Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for filling a bag (made of plastic, a waterproof film such as metal foil paper, a sheet, or a sheet) housed in an exterior body such as a paper box.

This type of conventional device requires the following two separate steps to fill the bag.The first step is to remove the cap from the outlet, and the second step is to
The process involves filling the bag with liquid from the discharge port with the cap removed, and the process does not proceed to the second process unless the first process is completed, so the filling operation takes a long time. Therefore, the purpose of the present invention is to provide a filling device that eliminates such drawbacks.The filling device according to the present invention includes a discharge port holder that freely holds the discharge port of the bag; It includes a cap removal part for removing a cap attached to the discharge port, and a filling head that engages with the discharge port to fill the liquid, the discharge port holder holds the discharge port, and the filling head When starting to approach the outlet, the outlet holder holds the outlet and the cap removal part moves away from the direction of movement of the filling head while holding the cap, thereby causing the outlet to move closer to the outlet. The removal of the cap removal portion to remove the cap from the outlet results in the subsequent approach and engagement of the filling head with the outlet.The invention will now be explained in more detail with reference to the illustrated embodiment.

The container filling device 10 shown in FIGS. 1 to 4 is suitable for filling bags made of glasstics or metal foil paper 8 and these bags have a discharge opening (8) which is sealed by a cap. The filling device 10 has a filling head 12 and a discharge port holder 13.
The discharge port holder 13 fixes the discharge port 13, and the cap of the discharge port is removed by the cap removal portion 14, and the filling head is moved to the discharge port. The cap removal portion 14 engages with the bag to fill the liquid into the bag.Furthermore, the cap removal portion 14 attaches the cap to the discharge port after filling the bag.

The filling head 12 and the character f removal part 14 move along the main frame 11. As shown, the cap removal section 14
The sliding part 1 is slidably attached to the cylinder 16.
It is fixed at 5. The cylinder 16 is fixed to the main frame 11, and the piston 17 of the cylinder 16 is connected to the sliding part 15 via a pin 18. Pin 18 is cylinder 16
When the piston 17 moves in the axial direction, the pin 18 is guided by the cam groove 19, and the cap removal part 14 is horizontally moved in a spiral shape. Rotate in the direction. Such a cap removal part 14
As a result of the operation, the cap is removed from the spout and the filling head 12 descends unhindered toward the spout and engages with the spout. The piston 17 is connected to a piston 21 applied by a pneumatic motor via a rod ρ, and the piston 17 is driven in the axial direction by the operation of the motor (operation by compressed air). The filling head 12 is slidably attached to the cylinder 16 via an auxiliary frame O, and an air damping device consisting of an air chamber U and a piston 5 is provided in the auxiliary frame. Piston 5 seeds 1 to fill
When the auxiliary frame O falls and engages with the discharge port, the air enters the air 424.

A cylinder to which the motor is applied is installed in the auxiliary frame B.

To explain the operation of the mechanism, first, the capped outlet of the bag is inserted between the outlet holder 13 and the cap removal part 14, the switch is turned on, compressed air is supplied to the motor, and the piston 21 is raised. urge As the piston 21 rises, the piston 17 and the cap removal part 14 also rise. Then, due to the engagement of the cam groove 19 and the pin 18, the discharge port holder 13 is rotated in a spiral manner, and the cap is removed from the downward path of the filling head 12. Due to the cam groove 19. Since the stroke of the piston 718 is shorter than the stroke of the piston 21, the auxiliary frame n slides downward along the cylinder 16. The movement of the auxiliary frame in the axial direction becomes gradual due to the interaction between the air chamber and the piston 5.

The movements of the discharge port holder 13 and the filling head 12 are synchronized, and at the same time as the filling head 12 begins to descend, the cap removal part 14 also performs a spiral rotation.
2 is guided by the air chamber 5 and the piston 5 and K that operate in conjunction with it, so that the cap removal part 14 is reliably separated from the downward direction of the filling head 12.

As shown in Figure 2.3, the cap removal part 14 has a pair of jaws for gripping the cap, and the discharge port holder 13 has a fixed jaw as shown in Figure 4. The auxiliary frame has a movable frame that cooperates with the fixed frame to grip the discharge port. The movable jaw is moved by the pneumatic motor 31 in synchronization with other mechanical parts of the discharge device 10, and when the discharge port is located between the fixed jaw and the movable jaw, the switch is turned on. The motor 31 is driven and the movable shaft I is pivoted to flange the discharge port together with the fixed shaft 4. Once the bag is filled,
The motor 31 is driven again, pivoting the movable jaw in the direction opposite to the flange direction, and expelling the discharge port between it and the fixed jaw outward.

Figure 5.6 shows another embodiment of the present invention, in which a bag filling device made of plastic or metal foil paper is used to fill bags with a bag similar to the above.

The filling device (3) includes a main frame 51, a discharge port holder 52, a cap removal portion &, and has a filling head (not shown) like the device 10 shown in FIGS. 1-4.

An auxiliary frame supporting the pneumatic motor is also provided between the filling devices, and, like the device 10 (FIGS. 1 to 4), a frame 6 for spirally rotating the cap removal portion 53 is not shown. The filling head also engages the spout by axial movement of the auxiliary frame, as in the device 10 (FIGS. 1-4).

The filling device differs from the filling device 10 in the discharge port holder 52, which will be explained with reference to FIG.

As shown in FIG. 6, the discharge port holder 52 has a main frame 57 with a movable holder that forms a recess 59 into which the discharge port fits, and when the discharge port is fitted into the recess 59, the switch is activated. Upon entry, the pneumatic motor ω moves, which causes the movable barrel to rotate clockwise and bring the discharge port directly below the filling head. When the bag is filled, the movable jaw is moved back counterclockwise by the motor ω, and the discharge port fitted in the recess 59 touches the protruding par 61, and the discharge port fits into the recess. It is projected outward from 59.

The filling head described above is also used to evacuate the bag before filling with liquid.
