Description

Technical Field

[0001] This utility model relates to the field of automated production technology, specifically to a tilting and unloading mechanism. Background Technology

[0002] In automated production systems, belts, rollers, and tilting mechanisms are commonly used for automated loading and unloading. However, the tilting mechanism often needs to address the issue of securing the material trays. For example, patent application CN202120474384.6 discloses a tilting and dumping device for organic waste black soldier fly larvae breeding trays. In this device, the breeding trays delivered by the storage and retrieval equipment are supported by a frame and located between clamps on both sides of the frame. When it is necessary to dump the commercial larvae and insect sand from the breeding trays, the multiple claws included in the clamps are used to clamp the breeding trays, thereby preventing them from falling off during tilting. However, these clamps are classified as clamping mechanisms, and their operation requires the cooperation of a clamping cylinder and a guide rod linear bearing, which is not conducive to the structural simplification of automated production. Utility Model Content

[0003] In view of the problems existing in the prior art, the main objective of this utility model is to provide a flipping and unloading mechanism to solve one or more of the above-mentioned problems.

[0004] This utility model provides a flipping and unloading mechanism, comprising:

[0005] support;

[0006] A support platform, the first side of which is hinged to the bracket, so that the support platform is rotatably mounted on the bracket;

[0007] A side plate, which is connected to the first side of the support platform and protrudes from the platform surface;

[0008] The clamping component includes clamping claws located at the bottom of the support platform and away from the first side of the support platform; when the support platform and the bracket are in a parallel state, the head end of the clamping claw abuts between the support platform and the bracket, and its tail end does not protrude from the platform surface of the support platform; a torsion spring is engaged between the head end and the tail end of the clamping claw, so that when the platform surface of the support platform and the bracket are not parallel, the head end of the clamping claw can be separated from both the support platform and the bracket, and its tail end can extend out of the platform surface of the support platform to cooperate with the side plate to clamp the material tray.

[0009] As a further description of the above technical solution, the bracket is provided with a crossbeam, the crossbeam being away from the first side of the support platform. When the support platform and the bracket are in a parallel state, the front end of the clamping claw facing the bracket abuts against the crossbeam.

[0010] As a further description of the above technical solution, it also includes a cover plate connected to the support platform; the cover plate is connected to the second side of the support platform away from the side plate;

[0011] When the support platform and the bracket are in a parallel state, the cover plate covers the front end of the crossbeam and the clamping claw.

[0012] As a further description of the above technical solution, the cover plate has a relief portion cut out along its thickness direction, and the relief portion is used for the end of the clamping claw to pass through.

[0013] As a further description of the above technical solution, the support platform is connected to a drive source, which is used to drive the support platform to rotate relative to the bracket around a first side of the support platform.

[0014] As a further description of the above technical solution, the driving source is a bidirectional hydraulic cylinder.

[0015] As a further description of the above technical solution, it also includes a receiving box, which is located on the side of the side plate away from the support platform, and when the support platform is flipped to be above the receiving box, the angle formed between the platform surface of the support platform and the plane where the upper opening of the receiving box is located is less than 90°.

[0016] The beneficial effects of this utility model are as follows:

[0017] In the tilting and unloading mechanism provided by this utility model, a support platform rotatably mounted on a bracket is used to receive the material tray sent by the upstream equipment and continue to complete the unloading operation of the material in the tray. When the material tray is supported on the support platform, it is located between the side plate and the clamping member connected to the first side of the support platform. When the support platform and the bracket are in a parallel state, the head end of the clamping claw abuts against the support platform and the bracket, and its end does not protrude from the platform surface, thereby ensuring that the support platform receives the material tray without obstruction. A torsion spring is also engaged between the head and tail of the clamping claw. When the platform is not parallel to the support, i.e., during the rotation and lifting or lowering of the platform relative to the support, the external pressure on the torsion spring is released. This allows the head and tail of the clamping claw to spring outward, separating them from the platform and support. The tail, pressed by the torsion spring, pops off the platform and engages with the side plate to clamp the tray, ensuring it does not fall off the rotating platform. When the platform returns to the support, its weight presses down on the head of the clamping claw, causing the torsion spring to act in the opposite direction, releasing the clamping claw from the tray. Thus, the elasticity of the torsion spring and the weight of the platform itself are sufficient to clamp and release the tray, simplifying the overall mechanical structure of the tilting and unloading mechanism and eliminating the need for an additional power source.

[0025] Please see Figures 1 to 3This embodiment provides a tilting and unloading mechanism, which includes:

[0026] Bracket 1;

[0027] The support platform 2 is hinged to the bracket 1 on its first side, so that the support platform 2 is rotatably mounted on the bracket 1.

[0028] Side plate 3, the side plate 3 is connected to the first side of the support platform 2 and protrudes from the platform surface of the support platform 2;

[0029] The clamping component includes a clamping claw 4 located at the bottom of the support platform 2 and away from the first side of the support platform 2. When the support platform 2 and the bracket 1 are parallel, the head end 41 of the clamping claw 4 abuts against the support platform 2 and the bracket 1, and its tail end 42 does not protrude from the platform surface of the support platform 2. A torsion spring is engaged between the head end 41 and the tail end 42 of the clamping claw 4, so that when the platform surface of the support platform 2 and the bracket 1 are not parallel, the head end 41 of the clamping claw 4 is separated from both the support platform 2 and the bracket 1, and its tail end 42 can extend out of the platform surface of the support platform 2 and cooperate with the side plate 3 to clamp the material tray 9.

[0030] With the above structure, the support platform 2, rotatably mounted on the support 1, is used to receive the material tray 9 sent from the upstream equipment and to continue the pouring operation of the material in the material tray 9. When the material tray 9 is supported on the support platform 2, it is located between the side plate 3 connected to the first side of the support platform 2 and the clamping member. When the support platform 2 and the support 1 are in a parallel state, the head end 41 of the clamping claw 4 abuts against the support platform 2 and the support 1, and its end 42 does not protrude from the table surface of the support platform 2, thereby ensuring that the support platform 2 receives the material tray 9 without obstruction. A torsion spring is also engaged between the first end 41 and the last end 42 of the clamping claw 4. When the platform of the support 2 is not parallel to the support 1, that is, during the process of the support 2 rotating and rising or falling relative to the support 1, the external pressure on the torsion spring is released, so that the first end 41 of the clamping claw 4 can be pushed outward to separate from the support 2 and the support 1. Its last end 42 can be pushed out of the platform of the support 2 by the spring and cooperate with the side plate 3 to clamp the tray 9, ensuring that the tray 9 will not fall off the rotating support 2. After the support 2 falls back to the support 1, its weight presses down on the first end 41 of the clamping claw 4, so that the torsion spring is subjected to its gravity and acts in the opposite direction on the first end 42 of the clamping claw 4, thereby releasing the clamping claw 4 from the clamping and fastening effect on the tray 9. Therefore, the elasticity of the torsion spring and the weight of the support platform 2 itself can ensure the locking or releasing of the material tray 9, simplifying the overall mechanical structure of the flipping and unloading mechanism and eliminating the need for an additional power source. It should be understood that the material tray 9 has a wall portion that abuts against the side plate 3 and the end 42 of the clamping claw 4.

[0031] Specifically, in this embodiment, the support 1 is provided with a crossbeam 5. The crossbeam 5 is located away from the first side of the support platform 2. When the support platform 2 and the support 1 are in a parallel state, the weight of the support platform 2 is borne by the torsion spring and the clamping claw 4 simultaneously, which is sufficient to make the front end 41 of the clamping claw 4 abut against the crossbeam 5 on the side facing the support 1, thereby releasing the clamping and fastening effect of the end 42 of the clamping claw 4 on the material tray 9.

[0032] Specifically, in this embodiment, the flipping and unloading mechanism further includes a cover plate 6 connected to the support platform 2; the cover plate 6 is connected to the second side of the support platform 2 away from the side plate 3; when the support platform 2 and the bracket 1 are in a parallel state, the cover plate 6 covers the front end 41 of the crossbeam 5 and the clamping claw 4, and also avoids the crossbeam 5 or the clamping claw 4 from interfering with the upstream equipment when the support platform 2 receives the material tray 9 from its side away from the side plate 3.

[0033] Specifically, in this embodiment, the shield 6 has a relief portion 61 cut out along its thickness direction. The relief portion 61 is used for the end 42 of the clamping claw 4 to pass through, so that it can protrude from the table surface of the support platform 2 to cooperate with the side plate 3 to clamp and fasten the material tray 9, and smoothly reverse and reset to the bottom of the support platform 2.

[0034] Specifically, in this embodiment, the support platform 2 is connected to a drive source 7. The drive source 7 is used to drive the support platform 2 to rotate relative to the support 1 around the first side of the support, so that it can be horizontally supported on the support 1 to receive the material tray 9 sent from the upstream equipment, and to rotate to a position that allows the material in the material tray 9 to be completely emptied. More specifically, the drive source 7 is a bidirectional hydraulic cylinder. The advantage is that when the bidirectional hydraulic cylinder is lifted, the lever arm is at its maximum, reducing the torque at startup, which is conducive to driving the support platform 2 to rotate to a specified angle. At the same time, the cylinder stroke is at its maximum. After pausing for a few seconds to allow the material in the material tray 9 to be emptied, the bidirectional hydraulic cylinder is then activated to cause the support platform 2 to rotate in the opposite direction and return to its original position, thus removing the empty material from the empty material tray 9.

[0035] Specifically, in this embodiment, a receiving box 8 is also included. The receiving box 8 is located on the side of the side plate 3 away from the support platform 2. When the support platform 2 is flipped over to the top of the receiving box 8, the angle formed between the platform surface of the support platform 2 and the plane where the upper opening of the receiving box 8 is located is less than 90°. The purpose is to ensure that the material in the material tray 9 can be completely poured out.

[0036] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
