Description

Technical Field

[0001] The present invention relates to the technical field of fixtures, and particularly to a rolling curtain type robot fixture. Background Art

[0002] In product palletizing, it is necessary to use a fixture to clamp the packaging box containing the product and then move the packaging box to the palletizing area for placement. When the palletized product is heavy, such as an installation box containing bottled wine, in order to ensure the stability of clamping the installation box, a fixture that can support the installation box is generally used. For example, a public document of a whole-layer palletizing fixture with the publication number CN210285976U discloses such a fixture that can lift the packaging box, which specifically includes components such as a mounting frame, a rotating shaft 6, a first sprocket 5, and a first gear 3;

[0003] However, this fixture has certain limitations during use. For example, when the chain pulls the roller to move and opens the area below the fixture to cause the packaging box to lose support and fall onto the palletizing area, due to the presence of the roller, there is a gap between the packaging box and the palletizing area, which will cause the packaging box to directly fall onto the packaging area with a certain impact force, causing the product in the packaging box to be impacted and easily damaging the packaging bottles in the packaging box, and also easily damaging the packaging box. Summary of the Invention

[0004] The purpose of the present invention is to provide a rolling curtain type robot fixture to solve the problem that there is a gap between the packaging box and the palletizing area, which will cause the packaging box to directly fall onto the packaging area with a certain impact force as mentioned in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A rolling curtain type robot fixture, including: a bracket, two groups of chains are arranged on the bracket and a driving mechanism for driving the chains to move along the edge of the bracket, rollers located below the bracket are arranged on both groups of the chains, a blocking frame and a driving member for driving the blocking frame to flip are arranged at the feeding port of the bracket, clamping plates are arranged on both sides of the bracket and a telescopic mechanism for driving the clamping plates to move to clamp the packaging box, and the robot fixture further includes: a pressing plate arranged on the side of the clamping plate facing the packaging box;

[0006] A downwardly extending chute is formed on the side of the clamping plate facing the pressing plate, and a sliding block slidably inserted into the chute is arranged on the pressing plate;

[0007] Wherein, a baffle plate that fits with the sliding block is arranged in the chute, and the lower direction of the baffle plate inclines towards the pressing plate, so that the distance between the baffle plate and the pressing plate gradually decreases from top to bottom, increasing the pressure of the contact between the sliding block and the baffle plate when the sliding block moves downward, increasing the frictional resistance received by the sliding block when moving downward, and reducing the descending speed of the pressing plate and the packaging box.

[0008] Preferably, the slider includes a mounting block, a moving block slidably disposed on the mounting block, and an elastic member disposed between the moving block and the mounting block.

[0009] Preferably, the upper part of the baffle is hinged to the inner wall of the chute. A moving member extending below the clamping plate is slidably disposed in the chute. A rotating rod is rotatably disposed in the chute. A first gear and a second gear are disposed on the rotating rod. A rack meshing with the first gear is disposed on one side of the moving member facing the rotating rod. A toothed groove plate meshing with the second gear and used for pushing the baffle to rotate is slidably disposed in the chute.

[0010] Preferably, a plurality of groups of stoppers are disposed on the toothed groove plate. A limiting member for inserting between adjacent stoppers is slidably disposed in the chute. A connecting rope is disposed between the limiting member and the chain.

[0011] Preferably, the baffle includes a support plate, a movable plate, and an elastic element installed between the support plate and the movable plate; a plurality of groups of resistance blocks are disposed on one side of the support plate facing the movable plate, and openings corresponding to the resistance blocks are formed on the movable plate.

[0012] Preferably, an installation hole is formed below the moving member, and an expansion member is slidably inserted into the installation hole.

[0013] Preferably, a slot is formed on one side of the pressing plate facing the packaging box. A sliding member in the same direction as the roller transmission direction is slidably disposed in the slot. A placement groove is formed on one side of the sliding member away from the pressing plate. A clamping block and a spring connected to the clamping block are slidably inserted into the placement groove. Push blocks for pushing the clamping block to move are slidably inserted into both sides of the inner cavity of the slot.

[0014] Preferably, two touch switches are installed on both sides of the sliding member in the inner cavity of the slot. The touch switches are electrically connected to a PLC controller, and the PLC controller is electrically connected to a telescopic mechanism.

[0015] Preferably, a stop bar for restricting the position of the packaging box and a telescopic member for driving the stop bar to move are disposed in the bracket.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: In this application, through the restriction of the baffle, when the pressing plate and the slider fall with the packaging box, the moving block will move closer to the mounting block, compressing the elastic member, increasing the pressure of the contact between the slider and the baffle, thereby increasing the frictional force of the contact between the two, increasing the resistance of the slider to move downward, reducing the speed of the pressing plate and the packaging box descending, reducing the impact force when the packaging box falls onto the stacking area, and protecting the packaging box and the products in the packaging box.

Specific embodiments

[0025] 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. 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.

[0026] Embodiment 1:

[0027] Please refer to Figure 1, A rolling curtain type robot fixture, comprising: a bracket 1, on which two groups of chains 2 are symmetrically arranged, a driving mechanism 4 is installed on the bracket 1, and an output shaft of the driving mechanism 4 is connected to the chain 2 for driving the chain 2 to move along the edge of the bracket 1; rollers 3 are arranged on both groups of chains 2, and the two rollers 3 are symmetrically distributed below the bracket 1; a blocking frame 5 is hinged on the feeding port of the bracket 1, and a driving member is arranged on the bracket 1, and the driving member is connected to the blocking frame 5 for driving the blocking frame 5 to flip; telescopic mechanisms 7 are arranged on both sides of the bracket 1, and clamping plates 6 are installed on the moving ends of the telescopic mechanisms 7, and the clamping plates 6 are located inside the bracket 1 for driving the clamping plates 6 to move to clamp the packing box. The setting direction of the clamping plates 6 is perpendicular to that of the rollers 3, and the moving direction of the clamping plates 6 is perpendicular to the moving direction of the rollers 3.

[0028] In this embodiment, as Figure 1 described, a stop bar 9 is arranged inside the bracket 1, and a telescopic member is arranged on the bracket 1, and the moving end of the telescopic member is connected to the stop bar 9 for driving the stop bar 9 to move; the stop bar 9 faces the blocking frame 5, and when the packing box is transmitted above the roller 3, its moving position is restricted by the stop bar 9.

[0029] Please refer to Figure 1 and Figure 2 , a pressing plate 8 is arranged on one side of the clamping plate 6 facing the packing box; a sliding groove 11 is formed on one side of the clamping plate 6 facing the pressing plate 8, a sliding block 10 is arranged on the pressing plate 8, and the sliding block 10 is slidably inserted into the sliding groove 11 and can move up and down in the sliding groove 11; a baffle 12 is arranged in the sliding groove 11, one side of the baffle 12 facing the pressing plate 8 is attached to the sliding block 10, and the lower direction of the baffle 12 inclines towards the pressing plate 8;

[0030] wherein, the sliding block 10 includes a mounting block 103, a moving block 101 slidably arranged on the mounting block 103, and an elastic member 102 arranged between the moving block 101 and the mounting block 103.

[0031] In summary, the working principle of the fixture is as follows: The robot moves the fixture to the packaging box transfer area (where the packaging box contains goods) and aligns it there; then the driving member operates to rotate the blocking frame 5, opening the feed inlet of the support 1, allowing the packaging box to be transferred onto the roller 3, and the roller 3 rotates to transfer the packaging box into the support 1; the driving member drives the blocking frame 5 to rotate in the reverse direction to close the feed inlet of the support 1; the telescopic mechanism 7 drives the clamping plate 6 to approach the packaging box, making the pressing plate 8 contact the packaging box and pushing the packaging box to move (adjusting the position of the packaging box inside the support 1 and clamping the packaging box); then the robot moves the fixture. When the fixture is moved to the palletizing area, the driving mechanism operates to drive the chain 2 to move the roller 3, causing the two groups of rollers 3 to move away from each other (moving along the edge of the support 1), opening the lower part of the support 1; the goods lose the support of the roller 3 and fall, driving the pressing plate 8 to move downward together, causing the slider 10 to move downward in the chute 11. Due to the limitation of the baffle 12 (the distance between the baffle 12 and the pressing plate 8 gradually decreases from top to bottom), the moving block 101 will approach the mounting block 103, compressing the elastic member 102, increasing the pressure of the contact between the slider 10 and the baffle 12 (i.e., increasing the friction force between the two), increasing the resistance of the slider 10 to move downward, which is used to reduce the falling speed of the pressing plate 8 and the packaging box, thereby reducing the impact force when the packaging box falls onto the palletizing area.

[0032] Embodiment 2:

[0033] Please refer to Figure 2 and Figure 3, the upper part of the baffle 12 is hinged to the inner wall of the chute 11. A moving member 13 is slidably arranged in the chute 11, and the moving member 13 extends below the baffle 12 (the moving member 13 can move up and down). A rotating rod is rotatably arranged in the chute 11, and a first gear 14 and a second gear 16 are arranged on the rotating rod. A rack 15 meshing with the first gear 14 is arranged on one side of the moving member 13 facing the rotating rod. A toothed groove plate 17 meshing with the second gear 16 is slidably arranged in the chute 11 (the toothed groove plate 17 moves closer to or away from the pressing plate 8 when moving); when the fixture moves to the palletizing area, the moving member 13 contacts the upper part of the palletizing area (this is the palletizing area of the goods). According to the distance between the fixture and the palletizing area, the moving member 13 will move up and down, driving the first gear 14 to rotate, driving the rotating rod and the second gear 16 to rotate together, making the toothed groove plate 17 move, pushing the baffle 12 to move, and changing the distance between the baffle 12 and the pressing plate 8; when the distance between the fixture and the palletizing area is large, the length of the moving member 13 below the clamping plate 6 is more, which will make the toothed groove plate 17 push the baffle 12 closer to the pressing plate 8, increasing the inclination amplitude of the baffle 12 (the distance between the baffle 12 and the pressing plate 8 becomes smaller downward), further increasing the resistance to the downward movement of the slider 10; conversely, when the distance between the fixture and the palletizing area decreases, the inclination amplitude of the baffle 12 is smaller, which is used to reduce the resistance to the downward movement of the slider 10, so that the falling speed of the packaging box can be adjusted according to the distance between the fixture and the palletizing area.

[0034] In this embodiment, as Figure 2 and Figure 3 shown, several groups of stoppers 18 are arranged on the toothed groove plate 17, and a limiting member 19 is slidably arranged in the chute 11. A connecting rope is arranged between the limiting member 19 and the chain 2; when the driving mechanism 4 drives the chain 2 and the roller 3 to move and opens the lower part of the bracket 1, the connecting rope will also be pulled, making the limiting member 19 move and insert between the stoppers 18 to block the movement of the toothed groove plate 17, thereby restricting the position of the baffle 12 and ensuring that the baffle 12 will not move when the slider 10 moves downward and presses the baffle 12.

[0035] In this embodiment, as Figure 2 and Figure 4 shown, the baffle 12 includes a support plate 121, a movable plate 122, and an elastic element installed between the support plate 121 and the movable plate 122. The movable plate 122 can move closer to the support plate 121; several groups of resistance blocks 123 made of rubber are arranged on one side of the support plate 121 facing the movable plate 122, and openings corresponding to the resistance blocks 123 are formed on the movable plate 122 (the movable plate 122 is in contact with the slider 10); during the downward movement of the slider 10, the baffle 12 will be pressed, making the movable plate 122 move closer to the support plate 121, making the resistance blocks 123 move towards or pass through the openings (will contact the slider 10), playing an effect of hindering the downward movement of the slider 10, being used to reduce the falling speed of the slider 10, and further reducing the falling speed of the packaging box.

[0036] In this embodiment, as Figure 7 shown, an installation hole is provided below the moving member 13, and an expansion member 131 is slidably inserted into the installation hole. A bolt for fixing the expansion member 131 is screwed on the moving member 13; the length of the moving member 13 is increased by the expansion member 131, and the bolt is loosened, and the expansion member 131 is moved up and down to adjust the length of the expansion member 131 outside the outside.

[0037] Embodiment 3:

[0038] Please refer to Figure 5 and Figure 6 , a slot 20 is provided on one side of the pressing plate 8 facing the packaging box. A sliding member 21 is slidably provided in the slot 20 (the sliding member 21 moves left and right in the inner cavity of the slot 20, parallel to the transmission direction of the roller 3). An accommodation groove is provided on the side of the sliding member 21 away from the pressing plate 8. A clamping block 22 is slidably inserted into the accommodation groove, and a spring is installed between the accommodation groove and the clamping block 22; Push blocks 23 are slidably inserted into both the left and right sides of the inner cavity of the slot 20 (a return spring is installed between the push block 23 and the slot 20 to reset the moved push block 23); the telescopic mechanism 7 drives the clamping plate 6 and the pressing plate 8 to move, so that after the pressing plate 8 contacts the packaging box (the clamping block 22 also contacts the packaging box), when the roller 3 moves to open the lower part of the bracket 1, if the clamping force of the pressing plate 8 on the packaging box is relatively tight, the packaging box will not move with the roller 3; on the contrary, if the clamping force of the pressing plate 8 on the packaging box is relatively loose, it will cause the packaging box to move with the roller 3 (it will cause the pressing plate 8 not to clamp the packaging box. When the packaging box falls, the pressing plate 8 will not move down, resulting in the inability to control the falling speed of the packaging box), and at the same time, the movement of the packaging box will cause the clamping block 22 to drive the sliding member 21 to slide in the slot 20; make the push block 23 contact the inner wall of the slot 20, squeeze the push block 23 into the accommodation groove, and push the clamping block 22 towards the packaging box to increase the clamping force of the clamping block 22 on the packaging box (fix the packaging box and prevent it from continuing to move with the roller 3), so that the pressing plate 8 can move down with the packaging box when the packaging box moves down.

[0039] In this embodiment, as Figure 5 shown, two touch switches 24 are installed in the inner cavity of the slot 20. The two touch switches 24 are respectively located on both sides of the sliding member 21. The touch switch 24 is electrically connected to a PLC controller (model number TPC24-24TD), and the PLC controller is electrically connected to the telescopic mechanism 7; when the packaging box moves with the roller 3, the sliding member 21 will squeeze the touch switch 24. After the PLC controller receives the information, it controls the telescopic mechanism 7 to work, so that the clamping plate 6 and the pressing plate 8 move towards the packaging box to fix the packaging box and prevent it from moving with the roller 3, and the pressing plate 8 can move with the packaging box when the packaging box moves down.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
