Description

Method and device for removing the meat from halved meat Coconuts. The coconuts are already being gutted in such a way that the hollow meat side of the nut half held by a gripper device of inside a number of radially arranged knives of a head as it rotates in the meat penetrate up to the inner wall of the hard shell and so the meat evenly capture and replace. Here, only strips with an unfavorable rhombic cross-section are used obtain. The new thing is that the knives radially up to first pressed into the meat to the shell and only then rotated, whereby they then the meat of the Break off the shell. This procedure falls the shape of the stripes looks better than the known ones.

Above all, however, the pitting takes place in a significantly shorter time, so that the new device is much more powerful.

The drawing shows an exemplary embodiment of the subject matter of the invention reproduced.

Fig. I shows a longitudinal section through the machine with it removed Coat before the beginning of the movement.

Fig.2 is also a longitudinal section, rotated 9o, this time at the end the cutting movement.

Fig.3 shows the attachment hood for the fruit seen from above.

Fig., L likewise seen from below. Fig 5 is the transmission for turning the cutter head.

Fig. 6 shows the guide ring for the knife shafts seen from above.

At the bottom of the machine frame i is first of all the shaft 2 for the step lever ; stored. A traverse .l is attached to the frame, which is used for guidance the bumper 5 and used to support the gear shafts 6; above is the guide ring ; attached for the knife shafts. Next, the frame is used for storage for the rotatable Aufsetzhaube 8 and to the bearing g for the fruit holding device. To put on the fruit is a dome to at the top of the Aufsetzhaube 8, which in their Size roughly corresponds to the inner curvature of the pulp. That is held previously split fruit by the holding device fixed in the bearing 9, which is shown in a hand lever i i, which is also designed as a gripper, and two further gripper arms 12 consists, all three of which are coupled to one another by interlocking tooth segments are. If the hand lever i i is pressed down, they move at the same time the gripper string 12 down and encircle the fruit from the outer (bast; Side and keep the shell of the lugs 13 of the Aufsetzhaube in their Location on the dome i o backed fruit.

If the fruit is held by the hand lever, this happens Cutting the meat into strips and loosening them by pressing down the Foot lever 3; this one stroke is sufficient to cut the meat of the copran nut and then detach from the hard shell. During the first half of this stroke the radially arranged knives penetrate the meat from the inside to the hard one Peel and cut the meat into pieces; during the second half of the stroke, the entire cutting device and the attachment hood move around the longitudinal axis The machine turned something, which removes the previously cut meat from the hard Shell is sheared off.

If you let go of the foot pedal again. so goes this and with it also return the machine to its starting position.

On the shaft 2 of the foot pedal; First, the control arm sit wedged 1 4 for moving the bumper 5 causing the cutting movement and second right: and to the left of it the tooth segment arms 15 for rotating the for loosening machine parts serving the meat.

At the beginning of the movement; Starting position) is the foot lever; approximately vertical and the control arm 14 is placed approximately vertically; the latter has one Recess 21 in which a pin 16 of the bumper 5 engages. In this recess 21 is around a pin 1; rotatable a control tongue i 8 of such a shape, that between her and the inner edges of the recess 21 of the pin 16 of the bumper can move. The pivot 1; the control tongue is carried outwards and thereon an arm 19 with a pendulum weight 2o attached so that the tongue 18 always tries to turn in the direction of the clock hand.

In the initial position: the control pin 16 of the bumper in the - deepest position of the recess 21, closest to your foot lever. While of the first half stroke of the step lever, the control pin 16 moves on the 3 upper side of the control tongue and slides up to about the middle of the recess, he has moved upwards according to the shape of the tongue and at the same time with it him the bumper 5; this has reached its highest level. The second half Stroke of the foot lever, the control pin 16 slides on the left half of the with the control arm 1 4 continuously rotating to the right control tongue 18; thereby sets the left end of the tongue on the lower wall of the recess as soon as the Pin 16 over pivot 1; the control tongue has passed. Another one Lifting of the safety rod 5 does not take place during this second half of the stroke, because the left half of the tongue in the so rotated position has an approximately horizontal path for the control pin i! @ forms.

The bumper 5 for the movement of the knife receives theirs on the one hand Guide in the traverse q., On the other hand at its lower end, which is divided into a fork shape is and the shaft 2 includes. The rod 5 needs a recess above the crossbeam, a piece of pipe 22 sits loosely on this exactly fitting, in its A piston 23 is movably seated on the upper part, the shaft 2 5 of which is cross-shaped at the top Knife 26 carries. In the tube is located between the rod 5 and the piston 23 as an elastic connection a spring 24. The shafts 28 of the radially arranged Knife 27 sit, held by a split pin, all around in cutouts of the flange 3o of the pipe section 22 and are carried by springs 29, which are on the flange prop up. A second row of knives 3 i sit on shafts 32 that are attached to the shafts 28 of the outer row of knives 27 are articulated. The shafts 32 are spring loaded 33 attached to the piston 23 are pushed outward; on the shafts 32 springs 34 are again attached, which press the mesh 27 outwards. The shafts 32 lean against the back of the knife 27, the shafts 28 are supported with lugs 35 against the inclined inside of the guide ring 7.

If the bumper 5, as described above, goes up during the first half stroke, the knife blades 25, 28 , 32 are pushed up with their knives, the lugs 35 slide on the guide ring, along the entire rod unfolds at the same time under the pressure of the springs 33, 34. The knives emerge through the guide slot 36 from the attachment dome until they hit the inner wall of the shell.

With the second half stroke, the meat is now loosened by the cutter head and the attachment hood rotate and split off the meat. the Toothed segments 15 transmit the rotation of the step lever shaft 2 to the gearwheels 37 of the gear shafts 6. However, these gears 37 are mounted on the shafts 6 in such a way that that they can rotate loosely on the shafts 6 during the first half stroke and only hit against drivers of shafts 6 during the second half stroke and so be coupled. On the shafts 6 further gears 38 are keyed with Tooth segments 39 of the flanges 3o of the knife carrier are in engagement, and also further above the gears 4o, which in turn have toothed segments 41 of the attachment hood 8 are engaged.

At the beginning of the second half stroke, the shaft 6 and so begins the cutter head and the attachment hood to rotate and rotate until the downward going The stroke of the foot pedal is complete and the machine is in the position shown in Fig. 2 has taken. The pin 16 has now left the control tongue in its free Position has swung back. By releasing the pressure on the foot pedal, the Return the machine to its starting position under the influence of the return weights 42 (Fig. i). With this decrease, the pin 16 slides completely on the lower wall of the recess to the right, lifting the right wing of the control tongue, which after its passage falls down again.

Half the coconut shell is now removed after opening the grippers 11, 12; the meat slides down from the bowl on the attachment hood and falls into one gutter running around the machine casing.
