    Robot Cell Automatic Cycle Time Recording - Robot Cell

    Hello IRstuff, Sorry I missed some important detail out of the original post. I've updated it now. Yes the robot controllers log a history of one or two cycles of any given program, which can be taken from the robot pendant. There are software timers in the line software (PLC) and, in some...

    Robot Cell Automatic Cycle Time Recording - Robot Cell

    Hello all, I'm after some advice... I'm a process engineer in a welding / assembly shop with over a thousand welding and handling robots. Currently there is limited automatic cycle time recording function in the jig & robot cells which means every time we launch a new product, there are...

    Small gear used to dampen linear movement of rack.. standard parts?

    I knew I has seen them somewhere else! That's it, cassette doors. I'm sure they must still be made for other applications! I'll try the "cassette door damper" lead and see how far I get. Thanks for your help.

    Small gear used to dampen linear movement of rack.. standard parts?

    Hi all, I've seen, a few times, the use of a very small spur gear used to dampen the movement of a rack it's engaged to. I imagine the gear has a very tightly fitting rubber bushing or similar which creates high friction as it turns. I'm currently looking for one for a project where a spring...

    Mounting gears / pinions to motor shafts...

    I should have also mentioned: The geared motor im using is capable of torques up to 1N.m but the application shouldn't see torques exceed 0.5N.m

    Mounting gears / pinions to motor shafts...

    Hi all, I'm currently working on a design which uses a geared motor which is linked directly to a rack and pinion system. The motor I'm looking at has a Ø6mm shaft with a flat spot 5.5mm from one side (making it a D shape). I need a pinion to fit to the motor shaft with little chance of...

    Reciprocating autuator with time delay at extremes of stroke (required wiring)

    Sounds ideal! I'll look into that. Thanks for your help [smile]

    Reciprocating autuator with time delay at extremes of stroke (required wiring)

    Hi all, I'm currently designing a system which requires a electronic linear actuator on a reciprocating cycle. I have been informed it would be relatively easy to use a latching DPDT relay with 2 micro switches positioned at each end of the actuator's stroke. However, I require a time delay at...

    "Piggy-backing" Peltier Modules..

    Thanks for the help! I've found that the cooling power of the Peltier modules is enough with out the need to stack them. This just leaves the heating.. I need 550W of heating power constantly over 15 minutes with out going over 65°C / 66°C. I've been looking at heating cable which is used for...

    "Piggy-backing" Peltier Modules..

    Has anyone had any success with mounting two Peltier modules together in order to achieve higher temperatures on the hot side and lower temperatures on the cold? I'm currently designing a combined heating and cooling system which will ultimately be used for a batch pasteurisation process. The...

    Help with Peltier modules

    I wasn't sure what you meant by "mechanical heat pump" so did a quick google search and all I can find are vapour compression refrigeration systems.. is that what you had in mind? Heat one reservoir of exchange fluid using the condenser coils and cool another using the evapourator coils? That...

    Help with Peltier modules

    The refrigeration phase will have a significantly different "ambient" temperature to the previous heating phase. I can see how that case is considerably more complex as the "ambient" temp will be decreasing constanly. I really appreciate all the help, I think I have enough support here to buy...

    Help with Peltier modules

    - Yes it will have. Something like a rotating mixer in the centre of the container and baffle plates around the outside (which could also be used for increasing the SA for heat transfer). So this option may be feasible! To relate back to the original post, does the Delta T of the Peltier module...

    Force / Torque Release Pivot

    Brilliant idea I'll consider that! I was thinking last night and the system could also be made to work with a similar linear style of device. Like a small spring with a blow-off valve which remains rigid until a certain force is applied. Is anyone aware of any standard components which may be...

    Help with Peltier modules

    Thank you everyone for your response! I have looked at having hot and cold reservoirs and heat exchangers. My thoughts were that the hot side would be relatively cheap and easy to do but the cold side would require a complete refrigeration system (vapour compression cycle being the most...

    Help with Peltier modules

    Hi all, I'm somewhat of a novice with electronics but I am currently designing a system which needs to heat 2l of liquid up to 64°C for a short time (around 2 min) and then quickly cool it to below 7°C. Is it possibe to use peltier modules for both aspects of the system, heating first and...

    Force / Torque Release Pivot

    Hi all, I'm currently designing a system where by the following would be very useful: A pivot which remains in a "locked" position until a torque setting is over come, releasing the lock allowing the pivot to move freely. (See attached image). Has anyone come across anything like this...

    Thats great, thanks a lot! It's looking great but still a few tweeks to do tomorrow!

    Modelling Trays ...

    Haha thanks again MadMango...I did come across a couple of these tutorials but I've never used the mould toolbar before in SW...do the mould halves act as normal solids (i.e. can the upper half be removed, and the lower half be shelled from the under side?) If so I should be able to create a...

    Modelling Trays ...

    After reading a previous post on this forum I now understand that the way to go is to start with a solid block, cut in the cavities, flip the part over and shell. I need to design a tray which has a constant base (stack one way and nest the other) but the cavities must be easily changed (this...
