Accumulation production line

Abstract

The accumulating assembly line of the present invention includes a substrate and a transfer assembly. The transfer assembly includes a drive unit, an annular belt, two rollers, at least one material blocking component, and at least one material carrying component. The two rollers are rotatably mounted on the substrate, and the annular belt is sleeved on the two rollers. The drive unit is mounted on the substrate, and the output shaft of the drive unit is connected to one of the rollers. Each material carrying component is slidably mounted on the substrate along the annular belt. Each material blocking component is mounted on the substrate and is adjacent to the annular belt. When the material blocking component pushes against the material carrying component, it separates the material carrying component from the annular belt, thereby making the material carrying component stationary relative to the substrate. When the material blocking component moves away from the material carrying component, it connects the material carrying component to the annular belt, thereby causing the annular belt to drive the material carrying component to slide relative to the substrate. In this way, the movement and stopping of the material carrying component can be controlled as needed, providing better flexibility and better compatibility with automated equipment at different workstations.

Description

Technical Field

[0001] This invention relates to the field of material conveying, and in particular to an accumulation-type conveyor line. Background Technology

[0002] Material handling refers to the spatial relocation of production materials. In industrial production, the most basic material handling process involves transferring products from different production workshops according to the production process flow. In the past, conveyor lines connected various production stations, with workers manually or using tools to complete localized processes on the products. The conveyor lines connected these processes to complete product production. Today, with the development of automation technology, each process is completed by automated equipment. Therefore, conveyor devices have evolved from belt conveyors to various structures such as chains and plate chains to meet the needs of transferring different products. This further reduces the number of workers, thereby improving production efficiency and quality.

[0003] There are two main types of conveying devices when transporting materials. The first type does not require fixtures. The materials are randomly placed on the conveying device for transport, and are located by means of photo recognition, etc., and then a robotic arm is driven to grab them. The second type is to install fixtures at equal intervals on the conveying device to fix the materials. The materials are placed in the fixtures in the same standard posture for equal-distance transport.

[0004] For the second type of conveying device mentioned above, each fixture needs to be installed at an equal distance. Therefore, during the design phase, it is necessary to set an appropriate number based on the number of product process steps, and at the same time, to set the distance between each production station so that when the conveying device drives each fixture to move, the fixture can accurately transfer each product to the corresponding station. Thus, when the product process is updated and the number of process steps changes, the original production equipment can no longer meet the production needs, requiring the design of a new generation of automated production equipment. This results in excessive repetition of equipment parts, leading to increased production costs. Therefore, given the poor flexibility and lack of sufficient compatibility of existing conveying devices, the fixtures on the conveying device cannot be installed or disassembled according to actual needs, and the fixed spacing between each fixture, the accumulating assembly line of this application is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an accumulation assembly line in which the fixtures can be installed or disassembled according to actual needs, and the spacing between the fixtures can be changed according to the requirements of the layout.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] An accumulation-type assembly line includes:

[0008] Substrate; and

[0009] A transfer assembly includes a drive unit, an annular belt, two rollers, at least one material blocking component, and at least one material carrying component. The two rollers are rotatably mounted on the substrate. The annular belt is sleeved on the two rollers. The drive unit is mounted on the substrate, and the output shaft of the drive unit is connected to one of the rollers. Each material carrying component is slidably mounted on the substrate along the annular belt. Each material blocking component is mounted on the substrate and is adjacent to the annular belt.

[0010] When the resisting element pushes against the carrier element, it separates the carrier element from the annular belt, thereby making the carrier element stationary relative to the substrate. When the resisting element moves away from the carrier element, it connects the carrier element to the annular belt, thereby causing the annular belt to drive the carrier element to slide relative to the substrate.

[0011] In one embodiment, the driving element is a motor.

[0012] In one embodiment, the cross-section of the annular belt is circular.

[0013] In one embodiment, the material blocking component includes two material blocking cylinders, both of which are disposed on the substrate and located on opposite sides of the annular belt. The output shaft of each material blocking cylinder is used to move closer to or further away from the material carrier.

[0014] In one embodiment, the resistive element further includes a sensor disposed on the substrate or the resistive element, and the orientation of the sensor is the same as the orientation of the output shaft of the resistive cylinder.

[0015] In one embodiment, the width of the annular belt is greater than the thickness of the wheel.

[0016] In one embodiment, the material carrier includes a material carrier plate, a pusher block, a return spring, and two clamping blocks. The material carrier plate is slidably disposed on the substrate, the pusher block is slidably disposed on the material carrier plate, the return spring abuts against the pusher block and the material carrier plate respectively, and the two clamping blocks are slidably disposed on the material carrier plate and connected to the pusher block. The two clamping blocks are located on both sides of the annular belt. The material blocking component is used to push the pusher block to slide relative to the material carrier plate so as to compress the return spring and cause the pusher block to drive the two clamping blocks away from the annular belt respectively.

[0017] In one embodiment, the carrier plate has a clearance groove, the annular belt is located in the clearance groove, and the two clamping blocks are located on both sides of the clearance groove.

[0018] In one embodiment, an annular groove is formed on the substrate, and the material carrier further includes a roller, which is rotatably disposed on the material carrier and housed within the annular groove.

[0019] In one embodiment, two annular grooves are provided, and the two annular grooves are respectively located on both sides of the substrate. Multiple rollers are provided, and each roller is divided into two groups. One group of rollers is located in one of the annular grooves, and the other group of rollers is located in the other annular groove.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] The accumulating production line of the present invention includes a substrate and a transfer assembly. The transfer assembly includes a drive member, an annular belt, two rollers, at least one material blocking member, and at least one material carrying member. The two rollers are rotatably mounted on the substrate, and the annular belt is sleeved on the two rollers. The drive member is mounted on the substrate, and the output shaft of the drive member is connected to one of the rollers. Each material carrying member is slidably mounted on the substrate along the annular belt. Each material blocking member is mounted on the substrate and is adjacent to the annular belt. When the material blocking member pushes against the material carrying member, it separates the material carrying member from the annular belt, thereby making the material carrying member stationary relative to the substrate. When the material blocking member moves away from the material carrying member, it connects the material carrying member to the annular belt, thereby causing the annular belt to drive the material carrying member to slide relative to the substrate. In this way, the material is carried by the material carrier, and the material can be accumulated and controlled. This makes the structure between the annular belt and each material carrier controllable and separable. Compared with the traditional fixed structure, the accumulation production line of this application can control the movement and stopping of the material carrier as needed, which is more flexible and has better compatibility with automated equipment at different workstations.

[0029] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention.

[0030] Please see Figure 1 An accumulation-type production line 10 includes a substrate 100 and a transfer assembly 200. The transfer assembly 200 includes a drive member 210, an annular belt 220, two rotating wheels 230, at least one material blocking member 240, and at least one material carrying member 250. Both rotating wheels 230 are rotatably mounted on the substrate 100. The annular belt 220 is sleeved on the two rotating wheels 230. The drive member 210 is mounted on the substrate 100, and its output shaft is connected to one of the rotating wheels 230. Each material carrying member 250 moves along the annular belt 220. The annular strip 220 is slidably disposed on the substrate 100. Each resisting element 240 is disposed on the substrate 100, and each resisting element 240 is disposed adjacent to the annular strip 220. When the resisting element 240 pushes against the carrier element 250, it separates the carrier element 250 from the annular strip 220, thereby making the carrier element 250 stationary relative to the substrate 100. When the resisting element 240 moves away from the carrier element 250, it connects the carrier element 250 with the annular strip 220, thereby making the annular strip 220 drive the carrier element 250 to slide relative to the substrate 100.

[0031] It should be noted that two rotating wheels 230 are rotatably mounted on the substrate 100 via bearings, and the two rotating wheels 230 are located at opposite ends of the substrate 100. An annular belt 220 is fitted onto the two rotating wheels 230, causing the two rotating wheels 230 to tension the annular belt 220. A drive member 210 is mounted on the substrate 100, and the output shaft of the drive member 210 is connected to one of the rotating wheels 230, enabling the drive member 210 to continuously rotate the annular belt 220. Each resisting element 240 is mounted on the substrate 100, and any two adjacent resisting elements 240 are not equidistant; that is, each resisting element 240 is arranged along the annular belt 220. The distance between each resisting element 240 can be set according to actual needs. Each carrying element 250 is slidably mounted on the substrate 100, and each carrying element 250 is also arranged along the annular belt 220, thereby enabling the annular belt 220 to drive each carrying element 250 to slide relative to the substrate 100. Specifically, when the resisting element 240 approaches the annular belt 220, causing it to push against the carrier element 250, the carrier element 250 separates from the annular belt 220. Therefore, the annular belt 220 continues to rotate, while the carrier element 250 is stopped and remains stationary relative to the substrate 100. It should be noted that subsequent carrier elements 250 following the stopped carrier element 250 will also be stopped sequentially upon contact with the stationary carrier elements 250 in front of them, thus all remaining stationary. Furthermore, when the resisting element 240 moves away from the carrier element 250, the carrier element 250 reconnects with the annular belt 220, allowing the annular belt 240 to move the carrier element 250 again. In this way, by having the carrier element 250 carry the material, material accumulation control is achieved, resulting in a controllable separation structure between the annular belt 220 and each carrier element 250. Therefore, when the accumulating assembly line 10 of this application is used in automated equipment, as the number of workstations increases, the quantity and position of the material blocking components 240 can be precisely controlled to stop the material carrier 250 at the corresponding position of each workstation simply by setting the quantity and position of the material blocking components 240 according to the number of workstations. Compared with the traditional fixed structure, the accumulating assembly line 10 of this application can control the movement and stopping of the material carrier 250 as needed, which is more flexible and has better compatibility with automated equipment at different workstations.

[0032] In one embodiment, the drive component 210 is a motor. The motor continuously drives the annular belt 220 to rotate, enabling the annular belt 220 to stably drive the movement of each material carrier 250. Furthermore, a reducer can be installed between the drive component 210 and the pulley 230, which can increase the output torque, thereby increasing the load capacity of the annular belt 220.

[0033] In one embodiment, the cross-section of the annular belt 220 is circular. Specifically, the annular belt 220 is set as a circular belt, so that an arc-shaped groove adapted to the circular belt can be correspondingly opened on the peripheral wall of the roller 230. In this way, when the annular belt 220 rotates continuously, there will be no positional misalignment between the annular belt 220 and the roller 230, thus ensuring the control accuracy of the accumulating assembly line 10.

[0034] In one embodiment, the material blocking member 240 is a single cylinder, which is mounted on the substrate 100. The drive shaft of the single cylinder can approach or move away from the annular belt 220. When it approaches the annular belt 220, the drive shaft can push the material carrier 250.

[0035] Please see Figure 1 In one embodiment, the material blocking component 240 includes two material blocking cylinders 241, both of which are disposed on the substrate 100 and are located on both sides of the annular belt 220. The output shaft of the material blocking cylinder 241 is used to move closer to or further away from the material carrier 250.

[0036] It should be noted that the two material-stopping cylinders 241 are respectively installed on both sides of the annular belt 241. The two material-stopping cylinders 241 operate synchronously, and their output shafts can extend or retract simultaneously. When the output shafts of the two material-stopping cylinders 241 extend simultaneously, they will push the material carrier 250 at the same time, thereby stopping the material carrier 250. In this way, setting the two material-stopping cylinders 241 to push the material carrier 250 simultaneously can ensure the stability of the material carrier 250.

[0037] Please see Figure 1 In one embodiment, the material blocking component 240 further includes a sensor 242, which is disposed on the substrate 100 or the material blocking component 242, and the orientation of the sensor 242 is the same as the orientation of the output shaft of the material blocking cylinder 241. It should be noted that the material carrier 250 is used to carry materials. When the material carrier 250 is successfully stopped, it needs to send a signal to the control system indicating that the material carrier 250 has reached its position. Therefore, the sensor 242 is mounted on the substrate 100, and the sensor 242 is oriented towards the annular belt 220. In one embodiment, the sensor 242 is a metal sensor, and the material carrier 250 is a metal structure.

[0038] Please see Figure 2In one embodiment, the width B of the annular belt 220 is greater than the thickness C of the rotating wheel 230. It should be noted that in order for the annular belt 220 to stably drive the material carrier 250 to slide, the material carrier 250 needs to clamp the annular belt 220. When the annular belt 220 drives the material carrier 250 past the rotating wheel 230, to avoid interference between the rotating wheel 230 and the material carrier 250, the width of the annular belt 220 is set to be greater than the thickness of the rotating wheel 230. This ensures that the material carrier 250 reliably clamps the annular belt 220.

[0039] Please see Figure 1 and Figure 3 In one embodiment, the material carrier 250 includes a material carrier plate 251, a pusher block 252, a return spring 253, and two clamping blocks 254. The material carrier plate 251 is slidably disposed on the substrate 100, the pusher block 252 is slidably disposed on the material carrier plate 251, the return spring 253 abuts against the pusher block 252 and the material carrier plate 251 respectively, and the two clamping blocks 254 are slidably disposed on the material carrier plate 251 and connected to the pusher block 252. The two clamping blocks 254 are located on both sides of the annular belt 220 respectively. The material blocking member 240 is used to push the pusher block 252 to slide relative to the material carrier plate 251 so that the return spring 253 is compressed and the pusher block 252 drives the two clamping blocks 254 away from the annular belt 220 respectively.

[0040] It should be noted that the material carrier plate 251 is slidably mounted on the base plate 100, the pusher block 252 is slidably mounted on the material carrier plate 251, and the return spring 253 pushes the pusher block 252 and the material carrier plate 251 respectively. The pusher block 252 is located in front of the material carrier plate 251 in the sliding direction. Thus, when the output shaft of the material blocking member 240 extends, it pushes the pusher block 252, thereby compressing the return spring 253 under the pushing force. Both clamping blocks 254 are slidably mounted on the material carrier plate 251, and both clamping blocks 254 are connected to the pusher block 252. Thus, when the pusher block 252 is pushed by the output shaft of the material blocking member 240, the pusher block 252 will drive the two clamping blocks 254 to slide away from the annular belt 220, thereby separating the material carrier 250 from the annular belt 220 and stopping the material carrier 250. When the output shaft of the material blocking component 240 retracts, the push block 252 resets under the elastic force of the return spring 253. Therefore, the push block 252 drives the two clamping blocks 254 to approach and abut against the annular belt 220, so that the two clamping blocks 254 together clamp the annular belt 220. In this way, the annular belt 220 can drive the material carrier 250 to return to its original position.

[0041] Please see Figure 3 In one embodiment, a relief groove 251a is provided on the material carrier plate 251, an annular belt 220 is located in the relief groove 251a, and two clamping blocks 254 are located on both sides of the relief groove 251a.

[0042] It should be noted that in order for the clamping blocks 254 to stably clamp the annular belt 220, a relief groove 251a is provided on the material carrier plate 251, so that the annular belt 220 is accommodated in the relief groove 251a, and the two clamping blocks 254 can clamp the two sides of the annular belt 220.

[0043] Please see Figure 1 and Figure 3 In one embodiment, an annular groove 110 is provided on the substrate 100, and the material carrier 250 further includes a roller 255, which is rotatably disposed on the material carrier plate 251 and is housed in the annular groove 110.

[0044] It should be noted that, in order to improve the sliding stability of the carrier plate 251, an annular groove 110 is formed on the substrate 100, and a roller 255 is installed on the carrier plate 251 so that the roller 255 rolls along the annular groove 110, and the carrier plate 251 can slide along the annular belt 220.

[0045] In one embodiment, two annular grooves 110 are provided, located on opposite sides of the substrate 100. Multiple rollers 255 are provided, each roller 255 divided into two groups. One group of rollers 255 is located within one annular groove 110, while the other group of rollers 255 is located within the other annular groove 110. This further improves the stability of the carrier plate 251 sliding relative to the substrate 100.

[0046] In one embodiment, two return springs 253 are provided, with the two return springs 253 located on both sides of the annular belt 220 respectively. It should be noted that by using the two return springs 253 to push the push block 252 simultaneously, it can be ensured that the push block 252 maintains force balance when sliding relative to the carrier plate 251.

[0047] Please see Figure 3 and Figure 4 In one embodiment, a limiting groove 251b is also provided on the material carrier plate 251, and at least a portion of the return spring 253 is accommodated in the limiting groove 251b. In this way, when the return spring 253 is compressed by force, it is limited by the inner sidewall of the limiting groove 251b, thus preventing the return spring 253 from falling off.

[0048] Please see Figure 3 and Figure 5 The push block 252 is provided with a limiting post 259, and the return spring 253 is at least partially sleeved on the limiting post 259. In this way, when the push block 252 is obstructed by the pushing force of the material 240, the limiting post 259 will be at least partially accommodated in the limiting groove 251b, which can improve the stability of the return spring 253 and prevent the return spring 253 from falling off.

[0049] Please see Figure 3 and Figure 4 In one embodiment, a sliding groove 251c is also provided on the material carrier plate 251. The sliding groove 251c is connected to the clearance groove 251a, and the two clamping blocks 254 are slidably disposed in the sliding groove 251c.

[0050] It should be noted that, in order to improve the lateral strength of the clamping block 254, a sliding groove 251c is provided, and the clamping block 254 is slidably mounted in the sliding groove 251c. Further, in one embodiment, the extension line of the extending direction of the sliding groove 251c is perpendicular to the extension line of the extending direction of the relief groove 251a. Thus, when the clamping block 254 slides out along the sliding groove 251c, the clamping block 254 clamps the annular belt 220 radially, thereby reliably fixing the material carrier 250 to the annular belt 220.

[0051] Please see Figure 1 and Figure 3 In one embodiment, the material carrier 250 further includes a carrier 256, which is detachably mounted on the material carrier plate 251. For example, the carrier 256 is fixed to the material carrier plate 251 by bolts, and the carrier 256 is used to carry materials.

[0052] Please see Figure 3 In one embodiment, the clamping block 254 has a plurality of protruding teeth 257 on one side of the side near the annular belt 220.

[0053] Thus, when each protruding tooth 257 abuts against the annular belt 220, it can increase the friction between the clamping block 254 and the annular belt 220, thereby improving the reliability of the connection between the material carrier 250 and the annular belt 220. In one embodiment, the protruding tooth 257 and the clamping block 254 are integrally formed.

[0054] Please see Figure 3 In one embodiment, the material carrier 250 further includes two clamping springs 258, one end of each clamping spring 258 abutting against the material carrier plate 251, and the other end of each clamping spring 258 abutting against two clamping blocks 254 respectively.

[0055] It should be noted that when the output shaft of the resisting component 240 retracts, the push block 252 resets under the elastic thrust of the return spring 253. At this time, to ensure that the two clamping blocks 254 reliably clamp the annular belt 220, a clamping spring 258 is provided on each of the two clamping blocks 254. Thus, the clamping springs 258 push the clamping blocks 254, ensuring that the two clamping blocks 254 reliably clamp the annular belt 220. It should be noted that the thrust direction of the clamping springs 258 is perpendicular to the thrust direction of the return spring 253.

[0056] Please see Figure 3 and Figure 5In one embodiment, a sloping push surface 252a is provided on each of the two sides of the push block 252, and a sloping top surface 254a is provided on each of the two clamping blocks 254. The two sloping push surfaces 252a abut against the two sloping top surfaces 254a respectively.

[0057] It should be noted that when the pusher block 252 is pushed and slid by the blocking member 240, since the inclined push surface 252a and the inclined top surface 254a are inclined at an angle, the pusher block 252 will generate a component force in the sliding direction of the clamping block 254, thereby causing the clamping block 254 to slide away from the annular belt 220. When the blocking member 240 moves away from the pusher block 252, the pusher block 252 is reset under the elastic pushing force of the return spring 253, causing the inclined push surface 252a to move away from the inclined top surface 254a, and then causing the clamping block 254 to clamp the annular belt 220 under the elastic pushing force of the clamping spring 258.

[0058] Please see Figure 6 In one embodiment, the length D of the inclined push surface 252a is less than the maximum sliding distance E of the push block 252 relative to the carrier plate 251.

[0059] It should be noted that in order to maintain the state in which the two clamping blocks 254 slide away from the annular belt 220, the length D of the inclined pushing surface 252a is set to be less than the maximum sliding distance E of the push block 252 relative to the carrier plate 251. When the push block 252 is pushed and slid to the limit position by the blocking component 240, the inclined pushing surface 252a will separate from the inclined top surface 254a. Therefore, no component force will be generated between the push block 252 and the clamping block 254, so the clamping block 254 cannot slide, thereby maintaining the state in which the clamping block 254 is away from the annular belt 220.

[0060] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
