Abstract
A splicer machine for feeding strips of closures or clips. The clips formed of flat plastic material, and for receiving portions of flexible bags. More specifically, the automated handling of strips of such clips, where strips of the clips are held together by interlocking portions of the clips.
Claims17
A clip-strip feed splicer, the splicer including:
- a first clip-roll, having a continuous first clip-strip, received on a first spool and a second clip-roll, having a continuous second clip-strip received on a second spool, with the first spool and the second spool mounted to a lever, and the lever having a first lobe and a second lobe, the first spool mounted to the first lobe and the second spool mounted to the second lobe of the lever, and the lever rotatably mounted to a lever pivot on a lever arm, with the first spool and the second spool alternate-able from a feed position to a pre-stage position on the lever arm;
- the first clip strip and the second clip strip including a multiple of interlock-able clips, the multiple of interlock-able clips removably interlock-able together in series, with each interlockable clip of the first clip strip and the second clip strip having a first interlock element and a second interlock element, the first interlock element interlockable to the second interlockable element of a neighboring interlockable clip;
- and
- the first clip-strip of the first spool initially in the feed position and the first clip-strip feed-able past a clamp mechanism, the second clip-roll initially queued-up in the pre-stage position, the clamp mechanism including a first block clamp-able against a second block, with the second interlock element trailing from the first clip-roll and the first interlock element leading from the second clip-roll positioned on the first block, and with the first block clamp-able with the second block to interlock the second interlock element of the first clip-roll to the first interlock element of the second clip-roll.

A method for a clip-strip feed splicer, including the steps of:
- a) mounting a first clip-roll on a first lobe of a lever, the first clip roll having a continuous first clip-strip received on a first spool, the first clip strip including a multiple of interlock-able clips, the multiple of interlock-able clips removably interlock-able together in series, with each interlockable clip of the first clip strip having a first interlock element and a second interlock element, the first interlock element interlockable to the second interlockable element of a neighboring interlockable clip;
- b) mounting a second clip-roll on a second lobe of the lever, the second clip-roll having a continuous second clip-strip received on a second spool, the second clip strip including a multiple of interlock-able clips, the multiple of interlock-able clips removably interlock-able together in series, with each interlockable clip of the second clip strip also having the first interlock element and the second interlock element;
- c) rotatably mounting the lever to a lever pivot on a lever arm, with the first spool and the second spool alternate-able from a feed position to a pre-stage position on the lever arm;
- d) feeding the first clip-strip past a clamp mechanism, the first clip-strip of the first spool initially in the feed position, and the clamp mechanism including a first block clamp-able against a second block to interlock to the first clip-roll to the second clip-roll, and the second clip-roll initially queued-up in the pre-stage position, with the first interlock element of the second clip-roll leading from the second clip-roll and positioned on the first block;
- e) rotating the lever to move the second clip roll on the second spool to the feed position, and the first spool to the pre-stage position;
- f) pulling the clip-strip with the pair of feed-rolls through the clamp mechanism feeding the first clip-roll into the splicer from the feed position;
- g) queuing the second clip-roll in the pre-stage position, with the first interlock element leading from the second clip-roll and positioned on the first block and waiting for a last clip from the first clip-roll to move into a clamping position with the second block;
- h) feeding the clip-strip from the first clip-roll from the feed position into the clamp mechanism;
- i) mounting the first interlock element in the first block from the second spool;
- j) aligning an out-going second interlock element of the clip-strip from the first clip-roll to an in-coming first interlock element of the clip-strip from the second clip-roll;
- k) clamping the first block to the second block to interlock the out-going second interlock element from the first clip-roll to the in-coming first interlock element of the second clip-roll;
- and
- l) resuming the pulling of the clip-strips from the second clip-roll with the lever rotating to the feed position.
