1. Structure of Content Transfer Device 100 The structure of the content transfer device 100 of the present invention is shown in FIG. FIG. 1 is a side view showing a state of the content transfer device 100 before operation. In the following embodiment, an example will be described in which 10 mL (set amount) is transferred from a state in which 140 mL of urine LQ is contained in a urine collection cup HC having a volume of 200 mL to a test tube BT that is another container.

  First, a series of operations performed by the urine collection cup tilting device TD and the test tube cradle BS provided in the content transfer device 100 shown in FIG. 1 will be briefly described with reference to FIGS.

  The urine collection cup tilting device TD starts operation from the state shown in FIG. 1, and moves the lift plate LP in the forward direction DR1 and the upward direction DR2 in order to hold the urine collection cup HC (FIG. 8). Further, as shown in FIG. 10, the urine collection cup HC is inclined to a predetermined angle (initial inclination angle α) before the liquid level of the urine LQ reaches the edge of the urine collection cup HC. On the other hand, the test tube cradle BS rotates the test tube BT in the direction DR3 so that the urine LQ can be easily transferred (FIG. 8).

  From the state shown in FIG. 10, the urine collection cup tilting device TD further tilts the urine collection cup HC. As a result, urine is transferred from the urine collection cup HC to the test tube BT. At this time, the speed (rotational speed) for tilting the urine collection cup HC is controlled so as to be transferred at a preset flow rate Q per unit time (described later).

  Below, the structure of each part of the content transfer apparatus 100 shown in FIG. 1 is demonstrated concretely.

  In the urine collection cup HC shown in FIG. 1, urine LQ collected in advance by a patient or the like is placed. The urine collection cup HC is arranged automatically by a machine or by a human being placed on the coaster CO. The coaster cradle CS on which the coaster CO is placed is provided with a weight sensor 3 for calculating the volume of the urine LQ. The coaster cradle CS is fixed to the placement surface FD.

  The urine collection cup tilting device TD in FIG. 1 includes a lift plate LP for lifting the urine collection cup HC via the coaster CO, a motor 4a for moving the lift plate LP in the front-rear direction with respect to the urine collection cup HC, and the lift plate LP. A motor 4b that moves in the vertical direction, a fixed plate FP that integrally fixes the motor 4a and the motor 4b, a swing plate SP that rotates about the rotation axis AX1, and a motor 4d that rotates the swing plate SP And a rail plate RP integrally fixed to the swing plate SP.

  The lift plate LP shown in FIG. 1 is formed into a shape (for example, a U-shape) that allows the edge of the coaster CO to be lifted from below when moved in the upward direction DR2 after moving in the forward direction DR1. The

  FIG. 2 is a view of the content transfer device 100 shown in FIG. As shown in FIG. 2, the motor 4d is attached to the housing HS on one side, and the drive shaft of the motor 4d is engaged with the swing plate SP. For this reason, when the drive shaft of the motor 4d rotates, the swing plate SP meshing with the motor 4d rotates in the DR4 direction shown in FIG. 1 (in the reverse direction, the DR5 direction).

  The test tube cradle BS of FIG. 1 is a device for bringing the test tube BT, which is another container, close to the opening of the urine collection cup HC. For this reason, as shown in FIG. 1, the test tube cradle BS includes a swing portion SW for holding the test tube BT, a fixed portion FX connected to the swing portion SW via the rotation axis AX2, and a swing portion. And a motor 4c for turning the SW to a predetermined angle (FIG. 1).

  The motor 4c (FIG. 1) of the test tube cradle BS is attached to a fixed portion FX fixed to the mounting surface FD, and has a screw mechanism that meshes with the drive shaft of the motor 4c as it rotates. The rotation axis AX2 rotates, and the swing part SW is turned in the direction DR3 shown in FIG. 1 around the rotation axis AX2. 3 is a β arrow view of the content transfer apparatus 100 shown in FIG. As shown in FIG. 3, the test tube BT turns in the direction DR3 toward the center O of the urine collection cup HC.

  As shown in FIG. 1, a test tube BT is inserted into the swing part SW of the test tube cradle BS. Further, on the side wall of the swing part SW, three liquid level sensors (the trigger sensor 2a, the first sensor 2b, and the second sensor 2c shown in FIG. 1) for detecting the liquid level position of the test tube BT are placed at predetermined positions. It is attached. For example, the trigger sensor 2a detects a liquid level of about 0.2 mL, the first sensor 2b detects a liquid level of 3 mL, and the second sensor 2c detects a liquid level of 8 mL.

  1 is a liquid level sensor for detecting that urine has started to be transferred to the test tube BT. For this reason, it is not necessary to strictly detect that the amount is a predetermined amount. On the other hand, each of the first sensor 2b and the second sensor 2c in FIG. 1 needs to detect a predetermined level of liquid level in order to calculate an accurate time for completing the transfer. For this reason, the 1st sensor 2b and the 2nd sensor 2c are correctly attached toward the liquid level position corresponding to each predetermined amount.

  As shown in FIG. 1, the first sensor 2b and the second sensor 2c measure the liquid level at the center position C of the test tube BT. For this reason, even if the test tube BT is inclined, no problem occurs in the measurement of the liquid level. This is because the shape of the test tube BT is a cylinder in the vicinity where the first sensor 2b and the second sensor 2c are attached, so that the horizontal surface when the test tube BT is in the vertical direction, the horizontal surface in an inclined state, This is because the volume of the space formed by the side surface of the tube BT is equal on both sides of the central position C.

  The hardware configuration of a transfer control computer (transfer control device) 200 that controls the operation of the content transfer device 100 shown in FIG. 1 will be described with reference to FIG.

  As shown in FIG. 4, the transfer control computer 200 includes a CPU 20, a RAM 22, a display unit 24, a flash memory 26, an input unit 28, an I / O 30 and the like. The transfer control computer 200 includes a liquid level sensor 2 (sensors 2a to 2c in FIG. 1), a weight sensor 3 (FIG. 1), and a drive unit 4 (motors 4a to 4d in FIG. 1) via an I / O 30. It is connected.

  As shown in FIG. 4, a transfer control program 32 and an inclination speed control table 34 are stored in the flash memory 26 of the transfer control computer 200. FIG. 5 shows a data example of the tilt speed control table 34. In the slope speed control table 34 shown in FIG. 5, the flow rate Q per unit time is set to 4.6375 [mL / sec], and each value is calculated.

  The tilt speed control table 34 stores at least the rotational speed n associated with the angle θ at which the urine collection cup HC is tilted. In addition, the tilt speed control table 34 shown in FIG. 5 further stores the remaining volume R of the urine collection cup HC associated with the tilt angle θ, and is used to determine the initial tilt angle α.

  The transfer control program 32 (FIG. 4) refers to the inclination speed control table 34 shown in FIG. 5 so that the urine LQ of the flow rate Q per unit time set in advance is transferred to the test tube BT. The rotational speed n of (FIG. 1) is controlled. Specifically, the rotational speed n of the motor 4c (FIG. 1) is based on the relationship between the number of pulses required to rotate the shaft by a predetermined angle and the time required to rotate the shaft by a predetermined angle. Be controlled. A method for calculating the rotational speed n shown in FIG. 5 will be described later.

  The remaining volume R shown in FIG. 5 is a value indicating the maximum volume when the urine collection cup HC is tilted by a predetermined angle θ, that is, how much (volume) remains in the urine collection cup HC. For example, the value of the volume R can be obtained by calculating the volume partitioned by the shape of the urine collection cup HC and the liquid level position at each inclination angle θ using three-dimensional CAD or the like.

  In addition, referring to the inclination speed control table 34 shown in FIG. 5, the inclination angle necessary to transfer the set amount of 10 mL (that is, the difference between the angle at which the transfer is started and the angle at which the transfer is finished) is When the first urine collection cup HC contains 144 mL, it is about 4 ° (30 ° to 34 °), whereas when first 103 mL is contained, it is about 3 ° (45 ° to 48 °). It can be seen that it varies depending on the amount of urine LQ initially contained in the urine collection cup HC.

2. Operation of Content Transfer Device 100 The operation and control processing of the content transfer device 100 (FIG. 1) will be described with reference to the flowchart of FIG.

  First, under the control of the transfer control program 32 (FIG. 4), the motor 4a of FIG. 1 is driven to move the lift plate LP in the direction DR1 of the urine collection cup as shown in FIG. 7 (step of FIG. 6). S02).

  Further, the motor 4b is driven to move the lift plate LP in the upward direction DR2 (step S04 in FIG. 6). Thereby, as shown in FIG. 8, the urine collection cup HC is lifted together with the coaster CO. At this time, the opening of the urine collection cup HC is pushed into and held by the mold ML for pouring spout shown in FIG. 9A, and the pouring spout PS is provided.

  9A is a γ cross-sectional arrow view of the content transfer device 100 shown in FIG. 8, and in FIG. 9A, the rail plate RP to which the protrusion PJ is attached is indicated by a dotted line. As shown in FIG. 9A, the mold ML for pouring spout includes a plurality of protrusions PJ arranged in a C shape except for the position corresponding to the spout PS. Further, as shown in FIG. 9B, each protrusion PJ is formed in a taper shape that opens downward, and when the urine collection cup HC is lifted by the lift plate LP, each protrusion PJ corresponds to the urine collection cup HC. A spout PS is provided by pressing the opening from the outside.

  Further, simultaneously with step S04 in FIG. 6 (or before and after step S04), the motor 4c is driven to turn the swing part SW to a predetermined angle. Thereby, as shown in FIG. 8, the mouth of the test tube BT is brought close to the rotation axis AX1 (that is, near the spout PS of the urine collection cup HC).

  Further, the CPU 20 (FIG. 4) acquires the weight of the urine collection cup HC from the weight sensor 3, and calculates the volume of the urine LQ based on the weight (step S06 in FIG. 6). For example, the weight of the urine collection cup HC and the coaster CO may be subtracted from the weight value acquired from the weight sensor 3 and calculated from the specific gravity.

  Further, under the control of the transfer control program 32, the motor 4d is driven to rotate the swing plate SP and tilt the urine collection cup HC to a predetermined initial tilt angle α (step S08 in FIG. 6). The rotational speed until reaching the initial inclination angle α is not particularly limited, but it is preferable to perform the rotation speed as quickly as possible without causing liquid dripping.

  The predetermined initial inclination angle α is obtained by referring to the inclination speed control table 34 shown in FIG. 5 based on the volume of the urine LQ calculated in step S08. Specifically, the maximum angle θ at which the volume calculated in step S08 does not become the remaining volume R or less is determined as the initial inclination angle α. For example, if the volume of the urine LQ obtained in step S06 of FIG. 6 is 140 mL, the initial angle of 31 °, which is the maximum angle at which the volume R does not become 140 mL or less, is determined from the inclination speed control table 34 of FIG. The inclination angle α is assumed.

  By the above processing, the state shown in FIG. 10, that is, the liquid level of the urine LQ reaches the vicinity of the spout PS of the urine collection cup HC, and the contents can be transferred. Thereafter, the transfer control process (step S10 in FIG. 6) is performed as follows.

3. Details of Transfer Control Process (Step S10) Details of the transfer control process (step S10 in FIG. 6) by the transfer control program 32 will be described below with reference to the flowchart of FIG. 11, the graph of FIG. FIG. 12 is a graph showing the relationship between the elapsed time t from the start of transfer and the volume (total dispensing amount) V of the content that has already been transferred.

  In step S08 of FIG. 6, after the urine collection cup HC is tilted to a predetermined initial tilt angle α, the CPU 20 (FIG. 4) refers to the tilt speed control table 34 and starts the transfer start speed from the initial tilt angle α. n0 is determined (step S12 in FIG. 11). Specifically, the transfer start speed n0 is a value obtained by multiplying the rotation speed n corresponding to the initial inclination angle α by a predetermined value (for example, about 2.5 times) in order to prevent the occurrence of liquid dripping at the start of transfer. And For example, referring to the inclination speed control table 34 in FIG. 5, when α = 31 °, the rotational speed is 151.4 [pps], and therefore, the speed 378.5 [pps] that is 2.5 times that is the transfer start speed n0. It is determined.

  The CPU 20 (FIG. 4) tilts the urine collection cup HC around the rotation axis AX1 at the transfer start speed n0 determined in step S12 (step S14 in FIG. 11), and the liquid level is detected by the trigger sensor 2a. Is detected (step S16 in FIG. 11). As shown in the graph of FIG. 12, until the time t0 when the liquid level of the volume V0 is detected by the trigger sensor 2a, the total dispensing amount V increases linearly with a slope corresponding to the transfer start speed n0. The change in the flow rate Q per unit time is represented by a slope in the graph of FIG.

  When the liquid level is detected by the trigger sensor 2a (Yes in step S16 in FIG. 11), the CPU 20 (FIG. 4) refers to the inclination speed control table 34 and the flow rate Q per unit time of the urine LQ to be transferred. The rotational speed n of the motor 4d is controlled so that becomes a set value (step S18 in FIG. 11). That is, after the liquid level is detected by the trigger sensor 2a, the rotational speed of the motor 4d is controlled to be the same as the rotational speed n of the tilt angle control table 34 shown in FIG.

  That is, from time t0 to t1, as shown in the graph of FIG. 12, control is performed so as to approach a slope corresponding to the set flow rate per unit time. At this time, the slope of the graph from time t0 to t1 is smaller than the slope to time t0 (because the flow rate Q per unit time has decreased by 1 / 2.5). From the graph of FIG. 12, it takes a while for the flow rate Q per unit time to become constant after the time t0, but this is because the influence of the inertial force remains for a while.

  Thereafter, the CPU 20 (FIG. 4) stores the time t1 when the liquid level is detected by the first sensor 2b (step S20 in FIG. 11), and further stores the time t2 when the liquid level is detected by the second sensor 2c. (Step S22 in FIG. 11). That is, the time t1 when the volume is V1 and the time t2 when the volume is V2 shown in the graph of FIG. 12 are stored.

  Further, the CPU 20 (FIG. 4) calculates a time t3 until the set amount V3 is transferred based on the data stored in the RAM 22 in steps S20 and S22 as follows (step S24 in FIG. 11). .

  In the graph of FIG. 12, the volume increases from V1 to V2 between times t1 and t2. For this reason, the volume increase rate ΔV per unit time is (V2−V1) / (t2−t1) (corresponding to a slope a of y = ax + b). Further, when x = t1 and y = V1 is substituted into y = ax + b as a condition, b = V1-t1 (V2-V1) / (t2-t1). Then, for example, when (t1, V1) = (0.5, 2.8) and (t2, V2) = (1.8, 8), a = 4 and b = 0.8.

  As a result, the equation y = 4x + 0.8 for calculating the time t3 is obtained. Therefore, the time t3 when dispensing the set amount V3 (10 mL) from the urine collection cup HC into the test tube BT is t3 = 2.3 [s]. That is, the urine collection cup HC may be reversed after 2.3 seconds from the start of transfer. This corresponds to 1.8 seconds after time t1 and 0.5 seconds after time t2.

  Finally, when the calculated time t3 is reached, the CPU 20 (FIG. 4) controls the motor 4d so as to quickly reverse the urine collection cup in the DR5 direction in FIG. 1 (step S26 in FIG. 11). The urine collection cup HC should be rotated as quickly as possible. For example, the urine collection cup HC may be reversed in the reverse direction at the transfer start speed n0 determined in step S12 in FIG.

  With the above processing, a predetermined amount of urine LQ can be accurately transferred based on a preset flow rate Q per unit time.

4). Regarding Data of Inclination Speed Control Table 34 A method of calculating each data of the inclination speed control table 34 shown in FIG. 5 will be described below with reference to FIG. FIG. 13 is a table in which data items of the number of pulses N, the flow rate Q per unit time, the volume difference ΔR, and the required time Δt are added to the gradient speed control table 34 shown in FIG.

  When the flow rate Q per unit time (for example, 4.6375 [mL / sec]) is set for each angle θ, the rotational speed n corresponding to each angle θ can be calculated as follows.

  First, the difference of the remaining volume R in the urine collection cup HC shown in FIG. 13, the volume difference ΔR, and the flow rate Q per unit time are substituted into (expression) Δt = ΔR / Q (set value), and each angle θ The required time Δt for is obtained. Further, the rotation speed n is obtained by n = 80 / Δt. Here, 80 is the number of pulses required to tilt the urine collection cup HC by 1 degree.

  As long as at least the table in which the tilt angle θ is associated with the rotation speed n is stored as in the tilt angle control table 34 of FIG. 5, the above calculation need not be performed each time.

  FIG. 14 is a graph showing the relationship between the inclination angle θ of the urine collection cup HC and the rotational speed n at the angle θ when the flow rate Q per unit time is kept constant. In the graph shown in FIG. 14, there is a peak angle θp (indicated by a point P in FIG. 14) at which the rotation speed n is minimized. This corresponds to the fact that there is a peak angle θp at which the rotational speed n is minimum when θ = 52 ° in the data of FIG.

  That is, since the volume difference ΔR (FIG. 13) gradually increases from the start of the inclination of the urine collection cup HC until the bottom of the urine collection cup HC is reached (state of FIG. 15A), as shown in FIG. In addition, the rotational speed n decreases (in order to keep the flow rate Q per unit time constant). Further, when the bottom of the urine collection cup HC is reached for the first time (state of FIG. 15B), the volume difference ΔR becomes maximum and the rotation speed n becomes minimum at the peak angle θp (θ = 52 ° shown in FIG. 13). Thereafter, when the urine collection cup HC is further tilted, the volume difference ΔR (FIG. 13) gradually decreases, so that the rotational speed n increases as shown in FIG. 14 (to keep the flow rate Q per unit time constant). ).

  Further, the rate of decrease of the rotational speed n in the graph of FIG. 14 increases as the liquid level approaches the bottom of the urine collection cup HC (state of FIG. 15B). This is because the rate of increase of the volume difference ΔR (FIG. 13) increases as the liquid level of the urine collection cup HC approaches the bottom surface. Furthermore, when the peak angle θp (θ = 52 ° shown in FIG. 13) is exceeded, the increasing rate of the rotational speed n shown in the graph of FIG. 14 gradually increases. This is because when the liquid level of the urine collection cup HC exceeds the bottom surface (state of FIG. 15C), the decreasing rate of the volume difference ΔR (FIG. 13) gradually decreases.

5. Other Embodiments In the above-described embodiment, control is performed using the tilt angle control table 34 (FIG. 5) in which the rotation speed n is stored in association with the tilt angle θ. Similar data may be obtained and controlled from a calculation formula corresponding to the shape.

  In the above-described embodiment, the flow rate Q per predetermined unit time is set to the same setting as that of the tilt angle control table 34, and the tilt angle (rotational speed) is controlled. You may make it control so that it may become a flow volume different from the setting of the table 34. FIG. For example, the flow rate Q per unit time shown in FIG. 5 is twice the set value by using the tilt angle control table 34 generated as the set value 4.6375 [mL / sec], that is, a unit of 9.275 [mL / sec]. When it is desired to obtain a flow rate per hour, the rotational speed n corresponding to each angle θ of the tilt angle control table 34 may be doubled.

  In the above embodiment, the flow rate Q per unit time set in advance is a constant value, that is, a value obtained from a linear equation as shown in the graph of FIG. 12 (the portion of the slope a corresponding to the flow rate Q). However, the present invention is not limited to this. For example, the flow rate Q per unit time at each angle θ may be set to a value that increases or decreases at a constant rate (a value obtained from a nonlinear equation).

  In the above embodiment, the flow rate Q per unit time is set to a constant value and the rotation speed n is changed. However, the rotation speed n is set to a constant value and the flow rate Q per unit time is changed. May be. At this time, the urine collection cup HC may be reversed when the total flow rate after adding the transfer (a sum of flow rates that change with time) reaches the set amount.

  In the above embodiment, the transfer start speed n0 is set to a predetermined multiple (for example, about 2.5 times) the rotation speed n corresponding to the initial inclination angle α in order to prevent the occurrence of dripping at the start of the transfer. However, the present invention is not limited to this. For example, the transfer start speed n0 may be the same as the rotation speed n corresponding to the initial inclination angle α. At this time, since the flow rate Q per unit time is constant from the start of the transfer, even if the sensor 2 is not provided (FIG. 1), the flow rate Q per unit time is shifted from the relationship of t3 = V3 / Q. From the set amount V3 to be changed, the time t3 at which the transfer is finished can be easily calculated.

  In the above embodiment, the rotation axis AX1 (FIG. 1) for tilting the urine collection cup HC is provided near the spout of the urine collection cup HC. However, the present invention is not limited to this. An axis AX1 (FIG. 1) may be provided to reduce the fluctuation of the liquid level.

  In the above embodiment, the test tube BT is inclined (FIG. 8). However, the present invention is not limited to this, and the test tube BT may not be inclined.

  In the above embodiment, control is performed using data (inclination angle control table 34 in FIG. 5) that does not consider the viscosity and surface tension of urine LQ. However, the present invention is not limited to this, and the viscosity and surface tension of urine LQ are considered. Control may be performed using the corrected data.

  In the above embodiment, when the spout PS is provided, the opening of the urine collection cup HC is slightly deformed for the purpose of holding the container stably and preventing liquid dripping by narrowing the width of the liquid. However, the present invention is not limited to this, and the opening of the urine collection cup HC may not be deformed at all.

  In the above embodiment, the urine collection cup HC having a flat bottom is used. However, the present invention is not limited to this, and a container having a non-planar bottom (for example, a container having a curved bottom) can also be used.

  In the above embodiment, urine (liquid) is transferred as the contents, but the present invention is not limited to this, and other liquids or powdered (granular) solids may be transferred.
