Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grape peeling machine that can automatically peel grapes.

[Prior art and its drawbacks]

Grapes are used in various sweets and juices with their skins peeled, so they must be peeled beforehand. However, since the size, shape, softness, etc. of each grape vary slightly, it has been difficult to peel them automatically using mechanical force.

However, recently it has been proposed to perform peeling using mechanical force with a structure as shown in Figures 3 and 4.
Some of them have been put into practical use. This peeling machine consists of two rolls 01 and 01' with knurling cut on their surfaces, arranged vertically in parallel with a small gap between them, and rotated in opposite directions. A chain 02 running downward along the center of
The grapes are introduced into the triangular space 03 created by the chain 02, and the speed of the grapes falling is controlled by the chain 02, and the grapes are pressed between the rolls 01 and 01' by knurling cut into the surface of the rolls 01 and 01'. The surface of the skin is peeled off by the action of the rollers 01 and 01', and the skin is discharged backward through the gap between the rolls 01 and 01', and the peeled grapes are discharged downward. Also, during the peeling process, water is constantly supplied from the water supply port 04 to improve the flow of the grapes. However,
The conventional peeling machine described above has the following drawbacks.

a. Since the force with which the chain 02 presses the grapes against the rolls 01 and 01' differs depending on the size of the grapes, small grapes are discharged without being peeled.

Therefore, in the past, it was necessary to prepare the grapes to a uniform size in advance, which was a labor-intensive process, and small grapes were thrown away because they could not be machined, resulting in a lot of waste. In addition, even if the grain size is kept constant in this way, around 10 to 20% of unpeeled grains will still be mixed in.
It takes a lot of time to sort these out from the peeled ones.

b Rolls 01 and 01' have knurling cuts to make the skin catch better.
If slightly larger grains enter, the pressure exerted by the chain 02 becomes stronger, damaging not only the skin but also the meat, resulting in a significant decrease in commercial value. This problem occurs not only due to the size of the grains but also when the grains are soft.

c Chain 02 according to the size of the grapes.
It is necessary to set the distance between the rollers 01 and 01', and this adjustment takes time and effort.

[Purpose of this invention]

This invention is proposed in view of these points,
The purpose is to propose a grape peeling machine that can perform 100% peeling regardless of the size of grapes and does not damage the pulp.

[Structure of the present invention and its function]

In order to achieve the above object, the present invention proposes a grape peeling machine having the following configuration.

A roll device comprising two rolls arranged in parallel with a slight gap and arranged with a downward slope, an endless chain that runs downward along the rolls between the rolls in the roll device, and this endless chain. A chain device comprising a drive chain wheel positioned above the roll and an idling chain wheel positioned below for driving the roll device; A grape peeling machine comprising: a drive device for rotating a drive chain wheel of the chain device;

In the peeling machine described above, the rolls of the roll device rotate in opposite directions, and the chain of the chain device runs downwards along the rolls by an upper drive chain wheel. In this state, when grapes are fed one by one between the inclined rolls and above them, the grapes are arranged in a line within the triangular space formed by the rolls and the chain, and then into the chain. The grains enter the grains at regular intervals and move as they roll on the roll. During this rolling movement, the grains are pressed against the roll by the chain and their skins are peeled off on the roll surface. Then, the skin is discharged to the rear (downward) of the roll, and the grains roll further and come out from below and fall into the product receiving basket.

In the above-mentioned peeling operation, since the chain has its driving chain wheel on the upper side and the idle chain wheel on the lower side, the tension on the chain is applied to the return side, that is, the upper side, and is not applied to the roll side. As a result, a sag occurs in the chain running on the roll side, and if the grain is large, it will escape to the opposite side of the roll due to the action of this sag, and if it is small, it will move closer to the roll side, depending on the size of the grain. It presses the grapes evenly and ensures that the skins are peeled.

[Examples and their effects]

An embodiment of the present invention will be described in detail below based on the drawings.

In FIG. 1, numeral 1 indicates a roll device,
This roll device 1 has two rubber rolls 2 and 2a with smooth surfaces arranged in parallel with a small gap between them, and the rolls 2 and 2a are rotated by a drive device 3 in directions facing each other as shown by arrows a in FIG. It is designed to do so.

4 is a chain device disposed on the roll device 1, and this chain device 4 has a driving chain wheel 6 positioned above the roll device 1 and an idling chain wheel 7 positioned below;
The chain 5 has a configuration in which the chain 5 is stretched between the chain foils 6 and 7, and the chain 5 is located at a distance between the rolls 2 and 2a, and gradually moves from the top to the bottom toward the rolls 2 and 2a. The drive device 3 causes the rollers to run clockwise as shown by arrow b, that is, from above to below the rolls 2, 2a.

In the figure, 8 is a grape supply hopper, 9 is a water supply port that supplies water along the rolls 2, 2a, 10 is a product receiving basket placed below the rolls 2, 2a, 1
1 is a leather basket.

The best inclination of the rolls 2, 2a is about 30 degrees. Further, although a metal chain is used in the embodiment, a plastic chain may be used instead of this, or an endless belt may be used instead of the chain.

Next, the operation of the above-mentioned peeling machine will be explained.

The rolls 2, 2a of the roll device 1 are rotated in the direction of arrow a in FIG. 2 by a drive device 3, and the chain 5 of the chain device 4 is rotated in the direction of arrow b by a drive chain wheel 6. When grapes P are supplied from the hopper 8 in this state, the grapes P enter the triangular space c formed by the rolls 2, 2a and the chain 5 one by one and are unified by the chain 5. The spacing between grains is regulated, and the grains are moved to rolls 2 and 2 by the sagging action of chain 5.
It rolls and moves on the rolls 2 and 2a while being pressed to the a side. During this movement, the rolls 2 and 2a rub the surface of the grapes P, and this action causes the skins to peel off, and the peeled skins are discharged from the back side of the rolls 2 and 2a to the skin receiving basket 11, and the peeling is completed. Grains of ivy P are discharged from the lower ends of the rolls 2, 2a into the product receiving basket 10.

[Effects of this invention]

In the present invention, the rolls are tilted as described above, and the drive chain wheel is positioned above the rolls (grape supply side) so that the chain running along the rolls sag, resulting in the following effects. You can expect it.

a The grapes move while rolling on the rolls, and the sag of the chain pushes the grapes against the rolls, so they are pressed evenly regardless of their size.

As a result, all grains are peeled regardless of their size, so there is no need to prepare the grains in advance, discard small grains, and waste time and effort in sorting out the grains with the skin still attached from the product. disappears.

b. The grapes roll on the rolls, and the sag of the chain presses the grapes against the roll surface, so there is no need to cut knurls on the roll surface to bite into the skin and improve rubbing.

As a result, since the skins are not forcibly peeled, the pulp is not damaged, and peeled grapes with high commercial value can be supplied.
