Description

[Technical Field]

[0001] The present invention relates to a corking device that automatically removes corks as a preparatory step before removing the contents (residual liquid) from barrels (mainly whiskey barrels) placed sideways on a conveyor for transportation. [Background technology]

[0002] When storing alcoholic beverages such as whiskey and wine, wooden barrels (cylindrical containers with a bulging outward midway along their height) are widely used as containers because they have a positive effect on the taste and aroma.

[0003] In the production of whiskey, wine, etc., a process called aging (barrel aging) is employed in which whiskey, wine, etc. are stored in barrels for a certain period of time in order to give them a deep flavor. Therefore, in whiskey, wine, etc. production plants, it is necessary to transport barrels from the aging warehouse and pour (extract) the alcohol (aged alcohol) from the inside of the barrel, or to pour (fill) alcohol (new alcohol) into the barrel for new aging. In addition, the barrel has a barrel hole (so-called dowel hole) drilled in the most bulging part in the center of the height direction, and the pouring and pouring of alcohol from and into the barrel must be carried out through this barrel hole.

[0004] Attempts have been made to automate the manufacturing process in order to facilitate the above-mentioned tasks of transporting barrels, pouring alcohol from the barrels, and pouring alcohol into the barrels. For example, Patent Document 1 proposes a liquid filling and withdrawing system for barrels, which includes a work unit for filling and withdrawing liquid from barrels, and a conveying device for automatically transporting the barrels between the work unit and racks stacked in multiple tiers to store the barrels in a three-dimensional manner. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-034408 Summary of the Invention [Problem to be solved by the invention]

[0006] According to the liquid filling and extraction system for kegs described in Patent Document 1 above, kegs are automatically transported from the rack where they are stored to the work area where the liquid is filled and extracted, eliminating the need for workers to go to the keg storage location and transport the kegs to the liquor pouring and injection area, making the entire process more efficient.

[0007] However, as mentioned above, the work of pouring alcohol from inside the barrel and the work of pouring alcohol into the barrel must be done through the barrel hole, so in the barrel liquid filling and extraction system of Patent Document 1, for each barrel that is transported, an operator must turn the barrel on its side as it is transported to the alcohol pouring and injection area, remove the barrel bung that is screwed into the barrel hole, and insert into the barrel hole a device for pouring alcohol from the inside or a device for injecting alcohol into the inside.The barrel liquid filling and extraction system of Patent Document 1 cannot necessarily be said to be efficient in operation. In addition, since liquor barrels (especially whiskey barrels) vary in size (height, diameter, etc.) (there is no standardized standard), it is difficult to automate the uncorking process.

[0008] The object of the present invention is to provide an automatic barrel uncorking device that eliminates the problems of conventional alcoholic beverage production systems such as the barrel liquid filling and extraction system of Patent Document 1, and that can facilitate the operations of pouring alcohol from inside a barrel and pouring alcohol into the barrel. [Means for solving the problem]

[0009] In order to solve the above-mentioned problems, the invention described in claim 1 is a keg uncorking device for removing keg plugs from kegs placed horizontally on a conveyor of a conveyor line, characterized in that it comprises a lifting and rotating means for lifting the keg above the conveyor and rotating it, a keg plug detection means for detecting the position of the keg plug, and an uncorking means having a drill at the tip for removing the keg plug. In this specification, the horizontal direction of the keg refers to the longitudinal direction of the barrel. The rotational direction of the keg refers to the direction perpendicular to the horizontal direction of the keg. Furthermore, the horizontal center of the keg refers to the plane (circle) formed by the trajectory of the keg plug (and the keg hole) when the keg is rotated, and the rotational center of the keg refers to the plane (vertical plane) including the rotation axis when the keg is rotated.

[0010] The invention described in claim 2 is characterized in that, in the invention described in claim 1, it is provided with a restraining means for holding the barrel so that it does not float up together with the drill when the barrel plug is removed with the drill.

[0011] The invention described in claim 3 is characterized in that, in the invention described in claim 1, it is provided with a centering means for detecting the lateral center and rotational center of the barrel when it is lifted above the conveyor by the lifting and rotating means and rotated.

[0012] The invention described in claim 4 is characterized in that, in the invention described in claim 1, the drill has a taper angle adjusted to 0 to 3°. The shape of the drill in the present invention is not particularly limited, but a screw-type drill in which a generally strip-shaped drill bit is spirally wound so as to taper from the base end to the tip along the axis is preferred. In this specification, the taper angle refers to the angle of the tip of a cone formed by imaginarily connecting the tips (outermost edges) of the drill bits spirally wound along the axis (i.e., the angle at the intersection of an imaginary line connecting the tips of the drill bits on one side and an imaginary line connecting the tips of the drill bits on the opposite side in a side view of the drill) (see FIG. 3).

[0013] The invention described in claim 5 is characterized in that, in the invention described in claim 1, the restraining means prevents the barrel from floating up by pressing the barrel in the opposite direction (downward) to the direction in which the drill pulls out the barrel plug (upward). [Effects of the Invention]

[0014] The keg uncorking device (hereinafter simply referred to as the uncorking device) described in claim 1 can use a drill to remove the keg plug, whose position has been detected by the keg plug detection means, from the keg while the lifting and rotating means lifts and rotates the keg above the conveyor. Therefore, the keg uncorking device described in claim 1 can automatically remove the keg plug from the keg without the need for an operator, making it possible to efficiently carry out kegging and uncorking operations in the manufacturing process of alcoholic beverages (whiskey, etc.).

[0015] The uncorking device described in claim 2 is equipped with a restraining means for holding the barrel so that it does not float up together with the drill when the barrel plug is removed with the drill, so that the barrel plug can be removed from the barrel smoothly and with high precision without causing the barrel to shift position during the uncorking operation.

[0016] The cork removal device described in claim 3 is equipped with a centering means for detecting the lateral center and rotational center of the barrel when it is lifted above the conveyor and rotating.Therefore, even if the barrels being transported are of different sizes, the barrel stopper detection means can accurately detect the position of the barrel stopper, so that the drill can be reliably thrust (pressed) into the barrel stopper with greater accuracy.

[0017] In the uncorking device described in claim 4, the drill angle is adjusted to 0 to 3°, allowing the drill to smoothly penetrate into the inside of the barrel stopper, thereby enabling the barrel stopper to be removed from the barrel with greater accuracy and reliability.

[0018] The uncorking device described in claim 5 has a restraining means that prevents the barrel from floating up by pressing the barrel in the opposite direction (downward) to the direction (upward) in which the drill pulls out the barrel plug, making it possible to remove the barrel plug from the barrel very smoothly and reliably with extremely high precision without causing the barrel to shift position during the uncorking operation.

[0020] <Conveyor device configuration> Hereinafter, an embodiment of an uncorking device and a transport device equipped with the uncorking device according to the present invention will be described in detail with reference to the drawings. If a barrel for whiskey or other alcoholic beverages is excessively dry, gaps will form between the wood grain, making it prone to leaks when the whiskey or other alcoholic beverage is filled. Therefore, the barrel is corked and stored in a state where the wood expands by adding water or the like to eliminate gaps. Therefore, when barreling whiskey or other alcoholic beverages, the barrel must be uncorked and the water or the like must be drained before the whiskey can be filled and the barrel transported to a storage facility or the like for aging.

[0021] FIG. 1 shows an example of a conveying device (for conveying casks of liquor such as whiskey) equipped with a cork removal device. Casks B, conveyed by conveying device C, are cylindrical, assembled from wood with a central bulge outward. A barrel hole (also called a dowel hole) H, used for pouring or pouring contents, is drilled in the side (also called the periphery or body) approximately in the center of the height direction. A wooden or plastic barrel bung (also called a dowel stopper or bung) T is screwed into barrel hole H, sealing the interior of barrel B. Conveying device C transports such casks (casks) B, B, etc. in a horizontal position, removes barrel bung T at a predetermined location, and then transports them to a different location to pour liquid (young liquor) into the casks (or pour liquid (aged liquor) from the casks).

[0022] Upstream of the conveying device C, there is installed a corking device M for removing barrel corks T from barrels B, B, etc., which are laid on a chain conveyor-type conveying line L (laying so that their height is perpendicular to the conveying direction). Downstream of the corking device M, there is installed an injection / pour-out device 1 for injecting liquid (young sake) into the barrels and pouring liquid (aged sake) out of the barrels. The injection / pour-out device 1 is capable of injecting liquid (young sake, etc.) from a filling liquid tank (not shown) into the barrels B and pouring liquid (aged sake, etc.) from the barrels B into a recovery liquid tank (not shown) by operating a four-axis articulated robot arm R under the control of a control device (not shown).

[0023] Further, on the conveying line L, receiving claw members 31, 31... for fixing the laid barrels B, B... are provided at regular intervals along the longitudinal direction at predetermined intervals in the front, rear, left and right directions so that there are four of them for each barrel B. Note that each set of two receiving claw members 31, 31 on the left and right sides is inclined downward from the outside to the inside so that the upper surface abuts the peripheral surface of the barrel B. Furthermore, a positioning member 32 is provided on the front surface of each receiving claw member 31, 31 installed on the downstream side (downstream side) of a set of receiving claw members 31, 31...

[0024] Furthermore, the area where the uncorking device M on the conveying line L is installed is divided into a detection station S1, which detects the position of the barrel bung T of the barrel B and aligns (adjusts) the barrel B by rotating it so that the barrel bung T is facing straight up, and an uncorking station S2, which removes the barrel bung T from the barrel B after alignment.

[0025] <Configuration of the uncorking device> As shown in Figure 1, the uncorking device M has an uncorking preparation device M1 on the upstream side for fixing a barrel B with the barrel hole H facing directly upward to identify the position of the barrel plug T, and a barrel plug removal device M2 for removing the barrel plug T from the barrel B fixed by the uncorking preparation device M1. Figure 2 shows the uncorking preparation device M1, which is equipped with a lifting and rotating device (lifting and rotating means) 33, which is an elevating device for lifting and rotating the barrel B placed on the conveyor line L, a centering means 34 for detecting the center of the barrel B in the lateral direction (the width direction of the conveyor line L) and the center of the barrel B in the vertical direction (the height direction of the barrel B when lying down) in a state where the barrel B has been lifted and rotated by the lifting and rotating device 33, and a barrel plug detection means 35 for detecting the barrel plug T.

[0026] The lifting and rotating device 33 is installed so as to be positioned approximately directly below the barrel B (barrel B lying down) being transported on the conveyor line L, and is composed of a fixed base 46, rails 47 installed on the upper surface of the base 46 along the longitudinal direction of the conveyor line L, and a movable body 48 installed on the rails 47 so as to be movable along the longitudinal direction of the conveyor line L. The movable body 48 also includes a lift section 44 that rises and falls to lift the barrel B, a cylinder 45 that is a drive device for raising and lowering the lift section 44, and rotating bodies 53, 53, etc. that are rotatably pivotally mounted on the lift section 44 in a two-row, two-column configuration. Meanwhile, the barrel stopper detection means 35 uses a camera with image processing capabilities to capture an image of the lateral center of the barrel B detected by the centering means 34, and by identifying the difference in color between the barrel stopper T and the barrel B itself in the image, it is able to distinguish between the barrel stopper T and the barrel B itself and detect (locate) the barrel stopper T.

[0027] The lifting and rotating device 33 is also equipped with a positioning means 51 for accurately positioning the moving body 48 with respect to a pair of front and rear receiving claw members 31, 31 installed on a chain conveyor-type transfer line L, and a position correction unit U consisting of a cylinder 49 for moving the moving body 48 back and forth with respect to the transfer line L. The positioning means 51 is installed on the outside of a rotating body 53 on the front side of the lift section 44, and has a positioning protrusion 52 at its upper end that is movable in the vertical direction by an elastic member (not shown). Meanwhile, the cylinder 49 is capable of sliding the moving body 48 back and forth along a rail 47 installed on a base 46.

[0028] On the other hand, Figure 3 shows a barrel plug removal device M2, which includes a cork removal means 37 having a drill 36 at the tip of a vertically arranged support shaft 39 for piercing a barrel plug T, a drive device (motor) 41 for rotating the support shaft 39 about the vertical axis, a cylinder 40 for moving the support shaft 39 up and down, and a holding means 38 for holding the barrel B so that the drill 36 does not float up together with the barrel B when the cork is removed. Figure 4 also shows the drill 36, which is a screw-type drill with a generally strip-shaped drill bit wound spirally so that it tapers from the base end to the tip along its axis, with the taper angle adjusted to a predetermined angle (approximately 2.5°). On the other hand, the holding means 38 includes a holding body 42 with a bifurcated lower side for holding the left and right sides of the barrel plug T (the top and bottom of the barrel B) when the cork is removed, and a cylinder 43 for applying downward pressure to the holding body 42.

[0029] <Operation details of barrel transport device> [Position correction using the position correction unit] In the conveying device C, as shown in Figure 1, a barrel B is conveyed lying on a chain conveyor-type conveying line L (with its height perpendicular to the flow direction) and secured by a set of receiving hooks 31, 31.... Once the barrel B is conveyed to the detection station S1 in the area where the uncorking device M is installed, the conveying line L is temporarily stopped to prepare for uncorking. The lying barrel B is then placed on the lifting and rotating device 33 of the uncorking preparation device M1 (onto the four rotating bodies 53, 53... of the lift section 44) and raised above the conveying line L.

[0030] 5 and 6 show how the lifting and rotating device 33 (lift unit 44) lifts a barrel B. When the lifting and rotating device 33 lifts a barrel B, a positional correction is performed to align the center position A of the pair of front and rear receiving claw members 31, 31 installed on the conveyor line L with the center position A' of the rotating bodies 53, 53 of the lifting and rotating device 33 so that the barrel B can be lifted in a stable state. Note that such a positional correction is necessary because, due to elongation of the chains that make up the conveyor line L (elongation due to wear at the joints between the chains, etc.), the center position A of the pair of front and rear receiving claw members 31, 31 and the center position A' of the rotating bodies 53, 53 of the lifting and rotating device 33 will shift (a shift G will occur) (the state shown in FIG. 5).

[0031] In position correction by the position correction unit U, first, the moving body 48 is pushed forward by the cylinder 49 (sliding forward along rails 47 installed on the base 46) so that the positioning protrusion 52 of the positioning means 51 of the lifting and rotating device 33 is positioned downstream of the installation position of the positioning member 32 of the downstream receiving claw member 31 of the pair of front and rear receiving claw members 31, 31. Then, when the moving body 48 is pushed forward in this manner, the positioning protrusion 52 of the positioning means 51 protrudes upward and abuts against the positioning member 32 installed in front of the downstream receiving claw member 31, as shown in FIG.

[0032] When the positioning protrusion 52 protrudes and abuts against the positioning member 32 in this way, the cylinder 49 stops operating, thereby stopping the moving body 48. The lifting and rotating device 33 is configured so that, at the front-to-rear position where the protruding positioning protrusion 52 abuts against the positioning member 32 of the downstream receiving claw member 31, the center position A' of the rotating bodies 53, 53 coincides with the center position A of the pair of front and rear receiving claw members 31, 31. Therefore, when the protruding positioning protrusion 52 abuts against the positioning member 32 of the downstream receiving claw member 31, the position correction is completed.

[0033] Once the position correction is completed as described above, the lift section 44 of the lifting and rotating device 33 is raised by the cylinder 45 with the lying barrel B placed on the four rotating bodies 53, 53... (i.e., the barrel B is lifted). Then, as shown in Figure 7, the rotating bodies 53, 53... are driven by a drive device (not shown) to rotate the barrel B, while the centering means 34 uses sensing technology and image processing technology to position the center of the barrel B in the horizontal direction and the rotational direction (i.e., centering). While the centering means 34 is positioning the center of the barrel B in the horizontal direction and the rotational direction in this way, the barrel stopper detection means 35 (a camera with image processing function) detects the position of the barrel stopper T, and the rotating bodies 53, 53... are driven via a control device to position the barrel stopper T directly above.

[0034] As described above, after the barrel bung T is positioned directly above, the cylinder 45 of the lifting and rotating device 33 is operated to lower the lift section 44, and the barrel B is placed on the conveying line L so that it is fixed by the set of receiving claw members 31, 31.... Note that, as described above, the moving body 48 of the lifting and rotating device 33 is accurately positioned with respect to the set of receiving claw members 31, 31... of the conveying line L, so that the barrel B is placed on the conveying line L while maintaining the barrel bung T positioned directly above. Also, as described above, once the barrel B is placed on the conveying line L, the moving body 48 is pulled backward by the cylinder 49 (it slides backward along the rail 47 installed on the base 46) in preparation for detection of the next barrel B to be conveyed.

[0035] [Uncorking using a bottle uncorking device] As described above, after the barrel B is placed on the conveyor line L with the barrel plug T positioned directly above it, the conveyor line L is moved to move the barrel B to the uncorking station S2, as shown in Figure 8. Then, when the barrel B arrives at the uncorking station S2, the support shaft 39 of the uncorking means 37 of the barrel plug removal device M2 is lowered by the cylinder 40, so that the drill 36 at the tip approaches the barrel plug T. Thereafter, the drill 36 at the tip is rotated by the drive device 41 and screwed into the barrel plug T.

[0036] After the drill 36 has been fully screwed into the barrel stopper T (piercing the barrel stopper T), the support shaft 39 of the uncorking means 37 is raised by the cylinder 40, thereby pulling out the barrel stopper T. If the barrel stopper T is in close contact with the barrel B when the barrel stopper T is being pulled out, there is a possibility that the barrel B will be lifted up along with the support shaft 39. To prevent this from happening, when the uncorking means 37 is uncorking the barrel, the holding means 38 uses the cylinder 43 to press down the holding bodies 42, 42, thereby holding down the periphery (left and right) of the barrel stopper T into which the drill 36 has been inserted, thereby preventing the barrel B from being lifted up. After the uncorking as described above, the conveying line L is operated (moved) again to transport the barrel B to the filling / pour-out station S3, in order to pour the liquid (young liquor) into the barrel B or pour the liquid (aged liquor) from the barrel B using the filling / pour-out device 1.

[0037] <Effects of the uncorking device> As described above, the uncorking device M comprises a lifting and rotating device (lifting and rotating means) 33 for rotating the barrel B while lifting it above the conveyor (chain conveyor-type transfer line L), a barrel plug detection means 35 for detecting the position of the barrel plug T, and an uncorking means 37 equipped with a drill 36 at the tip for removing the barrel plug T. Therefore, the uncorking device M can automatically remove the barrel plug T from the barrel B without requiring manual work by an operator, making it possible to efficiently carry out kegging and uncorking operations in the manufacturing process of whiskey, etc.

[0038] Furthermore, the uncorking device M is provided with a restraining means 38 for holding the barrel B so that the barrel B does not float up together with the drill 36 when the barrel plug T is removed with the drill 36, so that the barrel plug T can be smoothly and accurately removed from the barrel B without causing displacement of the barrel B during the uncorking operation.

[0039] Furthermore, the uncorking device M is equipped with a centering means 34 that detects the lateral center and rotational center of the barrel B when it is lifted above the conveyor and rotated by the lifting and rotating device (lifting and rotating means) 33.Therefore, even if the sizes of the barrels B, B... being transported vary, the position of the barrel stopper T can be detected very accurately by the barrel stopper detection means 35, so that the drill 36 can be reliably pierced (pressed against) the barrel stopper T with greater precision.

[0040] In addition, the uncorking device M has the drill 36 with its aperture angle adjusted to a predetermined angle (approximately 2.5°), allowing the drill 36 to smoothly penetrate into the interior of the barrel stopper T, thereby enabling the barrel stopper T to be removed from the barrel B with greater precision and reliability.

[0041] Furthermore, the uncorking device M has a retaining means 38 that presses the barrel B in the opposite direction (downward) to the direction (upward) in which the drill 36 pulls out the barrel plug T, thereby preventing the barrel B from floating up, making it possible to remove the barrel plug smoothly and reliably with extremely high precision without causing the barrel to shift position during the uncorking operation. Therefore, the uncorking device M makes it possible to more smoothly pour the liquid (young liquor) into the barrel B and automatically pour the liquid (aged liquor) from the barrel B using the subsequent pouring / dispensing device 1, making the kegging and uncorking operations of whiskey and the like extremely efficient.

[0042] <Example of modification of barrel uncorking device> The keg uncorking device according to the present invention is not limited to the aspects of the above-described embodiments, and the configurations of the lifting and rotating means, centering means, keg stopper detection means, drill, uncorking means, and restraining means can be appropriately changed as needed within the scope of the present invention. For example, the restraining means is not limited to the one that restrains the left and right sides (top and bottom of the keg) of the keg stopper of a keg placed sideways on the conveyor, as in the above-described embodiments, but can also be changed to one that restrains the front and back of the keg stopper (left and right of the keg stopper on the keg), one that restrains the front and back and left and right of the keg stopper, or one that restrains the periphery of the keg stopper in a circular manner.

[0043] Furthermore, the drill of the uncorking means is not limited to the screw type in which a roughly strip-shaped drill blade is wound spirally so as to taper from the base end to the tip along the axis, as in the above embodiment, but may be of a different type, such as one in which a tapered wire is wound spirally. However, when the drill is a screw-type drill with a generally strip-shaped drill bit wound in a spiral shape so that it tapers from the base end to the tip along the axis, and the taper angle is adjusted to 0 to 3°, there is an advantage in that the uncork function is improved. Table 1 shows the results of the inventors' investigation into the difference in uncork function when the taper angle of the screw-type drill is changed (the results of visually evaluating the screwing ability and penetration ability when each drill is screwed into the same barrel stopper with the same rotational force on a three-point scale). Table 1 shows that the uncork function is improved when the taper angle is adjusted to 0 to 3°.

[0044] [Table 1]

[0045] On the other hand, the conveying device equipped with the uncorking device is not limited to one that performs the preparatory work for uncorking, the uncorking operation, and the pouring / injecting of the contents at separate locations (stations), but can also be changed to one that performs any of the preparatory work for uncorking, the uncorking operation, and the pouring / injecting of the contents at the same location, or one that performs all of the preparatory work for uncorking, the uncorking operation, and the pouring / injecting of the contents at the same location. [Industrial Applicability]

[0046] The keg uncorking device of the present invention has the excellent effects as described above, and can therefore be suitably used as a device for constructing an automatic conveying line for whiskey barrels and the like. [Explanation of symbols]
