Similarly, the first glass group is specifically described as a first target group, and the second glass group is specifically described as a second target group. It is understood that the object may also be a metal or other object that needs to be ground, and this embodiment of the present application is not particularly limited.

The system continuity is an important index for measuring the system performance, for example, in the glass deep processing industry, the system continuity refers to the effective working time of a system judged by the starting state of equipment in the system and the processing state of glass. Thus, the better the system continuity, indicating the higher the production efficiency and lower energy consumption of the equipment in the system.

Based on this, the embodiment of the application provides a control method, a control device, an edging system and a storage medium for an edging system, which can ensure the continuity of the whole edging system and further improve the production efficiency of the edging system.

Referring to fig. 1 and 2, an embodiment of the present application provides a control method of an edging system. The edging system includes first edging machine and second edging machine, and first edging machine and second edging machine are used for carrying out the edging operation to glass, and glass includes first glass. The control method of the edging system comprises the following steps:

s110, acquiring a first specification parameter of a first glass group;

s120, obtaining a first delay time length according to the first specification parameter;

s130, controlling the first glass to be conveyed to the inlet of the first edge grinding machine at intervals of a first delay time, and controlling the first glass passing through the outlet of the first edge grinding machine to be conveyed to the inlet of the second edge grinding machine.

Specifically, the control method is applied to a control device of an edging system, and the control device is a Programmable Logic Controller (PLC) or other Programmable control devices. The multiple sheets of glass are grouped according to specification parameters, and the glass with the same specification parameters is defined as a group of glass groups. The specification parameters refer to size parameters of the glass, such as a length parameter, a width parameter, a thickness parameter and the like, wherein the length parameter represents the length of a long side of the glass, the width parameter represents the length of a short side of the glass, and the thickness parameter represents the thickness of the glass. The terminal device obtains a first specification parameter of the first glass group through ERP (Enterprise Resource Planning), for example: and the terminal equipment is connected with a production data interface of the ERP by scanning the corresponding ID code, so that a plurality of groups of glass groups prestored in a production database are selected. The terminal equipment sends the acquired first specification parameters to the control device in a wireless transmission mode and the like; or the glass is provided with the identity marks such as the two-dimensional code and the ID code, and the control device identifies the identity marks to obtain the specification parameters of the corresponding glass group. It is understood that the number of the glass groups selected by the terminal device is not particularly limited in the embodiments of the present application, for example: at most, the terminal equipment can select thirty groups of glass with different specification parameters. In addition, when terminal equipment has selected multiunit glass group, terminal equipment can also adjust the edging operation order of multiunit glass group to satisfy different production demands.

Wherein, first edging machine 100 is used for carrying out the edging operation to the minor face of glass, and second edging machine 200 is used for carrying out the edging operation to the long limit of glass. Therefore, the edging operation duration of the first edging machine 100 is less than the edging operation duration of the second edging machine 200. In order to ensure the continuity of the edging system, the time interval between two adjacent pieces of first glass entering the inlet of the first edging machine 100 is controlled to be a first delay time, so that the edging speed matching of the first edging machine 100 and the second edging machine 200 is realized. And turning the first glass which finishes the short edge edging operation, for example, rotating by ninety degrees, and conveying the turned first glass to the inlet of the second edging machine 200 so as to carry out the edging operation on the long edge of the first glass, thereby finishing the edging process of the first glass. It can be understood that, according to different edging processes, the number of the edging machines included in the edging system can be adaptively adjusted, and the adjusted edging system also belongs to the protection scope of the embodiment of the present application.

The control method of the edging system provided by the embodiment of the application obtains the first delay time through the first specification parameter of the first glass group, and controls the interval time of the first glass entering the inlet of the first edging machine according to the first delay time so as to realize the edging speed matching of the first edging machine and the second edging machine, thereby ensuring the continuity of the edging system, further improving the production efficiency of the edging system, realizing the automatic control of the edging system and reducing the cost of the edging system to a certain extent.

Referring to fig. 3, in some embodiments, the first specification parameters include a length parameter and a width parameter. Step S120 includes the substeps of:

s310, obtaining a first measurement parameter of the first glass;

s320, determining that the first measurement parameter is within a first preset range, determining that the first glass is not damaged, and obtaining a first delay time length according to the width parameter and the length parameter.

Specifically, the first edge grinding machine is connected with the control device through a bus and other connection modes. The first edger collects actual specification parameters of the first glass fed into the inlet of the first edger, such as: the inlet of the first edge grinding machine is provided with a first sensor, and the first sensor collects the actual width parameter of the first glass. The control device judges whether the actual wide parameter is within a first preset range or not so as to ensure that the collected glass is matched with the first glass group. The first preset range is composed of a maximum error value and a minimum error value allowable by the wide parameter in the first specification parameter. When the actual wide parameter is within a first preset range and the first glass is not broken, calculating to obtain a first delay time length T1 which is W1/L1 according to the wide parameter W1 and the long parameter L1 sent by the terminal equipment. The time interval for feeding the first glass into the inlet of the first edge grinding machine is set according to a first delay time period T1, for example: if the first delay time period T1 is calculated to be five seconds, a sheet of the first glass in the first glass group is fed into the first edger inlet every five seconds. And when the actual wide parameter is not in the preset range, the current detected glass does not belong to the first glass group, or the first sensor has wrong acquisition and the like. At this time, the control device generates an alarm signal in the form of sound, light, or the like, and suspends transmission to the glass. It is understood that the judgment of the glass breakage condition can be realized by corresponding sensors or relay interaction, and the embodiment of the application is not particularly limited. The damage includes the occurrence of cracks in the glass, local area bulging of the glass, and the like. When the first glass is damaged, the sequence of the first glass in the first glass group can be adjusted according to an adjusting instruction sent by the terminal equipment or a preset adjusting strategy so as to ensure the continuity of the edge grinding system.

Referring to fig. 4, in some embodiments, the step of "controlling the passage of the first glass through the first edger outlet to the second edger inlet" in step S130 includes the sub-steps of:

s410, controlling the first glass passing through the outlet of the first edge grinding machine to turn;

and S420, conveying the turned first glass to an inlet of a second edge grinding machine.

Specifically, first edging machine includes both ends, and the export of first edging machine is used for conveying the first glass after first edging machine edging operation, and the entry of first edging machine is used for conveying the first glass that does not edging operation of first edging machine, and the same can define the entry and the export of second edging machine. The control device controls the turning of the first glass through the first edging machine outlet, for example: the controller controls the first glass completing the short edge edging operation to rotate ninety degrees so that the long edge of the first glass is directed toward the entrance of the second edging machine.

Referring to fig. 5, in some embodiments, after step S420, the method of controlling an edging system further includes the steps of:

s510, obtaining a second measurement parameter of the first glass;

s520, determining that the second measurement parameter is within a second preset range, and controlling the first glass conveyed to the inlet of the second edge grinding machine to be arranged according to a preset distance.

Specifically, the second edge grinding machine is connected with the control device through a bus and other connection modes. The second edging machine gathers the actual specification parameters of the first glass that is fed into the second edging machine inlet, for example: the second edging machine entry is equipped with the second sensor, and the second sensor is gathered first glass's actual long parameter. The control device judges whether the actual length parameter is within a second preset range or not so as to ensure that the collected glass is matched with the first glass group. The second preset range is composed of the maximum error value and the minimum error value allowable by the long parameter in the first specification parameter. And when the actual length parameter is within a second preset range, controlling the distance between the adjacent first glass fed into the inlet of the second edge grinding machine to be a preset distance so as to prevent the glass collision phenomenon.

In addition, a counter can be arranged at the outlet of the second edge grinding machine and used for counting the first glass sent out of the outlet of the second edge grinding machine, and when the counted value is not equal to the number of the first glasses included in the first glass group, the second edge grinding machine is controlled to carry out edge grinding operation on the first glass in the first glass group in a circulating mode.

Hereinafter, the following description will be made in detail by taking the terminal device as an example of selecting two glass groups (a first glass group and a second glass group) in combination with the features described in the above embodiments. Wherein the first glass group and the second glass group have different specification parameters.

Referring to fig. 6, in some embodiments, the method of controlling an edging system further comprises the steps of:

s610, determining that all the first glass group passes through an outlet of the first edge grinding machine, and acquiring a second specification parameter of the second glass group;

s620, obtaining a second delay time according to the second specification parameter, and controlling the second glass to be conveyed to the inlet of the first edge grinding machine at intervals of the second delay time;

s630, obtaining the edging state of the second edging machine to the first glass group, and controlling the second glass passing through the outlet of the first edging machine to turn to the inlet of the second edging machine according to the edging state.

Specifically, a counter is arranged at the outlet of the first edge grinding machine and used for counting the first glass sent out of the outlet of the first plate grinding machine. When the counted value is equal to the number of the first glass included in the first glass group, that is, when all the first glass included in the first glass group passes through the edge grinding operation of the first edge grinding machine, the control device obtains the second specification parameter of the second glass group through the terminal device, and controls the first edge grinding machine to carry out the edge grinding operation on the second glass according to the method corresponding to the above embodiment. For example, the second specification parameters include a width parameter W2 and a length parameter L2 of the second glass, when the actual width parameter of the second glass is judged to be within a preset range and the second glass is not broken, a second delay time period T2 which is W2/L2 is calculated according to the width parameter W2 and the length parameter L2 of the second glass, and an interval time period for feeding the second glass into the inlet of the first edge grinding machine is set according to the second delay time period T2. Because the specification parameters of the first glass group and the second glass group are different, when the second glass is controlled to turn and is transmitted to the second edge grinding machine, the edge grinding state of the second edge grinding machine needs to be judged, namely whether the second edge grinding machine finishes the edge grinding operation of all the first glass is judged. When the edging state indicates that the edging is not complete, the rotation of the second glass or the conveyance of the second glass is suspended. When the edging state indicates that the edging system is finished, the second edging machine is controlled to adjust the opening and closing angle according to the second specification parameters, and the second glass rotated by ninety degrees is conveyed to the inlet of the second edging machine, so that continuous edging operation of the glass with different specifications is realized, and the production efficiency of the edging system is improved.

Referring to fig. 7, the embodiment of the present application further provides a control device of an edging system. The edging system includes first edging machine and second edging machine, and first edging machine and second edging machine are used for carrying out the edging operation to glass, and glass includes first glass. The control device includes:

a first module 300 for obtaining a first specification parameter for a first group of glasses;

a second module 400, configured to obtain a first delay time according to the first specification parameter;

and a third module 500 for controlling the first glass to be conveyed to the inlet of the first edge grinding machine at intervals of the first delay time length and controlling the first glass, which is discharged through the first edge grinding machine, to be conveyed to the inlet of the second edge grinding machine.

It can be seen that the contents in the embodiments of the control method of the edge grinding system are all applicable to the embodiments of the control device, the functions implemented by the embodiments of the control device are the same as those in the embodiments of the control method of the edge grinding system, and the beneficial effects achieved by the embodiments of the control method of the edge grinding system are also the same as those achieved by the embodiments of the control method of the edge grinding system.

Referring to fig. 8, the embodiment of the present application further provides an edging system. The edging system comprises a control device of the edging system as described in the previous embodiments, a first edging 100, a second edging machine 200 and a steering device 600. Wherein, turn to device 600 and set up between first edging machine 100 and second edging machine 200, turn to device 600 and be used for turning to the operation to first glass and/or second glass.

For example, the steering device 600 is provided with a third sensor, and the steering device 600 is connected to the control device by a connection means such as a bus. The rising edge of the third sensor is set to be effective, and when the first glass or the second glass is sent out from the outlet of the first edge grinding machine 100 and the third sensor detects the first glass or the second glass, the level state of the third sensor is changed from low level to high level. At this time, the steering device 600 controls the first glass or the second glass to rotate ninety degrees so that the long side of the second glass is directed toward the entrance of the second edge grinding machine 200, thereby ensuring the continuity of the edge grinding system.

It can be seen that, the contents in the embodiments of the control method of the edge grinding system are all applicable to the embodiments of the edge grinding system, the functions specifically implemented by the embodiments of the edge grinding system are the same as those in the embodiments of the control method of the edge grinding system, and the beneficial effects achieved by the embodiments of the control method of the edge grinding system are also the same as those achieved by the embodiments of the control method of the edge grinding system.
