    摘要: The present invention describes an improved grip belt drive system for use in sealing machines used to wrap articles in thermoplastic film. Briefly, a timing belt is used in place of the traditional flat or V belt. The presence of teeth on the pulleys, coupled with the use of a timing belt eliminates the possibility of slippage between the belt and the pulleys. To protect the system in the case of a film jam or misplaced article, a torque-limiting mechanism is included, which disengages the drive system if there is excessive counterforce. Furthermore, the outer surface of timing belt contains a pattern, which when mated with a second belt having the same or a complementary pattern, meshes in such a way so that the two belts are positively locked in both the longitudinal and transverse directions.

    摘要: An operating mechanism for the seal jaw in a package wrapping machine has an operating arm with means along its length to alter the length of the arm between two finite positions. The arrangement is such that the operating arm for the sealing jaw in the package wrapping machine can be controlled so that it can open to a higher position for large packages and yet also open to a shorter position for less high packages, thus, speeding up the operation of the machine so that it can accept a greater number of packages for any given length of time.

    摘要: A seal wire heat control system adapted to record in memory the immediate history of the operation of the seal wire and to adjust the time duration of the application of voltage to the seal wire in accordance with a predetermined program. The application of heat is controlled according to the running history of the machine. At start up, a relatively long pulse of power is sent through the wire to make a seal for a predetermined number of times. When the count is reached, an intermediate pulse is provided to the wire for a predetermined number of times. When this count is reached, a short pulse is provided to the wire. A reset timer monitors idle time. If no seal is executed after a predetermined time, the entire system, including counters, resets to prepare for delivery of a long pulse to the wire. A safety timer is also provided for limiting the duration of power to the wire within the wire's safety threshold value.

    摘要: A form fill seal type wrapping machine uses equal speed conveyors which are start/stop controlled to accept randomly fed packages and uniformly space them for wrapping and sealing in a roll fed wrapping material such as thermoplastic film. Different length packages can be wrapped without adjustment. One embodiment uses a traveling transverse seal mechanism so the machine can run continuously. Machine speed is enhanced by controlling dwell time for the transverse seal and time of travel for the transverse seal mechanism to be no longer than required to make the seal. A fast return mechanism for the transverse seal mechanism operates at a speed independent of machine speed.

    摘要: A pneumatic-electromagnetic latch is disclosed as applied to bring the sealing jaws of an L-sealer into pressure engagement without impact. An electromagnet mounted on a piston rod of a pneumatic actuator attracts and retains an armature attached to the sealing jaws when the jaws are brought close to the sealing bed. The cylinder of the actuator is attached to the frame and when actuated it draws the sealing jaws into smooth pressure contact with the sealing bed. Upon deenergization of the electromagnet the jaws are released to open for the next sealing cycle and the release of fluid pressure in the actuator extends the piston rod to position for the next operation.
