The turnconveyor 48 is then driven to deliver a package 4 on the central conveyor 3 onto the classifying conveyor 21.

Description

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology is in the field of system technology for devices used in cases such as sorting various packaged products for each store in a back center of a supermarket, etc. belongs to

Summary of the Purpose> The invention of this application is a guide frame that is erected at the back center of the supermarket, etc. at the base when sorting and shipping various packaged products to each of a predetermined number of stores. A line that runs along the
Alternatively, predetermined types of packaged products are intensively loaded and conveyed over time via a switching conveyor, etc. connected from the previous stage to a central belt conveyor installed in multiple upper and lower stages, and then transferred to a guide frame from above the central belt conveyor. A plurality of sorting devices such as roller conveyors arranged in close proximity to each other on both sides or the minus side is an invention relating to a sorting device in which the sorting is distributed according to a preset number on the conveyor, and in particular, the invention relates to a device for sorting devices such as a roller conveyor installed on both sides or on the negative side. Roller conveyors, etc., installed perpendicular to a guide frame on both sides at set intervals, are used to sort and distribute products to the conveyor, especially on the rails provided on the guide frame. A casing supported by a plurality of support rollers and a drive roller is movable forward and backward, and the drive roller is driven forward and backward through a drive device mounted on the casing, and the casing is pivoted horizontally on the casing. The central conveyor belt is wound around a pair of upper and lower rollers in a double fold, and the sorting is carried out relative to the central conveyor belt through a position sensing switch such as a proximity switch and a sensor switch at points corresponding to the long conveyor. The packaged products are sorted through a turn conveyor that stops, extends from the front side of the casing in both left and right directions, and is rotatable in at least one direction, so that the packaged products are distributed and sorted without changing the posture of the conveyor. This high-speed sorting device is an invention related to a device.

<Prior Art> As is well known, in supermarkets and the like, various packaged products such as meat and vegetable foods are delivered to each store and sold. In addition to backing and pricing various products, it is also necessary to accurately deliver packaged products to each store according to the number of orders received. To do this, it is necessary to accurately sort each type of packaged product to each store according to the order. Must.

Therefore, in many cases, the back center etc.
The device and the weighing and pricing device are connected by a conveyor, and the packaging work of the product and the weighing and pricing work of attaching a label with printed product data such as selling price to the package after weighing are completely automated, and the remaining sorting is done. Currently, the work has been completely left to manual labor.

The most common type of work is to place two workers at the packaged product delivery end of the weighing and value marking device.
One person is in charge of supplying containers for storing packaged products for each store to the vicinity of the above-mentioned delivery end and removing the containers filled with products, and the other person is responsible for the work of supplying containers for storing packaged products for each store and removing the containers filled with products.The other person is responsible for the work of supplying containers for storing packaged products for each store and removing the containers filled with products. We are sharing the work of manually filling the empty containers provided.

In this type of work, it is quite difficult to confirm that the destination store has changed since each worker is busy with hand-packing work, so it is unavoidable to store the information in the FFI pricing device. Based on the number of orders received by each store, the device is manually stopped each time the pricing process for the number of orders for one store is completed, and the manual work such as manual packing and container replacement is completed and the worker outputs the output. Means is adopted for starting weighing for the next store in response to a start signal or a set time of a timer.

<Problems to be Solved by the Invention> In this type of embodiment, each device having a continuous processing capacity is used intermittently, so there is a drawback that the capacity of each device is limited to the capacity of manual labor.

On the other hand, another aspect of the non-stop use of each device is that there are two
We connected a directional sorting device, assigned two sets of workers in each direction, and automatically switched the direction of product delivery each time the destination changed, eliminating the need for each device to stop due to changing containers. It is a means.

However, even with this method, the work density of the two groups is not uniform due to an imbalance in the number of orders received by store, resulting in workers being on hand.Furthermore, with a small number of orders, it is not possible to secure time for changing containers, so it is not possible to completely Another drawback was that non-stop operation was not possible.

In either case, automatic processing and sorting using various devices such as packaging, weighing, direct mounting, etc. cannot be completed without the manual work of manually filling the containers with the products. This was considered the biggest bottleneck in rationalizing the distribution field.

In particular, as explained above, it is possible to automate the sorting process, and if a distribution conveyor that can sort the sorted packaged products is installed, each device will be able to run at full capacity, and workers will be able to quickly dispatch vehicles in the order in which they are dispatched. This allows customers to select a store to fill containers.

Due to these circumstances, there has been a strong demand from the industry for a distribution device that can automatically handle sorting, which is the field in which rationalization has been slowest in the distribution industry.

Therefore, to deal with this, the applicant's earlier invention, Japanese Patent Application No. 58-130772, and the subsequent patent application No. 58-130772,
213260'@Invention, etc., packages and priced packaged products that have been processed in the pre-stage processing are conveyed by a certain type to one central belt conveyor, and the products are conveyed in a predetermined direction in the longitudinal direction of the central belt conveyor. When performing a certain sorting on a roller conveyor for each store that is connected to the store, a self-propelled sorting device is installed on the central belt conveyor, and high-speed and efficient sorting is carried out. Technologies to perform this have been developed and are being put into practical use.

This kind of sorting is carried out by using guide rollers 3, 3, and 3. ..., a central belt conveyor 3 serving as a central conveyor is rotatably stretched over a predetermined length, and predetermined types of packaged products 4, 4 processed by predetermined preceding packaging devices and pricing devices are continuously conveyed. A box-shaped casing is supported by support rollers 6.6, drive rollers 6', and guide rails 5 provided on each of the guide frames 1.1. 7 is movable forward and backward, and a chain 10 that engages with a sprocket 9 of a drive mechanism 8 provided at a predetermined position on the upper surface of the chain 10 is attached to a sprocket 1 of a drive roller 6'.

Even if the package moves forward and backward relative to the guide frame 1 at a predetermined speed, there is no effect on the rotation of the central belt conveyor 3 at the predetermined speed, and the package is placed on the central belt conveyor 3 and transported. The product 4 is conveyed at the running speed of the central belt conveyor 3.

As shown in FIG. 10, a pair of frames 16 and 18 are attached to the front part of the casing 7 via a bracket 15, curved by 90" in the lateral direction, with the distance between the two always kept constant. A support roller 18 is pivotally supported on a bracket 17 provided on the frame 16 at the front thereof, and supports the frame 16.16 so as to roll on the rail 5.

A set number of tapered roller conveyors 19, 19, . . . are arranged at predetermined intervals in the pair of frames 16, 16 to form a turn conveyor 20.

The turn conveyor 20 is capable of moving forward and backward along the guide frames 5, 5 which are integral with the casing 17.

The turn conveyor 20 meets the guide frame 1 at right angles to the sorting roller conveyors 23, 23, which are rotatably supported at both ends by the frames 22, 22 of the conveyor 21. It is arranged to be positioned.

A photoelectric sensor 24 is mounted on one side of the frame 16.16 of the turn conveyor 20, and a light receiving sensor 2 is mounted on the other side.
4' is provided to count the number of packaged products 4 transferred from the turn conveyor 20 to the sorting conveyor 21.

In order to drive each tapered roller 19 of the turn conveyor 20, a chain 26 engaged with a sprocket 25' of a drive motor 25 provided near the front side of the casing is connected to a tapered roller provided on the frame 16. 19, and engages with the sprocket 17 provided at the tip of the adjacent taber roller 19. All the taber rollers 19, 19,
The packaged product 4 is synchronously transmitted with rotational force, ascends upwardly from the slit 7' at the rear end of the casing 7, and moves upwardly over the upper roller 13 of the pair of upper and lower rollers 13.14. The sorting is transferred to a tapered roller 19 on the starting end side of the same novel as the upper roller 13 in a baton-touch manner, and the sorting is transferred to the roller conveyor 23 of the conveyor 21.

As shown in FIG. 10, power is supplied to the drive motor 8.25 of the casing 7 by a roller 31.31 that engages with a rail 30 provided parallel to the guide frame 1.

is connected to a control panel 33 to operate the electrical system in a predetermined manner.

In FIG. 11, a proximity switch 34 is provided on the guide frame 1 side to detect the proximity of the conveyor 21 to the conveyor 21, and a corresponding sensor switch 35 is provided on the casing 7 side. When the proximity switch 34 is approached, that is, when the tip of the turn conveyor 20 approaches the base end of the sorting conveyor 21, a brake (not shown) is actuated to stop the sorting device 29, and the central belt conveyor 3 continues to run. The packaged product 4 conveyed by the central belt conveyor 1 is transferred from the central belt conveyor 1 to the turn conveyor 20
The sorted items are transferred to a conveyor 22 via the conveyor 22 so that they can be sorted.

As shown in FIG. 14, the guide frame 2 is sorted by conveyor 2 at predetermined intervals in the length direction.
1.21... are provided in a meeting manner, and the sorting equipment @29 runs at a predetermined high speed from the base end side of the central belt conveyor 3.
However, the turn conveyor 20 at the tip of the turn conveyor 20 is made to face the corresponding sorting conveyor 21, so that the conveyor 21 can sort the packaged products 4 for each store.

<Problem to be solved by the invention> However, the sorting device disclosed in the prior invention of the applicant mentioned above and put into practical use is a device whose actual operation becomes more frequent over time, and which cannot be used in a wide range of fields. As this has progressed, the following problems have started to occur.

That is, the packaged product 4 transported by the central belt conveyor 3 from the previous packaging process or the pricing process is transported by the central belt conveyor 3 at a predetermined speed, and the casing advances at a higher speed than the central belt conveyor 3. When the casings 7 are sorted to predetermined stores according to the program by the turn conveyor 20 at the tip, the casings 7 stop in the position facing the conveyor 21, and the packaged products conveyed by the central belt conveyor 3 are separated into a pair. The rollers 13, 14 are transferred from the upper roller 13 to the turn conveyor 20, and each taber roller 19. ．． 19, and the connecting sort is transferred to the roller conveyor 23 of the conveyor 21, and in the theoretical design, as shown in FIG.
Packaged products 4 that are turned 0° and transported
Although the vertical orientation is changed to horizontal orientation and the horizontal orientation is changed to vertical orientation for conveyance, in reality, packaged products 4 are conveyed from the central belt conveyor 3 via the turn conveyor 20 to the conveyor 21. At the stage of transfer, there are extremely small changes, vibrations and rocking occur, and there is also the effect of the convex surface of the packaged product 4, so the 90° angle is not as per the basic design. It is difficult to change posture,
As shown in FIG. 15, in the process of transferring the pair of upper and lower rollers 13 and 14 from the belt conveyor 3 to the turn conveyor 20, the vertical direction is displaced to the horizontal direction, and the horizontal direction is displaced to the vertical direction. However, the displacement of almost 45°, i.e.
A phenomenon often occurs in which the sorting is transferred to the conveyor 21 by being displaced to a diagonal position, and in extreme cases, as shown in FIG. Each posture package product 4.
A phenomenon in which conveyors 2 and 4 interfere with each other also occurs, and conveyor 2
From 0 to sorting, there was a problem in which a kind of conveyance clogging phenomenon occurred on the conveyor 21.

In such a case, the sorting operation at the tip of the conveyor 21, that is, the bottom end, may interfere with the work of packing containers into boxes, making it difficult to carry out accurate and orderly packing work, or the sensor 24° An inconvenience has arisen in that the counting of packaged products 4 by 24' may also be hindered.

Therefore, in reality, in order to eliminate such inconvenience, sorting is performed by conveyor 2 instead of turn conveyor 20.
A worker is on standby at the meeting point of the guide frame 1 in Figure 1, and when a diagonal posture change jam occurs in the packaged products 4, 4, etc., he or she manually corrects the problem in an orderly manner as shown in Figures 10 and 11. As shown in Fig. 2, it was necessary to carry out the work to change the posture and transfer as designed, and the meaning of labor saving was lost.
This method has the disadvantage of increasing costs, and also has the disadvantage of lowering work efficiency.

In the above-mentioned conventional mode, as shown in Fig. 14,
Since the turn conveyor 20 at the tip of the casing 7 is a roller conveyor that curves 90 inches to one side, the conveyors 21 are assembled and arranged for each store only on one side with respect to the central belt conveyor 3. Therefore, there was an inconvenience in that sorting could only utilize half the capacity of the number of stores, and sorting could not make full use of the site area and space of the plant.

<Object of the Invention> The object of the invention of this application is to provide a central conveyor used for sorting various packaged products to each store at a back center of a supermarket based on the above-mentioned prior art, and to separate a plurality of sorting products branching from the central conveyor. considers the problem of distribution and sorting for conveyors as a technical issue to be solved, and in order to handle a large number of sorting, just one distributing device is installed for one line in which conveyors are arranged around a central conveyor. According to the set program, various products can be distributed reliably and rapidly in order, and there is no problem in conveying the products on the central belt conveyor, which makes equipment investment low and maintenance and inspection easy. Moreover, it is intended to provide an excellent sorting device that is easy to manage and benefits the field of product processing technology application in the distribution industry.

Means/effects for solving the problems> In accordance with the above-mentioned object, the IM of the invention of this application which has the gist of the above-mentioned claims, or in order to solve the above-mentioned problems, the sorting is carried out in one line, or A predetermined number of central belt conveyors for the upper and lower tank stages are installed along a guide frame and run in a predetermined manner, and various products that have been packaged, weighed, and priced in a predetermined manner according to a program are sequentially conveyed onto the upper part of the conveyor belt by a pre-stage switching conveyor, etc. Then, the casing of the distribution device rotates the drive roller by the drive device and moves along the rail from the base side of the guide frame along the rail provided on the guide frame. At that time, the power supply cable for the drive device expands and contracts along the length of the cough guide frame and moves together with the cough guide frame. A central belt conveyor is wrapped around the rollers in a double fold so that it runs freely in turns, and therefore,
The casing is configured to freely move forward and backward relative to the central belt conveyor, and the casing moves faster than the belt conveyor relative to the guide frame, and has turn conveyors integrally provided on both left and right sides at the leading end of the casing. When the dispensing device approaches the conveyor for the first sorting, the brake provided on the casing is activated by a sensing switch such as a proximity switch provided on the guide frame and a sensor switch on the casing. Upon operation, the distribution device stops, and the front end of the turn conveyor meets the guide frame and the first sort provided is in a position connected to the conveyor, where the drive device provided in the casing is activated. The roller conveyor, belt conveyor, etc. of the turn conveyor rotates through the turn conveyor, and the products conveyed on the belt cylinder running against the upper and lower pair of rollers of the stopped distribution device are transferred to the upper roller of the pair of rollers. The receiver is passed from the top of the turn conveyor while maintaining the same posture and is conveyed horizontally on the turn conveyor, and the sorting connected from the tip is made to pass and convey the receiver accurately without disturbance to the conveyor, and the receiver is transferred in a predetermined manner. Once the number of products has been distributed and sorted, the drive device of the device is activated again and the sorting continues to travel forward relative to the set speed, i.e., at a speed higher than that of the traveling belt conveyor; The next sorting device moves to the conveyor section and stops, and performs the same distribution sorting as described above again. After performing distribution sorting on the last distribution conveyor, the distribution device moves to the rail at the set speed. A technical measure has been taken in which the belt conveyor is moved backwards relative to the central belt conveyor and returns to its initial position.

<Example> Next, an example of the invention of this application will be described below based on FIGS. 1 to 9.

Incidentally, parts having the same features as those in FIG. 10 and subsequent figures will be described using the same reference numerals.

In the embodiment shown in FIG. 1, numeral 36 is a plant for sorting by store at a tuck center of a supermarket, etc., and the central belt conveyor 3, 3 has two stages, upper and lower in this embodiment. The packaged product 4 is selectively transferred to the upper and lower central belt conveyor 3.3 by a vertical switching conveyor 38 provided between the pre-processing device 37 such as a device or a pricing device. The control is carried out in a predetermined manner by an operating device 39, and as shown in FIG. There is.

Each of the upper and lower central belt conveyors 3, 3 is stretched between a driving roller 42 and a driven roller 43 in the same way as in the conventional system, rotated at a predetermined speed, and packaged and priced by a pre-processing unit @37. The processed packaged product 4 is transported.

In the invention of this application, as shown in FIG. 1, housings 44, 44, etc. are arranged in the longitudinal direction on both left and right sides of the central belt conveyors 3, 3, and each store For each 70-rack type sorter, roller conveyors 21, 21... are provided in a downward slope type on the outside, and a digital display device 45 for sorting and processing is provided on the upper stage of each housing 44. , is connected to a repeater (not shown), and has a function that allows confirmation checks and manual sorting in the event of a failure of the device, and in the unlikely event that the device is not transported due to some shape etc. The display allows final sorting to be done manually.

In addition, for each sorting, there are packaged products 4 on the bottom of the conveyor 21.
, 4... are packed in a predetermined box in a container 46,
They are loaded onto trucks, etc.

Therefore, as shown in FIG. 1, the central belt conveyor 3
A return conveyor 47 is provided on the upper surface side of the housings 44, 44, .

In the embodiment shown in FIG. 1, the central belt conveyor 3 is arranged in two stages, upper and lower, but it is also possible to have three or more stages, and this is just a matter of design. It is something.

Each central belt conveyor 3 is provided with a sorting device 19' that can freely move forward and backward at a relatively high speed with respect to the conveyor belt of the central belt conveyor. The casing 7 is substantially the same as that of the sorting device of the applicant's earlier invention, and has a pair of upper and lower rollers 13 and 14 at the front with the belt conveyor 3 facing inside from the slit 7'' at the rear end. The central belt conveyor 3 is wound in a double fold, and is placed in front of the front slit 7' so as not to impede the running of the central belt conveyor 3 at a constant speed.
Therefore, the packaged product 4 can be moved freely without any hindrance to the transportation.

The rail 5 provided on the guide frame 1 is supported by a support roller 6 and a drive roller 6' so that it can run freely, and a chain is connected between the sprocket 9 of the upper drive VjL position 8 and the sprocket 11 of the drive roller 6'. 10
This is also the same as the device in the conventional aspect of the applicant's earlier invention in that it is stretched to transmit running power.

Also, the sorting of the guide frame 1 is carried out by conveyors 21, 21...
・A sensor switch 35 is provided on the casing 7 in contrast to the proximity switch 34 as a sensing switch provided a predetermined distance in front of the casing 7 on the conveyor 21.
It is similar to the conventional system that the brake is applied at a predetermined time to stop the conveyor 21 when the conveyor 21 approaches the conveyor 21.
' is provided so that the sorting can count the number of packaged products 4, 4 to be transferred.

In the invention of this application, a bracket 15' is attached to the tip of the casing 7 and intersects the central belt conveyor 3 at right angles, and a belt conveyor 48 as a turn conveyor in the left and right direction is attached to the bracket 15'. It is stretched between a pivotally supported driving roller 49 and a driven roller 50, and conveyors 21 and 21 are used for left and right sorting at both ends.
It is facing the beginning of the road.

Also, on one side of the guide frame 1, as in the conventional case, a rail 40 is provided, and rotating rollers 31, 31, . . . It is stretched and connected to the control panel 33 of the casing 7.

Further, at the top of the tip of the casing 7, another drive device 25' is installed.
is provided to transmit power from the sprocket 251 to the sprocket 21'' of the drive roller 49 of the belt conveyor 48 of the turn conveyor via the chain 26 via a speed reducer.

The braking action by the proximity switch 34 and the sensor switch 35 and the operation for turning the turn conveyor 48 to the left or right are performed according to a preprogrammed program by a computer of a predetermined control device (not shown) by the lead cable 32. It is like that.

Furthermore, the turn conveyor 48 and the central belt conveyor 3
A separation conveyor 3' rotating at a circumferential speed is interposed between the central belt conveyor 3 and the folded portion, so that smooth transition between the two can be achieved.

Therefore, in the sorting device 29', the casing 7 and the turn conveyor 28 move forward and backward in unison, and when the belt conveyor 48 of the turn conveyor approaches the starting end of the conveyor 21 for predetermined sorting, switch 34,
The casing 7 and the turn conveyor 48 are stopped together by the sensor switch 35, and the types of packaged products 4 conveyed by the central belt conveyor 3 and the sorting according to the computer program are controlled so that the left and right rotation of the belt conveyor 48 of the turn conveyor is controlled. As shown in FIG. 5, the packaged product 4 that is controlled and transferred from the central belt conveyor 3 to the belt conveyor 48 of the turn conveyor via the upper 1-knoll roller 13 does not change its attitude in any way; As shown in Fig. 15 of the previous model, the distribution is accurately sorted without the 90° attitude rotation, and therefore, the clogging phenomenon in the diagonal attitude as shown in Fig. 16 does not occur, and it is reliable. The sorted items can be sorted and transferred to the roller conveyor 23 of the conveyor 21.

In the above configuration, at the back center of the supermarket, sorting is done via the timing device of the plant 36 by pressing the start button, empty container groups 46' are returned via the conveyor 47, and sorting for each store is done via the conveyor 21.
At the same time, the switching conveyor 38 is connected to the central belt conveyor 3 on one side of the upper and lower stages, that is, either the upper or lower side, and the predetermined weight is The packaged products 4 with predetermined labels, etc. and prices displayed are transferred from the pre-processing device 37 to the selected central belt conveyor 3 via the switching conveyor 38, where they are transferred to the drive roller 42 and driven by the drive roller 42. The material is conveyed at the running speed and driving speed of the central belt conveyor 3 stretched between rollers 43.

Then, control is performed via the lead cable 32 by a computer of a control device (not shown). The Il current is sorted through the control panel 43 of the device 29' to drive the bag @8.
, and 25', where sprocket 9, chain 10 . The drive roller 6' runs on the rail 5 of the guide frame 1 via the sprocket 11,
The casing 7 supported by the driven rollers 6, 6, . . . advances at a faster speed relative to the central belt conveyor 3, which runs at a predetermined speed.

In the process, the central belt conveyor 3 is folded in half and wound around a pair of upper and lower rollers 13, 14 at the front of the casing 7, and the slits 11' at the front and rear of the casing 7 are wound.

Since it extends from 1r, the casing 7 travels forward at a relatively high speed with respect to the central belt conveyor 3.

However, the packaged product 4 placed on the central belt conveyor 3 and conveyed at a predetermined speed is transported forward at the conveying speed of the central belt conveyor, regardless of the high speed traveling of the casing 7.

Of course, in this case, as described above, the casing 7 and the separation conveyor 3' and the turn conveyor 48, which are provided at the front of the casing 7 through the bracket 15' and extend in both directions, move forward together at a predetermined high speed.

When the turn conveyor 48 approaches the base end of the conveyor 21 for sorting the store specified by the computer, the sensor switch 35 approaches the proximity switch 34 provided on the guide frame 1 and the drive device 8 is activated. When the brake is applied, the store sorting machine with the turn conveyor 48 set at one end thereof is accurately positioned at the base end of the conveyor 21, and the casing 7 is stopped.

Therefore, the command current from the power supply lead cable 32 is controlled by the control H@ via the microcomputer to the drive device 2.
5', the drive roller 49 of the turn conveyor 48 is rotated forward or reverse in a predetermined direction by the sprocket 251, chain 26, and sprocket 27', and the conveyor belt of the turn conveyor 48 is rotated forward or reverse. Therefore, as shown in FIG. 5, the packaged product 4 placed on the running central belt conveyor 3 and conveyed is placed between a pair of upper and lower rollers in the casing 7 of the upwardly inclined central belt conveyor 3. 13. It is smoothly transferred from the upper stage roller 13 of 14 via the separation conveyor 3' to the upper surface of the conveyor belt of the turn conveyor 48 located at the same level, and is immediately placed sideways without any attitude change to the left or right side. The sorted items in the store are transferred from the end to the roller conveyor 23 of the conveyor 21 and fall through gravity, leaving the container 46 waiting at the base end.
are picked and stored in a specified location.

Meanwhile, as shown in FIG.
', the number of transported products 4 to the store that are dropped and transported by gravity is counted.

When the packaged product 4 placed on the central belt conveyor 3 and transported has finished being transported to the store, the drive M position 8 is activated again via the power supply lead cable 32, and the sprocket 9, chain 10, Sprocket 1
The driving Ronilla 6' rotates through the guide frame 1 to integrally move the casing 7 and the turn casing 48 to the guide frame 1.
The upper and lower rollers 1 in the casing 7 of the central belt conveyor 3
3 and 14 in the wrapped state without any problem, the turn conveyor 48 is located close to the base end of the conveyor 21, and the next store sort specified by the computer is close to the base end of the conveyor 21, and the proximity switch 34 of the sensor switch 35 When the packaged product approaches the store, it stops in the same manner as described above, waits for the packaged product to be transported by the central belt conveyor 3 to the store, and then the packaged product ascends to the upper roller 13 through the slit 17' of the casing 7 and turns. The items are transferred to the conveyor 48, and sorting at the store is performed by the conveyor 21 in the same manner as described above.

In this way, the sorting device ff 129' uses the computer IQ In to sort the packaged products 4 for the store in accordance with the program, and the left and right sorting is carried out by the conveyor 21.
21 accurately and smoothly.

Incidentally, for the sorting of an near the driven roller 43 at the end point of the central belt 3, after the sorting device 29' reaches the conveyor 21 and the sorting operation is completed, the sorting is carried out by the tilil device.
29' is returned to the initial position at a high speed to prepare for the next feed sorting process.

Although it is random, after the packaging and pricing work of the packaged products in the computer-controlled pre-processing device 47 is completed, various types of packaged products 4, 4 are processed.
. . . are conveyed in a random order in the direction of movement, sorting is carried out under computer control by reversing the drive roller 6 of the drive device 8 of the device 29'.
', the casing 7 and the turn conveyor 48 are integrally moved forward and backward by a predetermined stroke at a predetermined high speed, and the packaged product 4 is transported on the central belt conveyor 3 at a predetermined low speed. Sorting can be done freely.

The process consists of the forward and backward movement of the sorting machine @29' with respect to the central belt conveyor 3 as shown in Fig. 7, the forward V&path between the starting point and the ending point as shown in Fig. 8, and the forward movement from the ending point as shown in Fig. 9. This can be done accurately by selectively operating the rapid reverse.

Furthermore, as shown in FIG. 6, by switching between the upper central belt conveyor 3 and the lower central belt conveyor 3 using the air cylinder 40 of the switching conveyor 38, it is possible to selectively set multiple types of packaged products 4 for a very large number of stores. sorting is possible.

Therefore, as shown in FIG. 14, the sorting for each store, which is provided only on one side of the central belt conveyor 3, has two stages, upper and lower, compared to the configuration of the conveyors 21, 21, etc. By adding conveyors 21, 21, . . . for sorting on both the left and right sides, a large number of types of packaged products 4 can be selectively sorted for the number of stores, which is incomparable to the conventional method.

The embodiments of the invention of this application are, of course, not limited to the above-mentioned embodiments. For example, various types of pipes such as a turn conveyor and a divider provided at a pair of upper and lower rollers at the front end of a central belt conveyor may be used. The following aspects can be adopted.

In addition, it is of course possible to change the design by replacing the turn conveyor with a belt conveyor and using a roller conveyor.

For each sorting, it is also possible to provide an automatic boxing device or the like for containers at the tip of the conveyor.

It goes without saying that the device can be applied not only to the back center of a supermarket, but also to the backyard of a supermarket.

<Effects of the Invention> As described above, according to the invention of this application, basically in the back center of sorting products such as packaged products for each store of a supermarket, in the pre-processing packaging process, pricing process, etc. This system has the excellent effect of being able to carry out the sorting of processed products to a predetermined number of stores as quickly and accurately as possible while conveying them to stores using a central belt conveyor. is played.

Furthermore, even if the central belt conveyor, etc. conveys the packaged products at a predetermined speed to avoid damage to the packaged products, etc., the device does not perform sorting on the central belt conveyor. For sorting to stores at a speed faster than the speed of It also has the effect of being able to be sorted.

The conveyor belt of the central belt conveyor is folded back and wrapped around a pair of upper and lower rollers provided at the front of the casing of the sorting device, so that the central belt runs at a predetermined speed. For sorting on the conveyor, the casing of the conveyor can move forward and backward at the highest possible speed, so that the sorting device can quickly respond to the conveyor for sorting each store.
Moreover, when sorting to the frontmost store, even after the sorting device reaches the conveyor, it has the excellent effect of being able to rapidly move backward to the initial position.

Furthermore, for sorting, turn conveyors are installed on both sides at the tip of the casing of the device in a position orthogonal to the central belt conveyor, so that packaged products, etc., conveyed by the central belt conveyor are transported by the central belt conveyor. Conventional sorting can be carried out by moving the conveyor to the side by a turn conveyor while maintaining the same posture without changing the conveying posture at the top. Unlike turn conveyors such as roller conveyors, which are integrally provided with a curved tip, when packaged products are transferred from the belt conveyor to the turn conveyor, they are placed in a diagonal position, causing transfer clogging phenomena. The effect is that the sorting is carried out smoothly to the containers etc. on the conveyor, and therefore there is no clogging Fl on the turn conveyor.
There is no need for manual labor such as sorting, and complete rapid automatic sorting is effective.

In addition, since a turn conveyor that can freely rotate in the left and right direction is provided at the tip of the casing of the sorting device in contrast to the central belt conveyor, the sorting conveyors can be arranged on both sides of the central belt conveyor. ,therefore,
- The number of conveyors for sorting each store provided on the left and right sides of the central belt conveyor for books can be increased, and the excellent effect of improving the throughput of sorting can be achieved.

In addition, by making the central belt conveyor itself into upper and lower tank stages, etc., and interposing a switching conveyor between it and the pre-processing device,
Because sorting conveyors for multiple stores can be arranged on both sides of each central belt conveyor as described above, the overall number of stores to be sorted increases dramatically, and the processing capacity for sorting is significantly improved. Not only that, but it also has the effect of making full use of the limited plant space and area and improving the efficiency of the facility.

In addition, sorting is possible because the automatic movement of the central belt conveyor of the device against the guide frame can be made to correspond to the programmed movement of the packaged products conveyed to the belt conveyor, so that the type of conveyance and the type of store can be adjusted. Even when the number of products increases, speedy sorting has the effect of ensuring accurate processing.If the packaged products are perishable foods, or if freshness is required for prepared foods, etc., quick sorting is effective. This has the effect of shortening the time from processing to delivery.
