Background
Blister packs machines are devices for loading blister cards (e.g. capsule tablets) with paper instructions into packs, and the pack bundling devices are used for subsequent packaging in blister packs machines, in particular for bundling packs arranged in one or more rows by means of plastic film. The general working principle of the medicine box bundling device is as follows: the medicine boxes from the blister boxing machine firstly enter a box stacking mechanism of box bundling equipment, when the medicine boxes are stacked into a set row number, all the stacked medicine boxes are pushed to a front station by a material pushing mechanism, and then the bundling work of the medicine boxes is completed by a plurality of front working procedures. With the updating of the technology and the increase of the demand of users, the speed and the yield of the front-end blister boxing unit are continuously improved, the previous bundling machine type cannot meet the requirement of front-end equipment, the production bottleneck is formed, and the improvement of the yield of the whole production line is limited. One of the important factors is that the back and forth movement of the pushing mechanism of the previous bundling machine type is horizontal operation, when the pushing mechanism pushes out stacked multiple rows of medicine boxes, the box stacking mechanism cannot work, and the box stacking mechanism can continue to work only after the pushing mechanism returns, so that the speed of the whole machine is prevented from being increased.

Detailed Description
As shown in fig. 1, the circular track pushing mechanism is a mechanism of a medicine box bundling apparatus, and includes a pushing plate 1, a horizontal sliding seat 2, a horizontal guide rail 6 and a power source 6, the horizontal sliding seat 2 is slidably disposed on the horizontal guide rail 5, the pushing plate 1 is disposed on the horizontal sliding seat 2, the horizontal sliding seat 2 moves by being driven by the power source 6, the pushing plate 1 pushes the medicine box to advance, and the combination of the power source 6 and the horizontal guide rail 5 can be an electric cylinder, which is a prior art.
In order to enable the material pushing plate 1 to move along an annular track, the horizontal sliding seat 2 of the utility model is provided with a vertical sliding seat 4, and the material pushing plate 1 is arranged on the vertical sliding seat 4 in a sliding way through a vertical guide rail 3 (the material pushing plate 1 is connected on the vertical guide rail 3, and the vertical guide rail 3 is arranged on the vertical sliding seat 4 in a sliding way); a vertical guide groove plate 8 is arranged on one side of the horizontal guide rail 5, an annular guide groove 80 is arranged on the guide groove plate 8, an extension guide groove 81 extending forwards is arranged on the lower section of the annular guide groove 80 (the extension guide groove 81 is communicated with the lower section of the annular guide groove 80 and is positioned on the same straight line), an ascending section 801 is arranged on the upper section of the annular guide groove 81, and the ascending section 801 of the annular guide groove 80 is communicated with the extension guide groove 81; the vertical guide rail 3 is provided with a guide wheel 30, and the guide wheel 30 is positioned in the annular guide groove 80; further, a one-way stopper 9 is hinged to the chute plate 8, and the swing of the one-way stopper 9 has a first state in which the guide roller 30 enters the extended guide groove 81 from the lower section of the endless guide groove 80 and a second state in which the guide roller 30 is restricted from entering the lower section of the endless guide groove 80 from the extended guide groove 81 and the guide roller 30 enters the upper section of the endless guide groove 80.
The working principle is as follows: as shown in fig. 1, when pushing is needed, the power source 6 drives the horizontal sliding base 2 to move forward on the horizontal guide rail 5, so that the pushing plate 1 pushes the medicine box to move forward, as shown in fig. 3, since the one-way stopper 9 has a first state that allows the guide wheel 30 to enter the extending section guide groove 81 from the lower section of the annular guide groove 80 (i.e. the one-way stopper 9 swings upward), so that the pushing plate 1 moves to the forefront to complete the pushing work, and at this time, the guide wheel 30 is in the extending section guide groove 81, then the power source 6 drives the horizontal sliding base 2 to move back on the horizontal guide rail 5, since the second state that restricts the guide wheel 30 from entering the lower section of the annular guide groove 80 from the extending section guide groove 81 and allows the guide wheel 30 to enter the upper section of the annular guide groove 80 (i.e. the one-way stopper 9 swings downward under the action of its own gravity to reset, the one, therefore, the guide wheel 30 can only move upwards along the climbing section 801 of the annular guide groove 80 and reaches the upper section of the annular guide groove 80, the vertical guide rail 3 moves upwards on the vertical sliding seat 4, the material pushing plate 1 rises and returns, and even if the material pushing plate 1 is lifted, the working space of the box stacking mechanism cannot be interfered in the return process of the material pushing plate 1, so that the box stacking mechanism can continuously run, and the speed of the whole machine is increased.
Since the vertical guide 3 passes in front of the one-way stopper 9, the two stops will certainly interfere with each other if they are in the same plane, and therefore the one-way stopper 9 is positioned inwardly with respect to the vertical guide 3. For this reason, as shown in fig. 3, a swing groove 82 for swinging the one-way stopper 9 is provided at the intersection of the extended section guide groove 81 of the guide groove plate 8 and the annular guide groove 80, the depth of the swing groove 82 is shallower than that of the annular guide groove 80, and the one-way stopper 9 is located in the swing groove 82, by which the path of the annular guide groove 80 is not affected while the one-way stopper 9 is located in the swing groove 82, avoiding the vertical guide rail 3.
In order to make the guide wheel 30 move from the extended section guide groove 81 to the upper section of the circular guide groove 80 more smoothly, as shown in fig. 3, the upper surface of the one-way stopper 9 has a straight edge 90 parallel to the rising section 801 of the circular guide groove and a curved edge 91 joining the rising section 801 of the circular guide groove and the extended section guide groove 81. As guide wheel 30 transitions from extension channel 81 to annular channel ramp 801, it moves along arcuate edge 91 of one-way stop 9 and then along linear edge 90 of one-way stop 9 into annular channel ramp 801.
Because only one guide pulley 30 in vertical guide 3 upper portion is in annular guide slot 80, that is to say vertical guide 3 only receives the support this point, vertical guide 3 moves and probably is not stable enough, in order to solve this problem, as shown in fig. 2, the utility model discloses be connected with extension spring 7 on horizontal sliding seat 2, this extension spring 7 is located the rear side of guide slot board 8, and the upper end of vertical guide 3 is being pulled to the upper end of extension spring 7. The tension spring 7 is used for pulling, the lower end and the upper end of the vertical guide rail 3 are stressed, so that the vertical guide rail 3 can keep balance, and the operation is more stable.
