  A container clamping structure and a container cleaning apparatus according to a first embodiment of the present invention will be described with reference to the drawings. In the present embodiment, an example in which the container clamping structure is applied to a container cleaning apparatus is shown.

  The “container” to be cleaned by the container cleaning device means a container or barrel used when filling a liquid such as beer, wine or soft drink. However, the liquid filled in the container or barrel is not limited to the liquid for beverages, and includes liquids for industrial use such as agriculture and industry and medical liquids.

  As shown in FIGS. 1 to 4, the container cleaning apparatus 10 mainly includes a head unit 12 for placing the container 1, a tank unit 14 for storing a detergent solution T (see FIG. 4, the same applies hereinafter), and a head unit. 12, a valve unit 16 for controlling the supply of the detergent liquid T to the tank 12, a pump unit 18 for supplying the detergent liquid T stored in the tank unit 14 to the valve unit 16, a head unit 12, the tank unit 14, the valve unit 16 or a pump.

Have.

  As shown in FIGS. 1 and 11, the head portion 12 includes, for example, a disk-shaped plate portion 26 and a clamper cylinder portion 72 for raising and lowering the plate portion 26. A container 1 to be cleaned is placed on the upper surface of the plate portion 26. The clamper cylinder part 72 is a mechanism for adjusting the height of the plate part 26 when the neck part 3 of the container 1 is clamped, for example.

  As shown in FIGS. 11 to 13, a guide portion 74 is provided on the upper surface of the plate portion 26. The guide portion 74 is formed in a predetermined arc shape in a plan view shown in FIG. The guide part 74 has an arcuate base part 78 protruding from the upper surface of the plate part 26, and an arcuate contact part 76 provided on the upper surface of the base part 78. The inner edge 76 </ b> A of the contact part 76 protrudes radially inward from the inner edge 78 </ b> A of the base part 78. Then, the inner edge 76 </ b> A of the contact portion 76 of the guide portion 74 contacts the neck portion 3 of the container 1 to position the container 1 with respect to the connection probe 80 and the plate portion 26.

  The head part 12 includes a connection port part 82. A connection probe 80 that can be expanded and contracted from the inside of the connection port portion 82 is disposed inside the connection port portion 82. In the connection port portion 82, for example, a flow path (not shown) for guiding the detergent liquid T to the inside of the container 1 and a flow path (not shown) for discharging the detergent liquid T to the outside of the container 1 are formed. ing. A probe cylinder portion 84 is connected to the connection probe 80, and the piston of the probe cylinder 84 presses the connection probe 80 to move the connection probe 80 in the vertical direction. A mouth seal portion 82A is provided at the tip of the connection port portion 82. A probe packing 80 </ b> A is provided at the tip of the connection probe 80.

  The clamper cylinder portion 72 and the probe cylinder portion 84 include, for example, a cylinder main body that accommodates a fluid such as gas or liquid, and a piston that is extendable and contractable from the cylinder main body. The piston is driven by receiving a force such as air pressure or hydraulic pressure.

  The number of clamper cylinders 72 may be one or more. In addition, the number of probe cylinders 84 corresponds to the number of connection probes 80.

  As shown in FIG. 15, the clamper cylinder part 72 and the probe cylinder part 84 can be driven and controlled by the control unit 20.

  Here, as shown in FIGS. 13 and 14, the plate portion 26 moves in the vertical direction together with the guide portion 74. The plate portion 26 is configured to be movable relative to the connection port portion 82 along the vertical direction. Further, the connection probe 80 is configured to be movable relative to the connection port portion 82 along the vertical direction.

  As shown in FIGS. 3 and 5, the head unit 12 includes a cleaning process detection unit 60 that shows a trace of the cleaning process of the container 1. The cleaning process detection unit 60 is electrically connected to the control unit 20 or the operation unit 22. The detection result of the cleaning process detection unit 60 can be output to the control unit 20 or the operation unit 22.

  As shown in FIG. 6, the cleaning process detection unit 60 is preferably a flow detection sensor 62 that detects the presence or absence of the cleaning process by detecting the flow of the detergent liquid T flowing inside the head unit 12. Similarly, the flow detection sensor 62 is electrically connected to the control unit 20 or the operation unit 22. The detection result of the flow detection sensor 62 can be output to the control unit 20 or the operation unit 22.

  Here, a first embodiment of the cleaning process detection unit 60 will be described. As shown in FIG. 7, in the first embodiment, a temperature sensor 64 and a pressure sensor 66 are employed as the cleaning process detection unit 60, that is, the flow detection sensor 62. The temperature sensor 64 and the pressure sensor 66 are attached to the head unit 12 and detect a flow trace of the detergent liquid T in a flow path inside the head unit 12.

  Specifically, the temperature sensor 64 detects the temperature of the flow path of the head unit 12. Since the detergent liquid T is heated to a predetermined temperature, it is possible to determine whether the detergent liquid T has flowed through the flow path of the head unit 12 based on the detection result of the temperature sensor 64. The detection result by the temperature sensor 64 is output to the cleaning process specifying unit 58 or the operation unit 22 of the control unit 20.

  Moreover, it is preferable to manage the temperature of the detergent liquid T based on the temperature result of the temperature sensor 64. When the temperature of the detergent liquid T is lower than the allowable temperature, the detergent power of the detergent liquid T is reduced. On the other hand, when the temperature of the detergent liquid T is higher than the allowable temperature, the cost required for heating the detergent liquid T increases. For this reason, by controlling the temperature of the detergent liquid T to an allowable temperature based on the temperature result by the temperature sensor 64, it is possible to achieve both improvement of the cleaning effect and cost reduction. Note that feedback control may be performed based on the temperature result from the temperature sensor 64 so that the temperature of the detergent liquid T becomes an allowable temperature.

  The pressure sensor 66 detects the pressure in the flow path of the head unit 12. A predetermined pressure (water pressure) is generated when the detergent liquid T flows through the flow path of the head part 12, and therefore it is possible to determine whether the detergent liquid T has flowed through the flow path of the head part 12 based on the detection result of the pressure sensor 66. become. The detection result by the pressure sensor 66 is output to the cleaning processing specifying unit 58 or the operation unit 22 of the control unit 20.

  Moreover, it is preferable to manage the pressure of the detergent liquid T based on the pressure result by the pressure sensor 66. When the pressure of the detergent liquid T is lower than the allowable pressure, the detergent liquid T is not sufficiently supplied to the inside of the container 1 and the cleaning effect may be reduced. For this reason, based on the pressure result by the pressure sensor 66, the cleaning effect can be enhanced and maintained by managing the pressure of the detergent liquid T to an allowable pressure. Note that feedback control may be performed based on the pressure result from the pressure sensor 66 so that the pressure of the detergent liquid T becomes an allowable pressure.

  As one aspect of the fluidity detection sensor, a fluid sensor or a flow rate sensor can be used. As shown in FIG. 8, in the second embodiment, a fluid sensor 68 and a pressure sensor 66 are employed as the cleaning process detection unit 60, that is, the flow detection sensor 62. The fluid sensor 68 and the pressure sensor 66 are attached to the head unit 12 and detect the trace of the flow of the detergent liquid T flowing through the flow path inside the head unit 12.

  The fluid sensor 68 detects the presence or absence of fluid. Specifically, the fluid sensor 68 takes heat when the fluid is flowing regardless of the liquid or gas, and senses this change to monitor whether the liquid or gas is flowing. Since the fluid sensor 68 has no moving parts, the fluid flow can be monitored with stable operation for a long period of time.

  The flow sensor is a sensor that detects the amount of flow of water, pure water, air, gas, chemicals, steam, and the like. For example, an impeller type that applies the measurement fluid to the impeller and converts the number of revolutions to a flow rate value, a float type that detects the flow rate based on the degree of lift in a pipe installed in the vertical direction, and Faraday's law There are various detection principles such as electromagnetic.

  As an example of a fluid sensor or a flow rate sensor, a sensor capable of detecting a flow rate by measuring strain generated in a metal plate by a flow pressure with a strain gauge can be applied.

  A configuration including all of the temperature sensor 64, the pressure sensor 66, and the fluid sensor 68 may be employed, or a configuration including any two sensors may be employed. Moreover, the structure provided only with any one of the temperature sensor 64, the pressure sensor 66, and the fluid sensor 68 may be sufficient. Moreover, it may replace with the fluid sensor 68, and the structure provided with the flow sensor (illustration omitted) independently or with the other sensor may be sufficient.

  By providing and detecting a plurality of sensors among the temperature sensor 64, the pressure sensor 66, and the fluid sensor 68, the flow of the detergent liquid T can be reliably specified, and a highly accurate determination result can be obtained.

  The cleaning process detection unit 60 is not limited to the above sensors. As the cleaning process detection unit 60, for example, a CCD camera or the like may be provided for monitoring.

  As shown in FIG. 4, the tank part 14 has the storage part 28 formed in the hollow shape, for example. A predetermined amount of the detergent liquid T is stored in the storage unit 28.

  The tank unit 14 includes a heating unit 34 for heating the detergent liquid T stored in the storage unit 28. The heating unit 34 is constituted by a heater, for example. By cleaning the detergent liquid T and adjusting it to a high temperature, the cleaning power of the detergent liquid T is increased. The heating unit 34 is driven and controlled by the control unit 20.

  The tank unit 14 includes a temperature detection unit 36 for detecting the temperature of the detergent liquid T stored in the storage unit 28. The temperature detection part 36 is comprised with a temperature sensor, for example. The temperature detection result of the temperature detection unit 36 is output to the control unit 20.

  Note that the temperature detection unit 36 is not necessarily indispensable, but is necessary, for example, when feedback control is performed on the temperature control of the detergent solution T.

  The tank unit 14 has a water level detection unit 38 for detecting the water level of the detergent liquid T stored in the storage unit 28. The water level detection part 38 is comprised with a level switch, for example. The water level detection result by the water level detection unit 38 is output to the control unit 20.

  When the water level detection unit 38 detects that the water level of the detergent liquid T is lower than the predetermined water level, the control unit 20 stops driving the heating unit 34 and the pump unit 18. Thereby, emptying and baking can be prevented.

  Note that the water level detection unit 38 is not necessarily an essential configuration, but is required when, for example, the water level of the detergent liquid T in the storage unit 28 is controlled to be constant.

  The tank portion 14 has a water injection cover 40 that protrudes to the inner surface side of the storage portion 28. The water injection cover 40 guides the used detergent liquid T flowing out from the second discharge side pipe 56 to the bottom side of the reservoir 28. Thereby, since the used detergent liquid T can be reused for cleaning the container 1, energy saving can be achieved. Moreover, by using the water injection cover 40, the detergent liquid T can be discharged smoothly.

  A predetermined wall for causing the detergent liquid T to collide is provided at a predetermined portion of the water injection cover 40. When the detergent liquid T discharged to the reservoir 28 collides with the wall of the water injection cover 40, the detergent liquid T is reduced in momentum, and air is removed from the interior of the detergent liquid T colliding with the wall. Thereby, air (air) is removed also from the inside of the detergent liquid T stored in the storage part 28. As a result, air components in the detergent liquid supplied from the reservoir 28 to the supply side block 44 of the valve unit 16 can be reduced or eliminated, and downstream inconvenience can be avoided.

  The tank unit 14 includes a detergent pipe 42 that protrudes toward the inner surface side of the storage unit 28. The detergent pipe 42 is connected to the return pipe 50, and the detergent liquid T flowing through the return pipe 50 is discharged from the outlet of the detergent pipe 42. Since the tip of the detergent pipe 42 is located in the water of the detergent liquid T stored in the reservoir 28, when the detergent liquid T is discharged from the tip of the detergent pipe 42, the detergent liquid T stored in the reservoir 28 is Stir. By this stirring action, the temperature of the detergent liquid T stored in the reservoir 28 becomes uniform, and the temperature control of the detergent liquid T becomes accurate.

  The control unit 20 has a function of controlling the temperature of the detergent liquid T. In other words, the control unit 20 drives and controls the heating unit 34 so that the temperature of the detergent solution T always becomes a predetermined value (optimum value) based on the temperature of the detergent solution T detected by the temperature detection unit 36. . Thereby, the feedback control regarding the temperature of the detergent liquid T is implement | achieved.

  Note that the temperature control function of the control unit 20 is not an essential configuration, but is necessary when feedback control is performed on the temperature control of the detergent liquid T, for example.

  Instead of the temperature control function of the control unit 20, a temperature control unit may be newly provided, and thereby the temperature control of the detergent liquid T may be executed.

  As shown in FIGS. 7 to 10, the control unit 20 includes a cleaning process specifying unit 58. The cleaning process specifying unit 58 specifies whether or not the cleaning process of the container 1 has been executed. The cleaning process specifying unit 58 mainly includes a CPU 58A, a ROM 58B, and a RAM 58C.

  The CPU 58 </ b> A determines the presence / absence of a cleaning process for the container 1 based on the detection result output from the temperature sensor 64, the pressure sensor 66, or the fluid sensor 68. When the CPU 58A specifies the presence or absence of the cleaning process for the container 1, a cleaning process determination program or the like is stored in the ROM 58B in advance, and the detection result output from the temperature sensor 64, the pressure sensor 66, or the fluid sensor 68 and the cleaning process are stored. The presence or absence of a cleaning process is determined based on the determination program.

  Note that a predetermined threshold is defined in the cleaning processing determination program, and the CPU 58A of the control unit 20 determines the magnitude relationship between the detection result output from the temperature sensor 64, the pressure sensor 66, or the fluid sensor 68 and the threshold. Based on this, it is preferable to determine whether or not the container 1 has been cleaned.

  In the ROM 58B or RAM 58C, the detection results output from the temperature sensor 64, pressure sensor 66, or fluid sensor 68 are stored as a cleaning record. The ROM 58B appropriately stores the above-described cleaning processing determination program.

  The CPU 58A may be configured not to determine whether or not the container 1 is subjected to the cleaning process. In this case, based on the detection result output from the temperature sensor 64, the pressure sensor 66, or the fluid sensor 68, the operator determines whether or not the container 1 is cleaned.

  Here, as shown in FIGS. 9 and 10, a configuration in which a printing unit 70 electrically connected to the control unit 20 is provided may be employed. The printing unit 70 may be built in the control unit 20 or the operation unit 22, or may be provided separately from the control unit 20 or the operation unit 22.

  The printing unit 70 prints information on the cleaning process on predetermined paper. The information related to the cleaning process may indicate, for example, a determination result of the cleaning process by the CPU 58A, or may indicate the detection result (detection data) itself output from the temperature sensor 64 and the pressure sensor 66.

  Instead of printing by the printing unit 70 or along with printing by the printing unit 70, information on the above-described cleaning process may be displayed on a liquid crystal display (not shown) of the operation unit 22.

  As shown in FIGS. 1 to 3, the valve unit 16 includes, for example, a plurality of cylinder valve units 30 and a valve mounting block 32 to which the cylinder valve units 30 are mounted.

  The cylinder valve unit 30 supplies the detergent liquid T to the head unit 12 based on a control signal from the control unit 20. Thereby, the inside of the container 1 placed on the plate part 26 of the head part 12 can be cleaned.

  The valve mounting block 32 is configured to allow fluid to flow therethrough. The valve mounting block 32 has a supply side block 44 and a discharge side block 46. The supply side block 44 circulates the detergent solution T in the process of supplying the detergent solution T in the tank unit 14 to the container 1 placed on the head unit 12. In the discharge side block 46, the detergent liquid T circulates in the process of returning the detergent liquid T that has washed the container 1 on the head part 12 to the tank part 14.

  The pump unit 18 is, for example, a drive source for pumping up the detergent liquid T stored in the storage unit 28 of the tank unit 14 and supplying it to the valve unit 16 side. When the cleaning process of the container 1 is started, the driving of the pump unit 18 is preferably continued without being stopped, except for exceptions such as errors and accidents. As a result, the detergent solution T that cannot enter the supply side block 44 of the valve unit 16 can be returned to the inside of the storage unit 28 of the tank unit 14 via the return pipe 50. As a result, the internal pressure can be reduced by releasing the internal pressure of the first supply side pipe 48, and as a result, breakage and malfunction of the first supply side pipe 48 can be prevented.

  The control unit 20 is a so-called control box, and controls at least one drive of the head unit 12, the tank unit 14, the valve unit 16, the pump unit 18, or the operation unit 22. The control unit 20 controls the overall operation of the container cleaning device 10. For this reason, it becomes possible to automatically control the cleaning process inside the container 1 by driving the control unit 20.

  The control unit 20 supplies power necessary for driving each component to the head unit 12, the tank unit 14, the valve unit 16, the pump unit 18, and the operation unit 22.

  The operation unit 22 includes equipment such as operation buttons, a liquid crystal display, and a liquid crystal panel, and operates, for example, driving of the control unit 20. By performing a predetermined operation with the operation unit 22, the control unit 20 is driven and the cleaning process of the container 1 is started. The operation unit 22 may have a configuration other than the control unit 20, for example, a configuration that directly controls driving of the head unit 12, the tank unit 14, the valve unit 16, and the pump unit 18.

  The operation unit 22 is connected to, for example, the support base 24 of the container cleaning device 10. However, the operation part 22 may be directly connected to the support base part 24, or may be attached to the support base part 24 via a predetermined connecting member. Further, the operation unit 22 may be provided in any of the head unit 12, the tank unit 14, the valve unit 16, the control unit 20, or the pump unit 18.

  The operation unit 22 is located in the vicinity of the head unit 12. By providing the operation unit 22 at a position where the distance between the operation unit 22 and the head unit 12 is shortened, the operator moves to the operation unit 22 after placing the container 1 on the plate unit 26 of the head unit 12. The distance and time until it is shortened. Thereby, after placing the container 1 on the plate part 26 of the head part 12, the operator can immediately operate the operation part 22, so that the efficiency of the cleaning process of the container 1 can be significantly increased.

  The supply side block 44 and the tank unit 14 are connected by a first supply side pipe 48. The first supply side pipe 48 supplies the detergent solution T stored in the tank unit 14 to the supply side block 44 of the valve unit 16. A return pipe 50 connected to the tank unit 14 is connected in the middle of the first supply side pipe 48. The return pipe 50 returns a part of the detergent liquid T flowing through the first supply side pipe 48 to the inside of the tank part 14 without supplying the part to the valve part 16.

  The supply side block 44 and the head unit 12 are connected by a second supply side pipe 52. The second supply side pipe 52 supplies the detergent liquid T from the supply side block 44 of the valve unit 16 to the head unit 12. The detergent liquid T supplied to the head unit is supplied to the container 1 on the head unit 12 and used for cleaning.

  The discharge side block 46 and the head unit 12 are connected by a first discharge side pipe 54. The first discharge side pipe 54 supplies the used detergent solution T used for cleaning the container 1 from the head unit 12 to the discharge side block 46 of the valve unit 16.

  The discharge side block 46 and the tank unit 14 are connected by a second discharge side pipe 56. The second discharge side pipe 56 supplies the used detergent liquid T discharged from the head unit 12 to the discharge side block 46 of the valve unit 16 to the tank unit 14.

  Next, the arrangement (layout) of each component of the container cleaning device 10 will be described.

  As shown in FIG. 2, the outer shape of the tank unit 14 and the control unit 20 is formed in, for example, a square shape, and the outer shape of the plate unit 26 of the head unit 12 is formed in, for example, a round shape.

  The control unit 20 is located in a space SP1 that faces the one side surface 14A of the tank unit 14. In other words, the one side surface 14A of the tank portion 14 faces the space portion SP1. Thus, the control unit 20 is adjacent to the tank unit 14.

  The pump unit 18 is located in the space SP1 facing the one side surface 14A of the tank unit 14 in the same manner as the control unit 20. The pump unit 18 is adjacent to the tank unit 14 and is also adjacent to the control unit 20 at the same time. In other words, the pump unit 18 is located in a region surrounded by the tank unit 14, the control unit 20, and the head unit 12.

  The valve portion 16 is located in the space portion SP1 facing the one side surface 14A of the tank portion 14 in the same manner as the control portion 20 and the pump portion 18. The valve unit 16 is adjacent to the pump unit 18 and is also adjacent to the control unit 20 and the head unit 12 at the same time.

  The head portion 12 is located in a space portion (space) SP <b> 2 facing the corner portion 14 </ b> C of the tank portion 14. In other words, the centers of the plate part 26 of the head part 12 and the storage part 28 of the tank part 14 are arranged so as to be located on the diagonal extension of the storage part 28 of the tank part 14 in plan view. The head portion 12 is arranged so as to protrude not only from the one side surface 14A of the tank portion 14 but also from the other side surface 14B substantially orthogonal to the one side surface 14A of the tank portion 14.

  The corner portion 14C of the tank portion 14 is a corner portion formed by intersecting the end portion of the one side surface 14A and the end portion of the other side surface 14B.

  The operation portion 22 is located in a space portion (space) SP3 which is a dead space facing the other side surface 14B substantially orthogonal to the one side surface 14A of the tank portion 14. In other words, the other side surface 14B of the tank portion 14 faces the space portion SP3. For this reason, it is possible to arrange the operation unit 22 using a dead space due to the provision of the head unit 12, and at the same time, it is possible to position the operation unit 22 in the vicinity of the head unit 12. As a result, the separation distance between the head unit 12 and the operation unit 22 is shortened.

  Thus, space part SP1-SP3 comprises the L-shaped line LL by planar view.

  In other words, the control unit 20, the pump unit 18, the valve unit 16, the head unit 12, and the operation unit 22 are positioned side by side on the L-shaped line LL in plan view around the tank unit 14. The arrangement order of the control unit 20, the pump unit 18, the valve unit 16, the head unit 12, and the operation unit 22 is not particularly limited, but the head unit 12 and the operation unit 22 are preferably adjacent to each other. .

  By adopting the above layout for each component of the container cleaning device 10, the control unit 20, the pump unit 18, the valve unit 16, the head unit 12, and the operation unit 22 are provided around the tank unit 14 by using a dead space. It can arrange efficiently. As a result, the entire apparatus can be reduced in size, and the installation area of the container cleaning apparatus 10 can be reduced.

  In addition, after the container 1 is placed on the plate part 26 of the head part 12, the movement distance of the worker required to reach the operation part 22 is shortened. For this reason, after placing the container 1 on the plate part 26 of the head part 12, the time until it is operated by the operation part 22 is shortened, and the efficiency of the cleaning process of the container 1 can be increased.

  In particular, since the control unit 20, the pump unit 18, the valve unit 16, the head unit 12, and the operation unit 22 are positioned side by side on the L-shaped line LL in plan view, the container cleaning device 1 The layout efficiency and design can be improved, and the distance between the head portion 12 and the operation portion 22 can be shortened.

  Next, the container clamping structure in the container cleaning apparatus 10 according to one embodiment of the present invention will be described.

  As shown in FIG. 14, the container 1 is turned upside down and placed on the upper surface of the plate portion 26 (FIG. 14A). Then, the container 1 is moved horizontally along the upper surface of the plate portion 26, and the neck 3 of the container 1 is brought into contact with the inner edge 76A of the contact portion 76 of the guide portion 74 (FIG. 14B). At this time, since the weight of the container 1 is supported by the plate portion 26, the horizontal movement of the container 1 becomes smooth. Moreover, since the guide part 74 is formed in a circular arc shape, the container 1 can be easily and reliably captured by the guide part 74. The container 1 captured by the guide portion 74 is positioned relative to the connection port portion 82 and the connection probe 80. Thereby, positioning along the horizontal direction of the container 1 is completed.

  Next, the clamper cylinder part 72 is driven by the control part 20, and the plate part 26 is lowered in the direction of gravity. At this time, the plate portion 26 is lowered together with the guide portion 74. Eventually, the connection port portion 82 and the connection probe 80 enter the through hole 26 </ b> A formed substantially at the center of the plate portion 26. The tip of the neck 3 of the container 1 is supported by the mouth seal portion 82A of the connection port 82 from below, and at the same time, the tip of the neck 3 of the container 1 is the contact portion 76 between the mouth seal 82A and the guide 74. (FIG. 14 (C)). Thereby, the positioning along the vertical direction of the container 1 is completed.

  Thus, the positioning of the container 1 along the horizontal direction and the vertical direction is completed, and the container 1 and the connection port portion 82 are completely connected.

  Thereafter, the probe cylinder 84 is driven by the controller 20 to raise the connection probe 80 vertically upward (FIG. 14D). Then, the detergent solution T is supplied into the container 1 through the connection probe 80 or the connection port 82 during a predetermined cleaning process.

  According to the clamp structure of the container 1 and the container cleaning device 10 of the present embodiment, the plate part 26 is moved by the one kind of clamper cylinder part 72 in a state where the plate part 26 is positioned along the horizontal direction by the guide part 74. By descending together with the container 1, the neck 3 of the container 1 is eventually supported by the connection port 82. At the same time, the neck portion 3 of the container 1 is sandwiched between the guide portion 74 and the connection port portion 82 along the vertical direction. For this reason, the container 1 can be reliably connected to the connection port portion 82 without being displaced, and the number of parts is reduced as compared with the conventional configuration in which the container is clamped using a plurality of types of cylinders. it can.

  Further, by moving the container 1 in the horizontal direction on the plate part 26, the container 1 can be captured by the guide part 74 while the gravity of the container 1 is supported by the plate part 26. Further, the neck portion 3 of the container 1 can be held between the guide portion 74 and the connection port portion 82 simply by lowering the container 1 in the vertical direction according to the action of gravity by the cylinder portion 72 for clamper. For this reason, the container 1 can be easily and accurately clamped.

  In particular, when the contact portion 76 of the guide portion 74 contacts over a predetermined circular arc of the neck portion 3 of the container 1, the effect of capturing the container 1 by the guide portion 74 is enhanced, and consequently the positioning accuracy of the container 1 is increased.

  Next, the flow of the detergent liquid in the container cleaning device 10 according to the embodiment of the present invention will be described.

  As shown in FIGS. 1 to 4, the container 1 is placed on the plate portion 26 of the head portion 12. Thereafter, the control unit 20 is driven by operating the operation unit 22. The pump unit 18 is driven by the control unit 20, and the detergent liquid T stored in the storage unit 28 of the tank unit 14 is pumped up and supplied to the valve unit 16.

  Here, while the detergent solution T stored in the reservoir 28 of the tank unit 14 is pumped up by the operation of the pump unit 18 and flows through the first supply side pipe 48, a part thereof enters the return pipe 50. Then, a part of the detergent liquid T travels through the return pipe 50 and is poured into the reservoir 28 via the detergent pipe 42. Since the tip of the detergent pipe 42 is located in the water of the detergent liquid T, when the detergent liquid T is discharged from the outlet of the detergent pipe 42, the detergent stored in the reservoir 28 due to the pressure of the jet A vortex is generated in the liquid T. Thereby, the detergent liquid T stored in the storage part 28 is stirred. As a result, the temperature unevenness of the detergent liquid T stored in the storage unit 28 is eliminated, and the temperature becomes uniform.

  The remaining detergent liquid T reaches the supply side block 44 of the valve unit 16. The valve unit 16 is driven by the control unit 20, and a predetermined amount of detergent liquid T is supplied to the head unit 12 through the supply side block 44 and the cylinder valve unit 30. Then, the detergent liquid T is supplied to the inside of the container 1 placed on the plate part 26 of the head part 12, and the inside of the container 1 is cleaned.

  The used detergent solution T that has washed the container 1 is supplied to the discharge side block 46 through the first discharge side pipe 54, and then discharged to the storage part 28 of the tank unit 14 through the second discharge side pipe 56. Is done. The detergent liquid T discharged to the reservoir 28 is reused in the next cleaning process.

  As described above, after the container 1 is placed on the plate part 26 of the head part 12, the cleaning of the container 1 is started by automatic control by the control unit 20. When the predetermined process is completed, the pump unit 18 automatically pumps up the detergent solution T and the supply of the detergent solution T from the cylinder valve unit 30 of the valve unit 16 to the head unit 12 is stopped by the automatic control by the control unit 20. The cleaning process ends. As a result, a series of cleaning processes from the start to the end of cleaning of the container 1 can be automatically controlled by the control unit 20.

  Further, the container 1 cleaned by the container cleaning device 10 has a high cleaning effect because the inside of the container 1 is cleaned by the detergent liquid T.

  Here, the detergent solution T stored in the storage unit 28 of the tank unit 14 is heated and controlled by the heating unit 34. Thereby, the temperature of the detergent liquid T becomes high and the cleaning power of the detergent liquid T becomes high. As a result, the cleaning effect of the container cleaning device 10 is enhanced.

  Further, the temperature of the detergent liquid T in the storage section 28 of the tank section 14 is detected by the temperature detection section 36, and the heating section 34 is controlled based on the detection result so that the temperature of the detergent liquid T becomes an optimum value. . Thereby, feedback control regarding the temperature of the detergent liquid T becomes possible, and the temperature of the detergent liquid T can always be maintained at the optimum temperature. As a result, the high cleaning power of the detergent liquid T can be maintained.

  In particular, the detergent liquid T in the reservoir 28 is agitated by returning a part of the detergent liquid T to the reservoir 28 of the tank 14 by the return pipe 50. Thereby, the temperature unevenness of the detergent liquid T in the reservoir 28 is eliminated, and the temperature becomes uniform. As a result, there is no deviation between the actual temperature of the detergent liquid T and the detected temperature by the temperature detector 36, and accurate feedback control is possible with respect to the temperature control of the detergent liquid T. And the state with the high temperature of the detergent liquid T can be implement | achieved reliably, and the high cleaning power of the detergent liquid T can be maintained.

  Next, the cleaning process determination of the detergent liquid of the container cleaning apparatus 10 according to the embodiment of the present invention will be described.

  As shown in FIGS. 5 to 10, the temperature sensor 64, the pressure sensor 66, or the fluid sensor 68 outputs a detection result indicating whether or not the detergent liquid T has flowed through the flow path of the head unit 12. For example, temperature information is detected by the temperature sensor 64, pressure information is detected by the pressure sensor 66, and information regarding the presence or absence of fluid is detected by the fluid sensor 68.

  In the configuration in which the presence or absence of the cleaning process is determined by the CPU 58A, the presence or absence of the cleaning process is determined by the detection result of the temperature sensor 64, the pressure sensor 66, or the fluid sensor 68 and the cleaning process determination program.

  In the configuration in which the CPU 58A does not determine whether or not the cleaning process is performed, the operator determines whether or not the cleaning process is performed with reference to the detection result of the temperature sensor 64, the pressure sensor 66, or the fluid sensor 68.

  The detection results of the temperature sensor 64, the pressure sensor 66, or the fluid sensor 68 are printed on a sheet by the printing unit 70 and output, or displayed on the liquid crystal display of the operation unit 22.

  Instead of the detection results of the temperature sensor 64, the pressure sensor 66, or the fluid sensor 68, or together with the detection results of the temperature sensor 64, the pressure sensor 66, or the fluid sensor 68, the determination result of the cleaning process by the CPU 58A is performed by the printing unit 70. It may be printed on paper and output, or displayed on the liquid crystal display of the operation unit 22.

  As described above, whether or not the detergent liquid T is flowing through the flow path of the head unit 12 by referring to or analyzing the detection result of the temperature sensor 64, the pressure sensor 66, or the fluid sensor 68 or the determination result of the cleaning process by the CPU 58A. Can be determined.

  The fact that the detergent liquid T was flowing in the flow path of the head portion 12 means that the detergent liquid T was supplied to the inside of the container 1, and the history of cleaning processing or technical evidence. To demonstrate its abilities. That is, it proves that the cleaning process of the container 1 is completed.

  As described above, the conventional technology relates to the cleaning process of the container 1 and the process of the cleaning process cannot be visually recognized unless the container is transparent. However, by adopting the above-described configuration as in the present embodiment of the present invention, it is possible to technically prove the cleaning process of the container 1. As a result, it is possible to provide a third party with information regarding the cleaning process of the container 1 as a cleaning record, together with confirmation of whether the cleaning process of the container 1 has been performed.

  In particular, by using the temperature sensor 64, the pressure sensor 66, and the fluid sensor 68 as the flow detection sensor 62, these sensors can be easily obtained, the presence of the detergent liquid T can be determined, and the reliability of the cleaning record is improved. be able to.

  The embodiment described above is merely an example for explaining the present invention, and various modifications can be made without departing from the gist of the present invention.
