Abstract

PROBLEM TO BE SOLVED: To provide a quantitative discharge device using a valve member which is designed so that solid matter cannot find its way into a gap between the inner wall surface of a circumferential drum part connected with the inner end part of an outer valve opening of a short cylinder-like part and the outer wall surface of the edge part of an inner valve opening which is rotatably displaced.SOLUTION: This quantitative discharge device using a valve member includes the following structural features. An inclined guide piece with a broad width, the lower end edge part of which crosses over the rotating direction of an inner cylinder in straight line or somewhat curved fashion, is integrally installed or a guide part with an inclined surface is integrally formed, on the inner wall surface of a short cylindrical part with an outer valve opening of an outer cylinder. In addition, the lower end edge part of the inclined guide piece or the guide part with an inclined surface, is positioned so as to allow the lower end edge part to slide into contact with the outer circumferential wall of the inner cylinder or approach the outer circumferential wall as far as the lower end edge part can. Besides, the solid matter which drops from a hopper through the opening of an outer valve, is free from the biting of the solid matter by the inner end part of an outer valve opening of the short cylindrical part and the rear side edge part of an inner valve opening of the inner cylinder which is rotatably displaced.

Description

  The present invention relates to a quantitative discharge device using a valve member capable of discharging a solid matter such as a powdery substance other than a liquid, a granular substance such as rice, a bean, cut meat and vegetables.

  In Patent Document 1 and Patent Document 2, the valve member includes an outer cylinder as an outer valve, an inner cylinder as an inner valve that is rotatably incorporated in the outer cylinder, and a slide on the inner cylinder. A push-out actuating body in which a moving part is incorporated and a follower actuating rod, and on the other hand, a drive source side includes a drive source and a drive actuating rod that moves horizontally by the force of the drive source and guided by a support member, Engagement / disengagement of the operating rod in which the engagement portion of the rear end portion of the valve member is engaged with and disengaged from the connecting support attached to the driving operating rod when the driven operating rod of the valve member and the driving operating rod on the driving source side are connected. A fixed-volume discharge device using a valve member having a structure is disclosed.

  Thus, since the inner peripheral surface of the inner cylinder is circular in cross section, when the inner cylinder rotates 180 degrees and the inner valve opening communicates with the discharge port of the outer cylinder, the inner cylinder is accommodated in the inner cylinder. Although all liquid soups, such as ingredients, have the advantage of flowing down naturally, the contents that fall from the hopper through the outer cylinder form rice, soybeans, processed materials, food materials, processed foods (for example, fried rice, fried rice) In the case of a solid material such as a material, a phenomenon occurs in which a bite occurs between the inner end portion of the outer valve opening of the short cylindrical portion of the outer cylinder and the rear side edge portion of the inner valve opening that is rotationally displaced. As a result, it penetrates so that solid matter is drawn into the gap between the inner wall surface of the peripheral body portion connected to the inner end portion of the outer valve opening of the short cylindrical portion and the outer wall surface of the edge portion of the inner valve opening that is rotationally displaced, There may be a problem that the inner cylinder does not rotate.

  To add to this point, since a seal member is generally provided on the outer peripheral wall of the inner cylindrical body, a gap is provided between the inner peripheral wall of the outer cylindrical body and the outer peripheral wall of the inner cylindrical body. Although there is no problem when liquid (for example, soups falling from the hopper) enter the gap, in the case of solid matter, the inner cylinder having the inner valve opening is located on the lower end side of the outer cylinder. Since it rotates to the discharge port, the biting of the solid matter falling by the inner end part of the outer valve opening of the upper short cylindrical part of the outer cylinder and the rear side edge part of the inner valve opening of the rotating inner cylinder "Occurs. As described above, this biting phenomenon is caused by the gap between the inner wall surface of the peripheral body portion connected to the inner end portion of the outer valve opening of the short cylindrical portion of the outer cylinder body and the outer wall surface of the edge portion of the inner valve opening that is rotationally displaced. As a result, it is allowed to allow the solid matter to enter, and this imposes a load on the rotation of the inner cylinder. Therefore, when the object falling from the hopper is not a liquid but a solid, it is expected to prevent the biting phenomenon.

  In addition, in the quantitative discharge devices described in Patent Document 1, Patent Document 2, and the like, the inner cylinder is cylindrical, whereas the inner valve opening is a circle (long) formed in a part of the wall surface of the inner cylinder. Therefore, there is a problem that a part of the solid matter remains on the edge of the inner valve opening and the like, and even if the push-out operating body moves forward, it is not completely discharged from the discharge port of the outer cylinder. Therefore, it is desirable to have a quantitative discharge device that uses a valve member that smoothly discharges (including drops) all solid matter that has fallen into the inner cylinder from the inner valve opening to the discharge port of the outer valve.

JP 2004-188385 A JP 2007-7505

  The intended purpose of the present invention is to allow solids to enter the gap between the inner wall surface of the peripheral body portion connected to the inner end portion of the outer valve opening of the short cylindrical portion and the outer wall surface of the edge portion of the inner valve opening that is rotationally displaced. This is to prevent the rotation of the inner cylinder. The second purpose is to smoothly push out all powdery or solid matter that has fallen into the inner cylinder from the inner valve opening to the outlet of the outer valve.

  In the quantitative discharge device using the valve member of the present invention, the valve member includes an outer cylinder as an outer valve, an inner cylinder as an inner valve that is rotatably incorporated in the outer cylinder, and an inner cylinder. And a push-out actuating body having a sliding portion incorporated therein. In a metering discharge device using a valve member in which the inner cylinder is rotated by a driving force of a drive source, a short valve that forms an outer valve opening of the outer cylinder. A wide inclined guide piece whose lower end edge intersects linearly or slightly curvedly with respect to the rotation direction of the inner cylinder is integrally provided on the inner wall surface of the cylindrical portion, or a guide portion having an inclined surface is integrally formed. The lower end edge portion of the inclined guide piece or the guide portion having the inclined surface is positioned so as to be in slidable contact or as close as possible to the outer peripheral wall of the inner cylindrical body, and falls from the hopper through the outer valve opening. Of the inner cylinder in which the solid material is rotated and displaced with the inner end portion of the outer valve opening of the short cylindrical portion. Characterized in that to prevent bite at the rear edge of the opening.

  In the above configuration, the guide piece is formed in a meniscus shape whose lower end edge portion is in a horizontal state, while the upper end edge portion is fixed to a short cylindrical inner wall surface. Also, a fitted portion is provided on the distal end side of the inner peripheral wall of the inner cylinder, while a protruding fitting portion that fits the fitted portion is provided on the distal end portion of the sliding portion of the push-out operating body. The push-out actuating member is a discharge port of the outer cylindrical body together with the inner cylindrical body by the driving force of the driving source in a state in which powdery matters or solids other than the liquid dropped from the hopper are accommodated in the fitted portion. It is characterized by rotating to the right.

  Here, “located as close as possible” means, for example, when the solid is granular, the inner valve opening through which the solid rotates with the inclined guide piece or the lower edge of the guide. It means that it does not enter into the gap between the rear side edge portion.

  Here, the “solid” includes granular materials such as rice, beans, cut meat and vegetables. In addition, the solid material includes not only the material before processing but also the material after processing (for example, fried rice). In addition, the “solid matter” here may include a liquid mainly composed of a solid matter.

(A) Since the solid matter does not enter the gap between the inclined guide piece or the lower end edge of the guide portion and the rear side edge portion of the inner valve opening of the inner cylinder body that is rotationally displaced, the solid matter is a short cylindrical shape. It does not enter the gap between the inner wall surface of the peripheral body portion connected to the inner end portion of the outer valve opening of the portion and the outer wall surface of the edge portion of the inner valve opening that is rotationally displaced. Therefore, the rotation of the inner cylinder is not hindered.
(B) The invention described in claim 2 can smoothly discharge all the powdery matter and solid matter that have fallen into the inner cylindrical body from the discharge port of the outer valve.
(C) In the invention according to claim 3, the guide piece can be easily fixed to the inner surface of the short cylinder.

  First, one of the characteristic parts of the present invention will be described, and then each member constituting the present invention will be described in detail. 1 to 14 are examples of the present invention.

(1) Characteristic part 1 of the present invention
One of the features of the present invention is shown in particular in FIGS. In the present invention, since the thing thrown into the hopper 5 is a solid matter b, the solid matter b rotates and displaces with the inner end portion 61 a of the outer valve opening 3 of the short tubular portion 61 of the outer tubular body 2. 11 has a guiding function for guiding the solid material b to the inner valve opening 12 of the inner cylindrical body 11 on the inner wall surface of the short cylindrical portion 61 so as not to bite with the rear side edge portion 12b of the inner valve opening 12 of the inner cylindrical body 11. And an inclined guide piece or an inclined surface having both functions of an intrusion prevention function for preventing the solid material b from entering between the inner wall surface of the peripheral barrel portion 2a of the outer cylinder 2 and the outer wall of the inner cylinder 11. That is, the guide unit 65 is provided.

  The short cylindrical portion 61 may be cylindrical or rectangular. In addition, a fitting receiving portion 62 having a stepped section in which a lower end portion of the hopper 5 is detachably fitted is connected to the upper end of the short cylindrical portion 61 in a protruding wall shape.

  In the present invention, the valve member V includes an outer cylinder 2 as an outer valve, an inner cylinder 11 as an inner valve that is rotatably incorporated in the outer cylinder 2, and a sliding portion on the inner cylinder. And a push-out actuating body 18 in which the inner cylinder 11 is rotated by the driving force of the driving source 21.

  Thus, on the inner wall surface of the short cylindrical portion 61 forming the outer valve opening 3 of the outer cylindrical body 2, the lower end edge portion 65 b intersects with the rotation direction of the inner cylindrical body 11 in a straight line or a slightly curved shape. A wide inclined guide piece 65 is integrally provided, or a guide portion 65 having an inclined surface is integrally formed, and the lower end edge 65b of the inclined guide piece or the guide portion 65 having the inclined surface is formed by the inner cylinder. The solid matter b, which is positioned so as to be in sliding contact with or infinitely close to the outer peripheral wall 66 of the body 11 and dropped from the hopper 5 through the outer valve opening 3, is inside the outer valve opening 3 of the short cylindrical portion 61. The end portion 61a and the rear side edge portion 12b of the inner valve opening 12 of the inner cylinder 11 that is rotationally displaced are prevented from biting.

  With reference to FIG. 5, reference numeral 12 a is a front side edge of the inner valve opening 12. Therefore, in this embodiment, as shown in FIGS. 5 and 14, the inner cylinder 11 rotates counterclockwise with respect to the outer cylinder 2.

  In the present embodiment, an inclined guide piece is used as an example of the guide means 65 that also functions as a solid material b guide function and an intrusion prevention function. The inclined guide piece 65 is formed, for example, in a meniscus shape, but may have a rectangular shape depending on the design. In the case of the meniscus-shaped embodiment, the arc-shaped upper edge 65 a is fixed to the inner wall surface of the short cylinder 61, while the lower edge 65 b is in a horizontal state and rotates the inner cylinder 11. It is positioned so as to intersect (preferably orthogonal) the moving direction. The lower end edge portion 65b is formed in, for example, a cutting edge (inclined) shape.

  As shown in FIG. 5, a pair of inclined guide pieces 65 are provided symmetrically. In addition, the inclined guide piece 65 may be formed in a plate shape having a required width and welded to the inner wall surface of the short cylinder 61, or may be formed thick and formed on the inner wall surface of the short cylinder 61. You may do it. In short, it may be a member or a part that combines the function of guiding the solid material b and the function of preventing intrusion.

  The shape of the inclined guide piece 65, particularly the width in the length direction of the outer cylinder 2 or the inner cylinder 11, is the width of the left and right front and rear of the opening at the lower end of the hopper 5 and the inner valve opening 12 of the inner cylinder 11. Preferably, the lower end edge of the inclined guide piece or the guide portion having the inclined surface is positioned inside the inner valve opening 12 in the standby state of the inner cylinder 11. Is set.

(2) Feature 2 of the present invention
Next, the characteristic part 2 of the present invention will be described. The characteristic part 2 is fitted to the inner cylinder 11 so that the push-out actuating body 18 corresponding to the piston can rotate together with the inner cylinder 11, and the inner cylinder 11 is in relation to the outer cylinder 2. Then, the push-out actuating body 18 moves forward, and the powder and solid matter stored on the distal end side of the inner cylindrical body are discharged to the outside through the inner valve opening 12 and the discharge port 6 of the outer valve. On the other hand, at least when the push-out actuating body 18 rotates together with the inner cylinder 11 and is in a standby state, the solid material is received from the hopper 5 to the front end side of the inner cylinder. To retreat.

  Specifically, for example, as shown in FIGS. 13 and 14 and the like, a fitted portion 51 having a recessed section is provided on the distal end side of the inner peripheral wall of the inner cylinder 11, while the push-out actuating body 18 is slid. A protruding fitting part 52 that is just fitted to the fitted part 51 is provided at the tip of the moving part 18a, and the push-out actuating body 18 removes the powdery substance or solid matter b dropped from the hopper 5. The inner cylinder 11 and the discharge port 6 of the outer cylinder 2 are rotated by the driving force of the drive source 21 disposed in the fitted portion 51 and disposed on the rear side of the pusher 18. .

  Here, referring to FIG. 14, the fitted portion 51 gradually becomes narrower in a U-shaped cross section or from the opening portion 51 a on the outer peripheral surface to the non-opening portion 51 b corresponding to the inner bottom surface. The cross-sectional shape of the fitted portion 51 may be U-shaped, but preferably a “valley shape” as shown in the embodiment. When the cross-sectional shape of the fitted portion 51 is a valley shape, when the inner cylinder 11 is rotated 180 degrees to be in a discharge state, the opening portion 51a of the fitted portion 51 is more than the non-opening portion 51b. Is also wide, that is, the opening 53 of the fitted part 51 has a mountain shape, so that the powder and solid matter b in the opening 53 of the fitted part 51 are discharged from the outlet of the outer cylinder 2. When exiting 6 (for example, falling and being discharged from the discharge port), all of the weight is smoothly dropped or pushed out without remaining in the inner cylinder 11. The size (width) of the opening portion 51a of the fitted portion 51 is set so as to match the outer valve opening 3, the inner valve opening 12, and the like.

  Desirably, as shown in FIG. 2, when the push-out operating body 18 is retracted and retracted to the origin position, the protruding fitting portion 52 of the push-out operating body 18 is the rear end portion of the fitted portion 51. It is set so as not to deviate from. FIG. 2 shows a state where the thick fitting portion 52 of the push-out actuating body 18 is supported by the rear end portion of the fitted portion 51 of the inner cylinder 11 when the push-out actuating body 18 is retracted. .

  Further, in this embodiment, as shown in FIG. 2, the front end surface of the fitting portion 52 of the push-out operating body 18 is located on the rear side when the inner cylinder 11 receives the solid material b from the hopper 5 as a reference. Since it is slightly inclined, it is easy to accept the solid matter b and at the same time to extrude it.

(3) Specific configuration of each member X is a metering discharge device using a valve member, and the outer cylinder and inner cylinder of the metering discharge device X are arranged laterally on the upper surface of the upper horizontal plate 1a of the fixed member 1. It is arranged. The upper horizontal plate 1a is appropriately formed with a plurality of openings or notches such as a valve member opening, a drive gear opening, and a transmission gear opening without reference numerals. In addition, on the lower surface side of the upper horizontal plate 1a, one drive source (drive motor) 21 for the fixed quantity discharge device X is disposed in the lateral direction via a motor mounting plate.

  A case-like mounting frame 1c is provided at the rear end portion on the upper surface side of the upper horizontal plate 1a, and a through-hole of the mounting frame 1c is provided with an operating rod (hereinafter referred to as a “following operating rod 19”). The rear end portion of the drive actuating rod 20 that locks “)” is guided. The follower operating rod 19 and the drive drive operating rod 20 can be detachably connected by an engaging rod engaging / disengaging structure Z described later.

  The mounting frame 1c is provided with a plurality of position detecting means S2 for the push-out actuating body 18 with a required interval. An anti-rotation stand 37 for the push-out actuating body 18 is installed in the mounting frame 1c, and the upper surface of the anti-rotation stand 37 is engaged with an engaging portion 20b provided on the drive operating rod 20. A joint portion 37a is formed. The engagement portion 20b of the drive actuation rod 20 is a vertical engagement piece (for example, an engagement pin) that intersects the drive actuation rod 20, while the engaged portion 37a is a long groove-like guide groove. . In the present embodiment, an index or magnet piece 38 for the detecting means S2 is provided in a horizontal state at the upper projecting end of the engaging portion 20b. Therefore, the push-out actuating body 18 can reciprocate via the rotation preventing means constituted by the engaging portion 20b provided on the drive operating rod 20 and the engaged portion 37a provided on the fixed-side member 1.

  Further, the fixed side member 1 has a lower horizontal plate 1b facing the upper horizontal plate 1a, and a driving means (solenoid) 31 constituting the clutch mechanism Y is arranged in the lateral direction on the upper surface of the lower horizontal plate 1b. It is installed.

(4) Outer cylinder 2
The outer cylindrical body (outer valve) 2 includes a long cylindrical peripheral body portion 2a that is open at both left and right ends, and a head 2b that fits into an opening on one end side of the peripheral body portion 2a. First, the configuration of the circumferential trunk portion 2a will be described. Reference numeral 3 denotes an outer valve opening formed on the upper surface of one end, and a hopper 5 is detachably attached to the outer valve opening 3. Reference numeral 6 denotes a discharge port formed on the lower surface of the one end. The discharge port 6 faces the outer valve opening 3, and a seal member 7 including a cylindrical discharge nozzle can be screwed into the discharge port 6. Mounted on. The outer cylinder 2 having the head 2b has a required length and is detachably fixed to the upper horizontal plate 1a. The outer valve opening 3 and the discharge port 6 are singular in this embodiment. The shapes of the outer valve opening 3 and the discharge port 6 are, for example, circular.

(5) Inner cylinder 11 of the quantitative discharge device X
In this embodiment, the inner cylindrical body (inner valve) 11 is rotated by the driving force of one driving source 21, and a predetermined amount of powdery body or solid matter b is passed through the outer valve opening 3 from the hopper 5. It is a fixed quantity cylinder which is taken in and discharged to the outside through the discharge port 6.

  Therefore, the inner cylinder 11 exhibits the function of the inner valve with respect to the outer cylinder 2 corresponding to the valve body. Therefore, one inner valve opening 12 that selectively communicates with the outer valve opening 3 and the discharge port 6 of the outer cylinder 2 is formed at the insertion tip (left in the drawing) of the inner cylinder 11.

  By the way, the inner cylindrical body 11 of the present embodiment has a long cylindrical main body 11a and a short cylindrical rear end 11b that can be engaged with and disengaged from the long cylindrical main body and encloses a connecting support described later. The short cylindrical rear end portion 11b is always urged in a direction to engage with the rear end portion of the long cylindrical main body 11a by the elastic member 4 provided on the drive source side.

  In other words, the valve member V of the present embodiment includes an outer cylinder 2 as an outer valve having an outer valve opening 3 and a discharge port 6, and an inner valve as an inner valve rotatably incorporated in the outer cylinder. The cylinder 11 and an extrusion operating body (piston) 18 having a sliding portion 18a incorporated in the inner cylinder and having a follower moving rod 19. When the operating rods 19 and 20 are connected to each other, the valve member V is easily connected when the valve member V is pushed in the horizontal direction with respect to the taper 46b of the locking portion 46 of the connection support 41. When removing the valve member V, for example, if the valve member V is slightly lifted, the engagement relationship between the valve member V and the connection support 41 is easily eliminated.

  Here, with reference to FIG.1 and FIG.2, the engagement relationship of the long cylindrical main body 11a and the short cylindrical rear end part 11b is demonstrated. One or a plurality of engaged portions (notch grooves) 13 are formed on the joining end surface of the rear end portion of the long cylindrical main body 11a. Accordingly, one or a plurality of engaging portions (projections) that are engaged with and disengaged from the engaged portion 13 are formed on the joining end surface of the short cylindrical rear end portion 11b. The elastic member 4 of the present embodiment is positioned between the first support plate 17a provided on the upper surface of the upper horizontal plate 1a of the stationary member 1 and the outer wall surface of the short cylindrical rear end portion 11b. It is wound around the cylindrical shaft portion 14 a of the driven gear 14.

  Moreover, with reference to FIG. 1, the engagement relationship of the cylindrical shaft part 14a of the driven gear 14 and the short cylindrical rear-end part 11b is demonstrated. FIG. 1 is a schematic explanatory view in which the driven gear 14 and the inner cylinder 11 are integrally assembled. The driven gear 14 has a plurality of engaged portions (notched portions in the axial direction) 15 on the outer peripheral wall of the cylindrical shaft portion 14a. Therefore, the short cylindrical rear end portion 11 b has a plurality of engaging portions (projections) 16 that engage with the engaged portion 15 at the edge of the shaft hole.

  The driven gear 14 is disposed between the first support plate 17a and the second support plate 17b so as to be loosely fitted to the drive operating rod 20 and mesh with the drive gear 23. The second support plate 17b is provided on the upper surface of the upper horizontal plate 1a of the fixed member 1 so as to face the first support plate 17a. When the drive gear 23 on the output shaft 22 side is rotated by the drive force of the drive motor 21, the driven gear 14 and the inner cylinder 11 are rotated simultaneously.

  Thus, while the inner valve opening 12 of the inner cylinder 11 communicates with the upper outer valve opening 3, the lower discharge port 6 is closed, while the inner valve opening 12 communicates with the discharge port 6. The outer valve opening 3 is closed.

(6) Detection means S1 for the inner cylinder 11
Above the upper horizontal plate 1a of the fixed member 1, a detection means S1 for the inner cylinder 11 is disposed via a second support plate 17b. This detection means S1 detects the rotational position of the inner cylinder 11. As the detection means S1, one using the Hall IC principle, one using a light emitting element and a light receiving element, or the like can be appropriately employed. In the present embodiment, a plurality of magnets are respectively fixed to appropriate portions of the outer peripheral wall of the driven gear 14, while a Hall element is employed as the detection means S <b> 1 of the fixed side member 1.

  Therefore, when the inner cylinder 11 is rotated "180 degrees" by the driving force of the driving source 21 and one magnet faces the detecting means S1, the detecting means S1 picks up the "N pole" magnetic flux of the magnet and The rotational position of the inner cylinder 11 can be output to the control unit that does not.

(7) Extrusion actuator 18
The push-out operating body 18 has a sliding portion 18 a at the tip end incorporated in the inner cylinder 11. When the sliding portion 18a is retracted to a predetermined position (for example, at the maximum discharge amount), the predetermined volume chamber a is formed. On the other hand, when the sliding portion 18a is advanced to the predetermined position, the predetermined volume chamber a on the distal end side of the inner cylinder 11 is formed. It has the function of extruding the powdery material and solid matter b that have fallen inside.

  In order to easily set or remove the valve member V from the fixed side member 1 for the purpose of cleaning the valve, replacing parts, etc., the operating rod of this embodiment is “divided into two parts” at appropriate points. That is, one is a follower actuating rod 19 of the push-out actuating body 18 constituting the valve member V, and the other is a drive actuating rod 20 on the drive source side slidably disposed on the fixed member 1.

  By the way, the drive operating rod 20 penetrates the short cylindrical inner cylinder 11b, the driven gear 14, the support plates 17a and 17b, etc., which are disposed at predetermined positions of the fixed side member 1, and in this embodiment “long” It is a cocoon-shaped screw body.

  Then, the push-out actuating body 18 integrally connected to the drive actuating rod 20 is driven by the same driving motor 21 through the clutch 34 of the clutch mechanism Y provided on the fixed side member 1 (an example). It is provided so as to reciprocate in the axial direction of the motor 21. Therefore, the drive source 21 for the fixed quantity dispensing apparatus X will be described.

(8) Drive source 21
The drive motor 21 as a drive source is horizontally provided on the lower surface side of the upper horizontal plate 1a via a pair of left and right bearing plates 24 and 25. The left bearing plate 24 supports the base side of the output shaft 22 and serves as a motor mounting plate. On the other hand, the right bearing plate 25 supports the protruding end of the output shaft 22. Therefore, the output shaft 22 of the drive motor 21 is supported in a stable state. A drive gear 23 that meshes with the driven gear 14 is fixed to the output shaft 22 of the drive motor 21. The drive gear 23 cooperates with the output shaft 22. Further, a transmission gear (second drive gear) 26 that is opposed to the drive gear 23 with a required interval is fixed to the output shaft 22. Therefore, the transmission gear 26 also cooperates with the output shaft 22.

  The transmission gear 26 meshes with a cylindrical threaded body (second driven gear) 27 that meshes with a threaded portion 20 a formed on the drive operating rod 20. Therefore, when the cylindrical threaded body 27 is rotated in the forward direction and the reverse direction by the driving force of the drive motor 21, the push-out operating body 18 reciprocates in the inner cylindrical body 11 via the drive operating rod 20.

  The cylindrical threaded body 27 is sandwiched between a second support plate 17b and a mounting frame 1c fixed to the upper surface of the upper horizontal plate 1a with a predetermined interval. The cylindrical screw body 27 rotates in a stable state at a predetermined position.

(9) Detection means S2 for the push-out operating body
A plurality of detection means S2 for the push-out actuating body 18 are arranged on the case-like mounting frame 1c in order to detect the origin (starting) position of the push-out actuating body 18, the forward end position of the push-out actuating body, and the like. A limit switch is used as an example of the detection means S2. The index or magnet 38 for the detecting means S2 is provided via the engaging portion 20b of the drive operating rod 20.

(10) Clutch mechanism Y
Meanwhile, a plurality of engaged portions (small holes, small grooves, etc.) 23a, 26a are formed on the opposing surfaces of the drive gear 23 and the transmission gear 26. The clutch 34 constituting the clutch mechanism Y is engaged with and disengaged from the engaged portions 23a and 26a.

The components of one clutch mechanism Y will be described. Reference numeral 31 denotes a clutch driving means (for example, a solenoid) installed horizontally on the upper surface of the lower horizontal plate 1b. Reference numeral 32 denotes an operating rod of the solenoid 31, and 33 denotes an upward engaging arm fixed in an orthogonal state to the distal end portion of the operating rod 32.
A clutch 34 is provided on the output shaft 22 of the drive motor 21 so as to be slidable in the axial direction, and is selectively coupled to the drive gear 23 or the transmission gear 26. The clutch 34 according to the present embodiment is a block body that looks like an H-shape in a step view and has a plurality of engagements engaged with and disengaged from the engaged portion 23a of the drive gear 23 on one vertical plate. Pins are provided.

  On the other hand, the other vertical plate is provided with a plurality of engaging pins that engage with and disengage from the engaged portion 26a of the transmission gear 26. The upper end portion of the engagement arm 33 described above is located between the vertical plate 35 and the vertical plate 36.

  Therefore, when the operating rod 32 of the solenoid 31 extends, the clutch 34 slides in a direction approaching the drive motor 21, and the left vertical plate 35 is coupled to the drive gear 23. On the other hand, when the operating rod 32 of the solenoid 31 contracts, the clutch 34 slides away from the drive motor 21, and the right vertical plate 36 is coupled to the transmission gear 26. Therefore, the inner cylinder 11 of the valve member V can be rotated by the driving force of one drive motor 21 via the clutch mechanism Y, and the push-out operating body 18 incorporated in the inner cylinder 11 is reciprocated. Can do.

(11) Action of the fixed amount dispensing device If an operating means (start switch) (not shown) is operated, the operating rod 32 of the solenoid 31 contracts, for example. When the operating rod 32 moves to the right, the clutch 34 slides in the same direction and is coupled to the transmission gear 26.

  Therefore, when the drive motor 21 starts (forward rotation), the push-out operating body 18 moves backward to a predetermined position (a set value of the discharge amount) via the cylindrical screw body 27 that meshes with the transmission gear 26. One of the detecting means S2 for the operating body 18 detects the backward position of the pushing-out operating body. When the push-out actuating body 18 moves backward, the push-out actuating body 18 stops at a predetermined position, so that a predetermined amount of powder or solid matter b falls into the inner cylinder.

  Next, when the operating rod 32 of the solenoid 31 extends, the clutch 34 slides on the output shaft 22 in the same direction and is coupled to the drive gear 23. At this time, the engagement pin 35 a of the vertical plate 35 of the clutch 34 is engaged with the engaged portion 23 a of the drive gear 23.

  Therefore, when the drive motor 21 is activated, the inner cylinder 11 rotates a predetermined amount (for example, 180 degrees) via the driven gear 14 that meshes with the drive gear 23. At this time, the pushing operation body 18 rotates together with the inner cylinder 11. Since the engagement portion 19a at the rear end portion of the push-out operation body 18 is engaged with the recessed engagement portion 46 of the connection support tool 41, the push-out operation body 18 is in a stable state with the inner cylinder body. 11 and rotate. The rotational position of the inner cylinder 11 is detected by the detection means S1. When the inner cylinder 11 rotates by a predetermined amount, one inner valve opening 12 moves downward and communicates with the discharge port 6 of the outer cylinder 2 (see FIG. 14).

  Therefore, the powdery substance or solid substance b in the inner cylinder 11 starts to fall from the discharge port 6. At this time, the operating rod 32 of the solenoid 31 returns (shrinks), and the drive motor 21 can rotate in the reverse direction. Accordingly, the pusher 18 is advanced to a predetermined position by the transmission power of the transmission gear 26. As a result, the powdery or solid matter b in the inner cylinder 11 is pushed out by the sliding portion 18a of the push-out actuating body 18 (see FIG. 13). Thereafter, the operating rod 32 of the solenoid 31 extends. Then, since the driving force of the driving motor 21 is transmitted to the driving gear 23, the inner cylinder 11 rotates a predetermined amount again.

  As described above, the inner cylindrical body (inner valve) 11 is rotated by the driving force of the driving source 21 and takes in a predetermined amount of powder or solid matter b from the hopper 5 through the outer valve opening 3. And it discharges outside via the discharge port 6. On the other hand, the push-out operating body 18 reciprocates in the axial direction by the driving force of the driving source 21 through the clutch mechanism Y and the engagement / disengagement structure Z of the operating rod. Next, the engagement / disengagement structure Z of the operating rod will be described.

(12) Working rod engagement / disengagement structure Z
With reference to FIG. 10, the engagement / disengagement structure (hereinafter referred to as “engagement / disengagement structure Z”) of the operating rod of the quantitative discharge device will be described. The engagement / disengagement structure Z of the present invention is simply pointed out. The follower operating rod 19 of the valve member V that can be detached from the fixed side member 1 and the drive on the side of the drive source 21 disposed integrally with the fixed side member 1. This is a connection structure with the operating rod 20. In this embodiment, the valve member V itself is connected to the drive operating rod 20 of the fixed side member 1 so that it can be removed from the fixed side member 1. The reason why the valve member V itself is connected to the drive operating rod 20 and removed from the drive operating rod 20 is that the members constituting the valve member V are easy to disassemble. Therefore, the structural member can be cleaned.

  The connection support 41 is pivotally supported on the drive operating rod 20 in a “one-handed manner” while being constantly biased in a predetermined direction by the spring member 43. The specific structure of the connecting support 41 includes a left and right mounting pivot plate 44 having a pair of left and right shaft holes 44 a for the horizontal shaft 42 at the upper end, and a distal end portion of these pivot plates 44. The vertical plate portion 45 has a circular shape, and a catch-like locking portion 46 that is provided in a projecting state at the lower end of the front surface of the vertical plate portion 45.

  In addition, regarding the components of each part of the connection support 41 made of metal or hard resin, the left and right pivot plates 44 in the vertical state are respectively adapted to the left and right side walls of the tip of the drive operating rod 20. The vertical plate portion 45 has a vertical pressing surface 45a so that it can exert a sufficient pressing function with respect to the vertical tip surface of the driven moving rod 19. In addition, on the upper surface of the locking portion 46, an engagement recess 46a is formed to engage and disengage the engagement portion 19a formed in a trapezoidal shape such as a ball trapezoidal shape or a truncated cone shape. Further, a taper 46b is formed at the tip of the engaging recess 46a so as to be in sliding contact with the engaging portion 19a when connected. In addition, as shown in FIG. 11, a projecting spring support 47 is provided at the lower end of the inner surface of the vertical plate 45. Further, the inner surface of the vertical plate portion 45 is in contact with the upper end surface of the drive operating rod 18.

  In other words, the horizontal shaft 42 that pivotally supports the connection support 41 is located at the upper end of the mounting pivot plate, while the spring member 43 that urges the connection support 41 to the horizontal position is connected to the horizontal shaft 42. Located on the lower side of the support. One end of the spring member 43 is supported by the spring support 47 of the connection support 41, and the other end is attached to a spring end support 20 c projecting from the lower surface of the tip of the drive operating rod 20. .

  In the above configuration, when the valve member V is connected, when the valve member V is pushed into the taper 46 b of the locking portion 46 of the connection support 41, the connection support 41 is connected to the follower moving rod 19 of the valve member V. It is pressed by the taper of the engaging portion 19a and rotates in a direction in which the locking portion 46 is lowered with the horizontal shaft 42 as a fulcrum. When the engaging portion 19 a of the slave operating rod 19 slips over the taper 46 b of the connection support 41, the connection support 41 is restored by the spring force of the spring member 43. As a result, the engagement portion 19a of the valve member V is automatically locked to the dish-shaped locking portion 46 of the connection support 41. On the other hand, when removing the valve member V, for example, if the tip of the valve member V is lifted, the upper end of the vertical plate 45 of the connection support 41 is supported by the upper end surface of the drive operating rod 20. Or since the latching | locking part 46 is formed in the dish shape, the engagement relationship of the valve member V and the connection support tool 41 can be canceled easily. In FIG. 1, c is a cup.

  Referring to FIG. 3, the inner valve opening 12 is formed in a long hole shape with respect to the circular outer valve opening 3. In other words, the inner valve opening 12 formed in a part of the peripheral wall of the inner cylinder 11 is formed in a long hole shape in the longitudinal direction on the distal end side of the inner cylinder 11. Thus, when the inner valve opening 12 is formed in the shape of a long hole, the size and shape of the fitted portion 51 must naturally correspond to the size and shape of the inner valve opening 12.

Further, in the present embodiment, the fitted portion 51 having a concave cross section is integrally fixed to the distal end side of the inner peripheral wall of the inner cylindrical body 11, but as shown in FIG. 51 may be integrally formed on the inner peripheral wall of the inner cylinder 11. Moreover, the shape of the to-be-fitted part 51 can also be formed in cross-sectional V shape, for example according to the kind of powdery material or solid substance. On the other hand, the shape of the protruding fitting portion 52 of the push-out operating body 18 can also be made into a single or a plurality of arm shapes depending on the type of powder or solid.
The configuration of the power transmission means on the drive source side and the number of drive sources are not essential matters of the present invention.

  The present invention is mainly manufactured in the pump industry, and is used, for example, in the service industry such as foods that are provided to customers by subdividing powders and solids.
