Description

  The present invention relates to a shelling machine used for peeling peanut shells.

Conventionally, as foods produced from peanuts, foods obtained by frying peanut strips with oil, foods obtained by roasting peanut strips, and the like are known. All of these foods require peanut shells to be peeled off during the manufacturing process, and this operation is laborious. Therefore, a machine capable of peeling peanut shells is required.

Therefore, for example, Patent Document 1 discloses a molting machine for molting seeds such as soybeans. This molting machine includes a low-speed rotating body and a bellows-like high-speed rotating body that rotates at a higher speed than the low-speed rotating body. In this molting machine, the seed that has been water-expanded is conveyed to the adjacent portion between the low-speed rotating body and the bellows-like high-speed rotating body by the rotation of the low-speed rotating body. When seeds are transported to the adjacent part, the difference in rotational speed between the high-speed rotating body and the low-speed rotating body acts as a twisting stress, or the seeds are rubbed by the elastic body covering the outer periphery of the bellows-like high-speed rotating body. By doing so, seed molting is performed.

Then, peanuts are put into the hopper 4 to put peanuts into the gap S, and the inner cylinder 2 is rotated around the axis G using the handle 51.

FIG. 11 is a view showing a locus K along which the peanut R moves in the gap S (FIG. 11A is a plan view showing the outer peripheral surface 2a of the inner cylinder 2, and FIG. It is sectional drawing which cut | disconnected the outer cylinder 3 in the surface which follows. The peanut R that has entered the gap S is pushed downward by the following peanuts existing on the upper side thereof, and is pushed around the axis G by the rotation of the inner cylinder 2. As a result, the peanut R descends spirally in the gap S as shown by the locus K shown in FIG. And the 1st hole 10 (FIG. 4) formed in the outer peripheral surface 2a of the inner cylinder 2 is extended in the up-down direction, and a part of the peanut descending spirally in the gap S is in the first hole 10. Each time it is fitted, the orientation is corrected so that the longitudinal direction extends in the vertical direction.

And since the width | variety of the clearance gap S becomes so narrow that the peanut R which descend | falls spirally in the clearance gap S fits into the clearance gap S in any position of the clearance gap S arises. At this time, the outer surface of the peanut R is strongly rubbed against the outer peripheral surface 2 a of the inner cylinder 2 in which the first hole 10 is formed and the inner peripheral surface 3 a of the outer cylinder 3 in which the second hole 11 is formed. Thereby, the shell Ra of the peanut R is peeled off, and the size of the peanut R is reduced. Then, the peanut R having a reduced size further descends spirally in the gap S, so that the peanut R fits into the gap S again. At this time, the outer peripheral surface 2a of the inner cylinder 2 in which the first hole 10 is formed and the second hole 11 again.
When the peanut R is rubbed strongly against the inner peripheral surface 3a of the outer cylinder 3 on which the peanut is formed, the shell Ra remaining on the peanut R is peeled off, and the size of the peanut R becomes smaller ((A in FIG. 11 is peanut) R indicates the position of the gap S that fits first, and B, C, and D in FIG. 11 show the position of the gap S in which the peanut R that has been reduced in size due to peeling of the shell is fitted. In the form of shelling machine 1,
Since the gap S is narrower toward the lower side, it is repeated that the peanut R fits into the gap S and the peanut R is rubbed strongly against the inner cylinder 2 or the outer cylinder 3 in the process of the peanut R descending spirally in the gap S. As a result, the shell Ra of the peanut R is gradually peeled off. Then, the peanut body Rb from which the shell Ra is peeled and the shell Ra peeled from the peanut R descend in a spiral manner in the gap S to reach the lower end of the gap S and fall from the lower end of the gap. Of the shell Ra peeled from the peanut R, the shell Ra having a size smaller than the first hole 10 passes through the first hole 10 and enters the inside of the inner cylinder 2, and falls inside the inner cylinder 2.

An upper chute 60 (see FIGS. 1 and 2) extending obliquely downward is provided below the gap S and the inner cylinder 2. The peanut body Rb and shell Ra that have passed through the gap S and the shell Ra that has passed through the inner cylinder 2 fall on the upper chute 60. Peanut R falling on the upper chute 60
The body Rb and the shell Ra are collected in a first container (not shown) disposed outside the carriage 7 by sliding along the upper chute 60. The upper chute 60 includes a main body portion 60 a that is suspended from the upper wall 7 c of the carriage 7 and an outer portion 60 b that is disposed outside the carriage 7. The main body 60a extends obliquely downward from a position immediately below the gap S or the inner cylinder 2, and the outer portion 60a.
b is rotatably attached to the tip of the main body 60a. When the shelling machine 1 is used for shelling peanuts, the outer part 60b is tilted downward with the tip of the main body part 60a as a fulcrum. Thereby, the body Rb and the shell Ra of the peanut R falling on the main body 60a from the gap S and the inner cylinder 2 slide along the main body 60a and the outer side 60b, and the first container (not shown). )
To be recovered. When the shelling machine 1 is not used, the outer portion 60b is inverted with the tip of the main body 60a as a fulcrum (the state shown in FIG. 1).

A through hole 61 (see FIG. 1) is formed in the main body 60a of the upper chute 60.
A lower chute 62 is provided below the main body 60a. The lower chute 62 extends obliquely downward substantially parallel to the main body 60a, and is suspended from the side edge of the main body 60a. From the above configuration, the shell Ra smaller than the through hole 61 among the shell Ra sliding on the main body 60 a passes through the through hole 61 and falls on the lower chute 62. The shell Ra dropped on the lower chute 62 is recovered along the lower chute 62 by being slid into a second container (not shown) arranged outside the cart 7.

In the upper chute 60 and the lower chute 62, through holes are formed at positions on the axis G, and guide pipes 63 (FIG. 2) are passed through the through holes of the chute 60 and 62. The guide pipe 63 extends in the vertical direction along the axis G, and the gap adjusting means 6
The shaft body 30 is passed through the guide pipe 63.

As described above, according to the shelling machine 1 of the present embodiment, peanuts are introduced into the gap S,
By rotating the inner cylinder 2 around the axis G, peanuts descend in a spiral in the gap S. And since the width | variety of the clearance gap S becomes so narrow, even if various peanuts from which a magnitude | size and a shape differ are put in the clearance gap S, each of the peanuts is on the path | route where each peanut descends helically. There is a position of the gap S to be fitted. At the position of the gap S, peanuts fall on the outer peripheral surface 2a of the inner cylinder 2 and the outer cylinder 3
The inner peripheral surface 3a is rubbed strongly. Therefore, according to the shell peeling machine 1 of this embodiment, various peanut shells having different sizes and shapes can be peeled off.

Further, according to the shelling machine 1 of the present embodiment, the first hole 10 formed in the outer peripheral surface 2a of the inner cylinder 2 is long in the vertical direction, so that the peanut that descends in the gap S spirally is Part of the first hole 10
Each time it is fitted, the orientation is corrected so that the longitudinal direction extends in the vertical direction. Therefore, since the whole length of the peanut can be rubbed strongly against the inner cylinder 2 or the outer cylinder 3, the shell can be peeled over the entire length of the peanut.

Moreover, according to the shelling machine 1, the clearance adjustment means 6 is provided, whereby the width of the clearance S can be adjusted according to the size and shape of peanuts. For this reason, the peanut with a shell can be smoothly put into the gap from the upper end of the gap S, and the peanut with the shell peeled can be smoothly put out from the lower end of the gap. In addition, peanuts are classified into large balls, medium balls, and small balls depending on the size, and the grade height is large balls> middle balls> small balls. Therefore, the upper end of the gap S is set to a width that allows the shelled large ball to enter with a little space, and the lower end of the gap S is the width that allows the average size of the shelled large ball to come out without difficulty. It is preferable that

In order to surely peel the peanut shell, it is preferable to increase the number of times that the peanut fits into the gap S and is rubbed against the inner cylinder 2 or the outer cylinder 3 as much as possible. It is preferable to make the moving distance as long as possible. For example, when the dimensions of the inner cylinder 2, the outer cylinder 3, and the gap S are set as shown in Table 1 below, the amount of peanuts put into the gap S per unit time, the inner cylinder 2 and the outer cylinder 3 by rotating relative rotation speed around the axis G (rotation speed around the axis G of the inner cylinder 2 in the above embodiment) and the like, by rotating the peanuts 2-4 times in the gap S, The horizontal movement distance of peanuts can be set to 1,382 mm to 2,764 mm. In this case, the difference between the width of the upper end of the gap S and the width of the lower end of the gap S (12 mm)
Divided by the horizontal movement distance of peanuts (1,382 mm to 2,764 mm) is 1/115.
At a very small distance of ~ 1/230, at a horizontal movement distance of 1,382 mm to 2,764 mm,
Since the gap S is very narrowed, the peanut shell can be reliably peeled off.

In addition, this invention is not limited to what is shown in the said embodiment, A various modification | change is possible.
For example, the shelling machine of the present invention can be modified as shown in FIGS. 12 and 13 (FIG. 12 is a front view showing a shelling machine 70 according to a modified example of the present invention. It is a side view which shows the shell peeling machine 70 which concerns on the modification of invention. In FIG. 12 and FIG. 13, for convenience of explanation, portions that are actually hidden by other members are also indicated by solid lines as appropriate.

In the above embodiment, the handle is used as the rotating means 5 for rotating the inner cylinder 2 around the axis G. However, in the shelling machine 70 of the modification shown in FIGS. 12 and 13, the inner cylinder 2 is rotated around the axis G. A motor 71 is provided as a rotating means for rotating the motor.

Also in the shelling machine 70 shown in FIGS. 12 and 13, the outer cylinder 3 is stationary and the upper end of the inner cylinder 2 is closed by the top wall 9. The motor 71 is disposed below the inner cylinder 2 and includes a rotating shaft 72 and a motor main body 73. The rotary shaft 72 extends in the vertical direction along the axis G, and the upper end is connected to the top wall 9 of the inner cylinder. The motor main body 73 rotates the rotation shaft 72 around the axis G, and the inner cylinder 2 also rotates around the axis G along with the rotation of the rotation shaft 72.

In the shelling machine 70 shown in FIGS. 12 and 13, the rotating shaft 72 of the motor 71 also serves as the shaft body (corresponding to the reference numeral 30 in FIG. 2) of the gap adjusting means 6. That is, in the shell peeling machine 70, the lower end of the rotating shaft 72 is supported by the table 31, and the lifting mechanism 32 raises and lowers the table 31, whereby the width of the gap S can be reduced and enlarged.

According to the shelling machine 70 described above, the inner cylinder 2 can be rotated by the power of the motor, so that there is no need to manually rotate the inner cylinder 2. Therefore, the labor required for shelling can be reduced. 1 to
Similar to the shell peeling machine 1 shown in FIG. 4, the shell peeling machine 70 shown in FIGS. 12 and 13 is also provided with a guide pipe 63 (FIG. 12) penetrating the upper chute 60 and the lower chute 62, and a motor 71. The rotation shaft 72 is passed through the guide pipe 63.

In the above-described embodiment, an example in which peanuts are put into the gap S using the hopper 4 has been described. However, the hopper 4 may be omitted and peanuts may be put into the gap S from the upper end of the gap S. In this case, since the hopper 4 is omitted, the manufacturing cost of the shell peeling machine 1 can be suppressed at a low cost. As shown in the embodiment, if the hopper 4 is used, it is not necessary for the worker to stay in the vicinity of the shelling machine at all times in order to put peanuts in the gap S. For this reason, labor can be reduced.

In the above embodiment, the outer cylinder 3 is stationary and the inner cylinder 2 rotates about the axis G. On the contrary, the inner cylinder 2 is stationary and the outer cylinder 3 is fixed. May be rotated about the axis G. Alternatively, both the inner cylinder 2 and the outer cylinder 3 may be rotated around the axis G at different speeds, or the inner cylinder 2 is rotated to one side around the axis G and the inner cylinder 2 is rotated to the other side around the axis G. It may be rotated. Even in the above-described manner, the inner cylinder 2 and the outer cylinder 3 can be relatively rotated around the axis G, so that the peanuts are spirally lowered in the gap S so that the inner cylinder 2 and the outer cylinder 3 The peanut shell can be peeled off by rubbing against it. When the outer cylinder 3 is rotated around the axis G, for example, a protrusion extending around the axis G is formed at the lower end of the outer cylinder 3, and a groove extending around the axis G is formed on the upper surface of the upper plate 7c of the carriage 7. Is formed, and the protrusion of the outer cylinder 3 and the groove of the upper plate 7c are fitted. A handle is attached to the outer surface of the outer cylinder 3, and the outer cylinder 3 is rotated around the axis G using this handle. Contrary to the above, a groove extending around the axis G is formed at the lower end of the outer cylinder 3, and a protrusion extending around the axis G is formed on the upper surface of the upper plate 7c, so that the grooves of the outer cylinder 3 and the upper plate 7c The protrusion may be fitted.

Moreover, in the said embodiment, although the 1st hole 10 formed in the inner cylinder 2 was made into the hole which penetrates the inner cylinder 2, the 1st hole 10 of the inner cylinder 2 is made into the outer peripheral surface 2a of the inner cylinder 2. The dent formed may be (that is, the first hole 10 of the inner cylinder 2 may not penetrate the wall of the inner cylinder 2).

Moreover, in the said embodiment, although the 1st hole 10 formed in the inner cylinder 2 was a thing long in an up-down direction, the 2nd hole 11 formed in the internal peripheral surface 3a of the outer cylinder 3 is a thing long in an up-down direction. The first hole 10 and the second hole 11 may be long in the vertical direction.

Moreover, although the outer cylinder 3 showed the example comprised from the inner layer body 13 and the outer layer body 14 in the said embodiment, the outer cylinder 3 may be comprised from a single member.

Moreover, in the said embodiment, it is a cylindrical shape whose outer diameter becomes large, so that the inner cylinder 2 becomes lower side, and the outer cylinder 3
14 shows an example in which the inner diameter becomes larger as it goes down, but like the shelling machine 80 of the modification shown in FIG. 14, the inner cylinder 2 has a cylindrical shape whose outer diameter becomes larger as it goes up, The outer cylinder 3 may have a cylindrical shape with an inner diameter that increases toward the upper side (in FIG. 14, for convenience of explanation, a portion that is actually hidden by other members is also indicated by a solid line as appropriate). Even in this case, if the inclination angle θc of the outer peripheral surface 2a of the inner cylinder 2 with respect to the horizontal plane is made larger than the inclination angle θd of the inner peripheral surface 3a of the outer cylinder 3 with respect to the horizontal plane, the gap S becomes smaller as the width becomes lower. . Therefore, various peanut shells having different sizes and shapes can be peeled off.

In the above embodiment, the width of the gap S is adjusted by the gap adjusting means 6.
