Description

  The present disclosure relates to a floating transfer apparatus.

  2. Description of the Related Art Conventionally, there is a levitation type conveying apparatus that ejects air from a large number of air holes formed on a conveying surface and moves a conveyed object while floating on the conveying surface. Patent Document 1 discloses a transport device that causes an intermediate body to be a flexible disk to be transported later and causes the transported surface to slide on the transport surface by inclining a transport surface having a large number of air holes. doing.

  On the other hand, instead of transporting the transported object directly floating on the transport surface as in the transport apparatus disclosed in Patent Document 1, the transported object is held in a separately provided transport container, A transport device that floats and moves the transport container holding the transported body on the transport surface is also conceivable.

Japanese Utility Model Publication No. 5-42233

  However, when the transport container holding the transported object is lifted and moved on the transport surface, it is necessary to consider the following points. In a state where the transported body is held in the transport container, it is rare that the positions of the center of gravity of the transported body and the transport container coincide with each other, and usually the positions of the center of gravity of each other are biased. Therefore, due to this bias, the transport container holding the transported object may rotate around the direction perpendicular to the transport surface as the central axis while moving on the transport surface. When such rotation occurs, the posture of the transport container is not fixed at the exit position where the transport container reaches after movement. Therefore, for example, an extra process such as rotating the object to be transported at the exit position with respect to the object to be transported with directivity may occur.

  Therefore, an object of the present disclosure is to provide a transfer device that is advantageous for steadying the posture of a transfer container that holds a transfer target.

  A conveyance device according to one embodiment of the present disclosure is in a plane that intersects a conveyance path having a conveyance surface having gas ejection holes and an axis along the conveyance direction with respect to the conveyance surface as an intersection line, and is a space on the conveyance surface A guide having a guide surface opposed to the guide, the guide being disposed on one side end of the transport surface along the transport direction, and the transport surface is inclined downward toward the guide .

  Moreover, in said conveyance apparatus, a guide surface is good also as what has a gas ejection hole. Further, the transport surface may be inclined downward from the upstream side in the transport direction toward the downstream side.

  According to the present disclosure, it is possible to provide a transfer device that is advantageous for steadying the posture of the transfer container that holds the transfer target.

  Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Here, the dimensions, materials, or other specific numerical values shown in the following embodiments are merely examples, and do not limit the present disclosure unless otherwise specified. In addition, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present disclosure are not illustrated. Further, in each of the following drawings, the Z axis is taken in the vertical direction, the X axis is taken in the plane perpendicular to the Z axis in accordance with the transport direction, and the Y axis is taken in the direction perpendicular to the X axis.

  FIG. 1 is a perspective view illustrating a configuration of a transport apparatus 10 according to an embodiment of the present disclosure. The transport device 10 ejects gas from a number of gas ejection holes 12b formed on the transport surface 12a, and moves on the transport surface while the transport container 60 holding the transport target W is floated on the transport surface 12a. It is a floating type conveying device.

  First, the transport container 60 that is directly transported by the transport device 10 and the transported body W that is held by the transport container 60 and transported together will be described. FIG. 2 is a perspective view showing the transport target W and the transport container 60.

  FIG. 2A is a perspective view showing the conveyed object W. FIG. Articles that can be the object of the transport target W are not particularly limited, including the shape and material thereof. Here, as an example, it is assumed that the transport target W is formed of a steel material, and the shape of the transport target W is a cylinder.

  FIG. 2B is a perspective view showing the transport container 60. The shape of the transport container 60 is, for example, a rectangular parallelepiped. The transport container 60 has a slot 60b on one plane side. The slot 60b has a bottom surface 60c that allows the end surface of the transported body W to come into contact, and can hold at least a part of the transported body W. Various materials can be used for the transport container 60. Furthermore, although explained in full detail below, the conveyance container 60 slides on the conveyance surface 12a by gas levitation. Further, while the transport container 60 is floating on the transport surface 12a, the side surface of the transport container 60 also receives gas from another angle. Therefore, in the transport container 60, for smoother sliding, it is desirable that the lower surface and the four side surfaces opposite to the plane on which the slot 60b is formed be a smooth surface with small waviness.

  FIG. 2C is a perspective view showing the transport container 60 in a state where the transport target W is held. The transported object W being held in the transport container 60 means a state in which at least a part of the transported object W is inserted into the groove 60b and placed as shown in FIG. Say. Therefore, the opening shape of the groove hole 60b is in contact with the inner surface of the groove hole 60b regardless of the direction of translation when the inserted object to be transferred W is slightly translated while being in contact with the conveyance container 60. It has a shape in which translation in the same direction is restricted. In FIG. 2, the center of gravity C1 of the transport target W and the center of gravity C2 of the transport container 60 are clearly shown, and the relationship between them will be described later.

  Next, the configuration of the transport apparatus 10 will be described. The transport apparatus 10 includes a transport path 12, a guide 14, and a support base 16.

  The conveyance path 12 is a flat plate having a conveyance surface 12a extending in accordance with the conveyance direction. The transport container 60 can slide while floating on the transport surface 12a. The conveyance surface 12a has a large number of gas ejection holes 12b for ejecting compressed gas toward the outside. Although not shown, the gas ejection hole 12b is connected to a gas supply device such as a pump for supplying gas. The gas ejected from the gas ejection hole 12b is air. However, a gas other than air may be used. The specifications of the gas supply device, the shape of the gas ejection holes 12b, and the like are selected in consideration of the ascent capability that can stably float the transport container 60 holding the transport target W.

  The guide 14 is a flat plate having a guide surface 14a extending in a direction along the transport direction. The guide surface 14a is in a plane intersecting the transport surface 12a with the axis along the transport direction as an intersection line CL with respect to the transport surface 12a, and faces the space on the transport surface 12a (see FIG. 4). Moreover, the guide surface 14a has many gas ejection holes 14b which eject a compressed gas toward the exterior. Similarly to the gas ejection holes 12b formed on the transport surface 12a, the gas ejection holes 14b are also connected to a gas supply device to obtain gas ejected from the gas ejection holes 12b. However, the specifications of the gas supply device, the shape of the gas ejection holes 14b, and the like should be separated so that they do not come into contact with the guide surface 14a when the transport container 60 holding the transport target W approaches the guide surface 14a. Is selected in consideration of the separation ability to the extent possible.

  FIG. 3 is a diagram illustrating the posture of each component of the transport device 10 with respect to the transport direction. FIG. 3A is a plan view of the transport device 10 as viewed from above in the Z direction. FIG. 3B is a side view of the transport device 10 as viewed from the Y direction plus side. The Z direction is the upper side of the vertical direction. Further, the X direction and the Y direction are directions orthogonal to the Z direction.

  In the transport apparatus 10, as an example, the transport direction of the transport container 60 is assumed to be from the minus side in the X direction toward the plus side. In this case, the conveyance path 12 is inclined downward from the upstream side to the downstream side in the conveyance direction. Specifically, the height position in the Z direction in the transport path 12 is higher in the X direction minus side position where the transport container 60 is carried in than in the X direction plus side position where the transport container 60 is carried out. . Here, as shown in FIG.1 and FIG.3 (b), let the inclination angle of the conveyance direction of the conveyance path 12 with respect to a horizontal surface be (alpha) (degree).

  FIG. 4 is a diagram for explaining the posture of each component of the transport apparatus 10 in the direction perpendicular to the transport direction, corresponding to the IV-IV cross section in FIG. The conveyance path 12 is inclined downward from the side end portion 12d on the side where the guide 14 is not installed, toward the side end portion 12c on the side where the guide 14 is installed, on both side ends of the conveyance surface 12a. ing. Specifically, the height in the Z direction of the transport path 12 is such that the position of the side end portion 12d on the plus side in the Y direction where the guide 14 is not installed is on the minus side in the Y direction where the guide 14 is installed. It is higher than the position of the side end 12c. Here, as shown in FIGS. 1 and 4, an inclination angle in a direction perpendicular to the conveyance direction of the conveyance path 12 with respect to the horizontal plane is β (°).

  Further, as shown in FIG. 4, the angle formed between the transport surface 12a and the guide surface 14a is γ (°). As will be described in detail below, gas is ejected from the gas ejection holes 14b formed in the guide surface 14a toward the side surface of the transport container 60 on the transport surface 12a. Therefore, the guide surface 14 a needs to be installed at an angle that can face the side surface of the transport container 60. Therefore, considering the ease of design or installation when the guide 14 is installed in the conveyance path 12, it is desirable to set the angle γ = 90 (°), but in reality, it is strictly 90 °. There is no need. For example, when the shape of the transport container 60 is different from the rectangular parallelepiped as illustrated above, and the side surface of the transport container 60 is a plane intersecting the support surface supported by the transport surface 12a, the shape of the guide surface 14a You may change the angle | corner (gamma) to match | combine with the side surface facing the guide surface 14a.

  In addition, although the conveyance path 12 and the guide 14 are drawn as one body in each drawing, in practice, they may be formed as one body or may be formed by combining separate ones. Absent.

  The support 16 supports the conveyance path 12 and the guide 14 at a desired height position from the floor surface on which the conveyance device 10 is installed. The support 16 includes, for example, a base 18 that is placed on the floor surface, and leg portions 20 that stand on the base 18 and hold the conveyance path 12 and the guide 14. Furthermore, the leg portion 20 is, for example, a first leg portion 20a positioned on the minus side in the X direction, which is upstream of the transport direction of the transport path 12, and a first leg portion positioned on the plus side of the X direction, which is downstream of the transport path 12. 2 legs 20b. As described above, in the transport device 10, the transport path 12 is higher in the upstream height position in the transport direction than in the downstream height position. Therefore, the height position of the first leg portion 20a is set to be higher than the height position of the second leg portion 20b. The specific height positions of the first leg portion 20a and the second leg portion 20b are the lengths of the first leg portion 20a and the second leg portion 20b themselves, and the height of the transport path 12 is a desired height. As such, it may be set in advance. Alternatively, although not shown, each of the first leg portion 20a and the second leg portion 20b may have a height adjustment mechanism, and the height may be adjusted appropriately by the height adjustment mechanism. With such a configuration, the first leg portion 20a and the second leg portion 20b can be referred to as a first inclination adjusting portion that adjusts the inclination angle α of the conveyance path 12 in the conveyance direction.

  Further, the support base 16 has a second inclination adjustment for inclining the conveyance path 12 at an inclination angle β on a part of the first leg portion 20a and the second leg portion 20b in a plane perpendicular to the conveyance direction. Part 22 is included. The second inclination adjusting unit 22 has a predetermined size, and may be a so-called spacer that adjusts the height by replacing it with an appropriate size, or adjusts the height appropriately. It may be a height adjustment mechanism that can be used.

  In addition, the transport device 10 includes a carry-in unit 40 that carries the transport container 60 into the transport path 12 and a carry-out unit 50 that transports the transport container 60 that has been transported through the transport path 12.

  The carry-in unit 40 is disposed on the upstream side of the transport path 12 and delivers the transport container 60 onto the transport surface 12a. For example, the carry-in unit 40 may be connected to the upper end portion 12e in the conveyance direction of the conveyance path 12 and deliver the conveyance container 60 to the conveyance surface 12a in accordance with the conveyance direction. However, in the present embodiment, the carry-in unit 40 is connected to the side end 12d perpendicular to the conveyance direction of the conveyance path 12, and the conveyance container 60 from a position perpendicular to the conveyance direction with respect to the conveyance surface 12a. The case of carrying in is illustrated.

  The carry-in unit 40 includes, for example, a first mounting unit 42 having a mounting surface 42a on which the transport container 60 before transporting the transported object W is placed, and a desired first mounting unit 42 from the floor surface. 1st support part 44 supported in a height position. Here, a guide 14 is installed at one side end 12c of both side ends that are perpendicular to the transport direction of the transport path 12. Therefore, as shown in FIG. 3A, the carry-in portion 40 is disposed in the vicinity of the other side end portion 12d where the guide 14 is not installed.

  Further, the transport surface 12a is inclined at an inclination angle α with respect to the horizontal plane in the transport direction. Therefore, as shown in FIG. 3B, the carry-in unit 40 matches the inclination angle α of the conveyance surface 12 a with the inclination angle α of the conveyance surface 12 a, so that the placement surface 42 a and the conveyance surface 12 a are aligned. It is desirable to match the surface position in the transport direction. On the other hand, the conveyance surface 12a is inclined at an inclination angle β with respect to the horizontal plane in a direction perpendicular to the conveyance direction. Therefore, as shown in FIG. 4, the carry-in unit 40 adjusts the inclination angle in the direction perpendicular to the conveyance direction of the placement surface 42a to the inclination angle β of the conveyance surface 12a, so that the placement surface 42a and the conveyance surface It is desirable to match the surface position in a direction perpendicular to the conveying direction with 12a. At this time, it is desirable that the gap G1 between the carry-in unit 40 and the conveyance path 12 is as small as possible.

  The carry-in part 40 may further include a wall part 46 for suppressing the drop of the transport container 60 from the placement surface 42a. In particular, since the mounting surface 42a is inclined so as to be lowered from the upstream side to the downstream side in the transport direction, as illustrated in FIGS. 3A and 3B, the transport of the first mounting unit 42 is performed. It is desirable to be installed at the side end portion 42b on the downstream side in the direction.

  On the mounting surface 42a, the transport container 60 holding the transport target W may be manually placed, or may be placed automatically from an external delivery mechanism (not shown). Further, the shape of the first mounting portion 42 may be, for example, a long plate such that the mounting surface 42a extends further to the other. Further, the mechanism for moving the transport container 60 to the transport surface 12a side on the mounting surface 42a is not particularly limited. For example, a belt conveyor type mechanism driven by an electric motor may be employed, or a spring A pressure type mechanism using an elastic body such as an air cylinder or the like may be employed.

  The first support portion 44 includes, for example, a base 48 placed on the floor surface and a leg portion 49 that stands on the base 48 and holds the first placement portion 42. The specific height position or posture of the first support portion 44 may be set in advance so that the length of the leg portion 49 itself matches the height and posture of the transport path 12. Alternatively, although not shown, the leg portion 49 may have a height and posture adjustment mechanism, and the height and posture may be adjusted as appropriate by the height and posture adjustment mechanism.

  The carry-out unit 50 is disposed on the downstream side of the conveyance path 12 and receives the conveyance container 60 from the conveyance surface 12a. For example, the carry-out unit 50 may be connected to the lower end portion 12f in the conveyance direction of the conveyance path 12 and receive the conveyance container 60 in accordance with the conveyance direction with respect to the conveyance surface 12a.

  The carry-out unit 50 includes, for example, a second placement unit 52 having a placement surface 52a on which the transported container 60 after transporting the transported object W is placed, and the second placement unit 52 from the floor. And a second support portion 54 that supports the height position. Here, in the carrying-in part 40, the 1st mounting part 42 was inclined so that the mounting surface 42a and the conveyance surface 12a might fit. On the other hand, since the unloading unit 50 simply receives the transport container 60 transported along the transport surface 12a, the mounting surface 52a of the second mounting unit 52 is shown in FIG. As shown, it may be a horizontal plane. At this time, it is desirable that the gap G2 between the carry-out unit 50 and the conveyance path 12 is as small as possible.

  The carry-out part 50 may further have a wall part 56 for preventing the transport container 60 from dropping from the placement surface 52a. In particular, even if the transport container 60 that has slid on the transport surface 12a lands on the placement surface 52a, it may move further in the transport direction due to inertial force. Therefore, it is desirable that the wall portion 56 be installed at the side end portion 52b on the downstream side in the transport direction of the second placement portion 52, as shown in FIGS. 3 (a) and 3 (b).

  For example, the transport container 60 that has reached the placement surface 52a may be automatically moved to another transport location by an external receiving mechanism (not shown) while holding the transport target W.

  The second support portion 54 includes, for example, a base 58 placed on the floor surface and leg portions 59 that are erected on the base 58 and hold the second placement portion 52. The specific height position or posture of the second support portion 54 may be set in advance so that the length of the leg portion 59 itself matches the height and posture of the transport path 12. Alternatively, although not shown, the leg portion 59 may have a height and posture adjustment mechanism, and the height and posture may be appropriately adjusted by the height and posture adjustment mechanism.

  Next, the operation according to this embodiment will be described.

  FIG. 5 is a plan view showing a series of movements of one transport container 60 on the transport path 12. In FIG. 5, a black arrow indicates a path along which the transport container 60 moves on the placement surface 42 a of the carry-in unit 40. On the other hand, a white arrow indicates a path along which the transport container 60 moves on the transport surface 12 a of the transport path 12.

  First, as the preparation stage of the transport apparatus 10, two inclination angles α and β related to the posture of the transport path 12 are set. The inclination angles α and β can be appropriately changed according to the material and shape of the transport target W, the request for transport time, and the like.

  Next, in a state where the gas ejection holes 12b of the conveyance surface 12a and the gas ejection holes 14b of the guide surface 14a are ejecting gas, the conveyance container holding the conveyance target W on the placement surface 42a of the loading unit 40. 60 is pushed toward the transport surface 12a. Here, the mounting surface 42a and the transport surface 12a are in the same position in two directions, ie, the transport direction and the direction perpendicular to the transport direction. That is, the mounting surface 42a and the transport surface 12a are on the same plane. Here, the same plane does not only indicate a completely identical plane, but allows slight differences in height and inclination angles α and β in portions close to each other. Further, the gap G1 between the carry-in unit 40 and the conveyance path 12 is set to be as small as possible. Accordingly, the transport container 60 can smoothly move from the placement surface 42a of the carry-in unit 40 to the transport surface 12a of the transport path 12 as indicated by a two-dot chain line in FIG.

  Further, as described above, it is also conceivable that the carry-in unit 40 is connected to, for example, the upper end part 12e of the conveyance path 12 in the conveyance direction. However, in such an arrangement, the entire length of the transfer device 10 is increased particularly in the transfer direction, and thus, for example, it is easy to be restricted in layout when the transfer device 10 is installed in a factory. On the other hand, in this embodiment, since the carrying-in part 40 is arrange | positioned at the side edge part 12d side of the conveyance path 12, it is parallel with the conveyance path 12 in a conveyance direction. Therefore, the transport apparatus 10 becomes compact as a whole, and as a result, it is difficult to receive restrictions on the layout.

  Next, the transport container 60 pushed onto the transport surface 12a floats on the transport surface 12a. Here, first, the transport surface 12a is inclined so as to descend from the upstream side to the downstream side in the transport direction. Thereby, the conveyance container 60 goes to the carrying-out part 50 naturally along a conveyance direction. Furthermore, the conveyance surface 12a is secondly arranged in the direction perpendicular to the conveyance direction from the side end portion 12d on which the carry-in portion 40 is installed to the other side end portion on which the guide 14 is installed. It inclines so that it may fall to the 12c side. As a result, the transport container 60 naturally moves toward the guide surface 14 a of the guide 14. As a result, the transport container 60 gradually approaches the guide surface 14a while moving in the transport direction.

  At this time, as shown in FIG. 5, even if the transport container 60 is pushed out onto the transport surface 12a in a state where the side surface is not parallel to the guide surface 14a, These side surfaces are parallel to the guide surface 14a. Here, in the present embodiment, gas is also ejected from the gas ejection holes 14b of the guide surface 14a. Therefore, as shown in FIG. 4, the transport container 60 approaching the guide 14 side does not come into contact with the guide surface 14a, and is maintained at a substantially constant interval, as shown in FIG. Head. Accordingly, after the transport container 60 is loaded onto the transport surface 12a, the posture is quickly defined according to the guide surface 14a, and the transport container 60 is transported to the unloading unit 50 in a state where the posture is constant.

  In addition, even if the conveyance container 60 approaches the guide 14 side and contacts the guide surface 14a and receives a certain amount of frictional force, the guide surface 14a does not necessarily have a gas ejection hole if the sliding is not greatly affected. It is not necessary to have 14b.

  Then, the transport container 60 that has been transported in a certain posture reaches the placement surface 52 a of the carry-out unit 50. Such a flow of transport is the same for all transport containers 60 transported by the transport device 10. Therefore, the transport container 60 is mounted on the mounting surface 52a in approximately the same posture every time, and the posture variation of each time can be minimized. As a result, for example, when a receiving mechanism (not shown) automatically receives the transport container 60 on the placement surface 52a, the receiving mechanism fails to receive it or receives it in an unstable posture in which the transport target W is likely to fall. It can be avoided.

  On the other hand, as a comparative example, a case is considered in which a transport container 60 holding a transport target W is transported in a floating transport device having a horizontal transport surface. Here, referring to FIG. 2 (c), the size of the slot 60 b formed in the transport container 60 is larger than the cross-sectional shape of the transport target W so that the transport target W can be easily held. Is also set larger. Accordingly, the transported body W held in the transport container 60 can move slightly within the groove 60b of the transport container 60, so that the center of gravity C1 of the transported body W and the center of gravity C2 of the transport container 60 are There is no constant match. Therefore, while the transport container 60 holding the transport target W slides while floating on the horizontal transport surface, the axis perpendicular to the transport surface is the central axis due to the deviation of the center of gravity. Rotate as As a result, since the posture of the transport container 60 being transported is not determined, the posture of the transport container 60 after transport is not determined. Thereby, when the receiving mechanism automatically receives the transported container 60 after being transported, a situation may occur in which the receiving mechanism fails to receive or the transported object W is received in an unstable posture that is likely to fall.

  Next, the effect by this embodiment is demonstrated.

  First, the transport apparatus 10 according to the present embodiment includes a transport path 12 having a transport surface 12a having gas ejection holes 12b. Moreover, the conveying apparatus 10 is provided with the guide 14 which exists in the plane which cross | intersects the axis along a conveyance direction with respect to the conveyance surface 12a as a crossing line, and has the guide surface 14a which opposes the space on the conveyance surface 12a. The guide 14 is installed on the side of one side end 12c of the transport surface 12a along the transport direction. Further, the transport surface 12 a is inclined downward toward the guide 14.

  According to the transport apparatus 10 according to the present embodiment, the transport container 60 holding the transport target W is quickly moved to the guide 14 side after being transported onto the transport surface 12a. As a result, the posture of the transport container 60 during transport becomes constant according to the guide surface 14a, and the posture of the transport container 60 after unloading is also made steady. Therefore, for example, it can be avoided that the receiving mechanism fails to receive the transport container 60 after being carried out or receives the transported object W in an unstable posture that is likely to fall.

  Further, since the posture of the transport container 60 is constant while being transported on the transport surface 12a, dropping of the transport target W due to a change in the posture of the transport container 60 during transport is also suppressed. Further, as a comparative example, when the conveyance surface is a horizontal surface, the movement of the conveyance surface in a direction different from the conveyance direction due to the rotation of the conveyance container on the conveyance surface is considered in advance. It is necessary to increase the dimension in the width direction perpendicular to the transport direction. On the other hand, in the present embodiment, the transport container 60 carried onto the transport surface 12a quickly approaches the guide 14 side, and the approximate position during transport is determined, so that the transport direction of the transport surface 12a is perpendicular. Thus, the dimension in the width direction can be further reduced. Therefore, the conveying apparatus 10 becomes compact as a whole. As a result, the transfer device 10 is not easily restricted by the layout.

  Furthermore, since the transport device 10 does not require a complicated mechanism as a mechanism for making the posture of the transport container 60 constant, the manufacturing cost of the transport device 10 can be reduced and maintenance can be facilitated.

  Moreover, in the conveying apparatus 10 which concerns on this embodiment, the guide surface 14a has the gas ejection hole 14b.

  According to the transport apparatus 10 according to the present embodiment, even if the transport container 60 holding the transport target W approaches the guide 14 side on the transport surface 12a, it does not come into contact with the guide surface 14a and has an approximately constant interval. Glide while maintaining. Therefore, since the conveyance container 60 does not receive a frictional force from the guide surface 14a during sliding, it can smoothly slide even if it approaches the guide 14 side.

  Furthermore, in the transport apparatus 10 according to the present embodiment, the transport surface 12a is inclined downward from the upstream side in the transport direction toward the downstream side.

  According to the transport apparatus according to the present embodiment, the transport container 60 slides along the transport direction with its own weight after being transported to the transport surface 12a. Therefore, the transport apparatus 10 does not need to be provided with a mechanism for separately sliding the transport container 60 floating on the transport surface 12a in the transport direction. As a result, the manufacturing cost of the transfer device 10 can be reduced, and maintenance can be facilitated.

  For example, it may be difficult to incline the transport surface 12a downward from the upstream side in the transport direction toward the downstream side due to restrictions on the installation of the transport apparatus 10 in the factory. In that case, the transport apparatus 10 may be provided with a mechanism for sliding the transport container 60 in the transport direction while setting the inclination angle α to 0 (°). The mechanism for sliding the transport container 60 in the transport direction is not particularly limited.
