Description

BACKGROUND OF THE INVENTION Area of ​​the invention

[0001] The present invention relates to a motor control device. Related technology

[0002] An industrial machine, such as a machine tool, designed to be driven by a motor, includes a motor control unit mounted on a control console. This unit typically comprises a motor control unit main body, a cooling device for dissipating heat from the motor control unit main body, and a blower motor unit for cooling the cooling device. The blower motor unit frequently stops rotating due to dirt accumulating on it. Each time the blower motor unit stops rotating, it is detached from the motor control unit and replaced. Therefore, there is a need for a more labor-efficient method for replacing the blower motor unit.

[0003] According to a conventional technique for facilitating the replacement of the blower motor unit, the blower motor unit is mounted so that it can be attached / removed from the front side (i.e., from the side from which the control console is operated) (see, for example, Japanese patent JP 4 734 299 B2). Patent specification 1: Japanese patent JP 4 734 299 B2

[0004] DE 10 2018 126 858 A1 describes a motor drive device that can be more easily installed on a mounting element.The motor drive device comprises: a mounting element having a mounting hole; a fan unit designed to be attached to the mounting element, the fan unit having a cover designed to cover the mounting hole; a limiting element designed to limit movement of the cover in a direction away from the mounting element by holding the cover positioned between the limiting element and the mounting element; and a guide mechanism designed to guide an operation of the limiting element as it moves along the cover from a non-limiting position, in which movement of the cover in the away direction is permitted, to a limiting position, in which movement of the cover in the away direction is restricted.

[0005] DE 10 2017 004 959 A1 describes a motor drive device in which a mounting hole for mounting a blower unit is closed by means of a blower fastening element and is provided with a structure that effectively improves operability during maintenance. A latch serving as a regulating element of a motor drive device has a first projecting part, which is designed to be bent downwards after extending horizontally from an upper part thereof, and a second projecting part that projects downwards from a lower part thereof. By arranging the first projecting part in an upper insertion part and arranging the second projecting part in a lower insertion part, a blower unit is secured in a mounting hole of a flange.

[0006] DE 87 14 894 U1 describes a device with a fan insert with at least one axial fan for cooling electrical or electronic assemblies, the dimensions of which in height / width and depth correspond to at least one height, width and depth division step defined in a grid dimension and which are arranged in at least one sub-carrier, the dimensions of which in height, width and depth correspond to at least one height, width and depth division step defined in a grid dimension and which is arranged in a housing, wherein the fan insert is mounted above or below the sub-carrier and extends in height over one height division step.The axial fan is attached to a front panel immediately adjacent to the beginning of the neighboring height division step by means of at least one retaining element, the end of which facing the axial fan is connected to the housing between the top and bottom of the axial fan, and a recess extending approximately across the width of the axial fan is provided in the lower edge of the front panel, the height of which corresponds approximately to the distance between the beginning of the height division step and the bottom of the fan, and through which a filter mat on a large-area recessed flat frame, secured against the axial fan side by a flat grille, can be inserted into the free space under the axial fan. SUMMARY OF THE INVENTION

[0007] Typically, the cooling device is positioned facing the rear of the motor control unit main body, and the blower motor assembly is located above the cooling device. Therefore, when the blower motor assembly is pulled to the front side and removed, it passes over the motor control unit main body. During this process, contaminants such as dirt and / or oil adhering to the blower motor assembly may fall through the upper vents of the motor control unit main body and into the motor control unit main body, contaminating its interior. Therefore, there is a need for a motor control unit in which the blower motor assembly can be easily replaced without contaminating the interior of the motor control unit main body during the replacement process.

[0008] According to one aspect of the present disclosure, a motor control device for mounting on a control console comprises: a motor control device main body; a cooling device arranged to face a rear side of the motor control device main body; a blower motor unit arranged next to the cooling device and removable over an area near the motor control device main body; and a bottom foil element designed to be laid out along a removal path of the blower motor unit when the blower motor unit is removed.

[0009] According to one aspect of the present disclosure, it is possible to provide a motor control device in which a blower motor unit can be easily replaced and the interior of a motor control device main body is not contaminated when the blower motor unit is replaced.

DETAILED DESCRIPTION OF THE INVENTION [First embodiment]

[0010] The following describes one aspect of the present disclosure with reference to the drawings. Fig. Figure 1 is a side view showing a motor control device mounted on a control console according to a first embodiment. Fig. Figure 2 is an enlarged side view of a part of the motor control device according to the first embodiment. As in Fig. As shown in Figure 1, a motor control device 1 is mounted on a control console 100. The control console 100 has a front plate 101, which can be opened, and a rear plate 102, which is arranged parallel to the front plate 101. A motor control device mounting plate 103 for the motor control device 1 is attached along the rear plate 102.

[0011] The motor control device 1 comprises a motor control device main body 11, which is arranged inside the control console 100 and between the front plate 101 and the rear plate 102 such that it projects towards the front plate 101 rather than towards the motor control device mounting plate 103, a cooling device 12, which is arranged such that it faces a rear side of the motor control device main body 11 (i.e. with the motor control device mounting plate 103 arranged between them on a side opposite the motor control device main body 11), and a blower motor unit 13, which is arranged above the cooling device 12.

[0012] The cooling device 12 comprises, for example, several vertically extending cooling fins. For the sake of simplicity, however, the cooling fins of the cooling device 12 are not shown in the drawing. In the drawings, the cooling device 12 is depicted in a rectangular box shape. The cooling device 12 projects outwards from the control console 100 through an opening (not shown) in the rear plate 102 of the control console 100. Therefore, the cooling device 12 and the blower motor unit 13 are arranged outside the control console 100 and covered by a cooling device cover 200, such that they face the rear side of the rear plate 102 (i.e., are arranged on a side facing an outer surface of the control console 100).

[0013] As in Fig. As shown in Figure 2, the blower motor unit 13 comprises a blower motor 131, a mounting plate 132 which holds the blower motor 131, and a front plate 133 which is attached to the mounting plate 132 and is arranged to face the front of the blower motor 131 (i.e., is located on a side closer to the end plate 101). The mounting plate 132 has an air outlet (not shown) through which air is circulated to the cooling device 12 by the rotation of the blower motor 131.

[0014] The motor control device mounting plate 103 has an opening 104 located above the motor control device main body 11. The opening 104 is sized to allow the blower motor 131 and the retaining plate 132 of the blower motor unit 13 to pass through the opening 104, but not the front plate 133. As shown in Fig. As shown in Figure 2, the front plate 133 is in an assembled state in which the blower motor unit 13, held by the retaining plate 132, is positioned above the cooling device 12, such that it completely covers the opening 104 formed in the motor control device mounting plate 103 from inside the control console 100.

[0015] The blower motor unit 13 is designed such that, during replacement, it can be pulled out from its mounted state towards the end plate 101 by removing the front plate 133 of the blower motor unit 13 via an area near the main body 11 of the motor control device. More precisely, the blower motor unit 13 can be pulled out via an area above the main body 11 of the motor control device. In the motor control device 1, an area above a top surface 11a of the main body 11 of the motor control device forms a removal path via which the blower motor unit 13 is removed during replacement. The removal path of the blower motor unit 13 begins at an initial end P1 located closer to the opening 104 and ends at a final end P2 located closer to the end plate 101.In the following description, a direction in which the blower motor unit 13 is removed along the removal path from the starting end P1 to the ending end P2 is defined as "forward".

[0016] A bottom foil element 2 is arranged in the area near the beginning end P1 of the extraction lane. According to the present embodiment, the bottom foil element 2 is made from a web-shaped element wound into a roll and is arranged near the opening 104 on the top surface 11a of the motor control device main body 11. The length and width of the bottom foil element 2 are set such that the bottom foil element 2 can cover the upper ventilation openings (not shown) provided in the top surface 11a of the motor control device main body 11, thus preventing the ingress of contaminants X falling from the blower motor unit 13 during replacement into the blower motor unit 11.

[0017] Any material can be used for the floor foil element 2, provided that the floor foil element 2 made of that material can catch any contaminant that falls from the blower motor 131 and prevent the contaminant from falling into the motor control device main body 11 when the blower motor unit 13 is replaced. More specifically, the floor foil element 2 can, for example, be a sheet made of either metal or resin, rubber, paper, or fabric, or a sheet made of two or more types of composite materials. The floor foil element 2 can be elastic.

[0018] As in Fig. As shown in Figure 2, the bottom foil element 2 has a first end 2a (an end on the side where the starting end P1 of the dispensing lane is located) positioned near the starting end P1 of the dispensing lane. More precisely, the position near the starting end P1 of the dispensing lane is a position between the motor control device mounting plate 103 and one of the several (not shown) upper vents in the top surface 11a of the motor control device main body 11, with one upper vent being closer to the opening 104 than any other upper vent. By having the first end 2a of the bottom foil element 2 positioned near the starting end P1 of the dispensing lane, it is possible to completely cover the upper vents in the top surface 11a of the motor control device main body 11 when the bottom foil element 2 is deployed.The first end 2a of the floor foil element 2 according to the present embodiment has a fastening element 21. The floor foil element 2 is attached to the motor control device mounting plate 103 below the opening 104 by means of the fastening element 21.

[0019] The fastening element 21 can be attached to or removed from the motor control device mounting plate 103 by means of a locking element such as a screw, adhesive, or the like, but this need not be the case. If the fastening element 21 is detachably attached to the motor control device mounting plate 103, the fastening element 21 can, for example, be a connecting element such as a hook that attaches to a fastening element (not shown) provided on the motor control device mounting plate 103, or a magnet that is attracted to the motor control device mounting plate 103. Because the fastening element 21 is detachable, the bottom foil element 2 can be replaced.

[0020] The bottom foil element 2 has a second end 2b (an end on the side where the end P2 of the dispensing track is located) which is provided with a retaining element 22. The retaining element 22 is designed to hold the laid-out state of the bottom foil element 2, which is achieved by laying the rolled-up bottom foil element 2 on the top surface 11a of the motor control device main body 11. Examples of the retaining element 22 include a connecting element such as a hook designed to be attached to a fastening element (not shown) provided at the end P2 of the dispensing track, a magnet and a hook-and-loop fastener designed to be attracted to / attached to a section of the motor control device main body 11 corresponding to the end P2 of the dispensing track, and the like.

[0021] The bottom foil element 2, which is attached to the motor control device mounting plate 103 via the fastening element 21, is designed to be wound into a roll by coiling the bottom foil element 2 from its second end 2b to the fastening element 21. The coiled bottom foil element 2 is positioned at the starting end P1 of the dispensing lane. When an operator uncoils the bottom foil element 2 by pulling forward the second end 2b of the bottom foil element 2, the bottom foil element 2 is therefore deployed over an area from the starting end P1 to the ending end P2 of the dispensing lane. Accordingly, the bottom foil element 2 can completely cover the entire top surface 11a of the motor control device main body 11.

[0022] Next, with reference to the Fig. 3 to 5 the replacement of the blower motor unit 13 of the motor control device 1 configured as described above. Fig. Figure 3 is a side view showing how the floor foil element in roll form is laid out in the motor control device according to the first embodiment. Fig. Figure 4 is a side view showing how the blower motor unit is replaced in the motor control device according to the first embodiment. Fig. Figure 5 is a perspective view showing how the blower motor unit is replaced in the motor control device according to the first embodiment. As shown in Fig. As shown in Figure 3, to replace the blower motor unit 13, the operator first lays out the floor foil element 2, which is wound into a roll and arranged at the beginning end P1 of the dispensing conveyor. More precisely, the operator pulls the second end 2b of the floor foil element 2 forward so that the floor foil element 2 is unrolled.

[0023] Once the bottom foil element 2 is fully deployed, the operator hooks the retaining element 22 onto the motor control device main body 11, for example, so that the retaining element 22 is secured. This allows the deployed state of the bottom foil element 2 to be maintained, thus preserving the state in which the bottom foil element 2 covers the entire top surface 11a of the motor control device main body 11.

[0024] The operator then pulls the front plate 133 of the blower motor unit 13 forward. Accordingly, the blower motor unit 13 is positioned as shown in Fig. 4 and Fig. Figure 5 shows the material being extracted along the extraction path through opening 104 forward to the end P2. During this process, a contaminant X adhering to the blower motor 131 may fall downwards, as shown in Figure 5. Fig. Figure 4 shows that the contaminant X, which falls down in this way, is intercepted by the bottom foil element 2 laid along the extraction path of the blower motor unit 13. Therefore, the contaminant X does not penetrate the motor control device main body 11.

[0025] Thus, the interior of the motor control device main body 11 is not contaminated when the blower motor unit 13 is replaced in the motor control device 1 configured as described above. Furthermore, since the blower motor unit 13 can be removed simply by pulling it forward through the opening 104, replacing the blower motor unit 13 is easy. After installing a new blower motor unit through the opening 104, the floor foil element 2 is rewound into a roll.

[0026] In the present embodiment, the floor membrane element 2 is produced in roll form by rolling it up from its first side next to the retaining element 22, which is provided at the second end 2b, to the fastening element 21. Alternatively, although not shown in the drawings, the floor membrane element 2 can be produced in roll form by rolling it up from its second side next to the fastening element 21 to the retaining element 22. In this configuration, it is possible to deploy the floor membrane element 2 simply by pulling the retaining element 22 forward. In this case, the second side of the floor membrane element 2 next to the fastening element 21 can be pre-tensioned in the direction of rolling by an elastic element such as a spring. This allows the deployed floor membrane element 2 to be easily returned to its original roll form. [Second embodiment]

[0027] Fig. Figure 6 is an enlarged side view of part of a motor control device according to a second embodiment. Fig. Figure 7 is an enlarged side view of a roll-shaped floor foil element in the motor control device according to the second embodiment. The elements of a motor control device 1A according to the second embodiment that correspond to the elements of the motor control device 1 according to the first embodiment are assigned the same reference numerals. These elements of the second embodiment have the same configurations as those of the first embodiment and are therefore not described below. Reference may be made to the preceding descriptions of the corresponding elements for these elements of the second embodiment. The motor control device 1A according to the second embodiment differs from the motor control device 1 according to the first embodiment in that a second end 2b of a floor foil element 2 is detachably attached to a blower motor unit 13.

[0028] In the second embodiment, the bottom film element 2 also has a first end 2a, which is located near the beginning end P1 of a dispensing lane. More precisely, the first end 2a of the bottom film element 2 is attached to a winding shaft 23, which is located near the beginning end P1 of the dispensing lane. The two opposite ends of the winding shaft 23 are rotatably held by paired shaft retaining plates 24, 24 such that the winding shaft 23 is positioned between the shaft retaining plates 24, 24. The shaft retaining plates 24, 24 are mounted on the motor control device mounting plate 103 such that the shaft retaining plates 24, 24 project forward from it. The winding shaft 23 can be detachably attached to the shaft retaining plates 24, 24.

[0029] The second end 2b of the floor foil element 2 according to the present embodiment has a fastening element 25. The second end 2b of the floor foil element 2 is detachably attached to the front plate 133 of the blower motor unit 13 by means of the fastening element 25. Examples of the fastening element 25 include a connecting element such as a hook designed to be attached to a fastening element (not shown) provided on the front plate 133, a magnet and a hook-and-loop fastener designed to be attracted to / attached to the front plate 133, and the like.

[0030] Next, the following will refer to Fig. 8 and Fig. 9 the replacement of the blower motor unit 13 in the motor control device 1A configured as above is described. Fig. Figure 8 is a side view showing how the blower motor unit is replaced in the motor control device according to the second embodiment. Fig. Figure 9 is a side view showing how the blower motor unit is replaced in the motor control device according to the second embodiment. According to the present embodiment, when replacing the blower motor unit 13, an operator pulls the front plate 133 of the blower motor unit 13 forward, as shown in Fig. 8 shown.

[0031] The second end 2b of the floor foil element 2 is attached to the front plate 133 of the blower motor unit 13 by means of the fastening element 25. Therefore, the floor foil element 2 is unwound by rotating the winding shaft 23 when the blower motor unit 13 is pulled forward. Accordingly, the second end 2b of the floor foil element 2 is pulled out together with the blower motor unit 13. This causes the floor foil element 2 to be extended as shown in Fig. 9 shown, in conjunction with the movement with which the blower motor unit 13 is removed, gradually laid out along the removal path.

[0032] During the process of removing the blower motor unit 13 (i.e., during the process of laying out the floor foil element 2), a contaminant X adhering to the blower motor 131 may possibly fall downwards, as shown in Fig. 9 shown. However, the contaminant X falling in this way is captured by the bottom foil element 2, which is designed to be used in conjunction with the movement with which the blower motor unit 13 is removed. Therefore, the contaminant X does not penetrate the interior of the motor control device main body 11.

[0033] Therefore, the motor control device 1A also achieves results similar to those achieved by the motor control device 1 according to the first embodiment. Furthermore, since the floor foil element 2 is deployed in conjunction with the movement used to remove the blower motor unit 13, it is not necessary to deploy the floor foil element 2 before replacing the blower motor unit 13, thus eliminating the possibility of the operator forgetting to deploy the floor foil element 2.

[0034] Once the operator has finished pulling out the blower motor unit 13, the operator releases the fastening element 25 from the blower motor unit 13 and removes the blower motor unit 13. The base film element 2 is then re-wound around the winding shaft 23 so that it is wound into a roll. Although not shown, the winding shaft 23 can be pre-tensioned in the winding direction by means of an elastic element such as a spring. This configuration allows the base film element 2 to be easily wound around the winding shaft 23 after it has been released from the blower motor unit 13. [Third embodiment]

[0035] Fig. Figure 10 is a perspective view of a motor control device according to a third embodiment. Fig. Figure 11 is an enlarged side view of a portion of the motor control device according to the third embodiment. The same reference numerals are assigned to the elements of a motor control device 1B according to the third embodiment that correspond to the elements of the motor control device 1 according to the first embodiment. These elements of the third embodiment have configurations that are identical to those of the first embodiment and are therefore not described below. Reference may be made to the preceding descriptions of the corresponding elements for these elements of the third embodiment.In the motor control device 1B according to the third embodiment, a motor control device main body 11 comprises wall plate elements 111, 111 provided in pairs, which are arranged on two opposite sides of a removal lane of a blower motor unit 13 such that they enclose the removal lane from two opposite sides.

[0036] As in Fig. As shown in Figure 10, the wall plate elements 111, 111 are elements that extend upwards from two side surfaces 11b, 11b of the motor control device main body 11 such that they are higher than a top surface 11a, the two side surfaces 11b, 11b extending along a removal direction of the blower motor unit 13. A motor control device mounting plate 103 has an opening 104 at a position between the wall plate elements 111, 111.

[0037] The inner surfaces 111a, 111a of the paired wall panel elements 111, 111 are each provided with rail elements 112, 112. The paired rail elements 112, 112 have an identical structure. The paired rail elements 112, 112, each of which has a plate-like shape, project from the inner surfaces 111a, 111a of the wall panel elements 111, 111 such that they come into contact with the undersides of two opposite end sections of the blower motor unit 13 when the blower motor unit 13 is removed forward through the opening 104.

[0038] As in Fig. As shown in Figure 11, the first ends 112a, 112a (ends on a side where a starting end P1 of the extraction track is located) of the rail elements 112, 112 are arranged near the motor control device mounting plate 103. The rail elements 112, 112 are designed such that, with increasing distance from their first ends 112a, 112a and increasing proximity to their second ends 112b, 112b (the ends on a side where a closing end P2 of the extraction track is located), they gradually move upwards away from the top surface 11a of the motor control device main body 11.

[0039] The rail elements 112, 112 form the removal path for the blower motor unit 13. Thus, the blower motor unit 13, which is removed forward through the opening 104, is guided along the rail elements 112, 112 and gradually lifted upwards away from the top 11a of the motor control device main body 11. This facilitates the removal of the blower motor unit 13, thereby significantly simplifying its replacement.

[0040] In the motor control device 1B, a bottom foil element 2 with a structure identical to that of the first embodiment is arranged at a position near the beginning end P1 of the extraction lane. Several upper ventilation openings 113 are provided on the top surface 11a of the motor control device main body 11, which is located near the motor control device mounting plate 103.

[0041] Next, the following will refer to Fig. 12 the replacement of the blower motor unit 13 of the motor control device 1B configured as described above. Fig. Figure 12 is a side view showing how the blower motor unit is replaced on the motor control device according to the third embodiment. To replace the blower motor unit 13, the operator first lays out the floor foil element 2 along the paired rail elements 112.

[0042] When the base foil element 2 is fully deployed, it covers the top 11a of the motor control device main body 11 along the rail elements 112, 112. A retaining element 22 of the base foil element 2, for holding the deployed state of the base foil element 2, is attached to the second ends 112b, 112b of the rail elements 112, 112.

[0043] The operator then pulls the front plate 133 of the blower motor unit 13 forward so that the blower motor unit 13 is gradually pulled upwards through the opening 104 along the removal path formed by the rail elements 112, 113. In this case as well, a droplet falling from the blower motor 131 (in Fig. 12 (not shown) Contamination X is captured by the bottom foil element 2 and therefore does not enter the interior of the motor control device main body 11.

[0044] Thus, even with the motor control device main body 1B configured as described above, the interior of the motor control device main body 11 is not contaminated when the blower motor unit 13 is replaced. Furthermore, the blower motor unit 13 can only be guided through the paired rail elements 112, 113 and removed upwards by simply pulling it forward through the opening 104. Therefore, replacing the blower motor unit 13 in the motor control device 1B is easier than in the first embodiment.

[0045] In the motor control device 1B, the bottom film element 2 in roll form can be the bottom film element 2 wound around the winding shaft 23 shown in connection with the second embodiment. [Other embodiments of the floor foil element]

[0046] Fig. Figure 13 is a side view of a floor foil element according to a further embodiment. Fig. Figure 13 shows neither an opening 104 nor a blower motor unit 13. One in Fig. The floor foil element 2A shown in Figure 13 has a folded shape. The floor foil element 2A is folded such that it is stacked upwards near a motor control device mounting plate 103 on a top surface 11a of a motor control device main body 11.

[0047] The floor foil element 2A is attached to the motor control device mounting plate 103 by means of a fastening element 21 provided at a first end 2a. Thus, an operator can, in order to lay out the floor foil element 2A, pull out a second end 2b of the floor foil element 2A in a similar manner to the floor foil element 2 shown in connection with the first embodiment. Similarly to the second embodiment, the second end 2b of the floor foil element 2A can be detachably attached to the blower motor unit 13 by means of a fastening element 25.

[0048] Fig. Figure 14 is a side view of a floor foil element according to yet another embodiment. Fig. Neither an opening 104 nor a blower motor unit 13 is shown in section 14. A Fig.The floor foil element 2B shown in Figure 14 has a bellows shape. The floor foil element 2B is folded such that it is stacked forward near a motor control device mounting plate 103 on a top surface 11a of a motor control device main body 11.

[0049] The floor foil element 2B is attached to the motor control device mounting plate 103 by means of a fastening element 21 provided at a first end 2a. Thus, an operator can extend the floor foil element 2B to lay it out in a similar manner to the floor foil element 2 shown in connection with the first embodiment by pulling out a second end 2b of the floor foil element 2B. Similarly to the second embodiment, the second end 2b of the floor foil element 2B can be detachably attached to the blower motor unit 13 by means of a fastening element 25.

[0050] The fastening element 21 provided at the first end 2a of the base foil element 2, 2A, 2B can be attached to the top 11a of the motor control device main body 11.

[0051] In the embodiment described above, the blower motor unit 13 is arranged above the cooling device 12. Alternatively, the blower motor unit 13 can be arranged in any position, as long as it is located next to the cooling device 12.
