Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to a hospital linen distribution system. Background Art

[0002] Linen mainly refers to bed sheets, quilt covers, pillowcases, mattresses and other items in the ward. The main dirt is protein stains such as human sebum, dandruff, excrement, blood stains, pus stains, etc. Doctors', nurses' and patient gowns are mainly disinfected and washed. Doctors' and nurses' gowns, in particular, must meet the quality standards of the laundry industry and the disinfection standards of the health system.

[0003] At present, the hospital's method of storing linens is to use a linen cart described in CN205821850U for collection. The linen cart includes a frame body, a roller is provided at the bottom of the frame body, one side of the frame body is open, a bottom plate and at least one storage plate are provided on the frame body, the storage plate is located above the bottom plate, and the storage plate is slidably connected to the frame body. The frame body of the linen cart is provided with at least two layers of structures for placing linens including the bottom plate, so that the linens can be placed in categories; at the same time, the multi-layer placement structures are arranged side by side from top to bottom, so that the operator does not need to bend down when taking and placing each layer, making the operation more convenient.

[0004] However, the aforementioned linen cart still requires users to manually stack and store linens. For large bed sheets, quilt covers and other linens, users will have a hard time stacking them. In addition, the linens will naturally expand after being placed in the linen cart, further reducing the amount of linens that the linen cart can collect. When taking out the linens collected by the linen cart for washing, users need to take out the linens stacked deep in the linen cart. This process is still time-consuming and laborious. For this reason, we propose a hospital linen distribution system. Summary of the invention

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] Reference Figure 1-6 A hospital linen distribution system comprises a linen delivery cabinet 1 and a linen transport vehicle 2. The linen delivery cabinet 1 has a parking room 101 capable of allowing the linen transport vehicle 2 to be placed in the parking room 101. After the linen transport vehicle 2 is placed in the parking room 101, the user can drop the linens from doctors, nurses and patients from three different delivery ports 102 of the linen delivery cabinet 1 into three different collection bins 201 of the linen transport vehicle 2, thereby realizing the classified collection of linens.

[0031] The linen transport vehicle 2 includes a movable bottom plate 21 and a tipping bucket 22 installed on the upper end of the movable bottom plate 21, the interior of the tipping bucket 22 is divided into three collecting bins 201, the upper front end of the collecting bin 201 is provided with a collecting bucket 23, the upper part of the collecting bucket 23 is open and connected with the collecting bin 201, the linens put into the delivery port 102 will be received by the upper opening of the collecting bucket 23 under the guidance of the upper channel of the linen delivery cabinet 1, and slide into the collecting bin 201 along the lower inclined plate of the collecting bucket 23, when the linens in the collecting bin 201 are piled up to a certain height and detected by the detection and control component 24, the compaction plate 25 stacked on the upper part of the collecting bin 201 will be lowered, so that the originally fluffy stacked linens can be compacted by their own weight to make more stacking space.

[0032] The upper part of the movable bottom plate 21 is provided with a flipping drive motor 221 located on both sides of the flipping bucket 22, and the flipping drive motor 221 is connected to the rear bottom angle shaft of the flipping bucket 22. After being powered on, the flipping drive motor 221 can drive the flipping bucket 22 to flip backwards 90 degrees with the connecting shaft at the rear bottom angle as the rotation axis, so that the rear side plate of the flipping bucket 22 is arranged downward, and the rear side plate of the flipping bucket 22 has a discharge port 202 sealed by a flip sealing plate 222, and the upper end of the flip sealing plate 222 is connected to the side wall rotation shaft of the discharge port 202. The lower end of the plate 222 can be releasably locked to the bottom end of the discharge port 202. When the tipping bucket 22 is vertically arranged on the upper part of the movable bottom plate 21, the flip sealing plate 222 is vertically locked in the discharge port 202 so that the linens can be collected and stacked in the collecting bin 201. After the tipping bucket 22 is flipped, the flip driving motor 221 drives the upper end of the flip sealing plate 222 to unlock the discharge port 202, and the flip sealing plate 222 flips vertically downward to open the discharge port 202. The linens in the collecting bin 201 will move downward under the action of their own gravity and be discharged from the collecting bin 201.

[0033] When the tipping bucket 22 is turned over by 90 degrees and laid flat, the compacting plate 25 can be pulled back to the top of the collecting bin 201 by the pulling assembly 26 .

[0034] The bottom plate of the mobile bottom plate 21 can be adapted to the AGV robot, and a push armrest is fixedly installed on the upper surface of the mobile bottom plate 21. After the collection bin 201 is full of linens, the user or the AGV robot can drive the linen transport vehicle 2 to move to the designated unloading location to unload the linens.

[0035] Example 2

[0036] Reference Figure 1-6 The difference between this embodiment and embodiment 1 is that the left and right side walls of the collecting bin 201 have two mutually parallel vertical limit rails 203, and the left and right sides of the compacting plate 25 have limit heads 251 adapted to the vertical limit rails 203, and the limit heads 251 are slidably arranged on the vertical limit rails 203, so that the compacting plate 25 can only move vertically in the collecting bin 201 in a horizontal state, and the compacting plates 25 are provided in plurality and stacked on the upper part of the collecting bin 201, and each of the compacting plates 25 is provided with a lifting block 252 on the left and right sides, and the horizontal positions of the lifting blocks 252 of each of the compacting plates 25 are staggered with each other, and the space near the lifting blocks 252 is vacated so that the upper and lower spaces of each of the lifting blocks 252 are not blocked.

[0037] A central insertion cavity 204 is installed at the center of the compaction plate 25, and each of the left and right inner walls of the central insertion cavity 204 has a stop-drop socket 205. The detection and control component 24 includes a fixed box 241, a lower hanger 242 and a vertical movement box 243. The upper end of the fixed box 241 is fixedly installed on the top plate of the collection bin 201 and inserted into the central insertion cavity 204 of each compaction plate 25 stacked up and down. The vertical movement box 243 is arranged in the internal hollow fixed box 241, and the lower hanger 242 is arranged at the lower end of the vertical movement box 243 and extends from the lower end of the fixed box 241.

[0038] The collecting bucket 23 is provided with an axial rotating plate 27, the upper end of which is connected to the rotating shafts of the left and right side walls of the collecting bucket 23, and the lower end of which is connected to the vertical moving box 243 through a linkage rope 244, and the connecting end of the linkage rope 244 and the axial rotating plate 27 is located on the side of the axial rotating plate 27 away from the collecting bin 201. The linens put in from the delivery port 102 will fall into the collecting bucket 23 from the front of the axial rotating plate 27, and will push the axial rotating plate 27 to flip toward the collecting bin 201 during the falling process, thereby pulling the linkage rope 244 out of the fixed box 241 to hang the vertical moving box 243, and after the linens move away from the axial rotating plate 27 and fall into the collecting bin 201, the vertical moving box 243 will fall again.

[0039] In this way, before the linens enter the collecting bin 201, the lower hanger 242 will move up with the vertical movement box 243 without affecting the smooth entry of the linens into the collecting bin 201. After the linens successfully enter the collecting bin 201, the lower hanger 242 can fall again to detect the vertical height of the linens at the top.

[0040] A docking chamber 245 leading to the outside is arranged at a position on the side wall of the fixed box 241 corresponding to each stop socket 205. A stop slider 246 with a horizontal upper surface and an inclined lower surface is arranged in the docking chamber 245. When the stop slider 246 is inserted into the stop socket 205, the compacting plate 25 cannot fall. The stop slider 246 is connected to a damping member 247 and a push-back spring 248 in the docking chamber 245, and the stop slider 246 can be attracted by magnetic force. The side wall of the vertical moving box 243 is provided with a magnetic attraction strip 249 corresponding to the docking bin 245. When the linens in the collecting bin 201 do not reach the predetermined stacking height, the vertical moving box 243 is at the bottom of the fixed box 241, and each docking bin 245 is above the vertical moving box 243. The anti-falling slider 246 is pushed out of the docking bin 245 by the push-back spring 248 and inserted into the anti-falling socket 205 of each compacting plate 25 to keep the compacting plate 25 at the top of the collecting bin 201.

[0041] The damping member 247 can prevent the anti-falling slider 246 from quickly retracting into the docking bin 245 when it is attracted by the magnetic force of the magnetic strip 249, so that in the short time when the linens push the axial rotating plate 27 to flip and pull the vertical moving box 243 upward, the anti-falling slider 246 will not immediately retract into the docking bin 245 and lower the compacting plate 25. Only when the linens in the collection bin 201 reach a predetermined stacking height and the lower hanger 242 and the vertical moving box 243 are pushed up and maintained, the upward magnetic strip 249 will continue to attract the anti-falling slider 246 until it is completely retracted into the docking bin 245, thereby finally lowering the compacting plate 25.

[0042] Example 3

[0043] Reference Figure 1-6 The difference between this embodiment and embodiment 2 is that the pullback assembly 26 includes an elastic spring 261, a force transmission cable 262 and a hanging beam 263. One end of the elastic spring 261 is fixedly installed on both sides of the collecting bin 201, and the other end is connected to the force transmission cable 262. The hanging beam 263 is horizontally mounted on the top of the collecting bin 201. The force transmission cable 262 extends upward and passes around the hanging beam 263 and is connected to each hanging block 252. The self-gravity of the compacting plate 25 is much greater than the elastic force that the elastic spring 261 can provide when it is stretched. After the anti-fall slider 246 retracts the docking bin 245 and lowers the compacting plate 25, the compacting plate 25 can smoothly overcome the upward elastic force of the elastic spring 261 and fall to compact the linens.

[0044] When the tipping bucket 22 turns over to unload, the compacting plate 25 and the elastic spring 261 will change from the original vertical pulling relationship to a horizontal pulling relationship. The elastic spring 261, which was originally unable to pull up the compacting plate 25, can pull the compacting plate 25 laterally toward the position of the detection and control component 24 in sequence until it returns to its original position after the linens are discharged. When each compacting plate 25 returns to its original position, the hypotenuse of the stop slider 246 is pushed back to the docking bin 245 by the force and then pushed out by the push-back spring 248, thereby re-locking the compacting plate 25 at the top of the collection bin 201 to prepare for receiving the next batch of linens.
