Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1-2, the pallet stacking device provided by the present invention adopts a dual-drive sprocket structure, a pair of elastic friction limiters 2 are respectively disposed on two sides of each drive sprocket 1, specifically, the drive sprocket 1 is driven by a motor to drive a drive chain 3.
The elastic friction limiter 2 is a key core component of the device. In particular, the elastic friction limiter 2 is fixed on the tray 5 by means of a mounting 4.
As shown in fig. 2, the elastic friction restrictor 2 includes a restrictor body 6, a friction block 7, an adjustment screw 8, and a spring 9.
The friction block 7 is positioned at one end of the limiter body 6 close to the driving chain wheel 1, and the friction block 7 is made of wear-resistant materials. Specifically, the friction block 7 is made of ceramic fiber materials, so that the service life is long, and the replacement is convenient.
The spring 9 is positioned in the limiter body 6, one end of the spring is pressed against the friction block 7, and the other end of the spring is sleeved on the adjusting screw rod 8. The adjusting screw 8 is in threaded connection with one end, far away from the driving chain wheel 1, of the limiter body 6, and the adjusting screw 8 is used for adjusting the compression length of the spring 9 to change the friction force on the driving chain wheel 1.
The device adopts a dual-drive chain wheel structure, and a pair of elastic friction limiters are arranged on two sides of each drive chain wheel. The working principle is as follows:
the chain conveyor line tray driving device is characterized in that a traction force F of a chain driven by a motor is used, a resistance force F (the sum of a friction force F1 between a guide wheel and a track and a tray stopping force F2 when a tray runs, and F2 is 0 when the tray is not stopped) is generated when the tray runs, and a static friction force F3 of an elastic friction limiter is applied to a driving chain wheel.
When F is less than or equal to F3, the two driving chain wheels are in a rotation stopping state, and the tray can move forward under the action of chain traction force F;
when the pallet is stopped, F is larger than F3, the two driving chain wheels rotate under the action of chain traction force F, and the pallet stops advancing.
When the subsequent trays arrive successively and are blocked by the previous stopping tray, the driving chain wheels are completely changed from the rotation stopping state to the rotation state to stop the trays, so that the stacking function of the trays is realized.
Furthermore, to improve stability, guide wheels 10 are connected to both sides of the driving sprocket through a transmission shaft. For further stability, two guide wheels 10 located on the same side are fixed by a connecting plate 11.
The tray stacking device provided by the utility model can be applied to a vertical rotary chain conveying line and a horizontal rotary chain conveying line, and is simple in structure, low in manufacturing cost and convenient to install and maintain.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: it is to be understood that modifications may be made to the technical solutions described in the foregoing embodiments, or equivalents may be substituted for some of the technical features thereof, but such modifications or substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
