Abstract

PURPOSE:To permit switching passages in a narrow space by installing a return passage directly under a going passage and returning conveyance flat carts in the inverted state, in a line-shaft driving type transfer apparatus. CONSTITUTION:When a line shaft 4 is turned in the direction of arrow 31, a conveyance flat car 3 on a going passage 1 advances in the direction of arrow 32 by a carrying roller 8 inclined by 45 degrees for the shaft 4. When the flat car 3 transfers onto the guide rail 12 of a passage switching means 10 at the terminal of the going passage 1, the flat car 3 is stopped by a stopping means not shown in the figure. Then, a rotary frame 11 is turned by 180 degrees by a motor 16, and the guide rail 12 is connected to the guide rail 6 on the return passage 2. Since the flat car 3 is set in the inverted state through the above-mentioned operation, if a stopping means is released, the flat car 3 in the inverted state is return 35 through the return passage directly under the going passage 1 by a driven roller 8. With such a constitution, switching of the transfer passages is permitted in a narrow space by installing the going and return passages.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a line shaft-driven conveyance device, that is, a line shaft is disposed along the conveyance vehicle travel path, and the conveyance vehicle has the above-mentioned ? Pressed diagonally against 4 in-shafts'J
A conveying device is provided with a driven roller, and by the rotation of a line shaft, a thrust force is applied to the conveying cart in the direction of the traveling route through the driven roller, and the conveying vehicle is moved by 10 degrees from the end of the conveying line. Provided is a conveyance device in which a return path for returning the empty conveyance truck to the starting end of the conveyance line is arranged directly below the outbound path that becomes the conveyance line, and the empty conveyance truck is moved backward in an inverted state. It is something that

An embodiment of the present invention will be described below with reference to the attached illustrative drawings. In FIG. route,
Reference numeral 6 denotes a transport vehicle, and 4 represents a line shaft for propelling the transport vehicle, which is disposed at an intermediate position between the forward route 1 and the return route 2 in parallel to the route direction.

As shown in FIG. 2 and FIG.
A horizontal axis wheel 7 that fits into the kite rail is supported on both left and right sides of the conveyor vehicle 6, and a driven roller 8 that presses against the line shaft 4 is also supported. In the 2nd v, 9 is a vertical axis wheel for preventing the left and right sway of the transport vehicle 6.

At both ends of the outbound route 1 and the inbound route 2, there are provided storage vehicle route switching means 10, as shown in FIG. 4. This means 10 is rotatable around the line shaft 4. This rotating frame 11018
By rotating every 0 degrees, the guide rail 5 of the outgoing route 1
Two sets of groove-shaped guide rails 12 and 13 are constructed, which are sequentially connected to the guide rail 6 of the conventional route 2, and the rotating frame 11 is attached to the rotating frame 11 concentrically with the line shaft 4. 14 and a gear 15 meshing therewith, a motor 16 is provided which rotates every 180 degrees,
Further, a transport vehicle stopping means 17 shown in FIGS. 6 and 7 is provided on the rotating frame 11. Reference numeral 18 denotes a plurality of supporting rollers that rotatably support the rotating frame 11.

As shown in FIG. 5, the driven roller 8 is supported by a movable member 20 which is supported by a vertical shaft 19 at the bottom of the transport vehicle, and this movable member 20 is supported by a biasing means '21 inside a compression coil spring. , is held in the first driven posture in which the abutting portion 23a abuts against the cutting F collar 22. Further, the side of the biasing means 21 opposite to the movable member 20 side is pivotally connected to a switching arm 24, and the switching arm 24 is brought into a first position in contact with the stopper 25a by the biasing force of the biasing means 21. Retained. 26 is a cam driven roller that is pivotally supported on the switching γ-mem 24, and 27a and 27b are cam driven rollers that are pivotally supported on the movable member 20.

In FIG. 5, reference numeral 28 denotes a stopping means disposed at the transport vehicle stopping position on the outgoing route 1, and the operating position shown by the solid line and the retreating position shown by the imaginary line by the cylinder unit 1 etc. not shown. It is equipped with a cam rail 29 that can be freely switched between positions.

By rotating the line shaft 4 in the direction of the arrow 61)j shown in FIGS. 2 and 5 by the motor 5o shown in FIG. As shown in FIG. 5, the line shaft 4
By being in the driven posture of moving at an angle of 45 degrees with respect to the direction of arrow 52, the robot moves forward in the direction of arrow 52. When the conveyance cart 5 moving in this manner is to be stopped at a stop position on the outbound route 1, the cam rail 29 at the stop position is switched to the operating position shown by the solid line in FIG. The movable member 20
The cam driven roller 27a rides on the cam rail 29 -L
Then, as shown by the imaginary line in FIG. 5, the movable member 20 rotates and the driven roller 8 is switched to the free rolling position 1 in which the driven roller 8 is flush with the line shaft 4.

Therefore, the rotation of the line shaft 4 simply makes the driven roller 8 extremely light, so that no thrust is applied to the transport vehicle O, and the transport vehicle 6 automatically stops at its stop position.

Even in this stopped state, the biasing means 21 biases the movable member 20 in the direction of returning it to the original first driven position, as shown by the imaginary line in FIG. 5, so that the cam rail 29 cannot be returned to the retracted position. As a result, the movable member 20 returns to the first driven position in which the contact portion 25a contacts the stopper 22, and
Since the driven roller 6 returns to its original driven position, the m-win truck 3 moves again in the direction of the arrow 32.

As described above, the transport vehicle 6 moving in the direction of the arrow 32 on the outgoing route 1 moves along the route I! When the route switching means 10 at the 8th end also transfers to the guide rail 12 as shown in FIG. Automatically stop on 12.

This stopping means 17 utilizes a cam rail 33 that is the same as the cam rail 29 of the stopping means 28 shown in FIG.
4, via the cam driven roller 26, from a first position in which it contacts the stopper 25a to a second position in which it contacts the stopper 25b.

Therefore, as shown in FIG. 6, the transport vehicle 5 transferred onto the guide 1 rule 12 of the route switching means 1o is operated by the cam rails 3 to 5 of the stopping means 17 to achieve the action explained based on FIG. As a result of the similar action, the driven roller 8 is switched to an idling position parallel to the line shaft 4 and automatically stops on this guide rail 12, but at the same time, the cam driven roller 26 presses the cam plate 34 relatively. and the switching arm 24 is moved to the stopper 25.
It is switched to the second posture in which it contacts b. As a result, the biasing direction of the biasing means 24 with respect to the movable member 20 is switched, but the two cam driven rollers 27a, 2 of the movable member 20
7b are both in contact with the cam rail 3i5, the movable member 20 is not affected by the biasing force of the biasing means 24, and is held in a state in which the driven roller 8 is parallel to the line shaft number.

In such a state, the rotating frame 11 shown in FIG. 4 is rotated 180 degrees by the motor 16, and the guide rail 12
is connected to the guide rail 6 on the outbound route 2. As a result, the carriage 6 stands upside down, but since it rotates around the line shaft 4, the driven roller 8 of the lllll type 3 rotates around the line shaft 4 while remaining in contact with the line shaft 4. However, it comes into pressure contact with the lower side of the line shaft 4.

Next, as shown in FIG. 7, by switching the cam rail 56 to the retracted position, the movable member 20 is switched to the second driven position in which it abuts the contact portion 25b or the stator bar 22 by the urging force of the urging means 24. It will be done. Therefore, the driven roller 8 assumes a driven posture inclined at an angle of 45° in the opposite direction, and is moved to the conveyor carriage 3 by the line shaft 4 rotating in the direction of arrow S1 and the driven roller 8 diagonally pressed against the line shaft 4. The direction of the applied thrust is reversed, and the transport vehicle 6 starts in the opposite direction of the arrow 55.

In this way, the transport vehicle 6 is transferred to the route switching means 10.
The user transfers from the guide rail 12 to the guide rail 6 of the backward route 2 in an inverted posture, and moves on this backward route 2 in the direction of arrow 35. When the carriage 6 is to be stopped on this return route 2, a stopping means similar to the stopping means 28 shown in FIG. 5 may be provided at the carriage stopping position.

From the end of outbound route 2 to the beginning of outbound route 1! M carriage 3
The action of transferring the route switching means 1 at the corresponding position
0, the same procedure as described above is performed, and the conveyance carriage 6 is returned to the upright position, and the movable member 20 is returned to the first driven position again, and is sent out to the guide rail 5 on the outgoing route 1.

As shown in FIG. 8, when the line shaft 4a for the outbound route and the line shaft 4b for the inbound route are provided separately, both in-shafts 4a and 4b are driven in opposite directions. By doing so, it is no longer necessary to change the direction of the driven roller 8 as in the above embodiment, and the movable member 20 can be placed in a driven position in which the abutting portion 25a contacts the stopper 22 and in a position in which the driven roller 8 is parallel to the line shaft. It suffices to configure it so that it can rotate only between the two positions, and to simply bias it toward the driven position using a spring.

The present invention can be implemented as described above, and is capable of moving an empty transport vehicle backwards in an inverted position on a return route arranged directly below the forward route of the transport vehicle, and furthermore, When transferring the carrier from the end of the route to the end of the return route or vice versa, the carrier is configured to turn around the axis in the route direction. In particular, as shown in the embodiment, when sending a conveyance vehicle into this route switching means or sending a conveyance vehicle to an outbound route or an inbound route, the outbound route or inbound route is used. It is also possible to use the extension of the line shaft for propulsion of the conveyor cart as is.
