Description
Technical Field
The invention belongs to the technical field of material transmission, and particularly relates to a track transmission device.
Background
The ethylene oxide sterilizer is a device for performing low-temperature fumigation sterilization on articles sealed in a sterilization chamber by using ethylene oxide gas with a certain concentration under the conditions of a certain temperature, a certain pressure and a certain humidity. The ethylene oxide gas used by the ethylene oxide sterilizer is an effective low-temperature sterilizing agent and is widely applied at home and abroad. However, ethylene oxide is a highly toxic, flammable and explosive chemical, and its safety must be especially taken into account during sterilization.
Before the ethylene oxide sterilizer performs sterilization, packaged articles to be sterilized are conveyed into a sterilization box body, stacked in the box body according to the specified requirements, then a box body sealing door is closed, and ethylene oxide gas is introduced according to the specified requirements and procedures for sterilization. After the sterilization is finished, the gas stays for a period of time after the sealing door is opened, and toxic residual ethylene oxide gas in the box body is forcibly discharged by a fan and then the sterilized objects are carried out.
At present, the following methods are generally adopted for the conveying of sterilized articles in a large sterilizer in the loading and unloading of the sterilized articles in a box body:
1) Push-pull method for manual trolley
Manually placing a trolley (an inner trolley) on a special outer trolley, manually stacking articles on the trolley, then pushing the outer trolley together with the inner trolley onto two trolley rails in a sterilizer box body, and then entering the box body by a worker to push the trolley on the rails together with the sterilized articles to the other end (or the other door) of the box body from a door. Multiple carts are advanced in the same manner until the sterilizer cabinet is full. After the sterilization is finished, the door is opened, and after the concentration of residual ethylene oxide gas in the box body is reduced to be below the requirement, the trolley at the door is manually pulled to an outer vehicle to be pulled away. Then the second vehicle is pulled to the door opening after entering the box body manually, and then is pulled to a special outer vehicle for pulling away. The same process is repeated several times until all carts and items are unloaded. For the two-door sterilizer, the same procedure was followed for unloading the sterilizer from the other door.
2) Forklift transportation method
And (4) loading the tray filled with the sterilized objects into the last position of the box body by using a forklift, and then filling the box body in sequence. During unloading, the trays at the door are conveyed away firstly, and then the trays in the box body are conveyed away in sequence by a forklift until the last tray is conveyed away.
3) Push-pull method for roller way of artificial tray
Two long fixed roller ways are arranged on two sides in the sterilizer body. During loading, the goods to be sterilized are loaded on a special tray, the tray is placed on the roller way by a forklift or other methods, and then the goods enter the box body manually to push the tray, so that the tray moves to the other end of the box body on the roller way. The above process is repeated several times until the tray is filled with the cases. After the sterilization is finished, the door of the single-door sterilizer is opened, and the single-door sterilizer can be unloaded after the residual ethylene oxide gas in the box body is dispersed. When unloading, the tray at the doorway is carried away by a forklift. And manually entering the box body to pull the second tray to the door opening, then using a forklift to carry the second tray away, and repeating the same method for multiple times until all the trays and the articles are completely unloaded. The double door sterilizer was unloaded from the other door in the same manner.
The main problems with these three methods are: during loading and unloading, workers need to enter the box body to push and pull the trolley or the tray, so that the physical labor amount is large, the working efficiency is low, the production rate is low, and sterilized products are easily damaged; after the door is opened after the sterilization is finished, residual ethylene oxide gas in the sterilized objects cannot be diffused completely, and a large amount of toxic ethylene oxide gas remains in the box body. To avoid toxic residual ethylene oxide gas that could harm the body. After the door is opened, workers cannot enter the box body immediately to push and pull out the trolley or the tray, and residual ethylene oxide needs to be discharged after forced diffusion or natural diffusion for a long time, so that the production efficiency is influenced.

The square steel pipes on the two sides of the trolley frame are respectively provided with a plurality of pairs (equal to the number of the trays) of outward movable push rod mechanisms 71 at equal intervals (the distance is equal to the length of the trays), and the outward movable push rod mechanisms 71 can only bear outward thrust but cannot bear inward thrust. The outward movable push rod mechanism 71 can only tilt outward and is installed in the middle of the trolley, and the main function is to push the tray 11 in the box body 12 outward (towards the doorway). The outward moving push rod mechanisms 71 are installed in pairs at the both sides of the cart according to the designed distance, as shown in fig. 1 and 5a.
The two symmetrical positions of the front side of the transmission trolley 4 are provided with a pair of inward movable push rod mechanisms 72, the installation direction of the inward movable push rod mechanisms is opposite to the direction of the outward movable push rod mechanisms, and the inward movable push rod mechanisms can only bear inward thrust and cannot bear outward thrust. The inwardly movable pusher mechanism 72 is only capable of tipping into the housing and has the primary function of pushing the tray 11 into the housing 12. When the trolley is pushed out to approach the doorway, the inward movable push rod mechanism 72 collides with the clamping plate 8, and the inward movable push rod mechanism 72 is pressed down towards the inner direction of the box body 12. So that the inward movable push rod mechanism 72 does not affect the loading and unloading of the pallet by the forklift. The catch plate 8 is mounted on the inside of the roller bracket 9 with a fourth bolt 81, see fig. 2. Only one pair of inward movable push rod mechanisms 72 are arranged on the two sides of the front end (door opening direction) of the trolley according to set positions, as shown in fig. 1 and 5a.

The first stopper pin 58 limits the position of the pull rod 51 in which it is pulled out, see fig. 5c, 5d (enlarged view of I in 5 c).
The pull rod handle 56 and the limiting hook 57 can be changed into a small cylinder, and the piston of the small cylinder extends out and retracts, so that manual control can be changed into pneumatic control.
Cylinder
The cylinder 3 is arranged in the middle of the sterilizer box body close to the door direction, and the piston rod stretches towards the door direction and is a power source for material transmission. The cylinder is fixed on the lower plane of the box body by a second bolt 31. The piston rod end of the cylinder is fitted with a universal joint 32 to protect the piston rod from or reduce lateral forces. The universal joint is connected with the front part of the trolley through a nut 33, and the trolley is pushed or pulled by the cylinder to move back and forth. After the sterilizer is filled with the sterilization equipment, the piston rod of the air cylinder is in a retraction state when the door is closed for sterilization work, so that the piston rod is protected from being polluted by ethylene oxide deposits in a sterilization work period, as shown in figure 1. The cylinder has a vent connection 34 at the front and a vent connection 35 at the rear for the introduction or removal of compressed air, see fig. 3.

The cylinder 3 is mounted in a casing 12, and various control valves of the apparatus are mounted in a control box outside the casing 12. The operating button of the transmission device is arranged on the panel of the control box. The main function of the control means (control valve) and the air circuit is to control the extension and retraction of the cylinder 3 so as to push out or advance the tray 11. The elements of the air circuit system are all pneumatic elements, see fig. 3. Besides the pneumatic device provided by the embodiment, the transmission device can also provide power for the transmission device through other power devices such as hydraulic devices, electric control devices and the like.
The working process of the pneumatic roller way transmission device is explained in detail by the specific embodiment.
This embodiment is suitable for use with a single door sterilizer having only one door, both the entry door and the exit door.
Loading propulsion process
1) Preparation for loading
The sterilizer door is opened, the gas path system is connected with the gas source, the push button (the air vent at the rear part of the cylinder is ventilated, the air vent at the front part is exhausted, the same is applied below) is pressed to push the piston rod of the cylinder 3 out of a cylinder stroke L, and the trolley is pushed forwards to the door of the box body 12 by the piston rod, as shown in figure 6. The inward moving push rod mechanism 72 in the standing state before the trolley reaches the terminal point falls inward after touching the clamping plate 8, and the height is lower than the upper plane of the roller. And stopping the trolley after the terminal point is reached. At this time, the limit hook 57 on the pull rod 51 should be disengaged from the end hole of the longitudinal beam of the trolley, and all the outward-moving push rod mechanisms 71 on the trolley are in a falling state, as shown in fig. 5a.
2) Load the 1 st tray
The pallet is placed in front of the roller table 2 by a forklift or other means, and the distance from the front end of the pallet 11 to the edge of the clamping plate is larger than a set distance a, see fig. 5a.
3) Advance the 1 st tray
The push button (the front vent hole of the cylinder is used for ventilation, the rear vent hole is used for exhaust, the same is applied below) is pressed, and the piston rod pulls the trolley to move towards the box body. After moving a short distance, the inward movable push rod mechanism 72 mounted on the cart automatically stands up after leaving the card board 8, and after moving continuously, the inward movable push rod mechanism 72 contacts the front of the 1 st tray, see fig. 5b. The trolley continues to move, the inward movable push rod mechanism 72 pushes the tray 11 forward, and after the piston rod reaches the end point, the tray stays on the roller way 2 (because the outward movable push rod mechanisms are all in the falling state, the tray movement is not hindered).
4) Load the 2 nd tray
And when the push button is pressed, the piston rod pushes the trolley to move towards the outside of the box body 12. When the trolley moves outwards, the inward movable push rod mechanism 72 keeps in an upright state, and the inward movable push rod mechanism 72 falls inwards after touching the clamping plate 8 before the trolley reaches the terminal point, and the height of the inward movable push rod mechanism is lower than the upper plane of the roller. And stopping the trolley after the terminal point is reached. The 2 nd tray was set on the roller table in the same position as the 1 st tray in the foregoing manner.
5) The 2 nd tray is pushed to the position of the original first tray by pushing the first tray, and the 1 st tray is pushed by the 2 nd tray to the distance of one tray in the box body 12 and stays on the roller way.
6) Loading and advancing the remaining pallets
The loading of the remaining trays is repeated a number of times as described above. After the last 2 nd tray is loaded and pushed in, the air cylinder is not pushed out any more, so that the piston rod is kept in the cylinder body, as shown in figure 1.
7) Load the last tray
The last 2 nd pallet is pushed into the rear cylinder and kept still, and the last pallet is placed in the front of the roller way at the same position as other pallets are loaded. The sterilization operation may be performed by closing the door after loading the last tray.
Unloading push-out process
1) Unloading preparation
The sterilizer door is opened, and the external air source air path of the control part is connected.
2) Unload 1 st tray (get up close to the door end, the same below)
The 1 st pallet near the doorway end is removed with a forklift or other method.
3) Unloading 2 nd tray
And when the push button is pressed, the piston rod pushes the trolley to move towards the outside of the box body 12. Two fixed push rods 1 arranged at the rear part of the trolley are contacted with a tray (in the box body) at the rearmost part after a certain distance b along with the idle stroke of the trolley (see figure 1) and are pushed forward for a tray distance together with all the trays. The 2 nd tray near the doorway is pushed to the doorway and the tray is unloaded with a forklift.
After the 2 nd pallet is unloaded, the pull rod handle 56 is pulled forwards and the limiting hook 57 is hung in the hole at the end of the longitudinal beam of the trolley, so that the resistance at the lower end of all outward movable push rod mechanisms 72 is released completely, the push rods automatically form a standing trend, and the small roller at the top is contacted with the bottom of the pallet.
4) Unloading No. 3 tray
The push button is pressed and the piston rod pulls the trolley to move towards the interior of the box body 12. When the travel is over, the last push rod behind the trolley is separated from the tray above and automatically erected, other push rods are still positioned below the tray, and the small roller at the top end of the push rod is in contact with the bottom of the tray and relatively rolls in the process of retreating the trolley.
And when the push button is pressed, the piston rod pushes the trolley to move towards the outside of the box body 12. The last two outward moving push rod mechanisms 71 arranged at the rear part of the trolley are contacted with a tray (in the box body) at the rearmost part after a certain distance along with the idle stroke of the trolley and are pushed forward for a tray distance together with all other trays, the 3 rd tray close to the doorway is pushed to the doorway end, and the tray is unloaded by a forklift.
5) Repeat the above operation of serial No. 4), sequentially move the 4 th, 5 th, … … until the last tray is discharged.
The loading and unloading process of the sterilized object can be completed by the above operation.
The pneumatic roller way transmission device can be used for bidirectional transmission of a single-door sterilizer which is pushed by the same door for loading and unloading, and can also be used for a double-door sterilizer through simple adjustment, so that unidirectional transmission of pushing by one door for loading and pushing and unloading by the other door is realized. When the device is used for unidirectional transmission, the functions of pushing by the feeding door (see figure 7 a) and withdrawing by the discharging door (see figure 7 b) can be realized by only canceling two fixed push rods 1 and the push rod control mechanism 5 in the structure and changing all outward movable push rod mechanisms 71 into inward movable push rod mechanisms 72. The loading and unloading operations are the same as the pushing operation of the single-gate two-way transfer.
The pneumatic rail transmission device provided by the embodiment is applied to single-door bidirectional transmission.
A single-door ethylene oxide sterilizer, the length of a box body is 9600mm, a pneumatic trolley push-pull type roller bed semi-automatic material conveying device is installed, single-door propelling and push-out conveying is achieved, 8 trays with the length of 1100mm are conveyed, and the load of each tray is 300kg. Only one person is needed to operate each time one tray is conveyed, and the operation is finished by pressing the button for 2 times. And the manual push-pull work is not needed, each tray is loaded for only 1 minute, and 8 trays can be loaded or unloaded in ten minutes. The device ensures that workers do not need to enter a toxic environment in the box body, avoids direct contact with toxic gas, reduces operators and improves the productivity.
The unloading of the sterilizer after sterilization needs 3 persons for 1 hour (including the emission time of residual ethylene oxide gas) according to the existing manual tray roller way push-pull method. The unloading of the transfer device according to the invention can be completed (including the aid time) in only 2 persons and half an hour. The number of people is reduced by 30%, and the efficiency is improved by 2 times. And ensure that the workers do not need to enter the toxic environment in the box body, avoid direct contact with toxic gas and ensure the health.
