Description

Bale opener for opening compressed fiber bales having an improved basic design

Technical Field

The invention relates to a bale opener for opening a compacted fiber bale arranged in a setting direction, having a machine frame and a pick-up unit, wherein the pick-up unit is arranged at the machine frame in a height-variable manner, and wherein the machine frame can be moved in the setting direction such that the pick-up unit can be moved over the fiber bale and can pick up fiber material from the fiber bale, wherein the machine frame has a door-shaped structure having a first side frame and a second side frame, wherein the first side frame is guided on a slide rail, wherein two portal profiles running parallel to one another are formed between the side frames, extend in a transverse direction and are coupled with their ends in the region of the upper corners of the side frames.

Background

DE 37 34 480 A1 or DE 36 578 A1 discloses a bale opener for opening a compressed and aligned fiber bale in an alignment direction, and having a machine frame, at which a pickup unit is arranged in a height-variable manner. The machine frame can travel in the arrangement direction of the fibre bales, so that the pick-up unit can drive over the fibre bales and can pick up fibre material from the fibre bales. For this purpose, the pick-up unit has a pick-up roller which is set in rotation and takes out the fiber pile from the fiber package, and the fiber pile can then be carried away by the suction mechanism.

In designing the bale opener, it is important to operate continuously, so that the fiber bales can be placed as far as possible without interrupting the operation of the machine, while the bale opener picks up fiber bales from other placed fiber bales without interruption. It is therefore necessary to supply bale openers with fibre bales in such a way that they must be arranged in their arrangement direction in the arrangement channel. The machine frame runs over the fibre bale until the fibre bale is completely stripped, and the machine frame is subsequently switched to the subsequently placed fibre bale by a running process in the placement direction in order to continue the stripping process. Depending on the space conditions, the installation of the fiber bales in the installation channel is troublesome here, mainly because the fiber bales have to be moved by industrial transport vehicles.

For this purpose, known bale openers have rails mounted on the base and extending at a distance from one another, on which rails the machine frame can travel in the installation direction. In this case, it is disadvantageous that the land transport vehicle must travel on rails laid on the base, so that it usually takes a route directly into the installation shaft without running over the rails. Especially when a plurality of bale openers are operated in parallel, the logistics for supplying each of the bale openers with fibre bales becomes difficult if a corresponding number of rails are laid on the base.

Known structures of the frame of the bale opener comprise a steel frame construction, wherein drives for various movements of the bale opener are arranged at the steel frame construction. For example, a motor for height adjustment of the pickup and a motor for traveling the carriage in the settling direction are arranged on the upper side of the carriage. However, in order to control the bale opener, an electrical control unit is required, which, due to the reduced construction of the machine frame, has to be arranged externally, so that the electrical control unit has to be operated as a peripheral device. Therefore, long line conductors are required, which is disadvantageous in particular for the operation of the sensor mechanism and the power unit (e.g. the travel motor).

Disclosure of Invention

The object of the invention is to improve the basic design of a bale opener for opening compressed fiber bales. The aim of the invention is to simplify and/or increase the productivity of the supply of fiber bales to bale openers.

Another object of the invention is to structurally optimize the frame of the bale opener so that it receives as much as possible the main functional units for the operation of the bale opener.

This object is achieved by the bale opener as claimed in the present application. The bale opener claimed in the present application represents an advantageous development of the invention.

The invention comprises the technical teaching that the second side frame is guided on a base on which the fibre bales are likewise placed, and wherein the slide is configured to be fitted on the same base on which the second side frame is likewise guided, and wherein the pick-up unit is at least indirectly received in a suspended manner at the portal profile.

The basic idea of the invention is to guide the machine frame in the setting direction only on one side, although the machine frame is constructed in a door-type construction. The bale opener therefore only deals with the guidance of the machine frame with a single slide rail, while the second side frame is guided only through the base and only in the height direction. The region of the bale opener located opposite the sliding rail can thus be implemented by a continuous, uninterrupted base, so that the fiber bale does not only have to be deposited by the depositing channel, but can also be delivered to the bale opener laterally with respect to the deposition direction. It has already been shown that it is sufficient to guide the machine frame in the manner of a gate only on one side, in particular if two rolling rollers (working rollers) arranged at a distance from one another on the first side frame are guided on the slide rail and two further rolling rollers received on the second side frame can roll on the base without a further slide rail being required for this purpose. Other components of the bale opener, in particular the guide for the intake of wind, can be arranged on the side of the first side frame, for example parallel behind the slide rail, so that the placement area for placing the fiber bales can have, for example, only one boundary marking, which is free of other base structures.

A particular advantage is achieved if the slide rail is configured to fit on the same substrate on which the second side frame is also guided. The slide rail is therefore also configured in particular to be fitted on a base on which the fibre bales are placed. However, due to the portal structure of the machine frame, the skid rails do not have to bear any moment, and the pick-up unit does not have to be configured as a unit projecting from the tower, so that also no greater moment is generated, which has to be compensated for, for example, by a counterweight. Nevertheless, the advantage of a freely fed fibre package is obtained as is known in laterally cantilevered pick-up units, which are height-adjustably received at a pick-up tower. Furthermore, the pickup can be implemented longer than in a tower-like embodiment, whereby the production rate of the bale opener can be increased to 2500kg/h, for example.

The door-like structure of the machine frame is embodied in such a way that two portal profiles running parallel to one another are arranged between the side frames, extend in the transverse direction of the machine frame, and are connected with their ends to the side frames in the region of the upper corners of the side frames.

The design of the portal profile and the mounting of the portal profile on the side frames only on one side enables the machine frame to be designed such that the two side frames have a deliberately limited torsional stiffness in the transverse direction with respect to one another, so that irregularities in the base do not lead to the rollers arranged below the side frames for rolling on the slide rails and on the base losing contact with the rails or the base. The portal profile forms the desired flexibility for connecting the two side frames, wherein, however, a directional stability for the travel of the machine frame in the setting direction remains to be achieved. In this case, the side frames can be rotated relative to one another over a small angular range about an axis running in the transverse direction, wherein excessive tensioning in the connection of the frame or portal profile to the side frames is still prevented.

This results in a further particular advantage: the pickup unit can be received in a suspended manner at least indirectly at the portal profile. In this case, it may be sufficient for the pickup unit to be guided between the side frames only at the portal profile, wherein, however, the weight of the pickup unit is absorbed by the portal profile. In particular, it has proven to be advantageous to arrange a bridging element between the portal profiles, for example in the vicinity of the respective end side of the portal profiles and therefore adjacent to or close to the side frame, wherein the pickup unit is accommodated suspended at the bridging element, for example by means of a pulling device, wherein the bridging element is in turn supported by the portal profiles. The portal profiles are located in the corner regions of the side frames, and the traction means are received centrally between the portal profiles at the bridging element.

It is further advantageous here if the pulling means also receive the pickup units as far apart from one another as possible, so that the pulling means are arranged, for example, outside the pickup units and thus close to the side frames. The pickup unit extends substantially only between the inner sides of the two side frames and is not guided into the side frames, in particular by the fastening means for taking up the weight force.

A particular advantage of the door-like structure with corresponding side frames is that a receiving space can be formed in each of the side frames, in which receiving space components for operating the bale opener are received. For example, a drive unit for generating a travel movement of the machine frame can be arranged in the first side frame. It is also conceivable that at least one electrical control unit for controlling the bale opener is arranged in the second side frame. Thus, all the important functional units for the operation of the bale opener are already accommodated in the housing and the peripheral electrical control unit can be essentially dispensed with. This results in short line connections, in particular between the control unit and the sensors, motors, actuators, etc., so that a simple construction and reliable operation of the bale opener is ensured.

A particular advantage is achieved if at least one, but preferably two, rolling rollers driven by the drive unit are received in each case at the first side frame, which rolling rollers roll on the rail or the base in order to receive the respective first and/or second side frame. Two rolling rollers can be arranged on the second side frame, which are arranged on the substrate in a rollable manner for guiding the second side frame. This results, for example, in four rolling rollers arranged on the machine frame, which rollers substantially uniformly bear the weight of the machine frame and in particular of the pickup unit. Guiding on the substrate means guiding of the second side frame on the surface of the substrate.

The side frame may be implemented such that the side frame has a lateral dimension that is wider than the width of the pickup unit. The width is the dimension of the respective side frame horizontally in relation to the base or the slide rail when the bale opener is moving in the direction of movement over the bale. Accordingly, the distance between the rolling rollers at the respective side frames can be increased, which is advantageous for standing safety and thus stability of the bale opener. Furthermore, the passive safety is increased, since it is more difficult to reach the pickup, and thus the dangerous area of the bale opener, from the longitudinal side of the bale opener, i.e. substantially transversely to its travel path, for example with a land vehicle. Furthermore, the side frame provides a location for the sensing mechanism, which is advantageous for active safety. Additionally or alternatively, a maintenance window is introduced in the side frame, through which accessibility of the pick-up unit is provided. For this purpose, the pick-up unit only has to be moved to a height corresponding to the height of the maintenance window, thereby ensuring the accessibility of the pick-up unit. The maintenance window can be formed, for example, in the side frame above the components of the electric control unit and above the components of the drive unit.

There is also a suction mechanism having a channel for guiding the suction wind. The channel of the suction device is arranged parallel to the sliding rail on the outer side facing away from the placement area. It is particularly further advantageous to establish power (electrical) and signal connections at the channels of the suction mechanism, wherein the power and signal connections may comprise a tow chain mechanism. The power and signal connections are further advantageously located outside the channel such that the slide rail is on a first, inner side of the channel and the power and signal connections are on an oppositely disposed, second, outer side of the channel. The bale opener may in particular have one side of the suction mechanism and power and signal connection arranged adjacent to a wall of the building, since the accessibility of the bale opener from this side is not permanently required for the operation of the bale opener.

Detailed Description

Fig. 1 and 2 show a bale opener 1 having the features of the invention in two different perspective views. The bale opener 1 serves to cut off fibre bales 100 on the upper side, which are arranged in a plurality of rows, side by side in the arrangement direction 10, in a placement region 28 on the base 16. For paring the upper side of the fibre bale 100, a pick-up unit 12 is used, which is received at the machine frame so as to be vertically movable in fig. 1 towards the base 16 or away from the base. The chassis 11 has a first side frame 13 and a second side frame 14. Two spaced apart portal profiles 17 extend between the two side frames 13 and 14.

The side frames 13, 14 have rolling

rollers

22 and 23, and for guiding the machine frame 11 in the installation direction 10, a sliding rail 15 is used, on which the rolling roller 22 at the first side frame 13 is guided, for example. Rolling rollers 23 on the underside of the second side frame 14 run on the base 16, the fibre package 100 likewise resting on the base 16 and preferably also on the base 16 fitted with a slide rail 15.

The pick-up unit 12 has, illustratively, two pick-up rollers 31 and three support rollers 32 on the underside. The pick-up rollers 31 are located between the support rollers 32 and the axes of rotation of all

rollers

31, 32 run parallel to each other in the transverse direction 18. Before the pick roller 31 is a dust bar 33. If the

rollers

31, 32 are set in rotation, the picking roller 31 picks up the flocked component from the pressed fiber bale 100 and the fiber fleece is sucked off by the suction device 26 and fed to its other application.

The suction mechanism 26 comprises a suction hood 34 which is located on the upper side of the pickup unit 12 and to which a spiral hose 35 is coupled which is directed vertically upwards. The length of the spiral hose 35 may be changed while the pickup unit 12 travels in the vertical direction, and the spiral hose 35 is coupled at the upper side with an air suction duct 36 that introduces suction air into the first side frame 13 at the upper side. Accordingly, the air suction pipe 36 is self-supportingly coupled to the upper side of the first side frame 13, and the spiral hose 35 is suspendedly disposed at an end of the air suction pipe 36. Here, the intake air moves to the first side frame 13, and reaches the reprocessing station together with the fiber pile through the passage 27.

Manual control of the bale opener 1 is effected by means of an operating table 37, which is arranged, for example, on the front side of the passage 27. The power supply of the bale opener 1 is realized by a terminal block 38, which is located at the same front end of the channel 27. The power supply and signal connections to the movable frame 11 can be established by means of power and signal connections 29 including a drag chain unit 30, wherein the power and signal connections 29 are located at the sides of the channel 27. A driver 39 forms a movable coupling of the channel chain unit 30 and is coupled to a belt lifting unit 40, which is connected to the first side frame 13 and thus moves together with the movement of the machine frame 11 in the setting direction 10. The belt lifting unit 40 serves to lift the cover belt 45 that covers the passage 27 at the upper side.

Fig. 3 shows a further perspective view of the bale opener 1, wherein the second side frame 14 is shown open. The side frames 13, 14 each have a receiving space, in which means for operating the bale opener 1 are received. An electronic control unit 21 of the bale opener 1 is advantageously integrated in the second side frame 14, wherein the electronic control unit 21 monitors and controls the main movement functions and the sensor means and the associated actuators of the bale opener 1. The frame 11 is therefore configured to receive the main functional mechanisms for operating the bale opener 1, wherein advantageously the electrical control unit 21 is arranged at the unoccupied second side frame 14. The receiving space is accessible through a door, not shown, wherein the accessibility is optimally provided, in particular, by the separate second side frame 14. The operator can thus access the electrical control unit 21, wherein, in a manner not shown, in particular, an input/output interface can also be arranged on the second side frame 14, which input/output interface can be redundant in its function, can additionally be implemented and/or can supplement the control panel 37.

The pickup unit 12 is received at the bridging element 19 of the machine frame 11 by means of the pulling means 25, and the bridging element 19 is arranged at the portal profiles 17 running parallel to each other. The pulling means 25 forms a pulling belt with integrated steel pulling stays, and the pulling means 25 surrounds a reversing wheel 42 arranged at the bridge element 19.

Fig. 4 shows a further perspective view of the bale opener 1 with a frame 11, which comprises a first side frame 13 and a second side frame 14, wherein the perspective view shows the first side frame 13 in an open arrangement. The main components received in the first side frame 13 include a drive unit 20 for driving rolling rollers 22, which are driven by the drive unit 20 by means of a belt 41. Here, the illustration shows a belt pulley which is arranged to the front side of the rolling roller 22 and thus covers the rolling roller.

In addition, a part of the suction device 26 is received in the first side frame 13, and the suction pipe 36 passes through the upper top region of the first side frame 13 and continues via a removable air duct section 43 in the first side frame 13 in order finally to reach the not shown belt lifting unit.

Fig. 5 shows a cut-away view of the bale opener 1 and here the section extends through the door frame profile 17 and the pick-up unit 12. On the rear side, a first lateral frame 13 is shown, by means of which the electrical contacting of the movable frame 11 takes place. The machine frame 11 serves in particular for guiding power and signal cables together with the portal profile 17, for which purpose the portal profile 17 comprises a hollow chamber 44, through which the power and signal connections connected to the power and signal connections 29 according to fig. 1 are guided further. The electrical control unit 21 can thus be contacted via the portal profile 17, wherein power and signal connections are likewise routed back to the first side frame 13 via the hollow chamber 44 in the portal profile 17, in particular for the control and operation of the drive unit 20. A short guide path is thus obtained between the terminal block 38 and the electrical control unit 21 in the second side frame 14, as shown in fig. 1 and 2, to which the power and signal lines are guided via the hollow chamber 44. Preferably, advantageously shielded signal lines are led through one portal profile 17 and power lines are led through the other portal profile 17. So-called crosstalk between power and signal lines can be reliably prevented or avoided.

The embodiments of the present invention are not limited to the preferred embodiments described above. On the contrary, many variants are conceivable which can use the illustrated solution even in fundamentally different embodiments. All the features and/or advantages derived from the claims, the description or the drawings, together with details of construction or spatial arrangement, are essential to the invention, both individually and in the broadest possible combination.
