Description

Technical Field

[0001] The present invention relates to the technical field of food and drug packaging machinery and equipment, and particularly relates to a sterilization tray, a sterilization tray bottle unloading device, a system and a method. Background Art

[0002] The existing sterilization tray is used in cooperation with a bottle protection plate and a bottle pushing plate for bottle body transportation. The sterilization tray includes a tray body and a gate plate. The tray body is formed by enclosing a bottom wall, side walls provided on both sides of the bottom wall, and a fixed end wall provided at one end of the bottom wall. One end of the tray body opposite to the fixed end wall is open to form a bottle outlet. A bottle pushing port through which the bottle pushing plate can pass is provided on the fixed end wall. Both ends of the gate plate are respectively hinged to the two side walls through connecting arms for opening and closing the bottle outlet. When the bottle outlet is closed, there is a bottle protection port between the gate plate and the bottom wall through which the bottle protection plate can pass. Since the connecting arms occupy the space on both sides of the sterilization tray, it is not convenient to stack the sterilization trays side by side. Moreover, the gate plate and the connecting arms are connected as a whole, and it is not convenient to open and close.

[0003] In the existing sterilization tray bottle unloading device, after the sterilization tray is opened on the conveying mechanism, the inner bottle bodies are pushed out integrally at one time to another conveying mechanism. Since there is a gap between the two conveying mechanisms, the conveying distance of the bottle bodies after being pushed out from the sterilization tray is long, and it is easy to have the situations of bottle toppling and bottle breaking. Moreover, the pushing tray mechanism needs to push the sterilization tray to the opening station at one time, and it is difficult for the sterilization tray to accurately reach the opening station, resulting in the sterilization tray not being able to be opened smoothly. Summary of the Invention

[0025] S7. The bottle pushing mechanism pushes the bottle body from the bottle unloading station to the bottle buffer station, and the bottle protecting mechanism protects the front side of the bottle body during the bottle pushing process of the bottle pushing mechanism.

[0026] Compared with the prior art, the advantages of the present invention are as follows:

[0027] For the sterilization tray of the present invention, during the opening process: press down the pressure-bearing rotating part, so that the lock block rotates under the action of overcoming the elastic force of the elastic part until the lock opening is separated from the gate to release the locking effect on the gate; then, rotate the gate to open it. First, the door lock mechanism of this sterilization tray is arranged at the top of the tray body, without occupying the space on both sides of the tray body, which is convenient for stacking side by side; second, the door lock mechanism of this sterilization tray has a simple structure, is a split structure with the gate, and is convenient to open and close.

After the sterilization tray is opened, the tray pushing mechanism first pushes the sterilization tray to the bottle unloading station, and then the bottle protecting mechanism pushes the bottle body in the sterilization tray from the bottle unloading station to the bottle buffer station. Since in actual use, the environments of the bottle unloading station and the bottle buffer station are different.

[0047] Embodiment Two:

[0048] Figure 4 An embodiment of the bottle unloading device of the sterilization tray of the present invention is shown. The bottle unloading device of this embodiment includes a pushing tray mechanism 41, a lifting and fixing tray mechanism 42, an unlocking mechanism 43, a rotary door opening mechanism 44, a bottle pushing mechanism 45 and a bottle protecting mechanism 46. The lifting and fixing tray mechanism 42 is used to position the tray body 1 at the fixed tray station. The pushing tray mechanism 41 is used to push the lifting and fixing tray mechanism 42 to move between the fixed tray station, the opening tray station and the bottle unloading station. The unlocking mechanism 43 is arranged on the lifting and fixing tray mechanism 42 and is used to press down the pressure-receiving rotation part 312. The rotary door opening mechanism 44 is used to open the gate 2 at the opening tray station. The bottle pushing mechanism 45 is used to push the bottles in the tray body 1 from the bottle unloading station to the bottle buffer station. The bottle protecting mechanism 46 is used to protect the front side of the bottles during the opening process of the gate 2 and the bottle pushing process of the bottle pushing mechanism 45.

[0049] The working process of this sterilization tray bottle unloading device is as follows: First, the lifting and fixing tray mechanism 42 descends to position the sterilization tray at the fixing tray station; Second, the tray pushing mechanism 41 pushes the lifting and fixing tray mechanism 42 to move, so that the sterilization tray moves from the fixing tray station to the opening tray station; Then, the unlocking mechanism 43 presses down on the pressure-receiving rotating part 312 to separate the locking port 311 from the gate 2; Next, the rotating door opening mechanism 44 opens the gate 2, and the bottle protecting mechanism 46 protects the front side of the bottle body during the opening of the gate 2; Then, the tray pushing mechanism 41 pushes the sterilization tray to the bottle unloading station again, and the bottle protecting mechanism 46 protects the front side of the bottle body during the tray pushing process of the tray pushing mechanism 41; Finally, the bottle pushing mechanism 45 pushes the bottle body from the bottle unloading station to the bottle body buffer station, and the bottle protecting mechanism 46 protects the front side of the bottle body during the opening of the gate 2 and the bottle pushing process of the bottle pushing mechanism 45. After the sterilization tray is opened, the tray pushing mechanism 41 first pushes the sterilization tray to the bottle unloading station, and then the bottle protecting mechanism 46 pushes the bottle body in the sterilization tray from the bottle unloading station to the bottle body buffer station. Since in actual use, the environments at the bottle unloading station and the bottle body buffer station are different. For example, the bottle body buffer station is located on a conveying mechanism, and the bottle unloading station is located between two conveying mechanisms. In this way, after the sterilization tray reaches the bottle unloading station and then unloads the bottle, the conveying length of the bottle body after being pushed out of the sterilization tray is reduced, thereby reducing the risk of bottle toppling and breaking. And, after the sterilization tray is positioned at the fixing tray station, it is then pushed by the tray pushing mechanism 41 to the opening tray station, so that the sterilization tray accurately reaches the opening tray station and is successfully opened.

[0050] In this embodiment, the bottle protecting mechanism 46 includes a first bottle protecting component 461 and a second bottle protecting component 462. The first bottle protecting component 461 is used to protect the front side of the bottle body during the opening of the gate 2, and the second bottle protecting component 462 is used to protect the front side of the bottle body during the bottle pushing process of the bottle pushing mechanism 45. The first bottle protecting component 461 is used to protect the front side of the bottle body during the opening of the gate 2 and during the process of the opened sterilization tray moving from the opening tray station to the bottle unloading station. The first bottle protecting component 461 protects the front side of the bottle body during the opening of the gate 2, that is, it replaces the gate 2 to block the bottle body to ensure that the bottle does not topple during bottle unloading. The first bottle protecting component 461 protects the front side of the bottle body during the process of the opened sterilization tray moving from the opening tray station to the bottle unloading station, to prevent the opened sterilization tray from toppling during the movement. The second bottle protecting component 462 is used to protect the front side of the bottle body during the bottle pushing process of the bottle pushing mechanism 45 to prevent the bottle from toppling during the bottle pushing process. By setting the first bottle protecting component 461 and the second bottle protecting component 462, the bottle protecting movement length of one bottle protecting component is reduced, and the selection range of the existing bottle protecting mechanism 46 is increased. The bottle protecting mechanism 46 includes a lifting component and a bottle protecting plate provided on the lifting component. The lifting component is a telescopic oil cylinder, a telescopic electric cylinder or a telescopic air cylinder.

[0051] In this embodiment, the lifting and positioning plate mechanism 42 includes a moving frame 421, a lifting seat 422 provided on the moving frame 421, and a lifting drive 423 for driving the lifting of the lifting seat 422. Two clamping blocks 424 for clamping and placing the plate body 1 and a clamping and placing drive 425 for driving the opening and closing of the clamping blocks 424 are provided on the lifting seat 422. The unlocking mechanism 43 and the bottle protecting mechanism 46 are both provided on the lifting seat 422, and the moving frame 421 is connected to the pushing plate mechanism 41. The lifting drive 423 drives the lifting seat 422 to descend until the two clamping blocks 424 are respectively located on both sides of the plate body 1, and then the clamping and placing drive 425 drives the two clamping blocks 424 to close to clamp the plate body 1, thereby realizing the positioning of the plate body 1. Then, the pushing plate mechanism 41 pushes the entire moving frame 421 and the plate body 1 to move.

[0052] In this embodiment, the sterilization tray bottle unloading device further includes a mounting frame 47. The moving frame 421 is movably arranged on the mounting frame 47, the pushing plate mechanism 41 is arranged on the mounting frame 47, and a lifting bottle blocking mechanism 48 for limiting the moving position of the bottle protecting mechanism 46 is also provided on the mounting frame 47.

[0053] When the sterilization tray after opening reaches the bottle unloading station, the bottle pushing mechanism 45 acts to push the bottle. At this time, the second bottle protecting component 462 moves forward synchronously to protect the front end of the bottle body. When pushing the bottle to the rear lifting bottle blocking mechanism 48, the second bottle protecting component 462 and the lifting bottle blocking mechanism 48 rise. The bottle pushing mechanism 45 completely pushes the bottle body to the bottle body buffer station.

The bottle body buffer station is arranged on the buffer mesh belt 61. The bottle blocking member 62 can block the bottle body on the buffer mesh belt 61 to realize buffering. Moreover, the bottle blocking member 62 can move along the conveying direction of the buffer mesh belt 61 to adjust the number of buffered bottle bodies. The bottle blocking member 62 provides a bottle body blocking force under the action of the gravity of the counterweight 64.

[0057] The buffer mesh belt 61 is connected to the bottle - conveying mesh belt 7, and the buffer mesh belt 61 and the bottle - conveying mesh belt 7 cooperate with each other to buffer and convey the bottles.

[0058] Below the tray - feeding conveyor mechanism 5, there is an empty - tray return mechanism. Between the tray - feeding conveyor mechanism 5 and the empty - tray return mechanism, there is a lifting and discharging tray mechanism. After the empty tray after bottle unloading is closed, it is lowered by the lifting and discharging tray mechanism to the empty - tray return mechanism for empty - tray return.

[0059] Embodiment 4:

[0060] A method for unloading bottles from a sterilization tray, which is carried out by using the sterilization - tray bottle - unloading system of Embodiment 3, includes the following steps:

[0061] S1. The tray - feeding conveyor mechanism 5 conveys the sterilization tray to the tray - fixing station;

[0062] S2. The lifting and tray - fixing mechanism 42 descends to position the sterilization tray;

[0068] After the sterilization tray is opened, the tray - pushing mechanism 41 first pushes the sterilization tray to the bottle - unloading station, and then the bottle - protecting mechanism 46 pushes the bottle body in the sterilization tray from the bottle - unloading station to the bottle - body buffer station.
