Description

Feeding device for conveying work carrier

The invention relates to a conveying device for conveying a workpiece, in particular a workpiece carrier, of the type described in the preamble of claim 1.

Such a conveying device for conveying a workpiece carrier is disclosed in DE 36 15 064. Such a conveying device has two parallel conveying tracks and a transverse conveying device arranged between these conveying tracks. The conveying tracks in this case have one outer conveyer belt with endless belts guided through the rollers and an inner conveyer belt with roller systems provided at predetermined intervals from the conveyer belt. The transverse conveying device has a support frame arranged between parallel conveying tracks. This support frame has a middle portion of immovability. Following this support frame, one end member supported rotatably is provided, respectively. This end member together with the carrying track form a delivery station. Each of these end members intersects the inner roller system of the conveying track and covers the free space between the roller system of the conveying track and the outer belt. Each of these end members is provided with one lifting device. This lifting device allows the end member to pivot to a plurality of different vertical positions relative to the carrying track.

In such a configuration of the transverse conveying device, the pivot axis of the end member which can be pivotally installed is spaced a predetermined distance from the inner roller system so that it can pass through the roller system provided between the end members of the transverse conveying device. Must have In addition, there is a need for a configuration in which the components are concentrated in the turning area so that the belt of the end member can be driven. By dividing the transverse conveying device into an end portion and an intermediate portion, many different belt lengths are needed.

In addition, a conveying device for conveying a workpiece carrier is already known, comprising two parallel conveying tracks and a transverse conveying device provided therebetween. Such a conveying apparatus is formed as a single belt system. The transverse conveying device forming the carry-in track and / or the carry-out track has a rigid frame, which is movable up and down by one lifting cylinder each arranged in each end region.

In the case of such a single belt system, the workpiece must be placed in the workpiece carrier so that a uniform distribution of forces acts on the belt feeder track and the inner roller system. If the load distribution of the workpiece to the workpiece carrier is located more on the roller system, trouble-free operation in the loading and unloading of the workpiece carrier can no longer be guaranteed. The reason is that the frictional force acting between the workpiece carrier and the single belt can be reduced. As a result, the carrying belt is badly worn by friction.

2 is a schematic cross-sectional view of the lifting device with the transverse feeder tracks capable of moving up and down;

3 shows one working position of the transverse feeder track;

4 shows an alternative working position of the transverse feeder track.

5 shows yet another working position of the transverse feeder track.

An advantage of the conveying device according to the invention is to simplify the assembly of the integrally formed conveying device track and to shorten the assembly time. In addition, the module structure is provided by such a configuration. The integrally formed conveying device track is provided as a double belt conveying device. As a result, mechanical parts can be reduced. At the same time, reliable loading and unloading or reliable delivery of the workpiece carrier can be achieved. Since the feeder track is formed as a double belt feeder at the transfer station, and the workpiece carrier is to be transported transversely with respect to the feed direction from the double belt feeder, even if the load distribution of the work piece to the workpiece carrier is uneven, a reliable carry-out is achieved. Is done. At opposite ends of the end region the inner conveying device track is formed as short as the length of the conveying station. On the other hand, the passive roller system is provided in the free space between the feeder tracks provided in the transverse direction and formed as a double belt feeder. This roller system can be moved up and down together with the outer belt feeder track. Since the work carrier is already moved from the transfer station by the double belt feeder, even if a non-uniform load distribution occurs, the work carrier is reliably loaded into another feeder track which is installed transverse to the feeder track. This is because, unlike the prior art of the single belt system, the work carrier does not have to be taken out from the rest position.

The end regions of the import track and the export track are supported by the transfer station to move up and down in order to transfer the workpiece carrier from the import track and / or the export track into the main feeder track and / or the subfeeder track. It is possible to obtain an inexpensive configuration in which the components are reduced because the entire conveying device track is formed to have rigidity over the length of the import track and / or the export track. In addition, as the passive roller system is provided in the end region of the feeder track, the assembly becomes remarkably simple.

The advantageous arrangement of the transfer device according to claim 1 is obtained by the measures described in the dependent claims.

By the end regions movable up and down independently of the import track and the export track, an import process and / or an export process can be performed in one end region. Furthermore, in this case, the end region opposite to this is not affected during the import process and / or the export process. At the same time the end regions of the import track and the export track may take the position where the workpiece carrier passes through the transfer station. In this case the position does not have any effect on the opposite end regions. The vertical movement of the end region of the import track and / or the export track is performed by lifting elements respectively installed in the end region. It is advantageous if a cushioning element is provided between the lifting frame and the support frame of the import track and / or the export track. This allows the workpiece carrier to be cushioned in one conveying direction from another conveying direction transversely to it and conveyed with a low noise. Tilting moments which occur at the time of introduction into the transfer station and when the workpiece carrier abuts against the stopper blocking in the conveying direction and which act on the conveying device tracks installed transverse to the conveying direction can be intercepted and absorbed. In addition, the advantage of this cushioned support of the support frame is that compensation can be made in the tilting movement of the support frame since the lifting elements can be placed independently of one another in the lower, middle and upper vertical positions in each end region.

It is advantageous for the incoming and outgoing tracks that the end regions disposed opposite the passive transporter tracks have the ends of the transporter tracks formed of the same length. This allows both belt feeder tracks to fully enter the delivery station. This ensures a reliable carry out of the workpiece carrier. At the same time, the modular structure can be achieved by such a configuration.

The main and secondary feeder tracks have an end region opposite the passive feeder track, in which the inner conveyer track is at least outside of the loading and / or unloading conveyer track, in which the inner conveying track enters at least transversely into the delivery station. It is advantageous if it is as short as the track. Thereby, the module structure of a conveyance system can be improved further. At the same time, a reliable carry-out in the conveying direction extending transversely to the conveying direction of the workpiece carrier is carried out.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 shows a partial area of the main circulation track 10 of a conveying device with a forward conveying track 11 and a return conveying track 12 installed parallel to each other. One end change module 13 is provided at both ends of these forward conveyance tracks 11 and return conveyance tracks 12, respectively. The main circulation track 10 is formed of a plurality of main feeder tracks 20 to 23 provided before and after each other. Main feeder tracks 20, 21 and optionally additional main feeder tracks form a forward conveying track 11, and main feeder tracks 22 23 and optionally additional main feeder tracks comprise a return conveying track 12. ).

In this embodiment the conveying device with the forward conveying track 11 and the return conveying track 12 is formed as a double belt conveying device. Each conveying device tracks 20 to 23 have a unique drive for the conveying belt of the double belt conveying device, for example.

First and second subconveyor tracks 26, 27 are installed along the return transport track 12. These subfeeder tracks 26, 27 each have an export module 28 with an export track 29 which is a transverse feeder track and an import module 31 with an import track 32 which is a transverse feeder track. It is formed. The carrying out module 28 and the carrying out module 31 are installed at right angles, for example, between two main feeder tracks 22, 23. The feed station track 26 is provided with a machining station 33. In this machining station, the parts arranged on the workpiece carrier 35 are machined.

The main feeder track 22 and the subfeeder track 26 and the carrying out track 29 and the carrying in track 32 which are provided in parallel with this form one module 34. This module 34 is described in detail by way of example. A plurality of such modules 34 can be provided before and after each other. The main feeder tracks 20 to 23 thus arranged before and after each other form one forward conveying track 11 and a return conveying track 12 of the conveying device. The number of modules 34 can be selected according to the number of processing stations 33.

The unloading track 29 has an outer conveying track 36 and an inner conveying track 37 formed as a belt conveying device. A transfer station 38 is formed at the intersection of the main feeder track 22 with the end area 52 of the unloading track 29. In this delivery station both ends of the outer and inner conveying tracks 36, 37 are formed of the same length. Facing this, a transfer station 39 is formed between the end region 53 of the carry-out track 29 and the end region 52 'of the sub-conveyor track 26. In this case, the conveying tracks 36, 37 of the unloading track 29 are engaged with each other in a tooth-like manner to the outer conveying track 41 and the inner conveying track 42 of the subfeeder track 26. . The driven or active inner conveying track 37 is formed shorter than the outer active conveying track 36 of the unloading track 29, and from the front side towards the inner conveying track 42 of the subfeeder track 26. Is over. The inner conveying track 37 is supplemented by a passive conveying track area 43 at the transfer station 39 between the outer conveying track 41 and the inner conveying track 42 and thus passive with the inner conveying track 37. The conveying track area 43 has a conveying track of the same length as the outer conveying track 36.

This passive feed track area 43 is formed as a roller track. The passive transport track area 43 is provided at predetermined intervals with respect to the active inner transport track 37. This spacing almost corresponds to the width of the inner conveying track 42 of the subfeeder track 26. In the free space formed by this gap, the inner conveying track 42 of the subfeeder track 26 extends and ends on the front side toward the outer conveying track 36 of the unloading track 29. The outer conveying track 36 of the unloading track 29 is adjacent to the outer conveying track 41 of the subfeeder track 26 on the front side. The delivery station 39 is formed by such an installation and configuration of the end region 53 of the discharge track 29 and the end region 52 'of the subconveyor track 26. These end regions 53, 52 ′ engage each other in an orthodontic manner. The delivery stations 39, 51 are identically formed.

The advantage of the transport track 29 thus formed is that two driven or active transport tracks 36, 37 are installed at the time of transport of the workpiece carrier 35 from the transport station 38 to the transport station 39. This ensures a reliable release of the workpiece carrier 35 from the transfer station 38.

Upon introduction of the workpiece carrier 35 into the transfer station 39, conveying takes place via the active outer transfer track 36. The passive transport track area 43 in this case replenishes this end area parallel to this outer transport track. Since the workpiece carrier 35 is already moving in the conveying direction, an active feed track 36 is installed in the transfer station 39 to ensure that the workpiece carrier 35 is completely introduced into the transfer station 39. Is enough.

The end region 52 ′ of the subconveyor track 26 has an outer conveying track 41 and an inner conveying track 42 formed at different lengths in the conveying station 39. An additional transfer station 44 is provided which is located opposite the transfer station 39 in the conveying direction. In this transfer station, the workpiece carrier 35 is moved from the subfeeder track 26 to the loading track 32. This subfeeder track 26 has an end region 53 ′ of the outer conveying track 41 and the inner conveying track 42. This end region 53 ′ corresponds to the end region 53 of the discharge track 29 and forms part of the transfer station 39. The outer conveying track 41 extends throughout the subconveyor track 26. The inner conveying track 42 is adjacent to the inner conveying track 47 of the carry-in track 32 which is formed short and extends laterally with respect to the inner conveying track 42. Between the inner conveying track 47 and the outer conveying track 48 of the carrying track 32, a passive conveying track area 43 is provided in the extension of the inner conveying track 42.

This configuration of the intersecting area with the inner conveying track 57 and the outer conveying track 58 is also provided to the main feeder track 22 at the transfer station 51 of the import track 32.

By the end regions of the export and import tracks 29, 32 and the end regions of the main feeder track 22 and the subfeeder track 26 constructed in accordance with the invention, the transfer stations 38, 39, 44, 51 are provided. Clear export and import into the country are made.

In order to carry in and take out the workpiece carrier 35 by the loading module 31 and the carrying out module 28, the workpiece carrier is provided in the transfer stations 38, 39, 44, 51 so that it can move up and down. The up and down movement of the end region 52 at the transfer station 38 and 44 of the export track 29 and the import track 32 and the up and down movement of the end region 53 at the transfer station 39, 51 are lifted. Executed by the unit 54. This lifting unit is provided in the end regions 52, 53 and is shown in cross section in FIG. 2. This lifting unit 54 corresponds to a known block cylinder. This block cylinder is a double acting lifting cylinder. This lifting cylinder can move the end regions 52, 53 to different vertical positions. Alternatively, hydraulic, electromagnetic, or electrically driven lifting units may be provided.

2 shows the intermediate position of the lifting unit 54. In this intermediate position, for example, the workpiece carrier 35 introduced into the transfer station 38 can be stopped by the stopper 64. Since compressed air is provided to the lifting unit 54 to lift the workpiece carrier 35 from the main feeder track 22, the end region 52 is moved to the upper vertical position by a stroke distance 56. After the work carrier 35 is transferred from the transfer station 38, the lifting unit 54 can be displaced to an intermediate position as shown in FIG. 2. In this case, the lifting unit 54 may be in a pressureless state. The return spring 77 and the compression spring 78 can be in equilibrium and displace the base plate 59 supporting the end region 52 of the unloading track 29 to an intermediate position.

If the work carrier 35 has to pass through the transfer station 38, the second chamber of the lifting unit 54 is under load, so that the base plate 59 is moved to the lower position with a predetermined stroke 61. As a result, the end region 52 of the unloading track 29 falls down with the stopper 64, so that it can pass through the transfer station 38. After this is done, the lifting unit 54 can be switched to a pressureless state. This lifting unit can thus be displaced back to the intermediate position.

The outer and inner conveying tracks 36, 37 are respectively installed on the base plate 59 via the buffer element 62 or on the intermediate plate or adapter plate 63 installed on the base plate. Since these shock absorbing elements 62 are elastically formed, the shock absorbing support of the carrying out track 29 and the carrying out track 32 is performed. The shock absorbing element 62 may be formed of an elastic plastic, or may be formed of an air cushion or other shock absorbing element which cushions the transverse direction with respect to the conveying direction.

To carry out the workpiece carrier 35 from the main feeder track 22 to the take-off track 29, the stopper provided in the inner transfer track 37 because the end region 52 is displaced to an intermediate position in the transfer station 38. 64) block in the feed direction. The workpiece carrier 35 abuts the stopper 64. In this sudden stop movement, the end region 52 of the unloading track 29 is subjected to lateral forces. This lateral force can be absorbed and compensated for by the cushioning element.

In addition, this elastic compensation allows the end regions 52, 53 of the carry-out track 29 to be positioned independently of each other in different vertical positions. Such is because the shock absorbing element 62 is formed to be elastic and flexible in the conveying direction.

Instead of the transport track 37 area driven in the end area 52, similarly in the end area 53 of the export track 29 the passive transport track area 43 is displaced to a different vertical position.

3, 4 and 5 show different vertical positions of the end regions 52, 53 of the unloading track 29. This also applies to the import track 32. 3 to 5 show examples of possible arrangement relationships. The lower, middle and upper vertical positions of the unloading track 29 at the transfer station 38 are shown by way of example. As a result, the workpiece carrier 35 can be passed, stopped, or lifted on the main feeder track 22 so that it can be continuously transported laterally with respect to the main feed direction. The vertical position of the end region 53 at the transfer station 39 is arbitrarily selected.

3 shows a side view of the unloading track 29. This carrying track 29 has a drive device 66. This drive device drives the outer and inner conveying tracks 36, 37. In the end region 52 the carry-out track 29 is supported against the lifting unit 54 via the cushioning element 62. The end region 52 is arranged in the lower vertical position 67. In this vertical position the end region 52 is positioned until the stopper 64 protruding above the conveying planes of the inner and outer conveying tracks 36, 37 is below the conveying plane of the main feeder track 22. Descend to the bottom. In this lower vertical position 67 the workpiece carrier 35 can continue to move in the conveying direction through the transfer station 38.

As shown as an example, the end region 53 is deployable in the upper vertical position 71. The workpiece carrier 35 taken out at this position can enter the transfer station 39.

In FIG. 4 the end region 52 is displaced to an intermediate vertical position 68. This signal is output from the control device when the workpiece carrier 35 is to be transferred to the machining station 33 of the subfeeder track 26 via the unloading track 29. In the intermediate vertical position 68, the stopper 64 protrudes above the conveying plane of the main feeder track 22. The work carrier 35 is thus stopped at the transfer station 38.

The end region 53 is displaced to the intermediate vertical position 72 with respect to the upper vertical position 71 shown in FIG. The workpiece carrier 35 is thus placed on the subfeeder track 26.

In figure 5 it can be seen that the workpiece carrier 35 enters and is positioned within the transfer station 38 via a signal generator, not shown. Accordingly, the control device transmits a signal such that the end region 52 of the unloading track 29 is displaced to the upper vertical position 69. Thereby, the workpiece carrier 35 can be lifted by the transfer station 38 and conveyed in the conveyance direction of the unloading track 29.

After the workpiece carrier 35 is taken out of the transfer station 38 and the transfer station 39 obtains a signal through the signal generator that the workpiece carrier 35 is not positioned there, the end region 53 is at the top. Displaced to the vertical position 71, thereby allowing the workpiece carrier 35 lifted off the main feeder track 22 to enter the transfer station 39. As soon as the signal generator of the transfer station 39 recognizes that the workpiece carrier 35 is fully positioned in the transfer station 39, the end region 53 is displaced to the lower vertical position, so that the workpiece carrier is moved to the subfeeder track. May be disposed at 26 and then transported.

The import / export process as shown for the export track 29 in FIGS. 3 to 5 is similarly applied to the import track 32. The main feeder track 22 and the subfeeder track 26 remain at the rest position at this time.

Monitoring of the delivery stations 38, 39, 44, 51 is made possible by the signal generator. Similarly, a separating element may be provided in front of each transfer station 38, 39, 44, 51. These separation elements are combined with a signal generator that monitors the transfer stations 38, 39, 44, 51, so that trouble-free operation can be ensured.
