This has a scraping shaft supported by a swing arm on the take-out side of the fresh tea managing machine, whereby the fresh tea leaves sent in a stacked state to the take-out end side of the fresh tea managing machine are provided. The end wall surface is effectively scraped off evenly. However, although the actual product to which this mechanism is applied is a relatively large device and is not so limited in terms of space, in the case of a small machine that requires more strict and efficient use of space, such a device is conventionally used for such a scraping. Instead of using a mechanism for dropping, simply drop the tea leaves from the take-out end of the tea fresh leaf management device, install a vibrating conveyor at the drop point, and replace the fresh tea leaves on the conveyor to be transferred to the next process. Was.

However, even with such a vibrating conveyor, a sufficiently large space for receiving the fresh tea leaves falling from the fresh tea leaf managing machine is required, and in this respect, there is room for pursuing further space saving. In addition, when fresh tea leaves fall into a nodular form when falling on such a vibrating conveyor, they are sent to the next process without being sufficiently loosened, or the fresh tea leaves are placed on the lower side of the slat conveyor-like move floor There were problems such as being involved.

As a result, both ends are guided and held.

A take-up drum 44 is provided at the upper end of the container body 2 as a member for raising and lowering the shutter body 40. A take-up handle 46 is provided at the end of a drum shaft 45 of the take-up drum 44. At the same time, a balancer 47 is provided on the drum shaft 45 so that the winding operation can be performed lightly. That is, the balancer 47 is composed of a wire 47A wound around the drum shaft 45 and a spring 47B stretched between one end of the wire 47A and the frame 5 of the container body 2, and helps the spring 47B to tend to pull. Then, it is configured to be lightly wound.

Further, a rod-shaped stopper 48 is provided near the lower side of the winding drum 44.
8 is a cover 49 provided so as to surround the winding drum 44.
Of the reinforcing bars 42 of the shutter sheet 41 and the free-end reinforcing bars 42A.
The configuration is such that the interval is smaller than the thickness of B and wider than the thickness of the intermediate reinforcing bar 42C, and the limits of the feeding and winding of the shutter sheet 41 are set respectively.

The present invention has the above-described structure, and operates as follows. First of all, tea fresh leaf management machine 1
In storing the fresh tea leaves A in the above, the fresh tea leaves A are moved from above onto the move floor 20 in the container body 2 by an input device provided above the fresh tea leaf management machine 1 and capable of facing the input section at an appropriate position. To At this time, if it is not necessary to move the tea leaves A to the next step,
Alternatively, when it is necessary to prevent the movement, first, the shutter body 40 of the take-out part closing device 4 is operated to make the shutter sheet 41 close the take-out side of the container body 2.

That is, as shown in FIG. 7 (a), the shutter sheet 41 is fully fed out from the winding drum 44, and its free end side reaches a position where the free end side substantially contacts the move floor 20 in the container body 2. It is set to a hanging state. At this time, in the limit state of the extension, the movement of the reinforcing bar 42 is stopped in a state where the base reinforcing bar 42A of the reinforcing bar 42 cannot pass through the gap between the stopper 48 and the cover 49. It is.
Further, the reinforcing bars 42 provided at appropriate intervals are held in such a state as to be fitted on the guide rails 43 at both ends thereof, so as to receive the lateral pressure of the accumulated fresh tea leaves A. At this time, the wire 47A of the balancer 47 is wound around the drum shaft 45, and the spring 47B is in an extended state.

In this state, when an appropriate amount of fresh tea leaves A are accumulated in the container main body 2 and it is necessary to move the same to the next step, the move floor 20 is moved and shown in FIG. The following operation is performed. First, the shutter sheet 41 in the shutter body 40 is opened, and the operation of the extracting device 3 is started. Actually, it is desirable that the operation of the extracting device 3 be started prior to opening the shutter body 40 immediately.

First, the take-out part closing device 4 is provided with a shutter body 40.
The take-up drum 44 is rotated in a direction in which the shutter sheet 41 is taken up by, for example, manually operating the hoisting handle 46, and the take-up drum 46 is taken up. And at the time of the winding completion Ri scratching in a state where the free end portion reinforcing bar 42B in the shutter seat 41 can not pass through the gap between the stopper 48 and the cover 49, the winding stop position is restricted. At this time, the winding load is the balancer 4
7, since the spring 47B is extended and tends to be urged in the contracting direction itself, the spring 47B is always urged somewhat in the winding direction with respect to the drum shaft 45 of the winding drum 44. The winding is made very light.

In this state, when the fresh tea leaves A appear at the take-out end of the container body 2, the take-out device 3
As a result, the front end accumulation surface of the
After being scraped by 0a, it is sent to the next step. Here, the movement of the scraping shaft 30 will be described. The driving force of the motor M in the drive unit 34 is appropriately transmitted to the lower scraping shaft 30II to rotate the same.
This rotation is transmitted to the upper scraping shaft 30I via the chain 36. On the other hand, a crank arm 37 is provided at both ends of the upper scraping shaft 30I, which is connected to the upper fixed shaft 38 as an example via a connecting rod 39, so that the upper scraping shaft 30I As a result, they move up and down. With this movement, the entire lifting frame 32 supporting the upper scraping shaft 30I is moved up and down. As a result, the lower scraping shaft 30II and the drive unit 34 mounted on the lifting frame 32 are both substantially vertical as a whole. It will move up and down in the direction.

Accordingly, as an example, two scraping shafts 3 are provided.
0I and 30II move in the vertical direction with the rotation, and evenly scrape the end face on the take-out side of the collected fresh tea leaves A to drop them on the transfer conveyor for transferring the fresh tea leaves A to the next step. It is. In addition, as can be understood from the above description, the present invention is characterized in that the space required for installing the scraping shaft 30 does not protrude from the container body 2. Various modifications of are possible. For example, even when the scraping shaft 30 is swung, space saving can be achieved if the swing arm is provided on the container body 2 side.

[0024]

Since the present invention has the above-described configuration, the apparatus 3 for extracting fresh tea leaves A rotates while moving the scraping shaft 30 in the vertical direction to scrape the fresh tea leaves A.
This is taken out, so that effective tea fresh leaves A can be taken out in a small space.
