Description

Technical Field

[0001] This invention relates to the field of automated production lines, and more specifically to an intermittent rotating material tray. Background Technology

[0002] After a large batch of small cylindrical products are produced on an assembly line, they are usually randomly aggregated together. If subsequent secondary processing, assembly, and testing of each product are required, they need to be picked up one by one. Whether using manpower or robotic arms, the cost is high. A different low-cost and efficient method is needed. Summary of the Invention

[0003] The problem to be solved by the present invention is to provide an intermittent rotating material tray, which realizes the turntable station with low equipment cost, realizes the intermittent transfer of products, and the transfer action is fast and reliable.

[0004] To solve the above problems, the present invention provides an intermittent rotating feeder. To achieve the above objectives, the technical solution adopted by the present invention to solve its technical problems is as follows:

[0005] An intermittent rotating material tray includes: a rotating tray having a rotational degree of freedom about its own axis, with a plurality of notches spaced apart on its edge for accommodating products; a vibrating plate that contacts the rotating tray via a conveying track, the vibrating plate conveying products to the rotating tray; and a transmission belt that contacts the edge of the rotating tray, with a drive motor, a first driven pulley, and a second driven pulley in contact with its inner wall. The transmission belt has one arc segment and two straight segments except for the portions contacting the drive motor, the first driven pulley, and the second driven pulley. The arc segment between the first and second driven pulleys contacts the edge of the rotating tray and the products within the notches, while the straight segments between the first and second driven pulleys and the drive motor are respectively the arc segment. One end of the arc segment contacts the output end of the conveying track, and the drive motor drives the rotating tray to rotate intermittently using the transmission belt.

[0006] The beneficial effects of adopting the above technical solution are as follows: The active motor provides the main power for the rotation of the transmission belt and the rotating disc. The arc segment and the straight segment are not fixed segments on the transmission belt, but are limited by the active motor, the first driven pulley, and the second driven pulley. The positions of the arc segment and the straight segment on the transmission belt change in real time. On the one hand, the arc segment contacts the rotating disc, applying rotational force to it. The contact length between the arc segment and the rotating disc is sufficient to ensure that the rotating disc rotates synchronously. On the other hand, the arc segment effectively seals the openings of the upper part of the rotating disc, clamping and limiting the products within these openings, ensuring that the products do not loosen despite the intermittent rotation of the rotating disc. The vibratory feeder pushes the products into the openings not sealed by the transmission belt through the feeding track, and then the arc segment of the transmission belt seals them, limiting the products. The products rotate intermittently on the rotating disc, which is equivalent to forming a rotating workstation, facilitating external equipment to process and inspect the products. It can also achieve the effect of discharging products one by one.

[0007] As a further improvement of the present invention, the notches are arranged in a ring array around the axis of the rotating material tray, and the opening of the notch is transitioned to the edge of the rotating material tray by an outer rounded corner.

[0008] The beneficial effect of adopting the above technical solution is that the outer rounded corners increase the width of the opening, making it easier for products to enter and exit.

[0009] As a further improvement of the present invention, the outer contour of the product is cylindrical, and the depth of the notch is not greater than the diameter of the product.

[0010] The beneficial effects of adopting the above technical solution are: the outer circumferential surface of the cylinder contacts the inner wall of the notch, and due to the depth of the notch, the outer circumferential surface of the cylinder also contacts the arc segment of the conveyor belt. Due to the dual effect of the arc segment and the notch, the product can be limited on the notch and rotate with the material transfer plate.

[0011] As a further improvement of the present invention, the number of notches is not less than five.

[0012] The beneficial effect of adopting the above technical solution is to ensure the number of gaps corresponding to the arc segment, thereby ensuring the number of products intermittently conveyed per unit time.

[0013] As a further improvement of the present invention, the center line of the arc segment is a semi-circular arc.

[0014] The beneficial effects of adopting the above technical solution are: ensuring that the arc segment on the conveyor belt can contact half of the edge of the transfer tray, ensuring that the arc segment can correspond to several notches, thereby limiting several products.

[0015] As a further improvement of the present invention, the arc segment contacts the output track at the end away from the material conveying track, the center line of the material conveying track intersects the circle containing the edge of the rotating disk, and the center line of the output track is tangent to the circle containing the edge of the rotating disk.

[0016] The beneficial effects of adopting the above technical solution are as follows: For the transfer tray, the feeding track and the output track are one for feeding and one for discharging, realizing the continuous feeding and discharging of products. The orientation of the feeding track determines that it can use a certain thrust to send the product into the notch, and the product about to come out of the transfer tray can be received by the tangent output track due to its own trajectory.

[0017] As a further improvement of the present invention, the axes of the transfer disc, the first driven wheel, and the second driven wheel are all vertical, while the length direction of the conveying track and the output track is horizontal.

[0018] The beneficial effect of adopting the above technical solution is that the product as a whole is transferred and transported in a horizontal plane, avoiding the adverse effects of gravity.

[0019] As a further improvement of the present invention, one end of the cylinder of the product has a convex shaft, and the output track is composed of a first type strip and a second type strip arranged in parallel to each other. The cross-sectional profile of the first type strip and the second type strip is L-shaped. The first type strip and the second type strip are both composed of a bottom strip and a side strip that are vertically fixed. A gap is formed between the bottom strips of the first type strip and the second type strip, and the gap allows the convex shaft to pass through.

[0020] The advantages of adopting the above technical solution are: the gap facilitates the accommodation and passage of the convex shaft at the bottom of the product; the first and second type strips are equivalent to channel steel structures and have sufficient strength; the bottom strip supports the bottom shaft end of the product; and the side strips limit the movement of the product's sides.

[0021] As a further improvement of the present invention, the bottom strips of the first type strip and the second type strip each have a flared opening at the end near the transfer plate.

[0022] The beneficial effects of adopting the above technical solution are: the flared mouth makes it easier to increase the opening width of the gap at the end, which facilitates the guidance of the bottom convex shaft of the product output from the transfer tray into the gap and into the output track.

[0023] As a further improvement of the present invention, the length of the side strip of the first type strip is greater than the length of the side strip of the second type strip, and the bottom strip of the second type strip is located below the transfer tray. The vertical projection of the transfer tray only contacts the bottom strip of the second type strip and does not contact the bottom strip of the first type strip.

[0024] The beneficial effects of adopting the above technical solution are: the length of the side strip of the second type of strip is shortened to prevent interference with the transfer tray, and the bottom strip of the second type of strip is inserted into the bottom of the transfer tray to catch the product output from the notch on the transfer tray as soon as possible.

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to specific embodiments:

[0033] To achieve the purpose of this invention, an intermittent rotating material tray includes: a rotating tray 8 having rotational freedom about its own axis, and a plurality of notches 8a for accommodating products 3 arranged at intervals on the edge of the rotating tray 8; a vibrating plate 1, which contacts the rotating tray 8 via a feeding track 2, and the vibrating plate 1 feeds products 3 to the rotating tray 8; and a transmission belt 6, which contacts the edge of the rotating tray 8, and the inner wall of the transmission belt 6 contacts a drive motor 7, a first driven pulley 4, and a second driven pulley 5. In addition to the contact with the drive motor, the transmission belt 6 also has other components. 7. The contact points of the first driven wheel 4 and the second driven wheel 5 form an arc segment 6b and two straight segments 6a; the transmission belt 6 between the first driven wheel 4 and the second driven wheel 5 is an arc segment 6b that contacts the edge of the rotating disc 8 and the product 3 in the notch 8a, and the transmission belt 6 between the first driven wheel 4 and the second driven wheel 5 and the drive motor 7 is a straight segment 6a; one end of the arc segment 6b contacts the output end of the conveying track 2, and the drive motor 7 uses the transmission belt 6 to drive the rotating disc 8 to rotate intermittently.

[0034] The transmission belt 6 itself is flexible and elastic. Its curved segment 6b and straight segment 6a are limited by the active motor 7, the first driven pulley 4, and the second driven pulley 5, which are fixed in spatial position to each other.

[0035] The beneficial effects of adopting the above technical solution are as follows: The active motor provides the main power for the rotation of the transmission belt and the rotating disc. The arc segment and the straight segment are not fixed segments on the transmission belt, but are limited by the active motor, the first driven pulley, and the second driven pulley. The positions of the arc segment and the straight segment on the transmission belt change in real time. On the one hand, the arc segment contacts the rotating disc, applying rotational force to it. The contact length between the arc segment and the rotating disc is sufficient to ensure that the rotating disc rotates synchronously. On the other hand, the arc segment effectively seals the openings of the upper part of the rotating disc, clamping and limiting the products within these openings, ensuring that the products do not loosen despite the intermittent rotation of the rotating disc. The vibratory feeder pushes the products into the openings not sealed by the transmission belt through the feeding track, and then the arc segment of the transmission belt seals them, limiting the products. The products rotate intermittently on the rotating disc, which is equivalent to forming a rotating workstation, facilitating external equipment to process and inspect the products. It can also achieve the effect of discharging products one by one.

[0036] In other embodiments of the present invention, the notches 8a are arranged in a ring array around the axis of the rotating material tray 8, and the opening of the notches 8a is connected to the edge of the rotating material tray 8 by an outer rounded corner.

[0037] The beneficial effect of adopting the above technical solution is that the outer rounded corners increase the width of the opening, making it easier for products to enter and exit.

[0038] In some other embodiments of the present invention, the outer contour of product 3 is cylindrical, and the depth of the notch 8a is not greater than the diameter of product 3.

[0039] The beneficial effects of adopting the above technical solution are: the outer circumferential surface of the cylinder contacts the inner wall of the notch, and due to the depth of the notch, the outer circumferential surface of the cylinder also contacts the arc segment of the conveyor belt. Due to the dual effect of the arc segment and the notch, the product can be limited on the notch and rotate with the material transfer plate.

[0040] In some other embodiments of the invention, the number of notches 8a is not less than five.

[0041] The beneficial effect of adopting the above technical solution is to ensure the number of gaps corresponding to the arc segment, thereby ensuring the number of products intermittently conveyed per unit time.

[0042] In some other embodiments of the present invention, the center line of the arc segment 6b is a semi-circular arc.

[0043] The beneficial effects of adopting the above technical solution are: ensuring that the arc segment on the conveyor belt can contact half of the edge of the transfer tray, ensuring that the arc segment can correspond to several notches, thereby limiting several products.

[0044] In some other embodiments of the present invention, the arc segment 6b contacts the output track 9 at one end away from the material conveying track 2, the center line of the material conveying track 2 intersects the circle containing the edge of the rotating disk 8, and the center line of the output track 9 is tangent to the circle containing the edge of the rotating disk 8.

[0045] The beneficial effects of adopting the above technical solution are as follows: For the transfer tray, the feeding track and the output track are one for feeding and one for discharging, realizing the continuous feeding and discharging of products. The orientation of the feeding track determines that it can use a certain thrust to send the product into the notch, and the product about to come out of the transfer tray can be received by the tangent output track due to its own trajectory.

[0046] In other embodiments of the present invention, the axes of the transfer disc 8, the first driven wheel 4, and the second driven wheel 5 are all vertical, and the length directions of the conveying track 2 and the output track 9 are horizontal.

[0047] The beneficial effect of adopting the above technical solution is that the product as a whole is transferred and transported in a horizontal plane, avoiding the adverse effects of gravity.

[0048] In some other embodiments of the present invention, one end of the cylinder of product 3 is provided with a convex shaft, and the output track 9 is composed of a first type strip 9b and a second type strip 9c arranged in parallel to each other. The cross-sectional profile of the first type strip 9b and the second type strip 9c is L-shaped. The first type strip 9b and the second type strip 9c are both composed of a bottom strip and a side strip that are vertically fixed. A gap 9a is formed between the bottom strips of the first type strip 9b and the second type strip 9c, and the gap 9a allows the convex shaft to pass through.

[0049] The advantages of adopting the above technical solution are: the gap facilitates the accommodation and passage of the convex shaft at the bottom of the product; the first and second type strips are equivalent to channel steel structures and have sufficient strength; the bottom strip supports the bottom shaft end of the product; and the side strips limit the movement of the product's sides.

[0050] In some other embodiments of the present invention, the bottom strips of the first type strip 9b and the second type strip 9c each have a flared opening 9d at one end near the transfer tray 8.

[0052] In other embodiments of the invention, such as Figure 4 , Figure 5 As shown, the length of the side strip of the first type 9b is greater than the length of the side strip of the second type 9c. The bottom strip of the second type 9c is located below the transfer plate 8. The vertical projection of the transfer plate 8 only contacts the bottom strip of the second type 9c and does not contact the bottom strip of the first type 9b.

[0053] The beneficial effects of adopting the above technical solution are: the length of the side strip of the second type of strip is shortened to prevent interference with the transfer tray, and the bottom strip of the second type of strip is inserted into the bottom of the transfer tray to catch the product output from the notch on the transfer tray as soon as possible.
