Description

The invention relates to a method for changing cans between Transport trolley for flat cans and a textile machine according to the generic term of claim 1 and a trolley for can change for flat cans on a textile machine according to the preamble of the claim Second

The document DE 88 12 622 U1 discloses the removal of flat cans from an OE spinning machine and the filling of the OE spinning machine with a flat can on a spin box according to the preamble of claim 1. The full or empty flat cans become the spinning machine by means of a rail-bound transport carriage transported. The carriage is guided by a rail-bound pipe system, so that the transport trolley relocated to Rails is moved. The trolley is in its construction rigidly trained. However, this rigid construction of the dolly has the disadvantage that the removal or filling of flat cans an OE spinning machine can lead to malfunctions in operation and operation.

The disturbances result from the non-smooth transition of the flat cans from the spinning machine to the trolley and vice versa. The large weight of the flat cans filled with sliver has an effect in the transport cart equipped with the flat cans in the manner that the weight of the flat cans has a noticeable level difference between the can-receiving part of the trolley and the can-receiving part Part of the OE spinning machine. This level difference is particularly troublesome when filling the OE spinning machines with a flat can, because the flat can on the trolley is one lower level to the higher level of the receiver Part of the OE spinning machine is pushed. The flat jug must therefore over a higher edge of the can-receiving part of the OE spinning machine or transported across a ramp. This leads to damage to the jug in the lower area or Business interruptions.

In addition, the rail-bound transport system comes in one large production facility inevitably constantly level differences. This Differences in level result solely from the laying of the rails. In addition, the floor of the manufacturing facility generally points itself Bumps on. Ultimately, these irregularities and the rigid construction of the trolleys that the flat cans between the spinning machine and the trolley are not moved without problems can be.

So far, slivers have mostly been transported in round cans. This voluminous round cans are arranged in spinning machines in such a way that two round cans in front of two spinning stations due to their large volume had to be placed directly on the floor in a row, whereby each of the round cans supplied a spinning station with sliver. On Because of the large dimensions of the round cans, cans can be changed very easily complex and require operation by personnel. Only through that The use of flat cans is a clear assignment of a flat can to a spinning station. To profitability and increasing the effectiveness of the spinning machine are increasingly flat cans used. Flat cans have bulky ones Round cans have the decisive advantages that they absorb more sliver and by their form a clear and spinning station-related assignment enable on the spinning machine.

These flat cans are used in a further automation e.g. from a transponder car known from DE 88 12 622 U1 to the spinning machine transported. However, the problems mentioned above arose especially when moving a flat can from the trolley to the Open-end spinning machine.

The object of the present invention is therefore the removal or filling a textile machine (e.g. spinning machine) with flat cans.

This task is accomplished with regard to the method mentioned at the beginning of the features of claim 1 and with regard to the above Transport trolley solved by the features of claim 2.

As a "textile machine" in the sense of the present invention any textile machine that processes slivers can be understood. These include e.g. Draw frames and spinning machines like for example ring, air, false wire and open-end spinning machines, however, other textile machines, such as slivers be fed for processing, be suitable as e.g. Circular knitting machines used to manufacture pile fabrics and carpets fiber tapes are fed. Work organs can thus a drafting system (e.g. on a draw frame or air spinning machine), a spindle (e.g. in a ring spinning machine), an opening roller (in an open-end spinning machine) Needle cylinder (in a circular knitting machine) and the like. The The place where these organs are located is as follows designated with job. Usually has a textile machine, in which the subject matter of the application can find more than one job, but is the invention not limited to this.

For the purposes of the present invention, each “ Sliver composed of fibers are understood to be independent whether the sliver has a certain twist, as is the case with fuses or not.

As already mentioned above, the subject of the invention can be combined with different belt processing or processing textile machines or devices find application; below is intended as a concrete example of a conventional one Serve open-end spinning device 1 (Fig. 1), which will now be described.

An open-end spinning device 1 is usually part of one Open-end spinning machine 16 on one or both sides of the machine a large number of similar, arranged side by side Has open-end spinning devices 1. Any open end spinning device 1 has a spinning element shown in FIG Execution designed for example as a spinning rotor 10 is. The spinning rotor 10 is in a known manner by means of a Shaft 100 stored and is in the embodiment shown driven by means of a tangential belt 101. The Spinning rotor 10 is arranged in a rotor housing 102, the Interior 103 via a suction pipe connection 104 with a not vacuum source shown is connected.

An elongated can 411 and its guidance shows Figure 2. Your two long sides can thus serve as a guide with whose help the can 411 from route 7 to the open-end spinning device 1 between two guides 160, 161 is performed. With this Embodiment can, if desired, on the Can 411 lugs 402 may be provided, between which the band end 430 is held, which - as described - with a length b protrudes over the edge of the jug 411 and hangs down there.

Figure 4 shows a series of twenty-three spinning positions one Open-end spinning machine and a trolley 8 for transportation of flat cans (cans 411) and for the exchange of such 411 cans at the spinning positions. The trolley 8 includes a can receiving portion 82 and two end portions 83, 84. The can receiving portion 82 is through partitions 820 in Subdivided subjects, each subject to accommodate one Flat can (can 411) by moving the flat can in its Longitudinal direction is suitable.

Each end portion 83, 84 carries a post 830, and the posts in turn carry a bar 831, which acts as a guide rail serves for a can manipulator 85. The can manipulator 85 is movable in the longitudinal direction of the bar 831 and thereby the can be delivered to individual compartments of the can-receiving part 82. The can manipulator 85 comprises its own rail 850, which is perpendicular to beam 831 and as a guide rail for a 851 can slide. The can slide 851 includes a gripper (not shown) which is moved by a movement in Direction of the central plane of the open-end spinning machine Can 411 from the trolley 8 to the operating position in the machine or by movement from the central plane the machine away from its operating position pulls on the trolley 8.

Each end part 83, 84 of the transport carriage 8 also has wheels 86, which the movement of the vehicle in directions perpendicular to Allow the long side of the cans. The dolly 8 comprises a drive (not shown) and possibly one Control, which is a steering system (not shown) for the wheels 86 controls. When the trolley 8 runs the route 7 leaves, it is loaded with ten full cans, one compartment for Recording from an empty jug remains free. A reasonable number von Kannen 411 is between two and twelve.

The trolley 8 is controlled by an investment in a selected spinning station at which the can 411 to be replaced is. With a suitable positioning system (here not shown) the transport carriage 8 is initially positioned in such a way that the empty compartment on the spinning station (open-end spinning device 1) is aligned where to replace the can 411 is. The can manipulator 85 is assigned to the empty compartment, and the can slide 851 is opposite the machine moved inward so that its gripper (not shown) the can be exchanged can 411. With a movement of the 851 can slide valve to the outside of the machine the can 411 to be replaced in the previously empty compartment of the Transport car 8 pulled.

The trolley 8 is then moved to one with a full can 411 occupied compartment with the relevant spinning position align. The can manipulator 85 becomes the bar 831 moved along to the can manipulator 85 of the newly inserted Can 411 to be delivered. By moving the can manipulator 85 inside (opposite the machine) this becomes full Can 411 then moved to the operating position.

The transport carriage 8 can now be another selected one Spinning station where the procedure is repeated, now the empty compartment on the trolley 8 is not on the original Place, but at the point of last to the Machine dispensed full jug 411. By repetition this procedure will move the empty compartment step by step until all full cans 411 are inserted into the open spinning machine have been replaced by empty (or at least exchangeable) Cans 411 have been replaced. The trolley 8 is then moved back to route 7.

As indicated in FIG. 4 by double arrows 821, the can-receiving part 82 is height-adjustable relative to the end parts 83, 84 stored to the cans 411 of the same height Part 82 in its loading or unloading position on route 7 or the open-end spinning machine or another textile machine or device - and of course in reverse Direction - to be able to move. Similarly, too other elements such as B. the tape feeder 5, tape start preparation device 9 (described below will) be stored adjustable in height on the trolley 8.

The flat can 411 shown in Figures 2 and 3 has two side walls 415, 416 arranged in parallel, which are the width of the can define i. The can 411 also has two end pieces 417, 418, which connect the side walls and the can length define j. In FIG. 3 there are rounded end pieces 417, 418 shown, but this instead of round also perpendicular to the side walls 415, 416 stand or be designed as polygons can. The jug length j is significantly longer (e.g. three to four times larger) than the can width i, which is essentially the width of a spinning station, d. H. an open-end spinning device 1, corresponds. In this way it is achieved that Capacity of the flat jug 411 the capacity of one usual round jug corresponds. The capacity should be a flat jug 411 the capacity of one Round can with a diameter of 450 to 500 mm. If it is assumed as an example that the diameter a conventional round jug is approx. 457 mm, then one has Flat can (can 411) according to FIG. 3 with a width of 230 mm and a length of 780 mm a slightly larger capacity than the round jug. In other words, the length of the flat jug does not have to be twice the round can diameter in order to to give the same capacity.

The height of the jug (round or flat jug) is determined by the Construction of the spinning frame given the cans 40, 41 or 411 must be placed under the spinning station.
