Description

  The present invention relates to a liquid food filling nozzle.

  Conventionally, a filling nozzle for filling a liquid food into a container is known (see, for example, Patent Document 1 and Patent Document 2).

JP 58-30903 A JP2015-168475A

  With conventional filling nozzles such as those described in Patent Document 1 and Patent Document 2, when filling a container with fluid food, particularly fluid food having a viscosity of 40 poise to 1500 poise, the fluid food is separated from the filling nozzle. Therefore, the so-called stringing is likely to occur, and the liquid food may adhere to the outside of the container and the container may become dirty.

  The objective of this invention is providing the filling nozzle which can suppress the stringing of the fluid food at the time of filling a container.

  The filling nozzle of the present invention is a filling nozzle that is detachably provided in a filling port that fills a container with liquid food, and is connected to the storage part capable of storing the liquid food, the storage part, and the storage part And a plurality of discharge ports penetrating the filling nozzle, and the length of the discharge port is set to be longer than one half of the depth dimension of the storage portion.

  According to the present invention, since the length of the discharge port is set to be longer than one half of the depth dimension of the storage portion, the liquid food does not stay excessively in the storage portion, and from the storage portion. Since the distance to the outlet outlet becomes longer and the liquid food in the reservoir does not easily flow out through the outlet, the filling nozzle can be quickly separated from the liquid food filled in the container, and the container is filled. The stringing of the liquid food at the time can be suppressed.

  In the filling nozzle of the present invention, it is preferable that the discharge ports are arranged radially.

  According to the present invention, since the discharge ports are arranged radially, the liquid food can be distributed to the corners in the container, and the liquid food can be evenly filled in the container.

  In the filling nozzle of the present invention, it is preferable that the discharge ports are arranged in parallel in the radial direction.

  According to the present invention, since the discharge ports are arranged in the radial direction, the diameter of each discharge port can be reduced, and when filling liquid food, particularly liquid food having a viscosity of 40 poise to 1500 poise. In addition, it is possible to more reliably suppress stringing that occurs near the discharge port.

  In the filling nozzle of the present invention, it is preferable that the discharge port has an oval shape.

  According to the present invention, since the discharge port has an oval shape, the cross-sectional area of the discharge port can be partially increased. For this reason, even when the non-fluid food is mixed with the liquid food, it is possible to prevent the discharge port from being clogged while suppressing stringing of the liquid food.

  The filling nozzle of the present invention is preferably used for a liquid food having a viscosity of 40 poise to 1500 poise.

In the second and subsequent embodiments, the same constituent members as those in the first embodiment and constituent members having the same functions are denoted by the same reference numerals as those in the first embodiment, and the description thereof is omitted or simplified. To do.

[First Embodiment]
In FIG. 1, a filling machine 1 fills a container 90 with a predetermined amount of melted cheese (hereinafter referred to as “molten cheese”) as a liquid food. In addition, although the structure of the filling machine 1 describes the structure of a general cheese filling machine, this invention is related to the filling nozzle and does not specifically limit the structure itself of the filling machine.
The container 90 is formed in a substantially circular shape in plan view and is conveyed below the filling machine 1 by a conveying device 80 such as a belt conveyor. Moreover, although melted cheese is mentioned as an example and demonstrated as a fluid food, it does not specifically limit to this.

  In FIG. 1, the filling machine 1 includes a hopper 2, a filling mechanism 3, and a filling nozzle 4.

  The hopper 2 includes a storage portion 21 having a storage space 21A for storing molten cheese, and an outflow path 22 that is provided at the lower end of the storage portion 21 and from which the molten cheese flows out.

The filling mechanism 3 includes a piston 31 provided in the outflow path 22 of the hopper 2 so as to be movable forward and backward, a drive device 32 for driving the piston 31, and a rod 34 provided with a communication path 33 communicating with the outflow path 22 therein. And a block 35 provided at the tip of the rod 34 and a drive device (not shown) for driving the rod 34.
The communication path 33 extends from the rod 34 into the block 35, and forms a filling port 33 </ b> A for filling the container 90 with molten cheese at the opening.
The block 35 includes a block main body 36 provided at the distal end portion of the rod 34 and an attachment portion 37 for detachably attaching the filling nozzle 4 to the filling port 33A.
The attachment portion 37 includes a recess 37A provided on one surface, and a through hole 37B penetrating the attachment portion 37 from the recess 37A toward the other surface of the attachment portion 37. The attachment portion 37 is fixed to the block body 36 by bolts 38.

  2 to 4, the filling nozzle 4 is provided on the base portion 41, the flange portion 42 provided on the end portion of the main body portion 41, and the base end surface 41 </ b> A on the flange portion 42 side of the main body portion 41. A storage section 43 that can be stored, and a plurality of discharge ports 44 that communicate with the storage section 43 and penetrate the filling nozzle 4 from the storage section 43, the entirety of which is integrated with a heat-resistant resin such as Teflon (registered trademark). Molded. As for the filling nozzle 4, the main-body part 41 is penetrated by the through-hole 37B of the attaching part 37, and it is latched by the recessed part 37A of the attaching part 37 with the flange part 42 (refer FIG. 1).

  The main body portion 41 includes a protruding portion 41C that protrudes from the side surface 41B. The main body 41 has an outer shape in which one side surface 41B of a vertically long rectangular parallelepiped protrudes in the length direction by the protruding portion 41C, in other words, an outer edge shape in which one side of a quadrangle protrudes outward in plan view.

  The flange portion 42 extends from the peripheral edge of the main body portion 41 in a direction parallel to the base end surface 41 </ b> A, and is provided continuously along the peripheral edge portion of the main body portion 41.

  The storage part 43 has a substantially triangular shape in plan view, and one apex P thereof is disposed on the protruding part 41C. In the case of this embodiment, the storage part 43 has a depth dimension D reaching from the base end face 41A to the vicinity of the end face (lower end face) 42A opposite to the base end face 41A of the flange part 42.

  The discharge ports 44 are arranged at each of the three corners of the storage portion 43, extend in parallel with each other, and open at the distal end surface 41 </ b> D of the main body portion 41. The discharge port 44 has an oval shape in plan view, and its long axis is directed from the predetermined positions C1 and C2 of the main body portion 41 to each vertex P of the storage portion 43 as shown by a one-dot chain line in FIG. Radially arranged, that is, the three discharge ports 44 are arranged radially with respect to the predetermined positions C1 and C2. If the non-fluid food is mixed with the molten cheese, for example, the length of the major axis of the discharge port 44 may be set as appropriate according to the size of the non-fluid food. The length L of the discharge port 44 is set to be longer than one half of the depth dimension D of the storage portion 43. The predetermined positions C1 and C2 are positions of the base end surface 41A and the front end surface 41D of the main body 41, and are in the same position in plan view.

  When the container 90 is filled with molten cheese by the filling machine 1 shown in FIG. 1, the piston 31 is driven by the driving device 32, and the molten cheese that has flowed out of the accommodation space 21 </ b> A in the hopper 2 to the outflow path 22 is moved by the piston 31. Push into the communication path 33. Thereby, molten cheese is sent to the storage part 43 from the communicating path 33 through the filling port 33A. Further, the rod 34 is driven by a driving device (not shown), and the filling nozzle 4 is lowered. As a result, while the filling nozzle 4 is close to the container 90, the molten cheese in the storage portion 43 is discharged from the discharge port 44 and filled into the container 90. Thereafter, the filling nozzle 4 also rises as the rod 34 rises, whereby the molten cheese in the container 90 is separated from the filling nozzle 4 and the filling of the molten cheese into the container 90 is completed.

As shown in FIG. 5, the conventional filling nozzle has a deep reservoir 45 and a shallow outlet 46. In the case of such a filling nozzle, at the time of filling, after the filling nozzle is lowered and stored in the storage unit 45 and the molten cheese is discharged into the container 90, the molten cheese is excessively discharged from the discharge port 46 as the filling nozzle is raised. As a result, the melted cheese was stringed.
Therefore, it is considered that the cause of this stringing is that the molten cheese is excessively retained in the storage portion 45, and the depth dimension D of the storage portion 45 is shortened and the length L of the discharge port 46 is lengthened. When the stringing was verified, as shown in FIG. 3 (and FIG. 7), the length L of the discharge port 44 was made longer than one half of the depth dimension D of the storage portion 43, so It has been found that the stringing of cheese can be reduced and the filling nozzle 4 can be quickly separated from the cheese filled in the container 90. In particular, when filling a liquid food having a viscosity of 40 poise to 1500 poise, the effect was remarkable.

  By setting the length L of the discharge port 46 to be longer than one half of the depth dimension D of the storage unit 45, the distance from the storage unit 45 to the outlet of the discharge port 46 is increased, It becomes difficult for the liquid food to flow out through the discharge port 46, the filling nozzle 4 can be quickly separated from the molten cheese filled in the container 90, and stringing of the molten cheese when filling the container 90 is suppressed. Can do.

  In addition, since the discharge ports 46 are arranged radially, the molten cheese can be spread over the corners in the container 90, and the molten cheese can be evenly filled in the container 90.

  Further, since the discharge port 46 has an oval shape, the cross-sectional area of the discharge port 46 can be partially increased. For this reason, even when the non-fluid food is mixed with the molten cheese, it is possible to prevent the discharge port 46 from being clogged while suppressing stringing of the molten cheese.

[Second Embodiment]
As shown in FIGS. 6 to 8, the filling nozzle 4 </ b> A of the present embodiment is provided with a protrusion 41 </ b> E protruding in the out-of-plane direction from the tip surface 41 </ b> D of the main body 41 and the shape and number of the discharge ports 44 </ b> A. This is different from the first embodiment. Moreover, it differs from 1st Embodiment by the point provided with the discharge outlet 44B.

The protrusions 41 </ b> E extend on the tip surface 41 </ b> D of the main body 41 in the direction from the predetermined position C <b> 2 toward the three apexes P of the storage unit 43.
The discharge ports 44A have a perfect circle shape in plan view, and are arranged in parallel in two radial directions from the predetermined positions C1 and C2. The discharge port 44A extends from the storage portion 45 to the ridge portion 41E and opens at the ridge portion 41E.
The discharge port 44B is disposed at a position on the main body 41 opposite to the protruding portion 41C, and is open at a position surrounded by the protrusion 41E on the tip surface 41D of the main body 41.

  According to the present embodiment, since the discharge ports 44A are arranged in the radial direction, the diameter of each discharge port 44A can be reduced, and stringing of molten cheese can be more reliably suppressed.
