Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an accumulator device for temporarily storing conveyed objects in drive conveyor equipment, particularly in an accumulation type drive roller conveyor equipment.

[Prior Art] Generally, in conveyor equipment for conveying bottles, for example, as shown in FIG. 5, there is a difference in processing capacity between bottle manufacturing process A and filling process B, so and unloading conveyor 42
A storage area 43 is provided between the two and the bottles 44 are temporarily stored therein. Here, Akiyum Area 4
A guide 45 for smoothly guiding the bottles 44 toward the carry-out conveyor 42 is provided on the outer edge of the carry-in conveyor 41, the carry-out conveyor 42, and the accumulation area 4.
Each of the conveyors 3 is composed of a constantly driven top plate chain conveyor or a normal roller conveyor, so that the bottles 44 carried in are automatically transferred to the accumulation area 4.
3 and are automatically delivered in pairs to the delivery conveyor 42 in a line.

By the way, in such conveyor equipment, since the conveyor is constantly driven as mentioned above, the bottom of the stored and stopped bottles is rubbed against the conveyor surface, damaging the bottles and producing unpleasant noises. There were problems such as: For this reason, an accumulation type drive roller conveyor has been proposed, as known from, for example, Japanese Patent Publication No. 55-16932. According to such a roller conveyor, as shown in FIGS. 6 and 7, the rollers are formed of a large number of divided free rollers 47 that are loosely fitted to the drive shaft 46, so that the bins 44 can be stopped and When a predetermined braking force is applied to the free roller 47, the free roller 47 slips against the drive shaft 46 and its rotation is stopped. Therefore, the bottom surface of the bottle 44 is not rubbed, and the above-mentioned problem is solved.

[Problems to be Solved by the Invention] However, the accumulation type drive roller conveyor still has the following problems. That is, the bottles 44 are constantly transported by the discharge conveyor 4 in the storage area 44.
A portion of the bottle 44 is conveyed toward the second dispensing port and stagnates near the dispensing port, but as this stagnation progresses, the line pressure applied to the stopped bottles 44 from the bottles behind them increases. Here, if the bottles are heavy and strong bottles such as those made of glass, they will be dispensed one after another in a line without any problem even if a strong line pressure is applied, but if the bottles are made of plastic or paper, for example, In the case of lightweight and flimsy bottles such as bottles, if strong line pressure is applied to them, the bottles may be deformed or damaged by falling over, and at the same time the arching phenomenon occurs, where the bottles come into contact with each other and cause a jam. be.

In this way, in conventional conveyor equipment,
Even when an accumulation type drive roller conveyor is used, if the bottles to be conveyed are lightweight and thin, deformation damage to the bottles and arching phenomenon are unavoidable.

Therefore, the purpose of the present invention is to reduce the weight of the transported objects.
To provide a conveyor accumulator device capable of smoothly discharging conveyed articles without damaging them or causing arching phenomenon even if they are thin.

[Means for Solving the Problems] In order to achieve this object, the conveyor accumulator device of the present invention uses an accumulation type drive roller in which similar articles are arranged between an accumulation type inlet conveyor and an output conveyor. In a conveyor that stores items in an accumulation area of the conveyor and delivers them one by one, the accumulation area has at least a pair of parts extending from opposing parts of both side walls of the conveyor toward the area stopping part, respectively, at an angle in the conveying direction. A set of width-aligning running scrapers is provided, and the accumulation area is divided into a plurality of divided areas, and the downstream end wall of the most downstream divided area is inclined in the conveying direction from both side wall ends of this divided area. It is formed of a pair of delivery running scrapers extending toward the delivery conveyor, and is configured to connect the delivery conveyor by providing a row of delivery ports between the opposing ends of the two running scrapers.

[Operation] The articles carried into the accumulation area from the carry-in conveyor are sequentially conveyed downstream by the running scraper without increasing the line pressure in each divided area divided in the conveying direction, and are finally delivered. They are carried out in a single line from the mouth to the delivery conveyor.

[Example] Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, an accumulation area 1 is formed in a rectangular shape with the long side in the conveyance direction, and on the upstream side thereof is a cylindrical container 2 manufactured in manufacturing process A.
Two carry-in conveyors 3 for carrying in the containers 2 are connected, and one carry-out conveyor 4 for carrying the containers 2 sequentially to the next filling process B is connected on the downstream side. Here, the carry-in conveyor 3, the carry-out conveyor 4, and the conveyor of the accumulation area 1 are all constituted by a constantly driven accumulation type driving roller conveyor, and the cylindrical container 2 is made of plastic or paper. There is.

And, the accumulation rate area 1 according to the present invention
A pair of width-shifting running scrapers 5 and 6 are provided in a V-shape, extending from opposing portions of both side walls toward the center of the area, respectively, inclining in the conveying direction. is divided into three divided areas 7, 8, and 9, and the downstream end wall of the most downstream area 9 has a pair of pairs extending from both side wall ends toward the discharge conveyor 4, respectively, at an angle in the discharge direction. A running scraper 10 is formed in a V-shape, and a line of dispensing ports 9a for the cylindrical container 2 is provided between the opposing ends of the scrapers 10. Connected to 4.
Here, the length of the divided area 9 in the transport direction is formed to be shorter than that of the other divided areas 7 and 8, and the gap formed by the opposing ends of the widthwise running scrapers 5 and 6, that is, the divided area The width dimensions Wa and Wb of the discharge gates 7a and 8a of 7 and 8 are at least twice the outer diameter D of the cylindrical container 2, preferably 4 to 5 times, and the width dimension Wc of the discharge port 9a of the divided area 9 is is larger than the outer diameter D and smaller than 2D.

The side-applying running scrapers 5, 6 and the discharging running scraper 10 have almost the same structure except for the captain, and as shown in FIGS. There is. The scraper main body 12 includes a frame 14, a head pulley 16 and a tail pulley 17 (not shown) supported at both ends of the frame 14 via pulley brackets 15, and A drive belt 20 is stretched over a sill slide 19 attached to a frame bracket 18 (see FIG. 3). The drive unit 13 has a machine base 23 fixed to the frame bracket 18 of the scraper body 12 and supported by a support bracket 22.
, a variable speed drive motor 25 equipped with a reducer 24 mounted on this machine base 23 , and this drive motor 2
5, and a pair of throttle pulleys 27 supported by a machine base 23, and a drive belt 20 is stretched between the drive pulley 26 and the throttle pulley 27. and,
When the drive motor 25 is driven, as shown in FIG. 1, the drive belt 20 is configured so that its front side is rotated toward the delivery gates 7a, 8a or the payout port 9a, respectively.

In the accumulator device of the present invention having such a configuration, the containers 2 carried in by the carry-in conveyor 3 are divided into the divided areas 7 of the accumulator area 1,
8, 9 to the downstream side, and finally are carried out in a line from the delivery port 9a to the delivery conveyor 4. Here, the divided areas 7, 8, 9
The accumulator area 1 set in the required storage area is divided perpendicularly to the conveyance direction, and each divided area is set short in length in the conveyance direction, and the width guide or Since the dispensing guides are all formed of running scrapers 5, 6, and 10, the containers 2 are smoothly transported and dispensed, and a sufficient storage capacity is ensured.

That is, in the divided areas 7 and 8, the containers 2 carried in are sequentially conveyed downstream, guided by the drive belts 20 of the width-aligning running scrapers 5 and 6, and guided to the discharge gates 7a and 8a, respectively. Even if the container 2 stagnates near the delivery gates 7a and 8a, the line pressure applied to the container is reduced, so the container can be safely removed from the delivery gate without deforming or overturning, or without causing any arching phenomenon. It is smoothly transported in multiple rows. Furthermore, the container 2 that has been carried out is carried into the downstream dividing area without the line pressure. Furthermore, since the conveyor is formed of an accumulation type roller conveyor, there is no possibility that the bottom of the stagnant containers will be scraped by the rollers and damaged. On the other hand, within the divided area 9, the length in the transport direction is that of the other divided area 7,
8, even if the width of the dispensing port 9a is small, the containers 2 are guided by the dispensing running scraper 10 and are smoothly conveyed in a line from the dispensing port 9a onto the discharging conveyor 4.
