When the feed weight of the food dough W per unit time is smaller than the target achievement value, the control unit 29 enlarges the average discharge gap (or the minimum discharge gap) and sends the food dough W per unit time. Is larger than the target set value, the operation of the gap adjusting motor 105 can be controlled so as to reduce the average discharge gap (or the minimum discharge gap).

The pressing hopper 15 can be omitted by providing the press feeding device 17 with a function of sufficiently accommodating the food dough W, in other words, a function as a hopper.

Next, the operation of the embodiment of the present invention will be described.

The cutting of the food dough W is started by the corresponding pair of cutters 23 by synchronously rotating the pair of rotary shafts 21 in the feed direction (the direction a in FIG. 2) by the operation of the split motor 25. Next, the rear support portion 55 of the belt 53 is moved upward by the operation of the air cylinder 61 to hold the food dough W from below. further,
By rotating the pair of rotating shafts 21 in the feeding direction and bringing the corresponding tips of the pair of cutters 23 into contact with each other, the lower opening of the dividing hopper 9 is closed. As a result, the food dough W can be divided and formed by the corresponding pair of cutters 23.

After the food dough W has been divided and formed, the rear support portion 55 of the belt 53 is moved downward by the operation of the air cylinder 61 so as to be positioned at a position where the load detector 67 can detect it. The food dough W divided and molded by 13 is conveyed forward. At this time, the load acting on the rear support portion 55 by the food dough W is detected by the load detector 67. And food dough W
Is transported forward, the rear support portion 55
When the predetermined load is detected by the load detector 67, in other words, the weight of the portion of the food dough W located behind the reference position (the intermediate roller 43) is reduced to the predetermined load. When the weight value reaches the value corresponding to the food dough W, the control means 29 operates the split motor 25 to
Is performed. As a result, the front end of the divided food dough W can overlap the rear end of the food dough W being transported (the immediately preceding divided food dough) W from above. In, belt conveyor 1
3, the food dough W can be transported forward.

Here, in the front inclined support portion 57, the joining state of the overlapping portion of the food dough W (the front end of the divided food dough W and the rear end of the preceding food dough W) is stabilized by the action of its own weight. I do. Further, in the front inclined support portion 57, the overlapping portion of the food dough W is deformed by the rotating pressing roller 73 so as to be thin, and the joining state of the overlapping portion is strengthened.

When the food dough W is conveyed forward by the belt conveyor 13 in a state where the front end of the divided and formed food dough W overlaps the rear end of the preceding food dough W, the belt conveyor 13 Is fed into the pressing hopper 15 from the front end of the food dough. The plurality of front-side press feed rollers 91F and the plurality of rear-side press feed rollers 91R are rotated in the feed direction (the direction b in FIG. 6) by the operation of the press feed motors 93F and 93R.
A pair of front and rear pressing / feeding roller groups 87F and 87R can be pressed and formed into a belt shape and fed downward.

By repeating the above operation many times,
Under the condition that the front end of the divided and formed food dough W overlaps the rear end of the preceding food dough W, a large number of food doughs W can be sequentially conveyed forward by the belt conveyor 13, Food dough W by the press feed device 17
Can be continuously pressed in a downward direction by press-forming in a belt shape.

During continuous feeding by the pressing and feeding device 17, the feeding weight of the food dough W per unit time is calculated by the calculating means 111 based on the load value detected by the load detector 67. When the feed weight of the food dough W per unit time is smaller than the target set value, the control means 29 controls the gap adjusting motor 105 by the control means 29 so as to enlarge the discharge gap between the front and rear pressing and feeding roller groups 87F and 87R. Control. On the other hand, the food dough W per unit time
If the feed weight is larger than the target set value,
The control means 25 controls the gap adjusting motor 10 so as to reduce the ejection gap between the rear-side pressing feed roller groups 87F and 87R.
5 is controlled.

Further, the food dough W is
During continuous feeding of the food dough W above the discharge gap, the rear roller support member 89R is swung in a direction away from the front roller support member 89R by the operation of the discharge promotion motor 99. , The food dough W flows into the discharge gap by its own weight. Further, by pressing the rear roller supporting member 89R in a direction approaching the front roller supporting member 89F by the operation of the discharge promoting motor 99, the pressing operation of the food dough W is promoted.

As described above, according to the embodiment of the present invention, the weight of the rear support portion 55 located on the rear side of the reference position (reference roller 31) in the food dough W being conveyed becomes the predetermined load value. When the corresponding weight value is reached, the food dough W can be split and formed by the split cutter device 11, so that the weight of the overlap portion of the food dough W is reduced regardless of the shape of the end of the split and formed food dough W. It can be kept substantially constant, and when the food dough W is pressed and formed in a belt shape, the width of the overlap portion can be suppressed from being reduced, and the forming accuracy of the food dough W can be improved.
Further, the food dough W can be divided and formed by the splitting cutter device 11 in a state where the food dough W is held from below by the rear support portion 55 of the belt 53 in the belt conveyor 13, so that the divided dough is formed. The position of the food dough W on the belt 53 is prevented from varying from side to side, so that the front end of the separately formed food dough W can surely overlap the rear end of the preceding food dough W. The effect is further improved.

In the front inclined support portion 57, the joint state of the overlap portion of the food dough W is stabilized by the weight of the food dough W, and the overlap portion of the food dough W is thinned by the pressing action of the pressing roller 73. And the bonding state of the overlapping portion becomes strong, so that the food dough W can be pressed by the pressing hopper without the assistance of an operator during the continuous feeding of the food dough by the pressing and feeding device 17. 15 does not stay near the upper opening or the overlapping portion of the food dough W does not shift.

Further, when the feed weight of the food dough W per unit time is smaller than the target set value, the discharge gap between the front and rear pressing and feeding rollers 87F and 87R is enlarged and the food dough W per unit time is increased. When the feed weight is larger than the target set value, since the discharge gap is reduced, the feed weight of the food dough W per unit time can be made closer to the target set value to meet various needs of the user. Can be.

The rear support portion 55 is connected to the load detector 67.
When the reference roller 3
The center of the intermediate roller 43 is located substantially on a line connecting the center of the rear roller 37 and the center of the rear roller 37, and the rear support portion 55 is on the same plane.
Detection accuracy is improved.
