Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a peeling head device for a fruit processing machine that automatically peels, cores, and divides substantially spherical fruits in a continuous manner.

<Prior Art> The inventor previously proposed a new fruit processing machine for peeling fruits, especially apples, pears, etc. (Special Publication No. 52-2 Tade μ, Patent No. G7 De Otsu No. 12).

In the invention of this earlier application, while rotating the fruit, a peeling blade is lightly pressed against the outer surface of the fruit to thinly peel the outer skin, and the skin is further divided into a predetermined number of pieces. Equipped with a pair of peeling blades, I was able to work quickly and continuously with great results.

The peeling head device in the above invention is formed of an arm fixed to a drive shaft perpendicular to the axis of rotation of the fruit, and a peeling blade biased inward at the tip of the arm. It applied light pressure to the outer surface of the rotating fruit, moved in an arc, and continuously peeled off the outer skin of the fruit.

<Problems to be Solved by the Invention> However, with this peeling head device, the contact angle between the skin and the blade changes depending on the size of the fruit and local unevenness on the outer surface, resulting in local peeling. There were problems in that some parts of the fruit remained unpeeled, and part of the pulp was scraped off due to too much digging.

Furthermore, the length of the peeling head device, which rotates, is limited in order to avoid contact between its tip and the fruit holding needle or the fruit center removing/dividing blade.

Therefore, there is a problem in that the blade portion and the fruit cannot come into contact with each other at the optimum contact position, that is, at the maximum outer diameter line as seen from the peeling head device.

Means for Solving the Problems The present invention has been made in view of the above points, and provides a peeling head device for a fruit processing machine that moves in an arc around the outer circumference of a rotated fruit to peel the outer skin of the fruit. The peeling head device includes a cam fixed to the machine base, a rotating member that rotates facing the cam, and an arm structure that is pivotally supported by the upper rotating member and follows the rotation of the cam β, The arm structure includes a driven member that is pivotally supported by the rotating member and includes a rolling contact roller and a tilting roller that roll in contact with the cam, and an arm that is hinged to the driven member and urged inward. and a cutter head disposed at the tip of the arm so as to be able to swing vertically, horizontally, and horizontally, and the arm structure has a side in contact with the cam that is biased in the rotating direction. A peeling head device for a fruit processing machine, wherein the structure is configured to be tilted in a predetermined position as a result of the movement on the arm.

Hereinafter, the configuration of the present invention will be explained based on the drawings.

Move the outer periphery of the rotated fruit M in an arc shape to remove the outer skin 3
In the peeling head device of the peeling fruit processing machine, the peeling head device includes a cam 23 fixed to the machine base 1 and a cam 2.
The arm structure 7 is composed of a rotating member 3 that rotates facing the rotating member 3 and an arm structure 7 that rotates and follows the cam 23 that is pivotally supported by the rotating member 3. a driven member 8 which is pivotally supported by the cam 2 (3) and includes a rolling contact row 'y10 and a tilting roller 9 that come into contact with the cam 2 (3) and a tilting roller 9; an arm 13 that is hinged to the driven member 8 and is biased inward; The arm 13 is provided with a cutter head 15 disposed at the tip thereof so as to be able to vertically and horizontally swing, and the side of the arm and structure 7 that contacts the cam 23 is biased in the rotational direction as described above. The arm structure 7 is configured to be tilted at a predetermined position as it is driven by the cam 23, and the fruit M and the cutter blade portion 21a are brought into contact with each other at the maximum outer diameter line P of the fruit M when viewed from the peeling head device. The cutter head 15 follows the local irregularities on the outer surface of the fruit M by moving up and down and swinging left and right freely, and the contact between the cutter and the skin of the fruit is not affected by the angle of depression of the arm 13 depending on the size of the fruit. This is a peeling head device for a fruit processing machine that always maintains the tangent angle at an appropriate angle.

Function> Next, the function of the peeling head device when the peeling head device is installed in a fruit processing machine will be explained based on FIG. 1 to FIG.

A fruit holding needle K of a fruit processing machine is inserted into the fruit Md, which is a workpiece, and its shaft U, and is held in a predetermined position. The peeling head device is installed at a predetermined position of the fruit processing machine, that is, facing the fruit M, and with the rotation axis U of the arm structure 70 orthogonal to the fruit holding needle K.

At this time, the rotating member 3 is oriented substantially directly above the arm structure 7.
is in an upright state on the cam 23, and the blade portion 21a of the cutter 21 at its tip is elastically and lightly pressed against the outer skin of the fruit M on the maximum outer diameter line P of the upper part.

When the fruit holding needle starts rotating (in the direction of arrow S in Figure 1), the drive shaft 2 connected to the power of the fruit processing machine starts rotating in a predetermined direction (in the direction of arrow Q in Figure 1). .

As the drive shaft 2 rotates, the rotating member 3 follows and rotates on the rotating surface T.
The arm structure 7, which rotates as shown in FIG.

In arm configuration #-7, the contact side of the cam 23 is biased in the rotational direction (in the direction of arrow R in FIG. 1), and the biasing force causes the rolling contact roller 10 to contact the lower portion 23a of the cam 26. The tilting roller 9 maintains a slight lifting gap G with respect to the surface of the lower portion 23a.

When the arm structure 7 rotates, the cutter 21 moves on the maximum outer diameter line P of the skin of the fruit M from the top to the bottom.

At this time, the cutter head 15 moves up and down and moves left and right independently of the depression angle due to the inward biasing force of the arm 13.
The contact between the cutter 21 and the skin of the fruit M is always maintained at a predetermined angle by freely following the local irregularities on the outer surface of the fruit M and the size of the fruit M.

The biasing force in the direction of arrow R acting on the arm structure 7 described above is caused by the biasing force on the left side of the arm structure 7 that occurs when the frictional force between the cutter 21 and the fruit M becomes uneven on the left and right sides during the peeling operation. Shake in the direction? is being prevented.

In this way, the cutter 21 draws an arcuate trajectory 3 and cuts the fruit M.
Reaching the bottom, the peeling work is completed. .

Immediately after the peeling operation is completed, the tilting roller 9 of the arm structure 7 comes into contact with the stepped portion 23b of the cam 23. (Fig. A
(See) The arm structure 7 is driven around the pivot portion 5a, and its tip portion is tilted in the rotation direction.

Therefore, even if the dividing blade for removing and dividing the fruit M which is performed after peeling the fruit M rises from below the fruit M, the arm structure 7 and the dividing blade will not come into contact with each other. Avoided.

Furthermore, with the rotation of the rotation member 3, the tilting row 'y9 moves towards the cam 2.
3. The arm structure 7 rolls on the high position part 230 (see Figure B), and the arm structure 7 rotates in a tilted position. At this time, the rolling contact roller 10
is away from the high-order portion 230 surface.

Further, the rotating member 3 rotates, and the tilting row '79 engages the cam 23.
When reaching the slope portion 23d, the distance between the rotating surface T of the rotating member 3 and the contact point of the tilting roller 9 gradually increases, and the arm structure 7, which is biased in the direction of the arrow hole, rotates. As it moves, it gradually rises on the cam 23. (Figure C
(Refer to) When the rotation further progresses and the rolling contact roller 10 enters the slope portion 23d, the rolling contact roller 10 contacts the slope portion 23d surface and is driven, and when the rolling contact roller 10 contacts the lower portion 23a. ,
The arm structure 7 is in an upright state, and the tilting roller 9 maintains a gap G with the surface of the lower part 258 (see the ≠ diagram), and the / cycle process is completed and the next peeling start position is assumed.
