An automatic loading and unloading device and method for a filter rod transmitter

Abstract

The present invention discloses an automatic loading and unloading device and method for a filter rod transmitter. The rectangular box is sent to one side of the loading mechanism through a feeding belt. The front and rear end faces of the rectangular box are clamped by a clamp in the loading mechanism. After the clamp clamps the rectangular box, the rectangular box is lifted by a loading chain. When the rectangular box is lifted below the baffle mechanism, the baffle cylinder in the baffle mechanism drives the baffle to extend and cover the upper end face of the rectangular box. The baffle mechanism and the loading mechanism move synchronously, so that the rectangular box with the baffle covered is flipped 180° on the loading mechanism. The baffle cylinder drives the baffle to withdraw, realizing the blanking of the cigarette filter rods in the rectangular box. During the blanking process of the cigarette filter rods, the unloading clamping plate in the unloading mechanism clamps the rectangular box, and the loading mechanism and the baffle mechanism both return to the initial positions. The feeding belt sends the next rectangular box filled with cigarette filter rods to one side of the loading mechanism, and so on. The present invention is an automatic loading and unloading device for a filter rod transmitter with a simple structure, convenient maintenance and low manufacturing cost.

[0032] The loading mechanism 1 includes a loading rack 11, loading chains 12, sliders 13 and a fixture 14. Four sprockets are rotatably connected to the loading rack 11. The four sprockets are divided into two groups in pairs, and the two sprockets in each group are fixed by a rotating shaft. Two loading chains 12 are rotatably connected to the sprockets on the loading rack 11 in parallel, and the loading chains 12 are arranged on the loading rack 11. A motor is provided on the loading rack 11 to drive the sprockets to rotate. Two sliders 13 are slidably connected to the loading rack 11, and the two sliders 13 are correspondingly connected to the two loading chains 12. Both ends of the fixture 14 are fixedly connected to the two sliders 13.

[0033] To achieve more stable sliding of the slider 13 on the loading rack 11, a pulley 131 is provided on the slider 13, and a chute 111 is provided on the loading rack 11. The pulley 131 is slidably connected in the chute 111.

[0034] The loading chain 12 can drive the slider 13 to move cyclically on the loading rack 11. To achieve the cyclic movement of the slider 13, the chute 111 on the loading rack 11 is annular, and the fixture 14 can move cyclically on the two driving sides of each loading chain 12.

[0035] The fixture 14 in the present invention includes a second mounting plate 141, a slide rail 142, a slide seat 143, clamping arms 144 and a clamping arm cylinder 145. The slide rail 142 and the two clamping arm cylinders 145 are both fixedly connected to the second mounting plate 141. The two clamping arm cylinders 145 drive the two slide seats 143 to slide on the slide rail 142, and the two clamping arms 144 are correspondingly fixedly connected to the two slide seats 143. The moving directions of the two clamping arms 144 are perpendicular to the moving direction of the loading chain 12.

[0036] The baffle mechanism 2 in the present invention includes a baffle chain 21, a first mounting plate 22, a baffle 23 and a baffle cylinder. Two baffle chains 21 are placed inside two feeding chains 12 and are parallel to the feeding chains 12. The two ends of the first mounting plate 22 are mounted on the two baffle chains 21. The baffle 23 is inserted into the first mounting plate 22. The baffle cylinder is fixedly connected to the first mounting plate 22, and the cylinder shaft of the baffle cylinder is fixedly connected to the baffle 23.

[0037] The discharging mechanism 3 includes a discharging chain 31, a mounting block 32, a guide rail 33, a discharging cylinder 34 and a discharging clamping plate 35. Two discharging chains 31 are arranged outside the feeding chain 12. A guide rail 33 is arranged on one side of each discharging chain 31. Two mounting blocks 32 are slidably connected to the two guide rails 33, and the two mounting blocks 32 are correspondingly connected to the two discharging chains 31. Two discharging cylinders 34 are mounted on the two mounting blocks 32, and the cylinder shaft of each discharging cylinder 34 fixes a discharging clamping plate 35.

[0038] Wherein, the discharging chain 31 includes an inclined portion and a horizontal portion. The inclined portion is parallel to the feeding chain 12, and the horizontal portion is arranged above the feeding rack 11.

[0039] A conveyor belt mechanism 4 is arranged on one side of the feeding mechanism 1. The conveyor belt mechanism 4 includes a feeding belt 41 and a limiting frame 42. Two limiting frames 42 are arranged in parallel above the feeding belt 41, thereby realizing the automatic feeding of the filter rods.

[0040] Combined with the structure of the present invention, the following description is made for the feeding and discharging process of the present invention:

[0041] 1) Place the cigarette filter rods in a rectangular box 500 with both the upper end face and the right end face open. Place the rectangular box 500 on the feeding belt 41, and make the bottom surface of the rectangular box 500 contact the feeding belt 41. Send the rectangular box 500 to one side of the feeding mechanism 1 through the feeding belt 41.

[0042] 2) Clamp the front and rear end faces of the rectangular box 500 through the clamp 14 in the feeding mechanism 1. After the clamp 14 clamps the rectangular box 500, lift the rectangular box 500 through the feeding chain 12. When the rectangular box 500 is lifted below the baffle mechanism 2 and is sensed by the proximity switch, at this time the feeding chain 12 stops moving, and then the baffle cylinder in the baffle mechanism 2 drives the baffle 23 to extend and cover the upper end face of the rectangular box 500.

[0043] 3) After it is sensed by another proximity switch that the baffle 23 covers the upper end face of the rectangular box 500, at this time the baffle mechanism 2 and the feeding mechanism 1 move synchronously, so that the rectangular box 500 with the baffle 23 covered is flipped 180° on the feeding mechanism 1, that is Figure 1The middle rectangular box 500 moves from the right side to the left side of the loading chain 12. After the rectangular box 500 moves to the unloading position and is sensed by the proximity switch for unloading, the loading chain 12 stops moving, and then the baffle cylinder drives the baffle 23 to be withdrawn. At this time, the cigarette filter rods in the rectangular box 500 start to fall.

[0044] 4) During the process of the cigarette filter rods falling, the unloading clamping plate 35 in the unloading mechanism 3 clamps the rectangular box 500, and then the fixture 14 in the loading mechanism 1 releases the rectangular box 500. Both the loading mechanism 1 and the baffle mechanism 2 return to the initial positions. The unloading mechanism 3 clamps away the empty rectangular box 500 that has unloaded the filter rods. A unloading belt is arranged below the horizontal part of the unloading chain 31 in the unloading mechanism 3. The unloading mechanism 3 sends the empty rectangular box 500 to the unloading belt. The feeding belt 41 sends the next rectangular box 500 filled with cigarette filter rods to one side of the loading mechanism 1, and then the process of steps 1)-4) is repeated.

[0045] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
