  By the way, when the clearance gap between the inner surface of a recessed part and a wire is large, when winding a tape around a wire, the position of a wire is difficult to stabilize. In this case, the winding accuracy tends to vary, for example, wrinkles occur on the tape after winding, and the actual winding position deviates from a desired position. Therefore, in order to wind the tape around the wire with high accuracy, it is necessary to use a plurality of tape winding devices in accordance with the diameter of the wire.

  Then, an object of this invention is to provide the tape winding apparatus which can wind a tape around a wire with high precision.

  In order to solve the above-described problem, the tape winding device according to the first aspect is a tape winding device that winds a tape around a wire, and a rotation in which a concave portion that is recessed toward the center is formed in a part of the outer periphery. A body, a housing member having a groove capable of housing the wire, a rotation driving unit that rotates the rotating body, and one of the main surfaces on both sides is an adhesive surface and the other is A tape supply unit that supplies a tape that is a non-adhesive surface toward the recess.

  The tape winding apparatus according to the second aspect is the tape winding apparatus according to the first aspect, wherein the housing member is an elastic member.

  The tape winding apparatus according to a third aspect is the tape winding apparatus according to the second aspect, wherein the housing member is a sponge.

  A tape winding apparatus according to a fourth aspect is the tape winding apparatus according to any one of the first to third aspects, wherein the groove has a taper in which the groove width decreases along the depth direction. Part.

  A tape winding apparatus according to a fifth aspect is the tape winding apparatus according to any one of the first to fourth aspects, wherein the housing member is detachable from the recess.

  The tape winding apparatus according to a sixth aspect is the tape winding apparatus according to any one of the first to fifth aspects, further comprising a sheet member provided along the groove, and the sheet The member is more slippery than the housing member with respect to the tape.

  According to the 1st-6th aspect, the accommodating member which has a groove | channel which can accommodate a wire is provided inside the recessed part of a rotary body. The gap between the inner surface of the groove and the wire is smaller than the gap between the inner surface of the recess and the wire. Therefore, in the said aspect, compared with the aspect which accommodates a wire in a recessed part, without providing an accommodating member, the position of a wire is easy to be stabilized at the time of tape winding operation | work. As a result, the tape can be wound around the wire with high accuracy.

  According to the second aspect, the housing member is an elastic member. Even when the diameter size of the wire is larger than the groove width of the housing member, the wire is housed in the housing member in a close contact state by the restoring force of the housing member elastically contracted in the thickness direction. Therefore, the tape can be wound with high accuracy on a plurality of types of wires having different diameter sizes.

  According to the third aspect, the housing member is a sponge. Since the sponge is porous, it is easily elastically contracted, and the restoring force in the elastically contracted state is small. Therefore, even if it is several types of wire from which diameter size differs, it is easy to accommodate in the contact | adherence state inside the accommodating member.

  According to the fourth aspect, the groove includes a tapered portion in which the groove width decreases along the depth direction. Since the wire having a small diameter size is housed inside the housing member at a deep position in the groove, the position of the wire is likely to be stable during the tape winding operation. As a result, the tape can be wound around the wire with high accuracy.

  According to the 5th aspect, the accommodating member is detachable with respect to a recessed part. Therefore, by selecting one housing member from a plurality of housing members having different shapes and materials and attaching the housing member to the recess, the tape can be wound with high accuracy on a plurality of types of wires having different diameter sizes.

  According to the sixth aspect, the sheet member is provided along the groove of the housing member. Further, the sheet member is easier to slide than the housing member with respect to the tape. Therefore, the housing member is not easily worn during the tape winding operation.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the component described in this embodiment is an illustration to the last, and is not a thing of the meaning which limits the scope of the present invention only to them. In the drawings, the size and number of each part may be exaggerated or simplified as necessary for easy understanding.

<1. First Embodiment>
Hereinafter, the tape winding apparatus 100 according to the first embodiment will be described. FIG. 1 is a schematic configuration diagram illustrating a tape winding apparatus 100 according to the first embodiment.

  The tape winding device 100 is a device that winds the tape 90 around the outer periphery of the wire 80. Hereinafter, the tape winding apparatus 100 that winds the tape 90 after cutting to a predetermined length around the outer periphery of the wire 80 will be described. The tape winding apparatus winds the tape 90 after winding the tape 90 around the outer periphery of the wire 80. You may cut | disconnect. The tape winding apparatus 100 includes a tape supply unit 10, a rotating body 20, a housing member 70, a rotation driving unit 30, and a cutting unit 40.

  As the wire 80, a plurality of electric wires may be assumed, but other wire members may be used. In FIG. 1 and the subsequent drawings, one wire bundle is drawn as the wire rod 80 for the purpose of simplifying the illustration. The tape 90 is an adhesive tape in which one main surface is an adhesive surface 92 having adhesiveness, and the other main surface is a non-adhesive surface 94 having no adhesiveness.

  The tape supply unit 10 includes a tape winding body support unit 12 and a relay unit 14. The tape winding body support part 12 is a rod-shaped member provided along an axis extending in parallel with the rotation center axis Q1 of the rotary body 20. The tape winding body support portion 12 is inserted through a hollow portion at the center of the tape winding body 900 formed by winding the belt-like tape 90. By pulling out the tip end portion of the tape 90 from the tape winding body 900, the tape winding body support portion 12 is rotated around the axis.

  The relay unit 14 is a rotatable roller and supports an intermediate portion of the tape 90 drawn from the tape winding body 900 to the vicinity of the rotating body 20. The relay unit 14 abuts on a non-adhesive surface 94 opposite to the adhesive surface 92 of the tape 90. Further, the relay unit 14 has a function of changing the supply direction of the tape 90.

  In this way, the tape supply unit 10 supplies the tip end portion of the tape 90 extending from the tape winding body 900 to the outside of the opening 26 of the recess 24. It is not essential that the tape supply unit 10 includes the relay unit 14, and the relay unit 14 may not be provided. Further, a tape feeding mechanism for pulling out the tape 90 from the tape winding body 900 may be provided in the vicinity of the tape winding body 900.

  The rotating body 20 is a thick plate-like member in which a concave portion 24 that is recessed in a U shape in a side view is formed toward a center at a part of the outer periphery thereof. The rotating body 20 has a shape in which the concave portion 24 is cut out in a U shape from a part of the outer peripheral surface of the disk-shaped member toward the center. The rotating body 20 is rotated around the rotation center axis Q1 extending in the width direction of the rotating body 20 (perpendicular to the paper surface in FIG. 1) by the rotation driving unit 30.

  The housing member 70 is an elastic member (for example, a sponge) provided inside the recess 24. The outer surface 72 of the housing member 70 is U-shaped in a side view like the inner surface 25 of the recess 24, and the housing member 70 is provided inside the recess 24 by bonding these surfaces to each other. The inner surface 71 of the housing member 70 is V-shaped in a side view, and a portion surrounded by the inner surface 71 functions as a groove 73 that can accommodate the wire 80. As shown in FIG. 1, in the present embodiment, the entire groove 73 has a tapered shape in which the groove width decreases along the depth direction. More specifically, in the side view, the inner surface 71 has a semicircular arc shape at the innermost portion in the depth direction of the groove 73, and the inner surfaces 71 on both sides in the width direction extend from the opening 26 side to the portion. Approaching a straight line.

  As shown in FIG. 1, the rotation center axis Q <b> 1 passes through the groove 73. Therefore, the rotating body 20 can be rotated around the wire 80 by disposing the wire 80 in the groove 73 so as to overlap the rotation center axis Q1.

  The rotation drive unit 30 is a drive unit that rotates the rotating body 20, and includes a plurality of (for example, three) roller members 32 and a power source 34 such as a motor that rotates at least one of the roller members 32. . The plurality of roller members 32 are provided in contact with the outer peripheral surface of the rotating body 20, and the rotating body 20 is rotatably supported by the plurality of roller members 32. When the at least one roller member 32 is rotated by the power source 34, the rotating body 20 supported by the plurality of roller members 32 is passively rotated. The plurality of roller members 32 may be directly rotated by the power source 34 or indirectly rotated by the power source 34 via a relay transmission mechanism such as a gear. Also good.

  The rotation center axis of each roller member 32 is parallel to the rotation center axis Q1 of the rotating body 20. The rotating body 20 and each roller member 32 are formed in a gear shape, for example, and the teeth formed on the outer peripheral portions thereof mesh with each other, so that the meshing members rotate opposite to each other. In the present embodiment, the case where the rotating body 20 is rotatable in both directions around the rotation center axis Q1 will be described. However, the rotating body 20 may be configured to be rotatable in at least one direction.

  The cutting unit 40 includes a cutting blade 42 facing the rotating body 20 and a drive source (not shown) that moves the cutting blade 42 in a direction toward or away from the rotating body 20. The cutting blade 42 extends in a direction along the rotation center axis Q 1, and the width of the cutting blade 42 is larger than the width of the tape 90 in this direction. For this reason, when the cutting blade 42 is brought close to the rotating body 20 by the drive source, the tape 90 positioned on the outer peripheral portion of the rotating body 20 is cut by the cutting blade 42. After the tape 90 is cut, the cutting blade 42 is moved away from the rotating body 20 by the drive source.

  The drive of each drive unit in the tape winding apparatus 100 is controlled by the control unit 50.

  Next, the operation of the tape winding apparatus 100 will be described with reference to FIGS. 2-5 is a figure which shows a mode that the tape 90 is wound around the wire 80 with the tape winding apparatus 100. FIG. For the purpose of preventing the illustration from becoming complicated, the configurations relating to the tape supply unit 10, the rotation drive unit 30, and the control unit 50 are omitted in FIGS.

  In the initial state, the tape 90 supplied from the tape supply unit 10 is located outside the opening 26 of the recess 24. A holding device (not shown) holds both sides of the portion of the wire 80 around which the tape 90 is wound. And the rotation drive part 30 rotates the rotary body 20 so that the opening 26 of the recessed part 24 may face the said part of the wire 80 hold | maintained at the holding | maintenance apparatus. As a result, as shown in FIG. 2, the tape 90 is arranged between the wire 80 and the opening 26 of the recess 24.

  Next, the wire 80 is moved into the recess 24 toward the rotation center axis Q1 of the rotating body 20 by driving the holding device. At this time, since the adhesive surface 92 of the tape 90 faces the wire 80 side, a part of the outer periphery of the wire 80 is attached to the adhesive surface 92 of the tape 90 by bringing the wire 80 closer to the tape 90. As the wire 80 is moved into the recess 24 with the adhesive surface 92 of the tape 90 attached to the wire 80, a new tape 90 is pulled out from the tape winding body 900. Instead of moving the wire 80 into the recess 24 as in the present embodiment, the tape winding device 100 is moved toward the wire 80 so that the wire 80 is disposed in the recess 24. May be.

  Since the accommodating member 70 is provided inside the recess 24, the wire 80 with the tape 90 attached thereto is accommodated in the groove 73 of the accommodating member 70 as shown in FIG. The gap between the inner surface 71 of the groove 73 and the wire rod 80 is smaller than the gap between the inner surface 25 of the recess 24 and the wire rod 80. Therefore, in the present embodiment, the position of the wire 80 is easily stabilized as compared with an aspect in which the wire 80 is accommodated in the recess 24 without providing the accommodation member 70. Generally, when the position of the wire 80 is not stable, the wire 80 swings during the tape winding operation, wrinkles occur in the tape 90 after winding, the actual winding position deviates from a desired position, etc. Variations are likely to occur. On the other hand, in this embodiment, since the position of the wire 80 is stabilized by the housing member 70, the tape 90 can be wound around the wire 80 with high accuracy.

  In the present embodiment, the housing member 70 is an elastic member. Therefore, when the wire 80 is moved toward the rotation center axis Q1, the wire 80 is smoothly moved until the wire 80 and the groove 73 are in contact with each other, and after the wire 80 and the groove 73 are in contact with each other, The wire 80 is moved toward the rotation center axis Q1 while expanding the accommodating member 70 by elastic deformation.

  For this reason, even when the diameter of the wire 80 is larger than the groove width of the groove 73, the wire 80 is accommodated inside the accommodation member 70 by the restoring force of the accommodation member 70 elastically contracted in the thickness direction. (See FIG. 3). When the diameter size of the wire 80 is small, the amount of elastic deformation of the housing member 70 is also small. When the diameter size of the wire 80 is large, the amount of elastic deformation of the housing member 70 is also large. The tape 90 can be wound with high accuracy on a plurality of types of wires having different sizes. Here, the diameter size of the wire rod 80 is the diameter size of the wire rod when the wire rod 80 is composed of one wire rod, and the diameter size of the wire rod 80 when the wire rod 80 is composed of a plurality of wire rods. This is the size of the virtual outer diameter of the aggregate. The diameter size of the wire 80 is, for example, 10 mm in diameter.

  In a state where the wire rod 80 with the tape 90 attached is inserted into the groove 73, the rotation center axis Q1 of the rotating body 20 and the center axis Q2 of the wire rod 80 extending in parallel with the rotation center axis Q1 coincide. It is desirable. In the present embodiment, the accommodating member 70 has the same shape on both sides in the groove width direction, and the rotation center axis Q1 is located at the center in the groove width direction. Therefore, by accommodating the wire 80 in the groove 73, the accommodating member 70 is similarly elastically deformed on both sides in the groove width direction, and the central axis Q2 of the wire 80 is also located at the center in the groove width direction. Further, in the depth direction of the groove 73, the driving amount of the holding device that holds the wire 80 is controlled so that the center axis Q2 and the rotation center axis Q1 coincide. Thereby, even if the rotating body 20 is rotated, the holding device can stably hold the wire 80 in the same position, and the tape 90 can be wound around the wire 80 with high accuracy. Here, the central axis Q2 of the wire 80 is the central axis of the wire when the wire 80 is composed of one wire, and the plurality of wires when the wire 80 is composed of a plurality of wires. Is an imaginary central axis (for example, an axis serving as the center of gravity of each central axis of a plurality of wire rods).

  When the rotation drive unit 30 rotates the rotating body 20 counterclockwise in the drawing, the tape 90 is wound around the outer peripheral portion of the wire 80 held by the holding device. At this time, as the tape 90 is pulled by the rotation of the rotating body 20, the tape winding body 900 rotates and the tape 90 is newly drawn, and the relay unit 14 passively rotates. Thereby, the tape 90 can be fed satisfactorily without hindering the winding of the tape 90 by the rotating body 20. When the rotating body 20 is rotated by a predetermined amount by the rotation driving unit 30, the rotation driving unit 30 stops driving, and the rotation of the rotating body 20 is also stopped accordingly.

  Subsequently, as shown in FIG. 4, the drive source of the cutting unit 40 brings the cutting blade 42 closer to the portion of the tape 90 located on the outer periphery of the rotating body 20. As a result, as shown in FIG. 5, the tape 90 is cut, and the cutting blade 42 is moved to the original position by the drive source of the cutting unit 40.

  Thereafter, the rotation drive unit 30 rotates the rotating body 20 counterclockwise in the drawing, so that the unwrapped portion on the wire 80 side of the cut tape 90 is placed on the outer periphery of the wire 80 held by the holding device. Wound up. Thereby, a series of tape winding work is completed.

  After the tape winding operation is completed, the rotating body 20 is rotated by the rotation driving unit 30 so that the concave portion 24 of the rotating body 20 is at the initial position (the position shown in FIG. 2) of the tape winding operation. Is wound out of the recess 24.

  Next, a case where the tape 90 is wound around the wire 81 having a diameter smaller than that of the wire 80 will be described with reference to FIG. FIG. 6 is a diagram illustrating a state in which the tape 90 is wound around the wire 81 by the tape winding apparatus 100.

  When the wire 81 is moved toward the rotation center axis Q <b> 1, it is guided by the inner surface 71 of the tapered groove 73 whose groove width decreases along the depth direction, and the wire 81 is accommodated at a deep position of the groove 73. Housed in member 70. Thereby, the clearance gap between the inner surface 71 of the groove | channel 73 and the wire 81 becomes small, and the position of the wire 81 is stabilized at the time of tape winding operation | work. As a result, the tape 90 can be wound around the wire 81 with high accuracy.

  Similarly to the case where the wire 80 having a large diameter size is accommodated in the groove 73, it is desirable that the rotation center axis Q1 and the center axis Q2 coincide when the wire 81 having a small diameter size is accommodated in the groove 73. From this point of view, when the wire 80 having a large diameter size is accommodated in the groove 73, the wire 80 is inserted to a deeper position in the groove 73 than when the wire 81 having a small diameter size is accommodated in the groove 73. The amount of elastic contraction of the member 70 also increases (see FIGS. 3 and 6).

  In the tape winding operation on the wire 81, the subsequent steps (rotation of the rotating body 20 by the rotation drive unit 30, cutting of the tape 90 by the cutting unit 40, etc.) are the same as the tape winding operation on the wire 80 described above. Therefore, explanation is omitted.

  As described above, the tape winding device 100 according to the present embodiment can accommodate the wire 80 having a large diameter size in a deep position of the groove 73 (position close to the rotation center axis Q1) by elastic deformation of the housing member 70. The wire 81 having a small diameter size can be accommodated in a deep position of the groove 73 (position close to the rotation center axis Q1) by being guided by the tapered groove 73. Therefore, in the tape winding apparatus 100, the tape 90 can be wound with high accuracy around a plurality of types of wire rods having different diameter sizes without replacing the housing member 70.

  Moreover, in this embodiment, the accommodating member 70 is comprised with sponge. Since the sponge is porous, it is easily elastically contracted, and the restoring force in the elastically contracted state is small. Therefore, it is easy to accommodate a plurality of types of wire rods having different diameter sizes in the housing member 70 in a close contact state.

<2. Second Embodiment>
A tape winding apparatus according to the second embodiment will be described. 7 and 8 are views showing a state in which the tape 90 is wound around the wire 80 by the tape winding device 100A. 9 and 10 are views showing a state in which the tape 90 is wound around the wire 81 by the tape winding device 100A. In the following description, the same components as those described above are denoted by the same reference numerals, and the description thereof is omitted.

  The tape winding apparatus 100A according to the second embodiment is different from the tape winding apparatus 100 according to the first embodiment in that the tape winding apparatus 100A according to the first embodiment includes a storage member 70a or a storage member 70b instead of the storage member 70 of the first embodiment. . The accommodation member 70 according to the first embodiment has the outer surface 72 bonded to the inner surface 25 of the recess 24, whereas the accommodation members 70 a and 70 b according to the second embodiment are detachable from the recess 24.

  The housing member 70a is, for example, a resin material, and is a U-shaped member in a side view. The housing member 70 a has an inner surface 71 a that can accommodate a wire 80 having a large diameter and an outer surface 72 a that has the same shape as the inner surface 25 of the recess 24. The housing member 70b is the same resin material as the housing member 70a, and is a U-shaped member in a side view. The housing member 70 b has an inner surface 71 b that can accommodate a wire 81 having a small diameter size and an outer surface 72 b that has the same shape as the inner surface 25 of the recess 24. That is, the housing member 70b is a U-shaped member that is thicker than the housing member 70a in a side view.

  When the tape 90 is wound around the wire 80 by the tape winding device 100A, first, the housing member 70a is attached to the recess 24 of the rotating body 20. For example, in a state where the outer surface 72a of the housing member 70a and the inner surface 25 of the recess 24 are in close contact with each other, the positional relationship between the housing member 70a and the recess 24 is fixed using a fixing tool 75 such as a screw.

  After that, as shown in FIG. 7, the wire 80 is moved into the recess 24 toward the rotation center axis Q <b> 1 of the rotating body 20 from the state in which the tape 90 is disposed between the wire 80 and the opening 26 of the recess 24. The Since the accommodating member 70a is provided inside the recess 24, the wire 80 is accommodated in the groove 73a of the accommodating member 70a as shown in FIG. The gap between the inner surface 71 a of the groove 73 a and the wire 80 is smaller than the gap between the inner surface 25 of the recess 24 and the wire 80. Therefore, in 2nd Embodiment, the position of the wire 80 is easy to be stabilized compared with the aspect which accommodates the wire 80 in the recessed part 24, without providing the accommodating member 70a. As a result, the tape 90 can be wound around the wire 80 with high accuracy.

  In the tape winding operation on the wire 80, the subsequent steps (such as rotation of the rotating body 20 by the rotation driving unit 30 and cutting of the tape 90 by the cutting unit 40) are the same as those in the first embodiment, and thus description thereof is omitted. .

  When performing tape winding work on wires having different diameter sizes using the tape winding device 100A, the fixing by the fixing tool 75 such as a screw is released and the accommodating member 70a is removed from the recess 24.

  Next, a flow when the tape 90 is wound around the wire 81 by the tape winding apparatus 100A will be described. In this case, first, the accommodation member 70 b is attached to the recess 24 of the rotating body 20. For example, in a state where the outer surface 72b of the housing member 70b and the inner surface 25 of the recess 24 are in close contact with each other, the positional relationship between the housing member 70b and the recess 24 is fixed using a fixing tool 75 such as a screw.

  Thereafter, as shown in FIG. 9, the wire 81 is moved into the recess 24 toward the rotation center axis Q <b> 1 of the rotating body 20 from the state in which the tape 90 is disposed between the wire 81 and the opening 26 of the recess 24. The Since the accommodating member 70b is provided inside the recess 24, the wire 81 is accommodated in the groove 73b of the accommodating member 70b as shown in FIG. The gap between the inner surface 71 b of the groove 73 b and the wire 81 is smaller than the gap between the inner surface 25 of the recess 24 and the wire 81. Therefore, in 2nd Embodiment, the position of the wire 81 is easy to be stabilized compared with the aspect which accommodates the wire 81 in the recessed part 24, without providing the accommodating member 70b. As a result, the tape 90 can be wound around the wire 81 with high accuracy.

  In the tape winding operation on the wire 81, the subsequent steps (such as rotation of the rotating body 20 by the rotation driving unit 30 and cutting of the tape 90 by the cutting unit 40) are the same as those in the first embodiment, and thus description thereof is omitted. .

  When performing tape winding work on wires having different diameter sizes using the tape winding apparatus 100A, the fixing by the fixing tool 75 such as a screw is released, and the accommodating member 70b is removed from the recess 24.

  As described above, the tape winding apparatus 100 </ b> A of the second embodiment has the plurality of housing members 70 a and 70 b that can be attached to and detached from the recess 24. Therefore, by selecting one housing member from the plurality of housing members 70a and 70b and attaching it to the recess 24, the tape 90 can be wound with high accuracy on a plurality of types of wire rods having different diameter sizes.

  In addition, although 2nd Embodiment demonstrated the aspect in which 100 A of tape winding apparatuses have two types of accommodating members 70a and 70b from which a shape differs, even if 100 A of tape winding apparatuses have three or more types of accommodating members. Alternatively, the tape winding apparatus 100A may have a plurality of types of housing members having different elements (for example, materials) other than the shape. The attachment / detachment of each housing member to / from the recess 24 may be performed manually by an operator or automatically by a robot or the like.

<3. Modification>
Although the embodiment has been described above, the present invention is not limited to the above-described embodiment, and various modifications can be made.

  As described in the first embodiment, the elastic member housing member may be configured to be detachable from the recess 24 as described in the second embodiment.

  FIG. 11 is a schematic configuration diagram illustrating a tape winding apparatus 100B according to a modification. The tape winding apparatus 100B further includes a sheet member 76 (for example, a nonwoven fabric) provided along the groove 73 in addition to the components of the tape winding apparatus 100 according to the first embodiment. Further, the sheet member 76 is more slidable than the housing member 70 with respect to the tape 90. For example, the sheet member 76 is provided on the entire inner surface 71 of the housing member 70. This prevents the inner surface 71 of the housing member 70 from rubbing directly with the non-adhesive surface 94 of the tape 90 wound around the wire 80 during the tape winding operation, and the housing member 70 is not easily worn.

  Moreover, although 1st Embodiment demonstrated the aspect which the whole groove 73 of the accommodating member 70 was a taper shape where a groove width becomes small along a depth direction, the groove | channel of an accommodating member is a groove | channel along a depth direction. The taper part which becomes small in width may be partially included. In this case, if the tapered portion is provided on the opening 26 side of the concave portion 24, the wire can be smoothly inserted into the concave portion 24 by the guide of the tapered portion.

  Moreover, although 1st Embodiment demonstrated the aspect in which the accommodating member 70 was sponge, the accommodating member may be comprised with elastic members other than sponge.

  Moreover, in 2nd Embodiment, about the wire diameter larger than the wire 80, you may insert in the recessed part 24 of the state which removed the accommodating members 70a and 70b, and may perform a tape winding operation | work.

  Although the present invention has been described in detail, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention. The configurations described in the above embodiments and modifications can be appropriately combined or omitted as long as they do not contradict each other.
