Definitions

  • the invention rotates to a packaging machine according the precharacterizing part of claim 1.
  • Such a packaging machine has been disclosed in FR-A-2.120.765.
  • preformed containers which are closed at their bottom ends, are supplied to the subchamber via a chute.
  • a rotatable wheel is arranged with support means for supporting the containers and for displacing said containers along nozzle means toward a discharge opening.
  • said nozzle means are supplied sterilizing fluid and hot air for drying the sterilized containers.
  • tubular blanks before being supplied to the main chamber for a series of packaging operations, are fed to the subchamber, which is separate from the main chamber, are then sterilized in the subchamber and are thereafter fed to the main chamber.
  • the blank existing in the subchamber while being sterilized, is in the form of a tube with its both ends not yet closed, so that the blank is more evenly sterilized in its entirety than, for example, the blank that is closed at its one end. Further, the portions to be closed at the after-treatment can also be sterilized. This assures complete sterilization of the blanks.
  • the blank is supplied to the conveyor disposed in the sterilizing compartment in order to sterilize the blank, sprayed with sterilizing solution while being transported on the conveyor, and then fed to another conveyor arranged in the drying compartment separate from the sterilizing compartment. Thereafter, hot air is blown to the blank while the latter is being transported by the conveyor. This ensures thorough working of sterilizing solution and hot air on the blanks.
  • the packaging machine is closed when stopping its operation, so that both chambers are kept at the specified positive pressure, even if the air generation apparatus stops working, since the air supply pipe is automatically closed by the check valve. Further, should the pressures within both chambers lower for some reasons, the detector detects this pressure drop to operate the apparatus for producing clean air, whereby both chambers are kept at a predetermined positive pressure. Thus both chambers can be prevented from being polluted due to inflow of air.
  • the packaging machine to be described below comprises two rows of components, and the components of one row are identical with those of the other row. Throughout the drawings, like parts are referred to by like reference numerals.
  • the packaging machine is adapted for use with tubular paper blanks for packaging.
  • a thermoplastic synthetic resin layer is formed on the inner and outer sides of each blank.
  • the packaging machine comprises an endless conveyor 1 and a mandrel wheel 4 disposed above the starting end of the path of transport of the conveyor 1 and having a horizontal rotary shaft 2 and eight mandrels 3 extending radially from the shaft 2.
  • the conveyor 1 and the mandrel wheel 4 are intermittently driven in synchronism.
  • the conveyor 1 comprises a pair of chains 5 movable in circulation in a horizontal plane, a multiplicity of holders 6 attached to the chains 5 at a predetermined spacing and a rail 7 for supporting the bottoms of bottomed tubular blanks C.
  • the blanks C are transported by the conveyor 1 from the rear forward as indicated by an arrow A.
  • the mandrel wheel 4 is driven counterclockwise in Fig.
  • the conveyor 1 and the mandrel wheel 4 are entirely enclosed in a closed main chamber 8.
  • the main chamber 8 is filled with clean air which has been sterilized.
  • a series of devices 9 are arranged on the top wall of the main chamber 8 from the rear forward in succession. These devices include primary and secondary bottom heaters 10, 11 for heating the end of the tubular blank C to be made into the bottom of a container, a bottom breaker 12 for folding the end to a flat form, a bottom sealer 13 for pressing the flatly folded end, a primary top breaker 14 for forming folds in the other end of the tubular blank C so as to render the end easily foldable into a roof form to provide the top of the container, a filling device 15 for filling a predetermined amount of contents into the bottomed tubular blank C, a secondary top breaker 16 for eventually folding the end in the form of a roof along the folds formed by the primary top breaker 14, a top heater 17 for heating the end thus folded and a top sealer 18 for pressing the end.
  • the primary and secondary bottom heaters 10, 11, the bottom breaker 12 and the bottom sealer 13 are arranged at the positions where the mandrels stop.
  • the portions of the group of devices 9 which operate on the blank C extend into the main chamber 8.
  • the wall portions of the main chamber 8 through which these operating portions of the devices extend into the main chamber are completely prevented from passing air therethrough with use of bellows for the operating portion which performs a reciprocating rectilinear motion or with use of an oil seal or mechanical seal for the operating portion which performs a rotary motion.
  • the series of devices 9 are all those already known.
  • the main chamber 8 is internally provided with a cleaning-sterilizing system 19 and a clean air supply system 20.
  • a closed subchamber 22 is disposed to the rear of the main chamber 8 and made to communicate therewith by a booth 21.
  • a blank sterilizer 23 and a blank transfer assembly 24 are arranged within the subchamber 22.
  • a blank shaping-feeding unit 25 is provided outside the subchamber 22.
  • the blank shaping-feeding unit 25 is enclosed in its entirety in a rear chamber 26 which, however, is not of closed construction unlike the chambers 8 and 22.
  • the unit 25, which is of the known type, is adapted to shape folded flat blanks C into a tubular form.
  • the unit 25 includes a magazine 27 having stacked therein a multiplicity of folded flat blanks C although now shown.
  • the blank transfer assembly 24 is adapted to transfer blanks C shaped to a tubular form from the blank shaping-feeding unit 25 to the blank sterilizer 23 and to transfer sterilized tubular blanks C from the sterilizer 23 to the mandrel wheel 4.
  • the cleaning-sterilizing system 19 comprises spray nozzles 28, spray balls 29 and sterilizing solution spray nozzles 30 which are arranged within the main chamber 8 as required.
  • the conveyor 1 is operated with a cleaning solution forced out from the spray nozzles 28 and balls 29, whereby the conveyor 1 and the interior of the main chamber 8 can be cleaned automatically.
  • a sterilizing solution when applied by the spray nozzles 30, sterilizes the conveyor 1 and the interior of the main chamber 8.
  • An aqueous solution of hydrogen peroxide with a concentration of 35% is used as the sterilizing solution.
  • Fig. 5 shows the clean air supplying system 20.
  • the main chamber 8 has a completed container discharge opening 31 at the front end thereof.
  • the subchamber 22 has a blank supply opening 32 at a rear portion thereof. These openings 31 and 32 are provided with openable closures 33 and 34 respectively.
  • Branched air supply ducts 36 extending from an air supply unit 35 are connected to. the main chamber 8 and the sub- chamber 22 and are each provided with a check valve 37.
  • the air supply unit 35 comprises an air intake filter 38, an electric blower 39, a sterilizing filter 40 and a heater 41.
  • An air discharge duct 42 is connected to suitable portions of the main chamber 8 and the subchamber 22 and is open to the atmosphere through a shutoff valve 43.
  • the system 20 is further provided with a pressure sensor 44 for detecting the internal pressure of the main chamber 8, such that when the pressure detected drops below a set level, the air supply unit 35 operates in response to an output signal from the sensor 44.
  • the air supply duct 36 is also connected to the blank sterilizer 23 (see Figs. 6 to 8).
  • the supply ducts 36 are shut off from the chambers 8, 22 by the check valves 37 and separated from the atmosphere by the sterilizing filter 40, so that the ducts 36 are made free from contaminants. This eliminates the need for routine sterilization of the supply ducts 36. If the internal pressure of the chambers 8, 22 decreases for one cause or another, the sensor 44 detects the pressure drop to operate the electric blower 39 and to thereby maintain the interior of the chambers 8, 22 at the specified positive pressure level at all times.
  • Figs. 6 to 8 show the subchamber 22 and the blank sterilizer 23 in detail.
  • the subchamber 22 comprises a drying compartment 46 having at its front portion a blank outlet 45 communicating with the main chamber 8, a sterilizing compartment 49 communicating at its front portion with the drying compartment 46 through an opening 47 and having a blank inlet 48 at its rear portion, and a pressurized compartment 50 enclosing an opening, including the blank inlet 48, of the sterilizing compartment 49.

  • the sterilizing conveyor 52 is so disposed within the sterilizing compartment 49 that each of the holders 60 travels passing a position opposed to the communication opening 47 and the blank inlet 48.
  • Both the drying and sterilizing blank holders 58 and 60 are of the same shape and comprise a plurality of horizontal pieces to be positioned around the tubular blank C to retain the blank C in a horizontal position, restraining the blank from upward or downward movement but allowing the blank to move forward or rearward.
  • the hot air blowing nozzles 53 are attached to a hot air supply duct 61 extending vertically within the drying compartment 46 and are arranged at the same spacing as the drying blank holders 58.
  • the orifices of the nozzles 53 are directed in the axial direction of the holders 58.
  • the upper end of the duct 61 extends through the top wall of the drying chamber 46 upward, with a heat insulating tube 62 provided around the duct 61.
  • the top end of the duct 61 has the air supply duct 36 connected thereto and a burner 63 attached thereto.
  • the nozzle 54 for spraying a solution for sterilizing the blank is mounted on the bottom of a bottomed tube 64.
  • the tube 64 extends in the front-to-rear direction across the drying compartment 46 so as to be positioned in front of and in alignment with each of the sterilizing blank holders 60 when the holder 60 depends from the rotary shaft 59.
  • the tube 64 is provided in the drying compartment 46 with its open end communicating with the sterilizing compartment 49.
  • the orifice of the spray nozzle 54 is oriented in the axial direction of the blank holder 60.
  • the drive sprockets 55 of the drying conveyor 51 are fixed to a rotary shaft 65 extending from the rear wall of the drying compartment 46 forward through the front wall thereof.
  • a pulley 66 is fixedly mounted on the end of the shaft 65 projecting outward from the compartment 46.
  • a belt 67 is reeved around the pulley 66 and another pulley fixed to the output shaft of an unillustrated prime mover.
  • the drying conveyor 51 is intermittently driven by the belt 67 so that the holders 58 thereon can be stopped at the positions opposed to the blank outlet 45 and the communication opening 47.
  • the horizontal rotary shaft 59 of the sterilizing conveyor 52 is supported by a tube 68 attached to the rear end of the drying compartment 46.
  • the front end of the rotary shaft 59 extends into the drying compartment 46, and drive sprockets 69 are fixed to the front end.
  • the sprockets 69 are in mesh with the endless chains 57 so that the holders 60 of the sterilizing conveyor 52 can be stopped at the position opposed to the communication opening 47 and the blank outlet 48.
  • the sterilizing conveyor 52 is intermittently driven in synchronism with the drying conveyor 51.
  • the drive interval is 90 degrees in terms of the revolution of the holders 60, i.e. one pitch of the holders 60.
