[Object of the Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tea making device having a semi-cylindrical fixed kneading drum, such as a tea making rough kneader and a tea making machine.
It is related to this, especially suitable for management such as maintenance and inspection
The proposed structure is proposed .

[0002]

BACKGROUND OF THE INVENTION For example, a tea-making coarse kneader is provided with a rotating kneading hand and a sweeping hand in a semi-cylinder-shaped fixed kneading cylinder whose upper side is opened. In particular, a steaming process is provided between the kneading hand and the kneading cylinder. The finished tea leaves are kneaded, and further kneaded and dried. However, due to such a processing form, tea astringent, scrap-like tea leaves, etc. stick to the duck plate on the inner surface of the kneading drum. Is something
It is managed to remove these regularly.
In this method, for example, a front control door is provided on the front side of the rough kneader, and this is opened to remove and wash the tea astringency in the kneading drum. Since there is a rubbing hand, a squeezing hand, and a rotating shaft supporting the rubbing hand, it is extremely difficult to carry out the work such as removing the tea astringent and cleaning the rear part.

For this reason, it is attempted to improve the workability of maintenance management by making it possible to open the vicinity of the rear, which is relatively hard to reach from the front of the device, as in Japanese Utility Model Publication No. 4-36625, "a tea leaf coarse kneader capable of opening the bottom of the mass." Has also been done. This one has been devised in the opening and closing direction especially when opening near the rear of the kneading cylinder. Specifically, when opening and closing a part of the kneading cylinder, a hinge is provided below and the kneading cylinder is partially opened. In this case, it is proposed that the inner surface of the kneading cylinder is directed upward to facilitate the cleaning work and the like.

With such a construction, the workability is improved accordingly because the inner surface of the kneading cylinder is certainly open and the inner surface of the kneading cylinder faces upward. It was pointed out that even if the tea leaf pieces etc. were removed from the duck plate stretched on the inner surface of the kneading plate, they would be clogged again between the duck plates and the workability in removing them would be poor. . For this reason, there has been a demand that it is difficult to throw away a foreign matter or the like on the inner surface of the crumpling plate in terms of workability even in a form in which it is naturally eliminated immediately. In addition, with such a door-opening form, when an operator puts his / her body through the opening of the kneading cylinder to wash the fixing part of the kneading cylinder, this door-opening part tends to be an obstacle, The workability was not always good.

[0005]

[Technical Items Attempted to Develop] The present invention has been made in view of such a background, and it is possible to easily remove foreign substances such as tea astringent pieces and tea leaf pieces removed from the inner surface of the kneading plate, and kneading This is an attempt to develop a tea-making device that makes it easier to clean the inside of the body, etc., and also improves the safety of the opening / closing operation of the management door plate or the opening / closing operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to illustrated embodiments. Reference numeral 1 indicates a tea making coarse kneader which is an example of a tea making apparatus to which the present invention is applied, and the basic structure thereof is a conventionally known one or a structure which will be improved in the future. Needless to say, a leaf striking device that performs substantially the same operation or a combined machine that simultaneously performs the rough rubbing action and the leaf striking action can be applied.

The structure of this is roughly described. A kneading cylinder 3 having a semi-cylindrical shape whose upper side is opened is fixedly attached to the machine frame 2 in a recumbent state. This one is formed by sticking a large number of rod-shaped duck plates 3a on the inner surface thereof in the state of close contact in the longitudinal direction. Further, a hot air cylinder 5 is provided on the upper side portion thereof, and hot air for drying or heating the tea leaves A is supplied from here. Further, a rotary shaft 6 which is appropriately rotatably attached to the machine frame 2 is attached in a recumbent state about the arc center of the kneading cylinder 3, and a kneading hand 7 and a sweeping hand 8 are attached to this one at appropriate intervals. It should be noted that the upper side of the kneading cylinder 3 is also a box-shaped space that is almost sealed, and this is referred to as a disturbing cylinder 9.

The kneading drum 3 is provided below with a take-out door 10 for taking out the processed tea leaves A, and below the kneading drum 3 is provided with a take-out conveyor 11 formed by applying, for example, a vibration conveyor. A front control door 13 is provided on the front surface of the tea making and kneading machine 1. In this embodiment, the front control door 13 is provided.
Is configured so that the front panel of the agitation drum 9 can be opened. Of course, the front management door 13 may not be provided at this portion, but may be provided at a position near the front of the kneading cylinder 3, for example.

As a characteristic configuration of the present invention, the rear management door 15 is constructed as a part of the kneading cylinder 3. That is, the range from the lower side to the rear side of the kneading cylinder 3 is made openable like a door at the hinge 16, and the hinge 16 is provided at the upper edge of the rear management door 15. Therefore, the free end side of the rear management door 15 is arranged below the kneading cylinder 3. The hinge 16 can be pulled out with the hinge pin left on one side. When a so-called flag hinge is used, the entire rear management door 15 can be removed.

Further, the rear management door 15 may be provided with a biasing means 17 configured to constantly bias the rear management door 15 toward the open side. The urging means 17 need only act to urge the rear management door 15 to the open side, and may be constituted by a cylinder 171 as shown in FIGS. Specifically, the cylinder body 171a of the cylinder 171 is rotatably supported by the fixed bracket 18a, while the slider 171b of the cylinder 171 is fixed to the bracket 18b provided on the outer surface of the rear management door 15. Therefore, it is assumed that the cylinder 171 itself has a constant contraction tendency.

The cylinder 171 may also have a simple spring built-in, for example.
Shifting the slider with air or oil,
Alternatively, an appropriate cylinder such as one that shifts the slider by an electric screw shaft can be used.

As another embodiment of the biasing means 17, a tension spring 172 may be used as shown in FIG. 5, or a torsion coil spring 173 provided near the hinge point may be used. Reference numeral 19 is a crescent-shaped lock for closing the free end of the rear management door 15 in a closed state. As a matter of course, this lock itself may be applied with any suitable conventionally known configuration that is operated by remote control or the configuration that will be developed later. Also reference numeral 2
Reference numeral 0 is a catch for holding the management door 15 after the door is opened (see FIG. 4).

The tea making apparatus of the present invention has a specific structure as described above, and when the kneading cylinder 3 is maintained and inspected by the rear management door 15, the lock 19 is first released. The rear management door 15 is opened. On this occasion,
In the case where the cylinder 171 serving as the urging means 17 is applied, if the cylinder 171 that operates by obtaining appropriate power is used, the power is input to open the rear management door 15. Of course, when the spring or the like is elastically urged, the free end side is manually opened to the position where it is flipped up as shown in FIGS. At this time, the biasing means 17
Since the rear management door 15 is provided, the rear management door 15 can be flipped up by an extremely light operation even in a manual operation. Of course, if the flipped-up state cannot be maintained by itself, or in order to make this safe and secure, the open / closed state is maintained by the catch 20.

After this, in order to remove the tea astringent and other foreign matter adhering to the rear management door 15 itself, a work such as rubbing it off with a brush, a spatula, etc. is carried out as is conventionally done. To do. At this time, the foreign matter and the like accumulated between the duck plates 3a on the inner surface of the rear management door 15 fall downward each time they are removed, because this surface is directed almost downward.
Efficient work can be performed again without clogging between the duck plates 3a.

On the other hand, when the rear management door 15 is opened, the operator can insert the upper body up to the back of the kneading cylinder 3 through the opening 3b, so that the inside of the kneading cylinder 3 cannot be cleaned. Easy to do without. By the way, in the case of the conventional type of opening to the lower hinge type, the management door is located directly below the opening after the opening state, and because of this, the operator slips the upper body etc. into the kneading cylinder from the opening. It was difficult to take such a posture that the work could be done on the inner surface of the kneading cylinder in the opened opening, but the work on the fixed part was not always easy. After the completion of such management work as cleaning, maintenance, inspection, etc., the rear management door 15 is returned to its original state, the opening 3b is closed, and the lock 19 is put into the operating state.

[0020]

Since the present invention has the above-mentioned structure, the management work of the tea making apparatus can be performed relatively easily.
Specifically, since the inner surface of the rear management door 15 is slightly downward from the vertical direction, foreign substances can be removed efficiently. Further, since the rear management door 15 does not exist below the opening 3b, it becomes easier for a worker to approach the opening 3b, and cleaning of the inside of the kneading cylinder 3 is easy. Also, the biasing means 17
By providing the rear management door 15, the rear management door 15 can be easily operated even though it is flipped upward, and the rear management door 15 does not drop at once, and the work can be performed in a state where safety is ensured.
