Description

DETAILED DESCRIPTION OF THE INVENTION << Object of Invention >><Industrial Application Field> The present invention relates to a sampling device used in a tea making machine.

<Prior art> Conventionally, there is a device that inserts a sampling means into the tea making machine to extract a part of the tea leaves during the tea making process and measures the properties thereof. Based on this, there is a method of making tea by changing the tea making conditions at any time.

<Problems to be solved by the invention> Particularly stable sampling is desired for the sampling device provided in such a tea making machine, but the tea leaves during the tea making process are not completely broken yet and contain a large amount of water. It is easy to form baby nodules. If such a nodule of tea leaves falls directly on the sampling device, the sampling amount varies, and this tends to cause an error in the property investigation. Moreover, the impact of the drop of the baby boom shortens the life of the sampling device.

<Structure of device><Means for solving the problem> The sampling device for a tea making machine of the present invention is provided in a tea making machine, receives a part of tea leaves falling inside the tea making machine, and measures a predetermined property. In the mechanism described above, one or several protrusions are fixed to the fixing member of the tea making machine so that falling tea leaves collide above the sampling means inserted into the tea making machine. Therefore, the above problem is to be solved by this.

<Operation of the device> The tea leaves fall on the sampling means inserted inside the tea making machine and are taken out of the machine. When the tea leaves form a nodule, they collide with one or several protrusions arranged above the sampling means, are crushed finely, and are dropped on the sampling means after being slowed down, Taken out.

<Embodiment> First, reference numeral 1 is a sampling device, and 2 is a trough as a sampling means. The trough 2 has its starting end 2'inserted into the machine through an outlet 5 provided in a side plate 4 of the tea making machine 3, and supported by a plate spring 6 on an underframe 8 fixed by a supporting member 7. Drive springs 10, one end of which is fitted into the eccentric shaft 9, are attached to both sides of the rear end of the trough 2. Reference numeral 11 is a drive unit for rotating the eccentric shaft 9.
A drop hole 2 ″ is provided at the bottom end of the trough 2, and a measuring means for measuring the properties of the tea leaves and a transporting means to the measuring means are arranged below the falling holes 2 ″. It is returned to the cabin by the return means 13 inserted in. The measuring means and the returning means are not the gist of the present invention, and therefore their explanations are omitted. Reference numeral 14 is a breathable shatterproof cover attached to the trough 2. Reference numerals 15 and 15 'are protrusions, which are characteristic features of the present invention, and are attached to the side plate 4 which is an example of a fixing member above the starting end portion 2'of the trough 2. This specific shape is, for example, a round bar fitted with a fluororesin tube. Further, the projections 15 and 15 'are inclined by 6 ° with respect to the horizontal so as to descend as they move away from the side plate 4, and the projection 15' in the front is arranged at a higher position. In this embodiment, a rough kneading machine is used as the tea making machine 3, and 16 is a spindle, 17 is a kneading hand, 18 is a leaf dredge, and 19 is a hot air outlet.

The tea leaves introduced into the tea making machine 3 are subjected to a massage pressure by a massager 17 as the main shaft 16 rotates, are agitated by a leaf dredge 18, and are exposed to hot air blown out from a blower outlet 19. on the other hand,
In the sampling device, the eccentric shaft 9 is rotated by the operation of the drive unit 11, the drive spring 10 reciprocates as shown by arrow A, and the trough 2 vibrates as shown by arrow B. A part of the tea leaves agitated in the machine falls on the starting end portion 2'of the trough 2, is conveyed by the vibration of the trough 2 to reach the end, and drops downward from the dropping hole 2 ". The property is measured and returned by the returning means 13 to the cabin.

Tea leaves during the tea making process, especially tea leaves in the early stage of drying containing a large amount of water, tend to form nodules. If the nodules fall directly on the trough 2, not only the life of the sampling device 1 is shortened by the impact, but the nodules are As it is conveyed by the trough 2 as it is, it overflows in the middle, and the supply amount varies, which causes a measurement error. However, in the present invention, the nodule of tea leaves collides with the projections 15 and 15 ″ and is finely crushed, and the drop speed is slowed down and then drops onto the trough 2, so that the above-mentioned problem is solved. The number of 15 and the interval may be selected according to the state of the tea leaves processed by each tea making machine 3, but if the interval is too wide, there is a risk that the nodule will drop directly onto the trough 2 through the interval. If the width is too narrow, a bridge phenomenon (a state in which a bridge of tea leaves is bridged between the protrusions) may occur, so care must be taken.

In this embodiment, the friction coefficient is reduced by arranging the fluororesin tube on the outer circumference of the protrusion so that the tea leaves are not caught by the protrusion. Further, since a part of the hot air blown out from the blow-out port 19 blows out from the take-out port 5, a scattering prevention cover 14 is provided to prevent the tea leaves on the trough 2 from being blown off at that time. The sampling means of the present embodiment is the trough of the vibration conveyor as described above, but the point is that if the tea leaf can be taken out as a sample by being inserted into the tea making machine 3,
For example, various means such as a belt conveyor and a chute can be adopted. The sampling may be continuous or discontinuous. The shape of the protrusions may be any shape so that the tea leaves or tea leaves are not caught between the protrusions, but specifically, a shape elongated in any direction in plan view is desirable.

<Effect of the Invention> According to the sampling device for a tea making machine of the present invention, the nodule of the tea leaves collides with the protrusion and is finely crushed and then drops onto the sampling means, so that the sampling amount is stable and the measurement accuracy is improved. . Further, since the nodule does not drop directly onto the sampling means, it is possible to prevent the device from being damaged due to impact and to extend the life of the device.
