Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the technical field of automated production, and particularly to a material separating device, a material separating system and a material separating method. Background Art
[0002] In the process of automated production, the production process of materials is usually relatively fast. After the materials are produced, they will be conveyed forward one by one on the conveyor line. Due to the small distance between the materials, this will make it difficult for subsequent processes such as automatic detection, clamping, and film pasting on the production line, thus affecting the overall production efficiency of the production line.
[0003] Currently, mainly by setting a material separating device on the conveyor line, the material separating device is used to prevent the subsequent material from advancing. Until the previous material has advanced a certain distance, the subsequent material is then released, so as to form a certain interval between the two materials, thereby separating the materials on the conveyor line. However, such a way of directly preventing the materials from advancing to separate the materials will cause serious blockage of the materials located upstream of the material separating device, and problems such as dumping and extrusion are likely to occur. Summary of the Invention
[0004] In view of the above problems, the embodiments of the present application provide a material separating device, a material separating system and a material separating method, which are used to solve the problems that when separating materials in the prior art, the materials located upstream of the material separating device will be seriously blocked and are prone to dumping and extrusion.
[0005] According to one aspect of the embodiments of the present application, a material separating device is provided. The material separating device includes: a base and a material separating mechanism; the material separating mechanism is arranged on the base, and the base is used to fix the material separating mechanism on one side of the conveyor line; the material separating mechanism includes a screw rod and a driving member. The screw rod is rotationally connected to the base, and the driving member is fixedly arranged on the base and connected to the screw rod. The driving member is used to drive the screw rod to rotate; the screw rod is configured to be parallel to the conveying direction of the conveyor line. The screw rod has a spiral part protruding above the conveyor line. The screw rod is used to limit the moving speed of the materials on the conveyor line at the position of the material separating mechanism when rotating, so that the moving speed of the materials is less than the conveying speed of the conveyor line, thereby forming a predetermined interval between the materials located downstream of the material separating mechanism on the conveyor line.
[0006] In an optional manner, the screw rod is used to abut against the material through the spiral part when stationary to prevent the material from moving along the conveyor line.
[0007] In an optional manner, the screw rod has at least two turns of spiral parts to limit the moving speeds of at least two materials.
[0008] In an alternative manner, a rotatable connection seat is movably arranged on the base, and the screw rod is rotatably connected to the rotatable connection seat; an adjustment mechanism is movably arranged on the base, and the adjustment mechanism is connected to the rotatable connection seat. The adjustment mechanism is used to drive the rotatable connection seat and the screw rod to move relative to the base along the adjustment direction when moving, so as to adjust the protruding distance of the spiral part above the conveyor line. Wherein, the adjustment direction is perpendicular to the extending direction of the screw rod.
[0009] In an alternative manner, the adjustment mechanism includes a lead screw and a nut fixing seat. The lead screw is rotatably connected to the base, and the rotatable connection seat is fixedly connected to the nut fixing seat. The nut fixing seat is used to drive the rotatable connection seat and the screw rod to move along the adjustment direction when the lead screw rotates.
[0010] In an alternative manner, the nut fixing seat is located at the middle position of the rotatable connection seat; the adjustment mechanism further includes guide rails respectively located on both sides of the lead screw and sliders slidably connected to the guide rails. The guide rails are arranged on the base and are parallel to the lead screw, and the sliders are fixedly connected to the rotatable connection seat. The sliders are used to slide relative to the guide rails when the rotatable connection seat moves along the adjustment direction.
[0011] According to another aspect of the embodiments of the present application, a material distribution system is provided, including a conveyor line and the material distribution device described in any one of the above. The conveyor line is used to transport materials, and the material distribution device is fixedly arranged on one side of the conveyor line; the material distribution device is used to limit the moving speed of the materials on the conveyor line at the position of the material distribution device, so that the moving speed of the materials is less than the conveying speed of the conveyor line, thereby forming a predetermined interval between the materials on the conveyor line downstream of the material distribution device.
[0012] In an alternative manner, at least three sensing devices are arranged at intervals at the position downstream of the material distribution device on the conveyor line, and the distance between two adjacent sensing devices is equal to the width of the material. The at least three sensing devices are used to detect whether there are materials at the corresponding positions on the conveyor line; the material distribution system further includes a control device, and the control device is respectively in signal connection with the sensing devices and the driving member of the material distribution device. The control device is used to control the driving member to close when at least three sensing devices all detect materials, so that the screw rod stops and abuts against the materials through the spiral part thereon to prevent the materials from moving along the conveyor line.
[0013] According to another aspect of the embodiments of the present application, a material distribution method is provided, which is applied to the material distribution system described in any one of the above. The method includes: obtaining the width of the material and the required spacing between two adjacent materials; determining the sum of the width and the spacing as the first distance that the material moves when being conveyed by the conveying line during one rotation of the screw rod; obtaining the conveying speed of the conveying line, and determining the ratio between the first distance and the conveying speed of the conveying line as the time required for one rotation of the screw rod; obtaining the pitch of the spiral part on the screw rod, and determining the ratio between the pitch and the time as the conveying speed on the surface of the screw rod; obtaining the parameters of the screw rod, and determining the rotation speed of the screw rod according to the conveying speed on the surface of the screw rod and the parameters; controlling the driving member to work and driving the screw rod to rotate at the rotation speed.
[0014] In an optional manner, at least three sensing devices are arranged at intervals at a position on the conveying line downstream of the material distribution device, and the distance between two adjacent sensing devices is equal to the width of the material; the method further includes: detecting whether there is material at the corresponding position on the conveying line through at least three sensing devices; if at least three sensing devices all detect the material, controlling the driving member to close, so that the screw rod stops and the spiral part on it abuts against the material to prevent the material from moving along the conveying line.
[0015] In the embodiments of the present application, the movement speed of the material is restricted by the spiral part on the screw rod, so that the movement speed of the material at the screw rod is less than the conveying speed of the conveying line. Thus, after the material passes through the screw rod, a predetermined interval is automatically formed between the front and rear materials, which can not only reduce the difficulty of subsequent processes and improve the overall production efficiency of the production line, but also enable the material to move at a relatively low speed at the material distribution device instead of completely stopping, effectively avoiding problems such as dumping and extrusion due to serious blockage of the material located upstream of the material distribution device.

The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

[0040] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installation", "connection", "linkage", "fixation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can also be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.
[0041] The core of automated production is to automatically complete tasks such as material processing, assembly, inspection, and packaging through technologies such as computers, robots, sensors, and control systems, and it is widely used in multiple industries such as food, medicine, chemical industry, and logistics. Automated production mainly transports materials through conveyor lines such as conveyor belts, roller conveyors, and chain conveyors, and then processing equipment, inspection equipment, etc. perform operations such as processing, inspection, and packaging on the materials on the conveyor line.
[0042] However, due to the relatively fast production process of materials, materials usually move on the conveyor line one after another in close proximity. Taking plastic bottles as an example, plastic bottles are widely used in life. Laundry detergents, dishwashing liquids, etc. all use injection-molded plastic bottles to fill liquids. During the production process of such plastic bottles, after the bottle bodies of the plastic bottles are produced by the injection molding machine, they will enter the subsequent conveyor line one after another in close proximity. When subsequent operations such as automated inspection, clamping, and film pasting of plastic bottles are required on the conveyor line, due to the small distance between plastic bottles, it will increase the difficulty of subsequent production processes and affect the overall production efficiency of the production line.
[0043] In order to reduce the difficulty of subsequent production processes and improve the overall production efficiency of the production line, a material separation device can be set on the conveyor line, and the materials on the conveyor line are separated through the material separation device. Currently, the material separation device mainly separates materials by directly blocking the forward movement of materials. Specifically, after the previous material passes through the material separation device, the material separation device will block the subsequent material to prevent the subsequent material from continuing to move forward. After the previous material has moved forward a certain distance, the subsequent material is released, so as to form a certain interval between the previous material and the subsequent material. However, in this way of separating materials, all the materials located upstream of the material separation device will stop moving forward, which will not only cause serious blockages, but also easily cause problems such as dumping and extrusion due to the continuous operation of the conveyor line, thereby causing damage to the materials.
[0044] Based on this, in order to prevent serious blockage of the materials located upstream of the material distribution device, the present application provides a material distribution device, which adopts the form of a screw rod to buffer the conveying speed of the materials, and will not completely stop the materials. That is, at the same time, the moving distance of the materials blocked by the spiral part on the conveying line will be less than that of the materials located downstream of the screw rod. At this time, a certain interval will be formed between the materials blocked by the screw rod and the materials located downstream of the material distribution device. This method separates the two materials by slowing down the moving speed of the latter material, and it will not completely stop the materials upstream of the material distribution device, thereby avoiding problems such as dumping and extrusion of the materials upstream of the material distribution device due to serious blockage, and realizing smooth separation of the materials.
[0045] According to one aspect of the embodiments of the present application, a material distribution device is provided, as Figure 1 , Figure 2 and Figure 3 shown, Figure 1 shows the structural diagram of the material distribution system applying this material distribution device, Figure 2 shows the three-dimensional view of the material distribution device, Figure 3 shows Figure 1 the enlarged view of part A in
[0046] As Figure 1 and Figure 2 shown, the material distribution mechanism 120 includes a screw rod 121 and a driving member 122. The screw rod 121 is rotatably connected to the base 110, and the driving member 122 is fixedly arranged on the base 110 and connected to the screw rod 121. The driving member 122 is used to drive the screw rod 121 to rotate.
[0047] As Figure 1 and Figure 3 shown, the screw rod 121 (the screw rod 121 extends along the direction of the double arrow M in Figure 1 ) is configured to be parallel to the conveying direction of the conveying line 200 (i.e., the direction of the arrow X in Figure 1 ). The screw rod 121 has a spiral part 1211 protruding above the conveying line 200. The screw rod 121 is used to limit the moving speed of the material 300 on the conveying line 200 at the position of the material distribution mechanism 120 when rotating, so that the moving speed of the material 300 is less than the conveying speed of the conveying line 200, thereby forming a predetermined interval between the materials 300 located downstream of the material distribution mechanism 120 on the conveying line 200.
[0048] The base 110 is used to support and fix the material distribution mechanism, as Figure 1 and Figure 3As shown, the base 110 can be a bracket independent of the conveyor line 200. Not only can the feeding device 100 be placed and fixed on one side of the conveyor line 200 through the bracket to quickly complete the installation of the feeding device 100, but also the position of the feeding device 100 can be easily changed through the bracket, improving the flexibility of the feeding device 100. Of course, the base 110 can also be set on the same frame together with the conveyor line 200 to form an integral body, so that the distance between the feeding device 100 and the conveyor line 200 remains stable, thereby enabling the feeding mechanism 120 to stably separate the material 300 on the conveyor line 200.
[0049] The feeding mechanism 120 is the main structure of the feeding device 100 and is used to separate the material 300. Among them, the screw rod 121 is used to separate the material 300 when rotating, and the driving member 122 is used to drive the screw rod 121 to rotate. The driving member 122 can be devices such as a motor or a motor. The output end of the driving member 122 can be connected to the screw rod 121 through transmission devices such as gears, belts and belt pulleys, chains and sprockets to accurately control the rotation speed of the screw rod 121. Of course, it can also be directly connected to the screw rod 121 to reduce the parts of the feeding mechanism 120 and simplify the structure of the feeding mechanism 120.
[0050] As an example, as Figure 1 and Figure 2 shown, the first fixing plate 131 and the second fixing plate 132 can be provided on the base 110. Two synchronous pulleys 123 are provided on the first fixing plate 131, and are connected by a synchronous belt 124 between the two synchronous pulleys 123. One end of the screw rod 121 is connected to one of the synchronous pulleys 123, and the other end is rotatably connected to the second fixing plate 132. The output end of the driving member 122 is connected to the other synchronous pulley 123, so that after the driving member 122 is turned on, the screw rod 121 can be driven to rotate through the two synchronous pulleys 123 and the synchronous belt 124.
[0051] When the material 300 is conveyed by the conveyor line 200 to the position where the screw rod 121 is located, it will abut against the spiral part 1211 on the screw rod 121. When the screw rod 121 is in a rotating state, while the material 300 is abutted by the spiral part 1211, it will also move along with the rotation of the spiral part 1211, so that the moving speed of the material 300 can be restricted by the spiral part 1211. Specifically, as Figure 1 and Figure 3As shown in the figure, it is assumed that the material 300 moves along the direction indicated by arrow X on the conveyor line 200. The extending direction of the screw rod 121 is the direction indicated by the double arrow M, and the direction indicated by the double arrow M is parallel to the direction indicated by arrow X. When the screw rod 121 rotates in the direction indicated by arrow Y, the part of the spiral part 1211 blocking in front of the material Q2 will change in the direction indicated by arrow X. Correspondingly, the material Q2 moves forward slowly with the change of the blocking part on the spiral part 1211, thereby forming a speed difference with the previous material Q1, and then forming an interval.
[0052] Therefore, when the change speed of the part of the spiral part 1211 blocking in front of the material 300 (i.e., the conveying speed of the surface of the screw rod 121 to the material 300) is less than the conveying speed of the conveyor line 200, the moving speed of the material 300 will be restricted by the spiral part 1211, so that the material 300 moves at the conveying speed of the surface of the screw rod 121. At the position where the material distributing mechanism 120 is located, the moving speed of the material 300 will be less than the conveying speed of the conveyor line 200. In the same time, the moving distance of the material 300 on the conveyor line 200 downstream of the material distributing mechanism 120 (i.e., Figure 1 the position below the material distributing mechanism 120 on the conveyor line 200 in the figure) is greater than the moving distance of the material 300 blocked by the spiral part 1211. Specifically, as Figure 3 shown, the material Q1 has passed through the material distributing mechanism 120 and is no longer blocked by the spiral part 1211, while the material Q2 is still in the screw rod 121 and is blocked by the spiral part 1211. At this time, the moving speed of the material Q1 will be greater than the moving speed of the material Q2. When the material Q2 reaches the end of the screw rod 121, the moving distance of the material Q1 is greater than the moving distance of the material Q2. At this time, a predetermined interval will be formed between the material Q2 and the material Q1.
[0053] In addition, considering that the production line also includes subsequent processes such as detecting and packaging the material 300, and abnormal subsequent processes may cause congestion of the materials downstream of the material distributing mechanism 120. In order to avoid the aggravation of congestion, when the screw rod 121 is stationary, it can be in contact with the material 300 through the spiral part to prevent the material 300 from moving along the conveyor line 200. Specifically, when an abnormality occurs in the subsequent process, resulting in congestion of the material 300 on the conveyor line 200 downstream of the material distributing mechanism 120, the driving member 122 can be turned off to stop the rotation of the screw rod 121 and prevent the material 300 from continuing to move downstream of the material distributing mechanism 120, thereby preventing the material 300 from continuously flowing into the downstream and avoiding problems such as dumping and extrusion of the material 300 downstream due to serious congestion.
[0054] Furthermore, in order to improve the material distribution performance of the material distributing mechanism 120, as Figure 3As shown, the screw rod 121 has at least two turns of spiral parts 1211 to limit the moving speeds of at least two materials 300, that is, during the rotation of the screw rod 121, at least two materials 300 are blocked by the spiral parts 1211. For example, as Figure 3 shown, the screw rod 121 has two and a half turns of spiral parts 1211. During the process of separating materials, the screw rod 121 can block two to three materials 300 at the same time to limit the speeds of two to three materials 300. And after the materials 300 enter the screw rod 121, they need to move a relatively long distance to pass through the screw rod 121. This can prevent the poor blocking effect of the screw rod 121 caused by the too-fast moving speed of the materials 300. Especially in a fast production line, it can effectively prevent the situation that there is no predetermined interval between the materials 300 after the materials 300 pass through the screw rod 121 due to the too-fast speed.
[0055] Considering that the heights of the conveyor lines 200 in different production lines may be different, a telescopic mechanism can be arranged on the base 110 to adjust the material distribution device 100 according to the height of the conveyor line 200 to ensure that the height of the screw rod 121 is higher than the height of the conveyor line 200, or adjust the distance between the spiral part 1211 and the conveyor line 200 according to the height of the materials 300, so that the spiral part 1211 can abut against the middle position of the materials 300, ensuring that the materials 300 can be in balanced force and preventing the materials 300 from tilting.
[0056] In the above embodiment, the moving speeds of the materials 300 are limited by the spiral parts 1211 on the screw rod 121, so that the moving speed of the materials 300 at the screw rod 121 is less than the conveying speed of the conveyor line 200. As a result, after the materials 300 pass through the screw rod 121, a predetermined interval is automatically formed between the front and rear materials. This can not only reduce the difficulty of subsequent processes and improve the overall production efficiency of the production line, but also enable the materials 300 to move at a relatively low speed at the material distribution device instead of completely stopping, effectively preventing problems such as dumping and extrusion caused by serious blockage of the materials located upstream of the material distribution device.
[0057] Furthermore, since the sizes of the materials 300 in different production lines may be different, or the widths of the conveyor lines 200 may be different, and the material distribution device 100 can only be fixed on one side of the conveyor line 200 through the base 110, when the materials 300 move on the conveyor line 200, the distances between the materials 300 and the material distribution device 100 may be different. If the protruding distance of the spiral part 1211 above the conveyor line 200 remains unchanged, the effect of material separation may be affected due to the large distance between the materials 300 and the material distribution device 100.
[0058] Therefore, in order to improve the adaptability of the material distribution device 100, in some embodiments, such as Figure 1 、Figure 2 and Figure 4 as shown Figure 4 As shown, an exploded view of the material distributing device is shown. A rotatable connecting seat 130 is movably arranged on a base 110. A screw rod 121 is rotatably connected to the rotatable connecting seat 130. An adjusting mechanism 140 is movably arranged on the base 110. The adjusting mechanism 140 is connected to the rotatable connecting seat 130. The adjusting mechanism 140 is used to drive the rotatable connecting seat 130 and the screw rod 121 to move relative to the base 110 along an adjusting direction (i.e., the direction indicated by the double arrow N in the figure) when moving, so as to adjust the protruding distance of the spiral part 1211 above the conveying line 200. Among them, the adjusting direction is perpendicular to the extending direction of the screw rod 121 (i.e., the direction indicated by the double arrow M in the figure).
[0059] Specifically, as Figure 4 shown, the rotatable connecting seat 130 may include a first fixing plate 131 and a second fixing plate 132 that are rotatably connected to the screw rod 121. The adjusting mechanism 140 may be directly connected to the first fixing plate 131 and the second fixing plate 132, and the position of the screw rod 121 is adjusted by respectively adjusting the first fixing plate 131 and the second fixing plate 132. Further, in order to facilitate the adjustment of the position of the screw rod 121, the rotatable connecting seat 130 may include a bottom plate 133. Both the first fixing plate 131 and the second fixing plate 132 are fixedly connected to the bottom plate 133. The adjusting mechanism 140 is connected to the bottom plate 133. The adjusting mechanism 140 drives the screw rod 121 to move relative to the base 110 through the bottom plate 133. Such a structure can directly adjust the position of the bottom plate 133 to adjust the position of the screw rod 121, and the operation is simple and convenient.
[0060] As Figure 2 and Figure 4 shown, the adjusting mechanism 140 may be a lead screw adjusting structure, that is, the adjusting mechanism 140 includes a lead screw 141 and a nut fixing seat 142. The lead screw 141 is rotatably connected to the base 110. The rotatable connecting seat 130 is fixedly connected to the nut fixing seat 142. The nut fixing seat 142 is used to drive the rotatable connecting seat 130 and the screw rod 121 to move along the adjusting direction (i.e., the direction indicated by the double arrow N in the figure) when the lead screw 141 rotates. The nut fixing seat 142 is threadedly connected to the lead screw 141. When the lead screw 141 rotates, the nut fixing seat 142 will move along the extending direction of the lead screw 141 (i.e., the direction indicated by the double arrow N in the figure), and drive the rotatable connecting seat 130 thereon to move along the direction indicated by the double arrow N, thereby driving the screw rod 121 to move along the direction indicated by the double arrow N.
[0061] Such a structure can not only easily adjust the positions of the rotating connecting seat 130 and the screw rod 121 by rotating the lead screw 141, but also accurately control the moving distance of the rotating connecting seat 130 and the screw rod 121 through the lead screw 141, avoiding the situation that the protruding distance of the helical part 1211 is too large and affecting the advancement of the material, or avoiding the situation that the protruding distance of the helical part 1211 is too small and resulting in poor blocking effect.
[0062] Of course, the adjusting mechanism 140 can also be a sliding adjustment structure, such as structures like slide rails, guide rails, sliders, linear bearings, etc. By applying a thrust to the rotating connecting seat 130, the rotating connecting seat 130 is made to slide along the guide rail to a preset position, thereby realizing the adjustment of the position of the screw rod 121.
[0063] When separating the materials on the production line, as Figure 1 shown, when the material 300 is small or the width of the conveyor line 200 is large, after the material distributing device 100 is installed on the side of the conveyor line 200, the distance between the material distributing device 100 and the material 300 will be relatively large. At this time, the contact area between the helical part 1211 and the material 300 may be relatively small, or even unable to contact the material 300, which will result in a poor effect of the helical part 1211 restricting the moving speed of the material 300. At this time, the adjusting mechanism 140 can drive the rotating connecting seat 130 and the screw rod 121 to move to the right, increasing the protruding distance of the helical part 1211 above the conveyor line 200, so that the helical part 1211 can stably restrict the moving speed of the material 300. Similarly, if the material 300 is large or the width of the conveyor line 200 is small, the adjusting mechanism 140 can drive the rotating connecting seat 130 and the screw rod 121 to move to the left, reducing the protruding distance of the helical part 1211 above the conveyor line 200, and avoiding the rotating shaft of the screw rod 121 from obstructing the movement of the material 300.
[0064] In the above embodiments, by adjusting the protruding distance of the helical part 1211 above the conveyor line 200, regardless of the size of the material 300 on the conveyor line 200 and the width of the conveyor line 200, it is possible to make the helical part 1211 contact the material 300 and stably restrict the moving speed of the material 300 by adjusting the protruding distance of the helical part 1211 above the conveyor line 200, thereby improving the adaptability of the material distributing device 100.
[0065] Furthermore, when the length of the screw rod 121 is relatively long, the width D1 of the rotating connecting seat 130 will also be relatively large. Therefore, in order to ensure that the rotating connecting seat 130 can be in force balance, in some embodiments, as Figure 3 and Figure 4As shown, the nut fixing seat 142 is located at the middle position of the rotary connecting seat 130. The adjusting mechanism 140 further includes guide rails 143 on both sides of the lead screw 141 and sliders 144 slidably connected to the guide rails 143. The guide rails 143 are arranged on the base 110 and are parallel to the lead screw 141. The sliders 144 are fixedly connected to the rotary connecting seat 130. The sliders 144 are used to slide relative to the guide rails 143 when the rotary connecting seat 130 moves along the adjusting direction (i.e., the direction indicated by the double arrow N in the figure).
[0066] Specifically, as Figure 3 and Figure 4 shown, the nut fixing seat 142 is arranged at the middle position of the rotary connecting seat 130. When the lead screw 141 rotates, the force applied by the nut fixing seat 142 to the rotary connecting seat 130 in the direction indicated by the double arrow N can be concentrated at the middle position of the rotary connecting seat 130, so that the positions on both sides of the rotary connecting seat 130 located on both sides of the lead screw 141 can maintain force balance, avoiding the axial shift of the screw rod 121 due to uneven force. In addition, by arranging the guide rails 143 and the sliders 144 on both sides of the lead screw 141 respectively, not only can the positions on both sides of the rotary connecting seat 130 located on both sides of the lead screw 141 be supported by the guide rails 143 and the sliders 144 to ensure the stability of the rotary connecting seat 130, but also when the rotary connecting seat 130 is subjected to the force in the direction indicated by the double arrow N, the sliders 144 can slide relative to the guide rails 143 to adjust the protruding distance of the spiral parts 1211 at both ends of the screw rod 121 above the conveyor line 200, ensuring that the rotary connecting seat 130 and the screw rod 121 can move smoothly and smoothly.
[0067] In addition, as Figure 3 and Figure 4 shown, the adjusting mechanism 140 further includes a locking member 145. The locking member 145 is movably arranged on the base 110 and is used to lock or unlock the adjusting mechanism 140 when it moves. When the protruding distance of the spiral part 1211 above the conveyor line 200 is adjusted, the adjusting mechanism 140 is locked by the locking member 145 to make the adjusting mechanism 140 immovable, avoiding misoperation and affecting the operation of the feeding device 100, and improving the stability of the feeding device 100. If it is necessary to adjust the protruding distance of the spiral part 1211 above the conveyor line 200, the adjusting mechanism 140 is unlocked by the locking member 145, so as to drive the rotary connecting seat 130 and the screw rod 121 to move relative to the base 110 in the direction indicated by the double arrow N through the adjusting mechanism 140.
[0068] Specifically, assume that the adjusting mechanism 140 is a lead screw adjusting structure, and the locking member 145 can be a hand-tightening screw. When it is necessary to lock the adjusting mechanism 140, the lead screw 141 can be pressed and fixed by tightening the hand-tightening screw, so that the lead screw 141 cannot rotate, thereby locking the adjusting mechanism 140; when it is necessary to unlock the adjusting mechanism 140, the lead screw 141 can be unlocked by loosening the hand-tightening screw, and then the rotating connection seat 130 and the screw rod 121 can be driven to move relative to the base 110 by rotating the lead screw 141.
[0069] According to another aspect of the embodiments of the present application, a material distribution system 1000 is provided, as Figure 1 shown. The material distribution system 1000 includes a conveyor line 200 and the material distribution device 100 described in any of the above embodiments. The conveyor line 200 is used to transport materials 300, and the material distribution device 100 is fixedly arranged on one side of the conveyor line 200. The material distribution device 100 is used to restrict the movement and transportation of the materials 300 on the conveyor line 200 at the position of the material distribution device 100, so that the moving speed of the materials 300 is less than the transportation speed of the conveyor line 200, thereby forming a predetermined interval between the materials 300 on the conveyor line 200 downstream of the material distribution device 100.
[0070] The conveyor line 200 can transport the materials 300 by means of a conveyor belt, roller transmission, chain transmission, etc. The material distribution device 100 can be applied to multiple industries such as food, medicine, and logistics, and is used for automatically separating the materials 300 on the conveyor line 200. The materials 300 can be containers for storing liquids such as plastic bottles and plastic jars, or products such as cans, beverages, and logistics packages. The specific structure of the material distribution device 100 is the same as that described in the embodiments of the material distribution device 100 provided in the above embodiments, and will not be elaborated here.
[0071] The material distribution system 1000 provided by the embodiments of the present application automatically separates the materials 300 on the conveyor line 200 through the material distribution device 100 provided in the above embodiments, so that a predetermined interval is formed between the materials 300 on the conveyor line 200 downstream of the material distribution device 100, thereby reducing the difficulty of subsequent processes and improving the overall production efficiency of the production line.
[0072] Furthermore, when the materials 300 on the conveyor line 200 downstream of the material distribution device 100 are congested, in order to prevent the materials 300 from continuously flowing into the downstream and resulting in the failure of separating the materials 300, in some embodiments, as Figure 1 、 Figure 5 and Figure 6 shown, Figure 5 shows Figure 1 an enlarged schematic view of B in Figure 6The partial structure of the material distribution system is shown. At least three sensing devices 400 are arranged at intervals at a position downstream of the material distribution device on the conveyor line 200, and the distance between two adjacent sensing devices 400 is equal to the width of the material 300. The at least three sensing devices 400 are used to detect whether there is a material 300 at the corresponding position on the conveyor line 200. The material distribution system 1000 further includes a control device (not shown in the figure). The control device is respectively signal-connected to the sensing device 400 and the driving member 122 of the material distribution device 100. The control device is used to control the driving member 122 to close when at least three sensing devices 400 all detect the material 300, so that the screw rod 121 stops and abuts against the material 300 through the spiral portion 1211 thereon to prevent the material 300 from moving along the conveyor line 200.
[0073] The sensing device 400 is used to detect whether there is a material 300 at the corresponding position on the conveyor line 200. The sensing device 400 can be a photoelectric sensor, an infrared sensor, a laser sensor, etc. The distance D2 between two adjacent sensing devices 400 is equal to the width L1 of the material 300 to ensure that the materials 300 detected by each sensing device 400 are not the same one. When the materials 300 move at a predetermined interval (as Figure 5 shown), the position detected by at least one sensing device 400 is the interval between the materials 300, and when the materials 300 are congested (as Figure 6 shown), when the interval between the materials 300 is too small, the positions detected by the three sensing devices 400 all have the materials 300.
[0074] Therefore, when all the sensing devices 400 arranged on the conveyor line 200 detect the material 300, it can be determined that the materials 300 downstream of the material distribution device 100 on the conveyor line 200 are congested, and the driving member 122 needs to be closed in time, so that the screw rod 121 stops rotating, thereby preventing the materials 300 from continuing to enter the downstream, preventing the materials 300 from continuously flowing into the downstream, resulting in the failure of separating the materials 300 and affecting the operation of subsequent processes.
[0075] Based on the material distribution system 1000 provided in the above embodiment, according to another aspect of the embodiment of the present application, a material distribution method is further provided. This method is applied to the material distribution system 1000 described in any of the above embodiments. For details, please refer to Figure 1 and further in combination with Figure 7 and Figure 8 Figure 7 shows another partial structure of the material distribution system, Figure 8 The flow of the material distribution method is shown in. As shown in the figure, this method includes the following steps:
[0076] Step S510: Obtain the width L1 of the material 300 and the required spacing L2 between two adjacent materials 300.
[0077] Step S520: Determine the sum of the width L1 and the spacing L2 as the first distance that the material 300 moves when being conveyed by the conveyor line 200 during one rotation of the screw rod 121.
[0078] Step S530: Obtain the conveying speed of the conveyor line 200, and determine the ratio between the first distance and the conveying speed of the conveyor line 200 as the time required for one rotation of the screw rod 121.
[0079] Step S540: Obtain the pitch L3 of the spiral part 1211 on the screw rod 121, and determine the ratio between the pitch L3 and the time as the conveying speed on the surface of the screw rod 121.
[0080] Step S550: Obtain the parameters of the screw rod 121, and determine the rotational speed of the screw rod 121 according to the conveying speed on the surface of the screw rod 121 and the parameters.
[0081] Step S560: Control the driving member 122 to work and drive the screw rod 121 to rotate at the rotational speed.
[0082] Specifically, the required spacing L2 between two adjacent materials 300 is the interval that the material 300 needs to maintain when moving on the conveyor line 200, and it is also a key parameter in the production line, which will directly affect the production efficiency, product quality, etc. Therefore, the required spacing L2 between two adjacent materials 300 is usually set by the user according to factors such as the material characteristics, transmission mode, technological process, and equipment capacity of different production lines.
[0083] As Figure 3 shown, the interval (i.e., the required spacing L2) between two adjacent materials 300 on the conveyor line 200 is formed by the speed difference between the materials 300. Specifically, the speed difference between the conveying speed of the conveyor line 200 and the moving speed of the material 300 when being blocked by the spiral part 1211 will cause a difference in the moving distances of the material Q2 and the material Q1 on the conveyor line 200, and this difference is the interval between two adjacent materials 300. When the spacing L2 is known, the rotational speed of the screw rod 121 can be inversely deduced through the conveying speed of the conveyor line 200, and the driving member 122 is controlled to drive the screw rod 121 to rotate at the deduced rotational speed, so as to form a predetermined interval between the materials 300 located downstream of the material distributing device 100 on the conveyor line 200.
[0084] Specifically, as Figure 7As shown in the figure, assume that the material 300 moves in the direction indicated by the arrow X. The material Q1 is the material not blocked by the spiral part 1211. At this time, the moving speed of the material Q1 is the conveying speed V1 of the conveyor line 200, while the material Q2 is still in the screw rod 121, and the moving speed of the material Q2 is restricted by the spiral part 1211, that is, the moving speed of the material Q2 is the conveying speed V2 of the screw rod 121. In addition, after the screw rod 121 rotates one week, the material Q2 can reach the end of the screw rod 121 (i.e., the position where the material Q1 is located at this time). The moving distance of the material Q2 is the pitch L3 of the spiral part 1211. And within the time when the screw rod 121 rotates one week, the material Q1 will reach the position where the material Q3 is located under the conveying of the conveyor line 200. The moving distance of the material Q1 is the sum of the width L1 and the spacing L2 of the material 300. Therefore, the following relational formula can be obtained:
[0085]
[0086] Converting the above relational formula, the calculation formula for the conveying speed V2 of the screw rod 121 can be obtained as:
[0087]
[0088] Therefore, after the required spacing L2 between the materials 300 is known, the conveying speed of the screw rod 121 can be calculated through the above formula (1), and then the rotation speed of the screw rod 121 can be determined in combination with the parameters of the screw rod 121 (for example, the conversion parameters between the diameter, angle and radian of the screw rod 121). Finally, the driving part 122 is started, and the driving part 122 drives the screw rod 121 to rotate at this rotation speed.
[0089] Specifically, the conversion between the conveying speed V2 on the surface of the screw rod 121 and the rotation speed V3 of the screw rod 121 can be carried out through the following formula:
[0090] V2 = D×V3×0.0524
[0091] Among them, D and 0.0524 are the parameters of the screw rod 121. D is the diameter of the screw rod 121, and 0.0524 is the conversion constant between the angle and the radian. Converting the above formula, the rotation speed V3 of the screw rod 121 can be obtained:
[0092]
[0093] In the embodiments of the present application, the width of the material 300, the required spacing between two adjacent materials 300, and the pitch of the spiral part 1211 are obtained, and the conveying speed on the surface of the screw rod is calculated by formula (1) in the embodiment of the above-mentioned material distributing device. Then, in combination with the parameters of the screw rod 121, the rotation speed of the screw rod 121 is determined. Finally, the driving member 122 is controlled to drive the screw rod 121 to rotate at the corresponding rotation speed, so as to realize the automatic separation of the materials 300 and improve the degree of automation of the production line.
[0094] Further, in order to prevent the materials 300 from continuously flowing into the downstream and resulting in the failure of separating the materials 300, at least three sensing devices 400 are arranged at intervals at the position downstream of the material distributing device 100 on the conveyor line 200, and the distance between two adjacent sensing devices 400 is equal to the width of the material 300. The method further includes the following steps:
[0095] Step S610: Detect whether there is a material 300 at the corresponding position on the conveyor line 200 through at least three sensing devices 400.
[0096] Step S620: If at least three sensing devices 400 all detect the material 300, control the driving member 122 to close, so that the screw rod 121 stops and abuts against the material 300 through the spiral part 1211 thereon to prevent the material 300 from moving along the conveyor line 200.
[0097] The process of detecting whether the materials 300 downstream of the conveyor line 200 are blocked by at least three sensing devices 400 and preventing the materials 300 from continuously flowing into the downstream when the materials 300 are blocked is the same as the description of the usage process of the sensing device 400 in the embodiment of the material distributing system provided above, and will not be elaborated here.
[0098] The material distributing method provided by the embodiments of the present application detects the materials 300 located downstream of the material distributing device 100 on the conveyor line 200 through at least three sensing devices 400, so as to prevent the materials 300 upstream of the conveyor line 200 from continuing to flow along the conveyor line 200 when the materials 300 are blocked, prevent the materials 300 from continuously flowing into the downstream, and cause the failure of separating the materials 300, affecting the operation of subsequent processes.
