  As described above, the on-floor transfer device described above is intended to prevent the fall of dust and dirt from the ceiling or rail like an overhead conveyor. However, there was a slight shaking of the conveyed product.

  As for such swaying of the transported object, there is no problem when it is a normal transport, that is, when transporting from one processing base to the next processing base. In the case of transporting in a region where a painting process such as painting is performed (this is referred to as a coating processing section), there is a problem that unevenness may occur on the painted surface.

  The present invention has been made in view of the above-mentioned points. The purpose of the present invention is to attenuate the vibration of the traveling body as much as possible when traveling in the area of the spray painting processing section, It is providing the conveying apparatus which can suppress a shake.

  Therefore, the present invention provides a transport rail that forms a transport path on the floor, a traveling body that moves while being restricted in the track by the transport rail, and a transported object that is erected on the traveling body to support the transported object. In the transport device provided with the support column, the traveling body is provided on a main body portion having a predetermined length in the traveling direction and a lower portion near the front and rear ends of the main body portion, and travels along the transport rail. A wheel, an axle projecting in a direction perpendicular to the longitudinal direction of the main body portion above the main body portion, and a rolling member supported at the tip of the axle, the transport rail being painted A regulation rail for regulating the rolling position of the rolling member in a section area is provided.

  According to the above configuration, when the traveling body travels along the conveyance rail in the section where the traveling body is painted (coating section), the rolling member is regulated by the regulation rail. Combined with the state regulated by the traveling rail, the posture of the traveling body can be stabilized, and the posture of the props for transported articles standing on the main body can also be stabilized.

  In the above-described device, the rolling member may be provided at both ends of the axle on both sides of the main body of the traveling body.

  According to the above configuration, the traveling body can be stabilized by restricting the two rolling members arranged on both sides of the main body of the traveling body by the regulating rails that regulate the rolling members. In the case where the restriction rail is provided only on either one of the both sides of the traveling body according to the environment in which the traveling body moves, the rolling members are arranged on both sides, so at least one rolling member is It is also possible to regulate by the regulation rail.

  Moreover, in the said device, it is set as the structure which the said control rail is arrange | positioned at the both sides which the said traveling body drive | works in the area | region of the section processed by painting, and controls the rolling member provided in the both ends of the said axle simultaneously. it can.

  With the above configuration, when the state in the area of the painting processing section is allowed, two rolling members provided on both sides of the main body of the traveling body can be simultaneously controlled, and the posture of the traveling body is further stabilized. be able to.

  Furthermore, in the said device, the said rolling member can be set as the structure formed by the rolling holding body supported by this main-body part above the main-body part of the said traveling body.

  According to the said structure, the support | pillar for conveyance objects will be stabilized further by restrict | limiting the position which approaches a conveyance object rather than the main-body part of a traveling body. In particular, the main body portion of the traveling body is regulated by the traveling wheels and the traveling rail, and the rolling holding body present at a position away from the main body portion is regulated by the rolling member and the regulating rail. This also contributes to the stability of the traveling body due to restrictions at several points apart.

  Moreover, in the said device, while the said rolling holding body is comprised with a elongate rod-shaped member, it shall be the structure provided so that the longitudinal direction might become parallel to the longitudinal direction of the main-body part of the said traveling body. Can do. In the case of such a configuration, since the rolling holding body moves in the same manner as the main body of the traveling body, the regulation rail can be provided in parallel to the traveling rail.

  Further, in the above device, one end of the rolling holding body is rotatably supported by the main body of the traveling body, and the traveling body is rotatably provided with one end supported by the main body. A rotating arm and a hooking portion that is provided so that the vicinity of the tip of the rotating arm can be hooked, and the hooking portion hooks an axle that supports the rolling member. can do.

  According to the above configuration, in a state in which the rolling member is regulated by the regulation rail, the weight of the conveyed product is supported by one end (rotation side) of the rolling holding body and the other end where the rolling member is provided. Thus, the moving state of the rolling part holder is stabilized. When the movement state of the rolling holding body is stabilized, the posture of the conveyed product support column is also stabilized.

  Moreover, in the said device, it can be set as the structure which can be latched, having a play by the arc shape larger than the diameter of the said axle shaft which should be latched, in the latching part of the said rotation arm.

  According to the said structure, when a rolling member is controlled by a control rail, it becomes possible to raise a rolling member rather than the latching | locking part of a rotation arm. That is, since it is possible to move the axle within the range of play provided on the latch member, by adjusting the height of the regulation rail so as to lift the rolling member within the range of play, It is possible to lift the axle within the range of play and share the weight acting on the rolling holding body between the rolling member and the regulating rail.

  According to the present invention, since the rolling member provided in the main body portion of the traveling body is regulated by the regulation rail, the posture of the traveling body is stabilized, thereby suppressing the struts for the conveyance object from vibrating, It becomes possible to stabilize the conveyed product installed in the upper end of the support | pillar. In particular, in the case of a configuration in which the rolling member is provided on the rolling part holding body, the rolling member is regulated at a position away from the main body part of the traveling body, and by stabilizing the posture of the rolling holding body, It can suppress that a conveyed product vibrates.

  Further, in a state in which the rolling holding body is configured to be rotatable and the rolling member is supported by the regulation rail, the weight acting on the rolling holding body is reduced between the rotating portion side and the rolling member side. Therefore, it is possible to stabilize the moving posture of the rolling holding body, and thereby suppress the swinging of the transported object column and the transported object installed at the upper end thereof.

  Therefore, by installing these transport devices in the painting processing section, even if spray coating is performed while traveling in the area of the coating processing section, it is possible to realize coating on a transported object with less shaking, and to improve the coating surface. Can be finished.

It is a perspective view which shows the outline of embodiment of this invention. (A) is explanatory drawing of the state before a rolling member is controlled by the control rail, (b) is explanatory drawing of the state where the rolling member was controlled by the control rail. It is explanatory drawing of the state which clarified the state by which the rolling member is controlled by the control rail. It is explanatory drawing which shows the modification of embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an outline of this embodiment of the present invention. As shown in this figure, the present embodiment is configured by a transport rail 1 and a traveling body 2 that moves along the transport rail 1. Furthermore, the traveling body 2 includes a main body 3, a rolling holder 4 disposed above the main body 3, and a transport column 5 erected on the rolling holder 4. Traveling wheels 31 and 32 are provided at the lower part so that they can travel inside the transport rail 1. Further, a support column 6 is erected on the main body 3 of the traveling body 2, and a U-shaped rotation shaft support 61 is formed at the upper end thereof.

  The rolling holding body 4 is arranged in parallel to the main body 3 of the traveling body 2, and one end of the rolling holding body 4 is provided as a turning end, and a turning shaft 41 is provided. By supporting the rotation shaft 41 by the rotation shaft support portion 61, the rolling holder 4 can be rotated. Further, an axle 42 is provided at the other end of the rolling holder 4, and rolling members 7a and 7b are provided at both ends, respectively. Note that the axis of the axle 42 is directed in a direction orthogonal to the longitudinal direction of the rolling holding body 4 (same as the longitudinal direction of the main body portion of the traveling body 2), and penetrates the rolling holding body 4. Both ends of the rolling holding body 4 protrude on both sides. Accordingly, the rolling members 7 a and 7 b provided at both ends are installed at the same height on both sides of the rolling holding body 4.

  Here, as described above, the traveling wheels 31 and 32 provided in the main body 3 of the traveling body 2 travel inside the traveling rail 1, and the traveling wheels 31 and 32 always travel by the traveling rail 1. The position will be regulated. A drive chain 11 is arranged in parallel in the vicinity of the transport rail 1, and a part (pendant 12) of the drive chain 11 is moved by a driving device (not shown) so that the traveling body The main body 3 of 2 is locked and the driving force for the traveling body 2 is transmitted.

  On the other hand, the rolling holding body 4 is located above the traveling wheels 31 and 32, and the regulation rails 8 a and 8 b for regulating the rolling holding body 4 are arranged above the conveyance rail 1. Is. Each of the regulation rails 8a and 8b is formed in a U-shaped cross section, and the rolling members 7a and 7b can roll on the inner bottom surface. In this rolling state, since the inner upper surfaces of the regulation rails 8a and 8b are located immediately above the rolling members 7a and 7b, the rolling members 7a and 7b It is regulated by 8a and 8b.

  Therefore, when the regulation rails 8a and 8b are installed in a predetermined section, that is, a painting processing section, the rolling members 7a and 7b are regulated by the regulation rails 8a and 8b when transporting the inside of the section. Therefore, the posture of the rolling holder 4 is stabilized. Thereby, it can suppress that the support | pillar 5 for the conveyed product erected by the rolling holding body 4 and the conveyed product installed in the upper end can be shaken.

  Such regulation rails 8a and 8b can be configured to be disposed as a pair on both sides of the rolling holding body 4 so as to simultaneously regulate the rolling members 7a and 7b, but are provided on only one of them. It can be configured. This is because one of the rolling members 7a and 7b is regulated by one of the regulation rails 8a and 8b, so that the position of one end of the rolling holder 4 can be regulated.

  In the present embodiment, as shown in FIG. 1, the axle 42 is latched by the latching portion 91 of the L-shaped rotating arm 9. By this latching, the rolling holding body 4 is maintained in parallel with the main body 3 of the traveling body 2 in a normal state. This rotating arm 9 is for holding the posture of the conveyed product constant when the conveyance path as shown in Patent Document 3 is inclined. Therefore, in this embodiment, it is not necessary to use the L-shaped rotation arm 9, but in order to correspond to the inclination of the conveyance path as described above, it is preferable to include the mechanism.

  In the drawing, each of the rails 1, 8 a, 8 b and the drive chain 11 is only a part, but the transport rail 1 and the drive chain 11 are installed throughout the transport path, and the regulation rail 8 a, 8b is arranged continuously in the painting section.

  Here, the operation | movement aspect of this embodiment is demonstrated. FIG. 2 is a diagram showing an operation mode. FIG. 2A shows a state before the rolling member 7a is regulated by the regulating rail 8a, and FIG. 2B shows a state where the rolling member 7a is regulated by the regulating rail 8a. In addition to the regulation rail 8a, the other regulation rail 8b (FIG. 1) paired with the regulation rail 8a may be provided. However, here, a configuration in which only one regulation rail 8a is provided is illustrated. And will be described below on the assumption.

  As shown in FIG. 2 (a), before the rolling member 7a is regulated by the regulating rail 8a, the latching portion 91 of the rotating arm 9 latches the axle 42, whereby the rolling holder 4 Is maintained parallel to the main body 3 of the traveling body 2. In this state, when the traveling body 2 is driven (pulled) by the drive chain 11 (FIG. 1), the traveling body 2 moves along the transport rail 1. Of the traveling wheels 31 and 32 of the traveling body 2, the front wheel 32 is provided with a locked portion 33 so that the pendant 12 of the drive chain 11 can be locked, and the locked portion 33 has a pendant. The traveling body 2 is pulled in a state in which the is engaged. The direction of movement of the traveling body 2 at this time is the right direction (arrow direction) in the figure.

  In this way, when the traveling body 2 travels along the transport rail 1 and reaches the coating processing section in a state where the rolling member 7a is not regulated at all, the rolling member 7a starts to be regulated by the regulating rail 8a. It becomes.

  When the rolling member 7a is regulated by the regulation rail 8a, the rolling member 7a is located inside the regulation rail 8a as shown in FIG. 2 (b). Here, the latching portion 91 of the rotating arm 9 releases the latching of the axle 42. The latch release of the axle 42 of the latch portion 91 is performed within the range of play provided between the two. That is, by configuring the diameter of the arcuate portion of the latching portion 91 larger than the diameter of the axle 42, the axle 42 is actually latched while having the appearance that the latched state is continued. It rises slightly from the inner surface of the portion 91.

  A clear state in which the rolling member 7a is regulated by the regulation rail 8a is shown in FIG. As shown in this figure, in a state where the rolling member 7a is regulated by the regulating rail 8a, the rotating arm 9 does not substantially hook the axle 42 and supports one end of the rolling holding body 4. There is no state.

  Therefore, based on FIG. 3, the stability of the posture of the traveling body 2 and the rolling holding body 4 will be described. In the traveling body 2, the traveling wheels 31 and 32 of the main body 3 travel inside the traveling rail 1. Thus, the basic position is regulated by the traveling rail 1. The rolling member 7 a is located inside the regulation rail 8 a different from the transport rail 1 at a position away from the traveling wheels 31 and 32. As a result, when the running body 2 is swayed, if the swaying is in the front-rear direction, as long as the position of the rotation shaft 41 of the rolling holder 4 does not move up and down, It can be avoided to transmit the vibration to the rolling holding body 4. Further, when the left and right sway is generated with respect to the traveling body 2, the rolling member 7a cannot be moved in the left-right direction (perpendicular to the paper surface in the drawing) by the restriction rail 8a. It is possible to avoid transmitting the shaking to the rolling holder 4.

  As described above, even when the traveling body 2 vibrates due to an impact or the like during traveling, it is possible to suppress the occurrence of the shaking of the rolling holding body 4 due to the vibration. Therefore, the occurrence of shaking is also suppressed in the conveying support 5 provided on the rolling holder 4, and as a result, the conveyed object is prevented from shaking.

  Embodiments of the present invention are as described above, but various forms can be made without departing from the spirit of the present invention. FIG. 4 shows a modification of the above embodiment. As shown in this figure, a support member 109 that supports the axle 42 may be provided in place of the rotating arm 9. In the case of such a configuration, as described above, the posture of the conveyed product when the conveyance path is inclined is not stabilized, but when moving in the region of the coating processing section, the rolling member is moved by the regulation rail 8a. It is possible to regulate 7a. This is because the support member 109 can support the axle 42 at the upper end thereof, and the axle 42 is configured to freely move upward.

  As described above, if the rolling holding body 4 is pivotally supported at one end and the other end (the axle 42) can be moved up and down, the same operation and effect as the above-described embodiment can be obtained. It can be obtained, and is not limited to the above-described embodiment and modification.

  Moreover, the said rolling holding body 4 is good also as a structure which is not rotatable. In this case, the main body portion 3 and the rolling holding body 4 of the traveling body 2 are integrally formed, but the rolling body is separated from the traveling wheels 31 and 32 by the regulation rail 8a different from the traveling rail 1. By restricting the moving member 7a, the traveling wheels 31 and 32 and the rolling member 7a are three-dimensionally restricted, so that the posture of the traveling body 2 can be prevented from changing. is there. And the rolling member 7a can be further stabilized by largely projecting from the rolling holding body 4. Similarly to the configuration as described above, it is possible to adopt a configuration in which the rolling holding body 4 is provided in close contact with the main body 3 of the traveling body 2. In this case, if the position where the rolling member 7a is provided is upward from the main body 3 and protrudes laterally from the main body 3, the traveling body 2 is stabilized in the traveling posture.
