Definitions

  • the present invention relates to an apparatus and a method for charging viscous fluid which is capable of quickly and assuredly charging the viscous fluid into containers by a predetermined quantity for use in a charging and wrapping field for charging fluid into the containers.
  • viscous fluid for example, ketchup, mayonnaise or sauce
  • ketchup mayonnaise or sauce
  • fluid in a fluid supply tank 51 is supplied to a measuring vessel 52 by a predetermined quantity to be measured.
  • a delivery piston 53 disposed in the measuring vessel 52 charges the fluid from a nozzle 55 into a container 57 positioned on a table 56 via a pipe 54 (see Fig. 3).
  • the fluid supplied into the measuring vessel 52 by a predetermined quantity is measured in the measuring vessel 52 by a so-called "capacity control method". Therefore, if the accuracy in the capacity of the molded container 57 is unsatisfactory (in particular, if the container 57 is made of glass), the fluid levels of the fluid charged into each container 57 by a predetermined quantity cannot be made the same among the containers 57. Therefore, the charged containers 57 put on show in a shop, to the contrary to the fact, impress persons that the containers 57 are defective products of a type lacking for a predetermined quantity. Hence, the quality of the containers 57 deteriorates considerably.
  • the fluid levels in the containers can be made the same among the containers by employing a charging method of a type controlling the fluid level.
  • the fluid level of the viscous fluid cannot be flattened in the container after the fluid has been discharged through the nozzle.
  • the raised fluid level is maintained for a long time.
  • the fluid Since the raised portion of the fluid is sucked up by the suction pipe in the charging method of a type controlling the fluid level, the fluid cannot be charged into the container by a predetermined quantity.
  • the method of supplying the fluid with pressure encounters a considerable dispersion of the fluid level, a difficulty in controlling the pressure for supplying the fluid and the impossibility of controlling the charging speed at the time of the completion of the charging operation. Therefore, the phenomenon of the rise of the fluid level cannot be overcome.
  • the present invention is directed to overcome the foregoing problems and therefore an object of the present invention is to provide an apparatus and a method of charging viscous liquid with which the viscous fluid can be charged into containers while uniforming the fluid levels even if the capacities of the containers are not the same by an arrangement that a delivery pipe having an upper portion communicating with a supply chamber for viscous fluid formed in a frame and having an opened lower portion is allowed to hang from the lower portion of the frame, a fluid supply hole connected to fluid supply means is formed in one of the surfaces of the supply chamber of the frame, a valve is disposed in the supply chamber of the frame to allow and stop the flow of the fluid by the vertical movement of a valve rod of the valve realized by opening/closing means, a suction port connected to suction means and communicating with a draft hole of a draft passage of the valve rod is formed in one of the surfaces of the suction chamber in the frame, and a suction pipe for sucking excess fluid is disposed in the delivery pipe.
  • viscous fluid can be efficiently be charged by a predetermined quantity in a short time while making the fluid levels to be the same even if containers have dispersed capacities. Therefore, the quality as the product can be improved when the containers are put on show in a shop.
  • the delivery of the viscous fluid by means of the fluid supply means is performed at a high speed to supply a large quantity immediately before the completion of the charging operation into the container and then the viscous fluid is supplied at a low speed by a small quantity, the time taken to complete the charging operation can be shortened considerably. Further, the rise of the fluid level in the container at the time of the completion of the charging operation can be prevented. Therefore, excess removal of the viscous fluid can be prevented, and accordingly, a peculiar effect can be obtained in that the fluid can be charged accurately.
  • symbol A represents an apparatus for charging viscous fluid for use in a charging and wrapping field and so forth.
  • the apparatus A performs a process for charging viscous fluid, such as ketchup, mayonnaise or sauce, by a predetermined quantity into a container made of glass or plastic, the apparatus being basically constituted by a charging nozzle c and fluid supply means d.
  • the charging nozzle c comprises a frame 1, a delivery pipe 2, a fluid supply hole 3, a valve rod 4, a valve 5, an opening/closing means 6, a suction chamber 7, a suction port 8, a draft hole 9 and a suction pipe 10.
  • the foregoing frame 1 is fastened to a support member 11 while including a hollow space to form a supply chamber 12 into which viscous fluid is introduced from a fluid supply means d to be described later.
  • the support member 11 can be moved arbitrarily and vertically for a predetermined stroke by an elevating means 14 fastened to a frame 13. As a result, the delivery pipe 2 and the suction pipe 10 can be introduced into the container b filled with the fluid and ejected from the same.
  • the elevating means 14 is moved upwards/downwards by the operation of an air cylinder 15 secured to the frame 13 and having a rod 16 fastened to the support member 11.
  • an air cylinder 15 secured to the frame 13 and having a rod 16 fastened to the support member 11.
  • a conventional means of a cam type or a thread type using a servo motor or the like is employed.
  • the delivery pipe 2 is formed into a hollow shape hanging from the lower portion of the frame 1 by a predetermined length such that the upper portion of the delivery pipe 2 communicates with the supply chamber 12.
  • the lower portion of the delivery pipe 2 is opened to enable the viscous fluid to be delivered.
  • the fluid supply hole 3 is so formed in one of the surfaces of the supply chamber 12 in the frame 1 as to communicate with the fluid supply means d.
  • the valve rod 4 is inserted into the frame 1 as to be capable of moving upwards/downwards by the opening/closing means 6 while being concentric with the delivery pipe 2, the valve rod 4 being formed into a hollow shape so that a draft passage 17 is formed which has the opened lower end portion.
  • the valve 5 is disposed in the supply chamber 12 of the frame 1 to allow/stop the flow of the fluid by the vertical movement of the valve rod 4 thereof.
  • the valve 5 has a sealing surface to be brought into contact with a valve seat 18 positioned in the lower portion of the supply chamber 12 so that the supply chamber 12 is closed.
  • the opening/closing operation of the valve rod 4 of the valve 5 is performed by the opening/closing means 6.
  • opening/closing means 6 may be a known means such as a fluid cylinder or an electromagnetic solenoid.
  • the opening/closing means 6 has an operation member which is connected to the upper end portion of the valve rod 4.
  • the suction chamber 7 is so formed in the upper portion of the supply chamber 12 in the frame 1 as to surround the inserted valve rod 4.
  • the valve rod 4 has the draft hole 9 formed in the upper portion of the draft passage 17 thereof, the draft hole 9 facing the suction chamber 7.
  • the suction port 7 is opened in one of the surfaces of the suction chamber 7 so that the suction port 7 is connected to a suction means 19 such as a blower pump or a vacuum pump.
  • the suction pipe 10 is inserted into the delivery pipe 2 so that the suction pipe 10 is able to move upwards/downwards in the delivery pie 2.
  • the upper portion of the suction pipe 10 is fastened to the lower end of the valve rod 4, while the lower end of the same has a sealing member 20 which substantially coincides with the shape of the lower end portion of the delivery pipe 2 when the valve 4 closes the supply chamber 12.
  • the suction force of the suction means 19 therefore acts on the lower opening of the suction pipe 10 via the draft hole 9 and the draft passage 17 so that the fluid in the container b is sucked up.
  • reference numeral 21 represents a guide for the container b arranged to press the opening portion of the container b placed on a retainer frame 22 in order to prevent an undesirable movement of the container b occurring at the time of the fluid charging operation.
  • the guide 21 for the container b is so fastened to a connection rod 23 connected to an elevating member (omitted from illustration) as to be capable of moving upwards/downwards.
  • the fluid supply means d supplies the fluid to the charging nozzle c by a predetermined quantity, that is, a quantity desired to be injected into the container b.
  • the fluid supply means d supplies the fluid in a fluid supply tank 24 to a measuring means 26 via a closing valve 26. After a predetermined quantity of the fluid has been measured, the fluid is, under pressure, supplied to the fluid supply hole 3 of the supply chamber 12 via a pipe 28 by a delivery means 27.
  • the measuring means 26 has a cylinder 29 an end portion of which is connected to the closing valve 25, the cylinder 29 including a suction/discharge piston 30. Therefore, when the closing valve 25 is opened and the piston is moved downwards, the fluid in the fluid supply tank 24 is introduced into the cylinder 29.
  • the delivery means 27 moves upwards/downwards the suction/discharge piston 30 to introduce/deliver the fluid.
  • An elevating member 32 connected to an operation rod 31 positioned in the lower portion of the suction/discharge piston 30 is moveably received by a support guide 33.
  • a drive member 36 such as a servo motor which can be numerically controlled, the suction/discharge piston 30 can be moved by a predetermined quantity.
  • the charging speed and the quantity of the fluid delivered from the delivery pipe 2 can be determined.
  • a preparation for the charging operation is completed when the lower portion of the delivery pipe 2 of the charging nozzle c is moved downwards by the elevating means 14 to be inserted into the container b.
  • the measuring means 2 of the fluid supply means d measures the quantity of the fluid which is determined while considering the capacity of the container b.
  • the closing valve 25 is opened to move downwards the suction/discharge piston 30 by the delivery means 27, the fluid in the fluid supply tank 24 is introduced into the cylinder 29.
  • the stroke corresponding to the quantity of the rotation of the servo motor 36 is given to the suction/discharge piston 30. As a result, a desired quantity of the fluid to be charged is set.
  • valve 5 opened by the opening/closing means 6 causes the fluid to be charged into the container b from the lower portion of the delivery pipe 2.
  • the control means to which the predetermined data has been set operates the foregoing delivery means 27 to considerably reduce the quantity of the fluid to be injected as compared with the initial quantity. Therefore, the fluid is charged by a small quantity so that the raised level of the viscous fluid supplied into the container b due to the previous charging operation is gradually flattened. Further, rise of the fluid level can be prevented.
  • the fluid can be charged to a predetermined level while maintaining the flat level.
  • the operation for charging the fluid performed by the measuring means 26 charges the fluid into the container b by an excessive quantity. Therefore, the fluid level is raised excessively.
  • the suction pipe 10 included in the delivery pipe 2 is used to act the suction force by the suction means 19 (the suction force may be previously given or it may be operated by the control means after a predetermined charging operation has been performed) . As a result, the fluid is sucked by a quantity corresponding to the raised level from the lower end of the suction pipe 10. Therefore, the excess fluid in the container b can be removed.
  • the suction portion in the lower portion of the suction pipe 10 is adjusted to a predetermined height by the elevating means 14. Therefore, even if the capacities of the containers b are not the same, the fluid levels in a multiplicity of the arranged containers b can always be made coincide with a line.
  • the opening/closing means 6 acts to close the valve 5.
  • the suction pipe 10 is, at this time, also moved upwards to close the delivery passage of the delivery pipe 2 by the sealing member 20 thereof so that the fluid is stopped and the fluid leakage is prevented.
  • the discharging speed and the quantity of the fluid realized by the delivery means 27 can be arbitrarily determined by properly adjusting the moving speed of the piston 30 in accordance with a command to be issued to the control means. Therefore, the speed and the quantity can be determined to be adaptable to the conditions and the like of the fluid to be charged.
  • the apparatus A according to this embodiment of the present invention can, of course, be used as a normal piston-type charger which does not use the suction means 19.
