Description

  The present invention relates to a direction changing device incorporated in a transport device mainly composed of a track rail and a mobile body that transports an object to be transported by being suspended and supported by the track rail. The present invention relates to a direction changing device that changes the direction of a moving body from one track rail to another track rail.

  At production sites such as factories, the product is completed through a number of production processes, so a hanger rail is suspended through each of these processes and transported to a moving body that is suspended and supported by this hanger rail. A method of transporting semi-finished products or parts as objects may be employed.

  However, depending on the circumstances of the production site, there are usually various routes to be transported, and the transport routes are not a single line, and many are used as needed. Therefore, many track rails are suspended depending on the route. In that case, it becomes necessary to transfer from the track rail to another track rail. That is, when moving the moving body on the track rail from upstream to downstream, if the upstream track rail and the downstream track rail are different rails, a direction changing device is interposed between them, The rail is branched from the upstream rail to a desired downstream rail, thereby changing the direction or changing the course of the moving body traveling on the track rail. Here, upstream and downstream are the positions before and after the moving body changes track rails and the distinction between these rails.

  For example, the direction changing device employs a method in which the moving body that has traveled on the upstream rail is transferred to another downstream rail by being arranged at the intersection of the track rails.

In the direction changing apparatus 100 described in Patent Document 1, as shown in FIG. 25, a rotating body 101 arranged at an intersection of rails 110 places a moving body 120 that has traveled on a certain rail 110, and has a predetermined angle. Is moved to another rail 110 by the rotation of.
Japanese Patent Laid-Open No. 2-108776

  However, such a rotating body 101 narrows the gap between the rail 110 and the rotating body 101 as much as possible so that the moving body 120 can be smoothly transferred from the rail 110 to the rotating body 101 (or vice versa). There is a need. Therefore, the entrance of the rotating body 101 from the rail 110 is formed in an arc-shaped end surface 101a centering on the rotating shaft 131, and the rail side connection port connected to this is also shown in FIG. Furthermore, it is an end face 110a on the arc.

  However, such rails are arranged on various routes according to the circumstances of the site, and the length adjustment is cut according to the respective arrangements. Therefore, the cut surface at that time becomes a connection surface with the rotating body. Since this connection surface is a planar end surface, it must be processed again into an arc-shaped end surface. However, it is troublesome to rework the cut surface every time it is cut.

  Alternatively, when the existing rail is rearranged due to the circumstances of the production site, the end face of the newly recut rail must be reworked into an arc shape.

  Further, the rotating body is not limited to the rotating body having the form as shown in Patent Document 1, and various forms of rotating bodies are provided, thereby providing convenience in accordance with the actual situation of the installation site.

  The present invention has been made in order to solve the above-described problems. Even if the end surface of the rail connected to the rotating body (hereinafter referred to as a rotating body) is not arcuate, the connection with the rotating body is excellent. Thus, it is an object of the present invention to provide a direction changing device according to various modes in which the rails of the moving body and the rotating body can be smoothly boarded and exited, and further, the convenience according to the actual situation of the installation site is provided.

  In order to solve the above problems, a direction change device according to claim 1 of the present application includes a track rail that forms a track, and a moving body that transports an object to be transported by being suspended and supported by the track rail. This is a direction changing device for the moving body incorporated in the conveying device. And it has a rotation body supported so that horizontal rotation is possible, and a rail part provided in the rotation body for making it continue to an end of the track rail, and the rail portion is a track rail of a continuous destination. It is characterized in that an advancing and retreating operation is possible.

According to a second aspect of the present invention, in the first aspect of the present invention, the horizontal rotation axis is provided on an extension of the width center line of the track rail.

  According to a third aspect of the present invention, in the second aspect of the present invention, the rail portion includes two rails arranged in series, and both ends of the rail portion are connected to the track rail.

  According to a fourth aspect of the present invention, in the third aspect of the present invention, the continuous portion of the two rails is placed so that one rail can slide on the other rail, and the rail surface according to the previous placement The step between the two rails is provided at a level that allows the moving body to be transferred between the two rails.

According to a fifth aspect of the present invention, in the first aspect of the present invention, a horizontal rotation shaft is provided on a side portion on one end side of the rail portion.

  According to a sixth aspect of the present invention, in the fifth aspect of the present invention, there is provided a connecting member that is connected to the end portion side of the track rail and supports the rotating body so as to be horizontally rotatable. It is possible to select a state in series with the track rail and a state in which the track rail intersects.

The invention according to claim 7 is the trunk rail that forms part of the track in series with the track rail in the invention according to claim 5, wherein the position forms part of the track, and the position that deviates from the track. The main rail is movably provided to select, and the main rail is attached to the main rail to form a part of the track instead of the main rail at a position where the main rail deviates from the track. And a branch rail. The branch rail includes a rotating body and a supporting portion that pivotally supports the rotating body. The supporting portion is attached to one end of the trunk rail, and the rail portion of the rotating body and the supporting portion are connected in series. The branch rail is formed when the arrangement is difficult.

  Invention of Claim 8 is a case where the track rail of the continuous part of a rail part is provided in different height in invention of Claims 1-5, Comprising: A rotary body is the track rails. It is characterized in that it can be moved up and down between heights.

  The invention described in claim 9 is characterized in that, in the invention described in claim 8, the rotating body is vertically hung up and down by a rotating portion that rotates up and down around a horizontal rotation axis. To do.

  A tenth aspect of the invention is characterized in that, in the first to ninth aspects of the invention, the rail portion is mounted on a roller provided on the rotating body so as to be able to advance and retreat.

  The invention according to claim 11 is characterized in that, in the invention according to claims 1 to 10, the rail portion is urged toward the track rail of the continuous destination and the backward operation is performed by the operation of the advance / retreat handle. To do.

  According to the first aspect of the present invention, when the rotating body is rotated, the rail portion is retracted in the centripetal direction with respect to the rotating shaft, thereby avoiding a collision between the track rail and the rail portion. In addition, when the rail portion is desired to be connected to the track rail, it can be connected without a gap by advancing in the centrifugal direction. Further, when the track rail is laid, the connection with the rail portion of the rotating body is satisfactorily achieved even with the flat cut surface cut to a predetermined length.

  According to the second aspect of the present invention, since the rotation axis of the horizontal rotation is provided at the intersection of the center line of the track rail, it is easy to adjust the arrangement relationship between the track rail to be connected and the direction changing device. is there.

  According to the third aspect of the present invention, since the rail portion can be advanced and retracted at both ends in the diameter direction of the rotating body, connection to the rail is possible at two points of the rotating body.

  According to the fourth aspect of the present invention, the two rail portions are continuous in the vicinity of the center of the rotating body, and one rail portion can be slid onto the other rail portion even when both of them are moved forward and backward. Therefore, the advance / retreat operation can be performed without any trouble. Further, even when the moving body is passed from one side of the rotating body to the other through the center, it is possible to suppress the backlash at the time of movement due to the level difference at the continuous portion.

  According to the invention described in claim 5, since the rail part rotates with its one end side as a rotation axis, the working space and the structure of the apparatus accompanying the rotation are different from those of claim 2, and are different. It can respond to needs. For example, even when the upstream and downstream track rails have a corner-like arrangement relationship, only one side of the rotating shaft serves as a work space, so that the operation space for changing the direction can be saved. In addition, since the rail portion may collide with the track rail only on the other end side (centrifugal side) of the rail portion, the rail portion may be advanced and retracted only on the other end side, and the configuration is simplified accordingly. .

  According to the sixth aspect of the present invention, it is possible to easily form a track that can be selected between a case where the track rail is straight in the middle of a straight line and a case where the track rail is bent in one direction and proceeds to another track. For example, when it is desired to form a track in a T shape.

  According to the seventh aspect of the invention, as in the case of the sixth aspect dependent on the fifth aspect, it is possible to select a case where the track rail goes straight in the middle of a straight line and a case where the track rail is bent in one direction and proceeds to another track. The track can be easily formed. In addition to this, when connecting to a track that advances to another track, a branch rail is connected in series to the track rail instead of the main rail, and when the moving body moves to the branch rail, the main rail is moved to be in series with the track rail. To make it happen. Thereby, rotation of a branch line rail and connection operation to another rail can be performed in a state where a discontinuous portion is eliminated from the track.

  According to invention of Claim 8, the connection between the track rails from which height differs is attained.

  According to the ninth aspect of the present invention, when the connection with the track rail is made between the top position and the bottom position of the vertical rotation, a simple lifting mechanism is provided. In addition, the connection position of the rail portion with the track rail can be selected at an arbitrary rotation position. For example, the rotating body is vertically suspended from the rotating part. At the position where the hanging point on the rotating part side is horizontal with the rotation axis, the hanging point can be two positions on the left and right. Correspondingly, if there are ends of the upstream and downstream track rails, connections to these can be made.

  According to the tenth aspect of the present invention, since the rail portion can be advanced and retracted with a smooth movement with little friction by the roller, the rail portion can be advanced and retracted well even when the weight of the moving body on the rail portion is large. The

  According to the eleventh aspect of the invention, since the rail portion can be advanced and retracted by operating the advancing / retracting handle, it is possible to perform the operation of retracting when rotating and advancing when connecting with the track rail.

  Next, an embodiment of the direction changing device of the present invention will be described.

  FIG. 1 shows a transfer device 1 including a track rail 10 suspended from a ceiling, a beam, and the like, a moving body 20 suspended and supported by the track rail 10, and an intersection between the track rails 10. It is a figure with the direction change apparatus 2. FIG. As shown in FIG. 2, the transport device 1 has four track rails 10 arranged vertically at an angle of 90 degrees, and a direction changing device 2 is provided at the intersection.

  As shown in FIG. 3, the track rail 10 is a C-shaped tube having a square cross section, and an opening groove 12 is provided in a rectangular lower surface portion 11 of a horizontally suspended C-shaped tube. . The two left and right rail sides 13 of the opening groove 12 form a running surface of the wheel described below.

  The moving body 20 mainly includes a wheel base 22 provided with wheels 21 that ride on the two rail sides 13 and a moving body main body 23 that is provided so as to hang from the wheel base 22, and is moved by hand. It is supposed to be.

  The direction changing device 2 includes a rotating body 31 supported so as to be horizontally rotated by a vertical shaft 30 provided at an intersection of the four track rails 10, and a rail portion 32 provided on the rotating body 31. The main structure.

  The rotating body 31 has long side plates 33 in parallel in the left-right direction. The rotating body 31 has a circular hole 40 formed in a rotating support plate 41 (see FIG. 2) provided above the rotating body 31. Tilt is suppressed. As shown in FIG. 4, a rotating roller 34 provided above both ends of a long rotating body 31 is supported on the peripheral edge of the circular hole 40 and can be rotated while receiving this support. Because. When the center of gravity of the moving body 20 is biased, it may be difficult to prevent the rotating body 31 from being tilted by the rotating shaft 30 alone. However, the rotation provided at both ends of such a rotating body 31 may be difficult. The roller 34 prevents tilting.

  Further, on one side plate 33 of the rotating body 31, a rotating operation bar 35 (see FIG. 2) made of a pipe material provided close to and parallel to the rotating shaft 30 is suspended. Rotating body 31 is rotated by turning by hand. Specifically, the advance / retreat handle 36 described below also serves as a turning handle for turning.

  That is, an advance / retreat handle 36 by a grip handle is attached to the turning operation rod 35 so that the advance / retreat operation of the rail portion 32 described below can be performed. The advance / retreat handle 36 also serves as a rotation handle as described above.

  A roller 37 is connected to the side plate 33 of the rotating body 31 along both sides of the side plate 33 along the lower side of the side plate 33 (see FIG. 5). The roller 37 is used for the track rail 10. Two rails 32a and 32b made of the same C-shaped tube are arranged in series to form a rail portion 32. As shown in FIG. 6, one rail 32a is formed by extending only the rail side 32a ′, and this rail side 32a ′ is the other rail 32b. It is mounted on the top so as to be slidable. In that case, the tip of the rail side 32a 'is formed in a loose slope shape, so that the rail surface 32s eliminates the step with the other rail portion 32b.

  Note that the continuous portion is not limited to the above, and another method may be used. As shown in FIG. 7, both rails 32a and 32b are formed with concavo-convex rail sides 32a 'and 32b' so that they can slide. The rail surfaces 32sa and 32sb may be substantially flush with each other.

  These two rails 32 are both biased in the centrifugal direction of the rotating body 31 and are normally in a position protruding from the side plate 33 as shown in FIG. 5, and hold the advance / retreat handle 36 described above. By the operation, as shown in FIG. The two rails 32a and 32b advance and retract simultaneously by operating the advance / retreat handle.

  The method of using this direction changing device is as follows.

  First, the moving body 20 on which an unillustrated object to be transported is pushed by hand and travels on the upstream track rail 10. When the moving body 20 comes to the end of the track rail 10, it stops once. Next, the rotating operation rod 35 is rotated with one hand (if necessary, the rotating body 31 is rotated together with the other hand), and the rail portion 32 continues to the end of the track rail 10 on which the moving body 20 has traveled. Adjust the angular position as follows.

  At this time, the advancing / retreating handle 36 is simultaneously clamped with one hand for gripping the rotating operation rod 35, and the rail portion 32 is moved backward. In this way, even when the rail portion 32 is set to an angular position that is continuous with the end of the track rail 10, the end portions of the rail portion 32 and the track rail are separated from each other. Absent. When the angular position is determined, the advancing / retreating handle 36 is released, and the rail portion 32 biased in the centrifugal direction is advanced to contact the terminal end of the track rail 10, thereby, as shown in FIG. A connection to is made.

  In this state, the moving body 20 once stopped is moved to the rotating body 31 side and placed. When the vehicle is placed, the wheel 21 of the moving body 20 passes through the continuous portion between the rail portions 32. Even in this case, the vehicle can be smoothly placed by the rail surface with few steps.

  The moving body 20 thus placed is rotated together with the rotating body 31 (see FIG. 2) and rotated so as to be connected to the track rail 10 on the downstream side. When rotating, the advance / retreat handle 36 is squeezed and the rail portion 32 is moved backward as before. The moving body 20 is on the rail portion 32, and the weight combined with the object to be conveyed is applied to the rail portion 32. However, since the rail portion 32 itself is placed on the roller 37, the weight is applied. But you can move forward and backward smoothly.

  In this way, the rotating body 31 rotated while holding the advance / retreat handle 36 and retracting the rail portion 32 is rotated to the position of the track rail 10 on the downstream side and operated in the same manner as when it was put on. Then, the moving body is lowered onto the track rail 10 and travels toward the necessary next stroke.

10 to 13 show an embodiment of the direction change device 40 according to claims 5 and 6.
The direction changing device 40 includes a rotating body 41, a connecting member 42 that supports the rotating body 41 so as to be horizontally rotatable, and an advancing / retreating operation unit 44 that performs an advancing / retreating operation of a rail portion 43 provided on the rotating body 41. Have. Further, a square pipe 45 for suspending the direction changing device 40 from the ceiling or the like is welded to the upper surface of the connecting member 42.

As shown in FIG. 13, the connecting member 42 is a ring-shaped member obtained by cutting a C-shaped pipe into a short shape. As shown in FIG. 14, the connecting member 42 has a size and shape into which the track rail 46 (the C-shaped pipe) can be inserted. is doing.

In the rotating body 41, left and right side plates 47 form a skeleton. As shown in FIG. 12 as viewed from above, the same short-cut short tube member 48 used for the connecting member 42 is used as the side plate 47. These side plates 47 are connected to each other so as to be sandwiched between each other, thereby forming a skeleton of the rotating body 41. Then, one end of the side plate 47 is arranged so that the short tube member 48 and the connecting member 42 are connected in series, and a rotating shaft is provided on one of the continuous side surfaces 47a so that the connecting member pivotally supports the rotating body. ing. As shown in FIG. 12, the front and rear short tube members 48 are provided with a rail portion 43 made of a C-shaped tube that is thinner than the short tube member 48 so as to be inserted into the short tube member 48. At that time, the rail portion 43 is formed by connecting two rails 43a and 43b in series with each other as shown in FIG. In the rail portion 43, the rail 43a on one end side (connecting member side) is a fixed rail, but the other end side (front end side) is a movable rail 43b that can be moved forward and backward. The two rails 43a and 43b are spaced apart from each other. FIG. 15 is a diagram when the movable rail on the other end side is retracted, and the movable rail 43b is drawn toward the fixed rail 43a to be in the retracted position.

Further, by rotating the rotating body 41, the relationship with the track rail 46 can be in a series state as shown in FIG. 14 and a crossing state as shown in FIG. . Further, at the time of this rotation, a support wheel 51 for supporting the other end side is provided above the other end side, and is rotated on an arc-shaped support rail described later. .

  As shown in FIG. 10, the advancing / retreating operation unit 44 includes a parallel bar 52 sized to be gripped by a hand provided in parallel to the side plate 47, an advancing / retreating handle 53 by a grip handle provided on the parallel bar, a movable rail A guide bar 55 that is attached to 43b through an L-shaped plate 54 and moves forward and backward, a guide plate 56 having a guide hole through which the guide bar 55 is inserted, and a movable rail 43b that moves backward when the handle 53 is held. A cable 57 for transmitting the pulling operation as much as possible, and a coil spring 58 inserted through the guide rod 55 for returning the movable rail 43b to the advanced position before retreating when the pulling operation is released. When the handle 53 is gripped, the movable rail 43b at the position shown in FIG. 12 is pulled back by the cable 57 and retracted like the movable rail 43b shown in FIG. When the handle 53 is released, the state returns to the state shown in FIG.

  FIG. 17 is an explanatory view of the state in which the above-described direction changing device 40 is incorporated into the transport device 1.

  As shown in the figure, the direction changing device 40 is provided at the intersection of two track rails, and is suspended from a ceiling or the like by a square pipe 45 welded to the upper surface of the connecting member 42. And the track rail 46 is inserted and connected to the connection member 42 of this direction change apparatus 40, and it will be suspendedly supported with the rotation body. The connecting member 42 may be supported by the track rail 46 by being connected to the track rail 46 without being suspended by the square pipe 45. In this case, it is necessary that the end of the track rail 46 has a support strength sufficient to withstand the support of the rotating body 41.

  Further, a support rail 59 formed in an arc shape of about 90 degrees is also suspended, so that a support wheel 51 provided on the other end side of the rotating body 41 can travel. As shown in FIG. 18, the cross section of the support rail 59 hangs below the travel plate 60 and the travel plate on which the support wheels travel, and the moving body does not fall from the other end of the rotational body 41 when rotating. The cover plate 61 is formed in an arc shape of about 90 degrees.

  In the method of using the direction changing device 40 of this embodiment, when the moving body is transferred from the upstream track rail 46a shown in FIG. 17 to the downstream track rail 46b, first, the rotating body at some position is used. Is appropriately rotated to the position shown in FIG. 19 (the same position as FIG. 17) in series with the upstream track rail 46a. At this time, since the other end side of the rotating body 41 is free, there is no need to consider such as hitting the track rail as in the first embodiment, so there is no need to move the movable rail back and forth. Further, since the fixed rail on one end also changes from the state shown in FIGS. 11 and 13 to the closed state, there is no problem of colliding with a continuous partner as described in the problem.

  When the rail portion 43 of the rotating body 41 is thus continued in series with the upstream track rail 46a, the moving body 20 is pulled from the track rail 46a to the rotating rail portion 43 by hand. It should be noted that a position fixing means at the serial position may be provided so that the rotating body 41 does not rotate during the transfer, or it may be simply pressed by hand. Here, the advancing / retreating handle 53 is lightly grasped together with the parallel bar 52 to prevent rotation, and the moving body 20 is transferred to the rotating body 41. For example, the parallel bar 52 is grasped together with the advance / retreat handle 53 with the right hand, and the moving body 20 is grasped with the left hand, and the transfer operation to the rotating body 41 is performed. When the vehicle is transferred, the forward / backward handle 53 of the right hand is squeezed as it is, and the movable rail 43b is moved backward while being rotated 90 degrees to bring it to the position shown in FIG. In the middle of the rotation, even if the moving body 20 is swung to the other end side by centrifugal force due to the rotation, the other end side is covered with the cover plate 61 provided a little apart. It will not drop out.

  After rotating 90 degrees in this way and rotating to the downstream track rail 46b position, the grip of the advance / retreat handle 53 is loosened, the movable rail 43b is advanced by the bias of the coil spring 58, and the track rail 46b and the movable rail 43b are moved. Connect. As a result, even when the moving body 20 is transferred to the track rail 46b, the rail is unbroken and there is no influence because it is minute.

  In addition, you may provide the direction change apparatus 40 as follows as an Example of Claim 5. FIG. That is, although it demonstrates using FIG. 17, in this figure, a rotation body is replaced and arrange | positioned for every connection member at the one end side and the other end side. If it carries out like this, the other end (movable rail side) of a rotary body will face an upstream track rail, and this will become a transfer port of a mobile body. In this state, it is turned 90 degrees and lowered onto the track rail downstream. Therefore, it is necessary to arrange the downstream track rail so as to be moved to the right rear in FIG. In this example, the other end performs both of getting on and off, but in the previous example, it gets on from one end side and gets off from the other end side.

  In the above description, upstream and downstream are convenient, and the reverse operation / use method described above may be used.

  Furthermore, although the above embodiment assumes the case where the track has a corner shape and passes through the corner, it is not so. Instead, it is desired to branch into a track that bends at right angles in the middle of the track that extends linearly. Of course it can be used in some cases.

  In addition, when the track is continuous with the adjacent work room, there is the following usage. In other words, if there is a sliding window or door between the adjacent work rooms, this window or door is opened and the track is arranged so as to pass through the open window or door. . And in the location which passes a window or a door, it installs so that the rotation body similar to the said Example may become a part of track | orbit. Normally, the track extends between the own room and the adjacent work room in this way.

  When the user wants to close the window or door, the rotating body can be turned to create a track cut, and the sliding window or door can be tightened across the track cut.

  For example, if you want to enlarge the work area, open the window, connect the rotating body to the adjacent track to pass this window, expand the work area, and when working in your own room, rotate the rotating body to open the window. Is closed. For example, at the time when the air conditioning is effective, it is possible to connect the track with the neighbor or change only to the own room according to changes in circumstances such as narrowing or widening the work place.

21 to 23 are schematic views of an embodiment of the invention of the direction changing device 70 according to claims 5 and 7.
This direction changing device 70 forms a track as a part of the track rail 71, and a main rail 72 and a branch rail 73 having the same length are provided in parallel. And it can move so that it may become a part of one of these orbits.

That is, the main rail 72 forms a part of the track in series with the track rail 71, and a position that forms a part of the track (FIG. 21) and a position that deviates from the track (FIG. 22) should be selected. It is provided to be movable.

A mounting portion 74 for mounting the branch rail 73 is provided on one end side of the main rail 72, and the branch rail 73 is mounted by the mounting portion 74. The branch rail 73 is provided with a support portion 75 fixed to the mounting portion 74 and a rotating body 76 pivotally supported by the support portion 75. Further, the mounting portion 74 and the support portion 75 are the same members as the connecting member 42 of the second embodiment, and a C-shaped tube that becomes the rail portion 77 is inserted into the mounting portion 74. In the figure, the rail portion 77 of the rotating body 76 is configured such that when the rail portion 77 is parallel to the main rail 72, the rail portion 77 and the support portion 75 are connected to form a branch rail 73. As shown in FIG. 22, the branch rail 73 forms a part of the track in place of the main rail 72 at a position where the main rail 72 is off the track.

Although it is a method of use, a track is constituted by the branch rail 73 as shown in FIG. 22, and the moving body 20 that has moved from, for example, the track 71a upstream is placed on the rail portion 77 of the rotating body. Then, it is moved again to the position shown in FIG. 21 and the track is returned from the branch rail 73 to the main rail 72. In this state, the rotating body 76 is rotated and, as shown in FIG. 23, is continued to the downstream rail 71b arranged to cross the upstream rail 71a. The rail portion 77 of the rotator 76 has a fixed rail and a movable rail arranged in series as in the second embodiment. When the rail portion 77 is connected to the downstream track rail 71b, the movable rail is moved backward as in the second embodiment. , And then advance after continuing. The advance / retreat operation for that purpose may be provided similarly to the advance / retreat operation unit of the second embodiment.
Moreover, the above is description based on a conceptual diagram, and the structure for mechanical strength should actually be added. In addition, the technology of Japanese Patent Application No. 2000-240917 by the applicant of the present application can be applied to the configuration of the trunk rail that forms part of the track or deviates from the track.

FIG. 24 shows a schematic diagram of an embodiment of the invention of the direction changing device 80 according to claims 8 and 9.
