Description

  The present invention relates to an ice cutter that slices and cuts ice blocks to produce shaved ice, and more particularly to an ice cutter having an ice block lift mechanism.

  As is well known, an ice scraper has a horizontal circular area on which ice blocks are placed, and engages a horizontal metal table (usually made of an aluminum alloy) with a cutting blade attached to the back side and the top surface of the ice blocks. It has a plurality of picks and an ice presser that is rotated in a certain direction by a motor or the like.

  When slicing and cutting the ice block, the ice block is placed at the center of the circular area of the table, the ice presser is lowered and fixed to the upper surface of the ice block, and the ice presser is lowered while being rotated by a motor or the like. As a result, the lower surface of the ice block is sliced and cut by the cutting blade fixed to the table, and the cut piece falls downward from the gap between the table and the cutting blade and is received by the prepared container.

  By the way, if the ice block is left set on the table when the ice machine is stopped, the ice melts quickly due to the ambient temperature and heat transfer from the metal table. The problem is that when the ice melts, the yield will deteriorate, and the water receiving bat placed at the bottom of the ice shaving machine will soon fill up with the water that has melted and flowed down, and the surrounding water will get wet with the overflowing water There is also.

  If the ice block is left set on the table, the cutting blade protruding from the table bites into the lower surface of the ice block. For this reason, even if it tries to rotate the ice block by driving the ice scraper from the rest, the start of the rotation of the ice block is bad, the ice cut piece becomes rough, or an excessive load is applied to the motor. For this reason, the ice block is taken out of the ice scraper and stored in the freezer when the ice scraper is stopped.

  However, it takes time and effort to take out the ice block from the ice scraper and store it in the freezer every time the ice scraper is stopped, and the possibility of the ice block being contaminated when the ice block is taken in and out increases. Therefore, as in Patent Document 2, a plurality of lift members that can protrude on the table are arranged, and a lift mechanism that lifts the lower surface of the ice block from the table by lifting the lift members when the ice-shaving machine is stopped is equipped. An ice machine has been proposed. In this ice cutter with a lift mechanism, when the ice block presser is raised to the rising end, the upper surface of the ice presser pushes up the end of the link member, and the lift member on the table side rises in conjunction with this. ing.

JP 2009-52848 A

  However, since the conventional ice lump lift mechanism needs to dispose the link member over a long distance from the ice retainer to the table, the link member is large and complicated, and easily causes a failure. Further, since the ice presser must be raised to the rising end one by one, the operation of raising the ice presser is troublesome when it is desired to temporarily raise the ice block for a very short time.

  In addition, Patent Document 1 discloses an ice lump lift mechanism that raises and lowers a lift member with a motor and a cam arranged behind the table instead of a link mechanism that interlocks with the ice presser. However, when the motor is used, the apparatus becomes large. This greatly increases the cost and weight of the ice machine. Also, in the case of the usage method in which the ice block is frequently moved up and down at short time intervals, the electric lift mechanism is inconvenient because the operator's wet hand touches the motor switch. It is difficult to confirm whether or not the lift member hidden on the table actually protrudes on the table in the switching state of the switch.

  An object of the present invention is to provide an ice shaving machine having a compact and low-cost ice lump lift mechanism. Another object of the present invention is to provide an ice scraper equipped with an ice lump lift mechanism that can easily visually check the state of the lift member.

  In order to achieve the above-mentioned object, the present invention has a horizontal circular region on which an ice block is rotatably mounted, a table with a cutting blade attached to the back side, and a top surface of the ice block that is detachably engaged and rotationally driven. An ice presser rotated by a means, and a lift member disposed so as to protrude in a horizontal circular region of the table to float the lower surface of the ice block from the table, on the back side of the table, A notch ring shape is formed so as to avoid the cutting blade, an operation member that can be turned along the circumferential direction of the horizontal circular region is disposed, and the lift member is supported on the upper surface of the operation member. An ice-cutting machine characterized in that an inclined cam inclined along the turning direction is disposed, and the lift member is moved up and down by the inclined cam by turning the operation member.

  According to the present invention, the lift member that floats the ice block and the operation member that lifts and lowers the lift member can be arranged close to each other on the back side of the table, so that the ice block lift mechanism can be made compact and low in cost. In addition, since the operation member that raises and lowers the lift member is swung along the circumferential direction of the table, the swivel position of the operation member is highly visible, and the state of the lift member can be easily confirmed.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In addition, about the part same or the same kind in drawing, the same number is attached | subjected and description is abbreviate | omitted suitably.

  As shown in FIGS. 1A and 1B, an ice cutting machine according to an embodiment of the present invention includes a vertical frame 1 and an aluminum alloy attached at a substantially intermediate position in the height direction of the frame 1 as in the conventional product. A table 2 made of metal, a rotating shaft 3 that is vertically arranged on the upper part of the frame 1 and supported by a motor and a speed reduction mechanism so as to be rotatable and movable up and down, and a table 2 at the lower end of the rotating shaft 3. The ice presser 4 mounted oppositely, the ice presser lifting handle 5 provided on the right side of the frame 1, the blade adjustment knob 6 provided on the left side of the table 2, and the lower part of the ice cutter. A water receiving bat 7 is provided.

  A transparent semi-cylindrical resin cover member 8 is pivotally disposed on the peripheral edge of the table 2. The cover member 8 can be swung from the front side of the front side to the left side of the front side along the periphery of the table 2 at an angle of about 180 °, and the front side of the table 2 is covered with the cover member 8 to prevent the ice block from popping out when using an ice shaving machine. It is trying to close with. That is, if the ice press pick bite into the ice block is sweet or the bite position is offset, the ice block may come off the ice presser while the ice block is rotating. Then, since the ice block may be vigorously blown to the outside of the table 2 by centrifugal force, the cover member 8 is closed as shown in FIG. 1B when the ice shaving machine is used.

  An ice lump lift lever 20 as an operation lever is disposed on the right side of the table 2 toward the ice cutting machine. This ice lump lift lever 20 lifts the ice lump placed on the table 2 from the table 2 at a predetermined height (about 8 mm in this embodiment) when the ice machine is stopped. When it touches the table 2 and moves to the front side of the front, an ice block floats.

  As shown in FIG. 2, a horizontal circular area 2a is formed on the upper surface of the table 2, and an ice block C (usually 13 cm square) is set at the center of the circular area 2a. An annular rib 2b for guiding the cover member 8 is formed at the peripheral edge of the circular region 2a.

  Circular through holes 2c penetrating in the vertical direction are formed at four locations in the circumferential direction of the circular region 2a of the table 2. Each through hole 2c is arranged on the circumference of a predetermined radius centered on the center of the circular area 2a so as to be positioned below the ice block C, and cylindrical lift pins 21a-21d are inserted into the through holes 2c. Has been. Further, a long hole 2d is formed from the center of the circular region 2a toward the front side in the radial direction, and the cutting attached to the tool post 10 on the back side of the table 2 (see FIGS. 8A and 9A) in the long hole 2d. The cutting edge 9a of the blade 9 is inserted.

  The lift pins 21a-21d are integrally formed on the upper surface of the lift member 21 shown in FIGS. 3A to 3C. The entire lift member 21 including the lift pins 21a-21d is integrally formed of resin. A compression spring 22 is disposed around each lift pin 21a-21d in a space between the table 2 and the lift member 21, as will be described later, so that the lift member 21 is biased downward by the compression spring 22. It has become.

  The lift member 21 is substantially C-shaped in plan view, and lift pins 21a-21d are formed on the upper surface thereof in the same arrangement as the through holes 2c. Each lift pin 21a-21d has the same height, and a hollow portion 23 is formed inside the lift pin 21a-21d for moldability.

  A hemispherical recess 24 facing downward is formed at the lower end of each lift pin 21a-21d, and a metal sphere 25 is fitted into the recess 24 as shown in FIG. It is supposed to be combined. The spherical body 25 is in sliding contact with a groove portion 36c of an inclined cam 36 described later.

  As shown in FIGS. 8A and 9A, three stays 30 extending in a straight line with the same length downward are arranged at three positions on the lower surface of the table 2. An operation plate 31 as an operation member for raising and lowering the lift member 21 is supported on the lower ends of the three stays 30. The operation plate 31 is made of metal and has a C shape in a plan view as shown in FIG. 5A, and its peripheral portion is slid from the vertical direction by a resin U-shaped guide 32 fixed to the lower end portion of the stay 30. It is supported by being sandwiched freely. The operation plate 31 can turn in the circumferential direction of the circular region 2 a while sliding with the guide 32.

  As shown in FIG. 5A, a resin cam member 33 having a C-shape in a plan view is disposed on the operation plate 31 as shown in FIG. 5A. The cam member 33 is screwed to the operation plate 31 at five locations S1 to S5. Further, an ice lump lift lever 20 that extends linearly outward in the radial direction is fixed to the upper surface of one end in the circumferential direction of the operation plate 31 via a metal fitting 34. A spherical red knob 35 made of resin is fixed to the tip of the ice lump lift lever 20. The knob 35 is held so that the operation plate 31 can be turned in the horizontal direction.

  A stopper pin 37 is disposed on the lower surface of the other end in the circumferential direction of the operation plate 31. The ice lump lift lever 20 abuts against the side edge 30a of the stay 30 and serves as a stopper when moving to the front right side, and the stopper pin 37 abuts against the stopper 30b of the opposite stay 30 and the front of the ice lump lift lever 20 It is configured to serve as a stopper when moving to the near side.

  When the lift pin 21a-21d is moved to the lowest position, the knob 35 is moved to the front right side of the ice shaving machine as shown in FIG. 7A, and when the lift pin 21a-21d is moved to the highest position, the knob 35 shown in FIG. It is designed to move to the front side of the ice machine. Thus, since the ice lump lift lever 20 is only moved in the horizontal direction, the operability is good.

  In addition, since the left and right operation positions of the ice lump lift lever 20 can easily determine whether the lift pins 21a-21d are raised or lowered, the ice cutter can be driven carelessly while the lift pins 21a-21d are raised. Further, it is possible to prevent a mistake that the ice block C is taken out while the lift pins 21a-21d are lowered. In particular, since the red knob 35 attached to the tip of the ice lump lift lever 20 has good visibility, it helps to prevent erroneous operation. The swivel angle of the ice lump lift lever 20 can be designed freely. In this embodiment, the swivel angle is designed at about 60 °, but can be designed at an arbitrary angle of 60 ° or more or 60 ° or less.

  On the back side of the table 2, a tool post 10 to which the cutting blade 9 is attached is disposed slightly to the left as shown in FIGS. 8A and 9A. For this reason, the ice lump lift lever 20 is operated on the side opposite to the tool rest 10, that is, in the direction in which the cutting edge 9 a of the cutting blade 9 faces, so that the ice lump lift lever 20 and its mounting bracket 34 do not interfere with the tool rest 10. Thus, the lift pins 21a-21d are lowered. Such an operation direction of the ice lump lift lever 20 is very convenient considering that the dominant hand of the operator is often the right hand.

  The cam member 33 on the operation plate 31 has an inclined cam 36 that slidably supports the lower ends of the lift pins 21a-21d, and moves the lift pins 21a-21d up and down by rotating the operation plate 31 in the circumferential direction. It is supposed to let you. Four inclined cams 36 are arranged in the circumferential direction corresponding to the four lift pins 21a-21d, and each inclined cam 36 has the same shape.

  As shown in FIG. 5B and FIG. 6, the inclined cam 36 is formed by connecting the lowest portion 36a and the highest portion 36b with an inclined groove portion 36c, and a hemispherical fitting portion 36d on the highest portion 36b and the lowest portion 36a. 36e is formed. The groove portion 36c is formed in a circular arc shape in cross section, and the sphere 25 can roll along the groove portion 36c.

  The end portion on the upstream side and the end portion on the downstream side of the groove portion 36c continue to the highest portion 36b and the lowest portion fitting portions 36d and 36e through the step portions 36f and 36g. The step portions 36f and 36g are formed so that the side of the fitting portions 36d and 36e is deep, and when the sphere 25 enters and leaves the fitting portions 36d and 36e, a click feeling is generated at the step portions 36f and 36g. It is like that.

  The operator of the ice milling machine feels the click feeling through the ice lump lift lever 20 so that the lift pins 21a-21d reach the lowest part 36a or the highest part 36b or leave the lowest part 36a or the highest part 36b. It is possible to grasp this clearly. The fitting portion 36d and the stepped portion 36f of the highest portion 36b prevent the sphere 25 at the lower end of the lift pin 21a-21d from being naturally separated from the fitting portion 36d and moving down the groove portion 36c due to the weight of the ice block C. There is also a lock function.

  Since the spherical body 25 can roll along the groove portion 36c, the movement resistance of the spherical body 25 with respect to the groove portion 36c is small, the turning movement of the ice lump lift lever 20 is smooth, and the ice lump lift lever 20 is smoothly moved with a light force. Can be moved. A new ice block used for an ice scraper usually has a weight of about 2 kg, but since the movement resistance of the sphere 25 is small, the lever can be easily operated with a light force.

  Next, an operation for cutting an ice block with the above-described ice-cutting machine will be described. Before operating the ice cutter, the cover member 8 is opened to open the front of the table 2, the cutting blade 9 is adjusted to a predetermined protruding amount with the blade adjusting knob 6, and the ice block presser 4 is raised to the upper retracted position. Make sure. And the ice block C taken out from the freezer is set in the center of the circular area 2a of the table 2 as shown in FIG.

  Next, the ice presser lifting handle 5 is turned to lower the ice presser 4, the pick on the lower surface is engaged with the upper surface of the ice block, the ice scraper is turned on, the motor is driven, and the rotary shaft 3 is rotated. As a result, the ice block C rotates on the table 2 together with the ice retainer 4, and the lower surface of the ice block C is cut by the cutting blade 9, so that the ice cutting piece falls downward from the slit and is received by a predetermined container. It is done.

  When temporarily suspending the ice machine, turn off the ice machine and stop the motor. Next, the cover member 8 is left closed as it is, and the ice presser lifting handle 5 is turned to raise the ice presser 4 by about 1 cm. Thereafter, the knob 35 of the ice lump lift lever 20 is held and moved from the front right side to the front front side as shown in FIGS. 7A to 7B. When the ice lump lift lever 20 is moved to the near side in this way, the left stopper pin 37 of the operation plate 31 comes into contact with the stopper portion 30b of the left stay 30, and the ice lump lift lever 20 is moved to the left. Can not be.

  By operating the ice lump lift lever 20 in the left direction, the operation plate 31 is turned clockwise, and the spherical body 25 is moved relatively from the lowest portion 36a to the highest portion 36b by the inclined cam 36. 9B and the right side of FIG. 10, the lift pins 21 a to 21 d protrude on the table 2 against the compression spring 22.

  As a result, the ice block C on the table 2 is lifted horizontally by the lift pins 21a-21d, and a predetermined gap D (in this embodiment, about the amount of protrusion of the lift pins 21a-21d between the ice block bottom surface and the table 2). 8 mm) is formed. Then, heat conduction from the table 2 to the lower surface of the ice block C is blocked by the gap D, and the melting of the ice block C is suppressed.

  Since the lift pins 21a-21d are made of resin, the heat transfer rate is low, and the melting of the ice blocks C is suppressed even at the contact points of the lift pins 21a-21d. The amount of protrusion of the lift pins 21a-21d is arbitrary, but it is preferable that the height of the ice block C is such that the lower surface of the ice block C is completely separated from the table 2 and the cutting blade 9. Usually, if there is a protrusion amount of 2 to 8 mm, the lower surface of the ice block C is surely separated from the table 2 and the cutting blade 9.

  When the use of the ice scraper is finished, the cover member 8 is opened from this state, the ice block C is taken out, and stored in the freezer. At this time, since the gap D is formed between the lower surface of the ice block C and the table 2, the ice block C can be easily taken out without unexpectedly touching the cutting edge 9a of the cutting blade 9. Further, when the ice block C that has become thin and can no longer be used is taken out of the table 2 and discarded, the ice block C has been in close contact with the table 2 and has been very difficult to remove, but the ice scraper of the present invention has the lift pins 21a-21d. Since the gap D can be easily formed by the protrusion, the thin ice block C can be easily taken out.

  When operating the ice cutter again from the resting state, the ice lump lift lever 20 is moved from the front side to the right side. When the ice lump lift lever 20 is moved in this manner, the ice lump lift lever 20 comes into contact with the side edge 30a of the stay 30, and the ice lump lift lever 20 cannot be moved rightward any further.

  By the above movement of the ice lump lift lever 20, the sphere 25 moves relatively from the highest portion 36b to the lowest portion 36a, and the lift pins 21a-21d move downward from the table 2 as shown in FIGS. 8B and 10 left. Then, it is completely stored in the through hole 2c. As a result, the lower surface of the ice block C comes into direct contact with the upper surface of the table 2, and the lower surface of the ice block can be sliced by the cutting blade 9. Thereafter, the ice block C can be sliced and cut in the same manner as described above by turning the ice retainer lifting handle 5 to lower the ice retainer 4 and then driving the motor.

  When the sphere 25 moves into and out of the fitting portions 36d and 36e of the inclined cam 36 by operating the ice lump lift lever 20 in the left and right direction, the force of the step portions 36f and 36g at the inlets of the fitting portions 36d and 36e and the compression spring 22 Click feeling occurs. The click feeling is transmitted to the operator's hand through the operation plate 31 and the knob 35 of the ice lump lift lever 20, and the operator engages the sphere 25 with the fitting portions 36d and 36e or leaves the fitting portions 36d and 36e. I can clearly know what I did.

  Therefore, the operation plate 31 and the lift pins 21a-21d can be reliably operated by the ice lump lift lever 20. Further, when the sphere 25 is fitted into the fitting portions 36d and 36e, the turning of the operation plate 31 is lightly locked, so that the operation plate 31 is prevented from moving naturally in the left-right direction due to vibration of the motor or the like. The

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, A various deformation | transformation is possible. For example, although the number of lift pins of the lift member is four in the above-described embodiment, the number of lift pins may be at least three, and may be five or more in order to improve stability. Further, the lift pins are not necessarily arranged on the same circumference, and for example, a plurality of lift pins can be arbitrarily arranged on a plurality of concentric circles.

  In the above embodiment, the ice lump lift lever 20 is moved from the right side of the ice scraper to the front front side to raise the lift pins 21a-21d. However, the moving range of the ice lump lift lever 20 can be freely set. It is also possible to lift the lift pins 21a-21d by moving from the left side of the ice shaving machine to the front front side.
