Description

  The present invention relates to a water removal device for a beverage container that removes water droplets attached to the beverage container.

  Beverage supply devices that can be installed in various places such as offices, hospitals, and general homes are known. As an example of the beverage supply device, a bottle (beverage container) pre-filled with water (product water) is attached to the main body of the beverage supply device, and the bottle water is supplied to the device based on the operation of the water supply cock by the user. Supply from the pipe to the outside. This type of beverage supply apparatus is configured such that a beverage container such as a gallon bottle is detachable from the apparatus main body.

  Beverage containers such as gallon bottles are returnable. That is, the bottle is collected after use by the customer, washed, refilled with the beverage, and delivered to the customer again. In a factory that performs these steps, since water drops flow onto the conveyor with water droplets attached to the bottles, it is necessary to remove the water droplets. If the water removal process is performed manually such as wiping, it is difficult to improve productivity, so automation is required.

  As one means for realizing the productivity improvement in the water removal process, for example, a water removal apparatus that blows water droplets with a strong wind using a blower or a compressor can be considered. However, in this apparatus, power consumption increases in order to remove water droplets in a short time. Furthermore, since water drops are scattered around, the sanitary environment becomes a problem.

  As another means for improving the productivity of the water removal process, water removal is performed by providing a tunnel in the transport path for transporting the beverage container, keeping the inside of the tunnel at a high temperature, and evaporating the water droplets by heat when the beverage container passes. A device is conceivable. However, this device requires a long tunnel for sufficient drying, while power consumption increases for a short tunnel, so it is difficult to achieve both space saving and low power consumption. .

  As a means other than the above for realizing the productivity improvement of the water removal step, a water removal device for sucking water droplets can be considered. For example, in Patent Document 1, a sponge is disposed along the conveyance path, an endless belt is provided to rotate the container while the container is pressed against the sponge, and water droplets attached to the container are removed by absorbing the sponge under reduced pressure. An apparatus is disclosed. Patent Document 2 discloses a water removal device that causes a contact member to contact a linear object and sucks water droplets attached to the linear object through the contact member with a negative pressure.

  The suction type water removal device is preferable in that the power consumption can be reduced by the characteristics of the motor as compared with the blow-off method and the evaporation method. However, the dewatering device of Patent Document 1 is effective for a light container, but a heavy container such as a gallon bottle is difficult to rotate freely because it is difficult to rotate the container itself. Can not do it. Moreover, in the water removal apparatus of the above-mentioned Patent Document 2, since the target for removing water droplets is limited to a linear object having no irregularities, it cannot be applied to a undulating beverage container.

  A cylindrical beverage container such as a bottle generally has a cylindrical shape or a polygonal cylindrical shape, and in order to apply a suction-type water removal device, a suction nozzle is provided along the surface of the undulating beverage container. Must be moved. In order to realize the complicated movement of the suction nozzle along the surface of the beverage container, various sensors for detecting the position of the nozzle and the beverage container, actuators such as a motor for moving the nozzle, and detection signals of the sensors are used. Although a water removal apparatus including a control unit that controls the driving of the actuator can be considered based on this, the system becomes complicated and the cost increases.

  The present invention has been made paying attention to such a problem, and its purpose is to realize the operation of the suction nozzle along the surface of the beverage container with a simple configuration, a good sanitary environment and power saving. It is providing the water removal apparatus for drink containers which implement | achieved.

As the beverage container advances, the suction nozzle moves along the at least side surface of the beverage container from the downstream side to the upstream side by utilizing the operation of pushing the suction nozzle away from the initial position to the non-interference position. It is characterized by comprising.

  According to this configuration, the operation of the suction nozzle along the beverage container can be realized with a simple configuration without using an actuator such as a motor, a sensor, or a control unit. Since the suction-type water removal device usually requires less energy for the motor than the exhaust-type water removal device, it is possible to provide a water removal device for a beverage container that realizes a good sanitary environment and power saving. It becomes possible.

  In order for the suction nozzle to follow the surface shape of the beverage container, the suction nozzle can be changed in posture by swinging to one of a plurality of postures including a backward posture facing the upstream side and a forward posture facing the downstream side.

A pair of abutting portions against the side surface of the beverage container by the urging force of the position returning urging portion and the posture returning urging portion so as to face the surface of the beverage container. It is preferable that a nozzle posture defining portion for defining the posture of the suction nozzle is provided.

  In order to realize a configuration for supporting the suction nozzle in a movable manner with a simple configuration, it is desirable that the nozzle support portion supports the suction nozzle in a movable manner by a slide operation.

In this case, in order for the suction nozzle to appropriately follow the upstream side surface, it is desirable that the suction nozzle at the initial position is set upstream of the rotation base point.

  In order to improve the durability of the urging portion, at least a part of the urging portion is a weight-type urging portion having a weight and a conversion mechanism that converts gravity acting on the weight into an urging force. It is effective.

  In order to eliminate the problem that may occur by moving the suction nozzle along the side surface of the beverage container, the beverage container is rotated by contact with the suction nozzle when the beverage container has a polygonal cylindrical shape. It is mentioned that the guide which prevents this is provided in the width direction both sides of the conveyance path.

In the case of the first suction unit 3, the initial position p <b> 1 is set to the downstream end 12 of the beverage container 1 or a position that is slightly on the one side WD <b> 1 in the width direction from the downstream end 12, as shown in FIG. 3. The nozzle support portion 31 supports the suction nozzle 30 so as to be movable by a sliding operation. As shown in FIGS. 3 and 4, the nozzle support portion 31 includes a rod-like slide arm 32 extending in a slide direction orthogonal to the traveling direction GD1, and a slide base portion that supports the slide arm 32 so as to be movable along the slide direction. 33. The suction nozzle 30 is attached to the tip of the slide arm 32 so as to be rotatable about the vertical axis CL1, so that the posture can be changed by swinging to any of a plurality of postures including the backward posture s1 and the forward posture s3. Yes. The movable range of the slide arm 32 is defined by the stopper 34 so that the moving range of the suction nozzle 30 is between the initial position p1 and the non-interference position p2.

  As shown in FIGS. 3 and 4, the slide base 33 and the slide arm 32 are connected by an elastic member 35a such as a coil spring that accumulates an elastic repulsive force when moving from the initial position p1 to the non-interference position p2. ing.

The ribbon winder 36b is provided with an elastic member (not shown) such as a coil spring that accumulates an elastic repulsion when the suction nozzle 30 changes its posture from the backward posture s1 to the forward posture s3. Thus, the posture returning urging portion 36 that generates the urging force for returning the suction nozzle 30 to the backward posture s1 is configured.

  As shown in FIG. 3, a pair of contact portions 37 a and 37 b for contacting the beverage container 1 are disposed on the downstream side GD <b> 1 and the upstream side GD <b> 2 of the suction nozzle 30. When the pair of contact portions 37a and 37b both contact the side surface 10 of the beverage container 1, both the contact portions 37a and 37b are arranged so that the posture of the suction nozzle 30 faces the surface of the beverage container 1. 30 is attached. In the present embodiment, the positional relationship between the abutment portions 37a and 37b and the suction nozzle 30 is set so that the suction ports 30b and 30c of the suction nozzle 30 abut against the surface of the beverage container 1 at a right angle. If comprised in this way, a pair of contact part 37a, 37b will contact | abut to the side surface of the drink container 1 by the urging | biasing force of the said position return urging part 35 and the attitude | position return urging part 36, and the surface of the drink container 1 A nozzle posture defining unit 37 that defines the posture of the suction nozzle 30 in a posture facing the direction is realized. As shown in FIG. 4, the contact portions 37 a and 37 b of the present embodiment are a pair of rollers that are respectively arranged up and down. The abutting portions 37a and 37b are arranged on both the upstream side GD2 and the downstream side GD1 of the suction nozzle 30 to form a pair, so that a total of four rollers are arranged.

  Next, the second suction unit 4 will be described. In the case of the second suction unit 4, the initial position p <b> 1 is set to the downstream end 12 of the beverage container 1 or a position that is slightly on the other side WD <b> 2 in the width direction from the downstream end 12, as shown in FIG. 5. The nozzle support part 41 supports the suction nozzle 40 so as to be movable by a rotation operation around a predetermined rotation base point. As shown in FIGS. 5 and 6, the nozzle support portion 41 includes a base portion 43 installed on the other side WD <b> 2 in the width direction of the conveyance path 20 and a pair of one end rotatably attached to the base portion 43 and parallel to each other. The rotating arms 42 and 42 are connected to each other, and the connecting arms 44 are connected to the rotating arms 42 and 42 and the suction nozzle 40 is attached to the tip thereof. A link mechanism that rotates around the base point is configured. The suction nozzle 40 is configured to be able to change its posture by swinging to one of a plurality of postures including the backward posture s1 or the forward posture s3 by being attached to the tip of the connecting arm 44 so as to be rotatable about the vertical axis CL2. Yes. The rotatable region of the link mechanism is defined by the stopper 4a so that the moving range of the suction nozzle 40 is between the initial position p1 and the non-interference position p2.

  As shown in FIGS. 5 and 6, the base portion 43 and the rotating arm 42 are connected by an elastic member 45 a such as a coil spring that accumulates an elastic repulsive force when moving from the initial position p <b> 1 to the non-interference position p <b> 2. Yes. As a result, a position returning urging portion 45 that generates an urging force for returning the suction nozzle 40 to the initial position p1 is configured. The suction nozzle 40 at the initial position p1 is set on the downstream side GD1 from the rotation base point. Similar to the first suction unit 3, a ribbon take-up portion 46 b that feeds or winds the belt-like ribbon 46 a is provided at the distal end portion of the connecting arm 44, and an urging force that returns the suction nozzle 40 to the backward posture s 1. The posture returning urging portion 46 that generates the above is configured. Similarly to the first suction unit 3, a pair of contact portions 47 a and 47 b are arranged on the downstream side GD 1 and the upstream side GD 2 of the suction nozzle 40, so that the posture facing the surface of the beverage container 1 is achieved. A nozzle posture defining section 47 that defines the posture of the suction nozzle 40 is realized.

As shown in FIG. 1, the first suction unit 3 and the second suction unit 4 are displaced along the traveling direction GD1 so as not to overlap each other when viewed from the direction orthogonal to the traveling direction GD1 (width direction WD). Are arranged. In the present embodiment, the first suction unit 3 is disposed on the upstream side GD2 with respect to the second suction unit 4, but the first suction unit 3 is disposed on the downstream side GD1 with respect to the second suction unit 4. May be. Further, when there is a sufficient installation space around the width direction WD of the conveyance path 20, the suction units 3 and 4 are arranged so as to overlap each other when viewed from the direction (width direction WD) perpendicular to the traveling direction GD1. Also good.

  The operation of the beverage container dewatering device having the above-described configuration will be described. As shown in FIG. 1, in the initial state, the suction nozzles 30 and 40 of the first and second suction units 3 and 4 stand by in a backward posture s1 at their initial positions p1.

  The width direction dimension which occupies the conveyance path 20 changes with the drink containers 1 which have a hexagonal cylindrical part. For example, although not illustrated, when the corners of the side surface 10 face the one side WD1 in the width direction and the other side WD2 in the width direction, the width direction dimension becomes maximum. On the other hand, as shown in FIG. 1, when the flat surfaces of the side surfaces 10 face the width direction one side WD1 and the width direction other side WD2 of the transport path, the dimension in the width direction WD is minimized. In the present embodiment, the beverage container 1 is transported in a posture in which the dimension in the width direction WD is reduced. At this time, the downstream end of the side surface 10 of the beverage container 1 is a corner that faces the traveling direction.

  When the beverage container 1 travels through the conveyance path 20, the suction nozzle 30 of the first suction unit 3 comes into contact with the beverage container 1 as shown in FIG. 3. At this time, the contact portions 37a and 37b (four rollers) that make a pair come into contact with the front side surface 13 of the beverage container 1, and the backward posture s1 in which the suction nozzle 30 faces the front side surface 13 of the beverage container 1 is maintained. The front side surface 13 means a flat surface on the downstream side of the side surface 10 of the beverage container 1. As shown in FIGS. 3 and 7, as the beverage container 1 advances, the slide arm 32 retracts against the conveying force of the conveying device 2 (that is, the propelling force of the beverage container 1), and the suction nozzle 30 moves to the initial position. The suction nozzle 30 is pushed away from p1 to the non-interference position p2, and moves along the at least side surface 10 of the beverage container 1 from the downstream GD1 to the upstream GD2.

  As shown in FIG. 7, when the suction nozzle 30 reaches the inner side surface 14 from the front side surface 13, the contact portion 37b on the upstream side GD2 is separated from the front side surface 13, and the suction nozzle 30 is centered on the swing axis CL1. By rotating, both contact portions 37a, 37b are transferred to the inner side surface 14, and the posture is changed to an inward posture s2 in which the suction nozzle 30 faces the inner side surface 14 of the beverage container 1. The middle side surface 14 means a flat surface outside the width direction WD of the side surface 10 of the beverage container 1.

Further, as shown in FIG. 8, when the suction nozzle 30 reaches the rear side surface 15 from the middle side surface 14, the contact portion 37 b on the upstream side GD <b> 2 is separated from the middle side surface 14, and the position return biasing portion 35 is attached. the force, each abutment portion 37a rotates the suction nozzle 30 about the swing axis CL1, 37b is Noriutsuri the rear side 15, attitude suction nozzle 30 is in the forward-facing position s3 facing side 15 after the beverage container 1 change is made. The rear side surface 15 means a flat surface on the upstream side GD2 in the side surface 10 of the beverage container 1. Then, the suction nozzle 30 moves along the rear side surface 15 by the biasing force of the position return biasing portion 35. Thus, water droplets adhering to the half surface of the width direction one side WD1 of the side surface 10 and the shoulder surface 11 of the beverage container 1 are appropriately sucked by the suction nozzle 30. When the contact between the suction nozzle 30 and the beverage container 1 is released, the suction nozzle 30 returns to the initial position p1 and the backward posture s1 by the biasing force of the biasing portions 35 and 36.

  Furthermore, when the beverage container 1 advances, the suction nozzle 40 of the second suction unit 4 comes into contact with the beverage container 1 as shown in FIG. At this time, the suction nozzle 40 is maintained in the backward posture s1 by the contact portions 47a and 47b in the same manner as described above. As the beverage container 1 advances, the link mechanism retracts against the propulsive force of the beverage container 1, the suction nozzle 40 is pushed away from the initial position p1 to the non-interference position p2, and the beverage container moves from the downstream GD1 to the upstream GD2. The suction nozzle 40 moves along at least the side surface 10 of 1. As the beverage container 1 advances, the suction nozzle 40 sequentially moves to the front side surface 13, the middle side surface 14, and the rear side surface 15 as shown in FIGS. Thus, water droplets adhering to the remaining half surface of the other side WD2 in the width direction of the side surface 10 and the shoulder surface 11 of the beverage container 1 are appropriately sucked by the suction nozzle 40. Note that when the contact between the suction nozzle 40 and the beverage container 1 is released, the suction nozzle 40 returns to the initial position p1 and the backward posture s1 by the biasing force of the biasing portions 45 and 46.

  Here, for example, when removing water droplets adhering to the beverage container 1 with a line of about 1 m in the blowing method of blowing air, the power required for the blow generator is about 12 kW, but in this embodiment, about 1 m. When removing the water droplets adhering to the beverage container 1 in the same line, the power required for the suction device 6 was about 6.3 kW. Thus, if this invention is used, it will become possible to reduce power consumption effectively.

As described above, the water removal device for a beverage container according to the present embodiment is a device that removes water droplets attached to the beverage container 1 conveyed along the conveyance path 20 extending in the predetermined traveling direction GD1,
A suction nozzle 30 (40) for sucking water droplets adhering to the beverage container 1;
It can be moved to either the initial position p1 that interferes in the traveling direction GD1 with the beverage container 1 traveling in the transport path 20 with the side surface 10 facing the traveling direction GD1, or the non-interfering position p2 that does not interfere with the beverage container 1 in the traveling direction GD1. A nozzle support portion 31 (41) for supporting the suction nozzle 30 (40);
A position return urging portion 35 (45) for generating a urging force for returning the suction nozzle 30 (40) to the initial position p1,
Using the operation of pushing the suction nozzle 30 (40) away from the initial position p1 to the non-interference position p2 as the beverage container 1 advances, suction is performed along at least the side surface 10 of the beverage container 1 from the downstream GD1 to the upstream GD2. The nozzle 30 (40) is configured to move.

  According to this configuration, the operation of the suction nozzle 30 (40) along the beverage container 1 can be realized with a simple configuration without using an actuator such as a motor, a sensor, or a control unit. Since the suction-type water removal device usually requires less energy for the motor than the exhaust-type water removal device, it is possible to provide a water removal device for a beverage container that realizes a good sanitary environment and power saving. It becomes possible.

Furthermore, in this embodiment, the suction nozzle 30 (40) is nozzle-supported so that the posture can be changed by swinging to any one of a plurality of postures including a backward posture s1 facing the upstream GD2 and a forward posture s3 facing the downstream GD1. Part 31 (41),
A posture return biasing portion 36 (46) for generating a biasing force for returning the suction nozzle 30 (40) to the backward posture s1 is provided.
It has a pair of contact portions 37a, 37b (47a, 47b) disposed on the downstream side GD1 and the upstream side GD2 of the suction nozzle 30 (40), and includes a position return biasing portion 35 (45) and a posture return attachment. Nozzle posture regulation that regulates the posture of the suction nozzle 30 (40) so that the pair of abutting portions are brought into contact with the side surface of the beverage container by the biasing force of the biasing portion 36 (46) and face the surface of the beverage container. A portion 37 (47) is provided.

  If comprised in this way, since the attitude | position of the suction nozzle 30 (40) is prescribed | regulated in the attitude | position which faces the surface of the beverage container 1, the rear side surface 15 in the upstream GD2 can be sucked with a simple configuration, and the suction nozzle 30 ( 40) can be made to follow the surface shape of the beverage container 1.

  Furthermore, in this embodiment, since the nozzle support part 31 supports the suction nozzle 30 so that a movement is possible by slide operation, the structure which supports the suction nozzle 30 so that a movement is possible is realizable with a simple structure.

  Furthermore, in the present embodiment, the nozzle support portion 41 supports the suction nozzle 40 so as to be movable by a rotation operation around a predetermined rotation base point. Therefore, the arrangement space required around the transport path 20 is slid. It becomes possible to reduce compared with the case.

  As mentioned above, although embodiment of this invention was described based on drawing, a specific structure is not limited to these embodiment. The scope of the present invention is shown not only by the above description of the embodiments but also by the scope of claims for patent, and further includes all modifications within the meaning and scope equivalent to the scope of claims for patent.

<Other embodiments>
For example, one of the paired suction units 3 and 4 is a slide operation type and the other is a rotation operation type, but both may be a slide operation type, or both may be a rotation operation type.

  The position return urging portions 35 and 45 and the posture return urging portions 36 and 46 use the elastic force of the elastic member as an urging force. At least a part of these urging portions is used as a weight and a weight. You may comprise the weight type urging | biasing part which has the conversion mechanism which converts the working gravity into the urging | biasing force. For example, one end of the wire is connected to the suction nozzle, a weight is attached to the other end, and a pulley that converts gravity acting on the weight into a biasing force is provided. The urging portion by the elastic member has a life of the elastic member, but if the weight type urging portion is employed, the weight is not used and the durability can be improved.

  Further, in the suction unit 4 that is a rotary operation type, the suction nozzle 40 at the initial position p1 is set downstream of the rotation base point. In this case, when the suction nozzle 40 moves from the inner side surface 14 to the rear side surface 15, the suction nozzle 40 tries to move to the upstream side GD <b> 2 that moves away from the rear side surface 15 by the rotation trajectory. May be difficult to contact with the rear side surface 15. Therefore, it is preferable that the suction nozzle at the initial position is set upstream of the rotation base point. In this case, when moving from the inner side surface 14 to the rear side surface 15, the suction nozzle tends to move to the downstream side GD <b> 1 that approaches the rear side surface by the rotation trajectory. It is possible to follow.

  It is conceivable that the beverage container 1 rotates due to contact with the suction nozzle. Therefore, when the beverage container is a polygonal cylinder as in this embodiment, guides that prevent the beverage container from rotating due to contact with the suction nozzle are provided on both sides in the width direction of the transport path 20. It is preferable.
