Description

Device and method for skinning fish fillets

description

The invention relates to a device, designed and set up for skinning fish fillets, comprising a feed device for feeding skin-side fish fillets tail-forwards in the direction of a center conveyor, the

Central conveyor for conveying the fish fillets in the direction of a separating device and for conveying and supporting the fish fillets during the skinning process, the

Separating device for separating the skin from the fish fillet, wherein the separating device is arranged to form a separating gap spaced from the center conveyor, and a discharge device for conveying the skinned fish fillets.

The invention further relates to a method for skinning fish fillets, comprising the steps of feeding tail-side fish fillets by means of a feeder device in the direction of a center conveyor,

Transferring the fish fillets to the center conveyor, by means of which the fish fillets are conveyed in the direction of a separating device, separating the skin from the fish fillet by means of a separating device, wherein the fish fillets during the skinning process of

Center conveyors are promoted and supported, and separate removal of the skinned fish fillets by means of a discharge on the one hand and the separated skin by means of the center conveyor on the other.

Such devices and methods are used in the fish processing industry to separate the skin from fish fillets, or more specifically from fillet. The fish fillets, on which the skin is still on one side, are transported with the skin side down and tail in front. The feeding of the fish fillets takes place by means of a feed device. The fish fillets are transferred from the feeder device to a center conveyor, commonly referred to as

Mitnehmerwalze is formed. When transported on the entrainment roller, the fish fillets are separated by the separating device or a knife through, which is arranged above the center conveyor. Here, the skin is guided below the knife through the separating gap, while the filet is guided above the knife, so that in this way the skin is separated from the meat. The fish fillet (meat) is therefore removed separately from the skin. The skinned fish fillets, so the filet, are using the

Discharged conveyor. The skin (remnants) and the tail end connected to the skin are usually carried down by the center conveyor. During skinnings, it is important that the skin-side down fish fillets are kept secure and level during the separation process for meaningful cutting results. For this purpose, the surface of the center conveyor, on which the fish fillets lie during the skinning process, is structured. For the design and structuring of the lateral surface of the center conveyor various solutions are proposed in the prior art. For example, in DE 28 44 241 a device for skinning

Discloses fish fillets, in which the lateral surface of the entrainment roller, the so-called skinning roller, for the supporting and transporting recording of the skin side of the fish fillets has transversely extending recesses in the form of narrow grooves. DE 43 37 478 A1 describes a device in which the

Promotional surface of the skinning roller is provided with a granular corundum coating. DE 199 62 440 A1 proposes a toothed roller for transporting the fish fillets during the skinning process. In the solutions mentioned, there is the disadvantage that the quality of the surface of the skinned fish fillet is greatly impaired by the laying of the fish fillets on the skinned process on profiled or structured surfaces of the carrier / skinning rolls or conveyor belts as the center conveyor. In order to keep the fish fillets on the center conveyor during the skinning operation and to enable the separating cut altogether, additional pressing elements are sometimes used, e.g. in the form of pressure rollers required, which on the one hand increases the design effort and on the other hand further reduces the product quality, since the products are pressed during the skinning in the uneven profile / structure of the center conveyor. A wavy cut result not only has qualitative impairments but also leads to a yield loss.

Another method and a device for skinning fish fillets provides according to WO 93/22929 to form the driver roller as a freezing drum, so that the fish fillets during the skinning process with the skin side on the Freeze the lateral surface of the freezer drum and thereby hold it. In addition to the above-mentioned disadvantages of a deterioration in product quality due to the structured surfaces of the driver rollers as a center conveyor, the latter solution has a significant energy requirements, on the one hand

costly and on the other hand e.g. is not feasible on fishing and processing vessels.

The invention is therefore an object of the invention to provide a device that ensures the fish fillets gentle and exploitative strong skinning. Furthermore, the object is to propose a corresponding method.

This object is achieved by a device having the features mentioned in the fact that the center conveyor is associated with at least one element for fixing the tail end zugeförderter fish fillets on the center conveyor, wherein the element for fixing from an open position for receiving and

Releasing the tail end into a closed position to hold the tail end and pulling the fish fillet along the tail end along the tail end

Separating device and vice versa formed movable and is set up. The or each tail end fixing member may be formed separately from the center conveyor, but is preferably connected to or part of the center conveyor. By the element for fixing the tail end ensures that each fish fillet in the promotion along the separator, ie the actual skinning process, by the pulling movement - unlike pushing or pushing - kept under tension, so that the prerequisite for a smooth cut given is. In other words, the

According to the invention that each fish fillet is pulled smooth during skinning. On additional pressing elements, such as pressure rollers or the like, can therefore be omitted. Furthermore, the embodiment according to the invention results in the center conveyor not requiring any explicit profiling / structure. As a result, the combination of features of claim 1 results in that during the skinning process, a level cut is achieved, so that a high-quality fish fillet is produced. The smooth skinning cut also achieves an improved yield. A preferred embodiment is characterized in that the device is designed and set up for automatic skinning of fish fillets and a Control and / or regulating device comprises, at least the

Feed device, the center conveyor and the element for fixing the

Tail are connected. Through the control and / or

Control device, the individual conveyor speeds of the conveyor on the one hand and the operation of each element to fix the tail end individually and automatically matched to each other, so that the device ensures high productivity with consistently high quality.

Advantageously, the center conveyor is a driven carrier roller, wherein the surface of the carrier roller is formed substantially structureless. in the

In this context, essential means that the surface or

Jacket surface of the driver roller is formed free of a conscious or explicitly shaped profiling / structuring. In other words, the surface or lateral surface of the carrier roller is formed smoothly in the context of production-related tolerances. As a result, during the skinning operation, an optimum underlay is created for the fish fillets resting on their skin side, which, in conjunction with the pulling transport, fixes the tail end along the fish skin

Separation device leads to particularly high-quality and high-yield skinning cuts.

A particularly expedient development is characterized in that the element for fixing the tail end comprises a clamping element for clamping the tail end. A clamping element, so a kind of tail clamp, is a particularly simple and above all secure training of fixation, which can be opened in the same way again. That is, for receiving the tail end, the tail clamp can be moved quickly and easily to an open position and to a closed position for holding and pulling the tail end, respectively. Thus, on the one hand the product to be won (skinned fish fillet) is spared because the tail is discarded anyway as a committee.

On the other hand, a high clock rate can be achieved in skinning.

Particularly preferably, the center conveyor is assigned on its circumferential surface at least one clamping bracket as a clamping element, which in the closed position in

Substantially flush with the surface of the center conveyor. With such a clamp, a linear or even planar system can be achieved at the tail end, a secure and firm fixing during the skinning process ensures. By flush closing the clamp in the closed position of the clamp can be pulled with the clamped tail of the fish fillet with the skin through the separation gap. In other words, the fish fillet can be pulled with its skin side safely and collision-free under the separator, so that a knife of the separator between the skin and the fish fillet can dive, such that the skinned fish fillet above the separator and the tail end with the attached skin can be carried down. An advantageous embodiment is characterized in that the clamping bracket is pivotally formed about a pivot axis S, wherein the pivot axis S is aligned parallel to a rotation axis R of the center conveyor. By the pivoting of the clamp short ways to open and close are ensured. Short pivoting means correspondingly short action times, whereby the clock performance of the device is improved. Furthermore, the short pivoting paths allow a quick and reliable change between opening and closing of the clamp, which is the one for the inclusion of fish fillets at the tail end before skinning and the other for the release of the

Tail ends with the hanging skin residue after skinning is important.

Conveniently, the clamp is directed against the conveying direction F of the fish fillets on the feeder device, such that the open position of the clamp is accessible by operating the clamp in the rotational direction of the center conveyor and the closed position of the clamp by pressing the clamp against the rotation direction of the center conveyor. This means that the opening of the clamping bracket in the open position is directed against the conveying direction F of the fish fillets on the feeder device, so that the tail ends are forcibly conveyed into the opened clamping bracket.

In a preferred embodiment, the center conveyor is associated with a plurality of elements for fixing the tail end. The example of the driver roller two or more elements are arranged distributed for fixing uniformly over the circumference of the driver roller. In a single element for fixing, the circumference of the driving roller is at least equal to the length of the fish fillets to be processed. For multiple elements to fix the distance between two elements to Fix at least as long as the length of the fish fillets to be processed. By the plurality of elements for fixing the clock power of the device can be increased. Advantageously, the feed device and the discharge device each comprise endless, driven belt conveyors. The belt conveyors allow a particularly fast and safe feed and discharge and are particularly suitable for interacting with the driver roller to ensure a smooth transfer from conveyor to conveyor. The feed device and discharge device may optionally also include so-called transfer rollers in order to shorten the distance between the center conveyor.

A particularly preferred development is characterized in that it comprises at least one monitoring means for monitoring at least the

Transition region comprises from the feed device to the center conveyor, wherein the monitoring means is connected to the control and / or regulating device. Monitoring means may optionally be used e.g. Light barriers,

Sensors or the like. Particularly preferably, this includes

Monitoring means an optical camera, by means of u.a. the arrival of fish fillets on the center conveyor on the one hand and the provision of an open and free element for fixing on the other hand can be monitored. The information and data obtained by the camera may be processed within the control and / or regulating device and used to control and / or regulate the connected components.

The object is also achieved by a method with the above-mentioned steps by first picking up and fixing the tail end of the fish fillet on the center conveyor by a fixing element and pulling the fish fillet along the cutting device during the skinning process from the tail-end fixing element the tail end is released again after the skinning process by the element for fixing.

Preferably, when a fish fillet arrives on the center conveyor, the fixing element is moved to an open position to receive the tail end of the fish fillet conveyed to the center conveyor, and then the fixing element is moved to a closed position around the fish fillet with its skin at the tail end pull through the separating gap formed between the center conveyor and the separator.

Particularly advantageous, the element for fixing moves circumferentially with the center conveyor.

Advantageously, at least the transition region is monitored by the feed device to the center conveyor by means of at least one monitoring means.

Particularly preferably, the method is carried out with a device according to one of claims 1 to 10.

The resulting from the device according to the invention advantages apply in the same way for the inventive method, which is why reference is made to avoid repetition of the corresponding passages.

It is expressly understood that features that are summarized in the claims and / or the description and / or the drawings or described in a common embodiment , even functionally independently can further develop the apparatus 10 described above. The feed device 1 1, the center conveyor 13 and the discharge conveyor 15 (generally and collectively also referred to as conveyors) are driven in rotation. The drive of the conveyors can be done via (not explicitly shown) stepper motors, servo motors or other suitable drive means, namely continuously and / or stepwise or clocked. In particular, the center conveyor 13 can be driven continuously or discontinuously. The

Drive speed of the conveyors can be the same for all conveyors. Since all conveyors are driven individually, the drive speeds may also be different. In the illustrated

Embodiment comprises the feed device 1 1 next to a belt conveyor 17 as a feed conveyor a transfer roller 18, which bridges the distance between the belt conveyor 17 and the center conveyor 13. On the transfer roller 18 can also be dispensed with, especially if the diameter of the drive and / or pulleys of the belt conveyor 18 is kept very small, so that a narrow radius in the transition region between the belt conveyor 17 and the center conveyor 13 is formed. The discharge device 15 optionally also comprises a belt conveyor 19 as a discharge belt. The conveying devices can all lie in a common conveying plane.

Preferably, however, the conveying devices are arranged offset in the conveying direction F in each case downward. In other words, the conveying level is the

Feeding device 1 1 slightly above the conveying plane of the center conveyor 13 and the conveying plane of the center conveyor 13 again slightly above the conveying plane of the discharge conveyor 15. The separator 14 is in the embodiment shown above the center conveyor 13. Above means in this

Connection that the separator 14 from the top of the on the

Center conveyor 13 funded fish fillet 12 meets or between the skin of the fish fillet 12 and the skin adhering fillet dips when the fish fillet 12 is conveyed through with the skin side through the separating gap T.

The separating device 14 comprises at least one (skinned) knife. The knife can be stationary and rigid, so immobile, designed as a standing blade. The knife can also be formed oscillating, with an oscillating

Knife types are combined, for example, an oscillating knife for the gate and a fixed knife for the cut. The bleed can also be done by a basically fixed knife that performs a single stroke transverse to the conveying direction F for bleed. The or each

Cutting edge of the knife is directed against the conveying direction F of the fish fillets 12, so that the fish fillets 12 are inevitably conveyed into the effective range of the knife. Furthermore, the knife preferably has a phase on the skin-facing side in order to prevent cutting of the skin.

Preferably, the device 10 is designed and set up for automatic skinning of fish fillets 12. To this end, the device 10 comprises a control and / or regulating device 20, to which at least the feed device 11, the center conveyor 13 and the tail end fixing element 16 are connected (see, for example, FIG. The control and / or regulating device 20 may comprise a CPU, by means of which recorded and / or determined data and information can be processed and used for control and / or regulation commands. Furthermore, the control and / or regulating device 20 may also include storage media as well as input and output modules and in particular a display.

In the preferred embodiments according to the figures 1 to 4 is the

Center conveyor 13 a driven cam roller 21, wherein the surface of the cam roller 21 is formed substantially structureless. The driver roller 21 is driven in rotation about the axis of rotation R. With the structureless surface or lateral surface of the driver roller 21, a smooth support for the fish fillets 12 is described, which forms an abutment for the separator 14. However, in further embodiments, the surface / lateral surface may also be at least partially provided with a structure or a profiling or the like. In alternative embodiments (see, e.g., Figure 5), the center conveyor 13 is e.g. formed as a circulating belt conveyor 22 which is driven to rotate about the rotation axis R. The belt conveyor 22 is preferably a chain conveyor or a modular chain belt. The tail end fixing member 14 is shown in FIG

Embodiment, a clamping element 23 for clamping the tail end. A such clamping device may be formed separately from the center conveyor 23, but is preferably associated with the center conveyor 13 or part thereof. In the embodiment according to FIGS. 1 to 3, the carrier roller 21 is known as

Middle conveyor 13 on its peripheral surface associated with a clamping bracket 24 as a clamping element 23 which terminates in the closed position substantially flush with the surface of the driver roller 21. Substantially flush in this context means that the clamping bracket 24 may also protrude slightly over the peripheral surface of the center conveyor 13, as long as a collision-free promotion is guaranteed. Particularly preferably, the clamping bracket 24 is in the closed position to the other slightly below the peripheral surface of the center conveyor 13th

In the embodiment according to FIG. 4, the carrier roller 21 is as

Middle conveyor 13 on its peripheral surface two clamping brackets 24 assigned as a clamping element 23. In the embodiment according to FIG. 5, the belt conveyor 22 is assigned a clamping bracket 24 as a clamping element 23. Optionally, the

Mitnehmerwalze 21 and any other central conveyor 13 also be associated with more than two such clamping elements 23. In addition or instead of the clamping elements 23, the elements 16 may also have other positive and / or frictional and / or non-positive components for fixing, for example in the form of Fixierdornen. The clamping elements 23 and other elements 16 for fixing are e.g. actuated via a cam control as an actuating means. Optionally, the clamping elements 23 may also be pneumatically or by suitable drive means, e.g. a servomotor, are operated. The electrical and / or electronic

Actuating means are preferably connected to the control and / or regulating device 20.

Each clamping bracket 24 is pivotally formed about a pivot axis S, wherein the pivot axis S parallel to a rotation axis R of the center conveyor 13th

is aligned. Based on the embodiment of Figures 1 to 4, the pivot axes S of the clamping bracket 24 are parallel to the axis of rotation R of

Cam follower 21 aligned. Based on the embodiment of Figure 5, the pivot axis S of the clamping bracket 24 is aligned parallel to the axes of rotation R of the belt conveyor 22. The pivot axes S are offset radially to the

Rotation axis R arranged. Instead of the pivoting mechanism, other mechanisms for opening and closing the fixing member 16 may be used serve, eg folding or sliding mechanisms and linear actuated and movable elements 16.

The or each clamp 24 is directed against the conveying direction F of the fish fillets 12 on the feed device 1 1, such that the open position of the clamping bracket 24 by operating the clamping bracket 24 in the rotational direction of the center conveyor 13 and the closed position of the clamping bracket 24 by pressing the

Clamping bracket 24 opposite to the direction of rotation of the center conveyor 13 is reached. In the open position (see, for example, Figures 1 and 3 and 5), an opening O is formed to receive the tail end of a fish fillet 12. The opening O is directed against the conveying direction F, so that the tail ends are automatically guided into the opening O. The clamp 24 may be formed smooth on the inside, which faces the fish fillet 12. Preferably, the inside of the clamp strap 24 has a structure or profiling or is at least roughened to ensure a secure fit in the closed position (see, e.g., Figures 2 and 4).

A particularly preferred embodiment is shown in FIGS. 3 and 4. The device 10 comprises at least one monitoring means 25 for monitoring at least the transitional area from the feed device 11 to the first

Monitoring means 25 an optical camera 26, with the aid of the entry of fish fillets 12 in the region of the center conveyor 13 on the one hand and the position or the state of the center conveyor 13 and the clamping elements 23 (Is the clamp in the open position or in the closed position? Are there any remains left on the middle conveyor 13 or in the clamp?) Is monitored and recorded. The or each monitoring means 25 is connected to the control and / or

Control device 20 connected to the processed data and information can be processed. Instead of the camera 26 or in addition to this, the monitoring means 25 may also include sensors, light barriers, distance measuring elements, counters and the like, by means of which in particular the interaction of feed device 1 1, center conveyor 13 and element 16 can be monitored for fixing. The control and / or regulating device 20 can be connected to the individual components of the device 10 via lines or without wires, for example via radio, Bluetooth or the like. The control and / or Control device 20 may also be connected to an internal or external network.

As can be seen in particular from FIGS. 3 to 5, the device 10

Elements 27 for stripping the separated from the fillet and by the

Center conveyor 13 downwardly conveyed skin, which rests on the center conveyor 13. This element 27 may e.g. a single scraper roll 28 (see, e.g., Figure 3). In addition to or in lieu of the wiper roller 28, e.g. Also, a nozzle member 29 (see, eg, Figures 4 and 5) may be arranged, the means of air and / or water jet after opening the elements 16 for fixing the skin (with the tail end) from the element 16 and from the center conveyor 13 before the element 16 for receiving a tail end in the

Transition region between the feed device 1 1 and the center conveyor 13 is moved.

The method principle according to the invention is explained in more detail below with reference to the drawing:

The fish to be processed is initially on a conventional

Filleted fish fillet machine. The resulting fish fillets 12 are manually or mechanically fed to the device 10 for skinning. In the device 10, the fish fillets 12 are deposited on a feed device 11, by means of which the fish fillets 12 lying on their side of the skin extend ahead in the direction of a tail

Center conveyor 13 are promoted. The fish fillets 12 are transferred to the center conveyor 13, by means of which the fish fillets 12 are conveyed in the direction of a separating device 14. With the separator 14, the skin is separated from the fish fillet 12, wherein the fish fillets 12 are promoted and supported by the center conveyor 13 during the skinning process. The separation of the skin takes place by conveying the fish fillets 12 with their skin side from the center conveyor 13 through the separating gap T formed between the separating device 14 and the center conveyor 13. After the skinning process, a separate removal of the skinned fish fillets 12 by means of a discharge device 15 on the one hand and the separated skin by means of the

Center conveyor 13 on the other. For the skinned process, the separator 14 dips between the skin and the filet associated with the skin. As a result, the skinned fish fillet 12 across the separator 14 away on the

Passed discharge conveyor 15 and conveyed away from this, while the skin is guided through the separating gap T and conveyed away from the center conveyor 13 down. According to the invention, the tail end of the fish fillet 12 is first picked up and fixed on the center conveyor 13 by a fixing member 16, and the fish fillet 12 is pulled along the cutter 14 during the skinning operation by the tail-fixing member 16, the tail end being after the complete skinning process of the Element 16 is released for fixing again. That is, each fish fillet 12 is gripped and held by the member 16 upon arrival on the center conveyor 13, so that the fish fillet 12 is drawn toward the separator 14 as it is being conveyed through the center conveyor 13 such that the separator 14 enters the fish fillet 12, so that the skin side of the center conveyor 13 is further actively carried down, while the fillet pushed over the separator 14 - above the separator 14 along this sliding along - and is conveyed away from the discharge device 15. To release the tail end with the skin thereon, the element 16 is opened after the complete skin peeling process to the

Release tail end. The adhesive on the center conveyor 13 skin can then be removed by means of an element 27 for stripping from the center conveyor 13. This can e.g. by scraping by means of a scraper roller 28 or by means of a

Nozzle element 29 take place.

Upon arrival of a fish fillet 12 on the center conveyor 13, the fixing member 16 is moved to an open position to move the tail end of the on

Center conveyor 13 zugeförderten fish fillets 12 record. When the tail end is sufficiently conveyed into the opening O, for example about 10-20mm in length, the fixing member 16 is then moved to a closed position to allow the fish fillet 12 at the tail end to pass between the center conveyor 13 and the separator Pull 14 formed separating gap T through. More specifically, the fish fillet 12 is moved through the area of action of the separator 14, such that a knife of the separator 14 dips into the fish fillet 12 and exerts the skinning process by the movement of the center conveyor 13. The skin follows the circular trajectory of the cam roller 21st In the event that, for example, the belt conveyor 22 is provided as a center conveyor 13 to feed the fish fillets 12 of the separator 14, the skin follows the path of movement of the belt conveyor 22, while the fillet is pushed onto the discharge device 15 and conveyed away from this. In order to ensure the skin skinning process throughout, the fixing element 16 moves circumferentially with the center conveyor 13. This means that the tail end remains fixed until the separator 14 has completed the skinning process. The skinning process can be continuous or clocked. Particularly advantageously, the movement of the fish fillets 12 by the device 10 takes place cyclically. This means, for example, in the event that the center conveyor 13 is associated with a single element 16 for fixing, that the center conveyor 13 rotates in steps of one complete revolution. In other words, then rotates as a driver roller 21 in steps of 360 °. The scope of

Mitnehmerwalze 21 is then at least as large as the length of the fish fillets to be skinned 12. In the event that two elements 16 are provided for fixing, rotates the cam roller 21 in steps of 180 °. The distance between the two elements 16 is then at least as long as the length of the fish fillets 12 to be skinned.

Preferably, at least the transition region from the feed device 1 1 to the center conveyor 13 is monitored by means of at least one monitoring means 25. In other words, over the stated range, e.g. an electronic

Measuring device or a camera 26 arranged, the extraction of

Information for influencing and controlling the skinning process is used. More specifically, by the monitoring means 25, the incoming tail end can be recognized. Further, it can be recognized when the tail end is sufficiently deep in the opening O of the fixing member 16 to close the member 16. With the monitoring means 25 can be further detected whether the element 16 is ready to receive a tail end, or whether there are still skin residues or the like in the element 16, which prevent a recording or at least impair.

Particularly preferably, the method is carried out with a device 10 according to one of claims 1 to 10, as described in detail above.
