Description

  The present invention relates to an ice lump unloading device which is disposed in an ice storage chamber of an ice storage for storing ice blocks produced by an ice making mechanism of an ice making machine and takes out the ice blocks in the ice storage chamber to the outside.

  As an automatic ice making machine for continuously producing a large amount of ice blocks, for example, an ice making machine provided with an ice making mechanism 18 and a freezing mechanism (not shown) at the upper part of an ice storage 12 in which an ice storage chamber 14 shown in FIG. 7 is defined. A stack-on type in which the units 16 are loaded is widely used. The ice storage 12 is constituted by a heat insulating box body filled with a heat insulating material between an inner box and an outer box, and an upper part thereof is opened so that an ice block C falling from above can be received. Further, an outlet 22 for the ice block C is opened on the front side of the ice storage 12, and the outlet 22 is closed by a heat insulating door 24 so as to be opened and closed. In the ice making machine 10, the ice storage 12 and the ice making unit 16 are arranged in a vertical relationship, and generally the ice block C is discharged from the ice making mechanism 18 to the ice storage chamber 14 using gravity. An ice storage 12 is disposed below the ice making unit 16. And when using the ice block C stored in the ice storage chamber 14 of the ice storage 12, the ice block C is carried out from the take-out port 22 by a scoop or the like with the heat insulating door 24 opened.

  As described above, since the ice storage 12 is located in the lower part of the ice making machine 10, the ice lump C is manually carried out by bending the waist and making an unreasonable posture. It was. In addition, the ice blocks C stored in the ice storage chamber 14 may stick to each other over time or due to other factors, and so-called arching may occur. There is a problem that the work of breaking C is required and further burdens the operator.

Therefore, an ice making machine having an ice storage in which an ice lump unloading device is provided in advance at the bottom of the ice storage chamber has been proposed (see, for example, Patent Document 1). As shown in FIG. 8, an ice making machine 11 in which an ice storage 12 and an ice making unit 16 are integrally formed is also known as an ice making machine equipped with an ice lump carrying-out device. The device 30 includes a geared motor 32 with a speed reducer disposed on the front side of a cover body that is detachably attached to the front opening of the ice storage 12, and an ice lump delivery screw 34 connected to the geared motor 32. It consists of. The ice lump delivery screw 34 is composed of a rotating shaft 36 rotated by the geared motor 32 and fins 38 spirally provided at a predetermined pitch on the outer periphery of the rotating shaft 36, and at the bottom of the ice storage chamber 14. It extends so as to incline upward from the rear toward the ice discharge port 26 provided in the front. Accordingly, when the ice block C is driven and controlled in a state where a large number of ice blocks C discharged from the ice making unit 16 are stored at the bottom of the ice storage chamber 14, the ice block delivery screw 34 is rotated in a predetermined direction. Each ice block C facing the gap between the fins 38 is sequentially moved to the ice discharge port 26 side along the guide wall (the bottom surface of the ice storage chamber 14 facing the ice block delivery screw 34) 14a, and then discharged from the ice discharge port 26. It is like that. In addition, the same code | symbol is attached | subjected to the component same as the ice making machine 10 shown in FIG.
Japanese Utility Model Publication No. 61-181286

  By the way, in the ice lump unloading device 30 described above, when the ice lump delivery screw 34 that is the conveying means for the ice lump C is rotated, the ice lump C may be sandwiched between the fin 38 of the screw 34 and the guide wall 14a. . In other words, the ice block C that has been bitten prevents the rotation of the ice block delivery screw 34 and prevents the smooth transfer of the other ice blocks C, and it takes time to take out the ice block C. It was difficult to take out ice block C. Further, it is pointed out that the crushing sound generated when the ice block C sandwiched between the ice block delivery screw 34 and the guide wall 14a is broken is harsh.

  That is, the present invention has been proposed to solve these problems inherently in the ice lump unloading device according to the prior art, and it has been proposed to suitably solve these problems. An object of the present invention is to provide an ice lump unloading device.

In order to overcome the above-mentioned problems and achieve the intended purpose, an ice lump unloading device according to the present invention includes:
An ice lump unloading device that is disposed at the bottom of the ice storage chamber and unloads the ice lump stored in the ice storage chamber,
A hollow cylindrical shape which is disposed at the bottom of the ice storage chamber and is rotatable around a central axis, has an ice mass intake port at a portion facing the ice storage chamber, and a discharge port at a portion facing the outside of the ice storage chamber. An ice guide,
A fin disposed on the inner peripheral surface of the ice guide and extending spirally in the axial direction of the ice guide;
It comprises driving means connected to the ice guide and rotating the ice guide,
The intake opening is set so that the opening width in the circumferential direction of the ice guide is approximately half the circumference of the ice guide,
The ice guide and the fin are integrally rotated by the driving means, so that the ice blocks taken from the intake opening facing the ice storage chamber can be transported and discharged from the discharge opening approximately every half circumference. It is characterized by that.

  According to the ice lump carrying-out device according to the present invention, the fins are spirally arranged on the inner peripheral surface of the ice guide, and the ice guide and the fins are integrally rotated. Since the ice blocks are smoothly carried out without being bitten, a large amount of ice blocks can be released in a short time. Moreover, since it is comprised so that the encroachment of an ice lump may be avoided, there is no generation | occurrence | production of the crushing sound by the encircling ice lump, and a quiet ice lump carrying-out apparatus can be obtained. If the opening width of the ice guide in the intake port in the axial direction is set to a size approximately half the circumference of the ice guide, the inside of the ice guide will always be empty each time the intake port faces the ice storage chamber as the ice guide rotates. Therefore, it becomes possible to take in a stable amount of ice blocks. By providing a time zone during which the ice block is not taken into the ice guide, there is room in the ice guide and the ice guide can be smoothly transported without clogging.

  In addition, by setting the interval between the blade portions adjacent to each other in the axial direction of the fin so as to increase from the intake port toward the discharge port, blocking of ice blocks inside the ice guide can be suppressed, and smoother Can transport ice blocks. The intake port is preferably set so that the opening width in the axial direction of the ice guide is substantially the same as the interval between the adjacent blade portions facing the intake port, whereby the ice block of the ice storage chamber is preferably taken into the ice guide. Can be included. Further, since the ribs are arranged on the outer peripheral surface of the ice guide in a spiral shape opposite to the spiral direction of the fins, the ribs are stored in the ice storage chamber as the ice guide rotates, and the ice blocks are taken into the intake port. It pushes toward and helps to take in the ice block from the intake, and also has the effect of eliminating the arching and blocking of the ice block in the ice storage chamber. Furthermore, since the opening edge located on the rear side in the rotation direction at the intake port has an R shape, it is possible to avoid the ice block from being caught between the installation recess and the opening edge. And the effect which can take in an ice lump more smoothly from an intake port by providing a collar part in the position corresponding to the intake port in an installation recessed part is show | played.

  Next, the ice lump unloading apparatus according to the present invention will be described below with reference to the accompanying drawings by giving a preferred embodiment. For convenience of explanation, the same components as those of the ice making machine shown in FIG. 7 or FIG. Here, in the ice storage of the ice making machine, the side surface where the discharge port is provided is the front side.

The discharge port 46 can be discharged to the outside. In the embodiment, a stirring means 80 is installed above the ice lump unloading device 40 to agitate the ice lump C stored in the ice storage chamber 14 and help the ice lump C to be taken into the ice lump unloading device 40. .

  As shown in FIG. 1 or FIG. 2, the ice storage 12 in which the ice lump unloading device 40 of the embodiment is installed is a heat insulating process in which a space portion defined by an inner box 12a and an outer box 12b is filled with a heat insulating material 12c. The upper body is opened and can receive the ice block C released from the ice making mechanism. An ice storage chamber 14 for receiving and storing ice blocks C released from an ice making mechanism disposed above is defined in the ice storage 12. An installation recess 20 in which a cylindrical ice guide 42 is installed is formed in the bottom of the ice storage chamber 14, and the installation recess 20 is formed in a substantially arc shape that allows the ice guide 42 to be inserted (see FIG. (See FIG. 3). In addition, an opening 12 d that communicates with the installation recess 20 is provided in a wall portion on the front side of the ice storage 12 at a position spaced from the bottom surface of the ice storage 12 by a required dimension. The bottom portion of the ice storage chamber 14 is formed to incline upward from the rear side of the ice storage chamber 14 toward the opening 12d, and the installation recess 20 inclines along the bottom portion of the ice storage chamber 14 accordingly. ing. Further, the bottom portion of the ice storage chamber 14 is inclined downward so as to guide the ice block C stored toward the intake port 44 located at the inclined lower end portion of the installation recess 20 in the ice guide 42. It has a shape.

  As shown in FIG. 3, the installation recess 20 has a wall portion (on the right side in the front view) located on the front side in the rotation direction of the ice guide 42 projecting above the ice guide 42 and on the rear side in the rotation direction. The wall portion (on the left side when viewed from the front) is located on the side of the ice guide. In other words, in the ice guide 42 fitted in the installation recess 20, the installation recess 20 is covered with approximately 3/4 of its peripheral surface, and only the quadrant area on the upper left side of the peripheral surface in a front view is an ice storage chamber. 14 In addition, a flange that protrudes above the ice guide 42 by a predetermined length from the front side to the rear side in the rotation direction of the ice guide 42 at a position corresponding to the intake port 44 in the installation recess 20. 20a is provided (see FIG. 5). Therefore, when the intake opening 44 faces the ice storage chamber 14, the opening is widened. In addition, a drainage port 78 for discharging ice melt water, washing water, etc. in the ice storage chamber 14 is provided at the inclined lower end portion of the installation recess 20, and its tip penetrates the ice storage 12 to the outside. It is open to.

  The ice guide 42 has a hollow cylindrical body as a main body, and is provided with a take-in port 44 at one end peripheral surface thereof so as to open toward the ice storage chamber 14 and at the other end of the outside of the ice storage 12. A discharge port 46 is provided, and the intake port 44 is detachably fitted so as to be positioned at the inclined lower end of the installation recess 20. The axial length of the ice guide 42 is such that when the ice guide 42 is installed in the installation recess 20, the end on the discharge port 46 side (the other side) is exposed to the outside of the ice storage 12. The dimension to be set is set (see FIG. 1). The end face of the ice guide 42 on the side where the intake 44 is opened is closed, and a rotating shaft 50 connected to the motor 56 provided in the ice storage 12 is provided on the closed end face. . The axis of the ice guide 42 and the rotating shaft 50 are located on the same straight line.

  The intake port 44 is formed by cutting out the circumferential surface on one end side of the ice guide 42 over a half circumference. The opening width of the intake port 44 in the front-rear direction (the axial direction of the ice guide 42) is an area corresponding to the intake port 44 in the fin 48 spirally disposed on the inner peripheral surface of the ice guide 42. Are set to be approximately the same size as the interval P between the adjacent blade portions 48a, 48a located at. In addition, a round bar steel is disposed over the opening edge 44a on the opening edge 44a located on the rear side in the rotation direction of the intake port 44, and reinforces the opening edge 44a in contact with the ice block C, The opening edge 44a has an R shape. Further, the opening edge 44 a located on the rear side in the rotation direction of the intake port 44 may be an acute angle with respect to the circumferential angle of the fin 48. In the embodiment, the rounded steel bar is disposed on the opening edge 44a so as to have an R shape. However, the opening edge 44a itself is chamfered so as to eliminate the catch of the ice block C. Good.

  The fins 48 are plate-like bodies provided upright on the inner peripheral surface of the ice guide 42, and are continuously arranged in a spiral shape over the entire axial direction of the ice guide 42. Here, in the embodiment, when the ice guide 42 is rotated clockwise in the front view, the ice block C is caused by the fins 48 from the intake port 44 side along the inner peripheral surface of the ice guide 42. The spiral direction is set so as to be guided toward the 46 side. In addition, the rising dimension of the fin 48 of the embodiment is set to be smaller than the radius of the ice guide 42. And the space | interval P of the blade | wing parts 48a and 48a which are arrange | positioned spirally on the internal peripheral surface of the said ice guide 42, and is adjacent is set so that it may become large as it goes to the discharge port 46 side from the said intake port 44 side. . For example, in the embodiment, the interval P between the blade portions 48a, 48a is arranged so as to increase by 3 mm toward the discharge port 46 side.

  Further, on the outer peripheral surface of the ice guide 42, protruding ribs 54 are continuously provided in a spiral shape. The spiral direction of the rib 54 is opposite to the spiral direction of the fin 48. That is, when the ice guide 42 is rotated in a direction to guide the ice block C taken into the ice guide 42 by the fins 48 toward the discharge port 46, the ice guide 42 is arranged on the outer peripheral surface of the ice guide 42. The spiral direction of the rib 54 is set so that the ice block C in the ice storage chamber 14 is pushed toward the intake port 44 side by the provided rib 54.

  Next, the installation state of the ice guide 42 will be described. The ice guide 42 is installed such that the end on the discharge port 46 side protrudes from the opening 12d of the ice storage 12, and the most part on the intake port 44 side is recessed in the front-rear direction at the bottom of the ice storage chamber 14. It is inserted into the recess 20, extends in the front-rear direction of the ice storage 12, can rotate in the circumferential direction, and is detachable in the axial direction as will be described later. Specifically, the ice guide 42 is disposed on the front wall of the ice storage 12, and is released by a pair of bearings 62 and 62 provided in a support member 60 having a hole aligned with the opening 12d. The end portion on the outlet 46 side is supported from below, and the end portion on the intake port 44 side is supported by the bearing 28 provided at the inclined lower end portion of the installation concave portion 20, thereby providing the installation concave portion. It can be rotated independently of 20 (see FIG. 1). Further, since the installation recess 20 is inclined downward from the front side toward the rear side, the ice guide 42 is also inclined downward from the discharge port 46 side toward the intake port 44 side. Is provided with an inclination of about 20 °. Further, a required gap is provided between the installation recess 20 and the outer peripheral surface of the ice guide 42 to allow the rib 54 provided on the outer peripheral surface of the ice guide 42 to rotate.

  As shown in FIG. 4, the rotation shaft 50 of the ice guide 42 and the drive shaft 58 of the motor 56 are connected via an engaging member 64, and the bearings 62, 62 and 62 are driven by the rotation of the motor 56. The ice guide 42 rotatably supported by the bearing 28 rotates in a predetermined direction. The engaging member 64 is a cylindrical body whose both ends are open, and a first engaging hole 66 (see FIG. 4 (d)) having a D-shaped cross section is formed on one end thereof, and a circular section having a circular cross section is formed on the other. Two engagement holes 68 (see FIG. 4C) are formed. An engagement pin 70 is installed in the second engagement hole 68 in a direction orthogonal to the axis of the engagement member 64 (see FIG. 4C). Further, the drive shaft 58 of the motor 56 is formed in a cross-sectional D shape that matches the cross-sectional shape of the first engagement hole 66. That is, the engaging member 64 in which the first engaging hole 66 is extrapolated to the drive shaft 58 is rotatable integrally with the drive shaft 58.

  A concave groove 52 is formed at the tip of the rotation shaft 50 of the ice guide 42. The concave groove 52 is positioned on the bottom side of the first concave groove 52a that is set to a width that allows the engagement pin 70 of the engagement member 64 to be inserted, and is circular in the rotational direction. The second groove 52b is cut out in an arc shape (see FIG. 4B). The rotating shaft 50 is inserted into the second engaging hole 68 with the engaging pin 70 and the first concave groove 52a aligned, and the rotational direction is determined with the engaging pin 70 reaching the second concave groove 52b. By rotating the ice guide 42 in the same direction, the engagement pin 70 is engaged and held between the second groove 52b and the first groove 52a. That is, the rotation of the drive shaft 58 of the motor 56 is transmitted to the ice guide 42 under the engaging action of the engaging pin 70 and the groove 52. Further, when the ice guide 42 is rotated in the direction opposite to the rotation direction, the engagement pin 70 faces the first concave groove 52a, and the ice guide 42 is further pulled out to the front side. 50 is released, and the ice guide 42 can be pulled out from the opening 12d and removed from the ice storage 12.

  As shown in FIG. 1, a stirring means 80 for stirring the ice block C stored in the ice storage chamber 14 is disposed above the ice guide 42. The agitation means 80 includes a pair of agitation rings 84 and 84 disposed on a shaft portion 82 installed horizontally in the ice storage chamber 14 and a rotation means 86 such as a motor that urges the shaft portion 82 to rotate. Composed. The shaft portion 82 extends horizontally in the front-rear direction in the ice storage chamber 14, and is positioned on a vertical line of the axis of the ice guide 42. A belt 88 is wound between a pulley on the output shaft side of the rotating means 86 and a pulley on the shaft portion 82 side, and the rotation of the rotating means 86 is transmitted to the shaft portion 82. The stirring ring 84 is obtained by winding a round steel bar in a spiral shape (see FIG. 6), and the stirring rings 84 and 84 facing each other are fixed to the shaft portion 82 so that the spiral direction is symmetric, As the shaft portion 82 rotates, the shaft portion 82 rotates integrally. The stirring rings 84 and 84 are set in a spiral direction so as to urge the ice mass C toward the center of the ice storage chamber 14 as the shaft portion 82 rotates.

(Effects of Example)
Next, the operation of the ice lump unloading apparatus according to the embodiment will be described. First, the process of carrying out the ice block C by the ice block carrying-out device 40 will be described with reference to FIG. (1) When the motor 56 is driven, the rotation of the drive shaft 58 is transmitted to the rotation shaft 50 via the engagement member 64, and the ice guide 42 starts to rotate. At this time, the ice guide 42 and the fin 48 rotate integrally. (2) The intake port 44 closed by the installation recess 20 is opened at the position facing the ice storage chamber 14 between the installation recess 20 and the flange 20a as the ice guide 42 rotates. (See FIG. 5A). (3) The ice block C stored in the ice storage chamber 14 falls from the intake port 44 and is taken into the ice guide 42. Here, the bottom of the ice storage chamber 14 is provided with a hopper-like slope, and is formed so that the position where the intake port 44 is provided is the lower end of the slope. Therefore, the ice blocks stored in the ice storage chamber 14 C is suitably guided to the intake port 44 under the action of gravity. (4) As the ice guide 42 further rotates, the intake port 44 opened to the ice storage chamber 14 is covered with the flange portion 20a to narrow the intake port 44, and the inner peripheral surface of the ice guide 42 The ice blocks C taken into the ice guide 42 are conveyed toward the discharge port 46 along the inner peripheral surface by the fins 48 arranged on the surface. However, since the flange portion 20a and the intake port 44 are separated from each other, the ice block C is preferably guided into the ice guide 42 through the intake port 44 without being caught. (5) The ice block C is taken into the ice guide 42 each time the take-in port 44 faces the ice storage chamber 14 by the rotation of the ice guide 42. (6) The ice block C reaching the discharge port 46 established on the inclined upper end side of the ice guide 42 is discharged to the outside from the discharge port 46. These series of steps are continuously performed as the ice guide 42 rotates.

  As described above, the ice lump unloading device 40 is configured to integrally form the ice guide 42 that guides the ice lump C and the fins 48 that convey the ice lump C, which are the means for unloading the ice lump C, and rotate integrally. Therefore, the ice block C transported inside the ice guide 42 does not bite inside the ice guide 42. Further, since the ice guide 42 facing the ice storage chamber 14 is formed in a cylindrical shape and there is no space for the ice block C to fit between the wall surface of the installation recess 20, the ice guide 42 which is a rotating portion and the installation are provided. There is no possibility of causing the ice block C to bite into the recess 20. Since the ice guide 42 is covered with the installation recess 20 and only a part of the ice guide 42 faces the ice storage chamber 14, there is an advantage that the load against rotation due to the weight of the ice block C loaded on the ice guide 42 can be reduced. . That is, since there is no factor that hinders the transport of the ice block C by the ice guide 42, the ice block C can be transported smoothly, and a large amount of the ice block C can be taken out from the ice storage 12 in a short time. Furthermore, since the ice guide 42 which is the rotating part is configured to avoid the biting of the ice block C, no crushing sound is generated by the bited ice block and noise can be prevented. In addition, since the ice lump unloading device 40 of the embodiment is installed obliquely with the discharge port 46 as an upper end, there is an advantage that a space for placing a container such as a bucket can be secured below the discharge port 46.

  In the ice guide 42, the interval P between the adjacent blade portions 48a, 48a in the fin 48 is set so as to increase from the intake port 44 toward the discharge port 46. Therefore, the adjacent blade portions 48a, 48a, Generation of blocking of the ice block C can be prevented between 48a, and smooth transfer of the ice block C is achieved.

  Further, when the ice guide 42 is rotated, the ribs 54 protruding in a spiral shape on the outer peripheral surface of the ice guide 42 abut against the ice block C when facing the ice storage chamber 14 from the installation recess 20, and the ice block toward the intake port 44. Functions like pressing C. Therefore, when the ice block C stored in the ice storage chamber 14 is blocked or arched, the rib 54 pushes the ice block C and breaks the balance between the ice blocks, thereby facilitating the flow of the ice block C. Thus, the smooth ice block C is taken in from the intake port 44.

  The intake port 44 is formed by cutting out a half of the circumference of the ice guide 42, and the axial opening width is set to be substantially the same as the interval P between the adjacent blade portions 48a, 48a. Therefore, the ice block C can be preferably taken into the ice guide 42 when the take-in port 44 faces the ice storage chamber 14. When the ice guide 42 rotates, the intake port 44 faces the ice storage chamber 14 every half circle, so that the ice block C is taken in every half circle. That is, the ice block C taken into the internal region (hereinafter referred to as the opening region) of the ice guide 42 facing the ice storage chamber 14 from the intake port 44 is transferred upward by the fins 48 as the ice guide 42 rotates. At the same time, when the intake port 44 faces the ice storage chamber 14 next time, the ice block C present in the opening region is transferred to the upper side (between adjacent blade portions 48a and 48a located on the discharge port 46 side). Therefore, the opening area is empty. Therefore, when the intake port 44 faces the ice storage chamber 14, the opening area is always empty, so that a stable amount of the ice block C can be taken in properly, and the ice block C Biting due to falling halfway is also prevented. Further, by providing the ice guide 42 with a time zone during which the ice block C is not taken in, there is room in the ice guide 42 and the ice block C can be smoothly transported without clogging.

  The opening edge 44a on the rear side in the rotation direction of the intake port 44 is rotated on the ice block C located on the rotation locus of the ice guide 42 falling into the ice guide 42 from the intake port 44. It is a surface which contacts with it. Here, the intake port 44 is formed with round bar steel at the opening edge 44a located on the rear side in the rotation direction, and has an R shape without a corner of the opening edge 44a. The load such as friction and catching with the opening edge 44a can be reduced, and the opening edge 44a can be reinforced. That is, when the ice guide 42 rotates and the opening edge 44a located on the rear side in the rotation direction approaches the wall portion located on the front side in the rotation direction in the installation recess 20, the ice block is pushed by the opening edge 44a having the R shape. Since C escapes, it is avoided that the ice block C is caught between the opening edge 44a and the wall portion. Therefore, at the intake port 44, rotation inhibition and noise generation due to the biting of the ice block C are prevented.

  The installation recess 20 into which the ice guide 42 is inserted corresponds to the inlet 44 of the ice guide 42 and projects above the ice guide 42 in an inclined lower end region located on the front side in the rotation direction of the ice guide 42. A flange portion 20a is formed apart from the outer peripheral surface of the ice guide 42. Since the pocket is widened by providing the flange portion 20a, the ice block C can be prevented from being bitten by being pushed by the opening edge 44a as the ice guide 42 rotates, and the ice block smoothly. C can be guided to the intake port 44 and preferably taken into the ice guide 42.

  By rotating and driving the stirring means 80, the ice block C is pushed toward the center of the ice storage chamber 14 to promote the flow of the ice block C. Thereby, blocking, arching, etc. which occurred near the bottom of the ice storage chamber 14 as the ice block C is carried out can be eliminated. Further, since the stirring ring 84 is formed in a spiral shape and has a smooth shape with no straight portion, resistance to the ice block C can be suppressed when the stirring ring 84 rotates.

  The ice guide 42 is held by the bearings 62 and 62 and the bearing 28, and is detachably connected to the drive shaft 58 of the motor 56 via the engagement member 64, so that the ice guide 42 can be easily removed. be able to. Accordingly, since the ice guide 42 and the ice storage chamber 14 can be easily cleaned, the sanitary condition can be suitably maintained.
