Description

Technical Field

[0001] This utility model relates to the field of conveyor line stopping technology, specifically to a conveyor line stopping structure with dual drive cooperation. Background Technology

[0002] Accumulating roller conveyor is a type of conveyor line that uses single or double sprockets. This device is suitable for conveying objects such as cartons, pallets, or turnover boxes with flat bottoms, and allows items to stop and accumulate while the drive unit is working. It is commonly used in assembly operations.

[0003] To stop and store items, a blocking structure is generally required. However, existing blocking structures are either installed on the side of a section of the conveyor line or between rollers to stop the conveying process. For example, patent CN205076470U requires a large space between rollers to install this blocking structure.

[0004] In other words, when conveying smaller items and requiring a small distance between each roller and adjacent rollers, the blocking structure of patent CN205076470U requires the removal of several rollers during installation to make room for placement, which can cause small items to fall. Furthermore, the slow lifting and lowering speed of a single-drive blocking structure reduces the efficiency of accumulation and conveying after stopping and releasing. Finally, blocking structures with damping or buffer components may experience damage to the damping or buffer components after a period of blocking, requiring replacement of the entire blocking structure or individual damping or buffer components, thus increasing the cost of use. Therefore, a blocking structure for a dual-drive conveyor line is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the following problems: First, when conveying smaller objects, the stop structure of patent CN205076470U requires the removal of several rollers during installation to make room for placement, which causes small objects to fall and cannot achieve a small distance between each roller and adjacent rollers; second, the slow lifting speed of the single-drive stop structure reduces the accumulation and conveying efficiency after stopping and releasing; third, the damping or buffer components of the stop structure will be damaged after a period of stopping, which requires the replacement of the entire stop structure or individual damping or buffer components, increasing the cost of use. This utility model provides a stop structure for a conveyor line with dual drive cooperation.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A blocking structure on a dual-drive conveyor line includes a roller conveyor line and a blocking component. The roller conveyor line consists of several rollers arranged side by side. The blocking component includes a base portion and a stop portion. The stop portion is inserted between two rollers, and the distance between the two rollers is greater than the horizontal width of the stop portion. A first drive assembly and a second drive assembly are provided. The first drive assembly drives one end of the base portion to move, and the other end moves in a fan shape with the second drive assembly. The second drive assembly includes a first stud, a second stud, and a threaded sleeve. The threaded sleeve is threadedly connected to the first stud and the second stud. When the threaded sleeve rotates clockwise or counterclockwise, the first stud and the second stud rotate counterclockwise or clockwise in the same direction.

[0008] Furthermore, a ball groove is provided on the side of the base near the second drive assembly, and a movable ball is connected to the end of the first stud away from the second stud, the movable ball being inserted into the ball groove.

[0009] Furthermore, a first threaded ring and a second threaded ring are respectively provided on the outer wall and / or inner wall of the first stud and the second stud, and the threaded sleeve is threadedly connected to the first stud and the second stud through the first threaded ring and the second threaded ring.

[0010] Furthermore, an external toothed ring is connected to the outer wall of the threaded sleeve, the external toothed ring is engaged with a drive toothed ring, the drive toothed ring is connected to a drive wheel, the drive wheel is connected to a drive rod, and a power block is connected to the end of the drive rod away from the drive wheel.

[0011] Furthermore, a connecting block is connected to the end of the second stud away from the first stud, and a rotatable disk is connected to one side of the connecting block. The rotatable disk is divided into an inner disk and an outer disk. The diameter of the inner disk is smaller than that of the outer disk, and it rotates with the outer disk as a reference.

[0012] Furthermore, the base portion is provided with a connecting hole and a connecting rod, the connecting rod rotates within the connecting hole, the first drive assembly includes a connector, the connector and the connecting rod are connected, one end of the connector is connected to an inner rod, the inner rod is fitted with an outer cylinder, and the inner rod slides on the inner wall of the outer cylinder.

[0013] Furthermore, the blocking member also includes a buffer section, and a separation space is provided between the base section and the blocking section. The buffer section includes an elastic block, which includes a first block and a second block. One end of the first block and one end of the second block are connected and form an included angle, the included angle being in the range of 20°-80°.

[0014] Furthermore, the side of the first component that is not connected and is close to the second component is provided as a gap and is connected to a spring, with the end of the spring away from the first component connected to the second component.

[0015] Furthermore, a mounting plate is connected to one side of module one and / or module two.

[0016] Furthermore, the mounting plate has at least one through hole, and a screw is inserted into each through hole to connect the mounting plate to the base and / or the retaining part.

[0028] A blocking structure on a dual-drive conveyor line includes a roller conveyor line 1 and a blocking component 2. The roller conveyor line 1 consists of several rollers arranged side by side. The blocking component 2 includes a base part 21 and a stop part 22. The stop part 22 is inserted between two rollers, and the distance between the two rollers is greater than the horizontal width of the stop part 22. A first drive assembly 3 and a second drive assembly 4 are also included. The first drive assembly 3 drives one end of the base part 21 to move, and the other end moves in a fan shape with the second drive assembly 4. The second drive assembly 4 includes a first stud 401, a second stud 402, and a threaded sleeve 403. The threaded sleeve 403 is threadedly connected to the first stud 401 and the second stud 402. When the threaded sleeve 403 rotates clockwise or counterclockwise, the first stud 401 and the second stud 402 rotate in the same direction, either clockwise or counterclockwise.

[0029] like Figure 2 As shown, a ball groove 405 is provided on the side of the base portion 21 near the second drive assembly 4. A movable ball 404 is connected to the end of the first stud 401 away from the second stud 402. The movable ball 404 is inserted into the ball groove 405. The relative position of the movable ball 404 and the base portion 21 will not rotate with the rotation of the sleeve 403. That is, when the sleeve 403 rotates, the first stud 401 will slowly extend a longer length beyond the sleeve 403. The first stud 401 will not rotate with the rotation of the sleeve 403. The movable ball 404 can only rotate in the ball groove 405 in a direction perpendicular to the rotation of the sleeve 403. The limiting component is not shown in the figure. In this way, when one end of the base portion 21 slowly moves downward, a certain relative movement space can be provided between the base portion 21 and the movable ball 404.

[0030] like Figure 5 As shown, a first threaded ring 406 and a second threaded ring 407 are respectively provided on the outer wall and / or inner wall of the first stud 401 and the second stud 402. The threaded sleeve 403 is threadedly connected to the first stud 401 and the second stud 402 through the first threaded ring 406 and the second threaded ring 407. The rotation of the threaded connection of the threaded sleeve 403 causes the first stud 401 and the second stud 402 to extend together away from each other, or it can cause the first stud 401 and the second stud 402 to extend together closer to each other.

[0031] like Figure 5 As shown, an external toothed ring 408 is connected to the outer wall of the threaded sleeve 403. The external toothed ring 408 is meshed with a drive toothed ring 410. The drive toothed ring 410 is connected to a drive wheel 409. The drive wheel 409 is connected to a drive rod 413. The end of the drive rod 413 away from the drive wheel 409 is connected to a power block 414. The power block 414 can make the drive rod 413 rotate and drive the drive wheel 409 to rotate.

[0032] like Figure 5As shown, the end of the second stud 402 away from the first stud 401 is connected to a connecting block 411. One side of the connecting block 411 is connected to a rotatable disk 412, which is divided into an inner disk and an outer disk. The diameter of the inner disk is smaller than that of the outer disk, and it rotates with the outer disk as a reference. The connecting block 411 is connected to the inner disk and can rotate together with the inner disk, ensuring that there is a certain amount of room for movement and rotation when one end of the base part 21 is displaced downward.

[0033] like Figure 4 As shown, a connecting hole and a connecting rod 25 are provided in the base part 21. The connecting rod 25 rotates in the connecting hole. The first drive assembly 3 includes a connector 31, which is connected to the connecting rod 25. One end of the connector 31 is connected to an inner rod 32. An outer cylinder 33 is fitted over the inner rod 32. The inner rod 32 slides on the inner wall of the outer cylinder 33. The inner rod 32 and the outer cylinder 33 form a linear push-pull device, which drives the connector 31 and one end of the base part 21 to move away from the outer cylinder 33 and towards the outer cylinder 33.

[0034] like Figure 3 As shown, the blocking member 2 also includes a buffer part 23. A separation space 24 is provided between the base part 21 and the baffle part 22. The buffer part 23 includes an elastic block 231. The elastic block 231 includes a first block 2311 and a second block 2312. One end of the first block 2311 and one end of the second block 2312 are connected and form an angle. The angle range is 20°-80°. This separation space 24 can effectively insert various types of buffer parts 23 into it. The first block 2311 and the second block 2312 form a certain angle, which plays a buffering role after the baffle part 22 is compressed and pressed down on the second block 2312 after being pushed. The first block 2311 and the second block 2312 can also be made of a material with a certain elasticity.

[0035] like Figure 3 As shown, the side of component 1 2311 that is not connected and is close to component 2 2312 is set as a gap 232, and a spring 233 is connected thereto. The end of the spring 233 away from component 1 2311 is connected to component 2 2312. The spring 233 provides support and elastic force between component 1 2311 and component 2 2312.

[0036] like Figure 3 As shown, a mounting plate 234 is connected to one side of component 1 2311 and / or component 2 2312. The mounting plate 234 limits the position of component 1 2311 and component 2 2312 within the separation space 24 to prevent component 1 2311 and component 2 2312 from falling outward.

[0037] like Figure 3As shown, the mounting plate 234 has at least one through hole, and a screw 235 is inserted into each through hole. The screw 235 connects the mounting plate 234 to the base part 21 and / or the retaining part 22. Alternatively, the mounting plate 234 can be connected to the base part 21 and / or the retaining part 22 by means of pins, adhesive, etc.

[0038] Example 1: When it is necessary to accumulate pallets, products, or parts on roller conveyor line 1, the linear push-pull device composed of outer cylinder 33 and inner rod 32 is activated. The inner rod 32 drives the lower ends of connector 31, connecting rod 25, and base 21 to move closer to outer cylinder 33. At the same time, the power block 414 is activated, causing drive rod 413 to rotate drive wheel 409. Drive toothed ring 410 outside drive wheel 409 and outer toothed ring 408 outside threaded sleeve 403 are engaged, transmitting rotation to threaded sleeve 403. Threaded sleeve 403 will also rotate. Because threaded sleeve 403 is threadedly connected to first threaded ring 406 and second threaded ring 407, that is, through threaded transmission, the first threaded ring 406 rotates. Both stud 401 and stud 402 extend outwards. At this time, the distance between the first stud 401, the second stud 402, and the threaded sleeve 403 increases, which in turn increases the distance between the base part 21 and the connecting block 411. This causes the upper part of the base part 21 to move in a fan shape, and the baffle part 22 exceeds the height of the roller, blocking the pallets, products, or parts on the conveyor line to achieve an accumulation effect. When it is necessary to release, the linear push-pull device and the power block 414 are activated to move the connecting head 31 away from the outer cylinder 33, so that the distance between the first stud 401, the second stud 402, and the threaded sleeve 403 decreases.

[0039] Example 2: When the baffle 22 blocks the pallets, products or parts on the conveyor line, some of the impact force needs to be buffered. Therefore, the gap 232 between the first block 2311 and the second block 2312 in the separation space 24 has a certain angle and is equipped with a spring 233 to provide a buffering feeling when the first block 2311 is subjected to the downward pressure of the baffle 22. When the buffer part 23 is damaged, it can be replaced individually, reducing the time and cost of replacing the entire blocking structure.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
