    The invention relates to a transfer unit for seals or comparable cable fitting components for a cable processing system, according to the preamble of claim 1, and a method for fitting a cable with seals or comparable cable fitting components, according to the preamble of claim 7.
    Transfer units for, for example, seals or cable sleeves typically have at least one receiving mandrel which is designed for receiving the seals from a conveyor and transferring them to a seal assembly device in time with the seal processing. Such a transfer unit is disclosed, for example, in EP 1022821 A1. As can be seen in more detail in EP 881720 A2, one end of the receiving mandrel can be provided with a support sleeve or shaped in a corresponding manner, which serves to support the seal when it is pushed onto the mandrel and in which support sleeve a mounting tube for the seal after piercing the Seals can immerse.
    In these usual transfer units, a seal, that is, a flexible cable sleeve, is picked from a conveyor rail by means of a transfer mandrel and then transferred to a mounting tube. The arbor dips into the assembly tube, whereby the seal is pushed over the assembly tube. The support sleeve of the mandrel forms an end stop for the seal. The support sleeve made of metal is provided with a countersink on the front side, which is drilled so large and deep that the mounting tube fits into the sleeve with a defined clearance and can dip into it. The rest of the sleeve serves as a support to push the seal securely onto the mounting tube.
    [0004] WO 2013/046075 A1 discloses a transfer unit for seals, comprising a receiving mandrel which is designed for receiving the seals from a conveying device and transferring them to a seal fitting device. In the course of a forward movement, the mandrel picks up the seal by penetrating the central tunnel of the seal. Furthermore, the receiving mandrel has a metallic support sleeve with an end-face groove that surrounds the mandrel in a ring-shaped manner for supporting the seals. A mounting tube for the seal can plunge into the groove after piercing the central tunnel of the seal, with the tip of the receiving mandrel simultaneously penetrating the mounting tube.
    This system has proven itself for years and is very reliable, but it can especially with very small, soft, thin-walled, greatly expanded seals or seals with other special properties, as well as with certain dimensions of the mandrels and mounting pipes due to the critical gap between the outside diameter of the arbor and the inside diameter of the support sleeve can damage the seals. These injuries occur when the seal is jammed between the mounting tube and the countersink in the metal support sleeve.
    It was therefore the object of the present invention to design a transfer unit and a method for equipping a cable with seals in such a way that injuries to the seals can be reliably avoided in all material and dimensional relationships.
    To solve this problem, the transfer unit and the method are characterized by the features of the independent claims 1 and 7. Further advantageous embodiments are set out in the drawings and in the dependent claims.
    In particular, the transfer unit is characterized in that the support sleeve is made of elastic material and has a flat end face facing the seal. The material of the support sleeve is made from a much more elastic material than the material from which the mounting tube and the receiving mandrel are made. As a result, the critical air gap at which a crushing or other injury to the seal when the mounting pipe enters under the support sleeve can be significantly reduced, since the mounting pipe can expand the elastic support sleeve itself and create space for penetration under the support sleeve. In the rest of the area, the seal can be supported on the support sleeve over its entire surface.
    It is also preferably provided that the support sleeve surrounds the receiving mandrel without play. This completely avoids a critical air gap and prevents the seal from being crushed. Any annular gap for the installation tube to penetrate under the support sleeve is only formed when the installation tube itself penetrates, with the elastic support sleeve expanding.
    Another feature is that the height of the support sleeve in the direction of the receiving mandrel is at least equal, preferably greater than its diameter. This feature ensures a simple and easy widening of the support sleeve in the radial direction with good stability and support for the seals parallel to the axis of the receiving mandrel.
    It is also preferably provided that the support sleeve is made from a material with a Shore A hardness in the range between 60 and 120. Particularly preferred is an embodiment in which the support sleeve is made from a material with a Shore A hardness of 90 +/- 5.
    To select the support sleeve depending on the application and to be able to adapt the transfer unit, or to be able to easily replace worn support sleeves, a preferred embodiment of the invention is characterized in that the support sleeve is held on the receiving mandrel by means of a releasable connection. This connection can in particular also be brought about solely by the static friction of the elastic support sleeve with the receiving mandrel. If it is to be replaced, it is simply pulled off and a new support sleeve is attached to the receiving mandrel. Since the inside diameter of the support sleeve is typically smaller than the outside diameter of the receiving mandrel at the point provided for the support sleeve, it is held there by static friction.
    The object defined at the outset is also achieved by a method for equipping a cable with seals, which is based on a promotion of the seals by a conveyor device in a receiving position provided for receiving by a transfer unit. There the seals are picked up by the conveying device as part of a forward stroke of a receiving mandrel by inserting this receiving mandrel into the preferably central tunnel of the seal, after which the receiving mandrel is immersed in an assembly tube. The seal is pushed over the mounting tube. The seals are then installed on a cable to be processed.
    To achieve the object, this method is characterized according to the invention in that the seals are received in a transfer unit, which is designed according to one of the preceding paragraphs and wherein the seals are attached to a support sleeve made of elastic material and with a plane facing the seal Support the face.
    Preferably, this method is further characterized in that the mounting tube in the course of the relative movement towards the receiving mandrel lifts the support sleeve from the receiving mandrel, expands it and then slides in between the receiving mandrel and the support sleeve.
    Another advantageous variant of the method is characterized in that the mounting tube is withdrawn in the course of the relative movement away from the receiving mandrel from the space between the support sleeve and the receiving mandrel, after which the support sleeve is again around the receiving mandrel without play.
    [0017] Further advantages, features and details emerge from the following description, in which exemplary embodiments are described with reference to the drawings. The features mentioned in the claims and in the description can each be essential individually or in any combination.
    [0018] The list of reference symbols is part of the disclosure. The figures are described in a coherent and comprehensive manner. The same reference symbols denote the same components, reference symbols with different indices indicate functionally identical or similar components.
    The figures show: FIG. 1 a schematic representation of the sequence of equipping cables with seals, FIG. 2 an enlarged representation of a receiving mandrel with a picked seal, FIG. 3 the position of the receiving mandrel shortly before the piercing of the sea expansion jaws, FIG. 4 the receiving mandrel partially immersed in the mounting tube with a seal already pushed up against the support sleeve, with open sea expansion jaws, FIG. 5 the receiving mandrel with the mounting pipe inserted under the support sleeve and seal on the mounting pipe, FIG. 6 a sectional view of a receiving mandrel with conventional rigid support sleeve and a representation of the input area of the support sleeve on an enlarged scale, and FIG. 7 a sectional view of a receiving mandrel with support sleeve and a representation of the input area of the support sleeve on an enlarged scale.
    Fig. 1 shows from left to right schematically the process of equipping cables K with seals 1. The seal 1, ie a flexible cable grommet, or another cable assembly component is picked by means of the mandrel 2 from a conveyor rail 3 and then in a Transferred two-stage vertical movement to a mounting tube 4. The receiving mandrel 2 performs a two-stage vertical movement.
    In the first stage, the receiving mandrel 2 penetrates the so-called sea expansion jaws 5 in the state shown in FIG. 2, as indicated in FIG. 3 by the downward arrow. These jaws 5 are equipped with elastic inserts which are provided with a hole in the center. While the receiving mandrel 2 moves through the sea expansion jaws 5, the seal 1 located on the receiving mandrel 2 is pushed against the support sleeve 6. Shortly before the seal 1 has reached the end face 6b of the support sleeve 6, the sea expansion jaws 5 are opened, for example by means of cam control, so that the seal 1 is no longer pushed on or compressed. This position is shown in FIG. 4, in which the sea expansion jaws 5 are already open. It can also be seen that the tip of the receiving mandrel 2 is already immersed in the mounting tube 4 during or shortly thereafter. The seal 1 is pushed onto the tube 4 by further movement of the receiving mandrel 2 and the mounting tube 4 towards one another. This position is shown in FIG. The mounting tube 4 dips into the depression 6a of the support sleeve 6, the seal potentially being damaged by crushing or shearing between the mounting tube 4 and the support sleeve 6.
    Fig. 6 shows the relationships in conventional support sleeves 6 made of metal, with an annular recess 6a at the front end. This depression 6a is drilled out so large and deep that the mounting tube 4 fits into the sleeve 6 with a defined clearance and can dip into it. The mounting tube 4 finally protrudes approx. 0.5-1.5 mm beyond the end of the seal 1 facing the support sleeve and protrudes under the support sleeve 6. The remaining part of the end face 6b of the support sleeve 6 serves as a support in order to push the seal 1 securely onto the mounting tube 4.
    7, on the other hand, shows the conditions for the support sleeve 6 made of elastic material, which preferably lies around the receiving mandrel 2 completely without play. This support sleeve 6 is made of a material which is more elastic than that of the mounting tube 4 and preferably also than the material from which the receiving mandrel 2 is made. The material of the support sleeve 6 preferably has a Shore A hardness in the range between 60 and 120, preferably a Shore A hardness of 90 +/- 5.
    Especially in the case of very small, soft, thin-walled, greatly expanded seals or seals with other special properties, an injury to the seal 1 by avoiding the jamming of the seal 1 between the mounting tube and the - now no longer necessary - lowering 6a in the end face 6b of the support sleeve 6 can be avoided. There is no air gap between the support sleeve 6 and the outside of the receiving mandrel 6, but rather the flexible support sleeve 6 closes around the receiving mandrel 2 like a rod seal. It is only widened radially by the mounting tube 4 itself, made possible by its elasticity, when it dips into the mounting tube 4. There is no significant compression in the axial direction, as there is no significant load in this direction when the seal is pushed.
    During this process, the seal 1 can no longer get between the tube 4 and the receiving mandrel 2, but is pushed axially onto the mounting tube 4 by the flexible support sleeve 6 without causing any crushing, shearing or other damage to the seal 1 .
