[0027] The core of the present invention is to provide a molding machine and a control method and a control system thereof, so as to solve the problems of intermittent control and prolonged cycle in the control method of the molding machine.

[0028] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0029] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a control method for a molding machine, the molding machine includes a plurality of moving parts 2 with a common motion area 1, and the control method includes: acquiring current position information of a first moving part 21 and a second moving part 22 in real time; controlling the second moving part 22 to move toward the common motion area 1, and adjusting the motion speed or preset target position of the second moving part 22 in real time according to the current position information, so that the minimum distance between the second moving part 22 and the first moving part 21 is maintained at least at a preset safety distance; wherein the first moving part 21 is a moving part currently in the common motion area 1, and the second moving part 22 is a moving part currently outside the common motion area.

[0030] The molding machine is controlled by the control method. When there are moving parts in the common moving area, the second moving part can be controlled to start moving toward the common moving area without waiting for the first moving part to leave the common moving area, and the current position information of the first moving part and the second moving part is obtained in real time, and the movement speed or the preset target position of the second moving part is adjusted in real time, so that the minimum distance between the second moving part and the first moving part is always maintained at least the preset safety distance, which not only ensures that the first moving part and the second moving part do not collide, but also enables the control of the second moving part to be continuous and uninterrupted, shortening the movement cycle of the second moving part; in addition, the continuous actions of each moving part are flexibly connected and the actions are smooth, thereby realizing fast, efficient and safe control requirements and eliminating a lot of conditional design and alarm information processing.

[0031] It should be noted here that those skilled in the art should be able to understand that the common motion area and several moving parts all have spatial positions passing through the area during the motion process. In addition, the first moving part is currently in the common motion area, which can specifically mean that the whole is currently located in the common motion area, or that part of it is currently located in the common motion area; and the second moving part is currently outside the common motion area means that the second moving part is currently outside the common motion area as a whole.

[0032] In some specific implementation schemes, the current position information can be acquired in real time by an encoder or a detection switch. It is more convenient to monitor and acquire the current position information by real time monitoring by an encoder or a detection switch. Of course, it is understandable that in actual application, other methods commonly used by technicians in this field to acquire the current position information can also be used, such as infrared distance measurement, radar detection, etc. In actual application, it can be selected according to actual needs, and no more specific restrictions are made here. Among them, the results of radar detection can be distributed to other moving parts through a broadcast mode, so that each moving part can accurately grasp the safety boundary (that is, the preset safety distance) in its own movement and action control.

[0033] It should be noted that, generally speaking, the range of the preset safety distance is not less than 3 mm. Of course, it can be understood that the range of values ​​is only an example of the value of the preset safety distance in the embodiment of the present invention. In actual application, other corresponding preset safety distances can also be selected according to actual needs.

[0034] In addition, the present invention also provides a control system for a molding machine, wherein the molding machine includes a plurality of moving parts 2 having a common moving area 1, and the control system includes a collection unit and a control unit.

[0035] An acquisition unit is used to acquire the current position information of the first moving component 21 and the second moving component 22 in real time; a control unit is used to adjust the movement speed of the second moving component 22 in real time according to the current position information, and control the second moving component 22 to move toward the public motion area 1 at the movement speed adjusted in real time by the processing unit; or to adjust the preset target position of the second moving component 22 in real time according to the current position information, and control the second moving component 22 to move toward the public motion area 1 at the preset target position adjusted in real time, so that the minimum distance between the second moving component 22 and the first moving component 21 is maintained at least at a preset safety distance; wherein the first moving component 21 is a moving component currently in the public motion area 1, and the second moving component 22 is a moving component currently outside the public motion area 1.

[0036] The control system of the molding machine inherits the core idea of ​​the control method of the aforementioned molding machine, and the two belong to a general inventive concept. Since the aforementioned control method has the aforementioned technical effects, the control system should also have corresponding technical effects, which will not be elaborated here one by one.

[0037] It should be noted that the acquisition unit may specifically be an encoder or a detection switch, or other acquisition units commonly used by those skilled in the art, such as an infrared rangefinder, a radar detector, etc., which are not further limited herein.

[0038] Similarly, the value range of the preset safety distance is not less than 3 mm. Of course, it can be understood that the value range is only an example of the value of the preset safety distance in the embodiment of the present invention. In actual application, other corresponding preset safety distances can also be selected according to actual needs.

[0039] In addition, the present invention also provides a molding machine, including a frame, on which are arranged a plurality of moving parts 2 with a common motion area 1, and a monitor is also arranged on the frame, and the monitor is used to monitor the current position information of the first moving part 21 and the second moving part 22 in real time; each moving part is configured with a controller, and the controller of the second moving part 22 is used to control the second moving part 22 to move toward the common motion area 1, and adjust the movement speed or preset target position of the second moving part 22 in real time according to the current position information, so that the minimum distance between the second moving part 22 and the first moving part 21 at least maintains a preset safety distance; wherein the first moving part 21 is a moving part currently in the common motion area 1, and the second moving part 22 is a moving part currently outside the common motion area 1.

[0040] In some specific implementation schemes, the aforementioned first moving component 21 can be specifically a tire bead presetting module, the second moving component 22 can be a forming drum chassis module, and the common moving area 1 is simultaneously the bead-up station of the tire bead presetting module and the bead-locking station of the forming drum chassis module. When the tire bead presetting module is loaded with tire bead, it moves to the common moving area and performs bead-up operation in the common moving area; the forming drum chassis module moves to the common moving area after completing the laminating operation of the relevant rubber outside the common area. During this process, when the tire bead is pre-set for bead-up operation, or when the bead-up is completed and ready to leave the common moving area, the forming drum chassis module can move to the common moving area, and the possibility of collision between the two can be avoided by controlling the movement speed. The moving parts on the specific forming machine, which one is the first moving part and which one is the second moving part, need to be scheduled according to the certain sequence set for different moving components in the whole machine process, and they will perform continuous actions according to the scheduling, under the protection of the preset safety distance. Among them, the value range of the preset safety distance is not less than 3mm.

[0041] In order for those skilled in the art to better understand the technical solution of the present invention, the following examples are given in conjunction with the motion relationships of some specific moving parts on the molding machine:

[0042] like Figure 2 As shown, the first moving component is a tire bead presetting module, and the second moving component is a forming drum chassis module. The position marked with the first moving component 21' in the figure is the tire bead loading position, the public moving area 1 is the upper bead position of the tire bead presetting module, and is also the locking bead position of the forming drum chassis module. The position marked with the second moving component 22 in the figure is the rubber bonding position of the forming drum chassis module. After the tire bead is loaded at the position marked with the first moving component 21', the tire bead presetting module will go to the public moving area 1 for upper beading. At the same time, after the bonding at the position marked with the second moving component 22 is completed, the forming drum chassis module will go to the public moving area 1 for locking beading. At this time, according to the whole machine process, the tire bead presetting module and the forming drum chassis module will be scheduled in a certain order, and they will perform continuous actions according to the scheduling under the protection of safety boundary control.

[0043] like Figure 2 As shown in the dotted box, when the tire bead presetting module is in the process of putting on the tire bead in the public movement area 1 or is about to leave the public movement area 1 after the tire bead is put on, and the forming drum chassis module has completed the fitting at the position marked with the second moving part 22, it needs to go to the public movement area 1 to lock the tire bead. At this time, the drum chassis module has received the instruction to go to the public movement area 1, and under the protection of the safety boundary control theory (preset safety distance), the drum chassis module will immediately move to the public movement area 1. Its movement position and movement speed will be automatically calculated by the module itself according to the safety boundary input. The safety boundary will output the position status of other component modules in the surrounding environment of the drum chassis module in real time. The drum chassis module will receive feedback from the safety boundary, control its own status in real time, and make itself approach the public movement area 1. Figure 2 At a certain moment in the process described in the figure, when the tire bead preset module is leaving the common motion area 1, as at the position of the first moving part 21 marked in the figure, the drum chassis module has already moved in advance to the common motion area 1 to the position of the second moving part 22' marked in the figure through the safety boundary control theory. There will be no collision problem in this process under the action of the safety boundary control theory. At the same time, the forming drum chassis module will control its own motion state according to the state of the tire bead preset module under the action of the safety boundary control theory, and its motion position will be as close to the tire bead preset module as possible without colliding with it until it reaches the common motion area 1, thereby achieving fast, efficient and safe control requirements and eliminating a lot of conditional design and alarm information processing.
