DETAILED DESCRIPTION OF THE INVENTION According to the present invention, a roller that comes into contact with a drive shaft supported along a transport vehicle moving path is pivotally supported on a transport vehicle, and the roller is mounted so that its axis is oblique to the axis of the drive shaft. The present invention relates to a conveyance device using a conveyance vehicle, in which the conveyance vehicle is propelled by taking an intersecting posture, and the conveyance vehicle is selectively moved to a stop position set in the movement route with high positional precision. This is to enable automatic stop when the width is wide.

An embodiment of the present invention will be explained below with reference to the attached illustrative drawings. Reference numeral 1 denotes a transport vehicle, which has horizontal shaft rollers 4 at four corners that ride on a pair of left and right guide rails 2. It is equipped in two places, front and rear.

Reference numeral 6 designates a chain conveyor installed in the transverse direction of the transport vehicle 1F-, and is driven by the motor 7 of the transport vehicle 11-.
The object to be transported is transported via the transport platform (pallet, etc.) 8.
The receiver is transferred between the conveyor l- installed on the floor 1-.

9 is the floor surface E at the center position between the guide rails 2 and 6.
The drive shaft is supported parallel to the guide rail 2.5. 10 horizontal shaft rollers press against the drive shaft 9 from the L direction, and a support frame 11 that pivotally supports the rollers 10 is rotatably supported on the bottom of the transport vehicle 1 around a vertical shaft 12. Sleeping. 13 + 2' (a moving cam rail, the outer end is supported by a vertical shaft 1415 at the front and rear of the bottom of the transport vehicle 1, and the inner end of the inner end is stacked q. This is connected by a vertical shaft 17.1!-1, which is connected by a vertical shaft 17.1!-1, which is composed of a cam rail member 18 and a cam rail member 19 for reverse movement. - A stone pin 21 that loosely fits into an elongated hole 20 provided in the rail member 19 is provided protruding from the transport vehicle 1 to prevent it from rotating outward beyond the limit position a shown in FIG. It is configured as follows. In order to prevent the inner ends of both cam rail members 18 and 19 from sagging, the transport vehicle 1 is provided with a trolley that can move in left and right transverse directions, and this trolley moves the inner ends of the cam rail members through the vertical shaft 17. It can be configured so that it can be hung. In this case, the trolley's f! By limiting the length of the 8-movement path, the stopper pin 21 can be omitted.

A cam driven roller 22 is pivotally supported by a vertical shaft on the support frame 11 of the roller 10 at a position away from the vertical shaft 12, and the support frame 11 is pulled in the direction in which the roller 22 comes into contact with the back surface of the cam rail member 19. As a result, when the movable cam rail 1'5 is at the extension limit position a as shown in FIG. It is configured to assume a driven position tilting at an angle of 45 degrees with respect to the vehicle.

Reference numeral 24 denotes a reverse check stopper provided at the bottom of the transport vehicle 1, which is connected to a pair of front and rear check pieces 28.29, which are pivoted on vertical shafts 25.26 and held at the stop position by tension coil springs 27. It is composed of Konera Gyakuyama Piece 28.29,
It is arranged one step higher than the movable cam rail 13.

Reference numeral 50 denotes a means for stopping the carriage provided at position A in relation to the carriage, and a lever pivotally supported by a vertical shaft 51! A roller 54 is pivotally connected to the tip of the cam rail 12 by a vertical shaft 55, and an action body rW that acts on the i1i'l cam rail 15 via a lever 55 that interlocks with the lever 52.
c, and a switching means (cylinder unit, etc.) 56 for switching to a retracted position 11d that does not act on the movable cam rail 15, and the lower half of the roller 34 constitutes an imitation tool 34a that acts on the movable cam rail 15 [7 , E
Subject 1F, half of whose weight is on the inverted 1st stopper 24
It constitutes the tool 34b. In addition, by changing the height of the lever 52, it is also possible to pivotally support the shared operation roller and the 1st togawa roller under the L of this lever 52. It is also possible to pivotally support the rollers on separate levers 1 that interlock with each other. Of course, you can also use a slider that moves in a straight line instead of a lever.

Next, to explain how to use and how it works, as shown in FIG. 1, when the roller 10 of the transport vehicle 1 is held in the driven position by the tension coil spring 2S, the drive shaft 9 is moved in the direction of the arrow 37. When rotated, a thrust in the direction of arrow 58, that is, in the forward direction, acts on the carrier 1 via the rollers 10, and the carrier 1 moves forward as the rollers 10 rotate. When the carriage 1 is to pass through the stop position IfA, the roller 54 of the carriage stopping means 50 at the stop position A is set to the retracted position lid where it does not act on the movable power rail 15. Transport vehicle 1 is stopped at position A
When the roller 54 is stopped, the operating tool 54a
Then, the locked tool 54b is switched to the operating position C. As a result, the movable cam rail 15 of the transport vehicle 1 moving forward
The lower half of the roller 54 C44 & tool on the cam rail member 18 while moving forward in ! +4a) comes into contact with the cam rail member 18 and presses the cam rail member 18 inward as the transport vehicle 1 moves forward.

Therefore, the reverse cam rail member 19 also swings inward, so that the roller 10 is moved to the first position against the tension coil spring 25 via the cam driven roller 22 and the support frame 11.
A transport vehicle 1 which rotates in the direction of an arrow 59 indicated by a dotted line in the figure. When the cam rail member 18.1 reaches the stop position A, the roller 54 moves toward the cam rail member 18.1 as shown in FIG.
9 and these cam rail members 18, 19
has been switched from the maximum extension position a (FIG. 1) to the backward eye position wIe, and the roller 10 has been switched to an idle rotation position f in which its axial center is parallel to the axial center of the drive shaft 9. Therefore, even if the drive shaft 9 is rotating in the direction of the arrow 57, the roller 10 only rotates freely, and no thrust is applied to the transport vehicle 1 in either the forward or backward directions, and the transport vehicle 1 is stopped. On the other hand, when the upper half of the roller S4, i.e., the locked tool 34b, the transport vehicle 1 reaches the stop position WtA, the non-return stopper 24 -.
On the other hand, the reverse one piece 28°t1. It is pushed away against the ridges 2 and '7 and is fitted into both the front and rear check pieces 28 and 29, so that the carrier 1 is accurately fixed at the stop position flA. In such a state, on the chess conveyor 6 of the transport vehicle 1,
Transfer work is performed between the conveyor and the fixed conveyor connected thereto.

When the transport vehicle 1 is started, the switching means 56 moves the roller 54 to the retracted position d, and the locked tool 54 is moved to the retracted position d.
b is a pair of non-return pieces 2B, 29 in front of the non-return stopper 24.
By moving the operating tool 54a from the movable cam rail 1!1 to the side, both the front and rear cam rail members 18, 19 of the movable cam rail 1S are moved through the roller support frame 11 and the cam driven roller 22. Then, the roller 10 swings outward under the force of the tension coil spring 25 and returns to the limit position a, and the roller 10 returns from the idle rotation position 1 to the driven position 1b. Therefore, the transport vehicle 1 receives thrust again and moves forward.

By rotating the drive shaft 9 in the opposite direction, one transport vehicle receives thrust in the opposite direction and moves backward. In this case, the lower half of the roller 54, ie, the operating tool 5.4a, acts on the backward cam rail member 19 to switch the roller 10 to the idle rotation position f, and the upper half of the roller S4, ie, the locked tool 54b is
Push aside the check piece 29 and fit between the check pieces 28 and 29.

The device of the present invention can be implemented and used as in the above-mentioned embodiments, and allows the carriage to be automatically brought out at a specific stop position without stopping the drive shaft 9, regardless of whether it is moving forward or backward. Not only can this be done, but the carrier can also be
Due to the automatic fitting between the stopper 24 and the stopper 24, it is possible to accurately fix the stop F at a predetermined top position.
can be automatically performed in conjunction with the movement of the operating tool S4a to return to the driven posture bK, and no special means for moving the locked tool 54b is required.
