Description

Technical Field

[0001] The invention relates to the field of gypsum board stacking, and in particular to a reversible gypsum board aligning device. Background Art

[0002] In the stacking process of gypsum boards, the gypsum boards are transported from the conveyor belt to the stacker. When the gypsum boards move to the end of the conveyor belt, they fly over the gap between the conveyor belt and the stacker under the action of inertia and gravity and move to the stacker. Since the transfer process of the gypsum boards is unstable, the edges of the gypsum boards on the stacker cannot be aligned, and the gypsum boards need to be aligned later.

[0003] The related technology of the gypsum board stacking device involved in the subject matter disclosed in the present invention is disclosed in: Chinese Patent Publication No. CN113443446A discloses an automatic stacking device for gypsum boards, which discloses a technical solution for automatically stacking gypsum boards and pushing the gypsum boards on the stacking platform during the stacking process to align multiple layers of gypsum boards.

[0004] Alignment devices are usually set on both sides of the stacker to align the two sides of the gypsum board. Similarly, the position corresponding to the stop plate set at the far end of the stacker also requires an alignment device. However, the alignment device located at the near end of the stacker needs to be able to avoid the gypsum board being transported during operation. The faster the transmission speed of the gypsum board and the higher the stacking efficiency, the higher the requirements for the working speed and response time of the gypsum board alignment device. The existing alignment device is gradually unable to adapt to the high-speed production of gypsum boards.

[0005] The present invention is intended to provide a gypsum board aligning device that is different from the prior art, so as to align the edges of the gypsum boards during the stacking process without hindering the loading of the next gypsum board. Summary of the Invention

[0009] Furthermore, rollers are installed on both sides of the sliding seat, and the wheel surfaces of the rollers abut against the support seat to support the weight of the sliding seat.

[0014] Furthermore, the rotating shaft is connected to the support seat through a bearing seat.

[0015] Furthermore, a mounting hole for mounting a spring plunger is formed on the outer circumferential surface of the inner shaft, the spring plunger is screwed to the mounting hole, and the ball head of the spring plunger is exposed outside the circumferential surface of the inner shaft to form the slider.

[0016] Furthermore, the outer shaft has an axial hole axially passing through its axis, the axial hole is transitionally connected to the inner shaft, and an annular flange extending radially inward is formed inside the axial hole. The annular flange is connected to the inner shaft through a fastener, and the annular flange does not contact the inner shaft, so that the inner shaft can rotate inside the axial hole and slide within a certain stroke.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] This specific implementation provides Example 1, please refer to Figure 1-3 The gypsum board is transported to the stacking platform 400 through the conveyor 300. A baffle 200 is provided on the side of the stacking platform 400 away from the conveyor 300. The position of the baffle 200 is fixed. The baffle 200 is used to block the movement of the gypsum board so that the gypsum board stops moving when it hits the baffle 200 on the stacking platform 400. Aligning the gypsum boards means aligning the edges of each gypsum board on the stacking platform 400 with the baffle 200.

[0033] The aligning device 100 includes:

[0034] The support base 1 is mounted on the frame and is used to install the pushing cylinder 10 and the guide rail 11. The pushing direction of the pushing cylinder 10 is parallel to the direction in which the gypsum board moves from the conveyor 300 to the stacking platform 400. The extending direction of the guide rail 11 is parallel to the pushing direction of the pushing cylinder 10.

[0035] The sliding seat 7 is slidably connected to the support seat 1 through the guide rail 11, and the sliding seat 7 is transmission-connected to the actuator of the push cylinder 10 so that the push cylinder 10 can push the sliding seat 7 to slide along the guide rail 11;

[0036] Rollers 12 are mounted on both sides of the sliding seat 7, and the wheel surfaces of the rollers 12 abut against the support seat 1, so that most of the weight of the sliding seat 7 is borne by the rollers 12, thereby reducing the sliding friction between the sliding seat 7 and the guide rail 11;

[0037] The swing arm 3 is swingably connected to the support base 1 via a swing cylinder 9 and is on standby in the gap between the conveyor 300 and the stacking platform 400. The swing cylinder 9 is used to drive the swing arm 3 to swing so that the swing arm 3 can stop in two positions. One position allows the swing arm 3 to push the gypsum board to align with other gypsum boards on the stacking platform 400 under the drive of the pushing cylinder 10, and the other position allows the swing arm 3 to avoid the gypsum board moving from the conveyor 300 to the stacking platform 400.

[0038] A nylon plate 6 is provided on the side of the swing arm 3 facing the stacking platform 400 to replace part of the swing arm 3 to prevent the swing arm 3 from being worn during repeated pushing of the gypsum boards. The worn nylon plate 6 can be replaced at any time to prevent the gaps in the worn nylon plate 6 from damaging the side walls of the gypsum boards during the pushing process. The length of the nylon plate 6 is greater than the thickness of the two gypsum boards so that the nylon plate 6 can contact the two gypsum boards simultaneously during operation, thereby aligning one gypsum board with the other.

[0039] The rotating shaft 4 is rotatably connected to the support base 1 through the bearing base 2 fixedly mounted on the support base 1. The axis of the rotating shaft 4 is parallel to the direction in which the gypsum board moves from the conveyor 300 to the stacking platform 400. One end of the rotating shaft 4 is coaxially connected to the actuator of the swing cylinder 9 through the coupling 8. The other end of the rotating shaft 4 is fixedly connected to one end of the rocker arm 3 through the expansion sleeve 5. The rotating shaft 4 is used to bear the weight of the rocker arm 3 and the torque generated by the other end of the rocker arm 3 when one end of the rocker arm 3 pushes the gypsum board, so as to avoid damage to the rocker cylinder 9.

[0040] The working steps of the aligning device 100 are as follows:

[0041] In step 1, when the gypsum board moves from the conveyor 300 to the stacking platform 400, the actuator of the push cylinder 10 is located at the end away from the stacking platform 400, and the swing cylinder 9 drives the rocker arm 3 to maintain a horizontal posture to avoid the gypsum board.

[0042] In step 2, after the gypsum board falls on the stacking platform 400, the swing cylinder 9 drives the rocker arm 3 to move to a vertical position, so that the rocker arm 3 can contact the side wall of the gypsum board on the stacking platform 400 through the push of the push cylinder 10, and then push the gypsum board on the stacking platform 400 to a position aligned with other gypsum boards.

[0043] In step three, the swing cylinder 9 drives the rocker arm 3 to move to a horizontal position to avoid the next gypsum board transmitted to the stacking platform 400, and in the process of the gypsum board moving from the conveyor 300 to the stacking platform 400, the cylinder 10 is pushed to drive the rocker arm 3 to reset.

[0044] Compared with other existing alignment devices, the gypsum board in Example 1 does not need to wait for the rocker arm 3 to reset. The gypsum board on the conveyor 300 can move toward the stacking platform 400 while the rocker arm 3 pushes another gypsum board. As long as the other gypsum board is aligned and the rocker arm 3 is rotated to a horizontal position before the gypsum board contacts the rocker arm 3, Example 1 can adapt to the high-speed production of gypsum boards.

[0045] For further information, please refer to Figure 4 .

[0046] The aligning device 100 is suspended between the conveyor 300 and the stacking platform 400 by a crossbeam 500. The crossbeam 500 is arranged horizontally and perpendicular to the direction in which the gypsum board moves from the conveyor 300 to the stacking platform 400. The aligning device 100 has multiple ones and is arranged at equal or unequal intervals along the length direction of the crossbeam 500.

[0047] Different aligning devices 100 work selectively according to the side length of the gypsum board. When the side of the gypsum board perpendicular to its moving direction is shorter, fewer aligning devices 100 work, and when the side of the gypsum board perpendicular to its moving direction is longer, more aligning devices 100 work.

[0048] Further:

[0049] In Example 1, after the rocker arm 3 pushes the gypsum board into alignment, the nylon board 6 always rubs against the side wall of the gypsum board during the process of the rocker arm 3 rotating from the vertical posture to the horizontal posture, which easily causes wear on the surface of the nylon board 6 and the side wall of the gypsum board.

[0050] In order to solve the above technical problems, based on Example 1, this specific implementation method also provides Example 2, please refer to Figure 5-8 .

[0051] The rotating shaft 4 includes:

[0052] The inner shaft 13 is fixedly connected to the rocker arm 3 via the expansion sleeve 5. The outer circumferential surface of the inner shaft 13 is formed with a mounting hole 15 for mounting a spring plunger 14. The spring plunger 14 is screwed to the inner shaft 13 through the mounting hole 15, and only the ball head of the spring plunger 14 is exposed outside the circumferential surface of the inner shaft 13.

[0053] The outer shaft 16 has one end connected to the inner shaft 13 through the shaft hole 17 and the other end fixedly connected to the actuator of the swing cylinder 9 through the coupling 8. The inner shaft 13 and the outer shaft 16 form a cylindrical pair so that the inner shaft 13 can rotate or move axially in the shaft hole 17;

[0054] An annular flange 18 extending radially inward is formed inside the shaft hole 17. A first bolt 19 passes through the annular flange 18 and is screwed into a threaded hole 20 formed on the end surface of the inner shaft 13. This limits the axial movement of the inner shaft 13 within the shaft hole 17. That is, the inner shaft 13 can move approximately 5 mm along the axis of the shaft hole 17.

[0055] The inner circumference of the shaft hole 17 is further formed with a spiral groove 21 that spirally extends around its own axis. The spiral groove 21 is slidably connected to the ball head of the spring plunger 14. The spiral groove 21 occupies a central angle of approximately 10° on the circumference of the shaft hole 17 and extends in a direction away from the inner shaft 13.

[0056] An end cover 22 is installed at the end of the outer shaft 16 close to the rocker arm 3. The end cover 22 is screwed to the flange 24 at the end of the outer shaft 16 through a second bolt 23. The end cover 22 is used to cover the connection between the spiral groove 21 and the end of the outer shaft 16 to prevent the ball head of the spring plunger 14 from detaching from the spiral groove 21.

[0057] The working steps of Example 2 are as follows.

[0058] Step 1: The swing cylinder 9 drives the outer shaft 16 to rotate 100 degrees, so that the swing arm 3 rotates from a vertical posture to a horizontal posture:

[0059] When the outer shaft 16 rotates 0° to 10°, the rocker arm 3 remains vertical under the action of its own weight. At this time, the inner shaft 13 does not rotate, and the ball head of the spring plunger 14 slides inside the spiral groove 21, so that the inner shaft 13 moves axially to approach the outer shaft 16, that is, the inner shaft 13 moves linearly in a direction away from the gypsum board and thus separates from the gypsum board. The nylon board 6 does not rub against the side wall of the gypsum board during the movement.

[0060] When the outer shaft 16 rotates 10° to 100°, the ball head of the spring plunger 14 has slid to the end point in the spiral groove 21. When the outer shaft 16 rotates, it drives the inner shaft 13 to rotate together, so that the pendulum 3 swings 90 degrees, and then rotates from a vertical position to a horizontal position.

[0061] In step 2, the swing cylinder 9 drives the outer shaft 16 to rotate 100°, so that the rocker arm 3 rotates from a horizontal posture to a vertical posture, and the inner shaft 13 returns to a position away from the outer shaft 16 through the spring plunger 14 and the spiral groove 21.

[0062] Optionally:

[0063] Through Example 1, Example 3 can also be easily obtained. Example 3 is not shown in the figure. It is only necessary to exchange the connection relationship between the pushing cylinder 10 and the swing cylinder 9 in Example 1, that is: use the swing cylinder 9 to drive the pushing cylinder 10 to rotate, and use the pushing cylinder 10 to drive the rocker arm 3 to move back and forth in a straight line. The specific structure will not be repeated here.

The scope of protection of the present invention is defined by the claims.
