Japanese Patent No. 3016246 Japanese Patent No. 3688254 Japanese Patent No. 5002231

Patent Document 1 includes a shutter piece that can move along a swing guide portion provided on each rotation shaft arranged at a regular polygonal position, and molding the tip end side of each shutter piece with an adjacent shutter piece. Described is a shutter device that is provided in sliding contact with a surface and is provided with a polygonal opening surrounded by a molding surface in each shutter piece so as to be openable and closable.

In the configuration described in Patent Document 1, although the shutter pieces adjacent to each other are slidably connected by the coupling member, there is a minute gap in the sliding contact portion between the shutter pieces adjacent to each other and the molding surface. For example, a very small part of food dough such as fine bones such as fish meal may enter and wear each shutter piece.

Therefore, as described in Patent Document 2, a configuration has been proposed in which an eccentric pin is provided on the tip end side of the shutter piece to adjust a minute gap on the tip end side of each shutter piece.

Further, as described in Patent Document 3, an endless elastic member is hung around the outer end of each shutter piece so that adjacent shutter pieces are always held in a pressing contact state to perform an opening / closing operation. Is described. According to the configuration described in Patent Document 3, the forming surface and the sliding surface of the adjacent shutter pieces are urged so as to be in constant contact with each other by the urging force of the elastic member. Therefore, it is desirable to suppress the formation of minute gaps on the contact surfaces of the shutter pieces adjacent to each other.

However, in the configuration described in Patent Document 3, each shutter piece that is slidable along the sliding portion provided on the rotating shaft is in a form of being stretched parallel to the sliding direction. When the central opening of the polygon surrounded by the molding surface of each shutter piece is large (see, for example, FIGS. 3 and 4 of Patent Document 3), the adjacent shutter pieces act on the shutter pieces by the urging force of the elastic member. The moment of pressing contact with the molding surface of the above is relatively large. However, as the opening becomes smaller and smaller (see FIGS. 5 and 6 of the same), the moment of pressing contact with the molding surface of the adjacent shutter piece becomes smaller and smaller.

Therefore, in the configuration described in Patent Document 3, when the opening becomes smaller, the contact portion in the adjacent shutter piece may open slightly. Then, a part of the food dough may enter into this slightly opened gap. Therefore, improvement of the shutter device has been desired.

The present invention has been made in view of the above-mentioned problems, and is provided with a shutter piece that can move along a swing guide portion provided for each rotation shaft arranged at a regular polygonal position, and the shutter piece of each shutter piece.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. By the way, the overall configuration of the package cutting device is a well-known configuration as described in Patent Documents 1, 2 and 3. Therefore, the description of the overall configuration of the encapsulation cutting device will be omitted, and the configuration of the main part will be described.

With reference to FIG. 1, the shutter device 1 according to the embodiment of the present invention includes each rotation shaft 3 arranged at a regular polygonal position. In the rotation shaft 3, one rotation shaft is interlocked and connected to an appropriate rotation actuator (not shown) in the same manner as in the configurations described in Patent Documents 1 to 3. The rotating shafts 3 are interlocked and connected so as to rotate in the same direction at the same time. Since the rotating shafts 3 may be interlocked with each other, the description of the interlocking configuration will be omitted.

A swing guide portion 5 that is long in a direction orthogonal to the longitudinal direction of the rotation shaft 3 is integrally provided on the upper portion of the rotation shaft 3. The swing guide portion 5 is slidably provided with a stretched portion main body 9 of the shutter piece 7. That is, the stretched portion main body 9 includes a molding surface 13 that forms a polygonal opening 11 for covering and cutting the food dough. An opposing surface 15 facing the molding surface 13 of the adjacent shutter piece 7 is formed on the tip end side of the stretched portion main body 9. The facing surface 15 is inclined so as to form an acute angle with the molding surface 13 of the shutter piece 7.

The stretched portion main body 9 is stretched in a direction parallel to the longitudinal direction of the molding surface 13. An elongated hole 17 parallel to the stretching direction (longitudinal direction of the molding surface 13) is formed in the stretched portion main body 9. The guide surface 5G of the swing guide portion 5 is slidably engaged in the elongated hole 17. In other words, the swing guide portion 5 is fitted in the elongated hole 17 so as to be relatively movable.

The stretched portion main body 9 of the shutter piece 7 is provided with a ridge sliding portion 19 parallel to the longitudinal direction of the molding surface 13. A restraint sliding member 21 provided on the tip end side of the extension portion main body 9 of the adjacent shutter piece 7 is slidably engaged with the sliding portion 19. The restraint sliding member 21 has a function of restricting the separation between the molding surface 13 and the facing surface 15 of the adjacent shutter pieces 7.

The restraint sliding member 21 is configured so that the minute position can be adjusted to adjust the minute gap between the molding surface 13 and the facing surface 15 in the adjacent shutter piece 7. That is, the restraint sliding member 21 is provided with an eccentric pin 23 similar to the eccentric pin described in Patent Document 2. The configuration for adjusting the position of the restraint sliding member 21 by the eccentric pin 23 is a already known configuration as described in Patent Document 2. Therefore, detailed description of the configuration for adjusting the position of the restraint sliding member 21 by the eccentric pin 23 will be omitted.

An elastic member 25 such as an endless O-ring is hung on each shutter piece 7 in order to press and urge the facing surface 15 of each shutter piece 7 against the molding surface 13 of each adjacent shutter piece 7. A hanging portion 27 for turning is provided so as to bend and project in the longitudinal direction. A groove 27G for hooking the elastic member 25 is formed on the outer periphery of the protruding portion of the hooking portion 27. The hanging portion 27 is provided on the base end side of the stretched portion main body 9 of the shutter piece 7.

More specifically, the hanging portion 27 is on the opposite side (base end portion side) of the facing surface 15 provided on the tip end side in the longitudinal direction (direction parallel to the longitudinal direction of the elongated hole 17) of the extension portion main body 9. Therefore, it is provided so as to bend and project in the direction opposite to the molding surface 13. In other words, the shutter piece 7 is provided with the hooking portion 27 bent and projected from the base end portion of the extension portion main body 9, so that the overall configuration of the shutter piece 7 is substantially L-shaped.

With the above configuration, as shown in FIG. 1, when the opening 11 is wide open, the straight line L1 connecting the center O of the opening 11 and the center P of the rotation shaft 3 and the center P of the rotation shaft 3 The straight line L2 connecting the hooked portion 27 with the vicinity of the protruding end Q of the portion where the elastic member 25 is hooked is substantially a straight line. Therefore, the rotational force for rotating each shutter piece 7 in order to reduce the opening 11 due to the urging force that the elastic member 25 tends to shrink is small.

Then, as shown in FIGS. 2 to 4, as the opening 11 becomes smaller, the angle formed by the straight line L1 and the straight line L2 gradually becomes smaller. In other words, due to the urging force of the elastic member 25, the rotational force for rotating each shutter piece 7 in the direction of reducing the opening 11 around the rotation shaft 3 gradually increases. Therefore, the pressing force that the molding surface 13 of the shutter piece 7 presses against the facing surface 15 of the adjacent shutter piece 7 gradually increases as the opening 11 becomes smaller.

Therefore, it is possible to effectively prevent the gap between the molding surface 13 and the facing surface 15 of the adjacent shutter pieces 7 from becoming large.

With reference to FIGS. 5 and 6, the facing surface 15 facing the molding surface 13 of the stretched portion main body 9 of the adjacent shutter piece 7 is formed on the tip end side of the stretched portion main body 9 of the shutter piece 7. The tip of the stretched portion main body 9 of the shutter piece 7 where the molding surface 13 and the facing surface 15 intersect is provided with a protruding portion 29 that protrudes in a bent form with respect to the facing surface 15.

The end faces 29A to 29F of the protruding portion 29 are formed on the sliding contact surface that is in sliding contact with the molding surface 13 of the adjacent shutter piece 7. The sliding contact surface 29D is formed by forming an engaging recess 31 between the sliding contact surface 29C and the sliding contact surface 29E. The bottom of the engaging recess 31, that is, the sliding contact surface 29D, is formed in the same plane as the facing surface 15 (in FIG. 5, it is displayed by cross-hatching to show that they are in the same plane. is there).

The shape of the molding surface 13 is formed so as to be in sliding contact with the sliding contact surfaces 29A to 29F of the adjacent shutter piece 7. Therefore, a ridge 33 that slidably engages with the engaging recess 31 is provided at the center of the molding surface 13 in the width direction.

According to the above configuration, when the shutter pieces 7 are combined as shown in FIG. 1, the molding surface 13 of the adjacent shutter pieces 7 and the tip surfaces (sliding contact surfaces) 29A to 29F of the protruding portion 29 of the shutter piece 7 are formed. It will come into surface contact. At this time, since the sliding contact surface 29D is formed on the same plane as the facing surface 15, the ridges 33 provided on the adjacent shutter pieces 7 face each other on the sliding contact surface 29D and the extension line of the sliding contact surface 29D. It will come into surface contact with the surface 15.

Therefore, in the shutter piece 7, the end faces 29A to 29F of the protruding portion 29 and the portion sliding with the convex portion 33 of the adjacent shutter piece 7 are in surface contact with each other. Therefore, the surface contact portion on the facing surface 15 side has a T shape.

As can be understood from the above description, the molding surface 13 of the shutter piece 7 is in surface contact with the sliding contact surfaces 29A to 29F of the protrusion 29 of the adjacent shutter piece 7, and the convex portion provided on the molding surface 13. Reference numeral 33 denotes surface contact with the facing surface 15 on the extension of the sliding contact surface 29D and the sliding contact surface 29D. Then, due to the presence of the ridge portion 33, an appropriate gap is maintained between the molding surface 13 and the facing surface 15 without any surface contact.

Therefore, the wear of the tip portion is suppressed as compared with the case where the tip end portion of the facing surface 15 is in line contact with the molding surface 13. Further, the convex portion 33 of the shutter piece 7 engages with the engaging recess 31 formed on the tip surface of the adjacent shutter piece 7, and the facing surface 15 extends over a long range on the extension line of the engaging recess 31. Are in contact with. Therefore, it is possible to prevent the adjacent shutter pieces 7 from slightly moving in the axial direction of the opening 11. Therefore, the opening / closing operation of each shutter piece 7 can be smoothly performed.

Further, as described above, when the opening 11 becomes smaller, the pressing force for pressing the molding surface 13 of the shutter piece 7 toward the facing surface 15 side of the adjacent shutter piece 7 becomes stronger. In addition, the contact between the molding surface 13 and the facing surface 15 is a surface contact on the end faces 29A to 29F of the protruding portion 29. Therefore, it is possible to prevent a very small part of the food dough from entering the minute gap between the molding surface 13 and the facing surface 15 of the adjacent shutter pieces 7.

9 to 11 show the shutter piece 7A according to the second embodiment of the present invention. In the shutter piece 7A, the same reference numerals are given to the components having the same functions as the components of the shutter piece 7 described above, and the duplicate description will be omitted.

In the shutter piece 7A according to the second embodiment, the sliding contact surfaces similar to the sliding contact surfaces 29A to 29F in the shutter piece 7 described above (since the functions are the same, the reference numerals are shown to be the same) are opposed to each other. It is provided on the tip side of the surface 15. The angle θ1 (see FIG. 10) between the sliding contact surfaces 29A to 29F and the molding surface 13 is the extension surface 29A1 to 29F1 of the sliding contact surfaces 29A to 29F formed on the facing surface 15 and the molding surface 13. It is formed at an angle slightly larger than the angle θ2 between them.

Therefore, in the shutter piece 7A, the sliding contact surfaces 29A to 29F are in surface contact with the molding surface 13 of the adjacent shutter piece 7A and slide. Then, there is a slight gap between the extension surfaces 29A1 to 29F1 and the molding surface 13 of the adjacent shutter piece 7A. Therefore, the surface pressure of the end faces 29A to 29F in the protruding portion 29 becomes larger. Therefore, it is possible to more effectively prevent a part of the food dough from entering between the molding surface 13 and the facing surface of the adjacent shutter piece 7A.

FIG. 12 shows the shutter piece 7B according to the third embodiment of the present invention. In the shutter piece 7B, the components having the same functions as the components of the shutter piece 7 described above are designated by the same reference numerals, and the duplicate description will be omitted.

In the shutter piece 7B, the configuration of the engaging recess 31 formed in the protruding portion 29 is different from the configuration of the shutter piece 7. That is, the bottom portion of the engaging recess 31 in the shutter piece 7, that is, the sliding contact surface 29D is formed in the same plane as the facing surface 15. However, in the present embodiment, the sliding contact surface 29D in the engaging recess 31 is formed slightly higher than the plane surface of the facing surface 15.

Therefore, the ridge 33 provided on the adjacent shutter piece 7B is held in a state slightly separated from the facing surface 15. Therefore, similarly to the shutter piece 7A described above, the surface pressure of the end faces 29A to 29F in the protruding portion 29 becomes larger. Therefore, the shutter piece 7B also has the same effect as the shutter piece 7A described above. Further, the facing surface 15 of the shutter piece 7B is flat, which has an advantage that processing is easy.
