Description

Technical Field

[0001] The present invention relates to the technical field of gypsum board production, and particularly relates to an edge-sealing paper joint traction paper connecting device. Background Art

[0002] In the supply of existing gypsum board edge-sealing paper rolls, most are single-roll supply at a single station, which makes it necessary to stop the machine for roll change when changing the edge-sealing paper roll. In view of this problem, a continuous supply solution for multiple workstations with multiple edge-sealing paper rolls is provided in the prior art. In this process, how to connect the edge-sealing paper roll that is about to be used up and the edge-sealing paper roll to be used is the main problem in realizing the continuous supply of edge-sealing paper rolls.

[0003] Although in the prior art, a multi-degree-of-freedom robotic arm with a clamping component can be used to clamp and traction the paper head of the edge-sealing paper roll to be used to the edge-sealing paper roll that is about to be used up, there are problems including that it is impossible to maintain the paper connecting state between the edge-sealing paper roll that is about to be used up and the edge-sealing paper roll to be used, which makes the paper connection prone to disconnection after connection. And when connecting the edge-sealing paper rolls at multiple workstations, there are differences in outer surface and inner surface paper connection in the paper head connection of the edge-sealing paper roll to be connected to the edge-sealing paper roll that is about to be used up, and the existing robotic arm requires more degrees of freedom and stroke control to complete the paper connecting action.

[0053] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0054] As Figure 5 、 Figure 6 and Figure 7 shown, based on the paper receiving of the multi - station edge - sealing paper roll proposed by the present invention, taking two stations and the edge - sealing paper rolls on the stations being alternately supplied as an example, that is to say, the traction device in the present invention realizes;

[0055] As Figure 1 shown, the present invention provides an edge - sealing paper joint traction and paper receiving device, including a rotating arm 1. One end of the rotating arm 1 is provided with a circumferential clamping component 3 through a corner component 2, and the other end of the rotating arm 1 is provided with a rotating shaft 4.

[0056] The circumferential clamping component 3 includes a first circumferential drive part 5 and a guide part 6.

[0057] A clamping and guiding cavity 7 with an open upper end is formed between the guide part 6 and the first circumferential drive part 5. The two ends of the guide part 6 and the first circumferential drive part 5 respectively form a paper head inlet end 8 and a paper head outlet end 9 of the clamping and guiding cavity 7. And the guide part 6 at the paper head outlet end 9 is in contact with the first circumferential drive part 5, and the guide part 6 at the paper head inlet end 8 is far from the first circumferential drive part 5.

[0058] The rotating arm 1 rotates by a set angle around the rotating shaft 4 under the drive of an external force, so that the joint of the edge banding paper roll enters the clamping and guiding cavity 7 through the paper head inlet 8, and the first circumferential driving part 5 outputs and clamps the joint of the edge banding paper roll from the paper head outlet 9 through frictional transmission with the joint of the edge banding paper roll entering the clamping and guiding cavity 7.

[0059] The corner assembly 2 is used to drive the circumferential clamping assembly 3 to rotate circumferentially, so that the edge banding paper roll disengages from the open upper end of the clamping and guiding cavity 7.

[0060] When the present invention is working, it is default that the rotating arm 1 and the circumferential clamping assembly 3 are integrally located between two edge banding paper roll stations. When performing the paper connecting operation, the rotating arm 1 rotates around the rotating shaft 4 under the drive of an external force, so that the circumferential clamping assembly 3 approaches the edge banding paper roll station to be connected with paper, and the paper connecting head D of the edge banding paper roll on the edge banding paper roll station to be connected with paper enters the paper head inlet 8. Since the paper head inlet 8 is an opening with a certain width, in the present invention, there is no need for a precise positioning and clamping process for the paper head, and only the paper connecting head of the edge banding paper roll needs to be aligned with the opening range of the paper head inlet 8.

[0061] As Figure 5 、 Figure 6 and Figure 7 shown, the initial position of the rotating arm 1 is located between two edge banding paper rolls (the edge banding paper roll F that is about to be used up and the edge banding paper roll E to be used).

[0062] The rotating arm 1 rotates, and the end of the paper connecting head D intersects with the rotation path of the paper head inlet 8 at the contact point C between the paper head inlet and the paper connecting head (tangent in an ideal state).

[0063] When the paper connecting head D of the edge banding paper roll completely enters the clamping and guiding cavity 7, the first circumferential driving part 5 starts to rotate circumferentially. Through the frictional transmission between the first circumferential driving part 5 and the guiding part 6, the paper connecting head of the edge banding paper roll is output from the paper head outlet 9. At this time, when the paper connecting head of the edge banding paper roll is output from the paper roll outlet 9, the frictional force between the guiding part 6 and the first circumferential driving part 5 on the edge banding paper roll reaches the maximum, so as to clamp the joint of the edge banding paper roll.

[0064] As Figure 7 shown, the rotating arm 1 rotates in the reverse direction, pulls out the paper connecting head D from the edge banding paper roll E to be used, and forms a conveying path for the pulled-out edge banding paper G. The paper connecting head D contacts the paper connecting point B of the edge banding paper roll that is about to be used up. Obviously, at this time, the cylindrical roller 51 is tangent to the edge banding paper roll F that is about to be used up at B.

[0065] In the case of alternately supplying edge-sealing paper rolls for two operations, the relative position of the path for transporting the edge-sealing paper roll to the side of the gypsum board with respect to the operations of the edge-sealing paper rolls at two (or multiple edge-sealing paper roll stations), then the traction paper-connecting device needs to consider the travel difference between the two and the paper-connecting orientation. Specifically:

[0066] For two edge-sealing paper roll stations, where one edge-sealing paper roll station is close to the edge-sealing paper roll transport path. After the edge-sealing paper roll at the edge-sealing paper roll station close to the edge-sealing paper roll transport path is almost used up, the traction paper-connecting device pulls the joint of the edge-sealing paper roll at the other edge-sealing paper roll station far from the edge-sealing paper roll transport path. Since the paper-connecting position is located at or near the circumference of the edge-sealing paper roll, it is convenient for the traction paper-connecting device to radially press and contact the traction paper head on the edge-sealing paper roll, thus achieving stable paper connection. Due to the change in travel at the starting end of the edge-sealing paper roll and the transport path, the surface transport tension of the edge-sealing paper roll also changes. At this time, if the traction paper-connecting device directly disengages, it is easy for the paper-connecting position to separate due to the sudden change in the surface tension of the transported edge-sealing paper roll.

[0067] Therefore, in the present invention, after the rotating arm 1 completes the paper-connecting action, the rotating arm 1 loses the rotating torque. At this time, the transport path of the edge-sealing paper roll passes between the first circumferential driving part 5 and the guiding part 6. That is to say, the circumferential clamping assembly 3 also exists on the transport path of the edge-sealing paper roll at this time. Then, the tension of the edge-sealing paper roll will exert a force perpendicular to the edge-sealing paper roll on the first circumferential driving part 5 to restore to the state of consistent tension. Therefore, the gravity of the rotating arm 1 and the structures arranged thereon as a whole will block the instantaneous restoration of the tension on the edge-sealing paper roll (occurring in the case of disengaging immediately after paper connection). That is, the rotating arm 1 and the structures arranged thereon as a whole will rotate around the rotating shaft 4 under this acting force, thereby performing the tension buffering action.

[0068] If the next paper connection is required, then the edge-sealing paper roll needs to be disengaged from between the first circumferential driving part 5 and the guiding part 6. In the present invention, the edge-sealing paper roll is disengaged from the open upper end of the clamping and guiding cavity 7 by rotating the circumferential clamping assembly 3.

[0069] Among them, the cross-section of the clamping and guiding cavity 7 is an arc with a gradually decreasing width.

[0070] For this reason, as Figure 2 shown, the present invention provides a specific embodiment of the corner assembly 2, including a rotating frame 21 rotatably installed at the end of the rotating arm 1 and a second driving part 22 for driving the rotating frame 21 to perform circumferential rotation.

[0071] The first circumferential driving part 5 is installed on the rotating frame 21 through the connecting bracket 23, and the guiding part 6 is arranged on the connecting bracket 23 between the first circumferential driving part 5 and the rotating frame 21.

[0072] In the paper receiving operation for two edge-sealing paper roll stations, although the paper receiving head of the edge-sealing paper roll is at a fixed position, the positions are different. When switching the edge-sealing paper roll station for paper receiving, the traction action end also needs to change (that is, the conversion between the paper head inlet end 8 and the paper head outlet end 9). For this reason, in the present invention, the guiding part 6 is installed on the rotating frame 21 through a guiding chute 24 arranged on the rotating frame 21. The guiding chute 24 enables the guiding part 6 to slide along the circumference of the first circumferential driving part 5 and causes the conversion between the paper head inlet end 8 and the paper head outlet end 9.

[0073] In order for the first circumferential driving part 5 and the guiding part 6 to complete precise guiding and clamping, the guiding part 6 includes an arc section 61, and both ends of the arc section 61 are connected with a circumferential section 62. Among them, the arc section 61 and the circumferential section 62 are in smooth transition.

[0074] Furthermore, in order to more clearly illustrate the working principle of the first circumferential driving part 5, the present invention provides a specific implementation manner of the first circumferential driving part 5, including a cylindrical roller 51 installed on the connecting bracket 23 and a servo motor 52 for driving the circumferential rotation of the cylindrical roller 51. Among them, when the circumferential section 62 serves as the paper head outlet end 9, it has the same center as the cylindrical roller 51. In this way, by controlling the diameter of the circumferential section 62, the cylindrical roller 51 can be determined, and the circle formed by the cross-section of the cylindrical roller 51 always serves as the inscribed circle of the circle formed by the arc section 61.

[0075] A paper head inlet end 8 and a paper head outlet end 9 are formed between the circumferential section 62 and the cylindrical roller 51.

[0076] A transmission component 10 is arranged inside the rotating arm 1, and a clutch component 11 is arranged on the side wall of the rotating arm 1.

[0077] The transmission component 10 is used to transmit the torque of the rotating shaft 4 to the guiding part 6 to move the guiding part 6 along the guiding chute 24.

[0078] The clutch component 11 is used to control whether the transmission component 10 is in transmission connection with the rotating shaft 4.

[0079] Furthermore, as Figure 2As shown, in the present invention, to more clearly illustrate the above working principle, a specific embodiment of the transmission assembly 10 is provided. The purpose of the transmission assembly 10 is to couple the state of the guide member 6 moving in the guide chute 24 and the rotational state of the rotating shaft 4 (that is, when performing paper roll splicing of the edge banding paper rolls at multiple stations, the paper roll inlet end 8 needs to be adjusted according to the different stations of the edge banding paper rolls or the two above are exchanged). The transmission assembly 10 includes a first transmission rod 101 installed inside the rotating arm 1 along the length direction of the rotating arm 1 and a second transmission rod 102 key - connected to the first transmission rod 101. The second transmission rod 102 can move axially along the first transmission rod 101.

[0080] It should be noted that in the above, the rotation between the rotating arm 1 and the rotating shaft 4 is relative, that is, the rotating shaft 4 is relatively stationary when the rotating arm 1 rotates.

[0081] One end of the second transmission rod 102 meshes with the rotating shaft 4, and the end of the first transmission rod 101 away from the second transmission rod 102 is connected to a rack 105 provided on the guide member 6.

[0082] A connecting spring 103 is sleeved on the rod body of the second transmission rod 102. A bevel gear 104 is sleeved on the rod body of the second transmission rod 102 at one end of the connecting spring 103, and one end of the connecting spring 103 is rotatably connected to the bevel gear 104. The other end of the connecting spring 103 is fixedly connected to the rotating arm 1.

[0083] Among them, as Figure 2 and Figure 4 shown, the clutch assembly 11 is connected to the bevel gear 104. The connecting spring 103 makes one end of the second transmission rod 102 mesh with the rotating shaft 4 in the initial state. The clutch assembly 11 is used to apply an axial force along the transmission rod to the bevel gear 104 to disengage the second transmission rod 102 from the rotating shaft 4. The clutch assembly 11 includes a third driving part 111 and a bevel gear 112 meshing with the bevel gear 104. The third driving part 111 drives the bevel gear 112 to move radially along the bevel gear 104 and does not disengage from the bevel gear 104.

[0084] Furthermore, it should be noted that the third driving part 111 in the present invention specifically includes a servo - motor and an eccentric wheel rotated by the servo - motor. The axial displacement of the bevel gear 104 is driven by the stroke difference of the rotation of the eccentric wheel.

[0085] The present invention provides a specific embodiment of a rotating frame 21. The rotating frame 21 includes a square base 25. On one surface of the square base 25, a rotating disk base 26 is provided. The rotating disk base 26 is embedded in the end of the rotating arm 1. An annular rack 27 is provided on the outer circle of the rotating disk base 26. The output end of the second driving part 22 meshes with the annular rack 27. On the other surface of the square base 25, a guiding chute 24 is provided. Wherein, the rotating disk base 26 is specifically an annular structure arranged on the surface of the square base 25 and protruding from the surface of the square base 25. The annular structure is embedded in the end of the rotating arm 1, aiming to increase the rotational contact with the rotating arm 1. The two can be installed and connected through a bearing or a damping ring gasket to maintain stability during connection and rotation.

[0086] As Figure 3 shown, then to achieve the controllable adjustment of the guiding member 6 along the guiding chute 24 and the stable rotation of the entire rotating frame 21, the end of the first transmission rod 101 far from the second transmission rod 102 penetrates through the center of the rotating disk base 26 along the center of the rotating disk base 26 and meshes with the rack 105 provided on the guiding member 6. That is to say, the center of mass of the rotating disk base 26 and the circumferential clamping assembly 3 installed thereon as a whole is located on the axis where the center of the rotating disk base 26 is located.

[0087] Moreover, the rotation of the circumferential clamping assembly 3 driven by the corner assembly 2 in the present invention is a reciprocating action. That is, when the edge-sealing paper roll disengages from the open upper end of the clamping and guiding cavity 7 and returns to the initial position, the always meshing connection state of the first transmission rod 101 and the rack 105 is not affected. Then even when the corner assembly 2 drives the circumferential clamping assembly 3 to rotate to a certain set angle, the transmission assembly 10 can still transmit the driving torque of the rotating shaft 4 to the guiding member 6 under the control of the clutch assembly 11, that is, it can meet the active adjustment in the case of different clamping positions of the edge-sealing paper roll joints at a certain height or a certain angle, thereby improving the applicability of the present invention in multiple working conditions during actual work.

[0088] Furthermore, regarding the movement of the guiding member 6 in the guiding chute 24 in the present invention, its purpose is to achieve the switching between the paper head inlet end 8 and the paper head outlet end 9. The rotation of the rotating shaft 4 and the movement of the guiding member 6 are coupled by the clutch assembly 11, thereby avoiding the design of a driving part for the movement of the guiding member 6 along the guiding chute 24 and avoiding structural redundancy.

[0089] On the other hand, in the specific embodiment of the operation of the present invention, a driving part for the guiding member 6 to move along the guiding chute 24 can also be designed independently, for example, directly using a pneumatic cylinder or a hydraulic cylinder as the driving part.

[0090] Further, in the present invention, the movement of the guiding member 6 in the guiding chute 24 can also be coupled with the driving state of the servo motor 52 through the clutch assembly 11.

[0091] It should be further noted that, of course, in the present invention, the switching between the paper head inlet end 8 and the paper head outlet end 9 is realized, so that the edge-sealing paper joint traction and paper receiving device provided by the present invention mainly acts on the alternating operation of the edge-sealing paper rolls at two edge-sealing paper roll stations. The traction and paper receiving device of the present invention is arranged between two edge-sealing paper roll stations, and the paper receiving heads of the edge-sealing paper rolls at the two edge-sealing paper roll stations are arranged at a fixed position.

[0092] In the paper receiving actions of edge-sealing paper rolls at more stations and more complex stations, as long as the end of the paper receiving head is tangent to the rotation path of the paper head inlet end 8, the paper receiving head D can enter the paper head inlet end 8. During the continuous rotation of the rotating arm 1, through the path constraint of the clamping and guiding cavity 7, the paper receiving head D is moved along the set path.

[0093] Of course, on the basis of the present invention, the rotating arm 1 can be designed to be telescopic to make up for the defect that the path planning of the rotating arm 1 is relatively complex due to the size difference between the edge-sealing paper roll that is about to be used up and the edge-sealing paper roll to be used (since the position of the rotating shaft of the edge-sealing paper roll does not change).

[0094] Further, it should be noted that the traction and paper receiving device provided in the present invention is only used for the paper receiving actions of edge-sealing paper rolls at multiple stations and provides a relatively ideal paper receiving position. As for how to set the sticking medium on the paper receiving head, it is not the focus of the design of the present invention. However, to ensure the rigor of the present invention:

[0095] The medium for paper receiving and sticking of the paper receiving head in the present invention can specifically be double-sided tape. Then, the timing of the combination of the double-sided tape and the paper receiving head can be that after the rotating arm 1 clamps the paper receiving head D and the paper receiving head D is in the state of being output from the paper head outlet end, other mechanical structures are used to stick the double-sided tape on the paper receiving head.

[0096] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
