[0008] <Description of the embodiment-1> Hereinafter, a mode for carrying out the present invention (hereinafter, referred to as an "embodiment") will be described in detail with reference to the accompanying drawings. The same elements are designated by the same reference numerals throughout the description of the embodiment.

[0009] <Overall configuration of the wringer-1> Fig. 1 is a side view showing the wringer of this embodiment, Fig. 2 is a top view showing the wringer of this embodiment, Fig. 3 is a top view showing the fixed roller unit, and Fig. 4 is a top view showing the movable roller unit. In Figs. 1 to 6C, in order to show the positional relationship of the components, components that are actually hidden by other components and cannot be seen are also shown as appropriate.

[0010] <Overall configuration of the wringer-2> As shown in Figures 1 and 2, the wringer of this embodiment includes a fixed roller unit 1 to which a fixed roller 10 is rotatably attached, and a movable roller unit 2 to which a movable roller 20 facing the fixed roller 10 is rotatably attached.

[0011] <Overall configuration of the squeezer-3> The moving roller unit 2 is configured as a separate body from the fixed roller unit 1 and is separable from the fixed roller unit 1. The fixed roller unit 1 and the moving roller unit 2 each include a fixed roller 10 and a moving roller 20, and are both made of stainless steel.

[0012] <Configuration of fixed roller unit-1> As shown in Figures 1 to 3, the fixed roller unit 1 comprises a fixed roller 10, a shaft member 11 fixed to the fixed roller 10, a pair of side bases 12 arranged on the left and right of the shaft member 11 in Figure 3, and a bearing 13 that rotatably supports the shaft member 11.

[0013] <Configuration of fixed roller unit-2> The side base 12 includes a side guide 12A extending in the up-down direction in Fig. 3, and walls 12B and 12C extending in the left-right direction in Fig. 3, continuous with the side guide 12A. As shown in Fig. 3, the side guide 12A, the walls 12B and 12C are arranged to cover three surfaces of the outer periphery of the side base 12 when viewed from above. This prevents foreign matter from entering the fixed roller 10 side, for example, when the bearing 13 is damaged. Note that instead of the walls 12B and 12C, a wall surface that covers the entire outer periphery of the side base 12 may be provided.

[0014] <Configuration of fixed roller unit-3> The bearing 13 is attached to the bottom surface of the side base 12 via a mounting plate 14. The mounting plate 14 is attached to the bottom surface of the side base 12 via screws 14A serving as fasteners, and can be separated from the side base 12 by removing the screws 14A. Therefore, the fixed roller 10 can be separated from the fixed roller unit 1 by removing the screws 14A. Furthermore, the fixed roller 10 can be attached to and detached from the side base 12 by the screws 14A, without the need for tools.

[0015] <Configuration of fixed roller unit-4> As shown in Figs. 1 to 3, a pressing block 15 is attached to the bottom surface of the side base 12. A cam surface 15a that is inclined downward to the right in Fig. 1 is formed on the pressing block 15. Furthermore, the tip of a male screw 15b that screws into the wall portion 12C of the side base 12 abuts against the pressing block 15 from the left in Fig. 1, and the position of the pressing block 15 (the position in the left-right direction in Fig. 1) can be adjusted by turning the male screw 15b. The pressing block 15 is supported on the side base 12 so as to be slidable in the left-right direction in Fig. 1.

[0016] <Configuration of fixed roller unit-5> Further, a pin 16 is attached to the side guide 12A of the side base 12 near the shaft member 11, with which a side frame 22 (described later) comes into contact. <Configuration of fixed roller unit-6> 1 and 3, the side guide 12A has a protruding portion 12p (FIG. 1) that protrudes upward on the left side of FIG. 1. The upper end of the protruding portion 12p is formed with recesses 17A and 17B (FIGS. 1 and 3) that are recessed downward.

[0017] <Configuration of moving roller unit-1> As shown in Fig. 1, Fig. 2 and Fig. 4, the moving roller unit 2 includes a moving roller 20, a shaft member 21 fixed to the moving roller 20, a pair of side frames 22 arranged on the left and right of the shaft member 21 in Fig. 4, a bearing 23 that rotatably supports the shaft member 21, and two bars 24, 25 that are spanned between the pair of side frames 22. As shown in Fig. 2, the side frame 22 is guided by a side guide 12A, and the moving roller unit 2 is movable in the up-down direction in Fig. 2. The side frame 22 abuts against the side guide 12A, thereby restricting the movement of the moving roller unit 2 in the left-right direction in Fig. 2. In addition, the shaft member 21 and the bars 24, 25 come into contact with the upper end of the side guide 12A, thereby supporting the moving roller unit 2 from below.

[0018] <Configuration of moving roller unit-2> 1, the bars 24, 25 are attached between the pair of side frames 22 at a distance therebetween, thereby firmly fixing the pair of side frames 22 and functioning as a gripping portion to be operated by hand. As described above, the bars 24, 25, together with the shaft member 21, also function as a member supporting the movable roller unit 2 by contacting the upper end of the side guide 12A.

[0019] <Configuration of moving roller unit-3> 4, threaded portions 24A and 25A are provided on the bars 24 and 25, respectively, and nuts 24B and 25B are screwed into the threaded portions 24A and 25A, respectively, whereby the bars 24 and 25 are attached between the pair of side frames 22. The bars 24 and 25 are formed with engagement portions (not shown) on the right ends in FIG. 4 that engage with the side frame 22.

[0020] <Configuration of moving roller unit-4> By attaching the bars 24, 25 to the pair of side frames 22 with nuts 24B, 25B, the interval (the interval in the left-right direction in FIG. 4) between the pair of bearings 23 attached to the pair of side frames 22 is also kept constant. As a result, the moving roller 20 is rotatably and firmly supported at a predetermined position relative to the side frames 22. In addition, the structure in which the pair of side frames 22 are fixed by the bars 24, 25 allows the moving roller unit 2 to be lightweight and easy to handle. Furthermore, by appropriately setting the interval (the interval in the up-down direction in FIG. 4) between the two bars 24, 25, the bars 24, 25 can be easily grasped with one hand, improving the workability of using the moving roller unit 2. In addition, the moving roller unit 2 can be easily attached to and detached from the fixed roller unit 1.

[0021] <Configuration of moving roller unit-5> In addition, the nuts 24B and 25B serving as fasteners can be attached and detached manually without using tools. Therefore, by manually removing the nuts 24B and 25B, the pair of side frames 22 can be separated from each other, and thus the movable roller 20 can be easily separated from the movable roller unit 2.

[0022] <Status of moving roller unit-1> As described above, the moving roller unit 2 is configured as a separate unit from the fixed roller unit 1, and the moving roller unit 2 can be moved by gripping it with a hand. In this embodiment, the moving roller unit 2 can be selectively placed on the fixed roller unit 1 in at least two states: a first state in which the moving roller 20 faces the fixed roller 10, and a second state in which the moving roller 20 is separated from the fixed roller 10.

[0023] <Status of moving roller unit-2> The first state is, for example, the state shown in Figures 1 and 2. In the state shown in Figures 1 and 2, the moving roller unit 2 is in a state in which the shaft member 21 and the bars 24 and 25 contact the upper end of the side guide 12A as shown in Figure 1.

[0024] <Status of moving roller unit-3> 1, the movable roller 20 is in contact with the fixed roller 10, or the movable roller 20 is slightly separated to the left from the fixed roller 10. At this time, the end 22B (FIG. 1) of the side frame 22 is in contact with the pressing block 15, or the end 22B of the side frame 22 is slightly separated to the right from the pressing block 15.

[0025] <Status of moving roller unit-4> In this embodiment, in the first state, when no force other than gravity is applied to the moving roller unit 2, the shaft member 21 fixed to the moving roller 20 is configured to contact the upper end of the side guide 12A in Fig. 1 together with the bars 24 and 25. This makes it possible to prevent the moving roller 20 from rotating accidentally or the free moving roller 20 from continuing to rotate indefinitely due to the frictional force generated by the shaft member 21 contacting the side guide 12A.

[0026] <Status of moving roller unit-5> Next, the second state is, for example, the state shown in Fig. 5. Fig. 5 is a side view showing the state in which the movable roller is separated from the fixed roller.

[0027] <Status of moving roller unit-6> In the state shown in FIG. 5, the bar 25 of the moving roller unit 2 engages with the recess 17A of the side guide 12A, and the shaft member 21 contacts the upper end of the side guide 12A. At this time, the side frame 22 is separated from the pressing block 15. In this state, the moving roller unit 2 is locked by the bar 25 engaged with the recess 17A, and the moving roller unit 2 does not slip down downward or to the right in FIG. 5. Note that the state in which the bar 25 of the moving roller unit 2 engages with the recess 17B of the side guide 12A can be appropriately selected. In this case, the distance between the fixed roller 10 and the moving roller 20 can be further increased.

[0028] <Status of moving roller unit-7> When the movable roller unit 2 is in the state shown in Fig. 1, if the bars 24, 25 are grasped and pulled up by hand, the movable roller unit 2 rotates in an arc in the clockwise direction in Fig. 1 with the shaft member 21 remaining in contact with the upper end of the side guide 12A, and the end 22B (Fig. 1) of the side frame 22 is released by being released from the pressing block 15. At this time, because the end 22B of the side frame 22 is a convex curved surface, the end 22B of the side frame 22 can be released smoothly.

[0029] <Status of moving roller unit-8> Next, the bar 24 is pushed leftward in FIG. 1 so that the bar 25 engages with the recess 17A of the side guide 12A, thereby achieving the state shown in FIG.

[0030] <Process 1: Squeezing out the contents of the bag> Next, a process for squeezing the contents of a bag using the squeezing machine of this embodiment will be described with reference to Figs. 6 to 6D.

[0031] <Process 2: Squeezing out the contents of the bag> Figure 6 is a side view showing the state when a bag is set, Figure 6A is a side view showing the state when the moving roller unit is moving, Figure 6B is a side view showing the state when a bag is pulled out, Figure 6C is a side view showing the position of the moving roller unit when a bag is pulled out, and Figure 6D is a side view showing the position of the side frame when a bag is pulled out.

[0032] <Process 3: Squeezing out the contents of the bag> First, as shown in Fig. 6, the movable roller unit 2 is set in the state shown in Fig. 5, and the lower part of the bag 90 is cut between the movable roller 20 and the fixed roller 10. At this time, a part of the contents of the bag 90 falls due to gravity and is contained in the container 100.

[0033] <Process 4: Squeezing out the contents of the bag> Next, when bar 25 of moving roller unit 2 is lifted by hand, moving roller unit 2 rotates clockwise in Fig. 6 with shaft member 21 still in contact with the upper end of side guide 12A, and bar 25 is released from recess 17A. Furthermore, when bar 24 and / or bar 25 are grasped by hand and pulled to the right in Fig. 6 and moved downward, shaft member 21 slides to the right along the upper end of side guide 12A, resulting in the state shown in Fig. 6A.

[0034] <Process 5: Squeezing out the contents of the bag> In the state of Fig. 6A, the end 22B of the side frame 22 abuts against the cam surface 15a of the pressing block 15, and the shaft member 21 contacts the upper end of the side guide 12A. In this state, the side frame 22 acts as a cam follower, and the shaft member 21 slides to the right along the upper end of the side guide 12A, and the moving roller unit 2 moves to the right in Fig. 6A. As a result, the state of Fig. 6B is reached, that is, the shaft member 21 and the bars 24 and 25 contact the upper end of the side guide 12A.

[0035] <Process 6: Squeezing out the contents of the bag> In the state of Fig. 6B, the movable roller unit 2 is housed between the pressing block 15 and the fixed roller 10, so that the position in the left-right direction in Fig. 6B is determined. Also, the gravity acting on the movable roller unit 2 causes the shaft member 21 and the bars 24, 25 to come into contact with the upper end of the side guide 12A, so that the position in the up-down direction is determined. The clearance between the fixed roller 10 and the movable roller 20, which is determined by the distance between the pressing block 15 and the fixed roller 10 (the distance in the left-right direction in Fig. 6B) and the dimensions of the movable roller unit 2, can be adjusted as needed by adjusting the position of the pressing block 15 with the male screw 15b.

[0036] <Process 7: Squeezing out the contents of the bag> Next, in the state of Fig. 6B, when bag 90 is held with both hands and pulled in the direction of arrow 91, the bag 90 passes between rotating fixed roller 10 and movable roller 20, whereby the contents are squeezed out and the contents remaining in bag 90 are stored in container 100. At this time, a leftward force resulting from the pressure of the contents and an upward force resulting from the upward movement of bag 90 are applied to movable roller 20, and these forces act as a force pushing movable roller unit 2 to the left in Fig. 6B and a moment tending to rotate it counterclockwise.

[0037] <Process 8: Squeezing out the contents of the bag> However, as for the force pushing the moving roller unit 2 to the left, as shown in Figures 6C and 6D, the end portion 22B of the side frame 22 abuts against the pressing block 15, so that the movement of the moving roller unit 2 to the left is restricted. Therefore, the clearance between the fixed roller 10 and the moving roller 20 is appropriately maintained.

[0038] <Step 9: Squeezing out the contents of the bag> Furthermore, when the moment trying to rotate the moving roller unit 2 counterclockwise overcomes gravity and the moving roller unit 2 starts to rotate counterclockwise, the end 22A (FIG. 6D) of the side frame 22 immediately comes into contact with the pin 16, restricting the rotation of the moving roller unit 2. Furthermore, when the end 22A of the side frame 22 comes into contact with the pin 16, the shaft member 21 fixed to the moving roller 20 moves away from the upper end of the side guide 12A, generating a clearance Dc (FIG. 6D). This allows the moving roller 20 to rotate smoothly. At this time, only the bar 25 comes into contact with the upper end of the side guide 12A.

[0039] <Effects of the Invention-1> The effects of this embodiment will be described below.

[0040] <Effects of the invention-2> In this embodiment, the moving roller unit 2 can be easily separated from the fixed roller unit 1 by hand. Furthermore, the fixed roller 10 can be separated from the fixed roller unit 1, and the moving roller 20 can be separated from the moving roller unit 2 without using tools. Therefore, the fixed roller 10, the moving roller 20, and each part of the device can be easily disassembled, washed, and sterilized. Furthermore, since the side guide 12A, the wall portion 12B, and the wall portion 12C that cover the periphery are provided on the side base 12, it is possible to prevent foreign matter from entering the sides of the fixed roller 10 and the moving roller 20 even if a part breaks down. Therefore, it is also suitable when the contents of the bag are food. Furthermore, the number of parts is small, and disassembly, washing, and sterilization can be easily performed.

[0041] <Effects of the Invention-3> Since the movable roller unit 2 can move easily, the number of steps required to squeeze out the contents is reduced, and the bag can be easily sandwiched between the rollers. In addition, the use of bearings allows the fixed roller 10 and the movable roller 20 to rotate smoothly. Therefore, no force is required even for highly viscous contents.

[0042] <Effects of the Invention-4> Since the clearance between the fixed roller 10 and the movable roller 20 can be finely adjusted, the amount of material remaining on the bag after squeezing can be reduced.

[0043] <Effects of the Invention-5> Since no motor or other power source is required, there are virtually no breakdowns and no maintenance is required. In addition, since no power source is used, the safety during operation is high.

[0044] <Contents Description-1> In the present invention, the viscous contents are not limited, and the present invention can be applied to contents other than food. In the case of food, examples include syrup, mayonnaise, mizuame, tomato ketchup, strawberry jam, hand cream, mustard, paste, etc. Although the viscosity of the contents is not particularly limited, the present invention is particularly useful for contents with high viscosity (for example, contents with a viscosity of 10 Pa·s or more).
