Suomi-Finland (FI) (7 * 0 Tampereen Patenttitoimisto (5 * 0 Machine for making bun lengths - Maskin för tillverkning av en vetetrödslängd

The invention relates to a machine of the type defined in the preamble of claim 1 for producing bale lengths.

The manufacture of braided bun lengths in bakeries is very common as they are quite popular among consumers. The manufacture of such lengths has hitherto been carried out almost entirely by hand, since it has not yet been possible to develop a suitable, usable machine. However, machines have already been proposed and built in the past for making braided bundles from three or more dough bars. In these machines, the dough bars are formed in an extruder whose nozzles are arranged to perform such a movement with each other as to result in a braid-like = 57686 braid which is lowered from the nozzles onto a conveyor advancing below and then cut into suitable pieces for further processing. The mechanism of such a machine is described, for example, in German application DOS 2 161 039.

Finnish patent application 2987/66 discloses a method for machine-making a bobbin length, in which case a machine operating by this method forms a jacket tape, in which a loop is first made, after which the machine loops the bundle length tape in each case. However, a major disadvantage of this method is that the dough bar is subjected to high mechanical stresses during manufacture.

GB patent 864 185 discloses a device for producing a threaded length. The bakery product according to the publication is made by twisting two pieces of dough bar around each other several times in the longitudinal direction of the bar.

However, a common disadvantage of these known devices is that the braiding mechanism is quite complex and sensitive to interference. Also, the dough does not always come out of all the nozzles as a flat rod, but tears and may break the jacket. Long braiding is not always possible directly from the dough bars coming from the nozzles. It would be advantageous for the quality of the product if the dough bars could be further modified between extrusion and braiding. However, this is not possible with current machines.

The object of the present invention is to provide a new machine for the above-mentioned purpose, which does not have the grievances.

The machine according to the invention has a rolling device producing two or more dough bars and means for conveying and placing the dough bars on a conveyor belt in a braid-like length, the machine according to the invention being characterized by comprising at least two whose outlet pipe is slightly bent to the side with respect to the axis and through which the dough bars are guided from the rolling device by means of strip conveyors.

According to another feature of the invention, at least some of the belt conveyors are adapted to perform, in addition to the longitudinal conveying movement, a reciprocating transverse movement to perform transverse rolling of the dough bars between the overlapping belt conveyors to shape and dimension them.

According to a further feature of the invention, the dough guide funnel or the like is adapted to guide the dough bars into an interlocking thread on a belt conveyor below the guide funnels to form a length. the speed is slightly lower than the previous one. __ __ _ ____

According to a further feature of the invention, the speed of all belt conveyors can be infinitely adjusted, e.g. by means of variators.

By means of the invention, a machine with a simpler structure and a safer and more efficient operation is obtained than previously known.

An embodiment of the invention is illustrated in more detail in the following description with reference to the accompanying drawings, in which Figure 1 schematically shows a machine according to the invention in a side view, Figure 2 shows the same machine in top view, Figure 57686 schematically shows a dough bar rotating and setting device and front conveyor in front view in a partial view, Fig. 4 shows the rotating control funnels of the dough bar setting device enlarged compared to the previous one, seen from the front, Fig. 5 shows the same when viewed from above. _

The machine according to the invention (Figures 1 and 2) has, for example, an elongate frame 1 made of steel structures, on which it is mounted on the floor of the work space. From the tank 2 mounted on the right end of the machine, the dough travels in the direction of travel of the rollers 3 in the lower part of the tank due to the friction formed by their movement and the suction of the dough thread already in the grooves of the rolls. The long thread blanks provided by the rollers are transferred via guide rollers to a conveyor 4 which moves in the longitudinal direction of the machine. With the conveyor 4, the dough strands are transferred to a transverse rolling conveyor, which is located at a suitable distance from the tank 2 in the direction of travel of the conveyors 4 above it. The transverse rolling conveyor 5 is e.g. 20 mm above the conveyor 4, its direction of travel for the dough strand being the same as the direction of movement of the conveyor 4. Em. the transverse rolling conveyor 5 further performs a reciprocating reciprocating movement with respect to its direction of travel, while allowing the continuous continuous movement of the long strands, giving the strand a rod-like shape. This improves the quality of the dough strands and makes it easier to make the dough.

The speed of the conveyor 6 after cross-rolling is higher because the long blank becomes thinner during cross-rolling. The finished long strands are guided by guide wheels to a long forming device 7, where they pass through rotating guide hoppers 8. The funnels are connected to each other by means of equal gears 9, (Figs. 3, 4, 5), whereby they rotate in different directions. The guide hole of the hoppers is relatively wide relative to the dough bar, so that the dough bar is easily guided through the hopper. The inlet nozzle 10 below the hopper is turned slightly obliquely to the side, whereby as the device rotates and the receiving conveyor 11 below advances, the dough bars land on the conveyor, each forming a continuous thread. When the side-turned inlet nozzles are turned to the side with a phase difference of about 90 °, the threads of dough bars formed by the nozzles intersect and overlap each other, forming a bun-length considerably resembling a braided length. The conveyor of the finished long blank is in two parts, of which the speed of the conveyor after the conveyor 11 (not shown in the figures) is lower than that of the conveyor 11, whereby the advantage that the long is compacted is achieved. At a suitable point above the above-mentioned conveyor there is a cutter which cuts the long blank to a certain length.

The various functions of the machine are adjusted by means of variators, whereby the speeds of the conveyors are made to correspond to the speed of the long blank required in each case.

With the machine according to the invention, more than two dough bars can also be used, such as, for example, three, in which case a 3-thread length is obtained.

The device according to the invention may vary slightly within the scope of the claims.
