The operation of the separation mechanism 1C using the separation arm will be described below with reference to FIG.

As shown in FIG. 6 (a), when it is detected that the packaged product 2 from which the packaging material has been cut by the cutter 4 moves on the alignment table 6 and comes into contact with the stopper 9, the separation at the initial position is performed. The telescopic drive section 142 of the scraping arm 17 provided on the arm 12 is driven to move the scraping arm 17 to the leftmost end of the separation arm 12 as shown in FIG.

When the tip of the scraping arm 17 is positioned on the alignment table 6, the vertical drive unit 140 is driven. As shown in FIG. 6 (c), the arms 17a, 17b, and the width adjustment shaft 17d descend along the vertical axis 17c, and come into contact with the upper part of the pack product 2 on the alignment table 6. At this time, when a resistance value equal to or greater than a predetermined value is detected, the vertical drive unit 140 stops driving.

At one end of a stopper 9 provided on the alignment table 6, a rotary motor 9a is provided on the lever holding portion 8 side here.
As shown in (c), the rotation motor 9a is driven to tilt the stopper 9 rightward in the drawing by 90 °.

When 7 returns to the initial position, the rotation motor 9a is driven again to return the stopper 9 to the original position. In FIG. 6D, the pack product 2 is fixed and held in the separation arm 12 by the raking arm 17 and the bottom plate 18.

Next, the rotation driving means 130 is driven to rotate the separation arm 12 rightward on the drawing with the rotation shaft 16 as a base point as shown in FIG. At this time, the separation arm 12 abuts against the impact bar 13a, and the contents of the pack product 2 fall from the cut portion of the packaging material due to centrifugal force and impact force,
It enters the food receptacle 14 shown in FIG.

When the impact detector 13 (FIG. 3) detects the impact received by the impact bar 13a, as shown in FIG.
The rotation driving unit 130 rotates leftward in the drawing, and the separation arm 12 contacts the impact bar 13b.

The food receiver 14 shown in FIG. 1 is provided with a weight detector (FIG. 3), and if there is no change in weight even if the impact of the impact bar 13a is detected by the impact detector,
The separation arm 12 is rotated clockwise again to come into contact with the impact bar 13a. It is determined that the contents have not fallen until a change in the weight of the food receiver 14 is detected.
By repeating the operation of (f), the impact bar 13b and the impact bar 1
A shock is applied to the separation arm 12 by 3a.

When the weight change of the food receiver 14 is detected,

As described above, the separation mechanism 1C using the separation arm 12 is operated to separate and collect the food, the tray and the packaging material in the 1D food receiver 14 and the tray receiver 15 shown in FIG. Each receiver can be taken out of the device and discarded separately.

The separation arm 12 and the impact bar 13a,
Since the impact force caused by the contact with the impact bar 13b is proportional to the rotation speed of the rotating shaft 16, the rotation speed may be increased at the time of contact with the impact bar 13b so that the contents can be easily dropped. Further, it is also possible to change the rotation speed depending on the type of the contents.

By adopting the following configuration, the contents can be easily dropped at the time of contact with the impact bar 13b.

For example, a side wall is provided on the conveyor 3 on the upstream side of the cutting section, and a pressing mechanism for pressing the pack goods 2 is provided on the side wall. A rail extending in the width direction and the width direction is provided, and a cutting blade movable along the rail by the cutting blade moving mechanism is provided. The cutting blade moving mechanism and the cutting blade move in the transport direction of the conveyor 3 with the movement of the alignment lever 7.

After the transport posture of the packaged food 2 is once adjusted along the side wall during the transport by the conveyor 3, the packaging material is cut by the cutter 4. Thereafter, when the packed food 2 comes into contact with the stopper 9 by the alignment lever 7, the cutting blade provided on the downstream side of the alignment lever 7 and moved together with the alignment lever 7 is first moved by the cutting blade moving mechanism in the vertical direction provided on the alignment lever 7. , That is, descends and contacts the packed food 2. If an excessive contact pressure occurs during the lowering, the cutting blade moving mechanism stops the lowering of the cutting blade.

Thereafter, the cutting blade moves along the rail in the width direction provided on the alignment lever 7 by the cutting blade moving mechanism.
The packaging material of the packed food 2 is cut in the width direction of the conveyor 3 by moving the cutting blade from the lever holding portion 8 side.

When the cutting blade moves from the lever holding portion 8 side and comes into contact with the alignment plate 10, the cutting blade moving mechanism detects the contact pressure and stops moving.

In order to shorten the time, the cutting blade is returned to the lever holding portion 8 along the rail in the width direction during the movement of the alignment lever 7 as shown in FIG. 4D, and then along the rail in the vertical direction. Although the cutting blade may be moved, the cutting blade in contact with the alignment plate 10 is returned to the lever holding portion 8 side while maintaining the same height with respect to the conveyor 3 to more reliably pack the packed food 2. The material may be cut and then moved along the vertical rail during the movement of the alignment lever 7 to return to its original position.

Next, another embodiment of the separation mechanism unit which replaces the separation arm will be described with reference to FIGS. 7 and 8. FIG.
