Abstract

To provide a tea-processing vertical bucket conveyor allowing for cleaning a sidewall in conveyance.SOLUTION: A tea-processing vertical bucket conveyor is provided with an endless strap belt in a part of a sidewall of the tea-processing vertical bucket conveyor.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a tea making vertical bucket conveyor installed in a tea making factory.

  In a tea factory, a tea making machine is connected to a tea making machine by a carrying device, and a vertical bucket conveyor for tea making is indispensable for the carrying device. In a conventional tea making vertical bucket conveyor, tea leaves are placed on a bucket, and the bucket is conveyed from the bottom to the top by a substantially vertical conveyor, and a side wall is provided around the conveying portion. (See Figure 9)

  In recent years, it has been a problem to suppress the growth of various bacteria such as general viable bacteria in a tea factory, and it is a problem for producers to control the order of the viable cell count for the tea product produced. Insufficient cleaning of the tea making machine is one of the factors that make the live bacteria grow. In a normal tea making machine, hot air is blown to dry the tea leaves, so that the production of viable bacteria can be suppressed.

  Since the side wall of the vertical bucket conveyor for tea making is closed, the inside of the side wall cannot be visually observed and cleaned, and the residue of conveyance is always adhered, which is unsanitary and may become a hotbed for bacteria. Although it can be washed away with water, the effect could not be confirmed because it was not visible.

  Conventionally, there is a cleaning lid for cleaning the bottom end of the lowermost end of the vertical tea making bucket conveyor as in Patent Document 1, and after cleaning tea, the cleaning lid is opened to clean the bottom. In some cases, the bottom surface of the housing is cleaned by attaching leaf dredge as in Patent Document 2. The conventional technique is to clean the bottom end, not the side wall.

Japanese Utility Model Publication No. 60-103118 Japanese Utility Model Publication 57-126413

  In both Patent Documents 1 and 2, only the lowermost end of the vertical tea making bucket conveyor could be cleaned. Needless to say, it is necessary to clean the lowermost end, but it was also desired to clean the other side walls during transportation. Therefore, an object of the present invention is to clean the side wall during transportation.

A first means of the present invention is a vertical bucket conveyor for tea making, characterized in that an endless belt is provided on a part of a side wall of the vertical bucket conveyor for tea making.
A second means of the present invention is the first means, wherein only the endless belt is allowed to pass through and an opening is provided.
A third means of the present invention is the first or second means, wherein the endless belt is provided with a driving means.
A fourth means of the present invention is the above-mentioned first, second or third means, wherein means for removing deposits on the endless belt is provided.

  By moving the belt of the belt conveyor provided on the side wall of the device of the present invention, it is possible to bring the inside of the side wall to the outside for visual inspection, to monitor the adhesion of tea leaves, and to move the dirty belt to the outside. The surface can be cleaned directly. Since the dirty portion is taken out of the vertical tea making bucket conveyor for cleaning, the inside of the vertical tea making bucket conveyor can be cleaned without being contaminated.

  According to the second aspect of the present invention, the opening surface of the original side wall can be reduced, and the tea leaves are not spilled from the opening surface. According to the third aspect of the present invention, the belt can be automatically moved by the driving means and can be easily cleaned. According to the fourth aspect of the present invention, by simply rotating the endless belt, it is possible to automatically remove the deposits attached to the endless belt.

FIG. 3 is an explanatory sectional view showing a vertical bucket conveyor for tea making. FIG. 4 is a cross-sectional explanatory view showing a vertical bucket conveyor for tea making. FIG. 5 is a partial detailed explanatory view showing an embodiment of the vertical bucket conveyor for tea making. FIG. 6 is a partial detailed explanatory view showing an example of a vertical bucket conveyor for tea making. FIG. 7 is a partially detailed explanatory view showing the time course of the vertical tea making bucket conveyor. FIG. 8 is an explanatory view showing a tea making line. FIG. 9 is an explanatory view showing a conventional vertical bucket conveyor for tea making.

  1 to 3 show an overall view of a vertical tea-making bucket conveyor. The tea making vertical bucket conveyor receives tea leaves 10 from the lower receiving port 7 and discharges the tea leaves 10 from the upper discharging port 8. A belt conveyor 2 is provided above and below the interior, and a plurality of buckets 1 for mounting tea leaves 10 are attached to a belt 2A of the belt conveyor 2. The belt conveyor 2 inside is driven by a motor 5. The periphery of the belt conveyor 2 with the bucket 1 is surrounded by a side wall 6. An opening is provided in a part of the side wall 6, and an endless belt 12 is provided. The endless belt 12 may occupy only a part of the side wall or most of the side wall. At this time, as in the embodiment shown in FIG. 5, when only the portion through which the endless belt 12 passes is the opening (A), (C), or (D), or the portion where the endless belt 12 substitutes for the side wall. Any of them may be used, such as the case where all the openings are formed (B). Further, although the endless belt belt 12 that moves up and down is used in the embodiment of FIG. 5, the endless belt belt 12 that moves horizontally as in the embodiment of FIG. 6 may be used.

  The endless belt 12 has a pulley 13 at its end, and the endless belt 12 can be easily rotated by pulling it by hand. Thereby, the endless belt 12 can be rotated anytime and to any extent. A motor (not shown), which is a driving means, may be connected to the pulley 13 of the endless belt 12 and driven by the motor. By driving with a motor, the endless belt 12 can be rotated more easily than pulling by hand. It is possible to drive the motor regularly or to rotate the endless belt 12 constantly at an ultra-low speed.

  The movement of the vertical tea-making bucket conveyor 21 of this embodiment will be described. The tea leaf 10 that has entered from the lower receiving port 7 is scooped up by the bucket 1, the tea leaf 10 is placed on the bucket 1, and the bucket 1 moves upward as the belt conveyor 2 moves. At this time, tea leaves protruding from the bucket 1 may adhere to the inside of the side wall 6, or tea leaves falling from above may adhere to the inside of the side wall 6. As shown in FIG. 7, when the adhered matter such as the tea leaves 10 adheres to the endless belt 12 having no adherence at first, the endless belt 12 is rotated to move the surface of the belt 2A on which the tea leaves 10 adhere. The tea-making vertical bucket conveyor 21 is moved to the outside, and the soiled belt 2A is cleaned on the outside of the tea-making vertical bucket conveyor 21. As for the cleaning method, from various methods such as (a) scraping with a removing means such as a scraper 17 or a brush, (b) wiping with a cleaning tool 16 such as cloth, (c) spraying water or alcohol, air, etc., Select it depending on how dirty it is. If a scraper 17 or a brush is fixed to the side wall 6 of the vertical tea-making bucket conveyor 21, it can be easily used when the endless belt 12 is automatically moved by a motor.

  Since the apparatus as described above cleans the outside of the side wall 6 of the vertical tea making bucket conveyor 21, it does not drop the removed dust on the inside of the side wall 6 of the vertical tea making conveyor 21 and makes a vertical tea making machine. Even while the tea leaves 10 are being conveyed by the bucket conveyor 21, cleaning can be performed without stopping the vertical tea-making bucket conveyor 21.
