Description

The invention relates to a control module, a holding section therefor and a textile machine equipped with such a holding section.

Textile machines usually have their own controls. For example, these are inserted next to one another in modules in a housing of the textile machine. The problem here is the cooling, in particular of the electronic (power) components of the controls. It is known to cool the control cabinet, for example of a route, by means of external ventilation. For this purpose, a fan draws in ambient air through a corresponding filter mat and blows it into the interior of the control cabinet. The warm air exits through a corresponding outlet opening, which is also provided with a filter mat. It is disadvantageous that, despite filter mats, air containing fine dust can enter the control cabinet, which can have a negative effect on the electronic components. In addition, the filter mats are maintenance points that clog up if maintenance is not carried out and can therefore lead to an increased cabinet temperature. This in turn adversely affects the life of the electronic components. Built-in control modules, for example in the form of servo modules as main power consumers, also have internal small fans that cool the respective module to a minimum in the warm cabinet environment. This makes the modules more complex, which has a negative impact on production costs.

Solutions are also known in which a profile provided with cooling fins is preferably cooled from aluminum by means of an external air flow. The electronic components are attached to this profile and cooled via the surface contact. However, this fastening point is problematic, since the heat conduction does not function properly here due to thermal deformations or damage to the surfaces. In order to achieve usable results, thermal pastes are used, which makes assembly difficult.

The object of the invention is to counter the aforementioned disadvantages.

This object is achieved by the subject matter of the independent claims. Advantageous further developments are specified in the subclaims.

A control module according to the invention has an associated operating section and a first fastening section on at least one side. The operating section includes an arrangement of electronic components and a cooling section. The cooling section includes a heat transfer section made of thermally conductive material, which contacts the electronic components on their heat emission side. The heat emission side can be the side that faces away from one side of the control module. In addition, the cooling section includes a heat dissipation section. The heat dissipation section is arranged on a side facing away from the electronic components or at least one side of the operating section in such a way that the heat dissipation section is able to dissipate heat from the heat transfer section to the outside with respect to the control module. The first fastening section is designed and configured on at least one edge of the control module that surrounds the at least one side, and is designed to be sealingly attached to a holding section of a textile machine. This enables the control module to be used as a partition at the same time. In addition, this means that the one side of the control module, the other, opposite side is not subjected to cooling, which offers advantages in the flow around the heat dissipation section. That is, the control modules as main power consumers are designed and arranged in such a way that they can be cooled directly by an external air flow outside a control cabinet. This eliminates the need for cabinet ventilation and the associated disadvantages are eliminated. In addition, the design of the control modules is simplified and the cooling of the usually temperature-sensitive electronic components is significantly more efficient. In addition, the cooling section forms an integral part of the control module, so that time-consuming assembly with thermal paste is not necessary. The control module can also be arranged outside a room which is provided for cooling, that is to say can continue to be cooled by means of an external air flow. There is no need for cabinet ventilation and the associated disadvantages can be avoided. In addition, the design of the control module is simplified and the cooling of its electronic components is significantly more efficient. Due to the fact that it is no longer necessary to apply thermal paste when assembling the control modules, a direct coupling between electronic components and the cooling section can be achieved ex works.

Preferably, a surface of the cooling section facing away from one side is designed to be sealingly attached to the holding section of the textile machine. That is, the cooling section takes on another function, which keeps the structure simple.

The heat emission side preferably runs essentially perpendicular to a circuit board side, on which the electronic components are arranged. This enables a maximum cooling surface, which means that air can be circulated at a low speed and thus saves energy, if not without a fan. In addition, this enables control of the cooling air flow and thus optimal cooling.

In each of the aforementioned control modules, the electronic components are preferably attached to the heat transfer section in such a way that their heat release side contacts the heat transfer section. This ensures optimal heat dissipation from the components to be cooled.

The cooling section preferably has at least one fan. The fan or ventilator is arranged and set up to dissipate heat from the heat dissipation section and the other control module. This dissipates the heat from the components to the outside. It is therefore an active control module cooling.

This control module also has or is coupled to a control circuit. The control circuit is set up to operate the at least one fan so that it dissipates the heat from the other control module. This enables controlled heat dissipation, particularly from an energy point of view. It is therefore a regulated or adaptable control module cooling.

The electronic components of the aforementioned control modules preferably comprise connection elements. The heat dissipation side can therefore be different from that of the electrical connection of the control module. This means that if the fan is present, it can continue to be operated even if the control module is (temporarily) disconnected. This is particularly advantageous if several control modules are arranged.

The heat dissipation section of each of the aforementioned control modules preferably has cooling fins. Due to their large heat dissipation area, these offer a very high cooling capacity, possibly passively, i.e. without a fan. For this purpose, the control module can be equipped with a modified aluminum heat sink.

The cooling fins are preferably formed parallel to one another. This enables the optimal alignment with respect to a heat emission air flow.

Each of the control modules can also have an associated operating section on a side opposite and facing away from one another.

The fastening section of each of the aforementioned control modules preferably has fastening openings which extend transversely to the at least one side. This enables the control module to be attached to a wall with simple means such as screws.

Each of the aforementioned control modules can be designed as a servo module, supply unit, for example for supplying energy to a textile machine and / or as a converter. The invention can therefore be used very universally.

A holding section according to the invention has a through opening. The through opening is designed to accommodate an associated one of the aforementioned control modules according to one of the preceding claims, apart from the first fastening section, in such a way that one side and an opposite and opposite side of the control module point in the direction of two mutually opposite sides of the holding section. The holding section further comprises a second fastening section belonging to the through opening. The second fastening section is designed to hold the first fastening section of the associated control module in a sealing manner. This creates a modular structure that can be used as a whole in a textile machine. That is, the control module (s) can be installed and connected outside the textile machine.

The second fastening section preferably at least partially surrounds the through opening and has a bearing surface for the first fastening section of the associated control module. This support surface therefore forms a support for the control module and can also be designed such that the control module is simultaneously positioned for attachment when it is placed on it. This simplifies assembly.

The second fastening section of the aforementioned holding sections preferably has fastening openings, each of which is aligned with an associated one of the fastening openings of the associated control module. The respective control module can thus be attached to the holding section in a simple manner by means of screws or locking means.

A textile machine according to the invention has an air circulation space. A wall section of the textile machine separates the air circulation space from other sections of the Textile machine. In addition, the textile machine comprises one of the aforementioned holding sections and at least one associated one of the aforementioned control modules. The at least one control module is attached to the holding section such that one side of the associated control module faces the air circulation space. This means that an existing fan (for example, for removing fiber waste) can also be used to cool the respective control module. In addition, the control module also partially takes over the spatial separation between the air circulation space and the space in which the electronic components are arranged. Therefore, no fiber material can get into this area and possibly damage the electronic components or impair their operation, for example due to reduced heat dissipation. This enables the outwardly projecting cooling fins of the control module (s) to be inserted into the air circulation space as a separate air duct through a partition wall, for example designed as a control cabinet rear wall. An air flow for cooling the control module (s) is conducted in the air circulation space and can advantageously be generated by a single, large axial fan. In addition, the air volume flow can be increased, which enables very efficient cooling. It is no longer necessary to ventilate the room in which the electronic components of the control module (s) are arranged. This room can therefore be made absolutely dust-tight. This eliminates the need for filter mats. Internal fans for the respective control module may no longer be required.

The wall section preferably has a plurality of the aforementioned holding sections. On each holding section, to which no control module is attached, a sealing section is attached or designed such that (instead of a control module) it closes the passage opening of the respective holding section. The simplest form is a blind plate, as is known from the PC field, with a preferably all-round seal. That is, the sealing section is preferably formed by means of a wall element which is designed to be breakable on the other wall section or is releasably attached to the first fastening section of the respective holding section.

The air circulation space of each of the aforementioned textile machines is preferably part of an extraction system of the textile machine. Existing parts of the textile machine are therefore used to cool the control module (s) additionally.

In each of the aforementioned textile machines, if a control module is provided with cooling fins, this control module and the associated holding section can be designed such that the cooling fins of the control module extend along an air flow direction of the textile machine in the region of the cooling fins. This reduces the risk that fiber material will accumulate on the cooling fins and thus impair the cooling performance.

The cooling section of a control module in each of the aforementioned textile machines is preferably designed to protrude from the holding section. That is, the cooling section protrudes into the air circulation space, so that no changes in the air flow are necessary on the part of the other textile machine.

Each of the aforementioned textile machines preferably has a closed chamber. The chamber is delimited on one side by the wall section of a respective holding section and on another side by a wall of the textile machine. The wall is formed at least in sections from thermally conductive material. The textile machine is thus able to passively dissipate heat from the electronic control module (s) independently of a possible fan.

This wall preferably forms an outer wall of the textile machine. This effectively transfers the heat to the outside of the textile machine.

1 shows an arrangement 1 with a gate 2nd and a downstream route 100 in a usual arrangement.

The gate 2nd is constructed in a known manner and is not described further.

The distance 100 has, among other things, a can depositing device on the output side 140 on. The can deposit device 140 includes a can rail in the example shown 141 for the full cans and a preferably powered can run 142 , the empty cans are moved into the actual can changer. The can changer has, for example, a can slide in a known manner 143 on. To the side of the track 100 there is an operating platform 102 . Here at one end of the operating platform 102 there is an operator terminal 101 . There is also a drafting hood 104 recognizable that a stretch section 103 covers in a known manner. There is a door on a front here 105 , behind which is exemplified the electronics of the route 100 located.

Between drafting hood 104 and door 105 is a base, for example, for receiving or holding the components of the stretching section 103 like drive and drafting rollers arranged. The base is in the example shown by means of a support plate 106 educated.

2nd shows the route 100 in several perspective individual views. The parts of the route not relevant to the invention 100 are omitted.

The support plate 106 has a circular through opening 106a on, in the turntable of the can not shown 140 the way 100 freely rotatable is included.

Below the support plate 106 there are preferably two frames on both sides 107 that at the respective in 2a External long side by means of an associated door 105 are closed.

An example is between the two frames 107 a wall section 108 provided of an opening 113 having. This opening 113 connects the surroundings of the route 100 Air technology with a partially recognizable screen mesh 109 .

The support plate 106 includes next to the through opening 106a two additional through openings as an example 106b , 106c .

The passage opening 106b connects the space above the support plate 106 , in which the stretching section is exemplary 103 is arranged with an underlying cavity 117b .

The screen mesh 109 separates another cavity, not shown here 117a from the room in which the opening 113 is arranged.

The passage opening 106c connects the space above the support plate 106 , in the example of the drive elements of the drafting system 103 are arranged with an underlying cavity 117e .

2 B shows the route 100 from the bottom.

The cavity, also not shown here 117a is to the bottom of the range 100 towards a wall section 121 limited. Below the wall section 121 is preferably one to the bottom of the range 100 open cavity 117d educated. In the cavity 117d are a fan wheel 111 with associated drive motor 110 arranged in such a way that, during operation, air comes out of the cavity that is not visible here 117e towards the bottom of the route 100 is suctioned off.

Apart from that, on the wall section 121 an opening 112 be provided with a ventilation grille and / or a filter mat to allow air to pass from the surroundings to the cavity 117a to enable.

2c shows the route 100 from the perspective of in 2 B upward facing door 105 in a view that looks into the cavity 117a releases, with some elements omitted from the illustration.

The cavity 117a is completely enclosed by the two frames 107 , of which only the rear one is shown, wall sections 121 - 123 and the support plate 106 .

The cavity 117e ends with a back at the front edges of the wall section 121 , a wall section 123 and a wall section 122 in which the screen mesh 109 is arranged.

The wall section 123 separates the cavity 117a from a cavity 117b .

The cavity too 117b is completely enclosed by the two frames 107 , of which only the rear one is shown, wall sections 108 , 123 , 125 and the support plate 106 .

Exemplarily on the partition 123 is a fan 115 attached so that it passes through the mesh 109 air from the surroundings through a through opening (not visible here) in the wall section 123 through it largely free of dirt into the cavity 117b sucks in. This sucked in air leaves the cavity 117b through the through opening 106b . In the cavity 117b are cooling sections 131 control modules explained in more detail later 130 as well as rib elements 114 arranged, which are cooled due to the intake air.

The air that flows through the passage opening 106b flows into the drafting room, passes through other openings in the route 100 in the nearby areas. In addition, this air can pass through the through opening 106c in the cavity 117e pour in and the cavity 117e leave through a filter mat, not shown. The filter mat is provided, for example to retain fiber material. Ideally, there is a single air flow through the route 100 through that of both components of the route 100 cools as well as unwanted material (dirt, detached fibers, ...) from the track 100 away.

Alternatively, air passes through the through hole 106c from the cavity 117e dissipated.

The rear frame 107 covers at its the cavity 117b facing side a partition 120 on.

2d shows the cavity 117b in greater detail. The cooling sections 131 include seven cooling fins, for example 131a . The associated control modules, not shown here 130 are in the example shown by a plate 160 inserted through and with screws and nuts 3rd on the plate 160 fixed. The plate 160 is on the partition 120 attached to the cavity 117b locks back here. An emergency stop button 159 is on a wall section 124 attached to the cavity 117b closes here to the left.

3a shows the frame 107 that the cavity 117b limited, in the cutout with the partition 120 in a modified form.

The plate is missing as an example 160 , and the control modules 130 are directly on the partition 120 appropriate. In the cavity 117c are the control modules 130 arranged with their electronic power components not designated. Each control module has 130 over a cooling section 131 that is in the cavity 117b located. This means that every control module 130 so through the partition 120 is arranged that the cooling section 131 in the cavity 117b is arranged. The cooling sections are preferably 131 with their cooling fins 131a at the free ends with an air duct section 116 provided so that duct-like air flow ducts result. This enables the chimney effect to be exploited. In order to increase the cooling capacity, the air duct section comprises 116 an angled wall section on one edge and possibly also on the opposite edge 116a that is parallel to the cooling fins 131a extends and is arranged at a distance from these.

Alternatively, the air duct section is missing 116 so the ribs 131a free in the cavity 117b protrude.

The air duct section 116 is exemplarily designed so that the fan 115 outside the cooling sections 131 is arranged. The ventilator 115 can also analog PC components directly above the cooling sections 131 be arranged so that it air directly against the tips of the cooling fins 131a presses.

Any control module 130 features in the cavity 117c preferably via a housing 132 in which the power components are arranged. There are also screws 4th shown with an associated mother 3rd the respective control module 130 on the partition 160 fix.

The housing 132 preferably has ventilation slots on both ends 133 to the passage of air through the housing 132 to allow through.

To increase the cooling capacity is located between two adjacent cooling sections 131 one additional rib element each 114 .

3b shows the representation of 3a from the perspective of the cavity 117c from the in 3a in a modification to the rear-facing side. The partition is missing for the sake of illustration 120 , and the control modules 130 are on the plate 160 appropriate.

The plate 160 has wall sections on the outer circumference 161 on. As can be seen, the control modules 130 preferably all additionally one in the associated housing 132 arranged fans 135 that additionally cools the electrical components. This means that the heat doesn't just go through the cooling sections 131 but also about the fans 135 can be dissipated. The ventilation slots 133 facilitate the air flow through the housing 132 of the respective control module 130 through it.

4th shows the plate 160 for attaching the control modules 130 in an exploded view in greater detail.

Only two control modules arranged side by side are exemplary 130 pictured. The plate 160 has a wall section 162 on, in the example shown, preferably only a single through opening 164 for pushing through the control modules 130 having. To improve heat dissipation in the cavity 117b is located between two adjacent control modules 130 one rib element each 114 . Every rib element 114 has two mounting holes here 114a into which a respective screw 5 through a respective mounting opening 166 in the Wall section 162 is screwed through and thus the rib element 114 on the plate 160 fixed. The fixation takes place from the cavity 117b facing side, so that the control modules 130 even after attaching the rib sections 114 can be fixed to the wall section. The assembly order is completely irrelevant.

The control modules 130 include tabs in the example shown 138 , the through holes 138a include. The screws 4th are through an associated pair of through holes 138a and 165 (in the plate 160 ) passed with an associated mother 3rd on the opposite side of the wall section 162 screwed and fix the respective control module 130 .

Of course, all other types of fastenings such as locking and the like are possible.

In the example shown there are also earth connections 137 which is a housing 132 via an earth line 136 with the wall section 162 connect. So the control modules 130 , which are designed, for example, as servo controls, are correspondingly electrically secured.

There is also a cable duct 163 shown, through which, for example, sensor lines are passed.

The control modules 130 are sealing on the plate 160 or the partition 120 put on. In the example shown, the sealing is carried out by means of a surface 131b that of the plate 160 is facing the cooling section 131 a surrounds and on the plate 160 comes to rest. Alternatively or additionally, the seal can be made using the plate 160 facing, not designated areas of at least one tab 138 respectively.

5 shows the part of the route 100 with the electronic components of the control electronics of the route 100 in two views.

As in 5a the cavity can be seen 117c , apart from the side open to the front here, completely enclosed. This open side is from the door, not shown here 5 also closed, so that there is a completely enclosed cavity 117c forms.

In the support plate 106 are through openings 106d in place to make pipes dustproof from the stretch section 103 facing, here top of the support plate 106 in the cavity 117c lead in.

The lines can be laid, for example, through a foam element, on the one hand, the respective passage opening 106d seals and on the other hand mechanical protection of the lead-throughs in relation to the respective passage opening 106d offers. The foam seal can be formed in two parts, so that the lines can be easily inserted into the foam seal.

5b shows the cavity 117c in a sectional view along a plane that extends essentially along the longitudinal extent of the support plate 106 perpendicular to their top in 5a extends in such a way that the in 5a border shown in 5a forward-facing, open side of the cavity 117c is not visible.

In the cavity 117c is an example of a circuit board 8th shown on the various functional elements of the control electronics of the route 100 are arranged. In the example shown, the functional elements comprise a transformer 151 , a main controller 152 , a monitoring element 153 , a frequency converter 154 , a measuring section 155 , a line filter 156 , a throttle element 157 and a fuse section 158 .

The functional elements are preferably 152 , 154 and 155 each with a fan 6 provided that the respective functional element 152 , 154 respectively. 155 actively cools. The main control 152 has two levels, with a space in between 152a is formed, in which the associated fan 6 either blowing air in or sucking it out.

The frequency converter 154 is on his the circuit board 8th facing side with a heat sink 7 Mistake. The ventilator 6 is on the front of the frequency converter 154 arranged.

The measurement section 155 is exemplarily provided with active cooling, which essentially consists of a fan 6 and a heat sink located below 7 consists.

The electrical connections between the functional elements 151 - 158 and other electronic components such as capacitors are not shown.

In contrast to 5a are just three control modules 130 on the corresponding plate 160 arranged, which in turn on the partition 120 is fastened, for example, by means of screwing. The plate 160 is by means of tab-like sections here 167 with the board 8th at least mechanically connected so that the board 8th is kept safe. The circuit board is alternative or additional 8th on the partition 120 attached itself.

The left two places for control modules 130 are by means of cover plates 9 at least sealed dustproof. The left cover plate 9 is shaped like a cover plate of a PC case and only by means of a screw 4th here on the plate 160 fixed. The cover plate located on the right 9 is by means of two screws 4th also exemplary on the plate 160 fixed.

In the case 132 each control module 130 an unmarked operating section is added. The operating section includes the electronic circuitry of the control module 130 . The operating section is preferably designed as a module and as a whole in the housing 132 used.

Power elements of the operating section by the fan 135 alone cannot be cooled, stand with the cooling section 131 heat transfer in contact. This makes it possible to transfer excess heat into the cavity 117b to deliver.

The cooling section 131 over its cooling fins 131a be cooled passively. However, it is also conceivable to provide a fan, so that (additional) active cooling of the cooling section 131 and thus also the control module 130 arises.

The one in the room 117c heat generated is so low that it passes over the walls of the frame 107 and the associated door 105 to the surroundings of the route 100 can be delivered in sufficient measure.

The invention is not limited to the embodiments described above.

For example, the frequency converter could also 154 be designed so that it with its heat sink 7 in the cavity 117b protrudes. The main control 152 communicates with the functional elements 130 , 151 , 153 - 159 other controls.

The separation of the cavities according to the invention 117b , 117c from each other can be applied to any other machine in the spinning mill, provided that a cavity is provided in which the control electronics are accommodated and in which there is or can be a separate air flow which is used, for example, to extract undesired (fiber) material . This applies, for example, to unregulated draw frames, drafting systems on combers or belt winders, the combed area of the comber itself, cleaners, cards, foreign part separators and spinning machines.

The control modules 130 and, if present, the cover plate or covers 9 are sealing on the plate 160 or the partition 120 put on. Sealing can take place, for example, by means of a seal, which is located at corresponding points on the plate 160 or the partition 120 and / or on the element to be attached 9 , 130 is attached or trained.

The passage opening 164 can only be used to hold a single control module 130 or any other component to be cooled, such as the main controller 152 be trained. Accordingly, on the partition 120 for example several plates 160 be provided.

Alternatively or additionally, the partition can 120 contain one or more, separate through openings that function as the through opening 164 has or have. Also is a combination of such a partition 120 with one or more plates 160 conceivable.

The invention therefore offers a simple and effective possibility of being able to cool control electronics and to accommodate their electronic functional elements in a hermetically sealed cavity, so that there is no dust deposit which could adversely affect the functioning of the control electronics.
