Description

  The present invention relates to a food cutting device that cuts rod-shaped foods such as sushi rolls into a predetermined width in a round shape, and in particular, tension adjustment of the cutting blade in a food cutting device that supports the cutting blade in a double-ended manner It has features in the mechanism.

  For example, sushi rolls provided at supermarkets, convenience stores, carousel sushi restaurants, etc. are formed into sticks by an automatic machine, and are further cut into round shapes to a predetermined width. If a stick-shaped sushi roll is manually cut into round pieces with a knife, it takes a lot of labor and time, and the width of the round pieces varies, so a food cutting device is used. There exist some which cut a food cutting device by moving a cutting blade with respect to the fixed cutting blade, and what cuts by moving a cutting target food with respect to the fixed cutting blade. Moreover, according to the support form of a cutting blade, it can classify | categorize into the thing of a cantilever type and the thing of a both-ends type.

  According to the food cutting apparatus that moves the cutting blade with respect to the fixed food to be cut and cuts it, the set position of the food to be cut and the take-out position of the cut food are the same, and the workability is good. However, since the rotary blade crosses the food to be cut placed on the mounting table, a safety mechanism is provided to ensure safety when the rotary blade crosses the food to be cut so that a hand cannot be inserted around the mounting table. It is necessary to secure. In addition, since the cutting blade is cantilevered to the rotating shaft, it is necessary to increase the thickness of the blade to give it a predetermined strength. Is slightly inferior. Therefore, in the case of a soft food to be cut such as seaweed roll sushi, it is desirable to use a double-sided cutting blade that is not easily deformed by the pressure applied during cutting.

  Patent Document 1 describes a cutting device for seaweed roll sushi or the like that cuts seaweed roll sushi or the like into a slice by moving the cutting blade against the seaweed roll sushi or the like that is a fixed food to be cut. The cutting blades are arranged parallel to the blade frame and held at both ends in the length direction, i.e., are both supported.The blade frame is moved with a plurality of cutting blades by a link mechanism to cut nori sushi rolls, etc. It is configured to do.

  Patent Document 2 describes a rolled sushi cutting device that moves and cuts rolled sushi, which is a food to be cut, with respect to a fixed cutting blade. The cutting blade is a plurality of cutting blades arranged in parallel to the blade frame and held at both ends in the length direction, that is, a both-end supported shape, and the blade frame is fixed to the frame. The above-mentioned rolled sushi is placed on a cradle, and this cradle is moved from the bottom to the top, so that the sushi roll is cut into round slices while gradually engulfing the cutting blade into the sushi roll. . A food cutting device that cuts a target food in a circular shape by fixing the cutting blade and moving the target food relative to the cutting blade is also described in Patent Document 3.

  Even if the cutting blade is a movable blade like the cutting device described in Patent Document 1 or a fixed blade like the invention described in Patent Document 2 and Patent Document 3, a plurality of rectangular blades The cutting blades are passed in parallel, and both end portions of each cutting blade are of a double-supported type fixed to the frame body. The both-end-type cutting blade needs to be given an appropriate tension so as to withstand the pressure applied when the target food comes into contact. Therefore, as described in Patent Documents 1 to 3, a tension adjusting structure is provided for each cutting blade on the frame body so as to individually adjust the tension of each cutting blade.

JP-A-7-31392 Japanese Patent No. 4368024 JP 2006-68848 A

  The cutting blade provided in the food cutting device is a kind of consumable, and needs to be replaced every certain number of times. However, according to the conventional food cutting apparatus provided with the doubly-supported cutting blade having a structure as described in Patent Documents 1 to 3, the tension adjusting structure provided for each of the plurality of cutting blades allows the individual food cutting device to It is necessary to adjust the tension of the cutting blade, and it is difficult to adjust the tension of all the cutting blades in a balanced manner. Therefore, special skills are required for exchanging the cutting blade and adjusting the tension, and it is difficult for the user of the food cutting device to exchange and adjust the cutting blade. In addition, if the tension of the cutting blade is adjusted individually, the tension of each cutting blade tends to be excessive, and the tension of all the cutting blades is combined, and the frame holding the cutting blade is excessive. The frame body may be deformed during long-term use. When the frame is deformed, the tension of the cutting blade is loosened, and the food cutting performance is lowered.

  Furthermore, according to the conventional food cutting device, the tension of the cutting blade may change over time. The causes include variation in accuracy in the manufacturing process of the cutting blade, for example, variation in pitch of holes for fixing the cutting blade, shrinkage and warping of the cutting blade due to blade cutting, baking, coating, and the like. In addition, when the cutting blade is used many times, the extension of the cutting blade itself, enlargement of a hole for fixing the cutting blade, and the like also cause fluctuations in the tension of the cutting blade over time.

  The present invention eliminates the problems of the conventional food cutting apparatus described above, that is, it is easy to replace the cutting blade and adjust the tension, and even when the cutting blade is loose, the predetermined cutting blade is used for cutting food. An object of the present invention is to provide a food cutting device that can prevent the food cutting performance from being lowered due to the slack of the cutting blade.

The food cutting device according to the present invention comprises:
A food placing table for placing the food to be cut;
A cutting blade whose longitudinal ends are held by a cutting blade fixing frame;
A drive mechanism for relatively moving the food placing table and the cutting blade to cut the food to be cut in a circular shape,
The cutting blade has bosses protruding at both ends in the length direction,
The cutting blade fixing frame is provided with a cutting blade latching member having a V-shaped groove for latching the boss of the cutting blade along a pair of side edges,
At least one of the cutting blade latching members has a tension adjusting member that can adjust the tension applied to the cutting blade by adjusting the distance from the other cutting blade latching member. Main features.

  According to the food cutting device according to the present invention, when the food to be cut and the cutting blade come into contact, the boss of the cutting blade is pressed into the V-shaped groove by the pressing force applied to the cutting blade, and the inclined surface of the V-shaped groove The component force of the direction which pulls away the boss | hub of the both ends of a cutting blade mutually is produced | generated. Since this component force increases the tension of the cutting blade and generates a tension corresponding to the pressing force, there is an advantage that the necessary tension is generated when necessary even if the tension adjustment of the cutting blade is loose. There is also an advantage that the cutting blade can be easily replaced and the tension can be easily adjusted.

  Hereinafter, an embodiment of a food cutting device according to the present invention will be described with reference to the drawings. In the embodiment described below, a plurality of cutting blades are used. However, in the food cutting device according to the present invention, the number of cutting blades is arbitrary, and only one cutting blade is used. Also good.

  1 to 3, the food cutting device includes a supply unit for food to be cut (hereinafter simply referred to as “food”) at the upper end, and a food take-out unit 8 at the lower front portion. It is covered with a front panel 15 except for the take-out portion 8, and both left and right side surfaces are covered with a side cover 14. At the initial position before the operation of the apparatus is started, the food supply table 5 is provided in the supply unit, and a columnar laver roll in which food 10, for example, sushi rice is wrapped in laver, is placed on the food placement table 5 in the longitudinal direction. It is comprised so that it may mount in the attitude | position toward the horizontal direction. When the food 10 is placed on the food placing table 5 and the start switch is pressed, the food placing table 5 is moved toward the lower front side of the apparatus by a drive mechanism described in detail later. Is cut into a ring shape by a cutting blade and delivered to the take-out portion 8. The food 10 delivered from the food placing table 5 to the take-out unit 8 is received by a fixed inclined guide member 81 and a receiving member 82 which is guided by the inclined guide member 81 and moves up and down. And the food placing table 5 is configured to return to the original position by the drive mechanism.

  Next, the internal structure of the food cutting device will be described in detail. 1 to 3 and 9, the food cutting device includes a base 1, left and right side plates 4 that are coupled to both left and right ends of the base 1 and rise in a vertical direction in parallel to each other, and rear end portions of the side plates 4. The base 1, the left and right side plates 4 and the back plate form a skeleton of the food cutting device. The cutting blade fixing frame 2 (see FIGS. 2 to 5, 7, and 8) is disposed in a substantially vertical position at a position near the front of the apparatus. The cutting blade fixing frame 2 is dropped along a pair of guide rails whose left and right end edges are fixed to the left and right side plates 4 in the vertical direction, and is substantially fixed between the left and right side plates 4 by the guide rails. Has been.

  As shown in FIGS. 2 to 5 and 8, the cutting blade fixing frame 2 has a rectangular frame shape whose height is slightly lower than the height of the apparatus, and a plurality of cutting blades 3 above and below the cutting blade fixing frame 2. Both end portions in the longitudinal direction are held, and the cutting blades 3 are arranged in parallel in the vertical direction. In the illustrated example, seven cutting blades 3 are arranged at regular intervals, and the food 10 is divided into eight equal parts. Each cutting blade 3 is a thin and thin plate-like member, and is arranged so that the width direction thereof faces the front-rear direction of the apparatus and the forming edge of the blade faces the back side. The surface of each cutting blade 3 is coated with, for example, a fluororesin in order to improve the sliding with respect to the food 10. Each of the cutting blades 3 has a both-end support type in which both end portions in the length direction are held above and below the cutting blade fixing frame 2, so that a sufficiently large mechanical strength can be obtained even with a thin and thin plate-like member as described above. Can keep. A cutting blade unit 100 is constituted by the cutting blade fixing frame 2 and a plurality of cutting blades 3 held in a supported manner by the cutting blade fixing frame 2. Hereinafter, the cutting blade unit 100 will be described in detail.

  4 to 8, on the back side of the cutting blade fixing frame 2, a tension applying block 110 is provided at the upper end portion, and a tension holding plate 120 is provided at the lower end portion, respectively, and an upper girder 21 constituting the cutting blade fixing frame 2. Arranged along the lower girder 22. The tension applying block 110 and the tension holding plate 120 function as a cutting blade latching member. A tension adjusting screw 130 as a tension adjusting member is inserted from the upper side of the girder 21 at both ends in the length direction of the upper girder 21 of the cutting blade fixing frame 2, and a thread portion of each tension adjusting screw 130 of the tension applying block 110. It is screwed into the screw hole. The head of each tension adjusting screw 130 protrudes from the upper surface of the upper beam 21 and functions as a tension adjusting knob of the cutting blade 3. Each tension adjusting screw 130 is fitted to the beam 21 so as to be rotatable around the central axis, but is immovably fitted to the beam 21 in the direction of the central axis. Accordingly, by rotating the head of each tension adjusting screw 130, the tension applying block 110 can be attracted toward the girder 21 or can be adjusted to move away from the girder 21. The tension holding plate 120 is fixed to the lower girder 22.

  As shown in FIG. 7, a V-shaped groove 111 is formed on the upper surface of the tension applying block 110 over the entire length of the tension applying block 110 as viewed from the side. 4 and 8, the tension applying block 110 has a plurality of slits 112 for inserting the cutting blade 3 from the back side of the tension applying block 110, and the tension applying block 110 in the width direction, that is, FIG. In FIG. 8, they are formed at regular intervals across the vertical direction. As shown in detail later, bosses are fixed to both end portions of each cutting blade 3 so that the bosses at the upper end portions of the respective cutting blades 3 can pass therethrough. A gap 23 having an appropriate width is opened between the two.

  As shown in FIGS. 4, 7, and 8, the tension holding plate 120 is manufactured by punching and bending a metal plate. In the tension holding plate 120, the side surface shape of the upper end edge portion is folded back into a V shape, and the ceiling portion at the upper end of the tension holding plate 120 is an inverted V-shaped groove 124. The tension holding plate 120 has a plurality of slits 121 for guiding the lower end of each cutting blade 3 from the back side into the tension holding plate 120 in the vertical direction of the tension holding plate 120 and the length of the tension holding plate 120. It is formed at regular intervals in the direction. In the middle of each slit 121 in the length direction, a widened portion 122 is formed so that the boss at the lower end of each cutting blade 3 can pass through. As shown in FIGS. 4 and 8, each widened portion 122 has a narrow width on one side of the slit 121 and a wide width on the other side.

  FIG. 6 shows a structure of a boss fixed to both ends of each cutting blade 3. The boss includes a male boss 140 and a female boss 150. The male boss 140 has a head portion as a main body and has a shaft portion 141 extending from the head portion along the central axis. The female boss 150 has a cylindrical shape with the same outer diameter as the outer diameter of the head of the male boss 140, and the inner diameter of the center hole 151 is substantially the same as the outer diameter of the shaft portion 141 of the male boss 140. The axial length of the female boss 150 is longer than the axial length of the head of the male boss 140, and is substantially the same as or longer than the axial length of the shaft portion 141 of the male boss 140. Yes. Holes for penetrating the shaft 141 of the male boss 140 are formed at both ends of each cutting blade 3, and the shaft 141 of the male boss 140 is passed through the hole from one side of the cutting blade 3. The center hole 151 of the female boss 150 is fitted into the shaft portion 141 of the male boss 140 protruding to the other surface side of the cutting blade 3. The male boss 140 and the female boss 150 are integrally fixed to the cutting blade 3 by a method such as caulking the shaft portion 141 of the male boss 140.

  As shown in FIG. 8, the relationship between the male and female bosses fixed to the respective cutting blades 3 is opposite between the one surface side and the other surface side of the cutting blade 3 between the one end side and the other end side. It has become. That is, in the example shown in FIG. 8, at the upper end of each cutting blade 3, the left side of each cutting blade 3 is a male boss 140, the right side is a female boss 150, and the lower end of each cutting blade 3 is Each cutting blade 3 has a female boss 150 on the left side and a male boss 140 on the right side. The widened portion 122 formed in each slit 121 of the tension holding plate 120 fixed to the lower spar 22 of the cutting blade fixing frame 2 is wide on the left side as shown in FIGS. And the right side is narrower.

  Since the boss of each cutting blade 3 is configured as described above and the widened portion 122 of each slit 121 of the tension holding plate 120 is formed as described above, when one end portion of the cutting blade 3 is passed through the slit 121 The female boss 150 can pass through the widened wide portion, and the widened portion having a narrower width can pass through the male boss 140. If it is assumed that the direction of the cutting blade 3 is reversed, the female boss 150 hits the widened portion having the narrower width, and the female boss 150 cannot pass through the widened portion. Cannot be mounted on the cutting blade fixing frame 2. The reason for this configuration is that each cutting blade 3 needs to be mounted so that the blade portion faces the back side of the cutting blade fixing frame 2.

  The lower end portion of each cutting blade 3 can be attached to the tension holding plate 12 as described above. With respect to the tension applying block 110, the upper end portion of each cutting blade 3 can be mounted by passing the cutting blade 3 through the slit 112 and passing the boss of the cutting blade 3 from the gap 23. Thus, after attaching the upper and lower ends of each cutting blade 3 to the tension applying block 110 and the tension holding plate 120, the pair of tension adjusting screws 130 are rotated to move the tension applying block 110 to the upper spar 21. attract. When the tension applying block 110 is attracted to the girder 21, the upper and lower bosses of each cutting blade 3 are formed in the V-shaped groove 111 of the tension applying block 110 and the inverted V shape of the tension holding plate 120 as shown in FIG. 7. The boss receiving portion 122 is driven into a portion corresponding to a V-shaped valley, and tension is applied to each cutting blade 3.

  The tension applied to the entire cutting blade 3 can be adjusted by a pair of tension adjusting screws 130. Since the tension of each cutting blade is not adjusted individually, the tension of all the cutting blades can be adjusted by adjusting the tension of each cutting blade more strongly like the tension adjustment of the cutting blade in the conventional food cutting device. The combined value becomes too strong, and the above-described problems can be prevented.

  Since the tension applied to the entire cutting blade 3 is adjusted by a pair of tension adjusting screws 130, the dimensional accuracy error of the cutting blade 3 and the male and female bosses 140, 150, the tension applying block 110 and the tension holding plate 120 are determined. Variations in tension occur in the respective cutting blades 3 due to the accuracy error. Depending on the case, even if a predetermined tension is applied as a whole, some of the cutting blades 3 may have a low tension and little tension. However, as described above, the upper and lower bosses of each cutting blade 3 are located at portions corresponding to the V-shaped valleys of the tension applying block 110 and the tension holding plate 120, so that the food is pushed to the cutting blade by a drive mechanism described later. When applied, the upper and lower bosses are pressed against the slopes of the V-shaped valleys of the tension applying block 110 and the tension holding plate 120 as indicated by arrows in FIG. When the bosses are pressed along these slopes, as shown by arrows in FIG. 7, a component force is generated in a direction to separate the bosses at both ends of the cutting blade 3 from each other, and tension is applied to the cutting blade 3. . If the pressing force to the cutting blade 3 by a foodstuff is large, this tension | tensile_strength will become large according to it. In this way, since the tension required when each cutting blade 3 functions as a cutting blade is applied, the tension applied to each cutting blade 3 may be weak, and the variation in tension between the cutting blades 3 is large. However, food cutting performance will not deteriorate.

  As described above, the cutting blade unit 100 configured as described above is provided along the pair of guide rails in which the left and right end edges of the cutting blade fixing frame 2 are fixed to the left and right side plates 4 in the vertical direction. It is attached to the food cutting device by being dropped. The cutting edge of each cutting blade 3 when the cutting blade unit 100 is mounted faces the back side of the food cutting device.

  Next, other components of the food cutting device will be described. As shown in FIG. 9, the food placing table 5 has an L-shaped upper half of the side surface shape, so that the food 10 before cutting is formed at the corners of the L-shaped horizontal and vertical sides. Can be placed. More specifically, the L-shaped portion extending in the horizontal direction is the bottom surface receiver 51 of the food 10, and the L-shaped portion extending in the vertical direction is the back surface receiver 52 of the food 10. There are several kinds of foods such as seaweed rolls received by the food placing table 5, and even if the food size is different, it is possible to hold it on the food placing table 5 correspondingly. A mechanism is provided. However, since such a mechanism is not directly related to the present invention, a description thereof will be omitted.

  In order to cut the food 10 placed on the food placing table 5 with the cutting blade 3, the food placing table 5 is formed with a slit 58 through which the cutting blade 3 can enter. The slits 58 are provided at the number and position corresponding to the number and installation positions of the cutting blades 3 fixed to the cutting blade fixing frame 2. In the illustrated embodiment, the number of divisions of the food 10 can be selected as 4, 6, or 8, so that the positions corresponding respectively to the above division numbers are centered on the central slit in the left-right direction. A slit 58 is formed in the bottom. Each slit 58 is deeply cut across a wide range including the bottom face receiver 51 and the back face receiver 52 so that the food blade 10 can be reliably cut by receiving the cutting blade 3.

  As shown in FIG. 9 and the like, the food placing table 5 is provided with restricting plates 56 for restricting both ends in the length direction of the food 10 to be placed at both ends of the back support 52. The restriction plate 56 is formed by bending a metal plate, and is attached to the back support 52 with a fixing screw. If the food 10 is, for example, a seaweed sushi roll, the size of the seaweed is standardized to 205 mm x 185 mm, so the length of the seaweed roll sushi before cutting depends on whether the seaweed is rolled horizontally or vertically. Changes. Therefore, the interval between the pair of regulation plates 56 is adjusted to match the length of the seaweed roll sushi.

  Next, the drive mechanism of the food mounting table indicated by reference numeral 6 in FIGS. 2, 3, and 9 will be described in detail. 2, 3, and 9, a motor 61 as a drive source is fixed to the inner surface of the left side plate 4, and a gear 62 fixed to the output shaft of the motor 61 is a gear 63 fixed to a shaft 64. Are engaged. The shaft 64 is rotatably supported across the left and right side plates 4, and drive arms 65 are fixed to both ends of the shaft 64 that penetrates the left and right side plates 4. The rotational driving force of the motor 61 is transmitted to the shaft 64 through the gears 62 and 63, and is configured to rotationally drive each driving arm 65 integral with the shaft 64 in a plane parallel to the outer surface of each side plate 4. Has been. Each drive arm 65 has a long hole 66 along a straight line passing through the rotation center of the shaft 64.

  As shown in FIG. 9, two shafts 53 and 54 are attached to the bottom of the food placing table 5 so as to penetrate the bottom in the horizontal direction and horizontally. The shafts 53 and 54 are parallel to each other, the shaft 53 is disposed at the center portion in the front-rear direction of the food placing table 5, and the shaft 54 is disposed at the rear portion in the front-rear direction of the food placing table 5. Of these two shafts 53, 54, both ends of the shaft 53 on the front side (the central portion in the front-rear direction of the food placing table 5) are fitted in the long holes 66 of the drive arm 65 on both sides. Therefore, when each drive arm 65 is rotationally driven around the shaft 64 together with the shaft 64, the shaft 53 is pushed by the wall surface of the long hole 66, and is regulated by a cam groove 91 described later with the rotation of each drive arm 65. However, the food mounting table 5 can also be moved. The food 10 also moves together with the food mounting table 5, and the food 10 passes through the position of the cutting blade 3 and is cut in the middle of the movement.

  The left and right side plates 4 are formed with cam grooves 91 that overlap each other when viewed from the side. Both ends of the two shafts 53 and 54 attached to the food placing table 5 are fitted in these cam grooves 91, and the two shafts 53 and 54 are supported by the side wall surfaces of the cam grooves 91. In addition, it functions as a cam follower of the food placing table 5 with respect to the cam groove 91. The height position and posture of the food mounting table 5 are determined by the difference in height position and relative height between the two shafts 53 and 54, and the relative height positional relationship between the two shafts 53 and 54 is a cam. It depends on the shape of the groove 91.

  2 and 9 show an initial position before starting a series of food cutting operations. In this initial position, each drive arm 65 is in a posture that rises to the maximum nearly near vertical. In this aspect, as shown in FIG. 9, the two shafts 53 and 54 are fitted to the upper end portion of the cam groove 91 so that the food placing table 5 is at the highest position. As shown in FIGS. 10 and 11, the upper end of the cam groove 91 is a gentle arc 92, and the back of the arc 92 is gradually lowered. Then, when the food placing table 5 is at the highest position as described above, the two shafts 53 and 54 are in the arc portion 92, so that the food placing table 5 is slightly warped backward. Take.

  As shown in FIGS. 10, 12, etc., the cam groove 91 is continuous with an arc portion 93 extending obliquely downward from the arc portion 92, and the arc portion 93 is further formed into a linear portion 94 extending obliquely downward. It is continuous. When the food placing table 5 starts to move from the initial position and the food 10 moves together with the food placing table 5 and starts to contact the cutting blade 3, the two shafts 53 and 54 reach the arc portion 93. When the two shafts 53 and 54 pass through the arc portion 93, the posture of the food placing table 5 is gradually lowered while moving downward. That is, the cam groove is formed so that the dip angle between the food placing table 5 and the food 10 gradually increases, the approach angle of the cutting blade 3 with respect to the food 10 continuously changes, and the relative speed of the food 10 with respect to the cutting blade 3 increases. The lower surface of the arc portion 93 of 91 is a convex surface.

  As described above, when the food 10 is placed on the food placing table 5 taking the food 10 and the drive mechanism 6 is operated, the two shafts 53, 54 are moved from the arc portion 92 of the cam groove 91. It moves to the arc part 93 and further moves to the straight part 94. When the shafts 53 and 54 pass through the circular arc portion 93, the height position of the shaft 53 gradually becomes lower than the height position of the shaft 54, the posture of the food placing table 5 becomes the forward tilted posture, and the forward tilt angle is increased. Gradually grows.

  In this way, when the food placing table 5 is changing its posture, the cutting blade 3, the food placing table 5, and the shaft so that the food 10 placed on the food placing table 5 starts to contact the cutting blade 3. 53, 54 and the cam groove 91 are set in a positional relationship. The shafts 53 and 54 are guided to the straight portion 94 of the cam groove 91 after passing through the circular arc portion 93, and the food placing table 5 is inclined from the top to the bottom as described above while maintaining the forward tilt posture. It moves linearly and the food is cut by the cutting blade 3. The cut food 10 moves to a take-out member 8 described below, and then the drive mechanism 6 operates in the reverse direction to return the food placing table 5 to the original position.

  Such a reciprocating operation of the drive mechanism 6 can be performed, for example, by simply pressing a start button. When the start button is pressed, the motor 61 is driven in the forward direction, and the drive arm 65 is rotated in the clockwise direction in FIG. The rotation direction of the drive arm 65 is the forward movement direction, and the motor 61 is driven in the forward rotation direction until a movement limit in the forward movement direction is detected. When the drive arm 65 reaches the limit position in the forward movement direction, the motor drive direction is switched to the reverse rotation direction, the drive arm 65 is driven in the backward movement direction, and when the movement limit in the backward movement direction is detected, the motor 61 is driven. Stop. As the drive arm 65 reciprocates in this way, the food placing table 5 descends while changing its posture as described above, and the food 10 held on the food placing table 5 is cut by the cutting blade 3. Only the food mounting table 5 returns to the original position.

  Next, the configuration of the food receiving unit will be described in detail. As shown in FIG. 1 to FIG. 3, a take-out portion 8 for the cut food 10 is provided at the front lower portion of the apparatus. The take-out unit 8 includes an inclined guide member 81 that is fixed so as to incline in a direction in which the lower side protrudes toward the front side of the apparatus, and a receiving member 82 that is guided by the inclined guide member 81 and moves up and down. A plurality of ribs 85 are formed on the front surface of the inclined guide member 81 in parallel to the vertical direction so that the cut food 10 can be smoothly lowered along the inclined guide member 81, so The resistance is reduced.

  The receiving member 82 projects in a direction perpendicular to the front surface of the inclined guide member 81, and thus obliquely upward. The receiving member 82 is manufactured by bending, and a base portion thereof is a sliding portion 86 that is guided by the front surface of the inclined guide member 81 and moves up and down obliquely. Bending portions 88 are formed at both left and right end portions of the sliding portion 86. Each bent portion 88 passes through guide grooves 87 formed in the vertical direction at both ends of the inclined guide member 81, lies on the back side of the inclined guide member 81, and further protrudes on both sides of the inclined guide member 81 to slide. Screwed to the front surface of the member 89. Each sliding member 89 is a rectangular parallelepiped member, and is slid by being guided by a guide rail 90 having a U-shaped cross section. The guide rail 90 is fixed to the outer side surfaces of the left and right side plates 4 so as to be parallel to the inclined guide member 81 and with the open end of the U-shaped cross section facing the side. Each guide rail 90 is formed with a relief hole 91 for the bent portion 88 so as not to be an obstacle when the bent portion 88 of the receiving member 82 slides with the sliding member 89.

  The receiving member 82 is driven by the rotation of the pair of left and right link arms 30. Each link arm 30 is attached to a position closer to the lower side of the outer surface of the left and right side plates 4 so as to be rotatable within a vertical plane that is parallel to the side plates 4 with a common axis 31 as the center. A small gear 32 concentric with the shaft 31 is fixed to the base end portion of the link arm 30 attached to the left side plate 4 when the food cutting apparatus according to the present embodiment is viewed from the front. A long hole 33 along a line passing through the center of the shaft 31 is formed at the tip of each link arm 30, and a pin 34 planted on the side surface of each sliding member 89 is fitted in each long hole 33. Yes. Therefore, when the link arm 30 is rotationally driven, the pin 34 is pushed by the side wall of the elongated hole 33, and the receiving member 82 is guided to the guide rail 90 together with the pin 34 so as to rise and fall obliquely in the vertical direction. Has been.

  In this embodiment, the drive source of the link arm 30 is a motor 61, and the driving force of the motor 61 is transmitted to the link arm 30 through the following cooperation mechanism. A pin 68 is planted on the outer surface near the center in the length direction of each drive arm 65. The fan-shaped large gear 20 is held by the shaft 64 which is the rotation center of the drive arm 65. The large gear 20 has a shaft 64 at a position corresponding to the center of the fan, and a gear is formed along an arc centered on the shaft 64. The large gear 20 is rotatable relative to the shaft 64, and the gear forming portion meshes with the small gear 32.

  In the large gear 20 having a sector shape, a triangular cooperation plate 40 is fixed to the upper side surface in FIG. The link plate 40 has a long hole 41 in a direction substantially orthogonal to the length direction of the drive arm 65. A pin 68 of the drive arm 65 is fitted in the long hole 41. However, the width of the long hole 41 is sufficiently large with respect to the outer diameter of the pin 68, and when the pin 68 moves within the range of the length direction of the long hole 41, it does not contact the wall surface that defines the long hole 41. When the pin 68 reaches both ends of the long hole 41 in the length direction, the large gear 20 is driven.

  In the embodiment shown in FIG. 9, the drive arm 65 rotates counterclockwise to the maximum, and the food placing table 5 moves to the uppermost position to accept the food 10 as described above. In this embodiment, the pin 68 is located at one end of the long hole 41 of the linkage plate 40, pulling up the linkage plate 40, and rotating the large gear 20 integrated with the linkage plate 40 counterclockwise about the shaft 64. . The rotational force of the large gear 20 is transmitted to the small gear 32 to rotate the small gear 32. In the embodiment shown in FIG. 9, the small gear 32 is rotated to the maximum in the clockwise direction, and the sliding member 89 is lowered to the limit position by the link arm 30 that rotates integrally with the small gear 32 in the clockwise direction. The movement of the sliding member 89 is restricted by hitting the lower stopper 35 at the lower limit position, and the lowering position is stably held together with the receiving member 82 integrated with the sliding member 89.

  The drive arm 65 is driven to rotate clockwise from the position shown in FIG. 4 until the pin 68 hits the upper edge of the large gear 20 as shown in FIG. There is no member linked to the pin 68 just by moving while drawing an arc. The operation mode shown in FIG. 11 is a mode in which the food 10 is cut about half by the cutting blade 3. As the drive arm 65 further rotates clockwise from the operation mode shown in FIG. 11, the pin 68 pushes the upper edge of the large gear 20 and rotates the large gear 20 clockwise. The rotational force of the large gear 20 is transmitted to the small gear 32, and the small gear 32 is rotationally driven in the counterclockwise direction. This rotational force is transmitted to the link arm 30, and the link arm 30 is counterclockwise about the shaft 31. Is driven to rotate. 11 and 12 show the counterclockwise rotation of the small gear 32 and the link arm 30 caused by the clockwise rotation of the large gear 20. As the link arm 30 rotates counterclockwise, the sliding member 89 and the receiving member 82 substantially integral therewith are guided through the inclined guide member 81 through the elongated hole 33 and the pin 34 so as to be pushed upward obliquely. It has become.

  The gear ratio of the large gear 20 and the small gear 32 is increased with respect to the ratio of the length of the link arm 30 and the vertical movement distance of the food placing table 5, and the small gear 32 for the rotation angle of the large gear 20. The rotation angle is designed to be sufficiently large. However, since the stroke that the sliding member 89 and the food placing table 5 can actually move is limited, when the small gear 32 is rotationally driven beyond the necessary stroke of the food placing table 5, A slip mechanism is provided so that slip occurs between the small gear 32 and the link arm 30. The sliding mechanism is also called a torque limiter. Although a specific configuration of the sliding mechanism is not illustrated, a known configuration may be appropriately selected and adopted. For example, the sliding mechanism may be configured by interposing a repulsive coil spring between the small gear 32 and the link arm 30.

  In the embodiment shown in FIG. 12, the sliding member 89 hits the upper stopper 36, and the sliding member 89 and the food cradle 5 are at the ascent limit position. Even when the sliding member 89 hits the stopper 36, as shown in FIG. 13, the large gear 20 rotates in the clockwise direction and the small gear 32 is driven to rotate in the counterclockwise direction. However, since the sliding member 89 has reached the movement limit, the link arm 30 cannot rotate, and the sliding mechanism absorbs an extra movement stroke of the driving member 89.

  The link arm 30 is provided on both the left and right sides of the food cutting device according to the present embodiment when viewed from the front, and drives the food placing table 5 from both the left and right sides. In contrast, the linkage plate 40, the large gear 20, the small gear 32, and the sliding mechanism that transmit the driving force to the pair of link arms 30 are provided only on the left side of the apparatus. The pair of link arms 30 are integrally coupled by a common shaft 31 so that the pair of link arms 30 are driven integrally.

  Next, a series of operations of the embodiment configured as described above will be described. 2, 3 and 9 show the initial state before the operation starts. The drive arm 65 is at the rotation limit position in the counterclockwise direction in FIG. The food placing table 5 has two shafts 53 and 54 in the arc portion 92 at the upper end of the cam groove 91 to take the placing posture of the food 10 before cutting. The pin 68 of the drive arm 65 hits one end of the long hole 41 of the cooperation plate 40, and the large gear 20 is rotated counterclockwise in FIG. Due to the rotation of the large gear 20, the small gear 32 rotates in the clockwise direction in FIG. 9, and the sliding member 89 and the receiving member 82 are in the downward movement limit position.

  In the initial state, when the food 10 is placed on the food placing table 5 and the start button is operated, the motor 61 is activated and the drive mechanism 6 starts operating. The drive arm 65 of the drive mechanism 6 is rotated clockwise as shown in FIG. 5 through the gear trains 61 and 62 and the shaft 64, and the shaft 53 of the food placing table 5 fitted in the long hole 66 is connected to the cam groove 91. Is moved along. The shaft 54 moves along the cam groove 91 together with the shaft 53. The height position and posture of the food placing table 5 are determined by the difference between the height positions of the two shafts 53 and 54 and the mutual height positions. When the shafts 53, 54 reach the position of the arc portion 93 of the cam groove 91, the height position of the shaft 53 is continuously lowered with respect to the height position of the shaft 54, so that the food placing table 5 is tilted forward. The forward leaning posture gradually deepens.

  As described above, the position at which the food placing table 5 starts to take the forward leaning posture is when the food 10 starts to contact the cutting blade 3. At the beginning of contact between the food 10 and the cutting blade 3, the relative angle between the cutting blade 3 and the food 10 is increased by continuously changing the approach angle of the cutting blade 3 with respect to the food 10. FIG. 10 shows an operation mode at this time. Thus, the cutting blade 3 is made easy to enter the food 10 at the beginning of cutting, and the food 10 is cut smoothly.

  When the shafts 53 and 54 of the food placing table 5 reach the straight portion 94 of the cam groove 91, the food placing table 5 moves obliquely downward along the straight portion 94 while maintaining the maximum inclination angle. During this time, while intersecting with the cutting blade 3 that is fixed in a doubly-supported manner in the vertical direction, the food 10 moves together with the food placing table 5 obliquely downward at a constant relative speed, and the food 10 is cut into a ring shape. 11 to 13 show this operation mode, and FIG. 13 shows a state immediately after the completion of cutting. As described above, the food placing table 5 is provided with a relief groove for the cutting teeth 3.

  FIG. 11 shows an operation mode in which the food 10 is cut about half during the cutting process of the food 10 and the pin 68 of the drive arm 65 starts to hit the large gear 20. As the drive arm 65 further rotates, the pin 68 pushes the large gear 20 downward, causing the large gear 20 to rotate clockwise as shown in FIGS. The rotational force of the large gear 20 is transmitted to the small gear 32, causing the small gear 32 to rotate counterclockwise. The rotational force of the small gear 32 is transmitted to the link arm 30 via the sliding mechanism, and the link arm 30 is driven to rotate counterclockwise. By the rotation of the link arm 30, the sliding member 89 and the receiving member 82 are guided by the inclined guide member 81 and the guide rail 90 and pushed upward obliquely. FIG. 11 shows a state in which the receiving member 82 is rising obliquely upward, and FIG. 12 shows a state in which the receiving member 82 is raised to a limit position where it hits the upper stopper 36.

  The inclination angle of the linear portion 94 of the cam groove 91 and the inclination angle of the guide rail 90 are the same, and the vertical movement direction of the food placing table 5 along the linear portion 94 and the receiving member along the guide rail 90 The vertical movement direction of 82 is parallel. Then, as shown in FIG. 12, the receiving member 82 that has been raised to the upper limit position is located in front of the moving direction of the food 10 that is placed on the food placing table 5 and descends obliquely together with the food placing table 5. And is ready to receive food 10.

  After the receiving member 82 is raised to the upper limit position, the drive arm 65 is still driven to rotate clockwise as shown in FIG. 13, and the drive arm 65 lowers the shaft 53. The shaft 53 moves down along the straight portion 94 of the cam groove 91 together with the shaft 54, and the food placing table 5 moves obliquely downward while holding the food 10 and maintaining the forward tilting posture. FIG. 12 shows an operation mode immediately before completion of cutting of the food 10 held on the food placing table 5. In this operation mode, the food placing table 5 moves as described above, and the food 10 held on the food placing table 5 is in contact with the receiving member 82.

  When the thickness of the food 10 is larger than that shown in the figure, the contact timing of the food 10 with respect to the receiving member 82 at the rising limit is early, and the receiving member 82 is pushed down by the descending food 10. The sliding member 65 and the receiving member 82 are pushed downward by this pushing force, and the link arm 30 is forcibly pushed back in the clockwise direction in FIG. The forced clockwise rotation of the link arm 30 is allowed by the sliding mechanism between the link arm 30 and the small gear 32 sliding.

  After the cutting of the food 10 by the cutting teeth 3 is completed, the drive arm 65 is driven to rotate clockwise, reaching the clockwise limit shown in FIG. During the operation mode shown in FIG. 13 to the operation mode shown in FIG. 14, the food mounting table 5 still moves downward obliquely due to the fitting of the long hole 66 of the drive arm 65 and the shaft 53. Since the food 10 is lowered together with the food placing table 5, the cutting of the food 10 is completed, and the receiving member 82 is pushed by the food 10 and lowered. When the drive arm 65 rotates in the clockwise direction, the large gear 20 is rotated in the clockwise direction by the pin 68, and the small gear 32 is rotated in the counterclockwise direction. However, since the sliding mechanism is interposed between the small gear 32 and the link arm 30, the rotational force of the small gear 32 is not transmitted to the link arm 30, and the link arm is caused by the forced lowering of the receiving member 82. Thirty clockwise rotations are allowed.

  In this way, when the cutting of the food 10 is completed and the operation mode in which the delivery of the food 10 to the receiving member 82 is completed, the rotation direction of the motor 61 is switched to the opposite direction. FIG. 14 shows a state in which the motor 61 is reversely rotated and the drive arm 65 is rotating counterclockwise and returning toward the initial position. As the driving arm 65 returns, the food mounting table 65 rises along the cam groove 91 due to the fitting of the shaft 53 of the food mounting table 65 and the long hole 66 of the driving arm 65. Until the return operation of the drive arm 65, the pin 68 of the drive arm 65 simply moves in a circular arc within the range of the width and length of the long hole 41 of the linkage plate 40, and acts on the linkage plate 40. do not do. Therefore, the large gear 20 does not rotate, and the link arm 30 and the receiving member 82 do not move.

  When the drive arm 65 rotates counterclockwise and the food placing table 5 returns to the initial position, when the pin 68 of the drive arm 65 reaches one end of the long hole 41 of the linkage plate 40, the pin 68 and the linkage plate 40 are moved. Thus, the large gear 20 is driven to rotate counterclockwise. Due to the rotation of the large gear 20, the small gear 32 is rotationally driven in the clockwise direction, the driving force is transmitted to the link arm 30 through the sliding mechanism, and the link arm 30 is rotationally driven in the clockwise direction. The rotation of the link arm 30 causes the receiving member 82 to move obliquely downward together with the sliding member 89, the sliding member 89 hits the stopper 35, and reaches the lower limit position of the sliding member 89 and the receiving member 82. At the lower limit position of the receiving member 82, the cut food 10 supported by the receiving member 82 is in the take-out portion 8, and the food 10 can be taken out.

  Even after the receiving member 82 reaches the lower limit position, the drive arm 65 is driven in the counterclockwise direction, and when the food placing table 5 returns to the initial position shown in FIG. Stops. From the middle of the return operation to the return to the initial position shown in FIG. 15, the large gear 20 is rotated counterclockwise and the small gear 32 is rotated clockwise by the pin 68, and clockwise torque is applied to the link arm 30. Take it. However, the rotation of the link arm 30 is limited by the stopper 35, and the small gear 32 and the link arm 32 are slid by the sliding mechanism, and the receiving member 82 remains in the take-out portion 8.

  When the cut food 10 is taken out from the receiving member 82 in the take-out part 8, put on the food placing table 5 moving to the food supply part at the top of the apparatus, and the start switch is pushed again, the above-mentioned The food 10 is cut through a series of operations, and the cut food 10 reaches the take-out unit 8.

  The food cutting device according to the embodiment described above does not drop the cut food 10 by its gravity, but goes to the receiving by the receiving member 82 and lowers the receiving member 82 that has received the food 10 to the take-out portion 8. It is configured as follows. Therefore, since the food 10 after cutting reaches the take-out portion 8 while maintaining a predetermined posture, the workability of taking out the food after cutting can be further improved. Moreover, since the attitude | position of the foodstuff 10 which reached the taking-out part 8 is in order, the appearance is also beautiful.

  In the above embodiment, the drive source of the food placing table 5 and the drive source of the receiving member 82 that receives the cut food 10 are used as the common motor 61 in order to reduce the cost. Then, in order to make the drive reduction common, the drive mechanism 6 of the food placing table 5 and the drive mechanism of the receiving member 82 are linked, and the receiving member 82 is moved from the middle of the food cutting process by driving the food placing table 5. It is configured to rise to the food receiving position. Further, a slip mechanism is provided in the drive mechanism of the receiving member 82 in order to absorb the difference in movement stroke between the drive mechanism 6 of the food placing table 5 and the drive mechanism of the receiving member 82.

  FIG. 16 shows another embodiment of the drive mechanism 6 of the food placing table 5 and the drive mechanism of the receiving member 82. In this embodiment, there is no linkage mechanism that links the driving mechanism 6 of the food placing table 5 and the driving mechanism of the receiving member 82 of the cut food 10, and the driving mechanism 6 and the receiving member 82 of the food placing table 5 are driven. Each mechanism has a drive source. In the embodiment shown in FIG. 16, the same components as those of the first embodiment are denoted by the same reference numerals, and the description of the same components will be simplified.

  In FIG. 16, the drive mechanism 6 of the food mounting table 5 includes a motor 61 as a driving source, gears 62 and 63, a drive arm 65, and two shafts 53 and 54 penetrating the food mounting table 5, as in the above embodiment. And a cam groove 91 formed in the side plate 4. The operation of the food placing table 5 by the rotation of the drive arm 65 and the cutting operation of the food 10 by the cutting blade 3 are the same as in the first embodiment.

  A motor 101 different from the motor 61 is provided as a drive source of a drive mechanism that drives the receiving member 82 of the cut food 10. A gear 102 is fixed to the output shaft of the motor 101, and the gear 102 meshes with the gear 32. The gear 32 has a shaft 31 as a center of rotation, as in the above-described embodiment, and a link arm 30 having the shaft 31 as a center of rotation is fitted to the shaft 31. A sliding mechanism is provided between the link arm 30 and the gear 32 as in the above embodiment. The link arm 30 is linked to the sliding member 89 by a long hole and a pin as in the above embodiment, and the sliding member 89 is coupled to the receiving member 82 substantially integrally.

  The rotation range of the link arm 30 that uses the motor 101 as a drive source is a rotation that can obtain a sliding range sufficiently larger than the sliding range of the sliding member 89 regulated by the lower stopper 35 and the upper stopper 36. Even if the sliding member 89 is in contact with the upper and lower stoppers 36 and 35, the rotational driving force applied to the link arm 30 is released by the sliding mechanism.

  In the embodiment shown in FIG. 16, when a food 10 such as rolled sushi is placed on the food placing table 5 in the illustrated initial position and the start button is pressed, the motor 61 is activated and the food placing table 5 is moved to the food 10. At the same time, it moves diagonally downward while changing its posture. Meanwhile, the food 10 is cut into a plurality of pieces by the cutting blade 3. The motor 101 is started in the middle of the cutting process, the link arm 30 is driven counterclockwise through the gears 102 and 32, and the motor 101 stops by moving to a position where the sliding member 89 contacts the stopper 36. The receiving member 82 integral with the sliding member 89 also moves obliquely upward, and is ready to receive the food 10 to be cut.

  When the cutting of the food 10 is completed, the food 10 is delivered to the receiving member 82, and the receiving member 82 is pushed downward according to the size of the food 10. The pushing mechanism causes the sliding mechanism to slide, and the link arm 30, the sliding member 89, and the receiving member 82 are pushed back.

  When the drive arm 65 is driven to rotate at an angle required to cut the food 10, the rotation direction of the motor 61 is switched to the opposite direction, and the food placing table 10 returns to the initial position. The motor 101 is also rotated in the reverse direction, the link arm 30 is rotated in the clockwise direction until the sliding member 89 contacts the stopper 35, and the driving of the motor 61 is stopped. At this time, the receiving member 82 is in the food take-out portion 8, and the cut food 10 supported on the receiving member 82 while maintaining a predetermined posture can be efficiently taken out.

  The gist of the present invention resides in the configuration of the cutting blade unit 100 described above. Therefore, the drive mechanism of the food mounting table is arbitrary, and is not limited to the configuration of the drive mechanism 6 employed in this embodiment. Whether or not to provide a mechanism for receiving the food to be cut is also arbitrary. Further, it is optional to fix the cutting blade unit and move the target food to cut the target food, or move the cutting blade unit to cut the fixed target food.

  According to the cutting blade unit 100 configured as described above, even if the tension adjustment of the cutting blade 3 is rough and the tension is loose, an appropriate tension works for each cutting blade during food cutting. That is, since appropriate tension is automatically applied to each cutting blade, the tension adjustment of the cutting blade may be rough or the tension may be adjusted loosely. Therefore, it is also possible for the user of the food cutting device to replace the cutting blade and adjust the tension. Since it can avoid that the tension | tensile_strength as the whole some cutting blade becomes too strong, the cutting blade holding | maintenance frame 2 does not deform | transform and can reduce deterioration of food cutting performance.

  The bosses provided at both ends of each cutting blade 3 have different directions on one end side and the other end side so as to have directionality, and receive the bosses at both ends of each cutting blade 3. The widened portion 122 of the tension holding plate 120 is also provided with directionality by making a difference in width, and the cutting blade 3 cannot be attached to the holding frame 2 unless the cutting blade 3 has a predetermined orientation. Therefore, it is not necessary to mount the cutting blade 3 in the wrong direction. From this point, it is easy to replace the cutting blade 3 on the user side of the food cutting apparatus.

  The food cutting device according to the present invention mainly assumes rolled sushi such as seaweed roll as the main target food, but can cut columnar, prismatic, or rod-shaped foods into round slices. Therefore, the food to be cut can be used for cutting rolled sushi, kneaded products such as bamboo shoots and bamboo rings, and other foods.
