This symbol indicates that serious injury is possible if the corresponding instructions, regulations or warnings are not observed.
SSK-30 1.2. Explanations and information Various terms and designations are used frequently in these operating instructions to ensure clarity. Therefore please note that the terms used in the text stand for the corresponding explanations listed below. ment · Equip “Equipment” can mean an individual unit, a machine or an installation. erating personnel · Op The “operating personnel” are persons operating the equipment on their own responsibility or according to instructions (minimum age: 16).
SSK-30 1.3. For your safety absolutely necessary that you observe the operating instructions for the cor· Itreisspond ing 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. fore beginning maintenance work, set all compressed air piping on the device · Be at zero pressure.
SSK-30 2. Installation instructions » 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-30 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-30 Please check that all connecting points are tight to ensure that the conveying performance is not impaired. It should moreover be observed, particularly if custom produced connecting parts are used, that the material discharged from the hopper loader must neither get into the open nor must it clog the filter surfaces (observe angle of repose!).
SSK-30 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-30 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. SM3-626 All work may only be carried out when the unit is at zero voltage and at zero pressure.

SSK-30 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-30 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. 1829 mm. (6 ft.
SSK-30 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-30 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.
SSK-30 4.2. Servicing the hopper loader & 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. Switch off the hopper by means of the on/off switch (A) on the connection housing. Wait until the conveying procedure has stopped. Disassemble the vacuum line on the hopper. SM3-626 Close the disassembled vacuum line so that the vacuum for the active hopper-loaders does not break down.
SSK-30 Depressurise 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. SM3-626 Disassemble the hopper.
SSK-30 4.2.1. Replacing the nonreturn valve sealing ring Open the tension ring (A). Remove the hopper lid. Draw the old sealing ring off the nozzle (B). Install the new sealing ring. Observe the direction of installation (C). A C Mount the hopper lid. Close the tension ring (A). Install the hopper loader.
SSK-30 4.2.2. Replacing the outlet flap sealing Remove the connecting plug “flap switch” (A) from the connection housing of the hopper. Remove the tension ring (B) and the sealing ring on the hopper loader. Remove the upper part of the hopper loader (C) from the lower part of the hopper loader (D). Remove the old outlet flap sealing (E) and the adhesive from the slot. Check that no sticky rests are left behind! Glue the new outlet flap sealing into the slot. Use a suitable adhesive (e.g. Pattex).
SSK-30 Install the upper part of the hopper loader (C) on the lower part of the hopper loader (D). Install the sealing ring and the tension ring (B) on the hopper loader. Connect the connecting plug “flap switch” (A) to the connection housing of the hopper. Install the hopper loader.
SSK-30 4.2.3. 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. 50 ± 2 mm (1.97 ± 0.18 in.) away from the sealing surface. Displace the flap switch (B) until the contact of the magnet switch is closed.
SSK-30 4.2.4. Cleaning the hopper loader Open the tension ring (A). Remove the hopper loader lid. Check the sieve (B) within the hopper for material residue. For cleaning, disassemble the hopper: turn the hopper approx. 1/2 rotation counterclockwise. Clean the sieve by means of compressed-air. Install the hopper: turn the hopper approx. 1/2 rotation clockwise. Check the hopper for proper fit. Clean the hopper loader by means of a vacuum cleaner. Mount the hopper loader lid. Close the tension ring (A).
