Description

Technical Field

[0001] The invention relates to the technical field of coal packaging production, and in particular to a film roll transportation device. Background Art

[0002] FFS packaging machine, namely Form-Fill-Seal packaging machine, is a highly automated packaging equipment, mainly used for packaging powder, granular and flaky materials.

[0003] In the related art, the film changing operation of the film roll of the packaging machine is carried out by a forklift, a fork, and manual labor to take, transport, and load the film. The forklift driver operates the forklift, uses the fork to pick up the film roll, and delivers it to the film loading mechanism of the film roll of the packaging machine. The fork of the forklift is usually modified into a cylindrical shape, and the diameter of the modified fork is slightly smaller than the diameter of the core shaft of the film roll. The fork is inserted into the core shaft of the film roll and delivered to the film loading mechanism of the packaging machine.

[0004] However, due to the heavy weight of the film roll itself, the use of a forklift to pick up the film roll requires the cooperation of the operating vehicle and personnel, and the operation requirements are high. If the operation is not careful, it is easy to damage the core shaft of the film roll, making the entire roll unusable. In addition, the forklift delivers the film roll to the film loading mechanism, and the film roll needs to be unloaded by manpower, which is time-consuming and labor-intensive. Summary of the invention

DETAILED DESCRIPTION

[0025] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] The film roll transport device according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0027] like Figure 1 and Figure 2 As shown, the film roll transport device according to the embodiment of the present invention includes: a walking assembly, a supporting assembly and a control assembly.

[0028] The walking assembly has two supporting parts, which are spaced apart along a first direction. The two supporting parts define an assembly space 101 therebetween. The walking assembly can move along a second direction to place the film roll 100 to be replaced in the assembly space 101. The first direction and the second direction are perpendicular to each other.

[0029] The first direction refers to Figure 2 The left and right directions shown in , the second direction refers to Figure 2 The front-to-back direction shown in .

[0030] The support assembly includes two support members 21, and the two support members 21 correspond to the two support parts one by one. The support members 21 are installed on the corresponding support parts. The support members 21 can be raised and lowered in the vertical direction. A support shaft 22 is detachably provided between the two support members 21. The support shaft 22 is used to penetrate the core shaft cylinder of the film roll 100 in the assembly space 101 along the first direction.

[0031] The control component is arranged on the walking component, and the control component is connected to the two supporting members 21 to synchronously control the lifting and lowering of the two supporting members 21 .

[0032] It can be understood that, when working, the traveling assembly is moved in the front-back direction so that the film roll 100 is placed in the assembly space 101, and the position of the core barrel of the film roll 100 corresponds to the position of the support member 21. The height of the support member 21 is adjusted by the control assembly so that it corresponds to the height of the core barrel of the film roll 100, and then the support shaft 22 is inserted, and the support shaft 22 is respectively placed on the two support members 21. The height of the support member 21 is then adjusted by the control assembly so that the film roll 100 is lifted off the ground.

[0033] A single person pushes the walking assembly to the film loading mechanism of the FFS packaging machine, adjusts the height of the support member 21 through the control assembly, and puts down the film roll 100 to transport the film roll 100. After the transportation is completed, the operator takes out the support shaft 22 and replaces it with the shaft of the film loading mechanism of the FFS packaging machine to realize the film replacement operation.

[0034] In the forklift transportation method in the related art, due to the heavy weight of the film roll 100, careless operation can easily cause damage to the core barrel of the film roll 100. The film roll transportation device of the embodiment of the present invention avoids directly forking the film roll 100 by controlling the height and position of the support member 21, thereby reducing the risk of such damage.

[0035] The film replacement operation in the related art requires multiple cooperation between the forklift driver and the operator, and the operation is complicated. In the film roll transport device of the embodiment of the present invention, a single person can operate the walking assembly to complete the transportation of the film roll 100, without the need for multiple people to cooperate, thereby reducing the risk of human error that may occur during the operation. In addition, the operator does not need to manually push and unload the film roll 100, which reduces the labor intensity and operation time of the operator.

[0036] In some embodiments, Figure 1 and Figure 2 As shown, the traveling assembly includes a frame 11 and two bottom plates 12 , the bottom plates 12 are supporting parts, the frame 11 is arranged at the front end of the bottom plates 12 , and the control assembly is arranged on the frame 11 .

[0037] For example, the traveling assembly may be a hand-pushed forklift, which is modified to include a supporting assembly and a control assembly, thereby forming the film roll transport device according to the embodiment of the present invention.

[0038] It is understandable that a hand-push forklift is a common means of transportation, and modifying it on this basis can save the cost of purchasing a new device. In addition, the hand-push forklift has a simple structure and relatively low maintenance cost, and modifying it will not significantly increase the maintenance burden.

[0039] The hand-pushed forklift is easy to operate, and the modified film roll transport device of the embodiment of the present invention inherits this feature, so that the operator can quickly get started. The wheel design of the hand-pushed forklift makes it flexible to move in the workshop, and it is convenient to transport the film roll 100 between different work areas.

[0040] In some embodiments, Figure 1 and Figure 2 As shown, the walking assembly includes a direction wheel 13 and two moving wheels 14. The direction wheel 13 is arranged below the frame 11, and the two moving wheels 14 correspond to the two bottom plates 12 one by one. The moving wheels 14 are arranged on the corresponding bottom plates 12, and the moving wheels 14 are adjacent to the rear end of the bottom plates 12.

[0041] The direction wheel 13 is mainly responsible for controlling the direction of the walking assembly to ensure that the film roll 100 can move along a predetermined path during transportation. The direction wheel 13 is arranged below the frame 11, so that the stability of the frame 11 can be maintained and the operator can control the direction conveniently.

[0042] The moving wheels 14 are responsible for bearing the weight of the entire film roll transport device and moving along the ground under the guidance of the direction wheels 13. The moving wheels 14 correspond to the bottom plate 12 one by one and are located on the bottom plate 12, so that the weight can be dispersed and the pressure on the ground can be reduced.

[0043] The direction wheel 13 and the two moving wheels 14 together form a triangular support structure, which evenly distributes the weight, provides good stability, and prevents the transport device from tipping over during transportation.

[0044] In some embodiments, Figure 1 and Figure 2 As shown, a control handle 15 is provided on the steering wheel 13, and the height of the control handle 15 is adjustable.

[0045] It is understandable that the control handle 15 provides a human-machine interface, so that the operator can easily push or control the transport device, adjust the direction and move it. By adjusting the height of the control handle 15, the operating habits of operators of different heights can be adapted to improve the comfort and efficiency of operation.

[0046] Optionally, the control handle 15 can be raised and lowered by an internal retractable rod. Alternatively, the control handle 15 can use an adjustable connection (such as a knob, a bolt, etc.) to adjust the fixed height of the handle. Alternatively, the control handle 15 can use a pneumatic or hydraulic system to adjust the handle height, which usually needs to be used in conjunction with a solenoid valve and a control system.

[0047] In some embodiments, the support member 21 is a hydraulic cylinder.

[0048] It is understood that the hydraulic cylinder can provide greater force, suitable for heavy-loaded film rolls 100, and ensure stability and reliability during the lifting process. The control component can accurately control the extension and contraction of the hydraulic cylinder to achieve accurate lifting and lowering of the support member 21 to meet the needs of different heights. The hydraulic cylinder can provide smooth movement, reduce impact and vibration during the lifting process, and protect the film roll 100 from damage.

[0049] Furthermore, if Figure 1 and Figure 2 As shown, a mounting seat 23 is provided at the extended end of the piston rod of the support member 21 . The mounting seat 23 has a limiting groove 231 , and the support shaft 22 is fitted in the limiting groove 231 .

[0050] The mounting seat 23 provides a stable supporting platform for the support shaft 22. When used in conjunction with the limiting groove 231, the stability of the support shaft 22 can be increased to prevent the support shaft 22 from shaking or shifting during transportation. The limiting groove 231 allows the support shaft 22 to be quickly and accurately installed in place, thereby improving the efficiency of transportation. Similarly, the limiting groove 231 also makes the disassembly of the support shaft 22 simple and quick.

[0051] In some embodiments, Figure 1 and Figure 2 As shown, the control assembly includes an oil pump 31 , an oil tank 32 and an oil pipe 33 . The oil tank 32 is mounted on the vehicle frame 11 . The oil tank 32 is connected to the support member 21 through the oil pipe 33 . The oil pump 31 is arranged on the oil tank 32 .

[0052] The oil pump 31 is used as the power source of the hydraulic system. It compresses the hydraulic oil to provide pressure and drive the hydraulic cylinder to work. The oil tank 32 is used to store the hydraulic oil to ensure that the hydraulic system has sufficient oil supply. The oil pipe 33 is responsible for delivering the hydraulic oil output by the oil pump 31 to the hydraulic cylinder, and delivering the return oil of the hydraulic cylinder back to the oil tank 32.

[0053] The oil pump 31 is usually installed on the oil tank 32, so that the hydraulic oil can be directly drawn from the oil tank 32, simplifying the pipeline layout. The oil pump 31 can be a gear pump, a vane pump or a plunger pump.

[0054] It is understandable that integrating the oil pump 31, the oil tank 32 and the oil pipe 33 on the frame 11 can reduce the occupied space and improve the compactness of the overall design.

[0055] Alternatively, if Figure 1 and Figure 2 As shown, an oil filter 34 and a pressure gauge 35 are provided on the oil pipe 33. The main function of the oil filter 34 is to filter impurities and particles in the hydraulic oil, keep the hydraulic oil clean, and prevent these impurities from entering the hydraulic cylinder, thereby avoiding wear and blockage. The pressure gauge 35 is used to monitor the pressure in the hydraulic system to ensure that the system works within the correct pressure range.

[0056] Alternatively, if Figure 1 and Figure 2 As shown, an oil level gauge 36 is provided on the side wall of the oil tank 32. The oil level gauge 36 can display the liquid level of the hydraulic oil in the oil tank 32 in real time, so that the operator can intuitively understand the amount of oil. The oil level gauge 36 usually has high and low oil level marks, which can remind the operator whether the oil is within a safe range, thereby ensuring the safe operation of the system.

[0057] Furthermore, changes in the reading of the oil level gauge 36 can help to find leaks in the hydraulic system. If the oil level drops abnormally, it may indicate that there is a leak in the system.

[0058] In some embodiments, Figure 1 and Figure 2 As shown, the control assembly further includes a hydraulic control switch 37 . The hydraulic control switch 37 is disposed on the upper portion of the control handle 15 . The hydraulic control switch 37 is connected to the oil pump 31 .

[0059] It is understandable that the hydraulic control switch 37 is used to start and stop the operation of the oil pump 31 and control the pressure source of the hydraulic system. For example, the direction of the hydraulic oil flow can be changed by the hydraulic control switch 37, thereby controlling the action of the hydraulic cylinder.

[0060] The hydraulic control switch 37 is arranged on the upper part of the control handle 15, so that the operator can conveniently control the start and stop of the hydraulic system while operating the travel assembly. The position design of the control switch can reduce the operator's reaction time in an emergency, quickly perform an emergency stop operation, and improve the safety of the operator.
