Based on the above description, in a method for demolding a tray according to the present invention (taking a front view direction as an example):
step one: the tray transferring slide rail 5 transfers the tray 11 containing food from the previous mechanical structure to the upper sides of the first support arm 41 and the second support arm 42, specifically, the first slide rail 51 and the second slide rail 52 transfer the tray 11 to the upper sides of the first support arm 41 and the second support arm 42. In the initial position, the first roll-over stand 4 and the second roll-over stand 6 are flat, the initial positions of the first rail climbing vehicle 7 and the second rail climbing vehicle 8 are respectively at two ends of the semicircular track 2, namely, the initial position of the first rail climbing vehicle 7 is at one side of the first roll-over stand 4 far away from the main shaft 1, and the second rail climbing vehicle 8 is at one side of the second roll-over stand 6 far away from the main shaft 1.
Step two: the third motor 103 is started, the third motor 103 drives the second holding strip 102 to approach the first holding strip 101, and the first holding strip 101 and the second holding strip 102 are embedded into the grooves of the baking tray 11 from two sides and jointly clamp the baking tray 11.
Step three: the second motor 85 is started, the third gear 82 and the fourth gear 83 move along the first toothed chain 22 and the second toothed chain 24, that is, the second track climbing car 8 moves along the semicircular track 2, the second track climbing car 8 drives the third bracket arm 61 and the fourth bracket arm 62 to move so that one side of the conveying mechanism 3 moves along the semicircular track 2, the conveying mechanism 3 turns clockwise towards the bakeware 11 until the conveyor belt 34 covers on the upper surface of the bakeware 11, the covering means that the conveyor belt 34 covers on the port of each grid on the bakeware 11, the conveyor belt 34 can prevent food from falling out of the grid even if the bakeware 11 is inclined, and then the second motor 85 is stopped (the stopping here is to prevent collision damage between the first turnover frame 4 and the second turnover frame 6, so that the reverse starting of the first motor 75 and the second motor 85 in the fourth step is not stopped).
Step four: simultaneously, the first motor 75 and the second motor 85 are reversely started, the first motor 75 drives the first gear 72 and the second gear 73 to move along the first toothed chain 22 and the second toothed chain 24 respectively, the second motor 85 drives the third gear 82 and the fourth gear 83 to move along the first toothed chain 22 and the second toothed chain 24 respectively, therefore, the first rail climbing car 7 drives the first supporting arm 41 and the second supporting arm 42 to lift and rotate the baking tray 11, the second rail climbing car 8 drives the third supporting arm 61 and the fourth supporting arm 62 to lift and rotate the conveying mechanism 3, the speed of the first rail climbing car 7 and the speed of the second rail climbing car 8 are the same, the baking tray 11 and the conveying mechanism 3 rotate anticlockwise together in a covering state, and the baking tray 11 is continuously clamped by the chuck assembly 10 in the rotating process. Until the conveyor 3 returns to the initial position, the first motor 75 and the second motor 85 are stopped, the bakeware 11 is reversely buckled on the conveyor 34 at this time, and the food is released from the mold by its own weight and remains on the conveyor 3.
It is known that after the tray 11 rotates more than 90 degrees, the food in the tray 11 will start to separate from the tray 11 due to gravity, and the conveyor belt 34 always covers the openings of the lattices in the tray 11 during the tray turning process of the tray 11, so that the food will not fall during the tray turning process.
Step four: the first motor 75 is started, the first rail climbing vehicle 7 moves along the first guide rail 21 and the second guide rail 23, the baking tray 11 starts to turn clockwise and is far away from the conveyor belt 34, food originally in the grids of the baking tray 11 can stay on the conveyor belt 34, and the food stays on the conveyor belt 34 in the array mode of the grids in the original baking tray 11, so that the subsequent processing of the food is facilitated. The first rail climbing vehicle 7 is stopped until the first roll-over stand 4 returns to the initial position, and the baking tray 11 is restored to the flat state.
Step 5: the third motor 103 is started to drive the second holding strip 102 away from the first holding strip 101, so that the holding of the baking tray 11 is released.
