Description

  The present invention relates to an extruder for placing a fluid food such as soft cream in a container.

  Conventionally, as a device for placing soft ice cream in a container, a liquid food material enclosure containing frozen soft ice cream ingredients for one serving is placed on a cradle and pressed to open the soft ice cream from a hole opened downward. Extruders that extrude and deposit in containers are known (for example, Patent Documents 1 and 2). According to this extruder, since the ingredients of the fluid food enclosure divided into small portions are used up each time, hygiene management such as equipment cleaning is easier than equipment that continuously produces soft ice cream. It has the advantage of reducing waste. In addition, the structure is relatively simple and the installation cost is low.

  However, when placing the fluid food enclosure containing the frozen soft ice cream ingredients on the cradle or removing the fluid food enclosure after the extrusion, the extrusion piston of the extruder It is necessary to widen the gap with the cradle to some extent. For this reason, the movable range of the extrusion piston of the extruder becomes long, and as a result, the height of the extruder becomes high, and there is a possibility that securing the installation space becomes difficult.

  In response to these problems, extruders that can move the cradle in the horizontal direction have been developed (Patent Documents 3 to 5). According to these extruders, it is not necessary to lengthen the movable range of the extrusion piston. A work space for placing and removing the pack can be secured.

Japanese Patent Laid-Open No. 2006-63751 JP 2003-250457 A JP-A-7-227214 JP 2000-232285 A JP 2000-236815 A

  However, in the extruder that moves the conventional cradle in the horizontal direction, after the cradle is horizontally moved and the fluid food material enclosure is placed, it is necessary to return the cradle to the original position again manually or by a drive mechanism. there were. For this reason, the operation from placing the fluid food material enclosure to pressing with the pressing mechanism is complicated, requires skill, and takes time.

  The present invention has been made to solve the above-described conventional problems, and the horizontally moved cradle can be automatically returned to the original position, after the fluid food material enclosure is placed. It is an object to be solved to provide an extruder that is easy to operate until it is pressed by a pressing mechanism and that can shorten the manufacturing time.

The extruder according to the present invention compresses a cradle provided so as to be rotatable about the axis of a support column provided on a base and a fluid food material enclosure placed on the cradle, thereby supplying a fluid food material. In an extruder equipped with a pressing mechanism for extruding downward,
A cylindrical stopper for preventing the cradle from falling is fixed to the support column by being inserted into the support column, and a spiral stopper inclined surface is formed at the upper end of the stopper and is notched. A stopper recess is formed around the column,
At the lower end of the cradle, a spiral pedestal inclined surface that is in close contact with the stopper inclined surface, and a pedestal convex portion that fits with the stopper concave portion with a gap are formed around the support column. ,
When the pedestal inclined surface descends while sliding on the stopper inclined surface by a predetermined distance, the pedestal convex portion comes into contact with the side wall of the stopper concave portion to prevent the sliding down. .

  In the extruder according to the present invention, since the cradle can be rotated around the axis of the column erected on the base, when the fluid food material enclosure is placed on the cradle, the work above the cradle Since a large space can be taken, the work can be easily and quickly performed. In addition, when returning the cradle to the base position with the fluid food enclosure placed on the cradle, when the cradle inclined surface is lowered while sliding the stopper inclined surface by a predetermined distance, The sliding is prevented by coming into contact with the side wall of the stopper recess. For this reason, the horizontally moved cradle can be automatically returned to the original position, and the operation from the placement of the fluid food enclosure to the pressing by the pressing mechanism is easy and the manufacturing time is shortened. Can do.

Further, in the extruder of the present invention, when the pedestal inclined surface rises while sliding the stopper inclined surface by a predetermined distance, the pedestal convex portion comes into contact with the side wall of the stopper concave portion to prevent the sliding down. Preferably it is.
In this case, in order to place the fluid food material enclosure on the cradle, when the operator pivots the cradle around the axis of the column erected on the base, it always has a predetermined rotation. It can be stopped at an angle. For this reason, the angle of rotation of the cradle changes every time work is performed, so that the angle of rotation of the cradle becomes too large and interferes with the surroundings, or conversely, the angle of rotation of the cradle is too small. When the fluid food material enclosure is placed on the cradle, it is possible to prevent the pressing piston from interfering with it.

  Moreover, in the extruder of this invention, it is preferable that a stopper horizontal surface is continuously extended from the highest position of the said stopper inclined surface, and is formed around this support | pillar. If this is the case, since the cradle does not automatically slide down the stopper inclined surface, it is possible to perform the work of placing the fluid food enclosure on the cradle while the cradle is held in a stable position. .

  Furthermore, in the extruder of the present invention, it is preferable that a solid lubricating layer is formed on the stopper inclined surface and / or the pedestal inclined surface. In this case, the friction between the stopper inclined surface and the pedestal inclined surface is reduced, and the pedestal can be rotated with a small force.

(Example 1)
FIG. 1 is a perspective view of an extruder 1 of Example 1, which is for extruding soft ice cream from an ice raw material enclosure containing a frozen ice cream for one serving. The extruder 1 is provided with a base 2 made up of a substantially rectangular frame and a support column 3 standing upright from the center of the rear end of the base 2 to push soft cream onto the upper end of the support column 3. An extrusion mechanism 4 is provided.

  As shown in FIG. 2, a bracket 5 is provided in the push-out mechanism 4, and a rack 6 and a pinion 7 are provided in the bracket 5 so as to mesh with each other as shown in FIG. 3. The pinion 7 is pivotally supported by a shaft 8. As shown in FIG. 2, the shaft 8 protrudes from the bracket 5, and a lever 9 is attached to the protruding portion. A cylindrical pressing piston 10 is attached to the lower end of the rack 6. Further, as shown in FIG. 3, a spring 11 is housed in the bracket 5, and one end of the center of the spring 11 is fixed to the shaft 8, and the lever 9 lowered downward is automatically moved upward. An urging force to return to is generated.

  In addition, as shown in FIG. 1, a cradle 12 is provided at the center portion of the column 3. A hole 15 through which the column 3 is inserted is formed at the rear end of the cradle 12, and the cradle 12 can be rotated around the axis of the column 3 (see FIG. 4). A receiving member 14 is fitted in the front portion of the cradle 12 to place the ice material enclosure. As shown in FIG. 5, the ice raw material enclosure 100 has a structure in which a polyethylene enclosure body 102 surrounding a frozen ice raw material 101 is held in a bottomless substantially cylindrical tubular enclosure holding cup 103. A recess 103 a that opens downward is provided on the periphery of the enclosure holding cup 103. The recess 103a can be fitted to the peripheral edge 14a of the receiving member 14 (see FIG. 1). As shown in FIG. 6, a star-shaped discharge hole 104 for discharging the extruded ice is formed in the center of the back side of the enclosure holding cup 103, and an adhesive tape 105 is attached so as to close the discharge hole 104. It is pasted.

As shown in FIG. 1, the cradle 12 is prevented from dropping by a cylindrical stopper 13 that is inserted into the column 3 and fastened with screws.
As shown in FIG. 7, the outer diameter of the stopper 13 is reduced upward, and the upper end thereof is a spiral stopper inclined surface 13a and a stopper erected adjacent to the lowest position of the stopper inclined surface 13a. A convex portion 13b and a horizontal surface 13c that continues smoothly from the highest position of the stopper inclined surface 13a are formed so as to surround the support 13. Further, a stopper recess 13d is provided adjacent to the stopper protrusion 13b, and a stopper horizontal portion 13e having a horizontal upper surface adjacent to the stopper recess 13d is formed so as to surround the support 13.

  Further, on the lower side of the cradle 12, a spiral cradle inclined surface 12a closely contacting the stopper inclined surface 13a, a cradle recess 12b fitted to the stopper convex portion 13b, and a receiver fitted with a gap in the stopper concave portion 13d. The base convex part 12d and the cradle horizontal part 12e which contact | connects the stopper horizontal part 13e are provided. The stopper recess 13d is formed with an angle from the axis of 135 °, whereas the cradle protrusion 12d fitted into the stopper recess 13d is formed with an angle of 90 ° from the axis. . Then, when the pedestal inclined surface 12a slides down the stopper inclined surface 13a and the pedestal 12 rotates 45 °, the side wall of the pedestal convex portion 12d collides with the side wall of the stopper concave portion 13d, and the rotation stops. It is supposed to be.

<How to use>
When soft ice cream is manufactured using the extruder 1 of Example 1 configured as described above, first, the right side of the cradle 12 of the extruder 1 shown in FIG. 1 is pushed leftward by hand. As a result, the cradle 12 rotates about the axis of the shaft 3 (see FIG. 4), and as shown in FIG. 8A, the cradle inclined surface 12a and the stopper inclined surface 13a are in close contact with each other. The pedestal inclined surface 12a is slid up from the state where it is in contact with the stopper inclined surface 13a, and reaches the stopper horizontal surface 13c (see FIG. 8B). Then, when the cradle 12 is further rotated by 45 ° around the axis of the support column 3, the side wall of the cradle convex portion 12d shown in FIG. 7 collides with the side wall of the stopper concave portion 13d, preventing further rotation. Is done. As a result, as shown in FIG. 4, the pressing piston 10 does not exist above the cradle 12.

  In this state, since the lower end of the cradle inclined surface 12a gets over the stopper inclined surface 13a and is in contact with the stopper horizontal surface 13c, the cradle 12 does not automatically slide down the stopper inclined surface 13a. For this reason, even if the hand is moved away from the cradle 12, the cradle 12 remains metastable at a position rotated by 45 ° around the axis of the column 3.

  Next, the operator takes out the ice raw material enclosure 100 shown in FIG. 5 from the freezer, peels off the adhesive tape 105 at the lower end of the ice raw material enclosure 100, and forms a recess 103 a provided on the periphery of the enclosure holding cup 103. Are fitted to the peripheral edge 14a of the receiving member 14 shown in FIG. Then, the left side of the cradle 12 is pushed rightward by hand. As a result, as shown in FIG. 8, the cradle 12 rotates, and the lower end of the cradle inclined surface 12a slides on the stopper horizontal surface 13c, and further slides down the stopper inclined surface 13a, from the state shown in FIG. 8B. 8 at the time when the state shown in FIG. 8A is reached (that is, when the cradle 12 rotates 45 ° around the axis of the column 3 and returns to the original position). The side wall of 12d collides with the side wall of the stopper recess 13d, and further rotation is prevented. As a result, as shown in FIG. 1, the pressing piston 10 exists above the cradle 12.

  In this state, the handle 9 is gradually pushed down by hand. As a result, the pinion 7 shown in FIG. 3 rotates together with the shaft 8, the rack 6 moves down together with the pressing piston 10, and the lower end of the pressing piston 10 comes into contact with the ice material enclosure 100 and further presses. As a result of the ice material envelope 100 being pressed, soft ice cream having a star-shaped cross section is pushed out from the discharge hole 104. The extruded soft serve is received in a container such as a corn cup. When the soft ice cream is pushed out from the ice raw material enclosure 100, the shaft 8 rotates together with the pinion 7 by the restoring force of the mainspring spring 11 shown in FIG. At the same time, the lever 9 automatically returns to the original position.

As described above, in the extruder according to the first embodiment, since the cradle 12 can be rotated around the axis of the support column 3, when the fluid food material enclosure 100 is placed on the cradle 12, The work space above the table 12 can be widened. For this reason, work can be performed easily and quickly. Further, when the cradle 12 is returned to the original position with the fluid food material enclosure 100 placed on the cradle 12, when the cradle inclined surface 12a is lowered while sliding the stopper inclined surface 13a by a predetermined distance, Since the cradle convex portion 12d is in contact with the side wall of the stopper concave portion 13d to prevent the sliding, the horizontally moved cradle 12 can be automatically returned to the original position. For this reason, the operation from the placement of the fluid food enclosure 100 to the pressing by the pressing mechanism 4 is easy and the manufacturing time can be shortened.
Further, when the pedestal inclined surface 12a rises while sliding on the stopper inclined surface 13a by a predetermined distance, the pedestal convex portion 12d abuts against the side wall of the stopper concave portion 13d to prevent the sliding, so that the fluid food enclosure When the operator rotates the cradle 12 around the axis of the support column 3 in order to place 100 on the cradle 12, it can always be stopped at a predetermined rotation angle. For this reason, the rotation angle of the cradle 12 does not change every time the work is performed, and the rotation angle of the cradle 12 becomes too large and interferes with the surroundings. It is too small and it can prevent that the press piston 10 interferes and becomes obstructive when mounting the fluid food material enclosure 100 on the cradle 12.

(Modification of Example 1)
In the extruder of Example 1, a solid lubricant layer can also be formed on the stopper inclined surface 13a and / or the pedestal inclined surface 12a. In this case, the friction between the stopper inclined surface 13a and the pedestal inclined surface 12a is reduced, and the rotating operation of the pedestal 12 can be performed with a small force. In order to form the solid lubricant layer, a thin plate made of a solid lubricant or a thin plate containing a solid lubricant is attached to the stopper inclined surface 13a and / or the pedestal inclined surface 12a, or a solid lubricant is applied. Is mentioned. Examples of the plate made of a solid lubricant include a fluororesin plate, a nylon plate, a polyethylene plate, and a polypropylene plate. Examples of the method of applying the solid lubricant include a method of applying graphite powder, molybdenum disulfide powder, or fluororesin powder to the surfaces of the stopper inclined surface 13a and / or the pedestal inclined surface 12a.
