Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0038] See Figures 1-3 , a preferred embodiment of the present invention discloses a drum - type conveying device, including: a frame 100, a drum conveying assembly 200 and a drum power source.

[0039] The frame 100 is provided with a common access position 110, a common upper and lower line position 120 and an avoidance position 130 which are arranged in sequence along the length direction of the frame 100 and are interconnected.

[0040] The common entry and exit position 110 is used for the mold to enter or exit the frame 100 , that is, the mold is placed into the frame 100 from the placement point along the common entry and exit position 110 , or is placed into the placement point from the common entry and exit position 110 of the frame 100 .

[0041] The common upper and lower line position 120 is used for the mold to enter the machine tool or enter the frame 100 from the machine tool, that is, the mold is placed in the machine tool from the common upper and lower line position 120 to complete installation, or the mold is placed from the machine tool into the common upper and lower line position 120 of the frame 100 to complete disassembly.

[0042] The avoidance position 130 is used to accommodate one of the molds to avoid the other mold. Among the two molds, one mold (i.e. the mold to be installed) is waiting to be put on the line, and the other mold (i.e. the mold to be removed) is waiting to be taken off the line.

[0043] The roller conveying assembly 200 includes a plurality of unit bearing rollers 210 sequentially arranged along the length of the frame 100. Multiple or all of the unit bearing rollers 210 are linked and connected by a transmission chain or a transmission gear. In one embodiment, the end of each unit bearing roller 210 is connected with a sprocket, and the roller conveying assembly 200 further includes a chain, and multiple or all of the sprockets are wound together by the chain, so that multiple or all of the sprockets rotate synchronously, thereby making multiple or all of the unit bearing rollers 210 of the roller conveying assembly 200 roll synchronously. In other embodiments, the end of each unit bearing roller 210 is connected with a transmission gear, and some or all of the adjacent two unit bearing rollers 210 are transmitted through the transmission gear, so that multiple or all of the unit bearing rollers 210 of the roller conveying assembly 200 roll synchronously.

[0044] The roller power source is connected to the roller conveying assembly 200 and is used to drive the unit bearing roller 210 to roll. The roller power source can drive all the unit bearing rollers 210 of the roller conveying assembly 200 to roll synchronously through the transmission mechanism, or the roller power source can sequentially drive the unit bearing rollers 210 of the common entry and exit position 110, the unit bearing rollers 210 of the common upper and lower line position 120, and the unit bearing rollers 210 of the avoidance position 130 through the transmission mechanism. It can be understood that when the unit bearing rollers 210 of the common entry and exit position 110, the unit bearing rollers 210 of the common upper and lower line position 120, and the unit bearing rollers 210 of the avoidance position 130 in the roller conveying assembly 200 are mutually transmission-connected, all the unit bearing rollers 210 of the roller conveying assembly 200 roll synchronously. When the unit bearing rollers 210 of the common entry and exit position 110, the unit bearing rollers 210 of the common upper and lower line position 120, and the unit bearing rollers 210 of the avoidance position 130 in the roller conveying assembly 200 are separated from each other, the unit bearing rollers 210 of the common entry and exit position 110, the unit bearing rollers 210 of the common upper and lower line position 120, and the unit bearing rollers 210 of the avoidance position 130 roll independently. Among them, the roller power source can be a total driving motor, in which case the unit bearing rollers 210 of the common entry and exit position 110, the unit bearing rollers 210 of the common upper and lower line position 120, and the unit bearing rollers 210 of the avoidance position 130 are driven by the same total driving motor; or it can be a plurality of independent unit motors, and the unit bearing rollers 210 of the common entry and exit position 110, the unit bearing rollers 210 of the common upper and lower line position 120, and the unit bearing rollers 210 of the avoidance position 130 are matched with a unit motor respectively.

[0045] In order to facilitate the transportation of the newly installed mold to the vicinity of the machine tool, in one embodiment, the frame 100 is provided with a plurality of wheels, so that the roller conveyor device of the utility model has its own mobile function, thereby reducing its length and reducing the distance requirement between the mold installation point and the machine tool.

[0046] During operation, the drum-type conveying device of the present utility model moves to the mold placement point, and then places the mold to be newly installed into the frame 100 from the common access position 110. Driven by the drum power source, the mold to be newly installed sequentially passes through the common access position 110, the common upper and lower line position 120, and the avoidance position 130, and stays at the avoidance position 130. It can be understood that during the process of the drum-type conveying device moving to the machine tool, the drum power source can synchronously and slowly send the mold to be newly installed into the avoidance position 130 to save working hours. When the drum-type conveying device arrives beside the machine tool, the mold to be disassembled is removed by the tooling of the machine tool and enters the frame 100 along the common upper and lower line position 120, and then enters the common access position 110 from the common upper and lower line position 120 driven by the drum power source. At this time, the common upper and lower line position 120 is already vacant, and the mold to be newly installed staying at the avoidance position 130 can enter the common upper and lower line position 120 driven by the drum power source, and then enter the machine tool from the common upper and lower line position 120. After completing the replacement of the mold, the drum-type conveying device moves to the mold placement point and places the mold to be disassembled into the mold placement point.

[0047] It can be understood that the mold changing sequence of the drum-type conveying device of the present utility model can be set according to requirements, that is, the mold to be disassembled can also be placed in the avoidance position 130 first, and the operation logic can be changed accordingly.

[0048] The drum-type conveying device provided by the present utility model is provided with a common access position 110, a common upper and lower line position 120, and an avoidance position 130 that are arranged in sequence along the length direction of the frame 100 and are interconnected. Thus, the avoidance position 130 can be used to avoid one of the molds, so that the other mold can be switched between the common upper and lower line position 120 and the machine tool. Therefore, after the frame 100 receives the mold to be disassembled, it can immediately send the mold to be newly installed into the machine tool, without waiting for the mold to be disassembled to be placed in the mold placement point before sending the mold to be newly installed into the machine tool, saving the time-consuming of the mold loading and unloading processes.

[0049] In one embodiment, in order to enable the drum-type conveying device to have the function of more easily transferring the mold to the machine tool, and to enable the drum-type conveying device to have the function of more easily transferring the mold of the machine tool to the frame 100, a mold lifter 300 is provided at the common upper and lower line position 120. The conveying direction of the mold lifter 300 is perpendicular to the conveying direction of the drum conveying assembly 200 in the horizontal plane. Among them, the mold lifter 300 is an existing mature product. Based on the drum conveying assembly 200 including a plurality of unit carrying drums 210 arranged in sequence along the length of the frame 100, the mold lifter 300 can be installed at the interval between adjacent unit carrying drums 210.

[0050] In one embodiment, in order to prevent the mold from accidentally slipping along the width direction of the machine frame 100, first anti - detachment guiding and limiting guardrails 140 are provided on both horizontal opposite sides of the shared access position 110.

[0051] Moreover, a second anti - detachment guiding and limiting guardrail 150 is provided on one side of the shared up - and - down line position 120. The horizontal side of the shared up - and - down line position 120 opposite to the second anti - detachment guiding and limiting guardrail 150 is the mold entrance / exit 152 of the shared up - and - down line position 120. A first lifting interception device 400 is provided at the mold entrance / exit 152. The first lifting interception device 400 is used to open or block the mold entrance / exit 152. When the mold entrance / exit 152 is open, the mold can be transported between the shared up - and - down line position 120 and the machine tool. When the mold entrance / exit 152 is closed, the first lifting interception device 400 prevents the mold from slipping from the mold entrance / exit 152 to the ground. Especially during the process of the roller - type conveying device walking between the mold placement point and the machine tool to transport the mold, the problem of the mold slipping sideways is more likely to occur. Among them, when the mold moves forward or backward in sequence between the shared access position 110, the shared up - and - down line position 120 and the avoidance position 130, the first lifting interception device 400 must block the mold entrance / exit 152 and guide the mold.

[0052] Similar to the first anti - detachment guiding and limiting guardrail 140, third anti - detachment guiding and limiting guardrails 160 are provided on both horizontal opposite sides of the avoidance position 130. A fourth anti - detachment limit is provided on the side of the avoidance position 130 far from the shared up - and - down line position 120, so that when the mold enters the avoidance position 130, it can be stably intercepted and will not fall to the ground.

[0053] In one embodiment, in order to prevent the mold from having a sliding friction phenomenon with the inner side wall of the first anti - detachment guiding and limiting guardrail 140, a plurality of first guiding wheels 141 are provided on the inner side wall of the first anti - detachment guiding and limiting guardrail 140 at intervals in sequence along the length direction of the first anti - detachment guiding and limiting guardrail 140. Based on the first guiding wheels 141 being pivotally connected to the machine frame 100, they can make rolling friction contact with the mold, so as to reduce the traveling resistance of the mold.

[0054] Similar to the first guiding wheels 141 being pivotally connected to the machine frame 100, a plurality of second guiding wheels 151 are provided on the inner side wall of the second anti - detachment guiding and limiting guardrail 150 at intervals in sequence along the length direction of the second anti - detachment guiding and limiting guardrail 150. Based on the second guiding wheels 151 being pivotally connected to the machine frame 100, they can make rolling friction contact with the mold, so as to reduce the traveling resistance of the mold.

[0055] It is pivotally connected to the first guide wheel 141 on the frame 100. A plurality of third guide wheels 161 are provided on the inner side wall of the third anti - detachment guide and limit guardrail 160 at intervals along the length direction of the third anti - detachment guide and limit guardrail 160. Based on the pivotal connection of the third guide wheel 161 to the frame 100, it can make rolling friction contact with the mold, thereby reducing the traveling resistance of the mold.

[0056] In one embodiment, the first lifting and intercepting device 400 includes a first vertical telescopic cylinder 410, a first guide sleeve 420 and a first rotating sleeve 430. The first output shaft of the first vertical telescopic cylinder 410 is movably inserted into the first guide sleeve 420. The first rotating sleeve 430 is movably sleeved on the first output shaft and is located above the first guide sleeve 420. The first rotating sleeve 430 is used for intercepting and guiding the mold. And, the bending strength of the first guide sleeve 420 is greater than that of the housing of the first vertical telescopic cylinder 410. It can be understood that a plurality of first lifting and intercepting devices 400 are provided on the frame 100, and the plurality of first lifting and intercepting devices 400 work synchronously and coordinately. During operation, when the first lifting and intercepting device 400 needs to block the mold entrance and exit 152, the first output shaft of the first vertical telescopic cylinder 410 extends upward, so that the first guide sleeve 420 blocks the mold entrance and exit 152. If the mold makes horizontal contact with the first guide sleeve 420 and applies a certain horizontal impact force to the first guide sleeve 420, since the first guide sleeve 420 is sleeved outside the first output shaft of the first vertical telescopic cylinder 410, and because the bending strength of the first guide sleeve 420 is relatively large, it can prevent the first output shaft of the first vertical telescopic cylinder 410 from bending. It should be noted that the housing of the first vertical telescopic cylinder 410 is generally made of aluminum alloy or pure aluminum, resulting in a relatively small bending strength, while the first guide sleeve 420 can be made of high - strength materials such as steel or alloy steel, and the thickness can be increased arbitrarily. In this way, by sleeving the first guide sleeve 420 outside the first output shaft of the first vertical telescopic cylinder 410, the horizontal impact resistance of the first output shaft of the first vertical telescopic cylinder 410 can be effectively improved.

[0057] In one embodiment, in order to accurately position the mold at the common access position 110, the common up - down line position 120 or the avoidance position 130, the frame 100 is provided with a second lifting and intercepting device 500 located between the common access position 110 and the common up - down line position 120. The second lifting and intercepting device 500 can rise or fall between the common access position 110 and the common up - down line position 120; and, the frame 100 is provided with a third lifting and intercepting device 600 located between the common up - down line position 120 and the avoidance position 130. The third lifting and intercepting device 600 can rise or fall between the common up - down line position 120 and the avoidance position 130.

[0058] With such a setting, when the mold needs to be accurately positioned at the common upper and lower line position 120, after the mold enters the common upper and lower line position 120 from the common access position 110, it is blocked by the third lifting interception device 600, and then the second lifting interception device 500 rises to form a closed-door posture. At this time, when the mold entrance and exit 152 is opened (that is, the first lifting interception device 400 is opened), the mold at the common upper and lower line position 120 can be sent into the machine tool. For example, the mold to be newly installed can be sent into the machine tool. In addition, when the mold needs to be accurately positioned at the avoidance position 130, after the mold enters the avoidance position 130 from the common upper and lower line position 120, it is blocked by the fourth anti-disengagement guiding and limiting guardrail 170, and then the third lifting interception device 600 rises to form a closed-door posture, so that the mold can be temporarily stopped at the avoidance position 130. For example, the mold to be newly installed passes through the common access position 110, the common upper and lower line position 120 or the avoidance position 130 in sequence and stays at the avoidance position 130.

[0059] It can be understood that a plurality of second lifting interception devices 500 are provided on the frame 100, and the plurality of second lifting interception devices 500 work synchronously and coordinately.

[0060] In addition, a plurality of third lifting interception devices 600 are provided on the frame 100, and the plurality of third lifting interception devices 600 work synchronously and coordinately.

[0061] In one embodiment, the structure of the second lifting interception device 500 is the same as the structure and working principle of the second lifting interception device 500 (for the sake of avoiding repetition, it can be understood by reference): The second lifting interception device 500 includes a second vertical telescopic cylinder, a second guide sleeve and a second rotating sleeve. The second output shaft of the second vertical telescopic cylinder is movably inserted into the second guide sleeve. The second rotating sleeve is movably sleeved on the second output shaft and is located above the second guide sleeve. The second rotating sleeve is used for intercepting and guiding the mold; the bending strength of the second guide sleeve is greater than the housing of the second vertical telescopic cylinder.

[0062] The structure of the third lifting interception device 600 is the same as the structure and working principle of the second lifting interception device 500 (for the sake of avoiding repetition, it can be understood by reference): The third lifting interception device 600 includes a third vertical telescopic cylinder, a third guide sleeve and a third rotating sleeve. The third output shaft of the third vertical telescopic cylinder is movably inserted into the third guide sleeve. The third rotating sleeve is movably sleeved on the third output shaft and is located above the third guide sleeve. The third rotating sleeve is used for intercepting and guiding the mold.

[0063] In other embodiments, the first lifting and intercepting device 400 can be a combination of an electric push rod and a lifting plate, and the electric push rod can be used to drive the lifting plate to move up and down. Similarly, the second lifting and intercepting device 500 can be a combination of an electric push rod and a lifting plate, and the electric push rod can be used to drive the lifting plate to move up and down. Similarly, the third lifting and intercepting device 600 can be a combination of an electric push rod and a lifting plate, and the electric push rod can be used to drive the lifting plate to move up and down.

[0064] In one embodiment, in order to prevent the mold from directly contacting the unit carrying roller 210 of the roller conveying assembly 200 and improve the smoothness of the mold operation, the frame 100 is equipped with a conveying plate 700, and the conveying plate 700 can move between the common access position 110, the common up and down line position 120 and the avoidance position 130.

[0065] In one embodiment, at least two sets of roller conveying assemblies 200 are provided. The two sets of roller conveying assemblies 200 are arranged at intervals in the width direction of the frame 100. The mold lifter 300 is located between the two sets of roller conveying assemblies 200. At least two sets of the roller conveying assemblies 200 are all connected to the roller power source. With this arrangement, only one roller power source can control the movement of the two sets of roller conveying assemblies 200, and they move synchronously to improve the accuracy of the mold walking. In addition, since at least two sets of roller conveying assemblies 200 are provided, more mold lifters 300 can be fully arranged on this basis, and the mold can be stably carried.
