It is used for systems that can perform high-efficiency, high-speed, and accurate operations: it belongs to the technical field of conveyor equipment construction.

<Summary of the gist> The invention of this application can be used, for example, in the pre-processing of packaged products for each type in the backyard of a supermarket to the sorting of set quantities for shipping, and in the pre-processing in various production factories. The invention relates to a conveyor device that consists of a single line installed from the parts manufacturing section to the next stage's unloading section. Arranged in the direction, the bell between! -] Conveyor A7, roller conveyor, string conveyor 7
A predetermined number of unit conveyors of corresponding lengths are connected in series and rotated by one drive motor.
At least one of the predetermined number of unit conveyors a is linked to an actuator such as an air motor to rotate the unit conveyor in a horizontal plane, and in addition, to rotate the unit conveyor on a downward slope in front. The sorting system is designed so that it can be tilted freely at an angle of inclination such as 1, etc., and can be freely connected to the conveyor to the next stage or shoes 1 to 1. This invention relates to a frame device.

<Prior Art> As is well known, supermarkets and the like handle a wide variety of products in large quantities and small quantities, and in order to sell them, they must be sorted by type of product or by a set number for each store. The sorting process must be carried out under strict control, such as storing in a container and transporting it by truck, etc.; It is essential that various types of parts in large quantities and small quantities are conveyed and supplied to each production line, and in order to improve these sorting operations and management efficiency, various parts are technology has been developed,
In recent years, host computers, terminal operating devices, and the like have been used to perform controlled operations with considerably high efficiency.

For example, in the backyard of a supermarket, etc.
Who? When sorting various types of products and small quantity products, for example, the sorting shown in Figure 7 is performed using a system 1 using a stacking section 2 separated by a set distance from the preceding processing section.
From the bell 1 to the conveyor 4, which has a fairly long journey from the
For predetermined sorting, river belt conveyors and chutes 5.5 are branched and connected, and photoelectric detection sensors 6.6 are installed at the connection points. Detecting the passing products and sorting based on the detection signal is carried out by arm 7.
7... via an actuator 8 such as an air cylinder, or by providing a divider 7', predetermined products are transferred to the sorting bell 1 to the conveyor or the chute 5.5... The products are sorted and stored in containers (not shown) that are attached to the tip of each container, and transported to the next stage in a predetermined manner. The detection sensors 6, 6, . . . are used for detection by a computer (not shown).

This kind of sorting system was basically the same even in machine production factories.

<Problem to be solved by the invention> However, in the conventional sorting system, the installation length of the basic belt conveyor 4 is extremely long, and furthermore, the accumulation section 2 at the base is located in the manufacturing section or the processing section. Because it is located far away from the main building, it occupies a fairly large area when installed in a limited area, making it difficult to connect with peripheral equipment and equipment, resulting in a lot of wasted time and space. It has the disadvantage that it is difficult to utilize it effectively, and it also unavoidably requires the minimum number of workers, and because the equipment is large-scale, there are problems such as cumbersome maintenance and maintenance, and there are problems such as capital investment. This has the disadvantage of resulting in higher costs, and the disadvantage is that the work efficiency is poor due to the connection of belts, etc., which impedes high-speed sorting, and the resulting sorting is either a mistake or can be avoided. However, there was also a disadvantage in terms of safety, as it was a negative point in terms of safety.

Therefore, there was the disadvantage that it could not be directly connected to the production line, and thorough inventory management could not be carried out.

As shown in Fig. 5, it requires a large space in the horizontal direction, such as a large-scale conveyor facility, but the ancillary facilities and equipment such as detection sensors installed at various locations are simple. There was a problem that it could not be done properly, and maintenance, inspection, maintenance management, etc. were also troublesome.

Furthermore, in order to increase or decrease the sorting process, it is not possible to easily change the setup due to the connection with the main conveyor, and once the equipment is put into operation, it is difficult to change the layout of the equipment. There was also the disadvantage of not being able to do it.

<Object of the invention> The object of the invention of this application is to solve the problems of sorting various old and new products in the backyard of a supermarket based on the above-mentioned prior art and sorting parts in a machine manufacturing production factory. The technical issues to be solved are to make effective use of limited space, make it easy to rearrange equipment and change the layout, make it easy to allocate personnel, speed up sorting, and avoid errors in sorting. It can be connected directly to the production line, facilitates inventory management, allows safe and highly efficient work, and allows easy and smooth maintenance, making it useful for transportation technology applications in various manufacturing and distribution industries. We aim to provide an excellent sorting conveyor system.

In order to solve the above-mentioned problems, the structure of the invention of this application, which is based on the scope of the above-mentioned patent claims in accordance with the above-mentioned object, is to directly convey the belt conveyor from the production department of the previous stage, etc. Products and parts are conveyed to a conveyor device for sorting, and the sorting is carried out in a straight line in the longitudinal direction, or
A relatively short belt-type or roller-type string type unit that runs along the length of the frame arranged through a predetermined curve!
A set number of conveyors are installed in series in a set number of hour-shaped or drum-shaped rolls and are connected to each other along the forward direction. It is operated to continuously advance the products and parts that have been brought in, and at the unloading section to the next stage such as a predetermined part of the frame, a chute is used to chute the container set in the predetermined part. The unit conveyor corresponding to the base of each chute detects the type of the product using a photoelectric or other product detection sensor installed in its frame, and inputs the information to a computer. The product is moved forward by the unit conveyor by operating an actuator such as an air motor to rotate the unit conveyor horizontally at a set angle, or by tilting it at a set angle such as a downward slope. The sorting is transferred from the sending state to shoe 1~ with a baton touch,
When carried into a container, the number of products transferred from the unit conveyor is detected by the count detection sensor (the number is input into the computer, and when the set number is reached, the actuator is activated to rotate and tilt the unit conveyor and return it to its original position). , the goods to be brought in again are continuously transported forward by passing through the restored unit conveyor as well,
In this way, the sorting conveyor system effectively utilizes the space without equipping a divider or sorting arm, and the products carried to the sorting C conveyor system are reliably divided into the set number of products for each product type. Products are sorted (carried in) into containers, etc., and the products carried into the containers, etc. are carried to the next stage in a predetermined manner, and when the number of stages increases or decreases, the unit conveyor that has an integral actuator is increased or decreased for sorting. 1. All you need to do is increase or decrease the number of chutes and containers, which will make effective use of space, reduce costs, enable high-speed sorting, and allow for safe maintenance, inspection, etc. Technical measures have been taken to facilitate maintenance and efficient sorting.
