Description

  The present invention relates to a covering / cutting device for covering and cutting food using a plurality of shutter pieces and a size checking device for the shutter pieces.

  2. Description of the Related Art Conventionally, encapsulated foods that are formed by wrapping an inner material such as candy with an outer skin material have been manufactured. As a device for molding encapsulated foods, a plurality of shutter pieces can be opened and closed with a molded body continuously formed into a rod shape by sticking the outer shell material into a cylindrical shape by closely contacting the periphery of the inner material that is continuously ejected into a rod shape. An enveloping / cutting apparatus for forming encapsulated foods by dividing and molding using the above has been developed.

  In such a covering and cutting apparatus, when the cutting area surrounded by the plurality of shutter pieces is opened and closed, the shutter pieces are opened and closed while being in sliding contact with each other, so that the sliding portions of the shutter pieces are easily worn. In particular, when the food to be cut contains granular materials such as sugar or nuts or solids such as beef streaks, the shutter member of the shutter piece is made of a resin material. As the shutter member wears, a gap is formed between the shutter pieces. If a gap is formed between the shutter pieces, there is a problem that when the food is cut, the food remains in the gap and the residue adheres to the molded product that is divided and molded, resulting in poor finish.

In order to deal with such problems, for example, in Patent Document 1, a shutter body is attached to a holder having an outer peripheral surface that is eccentric with respect to the rotation axis, and the rotation axis is appropriately rotated by a predetermined angle and attached to the holder. A shutter position correcting mechanism for adjusting the position of the shutter body with respect to the above is described. Patent Document 2 describes a shutter positioning device in which a shutter portion and a holder portion are attached to each other by at least two eccentric shafts, and the eccentric shaft is provided in a direction perpendicular to the rotation shaft of the shutter body. Yes. Further, in Patent Document 3, the shutter members adjacent to each other are combined so as to slide while maintaining a state in which the shutter members are in sliding contact with the coupling member fitted in the groove provided in the shutter piece, and the sliding of the adjacent shutter is performed. An enveloping / cutting device provided so as to be able to adjust the gap between the surfaces is described.
Japanese Patent No. 2540446 Japanese Patent No. 28877780 Japanese Patent No. 3377964

  In the devices described in Patent Documents 1 and 2 described above, the position of the shutter piece can be adjusted, but only a minute correction can be made, and it is not possible to sufficiently cope with the large wear caused by long-term use. Further, in Patent Document 3, since the coupling member and the adjustment member are inserted and attached in the groove formed in the shutter piece, it is necessary to attach these members so that they do not rattle. Therefore, it is inevitable that the adjustment accuracy will deteriorate while the adjustment work is repeated.

  Accordingly, an object of the present invention is to provide a covering and cutting apparatus capable of adjusting the position of a shutter piece so as to be reset to the same level as when it is new with respect to the wear of the shutter piece. To do. It is another object of the present invention to provide a dimension checking apparatus that can easily and accurately adjust the position of a shutter piece with respect to the wear state.

The enveloping / cutting device according to the present invention forms a cutting region surrounded by a shutter member by bringing a plurality of shutter pieces each having a shutter member into contact with each other at a sliding surface of the shutter member, and each of the shutter pieces has a rotation shaft. In the enveloping / cutting apparatus that encloses and cuts the food that passes through the cutting area by closing the tip of the shutter member so as to gather at the center of the cutting area, the shutter piece is attached to the rotating shaft. a pedestal portion which is detachably mounted, wherein the position adjusting section which performs movably mounted in alignment to abut the leading end portion of the shutter member at the center of the cutting area to the base portion to fix the shutter member It is characterized by having. Furthermore, the position adjusting unit includes an adjusting screw for adjusting the position of the tip of the shutter member. Furthermore, the position adjusting unit includes a guide unit that fixes the shutter member and is movably mounted on the pedestal unit and moves the shutter member in the direction of the distal end thereof .

A size check device for a shutter piece according to the present invention is a size check device for checking the distance from the rotation center of the shutter piece to the tip of the shutter member of the shutter piece, and mounting and fixing the pedestal portion. And a contact portion fixed to the base and formed with a reference surface for setting a reference position of a tip portion of the shutter member.

  By having the above configuration, the position of the tip of the shutter member can be adjusted by the position adjusting unit to which the shutter member is fixed. It becomes possible to reset to the same level as when.

  In addition, it is possible to easily check the size of the worn state by mounting the shutter piece on the base of the dimension checking device and determining whether the tip of the shutter piece comes into contact with the contact portion. Then, after adjusting the position of the shutter piece in the state of being attached to the dimension checking device, if the shutter piece is attached to the enveloping / cutting device, it is necessary to perform the position adjustment work with the shutter piece being attached to the enveloping / cutting device. Thus, the accurate position adjustment operation of the shutter piece can be performed easily and quickly.

  Hereinafter, embodiments according to the present invention will be described in detail. Note that the embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms.

  FIG. 1 is a front view of an embodiment according to the present invention. The enveloping / cutting apparatus includes a supply unit 1 for supplying two kinds of food materials to be used as an inner material and an outer skin material, a rod-shaped molding portion 2 for continuously molding a rod-shaped body in which the inner material is wrapped with an outer skin material, and a continuously molded rod-shaped body. A shutter part 3 for cutting and encapsulating and a support part 4 for supporting a molded product are provided.

  The supply unit 1 feeds two kinds of food into the hoppers 10 and 12, respectively, and feeds them by a screw (not shown) in the hopper. A food material G (for example, straw, jam, minced meat) fed from the hopper 10 is pumped to the rod-shaped forming portion 2 by the vane pump 11. In addition, a food material F (for example, dough using straw or flour) fed from the hopper 12 is pumped to the rod-shaped molding unit 2 by the vane pump 13.

  In addition, what is necessary is just to add and supply a hopper and a vane pump, when supplying three or more types of foodstuffs. In that case, two types of inner materials are supplied.

  The rod-shaped forming unit 2 includes a nozzle 20 that continuously discharges the foods F and G. The nozzle 20 is configured as a double nozzle. The food material G is continuously discharged from the inner nozzle and the food material F is continuously discharged from the outer nozzle, so that the food material F that is the outer skin material covers the periphery of the food material G that is the inner material. Thus, it is continuously formed into a rod shape. When two or more types of inner materials are supplied, the nozzles 20 may be multiplexed to continuously discharge the inner materials in multiple layers.

  The shutter unit 3 includes a plurality of shutter pieces 30 for covering and cutting a continuously formed rod-shaped molded body. FIG. 2 is a plan view of the shutter unit 3. FIG. 2A shows a state where the shutter piece 30 is rotated in the opening direction, and FIG. 2B is a state where the shutter piece 30 is rotated in the closing direction. Indicates the state. In this example, six shutter pieces 30 are arranged at equal intervals, and each is detachably attached to a rotation shaft (not shown). The shutter member 31 of each shutter piece 30 is fixed to the guide portion 32, and the distal end portion 31b of the shutter member 31 adjacent to the sliding contact surface 31a formed on the side portion of the shutter member 31 slides closely. Is set to

  A region S surrounded by each shutter piece 30 is a cutting region. After the continuously formed rod-shaped molded body hangs down from above and passes through the cutting region, each shutter piece 30 is rotated to close the tip 31b so as to gather at the center of the cutting region while sliding on the sliding contact surface 31a. By performing the operation, the rod-shaped molded body is encased and cut.

  FIG. 3 is a plan view (FIG. 3A) and an AA cross-sectional view (FIG. 3B) regarding the shutter piece 30. FIG. The guide portion 32 to which the shutter member 31 is fixed is mounted on the pedestal portion 33 and is set so as to be movable in the direction of the distal end portion 31b. The guide portion 32 is a metal member in which a cylindrical outer tube portion 32a and a bottom surface portion 32b are integrally formed, and the outer tube portion 32a is fitted into a mounting hole portion 31d formed in the base portion 31c of the shutter member 31. Thus, the shutter member 31 is fixed.

  The pedestal portion 33 is formed in a disc shape whose outer diameter is slightly smaller than that of the guide portion 32. Therefore, when the center positions of the guide portion 32 and the pedestal portion 33 are matched in plan view, a gap t is generated between the mounting hole portion 31 d of the shutter member 31 and the outer peripheral surface of the pedestal portion 33.

  4 is an external perspective view showing a state where the guide portion 32 is mounted on the pedestal portion 33, and FIG. 5 is an exploded perspective view thereof.

  On the lower surface of the pedestal 33, a fitting recess 33a for detachably mounting the pedestal 33 on a mounting base (not shown) is formed. A pivot shaft (not shown) is provided at the center of the pedestal 33. A shaft hole 33b for shaft mounting is formed. By mounting and fixing the shaft hole 33b of the pedestal portion 33 on the rotation shaft, the pedestal portion 33 rotates together with the rotation shaft.

  A rail portion 33e having a predetermined width is formed on the upper surface of the pedestal portion 33 toward the tip portion 31b of the shutter member 31, and a groove portion 32e having a predetermined width is formed on the lower surface of the guide portion 32 so as to face the rail portion 33e. Is formed. The groove portion 32e of the guide portion 32 is fitted to the rail portion 33e of the pedestal portion 33, and the guide portion 32 is mounted so as to be movable in the direction of the distal end portion 31b of the shutter member 31.

  As described above, since the gap t is formed around the pedestal 33 and the shutter member 31, the guide part 32 can move relative to the pedestal 33 by the distance of the gap t. Therefore, the shutter member 31 fixed to the guide portion 32 can move back and forth in the direction of the distal end portion 31b.

  An adjustment long hole 32c is formed in the bottom surface part 32b of the guide part 32 along the moving direction, and a support base 33c erected from the rail part 33e of the pedestal part 33 is fitted into the adjustment long hole 32c. Projecting into the guide portion 32.

  A support hole 33f for mounting the adjustment screw 34 is formed in the support base 33c, and the adjustment screw 34 that is mounted through the support hole 33f is supported along the moving direction of the guide portion 32. And is screwed into a screw hole 32d formed in the outer cylinder portion 32a of the guide portion 32. The adjusting screw 34 is screwed with a retaining nut 35 so as to sandwich the support base 33c, and is set so that the adjusting screw 34 does not move in the axial direction.

  Therefore, when the adjustment screw 34 is screwed into the screw hole 32d, the guide portion 32 is moved in the direction opposite to the tip portion 31b of the shutter member 31. Conversely, when the adjustment screw 34 is screwed out from the screw hole 32d, the guide portion 32 acts to move in the direction toward the distal end portion 32d. By operating the adjustment screw 34 in this way, the position of the guide portion 32 can be adjusted.

  A fixing screw 36 is inserted into the adjustment long hole 32 c of the guide portion 32 and is screwed into a screw hole 33 d formed in the upper surface of the pedestal portion 33. The guide portion 32 can be fixed to the pedestal portion 33 by tightening and fixing the fixing screw 36. Therefore, the fixing screw 36 is loosened, the adjusting screw 34 is operated to adjust the position of the guide portion 32, and the fixing screw 36 is fastened and fixed, thereby enabling easy and accurate positioning and fixing.

  In this example, as the position adjusting unit, the shutter member 31 is fixed and the guide unit 32 movably mounted on the pedestal unit 33 and the guide unit 32 are moved to adjust the position of the tip 31b of the shutter member 31. A screw 34 is provided. In addition, as a moving mechanism of the guide part 32, you may use things other than the screw for adjustment (for example, well-known mechanisms, such as a cam mechanism), and it is not specifically limited.

  The support unit 4 moves up and down the cradle 40 via the cradle 40 disposed below the shutter unit 3, a support rod 41 that is fixed to the lower surface of the cradle 40 and supports the cradle 40, and the support rod 41. A cam drive mechanism 42 is provided, and a conveyor belt 44 of a belt conveyor 43 is set on the upper surface of the cradle 40. Then, the molded product that is encased and cut by raising the cradle 40 is supported from below and placed on the conveyor belt 44, and the molded product obtained by molding by lowering the cradle 40 is used as it is. It is transported by the transport belt 44.

  6 to 9 are explanatory diagrams relating to a process of covering and cutting the rod-shaped molded body with the shutter piece 30. In FIG. 6, a rod-shaped molded body that is set in a state where the shutter piece 30 is rotated counterclockwise and opened, and the outer skin material F is continuously discharged from the nozzle 20 so as to cover the inner material G. Hangs downward and passes through a cutting area surrounded by each shutter piece 30.

  When the rod-shaped body passes through the cutting region by a predetermined length, as shown in FIG. 7, each shutter piece 30 rotates clockwise, and the cutting region is closed. And it reaches | attains to the position where the slidable contact surface 31a of each shutter piece 30 contacts a rod-shaped molded object. As each shutter piece 30 is further rotated clockwise, the sliding contact surface 31a of each shutter piece 30 operates in a direction to close while sliding the outer periphery of the rod-shaped molded body, and as shown in FIG. The contact surface 31a hits and the rod-shaped molded body is cut. Then, by further rotating each shutter piece 30 clockwise, as shown in FIG. 9, the distal end portion 31b of each shutter piece 30 abuts and the outer shell material F of the rod-shaped molded body is gathered together, and the inner material G The covering and cutting operation for covering the surface with the outer skin material F is performed reliably.

  As described above, the tip end portion 31b of the shutter piece 30 is always in sliding contact with the adjacent shutter piece in the covering and cutting operation, and thus wears as the operation is repeated. In particular, if the food material contains hard granular materials (sugar, nuts, etc.), wear tends to proceed.

  When the tip portion 31b is worn, a gap is formed between the tip 31b and the sliding contact surface 31a, or a gap is formed when the tip portions 31 abut each other. Ingredients remain in the gaps formed in this way, and the covering and cutting operation is incomplete, and the finished product is deteriorated. Therefore, it is necessary to adjust the position of the shutter piece so that no gap is generated according to the degree of wear of the tip 31b.

  As described above, the shutter piece 30 is provided with a function for adjusting the position of the shutter member 31, and by operating the adjustment screw 34, the shutter member 31 is moved toward the tip 31b to adjust the position. Can do. However, it is difficult to adjust the position so that each tip 31b abuts exactly at one point as shown in FIG. 9 with a plurality of shutter pieces 30 mounted. Therefore, in this embodiment, a dimension checking device is used that can individually check the wear state of the shutter piece 30 and adjust the position of the shutter piece 30 to the same level as when it is new.

  FIG. 10 is an external perspective view of the dimension confirmation device 5, and FIG. 11 is a plan view (FIG. 11A) and a BB cross-sectional view (FIG. 11) showing a state where the shutter piece 30 is attached to the dimension confirmation device 5. 11 (b)). The size checking device 5 includes a contact portion 51 that checks the wear state of the base 50 on which the shutter piece 30 is mounted and the tip end portion 31b of the shutter member 31 and adjusts the reference position to the same level as when it is new. Yes.

  The base 50 is made of a metal rod-shaped body having a rectangular cross section, and a fitting convex portion 50a for mounting and fixing the fitting concave portion 33a of the pedestal portion 33 of the shutter piece 30 is formed on the upper surface. The contact portion 51 is fastened and fixed to one end portion of the base 50 by a fixing screw, and a pair of support plates 51b fixed to both side surfaces of the base 50 are in contact with both sides thereof so that the contact portion 51 is It is firmly fixed so that it does not move from side to side.

  An upper portion of the contact portion 51 protrudes toward the base 50 and a reference surface 51a is formed. The reference surface 51a is formed in a circular arc shape in plan view so as to coincide with the locus of rotation of the distal end portion 31b when the shutter piece 30 mounted on the base 50 rotates. The distance L from the shaft hole 33b, which is the rotation center of the shutter piece 30, to the reference surface 51a is such that the shutter member 31 of the new shutter piece 30 when the shutter piece 30 is mounted on the shutter portion of the enveloping / cutting device. The distance from the tip to the center of rotation is set.

  Therefore, it is possible to check the size of the worn state depending on how much clearance is generated between the front end portion 31b of the shutter piece 30 mounted on the base 50 and the reference surface 51a. If the position of the guide portion 32 is adjusted by operating the adjustment screw 34 so as to be moved, the position of the tip portion 31b of the shutter piece 30 can be adjusted to the same level as when it is new. Can do.

  In this case, when the adjusting screw 34 is screwed into the screw hole 32d, the guide portion 32 is moved in the direction opposite to the tip portion 31b of the shutter member 31. Conversely, when the adjustment screw 34 is screwed out from the screw hole 32d, the guide portion 32 acts to move in the direction toward the distal end portion 32d. By operating the adjustment screw 34 in this way, the position of the guide portion 32 to which the shutter member 31 is fixed can be adjusted.

  Thus, after adjusting the position of the shutter piece 30 by the dimension checking device 5, the shutter member 31 is fixed in a state where the position is adjusted by tightening and fixing the fixing screw 36. Then, by mounting the position-adjusted shutter piece 30 on the shutter portion 3, the tip portion 31b can be reliably set in the same state as when the tip portion 31b is new.

  As described above, even when the tip portion 31b of the shutter piece 30 is worn, the tip portion 31b can be easily reset to the same level as when it is new using a dimension confirmation device. Thus, it is possible to maintain an accurate covering and cutting operation over a long period of time. Further, the guide portion 32 mounted on the pedestal portion 33 of the shutter piece 30 can be designed to be movable up to several millimeters, and can sufficiently cope even when the amount of wear of the tip portion 31b becomes large. It is excellent in nature.

  In the above-described embodiment, an example using six shutter pieces has been described. However, the present invention can be applied even when a number of shutter pieces other than six is used. For example, FIG. 12 shows an open state (FIG. 12A) and a closed state (FIG. 12B) when four shutter pieces are used. Also in this case, as in the case of using six shutter pieces, the cutting region is opened and closed by the rotation of the shutter member 61 of each shutter piece 60, and the leading end of each shutter piece 60 abuts. A covering cutting operation is performed.

  FIGS. 13A and 13B are a plan view (FIG. 13A) and a CC cross-sectional view (FIG. 13B) showing a state in which the shutter piece 60 is mounted on the dimension checking device 5. FIG. The pedestal portion 63 of the shutter piece 60 is mounted on the base 50 of the dimension checking device 5, and the size of the worn state is confirmed based on whether or not there is a gap between the distal end portion 61b of the shutter member 61 and the reference surface 51a. If there is, the position of the guide member 62 is adjusted by operating the adjustment screw 64 to adjust the position so that the front end portion 61b of the shutter member 61 abuts on the reference surface 51a. By tightening and fixing the fixing screw 66 after adjusting the position of the shutter member 61, the tip of the shutter piece 60 can be reset to the same level as when it is new.

  Also in this example, as the position adjusting portion, the shutter member 61 is fixed and the guide portion 62 movably attached to the pedestal portion 63 and the guide portion 62 are moved to adjust the position of the tip portion 61b of the shutter member 61. An adjustment screw 64 is provided.

  FIG. 14 is a plan view showing a double shutter unit using two sets of four shutter pieces, FIG. 14 (a) shows an open state, and FIG. 14 (b) shows a closed state. Yes. In this example, the shutter part can simultaneously perform the covering and cutting operation by the two sets of shutter pieces.

  Two common shaft shutter pieces 70 are provided between the two sets, and the common shaft shutter piece 70 includes shutter members 71 and 72 extending in the orthogonal direction. Then, by rotating the common-shaft shutter piece 70 with one rotating shaft, the shutter members 71 and 72 can be simultaneously rotated to perform the enveloping / cutting operation, thereby simplifying the driving mechanism of the shutter piece. It becomes possible.

  The common shaft shutter piece also wears at the tip of each shutter member, so that it is necessary to adjust the position for resetting it to the same level as when it is new. FIG. 15 is a plan view (FIG. 15A), a DD sectional view (FIG. 15B), and an EE sectional view (FIG. 15C) regarding the common shaft shutter piece. The base 71c of the shutter member 71 has a lower half that is cut out and formed thin, and the base 72c of the shutter member 72 is cut out and formed in a thin thickness. Then, both shutter members are installed with the base 71c overlapped on the upper surface of the base 72c. Circular mounting holes 71b and 72b are formed in the bases 71c and 72c, respectively, and ring-shaped guide parts 74 and 75 are fitted in the mounting holes 71b and 72b, respectively.

  The guide parts 74 and 75 are arranged vertically so as to overlap each other, and a pedestal part 73 having a circular shape in plan view is fitted therein. The guide portion 74 is set so that the inner peripheral surface is formed in an elliptical shape and the direction toward the tip end portion 71 a of the shutter member 71 is a long axis. The diameter of the ellipse in the short axis direction is set to be substantially equal to the diameter of the pedestal portion 73, and the diameter in the long axis direction is set to be several mm larger than the diameter of the pedestal portion 73. It can move toward the tip 71a with respect to the portion 73.

  As with the guide portion 74, the guide portion 75 is set so that the inner peripheral surface is formed in an elliptical shape and the direction toward the distal end portion 72 a of the shutter member 72 is the long axis. The diameter of the elliptical minor axis direction is set to be substantially equal to the diameter of the pedestal portion 73, and the diameter of the major axis direction is set to be about several mm larger than the diameter of the pedestal portion 73. It can move toward the tip 72a with respect to the portion 73.

  The pedestal portion 73 is formed with a fitting recess 73a for detachably mounting the pedestal portion 73 on a mounting base (not shown), and a pivot shaft (not shown) is attached to the center position of the pedestal portion 73. A shaft hole 73b for this purpose is formed. By attaching and fixing the shaft hole 73b of the pedestal portion 73 to the rotation shaft, the pedestal portion 73 rotates together with the rotation shaft.

  As shown in FIG. 15B, an insertion hole is formed in the end of the shutter member 71 opposite to the tip 71a from the side surface toward the mounting hole 71b, and an adjustment screw is provided in the insertion hole. 76 is inserted. A retaining nut 77 is screwed to the inserted adjustment screw 76 so as to sandwich the base portion 71c, and is further screwed into a screw hole 73c formed in the base portion 73. Then, the adjustment screw 76 is screwed into the screw hole 73c, so that the shutter member 71 moves toward the distal end portion 71a, and if it is screwed out from the screw hole 73c, it moves in the opposite direction. Therefore, by operating the adjustment screw 76, the tip 71a of the shutter member 71 can be moved forward and backward to adjust the position. The shutter member 71 is positioned and fixed with respect to the pedestal portion 73 by fastening and fixing a fixing nut 78 screwed to the tip of the adjustment screw 76 after the position adjustment of the shutter member 71.

  As shown in FIG. 15 (c), an insertion hole is formed in the end of the shutter member 72 opposite to the tip 72a from the side surface toward the mounting hole 72b, and an adjustment screw is provided in the insertion hole. 79 is inserted. The tip end of the adjustment screw 79 is screwed into a screw hole 73 d formed in the pedestal portion 73. Then, the adjustment screw 79 is screwed into the screw hole 73d, so that the shutter member 72 moves toward the distal end portion 72a, and if it is screwed out from the screw hole 73d, it moves in the opposite direction. Therefore, by operating the adjustment screw 79, the tip 72a of the shutter member 72 can be moved back and forth to adjust the position.

  A fixing screw 80 is screwed onto the pedestal portion 73 in a direction orthogonal to the adjustment screw 79, and the tip of the fixing screw 80 is pressed against the tip of the adjustment screw 79 after the position adjustment of the shutter member 72. The fixing screw 80 is operated as described above. The adjustment screw 79 to which the tip of the fixing screw 80 is pressed is fixed in a position-adjusted state, and the shutter member 72 is positioned and fixed with respect to the pedestal portion 73.

  In the position adjustment of the shutter members 71 and 72 described above, the respective shutter members are sequentially inserted into the above-described dimension confirmation device 5 and the dimensions of the wear state are confirmed, and then the tip of each shutter member is in contact with the reference surface 51a. By adjusting the position so as to be, it is possible to easily and accurately reset the state to the same level as when it is new.

  FIG. 16 is a plan view showing a double shutter unit using two sets of six shutter pieces, FIG. 16 (a) shows an open state, and FIG. 16 (b) shows a closed state. Yes. In this example as well, as in the example shown in FIG. 14, the shutter section can simultaneously perform the covering and cutting operation by the two sets of shutter pieces.

  Two common-shaft shutter pieces 80 are provided between the two sets, and the common-shaft shutter piece 80 is provided with shutter members 81 and 82 extending in the opening direction at an angle of 120 degrees. Then, by rotating the common-shaft shutter piece 80 with one rotating shaft, the shutter members 81 and 82 can be simultaneously rotated to perform the covering and cutting operation, thereby simplifying the driving mechanism of the shutter piece. It becomes possible.

  Even in this example, the same pedestal portion 83 and guide portion 84 as in the example shown in FIG. 14 are provided, and the position of the shutter member 81 can be adjusted in the same manner as the shutter member 71. Further, the shutter member 82 can be adjusted in the same position as the shutter member 72 by using the guide portion and the pedestal portion 83 provided below the guide portion 84. Then, the shutter members 81 and 82 are sequentially mounted on the dimension confirmation device 5 to confirm the dimension in the worn state, and the tip of the shutter member can be reset to the same level as when it is new with the adjusting screw.

  As explained above, even if the tip of the shutter piece is worn by attaching the guide part and the base part to various types of shutter parts and operating the adjustment screw, the state is as easy and accurate as when it is new Can be reset to In the above example, the example of using 6 sheets and 4 sheets has been described, but the present invention can also be applied to the case of using other numbers of shutter pieces. Further, the present invention can be applied to a multiple shutter type other than the double type, and is not particularly limited.
