PLC Ladder Program Example for Detect the size of part and distribute it

PLC Ladder Program Example for Detect the size of each part and distribute it to the specified place.



Control Objective


Detect the size of each part and distribute it to the specified place.





Control Specifications


The following operation should be performed in this unit.


Study the required specifications and then create the program and confirm the operation.


  1)     When [PB1] (X20) on the operation panel is pressed, Supply command(Y0) for the hopper is turned ON.
When [PB1] (X20) is released, Supply command (Y0) is turned OFF. When Supply command(Y0) is turned ON, the robot supplies a part.


  2)     When [SW1] (X24) on the operation panel is turned ON, the conveyors move forward.
When [SW1] (X24) is turned OFF, the conveyors stop.



  3)     Large, medium and small parts on the conveyors are sorted by the input of sensors Upper (X0), Middle(X1) and Lower (X2) and carried to the specified trays.


• Large part
:
Pushed to the lower conveyor and carried to the right tray.
• Medium part
:
Moved to the tray by the robot.
• Small part
:
Pushed to the lower conveyor and carried to the left tray.

  4)     When the sensor Detect part (X3) is turned ON, the conveyor stops and a large or small part is pushed to the lower conveyor.

Note:
When the actuating command for the pusher is set ON, it extends completely.
When the actuating command is set OFF, the pusher retracts completely.
  5)     When Part on table (X5)is turned ON in the robot, Unload command (Y4) is set ON.
When Robot operation finished (X6) is turned ON (it is ON when a part is placed on the tray), Unload command (Y4) is set OFF.


  6)     While [SW2] (X25) on the operation panel is ON, a new part is to be automatically supplied at the following time.

•
When the robot starts to carry a medium part
•
When a small or large part is put into a tray



PLC Ladder Program Description:


In this exercise, the size of parts carried on the conveyor is to be sorted using three sensors shown on the table.

Part size
Upper (X0)
Medium (X1)
Lower (X2)
Large
ON
ON
ON
Medium
OFF
ON
ON
Small
OFF
OFF
ON

The programs for this exercise can be classified into the following controls.

1)
Program to supply the part from the hopper
2)
Program to detect part size and store the data
3)
Program to operate the conveyors
4)
Program to detect a part to be pushed to the lower conveyor and to stop the conveyor
5)
Program to push a part to the lower conveyor
6)
Program to carry a medium part to the robot and to move it to the tray
7)
Program to move the lower conveyor forward or backward according to the detected part size
8)
Program to reset the part size data after the specified processes have finished and to supply the next part depending on the switch condition


Turn ON [SW1] (X24) on the operation panel.

Result>>The conveyor moves to the right


Press [PB1] (X20) on the operation panel.

Result>>A part is supplied from the hopper


Sorting part size

• Large part
:
Pushed to the lower conveyor and put on the right tray.
• Medium part
:
Moved into the tray by the robot on the upper conveyor.
• Small part
:
Pushed to the lower conveyor and put on the left tray.

              Operation while [SW2] (X25) on the operation panel is ON

Result >>The next part is supplied from the hopper when the robot starts to move a medium part or when a small or large part is put on a tray.

Perhitungan & Cara Merubah Kumparan Blender Dari 220 V Menjadi 12 V

          Seperti yang telah dijelaskan pada buku “menggulung motor listrik arus bolak-balik, servis peralatan listrik rumah tangga kelompok penggerak dan perbaikan peralatan listrik pertukangan”, bahwa motor penggerak yang digunakan pada perlatan listrik rumah tangga dan pertukangan seperti blender, mixer, bor tembak, gerinda dsb menggunakan jenis motor universal. Motor universal adalah jenis motor listrik yang dapat disuplai dengan sumber listrik arus bolak-balik (AC) dan arus searah (DC). Jadi peralatan-peralatan listrik rumah tangga dan pertukangan tersebut yang biasanya kita suplai dengan sumber listrik AC dari PLN atau Genset sebesar 220 V sebenarnya dapat juga kita suplai dengan sumber listrik DC yang tentunya tegangan juga harus sama yakni 220 V.           Yang menjadi permasalahan bagaimana kalau peralatan listrik rumah tangga atau pertukangan tersebut, sebagai contoh misalkan blender yang ingin digunakan atau dioperasikan pada tempat yang tidak terdapat sumber listrik PLN ata

Testhead

4.3         Testhead The testhead is that portion of the tester that supports the PIN, ASRU and Controller cards.   The testhead is divided into two BANKS and each BANK is divided into two MODULES, see figure 2 below.  Bank 1 contains modules 0 and 1, bank 2 contains modules 2 and 3.  The test fixtures are placed on the banks of the tester and locked down for board testing.  The testhead cards interface to the test fixture through the spring loaded pogo pin “nails” at the top edge on each of these card types. 4.4       Support Bay The support bay is a stand-alone cabinet that houses the power supplies for the Unit Under Test.  This bay also houses the test station power distribution unit and test station controller on earlier models. 4.5       Emergency Shutdown Switch The emergency shutdown switch is the large red button located at the lower left corner on the front of the testhead.  It turns off all AC power to the testhead, and is equivalent to turning off the m

Kelebihan dan Kekurangan Saluran Listrik Jenis Saluran Udara dan Saluran Bawah Tanah

Berdasarkan pemasangannya,   saluran distribusi dibagi menjadi dua kategori, yaitu : saluran udara (overhead line) merupakan sistem penyaluran tenaga listrik melalui kawat penghantar yang ditompang pada tiang listrik. Sedangkan saluran bawah tanah (underground cable) merupakan sistem penyaluran tenaga listrik melalui kabel-kabel yang ditanamkan di dalam tanah. 1.    Saluran Bawah Tanah (Underground Lines) Saluran distribusi yang menyalurkan energi listrik melalui kabel yang ditanam didalam tanah. Kategori saluran distribusi seperti ini adalah yang favorite untuk pemasangan di dalam kota, karena berada didalam tanah, maka tidak mengganggu keindahan kota dan juga tidak mudah terjadi gangguan akibat kondisi cuaca atau kondisi alam. Namun juga memilik kekurangan, yaitu mahalnya biaya investasi dan sulitnya menentukan titik gangguan dan perbaikannya. Kedua cara penyaluran memiliki keuntungan dan kerugian masing-masing. Keuntungan yang dapat diperoleh dari suatu jaringan bawah tanah adalah
