Description

Technical Field

[0001] The invention relates to the technical field of conveyors, and in particular to a flexible turning conveyor and a working method thereof. Background Art

[0002] Flexible curve conveyor is a kind of conveying equipment designed for material diversion and transmission in a small space. It can flexibly change the conveying direction and adapt to various complex site layouts. This type of conveyor is widely used in manufacturing, logistics, food processing and other industries, especially in situations where efficient use of space and precise control of material flow are required.

[0003] A heavy-duty turning chain plate conveyor is disclosed in the patent document with the announcement number CN 219116364 U, which includes a frame, a right-angle bending track frame is fixed on the top of the frame, and a turning chain plate conveyor assembly is installed inside the right-angle bending track frame, a flexible bending plate is arranged on the bending track line at the top of the right-angle bending track frame, and a plurality of right-angle fixing seats are bolted and fixed on the outer walls of both sides of the right-angle bending track frame. The heavy-duty turning chain plate conveyor is provided with a flexible bending plate and a right-angle fixing seat and other structures that cooperate with each other. The flexible bending plate shields and protects heavy materials on the bending track line at the top of the right-angle bending track frame, thereby preventing the materials from deviating from the track and falling out.

[0004] Although the flexible curved plates provided on the above-mentioned conveyor can shield and protect the materials and prevent them from leaving the track, when the materials are transported to the turning point, the chain plates will rotate relative to each other, causing the position of the materials on the chain plates to change. When the materials have completely passed the turning point, the position of the materials relative to the chain plates where the raw materials are located will deviate, resulting in a decrease in the conveying accuracy of the conveyor for the materials. In addition, when the materials are transported to the turning point, the materials are prone to sliding on the chain plates due to inertia, causing the materials to further deviate from the chain plates where the raw materials are located, resulting in a further decrease in the conveying accuracy of the conveyor for the materials, which greatly reduces the conveying accuracy of the conveyor for the materials. To this end, we propose a flexible turning conveyor and a working method thereof. Summary of the invention

[0019] Preferably, the first spring and the second spring are both in an extended state.

[0020] A working method of a flexible curve conveyor comprises the following steps:

[0021] S1. When in use, multiple pallet assemblies are installed on the conveyor belt according to the conveying requirements;

[0022] S2. During the installation process, the magnet plate at the bottom of the chassis is inserted into the multiple adsorption plates, so that the magnet plate is adsorbed on the adsorption plates, and the first ball on the connecting seat at the bottom of the chassis is placed on the magnet assembly, so that the magnet assembly and the first ball are adsorbed;

[0023] S3, starting the power assembly, the power assembly drives the conveyor belt, placing the objects to be conveyed on the top plate, and conveying the objects;

[0024] S4. During the conveying process, the object is transferred to the turning point, the first chain plate and the second chain plate rotate relative to each other, and the first ball moves on the magnet assembly. At the same time, the object and the top plate move on the ring under inertia, and the position of the top plate on the ring changes. At this time, the length of each second spring changes accordingly;

[0025] S5. After the article passes through the turning point, each second spring pulls the top plate to return the top plate on the ring to its original position until the article is transported to the destination.

[0026] The present invention has the following beneficial effects:

[0027] 1. The present invention, by respectively arranging a positioning assembly and a traction assembly on each first chain plate and a second chain plate, and by adsorbing a magnet plate at the bottom of the chassis onto an adsorption plate, and adsorbing a first ball on a connecting seat at the bottom of the chassis onto a magnet assembly, enables the pallet assembly to be installed on the conveyor belt. This makes it possible to install different numbers of pallet assemblies on the conveyor belt according to conveying requirements, and when a pallet assembly is damaged, it can also be easily replaced.

[0028] 2. In the present invention, the tray assembly is connected to the top of the first chain plate through the magnetic attraction of the magnet plate and the adsorption plate, and the magnet plate is limited by the limit plate, so that the tray assembly cannot rotate above the first chain plate. Therefore, when the tray assembly enters the turning point of the conveyor, the tray assembly will not move relative to the first chain plate. When the first chain plate and the second chain plate rotate relative to each other, since the other side of the bottom of the tray assembly is movably arranged above the second chain plate through the magnetic attraction of the magnet assembly and the first ball, when the first chain plate and the second chain plate rotate relative to each other, the first ball rolls on the magnet assembly to stably connect the tray assembly to the top of the second chain plate. After passing the turning point, the positions of the first chain plate and the second chain plate return to the original state, and the first ball will also roll back to the original position on the magnet assembly at the same time, so that the position of the tray assembly relative to the first chain plate and the second chain plate will not change, so that the items will not deviate from the original position after passing the turning point, so that the conveying accuracy of the conveyor will not be reduced.

[0029] 3. The present invention enables magnetic adsorption between the first ball and the magnet assembly, and connects the magnet assembly to the inner wall of the limiting groove through the first spring. The magnet assembly can slide in the limiting groove. When the tray assembly is transported to the bottom of the support, the first ball and the magnet assembly can always be kept in tight contact with each other through magnetic attraction, thereby avoiding intermittent separation of the tray assembly and the first ball during transportation, resulting in a collision between the tray assembly and the first ball, and preventing the tray assembly and the first ball from being damaged due to the collision, thereby affecting the operation of the device.

[0030] 4. In the present invention, when the articles pass through the turning, the articles drive the top plate to slide above the circular ring under the inertia state. During the sliding process, the pulling force of each second spring changes to different degrees, pulling the top plate so that the top plate will not deviate greatly from the circular ring. After the articles pass through the turning, each second spring respectively pulls and resets the top plate so that the top plate is in the original position relative to the circular ring, thereby preventing the articles from changing position relative to the tray assembly and the first chain plate and the second chain plate. After passing through the turning, the articles will not slide on the tray assembly due to inertia, thereby preventing the conveying accuracy of the conveyor from being reduced.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0047] See also Figure 1 - Fig.12As shown, a flexible curved conveyor comprises a machine base 1, a support 2 fixedly mounted above the machine base 1, a power assembly 3 fixedly mounted at one end of the support 2, and a conveyor belt 4 movably arranged inside the support 2, the power assembly 3 drives the conveyor belt 4, the conveyor belt 4 is composed of a plurality of movably connected chain plate groups 41, the chain plate group 41 is composed of two movably connected first chain plates 411 and second chain plates 412, a positioning assembly 5 is arranged above the first chain plate 411, a traction assembly 6 is arranged above the second chain plate 412, the positioning assembly 5 and the traction assembly 6 are alternately distributed on the conveyor belt 4, a plurality of tray assemblies 7 are arranged on the conveyor belt 4, each tray assembly 7 is connected to a chain plate group 41, a connecting assembly 8 is arranged at the bottom of the tray assembly 7, and the connecting assembly 8 is respectively connected to the positioning assembly 5 and the traction assembly 6;

[0048] The positioning assembly 5 includes an adsorption plate 51 and a plurality of limit plates 52 fixedly arranged above the first chain plate 411, and the adsorption plate 51 is located inside the plurality of limit plates 52;

[0049] A limiting groove 10 is provided above the second chain plate 412, and the traction assembly 6 includes a first spring 61 and a magnet assembly 62 arranged inside the limiting groove 10, and the magnet assembly 62 is connected to the inner wall of the limiting groove 10 through the first spring 61;

[0050] The tray assembly 7 includes a bottom plate 71, a circular ring 72 disposed on the upper edge of the bottom plate 71, a top plate 73 disposed above the circular ring 72, and a plurality of second springs 74 evenly spaced between the top plate 73 and the circular ring 72. The top plate 73 slides above the circular ring 72, one end of the second spring 74 is connected to the inner side wall of the top plate 73, and the other end of the second spring 74 is connected to the outer wall of the circular ring 72.

[0051] The connecting component 8 includes a magnet plate 81 fixedly arranged on one side of the bottom of the chassis 71, a connecting seat 82 fixedly arranged on the other side of the bottom of the chassis 71, and a first ball 83 rollingly arranged at the bottom of the connecting seat 82. A plurality of first balls 83 are arranged at the bottom of the connecting seat 82. The magnet plate 81 magnetically adsorbs the adsorption plate 51, and the magnet assembly 62 magnetically adsorbs the first ball 83.

[0052] During use of the device, the pallet assembly 7 is installed on the conveyor belt 4 by respectively providing a positioning assembly 5 and a traction assembly 6 on each of the first chain plate 411 and the second chain plate 412, and by adsorbing the magnet plate 81 at the bottom of the chassis 71 onto the adsorption plate 51, and adsorbing the first ball 83 on the connecting seat 82 at the bottom of the chassis 71 onto the magnet assembly 62. This makes it possible to install different numbers of pallet assemblies 7 on the conveyor belt 4 according to conveying requirements, and when a pallet assembly 7 is damaged, it can also be easily replaced.

[0053] When the flexible curved conveyor in the device is conveying articles, relative rotation occurs between the first chain plate 411 and the second chain plate 412 at the turning point of the conveyor.

[0054] In order to solve the problem that when an article passes through a turn in a flexible curved conveyor, the relative rotation between the first chain plate 411 and the second chain plate 412 causes the position of the article to change, causing the article to deviate from its original position when leaving the turn, resulting in low conveying accuracy of the conveyor, based on this device, a tray assembly 7 is arranged above the first chain plate 411 and the second chain plate 412. In the process of conveying articles, since the bottom side of the tray assembly 7 is connected to the first chain plate 411 through the magnetic attraction of the magnet plate 81 and the adsorption plate 51, and the magnet plate 81 is limited by the limit plate 52, the tray assembly 7 cannot rotate above the first chain plate 411. Therefore, when the tray assembly 7 enters the turn of the conveyor, the tray assembly 7 will not move relative to the first chain plate 411. When the first chain plate 411 and the second chain plate 412 rotate relative to each other, since the other side of the bottom of the tray assembly 7 is movably arranged above the second chain plate 412 through the magnetic attraction of the magnet assembly 62 and the first ball 83, when the first chain plate 411 and the second chain plate 412 rotate relative to each other, the tray assembly 7 is stably connected above the second chain plate 412 through the rolling of the first ball 83 on the magnet assembly 62. After passing the turning point, the positions of the first chain plate 411 and the second chain plate 412 return to their original states, and the first ball 83 also rolls back to its original position on the magnet assembly 62 at the same time, so that the position of the tray assembly 7 relative to the first chain plate 411 and the second chain plate 412 will not change, so that the items will not deviate from their original positions after passing the turning point, thereby ensuring that the conveying accuracy of the conveyor will not be reduced.

[0055] The first ball 83 and the magnet assembly 62 are in contact, and the wear problem of the device can be avoided when the first chain plate 411 and the second chain plate 412 rotate relative to each other. When the tray assembly 7 is transported to the bottom of the support 2, the tray assembly 7 vibrates due to the vibration of the first chain plate 411 and the second chain plate 412 during the transportation process, which easily causes the tray assembly 7 and the first ball 83 to collide. At this time, by making the first ball 83 and the magnet assembly 62 magnetically adsorbed, and the magnet assembly 62 connected to the inner wall of the limit groove 10 through the first spring 61, the magnet assembly 62 can slide in the limit groove 10, which can make the first ball 83 and the magnet assembly 62 always tightly contacted by magnetic attraction, avoiding the intermittent separation of the tray assembly 7 and the first ball 83 during the transportation process, resulting in the collision of the tray assembly 7 and the first ball 83, and preventing the tray assembly 7 and the first ball 83 from being damaged due to the collision, affecting the operation of the device.

[0056] In order to solve the problem that the objects are easy to slide on the first chain plate 411 and the second chain plate 412 due to inertia when passing through the turn in the flexible curved conveyor, causing the objects to deviate from the original position when leaving the turn, resulting in low conveying accuracy of the conveyor, the tray assembly 7 is optimized based on the present device. The tray assembly 7 is set as a connection structure of the bottom plate 71, the ring 72, the top plate 73, and the second spring 74. The ring 72 always remains stationary relative to the bottom plate 71, and there is a large friction between the objects and the top plate 73. This friction makes the objects always remain stationary relative to the top plate 73. When the items pass through the turning, the items drive the top plate 73 to slide above the ring 72 under inertia. During the sliding process, the pulling force of each second spring 74 changes to varying degrees, pulling the top plate 73 so that the top plate 73 does not deviate significantly from the ring 72. After the items pass through the turning, each second spring 74 respectively pulls and resets the top plate 73 so that the top plate 73 is in its original position relative to the ring 72. This prevents the items from changing position relative to the tray assembly 7, and prevents the items from changing position relative to the first chain plate 411 and the second chain plate 412. After passing through the turning, the items will not slide on the tray assembly 7 due to inertia, thereby preventing the conveying accuracy of the conveyor from being reduced.

[0057] There are gaps between the plurality of limit plates 52 , the contact surfaces of the magnet plate 81 and the adsorption plate 51 are of the same shape and size, the limit plates 52 and the side walls of the magnet plate 81 fit together, and a flexible spacer 11 is fixedly installed at the bottom of the magnet plate 81 .

[0058] Based on the present device, the spacing arrangement prevents the plurality of limit plates 52 from forming a closed space at the adsorption location of the magnet plate 81 and the adsorption plate 51, and a negative pressure environment is not formed when the magnet plate 81 is removed from the adsorption plate 51, thereby avoiding obstacles when removing the magnet plate 81. The arrangement of the flexible spacer 11 can prevent the magnetic material from being adsorbed on the bottom of the magnet plate 81, prevent the magnetic material from entering between the magnet plate 81 and the adsorption plate 51, and at the same time absorb energy between the magnet plate 81 and the adsorption plate 51, reduce the vibration of the adsorption plate 51 on the magnet plate 81, and avoid continuous vibration that reduces the magnetism of the magnet plate 81.

[0059] Among them, the magnet assembly 62 includes a base frame 621 movably arranged in the limiting groove 10, a magnet block 622, and a flexible partition 623 fixedly installed above the magnet block 622, two first springs 61 are arranged at the bottom of the base frame 621, one end of the first spring 61 is fixedly connected to the inner top wall of the base frame 621, and the other end of the first spring 61 is fixedly connected to the bottom wall of the limiting groove 10.

[0060] Based on the present device, the side wall of the limiting groove 10 is provided with a flexible layer, which plays a shock-absorbing role on the magnet block 622, and prevents continuous vibration from reducing the magnetism of the magnet block 622. The friction between the first ball 83 and the flexible interlayer 623 is large, so that the first ball 83 rolls on the flexible interlayer 623, which is convenient for the flexible interlayer 623 to clean the dirt on the surface of the first ball 83, and prevents dirt from entering the connecting seat 82, causing the first ball 83 to roll poorly in the connecting seat 82, causing the first ball 83 to slide on the magnet block 622, resulting in wear of the first ball 83 and the magnet block 622. The setting of the flexible interlayer 623 prevents the first ball 83 from directly contacting the magnet block 622, further avoiding the wear problem.

[0061] Among them, the tray assembly 7 also includes a connecting plate 75 and a movable seat 76 arranged at the bottom of the top plate 73, the movable seat 76 is located in the middle of the connecting plate 75, the bottom plate 71 is fixedly installed at the bottom of the connecting plate 75 by a first screw 12, and the movable seat 76 is fixedly installed at the bottom of the top plate 73 by a second screw 13. The ring 72 and the connecting plate 75 have the same height, the ring 72 is sleeved on the outside of the connecting plate 75, and the top plate 73 moves above the connecting plate 75. There is a movable circular cavity 14 between the bottom plate 71 and the connecting plate 75, the diameter of the movable circular cavity 14 is larger than the diameter of the movable seat 76, and the movable seat 76 moves inside the movable circular cavity 14.

[0062] Based on this design, the installation of the connecting plate 75 and the movable seat 76 allows the movable seat 76 to move inside the movable circular cavity 14, so that the top plate 73 only moves on the connecting plate 75, thereby improving the overall stability of the tray assembly 7 and increasing the service life of the tray assembly 7.

[0063] A plurality of second balls 15 are arranged to roll inside the movable seat 76 , and the plurality of second balls 15 are evenly spaced and distributed on the movable seat 76 . The second balls 15 in the movable circular cavity 14 do not contact the bottom plate 71 and the connecting plate 75 at the same time.

[0064] Based on this design, during the process of conveying items, the second ball 15 rolls on the bottom plate 71. The second ball 15 is arranged so that the top plate 73 and the connecting plate 75 do not contact each other, thereby avoiding friction therebetween. When the items pass through a turning point, it is convenient for the items to drive the top plate 73 to move synchronously, thereby avoiding relative movement between the items and the top plate 73. After passing through the turning point, it is convenient for the second spring 74 to reset the top plate 73 that has deviated from its original position.

[0065] Among them, a plurality of first hooks 16 are fixedly provided on the outer wall of the circular ring 72, and the first hooks 16 are evenly spaced on the outer wall of the circular ring 72; a plurality of second hooks 17 are fixedly provided on the inner wall of the top plate 73, and the second hooks 17 are evenly spaced on the inner wall of the top plate 73; the number of the first hooks 16, the second hooks 17 and the second springs 74 are the same and correspond one to one; one end of the second spring 74 is hung on the corresponding first hook 16, and the other end of the second spring 74 is hung on the corresponding second hook 17.

[0066] Based on the present design, the provision of the first hook 16 facilitates the connection of the second spring 74 on the ring 72 , and the provision of the second hook 17 facilitates the connection of the second spring 74 in the top plate 73 .

[0067] Among them, an anti-skid pad 9 is fixedly arranged above the top plate 73 .

[0068] Based on the present design, the provision of the anti-skid pad 9 increases the friction force on the object, making it more difficult for the object to move on the top plate 73.

[0069] The surface of the first rolling ball 83 is electroplated with a wear-resistant and rust-resistant coating.

[0070] Based on this design, it is convenient to protect the first rolling ball 83.

[0071] The first spring 61 and the second spring 74 are both in an extended state.

[0072] Based on this design, the restoring capabilities of the first spring 61 and the second spring 74 are improved.

[0073] A working method of a flexible curve conveyor comprises the following steps:

[0074] S1. When in use, multiple tray assemblies 7 are installed on the conveyor belt 4 according to the conveying requirements;

[0075] S2. During the installation process, the magnet plate 81 at the bottom of the chassis 71 is inserted into the plurality of adsorption plates 51 so that the magnet plate 81 is adsorbed on the adsorption plates 51, and the first ball 83 on the connecting seat 82 at the bottom of the chassis 71 is placed on the magnet assembly 62 so that the magnet assembly 62 and the first ball 83 are adsorbed;

[0076] S3, starting the power assembly 3, the power assembly 3 drives the conveyor belt 4, placing the objects to be conveyed on the top plate 73, and conveying the objects;

[0077] S4. During the conveying process, the object is transferred to the turning point, and the first chain plate 411 and the second chain plate 412 rotate relative to each other, and the first ball 83 moves on the magnet assembly 62. At the same time, the object and the top plate 73 move on the ring 72 under inertia, and the position of the top plate 73 on the ring 72 changes. At this time, the length of each second spring 74 changes accordingly;

[0078] S5. After the article passes through the turning point, each second spring 74 pulls the top plate 73 to return the top plate 73 on the ring 72 to its original position until the article is transported to the destination position.

[0079] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention.
