Abstract

PURPOSE:To facilitate mapping of a production program as well as to produce the number of planned production units in an accurate manner by feeding a specified assembly line in production sequence based on the program, with the sequentual parts loading carriage, taking these parts out of the parts loading carriage attended by an operator, and assembling them on the assembly line. CONSTITUTION:All parts per carriage at each product to be preassembled are sorted in type and loaded on a large L-type product carriage L (L sign carriage), a medium M-type product carriage M (M sign carriage) and a small S-type product carriage (S sign carriage). When the M sign carriage is fed to a production assembly line 1 of the first one, the L sign carriage for the second one and the S sign carriage as the third one, respectively on the basis of production planning, each of operators (A), (B), (C) and so on assembles parts in sequence being fed in to the extent of completing assembly with his responsible range, and then passing over the work to the next person responsible for the following process, thus these parts are assembled in succession.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an assembly method in a factory that produces agricultural machinery, machinery for various plants, and the like.

If there are many models and models of conventional technology products and the production quantity of each model or model is small, or if a small to medium-sized company produces miscellaneous products in small quantities, it is necessary to configure multiple assembly lines. This is difficult in terms of cost and factory space, and for this reason, the models and models produced are changed hourly or daily.

Products were produced separately.

Problems that the invention aims to solve In conventional production and assembly methods, a certain number of identical models, models, or products are assembled in succession.

It had the disadvantage that it was difficult to make a production plan, it was easy to fall into the trap of overproducing or underproducing the number of units produced, and the assembly workers lost their sense of tension through simple tasks, leading to assembly errors.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a means for solving the above-mentioned problems. Alternatively, all the parts required for each model or each product are loaded onto a specific parts loading truck, and the parts loading trucks in that order are sent to the predetermined assembly line in the production order based on the production plan, and the assembly process is followed. This is an assembly method for mixed production in which 1) the parts loading cart moves automatically or manually, and 1) an assembly worker takes out the parts from the parts loading cart and assembles them.

Functions and Effects of the Invention According to the present invention, the parts for each product to be assembled are loaded in advance onto a predetermined parts loading cart (one or two is suitable), and the Product trolley L
The products are shipped from the parts collection center after being divided into carts M for medium-sized M-type products (32 L-can carts), carts S for small-sized S-type products (S-campan carts).

and.

Based on the production plan, assembly workers are sent to one attached assembly line 1. That is, for example, first M
Kan 3 bogie car M, 2nd L campan bogie L, 3'
! The #th S camper truck S and the fourth L truck 32 truck are sent to the assembly line and assembled according to the production assembly plan based on the shipping time, departure schedule, or planned production quantity. Therefore, this single assembly line can assemble a wide variety of products according to a flexible plan, although the number of products is extremely small, ie, one or two.

For this reason, according to the present invention, production plans can be easily established and a planned production schedule can be easily established in order to mix and assemble a very small number of the same model, model, or product on one assembly line. It is possible to assemble and produce a large number of units accurately, and moreover, each assembly worker always performs the assembly work with a sense of tension, so that simple assembly mistakes do not occur.

Embodiment To describe an embodiment of the present invention in detail, a parts assembly center set up in a factory having an assembly line 1 receives production model, model, etc. from each parts production department, production factory, subcontractor, commercial parts purchaser, etc. An embodiment in which all the necessary parts of the product to be produced are assembled, and at this parts collection center, all parts for each product to be assembled are loaded onto a predetermined parts loading trolley (one in the embodiment). Loading is then divided into trolley L for large L-type products (32 L-type products), trolley M for medium-sized M-type products (42 M-type products), and trolley S for small S-type products (S campan trolley). .

Then, based on the production plan, one production assembly line 1 with assembly workers will have 42 M-ring carts,
The second L-camp 32 truck will be sent, and the third will be the S-camp truck.

Then, an assembly worker (
A), (B), (C)...... pass the baton to the person in charge of assembly of the first stage of assembly until the assembly process is completed in the field of responsibility for the assembly of the models in the order in which they are sent. Assemble the parts below.

Thus, in one example case, a medium product is assembled followed by a large product, followed by a small product. Then, in the fourth stage, either M or S type products will be assembled based on the plan.

In the embodiment, the assembly of a mixture of models of the same product has been described, but it is also possible to assemble a mixture of different types of products, or to assemble a mixture of a single model and a mixture of different types of products.

In addition, when loading parts for each model, model, or product onto a parts loading trolley, all parts manufactured in-house at our own factory, outsourced parts, and commercially available parts are collected in one place. We have explained an example in which parts are selectively loaded for each model or product, but parts completed in-house, outsourced parts, and commercially available parts are loaded in advance for each model or product.
A designated transport box is easily placed for each vehicle, and the receiving box is designed to be easy to accommodate.
It will be more efficient if each transport box is loaded onto a loading cart.

Furthermore, when loading parts onto a parts loading trolley, it is natural to take into account the ease of taking out the parts based on the order of assembly, but the parts corresponding to the assembly worker's assembly responsibility process can be separated and recognized. It is effective to avoid assembly errors by loading the parts into the container.

(b) and (c) indicate assembly workers.

Claims (1)

[Claims] When producing many types of products with a large number of production models and models and a small number of each product, or products in small quantities, it is necessary to specify all the parts required for each production model or model, or for each product. The parts loading carts are loaded onto parts loading carts, and the parts loading carts in that order are sent to the predetermined assembly line in the production order based on the production plan. An assembly method in mixed production of a system in which parts are taken out and assembled from a parts loading cart that travels along with it.
