Problems solved by technology

Therefore, when the distance between the engaging holes engaged with the two adjacent sprockets in the conveying direction is shorter than the normal distance, there is a problem that the carrier tape is pulled by the push-in sprockets and When the components stored in the carrier tape cannot be accurately supplied to the supply position

other Embodiment approach

[0096] In the above-described embodiment, such as Figure 7 , Figure 8 As shown, by setting the tooth thickness dimension b of the second engaging protrusion 62a to be smaller than the tooth thickness dimension a of the first engaging protrusion 61a, the cross-sectional area of ​​the second engaging protrusion 62a is set to be larger than that of the first engaging protrusion. The cross-sectional area of ​​the engagement protrusion 61a is small. However, even by setting the tooth width dimension d of the second engaging protrusion 62a to be smaller than the tooth width dimension c of the first engaging protrusion 61a, the cross-sectional area of ​​the second engaging protrusion 62a is set to be larger than that of the first engaging protrusion 61a. The embodiment with a small cross-sectional area of ​​the engaging protrusion 61a is not affected. In such an embodiment, even if a gap is generated between the second engaging protrusion 62a and the engaging hole 901b, and the dist...

Abstract

The purpose of the present invention is to provide a non-splicing feeder provided with a plurality of sprockets in a transport direction, said non-splicing feeder accurately supplying components held in a carrier tape to a supply position. The feeder comprises: a main unit (21b); a first sprocket (61) which is rotatably disposed at a supply position (21a) of the main unit (21b), and upon which first engaging projections (61a) are formed; and a second sprocket (62) which is rotatably disposed on the main unit (21b) at a transport direction upstream side of a carrier tape (900) relative to the first sprocket (61), and upon which second engaging projections (62a) are formed. Tooth-thickness dimensions of the second engaging projections (62a) are set to be smaller than tooth-thickness dimensions of the first engaging projections (61a).

Description

Technical field [0001] The present invention relates to a feeder for feeding a carrier tape containing components. Background technique [0002] Hitherto, as shown in Patent Document 1, there has been proposed a non-lap feeder that supplies components stored in a carrier tape to a component mounting device without performing overlap work. Such a feeder is provided with a sprocket engaged with an engagement hole formed in the carrier tape, and the carrier tape is fed by rotating the sprocket. In the lapless feeder shown in Patent Document 1, a drive sprocket is provided in the vicinity of the supply position, and a press-fit sprocket is provided adjacent to the upstream side of the drive sprocket in the conveying direction. [0003] Patent Document 1: Japanese Patent Application Publication No. 2011-77096 ( Figure 4 Reference) Summary of the invention [0004] In the lapless feeder shown in Patent Document 1, two sprockets, a drive sprocket and a press-fit sprocket, are provided ad...
