Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a discharging device for a filling material in an automatic packaging machine for food or the like.

[0002]

[Prior Art]

 FIG. 4 shows a conventional automatic reversing and discharging device, in which a container 1 stores a filling and is conveyed on a belt conveyor 2. At the end 2a of the conveyor 2, there is installed a swing arm 13 which is connected to this, that is, supported by a shaft 12 and rotated by a cylinder 15. On the upper surface of the revolving arm 13, a mounting plate 11 having a locking claw 11a for locking the container 1 at its tip and having a slit hole 11b at the substantially central portion is attached. Further, a protruding rod 17 is provided upright below the revolving arm 13 so as to correspond to the slit hole 11b, and a stopper 18 is attached at a position slightly outside the revolving locus of the revolving arm 13. ..

In such a conventional apparatus, the container 1 conveyed on the belt conveyor 2 is temporarily stopped by the stoppers 4a and 4b, and then the front stopper 4a is retracted to place only one container. Move to plate 11 and stop. In this state, the cylinder 15 is operated to tilt the turning arm 13 by turning. Then, the rod 17 protrudes through the slit hole 16 and pushes up the bottom of the container 1, so that the container 1 further tilts and comes into contact with the stopper 18, and the container 1 is inverted around the contact point and dropped into the guide tube 3. To do.

At the end of the dropping motion, the stopper plate 7 provided at the bottom of the guide cylinder 3 collides with the stopper plate 7 and stops, and the impact of the collision effectively discharges all the filling in the container 1 and the hopper 5 After that, it is supplied and filled into the bag. Then, the empty container 1 from which the filling is discharged is discharged and collected to the outside by the discharge conveyor 10 via the guide plate 9 by inclining the guide cylinder 3 by the cylinder 8.

[0005]

[Problems to be solved by the device]

 In the conventional device as described above, the container falling in the guide cylinder is received by the circular peripheral edge provided at the bottom of the guide cylinder, so that there is a drawback that a considerable amount of filler remains on the peripheral edge of the stopper. .. Although the guide tube is tilted to be delivered and discharged onto the carry-out conveyor, the container may tip over on the conveyor due to the downhill speed, and the container may not be discharged in the correct posture, which will interfere with the subsequent process. Will be Furthermore, the conveyors used for discharge and recovery have high equipment costs and require a large installation space.

[0006]

[Means for Solving the Problems]

 The present invention is intended to solve the above-mentioned problems, and is characterized by a locking claw that is swingably installed at the bottom of the guide cylinder to receive a falling container, and the guide cylinder. The structure is provided with an abutting rod for releasing the locked state of the container by rotating the locking claw when the container is tilted by the tilting means, and a chute for collecting the container sliding down from the tilted guide cylinder.

[0007]

[Action]

 The locking claw installed on the bottom side surface of the guide tube catches the falling container and discharges the filling material. Therefore, all the filling material is discharged without remaining on the bottom of the guide tube. It will be one. Also, when the guide tube is tilted, the locking state of the locking claws is automatically released, which allows the container to be discharged and recovered through the recovery chute.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. 1 is an overall front view of the device of the present invention, FIG. 2 is a partial plan view taken along the line AA of FIG. 1, and FIG. 3 is a partial side view taken along the line BB of FIG. In the above description, the same components as those of the above-mentioned prior art are designated by the same reference numerals and the description thereof will be omitted. In the present invention, an L-shaped locking claw 22 is swingably attached to the lower portion of the guide tube 3 via a bracket 20. Here, the tip claw portion 22a of the locking claw 22 is made to slightly project into the guide cylinder 3 so as to receive the falling container, and is normally pulled through the spring 19 toward the guide cylinder 3 side. It is designed to be. The guide cylinder 3 is tilted by the cylinder 8 as shown by the alternate long and short dash line. At that time, the guide cylinder 3 is brought into contact with the side of the locking claw 22 opposite to the claw portion 22a to swing the locking claw 22. In addition, an abutting rod 23 is provided for opening the container 1 in the locked guide tube 3.

Further, a chute 21 is installed at a position where it is connected to the outlet of the guide cylinder 3 which is further inclined so that the container 1 sliding down in the guide cylinder 3 is received and collected. FIG. 3 shows a cross section of the chute 21, and a wire-shaped guide 21a for assisting the sliding down of the container 1 is laid on the inner bottom surface thereof.

Next, the operation of the device of the present invention will be described. The container 1 conveyed on the belt conveyor 2 is temporarily stopped by the stoppers 4a and 4b, then the front stopper 4a is retracted and only one container is moved onto the mounting plate 11 and stopped. In this state, the cylinder 15 is operated to swing and tilt the swing arm 13. Then, the projecting rod 17 pushes up the bottom of the container 1 through the slit hole 11b, so that the container 1 further tilts and comes into contact with the stopper 18, and the container is inverted about the contact point and falls in the guide tube 3. .. Then, at the end of the drop motion, the container 1 is received by the claw portions 22a of the locking claws 22 projecting to the bottom of the guide cylinder 3, and the impact at that time causes the filling material in the container 1 to be completely discharged. .. Thus, the discharged filler is not retained at the bottom of the container 1 but remains in the bag (not shown) through the hopper 5 and is filled. On the other hand, in the empty container 1 from which the filling has been discharged, when the guide tube 3 is tilted by the cylinder 8, the locking claw 22 that locks the container 1 abuts against the butting rod 23 and rocks, When it is released, it slides out of the guide cylinder 3 and is handed over to the chute 21, and the slide 21 smoothly slides down and is discharged and collected to the outside.

[0011]

[Effect of the device]

 As described above, in the discharging device of the present invention, the locking claw 22 swingably installed on the bottom of the guide tube 3 catches the falling container 1 and discharges the filling material. All will be discharged cleanly without remaining at the bottom. Also, the locking claw that receives the container abuts against the abutment rod 23 when the guide tube is tilted and swings, and the locked state is automatically released, and the chute effectively and efficiently. Since it is possible to efficiently and hygienically discharge and collect the filling material with a simple structure such as being discharged and collected to the outside, the equipment cost is particularly low.
