Description

  2. Description of the Related Art Conventionally, in hospitals, nursing homes, etc., many foods, mixer meals, and the like that are thick for patients (particularly elderly people) who have a poor eating function among patients and residents are provided.

  The size and degree of softness of ingredients vary depending on the ability of the patient and residents to chew and swallow, and people with high chewing / swallowing ability can eat even foods with low thickness (low viscosity). A person who can eat but has low ability of chewing / swallowing function needs to adjust the thickening according to the degree of the ability.

  By the way, each food maker provides foods having an optimum degree of thickening (viscosity and hardness) according to the degree of difficulty in chewing and swallowing.

  In addition to sensory evaluation, each food manufacturer performs measurement of the degree of thickness by the concentric circle method (for example, see Patent Document 1), measurement of the degree of thickness by a dedicated device (for example, see Patent Document 2), and the like.

  Among them, the thickness measurement by the concentric circle method of Patent Document 1 uses, for example, an equidistant concentric circle and a flat plate (spread meter) in which straight lines are drawn in six directions every 60 degrees from the center to the circumference. Done.

  The distance from the center is marked at the point where the straight line and circle of this spread meter intersect, and a predetermined amount of thickened food, which is the object to be measured, is placed in the center of the spread meter at a specific temperature within a specific time. Investigate the spreading state (condition) of thick food and measure its thickness.

  In addition, the measurement of the degree of thickening by the thickness measuring device of Patent Document 2 is performed by filling the thickened food between the cone and the flat plate member, and driving the motor to rotate the rotating shaft. Resistance due to thickening is applied as a tensile load to the coil spring, and accordingly, the coil spring is stretched, and a twist corresponding to the deflection of the coil spring is generated between the two disks.

  Therefore, when an arc-shaped electric resistor is attached to one disc, a pickup is attached to the other disc, and a constant voltage is applied to the electric resistor from the outside, the tip of the pickup is in contact with the electric resistor. Moving.

  Therefore, by reading the voltage output from the pickup, it is possible to detect the angle of twist between the two disks, and by calculating the torque applied to the cone based on this angle of twist, Measure the thickness.

  The above-described motor 21 is constituted by, for example, a DC motor and a speed reducer. The housing 22 is on the upper side, and the rotating shaft 23 protruding from the housing 22 is on the lower side. A rotating shaft 23 is rotatably supported by a bearing 18 at the center of the bottom plate portion 13a. That is, the motor 21 is rotatably supported with respect to the container body 12 and the bottom plate part 13.

  The cylindrical casing 22 of the motor 21 is provided (attached) with a stretching member 24 that protrudes radially outward from a predetermined position on the circumferential surface, and the left side of the stretching member 24 in plan view. A pointer 25 protruding outward in the radial direction is provided at a position separated by a predetermined distance in the circumferential direction.

For example, the rod-shaped body 31 having a circular cross-section has a part (part) that enters the thickened food F. ), A plurality of (for example, two) blades 33 as resistors that protrude in the radial direction are attached (installed) in the circumferential direction.

  The rod-shaped body 31 described above functions as a thickness measuring body when the thickening degree of the thick food F is measured, and also functions as a stirring (auxiliary) body for stirring the thick food F and the like.

  Further, the blade 33 (resistor) functions as a thickness measuring body when measuring the thickness of the thick food F and also functions as a stirring (main) body for stirring the thick food F and the like.

  On the upper surface of the bottom plate portion 13a of the lid 13 constituting the container 11, a support bar (support body) 41 protruding upward, and a tension that comes into contact with the upper end of the support bar 41 from the right side in a plan view.

  A coil spring (elastic body) 46 is disposed between a portion (portion) of the tension member 24 positioned radially outward from the stopper rod 44 and a portion (portion) of the tension adjusting screw 43 on the stopper rod 44 side. The tension member 24 comes into contact with the stopper bar 44, and the pointer 25 indicates a predetermined value (predetermined degree of thickness) of the scales 45A and 45B.

  The coil spring 46 is stretched between a portion (part) of the tension member 24 positioned radially inward of the stopper bar 44 and a portion (part) on the stopper rod 44 side of the tension adjusting screw 43. May be.

  A display unit 51 is configured by the above-described pointer 25 and the scales 45A and 45B.

  The motor 21 is connected to a battery (not shown) accommodated in the lid 13 by wiring (not shown).

  Next, stirring of the thick food F will be described.

  First, the thick food F is put into the container main body 12 and the opening of the container main body 12 is closed with the lid 13, so that the rod-shaped body 31 and the blade 33 are inserted into the thick food F.

  Then, when the stirring switch 15 is operated to be turned on and the motor 21 is driven, in FIG. 2 and FIG. 3, the rotating shaft 23 rotates counterclockwise, for example, at a constant stirring speed of 1000 rpm to 2000 rpm. As a result, the rod-shaped body 31 and the blades 33 also rotate counterclockwise.

  As described above, when the rod-shaped body 31 and the blades 33 are rotated counterclockwise, the motor 21 is rotated clockwise by the resistance of the thickening food F received by the rod-shaped bodies 31 and the blades 33, whereby the stretching member 24 is stopped. Since the motor 21 does not rotate clockwise in contact with the rod 44, the thickened food F in the container 11 is stirred by the rod-shaped body 31 and the blade 33.

  Then, when the stirring switch 15 is operated to turn off after a predetermined time, the motor 21 is stopped and stirring of the thick food F in the container 11 is completed.

  Next, the measurement of the degree of thickening of the thick food F will be described.

  First, the thick food F is put into the container main body 12 and the opening of the container main body 12 is closed with the lid 13, so that the rod-shaped body 31 and the blade 33 are inserted into the thick food F.

  Then, for example, when the measurement switch 16A is turned on by operating the measurement switch 16A to light the measurement switch 16A in a predetermined color and drive the motor 21, in FIG. 2 and FIG. 3, the rotating shaft 23 is rotated clockwise, for example, 50 rpm. By rotating (turning) at a constant measurement speed of ˜120 rpm, the rod-shaped body 31 and the blades 33 are also rotated (turned) in the clockwise direction.

  As described above, when the rod-shaped body 31 and the blade 33 rotate (rotate) in the clockwise direction within the thickened food F, the reaction force (rotational moment) according to the degree of thickening of the thickened food F received by the rod-shaped body 31 and the blade 33 ( 2 and 3, the motor 21 rotates counterclockwise in FIGS. 2 and 3 due to the counterclockwise force).

  As described above, when the motor 21 rotates counterclockwise, the coil spring 46 extends (deforms) in accordance with the degree of thickening of the thickened food F when the rod-shaped body 31 and the blade 33 are received, and the motor 21 moves counterclockwise. The rotation stops at a predetermined position, and the pointer 25 indicates the value (thickness) of the scale 45A having the same color as that of the measurement switch 16A that is lit.

  Therefore, by reading the scale 45A indicated by the pointer 25, the degree of thickening of the thick food F can be obtained.

  Then, when the measurement switch 16A is operated and turned off after a predetermined time, the motor 21 is stopped, the measurement switch 16A is also turned off, and the rotation (rotation) of the rod-shaped body 31 and the blade 33 is also stopped. 21 is rotated by the urging force of the coil spring 46 so as to be returned in the clockwise direction to the position where the tension member 24 contacts the stopper bar 44.

  As described above, in the state where the measurement switch 16A is operated to rotate the motor 21 (rotating shaft 23), the thickening of the thickened food F, the number of rotations of the rod-like body 31 and the blade 33 for measuring the thickening Does not fit and the pointer 25 does not point within the range of the scale 45A (when the pointer 25 points outside the range of the scale 45A), the measurement switch 16B is operated to switch the measurement range of the degree of throttling. When the measurement switch 16A is turned on and the measurement switch 16B is turned on in a different color from the measurement switch 16A and the measurement switch 16A is turned off and the motor 21 is driven, the rotating shaft 23 in FIGS. Is rotated (rotated) in a clockwise direction at a constant measurement rotational speed of, for example, 120 rpm to 200 rpm, so that the rod-shaped body 31 and the blades 3 also rotates in the clockwise direction (rotation).

  As described above, when the rod-shaped body 31 and the blade 33 rotate (rotate) in the clockwise direction within the thickened food F, the reaction force (rotational moment) according to the degree of thickening of the thickened food F received by the rod-shaped body 31 and the blade 33 ( 2 and 3, the motor 21 rotates counterclockwise in FIGS. 2 and 3 due to the counterclockwise force).

  As described above, when the motor 21 rotates counterclockwise, the coil spring 46 extends (deforms) in accordance with the degree of thickening of the thickened food F when the rod-shaped body 31 and the blade 33 are received, and the motor 21 moves counterclockwise. The rotation stops at a predetermined position, and the pointer 25 indicates the value (thickness) of the scale 45B having the same color as that of the measurement switch 16B that is lit.

  Therefore, by reading the scale 45B indicated by the pointer 25, the degree of thickening of the thick food F can be obtained.

  Then, when the measurement switch 16B is operated and turned off after a predetermined time, the motor 21 is stopped, the measurement switch 16B is also turned off, and the rotation (rotation) of the rod-shaped body 31 and the blade 33 is also stopped. 21 is rotated by the urging force of the coil spring 46 so as to be returned in the clockwise direction to the position where the tension member 24 contacts the stopper bar 44.

  As described above, consideration will be given to the fact that the scales 45A and 45B indicated by the pointer 25 become the thickening degree of the thick food F.

The output of the motor 21 when the motor 21 (rotating shaft 23) is rotating at a constant rotation speed (rpm) is P (W), the torque of the motor 21 at that time is T (Nm), and the motor 21 ( If the relationship value between the rotation speed (rpm) and the torque (Nm) of the rotation shaft 23) is n,
P = (2π / 60) × T × n (1)
(Equation is established)
T = (60 / 2π) × (P / n) (2)
And can be transformed.

  From equation (2), it can be seen that the rotational speed (rpm) of the motor 21 (rotating shaft 23) affects the torque T (the position at which the pointer 25 points to the scales 45A and 45B).

  Therefore, by reading the scales 45 </ b> A and 45 </ b> B indicated by the pointer 25, the thickening degree of the thick food F can be obtained.

  From the above, it is important to control the rotational speed of the motor 21 (rotating shaft 23) to be constant, and in the consistency measuring device of the present invention, the motor 21 (rotating shaft 23) is controlled to a constant rotational speed arbitrarily set. In addition, the measurement accuracy of the degree of thickness (torque) is improved.

  Next, tension adjustment of the coil spring 46 will be described.

  In FIG. 3, the knurled nut 42 is moved away from the support bar 41 and the tension adjusting screw 43 is rotated so that the coil spring 46 is not twisted even if the tension adjusting screw 43 is rotated, and the stopper bar 44 of the tension adjusting screw 43 is rotated. After increasing the protruding length from the knurled nut 42 in the direction, the knurled nut 42 is brought into contact with the support rod 41, whereby the tension (biasing force) of the coil spring 46 can be adjusted to be weak.

  Further, in FIG. 3, the nut 42 with knurling is separated from the support bar 41 and the tension adjusting screw 43 is rotated so that the coil spring 46 is not twisted even if the tension adjusting screw 43 is rotated. After shortening the protruding length from the knurled nut 42 in the direction of the rod 44, the tension (biasing force) of the coil spring 46 can be strongly adjusted by bringing the knurled nut 42 into contact with the support rod 41.

  As described above, according to the first embodiment of the present invention, the extension amount (deformation amount) of the coil spring 46 is displayed on the display unit 51 as the degree of thickening of the thickened food F. Therefore, the configuration is simple and the manufacturing is inexpensive. And the thickness can be accurately measured.

  Moreover, since the rod-shaped body 31 has the blade | wing 33, the thick food F etc. can be stirred.

  Also, when the thick food F is stirred and when the thickness of the thick food F is measured, the rotation direction of the motor 21 (rotary shaft 23) is opposite, and the rotation 23 axis of the motor 21 is Since the stopper rod 44 for stopping the rotation of the housing 22 of the motor 21 is provided when rotating so as to stir the needle 25, the pointer 25 does not swing during stirring, and the pointer 25 swings during measurement, and the scale 45A, Since 45B is instructed and the fatigue of the coil spring 46 when the thickened food F is agitated can be avoided, the life of the coil spring 46 can be lengthened and the measurement accuracy of the thickness can be maintained long.

  Moreover, since the tension of the coil spring 46 can be adjusted, the zero point of the display unit 51 can be corrected, the manufacturing variation of the coil spring 46 and the tension can be corrected due to the secular change of the coil spring 46, and the degree of thickness can be accurately measured. And can be displayed on the display unit 51.

  Further, since the display unit 51 is configured by the pointer 25 and the scales 45A and 45B, the configuration can be simplified.

  Further, since the measurement range of the degree of thickening can be switched, it is possible to measure the degree of thickness in a wide range.

  In addition, since the scales 45A and 45B indicated by the pointer 25 are made to correspond to the measurement switches 16A and 16B, erroneous measurement of the degree of thickening can be avoided.

  FIG. 4 is an explanatory view showing an essential part of a thickness measuring apparatus according to a second embodiment of the present invention, a view corresponding to FIG. 2, and FIG. 5 is an explanatory view showing a mainspring spring (spiral spring: elastic body). 4 is a view corresponding to an enlarged side view seen from the direction of arrow B in FIG. 4, FIG. 6 is an explanatory view showing a tension adjusting mechanism of a mainspring spring (spiral spring: elastic body), and is a cross-sectional view taken along the line CC in FIG. It is a figure corresponding, The same code | symbol is attached | subjected to the part equivalent to the part shown in FIGS. 1-3, or the part shown in FIGS. 1-3, and the description is abbreviate | omitted.

  The thickness measuring device of the second embodiment is different from the thickness measuring device of the first embodiment in that a coil spring (elastic body) 46 is a mainspring spring (spiral spring: elastic body) 63 and a coil. This is because the tension adjusting mechanism is changed in accordance with the spring 46 being the mainspring spring 63.

  That is, on the upper surface of the bottom plate portion 13a, a rotating member 61 as a tension adjusting mechanism that rotates around the bearing 18 (rotating shaft 23), and a tension adjustment that fixes the rotation of the rotating member 61. A fixing screw (fixing member) 62 as a mechanism and one end (inner peripheral end) are attached to the base (slit 61c of the attachment portion 61b provided on the rotating member 61), and the other end (outer peripheral end) is attached to the motor 21. A mainspring spring 63 is provided which is attached to a tension member 24 protruding from the casing 22 and wound around the outer periphery of the rotating shaft 23 of the motor 21.

  The rotating member 61 is provided with an arcuate hole 61a centered on the bearing 18 (rotating shaft 23) and, for example, an attaching portion 61b extending upward in parallel with the rotating shaft 23. The attaching portion 61b includes: A slit 61 c for attaching one end of the mainspring spring 63 is provided.

  Although not shown, the bottom plate portion 13a is provided with a screw hole (hole) into which the screw shaft portion of the fixing screw 62 that passes through the arc-shaped hole 61a of the rotating member 61 is screwed.

  The agitation of the thick food and the measurement of the thickness in the second embodiment are the same as those of the first embodiment, so the explanation of the agitation of the thick food and the measurement of the thickness is omitted, and the tension adjustment of the mainspring spring 63 is performed. Will be described.

  In FIG. 6, after loosening the fixing screw 62 and rotating the rotating member 61 clockwise, the fixing screw 62 is tightened to fix the rotating member 61, whereby the tension (biasing force) of the mainspring spring 63 is increased. It can be adjusted strongly.

  In FIG. 6, after the fixing screw 62 is loosened and the rotating member 61 is rotated counterclockwise, the fixing screw 62 is tightened to fix the rotating member 61, whereby the tension (attachment) of the mainspring spring 63 is attached. (Power) can be adjusted weakly.

  In the second embodiment, the same effects as in the first embodiment can be obtained.

  Moreover, since the elastic body is the mainspring spring 63, the rotational tension load of the rotating shaft 23 can be reduced, so that the degree of thinness (viscosity and hardness) can be measured.

  In addition, since the elastic body is the mainspring spring 63, the apparatus can be made compact (miniaturized).

  FIG. 7 is an explanatory view showing an essential part of a thickness measuring apparatus according to a third embodiment of the present invention. FIG. 7 corresponds to FIGS. 2 and 4, and FIG. 8 shows first and second mainspring springs (first and second springs). FIG. 9 is an explanatory view showing a portion of two spiral springs: an elastic body, corresponding to an enlarged side view seen from the direction of arrow D in FIG. 7, and FIG. 9 shows first and second mainspring springs (first and second spiral springs: It is explanatory drawing which shows the tension | tensile_strength adjustment mechanism of an elastic body, and is a figure corresponded in the EE sectional view taken on the line of FIG. 8, and was shown in the part same as the part shown in FIGS. Parts corresponding to the parts are denoted by the same reference numerals and description thereof is omitted.

  The thickness measuring device of the third embodiment is different from the thickness measuring device of the second embodiment in that a single mainspring spring (spiral spring: elastic body) 63 has conductivity (constituted by a conductor). The two spring springs (spring springs: elastic bodies) 64A and 64B, and the electric power is supplied to the motor 23 via the two spring springs 64A and 64B.

  That is, one end (inner peripheral end) is insulated (not shown) and attached to the base (the slit 61c of the attachment portion 61b provided on the rotating member 61), and the other end (outer peripheral end) is the casing of the motor 21. A first mainspring spring (first spiral spring) 64 </ b> A that is insulated (not shown) attached to the tension member 24 that protrudes from 22 and wound around the outer periphery of the rotating shaft 22 of the motor 21, and one end (inner peripheral end) ) Is attached to the base (the slit 61c of the mounting portion 61b provided on the rotating member 61) is insulated (not shown), and the other end (outer peripheral end) projects from the housing 22 of the motor 21. A second mainspring spring (second spiral spring) 64B which is insulated (not shown) 24 and wound around the outer periphery of the rotating shaft 22 of the motor 21 and arranged below the first mainspring spring 64A; The elastic body is composed of It has been.

  Although not shown in the figure, one end (inner peripheral end) of the first mainspring spring 64A and one end (inner peripheral end) of the second mainspring spring 64B are connected to a power source by wiring, and other than the first mainspring spring 64A. The end (outer peripheral end) and the other end (outer peripheral end) of the second mainspring spring 64B are connected to the motor 21 by wiring.

  The stirring of the thick food, the measurement of the thickness, and the adjustment of the tension in this third embodiment are the same as those of the first or second embodiment, so the stirring of the thick food, the measurement of the thickness, and the tension A description of the adjustment is omitted.

  In the third embodiment, the same effect as that of the first or second embodiment can be obtained.

  Moreover, since it was set as the structure which supplies electric power to the motor 21 via the 1st, 2nd mainspring springs 64A and 64B, it can eliminate the rotational tensile load which the wiring which supplies electric power to the motor 21 exerts on the motor 21, Thoroughness can be measured accurately.

  In the above-described embodiment, an example in which the motor 21 is rotatable with respect to the container 11 and the base by supporting the rotating shaft 23 rotatably with respect to the base (bottom plate portion 13a) has been described. By supporting the body 22 rotatably with respect to the base with a bearing (a cylindrical mounting base attached to the casing 22 in a direction in which the rotating shaft 23 protrudes from the casing 22 is supported with respect to the base with the bearing. The motor 21 may be rotatable with respect to the container 11 and the base by supporting it rotatably.

  That is, a container that stores thick food, a base that is disposed above the container, and a housing that is rotatably supported with respect to the base, thereby rotating with respect to the container and the base. A free motor, a rod-shaped body that is provided on the rotating shaft of the motor, and is provided between the thickened food, a housing of the motor and the base, and the rotating shaft of the motor rotates. An elastic body that is deformed by a reaction force of the rod-shaped body that is received from the thick food when the rod-shaped body that has entered the thick food is rotating, and a degree of thickening of the thick food. It is good also as a structure which has a display part displayed as.

  By adopting such a configuration, it is possible to obtain the same effect as the embodiment shown in FIGS.

  Further, since the motor is rotatably supported by the base, the degree of thickness can be accurately measured by firmly supporting the motor.

  Moreover, although the example which made the rod-shaped body 31 circular cross-sectional shape was shown, the cross-sectional shape of the rod-shaped body 31 may be any shape.

  Moreover, in order to make it easy to receive the reaction force of the thickening food F when the rod-shaped body 31 rotates, the example which provided the blade | wing 33 (resistor) in the rod-shaped body 31 was shown, However, only the rod-shaped body 31 shows, Since the reaction force of the thick food F is received during rotation, the thickness of the thick food F can be measured without providing the blades 33.

  Moreover, although the example which used the blade | wing 33 as a resistor was shown, the resistor was made into the wire of the screw attached to the surrounding surface of the rod-shaped body 31, a pitched paddle, a propeller, and a whisk, or the blade attached to the lower end of the rod-shaped body 31 , Screw, pitched paddle, anchor blade (U-shape in side view), propeller, rotor with a larger radius than the rod-shaped body 31 (thick), and wire of a whisk.

  Even if the resistor is composed of the above-described screw, pitched paddle, and propeller, the operation is the same as when the resistor is the blade 33, and the same effect can be obtained.

  Moreover, although the example which winds the mainspring spring 63 and the 1st, 2nd mainspring springs 64A and 64B around the outer periphery of the rotating shaft 23 of the motor 21 was shown, attachment of the mainspring spring 63, the 1st, 2nd mainspring springs 64A and 64B Depending on the position, the mainspring spring 63 and the first and second mainspring springs 64 </ b> A and 64 </ b> B may be wound around the outer periphery of the rod-shaped body 31.

  Moreover, although the example which measures the thickening degree of the thick food F was shown, the thickness measuring apparatus of this invention can also measure things like a viscosity.

  Moreover, although the example which comprised the display part 51 with the pointer | guide 25 and the scales 45A and 45B was shown, you may make it display the degree of thickness by LED etc. FIG.

  Moreover, although the example which used electric power for the battery was shown, it is good also considering a commercial power supply as electric power.
