Description

  The present invention relates to a method and an apparatus for purifying a filler filling a container such as a bottle by washing and sterilizing while rotating a large number of filling nozzles.

  A filler, which is a filling machine that fills a large number of bottles with beverages, includes a large number of filling nozzles arranged at a constant pitch along a circumference in a predetermined horizontal plane. Since this filler fills the sterilized beverage so that foreign substances such as microorganisms do not enter the sterilized bottle, the whole is stored in the sterilization chamber.

  When filling a beverage, all the filling nozzles of the filler are swung at a high speed all at once, and the beverage is poured into the bottles that come synchronously in a certain amount. As described above, since the filler is stored in the aseptic chamber, the beverage is filled aseptically.

  The beverage is supplied from the blender to the filler filling nozzle through the beverage supply system pipe, and the inside of the beverage supply system pipe is regularly or when the beverage type is changed, CIP (Cleaning in It is subjected to a Place (Place) process to remove residues and foreign matters, and is further subjected to a SIP (Sterilizing in Place) process for sterilization (see, for example, Patent Documents 1, 2, and 3).

  CIP is performed by flowing a cleaning liquid in which an alkaline agent such as sodium hydroxide is added to water, for example, in a flow path from the inside of the beverage supply system pipe to the filling nozzle of the filling machine. Thereby, the residue etc. of the last drink adhering in the drink supply system piping line are removed (for example, refer patent documents 1, 2, and 3).

  SIP is performed, for example, by flowing steam, hot water, or the like in a pipe line cleaned with the CIP, and the inside of the beverage supply system pipe is sterilized by heating with steam, hot water, or the like (for example, Patent Documents). 3 See paragraph 0003.)

  When CIP and SIP are performed with a liquid such as a cleaning liquid or hot water in the beverage supply system piping, it is performed as follows.

  Since it is necessary to circulate the liquid in the beverage supply system piping or to collect the waste liquid, the cup is put on the nozzle opening of each stationary filling nozzle. A cup is arrange | positioned so that rotation with a filling nozzle is possible. A manifold that swirls together with the filling nozzle and the cup is provided in advance around the swiveling axis of the swirling movement of the filling nozzle. The cup is connected to the manifold by a pipe line, and the manifold, the cleaning liquid storage tank, and the pump are connected by a pipe line that can be intermittently connected. The cleaning liquid storage tank and pump are secured to the filler frame or aseptic chamber.

  When CIP or SIP is performed in the beverage supply system piping, the swivel movement of the filling nozzle and manifold is stopped, and the cup is automatically placed over the nozzle opening, so that the cup communicates with the manifold, and the manifold and the cleaning liquid. The storage tank is connected by a pipe line. Accordingly, the cleaning liquid flows from the cleaning liquid storage tank into the beverage supply system piping, and further flows into the filling nozzle, the nozzle port, the cup, and the manifold, and circulates within a predetermined time. Thereby, CIP inside a drink supply system piping or a filling nozzle is performed. When SIP is performed with a liquid such as hot water, hot water or the like is flowed into the supply system pipe or the filling nozzle in the same manner as the CIP, and the supply system pipe or the inside of the filling nozzle is sterilized. The

  In the aseptic chamber, COP (Cleaning out of Place) and SOP (Sterilizing out of Place) are performed for purification (see, for example, Patent Documents 4, 5, and 6).

  Various injection nozzles are arranged at various locations in the sterilization chamber, and when COP and SOP are performed, chemicals such as alkaline cleaning agents, peracetic acid cleaning agents, hydrogen peroxide water, and aseptic water are supplied from these nozzles. It is sprayed in the form of spray or shower in order in the aseptic chamber. By this chemical solution, water mist, shower, etc., the inner wall surface of the sterilization chamber and the surface of the equipment such as the filler are purified and sterilized.

JP 2007-331801 A JP 2000-153245 A Japanese Patent Laid-Open No. 2007-22600 Japanese Patent No. 3315918 JP 2004-299723 A JP 2010-189034 A

  As described above, when performing CIP and SIP in the beverage supply system pipe, the manifold and the supply source of the cleaning liquid are connected by a pipe line, so that the swiveling motion of the filling nozzle or the like in the filler is stopped. Therefore, when CIP or SIP is performed on the beverage supply system piping, if COP or SOP is also performed at the same time in the aseptic chamber, the cleaning liquid or sterilizing liquid does not reach the outer surface of the filler uniformly, resulting in poor cleaning and sterilization. It tends to occur. In particular, since the filling nozzle has a complicated shape and structure, it tends to cause poor cleaning and sterilization. In addition, since the filling nozzle is a part that fills the bottle with a beverage, there is a high risk of entering the bottle if microorganisms or foreign substances remain on the surface of the filling nozzle.

  Therefore, conventionally, the COP and SOP for the inside of the aseptic chamber have been completed after the CIP and SIP for the beverage supply system piping have been completed and the pipe line between the manifold and the storage tank for the cleaning liquid has been disconnected, It is done in a possible state. That is, when the filler is driven and the various nozzles in the sterilization chamber spray the cleaning liquid etc. while the filling nozzle is swirling, spraying and showering of the cleaning liquid etc. is performed throughout the filler, especially every corner of the filling nozzle. It will spread and the filler will be properly cleaned and sterilized.

  However, if COP and SOP are performed in the aseptic chamber after the completion of CIP and SIP for the beverage supply system piping, the downtime (production stop time) of the filler and the entire aseptic filling apparatus becomes long, and the beverage stuffing container Productivity is reduced.

  Accordingly, it is an object of the present invention to provide a filler cleaning method and apparatus capable of solving the above-mentioned problems, and the present inventor has reduced the number of nozzles installed in an aseptic chamber in order to reduce downtime. After increasing, COP and SOP in the aseptic chamber were tried at the same time as CIP and SIP in the beverage supply system piping.

  In order to solve the above problems, the present invention employs the following configuration.

  In addition, although the code | symbol of drawing is attached | subjected with a parenthesis in order to make this invention easy to understand, this invention is not limited to this.

That is, in the invention according to claim 1, the predetermined working fluid is ejected from the fixed spray nozzle (17a) in a predetermined order in the aseptic chamber (9) in which the filler (1) is accommodated, whereby the COP and the SOP. one or performs both, when performing one or both of the COP and SOP, so blow toward the outer surface of the filler (1) a predetermined working fluid in a predetermined order, the beverage filler (1) in For the beverage supply system pipe (2) to be sent to the filler, when one or both of CIP and SIP are performed in a state where the filler (1) is stopped, the filler performs one or both of the COP and SOP in parallel with this. Adopt the purification method.
The invention according to claim 2 is provided with a fixed injection nozzle (17a) for performing one or both of COP and SOP by ejecting a predetermined working fluid in a predetermined order in an aseptic chamber (9) containing a filler. is, when executing one or both of COP and SOP, so blow toward the outer surface of the filler (1) from the fixed injection nozzle (17a) a predetermined working fluid in a predetermined order, beverage fillers ( 1) When one or both of CIP and SIP are performed in a state where the filler (1) is stopped with respect to the beverage supply system pipe (2) to be sent into the inside, one or both of the COP and SOP are parallel to this. Adopt a filler purification device that is designed to perform the above.

  According to the present invention, the predetermined working fluid can be distributed to every corner of the outer surface of the filler (1) accommodated in the aseptic chamber (9). COP and SOP can be implemented. In particular, since the filling nozzle (7) in the filler (1) has a complicated shape and structure, poor cleaning and sterilization are likely to occur. However, according to the present invention, the filling nozzle (7) on the surface of the filling nozzle (7) It is possible to prevent microorganisms and foreign matters from remaining, and to eliminate the danger of the microorganisms and foreign matters entering the container such as the bottle (b).

  Moreover, in this invention, when performing one or both of CIP and SIP in the state which stopped the filler (1) about the drink supply system piping (2) which sends a drink into a filler (1), it is parallel with this. Since one or both of the COP and SOP is performed, one or both of the COP and SOP can be performed at the same time as one or both of the CIP and SIP. The production stop time of the aseptic filling device such as the filler (1), the production time at the time of switching beverages can be shortened, and the production efficiency can be increased.

BRIEF DESCRIPTION OF THE DRAWINGS It is the schematic of the filler and aseptic chamber which are the objects which are cleaned by the filler cleaning method which concerns on this invention, The left half shows the state during drink filling, and the right half shows the state in the process of washing | cleaning or sterilization.

  Embodiments of the present invention will be described below with reference to the drawings.

  The aseptic filling apparatus is provided with a beverage supply system pipe 2 for supplying a beverage from a blending tank (not shown) of the beverage to the filler 1 shown in FIG. In FIG. 1, the code | symbol 3 shows the surge tank provided in the middle of the drink supply system piping.

  Further, the aseptic filling apparatus is provided with a bottle conveyance path for conveying a bottle b, which is a container for filling a beverage, to the filler 1 and conveying the bottle b filled with the beverage by the filler 1 to a capper (not shown). The conveyance path is generally constituted by a plurality of rows of wheels, grippers 4 arranged around each wheel, and the like.

  The filler 1 is a filling machine that fills a large number of bottles b with a beverage at a high speed, and includes a wheel 5 that constitutes a part of the conveyance path of the bottles b as shown in FIG. The wheel 5 is attached to a portion of the support shaft 6 that stands upright from the floor surface of the aseptic filling device as a turning shaft 6a. Around the wheel 5, grippers 4 that hold the neck of the bottle b are arranged at a constant pitch. The gripper 4 is integrated with the wheel 5 and can turn in one direction. A large number of filling nozzles 7 arranged at the same pitch as the grippers 4 are attached around the wheel 5.

  The upper part where the rotation of the support shaft 6 is stopped is fixed to the machine frame of the filler 1, and a rotary joint 6b is provided between the upper end of the turning shaft 6a. Further, an upper manifold 8 is provided below the rotary joint 6b in the turning shaft 6a. The portion from the upper portion of the support shaft 6 to the upper manifold 8 is hollow, and the beverage supply system pipe 2 is connected to the upper portion of the support shaft 6. Also, the beverage supply system pipe 2 extends from the upper manifold 8 to each filling nozzle 7.

  When the filler 1 is operated, the wheel 5 swivels at a high speed, and when the bottle b gripped by the gripper 4 is conveyed at high speed on the conveyance path in synchronization with this movement, the bottle 5 comes immediately below the nozzle port 7a of the filling nozzle 7. Each bottle b is filled with a certain amount of beverage one after another.

  Further, since the filler 1 is filled with the sterilized beverage so that foreign substances such as microorganisms do not enter the sterilized bottle b, as shown in FIG. The The aseptic chamber 9 is provided with an inlet and an outlet of the bottle b on the upstream side and the downstream side of the conveyance path of the bottle b, but these are not shown.

  As described above, the beverage is supplied from the blending device to the filling nozzle 7 of the filler 1 through the beverage supply system pipe 2. The inside of the beverage supply system pipe 2 is regularly or the type of the beverage. When switching, CIP processing is performed, and further SIP processing is performed.

  CIP is performed by passing cleaning fluids such as water, alkaline detergent, and acidic detergent through the beverage supply system pipe 2 in a predetermined order. SIP is performed by passing a sterilizing working fluid such as a sterilizing liquid, hot water, or steam through the beverage supply system pipe 2.

  In FIG. 1, the code | symbol 10 shows the storage tank as a supply source of the working fluid which is a washing | cleaning liquid and a disinfection liquid, and the code | symbol 11 shows a liquid feeding pump. The storage tank 10 is provided in a number corresponding to a predetermined type of working fluid, but only one is shown in the drawing. Further, illustration of the supply source of the working fluid for sterilization such as steam is omitted. Further, in FIG. 1, reference numeral 12 indicates an outward pipe extending from the storage tank 10 to the surge tank 3, and reference numeral 13 indicates a return pipe extending from each filling nozzle 7 to the storage tank 10. The outgoing pipe 12 and the return pipe 13 together with the beverage supply system pipe 2 form a circulation path for cleaning liquid and the like.

  At the start end of the return pipe 13, there are provided cups 14 that can be brought into and out of contact with the nozzle openings 7 a of the respective filling nozzles 7. When performing CIP or SIP, each cup 14 is put on the nozzle port 7a at the tip of the filling nozzle 7 of the filler 1 by an actuator (not shown), so that the starting end of the return pipe 13 is connected to the nozzle port 7a of the filling nozzle 7. . Each cup 14 is connected to the lower manifold 15 by a flexible pipe that forms part of the return pipe 13. The lower manifold 15 is attached to the swivel shaft 6a of the filler 1 and can swivel integrally with the wheel 5, the filling nozzle 7, and the like.

  An intermittent joint 16 is provided at a location where the return pipe 13 extends from the lower manifold 15 to the storage tank 10. The joint 16 is connected during the CIP or SIP. In that case, the wheel 5, the filling nozzle 7, etc. cannot turn. When the CIP or SIP is finished and the joint 16 is disconnected, the wheel 5, the filling nozzle 7 and the like can turn.

  Similar to CIP and SIP performed in the beverage supply system pipe 2, COP and SOP are also performed in the aseptic chamber 9 for purification.

  COP and SOP are performed by spraying a predetermined working fluid such as a chemical solution such as hydrogen peroxide water or sterile water in the aseptic chamber 9 in a spray or shower form.

  In FIG. 1, reference numerals 17 a and 17 b indicate spray nozzles arranged in various locations between the inner wall surface of the sterilization chamber 9 and the outer surface of the filler 1 in the sterilization chamber 9.

  Among the injection nozzles, the reference numeral 17a is a fixed injection nozzle fixed at a predetermined position in the sterilization chamber 9, and the reference numeral 17b is a movable injection nozzle movable in the vertical direction.

  As shown in FIG. 1, a large number of movable injection nozzles 17 b are arranged at a constant pitch inside an annular pipe 18 that is arranged so as to surround the filler 1 from the outer periphery thereof. The annular pipe 18 having the movable spray nozzle 17b can be provided not only in one stage but also in a plurality of stages. These movable spray nozzles 17b are desirably arranged so as to face the filling nozzle 7, respectively.

  The annular pipe 18 is held by the vertical reciprocating means and can be reciprocated in the vertical direction along the outer periphery of the filler 1 by driving the vertical reciprocating means. Specifically, as shown in FIG. 1, it is connected to a rod 19 a of an air cylinder device 19 which is an actuator fixed vertically to the machine frame of the filler 1 or the wall of the aseptic chamber 9. Desirably, the air cylinder device 19 is fixed to the outside of the ceiling of the sterilization chamber 9, and the rod 19 a protrudes into the sterilization chamber 9. For this reason, between the inner wall surface of the sterilization chamber 9 and the rod 19a, the outside air is blocked by the bellows 20 so as not to enter the sterilization chamber 9. Although only two air cylinder devices 19 are shown in the illustrated example, three or more air cylinder devices 19 may be provided.

  Reference numeral 21 denotes a storage tank which is a supply source of a predetermined working fluid such as an alkaline cleaning agent, a peracetic acid cleaning agent, a chemical solution such as hydrogen peroxide solution, and sterile water. The storage tank 21 is provided for each of a chemical solution such as hydrogen peroxide solution and sterile water, but only one is shown for convenience. Reference numeral 22 denotes a supply pipe extending from each storage tank 21 to the fixed injection nozzle 17a, and reference numeral 23 denotes a flexible supply pipe extending from each storage tank 21 to the movable injection nozzle 17b. Specifically, the flexible supply pipe 23 is connected to the annular pipe 18. Each supply pipe 22, 23 is provided with a pump 24.

  During CIP or SOP, the air cylinder device 19 is driven to cause the annular pipe 18 to reciprocate up and down along the outer periphery of the filler 1 together with the rod 19a. At the same time, a predetermined working fluid such as a chemical solution for CIP or SOP and aseptic water is sprayed from the movable spray nozzle 17b toward the outside of the filler 1 in a predetermined order. The foreign material is washed off from the outer surface of the filler 1 and sterilized.

  Note that the stroke of the annular pipe 18 in the vertical direction can be set so that the outer surface of only the filling nozzle 7 in the filler 1 can be traced in the vertical direction. In this way, the filling nozzle 7 having a particularly complicated shape and structure can be cleaned and sterilized more carefully than the other parts.

  Next, purification work by the filler purification device will be described.

  (1) The driving of the filler 1 is stopped, whereby the filling nozzle 7 and the like stop rotating and stop. Further, the surge tank 3 is emptied.

  (2) As shown in the right half of FIG. 1, the nozzle opening 7 a of the filling nozzle 7 is closed by the cup 14. A joint 16 is connected. As a result, a circulation path for flowing a predetermined working fluid such as a cleaning liquid and a sterilizing liquid is formed during CIP and SIP.

  (3) CIP is started, and a predetermined working fluid such as an alkaline cleaner and water is sent out from the storage tank 10 by the pump 11 in a predetermined order. The cleaning liquid or the like flows from the storage tank 10 to the surge tank 3 through the forward pipe 12, flows into the upper manifold 8 through the beverage supply system pipe 2, and then flows to the filling nozzles 7. It returns to the storage tank 10 through the pipe 13. Accordingly, the cleaning liquid or the like flows in the circulation path in a predetermined order for a predetermined time, and the inside of the beverage supply system pipe 2 including the inside of the filling nozzle 7 is cleaned.

  (4) When CIP ends, SIP is started, and a predetermined working fluid such as hot water or heated steam is caused to flow through the circulation path for a predetermined time. Thereby, the inside of the beverage supply system pipe 2 including the filling nozzle 7 and the like is sterilized.

  (5) When CIP and SIP are performed, COP and SOP are performed in the sterilization chamber 9 in parallel.

  COP and SOP are performed by sending a predetermined working fluid such as a cleaning liquid and a sterilizing liquid from each storage tank 21 by a pump 24 in a predetermined order. The cleaning liquid or the like is sprayed from the fixed spray nozzle 17 a and the movable spray nozzle 17 b through the supply pipes 22 and 23 in the form of a spray or a shower, and is sprayed on the outer surface of the filler 1 or the like in the aseptic chamber 9.

  The movable spray nozzle 17b sprays cleaning liquid, sterilizing liquid, and the like toward the outside of the filler 1 in a predetermined order while reciprocating in the vertical direction of the filler 1 together with the annular pipe 18 by driving the air cylinder device 19. Thereby, the washing | cleaning effect of the outer surface of the filler 1, especially the outer surface of the filling nozzle 7 which has a complicated shape and structure improves.

  Moreover, since COP and SOP are performed in parallel with CIP and SIP, the downtime of the aseptic filling apparatus including the filler 1 is shortened, and the productivity of the beverage stuffed product is improved.

  Note that COP and SOP for the inside of the sterilization chamber 9 may be performed after the CIP and SIP are performed. In this case, after the joint 16 is separated, COP and SOP are preferably performed while the filler 1 is making a swiveling motion. It is possible to enhance the cleaning effect and the sterilizing effect by spraying the cleaning liquid, the sterilizing liquid and the like to the place where the filling nozzle 7 is swiveling at a high speed together with the filler 1.

  (6) When the CIP, SIP, COP, and SOP are finished, the joint 16 connected for the CIP and SIP is divided, and as shown in the left half of FIG. The cup 14 is removed.

  (7) The beverage filling operation is started, and the beverage which has been prepared and sterilized by a preparation device (not shown) passes through the purified surge tank 3 and the beverage supply system pipe 2 into the filler 1, Each bottle b which is a container is filled from each filling nozzle 7.

  The bottle b filled with the beverage is transferred from the gripper 4 on the wheel 5 side of the filler 1 to the gripper on the wheel side of the next capper (not shown). It is discharged out of the device.

  Although the present invention is configured as described above, the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the gist of the present invention.

  For example, the movable filling nozzle may be erected from the floor side of the aseptic filling device. The chamber is not limited to the aseptic specification, and may be a shroud structure used in a clean room or the like. The container is not limited to a bottle but may be a paper container.

  In the above embodiment, when both CIP and SIP are performed on the beverage supply system piping and the like, both COP and SOP are performed in the aseptic chamber. However, when CIP is performed, COP is performed and CIP is performed. Perform SOP when performing CIP, perform both COP and SOP when perform CIP, perform COP when performing SIP, perform SOP when performing SIP, and perform both COP and SOP when performing SIP COP may be performed when both CIP and SIP are performed, and SOP may be performed when both CIP and SIP are performed.
