BRIEF DESCRIPTION OF USEFUL MODEL

The purpose of this utility model is to create a new and improved feed device and structure for manipulating plate blanks.

The feed device according to the present utility model is characterized by the features of the restrictive part of the first independent claim.

The construction according to the present utility model is characterized by the features of the restrictive part of the second independent claim.

The idea of the proposed solution is that the feed device comprises a feed beam that is movable relative to the feed table. The feed beam has lifting elements for moving the plate blanks vertically. Further, the feed beam is provided with one or more pushing elements for horizontal movement of the plate blanks on the feed table.

The positive effect of the proposed solution lies in the fact that the feed beam integrated in the feed device can be used in various ways to raise and lower, move and feed plate blanks in sheet metal processing equipment. When using one device instead of many separate devices, the feed machine is easier to control than several separate devices. In addition, the structure may be simpler, easier to manufacture, and less expensive.

The idea of one option is that at sites at both ends of the feed beam there are lifting devices for moving the feed beam vertically. In this case, the lifting elements on the feed beam can be stationary in the vertical direction relative to the feed beam. Alternatively, both the feed beam and the lifting elements can be adapted to move in the vertical direction.

One idea is that one end of the feed beam can be raised and lowered.

The idea of one option is that between the feed beam and the supports at its end there are horizontal rotary axes that allow you to tilt the feed beam in the vertical direction.

The idea of one embodiment is that the feed beam comprises at least one hydraulic cylinder for vertically moving the feed beam.

The idea of one option is that the lifting elements on the selling beam are made with the possibility of vertical movement relative to the feeding beam. This allows the feed beam not to move in the vertical direction at all, but the required lifting movement can be performed by moving only the lifting elements. On the other hand, it is possible to create a vertical movement of both the feed beam and the lifting elements.

The idea of one embodiment is that each lifting member on the feed beam can individually move relative to the feed beam. In this case, each lifting element has its own drive to create vertical movement. The drive may be a high pressure cylinder, such as a pneumatic or hydraulic cylinder.

The idea of one option is that the feed beam rests part of both of its ends on the feed carriage. The feed carriages can be moved along the rails using moving devices. The driving device may be, for example, an electric motor or a motor operating on a pressure medium. Further, the feed carriages can move independently of each other, so that the feed beam can be brought into an angular position relative to the feed table. Thus, the feed beam is suitable for feeding such plate blanks in which the trailing edge is beveled.

The idea of one option is that between the feed beam and the feed carriages there are pivot axes that allow horizontal rotation of the feed beam in response to different movements of the feed carriages.

The idea of one embodiment is that the leading edge of the feed beam is equipped with guides in the longitudinal direction of the feed beam. The rails support two or more pushing elements so that the pushing elements are able to move, supported by the rails, in the longitudinal direction of the feed beam. Thus, the pushing elements can be positioned in suitable places in accordance with the length of the workpiece, which is manipulated. Alternatively, instead of the leading edge, the guides may be mounted, for example, on the upper surface of the feed beam.

The idea of one embodiment is that at the front edge of the feed beam there is at least one pushing member that can be infinitely moved in the longitudinal direction of the feed beam using a moving device. One or more pushing members may be supported in rails on the leading edge of the feed beam.

The idea of one embodiment is that one or more of the pushing member on the feed beam is vertically movable relative to the feed beam.

The idea of one embodiment is that the pushing member is a straight plate member having a planar vertical pushing surface.

The idea of one option is that the operation of the feed device is related to the operation of the sheet metal processing machine. In this case, the control devices of the feeding device and the sheet metal processing machines can communicate with each other, so that control information and control commands can be transmitted between them. The control device of the feeding device can be configured to control the operation of the feeding device in response to control information received from the control device of the sheet metal processing machine, whereby the operation of the feeding device can be adjusted in accordance with the operating cycle of the sheet metal processing machine. The control device of the feed device can be configured to automatically control the duty cycle of the feed device.

The idea of one option is that the sheet metal processing machine is a friction press. The friction press can be used to stamp bends in a metal sheet using appropriate tools.

The idea of one option is that the sheet metal processing machine is a die cutting press.

The idea of one option is that the solution described in this patent application is used to manipulate metal plate blanks. Sheet metal may be steel, stainless steel, aluminum, or other metal material.

The idea of one option is that the lifting elements are cup suction cups, so that the plate blank can be lifted, capturing its flat upper surface. To activate the lifting force, a vacuum can be created in the cup suction cup.

The idea of one option is that the lifting elements are magnets, so that the plate blank can be lifted, capturing its flat upper surface. The magnet can be activated by applying electric current to it.

The idea of one option is that the upper surface of the feed table has a plurality of rolling elements, with the support of which the plate blank can be moved. Rolling elements can be, for example, balls.

The idea of one option is that the feed table is one uniform elongated table located transverse to the rails.

The idea of one option is that the feed table contains two or more parts of the table, which are located side by side and between which there are gaps.

The idea of one option is that the feed beam is made to move in a plane that is located vertically higher than the upper level of the feed table. Between the feed carriages mounted on the rails and the feed beam, a vertical arm can be installed by which the vertical position of the feed beam relative to the height of the feed table can be determined. In addition, the guides can be positioned at the required height by means of supporting elements between the floor and the guides.

The idea of one embodiment is that the feed beam is a box-shaped structure formed from a sheet and has a substantially rectangular section.

The idea of one embodiment is that the connection between the feed beam and the pivot axis contains movement elements that allow the feed beam to move in the longitudinal direction of the feed beam between the feed beam and the pivot axis when the feed beam is rotated in an angular position relative to the guides. When the feed beam is oriented perpendicular to the guides, the distance between the feed carriages is the smallest. This distance, however, increases if the carriages move differently and the feed beam is rotated into an angular position. Using elements for movement, such a change in the distance between the connection points can be compensated.

The idea of one option is that between the feed beam and the feed carriage there is a rotary axis having a tubular structure. The pivot axis may contain two or more tubular parts of different sizes, which are partially located one in another so as to form a telescopic structure. In this case, the length of the pivot axis may change if the vertical position of the feed beam changes.

The idea of one option is that the feed beam is made with the possibility of vertical movement using hydraulic cylinders to parts of its ends. The rotary axes can be tubular, so that the hydraulic cylinders can be inside the tubular rotary axes.

The idea of one option is that the feed beam can be brought to the loading station, which is located on the first edge of the horizontal path of the feed beam. The loading station and the feed table are thus at opposite ends. At a loading station, a stack of sheets or a separate plate blank may be placed on a floor surface or an appropriate transport platform. The feed beam can be brought into position above the loading station, after which its lifting elements can be brought into contact with the upper surface of the sheet blank below. After that, the gripping force of the lifting element is activated and the sheet blank is lifted.

DETAILED DESCRIPTION OF SOME OPTIONS

Figure 1 shows the feeding device 1, which contains the feeding table 2, which may be one piece or a plurality of table parts 3, which together form the feeding table 3. There may be gaps between adjacent parts 3 of the table. The upper surface of the feeding table 2 may have rolling elements 4, which facilitate the movement of the workpiece subjected to manipulation. The feed table 2 can be located in the direction of and next to the sheet metal processing machine so that the part to be manipulated can be moved with support on the feed table 2 for processing by this machine. The position of the sheet metal processing machine in the drawing is roughly shown by line 5. Further, the feeding device 1 comprises guides 6a, 6b extending transversely to the feeding table 2 and on which an elongated feeding beam 7 is supported. The feeding beam 7 may be a box-like structure extending transverse to the honey guides 6a, 6b. On the guides 6a, 6b, feeding carriages 8 can be installed, by means of which the feeding beam 7 can move in the horizontal direction N. There is a loading station 9 at the first end of the guides 6a, 6b, and the feeding table 2 at the other end, and the feeding beam 7 can move between them in accordance with the working cycle of the feeding device 1. At the loading station 9, you can bring a stack of 10 sheets, consisting of many plate blanks. The feed beam 7 can be moved to a position above the stack, as shown in FIG. The feed beam 7 has a plurality of lifting elements 11, which are placed on the upper surface of the upper plate blank 12 in the stack of blanks 10, after which the lifting elements 11 are activated to create an exciting force. After the plate blank 12 is lifted in the vertical direction V, the feed beam 7 can move the plate blank 12 horizontally (H) to the feed table 2.

The operation of the feeding device 1 can be controlled by means consisting of at least a first control device CD1. The first control device CD1 of the feeding device 1 may be in contact with at least a second control device CD2 of the sheet metal processing machine 5. In this case, the first control device CD1 of the feeding device 1 can control the operation of the feeding device 1 based on the control information received from the second control device CD2 of the sheet metal processing machine 5. The feeding device 1 can be controlled automatically in accordance with the duty cycle of the sheet metal processing machine 5.

Figure 1 further shows that the feed beam 7 is equipped with one or more push elements 13. The push element 13 may be a plate part, the plane of which extends in the vertical direction. There may be two or three pushing elements 13 or, if necessary, even more. Using the pushing elements 13, the plate blank 12 located on the feed table 2 can be pushed towards the sheet metal processing machine 5, as will be shown in FIG. 3. The push members 13 are moved in the feed direction by moving the feed beam 7. At the leading edge 7a of the feed beam 7, that is, at the edge facing toward the feed table 2, there may be guides 14 in the longitudinal direction of the feed beam 7 that support the push members 13. In this case, the position of the pushing elements 13 can be changed in the longitudinal direction L of the feed beam 7. The pushing elements 7 can move steplessly. The feed beam 7 may contain one or more actuators, through which you can change the position of the pushing elements 13.

Figure 2 shows the situation when the feed beam 7 has moved to a position above the feed table 2. In this case, the plate blank 12 can be lowered onto the upper surface of the feed table 2 and the exciting force of the lifting elements 11 is removed. After that, the feed beam 7 is retracted, so so that the pushing element 13 can be brought to the trailing edge of the plate blank 12.

The pushing elements 13 can be led to the trailing edge of the plate blank 12 which has been lifted onto the feeding table 2, that is, to the edge on the side of the loading station 9, by the following alternative methods: the height of the feeding table 2 can be changed, the pushing elements 13 can be moved vertically down , or you can move the feed beam 7 vertically down.

In Fig. 3, the plate blank is pushed out in the feed direction using the pushing elements 13. The drawing shows that the ends of the feed beam 7 can move along the guides to an unequal distance, as a result of which the feed beam 7 can occupy an angular position relative to the feed table 2. In this in this case, the pushing elements 13 of the feed beam 7 can also be brought to the trailing edge of the plate blank 12 having a beveled edge. Between the feed beam 7 and the feed carriages 8, there may be pivoting axles 15 that allow the feed beam 7 to rotate in the horizontal direction H when the feed carriages 8 move along the guides 6a, 6b in different directions or at different distances.

Figure 4 shows a fragment of the end of the feed beam 7. The feed beam 7 can rotate relative to the vertical axis 16. The rotary axis 15 can have a tubular structure, so that it can have a first tubular part 17 of a larger diameter and a second tubular part 18 of a smaller diameter. The tubular parts 17, 18 are partially arranged in one another so as to form a telescopic structure. In this case, the length of the pivot axis 15 changes when the vertical position of the feed beam 7 is changed by the lifting device 19. The lifting device 19 may be, for example, a hydraulic cylinder, which may be located inside the tubular pivot axis 15. The first tubular part 17 is supported by the feed carriage 8.

Figure 5 shows in a simplified form the feed beam 7 and its rotation into an angular position. The angular position in the drawing is shown by the dashed line 7a. Since the distance between the rotary axes 15 in the angular position 7a is greater than in the perpendicular position, there are elements 20 for moving the feed beam 7 relative to the rotary axes 15, which allow the movement A in the longitudinal direction of the feed beam 7. The rotation of the feed beam 7 can be performed by moving the rotary axes 15 in opposite directions H1, H2 by the feed carriages, or by moving only one end of the feed beam 7.

Figure 6 shows the feed beam 7 and alternative lifting elements 11a, 11b mounted on it. The lifting member may be a cup suction cup 11a that can be moved relative to the feeding beam 7 by the drive 21. Alternatively, the lifting member may be a magnet 11b. On a common frame 22, which can be moved by the drive 21, two or more lifting elements can be mounted. The feed beam 7 can be stationary in the vertical direction V or, alternatively, it can be moved by lifting devices 19. If necessary, the ends of the feed beam 7 can move in the vertical direction independently of each other, so there can be a horizontal rotary axis 23 between the feed beam 7 and the rotary axis 15.

7 shows a machine 5 for processing sheet metal, in this case, a vertical friction press 24, which contains a frame having at least ends 25 and 26 that can rest on the floor. Between the ends 25, 26 is the upper beam 27 and the lower beam 28. The upper beam 27 can be moved in the vertical direction with the help of the power elements 29 and 30 to the lower beam during edge processing. Between the upper beam 27 and the lower beam 28 there is a gap 31 into which the plate blank 14 can be inserted. Opposite longitudinal edges of the beams 27, 28 have abutment surfaces 32 to which it is fashionable to attach an edging tool. In such a friction press 24, for example, it is possible to feed the workpiece to be pressed using a feeding device described in this application. The control device CD2 of the sheet metal processing machine can be connected to the control device of the feed device, whereby the feed device can be controlled in accordance with the edge processing duty cycles.

In some cases, the features disclosed in this application may be applied individually, independently of other features. On the other hand, if necessary, the features disclosed in this application can be combined to obtain other combinations.

The drawings and the corresponding description are intended only to illustrate the idea of a utility model. The details of a utility model may vary within the scope of the utility model formula.
