Description

[Detailed Description of the Invention] The present invention relates to an apparatus for peeling grapes one by one.

In the past, when grapes were further processed and added to juice etc. in granular form, or to make grape jam etc., it was necessary to peel each grape one by one, but this work was mainly done by hand. That's what it used to be.

For this reason, production costs were extremely high, and as a result, only high-quality grapes were processed in this way, and the possibilities for using them as processed foods were extremely limited.

This invention was created in view of the current situation,
We have developed a device that can peel grapes, which was difficult to do mechanically in the past.

That is, its specific configuration is a running flat belt and a flat belt I.
- It is equipped with a peeling roller horizontally suspended close to the surface, and a guide plate arranged in parallel with the peeling roller at a constant interval on the front side in the running direction of the belt, and on the top surface of the belt. , an uneven strip for biting is formed obliquely with respect to the traveling direction of the belt, and the peeling roller is arranged so that its axis is substantially perpendicular to the uneven strip for biting, and its circumferential surface is A concave groove extending in the axial direction is formed in the groove.

The present invention will be explained in detail below based on the illustrated embodiments.

1 and 2 show the overall structure of an apparatus which is an embodiment of the present invention, and reference numeral 1 designates a frame formed of a suitable angle material.

A driving pulley 2 and a driven pulley 3 are provided at both front and rear ends of the frame 1, and a flat belt 4 is suspended between the driving pulley 2 and the driven pulley 3.

Incidentally, reference numeral M1 is a main motor that provides power to the drive pulley 2.

The upper surface of this flat belt 4 is not completely smooth, but is diagonal to the longitudinal direction of the flat belt 4 (approximately 45 mm in this embodiment).
In this case, grooves 5 are provided intermittently at different times.

Of course, by providing these four stripes 5, the other surface relatively protrudes from the grooved stripes 5, and when the grooved strips 5 are formed at a dense pitch, the upper surface of the flat belt 4 will have many uneven stripes. It will be formed.

Of course, instead of the grooved stripes, protruding stripes may be provided at regular intervals.

The point is that it is not just a flat surface; it is sufficient that the uneven grooves are formed diagonally.

A peeling roller 6 is horizontally suspended on the -L side of such a flat belt 4, and support plates 7 and 8 are made to project laterally from the frame 1, and bearings 9 and 10 are mounted thereon. It is attached to support the shaft 6a of the peeling roller 6.

A drive motor M2 for the peeling roller 6 is mounted on one end of the shaft 6a.

Note that this support plate 7.3 is capable of adjusting its fixing height with respect to the frame 1.
This allows the optimal position of the peeling roller 6 to be set depending on the size of the grapes to be processed, the hardness of the skin, etc.

Naturally, the peeling action is often performed at a position close to the front of the flat belt 4 in the running direction, so in the plan view shown in FIG. It is also possible to make only the support plate 8 on the side without the support plate 8 adjustable.

Further, in cases where the properties of the grapes to be treated are completely limited, it is of course possible to form them in a fixed manner in advance.

As shown in FIGS. 4 and 6, several grooves 11 are formed on the circumferential surface of the peeling roller 6, and the material of the peeling roller 6 itself is made of elastic synthetic resin or the like. It is used.

Furthermore, a guide plate 12 is attached to the frame 1 at a position along the peeling roller 6 and on the front side in the direction of movement of the flat belt 4, as shown enlarged in FIGS. 4 to 6. It is disposed in front of the peeling roller 6 at an interval approximately equal to the grain of the grape.

It is preferable that the guide plate 12 is not simply provided horizontally, but rather has a shape that is slightly bent upward at a position on the front side in the traveling direction of the flat belt 4, as shown in FIG.

Further, the distance between the guide plate 12 and the peeling roller 6 may be parallel, or may be slightly tapered.

Furthermore, a supply trough 13 is provided diagonally on the base side of the guide plate 12 (on the front side in the direction of movement of the flat belt 4), and a chute 14 that projects below the frame 1 is provided on the tip side of the guide plate 12. establish.

Further, guide plates 15 and 16 are provided to set the tip of the supply trough 13, and a skin collection chute 17 is provided in front of the flat belt 4.

Since the present invention has such a structure, when the grapes A, which have been removed from the bunch one by one, are dropped from the supply trough 13, they tend to move forward according to the movement of the flat belt 4.

However, since the peeling roller 6 is horizontally suspended in front of the peeling roller 6, the peeling roller 6 moves diagonally along the peeling roller 6, and at that time, the peeling roller 6 gets caught on the grooved line (the grooved line 5 in this embodiment) provided on the belt 4. As a result, it is pushed somewhat forcefully toward the peeling roller 6 side.

Of course, there is a guide plate 12 on the front side of the belt 4 in the direction of movement to prevent the grapes A from bouncing back, and as soon as the grapes A come into contact with the peeling roller 6 somewhat forcefully, the skins are removed. A.

Only the portion A1 is caught between the peeling roller 6 and the flat belt 4 and torn off, and the A1 portion is ejected into the chute 14 on the side thereof.

And skin A.

The person is transported on the flat belt 4, and the flat belt 4
It is dropped into a collection chute 17 provided in front.

As described above, the present invention cleverly combines a flat belt and a peeling roller to peel grapes, thereby saving labor.

Although this embodiment is the most basic one, for example, when grapes have various sizes, it is possible to combine several peeling rollers and guide plates in series with one flat belt. is set, and the grapes are guided to the optimal peeling roller for each grain size using a grading machine.
It is also possible to perform work with higher processing efficiency.
