Description

Technical Field

[0001] The utility model relates to the technical field of medicine packaging equipment, in particular to a feeding mechanism for spherical pills. Background Art

[0002] The plastic shell of Chinese medicine pills is usually composed of two hemisphere shells. The Chinese medicine can be ground appropriately and filled into it, and then the two hemisphere shells are glued together by a machine to make a uniform pill. This method can make it easier to take and can also enhance the encapsulation of the medicine, making it easier to store and transport the medicine.

[0003] In the existing pill packaging equipment, two unloading stations are generally set up to unload qualified pills and unqualified pills respectively, thus requiring two sets of unloading structures, which leads to increased equipment cost, larger size of the entire equipment, and increased equipment footprint. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology, the utility model proposes a feeding mechanism for spherical pills.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A feeding mechanism for spherical pills, comprising a bearing seat for bearing pills, a feeding structure arranged at the bottom of the bearing seat, and a feeding pipe group arranged at the side of the bearing seat;

[0007] The ejection structure includes an ejection rod, an ejection unit driving the ejection rod to move up and down, and a rotation unit driving the ejection rod to rotate. A discharge hole for the ejection rod to pass through is formed on the bearing seat, and a discharge slope is formed at the end of the ejection rod;

[0008] The discharge pipe group includes a qualified product discharge pipe and a defective product discharge pipe respectively arranged on both sides of the supporting seat, and the qualified product discharge pipe and the defective product discharge pipe are formed with discharge holes for pills to be placed in. The ejector rod drives the pills to separate from the supporting seat so that the pills are placed into the discharge holes of the qualified product discharge pipe or the defective product discharge pipe along the discharge slope.

[0009] Preferably, a guide tube is rotated above the bearing seat, and a disengagement hole for discharging pills is formed on the guide tube. The guide tube rotates so that the disengagement hole is arranged opposite to the drop hole of the qualified product discharge tube or the defective product discharge tube. Through the above improvements, as the ejection rod moves upward, the pills will be pushed into the guide tube. As the pills rise to a certain height, the pills will be discharged from the disengagement hole under the action of the discharge slope and enter the qualified product discharge tube or the defective product discharge tube. Since the pills can only be discharged from the disengagement hole of the guide tube, and the guide tube rotates with the ejection rod, the qualified products and the defective products are prevented from mixing.

[0010] Preferably, a jet pipe is provided on the side of the guide pipe, and the jet pipe is disposed opposite to the separation hole.

[0012] Preferably, the qualified product discharging pipe and the defective product discharging pipe include a first discharging section connected to the guide pipe and a second discharging section for discharging the pill, and the first discharging section is disposed opposite to the separation hole. Through the above improvement, the pill first discharges from the separation hole into the first discharging section and then flows into the second discharging section for discharging. The first discharging section and the second discharging section are arranged in a staggered manner, thereby reducing the floor area of the qualified product discharging pipe and the defective product discharging pipe to reduce the volume of the entire device.

[0013] Preferably, the first discharging section and the second discharging section are inclined, and the connection area between the first discharging section and the second discharging section is arc-shaped. Through the above improvement, the pill can roll out better, improving the discharging efficiency and smoothness.

[0014] Preferably, the blanking pipe group is arranged on the machine table, a receiving frame is arranged on the machine table, the receiving frame is located below the output end of the qualified product discharging pipe, and a material dropping groove is formed on the machine table, and the material dropping groove is located below the output end of the defective product discharging pipe. Through the above improvement, the qualified pills are received in the receiving frame, and the unqualified pills are placed in the material receiving groove, and the unqualified pills are collected by the device for collecting unqualified pills arranged in the machine table to avoid mixing of qualified pills and unqualified pills.

[0015] Preferably, a material dropping counter is arranged on the side of the second discharging section. Through the above improvement, the number of defective product pills and qualified pills can be calculated respectively, so as to accurately calculate the production capacity and the qualified rate of the product.

[0016] Preferably, a shock pad is arranged in the receiving frame. Through the above improvement, it is avoided that the shell of the pill opens during the falling process, resulting in defects.

[0017] Preferably, a guiding inclined surface is formed at the bottom of the discharging hole. Through the above improvement, the upward movement of the ejector rod is guided, further improving the smoothness of the pill discharging.

[0018] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0019] A qualified product discharge pipe and a defective product discharge pipe are respectively arranged on both sides of the bearing seat, a discharge slope is formed at the end of the ejector rod, and the rotating unit drives the ejector rod to rotate, thereby controlling the position of the discharge slope, and the ejector rod drives the pills to leave the bearing seat, so that the pills are placed into the discharge holes of the qualified product discharge pipe or the defective product discharge pipe along the discharge slope, so that one discharge mechanism can discharge qualified pills and unqualified pills separately, which not only reduces the cost of the equipment, but also reduces the size of the equipment.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0031] like Figure 1-8 As shown, a feeding mechanism for spherical pills includes a bearing seat 2 for bearing pills, a feeding structure 3 arranged at the bottom of the bearing seat 2, and a feeding pipe group 3 arranged at the side of the bearing seat 2.

[0032] Specifically, the ejection structure 3 includes an ejection rod 101, an ejection unit 102 that drives the ejection rod 101 to move up and down, and a rotation unit 103 that drives the ejection rod 101 to rotate. A discharge hole 104 is formed on the supporting seat 2 for the ejection rod 101 to pass through, and a discharge slope 105 is formed at the end of the ejection rod 101.

[0033] Furthermore, the discharge pipe group 3 includes a qualified product discharge pipe 201 and a defective product discharge pipe 202 respectively arranged on both sides of the supporting seat 2, and the qualified product discharge pipe 201 and the defective product discharge pipe 202 are formed with discharge holes 203 for pills to be placed in. The ejector rod 101 drives the pills to separate from the supporting seat 2, so that the pills are placed into the discharge holes 203 of the qualified product discharge pipe 201 or the defective product discharge pipe 202 along the discharge slope 105.

[0034] A qualified product discharge pipe 201 and a defective product discharge pipe 202 are respectively arranged on both sides of the supporting seat 2, and a discharge slope 105 is formed at the end of the ejector rod 101. During the entire unloading process, the rotating unit 103 first drives the ejector rod 101 to rotate, so as to control the position of the discharge slope 105. The ejector rod 101 rises under the action of the ejector unit 102 and drives the pills to separate from the supporting seat 2. The pills are placed into the qualified product discharge pipe 201 or the defective product discharge pipe along the discharge slope 105. The qualified pills and the defective pills can be unloaded separately by one unloading mechanism, which not only reduces the cost of the equipment, but also reduces the size of the equipment.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown in the figure, for a further explanation of the pill discharging guiding and limiting in this embodiment, a guiding tube 301 is rotatably arranged above a bearing seat 2. A separation hole 302 for discharging pills is formed on the guiding tube 301. The guiding tube 301 rotates to make the separation hole 302 face the material dropping hole 201 of the qualified product discharging tube or the material dropping hole 203 of the unqualified product discharging tube relatively.

[0036] As the ejector rod 101 moves upward, the pill will be pushed into the guiding tube 301. As the pill rises to a certain height, the pill will be discharged from the separation hole 302 under the action of the discharging inclined surface 105 and enter the qualified product discharging tube 201 or the unqualified product discharging tube. Since the pill can only be discharged from the separation hole 302 of the guiding tube 301 and the guiding tube 301 rotates with the ejector rod 101, the mixing of qualified products and unqualified products is avoided.

[0037] Among them, the guiding tube 301 is connected with a driving motor 408 or a rotary cylinder, which can drive the guiding tube 301 to rotate, so as to cooperate with the discharging inclined surface 105 on the ejector rod 101, and make the pill only be discharged from a limited position.

[0038] Furthermore, an air spraying tube 303 is arranged on the side of the guiding tube 301. The air spraying tube 303 is arranged opposite to the separation hole 302. When the pill rises to a certain height, the air spraying tube 303 will spray air to eject the pill out of the separation hole 302, thus improving the discharging efficiency and smoothness.

[0039] Preferably, a discharging channel 304 for the pill to pass through is formed in the guiding tube 301. A position sensor 305 is arranged in the discharging channel 304. The position of the position sensor 305 is higher than that of the separation hole 302. When the pill rises to a certain height, the position sensor 305 will sense the pill, and then send a signal to the air spraying tube 303 to make the air spraying tube 303 spray air, so that the pill is discharged from the separation hole 302, avoiding the waste of the air source.

[0040] As Figure 1 、 Figure 2 、 Figure 4 shown in the figure, for a further explanation of the implementation manners of the qualified product discharging tube 201 and the unqualified product discharging tube in this embodiment, the qualified product discharging tube 201 and the unqualified product discharging tube include a first discharging section 401 connected to the guiding tube 301 and a second discharging section 402 for discharging pills. The first discharging section 401 is arranged opposite to the separation hole 302.

[0041] The pill is first discharged from the separation hole 302 into the first discharging section 401, and then flows into the second discharging section 402 for discharging. The first discharging section 401 and the second discharging section 402 are arranged in a staggered manner, thus reducing the floor area of the qualified product discharging tube 201 and the unqualified product discharging tube, and reducing the volume of the whole equipment.

[0042] Furthermore, the first discharging section 401 and the second discharging section 402 are inclined, and the connecting area between the first discharging section 401 and the second discharging section 402 is arc-shaped, enabling the pills to roll out more smoothly, thus improving the discharging efficiency and smoothness.

[0043] In addition, the blanking pipe group 3 is arranged on the machine table 1, and a receiving frame 403 is arranged on the machine table 1. The receiving frame 403 is located below the output end of the qualified product discharging pipe 201, and a blanking chute 404 is formed on the machine table 1. The blanking chute 404 is located below the output end of the defective product discharging pipe.

[0044] The qualified pills are received in the receiving frame 403, and the unqualified pills are placed into the receiving chute. The device for collecting unqualified pills arranged in the machine table 1 is used to gather the unqualified pills, preventing the mixing of qualified and unqualified pills.

[0045] Preferably, a blanking counter 405 is arranged on the side of the second discharging section 402, which can respectively count the numbers of defective pills and qualified pills, thereby accurately calculating the production capacity and the qualified rate of the products.

[0046] Such as Figure 7 shown, preferably, a shock pad 406 is arranged in the receiving frame 403 to prevent the outer shell of the pills from opening during the falling process, thus avoiding defects.

[0047] Such as Figure 8 shown, preferably, a guiding inclined surface 407 is formed at the bottom of the discharging hole 104 to guide the ejector rod 101 during its upward movement, further improving the smoothness of pill discharging.

[0048] This specific embodiment is only an explanation of the present invention, and it is not a limitation to the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
