| A method for operating a packaging device and a packaging device are provided. Guide units which are fastened to transporter of a transport unit are moved along a plurality of supply and dispensing units. The transporter is driven by a drive axle coupled to a motor and returned via a deflection axle, the motor being coupled to a control unit. The transporter and/or the deflection axle have a plurality of markings spaced at predefined intervals, and at least one travel difference or time difference between two markings is determined. The determined difference is compared to a setpoint value and the drive axle is stopped when a deviation between the setpoint value and the determined difference exceeds a threshold value. | ||||||
| 143 | Device for indication and setting of operating tension of an endless chain strand | US15073959 | 2016-03-18 | US09738453B2 | 2017-08-22 | Tomas Cerny; Michal Chlebovec |
| A device including a chain strand where a contact point of a pivoting arm rests and slides on the chain of the chain strand. The pivoting arm is mounted on the shaft. The pivoting arm is coupled with the source of a compressive force in a form of a weight or a torsion spring. The pivoting arm is coupled with the shaft and therefore with the indicator of tension of the chain strand. The compressive force compensates for the change in resistance and lengthening of the chain when the chain conveyor is running, wherein its chain strand has been pre-tensioned by the basic pre-tensioning force induced by the tensioning device. The co-acting of the pre-tensioning force and the compressive force creates the operating tension which is not only indicated but also optimized by the device of the invention depending on a change in resistance in the chain strand. | ||||||

| 146 | Idler control system for a cable conveyor | US14290229 | 2014-05-29 | US09132965B1 | 2015-09-15 | Eric L. Nicholson |
| An improvement to cable conveyor system using a pneumatic cylinder system for keeping a cable tight is provided for preventing damage to the system if the cable stretches/fails or is too loose. The fluid cylinder/piston applies a force on the cable proportionate to the pressure that is regulated to the cylinder during normal operation of the cable conveyor system. The relative position of a magnetic switch and a magnet on a piston in the cylinder, provides a way to sense a lack of tension in the cable and shut the system down before damage is done to the conveyor. Likewise, if the cable stretches or fails, a carriage having an idler thereon, will move close enough to a proximity switch to cause the proximity switch to shut down the system. | ||||||

| 152 | System and method for controlling a conveyor belt condition monitoring system | US13119912 | 2009-09-16 | US08657105B2 | 2014-02-25 | Mick Twigger; George Mark Myers |
| A system and method are disclosed for controlling a conveyor belt condition monitoring system, and for automatically providing user alarms and system trips when sensed conditions exceed acceptable values. The system may use sensors to measure magnetic disruptions (“events”) in belt components and an algorithm may be used to monitor changes in these disruptions over time. The magnitude of these changes can then be used to predict when belt failures will occur. The system may also be used to sense when imminent failure of the belt will occur and to automatically stop the belt before failure occurs. An integrated display provides detailed information on the measured belt events and enables the user to customize alarm/trip levels and to assess problem as conditions via a virtual private network or the Internet while the belt is operating. The system is modular so that its features may be selectively integrated into existing facility-wide monitoring systems. | ||||||

| 154 | CONVEYOR BELT RIP PANELS AND BELT RIP MONITORING | US13119858 | 2009-09-16 | US20120217132A1 | 2012-08-30 | Mick Twigger; George Mark Myers |
| A conveyor belt rip monitoring system is disclosed. The system includes at least one rip panel having a conductive loop positioned in or on a conveyor belt so that the loop extends substantially across the width of the belt. The conductive loops may be formed from metallic or non-metallic materials. An RFDD chip is electrically coupled to the loop and provides a signal to an RFID interrogation unit positioned on the conveyor structure indicative of the health of the conductive loop. If a break is sensed in the loop, the RFID chip sends an appropriate signal to the interrogation unit which passes the information to a processing system. A unique resistor or diode may be included in the circuit between the chip(s) and the legs of the loop so that the interrogation unit can distinguish one leg or loop from another. If the break in the loop is determined to be due to a rip in the conveyor belt, the processing system alerts a user of the rip condition via an attached display device. For large scale rips the system may automatically stop the conveyor belt. Various embodiments of rip detection panels are also disclosed. | ||||||

| A conveyor belt monitoring system is disclosed that uses sensors to measure magnetic disruptions (“events”) in a conveyor belt which are indicative of one or more splice joints, rip panels and reinforcing cord damage. The system may comprise a plurality of sensing components, including coils or Hall Effect sensors for sensing rip panels, splices and generalized reinforcing cord damage. The system may also have RFID-based rip panels and may use RFID chips to identify various belt components. A PLC-based control system may communicate with the aforementioned components via an Ethernet link Data received by the control system is used to chart belt wear and damage trends and to provide user alarms when signal levels exceed predetermined norms. The system may stop the belt when imminent belt failure is predicted. The PLC-based control system is highly scalable and will integrate easily into existing conveyor control systems and facility-wide monitoring systems. | ||||||

| A conveyor idler includes a drum having an outer surface and an inner surface, a shaft (24) about which the drum can rotate in a forward direction, a locking mechanism for preventing the drum from rotating in a reverse direction (R) but which locking mechanism permits rotation of the drum in the forward direction, the locking mechanism having at least one wedging surface (44) fixed directly or indirectly to the drum, and a locking member (38) interposed between the wedging surface and the shaft, the locking member being rotatable about the shaft when the drum rotates in the forward direction, but when an attempt is made to rotate the drum in the reverse direction the locking member becomes releasably wedged between the wedging surface and the shaft, or a surface fixed to the shaft, thereby preventing the drum from rotating in the reverse direction. | ||||||
| 159 | TORQUE ARM ASSEMBLY FOR A BACKSTOPPING CLUTCH | US11743894 | 2007-05-03 | US20080271970A1 | 2008-11-06 | David Pearson Stoltze |
| A torque arm assembly for a backstopping clutch is provided that enables load sharing among multiple torque arm assemblies, controlled release of load on the torque arm assembly and load sensing. The torque arm assembly includes a head member that is connected to an outer race of a backstopping clutch and defines a pair of attachment points. One end of an arm member is pivotally connected to one attachment point of the head member while the other end of the arm member is connected to a stationary structure. A strut extends between the other attachment point of the head member and the arm member. Upon backstopping action by the clutch, the head member rotates slightly against the force of the strut allowing other torque arm assemblies to receive a portion of the system load. Movement of a strut seat then allows controlled release of the load tension. | ||||||

The roller safety support system further includes a frame assembly. The wall assembly is mounted to the frame assembly so that an upwardly facing surface on the wall assembly bears supportingly against the first roller in the event that the first roller becomes disengaged from the operative position. The upwardly facing surface bounds a receptacle in which the first roller is confined by the wall assembly in the event that the first roller disengages from the operative position. The receptacle has a variable configuration. | ||||||
