Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical equipment, and in particular relates to an automatic auxiliary medicine handling device for pharmaceutical production. Background Art

[0002] At present, on the pharmaceutical packaging production line, the medicine plates enter the aggregation through the conveyor belt. After the flipping and stacking actions are completed in the aggregation machine, they are transported to the pillow packaging machine through the clamps for subsequent packaging. The existing aggregation machine can only stack three layers of medicine plates, and the pillow packaging machine has been upgraded and can currently realize the stacking and transportation of five layers of medicine plates. Therefore, two layers of medicine plates need to be manually added. In production, the manual speed cannot keep up with the automatic production speed due to the high production speed. The discharged medicine plates need to be sorted and stored in the preparation box in advance, and the medicine plates can be quickly and conveniently put into the pillow packaging machine for 5-layer stacking in the formal production. This production method requires a lot of manual time to organize the medicine plates, which affects production efficiency, and there is a quality risk of unreliable manual intervention. The cost of modifying the aggregation machine is too high and needs to be modified abroad, resulting in a too long cycle. Therefore, it is very necessary to design an automatic auxiliary medicine handling equipment that can be applied between the aggregation machine and the pillow packaging machine to replace manual operation.

DETAILED DESCRIPTION

[0034] The present invention is described in further detail below in conjunction with the accompanying drawings to facilitate a better understanding of the present technical solution.

[0035] The present invention relates to an automatic auxiliary medicine handling device for pharmaceutical production, which is used to be connected with the discharge outlet of the gathering machine and the inlet of the pillow packaging machine. The overall structure is as follows: Figure 1 As shown, it includes a frame 1, a combined package pushing mechanism 4 arranged on the frame 1, a driving wheel mechanism 5, an inlet medicine plate buffer pressing plate device 6 and a flip buffer pressing plate device 7, a discharge auxiliary device 8, and a collection track device 9. The specific structure of the frame 1 is as follows Figure 4-5 As shown in Figure 12, it includes a support leg 101 and a machine docking plate 102 installed on the support leg 101, a plurality of main body drive mounting base plates 103 and a discharge bracket 104 are fixed on the machine docking plate 102, and adjacent main body drive mounting base plates 103 form a conveying channel. The present invention is preferably provided with three channels, and a track fixing frame 105 is correspondingly installed on the main body drive mounting base plate 103, and a side rail 2 is installed on the track fixing frame 105. The side rail 2 consists of a horizontal portion and an arc-shaped portion. Side rail mounting plates 201 are correspondingly provided on both sides of the arc-shaped portion of the side rail 2, and the tops of the two side rail mounting plates 201 are connected by a connecting plate 3.

[0036] In order to achieve smooth sliding of the medicine plate in the side rail 2, three PTFE guide strips are fixed to the inner wall of the side rail 2 by screws, and guide rail slots 202 are formed between adjacent PTFE guide strips. The edge of the medicine plate moves along the guide rail slot 202. The gap between each guide rail slot 202 is 1.75mm. This setting effectively utilizes the good lubricating property of the surface of the PTFE material to ensure that the friction of the medicine plate product is reduced as much as possible when passing, thereby reducing the resistance of the cylinder push and the equipment failure rate, and improving the service life of the equipment.

[0037] like Figure 6 As shown, the combined package pushing mechanism 4 includes a front limit adjustment section rod 401, a rear limit adjustment section rod 402, a combined cylinder and a pushing fork 403 driven by the combined cylinder, which is used to push the positioned medicine plate along the horizontal part of the side rail 2, wherein the combined cylinder includes a Y-axis cylinder 404 and a Z-axis cylinder 405, the Y-axis cylinder 404 and the Z-axis cylinder 405 are respectively fixed on the cylinder connecting seat 406, the Z-axis cylinder 405 is connected to the telescopic tube fixing plate 408 through the telescopic air pipe 407, and the telescopic tube fixing plate 408 is correspondingly installed on the machine docking plate 102. This setting can effectively avoid interference during high-speed movement of the cylinder, and the Y-axis cylinder 404 and the Z-axis cylinder 405 provide signal feedback by detecting the position photoelectric 409. Specifically, the telescopic air tube 407 of the Z-axis cylinder 405 adopts a spring tube to adapt to the backward movement of the Y-axis cylinder 404, which has the effect of telescoping and extending. The in-position photoelectric 409 is used as the start and stop signal to control the Y-axis cylinder 404 and the Z-axis cylinder 405 to achieve continuous cyclic operation. When the Y-axis cylinder 404 reaches the set position within the specified time of 0.3 seconds, the in-position photoelectric 409 stops running immediately after detecting the signal, and the online signal device also stops running.

[0038] like Figure 7 、 13As shown, the driving wheel mechanism 5 includes a wheel motor 501, a driving spindle 502, a wheel 503 and a spindle fixing seat 504. The spindle fixing seat 504 is fixedly mounted on the main drive mounting base 103. One end of the driving spindle 502 is connected to the output end of the wheel motor 501. The other end of the driving spindle 502 passes through the spindle fixing seat 504 in sequence and is connected to the outermost spindle fixing seat 504. The wheel 503 is sleeved on the driving spindle 502, and three levers 505 are integrally arranged on the wheel 503. The lever 505 is provided with a fixing hole, and an extension rod 506 is installed on the fixing hole by screws. During the specific action, when the Y-axis cylinder 404 completes the action, the wheel motor 501 is started, and the wheel 503 is driven to rotate the lever 505 120°. The rotation of the lever 505 drives the extension rod 506 to move and push the medicine plate to the corresponding position. The setting of the extension rod 506 is convenient for replacement, which can better protect the lever 505 and form a clockwise rotation. This setting can firstly reduce the weight of the wheel 503 itself; and it is more convenient to disassemble and replace; thirdly, the screws are reinforced according to the force direction of the lever 505, so that the lever 505 can exert the maximum mechanical effect; fourthly, the length of the lever 505 is shortened to improve the strength and service life of the wheel 503.

[0039] like Figure 8 As shown, the main function of the entrance medicine plate buffer pressure plate device 6 is to slow down the inertia of the medicine plate when receiving the pushed-in medicine plate so that the medicine plate is buffered in place to prevent the medicine plate from flying out of the track during high-speed operation. It is arranged above the horizontal part of the side rail 2, and includes a buffer frame 601, a balance block 602 and an elastic fixing rod 603. The two ends of the buffer frame 601 are connected to the top of the track fixing frame 105. The elastic fixing rod 603 is arranged below the buffer frame 601 through the balance block 602, and a spring piece 604 is installed below the elastic fixing rod 603. This arrangement can reduce the problem of unstable buffer positioning caused by uneven friction when the medicine plate product has a height error. The two ends of the spring piece 604 are respectively flipped to the top of the elastic fixing rod 603 and reinforced by screws. A gap of 1 mm is left between the spring piece 604 and the elastic fixing rod 603, and the spring piece 604 at the rear end of the elastic fixing rod 603 is bent upward into an arc shape to increase the elastic effect.

[0040] like Figure 9As shown, the flipping buffer pressure plate device 7 is arranged on the arc-shaped part of the side rail 2, including a buffer pressure plate 701, a front end fixing frame 702, a rear end limiting frame 703 and a spring 704. The front end fixing frame 702 is respectively connected to the top of the track fixing frame 105 and the upper end of the buffer pressure plate 701, and the rear end limiting frame 703 is respectively connected to the upper surface of the side rail 2 and the lower end of the buffer pressure plate 701. Specifically, the two ends of the rear end limiting frame 703 are respectively connected to the upper surface of the side rail 2 through adjusting nuts, and the two ends of the spring 704 are respectively connected to the front end fixing frame 702 and the rear end limiting frame 703; this device plays a vital role in the flipping link, and the pin shaft on the front end fixing frame 702 is used as the base point and the spring tension is used to make the buffer pressure plate generate downward pressure, and the size of the downward pressure can be adjusted by the adjusting nut on the rear end limiting frame. The setting of this device enables the inertial force to be effectively controlled. When a card fails, the extrusion force is greater than the pressure under the spring, which can force it to spring open, thereby protecting the accuracy of the equipment. At the same time, it helps to extend the service life of the equipment and facilitates manual cleaning of the medicine plate inside the track.

[0041] like Figure 10 As shown, the discharge auxiliary device 8 is used to ensure the stable uprightness of the medicine plate after the flipping is completed, including a brush 801, an auxiliary bracket 802 and a medicine-blocking cylinder 803 arranged on the auxiliary bracket 802. The end of the cylinder rod of the medicine-blocking cylinder 803 is fixed with a medicine-blocking block 804. The medicine-blocking block 804 is arranged above the outlet end of the arc-shaped portion of the side rail 2, and the brush 801 is installed at the lower end of the arc-shaped portion of the side rail 2. This device utilizes the characteristics of the left and right brushes 801 to insert 3mm of the width of both sides of the medicine plate into the inside of the brush 801 at the moment the medicine plate comes down, thereby increasing the stability of the medicine plate. At the same time, the medicine-blocking cylinder 803 is actuated to drive the medicine-blocking block 804 to move down to the front end of the medicine plate to prevent the upper end of the medicine plate from tilting outward.

[0042] like Figure 11 As shown, the collection track device 9 is mainly used to stand the medicine plates upright and arrange them in order in the track for easy manual handling. It includes a tray 901, an embedded discharge cylinder push fork 902, a discharge track 903 and a slider 904. The discharge track 903 is installed on the tray 901. The sliders 904 on both sides of the same discharge track 903 are connected by a slider mounting plate 905. A discharge buffer block 906 is fixed on the slider mounting plate 905. Its specific operation is that the cylinder action drives the discharge cylinder push fork 902 to push the medicine plate out from the inside of the track. When the medicine plate is quickly pushed into the discharge track 903, there are track cotton and discharge buffer blocks 906 set on both sides of the discharge track 903. Under the dual action of the track cotton and the discharge buffer blocks 906, the medicine plates are upright and can be arranged in order.

[0043] Combine Figure 2-3 Briefly describe the working steps of the invention:

[0044] Step 1: The medicine board enters the track. In automatic mode, the medicine board detects the transmitting and receiving optical axes of the photoelectric device, and starts the operation of the device along the falling signal (1 changes to 0) to start working;

[0045] Step 2: The Z-axis cylinder drives the push fork to move upward to complete one action, and the Y-axis cylinder pushes the product medicine plate backward to the set position to complete the second step;

[0046] Step 3: Drive the main shaft to drive the wheel lever to continue pushing the medicine plate to pass through the curved part of the side rail to reach the position to complete the third step;

[0047] Step 4: The ejection cylinder pushes the medicine plate and reaches the fourth step under the action of the brush and the medicine blocking cylinder.
