    Description: [0001] The invention relates to a device for separating and conveying piece goods from a bulk container to an issue position, according to the preamble of claim 1, and to a device for applying cable grommets to a cable, according to the preamble of claim 10.
    Such containers are widely used in conjunction with devices for applying cable grommets to a cable, wherein a plurality of loose cable grommets are provided in the container to be separated by a conveyor and transported to a mounting location for mounting the conveyed cable grommets on the cable become. For example, are known Saugblasförderer, but they are relatively loud and require relatively much energy for their operation.
    Typically, such devices include a vacuum sucking the piece goods and the general cargo conveying fluid flow generating vacuum nozzle near the bottom of the bulk container. This nozzle has a substantially vertically upwardly directed outflow direction. Furthermore, a fluid-permeable collecting tray for the piece goods is arranged above the delivery position for the piece goods.
    WO 9 708 787 A1 discloses such a device for conveying and for the arrangement of seals which are attached to a conductor - for example a light guide. The device shows a sorting unit with a container, in whose lower part a channel runs, which sucks the seals via a venturi mechanism and transports them by means of air flow into the upper part. The seals then fall on a partition wall between the upper part and the lower part. This wall has a hole with an adjustable passage cross section, through which hole the seals fall on a seal conveyor unit or past it and back into the lower part. The amount of seal is adjusted with a special mechanical solution, which is complicated and expensive and requires an additional actuator.
    In WO 2011 158 145 A1 another type of conveyor is disclosed which comprises an endless, annular, projecting into the bulk container conveyor with attached to the inside of said ring receiving means for receiving the cable grommets. In such systems, the individual parts of the bulk material can be clamped between the moving parts, which can lead to damage of the bulk material and / or damage to the system.
    For the pure transport, but without the required in particular for the Tüllenbestückung separation and transfer to another conveyor to enable the EP 023 905 A1 describes a device for distributing and transporting solid particles. This includes a fluidization chamber into which the particulate matter is introduced and directed within the fluidization chamber in a predetermined direction. In this case, a Coanda nozzle is used to entrain the solid particles.
    The object of the present invention was therefore an apparatus for separating and conveying piece goods from a bulk material container, with which a trouble-free and quiet operation with energy-efficient promotion and separation of the bulk material is possible. The same task is to be solved for a device for applying cable grommets on a cable.
    These objects are achieved by the features of the characterizing part of independent claims 1 and 10. Further features are contained in the subclaims and also the description and the accompanying drawings.
    According to the invention, the device for separating and conveying piece goods from a bulk container, characterized in that the collecting plate is impermeable to the cargo and with the horizontal angle not equal to zero includes, in particular an obtuse angle. With such a system can be small to medium-sized cargo such as cable grommets promote mechanical stress and without risk of pinching. The air and energy consumption is lower than in known designs and can be accurately controlled in time. The amount of seals transported to the dispensing point is controlled solely by controlling the valve, which controls the flow of air to the nozzle, so that no additional equipment is necessary. Typically, the trapping sheet will be substantially perpendicular, i. with the horizontal include a substantially right angle and it will impinge the air flow substantially perpendicular to this tray.
    Preferably, the vacuum nozzle according to the Coanda principle, designed as Venturi nozzle or vortex nozzle.
    A further embodiment according to the invention provides that the dispensing position and the collecting plate are arranged in the uppermost region of the device. Thus, the entire underlying area of the device for the provision of the seals is available, so that the device can be kept very small and compact. Even then, the transfer of the conveyed from the bulk container and isolated parts are simplified to a device for further transport.
    Preferably, the interior of the bulk container is kept free of internals that interfere with or prevent the formation of an annular fluid flow from the vacuum nozzle to the collecting tray, further back to the bottom of the bulk container and back to the vacuum nozzle. In particular, horizontally extending subdivisions are avoided, on the one hand not to hinder the high bubbles or the Mittransport the Seals in the fluid flow to the issue position, and on the other hand also not to hinder the relapse of not transported away Seals in the bulk container. Blockages can not occur at all.
    If, according to a further variant of this embodiment, at least the collecting plate and the inflow opening of the fluid passage, preferably also arranged the output position for the individual cargo, viewed from the vertical direction offset from the discharge opening of the vacuum nozzle, the falling back of subsidized parts of the bulk material in the Prevents nozzle and thus the susceptibility to interference is further reduced.
    According to a further embodiment of the invention is removed from the vacuum nozzle and substantially at the same height so that a blowing nozzle with preferably variable outflow direction available. Preferably, this nozzle is located on the opposite side of the device. Thus, a piece goods in the direction of the entrance of the vacuum nozzle directed and / or the cargo in the lower region of the device as well as the bulk container loosening air flow can be generated. Especially with low fill level, the suction of the piece good can be supported.
    A specific embodiment of the invention is characterized by an opposite of the bulk material filled with bulk material of the bulk container delimited fluid passage, which leads from a position downstream of the collecting plate into the region near the entrance of the vacuum nozzle.
    A further advantageous variant of the invention is characterized in that at least one outflow opening of the fluid passage near the suction opening of the vacuum nozzle and horizontally below it, wherein the diameter of each outflow opening is preferably smaller than the smallest dimension of the piece goods. This can, in particular at the beginning of the promotion of the bulk material, facilitates its loosening and movement of the piece good in the direction of the nozzle to be effected. By dimensioning the nozzle opening in relation to the size of the cargo parts of the entry of parts of the cargo is prevented in the outflow.
    Alternatively, according to the invention may also be at least a limited group of discharge openings of the fluid passage near the suction port of the vacuum nozzle and horizontally below it.
    The device as explained in the paragraphs above can be advantageously used in a device for applying cable grommets on a cable. Provided are a bulk container for receiving a variety of loose cable grommets and a device described in the preceding paragraphs for separating the cable grommets located in the bulk container and for conveying the isolated cable grommets to a mounting location and a mounting device for mounting the subsidized cable grommets on the cable.
    The invention will be explained in more detail with reference to the accompanying drawings.
    This shows the
    1 is a perspective view of an arrangement with bulk goods container for cable grommets, and an inventive device for conveying, separating and further transport of the cable grommets, according to the prior art,
    2 is a perspective view of an inventive arrangement for the same application,
    3 is a perspective view of the device of FIG. 2 for separating and conveying the piece goods located in the bulk container,
    4 shows a section through the device of FIG. 3 at the level of the center plane of the vacuum nozzle, and FIG. 5 shows a front view of the device of FIGS. 3 and 4.
    Shown in Fig. 1 is a conventional device as part of a machine for applying cable grommets on a cable. The cable grommets are received in bulk in a bulk container 1. A conveyor 2 receives via an opening 3 in the lower part of a partition wall 4 cable grommets and transports them in the vertical direction up to a transfer position in the upper region of the conveyor 2 to a device 5 for further transport to a mounting location for the cable grommets on a cable. The conveyor 2 has an endless, annular, projecting into the bulk container 1 conveying means, for example a rotating belt with blades for the bulk material, which conveying means via a drive 6 outside, preferably above, the conveyor 2 is driven.
    An inventive device 7 for separating and conveying piece goods from a bulk container to an output position can be used in a similar manner as the conveyor 2 in a machine for applying cable grommets on a cable, as shown in Fig. 2. Due to the lack of motor-driven movable conveyor complex and complicated drives 6 and the like. On the device 7 can be avoided, which also allows a more compact and störungsunanfällige design. The piece goods to be conveyed can enter the region of the device 7 in the same manner as described above through an opening 3 in a dividing wall 4 from the bulk material container 1 (see FIG. 3).
    In accordance with the invention, the device 7 has a vacuum nozzle 8 sucking up the piece goods. This is preferably carried out according to the Coanda principle, but may also be designed as a venturi nozzle or as a vortex nozzle. The vacuum nozzle 8 is preferably located near the bottom of the bulk container 1 or positioned substantially just above the bottom level thereof. When using a Coanda nozzle, with Wandhafthaftung a liquid or a gas jet at high speed to produce fluid movement in their environment, a small amount of compressed air, which is supplied via a line from outside the device 7, at supersonic speed by a pressed inner nozzle ring. This creates a vacuum which draws large quantities of the surrounding or "free" air through the nozzle 8 together with the piece goods. This principle has the additional advantage that when the air flow is blocked the flow is simply reversed, i. it creates a low back pressure.
    Since the dispensing position is typically in the uppermost region of the device 7, the longitudinal axis of the vacuum nozzle 8, which also defines the direction of the airflow conveying the article to the dispensing position, is substantially vertical and on the upper edge aligned with the bulk container pointing. It can - as can be seen in Fig. 4 - be slightly inclined to the vertical, the longitudinal axis then preferably has to the outside to produce a fitting against the wall 9 of the device 7 upwardly flowing air flow.
    In the area of the dispensing position in the piece goods in the conveying fluid flow, a fluid-permeable collecting tray 10 is arranged for the piece goods, on which this bounces and falls perpendicular down after the concomitant deceleration. Near the lower region of the collecting plate 10, the device 5 protrudes into the device 7 for the further transport of the cable grommets and takes over the falling parts of the piece goods. The collecting plate 10 may preferably be designed substantially perpendicular to the horizontal and also aligned perpendicular to the fluid flow funnel plate with a fine hole pattern or as a fine wire mesh. Thus, the collecting plate 10 is indeed permeable to the fluid flow, but not for the general cargo, which is taken out of the collecting plate from the fluid flow, braked and passed through the action of gravity on the output device positioned below it.
    In addition to the collecting tray 10, the interior of the device 7 is advantageously kept free of any fittings that could somehow hinder, distract or interrupt the flow of fluid. In particular, substantially horizontally extending subdivisions, partitions or the like are avoided.
    Of this uppermost portion of the device 7, in which the collecting plate 10 and the discharge position of the cable grommets is, according to one embodiment of the invention, a fluid passage 11 emanate from a position downstream of the collecting plate 10. However, this fluid passage 11 is not mandatory, but in their presence, it leads down the wall of the device 7 down to a height at ground level of the device 7 and the bulk material container 1. Preferably, the passage 11 continues to a region near the entrance of the Vacuum nozzle 8. Part of the circulating air flow is passed through this passage 11 and improves the delivery rate of the device 7 by supplying air suckable through the nozzle 8, especially when the fill level of the cable grommets exceeds the suction opening of the vacuum nozzle 8.
    To simplify the further transport of the piece goods, the dispensing position, the collecting tray 10 and an inflow opening of the fluid passage 11 are not only arranged in the uppermost area of the device 7, but are also viewed from the vertical direction with respect to the upwardly directed outflow opening of the vacuum nozzle. 8 staggered.
    At least one outflow opening 12 from this fluid passage 11 is located near the suction opening of the vacuum nozzle 8 and horizontally below it, as shown in Fig. 4. Preferably, the diameter of each outflow opening 12 is smaller than the smallest dimension of the piece goods. Alternatively, at least a limited group of outflow openings 12 of the fluid passage 11 may be near the suction opening of the vacuum nozzle 8 and horizontally below it.
    By the vacuum nozzle 8, preferably in cooperation with the or the outflow openings 12, there is a substantially annular circulation of the cargo promoting the cargo within the device 7. In this case, the air with the cargo from a level below the inlet opening of the vacuum nozzle Sucked 8, accelerated through this nozzle 8 upwards and blown into the upper part of the device 7. There, the deflection takes place with simultaneous transfer of the piece goods to the device 5 for further transport, and the further flow of air on the nozzle 8 opposite side of the device, in particular through the passage 11, back into the lower region of the device.
    Finally, an additional blowing nozzle 13 may be present and blow air into the cargo in the lower part of the device 7. The tuyere 13 is supplied via a line from the outside of the device 7 with compressed air. Thus, the cable grommets can be blown onto the opening of the vacuum nozzle 8 or can be loosened from the bulk material container 1 in the lower portion of the device 7 arrived cargo with it. Preferably, the direction of the tuyere 13 is adjustable, typically it is oriented downwards.
    To guide and improve the directed from the vacuum nozzle 8 upward air flow with the isolated and promoted cargo can connect above the vacuum nozzle 8 and parallel to the wall 9, a baffle 14 or a fireplace. This guide plate 14 is arranged obliquely in the upper region of the device 7, that
