DOUGH DIVIDER WITH REMOVABLE KNIVES

Description

2. Connect the roller to the drive means. This locking rod extends through an opening provided for this purpose in the lockable blades. Advantageously, the aforementioned support is part of the cutting blades and includes support blades having slots extending transversely to the longitudinal direction of the blades from a longitudinal edge 5 of these support blades. The intermediate blades also have transverse slots on the edge opposite to the edge containing the slots that interlock the locking blades. The support blades are arranged in the row such that the locking blades and the support blades extend substantially parallel to each other, and the slots in the support blades interlock the intermediate blades 10 at the location of the slots in the intermediate blades, while these latter slots interlock the support blades. Preferably, the support blades are supported by the locking rod.According to an advantageous embodiment, the blades have a cutting edge and a non-cutting edge along their longitudinal direction, the cutting edges of the blades extending along the same plane. According to a preferred embodiment of the divider, the lockable blades and / or support blades have fixing rings on the non-cutting side to accommodate the locking rod. According to an interesting embodiment, the blades have a substantially identical height transversely to their longitudinal direction, the fixing rings extending beyond this height. According to a very interesting embodiment, the slots provided in the blades have a width in the longitudinal direction of the blades that is greater than the thickness of the blades fitted into these slots. Generally, in the position furthest from the bottom and the grid, the grid is located below the bottom. According to an alternative form of realization, in the position far from the background and the grid, the grid is located above the background.30 Other details and features of the invention will become apparent from the following description, given by way of non-limiting example, of some particular embodiments of the invention, with reference to the accompanying drawings.

Figure 6 is a schematic view of a side section of a divider with the grid in a remote position below the bottom. Figure 7 is a schematic view of a lateral section of the divider of Figure 7 with the grid and background in a close-up position. In the different figures, the same reference numerals refer to the same or similar elements.The dough divider, according to the invention, is designed to cut a mass of dough into pieces by means of a grid comprising cutting blades. This machine, according to a first interesting embodiment of the invention, is schematically represented in Figures 1 to 7 and comprises a frame 20 with a tank 2 provided with a bottom 3 and a dividing device comprising a movable grid 7 which is displaceable in a substantially vertical direction. The upper side of the tank 2 has an access opening 4. The grid 7, shown in figures 2 to 4, has meshes 9 defined by intersecting cutting blades 10 to divide the dough mass 8 into 25 dough pieces 11. In the embodiment of the divider shown in the figures, the meshes 9 are rectangular, but can also be circular or have other shapes. The cutting blades 10 have a cutting edge 21 and a non-cutting edge 22 and include support blades 13, intermediate blades 14 and 30 locking blades 15.The cutting blades 10 have transverse slots 16 that are wider than the thickness of the cutting blades 10 and are designed to mount the intermediate blades 14 onto the support blades 13 and the locking blades 15 onto the intermediate blades 14. In this way, the cutting blades 10 are interlocked to form the grid 7. To this end, the transverse slots 16 comprise front slots 17 with an entry 19 at the cutting edge 21 of the cutting blade 10 and / or rear slots 18 with an entry 20 at the non-cutting edge 22 of the cutting blade 10. The front slots 17 and the rear slots 18 cooperate to connect the cutting blades 10 to each other. transversely, the cutting edges 21 being preferably placed in the same plane. 5 The support blades 13 have the front slots 17 to accommodate the intermediate blades 14 with their rear slots 18 provided to accommodate the support blades 13.The lockable blades 15 have rear slots 18 for enclosing the cutting blades 14 with their front slots 17 provided to accommodate the lockable blades 15.10 A locking rod 23 is provided to hold the cutting blades 10 in position when they are nested together to form the grid 7. Preferably, in a locked position, the rod 23 extends through the lockable blades 15 and beyond the non-cutting side 22 of the support blades 13, as shown in Figure 3. The lockable blades 15 have 15 rings 24 to accommodate the rod 23. The cross-section of the rings 24 is larger than the cross-section of the rod 23, particularly in the longitudinal direction of the lockable blades 15. Preferably, the cross-section of the rings 24 is such that it allows the rod 23 to be loosely positioned in the rings 24, preferably with a freedom of movement equal to half the thickness of the blades 1020 up to three times greater than the thickness of the blades 10.The cross-section of the rings 24 in the longitudinal direction of the locking blades 15 is, for example, equal to the cross-section of the rod 23 increased by half the thickness of the blades 10 up to five times the thickness of the blades 10. Consequently, a free space between the rings 24 and the rod 23 is provided. Because of this, the grid 7 is mounted somewhat 25 mobile and / or loosely connected with respect to the rod 23. The rod 23 preferably extends perpendicularly to the locking blades 15 and the support blades 13. Therefore, the locking rod 23 is preferably parallel to the intermediate blades 14. It is also possible for the rod 23 to extend through the lockable blades 30 15 and also through the support blades 13, not shown in the figures. As with the lockable blades 15, the rod 23 can also be loosely positioned through the support blades 13. BE2025 / 5046 5 Thus, it is not necessary to fix the blades 10 with screws. Furthermore, the grid 7 is easily removed by pulling out the rod 23, which can be done quickly and without tools.The grid 7 is mounted in a movable manner in the tank 2 and can be moved relative to the bottom 3, in a substantially vertical direction, through this bottom 3, by means of a drive device 12, as shown in Figures 6 and 7. To this end, the bottom 3 is composed of slots 6 separated by passage slots 5 to allow the cutting blades 10 of the grid 7 to pass through, as shown in Figures 5 and 6. The slots 6 thus fit into the meshes 9 of the grid 7. The bottom 3 and the grid 7 can extend substantially parallel to each other. The grid 7 is fixed to the drive device 12 by means of eyelets 24 through which the locking rod 23 extends, as shown in Figure 5. Figure 2. Therefore, the eyelets 25, or another means of attachment, allow the rod 23 to be fixed to the drive device 12. In a position far from the grid 7 relative to the bottom 3, a quantity 15 of a mass of dough 8 can be spread on the bottom 3 of the vat 2 and can rest on this bottom 3 without the cutting blades 10 passing through the mass of dough 8. In this position, the grid 7 with the cutting blades 10 extends below the bottom 3.In a position close to the grid 7 relative to the bottom 3, the cutting blades 10 pass through the dough mass 8 when it rests on the bottom 3 of the vat 2. When the grid 7 is moved through the bottom 3, the cutting blades 10 are pushed through the dough mass 8 to form the dough pieces 11. In this close position, the cutting blades 10 therefore first pass through the passage slots 5 of the bottom 3 of the vat 2 and then through the dough mass 8 when it rests on the bottom 3 of the vat 2, in particular, on the shims 6 of the bottom 3. The grid 7 can be fixed by the rod 23 to the drive device 12, as shown in Figure 3. Several rods 23 can be provided. Figure 3 shows two rods 23 which are mounted parallel to each other between the grid 7 and the drive device 12. The cutting blades 10 of the grid 7 are preferably interlocked and 30 mounted loosely so that the cutting blades 10 have a freedom of movement between them which is equal to half the thickness of the blades 10 up to three times the thickness of the cutting blades 10.Regarding the front slots 17, the rear slots 18 and / or the passage slots 5 have a width that is wider than the thickness of the BE2025 / 5046 6 cutting blades 10, preferably half to three times wider. In particular, a gap is to present the slots and the blades nested in this slot which is between half the thickness of the blades and three times the thickness of the blades. This loose composition brings about a reduction in friction between the grid 7 and the trowels 6 of the bottom 3 of the vat 2 when the cutting blades 10 of the grid 7 pass through the 5 passage slots 5. For cleaning the grid 7, it is easy to disassemble. The locking rod 23 is removed from the lockable blades 15 to disassemble the grid 7, preferably simply without tools, after which the lockable blades 15 are removed from the intermediate blades 14 and the intermediate blades 14 are removed from the support blades 10 13. Another embodiment of the divider according to the invention, not shown in the figures, differs from the previous one in that the grid 7 is mounted in its remote position above the bottom 3.In this second embodiment, the background 3 is not necessarily divided into pockets, but can form a continuous surface 15 without the passage slots. The grid 7, which constitutes a dividing device for dividing the mass of dough 8 into pieces 11, is mounted on the upper side of the vat 2, preferably in a removable manner that allows the grid 7 to be moved between an open and a closed position. In the open position, the vat 2 has an access opening 4.20 As in the first embodiment, the cutting blades 10 are nested one inside the other to form the grid 7. A locking rod 23 is provided to hold the cutting blades 10 in position when they are nested. The rod 23 can be mounted in a removable frame that allows the grid 7 to be moved between the open and closed positions.25 To cut a mass of dough 8 into pieces 11, the grid 7 is moved towards its open position, to make the vat2 accessible. A quantity of the mass of dough8 is then distributed on the bottom3 and the grid7 is moved towards the closed position.The training device 12 for moving the bottom 3 and the grid 730 relative to each other, in this embodiment allows the bottom 3 to be trained in the tank 2 in order to move it in a vertical direction. The bottom 3 of the vat 2 and the sieve 7, when the latter is in the closed position, can be moved between a distant position and a position BE2025 / 5046 7 close to each other. In the distant position, a space is present above the bottom 3, and below the sieve 7, allowing the dough mass 8 to be received. The blades 10 are pointed with their cutting edge towards the bottom 3. When the vat 2 and the sieve 7 are in the close position, the sieve 7 passes through the said space above the bottom 3 and cuts the dough mass 8 present there into dough pieces 11. In this 5th embodiment of the divider, the upper surface of the bottom 3 is adjacent to the lower side of the sieve 7 in the close position. Thus, to form the dough balls 11, the bottom 3 of the vat 2 is raised by the drive device 12 up to the grid 7 by passing the dough 8 through the meshes 9 of the grid 7.It would also be possible to move the grid 710 towards the bottom 3. Then, the grid 7 is moved to the open position to remove the dough pieces 11 from the bottom 3 of the vat 2. It is understood that the invention is not limited to the different embodiments described above, but that other variations can still be considered without departing from the scope of the present invention. For example, it is possible that in the second embodiment above, the bottom 3 is divided into slots 6 and has passage slots 5 for the cutting blades 10 of the grid 7. It is also possible, for example, that the number and / or position 20 of the locking rods, support blades, cutting blades and / or lockable blades is different from a number and / or position shown in the figure.
