Example 1

As shown in fig. 1, the disc stacking device comprises a frame 7, wherein a disc stacking station 1, a disc stacking mechanism 6 in the disc stacking station 1, and a conveying mechanism arranged below the disc stacking station 1 are mainly arranged on the frame 7. Because the speed of conveying the seedling trays needs to be reduced in order to cooperate with the tray stacking mechanism 6 to stack the trays in the tray stacking process, if the acceleration and the deceleration of the seedling trays are controlled by one conveying mechanism, the control difficulty is high, and the seedling trays are difficult to form good cooperation with the tray stacking mechanism 6.

In order to solve the above problems, in this embodiment, the conveying mechanism is divided into two parts, as shown in fig. 2 to 4, each part is a tray stacking conveyor belt 2 disposed below the tray stacking station 1, and specifically includes two conveyor belts disposed in parallel, and two parallel lifting conveyor belts 3 are disposed between the two tray stacking conveyor belts 2 in the tray stacking station 1, and are used for decelerating the seedling trays, and cooperate with the tray stacking mechanism 6 to stack the seedlings. In order to realize the exchange and carrying of the seedling trays between the tray stacking conveyor belt 2 and the lifting conveyor belt 3, the conveying surface of the lifting conveyor belt 3 is set to be higher than the conveying surface of the tray stacking conveyor belt 2, and the height difference h between the conveying surfaces is 0.5cm-2cm, so that the seedling trays can be stably transited between the tray stacking conveyor belt 2 and the lifting conveyor belt.

Before the seedling disc enters the disc stacking station 1, the seedling disc is conveyed by the high-speed disc stacking conveyor belt 2, when the seedling disc enters the disc stacking station 1, the seedling disc is transferred from the disc stacking conveyor belt 2 to the lifting conveyor belt 3 through the height difference between the disc stacking conveyor belt 2 and the lifting conveyor belt 3, the lifting conveyor belt 3 decelerates the seedling disc, the seedling disc is further stacked by matching with the disc stacking mechanism 6, after the seedling disc is sent out of the disc stacking station 1, the seedling disc is transferred from the lifting conveyor belt 3 to the disc stacking conveyor belt 2 at the rear section, and the disc stacking conveyor belt 2 conveys the seedling disc to a subsequent processing section at a high speed. Therefore, in the process of realizing automatic disc stacking, the disc stacking speed is greatly improved.

In the actual disc stacking process, the seedling discs are continuously conveyed in the lifting conveyor belt 3, and the front ends of the seedling discs are difficult to align when the seedling discs are circularly stacked, so that the disc stacking is not neat enough. Therefore, the utility model discloses set up blocking mechanism 4 in the rear end of lifting conveyer belt 3, be used for blockking the seedling dish, make it stop predetermineeing the position to when guaranteeing to fold the dish, the seedling dish is located same position.

When the seedling trays are conveyed on the tray-stacking conveying belt 2, the seedling trays cannot be stacked neatly when being stacked due to the fact that the widths of the seedling trays with different sizes are different from the width between two tray-stacking conveying belts. For this purpose, at least one centering structure 5 is respectively arranged on both sides of the front end of the tray-stacking conveyor 2 in the embodiment, so as to adjust the position of the seedling trays in the width direction of the tray-stacking conveyor 2.

Specifically, as shown in fig. 3, the centering structure 5 is a plate-shaped structural member detachably mounted on the rack, and has an inclined surface 501 and a guide surface 502 which are sequentially connected with each other and face the inner side surface of the tray stacking conveyor 2, wherein the inclined surface 501 is used for adjusting the inclination direction of the seedling trays to perform the function of correcting deviation, and the guide surface 502 is used for guiding, so that when a plurality of plate-shaped structural members are provided, the functions of correcting deviation and guiding the seedling trays can be performed more reliably.

In addition, in order to coordinate the structures in the tray stacking process, lifting control switches are arranged on two sides of the lifting conveyor belt 3 and are used for controlling the stacking of the seedling trays. The photoelectric correlation sensors are arranged on two sides of a conveying path of the lifting conveying belt 3, the height of each photoelectric correlation sensor is equal to that of a preset seedling tray continuously conveyed to the tray stacking station 1, when the preset position that the seedling tray is conveyed to the tray stacking station 1 is sensed, the tray stacking mechanism is controlled to stack the seedling trays, and when the seedling trays in the tray stacking station reach the preset number, the stacked seedling trays are conveyed out of the tray stacking station 1. Meanwhile, a tray feeding control switch which can be a contact switch is arranged at the front end of the tray stacking conveyor belt 2 and is matched with the lifting control switch, and after the stacked seedling trays which are stacked in the tray placing station 1 are sent out, the tray stacking conveyor belt 2 is controlled to continuously convey the seedling trays to the lifting conveyor belt 3.
