    Description FIELD OF THE INVENTION
    The present invention relates to a transfer device for the isolated transfer of product carriers with holding means to a suspension conveyor, a conveyor for conveying product carriers with holding means, with a transfer device and a suspension conveyor, and a method for operating the conveyor.
    BACKGROUND OF THE INVENTION
    In the field of materials handling, the selection and design of the conveyor systems and the conveyors mainly depend on the nature of the products to be conveyed. The products to be delivered may vary depending on the type e.g. be conveyed directly in suitable transport units of the conveyors or taken by suitable product carriers in the transport units and promoted. For certain requirements again no separate transport units are needed and the products or the product carriers can be conveyed directly in the conveyor. Frequently, conveying devices and / or conveying systems have, depending on the requirements, sections or regions of different conveying paths with or without product carriers, transport units, etc., between which transfer and / or feeding operations take place.
    When product carriers are used, depending on the nature of the coupling, the product carriers, e.g. via suitable holding means, to the conveyor or to the transport units of the conveyor special questions regarding the promotion, the transfer, the separation, etc. result. Such issues are of high relevance in the apparel industry, such as in collection warehouses, dispatch warehouses or dry cleaning, where the garments are conveyed by means of hangers of various kinds. As a rule, the hangers have hooks which engage in the conveying devices or transport units and thus provide the coupling between the product carrier and the conveying device or transport unit.
    EP 0 802 133 B1 describes a device for separating conveyor carriers with a rotatably driven threaded spindle, which increases thread pitch in the conveying direction, wherein the spindle is divided into several regions of different pitch. At least two different thread pitches are provided in each area, wherein, based on the conveying direction, the first thread pitch in each area is smaller in each case than the last in the preceding area, and the thread groove width of the threaded spindle increases in the conveying direction. It is further described an input device which consists of a separating device and one of these downstream transfer conveyor, wherein the conveyor carriers are transferred from the separating device via a slope on the transfer conveyor. From the transfer conveyor, the conveyor carriers are conveyed to a transfer point, where they slide over a slope in a conveyor pocket of a suspension conveyor.
    EP 1 914 182 B1 describes a feed-transport system for hangers with objects hanging thereon, in particular items of clothing, with a transport rail for receiving and guiding hooks of the stirrups, with one arranged at one end of the transport rail Transfer station for transferring each a strap on individually transportable holding elements, each having in its lower region a receiving opening for a hook of a bracket and with the transfer station associated transfer wheel. The transfer wheel in each case receives a holding element in a position in which it protrudes obliquely from the transfer wheel relative to the vertical, so that the receiving opening is open in a projection on the horizontal upward. By a transfer gap in each case cyclically a bracket falls down, which is caught by the receiving opening, since the free end of the hook is located above the receiving opening. The hook thus falls into the receiving opening and is thereby caught by the holding element.
    DE 4 326 095 C1 describes feeding devices on overhead conveyors for hanging on hanger hook goods, comprising on a support profile current, drawn by a traction device hook with a holding finger, a step conveyor for hanging on hanger hooks conveyed goods, e.g. Garments, a short transfer path in extension of the step conveyor with a U-shaped cross-section and a stop nose at the free end. The transfer track and the path of the conveyor hooks are at an acute angle to each other and the retaining finger dips into the groove between the U-legs, so that the retaining finger undercut a pending on the stop nose hanger hooks and can lift out over the stop lug. In the U-legs of the transfer track endless circulating, parallel conveyor belts are integrated, sit on the upper strand of the hanger hooks.
    PRESENTATION OF THE INVENTION
    In the promotion of products by means of product carriers with holding means is the reliable intervention of the holding means in the conveyors or transport units of the conveyors of great importance for the minimization of errors in the promotion of the products. In order to ensure a high delivery rate or conveying speed, reliable transfer processes and / or feed operations of the products or product carriers between different sections or regions of a conveyor system play an important role. For certain holding means, such as e.g. Hooks, additional requirements arise in connection with the separation of the products or product carriers, especially when the holding means tend to affect by mutual interaction, the flow rate.
    It is therefore an object of the invention to improve the state of the art of promoting product carriers with holding means, in particular the isolated transfer.
    This object is achieved by the features of the independent claims. Advantageous embodiments of the invention are given in the dependent claims and in the present description and the figures.
    The invention relates to a transfer device for the isolated transfer of product carriers with holding means to a suspension conveyor, comprising a conveyor coil which defines a conveying path for the holding means with a conveyor section and a transfer section, wherein the conveyor section in the conveying section describes a linear path and in the transfer section to linear path superimposed describes a transversely curved path.
    The conveyor coil has the advantage that a controlled promotion of the product carrier is made possible, especially for product carriers with holding means, which tend to uncontrolled movements, such as oscillations o.a., Execute. In the context of this invention, controlled delivery means a promotion of the product carriers, in which the product carriers describe a guided web, for example over a defined contact point on the conveyor spiral, and that e.g. Fall heights at handovers can be minimized or avoided. As a rule, with a controlled conveyance, the holding means or the product carriers essentially stop at the respective current position when the conveyor spiral stops and can be conveyed further away from this position upon resumption of the rotation of the conveyor spiral. In embodiments with hooks, which each rest on the conveyor spiral over a support point, the support point usually remains at the respective position when the conveyor coil stops, and the hooks can be further promoted from there on resumption of rotation of the conveyor coil.
    The conveyor line is usually defined by the shape of the Fördenwendel. Through such a defined conveyor line, the controlled promotion of the product carrier can be improved. The conveying section can advantageously serve to bring the product carriers onto the linear path of the conveying path along the longitudinal axis of the conveying spiral, on which the product carriers can be conveyed in a controlled manner. This may be particularly advantageous if the product carriers from another conveyor line, on which the promotion of the product carrier is controlled to a reduced degree, e.g. from a rail, on which the product carriers are conveyed freely running, reach the transfer device.
    Due to the transversely curved path of the conveyor line in the transfer section, the product carriers can be moved in addition to the linear movement along the longitudinal axis of the conveyor coil transverse to the longitudinal axis of the Fördenwendel, allowing a controlled transfer of the product carrier to a suspension conveyor, which, for example, in addition to the Fördenwendel, parallel to the conveyor coil or with the conveyor spiral enclosing an angle is arranged. In this context, transverse web is to be understood as meaning a web which lies in a plane perpendicular to the longitudinal axis of the conveyor helix.
    The transversely curved path can be described by a superposition of a horizontal and a vertical component in this plane, so that the transversely curved path in particular has a horizontal component, and thereby a controlled transfer to an arranged next to the transfer device hanging conveyor can be made possible ,
    Advantageously, in the transfer section, the transversely curved path superimposed on the linear path from the conveyor section that defined by the Fördenwendel conveyor section runs substantially along its entire route continuously and abrupt or discontinuous movements of the product carrier can be minimized or avoided.
    A particularly advantageous application of the invention is found in the clothing industry, where the product carrier is designed as a hanger and the holding means as coat hooks. The product carriers may also be bags or containers which have holding means, such as hooks. Often, the product carriers are transferred from a storage facility, such as a magazine, or other conveyor to the transfer device.
    In one embodiment, the product carrier, in particular hangers, passed over rails on the conveyor spiral. The product carriers can arrive at irregular intervals from the rails, which is usually the case with rails on which the product carriers are driven by gravity. Preferably, the product carriers transferred to the transfer device are separated and conveyed in a controlled manner by the delivery helix in such a way that the product carriers are conveyed on the delivery helix at a defined distance from each other.
    Preferably, the conveyor line is in the transfer section for a majority of or for all conveyor coil positions, i. Rotation angle of the conveyor spiral, each in a local minimum of the surface, preferably with respect to the longitudinal axis of the conveyor coil, in which the holding means of the product carrier are conveyed.
    In one embodiment, the conveyor coil on helical turns, in which the holding means of the product carrier can be promoted. The helical turns offer the advantage that defined contact points or engagement points are provided for the holding means of the product carriers, so that a conveying path can be defined. A helical turn generally comprises a helical base and helical flanks adjoining the spiral base. Holding means designed as hooks can, for example, rest in the spiral shelves, so that a contact point of a take is conveyed along the defined conveying path. The hooks can rest laterally against the helical flanks, with the hooks being able to be triggered and conveyed by the helical flanks along the conveying path during rotation of the conveying helix.
    By rotation of the conveyor spiral can therefore be achieved in the conveying section of the conveyor line a linear promotion of the product carrier along the longitudinal axis of the conveyor coil.
    In the transfer section, the rotation of the conveyor coil in conjunction with a specific shape of the conveyor coil in the transfer section, as will be explained further in the present description, bring about the additional transversely curved path of the conveyor line.
    In general, the conveyor coil is driven by suitable drive means, preferably electric motors.
    Preferably, a defined number of hooks or product carrier is promoted per Wendelgang. In an advantageous embodiment, a single hook or product carrier is conveyed per Wendelgang each. In a further embodiment, two hooks or product carriers are conveyed per spiral turn. Optionally, the defined number of hooks or product carrier per Wendelgang between the helical turns differ. For example, the helical turns may alternately feed one or two hooks or product carriers respectively. The helical turns therefore offer the advantage that the product carriers can be conveyed at a defined distance from each other without being strongly influenced by one another, e.g. by clashing, which allows an efficient separation of the product carriers.
    In one embodiment, the conveyor spiral at least one separating helical gear for singling of adjacent hooks, which has a different pitch to the other helical turns. Preferably, the separating helix has at least partially zero slope. The separating helix is preferably formed from a gradation in a helical flank of a helical turn over which gradation the two adjacent hooks can be spatially separated. The front hook with respect to the conveying direction can be further conveyed by the helical gear in the conveying direction, while the rear hook enters the separating helical gear.
    Due to the different pitch of the separating helical gear, the rear hook can be further separated spatially from the front hook. After one revolution, the rear hook spatially separated from the front hook can leave the singling helical gear and be conveyed further in the conveying direction.
    In one embodiment, the helical turns in an axial section on a trapezoidal profile. In this embodiment, the bottoms of the helical turns occupy the shorter base side and the helical flanks engage the legs of the trapezoid. In one variant, the conveyor helix also has a trapezoidal profile between two adjacent helical flanks of two adjacent helical flights in an axial section, wherein the outer surface of the helical conveyor projected onto the axial section occupies the shorter base side of the trapezoid.
    Optionally, the helical flanks are rounded. Preferably, the helical flanks are concavely rounded. This improves the secure positioning of the retaining means in the helical turns and therefore the controlled promotion of product carriers.
    In a further embodiment, the helical turns in an axial section on a pointed profile.
    The helical turns may alternately have pointed or trapezoidal sections in sections.
    In one embodiment, the conveyor coil ends in the transfer section in an eccentrically arranged guide tongue, which has a comparison in cross-section of the conveyor coil in the conveyor section tapered cross-section.
    The guide tongue has the advantage that a holding means can be guided until the transfer to the suspension conveyor or controlled promoted. By means of the eccentric arrangement, it is possible to ensure that a holding means conveyed by the guide tongue is deflected by the linear path of the conveying path and superimposed on the linear path describes a transversely curved path.
    The tapered cross-section has the advantage that a portion of the holding means can protrude in a transverse plane over the cross-section of the conveyor spiral, which in the transfer to the overhead conveyor, e.g. can be used for engagement with an intervention means.
    In one embodiment, the conveyor spiral in the transfer section on a transfer turnaround with a quasiantiklastischen surface, wherein the conveying path in the transfer section is so in the quasi-anticlastic surface that the holding means to a linear path superimposed describe a transversely curved path.
    A quasi-anticlastic surface is understood to be an area which, at a given point on the surface, has in each case two different directions, different in sign from the sign, i. E. concave in a first direction and convex in a second direction. The two directions need not be oriented perpendicular to each other. Advantageously, the conveyor line during rotation of the conveyor spiral comes to lie in the quasi-anticlastic surface, that the conveyed during the transfer in Übergabewendelgang holding means in addition to the linear path describe a transversely curved path.
    Preferably, the transfer turnaround opens into the eccentrically arranged guide tongue, from which the holding means or the product carrier can be transferred to the suspension conveyor.
    Preferably, the surface of the transfer turnaround comprises a saddle surface with a helical principal direction.
    The helical main direction of the saddle surface offers the advantage that the holding means can be conveyed upon rotation of the conveyor spiral in a saddle point, which allows an improved controlled promotion.
    Along the main helical direction, the curvatures can vary along the direction perpendicular to the main direction.
    In one variant, the radius of curvature at the beginning of the transfer turning path coincides with the radius of the cross section of the conveyor spiral in the conveyor section and decreases to the end of the conveyor coil. The transfer turnaround can lead to an eccentrically arranged guide tongue with a circular segment-shaped cross section and a radius of curvature of the circle segment which is smaller than the radius of the cross section of the conveyor helix in the conveying section.
    The design of the conveyor spiral with the transfer turnaround with a saddle surface therefore offers the advantage that the holding means can be conveyed in a controlled manner, wherein the conveying path in the transfer section by the shape of the surface of the transfer turn and the rotation of the conveyor coil can describe a transversely curved path. Due to the controlled delivery, the transfer capacity, in particular the conveying speed, can be increased considerably.
    In one embodiment, the transfer turnaround on a coil depth, which is greater than half the core diameter of the conveyor coil in the conveyor section.
    In one embodiment, the conveyor spiral goes from the conveyor section continuously in the transfer turnaround in the transfer section.
    The continuous transition of the conveyor spiral from the conveyor section in the transfer turn in the transfer section has the advantage that the conveyor line can also be continuous and that abrupt movements of the holding means or the product carrier can be minimized or avoided.
    The invention further relates to a conveyor system for conveying product carriers with holding means, comprising a transfer device according to the present description, a suspension conveyor with a plurality of transport units for the product carrier, wherein the transport units have engagement means for the holding means of the product carrier, and the conveyor a Transfer area in which the product carriers are transferred from the transfer device to the overhead conveyor.
    In general, the suspension conveyor is arranged laterally on the transfer device, wherein the conveyor coil with an conveying path of the suspension conveyor in the transfer area include an angle or can be arranged in parallel.
    Preferably, the transfer region is formed by the transfer section of the conveyor coil and the conveying path of the suspension conveyor, which is arranged at the transfer section of the conveyor spiral. As a rule, a product carrier is transferred from the transfer device to the suspension conveyor device such that the holding means of the product carrier engages in the engagement means of a transport unit provided in the transfer area and the product carrier can be conveyed further by the transport unit in the suspended conveyor device.
    In one embodiment, the engagement means of the transport units are eyelets, in which the holding means, preferably hook, the product carrier can intervene.
    In one embodiment, the transport units in the transfer area are arranged inclined so that the openings of the eyelets are arranged perpendicular to the transfer direction of the holding means.
    In one embodiment, the suspension conveyor in the transfer area on a conveying path, which is arranged parallel to the conveyor coil.
    A parallel arrangement of the conveying path of the suspension conveyor in the transfer area and the conveyor coil has the advantage that the transfer area can be increased in comparison to arrangements in which the transfer device tapers at a large angle to the suspension conveyor. An enlargement of the transfer area along the conveying path offers the advantage that the time window for a possible transfer of the product carrier to the suspension conveyor can be increased, so that the transfer of the product carrier to the suspension conveyor can be better tuned, in particular by adapting the conveying speeds of the product carrier and the transport units.
    In one embodiment, the overhead conveyor on a running rail, wherein the transport units are on the running rail with variable distance from one another conveyable carriage.
    In one embodiment, the conveyor system has a controller which controls the transfer of the product carrier from the transfer device to the overhead conveyor.
    The controller may i.a. controlling the conveying speeds of the transport units and / or the product carriers, the provision of the transport units and / or the product carriers, etc.
    Preferably, the controller controls the overhead conveyor and / or the transfer device such that when transferring a product carrier in each case a transport unit is provided in the transfer area.
    In one embodiment, the conveyor system comprises a first drive unit for driving the conveyor coil and a second drive unit for driving the transport units in the transfer area, wherein the first and the second drive unit are controlled by the controller such that in the transfer area in the transfer of a holding means of the transfer device to the suspension conveyor each a transport unit is provided.
    In one embodiment, the first drive unit comprises a first drive coil, which is operatively connected to the conveyor coil. In a variant, the first drive helix engages in elevations between the helical turns of the delivery helix and can thus drive the delivery helix.
    In one embodiment, the second drive unit comprises a second drive coil, which is operatively connected to the transport units of the overhead conveyor. In a variant, the second drive helix has helical turns into which driver elements of the transport units can engage, so that the transport units can be conveyed along the conveying path of the hanger conveyor during rotation of the second drive helix.
    The control has the advantage that in each case a transport unit is provided during the transfer of a holding means and thus a reliable transfer of the product carrier is made possible by the transfer device to the overhead conveyor.
    In one embodiment, the controller synchronizes the conveying speed of the transport units with the conveying speed of the product carrier during the transfer.
    In embodiments with the first drive unit comprising a first drive coil and the second drive unit comprising a second drive coil, optionally the first drive coil and the second drive coil, e.g. via a belt, be operatively connected, so that the rotations of the first and the second drive coil are coupled.
    In one embodiment, the controller is designed to control the number of product carriers transferred per transport unit in the transfer area.
    This offers the advantage that, depending on the requirement, one or more product carriers per transport unit can be conveyed. For example, it may be advantageous to convey one garment top and one pair of pants in a set per transport unit. In one variant, the controller controls the number of product carriers transferred per transport unit by the controller having a transport unit wait in the transfer area until the desired number of product carriers are transferred from the transfer device to this transport unit.
    In one embodiment, a first sensor connected to the control is arranged on the conveyor helix, which can detect holding means of the product carrier on the conveyor helix.
    This offers the advantage that the controller can detect whether a holding means is conveyed to the transfer section and thus a transport unit is needed. If required, the controller can then provide a transport unit in the transfer area. The first sensor may be an optical sensor, e.g. a camera or photocell, or an inductive sensor.
    In one embodiment, a barrier element is arranged between a storage route of the suspended conveyor device and the transfer area, which is connected to the control for releasing one transport unit each upon detection of a holding means on the conveyor spiral by the first sensor.
    The accumulation section is preferably arranged upstream of the transfer area. The barrier element is designed to selectively block or release transport units. With the accumulation section advantageously the transport units can be stowed in front of the transfer area such that a controlled delivery of the transport units into the transfer area is made possible when a transport unit for a holding means or a product carrier is required.
    In one embodiment, the first sensor is designed to detect unwanted holding means of product carriers on the conveyor helix, wherein the controller is designed to activate the barrier element in such a way that the transport units are stowed in the jam line upon detection of unwanted holding means. By stowing the transport units in the jam line in detection of unwanted holding means on the conveyor coil, the product carrier with the unwanted holding means, instead of being transferred to transport units, be discharged.
    Furthermore, the controller is advantageously designed to disable the barrier element such that the jammed transport units released in time from the jam section and can be provided to take over subsequent product carriers with desired holding means in the transfer area.
    Preferably, the conveyor system comprises a collecting rail for discharging product carriers with unwanted holding means, wherein the collecting rail is arranged in the transfer area such that product carriers are transferred from the transfer device to the collecting rail, if no transport unit is provided in the transfer area. Due to the jamming of the transport units in the storage area in the detection of unwanted holding means on the conveyor coil, the product carriers can be discharged with the unwanted holding means by transfer to the collecting rail.
    Undesired holding means, i. those which are not to be conveyed by means of transport units on the overhead conveyor can, for example, be hooks which are adjacent or crossed, or those with empty product carriers, e.g. Hangers without clothes, his.
    The collecting rail is preferably designed such that the holding means of the product carrier can engage in the collecting rail. The collecting rail is preferably arranged inclined, so that the transferred to the collecting rail product carrier can be further promoted gravity driven.
    In embodiments without a catch rail, the unwanted holding means with the corresponding product carriers from the conveyor spiral into the void or into a collecting device, e.g. a box to be dropped.
    In embodiments with a separating helical gear, an additional sensor can optionally be arranged upstream of the separating helical gear, which at this point can detect unwanted holding means, in particular adjacent hooks on the conveyor spiral, wherein the first sensor is arranged downstream of the separating helix. Such an arrangement has the advantage that it can be detected by means of the first sensor, whether the juxtaposed hooks detected by the additional sensor could be successfully separated by the separating helical gear. If adjacent hooks could not be separated, this can be detected by the first sensor, so that these hooks or product carriers can be discharged.
    In one embodiment, downstream of the transfer area, a second sensor is arranged, which is designed to determine the number of holding means in each case in an engagement means of the transport unit.
    The second sensor may be an optical sensor, e.g. a camera or photocell, or an inductive sensor. In a controlled transfer of a certain number of product carriers to a transport unit can be checked by means of the second sensor, if the transport unit have actually been handed over the desired number of product carriers.
    In one embodiment, the conveyor system further sensors, which are designed to detect holding means and / or transport units at different areas of the conveyor system.
    In particular, a third sensor, which is designed to detect transport units in the accumulation path, can be arranged on the accumulation path. Preferably, the third sensor is connected to the controller. The third sensor has the advantage that it can be determined whether transport units are available in the buffer section, which can be dispensed into the transfer area if required.
    The invention further relates to a method for operating a conveyor system according to the present description, comprising the steps of: i) conveying the holding means of the product carriers on the conveyor spiral of the transfer device; ii) transfer of the product carrier from the transfer device to the suspension conveyor in the transfer area, wherein the holding means are conveyed in a controlled manner in the transfer in the engaging means of a transport unit.
    The controlled conveyance offers the advantage that during the transfer, conveying operations in which uncontrolled movements are favored, such as e.g. Fall events can be minimized or avoided.
    In one embodiment of the method, the holding means are in the transfer section of the Fördenwendel on a support point on the conveyor spiral, which differs from the defined by the longitudinal axis of the conveyor spiral vertical plane, such that a portion of the holding means, preferably a hook, in a transversal , Preferably oriented towards the overhead conveyor device, projecting direction beyond the cross-sectional area of the conveyor spiral.
    The over the cross-sectional area of the conveyor spiral protruding portion of the holding means can be advantageously used to introduce this section into an engagement means provided in the transfer area transport unit, before the holding means in the A handle intervenes and the product carrier is transferred to the transport unit. In this way, the controlled transfer can be improved. In particular, the drop height of the holding means can be minimized in the engagement means during the transfer and so minimized or avoided a fault.
    In the transfer, the holding means are preferably conveyed in such a manner that in each case a section of the holding means, preferably a hook, projects into the engagement means, preferably an eye, of a transport unit before the holding means leaves the transfer device and is transferred to the suspension conveyor ,
    In one embodiment of the method, the first sensor detects unwanted holding means of product carriers on the conveyor spiral and activates the barrier element in the detection of unwanted holding means such that the transport units are stowed in the storage area.
    By stowing the transport units in the jam line upon detection of unwanted holding means on the Fördenwendel the product carriers with the unwanted holding means, instead of being transferred to transport units, be discharged, for. by transferring the product carriers with the undesired holding means in the case of configurations of the conveyor system with a collecting rail, to the collecting rail.
    Furthermore, the controller may deactivate the barrier element in such a way that the jammed transport units can be released in time from the jam section and made available for transferring subsequent product carriers with desired holding means in the transfer area.

    DESCRIPTION OF EXEMPLARY EMBODIMENTS
    In order to illustrate the invention, preferred embodiments are described in detail with reference to the figures.
    1 shows a perspective partial view of an embodiment of a conveyor system 10. The conveyor system 10 comprises a transfer device 1 and a suspension conveyor 3 with a track 32, on which transport units (in the figure of the transfer device 1 hidden) are arranged. The transfer device 1 comprises a conveyor coil 11, on which hooks 21 b-e are arranged and which thus conveys the product carriers 2b-e. The product carrier 2a with the hook 21 a is already transferred to the suspension conveyor 3 and is no longer on the conveyor coil 11. The hook 21 a is therefore in engagement with an eyelet 311 of a transport unit. The conveyor coil 11 is driven by a first drive coil 101. A second drive coil 102, which drives the transport units of the suspension conveyor 3, is also shown.
    FIG. 2 shows a perspective view of the conveyor system from FIG. 1 about the transfer area T. The conveyor coil 11 of the transfer device 1 has a transfer turnaround 112 which ends in an eccentrically arranged guide tongue 111. The transfer turnaround 112 has a quasi-anticlastic surface in the form of a saddle surface with a helical principal direction. In Übergabewendelgang 112 is the hook 21 b, which rests in a saddle point of the saddle surface. The product carrier of the hook 21 b is not visible in the figure. By rotating the conveying helix 11, the hook 21b describes, in addition to a linear path along the conveying helix 11, a transversely curved path by means of which the hook 21b is conveyed in a controlled manner in the direction of the hanger conveying device 3. The end of the hook 21 b protrudes into the eyelet 311 of a transport unit 31 provided in the transfer area T, which is a carriage movable on the running rail 32 of the hanging conveyor 3. In the figure, two further subsequent carriages are shown, which are partially covered by the conveyor coil 11. Behind the hook 21 b are hook 21 c, 21 d and 21 e of the product carrier 2 c, 2 d and 2 e arranged on the conveyor coil 11.
    FIG. 3 shows a side view of the conveyor system from FIG. 1 about the transfer area T. The conveyor coil 11 of the transfer device 1 has helical gears 113 with helical flanks 114. The conveying helix 11 defines a conveying path for the hooks 21b-d with a conveying section FF and a transfer section FU. In the transfer section FU is the transfer turnaround 112, which opens into the guide tongue 111. In the conveying section FF, the hooks 21 c and 21 d are conveyed by rotation of the conveying helix 11 on a linear path along the longitudinal axis of the conveying helix 11. The linear path of the conveyor line in the conveyor section FF is schematically illustrated by the arrow F. In the transfer section FU, the rotation of the delivery helix 11 leads to a transversely curved path of the hook 21 b superimposed on the linear path along the longitudinal axis of the delivery helix 11. The hook 21 b is located in a local
    Minimum of the surface of the transfer thread 112 with respect to the longitudinal axis of the conveyor coil 11. The transport units 31 are arranged on a conveyor line FH of the overhead conveyor, which is arranged parallel to the conveyor coil 11 in the transfer area. In the figure it can be seen how the transfer thread 112 of the transfer section FL) continuously merges into a helical passage 113 of the conveying section FF.
    FIG. 4 shows a frontal view of the transfer region T of the conveyor system from FIG. 1. The eccentrically arranged guide tongue 111 with a circular segment-shaped cross section can be seen. The radius of curvature of the circular segment-shaped cross section of the guide tongue 111 is smaller than the radius of the cross-sectional area of the conveyor coil 11. It can be further seen how the transfer thread 112 continuously opens into the guide tongue 11. The hook 21 b, which is located in the transfer thread 112, protrudes with one end into the eyelet 311 of the transport unit 31 of the suspension conveyor 3, while the hook 21 b rests on the guide tongue 11. By rotation of the conveyor spiral 11 in the direction of the arrow P, the hook 21b is transferred from the guide tongue 111 in the direction A into the eyelet 311. The running rail 32 is arranged in the transfer area such that the transport unit 31 is inclined and the opening of the eyelet 311 thereby is substantially perpendicular to the direction A, which facilitates the transfer of the hook 21 b.
    Figures 5a-5h show a schematic representation of the transfer section in a front view of the conveyor coil 11. The figures show the conveyor coil 11 with the transfer turnaround 112 and the guide tongue 111 for different angular positions of the conveyor coil 11, which in the direction P of the arrow, as in Fig. 5b shown, rotated. The transfer turnaround 112 has a saddle surface-shaped surface. In order to illustrate the transversely curved path of the conveying path superimposed on the linear path in the transfer section of the conveying helix 11, the contact point AP of a hook 21 located in the transfer turn 112 is shown for the various angular positions of the conveying helix 11. The transversely curved conveying path is schematically illustrated by the curved arrow F. In Fig. 5a, the hook is just before entering the transfer section of the conveyor coil 11 and is located with the support point AP on the helical gear 113, which adjoins the transfer turn 112. After entering the transfer section, the support point AP lies on a saddle point of the surface of the transfer turnaround 112. It can be seen that the contact point AP of the hook 21 shortly before entering the transfer turnaround 112, as shown in Fig. 5a, in the is defined by the longitudinal axis of the conveyor spiral 11 defined vertical plane. Shortly before being transferred to an overhead conveyor, as shown in FIG. 5h, the support point AP deviates from the vertical plane such that a section 211 of the hook 21 projects beyond the cross-sectional area of the conveyor spiral 11 in the direction A of transfer, so that the section 211 can engage in an opening provided in the transfer area eyelet of a transport unit, before the guide tongue 111 by further rotation of the conveyor coil 11, the hook 21 releases.
    1 shows the first drive coil 101 and the second drive coil 102. The first drive coil 101 has helical turns 1011 which engage in elevations 115 of the conveyor coil 11 and pass through Rotation drive the conveyor coil 11. The second drive coil 102 has helical turns 1021, which engage in carrier elements of the transport units 31 and thus can drive the transport units 31 along the running track (hidden in the figure).
    Also to be seen in the figure is a first sensor 103, which is arranged in a rear region of the conveyor spiral 11 and can detect hooks on the conveyor coil 11.
    Fig. 7 shows a rear perspective view of the conveyor system of Fig. 1. It shows a transport unit 31, which is located in a buffer line S of the overhead conveyor. A barrier element 104 holds the transport unit 31 in the buffer path S. Upon detection of a hook on the conveyor coil by the first sensor, the barrier element 104 releases the transport unit 31 from the buffer path S, so that the transport unit 31 can be conveyed into the transfer area.
    Fig. 8a-c show side views of an embodiment of a conveyor coil 11 'with a separating helical gear 116 for different positions of the conveyor coil 11 Mn of the position shown in Fig. 8a position of the conveyor coil 11' is the separating helical gear 116 between the helical gears 113a and 113b and has in the section shown on a zero slope. The conveyor coil 11 'rotates in the direction of the arrow Q. The conveying direction is indicated by the arrow G. Hook 21 f and 21 g are on the conveyor coil 11 'at a position adjacent to each other, in which the separating helical gear 116 is formed from a gradation of the helical flank 113 a 1. By the separating helical gear 116, the hooks 21 f and 21 g are spatially separated, which can be seen in Fig. 8b, which shows the conveyor coil 11 'after half a revolution with respect to the position in Fig. 8a. Due to the spatial separation of the hook 21 f can be further promoted in the direction G. The hook 21g is located in the separating helical gear 116 and describes an additional loop around the conveying helix 11 '. In Fig. 8c, the Fördenwendel 11 'is again shown in the position of Fig. 8a, wherein the hook 21 f is spatially separated from the hook 21g in the helical gear 113b and is conveyed in the direction of G. The hook 21 g is located at the point of the Fördenwendel, in which the separating helical gear 116 coincides with the helical gear 113 a. Since the hook 21g is isolated at this point, i. If there is no hook in front of it (as is the case in FIG. 8 a), the hook 21 g can be conveyed in the direction of G through the helical gear 113 a without entering the singling helical gear 116.
