Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
example 1
Referring to fig. 1, the device for external control of the toothpaste filling machine rejecting mechanism comprises a single chip microcomputer, a high-speed optical coupler, a normally closed normally open circuit and an output driving circuit, wherein the single chip microcomputer is electrically connected with the high-speed optical coupler and the output driving circuit respectively, and the output driving circuit is electrically connected with the normally closed normally open circuit.
The high-speed optical coupler can collect external signals and send the external signals to the single chip microcomputer for processing. The high-speed optocoupler isolates external equipment from the device, and prevents mutual interference of internal and external signals of the device.
The single chip microcomputer receives external signals, and controls the output driving circuit to send signals to the filling machine and the removing mechanism thereof through logic operation.
The output driving circuit amplifies the external signal output by the single chip microcomputer, enhances the driving capability of the output signal and can realize the effect of external isolation.
The normally closed and normally open circuit can convert a magnetic switch signal of the magnetic switch and a control signal of the ejector rod, so that a correct feedback signal is ensured to be provided for the filling machine, and the filling machine is ensured not to be alarmed and shut down.
As shown in fig. 1, the high-speed optical coupler respectively receives a main shaft zero position sensor signal, a channel identification sensor signal, an ejector rod control signal and a rejection signal of the detector, wherein the channel identification sensor signal is set for a double-channel filling machine and used for judging which channel the product is in, and the channel identification sensor signal is not needed for a single-channel filling machine.
The detector is an instrument for detecting whether the product is defective, and once the detector detects that the product is defective, the detector sends a rejection signal to the single chip microcomputer.
The normally closed and normally open circuit receives the ejector rod control signal and the magnetic switch signal of the magnetic switch.
The output driving circuit sends a conversion signal to the normally closed and normally open circuit and can send a rejection signal to the rejection mechanism.
Example 2
With reference to fig. 1 and 2, a method for controlling the external of a toothpaste filling machine rejecting mechanism, which is described in embodiment 1, includes the following steps:
step 1: initializing the device, acquiring a spindle zero position sensor signal, an ejector rod control signal and a rejection signal of a detector by a high-speed optocoupler, and sending the signals to a single chip microcomputer for processing;
if the filling machine is a double-channel filling machine, the high-speed optocoupler collects signals of the channel identification sensor and is used for judging which channel the product is in.
Certainly, for the double-channel filling machine, an ejector rod and a magnetic switch of one channel are additionally arranged, and the corresponding signal acquisition is only needed.
Step 2: the single chip microcomputer judges whether a main shaft of the filling machine moves to an original point or not according to a main shaft zero position sensor signal, judges whether a push rod control signal is in a high level or not once the main shaft is detected to move to the original point, and does not need to be removed at the moment if the push rod control signal is in the high level; if the level is low, the filling machine needs to be rejected at the moment, and the singlechip does not send any output signal at the moment, so that all the parts are controlled by the filling machine;
and step 3: if the ejector rod control signal is in a high level, whether the detector detects a defective product or not is continuously judged, if the detector detects the defective product, the detector sends out a rejection signal, after the singlechip receives the rejection signal, the singlechip controls the normally closed and normally open circuit to convert the ejector rod control signal and a magnetic switch signal of the magnetic switch into a low level, and the output drive circuit is controlled to send a rejection instruction to the rejection mechanism after delaying for a plurality of periods according to actual conditions.
If the detector does not detect a defective product, the device does not perform any operation.
When the ejector rod control signal is at a low level, the ejector rod does not act, and the manipulator cannot take the product away, so that the product flows to the removing mechanism.
When the magnetic switch signal of the magnetic switch is at a low level, the normally closed and normally open circuit outputs a feedback signal to the filling machine, so that the filling machine is ensured not to be alarmed and shut down.
Table 1 filling machine original system logic operation truth table
| Name (R) | Ejector control signal | Magnetic switch feedback signal | Rejection signal |
| Without rejection of original machine | 1 | 0 | 0 |
| Removing original machine | 0 | 1 | 1 |
It can be seen from table 1 that when the existing filling machine rejects, a low level signal needs to be sent to the ejector rod to control the ejector rod not to jack up, so that the manipulator cannot take away the defective product, and therefore the signal fed back by the magnetic switch of the filling machine is at a high level when the defective product flows to the reject port. If the control signal of the ejector rod is low level and the feedback signal of the magnetic switch sensor is low level, the filling machine can judge that the machine has faults and stop the machine immediately to alarm.
TABLE 2 truth table of logic operation of the present invention
As can be seen from table 2, as long as the detector does not detect a defective product, the apparatus does not output any control signal, and all the controls are automatically completed by the filling machine; if the detector detects a defective product and the original machine does not reject signals, the device immediately pulls down the magnetic switch sensor and the ejector rod control signals and outputs rejection signals to the outside.
The invention solves the problem that the removal device needs to be repeatedly installed when the toothpaste filling machine is additionally provided with the detection equipment, thereby not only simplifying the installation and control of the detection equipment, but also reducing the equipment cost of enterprises. Meanwhile, the device can be used for a toothpaste filling production line and can also be used for filling production lines in other industries, and the device is strong in universality and wide in application space.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art may make modifications, alterations, additions or substitutions within the spirit and scope of the present invention.
