Description

Technical Field

[0001] The utility model relates to the technical field of food filling, in particular to a filling machine control system. Background Art

[0002] The stuffing machine is part of the production line of stuffed pastries (such as spring rolls, buns, dumplings, etc.). The use of the stuffing machine can effectively improve the uniformity of stuffing delivery and improve the production efficiency of stuffed pastries. The existing stuffing machines have the following problems:

[0003] The existing filling machine uses relay control, and the electrical circuit is complex. The existing filling machine parameters cannot be set, and the filling amount can only be suitable for the production of a single product. The existing filling amount control is cylinder control. Due to the imbalance of air pressure, there is a large deviation between the single filling amount, and subsequent production cannot be guaranteed.

[0004] Therefore, an intelligent filling machine control system is urgently needed to adjust the filling amount and ensure that the deviation of the single filling amount is small. Summary of the invention

[0005] In order to solve the problem that the filling amount of the existing filling machine cannot be adjusted and the single filling amount has a large deviation, the utility model proposes a filling machine control system which adopts a servo motor as the power source of the filling, and combines a servo driver and a PLC controller to provide a hardware basis for adjusting the filling amount.

[0009] During operation, the dough is provided with a conveyor belt, which includes a drive motor. The speed of the drive motor is controlled by a PLC controller. After the detection unit detects the dough, the PLC controller controls the servo driver to work, and the servo motor drives the filling to be squeezed out from the discharge port. Then the two-position five-way solenoid valve works, and the knife body cuts off the filling, and the filling falls on the dough due to gravity. During this period, the feeding amount is changed by adjusting the power-on time of the servo motor to realize the processing of various stuffed pastries. At the same time, there is no need to worry about the influence of air pressure, and the amount of filling dropped each time is almost the same.

[0010] Furthermore, the control end of the servo drive is electrically connected to the output end of the PLC controller, and a first relay is arranged between the enable end of the servo drive and the output end of the PLC controller, the coil of the first relay is connected to the output end of the PLC controller, and the normally open contact of the first relay is connected to the enable end of the servo drive.

[0011] Furthermore, a second relay is provided between the coil of the two-position five-way solenoid valve and the PLC controller, the coil of the second relay is connected to the output end of the PLC controller, and the normally open contact of the second relay is connected to the coil of the two-position five-way solenoid valve;

[0012] The left chamber and the right chamber of the cylinder are connected to an air source through two-position five-way solenoid valves respectively, and the knife body is fixed to the piston rod of the cylinder.

[0013] Relays are used as signal driving elements, with simple actions and wiring, no need for program control, and easy to use.

[0014] Furthermore, the servo driver is provided with an air switch, and the servo driver is connected to a power supply through the air switch to form a loop.

[0015] Furthermore, the detection unit includes a diffuse reflection photoelectric switch.

[0016] Furthermore, the PLC controller is provided with a manual module, which includes a normally open button, a normally closed button and an emergency stop button. The normally open button, the normally closed button and the emergency stop button are connected in parallel, and one end of the normally open button, the normally closed button and the emergency stop button are connected to a power supply and the other end is connected to an input end of the PLC controller.

[0017] The normally open button is for manual control, which can manually control the power-on time of the servo motor and perform manual unloading. The normally closed button can realize electric unloading, and the emergency stop button can ensure that the machine can stop working immediately when it fails.

[0018] Through the above technical solution, the beneficial effects of the utility model are:

[0019] The utility model provides a hardware foundation for the uniform feeding and adjustable feeding amount of the filling machine. The servo motor is used as the power source, which is more stable than pneumatic feeding and is easy to control. The servo driver is set to control the servo motor, and the PLC controller and HMI module are used to complete the human-computer interaction. The working time of the servo motor can be adjusted to achieve the adjustment of the discharge amount. The filling machine can be used for the production of various filling pastries.

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0025] Example 1

[0026] like Figures 1 to 3 As shown, a filling machine control system comprises a filling feeding drive assembly 1, a material chamber assembly 2 and a material feeding and cutting assembly 3, wherein the material chamber assembly 2 is arranged below the outlet of the filling feeding drive assembly 1, the material chamber assembly 2 is arranged with a discharge port 4, the upper end of the discharge port 4 is arranged with the material feeding and cutting assembly 3, the filling feeding drive assembly 1 comprises a servo motor 6, the control end of the servo motor 6 is connected with a servo driver 7, and the material feeding and cutting assembly 3 comprises a cylinder, a knife body 9 and a two-position five-way solenoid valve 8;

[0030] Preferably, a second relay 14 is provided between the coil of the two-position five-way solenoid valve 8 and the PLC controller 10, the coil of the second relay 14 is connected to the output end of the PLC controller 10, and the normally open contact of the second relay 14 is connected to the coil of the two-position five-way solenoid valve 8;

[0031] The left chamber and the right chamber of the cylinder are connected to the gas source through two-position five-way solenoid valves 8 respectively, and the knife body 9 is fixed to the piston rod of the cylinder.

[0032] Preferably, the servo driver 7 is provided with an air switch 15, and the servo driver 7 is connected to a power supply through the air switch 15 to form a loop.

[0033] Preferably, the detection unit 12 includes a diffuse reflection photoelectric switch.
