It is related with the used paper filter collection | recovery apparatus of the drink extractor which collect | recovers used used paper filters.

  2. Description of the Related Art Conventionally, as a coffee extractor that extracts coffee using coffee beans and filters it with a continuous paper filter, for example, the one disclosed in Patent Document 1 already filed by the present applicant is known. This coffee extractor is built in a cup-type vending machine, supplied with powdered coffee beans and hot water as raw materials, and attached to the bottom of the extractor body for extracting coffee. And a paper holder that rotatably supports the roll portion of the paper filter wound in a roll shape. The main body of the extractor includes a cylindrical cylinder from which coffee is extracted, a filter block provided below the cylinder so as to be movable up and down, a drive mechanism for driving the filter block up and down, and the like. Further, the paper filter supported by the paper holder is set so as to be guided from the front of the extractor main body to the rear through the cylinder and the filter block, and further hung from the extractor main body. The extractor body is provided with a drawing mechanism for pulling out the paper filter from the paper holder.

  In the above coffee extractor, since the paper holder that supports the paper filter is attached to the bottom of the extractor body, the overall height of the coffee extractor is relatively high. For this reason, when installing this coffee extractor inside a cup-type vending machine or a beverage dispenser, a vertically long and relatively large space is required. In addition, the extracted mash and the used paper filter generated by the coffee extraction and filtration by the coffee brewing machine are collected in a cocoon bucket as waste. However, since these extraction baskets and used paper filters are simply sent out from above and are housed in a mixture in the bucket, they are easily bulky in the bucket. For this reason, the waste storage efficiency in the coffee bucket is poor, and if a large number of coffees are to be sold, a coffee bucket with a relatively large height is required. Therefore, in addition to the large space for installing the coffee extractor described above, a large space for installing the coffee bucket is required inside the cup-type vending machine or beverage dispenser. As a result, the cup The height dimension of the vending machine and beverage dispenser will increase.

  The present invention has been made to solve the above-described problems, and can efficiently collect a used paper filter used for beverage filtration, and a space in which the paper filter is collected. It aims at providing the used paper filter collection | recovery apparatus of the drink extractor which can comprise the whole height of the drink extractor containing this compactly.

In order to achieve the above object, the invention according to claim 1 is used for filtration in a beverage extractor that extracts a beverage using raw materials and water and filters the extracted beverage through a continuous paper filter. A used paper filter collection device for a beverage extractor that collects used paper filters, a drive means, a support member provided on the lower side of an extractor body that performs extraction and filtration, and a bar shape extending in the left-right direction is formed in a is rotatably supported by the support member at both ends, by being rotatably driven by drive means, comprising a winding member for winding the used paper filter, a take-up member, the It is characterized in that the diameter is gradually reduced toward the center in the length direction .

According to this configuration, the support member is provided on the lower side of the main body of the extractor that performs beverage extraction and filtration, and the bar-shaped winding member extending in the left-right direction is freely rotatable at both ends of the support member. It is supported. And this winding member is rotated by the driving means to wind up the used paper filter used for filtering the beverage. A used paper filter can be efficiently collected. For this reason, it is not necessary to enlarge the space for collecting used paper filters more than necessary, and the overall height of the beverage extractor including the space can be configured compactly.
Moreover, generally, in the continuous paper filter used for the filtration of a drink, an extractant | flour tends to remain near the center of the width direction. For example, when a paper filter having an extractor attached thereto is repeatedly wound using a winding member having a constant cross-section, the paper filter has the extractor interposed between the paper filters overlapped by winding. The diameter near the center in the width direction is larger than both ends. For this reason, it is necessary to increase the space for collecting the used paper filter, and when the paper filter is discarded, it becomes difficult to handle compared to a simple cylindrical filter. On the other hand, according to the present invention, since the diameter of the winding member gradually decreases toward the center in the length direction, even if an extraction rod is interposed between the wound paper filters. It is possible to suppress an increase in the diameter near the center in the width direction. Thereby, it is not necessary to enlarge the space for collecting used paper filters, and handling at the time of disposal of the paper filters can be facilitated.

  The invention according to claim 2 is the used paper filter collection device of the beverage extractor according to claim 1, wherein the driving means is used by being driven by the driving source after the single driving source and after filtration. The used paper filter is sent to the winding member side, and the unused paper filter following the used paper filter is sent to the extractor body. In order to wind up the used paper filter, a winding member driving mechanism for rotating the winding member is provided.

  According to this configuration, the used paper filter is sent out to the take-up member side and the unused paper filter is sent out to the extractor main body by driving the paper feed mechanism after filtration. Further, when the winding member driving mechanism is driven together with the paper feeding mechanism, the winding member is rotationally driven, and the used paper filter is wound around the winding member. In this way, the used paper filter is wound up while the paper filter is being fed out by the paper feeding mechanism and the winding member driving mechanism, so that stable feeding and winding of the paper filter can be ensured. Further, since the paper feeding mechanism and the winding member driving mechanism are driven by a common single driving source, the manufacturing cost is increased as compared with the case where separate driving sources are used for driving both mechanisms. Can be suppressed.

  The invention according to claim 3 is the used paper filter recovery device of the beverage extractor according to claim 2, wherein a gear portion is provided at one end of the winding member, and the winding member drive mechanism is A rotating body that is rotationally driven by a drive source, a drive gear that meshes with the gear portion and rotates as the rotating body rotates, and is provided between the rotating body and the driving gear. And a torque limiter for causing the rotating body to idle with respect to the driving gear when a torque of a predetermined magnitude or more acts on the rotating body from the driving gear when rotating. And

  According to this configuration, when the rotating body is rotationally driven by the drive source, the driving gear rotates as the rotating body rotates. In addition, since the drive gear meshes with a gear portion provided at one end of the winding member, the winding member is rotated by the rotation of the driving gear, whereby the used paper filter is turned into the winding member. Rolled up. As described above, in addition to the winding member driving mechanism that rotationally drives the winding member, the driving source also drives a paper feeding mechanism that feeds unused paper filters to the extractor body. In this case, when the feed amount of the unused paper filter by the paper feed mechanism and the winding amount of the used paper filter by the winding member driven by the winding member driving mechanism are approximately the same, the paper filter Can be smoothly wound and wound, and the used paper filter can be wound without loosening. However, as winding of the used paper filter proceeds and the number of paper filters wound around the winding member increases, the diameter gradually increases. For this reason, even if the rotation angle of the winding member that winds up the used paper filter is constant, the winding amount of the paper filter gradually increases. In this case, if the winding amount of the used paper filter due to rotation of the winding member is too large compared to the feeding amount of the unused paper filter by the paper feeding mechanism, excessive tension acts on the paper filter. There is a risk of breaking.

  Therefore, in the present invention, in the winding member driving mechanism, a predetermined torque limiter is provided between the rotating body that is rotationally driven by the driving source and the driving gear that meshes with the gear portion of the winding member, thereby providing the above-described description. The paper filter is prevented from breaking. That is, when the winding amount of the used paper filter is larger than the feeding amount of the unused paper filter, the tension of the paper filter increases, and thereby the winding member for winding the used paper filter. The torque acts from the paper filter in the direction opposite to the winding direction. This torque also acts on the drive gear meshing with this via the gear portion of the winding member. When the torque is greater than or equal to a predetermined magnitude and acts on the rotating body from the drive gear that rotates as the rotating body rotates, the torque limiter causes the rotating body to idle relative to the drive gear. To do. Thereby, even if the rotating body is rotated by the driving source, the driving gear does not rotate, so that the winding member does not rotate, and the used paper filter is not wound. As described above, the used paper filter can be wound up loosely while effectively preventing breakage due to excessive tension acting on the paper filter.

  According to a fourth aspect of the present invention, in the used paper filter recovery device for a beverage extractor according to any one of the first to third aspects, the tip of the paper filter is engaged with the peripheral surface of the winding member. A stop is provided.

  According to this configuration, the paper filter is wound around the rotating winding member in a state in which the front end portion is locked to the locking portion provided on the circumferential surface of the winding member. The paper filter can be stably wound up without spinning around the used paper filter wound up.

According to a fifth aspect of the present invention, in the used paper filter recovery device for a beverage extractor according to any one of the first to fourth aspects, the winding member has two windings that are detachable from each other at the center in the length direction. It consists of a piece.

  According to this configuration, when removing the used paper filter from the winding member, the two winding pieces are pulled in the opposite directions to separate each other, thereby removing the used paper filter from the winding member. It can be done very easily.

First, the filter block 27 is raised from this standby state, and the lower surface of the cylinder 21 is sealed while the paper filter P is pressed against the lower surface of the cylinder 21. Next, raw materials and hot water are supplied into the cylinder 21 from above, and coffee is extracted in the cylinder 21. Then, the extracted coffee is filtered by the paper filter P and carried out of the coffee extractor 1 through the filter block 27.

  Thereafter, as shown in FIG. 12B, the filter block 27 is lowered and the paper filter P is separated from the cylinder 21. In this case, as shown in the figure, the extracted soot G remains in the portion corresponding to the cylinder 21 of the paper filter P. Next, when the motor 61 is operated and the drive gear 63 rotates once, the paper feed drums 52 and 52 of the paper filter delivery device 4 rotate once in the clockwise direction in FIG. As a result, the paper filter P is pulled out from the paper holder 41 by a predetermined length while being sandwiched between the paper feed drums 52 and 52 and the paper sandwiching rollers 54 and 54, and is fed out toward the take-up reel 72. Further, in this case, by the operation of the motor 61, the take-up reel 72 is driven to rotate clockwise through the take-up reel drive mechanism 73. The paper filter P is taken up on the take-up reel 72.

  When the paper filter P is sent out as described above, the extraction residue G remaining on the paper filter P passes between the paper feed drum 52 and the paper clamping roller 54, as shown in FIG. 13 (a). In addition, by dropping by its own weight, it is accommodated in the extraction basket accommodating portion 85 of the waste container 71. Further, as shown in FIG. 13 (b), the extracted soot G that has not fallen by its own weight is scraped off by the scraper 83 when the paper filter P passes over the scraper 83. It falls as shown and is accommodated in the extraction basket accommodating portion 85. Therefore, most of the extracted soot G remaining on the paper filter P is accommodated in the extract soot container 85 of the waste container 71, while the used paper filter P in a state in which the extracted soot G is almost removed is used. The paper is taken up by the take-up reel 72 and accommodated in the used paper filter accommodating portion 86 of the waste container 71.

  Next, a manual setting procedure of the paper filter P in the coffee extractor 1 will be described with reference to FIGS. FIG. 14A shows a state before the roll part Pr of the paper filter P is loaded into the paper holder 41. From this state, first, the waste container 71 is pulled forward, removed from the coffee extractor 1, and the roll portion Pr of the paper filter P is loaded into the paper holder 41 from below as shown in FIG.

  Next, the paper holder 41 located at the use position is slightly lifted, and the locking portions 45, 45 are removed from the lock portions 25a, 25a on the extractor body 2 side. Thereby, the lock | rock of the paper holder 41 with respect to the extractor main body 2 is cancelled | released. Next, in this state, the paper holder 41 is slightly rotated forward with the support shaft 49b as a fulcrum, and the mounting screws 48, 48 of both arms 47, 47 are supported as fulcrums as shown in FIG. As shown in FIG. Thereafter, the front cover 23 of the cylinder holder 22 is opened, and the cylinder 21 is removed from the cylinder holder 22. Thereby, a relatively large space is secured above the filter block 27 in the cylinder holder 22.

  Next, while pulling out the paper filter P from the paper holder 41, as shown in FIG. 15A and FIG. 15B in sequence, the front end of the paper filter P is sent from the front of the cylinder holder 22 to above the filter block 27. Then, it passes through between the paper feed drum 52 and the paper sandwiching roller 54 at the rear thereof, and is hung below the extractor body 2.

  Next, after attaching the removed cylinder 21 to the cylinder holder 22, the paper holder 41 located at the retracted position is rotated upward, and the locking portions 45, 45 are connected to the lock portion 25a on the extractor body 2 side, 25a is engaged, and the paper holder 41 is locked in a use position. Thereafter, as shown in FIG. 16A, the front end portion of the paper filter P that hangs downward from the extractor main body 2 is pulled out to the front, and is engaged with both the engaging portions 94, 94 of the take-up reel 72. Then, the take-up reel 72 is rotated several times to slightly take up the paper filter P around the take-up reel 72. Then, as shown in FIG. 6B, the removed waste container 71 is attached to the outer case 6, and the take-up reel 72 is attached to the bearing groove 87 of the waste container 71, so that the take-up reel 72 The gear portion 92 is engaged with the reel drive gear 103. Thus, the setting of the paper filter P to the coffee extractor 1 is completed.

  As described above in detail, according to the present embodiment, the take-up reel 72 is rotatably supported by the waste container 71 provided in the lower portion of the coffee extractor 1, and the used reel 72 has been used. Since the paper filter P is wound up, the used paper filter P can be efficiently collected, unlike the conventional case where the paper filter P is simply sent out from above and tends to be bulky. For this reason, it is not necessary to unnecessarily increase the space for collecting the used paper filter P. Therefore, the overall height of the coffee extractor 1 including the space can be configured in a compact manner.

  In addition, by driving the paper feed mechanism 42 and the take-up reel drive mechanism 73 using a single motor 61 as a common drive source, the used paper filter P is removed while the paper filter P is being sent out from the paper holder 41. Since winding is performed, stable feeding and winding of the paper filter P can be ensured, and an increase in manufacturing cost can be suppressed as compared with the case where separate driving sources are used for driving both mechanisms 42 and 73. Can do.

  In the take-up reel drive mechanism 73, a predetermined torque limiter 105 is provided between the driven pulley 101 that is rotationally driven by the motor 61 and the reel drive gear 103 that meshes with the gear portion 92 of the take-up reel 72. Therefore, when the drive gear 63 rotates once by the operation of the motor 61, the diameter of the used paper filter P taken up by the take-up reel 72 is large. Even when the amount is larger than the delivery amount, the driven pulley 101 idles with respect to the reel drive gear 103, so that it can be used while effectively preventing breakage due to excessive tension acting on the paper filter P. The used paper filter P can be wound up without loosening.

  Further, since the diameter of the take-up reel 72 gradually decreases toward the center in the length direction, the extraction that cannot be completely removed by the scraper 83 between the used paper filters P that have been taken up. Even if the ridge G is interposed, it is possible to suppress an increase in the diameter near the center in the width direction. Thereby, it is not necessary to increase the space for collecting the used paper filter P, and handling of the paper filter P at the time of disposal can be facilitated.

  Further, since the take-up reel 72 is detachably attached to the waste container 71, the used paper filter P from the take-up reel 72 can be removed from the waste container 71 with the take-up reel 72 removed from the waste container 71. Removal and attachment of the paper filter P to the take-up reel 72 can be performed relatively easily. In addition, since the take-up reel 72 is composed of two reel pieces 90A and 90B, when removing the used paper filter P from the take-up reel 72, the two reel pieces 90A and 90B are placed in directions opposite to each other. The used paper filter P can be removed from the take-up reel 72 very easily by pulling and separating them.

  In addition, this invention can be implemented in various aspects, without being limited to the said embodiment described. For example, in the embodiment, the case where the present invention is applied to a coffee extractor has been described, but the present invention can also be applied to a beverage extractor that extracts tea-based beverages using tea leaves as a raw material. Further, the detailed configuration of the coffee extractor 1 shown in the embodiment is merely an example, and can be appropriately changed within the scope of the gist of the present invention.
