【Example】

 An embodiment of the present invention will be described below with respect to a structure for transferring the carriage 1. The first embodiment of FIG. 1 is a side view of a truck transfer device in which a chain 8 described below, which is a drive belt, is formed in a non-loop shape. It shows a structure in which the trolley 1 is transferred between and. 2 is a partially omitted plan view of the carriage transfer device of FIG. 1, and FIG. 3 is a view taken along the line III-III of FIG. The wheel 3 rolls on the left and right rails 5a and 5b (the left rail 5a is not shown in FIG. 1). The traction body 4 that engages with the wheels 3 and transfers them is guided to a ground-side guide portion E composed of a left-side rail 5a on the ground side and a guide rail 6 installed close to the left-side rail 5a. Then, on the chassis side, the chassis side guide part E connectable to the ground side guide part E can guide and move. In the illustrated example, two sets of traction bodies 4 are used to move the two trolleys 1 and 1 synchronously, and the traction bodies 4 and 4 arranged corresponding to the front and rear trolleys 1 and 4 are used. , And are connected by the connecting body 7. Even if only one tow body 4 is provided, it does not hinder the following configuration.

The front and rear end portions of a pair of left and right chains 8, 8 or a drive band composed of wires, belts and the like (not shown) are locked to the front and rear towing bodies 4 and 4 via tension mechanisms 9 and 9, respectively. are doing. A drive motor 12 and a drive sprocket for the drive motor 12 in which the drive belt 12 and the chain 8 are wound in a drive pit 11 provided separately from the traverse pit 10 of the traverser 2. A drive unit M including 13 (a drive pulley for a wire and a belt) and guide sprockets 14 and 15 (a guide pulley for a wire and a belt) is housed and installed. Hereinafter, in FIG. 1, FIG. 2, FIG. 4, and FIG. 5, the left side will be described as the front side, and the right side will be described as the rear side.

FIG. 5 is an example of the towing body 4 and is a plan view in which the central portion is omitted. As shown in FIG. 5, the tow body 4 has four guide rollers that ride on the I-shaped inner bottom portions 16 and 17 of the rail 5a and the guide rail 6 that are the ground side guide portion E or the chassis side guide portion W. 18 and four guide rollers 21 which roll in contact with the I-shaped standing portions 19 and 20 of the rails 5a and the guide rails 6 which are the guide portions E and W, and during transfer movement. Is urged counterclockwise of the fulcrum pin by a spring (not shown) as shown in FIG. 4, and is held upright at a position where it abuts against a stopper (not shown), and the fulcrum pin is supported by a spring (not shown). It is urged clockwise and engages the wheel 3 from the rear, and is held upright at a position where it abuts a stopper (not shown), but is pushed down by the rolling of the wheel 3 in the transfer direction (from the rear). Rear side formed to retreat outside the rolling trajectory B - a la -23, front Russia - The La -22A, pushed to the same axis B - are provided la -22B.

In FIG. 1, the front traction body 4 and the connecting body 7 are projected to the maximum forward from the traverse sapit 10, and the rear roller 23 is still engaged with the wheels 3, but -It is a substantially complete transfer position of the trolley 1 to the service 2. In FIG. 4, the rear traction body 4 and the connecting body 7 are projected rearward from the traverse sapit 10 to the maximum, and the traction body 4, the connecting body 7 and the chain 8 evacuate outside the movement trajectory of the traverser 2. The engagement complete position (transfer start position) of the rollers 22a and 23 with respect to the new wheel 3 is shown. When the towed body 4 starts to move forward from the position shown in FIG. 4 and reaches just before the position shown in FIG. 1, that is, at the end of the movement in the transfer direction, the engaging member of the guide mechanism (not shown) is engaged. The push-in roller 22b collides with it so that the front-side roller 22a falls down and retracts from the rolling locus of the vehicle wheel 3, and the towing body 4 moves backward from the position shown in FIG. 4 until the position immediately before the position of FIG. 4 is reached, that is, until the end of the backward movement for engaging the rollers 22a and 23 with the wheel 3 on the rear side of the new carriage 1 is completed. The front guide roller 22a is held in a lying state by the latch of the guide mechanism, and when the position shown in FIG. 4 is reached, the arm 22c of the front roller 22a is removed from the latch by the guide mechanism. The structure is such that the roller 22a rises when it is disengaged.

As a result, when the trolley 1 arrives just before the transfer completion position on the traverser 2, the front roller 22a falls down, so that the trolley 1 moves further forward (or the trolley 1 On the other hand, when the towed body 4 retreats), the rear wheel 3 can relatively pass over the laid-down front roller 22a. Further, at the end of the backward movement of the towing body 4 for engaging the wheel 3 of the new truck 1, the front wheel 3 of the truck 1 that is stationary depresses the rear roller 23 and falls down. The front side roller 22a, which is relatively close to the front side, and when the rear side wheel 3 finishes passing over the front side roller 22a, the arm 22b is disengaged from the latch. The roller 22a is erected and engaged with the wheel 3 on the rear side from the front side. At this time, the drive unit motor 12 is stopped and the backward movement is controlled so that the rearward movement is completed. Is engaged with the wheel 3 on the rear side from the rear while still standing up to the engagement completion position shown in FIG.

An example of the tension mechanism 9 of the chain 8 is shown in FIG. 5 which is a plan view of a main part and FIG. 6 is a view taken along the line VI-VI in FIG. The tension mechanism 9 includes a rod 24 connected to the rear end of the chain 8 (located below the towing body 4), a collar 25 and a guide plate 26 that are loosely fitted to the rod 24, and a collar 27. (A nut 28 screwed to the rear end of the rod 24 prevents the rear end from coming off), and an end rod 29 of the traction body has mounting rods 30 and 31 (also serving as guides for a spring 32 described later). A pair of left and right guide bridges 34 fixed by way of guide rods 33, 33 described below and a bridge between the tow body end 29 and the guide rod mount plate 34 so that the guide plate 26 can slide. The guide rods 33, 33 and the spring 32 interposed between the end portion 29 of the traction body and the guide plate 26. Therefore, when the chain 8 is driven forward in FIGS. 1 and 5, the tow body 4, the collar 27, the guide plate 26, and the collar 25 are integrated as shown in FIGS. The rear end of the −25 and the guide plate 26, and the front end of the collar 25 and the end 29 of the towing body all come into contact with each other, and the driving force by the chain 8 is passed through the collar 25 and the end 29 of the towing body 4 to draw the drafting body 4. Is transmitted to and the towing body 4 is moved forward. On the other hand, when the chain 8 is driven rearward in FIGS. 1 and 5, the rear side of the driving sprocket 13 is on the loose side, and the looseness of the chain 8 generated on the loose side is caused by the spring 32. Although not shown in the figure due to the extension, a gap is formed between the guide plate 26 and the collar 25, so that the guide plate 26 and the color 25 are absorbed.

In the traverser 2 illustrated in FIG. 1, the wheels 36, 36 are guided by the traverse rails 35, 35 perpendicular to the ground side guide portion E and the chassis side guide portion W, and the direction orthogonal to the paper surface. It is a structure that moves to.

Next, the operation when the truck 1 is transferred from the ground side to the traverser 2 will be described. The new carriage 1 is stationary at the position shown in FIG. 4, and the towing body 4 is moved backward from the drive pit 11 by the drive motor 12 from the vicinity of the position shown in FIG. 4 is the end of the backward movement of the towing body 4 before the engagement completion position, and the front wheel 3 of the carriage 1 depresses the rear roller 23 to become the engagement member of the guide mechanism. It relatively passes over the front roller 22a which is more prone, and when the rear wheel 3 finishes passing over this roller 22a, it disengages from the latch and the front roll 22a. The roller 22a stands up and engages with the wheels 3 on the rear side from the front. At this time, the drive unit motor 12 is stopped and controlled by a command from a control circuit (not shown), and the rear roller 23 stands up. As it is, the wheel 3 on the rear side is engaged from the rear to reach the engagement completed position shown in FIG. Thus, at the end of the backward movement of the towing body 4, the rear roller 23 is stepped down by the relative transfer direction rolling of the wheel 3 with respect to the towing body 4, and no manual operation is required. When the vehicle retreats out of the rolling locus and finishes the backward movement, the front roller 22a is from the front of the wheel 3 and the rear roller 23 is from the rear of the wheel 3 and is not artificial. Since the engagement is performed without any operation, the engagement operation of the wheels 3 of the new carriage 1 is simple.

Next, the drive unit motor 12 is driven clockwise, and the chain 8 moves forward via the drive sprocket 13 and the guide sprockets 14 and 15. The front and rear rollers 22a and rollers 23 standing upright and engaged with the wheels 3 are moved by the wheels 3 when the brakes are being conveyed or when the brakes are used to stop the towing bodies 4. To prevent you from rolling from front to rear. The guide roller 18 of the towing body 4 is located at the inner bottom portions 16 and 17 of the rail 5a and the guide rail 6, and the guide roller 21 is located at the standing portions 19 and 20 of the rail 5a and the guide rail 6. Each of them is guided, and thus the towing body 4 is guided to the ground side guide portion E on the ground side, and when it enters the traverser 2, it is guided to the chassis side guide portion W and moves smoothly. The wheel 3 is pushed forward by the roller 23 of the towing body 4 to roll forward on the rails 5a and 5b, and the carriage 1 is transported forward.

At the end of the movement in the transfer direction when the towed body 4 arrives just before the position in FIG. 1, the front roller 22a is laid down by the engagement member of the guide mechanism and the wheels 3 roll. The vehicle retreats from the locus and the clockwise rotation of the drive unit motor 12 is stopped by a command from the control circuit to reach the transfer completion position on the traverser 2 shown in FIG. It is located above the drive unit M. Therefore, when the drive unit motor 12 is driven counterclockwise to move the towing body 4 backward, the rear wheel 3 relatively passes over the lying front roller 22a, and the trolley 1 moves. Left on the traverser 2, the guide rollers 18 and 21 are guided from the chassis side guide portion W to the ground side guide portion E, and the towing body 4 moves from the traverser 2 to the ground side. Thus, from the end of the movement of the towed body 4 in the transfer direction to the end of the backward movement for engaging new wheels, the front roller 22a is retracted outside the rolling locus of the wheels 3. Therefore, when the towed body 4 is retracted after the movement in the transfer direction to the predetermined position on the moving chassis or the ground side is completed, some manual operation is required to retract the front roller 22a. Instead, the towed body 4 can be moved backward, and the transfer operation is simple. Since the tow body 4, the connecting body 7 and the chain 8 are again retracted outside the movement trajectory of the traverser 2, the traverser 2 follows the truck 1 along the traverser rails 35, 35 and the rail. It can move in a direction orthogonal to 5a and 5b. When the tow body 4 moves backward, the chain 8 on the front side in the moving direction becomes a slack side, and a gap is created between the guide plate 26 and the collar 25 of the tow body 4 on the front side. The slack of 8 is absorbed.

In the above-described first embodiment, the ground side guide portion E, the towing body 4 provided with the roller 23 that engages with the wheels 3, the chain 8 to be locked by the towing body 4, the drive band of the wire and the like. The body and the drive unit M are provided on the ground side, and the positions of the drive belt 8, the towing body 4, and the drive unit M can be saved outside the movement locus of the traverser 2 that is the moving chassis or outside the movement locus. Therefore, the transfer equipment such as the towing body 4 and the drive belt 8 is provided for the vehicle chassis such as the chassis rail, pit, and chassis drive mechanism provided below the vehicle chassis 2. Therefore, it is suitable as a trolley transfer device for a mobile trolley.

In addition, in the first embodiment, the chain 8 is not in a loop shape, so that the part on the return side when the endless chain is used is unnecessary, and the space required for driving the chain 8 is unnecessary. As is clear from FIG. 1, the space is small and a simple drive structure could be obtained. Since the drive sprocket 13 is arranged at a position lower than the pulling surface of the chain 8, the drive section pit 11 is sufficient to accommodate the drive section M such as the drive sprocket 13 and the drive motor 12. A narrow space is sufficient, and a deep and long drive unit pit for accommodating the entire chain including the return side portion such as a loop-shaped chain is unnecessary.

According to the tension mechanism 9 of the chain 8 shown in FIG. 5, the chain 8 and the tow body 4 are connected by the collar 25, which is a space holding member, on the rear side in the tow direction, and the spring 32 has a large tow force. Does not act, the spring 32 does not become tired or buckle, and the looseness of the chain 8 is absorbed by the spring 32 on the front side in the pulling direction to prevent the chain 8 from coming off from the drive sprocket 13 and the guide sprockets 14 and 15. There are features that can be prevented.

In the second embodiment of the transfer device shown in a side view (the left rail 5a is not shown) in FIG. 7, the chain 37, which is a drive band, is hung on the sprockets 38, 39. It is turned into a loop shape, and a chain 37 is arranged in a drive unit pit 40 provided at the rear of the traverse sapit 10. The same members as those in the first embodiment shown in FIG. 1 are designated by the same reference numerals and their structural description is omitted. When the connecting body 7 is locked to the chain 37 by the connecting metal fitting 41 and the connecting metal fitting 41 is retracted from the position shown in FIG. 7 to the vicinity of the rear sprocket 39, although the illustration is omitted, the towing body 4 is moved to the traverse. -It is set to evacuate outside the movement path of the service 2. In this second embodiment, since the loop-shaped chain 37 is used as the drive belt, the drive structure of the drive portion M of the chain 37 causes the rotation of the drive motor 12 to rotate with the sprockets 42 and 43 and the chain 44. Is transmitted to the sprocket 39 by means of a simple and commonly used one.

In the third embodiment of the transfer device shown in the side view in FIG. 8, the traction body 4, the non-looped chain 8, which is the drive belt, and the traction body 4, which are on the side of the rolling stock 45 which is the moving chassis. The drive unit M is provided so that the towing body 4 and the like can turn together with the turntable 45. The same members as those in the first embodiment shown in FIG. 1 are designated by the same reference numerals, and the structural description thereof is omitted. The single tow body 4 is longer than that in FIG. 1, and the chain 8 is formed to be short, and the tension mechanism 9, the drive unit M and the like are the same as those in FIG. The drive unit M installed at the lower part is housed in the turntable pit 46. The illustrated turntable 45 is turned around by a wheel 49, 49 rotating on a circular turntable rail 48 centered on a rotation center 47 of the turntable 47. The rails 5a, 5b of the chassis side guide portion W are connected to the illustrated rails 50a, 50b.

9 and 11 show the transfer completion position of the tow body 4 on the turntable 45 because the tow body 4 is located right above the turntable 45, and FIG. This is a substantially complete transfer position to the chassis 45. 8 and 10, the towing body 4 is projected rearward from the turntable pit 46 to the maximum. FIG. 8 shows the front wheel 3 of the new truck 1 and FIG. 10 shows the rear wheel 3 thereof. Is the engagement completion position (the transfer movement start position) where the rollers 22a and 23 are engaged. When the towed body 4 starts to move forward from the position shown in FIGS. 8 and 10 and reaches immediately before the position shown in FIGS. 9 and 11, that is, at the end of the movement in the transfer direction, the guide mechanism not shown is shown. The pushing roller 22b collides with the engaging member of FIG. 2 to cause the front roller 22a to fall down and retract from the rolling locus of the wheel 3, and from the positions shown in FIGS. Until the towed body 4 starts to move backward and reaches the position immediately before the position shown in FIGS. 8 and 10, that is, the front wheel 3 or the rear wheel 3 of the new carriage 1 is provided with the rollers 22a ,. Until the end of the backward movement for engaging 23, the front roller 22a is held in a sunk state by the latch of the guide mechanism (not shown), and when it reaches the position shown in FIGS. As a result, the arm 22b of the front roller 22a is removed from the latch. Te Russia - has a structure to be erected La -22a.

Next, an operation when the carriage 1 is transferred from the ground side to the turntable 45 will be described. When the towed body 4 is moved backward with respect to the new carriage 1 that is stationary just behind the turntable pit 46, the wheels 3 on the front side of the carriage 1 immediately before the engagement completion position shown in FIG. -When the front wheel 3 finishes passing through the rear roller 23 by depressing the roller 23, the front roller 22a which has been laid down by the engaging member of the guide mechanism is Standing up off the latch. When the trailer roller 23, which has been stepped down, stands up, the drive unit motor 12 is stopped and controlled by a command from a control circuit (not shown), and the front roller is moved. The wheel 22a engages with the wheel 3 on the front side from the front while the roller 23 on the rear side and the roller 23 on the rear side stand up to the engagement completion position in FIG. Next, the drive unit motor 12 is driven clockwise to move the traction body 4 forward, and the guide mechanism is engaged at the end of the transfer direction movement in which the traction body 4 reaches immediately before the position of FIG. The front roller 22a is laid down by the member and retracts from the rolling locus of the front wheel 3, and the clockwise rotation of the drive unit motor 12 is stopped by the command of the control circuit and the rotation shown in FIG. The transfer completion position of the towing body 4 to the chassis 45 is reached, and only the front wheels 3 of the carriage 1 are transferred to the transfer platform 45. Then, when the drive unit motor 12 is driven counterclockwise, the towed body 4 moves backward and the front wheels 3 pass over the lying front roller 22a, and then the rear wheels. When the rear wheel 23 is stepped down by the rear wheel 3 and the towed body 4 is further moved backward and the rear roller 23, which has been stepped down, stands up, the drive unit motor 12 is turned on. Stopping is controlled by a command from a control circuit not shown, and immediately before this, the front side roller 22a disengages from the latch and stands up from the front side, and the rear side roller 23 stands upside down from the rear side. The wheel 3 is engaged to reach the engagement completion position shown in FIG. The trolley 1 is left on the rolling trolley 45 in the position shown in FIG.

Again, the drive unit motor 12 is driven in the clockwise direction to move the towing body 4 forward, and at the end of the transfer direction movement in which the towing body 4 reaches immediately before the position of FIG. 11, the front roller 22a falls down and retracts from the rolling locus of the rear wheel 3, and the drive circuit motor 12 is stopped from rotating clockwise according to a command from the control circuit. At the transfer completion position of the trolley 1 on the trolley stand 45, the front and rear wheels 3 and 3 are both transferred to the trolley stand 45. Then, when the rolling-bed driving motor is driven, the wheels 49, 49 rotate on the rolling-rail rail 48 and the rolling-bed 45 turns, and the rails 50a, 50b are guided to the rolling guides W of the rolling-bed-side guide portion W. -Rules 5a and 5b are connected.

According to the third embodiment, since the transfer equipment for the towing body 4, the chain 8, and the drive unit M is provided on the transfer stand 45 which is the moving stand, these are provided on the ground side. As such, there is no need to provide a transfer facility for each transfer destination. Further, the third embodiment is useful when the transfer equipment such as the towing body 4 and the chain 8 cannot be arranged on the ground side because the front and rear of the turntable 45 are narrow, for example.

When the bogie 1 is transferred back and forth from the turntable 45 to the rails 5a and 5b, the towing body 4 (which faces the direction shown in FIG. 1) as in the first embodiment shown in FIG.

[Effect of device]

 As described above, according to the present invention, the ground-side guide portion, the towing body including the rollers that engage with the wheels, the chain that is locked to the towing body, the drive belt body such as the wire, and the drive portion are provided. It is installed on the ground side and the positions of the drive belt, the traction body, and the drive unit are set so that they can be saved outside the movement locus of the moving chassis or outside the movement locus. The transfer equipment does not interfere with the equipment for moving carriages such as the chassis rails, pits, and chassis drive mechanism provided below the moving carriage, and is suitable as a moving equipment for moving carriages. Is.

Since the towing body provided with the rollers engaging with the wheels, the chain to be locked to the towing body, the drive belt body such as the wire, and the transfer equipment for the drive unit are provided in the moving chassis. Unlike the structure where these are installed on the ground side, there is no need to provide transfer equipment for each parallel movement destination by the traverser and each turning destination by the turntable.

By forming the driving strip in the shape of a loop, the driving structure of the driving strip becomes a simple structure which is normally used.

By forming the drive strip in a non-loop shape, a space for the drive strip on the return side, such as a loop shape, becomes unnecessary.

The front roller, which is provided so as to be engaged with the wheel from the front in the transfer direction, cooperates with the rear roller to allow the wheel being transferred to move freely on the tow body. Prevent rolling. The front roller is retracted out of the rolling locus of the wheel from the end of the transfer direction movement of the traction body to the end of the retraction movement of the traction body for new wheel engagement. Since it is configured, when the moving direction to the predetermined position on the moving chassis or the ground side is completed, the trolley is moved to the above predetermined position without requiring any manual operation for retracting the front roller. The towed body is moved backward, leaving the transfer operation completed. Moreover, the rear roller is formed so as to be retracted from the rolling locus by rolling of the wheel in the transfer direction, so at the end of the backward movement for engaging the wheel of the new truck. When the trolley moves relative to the towing body in the transfer direction, it is stepped out of the rolling locus by the wheel and evacuates, and the wheel passes over the rear roller and finishes the backward movement. When standing up, the front and rear rollers are engaged with the wheels from the front and rear. The operation of these front and rear rollers does not require any manual operation and is performed in a timely manner.

At the position where the chassis side guide part and the ground side guide part are connected, the positioning member that is inserted and fitted into the chassis side guide part or the ground side guide part when the drive belt is driven Since it is provided at the tip, it becomes easy to align the position when the moving chassis is turned or translated.
