Technical Field

The invention relates to a blister packaging machine, in particular to a vacuum clearing mechanism for pill shortage of a medicine plate of the blister packaging machine.

Background

Blister packaging machines are used for the production of aluminum-plastic blister packages containing pharmaceutical pills, and generally, blister packaging machines are used for packaging the pharmaceutical pills through blister forming, feeding, sealing and blanking processes. In the charging process, a plurality of blisters of the medicine plates are likely to have individual medicine pills which cannot be added, after the sealing and blanking of the medicine plates without the medicine pills are completed, the aluminum foils of the medicine plates without the medicine pills are manually stripped, and other medicine pills in the medicine plates are pulled out for recycling, but the workload is large, and the labor intensity of workers is greatly increased.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a medicine plate pill-lack vacuum cleaning mechanism which can automatically recover other pills in a pill-lack medicine plate and reduce the labor intensity of workers.

The invention is implemented by the following technical scheme:

medicine board lacks pellet vacuum clearance mechanism, its characterized in that: the filter is provided with a transverse hole, the hole wall of the transverse hole is provided with a front vent hole and a rear vent hole in the middle position, the front vent hole is communicated with a vacuum tube, the rear vent hole is communicated with the suction box through a gas receiving tube, a left filter ring and a right filter ring which are not communicated with each other are movably arranged in the transverse hole, and the filter rings are provided with a front filter hole and a rear feed hole; when the left side filter ring is in the middle position, the front filter hole and the rear feed hole of the left side filter ring are respectively aligned with the front and rear air vents, the bottom of the right side filter ring is provided with a hole communicated with the tablet collecting box, when the right side filter ring is in the middle position, the front filter hole and the rear feed hole of the right side filter ring are respectively aligned with the front and rear air vents, and the bottom of the left side filter ring is provided with a hole communicated with the tablet collecting box.

According to the vacuum clearing mechanism for the pill lacking of the medicine plate, which medicine plate has the pill lacking condition can be sensed through the detection probe in the conveying process before the medicine plate is fed and sealed, then when the medicine plate passes below the suction box, the air cylinder pushes the baffle plate to be away from the shielding of the opening at the bottom of the suction box, and under the vacuum suction effect, all other pills in the pill lacking medicine plate can be sucked into the suction box through the opening, so that the subsequent aluminum foil peeling operation of the pill lacking medicine plate is avoided, and the labor intensity of workers is greatly reduced; after the pill got into and draws the box, the baffle return sheltered from to drawing box bottom opening again, the pill that gets into and draws the box then through the admission pipe, the back air vent, in the back feed hole continued the suction to left side or right filter ring, when the pill in the filter ring on the left side piles up a certain amount, let the filter ring on the right take over the work, the pill in the filter ring on the left side then falls into the tablet and collects the box and collect, when the pill in the filter ring on the right piles up a certain amount, let the filter ring on the left side take over the work, the pill in the filter ring on the right then falls into the tablet and collects the box and collects.

The left side is filtered the circle and is filtered the circle with the right side and be disjunctor structure as the preferred for the operation of taking over of filtering the circle about being convenient for, and the left end lid that filters the circle on the left side is connected left handle, and the right end lid that filters the circle on the right side is connected right handle.

In order to facilitate observation of the quantity of the stacked pills in the left and right filtering rings, the left end cover and the right end cover are preferably made of transparent materials.

Preferably, the bottoms of all the movable baffles are in the same plane with the bottom of the suction box.

Drawings

The invention has the following drawings:

figure 1 is a schematic diagram of the operation of the present invention,

figure 2 is a schematic structural view of the present invention,

fig. 3 is a bottom view of the suction box unit of fig. 2.

Detailed Description

As shown in the figure, the vacuum clearing mechanism for the medicine plate lack pills comprises a suction box 1 and a filter 2, wherein the bottom of the suction box 1 is provided with four openings 5 side by side, with four rows of bubble holes that correspond medicine board A, every opening 5 is sheltered from by independent adjustable fender 7, the bottom of all adjustable fender 7 is in the coplanar with the bottom of absorbing box 1, the activity of baffle 7 is promoted by cylinder 6, filter 2 has horizontal hole 8, the pore wall of horizontal hole 8 is equipped with preceding air vent and back air vent at the intermediate position, preceding air vent intercommunication vacuum tube 4, back air vent absorbs box 1 through connecting pipe 3 intercommunication, two not communicating filtration circle about horizontal hole 8 internalization is equipped with, left side filtration circle 9 and right side filtration circle 10 are disjunctor structure, left end lid 12 of left side filtration circle 9 is connected left handle 11, right end lid 14 of right side filtration circle 10 is connected right handle 13. The left end cover 12 and the right end cover 14 are made of transparent materials, and the filtering ring is provided with a front filtering hole 16 and a rear feeding hole; when the left side filter ring 9 is in the intermediate position, the front filter hole and the rear feed hole of the left side filter ring 9 are respectively aligned with the front vent hole and the rear vent hole, the bottom of the right side filter ring 10 is provided with a hole communicated with the tablet collecting box 15, when the right side filter ring is in the intermediate position, the front filter hole and the rear feed hole of the right side filter ring are respectively aligned with the front vent hole and the rear vent hole, and the bottom of the left side filter ring is provided with a hole communicated with the tablet collecting box.

The working process of the invention is as follows: the medicine plate A is conveyed after feeding is finished, a detection probe arranged on a medicine plate conveying platform senses which medicine plate has a pill lack condition, then when the medicine plate passes below the suction box 1, the air cylinder 6 pushes the baffle 7 to leave the shielding of the opening 5 at the bottom of the suction box, then under the vacuum suction effect, all other pills in the pill lack medicine plate are sucked into the suction box 1 through the opening 5, after the pills enter the suction box 1, the baffle 7 returns to shield the opening 5 at the bottom of the suction box again, the pills entering the suction box 1 are continuously sucked into the left filter ring 9 through the air receiving pipe 3, the rear vent hole and the rear feed hole, when an operator observes that a certain amount of pills are accumulated in the left filter ring 9 through the left end cover 12, the left handle 11 or the right handle 13 is pushed or pulled to enable the right filter ring 10 to take over, and the left filter ring 9 leaves the working position, pill in the filtration circle 9 on the left falls into tablet collection box 15 through the bottom trompil and collects, when operating personnel observes the pill in the filtration circle on the right through the right-hand member lid and piles up a certain amount, promotes or pull handle and lets the filtration circle on the left take over the work, and pill in the filtration circle on the right also falls into tablet collection box through the bottom trompil and collects.
