The operation panel 4 is provided with an operation unit 40 such as various operation buttons for receiving an operation of an operator and a display unit 41 configured by using a light emitting element such as an LED to display a necessary situation.

<Stirring mechanism 5>
FIG. 2 is a side sectional view showing an example of a main part of the stirring mechanism 5 included in the stirring device 1 described in the present application. The main part of the stirring device 1 is a stirring mechanism 5 that is a movable part, and the stirring mechanism 5 includes a plurality of holding portions 50 that respectively store the storage containers 2 that can store the storage target. It is held detachably by the holding portion 50. The accommodating container 2 is a container formed by molding a resin such as high density polyethylene (HDPE: High Density Polyethylene), and has a bottomed cylindrical shape with an upper opening, and the opening is closed by a lid 20. .. The holding unit 50 holds the storage container 2 via a temperature measurement unit 501 that measures the temperature of the storage container 2 to be held, and also stably holds the storage container 2 and the temperature measurement unit 501. For this purpose, a spacer (height adjusting member) 502 and a restraining member 503 are provided. Details of the container 2 and the holding unit 50 including the temperature measuring unit 501, the spacer 502, and the restraining member 503 will be described later.

The plurality of holding portions 50 that respectively hold the storage containers 2 are fitted into fixed shafts 51 arranged in the center of the stirring mechanism 5 via bearings, and are respectively attached to the distal end portions of arm bodies 52 that extend radially in a substantially horizontal direction. It is arranged. Since the tip end of the arm body 52 is slightly bent back toward the fixed shaft 51 side, the arm body 52 is generally Y-shaped in cross section as a whole. Therefore, each storage container 2 is arranged so that the opening is inclined from above toward the fixed shaft 51 side by being held by the holding portion 50.

Each holding portion 50 is fixed to a columnar support shaft 53 that is rotatably supported at the substantially tip end of an arm body 52, and rotates about the rotation of the support shaft 53. The central axis that is the rotation axis of the support shaft 53 and the central axis of the container 2 housed in the holding unit 50 are located on a substantially straight line. Therefore, the storage container 2 and the holding portion 50 that holds the storage container 2 rotate about the spindle 53 and the center axis of the storage container 2 as the rotation axis A1. The center axis of the container 2 and the rotation axis A1 do not necessarily have to coincide with each other.

The arm body 52 is rotatably supported by a fixed shaft 51, and a revolving gear 54 is fixed to the lower end of the fixed shaft 51 so that the teeth orbit. In the arm body 52, a pair of driving pulleys 55a are fitted over the orbiting gears 54 via bearings, and a driving force for rotating the holding portion 50 is provided on the lower end side of the driving pulleys 55a. The relay gear 56 that relays is integrally fixed.

The revolution gear 54 meshes with a drive gear 57 connected to a drive motor (not shown). A rotation gear 58 that meshes with the relay gear 56 is connected to the drive gear 57 at a position opposite to the fixed shaft 51.

A powder brake 59 for control is connected to the rotation gear 58. When the voltage applied to the powder brake 59 is increased, the rotation speed of the rotation gear 58 is gradually reduced, whereby the rotation gear 54 is rotated relative to the rotation speed of the arm body 52 fixed to the revolution gear 54. The rotation speed of 58 decreases. Further, when the voltage applied to the powder brake 59 is lowered, the rotation speed of the rotation gear 58 is increased stepwise, whereby the rotation gear 54 is rotated with respect to the rotation speed of the arm body 52 fixed to the revolution gear 54. The rotation speed of 58 increases.

A rotation pulley 55b is externally fitted to the support shaft 53 fixed to the holding portion 50, and a belt body 55c is installed between the rotation pulley 55b and the drive pulley 55a.

The outline of the operation of the stirring mechanism 5 configured as described above will be described. The driving gear 57 rotates by driving the driving motor. As the drive gear 57 rotates, the arm body 52 rotates. That is, the holding unit 50 revolves around the revolution axis A2 with the center axis of the fixed shaft 51 as the revolution axis A2.

Further, as the arm body 52 rotates, the meshed relay gear 56 rotates according to the arm body 52 while rotating the rotation gear 58. As the rotation gear 58 rotates, the drive pulley 55a provided integrally with the rotation gear 58 also rotates according to the arm body 52. In such a state, by adjusting the voltage applied to the powder brake 59, the rotation around the rotation axis A1 of the holding unit 50 can be controlled.

The rotation control will be described. When the voltage applied to the powder brake 59 is 0, the rotation gear 58 rotates freely without being braked, so that the belt body 55c installed between the drive pulley 55a and the rotation pulley 55b is rotationally driven. It becomes a state not to do. In such a state, the holding unit 50 only revolves around the revolution axis A2.

By increasing the voltage applied to the powder brake 59, the rotation gear 58 is braked and the rotation speed is reduced, and the relay gear 56 meshed with the rotation gear 58 in comparison with the rotation speed of the arm body 52. The rotation speed decreases. Further, the rotation speed of the drive pulley 55a provided integrally with the relay gear 56 decreases. Then, the number of rotations lower than the number of rotations of the arm body 52 is transmitted to the rotation pulley 55b via the belt body 55c, so that the holding section 50 rotates about the rotation axis A1.

As described above, various members such as the rotation gear 58, the powder brake 59, the drive pulley 55a, the rotation pulley 55b, and the belt body 55c rotate the holding portion 50 about the support shaft 53 (rotation shaft A1). Functions as a rotation part. Further, various members such as the revolution gear 54 and the arm body 52 function as a revolution unit that revolves the holding unit 50 around a fixed shaft 51 (revolution shaft A2) different from the rotation shaft A1. That is, the stirring device 1 revolves around the storage container 2 that can store the storage target, the holding unit 50 that holds the storage container 2, the rotation unit that rotates the holding unit 50 about the rotation axis A1, and the holding unit 50. An orbiting section for revolving around the axis A2. By holding the storage container 2 by the holding portion 50 and rotating and revolving the same, that is, performing planetary rotation, it becomes possible to improve the stirring efficiency of the storage target stored in the storage container 2.

<Holder 50 and container 2>
FIG. 3 is a schematic diagram illustrating an example of the holding unit 50 and the storage container 2 included in the stirring device 1 described in the present application. FIG. 3A is an external front view, and FIG. 3B is a side sectional view in the B-C direction in FIG. 3A. Further, FIG. 4 is a schematic front view showing an example of the appearance of a part of the holding unit 50 and the storage container 2 included in the stirring device 1 described in the present application. FIG. 4 is a schematic front view showing the temperature measurement unit 501, the spacer 502 and the restraining member 503, and the storage container 2 with the holding body portion 500 of the holding portion 50 removed from the state shown in FIG. ..

The holding main body portion 500 of the holding portion 50 has a bottomed cylindrical shape with an upper opening, and the bottom portion is fixed to the upper end of the support shaft 53. A metal plate-shaped restraining member 503 is screwed to the inner bottom of the holding body 500. A temperature measuring unit 501 having a substantially cylindrical shape is placed on the upper surface of the restraining member 503, and the container 2 is placed on the upper surface of the temperature measuring unit 501. Further, a cylindrical spacer 502 is placed on the side wall of the holding body 500. On the side wall of the holding main body 500, protrusions are provided at three locations, and engage with three engaging recesses 502a recessed in the lower portion of the spacer 502 to hold the holding main body 500 and the spacer 502. Prevents deviation during rotation between and.

Further, the lid 20 of the storage container 2 is designed to be placed on the spacer 502. Engagement protrusions 502b are provided at three locations on the upper portion of the spacer 502 so as to engage with three recesses provided at the lower portion of the lid body 20, and the space between the spacer 502 and the lid body 20 is engaged. Prevents misalignment during rotation.

The inner diameter of the holding main body 500 and the inner diameter of the spacer 502 are substantially equal to each other, and are formed slightly larger than the outer diameters of the temperature measuring unit 501 and the accommodating container 2. It is placed so that it is inserted into. Therefore, the holding body portion 500, the spacer 502, and the temperature measuring unit 501, which have a circular outer diameter in a plan view, are arranged so that their centers substantially coincide with the rotation axis A1. The storage container 2 is held so that the center of the bottom surface substantially coincides with the rotation axis A1.

The cylindrical outer shape of the temperature measurement unit 501 is due to a housing 501a that houses various members described later. A cylindrical support member 501b having a cross-sectional diameter of 10 mm and a height of about 5 mm, which is made of an elastic body such as synthetic resin foam, rubber, or soft resin, is placed on the upper surface of the housing 501a. There is. Examples of the synthetic resin foam include polyurethane foam and polypropylene foam. Examples of rubber include natural rubber and silicone rubber. The size of the support member 501b is not particularly limited, but it is preferable that the cross-sectional diameter is 5 to 40 mm and the height is about 1 to 20 mm. The shape of the support member 501b is not particularly limited, but a cylindrical shape such as a cylinder or a square tube is preferable. A detection member 501c having a detection unit 501c1 (see FIG. 5A, etc.) such as a thermistor for detecting temperature is arranged on the upper surface of the support member 501b, and the detection member 501c is supported by the support member 501b. The bottom portion of the storage container 2 placed on the upper surface of the temperature measurement unit 501 is formed in a concave shape that is gently recessed inward from the edge portion to the center portion. When the storage container 2 is placed on the upper surface of the temperature measurement unit 501, the supporting member 501b is located near the center of the bottom of the storage container 2 formed in a concave shape, and the detection unit 501c1 is located outside the bottom of the storage container 2. The detection member 501c is supported while being pressed from below so as to abut. By supporting the detection member 501c with the support member 501b formed of an elastic body, the detection unit 501c1 can be brought into contact with the outer side of the bottom of the container 2 regardless of the shape of the bottom. You can Further, the support member 501b formed by using the elastic body is deformed by being crushed by the bottom surface of the storage container 2 by the centrifugal force of the revolution. At this time, the bottom edge of the storage container 2 contacts the upper surface of the housing lid 501a2, so that the storage container 2 under agitation is stably supported.

3 and 4, the holding unit 50 holds the container 2 and the temperature measuring unit 501 having the housing 501a. However, when it is not necessary to measure the temperature, the temperature measurement is performed. It is also possible to use the unit 501 by removing the unit 501 and holding the storage container 2. Further, when the temperature measuring unit 501 is removed, a restraining member 503 for restraining sliding of the temperature measuring unit 501 and a spacer 502 for fixing the lid 20 of the container 2 raised by the height of the temperature measuring unit 501. And become unnecessary. That is, in the stirring device 1 described in the present application, the temperature measuring unit 501 and the restraining member 503 and the spacer 502 are attached and used when the temperature is measured, and the temperature measuring unit 501 and the restraining member are used when the temperature is not measured. 503 and the spacer 502 can be removed and used. When the members such as the temperature measurement unit 501 and the spacer 502 are not used, the lid 20 of the container 2 is placed on the side wall of the holding body 500, and the lid 20 is provided on the side wall of the holding body 500 in a protruding manner. The formed protrusion engages with a recess formed in the lower portion of the lid body 20.

The temperature measuring unit 501 will be described in more detail. 5A is a schematic plan view showing an example of the temperature measuring unit 501 included in the stirring device 1 described in the present application, and FIG. 5B is a schematic side sectional view showing an example of the temperature measuring unit 501 included in the stirring device 1 described in the present application. Is. The housing 501a of the temperature measurement unit 501 includes a housing body 501a1 and a housing lid 501a2 that are made of hard resin. Note that FIG. 5A shows the housing lid body 501a2 in a transparent manner in order to make it easier to visually recognize the inside.

The housing main body 501a1 of the temperature measurement unit 501 is provided with an accommodation chamber having a rectangular shape in a plan view, which is partitioned by a wall surface portion a10, within an outer shape of a circular shape in a plan view. The four corners of the storage chamber are open and serve as ventilation holes, which prevents the inside of the housing main body 501a1 from becoming hot. Various members and circuits such as a part of the detection member 501c, the measurement control unit 501d, and the unit power supply unit 501e are housed in the housing chamber of the housing body 501a1.

The detection member 501c is formed by molding a flat detection section 501c1 and a conducting wire 501c2 connected to the detection section 501c1 into a flexible band shape with a protective resin layer. The detection unit 501c1 is located substantially at the tip. Various temperature sensors such as a thermistor, a thermocouple, and a resistance temperature detector can be used for the detection member 501c having the detection unit 501c1. For example, when the detection member 501c is formed using a thermistor, the number of the conductive wires 501c2 is two, and the temperature is detected based on the electric resistance value of the detection unit 501c1 measured through the two conductive wires 501c2. When a thermistor is used as the detection member 501c , it is possible to expect improvement in measurement accuracy and response speed by selecting an element having a small heat capacity. Note that it is also possible to replace only the detection member 501c, which makes it possible to select the optimum detection member 501c for the measurement target. In addition, a through hole is formed in a portion of the contact surface of the support member 501b that supports the detection member 501c corresponding to the detection unit 501c1. Therefore, one surface of the detection unit 501c1 having a flat shape contacts the outer bottom portion of the housing container 2, and the other surface contacts the air without directly touching other members. Note that the through holes may be filled with a heat insulating member to suppress heat conduction. That is, the back side direction of the contact surface of the detection unit 501c1 is configured to have a void or a heat insulating member, thereby suppressing heat conduction with other members and eliminating temperature measurement error as much as possible. can do. Further, the detection member 501c is supported at a position slightly apart from the center of the bottom so as to detect the temperature of the portion of the storage container 2 that is deviated from the center of the bottom. By measuring the temperature at a position distant from the center of the bottom, it is possible to avoid the center of rotation where the stirring efficiency is relatively low, and therefore the measurement accuracy is expected to improve. In the detection member 501c, a part of the conducting wire 501c2 extending from the detecting portion 501c1 provided on the housing lid 501a2 is accommodated in the accommodating chamber, and the end portion of the accommodating conducting wire 501c2 is measured and controlled. It is connected to the part 501d. The detection part 501c1 of the detection member 501c and the support member 501b are arranged outside the housing 501a in order to detect the temperature of the bottom of the housing container 2 from the outside. The entire detection member 501c does not necessarily have to be outside the housing 501a, and a part of the detection member 501c, for example, a part of the conducting wire 501c2 as in the present embodiment is housed in the housing chamber of the housing 501a. May be.

The measurement control unit 501d controls the entire temperature measurement unit 501, and performs each calculation and input/output of information. The unit power supply unit 501e includes a battery B and a battery socket 501e1. As the battery B, for example, a chemical battery such as a button-type battery having a positive electrode at its surface and a negative electrode at its edge is used, such as a CR2032 standard lithium battery defined by IEC (International Electrotechnical Commission) 60086. The battery socket 501e1 includes a leaf-spring-shaped positive electrode terminal that abuts on the surface of the battery B and a substantially annular negative electrode terminal that abuts on the edge of the battery B, and supplies the power from the battery B to the measurement controller 501d. Supply power. By using the battery socket 501e1 including such a positive electrode terminal and a negative electrode terminal, it is possible to prevent the position of the battery B from shifting even during planetary rotation. Note that these various members and circuits can be appropriately designed. For example, as the unit power supply unit 501e, a chemical battery is not used, but an electromotive force due to electromagnetic induction from the outside is used as a power supply. It is possible to

The metal plate-shaped restraining member 503 is configured to include an annular portion in a plan view and a substantially cross-shaped projection portion that radially extends from the outer edge of the annular ring. The restraining member 503 having such a shape has an outer shape that fits into the fitting receiving portion a12 recessed in the lower surface of the housing 501a of the temperature measuring unit 501. In addition, insertion holes 503a through which the screws are inserted are formed at three locations in the annular portion of the inhibition portion. The restraining member 503 can be screwed to the inner bottom surface of the holding body 500 by a screw inserted into the insertion hole 503a. By screwing the restraining member 503 onto the inner bottom surface of the holding body portion 500, a convex portion having a plan view shape of the restraining member 503 is formed on the inner bottom surface of the holding body portion 500.
