Description

TECHNICAL FIELD

[0001] The present application mainly relates to the technical field of medical waste treatment, in particular to a medical turnover box turnover machine and a cleaning line. BACKGROUND

[0002] Turnover boxes are important tools in the field of medical waste treatment. Turnover boxes are used in medical waste treatment every day and need to be cleaned and stacked after use. Before entering the cleaning machine, the turnover box is turned over by 90°, so that its opening faces the side, facilitating cleaning and disinfection in the cleaning machine.

[0003] In the prior art, the turnover structure for the turnover box, such as the prior art with the announcement number CN201313751Y and the name of medical waste turnover box turnover mechanism, mainly includes a support frame, a hydraulic cylinder, a rotating seat and a turnover box fixing frame. The rotating seat is fixed to the upper end of the support frame and is in rotating connection with the turnover box fixing frame. The hydraulic cylinder is connected with the support frame and the turnover box fixing frame. When the hydraulic rod of the hydraulic cylinder is extended or retracted, the turnover box fixing frame rotates around the rotating seat to realize the turnover and reset of the turnover box. Through the extension and retraction of the hydraulic rod, the turnover and reset actions of the turnover box can be realized. The publication number is CN113548374A, and the name is a steel turnover box automatic cleaning system of a turnover type vacuum conditioning machine. The mechanism for completing the turnover action mainly includes a clamping mechanism arranged on the other side of the conveying belt for clamping the turnover box, and a turnover mechanism including a turnover frame and a turnover motor. The turnover frame is connected with the clamping mechanism, and the turnover motor drives the turnover frame to turn over the clamping mechanism and the turnover box clamped thereby to the other side of the turnover mechanism. The same point of the two is that the turnover box is clamped and fixed, and then a 90° turnover action is performed around a certain rotation axis. The structure is not compact, and it is not convenient to dock with the cleaning machine.

[0004] In the prior art, the stacking mechanism for the cleaned turnover box, such as the patent with the name of a turnover box stacking machine and its stacking method (CN202010236888.4), mainly realizes stacking by the cooperation of the lifting mechanism and the clamping mechanism. The clamping mechanism assembly completes clamping through the driving of the cylinder and the connecting rod. The stacking method is mainly as follows: the lifting mechanism lifts the turnover box upward — the clamping mechanism clamps — the lifting mechanism descends — the next turnover box is in place — the lifting mechanism lifts the turnover box upward to complete a stacking; that is, the stacking is performed in a top-down manner. The structure of the lifting and clamping mechanisms of the existing equipment is complex, and the lifting and clamping processes are separated, which cannot guarantee the stability of the turnover box during lifting.

[0048] Figures 1-5 ​​​​​​​​​​​The main structure of the turnover machine of the embodiment is shown as follows.

[0049] The turnover machine comprises a rack assembly 11, a plate chain conveying mechanism 15, a roller conveying mechanism 16, a turnover mechanism 12, a positioning mechanism 13, and a grabbing mechanism 14.

[0050] The plate chain conveying mechanism 15 is composed of two plate chain conveying tracks, side plates, driving shafts, driven shafts, support assemblies, spacing plates, plate chain driving and driven sprockets, reduction motors, sprockets, chains, and shaft sleeves. The plate chain conveying mechanism 15 is arranged at one end of the rack assembly 11 and conveys the turnover boxes through the reduction motors and the chain structure.

[0051] The roller conveying mechanism 16 is composed of seven double-sprocket conveying rollers, side plates, reduction motors, and chains. A horizontal push cylinder mounting assembly is installed below the roller conveying mechanism 16 and is fixed below the side plates on both sides of the roller conveying mechanism. The roller conveying mechanism 16 is driven by the reduction motors to rotate the chains and the rollers, thereby conveying the turnover boxes. The roller conveying mechanism 16 is located at the other end of the rack assembly 11 and is connected to the plate chain conveying mechanism 15.

[0052] The turnover mechanism 12 comprises a side turnover rack 18, which is located above the plate chain conveying mechanism 15 and is installed on the side plates on both sides of the plate chain conveying mechanism 15. The side turnover rack 18 is provided with a push cylinder 111, a lifting cylinder 19, a linear guide rail pair, a turnover box hook plate assembly, a pressure regulating filter, a vacuum generator, and an electromagnetic valve guide.

[0053] The push cylinder 111 is connected to a cylinder horizontal push plate 110 through a cylinder piston rod and is provided with a linear guide rod on each side to ensure the stability of the cylinder extension and the pushing of the turnover boxes onto the hook plate 17.

[0054] The lifting cylinder 19 is vertically installed on the side turnover rack 18 and is connected to the hook plate 17 through a cylinder joint. When the turnover boxes are pushed onto the hook plate 17, the lifting cylinder 19 is retracted to drive the hook plate 17 to lift upward and complete the turnover action of the turnover boxes.

[0055] The hook plate 17 is connected to the lifting cylinder 19 through a cylinder joint. The hook plate 17 is provided with a linear guide rail pair on one side to ensure the stability of the upward and downward movement of the hook plate 17. The hook plate 17 is provided with a hook claw 121 on the inner side to hook the bottom of the turnover boxes. A baffle 122 is extended below the hook plate 17 to prevent the hook plate 17 from being separated from the turnover boxes and to ensure that the turnover boxes can be turned over even if the inclination angle is insufficient. Figure 5

[0056] ​The positioning mechanism 13 comprises a horizontal pushing cylinder 119 and a horizontal pushing limiting assembly 120. The horizontal pushing cylinder mounting assembly is located below the roller conveying mechanism 16 and is mounted on the side plates on both sides. The horizontal pushing cylinder 119 is mounted and connected with the pushing plate assembly 118. The pushing plate assembly 118 is located above the roller conveying mechanism 16. When the horizontal pushing cylinder 119 moves, the pushing plate assembly 118 is driven to push the already turned over toter into the positioning position. The horizontal pushing limiting assembly 120 is located above the roller conveying mechanism 16 and limits the direction in which the toter is pushed by the horizontal pushing cylinder 119, so as to ensure that the toter is pushed to the set position.

[0057] The grabbing mechanism 14 comprises a grabbing frame 113 which is located above the roller conveying mechanism 16 and is mounted on the side plates on both sides of the roller conveying mechanism 16. The grabbing frame 113 is mounted with a vertical cylinder mounting assembly 115, an advancing cylinder 112, a horizontal pushing limiting assembly 120, a drag chain, an upper limiting assembly 116 and the like. The vertical cylinder mounting assembly 115 is mounted with the vertical cylinder 114.

[0058] The vertical cylinder mounting assembly 115 can move horizontally on the grabbing frame 113 through rollers, bearings, hole retainer rings and bolt connections. The vertical cylinder 114 is mounted in the vertical direction and is provided with linear guide rods on the left and right sides. The cylinder end is connected with the suction assembly 117. When the vertical cylinder 114 extends downward, the suction assembly 117 sucks the toter. When the vertical cylinder 114 retracts upward, the toter is lifted. In the horizontal direction, the advancing cylinder 112 is connected through a cylinder connecting piece. When the advancing cylinder 112 extends and retracts, the vertical cylinder mounting assembly 115 can move horizontally. When the suction disc of the suction assembly 117 sucks and lifts the toter, the advancing cylinder 112 extends to push the vertical cylinder mounting assembly 115 to the next station.

[0059] The upper limiting assembly 116 limits the vertical direction of the vertical cylinder mounting assembly 115 and is used for guiding the vertical cylinder mounting assembly 115. When the vertical cylinder 114 extends downward to suck the toter, an upward reaction force is generated. The upper limiting assembly 116 can limit the upward displacement of the vertical cylinder mounting assembly 115 to avoid damaging the advancing cylinder 112.

[0060] The design concept of the embodiment is novel, solves the problems of complex structure and large floor area of the prior art equipment, facilitates large-scale and high-efficiency work and uninterrupted continuous operation. The toter is hooked by the toter hook plate to produce inclination to achieve the turning action. The toter hook plate has a limiting function to prevent the toter from being incompletely turned over. The design is compact, reasonable, convenient and practical and improves the work efficiency. Embodiment 2

[0061] The embodiment provides a cleaning and processing line for medical toters. Referring to Figure 6As shown, the main structure includes a cleaning machine 3, a turnover machine 1 arranged at the front and rear of the cleaning machine 3. The turnover machine 1 at the front is used to turn the toter box by 90° before the toter box enters the cleaning machine 3, so that the opening of the toter box faces the side. The turnover machine 1 at the rear is used to turn the toter box by 90° after the toter box is cleaned, so that the opening of the toter box faces upward. The toter box at the rear is provided with a stacking machine 2, which is used for stacking the toter box. Figures 1-5 As shown in the diagram, the structure of the turnover machine 1 at the front of the cleaning machine 3. In the structure of the turnover machine 1 at the rear of the cleaning machine 3, the hook plate 17 is arranged on the other side, which is used to turn the toter box from the other side.

[0062] In this embodiment, the working principle of the turnover machine at the front is described.

[0063] When the toter box is conveyed from the previous station to the turnover machine station, the plate chain conveying mechanism 15 stops moving. The horizontally installed advancing cylinder 111 at one side of the plate chain conveying mechanism 15 extends to push the toter box to the position of the hook plate 17 at the other side of the conveying mechanism. At this time, the advancing cylinder 111 retracts, the vertically placed lifting cylinder 19 driving the hook plate 17 retracts upward, and the hook plate 17 hooks the bottom of the toter box upward to lift one side of the toter box, so that the whole toter box is turned over and dumped. At this time, the plate chain conveying mechanism 15 is restarted to convey the toter box turned over by 90° to the roller conveying mechanism 16. When the toter box reaches the corresponding station, the roller conveying mechanism 16 stops moving. The horizontal pushing cylinder 119 drives the push plate assembly 118 to push the toter box to the specified position. The vertically placed advancing cylinder 112 above the toter box extends downward, and the suction assembly 117 connected thereto is suctioned to the toter box. The vertically placed advancing cylinder 112 retracts to drive the toter box to lift. The horizontally placed advancing cylinder 112 above extends to convey the toter box to the cleaning machine station. The suction assembly 117 releases the toter box, and the advancing cylinder 112 retracts to complete the action.

[0064] The embodiment also provides a stacking machine related structure. Referring to Figures 7-11 The main structure of the stacking machine is as follows.

[0065] The main structure of the stacking machine is as follows.

[0066] In the embodiment, a group of lifting assemblies 23 is arranged on each side of the conveying assembly 25, and the lifting assemblies 23 are mainly used for lifting when the totes are stacked. Specifically, the lifting assembly 23 comprises a lifting frame 28 and a lifting driving mechanism 22. The lifting driving mechanism 22 mainly comprises a lifting motor, a chain wheel, a chain and the like, and the lifting frame 28 is connected to the chain. Under the driving of the lifting driving mechanism 22, the lifting frame 28 can move up and down along the main support assembly 21, so as to realize the lifting of the totes. In the embodiment, the lifting frames 28 on the two sides are driven to realize synchronous movement by the same group of lifting driving mechanisms 22. As a preferred structure of the lifting assembly 23, in the embodiment, a plurality of vertical supporting square steels 218 are arranged on the main support assembly 21, and the lifting assembly 23 further comprises three groups of lifting rollers 216 installed on the lifting frame 28. The three groups of lifting rollers 216 are arranged on three different sides of the vertical supporting square steels 218 respectively, and the lifting frame 28 moves up and down by moving along the vertical supporting square steels 218 through the three groups of lifting rollers 216. Meanwhile, a limiting plate 215 is arranged on the top of the vertical supporting square steel 218 to limit the limit position of the lifting frame 28. Through the structural design of the three groups of lifting rollers 216, the stability of the lifting frame 28 in the lifting movement can be ensured.

[0067] In the embodiment, two groups of clamping assemblies 26 are respectively installed on the corresponding lifting frames 28, and the clamping assemblies 26 can move up and down synchronously with the lifting frames 28. The clamping assembly 26 mainly comprises a clamping frame 29, a clamping cylinder 210 for driving the clamping frame 29 to move to realize the clamping of the totes, and clamping guide rollers 217. When the clamping frames 29 of the two groups of clamping assemblies 26 move inward, the totes can be clamped on both sides. When the clamping frames 29 of the two groups of clamping assemblies 26 move outward under the driving of the clamping cylinder 210, the totes can be loosened. The clamping cylinder 210 is fixed on the lifting frame 28, and the clamping frame 29 can move relative to the lifting frame 28. The clamping frame 29 is guided by the three groups of clamping guide rollers 217 arranged on the three sides of the lifting frame 28, so as to ensure the stability of the clamping frame 29 when moving.

[0068] In the embodiment, the guide rod assembly 24 is installed on the main support assembly 21 to limit and guide the totes when the totes are stacked. Specifically, the guide rod assembly 24 comprises a plurality of guide rods 213, which are divided into three groups and arranged on the two sides of the conveying assembly 25 and the incoming direction of the main support assembly 21. The guide rods 213 are installed through guide rod supports 214, and the guide rods 213 and the guide rod supports 214 are connected through bolts and straight slots. Therefore, the extension length of the guide rods 213 can be adjusted, and the totes of different sizes can be limited.

[0069] In the embodiment, the limiting and releasing assembly 27 is located behind the lifting assembly 23, and is used for limiting the turnover box when stacking and releasing the turnover box after stacking. Specifically, the limiting and releasing assembly 27 comprises two limiting frames 211 and a releasing cylinder 212. The limiting frames 211 are rotatably installed on the main support assembly 21 through rotary supports, and the limiting frames 211 are connected with the releasing cylinder 212. When the releasing cylinder 212 extends and retracts, the limiting frames 211 can be controlled to rotate. Under the action of the releasing cylinder 212, the limiting frames 211 are rotated to the upper side of the conveying assembly 25 to block the turnover box, so as to limit the turnover box. When the limiting frames 211 are rotated to the outer side of the conveying assembly 25, the turnover box is released.

[0070] The main working principle of the stacking machine in the embodiment is as follows:

[0071] When the turnover box is conveyed to the stacking machine station, the clamping frames 29 on both sides of the turnover box are tightened under the drive of the clamping cylinder 210, the power assembly drives the lifting assemblies 23 on both sides to rise, at this time, the next turnover box is conveyed to the station, the power assembly drives the lifting assemblies 23 to descend, the clamping cylinder 210 retracts, the clamping frames 29 loosen the turnover box, and the turnover box falls onto the turnover box below, completing a stacking; when the lifting assemblies 23 descend to the lowermost position, the clamping cylinder 210 extends, the clamping frames 29 on both sides clamp the lowermost turnover box, the power assembly drives the lifting assemblies 23 to lift the two turnover boxes, when the third turnover box reaches the station, the above steps are repeated, and the stacking is completed. When the turnover boxes are stacked to the required number, the releasing cylinders 212 on both sides retract, the limiting frames 211 on both sides rotate along the hinge seat assembly, at this time, the limiting of the turnover box in the conveying assembly 25 is released, the conveying assembly 25 outputs the stacked turnover boxes, and moves to the next station.

[0072] The cleaning line provided in the embodiment breaks the previous scheme that the lifting mechanism and the clamping mechanism are separately arranged and the stacking is performed from bottom to top, and instead, the clamping assembly and the clamping cylinder are fixed on the lifting assembly, the turnover box is clamped first and then lifted, and the stacking is performed from top to bottom. The structure is more compact and reasonable, and the stability of the turnover box during stacking can be better guaranteed.
