JP2574098Y2 - Quantitative distribution device for tea leaves to hopper of tea making machine - Google Patents

Description

[Detailed description of the invention] [Industrial application field] This invention distributes tea leaves, which have completed the middle rubbing process in the tea making process, to a plurality of hoppers provided in a fine rubbing machine which is the next process. It concerns the device.

[Conventional technology]

Regarding a hopper provided on a fine rubbing machine and a device for distributing tea leaves to the hopper, Japanese Utility Model Publication No. 61-8024, Japanese Utility Model Publication No. 5
5-26825 and JP-A-63-141548.

[Problems to be solved by the invention]

The refiner is composed of a plurality of kettles, and it is necessary to accurately measure and distribute the amount of tea leaves to be fed into each kettle.
In general, the hopper installed on the elaborating machine is the actual sho 61-80
As shown in FIG. 24, each hopper is provided with a weighing mechanism using a balance method, and the weight is set by a weight.

In order to make the amount of tea leaves to be put into each kettle constant, it is very difficult to adjust the weight of each hopper one by one.

Japanese Utility Model Publication No. 55-26825 shows that the weighing mechanism is in one place and is distributed after weighing, but the tea leaves put into the weighing hopper are stopped at a predetermined value and the conveyor is weighed to a certain amount. It is very difficult to do this, and there is variation between weighings.

Also, since the weighed tea leaves are dropped on the subsequent distribution conveyor at once, the tea leaves overflow from the conveyor and have not been put to practical use.

In the weighing mechanism of the balance system, since the weight is set by the weight, the weight must be changed at the place where the weight is provided, and the weight cannot be set by remote control.

[Means for solving the problem]

In the present invention, a storage tank 13 of tea leaves also serving as a transport machine is provided, and the tea leaves after the middle rubbing process are temporarily received here, and a fixed amount delivery device 15 is provided in this storage tank 13, and a certain amount of tea leaves is provided. It is possible to send out.

Further, the whole of the storage tank 13 is constantly measured by the weight sensor 24, and the amount of the extracted tea leaves can be measured from the decrease amount of the tea leaves in the storage tank 13. Preliminarily set the weight of tea leaves to be charged in one pot, and when the amount of reduction reaches the set value, temporarily stop feeding and separate the tea leaves for one pot, and dispense it to the hopper provided on the elaborating machine by the distribution conveyor The problem was solved by providing a device for feeding tea leaves.

〔Example〕

 An embodiment will be described with reference to FIG.

13 is a tea storage tank of this invention, the bottom of which is a belt conveyor. Reference numeral 15 denotes a water wheel-shaped scraping device.
The entire storage tank 13 is suspended from a load cell 23 which is a weight sensor.

The load cell 23 is connected to a load cell converter 24 to convert the weight into an electric signal, and is connected to a controller 25. Storage tank 13
The upper part faces the transport machine 14, and the delivery end is a belt conveyor.
Arrange 12

The fine crushers 9 and 10 are provided with fine hoppers 1 to 8 at positions corresponding to the respective kettles.
11 moves left and right on rail 26, to each tea leaf hopper,
Distribute the weighed tea leaves.

Each of the tea leaf hoppers 1 to 8 has a tea leaf confirmation sensor 19.
Is provided to detect whether the hopper is empty or full. This may be a limit switch as shown in JP-A-63-141548. Reference numerals 20, 21 denote tea leaf confirmation sensors (for example, photoelectric switches, proximity switches, etc.) provided on the distribution conveyor 11, which move together with the distribution conveyor 11.

Reference numeral 22 denotes a tea leaf confirmation sensor provided near where tea leaves fall from the conveyor 12 to the distribution conveyor 11.

[Action]

The operation will be described based on an embodiment. The tea leaves after the middle rubbing process are sent by the transporter 14 and are put into the storage tank 13. When the weight of the storage tank reaches the upper limit set by the controller 25, the transport machine 14 stops.

The amount of tea leaves that can be stored in the storage tank 13 depends on
It suffices to have only a few for 8). The distribution conveyor 11 has a controller 25
Moves on the rail 26 according to the instruction, stops on the specified fine rubbing hopper, and puts the tea leaves.

The lower surface of the storage tank 13 is a conveyor, and the stirrer 15 stirs the tea leaves and feeds a fixed amount of tea leaves little by little. The tea leaves sent out by the fixed amount are conveyed by a conveyor, and put into a fine hopper by a distribution conveyor 11.

The controller 25 sets the input amount of the fine hopper, and when the weight of the storage tank 13 decreases by the set value, the feeding of the tea leaves is stopped. On the conveyor 12 and the distribution conveyor 11, the tea leaves sent out by the set value of the fine rubbing hopper remain and are transported as they are. When the photoelectric switches 20 and 21 detect that the tea leaves being carried by the distribution conveyor 11 are gone, the distribution conveyor moves to the next fine hopper. Each fine hopper has a tea leaf confirmation sensor 19, so that the fine hopper containing the tea leaves passes through.

The delivery of the tea leaves from the storage tank 13 is stopped when the tea leaves for one cup of the fine rubbing hopper are delivered, but starts to be delivered again after a certain time. For this reason, a blank portion indicated by A occurs on the conveyor 12, and this is confirmed by the tea leaf sensors 20 and 21 so that it is possible to detect that the supply of one cup has been completed.

The sensor 22 confirms that no tea leaves remain on the distribution conveyor 11, operates the conveyor 12, and controls so that the tea leaves are not duplicated on the conveyor. As soon as the delivery of the tea leaves from the storage tank 13 is stopped, the transport machine 14 is operated immediately and the tea leaves are put into the storage tank 13.

〔effect〕

According to this invention, the amount of tea leaves to be put into each of the fine hoppers is measured at one location in the storage tank 13, so that the same amount can be distributed to any fine hopper.

It is not necessary to adjust the weighing mechanisms provided in the fine-mass hopper and to set the input amount as in the related art. Weight sensor
23 Since the weight can be detected at one location and the amount of the fine hopper to be charged can be set by the controller 25, automatic control can be easily performed by remote control.

The tea leaves sent by the conveyor 14 from the middle rubbing process are not a fixed amount, but a relatively large amount of tea leaves are sent in an uneven state, so, as in Japanese Patent Publication No. 63-141548, to the fine rubbing hopper as it is When the tea leaves are carried and weighed by the fine rubbing hopper, the weighing is full and the dosing becomes inconsistent even if the charging is stopped. In addition, it often spills from a distribution conveyor or the like during transportation.

In this invention, the conveyor is once received in storage tank 13 so
The amount of tea leaves sent at 14 may be uneven. Since a certain amount of tea leaves are fed out little by little from the storage tank 13, accurate measurement of one cup of the fine rubbing hopper can be performed. Also, there is no spillage on the way from the distribution conveyor.
