  In this embodiment, the groove closer to the pinion gear 16 (tooth 20A side) is the first groove 25, and the groove far from the pinion gear 16 is the second groove 26. As shown in FIGS. 7 and 8, the second groove 26 has an inclined surface whose bottom surface is highly inclined so that the groove gradually becomes shallower from the lower edge of the upper through hole 28 (upper edge of the groove 26) downward. After 26 A is formed, the lower end of the inclined surface 26 A is a flat surface 26 B that maintains the height of the bottom surface, and the lower end is formed into a step shape by the lower through-hole 29. The lower end of the flat surface 26B and the upper edge of the lower through-hole 29 serve as an engaging portion guide portion 40 that is inclined upward at a predetermined angle.

  In addition, as shown in FIG. 7, the first groove 25 has an inclined surface 25A whose bottom surface is highly inclined so that the groove gradually becomes shallower from the upper edge of the lower through hole 29 (lower edge of the groove 25) upward. Is formed, the upper end of the inclined surface 25A is a flat surface 25B maintaining the height of the bottom surface, and the side end (the end opposite to the pinion gear 16 side) is stepped by the upper through hole 28. It is made into a shape. Further, the upper end of the flat surface 25B and the upper edge of the upper through-hole 28 are formed as an engaging portion guide portion 41 that is formed to incline upward at a predetermined angle.

  With the above-described configuration, the pinion gear 16 is rotated by the reciprocating operation of the rack 20, and thereby the powder material is carried out by a predetermined amount, and the operating member 102 is rotated by the reciprocating operation of the rack 20, thereby opening and closing the opening / closing member 101. The operation of moving and thereby opening and closing the discharge port member 106 will be described. 3, 7, and 8 show the unloading standby state of the rack 20.

  9 to 12, among the three racks 20..., The rack 20 located at the center causes the engaging portion 23 (not shown in FIGS. 9 to 11) to be pushed by the downward pushing operation of the rack 20. The state which moved to the upper part of the 1st groove | channel 25 is each shown.

  In the powder raw material unloading standby state, as shown in FIGS. 3, 7, and 8, and as described above, one end of the rack 20 is locked to the lower end portion of the rack 20, and the other end is the lower standing surface 4 </ b> B of the front plate portion 4. The upper end of the fixing member 24 fixed to the upper front end of the fixing member 24 attached to the front surface of the front plate portion 4 is held in a state of projecting a predetermined dimension above the insertion hole 5A of the connection surface 5 of the front plate portion 4. .

  At this time, the engaging member 22 is abutted against the lower edge of the long hole 21 of the rack 20 and is regulated so as not to be further raised by the urging force urged in the direction in which the coil spring 38 is always retracted. ing. Further, in this state, the engaging portion 23 that is always urged rearward by the urging force of the fixing member 24, that is, the rack 20 side, is an abbreviation of the second groove 26 that is located away from the pinion gear 16 side. It is in a state of being locked in the lower through hole 29 of the rack 20 located below. In this unloading standby state, the pressing portion 20B of the rack 20 is in contact with the inclined portion 102B of the operation member 102 from above as described above.

  When carrying out the powder raw material, the upper part of the rack 20 is pushed downward against the urging force of the coil spring 38 (forward operation). Since the pressing portion 20B pushes the operation member 102 from above by the downward pushing operation of the rack 20, the operation member 102 rotates so that the upper side moves forward as shown in FIGS. Thereby, as shown in FIG. 12, the opening / closing member 101 moves forward to open the raw material discharge port 13.

  On the other hand, due to the pushing operation of the rack 20, the rack 20 is positioned on the pinion gear 16 side along the inclined shape of the upper edge of the lower through hole 29 by the engaging portion 23 located in the lower through hole 29. The track is switched to the groove 25 side.

  As a result, the lower portion of the rack 20 is moved away from the pinion gear 16 by the guide of the engaging portion guide portion 40 of the engaging portion 23, and the meshing between the teeth 20A of the rack 20 and the pinion gear 16 is released. It is assumed that

  While maintaining the state in which the engagement between the pinion gear 16 and the teeth 20A of the rack 20 is released by the further pushing operation (forward operation) of the rack 20, the engaging portion 23 enters the first groove 25. The engaging portion 23 that is constantly biased toward the rack 20 by the leaf spring (fixing member 24) rises along the inclined surface 25A formed at the lower end of the first groove 25, and is flat. To 25B. In the process in which the engaging portion 23 rises along the inclined surface 25A, since the first groove 25 and the second groove 26 are partitioned by the partition wall 27, the engaging piece 23 is Movement from the inside of the first groove 25 to the second groove 26 is restricted.

  In this state, when the pushing operation of the rack 20 is released, the pinion gear 16 and the teeth 20A of the rack 20 are not engaged with each other, and the engaging portion 23 is moved to the same track by the biasing force of the coil spring 38. That is, it returns to the original state by following the first groove 25.

  Here, as described above, the coil spring 38 holding the rack 20 has an upper end positioned closer to the shaft side of the pinion gear 16 than the contact position between the rack 20 and the pinion gear 16 as shown in FIG. The urging member attached to the urging member attaching portion (not shown) of the upper front end of the fixing member 24 attached to the front surface of the lower standing surface 4B of the portion 4 and the lower end of the urging member attached at a position further away from the pinion gear 16 Locked to the portion 37.

  As a result, the engaging portion 23 that reaches the flat surface 25B is located above the second groove 26 that is open when it exceeds the partition wall 27 that partitions the first groove 25 and the second groove 26. And the track of the engaging portion 23 is switched from the first groove 25 to the second groove 26.

  At this time, since the engaging portion 23 is provided by being urged by the fixing member 24 from the lower upright surface 4B side toward the rack 20 side, the upper portion penetrates in a state where the engaging portion 23 is released from the height position of the flat surface 25B. Projects backward from the hole 28. Thereby, since the engaging part 23 is urged | biased by the side which protrudes back, it will be in the state from which return to the flat surface 25B which comprises the 1st groove | channel 25 was controlled.

  The engaging portion 23 is locked in the upper through hole 28 located above the second groove 26 formed at a position away from the pinion gear 16, so that the entire rack 20 is pinned by the coil spring 38. The pinion gear 16 is engaged with the teeth 20A of the rack 20 in this state.

  In this state, the engaging member 22 abuts on the upper edge of the long hole 21 of the rack 20, and further pushing operation is restricted. Therefore, when the operator releases the pushing operation of the rack 20, the force against the urging force of the coil spring 38 is released, so that the lower end of the rack 20 is lifted by the urging force of the coil spring 38 urged in the retracting direction. The rack 20 moves backward (ascends).

  At this time, the engaging portion 23 enters the second groove 26 formed at a position away from the pinion gear 16, and the engaging portion 23 that is constantly biased toward the rack 20 side is the second groove 26. 26 descends along an inclined surface 26A formed at the upper end of the plate 26 and reaches a flat surface 26B. Then, the rack 20 is further pulled up by the urging force of the coil spring 38, and the engaging portion 23 positioned at the lower end of the flat surface 26B falls into the lower through hole 29, as shown in FIGS. Return to the unloading standby state (initial state).

  The pinion gear 16 meshed with the teeth 20 </ b> A of the rack 20 is rotated by the amount meshed by the movement of the rack 20 by the returning operation by the biasing force of the coil spring 38 of the rack 20. Accordingly, the spiral body 15 provided coaxially with the pinion gear 16 is rotated by a predetermined amount in the direction in which the powder raw material is discharged, and the powder raw material filled between the rotary blades 15B of the spiral body 15 is conveyed to the raw material discharge port 13. And discharged from the raw material discharge port 13. The powder raw material discharged from the raw material discharge port 13 is placed on a topping material (not shown) stored in the topping material storage unit 3 via the discharge port member 106, an opening 106A formed on the lower surface thereof, and the powder guide chute 103. To be paid out.

  Further, as described above, the teeth 20A of the rack 20 are not formed to the lower end of the side surface of the rack 20, and the lower end is a flat surface 20C. Therefore, when the pinion gear 16 reaches the lower end of the teeth 20A ( 13), the rotation of the pinion gear 16 stops. In this state, the rack 20 has not risen completely (that is, has not returned to the unloading standby state (initial state) as shown in FIGS. 3, 7, and 8), and the opening / closing member 101 is still open. It is in a state (FIG. 14).

  That is, the rotation of the spiral body 15 stops before the rack 20 is fully raised. Thereby, the carrying-out operation | movement of a powder raw material is stopped. At this time, the opening / closing member 101 is still open (FIG. 13). Thereafter, the rack 20 further rises and returns to a predetermined unloading standby state (initial state).

  As described above, in this embodiment, the rack 20 is reciprocally held on the front plate portion 4 (main body), and when the rack 20 is pushed downward, the rackion 20 cannot be engaged with the pinion gear 16. At the time of the backward movement of 20, by engaging with the pinion gear 16, the spiral material 15 that is coaxially provided with the pinion gear 16 by the reciprocating operation of the series of racks 20 and discharges the powder raw material is discharged. It can be rotated by a predetermined amount in the direction in which the powder raw material can be delivered.

  In this embodiment, the rack 20 is manually moved forward and moved backward by the biasing force of the coil spring 38, whereby the dimensions of the rack 20 (the teeth 20A of the rack 20 are formed) that mesh with the pinion gear 16. Depending on the size of the portion, the spiral body 15 can be rotated by a fixed amount, and a fixed amount of powder raw material can be discharged from the raw material discharge port 13. Therefore, it is possible to discharge a predetermined amount of the powder raw material without controlling the rotation time of the spiral body 15 by using a special motor or the like. Accordingly, a predetermined amount of powder raw material can be discharged without using an electric member, the structure of the entire apparatus can be simplified, and it can be installed even in a place where a power source cannot be secured.

  Further, in the present embodiment, a very small amount, for example, about 0.2 to 0.3 g of powder raw material can be quantitatively carried out by one operation depending on the dimensions of the pinion gear 16 and the rack 20 meshing with the pinion gear 16. . The rack 20 is always urged by the coil spring 38 so as to protrude upward from the upper surface of the connection surface 5 of the front plate portion 4, and is reciprocated by being pushed downward against the coil spring 38. Since movement is possible, the operability can be improved.

  In particular, the opening / closing member 101 is provided to close the raw material discharge port 13 so that the raw material discharge port 13 can be freely opened and closed. It becomes possible to do. Further, as in the present embodiment, even when a plurality of raw material storage containers (three in the left and right in this embodiment) 10 are provided and a plurality of types of powder raw materials are carried out, vibration or the like may occur during the carrying out of the powder raw materials. Due to the inconvenience that other powder raw materials are carried out and mixed, the powder raw materials are carried out due to the impact and vibration applied to the entire apparatus, and the topping material (the container that accepts the powder raw material discharged from the raw material discharge port 13) The inconvenience of soiling the to-be-topped material storage unit 3 and the apparatus installation floor can be solved.

  Further, since the raw material discharge port 13 is opened and closed in conjunction with the reciprocating movement of the rack 20, it is not necessary to separately open and close the opening and closing member 101 when the powder raw material is carried out, and the operability is remarkably improved. Further, as described above, when the rack 20 moves in the direction in which the spiral body 15 is rotated in the direction in which the powder raw material is discharged from the raw material discharge port 13, the opening and closing member 101 is engaged with the open / close member 101. Since it is configured to end before closing 13, the rotation of the spiral body 15 is stopped before the opening / closing member 101 completely closes the raw material discharge port 13. This avoids the inconvenience that the powder material is clogged between the opening and closing member 101 and the material discharge port 13 due to the rotation of the spiral 15 when the opening and closing member 101 closes the material discharge port 13, and smooth carry-out. Can be realized.

  Further, the pinion gear 16 is provided at the distal end portion of the gear member 104 that enters the raw material discharge port 13 and is coaxially connected to one end of the spiral body 15, and the opening / closing member 101 is located around the gear member 104. The gear member 104 is provided so as to be movable in the axial direction, and is moved by the reciprocating movement of the rack 20 to open and close the raw material discharge port 13. Therefore, the raw material discharge port 13 is opened by the opening and closing member 101 in conjunction with the reciprocating movement of the rack 20. It becomes possible to reduce the size of the entire device for opening and closing the door.

  Furthermore, since the operation member 102 that operates by reciprocating movement of the rack 20 and moves the opening / closing member 101 in the axial direction of the gear member 104 is provided in contact with the rack 20 and the opening / closing member 101, the rack 20 can be configured with a simple configuration. The raw material discharge port 13 can be opened and closed by reliably moving the opening and closing member 101 in conjunction with the reciprocating movement.

  Furthermore, since the partition wall 122 of the frame member 111 partitions the region Y where the rack 20 and the pinion gear 16 are present from the region X where the material discharge port is present, it is generated by the operation and meshing of the rack 20 and the pinion gear 16. This eliminates the inconvenience that dust such as abrasion powder is mixed into the powder raw material carried out from the raw material discharge port 13 and the powder raw material adheres to the meshing portion of the rack 20 and the pinion gear 16 to hinder the carrying-out operation of the raw material powder. be able to.

  In the above-described structure of the present embodiment, the opening / closing member 101 is moved in conjunction with the reciprocating movement of the rack 20 to open / close the raw material discharge port 13. The material discharge port is opened according to the fact that the product (the container for receiving the powder raw material discharged from the material discharge port) is placed at the predetermined receiving position, and the material discharge port is opened according to the removal from the receiving position. It is also effective as a blockage. This configuration will be specifically described with an example. For example, the guard 100 is configured to be movable back and forth. In this case, in a state where the topping object is not placed on the topping object storage unit 3, the guard 100 is positioned in the front, the topping object is placed on the topping material storage unit 3, and the guard is placed. It is assumed that the object to be topped can be made to correspond to the lower end opening of each chute 103 described above, which is a predetermined receiving position, by being brought into contact with 100 and moved backward.

  Further, an operation member similar to the operation member 102 of the above-described embodiment is disposed between the guard 100 and the opening / closing member 101. As described above, the operation member places the opening / closing member 101 of the gear member 104 in conjunction with the operation of placing the object to be topped on the object to be topped storage 3 and bringing it into contact with the guard 100 and moving it backward. The raw material discharge port 13 is opened by moving in the axial direction (forward). Then, when the topping object is removed from the above-described receiving position of the topping object storage unit 3 (that is, the position corresponding to the lower end opening of each chute 103), the guard 100 moves in conjunction with the forward movement, The operation member moves the opening / closing member 101 in the axial direction (backward) of the gear member 104 to close the raw material discharge port 13.

  As described above, the raw material discharge port 13 is opened according to the opening / closing member 101 being placed at the predetermined receiving position of the topping material, and the raw material discharge port 13 is closed according to being removed from the receiving position. Even in such a configuration, it is not necessary to separately open and close the opening and closing member 101 when the powder raw material is carried out, and the operability can be improved as in the configuration of the above-described embodiment.

  In this embodiment, the rack 20 is manually moved forward, but may be moved forward by a solenoid, for example. As a result, it is not necessary to control the rotation time of the spiral body 15 as in the prior art, and it is possible to discharge a fixed amount of powder raw material simply by issuing a powder raw material dispensing instruction, thereby simplifying the structure of the entire apparatus. Further, even when the rack 20 is moved by a motor, it is possible to realize the quantitative delivery of the powder raw material without controlling the rotation time by detecting the reciprocating movement of the rack.

  Further, in the present embodiment, the distance from the pinion gear 16 is different, and the rack 20 in which the first groove 25 and the second groove 26 that are continuous at both ends are formed, and the engagement portion 23 described above. When the rack 20 moves forward, the engaging portion 23 moves in the first groove 25 located on the pinion gear 16 side and moves away from the pinion gear 16 when returning. The direction in which the powder raw material is discharged from the raw material discharge port 13 by meshing the pinion gear 16 and the teeth 20A of the rack 20 only when moving backward in the second groove 26 with a simple structure. The spiral body 15 can be rotated only in the direction of rotation.

  In the present embodiment, the first groove 25 and the second groove 26 are provided in the rack 20 and the engaging portion 23 is provided in the fixing member 24. However, the present invention is not limited to this, and the fixing member 24 is not limited thereto. The first groove and the second groove may be formed in the rack 20 and the rack 20 may be provided with an engaging portion. In this case, when the rack 20 moves forward, the engaging portion passes through the groove on the side away from the pinion gear 16, and when returning, it passes through the groove on the side close to the pinion gear 16.

  Further, in this embodiment, when the rack 20 is pushed downward and moves forward, the engaging portion 23 moves in the first groove 25 located on the pinion gear 16 side of both grooves, and the end portion After being pushed in, the engaging portion 23 moves in the second groove 26 at a position away from the other pinion gear 16 when returning by the urging force of the coil spring 38, whereby the rack 20 and the pinion are moved. The helical body 15 is rotated in a direction in which the powder raw material is discharged from the raw material discharge port 13 by meshing with the gear 16. In this case, the rack 20 and the pinion are moved as long as the engaging portion 23 is moved to the end of the first groove 25 that moves during the forward movement and does not move into the upper through hole 28 and further into the second groove 26. It can be set as the structure which does not mesh with the gear 16. FIG.

  Thus, when the rack 20 is moved forward, when the pushing operation is not sufficiently performed until the engaging portion 23 reaches the end portion and falls into the upper through hole 28, the engaging portion 23 is It will move only in the groove | channel 25, and it can be set as the structure which cannot rotate the pinion gear 16. FIG.

  Therefore, unless the rack 20 is pushed to an appropriate position, the powder raw material can be prevented from being carried out. Therefore, the pinion gear 16 is rotated only by a smaller amount than the fixed amount, and a smaller amount of the powder raw material is discharged. It is possible to eliminate the inconvenience.

  Therefore, the user can be urged to push the rack 20 to an appropriate position, and the powder raw material can be released only when the rack 20 is reliably moved by a predetermined amount. Unloading can be ensured.

  In the present application, the following three can be considered as constituent requirements that can be added to the claims.

(Configuration 1 that can be added to claims)
The rack movement restricting means includes first and second grooves that are formed in either the rack or the main body and have different distances from the pinion gear, and an engaging portion provided in the other. And
The two grooves are continuous at the end, and when the rack moves forward, the engaging portion moves in the first groove, and in the backward movement, moves in the second groove. The rack meshes with the pinion gear only when the engaging portion moves in one of the grooves.

  According to this configuration, with a simple structure, the reciprocating movement of the rack can rotate the pinion gear engaged with the rack only in the direction in which the spiral body is rotated in the direction of discharging the powder raw material from the raw material discharge port. it can.

(Configuration 2 that can be added to claims)
The rack is provided so as to protrude from the main body and is urged so as to always protrude by the urging means. The rack can be reciprocated by being pushed into the main body against the urging means. ing.

  According to such a configuration, the rack is moved forward by manually pushing the rack against the biasing means, and the rack is discharged from the main body side by the biasing force of the biasing means by releasing the rack. Can be realized. Thereby, the operativity can be improved.

(Configuration 3 that can be added to claims)
When the rack is pushed into the main body and moves forward, the engaging portion moves in the other groove of the two grooves, and is pushed to the end portion, and then is urged by the urging force of the urging means. When returning, the engaging portion moves in the one groove.

  According to such a configuration, when the rack moves backward, the rack and the pinion gear mesh with each other to rotate the spiral body in the direction in which the powder raw material is discharged from the raw material discharge port. The rack and the pinion gear can be structured so as not to mesh with each other as long as the rack moves to the end in the other groove positioned during the forward movement and does not move into the other groove.

  As a result, when the rack is not moved by a predetermined amount and the engaging portion moves only in the other groove positioned during the forward movement, the pinion gear cannot be rotated and the powder raw material is discharged. It will not be broken. Accordingly, the powder material can be discharged only when the rack is surely moved by a predetermined amount, so that the quantitative delivery of the powder material can be ensured.
