Description

Technical Field

[0001] The present application relates to the technical field of conveying equipment, and in particular to a clamping chain conveying equipment. Background Art

[0002] A chain conveyor is a conveying device that uses a chain as a bearing surface and a motor reducer as a power transmission. A chain conveyor is composed of a power device (usually a motor), a drive shaft, a roller, a tensioning device, a sprocket, a chain, a bearing, a lubricant, a chain, etc. The two main parts that drive the conveying of materials are: the chain, which uses its reciprocating motion to provide traction power; and the metal plate, which serves as a carrier during the conveying process. A clamping chain is a common type of chain, which usually has a clamping element at the chain, and uses the friction between the clamping element and the product to keep the product in a relatively stable position during conveying, so that the product can adapt to the needs of turning and up and down conveying during conveying.

[0003] However, after the product has been conveyed horizontally normally, it needs to be fed into the clamping chain plate during the conveying process. The two are usually not directly connected and used simply because the clamping chain plate usually needs to ensure that the product is transported to a specific position at a specific speed during actual production. In order to achieve the corresponding accuracy of feeding, it is necessary to use precise transfer equipment or manually control the feeding. Such transfer equipment usually needs to consider the feeding frequency of the product during transfer and the accurate grasping of the product at the same time. It has high requirements for the equipment, so the cost is high and it is difficult to repair in case of failure. Manual control is prone to fatigue during the continuous production process of the production line. To this end, we propose a clamping chain conveyor device. Summary of the invention

[0004] The purpose of the present application is to provide a clamping chain conveying device.

[0005] To achieve the above objectives, the technical solution adopted in the present application is: a clamping chain conveyor device, comprising a feeding mechanism, a transfer mechanism and a material-discharging mechanism arranged at the entrance of the transfer mechanism. When the feeding mechanism is in operation, the product is driven to move toward the entrance direction of the transfer mechanism by friction. The material-discharging mechanism comprises a material-discharging component for driving the product to move and an elastic limiting component for limiting the movement of the product. In a natural state, the elastic limiting component abuts against the nearest product to position the product in a fixed position of the feeding mechanism. When the material-discharging component is in operation, it acts on the product, the product moves and causes the elastic limiting component to elastically deform. After the product passes through the elastic limiting component, the next product is conveyed forward by the feeding mechanism and abuts against the reset elastic limiting component, thereby reciprocating to form periodic feeding.

[0006] As a preferred embodiment, a material shifting space is formed at the junction of two adjacent products; the material shifting mechanism includes a rotatably arranged shifting plate, which rotates in a specified direction around its axis, and acts on the product as it continues to rotate after entering the material shifting space, so that the product moves toward the entrance direction of the feeding mechanism.

[0007] As a preference, the material shifting mechanism is arranged on both sides of the feeding mechanism and is symmetrical to each other. When rotating, the two material shifting mechanisms on both sides rotate at the same speed and in opposite directions, so that the two shifting plates on both sides remain symmetrical when rotating.

[0008] Preferably, the transfer mechanism comprises a first clamping portion and a second clamping portion, the first clamping portion and the second clamping portion both comprise a chain plate and a clamping element, the chain plate comprises a chain, a supporting roller, a tensioning roller and a transmission roller, a driving portion is arranged on the outer side of the transmission roller, the supporting roller, the tensioning roller and the transmission roller respectively form a specific configuration of the chain; the clamping element is fixed on the chain to form a clamping chain plate.

[0009] As a preferred embodiment, the transmission roller and the driving part are connected by means of a first transmission sprocket and a synchronous belt, a first driven gear is provided at the bottom of the shift plate, a combined transmission member is provided on the outer side of the first driven gear, the combined transmission member includes a second driven gear at the top and a second transmission sprocket at the bottom, the second driven gear and the first driven gear are meshed, and the second transmission sprocket is also provided on the corresponding synchronous belt, so that the second transmission sprocket and the first transmission sprocket can move synchronously with each other at a corresponding transmission ratio, thereby making the first driven gear synchronized with the transfer mechanism and moving at a corresponding transmission ratio.

[0010] As a preferred embodiment, the second driven gear includes a plurality of transmission teeth and a transmission interval which is one less than the number of the transmission teeth. The transmission teeth of the second driven gear mesh with the first driven gear, and each group of the transmission teeth and the first driven gear act to rotate the paddle 360°, and the transmission interval does not act with the first driven gear, so that the paddle pauses after each rotation and then continues to rotate, so that the feeding interval increases.

[0011] As a preference, two driving parts are provided corresponding to the first clamping part and the second clamping part, and a gearbox is provided corresponding to the driving part, and the two driving parts are electronically controlled to rotate synchronously.

[0012] As a preference, the driving part is provided with one corresponding to the first clamping part and the second clamping part, and the driving part is provided with a gear set and a gearbox correspondingly, and the gear set enables the driving part to drive the first clamping part and the second clamping part to operate simultaneously.

[0013] Preferably, the elastic limiting assembly includes two mounting parts fixedly arranged on both sides of the feeding mechanism, the mounting parts are provided with limiting plates which can be slidably arranged in a direction perpendicular to the feeding direction, a spring is arranged between the limiting plate and the inside of the mounting part, and a guide part is arranged at the end of the limiting plate close to the product side; in an initial state, the spring makes the distance between the two limiting plates on both sides smaller than the outer diameter of the product so that the product and the limiting plates abut against each other; when the shift plate acts on the product, the product acts on the guide part to move the limiting plate outward and compress the spring, thereby allowing the product to pass through, and the spring is reset at the moment the product passes through so that the next product is blocked.

[0014] Preferably, the clamping element includes a Y-shaped clamping portion and a mounting portion connected to the chain, the clamping portion is laterally arranged on a side of the mounting portion, the head of the clamping portion is vertical and extends out of the chain to connect with the product, and the tail of the clamping portion is fixedly connected to the mounting portion.

[0015] Compared with the prior art, the beneficial effects of this application are: The material-dispensing assembly only needs to be able to move in a cycle and push the material in the feeding direction. The frequency is achieved through the periodic movement of the material-dispensing assembly itself on the one hand, and through the elastic limiting assembly on the other hand. The elastic limiting assembly will only elastically deform and allow the product to pass when the material-dispensing assembly applies pressure to the product. When the material-dispensing assembly pushes out all the products this time, the elastic limiting assembly will automatically reset immediately so that the subsequent products continue to be blocked and cannot move. Through the above setting of the material-dispensing assembly, stable feeding of the product from the feeding mechanism to the transfer mechanism can be easily achieved.

DETAILED DESCRIPTION

[0031] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application.

[0033] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0034] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0035] Embodiment 1: Reference Figures 1 to 13 As shown, this embodiment provides a clamping chain plate conveying device, which mainly includes a feeding mechanism 1 and a transfer mechanism. The feeding mechanism 1 is as shown in FIG. Figure 1 As shown, it is preferred to use a chain conveyor to convey the product 4, but other conveying equipment may also be selected. Figure 2 , Figure 3 As shown, the product 4 conveyed by the conveying device can be bottles of different shapes, or any other suitable product 4 objects. The conveying device is mainly used for bottle conveying, so the subsequent product 4 is as shown in FIG. Figure 3 The bottle body shown is used as an example for explanation, that is, the concepts of "product 4" and "bottle body" can be understood interchangeably.

[0036] In order to ensure the conveying of the bottle, in addition to using the loading mechanism 1 for translational transportation, various production lines also require that the bottle can be conveyed by turning or clamping. Figure 1After the chain plate is conveyed, the conveying process of the clamping chain plate needs to control the feeding of the bottle body to ensure that the clamping chain plate transports the product 4 to a specific position at a specific speed. In order to achieve the corresponding precision of feeding, it is necessary to use precise transfer equipment or manually control the feeding. Such transfer equipment usually needs to consider the feeding frequency of the product 4 during transfer and the accurate grasping of the product 4 at the same time. The equipment has high requirements, so the cost is high, and it is difficult to repair when it fails; and manual control is prone to fatigue during the continuous production process of the production line.

[0037] like Figures 1 to 8 As shown, unlike the prior art, the conveying device of this embodiment is also provided with a material-dispensing mechanism at the entrance of the transfer mechanism. When the feeding mechanism 1 is in operation, the product 4 is driven to move toward the entrance direction of the transfer mechanism by friction. The material-dispensing mechanism includes a material-dispensing component for dispensing the product 4 and an elastic limiting component 9 for limiting the movement of the product 4. The elastic limiting component 9 abuts against the nearest product 4 in a natural state so that the product 4 is positioned at a fixed position of the feeding mechanism 1. When the material-dispensing component is in operation, it acts on the product 4, and the product 4 moves and elastically deforms the elastic limiting component 9. After the product 4 passes through the elastic limiting component 9, the next product 4 is conveyed forward by the feeding mechanism 1 and abuts against the reset elastic limiting component 9, so as to form periodic feeding by reciprocating. Obviously, when the product 4 is sent to the feeding mechanism 1, it is only necessary to place the product 4 near the middle of the feeding mechanism 1, so no complicated operation is required whether it is manually controlled or transferred using equipment. The material-digging component itself only needs to be able to move in a periodic manner and push the material in the feeding direction. Its frequency is achieved on the one hand by the periodic movement of the material-digging component itself, and on the other hand by the elastic limiting component 9. The elastic limiting component 9 will only be elastically deformed and allow the product 4 to pass when the material-digging component applies pressure to the product 4. When the material-digging component pushes out all the products 4 this time, the elastic limiting component 9 will automatically reset immediately so that the subsequent products 4 continue to be blocked and cannot move. Furthermore, according to the above principle, the number of products 4 pushed by the material-digging component each time can also be one or more, and multiple products 4 are arranged in sequence, and the material-digging component acts on the last product 4 to push it forward. Of course, based on the above principle, the periodic feeding of the above-mentioned material-digging component can also be changed to feeding with a specific frequency under certain conditions.

[0038] Without setting additional limiting parts, if the product 4 is just a hollow plastic bottle, if the material transfer assembly pushes multiple plastic bottles at one time, the product 4 is likely to fall over. To avoid this, two limiting plates can be adaptively set on the feeding device to ensure that the bottles are generally stable when arranged. If the bottles are filled with liquid or glass bottles, which are relatively stable in themselves, there is no need to set the limiting plate 13 to ensure that the bottles are relatively stable when pushed and do not often fall over.

[0039] Embodiment 2: Reference Figure 3 , Figure 4 As shown, the material-dispensing mechanism includes a rotatably arranged dial plate 7, and the dial plate 7 rotates in a specified direction around its axis, as shown in FIG. Figure 3 As shown, the dial plate 7 includes a rotating portion 8, and the dial plate 7 can be rotated by the setting of the rotating portion 8. The installation method of the dial plate 7 in the figure is easy to associate, and the present application only requires that the dial plate 7 can be stably rotated, so its specific installation structure is not limited; in order to ensure that the rotating dial plate 7 can act on the appropriate position of the product 4, a material-shifting space needs to be formed at the junction of two adjacent products 4, such as Figure 3 As shown, the material shifting space is between the two products 4 on the right; after rotating into the material shifting space, the product 4 is acted on when the product 4 continues to rotate, so that the product 4 moves toward the entrance direction of the feeding mechanism 1. In this embodiment, the material shifting component is preferably set as a rotating shifting plate 7. Figure 4 , the product 4 is placed above the feeding mechanism 1. When the feeding mechanism 1 is set as a chain conveyor, the friction force causes the product 4 to move to the left. Figure 4 For the sake of illustration, the right chain plate is shorter and can carry fewer products 4. Other conveying mechanisms can be added to transport the products 4 to the right side of the feeding mechanism 1, or the chain plate on the right side of this embodiment can be extended to arrange more products 4. After the product 4 is placed directly on the right side of the feeding mechanism 1, the feeding mechanism 1 continues to operate, and the product 4 will automatically move to the limit position of the elastic limit component 9 on the left. At this time, due to the obstruction of the elastic limit component 9, the bottom of the blocked product 4 and the feeding mechanism 1 move relative to each other. At this time, the number of products 4 blocked on the right side changes from one to two, three, or even more. All products 4 do not need to consider the timing of being placed in the feeding mechanism 1, and the products 4 can be automatically stacked and arranged in sequence. As the material shifting component rotates, each rotation of the shifting plate 7 will carry a corresponding number of products 4 through the elastic limit component. This number can be 1, 2, 3, etc. The longer the shifting plate 7 is, the more products 4 it can carry. However, when more products 4 are moved at the same time, the stability will decrease. Therefore, the number of products 4 generally does not exceed 3, and in such cases, Figure 7When the two paddles 7 are symmetrically arranged as shown, the two paddles 7 must also consider the problem of not wanting to cross when rotating, so the actual length of the paddle 7 is limited; after these products 4 pass through, the subsequent products 4 are automatically added, so as to form a regular reciprocating feeding.

[0040] In this process, referring to Figure 7 and Figure 8 When the plate 7 rotates, the part that interacts with the product 4 is actually only a small part. Therefore, during the process of the plate 7 rotating one circle, there is a part that does not interact with the product 4. During this process, the plate 7 will not carry the product 4 through the elastic limiting component 9, so this process forms a feeding interval. This is suitable for the production method of the production line and can provide sufficient interval time for some processes.

[0041] In order to ensure that the feeding mechanism can stably push the feeding, Figure 3 As shown, the preferred material-pickup mechanism is provided on both sides of the feeding mechanism 1 and is symmetrical to each other. When rotating, the two material-pickup mechanisms on both sides rotate at the same speed and in opposite directions, so that the two paddles 7 on both sides remain symmetrical when rotating. Figure 7 As shown in (a), the upper plate 7 rotates clockwise and the lower plate 7 rotates counterclockwise. When the rotation speeds are the same, the two plates 7 can be kept symmetrical with each other, and stable feeding can be performed. Obviously, when the two plates 7 start to push the product 4, the two plates 7 will also form a cone-shaped configuration, which will act on the product 4 and have a positioning effect on the product 4, ensuring that the product 4 is located between the two plates 7.

[0042] Of course, we can also briefly explain the situation where the material transfer mechanism is only set on one side. Fig.13 , Fig.13 A limiting baffle is set on the other side, and the material shifting assembly is on the other side. When the shifting plate 7 rotates, the product 4 can be moved forward stably. This is one of the simple modified embodiments of the present application.

[0043] Embodiment 3: like Figure 1 , Fig. 9 and Fig.10As shown, the transfer mechanism includes a first clamping part 2 and a second clamping part 3, each of which includes a chain plate and a clamping element 18, the chain plate includes a chain, a support roller, a tensioning roller and a transmission roller, and a driving part 6 is arranged outside the transmission roller, and the support roller, the tensioning roller and the transmission roller make the corresponding chain form a specific configuration; the clamping element 18 is fixed on the chain to form a clamping chain plate. The driving part 6 can select a motor, and the motor drives the chain to rotate, thereby moving the clamping element 18, and the clamping element 18 can move with the product 4 after clamping the product 4. Among them, the chain, the support roller, the tensioning roller and the transmission roller are common structures of the clamping chain conveyor, so their specific structure and principle are not repeated.

[0044] like Figure 5 , Figure 6 As shown, the transmission roller and the driving part 6 are connected by a first transmission sprocket 17 and a synchronous belt. A first driven gear 15 is provided at the bottom of the paddle 7. A combined transmission member 16 is provided on the outer side of the first driven gear 15. The combined transmission member 16 includes a second driven gear at the top and a second transmission sprocket 16c at the bottom. The second driven gear and the first driven gear 15 are meshed. The second transmission sprocket 16c is also provided on the corresponding synchronous belt, so that the second transmission sprocket 16c and the first transmission sprocket 17 move synchronously with the corresponding transmission ratio, thereby making the first driven gear 15 synchronized with the transfer mechanism and move with the corresponding transmission ratio. Figure 5 As shown, the upper one is the second driven gear, and the lower one is the second transmission sprocket 16c. Obviously, according to the basic principle of sprocket transmission, by changing, for example, by setting the gear ratio to adjust the transmission ratio, the second transmission sprocket 16c and the first transmission sprocket 17 can be made to move synchronously with the corresponding transmission ratio. The first transmission sprocket 17 is related to the driving of the corresponding first clamping part 2 and the second clamping part 3, and the second transmission sprocket 16c is related to the rotation of the paddle, so by setting a specific transmission ratio, the paddle 7 can be made to load materials at a specific frequency.

[0045] Further, such as Figure 5As shown, the second driven gear includes a plurality of groups of transmission teeth 16a and a transmission interval 16b which is one less than the number of groups of transmission teeth 16a. The transmission teeth 16a of the second driven gear mesh with the first driven gear 15. After each group of transmission teeth 16a and the first driven gear 15 act, the paddle plate rotates 360°. The transmission interval 16b does not act with the first driven gear 15, so that the paddle plate pauses after each rotation and then continues to rotate, so that the loading interval is increased. The purpose of increasing the loading interval in this embodiment is to allow some processes in the production line that require a longer time to have sufficient interval time to proceed. By adjusting the transmission ratio between the transmission teeth 16a on the first driven gear 15 and the second driven gear, the interval can be adjusted to a certain extent. At the same time, the setting of the proportion of the transmission teeth 16a and the transmission interval 16b on the second driven gear can also adjust the interval. As shown Figure 5 , Figure 6 As shown, Figure 5 The transmission teeth 16a are relatively few and are shown in Figure 6 The first driven gear 15 has a large number of teeth. In actual settings, the number of teeth of each group of transmission teeth 16a on the second driven gear is generally the same as the number of teeth of the first driven gear 15, so that it can be ensured that after each group of transmission teeth 16a rotates, the first driven gear 15 can rotate 360°, thereby facilitating control. Of course, based on this principle, a more complex adjustment form can also be set, for example, after each group of transmission teeth 16a rotates, only the first driven gear 15 is rotated 180°, thereby achieving more functions.

[0046] The driving unit 6 serves as a driving source in this embodiment. Two specific solutions of the driving unit 6 are briefly proposed below.

[0047] (1) Two driving parts 6 are provided corresponding to the first clamping part 2 and the second clamping part 3, and the driving parts 6 are provided with a gearbox 10 correspondingly. The two driving parts 6 are controlled by the electronic control to rotate synchronously. When the driving part 6 is selected as a motor, the principle of the gearbox 10 is easy to understand. It can also be provided with a transmission part 14 for transmission. For example, in this embodiment, the first clamping part 2 and the second clamping part 3 are connected by a first transmission sprocket 17, and the first transmission sprocket 17 can be connected to the transmission part 14. The specific principle is easy to understand and is a common technology in the field, so it will not be described in detail.

[0048] (2) A driving part 6 is provided corresponding to the first clamping part 2 and the second clamping part 3, and a gear set and a gearbox 10 are provided corresponding to the driving part 6. The gear set enables the driving part 6 to simultaneously drive the first clamping part 2 and the second clamping part 3 to operate. The principle of using a driving part 6 to simultaneously drive two parts to move using a gear set is a prior art, so it will not be described in detail.

[0049] Embodiment 4: like Figure 1 , Figure 3, Figure 7 and Figure 8 As shown, the present application proposes a specific implementation scheme of an elastic limiting component 9. The elastic limiting component 9 includes two mounting parts 11 fixedly arranged on both sides of the feeding mechanism 1, such as Figure 3 As shown, the mounting portion 11 is provided with a limiting plate 13 which slides in a direction perpendicular to the feeding direction, a spring 12 is provided between the limiting plate 13 and the inside of the mounting portion 11, and a guide portion is provided at the end of the limiting plate 13 close to the product 4; in the initial state, the spring 12 makes the distance between the two limiting plates 13 on both sides smaller than the outer diameter of the product 4, so that the product 4 and the limiting plate 13 abut against each other; when the plate 7 acts on the product 4, the product 4 acts on the guide portion to move the limiting plate 13 outward and compress the spring 12, thereby allowing the product 4 to pass through, and the spring 12 resets at the moment the product 4 passes through so that the next product 4 is blocked. Of course, the guide portion can be set to fit the arc of the cylindrical bottle body, or it can also be set to an inclined surface or other similar structure with guiding performance.

[0050] The mounting portion 11 specifically includes a plate body fixed by bolts and a sleeve body for limiting the sliding of the plate 13. Two support plates 5 can be arranged on both sides of the feeding mechanism 1 to mount and support various components in this embodiment.

[0051] Reference Figure 7 , Figure 8 As shown, when the plate 7 starts to push the product 4 to load, its initial state is Figure 7 In (a), the plate 7 just contacts the product 4. At this time, both plates 7 move toward the entrance of the transfer mechanism, which will move the product 4 and shrink the limiting plate 13. Figure 7 In (b), as the paddle 7 continues to be pushed, it will pass through Figure 8 (c), (d), and finally come to Figure 8 In the state (e), it is obvious that the subsequent product 4 has been blocked by the reset limiting plate 13, and the paddle 7 will continue to push the product 4 for a distance before leaving the product.

[0052] Embodiment 6: Reference Figure 1 This embodiment provides a preferred solution for the clamping element 18. Figure 1 and Fig.14As shown, the clamping element 18 includes a Y-shaped clamping portion and a mounting portion 11 connected to the chain, the clamping portion is horizontally arranged on the side of the mounting portion 11, the head of the clamping portion is vertical and extends out of the chain to connect with the product 4, and the tail of the clamping portion is fixedly connected to the mounting portion 11. The tail of the clamping portion has two fins, and the head is a fin. The above three fins are interconnected, so the strength of one fin of the head can be slightly increased to a certain extent, and the toughness and deformation capacity of the two fins of the tail can be increased. In this way, when clamping, the fins of the head and the product 4 act on each other, and the fins of the head are not easily damaged because of the increased strength, while the two fins of the tail can relieve external force through deformation, and at the same time provide elastic support to ensure the clamping effect of the clamping part. And as Figure 1 As shown, the present application mentions that after the product is transferred from the feeding mechanism 1 to the transfer mechanism, the transfer mechanism clamps and transfers the product 4. Figure 1 In the process from the feeding mechanism 1 to the transfer mechanism, the entrance of the transfer mechanism has a certain curvature, and the clamping element 18 perpendicular to the chain is inclined. At this time, when the product 4 enters, the flexible fins (the fin part with better toughness) more or less sweep and carry the product until it is firmly clamped between the fins of the relative clamping element 18 to transfer along the transfer trajectory, so the clamping element 18 is easier to clamp.

[0053] Of course, other structures of clamping elements can also be used, such as Fig.12 Another embodiment of the clamping element 18 and the effect of the product 4 is shown.

[0054] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application.
