    There is a fruit press for citrus fruits with a press head (4) connected to a lifting drive (5), which has two receiving matrices (10) arranged on both sides of a knife (14) and can be pivoted in opposite directions via parallel shafts (11) between an upper picking position and a lower pressing position. for each one fruit half, and with two punches (18) described, which cooperate with the receiving matrices (10) of the press head (4). In order to provide advantageous construction conditions, it is proposed that the lifting drive (5) acts on the press head (4) by means of a compression spring (21) via a compression spring.

    专利说明:

    The invention relates to a fruit juicer for citrus fruits with a press head connected to a lifting drive, comprising two receiving matrices for each fruit half, which are arranged on both sides of a knife and can be pivoted in opposite directions by means of parallel shafts between an upper picking position and a lower pressing position with two punches which cooperate with the receiving dies of the press head.
    Fruit juicers in which the pressing tools are formed from fixed lower punches and receiving dies cooperating with these punches which are pivotable between an upper picking position for the citrus fruits and a lower pressing position (WO 2013/038039 A1) provide construction advantages in terms of width because the receiving matrices are pivoted back and forth in opposite directions only between the receiving position and the pressing position and do not rotate in opposite directions. When the receiving dies are pivoted downward into the pressing position, the citrus fruits are halved with the aid of a knife arranged between the receiving dies, so that the half-fruits in the two receiving dies are pressed in the lower pressing position against the punches, which penetrate into the receiving dies. By the Hubtrieb the penetration depth of the stamp in the Aufnah¬mematrizen the press head and thus the extent of the pressure is given.For this reason, in such fruit presses a different thickness of the fruit peel must be disregarded, so citrus fruits with respect to the clearance between the punches and the receiving matrices However, if the skins are too thin, they may be insufficiently squeezed, but fruits with shells that are too dry in this connection can cause the fruit press to become overloaded.
    The invention is therefore based on the object, a fruit juicer for citrus fruit to design that independent of the shell thickness, complete
    Squeezing the citrus fruits can be guaranteed without having to worry about overloading the fruit juicer.
    Based on a fruit press of the type described above, the invention achieves the stated object in that the lifting drive acts on the press head with a pressing force via a pressure spring.
    By switching on a compression spring, via which the pressing pressure is exerted on the Pressen¬ head, advantageously the respective shell thickness be¬reflecting tolerance compensation is made possible, wherein the pressing force is determined by the Vor¬spannung the compression spring. This means that the citrus fruits regardless of the thickness of their shells with a given pressing force can be completely pressed, because the maximum pressing force conditional Vor¬spannung the compression spring hardly because of the thickness differences of the shells and therefore comparatively small suspension travel differences changes. But this also the burden of the fruit press of the shell thickness is independent and remains in an envisaged, permissible size.
    The measure to provide a compression spring between the lifting drive and the press head is not dependent on the structural design of the lift drive or the compression spring. Nevertheless, particularly simple design conditions result if the lifting drive comprises a crank mechanism whose connecting rod has two sections which can be displaced relative to one another in the axial direction and which are connected to one another via a compression spring. The two connecting rod sections can thus be displaced against the force of the compression spring when the punches press against the edges of the fruit halves.
    In the drawing, the subject invention is shown, for example. It shows
    1 shows a citrus fruit juicer according to the invention in a section perpendicular to the shafts of the receiving matrices in the upper receiving position of the receiving matrices,
    Fig. 2 is a section along the line II-II of Fig. 1 and
    Fig. 3, the connecting rod of the crank mechanism designed as a lift mechanism fragmentary in the field of compression spring in a schematic longitudinal section in a larger scale.
    The illustrated citrus fruit juicer comprises a frame 2 enclosed by a housing 1 forming a height-wise guide 3 for a press head 4. This press head 4 is driven along the guide 3 with the aid of a lifting drive 5, which according to the exemplary embodiment is designed as a crank drive with a crank 6 and a connecting rod 7 articulated on the crank 6, which becomes effective as a pull rod in the selected arrangement during the pressing stroke. To drive the lifting drive 5 is an electric motor 8 with connected Winkelge¬triebe 9.
    In the press head 4 are two receiving matrices 10 gela¬gert on parallel shafts 11, which carry a drive pinion 12 which meshes with the side of the frame 2 attached toothed rack 13 so that upon displacement of the press head 4 along the guide 3 rolling on the racks 13 Drive pinion 12, the Aufnah¬mematrizen 10 during the press stroke from the illustrated upper Aufnahme¬ position in a lower pressing position and pivot during the idle stroke of the lower press position back into the receiving position.
    Between the two receiving matrices 10, a knife 14 is fastened to the frame 2, with the aid of a knife carrier 15. The citrus fruits, which are fed to the receiving matrices 10 via a feed channel 16, after cutting during the counter-rotating Abschwenk¬ Movement of the receiving matrices 10 can not slide out of the receiving matrices 10 schwer¬ force caused, the receiving matrices 10 on the Pres¬senkopf 13 slideways 17 assigned to the fruit halves.
    Below the receiving matrices 10, two punches 18 are provided in the frame 2, which cooperate with the receiving matrices 10 in the lower pressing position. The support of the punches 18 takes place via a carrier 19, which is fastened to the guide 3 in the exemplary embodiment. When the receiving matrices 10 loaded with the fruit halves are lowered onto the punches 18 during the pressing stroke of the press head 4, the fruit halves are squeezed between the punches 18 and the receiving matrices 10. The squeezed juice is collected on the carrier 19 forming a discharge within a juice compartment and can be removed via a stopcock 20. The pressed-out shells of the fruit halves are lifted off the punches 18 during the pivoting back of the receiving matrices 10 into the starting position and conveyed into a collecting container, which is not shown for reasons of clarity.
    By means of the lifting drive 5, the pressing stroke of the press head 4 is structurally determined. However, different shell thicknesses of the citrus fruits to be squeezed out can be taken into consideration, the press head 4 is acted upon by the lifting drive 5 via a compression spring 21 which brings about a tolerance compensation with respect to the different shell bottoms. In an embodiment of the lifting drive 5in the form of a crank mechanism, advantageous constructions result in this connection if the connecting rod 7 is subdivided into two axially displaceable sections 22 and 23, which are supported against each other via the compression spring 21, as shown in FIG is shown. The compression spring 21, which is in the form of a disk spring package, is provided in a cylinder 24 connected to the section 23 of the pin 7 cylinder and acts on a piston 25 whose piston rod is formed by the other portion 22 of the connecting rod 7, which passes through the plate spring assembly of the compression spring 21 to pressurize the compression spring 21 during the pressing stroke in the sense of an extension of the connecting rod 7. If the cups are pressed against the pressing ram 18 during pressing of the fruit halves, which exceeds the pretension of the compression spring 21, the sections 22 and 23 of the connecting rod 7 are replaced 3 pulled apart against the force of the compression spring 21, so that the maximum pressing force is determined by the compression spring 21. This means that the halved citrus fruit can be completely squeezed out without having to worry about overloading the fruit juicer.
