The present invention relates to a medicine packaging machine, and in particular to a mechanism for automatically placing a pad inside a carton.
Cardboard boxes on pharmaceutical packaging lines need to be placed in cardboard as auxiliary items to make the box stronger. Manually adding pads is time-consuming, labor-intensive, and inefficient, and cannot meet production requirements.
Technical realization elements:
An object of the present invention is to provide a mechanism for automatically placing a pad in a carton box in view of the shortcomings of the prior art.
The object of the present invention is achieved by the following technical means:
Including controller, rack, transmission assembly at the lower part of the rack, backing plate slot and vacuum gripping assembly at the top of the rack, position sensors and positioning telescopic cylinders are provided on one side of the transmission assembly, and the backing plate slot and vacuum gripping assembly are set separately Above the two ends of the transmission component, the backing plate slot is open to one side of the vacuum gripping component, and spring hinges are provided on the two side walls. The vacuum gripping component is installed on the frame by rotating the component, the position sensor, the positioning telescopic cylinder, The rotating and vacuum gripping components are connected to the controller.
In a preferred solution, a slide rail is provided below the pad groove, and a balancer is provided on the slide rail, and the slide rail is fixed on the slide rail by bolts.
In a preferred solution, the rotating component is a rotating cylinder.
In a preferred solution, the vacuum gripping assembly includes a support, a moving plate, a cylinder, a suction cup, and a vacuum generator. The cylinder body is fixed on the support, the telescopic rod of the cylinder is fixed on the moving plate, the moving plate has a guide post, and the support has a guide sleeve. The guide column slides in the guide sleeve, there is a suction cup on the moving plate, and the suction cup is connected to a vacuum generator.
Compared with the prior art, the present invention has the following obvious advantages: the controller controls the components to work together, and the vacuum gripping component continuously sucks the cushion plate in the cushion plate slot and puts it in a carton on the transmission component. high working efficiency.
BRIEF DESCRIPTION OF THE DRAWINGS
Fig. 1 is a front perspective view of the present invention; Fig. 2 is an enlarged view at a in Fig. 1; Fig. 3 is an enlarged view at b in Fig. 1; Fig. 4 is an enlarged view at c in Fig. 1; Rear perspective view.
The following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments. In the figure, 1 frame, 101 columns, 102 beams, 103 beams, 2 roller conveyor belt, 301 support, 302 cylinder, 303 guide column, 304 Guide sleeve, 305 moving plate, 306 suction cup, 4 pad plate slot, 401 spring hinge, 402 balancer, 5 pad plate, 6 carton, 7 baffle plate, 8 rotary cylinder.
For the convenience of description, the outward orientation in FIG. 1 is taken as the front and the inward orientation is taken as the rear. As shown in the figure, the utility model includes a controller, a frame 1, a roller conveyor belt at the lower portion of the frame 1, a backing plate slot 4 at the upper portion of the frame 1, and a vacuum gripping assembly.
The frame 1 is composed of a combination of two I-shaped support frames. The I-shaped support frame includes two columns 101 and a beam 102. The I-shaped support frames are fixed by two beams 103 and the rollers are fixed between the I-shaped support frames. Conveyor belt 2, roller conveyor belt 2 is provided with baffles 7 on the front and rear sides to limit the position of the carton 6, and position sensors and positioning cylinders are provided on the rear side. The position sensor detects the carton 6 transmitted by the roller conveyor belt 2. The signal is transmitted to the controller. The controller controls the positioning cylinder to extend the cylinder rod and block the carton 6. This position is the working position of the pad 5.
The top left side of the roller conveyor belt 2 is a backing plate slot 4, the backing plate slot 4 is fixed on the frame 1, the bottom plate is inclined to the lower right, the right side of the backing plate slot 4 is open, and two springs are provided on each side wall. Page 401, the pad 5 is vertically placed in the pad 4 and is blocked by a spring hinge to prevent the pad 4 from slipping out. There is a slide rail under the pad 4 and a balancer 402 on the slide rail. Bolts are fixed on the slide rails to stabilize the backing plate groove 4.
Above the roller conveyor belt 2 there is a vacuum gripping assembly connected to the frame 1 through a rotating cylinder 8 including a support 301, a moving plate 305, a cylinder 302, a suction cup 306, and a vacuum generator. One end of the main body of the cylinder 302 is fixed to the support. On 301, to stabilize the cylinder 302, the support 301 is connected to the fixed plate 307, the other end of the main body of the cylinder 302 is fixed on the fixed plate 307, the telescopic rod of the cylinder 302 is fixed on the moving plate 305, and there are two guide posts 303 on the moving plate 305 to support There are two guide sleeves 304 on 301, the guide post 305 slides in the guide sleeve 304, there are four suction cups 306 on the moving plate 305, and the suction cups 306 are connected to a vacuum generator.
In the initial position of the vacuum gripping assembly, the suction plate 306 is directed toward the backing plate 5. The controller controls the cylinder 302 to extend, which drives the moving plate 305 to move to the left. The suction cup 306 generates negative pressure, sucks the pad 5 and the controller controls the cylinder 302 to contract. It takes the pad 5 to move to the right and the spring hinge 401 opens. After taking out a pad 5 the spring hinge 401 closes and the controller controls The rotary cylinder 8 rotates downward, and the front end of the vacuum gripping component 3 rotates 90 degrees downward. The pad 5 enters the carton 6 to stop the operation of the vacuum generator. The suction plate 306 releases the pad 5 and the controller controls the rotary cylinder 8 to rotate upward. After returning to the initial position, the positioning cylinder contracts, and the carton 6 moves to the right.
