Abstract

An intermittent feed system for intermittently feeding a plurality of works in two rows in a predetermined direction has a pair of guide rails which extend in the predetermined direction in parallel to each other and spaced from each other in the direction of their widths. A single endless belt is disposed below the space between the guide rails and extends in the predetermined direction. A plurality of attachments are fixed to the endless belt at regular intervals to move together with the endless belt in the predetermined direction. Each attachment has a vertical base portion which projects upward through the space between the guide rails and a pair of arm portions which transversely project in opposite directions above the respective guide rails so that when the endless belt moves in the predetermined direction, each arm portion pushes the work placed on the corresponding guide rail in the predetermined direction along the guide rail.

Claims

1. An intermittent feed system for intermittently feeding a plurality of works in two rows in a predetermined direction, comprising:

a pair of guide rails which extend in the predetermined direction in parallel to each other and spaced from each other in the direction of their widths,

a single endless belt which is disposed below the space between the guide rails and extends in the predetermined direction, and

a plurality of attachments fixed to the endless belt at regular intervals to move together with the endless belt in the predetermined direction, each attachment comprising a vertical base portion which projects upward through the space between the guide rails and a pair of arm portions which transversely project in opposite directions above the respective guide rails so that when the endless belt moves in the predetermined direction, each arm portion pushes the work placed on the corresponding guide rail in the predetermined direction along the guide rail wherein each of said attachments is fixed to the endless belt by way of a profile which is fixed to the endless belt and is provided with a horizontal through hole, and said base portion of the attachment has a pair of leg portions which are spaced from each other and are provided with through holes extending horizontally in alignment with each other, the base portion being positioned on the endless belt so that the leg portions are on opposite sides of the profile with the through holes of the leg portions and the profile in alignment with each other and fixed to the profile by means of a pin member which is inserted into the through holes, the distance between the through holes of the leg portions and the lower surface of the leg portions being slightly larger than the distance between the through hole of the profile and the upper surface of the endless belt so that the leg portions are pressed against the endless belt when the pin member is inserted into the through holes.

2. An intermittent feed system as defined in claim 1 in which the space between the guide rails is smaller than the width of said endless belt.
