Is retracted to a position where the tip of the head 67 (, 67,...) Protruding into the hopper 62 is retracted into each slit, and locked in that position. It has come to be able to do.

前述したホッパ62の下方には、ホッパ62の排出口62cから排出された収納袋F及びその収納物を機体61から搬出する搬出コンベア70の一側部が前記排出口62cに臨ませて配設してあり、搬出コンベア70の他側部は、機体61の他側壁に開設した開口から外へ延出させてある。   Below the hopper 62 described above, one side portion of the storage bag F discharged from the discharge port 62c of the hopper 62 and a carry-out conveyor 70 for carrying the stored items out of the machine body 61 faces the discharge port 62c. And the other side part of the carry-out conveyor 70 is extended outside from the opening opened in the other side wall of the body 61. FIG.

このような破袋機では、駆動部によって回転軸64及び第1板状刃体65(,65,…)を回転駆動させておき、この第1板状刃体65(,65,…)によって、ホッパ62内に投入された収納袋Fをホッパ62の排出口62cへ送り、排出口62c近傍位置に突出させた第2板状刃66(,66,…)の頭部67(,67,…)先端部分及び第1板状刃体65(,65,…)によって収納袋Fを切破することによって、収納袋Fから収納物を放出させ、ホッパ62の排出口62cから排出された収納袋F及び収納物を搬出コンベア70によって機体 の外へ搬出する。   In such a bag breaker, the rotary shaft 64 and the first plate-like blade body 65 (, 65,...) Are driven to rotate by the drive unit, and the first plate-like blade body 65 (, 65,...) The storage bag F put into the hopper 62 is sent to the discharge port 62c of the hopper 62, and the head 67 (, 67,...) Of the second plate-like blade 66 (, 66,. ...) The storage bag F is broken by the front end portion and the first plate-like blade body 65 (, 65, ...), so that the stored items are discharged from the storage bag F and discharged from the discharge port 62c of the hopper 62. The bag F and the stored items are carried out of the machine body by the carry-out conveyor 70.

このとき、第1板状刃65(,65,…)と第2板状刃66(,66,…)の頭部67(,67,…)先端部分との間で、収納袋Fの詰まりが生じた場合、シリンダ68を作動させて第2板状刃66(,66,…)を、ホッパ62内に突出した頭部67(,67,…)先端部分が上部仕切り板62aの各スリット内へ退入する位置まで後退させて、その位置でロックさせることによって、詰まった収納袋Fの払い出しを行なうようになっていた。
特開平6−170265号公報(図1)
At this time, the storage bag F is clogged between the first plate-like blade 65 (, 65,...) And the head 67 (, 67,...) Tip portion of the second plate-like blade 66 (, 66,...). When the cylinder 68 is operated, the second plate-like blades 66 (, 66,...) And the heads 67 (, 67,...) Projecting into the hopper 62 are slits of the upper partition plate 62a.

JP-A-6-170265 (FIG. 1)

しかしながら、このような従来の破袋機にあっては、第1板状刃体65(,65,…)は2枚の雲形刃を軸対象に設けてなるため、切破された収納袋Fが第1板状刃65(,65,…)に絡み付く場合も多く発生し、そのような場合は、第1板状刃体65(,65,…)の回転駆動を停止して、作業員が第1板状刃65(,65,…)から収納袋Fを除去しなければならず、破袋作業を効率的に実施することができないという問題があった。   However, in such a conventional bag breaking machine, since the first plate-like blade body 65 (, 65,...) Is provided with two cloud-shaped blades as axial objects, the cut storage bag F Is often entangled with the first plate-like blade 65 (, 65,...). In such a case, the rotation drive of the first plate-like blade body 65 (, 65,. However, the storage bag F had to be removed from the first plate-like blade 65 (, 65,...), And there was a problem that the bag breaking operation could not be performed efficiently.

また、外寸が小さな収納袋Fでも確実に切破すべく、第1板状刃65(,65,…)と第2板状刃66(,66,…)との間隔を比較的狭く設定した場合、外寸が大きい収納物が第1板状刃65(,65,…)と第2板状刃66(,66,…)との間に詰まり、第1板状刃65(,65,…)、第2板状刃66(,66,…)及び第1板状刃65(,65,…)の駆動部に破損・故障が生じる虞があった。また、当該収納物がビンである場合は、当該収納物が破損して、後処理である分別作業に困難を来たしていた。一方、外寸が大きい収納物でも確実にホッパ62から排出させるべく、第1板状刃65(,65,…)と第2板状刃66(,66,…)との間隔を比較的広く設定した場合、外寸が小さな収納袋Fが切破されずにホッパ62から排出されてしまう場合が生じるという問題もあった。   Further, in order to surely break even the storage bag F having a small outer dimension, the interval between the first plate-like blade 65 (, 65,...) And the second plate-like blade 66 (, 66,...) Is set to be relatively small. In this case, the stored item having a large outer size is clogged between the first plate-like blade 65 (, 65,...) And the second plate-like blade 66 (, 66,...), And the first plate-like blade 65 (, 65). ,..., And the drive portions of the second plate-like blades 66 (, 66,...) And the first plate-like blades 65 (, 65,...) May be damaged. In addition, when the stored item is a bin, the stored item is damaged, and it is difficult to perform a post-treatment sorting operation. On the other hand, the interval between the first plate blades 65 (, 65,...) And the second plate blades 66 (, 66,. When set, there is a problem that the storage bag F having a small outer dimension may be discharged from the hopper 62 without being cut.

本発明は、斯かる事情に鑑みてなされたものであって、切破した収納袋を確実に排出して破袋作業を効率的に実施し得る一方、外寸が小さな収納袋であっても確実に切破することができると共に、外寸が大きい収納物を可及的に破損させることなく排出することができる破袋機を提供する。   The present invention has been made in view of such circumstances, and even when a storage bag having a small outer dimension can be efficiently discharged by securely discharging the cut storage bag. Provided is a bag breaker that can be surely cut and can discharge a stored item having a large outer dimension without damaging it as much as possible.

請求項2記載の本発明は、更に、相隣る各送り歯の間隙内にそれぞれ、切破された収納袋を脱離させる脱離部材が挿入してあることを特徴とする破袋機を提供する。   The present invention described in claim 2 further includes a bag breaking machine, wherein a detaching member for detaching the cut storage bag is inserted in the gap between the adjacent feed dogs. provide.

請求項3記載の本発明は、前記進退駆動部は、各破袋爪を適当な時間間隔で退進駆動するようにしてあることを特徴とする破袋機を提供する。   According to a third aspect of the present invention, there is provided a bag breaker characterized in that the advance / retreat drive unit drives the bag break pawls to retreat at an appropriate time interval.

請求項1記載の本発明では、破対機は、収納物を収納した収納袋を投入する投入口と、切破した収納袋及びその収納物を排出する排出口との間を連通させてなる機体と、この機体内の前記投入口と排出口との間の適宜位置に横架させた回転軸と、回転軸にその軸長方向へ距離を隔てて外嵌させてなり、収納袋を前記排出口へ送る複数の送り歯と、各送り歯で送られる収納袋を案内すべく、各送り歯から所定距離を隔てて各送り歯に対向する位置に、各送り歯から離隔する方向へ揺動可能に軸支してあり、各送り歯と位置を異ならせて複数のスリットが開設してある案内板と、離隔する方向へ揺動した案内板を元の姿勢に復帰させるべく付勢する付勢部材と、前記案内板と前記各送り歯との間隙内を前記排出口へ収納袋を送らせるように前記回転軸を回転駆動する回転駆動部と、収納袋を切破する先端部を前記案内板の各スリットからそれぞれ突出させてなる複数の破袋爪と、各破袋爪を対応するスリット内へ退入させ、元の位置へ前進させる進退駆動部とを備えている。   In the first aspect of the present invention, the breaker communicates between the input port for inserting the storage bag storing the stored items and the cut-out storage bag and the discharge port for discharging the stored items. A machine body, a rotary shaft horizontally installed at an appropriate position between the input port and the discharge port in the machine body, and externally fitted to the rotary shaft at a distance in the axial length direction. In order to guide the plurality of feed dogs to be sent to the discharge port and the storage bag to be fed by each feed dog, the guide is swung in a direction away from each feed dog at a predetermined distance from each feed dog and facing each feed dog. A guide plate that is pivotally supported and has a plurality of slits at different positions from each feed dog, and a guide plate that oscillates in a separate direction is biased to return to the original posture. The rotating bag is fed to the discharge port through the gap between the biasing member, the guide plate and each feed dog. Rotation drive unit that rotates the shaft, a plurality of bag breaking pawls, each having a leading end that cuts the storage bag projecting from each slit of the guide plate, and each bag breaking pawl retracts into the corresponding slit And an advancing / retreating drive unit that moves forward to the original position.

従って、ビン・カン等の収納物を収納した収納袋が投入口から機体内へ投入されると、その収納袋は回転軸に外嵌させた複数の送り歯によって、案内板と各送り歯との間隙を排出口へ送られる。この案内板と送り歯との間隙は、比較的外寸が小さい収納袋でも確実に切破し得る寸法にしておく。このとき、外寸が大きい収納物を収納した収納袋が投下された場合であっても、当該収納物が送り歯の送り力によって案内板に圧接した場合、案内板を付勢している付勢部材に抗して案内板と送り歯との間隙が拡大するので、収納袋は収納物に破損が生じることなく前記間隙を通過することができる。   Therefore, when a storage bag storing items such as bins and cans is inserted into the machine body from the input port, the storage bag is guided by the plurality of feed teeth externally fitted to the rotating shaft, and the guide plate and each feed dog. Is sent to the outlet. The gap between the guide plate and the feed dog is set to a dimension that can be surely broken even with a storage bag having a relatively small outer dimension. At this time, even when a storage bag storing a stored item having a large outer size is dropped, if the stored item is pressed against the guide plate by the feed force of the feed dog, the guide plate is biased. Since the gap between the guide plate and the feed dog increases against the biasing member, the storage bag can pass through the gap without causing damage to the stored items.

一方、かかる収納袋が通過すると、付勢部材の付勢によって案内板が元の姿勢に復帰するので、比較的外寸が小さい収納袋でも確実に切破することができる。   On the other hand, when the storage bag passes, the guide plate returns to the original posture by the urging of the urging member, so that even the storage bag having a relatively small outer dimension can be reliably broken.

案内板に開設した各スリットからそれぞれ破袋爪の先端部が突出させてあり、送り歯によって前記間隙内を送られた収納袋は、各破袋爪の先端部によって切破され、この収納袋及び収納袋から放出された収納物が排出口から機体外へ排出される。その際、収納物たるビン・ペットボトル等が送り歯で送られる場合、それらに貼着されたラベル等が破袋爪の先端部に引っ掛かるので、ラベル等の大部分が破袋爪の先端部によって削取される。   The leading end of the bag breaking claw protrudes from each slit established in the guide plate, and the storage bag sent through the gap by the feed dog is cut by the leading end of each bag breaking claw. And the storage thing discharge | released from the storage bag is discharged | emitted from the discharge port outside the body. At that time, when bottles, plastic bottles, etc., which are stored items are fed with feed teeth, the labels attached to them are caught on the tip of the bag breaking nail, so the majority of the label etc. is the tip of the bag breaking nail. Is scraped by.

また、送り歯では収納袋を切破しない一方、切破された収納袋が破袋爪の先端部に絡み付いた場合であっても、進退駆動部によって破袋爪がスリット内に退入されて、当該収納袋は案内板によって濾され、破袋爪から脱離されるので、切破された収納袋を除去すべく破袋動作を中断することなく、連続的に行なわせることができ、破袋作業を効率的に実施することができる。   In addition, the feed dog does not cut the storage bag, but even if the cut storage bag is entangled with the tip of the bag claw, the bag claw is retracted into the slit by the advance / retreat drive unit. Since the storage bag is filtered by the guide plate and detached from the bag breaking claw, the bag breaking operation can be continuously performed without interrupting the bag breaking operation to remove the cut bag. Work can be performed efficiently.

請求項2記載の本発明では、相隣る各送り歯の間隙内にそれぞれ、切破された収納袋を脱離させる脱離部材が挿入してあるため、切破された収納袋が、相隣る送り歯の間に嵌入した場合であっても、そのような収納袋は送り歯の回転に伴って脱離部材に当接し、脱離部材によって送り歯の間から脱離除去される。   In the present invention described in claim 2, since the detaching members for detaching the cut storage bags are inserted into the gaps between the adjacent feed dogs, the cut storage bags are connected to each other. Even when it is inserted between adjacent feed dogs, such a storage bag comes into contact with the detachable member as the feed dog rotates, and is detached and removed from between the feed teeth by the detachable member.

請求項3記載の本発明では、進退駆動部は、各破袋爪を適当な時間間隔で退進駆動するようにしてあるため、切破された収納袋が各破袋爪に過剰に絡み付く前に、破袋爪から収納袋を脱離させることができる。これによって、オペレータによって各破袋爪を退進駆動させる必要がないため、破袋作業をより効率的に実行することができる一方、破袋爪の先端部によるラベル等の削取能の低下が防止される。   In the present invention described in claim 3, since the advancing and retracting drive unit is configured to retract each bag breaking claw at an appropriate time interval, before the cut storage bag is excessively entangled with each bag breaking claw. In addition, the storage bag can be detached from the bag breaking claw. As a result, it is not necessary for the operator to drive each bag breaking claw backward, so that the bag breaking operation can be executed more efficiently, while the cutting ability of labels and the like due to the tip of the bag breaking claw is reduced. Is prevented.

本発明に係る破袋機は、収納物を収納した収納袋を投入する投入口と、切破した収納袋及びその収納物を排出する排出口との間を連通させてなる機体内の前記投入口と排出口との間の適宜位置に回転軸が横架させてあり、この回転軸に収納袋を前記排出口へ送る複数の送り歯が、回転軸の軸長方向へ距離を隔てて外嵌させてある。また、機体内には、各送り歯で送られる収納袋を案内する案内板が、各送り歯から所定距離を隔てて各送り歯に対向する位置に、各送り歯から離隔する方向へ揺動可能に軸支してあり、この案内板には、各送り歯と位置を異ならせて複数のスリットが開設してある。   The bag-breaking machine according to the present invention is the above-mentioned loading in the machine body in which the input port for inserting the storage bag storing the stored items and the cut-out storage bag and the discharge port for discharging the stored items are communicated. A rotating shaft is horizontally mounted at an appropriate position between the mouth and the discharge port, and a plurality of feed dogs that feed the storage bag to the discharge port are separated by a distance in the axial length direction of the rotating shaft. It is fitted. In addition, a guide plate that guides the storage bag that is fed by each feed dog in the body swings in a direction away from each feed dog at a predetermined distance from each feed dog and facing each feed dog. The guide plate is pivotally supported, and a plurality of slits are formed in the guide plate at different positions from the feed dogs.

また、案内板には、離隔する方向へ揺動した案内板を元の姿勢に復帰させるべく付勢する付勢部材が連結してある。前述した回転軸を回転駆動する回転駆動部は、案内板と各送り歯との間隙内を前記排出口へ収納袋を送らせるようにしてあり、複数の破袋爪が、収納袋を切破する先端部を前記案内板の各スリットからそれぞれ突出させてある。そして、進退駆動部は、各破袋爪を対応するスリット内へ退入させ、再び元の位置へ前進させるようにしてある。   The guide plate is connected to a biasing member that biases the guide plate that swings in the separating direction to return to the original posture. The rotational drive unit that rotationally drives the rotary shaft described above is configured to allow the storage bag to be fed to the discharge port through the gap between the guide plate and each feed dog, and a plurality of bag breaking claws cut through the storage bag. The leading end is projected from each slit of the guide plate. The advancing / retreating drive unit retreats each bag breaking claw into the corresponding slit and advances it to the original position again.

また、相隣る各送り歯の間隙内にそれぞれ、切破された収納袋を脱離させる脱離部材が挿入してある。   In addition, a detaching member for detaching the cut storage bag is inserted in the gap between the adjacent feed dogs.

更に、前述した進退駆動部は、各破袋爪を適当な時間間隔で後退・前進させる退進駆動するようにしてある。   Further, the advancing / retreating drive unit described above is configured to retreat and drive the bag breaking pawls back and forth at appropriate time intervals.

次に、本発明に係る破袋機を図面に基づいて詳述する。   Next, the bag breaker according to the present invention will be described in detail with reference to the drawings.
