Abstract

The present invention provides a garbage compression and packing device and method, comprising a square box-shaped compression box, the rear end of which is equipped with a pushing mechanism for squeezing garbage into shape. A garbage feed inlet is located above the rear end of the compression box, and the front end serves as a garbage compression and forming station. A gate is provided at the front end of the compression box, and a garbage block packing station is located outside the gate. The device also includes a transfer mechanism for transferring garbage cans from a storage station to a packing station, and a proximity switch for detecting the presence of a garbage can at a storage station. This solution adds a signal indicating the presence of a garbage can at a storage station, allowing for logical determination of the fullness of the garbage can at that location. This simple structure does not significantly alter the existing structure of the garbage compression device, making it convenient for retrofitting existing garbage compression stations.

Description

Technical Field

[0001] The present invention relates to the field of garbage collection and processing, and in particular to a garbage compression and packing device and method. Background Art

[0002] After the garbage is recycled to the garbage station, it generally needs to be compressed into blocks and then placed in a trash can. A trash can can generally hold 2-4 pieces of garbage, making it easier to landfill, incinerate, and other processes.

[0003] The prior art garbage compression and packing device includes a square box-shaped compression box with a pushing mechanism at the rear end. A garbage feed port is located above the rear end of the compression box, and the front end of the compression box serves as a garbage compression and forming station. A gate is located at the front end of the compression box, and a garbage block packing station is located outside the gate. The garbage compression method involves a box-moving mechanism transferring a garbage can from a storage station to a packing station. Garbage is fed into the compression box, and the pushing mechanism advances to compress the garbage into blocks. The gate opens, and the pushing mechanism continues to push the garbage blocks into the garbage can. After multiple compressions and pushes, the box-moving mechanism transfers the garbage can from the packing station to a storage station, where a hook truck, forklift, or crane removes the garbage can and places an empty one. However, since it is impossible to determine whether a garbage can at the storage station is empty, if a full garbage can is not removed in time, the box-moving mechanism moves the garbage can to the packing station, where the pushing mechanism crushes the garbage blocks. At the same time, the length of the garbage blocks is difficult to control. When multiple garbage blocks are piled in a garbage bin, it is easy for the total length of the garbage blocks to exceed the length of the garbage bin, which will also burst the garbage bin. Summary of the Invention

[0004] The purpose of the present invention is to provide a garbage compression and packing device and method to avoid the explosion of garbage bins.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a garbage compression and packing device, including a square box-shaped compression box, a rear end of the compression box is provided with a pushing mechanism for squeezing garbage into shape, a garbage feeding port is provided above the rear section of the compression box, and the front section is a garbage compression and molding position, a gate is provided at the front end of the compression box, and the outer side of the gate is a garbage block packing station, and also includes a box moving mechanism for transferring the garbage can from the box placing station to the box packing station, including a proximity switch for detecting whether there is a garbage can on the box placing station.

[0006] In the above scheme, by adding a set of signals to indicate whether there is a trash can at the box placement station, it is logically determined whether the trash can at that location is full. The structure is simple and no major changes are made to the existing garbage compression device structure, which facilitates the transformation of the existing garbage compression station.

[0007] To achieve the above-mentioned purpose, the present invention also adopts the following method: a garbage compression and packing method, A. Place an empty garbage can on the box rack located at the box placement station, and the proximity switch collects the garbage can signal and marks it as X1 (empty); B. The box transfer mechanism transfers the garbage can to the packing station, and the proximity switch loses the garbage can signal; C. The box transfer mechanism transfers the garbage can to the packing station and loads the garbage blocks into the garbage can; D. The box transfer mechanism transfers the garbage can from the packing station to the box placement station, and the proximity switch collects the garbage can signal, determines that the garbage can has not been replaced and marks it as X1 (full); E. Replace the garbage can on the box placement station, and the proximity switch collects the garbage can signal again after losing the garbage can signal, and the box transfer mechanism does not move, determines that the garbage can has been replaced, and marks it as X2 (empty); F. Repeat steps BE.

[0008] In the above scheme, whether the trash can at the placement station is full can be determined through logical judgment, rather than directly detecting whether the trash can is full. Through logical connections at the program level, it avoids the need to arrange more complex detection mechanisms at the mechanical level to detect the trash can. The cost is low and it is convenient for batch modification. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0010] A garbage compression and packing device includes a square box-shaped compression box 10, a rear end of the compression box 10 is provided with a pushing mechanism 20 for squeezing garbage into shape, a garbage feeding port 11 is provided above the rear section of the compression box 10, and the front section is a garbage compression and molding position, a gate plate 12 is provided at the front end of the compression box 10, and the outer side of the gate plate 12 is a garbage block packing station 30, and also includes a box moving mechanism 50 for transferring the garbage can 1 from the box placing station 40 to the packing station 30, including a proximity switch 60 for detecting whether there is a garbage can 1 on the box placing station 40.

[0011] The proximity switch 60 in the above solution can be any other sensor that can detect whether there is a trash can 1 on the box placement station 40, such as a photoelectric signal sensor, a pressure sensor, etc. In the above solution, a pressure sensor can also be directly set on the box placement station 40 or the box transfer mechanism 50 to detect the weight of the trash can 1 to determine whether it is an empty trash can. The disadvantage of this solution is that the box placement station 40 and the box transfer mechanism 50 are both existing components, and it is cumbersome and complicated to arrange the pressure sensor under them, involving the disassembly and modification of existing components. Therefore, the preferred solution of the present application is to set the proximity switch 60 next to the box placement station 40, and by adding a set of signals to indicate whether there is a trash can on the box placement station, it is logically determined whether the trash can at that location is full. The structure is simple, and no major changes are made to the existing garbage compression device structure, which facilitates the modification of existing garbage compression stations.

[0012] The pushing mechanism 20 is provided with a displacement sensor. The displacement sensor determines the pushing distance of the pushing mechanism 20 to avoid pushing too much and crushing the trash can 1.

[0013] The bin transfer mechanism 50 includes a track 51 whose length is perpendicular to the pushing direction of the pushing mechanism 20. A bin placement rack 52 is provided on the track 51 for transferring the trash can 1. When the trash can 1 on the bin placement rack 52 is positioned in the pushing direction of the pushing mechanism 20, it serves as the packing station 30. When the trash can 1 on the bin placement rack 52 is positioned away from the pushing direction of the pushing mechanism 20, it serves as the unpacking station 40. The position switching of the trash can 1 is achieved by translating the track, resulting in a simple structure, a close distance between the two stations, and rapid switching.

[0014] The box placing station 40 is provided at least on each of the left and right sides of the box packing station 30. In this way, when the box moving mechanism 50 transfers the trash can 1 from the box packing station 30 to the box placing station 40, the trash can 1 on the box placing station 40 on the other side can be quickly transferred to the box packing station 30, thereby improving the box packing efficiency.

[0015] A method for compressing and packing garbage includes the following steps: A. placing an empty garbage can 1 on a bin placement rack 52 located at a bin placement station 40, and a proximity switch 60 collects a signal from the garbage can 1 and marks it as X1 (empty); B. a bin transfer mechanism 50 transfers the garbage can 1 to a packing station 30, and the proximity switch 60 loses the signal from the garbage can 1; C. the bin transfer mechanism 50 transfers the garbage can 1 to the packing station 30, and packs garbage blocks into the garbage can 1; D. the bin transfer mechanism 50 transfers the garbage can 1 from the packing station 30 to the bin placement station 40, and the proximity switch 60 collects a signal from the garbage can 1, determines that the garbage can 1 has not been replaced, and marks it as X1 (full); E. replacing the garbage can 1 on the bin placement station 40, and the proximity switch 60 collects a signal from the garbage can 1 again after losing the signal from the garbage can 1, and the bin transfer mechanism 50 does not move, determines that the garbage can 1 has been replaced, and marks it as X2 (empty); F. repeating steps B to E.

[0016] In the above scheme, the judgment logic of the proximity switch 60 is as follows: if the bin moving mechanism 50 has not moved and receives a signal from trash can 1, it determines that trash can 1 has been replaced and marks it as empty. After the bin moving mechanism 50 moves and receives a signal from trash can 1, it determines that trash can 1 has not been replaced and marks it as full. Trash can 1 marked as full will not be moved to the bin placement station 40. In the above scheme, the displacement signal of the bin moving mechanism 50 is linked to the proximity switch 60 to determine whether trash can 1 has been replaced and whether it is empty. Alternatively, the status of trash can 1 can be determined using only the signal from the proximity switch 60. The logic is as follows: after receiving a signal from trash can 1 for an odd number of times, it is determined that trash can 1 has been replaced and marked as empty. After receiving a signal from trash can 1 for an even number of times, it is determined that trash can 1 has not been replaced and is marked as full. This logic can still determine the status of the trash can 1. However, if the empty trash can 1 is replaced with an empty one at the placement station 40 due to damage to the trash can 1 or other factors, the detection sequence of the proximity switch 60 will be disrupted, requiring readjustment. Therefore, the preferred solution is to link the displacement signal of the trash can transfer mechanism 50 with the proximity switch 60 for determination. This logical connection at the program level avoids the need for a more complex detection mechanism at the mechanical level to detect the trash cans, which is low-cost and easy to implement in batches.

[0017] Compressing the garbage and loading it into the trash can 1 on the packing station 30 includes the following steps: a. Putting the garbage into the feed port 11; b. The pushing mechanism 20 repeatedly pushes the garbage below the feed port 11 to the front section of the compression box 10. When the feedback pressure of the pressure sensor on the pushing mechanism 20 reaches the set value, the garbage is compressed into a block. The displacement sensor on the pushing mechanism 20 records the distance between its front end and the gate 12 as L1, which is the length of the garbage block. c. Opening the gate 12, the pushing mechanism 20 pushes the garbage block to the bottom of the trash can 1 and records the length of the garbage in the trash can 1; d. The pushing mechanism 20 retracts and closes the gate 12, repeating step b to obtain a garbage block of length Ln; e. Determine whether L1+L2+…+Ln is less than the maximum total length design value of the garbage block in the trash can 1. If so, return to step c. If not, replace the trash can 1 and retain the value of Ln, change its mark to L1, and return to step a. In the above scheme, each time a garbage block is loaded, its length or number is counted, and it is determined whether the design value of the garbage bin capacity will be exceeded after further loading of garbage blocks, so as to avoid crushing the garbage bin 1, wherein the number of garbage blocks in the garbage bin 1 is n-1, and the loading distance pushed forward by the pushing mechanism 20 is the distance between the bottom of the garbage bin 1 and the gate 12 minus the total length of the garbage blocks in the garbage bin 1.

[0018] In step D, after the bin transfer mechanism 50 transfers the trash can 1 from the packing station 30 to the placing station 40, the bin transfer mechanism 50 transfers the trash can 1 on the placing station 40 on the other side of the packing station 30 to the packing station 30 for garbage block packing. In this way, during the interval between bin changes at the placing station 40 on one side, the trash can 1 on the placing station 40 on the other side can be transferred to the packing station 30, thereby improving packing efficiency and saving time.

[0019] When the Xn (full) mark is obtained, a signal is sent to notify the bin-changing personnel or device, which is helpful for the bin-changing personnel or device to replace the full trash bin 1 in time, thereby improving work efficiency.
