4 Claims. (Cl. 112-2) ABSTRACT OF THE DISCLOSURE A device for winding on of workpieces arriving from a sewing installation and attached to one another by thread chains, which makes it possible to receive a great number of workpieces withdrawn from a sewing installation in an orderly manner and without the danger of entanglement, so that the workpieces may be separated from one another with a small expenditure of time when the sewing machine is inoperative.
The invention relates to a device for winding on workpieces connected with one another by thread chains, which arrive from a sewing installation.
Installations for catching workpieces connected by threads and arriving from a sewing machine are known. They consists chiefly of catching installations; as for example in German utility Patent 1,901,287, in the form of a bag secured on the ejection side of the sewing machine or the like. These simple installations are subject to a disadvantage in that the garland-like succeeding workpieces may readily be tangled with one another, thereby requiring disentanglement, resulting in a considerable loss of time.
There are fiurther known devices, such as disclosed in German Patent No. 623,607, in which workpieces arriving from a series connected machine are moved by means of a drive, e.g. an endless chain, from a receiving station in which the workpieces slide over a carrier element in dependence on the operation of the series connected machine, whereby the picked up workpiece is suspended on both sides of the carrier elements.
German Patent 1,162,176 further discloses a device, in which the carrier element for taking off of sewn workpieces behind a stacking device, is displaceable from a low position in which the sewn workpieces slide over it, to an upper end position and finally into the lower position.
Aside from the fact that only relatively long and soft workpieces may be stacked one above another with sutficient assurance and in larger numbers, these devices are not adapted for stacking of garland-like workpieces secured to one another by thread chains.
The object of the invention is to overcome these shortcomings inknown devices, which arise during the stacking or removal of particularly small workpieces secured to one another by a thread chain.
The problem. of the invention is to provide a relatively simple device for winding on of workpieces arriving from a sewing installation and attached to one another by thread chains, which makes it possible to receive a great number of workpieces withdrawn from a sewing installation in an orderly manner and without the' danger of entanglement, so that said workpieces may be separated from one another with a small expenditure of time when the sewing machine is inoperative.
According to the invention this problem is substantially solved by means of a rotatable member, controlled by the work cycle of the sewing installation, with bars 3,413,942 Patented Dec. 3, 1968 secured in ray-like fashion about its periphery for receiving the connected workpieces.
To accommodate various workpiece sizes, there are provided, on the ray-like bars, displaceably secured vertical rods. The rotatable member is driven by a friction wheel drive motor, which is switched on by the sewing installation and is switched off by suitably actuated cams secured to each of the bars, after a workpiece has been picked up.
An embodiment example of the invention is shown in the drawing, in which:
FIG. 1 is a spooling device and a sewing installation connected in series therewith, shown in plan view;
FIG. 2 is a side view of the spooling device, viewed in the direction of arrow A of FIG. 1; and
FIG. 3 is a partial section on line III-III of FIG. 1.
A rotatable member 3 is mounted on the column 2 in a column support 1 (FIGS. 2 and 3). This member comprises substantially a circular plate 4 of Wood or the like, a casing 5, a flange 7 secured to plate 4 by screws 6, and ray-shaped bars 8 pressed into the plate 4. The flange 7 and the plate 4 are provided with a bore 9 for rotatable mounting on column 2. A collar 10 is secured on the column 2 for the axial mounting of the rotatable member 3. Vertical rods 11 are displaceably secured on the bars 8 by means of clamping screws 12.
A motor 15, with its flanged drive 16, is swingably secured about the rotating point 14 to an arm 13 secured to the column 2. The drive roller 18 mounted on the drive shaft is pressed against the forward face 19 of flange 7 by means of spring 17.
This automatic sewing device 23 is of known construction. It comprises substantially a rotatable table 25, periodically actuated by a motor 24, and a workpiece and pattern holder 26 secured thereto and a sewing machine 29 mounted displaceably on the support 27 on link arms 28.
The sewing machine is automatically guided along the patterns by means of continuously driven magnetic rollers, whereby the workpiece 30 held in the workpiece and pattern holder 26 obtains a seam corresponding to the pattern.
The operation of the series connected sewing device may be described as follows:
The workpiece inserted in the holder 26 at the feed station is led clockwise at intervals to the sewing machine 29, and is by-passed by the latter for forming a seam, whereupon the holder 26 is swung, by the motor 24, into the position shown by 26' in FIG. 1 at sewing machine 29 following the connecting pattern .32, so that it may sew the next workpiece 30 which is likewise swung with the holder 26 towards the sewing machine 29 further following the connecting pattern 32. The workpieces 30 are suspended in a garland-like fashion by means of thread chain 33.
The beginning 33' of the thread chain 33 is secured to one of the bars 8 of the rotatable member 3. At each periodic partial rotation of the rotatable table 25, with the holders 26, the drive motor 15 (FIG. 3) for the rotatable member 3 is switched on by a contact (not shown), said member being displaced against the rotational direction of the rotary table 25 to such an extent that the motor 15 comes to a stop due to the switch 21 actuated by the earns 20. Thus the workpiece 30 is now disposed bet-ween the bars 8, being suspended on both thread chains 33 at the casing 5 of the rotatable member 3, whereby the thread chains 33 are imposed on the bars 8. The rotatable member 3 is thereby wound with a great number of workpieces 30, whereupon it may be lifted from the pedestal 2 for severing the workpieces from one another by means of scissors.
It is possible to preset the device, by means of the displaceable and securable rods 11 on bars 8, in such a manner that the workpieces 30 when being wound are always disposed in the space between a pair of adjacent bars 8.
With an equal angular spacing of the rotatable table 25 and the rotary member 3 it is also possible to employ the device according to the invention so that with an uniform loading of the sewing installation with workpieces of various designs, these may be sorted when removing from the spooling device.
The device according to the invention may also be employed for sewing installations other than described herein.
I claim:
1. Device for winding on of workpieces connected to one another by thread chains, comprising, in combination, a sewing machine, a pedestal adjacent said sewing machine, an annular member on said rotatable pedestal in a horizontal plane, a plurality of spaced, radially extending horizontal bars secured to the peripheral edge of said annular member for receiving the workpieces arriving from the machine, and motive means for intermittently rotating said member.
2. Device according to claim 1, further provided with vertically upwardly extending rods adjustably secured to said bars for accommodating workpieces of various dimensions.
3. Device according to claim 1, wherein said motive means comprises -a motor provided with a friction wheel engageable with said rotatable member, said motor being electrically connected with said machine, switch means for said motor, and cam means secured to each of said bars for actuating said switch means at predetermined intervals.
4. Device according to claim 1, wherein said annular member is detachable from said edestal.
