Since the worm 451 and the worm wheel 452 constitute a speed reducing mechanism; therefore, the manual operation is labor-saving, and the precision is high; and due to its own structure, it will not cause reversion under the action of its own weight.

The lot number press 44 includes a bottom plate 445, side plates 446 provided on both sides above the bottom plate, and a back plate 447 provided behind the bottom plate and the side plates, and may be provided with a cover plate as needed; the bottom plate, the side plates and the back plate form a drawer-like space; a reciprocating mechanism (a left-right reciprocating mechanism in fig. 2) is arranged on the bottom plate; a servo motor 444 is arranged on the back of the substrate, and a shaft of the servo motor 44 penetrates through the back plate and is in transmission connection with a reciprocating mechanism 448; the reciprocating mechanism is driven by the servo motor to do left-right reciprocating stamping action; a pressing pad 443 is arranged at the front end of the reciprocating mechanism; a printing steel plate 442 is arranged on the side plate corresponding to the press pad; openings for PVC bubble caps to pass through are arranged on the bottom plate and the cover plate; the hole through which the PVC bubble cap passes is positioned between the press pad and the printing steel plate; the pressing pad presses the PVC bubble cap on the printing steel plate under the drive of the reciprocating mechanism to complete the stamping action.

In actual operation, the servo motor 444 needs to be adjusted and controlled by a PLC or the like to synchronize each stamping action with each rise (or fall) of the PVC blisters so that each row of PVC blisters can be stamped.

Medicine board quantity detecting unit

Because the deformation of the two ends of the medicine board in the length direction of the medicine board can occur more or less in the appearance, taking the medicine board with the loading amount of two boards per box as an example, when the deformation amount is large, the two ends of the third board can be downwards bent to the height of the second board, and if the conventional opposite-shooting photoelectric switch is adopted to detect the quantity of the medicine boards, false detection can occur.

The medicine board quantity detecting unit comprises a product chain 51, wherein a base 52 is arranged on one side of the product chain, and a lifting device 56 is arranged on the base; a sliding plate 65 which can move up and down along with the lifting device is arranged on the lifting device; a swing arm 57 is hinged on the sliding plate; the free end of the swing arm is provided with a rotating shaft 591, and one end of the rotating shaft near the product chain is provided with a rotating seat 59 with a plurality of radial support arms; the support arms are arranged at equal intervals; a detection rod 510 is horizontally arranged at the end part of each support arm towards the product chain, and the detection rod 510 can be made of plastic materials;

wherein, a detection window is arranged in the middle of the swing arm; a detection sheet 8 is arranged above and below the detection window respectively; a detecting device 512 is arranged in the middle of the detecting sheet;

the product chain synchronous driving device is in transmission connection with the rotating shaft so that each working position of the product chain in advance corresponds to each supporting arm on the rotating seat to rotate by one working position. That is, each time the product chain moves forward one station; the arms of the swivel are also rotated by one station, just so that the test bar on the next arm can press against the object 511 to be packaged on the product chain of the next station. When the next arm continues to rotate to a position directly above the object 511 (this is because the product chain is driven by the servo motor, and the rotating base is synchronously driven by the synchronous belt, the position of each arm on the rotating base can be calculated, however, other manners are also possible, for example, a position sensor (such as a hall element) is arranged on the swing arm corresponding to the position directly above the object 511, and a magnet is arranged on each arm corresponding to the position, and when the arm rotates to the position, the hall element detects and emits a signal.) the PLC starts to receive the detection signal of the detection device 512; when no abnormal signal is detected, the swing arm is not sunk, and the number of the medicine plates reaches the set loading amount. When the number of the plates is detected to not reach the set loading amount, the swing arm sinks, and the detection device (the proximity switch) detects the upper detection piece; and when the number of the detected plates exceeds the set loading amount, the swing arm is lifted, and the proximity switch detects the lower detection piece. Therefore, as long as the number of the medicine plates is abnormal, the proximity switch is conducted to feed signals back to the boxing machine.

As shown in the figure, the lifting device is a manual lifting device, and comprises an upper baffle plate and a lower baffle plate, two guide rails 561 are arranged between the upper baffle plate and the lower baffle plate at intervals, and sliding blocks 562 are slidably arranged on the two guide rails; a screw 563 is rotatably provided between the two guide rails; the upper end of the screw rod passes through the upper baffle plate upwards and is connected with the handle 564; the sliding block is in threaded connection with the screw rod through a nut; the sliding plate is arranged on the sliding block.

As a further improvement of the invention, a limiting structure 566 is arranged on the sliding plate corresponding to the swing arm. The limiting structure 566 can be that a limiting bolt is arranged at the bottom of the sliding plate corresponding to the swing arm 57 so as to prevent the swing arm from sinking more when the number of the plates does not reach the set loading amount, and the normal operation of the product chain is affected.

The product chain synchronous driving device can be driven by a servo motor, and can also be completed by a mode of combining chain transmission and synchronous belt transmission. As indicated by a broken line in the figure, the driven sprocket shaft of the product chain 51 changes the rotation direction through power chain transmission and through the reversing gear 53, then the synchronous belt transmission 55 in the device is driven through the chain transmission 4, and finally the power is transmitted to the rotating shaft 59 through the synchronous belt, so that when the packaged objects 511 arranged at intervals on the product chain move rightwards by one unit cell station, the rotating seat 59 rotates for 1/5 circle along the rotation direction meshed with the packaged objects, and one-to-one detection can be realized on each packaged object.

In order to adapt to medicine plates with different thicknesses, the swing arm 57 of the device needs to be adjusted in height, the correct medicine plate loading amount is taken as a height reference, the height of the swing arm is adjusted, the rotating seat 59 is rotated to enable the detection rod 510 to be just vertically pressed onto the medicine plate, then the detection piece 58 is adjusted, the proximity switch 512 is just placed in a gap between the upper detection piece and the lower detection piece, and the detection piece is ensured not to be detected, so that when the number of detected plates does not reach the set loading amount, the swing arm is sunk, and the proximity switch can detect the upper detection piece; and when the number of the detected plates exceeds the set loading amount, the swing arm is lifted, and the proximity switch detects the lower detection piece. Therefore, as long as the number of the medicine plates is abnormal, the proximity switch is conducted to feed signals back to the boxing machine.

When the packaged object is a double-aluminum medicine plate or a pillow bag, the material is softer than the PVC medicine plate, and if the small-area detection rod is simply used for contact detection, a relatively obvious detection trace is left on the packaged object, and even the packaged object is punctured. To avoid this, the test rod 510 is designed as a cylinder of a length greater than the total length of the object to be packaged so as not to damage the surface of the object 511.

The product chain mainly comprises four chains, wherein the four chains are divided into two groups, and the two groups of chains can mutually move so as to adapt to different medicine plate (or medicine box) sizes; the spacing can be kept constant after adjustment in place. When the width of the medicine plate (or medicine box) is changed, the distance between the two groups of chains needs to be adjusted, and the common means are manual adjustment, which is tedious and laborious. The automatic adjustment needs to drag one group of chains to move by using a motor, and the chain is shifted from the other group of chains. However, how to design motor drag, how to place cable winding and other problems have not been solved.

the motor 63 drives the vertical screw to rotate in the forward direction or the reverse direction, so that the lifting plate can lift relative to the fixed plate.

In operation, when power is input to the driving shaft 620, the driving shaft 620 drives the driving sprocket 619, the driving sprocket 621 and the driving pulley 628 to rotate, the driving pulley 628 drives the adjusting pulley 65 to rotate through the driving synchronous belt 627, the adjusting pulley 65 drives the driving shaft 611 to rotate, the driving shaft 611 drives the left driving synchronous pulley 69 and the right driving synchronous lower pulley 612 to rotate, the left driving synchronous pulley 69 drives the left driven synchronous pulley 626 to rotate through the left synchronous belt 610, and the right driving synchronous lower pulley 612 drives the right driven synchronous pulley 615 to rotate through the right synchronous belt 613, and the left driven synchronous pulley 626 and the right driven synchronous pulley 615 drive the driven sprocket 617 and the driven sprocket 624 to rotate, respectively. Driven sprocket 624 and driven sprocket 617 drive a set of chains, and drive sprocket 619 and drive sprocket 621 drive a set of chains, at this time, the two sets of chains keep the relative positions unchanged and move together with drive shaft 620, and at this time, are in a normal running state.

When the machine is stopped, the driving shaft 620 is in transmission connection through a speed reducing device, a motor and the like, so that the driving pulley 628 driven by the driving shaft 620 drags the driving sprocket 619, the driving sprocket 621 and the driving pulley 628 to rotate and not rotate; when the adjustment motor 63 drives the screw 631 to rotate upward, the lower belt pulley 61 and the upper belt pulley 66 move upward with the lifting plate 62 as the adjustment motor 63 moves upward, and because the total circumference of the driving timing belt 627 is unchanged, the driving belt 628 cannot rotate, resulting in the adjustment belt pulley 65 rotating clockwise, the adjustment belt 65 rotating dragging transmission shaft 611 rotating clockwise, the transmission shaft 611 dragging the left transmission timing belt 69 and the right transmission timing lower belt pulley 612 rotating clockwise, the left transmission timing belt 69 dragging the left driven timing belt 626 rotating clockwise through the left timing belt 610, the right transmission timing lower belt pulley 612 dragging the right driven timing belt 615 rotating clockwise through the right timing belt 613, the left driven timing belt 626 and the right driven timing belt 615 dragging the driven sprocket 617 and the driven sprocket 624 rotating clockwise, respectively. At this time, a set of chains driven by the driven sprocket 624 and the driven sprocket 617 is shifted rightward with respect to a set of chains driven by the driving sprocket 619 and the driving sprocket 621.

When the machine is stopped, the driving shaft 620 does not rotate, so that the driving pulley 628 driven by the driving shaft 620 drags the driving sprocket 619, the driving sprocket 621 and the driving pulley 628 to rotate, when the adjusting motor 63 drives the screw 631 to reversely rotate and descend, the lifting plate 62 moves downwards along with the adjusting motor 63, the lower pulley 61 and the upper pulley 66 move downwards along with the lifting plate 62, because the total circumference of the driving synchronous belt 627 is unchanged, the driving pulley 628 cannot rotate, the adjusting pulley 65 rotates anticlockwise, the adjusting pulley 65 rotates and drags the transmission shaft 611 to rotate anticlockwise, the transmission shaft 611 drags the left transmission synchronous pulley 69 and the right transmission synchronous lower pulley 612 to rotate anticlockwise, the left transmission synchronous pulley 69 drags the left driven synchronous pulley 626 to rotate anticlockwise through the left synchronous belt 610, and the right transmission synchronous lower pulley 612 drags the right driven synchronous pulley 615 to rotate anticlockwise through the right synchronous belt 613, and the left driven synchronous pulley 617 and the driven sprocket 624 to rotate anticlockwise respectively. At this time, a set of chains driven by the driven sprocket 624 and the driven sprocket 617 is shifted leftward with respect to a set of chains driven by the driving sprocket 619 and the driving sprocket 621.
