DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention concerns a device for conveying items of household linen from a first processing machine to a subsequent processing machine of a textile or laundry processing line.
BACKGROUND ART
The device for conveying items of household linen is preferably employed where a visual control of the items of household linen must be carried out between two processing machines. This could be the case at the exit of a sewing robot, where, for example, linens, in particular fitted sheets, are to be examined as to quality before they are transferred to a subsequent folding robot.
Until now, continuing with the same example, the sheets emitted from the sewing robot fell to the floor where a disorderly pile was formed. One sheet after another was then picked up by two operating personnel, spread out, and checked. When it was considered to be in order, it was placed on an input conveyor of the folding robot which followed the sewing robot. With the rejected goods, a further disorderly pile of sheets was formed. These tasks are time-consuming, tedious and tiring. When carried out over a long period of time, the quality of control suffers.
DISCLOSURE OF THE INVENTION
It is the object of the present invention to offer an improvement in this respect. With a device for conveying items of household linen according to the invention not only should there be less manual work, but the quality of control should be improved and guaranteed over a longer period of time.
This object is fulfilled with the features of the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will now be explained more closely, with the aid of an embodiment, with reference to the drawings in which
FIG. 1 is a side view of the device for conveying items of household linen according to the invention, arranged in a processing line,
FIG. 2 is a frontal view of the device for conveying items of household linen according to FIG. 1,
FIG. 3 is an enlargement of the section marked A in FIG. 2, with a holding element and a first control means, and
FIG. 4 is a side view of the holding element and of the first control means according to FIG. 3.
BEST MODE FOR CARRYING OUT THE INVENTION
In FIG. 1 and 2 the device for conveying items of household linen according to the invention is presented in a side view. FIG. 1 shows moreover the arrangement of the device for conveying items of household linen 1 in a processing line. A first processing machine, for example a sewing robot, is designated with 2. This robot has an output conveyor 4 which outputs bedlinen or clothing articles 7. A second processing machine 3, for example a folding robot, is disposed after the sewing robot at a distance. This machine has an input conveyor 5. Positioned between said two processing machines 2, 3 is a device for conveying items of household linen 1 according to the invention. This device has the task of conveying processed items of household linen 7, which leave the sewing robot 2, in the direction of the folding robot 3. Achieved thereby should be that each item of household linen is brought during conveyance into a position suitable for a visual quality control. The device for conveying items of household linen 1 comprises a frame 17, consisting of four vertical supports 18, which, forming a square, are disposed spaced apart from each other. On their ends turned away from the floor, two each of vertical supports 18 are connected crosswise to the conveying direction with horizontal supports 19. Longitudinally to the conveying direction of the items of household linen, two each of adjacent vertical supports 18 are fixed together with one connecting plate 20, 20' each. An electric motor 21 is disposed on one of these connecting plates 20'. The rpm of the motor can be set or varied. By means of a chain 22 the motor drives a drive wheel 9', which, via a shaft, is connected to a further drive wheel 9 disposed on the connecting plate 20 opposite the motor. Disposed on each of the connecting plates, moreover, is one extension arm 12, 13 or 12',
