Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a powder raw material supply device which is capable of adjusting and supplying the powder raw material into the powder during compression molding of powder raw materials such as tiles and bricks. It is related to.

Conventionally, such a powder raw material supply device has a hopper (b) placed above the powder supply position (a) as shown in Fig. 1, and the powder bowl (11) is located in the hopper (1)). When the hopper (b) is retracted to a lower position, the outlet (C) of the hopper (b) is opened to replenish powder raw material into the powder container (a), but the outlet (C) of the hopper (b) is (1) is powder first (a
) passes below the hopper (b).
) is located above the top surface of the hopper (b).
The powder raw material replenished into the powder mold (fa) is always fully supercharged, so that the powder raw material is kept in the atmosphere during the movement of the powder mold (i) and the application of the by-play scene on the lower mold. It is also possible to prevent supercharging of powder j and π into powder (a) by setting it together with scattering on the formwork and contaminating the working area. In this case, it is practically impossible to completely synchronize the replenishment amount with the amount L1 due to molding of the powder raw material, so repeating the replenishment operation will eventually result in a supercharging state or a shortage of raw materials, as described above. In view of these drawbacks, the present invention disposes a hopper above the first catching position of the flour mass, which is controlled to reciprocate horizontally on the formwork, and the hopper An embodiment of the present invention will be described below based on the drawings, in which the above-mentioned drawbacks are solved by supporting the powder container so that it can rise and fall freely from the upper part of the outside to a predetermined height position inside. ) is a supply device for powder raw materials (goods),
It is mounted on the formwork (8) of the press machine (2), and the formwork (8)
) are disposed on both sides of the rails (4) (4)', and the rails (4) (4) I are provided with a powder first to fill the powder raw material (goods) into the lower mold (51). 16) is horizontally movable via v (71), and the wax powder (6) is placed in the powder cylinder (8) at the upper and rear raw material replenishment positions of the lower mold (5). (9) to control the reciprocating movement between the two.

Also, at the raw material replenishment position (9), both (1
A kite rod (131 (18-bit At the same time, the guide rod aal u8+' is placed at a position facing above the raw material replenishment position (9).
The upper 1c of the hopper set frame 1121 has a cylinder (10) erected thereon, and the rod (+7) of the cylinder (lG) is projected from the upper part of the hopper a→. The cylinder α6) is used to lift the hopper until the powder (6
) is controlled to move up and down so that it moves from the upper part of the outside to a predetermined height position inside. The intrusion dimension of the hopper (06) into the flour mass (6) can be freely set by adjusting the stroke of the cylinder (06) using a limit switch, a stopper, etc.

@) is the hopper opening/closing mechanism, and the hopper's outlet is 0.
An arm (211121) with its upper end pivotally supported on both sides of the hopper 041 is provided on the lower surface of the casting surface to allow the shutter 1221 to be opened and closed freely, and a mounting plate (
The cylinder is pivotally supported via a rod (251), and one end of the cylinder (251) is connected to the arm
Attach the connecting rod (2Ql 叡1) to the other end,
The operation of this cylinder controls the opening and closing of the IF filter.

Next, to explain the operation of the powder raw material supply device according to the present invention, when the powder bowl (0) retreats and returns to the raw material supply position (9) as shown in FIG. The hopper 〇 (trans) waiting at the cylinder (1G
) is operated, the guide rod Q8) descends and enters the hopper to a predetermined height position, and then the cylinder of the hover opening/closing mechanism operates and connects the connecting rod.
As the shutter moves backward via the arm (21), the discharge port (increase) is opened, and υ is replenished from the hopper 0 to the powder raw material in the powder first (0), and the powder raw material When υ is replenished until it blocks the discharge port 0 of the hopper hook, the flow of υ from the hopper 0 to the powder raw material is naturally prevented, and after that, the cylinder operates again and the discharge port 0 is blocked.
0) is closed by the shifter 122), and the cylinder α0) is operated to return the hopper circle to the outside of (0) for 1 minute.
) is replenished with powder raw material (Ml) in an amount equivalent to the amount consumed by molding, and then powder (6) is supplied under the press (2) by the operation of the powder cylinder (81). The powder raw material σ541 is transferred horizontally onto the mold (6) and filled into the lower mold (5), and then compressed into the press machine (2). The powder raw material ffv'll in an amount equivalent to the amount consumed by retreating back to IFt (9) is replenished again, and by repeating the above operation, the powder used for compression molding in the press machine (2) is sequentially and continuously. The body raw material (N1) is supplied.

In short, the present invention arranges and faces the formwork (in the hopper above the raw material replenishment position IFt (n) of powder (6), which is controlled to reciprocate horizontally on 81), and the hopper (141)
Since the hopper a (6) is supported so that it can rise and fall freely from the upper part of the outside to a predetermined height position inside the hopper a (1), when replenishing the powder raw material M into the powder receptacle (6), Powder raw materials (goods) can be replenished while 19) is placed in the flour bowl (6), so the flour bowl (6) will not be full and can be refilled with plenty of room. This prevents the powder raw material (goods) from spilling onto the formwork (8) during the transfer of the powder (0) and the pie-bracing scene on the lower mold (5), thereby preventing contamination of the working environment and raw materials. It is possible to prevent wasteful consumption of the hopper, and the I cylinder at the lowering entry position of the hopper is used to transfer the powder to the powder raw material in (0).The J claw can be arbitrarily set according to the consumption amount. Quantity) k, and in any case, the amount replenished is always constant until the powder raw material ｽυ closes the discharge port (19) of hopper 04], so the success rate (y
Its practical effects are extremely great, such as being able to completely synchronize the consumption and replenishment amounts of the powder raw material □□□D.
