DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an arrangement of apparatus intended for transporting objects along a given movement path and comprising a stand structure, a slide assembly carried by the stand structure, and a grippingdevice attachment means connected to the slide assembly, said gripping device being intended to hold the object during its movement along said path.
When pressing sheet-metal components in a press line, for instance sheet-metal components for the automobile industry, various kinds of handling equipment are used for removing the components from a press and inserting said components in the next press in said press line. In this respect, it is important that the components are lifted vertically from the tool of the first press and then transported horizontally and finally deposited, either directly into the tool of the next press or onto a conveyor arrangement, which transports the components to an infeed station located in front of the next press, where a further transport arrangement introduces the components into the press tool. When feeding and removing the sheet-metal components into and from the press tools respectively, it is important that movement of the components relative to the press tool is purely vertical, so that the component will be correctly positioned on the tool and so that the tool will not be damaged by erroneous positioning of the sheet-metal components. Furthermore, the components should be moved into and out of the presses horizontally, since the space in the presses is restricted in the vertical direction.
Modern presses also operate at high speeds, and consequently the arrangement provided for transferring the components between the presses must work equally as quickly, in order to enable the full capacity of the presses to be utilized. The transfer arrangement must therefore work swiftly, in order to cooperate with modern presses.
The object of the present invention is to provide a transfer arrangement which will afford the requisite movement pattern and which is able to operate at high speed and capable of moving at high acceleration, so that each working operation can be carried out in a relatively short time period. This object is achieved in accordance with the invention with an arrangement of the kind described in the introduction and having the characteristic features set forth below.
The inventive apparatus is capable of operating at the high accelerations and speeds required to enable each working operation to be carried out in relatively short time periods, so that the arrangement is able to cooperate with modern presses operating at high capacities.
The invention will now be described in more detail with reference to the accompanying drawings, which illustrate an exemplifying embodiment of the inventive arrangement and in which
FIG. 1 is a front view of the arrangement;
FIG. 2 is a side view of the arrangement illustrated in
FIG. 1; and
FIG. 3 is a sectional view taken on the line III--III in FIG. 1.
The inventive arrangement illustrated in the drawings includes a stand 1, which in the case of the illustrated embodiment is intended to be mounted, e.g. on a press (not shown in the drawing). The stand 1 is provided with guides 2 or rails which are located vertically one above the other and which extend horizontally along the longitudinal edges of the stand 1.
The inventive arrangement further comprises an elongated carrier 4 on which carriages 3 are mounted for movement along the guides or rails 2, such as to enable the elongated carrier 4 to be moved along the guides 2 on the stand 1, with the aid of the carriages 3. This movement of the elongated carrier 4 is accomplished by means of a drive motor 5 connected to a gear 6, which in turn carries a drive roller 7. A toothed belt 9 extends over the drive roller 7 and over a guide roller or pulley 8 located at the opposite end of the stand 1, said belt 9 being attached to an attachment 10 on the elongated carrier 4.
The elongated carrier 4 is provided with guides 11 which extend perpendicular to the guides 2 on
