Detailed Description

As shown in fig. 1-2, an automatic box holding and turning mechanism comprises a frame 1, and a turning mechanism 2 and a clamping mechanism 3 are mounted on the frame 1. The clamping mechanism 3 is used for clamping the box body 4, and the turnover mechanism 2 is used for driving the box body 4 to turn over.

As shown in fig. 3, the turnover mechanism 2 includes a turnover shaft 2.1, the turnover shaft 2.1 is formed by connecting three parts, a transmission shaft, a connection shaft and a driven shaft from left to right, the transmission shaft, the connection shaft and the driven shaft are clamped by U-shaped rabbets, and are fixed firmly by bolt assemblies. Two ends of the overturning shaft 2.1 are assembled and connected with the frame 1 through UCP bearings and bolt assemblies. The left and right sides of the turnover shaft 2.1 are fixedly provided with turnover arms 2.3, the outer side of the turnover shaft 2.1 is provided with a gear rack mechanism 2.2 for driving the turnover shaft 2.1 to rotate, and the gear rack mechanism 2.2 drives the turnover shaft 2.1 to rotate around the axis of the turnover shaft.

As shown in fig. 4, the rack and pinion mechanism 2.2 comprises a gear 2.2.1, the gear 2.2.1 is mounted on the roll-over shaft 2.1 and the edge is engaged with the rack 2.2.2. One side of the rack 2.2.2 is arranged on the guide rail 2.2.3 in a sliding way and driven to move up and down through the lifting cylinder 2.2.4.

The gear 2.2.1 and the rack 2.2.2 have good impact resistance and bear large torque, and have the performance of quick start and stop.

Preferably, proximity switches 5 are installed on the upper and lower portions of the rack 1, a photoelectric switch 6 is installed on the other side of the rack 1, and the proximity switches 5 and the photoelectric switch 6 are electrically connected with the PLC control system through cables. The two groups of proximity switches 5 can effectively control the overturning angle of the overturning mechanism 2 between 0 and 180 degrees. The photoelectric switch 6 is used for detecting whether the box body 4 is in place.

The turnover mechanism 2 is mainly realized by converting the reciprocating linear motion of the rack 2.2.2 into the rotary motion of the gear 2.2.1. The turnover mechanism 2 drives the rack 2.2.2 to reciprocate up and down by utilizing the lifting cylinder 2.2.4, so that the rack 2.2.2 drives the gear 2.2.1 to perform rotary motion, thereby driving the turnover shaft 2.1 and the turnover arm 2.3 to rotate, and thus, the turnover operation of the box body 4 can be realized.

As shown in fig. 5, the clamping mechanism 3 includes two groups of clamping cylinders 3.1, and the clamping cylinders 3.1 are transversely arranged at the ends of the turnover arm 2.3. The piston rod of the clamping cylinder 3.1 is fixedly connected with the mounting seat 3.2 through a bolt component, the clamping clamp 3.3 is fixed on the mounting seat 3.2, and the left clamping clamp 3.3 and the right clamping clamp 3.3 clamp the box body 4.

Preferably, the canvas rubber sheet 3.3.2 is mounted inside the clamping clip 3.3, and the canvas rubber sheet 3.3.2 can provide a large friction force.

Preferably, the edge of the clamping clip 3.3 is provided with a rib 3.3.3. The flange 3.3.3 can effectively prevent the medical waste special box from falling off.

Preferably, a waist-shaped hole 3.3.1 is formed in the clamping clamp 3.3, a positioning hole is formed in the corresponding mounting seat 3.2, and the bolt assembly penetrates through the positioning hole in the mounting seat 3.2 and the waist-shaped hole 3.3.1 in the clamping clamp 3.3 and then is locked. The clamping of various types of boxes 4 can be met because the mounting angle of the clamping clamp 3.3 is adjustable.

Clamping mechanism can press from both sides box 4 (special case of medical waste) tightly, mainly utilize two transversely arranged die clamping cylinder 3.1 to drive the die clamping 3.3 when the piston rod extends and to produce positive pressure to box 4, because the canvas rubber slab 3.3.2 on the die clamping 3.3 is surperficial rough, under die clamping cylinder 3.1's positive pressure effect, canvas rubber slab 3.3.2 produces ascending frictional force to box 4, when the ascending frictional force that produces is greater than box 4 because the decurrent gravity that the dead weight produced, box 4 just can firmly be pressed from both sides tightly by clamping mechanism 3 and do not drop.

In addition, the device also controls the speed of air inlet and outlet by utilizing a speed regulating valve in the air pressure system so as to control the telescopic speed of a piston rod of the lifting cylinder 2.2.4, and the overturning speed of the overturning mechanism 2 can be adjusted.

In addition, the device also utilizes a pressure regulating valve in the air pressure system to regulate the clamping force of the clamping cylinder 3.1, thereby avoiding the box body 4 from being broken by too large clamping force; also can avoid leading to the upset in-process box 4 to drop because the clamp force is not enough and can not press from both sides box 4 tightly to lead to the operation of can not normally turning over the case and pouring.

The working principle and the process are as follows: during operation, at first detect by photoelectric switch 6 after having the special case of medical waste, electric cabinet 8 starts die clamping cylinder 3.1 extension and drives die clamping 3.3 and press from both sides the special case of medical waste tightly, then starts lift cylinder 2.2.4 and drives rack 2.2.2 and rise in guide rail 2.2.3, rack 2.2.2 drives gear 2.2.1 and rotates, thereby gear 2.2.1 drives tilting mechanism 2 and rotates, after overturning to the settlement angle, upset arm 2.3 stops the upset, dangerous waste in the special case of medical waste will fall into the turnover case. Then PLC control system control lift cylinder 2.2.4 drive rack 2.2.2 descends in guide rail 2.2.3, rack 2.2.2 drives gear 2.2.1 and carries out the reverse rotation, thereby gear 2.2.1 drives tilting mechanism 2 and carries out the reverse rotation, upset arm 2.3 stops the upset when initial position, then start die clamping cylinder 3.1 and withdraw, die clamping clamp 3.3 and the special case of medical waste separate, the special case of medical waste is taken away to the manual work, at this moment, the special case of medical waste turns over the case and expects the work and just finishes.
