Description

  The present invention relates to a component supply system for supplying components to a process in a production line or the like.

In production lines such as automobiles, products are produced by assembling various parts in each process. It is desirable from the viewpoint of production efficiency that such parts are arranged in the vicinity of each process, and an engineer takes out the parts therefrom and assembles them to the assembly.
However, since there is often no sufficient space around the production line, the number of parts arranged in the vicinity of each process is limited. For this reason, each component is appropriately transported and supplied to the vicinity of each step. At this time, for example, parts are supplied using a supply cart as disclosed in Patent Documents 1 and 2.

Japanese Patent Laid-Open No. 10-329057 Japanese Patent Laid-Open No. 2005-224869

  However, when parts are to be supplied for each process, it is necessary to prepare a supply carriage for each. Then, when supplying parts, a plurality of supply carts go back and forth around the passage around the production line and stop, so the passage space is congested.

  Moreover, when the components are slid and supplied to a fixed shelf provided in the vicinity of the process like the supply cart described in Patent Document 2, there are the following problems. That is, since the arrangement direction of the parts and the sliding direction of the parts coincide with each other, the sliding direction is usually the longitudinal direction of the supply carriage due to its structure. Even if the sliding direction does not become the longitudinal direction, it is difficult to shorten the sliding direction if a large number of components are to be mounted.

Therefore, when the components are slid and supplied to the fixed shelf, it is necessary to arrange the supply carriage so that the longitudinal direction (slide direction) is orthogonal to the production line. However, it is difficult to increase the width of the line side formed along the production line, and the width of the line side is usually reduced from the viewpoint of space saving in the factory.
Therefore, when stopping the supply carriage on the line side, it is usually difficult to arrange the supply carriage so as to be orthogonal to the production line, and the supply carriage protrudes from the line side to the passage and blocks the passage. . Also, it is not preferable from the viewpoint of space saving to increase the width of the line side so that the supply carriage can be placed.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a component supply system that realizes space saving on the line side.

The present invention is a component supply system for supplying two types of components to two processes,
Each of the above-mentioned two types of parts is mounted and conveyed, and a carriage space for arranging the supply carriage is formed between each other while being fixedly arranged in the vicinity of the two steps, and A fixed shelf for receiving parts from the supply carriage,
The supply carriage includes a first rail that slidably holds a first part of one of the two types of parts, and a second rail that slidably holds a second part of the other type. In a plan view, they are arranged in parallel to each other, and discharge ports for discharging the components to the fixed shelf are provided at opposite ends in the longitudinal direction of the first rail and the second rail. In addition, a stopper that can be opened and closed is disposed at the discharge port,
Each of the two fixed shelves has a receiving port for receiving the component from the discharge port of the supply cart on the cart space side, and for supplying the component to each step. The supply port is provided at a position orthogonal to the receiving port and in the same direction as each other, and has a receiving rail for slidably holding the component,
When the supply carriage is arranged in the carriage space, the two discharge openings of the supply carriage are arranged opposite to the receiving openings of the two fixed shelves, respectively, and the first rail is disposed at the discharge opening. The component supply system is characterized in that the receiving rail of one of the fixed shelves is continuous with the receiving rail of the other fixed shelf, and the second rail is continuous with the receiving rail of the other fixed shelf at the discharge port ( Claim 1).

In the component supply system, the supply carriage has the first rail and the second rail. Therefore, since two types of parts can be supplied to two different processes at one time by one supply truck, the number of supply trucks that traverse the passage around the production line and stop on the line side is halved. As a result, space saving on the line side can be achieved.
Moreover, the fact that two types of parts can be supplied to two different processes at one time by one supply truck also reduces the man-hours of parts supply itself, thereby improving the production efficiency.
In particular, since the first rail and the second rail have the discharge port at the opposite ends, parts can be easily supplied to two processes arranged at two different positions. be able to.

  Moreover, a pair of said fixed shelf has the said receiving opening toward the said cart space formed between each other. And the said supply trolley provides the said discharge port in the mutually opposite side in the longitudinal direction of a 1st rail and a 2nd rail. Therefore, the supply carriage can be arranged so that the sliding direction, that is, the longitudinal direction thereof is parallel to the arrangement of the two steps. Therefore, the supply cart does not greatly block the line side or the passage when supplying parts. As a result, space saving on the line side can be achieved.

Moreover, since the said fixed shelf forms the said supply port in the position orthogonal to the said receiving port, a supply port can be arrange | positioned in the direction which goes to each process. Therefore, the worker can easily take out the parts from the fixed shelf and perform the assembly work efficiently. As a result, productivity can be improved.
In addition, since the parts can be supplied from the supply carriage to the fixed shelf by sliding the first rail, the second rail, and the receiving rail, the supply operation can be performed easily and smoothly.

  As described above, according to the present invention, it is possible to provide a component supply system that realizes space saving on the line side.

In the present invention, the first rail and the second rail of the supply carriage are inclined so as to descend toward the discharge port, respectively, and the receiving rail of the fixed shelf rises toward the receiving port. It is preferable to be inclined (claim 2).
In this case, since the parts can be moved from the supply cart to the fixed shelf by their own weight, the parts can be supplied more smoothly.

Moreover, it is preferable that a component holding member that engages with each other is interposed between the first rail, the second rail, the receiving rail, and the component.
In this case, parts can be supplied smoothly without damaging the parts.

In addition, the supply carriage has a rectangular shape in plan view, and a pair of universal wheels whose axles are freely changed in a horizontal plane are provided on the lower surfaces of both ends of one short side, and at both ends of the other short side. The lower surface is preferably provided with a semi-universal wheel capable of switching between a free state in which the axle freely changes in a horizontal plane and a fixed state in which the axle is fixed parallel to the short direction of the supply carriage. 4).
In this case, the supply carriage can be smoothly conveyed and the supply carriage can be smoothly set in the carriage space.

In addition, it is preferable that the two types of parts have symmetrical shapes.
In this case, since the mounting space of the components in the supply cart can be made symmetrical, it is possible to efficiently reduce the size of the supply cart.
For example, the part may be a front muffler for an automobile, the first part 41 is a right front muffler arranged on the right side of the vehicle, and the second part is a left front muffler arranged on the left side of the vehicle. It can be.
