Description
2~~292z A device for the automatic reQUlated transfer of fish to a fish processing machine BACKG&OUND OF THE INVENTION
1. Field of the Invention The invention concerns an automatic apparatus for arranging and uniformly orientating fish prior to automatically feeding the fish to a processing machine.
2. Prior Art The automation of such an apparatus, i.e. the fully automatic operation from supplying the fish in bulk, to feeding the fish to, and processing the fish in, the processing machine without manual intervention, is problematic due to the varying features of this essentially natural product, such as size, consistency, fidelity to species characteristics and also to the desired throughput yield.
An apparatus provided for this purpose is described in EP-A-0 166 782. This apparatus comprises a feed conveyor, a longitudinal orientation or aligning device and a device for achieving the correct belly-back position and includes as a central element an imaging system arranged downstream of the longitudinal orientation device for supplying image information enabling each fish to be placed in the optimal position for decapitation. To this end, the imaging system monitors the alignment of each fish and also controls the movement of points which influence the path of the fish so that each fish is individually handled. In other words, when the longitudinal or head-tail orientation of the fish is incorrect, the fish is rejected and when the lateral or belly-back orientation is incorrect, i.e. the fish is facing 2~~2922 in the correct direction, but lying on the wrong side, it is steered onto a separate turning path.
Error analysis has shown that a primary requisite for the optimal functioning of such an apparatus is that the fish are separated accurately enough to enable them to be handled singly and.so preclude the possibility of mutual interference during the orientation or alignment process. In this context, it is also indispensable that the transfer of the fish to the processing machine can be reliably monitored; this is also significant with regard to the efficiency of machine, which requires that the number of fish handled by the machine and expelled due to incorrect orientation be kept to a minimum.

The sensor means can preferably be formed as reflex sensors, whereby the reflected signal is evaluated according to its intensity. Due to the dark colour of the fish back and the light colour of the fish belly, the incorrect position of the fish can be determined by the received sequence of minimum and maximum reflection intensities and the position can be corrected by activating the turning means. To this end, a turning lever can be controlled to move against a turning disk so that the misorientated fish is subjected to a turning moment and is turned 180° about its longitudinal axis.

Tn accordance with Figs. 1 and 2, the conveyor 1 comprises a travelling grating 1.1 having a conveying surface 1.2 essentially formed of several adjacent grating bars 1.3 aligned side by side in the conveying direction. As shown in Fig. 2, the grating bars 1.3 are mutually connected by yokes 1.4 and 1.5 such that the grating surface is formed of two meshed grating parts. Each grating part is connected via an arm 1.6 and 1.7, respectively, to a pair of synchronously rotating crank shafts 1.8, while the arms 1.6 and 1.7 of the I
~ ~ T~gzz grating parts are engaged with cranks 1.9 and 1.10, respectively, which are mutually offset by 180°. The conveying surface 1.2 is formed with an upwards slant in the feed area 1.11 and with a downwards slant in the discharge area and terminates above the rectifying channel 2.1 of the longitudinal orientation device 2. The width of the conveying surface 1.2 is designed to correspond roughly with the width of the rectifying channel 2.1, whilst the edge bars 1.12 and the middle bar 1.13 of the conveying surface 1.2 extend beyond the other grating bars 1.3. In a multi-path embodiment of the travelling grating 1.1, a shoulder element 1.14 mounted on the inner edge bar 1.12 serves as the limit with respect to the neighbouring conveying surface. A guide face 1.15 is arranged in the region of the extension of the edge bar 1.12 on the latter's underside and terminates below the longitudinal axis of the rectifying channel 2.1.
The rectifying channel 2.1 of the longitudinal orientation device 2 comprises a U-shaped section and is driven in a suitable manner to oscillate longitudinally. In order to eliminate the inertia forces in the four-path embodiment, alternate channels are connected together via a two-arm connecting rod 2.2, which is pivotally mounted about a central vertical axis 2.3, as shown in Fig. 5. The channels are then operated such that the outer channels are driven in an opposite direction to the inner channels.
The rectifying channel 2.1 is provided in its feeding area with a guide rail 2.5 which divides the supporting surface 2.4 longitudinally in two partial paths. The guide rail 2.5 extends beyond the rear end of the rectifying channel 2.1 and terminates in a dividing wedge 2.6. A chute 3.1, which is a component of the turning device 3 is arranged below the end of the rectifying channel 2.1. As shown in Figs. 1 and 3, the turning device 3 comprises a brush cylinder 3.3, driven to rotate about a horizontal axis 3.2. The chute 3.1 is arranged 21T292~
to form a tangent with the underside of the brush roller 3.3.
The chute 3.1 leads into a guide cover 3.4, which encompasses the rear surface of the brush roller 3.1 and extends beyond the latter's peak to descend towards the supporting surface 2.4 of the rectifying channel 2.1 and terminate in an inclined guide surface 3.5. A helical guide web 3.6 (Fig. 4) is located on the inner side of the guide cover 3.4 and comprises an end piece 3.7 which terminates adjacent, but not in contact with, the dividing wedge 2.6 of the guide rail 2.5 of the rectifying channel 2.1.
The device 4 for aligning the fish in a uniform lateral position by placing them all onto the same side is associated with the discharge side of the rectifying channel and comprises opposing guide faces 4.2, which form a guide channel 4.1. At the entrance of the guide channel 4.1, the guide faces 4.2 are provided with a contour 4.3 to deflect surplus fish. At the discharge end of the channel 4.1 the guide faces 4.2 are designed to twist in the same direction so that the channel section causes the fish to turn about their longitudinal axis as they pass through it.
The guide channel 4.1 is succeeded by a transfer channel 4.4, which adjoins the device 5 for singly receiving the aligned fish and transmitting the fish in accordance with a predetermined timing. (Fig. 6). The device 5 comprises a guide channel 5.1 of U-shaped section of which the base surface is formed by the conveying run 5.2 of an endless conveyor belt 5.3. The conveyor belt 5.3 is guided around a deflection roller 5.4 and a driving pulley 5.5 and is equipped on its conveying surface with a rows of adjacent spikes which are arranged on the belt such that the ratio of the pitch of the spikes to the circumference of the driving pulley 5.5 being an integer. The driving pulley 5.5 is driven by an elliptical wheel gear 5.6 and coupled with the same such that the spikes 5.7 have a minimum speed on z emerging onto the conveying run 5.2, and a maximum speed as they disappear below the conveying run.
A catch flap 5.8, which can be pivoted about a frame-fixed axis in the direction movement of the conveyor belt 5.3 against a spring 5.9 is arranged in the area where the spikes 5.7 emerge. The catch flap 5.8 is formed as a tunnel, within which a pre-stop 5.10 is arranged to yield resiliently in a vertical plane.
The guide channel 5.1 of the timing device 5 terminates above the transverse conveyor 6. The latter is preferably identical to a trough conveyor of a fish heading and filleting machine, for example, and comprises a chain of troughs 6.1 arranged immediately adjacent one another for receiving the fish singly. Each trough 6.1 comprises a body recess 6.2 and a head recess 6.3, separated from one another by a gap 6.4. A
stop rail 6.5 is located at the edge of the tranverse conveyor 6 adjacent the head recess opposite the mouth of the guide channel 5.1 against which the fish heads abut as they fall from the guide channel 5.1.
The transverse conveyor 6 is designed to transport the fish through the measuring means 7 (Fig. 7). The latter comprise a reflex sensor 7.1 arranged above the path of the transverse conveyor 6 and comprising an emitter 7.2 and receiver portion 7.3 and an additional receiver 7.4 which is located below the conveyor 6 at the level of the gap 6.4 and forms a light barrier 7.5 with the emitter portion 7.2. To this end, the emitter portion 7.2 is arranged to oppose the additional receiver 7.4, whilst the receiver portion 7.3 is focussed on an observation point located on the axis of the light barrier 7.5 at a distance above the supporting surface 6.6 equal to the mean fish width.
' 10 The measuring means are connected to the turning mechanism via a non-shown control unit (Fig. 8). The turning mechanism includes, as shown in Fig. 8, a driven reversing disk 8.1 which is arranged between the body recesses 6.2 and the head recesses 6.3 and whose periphery extends slightly above the supporting surface. The referring disk 8.1 is driven to run together with the transverse conveyor 6 and at roughly double the speed. The reversing disk 8.1 opposes a retaining member 8.2, which penetrates into the gap 6.4 and is formed as a dragging pivot lever which can be pushed resiliently upwards against the force of a spring 8.3 by the fish.
The retaining member 8.2 is pivotally mounted about a frame-fixed axis 8.4 and carries a hook-shaped turning lever 8.5 about its free end. This lever 8.5 is hingeably mounted to the retaining member 8.2 to pivot in the same pivot plane.
The turning lever 8.5 has a concave capture face 8.6 arranged to oppose the reversing disk 8.1 and extend over that part of the reversing disk periphery which penetrates above the supporting surfaces 6.6 of the troughs 6.1. A rod 8.7 connects the turning lever 8.5 with a crank 8.8 which has a crank axis corresponding to the axis 8.4 of the retaining member 8.2. The crank 8.8 can be pivoted by means of a pneumatic cylinder 8.9 The operation of the above described device is as follows.
The fish are introduced into the feed area 1.11 of the conveyor 1 by means of a suitable charging device, which generally delivers the fish in batches, and land initially on the conveying surface 1.2 of the travelling grating 1.1.
This travelling grating, by virtue of the opposing two-phase lifting-advancing and sinking-rectracting oscillatory motion of the grating parts, causes the pile of fish to be converted into a single layered stream of fish. Due to the laminating action of the conveying surface 1.2 formed by the grating bars 1.3, the fish become essentially aligned longitudinally and are fed in this position to the delivery end of the travelling grating 1.1. At this point, the fish fall through the gaps formed between the extensions of the edge and middle bars 1.12, 1.13, which allow the fish to pass lengthwise only, into the rectifying channels 2.1 positioned below. The transfer is controlled by the guiding face 1.15 such that the fish fall into one of the channel portions separated by guide rail 2.5 in the rectifying channel 2.1. As a result of the oscillatory movement of the rectifying channel 2.1, the fish are retained in their longitudinal orientation while advanced through the channel portions, although only those fish facing in the direction of movement, i.e. those fish which are in a swimming position, are advanced down the slope. Since the fish may land in the rectifying channel facing either in or against the direction of movement, this means that those fish facing against the feed direction are advanced up the slope of the rectifying channel 2.1 and into the turning device 3 head first. These fish are then caught by the brush roller 3.3 and returned to the rectifying channel 2.1 in the correct orientation. These turned fish are transferred to the free channel portion of the rectifying channel 2.1 by means of the action of the guide web 3.6. Thus the fish are advanced downwardly in the channel 2.1 in two separate fish streams free from mutual interference and fed head first into the alignment device 4 to correct their lateral orientation.
In the orientation device 4, the two streams of fish are combined and by using the sectional geometry of the fish, the fish are initially placed upright on their bellies and then uniformly brought into a position on one of their sides. Any surplus fish can be deflected out of the fish stream over the contours 4.3 and then reintroduced into the process again by a suitable conveyor.
In the following timing device 5, a first fish comes to rest with its head against the front end of the catch flap 5.8 and ' 2112922 is initially stopped. Any second fish which might be pushed over the first fish will be held back by the pre-stop 5.10.
The first undermost fish will then be engaged and advanced by the spikes 5.7 on the conveyor belt 5.3, which emerge upwards into the guide channel 5.1. At this point, the catch flap 5.8 is dragged along with the fish until it is released. Due to the position of the pivot axis of the catch flap 5.8, the height of the pre-stop 5.10 above the supporting surface remains essentially unchanged so that any second fish lying on top will be held back throughout this process. After the first fish is pulled forwards, the second fish is pushed by the conveying force of the rectifying channel 2.1 to take the place of the first fish until the following spike 5.7 emerges and engages this fish also. The engagement of the fish by the spikes 5.7 occurs at low speed, which is then increased so that initially, relatively low inertia forces act on the fish.
The transfer of the fish to the transverse conveyor 6 occurs at maximum speed and in synchronism with the position of the troughs 6.1.
Since fish is a natural product, it is not possible to obtain completely accurate and error free uniform lateral orientation, so some of the fish will inevitably be lying on the wrong side. The positions of the fish lying in the troughs are thus checked. This takes place in the measuring station 7, and is initiated by the interruption of the light barrier 7.5 by the fish. Subsequently a reflex measurement is made, during which the reflected signal is evaluated according to its intensity. Thus in the embodiment shown in Figs. 1 and 7 a signal sequence comprising a minimum and then a maximum represents a fish lying on its left side, since this means that the fish is being advanced with its darker, more light absorbing back leading. When an incorrect fish 2x72922 orientation is determined the turning mechanism 8 arranged downstream is activated when the fish has reached the corresponding position.
As shown in Figs. 9a) to c) this is performed by the turning lever 8.5, which upon activation by the pneumatic cylinder 8.9 is caused to pivot into the path of the fish to be turned (Fig. 8), to engage the fish by its leading side and force it against the turning disk 8.1. Since the peripheral speed of the turning disk 8.1 is higher than that of the transverse conveyor 6, the fish is turned by a rolling motion about its longitudinal axis. This is further promoted by providing the turning disk with a roughened frictional surface.
For reasons of clarity, the drawings show only a single stream feed apparatus. However, in practice it has been found that a four stream apparatus ensures the necessary teed throughput for a subsequent processing machine. The drawings also show a particular functional order, although this may be altered without departing from the spirit of the invention.
For example, it is conceivable that the orientation device 4 be integrated into the operating area of the timing device 5.
These transfer means are preferably arranged such the fish are protected from any damaging forces even at high processing frequency. This is specifically achieved by engaging the fish in the waiting position at a relatively low speed and progressively increasing the speed towards the feeding end so that damaging acceleration forces are avoided.
To correct possible laterally misaligned fish, i.e. fish lying on the wrong side, transverse conveyors serving as feeding conveyors are provided with means for turning these fish, the means being preferably activated when required by optical sensor means. The sensor means can preferably be formed as reflex sensors, whereby the reflected signal is evaluated according to its intensity. Due to the dark colour of the fish back and the light colour of the fish belly, the incorrect position of the fish can be determined by the received sequence of minimum and maximum reflection intensities and the position can be corrected by activating the turning means. To this end, a turning lever can be controlled to move against a turning disk so that the misorientated fish is subjected to a turning moment and is turned 180° about its longitudinal axis.

A chute 3.1, which is a component of the turning device 3 is arranged below the end of the rectifying channel 2.1. As shown in Figs. 1 and 3, the turning device 3 comprises a brush cylinder 3.3, driven to rotate about a horizontal axis 3.2. The chute 3.1 is arranged 21T292~
to form a tangent with the underside of the brush roller 3.3.
The chute 3.1 leads into a guide cover 3.4, which encompasses the rear surface of the brush roller 3.1 and extends beyond the latter's peak to descend towards the supporting surface 2.4 of the rectifying channel 2.1 and terminate in an inclined guide surface 3.5. A helical guide web 3.6 (Fig. 4) is located on the inner side of the guide cover 3.4 and comprises an end piece 3.7 which terminates adjacent, but not in contact with, the dividing wedge 2.6 of the guide rail 2.5 of the rectifying channel 2.1.
The device 4 for aligning the fish in a uniform lateral position by placing them all onto the same side is associated with the discharge side of the rectifying channel and comprises opposing guide faces 4.2, which form a guide channel 4.1. At the entrance of the guide channel 4.1, the guide faces 4.2 are provided with a contour 4.3 to deflect surplus fish. At the discharge end of the channel 4.1 the guide faces 4.2 are designed to twist in the same direction so that the channel section causes the fish to turn about their longitudinal axis as they pass through it.
The guide channel 4.1 is succeeded by a transfer channel 4.4, which adjoins the device 5 for singly receiving the aligned fish and transmitting the fish in accordance with a predetermined timing. (Fig. 6). The device 5 comprises a guide channel 5.1 of U-shaped section of which the base surface is formed by the conveying run 5.2 of an endless conveyor belt 5.3. The conveyor belt 5.3 is guided around a deflection roller 5.4 and a driving pulley 5.5 and is equipped on its conveying surface with a rows of adjacent spikes which are arranged on the belt such that the ratio of the pitch of the spikes to the circumference of the driving pulley 5.5 being an integer. The driving pulley 5.5 is driven by an elliptical wheel gear 5.6 and coupled with the same such that the spikes 5.7 have a minimum speed on z emerging onto the conveying run 5.2, and a maximum speed as they disappear below the conveying run.
A catch flap 5.8, which can be pivoted about a frame-fixed axis in the direction movement of the conveyor belt 5.3 against a spring 5.9 is arranged in the area where the spikes 5.7 emerge. The catch flap 5.8 is formed as a tunnel, within which a pre-stop 5.10 is arranged to yield resiliently in a vertical plane.
The guide channel 5.1 of the timing device 5 terminates above the transverse conveyor 6. The latter is preferably identical to a trough conveyor of a fish heading and filleting machine, for example, and comprises a chain of troughs 6.1 arranged immediately adjacent one another for receiving the fish singly. Each trough 6.1 comprises a body recess 6.2 and a head recess 6.3, separated from one another by a gap 6.4. A
stop rail 6.5 is located at the edge of the tranverse conveyor 6 adjacent the head recess opposite the mouth of the guide channel 5.1 against which the fish heads abut as they fall from the guide channel 5.1.
The transverse conveyor 6 is designed to transport the fish through the measuring means 7 (Fig. 7). The latter comprise a reflex sensor 7.1 arranged above the path of the transverse conveyor 6 and comprising an emitter 7.2 and receiver portion 7.3 and an additional receiver 7.4 which is located below the conveyor 6 at the level of the gap 6.4 and forms a light barrier 7.5 with the emitter portion 7.2. To this end, the emitter portion 7.2 is arranged to oppose the additional receiver 7.4, whilst the receiver portion 7.3 is focussed on an observation point located on the axis of the light barrier 7.5 at a distance above the supporting surface 6.6 equal to the mean fish width.
' 10 The measuring means are connected to the turning mechanism via a non-shown control unit (Fig. 8). The turning mechanism includes, as shown in Fig. 8, a driven reversing disk 8.1 which is arranged between the body recesses 6.2 and the head recesses 6.3 and whose periphery extends slightly above the supporting surface. The referring disk 8.1 is driven to run together with the transverse conveyor 6 and at roughly double the speed. The reversing disk 8.1 opposes a retaining member 8.2, which penetrates into the gap 6.4 and is formed as a dragging pivot lever which can be pushed resiliently upwards against the force of a spring 8.3 by the fish.
The retaining member 8.2 is pivotally mounted about a frame-fixed axis 8.4 and carries a hook-shaped turning lever 8.5 about its free end. This lever 8.5 is hingeably mounted to the retaining member 8.2 to pivot in the same pivot plane.
The turning lever 8.5 has a concave capture face 8.6 arranged to oppose the reversing disk 8.1 and extend over that part of the reversing disk periphery which penetrates above the supporting surfaces 6.6 of the troughs 6.1. A rod 8.7 connects the turning lever 8.5 with a crank 8.8 which has a crank axis corresponding to the axis 8.4 of the retaining member 8.2. The crank 8.8 can be pivoted by means of a pneumatic cylinder 8.9 The operation of the above described device is as follows.
The fish are introduced into the feed area 1.11 of the conveyor 1 by means of a suitable charging device, which generally delivers the fish in batches, and land initially on the conveying surface 1.2 of the travelling grating 1.1.
This travelling grating, by virtue of the opposing two-phase lifting-advancing and sinking-rectracting oscillatory motion of the grating parts, causes the pile of fish to be converted into a single layered stream of fish. Due to the laminating action of the conveying surface 1.2 formed by the grating bars 1.3, the fish become essentially aligned longitudinally and are fed in this position to the delivery end of the travelling grating 1.1. At this point, the fish fall through the gaps formed between the extensions of the edge and middle bars 1.12, 1.13, which allow the fish to pass lengthwise only, into the rectifying channels 2.1 positioned below. The transfer is controlled by the guiding face 1.15 such that the fish fall into one of the channel portions separated by guide rail 2.5 in the rectifying channel 2.1. As a result of the oscillatory movement of the rectifying channel 2.1, the fish are retained in their longitudinal orientation while advanced through the channel portions, although only those fish facing in the direction of movement, i.e. those fish which are in a swimming position, are advanced down the slope. Since the fish may land in the rectifying channel facing either in or against the direction of movement, this means that those fish facing against the feed direction are advanced up the slope of the rectifying channel 2.1 and into the turning device 3 head first. These fish are then caught by the brush roller 3.3 and returned to the rectifying channel 2.1 in the correct orientation. These turned fish are transferred to the free channel portion of the rectifying channel 2.1 by means of the action of the guide web 3.6. Thus the fish are advanced downwardly in the channel 2.1 in two separate fish streams free from mutual interference and fed head first into the alignment device 4 to correct their lateral orientation.
In the orientation device 4, the two streams of fish are combined and by using the sectional geometry of the fish, the fish are initially placed upright on their bellies and then uniformly brought into a position on one of their sides. Any surplus fish can be deflected out of the fish stream over the contours 4.3 and then reintroduced into the process again by a suitable conveyor.
In the following timing device 5, a first fish comes to rest with its head against the front end of the catch flap 5.8 and ' 2112922 is initially stopped. Any second fish which might be pushed over the first fish will be held back by the pre-stop 5.10.
The first undermost fish will then be engaged and advanced by the spikes 5.7 on the conveyor belt 5.3, which emerge upwards into the guide channel 5.1. At this point, the catch flap 5.8 is dragged along with the fish until it is released. Due to the position of the pivot axis of the catch flap 5.8, the height of the pre-stop 5.10 above the supporting surface remains essentially unchanged so that any second fish lying on top will be held back throughout this process. After the first fish is pulled forwards, the second fish is pushed by the conveying force of the rectifying channel 2.1 to take the place of the first fish until the following spike 5.7 emerges and engages this fish also. The engagement of the fish by the spikes 5.7 occurs at low speed, which is then increased so that initially, relatively low inertia forces act on the fish.
The transfer of the fish to the transverse conveyor 6 occurs at maximum speed and in synchronism with the position of the troughs 6.1.
Since fish is a natural product, it is not possible to obtain completely accurate and error free uniform lateral orientation, so some of the fish will inevitably be lying on the wrong side. The positions of the fish lying in the troughs are thus checked. This takes place in the measuring station 7, and is initiated by the interruption of the light barrier 7.5 by the fish. Subsequently a reflex measurement is made, during which the reflected signal is evaluated according to its intensity. Thus in the embodiment shown in Figs. 1 and 7 a signal sequence comprising a minimum and then a maximum represents a fish lying on its left side, since this means that the fish is being advanced with its darker, more light absorbing back leading. When an incorrect fish 2x72922 orientation is determined the turning mechanism 8 arranged downstream is activated when the fish has reached the corresponding position.
As shown in Figs. 9a) to c) this is performed by the turning lever 8.5, which upon activation by the pneumatic cylinder 8.9 is caused to pivot into the path of the fish to be turned (Fig. 8), to engage the fish by its leading side and force it against the turning disk 8.1. Since the peripheral speed of the turning disk 8.1 is higher than that of the transverse conveyor 6, the fish is turned by a rolling motion about its longitudinal axis. This is further promoted by providing the turning disk with a roughened frictional surface.
For reasons of clarity, the drawings show only a single stream feed apparatus. However, in practice it has been found that a four stream apparatus ensures the necessary teed throughput for a subsequent processing machine. The drawings also show a particular functional order, although this may be altered without departing from the spirit of the invention.
For example, it is conceivable that the orientation device 4 be integrated into the operating area of the timing device 5.
