Abstract

A transfer system for press lines in a hall structure is proposed, the transfer system being provided at the beginning and/or at the end and/or between individual presses of a press line for transporting workpieces between the individual presses and/or for inserting or removing them from the individual presses and being formed as functional unit, having at least one transfer device, and a traverse arranged on the transfer device, and a chassis with at least one movement device for the horizontal or vertical movement of the transfer system. A system of press line transfer is also proposed.

Description

The automation of press systems, especially of individual presses connected in series, to press lines or press lines is carried out by robots or various types of transfer devices such as linear feeders or articulated arm systems, or also by combined transfer systems. All of these devices transport a workpiece from press to press or station to station by means of grippers or vacuum suction cups attached to a traverse. These grippers or vacuum suction cups are arranged in a type of frame or rack as a so-called tooling or suction spider or workpiece gripping device and are exchanged during a tool change. The traverse is transverse to the throughput direction of the workpieces. In order to produce different workpieces, different tools are available that have to be changed.

These massive tools can be moved out of the press using mobile tables for tool changes. The workpiece-specific tooling or the entire transfer bar (suction bar/crossbar, traverse) can also be moved out with the mobile tables or on separate, so-called tooling change cars or change cars. The tooling changing carriages or changing carriages drive into the press gaps, i.e. between two adjacent presses.

For example, presses are linked to form a press line with a one-sided articulated system. This is a multi-section and multi-axis articulated arm transfer unit that carries a traverse with movable tooling in the middle and uses it to transport the workpieces from press to press, as shown in the EP 2 694 231 B1 disclosed. The object of this invention is to increase the flexibility of the transfer device and in particular to improve the automatic tooling change. The flexibility is made possible by the use of many driven axes. This causes high moving masses, heavily stressed joints and guides, which is maintenance-intensive and expensive.

In practice, the short downtimes of the one-sided articulated systems are bridged by the provision of complete replacement transfer systems. These can be exchanged with acceptable effort. However, the press system has to be shut down for a certain period of time for this maintenance work.

Furthermore, in the WO 2006/045 284 A1 discloses a tooling changing device with which the traverse together with the tooling is placed on a carriage and can be moved out of the press system in order to carry out a tooling change.

In the DE 10 2013 220 309 A1 discloses a system of transfer device, interchangeable traverse and changing carriage with a similar function.

These inventions solve the problem of replacing the workpiece-specific tooling fully or partially automatically during the tool change process. However, due to the large number of individual steps, a longer interruption in press operation is also possible here. In addition, there remains the problem of repairing or readjusting transfer devices that require maintenance without interrupting press operation for a longer period of time.

It is therefore an object of this invention to provide a transfer system that overcomes these disadvantages, that is to say to provide both a tooling change and maintenance of the transfer device, while keeping interruptions in press operation as short as possible.

According to the invention, this object is achieved by the features of the independent claims. Advantageous configurations are the subject matter of the dependent claims.

In the following descriptions of the figures, the same elements or functions are provided with the same reference symbols.

As already mentioned at the beginning, the automation of press systems, especially of individual presses 2 connected in series to press lines or press lines 1, takes place, as in 1 shown by robots or various transfer devices such as linear feeders or articulated arm systems. All of these devices transport a workpiece from one individual press 2 to another individual press 2 or from station to station by means of grippers or vacuum suction cups attached to a traverse 6 . These grippers or vacuum suction cups are arranged in a type of frame as so-called tooling 7, also referred to as a suction spider or workpiece gripping device, and are exchanged during a tool change. The traverse 6 is transverse to the direction of passage of the workpieces and is coupled to the transfer device 5 via one or more articulated arms 5.2.1. Different, interchangeable tools are available to produce different workpieces. The change is done with mobile tables 3, on which the (very heavy) tool is placed and then move out of the press line 1. A new tool is loaded on another traveling table 3 provided on the opposite side of the press line 1, and is moved into the press line 1 as soon as the traveling table 3 with the tool to be changed is extended.

Currently known transfer devices 5 work with very similar and proven tooling systems, i.e. the requirements for the tooling components or the entire tooling unit are very similar. The largest tooling unit must be designed in such a way that it is user-friendly, can be handled manually (usually by a single operator) in terms of size, weight, locking and unlocking and also complies with occupational health and safety guidelines.

When designing, it must also be taken into account that it must be possible to attach media such as air, oiling or similar, control currents and power currents for drives and signal currents to the tooling 7.

As also already described, workpiece-specific toolings can be exchanged fully or semi-automatically during the tool changing process, in that tooling changing carriages or changing carriages move in and out of the press line 1 . However, press line 1 can also come to a standstill for a longer period of time. In addition, there is still the problem of repairing or replacing transfer devices 5 that require maintenance set without interrupting press operation for any length of time.

Therefore, a novel transfer system 100 is provided according to the invention, which can be extended or moved horizontally or vertically out of the press line 1 . In one embodiment, this transfer system 100 has a transfer device 5, a traverse 6 and a changing device in the form of a chassis 4, on which the transfer device 5 and traverse 6 are integrated as a functional unit. In this embodiment, corresponding means, described below, are provided which make it possible to extend the transfer system 100 horizontally out of the press line 1 .

In another embodiment, no chassis is provided. In this embodiment, corresponding means, described below, are provided which make it possible to extend the transfer system 100 vertically out of the press line 1.

In addition, in all versions of the transfer system 100 a tooling 7 can be provided which is detachably fastened to the traverse 6 . The proposed transfer system 100 allows press lines 1 to be further automated, and both tooling changes and maintenance work are possible without major standstills of the individual presses 2 within the press line 1 . The proposed transfer system 100 of both main versions can be retrofitted, technically expanded, exchanged and is easy to maintain. The goal is to keep changeover times as short as possible. This includes tool change times, tooling change times or maintenance times. The aim is to achieve as high a level of functional integration as possible between the press and the transfer device, while at the same time mechanically separating these components.

According to one embodiment, the transfer systems 100 of both main versions with the associated transfer devices 5 are each moved horizontally or vertically out of the press system or press line 1 as a complete functional unit, as in 2 , 3 and 7 shown and described below. A pair of transfer systems 100 can be provided for each individual press 2, which are formed in the same way (e.g. two transfer systems 100 articulated on one side or two on two sides) or differently, as for example in 4 1, in which the top is a double-ended transfer system 100 and the bottom is a single-ended transfer system 100.

Each transfer system 100 of a first, preferred embodiment is housed in an associated movable frame, referred to as chassis 4 for short, ie attached to it or formed integrally therewith, as in 5 and 6 shown and described below.

The individual presses 2 of a press line 1 are generally isolated from vibrations independently of one another, i.e. sprung. This results in small vertical movements of the individual presses 2 relative to the hall floor 8, which must be taken into account for the type of attachment of the chassis 4 or the transfer device 5 within the press line 1 (in the operating position P1). During production, i.e. during operation of the individual presses 2, a chassis 4 or a transfer device 5 is attached to each individual press 2, e.g. its stand, via corresponding coupling points 4.1 (coupling element transfer system) and 4.2 (counter-coupling element individual press). The transfer system 100 is a coupling element 4.1 with a counter-coupling element 4.2. coupled to the single press 2, as in 1 shown on the left. In 1 on the right, the transfer system 100 is not yet coupled to the single press 2.

In one embodiment, these coupling points are 4.1; 4.2 of the single press 2 on the outlet side of the press frame, i.e. the side of the single press 2 on which the processed workpiece is passed on to the next processing stage, e.g. to the next single press 2. The removal of the workpiece from the tool area requires (in view of the restricted freedom of movement) higher accuracy than the insertion. Thus, attachment of the transfer device 5 to the press frame on the outlet side is preferable.

In a further embodiment, the coupling points 4.1; 4.2 attached independently of the press frame to an area of the hall structure, for example on the hall floor 8, as in 6 shown schematically.

There are different types of coupling points. On the one hand, coupling elements 4.1; 4.2 necessary to absorb the forces that arise from the moving masses and to fix a sufficiently repeatable position of the transfer device 5 to the individual press 2. On the other hand, coupling points are also required as supply couplings, or so-called multi-couplings 4.6, for energy, signals and media (e.g. air, oil).

In one embodiment, the chassis 4 used for the horizontal movement is advantageously designed as a closed frame. In other versions, the chassis 4 can also be designed as an open frame, that is to say with two mutually parallel vertical uprights and a crossbeam which connects the two vertical uprights de. The at least one coupling element 4.1 is advantageously provided on a vertical stand.

The chassis 4 can have an electric, pneumatic or hydraulic drive. The energy supply for the drive or drives of the chassis 4 can be carried out similarly to the mobile tables 3 via drag chains, cable drums (electric, air, oil) or wirelessly via battery operation, depending on the design of the drive. A drive can either be attached directly to the chassis 4 or provided as an external drive.

Both the wired energy supply and the multi-couplings 4.6 can be supplied both from the hall floor 8 and via the individual press 2. The drives advantageously have a communication device that can be operated by radio control or wired, e.g. via an external control panel.

The chassis 4 for the horizontal movement of the transfer system 100 have at least one rail-mounted or non-rail-mounted movement device 4.3, 4.4, which makes it possible to move the chassis 4 in the horizontal direction. For this purpose, the at least one movement device 4.3, 4.4 can be formed as part of a rail system with steel wheels or gliders 4.4 and a running rail 8.1 embedded in the hall floor 8, as in 5 implied. But it can also be used as wheels 4.4, as in 6 indicated to be formed. Since rail systems are usually already present in existing halls for press lines 1, ie running rails 8.1 embedded in the hall floor 8, retrofitting is possible here. However, the movement device 4.3, 4.4 can also be designed as an air cushion or as a roller system with a chain drive or as a combination, where appropriate.

In order to move the transfer system 100 in the vertical direction into a changing position P2, at least one (vertical) moving device 4.5 is also provided. This can be the lifting device of the transfer system 100, for example in the form of its lifting axis and an extended, vertical guide system. This makes it possible to move the transfer system 100 upwards into a changing position P2 (above the press line 1) and back into the operating position P1, i.e. into the press line 1, as in FIG 7 shown. Paths that go beyond this can be covered with the indoor crane, for example. The hall crane allows the transfer system 100 to be parked in any position for conversion or waiting on hall floor 8.

In one embodiment, it is provided that the traverse 6 is placed, e.g. by means of a crane.

However, the lifting device also makes it possible to move the transfer system 100 downwards into a changing position P2 (into the hall basement 9) and back into the operating position P1, i.e. into the press line 1, as in 7 shown. Provision can be made for this work to be carried out below the hall floor 8 in the hall basement 9 .

In addition, instead of the lifting device, an external (vertical) movement device 4.5 in the form of a crane system, for example, can be provided, which can move the transfer system 100 upwards (above the press line 1) and back into the operating position P1, i.e. into the press line 1.

A frame for vertically movable transfer systems 100 can also be provided, which is formed as an open or closed frame similar to the described chassis 4, on which the coupling elements 4.1 are provided. The transfer system 100 is fixed in or on the frame on which the (vertical) movement device 4.5 can act.

A combination of horizontal and vertical movement devices 4.3, 4.4, 4.5 can also be provided. For example, the transfer system 100 can be removed vertically from the press line 1 and the replacement transfer system 100 can move in horizontally, or vice versa.

The transfer system 100 entering the press line 1 is advantageously centered using suitable means. In order to move it out of the press line 8, the centering (and also the coupling to the individual press 2 or the hall floor 8) must first be released. For example, the transfer system 100 can be centered by means of a centering pin (not shown). The centering pin is either provided in the hall floor 8 and the transfer system 100 has a corresponding opening for insertion, or vice versa.

The process of changing transfer system 100, i.e. changing transfer system 100 from an operating position P1 to a change position P2 (fields drawn in dashed lines in 2 and 3 ), can be carried out fully or partially automatically, depending on the degree of automation of the press line 1.

In one embodiment, analogously to the mobile tables 3, which are assigned in pairs to an individual press 2 for changing tools, the transfer systems 100 are also assigned in pairs to an individual press 2, as shown in the figures.

The entire transfer system 100 can be moved out of the press line 1 horizontally by the chassis 4 in the same direction as the moving table 3, as in 2 represented by the directional arrows, or in the opposite direction, i.e. to the side that is opposite the side on which the moving table 3 is moved out, as in 3 represented by the directional arrows. A combination of both variants is also possible depending on the design of the hall logistics. In the 2 and 3 are the transfer systems 100 and moving tables 3, which are currently in the press line 1, drawn with solid lines, and drawn in dashed lines in their position after the change in the change position P2. Transfer systems 100, which serve as replacement transfer systems 100, i.e. which move into press line 1 instead of the transfer systems 100 currently used in press line 1, are shown in a changeover position P2 and are also drawn with a continuous line (for the sake of clarity only in 2 ). Likewise, mobile tables 3, which move into the press line 1 instead of the mobile tables 3 currently used in the press line 1, are drawn with a solid line.

As a rule, the tools on the moving table 3 are changed with a crane and the tooling 7 is changed manually. With a view to further automating the entire changing process, for example through the use of robots and driverless transport systems, good accessibility is becoming increasingly important. Thus the in 3 The variant shown is preferred for horizontal movement, as it ensures better accessibility.

The transfer devices 5 of the individual presses 2 can be of the same type or different in any combination depending on the requirements of the manufacturing process of the workpiece. For example, a transfer device 5.1 articulated on one side, e.g. an insertion robot, can be used for loading into the first individual press 2 and for removal from the last individual press 2, a transfer device 5.1 articulated on one side, e.g become. Each of these transfer devices 5 comprises coupling elements 4.1, which are connected to counter-coupling elements 4.2 (see Fig 1 , 2 , 5 and 6 ) can be connected and thus fasten the transfer system 100 to the individual press 2 or the hall floor 8. Energy and media can also be supplied via the multi-couplings 4.6 provided, as in 5 and 6 implied.

A pair (also referred to as an interchangeable set) of transfer devices 5 belonging to a single press 2 can consist of two different types of transfer devices 5, e.g. a transfer device 5.1 articulated on one side, as in 4 shown below, and a two-sided articulated transfer device 5.2, as in 4 shown above. This situation is conceivable if only one set of transfer devices 5 belongs to the press line 1 and later a more powerful set is retrofitted if, for example, newly developed tools or workpieces require this. Here, too, the transfer system 100 and moving table 3 can be moved in or out of the press line 1 in the same direction or in opposite directions, as in 2 and 3 shown. Alternatively, the transfer system 100 can be moved out of the press line 1 vertically.

Due to the design of the transfer system 100 as a functional unit, a complex, mechanical, automatic coupling point 67 between the transfer device 5 and the traverse 6, as is currently customary, can optionally be omitted. Only the tooling 7 needs a coupling point to the traverse 6, which serves for the mechanical coupling and also for the supply of energy and media between the traverse 6 and the tooling 7. This results in more advantageous constructions that have less mass and are cheaper.

In a further embodiment, the tooling 7 or the traverse 6 together with the tooling 7 are placed on the moving table 3 by means of the transfer device 5 and moved out of the press line 1 for the tool change. The transfer device 5 itself, ie the transfer system 100 with all the remaining components, is only moved out of the press line 1 for the purpose of maintenance or other conversion.

Moving out (horizontally or vertically) the entire transfer system 100 and moving in (horizontally or vertically) an entire transfer system 100 (replacement unit) from different sides or from above or below reduces the usual maintenance times enormously and prevents unplanned downtimes.

In addition, existing tooling systems as well as new tooling systems can be integrated.

For manual conversion or maintenance work on the individual presses 2 and especially on the tool rooms, there is good accessibility for given to the operator by moving the transfer system 100 out of the press line 2.

In one embodiment, the transfer system 100 is firmly coupled to the transfer unit 5 outside of the individual press 2 and is supplied with energy and media. Thus, the transfer system 100 can be used as a transfer simulator and for training purposes.

In order to change from one transfer system 100 to another transfer system 100, all couplings 4.1 and 4.2 and 4.6 must be released so that the transfer system 100 can move freely. It can be loosened from a centering position, e.g. raised or lifted out.
