Description
The invention relates to a conveying device for conveying wafers, comprising a conveying device forming a conveying section. In particular, the invention relates to a conveying device for wafers, for example in the frame of baking devices, for producing sweet wafers, in particular rolled ice cream wafer cartridges (rolled ice cream).
A conveying device for conveying baked goods, i.e. small bread, is known, for example, from DE 20 2006 003 637 U1, whereas a special conveying device for conveying wafers is known from EP 2 884 845 B1.
In some cases, the processing of wafers requires that the edge sections of the wafer are rolled up and pressed against the wafer by means of pressure rollers before further processing thereof. A conveying device of this type known from previous use operates in a circulating mode, in which the wafers are fed to folding devices integrated in the conveying device, which raise the edge sections of the wafers by means of a folding mechanism and fold them over the sections remaining in the plane of the wafers. In order to leave the turned-over edge section on the rest of the wafer, the edge section must also be pressed with pressure onto the section of the wafer that remains in this plane, after which the wafer thus processed can be transported further and, for example, subjected to processing into rolled ice cream wafers.
The disadvantage of this apparatus is that the circulating operation is not suitable for high production speeds and limits the overall productivity of the baking apparatus. Furthermore, pressing the edge sections with the aid of the pressure roller onto the wafer sections remaining in the plane of the wafer does not lead to satisfactory production results. In particular, the wafer thickness is reduced during pressing of the folded-over edge sections compared to the raw regions of the wafer.
The object of the invention is therefore to provide a conveying device for the production of wafers, in which the edge sections are to be turned over for further processing of the wafers, which conveying device enables high production speeds to be achieved with low expenditure on equipment.
This object is achieved according to the invention by a conveying installation having the features of claim 1. The dependent claims give further advantageous embodiments of the invention.
The basic concept of the invention is as follows: the structure of the equipment necessary for turning over the edge regions of the flat-formed (planar) wafers is integrated into the conveying section (conveyor section) so that the wafers can be handled during transport, without having to interrupt the conveying. On the basis of the invention, the production speed can be increased by using passively acting baffles (baffles), wherein the equipment expenditure and the maintenance expenditure associated therewith can be reduced at the same time.
According to the invention, a conveying apparatus for conveying wafers is proposed, having a conveying device forming a conveying section, wherein baffles (baffles) engaging into the conveying section are provided with an inlet section for receiving edge sections of wafers, a forced guide section and an outlet section; the forced guide lifts (raises) the edge section from the plane of the wafer and turns it over in the direction of the edge lying opposite it, above the wafer section remaining in this plane; the outlet portion places the edge sections of the folded wafer on the wafer sections (remaining in the plane) remaining in the plane.
The baffle engages into the conveying section in the following manner: the edge sections of the wafer are forced to perform a movement relative to the sections remaining in the plane of the wafer, which movement directs the edges of the edge sections above the wafer plane and in the direction of the edges lying opposite the edge sections in the plane. The folded edge sections rest against, in particular are pressed against, the sections of the wafer remaining in the plane. Since the use of flaps, in particular sharp-edged turning of the edge sections of the wafer (scharfkaniges Umschlagen) is possible, this sharp turning cannot be achieved by means of folding devices.
Preferably, the forced guide for performing, in particular, sharp-edged turning has a curve which extends transversely to the conveying path and turns (passes/bends/rolls) through 180 ° in the vertical direction.
Particularly preferably, the baffle has a support for supporting the folded edge sections of the wafers, which support extends from the opposite edges of the wafer sections remaining in the plane into the positive guide and is arranged above and spaced apart from the conveying section. This preferred design configuration forms channels in the baffle, which preferably correspond to the thickness of the wafer and cause the edge sections to fold in a precisely positioned manner.
According to a further preferred embodiment, the outlet section has a wall arranged above the conveying section, the distance of which from the conveying section is less than twice the layer thickness of the wafers to be transported. Due to this design construction it is ensured that: the folded edge sections are pressed in a defined manner to the sections remaining in the plane of the wafer without the pressure being actively applied to the folded edge sections by means of pressure rollers.
The conveying device of the conveying installation is preferably formed as a belt conveyor. The strip or strips preferably run here in a table serving as a support surface for the wafers to be transported. In particular, at least two conveyor belts are provided which are arranged on top of one another and are driven in opposite directions, at least in certain regions, at a distance from one another which is less than the layer thickness of the wafers to be transported. The wafer is sandwiched between these belts and gently (gently/protectively) transported by means of the belts.
In particular, the conveying device has rollers which guide the conveyor belt of the belt conveyor at a horizontal distance from one another which is smaller than the diameter of the wafers to be transported. This design makes it possible to apply the transport forces to the individual wafers uniformly.
In particular, at least two first rollers arranged transversely to the conveying direction and at least two second rollers arranged transversely to the conveying direction are provided for this purpose, which are arranged one behind the other, as viewed in the conveying direction, wherein the first and second rollers are arranged on an imaginary plane which is smaller than the surface (area) of the wafer to be transported. This ensures that the four rollers are always in contact with the wafers to be transported.
Most preferably, the rollers of the lower conveyor belt and the rollers of the upper conveyor belt are arranged alternately, as seen in the conveying direction.
Finally, a waffle baking apparatus with the above-described conveying apparatus is proposed.
In particular, a conveying device constructed according to the invention is provided for round-structured wafers which are to be further processed to rolled ice cream cones (Eist cream). In principle, however, the conveying apparatus is also suitable for other forms (shapes) of wafers which require turning over of edge sections onto wafer sections which remain in the wafer plane.
The invention will be further elucidated on the basis of an embodiment which is shown in the drawing, in particular in a preferred design configuration. The figures show:
fig. 1 shows a schematic top view of an embodiment of a particularly preferred configuration of the conveying installation according to the invention;
fig. 2 shows a perspective view of the conveying device shown in fig. 1 from above;
fig. 3 shows a perspective view of the transport device shown in fig. 1 from below; and
fig. 4 shows a baffle according to a particularly preferred embodiment of the invention in a front view (a) from the inlet side, in a side view (b) from the side of the conveying section of the conveying device, in a rear view (c) from the outlet side, in a plan view (d), in a perspective view (e) from the outlet side and in a perspective view (f) from the inlet side.
Fig. 1 shows a schematic top view of a particularly preferably constructed embodiment of the conveying device according to the invention. In particular, fig. 1 shows a conveying device 10 for conveying wafers 30, which has a conveying device 20 forming a conveying section. In the illustrated embodiment, the conveying device 20 is formed as a belt conveyor having a plurality of conveyor belts 22, which conveyor belts 22 are arranged parallel to one another and one above the other (overlapping arrangement), above and inside the table portion 26 on which the wafers 30 are placed. The conveyor belt 22 is guided on rollers 24 arranged above, below and inside the table.
In the example shown, the conveying section formed by the conveyor belt 22, the rollers 24 and the table 26 is provided with a flap 40, into which the flap 40 engages (fits), having an inlet portion 42 for receiving an edge section 32 (imaginary indicated by a dashed line) of the wafer 30 shown on the right and an outlet portion 46 for outputting the processed wafer 30'. Between the inlet portion 42 and the outlet portion 46, a forced guide 44 is provided, which forced guide 44 lifts (raises) the edge section 32 out of the plane of the wafer 30 and inverts it over the wafer section 34 remaining in this plane in the direction of the edge lying opposite it, so that the wafer 30 is received unprocessed (untreated/naturally) by the inlet portion 42 and the inverted edge section 32 of the wafer 30 leaves the outlet portion 46 in a manner lying on the wafer section 34 remaining in this plane.
As can be clearly seen in fig. 1, the raw wafer 30 has an overall rounded (surface) surface at the beginning of the conveying section before passing the baffle 40, wherein the (surface) surface of the wafer 30' after passing takes the form of a circle which appears to be reduced by one sector (segment). In fact, the treated wafer 30' appears cut in top view, because the edge sections 32 of the wafer 30 are turned over by the baffle 40 and rest on the wafer sections 34 that remain in plane.
Fig. 2 shows a perspective view of the conveying device shown in fig. 1 from above, wherein it can be seen that the belt conveyors 20 each have two conveyor belts 22, which conveyor belts 22 are arranged one above the other (arranged one above the other) and are driven in opposite directions at a distance from one another which is smaller than the layer thickness of the wafers 30, 30' to be transported. By this construction, the wafer 30, 30' can be transported gently (protected). The conveyor belts 22 are driven by a common drive 28.
In particular, it is provided that the rollers 24 of the conveyor belt 22 of the guide belt conveyor 20 are at a horizontal distance from one another which is smaller than the diameter of the wafers 30, 30' to be transported. In particular, two first rollers 24 are provided, which are arranged transversely to the conveying direction and two second rollers 24 are provided, which are arranged behind one another, as viewed in the conveying direction, wherein the first and second rollers 24 are arranged on an imaginary plane which is smaller than the surface (volume) of the wafer 30, 30' to be transported. By means of this design configuration, the wafer 30, 30' can be transported particularly gently.
Fig. 3 shows a perspective view of the conveyor device 10 from below, wherein it can be seen that rollers 24, which guide the conveyor belt 22 on the upper side of the table 26, pass through in contact with (act on) the table.
Finally, fig. 4 shows a baffle plate according to a particularly preferred design of the invention in a front view (a) from the inlet side, in a side view (b) from the side of the conveying section of the conveying device, in a rear view (c) from the outlet side, in a plan view (d), in a perspective view (e) from the outlet side and in a perspective view (f) from the inlet side.
The baffle 40 has an inlet portion 42, a forced guide portion 44 and an outlet portion 46, the inlet portion 42 being for receiving the edge section 32 of the wafer 30; the forced guide 44 lifts (lifts/raises) the edge section 32 out of the plane of the wafer 30 and inverts it over the wafer section 34 remaining in this plane in the direction of the edge lying opposite it; the outlet section 46 places the edge sections 32 of the inverted wafer 30 on the wafer sections 34 remaining in that plane (the remaining wafer sections 34 in that plane). In particular, the forced guide 44 arranged between the inlet 42 and the outlet 46 is designed as a curve which engages laterally (from the side) into the conveying section and winds (coils/bends/turns) through 180 ° in the vertical direction.
In order that the edge sections 32 do not come into premature contact with the flat wafer sections 34 when the edge sections 32 are turned over, the baffle 40 has a support 48 for supporting the turned-over edge sections 32 of the wafers 30, the support 48 extending from the opposite edge of the flat wafer sections into the positive guide 44, arranged above and spaced apart from the conveying section.
The outlet section 46 of the baffle 40 is finally formed by a wall arranged above the conveying section, which wall is at a distance from the table 26 of the conveying section that is less than twice the layer thickness of the wafers 30 to be transported. With this design, the individual regions of the wafer 30 conveyed by the conveying device 20 are guided together under slight pressure, so that the turned-over edge sections 32 continuously rest against the wafer sections 34 remaining in the plane of the wafer 30.
