Description

[Detailed description of the invention] Ceiling conveyance system The present invention provides an overhead transport system, in particular a track for carrying a plurality of freight cars, and a suitable A conveying system consisting of a drive member that runs continuously guided by suitable guiding means. related to music.

The above-mentioned transportation systems can be roughly divided into two groups in terms of the transportation mechanism of the freight cars. Ru. In one group, the wagon is substantially permanently connected to the drive member or are connected so that both sides move together, and are commonly used with push-propelled conveying systems. It is called. According to the other group, freight cars are primarily dominated by trucks; It is a structure that connects to the driving member only by friction, and for example, a freight car is placed on the driving member. or by some means to stand still against the drive member, and the freight car and drive unit are Under the frictional force between the materials, the wagon is moved along with the movement of the drive member. this is a transport system called friction propulsion type. As a driving member of the latter frictional engagement , link members made of a suitable synthetic resin material and connected in a chain-like manner so as to be movable with each other. It is commonly used.

Friction-propelled conveying systems are not only useful because they instantly cushion the conveyed items. This is a system that has been in the spotlight for some time. For example, multiple units in one part The conveyed items can be kept close to each other and in contact with some kind of stopper, while still being effective. Collisions can be suppressed without reducing the rate. Such a buffer typically includes a sider. However, this is disadvantageous as it is expensive and requires a large amount of space. Ru.

One of the problems associated with friction propulsion conveyance systems is that the freight car cannot move upward or downward even slightly. If the freight car is tilted in the opposite direction, the frictional engagement of the drive member will be insufficient due to the freight car's own weight and load. Therefore, it is difficult to apply this method to inclined freight cars. In frictional engagement systems, the drive Since the freight car could not slide against the parts, the freight car was tilted upward without control. It can be raised along a track or slid down a downwardly sloping track. I can't do it either. If the freight cars are allowed to move uncontrollably, they will collide and pull each other. There is a risk that it may get stuck or climb onto the next freight car, causing damage to the transported goods.

The frictional engagement between the drive member and the freight car provides a very simple cushioning effect as described above. Nevertheless, in other cases problems may arise purely due to frictional engagement. There is also.

An object of the present invention is to provide a conveyance system that eliminates the above-mentioned problems.

According to the transport system according to the invention, each freight car has a control/lock mechanism. The mechanism is mounted with its operating position at a distance from the truck. It can be freely adjusted by means of controlled controls, and the load can be adjusted in its operating position. The arrangement is such that a pushing engagement is formed between the wheel and the drive member.

If push-propelling engagement is required at the start of conveyance, adjust the operating position of the control means. It may be articulated and then held in a stationary position at the end of the track by interlocking. however , This configuration inevitably requires complicated operations.

In a preferred embodiment of the invention, a control for adjusting the control/locking mechanism is provided. extending the roll means along at least a portion of the conveying system and activating the roll means; by automatically returning the control/locking mechanism to its rest position when , causing the propulsive force engagement to be interrupted.

For example, the member that achieves the push-in engagement may be a member that fits into a hole or groove in the drive member. I can give examples of hooks and bottles that fit together.

A particularly preferred example is to provide a spring-loaded latch in the control/lock mechanism for activation. At this position, the latch and the protrusion of the drive member are engaged with each other.

In order to improve the reliability of the control/lock mechanism, the freight car and drive If it is necessary to form a push-in engagement between members, the movement of the drive member Preferably, braking means are provided for momentarily braking the movement of the freight car.

As an advantage of the invention, the universal properties of conveying systems with friction-propelled carriers are maintained. For example, at a desired location above or below the track, the freight car and driver It is mentioned that a pushing engagement can be formed between the moving members.

Hereinafter, the present invention will be explained in detail based on the accompanying drawings.

FIG. 1 shows a transport system according to the invention with a cargo wagon that can run along a track. It is a perspective view showing one example of a stem.

Figure 2 shows the transport system just before moving the freight car to an upwardly inclined position. FIG.

3 is a perspective view of the transport system of FIG. 2 from the opposite direction; FIG.

FIG. 4 is a perspective view partially showing an upwardly sloping track of the transport system; Ru.

The exemplary transport system includes a truck lO for carrying a plurality of loaded wagons 11; , guided through suitable guide members 13.14 and generally designated by the reference numeral 12. It consists of a drive member that moves cyclically.

The drive member 12 is, for example, a chain-like connecting link made of a suitable synthetic resin material. It has members 12A and 12B, and the link members are movably connected to each other. Ru. The drive member 12 is assumed to move in the direction of arrow A in each drawing, i.e. From right to left in Figures 1 and 2, from left to right in Figure 3, and from left to right in Figure 4. moves from the lower left side to the upper right side.

It should be added that according to the conveying system of the present invention, each of the endless and properly driven It is possible to arrange a plurality of chain-like drive members of the above-mentioned type. these Drive members may be connected one after the other to form a long track or by suitable transitions. If they can be connected to each other via gears, one track can be branched out as a sub-track. It is also possible to open and close two or more tracks simultaneously as a single track. It is Noh. However, these driving members do not constitute the essential part of the present invention. Therefore, detailed explanation thereof will be omitted here. Each of the illustrated freight cars 11 has a front end portion on both sides. It has a pair of rollers 15.1B at its rear end. Roller 15.1B is designed is one driving member] 2 to support the freight car 11 as it passes through the next adjacent driving member. It is arranged to accept. In that case, the roller 15.1B is preferably horizontal At this point, it runs on a guide that has at least a slight angle of inclination to the surface. The freight car 11 loses its propulsion force, rotates by itself, and moves from one drive member to the next drive member. will be moved to.

The freight car 11 is provided with two side walls 17 and 18 fixed to each other with a slight distance from each other. It is. The length of these side walls is the length of two or three links 12A of the drive member, 12B, and between the side walls 17 and 18 there is a control/ A small gap 19 for accommodating the lock mechanism S is formed. The side of each freight car 11 A shaft 20 extends in the direction, and one end of the shaft extends downward and toward the track 10. It is bent on the side surface to form, for example, a transport hook 21. This hook 21 Alternatively, other types of hooks or connecting members may be provided.

The wagon 11 has a pair of upright rectangular sections 22, 23 at its front end. Machiyamagata The rod extends rearward and has a drive yoke 24 pivotally attached to the rear end of the rod. ing.

If necessary, the drive 4 section 25 may be arranged at a distance above the track lO of the freight car 11. It is driven by a control means 26. In other words, freight car 11 is the controller. When passing under the drive yoke 26, the drive yoke 24 is pivoted downward about its axis. let A drive plate 27, which is attached to the top of the drive yoke 24, is attached to the side wall 17. The control/lock mechanism S housed in the gap 19 of 18 is driven, and the mechanism is activated. Activate or hold prestressed prior to activation. Conte When the roll/lock mechanism S is in the operating position shown in FIG. 80, the above engagement relationship is maintained as the drive member 12 moves. 2, that is, while the drive yoke 24 is continuously pivoted to the position of FIG. Freight cars move. In this position the conveying system is frictionally propelled along a certain part of it This means that it has been converted to push propulsion.

As is clear from FIG. 3, the chain links 12A and 12B have one protrusion 28. It is believed that this configuration also performs the same function as in Figure 2. . Furthermore, there is no problem in providing the protrusion 28 on the second or third chain link. It doesn't come.

A spring-loaded latch is provided on the control/lock mechanism S to ensure that the mechanism is in the operating position. and engage the protrusions 2B of each of the chain links 12A and 12B. Both are possible. However, in this configuration, the propulsive force is generated between the freight car 11 and the drive member 12. Use a means to create a transmission engagement, such as a pin that fits into a groove. is essential.

The protrusion 28 is positioned precisely in a straight line with respect to the control/lock mechanism S. Only when the drive yoke 24 swings downward at this point can the mechanism be driven into the operating position. This may lead to a situation where the With such a drive, rapid engagement cannot be achieved. stomach. In order to solve this problem, it is necessary to brake the freight car 11 instantly at the start of push propulsion. A brake piece 29 is provided between the control/lock mechanism S and the protrusion 28. to slightly displace the drive member 12 to a position where the desired drive engagement is achieved. You can configure it as follows.

If push-drive engagement is desired in the respective upper and lower parts of the track, guide 2 It is sufficient to drive the drive yoke 24 by the operation of 6.
