Description
Technical field
The present invention relates to moulding conveying technology fields, especially conveyer belt code control system.
Background technique
In injection workshop, multistation injection moulds equipment injection molded plastic parts simultaneously, is then put by manipulator clamping plastic part defeated
It send and takes.Since conveying tape travel rhythm and the injection molding rhythm of all injection molding machines can not be in step with completely, lead to rear manipulator
Plastic part may be launched to formerly launching on the conveyer belt position for having plastic part, plastic part is caused to collide.
Currently in order to solving the problems, such as this, Some Enterprises use grating scale detection system.Its working principle is that in each machine
It is fitted with grating scale in the placement position of tool hand, is not just permitted when grating scale, which detects, has plastic part on the conveyer belt of the paragraph
Perhaps manipulator continues to launch.
Although above-mentioned technical proposal solves the problems, such as that plastic part mutually collides, but due to the presence of grating scale, each
As soon as conveyer belt paragraph can only exist a plastic part, such as conveyer belt surface left side launch have plastic part then right side can not launch
, transport capacity substantially reduces, and is not able to satisfy production requirement.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides one kind and prevents plastic part from colliding and do not reduce conveyer belt transfer efficiency
Conveyer belt control system.
The technical solution of the present invention is as follows:
Conveyer belt code control system, it includes encoder, PLC controller, manipulator, touch screen and conveyer belt, will be compiled
Code device is mounted on the driving motor main shaft of conveyer belt, real-time monitoring conveyer belt moving distance, monitoring method are as follows: and moving distance=
Encoder pulse number * pulse distance；Encoder connects the data input pin of PLC controller, the PLC control by data line
The control signal output of device processed connects manipulator by data line, sets the start bit of each manipulator in PLC controller
It sets, PLC controller calculates the real time position of plastic part by the real time data of encoder after manipulator dispensing plastic part, in real time
Position calculating method are as follows: plastic part real time position=initial position+moving distance, the PLC controller are connected with touch screen,
Plastic part real-time position information is shown that PLC controller is mechanical at this very moment according to judgement is calculated by PLC controller by touch screen
Whether there are plastic part, judgment method in the corresponding placement position of hand are as follows: known to plastic part real time position and its length and width, it may be determined that its
Shared rectangle frame on a moving belt, the rectangle frame and manipulator are launched frame and are overlapped, then it represents that placement position has plastic part, otherwise for
Nothing has, and waits, and nothing is then launched.
The control method of the conveyer belt code control system are as follows:
S1: parameter setting is carried out by touch screen and set information is transferred to PLC controller, parameter includes mechanical throws
Put initial position, plastic part size, pulse distance；At the same time, conveyor motor starts, driving conveying belt and coding
Device, encoder issue pulse signal transmission to PLC controller；
S2:PLC controller updates each plastic part enforcing location information recorded in memory, at the same time will be updated
Information is transferred to touch screen and real-time display；
S3: manipulator obtains plastic part from injection molding machine；
S4: manipulator pickup is completed and transmits signal to PLC controller；
S5:PLC controller reads each manipulator pickup information；
S6:PLC controller judges whether manipulator current location has plastics according to plastic part position, size information in memory
Part；
S7: when PLC controller judges that some manipulator current location has existed plastic part and then forbids putting part, nothing is then put
Part；
The judging result of s7 is fed back to manipulator by s8:PLC controller；
S9: manipulator puts part and puts the information that part is completed to PLC controller transmission, and at the same time, PLC controller is in memory
It is middle to increase a record, save current zoom plastic part position and size.
The encoder is spiral encoder in one of the embodiments, such as uses rotary encoder, and real-time monitoring is defeated
Band moving distance is sent, monitoring method is pulse distance=conveyer belt transmission shaft perimeter/encoder individual pen umber of pulse.
The invention has the benefit that having abandoned grating scale, allow manipulator plastic part placed side by side, plastic part transported
Journey positions in real time, significantly improves the dispensing ability of conveyer belt, and cost is relatively low.
