Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a paper separation device and feeding equipment. Background Art

[0002] When packaging prefilled syringes, they need to be covered with Tyvek paper in the nest box. Tyvek paper is relatively thin and has strong air permeability. When sucking up the paper, there is a situation where multiple sheets of paper are sucked up at one time, resulting in paper waste.

[0003] The prior art discloses a moisture-proof paper delivery device, which uses multiple suction cups of equal height to absorb paper. When in use, a pressure plate on the device is pressed on the stacked paper sheets to be picked up, and a nozzle is close to the edge of the picked up paper sheet. Air is blown to separate the top surface of the paper sheet to be picked up from the paper sheet below, and then the suction cup absorbs the top surface of the paper sheet to be picked up, thereby realizing the function of sucking a single sheet of paper.

[0004] However, the above separation method is not suitable for thinner Tyvek paper with static electricity, that is, after the nozzle jets, the two topmost sheets of Tyvek paper cannot be effectively separated, and it is very likely that multiple sheets of Tyvek paper on the upper layer will be separated from the Tyvek paper on the lower layer, making it difficult to ensure that only one sheet of Tyvek paper is sucked each time. Utility Model Content

[0005] The utility model aims to provide a paper separation device and feeding equipment, which are suitable for thinner Tyvek paper with static electricity and can easily ensure that only one piece of Tyvek paper is sucked each time.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] In the first aspect, the utility model provides a paper separation device, comprising a bracket, a material picking suction head assembly, a separation suction head assembly and a blowing nozzle assembly, wherein the material picking suction head assembly, the separation suction head assembly and the blowing nozzle assembly are sequentially installed on the bracket from the middle of the bracket to the periphery, and the separation adsorption surface of the separation suction head assembly is higher than the material picking adsorption surface of the material picking suction head assembly, and the separation adsorption surface corresponds to the edge of the paper.

[0008] When the above-mentioned paper separation device is working, the bracket drives the material picking suction head assembly, the separation suction head assembly and the blowing nozzle assembly to move downward. After the material picking suction head assembly contacts the topmost paper, the material picking suction head assembly sucks the paper, and at the same time, the separation suction head assembly sucks the edge of the paper. Since the separation adsorption surface of the separation suction head assembly is higher than the material picking adsorption surface of the material picking suction head assembly, under the adsorption force of the separation suction head assembly, the edge of the paper in the box will be lifted up, and the blowing nozzle assembly blows air towards the edge of the paper that has been sucked to eliminate static electricity and realize the separation of the paper.

[0009] Compared with the prior art, the paper separation device provided by the utility model can make the edge of the paper curl up through the cooperation of the material taking suction head assembly and the separation suction head assembly, and the blowing nozzle assembly can separate the sucked up paper more specifically. Since the edge of the sucked up paper has been curled up, the gas sprayed by the blowing nozzle assembly can easily enter the contact surface of the edge of the adjacent paper and pass through between the adjacent papers, quickly eliminating the static electricity between the adjacent papers. It is suitable for thinner Tyvek paper with static electricity, and it is easy to ensure that only one piece of Tyvek paper is sucked up each time.

[0010] Furthermore, the separation suction head assembly comprises at least one separation adsorption surface, and the separation adsorption surface gradually increases in height along the direction pointing from the middle of the bracket to the periphery.

[0011] The height of the separation adsorption surface gradually increases from the middle of the bracket to the periphery, so that when the separation adsorption surface absorbs paper, the edge of the paper close to the middle of the bracket will not be lifted up a large distance under the action of suction. The edge of the paper will be lifted up smoothly, and the fit with the separation adsorption surface will be better, reducing the pulling on the surrounding paper and playing a certain protective role for the paper.

[0012] Further, the separation suction head assembly includes at least one separation suction head, the bottom end of the separation suction head has the separation suction surface, and the separation suction surface corresponds to the corner of the paper.

[0013] Compared with other parts of the paper, the corners of the paper are more likely to be lifted up by suction and separated from the underlying paper.

[0014] Furthermore, the separation suction head assembly includes four separation suction heads, and the separation adsorption surfaces on the four separation suction heads correspond to the four corners of the paper one by one.

[0015] The above arrangement can realize the warping of the four corners, making it easier to separate adjacent papers.

[0016] Furthermore, the position of each separation suction head relative to the bracket is adjustable along a direction pointing from the middle of the bracket to the periphery.

[0017] The above arrangement allows the position of the separation adsorption surface on each separation suction head to be adjustable relative to the paper, thereby adapting to papers of different sizes.

[0018] Furthermore, the blowing nozzle assembly comprises at least one blowing port, and the height of the blowing port is located between the separation adsorption surface and the material taking adsorption surface.

[0019] In this way, the air blown out of the air port can more smoothly enter between the paper adsorbed by the separation adsorption surface and the next adjacent paper, thereby eliminating the static electricity between the two.

[0020] Furthermore, the blowing nozzle assembly includes at least one blowing nozzle, and the blowing nozzle and the separation suction head are arranged one by one opposite to each other along the direction from the middle of the bracket to the periphery.

[0021] The above arrangement enables the gas blown out of the blowing nozzle to quickly reach the edge of the paper sucked by the separation suction head.

[0022] Furthermore, the position of each of the blowing nozzles is adjustable relative to the bracket in the height direction.

[0023] The height of the air outlet on each blowing nozzle relative to the paper can be adjusted to adapt to the paper with different warping heights.

[0024] Furthermore, the bracket includes a bracket body and a plurality of extension arms connected to the bracket body, and the plurality of extension arms are distributed in a scattered manner relative to the bracket body;

[0025] The material taking suction head assembly is installed on the bracket body, and the separation suction head assembly and the blowing nozzle assembly are installed on each of the extension arms.

[0026] The above arrangement facilitates the installation of the material taking suction head assembly, the separation suction head assembly and the blowing nozzle assembly.

[0027] In a second aspect, the utility model further provides a feeding device, comprising a mechanical arm and a paper separation device as described in the above scheme, wherein the bracket is installed at the end of the mechanical arm.

[0028] The feeding device provided in the second aspect of the utility model has the paper separation device provided in the first aspect of the utility model, and thus has all the beneficial effects of the paper separation device provided in the first aspect of the utility model.

DETAILED DESCRIPTION

[0035] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0039] The first aspect of the present invention provides a paper separation device. Figures 1 to 3 As shown, it includes a bracket 1, a material picking suction head assembly 2, a separation suction head assembly 3 and a blowing nozzle assembly 4. The material picking suction head assembly 2, the separation suction head assembly 3 and the blowing nozzle assembly 4 are installed on the bracket 1 in sequence from the middle of the bracket 1 to the periphery. The separation adsorption surface 311 of the separation suction head assembly 3 is higher than the material picking adsorption surface 211 of the material picking suction head assembly 2, and the separation adsorption surface 311 corresponds to the edge of the paper.

[0040] When the paper separation device provided in the above embodiment is in use, the bracket 1 drives the material taking suction head assembly 2, the separation suction head assembly 3 and the blowing nozzle assembly 4 to move downward together. Figure 1 As shown, the picking suction head assembly 2 will preferentially contact the topmost paper, and the picking suction head assembly 2 will suck the paper. At the same time, the separation suction head assembly 3 will suck the edge of the paper. Since the separation suction surface 311 of the separation suction head assembly 3 is higher than the picking suction surface 211 of the picking suction head assembly 2, under the adsorption force of the separation suction head assembly 3, the edge of the paper in the box will be lifted up, and the blowing nozzle assembly 4 will blow air toward the edge of the paper that has been sucked to eliminate the static electricity between the two adjacent papers and realize the separation of the papers.

[0041] The paper separation device provided in the above embodiment can make the edge of the paper curl up through the cooperation of the material taking suction head assembly 2 and the separation suction head assembly 3, so that the gas sprayed by the blowing nozzle assembly 4 can easily enter the contact surface of the edge of adjacent papers and pass through between adjacent papers, quickly eliminating the static electricity between adjacent papers. The paper separation device provided in the above embodiment is suitable for thinner Tyvek paper with static electricity, and it is easy to ensure that only one piece of Tyvek paper is sucked each time.

[0042] The separation suction head assembly 3 may include only one separation suction surface 311 , or may include multiple separation suction surfaces 311 .

[0043] When the separation suction head assembly 3 includes only one separation suction surface 311, the separation suction surface 311 may correspond to only one corner of the edge of the paper, or may correspond to multiple corners of the edge of the paper, and the suction surface may be circular, square or triangular. Of course, the suction surface may also be annular and correspond to the entire edge of the paper.

[0044] When the separation suction head assembly 3 includes a plurality of separation suction surfaces 311 , each separation suction surface 311 may correspond to a corner of an edge of the paper, and the separation suction surface 311 may be circular, square or triangular.

[0045] It should be noted that the number and shape of the separation and adsorption surfaces 311 are not limited to the above examples, and any separation and adsorption surface 311 that can adsorb the edge of the paper can be used.

[0046] In an optional embodiment, if Figure 2 As shown, there are four separation adsorption surfaces 311 , all of which are circular, and the four separation adsorption surfaces 311 correspond to the four corners of the paper one by one.

[0047] In an optional embodiment, if Figure 1 As shown, the separation adsorption surface 311 gradually increases in height from the middle of the bracket 1 toward the periphery.

[0048] If the height of the separation adsorption surface 311 along the direction from the middle of the bracket 1 to the periphery remains unchanged, then there will be a large height difference between the separation adsorption surface 311 and the material taking adsorption surface 211 at all locations. When sucking paper, the part of the edge of the paper close to the middle of the bracket 1 will also be lifted up a large distance under the action of suction, increasing the pulling of the surrounding paper.

[0049] The height of the separation adsorption surface 311 gradually increases from the middle of the bracket 1 to the periphery, so that when the separation adsorption surface 311 absorbs paper, the edge of the paper close to the middle of the bracket 1 will not be lifted up a large distance under the action of suction. The edge of the paper will be lifted up smoothly, and the fit with the separation adsorption surface 311 will be better, reducing the pulling on the surrounding paper and playing a certain protective role for the paper.

[0050] Of course, in an optional embodiment, the height of the separation adsorption surface 311 along the direction from the middle of the bracket 1 to the periphery may also remain unchanged.

[0051] In an optional embodiment, if Figure 2 As shown, the separation suction head assembly 3 includes at least one separation suction head 31. The bottom end of the separation suction head 31 has a separation suction surface 311, and the separation suction surface 311 corresponds to the corner of the paper.

[0052] Compared with other parts of the paper, the corners of the paper are more likely to be lifted up by suction and separated from the underlying paper.

[0053] Each separation suction head 31 can form negative pressure at the separation suction surface 311 , thereby sucking the corners of the paper.

[0054] The separation tip assembly 3 includes one, two, three, four or five separation tips 31 , the number of which can be selected according to actual needs.

[0055] In an optional embodiment, if Figure 2 As shown, the separation suction head assembly 3 includes four separation suction heads 31, and the separation adsorption surfaces 311 on the four separation suction heads 31 are arranged opposite to the four corners of the paper one by one, so as to achieve the lifting of the four corners and make it easier to separate adjacent papers.

[0056] In an optional embodiment, if Figure 4As shown, the position of each separation suction head 31 relative to the bracket 1 along the direction pointing from the middle of the bracket 1 to the periphery is adjustable, so that the position of the separation adsorption surface 311 on each separation suction head 31 relative to the paper is adjustable, thereby adapting to papers of different sizes.

[0057] Specifically, a first waist-shaped hole 13 is provided on the bracket 1, and the first waist-shaped hole 13 extends from the middle of the bracket 1 to the periphery. Bolts and other connecting parts can be connected to the separation suction head 31. The connecting parts can pass through the first waist-shaped hole 13 and be locked by nuts. Loosening the nuts can adjust the position of the separation suction head 31 relative to the first waist-shaped hole 13.

[0058] Of course, other structures can also be used between the bracket 1 and the separation suction head 31 to adjust the position of the separation suction head 31. For example, the bracket 1 is provided with multiple slots along the direction from the middle part to the periphery, and the separation suction head is provided with a card block that can be inserted into any of the slots.

[0059] In an optional embodiment, if Figure 4 As shown, the bracket 1 includes an inclined portion 14 gradually extending upward from the middle of the bracket 1 to the periphery, and the separation suction head 31 is connected to the inclined portion 14, and the position of the separation suction head 31 relative to the bevel portion 14 along the direction from the middle of the bracket 1 to the periphery is adjustable.

[0060] The above arrangement enables the separation suction head 31 to change its height while adjusting inward and outward. For example, for a larger paper, the contact surface between the papers is larger, and the separation suction head 31 can be adjusted outward. After the adjustment, the height of the separation suction surface 311 is higher, the paper warps more, and it is easier to separate the papers. For a smaller paper, the separation suction head 31 is adjusted inward. After the adjustment, the height of the separation suction surface 311 is lower, which reduces the warping degree of the paper and reduces the probability of damage to the paper during the warping process.

[0061] It can be understood that outward and inward are relative to the center of the bracket 1. Moving closer to the center of the bracket 1 is inward, and moving away from the center of the bracket 1 is outward.

[0062] In an optional embodiment, if Figure 4 As shown, a first waist-shaped hole 13 is provided on the inclined portion 14 .

[0063] In an optional embodiment, the blowing nozzle assembly 4 includes one, two, three, four or five blowing ports 411, and the number can be selected according to actual needs.

[0064] like Figure 2 As shown, the blowing nozzle assembly 4 includes four blowing ports 411, and the four blowing ports 411 are arranged opposite to the four corners of the paper.

[0065] In an optional embodiment, the height of the air outlet 411 is located between the separation adsorption surface 311 and the material collection adsorption surface 211, so that the gas blown out of the air outlet 411 can more smoothly enter between the paper adsorbed by the separation adsorption surface 311 and the next adjacent paper, eliminating the static electricity between the two.

[0066] In an optional embodiment, the mouthpiece assembly 4 includes one, two, three, four or five mouthpieces 41 .

[0067] like Figure 2 As shown, when the mouthpiece assembly 4 includes four blowing ports 411 , the mouthpiece assembly 4 correspondingly includes four mouthpieces 41 , and each mouthpiece 41 has one blowing port 411 .

[0068] In an optional embodiment, if Figure 2 As shown, in order to enable the gas blown out of the blowing nozzle 41 to quickly reach the edge of the paper sucked by the separation suction head 31, the blowing nozzle 41 and the separation suction head 31 are arranged one by one opposite to each other along the direction pointing from the middle of the bracket 1 to the periphery.

[0069] On the basis of the above embodiment, when the bracket 1 includes an extension arm 12 , the blowing nozzle 41 and the separation suction head 31 can be arranged on one extension arm 12 .

[0070] In an optional embodiment, the position of each blowing nozzle 41 is adjustable relative to the bracket 1 in the height direction, so that the height of the blowing port 411 on each blowing nozzle 41 is adjustable relative to the paper, thereby adapting to papers with different warping heights.

[0071] Specifically, a second waist-shaped hole 15 is opened on the bracket 1, and the second waist-shaped hole 15 extends in the vertical direction. The mouthpiece 41 can be connected to a connecting piece such as a bolt. The connecting piece can pass through the second waist-shaped hole 15 and be locked by a nut. The height of the mouthpiece 41 relative to the second waist-shaped hole 15 can be adjusted by loosening the nut.

[0072] Of course, other structures may be used between the bracket 1 and the mouthpiece 41 to adjust the position of the mouthpiece 41. For example, the bracket 1 is provided with a plurality of slots along the vertical direction, and the mouthpiece 41 is provided with a block that can be inserted into any of the slots.

[0073] In an optional embodiment, when the bracket 1 includes an extension arm 12 , a second waist-shaped hole 15 is provided at one end of the extension arm 12 away from the middle of the bracket 1 .

[0074] In an optional embodiment, if Figure 2 As shown, in order to facilitate the installation of the material taking suction head assembly 2, the separation suction head assembly 3 and the blowing nozzle assembly 4, the bracket 1 includes a bracket body 11 and a plurality of extension arms 12 connected to the bracket body 11, and the plurality of extension arms 12 are scattered relative to the bracket body 11, wherein:

[0075] The material taking suction head assembly 2 may include a plurality of material taking suction heads 21, and the plurality of material taking suction heads 21 are installed on the bracket body 11, that is, the material taking suction heads 21 are located at the innermost side;

[0076] A separation suction head assembly 3 and a blowing nozzle assembly 4 are mounted on each extension arm 12 , and the blowing nozzle assembly 4 is located outside the separation suction head assembly 3 .

[0077] In addition, one end of the extension arm 12 close to the bracket body 11 is an inclined portion 14 , and the inclined portion 14 is connected to the bracket body 11 .

[0078] The embodiment of the second aspect of the utility model is to provide a feeding device. The feeding device provided by the embodiment of the second aspect of the utility model includes a robot and the above-mentioned paper separation device. The bracket 1 is installed at the end of the robot, and the robot drives the bracket 1 to move.

[0079] The feeding device provided in the second aspect of the utility model has the paper separation device provided in the embodiment of the first aspect of the utility model, and thus has all the beneficial effects of the paper separation device provided in the embodiment of the first aspect of the utility model.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
