Description

Automatic culture medium filling device

Technical Field

The invention relates to an automatic culture medium filling device applied to the fields of pharmacy, food and beverage, disease control, chemical industry, cosmetics and the like.

Background

At present, most production enterprises adopt the following three modes for subpackaging and filling plates:

manual subpackage is carried out, the production efficiency is low, the cost is high, the risk of pollution of the product is high, and the filling quality is difficult to ensure.

Adopt full-automatic partial shipment production line to carry out the partial shipment, although personnel's demand is less than the manual work, and production efficiency is high, but the maintenance cost in equipment cost itself and later stage is high, can not satisfy most culture medium automatic filling, and is higher to the requirement of environment, and equipment need occupy than great factory building area, causes the waste of resource to the enterprise of small batch production.

Adopt carousel style partial shipment appearance to carry out the partial shipment, can solve the cost of labor height in theory, filling quality is unstable, and equipment volume is too big, requires the high scheduling problem, but the partial shipment appearance of present carousel type has following problem:

1. in the operation process, no matter the empty plate is located or the full plate is lifted, the rotating disc needs to rotate in a reciprocating mode, the plate is possibly clamped and even damaged due to the reciprocating rotation of the large-mass rotating disc, the culture medium is further polluted, the equipment is clean, and even microorganism breeding and other problems are caused. 2. Empty ware of installation or take off full ware and need take from the top, because the board height is higher, and the carousel that piles up the plate places again on the board, and the board only has outer lane part to place the plate moreover, and whole device volume and weight all can lead to personnel's operation fairly inconvenient, and full dish is folded whole carousel after full and is needed a plurality of staff to carry, and the risk of otherwise empting is very high.

3. The filled plate is used for microorganism inspection or monitoring, so the filled plate is theoretically sterile, and the rotary disc has a large volume, so the plate cannot be placed into a sterilization box for sterilization, and the manual sterilization difficulty is high.

4. Because the flat dish lid and flat dish are put on two upper and lower carousel mounts during the filling, the mount has the clearance, and will accomplish and rotate and the filling back, the knockout pin of jacking does not fix a position the flat dish, leads to the jacking to the in-process of above-mentioned large turntable, appears pushing away curved easily, closes the lid not to the position and presss from both sides the condition such as garrulous even.

5. Because the blanking hole and the jacking hole of current carousel are adjacent together, operating space is little, in case take place the card ware, perhaps take place when the knock-out lever rises that full ware interferes with the carousel, will take place to press from both sides garrulous plate ware, and the liquid flows into the condition of board, handles difficultly.
