Description

Technical Field

[0001] This utility model relates to the field of bottle conveying technology, specifically to a conveying mechanism and a bottle processing system. Background Technology

[0002] The primary function of a conveyor line is limited to transporting containers such as bottles. However, in the actual bottle production process, the bottles require multiple processing steps, such as washing, filling, capping, screwing on caps, and labeling. The processing equipment for these steps needs to coordinate with the conveyor line and the bottles on it to complete the entire bottle production process. Depending on the processing method, the equipment for these steps is mainly divided into two types: linear processing and rotary processing.

[0003] When all processing equipment uses linear processing, the bottles can still be transported and processed on the original conveyor line for processes such as filling, capping, and screw capping. However, when some processing equipment uses rotary processing, the bottle conveying method needs to be changed from linear to rotary. In this case, bottle separating components are required to assist in separating the bottles. To ensure the accuracy of bottle feeding and avoid gaps in the bottle separating components, which could lead to missed processing, the bottles on the conveyor line in front of the bottle separating components are usually stacked together to ensure the supply of bottles.

[0004] Furthermore, due to differences in the technological characteristics and equipment performance of different processes, the processing speeds of different processes vary. To avoid the need for a large number of bottles to be piled up before processes with low processing efficiency, which could lead to bottle tipping or collision damage, the length of the conveyor line before the low-efficiency process is usually extended, or the speed of a single conveyor line is varied to coordinate the differences in production efficiency between the preceding and following processes. However, extending the conveyor line increases the footprint of the entire production line; when a single conveyor line switches between high and low speeds midway, the bottles (especially tall and narrow bottles) are prone to displacement or tipping due to inertia. In particular, the bottles at the front and rear ends of a group of bottles are more likely to tip over due to changes in inertial forces, causing instability in the center of gravity and resulting in bottle tipping or jamming, which affects equipment operation.

[0005] Therefore, there is an urgent need to design a conveying mechanism that does not increase the footprint of the conveyor line and can effectively prevent the bottles from tipping over or colliding during variable speed conveying, so as to improve production efficiency and reduce failure rate. Utility Model Content

[0006] The purpose of this utility model is to overcome the defects of the prior art and provide a conveying mechanism and bottle processing system, which can solve the problems of large space occupation of the conveying line, high bottle tilting rate and easy collision damage during variable speed conveying.

[0007] To achieve the above objectives, this utility model provides the following technical solution: Firstly, this utility model proposes a conveying mechanism, comprising a first conveyor line, the output section of which forms an obtuse angle with its main body section; a second conveyor line, the main body of which is colinearly arranged with the main body section of the first conveyor line, and its input section is tangentially arranged with the output section of the first conveyor line to form a transition zone; a guardrail installed on one side of the transition zone; and a bottle-separating assembly installed on the other side of the transition zone. The bottle-separating assembly and the guardrail cooperate to clamp and separate the bottles, allowing the bottles to undergo speed change and separation in the transition zone, while maintaining a straight path from the first conveyor line into the second conveyor line.

[0008] In one embodiment, the bottle separating assembly includes a screw rotatably mounted on the other side of the transition zone; the screw has a spiral groove, which, together with the guardrail, restricts the separated bottles, and the spiral groove restricts the moving speed of the bottles to be less than or equal to the conveying speed of the second conveyor line.

[0009] In one embodiment, the spiral groove covers the main body section of the first conveyor line, the transition zone, and the main body section of the second conveyor line.

[0010] In one embodiment, the conveying mechanism further includes a work station plate, on which n work station openings are equally spaced along the circumference, and the ratio of the rotational speed of the work station plate to the rotational speed of the screw is 1:n.

[0011] In one embodiment, the pitch of the spiral grooves is equal, and the pitch is equal to the arc length of the interval between two adjacent work positions.

[0012] In one embodiment, the pitch of the spiral groove gradually increases from the first conveyor line to the second conveyor line to a maximum pitch, the maximum pitch being equal to the arc length between two adjacent workstations.

[0013] In one embodiment, the pitch of the spiral groove gradually increases from the first conveyor line to the second conveyor line to the maximum pitch and then remains unchanged at the maximum pitch. The maximum pitch is equal to the arc length between two adjacent workstations.

[0014] In one embodiment, the thread cross-sectional shape of the spiral groove matches the shape of the bottle body.

[0015] In one embodiment, when the productivity of the previous process is greater than or less than the productivity of the next process, the conveying speed of the first conveyor line is less than or greater than the conveying speed of the second conveyor line.

[0016] As a second aspect, the present invention also provides a bottle processing system, including at least two processing devices; and a conveying mechanism as described in the first aspect, disposed between two adjacent processing devices.

[0017] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The first conveyor output section and the second conveyor input section of this utility model adopt tangential technology, which can realize that the main sections of the two conveyor lines are collinear, and the docking part of the two conveyor lines forms a transition zone without bottle turning or gaps. The setting of the transition zone increases the contact area of ​​the two conveyor lines, which can weaken the impact of sudden speed change and reduce the risk of bottle tipping. Compared with two conveyor lines set side by side, it can avoid setting up complex mechanical guidance devices, simplify the overall structure of the conveyor mechanism, and avoid unnecessary collisions during line turning. Compared with two conveyor lines set up front and back, it can avoid the generation of transition gaps, thereby avoiding the problem that the gap area cannot provide support for the bottom of the bottle and is more likely to cause the bottle to tilt. Compared with the design of a single conveyor line changing speed in the middle, it can reduce displacement or tipping due to inertia.

[0019] 2. The bottle-separating assembly of this utility model adopts a screw with a spiral groove, and the spiral groove limits the moving speed of the bottle to less than the conveying speed of the second conveyor line. This allows the spiral groove on the screw to only play the role of limiting support, separating bottles, and blocking the movement of the bottle, while avoiding the generation of force that pushes the bottle, thus preventing the bottle from shaking, getting stuck, or tipping over.

[0020] 3. The spiral groove of this utility model, that is, the functional area of ​​the screw, simultaneously covers the main body section and the transition area of ​​two conveyor lines, which can ensure that the bottle is separated and limited and supported. Compared with being limited and supported only after speed change, it can further improve the anti-tipping ability.

[0021] 4. The design of the ratio between the station plate speed and the screw speed in this utility model can ensure the accuracy of bottle inlet at the station.

[0022] 5. The spiral grooves of this utility model have equal pitches, which can enable the bottles to automatically spread out at equal intervals after entering the spiral grooves;

[0023] 6. The pitch of the spiral groove of this utility model increases from small to large. In the time it takes for the screw to rotate once, the bottle in the small pitch area is decelerated quickly, and the bottle in the large pitch area is further accelerated. This makes the bottle first eliminate the inertial force and center of gravity shift after speed change under the action of the screw when it enters the second conveyor line from the first conveyor line, and then accelerates into the station inlet in sequence, reducing the possibility of the bottle tipping over.

[0024] 7. The pitch of the spiral groove of this utility model first increases from small to large and then remains constant. The bottle in the small pitch area is rapidly decelerated, first eliminating the inertial force and center of gravity shift after speed change, reducing the possibility of the bottle tipping over, and then automatically equidistantly arranging them and accelerating into the work station inlet in sequence.

[0025] 8. The spiral groove shape of this utility model matches the bottle body, which can further improve the limiting and supporting ability of the spiral groove on the bottle body;

[0026] 9. The conveying speed design of the first and second conveying lines of this utility model can ensure that when the production rate of the next process is high, bottles can be stacked as soon as possible before being conveyed into the next process to ensure the supply of bottles; when the production rate of the previous process is high, it is not easy for a large number of bottles to be crowded in front of the transition zone, reducing the risk of collision, squeezing or tipping between bottles, and avoiding the problem of increasing the footprint of the conveying line by extending the first conveying line.

[0027] 10. The conveying mechanism provided by this utility model has a simple and ingenious structure, and is suitable for various multi-process automated processing production lines, especially for bottle processing systems. Attached Figure Description

[0032] It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are only used to complement the content disclosed in the specification for those skilled in the art to understand and read, and are not intended to limit the conditions under which this utility model can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0033] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains. The terms “a,” “an,” or “the,” as used herein, do not indicate a limitation of quantity, but are merely used to indicate the presence of at least one. Terms such as “comprising” or “including” mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. The numbering of components in this specification, such as “first,” “second,” etc., is used only to distinguish the described objects and has no sequential or technical meaning. The term “connection,” unless otherwise specified, includes both direct and indirect connections. As used herein, “front and back” refers to the conveying direction of the bottle body 200, and “left and right” refers to directions perpendicular to the conveying direction of the bottle body 200 on the same horizontal plane.

[0034] To avoid confusion with this utility model, some technical features known in the art have not been described.

[0035] like Figure 1 and Figure 2As shown, this embodiment provides a conveying mechanism disposed between two adjacent processing devices for conveying bottles 200. The bottles 200 can be empty or filled, and the types and sizes of the bottles 200 are diverse. The conveying mechanism includes a first conveyor line 110, a second conveyor line 120, a guardrail 130, a bottle separating assembly 140, and a workstation tray 150. An obtuse angle is formed between the output section 112 and the main body section 111 of the first conveyor line 110; an equal obtuse angle is also formed between the input section 122 and the main body section 121 of the second conveyor line 120; the input section 122 of the second conveyor line 120 and the output section 112 of the first conveyor line 110 are tangent to form a transition zone 101, and the main body section 121 of the second conveyor line 120 and the main body section 111 of the first conveyor line 110 are collinear, so that the bottle 200 does not need to be reversed after passing through the transition zone 101, thus avoiding the problem of instability of the center of gravity of the bottle 200 during the conveying process due to the need for reversing the conveying. The guardrail 130 is installed on one side of the transition zone 101; the bottle-separating assembly 140 is installed on the other side of the transition zone 101; the bottle-separating assembly 140 cooperates with the guardrail 130 to clamp and separate the bottles 200, so that the bottles 200 complete speed change and separation in the transition zone 101, and maintain a straight path from the first conveyor line 110 to the second conveyor line 120. The bottles 200 placed or processed in the previous process are stacked and conveyed in the first conveyor line 110. When the bottles 200 reach the transition zone 101, they are speed changed and separated by the bottle-separating assembly 140, and under the limiting support of the bottle-separating assembly 140 and the guardrail 130, they enter the station port 151 of the station tray 150 in sequence. The bottles 200 entering the station port 151 are limited by the support plate and the limiting ring 160, and are conveyed to the processing position for subsequent processing as the station tray 150 rotates.

[0036] In this embodiment, the two conveyor lines adopt a tangential technique, which can form a gapless transition zone 101 at the docking point of the two conveyor lines. The setting of the transition zone 101 increases the contact area of ​​the speed change docking, which can weaken the impact of sudden speed change and reduce the risk of bottle tipping. After the bottle 200 enters the transition zone 101, it is clamped and limited by the bottle separating component 140 and the guardrail 130, which can prevent the bottle tipping phenomenon from occurring.

[0037] Furthermore, guardrails 130 are respectively provided on both sides of the main body section 111 of the first conveyor line 110. The guardrails 130 on both sides work together to clamp the bottle 200, ensuring that the bottle 200 will not tilt to the left or right during the conveying process. The bottles 200 on the first conveyor line 110 are placed tightly together before entering the transition zone 101. On the one hand, this creates a limit and support between adjacent bottles 200, preventing the bottles 200 from tilting forward or backward. On the other hand, it can create a bottle stacking phenomenon before entering the transition zone 101, ensuring the supply of bottles 200 waiting to enter the bottle separating component 140, and ensuring that the bottle separating component 140 does not have empty conveying positions.

[0038] Furthermore, the bottle-separating assembly 140 includes a screw 141, which is rotatably mounted on the other side of the transition zone 101. A helical groove 142 is formed on the screw 141, and the helical groove 142, together with the guardrail 130, restricts the separated bottle bodies 200. The threaded cross-sectional shape of the helical groove 142 can be obtained by axially sectioning the screw 141. The threaded cross-sectional shape of the helical groove 142 matches the shape of the bottle body 200 in contact with the threaded portion. For example, if the outer contour of the main body of the bottle body 200 is cylindrical, then the threaded cross-sectional shape of the helical groove 142 is an arc; if the outer contour of the main body of the bottle body 200 is cuboid, then the helical groove 142 is a square groove. In order to ensure that the screw 141 only serves to limit support, separate bottles, and block the movement of the bottle body 200, and avoids generating a force that pushes the bottle to move, and avoids the bottle body 200 from shaking and tipping over, the spiral groove 142 needs to limit the moving speed of the bottle body 200 to be less than or equal to the conveying speed of the second conveyor line 120.

[0039] Furthermore, the functional area of ​​the screw 141 can be designed to simultaneously cover the main body section 111 of the first conveyor line 110 and the main body section 121 of the second conveyor line 120. That is, the spiral groove 142 covers the main body section 111 of the first conveyor line 110, the transition area 101, and the main body section 121 of the second conveyor line 120. This design allows the bottle 200 to be limited and supported before speed change, which, compared to being limited and supported only after speed change, further improves the anti-tipping ability.

[0040] Typically, the workstation openings 151 on the workstation plate 150 are arranged at equal intervals along the circumference. Therefore, to ensure that the screw 141 can accurately feed the bottle 200 into the workstation openings 151 sequentially, the speed of the workstation plate 150 and the rotational speed of the screw 141 need to be in a specific ratio. Specifically, when the number of workstation openings 151 is n (n is a positive integer, such as 6 or 8), then in the same time interval, the screw 141 rotates n times for the workstation plate 150 to rotate one time, that is, the ratio of the rotational speed of the workstation plate 150 to the rotational speed of the screw 141 is 1:n. Simultaneously, the pitch of the thread groove closest to the workstation plate 150 should be equal to the arc length of the interval between two adjacent workstation openings 151.

[0041] In some embodiments, the pitch of the spiral grooves 142 can be equal, and the equal pitch can enable the bottle body 200 to automatically spread out at equal intervals after entering the spiral grooves 142.

[0042] In other embodiments, to ensure that when the bottle 200 enters the second conveyor line 120 from the first conveyor line 110, the screw 141 first eliminates the inertial force and center of gravity shift after speed change, further reducing the possibility of the bottle 200 tipping over. Figure 1 As shown, the pitch of the spiral groove 142 can gradually increase from the first conveyor line 110 to the second conveyor line 120 to the maximum pitch; or the pitch of the spiral groove 142 can first gradually increase from the first conveyor line 110 to the second conveyor line 120 to the maximum pitch and then keep the maximum pitch unchanged. The maximum pitch is equal to the arc length between two adjacent workstation openings 151.

[0043] Furthermore, since the bottle 200 needs to be released from the clamp of the guardrail 130 when the screw 141 feeds the bottle 200 into the work station 151, the conveying speed of the second conveyor line 120 should be greater than the speed at which the work station 150 moves with the bottle to prevent the bottle 200 from tipping over due to shaking during this process. This is because, according to the thread direction and rotation direction of the screw 141, the screw 141 rotates towards the conveying surface of the conveyor line, and the force is inclined downward. If the conveying speed of the second conveyor line 120 is less than or equal to the speed at which the work station 150 moves with the bottle, the screw 141 will act as a pusher, causing the bottle 200 to tilt downward and vibrate, resulting in the bottle 200 tipping over due to shaking.

[0044] Specifically, the first conveyor line 110, the second conveyor line 120, the bottle separating assembly 140, and the workstation tray 150 are driven by a first drive device, a second drive device, a third drive device, and a fourth drive device, respectively. The first, second, third, and fourth drive devices can be motors, which not only provide stable driving force but also allow for adjustment of the conveyor speed according to actual conditions. However, the conveying speed of the first conveyor line 110 must always be greater than or less than the conveying speed of the second conveyor line 120.

[0045] When the upstream process of the first conveyor line 110 is bottle placement, the conveying speed of the first conveyor line 110 can be greater than or less than the conveying speed of the second conveyor line 120. This can be achieved simply by adjusting the bottle placement speed of the bottle placement device to ensure bottle stacking before the transition zone 101. When the upstream process of the first conveyor line 110 is filling, and the equipment for capping or screwing on the filled bottles 200 is not an integrated machine, the filling speed is slow while the capping or screwing speed is fast. Therefore, bottle stacking needs to be formed before the bottles are conveyed into the capping or screwing equipment. In this case, the conveying speed of the first conveyor line 110 needs to be coordinated with the filling process, and the conveying speed of the second conveyor line 120 needs to be coordinated with the capping or screwing process. Furthermore, the conveying speed of the first conveyor line 110 needs to be greater than the conveying speed of the second conveyor line 120. This ensures that the bottles 200 quickly form a bottle stack before the transition zone 101 and reach the transition zone 101 faster, allowing for rapid processing of the next process and ensuring that the supply of bottles 200 meets the production efficiency requirements of the next process. When the upstream process of the first conveyor line 110 is bottle washing and the downstream process is filling, bottle washing is fast and filling is slow, meaning that the productivity of bottle washing is high. In this case, the conveying speed of the first conveyor line 110 needs to be coordinated with the bottle washing process, and the conveying speed of the second conveyor line 120 needs to be coordinated with the filling process. Furthermore, the conveying speed of the first conveyor line 110 should be less than the conveying speed of the second conveyor line 120. This will prevent a large number of bottles 200 from crowding in front of the transition zone 101, reducing the risk of collisions, squeezing, or tipping between bottles 200. At the same time, it can avoid the need to extend the conveyor line to avoid crowding and avoid increasing the floor space occupied by the conveyor line.

[0046] This embodiment also provides a bottle processing system, including at least two processing devices and a conveying mechanism disposed between two adjacent processing devices.

[0047] In summary, the conveying mechanism provided by this utility model has a simple and ingenious structure, and is suitable for various multi-process automated processing production lines, especially for bottle processing systems. On the one hand, the two conveyor lines adopt a tangential technology, which can expand the contact area of ​​the variable speed docking, weaken the impact of sudden speed changes, and reduce the risk of bottle tipping and jamming. On the other hand, by adjusting the conveying speed, the bottles 200 that are equally spaced can better cooperate with the processing position of the workstation 150, making product processing smoother, reducing the occurrence of failures, reducing labor costs for enterprises, and increasing production capacity.

[0048] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
