[0031] Each rotary electric actuator 1111 of the first group 110 and of the second group 120 comprises a rotary motor, a cable box 1110 fixed to the rotary motor, an inlet pipe 1112 and an outlet pipe 1113 fluidically connected on one side to an internal coolant circuit of the rotary motor and on the other side to a distribution manifold 14, the internal coolant circuit in the rotary motor being known in the state of the art of the technique.

[0032] Each cable box 1110 of the rotary electric actuators of the first group 110 and of the second group 120 is electrically connected to the shedder control cabinet 2 which provides the energy, transmits the set points to the electric actuators 1111 and controls the operation of the shedder 1 according to the stored weaving program and the parameters provided by the weaver. The cable boxes 1110 are inserted into the electronic unit 63 of the control cabinet through cables which pass through two connection bushings arranged at the bottom of the right panel 204 of the shedder control cabinet 2.

[0033] The distribution manifold 14 is arranged on the mounting plate 11 of the shedding machine 1. The distribution manifold 14 comprises outlet hoses connected to the inlet channels 231 of the shedding machine control cabinet, wherein each outlet pipe 1113 of the first 110 and second 120 set of actuators is connected to an outlet hose. The distribution manifold 14 comprises inlet hoses connected to the outlet channels 236 of the shedding machine control cabinet, wherein each inlet pipe 1112 of the first 110 and second 120 set of rotary electric actuators 1111 is connected to an inlet hose.

[0034] The distribution manifold 14 supplies cold coolant to the first 110 and second 120 set of rotary electric actuators 1111 and collects hot coolant from the set of rotary electric actuators 1111 to direct it back to the shedding machine control cabinet 2.

[0035] The shedding machine control cabinet 2 comprises a mechanical structure made of light metal, such as made of steel sheet.

[0036] The cabinet structure 2 comprises a front panel 201, a rear panel 202, a left panel 203 and a right panel 204 joining the rear and front panels at the cabinet body connections, a lower panel 200 and an upper panel 205, which define a chamber 23 of the shedding machine control cabinet 2, which contains an internal space. Each of the front panel 201 and the rear panel 202 is fixed with screws to two of the four upright members extending vertically between the lower panel 200 and the upper panel 205. The right panel 204 and the left panel 203 are pivotally mounted on two respective upright members as pivoting doors.

[0037] Three pairs of opposite crossbeams 291, 292, 293, 294, 295, 296 are mounted on the upright members parallel to the X axis and define, in pairs, horizontal and equidistant median, upper and lower planes. Each crossbeam 291, 292, 293, 294, 295, 296 has an L-shaped cross section so that it comprises a track portion in the width of the shedding machine control cabinet 2.

[0038] The front panel 201 is integrally formed with a bottom grate 2011, an upper grate 2013 and an intermediate grate 2012, which are vertically spaced apart along the front panel 201 and respectively face a bottom rectangular filter 2014, an upper rectangular filter 2016 and an intermediate rectangular filter 2015 covering the grates entirely. The bottom grate 2011, the intermediate grate 2012 and the upper grate 2013 jointly define an inlet opening of the shedding machine control cabinet 2.

[0039] The cabinet 2 comprises two handles mounted on two adjacent upright members of the cabinet structure, configured to move and orient the shedding machine control cabinet 2 on its wheels with respect to the loom W.

[0040] The heat exchanger 21 comprises a body and cooling fins made of metal. The internal circuit guides the coolant and can evacuate the heat by thermal conduction. The heat exchanger 21 comprises fluid connection channels forming an internal circuit extending between an input port 211 and an output port 212 of the heat exchanger. The heat exchanger 21 is contained in a global envelope which more or less occupies a rectangular recess 2051 of the upper panel 205 in the horizontal plane.

[0041] The rectangular recess 2051 defines an outlet opening 2051 of the shed control cabinet 2. The body defines a gap allowing air to pass through the heat exchanger between the chamber 23 and the main fan 222. The main fan 222 comprises a grille 221.

[0042] An L-shaped connector is mounted on the input port 211 of the heat exchanger 21 and is connected to a second flexible tube 232 which passes through the upper panel 205 and is guided in a second guide channel 2024 at the junction of the right panel 203 and the front panel 201. The second flexible tube 232 is held between the crossbeams 291, 292, 293 and the front panel 201 and enters a bottom collar of the right panel which guides the second flexible tube 231 to the outside of the shed control cabinet 2. Another L-shaped connector is mounted on the output port 212 of the heat exchanger 21, opposite the input port 232, and is connected to a first connection flexible tube 233. The first connection flexible tube 233 is mounted on a coolant tank 214 which is mounted on a tank support 215 fixed to the upper panel 205. The lower side of the coolant tank 214 is connected to a first flexible tube 234 which is guided vertically in a first guide channel 2035 at the junction of the left panel 204 and the rear panel 202 and enters the inlet of a coolant circulator 2323 fixed to the lower panel 200. The outlet of the coolant circulator 2323 is connected to an outlet channel 236 of the shed control cabinet 2.

[0043] A first circuit C is then defined between the inlet channel 231 and the outlet channel 236, which is configured to draw hot coolant from the inlet channel 231, cool it by passing through the heat exchanger and supply the cooled coolant to the outlet channel 236.

[0044] A funnel 223 is provided above the heat exchanger 21. It comprises a four- walled portion and a cylindrical portion around a vertical axis Z2 and is connected to the four-walled portion by a flat portion. The funnel 223 fits with the global envelope of the heat exchanger 21 on the lower side and of the main fan 221 on the upper side, so that the air from the chamber 23 of the shed control cabinet 2 is guided through the heat exchanger 21 by the main fan 222 without loss of airflow, which is efficient for heat exchange.

[0045] The shed control cabinet 2 has dimensions of about 650 mm in depth with respect to the X axis, about 600 cm in width with respect to the Y axis and about 1700 mm in height with respect to the Z axis.

[0046] The shed machine control cabinet 2 comprises a first rack unit 51, a second rack unit 52 and a third rack unit 53, which are staggered along their height and are mounted horizontally on rails parallel to the front panel 201. The rails are integral with the crossbeams 291, 292, 293, 294, 295, 296. The rack units 51, 52, 53 can slide on the rails to facilitate the removal of the rack units 51, 52 and 53 from the shed machine control cabinet 2. The right panel 204 and the left panel 203 are mounted on door hinges and can be opened and closed like a door. The front panel 201 and the rear panel 202 can be removed by disassembling the assembly screws, which facilitates maintenance operations around the rack units 51, 52, 53 and access to the electronic components.

[0047] Each of the first rack unit 51, the second rack unit 52 and the third rack unit 53 comprises a base plate 65, integral with two sliding blocks, configured to slide on the L-shaped rails 291, 294 of the shed machine control cabinet 2 and to house the electronic circuit 64.

[0048] Each base plate 65 comprises a heat-conducting structure, similar to that made of metal, which houses, on the front side of the base plate 65, the power supply unit 61 and, on the rear side of the base plate 65, the processing unit 62, fixed with heat-conducting means and integrated with some auxiliary ventilation means.

[0049] The power supply unit 61 comprises two high-capacity capacitors and electrical components for converting the power supply from a specified voltage level to another different voltage level to power the rotary electric actuators 1111.

[0050] The processing unit 62 comprises an IGBT card, embedded with a CPU central processing unit, for controlling the rotary electric actuators 1111 to reach the angular position according to the determined set point and to generate the current in the rotary electric machines.

[0051] Each base plate houses six actuator controllers 63. The power supply unit 61 and the processing unit 62 comprise electrical components that provide energy and control for the six rotary electric machines.

[0052] The auxiliary ventilation system for each rack 51, 52, and 53 includes a heat sink fixed to the front side of the baseplate 65 and below the power supply unit 61, allowing the heat sink to draw heat from the heat-conducting structure. The auxiliary ventilation system also includes a first fan 68 and a second fan 66. The first fan 68 faces the grille 2013 of the front panel 201, blowing air into the heat sink. The second fan 66, similar to the air assembly fan, blows air directly onto some of the electronic components of the power supply unit in a direction parallel to the Y axis. The auxiliary ventilation system includes three additional auxiliary fans 69, fixed to the baseplate 65 below the control unit 62 and distributed across the width of the control cabinet. They face the grille 2013 and blow air primarily in a direction parallel to the Y axis. This applies equally to the structure and function of rack units 51 and 52.

[0053] The base plates 65 extend within their own horizontal planes, rather than extending across the entire width and depth of the control cabinet, so that the air gaps define the lateral gaps between the frame units 51, 52, 53 and the panels of the shuttle machine control cabinet 2, forming a channel for air to flow upward and toward the heat exchanger 21.

[0054] The control cabinet also houses an electronic unit 70 with safety components installed, such as some fuses and the main disconnect switch 71 of the shed machine 1. The shed machine control cabinet 2 also houses an electronic unit, not shown, for supplying energy to the main fan 221 and the coolant circulator 2323.

[0055] During operation of the loom W, the shed machine 1 controls the angular movement of the rotary motor of the electric actuator 1111 according to the weaving program and moves the output lever 40 accordingly, which causes the shed machine 1 to lift and lower the corresponding heald frame to form a warp shed.

[0056] During operation of the loom W, the main fan 222 operates to draw air from the outside into the interior space of the shed machine control cabinet 2. Dust in the ambient air is retained by the filters 2014, 2015, and 2016, while air at ambient temperature is drawn into the chamber 23. The main fan 222 is maintained at a predetermined speed to optimize the performance of the required airflow A. The electrical components of the electronic unit 64 dissipate heat into the chamber 23 and the base plate 65 through thermal conduction.

[0057] The auxiliary fan 69 is also operating to accelerate the airflow A inside the chamber 23 and to cool the substrate 65. The coolant circulator 2323 is operating during the loom operation and drives the coolant through the first circuit C by expelling the coolant from the outlet channel 236 of the control cabinet 2 into the distribution manifold 14 of the shed machine 1. The coolant passes through the rotary electric motors of the two groups of actuators, collecting the heat generated by the motor operation. The coolant is collected by the distribution manifold 14 and is directed to the inlet channel 231 of the control cabinet 2. The coolant is directed upwards by the first hose 232 of the first circuit C and rises up to the heat exchanger input 211. The coolant is directed through the heat exchanger 21 by the channels contained in the wings of the heat exchanger 21. The main fan 222 sucks air from the chamber 23 of the shed machine control cabinet 2, which flows vertically through the heat exchanger 21 and collects heat from the coolant, thus cooling the coolant and being discharged into the first connection hose 233 and then into the coolant tank 214. The coolant is sucked directly into the second hose 234 and reaches the coolant circulator 2323. The coolant is discharged by the coolant circulator 2323 into the outlet hose 235 and outlet channel 236. The coolant circulates in a closed circuit between the shed machine 1 and the shed machine control cabinet 2 and is kept by the coolant circulator 2323 at a predetermined debit to maximize the efficiency of the required heat exchange.

[0058] In the maintenance configuration, the shed machine control cabinet 2 can be moved on its wheels and handled by the handle. The filters 214, 215, 216 are easily accessible and can be easily removed from the front panels for cleaning operations or replacement. The panels 201, 202, 203, 204 can be opened to allow the operator to access the chamber 23 and the electronic unit 64.

[0059] In an alternative, the shed machine control cabinet 2 operates a first coolant that can exchange heat through an auxiliary heat exchanger, directing another second coolant to cool the rotary electric actuators 1111.

[0060] In an alternative, the shed machine 2 is a dobby machine and the coolant from the control cabinet is directed to the oil-water exchanger of the shed machine that cools the oil flowing into the shed machine.

[0061] In an alternative, the combination of pump and coolant tank can replace the coolant circulator 2323 and the coolant tank 214.

[0062] In an alternative, sealing means can be added between the panels 201, 202, 203, 204, 205 to tightly seal the chamber 23.

[0063] The shedding machine control cabinet 2 can also be operated using more or less than sixteen rotary electric actuators 1111. Advantageously, the shedding machine control cabinet 2 is modular and can use one, two or three rack units and place them in the chamber 23.

[0064] The shedding machine control cabinet 2 can use any type of coolant, such as water, glycol or oil.

[0065] The shedding machine 1 can operate with the coolant circulating in the rotary electric actuators 1111 in turn, without the distribution manifold 14 shown.

[0066] The shedding machine control cabinet 2 can also be equipped with a dedicated electronic unit dedicated to controlling the electric flaps, as described in patent application CN202310062805.8.

[0067] The shedding machine control cabinet 2 can be thermally connected to any not shown mechanical or electronic system of the loom for cooling the coolant passing through the mechanical or electronic system.

[0068] Advantageously, the main fan 222 ventilates the internal space of the chamber 23 of the shedding machine control cabinet 2 and the heat exchanger 222, so that the main fan 222 cools the electronic components by heat dissipation and the coolant flowing through the heat exchanger 21.

[0069] Advantageously, the air extracted from the main fan 222 ensures the cooling of the chamber 23 containing the heat-dissipating electronic components and the cooling of the heat exchanger for cooling the hot water coming from the rotary electric actuators 1111. This maintains the correct operating temperature in the internal space of the chamber 23 to maintain the operability of the shedding machine 1. For example, the shedding machine control cabinet 2 controls the coolant temperature inside the chamber 23 below 60 degrees Celsius and the temperature of the control unit 63 below 90 degrees Celsius.

[0070] Advantageously, the main fan 21 extracts hot air from the shedding machine control cabinet 2 from below and from above, which is the most natural and most effective way of dissipating heat.

[0071] Advantageously, the air is extracted from the front panel 201 located opposite the loom W to minimize the intake of dust and cotton fibers.

[0072] Advantageously, the coolant circulator 2323 is located below the rack units 51, 52, 53 and the coolant is guided along the cabinet joints so that the electronic components are separated from the coolant guiding means, since a coolant leak could damage the electronic unit 64 and jeopardize the operation of the loom W.

[0073] Advantageously, the filters 2014, 2015, 2016 are easy to maintain.

[0074] Advantageously, the rack units 51, 52, 53 are easy to remove.

[0075] Advantageously, the cabinet is lightweight, robust and easy to replace.
