Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a device that rotates a substrate by a rotational drive mechanism, is equipped with an automatic distribution feeder, distributes a required amount of powder into predetermined divided masses, and packages the same. The present invention relates to a powder dispensing machine with packaging machine equipped with an electronic control device that automatically controls each of the above operations.

Conventionally, in a powder dispensing machine that divides and packages powders, a division mass provided in an annular shape at the bottom of a powder feeder is rotated left and right to ecim, and the dispensing and packaging operations are performed by repeatedly causing the powder to flow little by little from the powder feeder. In addition, as a countermeasure against powder adhesion inside the feeder or instability in the flow rate from the feeder, there are distribution machines that have a vibrating device added to the feeder itself to ensure accurate flow. , all of which are already publicly known.

However, in order to determine the amount of powder that flows out, with conventional equipment, the distribution work is carried out while manually adjusting the gate, etc., which often requires a single operator's intuition11c@, resulting in operational problems. A skilled tatami worker outside.

In these automatic distribution machines, there is a lot of waiting time between the distribution work in the previous process and the start of the next distribution process. Because of this, there has long been a demand for a device that can operate at high speed and process accurately.

The present invention has been made to deal with the above situation.

By using a simple mechanism and making full use of electronic equipment, the waiting time for each task can be reduced.

While accurately and quickly distributing the powder and verbally packaging it,
The object of the present invention is to provide a powder distributing machine with a packaging machine that enables the next distributing operation to be started.

Embodiments of the present invention will be described in detail below based on the drawings. 1II is a front cross-sectional view showing the entire device;
3 is a front sectional view of an automatic distribution feeder mechanism that automatically distributes powder, and FIG. 4 is a control block diagram for controlling the operation of the apparatus. First, the shaft center 2 of the machine base L is tightened and fixed with a collar (first and second) 4HC, and the shaft,! ! An annular divided mass 3 rotatably arranged around #2, and a bearing 31 that is rotatable near the inner circumferential surface of the wrinkled annular divided mass 3 and concentrically with the axis 2 of the machine base l. There is a substrate 4 provided, and a rotary drive machine 115 for driving the substrate 4v is provided between the substrate 4 and the annular divided mass 3. Further, the annular divided masses 3 are arranged in a predetermined number (II
In the example shown, 84 units) are arranged, and a bottom IIM closing mechanism 6 is provided on the bottom of each of them, making it possible to open and close the bottom cover.

The rotary drive mechanism 5 is screwed onto the base plate 4 by a fixed plate 20, and includes a rotary motor set 21, a pinion connected to the cough suppressor 12 shaft, and an inner ring provided on the inner peripheral surface of the annular divided mass 3. The rotation of the rotating motor 12 rotates the binion ]0, which is meshed with the inner gear ].

Furthermore, a photoelectric, magnetic, or mechanical rotational position detection sensor 13 is mounted on one end of the substrate 4 to detect the inner gear.
It is installed close to 1.

For example, each of the annular divided masses 3 and each tooth of the inner gear 11 are configured in a positional relationship corresponding to each other.

Further, there is an automatic distribution feeder mechanism 7 on the substrate 4, and one end of the automatic distribution feeder mechanism 7 has an outlet 1 for the VCg agent.
4 and a rotation fulcrum 15 are provided.

It has a mixing tank 16 rotatably installed around a skeleton rotation fulcrum 15, a tilting motor 17 for rotating the mixing tank 16, a drive transmission mechanism 18 including a sprocket ρ, 23, and chains. A supply gutter I suspended from the tip of the outlet 14 and a vibration mechanism 19 provided in contact with the lower part of the mixing tank 16 are provided. Then, the mixing tank 16 moves in the direction of the arrow (see Figure 3).
Powder detection sensors are provided to detect contact with powder when K is tilted, and the angle of inclination is automatically controlled as will be described later to ensure uniform distribution of powder. on the other hand,
A packaging mechanism 8 is arranged below the annular dividing mass 3, and the packaging mechanism 8 is a well-known 5itI! - Packaging as a packaging mechanism! One bag is mainly composed of a vertical division line welding mechanism A, a stamping mechanism N, and an enclosing line welding mechanism A. In this way, a wrapping completion signal is sent to the control section every time one package is completed.

The operation and usage of the distribution machine with packaging machine having the above configuration will be explained with reference to FIGS. When any position is specified among the left and right end cell positions of the range of divided cells to be distributed, the specified position and the current position of the feeder unit suspended at the tip of the mixing tank outlet 14 are determined. Is the difference between the memory section and the control section column via 9V? ' is calculated, and a rotation direction specifying signal for the direction closer to either the forward or reverse direction is given, and the motor drive circuit 32 rotates the rotation motor to reach the target position.

Next, the board 4 is divided to distribute the powder! The allocation is started by repeating the back-and-forth operation according to the number of slots. Here, the initial position of the annular divided mass 3 is the inner gear 1. Measures are taken to change the output of the rotational position detection sensor 13 at a specific position (such as giving a cut to the gear itself), and the scissors position is detected by the rotational position detection sensor 13. For example, in Figure 2, the feeder section is 43 meters counting from the first initial position.
Assuming that it is stopped at Kome and repeats the back and forth movement while dividing the powder into 7 squares from 43 to 49, 439
The rotation position detection sensor 13 detects the movement of the 6th square from the first square, and immediately after passing the 48th square corresponding to the 6th square, a brake signal or rotation %-ta 1 is sent.
2 and moves to exactly the 49Ith square and stops, and then starts driving in the opposite direction. At this time, it is desirable to perform control such that stopping and starting at the left and right turning points are performed smoothly so that the powder is evenly distributed to each square. In addition, the powder is supplied to the divided masses by rotating the mixing tank 16 by the automatic distribution feeder mechanism 7 and dropping the powder, and the pre-measured powder of a single type or multiple types is fed into the mixing tank 16°. The powder in the mixing tank 16 is vibrated to mix it completely, prevent it from adhering to the inner wall of the mixing tank, and rotate the tilting motor 17. and the mixing tank 16 via the drive transmission mechanism 18.
Tilt. Before the powder reaches the outlet 14, it first comes into contact with the powder detection sensor 2511C@, and a signal is emitted from the sensor 5, which sends it to the control section.

At this time, the vibration mechanism 1 provided in the lower part of the mixing tank 16 & C1l
9 rotates together with the mixing tank 16 when the mixing tank 16 moves.

As described above, the amount of powder falling into the divided squares is controlled to be constant by the tilting of the mixing tank 16 and the output of the powder detection sensor 5.

In this way, when the mixing tank 16 rotates on its own axis and rotates to a position of approximately 90 degrees in terms of one rotation angle, there is no remaining amount of powder, and the powder detection sensor 25 confirms that the distribution has been completed, and the tilting motor 17v is reversed to rotate the mixing tank 16. Restore to original position. Next is the packaging worker 1! In this case, the annular divided mass 3 is rotated by a divided mass driving device (not shown), waits below the annular divided mass 30, and stops directly above the packaging mechanism 8 having the powder receiving port 39. do. At this time, the amount of rotation of the annular divided mass 30 is constantly detected by a sensor (not shown) as to where the powder receiving port 39 is, for example, relative to the initial position of the divided mass that has completed distribution or the inner gear 1.

The information is sent to the control unit 28, and the positional difference between the mass position containing the powder and the powder receiving port 39 is calculated in the same manner as described above, and the annular divided mass 3 is rotated by the divided mass driving device (not shown). Then, the bottom lid of the mass containing the powder is opened by the bottom lid opening/closing mechanism 6, and packaging is started. thus.

Each time the packaging mechanism 8 completes one square, a signal is emitted from the packaging mechanism 8, and each time the annular divided square 3 wraps one square.
Rotate by the pitch and the bottom cover of the next square will be opened.

Do as above! The next packaging operation is carried out, and during this operation, new powder is added to the mixing tank 16, and the substrate 4 is moved by the rotary drive machine $5 in the same way as above based on the command from the control section. To move to the position of an empty divided square.

The feeder at the tip of the mixing tank 16 also moves together to start distributing the powder anew. The reason why the packaging work and the distribution work can be performed at the same time as described above is because the relative positional relationship between the annular divided mass 3 and the substrate 4 is determined by the fifth bin 10 of the rotational drive mechanism 5 and the inner gear Ilk. .

The operations of each of the above mechanisms are all driven and controlled by commands from the control section of the input control device 90, or a group of manual switches are installed to start operations, set packaging, etc. Of course, it is possible to do the following.

Next, to briefly explain the control mechanism block diagram shown in FIG. 4, the signals inputted through the input control device 90 and the input device γ are temporarily stored in the memory section 29 of the control section 4, and then transmitted through the interface. The rotation motor 12 is driven by the motor drive circuit 32 and the inner gear 11. The board 4 rotates back and forth through the gear device of the binion 10.Is this movement due to the rotational position detection sensor? -13K is fed back to the control section. On the other hand, after 1 jl of powder is stored in the mixing tank 16, control! A drive command is sent from +28 to the automatic distribution feeder mechanism 7, and the vibrator #119 starts vibrating through the t drive circuit 34v, and the tilting motor 17 is rotated by the motor drive circuit 33, and the vibration is transmitted through the drive transmission mechanism 18. Then, the mixing tank 16 starts rotating. In this case as well, the output from the powder detection center t-25 is fed back to the control section Z. Then, a distribution completion signal from the powder detection sensor 5 is detected and the mixing tank 161' is restored to its original position. At the same time, the rotation of the rotating motor 120 is stopped, and the mass to which the powder has been distributed is rotated by the divided mass drive device 35 to the powder receiving port 39 of the packaging mechanism 8, and the powder is dropped from the rear bottom opening/closing mechanism 6)C. The packaging is completed and one or more control signals are sequentially commanded from the control $28.

performed automatically. Also, in the above theory @, the automatic distribution of powders has been explained, and the object to be distributed is not only powders but also tablets, and the motor 17 for one rotation amount recognition and tilting is as follows. It is possible to use pulse motors, servo motors or regular motors.

As described in detail above, the present invention includes an automatic distribution feeder on a rotatably driven substrate, a packaging mechanism for packaging the powder, and a control device for automatically controlling these. It is possible to simultaneously package the powders that have been distributed and to make new distributions to the vacant divided spaces, and the flow rate of the powders can be automatically set, and all operations can be automatically controlled. less time
