Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically discharging a filling material in an automatic packaging machine for food or the like.

[0002]

2. Description of the Related Art FIG.
Alternatively, when the container 1 containing the arbitrarily determined amount of the packing material is sequentially conveyed by the conveyor 2, the traveling is temporarily stopped by the locking bars 12a and 12b, and then the front locking bar 12a is moved. Only one container 1 at the top
Is introduced into the guide cylinder 13 and is turned upside down to be received by the stopper plate 14. With this operation, the contents in the container are discharged and supplied to the prepared bag or can 16 via the hopper 15.

On the other hand, the empty container after discharging the filling material slides down the guide plate 18 by driving the cylinder 17 and inclining the guide tube 13, and is discharged and collected to the outside by a discharging means such as a conveyor. Becomes

[Problems to be solved by the invention]

[0004] In the above-mentioned conventional discharging device, the container on the traveling conveyor is naturally dropped by the function of the locking bar, and the container is turned upside down to discharge the filling. In some cases, the filling material easily adhered to the container, and was not completely discharged simply by inverting the container. In addition, the container may not be turned upside down and the filling material may not fall into the hopper without fail.

[0005]

This invention SUMMARY OF THE INVENTION has been made to St. solve the above problems, lower the container to both ends in arms which are rotatably supported a central portion it is an feature A gripping means having a pair of gripping parts for gripping or releasing, and a reversing means for reversing and moving the gripping means at a predetermined angle, a container for storing a filling therein and being conveyed by a conveyor, Hold the gripping means at a predetermined angle 1
In a configuration in which rotation stop is repeated in the direction, the packing is discharged by alternately gripping or releasing the pair of gripping portions.

[0006]

The container is alternately gripped or released by the pair of gripping portions while the rotation of the gripping means is stopped in one direction, so that the container filling can be discharged timely and continuously without remaining. Can be done.

[0007]

1 and 2 show the device of the present invention. FIG. 1 is a partially cutaway side view and FIG. 2 is a plan view thereof. Reference numeral 1 denotes a container, which is sent by a conveyor 2. 3 is an automatic reversing means comprising disposed on the other party position, in the vicinity of both edges of the arm 4 which is pivotally supported by a shaft O ₁ respectively is 1
A pair of grips 5 are formed.

Here, the configuration of each grip 5 is as follows. In this embodiment, both ends of the arm 4 are formed in mutually opposite L-shaped steps m, and a pressing piece 5a of a fixed length is rotatably attached to the base of each step via the pin 6. At this time, one end of the pressing piece 5a is formed in a bent claw portion p, and the other end is provided with a cam follower 7 and a spring 8 to elastically move the claw portion p in the closing direction toward the arm 4 side. Tow.

Reference numeral 9 denotes an axis O mounted coaxially with the axis of the arm 4.
_The cam 9 is integrally attached to the cam ₃ so that the cam 9 and the cam follower 7 are engaged with each other.
Reference numeral 10 denotes an angle indexing device, wherein the axes O ₁ and O ₃ are attached to the angle indexing device, and control the rotation of the motor 11 to move the axes O ₁ and O ₃ by a predetermined angle based on a predetermined command. It is designed to rotate.

[0010] That is, the axis O ₃ of the driven by-off as shown via the cam follower 7 a pressing piece 5a by a dotted line in the drawing by rotating the cam 9 by a predetermined angle claw portion p and the arm 4 L The container 1 is gripped or released between the stepped portions m. At this time, the operation of each of these gripping portions is opposite to one operation of the cam 9, and when one of the gripping operations is performed, the other performs the releasing operation. Also axis O ₁
Is driven to rotate the arm 4 by 180 ° so that the container 1 held between the holding portions is
The container is reversely driven by 0 ° to discharge the filling in the container into the guide cylinder.

In this way, when the containers are conveyed on the conveyer 2, the traveling is temporarily stopped by the locking bars 12a and 12b. Next, when the front locking bar 12a is retracted and the container 1 reaches the end position of the conveyor 2, the angle indexing device 10 is moved.
Operates to drive the cam 9 to grip the container 1 from above and below between the claw portion p of the pressing piece 5a and the L-shaped step m at the tip of the arm 4.

Subsequently, the angle indexing device 10 is operated, and the axis O
₁ to drive the container 1 through the arm 4 at a predetermined speed for 180
Invert only by ゜. Then, the rotation of the arm 4 is stopped at a position where the container 1 has reached the inside of the guide tube 13. Then, all the filling in the container 1 is reliably discharged into the hopper 15 by receiving the inertial force. When the filling is completely discharged, the cam 9 is turned off.
When the pressing piece 5a is released as indicated by the alternate long and short dash line, the empty container falls in the guide cylinder 13 and hits the stopper plate 14 and stops. Then, the cylinder 17 is operated to guide the guide cylinder 13.
When the container is tilted, the empty container slides down the guide plate 18 and is discharged and collected separately by a conveyor or the like.

In the above gripping reversal operation, when one of the pair of grippers 5 is performing a gripping operation on the right side in the illustrated example, the left gripper side is simultaneously performing a releasing operation. This operation is repeatedly performed by rotating the arm 4 by 180 °. In this manner, the arm 4 is repeatedly rotated and stopped by 180 ° in the same direction, and the containers are sequentially released by the pair of gripping portions, whereby the reversing and discharging operations are continuously and efficiently performed.

[0014]

As described above, the automatic reversing and discharging device according to the present invention stops the rotation of the arm provided with the pair of grips by a predetermined angle, and according to the operation, the container having the configuration of the pair of grips. Are alternately gripped or released.
The filling in the container is reliably discharged without remaining, and the reversing discharge operation is continuously and efficiently performed.
