Description

  The present invention relates to a filling nozzle attached to a filling machine or the like that fills a container with a viscous liquid such as cream cheese, and a method for producing a container-containing viscous liquid.

  Generally, when a viscous liquid material such as cream cheese is filled in a tray-like container, a filling nozzle that matches the shape and size of the container is attached to the outlet end of the flow path to which the viscous liquid material is supplied (for example, , See Patent Document 1). In addition, the viscous liquid material is filled by intermittently transporting the container with a certain interval, and when the container is positioned below the filling nozzle, the viscous liquid material is quantitatively discharged from the discharge port of the filling nozzle. Is called. If the container is not located below the filling nozzle, the viscous liquid cannot be poured into the container, and therefore the filling operation is not performed.

Japanese Patent Application Laid-Open No. 07-327606

  When the container is filled with the viscous liquid material using the filling nozzle, the entire amount of the viscous liquid material in the filling nozzle is not charged into the container, and a part of the viscous liquid material remains in the filling nozzle. After the filling operation is finished, the viscous liquid material remaining in the filling nozzle may communicate with the atmosphere and gradually drop downward from the discharge nozzle outlet at an unintended timing. The dripping of the viscous liquid material from the discharge port of the filling nozzle at such an unintended timing is called dripping.

  If dripping occurs while the container is being transported toward the lower side of the filling nozzle, viscous liquid material adheres to the outside of the container, the transport path of the container, or the like. In addition, if the leaked viscous liquid adheres to the flange part of the tray-like container, then when the lid is heat-welded to the container and sealed, defective products such as poor thermal welding or burnt kogation of the viscous liquid Will occur.

  Containers and products with dripping viscous liquid material are defective products that cannot be provided to consumers, so the manufacturer must remove the product from the production line, and the labor and equipment costs for product inspection are low. It was necessary.

  Therefore, an object of the present invention is to provide a filling nozzle capable of suppressing dripping of a viscous liquid material such as cream cheese and a method for producing a viscous liquid material in a container.

  As a result of earnestly examining the above problems, the present inventor determined that the gravity applied to the viscous liquid remaining in the filling nozzle is greater than the frictional force between the viscous liquid and the inner wall of the filling nozzle, or the shearing force between the viscous liquids. It was found that dripping occurred when it became larger. The present invention has been made based on the above findings.

  That is, the filling nozzle according to the present invention is a filling nozzle attached to a filling machine for filling a viscous liquid material into a container, a flow path through which the viscous liquid material circulates, a discharge port from which the viscous liquid material is discharged, The discharge port has a deformed elliptical shape with a constriction at the center.

  In this filling nozzle, the discharge port has a deformed elliptical shape with a constriction at the center. For this reason, compared with the case where a discharge port is a perfect circle shape or an ellipse shape, the center part of a discharge port can be brought close to the inner wall of a filling nozzle. That is, the frictional force of the viscous liquid material located at the center of the discharge port with respect to the inner wall of the filling nozzle forming the flow path is made closer to the frictional force of the viscous liquid material located near the inner wall of the filling nozzle with respect to the inner wall of the filling nozzle. Can do. Thereby, it is possible to prevent the viscous liquid material from dripping. As a result, for example, when a viscous liquid material is filled in a container that is intermittently transported, it is possible to prevent the viscous liquid material from adhering to the outside of the container, the transport path of the container, and the like to be contaminated. In addition, for example, when filling a liquid container in a tray-like container, products such as poor thermal welding at the time of container sealing or burnt kogation of the viscous liquid substance caused by the viscous liquid substance attached to the flange of the container Defects can be suppressed.

  By the way, when a discharge port is a perfect circle shape or an ellipse shape, the viscous liquid substance with which a container is filled spreads radially from one point located on the centerline of a discharge port. And since the fluidity | liquidity of a viscous liquid substance is low, when filling a rectangular container with a viscous liquid substance, there exists a problem that a viscous liquid substance is hard to be filled with the four corners of a container. However, in this filling nozzle, since the discharge port has a deformed elliptical shape with a constriction at the center, a small amount of viscous liquid material is discharged from the center of the discharge port, and a large amount from both ends of the discharge port sandwiching the constriction. The viscous liquid material is discharged. As a result, the viscous liquid filled in the rectangular container spreads radially from two points separated from each other. Therefore, even if the fluidity of the viscous liquid is low, the four corners of the rectangular container are easily filled with the viscous liquid. Become.

  You may further provide the contact member arrange | positioned at the flow path in the front-end | tip part of a filling nozzle, and contacted with the viscous liquid substance which distribute | circulates a flow path. In this filling nozzle, a contact member that is in contact with the viscous liquid material flowing through the flow path is disposed in the flow path at the tip of the filling nozzle. As a result, the viscous liquid remaining in the filling nozzle comes into contact with the contact member at the tip of the filling nozzle, so that the viscous liquid can be further prevented from dripping.

  The contact member may be disposed at a position passing through the constriction when viewed from the discharge port side to divide the flow path. In this filling nozzle, the contact member is disposed at a position passing through the constriction in the center as viewed from the discharge port side, and the flow path is divided. For this reason, it is possible to equalize the influence of the frictional force acting on the viscous liquid material at both ends of the discharge port sandwiching the constriction, and to suppress the dripping from one end.

  The method for producing a viscous liquid material in a container according to the present invention is to carry the container into the filling machine equipped with the above-mentioned filling nozzle and discharge the viscous liquid material from the filling nozzle when the container is located below the filling nozzle. Then, the container is filled with the viscous liquid material, the discharge of the viscous liquid material from the filling nozzle is stopped, and the container is carried out of the filling machine.

  In this method for producing a viscous liquid material in a container, since the viscous liquid material is discharged from the filling nozzle and the container is filled with the viscous liquid material, the viscous liquid material can be prevented from dripping. Thereby, it can suppress that a viscous liquid substance adheres to the outer side of a container, the conveyance path | route of a container, etc., and is contaminated. In addition, for example, when filling a liquid container in a tray-like container, products such as poor thermal welding at the time of container sealing or burnt kogation of the viscous liquid substance caused by the viscous liquid substance attached to the flange of the container Defects can be suppressed.

  According to the present invention, dripping of a viscous liquid such as cream cheese can be suppressed.

  Hereinafter, with reference to drawings, a suitable embodiment of a manufacturing method of a filling nozzle concerning the present invention and a viscous liquid material with a container is described in detail. In addition, the same code | symbol shall be attached | subjected to the same or equivalent part in drawing.

[Production equipment for viscous liquids in containers]
First, with reference to FIG. 1, the manufacturing apparatus 1 of the viscous liquid substance containing a container is demonstrated. As shown in FIG. 1, the container-containing viscous liquid manufacturing apparatus 1 is an apparatus that manufactures a container-containing viscous liquid 4 in which a container 2 is filled with a viscous liquid 3. The container 2 is a tray-like container that is formed in a rectangular shape and has a flange portion formed in the peripheral edge portion. However, the container 2 may be anything as long as it can be filled with the viscous liquid material 3. The viscous liquid material 3 is a highly viscous liquid material. The viscosity of the viscous liquid material 3 is, for example, 4000 to 20000 cP (centipoise). As the viscous liquid material 3, for example, cream cheese, jam, pasty nursing food, or the like is used. The manufacturing apparatus 1 includes a transport device 5, a filling machine 6, and a sealing device 7.

  The transport device 5 is a device that transports the container 2 intermittently with a certain interval. The transport device 5 carries the container 2 into the filling machine 6 and carries the container 2 out of the filling machine 6. Further, the transport device 5 carries the container 2 into the sealing device 7 and carries the container 2 out of the sealing device 7. As the transport device 5, for example, a belt conveyor can be used.

  The filling machine 6 is an apparatus for filling the container 2 conveyed by the conveying device 5 with the viscous liquid material 3 by discharging the viscous liquid material 3 in a fixed amount. The filling machine 6 is charged with the viscous liquid material 3 and temporarily stores the viscous liquid material 3, the metering pump 12 that sends out the fixed amount of viscous liquid material 3, and the viscous liquid material sent out by the metering pump 12. 3 and a liquid feed pipe 14 that communicates the hopper 11 and the metering pump 12 and communicates the metering pump 12 and the filling nozzle 13. The metering pump 12 discharges the viscous liquid material 3 in the liquid feeding pipe 14 from the filling nozzle 13 by changing the volume in the cylinder by the stroke of the piston. The filling nozzle 13 is detachably attached to the filling machine 6 at the outlet end of the liquid feeding pipe 14. For this reason, the filling machine 6 can replace the filling nozzle 13 in accordance with the type and viscosity of the viscous liquid material 3 to be discharged. However, the filling nozzle 13 may be detachably attached to the filling machine 6 or may be integrated with the filling machine 6.

  The sealing device 7 is a device that is disposed downstream of the filling machine 6 in the transport direction of the transport device 5 and seals the container 2 filled with the viscous liquid material 3. For example, the sealing device 7 seals the container 2 by thermally welding (heat-sealing) a sheet-like lid to the peripheral edge of the container 2.

[Filling nozzle of the first embodiment]
Next, the filling nozzle 13 of the first embodiment will be described in detail with reference to FIGS. As shown in FIGS. 2 to 4, the filling nozzle 13 includes a nozzle portion 21 and an attachment portion 22.

  The nozzle portion 21 is a main body portion of the filling nozzle 13 that discharges the viscous liquid material 3. The nozzle unit 21 includes a flow path 23 through which the viscous liquid material 3 flows, a supply port 24 to which the viscous liquid material 3 is supplied, and a discharge port 25 from which the viscous liquid material 3 is discharged.

  The flow path 23 is formed by the inner wall of the nozzle portion 21 (filling nozzle 13). The flow path 23 communicates with the liquid feeding pipe 14 of the filling machine 6 when the filling nozzle 13 is attached to the filling machine 6. The supply port 24 is an opening on one side of the flow path 23, and is an opening through which the viscous liquid material 3 is supplied from the filling machine 6. The supply port 24 is formed in a perfect circle shape. However, the shape of the supply port 24 is not particularly limited. The discharge port 25 is an opening on the other side of the flow path 23 and discharges the viscous liquid material 3 from the flow path 23. The discharge port 25 is formed in a deformed elliptical shape having a constriction 26 at the center. In other words, the discharge port 25 has a shape in which the central portion in the major axis direction of the ellipse is constricted, and a pair of perfect circle or ellipse discharge ports communicate with each other through the constriction 26 and become an integrated shape. Hereinafter, the deformed ellipse shape having the constriction 26 at the center is simply referred to as a deformed ellipse shape. The deformed elliptical shape is also called a gourd shape.

  The nozzle portion 21 is formed in a tubular shape, and the discharge port 25 is formed into a deformed ellipse by curving the tip portion of the nozzle portion 21 on the discharge port 25 side. From the viewpoint of suppressing the pressure loss of the flow path 23, the shape of the flow path 23 is preferably gradually changed from the supply port 24 side toward the discharge port 25.

  The attachment portion 22 is a portion attached to the filling machine 6. The attachment portion 22 extends in a flange shape (disc shape) from the nozzle portion 21, and the bolt hole 27 for bolting the attachment portion 22 to the filling machine 6, the packing groove 28, and the filling nozzle 13 in the rotation direction. An alignment key 29 that defines the attachment position is formed. However, the shape of the attachment portion 22, the packing groove 28, the alignment key 29, the attachment structure of the attachment portion 22 to the filling machine 6, etc. are not particularly limited.

[Method for producing viscous liquid in container]
Next, with reference to FIG. 1, the manufacturing method of the viscous liquid substance containing a container of this embodiment is demonstrated. As shown in FIG. 1, the manufacturing apparatus 1 mentioned above is used in the manufacturing method of the viscous liquid substance in a container of this embodiment.

  First, the empty container 2 is carried into the filling machine 6 by the transport device 5. And if the container 2 is conveyed below the filling nozzle 13, the conveyance of the container 2 by the conveying device 5 is stopped. Thereby, the state in which the container 2 is located below the filling nozzle 13 is maintained.

  Next, when the container 2 is positioned below the filling nozzle 13, the metering pump 12 is operated to discharge a certain amount of the viscous liquid material 3 from the filling nozzle 13, thereby supplying a certain amount of the viscous liquid material 3 to the container 2. Fill.

  Next, the discharge of the viscous liquid material 3 from the filling nozzle 13 is stopped by stopping the operation of the metering pump 12. Thereafter, the transport of the container 2 by the transport device 5 is restarted, the container 2 filled with the viscous liquid material 3 is unloaded from the filling machine 6, and the container 2 is further loaded into the sealing device 7. And if the container 2 is carried in to the sealing apparatus 7, conveyance of the container 2 by the conveying apparatus 5 will be stopped.

  Next, the container 2 is sealed by the sealing device 7. Thereby, the container-containing viscous liquid material 4 in which the container 2 is filled with the viscous liquid material 3 is completed. Thereafter, the conveyance of the container 2 by the conveyance device 5 is resumed, and the sealed container 2 is unloaded from the sealing device 7.

  Thus, in the filling nozzle 13 according to the present embodiment, the discharge port 25 has a deformed elliptical shape having the constriction 26 at the center. Therefore, when the discharge port 125 of the nozzle part 121 has a perfect circle shape like the filling nozzle 113 shown in FIG. 8, or the discharge port 225 of the nozzle part 221 has an elliptical shape like the filling nozzle 213 shown in FIG. Compared to a case, the central portion of the discharge port 25 can be brought closer to the inner wall of the filling nozzle 13. That is, the frictional force of the viscous liquid material 3 located at the center of the discharge port 25 with respect to the inner wall of the filling nozzle 13 is made closer to the frictional force of the viscous liquid material 3 located near the inner wall of the filling nozzle 13 with respect to the inner wall of the filling nozzle 13. be able to. Thereby, it can suppress that the viscous liquid material 3 leaks.

  By the way, when the discharge port has a perfect circle shape (see FIG. 8) or an elliptical shape (see FIG. 9), the viscous liquid material 3 filled in the container 2 is radiated from one point located on the center line of the discharge port. It spreads. And since the fluidity | liquidity of the viscous liquid material 3 is low, when filling the viscous liquid material 3 in the rectangular container 2, there exists a problem that the viscous liquid material 3 is hard to be filled at the four corners of the container 2. FIG. However, in this filling nozzle 13, since the discharge port 25 has a deformed elliptical shape having a constriction 26 at the center, a small amount of the viscous liquid 3 is discharged from the center of the discharge port 25, and the discharge port sandwiches the constriction 26. A large amount of viscous liquid material 3 is discharged from both ends of 25. As a result, the viscous liquid material 3 filled in the rectangular container 2 spreads radially from two points separated from each other. Therefore, even if the fluidity of the viscous liquid material 3 is low, the viscous liquid material 3 is formed at the four corners of the rectangular container 2. 3 is easily filled.

  Moreover, since the nozzle part 21 is formed in a tubular shape, the discharge port 25 can be formed into an arbitrary deformed ellipse by a simple method of curving the nozzle part 21.

  Moreover, in the manufacturing method of the viscous liquid substance in a container of this embodiment, since the viscous liquid substance 3 is discharged from the filling nozzle 13 and the container 2 is filled with the viscous liquid substance 3, the viscous liquid substance 3 drips. Can be suppressed. Thereby, it can suppress that the viscous liquid material 3 adheres to the outer side of the container 2, the conveyance path | route of the container 2, etc., and becomes dirty. Further, when the viscous liquid material 3 is filled in the tray-like container 2, it is caused by the viscous liquid material 3 adhering to the flange portion of the container 2, and the thermal welding failure or the viscous liquid material 3 is burned when the container 2 is sealed. Product defects such as koge can be suppressed.

[Filling nozzle of the second embodiment]
Next, with reference to FIGS. 5-7, the filling nozzle 13A of 2nd embodiment is demonstrated in detail. As shown in FIGS. 5 to 7, the filling nozzle 13 </ b> A includes a nozzle portion 21, an attachment portion 22, and a contact member 31.

  The contact member 31 is a member that is disposed in the flow path 23 at the front end 21 a of the nozzle portion 21 that is the front end of the filling nozzle 13 </ b> A and is in contact with the viscous liquid material 3 that flows through the flow path 23. The tip portion 21 a is an end portion of the nozzle portion 21 on the discharge port 25 side. The contact member 31 is disposed at a position passing through the constriction 26 when viewed from the discharge port 25 side, and divides the flow path 23.

  The contact member 31 is composed of a rod-shaped member. And the contact member 31 is attached to the inner wall of the nozzle part 21 (filling nozzle 13A) which forms the flow path 23. The contact member 31 is formed in the same shape as the constriction 26, and both ends thereof are attached to the inner wall of the nozzle portion 21, thereby dividing the flow path 23.

  The contact member 31 should just be arrange | positioned at least in part of the front-end | tip part 21a, and the position in the direction parallel to the flow path 23, a length, etc. are not specifically limited. For example, the contact member 31 may be disposed only at a part of the distal end portion 21a, may be disposed throughout the distal end portion 21a, or may be disposed at a position beyond the distal end portion 21a. . Further, the tip of the contact member 31 on the discharge port 25 side may be flush with the discharge port 25 or may be positioned in the vicinity of the discharge port 25.

  As described above, in the filling nozzle 13A of the present embodiment, the contact with the flow path 23 in the tip portion 21a of the nozzle portion 21 that is the tip portion of the fill nozzle 13A is brought into contact with the viscous liquid material 3 flowing through the flow path 23. A member 31 is disposed. Thereby, since the viscous liquid material 3 remaining in the filling nozzle 13A also contacts the contact member 31 at the tip 21a, it is possible to further prevent the viscous liquid material 3 from dripping.

  Further, since the contact member 31 is arranged at a position passing through the constriction 26 in the central portion when viewed from the discharge port 25 side and divides the flow path 23, the viscous liquid material 3 is formed at both ends of the discharge port 25 sandwiching the constriction 26. It is possible to equalize the influence of the acting frictional force and to prevent the liquid from dripping from one end.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment. For example, in the above embodiment, the nozzle portion has been described as having a tubular shape, but the nozzle portion may not be tubular as long as the discharge port of the flow path has a deformed elliptical shape. In the above embodiment, the filling nozzle is described as including an attachment portion. However, when the filling nozzle is integrated with the filling machine, the filling nozzle may not include the attachment portion.

  Examples of the present invention will be described below. However, the present invention is not limited to the following examples.

[Comparative Example 2]
As Comparative Example 2, a filling nozzle having an elliptical discharge outlet was produced. In the filling nozzle of Comparative Example 2, the tip of a circular tube having a length of 38 mm and an inner diameter of 24 mm was curved, and the discharge port was formed into an elliptical shape having a major axis of 28 mm and a minor axis of 16 mm (see FIG. 9).

[Example 1]
As Example 1, a filling nozzle in which the discharge port has a deformed elliptical shape was produced.

[Example 2]
As Example 2, a filling nozzle was produced in which the discharge port had a deformed elliptical shape and a stainless steel contact member was disposed in the flow path. In the filling nozzle of Example 2, first, a filling nozzle having a discharge ellipse having a deformed elliptical shape is produced in the same manner as in Example 1. Next, a width W2 as a contact member is formed in the flow path at the tip of the filling nozzle. An 8 mm stainless steel piece was attached (see FIGS. 5 to 7). At this time, this stainless steel piece was disposed at a position passing through the constriction when viewed from the discharge port side, the flow path was divided by this stainless steel piece, and the width W3 of the flow path divided by the stainless steel piece was 10 mm. The concrete drawing of the filling nozzle of Example 2 is shown in FIGS. 10-20 and FIGS. 21-31. 10 to 20, the characteristic part including the stainless steel piece is indicated by a solid line, the other part is indicated by a broken line, and the boundary between the characteristic part and the other part is indicated by a one-dot chain line. ing.

In FIG. 31, the thin line represented on the surface portion of the filling nozzle is for specifying the shape of the three-dimensional surface.

[Evaluation]
After filling cream cheese into a container using the filling nozzles of Comparative Examples 1 and 2 and Examples 1 and 2, the filling operation was stopped and the occurrence of dripping from the filling nozzle was observed. For the filling of the cream cheese, a servo-driven quantitative filling machine FX-01 (filling capacity: 1500 pieces / h) manufactured by Shikoku Kako Co., Ltd. was used. And the cream cheese of the viscosity range of 4000-20000 cP was heated at 70 degreeC or more, and 50g was filled per container.

  In Comparative Examples 1 and 2, the cream cheese remaining in the filling nozzle drastically spilled from the center of the discharge port immediately after the filling pause. At this time, no dripping occurred near the inner wall of the filling nozzle.

  On the other hand, in Example 1, the liquid dripping until 15 seconds passed after the filling stop was small, and the liquid dripping was significantly improved as compared with Comparative Examples 1 and 2. Further, in Example 2, no dripping occurred even after 15 seconds from the filling pause.

  The dripping occurred when the gravity applied to the cream cheese remaining in the filling nozzle became larger than the frictional force between the cream cheese and the inner wall of the filling nozzle or the shearing force between the cream cheese. As a result, dripping is suppressed by bringing the friction force of cream cheese located in the center of the discharge port against the inner wall of the filling nozzle closer to the friction force of cream cheese located near the inner wall of the filling nozzle against the inner wall of the filling nozzle. Furthermore, it was found that the dripping disappeared.
