  As shown in FIGS. 1 to 3, each stirring unit 5 includes an arm 37 as a support and a scraping blade 39 provided at the tip of the arm 37.

  The arm 37 is supported with respect to the rotary shaft 35 by a clamp portion 43 provided on the base end side. At the tip of the arm 37, a bracket 45 for mounting the scraping blade 39 is provided. The bracket portion 45 is set at an angle of θ with respect to the axial center of the rotation shaft 35. In the present embodiment, as shown in FIG. 2, the angle formed between the rotating shaft and the blade surface is a set angle θ = about 30 °. However, the set angle θ is arbitrary.

  The clamp portion 43 is formed of a coupling having a structure in which the rotation shaft 35 is sandwiched. A coupling base 43 a is fixed to the tip of the arm 37. The coupling lid portion 43b is fastened and coupled to the coupling base portion 43a by a bolt 43c with the rotation shaft 35 interposed therebetween.

  Fastening and fixing of the stirring unit 5 to the rotating shaft 35 is performed by the fastening and coupling of the coupling base 43 a and the coupling lid 43 b sandwiching the rotating shaft 35.

  The bracket portion 45 is attached to the tip end side of the arm 37 in the axial direction. The bracket portion 45 is configured to be included in the arm 37, and constitutes a support portion together with the arm 37.

  As shown in FIG. 5, the bracket portion 45 integrally includes a base 45a and a protrusion 45b.

  The base 45a has a basic cross-sectional shape that is substantially circular, and an inclined surface 45aa is formed on the front and rear in the rotational direction of the rotary shaft 35. The inclined surface 45aa gradually reduces the cross-sectional shape of the base 45a from the arm 37 toward the protrusion 45b.

  The base portion 45 a includes a fitting portion 45 ab at the base end, and is fitted and coupled to the tip end of the cylindrical arm 37. The fitting connection is fixed by welding, bonding, press-fitting or the like.

  The protrusion 45b is formed in a droplet shape in cross section along the rotation direction of the rotary shaft 35. The droplet shape of the protrusion 45 b is a shape that becomes thinner on the side of the tip 45 ba of the protrusion 45 b.

  The protrusion 45b is provided with a support surface 45bb on both outer sides that opposes the attachment portion of the scraping blade 39. Both sides of the protrusion 45b mean both outer sides in the axial direction of the rotation shaft 35 and the connecting pin 73 in the protrusion 45b having a single shape which is not a bifurcated shape.

  The protrusion 45 b has an insertion hole 45 bc. The insertion hole 45 bc is arranged such that the axis is parallel to the axis of the rotation shaft 35.

  In addition, the protrusion 45b can also be formed in a bifurcated shape. In this case, both sides of the projection 45b mean both of the bifurcated both outer side and both opposite sides.

  The protrusion 45b has the effect described later in either case of the single shape or the bifurcated shape of the embodiment.

  The scraping blade 39 is inclined and arranged on the inner peripheral surface of the heating container 3 so as to be inclined backward with respect to the normal rotation direction a. That is, the scraping blade 39 is set to be inclined such that the blade tip 61a in contact with the inner peripheral surface of the heating container 3 moves in the forward direction in the forward rotation.

  As shown in FIGS. 3, 4, and 6 to 8, the scraping blade 39 is a blade supporting plate 59 to which a blade portion 61 made of resin or the like is attached and attached to the bracket portion 45 of the stirring unit 5. And is supported by the rotary shaft 35 side of the heating container 3. For attaching the blade portion 61 to the blade support plate 59, a pressing body 63 and a fastener 65 are used.

  The blade support plate 59 is formed of stainless steel, resin or the like, and is provided with a pair of attachment portions 69 on the center side of the edge portion 67 a on the base end side with respect to the blade support portion 67 at the tip.

  An inclined surface 67 b that faces the back surface of the blade portion 61 is formed at the tip of the blade support portion 67.

  The blade support portion 67 is curved so that the edge portion is slightly arcuate when viewed from the back side of FIG. The curved shape of the blade support portion 67 corresponds to the blade portion 61. The blade support part 67 has a left and right length close to the blade part 61 for attaching the blade part 61. A total of four attachment holes 67c are formed in the blade support portion 67 on both sides of the central portion in the length direction.

  The main body of the pair of mounting portions 69 is formed in a donut shape when viewed from the axial direction of the rotation shaft 35, and protrudes from the edge portion 67a via the connecting portion 69a. The attachment portion 69 is disposed on the support surfaces 45bb on both sides of the protrusion 45b and is supported by the protrusion 45b by the coupling pin 73.

  The mounting portion 69 includes an insertion hole 69 b. The insertion hole 69 b is for inserting the coupling pin 73 and is formed to be equal to the outer diameter of the coupling pin 73. The equivalent to the outer diameter is such that the coupling pin 73 can be easily inserted and pulled out manually through the insertion hole 69b. It is also permissible to form the insertion hole 69b slightly larger in diameter than the coupling pin 73 and to provide a backlash between the two.

  A stopper projection 69 c is provided on the outer peripheral surface of the pair of attachment portions 69. The stopper protrusion 69 c abuts on the inclined surface 45 aa and restricts the rotation range of the scraping blade 39 with respect to the bracket part 45. The regulation of the rotation range can be changed depending on the position of the stopper projection 69c with respect to the mounting portion 69. A substance to be stirred can be coated in a thin film on the inner surface of the cylindrical portion 25 of the heating container 3 at the time of inversion due to the restriction of the rotation range, or the inner surface of the cylindrical portion 25 can be left with a certain thickness.

  Furthermore, the lumpy substance can be crushed by the gap between the inner surface of the cylindrical portion 25 of the heating container 3 and the blade tip 61a.

  The stopper protrusion can also be provided on a positioning portion 65b described later of the fastener 65.

  The blade portion 61 is made of resin and is made of a wear resistant resin, and the blade back surface is overlapped and fixed to the mounting surface of the blade support plate 59. The blade portion 61 has four through holes 61b facing the four attachment holes 67c.

  The blade portion 61 is formed in a substantially rectangular shape when viewed from the front surface in the forward rotation direction a. The blade portion 61 is set at an angle of θ with respect to the axial center of the rotary shaft 35 via the bracket portion 45, so that the blade tip 61a can scrape off the inner peripheral surface of the heating container 3 in a set state. It is formed in a slight arc shape.

  The pressing body 63 is formed of stainless steel or the like, and four pin bodies 63a are provided corresponding to the four mounting holes 67c. At one end of the pin body 63a, a blade opposing plate 63b is integrally formed as a blade opposing portion, and at the other end of the pin body 63a, a constricted portion 63c is provided. The other end of the pin main body 63a is a head 63d. The outer surface of the head 63d is formed into a tapered shape by taper or rounding.

  The blade facing plate 63 b is formed in a long plate shape along the blade portion 61. The blade facing plate 63 b faces the surface of the blade portion 61 and sandwiches the blade portion 61 with rattling or in close contact with the blade support portion 67.

  The pin bodies 63 a are respectively inserted into the mounting holes 67 c and the through holes 61 b that correspond in position, and the narrow portions 63 c protrude from the back surface of the blade support plate 59.

  The pressing body 63 can be formed independently by dividing the blade facing plate 63b according to each pin body 63a. The constricted portion 63c can also be configured as a whole between the head 63d at the tip of each pin body 63a and the blade facing plate 63b.

  The blade opposing plate 63b only needs to be capable of pressing the blade surface of the blade portion 61, and its shape can be freely set to a rectangular shape, a disk shape, an elliptical shape, or the like.

  The fastener 65 is detachably attached to the constricted portion 63 c, and the pressing member 63 presses and fixes the blade portion 61 to the blade support portion 67. By adjusting the length of the pin main body 63a, the presser can make the presser of the blade portion 61 between the presser body 63 and the blade support portion 67 loose.

  The fasteners 65 are formed of stainless steel, resin or the like, and are provided in pairs. The fastener 65 is formed in a symmetrical shape, and integrally includes a slide plate 65a and a positioning portion 65b.

  Each slide plate 65 a is formed to have a dimension that extends over two left and right attachment holes 67 c in the longitudinal direction of the blade support portion 67. In the slide plate 65a, pairs of an insertion hole 65aa and a slide hole 65ab are respectively formed at two places. The insertion hole 65 aa is for penetrating the head portion 63 d side of the pin main body 63 a, and is formed to have a diameter slightly larger than the outer shape of the pin main body 63 a. The slide hole 65ab is continuous with the insertion hole 65aa and formed along the slide plate 65a.

  The slide hole 65ab can also form a guide slope toward the far side in the slide direction so as to attract the pin body 63a in the axial direction as it moves.

  In the present embodiment, the guide slope is not particularly formed. Accordingly, it is possible to form a backlash due to the gap between the blade support portion 67 and the blade portion 61, and it is possible to replace the object to be stirred by breathing action inside and outside between the blade support portion 67 and the blade portion 61. It becomes.

  In this case, the rattling between the blade support portion 67 and the blade portion 61 is not limited to that due to the conscious gap formation by the dimension setting of each part, but includes that due to dimensional tolerance.

  In the case of attraction and fixing by forming the guide slope, the dimension between the tip of the head 63 d of the pin main body 63 a and the blade facing plate 63 b is the sum of the blade 61, the blade support 67 and the slide plate 65 a. Slightly smaller than the thickness dimension of

  With this setting, when the head portion 63d side of the pin main body 63a is guided and guided by the guide slope, the pin main body 63a is pulled in, and the wing portion 61 is provided between the tip of the pin body 63a on the side of the constriction portion 63c and the blade facing plate 63b. The blade support portion 67 and the slide plate 65a are fastened and held.

  In the present embodiment, the slide hole 65ab merely engages with the constricted portion 63c of the pin main body 63a in the attached state of the fastener 65, and there is no axial retraction.

  The positioning portion 65b is integrally formed in a donut-shaped flange shape at the end of the slide plate 65a, and includes an insertion hole 65ba. The circular outer diameter of the positioning portion 65 b is smaller than the circular outer diameter of the mounting portion 69, and the insertion hole 65 ba of the positioning portion 65 b is larger than the insertion hole 69 b of the mounting portion 69.

  The positioning portion 65b is bent at the end of the slide plate 65a, and the positioning portion 65b is substantially orthogonal to the slide plate 65a. At the end of the slide plate 65a, a rib 65bb is bent and formed integrally with the positioning portion 65b. A rising portion 65ac is formed at the end of the slide plate 65a to reinforce the coupling between the rib 65bb and the end of the slide plate 65a.

  The positioning portion 65 b of each fastener 65 is disposed on the surface on the opposite side of the attachment portion 69 of the blade support plate 59. This positioning part 65b is arrange | positioned at each support surface 45bb of the both sides of the protrusion 45b, and the coupling pin 73 penetrates. With this arrangement, the positioning portion 65b of the fastener 65 is arranged between the pair of attachment portions 69 and the protrusion 45b that is the support portion.

  In this arrangement state, the connecting pin 73 passes through the through holes 69b and 65ba of the mounting portion 69 and the positioning portion 65b and the through holes 45bc of the projection 45b, and the scraping blade 39 can be detachably attached to the bracket 45 by the connecting pin 73. Combined with

  Accordingly, the scraping blade 39 is rotatable with respect to the arm 37 by the coupling pin 73.

  The coupling pin 73 has a head portion 73a at one end and a lock portion 73b rotatably coupled to the other end. The lock portion 73b is made straight with respect to the coupling pin 73, and the attachment portion 69, the positioning portion 65b, and the projection 45b are penetrated, and after penetrating, the lock portion 73b is rotated to be in a locked state as shown in FIG. The return of the rotation of the lock portion 73b is regulated, for example, by the frictional force around the axis. The operator can rotate the lock portion 73b against the frictional force by hand or through a tool, and remove the lock portion 73 straight from the coupling pin 73.

[Disassembly of scraping blade]
FIG. 9 is a rear view of the scraping blade 39 shown in a state in which the connecting pin is pulled out and the slide plate is pulled in the detaching direction.

  When disassembling the scraping blade 39, the lock portion 73b of the coupling pin 73 is straightened and pulled out toward the head portion 73a.

  The attachment portion 69 and the positioning portion 65b are detached from the protrusion 45b, and the scraping blade 39 is removed from the bracket portion 45.

  Each fastener 65 of the scraping blade 39 is slid on the slide plate 65a, and the slide plate 65a is slid along the slide hole 65ab with respect to the constricted portion 63c of the pin main body 63a. This sliding movement is in the direction of bringing the fasteners 65 closer to each other.

  By this slide movement, the insertion hole 65aa of the slide plate 65a is aligned with the constricted portion 63c of the pin main body 63a. At this time, the rib 65bb of the slide plate 65a can be pinched to apply a force, and the slide movement of the slide plate 65a can be easily performed.

  Each fastener 65 is detached from the pin body 63a. The pin bodies 63a are pulled out of the mounting holes 67c and the through holes 61b, and the presser body 63 is released.

  Therefore, the support of the blade part 61 is lost, and the blade part 61 can be detached from the blade support part 6 of the blade support plate 59.

  In this removed state, the blade support plate 59, the blade portion 61, the presser body 63, and each fastener 65 can be easily washed.

  At the same time, the protrusion 45b remains on the bracket portion 45 remaining on the arm 37 on the rotating shaft 35 side. For this reason, the single-shaped protrusion 45b having a simple external shape other than the bifurcated shape can be easily washed with high-pressure water or the like.

  Although the mounting portion 69 of the blade support plate 59 is bifurcated, the blade support plate 59 is detached from the rotary shaft 35 side, so that the cleaning angle can be easily changed with the blade support plate 59 in hand, making cleaning difficult. There is no.

  After cleaning, the scraping blade 39 can be easily attached to the protrusion 45b again by the reverse procedure.

  Therefore, the scraping blade 39 can be extremely easily disassembled and cleaned without the troublesome operation of loosening or fastening the bolt with a spanner.

[Function of scraping and pressing type heating and stirring kettle]
In the present embodiment, a highly viscous material for producing soot is used as the substance to be stirred.

  When the material is heated and stirred, the split lid 31 of the heating container 3 is removed in advance, and the split lid 31 is accommodated in the lid accommodating portion 17. Then, the material is introduced from the upper opening of the open heating container 3. At this time, the weight sensor 23 detects the input weight of the input material. In this weight detection, it is detected including the removed split lid 31. After the attachment of the split lid 31, the weight detection control during heating and stirring does not require calculation taking into consideration the detachment of the split lid 31; Software can be simplified. Further, since the piping unit 12 is grounded independently to the side of the support frame 15 by the flexible pipe 32, the influence of the weight of the piping unit 12 is suppressed when detecting the weight by the weight sensor 23, and accurate detection Can be done.

  After the material is charged, the split lid 31 is mounted again on the upper opening of the heating container 3, and the drive motor 7 is automatically driven and controlled by the control box 9 with a program installed in advance. By such control, the stirring unit 5 is rotated forward and reverse at predetermined intervals. For example, after normal rotation is performed three times, reverse rotation is performed three times, and this is repeated until the material reaches a target weight by moisture evaporation. However, the number of rotations of forward rotation and reverse rotation can be arbitrarily set according to the material, cooking condition, mixing state, etc. For example, after performing 2 normal rotations, it is also possible to perform 2 reverse rotations. is there.

  When forward rotation and reverse rotation are repeated for each predetermined cycle, rotation of the material in the reverse direction can suppress or eliminate the rotation of the material with the stirring unit 5, and the material can flow.

  At the time of forward rotation, the scraping blade 39 of the stirring unit 5 can scrape the material.

  That is, since the scraping blade 39 is inclined backward in the reverse direction b, scraping between the lower surface of the blade portion 61 of the scraping blade 39 and the inner peripheral surface of the heating container 3 in the normal direction a It slides and rotates while the angle for action forms an acute angle.

  For this reason, the scraping blade 39 scrapes and flows the material so as to separate the material from the inner peripheral surface of the heating container 3. Accordingly, the material is heated and stirred as a whole by mixing the portion heated on the inner peripheral surface of the heating container 3 and the portion not heated inside.

  Further, at the time of forward rotation, the blade tip 61a of the blade portion 61 of the scraping blade 39 is pressed against the inner peripheral surface of the heating container 3 by the resistance of the material, so that scraping can be reliably performed.

  During forward rotation, the stopper projection 69c of the blade support plate 59 is separated from the inclined surface 45aa of the bracket portion 45.

  At the time of reversal, the material can be pressed by the scraping blade 39 of the stirring unit 5.

  That is, the scraping blade 39 receives resistance from the back surface and rotates around the coupling pin 73. This rotation is performed until the stopper projection 69c abuts on the inclined surface 45aa of the bracket 45.

  At the swing position at the time of reversal, a gap is formed between the blade tip 61 a of the blade portion 61 and the inner peripheral surface of the heating container 3.

  In the reverse direction b, the material on the inner peripheral surface of the heating container 3 is guided by the wedge shape between the scraping blade 39 and the inner peripheral surface, and is guided and flowed toward the inner peripheral surface side of the heating container 3 .

  The material which has flowed reaches the gap between the blade tip 61a and the inner peripheral surface of the heating container 3 while being guided by the scraping blade 39, and the blade tip 61a of the blade portion 61 and the inner peripheral surface of the heating container 3 in the gap. And is pressed against the inner peripheral surface of the heating container 3.

  Depending on the gap between the blade tip 61 a and the inner peripheral surface of the heating container 3, the material is reliably applied to the inner peripheral surface of the heating container 3 in the form of a film or a layer.

  By applying the material to be stirred to the inner peripheral surface of the heating container 3 with the scraping blade 39, it is possible to crush the lumpy substance contained in the material to be stirred. The crush effect of the dummy substance can be changed by adjusting the gap between the blade tip 61a and the inner peripheral surface of the heating container 3, that is, the position of the stopper projection 69c with respect to the inclined surface 45aa.

  The applied material is overcoated with the material remaining on the inner peripheral surface at the time of forward scraping. As a result, moisture is transferred from the top coating material to the residual material, and heat transfer to the top coating material occurs, preventing overheating.

  Therefore, the residual material is prevented from being burnt by the moisture transfer and the heat transfer. The residual material is in a fluffed state due to the movement of water, and is easily scraped off in the next forward rotation.

  The application of the material to be stirred to the inner peripheral surface of the material to be stirred is basically in the form of a film or a layer at the time of inversion, but if there is movement of water to the material remaining on the inner peripheral surface, the application state Is not necessarily limited to a membrane or a layer. Therefore, the shape of the gap by changing the shape of the blade portion 61 can also be set freely.

  At the time of the reversal, the material is moved to the gap side as it slides on the back surface of the scraping blade 39 in order to press the material by using the back surface of the scraping blade 39 which was not used at the time of normal rotation. The adhesion retention of the material can be suppressed.

In addition, since the direction of movement is reversed at the time of reversal by forward rotation and reverse rotation and rotational force is applied to the material in the opposite direction, material rotation with the arm 37 of the agitation unit 5 and the rotation shaft 35 can be prevented. In addition, the adhering material can be caused to flow to suppress adhesion retention.
[Modification]
FIG. 10 is a perspective view showing a modification of the fastener. The basic configuration is the same as that of the first embodiment, and the same or corresponding components are denoted by the same reference numerals, and redundant description is omitted.

  The fastener 65 of the second embodiment is configured by only the slide plate 65a without the positioning portion 65b shown in the above embodiment.

  The slide hole 65ab is provided with a guide slope 65ad that faces the back side in the slide direction so as to attract the pin body 63a in the axial direction as it moves.

  In the case of fastening and fixing by forming the guide slope 65ad, the dimensions between the head 65d at the tip of the narrowed portion 63c side of the pin main body 63a and the blade facing plate 63b It is formed slightly smaller than the total thickness dimension with the plate 65a.

  With this setting, when the end of the pin body 63a on the side of the narrowed portion 63c is guided by the guide slope 65ad, the pin body 63a is pulled in, and the blade portion is formed between the head 63d of the pin body 63a and the blade facing plate 63b. 61, the blade supporting portion 67 and the slide plate 65a are fastened and held.

  Therefore, also in the present embodiment, the blade portion 61 can be removed or attached from the blade support plate 59 as in the above embodiment by the slide movement of the slide plate 65a.

  Moreover, since the slide plate 65a does not engage with the coupling pin 73, the blade portion 61 can be removed from the blade support plate 59 while the blade support plate 59 is attached to the projection 45b of the bracket portion 45.

  Therefore, the blade portion 61 can be cleaned more easily.

  In addition, substantially the same effect as that of the above embodiment can be obtained.

[Others]
In the present invention, when the projection 45b as the support portion is formed in a bifurcated manner, a support surface may be provided to make the attachment portion 69 opposite to the inner side with respect to the bifurcated projection.

  In this case, the pair of attachment portions 69 of the blade support plate 59 are disposed on both sides of the bifurcated projection and supported by the bifurcated projection by the coupling pin 73. The positioning portion 65b of the fastener 65 is disposed between the bifurcated projection and the bifurcated mounting portion 69 on both inner sides of the bifurcated projection.

  That is, in this modification, the pair of attachment portions 69 disposed on both sides of the support portion means disposed and attached to the support surfaces on both inner sides of the bifurcated protrusion.

  The advantage of this variation and the variation where the fork attachment parts 69 are disposed on both outer sides of the forked protrusion 45b is a tunnel structure in which the inside of the forked protrusion penetrates in the stirring rotation direction in the assembled state. The object to be stirred passes at the time of operation, the clogging of the object to be stirred at the protrusion is suppressed, and cleaning is facilitated.

  The specific form of the blade support plate 59, the blade portion 61, the presser body 63, and the fastener 65 can be changed variously as long as the scraping blade 39 can be easily disassembled and cleaned.
