FR2662913A1 - Device for making slight incisions for bakery use - Google Patents

Abstract

The invention relates to a device for making slight incisions for bakery use. It is made up of a support comprising a rectangular frame of elongate shape (8) which can be located above the portion of bread in which slight incisions are to be made. A double-acting cylinder (1) is secured to a vertical plate (4), whilst its driving rod (7) is, in turn, secured to an arm (9) carrying cutting blades (10) located parallel to the major sides of the frame. The driving rod (7) cannot pivot during its linear displacement obliquely with respect to the frame (8) owing to a guide ring (6) which slides along a bar (5) parallel to the rod. The frame (8) is connected to the support by means of a piece (13) which allows it to tilt and, in doing so, a switch (11) brings the cylinder (1) into action so that the blades (10) can cut inside the frame (8) obliquely.

Description

 The invention relates to a scarification device for a bakery.

 Its purpose is to produce shallow incisions in portions of bread dough about to be submitted to cooking, to cut the surface of the dough formed, so that it opens while baking in the oven.

 The use of scarifiers in the production of bread is widely known, from the primitive cutting edge with which skilful cuts were made by hand, and to the various sophisticated devices simultaneously producing the three classic diagonal cuts, a long way was traveled without the ideal solution having ever been found.

In the prior art, various methods are applied to scarify the bread dough. We can mention
European Patents numbers 8400657 and 8703082, as well as
Registered models 222 264; 265,525; 275,150; 221,614 and 263,523 among others.

 In all the cases indicated, more or less complicated mechanisms are used to make the cuts in question.

The greatest difficulty they present consists in
The fact that said cuts do not occur at the ideal location, because the arrangement of the cuts is also a function of the position of the bread dough as it passes through the device.

 Under these conditions, the quality of the bread produced is considerably reduced from the point of view of its presentation.

This is why we continue to use manual scarification, with the consequent economic damage that this entails.

 In order to solve the problems mentioned, the invention provides a device with semi-automatic operation, that is to say, applied manually to the piece of shaped dough, in contact with which then comes into operation the blade holder which produces scarification .

It comprises a support structure, having gripping means for its handling, and constituted by a plate to which is attached a double-acting cylinder, the drive rod of which comprises a blade-carrying arm and a guide element sliding along a bar fixed to the support structure. This support structure is composed of a frame in the form of a rectangular frame, the major sides of which are
Slightly arched.

 The frame is located in a diagonal position with respect to the cylinder rod and, during their movement of movement, the cutting blades follow direction lines which cut diagonally the aforementioned frame, so that the frame is placed on a workpiece of extended bread dough, the blades scarify the dough in the diagonal direction indicated.

The cylinder is put into operation by
The action of a mercury switch and by a magnet, acting so that The action of the cylinder in the direction of cutting occurs When the frame comes into contact with the portion of dough, and its immediate recoil to the position cycle start occurs as soon as the device is raised.

 The accompanying drawings for a better understanding of the object of the invention show it in two positions.

 Figure 1. Plan view of the device in the rest position.

 Figure 2. Perspective to see its functionality.

 As can be seen in the above drawings, the device comprises a double-acting cylinder (1), as a support element and for its handling, provided with two connections (2) and (3). A handle or handle (not shown) can be added. The cylinder is integral with a plate (4) in the upper part of which is embedded a bar (5) provided with a ring (6) in turn sotidaire The drive rod (7) of the cylinder. The support includes a rectangular frame-shaped frame (8) whose major sides are slightly arched, even if they appear straight in the drawing. This frame is placed in a diagonal position relative to the theoretical axis of the cylinder (1) and its rod (7). This rod (7) has an extension formed by an arm (9) which is parallel to the two major sides of the frame and which supports a series of blades (10) arranged diagonally to the arm (9) and therefore relatively to the sides of the frame.

 The displacement of the rod (7) of the cylinder causes the blades to advance diagonally relative to the frame.

 If, when the device is used correctly, the frame is positioned on a piece of bread dough located in its frame, the advancement of the rod (7) as well as the Blades (10) will produce scarification by means of shallow cuts in the mass, all parallel and in the same direction.

 This forward movement is produced by the action of a mercury switch (11) in combination with a magnet (12), producing the engagement of the cylinder by cutting the circuit when contacting the frame (8) with the mass of dough, which causes a slight pivoting relative to an anchor point (13) and opposite the support plate.

Raising the device reverses the position of
The switch by its own weight, on which the cylinder reacts by recovering the blade support.

Claims (1)

 CLAIM  DESCARIFICATION DEVICE FOR BAKERY, having a blade support acting simultaneously to produce superficial parallel cuts on a portion of bread dough, and characterized in that it comprises a support element for its manual application, formed by a cylinder (1) double-acting, of which a vertical plate (4) is integral, on the upper part of which is assembled a bar (5), parallel to the drive rod (7) of the cylinder, bar in which a ring is threaded ( 6) integral with said rod (7), said bar serving as a guide for the rod itself, and a support proper comprising an elongated rectangular frame (8) with dimensions little larger than a piece of bread, placed in position diagonal to the cylinder, and which is in relation to said support element by means of a part (13) allowing it a certain rocking movement for the actuation of a mercury switch (1 1) combined with a magnet (12) with which the cylinder is actuated, the drive rod (7) of which is secured to an arm (9) parallel to the major sides of the frame (8), and which supports several blades which, moving, follow diagonal lines and cut The inside of the frame as soon as it comes into contact with the mass of dough and the switch is on.
