Abstract

The present invention discloses a paper roll storage and feeding device for an automatic paper splicing machine, which includes a discharging slope and a retaining belt. The discharging slope slopes downward and towards the discharging direction; both ends of the retaining belt are respectively located above and below the discharging slope, and the retaining belt can generate a damping force that hinders the paper roll from rolling downward along the discharging slope. Among them: both ends of the retaining belt are fixedly connected to the frame, and the retaining belt can elastically stretch; or, one end of the retaining belt is fixedly connected to the frame, the other end of the retaining belt is slidably installed on the frame and frictionally connected to the frame, or, the other end of the retaining belt is wound around a tape winding cylinder that can rotate and is frictionally connected to the frame. By forming a retaining belt on the discharging slope that can be slowly stretched, moved or elongated, the discharging speed of the paper roll storage is slowed down, so that the paper roll can only move at a slow speed, avoiding damage to the paper roll due to too fast discharging speed, or damaging the related equipment for transferring the paper roll.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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 embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] The facing paper on the front and back of the gypsum board is in a wound state before being used to hold the gypsum slurry, and it usually includes a paper roll 11 and a paper core 12 in its axis. The paper core 12 is in the shape of a hollow cylinder.

[0034] In the existing automatic paper splicing machine 1, the structures related to paper loading and unloading include paper roll supports 13. There are usually 2 paper roll supports 13, one of which is spare. When the paper roll 11 on one paper roll support 13 is in use, the paper roll 11 on the other paper roll support 13 is in a standby state. When the standby paper roll 11 is enabled, only the paper core 12 remains on the original paper roll support 13, and it needs to be removed and a new paper roll 11 needs to be replaced.

[0035] Figure 1 A mechanical schematic diagram showing the process of manually replacing the paper roll 11 is presented. A track 14 is provided below the paper roll support 13, and a track trolley 15 is installed on the track 14. The paper roll 11 is usually placed beside the track 14.

[0036] The paper roll 11 is pushed by the staff onto the track trolley 15, and then the track trolley 15 is moved through the track 14 so that the track trolley 15 and the paper roll 11 move near the paper roll support 13.

[0037] However, as mentioned above, the weight of the paper roll 11 is usually between 1 and 2 tons. Therefore, manual handling is extremely labor-consuming. When using mechanical equipment to handle the paper roll 11, it is difficult to handle the paper roll 11 stably because the material of the paper roll 11 is paper and it cannot be directly clamped, otherwise the surface is easily damaged. The only part of the paper roll 11 that can be clamped is the paper core 12. Moreover, the specifications of the paper rolls 11 stored in a warehouse are different. Therefore, it is difficult for automated equipment to accurately align with the paper core 12 and insert into it to clamp the paper roll 11, and the fully automated stereoscopic warehousing equipment is very likely to damage the paper roll 11 during discharging.

[0038] To solve the above technical problems, as Figures 2 - 5 shown, this specific embodiment provides a paper roll storage and feeding device for an automatic paper splicing machine to solve the above technical problems.

[0039] Its main structure includes: a paper roll storage 4 and a paper roll feeder 5.

[0040] The paper roll storage 4 is used to store the paper roll 11 and makes the stored paper roll 11 always have a tendency to roll in one direction;

[0041] The paper roll feeder 5 is arranged beside the paper roll storage 4 and is located in the rolling direction of the paper roll 11 stored in the paper roll storage 4. The paper roll feeder 5 is used to remove one paper roll 11 from the inside of the paper roll storage 4 at a time;

[0042] Among them, the paper roll feeder 5 includes a stop block 51, a third driver 52, a winding drum 53, a damper and a stop belt 54.

[0043] The stop block 51 blocks the rolling of the paper roll 11 stored in the paper roll storage 4 and has a discharge slope 511 that slopes downward in a direction away from the paper roll storage 4;

[0044] The third driver 52 is used to drive the stop block 51 to move vertically up and down so that the paper roll 11 stored in the paper roll storage 4 is blocked by the stop block 51 or rolls onto the discharge slope 511;

[0045] The winding drum 53 is rotatably connected to the frame or the stop block 51. The rotation axis of the winding drum 53 is horizontal and perpendicular to the rolling direction of the paper roll 11;

[0046] The damper (not shown in the figure) connects the winding drum 53 with the frame or the stop block 51, and the damper is used to reduce the rotation speed of the winding drum 53;

[0047] The stop belt 54 runs through the stop block 51 substantially vertically. One end of the stop belt 54 is detachably connected to the frame, and the other end of the stop belt 54 is wound around the winding drum 53 and fixedly connected to the winding drum 53.

[0048] The paper roll storage 4 is a storage rack made of steel structure. On the paper roll storage 4, there is a bearing plate 44 that slopes downward and abuts against the stop block 51. The bearing plate 44 is used to carry a plurality of paper rolls 11, and enables the plurality of paper rolls 11 to move towards the stop block 51 under the action of gravity. On both sides of the bearing plate 44, there are stop plates 45 for abutting against the end faces of the paper rolls 11.

[0049] The third driver 52 is a hydraulic system, which includes a guiding mechanism and a hydraulic cylinder. The hydraulic cylinder is used to drive the stop block 51 to move up and down, and the guiding mechanism is used to guide the moving direction of the stop block 51.

[0050] The damper can adopt various structures and methods to slow down the rotation speed of the winding drum 53, which will be described in detail later and will not be elaborated here.

[0051] The stop belt 54 is a woven belt.

[0052] The paper roll feeder 5 works in the following way to perform the work of removing one paper roll 11 from the inside of the paper roll storage 4 at a time:

[0053] S1. After the third driver 52 drives the stop block 51 to descend, the paper rolls 11 stored in the paper roll storage 4 roll towards the stop block 51, and one of the paper rolls 11 rolls onto the unloading slope 511. The paper roll 11 on the unloading slope 511 is blocked by the stop belt 54 and stops moving.

[0054] S2. After the third driver 52 drives the stop block 51 to rise, the paper rolls 11 stored in the paper roll storage 4 are blocked by the stop block 51, and the paper roll 11 on the unloading slope 511 has a tendency to roll in the direction away from the paper roll storage 4.

[0055] S3. Under the action of the damper, the winding drum 53 rotates slowly so that the stop belt 54 gradually elongates, and the paper roll 11 on the unloading slope 511 slowly rolls down from the unloading slope 511 until the paper roll 11 rolls onto the rail trolley 15, preventing the paper roll 11 from falling rapidly and damaging the rail trolley 15.

[0056] S4. Disconnect the connection between the stop belt 54 and the paper roll storage 4, the winding drum 53 winds up the stop belt 54 to separate the paper roll 11 from the stop belt 54, and then connect the stop belt 54 to the paper roll storage 4 again.

[0057] It should also be noted that:

[0058] The stop belt 54 can also provide a damping force to prevent the paper roll 11 from rolling down along the unloading slope 511 in other ways.

[0059] For example:

[0060] Both ends of the material stop belt 54 are fixedly connected to the frame. The material stop belt 54 can elastically expand and contract, and the downward rolling tendency of the paper roll 11 is hindered by the elastic force generated when the material stop belt 54 elongates.

[0061] Or,

[0062] One end of the material stop belt 54 is fixedly connected to the frame, and the other end of the material stop belt 54 is slidably mounted on the frame through a slider. There is a large frictional force between the slider and the frame, and this frictional force is sufficient to hinder the downward rolling tendency of the paper roll 11.

[0063] Furthermore:

[0064] A hook 41 is mounted on the frame. The material stop belt 54 is connected to the hook 41 through a hanging hole 541, and the hanging hole 541 is located at the end of the material stop belt 54.

[0065] Furthermore:

[0066] The hook 41 is connected to the frame through a first driver 42. The first driver 42 is used to drive the hook 41 to rotate so that the hook 41 can hook or release the hanging hole 541.

[0067] The first driver 42 can adopt devices such as a motor or a cylinder. The position of the first driver 42 on the paper roll storage 4 can be adjusted so that there is a distance for the paper roll 11 to pass between the hook 41 and the material stop block 51.

[0068] The opening of the hook 41 faces the rolling direction of the paper roll 11. When the first driver 42 drives the hook 41 to rotate towards the paper roll storage 4, the opening of the hook 41 moves downward and faces the rolling direction of the automatic paper splicing machine 1, so that the end of the material stop belt 54 is separated from the hook 41.

[0069] On the other hand:

[0070] The hook 41 is connected to the execution part of the first driver 42. The first driver 42 is connected to the execution part of a second driver (not shown in the figure), and the second driver is connected to the frame.

[0071] The first driver 42 is used to drive the hook 41 to rotate so that the hook 41 can hook or release the hanging hole 541.

[0072] The second driver is used to drive the first driver 42 to move so that the hook 41 approaches or moves away from the winding cylinder 53.

[0073] The second driver can adopt a servo electric push rod. The servo electric push rod is mainly used to drive the hook 41 to lift and lower so that the hook 41 approaches the winding cylinder 53, which is convenient for the staff to hang the hanging hole 541 on the hook 41, and then the second driver 43 drives the hook 41 to reset.

[0074] Furthermore:

[0075] This specific embodiment also provides an embodiment for automatically hooking the end of the material blocking belt 54 onto the hook 41.

[0076] The tape winding cylinder 53 is driven by a motor to rotate, and the tape winding cylinder 53 is in transmission connection with the output shaft of the motor;

[0077] The tape winding cylinder 53 is connected to the machine frame or the material blocking block 51 through a torque sensor 532, and the torque sensor 532 is used to detect the torque borne by the tape winding cylinder 53;

[0078] The material blocking belt 54 is wound by the tape winding cylinder 53, and when the tape winding cylinder 53 continues to wind, the hanging hole 541 performs a circular motion, and the movement track of the hanging hole 541 falls within the moving stroke of the hook 41.

[0079] The above embodiment is used to automatically hook the end of the material blocking belt 54 onto the hook 41, and the specific working steps of step S4 are as follows:

[0080] S41, the first driver 42 drives the hook 41 to rotate to disconnect the connection between the material blocking belt 54 and the machine frame, one end of the material blocking belt 54 is separated from the hook 41, and the tape winding cylinder 53 winds the material blocking belt 54 so that the paper roll 11 is separated from the material blocking belt 54.

[0081] S42, the second driver 43 drives the hook 41 to approach the tape winding cylinder 53, so that after the material blocking belt 54 is completely wound by the tape winding cylinder 53 and the tape winding cylinder 53 continues to rotate under the drive of the motor, the end of the material blocking belt 54 is swung by the tape winding cylinder 53, so that the hanging hole 541 performs a circular motion, and the hook 41 is located in the movement track of the hanging hole 541.

[0082] S43, the hanging hole 541 is hooked by the hook 41, the tape winding cylinder 53 immediately stops rotating, the torque borne by the tape winding cylinder 53 instantaneously increases due to the output of the motor, the torque sensor 532 sends a signal to the controller, the controller judges that the material blocking belt 54 is connected to the hook 41, the controller sends signals to the motor and the second driver 43, the motor stops working, and the second driver 43 drives the hook 41 to reset.

[0083] On the other hand:

[0084] The damper includes a motor, the tape winding cylinder 53 is in transmission connection with the output shaft of the motor, and the motor is used to drive or hinder the rotation of the tape winding cylinder 53.

[0085] The motor is a roller motor, which is built into the tape winding cylinder 53 and is not shown in the figure. The motor can output torque to the tape winding cylinder 53 to counteract the weight of the paper roll 11, thereby playing a role in reducing the rotation speed of the tape winding cylinder 53. At the same time, the motor can also retract the material blocking belt 54 after the paper roll 11 moves to the rail trolley 15.

[0086] Further:

[0087] The energy consumed by reducing the rotational speed of the winding cylinder 53 through the torque output by the motor is excessive.

[0088] For this reason, the damper further includes a brake 531, and the brake 531 is used to hinder the rotation of the winding cylinder 53.

[0089] The brake 531 is a disc brake. The brake 531 is installed on the rotating shaft of the winding cylinder 53. Compared with the motor, the energy consumed by the brake 531 to hinder the rotation of the winding cylinder 53 is less.

[0090] Further:

[0091] The damper further includes a torque sensor 532. The torque sensor 532 is connected to the winding cylinder 53 and the paper roll storage 4 or the material stop 51. The torque sensor 532 is used to detect the torque borne by the winding cylinder 53.

[0092] When the paper roll 11 moves onto the unloading slope 511, at this time the brake 531 is in a locked state, the retaining belt 54 is straightened, the winding cylinder 53 bears a large torque, and the controller judges that the paper roll 11 is on the unloading slope 511 through the signal sent by the torque sensor 532, and then the third driver 52 drives the material stop 51 to rise.

[0093] When the paper roll 11 moves onto the rail trolley 15, the retaining belt 54 is straightened, but the weight of the paper roll 11 is completely borne by the rail trolley 15, the winding cylinder 53 does not bear torque, the controller judges that the paper roll 11 is on the rail trolley 15 through the signal sent by the torque sensor 532, the staff unties the connection between the retaining belt 54 and the paper roll storage 4, and then the motor rotates the winding cylinder 53 to wind up the retaining belt 54 so that the paper roll 11 is separated from the retaining belt 54.

[0094] Further:

[0095] A rail trolley 15 is provided on the ground. The rail trolley 15 moves through the rail 14 and is arranged at the lowest point of the unloading slope 511.

[0096] During the process of pulling out the retaining belt 54 from the bottom of the paper roll 11, if the paper roll 11 does not roll, the paper roll 11 is likely to be damaged due to friction with the retaining belt 54. If the paper roll 11 rolls, the paper roll 11 is likely to roll off the rail trolley 15, and it still needs to be pushed back manually.

[0097] For this reason, the top of the rail trolley 15 is provided with a first roller 151 and a second roller 152. The first roller 151 and the second roller 152 are arranged side by side and are rotatably connected to the rail trolley 15.

[0098] The paper roll 11 falls from the discharging slope 511 onto the first roller 151 and the second roller 152. When the material blocking belt 54 is withdrawn, the paper roll 11 idles on the first roller 151 and the second roller 152.

[0099] Furthermore:

[0100] In the above embodiment, the paper roll feeder 5 is only applicable to providing the paper roll 11 to one track trolley 15. However, there are multiple automatic paper splicing machines 1 in a workshop, so there are also multiple tracks 14 and track trolleys 15. In order to enable the paper roll feeder 5 to provide the paper roll 11 to multiple track trolleys 15.

[0101] For this reason, as Figure 6 and 7 shown.

[0102] A track mother vehicle 16 is arranged on the ground. The track mother vehicle 16 moves through the mother vehicle track 17. The track 14 is perpendicular to the mother vehicle track 17. A sub-vehicle track 161 capable of being connected to the track 14 is arranged on the track mother vehicle 16.

[0103] The height of the sub-vehicle track 161 is equal to the height of the track 14. The track trolley 15 can travel on the track 14. And when the track 14 is connected to the sub-vehicle track 161, the track trolley 15 can move onto the track mother vehicle 16, so that the track trolley 15 can move along the mother vehicle track 17 to other tracks 14 through the track mother vehicle 16. Furthermore, 1 track mother vehicle 16 and 1 track trolley 15 can provide the paper roll 11 to multiple paper roll supports 13.

[0104] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention 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 invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the embodiments of the present invention.
