  However, it has been found that the sheath peeling apparatus of Patent Document 1 is suitable for the sheath peeling of soybeans and green soybeans, but is not suitable for the sheath peeling of peas (also called green peas). In addition, even in a sheath peeling device suitable for broad beans developed by the present applicant, it was not possible to take out the beans with good yield from the pea sheath. The size and thickness of the beans are different from soybeans, green soybeans, and even broad beans. Especially, the peas are thicker than the broad beans, and the hardness of the pods is harder. Therefore, based on the conventional configuration etc., only the design change due to the difference in size such as the change in the size and shape of the roller did not provide a sufficient yield, and it did not reach the one suitable for pea pod peeling. is there. Therefore, the present applicant has begun to develop a pod peeling apparatus particularly suitable for pea pod peeling.

  An object of the present invention is to provide a pod peeling apparatus particularly suitable for pea pod peeling.

In order to achieve the above object, the sheath peeling apparatus according to the present invention includes a conveying means for conveying a pod containing beans, and a sheath containing beans that have been conveyed by the conveying means , in a direction perpendicular to the longitudinal direction of the pod. A cutting means for making a plurality of cuts, and two rollers arranged at the subsequent stage of the cutting means, the two rollers having a gap shorter than the thickness of the bean pod between the peripheral surfaces thereof. Rotating in opposite directions so that the pods with beans that are arranged facing each other and are conveyed from the cutting means are pulled in the gap, while the beans are squeezed out from the pods with beans before the gap in the conveyance direction, Only the sheath is drawn into the gap and sent out to the rear side in the conveyance direction of the gap.

  According to the sheath peeling apparatus of the present invention, it is possible to easily and reliably peel beans (especially peas).

  Embodiments of the present invention will be described below with reference to the drawings. However, such an embodiment does not limit the technical scope of the present invention. The sheath peeling device disclosed in the following embodiments is particularly suitable for peeling peas (also referred to as so-called green peas), but is not limited to pea pod peeling, but other pod pods. Applicable to stripping.

  FIG. 1 is a side view showing an overall configuration of a sheath peeling apparatus in an embodiment of the present invention, and FIG. 2 is a top view thereof. In the sheath peeling device, a transport body that transports peas thrown from a throwing chute (guide part) 12 is fixed to a movable base 10 having casters.

  The transport body includes two transport rollers 14a and 14b and a belt body 14c stretched over them. The roller 14b rotates the belt body 14c by the chain drive by the motor 16, and the end member on the belt body 14c is rotated. A bean is conveyed toward the upper left direction of FIG.

  A rotating blade 20 that is rotated by a motor 18 is provided in the charging chute 12, and the rotation of the rotating blade 20 causes the peas stacked in the charging chute 12 to be scattered on the conveying surface of the belt body 14c. Eliminate the overlapping state.

  FIG. 3 is a schematic view showing peas conveyed on the belt body 14c. A plurality of partition plates 22 (six partition plates 22 between the wall portions 24 on both sides in FIGS. 2 and 3) extend in parallel in the transport direction (traveling direction) on the transport surface of the belt body 14c. Has been placed. The partition plate 22 is arranged at a width interval (for example, about 20 mm) approximately 1 to 2 in the short-side length of the pea, and is passed to the wall portions 24 on both sides thereof so as to cross the belt carrier 14c. The support plate 26 is attached. The support plate 26 is fixed to the wall portion 24. When the pea conveyed on the belt body 14c hits the partition plate 22, the longitudinal direction of the pea is aligned with the conveyance direction, and one or two peas are separated by the wall 24 and the partition plate 22 on both sides. Each of the partitioned space passages (lanes) 28 enters the space, and the peas are conveyed through the space passage 28 with the longitudinal direction of the peas aligned with the traveling direction.

  The cutting rollers 30 are provided by the number of the interval passages 28 (seven in FIG. 2 and FIG. 3) formed by the wall portions 24 and the partition plates 22 on both sides, and the vicinity of the exit of the interval passages 28 (conveyance of the belt body 14c). Arranged in parallel to the direction end). The cutting roller 30 shares its driving source with the motor 16 that drives the conveying roller 14b, and rotates in the opposite direction to the conveying roller 14a. An independent motor dedicated to the cutting roller 30 may be prepared.

  FIG. 4 is a front view and a plan view showing the cutting roller 30. The cutting roller 30 has, for example, a gear shape having tapered teeth, and the tip portion of the teeth has a shape that is sharp enough to cut into the pea pod. FIG. 5 is a schematic view of a pea with a notch in the pod. The shape of the peas shown in the figure is schematically shown, the actual shape is uneven, and the length, depth, position, etc. of the cuts are also uneven due to the difference in actual shape (such as irregularities) It becomes the aspect of. The distance between the tip portion of the tooth directly under the cutting roller 30 and the conveying surface facing it is a cut on the top pod of the pea passing therethrough (preferably, a cut through the top pod). The height position of the incision roller 30 is adjusted as appropriate so that the intervals are as large as possible.

  A pair of rollers 32 and 34 are disposed on the rear side of the end portion of the belt body 14c where the cutting roller 30 is disposed. The rollers 32 and 34 have a rotating shaft extending in a direction crossing the belt body 14c, and the rollers 32 and 34 are arranged above and below with a gap 36 (see FIG. 6) between their peripheral surfaces.

  The pea is inserted into the gap 36 between the pair of rollers 32 and 34 in the subsequent stage while the pod is cut by the rotation of the cutting roller 30. The pair of rollers 32 and 34 rotate in opposite directions so as to draw the peas conveyed from the belt body 14 c into the gap 36.

  As will be described later, when the peas are drawn into the gap 36, the beans in the pod are squeezed out, and only the pods are drawn into the gap and sent out to the rear side. By dropping from the front side of 36, it is possible to remove the beans from the pod. As the beans are squeezed out from inside, the pods pass through the gap 36 and are discharged from the rear side of the rollers 32 and 34 and dropped.

  The rollers 32 and 34 are made of, for example, stainless steel having a length of about 300 mm and a diameter of about 50 mm, and the peripheral surfaces are subjected to rubber lining treatment. The width of the gap 36 between the pair of rollers 32 and 34 is preferably about 0.5 mm.

  FIG. 6 is a schematic diagram for explaining the sheath peeling operation. As shown in FIG. 6A, first, the peas conveyed by the belt body 14c are advanced from the front end in the advancing direction while being cut into the sheath by the rotation of the cutting roller 30, and a pair of rollers It is drawn into the gap 36 between 32 and 34. As shown in FIG. 6 (b), when the sheath is drawn into the gap between the two rollers 32 and 34, the sheath is crushed in order from the front end portion in the advancing direction, and the sheath is cracked by the pressure. Beans are squeezed out from inside.

  In peas, the pods are harder than other beans such as edamame and broad beans, and even if the pods are simply crushed from the tip by a roller, it is found that the pods are hard to break did. On the other hand, in this invention, before drawing in the clearance gap between rollers, the process of notching a sheath is added. Thereby, a sheath becomes easy to deform | transform and a sheath comes to be cracked by the compression by a roller.

  Beans that have jumped out of the pod fall down in front of the rollers 32 and 34 in the traveling direction and are collected in a container such as a bucket placed on the gantry 10. When the beans are squeezed out, the pods are left and right with respect to the traveling direction, and jump out of the right and left sides of the pods and fall.

  Then, as shown in FIG. 6C, only the sheath is fed to the rear side of the rollers 32 and 34 and falls downward. Place a container, such as a bucket, at the position where the sheath falls, and collect the sheath.

  The present invention is not limited to the above-described embodiment, and there are design changes within a range that does not depart from the gist including various modifications and corrections that can be conceived by those who have ordinary knowledge in the field of the present invention. Of course, it is included in the present invention.

  For example, in the above embodiment, the description has been given of the configuration in which the cutting rollers make a cut on the upper surface side of the peas conveyed on the belt body. However, as shown in FIG. It is good also as a structure which arrange | positions and cuts into the both sides of the upper surface side and lower surface side of a pod while pinching a pea between two cutting rollers.
