Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply method and a component supply system for sequentially supplying components such as electric components one by one.

[0002]

2. Description of the Related Art For example, a component feeder for supplying electric components one by one is used for the purpose of assembling a printed circuit board by mounting electric components on a printed wiring board. As one type, electric components housed separately in a parts housing room are arranged in a line,
There is a bulk feeder that supplies individually. This bulk feeder has an advantage that the supply cost of electric components can be reduced as compared with a tape feeder that has been widely used in the past. The tape feeder feeds each accommodating recess by feeding a taped component in which electrical components are accommodated in each of a large number of accommodating recesses formed side by side in the longitudinal direction of the carrier tape at a constant pitch in the longitudinal direction. This is a type of feeder that supplies electrical components by positioning it in a section. In general, a cover tape is provided to cover the accommodating recess of the carrier tape, the cover tape is peeled off from the carrier tape, and the accommodating recess is opened. Parts are removed. Therefore, a carrier tape and a cover tape are required, and it is unavoidable that the cost for supplying parts increases. Further, there is a problem that disposal of the carrier tape and the cover tape after use is costly and requires consideration for environmental problems. In particular, when the carrier tape and the cover tape are made of synthetic resin, the latter problem is significant.

[0003] These problems can be solved by using a bulk feeder, but the bulk feeder has a problem that the reliability of component supply is lower than that of a tape feeder. This problem is becoming more important as the performance of component mounting equipment improves and the cycle time required to mount one electrical component is reduced. Of course, efforts have been made to improve the high-speed supply capability of the bulk feeder itself, but at present there is not enough available. In the above, the supply of electric components has been described as an example. However, the same problem occurs in the supply of other components that need to be supplied at the same speed.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and even if the high-speed supply capability of the bulk feeder itself cannot be said to be sufficient, parts supply can be performed without hindrance. The present invention provides a component supply method and a component supply system according to the following embodiments. As in the case of the claims, each aspect is divided into sections, each section is numbered, and if necessary, the other sections are cited in a form in which the numbers are cited. This is to facilitate understanding of the present invention,
The technical features and combinations thereof described herein should not be construed as limited to those set forth in the following sections. Further, when a plurality of items are described in one section, the plurality of items need not always be adopted together. It is also possible to select and adopt only some of the items. (1) A plurality of bulk feeders for supplying the same kind of components are arranged in a state where their component supply units are arranged in a line, and a plurality of components supplied successively are supplied from different bulk feeders in principle. A component supply method (claim 1). As described above, if a plurality of bulk feeders that supply the same type of parts are set as one set, and the components are supplied from any of the bulk feeders belonging to the set, one bulk feeder can surely be provided. Even when components cannot be supplied, it can be ensured that components are supplied from a set of bulk feeders. The bulk feeder in this section has been developed directly for supplying electric components, but can be generally used for supplying other components. (2) The component supply method according to the above mode (1), wherein the plurality of bulk feeders are arranged adjacent to each other. It is also possible to arrange the bulk feeders belonging to one set apart from each other, and to arrange another feeder such as a bulk feeder or a tape feeder for supplying another component between them. However, if the bulk feeders belonging to one set are arranged adjacent to each other, the supply order of the components supplied by the bulk feeders belonging to the one set and the components supplied by another feeder does not reverse. Therefore, it is possible to prevent a program for controlling component supply and a program for handling supplied components (for example, a program for mounting an electric component on a printed wiring board) from becoming complicated. If the spacing between the bulk feeders belonging to one set is fixed, it is particularly easy to avoid complicating the component supply control program. (3) The component supply method according to the above mode (1) or (2), wherein the order of supplying the components of the plurality of bulk feeders is determined in advance. Even if the supply order is determined in advance, an advantage is obtained in which a plurality of bulk feeders are set as one set and components are supplied in cooperation with each other, and a component supply control program can be simplified. For example, when two bulk feeders are set as one set and parts are alternately supplied, there is a performance in which one part can be surely prepared in the component supply unit while each bulk feeder operates twice. If it is, the parts can be surely supplied every time by the cooperation of the bulk feeders. (4) Next, in the bulk feeder to supply parts,
In the case where components are not yet prepared in the component supply unit, components are supplied from a bulk feeder to be supplied next. In the component supply device described in (3), if the component is not ready in the component supply unit in the bulk feeder to which components are to be supplied next, the operation of the device that receives the component supply must be stopped. However, by adopting the features of this section, it is possible to reduce the chance of having to stop. If the bulk feeder to which components are to be supplied next is not ready, but the bulk feeder to which components are to be supplied thereafter is ready, then the latter bulk feeder is used to supply components. There is no need to stop the supply of parts. In order to carry out the method of this section, it is necessary to provide a detection device for detecting whether or not the preparation of the components in the component supply unit has been completed in each bulk feeder. Next (5)
The same applies to the term. (5) Among the plurality of bulk feeders, a bulk feeder to which a component is to be supplied next is determined based on a component that has already been prepared in the component supply unit. Parts supply method. When the number of bulk feeders belonging to one set is two, the component supply method according to the above item (4) is the same. However, when the number is three or more, the component supply method according to this item is better. Opportunities to shut down the device that receives the supply of parts are reduced. In order to supply parts as evenly as possible from multiple bulk feeders,
It is desirable, but not essential, to determine the bulk feeder to which the component will then be supplied. For that purpose, it is necessary to store in the storage means the number of times that the component has been supplied or the number of times that the component has not been supplied for each bulk feeder. (6) Each of the taped components having the same type of components held on a carrier tape is held, and while the carrier tape is fed in the longitudinal direction, the components held on the carrier tape are sequentially sent one by one in a component supply unit. A state in which at least one tape feeder to be supplied and at least one set of a plurality of bulk feeders that supply one and the same type of component one by one in each component supply unit are arranged along a line. And a component supply method for supplying components from both the tape feeder and the bulk feeder to one circuit substrate. According to this method, components can be mixed and supplied from both the bulk feeder and the tape feeder. (7) The tape feeder and the bulk feeder and a common component holder for receiving components supplied from the feeders are relatively moved along the line, and the component holder is moved to the next feeder to receive the component. The component supply method according to the above mode (6), wherein the component holder and the feeder are brought closer to each other while the component holder is opposed to the component supply unit, and the component is held by the component holder. One embodiment of the method of the above item (6) is obtained. (8) The plurality of components successively supplied from the bulk feeder are, in principle, supplied from different bulk feeders among the plurality of bulk feeders belonging to each set of the at least one set of bulk feeders. (6) Clause or (7)
Item supply method according to claim (claim 3). According to the component supply method of this mode, components can be supplied from the bulk feeder at the same speed and reliability as the tape feeder. The features described in any one of the above modes (2) to (5) are applicable to the component supply method according to this mode. (9) A plurality of sets of a plurality of bulk feeders that supply components of the same type mutually receive a component supply device in which the component supply units are arranged in a line and a component supplied from the bulk feeder. A component holder for holding the component, a moving device for relatively moving the bulk feeder and the component holder along the line,
A moving device control device for controlling a plurality of parts successively supplied from each of the plurality of sets to be supplied from different bulk feeders in principle (claim 4). According to the parts supply system in this section, (1)
The method of paragraph can be implemented. The features described in paragraphs (2) to (8) are also applicable to the component supply system according to this paragraph. (10) The bulk feeder belonging to each of the plurality of sets includes:
The component supply system according to (9), including a feeder fixing device that shares at least the feeder main body and detachably fixes the feeder main body to the feeder support base.
