Description

TECHNICAL FIELD

[0001] The present application relates to a transfer box automatic handling device, method and garbage collection station, belonging to the technical field of household garbage transfer mechanical equipment. BACKGROUND

[0002] In large and medium-sized cities, due to factors such as land shortage and high construction cost, garbage collection stations often cannot be built into large-span, multi-station large-scale transfer stations, and are usually only small garbage buildings with two or three spans; Such garbage collection stations have limited internal space and usually only one fixed garbage compactor is configured. Under this structure, garbage collection and transfer need to be achieved by frequent switching between empty transfer boxes and full transfer boxes to complete the compression operation and the rear-end transfer.

[0003] In related technologies, the switching between empty and full boxes is mainly completed by the rear-end garbage truck. In actual use scenarios, the rear-end garbage truck is often selected to be a hook arm truck. After returning from the rear-end processing plant, the hook arm truck needs to place an empty box at a non-compression station and then hook a full box at a compression station, or first move the full box out and then transfer the empty box. During the entire process, the hook arm truck needs to repeatedly perform hooking and placing operations, which not only occupies a long time, but also causes low vehicle utilization, resulting in insufficient compression and transfer efficiency in the station.

[0004] In order to improve efficiency, some related technologies propose to set a box moving device to enable the transfer box to move laterally between two stations. However, the existing two-box two-station box moving technology mostly relies on a box moving trolley to supplement a complete box placing track. The hook arm truck needs to wait for the track to be completed before performing the box hooking and placing operations. This way causes the box moving trolley to have multiple empty trips in one operation cycle, resulting in low energy consumption and equipment utilization. At the same time, the hook arm truck also needs to wait for the track to be completed before operation, which still has an efficiency bottleneck. SUMMARY

[0005] The present application aims to overcome the deficiencies in the related art. The existing small garbage collection station is limited in space, and only relies on the hook arm truck to switch between empty and full boxes, resulting in the problems of complicated operation and low efficiency.

DETAILED DESCRIPTION

[0018] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments and specific features in the embodiments of the present application are detailed descriptions of the technical solutions of the present application, and not limitations of the technical solutions of the present application. In the case of no conflict, the technical features in the embodiments and the embodiments can be combined with each other.

[0019] The term "and / or" in this paper is only a description of the association relationship between the associated objects, which means that there can be three kinds of relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are in an "or" relationship.

[0020] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the embodiments and the features in the embodiments described below can be combined with each other.

[0021] The present embodiment at least provides a garbage collection station, as shown in Figure 9 and Figure 10 As shown, it includes a transfer box 1, a compression station 2 and a non-compression station 3; a transfer box automatic handling device, a garbage compressor 4 arranged at the compression station 2, a front-end garbage truck 5 for garbage collection and a rear-end garbage truck 6 for transfer of the transfer box 1; the rear-end garbage truck 6 is a hook arm truck in this embodiment.

[0022] Specifically, a pit is dug in the station house of the garbage collection station, as shown in Figure 3The pit in the form of a center line frame is used to place the box transfer trolley 7 and the box placement track 8.

[0023] like Figure 1 and Figure 2 As shown in the figure, the box transfer trolley 7 is schematically shown. The box transfer trolley 7 is only set with two extreme positions: the non-compression station 3 transfer box 1 placement position and the compression station 2 transfer box 1 placement position. The box transfer trolley 7 does not stop at the middle position.

[0024] like Figure 3 As shown in the figure, the fixed box release track 8 of the compression station 2 and the non-compression station 3 is shown. The box release track 8 plays a guiding role and is used for the hook arm vehicle to accurately hook and release the box.

[0025] like Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the box-transferring trolley 7 is provided with a lifting mechanism 72 and a locking mechanism 71. When the lifting mechanism 72 is not raised, the upper surface of the trolley is lower than the longitudinal beam position at the bottom of the box body. The box-transferring trolley 7 (in the non-lifted state) can pass through the bottom of the box body without interfering with the box body.

[0026] When the transfer box 1 needs to be transferred between the non-compression station 3 and the compression station 2, the lifting mechanism 72 of the box transfer trolley 7 is raised. After the lifting mechanism 72 contacts the bottom beam of the box body, the locking mechanism 71 is activated to lock the box body; after locking, the lifting mechanism 72 continues to rise, so that the box body roller 74 is free from the restriction of the limit plate 821 of the fixed box release track 8.

[0027] After the box transfer trolley 7 leaves a workstation, it cannot leave a "pit" at the workstation. Specifically, the box placement track 8 of the workstation left must be restored to its original state as soon as possible so that the next box placement can be carried out, so as not to affect the longitudinal box hooking and unloading functions of the hook arm car at the workstation. The hook arm car needs to maintain the integrity of the box placement track 8 when hooking and unloading the box.

[0028] like Figure 11 As shown, for the automatic handling device of transfer boxes, this solution sets up a retractable track in the form of a synchronous belt electric push rod; a box placing track 8 is provided, and the box placing track 8 includes a retractable part 81, and the retractable part 81 includes: a motor 811, a driving pulley 812 connected to the output end of the motor 811, a driven pulley 813 connected to the driving pulley 812 through a synchronous belt, a screw 814, a retractable block 815 and a guide block 816; the screw 814 is coaxially connected to the driven pulley 813, and pushes the retractable block 815 under the action of the guide block 816.

[0029] In some embodiments, the automatic transfer box handling device can be used in a two-box, two-station transfer scenario.

[0030] Specifically, when the box moving trolley 7 needs to leave the station, the telescopic platform is retracted on both sides along the trolley center to avoid the trolley driving space; after the trolley drives through the track position, the telescopic platform is extended again to serve as a track function, which does not affect the hooking and unloading of the transfer box 1 at the station.

[0031] The automatic transfer box handling device further comprises a locking mechanism 71, a lifting mechanism 72 and a chassis 73; the bottom end of the chassis 73 is provided with a roller 74 through a bearing seat 732, the box moving trolley 7 moves between the compression station 2 and the non-compression station 3 through the roller 74; the lifting mechanism 72 is used to separate the transfer box 1 from the box placing track 8 or place the transfer box 1 on the box placing track 8; the locking mechanism 71 is used to lock with the transfer box 1.

[0032] The box placing track 8 comprises a telescopic part 81 and a fixed part 82; the fixed part 82 is arranged at the compression station 2 and the non-compression station 3 respectively, the telescopic part 81 is connected with the fixed part 82, and the telescopic part 81 and the fixed part 82 form a complete box placing track 8 for placing the transfer box 1 after the telescopic part 81 is completely telescoped.

[0033] The telescopic part 81 forms a track for the box moving trolley 7 to move between the compression station 2 and the non-compression station 3 after being completely retracted.

[0034] The bottom end of the chassis 73 is provided with a roller 74 through a bearing seat 732, the box moving trolley 7 moves between the compression station 2 and the non-compression station 3 through the roller 74; the lifting mechanism 72 is used to separate the transfer box 1 from the box placing track 8 or place the transfer box 1 on the box placing track 8; the locking mechanism 71 is used to lock with the transfer box 1.

[0035] The box placing track 8 comprises a telescopic part 81 and a fixed part 82; the fixed part 82 is arranged at the compression station 2 and the non-compression station 3 respectively, the telescopic part 81 is connected with the fixed part 82, and the telescopic part 81 and the fixed part 82 form a complete box placing track 8 for placing the transfer box 1 after the telescopic part 81 is completely telescoped.

[0036] The telescopic part 81 forms a track for the box moving trolley 7 to move between the compression station 2 and the non-compression station 3 after being completely retracted.

[0037] The locking mechanism 71 comprises a support seat 711, a bidirectional oil cylinder 712, a guide 713 and a locking hook 714; the bidirectional oil cylinder 712 is installed on the support seat 711, the bidirectional oil cylinder 712 comprises two extension ends, the two extension ends are respectively provided with the guide 713, and the locking hook 714 is connected with the guide 713.

[0038] The lifting mechanism 72 comprises a guide plate 721 and a jacking piece 722; the jacking pieces 722 are oppositely arranged and the guide plate 721 is arranged in the middle.

[0039] The chassis 73 further comprises a transmission assembly 731, a bearing seat 732 and a connecting rod 733; the connecting rod 733 connects two rollers 74 coaxially; the bearing seat 732 and the connecting rod 733 are used for limiting the rollers 74 and cooperating with the transmission assembly 731 to drive the rollers 74 to roll.

[0040] The transmission assembly 731 comprises a speed reducer 7311, a driving sprocket 7312 and a driven sprocket 7313; the output end of the speed reducer 7311 is engaged with the driven sprocket 7313 through the driving sprocket 7312, and the driven sprocket 7313 is installed on the connecting rod 733.

[0041] As shown in Figure 12 The fixing part 82 further comprises a limiting plate 821; the limiting plate 821 cooperates with the rollers 74 and limits the rollers 74.

[0042] Specifically, first, it is confirmed that the box moving trolley 7 is at a station with a transfer box 1; the adjacent station without the box moving trolley 7 has no transfer box 1.

[0043] In one specific embodiment, for transferring an empty box from a non-compression station 3 to a compression station 2.

[0044] It should be noted that when the box moving trolley 7 starts to act, the telescopic parts 81 of the two stations are retracted to provide space for the box moving trolley 7 to run; after the box moving trolley 7 passes the original station, the telescopic part 81 of the original station is restored, so that the original station can be placed with an empty box by the hook arm vehicle; the hook arm vehicle is the rear-end garbage truck 6, and the hook arm vehicles described later are all rear-end garbage trucks 6.

[0045] After the box moving trolley 7 completely enters the adjacent station, the telescopic part 81 of the adjacent station is not restored temporarily, because the box moving trolley 7 needs to return empty and wait for the next cycle.

[0046] As shown in Figure 13 The working process is as follows: The lifting mechanism is raised to contact the bottom girder of the box body, which comprises: the lifting mechanism 72 of the box moving trolley 7 is raised, and when the locking mechanism 71 contacts the bottom longitudinal beam of the box body: The process of completing the butt joint, locking and fixing of the box body prevents the box body from shaking during the transverse movement of the box moving trolley 7, which may cause safety hazards; The locking mechanism locks the bottom beam of the box body, including: then the piston rod of the locking mechanism 71 (a bidirectional moving cylinder) is retracted to lock the bottom beam of the box body; in a specific embodiment, an alternative solution to the above-mentioned locking mechanism 71 is: a pin is set on the top of the electric screw lifting mechanism (the screw lifting mechanism can be replaced by a cylinder), and the pin is directly inserted into the pin hole reserved at the bottom of the box body to achieve the function of locking and positioning the box body.

[0047] The lifting mechanism continues to lift until the box rollers are free from the limit plate of the box release track, including: after the box is locked, the lifting mechanism 72 lifts again to lift the box rollers 74 to be free from the limit plate 821 of the box release track 8; The retractable track mechanisms of the two box-releasing tracks are retracted to leave a clearance space, which includes: the retractable parts 81 of the two box-releasing tracks 8 (located in the middle of the box-releasing tracks 8) are retracted to leave a clearance space for the box-transferring trolley 7 to move laterally; The box transfer trolley moves laterally across the non-compression station box placement track, including: the box transfer trolley 7 uses its own power source (motor drive) to carry the box body and move laterally to the adjacent station; The retractable track of the non-compression station is extended to complete the track, which includes: when the box transfer trolley 7 completely passes over the non-compression station 3, the box placement track 8 of the non-compression station 3 is extended to complete the box placement track 8 of the non-compression station 3, and the next empty box can be placed on the station by the hook arm vehicle; The box transfer trolley completely reaches the compression station, the lifting mechanism descends, and the box roller contacts the compression station box release track. This includes: after the box transfer trolley 7 moves to the compression station 2, the lifting mechanism 72 descends, first causing the box roller 74 to contact the upper surface of the compression station 2 box release track 8, and the roller 74 is limited by the station limit plate 821; The locking mechanism releases the bottom beam of the box body, which includes: at this time, the piston rod of the locking mechanism 71 (the bidirectionally moving oil cylinder) extends and separates from the bottom beam of the box body.

[0048] The lifting mechanism continues to descend to the initial height state, which includes: the lifting mechanism 72 continues to descend and returns to the initial height state (at the initial height state, the box-moving trolley 7 does not interfere with the box body when moving horizontally), and the box body transportation is completed.

[0049] In a specific embodiment, the full box is transported from the compression station 2 to the non-compression station 3.

[0050] like Figure 14 As shown, the workflow is: The lifting mechanism is raised to contact the bottom beam of the box body, which includes: the lifting mechanism 72 of the box-moving trolley 7 is raised, and when the locking mechanism 71 contacts the longitudinal beam at the bottom of the box body: the docking, locking and fixing with the box body are completed in the following manner to prevent the box body from shaking during the horizontal movement of the box-moving trolley 7, which may cause safety hazards: The locking mechanism retracts the bottom beam of the box, including: the locking mechanism 71 (two-way moving oil cylinder) piston rod retracts, and the bottom beam of the box is locked. This step also provides an alternative solution: the top of the electric screw rod lifting mechanism is provided with a latch (the screw rod lifting mechanism can be replaced by an oil cylinder), which directly inserts the latch into the reserved latch hole in the bottom of the box to realize the functions of locking and positioning the box.

[0051] The lifting mechanism continues to rise to the point where the box roller is lifted off the limiting plate of the box placing track, including: after the box is locked, the lifting mechanism 72 lifts again to lift the box roller 74 off the limiting plate 821 of the box placing track 8; The retractable track mechanisms of the two box placing tracks are retracted to leave a space for the box moving trolley, including: the retractable track mechanisms of the two box placing tracks 8 (in the middle of the box placing track 8) are retracted to leave a space for the box moving trolley 7 to move laterally; The box moving trolley moves laterally over the compression station box placing track, including: the box moving trolley 7 moves laterally over the adjacent station under its own power source (motor drive) carrying the box; The compression station retractable track is extended to complete the track, including: when the box moving trolley 7 completely moves over the compression station 2, the box placing track 8 of the compression station 2 is extended to complete the box placing track 8 of the compression station 2, at which time the station can continue to place the next empty box by the hook arm vehicle; The box moving trolley completely reaches the non-compression station, including: after the box moving trolley 7 moves to the non-compression station 3, the lifting mechanism 72 is lowered, first making the box roller 74 contact the upper surface of the box placing track 8 of the non-compression station 3, and the roller 74 is limited by the limiting plate 821 of the station; The locking mechanism releases the bottom beam of the box, including: at this time, the locking mechanism 71 (two-way moving oil cylinder) piston rod is extended to separate from the bottom beam of the box.

[0052] The lifting mechanism is lowered, and the box roller contacts the box placing track of the non-compression station, including: the lifting mechanism 72 continues to be lowered to return to the initial height state (in the initial height state, the box moving trolley 7 does not interfere with the box during lateral movement), and the box handling is completed.

[0053] In one embodiment, a two-box two-station transfer box 1 automatic handling method is provided; Specifically, under the condition of no traffic command system, the empty box is moved from the non-compression station 3 to the compression station 2; The initial state is: The box moving trolley 7 is in the non-compression station 3; The non-compression station 3 has no box; The compression station 2 has a box and is compressing garbage.

[0054] It should be noted that the function of the box moving trolley 7 is only to carry the empty box from the non-compression station 3 to the compression station 2; the function of the hook arm vehicle is only to put down the empty box at the non-compression station 3, hook up the full box at the compression station 2, and then continue to transport to the back-end processing plant. When the box is placed in front of the garbage compressor 4, the push-pull mechanism pulls the box close, the claw mechanism holds the box tightly, and the docking is completed. Thereafter, the garbage can be compressed into the box; after the garbage is compressed into the full box, the claw mechanism on the garbage compressor 4 releases the box, and the push-pull mechanism pushes the box away, and the box separation is completed. Thereafter, the full box can be hooked by the hook arm vehicle and transported to the back-end processing plant.

[0055] Under this condition, as shown in Figure 15 , the working process is: The hook arm vehicle places the empty box on the box placing track 8 of the non-compression station 3; The hook arm vehicle hooks up the full box at the compression station 2 and transports it to the back-end processing plant; The box moving trolley 7 carries the empty box to the compression station 2; The box moving trolley 7 returns to the non-compression station 3 empty and waits for the next hook arm vehicle to place the empty box.

[0056] Specifically, without a traffic command system, the full box is carried from the compression station 2 to the non-compression station 3; The initial state is: The box moving trolley 7 is at the compression station 2; There is no box at the non-compression station 3; There is a box at the compression station 2, and the garbage is being compressed.

[0057] It should be noted that the function of the box moving trolley 7 is only to carry the full box from the compression station 2 to the non-compression station 3; the function of the hook arm vehicle is only to put down the empty box at the compression station 2, hook up the full box at the non-compression station 3, and then continue to transport to the back-end processing plant.

[0058] Under this condition, as shown in Figure 16 , the working process is: After the box at the compression station 2 is compressed full, the box moving trolley 7 carries the full box to the non-compression station 3; The hook arm vehicle places the empty box on the box placing track 8 of the compression station 2; The hook arm vehicle hooks up the full box at the non-compression station 3 and transports it to the back-end processing plant; The box moving trolley 7 returns to the compression station 2 empty and waits for the next time the garbage box is full.

[0059] Specifically, with a traffic command system, the current carrying operation is comprehensively judged to maximize the transfer efficiency; The initial state is: The box moving trolley 7 is at the non-compression station 3; There is no box at non-compression station 3 (the traffic light at non-compression station 3 is green); There is a box at compression station 2 and the garbage is being compressed (the traffic light at compression station 2 is yellow).

[0060] It should be noted that: Prioritize the transfer of empty boxes from non-compression station 3 to compression station 2; When the box at the compression station 2 is full, but the hook arm truck carrying the empty box has not returned to the garbage collection station, the box transfer trolley 7 first moves the full box from the compression station 2 to the non-compression station 3.

[0061] Traffic control system principles: Red, green and yellow lights, a total of three colors, representing: A red light means that the workstation has full boxes that can be taken away by hook; A yellow light indicates that the retractable track mechanism of the workstation has not been fully reset, there is an empty box or the box is not full of garbage, and the hooking and releasing of boxes are not allowed at this time; The green light means that there is no box at the workstation and the retractable track mechanism has been fully reset, and the empty box can be placed.

[0062] Traffic lights for compression station 2 and non-compression station 3, as well as the status of the station and the operations that the hook arm truck can perform; As shown in Table 1:

[0063] Specifically, if Figure 17 As shown, T1: represents condition 1, i.e. "whether the box of compression station 2 is full" T1=1, indicating that the box of compression station 2 is full; T1=0, indicating that the box of compression station 2 is not full; T2: represents condition 2, i.e., whether there is a hook truck carrying empty containers returning to the station from the back-end processing plant. T2=1, indicating that a hook truck carrying an empty container returns to the station from the back-end processing plant; T2=0 means that no hook truck carries empty containers back to the station from the back-end processing plant; D1: represents action 1; D2: represents action 2; For compression station 2: The processes of "placing empty boxes (or transferring empty boxes by box transfer trolley 7)" and "chassis docking" are closely connected; The processes of "chassis being filled" and "chassis separation" are closely followed; Therefore, the description of the "chassis docking" and "chassis separation" processes is omitted in the process flow logic block diagram.

[0064] For the work flow, the system state is monitored in real time by sensors, and a comprehensive judgment is made in combination with the current "whether the box in the compression station 2 is full" and "whether the hook arm vehicle carries an empty box from the rear end processing plant back to the station". When the time when the hook arm vehicle carries an empty box from the rear end processing plant back is earlier than or equal to the time when the box in the compression station 2 is full: The hook arm vehicle places the empty box in the non-compression station 3, the hook arm vehicle hooks the full box in the compression station 2 to the rear end processing plant, the box moving trolley 7 carries the empty box to the compression station 2, and the box moving trolley 7 returns to the non-compression station 3, and the system returns to the initial state.

[0065] When the time when the hook arm vehicle carries an empty box from the rear end processing plant back to the station is later than the time when the box in the compression station 2 is full: The box moving trolley 7 moves to the compression station 2, the box moving trolley 7 carries the full box to the non-compression station 3, the hook arm vehicle carrying the empty box returns to the station, and the empty box is unloaded to the compression station 2, the hook arm vehicle hooks the full box in the non-compression station 3 to the rear end processing plant, and the system returns to the initial state.

[0066] In one specific embodiment, an alternative of the box placing track 8 of the present embodiment is: A foundation pit is dug below the elevation of the box moving trolley 7 to set a lifting platform; When the hook arm vehicle is needed to hook and unload the box, the lifting platform is raised to serve as the box placing track 8; When the box moving trolley 7 is needed to move the box between the non-compression station 3 and the compression station 2, the lifting platform is lowered to give the box moving trolley 7 a driving space.

[0067] For the locking form of the box moving trolley 7 and the box: A latch is arranged at the top of the electric screw rod lifting mechanism (the screw rod lifting mechanism can also be replaced by an oil cylinder), and the latch is directly inserted into the latch hole reserved at the bottom of the box to realize the function of locking and positioning the box; The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, a number of improvements and modifications can be made without departing from the technical principles of the present application, and these improvements and modifications should also be considered as the protection scope of the present application.
