DETAILED DESCRIPTION

(9) FIGS. 1a, 1b, 1c, 2a, 2b and 2c disclose a wire cutter apparatus 1 according to a first embodiment wherein each of said figures show the different steps for cutting and crimping a wire 2.

(10) FIG. 1a shows the wire cutter apparatus 1 just before cutting and crimping a wire 2 and the final result of the wire 2 with a crimped leading end 3a and a crimped rear end 3b can be seen in FIG. 2c.

(11) The wire cutter apparatus 1 comprises a first side wall 4 and an opposing second side wall 5. It furthermore comprises a third side wall 6 in between the first side wall 4 and the second side wall 5. A fourth side wall 9 is disposed in between the first side wall 4 and the second side wall 5 and opposes the third side wall 6. The side walls 4, 5, 6, 9 define an interior space A.

(12) The first side wall 4 and the second side wall extend parallel to a longitudinal feeding axis X.

(13) A wire feeding opening 7, as indicated in FIG. 1b, is provided in the third side wall 6 for feeding the wire 2 from an exterior space B into the interior space A. The exterior space is defined as the space lying outside or outwards of the side walls opposed to the interior space A.

(14) A feeding direction of the wire 2 defines the longitudinal feeding axis X. Typically, the wire 2 is inserted or fed along the longitudinal feeding axis and transported along this axis X towards a first rotatable wire guiding tube 10.

(15) The first rotatable wire guiding tube 10 is configured for receiving the leading end 3a of the wire 2. For this purpose, the first rotatable wire guiding tube 10 comprises a wire entrance 11a at one end of said tube 10.

(16) The first rotatable wire guiding tube 10 is a hollow tube and is able to receive the wire 2 and transport the wire 2 through the tube 10 from one end to the second end, i.e. from the wire entrance 11a to a wire exit 11b.

(17) The first rotatable wire guiding tube 10 is rotatable around the wire entrance 11a. In other words, a pivot point of the first rotatable wire guiding tube 10 is disposed at its wire entrance 11a. Preferably, the first rotatable wire guiding tube 10 rotates in a horizontal plane. The horizontal plane is spanned by the longitudinal feeding axis and a lateral axis Y. The lateral axis Y defined by the line of shortest distance between a first crimping press 15 and the longitudinal feeding axis X. Seen from the longitudinal feeding axis X, the lateral axis Y points to the first crimping press 15 and is perpendicular to the longitudinal feeding axis X.

(18) By rotating the first rotatable wire guiding tube 10 the wire exit 11b is movable from a first wire exit position coinciding with the longitudinal feeding axis X to a second wire exit position spaced away from the longitudinal feeding axis X and vice-versa. The wire exit 11b therefore describes a circular path when being moved.

(19) FIG. 1a shows the wire exit 11b of the first rotatable wire guiding tube 10 in its first wire exit position. As can be seen, the wire exit 11b lies on the longitudinal feeding axis X.

(20) FIG. 1b shows the wire exit 11b of the first rotatable wire guiding tube 10 in its second wire exit position. As can been, the wire exit 11b is spaced away from the longitudinal feeding axis X and is adjacent the first crimping press 15. The first crimping press 15 is suitable for receiving the leading wire end 3a of the wire 2 when the wire exit 11b is in the second wire exit position as can be seen in FIG. 1b. The first crimping press 15 is spaced away from the longitudinal feeding axis X. The first crimping press 15 is configured to crimp the leading wire end 3a.

(21) After crimping the leading wire end 3a, the first rotatable wire guiding tube 10 is rotated from the second wire exit position to the first wire exit position as shown in FIG. 1c.

(22) FIG. 1c shows that the wire exit 11b is adjacent to a wire entrance 21b of a second rotatable wire guiding tube 20. This allows the wire 2 to be guided from the first rotatable wire guiding tube 10 into the second rotatable wire guiding tube 10. In other words, the first rotatable wire guiding tube 10 is aligned with the second rotatable wire guiding tube 20 and forms a continuous tube for transporting the wire 2 from the first tube 10 into the second tube 20.

(23) Like the first rotatable wire guiding tube 10, the second rotatable wire guiding tube 20 is preferably a hollow tube suitable for receiving the leading wire end 3a of the wire 2.

(24) Said second tube 20 therefore comprises said wire entrance 21a on one end and a wire exit 21b on the other end.

(25) The second rotatable wire guiding tube 20 is rotatable, preferably in the horizontal plane, around its wire exit 21b whereby its wire entrance 21a is movable from a first wire entrance position coinciding with the longitudinal feeding axis X to a second wire entrance position spaced away from the longitudinal feeding axis X and vice-versa.

(26) Before the second rotatable wire guiding tube 20 is rotated from the first wire entrance position to the second wire entrance position, the leading end 3a of the wire 2 is guided through the second tube 20 up to the desired rear end 3b is located at the wire entrance 21a of the second tube 20. This can be seen in FIG. 2a, where the leading end 3a is now crimped and has exited the wire exit 21b of the second tube 20.

(27) As the wire 2 is a continuous wire 2, the wire 2 needs to be cut such that the rear end 3b of the wire 2 (being a first wire) is defined and at the same time a leading end of a subsequent second wire is defined.

(28) For this purpose, a wire cutter 36 is configured to cut the wire 2 between the wire exit 11b from the first rotatable wire guiding tube 10 and the wire entrance 21a from the second rotatable wire guiding tube 20 when said wire exit 11b and wire entrance 21a are respectively in the first wire exit position and the first wire entrance position. In other words, the wire cutter 36 is placed adjacent the wire exit 11b of the first tube 10 and the wire entrance 21a of the second tube 20 in the position where the first tube 10 and the second tube 20 form the continuous tube, as can be seen in FIG. 2a. The wire 2 is cut by the wire cutter 36 in a cut wire 22.

(29) Now that the rear end 3b of the cut wire 22 coincides with the wire entrance 21a of the second tube 20, the rear end 3b of the cut wire 22 can be moved to a second crimping press 25 by rotating the second tube 20.

(30) FIG. 2b discloses the second wire entrance position wherein the wire entrance 21a of the second tube 20 is adjacent the second crimping press 25. Now, the rear end 3b of the cut wire 22 is ready to be crimped.

(31) The second crimping press 25 is therefore suitable for receiving the rear wire end 3b from the cut wire 2 when the wire entrance 21a of the second tube 20 is in the second wire entrance position. The second crimping press 25 is spaced away from the longitudinal feeding axis X and configured to crimp the rear wire end 3b.

(32) After crimping the rear wire end 3b, the cut wire 22 is transported out of the second tube 20 and out of the interior space A of the wire cutting apparatus 1 as can be seen in FIG. 2c.

(33) FIG. 2c discloses the cut wire 22 being cut and crimped and ready to be used in a subsequent process, e.g. for forming a wire harness in an automotive application.

(34) Very advantageous is that during the whole process, the first crimping press 15 and the second crimping press 25 are both located between the longitudinal feeding axis X and the first side wall 4.

(35) This allows an operator O to service the first crimping press 15 and second crimping press 25 in a reduced service time as said crimping presses 15, 25 are adjacent the same first side wall 4. For the operator O it is not necessary anymore to walk from the first side wall 4 to the opposite second side wall 5 to service one of the crimping presses 15, 25.

(36) A further advantage is provided during supervising or monitoring the wire cutter apparatus 1 when it is in operation. Having both crimping presses 15, 25 facing a same side allow the operator O to see both crimping presses without having to move.

(37) As can be seen particularly in FIGS. 1b and 2b, the first rotatable wire guiding tube 10 is configured to move its wire exit 11b outwards from the longitudinal feeding axis X towards the first side wall 4 and the second rotatable wire guiding tube 20 is configured to move its wire entrance 21a outwards from the longitudinal feeding axis X towards the first side wall 4. In other words, the outward movement is away from the longitudinal feeding axis towards respectively the first and second crimping presses 15, 25 and the first side wall 4.

(38) Preferably, if the wire crimping presses 15, 25 are entirely enclosed by the side walls 4, 5, 6, 9, the first side wall 4 comprises transparent areas. This allows an operator 4 to see the wire crimping presses 15, 25 from the exterior area B.

(39) Alternatively, one or more of the wire crimping presses 15, 25 are partly in the interior area A and traverse partly into the exterior area B through a crimping press opening in the first side wall 4. So, at least one of the first and second cutting presses 15, 25 is at least partially arranged in the exterior space B traversing the first side wall 4 through the crimping press opening.

(40) This has as advantage that it is even easier to service or supervise said crimping press 15, 25 by the operator O.

(41) Preferably, as can be seen in FIGS. 1a, 1b, 1c, 2a, 2b and 2c the first and the second rotatable wire guiding tubes 10, 20, 70, 80 rotate in a horizontal plane and wherein the side walls 4, 5, 6, 9 are in a vertical plane.

(42) The horizontal plane spanned by the transverse axis Y and the longitudinal feeding axis X can be seen in the top view of FIGS. 1a, 1b, 1c, 2a, 2b and 2c. A vertical axis Z is orthogonal with respect to the transverse axis Y and the longitudinal feeding axis X. Thus the vertically arranged first, second, third and fourth side walls 4, 5, 6, 9 form a rectangular shape in this top view.

(43) The side walls 4, 5, 6, 9 are all parallel to said vertical axis Z which points perpendicularly out of the top view of FIG. 1a.

(44) Furthermore, the wire cutter apparatus 1 comprises a wire exit opening 37 provided in the fourth side wall 9 for dispensing the wire 2 after cutting to the exterior space B.

(45) The wire cutter apparatus 1 further comprises a wire puller 33, arranged at an exterior side of the fourth side wall 9, for pulling and transporting the wire 2 through the second wire guiding tube 20 and into the exterior space B.

(46) Also shown, is that the wire cutter apparatus 1 further comprises a wire feeder 32, arranged at the exterior side of the third side wall 6, for feeding and transporting the wire 2 into and through the first wire guiding tube 10. In order for the wire 2 to enter the interior space A, the third side wall 6 comprises the wire feeding opening 7.

(47) FIGS. 3a and 3b show a wire cutter apparatus 100 according to a second embodiment. The wire cutter apparatus 100 has similar features as the wire cutter apparatus 1 according to the first embodiment, however the length of the second wire guiding tube 80 is different and by that also the location of the second crimping press 25. All other features may be identical and therefore the same reference numbers used in the second embodiment denote similar features as in the first embodiment.

(48) In other words, the wire cutter apparatus 100 according to the second embodiment comprises a second rotatable wire guiding tube 80 that is shorter than the length of the first rotatable wire guiding tube 10. Or inversely, the first tube 10 is longer than the second tube 80.

(49) Therefore, the first crimping press 15 is spaced away further from the longitudinal feeding axis X than that the second crimping press 25 is spaced away from the longitudinal feeding axis X. Or in other words, the second crimping press 25 is closer to the longitudinal feeding axis X than the first crimping press 15.

(50) Although, the second rotatable wire guiding tube 80 is shorter than the first rotatable wire guiding tube 10, the wire cutter apparatus 200 works similarly as the wire cutter apparatus 200 according to the first embodiment.

(51) To show the difference, FIG. 3a shows the wire entrance 81a of the second rotatable wire guiding tube 80 in the first wire entrance position and FIG. 3b shows the wire entrance 81a of the second rotatable wire guiding tube 80 in the second wire entrance position.

(52) As the second crimping press 25 is now arranged closer to the longitudinal feeding axis X than the first crimping press 15 it may now be easier for the operator to simultaneously supervise both crimping presses 15, 25 as the second crimping press 25 does not block the view of the first crimping press 15.

(53) Preferably, the fourth side wall 9 comprises a transparent area allowing the operator to simultaneously supervise the first and second crimping press when he looks in a direction parallel to the longitudinal feeding axis X.

(54) FIGS. 4a and 4b show a wire cutter apparatus 300 according to a third embodiment of the invention. Again, identical reference numbers denote similar features as in the previous embodiments.

(55) The wire cutter apparatus 300 works similar as the previous embodiments; however both rotatable tubes now comprise a kink or in other words have two rectilinear elements that are angled with respect to each other seen in the horizontal plane.

(56) FIG. 4a and FIG. 4b show a first rotatable guiding tube 40 comprising a first tube element 44 and a second tube element 45. Both tube elements 44, 45 are hollow to receive the wire 2. The first tube element 44 is angled with respect to the second tube element 45 seen in the horizontal plane. Therefore a kink 43 is formed in the first rotatable wire guiding tube 40.

(57) Also shown is that a second rotatable guiding tube 50 comprises a kink 53 between a first tube element 54 and a second tube element 55.

(58) To show the difference, FIG. 4a shows the wire exit 41b of the first rotatable guiding tube 40 and the wire entrance 51a of the second rotatable guiding tube 50 in respectively the first wire exit position and the first wire entrance position. Or in other words, the wire exit 41b and the wire entrance 51 coincide with longitudinal feeding axis.

(59) FIG. 4b shows the wire exit 41b of the first rotatable guiding tube 40 and the wire entrance 51a of the second rotatable guiding tube 50 in respectively the second wire exit position and the second wire entrance position. In other words, the wire exit 41b and the wire entrance 51 are near or adjacent respectively the first crimping press 15 and the second crimping press 25.

(60) The advantage of having rotatable wire guiding tubes 40, 50 with a kink 43, 53 is that the first and second crimping press 15, 25 may be arranged closer to each other seen in longitudinal direction.

(61) This has as advantage than operator can more easily service the first crimping press and the second crimping press as they are closer to each other.

(62) Alternatively, not shown in the figures, the first crimping presses 15 may be arranged further away from the second crimping press 25 seen in the longitudinal direction when the kinks in tubes 40, 50 are inversed.

(63) FIGS. 5a and 5b show a wire cutter apparatus 400 according to a fourth embodiment of the invention.

(64) This wire cutter apparatus 400 works similar as the wire cutter apparatuses in the previous embodiments, however now both rotatable wire guiding tubes comprise a kink and one of them is larger than the other.

(65) This has as advantage that the first crimping press 15 may be placed close to the second crimping press 25 and they can be offset with respect to each other in the lateral direction. By that, it combines the advantages of the wire cutter apparatus according to the second and the third embodiment.

(66) As can be seen FIGS. 5a and 5b similar reference numbers denote similar features of the previous embodiments. Here, the first rotatable wire guiding tube 40 is similar as that in the third embodiment, namely a first tube 40 comprising a kink 43 and a first tube element 44 and a second tube element 45.

(67) The difference is now that the second rotatable wire guiding tube 70 comprises a kink 73 between a first tube element 74 and a second tube element 75. A total length of the first tube element 74 and the second tube element 75 of the second rotatable wire guiding tube 70 is smaller than the total length of the first tube element 44 and the second tube element 55 of the first rotatable wire guiding tube 40.

(68) The effect can be seen in FIG. 5b, where both the first and the second rotatable wire guiding tube 40, 70 are shown in respectively the second wire exit position and the second wire entrance position.

(69) In this position, the wire exit 41b of the first rotatable wire guiding tube 40 is adjacent the first crimping press 15 and the wire entrance 71a of the second rotatable wire guiding tube 70 is adjacent the second crimping press 25.

(70) This way respectively the leading end 3a and the rear end 3b of the wire 2 can be crimped.

(71) Finally, FIG. 7 shows a fifth embodiment of a wire cutting apparatus 500 according to the invention being the middle wire cutting apparatus 500 in between a wire cutting apparatus 1 a mirrored wire cutting apparatus 600 according to the first embodiment.

(72) The wire cutting apparatus 500 according to the fifth embodiment comprises a third wire crimping press 535 and a fourth wire crimping press 545 as well as a third rotatable wire guiding tube 530 and a fourth rotatable wire guiding tube 540.

(73) A wire divider 34 is provided for continuously dividing a wire 2 into a first wire 42a and a second wire 42b.

(74) The first wire 42a is fed to the first rotatable wire guiding tube 10 and is processes as in one of the previous embodiments.

(75) The second wire 42b is fed to the third rotatable wire guiding tube 530. The third rotatable wire guiding tube 530 is suitable for receiving the leading end of the second wire 42b. The third tube 530 has a wire entrance 531a and a wire exit 531b and is rotatable around the wire entrance 531a whereby the wire exit 531b is movable from a first wire exit position coinciding with the longitudinal feeding axis X2 of the second wire to a second wire exit position spaced away from the longitudinal feeding axis X2 of the second wire and vice-versa.

(76) The third crimping press 535 is suitable for receiving the leading end of the second wire 42b when the wire exit of the third rotatable wire guiding tube 530 is in the second wire exit position. The third crimping press 535 is spaced away from the longitudinal feeding axis X2 of the second wire 42b.

(77) Note, that as there are two wires 42a, 42b being cut and crimped simultaneously, there are also two longitudinal feeding axes X1, X2. The first longitudinal feeding axis X1 corresponds to the first wire 42a. The second longitudinal feeding axis X2 corresponds to the second wire 42b.

(78) The third crimping press 535 is configured to crimp the leading end of the second wire 42b.

(79) The wire cutting apparatus 500 according to the fifth embodiment also comprises a fourth rotatable wire guiding tube 540 for receiving the leading wire end of the second wire. The fourth tube 540 has a wire entrance 541a and a wire exit 541b and is rotatable around its wire exit 541b whereby its wire entrance 541a is movable from a first wire entrance position coinciding with the longitudinal feeding axis X2 of the second wire 42b to a second wire entrance position spaced away from the longitudinal feeding axis X2 of the second wire and vice-versa.

(80) The third rotatable wire guiding tube 530 and the third crimping press 535 are mirrored versions of the first rotatable wire guiding tube 10 and the first crimping press 15. Here, with mirrored is meant mirrored with respect to the longitudinal axis defined by the wire 2 before it is split into a first wire 42a and second wire 42b.

(81) The fourth rotatable wire guiding tube 540 and a fourth crimping press 545 are similarly mirrored versions of the second rotatable wire guiding tube 20 and the second crimping press 25.

(82) A second wire cutter 38 is configured to cut the second wire 42b between the wire exit 531b of the third rotatable wire guiding tube 530 and the wire entrance 41a of the fourth rotatable wire guiding tube 540 when said wire exit 531b and said wire entrance 541a are respectively in the first wire exit position and the first wire entrance position.

(83) The fourth crimping press 545 is placed such that it is suitable for receiving a rear wire end from the second wire 42b when the wire entrance 541a of the fourth tube 540 is in the second wire entrance position. The fourth press 545 is therefore spaced away from the longitudinal feeding axis X2 of the second wire 42b. The fourth crimping press 545 is configured to crimp the rear wire end of the second wire.

(84) As the third and the fourth crimping press 535, 545 are mirrored versions of the first and the second crimping press 10, 20, the third crimping press 535 and the fourth crimping press 545 are both at least partially located between the longitudinal feeding axis X2 of the second wire 42b and the second side wall 5.

(85) Preferably, the wire cutter apparatus 500 according to the fifth embodiment further comprises a second wire exit opening 39 provided in the fourth side wall for dispensing a cut and crimped second wire to the exterior space B.

(86) Above, five embodiments of wire cutter apparatuses 1, 200, 300, 400, 500 have been described which all have the advantage that its first and second crimping presses are faced towards the same side wall.

(87) This allows a mirroring or multiplication of wire cutter apparatuses forming a wire cutter assembly in which the wire cutter assembly may still be operator by only one operator.

(88) FIGS. 6a and 6b show a wire cutter assembly 1000 according to a first embodiment.

(89) The wire cutter assembly 1000 comprises a first wire cutter apparatus 1, being similar to the wire cutter apparatus 1 according to the first embodiment.

(90) The wire cutter assembly 1000 further comprises a second wire cutter apparatus 600 according to a sixth embodiment which is a mirror version of the first wire cutter apparatus 1.

(91) On the left side the first wire cutter apparatus 1 is placed and on the right side the second wire cutter apparatus 600 is placed.

(92) Between the first wire cutter apparatus 1 and the second wire cutter apparatus 600 an operator space S is disposed. The operator space S is typically suitable for an operator O to supervise all presses of all wire cutter apparatuses simultaneously.

(93) Therefore, the first and second presses 15, 25 of the first wire cutter apparatus 1 and the first and second presses 615, 625 of the second wire cutter apparatus 600 all face the operator space S.

(94) FIG. 7 shows a wire cutter assembly 1000 according to a second embodiment. Here, the wire cutter assembly 2000 comprises three wire cutter apparatuses 1, 500, 600. A left side a wire cutter apparatus 1 according to the first embodiments is shown. In the middle, a wire cutter apparatus 500 according to the fifth embodiment is shown. At the right side, a wire cutter apparatus 600 according to the sixth embodiment is shown.

(95) In between the first side wall of the wire cutter apparatus 1 according to the first embodiment and the second side wall of the wire cutter apparatus 500 according to the fifth embodiment a first operator space S1 is disposed.
