TECHNICAL FIELD OF THE INVENTION
The present invention relates to a food discharging device of an automated food molding machine for producing, for example, nigiri sushi.
[0002]
[Prior art]
As a nigiri sushi molding machine, for example, the one shown in FIG. 6 is known.
That is, cooked rice is dispensed by a predetermined amount from the feeding mechanism a onto a lower and intermittently rotating conveyor belt b, and the fixed amount of cooked rice c is formed by a forming mechanism d disposed above the conveyor belt b, The molded cooked rice c 'having a predetermined shape is obtained by gripping with d', and a wasabi (not shown) and a story e are placed on the molded cooked rice c 'while being transported by the intermittent transport conveyor belt b. This is a configuration in which cooked sushi g is produced by re-grip-forming rice rice c ′ and material e by the molding mechanism f.
[0003]
The nigiri sushi g thus produced is transported to the downstream end thereof by an intermittent transport conveyor belt b, and then discharged by a discharge device h to a tray (not shown) or a packaging device i schematically shown in FIG. And then wrapped by the packaging device i.
[0004]
Meanwhile, as shown in FIGS. 6 and 7, the conventional food discharging device h is capable of reciprocating between the upper portion of the intermittent conveyor belt b and the upper portion of the discharging portion of the packaging device i and the like, and is capable of moving up and down. A pair of openable and closable movable members o, o 'connected to the cylinder m via links n, n' are pivotally mounted on both left and right sides of the main body 1 supported on the support shaft k via the arms j, j. A pair of food holding plates p and p 'are respectively fixed and suspended on the movable members o and o'. On the other hand, a food push rod r which can be raised and lowered by a cylinder q fixed on the rear side is mounted on the main body l. It is arranged.
[0005]
[Problems to be solved by the invention]
However, the above-mentioned conventional food discharging device, as shown in FIG. 7, grips the formed food g from both left and right sides thereof with a pair of holding plates p and p 'and lifts it upward to pack it. After being transferred to the upper part of the discharge unit such as the apparatus i or a tray (not shown), the pair of holding plates p and p 'are opened to release the gripping, and at the same time, the food g is wrapped by pressing down the rod r by the cylinder g. Since the structure is such that the food g is discharged onto the apparatus i or the like, not only the food g is easily deformed by the gripping force of the pair of holding plates p and p ', but also the depression above the food g is caused by the pushing force of the push rod r. s is easily formed and the appearance deteriorates, and as a result, the product is deformed or the depression s is formed and then packaged, which leads to a decrease in commercial value.
[0006]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the related art, and is capable of discharging without deformation or depression, and since remolding and discharging can be realized in the same apparatus and simultaneously, a food product with high working efficiency is provided.

[0028]
Thus, according to the food discharging device of the food molding machine having the above configuration, the molded product C is transferred and discharged as follows.
First, by the forward rotation of the cam 41, the spline shaft 25 is lowered via the lever 37, the food discharging device is lowered via the arm 26 and the holder 1, and at the same time, the cylinder 33 is turned on and the protruding rod 32 is lowered. When the upper end of the sliding body 6 is pressed downward, the sliding body 6 descends against the spring force of the compression spring 7, and moves through the support plate 8, the links 15, 15, and the arms 17, 17. , 13 are respectively rotated inward to clamp the mold, and as shown in FIG. 4, the rice A and the material B placed on the rice A are once grasped.
[0029]
Next, when the cylinder 33 is turned off while the spline shaft 25 is slightly raised through the lever 37 by the reversal of the cam 41, the sliding body 6 is raised by the elastic resilience of the compression spring 7, and the support plate 8, the link 15 , 15, and a pair of movable dies 13, 13 are pivoted outward to open the mold via the arms 17, 17, and release the grip of the cooked rice A and the spoiler B.
[0030]
Next, when the spline shaft 25 is lowered via the lever 37 by the forward rotation of the cam 41 and the cylinder 33 is turned on, the pair of movable dies 13, 13 are turned inward and clamped in the same manner as described above. , Hold rice A and spoiler B again.
[0031]
While maintaining the above state, the spline shaft 25 is raised via the lever 37 by reversing the cam 41 to slightly raise the food discharging device, and the spline shaft 25 is moved via the connecting rod 40 and the arm 36 by the lever 39. Is rotated in the direction around the axis, whereby the arms 26 and 28 are rotated in the direction of arrow B shown in FIG. 3, and the food discharge device is moved from the upper end of the downstream end of the intermittent conveyor belt b to the upper portion of the packaging device i and the like, that is, After being moved laterally to the upper part of the discharge section, it is lowered by the cam 41, lever 37, spline shaft 25, arms 26 and 28, and the cylinder 33 is turned off. The pair of movable dies 13, 13 are turned outward via the links 15, 15, and the arms 17, 17, and the cylinder 31 is turned on while opening the mold. Projecting rod 30 is lowered, pressing down against the ejector 4 the spring force of the compression spring 23. Thereby, the molded product C is forcibly discharged from the molding and holding mechanism 3 to the discharge portion of the packaging device i or the like by the molded product pushing plates 22a attached to the tips of the push rods 22.
[0032]
Next, by rotating the arms 26 and 28 in the direction of arrow a shown in FIG. 3 through the cam 41, lever 39, connecting rod 40, arm 36, and spline shaft 25, the molded article discharging device is moved to the above-described discharging section. When the cylinder 31 is turned off, the ejector 4 is pushed up and returned by the elastic resilience of the compression spring 23, and is used for the next reshaping, transporting, and discharging of the cooked rice A and the material B. Be provided.
[0033]
【The invention's effect】
Since the present invention is configured as described above, the molded article is grasped and simultaneously re-molded by the molding and holding mechanism including the upper fixed mold and the pair of left and right movable molds, and the molded article is kept in the same state. The molded product is not deformed, but rather is formed into a predetermined shape, and the ejecting rod of the ejector is released at the same time as the molding and holding mechanism releases the molded product. Extrusion is performed by the extrusion plate provided at the lower end, so that no dents are formed on the surface of the molded product, etc., and the molded product having a uniform and uniform shape and having a good appearance is transferred to the discharge unit. Since the discharge can be performed, and the remolding and discharge of the molded product can be performed simultaneously with the same apparatus, the working efficiency can be greatly improved.
