The present invention relates to a product monitoring control device.

[0002]

[Prior Art]

 Conventionally, the inspection conveyor line monitors the results of product processing and assembly work in the previous process, and in order to distinguish between good and defective, inspectors stick to the machine side of the conveyor line for the number of lines and visually Is going.

The inspection of the product by the inspector is performed while the product is being conveyed on the conveyor line, and the speed of this conveyor line is determined by the takt time of the upstream process, and it is customary to inspect within that time. For example, from line (A) to (N), the product is transported from the upstream at every product transport pitch time, and the inspector checks this during transport of the product with a check time during transport to check whether the product is good or bad. Judgment was made and the product was made to flow to the subsequent process of the line.

[0004]

[Problems to be solved by the device]

 The above method requires as many inspectors as the number of conveyor lines, and if the difference between the product transfer pitch time and the check time during transfer becomes large, it becomes a dead time, which often becomes a non-negligible time when the number of conveyor lines increases. .

In the present invention, in order to eliminate the above defects, the monitoring time is set as the integration time of the time for checking a plurality of products, and is further integrated into the centralized monitoring time of the total number of lines. It is an object of the present invention to provide a supervisory control device for conveyor-conveyed products, which can eliminate the conventional dead time and improve the efficiency by continuously monitoring the products passing through a plurality of lines to the full capacity of the inspector.

[0006]

[Means for Solving the Problems]

 The present invention is provided with a plurality of upstream conveyors that are installed upstream of a production process to convey products, an inspection conveyor that is continuously installed on these upstream conveyors and accumulates and inspects the products, and the conveyance of the conveyed products. A feed counter that counts the number of pieces, a constant counter that detects that the number of conveyed pieces counted by the feed counter has reached a preset number, and the product is transferred to the inspection conveyor until the conveyed number reaches the set number. A stopper for staying, a shooting device that sequentially shoots the product when the constant counter operates, an image storage device that stores the product image information taken by this shooting device, and product image information that is extracted from this image storage device. It is equipped with a monitor device that displays divided images for each, and a control device that controls the accumulation, fast-forwarding, and sending-out of products and links them with the monitor device. A monitoring control device that conveyor conveying products.

[0007]

[Action]

 The conveyor control product monitoring and control device in the present invention conveys products by installing a plurality of upstream conveyors upstream of the production process, and installs inspection conveyors continuously on these upstream conveyors to accumulate and inspect the products. Then, the number of conveyed products is counted, it is detected that the number of conveyed products counted by the feed counter has reached a preset number, and the products stay on the inspection conveyor until the conveyed number reaches the set number. When the constant counter is activated, the product is sequentially photographed, the product image information taken by the image capturing device is stored, and the product image information is retrieved from the image storage device and displayed as a divided image for each product. And start sending it out and link it with the monitor device.

【Example】

 Next, an embodiment of the present invention will be described. In FIG. 1, 1 is a plurality of upstream conveyors that are installed upstream of the production process to convey the product 2, 3 is an inspection conveyor that is continuously installed on the upstream conveyor 1 and retains and inspects the product 2, and 5 is a conveyer The feed counter that counts the number of products to be transported, 8 is a constant counter that detects that the number of transports counted by the feed counter 5 has reached a preset number, and 4 is the number of transports that is set. Until the product reaches the inspection conveyor 3, the stopper 6 holds the product 2 on the inspection conveyor 3, 6 is a photographing device for sequentially photographing the product 2 when the constant counter 8 operates, and 9 is an image for storing the product image information photographed by the photographing device 6. A storage device 10 is a monitor device which retrieves product image information from the image storage device 9 and displays it as a divided image for each product, and 11 is a monitor device which controls retention, fast-forwarding and sending-out of the product 2. This is a control device that works in conjunction with 0. It is a multiple conveyor line that visually inspects the work results of the previous process for good and defective work results, and quantitatively aggregates the products that flow in sequence and fast-forwards to capture image information. This is a supervisory control device for conveyor-conveyed products, characterized in that it is memorized, divided into a plurality of monitor devices 10 and reproduced for each product, and inspected in lot units.

That is, in the present embodiment, in a plurality of conveyor lines, a certain number of products flowing on the conveyors are retained, and an image of each product is stored in the storage control device at high speed by an image capturing device such as an ITV camera. Then, it is displayed on multiple image monitors in front of the inspector sequentially for each conveyor line as a split screen, and the inspector checks the screens in sequence and after the inspection of the accumulated product is completed, The product 2 that flows through the tact T1 from the upstream conveyor 1 which is one line among multiple installations is sequentially fed to the inspection conveyor 3 having an accumulating function such as a roller top chain conveyor, which is a process to perform treatment. And are aligned by the stopper 4. The inspection conveyor 3 releases the stopper 4 when a predetermined number of products have been fed by the feed counter 5 and performs a high-speed feeding motion to pass the product line through the field of view of the photographing device 6 and convey it to the position of the end stopper 7. .

The photographing device 6 photographs with the constant counter 8 in correspondence with the product order and the images and sequentially stores the image information in the image storage device 9. After the image storage device 9 obtains a predetermined number of product image information. , Is displayed as a divided image for each product on the monitor devices 10 arranged collectively, and waits for the inspector's monitoring judgment.

The inspector makes an inspection pass / fail determination based on the image information of the monitor device 10 and transmits the pass / fail information to the control device 11 for each of the products that are divided and displayed.

The inspection conveyor 3 releases the end stopper 7 and sends out the product to the downstream conveyor 12 when the pass / fail signals for all the dividedly displayed products are received, and the predetermined work corresponding to the pass / fail signal is performed.

The difference between the line takt time and the inspection time can be effectively used by cyclically performing the above-mentioned work by the line where a plurality of lines are installed, the control device, and the monitor device installed collectively.

That is, after continuously judging the three products in the line LA illustrated in FIG. 2, it is possible to inspect each of the three products in the line LB and the line LC and inspect the line LA again. Only one inspector is needed.

In the present invention, the number of lines and the number of accumulated products are determined by the difference between the process takt time and the inspection time, the resolution limitation of the image monitor, and the like. It is natural that they are controlled by interlocking relationships.
