Description

Technical Field

[0001] This utility model relates to the field of waste sorting technology, specifically to a waste bag grabbing device for a waste sorting system. Background Technology

[0002] With the continuous advancement of waste sorting policies, various types of household waste will be sorted by the waste sorting system before further processing. In daily life, waste is often disposed of together with the garbage bags. Therefore, waste sorting systems are generally equipped with bag-breaking mechanisms. After the garbage bags are broken open by the bag-breaking mechanism, the garbage bags and waste are transferred to the surface of the conveyor for transportation and further processing.

[0003] In addition to sorting and recycling the waste itself, garbage bags also have recycling value. Therefore, traditional waste sorting systems also have special garbage bag recycling programs, such as the technical solutions described in Chinese invention patents: application number 202110520453.7 (application date: May 13, 2021), entitled "Intelligent Waste Sorting Equipment and Control Method Thereof"; application number 202211574073.2 (application date: December 8, 2022), entitled "Garbage Bag Breaking and Recycling Device"; application number 202111246922.7 (application date: October 26, 2021), entitled "Automatic Waste Sorting Equipment and Method of Use Thereof"; and application number 202010924333.9 (application date: September 4, 2020), entitled "A Fully Automatic Waste Sorting and Recycling Equipment".

[0004] In the above solutions, garbage bags are typically gripped by a clamp or similar device after contact with the bag. The gripping direction is generally from top to bottom. In practice, a vertical guiding mechanism (such as a guide rail) is usually required, or the vertical movement of the clamp can be achieved directly through a cylinder. The drawback of this approach is that it increases the complexity of the structure to some extent and occupies too much vertical space within the system. Furthermore, when vertical movement is achieved solely through a cylinder, the stability is poor. Since garbage bags are made of flexible material, it is sometimes impossible to reliably grip them. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a garbage bag grabbing device for a garbage sorting system that is set at the lower part of the translation vehicle in a swing manner. Compared with the vertically running grabbing mechanism in the prior art, it reduces the occupation of vertical space and improves the stability and reliability of garbage bag grabbing.

[0006] The technical solution adopted by this utility model to solve its technical problem is: the garbage bag grabbing device of the garbage sorting system includes a guide rail frame, a guide rail is provided in the guide rail frame, and a reciprocating clamping mechanism is provided on the guide rail. The feature is that: a reciprocating translation vehicle is provided on the guide rail, and a swinging mechanism is provided at the lower part of the translation vehicle. The clamping mechanism is installed at the end of the swinging mechanism.

[0007] Preferably, a reciprocating gripping vehicle is also provided inside the translation vehicle, the direction of movement of the gripping vehicle is perpendicular to the direction of movement of the translation vehicle, and the swing mechanism is installed at the lower part of the gripping vehicle.

[0008] Preferably, the swing mechanism includes an extension frame vertically fixed to the lower part of the gripping vehicle, a folding frame hinged to the bottom of the extension frame, the extension frame and the folding frame being connected by a swing cylinder, and the gripping mechanism being a clamping plate installed at the end of the folding frame.

[0009] Preferably, a translation cylinder is provided on the upper part of the translation vehicle, and the piston rod of the translation cylinder is connected to the gripping vehicle.

[0010] Preferably, a translation drive mechanism is provided at the end of the guide rail, and the translation drive mechanism is connected to the translation vehicle through a synchronous belt mechanism.

[0011] Preferably, a mounting plate is provided at the end of the folding frame, a gripping cylinder is mounted on the surface of the mounting plate, and a clamping plate is mounted on the gripper of the gripping cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In the garbage bag grabbing device of the garbage sorting system of this application, the gripping mechanism is set at the lower part of the translation vehicle in a swinging manner. Compared with the vertically operating gripping mechanism in the prior art, it reduces the occupation of vertical space and improves the stability and reliability of garbage bag gripping.

[0014] The translating vehicle is also equipped with a gripping vehicle, and the gripping mechanism is installed at the bottom of the gripping vehicle. Therefore, when gripping the garbage bag, the gripping mechanism moves relative to the garbage bag in the horizontal direction while tilted, which further improves the reliability of gripping the garbage bag.

[0015] Limit switches are installed at both ends of the guide rail to limit the translation mechanism and prevent it from moving beyond the limit. Attached Figure Description

Detailed Implementation

[0020] Figures 1-3 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-3 The present invention will be further described below.

[0021] like Figures 1-3 As shown, a garbage bag grabbing device for a garbage sorting system includes a guide rail frame 4, within which a set of parallel guide rails 5 are arranged. A translation mechanism is arranged between the two guide rails 5, and the translation mechanism reciprocates along the guide rails 5. A grabbing mechanism is arranged below the translation mechanism. The grabbing mechanism moves with the translation mechanism to the conveyor, removes the garbage bag from the conveyor, and then transfers the grabbed garbage bag with the translation mechanism.

[0022] One end of the guide rail frame 4 is equipped with a drive mechanism for moving the translation mechanism. The drive mechanism includes a translation motor 1 fixed in the middle of one end of the guide rail frame 4. A reducer 2 is installed on the motor shaft of the translation motor 1. A transmission shaft 17 extends horizontally from each end of the reducer 2. A set of transmission mechanisms is provided at the ends of the two transmission shafts 17. The transmission mechanisms extend along the guide rail frame 4 to the other end, and the transmission mechanisms on both sides are connected to the translation mechanism. A limit switch 15 is also provided at the end of each set of transmission mechanisms to limit the translation position of the translation mechanism.

[0023] The transmission mechanism is implemented using a synchronous belt mechanism, including synchronous pulleys 16 located at the four corners of the guide rail frame 4. Two synchronous pulleys 16 located on one side of each transmission shaft 17 are connected by a synchronous belt 3, and the synchronous belts 3 on both sides are connected to the translation mechanism. The transmission mechanism can also be implemented using other structures known in the art, such as chain and sprocket mechanisms and pulley mechanisms.

[0024] The translation mechanism includes a translation carriage 7, with its two ends positioned directly above two guide rails 5 along its length. A set of rollers is provided at each end of the translation frame near the guide rails 5, enabling a sliding connection between the translation carriage 7 and the two guide rails 5. Each set of rollers includes a top translation guide wheel 9 located on the upper part of the translation carriage 7 and in contact with the upper surface of the guide rail 5, a bottom translation guide wheel 8 located on the lower part of the translation carriage 7 and in contact with the lower surface of the guide rail 5, and a side translation guide wheel 22 located at the end of the translation carriage 7 and in contact with the side of the guide rail 5.

[0025] The two synchronous belts 3 are fixed to both ends of the translation vehicle 7. When the translation motor 1 rotates, it drives the two transmission shafts 17 to rotate through the reducer 2. When the two transmission shafts 17 rotate, they drive the transmission mechanism on the corresponding side to run. The synchronous belts 3 in the transmission mechanisms on both sides drive the translation vehicle 7 to move back and forth along the guide rail 5.

[0026] The translation mechanism also includes a gripping vehicle 6 slidably connected to the translation vehicle 7. The gripping vehicle 6 translates along the length of the translation vehicle 7 (perpendicular to the arrangement direction of the guide rail 5). A set of locking wheels is also provided on both sides of the gripping vehicle 6 for engaging with the translation vehicle 7. The locking wheels at the ends of the gripping vehicle 6 include a gripping guide top wheel 19 located at the upper part of the gripping vehicle 6 and in contact with the upper surface of the translation vehicle 7, and a gripping guide bottom wheel 21 located at the lower part of the gripping vehicle 6 and in contact with the lower surface of the translation vehicle 7. A translation cylinder 20 is also provided on the upper surface of the translation vehicle 7. The piston rod of the translation cylinder 20 is connected to the gripping vehicle 6. When the piston rod of the translation cylinder 20 reciprocates, it drives the gripping vehicle 6 to reciprocate across the surface of the translation vehicle 7.

[0027] The gripping mechanism includes an extension frame 14 vertically fixed to the bottom of the gripping vehicle 6, and a folding frame 18 hinged to the bottom of the extension frame 14. The gripping vehicle 6 and the folding frame 18 are connected by a swing cylinder 13. The cylinder body of the swing cylinder 13 is connected to the gripping vehicle 6, and the piston rod of the swing cylinder 13 extends downward to the folding frame 18 and is hinged to the folding frame 18. When the swing cylinder 13 is activated, it drives the folding frame 18 to swing around the bottom of the extension frame 14.

[0028] A mounting plate 12 is fixed at the end of the folding frame 18. A gripping cylinder 11 is installed at each end of the mounting plate 12. The gripping cylinder 11 is implemented using a gripper cylinder commonly used in the art. A clamping plate 10 is installed on the upper gripper of the gripping cylinder 11 at both ends, and another clamping plate 10 is installed on the lower gripper of the gripping cylinder 11 at both ends. The two clamping plates 10 are arranged opposite each other.

[0029] The specific working process and working principle are as follows:

[0030] The garbage is conveyed along with the garbage bags on the conveyor surface. First, the bag-breaking mechanism in the garbage sorting system breaks the bags, at which point the garbage bags and the garbage inside are conveyed independently on the conveyor belt surface. The garbage sorting system then sorts the garbage. The sorting principle of the garbage sorting system, the specific structure of the bag-breaking mechanism, and the sorting of different types of garbage are all common knowledge in the field (such as the technical solution described in Chinese invention patent application number 202010924333.9, application date September 4, 2020, entitled "A Fully Automatic Garbage Sorting and Recycling Equipment"), and will not be elaborated here.

[0031] When it is necessary to clamp the garbage bags on the surface of the conveyor, the translation motor 1 works, and drives the translation car 7 to move towards the conveyor through the reducer 2 and the transmission mechanism on both sides. At the same time, the gripping cylinder 11 moves to open the upper and lower clamping plates 10. Simultaneously, the piston rod of the translation cylinder 20 outputs, pushing the translation car 7 away, and the piston rod of the swing cylinder 13 resets, so that the folding frame 18 (i.e., clamping plate 10) is in a horizontal state.

[0032] When the translation vehicle 7 moves to the conveyor, the piston rod of the swing cylinder 13 outputs, causing the folding frame 18 to swing downward, so that the clamping plate 10 contacts the garbage bag on the surface of the conveyor. Then the piston rod of the translation cylinder 20 returns to its original position, so that the clamping plate 10 moves relative to the garbage on the surface of the conveyor in an inclined state, so that the garbage bag enters between the two clamping plates 10.

[0033] The gripping cylinder 11 closes, clamping the garbage bag through the clamping plate 10. Then the piston rod of the swing cylinder 13 resets, bringing the folding frame 18 back to a horizontal position and pulling the garbage bag out of the garbage. The piston rod of the translation cylinder 20 outputs again, or after outputting, a reset-output cycle is performed again, causing the garbage remaining on the surface of the garbage bag to fall onto the surface of the conveyor.

[0034] Then, the translation motor 1 drives the translation vehicle 7 away from the conveyor. A collection box can be set on the side of the conveyor. When it moves to the top of the collection box, it stops. The swing cylinder 13 is activated, controlling the folding frame 18 to swing downwards and toward the collection box below it. Finally, the grab cylinder 11 is activated again, causing the two clamping plates 10 to separate and the garbage bag to fall into the collection box. This process is repeated.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
