Description

[Detailed Description of the Invention] The present invention relates to a conveyor device in which a cart or the like on which objects are loaded is equipped with a storage mechanism.

Conventionally, floor conveyors (hereinafter simply referred to as conveyors) have often been used to transport the objects mentioned above in the assembly and painting of motorcycles, four-wheeled vehicles, other machines and equipment, etc. There is. However, depending on the conveyor, it is necessary not only to convey the conveyed objects continuously, but also to store the conveyed objects intermittently, in production lines such as assembly and painting. In many cases, this type of conveyor has been developed, improved, and used in the past.

For example, as shown in Fig. 1, a conveyor is provided in parallel on the transport side and a return side, and the conveyed object is stored at a predetermined position while sliding on rollers attached to the conveyor; There are devices (not shown) that have a function of keeping a wire rope running at all times, and automatically unclamping and storing the wire rope.

By the way, the conveyor device according to the present invention is also used for the same purpose as the above-mentioned conveyor, and eliminates the deficiencies of conventional conveyor devices such as oversized equipment, incomplete storage function, and problems with automation. In order to do this, the trolley is equipped with a metal fitting called a tilting dock that has a spring attached to the bottom of the trolley to make a pendulum movement.The tilting dock fulfills the three functions of transporting, returning, and storing the conveyed object, and is suitable for motorcycles, automobiles, etc. The purpose is to automate work and save labor on manufacturing lines for wheeled vehicles, etc.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

Here, we will take a general form of a floor conveyor as an example, and describe the case where parts, etc. to be assembled into the machine body are loaded and transported on the cart 1 of the conveyor. An upper plate 11, a running roller 12 that supports the upper plate 11 and causes it to run on a rail 13, a shake prevention roller 14 that prevents lateral shake during running, and an upper plate 1.
A tilting dock (hereinafter abbreviated as "dock") A, which is rotatably supported on a shaft 15 located below 1.
B, and a stop plate 16. Depending on the case, the trolley 1 may be equipped with docks A and B at the front, a stop plate 16 at the rear, and one or more upper plates 11 in the middle. The conveyor chain 2 can also be connected to the carriages 1, while the conveyor chain 2 runs on the rails 18 via rollers 17,
They are connected by an inverted T-shaped link plate 19 at an appropriate interval, and a conveyor fitting 20 is fixed to the upper part of the inverted T-shaped link plate 19. (Figure 2),
(FIG. 3) Here, to explain the docks A and B in more detail, the docks A and B are rotatably supported by a shaft 15, and are given a torque in one direction by a spring 28. Since it is received by the stopper 21, it is always hanging down perpendicularly to the upper plate 11.

Moreover, the dock A is connected to the middle plate 2 with which the stopper 26 or the stop plate 16 engages with respect to the receiving plate 22-A.
3 and the lower plate 24-A with which the conveyor fitting 20 engages are respectively established vertically, while the dock B is connected to the receiving plate 24-A.
Lower plate 24- with which the conveyor fitting 20 engages with 2-B
B is established vertically. (Figure 5) Furthermore,
As shown in FIG. 4, which is a partial projection view of C-C, the docks A and B are pivotally supported so that the lower plates 24-A and 24-B are positioned symmetrically with respect to each other.
An interlocking plate 29 is fixed to the receiving plate 22-A.

Conveyance fitting 20 by movement of conveyor chain 2
To explain the operation of the dogs A and B, first, the conveying metal fitting 20 approaches the dog B and engages with the inclined or curved lower plate 24-B.
The dock B, which is pivotally supported, rotates independently and passes through the conveyor fitting 20. The conveyor fitting 20 that has passed through the lower plate 24-B of dock B is transferred to the lower plate 24-A of dock A.
engage with. In this case, no torque is generated to rotate the dock A, and the cart 1 is transported in that state. Therefore, when the cart 1 that has been transported to a predetermined position is stopped, the stopper 26 engages with the middle plate 23 of the dog A, and rotates the dog A, thereby connecting the lower plate 24-A and the transport metal fittings. 20. Once stopped, the dock A of the trolley 1 rotates by itself due to the engagement with the stopper 26, and is connected to the dock B via the interlocking plate 29.
is also rotated, resulting in a state as shown by the dotted line in FIG.

Therefore, the conveyor fitting 20 is attached to the lower plates 24-A, 24.
- Pass smoothly without contacting B. Furthermore, the subsequent carts 1 transported by the transport fitting 20 are stopped by the stop plate 16 attached to the rear of the previous stop cart 1 performing the same action as the stopper 26, and the number of subsequent carts 1 is sequentially stopped. to store.

When a predetermined work has been completed and the cart 1 is no longer needed, the stopper 26 is manually or mechanically released, and the transport fitting 20 engages with the lower plate 24-A of the dock A, thereby being transported.

Next, the truck 1, which has turned to the return side via the sprocket, pulls the docks A and B of the truck 1 by the spring 28.
It is always established vertically by the force of , and exhibits the same effect as the relationship between the docks A, B and the transport fitting 20 on the transport side described above, and is transported, stopped, and stored by the conveyor chain 2.

As described above, the conveyor device has the functions of conveying, stopping, and storing by means of the conveying metal fittings 20, docks A and B, stoppers 26, and stop plate 16. However, when the conveying side wants to manually stop the conveyor at any position, it is necessary to It is not possible to use the stopper 26 attached to the top plate 11, and it is necessary to put your hand under the top plate 11 to detach the dock A from the transport fitting 20, but this poses a safety problem and requires time for adjustment. Therefore, the docks A and B can also be operated from the upper surface of the upper plate 11 of the truck 1. The above operation must be easy; for example, as shown in FIGS. 6a and 6b and FIG. 7, a hole 31 is made in the center of the upper plate 11, and a rubber button 32 is attached to the hole 31. Therefore, if you want to stop the cart 1 that has been transported at an arbitrary position, press the button 32 to deform it as shown in FIG. break away. Conversely, when the user releases the button 32, the elasticity of the rubber causes the spring 28 to return the cart 1 to its original position, and the cart 1, which has been temporarily stopped, is transported again by the transport fitting 20.

As mentioned above, there are docks A and Dock A below the trolley 1.
By pivotally supporting B in a pendulum shape, it is possible to accurately transport the trolley 1 using the conveyor fitting 20 of the conveyor chain 2, stop it at a predetermined position, and store a certain number of trolleys.

Moreover, due to the action of the spring 28, conveyance can be carried out by the same conveyor chain 2 on the return side without requiring any special control device, and furthermore, once the preceding cart 1 stops, the following cart 1 is transferred to the preceding cart 1. Dock A and the transport fitting 20 with the stop plate 16 of 1
Immediately releases the engagement relationship with the preceding cart 1, the following cart 1 stops following the preceding cart 1, a rear-end collision of the cart 1 is prevented, and the succeeding cart 1 sequentially stops following the preceding cart 1, stored. Furthermore, it is easy to stop the cart 1 at any location by operating the button 32.

In addition, when the conveyor line is inclined and the cart 1 attempts to move on its own, the lower plate 24-A of the dock A hits the conveyor metal fitting 20 and not only pulls and conveys the cart 1, but also the conveyor metal fitting 20 Since the lower plate 24-B prevents the cart 1 from moving on its own, the cart 1 can always be pulled and transported at the same speed as the conveyor chain 2. In addition, when dock A rotates due to engagement with stopper 26 or stop plate 16, dock B also rotates due to interlocking plate 29, so the conveyor fitting 20 does not come into contact with docks A and B, and there is no unnecessary noise.
Furthermore, in contrast to the conventional conveyor in which the transport side and the return side are parallel to each other in a plane, the trolley 1 is submerged below the conveyor chain 2 on the return side and rotates, so the installation area of the conveyor is reduced, and the entire factory The conveyor according to the present invention is an excellent conveyor device that satisfies the needs of a conveyor device that requires efficient use of site area and a storage function.
