DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component assembling system for assembling supplied components to produce a product such as a magnetic tape cassette in a production line.

[0002]

2. Description of the Related Art Conventionally, in a production line for producing products such as a magnetic tape cassette, for example, an operator is arranged for each part in charge on one side or both sides of a conveyor (belt conveyor) and is conveyed by the conveyor. I take the unfinished product in front of me, incorporate my parts into it, and return it to the conveyor again.

[0003]

However, in the above-mentioned conventional production line, an upstream worker, who receives the product from the transfer device, can easily take the product and work on the downstream side. Because workers who have already assembled parts also flow, the product to be worked on does not readily flow, and there is a waiting time until the product to incorporate parts flows, resulting in poor work efficiency. There was a problem.

[0004] Further, since products are taken from the transport device, parts are incorporated into the products, and the original transport device is returned to the original transport device, unfinished products to be worked on are already placed on the transport device. And finished products are mixed, and the operator has to troubleshoot whether the products on the transfer device are unfinished products or finished products. Also, when returning the product incorporating the parts to the transporting device, the worker had to return it by himself, so he had to wait until finding an empty space to return the product on the transporting device, causing the work efficiency to deteriorate. There is also a problem that there is.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a parts assembling system which achieves work efficiency without waiting for an operator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a component assembling system according to the present invention will be described in detail based on preferred embodiments shown in the accompanying drawings.

FIG. 1 is a perspective view schematically showing a component assembling system in a production line for assembling a magnetic tape cassette according to an embodiment of the present invention. The component assembling system of the present invention is a system in which a plurality of workers are conventionally arranged on a long belt conveyor, but is a system for each individual. As shown in FIG. 1, the component assembling system 10 of the present embodiment has two stages of belt conveyors. The upper belt conveyors (unfinished product supply conveyors) 12 and 12 are used to supply the workers 16 and 16 with the half of the unfinished product magnetic tape cassette into which the components are to be incorporated. The belt conveyor (finished product unloading conveyor) 14 is for unloading a work 18 of a completed product into which parts are incorporated. Also, the upper unfinished product supply conveyors 12, 12
Is divided into two as shown in FIG. 1, and one unfinished product 1 is placed on each of the conveyors 12, 12.
6 and 16 are mounted. Each belt conveyor 1
2, 12, and 14 can be driven separately.

A work desk 20 is provided in front of the lower-stage finished product unloading conveyor 14. The work desk 20 is used by the operator to take the work 16 of the unfinished product from the unfinished product supply conveyer 12 and to perform a work of incorporating components. The work desk 20 is provided with a rain gutter 22 at a front end thereof for preventing parts from falling during work. Further, the work desk 20 is provided with a pusher 24 for pushing out the work 18 of the finished product placed at the predetermined position onto the finished product carrying-out conveyor 14.

A carriage 26 is placed at the lower front of the work desk 20. On the carriage 26, a large number of containers (not shown) containing parts are loaded in order to supply parts to the worker. With the progress of the worker's part assembling work, the container that has lost the part is removed. As a result, when the number of containers stacked on the trolley 26 is reduced, the operator has to take parts from the container located at a lower position on the trolley 26, which makes it difficult to take parts. In such a case,
When a worker sitting on a chair (not shown) next to the cart 26 steps on a lever 28 provided on the cart 26, the height of the cart 26 increases.

The component assembling system 10 of the present embodiment is provided with various sensors so that the operator can perform as much as possible other than assembling the components as automatically as possible. First,
On the upper unfinished product supply conveyors 12, 12 for supplying unfinished products 16 to the workers, the unfinished products 16, 16 must always be present thereon.
Incomplete product detection sensors 30, 3 for detecting the presence or absence
0 is provided.

The work desk 20 has a pusher 24 for pushing the finished work 18 onto the finished product unloading conveyor 14 when the finished work 18 is placed at a predetermined position. A completed product detection sensor 32 is provided to detect whether or not the completed product 18 exists at a predetermined position on the desk 20. In addition, the work desk 20 further securely transfers the finished product work 18 to the finished product unloading conveyor 1.
An empty space detection sensor 34 for detecting the empty space of the finished product unloading conveyor 14 is provided in order to push out the empty space 4.

The configuration of the component assembling system 10 according to the present embodiment has been described above.
As shown in FIG. 1, three or four component assembly systems 10 for one worker are connected side by side to form one production line. Hereinafter, the operation of the present embodiment will be described.

In the line of FIG. 2, it is assumed that the component assembling system 10c is upstream and the component assembling system 10a is downstream. Unfinished work 16 (16a, 16
b, 16c) are supplied from the upstream side. When the unfinished product detection sensor 30 (30a, 30b, 30c) determines that there is no unfinished product on the unfinished product supply conveyor 12, the unfinished supply conveyor 12 upstream of the unfinished product supply conveyor 12 is driven. The unfinished products 16 are supplied in order from the upstream side, and two unfinished products 16 are always supplied to the worker.

For example, when the worker of the component assembling system 10b takes the unfinished product work 16b from the unfinished product supply conveyor 12b on the left side, the unfinished product supply conveyor 12b on the right side and the unfinished product on the upstream side therefrom. The supply conveyor 12c is driven, and the unfinished work 16b is now taken, and the unfinished work 16b is replenished to the unfinished supply conveyor 12b. The supply of the unfinished product work 16c to the unfinished product supply conveyor 12c on the most upstream side is performed automatically, but may be performed manually.

Each worker takes an unfinished product 16 from the unfinished product supply conveyor 12 and places a pin or a pin on a half of a magnetic tape cassette incorporated in the unfinished product 16 on each work desk 20. Install springs and other parts. At this time, even if a small part is likely to roll down from the work desk 20, the rain gutter 2 for preventing fall as shown in FIG.
2 receives the part. When the components have been incorporated, the worker places the completed work 18 at a predetermined position on the work desk 20. When the completed product detection sensor 32 detects it and the empty space detection sensor 34 detects an empty space on the finished product unloading conveyor 14, the pusher 24 is driven, and the completed workpiece 18 is pushed out into the empty space. The finished product is conveyed out by the conveyer 14.

At this time, the components to be incorporated are supplied by a container (not shown) loaded on the carriage 26 next to the worker. However, the components in the container are used, and the number of loaded containers is reduced so that the components are collected. If it becomes difficult,
When the operator steps on the lever 28 provided on the lower side of the trolley 26, the height of the trolley 26 increases, and parts can be easily removed. Then, when the parts on the trolley 26 are completely gone, the operator pushes the trolley 26 to go to get the parts,
Alternatively, the information may be supplied by an operator other than the operators arranged on the line.

As described above, in the present embodiment, since the production line is constituted by the individual belt conveyor,
Until now, workers who had previously only installed part of the parts can now install all parts in one product, and assemble parts efficiently. Is now available. Further, when the number of workers is changed, it is only necessary to add or remove the personal belt conveyor according to the present embodiment, so that the production line can be easily changed.
In addition, since the unfinished product supply conveyor and the finished product unloading conveyor are separated, unfinished products and finished products do not flow together as before, and it is judged whether they are unfinished products or finished products each time There's no need to wait, no waiting,
Work efficiency has improved.

Further, since the work of the finished product is automatically loaded on the finished product take-out conveyor, the operator finds an empty space while watching the situation where the product flows on the belt conveyor as in the past. This eliminates the need for the operation of putting the finished product into the device, thereby further reducing the time and improving the efficiency. In addition, the total output of each worker can be ascertained by counting the number of times the pusher drives the finished product onto the finished product take-out conveyor.

Although the component assembling system of the present invention has been described in detail above, the present invention is not limited to the above-described components, and various modifications and changes can be made without departing from the gist of the present invention. Of course you can do it.

[0023]

As described above, according to the present invention, the efficiency of the parts assembling work is improved without waiting for the operator.
