Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gypsum board edge sealing, in particular to a gypsum board edge sealing paper alternate continuous supply control method. BACKGROUND

[0002] In the existing use process of gypsum board edge sealing paper rolls, most of them are replaced manually after one roll is used up, among which, for the gypsum board production line that seals first and then cuts to size, the replacement of the edge sealing paper roll that is about to run out can be completed in the gypsum board cutting gap, but it still needs manual observation and control of the replacement time, and most of the time it needs to be stopped for observation. The use of edge sealing paper rolls under manual observation is easy to cause waste of edge sealing paper rolls in order to ensure continuity, and the main problem is how to realize the paper joint between two edge sealing paper rolls. For the supply mode of forming multiple groups of gypsum board edge sealing paper rolls by using one large and one small tray or multiple trays, when replacing the edge sealing paper roll by placing a new roll and a small roll that is about to run out, the time is not grasped well, and the paper roll is easy to be pulled off directly. This mainly reflects the stroke conflict in the paper joint process, thereby reducing the paper joint efficiency. Therefore, there is a lack of an effective continuous supply mode for multiple groups of gypsum boards. SUMMARY

[0029] Figure 1 The present application provides a method for alternately switching a plurality of groups of edge paper rolls based on two elevators to form continuous gypsum board edge paper rolls, and provides a relatively efficient seamless connection and continuous supply method for edge paper rolls, which can reduce the downtime and labor usage in the existing multi-group edge paper roll supply process. DETAILED DESCRIPTION

[0030] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.

[0031] As shown in Figure 1 The present application provides a gypsum board edge sealing paper alternate continuous supply control method, comprising the steps of:

[0032] Step 100, constructing a current working edge sealing paper roll working position and a to-be-switched edge sealing paper roll working position in the same horizontal plane; the edge sealing paper rolls on the current working edge sealing paper roll working position and the to-be-switched edge sealing paper roll working position are always at the same height, which is consistent with the height of the side edge of the gypsum board on the conveying belt, so that the influence of the paper roll vibration during the rotation of the edge sealing paper roll can be reduced;

[0033] Two lifters are constructed, at least two groups of edge sealing paper rolls are arranged on each of the lifters, and the lifters are used to sequentially convey the edge sealing paper rolls arranged thereon to the current working edge sealing paper roll working position or the to-be-switched edge sealing paper roll working position;

[0034] Step 200, detecting the size change of the edge sealing paper roll on the current working edge sealing paper roll working position by using a paper roll size detection device until a set parameter value is obtained;

[0035] Then, the joint of the edge sealing paper roll on the to-be-switched edge sealing paper roll working position is adhered to the surface of the edge sealing paper roll on the current working edge sealing paper roll working position along the conveying direction of the edge sealing paper roll by using a switching mechanical arm;

[0036] At this time, the unused edge sealing paper roll on the lifter in the current working edge sealing paper roll working position is conveyed to the current working edge sealing paper roll working position;

[0037] Subsequently, the current working edge sealing paper roll working position and the to-be-switched edge sealing paper roll working position are switched.

[0038] The two lifters include a first lifter and a second lifter, and the uppermost edge sealing paper roll on the first lifter is arranged in an initial current working edge sealing paper roll working position, and the uppermost edge sealing paper roll on the second lifter is arranged in an initial to-be-switched edge sealing paper roll working position, and when the paper switching operation is performed, wherein:

[0039] The paper head of the edge sealing paper roll on the first lifter in the to-be-switched edge sealing paper roll working position is connected to the inner side wall of the edge sealing paper roll on the current working edge sealing paper roll working position of the second lifter which has been arranged in the conveying path;

[0040] The paper head of the edge banding paper roll on the second lifter in the standby roll change position is connected to the outer surface of the edge banding paper roll currently working on the first lifter.

[0041] The edge banding paper roll on the first lifter in the uppermost position of the action lever is the edge banding paper roll that is first put into work (initially in the current working position of the edge banding paper roll), and then the uppermost edge banding paper roll on the second lifter is the edge banding paper roll that is standby for roll change, and then the uppermost edge banding paper roll on the second lifter becomes the edge banding paper roll currently working after the paper connection action, at which time the edge banding paper roll on the second tray carrier on the first lifter is driven to the same height position as the edge banding paper roll currently working on the second lifter under the drive of the lifting assembly, and the steps are repeated until the roll change action of all the edge banding paper rolls on the two lifters is completed.

[0042] In the state of ignoring the thickness of the edge banding paper roll, the tangential point of the connection of the edge banding paper roll on the first lifter and the second lifter and the edge banding paper roll is located on the Y axis as the center of the circumcenter of the edge banding paper roll.

[0043] The paper head of the edge banding paper roll in the initial current working position of the edge banding paper roll is located in the second quadrant away from the tangential point of the edge banding paper roll.

[0044] The paper head of the edge banding paper roll in the current working position of the edge banding paper roll on the second lifter is located in the first quadrant away from the tangential point of the edge banding paper roll; the roll change robot changes the connection of the edge banding paper roll in the standby roll change position on the first lifter to the inner surface of the edge banding paper roll in the second quadrant of the conveying path on the second lifter.

[0045] The detection position of the roll size detection device for detecting the size of the edge banding paper roll on the second lifter is located in the fourth quadrant of the edge banding paper roll.

[0046] It should be noted that since the roll change and paper connection action destroys the tension of the edge banding paper roll in the process of edge banding of the gypsum board, when the stable tension of the edge banding paper is restored during the conveying process, it is easy to cause the tension to change suddenly and cause the paper to separate at the connection position, or folding phenomenon occurs, which requires a structure to buffer the tension restoration process.

[0047] Therefore, when the edge banding paper roll in the standby roll change position on the first lifter is changed to the edge banding paper roll in the current working position of the edge banding paper roll on the second lifter, the output path of the changed edge banding paper roll on the first lifter is buffered and guided until the paper head of the edge banding paper roll in the current working position of the edge banding paper roll on the first lifter is located in the second quadrant away from the tangential point of the edge banding paper roll.

[0048] In step 200, the paper roll size detection device controls the switching manipulator by triggering an action signal and a paper receiving action signal, and the control method specifically includes:

[0049] The collection position of the triggering action signal is set in the third quadrant of the edge sealing paper roll, and the collection position of the paper receiving action signal is set in the fourth quadrant.

[0050] The triggering action signal controls the switching manipulator to grab the paper head of the edge sealing paper roll in the edge sealing paper roll working position to be switched and close to the front working edge sealing paper roll working position; and the paper receiving action signal is used to control the switching manipulator to adhere the paper head of the edge sealing paper roll in the edge sealing paper roll working position to be switched to the edge sealing paper roll in the current working edge sealing paper roll working position.

[0051] In order to enable the edge sealing paper roll on the lifter to be continuously supplied while the edge sealing paper roll on the gypsum board is continuously supplied, and not to affect the edge sealing action of the gypsum board, at least two groups of edge sealing paper rolls are arranged on each of the lifters, and specifically include:

[0052] The number of edge sealing paper rolls on the first lifter and the second lifter is different by one, and the carrier of the edge sealing paper roll can be mounted on and detached from the first lifter or the second lifter. In this way, after the edge sealing paper rolls on the two lifters are switched several times, the last edge sealing paper roll is located on the lifter with an odd number of edge sealing assemblies (the first lifter or the second lifter), and then the edge sealing paper rolls on the lifter with an even number of edge sealing assemblies have been completely used. By mounting and detaching the carrier of the edge sealing paper roll on the first lifter or the second lifter, the carrier of the edge sealing paper roll with an even number can be replaced at one time, and the lifter with an even number of edge sealing assemblies returns to the initial position. When the edge sealing paper rolls on the lifter with an odd number are completely used, the edge sealing paper rolls are switched to the newly replaced lifter with an even number of edge sealing assemblies, and then the lifter with an odd number of edge sealing assemblies can be replaced, and theoretically, the continuous supply of edge sealing paper rolls can be realized without stopping.

[0053] Each edge sealing paper roll and the carrier can independently rotate relative to each other.

[0054] In the embodiment of the application, two lifters are constructed, and two groups of edge sealing paper rolls are arranged on the two lifters, and the edge sealing paper rolls on the two lifters are continuously switched to realize the continuous supply of four groups of edge sealing paper rolls in terms of quantity. Of course, in actual application, the number of groups can be greater than four, so that the operation of stopping and replacing the edge sealing paper roll during the edge sealing process of the gypsum board is reduced, and the situation that the side edges of the gypsum board are not sealed is avoided as much as possible.

[0055] The above examples are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements are also considered to fall within the protection scope of the present application.
