Abstract

PURPOSE:To realize conveyance and accumulation of articles, such as a round rod or the like, which are not stabilized on a plane by laterally bridging a shaft, equipped with article pushing wheels on the left and the right, over projected pieces formed at regular intervals on a pair of left and right endless chains. CONSTITUTION:When an endless chain 6 is driven by means of a motor 2 through transmission device 3-5, article pushing wheels 7a, rotatably provided on the left and right of a shaft 7 laterally bridged over projecting pieces 6a opposed to the chain 6, are moved. When the wheel 7a is brought in contact with a central shaft of a crankshaft 13 which is an object of conveyance placed on a rail 11, the shaft 13 is rotatably conveyed through a disc 13b. Then the shaft 13 is stopped and accumulated by means of a control rod 16a of an intermittent feed gear 16. Upon subsequent lowering of a control rod 15a of an intermittent feed gear 15 and raising of the control rod 16a, the shaft 13 is conveyed up to a stopper part 14 and stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chain conveyor that allows articles such as crankshafts and round bars that cannot be placed stably on a flat surface to be stored at necessary locations while being sequentially transferred. This relates to an accumulator device.

As is well known, there are many accumulator devices such as round bars, but all of them are equipped with a mechanism for stably holding the round bar or releasing it. These mechanisms were configured to function separately from the movement of the chain conveyor. Therefore, such conventional devices have a high initial cost and a high running cost, and require a considerable amount of maintenance.

The present invention has been made by paying attention to the above-mentioned points. That is, an object of the present invention is to transport articles that cannot be stably placed on a flat surface, such as a round bar, while sequentially transferring them. An object of the present invention is to provide an accumulator device for a chain conveyor that can accumulate items at a much lower cost than conventional accumulators.

Another object of the present invention is to provide an accumulator device for a chain conveyor, which has a simple structure, allows easy maintenance and inspection, and has a long service life.

Next, an embodiment of the present invention capable of achieving the above object will be described in detail with reference to the accompanying drawings.

1 is a base frame having a height adjustment mechanism 1a at the bottom, 2 is an electric motor, 3 is a driving sprocket driven by the electric motor 2 via a reduction mechanism 4, 5 is a driven sprocket whose tension can be adjusted, and 6 is a driving sprocket 3. 2 shows two left and right endless chains that are wound around a driven sprocket 5, and protrusions 6a are formed at desired regular intervals on the endless chains 6.

Reference numeral 7 indicates a shaft that is horizontally packed between the opposing protrusions 6a of the two left and right chains 6, and there are article pushing wheels 7 on the left and right sides of the shaft 7.
a is rotatably provided.

The base frame 1 is also provided with chain feeding guides 8 and 9.

Reference numeral 10 indicates an underframe that is provided completely in the length direction on the base frame 1 on the outside of the two endless chains 6, and a rail 11 is provided on this underframe. As shown in the figure, it may be fixed to the underframe 10 or it may be provided so as to be movable up and down. As a means for vertical movement, for example, as shown in FIG.
and a rod 12 having an enlarged portion 12a on the rail 11.
are rotatably fitted together, and the threaded rod 12 is connected to the female thread 1.
The rail 11 can be positioned at a desired height by screwing the rail 11 into the rail 0a and rotating the screw rod 12 from side to side.

Reference numeral 13 indicates a crankshaft consisting of a central axis 13a, a number of disks 13b, and a cam 13C provided between the two disks 13b, and both ends of the crankshaft 13 are placed on the rail 11 as shown in FIG. When the article is placed on the article, a part of the article pushing wheel 7a comes into sliding contact with the central shaft 13a as shown in FIG.

In addition, in FIG. 1, 14 is a stopper provided on the base frame 1 at the end of the endless chain 6 on the transfer side;
15.16 is an intermittent feeding device having control rods 15a and 16a which are provided on the front side of the stopper 14 and can move up and down;
17 shows the cover.

In the above configuration, as the endless chain 6 moves in the direction of the arrow, the article pushing wheel 7a also moves in the same direction. When the wheel 7a comes into contact with the central axis 13a of the crankshaft 13 as shown in FIG.
A large number of discs 13b of the crankshafts 13 are connected to the first
When placed on the rail 11 in a state of contact as shown in the figure,
It has been in contact since the beginning. ) The crankshaft 13 moves in the direction of the arrow via the disc 13b, and also the article pushing wheel 7
The crankshaft 13 is transferred while a rotates in the direction of the arrow.

The crankshaft 13 is the control rod 1 of the intermittent feed device 16.
6a, when the feeding is stopped, a number of crankshafts 13 are retained as shown in the figure, and only the endless chain 6 is moved, that is, rotated. In this state, the control rod 15a of the intermittent feeder 15 is lowered between the front part of the crankshaft indicated by reference numeral 13A and the rear part of the crankshaft indicated by reference numeral 13B, and the intermittent feeder 1
6. Raise the control rod 16a. When the time comes, every issue 13
The crankshaft indicated by B is transferred to the 14th section of the thread and stopped. At this point, the crankshaft is moved to the required position by operating the rotor and throat using the sensor, and immediately after this, the control rod 16a is lowered and at the same time the control rod 15a is raised to move the crankshaft 13A to the position 13B. The transportation process is repeated over and over again.

Also, when the crankshaft 13 is large and heavy,
The rail 11 is appropriately lowered via the screw rod 12, and as a result of this lowering, the central axis 13a of the crankshaft 13 is placed in a lower position than in FIG.
a.

Furthermore, in the illustrated example, the shaft 7 having an article transfer wheel 7a is generally cut through a protrusion 6a for each link element constituting the endless chain 6, but these protrusions 6a are The pitch is changed appropriately depending on the size of the transported article.

Since the present invention is constructed as described above, it can be made at a much lower cost than conventional devices, and its simple structure suffices for easy maintenance and inspection, and it has advantages such as a long service life. .
