Description

Ice machine

The present invention relates to an ice cutting machine for cutting by cutting block-shaped ice on a cutting table on which a cutting blade is attached.

Conventionally, an ice shaving machine as shown in FIG. 10 is known (Patent Document 1). In this ice cutting machine, a cutting blade 91a is attached to a cutting table 91, and an ice presser 93 for pressing the ice 92 from above is provided above the cutting table 91. Further, a rotating mechanism 94 that rotates the ice retainer 93 by a motor (not shown) and a lifting mechanism 95 that moves the ice retainer 93 up and down by rotating the handle 95a by hand are provided.

When cutting block-shaped ice with this ice cutter, first, the handle 95a of the elevating mechanism 95 is rotated by hand to raise the ice presser 93. Then, the ice 92 is placed on the cutting table 91, the handle 95 a of the lifting mechanism 95 is rotated again in the reverse direction to rotate the ice presser 93, and the ice 92 is held by the pick 93 a of the ice presser 93. Further, the rotation mechanism 94 is driven to rotate the ice retainer 93 fixed to the tip of the rotation shaft 97. Thus, the ice 92 is cut by the cutting blade 91a, and the ice powder is discharged downward.

However, in the above-mentioned conventional ice scraper, when the position of the center of gravity of ice deviates from the position of the axis of the rotation axis of the ice presser 93, large and heavy ice rotates eccentrically. For this reason, there was a risk that the ice-shaving machine would vibrate or rattle. In order to prevent such problems, when placing the ice on the cutting table, the operator must carefully check the position of the ice from the front, back, left, and right so that the center of gravity of the ice matches the position of the axis of the rotating shaft. It was necessary to put it on, and it took time and effort.

The present invention has been made to solve the above-described conventional problems, and when placing ice on a cutting table, it is easy to match the position of the center of gravity of the ice with the position of the axis of the rotating shaft. It is an object to be solved to provide an ice shaving machine that is less likely to vibrate or rattle.

The ice cutting machine of the present invention has a slit, a cutting table attached so that a cutting blade protrudes from the slit, an ice presser for pressing ice placed on the cutting table from above, and the ice presser In an ice cutting machine provided with a rotation mechanism for rotating the ice presser and an elevating mechanism for raising and lowering the ice presser, the cutting table gradually becomes deeper in the axial direction of the rotation shaft of the ice presser The ice holder is attached with an ice guide member having a common axis with the ice holder rotation shaft and expanding downward from the ice holder in a tapered shape. The ice guide member guides the ice in the axial direction when the ice presser is lowered.

In order to cut ice with the ice cutting machine of the present invention, first, the lifting mechanism is driven to raise the ice presser, and a space for placing ice on the cutting table is secured. Then, after placing ice on the cutting table, the lifting mechanism is driven in reverse to lower the ice presser. Thereby, an ice guide part contacts the upper end of ice. Here, since the ice guide portion has a common axis with the rotation axis of the ice presser and expands in a tapered shape downward from the ice presser, the ice contacting the ice guide portion is the center of the ice. Even if it is deviated from the axis of the rotation axis of the ice presser, the ice guide part is further lowered to receive the force in the radial direction and is automatically guided in the axial direction. Furthermore, since the cutting table is gradually deepened toward the axis of the rotation axis of the ice presser, if the bottom surface of the ice is a flat surface, the portion where the cutting blade contacts the ice is the corner of the bottom surface. Point contact of only the part. For this reason, when the ice guide unit guides the ice in the axial direction, the ice is smoothly guided without being caught by the cutting blade. The ice melt is fixed by the ice presser, and rotates together with the ice presser by driving the rotation mechanism to rotate the ice presser. At this time, since the position of the center of gravity of the ice has already been automatically guided to the position of the axis of the rotating shaft by the ice guiding portion, there is little possibility that the ice shaving machine will vibrate or rattle.

The inclination angle formed with the horizontal surface of the taper-shaped portion of the ice guide member is preferably 10 ° to 45 °. If the inclination angle is less than 10 °, the force for guiding ice in the axial direction becomes weak, and smooth ice guidance becomes difficult. In addition, if the inclination angle exceeds 45 °, the difference in height of the taper part becomes large, and even when ice cutting progresses and the lower end of the taper part is in contact with the cutting table, a lot of ice remains, which is effective for ice. The utilization rate decreases and the yield deteriorates. More preferred is 15 ° to 40 °, and most preferred is 20 ° to 35 °.
The inclination angle of the cutting table in the axial direction is preferably 5 ° to 15 °. When the inclination angle is less than 5 °, when the bottom surface of the ice is uneven, the ice is easily caught by the cutting blade when the ice is guided in the axial direction by the ice guiding member. On the other hand, if the tilt angle exceeds 15 °, the volume of ice remaining in the inverted conical shape is increased in the state where the cutting of the ice is finished, resulting in poor yield.

It is preferable that the ice guide member is attached to the ice presser so as to be movable up and down by the biasing force of the elastic member. In this case, the ice presser can be further lowered after the ice cutting progresses and the lower end of the ice guide portion hits the cutting table. For this reason, the yield for cutting ice can be improved.

It is also preferable that the ice guide member is slidably inserted into an auxiliary member provided so as to protrude upward from the upper end of the ice presser. In this case, even when the ice cutting progresses and the lower end of the ice guide part hits the cutting table and only the ice presser descends, the ice guide part slides along the auxiliary member. It is prevented from tilting and catching on an ice presser.

Furthermore, it is preferable that a roller for reducing friction when the ice guide member and the cutting table come into contact with each other is attached to the lower end of the ice guiding member or the cutting table. In this case, even when the ice guide member that rotates according to the cutting of ice descends, the ice guide member does not directly contact the cutting table, and the roller rotates on the upper surface of the cutting table. It is possible to prevent the table from rubbing against each other and being worn or damaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention embodying the present invention will be described in detail below with reference to the drawings.
(Example 1)
The ice cutting machine according to the first embodiment is an electric ice cutting machine for producing shaved ice. As shown in FIG. 1, the three parts of the driving unit 1, the ice cutting unit 2 and the ice receiving unit 3 are arranged from the top. It consists of

A rotary shaft 4 is inserted in the drive unit 1 in the vertical direction, and a motor 5 for rotating the rotary shaft 4 is attached to the rear part of the drive unit 1 as shown in FIG. The rotation of the motor 5 is transmitted to the rotary motion of the rotary shaft 4 through a small pulley 6 fitted to the shaft of the motor 5, a V belt 7 and a large pulley 8 fitted to the rotary shaft 4. . The motor 5, the small pulley 6, the V belt 7 and the large pulley 8 are rotation mechanisms.
An elevating mechanism 9 for elevating and lowering the rotary shaft 4 is provided below the pulley 8. As shown in FIG. 1, the elevating mechanism 9 is provided with a worm gear 10, a handle 11 for manually rotating the worm gear 10, and a brake fitting 12 for braking the rotation of the worm gear 10.

The lower end of the rotating shaft 4 is positioned in the ice cutting portion 2, and an ice presser 13 made of a substantially disk-shaped plastic is fixedly attached to the lower end of the rotating shaft 4. A plurality of nails 14 are embedded on the lower surface side of the ice retainer 13 so as to protrude downward. In addition, a cylindrical portion 13a having a diameter smaller than the outer diameter of the ice retainer 13 and having a common axis is projected upward from the upper end of the ice retainer 13. Further, the ice retainer 13 is covered with an alignment guide plate 15 having a tubular portion 15a inserted into the tubular portion 13a and a tapered portion 15b having a diameter that is slightly lower than the ice retainer 13. ing. The angle of the taper portion 15b is 30 ° from the horizontal plane. The tube portion 13a is an auxiliary member, and the alignment guide plate 15 is an ice guide member.
On the shoulder portion 15c between the cylindrical portion 15a and the taper portion 15b of the alignment guide plate 15, spring guide pins 16 are erected by screws at four positions at equal intervals. A spring 17 is inserted. The alignment guide plate 15 is pressed against the outer edge of the ice retainer 13 by the urging force of the alignment spring 17.

In addition, a mortar-shaped cutting plate 18 having a shallow bottom is provided at the lower end of the ice cutting part 2. The cutting plate 18 is inclined so as to gradually become deeper in the axial direction of the rotary shaft 4, and the inclination angle from the horizontal is 10 °. The cutting plate 18 is provided with a slit 19 that extends from the center to the vicinity of the periphery. A cutting blade adjusting mechanism 21 that fixes a cutting blade 20 that slightly protrudes obliquely upward from the slit 19 and can adjust the protruding amount of the blade tip is attached to the back side of the cutting plate 18 and scattered.

Further, the lower side of the cutting plate 18 is an ice receiving portion 3 having a space in which an ice receiver (not shown) can be placed.

Next, the operation and effect of the ice shaving machine of Example 1 will be described.
First, the handle 11 shown in FIG. 1 is manually rotated leftward. As a result, the worm gear 10 rotates and the rotating shaft 4 rises together with the ice retainer 13 and the alignment guide plate 15 to create a space for placing ice. Then, block-shaped rectangular parallelepiped ice I is placed on the cutting table 18. Here, since the cutting table 18 has a shallow mortar shape, a gap is formed between the bottom surface of the ice I and the cutting table 18, and the ice I makes point contact only at the corner of the cutting table 18 and the bottom surface. It becomes. For this reason, the contact area between the ice I and the cutting table 18 becomes extremely small and becomes slippery. Furthermore, when the ice I is placed on the cutting table 18, the ice I hardly comes into contact with the cutting blade 20, so that the sliding motion of the ice I is not prevented by the cutting blade 20. For this reason, in this state, the ice I moves toward the axial center with only a slight force applied to the ice I.

Further, by lowering the ice retainer 13 and the alignment guide plate 15, as shown in FIG. 4, the upper end angle of the ice I contacts the alignment guide plate 15, so that the ice I is as shown in FIG. 5. When the force fs is received from the tapered portion 15b of the alignment guide plate 15, the ice I slides and moves in the axial direction. Then, as shown in FIG. 6, the ice stops when the center of the ice I coincides with the axis. Further, the handle 11 is further rotated rightward, and the nail 14 of the ice presser 13 is digged into the ice I.

Thus, after preventing the ice I from being laterally moved by the ice presser 13, the receiver 22 is placed on the ice receiver 3 and the motor 5 shown in FIG. 2 is driven. As a result, the rotation of the motor 5 rotates the rotary shaft 4 via the pulley small 6, the V belt 7 and the pulley 8, and the cutting of the ice I by the cutting blade 20 is started. As shown in FIG. The cut ice is discharged toward the receiver 22. As the cutting proceeds in this manner, the rotary shaft 4 gradually descends, and eventually the lower end of the alignment guide plate 15 comes into contact with the cutting plate 18 as shown in FIG. Further, the alignment spring 17 is pushed and contracted, and only the ice holder 13 is further lowered. For this reason, the ice I is cut until it becomes thinner, and the yield in cutting the ice I is improved. Further, since the cylindrical portion 15a of the alignment guide plate 15 slides smoothly along the cylindrical portion 13a of the ice retainer 13, the alignment guide plate 15 is inclined and caught by the ice retainer 15 to brake the rotation. There is nothing.

(Example 2)
In the ice cutting machine according to the second embodiment, a roller 23 a is attached to the lower end of the alignment guide plate 23. About another structure, it is the same as that of the ice shaving machine of Example 1, About the same structure, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

In the ice cutting machine of the second embodiment, even if the cutting of the ice I progresses, the roller 23 a rotates on the cutting table 18 before the lower end of the rotating alignment guide plate 23 rubs against the upper surface of the cutting table 18. . Therefore, the alignment guide plate 23 can be prevented from rubbing against the upper surface of the cutting table 18 while rotating, and the alignment guide plate 23 can be prevented from being worn or damaged.

This invention is not limited to the description of the embodiments of the invention. Various modifications may be included in the present invention as long as those skilled in the art can easily conceive without departing from the description of the scope of claims.

The ice shaving machine of the present invention can be used for ice shaving machines for producing shaved ice and soft ice beverages.
