[0008]

According to the present invention, a reciprocating movement of a component supply unit in which component supply units are arranged to supply various components in the arrangement direction causes a component supply unit of a component required by the component handling unit in each case. In order to achieve the above object, a unit operation of repeatedly performing a work involving arrangement of each part in a predetermined pattern while sequentially receiving supply of necessary parts is performed. In the component handling method of the present invention, the component supply units of necessary components are arranged according to the component arrangement operation order, and the component handling unit performs the component arrangement in the forward arrangement operation in a predetermined pattern due to the forward movement of the component supply unit. The parts are supplied sequentially in opposition to the respective parts supply units of the necessary parts, unit work involving arrangement of various parts in a predetermined pattern by forward arrangement work, and the parts handling unit is operated by the parts supply unit. of In the reverse arrangement of the components in the predetermined pattern by the backward movement, the parts are sequentially supplied in opposition to the respective component supply units of the necessary components and the components are supplied, and the various components are arranged in the predetermined pattern by the reverse arrangement operation. It is characterized by repeatedly performing the unit work with the above, and continuously performing the unit work with the arrangement of the parts in a predetermined pattern,
In the component handling method according to the second aspect of the present invention, the components are grouped according to a difference in handling speed such as a limit speed of handling by the component handling unit or a limit speed of movement of the members to be arranged for arranging the components. The same treatment as in the first aspect of the invention is performed for each group.

According to the configuration of the first aspect of the present invention, the parts handling unit performs the unit work involving the arrangement in a predetermined pattern in the forward arrangement work for the parts sequentially supplied by the forward movement of the part supply unit. Performing the parts sequentially supplied by the backward movement of the parts supply unit, the parts handling unit performs the unit work with the arrangement in a predetermined pattern in the reverse arrangement work opposite to the forward arrangement work, The parts handling unit can receive the parts and perform the unit work with the arrangement in the same pattern continuously in both the forward movement and the backward movement of the parts supply unit, and can reverse the last handled parts in the forward arrangement work. Since the first part handled in the direction arrangement work is common, and the last part handled in the reverse arrangement work and the first part handled in the forward arrangement work are common, it is necessary to repeat the unit operation several times in the forward direction. In both the case of switching from the row operation to the reverse arrangement operation and the case of switching from the reverse arrangement operation to the forward arrangement operation, the component supply unit does not have to move in order to supply the initial components for switching. Thus, productivity can be improved and product cost can be reduced. In the case where the unit work involving the arrangement of the components in a predetermined pattern is repeatedly performed at a plurality of locations on one of the components to be arrayed as in the invention of claim 3, particularly, the replacement of the array target members and the time for the replacement are not required. Since the unit operation can be repeated, the continuous operation can be performed without a loss time for the return movement of the component supply unit, so that the productivity is further improved.

In the configuration of the second aspect of the present invention, parts are handled in the same manner as in the first aspect of the invention, separately for those having different handling speeds. As a result, a difference in handling speed between parts having a slower handling speed and a component having a faster handling speed being arranged later on the member to be arranged cannot withstand the handling speed. The same advantages as the first aspect of the invention can be exhibited without the influence of the above.

In the forward arrangement work, the parts are supplied sequentially in such a way as to face the respective component supply units of the necessary parts, and the unit work involving the arrangement of various parts in the predetermined pattern by the forward arrangement work is performed. First control data for controlling the component supply unit and the component handling unit, and the component handling unit supplies each component of a component required each time in a reverse arrangement operation of components in a predetermined pattern by the backward movement of the component supply unit. Second control data for controlling the component supply unit and the component handling unit so as to receive the supply of components sequentially facing the unit unit and perform the unit operation involving the arrangement of various components in a predetermined pattern by the reverse arrangement operation. Are alternately executed based on the switching control data, or the first control data is alternately executed in the forward direction and the reverse direction based on the first and second execution instruction data, so that the unit work is continuously performed. It is characterized in that it is performed in a targeted manner.

Numerical data da indicated by the coordinate position and the position of the component supply cassette to be moved to the component supply position of the component supply unit 1 in order to supply components required for this mounting coincide with the reciprocating movement direction of the component supply unit 1. The switching control data D is simply given by the numerical data db indicated by the position on the axis.
Reference numeral 3 designates an instruction for alternately switching and executing the first and second control data D1 and D2, and is given in a very simple manner. It is possible to automatically and continuously perform unit work involving arrangement in a predetermined pattern.

In the second embodiment, as shown in FIG. 4, the first control data D1 of the first embodiment is converted into execution instruction data D4 based on first and second numerical data dc and dd for switching between forward and reverse arrangement directions. The unit work is performed alternately in the forward direction and the reverse direction, and the unit work is continuously performed by alternately repeating the forward arrangement work and the reverse arrangement work as in the first embodiment.

Therefore, the mounting instruction data D1 in which the numerical data da and db are increased may be of a single type, and the control is simply performed so that the numerical data da and db are executed alternately in the forward and reverse directions by the simple numerical data dc and dd. And the amount of data created is halved, and equipment costs are reduced. However, the same applies to the case where the present mounting instruction data D2 in the first embodiment is used instead of the mounting instruction data D1. The necessary first control data D1 and execution command data D4 are stored in an external storage medium M2 and used. In this case, however, necessary data can be input and set from the operation panel.
