Description

The invention relates to a cutting station, a system for producing end products by cutting flat wafers blocks and a method for cutting waffle blocks and in particular for separating the lateral, parallel to the cutting direction edge of the waffle blocks.

Waffle blocks are intermediates for the production of baked products, which preferably have multi-layered waffle layers lying one above the other. These waffle layers are crispy, brittle and / or thin-walled wafer layers, which are baked in a baking machine with circumferentially arranged, lockable baking tongs under increased pressure. Subsequently, the individual wafer sheets are coated with a mass such as a cream or filled and laid in layers over each other. The wafer blocks thus produced have, for example, a size of about 40 × 80 cm, in particular of 35 × 73 cm, and a thickness of about 7 mm to 3 cm. The products to be produced therefrom are known, inter alia, as waffle slices and usually have the shape of a bite-sized cuboid. To make these products, the edge of the waffle blocks must be cut or cut so that the outer edges of the waffle block have a desired smooth shape. The waffle blocks produced as an intermediate product have no homogeneous edge area, since on the one hand the wafer sheets can not be evenly coated to the edge with the cream and on the other hand, the edge of the wafer sheets during the baking process can not be given an exactly predictable shape.

Furthermore, the relatively large waffle blocks must be cut to form cuboid bite or edible end products. Optionally, the wafer blocks are cut by inclined cutting body in prismatic end products, for example, have a trapezoidal profile. Preferably, the wafer blocks are divided by two substantially orthogonal sections, so that end products arise with substantially rectangular bases.

The cutting of the waffle blocks is done according to the prior art in that a waffle block is pushed through a cutting frame. In the cutting frame cutting wires or cutting bands are stretched. By pushing through the waffle block is cut by the cutting wires or cutting bands. After being pushed through the first cutting frame, the block is pushed through a second cutting frame, wherein the first cutting direction and the second cutting direction are 90 ° to each other. Through this second cut, the desired end products are formed.

A disadvantage of the devices of the prior art is that when cutting the waffle blocks often comes to break out of wafer parts in the edge region and in particular in the rear corner regions. This increases rejects and thus reduces the efficiency of the entire process for producing the final products.

The breaking of the corners can be prevented in the prior art, that a relatively wide edge is cut off. However, this also reduces the efficiency of the process, as the wide cut edge is also eliminated as scrap.

Thus, according to the prior art, there is a conflict of objectives in the improvement of the efficiency, which is in particular a conflict of objectives between the separation of the narrowest possible edge and the break-free separation of the edge.

The object of the invention is now to solve this conflict of goals.

It has been found, in a manner which is surprising to a person skilled in the art, that the breaking off of the corners can be prevented or at least reduced if the waffle block is pushed or pushed when pushed through the cutting area on the rear end side of the edge of the waffle block. The rear face of the waffle block is that side of the waffle block that is rearward in the cutting direction, that side on which a sliding body engages to push the waffle block into or through the cutting area.

The rear end face of the edge of the waffle block is that area of the waffle block which lies on the rear end face of the waffle block, in the region of the edge which is to be separated by the cutting body or bodies. Thus, the device according to the invention during the cutting process supports the wafer block in the region of the rear end side of the edge to be cut off.

In order to keep according to the invention the edge to be cut as narrow as possible, the cutting body, in particular the outer cutting body for separating the edge, arranged as far outside as possible.

Since the sliding body must push the waffle block through the cutting area, must be provided in the sliding body for each cutting body an exemption, so that the Slide body does not collide with the one or more cutting bodies when pushing the wafer block through the cutting area. In the narrow edge region, however, this means that the distance between the side edge of the sliding body and the first release for the cutting body for the separation of the edge corresponds at most to the width of the edge. This edge width is for example 3 mm. After deducting the tolerance of the playful leadership of the sliding body remains as a lateral portion of the sliding body only a thin web left over, which is not suitable to effect sufficient support of the rear end side of the edge.

The object of the invention is therefore achieved, in particular, in that the sliding device comprises a first sliding body and a second sliding body, that the first sliding body and the second sliding body via a drive, optionally via a plurality of drives, along or in the direction of the cutting direction are arranged movable or moved and that the second sliding body is arranged to be movable relative to the first sliding body via at least one drive.

The plant preferably has an elongate machine frame, which is arranged substantially in line with the production direction of a baking plant, a sandwich forming station, a stacking station and interposed coating devices "in-line" in an industrial production line.

Preferably, the wafer blocks are stacked individually or stacked introduced into the first cutting station and cut. The cutting in the second cutting station can extend per cutting stroke on several waffle blocks. Preferably, in the second cutting station, two waffle blocks are cut at least partially per cutting stroke, so that the cut passes through an interface of two successively arranged wafer blocks per cutting stroke. Thus, in the second cutting station, a waffle block is pushed through the cutting area by the subsequent waffle block.

When cutting the wafer blocks, it must be ensured, in particular in the first cutting station, that the individual parts are not separated from each other after the cutting process, but are pressed against one another or further conveyed or transported against one another in block form.

In order to achieve the object according to the invention, it is proposed that two sliding bodies be present, wherein the second sliding body is made extendable relative to the first sliding body.

The first sliding body extends laterally to or in the region of the rear end side of the edge and supports the waffle block in this area. For cutting off the edge, the waffle block is at least partially pushed through the cutting area, in particular by the first sliding body. In this case, the lateral edges of the waffle block are separated and preferably removed by arranged behind the cutting edge Randabfallleitmittel. Just before the Randabfallleitmittel, especially just after the cutting area or just after the cutting body of the first slide body is stopped to prevent the first slide body collides with the Randabfallleitmittel. The second sliding body has exemptions, which are arranged substantially in the region of the cutting body and groove-like or cut-out along the cutting direction in the sliding body. As a result of these exemptions, the second sliding body can be moved at least partially through the cutting area, without a collision occurring between the second sliding body and the cutting bodies and possibly the edge waste guiding means. Due to this extendability, the waffle block can be supported until immediately in front of the edge waste guide along its entire rear end side or along the rear end side of the edge, in order in particular to prevent the rear edges from breaking off. Only to complete pushing or further transport of the wafer block stops the first sliding body and the second sliding body takes over the further promotion.

The second sliding body in particular has a lateral clearance for that cutting body which is adapted to cut off or trim the edge of the waffle block. By this exemption, the side edge of the second sliding body is preferably formed. The first sliding body is designed, for example, narrow or web-shaped and has a lateral extent, which corresponds approximately to the width of the edge or of the edge to be cut off. Optionally, a gap is provided between the lateral edge of the second sliding body and the first sliding body, which extends preferably similar or the same as the exemptions along the cutting direction of the front edge of the sliding body to the rear, so when partially pushing the sliding body through the cutting area of the sliding body not collided with the cutting body.

Optionally, the second sliding body is arranged or supported on the first sliding body. Optionally, the first sliding body comprises only lateral narrow extensions, which have a lateral width which corresponds approximately to the width of the edge. Optionally, the first sliding body and the second sliding body together form a sliding body that supports the waffle block substantially along its entire rear end face. Optionally, the first sliding body and the second sliding body together form a sliding body, which sufficiently supports the wafer block along its end face, so that no reduction in the efficiency of the manufacturing process occurs.

The second sliding body is preferably designed and / or arranged such that the waffle block can be moved through the cutting area and into the second cutting station. For this purpose, the exemptions in the second slide body are designed such that a complete pushing through of the wafer block by the cutting area and optionally a further promotion of the wafer block is made possible in a spaced-apart from the cutting area. This region spaced from the cutting region is located, for example, in the second cutting station.

In a further consequence, the invention will be further described on the basis of concrete exemplary embodiments and with reference to the figures.

1 shows a plant for producing end products by cutting waffle blocks, wherein the plant is an input station 22 , a cutting station 1 for cutting and / or cutting blocks and a dispensing station 23 for the final products.

About the input station 22 The waffle blocks, coming from a plant for the production of wafer blocks, direction cutting station 1 promoted. The present embodiment includes a first cutting station 26 and a second cutting station 27 , The input station or the conveying device of the input station is designed in particular as a belt or belt conveyor. In the input station, the wafer block along the first conveying direction 25 emotional. Preferably, the first conveying direction corresponds 25 essentially the direction along which the wafer blocks are moved during their manufacture.

The waffle blocks are then individually or stacked to the first cutting station 26 to hand over. The first cutting station 26 has a cutting direction 9 on, along which the waffle blocks or the waffle block is cut. The cutting direction preferably proceeds 9 essentially normal to the first conveying direction 25 , This results in a cutting across the first conveying direction 25 causes. The first cutting station includes a pusher 11 , This pusher 11 in this embodiment comprises a first sliding body 12 and a second sliding body 13 , Furthermore, at least one drive 10 provided over which the sliding body 12 . 13 along the cutting direction 9 can be moved. Optionally, the first cutting station, as in the present embodiment, for the first sliding body a first drive 19 over which the first sliding body along the cutting direction 9 can be moved. The second sliding body 13 also has a drive 10 namely, the second drive 20 on, which is designed in particular as a stand-alone drive.

This drive allows according to the present embodiment, a displacement of the second sliding body relative to the first sliding body. This shift is due to the second drive 20 driven and preferably extends substantially along the cutting direction 9 , The cutting station preferably comprises a conveying surface 5 , Along this conveying surface or on this conveying surface 5 lying, the waffle block is pushed by the sliding bodies.

The first cutting station 26 includes a cutting area 6 , In this cutting area 6 is a cutting body 7 intended. In particular, at least one cutting body 7 intended. At least two cutting bodies are preferred 7 provided, wherein a cutting body 7 for separating the left edge and a cutting body 7 is set up to separate the right edge. According to the present embodiments are several, in particular four cutting body 7 provided, which in addition to separating the edge also effect further cuts, so that the waffle block is divided into several parts when the waffle block entirely through the cutting area 6 pushed or transported. Preferably, each cutting body is designed as a cutting wire or cutting band. The cutting wires can be in a cutting frame 21 be provided and / or clamped. The cutting frame is preferably rigidly connected to the machine frame and possibly tilted so that the waffle block is pressed against the conveying surface during cutting. In the sliding bodies, in particular in that sliding body, through which the waffle block is pushed through the cutting area, are exemptions 14 intended. The exemptions 14 are provided laterally in that area in which the cutting body 7 are arranged so that the cutting body 7 when pushing through the waffle block through the cutting area in the exemptions 14 are insertable, without causing a collision between the sliding body and the or the cutting body (s) 7 comes. Then to the cutting area 6 are in the cutting direction 9 Randabfallleitmittel 32 intended. These are designed as curved plates in the present embodiment. The Randabfallleitmittel 32 serve to derive the cut edge of that part of the waffle block that is further processed into finished products. In particular, the Randabfallleitmittel 32 formed such that the separated edge when feeding the wafer block laterally and out of the plane of the conveying surface 5 is directed.

The first cutting station 26 is a second cutting station in this embodiment 27 downstream. The second cutting station 27 can be identical to the first cutting station 26 be executed, wherein the second cutting direction 28 the second cutting station 27 transverse to the cutting direction 9 the first cutting station 26 runs. Thereby, the waffle block can be cut in two different directions, in particular to form end products.

In the present embodiment, the second cutting station 27 a different configuration than the first cutting station 26 , Thus, the second cutting station comprises a second sliding device 30 that only comprises a sliding body. The second pusher 30 promotes the wafer block to be cut in a second cutting direction 28 , in particular by a second cutting bodies 29 provided second cutting area.

Spaced apart, preferably substantially parallel spaced, from the conveying surface 5 are preferably at least one, optionally two or more hold-down 31 intended. These have a distance to the conveying surface, so that the waffle block between the hold-down and the conveying surface fits and is guided if necessary, so that the hold-down can function as hold-down in the technical sense. In particular, the hold-down device serves as a hold-down against the cutting forces acting on the waffle block.

In the present embodiment, the wafer blocks are not necessarily conveyed individually through the cutting area of the second cutting station. Rather, according to the present configuration, a first waffle block or a first waffle block stack is conveyed into the first cutting station. There, the waffle block or waffle block stack is pushed by the pusher through the cutting area of the first cutting station and further conveyed to the second cutting station. In normal operation, at this time, there is a previous waffle block or waffle block stack in the second cutting station, partly from the second cutting body 29 is cut. In this case, the preceding waffle block or waffle block stack is advanced at least so far that the following waffle block or waffle block stack are introduced into the second cutting station can. For this, the second pusher is brought into a retracted position, so that there is enough space to accommodate the subsequent waffle block or waffle block stack. If the subsequent waffle block, which, like the preceding waffle block, has been cut in the first cutting station along the first cutting direction, is deposited in the second cutting station, the second pushing device is seated 30 in progress and pushes the subsequent waffle block together with the previous waffle block at least partially through the cutting area of the second cutting station. This pushes the second pusher 30 the following waffle block to the previous waffle block. As a result, the preceding waffle block is pushed completely through the cutting area of the second cutting station. The subsequent waffle block is only pushed so far through the cutting area of the second cutting station, that on the one hand another subsequent waffle block can be introduced into the second cutting station and on the other hand, that the second sliding device not with the second cutting bodies 29 collides and, where appropriate, the last strip of the subsequent waffle block is at least cut. In this position, the second sliding device is withdrawn again, so that a further subsequent waffle block can be introduced into the second cutting station.

In contrast to the first cutting station in which the wafer blocks or wafer block stacks are individually cut, in the second cutting station two wafer blocks or wafer block stacks are cut with a cutting stroke completely completely cutting the previous, already cut wafer block or waffle block stacks and the subsequent waffle block or waffle block stacks at least incised.

2 shows a detailed view of an oblique view of a system according to the invention. The plant and in particular the first cutting station are in a position in which the pusher 11 Direction cutting area 6 drove. Also in the second cutting station 27 is the second pusher 30 arranged in a middle position. In this middle position, for example, it is not possible to convey the waffle block from the first cutting station to the second cutting station. Such a position results for example when advancing the second sliding device 30 for pushing a waffle block through the cutting area of the second cutting device.

3 shows a detailed oblique view of a cutting station according to the invention. This includes a sliding device 11 , The pusher 11 includes a first sliding body 12 , as well as a second sliding body 13 , One of the sliding bodies, in particular the second sliding body 13 includes exemptions 14 , These exemptions 14 extend substantially slit-shaped from the front edge 16 of the second sliding body 12 along the cutting direction to the rear. The distance of the exemptions corresponds essentially to the distance of the cutting body 7 , The cutting body 7 are preferred as in a cutting frame 21 clamped cutting wires formed. The pusher 11 has at least one drive 10 on. This drive 10 is adapted and adapted to move the slide body (s) so that the waffle block can be slid through the cutting area. Preferably, two drives are provided according to this embodiment. The first drive 19 is set up, the first sliding body 12 along the cutting direction 9 to move. The first drive 19 is formed in all embodiments of the invention, for example, as a linear drive, which is below the conveying surface 5 is provided, but with an element protrudes through the conveying surface to the first sliding body 12 drive. The second drive 20 is adapted to the second sliding body 13 in the cutting direction 9 to move. Optionally, the drive 10 , in particular the second drive 20 , for moving the second sliding body 13 on the first sliding body 12 attached so that the second sliding body 13 over the second drive 20 opposite the first sliding body 12 can be extended or moved.

The second sliding body 13 has a side edge 15 on. In particular, the second sliding body 13 two side edges 15 on. The distance between these two side edges 15 corresponds substantially or is slightly smaller than the distance of the outermost two cutting body. Thus, the distance corresponds to the two side edges 15 essentially the width of the waffle block after the separation of the lateral edges, possibly less a small tolerance measure.

The first sliding body 11 preferably also extends into the region in which the edge of the uncut wafer block is arranged. The width of the first sliding body thus corresponds substantially to the entire width of the uncut wafer block, ie the width of the two edges plus the width of the edge-cut wafer block.

The side edges of the second sliding body are each of an exemption 14 limited, wherein the exemption is limited only on one side by the second sliding body, so this lateral release 14 at the same time the side edge 15 of the second sliding body 13 forms. The exemptions 14 are formed such that the second sliding body at least partially through the cutting area 6 can be pushed without the second sliding body 13 with the cutting bodies 7 collided. When pushing through are the cutting body 7 thus in the exemptions 14 arranged the second sliding body. By retracting the second sliding body 13 also leave the cutting body 7 the exemptions 14 ,

Optionally, for lateral guidance of the waffle block, a first guide surface 34 and a second guide surface 35 intended. These guide surfaces may be formed, for example, by bar-shaped or wall-shaped elements which are essentially in the cutting direction 9 are formed following. By this lateral guide elements of the waffle block is guided laterally during the cutting process. In particular, the guide surfaces protrude 34 and 35 from the conveying surface 5 out and / or beyond these, for example, or at least the height of the waffle block zuzuschneid. As a result, the area for receiving the waffle block, ie the area between the two guide surfaces 34 . 35 , a trough-shaped form, in which the waffle block is introduced via the conveying device.

4a shows a schematic representation of the pusher 11 , The pusher 11 includes a first sliding body 12 and a second sliding body 13 , In the illustrated position of 4a are the leading edge of the second sliding body 16 and the leading edge of the first sliding body arranged substantially in alignment or completing each other. In this case, an edge is formed by the first sliding body and the second sliding body, which runs substantially rectilinearly and / or the edge of the waffle block to be pushed, in particular the rear end side 18 of the waffle block, is modeled. At the rear end 18 of the waffle block, the two sliding bodies engage together to push the waffle block.

For example, there is the pusher 11 for pushing the waffle block towards the cutting area and into the cutting area in this position. Just before the cutting bodies, just before the cutting area 6 or just before the Randabfallleitmittel the first sliding body is stopped.

4b shows a further position in which the second sliding body 13 opposite the first sliding body 12 is arranged in an extended position. Just before the Randabfallleitmittel the first sliding body is stopped. The second sliding body is via the second drive 20 moved further and in particular with respect to the first sliding body 12 extended so that the waffle block can be pushed through the cutting area. In this case, the second sliding body 13 exemptions 14 on, especially in the field of cutting bodies 7 are provided to prevent a collision between the pusher and the cutting bodies 7 to avoid. The illustrated position of 4b For example, corresponds to a position in which the waffle block completely through the cutting area 6 pushed through. The first sliding body 12 is in a retracted position, in particular stopped just before the Randabfallleitmittel. The second sliding body projects beyond the first sliding body in the cutting direction 9 , As a result, the waffle block can also be conveyed further into the second cutting station.

In all embodiments, a stacking magazine 36 be provided. This stacking magazine 36 includes movable extensions, in particular plate-shaped bodies, which are coupled via a moving device movable with the machine frame. Through this stacking magazine several wafers blocks coming from the Wafflebackmaschine and in particular from the input station 22 to be stacked on top of each other. So one waffle block can be stacked over the other. The stacking preferably takes place in such a way that the wafer blocks lie congruently against one another on their flat sides or lie on top of each other. For example, two, three, four, five, six, seven, eight or more wafer blocks may be stacked on top of each other. This waffle block stack can subsequently be cut by the first cutting station and optionally by the second cutting station.

In all embodiments, it can thus be provided that a waffle block stack is provided instead of a single waffle block. Thus, instead of a single waffle block, a single waffle block stack may be inserted into the cutting stations.
