  The present invention provides a main transport device that sequentially transports a plurality of types of articles, a plurality of branch transport devices branched from the main transport device, a mounting body arranged for each type of the articles, and the branch transport device The present invention relates to a loading facility provided with a loading robot for loading the above articles on the above-mentioned body by type.

  The above loading facilities are used in production facilities, sorting facilities, etc., and the articles sequentially conveyed by the main conveyance device are branched and conveyed to a plurality of branch conveyance devices, and are conveyed by the branch conveyance devices. For loading an article to be loaded for each kind of article on a mounting body by a loading robot.

And in what is used for a production facility, the articles | goods produced with a production facility are conveyed sequentially by a main conveying apparatus, and are loaded on a mounting body for every kind of articles | goods as a kind of articles | goods, for example. I am doing so.
Moreover, in the thing used for the sorting equipment, the articles to be shipped to the transport destination are sequentially transported by the main transport device, and are loaded on the mounting body as the types of the articles, for example, for each transport destination of the articles. I have to.

  In such a loading facility, conventionally, the branch conveyance device is configured to convey one type of article, and the branch conveyance device and the mounting body are provided in a one-to-one correspondence, In some states, the number of branch transfer devices in charge of loading is the same, and among the plurality of branch transfer devices, there is a type in which which branch transfer device is responsible for loading (for example, , See Patent Document 1).

JP 2002-2928 A

  However, in the above conventional loading facility, the loading robot simply loads any of the branch transfer devices among the plurality of branch transfer devices with the same number of branch transfer devices in charge of loading. Since the person in charge is only classified, there is a possibility that inconvenience may occur when there is a height difference in the frequency of articles conveyed by the main conveying device.

In other words, in the main conveyance device, how much and what kind of articles are conveyed changes as necessary, so that there is a difference in the frequency of articles conveyed by the main conveyance device.
In particular, in production facilities, the number of articles to be produced is changed according to the degree of sales, so in a loading facility used for production facilities, the frequency of well-sold articles being conveyed by the main conveyor increases. Thus, the frequency with which articles that are not sold well are conveyed by the main conveying device is lowered, and the frequency of the articles conveyed by the main conveying device is different in height.
Further, even in the loading facility used for the sorting facility, a difference occurs in the number of articles to be conveyed depending on the conveying destination, so that a difference in height occurs in the frequency of articles conveyed by the main conveying device.

Then, when there is a height difference in the frequency of articles conveyed by the main conveying device, the high frequency branch conveying device that conveys articles that are frequently conveyed by the main conveying device has an interval in which the articles are conveyed. Since the length is shortened, there is a possibility that the loading operation cannot be performed accurately due to, for example, an article staying in the branch conveyance device.
Therefore, it is required to increase the loading processing capacity in the high-frequency branch conveyance device.

In the above conventional loading equipment, it is conceivable to increase the processing capacity of loading in the high-frequency branch transfer device by reducing the number of branch transfer devices in charge of each loading robot. In this case, the number of loading robots will increase, which will increase the cost.
In addition, in the low-frequency branch conveyance device that conveys an article that is less frequently conveyed by the main conveyance device, the interval during which the articles are conveyed is long, so that the time during which the loading robot does not perform the loading operation becomes long. There is a risk that efficient loading work cannot be performed.
In addition, in the low-frequency branch transfer device, if the number of branch transfer devices in charge of each loading robot is reduced, the time during which the loading robot does not perform the loading operation becomes long. As the number of installations increases, the disadvantage of increased costs becomes prominent.

  In addition, by providing an aligning device that can change the order in which the articles are conveyed while temporarily storing the articles in the middle of the conveyance path of the main conveying apparatus, a difference in the frequency of the articles conveyed by the main conveying apparatus occurs. Although it is possible to avoid it, in this case, an alignment device must be provided, resulting in a complicated configuration and an increase in cost.

  The present invention has been made paying attention to such a point, and an object thereof is to provide a loading facility capable of reducing the cost while performing an efficient loading operation.

A first characteristic configuration of the loading facility according to the present invention is arranged for a main transport device that sequentially transports a plurality of types of articles, a plurality of branch transport devices branched from the main transport device, and the types of the articles. Loading equipment provided with a loading robot and a loading robot for loading the article on the branch transfer device into the placing body described above for each type,
Of the plurality of types of articles, the plurality of branch conveyance devices conveys high-frequency branch conveyance devices that are frequently conveyed by the main conveyance device, and among the plurality of types of articles, the main A low-frequency branch conveyance device that conveys a low-frequency type article to be conveyed by a conveyance device, and the loading robot has an arm portion that can swing around a horizontal axis on a pivotable base And a high-frequency load that is provided with a gripping portion that is provided at the tip of the arm portion and grips an article, and in which the loading robot loads the article on the high-frequency branch transport device. It is composed of a loading robot and a low-frequency loading robot that loads articles on the low-frequency branch conveyance device, and the high-frequency branch conveyance device is more than the low-frequency branch conveyance device. , Fewer types of goods The high-frequency loading robot is configured so that the number of articles that can be loaded in one loading operation is larger than that of the low-frequency loading robot. The type is the type of the article, and the high-frequency branch transfer device is configured to transfer one type of article, and the low-frequency branch transfer device is configured to transfer two or more types of articles. The high frequency loading robot is configured to load two or more items in one loading operation, and the low frequency loading robot is configured to perform one loading operation. It is comprised so that articles | goods may be loaded one by one by operation | movement, The loading part which mounts the said mounting body is arrange | positioned for every kind of article | item, With respect to one said high frequency branch conveyance apparatus One loading part is arranged and one said low frequency branch conveyance In that a plurality of loading portions vary depending on varieties of the article relative to the location it is located.

  That is, in the high-frequency branch transfer device, the high-frequency loading robot loads the mounting body for each type of article, and in the low-frequency branch transfer device, the low-frequency load transfer device. Since the robot loads on the mounting body for each type of article, the article transported by the main transport device can be loaded on the mounting body for each type such as its type and transport destination. .

  And since the high-frequency branch transport device has fewer types of articles to be transported than the low-frequency branch transport device, the high-frequency load robot is less than the low-frequency load robot. The number of types of articles handled in the loading operation can be reduced, and the number of types of articles handled in the loading operation can be differentiated in a state corresponding to the frequency of articles conveyed by the main conveyance device. .

Therefore, since the number of types of articles handled by the high-frequency loading robot is small in the high-frequency branch transfer device, it is possible to reduce the burden on the high-frequency loading robot. The loading operation can be performed accurately without increasing the number of loading robots installed.
Moreover, in the low-frequency branching and conveying device, since the interval at which articles are conveyed is long, the burden on the low-frequency loading robot is originally small, so the types of articles handled by the low-frequency loading robot By increasing the number, the loading operation can be performed while shortening the time during which the loading robot does not perform the loading operation as much as possible, so that the efficient loading operation can be performed.

  From the above, between the high-frequency loading robot and the low-frequency loading robot, the number of types of articles handled in the loading operation in a state corresponding to the frequency of articles conveyed by the main conveyance device Therefore, even if there is a height difference in the frequency of articles to be transported by the main transport device, the loading operation can be performed accurately without increasing the number of loading robots installed. As a result, it has become possible to provide a loading facility capable of reducing the cost while performing an efficient loading operation.

In addition, since a high-frequency loading robot can load more articles in a single loading operation than a low-frequency loading robot, a high-frequency loading robot is a low-frequency loading robot. The processing capacity for loading can be increased as compared with the loading robot.
Therefore, it is possible to make a difference in the processing capacity of loading between the high-frequency loading robot and the low-frequency loading robot in a state corresponding to the frequency of articles conveyed by the main conveyance device. As a result, it is possible to further reduce the cost while performing a more efficient loading operation.
Furthermore, the high-frequency loading robot can load two or more articles of one type conveyed by the high-frequency branching and conveying device onto the mounting body at the same time. Two or more kinds of articles transported by the frequency branch transport device can be loaded on the mounting body one by one.
Accordingly, two or more types of articles that are frequently conveyed by the main conveying device can be loaded on the mounting body at the same time, and one type of articles that are less frequently conveyed by the main conveying device are one by one. Since it can load on a mounting body, it will be able to perform loading operation | work in the state corresponding to the height difference of the frequency conveyed with a main conveying apparatus, and it will become useful as a loading installation.

According to a second characteristic configuration of the loading facility according to the present invention, the high-frequency loading robot is configured to load the article from a plurality of the high-frequency branching and conveying devices onto the mounting body. The low-frequency loading robot is configured to load the article on the above-described object from one of the low-frequency branching and conveying devices.

That is, the high-frequency loading robot can load a plurality of high-frequency branch transfer devices on a plurality of mounting bodies for each type of article. For high types of articles, one high-frequency loading robot can handle loading on a plurality of mounting bodies.
In addition, a low-frequency loading robot can load a plurality of mounting bodies from one of the low-frequency branch transfer devices by transferring a plurality of types of articles with the low-frequency branch transfer device. Therefore, it is possible to take charge of loading on a plurality of mounting bodies with a single low-frequency loading robot for a low-frequency type of article conveyed by the main conveyance device.

  Therefore, since a single loading robot can load multiple types of articles on the mounting body for each type, the number of loading robots can be reduced and the cost can be reduced. It can be planned.

A third characteristic configuration of the loading facility according to the present invention is that the main transport device is configured to sequentially transport a plurality of types of articles produced in the production facility.

That is, since the main transport device sequentially transports a plurality of types of articles produced in the production facility, the articles produced in the production facility can be loaded on the mounting body for each product type. become.
In the production facility, since the number of articles to be produced is changed depending on the degree of sales, there is a difference in the frequency of articles conveyed by the main conveying device. Even in this case, efficient loading is possible. The cost can be reduced while the work can be performed, which is useful as a loading facility used for production facilities.

A fourth characteristic configuration of the loading facility according to the present invention includes a plurality of loading portions for mounting each of the mounting bodies arranged for each type of the article, and the above-described mounting body on which the article is loaded. Is provided between the loading section and the self, and a traveling carriage capable of traveling in a state in which the article is loaded and is capable of traveling in a state where the article is loaded, and a traveling path of the transportation carriage, It is comprised so that it may pass through all the said loading parts.

That is, when an article is loaded on the loading body placed on the loading section, the transport cart travels to the loading section, and the loading body is loaded with the loading body. It is possible to travel in a state where the received mounting body is held and transport it to an unloading location or the like.
Since the transport carriage can travel to all of the plurality of loading sections, loading can be performed without providing a conveyor or the like for delivering the loading body on which the article is loaded to the transport carriage. It is possible to directly receive the mounting body on which the article is loaded from the section.
Therefore, the number of conveyors and the like can be reduced to reduce the cost and simplify the configuration, so that the mounting body loaded with the articles can be transported to the unloading location.
