Definitions
- the invention relates to a transport unit which can be used in an automatic crimping machine and which is used for the step-by-step transport of a belt strip with ferrules.
- the publication DE 197 37 148 A1 shows such a transport unit.
- a transport pawl is articulated on an oscillatingly driven transport slide, the pivot bearing of which oscillates with the transport slide.
- a feed nose of the transport pawl is attached to the respective ferrules so that they are pushed out individually from a channel of the transport unit.
- the feed nose has a contact area that is aligned perpendicular to the feed direction, so that during a feed movement the feed nose remains in contact with the ferrule and safely transports it in the feed direction.
- the entire belt strip is tightened.
- the other side of the feed nose is designed in such a way that when the transport slide moves back against the feed direction, it slides off the adjacent ferrule and does not pull it back.
- a transport unit for the same purpose is disclosed in the publication DE 197 14 964 C1.
- the transport pawl Apart from the transport pawl, whose swivel bearing oscillates with the transport slide (sled), it also has a ratchet that works in a basically similar way, the nose (approach) of which also dips between the individual ferrules.
- the locking pawl is articulated on the base body of the transport unit.
- the nose of the pawl has a contact area which is aligned perpendicularly to the direction of advance and which remains in contact with the wire-end ferrule in question during a retraction movement of the transport nose of the transport pawl and holds it securely.
- the entire strap strip is held.
- the other side of the nose is designed in such a way that when the Transport lug slips off the adjacent ferrule and does not hold it back.
- the pawl In the installation position shown in the figures of DE 197 14 964 C1, the pawl is arranged above the wire-end ferrules. A long arm of the pawl extends from its pivot to the ferrule to be held. The weight of this long arm is reinforced by a spring.
- the transport unit is therefore not suitable for an inverted installation position, in which the pawl should enter between the ferrules from below, since in this case the long arm of the pawl reduces the force with which the nose enters.
- the disadvantage of such transport units is that the function of the single pawl is dependent on the installation position of the transport unit.
- the invention is based on the object of creating a transport unit whose holding function is improved in different installation positions.
- the claimed transport unit has a base body in which a sleeve channel is formed, through which a belt strip with ferrules can be moved step by step in a feed direction by means of a transport lug.
- the transport lug is formed on a transport pawl, which is articulated by means of a pivot bearing to pivot on a transport slide.
- the transport slide is guided parallel to the sleeve channel and can preferably be driven in an oscillating manner by means of a coupling device (eg a pin) and a main spring.
- the transport lug is pushed with a force transverse to the feed direction and transverse to the sleeve channel between two ferrules.
- the belt strip can be supported in a retraction direction opposite to the advance direction by means of a first retaining lug.
- the first retaining lug is formed on a first retaining pawl, the first pivot bearing of which is fixed to the base body.
- the first retaining lug is also pushed with a force transverse to the feed direction and to the sleeve channel between two ferrules.
- the belt strip can also be supported in the retraction direction by means of a second retaining lug, the second retaining lug being formed on a second retaining pawl, the second pivot bearing of which is also fixed to the base body.
- the second retaining lug is also pushed with a force transverse to the feed direction and to the sleeve channel between two wire end sleeves.
- the retaining lugs of the retaining pawls have, in the manner known per se from DE 197 14 964 C1, a contact area which is aligned perpendicularly to the feed direction and which remains in contact with the affected ferrule during a retraction movement of the transport lug and holds it securely. The entire strap strip is held.
- the other side of the two retaining lugs is designed in such a way that when the transport lug moves forward, they slide off the adjacent ferrule and do not hold it back.
- the holding function is further improved in different installation positions when the two holding pawls are opposite one another with respect to the sleeve channel.
- a base-fixed stop for limiting the pivoting movement in the insertion direction is preferred for each retaining pawl, against which a respective extension of the retaining pawl can come into contact, which is formed with respect to the pivot bearing on a side of the retaining pawl opposite the retaining lug.
- the entire transport unit is made of metal.
- the force of the retaining lugs and/or the transport lug can/can simply be generated from their own weight or from the weight of a weight section of the respective pawl in terms of device technology.
- the weight portion may be the dead weight of the pawl and/or lug.
- the transport unit according to the invention is preferably installed in an automatic crimping machine in an installation position in which the ferrules are moved horizontally through the ferrule channel.
- the weight section with respect to the pivot bearing must be formed on an extension of the pawl opposite the nose. If, on the other hand, the lug is to be pushed from above between two ferrules in the preferred installation position of the transport unit, then in the case of the weight section, this must be formed with respect to the pivot bearing on the area of the pawl on which the lug is also formed.
- the pawls are inserted between the ferrules safely and independently of the preferred installation position, it is particularly preferred if at least part of the respective force is generated by means of a spring which acts on the respective pawl.
- this spring is supported on a spring system fixed to the base body, and in the case of the transport pawl, the spring is supported on the transport slide. It is particularly preferred if all three pawls each have a spring that tensions the respective nose between the ferrules.
- the two retaining latches are the same.
- they can Retaining pawls can also be designed to adapt to the existing space with different dimensions, in particular different thicknesses.
- the transport lug and the first retaining lug are pushed from above between two wire-end ferrules in each case in the preferred installation position of the transport unit, while the second holding lug is pushed from below between in each case two wire-end ferrules.
- a cover is attached to the outside of the base body and extends along or parallel to the sleeve channel.
- the second pivot bearing of the second retaining pawl is arranged in a bearing section of the cover.
- the bearing section can also form a wall section of the sleeve channel on its upper side in the preferred installation position.
- the two retaining pawls are preferably arranged between the transport pawl and an outer surface of the lid.
- At least one of the three pawls may have an extension opposite the lug relative to the respective pivot bearing.
- a pin may be secured to the extension, movable with pivotal movement of the latch, and extending outwardly through an outer surface of the cover. This allows the movement of the affected latch to be observed and, in the event of a fault, the affected latch can be moved manually without having to remove the cover.
- all three pawls have such a pin.
- the pivot bearing of the transport pawl is arranged on the transport slide.
- a recess eg a depression
- the coupling device for example a pin
- the bearing section fixed to the cover is also arranged essentially in the recess of the transport slide. The bearing section with the second retaining pawl mounted therein can then be positioned as close to the transport pawl as possible to save space during assembly of the cover.
- a separator plate is formed or attached to the transport slide to keep the ferrules at a level, e.g.
- the separating plate preferably has an extension directed in the feed direction, which is moved out and retracted in an oscillating manner in the feed direction.
- An end face of a respective ferrule can be brought into contact with the extension transversely to the feed direction when the ferrule is severed.
- a through-hole (e.g. a slot) in the separating plate can be arranged between the extension and a main portion of the separating plate, into which a separating knife for separating a ferrule from the belt strip can be inserted.
- the main section of the separating plate can be arranged and/or guided, at least in sections, in a recess on an inside of the cover.
- the recess may comprise the bearing portion of the lid, the bearing portion extending through a through-hole of the main portion of the divider panel.
- the pin of the transport pawl can also extend through the through-hole to the outer surface of the cover.
- a spring-loaded flap at one foot of the sleeve channel ensures that the last ferrule of the belt strip does not jam in the sleeve channel.
