Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a filling nozzle device for discharging viscous and relatively fluid foods, such as pickled yam juice. It is used in the field of food manufacturing, where the above foods are quantitatively filled into containers or outer food products.

[Conventional technology]

Conventionally, in filling this type of viscous food, it has been an important issue to prevent the food remaining attached to the mouth end of the nozzle from dripping after the fixed amount has been discharged.

In order to solve this problem, for example,
As in No. 24057, a rotary valve body having a through hole and a closing plate protruding near the nozzle body is rotatably mounted inside the nozzle body, and the rotary valve body rotates to close the through hole. When the nozzle communicates with the discharge hole of the nozzle body, the food is discharged, and when the nozzle communicates with the discharge hole, the discharge is stopped, and the closing plate abuts against the wall surface of the discharge hole to prevent residual food from dripping. What is on offer.

In addition, as in Utility Model Publication No. 58-25826, an extrusion piston that moves up and down is inserted into the nozzle cylinder, and the food is forced into the nozzle cylinder from the quantitative pressure feeding part, and a predetermined amount is discharged from the mouth end of the nozzle cylinder. There is also a known configuration in which the extrusion piston is then lowered to extrude the food remaining stuck inside the cylinder.

[Problems that this invention attempts to solve]

In all of the conventional devices mentioned above, the tip opening of the nozzle is hollow and cylindrical, and this tip opening is closed with an extrusion piston or a closing plate, so any food remaining in the opening is removed at once. It is cut and pushed out. Moreover, the adhesion area of the food pushed out to the outside of the closed part is extremely small, so if the food is viscous but has relatively high fluidity, it will stick until the next container is transferred to the predetermined position. It had the disadvantage that it could not stay in place and immediately dripped down.

[Means for solving problems]

This proposal attempts to solve the above problems, and has a truncated conical shape at the lower end of the guide tube and the central rod, which has multiple grooves in the axial direction in the upper half and extends to the lower half. An adjustment shaft which is fitted into the nozzle cylinder with a guide member attached thereto, and which is tightened by a bolt screwed into the nozzle cylinder to form an annular discharge port at the bottom of the nozzle cylinder by tightening the side surface of an arbitrary partition wall between the concave grooves; and a slide member having a plurality of recesses at the edge of a thin lower opening through which the nozzle tube is inserted into a through hole extending vertically through the part, and the slide member is raised and lowered at a predetermined timing to open and close the annular discharge port. The main point is the structure that allows

[Effect]

For convenience of explanation, the operation of the present device having the above configuration will be explained with reference to the reference numerals attached to the drawings of the embodiments.

In the state shown in FIG. 1 in which the transferred container (dotted chain line in FIG. 1) is stopped at a position directly below the nozzle tube 3, the slide member 11 rises and is moved between the lower end of the nozzle tube 3 and the guiding member 7. An annular outlet c formed in
is opened and the food that is fed under pressure from the quantitative pressure feeding section 1 is
Channel space a of each concave groove 6 of adjustment shaft 5, central shaft rod 5c
, and is radially discharged from the annular discharge port c along the inclined descending surface 7a of the guiding member 7.

At this time, the width m of the annular discharge port c can be freely set by moving the mounting position of the adjustment shaft 5 up and down in advance according to the type of food to be filled, the amount of filling, etc.

When a certain amount of food is discharged, the lifting device 16 is activated, and the arm 17 lowers the slide member 11 to a predetermined position as shown in FIG.
The annular outlet c is closed by the inner wall surface of the annular outlet c.

In this case, food adheres and remains on the inclined descending surface 7a of the guide member 7 and the vertical peripheral wall surface 7b continuous thereto, but the food is radially scattered and discharged by the guide member 7 as described above. Therefore, the remaining amount is small and the layer is thin at all positions of the portion, and furthermore, the edge of the tip opening 13 of the slide member 11 is corrugated by the recess 14, so that there is no adhering food. The food is not cut and pushed out all at once, but each of the recesses 14 comes into contact with the upper end of the peripheral wall surface 7b at different times and cuts the food by a sliding action. A large amount of food will not adhere to the inner wall surface of the through hole 12.

Note that a small amount of food adheres to the inner wall surface of the through hole 12, but since the adhesion space is wide, it can sufficiently remain until the next container is transferred, and the edge of the opening 13 It will not drip immediately.

When the slide member 11 that has descended as described above is moved to a predetermined position and stopped, the slide member 11 rises and returns to the previous position, and the annular discharge port c is opened.
Repeat the above operations.
