In the preceding stage of the means, there is a detecting means for sequentially determining the type and order of various types of workpieces being conveyed along a single conveyance line one by one, and a detecting means for determining the type and order of the various types of workpieces conveyed along a single conveyance line, and detecting the storing means and the carrying-in means based on a signal from the detecting means. By driving the means, each workpiece is stored in the storage means, and data on the type, position, and number of each workpiece stored in the storage means is held, and data of the same type of workpieces stored in the storage means is stored. The present invention is characterized by comprising a control means that drives the storage means and the unloading means based on the data when the number of workpieces reaches a predetermined number, thereby transporting only the workpieces of the relevant type to the outside.

[For production]

The detection means determines the type and order of various types of workpieces being conveyed along a single conveyance line. The control means drives the storage means and the carrying-in means based on the signal from the detection means, and stores each workpiece in the storage means. The control means also holds data on the position and number of workpieces stored in the storage means for each product type. When the number of works of the same type stored in the storage means reaches a predetermined number, the storage means and the carrying out means are driven by the control means based on the data, whereby a predetermined number of works of the same type are driven. Only the remaining parts are selectively transported outside.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 to 3.

This embodiment relates to a sorting device 1 that sorts a large number of types of tires that are successively conveyed into each type. When manufacturing many different types of tires in the same factory, there is no choice but to use separate production lines for each type, but due to equipment and personnel constraints, inspections are carried out at one location by consolidating each production line into the same line. In most cases, the products are separated by type. This embodiment also corresponds to such a case, and as shown in FIG.
After passing through the inspection process 4, it enters the inclined conveyor 5. Then, the tires 3 are placed in an upright position on an inclined conveyor 5, and the sorted tires are sent to the device 1.

A detection means 7 is provided on the conveyance line 6 that conveys the tires 3 in an upright position, and is configured to sequentially (distinguish) the types of the various types of tires 3 being conveyed one by one.

Along the conveyance line 6, a means 8 for transporting the tires 3 is provided at the ridge of the detection means 7. This carrying means 8 includes an elevator device 9 that holds the tires 3, circulates them in the vertical direction, and conveys the tires 3 to a desired height;
It has a buffer device 10 with a six-stage structure that temporarily holds the tires 3 transported therein. The buffer device 10 is a device with a shelf structure in which tires 3 to be sent to a storage means 12 to be described later are temporarily kept on standby, and each stage inclined toward the front can store four tires 3 each. Furthermore, a shutter 11 that is driven to open and close freely is provided at the exit of the buffer device IO.

Adjacent to the carry-in means 8, a storage means 12 for the tires 3 is provided. The storage means 12 has a rotary conveyor 13 that can hold the tires 3 in an upright position at predetermined intervals and circulate them. In this embodiment, the rotary conveyor 13 is stacked in six stages. It has a structure. Then, at one curved portion of each rotary conveyor 13, the tires 3 in the upright position are removed from the buffer device 10 of the carrying means 8.
It is configured to be imported one by one.

A means 14 for discharging the tires 3 is provided adjacent to the other curved portion of each rotary conveyor 13 constituting the storage means 12. This unloading means 14 includes a buffer device 1 having a six-stage structure.
5, and an elevator device 16 provided adjacent to the buffer device 15. The buffer device 15 is a device with a shelf structure that receives and temporarily holds one tire 3 at each stage from each rotary container 13 of the storage means 12. A button (not shown) for pushing the tires 3 on the rotary converter 13 into the buffer device 15 is provided on the entrance side of the buffer device 15, and a shutter 17 that is driven to open and close freely is provided on the exit side. The elevator device 16 is a bucket conveyor that rotates in the right direction in FIG.

In the figure, 19 is a palletizing device. This palletizing device 19 moves at a predetermined pitch in a direction perpendicular to the supply direction every time tires 3 in an upright position are supplied along the inclined conhair 18. Then, when the number of tires 3 to be carried out reaches a predetermined value, the tires 3 are stacked and stacked on the pallet 20.

Reference numeral 21 in the figure is an overflow line, which is provided to temporarily receive tires 3 sent from the container 2 when the storage means 12 becomes full or stops operating. In the figure, reference numeral 22 denotes a manual sorting line, which is provided for manually sorting the tires 3 when the storage means 12 side goes down. 23 is a pusher for manually sorting the tires 3 and sending them out to the line 22.

Next, the control means 24 that controls the carrying-in means 8, the storage means 12, and the carrying-out means 14, and its operation will be explained.

According to the sorting apparatus 1 having the control means 24 of this embodiment, it is possible to handle, for example, 70 types of tires. According to the control procedure of the control means 24, the tires 3 that are sent are rearranged and stored in the storage means 12, with a stock target value of 12 tires for each type. When the stock reaches 12 pieces, they are transported out of the apparatus one after another. In this case, the number of tires 3 of each type currently stored in the storage means 12 is considered to be six on average. Therefore, the storage capacity of the storage means 12 should be 70 x 6 = 420 pieces, but in reality it is set to 50% more than this value.
There are many empty positions on the rotary conveyor 13, and it does not take a long time to adjust the empty positions to the carry-in position. That is, the delivery can be carried out in a short time.

According to the control procedure of the control means 24 of this embodiment, each rotary conveyor 13 of the six-stage storage means 12 stores two items of the same type in a distributed manner. Therefore, when transporting tires 3 that have reached the target value, all stages of the rotary conveyor 13 are driven simultaneously to transport the tires 3 of the relevant type.
can be moved to the unloading position. That is, unloading can be carried out in a short time.

As shown in FIG. 3, the detection means 7 is connected to the control section 25 of the control means 24, and information about the types of tires 3 determined by the detection means 7 and their order is inputted. It has become. Then, the control section 25 first drives the elevator device 9 of the carrying-in means 8 based on the information from the detecting means 7, so that tires 3 of the same type enter two at a time from the lower rotary conveyor 13. The tires 3 are put into the buffer device 10 of the carry-in means 8 by changing the order of the tires. Then, the control unit 25 controls the storage means 12.
Buffer device l of each rotary conveyor 13 and carrying means 8
O is driven to carry the tires 3 in the buffer device io into the storage means 12. As a result, the control unit 25 determines which type of tire is stored at each address of each rotary conveyor 13, and address information for each type is written into the address storage means 26. At the same time, the stock number counter 27 counts the number of stored items for each type.

Next, when the tire 3 storage operation progresses and the number of tires of a certain type stored in the storage means 12 reaches 12, the controller 25 determines whether the tires are stored or not, based on the information in the stock number counter 27 and the address storage means 26. The means 12 and the carrying-out means 14 are driven to carry out only the tires 3 of the type that have reached a predetermined number to the inclined conhair 18. The unloaded tires 3 are then conveyed to the next process by a palletizing device 19.

As explained above, according to this embodiment, tires 3 of various types that have been transported in rows are rearranged while being tracked so that the management information (type, position, etc.) of each tire is made clear. The product is once stored in the six-stage storage means 12, and only the varieties that have reached the specified number are taken out from the storage means 12 based on the management information, so it is efficient with simple equipment that does not take up much space. It is possible to sort various workpieces.

In this embodiment, tires are used as the work to be sorted, but of course this is only a specific example. Further, the number of units for sorting and the number of stages of storage means are only examples, and it goes without saying that the present invention can be implemented in various other ways.

(Effects of the Invention) According to the present invention, various types of workpieces are tracked and stored in a common storage means in order to make management information clear, and only those types that have reached a predetermined number are selectively stored. It's time to move it out. Therefore, according to the present invention, there is no need to provide separate equipment for each type of workpiece, so space can be saved, equipment maintenance and management can be simplified, and equipment costs can be kept low. There is.
