Description

  The present invention relates to a cap alignment and supply device that is optimal for aligning caps having pull tabs and supplying them at high speed.

Conventionally, various types of cap alignment supply devices for aligning and supplying caps having pull tabs are known.
For example, a rotating disk (rotary disk 6) that is driven to rotate by placing a number of caps (container lids 32) having pull tabs (gripping pieces 32a), and an outer peripheral side of the upper part of the rotating disk (rotary disk 6) A cylindrical cap alignment guide (side wall 26, restricting member 18) having a cap outlet part (exit part 22) in part, and a cap discharge mechanism provided at the cap outlet part (exit part 22). The cap (container lid 32) having the pull tab (grip piece 32a) is accelerated in the tangential direction by receiving a force from the friction force on the rotating disk (the rotating disk 6), and is rotated by the centrifugal force (rotating disk). The board 6) slides on the cap alignment guide (side wall 26, restricting member 18) side, and is discharged from the cap outlet portion (exit portion 22) to the alignment discharge portion (discharge chute 24) and supplied to the outside. Cap alignment Feeding device is known (e.g., see Patent Document 1 and the like.).

In such a cap alignment supply device, smoothly discharging the cap from the cap outlet portion to the alignment discharge portion greatly affects the continuity and supply speed of the cap.
However, in the known cap aligning and supplying apparatus as described above, the cap is speeded only by the rotating disk in the tangential direction of the cap aligning guide, and no normal speed component is given, whereas the aligned discharge is performed. The portion is configured to be guided and discharged in the normal direction of the cap alignment guide.
For this reason, it is necessary to provide a large normal velocity component for discharging the cap by means such as jetting air in the normal direction near the cap outlet.

JP 58-6813 A (all pages, all figures)

However, in the cap alignment supply device for aligning and supplying caps having pull tabs as described in Patent Document 1, the cap alignment guide is partially interrupted to pass the pull tabs at the cap outlet. Therefore, when a normal velocity component is applied to the aligned caps, there is a problem that even the unaligned caps are discharged to the aligned discharge unit, and this causes a problem of clogging. It was.
In addition, in order to increase the speed, it is necessary to increase the speed component in the normal direction, so that it is necessary to increase the size of the apparatus. Further, this causes further unaligned cap discharge and clogging. Because of the increase, there is a problem that it is difficult to increase the speed.
In addition, it is conceivable to intermittently eject air in the reverse direction (from the cap guide member to the inner circumferential direction of the rotating disk) at regular intervals to prevent clogging, but the efficiency for the ejection time decreases, There was a problem that the continuity of the supplied cap was hindered.
In addition, there is a problem that a mechanism for intermittent jetting is required and the apparatus becomes complicated.

  Therefore, the present invention aims to solve the problems of the known cap alignment and supply apparatus as described above, and guarantees the continuity of discharged caps without complicating or increasing the size of the configuration. It is another object of the present invention to provide a cap alignment and supply device that can increase the discharge speed and increase the cap supply capability, and can reliably align the caps discharged at high speed.
