Abstract
An automated bag closure machine includes a mechanical bag closure advancement assembly and a mechanical bag closure breakoff assembly, wherein operation and timing of the mechanical bag closure breakoff assembly is governed by a cam and/or a manual pull-knob. The machine may include optical sensors configured to monitor the passage of bags through the machine and a fiber optic system to monitor the passage of bag closures through the machine. The machine may be mounted to other systems in a manner that allows fully fluid movement or adjustment of its position and orientation. The machine may have remote communications functionality.
Claims29
A system for applying bag closures from an elongate strip of connected bag closures to bags as the bags travel along a path with respect to the system, comprising:
- an optical sensor located at a first side of the path;
- and
- an optical reflector located at a second side of the path opposite to the first side of the path, wherein the optical sensor and the optical reflector face one another such that light emitted by the optical sensor is reflected by the optical reflector toward the optical sensor;
- and
- a breakoff lever configured to break a single bag closure off an end of the elongate strip of connected bag closures during movement of the breakoff lever;
- a motor;
- a cam;
- a clutch configured to engage the cam to the motor and to disengage the cam from the motor, wherein the cam is mechanically coupled to the breakoff lever such that rotation of the cam controls the movement of the breakoff lever;
- a driven shaft, wherein the cam is coupled to the driven shaft and the clutch is configured to engage the driven shaft to the motor to engage the cam to the motor and to disengage the driven shaft from the motor to disengage the cam from the motor;
- a guide plate including a slot and an opening, wherein the slot is configured to receive the elongate strip of connected bag closures and the opening extends through the guide plate and is open to the slot;
- and
- a fiber optic cable, wherein a terminal distal end of the fiber optical cable faces toward and through the opening and faces toward and through the slot.
A system for applying bag closures from an elongate strip of connected bag closures to bags as the bags travel along a path with respect to the system, comprising:
- an optical sensor located at a first side of the path;
- and
- an optical reflector located at a second side of the path opposite to the first side of the path, wherein the optical sensor and the optical reflector face one another such that light emitted by the optical sensor is reflected by the optical reflector toward the optical sensor;
- a mechanical bag closure breakoff assembly including a breakoff lever configured to break a single bag closure off an end of the elongate strip of connected bag closures during movement of the breakoff lever;
