Detailed Description

Hereinafter, a control device according to the present invention will be described in detail with reference to the drawings, taking preferred embodiments as examples.

Detailed description of the preferred embodiments

Fig. 1 is an overall configuration diagram of a control device 10 according to an embodiment. The directions described below are based on arrows shown in the drawings. The front direction and the rear direction are opposite directions to each other, the left direction and the right direction are opposite directions to each other, and the up direction and the down direction are opposite directions to each other. In addition, the downward direction is also the direction of gravity.

The control device 10 of the present embodiment is, for example, a control device that controls an industrial robot. An industrial robot is, for example, a machine that is disposed in a factory, performs a work for producing an industrial product in place of or in cooperation with a human. The control device 10 includes a plurality of electrical components for controlling the industrial robot. The control device 10 may be a control device for controlling a machine or a device other than the industrial robot.

The control device 10 includes a main body 12, a plurality of (2) mounting members 14, a plurality of (4) casters 16, a support member 17, and a projecting member 20. The main body 12 includes the plurality of electrical components and a housing for housing the plurality of electrical components, and is responsible for controlling the industrial robot. The body 12 is substantially cuboid in shape, having an upper face 12a and a bottom face 12 b. In the front-back and left-right direction, the left-right direction of the main body 12 of the present embodiment is a long side, and the front-back direction is a short side.

In the present embodiment, the mounting member 14 is attached to each of both sides in the left-right direction (1 st direction) in the bottom surface 12 b. As described later, the mounting member 14 is a member for providing the caster 16 on the control device 10 via itself. The mounting member 14 has: a 1 st member 22 extending in the front-rear-left-right direction and attached to the bottom surface 12b side of the main body 12; a 2 nd member 24 extending downward from the 1 st member 22; and a 3 rd member 26 having a plate shape and extending in the front-rear right-left direction from the 2 nd member 24. That is, the mounting member 14 has a substantially horizontal n-shaped cross section.

In the above description, the 1 st member 22 and the 3 rd member 26 of the left-side mounting member 14 of the control device 10 extend in the left direction from the 2 nd member 24. The 1 st member 22 and the 3 rd member 26 of the right-side mounting member 14 of the control device 10 extend in the right direction from the 2 nd member 24. The 2 3 rd members 26 are formed with through holes 28, which will be described later.

The caster 16 is provided on the bottom surface 12b side via the 3 rd member 26. The 4 casters 16 of the present embodiment are attached to 2 mounting members 14 on the lower side of the 3 rd member 26, respectively. The 2 casters 16 attached to the 1 attachment member 14 are spaced apart from each other by a predetermined interval in the front-rear direction (2 nd direction). By providing the caster 16, it is easier for the operator to move the control device 10 in a plane.

In the configuration of fig. 1, a space is left between the 1 st member 22 and the 3 rd member 26. In this space, the fork of the forklift can be inserted. By supporting the bottom surface 12b with the fork, the control device 10 can be easily lifted.

The support member 17 is a general term for a member provided on the upper surface 12a to support the control device 10' (described later) stacked thereon. The support member 17 has a substantially rectangular parallelepiped support portion 18 extending in the upward direction. The number of the support portions 18 that the support member 17 can have is not particularly limited, but is 2 in the present embodiment. Although the arrangement of the 2 support portions 18 is not particularly limited, in the present embodiment, one is provided on the left direction side of the upper surface 12a, and the other is provided on the right direction side of the upper surface 12 a.

The support portion 18 has a height (length in the vertical direction) equal to or greater than the length from the 3 rd member 26 to the installation surface of the caster 16. In the front-rear-left-right direction, the support portion 18 has a long front-rear direction and a short left-right direction. The length of the support portion 18 in the longitudinal direction is equal to or less than the interval between 2 casters 16 attached to 1 attachment member 14.

The support portion 18 has a support surface 18a facing in an upward direction. The support surface 18a has a hole 30 formed therein. The hole 30 will be described later. In the present embodiment, the number of the support portions 18 is 2. The 2 support portions 18 are respectively provided on both sides in the left-right direction in the upper surface 12 a.

The projecting member 20 projects downward from the bottom surface 12 b. The projecting member 20 projects downward in such a length as not to obstruct the movement of the control device 10 (not to contact the floor) by the caster 16. The protruding member 20 has, for example, a substantially box shape, and may have electric components on the inside thereof in the same manner as the main body 12. The projecting member 20 is substantially box-shaped and the electric component is provided inside the projecting member (see, for example, modification 1 described later).

Hereinafter, a state in which 2 control devices 10 are stacked will be described. In addition, the number of stacked control devices 10 is not limited to 2. In the following, a symbol ""' "indicating one of the stacked 2 control devices 10 and its constituent elements may be distinguished.

Fig. 2 is a diagram showing a state in which 2 control devices 10 are stacked. Fig. 3A is a rear view (a viewpoint viewed from the rear direction) of fig. 2. Fig. 3B is a side view (a viewpoint viewed from the right direction) of fig. 2.

Fig. 2, 3A, and 3B show a state in which the control device 10' is stacked on the control device 10. In this state, the support portion 18 of the lower control device 10 supports the control device 10'. More specifically, the 2 support portions 18 provided on both sides in the left-right direction of the lower control device 10 support the 3 rd member 26 'on the upper side by the support surfaces 18a, whereby the control device 10' is supported.

At this time, the support portion 18 of one (left side) of the 2 support portions 18 is sandwiched in the front-rear direction by the 2 casters 16 'provided on the left side of the control device 10'. The other (right) support portion 18 is sandwiched in the front-rear direction by the 2 casters 16 'provided on the right side of the control device 10'.

The 2 casters 16' preferably hold the support 18 in contact with the support 18. However, "sandwiching" in the present embodiment is not necessarily the object on the sandwiched side (the support portion 18) and the object on the sandwiching side (the caster 16') that are in contact with each other.

By sandwiching 1 support portion 18 in the front-rear direction by 2 casters 16 'on both sides in the left-right direction, the movement of the control device 10' in the front-rear direction is restricted. That is, the control device 10' is prevented from shifting in the front-rear direction on the control device 10. In the case where the 2 casters 16 'sandwich the support portion 18, the control device 10' is more prevented from being displaced in the front-rear direction.

In the state where the control device 10 'is disposed on the control device 10, the protruding member 20' is located between the 2 support portions 18, and is more preferably sandwiched between the 2 support portions 18. Thereby, the movement of the control device 10 'in the left-right direction is restricted, and thus the control device 10' is prevented from being shifted in the left-right direction on the control device 10. In the case where the 2 support portions 18 sandwich the protruding member 20 ', the control device 10' is more prevented from being shifted in the left-right direction.

As described above, in the present embodiment, when the control device 10 'is stacked on the control device 10, the control device 10' is prevented from being displaced in the front-rear right-left direction. Therefore, the plurality of control devices 10 (control devices 10') are easily stabilized in the stacked state.

The shape of the upper surface 12a of the control device 10 is not limited to a rectangular shape, unlike a base plate of a carriage. Therefore, when the control device 10 ' is stacked on the control device 10, the region capable of supporting the caster 16 ' of the control device 10 ' does not necessarily exist on the upper surface 12a side. In this embodiment, the support portion 18 of the lower controller 10 supports a portion of the upper controller 10 'other than the caster 16'. Therefore, there is no problem even if there is no area on the upper surface 12a side of the control device 10 where the caster 16 'of the control device 10' can be supported from below.

Fig. 4A is a partially enlarged view of the process of stacking 2 control devices 10. Fig. 4B is a partially enlarged view of a state in which 2 control devices 10 are stacked.

Here, the through hole 28 (through hole 28 ') of the 3 rd member 26 (3 rd member 26') and the hole 30 of the support portion 18 will be described in detail. When the 3 rd member 26 'is supported by the support surface 18a, the through hole 28' and the hole 30 communicate with each other. A fastening member 32 can be inserted into the through hole 28' and the hole 30 which are communicated with each other.

The fastening member 32, which is, for example, a bolt or a screw, fastens the 3 rd member 26' and the support member 17 to each other. In connection with this, it is preferable that a screw (female screw) to which a screw (male screw) formed in a bolt or a screw is screwed is formed on the inner surfaces of the through hole 28' and the hole 30.

By fastening the 3 rd member 26 'and the support member 17 to each other, the control device 10' and the control device 10 are fastened to each other. In this state, by lifting one of the control device 10 and the control device 10', the other can be lifted as well. This makes it easier to move the plurality of control devices 10 (control devices 10') stacked together.

The number of the through holes 28 'and the number of the holes 30 are 4 in the present embodiment, but the number of the through holes 28' and the number of the holes 30 are not limited to this.

As described above, according to the present embodiment, the control device 10 which is easily stabilized when stacked can be provided.

Modification example

Although the embodiments of the present invention have been described above as examples of the present invention, it is needless to say that various changes and improvements can be made to the above embodiments. Embodiments to which such changes and improvements are made are also within the technical scope of the present invention, as apparent from the scope of the claims.

Modification example 1

Fig. 5 is a rear view (a perspective view from the rear) of a state in which 2 control devices 10 according to modification 1 are stacked. Fig. 5 shows a state in which the control device 10 is stacked on the control device 10'.

As shown in fig. 5, the projecting member 20 may have 2 columnar or plate members projecting downward from both sides in the left-right direction of the bottom surface 12 b. This prevents the control device 10 stacked above from shifting in the left-right direction, as in the embodiment. As shown in fig. 5, when the control device 10 is stacked on the control device 10 ', the projecting member 20 is located on the right side with respect to the left support portion 18 ' and on the left side with respect to the right support portion 18 '. The protruding member 20 and the support portion 18' are preferably in contact with each other from the viewpoint of preventing the deviation of the control device 10, although this is not an essential matter.

Modification 2

The support portion 18 may be detachably provided from the control device 10. For example, when a plurality of control devices 10 are stacked, the uppermost control device 10 is not supported by the support portion 18 provided in the uppermost control device. In this case, and when it is determined that the stacking is not necessary thereafter, the support portion 18 of the uppermost control device 10 can be removed according to the present modification.
