It should be noted that when the limiting piece extends out to support the bottom of the tray, the limiting piece 143 does not interfere with the tray support 164 .

Specifically, the working sequence of the tray discharging mechanism 170 is opposite to that of the tray loading mechanism 160. When the trays in the third tray temporary storage area 140 reach a set number or a set height, the tray support moves to The highest position supports the bottom surface of the bottom tray, and the limit piece of the third tray temporary storage area 140 is retracted, and the stacked trays are moved downwards under the drive of the tray inlet and outlet channels between the trays to reach the bottom of the tray. At the lowest position of the support, the tray is supported by the tray placement frame, and then the second linear drag mechanism of the tray discharge mechanism drives the tray placement frame to move out to realize automatic discharge, and the removed tray is manually removed.

Further, the first tray temporary storage area 120, the second tray temporary storage area 130, and the third tray temporary storage area 140 are arranged at equal intervals in sequence, and the distance between the two bracket mechanisms 152 and the first straight line The stroke of drag mechanism 151 is equal to the distance between the first material tray temporary storage area, the second material tray temporary storage area, and the 3rd material tray temporary storage area, so that the first linear drag mechanism 151 is moved from the initial position (two The bracket mechanism 152 is located below the first tray temporary storage area 120 and the second tray temporary storage area 130) after moving the maximum stroke, the two bracket mechanisms 152 just move synchronously to the second tray temporary storage area 130 and the third tray storage area 130. Below the disk temporary storage area 140, the high accuracy of the transfer is ensured, and the error in the position is avoided to cause the failure of the tray transfer.

The specific transfer principle is:

S1: Initial position, the two tray brackets are respectively (from left to right) located directly below the second tray temporary storage area 130 and the first tray temporary storage area 120;

S2: The upper bracket moving component 1522 drives the bracket 1521 to move up to the highest position (see the bracket 1521' in Fig. 2 for details), at this time the limit of the first tray temporary storage area 120 and the second tray temporary storage area 130 The sheet is retracted, the tray in the first tray temporary storage area 120 falls on the bracket 1521, and the tray located in the second tray temporary storage area 130 falls on the other bracket 1521, and the time limit is set after a delay. The sheet is stretched out, and the tray inlet and outlet channels of the first tray temporary storage area 120 and the second tray temporary storage area 130 are closed;

S3: The upper support moving component 1522 drives the bracket 1521 to move down to the initial position;

S4: After the first linear drag mechanism 151 drives the two brackets 1521 to linearly move to the maximum stroke, the two brackets 1521 translate to the right below the third tray temporary storage area 140 and the second tray temporary storage area 130;

S5: The upper bracket moving component 1522 drives the bracket 1521 to move up to the highest position, and the limiting pieces of the second temporary storage area 130 and the third temporary storage area 140 are retracted, so that the first temporary storage area The trays in the tray are transferred to the second tray temporary storage area, and the trays in the second tray temporary storage area are transferred to the third tray temporary storage area. After the delay setting time, the limit piece extends out to re-open the tray inlet and outlet Channel restriction;

S6: The upper bracket moving component 1522 drives the bracket 1521 to move down to the initial position, and the first linear drag mechanism drives the bracket 1521 back to the initial position;

S7: cycle through steps S2-S6.

It should be noted that, while step S7 reaches the execution step S5 of the last cycle of the set number of cycles, the tray feeding mechanism 160 acts to replenish the tray in the first tray temporary storage area; Simultaneously with the execution of step S6 in the last cycle of the number of cycles, the tray discharging mechanism 170 operates to remove the trays in the third tray temporary storage area.

The foregoing embodiments are only preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore: all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered by this utility model. within the scope of protection of utility models.
