Description:DESCRIPTION:
Field of the invention:
[0001] The present disclosure generally relates to the technical field of a tablet preparation, and in specific relates to, an automatic portable punching machine that manufactures a limited number of tablets for small-scale research purposes.
Background of the invention:
[0002] A tablet press, often referred to as a tablet compression or tableting machine, is a device that compresses powder formulations into tablets with consistent dimensions, weights, and shapes. The most popular and widely used form for dosing and commercializing a wide range of powdered products, mostly medications, detergents, candies, deodorants, and insect repellents, is compressed tablet form. Punch and die are used in manually operated tableting equipment.

[0003] Recently, a number of automated rotary machines have been created that combine intricate mechanics for tablet ejecting, pressing, and raw material loading with electronic controls. The majority of these presses were intended to create spherical tablets with a diameter ranging from 11 to 27 mm. An ideal tablet should be free from any visual or functional defect. Tablet specifications used to be tight, and the list of possible defects is long: variable weight, sticking, picking, capping, lamination, variable hardness, among others.

[0004] The advancements and innovations in tablet manufacture have not decreased the problems, mainly because of the complexities of tablet presses. The processing of powder is often the source of tablet defects because every product behaves differently on a tablet press machine. The production of tablets is a complex process that involves many variables and several engineering principles. Compaction is an essential manufacturing step in the manufacture of tablets, which includes compression and consolidation.

[0005] Small-scale research labs or individual researchers often face challenges in tablet production due to limited resources and space. Traditional tablet punching machines can be bulky, expensive, and inflexible, hindering experimentation with different sizes and shapes. Manually operated machines require constant monitoring and can be inconsistent in output. Therefore, there is a need for an automatic portable punching machine that is portable, cost-effective and flexible.

[0006] In existing technology, a tablet press is known. The tablet press comprises a base, a press member, an actuator, a load sensor, a digital encoder and an electronic controller. The tablet press is configured to press for use in producing pharmaceutical tablets. However, the tablet press utilizes multiple components for designing, which is expensive. Moreover, the tablet press needs human intervention to change the shape and size of the tablets.

[0007] In conventional methods, the tablet formation devices, which are in existence have different specifications and sizes. The tablets of different sizes are not produced simultaneously, thereby obtaining low production efficiency. For example, if the user needs to produce multiple sizes of tablets then the user needs to change the dies of the tablet formation device for obtaining the required sizes. If the powder is less in the tablet formation device for producing the tablet then the user needs to check the tablet formation device whether the powder is sufficient or not.

[0008] Therefore, there is also a need for an automatic portable punching machine that is utilized for producing a limited number of tablets for small-scale research purposes. There is also a need for an automatic portable punching machine that is simple and utilizes fewer components. There is also a need for an automatic portable punching machine that eliminates the need for human intervention to change the shape and the size of the tablets.

[0009] There is also a need for an automatic portable punching machine that is simple, inexpensive and flexible. There is also a need for an automatic portable punching machine that eliminates constant monitoring and provides consistent output. Further, there is also a need for an automatic portable punching machine that provides real-time feedback on the amount of raw material present in the automatic portable punching machine.
Objectives of the invention:
[0010] The primary objective of the invention is to provide an automatic portable punching machine that produces limited number of tablets for small scale research purposes.

[0011] Another objective of the invention is to provide an automatic portable punching machine that is simple and utilizes less components for producing tablets, thereby reducing preparation cost.

[0012] The other objective of the invention is to provide an automatic portable punching machine that eliminates the need of human intervention for changing the shape and the size of the tablets.

[0013] The other objective of the invention is to provide an automatic portable punching machine that notifies the user if there is not enough powder in the automatic portable punching machine.

[0014] Yet another objective of the invention is to provide an automatic portable punching machine that selectively dispenses the required amount of powder based on user selection for preparing tablets.

[0015] Further objective of the invention is to provide an automatic portable punching machine that provides real-time feedback on the amount of raw material present in the automatic portable punching machine.

If the drug powder in the feeding hopper 106 is more than 100 mg then the controller 116 activates the lower pressing member 112. If the drug powder in the feeding hopper 106 is less than or equal to 100 mg then the controller 116 does not activate the lower pressing member 112.

[0060] If the drug powder in the feeding hopper 106 is more than 100 mg then the controller 116 activates the die plate assembly 102 to extract the inner, middle and outer portions of the plurality of concentric plates 104 so as to form as the cavity. Next, the controller 116 activates the control valve 108 to dispense 110 mg of the drug powder. In specific, the controller 116 is programmed such that 10 more percent of drug powder than selected is dispensed onto the die plate assembly 102.

[0061] Now, the controller 116 activates the wiping member 126 to wipe the excess amount of the drug powder on the cavity so that only 100 mg of the drug powder remains in the cavity. Next, the controller 116 actuates the first, the second and the third portions of the plurality of lower punching members 122 in the lower pressing member 112 for providing support to the die plate assembly 102 during the punching operation. Later, the controller 116 actuates the first, the second and the third portions of the plurality of upper punching members 124 to punch the drug powder in the die plate assembly 102 based on the user inputs for preparing the 100 mg tablet.
