The measuring rod 21 is formed into a double cylinder structure with a cylindrical measuring rod 21a on the inlet side and an outlet-side cylindrical measuring rod 21b that is slidably fitted on the outer side of the measuring rod 21a, and expands and contracts. This makes it possible to change the weighing volume of coffee beans. Holding in the stretched state can be performed, for example, by tightening a fixing screw provided on the outer cylinder to the inner cylinder. In addition, by setting a scale or the like on the cylinder, the volume of the measuring rod 21 can be easily set.
[0020]
In addition, on the inlet 22 side of the weighing rod 21, a shutter housing body 26 that protrudes long downward to guide the vertical movement of the inlet-side shutter 24 and accommodates the shutter 24 when the inlet is opened is fixed. On the outlet 23 side, a shutter housing body 27 is provided which protrudes long upward and guides the vertical movement of the outlet side shutter 25 and accommodates the outlet side shutter 25 when the outlet side is opened. Both the storage bodies 26 and 27 can be formed by superimposing two plate bodies each having a shutter storage space inside and fixing them with screws. When formed in this way, it is easy to disassemble and convenient for cleaning.
[0021]
The link mechanism L that operates the entrance-side shutter 24 is provided in parallel with the first link 29 that is pivotally supported by the upper end 26a of the entrance-side shutter housing 26 so as to be pivotable in the vertical direction. The first link 29 is connected to the distal end of the first link 29 and the base end of the second link 31 is pivotally attached to the bracket 24a of the entrance shutter 24 by a pin 24b. In a normal state (initial state) in which the first link 29 is not rotated, a pin 31a fixed to the tip of the second link 31 is slidably inserted into the long hole 29a. Is in a closed state (see FIG. 3).
[0022]
Then, the operation lever 53 attached to the measuring instrument housing 50 is concavo-convexly fitted to the support shaft 28 of the first link 29, and the first link 29 is rotated downward (rotated counterclockwise in the drawing). The entrance-side shutter 24 is opened by sliding downward. Further, when closing, the operation lever 53 is turned upward (rightward in the drawing) as the return direction.
[0023]
On the other hand, the exit side shutter 25 is provided with a rotation shaft 33 parallel to the support shaft 28 of the first link 29 on a bracket 32 provided on the upper side of the entrance side shutter storage body 26. A locking lever 34 extending in the direction of the center of the upper edge of the first link 29 is fixed in parallel with the first link 29, and a pin 34a perpendicular to the locking lever 34 is projected from the tip of the locking lever 34. Is provided at the upper edge of the first link 29 and is locked to a locking piece 29b which is long in the longitudinal direction and has an opening at the tip end side of the link. In addition, a support bar 36 extending to the upper part of the outlet side shutter 25 in parallel with the first link 29 is fixed to the other end of the rotating shaft 33, and the tip of the support bar 36 is provided on the upper part of the outlet side shutter 25. The bracket 25a is attached by being gently engaged with the insertion hole 25b formed in the bracket 25a.
Then, the pin 34a at the tip of the locking lever 34 is slid in the left direction by the operation of the first link 29 in the downward direction (left rotation in the drawing), and the first link 29 is locked in the middle of the rotation. The pin 34a is released from the opening 29c at the end of 29b to unlock the locking piece 29b, and the outlet side shutter 25 is closed while the support bar 36 is tilted by its own weight (see FIG. 4). ).
[0024]
Note that the support rod 36 is formed to be flexible to some extent by using an elastic member 36a as a part so that the operation of the exit side shutter 25 can be performed smoothly. Further, a spring 37 between the first link 29 and the upper portion 26a of the entrance-side shutter housing 26 is returned to the normal position before the first link 29 starts measuring when the rotation operation by the operation lever 53 is released. Similarly, between the upper portion 26a of the entrance-side shutter housing 26 and the bracket 24a of the entrance-side shutter 24, when the rotation operation by the operation lever 53 is released, the entrance-side shutter 24 and the second link are connected. A spring 38 is stretched to lift the base end of 31 and return to the normal position before starting the measurement.
In addition, the upper end storage portion of the entrance-side shutter 24 that is closed so as to push up from below has a space S serving as a certain escape space so that coffee beans are not sandwiched between the upper end of the closed shutter and the weighing basket. Provided. Thereby, bean cracking due to pinching can be prevented more reliably.
[0025]
Next, the operation of the operation lever 53 configured as described above, the operation of the link mechanism L and the shutters 24 and 25, and the movement state of the coffee beans M will be described.
First, FIG. 4 shows an initial state in which the entrance-side shutter 24 is closed and the exit-side shutter 25 is opened, and the operation lever 53 is raised (position A in FIG. 4). In this state, the coffee beans M enter the inlet 22 of the weighing basket 21 from the bottom of the container set on the upper side and stay in front of the entrance-side shutter 24.
[0026]
When the operation lever 53 is lowered from the A position to the left and moved to the B position in FIG. 5, the first link 29 also rotates counterclockwise, and the tip of the second link 31 slightly moves to the lower left due to the engagement with the pin 31a of the second link. However, the pin 31 moves in the long hole 29a at the tip of the first link to the left end of the long hole. At the same time, the pin 34a at the tip of the locking lever 34 also slides to the left, and the pin 34a is removed from the opening 29c at the end of the locking piece 29b. Then, the exit-side shutter 25 is dropped and closed while the support rod 36 is tilted by its own weight (see FIG. 5). At this time, since the entrance-side shutter 24 is still closed, the coffee beans M still remain in front of the entrance-side shutter 24.
[0027]
When the operation lever 53 is further lowered to the left and moved to the position C in FIG. 6 from this state, the engagement between the first link 29 and the outlet side shutter 25 has already been released, so that only the inlet side shutter 24 is operated. . That is, the first link 29 is further lowered to the lower left by the operation of the operation lever 53, the second link pin 31a is pushed down at the end of the long hole 29a of the first link, and the entire second link 31 is lowered. The entrance side shutter 24 attached to the end is pushed down to be fully opened.
At this time, the coffee beans M stored in the upper part flow into the measuring basket 21, are blocked by the closed outlet side shutter 25, and are filled in the measuring basket 21.
[0028]
Then, when the operating lever 53 is returned to the position B in FIG. 7 from this state, the entrance side shutter 24 is also helped by the contraction force of the spring 38, and moves upward while rubbing the coffee beans M (FIG. 7). ). At this time, the effect of the space S provided in the closed portion of the entrance-side shutter 24 and the entrance-side shutter 24 closed by the operation of pushing up from the bottom allows the coffee beans to be entered without being sandwiched between the inside of the measuring basket 21 and the shutter 24. The side shutter 24 can be fully closed.
[0029]
When the operation lever 53 is returned to the A position, which is the fixed position shown in FIG. 8, with the entrance side shutter 24 fully closed, the pin 34a comes into contact with the upper edge of the first link 29 and is engaged. The stop lever 34 is moved to the right, the support bar 36 that operates integrally with the stop lever 34 is lifted, and the outlet side shutter 25 suspended at the tip thereof is pulled up to be fully opened. As a result, a predetermined amount of coffee beans weighed by the weighing basket 21 is discharged to the outside from the outlet 23, and sold in a storage bag or the like prepared underneath.
[0030]
By the way, the measuring rod 21 has a double structure in which two cylindrical bodies 21a and 21b having different diameters are slidably fitted, so that the length of the rubbing portion is changed as shown in FIG. Thus, the amount can be adjusted freely. In addition, since the support rod 36 of the exit side shutter is formed flexibly, even if the support angle by the support rod 36 is changed by adjusting the length, it operates without any problem.
[0031]
【The invention's effect】
As described above, according to the manual metering device for coffee beans and the like of the present invention, the inlet side shutter and the outlet side shutter are opened and closed with a time lag through the link mechanism, and the coffee beans stored in the container, Accurate weighing can be done by the capacity of the weighing bowl. In particular, after storing coffee beans in a cylindrical measuring bowl, when closing the shutter on the entrance side, the shutter is closed so as to push up from the bottom, so that the beans stay at the tip during the shutter closing operation. There is no such thing as falling and coffee beans are not pinched and crushed by the closed shutter.
[0032]
Further, in the manual quantitative metering device of the present invention, if a certain space is provided in the storage portion of the entrance-side shutter that is closed so as to push up from the bottom, this also becomes an escape space for coffee beans and the like. It is possible to reliably prevent bean cracking due to pinching and always weigh good quality coffee beans without cracking.
In addition, the above-mentioned quantitative measuring device for coffee beans, etc., can be expanded and contracted by forming a cylindrical measuring basket in a double structure that can be slid by overlapping from both left and right sides, so that the measuring volume of coffee beans can be changed. It can easily handle the sales of coffee beans with different capacities.
