Description
10~`~7fi3 The present invention relates to a fish processing machine provided with a conveyor system passing a working path of fish processing tools and including fish entraining means.
An apparatus for the transport of f~sh through a fish processing machine is known (see, for example, DE-PS 11 54 913).
This known apparatus has, in the course of many years, proved its suitability for the conveying of herring. It enables a slip-free conveying of fish of different size and shape and also leaves the region of the flanks and belly flaps free so that, for example, the rib cuts can be performed with greater certainty and with the least loss of fish flesh. This apparatus has, however, the disadvantage that it is impossible to arrange tools and guides, such as for example back filleting knives or separating knives, acting from the rear side of the fish. Furthermore, for wider and round-backed fish, it is necessary to exchange the conveyor for another provided with grippers suitable for this purpose.
It is an essential object of the present. invention to adapt processing machines to different cross sections of fish and to enable processing steps which are directed to improve the yield independent of constructional facts, the machine being adaptable to larger and thicker fish without essential constructional alterations, while it may be easily provided with tools or guides effective from the back.
According to the invention there is provided a fish processing machine provided with a conveyor system passing ~`` lOg4763 a processing path of fish processing tools and including fish entraining means, the conveyor means comprising two endless V-blet means arranged in such a manner as to run along- i - side each other in the same direction, the fish entraining means each consisting of two adjacently positioned gripping members, each of the V-belt means carrying.spaced there?long a respective one of the t~o associated gripping members of each of the fish entralning means, a respective first guide rail to laterally support at least along a portion of the processing path each one of the two associated gripping.members of a respective one of the entraining means, and a further .
guide rail-arranged to be disposed between respectively associa-ted gripping members of the containing means.
. By using two V-belt running alongside each other the machine may easily be adapted to process varying fish and to be provided with additional tools and guides.
According to an advantageous embodiment, the machine comprises endless and flexible V-belt means and first and second pulley members each provided with two adjacently position-ed V-shaped grooves, each groove supporting a respective one of the V-belt means, and means to drive one of the two pulley members. Thus, a synchronous runnlng of the two associat-ed gripping members is assured. According to the other emdo-diments of the invention each of the gripping members is provided at that one of its surface opposite the surface facing the respectively associated grippins member with a shoulder for support by the upper portion of the associated first guide rail, while the machine.may also .
10~763 comprise means to press associated gripping members of the entraining means towards the associated first guide rails at least along the processing path, in the region of each processing tool and the means to press being resiliently yieldable in a direction away from the associated first guide rails. This allows for achieving the necessary resiliency or for withstanding the load exerted on the conveyor in the region of each tool.
In order to assure a synchronous deflection in the associated gripping members on the passage of a fish and also a change of their spacing, at least part of the means to press may comprises a plurality of presser members each provided with presser roller means comprising two adjacently positioned V-shaped grooves, whereas the means to press may comprises a plurality of presser members,lat least part of the presser members comprising two presser rollers positioned adjacent each other by means of a roller bolt and each provided with a respective V-shaped groove.
Advantageously, the gap between the first guide rails in the region of one or more presser members may be enlarged and the further guide rail may be correspondingly widened.
Thereby, a machine embodying the i~vention is adaptable to particular kinds of processing ~r to particular kinds of fish.
In a machine further embodying the invention, the further guide rail is provided with at least one passage to receive processing tool means an~/or guide means, so that 3~' guides or tools may be arranged in a simple manner for action on the fish from its backside.
Embodiments of the present invention will now be more particularly described, by way of example, with re-ference to the accompanying schematic drawings, in which:-Fig. 1 shows a fish processing machine embodying theinvention;
Fig. 2 shows a partial section through the machine shown in Fig. 1 in the region of a presser roller; and Fig. 3 shows a section corresponding to Fig. 2 with splayed gripper halves.
Referring now to the drawings, in the fish processing machine of Fig. 1, a working path 19 is arranged in a vertical plane and fish are conveyed along this in the direction of the arrow with the belly down and the head end forward. Tools ~not shown) required for the processing of the fish axe arranged underneath the working path 19 and a conveyor 1 for seizing the fish by their backsides is arranged above the working path 19. The conveyor 1 comprises two endless V-belts 11 and 12, which run beside each other and which are driven by a drive pulley 13 rotating about a horizontal driving axle 131 and deflected by a deflecting pulley 14 rotating about a horizontal deflecting axle 141.
The drive pulley 13 carries on its circumference two V-grooves 132 and 133 lying beside each other and the deflecting pulley 14 correspondingly carries two V-grooves 142 and 143, which are so arranged that the right hand ~0~
V-belt 11 circulates in the V-grooves 132 and 142 and the left hand V-belt 12 circulates in the V-grooves 133 and 143.
Each of the two V-belts 11 and 12 carries on its external side gripper halves 21 and 22, which are arranged in a close sequence and which together form an entraining member.
The backs of the fish are centred each time in the prismatic recesses 24 of the entraining members. Each gripper half 21 is each time fastened to the V-belt 11 and each gripper half 22 is fastened to the V-belt 12. As shown in Figs. 2 and 3, each of the two symmetrically shaped gripper halves 21 and 22 has an internal surface 211, an external surface 212 parallel thereto, a shoulder 214 protruding outwardly from the latter and an entraining surface 213 running inclined from the external surface 212 to the internal surface 211 and forming the prismatic recess 24. The entraining surfaces 213 are interrupted by slots 215 reaching up to the external surfaces 212 in order to be able to seize the fish securely for their entrainment.
A guide rail 17 is arranged locally fixed in the vertical plane for the guidance of the gripper halves 21 and 22 and respectively associated with a right hand guide rail 15 and a left hand guide rail 16, which support the gripper halves 21 and 22 from the outside and at the same time serve to bear the shoulders 214. To make possible an adaptation to different back heights of the fish to be processed, the gripper halves 21 and 22 running closely above the working path 19 can yield upwardly. In order that ~hey yield synchronously, a presser member 18 is arranged above each processing tool and constructed as a presser lever 181 10~4763 pivotable about a locally fixed pivot axle 182 and carrying a roller bolt 188 at its free end. Arranged on this roller bolt 188 is either a presser roller 184 of a part of the presser member and provided with two V-grooves 186 and 187 lying beside each other, or two presser rollers 185 lying beside each other and each provided with a V-groove 189 and arranged to rotate freely. It is possible by the arrangement of the two presser rollers 185 to enlarge the gap 23 shown in Fig. 2 between the two guide rails 15 and 16 to the size of a gap 25 in correspondence with Fig. 3. To this end, the width 171 of the rail 17 in Fig. 2 is enlarged to the width 172 of the Fig. 3. As a result thereof, an enlargement of the prismatic recess 24 results and makes possible the reception of the back of a larger fish.
Advan~ageously, a fish processing machine embodying the invention is adaptable without significant changes to larger and wider fish and makes possible the arrangement of tools or guides effective from the back.
