Description

  The present invention relates to a metering and filling device that measures tea leaves (generally referred to as strawberry tea) that have been made into tea for use as a matcha tea material, and fills it into a large sea bag.

  Processed tea leaves (sencha, green tea, etc.) are generally filled in a special bag called a large sea bag and shipped after inspection. In order to pack tea leaves that have been processed into tea into a large sea bag, there has been proposed an apparatus (patent document 1) that weighs before placing and puts it into the large sea bag while applying vibration. In addition, a device (Patent Document 2) has been proposed that measures the power of a vibration generator and measures the amount to be charged while applying vibration to the tea leaves being charged.

  The large sea bag 1 is a bag filled with tea, and the volume of the large sea bag for tea is approximately twice the volume of the large sea bag for general sencha. Although the capacity | capacitance of the large sea bag 1 of this embodiment is a 20 kg type, there exists a 30 kg type etc. in addition to this.

  The inspection table 40 serves as a scaffold during the inspection of the automatic weighing and filling apparatus S. As shown in FIG. 2, an inspection passage 41 is provided from the pool portion 10 to the filling portion 30. Further, as shown in FIG. 4, a ladder 42 is provided for ascending from the floor surface G to the inspection passage 41.

  The control unit 50 is used for the operation of the automatic metering and filling device S. The control unit 50 measures the tea tea by the metering unit 20, transports the tea tea by the first transport unit 60 and the second transport unit 80, and the large sea bag to the filling unit 30. Each holding state of 1 is controlled. The control unit 50 can be switched from automatic operation to manual operation. As shown in FIG. 6, the power switch 51, the manual switch unit 52, the temporary stop button 53, the display panel unit 54, the power lamp 55, the measurement completion lamp 56, A discharge completion lamp 57 is provided. The manual switch 52 includes a screw drive switch 52A, a first trough conveyor drive switch 52B, a hopper vibration switch 52C, a second trough conveyor drive switch 52D, an open / close gate drive switch 52E, a bag press switch 52F, a bag vibration switch 52G, and compression. A cylinder drive switch 52H is provided. The display panel unit 54 displays an automatic operation start button for starting automatic operation.

  Next, the operation and use method of the automatic weighing and filling apparatus S configured as described above will be described.

  First, an operator opens the large sea bag 1 and sets it on the support frame 31 of the filling unit 30. Next, the operator turns on the power switch 51 of the control unit 50 and presses the automatic operation start button of the display panel unit 54.

  When the automatic operation start button is pressed, each press holding part 32 of the filling part 30 is operated, and the large sea bag 1 set in the open state on the support frame 31 is pressed and held (clamped) by each press holding plate 32b at the tip. . In parallel, the drive motor 66c of the first transport unit 60 is activated to start (or resume) the front and rear vibration of the first trough conveyor 62, and is discharged onto the first trough conveyor 62 from the discharge port of the pool unit 10. Green tea is conveyed toward the measuring unit 20.

  In the weighing unit 20, the tea tea discharged into the weighing hopper (the upper tank unit 22 and the lower hopper unit 24) from the tip of the first trough conveyor 62 passes through the weighing hopper and is discharged onto the second trough conveyor 82, It is weighed by the platform scale 28. When the tea reaches a predetermined amount (20 kg), the weighing completion lamp 56 of the control unit 50 is turned on, and the longitudinal vibration of the first trough conveyor 62 is stopped. Also, the drive motor 86c is activated in response to a signal from the platform scale 28, starts (or restarts) the longitudinal vibration of the second trough conveyor 82, and the opening / closing gate 88 at the tip of the second trough conveyor 82 is opened. As a result, the tea is discharged from the tip of the second trough conveyor 82 into the inside of the large sea bag 1 set in the filling portion 30 in an open state.

  In the filling unit 30, the compression cylinder 36 is intermittently driven to intermittently move the compression shaft 36d up and down in accordance with the discharge operation of the tea brown into the large sea bag 1. As a result, as shown in FIG. 7A, the black tea T discharged into the large sea bag 1 is intermittently compressed by the vertical movement of the push plate 34 provided at the tip of the compression shaft 36d. Since the opening is provided in the push plate 34, the drop operation of the tea brown T is not hindered when the push plate 34 is pulled up as shown in FIG. When the entire amount (20 kg) of tea is discharged, the discharge completion lamp 57 is turned on, and the compression operation is completed simultaneously with the completion of the discharge of tea to the large sea bag 1. At the same time, the open / close gate 88 at the tip of the second trough conveyor 82 is closed, and the longitudinal vibration of the second trough conveyor 82 is stopped. Next, the rod 32 a of each pressing and holding portion 32 is reduced, and each pressing and holding plate 32 b at the tip is separated from the large sea bag 1.

  The operator takes out the large sea bag 1 filled with tea tea from the filling unit 30, sets a new large sea bag 1 in the filling unit 30, and presses the automatic operation start button of the display panel unit 54 of the control unit 50 again. The above steps can be resumed.

  In addition, although the conveyance of the tea to the pool part 10 is performed until a fixed amount is stored separately from the operation of stopping the operation of the automatic metering filling device S and the operation restarting, the operation of the automatic metering filling device S is performed. You may make it interlock | cooperate with each operation | movement of a stop and driving | operation restart.

  According to the automatic weighing and filling apparatus of the present invention, the following effects can be obtained.

  By simply setting the large sea bag 1 in the filling unit 30 and pressing the automatic operation start button of the control unit 50, a series of operations from weighing tea tea stored in the pool unit 10 to filling is automatically performed. The operator only needs to set the large sea bag 1 in the filling unit 30 and can save labor and labor.

  By the intermittent compression operation of the push plate 34 that moves up and down by the operation of the compression cylinder 36, the tea tea discharged into the large sea bag 1 can be efficiently filled while being lightly compressed. Since the tea is used as a matcha tea material, it can be crushed by the compression operation of the push plate 34. Rather, it is crushed so that the filling efficiency of the tea is increased, and the volume of the large sea bag 1 can be obtained without creating a gap from the bottom. Can be reliably filled.

  Since the screw transport unit 70 is provided, the transport amount can be finely adjusted when transporting tea to the measuring unit 20. For example, 90 to 95% of the predetermined amount is conveyed by the vibration type first trough conveyor 62, and the remaining 5 to 10% is measured by using the screw conveying unit 70, so that nearly 100% of the predetermined amount is measured. It can be conveyed to the part 20 and thus to the filling part 30.

  Thus, according to the automatic metering and filling device for tea tea of the present invention, it was possible to provide a metering and filling device that can automatically perform operations from the measurement of tea tea to the filling of large sea bags.

  In the above embodiment, the automatic weighing and filling apparatus for tea is described. However, the apparatus is not limited to tea and can also be applied as an automatic weighing and filling apparatus for tea making.

  INDUSTRIAL APPLICABILITY The present invention can be used as an automatic measuring and filling device for measuring stored tea tea and filling it into a large sea bag.
