EP0338302A1 - Method and apparatus for putting fibre bales in readiness along a bale-plucking machine - Google Patents

Abstract

So that, in a spinning mill, the bale opening can also be carried out over the weekend with reduced labour, hitherto the bale settings on the machine itself have been kept correspondingly high, and this has led to a greater machine outlay. <??>According to the invention, the handling of the fibre bales (9) is to be prepared in such a way that the fibre bales are in readiness as groups (10) on the spinning-mill floor (1), on which the fibre-bale opening machines (2) stand, and can be displaced into the operating position manually by the reduced personnel present. <??>To accomplish this, there are designed loading carriages (13) according to the invention, on which or by means of which groups can be gathered together and made available on the spinning-mill floor. <IMAGE>

Description

The invention relates to a method for providing fiber bales according to the preamble of the first method claim and a device for carrying out the method according to the preamble of the first device claim.

Known from practice are the fiber bale removal machines, which move back and forth on a rail along a row of fiber bales and thereby loosen and transport fiber flakes from the surface of the bale row by means of a rotating removal member. Such a machine is sold worldwide by the applicant under the name UNIFLOC.

Such machines are usually set up in halls specially designed for the installation of fiber bale removal machines. Such halls are provided with a carefully leveled floor, which usually has a predetermined surface quality.

Before they can be broken up, however, fiber bales must be freed and cleaned externally by combing in the bale opener from the transport packaging, which contains steel strips for holding together and sack materials for protecting the bales, before they can be classified in the operating series, as a rule is carried out in another part of the building with conventional floor quality, in which, depending on the organization, the delivered bales are also stacked.

Furthermore, the unpacked and pre-cleaned bales must be brought individually from forklifts from one room to the room in which they can be placed in the above-mentioned series of operations.

The disadvantage now is that such a way of working not only requires the corresponding transport material and the associated personnel on the one hand, but also that this work is only carried out on five days of the week, while the fiber bales are released continuously throughout the week, i.e. should also be done on weekends. However, with the aforementioned transport methods, this requires very long travel times and large operating areas for the bale rows, as well as the corresponding personnel, so that such a machine can continue to work over the weekend and in the morning of Monday until a new bale row has been set up again in the operating position.

It is therefore an object of the invention to find a method and a device by means of which the areas of the operating rows of the fiber bales can also be kept in size over the weekend nen, which only includes the necessary mixing of different types of bales. In other words, the driving distance of the material removal machine does not have to be greater than is necessary for the compilation of the necessary mixture.

The object is achieved by the method step mentioned in the characterizing part of the first claim and by the device mentioned in the characterizing part of the first device claim.

Further advantageous embodiments are defined in the further claims.

The advantages achieved by the invention can be seen essentially in the fact that the in the waiting position, i.e. fiber bale groups assembled in the position outside the operating position manually, i.e. due to the fact that a reduced number of staff can be shifted into the operating position over the weekend and that there can be enough bales in the waiting position without the supply of bales from the bale opening facility mentioned.

In the following, the invention is explained in more detail with the aid of drawings showing only execution routes, it shows:

• Fig. 1 shows schematically a floor plan of a spinning mill floor in which fiber bales are opened by the fiber removal machine and a spinning mill floor in which the delivered fiber bales are stacked on the one hand and prepared for loading onto means of transport.
• Fig. 2 is a view of a device according to the invention, shown semi-schematically

• Fig. 10 plan of the combination of Fig. 9, plan of a variant of the device according to the invention
• 11 shows a variant of the device according to the invention, shown in plan and in a row of such devices.

Fig. 1 shows schematically a spinning mill floor 1, on which a fiber bale machine 2 known per se is shown.

This stripping machine comprises a stripping member 3 and rails 4, between which a fiber conveying channel (not shown) is provided. Such machines are known per se and are sold worldwide by the applicant under the name "UNIFLOC", which is why no further description is given.

Parallel to, and to the left and right, as seen in FIG. 1, each of the rails 4 has a row of fiber bales 5 and 6 respectively in the operating position poses. The operation can be such that either the bale row 5 and then the bale row 6 are removed or the bale row 5 and 6 can be removed alternately in order to remove a mixture of both bale rows simultaneously in a manner known per se.

1 shows on both sides of the bale rows 5 and 6, one bale row 7 and 8 respectively, which are in a so-called waiting position.

From this waiting position, the bales 9, which are combined to form a group 10, are brought into the operating position as a whole group. Of course, only after the empty loading wagons described later used to hold the bales have been removed from the production line.

The loader wagons are designed in such a way that an entire bale group can be pushed manually into the operating position by the existing weekend staff.

It goes without saying that the waiting position of the individual bale groups 10 does not necessarily have to be set up in a row and parallel to the operating positions, but, since the entire groups can be moved manually, they can also be in a waiting position somewhere on the same floor.

1 shows a further spinning floor 11, which can be provided either next to the spinning floor 1 or on another floor or in another building of the spinning mill, in which, for example, also delivered fiber bales are stored, freed from the packaging and superficially cleaned, so that they can be combined into a group 10 on a loading wagon 12 described later (FIG. 11) - which is shown schematically with the arrows 14 - and on such a loading wagon on the spinning floor 1 a towing vehicle (not shown) can be moved into a waiting position.

A variant of this is that the individual bales are loaded onto carriages 13 to be described later (FIGS. 2, 3 and 9) and these individual carriages are combined to form a group 10, which is shown schematically by the arrows 15 and one which is joined together in this way The wagon assembly as a whole is brought into a waiting position on the spinning floor 1 by means of a towing vehicle.

Within this variant there is also the further variant that the individual carriages 13, on each of which a bale 9 is provided, are individually shifted into a waiting position on the spinning mill floor 1 - which is shown schematically by the arrows 45 - which, for example, is then the case can, if the spinning floor 11 is provided immediately adjacent to the spinning floor 1 and thereby the spinning floor 11 can also be declared a waiting position.

2 and 3 show a loading wagon 13 for receiving a fiber bale 9.

The carriage 13 comprises two non-lockable castors 16 and two lockable castors 17.

To get optimal mobility, the arre animalable castors 17 in the central region, ie in the region of the transverse axis (not shown) of the wagon, seen in the longitudinal direction of the loading wagon, and the non-lockable castors 16 in the region of the longitudinal axis (not shown) and at the two end regions of the wagon.

The swivel castors 16 and 17 are known per se and are sold, for example, under the brand name BLICKLE by Heinrich Blickle GmbH, CH-3063 Ittigen. The lockable rollers 17 are modified in that a lever provided thereon is removed, which removes the locking bolt 18 from the locking cams 19 which are arranged on a turntable 20 with a predetermined number. Instead of the aforementioned lever removed, the locking cam 19 is connected to a cable (or chain) 21 which is fastened to a shaft 22. The locking cam is pulled into the locking groove by a spring (not shown).

As shown in FIG. 3, the locking cams 18 of both lockable castors 17 are connected to the shaft 22, and the shaft 22 is also rotatably mounted in pivot bearings 23.

Furthermore, the shaft 22 is connected to a pedal 24 at both free ends, so that each locking cam 18 can be pulled out of the corresponding locking grooves by means of session 21 by foot pressure on the pedals 24, whereby the lockable castors become free castors.

This is necessary so that the loading wagon 13 ver in the directions of travel A as well as in the directions of travel B. can be pushed. One push against the loading wagon 13 is sufficient to let the actual castor turn when the castor 17 is unlocked, until the respective locking cam 18 engages again in a lock groove offset by 90 ° C, thereby displacing the castors 17 by 90 ° C to the original position. The castors 16 and 17 are each attached to the carriage 13 with a stationary disc 25.

Likewise, the non-lockable castors have a turntable which, however, in contrast to the turntable 20, has no locking grooves.

In order to fix the loading wagons 13 in a predetermined position in the row 5 or 6 or in any other place in the waiting position, the loading wagons 13 are provided with at least 2 fixing means 26, which have a lowerable foot 27, which is on the Spinning floor rests with a certain pressure, so that the loading wagon is no longer movable. Such fixing means are known per se and are also used, for example, for locking doors. As a rule, they have a housing in which a piston connected to the foot can be moved downward against a spring pressure and fixed by a clamping action. A further pressure on an unlocking lever (not shown) loosens the fixation so that the piston is moved upwards again by the spring force. There is no need to describe such fixatives further.

In order to be able to move the loading wagon 13 by means of a drawbar 31, it comprises both End faces 28 and 29 have a bore 30 (see FIGS. 3 and 5) into which the drawbar 31 can be pushed.

In order to fix the drawbar 31 in the bore 30, the drawbar comprises a pivot lever 32 with a fixing cam 33, which is pressed into a recess by the force of a spring 33.

Furthermore, the carriage 13 has four recesses 35 with a groove 36, into which a pair of brake shoes 37 with a wedge 38 can be inserted. The wedge 38 engages in the groove 36. As a result, the pair of brake shoes 37 is held in the recess 35 in a rotationally fixed manner.

The brake shoe pair 37 serves to receive a support rod 39 which is pivotally provided in the brake shoe pair 37.

As can be seen from FIG. 2, the support rods 39 serve to prevent the balls 9 from tipping over on the loading wagon 13.

This support rod 39 is inserted together with the pair of brake shoes 37 and removed therefrom as required.

E.g. support rods can be provided for transport on both sides or if the carriages in the row 5, 6 or 7, 8 shown in FIG. 1 are provided at the end of the row, a support rod can be provided for the outermost carriage.

This is due to the braking effect of the brake shoes Support rod 39 can be pivoted, but is braked in such a way that the support rod 39 can be pivoted by means of a predetermined pressure which is greater than the self-weight component of the support rod in the respective inclined position of the support rod.

In the event that the support rod is provided on the outermost carriage of a row 5, 6 or 7, 8, when the fiber bales are removed, the support rod is pivoted downward by the removal member by the amount by which the removal member for the corresponding passage deeper into the Fiber bale surface was placed. In this way, the support rod 39 does not interfere with the removal, but is also essentially horizontal after the bales have been removed.

The support rods 39 are only provided on the long sides 40 and 41 of the carriage 13.

Ultimately, the wagon 13 still has two recesses 42 in each wagon corner, which are used to assemble individual wagons 13 into a group. In this case, those sides which are opposite to another side of the carriage are provided with a fixing bolt 43 shown in FIG. 8 and inserted into the recesses 42, so that the carriages 13 are mutually fixed.

In addition, fixing brackets 44 can be inserted into the same recesses 42, as shown in FIGS. 9 and 10, which ensure that the carriages are held together.

The length L of a car becomes the longest possible length adapted to a fiber bale 9, which also applies to the width M, so that the carriages lie against one another when forming a group, as shown in FIGS. 9 and 10.

11 shows a variant of the wagon 13, a loading wagon 12, the variant being that this wagon has a size which allows a plurality of bales to be placed on it as a group. In the example of FIG. 11, five bales (indicated by dash-dotted lines) are placed.

Corresponding to the size of the carriage 12, in comparison with the carriage 13, the carriage 12 has a larger number of rollers 16 and 17, and in this case too the rollers 17 are placed in the middle part of the carriage in order to give the carriage optimum mobility . For example, four lockable castors are provided in the middle part in FIG. 11, two and two being opposed to one another, so that the shafts 22 are arranged at such a distance from one another that the pedals 24 are directed towards one another, so that both can be pressed with one foot opposing pedals 24 can be operated. As a result, all four lockable castors 17 are released with a foot pressure until, after the carriage 13 has been moved, the locking cams 18 come to rest again in the locking grooves 19.

As shown in FIG. 1 and described accordingly, such a carriage is loaded with the appropriate number of bales outside of the floor 1 and transported to the floor 1.

In the examples shown, the loading wagons are included Rollers provided, but it is understood that other displacement means can be used, for example an air cushion, with the exception of the roller and the accessories of the rollers, the other elements can also be used.
