Description

DESCRIPTION

Safety device and method for a

Discharge device of a baler

The invention relates to a safety device and a safety method for a discharge device of a stationary baler and a discharge device having the features in the preamble of the main claim.

In practice, stationary balers are for

Production of pressed bales from cut fibers, in particular synthetic fibers, known. Such balers have inter alia a discharge device for supplied short-cut fibers, in particular

Synthetic fibers. In the production of such pressed bales problems with the production and operational safety were found in practice.

It is an object of the present invention to provide a

Improved safety technology for a baler show.

The invention solves this problem with the features in the independent claims.

The claimed safety technique, i. the

Safety device and the safety method, and the thus equipped discharge device as well as stationary baler and baling plant have

different advantages.

The safety technology has a detection device or a detection method, which detect a winding formation of fibers on the discharge device. The detection device is designed and arranged accordingly for this purpose. If by means of detection a Winding is detected, the

Safety device trigger a suitable safety measure.

With the invention it has been recognized that the problems, e.g. Fasergutkontaminierungen, on a possible

Faseranlagerung and a winding of fibers can be returned to the discharge. Such fiber wraps can be formed in particular on single or multiple existing movable, in particular circulating moving, discharge. The winding can have several and different causes. The

Fiber wraps may e.g. by adhering fibers to parts of the discharge device, by mutual

Sticking of fibers or even defects in the

Fiber cut and fibers with excess length and by

Clumping of fibers arise. A filament wrap may adhere to parts of the dispenser.

Under a filament winding becomes a coherent

Collection of fibers understood that a certain

Has strength and dimensional stability. It can be formed by an accumulation of fibers and grow by the addition of other fibers. It can also condense, e.g. by a relative movement of parts of the

Discharge device and by internal fiber movements. The fiber wrap may e.g. have a lumpy shape and / or an elongated, plait-like shape. A filament winding can also be a possibly moving part of the

Discharge device, e.g. a rotating shaft,

to wind around.

The fiber wraps can on the discharge

remain and can be different disorders

cause. In a fiber change fibers from the winding in press operation in small parts again

be discharged and contaminate the new fiber. On the other hand, fiber wraps can control the movements of the

Hinder discharge means. They can be grated and

dirty or overheated and charred. This can also lead to contamination. Fiber wraps can also be in a freewheeling gap between a

Discharge means and a surrounding housing of the

Get discharge. You can also get into the storage area of the movable discharge.

Certain types of fibers, especially synthetic fibers, also have a low melting temperature and

Ignition temperature. In conjunction with mechanical friction, this can lead to dripping of melt in the subsequent press area and to contamination and a fire hazard.

With the claimed safety technology such wind-related disorders can be detected in good time and also preventively prevent.

The safety technology is preferred

Assigned discharge. The safety technology can in the way of original equipment manufacturer at the

Dispensing arranged, in particular integrated. The safety technology can also be retrofitted to an existing discharge or

to be converted. The safety technology can be an independent technical and economic unit. It can also be part of a discharge device, a baler and a baling plant.

In an advantageous embodiment, the

Detection device and the detection method

provided and configured, a winding of fibers on a freewheeling gap and / or on a storage of one or more movable discharge means,

in particular rotating discharge rollers, the

Discharge device to detect. The detection can detect a winding formation of fibers directly and / or indirectly. The

Detection device and the detection method can be provided and designed accordingly for this purpose.

Immediate detection is e.g. optically by an optical sensor, e.g. a camera or otherwise possible. Indirect detection may e.g. done by detecting a temperature increase. Other physical consequences of winding formation may also be detected, e.g. by detecting noises, gas evolution, power changes or the like .. A temperature increase can be made in particular in the range of a freewheeling gap and / or storage of a discharge. At a freewheeling gap there is the greatest risk of undesirable accumulation of

Fibers and the formation of a filament winding. This is especially in the case of a roller-shaped discharge with a large diameter and a correspondingly large peripheral speed in the area to the adjacent

stationary housing and a local inlet gap of the case. When filling the fiber in the

Discharge device may u.U. Fibers fall into the freewheeling gap.

A temperature increase can be sensory detected in different ways. Conveniently, an arrangement of one or more thermal sensors in the range of one

Freewheel gap and / or storage. The one or more thermal sensors may be arranged on the housing of the discharge and / or on the movable discharge, in particular a rotating discharge roller, for example on the shell, shaft or shaft. An arrangement of the sensor in the jacket area with a corresponding radial distance from the axis of rotation is advantageous and detects a heating directly at the local freewheeling gap.

A thermal sensor may e.g. be designed as a heat sensor for detecting a heat conduction on the housing and / or discharge. Alternatively or additionally, other sensory detection options are provided, e.g. by an optical heat detection by a thermal imaging camera, in particular infrared camera or the like ..

The detection of a winding of fibers

Thermal ways has the advantage that a winding formation on the one hand with sufficient detection security and on the other hand in good time before the said

Disturbances, e.g. Melting and / or ignition of fibers, can take place. The one or more thermosensors can respond to a triggering temperature in the range between a normal operating temperature and a generally much higher melting temperature and / or

Ignition temperature is. When crossing the

Triggering temperature, the safety device can respond appropriately. The triggering temperature can be fiber-specific. It can be defined or specified.

The safety device can except the

Detection device, a display and / or a

Have safety actuator, which a

Safety measure on the baler performs. A display and a safety actuator can be present individually or multiple times. It can also be several

give different displays or security actuators.

A display may optically and / or acoustically and / or haptically a signal, in particular an alarm signal,

submit. This can be eg a visual and audible alarm signal and a warning or fault message to the control station of a baler or baler his .

A security actuator may e.g. the baler

automatically turn off. The same or another safety actuator can switch a fiber feed to the baler. In this case, the fiber supply to the baler can be blocked. On the other hand, the fiber supply can be redirected in a redundant manner to another available or possibly already running baler.

The formed filament winding can be suitably

be removed, e.g. by manual intervention on the deactivated baler or switched off

Discharge device.

Another preventive safety measure may be preferred in a purging air or other

gaseous fluid attached to the storage of a movable

Existence agent exist. Approaching fibers are thereby blown away and at an entrance into the

Storage location hindered. Fibers can also be made from one

Freewheeling gap to be blown out by a corresponding air flow. The display (s) and / or the safety actuator (s) are connected to the detection device. The

Safety device may further include a controller

respectively. This can be your own separate and

be hardware-based control. Alternatively, a

Control module possible, which in another control, e.g. in the control of the baler or in the

Plant control of a baling plant or the like.

is integrated. Such a control module may be formed by software and / or hardware. The

Detection device, the display and / or the safety actuator (s) may be connected to the controller In the subclaims further advantageous embodiments of the invention are given.

The invention is illustrated by way of example and schematically in the drawings. In detail show:

Safety device. The invention relates to a safety device (4) and a safety method for a discharge device (5) of a baler (2, 3). The invention also relates to a discharge device (5), which with a

Safety device (4) is equipped. The invention also includes a baler (2,3) with a

Discharge device (5) together with safety device (4) and a baling plant (1) with several such

Balers (2,3). The invention also relates to a process for the production of pressed bales.

Figures 1 and 2 show a baling plant (1) in which a plurality of balers (2, 3) are suitably arranged, e.g. in a row. In another embodiment, a single arrangement of a baler (2) is possible. The balers (2) are shown for clarity without their scaffolding.

The balers (2, 3) shown are interconnected e.g. similarly formed. The one or more times

existing balers (2,3) are each as

stationary baler trained. This differs from mobile balers, which are e.g. on

agricultural followers are arranged.

The one or more balers (2,3) are made for the production of high density pressed bales

provided and formed fed short cut fibers. The fibers are preferably synthetic fibers. They can be made of a plastic, e.g. Acrylic, polyester or the like consist. The fibers may be made of a uniform plastic or a mixture of materials

consist of different plastics.

The short cut fibers are made of long ones

Fiber strands, so-called tow produced. They are for this purpose, for example by means of a cutting device (not shown) cut off from the fiber strands in the desired and preferably constant length. Such short cut fibers are also referred to as staple fiber.

The fibers are suitably fed to the baler (s) (2,3) by means of a fiber supply (30), e.g. in an airflow passing through the canal

Fiber supply (30) flows. The fiber supply (30) may be connected to one or more balers (2,3).

The respective baler (2,3) has a fiber feed (6), with which the fibers are removed from the fiber supply (30) and introduced into the baler (2,3). The fiber feed (6) may e.g. be designed as a condenser, which separates the fibers from the air flow.

The balers (2,3) each have one

Pressing device (9) with which the supplied fibers in a preferably movable press box (not shown) to a pressed bale with high pressing force, e.g. of 500 tons, compacted and pressed. The pressing device (10) has for this purpose upper and lower stationary and / or moving press punches and a suitable, e.g. hydraulic, ram drive on.

The fibers are the pressing device (9) of the

preferably overhead fiber supply (6) via an upright shaft (7), a local discharge device (5) and a filling device (8) supplied. The

Discharge device (5) is e.g. in the shaft (7) and below the fiber feed (6). Below the

Discharge device (5) is the filling device (8)

arranged. This is preferably connected to the pressing device (9). The shaft (7) is a hopper in which the

supplied fibers or half of the discharge device (5) are dammed. The discharge (5) promotes the fibers controlled in the shaft (7) down to

Filling device (8). On the other hand, the discharge device (5) can let the air pass through the shaft (7). It can have the function of a rotary valve. The

Discharge device (5) will be described in more detail below.

The filling device (8) has e.g. a lying or diagonally arranged collecting shaft for from above

supplied fibers, which then transferred from the collecting shaft in the pressing device (9), in particular

be pushed over. In the filling device (8), the supplied fibers can be precompressed, e.g. through a slider. This can also provide for the further transport of the precompressed fibers in the pressing device (9). The filling device (8) may have a metering device and optionally a weighing device. As a result, the fibers can be supplied batchwise and with a defined amount or weight, wherein the pressed bales of a

predetermined batch number is produced.

The baler (2,3) may further each have their own or common packaging means (10) for the

Press bales exhibit. The high-density pressed bales can be suitably packed, e.g.

by means of a strapping and possibly a wrapping with a packaging film or the like .. In the shown

Baler (1) are several

Packaging devices (10) separated and possibly arranged in a higher number to the balers (2,3). The packed bales are from the

Packaging device (10) to a conveyor, e.g.

a carriage, a conveyor belt or the like, handed over for transport. The pressed bales are thereby using a

Transport device (11) of the respective baler (2,3) transported to a separately arranged packaging device (10). The transport device may e.g. with one along a traverse, e.g. hanging movable and rotatable transport fork are transported. To grasp the high-density pressing bale while maintaining the pressing pressure, the transport fork fork arms

which can be moved with high force relative to each other for closing and opening.

The discharge device (5) is shown in more detail in Figures 3 to 9. It has one or more moving ones

Discharge means (21,22,23) on. The or the discharge means (21,22,23) are preferably circumferentially movable. In the embodiment shown, the discharge means

(21,22,23) e.g. designed as a rotating cylindrical discharge rollers. Alternatively, another embodiment of dispensing means, e.g. as tapered rollers, circulating belts, rakes or the like. possible.

In the embodiment shown, three discharge means or discharge rollers (21, 22, 23) are arranged in a spatial triangle. Two discharge means (21,22,23) are on

the same height next to each other at the top and the third discharge means (23) arranged centrally below. Instead of Trippelanordnung shown can also be a

Tandem arrangement of e.g. the pair of upper discharge means (21, 22) or another arrangement with a different number of discharge means (21, 22, 23).

The discharge means (21, 22, 23), in particular discharge rollers, are provided with their longitudinal axis and their e.g. central

Movement axis arranged parallel to each other. Here are formed between the discharge (21,22,23) slots through which the fibers can be promoted. In the embodiment shown, the two upper rotate Discharge rollers (21,22) in opposite directions and convey the fibers through the central slot between them down to the lower discharge roller (23). The lower discharge means or the discharge roller (23) deflects the fibers supplied from above in the stream and distributes them laterally in the shaft (7). The lower discharge means (23) or the discharge roller can be left-handed or right-handed. The two upper discharge means (21,22) can move slower than the lower discharge means (23), in particular rotate. The discharge rollers shown each rotate about a central axis of rotation.

The discharge means (21,22,23) have shown in the

Embodiment in each case a controllable drive (26), in particular a roller drive. The drives (26) are e.g. all arranged on one side of the discharge means (21,22,23). At the other, opposite side there may be a synchronization (28) synchronizing the two upper discharge means (21, 22) with each other in their rotational speed, e.g. by a chain, a timing belt or the like .. The synchronization (28) can also be omitted.

As Figure 6 in cross-section and Figure 7 illustrate in longitudinal section, there are the discharge rollers shown

(21,22,23) each from a central shaft (24) or a shaft which is surrounded at a radial distance from a preferably concentric jacket (25). Shaft (24) and jacket (25) can be connected to each other by support discs (32).

The jacket (25) of the discharge means (21, 22, 23), in particular discharge rollers, can each engage on the outside

have suitable conveying element for the fibers. For the upper discharge rollers (21, 22), the conveying element is e.g. formed by several axial conveyor belts, the from

Protruding jacket (25) to the outside and in the circumferential direction on Sheath (25) are evenly distributed at a mutual distance. In the lower discharge roller (23) is the

Conveying means formed by a plurality of outwardly projecting pins, which are each arranged in axial rows on the jacket (25), wherein the rows are distributed in the circumferential direction at a distance evenly spaced on the jacket (25).

Other types of conveying elements, e.g. Shed, rake or the like. , are possible. These are e.g. for others, in particular ribbon-like, discharge advantageous.

The discharge device (5) also has a housing (19). This is formed like a shaft or like a ring and has an upper opening and a lower opening. The openings each connect to the shaft (7). The movable discharge means (21,22,23), in particular

Discharge rollers are each by means of a bearing (27), in particular a roller bearing, to the

mounted opposite end walls (20) of the housing (19). Here, e.g. the shafts or waves

(24) are rotatably mounted. At the end faces (20) are also the drives (26) and the possibly

opposite synchronization (28).

Between the discharge means or (21,22,23) and the frontally adjacent housing wall (20) in each case a freewheeling gap (29) is formed. This is due to an axial distance between the respective discharge (21,22,23), in particular its jacket (25), and the

Housing wall (20) formed and allows unimpeded relative movement of the respective discharge means (21,22,23) relative to the stationary housing wall (20). In another embodiment, a freewheeling gap (29) also at a mutual overlap between the front end of the discharge means (21,22,23), in particular its jacket

(25), and an undercut housing wall (20). The discharge device (5) conveys the fibers arranged in a pulp or a column above in the shaft (7) downwards through the said slots and distributes them in the lower region of the shaft (7). It is possible that fibers accumulate in the freewheeling gap (29) and / or in the region of the bearing (27) and connect to each other. As a result, a in Figure 7 on the jacket area

indicated fiber winding (31) arise. The freewheeling gap (29) is located in front of the bearing (27). Here, for example, first to form fiber accumulations and a filament winding (31).

The filament winding (31) can be in motion or

Direction of rotation at a discharge (21,22,23) extend. He can e.g. Close the freewheeling gap (29) at least in places. It can also form on the shaft (24) or the bearing (27) and may possibly also in the

Penetrate storage. Due to the prevailing movement and frictional heat, the fiber winding (31)

heat. Depending on the melting temperature and / or

Ignition temperature of the fibers can also lead to a melting and / or a final ignition of the fibers and the fiber winding.

The safety device (4) has a

Detection device (12), which is provided and designed for the detection of a winding of fibers on the discharge device (5). As a result, a detection method for detecting a winding formation is also carried out. The safety device (4) is the

Associated discharge device (4). The

Safety device (4), in particular the

Detection device (12) can be arranged on the discharge device (5) in a suitable manner, for example by mounting or integration. The safety device (4) can have further components (13, 14, 15), which are optionally arranged elsewhere. This will be explained below entered.

In the embodiment shown, the

Detection device (12) and the detection method is adapted to a winding formation of fibers on a

Freewheeling gap (29) and / or on a storage (27) of one or more discharge means (21,22,23) to

detect. In the embodiment, the

Detection of winding formation indirectly by detecting a temperature increase in the range of one

Freewheeling gap (29) and / or from a storage (27).

The detection device (12) has, according to FIGS. 8 and 9, a sensor system (17), which, e.g. for the indirect detection of a winding formation of fibers on the discharge device (5) is formed.

The sensor system (17) has one or more identical or different sensors (18). These are e.g. designed as thermal sensors. In the shown

Embodiment, a plurality of similar thermal sensors (18) are present. These are e.g. arranged on or in one or both frontal housing walls (20). The thermal sensors (18) are e.g. designed as a heat sensor, which convectively a temperature at the

Detect housing wall (20), which can be influenced by a winding of the fibers and in particular increased. A filament winding (31) can generate frictional heat, which leads to such a temperature increase on the housing wall (20).

The thermal sensors (18) are arranged in a suitable number and at a suitable location on the housing wall (20).

In this case, at least one thermal sensor (18) is located in the region of a freewheeling gap (29) and / or one

Storage (27). The emanating from a local winding heat and temperature increase can thus close be detected at the point of origin.

Figure 8 shows an end view of the housing wall (20) on the drive side, wherein the drives (26) not

are shown and only the shafts or shafts (24) and their bearings (27) on the housing wall (20) can be seen. Near the e.g. three bearings (27) each have a thermal sensor (18) is arranged.

Alternatively or additionally, one or more further thermal sensors (18) may be located on the housing wall (20), e.g. are arranged in the region of a freewheeling gap (29). In addition, more can

Thermosensors be arranged at other locations of the housing (19). With such other sensors can

Reference temperatures are taken at locations of the discharge device (5), which are not burdened by a winding formation. This can be e.g. the normal one

Operating temperature to be recorded.

Figure 9 shows a partially transparent front view of the other housing wall (20) with the only in parts

illustrated synchronizing device (28). Due to the partially transparent representation of the housing wall (20), the shafts or shafts (24) and the shells (25) of the discharge (21, 22, 23), in particular discharge rollers, visible. Here, the assignment of one or more sensors (18) in the region of one or more freewheeling gaps (29) can be seen in the cladding region.

The thermal sensors (18) can be arranged in any suitable manner on the housing wall (20) or parts thereof. They can be located, for example, on covering or bearing plates. They can be arranged as eg attached heat sensor on the outside of the housing wall (20) or one of its parts. In another embodiment, not shown, one or more, eg convective thermosensors (18) may be arranged on the discharge means or means (21, 22, 23). They can be located on the shaft (24) and / or on the jacket (25). They can be arranged close to the end face or the bearing (27) of shank (24) and / or sheath (25).

Except the embodiment shown and the

The aforementioned modification also makes possible other variants of the sensor system (17) and its one or more identical or different sensors (18). A thermal sensor may e.g. be designed as strain gauges, the thermal expansions at a suitable location of the housing (19) and / or a discharge means (21,22,23) receives.

The safety device (4) has the exception

Detection device (12) further said components. This can e.g. according to Figures 1 and 2, a controller (13), a display (14) and a safety actuator (15). The display (14) and the safety actuator (15) may be present alternatively or in combination. They can also be arranged individually or multiple times. The detection device (12), the display (14) and the safety actuator (15) can be connected to the schematically indicated control (13).

When the sensor system (17), in particular its one or more sensors (18), a temperature increase and exceeding a defined and predetermined

Signaling trip temperature, the

Safety device (4), in particular their control (13), take a suitable safety measure. The temperature or temperature increase can be measured directly or detected indirectly, eg by thermal expansion The triggering temperature can be fiber-specific. It can be between a normal operating temperature at the

Discharge device (5) and a fiber-specific higher limit temperature, from which the respective fiber melts and / or ignited. A normal one

Operating temperature may e.g. at 100 ° C, wherein the higher limit temperature for melting or igniting the fiber is about 300 ° C. The triggering temperature is between these two temperatures. It can be chosen so that on the one hand the detection security is ensured for a winding formation and on the other hand there is still a sufficient distance from the said limit temperature for melting and / or igniting the respective type of fiber. Such a triggering temperature may e.g. at about 200 ° C. At such a triggering temperature, winding may be timely before melting

and / or igniting the fibers in the filament winding (31)

be detected. For the determination of the current and normal operating temperature, the aforementioned other reference thermal sensors can be used.

The display (14) can deliver a warning signal in any way. This can be done optically, e.g. by a warning light, and / or acoustically, e.g. by a siren, and / or haptic, e.g. by a vibration, done. The display (14) may be arranged on the discharge device (5) and / or elsewhere of the baler (2,3) and / or on a control station and / or at another location.

The single or multiple safety actuator (15) may e.g. an emergency switch (not shown). The controller (13) then turns off the respective baler (2, 3) via the emergency switch in response to a detected winding formation. The filament winding (31) can at

A safety actuator (15) may alternatively or additionally be arranged according to FIG. 1 on the fiber feed (6) and may be designed, for example, as a changeover switch (16). Such a switch (16) can on the one hand the access of

Block fibers from the fiber supply (30) into the fiber feed (6). A switch (16) may alternatively or additionally a redundant switching function for the

Fiber stream in the fiber supply (30) have. He can redirect this fiber stream to another, in standby or already running baler (3).

The safety device (4) can also have on another side a blowing device which blows away individual fibers or fiber accumulations preventively from the region of a freewheeling gap (29). This extra

Components or safety measures of

Safety device (4) are not shown for clarity.

Modifications of the embodiment shown and the aforementioned variants are in different ways

possible. In particular, their features can be combined or interchanged in any way.

The baler (2,3) may have a different configuration and arrangement. It does not have to include all of the aforementioned components. On a packaging device (10) and a transport device (11) of the type shown can be dispensed with alternatively. A packaging of the press bale can also take place in the pressing device (9). In the embodiment shown, the pressing device

(9) arranged standing. It can alternatively be arranged horizontally. In a further modification, the filling device (8) can be dispensed with or designed in another way. Likewise, the
