2. Description of the Related Art The present invention relates to surface mount technology (SMT = S
urface Mount Technology) Used as a part feeder for IC parts of equipment, the purpose of the parts feeder is to send the IC parts to the position where they are fixed one by one, and the placer picks up the IC parts and sends it to the corresponding position on the IC board, and on the surface Sticky, this kind of parts feeder type can be explained by FIG. The IC parts are installed in the installation space 91 of the feeding belt 90, the opening of the installation is sealed with a sealing tape 96, and the installation space is formed with guide wings 92, 93 on both sides of the feeding belt 90 of the installation IC parts. And the guide grooves 23 installed so as to face each other,
28 are guided by guide wings 92 and 93 to move. The feeding tape 90 of the sealing tape in which the IC parts are placed and enclosed is rounded, the feeding tape is stopped passing between the guide grooves 23 and 28, and the guide wing 93 is provided with a guide hole 95, The intermittently rotating material feeding pulley 35 and the guide hole 95 are aligned, and the feeding belt 90 is intermittently rotated to feed the material to a fixed position so that the placer can take out IC parts. Further, the sealing tape 96 is cut one by one by the intermittent rotation of the feeding belt 90, and is wound by the winding pulley 45 (see also FIG. 1). That is, the take-up pulley 45 rotates in synchronization with the material feeding pulley 35 to take up the sealing tape 96, open the installation space, and the placer takes out the IC parts. Since IC parts have various sizes, there are various feeding belts, large and small, and the width and spacing of the feeding belts vary depending on the size of the installation space. The width of the feeding belt is not an irregular width size, but a width variation having a fixed standard. At the same time, different intervals have different rotation cycles,
The rotation cycle changes according to the width of the feeding belt.

[0003] This kind of parts feeder of the prior art is:
It is composed entirely of fixed body, and the guide tank through which the feeding belt passes is installed directly on the wall of the main body. Since it is a feeding pulley, the conventional structure cannot be adjusted due to the difference in the width of the feeding belt, and the space between the feeding belt and the parts feeder is formed exclusively. Therefore, multiple parts feeders of different standards are required to correspond to different feeding belt widths, and when replacing with feeding belts of different widths during molding work, it is necessary to replace the parts feeders together.
The equipment cost of the parts feeder of multiple standards and the work of replacing the parts feeder were necessary.

[0004] As is apparent from the above, the conventional technology not only increases the equipment cost of a multi-standard parts feeder of a manufacturer, but also wastes a lot of manpower and time to replace parts feeders at the same time. The equipment was easily broken because of the increased cost and multiple replacements.

[0005]

The main object of the present invention is to provide a screw which can be driven on the body, connect the material guide plate of the guide tank with the screw, and when the drive screw rotates, a material guide is provided. The width between the material guide plates is adjusted by narrowing or expanding the plates to apply to feeding belts of different widths.

It is another object of the present invention to form a screw thread having two steps in opposite directions on the screw (left and right threads), and the two material guide plates are driven by the screw. , And synchronously narrow and widen in opposite directions.

A further object of the present invention is to provide a plurality of screws, provide interlocking parts between the screws, rotate the plurality of screws synchronously, and narrow or widen the plurality of screws of the material guide plate synchronously. By doing so, the stability and accuracy of the narrowing or widening operation is provided.

[0008]

Means for Solving the Problems A body, a saw-toothed material feeding pulley which can be engaged with a guide hole of a feeding belt, and a winding tape which is rotated in synchronization with the material feeding pulley and wound up. It consists of a take-up pulley that can be used. The feature is that two material guide plates having a guide groove are provided in the body, and a screw hole is provided in each of the two material guide plates. The receiving screw and the screw hole are joined so as to correspond to each other.
