Transport device, in particular for a transfer station of a hook conveyor

The invention relates to a transport device, in particular for a transfer station of a hook conveyor for hanging on hooks Good according to the preamble of claim 1.

In known transport devices is often a disadvantage that the transport devices are designed only for a certain type of hangers - and their Bügelhakengeometrien. Geometrically very different hook shapes of hangers can not always be reliably detected and transported by known transport devices. Another problem with known transport devices is that the hangers and the goods hung on them are pivoted swinging about a vertical axis during transport. This is also undesirable since, for example, when transferring such a hanger to a hook conveyor its position relative to the hook conveyor is not always exactly determinable, so that a transfer to the hook conveyor can fail.

The object of the invention is to provide a transport device for hanging on hangers, especially hangers Good, with which a variety of different hangers with different clothes hanger hook dimensions is transportable. Furthermore, it is an object of the invention to provide a transport device in which the position of the hanger is always defined during the transport process and in particular an uncontrolled pivoting about a vertical axis is avoided. Another object of the invention is to provide a separating device with which any succession of hangers with different hanger hook geometries can be reliably separated.

This object is achieved with a transport device having the features of claim 1. With regard to the separating device, the object is achieved with a separating device having the features of claim 86. Advantageous embodiments are specified in the dependent claims respectively dependent on the independent claims.

In the following the invention will be explained in more detail by way of example with reference to the drawing. Show it:

A transport device 1 according to the invention (FIG. 1) has a slide rail 2 and a double chain conveyor designed as a circulation conveyor with two chain conveyors 3, 3a. The transport device 1 is arranged vertically below a hook conveyor 4 and together with it forms an overlay. gabestation for example ironing or hangers 16.1 hanging Good 17, which should be passed from the transport device 1 to the hook conveyor 4. The hook conveyor 4 has a transport rail 5, which is designed as a hollow profile rail and has a groove or a channel in which a traction means 62 (cf., FIG. 3), for example a chain, circulates for transport hooks 6. A plurality of transport hooks 6 is connected to the traction means 62. The transport hooks 6 are movable by means of the traction means 62 in a transport direction 7 and are arranged at a defined distance d from each other. The defined distance d between two transport hooks 6 is, for example, twelve chain links of the traction means 62 in the transport rail 5.

The slide rail 2 has a feed region 10, which preferably has a gradient and is designed as a chute. A valley area 11 and a driving area 12 adjoin the feed area 10, the valley area 11 forming the transition between the gradient of the feed area 10 and the pitch of the entrainment area 12. The transfer area 13 extends parallel spaced ^' below the transport rail 5 of the hook conveyor 4. The feed area 10, the valley area 11 and portions of the driving area 12, below a collision level 18th lie below a lower edge 14 of the transport hook. 6

The slide rail 2 has an upper edge or an upper boundary surface 15, resting on the hanger hooks 16, on which the material 17 to be conveyed is hung on hangers 16.1. The slide rail 2 is in the feed region 10, in the valley arch region 11 and at least in a partial region of the entrainment region 12, which is below the collision level 18. has a Gleitschienenunterwan- tion 20, a Gleitschienenoberwandung 21 and Gleitschienen- side walls 22. The slide rail 2 is with its Gleitschienenunterwandung 20 via a slide rail holder 23 with a device cheek 24th mechanically firmly connected. The device cheek 24 faces a second device cheek 26 symmetrically to a slide rail center plane 25. The hanger hook 16 of a clothes hanger 16.1 is therefore preferably in the corner between the Gleitschienenoberwandung 21 and the Gleitschienenseitenwandungen 22, so that the hanger hook 16 of a hanger 16.1 touches the slide rail 2 at least two places.

In an area above the collision level 18, the slide rail 2 of only 2 is substantially vertically extending _. Gleitschienenseitenwandungen 22 fork-shaped, so that between the Gleitschienenseicenwandungen 22 a free passage gap 22.1 is formed for the transport hooks 6 in the longitudinal direction of the hook conveyor 5. In this area, the slide rail 2 thus has neither a slide rail upper side wall 21 nor a slide rail underside wall 20, so that a free passage of the transport hooks 6 along the transport direction 7 is made possible.

With respect to a chain conveyor 3 of the double chain conveyor 3 and 3a, the further description of the transport device 1 is given in FIG. 1. In a side view of the transport device 1 according to the invention, a first deflection means 30 is provided in the region above the valley region 11, in the region of a free end 31 of the transfer region 13 a second deflection means 32 and in the region vertically above the Zuführbe- area 10 approximately at the height of the second deflection means 32, a further deflection means 33 is arranged. To the deflection 30, 32 and 33, a traction means 34 is arranged circumferentially. The deflection means 30, 32, 33 are designed as rollers or pinions. The traction means 34 is a chain and is driven along a circumferential direction 35, in particular driven by a motor.

The traction means 34 extends at least in the area of the valley arch area 11, the entrainment area 12 and the transfer area 13 in a side view parallel to the slide rail top wall 21. After the second deflecting means 32, the load-free run of the chain conveyor 3 extends a little adjacent below the transport rail 5 of the hook conveyor 4 In the transition area between the driving area 12 and the transfer area 13, it is optionally also possible to arrange a further deflection means, for example a deflection roller (not shown). In the area between the third deflection means 33 and the first deflection means 30, a tensioning means 36, for example a roller or a pinion, which is adjustable, for example, in a direction 37 perpendicular to the direction of rotation 35 of the traction means 34 in the region between the deflection means 33 and 30 is, so that the course of the traction means 34 between the deflection means 33 and 30 is variable such that a portion 34.1 of the traction means 34, for example, parallel to the Gleitschienenoberwandung 21 of the feed portion 10 extends. Thus, the inlet angle of the traction means 34 in the partial region 34.1 is adjustable relative to the slide rail 2.

The feed region 10 of the slide rail 2 has a separating device 110, which is arranged in the transport direction 7 in front of the region in which the chain conveyor 3 or the traction means 34 of the chain conveyor 3 runs adjacent or at the level of the slide rail top wall 21 of the slide rail 2. The separating device 110 divides the feed area 10 into a damming area 10.1 and a slip ramp area 10.2. In the impoundment area 10.1 slidably sliding a variety of hangers 16.1 can be dammed with them hung on 17 Good. The separating device 110, the function of which will be described below, ensures that from the accumulation area 10.1, the stirrups 16.1, with the goods 17 hanging therefrom, pass individually into the slip ramp area 10.2 of the slide rail 2.

In the view according to Figure 1, only a chain conveyor 3 is shown, the traction means 34 has the above-described course. According to the invention, two such chain conveyors 3, 3a are arranged symmetrically to the center plane 25 adjacent to the slide rail 2, so that in the view of Figure 1, a chain conveyor plane 50 (Figure 2a-2c) of the first chain conveyor 3 is arranged in front of the slide rail 2 and a second chain conveyor plane 50a of the second chain conveyor 3a is arranged behind the slide rail 2. The chain conveyor planes 50 and 50a are shown schematically in FIGS. 2a-2c and 3. In the chain conveyor plane 50 of the chain conveyor 3 runs with all the above elements. In the chain conveyor plane 50a runs a chain conveyor 3 identical to the chain conveyor 3a, which is identical to the chain conveyor 3 and is arranged symmetrically to the center plane 25. Both chain conveyors 3 and 3a thus run congruently in the view according to FIG. 1, so that the entire preceding description for the chain conveyor 3 also applies mutatis mutandis to the chain conveyor 3a. The components of the chain conveyor 3a are provided corresponding to the components of the chain conveyor 3 in each case with respect to their reference numerals with the addition "a". Thus, for example, the traction means 34 of the chain conveyor 3 corresponds to the traction means 34a of the chain conveyor 3a. The chain conveyors 3, 3a together form the double chain conveyor 3, 3a designed as a circulation conveyor. At the traction means 34 and 34a of the chain conveyors 3, 3a 1 carrier devices 39 are arranged at regular intervals (Figure 2a-2c, 3), which extend horizontally in the direction of the median plane 25 from the respective chain conveyor plane 50, 50a of the traction means 34, 34a , The entrainment devices 39, 39a are configured, for example, as driving pins, which each have a free end 40, 40a. The driving pins 39, 39a are otherwise fixedly connected to a chain link of the traction means 34, 34a and thus run with the traction means 34, 34a along the direction of rotation 35. At least in the region in which the traction means 34, 34a of the chain conveyors 3, 3a extend adjacent to the slide rail 2, the traction means 34, 34a are defined in traction means guides 41, 41a. The traction means guides 41, 41a are fastened to the guiding cheeks 26, 24.

The free ends 40, 40a of opposing drive pins 39, 39a have a distance from each other, which is preferably at least chosen so large that they correspond to the gap 22.1, so that between the free end 40, 40a of the drive pins 39, 39a, the transport hooks 6 can pass freely.

In particular, it is advantageous that the free ends 40, 40a of the drive pins 39, 39a extend directly adjacent to the slide rail 2 in the region of the slide rail top wall 21, but without touching them (see FIG.

In the region above the collision level 18, in which no slide rail top wall 21 is present, the drive pins 39, 39a preferably extend in the region of the free upper edges of the slide rail side walls 22 (see FIG. In any case, however, it must be ensured that the driving pins 39, 39a with their free ends 40, 40a so far spaced from each other, that a free passage of the transport hooks 6 is ensured. Thus, the driving pins 39, 39a together with the slide rail 2 make it possible to transport hanger hooks 16 of very different hanger hook geometries (see Figures 2a, 2b and 2c) with good hanging on hangers sliding on the slide 2, since the driving pins 39, 39a abut on both sides on a slide hook resting on the slide rail 2, in particular symmetrically with respect to the center plane 25, and move the latter slidingly on the slide rail 2 when the pull means 34 or 34a is moved in the direction of rotation 35.

Furthermore, it is essential that the two chain conveyors 3, 3a and their traction means 34, 34a are synchronously driven to each other, so that two opposing driving pins 39, 39a with respect to a common longitudinal axis in alignment with the direction of rotation 35 are movable. This ensures that a hanger hook 16 resting against a pin pair 39, 39a can be transported uniformly along the slide rail 2 without movement about a vertical axis 42.

According to the invention, the drive of the chain conveyors 3, 3a takes place synchronously with one another synchronously by means of a synchronous drive device 60. The synchronous drive device 60 is designed, for example, as a transfer case and designed in the design of a bevel gear. The transmission 60 is on the output side via a drive chain 61, 61a with each chain conveyor 3, 3a in conjunction.

The transfer case 60 will be explained in more detail below with reference to FIG. The gear 60 is located above the transport rail 5, in which the traction means 62 for the transport hooks. 6 running. The transport rail 5 has in a section a Dürrgriffsfenster 63, (see also Figure 1) which is penetrated by a drive pinion 64. The drive pinion 64 is connected to a transmission input shaft 65 in connection, which is rotatably mounted about a vertical drive axis 66. The transmission input shaft 65 has the bevel gear 64 opposite a bevel gear 67, which meshes with a corresponding bevel gear 68 of an output shaft 6.9. The output shaft 69 is rotatably mounted about a horizontal axis 69.1 and has at its first free end an output pinion gear 70. This output gear 70 is associated with the chain conveyor 3 and is connected to this via a chain drive 71 in connection. The chain drive 71 cooperates with a drive shaft 72, on which a drive pinion 73 is seated. At the other end sits on the drive shaft 72 as a drive pinion, the deflection means 32, which is in engagement with the traction means 34 of the chain conveyor 3. The drive shaft -72 is rotatably mounted in the device che 26 by means of a roller bearing 75 about a horizontal axis parallel to the axis 69.1.

Symmetrical to the median plane 25 sits on the drive shaft 69 corresponding to the pinion 70, a further pinion 70a, which drives the traction means 34a of the chain conveyor 3a via a corresponding chain drive 71a and a corresponding pinion 73a. This drive train for the chain conveyor 3 a is formed identical to that of the chain conveyor 3.

The drive shaft 69 is extended beyond the pinion 70a out and has at its free end a further output gear 80, which is connected via a further chain drive 81 with a drive gear or a drive pinion 82 in connection. The drive pinion 82 is seated on an eccentric shaft 83, which is rotatably mounted about a horizontal axis 84. The eccentric shaft 83 is rotatable in a bearing block 85. bar mounted, which is fixed to a bearing cheek 86. The bearing cheek 86 is spaced from the device cheek 24 a bit outside offset to this. Between the bearing cheek 86 and the device cheek 24, a plate-shaped control lever 87 is arranged, which is in communication with an eccentric 88 of the eccentric shaft 83. The control lever 87 is pivotally mounted about a horizontal axis 89 and is mechanically fixedly connected to an actuating arm 90. The actuating arm 90 is connected to the lever 87, for example by means of screws 90.1. The actuating arm 90 is formed cranked and extends from the lever 87 the chain conveyor 3a in the area of the separating device 110 under cross-up to the median plane 25 and is there with a release lever 91 of the separating device 110, which will be described in more detail below, in conjunction. The pinion 80, the chain drive 81, the pinion 82, the eccentric shaft 83 with the eccentric 88, the lever 87 and the actuating arm 90 thus form a drive device for the Ausheberhebel 91 of the separating device 110, which is thus also driven via the gear 60.

Thus, both the drive of both chain conveyors 3 and 3a of the transport device 1 and the drive of the separating device 110, which will be described in greater detail below, are mechanically coupled via the gear 60 to the traction means 62 of the hook conveyor 4. The mechanically strong coupling of the drive means in relation to the traction means 62 of the hook conveyor 4 has the particular advantage that both the separation of accumulating hanger hooks 16 in the stowage area 10.1 and the drive of the chain conveyors 3 and 3a, a mechanical fixed assignment with regard to their sequence of movements in response to the hook conveyor 4 have. Thus, by this central tap of the drive of the Transport device 1 as well as the separating device 110 ensures a reliable and repeatable safe supply of hanger hook 16 with eg 17 hung on ironing 16.1 Good to transport hook 6. This arrangement has a very high reliability and reliability and is operable even under difficult conditions with high reliability.

The separating device 110 will be explained in more detail below with reference to FIGS. 4-11. FIG. 4 essentially corresponds to the lower part of FIG. 3 and is shown somewhat enlarged so that the reference symbols from FIG. 3 have been adopted. FIG. 4 is a schematic sectional view in the feed region 10 of the slide rail 2, in the fall of which the separating device 110 is arranged. Inside the slide 2 sits the release lever 91, which has a Aushebervorsprung 92. Adjacent to the Ausheberhebel 91 sit stowage cheeks 93, 94. The stowage cheeks 93, 94 extend beyond the upper boundary surface 15 of the slide rail 2 a piece, so that incoming hanger hooks 16 can be held jammed by the stowage cheeks 93, 94. The stowage cheeks 93, 94 have a stowage edge 95 and a sliding ramp 96 (see Figures 5 and 6). The Staukarite 95 protrudes a piece over the top 15 of the slide rail 2, so that hanger hooks 16, which slide down in the Aufstaubereich 10.1 on the slide rail 2, abut the storage edge 95.

The release lever 91 is pivotally mounted about the axis 89 with respect to the slide rail 2. This pivot axis 89 is the axis about which the lever 87 is pivotally mounted with respect to the cheek 24.

The lever 87 is substantially flat-plate-shaped and has a closed recess 97, whose output Tietungsbegrenzungskante forms a control surface, which cooperates with the eccentric 88. The eccentric 88 driven via the chain drive 81 performs an eccentric movement along the circular path 98. Thus, by means of the eccentric 88, the lever 87 can be driven in a pivoting movement along the double arrowed direction 99 back and forth about the axis 89. Thus, the control surface of the recess 97 is constantly in contact with the eccentric 98, the lever 87 is biased counterclockwise about the axis 89 by means of a tension spring device 100. The lever 87 is, as described above, via the actuating arm 90, which is shown only schematically in Figure 5, with the release lever 91 in connection. In a starting position according to FIG. 5, the release lever 91 is arranged completely inside the slide rail 2. The release lever 91 has a lever arm 101, which is rotatably mounted at its free end 102 about the axis 89 in the slide rail 2. At the end 103 opposite the free end 102 sits on the release lever 91 at its upper edge 104 of the Aushebervorsprung 92, which is arranged in the initial position shown completely within the slide rail 2 and seen in the transport direction 7 is a piece in front of the stowage cheeks 93, 94. The free end 103 of the Ausheberhebels 91 is aligned with a first boundary edge 106 of the Aushebervorsprunges 92. Opposite the edge 106 of the Aushebervorsprung 92 is ramped by a sloping edge 107 sloping. The edges 107 and 106 converge towards each other in a side view and are rounded in a tip region 108 of the lifter projection 92. The edge 106 of the lifter projection 92 continuously merges into a boundary edge 109 of the lifter lever 91. The edges 106 and 109 together form a crowned end edge of the lifter lever 91. In the position according to FIG. 6, the lifting lever 91 is shown in its raising position, that is to say it is pivoted relative to the position from FIG. 5 along the direction of the arrow 120. The lever 87 is pivoted about the axis 89 by means of the eccentric 88 in the clockwise direction along the direction of arrow 99. The tension spring device 100 is stretched in relation to the position according to FIG. The upper edge 104 is aligned in a side view approximately with the upper edge 15 of the slide rail 2. The lifter projection 92 is moved between the stowage cheeks 93, 94 along the direction of arrow 120 upwards, so that the tip portion 108, the stowage cheeks 93, 94 projects a piece (Fig 6).

In the following, the lifting characteristic of the lifter lever 91 will be described with reference to FIG.

The spatial form of the recess 97 of the lever 87 is adapted to the eccentric 88 such that a jerk-free movement sequence of the pivoting movement of the lifter lever 91 is ensured. A suitable Aushebecharakteristik the Ausheberhebels 91 for an eccentric rotation is shown in Figure 7. The Aushebecharakteristik runs starting from a zero line 200 in an area up to 90 ° of an eccentric rotation arcuately rising and increases from about 90 ° eccentric rotation to slightly below 180 ° of the eccentric rotation linear. At about 210 °, the maximum Aushebhub 201 is reached.

This remains constant up to about 240 ° and then goes into a steep fall over. The steep dropping takes place approximately between 270 ° eccentric rotation and 300 ° eccentric rotation. Between 300 ° eccentric rotation and 360 ° eccentric rotation, the lifting stroke again reaches the zero line 200 in a continuous arc shape. The linearly rising course of the lifting stroke in the range between 90 ° and 180 ° is particularly preferred. rather than the linear return stroke in the range between 270 ° and 300 ° eccentric rotation. This results in a relatively gentle increase of the Ausheberhebels 91 and thus a relatively gentle lifting a to be singled hanger hook 16. After lifting a hanger hook 16 with the Aushebervorsprung 92 of the lifter lever 91 is relatively quickly accelerated or decelerated moved back to its original position shown in FIG.

In the following, the mode of operation of the separating device 110 will be explained by way of example with reference to FIGS. 8a-8c for a small bow hook cross-section. In FIG. 8a, the ejection lever 91 is in a starting position, so that the ejector projection 92 is arranged upstream of the stowage cheeks 93 and 94 below the upper side 15 of the slide rail 2 in the transport direction 7. At the stowage cheeks 93 and 94, a plurality of hanger hooks 16, for example, of different cross-sectional geometry arranged dammed, wherein the stowage cheeks 93 and 94 to be singled hanger hook 16 'rests with a relatively small hanger cross-section. In a next step according to FIG. 8b, the release lever is activated

91 actuated via the lever 87, so that the Aushebervorsprung

92 with its tip portion 108 to be singled hanger hook 16 'detected and moved along the chewing edges 95 a piece up until the hanger to be singled 16' on the ramp edge 96 of the stowage cheeks 93, 94 can slide in the transport direction 7. The rounding of the tip portion 108 is adapted to the smallest occurring hook bow cross section of a hanger hook 16 'such that a subsequent hanger hook 16''safely slides off the rounded tip of the Aushebervorsprungs 92 at the edge 106 and thus not together with the hanger hook 16' on the Stowage cheeks 93, 94 is lifted. In FIG. 8c, the release lever 91 has reached its end position according to FIG. The isolated hanger hook 16 'slips along the ramp edge 96 of the stowage cheeks 93, 94 and slides on the top 15 of the slide 2 from. The remaining stowed hanger hooks 16 are in this position on the edge 106 and remain dammed. Subsequently, by means of the drive for the ejection lever 91, the latter is moved into its basic position according to FIG. 8, from which a renewed singling process can be started.

With reference to FIGS. 9a-9c, a separation process will now be briefly described using the example of a hanger hook 16 'to be singled with a central hoop hook cross-section. In essence, the singling process for such a middle bow hook cross section is identical to that for a small bow hook cross section according to FIGS. 8a-8c, wherein a hoop hook of middle bow hook cross-section during lifting by means of release lever 91 essentially rests on the rounding of the tip region 108 of FIG Lift-out projection 92 is raised. Due to the gradient of the slide rail 2 in the region of the separating device 110, the hanger hook 16 is guided resting on the rounded tip region 108 and adjacent to the stowage cheeks 93, 94. After reaching the zenith of the stowage cheeks 93, 94 of the hanger hook 16 'to be separated slips analogously to the hanger hook with small cross-section according to the figures 8a-8c on the stowage cheeks 93, 94 and in the further course on the slide rail 2 from. The hanger hook 16 'following the hanger hook 16' to be singled is a bit further away from the stowage cheeks 93, 94 because of the slightly larger hanger hook cross section of the hanger hook 16 'to be separated in comparison to the situation according to FIGS. 8a-8c, so that the following hanger hook 16 '' occurs only in the region of the ktirnkanten 106 with the release lever 91 in contact. In the upper end position according to FIG. 9 c, the hanger hook 16 'to be singled with middle hanger hook cross-section slides analogously to the situation according to FIG. 8 c on the stowage cheeks 93, 94 and then on the upper side 15 the slide 2 from. Finally, the release lever 91 is again moved by means of the drive described above into the starting position or into the basic position according to FIG. 9a. Subsequently, a new separation process with the subsequent hanger hook 16 '' are initiated.

In the following a separation process for a large hanger hook cross-section will be explained with reference to the figures 10a-10c. The movement with respect to the lifter lever 91 is identical to that of the two above-described separation processes. In a basic position according to FIG. 10a, the lifting projection 92 comes into contact with the hook hook 16 'of large cross-section to be separated in the region of its rounded tip region 108, in which position the hanger hook 16' bears against the stowage cheeks 93, 94. At the hanger hooks 16 'to be separated, as in the above-described separation situations, there are further hanger hooks 16 of different cross section. In an intermediate position according to Figure 10b _/ in which the A.usheberhebel 91 is in a partially raised position, the rounding of the tip portion 108 of the lifting jack projection 92 is in the region of an underside of the ironing hook 16 'with a large hanger hook cross section to be separated. Furthermore, the hanger hook 16 'still abuts the stowage cheeks 93, 94 in this position. In contrast to the above-mentioned separation situations, the hanger hook 16 'with a large cross-section is still supported on a subsequent hanger hook 16''in such an intermediate position. The following hanger hook 16 '' prevents the hanger hook 16 'to be separated in this position from falling down against the transport direction 7, which would prevent separation or reliable lifting of the hanger hook 16' via the stowage ramps 93, 94. In the upper end position according to FIG. 10c of the release lever 91, the following hanger hook 16 "rests against the edge 106 of the release lever 91. Of the To be singled Bugelhaken 16 'passes due to the slope of the slide 2 of the tip portion 108 of Aushebervorsprungs 92 on the ramp edge 96 of the Stauangswargen 93, 94 and slips on this and subsequently on the top 15 of the slide rail 2 and is thus isolated.
