Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a direction alignment device for aligning bottle caps formed in a pot shape so that their openings face upward.

Conventional orientation alignment devices for bottle caps use a rotary parts feeder to line up the bottle caps in a line and transport them through a gate that allows the bottle caps to pass through only when they are in an upward or downward orientation. Accordingly, a method is adopted in which the postures of bottle caps are aligned in an upward or downward direction, and then bottle caps in a downward posture are excluded from a row of bottle caps in an upward posture.

However, this product uses a rotating body that aligns the bottle caps in a fixed direction, and a gate that allows passage only when the bottle caps are facing up or down, so the diameter and/or height dimensions of the bottle caps change. In addition to requiring replacement of the rotating body in the gate and parts feeder accordingly, the bottle caps could only be aligned in a single line, which was extremely inefficient.

The present invention uses a feed pan that reciprocates diagonally upward to align the bottle caps so that their openings face upward, thereby solving the above-mentioned drawbacks of the prior art.

For this reason, the present invention provides a feed pan supported substantially horizontally, with one side formed as a bottle cap delivery section and the other side formed as a bottle cap supply section, and the feed pan is directed toward the bottle cap delivery section. The feed pan is configured to reciprocate in an upward diagonal direction, and a plurality of guide bodies extending from the bottle cap supply section to the bottle cap delivery section are provided in parallel on the upper surface of the feed pan, and a plurality of guide bodies extending from the bottle cap supply section to the bottle cap delivery section are provided in parallel. A feed groove is formed extending from the bottle cap supply section to the bottle cap delivery section, and the longitudinal side of each guide body into the feed groove is aligned in the longitudinal direction of the feed groove with respect to the upper surface of the feed pan. The guide surface is inclined so that the cross-sectional shape in the direction perpendicular to the direction is a trapezoidal shape that expands upward, and on the upper surface of the feed pan in the feed groove, there is a guide body, which is generally referred to as a guide body, at a midway point in the longitudinal direction of the guide body. Parallel extending protrusions are protrudingly provided, and the tip portion of the longitudinally inclined guide surface of each guide body on the bottle cap feeding section side is formed so that the width of the feed groove between each guide body is the same as that of the bottle cap. The structure is characterized in that it is formed into an outwardly inclined surface that is bent outward so as to gradually widen toward the lid delivery section.

The present invention will be explained below with reference to drawings of embodiments. In the drawings, 1 is a machine base, 2 is a machine frame attached to the upper surface of the machine base 1 via a vibration-proof rubber 3, and 4 is the machine frame 2.

On the other hand, the feed grooves 16 are formed with inclined guide surfaces 17, 17 which are inclined so that the cross-sectional shape in the direction perpendicular to the longitudinal direction is a trapezoidal shape that spreads upward, and the upper surface of the feed pan 6 in each of the feed grooves 16 is provided with: A protrusion 18 extending substantially parallel to the guide body 15 is provided at a midway position in the longitudinal direction of the guide body 15, while an upper surface of the tip of each guide body 15 on the side of the bottle cap delivery section 8 is The bottle cap delivery section 8 of the guide body 15 is formed into a downwardly sloped surface 19 that gradually becomes lower toward the bottle cap delivery section 8, and among the longitudinally inclined guide surfaces 17, 17 of each guide body, the bottle cap delivery section 8 of the guide body 15 The portion at the tip of the side is formed into an outwardly inclined surface 20, 20 bent outward so that the width of the feeding groove 16 between each guide body 15 gradually widens toward the bottle lid feeding portion 8. It is something.

In this configuration, the bottle cap A from the bottle cap hopper 4 is supplied to the bottle cap supply section 9 in the feed pan 6, and is passed through the feed groove 16 in the diagonally upward direction toward the bottle cap delivery section 8 in the feed pan 6. By reciprocating rocking, the bottles are sequentially sent to the bottle cap delivery section 8, and during this feeding, they are aligned so that the openings face upward.

That is, from the bottle lid hopper 4 to the feed pan 6
The bottle cap A supplied to the bottle cap supply section 9 falls into each feed groove 16 on the upper surface of the feed pan 6, but at the time of this fall, there is a mark A1 in the drawing.
As shown in , the top plate is facing downward and the opening is facing upward, and the guide body 15 is caught in the middle of the inclined guide surfaces 17, 17 in the feed groove 16. A bottle lid that enters into the feed groove 16 in a horizontal position and with its opening leaning against one of the two inclined guide surfaces 17, 17 as shown by reference numeral A2. ,
As shown by symbol A3, the double inclined guide surfaces 17, 17 are placed in a posture with the top plate facing upward and the opening facing downward.
A bottle cap that enters the feed groove 16 while being caught in the middle of the bottle, a bottle cap that enters the feed groove 16 in an upright position as shown by the symbol A4, and a bottle lid that enters the feed groove 16 in an upright position as shown by the symbol A4, and furthermore, There is a bottle lid that enters the feed groove 16 with the top plate leaning against one of the two inclined guide surfaces 17, 17.

Each of these bottle caps is sequentially transferred toward the bottle cap delivery section 8 by the reciprocating swing of the feed pan 6, but among the bottle caps, the bottle cap with reference numeral A1 is
