Description

  The present invention relates to a positioning device for a traveling body.

  An example of this type of positioning device for a traveling body is a traveling type acoustic reflector positioning device.

  The acoustic reflector prevents the performance sound from being absorbed by curtains installed on the stage when performing performances without using acoustic equipment on a stage such as a multipurpose hall or theater, and reflects the performance sound to the audience. And provide an acoustic space that can reach the audience efficiently.

  In order to build an acoustic space, sound reflectors should be provided on the stage, in front of the stage, and on both sides of the stage sleeves.

  Therefore, the multipurpose hall incorporates a mechanism to move the acoustic reflector so that it can be stored and deployed according to the performance. As a mechanism for moving the acoustic reflector, there is a traveling acoustic reflector as described above, in addition to a mechanism that hangs a wire from the ceiling of the hall and lowers the acoustic reflector on the stage as necessary.

  In the case of a traveling-type acoustic reflector, a plurality of reflectors of different sizes can be stored in a nesting state, and can be run on rails laid in the depth direction of the stage. When the acoustic reflector is not used, each reflector is nested and stored in the storage pace at the back of the stage, and when used, each reflector is moved to the front of the stage to construct an acoustic space.

  In such an acoustic reflector, the smallest reflector is a box with a reflector on the ceiling and front and sides, and the other reflector is a gate with reflectors on the ceiling and sides. Thus, the depth of the acoustic space can be changed (see, for example, Patent Document 1).

  Each reflector includes a wheel that travels on a rail laid on the floor and a motor that drives the wheel. The motor can be driven to reciprocate between the stage and the storage space. Further, the reflector is provided with a lever-type limit switch, and a dog is provided in the vicinity of the rail on which the reflector travels and at the stop position at the time of small knitting to rotate the lever when contacting the lever.

  When the reflecting plate travels to the stop position where the dog is provided, the lever is rotated by the dog, the limit switch opens the motor drive circuit, and the acoustic reflecting plate can be automatically stopped. As described above, the positioning device is configured to include a dog, and can position the reflecting plate, which is a traveling body, at a predetermined stop position.

  When the acoustic reflector is composed of three large, medium, and small reflectors X, Y, and Z, as shown in FIG. 11, in the small organization, the large reflector X is arranged in front of the stage, and other reflectors except for this are arranged. The Y and Z are stacked in a nested manner when viewed from the stage sleeve side, and are arranged on the back side of the stage with respect to the large reflector X to reduce the depth of the acoustic space. On the other hand, in the large organization, as shown in FIG. 12, all the reflectors X, Y, and Z are shifted in the stage depth direction to increase the depth of the acoustic space.

  Thus, since the stop position of the small reflector Z is different between the small knitting and the large knitting, if a dog is provided at the stop position of the large knitting of the small reflector Z, the small knitting behind the stage from the stop position of the small knitting The small reflecting plate Z cannot move to the small knitting stop position.

  Therefore, the dog is not provided at the stop position of the large knitting of the small reflector Z, and the operator manually operates the motor to stop the small reflector Z at the stop position of the large knitting visually. Such manual operation is complicated, and fine adjustment of the position of the small reflector Z is required to stop the small reflector Z at an appropriate stop position. It had been.

  Therefore, the present invention was devised to improve the above-mentioned problems, and the object of the present invention is to provide a traveling body that can easily position the traveling body at the stop position without requiring high skill from the operator. A positioning device is provided.

  In order to achieve the above-described object, the positioning device for a traveling body of the present invention is detected by a switch provided on the traveling body, and there is a dog provided at a stop position of the traveling body under the travel line of the switch. It can be attached and detached at the stop position.

  Therefore, in this positioning device, if the dog is installed, the traveling body can be automatically positioned and stopped at the stop position, and the passage of the traveling body can be allowed by removing the dog.

  Therefore, according to this positioning device, a traveling body that needs to be positioned and stopped at a plurality of positions can be automatically positioned and stopped by selecting an arbitrary position among the plurality of positions as a stop position.

  Further, in the positioning device for a traveling body according to claim 2, the dog has an inclined surface capable of contacting the switch lever at one end, and the front and rear are positioned by being inserted into a bracket provided below the travel line of the switch. Can always be attached to the bracket in the correct orientation. Furthermore, since the dog can always be mounted in the correct orientation, it is possible to always realize an appropriate use state of the switch that is a lever type limit switch.

  Furthermore, in the positioning device for a traveling body according to claim 3, the bracket allows insertion of a bolt provided on a base on which a rail on which the traveling body travels is laid, and has a long hole along the rail laying direction. Bolted to the base. Therefore, since the mounting position of the bracket to the stop position can be adjusted in the rail laying direction, the stop position at which the dog is attached and detached can be adjusted in the traveling direction of the traveling body, and the stopping position for positioning the traveling body is set to the optimum position. it can.

  In the traveling body positioning device according to claim 4, the dog and the bracket are connected by the wire, and the length of the wire is set to a length in which the dog does not contact the floor when the dog is suspended from the bracket by the wire. Has been. In this way, even if the dog is dropped from the bracket, it will not touch the floor and will not be damaged, and if the wire is pulled up, the dog below the base can be easily taken out and attached to the bracket .

  In the traveling body positioning device according to the fifth aspect, the traveling body is a reflector that can travel in the depth direction of the stage. In addition, among the storage position stored at the back side of the stage, the small knitting position arranged on the front side of the stage, and the large knitting position arranged between the storage position and the small knitting position, the stop position of the traveling body is large. The dog is detachable as a knitting position. In this way, even if the stop position of the reflector is different between the small knitting and the large knitting, it is possible not only to stop the reflector to the large knitting position by providing a dog at the middle large knitting position but also to reflect by removing the dog Movement of the plate to the small knitting position is allowed. Therefore, even when the reflector is positioned and stopped at the large knitting position, manual operation of the motor by the operator becomes unnecessary, and the work of stopping the reflector visually is eliminated.

  According to the positioning device of the traveling body of the present invention, the traveling body can be easily positioned at the stop position without requiring high skill from the operator.

The present invention will be described below based on the illustrated embodiment. As shown in FIGS. 1 and 2, the traveling body positioning device 1 in the present embodiment uses the reflector 2 of the acoustic reflector RB traveling on the stage S as a traveling body, and has a large knitting position that accommodates a large knitting. The reflecting plate 2 is positioned as a stop position.
<First embodiment>
As shown in FIGS. 1 and 2, the acoustic reflector RB is configured by large, medium, and small reflectors 4, 3, and 2. The small reflecting plate 2 and the large reflecting plate 4 can run on rails 7 and 8 laid on a floor B below the stage S through bases 5 and 6. The front and back of the stage S indicate the front and back of the stage S when viewed from the audience seat A, and the depth direction of the stage S is the front and rear direction of the stage S when viewed from the audience A. The frontage direction indicates the left and right direction of the stage S as viewed from the audience seat A, and the sleeves of the stage S indicate the left and right ends of the stage S.

  The small reflector 2 as a traveling body rises perpendicularly to the stage S and rises perpendicularly to the stage S along the front direction of the stage S, and stands in the depth direction of the stage S. A pair of side reflectors 22, 23 provided opposite to each other and connected to the left and right of the front reflector 21, and connected to the upper ends of the front reflector 21 and the side reflectors 22, 23 and above the stage S It is box-shaped with the ceiling reflection part 24 installed.

  The middle reflecting plate 3 stands perpendicularly to the stage S, is provided along the depth direction of the stage S, and is connected to a pair of side surface reflecting parts 31 and 32 facing each other, and the upper ends of the side surface reflecting parts 31 and 32. And a ceiling reflecting portion 33 installed above the stage S and configured in a gate shape. The length dimension of the inner side of the side reflecting parts 31 and 32 and the ceiling reflecting part 33 of the middle reflecting plate 3 is set to a size that can be accommodated by nesting the small reflecting plate 2 in the contents. The medium reflector 3 is connected to the small reflector 2 so as to be movable in the depth direction of the stage S. The medium reflector 3 is moved relative to the small reflector 2 by driving a driving source such as a motor (not shown). Thus, it can be reciprocated in the depth direction.

  The large reflector 4 stands upright with respect to the stage S, is provided along the depth direction of the stage S, and is connected to the pair of side surface reflection parts 41 and 42 facing each other, and the upper ends of the side surface reflection parts 41 and 42. The ceiling reflecting portion 43 installed above the stage S is configured in a gate shape. The lengths of the inner side lengths of the side reflecting parts 41 and 42 and the ceiling reflecting part 43 of the large reflecting plate 4 are set to dimensions that can be accommodated by nesting the middle reflecting plate 3 in the contents.

  A storage space G is provided at the back of the stage S, and as shown by the broken lines in FIGS. 1 and 2, when all the reflection plates 2, 3, 4 are stored in the storage space G, the storage space G is small. The reflecting plates 2 and 3 inside are accommodated and stored.

  And when using the acoustic reflector RB, when constructing an acoustic space suitable for a large orchestra, each reflector 2, 3, 4 is arranged as follows. As shown by the solid line in FIG. 1, the large reflector 4 is disposed in front of the stage S when viewed from the audience side, and the small reflector 2 is disposed behind the stage S with a gap from the large reflector 4, The middle reflecting plate 3 is moved to the passenger seat A side with respect to the small reflecting plate 2 so as to be filled between the small reflecting plate 2 and the large reflecting plate 4.

  Moreover, when constructing an acoustic space suitable for a small orchestra, each reflector 2, 3, 4 is arranged as follows. As shown by the solid line in FIG. 2, the large reflector 4 is disposed in front of the stage S when viewed from the audience side, and the small reflector 2 is disposed in the back of the stage S with no gap from the large reflector 4. When viewed from the sleeve of the stage S, the middle reflecting plate 3 is placed so as to overlap the small reflecting plate 2.

  As can be understood from FIGS. 1 and 2, in the arrangement for accommodating a large orchestra, the depth from the passenger seat side end of the large reflector 4 to the front reflector 21 of the small reflector 2 can be increased. Further, in the arrangement for accommodating the small-organized orchestra, the depth from the passenger seat side end of the large reflector 4 to the front reflector 21 of the small reflector 2 can be made shorter than in the case of the large composition. Therefore, in this acoustic reflector RB, an optimal acoustic space can be provided according to the orchestra scale.

  As described above, the small reflector 2 includes the storage position TG in the storage space G in the back of the stage S, the small organization position TS that is on the front side of the stage S and accommodates the small organization, the storage position TG, Stops at the large knitting position TL between the knitting positions TS and accommodates the large knitting orchestra. In the positioning device 1 of this example, the small reflector 2 can be positioned with the large knitting position TL as the stop position.

  As shown in FIG. 3, the small reflector 2 as a traveling body is arranged in parallel with a gap in the front direction of the stage S, and travels on a pair of rails 7 laid along the depth direction of the stage S. . For this purpose, four traveling wheels W that travel on the rail 7 are provided at the lower ends of the side reflecting portions 22 and 23 of the small reflector 2. The four traveling wheels W are rotatably attached to a frame F provided inside the lower ends of the side reflecting portions 22 and 23, arranged side by side along the rail 7, and the two traveling wheels W on the center side are arranged. It is driven by a motor M installed on the frame F. Specifically, a chain C is wound around a sprocket SM driven by a motor M and a sprocket SW provided on the traveling wheel W. When the motor M is driven, the traveling wheel W is rotationally driven and the small reflector 2 is moved. It can be moved in the depth direction of the stage S.

  Further, at the lower end of the frame F, four switches 51, 52, 53, 54 are provided. These switches 51, 52, 53, 54 are lever type limit switches, and are installed on the frame F with the lever side facing downward. The switch 51 is electrically connected to the drive circuit of the motor M so as to decelerate the rotation speed of the motor M when the lever 51a at the tip is tilted rightward in FIG. 3 while the small reflector 2 is moving to the back side of the stage S. It is connected to the. The switch 52 stops the motor M and moves the small reflector 2 to the back side of the stage S when the lever 52a at the tip is tilted rightward in FIG. 3 while the small reflector 2 is moving to the back side of the stage S. Is electrically connected to the drive circuit of the motor M so as to stop the movement of the motor M. The switch 53 is electrically connected to the drive circuit of the motor M so as to decelerate the rotational speed of the motor M when the lever 53a at the tip is tilted to the left in FIG. 3 while the small reflector 2 is moving to the front side of the stage S. It is connected to the. The switch 54 stops the motor M to the front side of the stage S of the small reflector 2 when the lever 54a at the tip is tilted to the left in FIG. 3 while the small reflector 2 is moving to the front side of the stage S. Is electrically connected to the drive circuit of the motor M so as to stop the movement of the motor M.

  As shown in FIGS. 4 and 5, the rail 7 is laid on a floor B below the stage S through a base 5, and the base 5 has a cross section H in which upper and lower flanges 5a and 5b are connected by a web 5c. The lower flange 5b is bolted to the floor B and fixed. In this example, the rail 7 is a flat bottom rail, and the bottom portion is gripped by a plurality of fasteners 60 bolted onto the upper flange 5 a and fixed to the base 5.

  In addition, bolts 61 and 62 can be screwed to a large knitting position TL that is a stop position of the small reflecting plate 2 at the side of the upper flange 5a. 9 is fixed to the base 5.

  As shown in FIGS. 4 to 6, the bracket 9 includes a fixed plate 91 that is provided with a long hole 91 a along the laying direction of the rail 7 and is fixed to the side surface of the flange 5 a, and the flange 9 a from above the fixed plate 91. And a dog mounting plate 92 that is horizontal and extends away from the rail 7. The long hole 91a provided in the fixing plate 91 allows insertion of the screw shafts of the two bolts 61 and 62 that are screwed to the flange 5a with a gap in the laying direction of the rail 7. The length of the long hole 91a in the longitudinal direction is set so that the fixing plate 91 can be moved in the rail laying direction with the bolts 61 and 62 inserted therethrough. The installation position can be adjusted in the depth direction of the stage S.

  The dog mounting plate 92 is provided with two holes 92a and 92b penetrating vertically, and the holes 92a and 92b are circular so that the centers thereof are arranged in the depth direction of the stage S, and the holes The diameter of 92a is smaller than that of the hole 92b.

  The dog 10 is detachably attached to the dog attachment plate 92. When the dog 10 is attached to the bracket 9, the dog 10 is attached to the large knitting position TL. As shown in FIGS. 4 and 5, the dog 10 includes a plate-shaped dog body 10 a and two pins 10 b and 10 c extending from the lower side of the dog body 10 a. And the notch part is provided above the back | inner side of the stage S of the dog main body 10a, and the slope 10d is formed. The pins 10b and 10c are cylindrical, and the diameter of the pin 10b is smaller than that of the pin 10c. More specifically, the pin 10b on the slope 10d side has a diameter that can be fitted into a hole 92a disposed on the back side of the stage S of the dog mounting plate 92 of the bracket 9. The pin 10c on the side opposite to the inclined surface 10d has a diameter that can be fitted into a hole 92b disposed on the front side of the stage S of the dog mounting plate 92 of the bracket 9. In order to attach the dog 10 thus configured to the bracket 9, the pin 10b is inserted into the hole 92a and the pin 10c is inserted into the hole 92b. The pin 10c can be inserted into the hole 92b but cannot be inserted into the hole 92a. Therefore, when the dog 10 is attached to the dog mounting plate 92, the inclined surface 10d of the dog 10 faces the back side of the stage S, and the dog 10 is surely correct to the bracket 9. Mounted in the direction. In other words, if any one of the plurality of pins 10b and 10c can be inserted into only one of the plurality of holes 92a and 92b, the dog 10 is parallel to the rail 7 and is attached to the bracket 9. At this time, if the dog 10 is not in the correct orientation, it cannot be attached to the bracket 9. Therefore, if the above-described conditions are satisfied, the number of pins and holes may be two or more, and the shape is not limited to a round hole. If one pin and hole are desired, the cross-section may be a polygon with an odd cross section and three or more vertices. Even in this case, the dog 10 is parallel to the rail 7 and attached to the bracket 9. In this case, the dog 10 can be attached to the bracket 9 only in the correct direction. The attachment of the dog 10 to the bracket 9 may be performed by a structure other than that using pins and holes. However, if the pins 10b and 10c and the holes 92a and 92b are used, the structure is simplified and the bracket 10 of the dog 10 is attached. Is easy to attach and detach, and the manufacturing cost is low. A structure in which a hole is provided in the dog 10 and a pin is provided in the bracket 9 can also be employed.

  Further, a wire attachment hole 10e penetrating in the horizontal direction is provided below the dog 10 opposite to the inclined surface 10d of the dog body 10a, and is on the front side of the stage S of the fixing plate 91 of the bracket 9 and upward. Also, a wire attachment hole 91b that penetrates the fixing plate 91 horizontally is provided. The wire 11 is connected to the dog 10 and the bracket 9 using these wire attachment holes 10e and 91b. That is, the dog 10 and the bracket 9 are connected by the wire 11. The length of the wire 11 is set to a length that does not interfere with the floor B even when the dog 10 is suspended from the bracket 9 by the wire 11. Therefore, in a state where the dog 10 is removed from the bracket 9, as shown in FIG. 7, the dog 10 is suspended from the bracket 9 by the wire 11, but the dog 10 does not interfere with the floor B. .

  Thus, the traveling body positioning device 1 includes the dog 10, and when the dog 10 is attached to the bracket 9 installed on the base 5, the small reflector 2 as the traveling body travels on the rail 7. The dog 10 is disposed immediately below the travel line through which the switches 53 and 54 pass. When the small reflector 2 travels from the storage space G to the front of the stage S and reaches the large knitting position TL, which is the stop position, the lever of the switch 53 first contacts the slope 10d of the dog 10. When the small reflector 2 further travels before the stage S, the lever 53a of the switch 53 is tilted to the left as shown in FIG. 8, and then the lever 54a of the switch 54 contacts the slope 10d of the dog 10. When the lever 53a of the switch 53 comes into contact with the dog 10 and is tilted, the rotational speed of the motor M is reduced, and the moving speed of the small reflector 2 toward the front side of the stage S is reduced. When the small reflector 2 is thus decelerated and moves to the front of the stage S beyond the position shown in FIG. 8, this time, the lever 54a of the switch 54 is tilted to the left by the dog 10 and the motor M stops. Then, the small reflector 2 stops at the large knitting position TL. Thus, if the switch 54 is a limit switch, the position of the small reflector 2 can be mechanically detected, and the small reflector 2 can be stopped at the large knitting position TL, which is the stop position. Further, if two switches 53 and 54 are used as limit switches, the position of the small reflector 2 is mechanically detected, and the small reflector 2 is decelerated before the stop position and then stopped. The plate 2 can be accurately stopped at the large knitting position TL. In addition, since the dog 10 includes the inclined surface 10d that contacts the levers 53a and 54a, the levers 53a and 54a can be slowly tilted along the inclined surface 10d by the movement of the small reflector 2. As described above, if the dog 10 is provided with the inclined surface 10d contacting the 53a and 54a, the moving speed of the small reflector 2 can be increased, and the moving speed can be increased as the inclination angle of the inclined surface 10d is reduced.

  Since the switch 54 is a limit switch, the lever is brought into contact with the dog 10, the stop position of the small reflector 2 is detected by detecting the presence of the dog 10, and the electric circuit is mechanically opened to open the small reflector 2. Although it can be stopped at the stop position, a non-contact type proximity switch or the like can also be used. That is, a switch that can detect the presence of the dog 10 can be used, and when the proximity switches are provided in the switches 53 and 54, the slope 10d does not have to be provided in the dog 10.

  In this case, the position where the switch 54 detects the dog 10 and stops the small reflection plate 2 is the stop position, and the position where the switch 10 is detachably provided according to the installation position of the switch 54 on the small reflection plate 2. Is adjusted. Note that the switch 53 can be omitted if deceleration before stopping the small reflector 2 is unnecessary.

  Apart from the dog 10, the base 5 is provided with fixed dogs 12 and 13 at the storage position TG and the small knitting position TS of the small reflector 2. Although not shown in detail, the fixed dog 12 installed at the storage position TG has a slope like the dog 10 and is fixedly installed on the base 5 with the slope facing the front side of the stage S. Although not shown in detail, the fixed dog 13 installed at the small knitting position TS has a slope similar to the dog 10 and is fixedly installed on the base 5 with the slope facing the back side of the stage S. .

  When the small reflection plate 2 is moved from the front side of the stage S to the storage space G and the small reflection plate 2 approaches the storage position TG, the lever 51a of the switch 51 provided on the small reflection plate 2 is fixed at the storage position TG. The small reflecting plate 2 decelerates due to contact with the dog 12 and falling down. When the small reflection plate 2 further travels to the back of the stage S, the lever 52a of the switch 52 is tilted, the motor M is stopped, and the small reflection plate 2 stops at the storage position TG.

  When it is desired to move the small reflector 2 to the small knitting position TS, the dog 10 is removed from the bracket 9 in advance. In this state, when the small reflector 2 is moved from the back side of the stage S to the near side from the large knitting position TL, the levers 53a and 54a of the switches 53 and 54 are not tilted by the dog 10 and do not detect the dog 10. The small reflector 2 continues to travel to the front side of the stage S through the large knitting position TL. When the small reflecting plate 2 approaches the small knitting position TS, the lever 53a of the switch 53 provided on the small reflecting plate 2 comes into contact with the fixed dog 13 provided at the small knitting position TS and falls, and the small reflecting plate 2 decelerates. To do. When the small reflector 2 further travels before the stage S, the lever 54a of the switch 54 is tilted, the motor M is stopped, and the small reflector 2 stops at the small knitting position TS.

  In this way, the presence of the switch 54 provided on the small reflecting plate 2 that is a traveling body is detected, and the dog provided below the running line of the switch 54 and at the large knitting position TL (stop position) of the small reflecting plate 2. 10 is attachable to and detachable from the large knitting position TL (stop position). Therefore, in this positioning device 1, if the dog 10 is installed, the small reflecting plate 2 can be automatically positioned and stopped at the large knitting position TL. If the small reflector 2 is not desired to be stopped, the dog 10 may be removed. Therefore, according to the positioning device 1, a traveling body that needs to be positioned and stopped at a plurality of positions can be automatically positioned and stopped by selecting an arbitrary position among the plurality of positions as a stop position. Therefore, the traveling body can be easily positioned at the stop position without requiring high skill from the operator.

  Further, the dog 10 has a slope 10d that can contact the lever 54a of the switch 54 at one end, and the front and rear are positioned by being inserted into the bracket 9 provided below the travel line of the switch 54. Can be mounted in the correct orientation. Furthermore, since the dog 10 can always be mounted in the correct orientation, the proper use state of the switch 54 which is a lever type limit switch can always be realized.

  Further, the bracket 9 allows insertion of bolts 61 and 62 provided on the base 5 on which the rail 7 on which the small reflector 2 travels is laid, and has a long hole 91 a along the laying direction of the rail 7. Therefore, the mounting position of the bracket 9 to the stop position can be adjusted in the laying direction of the rail 7. Therefore, the stop position at which the dog 10 is attached / detached can be adjusted in the traveling direction of the small reflector 2 that is the traveling body, and the stop position for positioning the small reflector 2 can be set to an optimum position.

  The dog 10 and the bracket 9 are connected by the wire 11, and the length of the wire 11 is set so that the dog 10 does not contact the floor B when the dog 10 is suspended from the bracket 9 by the wire 11. Yes. In this way, even if the dog 10 is removed from the bracket 9, the dog 10 does not touch the floor B without being damaged, and if the wire 11 is pulled up, the dog 10 below the base 5 can be easily removed. It can be taken out and attached to the bracket 9. A wire attachment hole 10e for attaching the wire 11 to the dog 10 is provided below the inclined surface 10d of the dog body 10a, and a wire attachment hole 91b for attaching the wire 11 to the bracket 9 is provided on the front side of the stage S of the fixing plate 91. When provided on the upper side, the wire 11 is not easily disturbed when the dog 10 is attached to the bracket 9, and the length of the wire 11 can be shortened.

In this traveling body positioning device 1, a reflecting plate (small reflecting plate 2) capable of traveling in the depth direction on the stage S is used as the traveling body, and the storage position TG is stored on the back side of the stage S, the stage Of the small knitting position TS arranged on the front side of S and the large knitting position TL arranged between the storage position TG and the small knitting position TS, the dog 10 is detachable with the stop position as the large knitting position TL. Thus, even if the stop position of the reflector is different between the small knitting and the large knitting, not only can the dog 10 be provided at the intermediate large knitting position TL to stop the reflector to the large knitting position TL, but the dog 10 The movement of the reflecting plate to the small knitting position TS is also permitted by removing. Therefore, even when the reflector is positioned and stopped at the large knitting position TL, manual operation of the motor by the operator becomes unnecessary, and the work of visually stopping the reflector is eliminated.
<Second Embodiment>
The dogs 101 and 102 are attached to the base 5 as in the positioning device for the traveling body in the second embodiment shown in FIG. 9 and the positioning device for the traveling body in the modification of the second embodiment shown in FIG. The brackets 901 and 905 may be connected so as to be raised and lowered.

  In the positioning device shown in FIG. 9, the dog 101 is hinged to the bracket 901 attached to the base 5 so that the dog 101 can be raised and lowered with respect to the bracket 901.

  As shown in FIG. 9, the bracket 901 is fixed to the side surface of the flange 5 a in the base 5, and extends from above the fixing plate 902 in a direction horizontal to the flange 5 a and away from the rail 7. And a dog mounting plate 903.

  The dog 101 has a flat plate shape and has a slope above the back side of the stage S, and is connected to a dog mounting plate 903 of the bracket 901 by a hinge fitting 904. When the small reflecting plate 2 is stopped at the large knitting position TL, as shown by the solid line in FIG. 9, the switches 53 and 54 may detect the dog 101 with the dog 101 raised. Further, when it is not desired to stop the small reflector 2 at the large knitting position TL, as shown by a broken line in FIG. 9, the dogs 101 are turned down so that the switches 53 and 54 cannot detect the dog 101. Good.

  In the positioning apparatus shown in FIG. 10, the dog 102 is pin-coupled to a bracket 905 attached to the base 5 so that the dog 102 can be raised and lowered with respect to the bracket 905.

  As shown in FIG. 10, the bracket 905 is fixed to the side surface of the flange 5 a in the base 5, and extends from above the fixing plate 906 in a direction horizontal to the flange 5 a and away from the rail 7. And a dog attachment plate 907.

  The dog 102 has a flat plate shape and has an inclined surface above the back side of the stage S, and is connected to a dog mounting plate 907 of the bracket 905 by a pin 908. When the small reflecting plate 2 is stopped at the large knitting position TL, it is only necessary that the switches 53 and 54 can detect the dog 102 in a state where the dog 102 is raised as shown by a solid line in FIG. Further, when it is not desired to stop the small reflector 2 at the large knitting position TL, the switches 53 and 54 cannot detect the dog 102 with the dog 102 tilted downward as shown by the broken line in FIG. What should I do?

  Thus, even in the positioning device for the traveling body of the second embodiment, if the dogs 101 and 102 are raised, the small reflector 2 that is the traveling body can be automatically positioned and stopped at the stop position, If the dogs 101 and 102 are tilted, the passage of the small reflector 2 can be allowed.

  Therefore, according to this positioning device, a traveling body that needs to be positioned and stopped at a plurality of positions can be automatically positioned and stopped by selecting an arbitrary position among the plurality of positions as a stop position. In addition, since the dogs 101 and 102 are connected to the brackets 901 and 905 in an undulating manner, it is possible to easily select stopping and passing of the traveling body by the undulating operation of the dogs 101 and 102, and worry about the dogs 101 and 102 falling. Nor.

  For the purpose of the present invention, the traveling body is not limited to the small reflecting plate 2 of the acoustic reflecting plate RB, and can be used as a positioning device for the traveling body that is selected to stop and pass at the stop position.
