It is shown in a perspective view as seen diagonally from the rear. In addition, in the drawing, the front of the bottle compressor 10 is shown by an arrow FR, the left side of the bottle compressor 10 is shown by an arrow LH, and the upper part is shown by an arrow UP.
本実施形態に係るボトル圧縮機１０は、図４に示す略円筒状又は略矩形筒状の容器であるボトル１２（特にペットボトル）を圧縮するものである。 The bottle compressor 10 according to the present embodiment compresses a bottle 12 (particularly a plastic bottle) which is a substantially cylindrical or rectangular cylindrical container shown in FIG.
ボトル１２は、樹脂製にされて、可撓性を有しており、ボトル１２の先端以外は、有底筒状の本体部１２Ａにされている。ボトル１２の先端は、略円筒状の縮径部１２Ｂ（首部及び開口部）にされており、縮径部１２Ｂは、本体部１２Ａに比し径が小さくされている。また、本体部１２Ａ外周の周方向全体には、筒形フィルム状のラベル１４が装着されている。 The bottle 12 is made of resin and has flexibility, and the portion other than the tip of the bottle 12 is formed into a bottomed cylindrical body portion 12A. The tip of the bottle 12 is formed into a substantially cylindrical reduced-diameter portion 12B (neck and opening), and the reduced-diameter portion 12B has a smaller diameter than the main body portion 12A. Further, a cylindrical film-like label 14 is attached to the entire circumferential direction of the outer periphery of the main body portion 12A.
縮径部１２Ｂには、蓋部を構成する有底円筒状のキャップ１６が着脱可能にされており、縮径部１２Ｂにキャップ１６が装着（特に螺合）されてボトル１２が封止される（ボトル１２内が閉塞される）と共に、縮径部１２Ｂからキャップ１６が離脱されてボトル１２が開封される（ボトル１２内が開放される）。キャップ１６のボトル１２基端側には、蓋部を構成する円筒状のリング１６Ａが配置されており、リング１６Ａは、縮径部１２Ｂに係止されている。ボトル１２が一度も開封されていない際（縮径部１２Ｂからキャップ１６が一度も離脱されてない際）には、リング１６Ａがキャップ１６と一体にされており、ボトル１２が初めて開封される際（縮径部１２Ｂからキャップ１６が初めて離脱される際）に、リング１６Ａが、縮径部１２Ｂへの係止によって、キャップ１６から分離される。 A bottomed cylindrical cap 16 constituting a lid is removably attached to the reduced diameter portion 12B, and the bottle 12 is sealed by attaching (particularly screwing) the cap 16 to the reduced diameter portion 12B. At the same time (the inside of the bottle 12 is closed), the cap 16 is removed from the reduced diameter portion 12B and the bottle 12 is opened (the inside of the bottle 12 is opened). A cylindrical ring 16A constituting a lid portion is disposed on the base end side of the bottle 12 of the cap 16, and the ring 16A is locked to the reduced diameter portion 12B. When the bottle 12 has never been opened (when the cap 16 has never been removed from the reduced diameter portion 12B), the ring 16A is integrated with the cap 16, and when the bottle 12 is opened for the first time, the ring 16A is integrated with the cap 16. (When the cap 16 is removed from the reduced diameter portion 12B for the first time), the ring 16A is separated from the cap 16 by being locked to the reduced diameter portion 12B.
また、ボトル圧縮機１０に供給されるボトル１２は、例えば、産業廃棄物としてのものが想定されており、ボトル１２の縮径部１２Ｂにキャップ１６が装着されていても装着されていなくてもよく、ボトル１２に液体が収容（例えば残留）されていても収容されていなくてもよい。 Further, the bottle 12 supplied to the bottle compressor 10 is assumed to be, for example, industrial waste, and whether or not the cap 16 is attached to the reduced diameter portion 12B of the bottle 12 is not applicable. Often, the bottle 12 may or may not contain (e.g., residual) liquid.

Therefore, the bottle 12 is introduced into the input hopper from the upper opening of the input hopper and supplied to the bottle compressor 10.
図１の（Ａ）及び（Ｂ）、図２に示す如く、ボトル圧縮機１０には、略矩形筒状の圧縮筒１８が設けられており、圧縮筒１８の上側には、投入ホッパが支持されている。圧縮筒１８内は、投入ホッパ内に連通されており、投入ホッパ内に投入されたボトル１２は、圧縮筒１８内に流下（供給）される。 As shown in FIGS. 1A and 1B and FIG. 2, the bottle compressor 10 is provided with a compression cylinder 18 having a substantially rectangular cylindrical shape, and an input hopper is supported on the upper side of the compression cylinder 18. has been done. The inside of the compression cylinder 18 is communicated with the inside of the input hopper, and the bottle 12 thrown into the input hopper is flowed (supplied) into the compression cylinder 18 .
圧縮筒１８内には、回転体としての中空円柱状の圧縮ロール２０が一対配置されており、圧縮ロール２０は、圧縮筒１８内に回転可能に支持されている。圧縮ロール２０の軸方向は、左右方向に平行に配置されており、一対の圧縮ロール２０は、前後方向に並べられている。一対の圧縮ロール２０は、互いに機械的に接続されると共に、一方の圧縮ロール２０には、駆動装置としてのモータ（図示省略）が機械的に接続されており、モータが駆動されることで、一対の圧縮ロール２０が回転される。この際、一対の圧縮ロール２０は、互いに反対方向に同一速度で回転されて、それぞれの上部が間の隙間へ向かう方向に回転される。 A pair of hollow cylindrical compression rolls 20 serving as rotating bodies are disposed within the compression cylinder 18 , and the compression rolls 20 are rotatably supported within the compression cylinder 18 . The axial direction of the compression rolls 20 is arranged parallel to the left-right direction, and the pair of compression rolls 20 are arranged in the front-back direction. The pair of compression rolls 20 are mechanically connected to each other, and a motor (not shown) as a driving device is mechanically connected to one of the compression rolls 20, and when the motor is driven, A pair of compression rolls 20 are rotated. At this time, the pair of compression rolls 20 are rotated in opposite directions at the same speed, and the upper portions of each are rotated in a direction toward the gap between them.
前側（一方）の圧縮ロール２０の周面には、追加突出部としての矩形柱状の第１突起２２が複数（本実施形態では８個）固定されており、第１突起２２は、圧縮ロール２０の径方向外方に突出されると共に、突出端面が圧縮ロール２０の径方向に垂直に配置されている。第１突起２２は、圧縮ロール２０の軸方向全体において圧縮ロール２０の軸方向に平行に配置されており、複数の第１突起２２は、圧縮ロール２０の周方向に等間隔に配置されている。第１突起２２には、突刺部としての略円柱状の圧縮ピン２４が複数（本実施形態では３個）固定されており、圧縮ピン２４は、第１突起２２から圧縮ロール２０の径方向外方に突出されている。圧縮ピン２４の突出先端部は、円錐状にされており、複数の圧縮ピン２４は、圧縮ロール２０の軸方向に等間隔に配置されている。 A plurality of rectangular columnar first protrusions 22 (eight in this embodiment) as additional protrusions are fixed to the circumferential surface of the front (one) compression roll 20. The compression roll 20 protrudes outward in the radial direction, and the protruding end surface is arranged perpendicularly to the radial direction of the compression roll 20 . The first projections 22 are arranged parallel to the axial direction of the compression roll 20 throughout the axial direction of the compression roll 20, and the plurality of first projections 22 are arranged at equal intervals in the circumferential direction of the compression roll 20. . A plurality of substantially cylindrical compression pins 24 (three in this embodiment) are fixed to the first protrusion 22 as protrusions. It is protruding towards the side. The protruding tip of the compression pin 24 has a conical shape, and the plurality of compression pins 24 are arranged at equal intervals in the axial direction of the compression roll 20.
後側（他方）の圧縮ロール２０の周面には、突出部としての矩形柱状の第２突起２６が複数（本実施形態では８個）固定されており、第２突起２６は、圧縮ロール２０の径方向外方に突出されると共に、突出端面が圧縮ロール２０の径方向に垂直に配置されている。第２突起２６は、圧縮ロール２０の軸方向全体において圧縮ロール２０の軸方向に平行に配置されており、複数の第２突起２６は、圧縮ロール２０の周方向に等間隔に配置されている。また、第２突起２６の突出寸法は、第１突起２２の突出寸法に比し大きくされている。 A plurality of rectangular columnar second protrusions 26 (eight in this embodiment) as protrusions are fixed to the circumferential surface of the rear (other) compression roll 20. The compression roll 20 protrudes outward in the radial direction, and the protruding end surface is arranged perpendicularly to the radial direction of the compression roll 20 . The second projections 26 are arranged parallel to the axial direction of the compression roll 20 throughout the axial direction of the compression roll 20, and the plurality of second projections 26 are arranged at equal intervals in the circumferential direction of the compression roll 20. . Furthermore, the protrusion dimension of the second protrusion 26 is larger than the protrusion dimension of the first protrusion 22.
一対の圧縮ロール２０が回転される際には、前側の圧縮ロール２０の第１突起２２及び圧縮ピン２４が後側の圧縮ロール２０の周面に第２突起２６間の周方向中央位置において最も接近される（図１（Ａ）参照）と共に、後側の圧縮ロール２０の第２突起２６が前側の圧縮ロール２０の周面に第１突起２２間（圧縮ピン２４間）の周方向中央位置において最も接近される（図１（Ｂ）参照）。後側の圧縮ロール２０の周面との第１突起２２の最小クリアランス（最小隙間寸法）は、１０ｍｍ以上１５ｍｍ以下にされており、後側の圧縮ロール２０の周面との圧縮ピン２４の最小クリアランス（最小隙間寸法）は、略０ｍｍにされている（図１（Ａ）参照）。前側の圧縮ロール２０の周面との第２突起２６の最小クリアランス（最小隙間寸法）は、１０ｍｍ未満（例えば２ｍｍ以上３ｍｍ以下）にされている（図１（Ｂ）参照）。 When the pair of compression rolls 20 are rotated, the first protrusion 22 and compression pin 24 of the front compression roll 20 are placed on the circumferential surface of the rear compression roll 20 at the center position in the circumferential direction between the second protrusions 26. As the second protrusion 26 of the rear compression roll 20 approaches the circumferential surface of the front compression roll 20 (see FIG. 1(A)), the second protrusion 26 of the rear compression roll 20 touches the circumferential center position between the first protrusions 22 (between the compression pins 24). (see FIG. 1(B)). The minimum clearance (minimum gap dimension) of the first protrusion 22 with the circumferential surface of the rear compression roll 20 is set to 10 mm or more and 15 mm or less, and the minimum clearance of the compression pin 24 with the circumferential surface of the rear compression roll 20 is set to 10 mm or more and 15 mm or less. The clearance (minimum gap dimension) is approximately 0 mm (see FIG. 1(A)). The minimum clearance (minimum gap dimension) of the second protrusion 26 with the circumferential surface of the front compression roll 20 is less than 10 mm (for example, 2 mm or more and 3 mm or less) (see FIG. 1(B)).
また、圧縮筒１８の下側には、後処理部２８が設けられている。 Furthermore, a post-processing section 28 is provided below the compression cylinder 18 .
次に、本実施形態の作用を説明する。 Next, the operation of this embodiment will be explained.
以上の構成のボトル圧縮機１０では、投入ホッパ内に投入されたボトル１２が、圧縮筒１８内に流下されて、一対の圧縮ロール２０の上側に流下される。さらに、一対の圧縮ロール２０が回転されることで、前側の圧縮ロール２０の第１突起２２及び圧縮ピン２４と後側の圧縮ロール２０の第２突起２６とによってボトル１２が一対の圧縮ロール２０間に搬送されて、ボトル１２が一対の圧縮ロール２０間（特に第１突起２２と後側の圧縮ロール２０の周面との間及び第２突起２６と前側の圧縮ロール２０の周面との間）で圧縮（特に圧壊）されると共に、ボトル１２に圧縮ピン２４が突き刺さる（特に貫通される）。これにより、ボトル１２に圧縮ピン２４により孔が形成されて、ボトル１２から空気が排出されることで、ボトル１２が効果的に圧縮されて、ボトル１２から液体（残液）が排出される。しかも、ボトル１２からキャップ１６及びリング１６Ａが離脱される。 In the bottle compressor 10 having the above configuration, the bottle 12 charged into the input hopper is flowed down into the compression cylinder 18 and then flowed down onto the upper side of the pair of compression rolls 20 . Further, as the pair of compression rolls 20 are rotated, the bottle 12 is moved to the pair of compression rolls 20 by the first protrusion 22 and compression pin 24 of the front compression roll 20 and the second protrusion 26 of the rear compression roll 20. The bottle 12 is conveyed between the pair of compression rolls 20 (particularly between the first protrusion 22 and the circumferential surface of the rear compression roll 20 and between the second protrusion 26 and the circumference of the front compression roll 20). At the same time, the bottle 12 is compressed (particularly crushed) and the compression pin 24 is thrust (particularly penetrated) into the bottle 12. As a result, a hole is formed in the bottle 12 by the compression pin 24 and air is discharged from the bottle 12, whereby the bottle 12 is effectively compressed and liquid (residual liquid) is discharged from the bottle 12. Moreover, the cap 16 and ring 16A are removed from the bottle 12.
そして、一対の圧縮ロール２０間からボトル１２（ラベル１４を含む）、キャップ１６、リング１６Ａ及び液体が後処理部２８に流下（供給）される。後処理部２８では、上記特許文献１と同様にボトル１２からラベル１４が剥離されて選別され、又は、上記特許文献２と同様にボトル１２からキャップ１６、リング１６Ａ及び液体が選別される。 Then, the bottle 12 (including the label 14), the cap 16, the ring 16A, and the liquid flow down (supply) to the post-processing section 28 from between the pair of compression rolls 20. In the post-processing section 28, the label 14 is peeled off and sorted from the bottle 12 as in Patent Document 1, or the cap 16, ring 16A, and liquid are separated from the bottle 12 as in Patent Document 2.
ここで、後側の圧縮ロール２０の第２突起２６が、圧縮ピン２４を設けられずに、前側の圧縮ロール２０の周面と対向されて、ボトル１２が圧縮される（図１（Ｂ）参照）。このため、第２突起２６と前側の圧縮ロール２０の周面との間でボトル１２を効果的に圧縮でき、ボトル１２から液体を効果的に排出できる。これにより、後処理部２８においてボトル１２に液体が付着することを抑制でき、かつ、後処理部２８内が液体により腐食することを抑制できて、後処理部２８を長寿命化できると共に、後処理部２８のランニングコストを削減できる。しかも、第２突起２６に圧縮ピン２４が設けられないことで、消耗部品である圧縮ピン２４を少なくでき、ボトル圧縮機１０のランニングコストを削減できる。 Here, the second protrusion 26 of the rear compression roll 20 is opposed to the circumferential surface of the front compression roll 20 without the compression pin 24, and the bottle 12 is compressed (FIG. 1(B) reference). Therefore, the bottle 12 can be effectively compressed between the second protrusion 26 and the circumferential surface of the front compression roll 20, and the liquid can be effectively discharged from the bottle 12. As a result, it is possible to prevent liquid from adhering to the bottle 12 in the post-processing section 28, and also to prevent the inside of the post-processing section 28 from being corroded by the liquid. The running cost of the processing section 28 can be reduced. Moreover, since the compression pin 24 is not provided on the second protrusion 26, the number of compression pins 24, which are consumable parts, can be reduced, and the running cost of the bottle compressor 10 can be reduced.
また、前側の圧縮ロール２０の第１突起２２から圧縮ピン２４が突出されている。このため、圧縮ピン２４がボトル１２に突き刺さる際に、第１突起２２と後側の圧縮ロール２０の周面との間でボトル１２を圧縮できて、ボトル１２から液体を排出できる（図１（Ａ）参照）。 Moreover, a compression pin 24 protrudes from the first protrusion 22 of the compression roll 20 on the front side. Therefore, when the compression pin 24 pierces the bottle 12, the bottle 12 can be compressed between the first protrusion 22 and the circumferential surface of the compression roll 20 on the rear side, and the liquid can be discharged from the bottle 12 (see FIG. See A).
さらに、後側の圧縮ロール２０からの第２突起２６の突出寸法が前側の圧縮ロール２０からの第１突起２２の突出寸法に比し大きくされており、前側の圧縮ロール２０の周面との第２突起２６の最小クリアランスが後側の圧縮ロール２０の周面との第１突起２２の最小クリアランスに比し小さくされる。このため、第２突起２６と前側の圧縮ロール２０の周面との間でボトル１２を一層効果的に圧縮でき、ボトル１２から液体を一層効果的に排出できる。 Further, the protrusion dimension of the second protrusion 26 from the rear compression roll 20 is larger than the protrusion dimension of the first protrusion 22 from the front compression roll 20, so that the protrusion dimension of the second protrusion 26 from the rear compression roll 20 is larger than the protrusion dimension of the first protrusion 22 from the front compression roll 20. The minimum clearance of the second protrusion 26 is made smaller than the minimum clearance of the first protrusion 22 with the peripheral surface of the compression roll 20 on the rear side. Therefore, the bottle 12 can be compressed more effectively between the second protrusion 26 and the circumferential surface of the front compression roll 20, and the liquid can be discharged from the bottle 12 more effectively.
しかも、第１突起２２が後側の圧縮ロール２０の周面に最も接近される際には、第１突起２２と後側の圧縮ロール２０の周面とのクリアランスが大きくされると共に、第２突起２６が前側の圧縮ロール２０の周面に最も接近される際には、第２突起２６と前側の圧縮ロール２０の周面とのクリアランスが小さくされる。このため、ボトル１２が一対の圧縮ロール２０間で圧縮される際には、一対の圧縮ロール２０間のクリアランスが一定周期で変動することで（図３参照）、ボトル１２の圧縮量を一定周期で変動できて、ボトル１２から液体を効率的に排出できる。 Moreover, when the first protrusion 22 approaches the circumferential surface of the rear compression roll 20, the clearance between the first protrusion 22 and the circumference of the rear compression roll 20 is increased, and the second When the protrusion 26 is closest to the circumferential surface of the front compression roll 20, the clearance between the second protrusion 26 and the circumference of the front compression roll 20 is reduced. Therefore, when the bottle 12 is compressed between the pair of compression rolls 20, the clearance between the pair of compression rolls 20 changes at a constant cycle (see FIG. 3), so that the amount of compression of the bottle 12 is controlled at a constant cycle. This allows the liquid to be efficiently discharged from the bottle 12.
さらに、ボトル１２が第１突起２２と後側の圧縮ロール２０の周面との間及び第２突起２６と前側の圧縮ロール２０の周面との間で同時に圧縮されることで、ボトル１２を側面視略Ｚ字状に大きく絞る（捩る）ことができ、ボトル１２から液体を効率的に排出できる。 Furthermore, the bottle 12 is compressed simultaneously between the first protrusion 22 and the circumferential surface of the rear compression roll 20 and between the second protrusion 26 and the circumference of the front compression roll 20. It can be largely squeezed (twisted) into a substantially Z-shape when viewed from the side, and the liquid can be efficiently discharged from the bottle 12.
また、一対の圧縮ロール２０の上側に異物（例えばネジ類）が流下された場合には、異物が第１突起２２と後側の圧縮ロール２０の周面との隙間を通過できて、一対の圧縮ロール２０間に異物を噛み込むことを抑制できる。このため、一対の圧縮ロール２０を駆動するモータの負荷が上昇することを抑制できると共に、当該モータの容量を大きくする必要性を低くできる。 Further, when a foreign object (for example, a screw) is flown down to the upper side of the pair of compression rolls 20, the foreign object can pass through the gap between the first protrusion 22 and the circumferential surface of the rear compression roll 20, and It is possible to prevent foreign matter from getting caught between the compression rolls 20. Therefore, it is possible to suppress an increase in the load on the motor that drives the pair of compression rolls 20, and to reduce the need to increase the capacity of the motor.
