Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a blending weighing device in which a weighing hopper and a storage hopper are mounted on a cart.

2. Description of the Related Art This type of blending measuring device has a trolley (as shown in FIG. 5).
1) is equipped with a weighing hopper (2) and a storage hopper (3), and the trolley (1) is configured so that it can move between the station consoles P and P4. In this case, park the trolley (1) at station P, and start charging raw material A from the hollow / When the predetermined value is reached, the cutting from the hopper (4) is completed, the raw material A in the weighing hopper (2) is discharged in its entirety to the storage hopper (3), and the cart (1) is moved to station P2.

At station P2, a predetermined amount of raw material B is weighed using the weighing hopper (2), and the entire amount of raw material B is discharged into the reservoir collar (3) into which raw material A has already been placed, and then transferred to station P, where it is transferred to the trolley (1). ) to move. Also, station controller P
However, the raw material C is weighed and the entire amount is discharged into the storage hopper (3). When the cart (1) arrives at station P4, the gate (7) of the storage hopper (3) is opened to discharge the entire amount of raw materials (A+B+C).

In this way, the weighing hopper (2) is mounted on the trolley (1) and the hopper (4) (5) (ti
), the hopper (4) (5
) (6) It is not necessary to install a weighing device for measuring the cut-out amount, and if the storage hopper (3) is mounted on the trolley (1), the trolley (1) can be moved to the discharge position every time one raw material is weighed. Since there is no need to move it to station P4, it is useful for shortening the dispensing and measuring time.

However, for example, if more than the required amount is put into the weighing hopper (2) during the measurement of raw material B, the worker must use a long ladle from a high place (8) to remove the excess amount in the weighing hopper (2). Raw material Btl-must be fried.

Problems to be Solved by the Invention As described above, in the conventional blending weighing device, the weighing hopper (
2) If more than the necessary amount of raw material is put into the process, move it to a high place (8
) has the disadvantage of being forced to perform dangerous work.

SUMMARY OF THE INVENTION An object of the present invention is to provide a blending weighing device that is safe and has good operability without requiring dangerous work from a height even when raw materials are put into a weighing hopper.

Means for Solving the Problems The blending weighing device of the present invention has a weighing hopper and a blending moistening hopper for receiving the raw materials discharged from the weighing hopper mounted on a trolley and can be moved between each raw material discharging position. In addition, an auxiliary storage hopper separate from the blending storage hopper is provided on the trolley, and an auxiliary gate for discharging raw materials only to the auxiliary storage hopper is provided in the weighing hopper, separate from a main gate for discharging raw materials to the blending storage hopper. It is characterized by having a gate.

Function: With this configuration, surplus raw materials input into the weighing hopper can be discharged from the auxiliary gate to the auxiliary reservoir hopper, and the required amount of raw materials can be discharged from the main gate to the blending reservoir hopper. It is safe as it does not require the work of removing the paper from a certain place, and it is also easy to operate by simply opening and closing the auxiliary gate.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4.

(A) is mounted on the trolley (1) with nine weighing hoppers, and the load is set! It is attached to the support frame (9) on the truck (1) side via a screw (not shown). (3) is the weighing hopper (
2) A gate plate (2) is attached that is slid and driven in the vertical direction by a ring device @. α is an auxiliary reservoir hopper attached to the blending reservoir hopper (C), and the discharge port (G) is the discharge port (B) of the blending reservoir hopper (A).
A gate (G) is located above the cylinder device and is opened and closed by a drive unit (not shown) separate from the cylinder device. ) is opened at a position near. In addition, the weighing hopper (,
An auxiliary discharge port (α) is provided on the tank slope (g) of () to discharge the raw material only to the receiving port αη of the auxiliary reservoir hopper σ. is installed.

Furthermore, as shown in FIGS. 3 and 4, a chute extending from the vicinity of the receiving port eυ to the vicinity of the auxiliary discharge port is attached inside the weighing hopper hook. eA(to) is the supporting frame of Nyuto@.

With this configuration, even if too much raw material B enters the weighing hopper A (2) at station P2 in FIG. 5, the surplus can be removed from the weighing hopper (0) by simply opening the auxiliary gate.

In other words, when the auxiliary gate is opened, the raw material B in the weighing hopper (a) is discharged from the auxiliary discharge port to the auxiliary reservoir hopper α fathom, and the raw material A has already been input from the auxiliary discharge port 4. It is not discharged to the mixing hopper (go). Then, when the raw material B in the weighing hopper (i) reaches the appropriate amount, the auxiliary gate (e) is closed, and after that, the raw material B in the weighing hopper (') is made into the required amount, and the main gate α0 is opened and the main gate α0 is opened for blending. Discharge the entire amount of raw material B to the storage hopper (k). In addition, raw material B in the auxiliary storage hopper (B) is at station P.
, before starting to input the raw material C, the gate α is opened at a station at a predetermined position and the entire amount is discharged, and the discharged raw material B is returned to the hopper (5) at an appropriate time.

The raw material C is weighed in the same manner, and the gate plate □□□ of the blending reservoir hopper (i) is opened at station P4, and the raw material (A+B+C) is completely discharged into the receiving port.

As mentioned above, since the sheet (E) is provided in the weighing hopper (A), even if only a small amount is to be weighed compared to the weight of the weighing hopper ('), a small amount of raw material B, Since it is guided to the auxiliary discharge opening side by the chute, it is possible to prevent a situation where it accumulates only above the main gate αO and does not bend to the auxiliary discharge port side.
Even if there is only a small amount of raw material B, the amount of raw material in the weighing hopper can be adjusted by opening the auxiliary gate H. (B2
) represents the raw material when the amount weighed in the weighing hopper (S') is large, and in this case, it also goes around the back of the chute. In the above embodiment, the shade rock has an L-shaped horizontal cross section, but it can also be a cylindrical chute.

As described in the detailed description of the invention, the blending weighing device of the present invention is capable of loading surplus raw materials and ingredients in a weighing hopper mounted on a trolley onto the trolley via an auxiliary gate provided in the weighing hopper separately from a main gate. Since the material can be discharged to the auxiliary hopper, there is no need to climb over the excess material in the weighing hopper from a high place, unlike conventional methods, and all you have to do is open and close the auxiliary gate, making it safer and more efficient. It has good operability.
