Assignee:
Shanklin Corporation - Ayer MA
International Classification:
B65B 51/10
US Classification:
156378
Abstract:
The problems associated with the prior art have been overcome by the present invention, which describes a tubular heating element having a more reliable and accurate temperature monitoring system. The tubular heating element has a thermocouple attached to its exterior surface, in close proximity to the cutting and sealing portion of the tubular heating element. In addition to improving the accuracy of the temperature measurement, this technique reduces electromagnetic interference caused by the interaction between the heating wire and the thermocouple.
Hinged Tubular Heater For Side Sealing Machine
US Patent:

SHANKLIN CORPORATION - Ayer MA
International Classification:
B32B 37/06, B32B 37/10, B30B 15/34
US Classification:
1565831
Abstract:
A tubular heating element which is resistant to damage caused by foreign material is disclosed. The tubular heating element is pivotably attached to the side sealing machine at its leading (upstream) edge. The trailing (downstream) edge of the tubular heating element is moved by means of a compressible force, such as an air cylinder. In this way, the air in the cylinder pushes the tubular heating element downward into the plane of the film. However, a foreign object located on the film can overcome the force of the air cylinder, thereby lifting the tubular heating element out of the path of the film.

US Classification:
533734
Abstract:
A sealing machine adapted to support a plurality of different heating/sealing/cutting mechanisms, including tubular heaters and heated cutting blades, is disclosed. The sealing machine utilizes a common interface and mounting system for all side sealers. In addition, in some embodiments, the control system within the sealing machine is adapted to monitor and control the temperature of these various mechanisms automatically so as to create proper seals.
Shrink Tunnel Control Apparatus And Method
US Patent:
2004016, Sep 2, 2004
Filed:
Mar 4, 2004
Appl. No.:
10/793403
Inventors:
Russell Christman - Dunstable MA, US
Abraham Reichental - Simpsonville SC, US
Abraham Reichental - Simpsonville SC, US
International Classification:
B65B053/02
US Classification:
053/557000
Abstract:
Control system and apparatus for controlling power consumption of a heat chamber such as a shrink tunnel. The system and apparatus of the present invention is modification to conventional systems, and takes advantage of the inherent equipment usage model in a packaging process. When the shrink wrap sealer has been idle for a predetermined duration, control circuitry in the shrink tunnel forces the tunnel to enter an energy savings mode.
Apparatus And Method For Controlling Temperature Of A Film Sealing Element
US Patent:
2004008, May 6, 2004
Filed:
Nov 1, 2002
Appl. No.:
10/286434
Inventors:
Thomas Orsini - Leominster MA, US
Russell Christman - Dunstable MA, US
Russell Christman - Dunstable MA, US
International Classification:
G01K007/02
US Classification:
374/179000
Abstract:
Apparatus and method for controlling current input to an electrical resistance element such as a seal blade. A heating sensing element such as a thermocouple monitors the temperature of a component of the sealing jaw, such as a conductive mounting member supporting the seal element. When the sensed temperature is above or below a predetermined value, the duration of the impulse current is modified until the temperature falls within a predetermined range or to a predetermined value.

International Classification:
F16P 3/08, B31B 1/00, B31F 1/00
US Classification:
192127, 493 33, 493464, 493967, 192130, 192133
Abstract:
A dunnage discharge chute includes features designed to prevent injury to an operator of a dunnage producing machine. The dunnage discharge chute includes at least one door with sensors that monitor the position of the door and output position signals. The position signals are received by a controller which outputs a control signal that disables operation of the dunnage producing machine based at least in part on a change in the position signals over a predetermined period of time. Additional sensors may detect whether the door is open beyond an upper open position, and a relay may disable operation of the dunnage producing machine immediately if the door is opened beyond the upper open position. Thus, if the operator reaches in through the door, the dunnage discharge chute will disable operation of the dunnage producing machine.
Thin Sealing Device For Side Sealing Machine
US Patent:
2013030, Nov 14, 2013

Appl. No.:
13/796428
Inventors:
Russell Christman - Dunstable MA, US
Todd Brown - Arlington MA, US
Todd Brown - Arlington MA, US
International Classification:
B31B 37/00
US Classification:
493189
Abstract:
A thin sealing device which is resistant to damage caused by foreign material is disclosed. The thin sealing device has an internal heating element. The thin sealing device has a blunt edge, which has a radius smaller than that of the heating element. A thermocouple is placed in a cavity near this blunt edge to monitor the temperature at the point of sealing. In some embodiments, the thin sealing device is pivotably attached at its leading (upstream) edge. The trailing (downstream) edge of the thin sealing device is moved by means of a compressible force, such as an air cylinder. In this way, the air in the cylinder pushes the thin sealing device downward into the plane of the film. However, a foreign object located on the film can overcome the force of the air cylinder, thereby lifting the thin sealing device out of the path of the film.

International Classification:

US Classification:
219486, 219494, 219497, 219492, 533759, 1565832
Abstract:
Control system and apparatus for controlling current input to an electrical resistance element such as a seal wire. The system and apparatus of the present invention is a closed loop feedback modification to conventional systems, and takes advantage of the inherent expansion of the seal wire as it is heated. The feedback mechanism monitors both the actual current passing through the wire, and the length of the sealing wire, and adjusts the current applied to the wire, responsive to those monitored inputs. The usage of the sealing machine is also monitored and the application and amount of current flowing to the wire is varied based on this usage.
