[The purpose of the device] [Industrial applications]

 The present invention relates to an improvement of a tea making and kneading machine, and in particular, a novel tea leaf residue preventing structure and a tea leaf residue preventing structure for preventing the tea leaves being processed from being left partially after being pushed from the kneading machine to the surroundings. It relates to parts.

[0002]

[Background of device]

 The tea making and kneading machine operates a kneading bowl having a kneading body that swirls above the surface of a circular kneading machine, and the tea leaves put into the kneading bowl are kneaded between the kneading body and the kneading board. This process is normally performed at the stage when the middle kneading process is completed. At this time, conventionally, during the kneading action, the tea leaves moved to the outside so that some of the tea leaves were removed from the turning range of the kneading bowl, and sometimes remained without being taken into the kneading bowl again. . During such processing, the tea leaves that have been removed and left in the surrounding area are of different quality from the tea leaves that have undergone the rubbing process, so even if these removed tea leaves are processed properly, I couldn't mix it with the tea leaves I received, so I had to throw it away or process it separately. In order to eliminate such waste, workers take measures such as returning to a kneading bowl each time a certain amount of tea leaves that have been removed are collected, and such monitoring work during processing work is performed. It was extremely troublesome and dangerous to put it back and forth.

[0003]

[Prior art]

 For this reason, attempts have been made so far to eliminate leakage of tea leaves around the kneading machine during processing, but this was not always sufficient. For example, Japanese Utility Model Publication No. 56-39980 "Tea kneading machine with a sweep-out prevention wall", Japanese Utility Model Publication No. 12-2826 "Tea manufacturing machine", Japanese Utility Model Publication No. 10-5963 "Tea kneading machine", Japanese Utility Model 45. -14 No. 4959 "Techniques for continuous kneading of tea leaves" have already been disclosed, but in terms of the shape of the portion around the kneading plate where the tea leaves tend to accumulate, there are stepped depressions in the dark circle. There is a tendency for tea leaves to accumulate in this area, so it cannot be a sufficient countermeasure.

[0004]

[Technical items we tried to develop]

 The present invention has been made in view of such a background and the problems of the prior art, so that tea leaves in the middle of processing can be uniformly kneaded without remaining around the kneading machine. This is an attempt to develop a structure for preventing residual tea leaves in the tea making and kneading machine.

[0005]

Is. These ideas are intended to achieve the above object.

[0011]

[Function of the device]

 When the kneading machine is in operation, the kneading bowl makes a turning motion on the kneading board to knead the tea leaves between the kneading body in the kneading bowl and the kneading board. At this time, the tea leaves tend to leak from the lower part of the kneading bowl, but since there is no space around the kneading plate where the tea leaves can remain, the tea leaves were temporarily removed near the outer circumference of the kneading plate. Even so, it is taken back into the kneading bowl again and continues to be kneaded.

Further, when the residue prevention piece at the periphery of the bowl is made of an elastic material, the contact with the lower end portion of the bowl is performed without impact, and the smooth operation is performed.

[0013] Furthermore, for example, when the residual prevention pieces arranged in an annular shape around the periphery are dividedly formed, it becomes easier to carry out the removal work, and if only partially damaged, replace only that portion. Returns to normal operating conditions.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. Reference numeral 1 is a kneading machine according to the present invention. The outline of the structure of the kneading machine is as follows. A kneading machine 3 is provided on the upper surface side of a square frame 2 and further eccentric to the kneading machine 3. Further, a kneading bowl device 4 that swivels is provided, a driving device 5 for the kneading bowl device 4 and a take-out device 6 for taking out the tea leaves A after kneading are provided, and further, a residual prevention structure 10 which is a characteristic member of the present invention. Is provided.

First, the frame 2 is made of an appropriate steel material in the shape of a rectangular frame, has a kneading plate 3 on the upper surface thereof, and has the drive device 5 and the take-out device 6 mounted below it. Further, the kneading board 3 is one of the members directly responsible for the kneading action, and has a detachable lid-like take-out opening / closing part 30 at the center, and its periphery is inclined so as to be slightly lower toward the center. A disk-shaped member having an inclined massaging surface 31 and the like, and a kneading protrusion 32 is formed in a converging spiral shape on the take-out opening / closing section 30 and the inclined massaging surface 31. Around the ring-shaped kneading plate 3, a decorative plate 33 having a height slightly higher than the height of the peripheral part of the kneading plate 3 is provided, and the upper surface of the rectangular frame 2 is closed. By the way, the decorative plate 33 is, for example, divided into four parts and assembled.

Further, the kneading bowl device 4 directly responsible for the kneading action together with the kneading board 3 is mainly composed of a cylindrical bowl body 40 having an open top and a kneading body 41 provided therein. The bowl body 40 has a bowl arm 42 protruding in three directions around the bowl body 40 as an example, and is connected to at least two opposing points to a crank arm 51 that rotates by receiving power from the drive device 5, whereby a crank is provided. Upon receiving the rotation of the arm 51, the kneading bowl body 40 eccentrically moves on the kneading board 3. It should be noted that all of the crank arms 51 may be driven, or the eccentric turning motion is possible even if at least one of the crank arms 51 is driven. Then, from the other one of the kneading bowl arms 42, a rod-shaped kneading body support portion 43 extends so as to cross over the kneading bowl body 40, and thereby the kneading body 41 is hung and the weight is reduced. A weight 44 is provided. Incidentally, the kneading pressure during the kneading action is set by the weight of the kneading body 41 and the load of the weight 44. Further, a brush 45 is provided in an annular shape at the lower end of the kneading bowl main body 40, and this is attached to the kneading bowl main body 40 in a state of being loosely held as an example.

Next, the drive device appropriately reduces the rotation of the drive motor M, which is a prime mover, as described above, and transmits the rotation to the crank arm 51. The take-out device 6 is, for example, a vibrating conveyor or the like applied, and is configured so that the receiving side end portion faces the lower end of the kneading machine 3 and the processed tea leaf A can be taken out from the side portion of the frame 2. Become. The present invention can be applied to such a basic conventionally known kneading machine or a kneading machine which will be improved later to prevent the tea leaves A from remaining.

The residual prevention device 10 will be described in detail below with reference to FIGS. This is mainly composed of a residue prevention piece 11 which is a tea leaf residue prevention component, and this residue prevention piece 11 extends as a whole from the outer peripheral portion of the kneading machine 3, that is, from the outer peripheral portion of the inclined massaging surface 31 to the outer peripheral side. This is an annular member as described above, and has a corner portion closing portion 12 and a return guide portion 13 continuous to the outside thereof when viewed in the cross-sectional direction. Of course, the corner closing portion 12 and the return guide portion 13 may be integrally formed as shown in FIG. 4 (a) or may be separately formed as shown in FIG. 4 (b). Good. Further, the residual blocking piece 11 may be a ring-shaped integral member, or may be appropriately divided into four parts in the circumferential direction as shown in FIG. In addition, when it is divided into four, the decorative plate 33 is often divided into four as described above, which is convenient because both can be unitized. Of course, in the present invention, it does not matter if such a decorative plate 33 does not exist.

Further, reference numeral 14 is a fixing bolt hole provided in the residual prevention piece 11, which enables the residual prevention piece 11 to be fixed to the decorative plate 33 or the kneading board 3 with bolts or the like. The material of the residue prevention piece 11 is not particularly limited as long as it has a shape capable of closing the corners that are likely to occur around the kneading board 3, but synthetic rubber, silicone rubber, silicone resin having elasticity, etc. It is preferable to be composed of the elastic material. Further, in order to positively obtain the elasticity thereof, it is possible to take a means such as providing a cushion void 15 inside when viewed in the cross-sectional direction of the residual prevention piece 11 as shown in FIG. 4 (c).

The present invention has the configuration as described above and operates as follows. That is, when operating with the residue prevention piece 11 attached around the massaging plate 3, it is discharged to the outside as if swept out from the brush 45 at the lower end of the massaging device 4 as shown in FIG. Even if there is a tea leaf A, since the gap for leaving the tea leaf A is blocked by the residue prevention piece 11, the movement is such that it is taken in again by the brush 45 of the kneading bowl device 4 that has swirled next. , Always receives the kneading in the kneading bowl main body 40. The tea leaf A, which tends to escape to the outside, tends to move further outward, but a return guide portion 13 beyond the repose angle of the tea leaf A is formed in a wall shape further outside the corner closing portion 12. Therefore, it falls from the periphery of the kneading plate 3 back to the inside and is taken into the kneading bowl main body 40 to be processed again.

[0021]

[Effect of device]

 Since the present invention has the above-described structure, tea leaves that are further out of the operating range of the kneading bowl body 40 during the kneading process can be returned to the kneading action position in the kneading bowl body 40 again. A sure kneading is done. In addition, since there is no residual tea leaves A inside, work that is premised on the occurrence of such residual tea leaves is unnecessary, and safe management can be achieved. Further, since all the tea leaves A put into the kneading machine 1 are uniformly processed, it is possible to prevent the quality deterioration due to the mixing of the tea leaves due to the insufficient kneading. Furthermore, if the residual prevention piece 11 for providing the residual prevention structure 10 is supplied as a separate component, the existing kneading machine 1 can be improved.
