Description

Technical Field

[0001] The invention relates to the field of medicine packaging machinery, in particular to a medicine plate grid conveying device of a blister cartoning machine. Background Art

[0002] Blister cartoning machine is a mechanical device that loads blister plates (medicine plates) and instructions into cartons. Blister cartoning machine generally includes a pushing device, a medicine plate grid conveying device arranged side by side (because the medicine plate and the instructions are pushed into the carton together, it can also be called a material grid conveying device) and a box-moving device. The box-moving device is used to place cartons. As the box-moving device moves, the pushing device pushes the medicine plate and the instructions on the material grid conveying device into the carton together. The material grid conveying device includes a transmission shaft, a feeding sprocket, a feeding chain, a support and a grid plate. The grid plate is installed on the support, and the support is connected to the feeding chain. The feeding chain is wound around the feeding sprocket, and the feeding sprocket is installed on the transmission shaft. The transmission shaft is driven to rotate by the power source, and the feeding chain can carry the support and the grid plate to move in a cycle, and the material is placed on the support, and the grid plate plays a role of separation.

[0020] like Figure 1 As shown, this material grid conveying device is a grid ring structure, which is used to convey bubble cap plates. Figure 3 As shown, the material grid conveying device includes a transmission shaft 1, an active feeding sprocket 3 and a driven feeding sprocket 2, and an active feeding chain 37 is wound around the active feeding sprocket 3. Figure 2 As shown, the active feeding chain 37 is connected to a first support member 38, and the first support member 38 is provided with a first grid plate 39. The driven feeding sprocket 2 is wound with a driven feeding chain 27, and the driven feeding chain 27 is connected to a second support member 28, and the second support member 28 is provided with a second grid plate 29. The first grid plate 39 and the second grid plate 29 both have an extension portion extending to the other side; Figure 2As shown, when assembled, the first support member 38 and the second support member 28 are arranged side by side, and the first grid plate 39 extends to the position of the second support member 28, and the second grid plate 29 extends to the position of the first support member 38, so that two adjacent first grid plates 39 and second grid plates 29 are arranged side by side front and back; when the grid width needs to be adjusted, as long as the active feeding chain 37 remains stationary, the driven feeding chain 27 rotates, driving the second support member 28 and the second grid plate 29 to move, so that the distance between the second grid plate 29 and the first grid plate 39 changes, thereby meeting the placement requirements of bubble cap plates of different specifications. The adjustment transmission structure and the adjustment principle are specifically introduced below.

[0021] like Fig. 9 As shown, the active feeding sprocket 3 is connected to the transmission shaft 1, and the active feeding sprocket 3 is provided with an active transmission wheel 30 (the transmission wheel can be a sprocket or a pulley) whose diameter is smaller than that of the active feeding sprocket 3, and the driven feeding sprocket 2 is rotatably arranged on the transmission shaft 1, and the driven feeding sprocket 2 is provided with a feeding main adjusting wheel 20 (the adjusting wheel can be a sprocket or a pulley) whose diameter is smaller than that of the driven feeding sprocket 2; as shown in FIG. Figure 5-7 As shown, a driven shaft 5 is provided on one side of the transmission shaft 1, and the driven shaft 5 is rotatably mounted on the adjustment support 9, and a driven transmission wheel 31 and a feeding auxiliary adjustment wheel 21 are connected to the driven shaft 5, wherein a main transmission belt 32 (the transmission belt can be a chain or a synchronous belt) is wound around the driven transmission wheel 31 and the driving transmission wheel 30. When the transmission shaft 1 drives the driving transmission wheel 30 to rotate, the driving transmission wheel 30 can drive the driven transmission wheel 31 through the main transmission belt 32, thereby driving the driven shaft 5 to rotate.

[0022] like Figure 8 As shown, a feed adjustment plate 6 is installed on the adjustment support 9 so that it can be moved back and forth and adjusted. Two feed moving wheels 60 are installed on the feed adjustment plate 6. In addition, a feed auxiliary wheel 7 is also installed on the adjustment support 9. A feed transmission belt 22 is wound around the feed auxiliary wheel 7, the main feed adjustment wheel 20, the auxiliary feed adjustment wheel 21 and the two feed moving wheels 60. The mating surface between one feed moving wheel 60 and the feed transmission belt 22 is located on the left side of the feed moving wheel 60, and the mating surface between the other feed moving wheel 60 and the feed transmission belt 22 is located on the right side of the feed moving wheel 60.

[0023] When this material grid conveying device is working normally, the transmission principle is as follows: the motor drives the transmission shaft 1 to rotate, the transmission shaft 1 drives the active feeding sprocket 3 to rotate, and at the same time drives the active transmission wheel 30 to rotate, the active transmission wheel 30 drives the driven transmission wheel 31 through the main transmission belt 32, the driven transmission wheel 31 drives the driven shaft 5 to rotate, the driven shaft 5 drives the feeding auxiliary adjusting wheel 21, the feeding auxiliary adjusting wheel 21 rotates the feeding transmission belt 22, and the feeding transmission belt 22 rotates the feeding main adjusting wheel 20, because the feeding main adjusting wheel 20 is connected with the driven feeding sprocket 2, so that the driven feeding sprocket 2 rotates synchronously, through this transmission structure, the motor drives the transmission shaft 1 output to drive the active feeding sprocket 3 and the driven feeding sprocket 2 to rotate together at the same time, so that the active feeding chain 37 on the active feeding sprocket 3 and the driven feeding chain 27 on the driven feeding sprocket 2 move synchronously.

[0024] When this material grid conveying device needs to convey bubble cap plates of different specifications, the adjustment principle is as follows: the transmission shaft 1 does not rotate, and the two feeding moving wheels 60 are moved in one direction at the same time by moving the feeding adjustment plate 6 forward and backward. Since the engaging surface between one feeding moving wheel 60 and the feeding transmission belt 22 is located on the left side of the feeding moving wheel 60, and the engaging surface between the other feeding moving wheel 60 and the feeding transmission belt 22 is located on the right side of the feeding moving wheel 60, the part of the feeding transmission belt 22 pulled by one feeding moving wheel 60 will compensate for the part of the feeding transmission belt 22 lost by the other feeding moving wheel 60, thereby moving the feeding transmission belt 22 while keeping the feeding transmission belt 22 in a tensioned state. The movement of the feeding transmission belt 22 can drive the main feeding adjustment wheel 20 to rotate. Since the main feeding adjustment wheel 20 is connected to the driven feeding sprocket 2, the driven feeding sprocket 2 rotates synchronously. The rotation of the driven feeding sprocket 2 drives the driven feeding chain 27 to rotate, and finally the second support member 28 and the second grid plate 29 move, so that the distance between the second grid plate 29 and the first grid plate 39 changes, thereby completing the adjustment work.

[0025] Of course, the feed adjustment plate 6 can be moved by manual adjustment or by motor drive. In order to facilitate adjustment, the present invention installs a feed adjustment motor 8 on the adjustment support 9. The output end of the feed adjustment motor 8 is connected to a feed adjustment screw 80, and the feed adjustment screw 80 is threadedly connected to the feed adjustment plate 6. Through the output of the feed adjustment motor 8, the adjustment screw rotates, thereby driving the feed adjustment plate 6 to move.

[0026] The general material grid conveying device also includes a driven clamping chain, a clamp and a clamping action member 10 for driving the clamp to open. The clamp is connected to the driven clamping chain. The clamp is used to clamp the instruction manual and the blister plate together. The driven clamping chain moves synchronously with the active feeding chain 37. When the box loading position is reached, the clamp acts on the clamping action member 10, the clamp opens, and the pushing device pushes the instruction manual and the blister plate into the paper box. However, if the grid spacing changes, the position of the clamp should also be adjusted accordingly so that the clamp is in the middle of the grid spacing. Of course, if the grid spacing changes very little, the clamp can also be not used for adjustment.

[0027] To this end, the position of the clamp can be adjusted at the same time. In the present invention, a driven clamping sprocket 4 is rotatably provided on the transmission shaft 1, a driven clamping chain is wound around the driven clamping sprocket 4, a clamp is connected to the driven clamping chain, a main clamping adjusting wheel 40 with a diameter smaller than that of the driven clamping sprocket 4 is provided on the driven clamping sprocket 4, a sub-clamping adjusting wheel 41 is connected to the driven shaft 5, a clamping adjusting plate 63 is mounted on the adjusting support 9 so as to be movable back and forth, two clamping moving wheels 61 are mounted on the clamping adjusting plate 63, and a clamping auxiliary wheel 70 is mounted on the adjusting support 9, a clamping transmission belt 42 is wound around the clamping auxiliary wheel 70, the main adjusting wheel, the sub-clamping adjusting wheel 41 and the two clamping moving wheels 61, wherein the engaging surface between one clamping moving wheel 61 and the clamping transmission belt 42 is located on the left side of the clamping moving wheel 61, and the engaging surface between the other clamping moving wheel 61 and the clamping transmission belt 42 is located on the right side of the clamping moving wheel 61. The principle of adjusting the position of the clamp is the same as that of adjusting the grid spacing. By moving the clamp adjustment plate 63, the position of the clamp can be adjusted.

[0028] Of course, the clamping adjustment plate 63 can be moved by manual adjustment or by motor drive. For more convenient adjustment, a clamping adjustment motor 82 is installed on the adjustment support 9. The output end of the clamping adjustment motor 82 is connected to a clamping adjustment screw rod 84, which is threadedly connected to the clamping adjustment plate 63. Through the output of the clamping adjustment motor 82, the adjustment screw rod rotates, thereby driving the clamping adjustment plate 63 to move.

[0029] As described above, an opening member 10 for opening the clamp is installed on the outer side of the driven clamp chain, and in order to adjust the position of the clamp opening point, the present invention drives the opening member 10 to move forward and backward with the opening adjusting motor 11. By driving the opening adjusting motor 11, the position of the opening member 10 can be changed.
