Description

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology belongs to the structural technology field of mass sorting devices that sort and deliver products to a large number of stores such as those selling food products.

<Summary of the gist> The invention of this application is that when sorting packaged products etc. to each store, each packaged product after planting is conveyed by the main transport conveyor in the vertical direction. This invention relates to a sorting device that is provided with a sorting conveyor that delivers items separately, and is provided with a sensor that transmits a control signal to a drive device that switches and controls the left and right reciprocating movement of each sorting conveyor. The main conveyor in the vertical direction that conveys products such as packaged products to and from the store is composed of a plurality of roller conveyors, and a sorting belt conveyor is provided between each roller conveyor and intersecting with the roller conveyor. On the outer surface of the belt conveyor, hook-shaped sorting ribs and sub-ribs with reduced height are protruded in front and back of the hook-like sorting ribs, and furthermore, sensors such as rotary sensors are installed to control the drive device that reciprocates the sorting belt conveyor. This invention relates to a sorting device provided on the end side of the sorting belt conveyor.

<Prior Art> As is well known, as consumer life has become extremely fluid, products such as packaged products handled in the secondary market have come to be handled in large quantities, in small quantities, and in a wide variety of types. Increasingly, each store carries a wide variety of products and a large quantity of products.

Therefore, at wholesale centers, etc., it is necessary to sort and deliver a large variety of products in predetermined quantities to each affiliated store. It has become essential to sort products according to orders for each destination store.

For each product, for example, for a belt conveyor, etc., for one type of packaged product, information such as the product name, date of manufacture, unit price, total weight, total price, and the name of the manufacturing company in the handling series are recorded. Therefore, printed labels with so-called prices are pasted on them, and when sorting a large number of products with various prices at a center, the sorting workers form groups of several dozen people. Currently, each product is manually sorted by store by destination while checking order slips and shipping slips.

For each product, such as packaged products, pricing for each product type is highly automated and labeling work is done quickly on the conveyance line, but it is difficult to concentrate many types of products in one place. Collect them,
As mentioned above, the manual sorting of each delivery destination store by a group of several dozen people has become an extremely serious problem for the distribution system in terms of work efficiency.

<Problems that the invention aims to solve> Namely, firstly, there is the inconvenience that sorting errors are unavoidably likely to occur because it is done manually, and calculations for the centers at each store after delivery do not match, and also the display There is a drawback that it may cause problems with the product, and it also has the disadvantage of having to carry out sorting and shipping two or three times between the store and the center to return and reorganize the product, which is a cumbersome process. It was hot.

In addition, since the sorting process is performed manually, there is a problem that the efficiency of the sorting work is low, resulting in a disadvantage that costs such as labor costs are high.

Furthermore, since it is done manually, the frequency of manual handling for one product is high, and therefore,
Some of the products also had negative points such as not being hygienic.

Furthermore, as mentioned above, even though the pricing work in the first stage is mechanized and automated and can be performed at high speed, the efficiency of the later sorting stage is poor, resulting in a decrease in the efficiency of the line as a whole. Netsuku was hot.

Moreover, since the process is performed manually, a large amount of space is required for staffing, etc., which hinders the effective use of equipment, which is an undesirable problem.

<Purpose of the invention> The purpose of the invention of this application is to solve the problem of sorting products to be delivered to each store at a center based on the above-mentioned prior art, and to solve the problem of sorting products by number, type, and number of products. Regardless of the number of items to be delivered to the destination, etc., the sorting work can be done labor-savingly and quickly by automating the previous step of pricing work, etc., even if it occupies an extremely limited and small area. Regardless of the situation, sorting is carried out with high efficiency, multiple products can be sorted in parallel, and data can be exchanged in an online system to ensure accurate work. The purpose of the present invention is to provide an excellent sorting device that is useful for product handling operations in distribution operations.

<Means/effects for solving the problem> In accordance with the above-mentioned purpose, the structure of the invention of this application, which has the gist of the claims for utility model registration as mentioned above, is to solve the above-mentioned problem by changing the store name and Products such as packaged products, on which predetermined items such as date, unit price, weight, and total weight are printed and priced, are conveyed by the conveyor in the previous stage and arranged in series in multiple vertical directions on the sorting line. When the product is fed to the unit of each sorting device and carried into the main vertical conveyor of each unit of the sorting device, a photoelectric detection device installed on the side detects the main conveyance of the product in the vertical direction. After detecting the number and type and confirming that the product is from the sorting store, which was input into the computer in advance using the operating device installed on the side of each sorting device unit, the data is exchanged with the computer. The computer rotates the drive motor of the sorting belt conveyor of the sorting device towards the set sorting store side, and is installed between the vertical main conveyance conveyors in a direction that intersects with each vertical main conveyance conveyor in a posture that does not interfere with the main conveyance conveyor. The sorting belt conveyor is rotated toward the store, and the products that are conveyed to the vertical main conveyor, which is constantly rotating in the vertical main conveyance direction, are transferred to the sorting belt conveyor. is first floated by the sub-rib of the sorting rib provided in the front in the longitudinal direction of the side of the sorting rib, and then moved laterally by the sorting rib,
The sorting guide roller conveyor connected to the side of the sorting belt conveyor continuously sorts and stores the goods at the store, and the goods are packed and delivered to the store. When the sorting rib reaches the end of the main conveyor in the vertical direction, a rotary sensor connected to the drive shaft causes the drive motor to suddenly stop via the computer. By detecting the data to be sorted into the store concerned about each product that is continuously carried in from the main transport conveyor in the vertical direction, the products are sequentially transferred to the sorting guide roller conveyor installed on the left and right of the unit of each sorting device. After sorting, each product that has not been sorted is sequentially conveyed backwards through the units of the sorting device by a main transport conveyor in the vertical direction.
By inputting the sorted products of the store in advance through the operation panel installed on the side of the sorting guide roller conveyor of each sorting device unit, labor-saving,
In addition, technical measures have been taken to ensure that all products for each store are automatically sorted.

<Example> Next, an example of the invention of this application will be described below based on the drawings.

In FIG. 1, a mode is shown in which the unit of the sorting device 1 on the nearest side shown in FIG. 2 is connected to a main conveyor 3 having a pricing device 2.

As shown in FIG. 1, the sorting device 1 has conveyors disposed on the top of a T-shaped frame 5 when viewed from above, and drive rollers 6 and 6 on the base side thereof.
Driven roller 7 and idle rollers 8, 8...
A take-in conveyor 9 stretched over the main conveyor 9 is provided to mainly convey the products 11 in the vertical direction, and is connected to the main conveyor 3.

Although the intake conveyor 9 is a flat belt in the illustrated embodiment, it is of course possible to use a roller conveyor within the scope of design changes.

In front of the intake conveyor 9, a plurality of main transport conveyors 10, 10, . Thus, the packaged products 11, which are constantly rotated and conveyed in the circumferential direction together with the intake conveyor 9, can be primarily conveyed in the vertical direction.

In addition, the main transport conveyors 10, 10 in the vertical direction...
At both ends of the , each of a plurality of stores (in the first embodiment, stores A and B Guide roller conveyors 12, 12, .

Therefore, each of the intake conveyor 9, the vertical main conveyor 10, and the guide roller conveyor 12 of the conveyor all rotate synchronously at all times.
It is designed to rotate.

As shown in FIG. 2, the units of the sorting device 1 are standardized as described above, and a set number of units can be connected in series. A connection mode of a combination of sorting for B and then sorting for stores C and D is shown in the subsequent stage.

A scanner and a photoelectric sensor 13 are installed on both sides of the front end of the mounting conveyor 9 to read the barcode of the pricing label affixed to the packaged product 11, and a photoelectric sensor 13 is installed near the tip of the guide roller conveyor 12. are each provided with an operation panel 14 equipped with a numeric keypad, a digital counter, etc., which are electrically connected to a computer 15 as shown in FIG.
Packaged product 1 mainly transported in the vertical direction by
In addition to checking the number of 1's, the type of the packaged product 11 is detected by reading the bar code, and the data is fed back to the computer 15 for sorting management.

Note that the photoelectric sensor 13 is not provided with a scanner, and only the arrival of the product 11 is confirmed, and the confirmation signal is fed back to the computer 15 and is sent to the A side according to a program input in advance to the computer 15. It is also possible to perform sorting by switching to the store side on the B side, and this is a design matter related to software.

The set number of longitudinal main transport conveyors 10, 10... are parallel to each longitudinal main transport conveyor 10, that is, intersect with the longitudinal main transport direction. As shown in FIG. 3, endless belt type toothed belt sorting belt conveyors 16, 16... are arranged, and guide roller conveyors 12, 12... are connected to both outer ends thereof. As will be described later, it is possible to freely switch between predetermined left and right reciprocating rotations.

Each of the sorting belt conveyors 16 is configured to rotate in synchronization, but the constant rotation of the intake conveyor 9, the vertical main conveyor 10, the guide roller conveyors 12, 12... Intermittent reciprocating rotation is also possible.

Therefore, to explain each drive mechanism in detail, each of the main transport conveyors 10 in the vertical direction has a ring-shaped notch 17 with a semicircular cross section formed at one end thereof, as shown in FIG. As shown in FIG. A round belt 19 is stretched across the belts at a 90° angle.

As shown in FIG. 4, a belt 23 is stretched between a pulley 20 provided at one end of the drive roll 18 and a pulley 22 of a motor 21 with a speed reducer provided on the frame 5. The rotational force of the motor 21 is transmitted to the main conveyor 1 in each longitudinal direction via the drive roll 18, each round belt 19, and the notch 17.
As will be described later, the conveyor 9 is constantly rotated in synchronization with the direction of rotation of the taking-in conveyor 9, and the packaged products 11
The baton is touched and continuously fed forward.

Furthermore, a pair of gears 24 are fixedly installed at the front end of the drive roll 18, as shown in FIG. Guide roller conveyors 12, 12... provided perpendicularly to the longitudinal main transport direction from both sides of each longitudinal main transport conveyor 10
Sprocket 27 provided on the most proximal end of
As shown in FIGS. 11 and 12, chains 28, 28 are tensioned and engaged between the guide roller conveyors 12, 12, . . . to rotate at the same speed. The side sorting guide roller conveyors 12, 12... all the guide roller conveyors 12, 12, . The above-mentioned mechanism allows the intake conveyor 9 and the main transport conveyor 10 in the vertical direction to be connected to each other, and
The guide roller conveyor 12 is always rotated synchronously by a motor 21.

Further, the other drive motor 30 provided for the frame 5 is equipped with a reducer 31 as shown in FIGS.
A well-known electromagnetic brake 32 is provided at one end of a drive sprocket rotation shaft 36 of one of the sprockets 34 and 35 engaged with a pulley 33 provided on its output shaft and both ends of each sorting belt conveyor 16. A belt 38 is stretched between a pulley 37 provided at
The drive motor 3 is set so that 0 rotates once.
The power generated by the reciprocating rotation of 0 is transmitted to the sorting belt conveyors 16, 16, . . . so that the power can be reciprocated.

In this case, the half rotation of the sorting belt conveyor 16 means that the sorting ribs 39 protruding from the outer plane of the sorting belt conveyor 16, as shown in detail in FIG.
The separating rib 39 is configured to perform a reciprocating movement from one outer position of the driving sprocket 34 or the driven sprocket 35 to the other outer position, and the sorting rib 39 is shown in detail in FIG. As shown, the main rib 40 and the sub-ribs 41, 42, which protrude from a large amount to a small amount, are formed on the outer surface of the rear side of the sorting conveyor 16 on the opposite side to the toothed side at a predetermined interval, a height difference, and the same pitch. The main rib 40 is integrally planted, and the main rib 40 is connected to the main conveyor 12 in the vertical direction.
It has a hook function to sort the packaged products 11 conveyed by the left and right guide roller conveyors 12, 12, . The two sub-ribs 41 and 42 slightly float the packaged product 11 being transported forward by each vertical main transport conveyor 10 with respect to each vertical main transport conveyor 10, thereby reducing the transport force of main transport in the vertical direction. It is designed to work in such a way.

In order to operate the sorting belt conveyor 16 to reciprocate by half a revolution, a control signal is transmitted by the rotary sensor 43 provided on the pulley 33 of the drive motor 30, as shown in FIG. , the rotary sensor 43 is connected to the pulley 3 of the drive motor 30.
A disc-shaped slit cam 4 is provided integrally with 3 and has a slit 44 cut out in a part of its circumference.
The photoelectric sensor 46 is provided on the frame 5 and the disc-shaped slit cam 45 in a U-shape, and as shown in FIG. When the light passes through the sensor 46, a detection signal is sent to the computer 15 and the drive motor 3
The electromagnetic brake 32 of No. 0 operates to immediately stop the drive motor 30 suddenly, thereby causing the sorting belt conveyor 16 to make a half turn and stop.
The sorting rib 39 moves to the outside of the sprocket 4 to move the packaged product 11, and when the drive motor 30 is moved back by the computer 15, the sorting rib 39 moves to the outside of the drive sprocket 34 to the driven sprocket 35 side, or Similarly, the separation rib 39 on the other side is controlled so as to be able to move half a revolution from the driven sprocket 35 to the drive sprocket 34 side.

In the above configuration, as shown in FIG. 2, sorting guide roller conveyors 12, 12, . . . are provided on the left and right sides of units 1, 1, . When a worker enters the sorted products 11 by operating a numeric keypad or the like for each product code in accordance with the sorting slip and order form while going around the operation panel 14 provided on each side of the As shown in FIG. 14, the computer 15 receives the sorting input signal, determines a setting program, and sets the sorting order to the left and right of each sorting device unit 1 or to each unit 1 of all sorting lines. Determine each time.

Then, by operating the drive motor 21 of each unit 1, the drive roller 18 is rotated via the belt 23, and the main conveyor 10 in the longitudinal direction is rotated in the forward direction via the round belts 19, 19... At the same time, the intake conveyor 9 is rotated forward, and the left and right sorting guide roller conveyors 1 are
2, 12, . . . are simultaneously rotated in synchronization as described above.

Therefore, in the sorting line, there is a forward direction between the first main conveyor 3 and the final return conveyor 4, and the left and right sorting guide roller conveyors 12, 12, . . . of the sorting device 1 of each unit.
rotate in unison.

Therefore, one or more branched pricing devices 2 are used to determine the various packaged products 11 such as product name, store name, store name, date, unit price, weight, total weight, etc. When predetermined items are printed, barcodes are attached, and conveyed from the main conveyor 3 in one flow direction, that is, the main conveyance direction in the vertical direction, the various packaged products 11 are serially conveyed from the main conveyor 3. They are successively carried into units 1, 1, . . . of each connected sorting device.

Incidentally, the intervals between the packaged products 11 on the main conveyor 3 are adjusted in advance to a predetermined pitch so that each packaged product 11 is fed at a pitch that allows the next stage of sorting work to be carried out most efficiently.

Therefore, as shown in FIG. 1, the first packaged product 11 is carried into the take-in conveyor 9 of the sorting device 1 of the first unit in the main conveyance direction in the vertical direction, and there, the photoelectric detection device 13 of the scanner is activated. The system checks the packaged product 11 brought in, feeds back the counter signal to the computer 15, and reads the barcode to determine what type of packaged product 11 it is.
By similarly feeding back the confirmation signal to the computer 15, the computer 15 sorts to the left or right sorting guide roller 12 side of which sorting device 1 according to the predetermined software program as described above. and sends an activation signal to the sorting drive motor 30.

Therefore, whether the computer 15 outputs a forward or reverse rotation signal for the drive motor 30 to indicate which sorting line of which sorting device 1 is to be sorted is determined in advance from each of the two sorting sides of each sorting device 1. This is uniquely determined by the input program that follows the shipping slips and order slips for each store that are entered into the operation panel 14 of .

That is, when the forward rotation and reverse rotation of the sorting drive motor 30 are sequentially switched, for example,
The time lag between the sudden stop and start-up caused by the electromagnetic brake 32 is large, which affects work efficiency.
Furthermore, if the first, second, and third sorting devices 1 are used to completely sort packaged products from side to side in order, each unit in the second, third, and subsequent stages will be separated. Since the working conditions differ greatly depending on the sorting combination, such as the waiting time of the sorting equipment 1 being longer, the most efficient sorting for the entire sorting line is performed on each sorting equipment 1 by inputting the sorting information for each store on that day. The computer 15 takes into consideration the efficiency of the combination of each unit.
The program has been entered in advance.

Therefore, in accordance with the above-mentioned program, the computer 15 transmits drive signals for forward and reverse rotation of the sorting drive motor 30 to each of the serially connected sorting device units 1, 1.

Therefore, to the right of any one sorting device 1,
To explain in order the case of sorting the packaged products 11 to the left and the case of free pass to the next stage or the next next stage sorting device 1 without sorting, in Fig. 1, from the intake conveyor 9 The above-mentioned computer 1
According to the program of 5, the packaged product 11
Scan the product type using its barcode.
, the detection signal is sent to computer 1.
5, the computer 15 outputs a signal for normal rotation or reverse rotation to the drive motor 30 of the sorting device 1. For example, in the case of normal rotation, the sorting ribs 39, 39 of the sorting belt conveyor 16 are fed back to the sorting belt conveyor 16.
are the driving sprocket 34 and the driven sprocket 35.
When the drive motor 30 rotates normally, the pulley 33 and the pulley 3
7. By causing all the sprockets 34, 34 to rotate in the normal direction by the rotating shaft 36 via the belt 38, all the sorting belt conveyors 16 are synchronously rotated in the normal direction as shown in FIG. Therefore, the main transport conveyors 10 run in the same phase from the driven sprocket 35 side to the driving sprocket 34 side at right angles to the vertical main transport direction, and run at right angles to the main vertical transport direction. As shown in Figure 4, the front plane of the sorting belt conveyor 16 is lower than the level of the main conveyor belt 10 in each longitudinal direction, but the sorting ribs 39 protrude above the level of the main conveyor belt 10 in each longitudinal direction. Moreover, sub rib 4
1 and 42 are raised sequentially in the direction of travel, so that the bottom surface of the packaged product 11 is slightly lifted and floated above the main transport conveyor 10 in the vertical direction. The conveyance force is weakened and the conveyance is forcibly transferred to the right side of the guide roller conveyor 12, 12, . . . by the hook action.

When approaching each guide roller conveyor 12, 12, as described above, the guide roller conveyor 12, 12... also takes in the conveyor 9, and
Since the main transport conveyor 10 in the vertical direction is always in operation, the transport direction is changed by 90° and the paper is forcibly sorted towards the guide roller conveyors 12, 12, . . ., in the A direction, and When the sorting belt conveyor 16 rotates and the sorting rib 39 moves half a turn from the outside of the flow sprocket 35 to the outside of the drive sprocket 34 to sort the packaged products 11 as described above, the sorting belt conveyor 16 rotates and the sorting rib 39 moves half a circle from the outside of the flow sprocket 35 to the outside of the drive sprocket 34 to sort the packaged products 11 as described above. Since the slit 44 of the disc-shaped slit cam 45 of the rotary sensor 43 provided in The computer 15 causes the drive motor 30 to suddenly stop by using the operation signal of the electromagnetic brake 32. Therefore, the sorting belt conveyor 16 is suddenly stopped by the drive system, and the sorting rib 39 is moved to the outside of the drive sprocket 34. The sorting rib 39 on the other side is positioned outside the driven sprocket 35 and is placed in a position ready for the next sorting operation.

In this case, the guide roller conveyor 12 on the A side receives the hook action from the sorting rib 39.
The packaged product 11 transferred to the side continues to be fed by the constantly rotating guide roller conveyor 12, and since the guide roller conveyor 12 is tilted at a set angle as shown in the figure, the component force of the tilt is The materials are naturally fed to the storage area at the tip, stocked appropriately, and packed into a transportation box in a predetermined manner.

Then, the next packaged product 11 is carried from the main conveyor 3 to the take-in conveyor 9 and detected by the photoelectric detection device 13, and the detection signal is fed back to the computer 15 in the same way as in the above process. In addition to detecting the count of the product, the time difference between the count and the count of the packaged product 11 fed in the previous feeding is also detected, and if it is shorter than the minimum required time interval for the sorting operation of the sorting device 1, the main conveyor 3
The feeding interval of the packaged product 11 is appropriately controlled so as to lengthen the feeding interval.

In addition, if the length is long, a control signal is issued to speed up the feeding so that the time interval is short enough to achieve the highest efficiency.

As a matter of course, during the rotation and stop of the sorting belt conveyor 16, the intake conveyor 9 and the main transport conveyor 1 in the vertical direction are
0, and guide roller conveyors 12, 12...
is constantly rotating.

Then, packaged product 1 is brought in next.
1 to a store on the opposite belt conveyor side, the scanner 13 is programmed to determine that the packaged product 11 is to be sorted to a store on the belt conveyor side of the sorting device 1. The packaged product 11
After detecting the set time lag, the computer 15 issues a reverse rotation command signal to the drive motor 30 via a timer, thereby controlling the pulleys 33, 37,
Through the reverse movement of the belt 38, the sorting belt conveyor 16 is reversed, and the outer sorting rib 39 of the drive sprocket 34, which has been waiting as described above, rotates in the opposite direction to the above-mentioned direction, and the main conveyor 16 is rotated in the vertical direction from the intake conveyor 9. The sorting belt conveyor 39 uses its sub-ribs 41 and 42 from the opposite direction to handle the packaged products 11 carried onto the conveyor 10 from the lower part of the bottom of the main conveyor 10 in the vertical direction. Raise the main rib 40
The conveyance direction is forcibly shifted by 90 degrees to the store sorting direction of the belt conveyor at a right angle to the main conveyance direction in the vertical direction, and the conveyance direction is transferred by 90 degrees to the guide roller conveyor 12, 12. The baton is forcibly touched, and the inclination is used to sort the belt conveyor to the store.

In this way, each packaged product 11 carried in from the main conveyor 3 according to the commands of the computer 15 according to the above-mentioned program is sorted into each store according to its product name and program.
As mentioned above, in order to perform the most efficient sorting on all sorting lines, the packaged products 11 are sent to the next or next stage sorting device 1 and are sorted there. In this case, in order to prevent the sorting device 1 at the front end from performing sorting, the computer 15 sends a sorting signal, that is, a command for forward or reverse rotation to the sorting drive motor 30 of the sorting device 1. Naturally, if the signal is not transmitted, the drive motor 30 does not start and remains stopped, and therefore the packaged products 11 carried from the intake conveyor 9 to the main transport conveyor in the vertical direction are not sorted. Because the belt conveyor 16 does not rotate,
As mentioned above, the planes of the sorting ribs 39, 39 are lower than the level of the main conveyor 10 in the vertical direction, so the upper surface of the main conveyor 10 in the vertical direction, which is constantly rotating, is forced to rotate forward. The sorting devices 1, 1, 1 in between are carried out and passed to the take-in conveyor 9 of the next stage sorting device 1, and then subjected to the sorting action of the sorting device 1 at the set location.
...In this way, you will be able to freely pass through the gap.

Then, the packaged products 11 that are not finally subjected to the sorting action or that are incorrectly fed pass through all the sorting devices 1, 1... and are returned from the return conveyor 4 at the final stage, or , they are stored as appropriate and sent to the next stage of disposal.

In this way, the various types of packaged products 11, 11 carried in from the main conveyor 3 can be sorted in the most efficient way, regardless of their quantity or whether there are many or few sorting stores. The packaged products 11 that have been sorted into stock areas for each store are appropriately packed into transport boxes and transported by truck as described above.

Incidentally, it goes without saying that the embodiment of the invention of this application is not limited to the above-mentioned embodiment. For example, regarding the intake conveyor 9, not only a flat belt but also a flat belt,
A roller conveyor may also be used, and the main longitudinal conveyor in each sorting device may be a tapered conveyor with a wider cross-sectional area on one side, instead of mutually parallel roller conveyors with equal longitudinal cross-sectional areas. A roller conveyor may be used to make the sorting line meander, or a combination of these may be used, and a scraper may also be set in the middle of the intake conveyor to remove misdelivered products from the belt conveyor. Various aspects can be adopted, such as providing a.

<Effects of the invention> As described above, according to the invention of this application, while products such as various packaged products are sent after the predetermined work has been completed by the previous work device such as the pricing device, With two sorting devices, products can be sorted freely for each store on the left and right, and,
By connecting the desired number of sorting devices in series, the sorting devices are standardized to be used as a unit. Regardless of the number of sorting stores or the number of types and quantities of products to be sorted, the excellent effect of being able to carry out the sorting work most efficiently and accurately with labor saving can be achieved.

In addition, since the sorting equipment is standardized as mentioned above, it is possible to design one unit so that the number of stages of multiple units can be connected as desired. Because it only needs to be set to the base, no special mechanical connection work is required.
Therefore, an excellent effect is achieved in that the length of the sorting line can be freely and easily changed on site.

In addition, since each sorting device can exchange data with a computer, shipping slips and other information can be accessed using the numeric keypad on the operation panel located on the side of the guide roller conveyor for sorting by store, which is installed on the left and right of each sorting device. If input is made using an order slip, etc., it has the excellent effect of performing the most efficient sorting work according to the best sorting program, regardless of the size of the products sent to each unit, or regardless of the number of products. It is played.

Therefore, in the sorting device when used as each unit, a sorting belt conveyor having sorting ribs in a direction intersecting the main vertical conveying direction is arranged between the main conveying conveyor in the vertical direction. Since the reciprocating movement is made possible by a drive device that can freely switch reciprocating motion using a sensor connected to the computer that is the control device, it is possible to sort products according to the program while the main conveyor in the vertical direction is constantly operating. This is an excellent effect.

In addition, since a sensor such as a rotary sensor is installed at the end of the sorting belt conveyor, it becomes a kind of mechanical detection, which reduces malfunctions and completes the sorting of products from left to right by the sorting belt conveyor. Since the drive motor can be stopped at the point where the sorting operation is performed more accurately, the effect is achieved that the sorting operation is performed more accurately.

In addition, the sorting rib provided on the sorting belt conveyor has a plurality of short sub-ribs relative to the main rib with the largest protrusion, so that the sorting ribs are fed by the vertical main conveyor. When sorting, the product can be floated lightly and the main ribs can reliably provide a sorting effect, which also has the excellent effect of making sorting easier.
