Description

The invention relates to a transport unit for a stopper for crimping cable lugs with a cable end. Furthermore, the invention is based on a stopper machine with such a transport unit.

With the stopper usually a stripped cable end of an electrical conductor, such as a stranded wire, provided with a wire end sleeve for protection to connect the cable end without damage in particular to terminals. Furthermore, it is known with the stopper to provide a stripped cable end with a cable lug to fix the cable end in a simple manner via a screw or plug connection. For screw connection of the cable lug is designed with an eyelet / ring or a fork. In contrast, the cable lug for plug connection, which is often provided in the automotive industry, designed as a flat plug.

It has been shown that the wire end ferrules can be fed by their usually rotationally symmetrical configuration relatively easily to a crimping tool of the stopper machine. A handling of the cable lugs is much more difficult due to their complex geometry, which is why an isolated feeder device is expensive. For example, an impact machine with a transport unit in the DE 44 40 835 , of the DE 93 08 266 or the DE 197 37 148 disclosed. These stop machines have in common that the ferrules or the cable lugs are arranged on a webbing and are fed via this the stopper machine. Such an arrangement on a webbing is device-technically complex and expensive, but the cable lugs are thus easy to handle.

In contrast, the invention has for its object to provide a transport unit for a stopper, which is simple in design and leads to a cost-effective operation of the stopper. Another object of the invention is to provide a stopper machine which is simple in terms of device design and is inexpensive to use.

The object with regard to the transport unit is achieved according to the features of claim 1 and with regard to the stopper machine according to the features of claim 8.

Other advantageous developments of the invention are the subject of further subclaims.

According to the invention, a transport unit for a stopper for crimping cable lugs, is provided with a cable end. The transport unit advantageously has a vibratory conveyor in which the cable lugs can be introduced as bulk material. The vibratory conveyor is in this case designed such that the cable lugs are occasionally fed to a feed tube of the transport unit. In turn, the cable lugs can then be conveyed to the crimping tool via the feed tube.

It has surprisingly been found that the cable lugs despite their comparatively complex geometry by a suitably designed vibratory conveyor can be singled. On the known from the prior art straps that are previously used in the handling of cable lugs, can thus be advantageously dispensed with, which significantly minimizes the device complexity and cost.

Preferably, the vibratory conveyor has an approximately funnel-shaped feed pot, which tapers in the direction of gravity, so that the cable lugs are easily introduced as bulk material.

To promote the cable lugs, the feed pot may have an approximately frusto-conical or conical inner wall. Along this, a ramp-shaped feed path can extend in a helical or cyclonic manner. The cable lugs are then conveyed in an ascending direction of the feed path by vibratory excitation of the Zuführungsopfs.

The cable lugs may only be introduced into the feed pipe in a certain orientation, which is why a device for the removal of the device is simply provided on the feed pot. This is designed so that misaligned cable lugs are guided away from the feed path and fall back into the feeder bowl. The rejection element is preferably provided in the end region of the feed path. The incorrectly oriented cable lugs are preferably cable lugs with their ring or fork pointing away from the inner wall. Alternatively or additionally it can be provided with the rejection element to sort out superimposed and / or wedged cable lugs.

The deflector element and the feed track can delimit a preferably slot-shaped feed space, in which cable lugs can be carried out individually with their ring or fork.

Advantageously, the rejection element has a deflecting surface which, starting from the inner wall, extends over the feed path, in particular along a curve, and is configured in the shape of a ramp is. As a result, overlapping cable lugs can be singled out and cable lugs, which point away from the inner wall with their ring or fork, are sorted out.

In a further embodiment of the invention, a second rejection element can be provided, which, as seen in the conveying direction, is preferably arranged directly after the first deflecting element.

The second rejection element can be configured in such a way that misaligned cable lugs, in particular cable lugs, which are oriented wrongly about their longitudinal axis (ie are twisted by about 180 ° about their longitudinal axis) can be sorted out.

The second rejection element may have a guide slot which extends in the conveying direction, in particular along a curve, wherein in the guide slot in the cable lugs with their ring or fork are submersible. The guide slot may be inclined so that the guided therein and properly oriented cable lugs do not fall back into the feeder bowl or are guided safely. In this case, the guide slot can be seen in the radial direction and in a direction away from the Zuführungsopf tilt down.

Preferably, a pocket is provided in the second deflector element, which is introduced into the feed path of the second deflector element and into which the wrongly oriented cable lugs (preferably those which are rotated through 180 ° about their longitudinal axis) are at least partially submersed with their sleeve portion, wherein a pocket wall the bag, the misaligned cable lugs for sorting away from the guideway are movable. The bag can then be open inwards so that the cable lugs can fall out of the bag.

When viewed in the conveying direction, the guide track can be slightly lowered after the pocket, which leads to improved guidance of the correctly oriented cable lugs.

An end piece at the top end of the feed path connects it to a feed tube to insert the lugs from the feed path into the feed tube.

The end piece may have a free space, which adjoins the guide slot of the second deflection element and may be configured such that the ring or the fork of the cable shoe is exposed therein and can be pivoted in the direction of gravity. The cable lug can then be supported on its sleeve section with an annular or fork-side end face on a guide surface of the end piece and guided to the feed tube.

The guide surface of the end piece and the guide track are preferably spaced apart, whereby a pivoting of the cable lug is made possible and this is moved with its sleeve portion of the guide track to the guide surface. The guide surface of the tail is in particular ramp-shaped.

To the free space of the tail can be followed by a guide slot in the conveying direction over which the cable lug, in particular standing (longitudinal axis of the cable lug extends approximately vertically) is guided laterally and is supported on the guide surface of the tail over its sleeve portion.

The guide of the cable lug in the tail can be made around a curved path which extends away from the feed pot to guide the cable lug to the feed tube, which may be arranged adjacent to the feed.

The feed tube preferably extends approximately vertically, wherein the cable lugs are introduced via the tail in an upper opening in the feed tube.

Advantageously, the feed tube is designed such that it can be used for different types of cable lugs. Thus, it is not necessary to use a correspondingly adapted feed pipe for different cable lugs.

Preferably, after the feed pipe, a transfer device (separating device) is provided in order to feed lugs separated from the feed pipe to the tool. The transfer device can in this case be actuated by a cylinder.

The transfer device can be movable approximately in the vertical direction between the feed tube and the tool with a certain stroke in order to transport at least one cable lug from the feed tube to the tool.

Furthermore, the transfer device can have a continuous guide opening which extends approximately in the vertical direction, into which a cable lug can be introduced from the supply pipe and can be carried out to the tool.

Preferably, a separating element is provided, via which the guide opening can be opened and closed. This can be guided in a guide recess of the transfer device. The separating element is preferably by the movement of the transfer device towards the tool from a certain stroke, the guide hole free and closes in the opposite direction from a certain stroke the guide hole. The guide recess may be configured such that different cable lugs are feasible.

The separating element can in turn be actuated via an actuating element which is mounted in the transfer device and which projects away from the transfer device in the direction of movement and approximately parallel to the guide recess towards the tool and with a movement of the transfer device towards the tool from a certain stroke on at unzartigtem separating element the tool is supported and immersed in the transfer device for actuating the separating element. The immersion of the actuating element can take place counter to a spring force of a spring.
