Description

BTM/300/1000/B/G York Tipping System

This York Tipping System is designed to lift and tip a Mail Container at a discharge height of 1000mm. The York Tipping System is a fully welded steel construction and is designed to be bolted to the floor. This York Tipping System was powered via a Helical Bevel gearbox and tipped the Mail Container to an optimum tip angle of 170 degrees. The Mail Container was loaded into lift frame and raised by rotation of the lifting carriage by the motor gearbox. As the Mail Container was tipped over to the full tip angle the mail and parcels are discharged into the conveyor hopper. The Mail Container was securely retained in the lift carriage in the fully tipped position.

Safety Guard to BS EN 14120:2015 Safety of Machinery Guards

The safety guard is constructed from 40 x 40 x 3mm box section and 3mm wire, 40mm aperture weld mesh to meet the guidelines of BS EN 14120:2015 Safety of Machinery Guards. It encloses the York Tipping System to a height of 2200mm on two sides, 1000mm at the tipping side with a pair of interlocked hinged guard doors on the fourth side. The guard doors are electrically and mechanically interlocked to prevent the York Tipping System from operating if either door is open. Additionally, the guard doors can only be opened when the lift carriage is at the full down position to prevent access whilst a load is raised. Included was additional guarding around the tipping area as well as an additional electrically interlocked safety guard door at the side of the conveyor that allowed access to retrieve any parcels that may fall out at this position and also to allow access for cleaning and maintenance to take place.

 

York Tipping System Electrical Control

The York Tipping System was fitted with an IP65 Stainless Steel Control Panel mounted on the safety guard at a convenient position to give good maintenance access under the Provision and Use of Work Equipment Regulation 1998 (PUWER). The Tipper Control included an Inverter to allow for speed control and it used a Rotary Position Sensor to stop at the full up and full down positions. It also used Over Travel Proximity Sensors which are independent of the Rotary Sensor.

The Control Panel was fitted with a PLC and HMI with the following features:-

 

  • Adjustment of the Full Up position
  • Adjustment of the Full Down position
  • A Tipper Counter
  • Selection of the Mail Sweep Mode
  • Interfacing with other equipment

The Tipper control sequence was as follows:-

  • The Mail Container is loaded into the York Tipping System and the Guard Door closed
  • There is a photo sensor inside the safety enclosure that senses that the Mail Container is loaded correctly before the container can be tipped
  • The Control On button is pressed followed by the System Start button which would cause the York Tipping System to lift and tip
  • The tipping cycle is automated so that once the full up position is reached and all of the mail is tipped out, the York Tipping System will return to the full down position to allow the empty Mail Container to be replaced
  • The guard gate interlock switch is released via a 'Guard Release' push button which allows the safety guard door to be opened
  • The empty Mail Container can then be removed and replaced with a full one and the whole cycle repeated

Performance Notes

The time to tip a Mail Container after it is loaded and the guard doors are closed, is 36 seconds, from full down, to full up and back. This includes tipping the Mail Container to a maximum angle of 170°.

Mail Container Availability

The theoretical availability of the tipper is in excess 99% based on the tipper design, the duty cycle required, the component parts used in its manufacture and the general performance of similar lifting, tipping and handling systems of our manufacture. We have assumed that the tippers are subjected to the correct maintenance regime as specified in our Technical File, that only approved spare parts will be fitted and that any corrective maintenance work is undertaken to a professional quality by technicians who are fully trained on the tippers.

Conveyor Control

The Conveyor Control was incorporated into the main control panel and included an Inverter to give speed control. The standard conveyor speed was 12.0 Meters/Minute or 200mm/Second.
