EP0104298B1 - Device for the logistic operation of textile machines - Google Patents

Description

The invention relates to a device for logistical operation of textile machines, in particular to ensure material replenishment, maintenance and removal of finished goods in weaving machines.

Such a device is e.g. in U.S. Patent 2,994,939. This is a frame that can be moved on rollers to accommodate several warp beams, the frame being provided for interaction with parts of the weaving machine. However, this device has the disadvantage that only a narrow part of the weaving machine is accessible. In this way, only either the front or the back can be operated and, in order to change from the front to the back, the frame has to be rolled through the aisles between the machines to the other side of the weaving machine in a time-consuming manner. Furthermore, the accessibility in the middle of the weaving machine is not sufficiently guaranteed and only a limited number of operations can be carried out, since the frame has a very limited capacity. If different operations are to be carried out, time-consuming retrofitting work on the frame is required. Furthermore, due to the limited space in the aisles of the weaving room, the frame is a hindrance both for the operation of the weaving machines and for the transport of materials in and out.

DE-A-2 832 742 also describes a device for the logistical operation of textile machines, which has a support frame which can be moved over the textile machines and has at least two parallel supports, the supports being adjustable in the longitudinal direction, and at least one support having a guide arrangement for at least one element movable in its longitudinal direction for receiving working elements which can be controlled by the textile machines. However, it is by no means a matter of course for the person skilled in the art to design these carriers in such a way that they can be adjusted in the transverse direction, since the problem of setting the system to different weaving machine widths does not arise during cleaning. It is sufficient that the suction devices that can be moved with the bridge are moved to the corresponding cleaning point. The problem of displacement, however, arises when inserting or lifting warp beams etc., which have to be gripped and lifted at two different points at the same time. In contrast, moving the crane girder according to this document during operation would be a completely unnecessary measure that would make cleaning unnecessarily expensive.

DE-A-2 627 017 also belongs to the further prior art, which relates to an overground warp beam and tableware loading device with automatic horizontal control in two levels for textile companies. However, this device consists of rigidly interconnected supports and cannot be used for the purposes of the present invention.

The object of the invention is to provide a device of the type mentioned which, with a space-saving construction, enables rapid operation of all weaving machine areas, can be easily moved from a weaving machine to any other weaving machine in the weaving room and ensures all necessary operating processes without any special retrofitting.

The features according to the characterizing part of claim 1 serve to solve this task.

In this way it can be achieved that textile machine parts of different length, such as. B. warp beams, fabric trees, shafts etc., can be gripped and lifted at both ends at any time by a pair of grippers, the respective distance of which can be set as desired. The support frame can be movably guided in a conventional manner on double girders suspended in the ceiling of the weaving room. B. extend over a number of weaving machines, knitting machines, etc. The accessibility of the individual machines is not impaired by the ground clearance and it is easy to transport to and from the machine. B. of full or empty warp beams without the operation of the textile machinery is hindered. The device can easily be designed so that each of the textile machines can be detected in the machine room.

According to a particularly advantageous embodiment of the invention, the guide arrangement can have at least two guide levels. This allows a simple linear movement of several, for. B. accomplish parallel working links on rolling bodies moved by means of rotary drives.

For mutual adjustment, the carriers can be coupled to one another via working cylinders. This enables the beams to be spread or brought together in any position of the supporting frame, e.g. to adapt to different weaving machine widths.

The support frame can have at least one additional support that can be moved in the longitudinal and / or transverse direction. This allows any places in the middle of the weaving machine, e.g. Control shafts or warp thread monitors.

The working members can be pivoted and / or adjustable in length working cylinders with grippers, suction, blowing or lubricating nozzles. As a result, practically all of the necessary operations on the textile machine can be carried out without having to convert to other work members.

Telescopic hydraulic or pneumatic cylinders can be provided as working cylinders. This ensures a particularly high degree of mobility of the working members and accessibility of the textile machine.

At least two, mutually displaceable in the longitudinal direction, can be attached to the additional carrier Working cylinders can be arranged. As a result, operations can be carried out at the same time by working members arranged in pairs on several textile machine parts, such as, for. B. Lifting a warp beam while lifting the shafts.

The working cylinders can be coupled to one another via a third working cylinder. As a result, the distance between the working cylinders can be set independently of the distance between the supports of the supporting frame.

Furthermore, caliper-type grippers can be provided on the working cylinders for the purpose of clamping and / or lifting a plurality of shafts and / or warp thread monitors at the same time. This enables the shafts to be lifted reliably without high precision requirements with regard to the longitudinal position of the grippers compared to the shaft length. There is thus no need for complex optical scanners.

Finally, at least two working elements can be connected to a common drive and / or control device assigned to the support frame, this being connected via current collectors to a contact line which extends over at least two textile machines for the transmission of operating energy and / or control signals. This enables logistical operation of a number of textile machines through a central command station, e.g. through a fully automatic program control.

The invention is explained in more detail using exemplary embodiments in conjunction with the drawing below. Show it:

• 1 is a perspective view of a device according to the invention, which is movable over a series of weaving machines, and has working members with grippers for operating the warp beam, fabric beam and shafts,
• Fig. 2 is a partially schematic side view of the device of FIG. 1, according to arrow 11, which has an additional working element with suction, blowing or lubricating nozzles, and
• Fig. 3 shows another embodiment of the device with working members for the introduction of a weft bobbin frame and replacement of the weft bobbins on a weaving machine.

Two weaving machines 10, 12 (FIGS. 1, 2) each have two side cheeks 14, 16, a weft assembly 24 having a weft bobbin 18, a thread storage device 20 and a thread tensioner 22, as well as shafts 28 moved by a dobby 26, the shafts being moved by one Warp beam 29 unwound warp threads 30 over a deflecting beam 32, through which shafts 28 and through a reed 34 are guided and the finished goods 36 are wound up over a chest beam 37, a goods take-off roller 38 and a deflecting beam 39 on a goods beam 40.

A support frame 42 movable over the weaving machine 10 has two parallel supports 44, 46, which have a double flange guide, each consisting of an upper flange 45 and a lower flange 47, and two in the ceiling by means of roller brackets 48, 50, 52, 54 of the weaving room in the longitudinal direction of the loom row arranged flange carriers 56, 58 are suspended and coupled to one another via telescopic working cylinders 60, 62. An electric traction motor 64 serves to move the support frame 42 along the flange supports 56, 58, and its power line 66 is connected to a drive and / or control device 68, which in turn connects the wires 74, 76 to a central one via two current collectors 70, 72 Signal generator 78 connected overhead line 80 are connected.

The drive and / or control device 68 rests on an additional support 82 which extends transversely to the supports 44, 46 and which, like the supports 44, 46, has an upper flange 84 and a lower flange 86 as a guide. The additional carrier 82 is supported on its upper flange 84 by means of roller brackets 85, 87 on trolleys 88, 90, which in turn are supported by roller brackets 92, 94, 96, 98 on the upper flange 45 of the carriers 44, 46, the flanges thus guiding surfaces form. The traction motor 100 can shift the additional carrier 82 in its longitudinal direction according to arrow 101, while the traction motors 102, 104 ensure a displacement of the trolleys 90, 92 and thus a parallel displacement of the supplementary carrier 82 according to arrow 103. The traction motors 100, 102, 104 are connected to the drive and / or control device 68 by lines 106, 108, 110.

On the lower flange 86, which serves as a guide surface, two vertical working cylinders 116, 118 are suspended from roller brackets 112, 114, which are coupled to one another via a third, horizontal working cylinder 120. At the ends of the working cylinders 116, 118, caliper-like grippers 122, 124 are provided, each having a fixed clamping jaw 125, 126 and a movable clamping jaw 128, 131 which can be actuated by an additional working cylinder 127, 129.

Trolleys 130, 132 are suspended from roller brackets 134, 136, 138, 140 on the lower flange 47 of the carriers 44, 46 and can be moved in the longitudinal direction of the carriers 44, 46 by means of traction motors 142, 144. The traction motors are connected to the drive and / or control device 68 via lines 143, 145.

Telescopic working cylinders 146, 148 are articulated to the trolleys 130, 132, which have hydraulic or pneumatic grippers 150, 152 at their ends and are additionally connected to the trolleys 130, 132 via swivel cylinders 154, 156.

The working cylinders 60, 62, 116, 127, 146, 154 and the grippers 150, 152 are connected to the drive and / or control device 68 by corresponding lines 61, 63, 158, 160, 162, 164, 166, 167.

2 is a working cylinder 117 with a suction, blowing or lubricating nozzle trained working member 168 is provided, the line 170 provided for air or lubricant supply is also connected to the drive and / or control device 68. The warp thread guard slats are designated 172.

For an operating example of the device described, it is assumed that a full warp beam 40 is to be removed and that an empty warp beam is to be replaced by a full warp beam. Upon a corresponding command from the signal generator 78, the support frame 42 travels along the flange supports 56, 58 to the corresponding weaving machine 10 by switching on the drive motor 64. By switching on the drive motors 136, 144, the roller carriages 130, 132 are positioned in a corresponding position in front of the goods tree 40. By actuating the working cylinders 60, 62, the grippers 150, 152 are adapted to the length of the goods tree, and then by actuating the working cylinders 146, 148 and 154, 156, the grippers are controlled towards the ends of the goods tree 40 and actuated accordingly, for removal and lifting of the goods tree according to arrow 174 (Fig. 2). The goods tree 40 can then be removed, e.g. B. on a separate industrial truck or by the device itself.

To replace the warp beam 29, the roller carriages 130, 132 are moved to the other side of the weaving machine and the working cylinders 146, 154 or grippers 150, 152 are actuated according to arrow 176. At the same time, the shafts 28 are raised by positioning the additional carrier 86 by switching on the traction motors 100, 104, 108 approximately behind the center of the shafts, as seen on the chain side. By actuating the working cylinder 120 according to arrow 121, a suitable spreading distance of the working cylinders 116, 118 is set. When the traction motors 104, 108 are switched on again, the fixed clamping jaws are moved into the shaft package 28 in the manner of a forklift truck, are firmly clamped in by actuating the working cylinders 127, 129 by means of the movable clamping jaws 128, 131 and are raised accordingly according to arrow 119. The simultaneous raising of the warp thread monitors can be provided in a known manner.

By additional actuation of the working cylinder 117, e.g. Airborne dust is removed by blowing and / or sucking or e.g. a lubrication process can be carried out.

In the exemplary embodiment according to FIG. 3, the working members 146, 154, 150 are brought up to a weft bobbin frame 178 with weft bobbins 180. In this case, the working cylinder 116 is provided with a gripper 182 rotatable according to arrow 181 and an optical sensor 184.

During operation, the weft bobbins 180 are gripped according to the arrows 188, 190, 192 and inserted into the weft bobbin console 186 of the weaving machine 10.

It goes without saying that instead of the traction motors and trolleys, for. B. magnetically or pneumatically operated linear motors could be used.
