Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a parts assembly and manufacturing device in an automatic assembly line using robots and the like.

(Prior art) In the marshalling station and assembly station of a conventional automatic assembly line, each station controller is preset with operation details, operation sequences, and operation positions, and when an assembly pallet arrives at the corresponding station, It only performs the registered actions. Furthermore, although the assembly pallet has a function of holding the position of the workpiece from the transport platform, it does not have an intelligent (multi-functional complex) function that instructs each station controller to operate.

For this reason, the station controller has a series of operation contents, order, and operation position data about which parts are to be assembled from where to where at each station.
It is difficult to produce products with mixed models (mixed flow), and it requires a great deal of effort to replace programs, data, etc. when switching between different models in lots.

(Problems to be Solved by the Invention) The present invention provides operational details of a two-assembly station controller in order to solve the above-mentioned problems.

We have introduced an intelligent assembly pallet that receives manufacturing parameters from a manufacturing control computer and can deploy the order and operation position data by itself and instructs each station controller.The manufacturing control computer also has an automatic parts warehouse for marshalling. The present invention also provides a parts assembly and manufacturing device capable of transmitting the best manufacturing parameters reflecting the number of parts in stock and the status of each station to an intelligent assembly pallet by connecting online with each station controller.

(Function) By combining a manufacturing control computer and an automatic parts storage warehouse connected to a marshalling station, the present invention avoids long assembly line stoppages due to equipment failures due to running out of parts or partial assembly stages. To improve the followability to changes in products or parts, and to simplify and simplify the functions of the station controller.

(Example) The present invention is an automatic assembly line using robots, etc., and instead of setting work contents, operation sequences, and operation positions for a marshaling station and an assembly station downstream thereof in advance for each equipment, By receiving manufacturing parameters in the form of a manufacturing instruction card from a manufacturing control computer installed on the side, the operator can decide which parts to take out from the automated warehouse and in what order, and then disassemble the marshalled parts to the downstream assembly station.・Assign
This relates to an intelligent pallet that has the function of determining the operating sequence and operating position of each assembly station equipment and instructing the transmission of operating reference data from the pallet to the station controller when the intelligent pallet arrives at the assembly station, and is used for manufacturing management. a manufacturing instruction card that stores instruction information; a manufacturing instruction card writing device that reads information from the manufacturing instruction card; an assembly device that disassembles or assembles parts according to instructions from the manufacturing instruction card writing device; Or a part comprising a product transport device for transporting assembled products, a loading/unloading device for loading or unloading the product on the product transport device, and a product monitoring device for monitoring the manufacturing status of the product. This is assembly manufacturing equipment.

That is, the present invention obtains manufacturing parameters from the ground-side manufacturing control computer in the form of a manufacturing instruction card to determine the parts to be taken out from the automated warehouse and the order in which to take them out.
In addition, an intelligent assembly pallet and its assembly pallet are used, which are characterized by disassembling and allocating work for marshalled parts to downstream assembly stations, and calculating in advance the operation sequence and operation position of each assembly station equipment. It is an automatic assembly line with
The figure shows an external view of an intelligent assembly pallet that is the subject of the present invention, and FIG. 2 shows a control configuration diagram of the pallet.

Externally, it has a manufacturing instruction card holder 25 for receiving and receiving manufacturing parameters instructed from a manufacturing control computer 40, an assembly pallet CPU storage area 6, and a transmission terminal 3 for transmitting manufacturing parameters to station controllers 41 to 43. It is characterized by The top surface of the pallet is divided into two parts depending on how it is used. One is a pre-marshalling space 5 for parts to be assembled, and the other is a product assembly space 4.

Furthermore, the upper surface of the pallet is assumed to be uneven depending on the shape of the parts. Since the manufacturing parameters received from the manufacturing control computer 40 are expanded into work elements for the marshalling station 22 and each assembly station 26, 27, this is the role of the pallet CPU10 and is the central function of the present invention.

Next, an example of an automatic assembly line using this intelligent assembly pallet 1 is shown in FIG. 3, and FIG. 4 is a configuration diagram of a management control system for this line.

The manufacturing control computer 40 includes a marshalling controller 41 with an automatic warehouse and an assembly station controller 42.
．． It is connected online to 43 and grasps the amount of parts in stock and the operating status of each assembly station in real time. When the manufacturing control computer 40 determines the type of product to be produced next, it writes the manufacturing parameters into an IC card via the manufacturing instruction card writing device 23 connected online. is set in the manufacturing instruction card holder 2 of the intelligent assembly pallet 1 by the manufacturing instruction card inserting machine 25 via the manufacturing instruction card aligning machine 24. Power is supplied to the assembled pallet by feeder supply from the ground side or battery holding system. Both are possible.

The assembled pallets are sequentially conveyed to the stations by the base conveyor 21.

The first assembly station is a marshalling station 22 with an automatic warehouse, and each station has an information exchange probe 31 with the intelligent pallet 1,
When the intelligent assembly pallet 1 arrives at the corresponding station, the probe 31 is driven and connected from the station side.

After that, the operation data of the station equipment is transmitted from the intelligent pallet 1 to each station controller 41~
43, and equipment operation is started.

Products are assembled by the assembled pallet passing through the final station 27, and the products are picked from the assembled pallet 1 by the product unloader 30 and transported to the next process. The manufacturing instruction card is processed by a manufacturing instruction card extraction and recovery device 28 connected online to the manufacturing control computer 40.
The manufacturing instruction card is taken out from the manufacturing instruction card holder 2. The taken out manufacturing instruction card is prepared and stored as the next instruction card.

FIG. 5 shows the functions of the manufacturing control computer, and FIG. 6 shows the functions of the Implige End Palette CPU.

Next, the process will be explained according to the flow shown in FIG.

The manufacturing control computer 40 is powered on every morning, and when the system is started up and completed, it exhibits the functions shown in FIG. Writing to the manufacturing instruction card continues via the manufacturing instruction card writing device 23 until today's production quantity is achieved. Incidentally, the manufacturing control computer 40 is connected to the equipment constituting the system as shown in FIG. The written manufacturing instruction cards are aligned and positioned by the manufacturing instruction card aligning machine 24, and then placed in the manufacturing instruction card holder 2 of the intelligent assembly pallet 1 by the manufacturing instruction card inserting machine 25.
is set to The inserted manufacturing instruction card is read into the pallet CPU10 shown in the configuration of FIG. 6th
The figure shows the functions of the palette CPU10.

Now, when the intelligent assembled pallet 1 arrives at a certain position in the marshalling station 22 with automatic warehouse, the information exchange probe 31 with the intelligent pallet is driven and comes into close contact with the station controller transmission terminal 3 on the assembled pallet 1. After that, the intelligent pallet CPU10 transmits the part code and the position information of the part marshaling space 5 for all the corresponding parts, that is, the operation sequence and operation position information of the corresponding marshalling equipment, to the marshalling controller with automatic warehouse 41. Marshaling controller with automatic warehouse 41
is the received part code, operation sequence.

Based on the operation position information, the corresponding parts are retrieved from the automatic warehouse and placed in the parts marshalling space 5.

When all the parts are set on the intelligent assembly pallet 1, the base conveyor 21 transports the intelligent assembly pallet 1 to the first assembly station 26, which is the next stop position.

The intelligent assembly pallet 1 stopped at the fixed position of the first assembly station equipment transmits the operation sequence and operation position of the first assembly station equipment determined in advance by the pallet CPU10 via the information exchange probe 1. The operating sequence and operating position of the equipment is to sequentially transport the parts placed in the parts marshalling space 5 on the intelligent assembly pallet 1 to the product assembly space 4 and assemble the parts.

In this way, the assembly station controller does not have a fixed operation order and operation position, but the assembly pallet is completed by sequentially passing through the assembly station to the 0 component assembly layer instructed by the pallet CPU10 for each intelligent assembly pallet. Goods can be made. Next to the last n-th assembly station 27, there is a manufacturing instruction card extraction and recovery device 28.
The manufacturing instruction card is removed from the manufacturing instruction card holder 2 from the intelligent assembly pallet 1 that has stopped.

The taken out manufacturing instruction card is placed in a manufacturing instruction card writing device for the next production instruction. The assembled products are transferred from the assembly pallet to the product conveyor 29 by the product unloader 30. The empty intelligently assembled pallet 1 is transported back by an empty pallet transport conveyor installed below the base conveyor 21.

〔Effect of the invention〕

According to this technology, there are constraints such as 1 assembly station for parts stored in an automatic warehouse, 2 the size and top surface shape of the assembly pallet, and the chuck shape of each automatic machine, but within that range, the Flexible production is possible.

Furthermore, since there is no need to store a fixed operation sequence (algorithm) and operation position data in each station controller as in the past, the standardization of the control device is accelerated and the station equipment can be easily transferred to other lines.
