DESCRIPTION

Variable feeding device for a crimping group Technical field

The present invention relates to a feeding device for a crimping group. With such a crimping group, identical crimping geometries, eg socket or plug contacts, can be crimped with a cable.

State of the art

The prior art EP 1 898 502 A2 is known. This document refers to a crimping device with an interchangeable module only as a closed construction group, which contains a crimping group and at least one storage unit for the crimping contact elements on a common base plate. The base plate has a tool holder for the crimping group and a storage support for the storage unit, being able to join in a nigid way during the use to which the tool holder is intended with the crimping device, and from which the Storage support can be decoupled according to the oscillation technique.

As an additional state of the art, an automatic crimping system of EP 2 169 783 A1 should be mentioned. This automatic crimping system comprises a crimping group driven by a first motor and a reserve roller on which a band of metal contact elements and a separating strip deposited thereon are wound together forming a spiral. A folding device is associated to the crimping group to fold the band of contact elements in the crimping group. To remove the band of contact elements from the reserve roller, a second motor driven by signals and a sensor, sensor that drives the second motor, are provided such that the band of contact elements in the intermediate zone between the reserve roller and the crimping group is free of tensile stresses.

In the case of an automatic crimping system described in EP 2 169 783 A1 the sensor is a closing contact for a control voltage, the closing contact comprising at least one input that is arranged in the deepest place of a storage in suspension and can be formed by a metallic deposit.

Document DE 20 2010 017 139 U1 shows a crimping machine for different crimping and crimping processes, in particular cable making. In one embodiment, a separate deposit frame is shown that serves to support integrated tool units.

In addition, documents EP 0 889 561 A1 and EP 0 889 560 A1 which relate to crimping devices are known. In order to enable any alternation during the feeding of different types of contact to a crimping device, the crimping device has several crimping tools that can be joined together to the sides and have different crimping inserts, arranged on the sides next to each other. others.

US 5,327,644 A1 shows a cable equipment device.

US 4,982,830 A1 shows a feeding device for a cable manufacturing machine. This comprises two carousel devices with which individual plugs are transported.

The crimping devices according to the state of the art are configured to process the same crimping geometry without exchanging a crimping group, that is, for example, the crimping geometry of a socket or plug, given that the crimping group itself It is configured only for crimp treatment. With such a device it is possible to crimp with wires in a production cycle or the bushes fed on one strip or the plugs fed on another strip. However, if the production process has to be changed from socket to plug, so the reserve roller must be exchanged with the band of contact elements that have the bushings / plugs.

Object of the invention

Against the background of the state of the known art, it is the objective of the present invention to provide a feeding device for a crimping tool that can be used more variably and in which a flexible equipment process can be carried out.

A central idea of the present invention is to facilitate in a feeding device several feeding pianos. In each of the preferably two feeding planes a band of contact elements is fed to a common crimping group. The mentioned power planes can be modified in their position in such a way that it can be changed between the bands of contact elements provided, and therefore the band of contact elements needed in each case can be introduced into a crimp group with a tool without having than replace the reserve roller.

According to the invention, a feeding device for a crimping group is provided. A crimping group of this type has a base body and a tool installed therein with which a crimping of a contact element fed by a band of contact elements with a cable can be made. Such a tool that is commonly used for the bands of fed contact elements may have a mobile crimping tool with punching hole, insulating crimping and wire crimping, as well as immovable elements facing this mobile crimping tool, In particular, it is made up of blades, blades, anvil and contact supports.

The feeding device according to the invention presents in this case: a first carriage that can move in a first direction and a second carriage that can move in a second direction fundamentally perpendicular to the first direction, as well as a first delivery mechanism and a second delivery mechanism to receive and deliver each of the bands of contact elements to the crimping group. These two delivery mechanisms are linked to the first car and the second car and can move through them.

The feeding device according to the invention has in this case the advantage that in each individual treatment cycle one of the bands of contact elements for crimping with a cable can be selected without having to change the reserve roller or without having than insert another band of contact elements in the feeding device.

In this case, the crimping group tool presents the same geometry for both bands of contact elements. With this same geometry, the first or second band of contact elements can be connected with a cable. In this respect, the bands of contact elements can be differentiated from one another, particularly in that one band of contact elements has plugs and the other band of contact elements has bushings. These usually have essentially the same crimping geometries.

By means of the mobility of the feeding device with the first mobile carriage it can be additionally guaranteed to select a band of contact elements that can be made with the second carriage, that a remainder of the other band of contact elements respectively that remains in a stage Previous work in the tool area of the crimping group does not prevent the selection caused by the second carriage. If not, it could be that a remainder of the band of contact elements used previously remains suspended in the area of the tool, and therefore it is not possible, if necessary, the selection movement with the second expensive.

By facilitating the first and second delivery mechanism, it can be ensured that a first and second band of contact elements can be fed to the crimping group. If one of the two bands of contact elements is not used, it is available despite it, and can be selected on request in a subsequent duty cycle.

In an embodiment of the feeding device according to the invention, the movement of the second carriage is limited at least in one direction through a stop or a sensor. Therefore, it is possible to take the second carriage used for the selection of the first or second band of contact elements to a defined position with which a selection of the first or second band of contact elements is fixed. In this regard, particularly the stop has the advantage that a movement of the first car is mechanically limited, and therefore usually does not require any additional adjustment. A variant of this type is also relatively robust.

According to a further embodiment, the first delivery mechanism and the second delivery mechanism are similarly configured. This simplifies the manufacture of the feeding device, since the same parts can be used for the first and second delivery mechanism. Preferably, the feeding device is equipped with a first lifting cylinder for an adjustment movement of the first car and a second lifting cylinder for an adjustment movement of the second car. Lifting cylinders of this type are available relatively cheaply and have little maintenance. The same applies to the case that the first and / or second feeding mechanism is equipped with a lifting cylinder for a movement of delivery of the band of contact elements.

In an embodiment of the feeding device according to the invention, the first and / or the second feeding mechanism has an advance element, in particular an advance finger that is preferably engaged by means of a projection in the respective contact element band . For this, the band of contact elements is provided, for example, with notches, such as holes, in which the projection of the advancing element can be engaged. In this way a movement of delivery of the band of contact elements

It can be done reliably and safely.

In addition, the first and / or the second feeding mechanism may have a GMA carriage which, for connection with an advance element holder, in particular an advance finger holder, has a hinge bolt, in which a compression spring that is in contact with the gma carriage and the advance finger holder. With this mechanism it can be ensured that an advance element provided in the advance element holder during a movement in the direction of the crimping group (delivery movement) is engaged in a band of contact elements (in particular in a notch of the band of contact elements). In the case of a recoil movement in which the band of contact elements must not move, the advance element deflects or tilts, and therefore disengages from the band of contact elements.

In addition, the first and / or the second delivery mechanism may have a brake. The brake is used to apply a certain pressure force on the band of contact elements (contact strip) so that it does not slip in an uncontrolled manner. The band of contact elements (the strip) is then damped, e.g. ex. during the advance in the movement, so that through the "impulse of advance" does not continue to slip. When removing the finger, by force it is also prevented that the strip is not mistakenly pulled back.

Also in the first and / or second delivery mechanism a conductive plate can be provided in each case with which the band of contact elements is deflected from a reserve roller. In this way the band of contact elements is conducted in a plane of the first and / or second delivery mechanism without the danger of torsion or of the contact element being caught.

It is preferably provided that the delivery device according to the invention is installed with the crimping group on a mobile carriage. In this way the feeding device unit and crimping group can be removed, and the feeding device can be more easily equipped.

Figure 3 a detailed view of Figure 2 Description of the preferred embodiments

A preferred embodiment of the present invention, as well as its possible modifications, are described in detail with reference to the accompanying drawings.

Figure 1 shows a crimping tool with which a particular crimping geometry of a socket or plug can be processed. A crimping group 1 of this type has a base body 2 in which a so-called clamping block 3 is provided. Through the clamping block 3 a carriage 4 moves in a range of the base body 2 in a vertical direction. At one end of the carriage 4 a mobile crimping tool 5 is provided which moves through a movement of the carriage 4 in a vertical direction. The crimping tool 5 has several elements, in particular a punching hole, an insulating crimper and a wire crimping tool.

On one side facing the mobile crimping tool 5, a gam of blades 6 is provided which houses a blade 7 as well as an anvil 7a. These elements form a treatment zone for crimping a socket / plug with a cable. On one side of the treatment zone an ejection 9 is provided in the form of a slide for the transport of broken pieces into pieces of the support strip. The strip is broken into pieces by the range of blades 6 and the blade 7 in each cycle.

Also in the area of the crimping group 1, a feeding device 10 is provided which can move with respect to the crimping group 1.

For this, the crimping device 10 has a carriage 11 which, as indicated in Figure 1, through the corresponding arrow, for example, through a lifting cylinder, can be raised and lowered in a vertical direction. In this respect the vertical direction of the carriage 11 in figure 1 is limited in the direction shown upwards in figure 1 by a stop 12 in which a section 11a of the carriage 11 can collide. The movement in the opposite direction is fixed by a sensor means or an additional stop means.

In addition, the feeding device 10 has a mobile carriage 13 that can be moved in a horizontal direction that is operated by a lifting cylinder 14. By means of an adjustment movement of the carriage 13, the entire feeding device 10 can be moved in a horizontal direction.

As indicated in figure 1, by means of the feeding device 10, two bands of contact elements C1 and C2 are fed towards the crimping group 1. The bands of contact elements C1 and C2 are arranged in this case in a direction Vertical in different planes.

The upper contact element band C1 is adjusted by means of a lift cylinder 20 in a horizontal direction when the lift cylinder 20 is operated. For this, the lifting cylinder 20 has at least one gma column 21 (in the present embodiment example there are two gma columns arranged in parallel with each other of which in the present figure 1 only one can be clearly seen).

Along the column-gma 21 a carriage of gma 22 can move in a horizontal direction. A brake 27 is provided that serves to bring a certain clamping force into the band of contact elements so that it does not slip in an uncontrolled manner. The band of contact elements is damped in the movement p. ex. during the advance, so that it does not continue to slide due to the "forward momentum". The carriage of gma 22 is connected through a molding spring 23 and a hinge bolt 24 with an advance finger holder 25. The advance finger holder 25 has an advance finger 26 which extends starting therefrom. a direction fundamentally perpendicular to the direction of advance. The advance finger 26 may be provided detachably in the advance finger holder 25, as in the embodiment shown, or be integrally configured with it.

The advance finger 26 rests on a gma 8a of a table 8 and slides in the case of an advance movement along the gma 8a of the table 8. The table 8 is part of the feeding device 10, and therefore it can be moved by car 11 and 13 in a vertical and horizontal direction.

In addition to the "lower" contact element band C2 shown in FIG. 1, a cylinder 30 is provided which is essentially configured similarly to the lifting cylinder 20 for the first contact element band C1. Therefore, for the delivery mechanism of the second band of contact elements C2 also a carriage of gma 32 that can move along a column-gma 31, which has a hinge bolt 34 and is connected with a ( spring not shown) with the advance finger holder 35. A brake 37 is also provided. The advance finger holder 35 has an advance finger 36 which can be engaged in the contact element band C2. As for the additional elements, reference is made to the previous description regarding the advancement mechanism of the first band of contact elements.

The entire device with the feeding device 10, crimping group 1 and additional elements can be detached from the following figures 2 and 3 in detail.

In this case the crimping group 1, as well as the feeding device 10 which is configured as a common unit, is installed on a shuttle 40. In addition, the feeding device 10 comprises two conductive plates 41 and 42 which are provided in each case for the first band of contact elements C1 and the second band of contact elements C2. The conductive plate 41 is provided for the upper contact element band C1, while the additional conductive plate 42 is provided for the lower contact element band C2.

The shuttle 40 comprises a first reserve roller 50 and a second reserve roller 60. The first reserve roller 50 is connected through a rotating shaft 51 with the shuttle 40, and has disc-shaped fasteners 52 within which a band of contact elements as well as a separating strip not shown in detail are housed as layers.

Correspondingly, the second reserve roller 60 is connected on a second axis 61 with the shuttle 40 and has two fastener elements 62 in the form of a disk.

In a preferred embodiment, the reserve rollers 50 differ in that in one of the reserve rollers a band of contact elements with bushes is housed, and in the other reserve roller a band of contact elements is housed with plugs. which can be guided through the conductive plates 41, 42 separately towards the crimping group 1.

The shuttle 40 can be accommodated by a movable carriage 200 for transport.

In order to unwind the band of contact elements provided in the reserve roller 50, a stretching roller 54 is provided in which a separation band (not shown) guided through an inverting pulley 56 is moved. In this respect by means of a movement of a motor 55, for the movement of the stretching roller 54 it is caused that a band of contact elements coming from the reserve roller 50 comes into contact with a reservoir 53 and therefore stops a movement of the motor 55. By this mechanism It provides that the band of contact elements is always provided for without the hanging labels or the sockets / plugs of the band of contact elements becoming entangled. By means of the movement of the reserve roller 50 by means of a movement of the stretching roller 54 which in turn deals with a removal of the separation band, it is ensured that no tensile load is applied on the band of contact elements.

The second reserve roller 60 is provided in a complementary manner to the reserve roller 50 and is also rotated by a movement of a stretching roller 64. The stretching roller 64 is driven by a motor 65 in such a way that a separation band it moves through an inverting pulley 66 towards the stretching roller 64 and therefore the band of contact elements provided as layers in the reserve roller 60 with the separation band leaves the reserve roller 60. The drive of the motor 65 is also controlled through a contact of the band of contact elements with a tank 63.

The movable carriage 200 can be moved with the elements described above and in the preferred embodiment, described is equipped with roller 43. Thus the carriage 200 can be brought to the area of a frame 100, frame 100 that has a protection device 101 in the form of a separation wall. In this regard the movement of the carriage 200 is particularly advantageous because the carriage 200 can move away from the frame 100 and then the reserve rollers 50, 60 are essentially freely accessible. This is credited as advantageous among others during the replacement of the reserve rollers 50, 60.

For the replacement of the reserve rollers 50, 60 it is also provided that the axis 51 and the axis 61 of the first and second reserve roller 50, 60 are oriented inclined with respect to each other. Therefore, good access to the reserve rollers 50, 60 and their axes is facilitated. This construction, however, does not cause the angular orientation of one of the axes 51, 61 to produce a torsion of the respective contact element band, and therefore a disadvantageous influence on a transport of the element band. contact in one of the conductive plates 41,43.

An operation of the feeding device 10 described in combination with the crimping group 1 can proceed as follows.

Before a crimping operation is carried out, the carriage 11 is adjusted in a vertical direction, and by the movement of the carriage 11 the upper contact element band C1 or the lower contact element band C2 is selected for a treatment. According to this selection, the carriage 13 moves in the direction of the crimping group 1, whereby the respective band of contact elements C1, C2 is brought to the area of the crimping tool 5.

Conditioned by the selection of the first or second band of contact elements C1, C2, one of the lifting cylinders 20, 30 is operated. Since in figure 1 of the present application the upper contact element band C1 was selected A forward movement of the contact element band C1 must be described in detail.

To this end, the lift cylinder 20 is driven, so that the carriage 22 is tilted outwardly along the gma column 21 in a horizontal direction. By means of this tilting movement out of the carriage 22, it comes into contact with the wire spring 23 that is connected through the hinge bolt 24 in the forward finger holder. The forward finger clip 25 with the advance finger 26 is also moved by the described tilting movement of the grinding car 22. The advancing finger 26 has in this respect a projection that engages in a groove in the band of contact elements C1 and during the horizontal outward tilt movement, drag the band of contact elements C1 in the direction of the tool 1.

During a recoil movement of the carriage 22, by means of the molding spring 23 and the hinge bolt 24, a rotation movement of the advance finger holder 25 provided with the advance finger 26 is caused, such that the projection of the advancing finger 26 comes from the notch provided in the contact element band C1, and therefore the contact element band C1 does not move with it in this direction. If the contact element band C1 is fed, by means of a movement of the crimping tool 5 a crimping is carried out between a cable end and the plug / socket fed from the contact element band C1.

For the next treatment cycle (crimped socket / plug with cable), a new selection can now be made by means of the present feeding device 10, and therefore the band of the next stage or the previous stage is selected. contact elements C1, or select the contact element band C2 by a vertical adjustment movement of the carriage 11.

If the contact element band C2 is treated, then the carriage 13 first performs an adjustment movement in a horizontal direction to guide the contact element band C1 from the treatment area. Therefore, it is ensured that a remainder of the band of contact elements C1 remaining in the area of the blade array 6 is not "bent" by a vertical adjustment movement of the carriage 11, or the band of contact elements C1 not it is suspended in the blade grid 6.

Then, through the carriage 11, the vertical adjustment movement is carried out to raise the band of contact elements C2 to the level from which it can be introduced into the treatment area of the crimping group 1.

In the above-described embodiment, the bands of contact elements C1, C2 are arranged vertically one above the other. In another embodiment, however, it may be provided that the bands of contact elements C1, C2 are arranged side by side horizontally.

In addition, the described embodiment is oriented to the treatment with two bands of contact elements C1, C2. However, it has been shown that the number of bands of contact elements is not limited to this and therefore more than two bands of contact elements can also be provided. In the case of such a modification, the carriage 11 provides a corresponding adjustment and facilitation of the respective contact element band.

Even when in the case of the crimp group described it is preferred that a tool be used for the treatment of the contact element bands C1, C2, it can also be provided in another direction that a tool change additionally takes place.

All of the described embodiments and modifications may be combined with each other within the scope of this invention and configure additional embodiments described not explicitly.
