Description

Technical Field

[0001] The utility model relates to a blister plate cartoning machine, in particular to a double-track annular material pushing guide rail and a cartoning machine material pushing device using the guide rail. Background Art

[0002] The blister plate cartoning machine is a device that loads blister plates (such as capsule medicine plates) and paper instructions into medicine boxes. For example, the applicant applied for an invention patent in 2019 entitled "A rapidly adjustable blister cartoning machine pushing device" (CN2019113701962). The existing annular paper push guide and annular plate push guide are two completely independent mechanisms. Specifically, a guide groove frame is provided on the periphery of the annular plate push guide, and the annular paper push guide is located on the guide groove frame. Obviously, this structure is more complicated due to separate control, and the program control is more troublesome. Most importantly, the entire device appears larger. In order to solve this problem, the applicant applied for an invention patent in 2020 entitled "Annular Push Guide and a Cartoning Machine Pushing Device Using the Guide" (CN112478268A). This annular pusher guide includes a pusher track changing assembly, which includes a track changing fork and a track changing power source for driving the track changing fork to rotate. The track changing fork is arranged in a running guide groove, and one end of the running guide groove branches out into a straight protection guide groove, a first oblique pusher guide groove and a second oblique pusher guide groove. The entrance of the straight protection guide groove, the entrance of the first oblique pusher guide groove and the entrance of the second oblique pusher guide groove are all located in front of the track changing fork. It can be seen that this annular pusher guide integrates the paper pushing guide function and the push plate guide function, and also has a paper pushing protection function and a push plate protection function. However, this annular pusher guide has only one running guide groove, and the push plate roller and the paper pushing roller both run in the running guide groove, and the front end branch of the running guide groove has four guide grooves. When the push plate roller and the paper pushing roller transition at the branch, it is easy to collide with the end of the branch guide groove, or even get stuck, resulting in a malfunction.

[0022] like Figure 1 As shown, the pushing device of the blister cartoning machine includes a plurality of pushing units B, a double-track annular pushing guide rail A and a traction mechanism C; the plurality of pushing units B are driven by the traction mechanism C and guided by the double-track annular pushing guide rail A to push the instruction sheet P and the medicine plate M into the medicine box. Figure 6 As shown, the pushing unit B includes a pushing seat B0, a pushing plate assembly and a paper pushing assembly. The paper pushing assembly includes a paper pushing head B10 and a paper pushing roller B1; the pushing plate assembly includes a pushing plate head B20 and a pushing plate roller B2. The double-track annular pushing guide A guides the paper pushing roller B1 and the pushing plate roller B2 of the pushing unit B, allowing the paper pushing head B10 and the pushing plate head B20 to push the material forward.

[0023] like Figure 2 and Figure 3 As shown, the double-track annular pusher guide rail A includes an annular main body A0 (racetrack shape), on which a first running guide groove 1 and a second running guide groove 2 are arranged side by side. Figure 7 As shown, the depth of the first walking guide groove 1 is less than the depth of the second walking guide groove 2 (the "depth" mentioned in this application refers to the height of the bottom surface of the guide groove. If the bottom surface of the guide groove is low, it means that the depth is deep, and if the bottom surface of the guide groove is high, it means that the depth is shallow); as shown in FIG. Figure 2 and Figure 3 As shown, a first oblique material pushing guide groove 10 and a first straight protection guide groove 11 are branched out at the head end of the first running guide groove 1, and the first oblique material pushing guide groove 10 and the first straight protection guide groove 11 merge at the tail end (not shown) of the first running guide groove 1, and the depth of the first oblique material pushing guide groove 10 and the depth of the first straight protection guide groove 11 are the same as the depth of the first running guide groove 1. The paper pushing roller B1 is located in the first running guide groove 1, so that the paper pushing roller B1 can enter the first oblique material pushing guide groove 10 (to push the material), and can also enter the first straight protection guide groove 11 (not to push the material).

[0024] The head end of the second walking guide groove 2 branches out a second oblique pushing guide groove 20 and a second straight protection guide groove 21, and the second oblique pushing guide groove 20 and the second straight protection guide groove 21 merge at the tail end of the second walking guide groove 2, and the depth of the second oblique pushing guide groove 20 and the depth of the second straight protection guide groove 21 are the same as the depth of the second walking guide groove 2; since the second oblique pushing guide groove 20 must maintain the same inclination as the first oblique pushing guide groove 10 (the inclination allows the roller to move obliquely to achieve pushing), the first straight protection guide groove 11 and the second oblique pushing guide groove 20 have an intersection; the push plate roller B2 is located in the second walking guide groove 2, so that the push plate roller B2 can enter the second oblique pushing guide groove 20 (to achieve pushing), and can also enter the second straight protection guide groove 21 (not pushing); since the depths of the first straight protection guide groove 11 and the second oblique pushing guide groove 20 are different, such as Figure 8 As shown, the position of the push plate roller B2 is lower than that of the paper push roller B1, so that at the intersection of the first straight protection guide groove 11 and the second oblique material pushing guide groove 20, since the paper push roller B1 is at a higher position, the paper push roller B1 can cross the second oblique material pushing guide groove 20 and only move in the first straight protection guide groove 11, while the push plate roller B2 is at a lower position, so the push plate roller B2 can only move in the second oblique material pushing guide groove 20. In this way, it can be ensured that the paper push roller B1 and the push plate roller B2 will not go wrong at the intersection of the guide grooves.

[0025] With the above structure, the paper pushing roller B1 and the plate pushing roller B2 respectively run in their own guide grooves and are guided by the guide grooves at each position, so the operation is more stable and no collision occurs due to switching of the guide grooves.

[0026] In order to make the paper pushing roller B1 and the push plate roller B2 change tracks at the same time, a rotatable first track changing guide groove 14 is provided at the head end branch of the first running guide groove 1, and a rotatable second track changing guide groove 24 is provided at the head end branch of the second running guide groove 2. The first track changing guide groove 14 and the second track changing guide groove 24 are both connected to the track changing power source 8 by transmission; when the track changing power source 8 drives the first track changing guide groove 14 and the second track changing guide groove 24 to rotate to the pushing direction together, the first track changing guide groove 14 connects the first running guide groove 1 with the first oblique pushing guide groove 10, so that the paper pushing roller B1 transitions from the first running guide groove 1 to the first oblique pushing guide groove 10; the second track changing guide groove 24 connects the second walking guide groove 2 with the second oblique pushing guide groove 20, so that the push plate roller B2 transitions from the second walking guide groove 2 to the second oblique pushing guide groove 20; when the track changing power source 8 drives the first track changing guide groove 14 and the second track changing guide groove 24 to rotate to the protection direction together, at this time, the first track changing guide groove 14 connects the first walking guide groove 1 with the first straight protection guide groove 11, so that the paper pushing roller B1 transitions from the first walking guide groove 1 to the first straight protection guide groove 11; the second track changing guide groove 24 connects the second walking guide groove 2 with the second straight protection guide groove 21, so that the push plate roller B2 transitions from the second walking guide groove 2 to the second straight protection guide groove 21.

[0027] Sometimes the instruction manual or medicine board is stuck, causing the push plate assembly or paper push assembly to be resisted in the opposite direction, which may cause damage to the push plate assembly or paper push assembly. Figure 3 As shown, a first protective baffle 13 is provided on the path of the first oblique pushing guide groove 10, and the first protective baffle 13 forms a side wall of the first oblique pushing guide groove 10. One end of the first protective baffle 13 can be rotatably set, and the first protective baffle 13 can be turned to the side opposite to the pushing direction; similarly, a second protective baffle 23 is provided on the path of the second oblique pushing guide groove 20, and the second protective baffle 23 forms a side wall of the second oblique pushing guide groove 20. One end of the second protective baffle 23 can be rotatably set, and the second protective baffle 23 can be turned to the side opposite to the pushing direction; both the first protective baffle 13 and the second protective baffle 23 can be reset under the action of the elastic member. When the push plate assembly or the paper push assembly is subjected to resistance in the reverse direction, the paper push roller B1 reacts on the first protection baffle 13 in the first oblique material push guide groove 10, the first protection baffle 13 moves backward, and the paper push roller B1 also moves backward, so that the paper push assembly can move backward as a whole, and will not push the material forward hard, thereby playing a role in protecting the paper push assembly; similarly, the push plate roller B2 reacts on the second protection baffle 23 in the second oblique material push guide groove 20, the second protection baffle 23 moves backward, and the push plate roller B2 also moves backward, so that the push plate assembly can move backward as a whole, and will not push the material forward hard, thereby playing a role in protecting the push plate assembly. When everything is normal, the elastic member can drive the first protection baffle 13 and the second protection baffle 23 to reset.

[0028] In order to make the first protection barrier rod 13 and the second protection barrier rod 23 rotate synchronously, as shown in FIG. Figure 4 As shown, the first protection barrier rod 13 and the second protection barrier rod 23 are connected through a connecting rod 4, one end of the connecting rod 4 is hinged to the first protection barrier rod 13, and the other end of the connecting rod 4 is hinged to the second protection barrier rod 23. In this way, only one elastic member is needed to drive the two first protection barrier rods 13 and the second protection barrier rods 23 to reset at the same time, and the structure is simpler and more reasonable.

[0029] The elastic member can be a spring or a pusher protection cylinder 5. Figure 4 As shown, the telescopic rod of the push material protection cylinder 5 is hinged with the first protection blocking rod 13, the second protection blocking rod 23 or the connecting rod 4. The push material protection cylinder 5 can play the role of a spring.

[0030] When the instruction sheet or the medicine plate is completely stuck and cannot enter the paper box, it is necessary to stop the machine for inspection. For this purpose, a sensing sheet 9 is connected to the first protective baffle 13, the second protective baffle 23 or the connecting rod 4, and a protective photoelectric eye 90 is provided on the annular body A0. The protective photoelectric eye 90 can sense the position change of the sensing sheet 9. When the front end of the push head is blocked and the first protective baffle 13 and the second protective baffle 23 are rotated to the set position, the protective photoelectric eye 90 can sense the position change of the sensing sheet 9, thereby sending a signal to the control system, which controls the shutdown and alarms, and the equipment can only run after the obstacles in front are cleared and the normal indicators of the equipment are restored.

[0031] In order to drive the first track-changing guide groove 14 and the second track-changing guide groove 24 to rotate synchronously, as shown in FIG. Figure 5 As shown, one end of the first track change guide groove 14 is hinged on the track change support 7, the other end of the first track change guide groove 14 is hinged to the track change connecting rod 6, one end of the second track change guide groove 24 is hinged on the track change support 7, the other end of the second track change guide groove 24 is hinged to the track change connecting rod 6, and the track change power source 8 can drive the track change connecting rod 6 to move. Through this structure, the track change power source 8 drives the track change connecting rod 6 to rotate, which can drive the first track change guide groove 14 and the second track change guide groove 24 to rotate synchronously.

[0032] Finally, it is worth mentioning that the track change power source 8 is a motor, the output shaft 80 of the motor is connected to the transmission block 81, one end of the transmission block 81 is hinged to the transmission arm 82, and the other end of the transmission arm 82 is hinged to the track change connecting rod 6. Driven by the motor, the transmission block 81 rotates to drive the transmission arm 82 to rotate, thereby driving the track change connecting rod 6 to swing, so that the first track change guide groove 14 and the second track change guide groove 24 can achieve synchronous rotation. In the past, track change was controlled by a cylinder. Compared with cylinder track change, motor-driven track change has the advantages of faster speed, less noise, and less damage to parts.
