollers 12 to press the bag-like portion 5 (see FIG. 6) as shown in FIG. Thus, the folding part 6 is formed.

上述の第1・第2・第3アクチュエータ21, 22, 43がエアーシリンダである場合のその配管系統を、図4,図6,図7等に例示し、かつ、第1・第2・第3検出手段51, 52, 53からの出力信号によって第1・第2・第3アクチュエータ21, 22, 43が如何に制御されるかを簡略に、図4,図6,図7等に例示する。即ち、44はエアーポンプやコンプレッサ等の第1エアー源を示し、第1電磁弁45(実際は複数個の電磁弁)、及び、配管46a,46bを介して第1アクチュエータ21に接続され、また、配管47a,47bを介して第2アクチュエータ22に接続される。48は第2エアー源を示し、第2電磁弁49及び配管50a,50bを介して第3アクチュエータ43に接続される。

The piping system in the case where the first, second, and third actuators 21, 22, and 43 described above are air cylinders is illustrated in FIGS. 4, 6, and 7, and the first, second, and second actuators. How the first, second, and third actuators 21, 22, and 43 are controlled by the output signals from the three detecting means 51, 52, and 53 is illustrated in FIGS. . That is, 44 denotes a first air source such as an air pump or a compressor, which is connected to the first actuator 21 via the first solenoid valve 45 (actually a plurality of solenoid valves) and the pipes 46a and 46b. It is connected to the second actuator 22 via pipes 47a and 47b. Reference numeral 48 denotes a second air source, which is connected to the third actuator 43 via the second electromagnetic valve 49 and the pipes 50a and 50b.
54 is an electronic control means such as a personal computer, which is connected so that signals from the first, second and third detection means 51, 52 and 53 (the light receivers 51b, 52b and 53b) are inputted, and 1. The first and second electromagnetic valves 45 and 49 are connected to the first and second electromagnetic valves 45 and 49 through connection lines 55 and 56 so as to transmit a switching command signal. Note that one connection line 55, 56 is shown for simplicity.

次に、主として作動について説明すると共に、本発明についての補充説明をする。図1〜図9に於て、袋状部形成手段T,押圧手段Pは、ホット回収コンベア4の直後の搬送コンベア2上に設置される。トレッド10が流れていない時、即ち、第1検出手段51がトレッド10の最先端部10cを検出するまでは、袋状部形成手段Tは図3の待機状態にある。
つまり、第1アクチュエータ21が伸長して、揺動アーム16が下方へ揺動して、受け部材7は、ローラ12,12間の小間隔13に於て、ローラ12の上面と同一乃至それ以下の位置に存在して、その後、送られてくるトレッド10を確実に受ける態勢にある。このように、トレッド10の先端10aの詰まりを確実防止できる。このとき、第2アクチュエータ22は伸長しており、チャック部材17は上方へ開放した状態にある。なお、カッタYはスイングコンベア60の上流の近傍位置に設けられ、押出機1から押し出されてくるトレッド10の重量が安定しない間は、スイングコンベア10は上方位置(図2の実線位置)にあって、ホット回収コンベア4に送られてホット回収されるが、(連続秤量器Zによって)トレッド10の押し出されてくる重量が安定すると、カッタYによって切断され、スイングコンベア60が矢印62方向へ、揺動して、袋状部形成手段Tの存在する側へ送られる(図3の矢印F参照)。
Next, the operation will be mainly described, and a supplementary explanation of the present invention will be given. 1 to 9, the bag-shaped part forming means T and the pressing means P are installed on the transport conveyor 2 immediately after the hot recovery conveyor 4. When the tread 10 is not flowing, that is, until the first detecting means 51 detects the most distal end portion 10c of the tread 10, the bag-shaped portion forming means T is in the standby state of FIG.
That is, the first actuator 21 extends, the swing arm 16 swings downward, and the receiving member 7 is equal to or less than the upper surface of the roller 12 at a small distance 13 between the rollers 12 and 12. And is ready to receive the tread 10 sent afterwards. Thus, clogging of the tip 10a of the tread 10 can be reliably prevented. At this time, the second actuator 22 is extended, and the chuck member 17 is open upward. The cutter Y is provided near the upstream of the swing conveyor 60, and the swing conveyor 10 is in the upper position (solid line position in FIG. 2) while the weight of the tread 10 extruded from the extruder 1 is not stable. Then, it is sent to the hot recovery conveyor 4 to be hot recovered, but when the weight of the tread 10 is stabilized (by the continuous weighing device Z), it is cut by the cutter Y, and the swing conveyor 60 is moved in the direction of the arrow 62, It swings and is sent to the side where the bag-shaped part forming means T exists (see arrow F in FIG. 3).

このように、図3の矢印F方向に、搬送コンベア2によってトレッド10が流れて(送られて)くると、発光器51aの検出光線が遮断されたことを受光器51bにて検出すると、検出信号I1 が電子制御手段54に送られ、この電子制御手段54から第1電磁弁45に制御信号I2 を送信すると、第1電磁弁45が切換わって、図3から図4に示すように、第2アクチュエータ22が短縮作動し、揺動杆20が揺動して、チャック部材17が、受け部材7と共働して、先端10aを挾持(掴持)する。第1検出手段51の検出信号が送られてから、第2アクチュエータ22が伸長してチャック部材17の挾持(掴持)が完了するまでの微小時間は、制御手段54による調整自在なタイマー機能によって行われる。この調整自在なタイマー機能により、図4のように正確な位置にて、トレッド10の先端10aをチャッキング(掴持)できる。チャック部材17は丸棒としたので、トレッド接触面積が小さく、チャック状態(掴持状態)の密着保持力を十分に確保している。 In this way, when the tread 10 flows (sent) by the conveyor 2 in the direction of arrow F in FIG. 3, the detection of the light beam detected by the light emitter 51 a is detected by the light receiver 51 b. When the signal I 1 is sent to the electronic control means 54 and the control signal I 2 is transmitted from the electronic control means 54 to the first electromagnetic valve 45, the first electromagnetic valve 45 is switched, as shown in FIGS. In addition, the second actuator 22 is shortened, the swing rod 20 swings, and the chuck member 17 cooperates with the receiving member 7 to grip (hold) the tip 10a. The minute time from when the detection signal of the first detection means 51 is sent to when the second actuator 22 is extended and the chuck member 17 is held (gripped) is adjusted by a timer function adjustable by the control means 54. Done. With this adjustable timer function, the tip 10a of the tread 10 can be chucked (gripped) at an accurate position as shown in FIG. Since the chuck member 17 is a round bar, the tread contact area is small, and a sufficiently close contact holding force in the chucked state (gripping state) is ensured.

図4に示すチャック状態(掴持状態)となった直後(極微小時間後)、図4から図5に示すように第1アクチュエータ21を短縮し、円筒体9を回転させて、揺動アーム16を上方へ揺動する。このとき、第2アクチュエータ22は伸縮作動せず、チャック部材17はチャック状態(掴持状態)のままを維持している。上述の第1アクチュエータ21の短縮作動指令は、制御手段54内のタイマー機能、及び/又は、シーケンシャル機能によって、前記制御信号I2 の極微小時間後に送信される制御信号I3 によって行われる。要するに、図4に示したチャック(掴持)とほぼ同時に、又は、チャック確認直後に、このチャック(掴持)状態のままで、揺動アーム16が図4から図5のように揺動して、トレッド10の先端10aを持ち上げ、その状態を保つ。 Immediately after the chuck state (gripping state) shown in FIG. 4 is reached (after a very short time), the first actuator 21 is shortened as shown in FIGS. Swing 16 upward. At this time, the second actuator 22 does not expand and contract, and the chuck member 17 remains in the chucked state (gripped state). The shortening operation command of the first actuator 21 described above is issued by a control signal I 3 transmitted after a very short time of the control signal I 2 by a timer function and / or a sequential function in the control means 54. In short, the swing arm 16 swings as shown in FIGS. 4 to 5 in the chuck (gripping) state almost simultaneously with the chuck (gripping) shown in FIG. 4 or immediately after checking the chuck. Then, the tip 10a of the tread 10 is lifted and kept in that state.

搬送コンベア2によって引続いてトレッド10は矢印F方向へ送られてくるので、図6から図7、あるいは、図2の (B−2)(B−3) のように、袋状部5が形成されてくる。
押圧手段Pの第3アクチュエータ43は短縮状態を保ち、押圧ヘッド36は、図3〜図6の間、引続いて上昇位置を維持している。そして、第2検出手段52が矢印F方向に送られてくる袋状部5の先端縁5aを検出すると、検出信号I4 が制御手段54に送られ、制御手段54から第2電磁弁49に制御信号I5 を送信する。この制御信号I5 によって第2電磁弁49が切換わって、図6から図7のように、第3アクチュエータ43が伸長作動し、押圧ヘッド36が下降して、そのフリーローラ35, 35が、下方位置のローラ12Aと共働して、先端10a(袋状部5)を押圧・挾圧して、折り畳み部6を形成する。ところで、押圧ヘッド36の下降と略同時に、第2アクチュエータ22を伸長させて、トレッド10の先端10aのチャッキング(掴持)を開放する。即ち、制御手段54から、第2電磁弁49に前記信号I5 を送ると共に、極微小の時間差をもって、又は、同時に、制御信号I6 を第1電磁弁45へ送信し、第2アクチュエータ22を、図6から図7のように伸長させて、揺動杆20を揺動してチャック部材17を開放し、図7から図8のように、折り畳み部6がスムースに形成される。
Since the tread 10 is continuously sent in the direction of arrow F by the conveyor 2, the bag-like portion 5 is formed as shown in FIGS. 6 to 7 or (B-2) and (B-3) in FIG. Will be formed.
The third actuator 43 of the pressing means P is kept in a shortened state, and the pressing head 36 is continuously maintained in the raised position between FIGS. When the second detection means 52 detects the leading edge 5a of the bag-like portion 5 sent in the direction of arrow F, a detection signal I 4 is sent to the control means 54, and from the control means 54 to the second electromagnetic valve 49. A control signal I 5 is transmitted. The second electromagnetic valve 49 is switched by this control signal I 5 , the third actuator 43 is extended as shown in FIGS. 6 to 7, the pressing head 36 is lowered, and the free rollers 35, 35 are In cooperation with the roller 12A at the lower position, the front end 10a (bag-like portion 5) is pressed and pressed to form the folded portion 6. By the way, substantially simultaneously with the lowering of the pressing head 36, the second actuator 22 is extended to release chucking (gripping) of the tip 10a of the tread 10. That is, the control means 54 sends the signal I 5 to the second electromagnetic valve 49 and sends the control signal I 6 to the first electromagnetic valve 45 with a very small time difference or at the same time. 6 to 7, the rocking rod 20 is swung to release the chuck member 17, and the folding portion 6 is smoothly formed as shown in FIGS.

ところで、図7から少し矢印F方向へ折り畳み部6が送られて、最先端部10cまでが完全に重なり合ったタイミングを、制御手段54の(調整自在な)タイマー機能にて調整して、制御信号I7 を第2電磁弁49に送信することにより、第3アクチュエータ43を短縮させて、押圧ヘッド36を上昇させ、トレッドを送り出す。
なお、第3検出手段53の位置で、図6に示すように、先端縁5aを検出して、その検出信号I8 によって、制御手段54から制御信号I6 を送出させれば、押圧ヘッド36の下降タイミングが、前述の場合よりも、少し遅くなり、その結果、図9(B)に示すように、所定幅L6 の重なり部と、その先端の小袋部57とから成る形状の折り畳み部6が形成される。
By the way, the folding unit 6 is slightly sent in the direction of arrow F from FIG. 7, and the timing at which the leading end 10c completely overlaps is adjusted by the (adjustable) timer function of the control means 54, and the control signal By transmitting I 7 to the second electromagnetic valve 49, the third actuator 43 is shortened, the pressing head 36 is raised, and the tread is sent out.
If the tip edge 5a is detected at the position of the third detection means 53 as shown in FIG. 6 and the control signal I 6 is sent from the control means 54 by the detection signal I 8 , the pressing head 36 is used. falling timing of, than in the previous case, a bit slower, so that as shown in FIG. 9 (B), folded in the shape consisting of the overlapping portion having a predetermined width L 6, the distal end of the pouch portion 57 6 is formed.

なお、図9(A)は、図8に示した(前述の場合の)折り畳み部6である。このように、第3検出手段53によって、小袋部57を先端に有する折り畳み部6を形成して、点線の矢印58にて示す如く、ローラ12, 12間の小間隔13に、粘着力のあるトレッド10が侵入して詰まりや巻き込みを発生することを、一層確実に防止できる。
また、制御手段54のタイマー調整によって、第2電磁弁49及び第3アクチュエータ43の作動タイミングを調整することで、図9(A)と(B)のいずれかの形状を選択するようにしても良く、かつ、小袋部57の寸法も変更可能である。
FIG. 9A shows the folding unit 6 (in the case described above) shown in FIG. In this way, the folded portion 6 having the small bag portion 57 at the tip is formed by the third detecting means 53, and the small interval 13 between the rollers 12 and 12 has adhesive force as shown by the dotted arrow 58. It is possible to more reliably prevent the tread 10 from entering and causing clogging or entrainment.
Further, by adjusting the operation timing of the second electromagnetic valve 49 and the third actuator 43 by adjusting the timer of the control means 54, either one of the shapes shown in FIGS. 9A and 9B may be selected. The dimensions of the pouch portion 57 can be changed.

押出機1からトレッド押出を開始した直後は、トレッド重量が不安定であるため、押出開始から所定時間にわたってホットリターン回収を行うが、本発明では、袋状部形成手段T,押圧手段P等を具備し、図2中の連続秤量器Zによって重量が安定したことを検知すると、カッタYによってトレッドを切断して、スイングコンア60の(実線から破線への)切換えによって、袋状部形成手段T及び押圧手段Pへと送られて、図2の (B−1)(B−2)(B−3)(B−4) と順にトレッド10が加工されて、図1の冷却ライン3へ送り込まれる。従って、押出機1から安定してトレッド押出が行われるや否や、直ちに、ホット回収を中止して、図1に示した冷却ライン3へ切換えて、流すことが可能となり、不必要に長い間、ホット回収を行うことによるゴム品質の低下を防止し、最終製品の品質を安定化できる。さらに、生産時間のロスも減少でき、生産効率も改善できる。また、図1に示した冷却ライン3へ切換えて、連続して押出機1から押し出されるトレッド10を流した際、当然に、先端10aには折り畳み部6が(自動的に)形成されているので、ローラコンベア等を有する冷却ライン37, 38, 39等にて、(詰まりや巻き込み等が発生しないで)スムースに搬送されてゆくこととなる。 Immediately after starting the tread extrusion from the extruder 1, since the tread weight is unstable, hot return recovery is performed for a predetermined time from the start of extrusion. In the present invention, the bag-shaped portion forming means T, the pressing means P, etc. comprising, when it is detected that the weight stable by continuously weighing device Z in Fig. 2, by cutting the tread by the cutter Y, swing Con bare 60 (from the solid line to the dashed line) by the switching, the bag-like portion formed The tread 10 is processed in the order of (B-1), (B-2), (B-3), and (B-4) in FIG. 2 to the cooling means 3 in FIG. It is sent to. Therefore, as soon as the tread extrusion is stably performed from the extruder 1, it is possible to immediately stop the hot recovery and switch to the cooling line 3 shown in FIG. It is possible to prevent deterioration of rubber quality due to hot recovery and to stabilize the quality of the final product. In addition, production time loss can be reduced and production efficiency can be improved. Moreover, when the tread 10 continuously pushed out from the extruder 1 is flowed by switching to the cooling line 3 shown in FIG. 1, the folded portion 6 is naturally (automatically) formed at the tip 10a. since, so that in a cooling line 37, 38, 39 or the like having a low Rako conveyer or the like, Yuku is conveyed smoothly (in clogging or inclusion or the like does not occur).

また、本発明によれば、(手作業によらずに)自動的にトレッド10の先端10aに折り畳み部6が形成できるので、作業者は搬送(テイクアウェイ)コンベア2の近くにて待機している必要もなくなり、搬送(テイクアウェイ)コンベア2上で、センターライン管理、カラーライン管理、サイズマーク管理等の他の作業を、作業者は適確にスムースに行う時間的余裕も生まれ、良品トレッドを無駄なく冷却ライン3へ流すことができる。さらに、先端折り畳み作業時に作業者の身体が巻き込まれる等の危険も防止できるので、作業安全面についても貢献できる発明である。なお、冷却ライン3上を連続的にトレッド10が流れている通常状態では、自動切断手段Yのカッター部、袋状部形成手段Tの受け部材7(揺動アーム)、押圧手段Pの押圧ヘッド36は、上昇位置(上部)にあって、待機している。   In addition, according to the present invention, the folding portion 6 can be automatically formed at the tip 10a of the tread 10 (instead of by manual work), so that the worker waits near the conveyor (takeaway) conveyor 2. There is no need to be on the conveyor (take-away) conveyor 2, and the operator has time to perform other tasks such as center line management, color line management, and size mark management accurately and smoothly. Can flow to the cooling line 3 without waste. Furthermore, since it is possible to prevent danger such as the operator's body being caught during the tip folding work, the invention can also contribute to work safety. In a normal state where the tread 10 is continuously flowing on the cooling line 3, the cutter part of the automatic cutting means Y, the receiving member 7 (swinging arm) of the bag-like part forming means T, and the pressing head of the pressing means P. 36 is in the raised position (top) and is waiting.

なお、本発明は上述の実施の形態に限定されず設計変更自由であって、検出手段51, 52, 53としては、反射型のものを用いたり、他の近接スイッチや、近接センサーを用いることもできる。また、押圧ヘッド36のフリーローラ35, 35の代りに、エンドレスベルトを用いることも自由である。また、アクチュエータ21, 22, 43として、油圧シリンダとしたり、又は、電気駆動のものとすることも、自由である。   It should be noted that the present invention is not limited to the above-described embodiment, and the design can be freely changed. As the detection means 51, 52, 53, a reflective type, other proximity switches, or proximity sensors can be used. You can also. Further, an endless belt can be used in place of the free rollers 35 and 35 of the pressing head 36. The actuators 21, 22 and 43 can be hydraulic cylinders or can be electrically driven.
