Abstract

PURPOSE: To obtain the subject device of simple constitution carefully removing a shell from a boiled egg by reciprocating a repeatedly sliding device arranged over shell removing rollers rotating in the same direction in the axial direction of the shell removing rollers. CONSTITUTION: The shell removing rollers 16, 16... rotating in the same direction rotates a boiled egg and the sliding boards 23 and 23 of the repeatedly sliding device arranged over the shell removing rollers reciprocates the egg within a gap between the rolls. As the egg shell is removed by proper friction force between the egg shell and the shell removing rolls, the egg itself is not damaged.

2. Description of the Related Art Devices of the above type are DD-PS 61380.
Is known from

The dehulling device described in this specification comprises two dehulling rolls which are rotatable in opposite directions. Due to the opposite directions of rotation of the two unpeeling rolls (in this case the directions of rotation are directed towards each other), the objects to be shelled are drawn into the nip between the rolls, and here the rubber-like nature of the unpeeling roll Shelled by the cover.

In DD-PS 61380, the shelling device outlined above is recommended for fruits with a particularly soft hull, and to this extent its use on boiled egg shells is not excluded.

However, it is not possible to carefully dehull a boiled egg with the device described in this specification, since it is possible to remove the shell from the egg with relatively small pieces. Is not possible and there is a risk that the eggs to be shelled will be damaged in the interroll gap.

SUMMARY OF THE INVENTION The object of the invention is of the type mentioned at the outset, which is of a very simple construction and which makes it possible to carefully and completely remove the shell from the boiled egg. To find a device.

Means for Solving the Problems The means of the present invention for solving the above problems is such that a shelling roll can be driven to rotate in the same direction, and a sliding entrainment device is provided above the shelling roll. The sliding entrainment device is reciprocally movable in the axial direction of the shell peeling roll, and the egg to be shelled by the sliding entrainment device reciprocates in the roll gap formed between the two shell peeling rolls. Being able to exercise.

[0008]

The dehulling device formed as described above has a non-complicated mechanical construction, which simply requires a sliding entrainment device, except for two dehulling rolls. Because it is. Such a shelling device carefully and completely shells the boiled egg by continuously rotating the egg between the two shelling rolls and at the same time reciprocating the roll gap. During these movements, the proper friction between the egg shell and the unhulling roll provides a complete removal of the egg shell without damaging the boiled egg itself. The egg shell falls through the interroll gap and can then be removed by any method.

A particularly simple construction of the sliding entrainment device comprises two sliding plates which are spaced apart from one another.

It is advantageous if the sliding plates are inclined in the same direction with respect to the vertical plane so that they form a channel which expands in the direction of the peeling roll.

Due to the tilted position of the two sliding plates in the above sense, a constant crimping of the eggs to be shelled on the shells to be shelled during the reciprocating movement of the eggs in the gap between the shelling rolls is obtained. The shelling process is additionally accelerated.

Further features of the invention are set forth in the other claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 schematically shows a device for shelling boiled eggs. The device comprises a machine stand 10, which stands on four legs 11. The device is equipped with a circulating chain transmission 12, which is the chain transmission 1.
It consists of three and two turning guide chain cars 14,15. In FIG. 1, the deflection guide chain wheels 14 and 15 can be driven in the counterclockwise direction indicated by the arrow A.
The drive is not shown for convenience.

The chain 13 has a large number of peeling rolls 16
(Details will be described later) are arranged, and these peeling rolls are located at a slight mutual interval. Another chain transmission 17 is provided above the chain transmission 12 above.
Are arranged so that the peeling roll 16 is rotated. Peeling roll 16 as shown in FIG.
The direction of this rotation of the wheel coincides with the direction of rotation of the deflection guide chain wheels 14, 15 of the chain transmission 12. The eggs to be shelled are fed on the right side of the chain transmission 12 in FIG. 1 and, on the left side, the method is not described in detail. For convenience the egg is implicitly written as a circle and has the code 1
Shown at 8. A shelling roll 16 assigned to the upper side of the chain transmission 12 forms a horizontal shelling section for the eggs 18.

The drive for the peeling roll 16 is shown in more detail in FIG. It shows that each shelling roll has a consistent shaft 19 and a cover 20 made of rubber or rubber-like plastic, in which case the whole shelling roll has a high coefficient of friction, especially in combination with an egg shell. It must be mentioned that it can be made from a substance having

In order to rotate the peeling roll 16, two rows of chain wheels 21 are arranged on the right side of the shaft 19, that is, on the side opposite to the cover 20, so that they cannot rotate relative to each other. Above the chain wheel 21, the underside of the chain transmission 17, which engages all the chain wheels of the peeling roll, circulates. Therefore, the peeling roll 16 is driven exclusively when the chain wheel 21 is located within the meshing range of the chain transmission 17. This is when the peeling roll 16 is in the upper area of the chain transmission 12.

From FIG. 2 it is clear that a sliding entrainment device 22 is arranged above the unhulling roll 16. The sliding drive comprises two sliding plates 23 which are preferably arranged at a distance from one another, which sliding plates are fixed to a carrier or a holder 24. The holder 24 is connected to the crank drive device 25 and can reciprocate in the direction indicated by the arrow B. In this case, of course, the sliding plate 23 fixed to the holder 24 can also reciprocate.

The sliding plates 23 are mutually inclined in the same direction with respect to the vertical plane, so that the two sliding plates 23 form a passage which expands toward the peeling roll 16. The two end positions of the two sliding plates 23 during the reciprocating movement are shown by the one-dot chain line in FIG. The inner spacing between the two sliding plates 23 corresponds to at least the length of the eggs to be shelled.

As can be seen from FIG. 2, the peeling roll 16
Place several eggs side by side on this peeling roll 16,
And it has a length that can be peeled. To this end, a plurality of sliding plates 23 arranged in pairs are provided above the shelling rolls 16, whereby various "shelling channels" are provided for the plurality of eggs 18 arranged side by side. Are formed. In the illustrated embodiment, four peeling mechanisms are arranged side by side. As can be seen in FIG. 1, the eggs to be shelled are each fed between two shelling rolls 16. The egg is continuously rotated between these two unhulling rolls 16 and, at the same time, is reciprocally moved in the axial direction of both unhulling rolls by the sliding plate 23. This movement completely separates the boiled egg shell from the boiled egg, but in this case the length of the upper transport section of the chain transmission 12 ensures that the eggs to be shelled are well separated between the two hulling rolls. Long stay time is guaranteed.

Due to the possibility of arranging several dehulling sections or dehulling mechanisms side by side, the device of the construction according to the invention can be designed with a high dehulling efficiency and, for that reason, a complex mechanism is required. There is no such thing.

The peeling roll 16 may be provided with knots or protrusions if necessary.
