EP2027315B1 - Combing machine with a reserve reel trough - Google Patents

Abstract

In order to relieve the operator of a combing machine from having to handle the heavy comb reels (4, 7), a mechanically operated reserve reel trough (6) is provided. It can be lowered to such a level that it can easily roll comb reels, even from the lowest position into which they are delivered by the combing machine, into the reserve reel trough. On the other hand it can be raised to such a high level that the reserve reels roll by themselves into working position on the reel cylinders (2, 3). The mechanical operation is effected preferably by a fluidically (pneumatic or hydraulic) operable work element with cylinder and piston which is arranged between the frame of the combing machine and the reserve reel trough.

Description

Technical area

The invention relates to a combing machine with at least one reserve trough, in which a reserve reel can be stored and with winding rollers through which a reel can be unwound.

State of the art

The provided for processing on the comber winding are produced on sweeping lines or winding machines. There are different embodiments of such machines are known, which deliver the combing winder at different heights. As a rule, the coils weighing up to 25 kg are transported on carriages to the combers, since it does not seem reasonable to burden the operator with the handling of the coils. At the combing machine, the wraps are stored in reserve troughs.

These reserve wells are often so deep that the reels can be loaded onto them by the carts without having to be lifted by the operator. At the latest when they have to be raised when replacing an expired coil in the higher working position, the problem arises of lifting the heavy winding.

In the EP 0 593 391 B1 Although a dump body is disclosed, which is arranged behind and above the drainage position of a combing machine. It is mounted on a pivot axis or on two unequal length levers and takes a cotton roll in reserve position. To change the roll is triggered by a working element tilting the dump body to from, causing the cotton roll from the dump body rolls into the working position on the combing machine.

This device is based on a higher than the working position stored Wadding. How the cotton wool without physical effort in this high reserve position could be lifted, makes the document no information.

General description of the invention

The invention was therefore the task of prepared Kämmwickel, which are approached on different levels of weighing on the reserve trough and to raise the over-loaded winding during the change process from the transfer position in the usually higher working position, without the operator with the handling of the winding to charge. It solves this problem with the features mentioned in the characterizing part of the main claim.

The pivoting range of the reserve trough is so far chosen that they are easy to roll over in their deepest position combing from these delivering winding car from the occurring deepest positions. This position is the reserve position, in the winding rests, until it is needed during the change process. The winding trough is then pivoted so high by a working device that the reserve roll automatically rolls on the rolling rollers, from which it runs to the Kämmorganen.

The pivoting is done by a working element that relieves the operator of lifting the heavy rolls. The working element is preferably carried out fluidly (pneumatically or hydraulically), but it can also be designed as an electric motor operated lifting spindle or in any other appropriate manner.

All jobs of a combing machine is assigned a reserve trough. The reserve troughs can be pivoted up separately at each workstation if the change processes take place at different times. However, if the changing operations take place at the same time on all work stations of a combing machine, the reserve hollow can be formed continuously and can be swung up as a whole.

Accordingly, the triggering of the high pivoting of the reserve trough can be triggered by hand individually or by an automatic control device.

Specific description of the invention

In the figures of the drawing, an embodiment of the invention is shown schematically. It shows the side view of a comber with reserve winding trough.

Of the combing machine 1, only the outlines of the machine frame are shown. Drawn, however, two winding rollers 2 and 3, on which a working coil 4 rests and is unwound under power to the pliers apparatus, not shown, the combing machine.

At the rear of the machine frame, a reserve winding recess 6 is pivotally mounted on a pivot shaft 5, in which a reserve winding 7 is stored. The reserve winding trough is connected to an energy storage, here a cylinder / piston unit 8, which is supported on the other hand on the machine frame. The means for applying the cylinder / piston unit are not shown here in detail. They include in a conventional manner a pneumatic or hydraulic pressure source and a spool.

When pressurizing the cylinder / piston unit 8 with pressure, it gives the reserve winding trough 6 so far up that the reserve reel lying in it rolls onto the reeling rollers 2, 3.

This pressurization of the cylinder / piston unit 8 with pressure can be triggered by hand, if an expired winding to be replaced by hand by a new winding. If this Replacement is automated, this can also be done automatically by the control of the automated Wechslervorganges.

The object of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

All information and features disclosed in the documents, in particular the spatial design shown in the drawings, are claimed to be essential to the invention, as far as they are new individually or in combination with respect to the prior art.
