Description
Technical Field
The invention relates to a conveying device for conveying wafers, comprising a conveying means forming a conveying path. In particular, the invention relates to a conveying device for wafers, for example in the frame of a baking device, for producing sweet wafers, in particular rolled ice cream Hua Futong (rolled ice cream).
Background
A conveyor device for conveying baked goods, i.e. rolls, is known from DE 20 2006 003 637 U1, for example, wherein a special conveyor device for conveying wafers is known from EP 2 884 845 B1.
In some cases, the processing of wafers requires rolling up the edge sections of the wafers and pressing them against the wafers by means of pressure rollers before further processing thereof. A conveyor device of the type known from previous use operates in a circulating operation, in which wafers are fed to a folding device integrated in the conveyor device, which lifts an edge section of the wafer by means of a folding mechanism and folds it onto a section remaining in the plane of the wafer. In order to leave the turned-over edge section on the rest of the wafer, it must also be pressed with pressure onto the section of the wafer left in this plane, after which the wafer thus processed can be transported further and, for example, subjected to processing into a rolled-up ice cream wafer.
The disadvantage of such an apparatus is that the cyclic operation is not suitable for high production speeds and limits the overall productivity of the toasting apparatus. Furthermore, pressing the edge sections onto the wafer sections remaining in the plane of the wafer by means of pressure rollers 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 unprocessed areas of the wafer.
Disclosure of Invention
The object of the present invention is therefore to provide a conveying device for the production of wafers, in which the edge sections should be turned over for further processing of the wafers, which conveying device enables high production speeds with low equipment outlay.
This object is achieved according to the invention by a conveying device having the following features: a conveying apparatus for conveying wafers, having a conveying device forming a conveying section, a baffle plate engaging into the conveying section, the baffle plate being provided with an inlet portion for receiving an edge section of the wafers, a forced guiding portion and an outlet portion; the forced guide lifts the edge section from the plane of the wafer and turns the edge section over the wafer section remaining in the plane in the direction of the edge lying opposite it; the outlet portion places the edge section of the inverted wafer on the wafer section remaining in the plane, wherein the baffle has a support portion for supporting the inverted edge section of the wafer, which extends from the opposite edge of the wafer section remaining in the plane into the forced guide portion, is arranged above and spaced apart from the transport section, and wherein the outlet portion has a wall arranged above the transport section, which wall is at a distance from the table portion of the transport section of less than twice the layer thickness of the wafer to be transported.
The basic idea of the invention is: the structure of the equipment necessary for turning over the edge regions of the flat (planar) wafers is integrated into the transport section (conveyor section) so that the wafers can be handled during transport without interrupting the transport. The invention can be used to increase the production speed by using a movable baffle (partition), wherein the equipment costs and the maintenance costs associated therewith can be reduced at the same time.
According to the invention, a conveying device for conveying wafers is proposed, which has a conveying means forming a conveying section, wherein a baffle (partition) joined into the conveying section is provided with an inlet portion for receiving an edge section of a wafer, a forced guiding portion and an outlet portion; the forced guiding portion lifts (lifts) the edge portion Duan Conghua wafer in the plane and turns the edge portion left in the plane over it in the direction of the opposite edge; the outlet portion places the edge section of the folded wafer on the wafer section remaining in the plane.
The baffles are engaged into the conveying path in the following manner: the edge section of the wafer is forced to perform a movement relative to the section remaining in the plane of the wafer, which guides the edge of the edge section above the Xiang Huafu wafer plane and in the edge direction opposite the edge section in the plane. The folded edge section rests on, in particular is pressed against, a section of the wafer which remains in the plane. Thanks to the use of the baffle, in particular sharp edge turning (scharfkantiges Umschlagen) of the edge section of the wafer is possible, which sharp turning cannot be achieved by means of the folding device.
Preferably, the forced guide for performing in particular sharp-edged turning has a bend which extends transversely to the conveying path and is turned (by-passed/bent/rolled) 180 ° in the vertical direction.
Particularly preferably, the baffle has a support for supporting the folded edge sections of the wafer, which extends from the opposite edges of the wafer sections remaining in the plane into the forced guide and is arranged above the transport section and spaced apart therefrom. This preferred design configuration forms channels in the baffle, which preferably correspond to the thickness of the wafer and result in the edge sections being folded in a precisely positioned manner.
According to a further preferred embodiment, the outlet section has a wall arranged above the transport section, the distance of which from the transport section is less than twice the layer thickness of the wafer to be transported. Due to this design configuration, it is ensured that: the folded edge sections are pressed in a defined manner to the sections remaining in the wafer plane without having to actively apply pressure to the folded edge sections by means of pressure rollers.
The conveying means of the conveying device are preferably formed as a belt conveyor. The one or more strips preferably extend here in a table which serves 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 each other and are driven in opposite directions, at least in certain areas, at a distance from each other which is smaller than the layer thickness of the wafer to be transported. Wafers are sandwiched between these belts and transported gently (gently/protectively) by the belts.
In particular, the conveying device has rollers that guide the conveyor belt of the belt conveyor, which are horizontally spaced from one another by a distance that is less than the diameter of the wafers to be transported. By this construction, the force acting as a transport can be applied uniformly to the individual wafers.
In particular, for this purpose 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, which are arranged one after the other, seen in the conveying direction, wherein the first rollers and the second rollers are arranged on an imaginary plane smaller than the surface (area) of the wafer to be conveyed. This ensures that the four rollers are always in contact with the wafer to be transported.
It is most preferably provided that the rollers of the lower conveyor belt and the rollers of the upper conveyor belt are arranged alternately, seen in the conveying direction.
Finally, a wafer baking apparatus having the above-described conveying apparatus is proposed.
In particular, the conveying device constructed according to the invention is provided for wafers of circular construction which are to be further processed into rolled ice cream cones (ice cream rolls). In principle, however, the conveying device is also applicable to other forms (shapes) of wafer which require the edge sections to be turned over onto the wafer sections remaining in the wafer plane.

Detailed Description
Fig. 1 shows a schematic top view of an embodiment of a particularly preferred construction of a conveying device according to the invention. In particular, fig. 1 shows a conveying device 10 for conveying wafers 30, which has a conveying means 20 forming a conveying path. In the embodiment shown, the conveyor means 20 are formed as a belt conveyor with a plurality of conveyor belts 22, which are parallel to each other and are arranged one above the other (overlapping arrangement), which are arranged above and inside the table portion 26 where the wafers 30 are placed. Here, the conveyor belt 22 is guided on rollers 24 arranged above, below and inside the table.
In the example shown, the conveying path formed by the conveyor belt 22, the rollers 24 and the table 26 is provided with a baffle 40, into which the baffle 40 engages (fits), with an inlet portion 42 for receiving an edge section 32 (indicated by the dashed line) of the wafer 30 shown on the right side and an outlet portion 46 for outputting the processed wafer 30'. Between the inlet 42 and the outlet 46, a forced guide 44 is provided, the forced guide 44 lifting (raising) the edge section 32 from the plane of the wafer 30 and turning 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 42 and the turned-over edge section 32 of the wafer 30 leaves the outlet 46 in such a way that it rests on the wafer section 34 remaining in this plane.
As can be clearly seen in fig. 1, the unprocessed wafer 30 has an overall circular (surface) surface at the beginning of the transport path before passing through the baffle 40, wherein the (surface) surface of the wafer 30' assumes a circular form that appears to be reduced by one sector (arcuate segment) after passing through. In fact, the processed wafer 30' appears to be cut in top view, as the edge section 32 of the wafer 30 is turned over by the baffle 40 and placed on the wafer section 34 left in the plane.
Fig. 2 shows a perspective view of the conveying apparatus shown in fig. 1 from above, wherein it can be seen that the belt conveyor 20 has two conveyor belts 22 per (channel) which are arranged one above the other (one above the other) and are driven in opposite directions, at a distance from each other which is smaller than the layer thickness of the wafers 30, 30' to be transported. By this configuration, the wafers 30, 30' can be transported gently (protected). The conveyor belt 22 is driven here by a common drive 28.
In particular, it is provided that the horizontal distance of the rollers 24 of the conveyor belt 22 guiding the belt conveyor 20 relative to each other is smaller than the diameter of the wafers 30, 30' to be transported. In particular, two first rollers 24 and two second rollers 24 are provided, which are arranged transversely to the conveying direction and are arranged one after the other, as seen in the conveying direction, wherein the first and second rollers 24 are arranged on an imaginary plane which is smaller than the surface (area) of the wafer 30, 30' to be conveyed. By this design configuration, the wafers 30, 30' can be transported particularly gently.
Fig. 3 shows a perspective view of the conveyor apparatus 10 from below, wherein it can be seen that the conveyor belt 22 is guided on the upper side of the table portion 26 through rollers 24 which are in contact with (act on) the table portion.
Finally, fig. 4 shows the baffle according to the invention in a front view (a) from the inlet side, a side view (b) from the conveying section side of the conveying device, a rear view (c) from the outlet side, a top view (d), a perspective view (e) from the outlet side and a perspective view (f) from the inlet side.
The baffle 40 has an inlet portion 42, a forced guiding portion 44 and an outlet portion 46, the inlet portion 42 for receiving the edge section 32 of the wafer 30; the forced guide 44 lifts (lifts/lifts) the edge section 32 from the plane of the wafer 30 and turns it over the wafer section 34 remaining in that plane in the direction of the edge lying opposite it; the outlet portion 46 places the edge section 32 of the inverted wafer 30 on the wafer section 34 remaining in that plane (the wafer section 34 remaining 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 (sideways) into the conveying section and rolls up (winds/bends/turns) 180 ° in the vertical direction.
In order that the edge section 32 does not prematurely contact the wafer section 34 remaining in the plane when the edge section 32 is turned over, the baffle 40 has a support 48 for supporting the turned-over edge section 32 of the wafer 30, the support 48 extending from the opposite edge of the wafer section remaining in the plane into the forced guide 44, being arranged above the conveying section and spaced apart therefrom.
The outlet portion 46 of the baffle 40 is finally formed by a wall arranged above the transport section, which wall is at a distance from the table portion 26 of the transport section of less than twice the layer thickness of the wafer 30 to be transported. By this design, the partial areas of the wafer 30 conveyed by the conveying device 20 are guided together under slight pressure, so that the inverted edge section 32 continuously rests on the wafer section 34 remaining in the plane of the wafer 30.
