Embodiment 1

[0020] This embodiment provides a method for controlling material delivery, figure 1 is the flowchart of the method, such as figure 1 As shown, the method includes the following processing:

[0021] Step 101: Obtain the target weight of the material to be delivered;

[0022] In this embodiment, the material to be delivered may be color masterbatch, or other materials, which are not specifically limited in this embodiment. Wherein, the target weight of the material to be delivered can be manually input by the operator, or can be allocated by the control device.

[0023] Step 102: Control the motor to release materials according to the target weight and control the weighing device to weigh the delivered materials;

[0024] In step 102, controlling the motor to release the materials is to control the movement of the motor so as to control the rotation of the screw driven by the motor to bring out the materials to be delivered, and complete the delivery of the materials to be d...

Embodiment 2

[0033] In this embodiment, taking the material to be delivered as masterbatch as an example, the method for controlling delivery of materials provided by the present invention is described.

[0034] In this embodiment, through the control logic and method, the working process of feeding the original color masterbatch machine is changed, and the weighing of the color masterbatch machine and the feeding process of the motor are decomposed, so as to avoid the vibration of the load cell caused by the vibration of the motor to the greatest extent. resulting error.

[0035] In this embodiment, the controller interface uses an analog input port (4-20mA or 0-10V) to receive the signal of the pressure sensor for weighing, and an analog output port (4-20mA or 0-10V) for To control the operation of the feeding motor, an RS485 communication interface is connected to the handheld operator, and the handheld operator sets the target weight for weighing and the start and stop of the operation...

Embodiment 3

[0045] This embodiment provides a device for controlling material delivery, which is used to implement the method for controlling material delivery provided by the present invention. image 3 is the block diagram of the device, as image 3 As shown, the device includes the following components:

[0046] An acquisition module 31, configured to acquire the target weight of the material to be delivered;

[0047] The first control module 32 is used to control the motor to drop the material according to the target weight and control the weighing device to weigh the dropped material;

[0048] Optionally, the material to be delivered is color masterbatch, the second weight is no more than 0.1 gram, and the first weight is no more than 1 gram.

[0049] The second control module 33 is used to control the motor to drop the material of the second weight each time when the weight of the remaining materials to be dropped is not greater than the first weight, and to control the motor to s...

Abstract

The invention discloses a method and device for controlling throwing of a material and aims at solving the problem that an error is produced in a material weighing process as a motor vibrates in a material throwing process in related technology. The material throwing controlling method disclosed by the invention comprises the following steps: acquiring target weight of material to be thrown; controlling the motor to throw the material according to the target weight and controlling a weighing device to weigh the thrown material; when the weight of the residual to-be-thrown material is not morethan first weight, controlling the motor to throw a material with second weight every time, and controlling the motor to stop running after the material with the second weight is thrown every time; and when the motor stops running, controlling the weighing device to weigh the weight of the thrown material until the weight of the thrown material reaches the target weight, and controlling the motorto stop throwing of the material. The method disclosed by the invention improves material throwing accuracy.

Description

technical field [0001] The invention relates to the technical field of material delivery, in particular to a method and device for controlling material delivery. Background technique [0002] In manufacturing, when dyeing molds, it is necessary to accurately weigh solid color masterbatches of various colors, and then mix the solid color masterbatches in a certain proportion and melt them into liquid dyes for use. Since the expected color is obtained by mixing the dyes, the weighing accuracy of the color masterbatch is required to be at least 0.1 gram level. With the development of industrial automation, general modern factories use color masterbatch machines to automatically weigh the weight of various color masterbatches, and then put the weighed color masterbatches into the mixing container for mixing. The whole process does not require human intervention. The weight of the color masterbatch machine is mostly to use the motor movement to control the screw rotation to brin...
