Embodiment 1
FIG. 1 is a view showing an ice-sea water tank 1 in which an ice piece forming apparatus 100 according to Embodiment 1 of the present invention is used. As shown in FIG. 1, the ice sea water tank 1 is in the shape of a rectangular parallelepiped (rectangle).

  Furthermore, on both sides of the ice-sea water tank 1 in the longitudinal direction, rails for a pulling car 2 are provided at positions substantially the same height as the opening of the ice-water tank 1. The towing vehicle 3 is a vehicle capable of traveling in the longitudinal direction of the ice sea water tank 1 along the towing vehicle rail 2.

  Further, the aquarium water 4 is put on the ice sea water tank 1, and the ice piece forming device 100 is attached to the towing vehicle 3. The ice piece forming apparatus 100 can be rolled by the towing vehicle 3 and travel in the longitudinal direction of the ice sea water tank 1. Hereinafter, in the length direction of the ice sea water tank 1, the moving direction in which the ice piece forming device 100 is rolled and moved by the pulling car 3 is referred to as a traveling direction.

  FIG. 2 is a schematic view of the ice chip production apparatus 100 viewed from the front side according to the first embodiment of the present invention. Here, the front side is described as the front side in the traveling direction when the ice pieces are formed. The ice piece forming apparatus 100 is an apparatus attached to the towing wheel 3 when forming an ice piece. The ice piece forming apparatus 100 has a plurality of ice cutters 110 serving as cutting tools, a fixing member 120 and a loading jig 130.

  The cutting edges of the plurality of ice cutters 110 are directed in one direction in the traveling direction, and are attached to the fixing member 120 in parallel in the width direction of the ice ocean water tank 1. Hereinafter, the width direction of the ice sea water tank 1 is demonstrated as what is a sequence direction of the ice cutter 110. FIG. The ice cutter 110 cuts the ice plate made on the surface of the ice-sea water tank 1 into strips and divides the ice plate into pieces by moving the ice-sea water tank 1 by the ice piece forming apparatus 100 pulled by the pulling car 3. Cutting tool. Although the material which comprises the ice cutter 110 is not specifically limited, For example, aluminum is used.

  The fixing member 120 is a member for fixing the plurality of ice cutters 110 and the loading jig 130 so as not to move with respect to the pulling wheel 3. The fixing member 120 has a support rod 121 and a collar 122. The fixing member 120 has two support rods 121. The support bar 121 is a beam. For example, two support rods 121 are respectively passed through two through holes of the ice cutter 110, and the ice cutter 110 is supported so as not to move in the traveling direction and in the vertical direction. The loading jig 130 is similarly supported.

  FIG. 3 is a diagram for explaining the adjustment of the distance between the ice cutters 110 according to Embodiment 1 of the present invention. The ice piece forming device 100 according to the first embodiment can adjust the interval of the arrangement of the ice cutters 110. When passing the ice cutter 110 to the support rod 121, the tubular collar 122 is passed between at least the ice cutters 110 to sandwich and fix the ice cutters 110. The collar 122 serves as a stopper that defines the width of the ice cutter 110 in the arrangement direction of the ice cutters 110. Further, the collar 122 is an adjusting tool capable of adjusting the distance between the ice cutters 110. For example, colors 122 having different lengths are prepared. Then, by interposing the collar 122 corresponding to the width of the ice pieces to be made between the ice cutters 110, the distance between the ice cutters 110 and the width of the ice pieces can be adjusted. Here, it is not necessary to make the lengths of all the collars 122 the same and cut the ice plate at equal intervals between the ice cutters 110. In addition, as long as the distance between the ice cutters 110 can be defined, it is not limited to the collar 122.

  FIG. 4 is a view showing an outline of the ice piece production device 100 as viewed from the back side according to the first embodiment of the present invention. Here, in the advancing direction of the ice chip creation apparatus 100 at the time of ice chip creation, the surface which becomes a rear side is demonstrated as a back surface. The loading jig 130 is installed rearward of the cutting edge of the ice cutter 110 with respect to the traveling direction. The loading jig 130 divides the ice plate cut by the ice cutter 110 along a direction intersecting the traveling direction of the ice cutter 110 (for example, a direction orthogonal to the traveling direction) Is a jig to create At this time, the load jig 130 splits and divides the ice plate in such a manner that a force is applied downward (toward the bottom of the ice sea water tank 1) to the ice plate of the cut portion. Create

  The loading jig 130 has a mounting portion 131, a loading position setting portion 132, an angle setting portion 133, and a loading plate 134. The attachment portion 131 has two through holes similarly to the ice cutter 110. Then, it is passed through the support rod 121, and the loading jig 130 is attached so as not to move in the traveling direction and in the vertical direction.

  The loading plate 134 is a plate fixed at an angle so as to be oblique to the traveling direction. Here, the angle formed by the loading plate 134 is a depression angle. Hereinafter, the depression angle which the loading plate 134 makes with the traveling direction will be described as an angle. The material of the loading plate 134 is not particularly limited, and for example, artificial wood such as chemical wood is used.

  FIG. 5 is a view for explaining the front-rear loading position and the angle setting of the loading plate 134 according to the first embodiment of the present invention. An angle setting unit 133 is installed on the loading plate 134. The angle setting unit 133 fixes, for example, the loading plate 134 at an angle set by a worker or the like. The angle setting unit 133 has a fastener. The loading plate 134 is pivoted about the fastener, and the fastener is fastened to the adjustment rod of the loading position setting unit 132 at a set angle to fix the loading plate 134. The length of the ice pieces can be adjusted by the angle of the loading plate 134 set in the angle setting unit 133.

  The loading position setting unit 132 sets the front and rear loading positions. By setting the front and rear loading positions, the lengths of the cutting edge (tip portion) of the ice cutter 110 and the loading plate 134 are set. The loading position setting unit 132 has an adjusting rod. The adjusting rod has a plurality of holes aligned in the traveling direction, and can fasten the fastener of the angle setting portion 133. By adjusting the position of the hole for holding the fastener, the front-rear loading position in the angle setting unit 133 can be changed. Thereby, the setting of the length of the blade tip (tip end portion) of the ice cutter 110 and the loading plate 134 can be performed. Then, the length of the ice piece can be adjusted by the length of the cutting edge (tip portion) of the ice cutter 110 and the loading plate 134 set in the loading position setting unit 132. However, the adjustment method is not limited to this method.

  The angle of the loading plate 134 is not particularly limited, but here, as an example, the angle formed with the traveling direction is set to 150 °, for example. For example, if the angle is too shallow or too deep, the force applied in the downward direction becomes small, and the ice plate 200 becomes difficult to break. Also, for example, the depth from the water surface of the end of the loading plate 134 changes depending on the angle. The broken ice pieces flow through the water to the rear side of the ice piece forming device 100 through the end of the load plate 134. When the end of the loading plate 134 is at a deep position from the water surface, the broken ice pieces can not get out of the end of the loading plate 134 and are caught on the loading plate 134, and after the loading plate 134 Because the fluid does not flow to the side, it may prevent the formation of continuous ice pieces. Therefore, it is better to set the angle of the loading plate 134 in a balanced state of shallow depth. For this reason, it is better to adjust the length of the ice pieces by setting the front-rear loading position by the loading position setting unit 132 rather than setting the angle by the angle setting unit 133.

  FIGS. 6-9 is a figure explaining the procedure of the production method of an ice piece using the ice piece production apparatus 100 based on Embodiment 1 of this invention. In preparation for production, the ice chip production device 100 is attached to the towing wheel 3. Further, for example, the tank water 4 is frozen by, for example, cooling the room where the ice sea water tank 1 is installed. Then, an ice plate 200 is put on the surface of the ice sea water tank 1. Although not particularly limited, the thickness of the ice plate 200 is about 1.5 cm.

  Then, the towing vehicle 3 moves in the traveling direction (the longitudinal direction of the ice sea water tank 1). As shown in FIG. 6, with the movement of the towing vehicle 3, the ice piece forming device 100 moves in the traveling direction, and the ice cutter 110 ices the ice plate 200 made on the water surface of the ice ocean water tank 1 in the traveling direction Cut along. The tip of the ice plate 200 moves relative to the ice chip producing device 100 in the direction opposite to the traveling direction of the ice chip producing device 100.

  When the cutting by the ice cutter 110 proceeds, as shown in FIG. 7, the tip of the cut ice plate 200 contacts the loading plate 134 of the loading jig 130. The loading plate 134 has a slope with respect to the ice plate 200, and the tip of the cut ice plate 200 moves along the slope of the loading plate 134. At this time, the position of the ice plate 200 corresponding to the position of the cutting edge of the ice cutter 110 (the other end portion cut in the ice plate 200) serves as a fulcrum, and the tip of the ice plate 200 serves as a force point. The downward bending force is applied.

  As the tip of the ice plate 200 moves on the slope of the loading plate 134, the downward force increases, and when the bend becomes large, the ice plate 200 is broken from the fulcrum portion, as shown in FIG. A piece is created. Here, the ice plate 200 is applied so that the downward force is equalized. For this reason, the cut portion of the ice plate 200 is broken along the alignment direction, and the shape of the ice pieces to be produced is almost a rectangular solid and has a neat shape. When the above steps are continued, as shown in FIG. 9, ice pieces can be continuously formed as the ice piece forming apparatus 100 moves in the traveling direction.

  As described above, according to the first embodiment, the ice cutter 110 cuts the ice plate 200 in the traveling direction by moving the ice sea water tank 1 by the ice piece forming apparatus 100, and the ice plate 200 is further cut. By placing the load plate 134 and applying a bending force, the ice plates 200 are broken in the side-by-side direction to create ice pieces, so even if the operator does not break the ice pieces, automatic Ice pieces can be created. For example, rather than creating an ice piece by applying an impact by dropping an ice plate or the like, the ice piece is created by cutting and breaking it, so that the shape, size, etc. are almost uniform. Ice pieces can be created.

  In addition, since the ice chip creating apparatus 100 includes the loading position setting unit 132 and the angle setting unit 133, the length of the ice chip to be created can be adjusted. Moreover, the width | variety of the ice piece to produce can be adjusted by adjusting the space | interval of the ice cutter 110 with the color | collar 122. FIG.

Second Embodiment
In the above embodiment, the loading plate 134 has been described as being flat. Although it is convenient for the loading plate 134 to be flat in view of the downward force applied, the retention of broken ice pieces, and the like, for example, the loading plate 134 may be curved.

  Further, although not particularly described in the embodiment described above, at least one of the ice piece forming device 100 and the ice plate 200 shakes in the vertical direction when the ice piece forming device 100 is performing ice piece forming. Sometimes. The positional relationship between the loading plate 134 and the cut ice plate 200 may not be determined due to vertical shaking, and the ice pieces 200 may have different lengths due to different timings such as the ice plate 200 being broken.

  Therefore, for example, the detecting device may be installed in the ice piece forming device 100, and the ice piece forming device 100 may be moved while adjusting the position of the ice piece forming device 100 with respect to the ice plate 200 in the vertical direction.

  In the above-described embodiment, by moving the ice piece generating apparatus 100, the bending force can be automatically applied from the loading jig 130 to the ice plate 200. Without limiting to this, an apparatus for driving the ice plate 200 so as to apply a force to fold the ice plate 200 may be installed in the ice piece forming device 100.

  Also, in the above-described embodiment, although description has been made on the assumption that ice pieces used for brush ice channel test and rable ice test are created, the application of the ice pieces created according to the present invention is limited It is not a thing.
