Description

The invention relates to a multi-station press several, one after the other according to a processing sequence arranged press stations.

Multi-station presses, both as a single machine as well as a system of directly linked presses can be built up are common, especially if they are coordinated in a given work cycle work, linked together via a transfer system, the workpieces from one press station to the next Press station transported on. The press stations are provided with tools for each machining workpiece type are set up. To the Transfer systems are also for the special to be processed or workpiece to be transported Gripper means provided.

Should the multi-station press be used to machine a be set up by a special workpiece or by a Workpiece can be converted to another workpiece, are the workpiece-specific parts of the press stations and to replace the transfer system. This should be as possible done quickly and automatically.

DE 38 43 975 C1 is a transport device known for larger workpieces in a step press. The Step press has several, along a transport direction arranged and spaced-apart press stations in which are intended to hold the workpieces Matrices or lower tools on sliding tables are arranged interchangeably. Above the sliding tables are vertically up and down movable plunger provided are driven in unison. Each pestle is with one Upper tool provided and defined with that on the sliding table arranged lower tool a press station. For workpiece transport between the press stations a cross-beam transfer device is provided, the has two mutually parallel transport rails. The Transport rails are on both sides of the press stations over the entire length of the step press and connected to each other by cross beams. The crossbeams are detachable with the coupling devices Transport rails connected. Between the press stations So-called locking pins are arranged, each are connected in pairs with a sliding table and the Serve to hold crossbars to be replaced. To the Retrofitting, i.e. to replace the workpiece-specific Parts of the press, the crossbars on the locking pins stored and with the sliding tables on the side drove out of the press.

With this press, the design must be based on it It should be borne in mind that those between the Sliding tables arranged and each with a sliding table connected bolts from the side of the press can be pulled out. Therefore, neither in the stand area Sliding tables still connected with these pins to be ordered.

From DE-PS 36 07 323 is a press line with Single presses known in which the workpiece transport is accomplished by gripper rails. To an automatic The presses are to enable the conversion process equipped with sliding tables that run across the direction of transport the parts through the press stands of the press can be extended and retracted. With the respective The sliding table is used to machine the workpieces serving tools replaced. The one for transfer provided gripper rails have parts-related gripper rail parts on, each for the transportation of the transporting special part are set up. Around to enable a change of these gripper rail parts, are divided into three parts and can be detached with the gripper rail connected. The gripper rail parts are included the grippers, which with the respective workpiece in To be engaged during the continuous sections the gripper rails only as a carrier for the Serve gripper rail parts. The gripper rail parts of a middle part and two of these adjacent outer parts formed. The outer parts are in Can be moved telescopically with respect to the respective middle section, being used to drive the same piston-cylinder units are provided.

To replace the gripper rail parts, the External parts by means of the piston-cylinder units in the direction adjusted to the middle section, after which the one Unit-forming gripper rail parts on a corresponding The slide table is stored and removed from the Press are driven.

The overall not inconsiderable weight of the gripper rail parts and the piston-cylinder units driving them increases the weight of the gripper rails.

A transfer press system is known from US Pat. No. 5,248,288 with several successive press stations known, via a cross-beam transfer device are linked together. The cross-beam transfer device has two parallel and synchronously driven transport rails between which crossbeams extending transversely to the transport direction are hung. The crossbeams are over Coupling means connected to the transport rails and if necessary, detachable from these. In every press station a sliding table is provided, by means of which the forming tools Can be moved laterally out of the press area are. Each sliding table is with a cradle for crossbeams detached from the transport rods provided in one with the adjacent sliding table defined space is arranged. This Cradle contains two telescopic cylinders that by means of a lever parallelogram parallel to the sliding table are pivotable and adjustable in height.

The receiving device takes the tool change Cross beams from the transport rails and folds the Crossbeams on the tools lying on the sliding table approach to a compact arrangement of the to be replaced Tools to achieve. This kind of changing the Gripper means and the tools set a transfer device with crossbeams ahead, at the gaps exist between the sliding tables.

A transfer device is known from DE 43 09 643 A1 for workpiece transport, which is a three-axis transfer is trained. The conversion device is on a press with several press stations and has two spaced parallel across the entire length the transport rails extending on the press. This are moved synchronously in and against the transport direction and if necessary via appropriate lifting devices raised or lowered. In addition, the transport rails towards and away from each other. Carrier rails are carried by the transport rails, which provide gripping devices for the workpieces are. There are storage supports on each sliding table to accommodate them provided by support rails. Around the support rails separate from the transport rails and on the shelves discontinue, especially those located in the stand area Carrier rails by means of the transport rails from the Stand area out and in the appropriate storage position moved and aligned with the sliding tables discontinued. In this position, the support rails can with the sliding tables and the ones placed on them Tools are moved out of the side of the press.

Particularly with presses with several, relatively tight stands that stand side by side are to the side Moving out the necessary passages a relatively limited in size, causing problems can lead.

Based on this, it is an object of the invention to Multi-station press with a transfer device create when both machining workpieces serving tools as well as for transporting the workpieces serving gripper means provided on the transfer device are automatically exchangeable in a simple manner, without additional space for moving the transport rails or to move the sliding tables out to the side to require. It is also an object of the invention a procedure for changing the gripper means To create tool changes that meet the requirements mentioned enough.

This task is accomplished with a multi-station press the features of claim 1 and by a Method with the features of claim 16 solved.

The multi-station press, which is a single machine or a sequence of several, through the transfer device together linked, pressing can be with sliding tables provided that can be moved out of the side of the press and allow a quick tool change. The Transfer device has two mutually parallel transport rails on which spaced-apart carrier means are carried, which in turn with gripper means are provided for the workpieces. The vehicles are detachable from the transport rails, being on the sliding tables Pick-up means for picking up the carrier rails are arranged. While the carrier means on the transport rails each spaced apart are the receiving means of the sliding tables ensure that the carrier means can be placed close together are, whereby they are not in alignment. Two on the transport rail adjacent carrier means go through a longitudinal stroke during their transfer movement, the their own length plus the distance to corresponds to the next adjacent carrier. Both carriers can be on the sliding table in one Area to be accommodated, its in the direction of transport measured longitudinal extent does not exceed the stroke length and preferably a maximum of one Carrier. This can be due in particular to overlapping Arrangement of the carrier means can be achieved by this e.g. stacked one above the other. Such Storage of the carrier means enables the inclusion of additional carriers, which are then required in particular if clipboards are between the sliding tables are arranged. Each transport rail then carries two carriers per sliding table.

Due to the space-saving inclusion of the Carrier means on the sliding tables, it is possible to Stator area located by means of a Longitudinal movement of the transport rails from the stand area drive out and on appropriate holding means of the sliding table to overlap each other. there can a sliding table on each side, for example Arrange arranged carriers that do not have protrude this. It can therefore easily move sideways be moved out of the press area, even if the available passage through neighboring Press stand is constricted.

In addition, no means are required around the carrier means a longitudinal movement with respect to the Issue transport rails, reducing the mass of the Carrier means and transport rails and thus the occurring Acceleration and braking forces remain within limits. This is particularly so with regard to the drive device an advantage for the transport rails.

A particularly space-saving arrangement of the carrier means on the sliding tables results when the carrier means parallel to each other, side by side or one above the other are held. If the carrier means in each case have a low height, it is ensured that the already existing height adjustability of the transport rail sufficient to hold the carrier on the receiving means store. This is preferably done without drive means would be provided for the carrier means, i.e. the carrier means are purely passive, what their Keeps weight relatively low.

For fastening the carrier rail to the transport rail is preferably one acting between them Locking device is provided, which serves the Gripper means during normal operation of the transfer device, i.e. for workpiece transfer, stationary on the transport rails to couple. Once the carrier from the Receiving device recorded and form-fitting with this is connected, the locking device goes in Release position so that the transport rail through detach a suitable longitudinal movement from the carrier means and can separate.

The receiving device, for example, also rigid can be, is preferably pivotable on the Sliding table mounted. This makes it possible to use the receiving device after delivery of the vehicle swing away sideways so that the gripper means from the Tool area and the carrier means from the range of motion the transport rail can be moved out.

The from the transport rails of the drive unit and the transfer unit formed by the gripper means is preferred trained as a three-axis transfer, in which the Transport rails parallel to each other and parallel to the transport direction are arranged and in the transport direction, i.e. horizontally, vertically and towards each other and can be moved away from each other. With such a The three-axis transfer is the transfer of the Carrier means held on the corresponding rails Pick up on the sliding tables on special simple way using the three-axis transfer to Introducing and hanging the carrier means in the receiving means without the aid of additional drive units possible.

This is done according to the method also claimed first of all by means of a transport rail Support means to be received in a side Deposit movement inserted into the holding device, after which the transport rail preferably in a combined Feed / lower movement separated from the carrier means becomes. Then the transport rail carries the rest the holding means to be connected and put this on her. The carrier can be tight together and therefore very space-saving on the sliding table being held.

the press station of FIG. 3 in a schematic and partial cross-sectional view, with different work steps of the tool change.

In Fig. 1 is a multi-station press 1 in the cutout shown, the five along a transport direction T press stations 11, 12 arranged one behind the other 13, 14, 15. The multi-station press 1 is included only shown in sections and their machine frame is indicated on the basis of press stands 17 which on both sides of that determined by the transport direction T. Workpiece transport path set up in a row are. To differentiate, the press stands 17 are additional each marked with a letter a to f, the press stands arranged to the right of the transport route 17d, 17e, 17f only by their floor plans are indicated. The one illustrated by the press stand 17 Among other things, the machine frame carries in synchronism movable up and down, not shown Ram, each of which press station 11, 12, 13, 14, 15 one is assigned to each. Such a plunger 19 is For example, indicated in Fig. 3 for the press station 11.

As can be seen from Fig. 1, the press stations 11, 12, 13, 14, 15 each in areas of Transport route T arranged, in which no press stands 17 stand. For example. is the press station 11 between the press stands 17a, 17b, 17d, 17e arranged while the press stations 12, 13 between the press stands 17b, 17c, 17e, 17f are arranged.

The press station 11 has a sliding table 21 on, the stationary and to accommodate a below of the plunger 19 arranged lower tool 22 is. On the towards the lower tool 22 and from this moving plunger 19 is an upper tool 23 hung. Coupling means 25 are used for this purpose, if necessary are solvable.

In a corresponding manner, the lower tools are the Press stations 12, 13 on a common sliding table 31 and the lower tools of the press stations 14, 15 a sliding table 32 arranged (Fig. 1). The sliding tables 21, 31, 32 allow a lateral extension the press area, for example with the sliding table connected lower tool 22 and the one placed thereon To be able to replace the upper tool 23.

For transporting workpieces along the transport direction T through all press stations 11, 12, 13, 14, 15, a transfer device 35 is provided, which as Triaxial transfer is formed. The transfer facility a pair points to each other near the stand entire length of the multi-station press 1 extending Transport rails 41, 42, which are parallel to the transport direction T are arranged. The transport rails 41, 42 are arranged parallel to one another and via a Drive device 45 both in the direction of transport T matching X direction as well as in the vertically and transversely to the transport direction T. For ease of reference, the vertical is as the Y direction and the transverse direction is referred to as the Z direction. The transport device 45 contains for the transport rails 41, 42 one end with the transport rail 41, 42 connected linear drive 47, which can be controlled separately is and the transport rails, regardless of their Stroke position or their distance from each other, a longitudinal movement can give in and against the X direction.

The transport device 45 also include Drive units 49a, 49b, with the transport rails 41, 42 are connected via linear guides. The Drive units 49a, 49b are so-called lock boxes trained and adjust the transport rails 41, 42 in their distance from each other (Z direction) and in their Height (Y direction). The lock boxes 49a, 49b are in the Stand area arranged where there are no sliding tables anyway are provided. There are clipboard positions above the lock boxes intended for the workpieces. this applies also for the space between the press stations 11 and 12, a workpiece storage position is also provided here.

The transport rails 41, 42 are with carrier rails 51 releasably connected with itself from the transport rail 41, 42 away grippers 53 are provided. The Grippers 53 extend essentially along the Z direction and can be done by a specific lateral movement of the respective transport rail 41, 42 with that on the respective lower tool, for example the lower tool 22 (FIG. 3), workpiece lying in and out of engagement become.

Because of the workpiece storage positions between the Sliding tables exceed the number of support rails 51 on the transport rail 41 the number of press stations 11, 12, 13, 14, 15. The same applies to the transport rail 42. The total length of the support rails 51 thus exceeds the width of the existing between the uprights 71a, 17b, 17c Passageways.

The carrier rails 51, one of which is shown in FIG. 2 exemplified are flat on the Transport rails 41, 42 lying, stiffened carrier bodies. The carrier rail 51 lies with its flat underside 55 on the top of the support rail 41 and engages with their side edges 56, 57 the flanks of the Transport rail 41. The side edges 56, 57 at least carry an inner groove 59, 60 into each end corresponding, firmly connected to the transport rail 41 Web 61 can intervene. On her other face is the carrier rail 51 with a locking device 63 provided that the support rail 51 by means of a Locking bolt 64 fixed on the transport rail 41 locked.

On its side remote from the grippers 53 the carrier rail 51 with positive couplings 65, 66 provided with a on the respective sliding table, For example, the sliding table 22 provided receiving device 69 can optionally be coupled.

Each sliding table is on both sides with such a recording device 69 provided, because of the symmetry of the multi-station press 1 to a along and vertically extending plane of symmetry 70 in FIG. 3 only which, seen against the direction of transport T, on the right lying side of the press station 11 is shown. The Receiving device 69 has two parallel spacings mutually arranged pivoting levers 72a, 72b which by means of a pneumatic swivel device 73 synchronously to each other in a first storage position shown in FIG. 3 and in a second, shown in Fig. 4, Recording position can be pivoted. The swivel levers For this purpose, 72a, 72b are mounted in a curve guide 74.

The curve guide 74 has 72 for each pivot lever a guide groove 74a in which two pins 74b, 74c to run. The guide groove is in a straight, extending outward and into a circular arc Section divided. This leads the Swivel lever 72 a combined lift-swivel or Swivel lowering movement.

The receiving device formed by the pivot levers 72a, 72b 69 has two in the working position one above the other arranged receiving points for support rails 51 on, by corresponding to the couplings 65, 66 of the Carrier rails 51 matching, complementary couplings 75, 76 are formed. The carrier rail 51 is with their Couplings 65, 66 can be connected to the receiving device 69, by their couplings 65, 66 in the complementary Couplings 75, 76 hooked in and positively is connected to them.

The tool and gripper change is so far described multi-station press 1 as follows carried out:

In a first step, shown in FIG the plunger 19 to its uppermost position driven and the transport rail 41 is set so that a first, on the receiving device 69 of the sliding table 21 support rail 51 to be deposited in a defined Starting position is. The carrier rail is in this 51 in the press station 11.

In a second one, shown separately in FIG. 4 Step the pivot levers 72a, 72b from their horizontal position transferred to a vertical position in which the complementary couplings 75, 76 provided on them in the area of the couplings 65, 66 of the carrier rail 51 come. The couplings 65, 66 are at a short distance from the couplings 75, 76, i.e. slightly higher than this.

By a short outward and lowering movement of the Transport rail 41 are in the negative Z and Y directions the couplings 65, 66; 75, 76 engaged with each other, whereby the carrier rail 51 with the receiving device 69 is connected. The carrier rail goes from the position shown in Fig. 4 to the position 5 over.

After loosening the locking bolt shown in Fig. 2 64, the transport rail 41 performs a short longitudinal movement in the X direction, whereby the web 61 from the Grooves 59, 60 comes out and the support rail 51 is released becomes.

Then the transport rail 41 is removed from its in Fig. 5 position as shown in Fig. 6 by a thick solid arrow is shown, lowered and one complete, by the distance between two consecutive Press stations 12, 13 defined stroke width S in Move the transport direction T (X direction) until the carrier rail 51 just below that already with the receiving device 69 connected upper support rail 51 in Area of the press station 11 is. After that, how it performs is indicated in Fig. 7, the transport rail 41 a coupling movement indicated by an arrow 80, through which the lower support rail 51 is positively connected to the Recording device 69 is coupled. With a short, directed against the transport direction T and by a Arrow 81 is illustrated as the release move Fig. 2 is indicated, a separation of the transport rail 41 brought about by the carrier rail 51. That state is in Fig. 8 looking in the opposite direction of transport T illustrates.

The storage of the carrier rails 51 of the transport rail 42 at corresponding reception facilities takes place in accordingly simultaneously and synchronously.

After separation of the transport rails 41, 42 from the Carrier rail 51 is the receiving device 69 in the in Fig. 9 transferred memory position by the Pneumatic device 73 actuated and the pivot levers 72a, 72b in the curve guide 74 are moved so that the two carrier rails received by the receiving device 69 51 parallel to each other in a horizontal plane lie, the grippers 53 from the tool area are swung out. Then the upper tool 23 by lowering the plunger 19 onto the lower tool 22 hung up and the coupling means 25 is released so that the upper tool 23 is separated from the plunger 19. In a further step both the plunger 19 and also move the transport rail 41 to an upper position, 10, after which the sliding table 21st with the lower tool 22, the upper tool 23 and the in the support rails 51 accommodated in the receiving device 69 be moved out of the side of the press station can, as indicated schematically in Fig. 11.

Due to the narrow spatial arrangement of the support rails 51 protrude even though they are in operation span a wide area and especially the storage positions reach in the stand area, not over the Sliding table 21 and fit easily between the press stands 17a, 17b indicated in FIG. 1 by.

Should the press station in question be shared with others Provide tools and set them up for other workpieces Gripping means are loaded, the above Go through steps in reverse order. Fitting the transport rails with carrier rails as well as the removal of the same is done alone by moving the transport rails after the pickup device from their storage position to the recording position is transferred.

With a multi-station press 1 there is a three-axis transfer provided with two transport rails 41, 42 on which support rails 51 are placed. The support rails 51 carry grippers 53 for the workpieces. When changing tools the carrier rails 51 on corresponding Receiving devices 69 of the sliding table 21 are offset. For this purpose, the transport rail 41 is first moved so that a first carrier rail 51 connected to it on the Receiving device 69 sets. Then the transport rail 41 separated from the support rail 51 and so moved that she had a second one, still connected to her Carrier rail 51 leads to the receiving device 69. The receiving device 69 is designed so that it second carrier rail 51 in the immediate vicinity the first support rail 51 receives, both of them Carrier rails 51 overlap and ideally side to side Side are spaced from each other. The The receiving device 69 is then pivoted away to the side. The placement of the carrier rails 51 on the receiving device 69 takes place without the aid of between the transport rail 41 and the drive rail 51 acting drive means, making the construction simple and that Weight of the entire device is comparatively low can be held. This enables good dynamics of three-axis transfer with moderate drive power.
