Description

Technical Field

[0001] The present invention relates to the technical field of food packaging, and particularly to a supply mechanism for row-connected articles.

Background Art

[0002] Row-connected articles refer to products placed in packaging bags, and the packaging bags are connected together. Common row-connected articles in the prior art include row-connected straws, row-connected folding spoons, etc. Usually, these row-connected articles are quantitatively placed into packing boxes or packaging boxes in the last stage of the filling process. For example: after placing a certain number of yogurt cups into the packaging box, a group of row-connected straws need to be inserted between two rows of yogurt cups. In order to ensure that the number of straws in the row-connected straws is consistent with the number of yogurt cups, a supply mechanism needs to be set up to count and cut the row-connected straws. After cutting, the row-connected straws fall onto the support rod below the supply mechanism, and then the row-connected straws on the support rod are scraped into the receiving groove on the conveying block by the conveying block. Finally, the row-connected straws in the receiving groove are inserted into the packaging box by the tube inserting device. The row-connected straws in the prior art usually stack together in a stacked state after falling into the receiving groove. Since the packaging bag has a certain flexibility, during the process of inserting into the packaging box, when one end of the row-connected straw is outside the receiving groove, it will spread out, and the spread row-connected straws will be blocked by the yogurt cups and cannot be inserted into the gap, resulting in the phenomenon of missed insertion of straws.

Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a supply mechanism for row-connected articles, which can make the row-connected articles fall into the receiving groove of the conveying block in a curled state to avoid the row-connected articles from spreading out during the later insertion into the packaging box, thereby avoiding the phenomenon of missed insertion of row-connected articles.

[0004] To solve the above technical problem, the present invention adopts the following technical solutions:

[0005] A supply mechanism for continuous-row items, comprising a subcontracting rotating wheel, a cutter, a support rod, and a conveying block. A plurality of grooves and cutter slots are provided on the circumferential side of the subcontracting rotating wheel. The cutter slots are located between two adjacent grooves. The continuous-row items are wound around the subcontracting rotating wheel so that each item is sequentially inserted into the groove. The cutter cuts into the cutter slot to cut off the continuous-row items. The support rod is located below the subcontracting rotating wheel and extends along the conveying direction to receive the falling continuous-row items. The conveying block includes a receiving groove and a scraping plate. The scraping plate scrapes the continuous-row items on the support rod into the receiving groove. The supply mechanism further includes a blowing mechanism, as well as a baffle and a brush located above the support rod. An annular avoidance groove is provided on the outer peripheral side of the subcontracting rotating wheel. One end of the baffle is inserted into the avoidance groove, and the other end extends outside the avoidance groove and extends along the conveying direction. The brush is arranged near the end of the baffle away from the subcontracting rotating wheel and contacts the support rod. The blowing mechanism includes an air pipe, and the air outlet of the air pipe faces the baffle to blow the cut continuous-row items off the subcontracting rotating wheel.

[0006] In the above supply mechanism for continuous-row items, the air pipe is an arc-shaped pipe arranged around the outer peripheral side of the subcontracting rotating wheel. The vertical distance between the upper end of the arc-shaped pipe and the axis of the subcontracting rotating wheel is L, the outer diameter of the subcontracting rotating wheel is D, and L ≤ 0.5D. The lower end of the arc-shaped pipe is located directly below the subcontracting rotating wheel.

[0007] In the above supply mechanism for continuous-row items, the support rod includes a material receiving section and a guiding section. The air pipe and the baffle are both located above the material receiving section. One end of the guiding section is connected to the material receiving section, and the other end extends downward and obliquely along the conveying direction.

[0008] In the above supply mechanism for continuous-row items, the distance between the material receiving section and the baffle gradually decreases along the conveying direction.

[0009] In the above supply mechanism for continuous-row items, the brush includes a first brush and a second brush. The first brush contacts the end of the material receiving section, and the second brush contacts the guiding section.

[0010] In the above supply mechanism for continuous-row items, the supply mechanism further includes a pressing rod extending along the conveying direction. The pressing rod is located above the receiving groove. The pressing rod includes a pressing section and a limiting section. The pressing section is arranged parallel to the guiding section. The upper end of the pressing section is located above the lower end of the guiding section. The limiting section is connected to the lower end of the pressing section and extends horizontally along the conveying direction.

[0011] In the above-mentioned supply mechanism for row of articles, the supply mechanism further comprises a spring stopper, one end of which is connected to the baffle plate, and the other end of which extends downward to level the row of articles on the support rod to be perpendicular to the conveying direction.

[0012] In the above-mentioned supply mechanism for row-by-row articles, the number of the baffles is plural, and the outer peripheral side of the subpackaging wheel is axially spaced with a plurality of the avoidance grooves, and the number of the baffles is equal to the number of the avoidance grooves.

[0013] In the above-mentioned supply mechanism for row-by-row articles, the supply mechanism comprises a plurality of support rods arranged in parallel and at intervals, and a plurality of scrapers are provided on the conveying block, and the scrapers pass through the gaps between two adjacent support rods.

[0014] Beneficial effects of the present invention:

[0015] After the cutter in the present invention cuts off the row of articles, as the packaging wheel rotates, the row of articles will abut against the baffle plate, so that the articles embedded in the grooves can be pried out one by one through the baffle plate. At the same time, the air pipe of the blowing mechanism will blow air in the direction of the baffle plate, so as to blow the articles that have been lifted out to make them stick to the lower side of the baffle plate and put them in a stretched state. In this way, when all the articles in the row of articles are pried out of the grooves, the row of articles can fall on the support rod in a flat state, and then move along the conveying direction under the push of the scraper. After abutting against the brush, the row of articles will curl up under the obstruction of the brush, and finally pass through the brush and fall into the receiving groove of the conveying block in a curled state. During the insertion process of the packaging box, the ends of the curled row of articles are not easy to disperse after losing the restraint of the conveying block, thereby avoiding the problem of being blocked by the beverage and unable to be inserted into the gap, thereby avoiding the phenomenon of missing the row of articles. The air pipe is an arc-shaped pipe arranged around the outer circumference of the sub-packaging wheel. The vertical distance between the upper end of the arc-shaped pipe and the axis of the sub-packaging wheel is L, the outer diameter of the sub-packaging wheel is D, L≤0.5D, and the lower end of the arc-shaped pipe is located directly below the sub-packaging wheel. With such a design, the lower limit of the row of objects can be achieved through the air pipe, so that the row of objects can be located in the groove before reaching the baffle, avoiding the cut end of the row of objects from escaping from the groove in advance under special circumstances, resulting in the inability to fall on the support rod in a flat state; in addition, the lower end of the arc-shaped pipe is located directly below the sub-packaging wheel, which allows the wind blown out of the air pipe to flow horizontally to avoid the wind from affecting the row of objects falling on the support rod, thereby ensuring the flat state of the row of objects on the support rod.

[0016] The support rod includes a receiving section and a guiding section, the air pipe and the baffle are both located above the receiving section, one end of the guiding section is connected to the receiving section, and the other end extends downward along the conveying direction. With such a design, the curled row of articles can fall smoothly into the receiving groove through the guidance of the guiding section.

[0017] The distance between the material receiving section and the baffle gradually decreases along the conveying direction. With such a design, the continuous items can be wound more tightly, facilitating their subsequent insertion into the packaging box.

[0018] The brush includes a first brush and a second brush. The first brush contacts the end of the material receiving section, and the second brush contacts the guiding section. With such a design, the winding effect of the brush on the continuous items can be enhanced, ensuring that the continuous items fall into the receiving groove in a curled state.

[0019] The supply mechanism further includes a pressing rod extending along the conveying direction. The pressing rod is located above the receiving groove and includes a pressing section and a limiting section. The pressing section is arranged parallel to the guiding section, with the upper end of the pressing section above the lower end of the guiding section. The limiting section is connected to the lower end of the pressing section and extends horizontally along the conveying direction. With such a design, the curled continuous items can be pressed into the receiving groove by the pressing section, preventing local dispersion during the process of falling into the receiving groove; while the limiting section can prevent the continuous items falling into the receiving groove from popping out upwards, facilitating their subsequent insertion into the packaging box.

[0020] There are multiple baffles. A plurality of avoidance grooves are axially spaced on the outer peripheral side of the subcontracting runner, and the number of baffles is equal to the number of avoidance grooves. With such a design, it is easier for the baffle to pry the items out of the groove.

[0021] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

The packaging wheel 200, the first driving mechanism 600 and the second driving mechanism 700 are all rotatably mounted on the mounting plate 100. The first driving mechanism 600 is a first motor for driving the packaging wheel 200 to rotate. The second driving mechanism 700 drives the cutter 300 to reciprocate radially along the packaging wheel 200. The second driving mechanism 700 is a prior art and will not be described in detail herein. A plurality of grooves 210 and cutting grooves 220 are provided on the circumference of the subpackaging wheel 200, and the cutting groove 220 is located between two adjacent grooves 210. A guide roller 110 is provided on the mounting plate 100, and the row of objects is wound around the guide roller 110 and then wound on the subpackaging wheel 200. The row of objects in this embodiment may be a row of straws or a row of folding spoons, etc. Taking the row of straws as an example, the row of straws is wound on the subpackaging wheel 200 so that each straw is embedded in the groove 210 in turn, that is, one straw is embedded in each groove 210. In a reciprocating stroke of the cutter 300, the counting of the straws can be achieved by controlling the rotation angle of the subpackaging wheel 200. When the second driving mechanism 700 drives the cutter 300 to cut into the cutting groove 220, the cutter 300 can cut two packaging bags. , and a plurality of support rods 400 are arranged in parallel and spaced apart and are located below the subcontracting wheel 200, the support rods 400 extend along the conveying direction to receive the fallen row of straws, the conveying block 500 is installed on the conveying device and moves along the conveying direction, the conveying block 500 includes a receiving groove 510 and a plurality of scrapers 520, the scraper 520 passes through the gap between two adjacent support rods 400, and the conveying device 01 drives the conveying block 500 to move, and the scraper 520 can scrape the row of straws on the support rods 400 into the receiving groove 510, wherein the conveying device 01 includes a conveyor belt 010 extending along the conveying direction, and the conveying block 500 is installed on the conveyor belt 010, so that the movement of the conveyor belt 010 drives the conveying block 500 to move along the conveying direction.

[0031] In addition, the supply mechanism in this preferred embodiment also includes a blower mechanism 800, a baffle 900 and a brush 1000, wherein the baffle 900 and the brush 1000 are both located above the support rod 400, and a plurality of annular avoidance grooves 230 are also provided on the outer peripheral side of the subpackaging wheel 200, the depth of the avoidance groove 230 is greater than the depth of the groove 210, the number of baffles 900 is equal to the number of avoidance grooves 230, the upper end of the baffle 900 is inserted into the avoidance groove 230, the lower end of the baffle 900 is located outside the avoidance groove 230 and extends along the conveying direction, the brush 1000 is arranged near the lower end of the baffle 900 and contacts the support rod 400, the blower mechanism 800 includes an air pipe 810 and a fan for conveying air to the air pipe 810, the air pipe 810 is located below the cutter 300, and the air outlet of the air pipe 810 is open toward the baffle 900 to blow the cut row of objects off the subpackaging wheel 200. By providing a plurality of baffles 900 , the baffles 900 can more easily pry the straw out of the groove 210 .

[0032] After the second driving mechanism 700 in the preferred embodiment drives the cutter 300 to cut off the row of articles, as the subpackaging wheel 200 rotates, the row of straws will abut against the baffle 900, so that the straws embedded in the grooves 210 can be pried out one by one through the baffle 900. At the same time, the air pipe 810 will blow air toward the baffle 900 to blow the lifted straws to make them stick to the lower side of the baffle 900 and put them in a stretched state. In this way, when all the straws in the row of straws are pried out of the grooves 210, the row of straws can be laid flat. The straws fall onto the support rod 400 and then move along the conveying direction under the push of the scraper 520. After they collide with the brush 1000, they are blocked by the brush 1000 and curled up. Finally, they pass through the brush 1000 and fall into the receiving groove 510 of the conveying block 500 in a curled state. During the insertion into the packaging box, the ends of the curled straws are not easy to spread out after losing the restraint of the conveying block 500, thereby avoiding the problem of being blocked by the beverage and unable to be inserted into the gap, thereby avoiding the phenomenon of missing the insertion of the row of items. Specifically, the air pipe 810 in the preferred embodiment is an arc-shaped tube arranged around the outer peripheral side of the sub-packaging wheel 200, the vertical distance between the upper end of the arc-shaped tube and the axis of the sub-packaging wheel is L, the outer diameter of the sub-packaging wheel 200 is D, L≤0.5D, and the lower end of the arc-shaped tube is located directly below the sub-packaging wheel 200. With such a design, the lower limit of the row of straws can be achieved through the air pipe 810, so that the row of straws can be located in the groove 210 before reaching the baffle 900, thereby preventing the cut end of the row of straws from escaping from the groove 210 in advance under special circumstances, resulting in the inability to fall on the support rod 400 in a flat state; in addition, the lower end of the arc-shaped tube is located directly below the sub-packaging wheel 200, so that the wind blown out by the air pipe 810 can flow horizontally, so as to prevent the wind from affecting the row of straws falling on the support rod 400, thereby ensuring the flat state of the row of straws on the support rod 400.

[0033] In this preferred embodiment, the support rod 400 includes a material receiving section 410 and a guiding section 420. The air pipe 810 and the baffle 900 are both located above the material receiving section 410. The distance between the material receiving section 410 and the baffle 900 gradually decreases along the conveying direction, so that the continuous straws are wound more tightly, which is convenient for later insertion into the packaging box. One end of the guiding section 420 is connected to the material receiving section 410, and the other end extends downward and obliquely along the conveying direction. The brush 1000 includes a first brush 1010 and a second brush 1020. The first brush 1010 contacts the end of the material receiving section 410, and the second brush 1020 contacts the guiding section 420. With such a design, the winding effect of the brush 1000 on the continuous straws can be increased, so as to ensure that the continuous straws fall into the receiving groove 510 in a curled state. In addition, the curled continuous straws can be smoothly guided into the receiving groove 510 through the guiding of the guiding section 420.

[0034] Secondly, the supply mechanism in this preferred embodiment further includes a plurality of pressing rods 1100 that extend along the conveying direction and are arranged at intervals. The pressing rods 1100 are located above the receiving groove 510. The scraping plate 520 passes through the gap between two adjacent pressing rods 1100. The pressing rod 1100 includes a pressing section 1110 and a limiting section 1120. The pressing section 1110 is arranged in parallel with the guiding section 420. The upper end of the pressing section 1110 is located above the lower end of the guiding section 420, and the lower end of the pressing section 1110 is located below the guiding section 420. The limiting section 1120 is connected to the lower end of the pressing section 1110 and extends horizontally along the conveying direction. With such a design, the curled continuous straws can be pressed into the receiving groove 510 through the pressing section 1110, avoiding the phenomenon of partial dispersion during the process of falling into the receiving groove 510. The limiting section 1120 can prevent the continuous straws falling into the receiving groove 510 from slipping out upward, which is convenient for later insertion into the packaging box.

[0035] Finally, in order to prevent the inclined continuous straws from falling off the support rod 400 during the pushing process by the scraping plate 520 on the support rod 400, the supply mechanism in this preferred embodiment further includes a plurality of spring retaining pieces 1200 that are arranged in parallel and at intervals. One end of the spring retaining piece 1200 is fixedly connected to the baffle 900, and the other end extends downward to the material receiving section 410 and is located between the brush 1000 and the subcontracting runner 200, so as to flatten the continuous straws on the support rod 400 perpendicular to the conveying direction, avoiding the continuous straws from falling off the support rod 400 when being pushed by the scraping plate 520 in an inclined state.

[0036] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes not only the content described in the drawings and the above specific embodiments.
