The CPU controls each part and controls the entire cutting / discharging device by executing various programs stored in the ROM, for example.

The control unit drives and controls each unit, and since the control of cutting the strip-shaped material to generate a single-wafered product and then depositing it on the sedimentary part is already known, the description thereof is omitted and is characteristic. I will explain only the important parts.

The control unit of the present embodiment moves the peeling unit 110 and the lower second transport unit 120 according to a predetermined cut length by driving and controlling the moving unit 150.

The drive control of the moving unit 150 may be performed manually by the operator or automatically according to a predetermined cut length.

Specifically, in the case of manual operation, for example, although not shown, the cutting / discharging device S includes an operation unit in which the operator defines the movement direction of the movement unit 150, and the operation of this operation unit drives the movement unit 150. The actuator 156 that functions as a motor is driven and controlled to move the casing 130 by a predetermined amount of movement. In this case, as shown in FIG. 5, a reference index 170 is provided at the lower end of the casing 130, a plurality of indexes 175 according to the cut length are provided in the frame RF, and the operator makes a predetermined cut.

The drive unit is driven and controlled based on the input of, and the casing 130 is moved by a predetermined movement amount according to the cut length information.

More specifically, in the control unit, when the tip of the cut leafy vegetables 2a is sucked and transported by the upper second transport unit 85 based on the cut length information, the trailing end is the lower second transport. The moving unit 150 is driven and controlled so that the casing 130 is moved in the transport direction of the single leafy vegetables 2a so as to be transported while being sucked by the unit 120, and the distance between the casing 130 and the upper second transport unit 85 is adjusted. Further, the control unit drives and controls the moving unit 150 so that the rear end of the single leaf 2a is released from the suction transport by the lower second transport unit 120 before the single leaf 2a comes into contact with the contact body 90. And move the casing 130.

As described above, the cutting / discharging device S of the present embodiment moves the casing 130 according to the cut length of the single leafy vegetables 2a to reduce the distance between the lower second transport unit 120 and the upper second transport unit 85. adjust.

As a result, the sheet paper 2a is transported while being maintained in a pulled state, and immediately before the front end thereof comes into contact with the contact body 90, the rear end portion of the sheet sheet 2a is formed by the belt 121 of the lower second transport unit 120. The sheet paper 2a is released from the suction transport and falls to the deposit portion 20 due to the drop due to its own weight. Since the single leafy vegetables are maintained in a pulled state until just before the fall, the single leafy vegetables fall without losing their shape, and the single leafy vegetables 2a are accurately and properly deposited in the deposit portion 20.

Next, a series of operations of the cutting / discharging device S will be described with reference to FIGS. 1 to 5.

First, as shown in FIGS. 1, 2, or 4, in the cutting / discharging device S, the tip of the cut leafy vegetables 2a is sucked and conveyed by the upper second transport unit 85 by the drive control by the control unit. At that time, the rear end is transported while being sucked by the lower second transport unit 120, and immediately before the tip of the single leaf 2a comes into contact with the contact body 90, the rear end of the single leaf 2a is transported to the lower second transport. The casing 130 is moved in the A or B direction according to the cut length of the single leafy vegetable 2a so as to be released from the suction transfer by the unit 120.

Specifically, when the cut length is long, the casing 130 is moved in the B direction, that is, in the direction away from the upper second transport unit 85 as shown by the solid line in FIG. 1, and when the cut length is short, the A direction. That is, as shown by the dotted line in FIG. 1, the casing 130 is moved in the direction close to the upper second transport unit 85.

Next, in the in-feed unit 30, the strip-shaped object 2 is sent out to the lower first transport unit 35 in a state where the entire width direction is nipped on the surface of the strip-shaped object 2 by the drive of the draw roller 31, and the belt of the lower first transport unit 35. While being sucked on 36, it is sent out to the cutting portion 10.

Next, the strip 2 is cut by the rotary cutter 11 at the cutting portion 10. At the time of this cutting, the tip of the strip 2 passes through the rotary cutter 11 before entering the cutting posture, is delivered to the belt 46 of the upper first transport unit 45, and is sucked by the belt 46 on the downstream side. Will be transported to. Therefore, the strip 2 is pulled between the lower first transport unit 35 and the upper first transport unit 45 with an appropriate force, and immediately after that, it is cut by the rotary cutter 11.

Since the belt 46 of the upper first transport unit 45 travels at a slightly higher speed than the belt of the lower first transport unit 35, the belt 46 is between the rear end of the leafy vegetables 2a generated by cutting and the tip of the strip-shaped object 2. There is a gap. This makes it possible to prevent the tip of the succeeding strip 2 from colliding with the rear end of the preceding single leaf 2a.

While the tip of the leafy vegetables 2 is delivered to the upper second transport unit 55 via the upper first transport unit 45 and the intermediate transport unit 65, the rear end of the single leafy vegetables 2a is peeled off below the unit 110. Will be transported to.

Then, as shown in FIG. 2, the brush 111 of the peeling unit 110 pushes down the rear end portion of the leafy vegetables 2a from the belt 46 of the upper first transport unit 45 against the suction force of the suction roller 125. When pressed against the surface, the rear end portion of the single leafy vegetable 2a is attracted to the surface of the suction roller 125 and curves according to the surface.

Further, since the belt 56 of the upper second transport unit 55 travels at a lower speed than the belts 46 and 66 of the upper first transport unit 45 and the intermediate transport unit 65, the tip of the succeeding sheet leaf 2a is a preceding sheet. While sneaking under the leafy material 2a, it partially overlaps with the preceding single leafy material 2a and is transported.

Further, since the belt 56 of the upper second transport unit 55 travels at a slightly higher speed than the belt 121 of the lower second transport unit 120, the single leafy vegetables 2a are transported in a pulled state.

The amount of overlap between the preceding single leafy vegetables 2a and the subsequent single leafy vegetables 2a is the speed difference between the belt 56 of the upper second transport unit 55 and the belts 46 and 66 of the upper first transport unit 45 and the intermediate transport unit 65. Therefore, the rotation speed of each drive shaft may be controlled.

The tip of the leafy vegetables 2a conveyed by the belt 56 of the upper second conveying unit 55 in this way comes into contact with the contact body 90. At this time, since the rear end portion of the single leafy material 2a is separated from the transport by the lower second transport unit 120 and the subsequent single leafy matter 2a overlaps with the central portion thereof, the belt 46 of the upper first transport unit 45 When the tip comes into contact with the contact body 90, it falls downward due to its own weight and is sequentially stacked on the deposit 20 because only the tip is sucked by the upper second transport unit 55. It is possible to deposit a plurality of single leafy vegetables 2a that are deposited and are reliably and accurately transported at high speed.

In this way, the casing 130 is moved according to the cut length of the leafy vegetables 2a, and the distance between the lower second transport unit 120 and the upper second transport unit 85 is adjusted, so that the casing 20 is transported to the depositing portion 20 at high speed. A plurality of leafy vegetables 2a having different lengths can be reliably and accurately deposited.
