Problems solved by technology
Since the main door and the small door of the freeze dryer are closed most of the time, it is inconvenient for human detection
Due to artificial missed inspection, the plywood will crush the material tray or even damage the plywood during the falling process.

Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] Figure 1 to Figure 3 An embodiment of the method for detecting a tray of a freeze dryer according to the present invention is shown, comprising the following steps:
[0025] S1: Establish a detection area: establish a laser detection ray in the material inlet and outlet area of the freeze dryer box 1. The laser detection ray matches the length of the carrier tray 2 and the plate layer 3, and the horizontal plane where the laser detection ray is located passes through the thickness of the tray 2. the space formed;
[0026] S2: Feeding: the unloaded layer 3 descends to the feeding and discharging area, and the material is fed sequentially from the top to the bottom of the layer 3 and rises layer by layer;
[0027] S3: Feed inspection: In the process of step S2, the real-time feedback of whether the laser detection ray has th...

The invention discloses a freeze dryer charging tray detection method. The freeze dryer charging tray detection method includes the following steps that S1, laser detection rays are established in a feeding-discharging area and are matched with the lengths of a bearing charging tray and plate layers, and the horizontal plane of the laser detection rays penetrates through the space formed by the thickness of the charging tray; S2, the no-load plate layers are lowered to the feeding-discharging area, feeding is sequentially conducted according to the order from the tops to the bottoms of the plate layers, and ascending is conducted layer by layer; S3, signals of whether the laser detection rays are blocked by the charging tray or not are fed in real time, and identifiers with the charging tray and identifiers without the charging tray are set to correspond to all the plate layers according to the feedback signals; S4, discharging is sequentially conducted according to the order from thebottoms to the tops of the plate layers, and descending is conducted layer by layer; and S5, the identifiers are judged, if the identifiers are the identifiers with the charging tray, the upper layerof the plate layers can stop descending, and if the identifiers are the identifiers without the charging tray, the upper layer of the plate layers can descend normally. The freeze dryer charging traydetection method has the advantages that real time and high efficiency are achieved, stability and reliability are achieved, and the charging tray or the plate layers can be prevented from being damaged.
Description
technical field [0001] The invention mainly relates to the field of food and pharmaceutical packaging, in particular to a detection method for a feed tray of a freeze dryer. Background technique [0002] Raw material freeze dryers generally use trays for loading, and then place the trays on the layers of the freeze dryer for freeze-drying. In the prior art, there is a lack of detection methods for automatic identification of the trays on the sheets. Generally, operators Visually confirm the presence of trays on the ply. Since the main door and the small door of the freeze dryer are closed most of the time, it is inconvenient to detect manually. Due to artificial missed inspection, the plywood will crush the material tray or even damage the plywood during the falling process of the plywood. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a real-time, efficient, sta...
