Description

[Detailed description of the invention] For example, a flat pad for Swiss rolls. Method and device for rolling up dough pieces The invention is a piece of baked and rolled out dough for bread dough analogy swiss rolls. Regarding how to involve.

These operations are primarily carried out in large, specialized, bread-making factories with industrial production. Even then, it was done by hand. All this work, for example, the use of a rolling cloth Attempts were made to mechanize it, but this proved to be extremely difficult. Proven. The choice is partly due to problems, but also because the action of the machine is often Because it is easy to cause roll-in, it is important to avoid this occurring at the beginning of roll-up of the dough material, and The department has determined that the known proposals for reasonably effective machines meet certain requirements with respect to operational reliability. It's because I left hope behind.

However, the already proposed methods are easy and partially effective for mechanical implementation. the front edge of the flat dough material in a suitably inclined position. is brought into contact with a conveyor belt passing upwards over the dough material, thereby The conveyor belt frictionally engages the edges of the dough material and performs the initial roll-up of the dough material. between the engulfed material part and the conveyor. The inclination is mainly carried out by the continuous engagement of the dough material. This corresponds to an increase in the diameter of the portion that is rolled up as it progresses backwards towards the contralateral end.

However, this method is not completely effective, and to increase work safety, It was recommended that the front edge of the dough material be raised to ensure the first contact. . However, such an increase requires increased mechanical complexity and cycle time. Essential. In another attempt, the conveyor belt was fitted with protrusions, but the problem still persisted. Not resolved.

The present invention provides a simple and convenient method by using multiple parallel strings to the conveyor belt. An effective solution is obtained, in which the string has an elastic and protruding carrier member. and is guided around a roller adjacent to the leading edge of the dough material, said roller A protrusion or lip located between the strings that protrudes more than the carrier member. has a The front edge of the dough material is directly acted upon by these protrusions or ribs. The first winding was caused by a strong impact from a distant protrusion on the thin roller. Achieved with more help, so that the protrusions apart when the dough material is rolled up In order to be acted upon by the string carrier without being acted upon by It has been found that a very high degree of safety in the subsequent engulfment is achieved.

The invention, including apparatus for carrying out the method, will be described with reference to the drawings, in which in, FIG. 1 is a diagrammatic perspective view of a device known in principle for winding Swiss rolls; FIG. 2 is a perspective view of the end of a conveyor designed in accordance with the present invention; Figures 3 to 6 are a series of side views showing the mode of operation of the device; Figures 7 and 8 are side views showing the manufacture of conveyor strings; FIG. 9 is a diagrammatic side view showing a modified conveyor.

The device shown in FIG. It is installed protruding across the The device has a chassis 6 which is fixedly guided. A cylinder 10 is attached to the support 8 so that it can reciprocate along the conveyor belt 2. It is attached to the sea urchin.

Above the belt 2 and on the opposite outside, the chassis 6 is provided with an associated motor 14. It supports the belt roller 12. A hinged frame 16 is attached to the shaft end of this roller. Attached to the frame 16 is a strip at its free end further supported by a crosspiece 20. A crosspiece 20 supports a shaft or roller 18 and is connected to the chassis 6 via a cylinder 22. The cylinder 22 determines the height position of the narrow roller 18.

A belt 24 is placed around rollers 12 and 18, and the belt 24 is fully It also passes through the circumference Q of the flexible and thin roller 18 and has a rough surface. roller 1 2 is installed upwardly above the conveyor 2, and the downward running path of the belt 24 is a thin roller. It passes diagonally upward from the conveyor belt 2, and when it comes down, it is located just above the conveyor belt 2. descend.

The upper part of the chassis 6 is pivoted to a part supported by a guide support 8, where it It can be swung up and down by a pair of cylinders 26, thereby allowing the row 21 The height position of 2 can be adjusted as desired.

In the starting position, the chassis 6 is placed at the rightmost position of the guide support 8. and the narrow roller 18 is lifted somewhat above the conveyor belt 2. bread raw The base materials 4 are placed on this belt with their outer ends marked 5 just below the narrow row 218. placed so as to be moved towards the front and inner areas. In this regard Chassis 6 is illustrated in which the length of the horizontal section of the chassis is changed to facilitate adjustment of the flow. It is possible to install devices that do not cover the entire belt 24 across the conveyor 2. can be displaced in the direction.

When the dough material 4 is moved to a position below the belt 24, the cylinder 22 is actuated. The thin roller 18f is lowered, and the cylinder 10 is activated to control the entire chassis 6. It moves to the left at the same speed as conveyor 2. By lowering the roller 18, the base The route 24 now captures the edge of the dough material and the object is indicated at 28. The rolled material then rolls over the end of the conveyor belt 2 and rolls onto other parts. A suitable receiving device such as a conveyor belt 30 is reached.

There, the thin roller is lifted up and the entire chassis 6 quickly moves to the right and is connected to the device. The bread dough material 4 is received and prepared for processing.

The device described above is such that the roller 18 is a smooth roller co-acting with a suitable friction belt 24. It operates according to the above-mentioned principle.

However, according to the invention, the roller 18 (see FIG. 2) is provided with a protrusion or rib 32. The conveyor belt is made up of a number of parallel strings 34. and they fit into the grooves 36 of the large roller 12 and the recesses of the ribs 32 of the small roller 18. It is received in a similar groove formed by the location 30. Are the strings elastic plastic? and is held between rollers 12 and 18 with a slight elastic extension.

The string is fitted with a carrier, it can be a simple knot on the string, but is preferred Alternatively, such as the protruding flange of a tubular rivet 42 permanently secured to the string. , a significantly protruding carrier is used.

The drive roller 12 captures the carrier 40 permanently or occasionally to ensure drive engagement with the string. It can be provided with a number of longitudinal grooves that fit together. When the strings are elastic, they are reasonably tensioned despite the change in length that occurs as the carrier passes around the rollers. It remains as it is.

Figures 5 and 6 show how the dough material is initially rolled up. bread raw The background material is placed with its front end 5 just below the roller 18 and when the roller descends the front end 4 is pushed upwardly and forwardly by corresponding ribs 32 on roller 18. As shown in Figure 2, when the string is transported backwards to a certain extent, the roundness of that part is corrected and the elastically presses against the raised front edge of the fabric material.

During this operation, sooner or later the carrier 40 is exposed to the dough material being captured by the string. (see figure 6), so that the engulfed part is particularly pressed, and it is I support the first involvement. This causes some noticeable tears in the dough material; This is not a big deal since the front part is hidden by the finished product. similar During the subsequent rolling process, the surface of the dough material is regularly driven from the carrier. However, as the diameter of the roll increases, the corresponding scraping effect gradually decreases. A little, from the last hundred finished products virtually completely gone.

In a preferred embodiment, the tubular rivets 42 are 2-3 crrL apart from each other on the string 34. The flange 38 protrudes from the surface of the string by 1/2 to 1 inch, thereby However, an effective carrier effect is produced on the engulfed object. Roller rib 32 and The carrier effect of the rivet flange and rivet flange is suitable for carrying out the first winding at low speeds. , so that the motor 14 slows down as the frame 16 pivots downward; Accelerates immediately when engagement between the grooved roller 18 and the entrained object begins. should be controlled as follows.

The rivets 42 can be attached to the string by tying a knot behind them or by deforming them into the string. It can be fixed by fixing. However, preferably FIG. The installation method shown in is used. A string 34 of elastic thermoplastic material is used. , its ends are heated and stretched to a very narrow diameter as shown at 46.

At the end 46 a number of tubular rivets 42 are pushed in, after which the string is pushed out of the section 46. It is extended between the end and the squeeze tool 48. The diameter of the string is thereby reduced enough to The dot 42 can be easily pushed to the desired position on the string. string extension is stopped When the string is fully expanded, the rivet is shown to the right of the squeeze tool 48. As shown, it is firmly fixed only by the compression effect of the strings. Moderate string elongation i.e. when the rivet is properly sized, it remains completely fixed during the operation. Be unified.

In Section 8, another method of forming a carrier on the (-1 string 34 is shown. As shown, a thermoplastic string is formed into a thickened section 50 by a butt welding tool 52. shows how it is done. However, the present invention is limited to specific designs of carriers. Emphasize that this is not fixed. In chiru applications, the string or corresponding bell It is sufficient that the seat has a discontinuous carrier-free friction surface.

Other applications, on the contrary, require a reliable carrier for the initial entrainment, while these is unnecessarily hard to wrap the object 2 during the final wrap. Figure 9 shows such a case, It is shown that the switching is achieved by using intermediate roller 54, From 54 a string 56 with a carrier of the first type extends to a narrow roller 18 and carries a carrier of another type. A string 58 with a carrier of the same size or size extends to the drive roller 12. . The intermediate roller 54 can be a driven roller, or else this roller can be freely suspended by strings 56 or 58.

In the embodiment shown in Fig. 2, it is possible to connect the strings with transverse screws to create a network structure. exists, and the transverse screw optionally constitutes a carrier, but such an arrangement is of course This can be used for the embodiment shown in FIG.

The protrusions or ribs 32 on the front roller 18 further extend the rows on the string or belt 34. It is important that the carrier roller, which reaches the circumference 9 of the roller, also protrudes significantly from the roller. Kaname dechiru. The cross-sectional shape of the protrusion or rib 32 is not particularly strict; Preferably their shape is round as shown. Reasonable spacing between protrusions or ribs should be present, and the roller 18 should also have a local pick-up on the front part that involves the object. Usually there are 4 to 8 protrusions because the diameter should be small to produce sound effects. installed on rollers. The thickness of the fabric material is usually 1/2 to 1crrL. Therefore, the rib 32 protrudes from the surface of the roller by 11/2 to 2 cm. Appropriate.
