Therefore please note that the terms used in the text stand for the corresponding explanations listed below. · Equipment “Equipment” can mean an individual unit, a machine or an installation. personnel · Operating The “operating personnel” are persons operating the equipment on their own responsibility or according to instructions (minimum age: 16).
SSK-3 1.3. For your safety is absolutely necessary that you observe the operating instructions for the · Itcorresponding conveying system. device is intended exclusively for conveying plastic granules and regrind. · The Any other usage is not permitted. · This device is not suitable for processing foods. beginning maintenance work, set all compressed air piping on the device · Before at zero pressure.
SSK-3 2. Installation instructions » L These installation instructions are intended for persons with skills in electrical and mechanical areas due to their training, experience and received instructions. Personnel using these installation instructions must be instructed in the regulations for the prevention of accidents, the operating conditions and safety regulations and their implementation. Ensure in each case that the personnel are informed.
SSK-3 2.1. Transport For transport, only the appropriate lifting gear should be used (e.g. fork lift or workshop crane). » Observe the carrying capacity of the lifting gear. Observe the safety instructions for the handling of lifting gear. 2.2. Set-up The arrangement of the hopper loaders may vary depending on the type of device to be conveyed on and the material used. Fastening onto fixed machine throats is provided by means of strap retainers.
SSK-3 Mount the hopper loader in such a way that the outlet flap swings in a right-hand angle to the direction of machine movement. Please check during assembly that the admissible bearing loads are not exceeded. Please check that all connecting points are tight to ensure that the conveying performance is not impaired.
SSK-3 2.3. Compressed-air supply (only with compressed-air valves) For operating the control valves, a compressed-air supply is necessary. Check compressed-air piping for correct installation and assembly. Check fittings, length and quality of the hose connections for agreement with requirements. The operating pressure is 5-6 bar (72.52-87.02 PSI) (system overpressure). Check the compressed-air supplied by the plant’s supply network. Maintenance unit Adjust compressed-air pressure to 5-6 bar (72.52-87.
SSK-3 2.4. Electrical connection » The electrical connection may only be carried out by trained personnel. Other persons are not permitted to carry out the electrical connection. The rules of the local electricity board must be observed. Before beginning the electrical connection, make sure that the mains voltage and the power frequency are in accordance with the data on the name plate of the device. All work may only be carried out when the unit is at zero voltage and at zero pressure.

SSK-3 3. Functional description The conveyor hopper is used for the automatic conveyance of freely flowing plastic granules. The hopper can only function in connection with a vacuum conveyor plant. The hopper works without a filter. Depending on the type of valve, the shut-off valve of the vacuum line is operated with compressed air (compressed-air valve) or with the vacuum air (diaphragm valve).
SSK-3 4. Maintenance » This chapter is intended for persons with skills in electrical and mechanical areas due to their training, experience and received instructions. Personnel using the instructions in this chapter must be instructed of the regulations for the prevention of accidents, the operating conditions and safety regulations and their implementation. Ensure in each case that the personnel are informed accordingly. For maintenance work taking place at heights of over approx. 1828.8 mm (6 ft.
SSK-3 L Disconnect the equipment from mains supply before starting maintenance procedures to ensure that it cannot be switched on unintentionally. Depressurize all compressed air piping of the equipment before starting maintenance work. F Please observe the maintenance intervals. Before starting maintenance work, clean the equipment of oil, fuel or lubricants.
SSK-3 4.1. Maintenance intervals Daily: Check warning signs on equipment for good legibility and completeness. With compressed-air valve: check the oil level in the oiler empty the water separator check the operating pressure in the factory ductwork system (max. 6 bar (87.
SSK-3 4.2. Disassembling the hopper & Individual hoppers can also be maintained during operation. However, Sterling recommends that you switch off the conveying plant for all types of work on the hopper. Wait until the conveying procedure has stopped. Switch off the hopper by means of the on/off switch (A) on the connection housing. Disassemble the vacuum line on the hopper. Close the disassembled vacuum line so that the vacuum for the active hopper-loaders does not break down.
SSK-3 Depressurize the compressed-air line to the hopper (only with compressed-air valve). Disassemble the material line on the lateral inlet of the hopper. Remove the connecting plug (B) “conveyor control” on the connection housing of the hopper. SM3-610 Disassemble the hopper.
SSK-3 4.2.1. Replace the sealing rings Nonreturn valve Open the toggle-type fasteners between the hopper lid and the hopper loader. Fold the hopper lid upwards. Draw the old sealing ring off the nozzle (A). Install the new sealing ring. Observe the direction of installation (B). A Close the hopper lid. Close the toggle-type fasteners. B Install the hopper.
SSK-3 Outlet flap Draw the old sealing ring (A) off the nozzle of the material outlet. Install the new sealing ring (A). F Observe the direction of installation (B). Install the hopper.
SSK-3 4.2.2. Adjust the flap switch Remove the connecting plug “flap switch” from the connection housing of the hopper. Connect an ohmmeter to PINS 2 and 3 of the connecting plug “flap switch”. Release the nuts (A) of the flap switch (B) until the support can be displaced. Open the outlet flap (C) so far that the front tip of the outlet flap is approx. 30 mm (1.18 inches) away from the sealing surface. Displace the flap switch (B) until the contact of the magnet switch is closed.
SSK-3 4.2.3. Cleaning the hopper Open the toggle-type fasteners between the hopper lid and the hopper loader. Fold the hopper lid upwards. A Check the sieve within the hopper lid (A) for material residue. For cleaning, disassemble the sieve: Pull the sieve out of the sealing ring. Clean the sieve by means of compressed-air. Install the sieve. B C D Check the sieve for proper fit. Clean the hopper loader by means of a vacuum cleaner. Close the hopper lid. Close the toggle-type fasteners.
