Description

Technical Field

[0001] The present invention relates to the technical field of product conveying, and in particular to a conveying device. Background Art

[0002] In the production and transportation process of existing products, in order to improve the efficiency of product production and reduce labor costs, a conveying device is often set between two adjacent processes to automatically transport the product from the previous process to the next process. Some conveying devices are equipped with upper and lower layers of rollers. When conveying products, the products are located between the upper and lower layers of rollers and clamped by the upper and lower layers of rollers, so that the rollers can pull the products to move when they rotate, thereby conveying the products to the next process.

[0003] However, the products on the same production line have different shapes and sizes. For example, glass fiber profiles have various shapes, such as cross, T-shaped, I-shaped, etc. When the roller clamps glass fiber profiles of different shapes, it cannot ensure that the roller is in close contact with the surface of all glass fiber profiles, so that the glass fiber profile cannot be effectively clamped, affecting the traction effect of the conveying device on the glass fiber profile.

[0047] like Figures 1 to 6 As shown, this embodiment provides a conveying device that can be adapted to stably clamp and convey products 100 of various shapes, thereby expanding the versatility of the conveying device.

[0048] See also Figure 1 The conveying device includes a support frame 1, a first roller 2, a second roller 3, a driving assembly, a plurality of clamping assemblies 4 and a pressure mechanism. The first roller 2 and the second roller 3 are both rotatably arranged on the support frame 1, and the first roller 2 and the second roller 3 are moved in a preset direction ( Figure 1 The first roller 2 and the second roller 3 are arranged at intervals, and the product 100 to be conveyed can extend between the first roller 2 and the second roller 3; the driving component is arranged on the support frame 1, and is used to drive the first roller 2 and the second roller 3 to rotate; a plurality of groups of clamping components 4 are arranged at intervals along the circumference of the first roller 2, and the clamping component 4 includes a clamping member 41 movably arranged on the first roller 2 along the radial direction of the first roller 2, and the clamping member 41 can rotate relative to the first roller 2; the pressure mechanism is used to apply pressure along the radial direction of the first roller 2 to the clamping component 4; when the first roller 2 and the second roller 3 rotate, the first roller 2 can drive the clamping component 4 to rotate together, so that the clamping member 41 contacts or separates from the product 100, when the clamping member 41 contacts the product 100, the clamping member 41 pushes the product 100 to fit with the second roller 3 under the action of the pressure mechanism, and at the same time, the product 100 can push the clamping member 41 in the opposite direction to rotate until it is pressed and fit with the product 100, and the clamping member 41 can cooperate with the second roller 3 to drive the product 100 along the conveying direction ( Figure 1 The preset direction is perpendicular to the transmission direction.

[0049] In the conveying device provided in this embodiment, the product 100 is located between the first roller 2 and the second roller 3 for conveying. When the first roller 2 rotates, it can drive the clamping assembly 4 to rotate together. The first roller 2 drives the clamping member 41 to move along its circumferential direction. When the clamping member 41 gradually approaches the product 100 and contacts the product 100, the clamping member 41 can push the product 100 to fit the second roller 3 under the pressure of the pressure mechanism, that is, the clamping member 41 converts the pressure it receives into a thrust force on the product 100, and the pressure generated by the pressure mechanism can keep the clamping member 41 in contact with the product 100. At this time, the product 100 is clamped between the first roller 2 and the second roller 3 under the thrust force of the clamping member 41 on one side and the supporting force of the second roller 3 on the other side and has a tendency to rotate. The force driving the product 100 to rotate can drive the product 100 to move along the tangent direction of the first roller 2, that is, the conveying direction, thereby realizing the conveying of the product 100. A plurality of clamping assemblies 4 are arranged at intervals along the circumference of the first roller 2, so that after the previous clamping member 41 is separated from the product 100, the product 100 can contact with the next clamping member 41, and the product 100 is subjected to continuous traction, thereby achieving stable clamping and conveying of the product 100. In addition, the clamping member 41 can adjust its distance from the surface of the product 100 by moving radially along the first roller 2 under pressure, so that the clamping member 41 can adaptively contact with products 100 of different specifications; after the clamping member 41 contacts the product 100, the product 100 can push the clamping member 41 in the opposite direction to rotate to press and fit with the product 100, thereby adjusting the contact angle between the clamping member 41 and the product 100, increasing the contact area between the product 100 and the clamping member 41, so that the clamping member 41 can adaptively adjust the clamping angle according to the shape of the product 100, expanding the versatility of the conveying device, and ensuring the clamping effect of the clamping member 41 on the product 100.

[0050] Specifically, see Figure 1In the orientation, after the product 100 extends from the left side of the support frame 1 into between the first roller 2 and the second roller 3, the first roller 2 and the second roller 3 rotate, and the first roller 2 can drive the clamping member 41 to move along its circumferential direction, and the clamping member 41 moves between the first roller 2 and the product 100, so that the clamping member 41 gradually contacts with the product 100; after the clamping member 41 contacts with the product 100, the clamping member 41 pushes the product 100 under the pressure of the pressure mechanism, and the product 100 fits with the second roller 3, so that the product 100 is clamped between the clamping member 41 and the second roller 3; at the same time, the clamping member 41 is subjected to the reverse thrust of the product 100, and the pressure on the clamping member 41 is less than the reverse thrust, so that the clamping member 41 rotates relative to the first roller 2 and moves toward the center of the first roller 2, so as to adjust the angle and distance between the clamping member 41 and the product 100, and ensure that the clamping member 41 can be suitable for clamping products 100 of different shapes. In the above process, the first roller 2 and the second roller 3 are always in a state of continuous rotation, and the product 100 has a tendency to rotate under the clamping action of the clamping member 41 and the second roller 3. At this time, the force driving the product 100 to rotate can drive the product 100 to move along the conveying direction, thereby enabling the product 100 to move along the conveying direction to the right side of the support frame 1. The first roller 2 continues to rotate, and the clamping member 41 will rotate out from between the first roller 2 and the product 100 and gradually separate from the product 100. The product 100 is no longer clamped by the clamping member 41. At the same time, the next clamping member 41 moves to contact with the product 100 and can continue to clamp the product 100 to stably convey the product 100. In the process of the clamping member 41 and the product 100 gradually separating, the contact area between the product 100 and the clamping member 41 gradually decreases, the clamping member 41 rotates relative to the first roller 2, and the reverse thrust of the product 100 on the clamping member 41 gradually decreases. Under the pressure of the pressure mechanism, the clamping member 41 moves away from the center of the first roller 2 to facilitate the next clamping of the product 100. In this embodiment, the preset direction is the height direction of the support frame 1, and the conveying direction is the width direction of the support frame 1.

[0051] Furthermore, the rotation directions of the first roller 2 and the second roller 3 are opposite, so that the directions of the traction forces applied by the clamping member 41 and the second roller 3 to the product 100 are the same, which is more conducive to driving the product 100 to move; the size, structure and rotation speed of the first roller 2 and the second roller 3 are the same, so that there will be no relative rotation between the first roller 2 and the second roller 3, and both the first roller 2 and the second roller 3 can apply traction to the product 100 to drive it to move, thereby ensuring the traction effect on the product 100.

[0052] For example, see Figure 1 When the product 100 is transferred from the left side to the right side of the support frame 1, the first roller 2 is driven to rotate counterclockwise and the second roller 3 is driven to rotate clockwise.

[0053] In this embodiment, six groups of clamping assemblies 4 are arranged along the circumference of the first roller 2, and the angles between any two adjacent groups of clamping assemblies 4 are the same, so as to ensure that the traction force exerted on the product 100 is continuous and stable.

[0054] Further, see Figure 1 , along the axial direction of the first roller 2 ( Figure 1 A plurality of clamping assemblies 4 are also provided in the Y direction in order to stably clamp the product 100 along the width direction of the product 100 and ensure the stability of the product 100 during transportation.

[0055] Optionally, see Figure 1 and Figure 2 The first roller 2 is provided with a plurality of sliding cavities 21 extending in the radial direction thereof, and the clamping assembly 4 further includes a sliding rod 42. The plurality of sliding cavities 21 correspond to the plurality of sliding rods 42 of the clamping assembly 4 one by one, one end of the sliding rod 42 is rotatably connected with the corresponding clamping member 41, and the other end extends into the corresponding sliding cavity 21 and slidably cooperates with the corresponding sliding cavity 21, and the pressure of the pressure mechanism is applied to the other end of the sliding rod 42. Such a configuration enables the sliding rod 42 to move along the extension direction of the sliding cavity 21 under the pressure of the pressure mechanism, thereby driving the clamping member 41 to move along the radial direction of the first roller 2; the sliding rod 42 is rotatably connected with the clamping member 41 so that the clamping member 41 can rotate relative to the first roller 2.

[0056] Specifically, see Figure 1 When the first roller 2 is in the middle position, the clamping member 41 is not in contact with the product 100, the slide bar 42 slides under the pressure to the position where its rod is completely extended out of the slide cavity 21; when the first roller 2 rotates to the right end of the clamping member 41 and contacts the product 100, the clamping member 41 pushes the product 100 under the pressure, and the clamping member 41 rotates relative to the slide bar 42 under the action of the reverse thrust and drives the slide bar 42 to move in the direction close to the center of the first roller 2; the clamping member 41 continues to move along the circumference of the first roller 2, and the clamping member 41 will contact the product 100 from the right end to the left end, and the clamping member 41 is always in contact with the product 100 under the pressure. They push against each other; when the left end of the clamping member 41 contacts the product 100, the surface of the clamping member 41 is completely fitted with the surface of the product 100, which increases the contact area between the clamping member 41 and the product 100, and is more conducive to the clamping member 41 clamping the product 100 and pulling the product 100 to move; when the first roller 2 rotates until the distance from the end where the slide bar 42 and the clamping member 41 are connected to the surface of the product 100 is greater than the thickness of the clamping member 41, the clamping member 41 gradually separates from the product 100, the clamping member 41 rotates relative to the slide bar 42 and moves in a direction away from the center of the first roller 2, and the clamping member 41 separates from the product 100 in the direction from the right end to the left end.

[0057] In this embodiment, refer to Figure 2 and Figure 3 A first connecting ear plate 411 is provided on the side of the clamping member 41 facing away from the product 100, and a second connecting ear plate 421 is provided on one end of the slide rod 42 connected to the clamping member 41. The pin passes through the first connecting ear plate 411 and the second connecting ear plate 421 to realize the rotational connection between the clamping member 41 and the slide rod 42.

[0058] Exemplarily, the clamping member 41 is a strip-shaped clamping plate.

[0059] In an alternative embodiment, see Figure 1 and Figure 4 The first roller 2 is provided with a connecting cavity 22, and a plurality of sliding cavities 21 are all connected to the connecting cavity 22. The pressure mechanism includes a pressure medium, a pressure pump 51 and a connecting pipe 53. One end of the connecting pipe 53 is connected to the pressure pump 51, and the other end is connected to the connecting cavity 22. The pressure pump 51 is configured to generate a pressure medium, and the pressure medium is delivered to the connecting cavity 22 via the connecting pipe 53 and squeezes the sliding rod 42. After the pressure pump 51 passes the pressure medium into the sliding cavity 21, the pressure in the sliding cavity 21 increases, and the sliding rod 42 can move in a direction away from the first roller 2 under the pressure, and the rod portion of the sliding rod 42 can be kept in a position fully extended from the sliding cavity 21 under the action of pressure, so that when the clamping member 41 contacts the surface of the product 100 of different specifications, the clamping member 41 can move to a suitable position under the reverse push of the product 100, so that the clamping member 41 can adapt to the clamping of products 100 of various specifications. The connecting cavity 22 connects the multiple sliding cavities 21 to each other so that the pressure values ​​in the multiple sliding cavities 21 can be the same, so that the multiple clamping members 41 can apply the same thrust to the product 100, avoiding the situation that the thrust of individual clamping members 41 is too small, causing slippage between the clamping members 41 and the product 100, or the thrust of individual clamping members 41 is too large, damaging the product 100, and also facilitating the pressure pump 51 to pass the pressure medium into multiple sliding cavities 21 at the same time.

[0060] Furthermore, the pressure pump 51 is also provided with a pressure detection member 52 to detect the pressure in the slide cavity 21 and ensure the balance of the pressure in the slide cavity 21. During the contact between the clamping member 41 and the product 100, the pressure on the slide bar 42 is balanced with the reverse thrust of the product 100, and the magnitude of the thrust applied by the clamping member 41 to the product 100 can be confirmed and controlled by controlling the pressure. For example, the greater the pressure value, the greater the thrust applied by the clamping member 41 to the product 100.

[0061] Exemplarily, the pressure pump 51 is a fluid pressurizing device, such as a water pump, and the pressure medium is liquid. A connecting pipe 53 is also provided between the pressure pump 51 and the slide cavity 21 to transport the liquid from the pressure pump 51 to the slide cavity 21. In other embodiments, the pressure pump 51 is a gas pressurizing device, such as an air booster pump, and the pressure medium is gas. A connecting pipe 53 is also provided between the pressure pump 51 and the slide cavity 21 to transport the gas from the pressure pump 51 to the slide cavity 21.

[0062] In another optional embodiment, the pressure mechanism includes a plurality of elastic members, and the plurality of elastic members correspond one-to-one to the plurality of sliding cavities 21. One end of the elastic member is connected to the inner wall of the sliding cavity 21, and the other end is connected to the sliding rod 42. When the clamping member 41 contacts the product 100, the elastic member accumulates elastic potential energy and squeezes the sliding rod 42 along the radial direction of the first roller 2 to ensure that the clamping member 41 can maintain contact with the product 100.

[0063] Specifically, when the clamping member 41 is not in contact with the product 100, the elastic member is not deformed. After the clamping member 41 is in contact with the product 100, the product 100 pushes the clamping member 41 in the reverse direction to move toward the center of the first roller 2, and the elastic member is compressed. At this time, the elastic force of the elastic member acts on the slide bar 42 in the direction away from the center of the first roller 2, that is, the elastic member applies a pressure in the opposite direction of the reverse thrust to the clamping member 41 through the slide bar 42, so that the clamping member 41 can push the product 100.

[0064] Exemplarily, the elastic member is a spring.

[0065] Optionally, see Figure 2 A limiting member 43 is provided at one end of the slide rod 42 located in the slide cavity 21. When the pressure medium drives the slide rod 42 to move, the limiting member 43 can move to abut against the inner wall of the slide cavity 21 to limit the slide rod 42 in the slide cavity 21, so that the rod portion of the slide rod 42 will not fall out of the slide cavity 21, thereby ensuring the normal operation of the conveying device.

[0066] In this embodiment, an opening is provided on the bottom cavity wall of the sliding cavity 21 at one end away from the center of the first roller 2, and the sliding rod 42 moves through the opening. The limiting member 43 is a piston that contacts and slides with the side cavity wall of the sliding cavity 21, and the cross-sectional size of the piston is larger than the size of the opening, so that the piston cannot pass through the opening; the pressure medium can drive the piston to move in a direction away from the center of the first roller 2 until the bottom cavity wall of the sliding cavity 21 with the opening abuts against the piston, thereby achieving the limitation of the sliding rod 42.

[0067] In other embodiments, a limiting hole is provided on the side cavity wall of the sliding cavity 21, and the limiting hole is located at the end of the sliding cavity 21 away from the center of the first roller 2. The limiting member 43 includes a limiting rod and a spring. A groove is provided on the side wall of the sliding rod 42, and the spring is located in the groove. One end of the limiting rod moves through the groove and abuts against the spring. When the limiting member 43 moves to the limiting hole, the other end of the limiting rod can be inserted into the limiting hole to achieve the limitation of the sliding rod 42; when the product 100 pushes the clamping member 41 in the reverse direction, the sliding rod 42 is also subjected to a reverse thrust. Under the action of this thrust, an extrusion force is also generated between the limiting rod and the limiting hole along the extension direction of the sliding cavity 21, causing the spring to undergo elastic deformation along its extension direction, so that the depth of the limiting rod inserted in the limiting hole gradually decreases and disengages from the limiting hole, and the sliding rod 42 can move toward the center of the first roller 2.

[0068] Furthermore, a spherical surface is provided at one end of the limiting rod that is inserted into the limiting hole. The limiting rod can slide into the limiting hole through the spherical surface under the elastic force of the spring. The design of the spherical surface is more conducive to the limiting member 43 being inserted into and out of the limiting hole.

[0069] Optionally, see Figure 1 and Figure 3 The clamping assembly 4 also includes an elastic reset member 44, which is restricted between the clamping member 41 and the sliding rod 42. When the clamping member 41 moves to contact the product 100, the clamping member 41 can rotate relative to the sliding rod 42 under the push of the product 100, and the elastic reset member 44 accumulates elastic potential energy; when the clamping member 41 moves to separate from the product 100, the clamping member 41 can be lifted off the product 100 under the elastic force of the elastic reset member 44. When the elastic reset member 44 is not provided, the clamping member 41 and the slide bar 42 are in a state of free rotation, and the clamping member 41 rotates only under the action of the reverse thrust of the product 100; after the elastic reset member 44 is provided, when the clamping member 41 moves to gradually separate from the product 100, the clamping member 41 can rotate under the elastic force of the elastic reset member 44, so that the clamping member 41 is lifted off the product 100 in the order from the first end to the second end, that is, the provision of the elastic reset member 44 makes the clamping member 41 have a tendency to separate from the product 100, and accelerates the separation rate of the clamping member 41 from the product 100, preventing the clamping member 41 from being stuck on the product 100, and avoiding damage to the product 100 or the conveying device. Among them, the first end and the second end are the two ends of the clamping member 41 along its extension direction, and the first end contacts the product 100 first.

[0070] In this embodiment, refer to Figure 1 When the clamping member 41 is not in contact with the product 100, the angle between the second end of the clamping member 41 and the slide bar 42 is an obtuse angle; in other embodiments, when the clamping member 41 is not in contact with the product 100, the angle between the clamping member 41 and the slide bar 42 can also be a right angle.

[0071] Exemplarily, the elastic return member 44 is a flexible spring plate or a spring.

The output end of the first rotating driving member 61 is connected to the first roller 2 for driving the first roller 2 to rotate. The output end of the second rotating driving member 62 is connected to the second roller 3 for driving the second roller 3 to rotate.

One end of the first telescopic member 81 is fixed to the support frame 1, and the other end is fixedly connected to the first connecting plate 11. When the first telescopic member 81 is extended and retracted, the first telescopic member 81 drives the first connecting plate 11 to move along the preset direction.

[0081] Further, see Figure 5 When multiple second rollers 3 are provided, a second connecting plate 13 is also provided on the support frame 1. The roller of the second roller 3 is passed through the second connecting plate 13 and can rotate relative to the second connecting plate 13. Two slide grooves 12 are arranged on the support frame 1 along the transmission direction. The slide grooves 12 extend along the preset direction.

The second connecting plate 13 slides along the slide groove 12 and drives all the second rollers 3 to move along the preset direction.

[0082] In another alternative embodiment, see Figure 5 The support frame 1 is provided with a first telescopic member 81 and a second telescopic member 82, which further expands the adjustment range of the distance between the first roller 2 and the second roller 3 and expands the versatility of the conveying device.

[0083] In this embodiment, the first telescopic member 81 and the second telescopic member 82 are both electric push rods, and after the electric push rods are turned on, the electric push rods can automatically extend and retract.

[0085] In this embodiment, the anti-skid member 45 includes a plurality of anti-skid teeth arranged at intervals along the extending direction of the clamping member 41, which not only reduces the production cost, but also when the clamping member 41 contacts the product 100, an adsorption cavity filled with air can be formed between the clamping member 41, the product 100 and two adjacent anti-skid teeth, providing additional grip and more effectively preventing sliding. In other embodiments, the anti-skid member 45 can also be an anti-skid pad, which is laid on the side of the clamping member 41 that contacts the product 100.
