Description

Technical Field

[0001] The utility model belongs to the technical field of conveying systems, and in particular relates to a heavy-load cross conveying device and a multi-station automatic conveying system. Background Art

[0002] During the production process, products need to be transported between different workstations to complete the processing and assembly of equipment. Commonly used conveying equipment in factories include gantry trucks, forklifts and roller conveyors. Among them, roller conveyors are a very common item conveying equipment that can convey products that have completed the previous processing to the next process. Compared with other conveying methods, roller conveyors can convey products with larger weight and volume, and unlike forklifts and other equipment that require manual transportation one by one, they have higher conveying efficiency. However, roller conveyors can only be used for linear transportation, and usually roller conveyors need to be set up with the overall planning of the factory. For traditional roller conveyors, products must first be transported to the equipment at the end of the roller conveyor for processing. However, due to the limited space in the factory and the fact that roller conveyors can only be used for linear transportation, it is necessary to wait until this process is completed before the products to be processed can be transported to the location to start the next processing, which cannot effectively utilize the factory space and production time.

[0003] In the prior art, a rotating device is provided at the bottom of the roller to perform conveying direction reversal. When the product is conveyed to the set position, the roller stops conveying and turns under the control of the rotating device. Although this method can achieve conveying direction reversal, it requires rotating the roller at the end of the entire conveyor line and the product placed on the roller, which consumes a lot of energy and makes it difficult to transport heavy products.

[0004] In a Chinese invention patent with application number CN202011169818.8 and application date October 29, 2020, a reversing conveyor roller is disclosed, including a first roller system, a second roller system and a plurality of driving devices; the first roller system is located on the upper surface of a fixed bracket, and the plurality of driving devices are located below the fixed bracket; the first roller system and the second roller system are arranged crosswise, and the plurality of driving devices drive the first roller system and the second roller system respectively. The first roller system includes a plurality of first rollers arranged side by side, the second roller system includes a plurality of second rollers arranged side by side, and the plurality of first rollers and the plurality of second rollers are on the same height plane; the plurality of first rollers and the plurality of second rollers are arranged in an X shape and do not interfere with each other and the axes are perpendicular to each other, and the plurality of first rollers and the plurality of second rollers are in a rotationally symmetrical structure, and the change of the product conveying direction can be completed by adjusting the conveying direction of the first roller system and the second roller system. Although the reversing conveyor roller does not need to rotate, during the conveying process, since the first roller system and the second roller system are at the same height, when the conveying direction is adjusted, some non-working rollers will be worn, causing damage to the rollers. It is still not suitable for the reversing conveying of heavy products. Summary of the invention

[0005] The utility model provides a heavy-load cross conveying device to solve the technical problems in the prior art, such as the difficulty in reversing the conveying of heavy products, the inability to effectively utilize factory space, and the low production efficiency. The utility model also provides a multi-station automatic conveying system to solve the above technical problems.

[0006] The utility model provides a heavy load cross conveying device, the technical solution is:

[0007] The heavy-load cross-conveyor device is used to be installed on the turning position of the main conveyor line. The heavy-load cross-conveyor device includes at least one rotating conveying mechanism, which is driven to rise and fall by the jacking system. When the rotating conveying mechanism is raised, the top height is higher than or equal to the branch conveyor line, and when the jacking steering mechanism is lowered, the top is lower than the main conveyor line; the conveying direction of the rotating conveying mechanism is consistent with the conveying direction of the branch conveyor line. The rotating conveying mechanism is driven by a rotating conveying drive device, and the rotating conveying mechanism can rotate forward and reverse; the jacking system includes a jacking drive device, a lifting mechanism and a connecting shaft system. Each rotating conveying mechanism corresponds to a lifting mechanism. The lifting mechanism is connected to the jacking drive device through the connecting shaft system.

The branch drive shaft drives the lifting mechanism.

[0008] The beneficial effect is: the rotating conveying device is installed on the turning position of the main conveyor line. When the product that needs to enter the branch conveyor line reaches the turning position, the jacking system drives the rotating conveying mechanism to rise to the set height, and the product is transported to the branch conveyor line through the rotating conveying mechanism; if the product on the branch conveyor line needs to turn to enter the main conveyor line, when the product reaches the junction of the branch conveyor line and the main conveyor line, the rotating conveying mechanism is turned to the set height and reversed to transport the product from the branch conveyor line to the main conveyor line, and then the rotating conveying mechanism is withdrawn, and the product is transported by the main conveyor line, thereby realizing the turning of the product from the branch conveyor line to the main conveyor line, solving the problem of product reversal and transportation difficulties. In addition, it effectively solves the problem that the conveyor line can only carry out linear transportation and cannot effectively utilize the factory space, and can allocate the factory space more reasonably, which is conducive to improving the overall production efficiency. Moreover, when the product does not need to turn, the rotating conveying mechanism can be withdrawn below the main conveyor line to avoid wear of the rotating conveying mechanism and ensure the service life of the heavy-load cross conveying device. In addition, by setting up a connecting shaft system, the lifting and lowering of multiple rotating conveying mechanisms can be driven by one lifting drive device, reducing the number of required equipment and making the product structure more compact.

[0009] Furthermore, the rotating conveying mechanism is a translation chain, the lifting system is connected to the sprocket of the translation chain, and the rotating conveying driving device is a chain motor.

[0010] The beneficial effects are: the translation chain has a simple structure, is light in weight, and is easy to lift and retract.

[0011] Furthermore, a translation chain support member for supporting the translation chain is provided on the top of the sprocket and between the chain and the sprocket.

[0012] The beneficial effect is that by setting the translation chain support, the supporting capacity of the translation chain can be effectively improved, and it can support products of greater weight, and is further suitable for the transportation scenario of heavy products.

[0013] Furthermore, the bottom length of the translation chain support is shorter than the top, and the overall shape is an inverted isosceles trapezoid, the end face is a rectangle, the top is a support surface, the support surface is provided with a chain track, and the side is provided with bolt mounting holes.

[0014] The beneficial effect is that: a chain track is arranged on the supporting surface, so that the translation chain can move smoothly, and a bolt mounting hole is arranged on the side surface, and the chain is fixedly mounted by bolts.

[0015] Furthermore, the heavy-load cross-conveyor device includes four rotating conveying mechanisms, two of which form a group, and the rotating conveying mechanisms in each group are arranged in a row along the conveying direction of the main conveying line, and the two groups of rotating conveying mechanisms are arranged side by side perpendicular to the conveying direction of the main conveying line.

[0016] The beneficial effect is: setting up multiple rotating conveying mechanisms with higher supporting force can better support heavy products. In addition, the rotating conveying mechanisms are reasonably arranged to avoid product deflection during the turning transportation process, ensuring smooth transportation of the products.

[0017] The utility model provides a multi-station automatic conveying system, the technical solution is:

[0018] A multi-station automatic conveying system comprises a main conveyor line, a branch conveyor line is arranged on the side of the main conveyor line, the main conveyor line has a turning position, the branch conveyor line is arranged on the side close to the turning position of the main conveyor line, the transmission direction of the branch conveyor line forms a certain angle with the transmission direction of the main conveyor line, the speed, start and stop, forward and reverse rotation of the main conveyor line and the branch conveyor line are controlled by a controller, and a heavy-load cross-conveyor device is also arranged on the main conveyor line, and the heavy-load cross-conveyor device is the above-mentioned heavy-load cross-conveyor device.

[0019] The beneficial effect is: the rotating conveying device is installed on the turning position of the main conveyor line. When the product that needs to enter the branch conveyor line reaches the turning position, the jacking system drives the rotating conveying mechanism to rise to the set height, and the product is transported to the branch conveyor line through the rotating conveying mechanism; if the product on the branch conveyor line needs to turn to enter the main conveyor line, when the product reaches the junction of the branch conveyor line and the main conveyor line, the rotating conveying mechanism is first raised to the set height, the branch conveyor line continues to convey and the rotating conveying mechanism is reversed, and the product is transported from the branch conveyor line to the main conveyor line. After that, the rotating conveying mechanism stops and withdraws, and the product is transported by the main conveyor line, realizing the turning of the product from the branch conveyor line to the main conveyor line, solving the problem of difficulty in product reversal. In addition, it effectively solves the problem that the conveyor line can only carry out linear transportation and cannot effectively utilize the plant space, and can allocate the plant space more reasonably, which helps to improve the overall production efficiency. In addition, when the product does not need to turn, the rotating conveying mechanism can be withdrawn below the main conveyor line to avoid wear of the rotating conveying mechanism and ensure the service life of the heavy-load cross conveying device.

[0020] Furthermore, a stopper is provided on the main conveyor line, and the stopper is arranged at the turning position. The stopper includes a rocker arm, and the rocker arm has a fixed end, a free end and a buffer end. The fixed end is hinged on the fixed part, and the buffer end of the rocker arm is higher than the main conveyor line when raised, and lower than the main conveyor line when retracted; the free end is connected to a rocker arm driving member, and the free end and the fixed end are both located below the main conveyor line.

[0021] The beneficial effects are: the rocker structure is simple and easy to control, which can ensure the movement of the buffer end from above to below the main conveyor line.

[0022] Furthermore, both the main conveyor line and the branch conveyor line are roller system conveyor lines.

The rotating conveying mechanism of the heavy-load cross conveying device rises from the bottom of the main conveyor line through the roller interval to the set position, and the free end is raised to the top of the main conveyor line by the roller interval. The free end first passes through the first bent rod section and then through the straight rod section to connect to the fixed end, and the buffer end passes through the second bent rod section and is connected to the straight rod section.

[0023] The beneficial effects are: the overall structure of the roller conveyor line is simple, and heavy products can be transported. By arranging the first curved rod section and the second curved rod section, the roller structure can be avoided so that the free end passes through the gap between the rollers.

[0024] Furthermore, a rotating wheel is provided at the buffer end, and the rotating axis direction of the rotating wheel is perpendicular to the conveying direction of the main conveying line.

[0025] The beneficial effect is that when the product needs to stop, the buffer end is raised above the main conveyor line, and the transported product is contacted with the rotating wheel by the end, and is buffered by the rotating wheel to avoid damage to the product and the stopper caused by impact.

[0039] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings.

[0040] A specific embodiment 1 of a multi-station automatic conveying system provided by the utility model:

[0041] The embodiment provides a multi-station automatic conveying system, including a main conveying line and a branch conveying line. The main conveying line has a turning position, and the branch conveying line is arranged near the side of the turning position on the main conveying line. The transmission direction of the branch conveying line forms a certain angle with the transmission direction of the main conveying line. Figure 1 As shown, each group of branch conveyor lines includes two branch conveyor lines. The two branch conveyor lines in the same group are symmetrically arranged on the left and right sides of the main conveyor line, and the transmission direction of the branch conveyor line is perpendicular to the transmission direction of the main conveyor line. Correspondingly, the turning position in this embodiment is a square, and branch conveyor lines are provided on both sides. In this embodiment, the transmission direction of the main conveyor line during forward rotation is forward. The speed, start and stop, forward rotation and reverse rotation of the main conveyor line and the branch conveyor line are controlled by a controller. In this embodiment, the branch conveyor line and the main conveyor line are both roller system conveyor lines, and there is a fixed roller interval between the rollers of the roller system conveyor line.

[0042] like Figure 2 , Figure 5As shown, the multi-station automatic conveying system also includes a heavy-load cross-conveyor device, which includes at least one rotating conveying mechanism. The rotating conveying mechanism is driven to rise and fall by a lifting system. When the rotating conveying mechanism is raised, the top height is higher than or equal to the branch conveyor line. When the lifting and steering mechanism is lowered, the top is lower than the main conveyor line. The conveying direction of the rotating conveying mechanism is consistent with the conveying direction of the branch conveyor line. The rotating conveying mechanism is driven by a rotating conveying drive device, and the rotating conveying mechanism can rotate forward and reverse. In this embodiment, the rotating conveying mechanism is raised from the bottom of the main conveyor line through the roller interval to the set position. The rotating conveying mechanism is a translation chain; and the rotating conveying drive device is a chain motor. At the top of the sprocket of the translation chain, a translation chain support is also provided. The translation chain support is used to support the translation chain. When heavy products are moved by the translation chain, the translation chain can be effectively prevented from being crushed, thereby ensuring the stable operation of the heavy-load cross-conveyor device. Figure 7 The bottom length of the translation chain support is shorter than the top, and the whole is an inverted isosceles trapezoid. The end face of the translation chain support is a rectangle, and the top is a support surface. A chain track is provided on the support surface so that the translation chain can move smoothly. Bolt mounting holes are provided on the side, and the translation chain support is fixed and installed by bolts. In this embodiment, the translation chain support is a sheet metal part, which is integrally formed by mechanical processing and has good bearing capacity.

[0043] like Figure 3 The jacking system includes a jacking drive device, a lifting mechanism and a connecting shaft system. Each rotating conveying mechanism corresponds to a lifting mechanism. The lifting mechanism is connected to the jacking drive device through a connecting shaft system. The connecting shaft system includes a main drive shaft directly connected to the jacking drive device and a branch drive shaft driven by the main drive shaft. The branch drive shaft drives the lifting mechanism. The lifting mechanism is a jacking motor, and the jacking motor can rotate forward or reverse.

[0044] like Figure 4 , Figure 5 As shown, a stopper is also provided on the main conveyor line. In this embodiment, the stopper is arranged at the turning position. The stopper comprises a rocker, which has a fixed end, a free end and a buffer end. The fixed end is hinged on the fixed part. The buffer end of the rocker is higher than the main conveyor line when it is raised and lower than the main conveyor line when it is retracted. The free end of the rocker is connected to a rocker driving member. Both the free end and the fixed end are located below the main conveyor line. The free end rises from the roller interval of the roller conveyor line to above the main conveyor line. The free end first passes through the first curved rod section and then passes through the straight rod section to connect the fixed end. The buffer end passes through the second curved rod section and is connected to the straight rod section. The rocker driving member is a rocker cylinder. The rocker cylinder is controlled by a controller to control the stopper to move in the roller interval and above the main conveyor line. The curvature of the first curved rod section and the second curved rod section is used to avoid the rollers on both sides of the stopper, so as to ensure that the stopper can be raised from the roller interval. In this embodiment, a rotating wheel is provided at the buffer end, and the rotating axis direction of the rotating wheel is perpendicular to the conveying direction of the main conveyor line.

[0045] like Figure 1 As shown, a sensor is provided at the turning position, and the sensor is used to transmit the detected product position signal to the controller. The controller controls the conveying speed and forward and reverse rotation of the main conveyor line and the branch conveyor line according to the received product position signal, controls the lifting and retraction of the jacking and steering device, the forward and reverse rotation and speed of the translation chain, and controls the lifting and retraction of the stopper. In this embodiment, three sensors are provided at each turning position, two of which are arranged at the left and right sides of the turning position, namely the first sensor and the second sensor, and the other is arranged at the front side of the turning position, namely the third sensor. In this embodiment, when the first sensor and the second sensor detect the product position signal, the main conveyor line is controlled to gradually slow down the conveying speed, and when the third sensor detects that the product has reached the appropriate position, the main conveyor line is controlled to stop. In other embodiments, the main conveyor line can also be controlled to stop transportation according to the product position signal detected by the first sensor and the second sensor.

[0046] When the conveyed product needs to change direction, the first and second sensors will transmit the signal that the product has been conveyed to the set position to the controller, control the main conveyor line to slow down and start the rocker cylinder, and block the conveyed product through the stopper to prevent the product from moving forward due to inertia. After the product stops stably, the jacking and steering device is controlled to rise, and the translation chain rotates to convey the product to the branch conveyor line on one side of the preparation direction. Then the branch conveyor line on this side is controlled to start to complete the product reversal.

[0047] In this embodiment, the main conveyor line and the branch conveyor line are both driven by roller motors, and the roller motors are arranged below the rollers of the main conveyor line and the branch conveyor line.

[0048] In this embodiment, the lifting mechanism is a screw-nut mechanism, each rotating conveying mechanism corresponds to a screw-nut mechanism, the screw-nut mechanism is connected to the lifting motor through a connecting shaft system, the conveying direction of the translation chain is perpendicular to the direction of the main conveying line, and correspondingly, the branch conveying line and the main conveying line are arranged perpendicular to each other. Figure 1As shown, the heavy-load cross-conveyor device includes four rotating conveying mechanisms, each two in a group, and the rotating conveying mechanisms in each group are arranged in a row along the transmission direction of the main conveyor line. The two groups of rotating conveying mechanisms are arranged side by side perpendicular to the transmission direction of the main conveyor line. Each rotating conveying mechanism corresponds to a screw nut mechanism. In this embodiment, the connecting shaft system includes two main drive shafts and four branch drive shafts. The main drive shaft includes a first drive shaft and a second drive shaft. The branch drive shaft includes a third drive shaft, a fourth drive shaft, a fifth drive shaft and a sixth drive shaft. The first drive shaft and the second drive shaft are connected to the lifting motor through a coupling. The axial direction of the first drive shaft and the second drive shaft is perpendicular to the transmission direction of the main conveyor line. The first drive shaft is connected to the third drive shaft, and the third drive shaft drives the screw nut mechanism and is connected to the fourth drive shaft through a coupling. The fifth drive shaft drives the screw nut mechanism, the second drive shaft is connected to the fourth drive shaft, the fourth drive shaft drives the screw nut mechanism and is connected to the sixth drive shaft through a coupling, and the fifth drive shaft drives the screw nut mechanism.

[0049] like Figure 1 As shown, in this embodiment, the main conveyor line includes six conveyor sections, which are connected end to end along the conveying direction of the main conveyor line. The six conveyor sections are respectively conveyor section one, conveyor section two, conveyor section three, conveyor section four, conveyor section five and conveyor section six. All six conveyor lines are available. Two branch conveyor lines are symmetrically arranged at the ends of the six conveyor sections. Each branch conveyor line is numbered. Along the conveying direction of the main conveyor line, and starting from the right side, they are branch conveyor line one, branch conveyor line two, branch conveyor line three, branch conveyor line four, branch conveyor line five, branch conveyor line six, branch conveyor line seven, branch conveyor line eight, branch conveyor line nine, branch conveyor line ten, branch conveyor line eleven, and branch conveyor line twelve.

[0050] The specific working process is:

[0051] According to the different conveying position requirements of the products, taking the transportation of the products to the branch conveyor section as an example, the conveying process is as follows: the conveyor section starts, the product is conveyed to the turning position of the conveyor section, and the stopper on the conveyor section is opened. When the sensor on the conveyor section detects that the product is conveyed to the position, the conveyor section stops. After the product stops stably, the jacking and steering device rises, the translation chain starts and conveys it in the direction of the branch conveyor line. The branch conveyor line starts and transports the product to the branch conveyor line. After that, the translation chain stops, the jacking and steering device retreats, and the product is conveyed to the position by the branch conveyor line.

[0052] If the product is transported to the branch two conveyor line, after the jacking and steering device is raised, the translation chain will transport the product in the direction of the branch two conveyor line.

[0053] If the product is transported to the No. 3 conveyor line at the end of the second conveyor section, the conveying process is as follows: the first conveyor section starts, and when the product approaches the second conveyor section, the second conveyor section starts. When the product completely enters the second conveyor section, the first conveyor section stops, and the stopper on the second conveyor section is opened. When the product is transported to the turning position on the second conveyor section, when the sensor on the second conveyor section detects that the product is transported to the position, the second conveyor section stops. After the product stops stably, the jacking and steering device rises, the translation chain starts and transports it to the direction of the branch three conveyor line, and the branch three conveyor line starts to transport the product to the branch three conveyor line. After that, the translation chain stops, the jacking and steering device retreats, and the branch three conveyor line transports the product to the position. The process of transporting products to the remaining branch conveyor lines can be achieved by controlling the six conveyor sections and the translation chains of the jacking and steering devices on each conveyor section.

[0054] In addition, the product can also be transported from the branch conveyor line to the main conveyor line. Taking the product from branch conveyor line one to conveyor section six as an example, branch conveyor line one reverses to transport the product toward the main conveyor line, the lifting and translation device of conveyor section one rises, and the translation chain reverses. When the product is transported to the turning position on conveyor section one, branch conveyor line one and translation chain stop, the lifting and conveying device retreats, and conveyor section one and conveyor section two start forward rotation. When the product is transported to conveyor section three, conveyor section two stops and conveyor section three starts, and then the product is transported to conveyor section six section by section.

[0056] The only difference between this embodiment and Embodiment 1 is that in this embodiment, on the main conveyor line, in addition to the turning position, at least one sensor is also provided at other positions. When there is more than one sensor at other positions, the sensors are arranged at equal intervals, and a stopper is provided in front of each sensor. When the product at the turning position in front turns, the sensor at the subsequent position detects and transmits the position signal of the subsequent product, controls the stopper to rise, blocks the subsequent product, and turns the product at the turning position without stopping the conveyance of the main conveyor line.

[0057] Specific embodiment 3 of the multi-station automatic conveying system provided by the utility model:

[0058] The only difference between this embodiment and embodiment 1 is that sensor three is not provided, and the main conveyor line is controlled by the controller to gradually decelerate until it stops and stops at the provided stopper, so that the product stops stably at the turning position.
