Description

  The present invention relates to an apparatus for cutting a cap part and a label so as to be separable from a main body when a commercially available plastic bottle such as a PET bottle is collected.

  In recent years, a recycling system for PET (PET: polyethylene terephthalate) bottles collected from homes and the like is becoming widespread. Usually, these PET bottles are crushed and flaked and made industrially recyclable materials.

  Almost all products of such plastic bottles have a cap part made of a material different from that of the bottle body and a label wound around the body. The cap part is not only the cap itself but also the male threaded part where the cap is fitted is often made of a different material, and different materials are included even if the cap is not fitted when collecting the bottle. Become. Therefore, it is necessary to separate the cap part and the label at any stage before recycling.

  For example, the cap part and the label are separated from the main body material by performing a process such as wind sorting or specific gravity sorting several times after the cap part and the label are attached to the bottle body and crushed together. However, this method causes an increase in the number of processes and components until the recycled material is obtained, and the cost burden is large.

  In order to simplify the components and improve the efficiency of the entire process, it is necessary to separate the cap portion and the label made of different materials at the time of collection before crushing or at the time of accumulation. Of course, all this is done manually, which is a cumbersome and laborious method.

  Therefore, at present, a collection device has been developed that, when collecting a plastic bottle, separates the cap portion and the label from the bottle body. For example, a plastic bottle is transported to a predetermined position in a collection box, fixed in position, a label is cut with a rotary blade and removed with a suction device, and the top of the bottle including the cap is cut with another rotary blade. is there. In such a recovery device, there is a recovery device that includes a crusher in the recovery box, and crushes the bottle body from which the cap portion and the label are removed, and performs flaking (for example, see Patent Document 1).

JP 2001-138327 A

  However, the conventional collection device as described above has a complicated structure that requires a large number of mechanisms such as a PET bottle transport mechanism and a driving device for each rotary blade. There was nothing suitable for practical use, such as storefronts and storefronts.

  In view of the above problems, an object of the present invention is a plastic bottle that has a simpler structure than conventional ones, and can cut and separate a cap part and a label made of different materials from the bottle body when collecting commercially available plastic bottles such as PET bottles. It is to provide a cutting and separating apparatus.

In order to achieve the above object, a plastic bottle cutting / separating apparatus according to the first aspect of the present invention cuts and separates a cap part and a label from a plastic bottle put into the apparatus main body and accommodates it in a foreign substance storage chamber and a bottle main body. In plastic bottle cutting and sorting device that collects
A holding mechanism having a suction nozzle for sucking and holding a plastic bottle put in from a charging port via a label on both left and right sides at a predetermined position, and a nozzle drive unit for moving the suction nozzle forward and backward to the suction position; ,
A horizontal cutting blade that abuts the plastic bottle positioned and held by the holding mechanism along a direction crossing between the cap screwing portion and the bottle shoulder, and is orthogonal to the horizontal cutting blade, A cutting blade portion having a substantially T-shaped cross section having a vertical cutting blade that is in contact with the bottom of the bottle from the contact position of the cutting blade along the central longitudinal direction of the bottle body;
The retraction position in which the cutting blade is retracted in the direction away from the plastic bottle in the holding state, the vertical cutting blade completes dividing the bottle body into left and right, and the horizontal cutting blade holds the cap portion. A drive mechanism that reciprocates linearly, for example, between the cutting position that is advanced until it is separated from the bottle body;
After separating the bottle body at the cutting position and separating the cap part, the cap part is selectively led to a foreign substance chute that communicates with the foreign substance storage chamber before the cutting blade part is retracted to the retracted position, and the cutting blade part The bottle body falling away from the label adsorbed by the holding mechanism simultaneously with the retraction of the bottle body is selectively guided to a bottle chute that communicates with the bottle collection chamber, and after the bottle body is dropped, the suction of the holding mechanism is released. Chute switching means for guiding the falling label to the foreign object chute,
It is equipped with.

  Further, the plastic bottle cutting and separating device according to the invention of claim 2 is the crusher for crushing the bottle body falling at the upstream portion of the bottle recovery chamber in the plastic bottle cutting and separating device of claim 1. Is further provided.

  According to a third aspect of the present invention, there is provided the plastic bottle cutting / separating apparatus according to the first or second aspect, wherein the holding mechanism is in a suction state in which air is sucked from the suction nozzle. It can switch to the air blow state which blows off air, It is characterized by the above-mentioned.

  In the plastic bottle cutting / separating apparatus of the present invention, the bottle purchased from the insertion port is suction-held on both the left and right sides by the suction nozzle of the holding mechanism and positioned, and the horizontal cutting blade for cutting the cap portion and the bottle body are cut. For cutting the cap part, the label and the cap part are separated from the bottle body at once by advancing the cutting blade part having a substantially T-shaped cross section consisting of the vertical cutting blade for the bottle with respect to the bottle. Compared to the conventional device that drives each rotary blade for label cutting with the respective drive system, the device configuration is simple, and not only low cost but also low noise can be achieved, and there is an effect that it is suitable for practical use. .

  The present invention is a plastic bottle cutting / separating apparatus that cuts and separates a cap part and a label from a plastic bottle put into the apparatus main body and stores it in a foreign substance storage chamber and collects the bottle main body in a collection chamber. In a state where the plastic bottle is sucked and held by the suction nozzle of the holding mechanism through the labels on both the left and right sides, the plastic bottle is applied along the direction crossing between the cap side tip and the bottle shoulder. A substantially T-shaped cross section having a transverse cutting blade in contact and a longitudinal cutting blade that is orthogonal to the transverse cutting blade and abuts along the central longitudinal direction of the bottle body from the contact position of the transverse cutting blade to the bottom of the bottle The cutting blade portion is advanced by the drive mechanism, whereby the cap portion and the bottle body are cut simultaneously by a simple device configuration having one drive mechanism.

  At the time of this cutting, if the fall object is guided only to the foreign substance chute communicated with the foreign substance storage chamber by the chute switching means, the cap part can be dropped and collected into the foreign substance storage room, and when the bottle body is divided, Since the label is also cut, if the switching is made so that the fallen object is guided only to the bottle chute that communicates with the bottle collection chamber, the cutting blade portion 3 is retracted by the drive mechanism and the support to the bottle body B is lost. At the same time, the bottle body that has been divided leaving only the label held by the suction nozzle falls and is collected in the collection chamber. If the fall object is guided only to the foreign matter chute by the chute switching means and the suction by the suction nozzle is released, the label is dropped and stored in the foreign substance storage chamber.

  As described above, according to the apparatus of the present invention, when cutting the cap part, the bottle body, and the label, the cap part, the label body, and the bottle main body are moved by a series of operations such as the advancement and retraction of the cutting blade part by one drive mechanism. Can be performed substantially simultaneously. In addition, by switching the chute switching means in conjunction with the forward / backward movement of the cutting blade, the falling cap and label are selectively collected into the foreign substance storage chamber and the bottle body is selectively collected into the collection chamber. And can be separated.

  As the chute switching means, for example, a foreign substance chute that communicates with the foreign substance storage chamber and a bottle chute that communicates with the bottle collection chamber are merged below the upstream cutting portion, and a door member provided at this confluence is opened on one chute It is simple to switch between a position where the other is exposed and the other is closed, and a position where the other is closed and the other chute opening is exposed.

  In order to smoothly recover the cap part, it is desirable that the bottle is held downward so that the cap part is at the lower end during cutting, and the cutting blade part is arranged in an inverted T shape. In addition, the normal bottle input port is located above the bottle holding position. In this case, the input direction from the cap part may be set as the input direction to the input port.

  If a crusher is installed in the upstream part of the bottle collection chamber, for example, the downstream part of the chute that leads to the bottle collection chamber, the falling bottle body is crushed into flakes and collected in the bottle collection chamber. From the cutting and separation of plastic bottles to the flaking of recycled materials can be performed continuously in the same apparatus, and the high collection room space can be efficiently used without the collection bottles becoming bulky.

  In addition, the label suction state by the suction nozzle of the holding mechanism is released by stopping air suction and can be dropped, but when dropped from the nozzle suction position, the label that does not fall straight falls down in the outer periphery of the chute opening. It is also conceivable that it is not collected in the foreign substance storage chamber. Therefore, if the holding mechanism can be switched from the suction state of the suction nozzle to the air blow state in which air is blown out, the air can be blown simultaneously with the suction stop so that the label can be pushed out toward the center of the chute opening and dropped. Label collection into the storage chamber can be ensured.

  This device, which has a simple configuration as described above, and can separate and collect the bottle body of a plastic bottle and the cap part / label of a different material chamber well, can reduce the size, noise, and cost of the design, It is suitable for practical use as a store / front store type. In addition, the apparatus may further include a disposal chute that can discard a cap, residual liquid, and the like before the bottle is charged.

  Also, when holding the bottle by the holding mechanism, in order to make positioning in the vertical direction more accurate, the bottom plate with which the tip of the cap abuts can be moved back and forth along the horizontal direction above the chute opening. It is preferable to do. Such a bottom plate portion can substantially function as a gate for opening and closing the chute opening. The drive mechanism for moving the door member and gate of the chute switching means as described above can be easily moved and opened / closed between two predetermined positions, for example, using a mechanism such as a hydraulic cylinder or an air cylinder. Anything is fine.

  In addition, in the case of a store / store-front type apparatus, from the suction holding of the bottle to the cutting by the cutting blade, the switching of the gate switching means, and the crushing process can be automatically processed in a series of steps by linking each drive mechanism. It is easy to use and desirable. At this time, the processing process can be started easily by the user, for example, by using a switch on the operation panel provided on the outer surface of the apparatus or by using a switch for opening and closing the inlet door when the bottle is inserted. preferable.

  The plastic bottle in the present invention is of a standard size containing a commercially available beverage, and a polyethylene terephthalate (PET) bottle called a so-called PET bottle is a main object. Even a bottle made of a plastic member is effective. Usually, such bottles have a plurality of capacity sizes such as 350 mL, 500 mL, 1 L, and 2 L. However, since the shapes are almost uniform for each capacity, the apparatus of the present invention is also set for each capacity. Can be prepared.

  As an embodiment of the present invention, a store-placed plastic bottle cutting and sorting apparatus is shown in FIGS. FIG. 1 is a schematic configuration diagram mainly showing a cutting region of a main body structure in a housing of the apparatus, wherein (a) is a side view, (b) is an upper plan view, and (c) is an AA of (a). FIG. FIG. 2 is a perspective view of a cut portion of the apparatus. FIG. 3 is a conceptual diagram showing a plastic bottle cutting / separating process by the apparatus, and FIG. 4 is a flowchart for explaining a flow of the plastic bottle cutting / sorting process by the apparatus.

  The cutting and separating apparatus includes a cutting area provided in the upper part, a recovery area of the bottle collecting chamber R1 provided in the lower part and a foreign substance storage room R2 such as a cap and a label, and a recovery area from both cutting mechanisms. Mainly composed of a chute switching means 11 for selectively separating the bottle main body and the foreign matter to the chute for bottle 9a and the chute for foreign matter 9b communicating with the chamber, respectively. The bottle recovery chamber R1 and the foreign matter storage chamber R2 are configured by containers that can be taken in and out of the main body from outside the apparatus.

  As shown in FIG. 1, the cutting region is a pair of left and right adsorbers, as shown in FIG. 1, with respect to a plastic bottle P placed in an inverted state with the opening end (cap portion C) facing downward. A holding mechanism 1 is provided that sucks and holds both side surfaces of the bottle P via a label L by air suction from the nozzles (2a, 2b). In this holding mechanism 1, centering is performed at a predetermined position for cutting when the suction pad 3 at the tip of the suction nozzle abuts and holds the plastic bottle P from both the left and right sides for suction holding, and accurate positioning is performed. Was to be completed. The holding mechanism 1 can perform not only air suction from the suction nozzles (2a, 2b) but also air blow by air blowing.

  In the present embodiment, the cylindrical frame member 4 is provided immediately below the insertion port to guide the PET bottle P to an area where it can be sucked and held. The frame member 4 has a substantially quadrangular prism shape that can accommodate the PET bottle P as a whole, and as shown in FIG. 2, the left and right side walls pass through the suction pad 3 for contacting the PET bottle P. Is formed, and a substantially inverted T-shaped opening T is formed on the front wall to permit the moving passage of a cutting blade 5 for cutting a plastic bottle P, which will be described later.

  Further, as shown in FIG. 3, a gate 8 serving as a bottom plate portion is provided at the lower end position of the frame member 4 so as to be able to reciprocate in the horizontal direction, and the gate 8 is positioned as the bottom plate portion of the frame member 4. In this state, the leading end of the plastic bottle P introduced into the frame member 4 comes into contact with it, so that the vertical positioning is more accurately performed during suction holding. The reciprocating movement of the gate 8 substantially opens and closes the chute opening below the gate 8.

  As described above, the mechanism for cutting the plastic bottle P sucked and held at the predetermined position by the holding mechanism 1 is a horizontal cutting blade that abuts along the direction crossing between the cap side tip and the bottle shoulder. 6 and a vertical cutting blade 7 that is orthogonal to the horizontal cutting blade 6 and that contacts the bottle body (main body) B along the central longitudinal direction from the contact position of the horizontal cutting blade 6 to the bottom of the bottle. The reverse T-shaped cutting blade 5 is moved forward and backward by a drive mechanism.

  That is, the plastic bottle P positioned in the frame member 4 is cut by advancing the cutting blade 5 until it passes through the opening T in the front wall of the frame member 4 and reaches the back wall of the frame member 4. When the cap C and the bottle body B are separated, the bottle body B is divided into left and right together with the label L.

  As shown in FIG. 3, a bottle collection chamber R1 for collecting the bottle body B and a foreign substance storage chamber R2 for containing foreign substances such as a cap C and a label L are installed in the collection area below the apparatus. A bottle chute 9a and a foreign matter chute 9b communicating with the chambers (R1, R2) extend from below the gate 8. These two chutes (9a, 9b) join at the upper part, and the chute opening is set at a position for receiving the fallen object from the lower end opening of the frame member 4 exposed in the opened state of the gate 8.

  A switching mechanism 11 serving as a chute switching unit is provided at the chute junction. This chute switching mechanism 11 has a position between the position where the door member 10 installed at the junction part exposes one chute opening and closes the other, and conversely the other one closes and exposes the other chute opening. It is made to rotate and move.

  Therefore, for example, if the door member 11 is rotated to a position where the bottle chute 9a is closed and the foreign substance chute 9b is opened using a driving mechanism such as a hydraulic cylinder or an air cylinder, the chute is opened in the open state of the gate 9. The foreign matter falling to the opening is accommodated in the foreign matter storage chamber R2 through the foreign matter chute 9b and is not mistakenly mixed with the bottle recovery chamber R1. Further, if the door member 11 is rotated in the reverse direction so as to close the foreign matter chute 9b and open the bottle chute 9a, the bottle body B which is divided and falls into the chute opening has the bottle chute 9a removed. It passes through the bottle collection chamber R2 and is not mistakenly mixed with the foreign substance storage chamber R2.

  As described above, in the state where the cutting blade portion 5 is advanced to the back wall of the frame member 4 in the suction holding state by the holding mechanism 1 and the plastic bottle P is cut, if the gate 8 is opened as it is, the horizontal cutting blade 6 Only the cap part C separated from the bottle body B naturally falls. Therefore, if the rotation position of the door member 10 is switched so that the foreign matter chute 9b is opened at this time, the cap portion C that has fallen into the chute opening is guided from the foreign matter chute 9b to the foreign matter storage chamber R2.

  Further, the bottle body B is divided into left and right parts by the advancement of the cutting blade part 5. At this time, since the label L is also cut, the cutting blade part 3 is retracted and released from the support to the bottle body B. Then, the bottle body B that has been divided leaving only the label L held by the suction nozzles (2a, 2b) falls.

  Therefore, if the rotation position of the door member 10 is switched so that the bottle chute 9 is in the open state before the cutting blade portion 3 is retracted, the bottle body B that has fallen into the chute opening is removed from the bottle chute 9a. Guided to the bottle collection chamber R1. In addition, the chute switching mechanism 11 switches to a state in which the door member 10 is opened so that the fallen object is guided only to the foreign matter chute 9b, releases the suction by the suction nozzles (2a, 2b), switches to the air blowing, and is in an air blow state Then, after the label L is pushed out toward the center of the chute opening, it falls into the foreign substance chute 9b without falling down to the outer periphery of the chute opening and is accommodated in the foreign substance accommodation chamber R2.

  Furthermore, in this example, the crusher 15 was installed at a position upstream from the bottle recovery chamber R2. Therefore, since the bottle body B sent through the bottle chute 9a is flaked by the crusher 15 and then collected in the bottle collection chamber R2, the bottle body B is collected in a substantially bottle shape although it is divided. Compared with the case where it does, it is not bulky, the space utilization efficiency of bottle collection room R2 is remarkably high, and the whole cutting | disconnection classification efficiency improves.

  In the plastic bottle cutting / separating apparatus having the above-described configuration, the cutting blade 5 having a substantially T-shaped cross section is moved forward with respect to the plastic bottle P by one drive mechanism, whereby the label L and the cap C are separated. Since the substantial cutting and separation from the bottle main body B are performed at once, the apparatus configuration is simpler than the conventional apparatus that drives the rotary blades for cutting the cap part and for cutting the label by respective drive systems. In addition, low noise as well as low cost can be achieved, which is suitable for practical use.

  In such a plastic bottle cutting and separating apparatus, if the drive from the holding mechanism 1 to the gate 8, the chute switching mechanism 11 and the crusher 15 are interlocked, as shown in the flowchart of FIG. From the recovery of the flaked material of the bottle body B and the recovery of the foreign matter such as the cap C and the label L can be efficiently completed in a series of continuous processes.

  For example, a configuration in which driving is started by a switch provided on the operation panel on the housing surface of the apparatus main body, or after the inlet port 20 is opened (100) and the PET bottle P is introduced (101), the inlet port 20 is closed. In the case of (102), there is a configuration in which a series of driving is started with this as a starting point.

  In any case, at the start of driving, the gate 8 is in a position where the lower end of the frame member 4 is closed in a bottom plate shape, the suction nozzles (2a, 2b) and the suction pad 3 are in a standby position separated from each other, and the cutting blade portion The initial setting is a state in which all drive mechanisms are stopped at the standby position 5 also retracted.

  In this initial setting, the holding mechanism 1 is first driven when the plastic bottle P, which has been thrown downward, is closed in the state in which the plastic bottle P is housed in the frame member 4 with the gate 8 being in contact with the tip portion. By moving the suction nozzles (2a, 2b) forward (103), the suction pads (3a, 2b) are moved while the suction pads 3 are moved closer to each other so that the PET bottle P is in contact with and sandwiched between the left and right sides. Start air suction by. By such driving of the holding mechanism 1, the centering positioning and suction holding of the plastic bottle P are completed simultaneously (104).

  At the same time that this suction holding state is obtained, advancement by the drive mechanism of the cutting blade part 5 is started, and the horizontal cutting blade 6 is moved forward by the cutting blade part 5 until it reaches the back wall from the opening T of the front wall of the frame member 4. The cutting process is completed (105), in which the cap part C is separated and the bottle body B is divided by the longitudinal cutting blade 7 for each label L. When this cutting process is completed, the door member 10 is rotated by driving the chute switching mechanism 11 so that the foreign matter chute 9b is opened (106). Therefore, when the lower end of the frame member 4 is opened by the movement of the gate 8, the cap portion C falls from the chute opening to the foreign matter chute 9b and is accommodated in the foreign matter accommodation chamber R2 (107).

  Subsequently, the chute switching mechanism 11 is driven to rotate the door member 10 to switch the bottle chute 9a to the open state (108). Then, the cut bottle body B is dropped by moving the cutting blade part 5 back to the standby position (109). Simultaneously with the retraction of the cutting blade 5, the crusher 15 is activated. Accordingly, the dropped bottle body B is sent to the crusher 15 through the bottle chute 9a and crushed (110), and the flaked product is collected into the bottle collection chamber R2 (111).

  On the other hand, the label L remains in the suction holding state even after the bottle body B is dropped, but the chute switching mechanism 11 is driven again to rotate the door member 10 to switch the foreign matter chute 9b to the open state (113). . After this switching, the holding mechanism 1 stops air suction of the suction nozzles (2a, 2b) and simultaneously starts air blowing, whereby the label L is dropped into the chute opening and accommodated from the foreign matter chute 9b into the foreign matter storage chamber R2. (114). Thus, when the collection of the flaked material from the bottle and the collection of the label L are completed, the crusher 15 and the drive mechanism of the holding mechanism 1 are stopped, and the cutting and separating step is completed (115).

  The main body structure shown in the above embodiment has a simple appearance as shown in FIG. 5 and a housing H having an appropriate size for a store. (Which is led out to the storage chamber R2) and can be accommodated efficiently.

  The cutting / separating apparatus according to the present invention is not limited to an independent store / storefront, and the large-scale apparatus or large apparatus for intermediate processing companies is not limited to the above-described apparatus mechanism being integrated into an appropriately small housing. It can also be used for scale processing factories. For example, the main mechanism of the present invention can be incorporated into a processing line in a plastic bottle recycling factory so as to take part of a continuous processing step.

  Further, in the above-described embodiment, the case where a plastic bottle is targeted has been described. However, the cutting and separating apparatus according to the present invention separates a bottle body from a different label / cap portion in any plastic bottle. It can be applied when collecting separately.
