Description

[Detailed description of the invention] Industrial field of application The invention is structured so that stations placed at appropriate locations in a building are connected by a track, and a self-propelled transport vehicle is guided by the track. The present invention relates to track-type transport vehicle equipment, and particularly to a right-angle conversion device for branching a transport vehicle from a transport track to a branch road at a branching portion and carrying it into a station.

Conventional technology Conventional track-type carrier equipment is shown in Figures 1 and 2.
As shown in the figure, a transport vehicle 1 is configured to move while being guided by a track 2. The transport vehicle 1 has a pair of left and right guide wheels 4 at the bottom of the vehicle body 3.
4, 4, 4, a storage container 5 for storing objects to be transported is fixed to the upper part of the vehicle body 3, and the vehicle body 3
Inside, there is a motor 7 that is driven by receiving drive power and control signals input from collectors 6, 6, and 6 attached to the bottom, and two types of drive wheels 9 that are connected to the motor 7 via a reducer 8. , 9' are provided.
The said track 2 has the said guide wheels 4, 4, 4, on both sides.
4 are provided, and a running surface 11 is provided between both the guide parts 10, 10.
are formed on the running surface 11, and the current collectors 6, 6,
Power supply rails 12, 12 for supplying driving power and a power supply rail 12' for transmitting control signals are laid such that they can be in constant contact with the power supply 6. Further, one of the driving wheels 9, 9, is mounted on the running surface 11, and the transport vehicle 1 is driven by the drive wheel 9. The other drive wheel 9' is a gear, and when the track is inclined or curved, it is meshed with a rack (not shown) laid on the running surface 11 of the section. This is to ensure smooth and reliable driving.

Further, as shown in FIG. 3, the right angle conversion mechanism of the branching part has a branching track formed in an arc shape, and the end of the branching track is arranged in a direction parallel to the conveying track 2.
Generally, after the transport vehicle 1 is branched, the course of the transport vehicle 1 is gradually changed, and finally the transport vehicle 1 is transported in a perpendicular direction.

Problems that the invention aims to solve: Each station is installed in a convenient location for handling the station, and the right angle conversion device needs to be installed adjacent to a wall etc. due to the structure of the building etc. In many cases, there was no space available to bend the branched track into an arc shape.

In addition, in order to reduce the space occupied by the branch section, as shown in Fig. 4, the transfer track is cut out by a certain length, and this cut-out conversion track is used as a branch line arranged perpendicularly to the transfer track. In order to connect to the track, use the notched center of the conversion track as a fulcrum.
One that could be rotated 90 degrees was considered, but
In this case, between the transport track on the branch road side and the other transport track among the pair of transport tracks that are the reciprocating route,
The notched conversion track must be spaced a certain distance apart so that it can rotate, and the notch edge, both ends of the conversion track, and the end of the partial track must be formed into an arc shape on the conveyance track, which saves time and money. There was a problem with the extra cost. Furthermore, similar to the above, in order to reduce the space occupied by the branch part, it was considered that the branch part could be rotated 90 degrees as shown in Fig. The problem is that the notch edge of the track, both ends of the convertible track, and the end of the partial track must be formed into an arc shape, and the rotation fulcrum is far away from the center of gravity of the convertible track, and the supporting member must be made strong. However, there is a problem in that a large space is required for arranging the supporting members and the like.

The present invention solves the above problems and makes it possible to connect a transport track and a branch track extending perpendicularly to the transport track on a horizontal plane in a small space. It is an object of the present invention to provide a right-angle conversion device at a branch part of a transport vehicle equipment, which does not require special work.

Means for Solving the Problems In order to achieve the above-mentioned purpose, the present invention, for example, moves a transport vehicle running on a transport track installed in a building to a branch road leading to a station where it can be placed at an appropriate location in the building. In a conveyance trolley facility that can arbitrarily branch and convey, there is a diversion track formed to a certain length so as to match a notch provided in the conveyance track of the branching part, and a diversion track that is on a horizontal plane with respect to the conveyance track. a moving mechanism capable of moving at right angles,
and a right-angle conversion mechanism that rotationally displaces the conversion track by 90 degrees on a horizontal plane during linear movement by the moving mechanism, and the conversion track after the movement is arranged so as to connect to the branch track.

Operation When the transfer vehicle stops on the transfer track, the transfer track is linearly moved a certain distance to the outside of the transfer track, rotated 90 degrees at the moved position, and then transferred to the transfer track. It is further moved linearly toward the end of the branch track extending in the perpendicular direction to connect the branch track of the conversion track. The notch edge, both ends of the diversion track, and the end of the branch track can be formed into straight lines, making the machining easy.

Embodiments Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 6 to 10 of the accompanying drawings.

Note that the transport vehicle and its respective members and the members attached to each track in this embodiment have the same configuration as that used in the explanation of the conventional example, so a detailed explanation thereof will be omitted. Furthermore, when describing this embodiment, the same reference numerals as in the conventional example will be used.

The transport vehicle equipment is connected to transport tracks 2a, 2a installed in the building and a station (not shown) placed at an appropriate location in the building, and
a, 2a, a branch track 2c is arranged to extend in a direction perpendicular to the horizontal plane with respect to one of the transport tracks 2a, which has a cutout 21 in the branch part, and It has a transport vehicle 1 that can run on a track 2c, and a right angle conversion device 20 disposed between the transport track 2a and the branch track 2c.

The orthogonal conversion device 20 is provided so as to correspond to the branch part of the transport track 2a, and converts the transport cart 1 from the transport track 2a to the branch track 2c.
In order to make the transition, the conversion track 2b has a constant length that can match the notch 21. The notch 21
, both ends of the diversion track 2b, and the end of the branch road 2c are each formed into a straight line. The right angle conversion device 20 also has a right angle conversion mechanism for rotationally displacing the conversion track 2b in a right angle direction on a horizontal plane. The right angle conversion mechanism is fixed at the upper end at the center of the bottom of the conversion track 2b, and has a pinion 22 in the middle part and guide rollers 23', 23', 23' and guide rollers 23'', 23' on both sides at right angles to each other.
A rotating shaft 24 to which a guide member 23 having diameters of 3" and 23" is fixed, and a guide rod rotatably supporting the rotating shaft 24 and extending in a direction perpendicular to the conveying track 2a on a horizontal plane. 25, a moving member 27 having a bearing 26 which is movably fitted in the moving member 25, and a moving member 27 along the moving path of the moving member 27 and the conveying track 2a.
The pinion 2 is located at a suitable distance from
A rack 28 is provided within the moving range of the moving member 27, which is fixed to a guide plate 28' erected along the moving path of the moving member 27 so as to mesh with the moving member 27. Note that the guide rollers 23', 2
3', 23' not only act as a guide for the moving member 27, but also serve as electrical contacts, and are connected to the transport track 2a.
When in the state shown in FIG. 8 where it is fitted into the notch 21 of
The conversion track 2b is configured to be connected to the electrical system of the transport track 2a. Further, the guide rollers 23'', 23'', 23'' are also
3', 23', and 23', it not only functions as a guide for the moving member 27, but also serves as an electrical contact point.
When in the state shown in FIG. 10 in which it is connected to the branch track 2c, the diversion track 2b is configured to be connected to the electrical system of the branch track 2c. Furthermore, the right angle conversion device 20 is provided with a moving mechanism for moving the moving member 27. The moving mechanism includes a drive gear 3 connected to a motor 31 via a speed reducer 30 on a mounting plate 29 erected parallel to the guide rod 25.
2, a free gear 33 disposed at an appropriate distance from the drive gear 32, and an endless chain 34 extending between the drive gear 32 and the free gear 33;
A rod-shaped arm rod 35 is provided, one end of which is pivotally connected to the bearing 26 of the moving member 27, and the other end of which is pivotally connected to the endless chain 34. Since the moving member 27 and the endless chain 34 are connected by the arm rod 35 in this way, as the endless chain 34 rotates, the moving member 27 moves along the guide rod 25 on the conveying track on the horizontal plane. It can move in a direction perpendicular to 2a. Then, in the state shown in Figure 8,
When the moving member 27 moves downward in the drawing, the conversion track 2b moves linearly while remaining parallel to the transport track 2a until the pinion 22 reaches the rack 28.
While moving while meshing with the shaft, it rotates 90 degrees on the horizontal plane and becomes in the state shown by the chain line in Figure 9. The conversion track 2b continues to move directly in the rotationally displaced state and reaches the state shown in FIG. 10. In this way, the diversion track 2b remains parallel to the transport track 2a until it leaves the transport track 2a, and after the rotational displacement, it reaches the branch track 2c in the displaced state. , both ends of the switching track 2b, both edges of the notch 21, and the end of the branching track 2c may be formed linearly as described above. Furthermore, when the endless chain 34, which is the part to which one end of the arm rod 35 is pivoted, reaches the outer end of the free gear 33 (upper end, lower end in FIG. 6), the end of the conversion track 2b comes into contact with the end of the branch track 2c. (See Fig. 10) On the other hand, when the endless chain 34, which is the part to which one end of the arm rod 35 is pivoted, reaches the outer end of the drive gear 32 (upper end in Fig. 6), the conversion track 2b is used for conveyance. It is adapted to fit into a notch 21 of the track 2a (see FIG. 8). In addition, the rack 28 is arranged so that the above-mentioned operation is not hindered.
The rotation of the switching track 2b is arranged at a position where it is not blocked by the conveying track 2a and the branching track 2c.

8 to 10 show the operating sequence of the above embodiment, and the operation of the right angle converter 20 will be explained below with reference to these drawings.

Now, in a state where the conversion track 2b is located in the notch 21 of the transport track 2a as shown in FIG. 8, a sensor (not shown) attached to the side of the transport track 2b near the notch 21 It is actuated by the passage of the carrier vehicle 1, and the carrier vehicle 1 stops on the conversion track 2b. Here, the motor 31 is activated and the endless chain 34 starts rotating, and the moving member 27 and the conversion track 2b interlocked with the endless chain 34
is guided by the guide rod 25 and moves linearly in the direction of the arrow in FIG. During this movement, guide plate 2
8' includes one guide roller 23' of the guide member 23;
23' and 23' are in contact with each other, moving linearly in a direction perpendicular to the conveying track 2a, and maintaining a state parallel to the conveying track 2a. Then, when the moving member 27 has moved a certain distance, the ninth
As shown in the figure, the pinion 22 fixed to the rotating shaft 24 of the movable member 27 meshes with the rack 28, and as the pinion 22 moves, the pinion 22, the rotating shaft 24, and the conversion track 2b are rotated 90 degrees on a plane. The state is shown by the chain line. The conversion track 2b continues to move linearly even after the rotational displacement and is stopped when a limit switch (not shown) is turned on in the state shown in FIG. 10 in which it is connected to the branch track 2c. During movement after this rotational displacement, the other guide roller 2 is attached to the guide plate 28'.
3'', 23'', and 23'' are kept in a position where they are in contact with each other and are properly connected to the branch track 2c. Note that when the conversion track 2b and the branch track 2c are connected to each other, the guide rollers 23 ″,23″,2
3", and is also electrically connected to the transport vehicle 1
can be transferred from the diversion track 2b onto a branch track 2c leading to the destination station.

Note that the right angle conversion device 20 in the above embodiment
can be changed to a structure different from the pinion 22 and rack 28 described above as long as it rotates the conversion track 2b by 90 degrees on a horizontal plane. For example, in the right angle conversion mechanism, instead of the pinion 22, two bars are L at right angles to each other.
A cam bent in the shape of a letter is provided, and the bent portion of the cam is fixed to the rotating shaft 24.In place of the rack 28, a lever that can come into contact with the inside of each bar of the cam is provided on the guide plate 28. It can be replaced with one that protrudes from ′. In the right angle conversion mechanism constructed in this way, as the moving member 27 moves, the cam rotates 90 degrees while contacting the lever, and the conversion track 2b is rotationally displaced. For example, in the right angle conversion mechanism, instead of the pinion 22, a circular cam with a rubber plate provided on the outer periphery is attached to the rotation shaft 24;
The rack 28 may be replaced by a friction portion protruding from the guide plate 28' so as to be able to contact the rubber plate of the circular cam. The friction part has a length of one quarter of the outer circumference of the circular cam, and a rubber plate is attached to the outer surface. When the cam comes into contact with the friction portion, the circular cam rotates 90 degrees, and the conversion track 2b is rotationally displaced.

Effects of the Invention As described above, the present invention enables the transfer vehicle to be converted between the transfer track and the branch track in a small space, and also allows the transfer of the transfer track at both ends of the transfer track and the branch track. Since the end of the track can be formed in a straight line, the molding process for each track is simple and advantageous in terms of cost.
