DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a so-called power-and-free type transporting pusher for a transporting body, which is propelled by a pusher on a drive chain side.

(Prior Art) The so-called power-and-free transfer vehicle as described above is, as is well known in the art, a main dog that can move up and down on a leading trolley, and can fall forward and downward behind the dog. A leading prevention dog that is lower than the dog, and a stop operated tool that can swing up and down in conjunction with the main dog and that extends forward are provided, and the trailing end trolley is lower than the leading prevention dog. It is provided with a back-up dog and an operating tool for operating the operation target article for stopping in the succeeding transporting moving body, and a normal power line equipped with a drive chain with pushers is provided side by side. In the transport path, the pusher on the drive chain side is fitted between the main dog and the leading prevention dog of the leading trolley, and the pusher pushes the main dog to push it forward. .

The transfer vehicle as described above, a path not provided with a power line including the drive chain with pusher,
For example, when moving the transporting mobile unit in an elevating path for elevating and lowering for unloading or moving to another path of a different level, a booster is required. That is,
Using the pusher that engages with the main dog of the leading trolley, the transporting movable body pushed to the position where the leading trolley enters the lifting route is completely drawn into the lifting route, and then the trailing end trolley A pushing device that pushes the transporting moving body out of the ascending / descending path by using the pusher that engages with the pushing dog is required.

A conventional booster of this type is, for example, Japanese Utility Model Publication No. 57-42756.
A push chain equipped with a leading end trolley and a pusher for pushing out the rear end trolley at a predetermined distance from each other in a drive chain stretched in an endless manner like the pusher equipped with a drop lifter disclosed in Japanese Patent Publication No. In order to prevent the leading trolley retractor pusher from colliding with any part other than the main dog, when both pushers are the same as described in the above publication, there are a high level section and a low level section in the boosting route. When setting and moving both pushers at the same level, the length (height) of both pushers was made different.

(Problems to be Solved by the Invention) In the conventional booster device as described above, the number of parts is large,
It became a large-scale device with a complicated structure, and it was unavoidable that the cost was greatly increased by installing this type of booster device.

(Means for Solving the Problems) In order to solve the above conventional problems, the present invention provides
A movable body capable of reciprocating in parallel to the rearward pushing path and a driving means for the movable body are provided on the rearward pushing path of the trolley-type transporting movable body as described above, and the movable body is capable of vertically swinging rearward pushing. A pusher for use is provided, and a first pusher portion extending forward at a height capable of contacting only the main dog of the leading trolley and a tip of the first pusher portion abuts the main dog. When the rear trolley is not in contact with other parts of the leading trolley, the rear trolley has a second rear pushing portion that can only come into contact with the rear pushing dog. It is a proposal.

(Embodiment) An embodiment of the present invention will be described below with reference to the attached exemplary drawings.

In FIG. 1 to FIG. 3, 1 is a moving body for transportation,
Main body 4 suspended by a pair of front and rear trolleys 2, 3.
And a front trolley 5 connected to the front trolley 2 via a connecting rod 5a, and an appropriate hanger (not shown) for suspending the transported object is attached to the main body 4.

As shown in FIG. 4, the leading trolley 5 is supported by a main dog 8 which is supported so as to be able to move up and down between the elevating guide rollers 6 and 7, and is laid down forward and downward by a support shaft 9 behind the dog 8. A forward prevention dog 10 that is rotatably supported and lower than the dog 8, and a lower end of the main dog 8 that is interlockingly connected through a connecting pin 11 and that is pivotally supported by a support shaft 12 so as to be vertically swingable. There is provided a stop operated tool 13 extending to. However, the stop operated tool 13 also serves as a weight as an urging means for raising the main dog 8. Reference numeral 14 is a horizontal axis wheel for support, and 15 is a vertical axis roller for steady rest.

As shown in FIG. 5, the rear end trolley 3 has a rear pushing dog 16 lower than the preceding prevention dog 10 and a stopping operated tool 13 in the succeeding moving body 1 for moving upward. A cam-like operation tool 17 is provided so as to extend rearward so as to allow the operation. 18 is a horizontal axis wheel for support, and 19 is a vertical axis roller for steady rest. As shown in FIG. 1 and the like, the trolley 2 is also supported by a supporting horizontal shaft wheel 20 and a steady rest vertical shaft roller 21.

Each of the trolleys 2, 3, 5 has a respective supporting horizontal axis wheel 1
Guide rails 22 and lifting guide rails 23 via 4,18,20
Although not shown in the drawing, the pusher of the drive chain moving along the guide rail 22 is movably supported by the main dog 8 of the leading trolley 5 and the preceding prevention. It engages with the dog 10 and is pulled by the pusher to run.

Reference numeral 24 denotes a pusher device that moves up and down integrally with the elevating guide rail 23, and includes a rodless cylinder unit 26 mounted in parallel with the elevating guide rail 23 on a support frame 25 installed above the elevating guide rail 23. The push-pusher 30 pivotally attached to the reciprocating movable body 27 of the rodless cylinder unit 26 so as to be vertically swingable within a certain range via the bearing bracket 28 and the horizontal horizontal shaft 29, and the reciprocating movable body 27. When it is at the start end of the reciprocating movement path, the pusher lifting operation piece 31 that moves the pusher 30 upward and retracts.
It has and.

The rear pushing pusher 30 has a first rear pushing portion 32 extending forward at a height capable of contacting only the main dog 8 of the leading trolley 5, and a tip end of the first rear pushing portion 32 is the main dog 8. A second rear pushing portion 33 which is in a position not contacting the other portion of the leading trolley 5 when it is in contact with the rear trolley 3 and is capable of contacting only the rear pushing dog 16 of the rear trolley 3. . Incidentally, 34 is the pusher which moves downward due to gravity.
A stopper for holding 30 in the working posture, which abuts on the rear side surface of the bearing bracket 28.

Further, as shown in FIGS. 1 and 2, in the vicinity of the exit of the elevating guide rail 23, there is disposed a conventionally known leading trolley stopper 35 which is movable in the horizontal lateral direction.

As shown in FIG. 1, the reciprocating movable body of the cylinder unit 26.
When 27 is at the beginning of the reciprocating path, the pusher
30 is lifted by a pusher lifting operation piece 31 and is held at a height that does not collide with any part of the transporting movable body 1. In such a state, the transporting mobile body 1 traveling forward along the guide rails 22 is
When the leading trolley 5 that has moved up is stopped at a position reaching a position slightly forward of the position directly below the pusher 30, the reciprocating movable body 27 of the cylinder unit 26 is driven to move the pusher 30 forward. As a result, the pusher 30 moves down from the pusher lifting operation piece 31 to the working posture, and then, as shown in FIG. 4, the pusher 30 comes to the rear side of the upper end of the main dog 8 in the stopped leading trolley 5. Since the tip of the first rearward pushing portion 32 comes into contact with and pushes the main dog 8 backward, the pusher 30 moves the transporting movable body 1 through the leading trolley 5 through the leading trolley 5 as shown by the phantom line in FIG. Will pull up.

As shown in FIG. 2, when the reciprocating movable body 27 reaches the end position of the reciprocating movement path and the pusher 30 stops, the conveying moving body 1 travels on the elevating guide rail 23 by inertia, and the leading trolley stopper. It stops at a position where the leading prevention dog 10 of the leading trolley 5 comes into contact with 35. At this time, the main dog 8 is in a state of being pushed down by the stopper 35. Further, the rear end trolley 3 of the transporting movable body 1 reaches a position which is sufficiently distant in the forward direction side of the reciprocating movable body 27 from the position directly below the starting end portion of the reciprocating moving path of the reciprocating movable body 27 shown in FIG. ing. On the other hand, the reciprocating movable body 27, which has stopped at the end of the reciprocating path as described above, is immediately driven in the opposite direction to move the pusher 30 backward to the original starting end as shown by the phantom line in FIG. It should be noted that, at the time of this backward movement, the pusher 30 passes over the rear pushing trolley 3 of the rear end trolley 3 of the transporting movable body 1 which has stopped on the lifting guide rail 23 as described above. When this is done, the second pushing portion 33 collides with the pushing dog 16 and the horizontal horizontal axis 29
Will swing up around.

When the transporting movable body 1 is completely pulled in on the lift guide rails 23 as described above, the elevator guide rails 23 are moved up and down, and, for example, loading and unloading work for the transporting movable body 1 is performed. After the work is completed, the elevating guide rail 23 is moved up and down to the original height again, and the guide rail 22 and the elevating guide rail 23 are connected. After that, when the front trolley stopper 35 is retracted and the reciprocating movable body 27 of the cylinder unit 26 is driven in the forward direction again, the second push of the pusher 30 separated from the pusher lifting operation piece 31 to the working posture is performed. The transportation unit 1 in which the section 33 is stopped
Abutting the dog 16 for pushing on the rear trolley 3
Since the pusher 30 pushes the back pushing dog 16, the transporting moving body 1 is pushed out from the upper and lower guide rails 23 as shown in FIG. However, when the reciprocating movable body 27 reaches the end portion of the reciprocating movement path, the leading trolley 5 of the transporting moving body 1 pushed out from the up-and-down guide rail 23 is attached to the guide rail 22 to which the transfer is made. Drive means (drive chain with pusher)
Has reached a position where the pusher and the main dog 8 can be engaged with each other, and thereafter, the pusher of the drive means continues to drive the entire moving body 1 for conveyance up and down the guide rail.
You will have to transfer from 23 to above the guide rail 22.

Incidentally, when the pusher 30 is at the starting end position of the reciprocating movement path of the reciprocating movable body 27, the pusher 30 is lifted so that the pusher 30 does not come into contact with any part of the transporting moving body 1. However, since the pusher 30 is of a so-called anti-back type, the pusher 30 does not need to be lifted as described above by the main dog 8 and the leading prevention dog 10 of the leading trolley 5 when the transporting vehicle 1 enters. It only temporarily swings upward, and does not hinder the entrance of the transporting mobile unit 1.

(Operation and effect of device) As described above, according to the booster device for a transporting vehicle of the present invention, the pusher for pushing is made to stand by at the start end portion of the boosting route of the transporting vehicle for transporting, and After the transporting moving body is moved forward so that the leading trolley is positioned, the pusher is moved forward to push the main dog of the leading trolley backward with the first pushing portion of the pusher, and thus The moving body can be retracted to a predetermined position in the back-pushing path. After this pulling-in is completed, the pusher is moved backward to the original starting end portion. A retracting distance of the moving body, that is, a reciprocating moving distance of the movable body having the pusher is set.

However, by moving the pusher forward, the second pushing portion of the pusher pushes the trailing dog of the trailing end trolley, thereby pushing the transporting movable body out of the pushing path.

In this way, by merely moving one pusher back and forth by the driving means, the transporting movable body is moved to a predetermined position by using the main dog and the rear pushing dog, which are generally provided in the leading trolley and the trailing trolley. It can be pulled in and pushed out. Therefore, compared to the conventional booster that requires two pushers to be circulated,
The number of parts is small, the structure is extremely simple, and it can be implemented at low cost.
