The carry-in conveyor 5 is provided with an endless conveyor belt 13 on which the food dough 3 is placed and conveyed, and is a conveyor that continuously conveys the food dough 3 at a required conveyance speed. Since the said carrying-in conveyor 5 may be a well-known structure, detailed description about the structure is abbreviate | omitted.

The cutter unit 9 is attached to a base plate 10 installed above the rear end of the carry-in conveyor 5, and four units are arranged in parallel with respect to the carrying direction of the carry-in conveyor 5. Each cutter unit 9 includes a flat blade-shaped cutter (cutting blade) 15. The cutter 15 has a flat plate shape and includes a linear cutting edge 16 at the lower end thereof. The cutter 15 is arranged such that a flat surface is perpendicular to the transport surface 6 of the carry-in conveyor 5. The four cutters 15 are arranged in series on an imaginary straight line such that their blade edges 16 are arranged along the width direction orthogonal to the conveying direction of the carry-in conveyor 5. Further, the cutters 15 adjacent to each other are provided so as to be slightly separated from each other. The cutter 15 is provided so as to freely reciprocate in the vertical direction with respect to the transport surface 6 so as to approach and separate from the transport surface 6 of the carry-in conveyor 5. The cutter unit 9 and the cutter 15 may be provided above the carry-out conveyor 11.

The cutter unit 9 includes a control actuator 19 that reciprocates the cutter 15 via a power transmission mechanism 17. The control actuator 19 uses a motor such as a servo motor that can be controlled and driven based on a command from the control device 12. The control actuator 19 is attached to the downstream vertical surface 10D of the base plate 10 so that the rotation output shaft 19S is arranged in the horizontal direction in FIG.

The power transmission mechanism 17 is a mechanism for converting the rotational motion of the rotational output shaft 19S of the servo motor 19 into a linear motion, and here a crank mechanism is used. The crank mechanism includes a drive arm 17A and a driven arm 17B. One end of the drive arm 17A is fixed to one end (left side in FIG. 2) of the rotation output shaft 19S of the servo motor 19, and the drive arm The other end of 17A is rotatably coupled to one end of the driven arm 17B. Further, the other end of the driven arm 17B is screwed into the cutter bracket 21. The cutter 15 is detachably fixed to the cutter bracket 21.

Further, a plate-like proximity body 35 is fixed to the other end (right side in FIG. 2) of the rotation output shaft 19S of the servo motor 19, and the proximity body 35 senses the proximity body 35 on the downstream vertical surface 10D of the base plate 10. A switch 33 is attached. The drive of the servo motor 19 is temporarily stopped at a position where the proximity body 35 is sensed by the proximity switch 33. In the present embodiment, the cutter 15 is stopped at the raised position and temporarily held as a standby position.

Further, a linear rail guide unit 23 is attached to the upstream vertical surface 10U of the base plate 10. The linear rail guide unit 23 includes a linear rail 23A and a slider 23B, and the longitudinal direction of the linear rail 23A is arranged along the vertical direction. The cutter bracket 21 is attached to the slider 23B. Therefore, by driving the control actuator 19 and rotating the rotation output shaft 19S once, the cutter 15 is lowered from the ascending stop position which is a standby position, and the cutting edge 16 of the cutter 15 is conveyed by the carry-in conveyor 5. The cutter 15 reciprocates linearly and intermittently along the vertical direction so as to come into contact with the conveyor belt 13 forming the surface 6 and then ascend and wait again at the ascending stop position. In addition to “reciprocating” only in the vertical direction, “straight” means that the food dough 3 is lowered while moving to the downstream side as the food dough 3 is moved, and the food dough 3 is cut. The latter includes the case of reciprocating so as to rise while moving upstream. When the cutter 15 is reciprocated while moving in the horizontal direction as described above, the base plate 10 is supported horizontally and reciprocated in synchronism with the vertical reciprocation of the cutter 15. This method can be configured.

The weighing conveyor 25 measures the food dough 3 supplied from the carry-in conveyor 5, and is close to the downstream side of the carry-in conveyor 5, and four in parallel with the carrying direction of the carry-in conveyor 11. Has been placed. The carry-out conveyor 11 is disposed close to the downstream side of the weighing conveyor 25. Since the weighing conveyor 25 and the carry-out conveyor 11 may have a known configuration, detailed description of the configuration is omitted.

The control device 12 is an appropriate control device such as a computer, for example, and a single drive mode in which each of the cutters 15 is reciprocated independently by individually controlling the control actuators 19 of the plurality of cutter units 9. And a combination drive mode in which each set is reciprocally moved by combining the cutter 15 into one set or a plurality of sets by controlling the plurality of control actuators 19 in one set or a plurality of sets. Drive selection means 29 is provided.

The drive modes will be described with reference to FIGS. FIG. 3 is an explanatory view schematically showing a single drive mode in which each of the cutters 15 is reciprocated independently, and FIG. 3A is a plan view schematically showing the food cutting device 1. b) The figure is an explanatory view of the main part as viewed in the direction of arrows AA in FIG. The control actuator 19 of each cutter unit 9 is individually driven based on a drive command from the control device 12 when the measured value of each weighing conveyor 25 corresponding to each food dough 3 becomes a set value. Each of the cutters 15 corresponding to each of the control actuators 19 cuts the food dough piece 7 from the corresponding food dough 3. Then, the conveying speed of the weighing conveyor is changed at a higher speed than during weighing, and the food dough piece 7 is separated from the food dough 3 and delivered to the carry-out conveyor 11.

Next, the combination drive mode will be described. FIG. 4 is an explanatory view schematically showing a combination drive mode in which the four cutters 15 are combined as two sets of left and right as a set and each set is reciprocated integrally. It is the top view which showed the said food cutting device 1 schematically, (b) is explanatory drawing of the principal part by the BB arrow in (a) figure. FIG. 4B illustrates a case where the left two cutters 15 are set as a left set cutter 15L, and the right two cutters 15 are set as a right set cutter 15R. 3 is conveyed toward the downstream side at the position in the width direction corresponding to each of the left cutter 15L and the right cutter 15R.

In addition, the four weighing conveyors 25, like the cutter 15, combine the two left and right, respectively, to measure the corresponding food dough 3, and the sum of the measured values of the two weighing conveyors 25 combined is When the set value is reached, each control actuator 19 is driven based on a drive command from the control device 12. In this case, each set of control actuators 19 corresponding to each of the

set cutters

15L and 15R is driven in synchronism, and the two cutters 15 forming the set are reciprocated integrally to each food dough 3. The food dough piece 7 is cut from

Furthermore, other combination drive modes will be described. FIG. 5 is an explanatory view schematically showing a combination drive mode in which the four cutters 15 are combined as one set and reciprocally moved together. FIG. 5A schematically shows the food cutting device 1. FIG. 2B is an explanatory diagram of a main part taken along line CC in FIG. This explains the case of cutting a wide row of food dough 3 with the four cutters 15.

The four weighing conveyors 25 respectively weigh the food dough 3, and when the sum of the weighing values of the four weighing conveyors 25 reaches a set value, the control actuators 19 are controlled by the control device 12. It is driven based on the drive command. In this case, the four control actuators 19 are driven synchronously, and the four cutters 15 are integrally reciprocated to cut the food dough pieces 7 from the food dough 3.

The control device 12 is provided with drive selection means 29 capable of selecting such a single drive mode and a combination drive mode. Furthermore, a plurality of the combination drive modes can be provided. The drive selection means 29 selects each mode preset in the control device 12 with a selection button displayed on the screen like a touch panel, or selects a combination from a plurality of cutter units 9 on an input screen such as a computer. It is also possible to do. Further, a sensor such as an image camera is provided above the carry-in conveyor 5 to detect the number of rows, width, and conveyance position of the food dough 3 to be conveyed, and to drive the cutter unit 9 in combination based on the information. Is also possible.

Thus, when the food dough 3 having a different number of rows is conveyed, cut, and separated by the food cutting device 1, the control device 12 includes the drive selection means 29, so that the cutter 9 need not be replaced. It can be. The drive selection means 29 may be provided in a control device such as a computer for controlling the production line including the food cutting device 1, and a setting program for each production item set in advance in the production line. It can also be included.

Although the adjacent cutter 15 is provided with a minute gap, the food dough piece 7 is cut from the food dough 3 even though the gap exists. When the cutter 15 that reciprocates integrally cuts into the food dough 3, the thin food dough 3 entering the gap is pulled by the food dough 3 pushed from above by the cutter 15 and is torn off.

The description of the food cutting device 1 based on the first embodiment of the present invention is generally as described above, but various modifications can be made within the scope of the claims. For example, the three cutter units 9 are used, the food dough 3 having a narrow width in one row is cut by one cutter unit 9 at one end, and the remaining two cutter units 9 are combined cutter units. It is also possible to cut wide food dough 3 in one row. In this way, using three or more cutter units 9, two or more kinds of food doughs 3 are simultaneously flowed to the food cutting device 1 to simultaneously obtain food dough pieces 7 having different widths and / or weights. It becomes possible.

Further, it is also possible to provide a combination drive mode in which the cutter unit 9 is provided with an even number of four or more, and a combination of two adjacent ones. It is also possible to provide a combination drive mode including three or more control actuators and a combination of two or more combinations along the width direction.

The food dough cutting apparatus 1 has been described as including the weighing conveyor 25 in order to cut and separate the food dough piece 7 with a required weight. For example, the food dough 7 has a required length. In the case of cutting, it is not necessary to provide the weighing conveyor 25, and the carry-out conveyor 11 may be arranged close to the downstream side of the carry-in conveyor 5. Moreover, the carry-in conveyor 5 and the carry-out conveyor 11 may be comprised integrally. In addition, the food dough piece 7 may be received by another device immediately after cutting without being provided with a carry-out conveyor, and may be conveyed manually or stored in a container.

Further, the carry-out conveyor 11 is arranged downstream of the front end portion of the carry-in conveyor 5 so that the rear end portion of the carry-out conveyor 11 has a drop, and the cutter 15 can be reciprocated in the horizontal direction. The cutting edge 16 of the cutter 15 may be brought into contact with the tip of the carry-in conveyor 5 to cut and separate the required food dough piece 7 from the food dough 3.
