Description

Technical Field

[0001] The utility model relates to the field of bearing packaging, in particular to a bearing barrel loading and stacking mechanism. Background Art

[0002] After bearings need to be stacked, they can be fed into the packaging barrel body. The current operation method is to first stack the bearings using a stacking machine, and then put the stacked bearings into the packaging barrel body. For example, in the utility model patent with the authorization publication number CN216736335U and the authorization publication date of June 14, 2022, a bearing barrel loading and stacking mechanism is disclosed, which includes a stacking member, a second bottom plate, a first pushing component, a second pushing component, a first baffle, a first induction switch and a second induction switch; the bearings slide down from the guide rail and are blocked by the second baffle and stop. At this time, the second induction switch below the bearings senses the bearings, and the second pushing component receives the signal and acts once to push the bearings towards the first bottom plate. This process is repeated until the first row of bearings is full. When the first induction switch senses the bearings, the first pushing component receives the signal and acts once to push the first row of bearings into the groove of the first bottom plate. This stacking mechanism is not applicable to directly longitudinally inserting longitudinally stacked bearings into a longitudinally arranged packaging barrel body. Summary of the Utility Model

[0003] To overcome the above disadvantages, the purpose of the utility model is to provide a bearing barrel loading and stacking mechanism that can stack longitudinally and longitudinally insert longitudinally stacked bearings into the packaging barrel body.

The first lead screw sleeve 14 is threadedly connected to the first lead screw 13, and both ends of the first lead screw sleeve 14 are sleeved on the multiple guide posts 15 and can lift along the guide posts 15. The first lead screw sleeve 14 drives the material pushing member 6 to lift through a connecting rod; As Figure 3 shown in the figure, the material pushing member 6 is in an annular structure and is sleeved outside the stringing shaft 5. The first driving source drives the material pushing member 6 to lift through a connecting rod.

[0030] A receiving pipe 7 is located above the receiving plate 2, and multiple expansion slots 8 are opened on the side wall at the lower end of the receiving pipe 7;

[0031] A pulling rod 9 is located inside the receiving pipe 7, and a tapered head 10 is arranged at its lower end. The tapered head 10 is located at the lower end of the receiving pipe 7 provided with the expansion slots 8. The inner side wall at the lower end of the receiving pipe 7 in this embodiment is inclined and matches the shape of the tapered head 10;

[0032] A tensioning cylinder 11 drives the pulling rod 9 to lift. When the tapered head 10 rises, the tapered head 10 forces the lower end of the receiving pipe 7 to expand. The diameter formed by the expansion of the lower end of the receiving pipe 7 is larger than the inner diameter of the bearing;

[0033] The second driving source drives the lifting and translation of the material receiving pipe 7. The material receiving pipe 7 can move to directly above the material stringing shaft 5. The second driving source in this embodiment includes: a horizontal bracket 16, located on one side of the bearing conveyor belt 1, and a horizontal slide rail 17 is arranged on the horizontal bracket 16; a sliding frame 18, the back of the sliding frame 18 is slidably arranged on the horizontal slide rail 17, and a longitudinal slide rail 19 is arranged on the front of the sliding frame 18; a translation cylinder 20, fixed on the horizontal bracket 16 and acting to translate the sliding frame 18 along the horizontal slide rail 17; a second servo motor 21, fixed on the sliding frame 18, and its output shaft is connected with a second lead screw 22; a second lead screw sleeve 29, sleeved on the second lead screw 22 and in threaded cooperation with it, and one side of the second lead screw sleeve 29 is slidably arranged on the longitudinal slide rail 19; a connecting plate 23, fixed on one side of the second lead screw sleeve 29, and the material receiving pipe 7 and the tensioning cylinder 11 are fixed at the lower end of the connecting plate 23;

[0034] A turntable 24, multiple mounting grooves 25 are arranged on the turntable 24, and the mounting grooves 25 are used to store the packaging barrel bodies 26. The side of the turntable 24 close to the receiving plate 2 is the bearing loading position. An air gripper 27 is arranged at the bearing loading position to grip the packaging barrel body 26 at the bearing loading position. The air gripper 27 is driven by a third driving source to lift, as Figure 1 shown. The outer side of the mounting groove 25 in this embodiment is of an open structure, and a notch ring baffle 28 is arranged above the turntable 24, and the notch ring baffle 28 is located outside the turntable 24.

[0035] The working principle of this embodiment is as follows:

[0036] The bearings are horizontally conveyed one by one by the bearing conveyor belt 1 to one side of the receiving plate 2. The slot 3 of the receiving plate 2 is at the same height as the bearing conveyor belt 1. The dialing plate pushes the bearings on the bearing conveyor belt 1 into the slot 3 until they are located in the blanking hole 4. At this time, the upper surface of the ejector 6 is flush with the surface of the slot 3. The lower surface of the first bearing pushed into the blanking hole 4 is supported by the upper surface of the ejector 6. Then, the first servo motor 12 of the first driving source rotates, and the first lead screw 13 rotates accordingly. The first lead screw sleeve 14 moves down by the thickness of one bearing along the two guide posts 15. The first supported bearing moves down by the thickness of one bearing, that is, the upper surface of the first bearing is flush with the surface of the slot 3, so as to support the second bearing transferred to the blanking hole 4... and so on. The required number (such as eight) of bearings are all sleeved on the material stringing shaft 5.

[0037] The second driving source drives the material receiving pipe 7 to move directly above the stringing shaft 5. Then, the first servo motor 12 of the first driving source rotates in the reverse direction, and the material pushing member 6 moves upward until all eight bearings are sleeved on the material receiving pipe 7. The tensioning cylinder 11 drives the pull rod 9 to move upward, and the tapered head 10 causes the lower end of the material receiving pipe 7 provided with the tensioning grooves 8 to expand. The formed diameter is larger than the inner diameter of the bearing. The eight bearings are limited on the material receiving pipe 7. Then, it is moved upward by the second driving source and then translated (or directly translated) to above the packaging barrel body 26 at the bearing loading position of the turntable 24. Then, it moves downward, and the eight bearings are longitudinally inserted into the packaging barrel body 26. Then, the tensioning cylinder 11 drives the pull rod 9 to move downward, and the lower end of the originally expanded material receiving pipe 7 rebounds and resets. The formed diameter is smaller than the inner diameter of the bearing, and the eight bearings are no longer restricted by the material receiving pipe 7 and fall off from the material receiving pipe 7. The second driving source drives the material receiving pipe 7 to reset to receive the next batch of eight bearings.
