Hereinafter, the configuration of the food dough cutting device according to the embodiment of the present invention will be described with reference to the drawings.

As conceptually and schematically shown in FIGS. 1 and 2, a food dough cutting device 1 according to an embodiment of the present invention is, for example, a castella wrapped in a pie dough and baked into a required size (long length). A food dough piece P having a predetermined cutting length (target cutting length LT) is cut from the bar-shaped food dough D of (S).

The food dough cutting device 1 is provided with a supply conveyor 5, a cutting device 7, and a carry-out device 9 on a gantry 3. Further, the food dough cutting device 1 has an appropriate control device 11 such as a computer and an input/output device 12. The control device 11 is connected to the supply conveyor 5, the cutting device 7, the carry-out device 9, and the output/input device 12.

The supply conveyor 5 is a belt conveyor, and intermittently conveys the rod-shaped food material D in the conveyance direction A. The supply conveyor 5 includes a drive motor 5a, a conveyor belt 5b, and an encoder 5c that generates a pulse corresponding to the transport distance of the rod-shaped food dough D.

Further, a cutting device 7 for cutting the food dough D is provided above the feeding end of the supply conveyor 5 (on the left side in FIG. 1). The cutting device 7 includes a flat cutting blade 7a and a moving portion 7b. The cutting blade 7a is, for example, an ultrasonic cutter. Further, the moving portion 7b includes an elevating mechanism 7c such as an endless belt that is normally and reversely rotated by a servo motor, a ball screw mechanism, a fluid pressure cylinder, etc., and reciprocates the cutting blade 7a up and down.

The carry-out conveyor 9 is arranged adjacent to the downstream side of the carrying end of the supply conveyor 5. The carry-out conveyor 9 is a belt conveyor and includes a drive motor 9a and a conveyor belt 9b. The carry-out conveyor 9 carries the food dough piece P cut by the cutting device 7 in the carrying direction A.

The carry-out conveyor 9 is provided with an optical sensor S as a detection device for detecting the presence or absence of the rod-shaped food dough D or the food dough piece P on the side of the upstream (right side in FIG. 1) end of the carry-out conveyor 9. .. The detection device S can be appropriately selected, for example, a limit SW or a CCD camera. In addition, in this embodiment, the optical sensor S and the cutting blade 7a have a space|interval along the conveyance direction A. FIG. This interval is referred to as the initial interval LA.

The input/output device 12 is, for example, an operation panel such as a touch panel, and has functions as an input device 12a and an output device 12b. The input device 12a inputs and sets the operating conditions of each unit in advance. The output device 12b displays the operating status of each unit. In the embodiment of the present invention, the target cutting length LT of the food dough piece P, the re-driving time T described later, and the like are input to the input device 12a.

Next, the operation of the food dough cutting device 1 will be described with reference to FIGS. 3 to 6. In the above configuration, the rod-shaped food dough D is placed on the supply conveyor 5, and the food dough cutting device 1 is driven under the control of the control device 11. The cutting blade 7a of the cutting device 7 stands by at the rising end. The supply conveyor 5 and the carry-out conveyor 9 are driven at the same transport speed V, and the rod-shaped food dough D is transported in the transport direction A (see FIG. 3 ).

The tip (downstream end) DF of the rod-shaped food dough D is detected by the sensor S (see FIG. 4). A detection signal and a pulse are transmitted from the encoder 5c to the control device 11 with this point as a base point, and the post-sensing transport distance LB of the rod-shaped food material D is calculated. When the sum of the initial distance LA between the cutting blade 7a and the optical sensor S and the post-sensing transport distance LB matches the target cutting length LT, that is, the control device 11 causes the tip DF of the rod-shaped food dough D to the cutting device 7. Stops the driving of the supply conveyor 5 and the carry-out conveyor 9 at the position corresponding to the distance corresponding to the target cutting length LT, and stops the conveyance of the food dough D (see FIG. 5 ). Then, the control device 11 instructs the cutting device 7 to lower the cutting blade 7a to the lower end, and cut the food dough piece P having the target cutting length LT from the rod-shaped food dough D. Then, the cutting blade 7a is raised and stopped at the rising end.

When the cutting blade 7a cuts the rod-shaped food dough D, the remaining rod-shaped food dough D is opposite to the conveying direction A on the conveying surface of the supply conveyor 5 due to the influence of the thickness of the cutting blade 7a and the descending speed of the cutting blade 7a. It is pushed back in the anti-transport direction B. Here, the distance from the cutting blade 7a (in the present embodiment, the left side surface of the cutting blade 7a in FIG. 5) to the new tip DF of the remaining rod-shaped food dough D is defined as the sliding distance LC. In this embodiment, an ultrasonic cutter is used as the cutting device 7. Since the thickness of the cutting blade of the ultrasonic cutter is thicker than that of a general plate-shaped guillotine blade, there is a strong tendency to push back the remaining rod-shaped food dough D. It should be noted that this sliding distance LC changes every time cutting is performed, and is not a preset value.

The controller 11 restarts the driving of the supply conveyor 5 and the carry-out conveyor 9, and conveys the rod-shaped food dough D and the food dough piece P at the conveyance speed V, respectively. The optical sensor S detects the passage of the food dough piece P, and as shown in FIG. 4, detects the new tip DF of the remaining rod-shaped food dough D. In the food dough cutting device 1, the cutting device 7 cuts the next food dough piece P through the same steps as described above. By repeating these steps, a plurality of food dough pieces P having the target cutting length LT are cut from the rod-shaped food dough D.

In the conventional food dough cutting device, since the cutting blade has driven the supply conveyor by the distance corresponding to the target cutting length LT with the position where the bar-shaped food dough is cut as a base point, the food dough piece to be cut next is The length corresponding to the sliding distance LC was shorter than the target cutting length LT. According to the food dough cutting device 1 according to the embodiment of the present invention, the optical sensor S as a detection device detects the tip DF of the pushed rod-shaped food dough D, and the control device 11 uses this detection signal as a base point. Since the transport position of the remaining rod-shaped food dough D can be calculated for each cutting, the transport of the distance corresponding to the target cutting length LT of the rod-shaped food dough D with respect to the cutting position of the rod-shaped food dough D by the cutting device 7 can be accurately performed. Therefore, the food dough piece P having the target cutting length LT can be reliably cut from the rod-shaped food dough D.

In addition, when the cut food dough piece P is a thin piece, when the food dough piece P is conveyed by the conveyor 9, the remaining stick-shaped food dough D is converted into the remaining stick-shaped food dough D as shown by a two-dot chain line in FIG. The food dough piece P'may tilt. In this case, the optical sensor S senses the food dough piece P′ and cannot properly sense the new tip DF of the remaining rod-shaped food dough D. Even in such a case, the detection device S needs to reliably detect the tip DF of the food dough piece D.

In the embodiment of the present invention, after the carry-out conveyor 9 is re-driven, the re-driving time T is provided before the supply conveyor 5 is re-driven so that the fallen food dough piece P is separated from the rod-shaped food D. The re-driving time T can be appropriately set in relation to the height H of the rod-shaped food dough D, the transport speed V, and the like, and is preset in the input device 12a.

In this re-driving time T, the distance LB from the tip (the left end in FIG. 6) of the fallen food dough piece P to the cutting blade 7a is a predetermined distance (the distance corresponding to the height H of the food dough piece P or more). It is desirable that the time is the above. By driving only the transport conveyor 9 first with respect to the stopped supply conveyor 5, the tumbled food dough piece P can be reliably separated from the remaining stick-shaped food dough D on the supply conveyor 5. Then, by re-driving the supply conveyor 5 and carrying the remaining stick-shaped food dough D, the optical sensor S as a detection device can appropriately detect the tip DF of the stick-shaped food dough D, and the stick-shaped food dough D can be stably obtained. Can be cut.

As can be understood from the above description, according to the food dough cutting device 1 according to the embodiment of the present invention, it is not necessary to provide a conventional pusher for pushing the rear end surface (butt surface) of the food dough, and a rod-shaped or It is possible to reliably and stably cut the food dough piece P having the predetermined target cutting length LT from the flat food dough D.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and various modifications can be made within the scope of the invention described in the claims, Needless to say, these are also included within the scope of the present invention.

In the food dough cutting device 1 according to the embodiment of the present invention, the mounting position of the optical sensor S with respect to the cutting blade 7a can be movably provided. In particular, when the target cutting length LT of the food dough piece P to be cut is relatively short, it is necessary to narrow the initial distance LA between the cutting blade 7a and the optical sensor S. When changing the mounting position of the optical sensor S, the parameters input to the control device 11 are changed to correspond.

Furthermore, by making the sensing position of the detection device S coincide with the cutting position of the rod-shaped food dough D by the cutting blade 7a, it is not necessary to provide the initial interval LA, and the control device 11 causes the detection device S to detect the rod-shaped food dough D. It is also possible to calculate the transport distance corresponding to the target cutting length LT with the time point when the tip DF is sensed as the base point.

Further, the explanation has been made by providing the re-driving time T until the supply conveyor 5 is re-driven after the carry-out conveyor 9 is re-driven, but for example, a pulse corresponding to the carry distance of the food dough piece P is given to the carry-out conveyor 9. It is also possible to separate the cut food dough piece P from the remaining rod-shaped food dough D by a predetermined distance by providing a generating encoder and providing a re-driving conveyance distance. That is, the re-driving time T or the re-driving conveyance distance can be provided as the food dough piece separating means in the food dough cutting device 1 so as to be controllable by the control device 11.

Even if the food dough piece P does not fall, the detection device S can stably detect the tip DF of the food dough D by sufficiently separating the food dough piece P and the remaining food dough D. Therefore, it is useful to use the food dough piece separating means.

Further, the input device 12a is provided in the input/output device 12 which is an operation panel such as a touch panel, and the target cutting length LT of the food dough piece P, the re-driving time T, or the re-driving conveying distance is input by the input device 12a. As described above, it is possible to directly connect the input device to the control device 11 and input the set values thereof.

Further, in the above embodiment, the target cutting length LT is described as one set value, but the value can be changed during the production. For example, the end surface of the rod-shaped food material D prepared to have a required size is not flat but has irregularities, which may be inappropriate as a final product. In such a case, when the food dough piece P having the target cutting length LT is cut from the end portion of the food dough D, the food dough piece P does not become a product and the productivity is reduced.

Therefore, by setting the first target cutting length LT1 to, for example, 5 mm and the second and subsequent target cutting lengths LT2 to, for example, 30 mm, it is possible to reduce the waste rate and improve the productivity. This is to input the target cutting lengths LT1 and LT2 to the control device 11 and further to have a counting function relating to the number of times of cutting, and based on the detection signal from the detection device, determine the first cutting length and the second and subsequent cutting lengths. Control to change is possible. Similarly, it is possible to cut several kinds of food dough pieces P having different cutting lengths from one food dough D.
