Description

Technical Field

[0001] The present invention relates to an elevator, in particular to a cloth roll elevator. Background Art

[0002] The fabric is wound onto a take-up device, forming a roll. Once the roll is finished, the take-up shaft is removed from the roll and the roll is packaged. Because the rolls are long and heavy, they are typically transported to the truck bed using a hoist, saving labor.

[0003] Figure 1 This is an existing fabric roll elevator, consisting of an equipment frame, a scale, and multiple chain modules. The bottom of the equipment frame features a set of supporting casters for moving the elevator. The equipment frame is arranged horizontally in the following order: a weighing area, a placement area, a lifting area, and a drop area. The scale is located in the weighing area, and its platform is rectangular to accommodate the fabric rolls. Multiple chain modules are located in the drop area. The chains are fixedly connected to support bars, which move between two positions: a loading position below the placement area and a drop position corresponding to the intersection of the lifting and drop areas. First, the fabric roll is manually lifted and placed on the weighing platform, where its weight is measured and recorded. Next, a manual push is performed, causing the roll to roll from the weighing platform to the placement area. Finally, a manual start is performed, activating the multiple chain modules in sync, moving the support bars from the loading position to the drop position. During this process, multiple support bars press against the fabric roll, lifting it to the drop area, where it falls under its own weight.

[0004] Figure 1 Other issues with this type of elevator include: Because the fabric rolls are long and heavy, manually lifting the rolls and placing them on the weighing platform typically requires two people, each lifting one end of the roll. Furthermore, while the height of the rolls doesn't rise very high, repeated, long-term operations can still be laborious for operators. Summary of the Invention

[0005] The present application provides a cloth roll elevator, which can solve the problem that the existing cloth roll elevator needs to be operated by two people because the cloth needs to be lifted and placed on a weighing platform, and the operator has to operate it for a long time and multiple times, which is very laborious.

[0006] In this application, a cloth roll elevator is provided, comprising: The equipment frame has a set of supporting casters on the bottom; in the horizontal direction, there are weighing area, placement area, lifting area and unloading area; Scales, set up in the weighing area; Multiple chain modules are set in the lifting area; the chains are fixedly connected to support bars, which move between the following two positions: a loading position below the placement area and a unloading position corresponding to the intersection of the lifting area and the unloading area; Two sets of loading components are respectively arranged on both sides of the equipment frame; The loading assembly includes: a fork, a slider, an L-shaped rod and a connecting rod forming a parallelogram frame; the slider is connected to the equipment frame by sliding up and down; the L-shaped rod is hinged to the slider at the junction, and the first end is hinged to the fork; the connecting rod is hinged to the slider at the first end, and the second end is hinged to the fork; The drive assembly includes: a connecting portion and a linear mechanism; the connecting portion is laterally slidably connected to the bottom surface of the equipment frame, and is hinged on both sides of the longitudinal direction to the second ends of the two L-shaped rods; the linear mechanism is used to drive the connecting portion to move between a first position and a second position, wherein the first position causes the fork to be lower than the lower limit of the slider, and the second position causes the fork to be higher than the slider and connected to the upper limit of the scale.

[0007] In some embodiments, the fork has a transverse horizontal groove rail; the loading assembly further includes: a triangular plate, an L-shaped groove rail; the L-shaped groove rail is fixedly connected to a longitudinal side of the equipment frame; the first angle of the triangular plate and the L-shaped groove rail form a first groove pin pair, the second angle and the vertical section of the L-shaped groove rail form a second groove pin pair, and the third angle and the horizontal groove rail form a third groove pin pair.

[0008] In some embodiments, the triangular plate corresponds to an obtuse triangle, and the second angle corresponds to an obtuse angle.

[0009] In some embodiments, the top surface of the slider has a blocking rod, which is located on a side of the scale away from the fork in the horizontal direction; when the connecting portion is in the second position, the blocking rod extends beyond the scale.

[0010] In some embodiments, the method further includes: a placement plate fixedly connected between the two forks.

[0011] In some embodiments, the linear mechanism is a hydraulic cylinder.

[0012] In some embodiments, the piston rod of the hydraulic cylinder has a threaded section, and the connecting portion has a through hole for the threaded section to pass through; the threaded section is threadedly connected to nuts on both sides of the connecting portion.

[0013] In summary, in the present application, a cloth roll elevator is provided, which is equipped with two sets of feeding components and a driving component that synchronously drives the two sets of feeding components to move. The feeding components include: a fork, a slider, an L-shaped rod and a connecting rod. The movement of the connecting part relative to the equipment frame will simultaneously drive the following two movements: Movement one, the slider moves up and down relative to the equipment frame; Movement two, the L-shaped rod swings relative to the slider, thereby driving the fork to move relative to the slider. By swinging the fork relative to the slider, the up and down movement range of the fork is further expanded on the basis of the up and down movement range of the slider, meeting the feeding needs of the cloth roll rolling from the ground into the fork and the unloading needs of the cloth roll rolling from the fork into the weighing platform. Compared with the existing cloth roll elevator, it has the following beneficial effects: because there is no need to lift the cloth roll, only pushing the cloth roll to roll can make the cloth roll from the ground to the fork and from the fork to the weighing platform, so one person can complete the operation, and it is also easier for the operator to operate for a long time and multiple times.

Specific embodiments

[0017] The following is further explained with reference to the accompanying drawings, which are provided for illustrative purposes only and are not drawn to scale. Unless otherwise defined, technical or scientific terms used in this disclosure should have the same ordinary meaning as those understood by persons of ordinary skill in the art to which this disclosure pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; if the absolute position of the described object changes, the relative positional relationship may also change accordingly. The embodiments of this application are combinable unless there is a conflict.

[0018] See also Figure 1 and Figure 2 A cloth roll elevator includes: an equipment frame 1, a scale 2, multiple groups of chain modules 3, two groups of feeding components 4 and a driving component 5.

[0019] The equipment frame 1 can be constructed from welded square tubes, with a set of supporting casters 1a on its bottom. These casters 1a can be two fixed wheels with foot brakes and two universal wheels for moving the hoist. The equipment frame 1 is arranged horizontally into a weighing area 1b, a placement area 1c, a lifting area 1d, and a material placement area 1e.

[0020] The scale 2 is arranged in the weighing area 1b. In order to adapt to the cloth roll, the weighing platform 2a of the scale 2 is rectangular. The scale 2 is used to weigh the cloth roll before lifting.

[0021] After the cloth roll is weighed, it is manually pushed to roll down to the placement area 1c. Accordingly, the height of the placement area 1c is slightly lower than the weighing platform 2a of the scale 2, making it convenient to receive the cloth roll.

[0022] Multiple chain modules 3 are located in the lifting area 1d. More specifically, each chain module 3 may include a mounting portion, two sprockets rotating at either end of the mounting portion, and a chain tensioned between the two sprockets. The mounting portion may be welded to the placement area 1c and the blanking area 1e of the equipment frame 1, respectively. The sprockets at the same end of the multiple chain modules 3 may be connected by a single shaft, which can be driven by a motor to rotate, thereby driving the synchronous movement of all chains.

[0023] The chain of chain module 3 is fixedly connected to a support bar 3a. More specifically, one end of support bar 3a can be fixedly connected to one of the chain links via a pin. The other end of support bar 3a can be hooked. The movement of the chain causes support bar 3a to move between two positions: a loading position below placement area 1c (accordingly, placement area 1c can be composed of multiple side-by-side square tubes, with support bar 3a positioned between adjacent two square tubes) and a unloading position at the junction of lifting area 1d and blanking area 1e.

[0024] After the cloth roll rolls down from the weighing platform 2a to the placement area 1c, multiple sets of chain modules 3 are manually started, and the support bar 3a moves from the loading position to the unloading position to lift the cloth roll in the placement area 1c.

[0025] The blanking area 1e is inclined, the support bar 3a moves to the blanking position, and the cloth roll falls from the blanking area 1e under its own gravity.

[0026] See also Figure 2 and Figure 3 The two groups of loading components 4 are respectively arranged on both sides of the longitudinal direction of the equipment frame 1. The loading components 4 include: a fork 41, a slider 42, an L-shaped rod 43 and a connecting rod 44.

[0027] The slider 42 is connected to the equipment rack 1 for sliding up and down. More specifically, a first linear rail 42 b may be provided between the slider 42 and the equipment rack 1 .

[0028] The L-shaped rod 43 is hinged to the slider 42 at its junction, and the first end is hinged to the fork 41 .

[0029] See also Figure 2 and Figure 5The first end of the connecting rod 44 is hinged to the slider 42, and the second end is hinged to the fork 41. The fork 41, slider 42, L-shaped rod 43, and connecting rod 44 form a parallelogram. The two hinged locations of the slider 42 form a first line segment 42a, and the two hinged locations of the fork 41 form a second line segment 41a. Both the first line segment 42a and the second line segment 41a are horizontal and of equal length. During the fork 41's swing, it remains horizontal.

[0030] See also Figure 7 and Figure 8 The driving assembly 5 includes: a connecting part 51 and a linear mechanism 52.

[0031] The connecting portion 51 is connected to the bottom surface of the equipment rack 1 in a transverse sliding manner. More specifically, a second linear rail 51 a may be provided between the connecting portion 51 and the equipment rack 1 .

[0032] See also Figure 3 、 Figure 4 and Figure 5 The longitudinal sides of the connecting portion 51 are hinged to the second ends of the two L-shaped rods 43, respectively. This allows the two sets of loading assemblies 4 to move synchronously via the connecting portion 51. Accordingly, movement of the connecting portion 51 relative to the equipment frame 1 simultaneously drives the following two movements: Movement 1: the vertical movement of the slider 42 relative to the equipment frame 1; Movement 2: the swinging of the L-shaped rod 43 relative to the slider 42, thereby driving the movement of the fork 41 relative to the slider 42.

[0033] Combining the two aforementioned motions, the linear mechanism 52 drives the connecting portion 51 between a first position and a second position. The first position places the fork 41 below the lower limit of the slider 42, while the second position places the fork 41 above the slider 42 and connected to the upper limit of the scale 2. The fork 41 can be connected to the scale 2 in such a way that it can be flush with, slightly above, or slightly below the weighing platform 2a, allowing the fabric roll to roll from the fork 41 onto the weighing platform 2a.

[0034] It can be seen that when the connecting portion 51 moves between the first position and the second position and the fork 41 swings, the L-shaped rod 43 and the connecting rod 44 may overlap, and the fork 41 also needs to pass through the slider 42 .

[0035] See also Figure 5 and Figure 9The hinge point between the L-shaped rod 43 and the slider 42 can be on the longitudinal outer side of the slider 42, while the hinge point between the connecting rod 44 and the slider 42 can be on the longitudinal inner side of the slider 42. The L-shaped rod 43 and the connecting rod 44 are staggered so that they can overlap without interference. A third line segment 43a is formed by connecting the hinge points between the L-shaped rod 43 and the fork 41 and the slider 42. The length of the third line segment 43a is greater than the length of the first line segment 42a (formed by connecting the two hinge points of the slider 42), allowing the fork 41 to pass through the slider 42 without interference.

[0036] See also Figure 3 Because the equipment rack 1 has supporting casters 1a at its bottom, there is still some distance between the equipment rack 1 and the ground. Accordingly, when the slider 42 is at its lower limit, there is still some distance between the equipment rack 1 and the ground. As the slider 42 descends, the fork 41 swings downward relative to the slider 42, allowing the fork 41 to be lower than the slider 42.

[0037] Preferably, when the fork 41 is at the lower limit position, the bottom surface of the fork 41 can be flush with the supporting caster 1a, that is, the fork 41 touches the ground. In this way, the fork 41 is supported by the ground, and the fork 41 is more stable when the cloth roll rolls from the ground into the fork 41.

[0038] See also Figure 5 Because equipment rack 1 houses scale 2 in weighing area 1b, scale platform 2a moves downward during the weighing process. Therefore, to prevent equipment rack 1 from interfering with the operation of scale 2, a gap remains between equipment rack 1 and scale platform 2a. Accordingly, a gap also remains between slider 42 and the ground when it is in its upper position. As slider 42 rises, fork 41 swings upward relative to slider 42, allowing fork 41 to rise above slider 42.

[0039] That is to say, through the swing of the fork 41 relative to the slider 42, the up and down movement range of the fork 41 is further expanded on the basis of the up and down movement range of the slider 42, meeting the loading needs of the cloth roll rolling from the ground into the fork 41 and the unloading needs of the cloth roll rolling from the fork 41 into the weighing platform 2a.

[0040] The linear mechanism 52 can adopt existing driving mechanisms such as hydraulic cylinders, linear modules, and winch motors.

[0041] See also Figure 8In some embodiments, because the connection portion 51 requires two limits, a first position and a second position, the linear mechanism 52 preferably utilizes a hydraulic cylinder. The two travel limits of the hydraulic cylinder piston rod correspond to the first position and the second position, respectively. The hydraulic cylinder body can be fixedly connected to the equipment frame 1. More specifically, each end of the hydraulic cylinder can be fixedly connected to an L-shaped base, which is fixedly connected to the equipment frame 1 via screws. Accordingly, the hydraulic cylinder piston rod is fixedly connected to the connection portion 51.

[0042] As an actuator, the hydraulic cylinder needs to be used in conjunction with a corresponding hydraulic system. The solenoid valve in the hydraulic system controls the movement path of the oil in the oil circuit and the hydraulic cylinder body, thereby controlling the extension, retraction and stay of the hydraulic cylinder piston rod.

[0043] See also Figure 8 In some embodiments, based on the above-mentioned “the hydraulic cylinder piston rod is fixedly connected to the connecting portion 51”, the hydraulic cylinder piston rod has a threaded section 52a, the connecting portion 51 has a through hole for the threaded section 52a to pass through, and the threaded section 52a is threadedly connected with nuts 52b on both sides of the connecting portion 51.

[0044] The fork 41 is connected to the scale 2 in such a way that it can be flush with, slightly above, or slightly below the weighing platform 2a of the scale 2. This means that the upper limit position of the fork 41 can be somewhat floating. Preferably, the fork 41 contacts the ground when in the lower limit position. In this configuration, the lower limit position of the fork 41 is fixed. To securely connect the hydraulic cylinder piston rod to the connecting portion 51, first allow the fork 41 to contact the ground under the action of gravity. Next, extend the hydraulic cylinder piston rod through the connecting portion 51. Finally, tighten the two nuts 52b to secure the hydraulic cylinder piston rod to the connecting portion 51.

[0045] Use two sets of loading components 4 to place the cloth roll from the ground to the weighing platform 2a of the scale 2: S1, the forks 41 are at the lower limit position, the cloth roll is on the ground, and the cloth roll is manually pushed to roll onto the two forks 41; S2, manually start the driving assembly 5, and the two forks 41 lift the cloth roll; S3. Manually push the cloth roll to make it roll onto the weighing platform 2a of the scale 2.

[0046] During the swinging motion of the fork 41, its movement can be broken down into both vertical and horizontal movements. The vertical movement is used to lift the fabric roll, while the horizontal movement causes relative movement between the fabric roll and the fork 41, affecting the stability of the fabric roll on the fork 41. Because the horizontal movement of the fork 41 is limited, the speed of the hydraulic cylinder piston rod can be slowed down to allow for manual support of the fabric roll on the fork 41. Alternatively, the top surface of the fork 41 can be designed with a slight inclination (for example, 1 degree). Even if this affects the stability of the fabric roll on the fork 41, gravity will cause the fabric roll to roll toward the equipment frame 1.

[0047] See also Figure 6 In some embodiments, the top surface of the slider 42 has a stopper 42c, which is located on the side of the scale 2 laterally away from the fork 41. When the connecting portion 51 is in the second position, the stopper 42c extends beyond the scale 2, that is, the stopper 42c is higher than the weighing platform 2a of the scale 2.

[0048] In the above step S2, the connecting portion 51 moves from the first position to the second position, so that the blocking rod 42c extends beyond the scale 2. In the subsequent step S3, when the cloth roll enters the weighing platform 2a of the scale 2, the blocking rod 42c acts as a barrier to prevent the cloth roll from rolling out of the weighing platform 2a.

[0049] See also Figure 10 In some embodiments, the loading assembly 4 further includes: a triangular plate 45 and an L-shaped groove rail 46.

[0050] See also Figure 12 and Figure 13 The L-shaped groove rail 46 is fixedly connected to one longitudinal side of the equipment rack 1. More specifically, the L-shaped groove rail 46 and the equipment rack 1 can be welded and fixed.

[0051] See also Figure 11 The first corner 45a of the triangular plate 45 and the L-shaped groove rail 46 form a first groove pin pair, that is, the first corner 45a of the triangular plate 45 can move relative to the L-shaped groove rail 46 and can also swing relative to the L-shaped groove rail 46. More specifically, the first corner 45a of the triangular plate 45 can be installed with a first guide wheel 45a1, and the diameter of the first guide wheel 45a1 is equal to the width of the L-shaped groove rail 46.

[0052] The second corner 45b of the triangular plate 45 and the vertical section of the L-shaped groove rail 46 form a second groove pin pair. More specifically, referring to the first corner 45a of the triangular plate 45, a second guide wheel 45b1 may be mounted on the first corner 45a of the triangular plate 45. The diameter of the second guide wheel 45b1 is equal to the diameter of the first guide wheel 45a1. Compared to the first guide wheel 45a1, the second guide wheel 45b1 can be wider. Accordingly, the vertical section of the L-shaped groove rail 46 can be deeper than the horizontal section of the L-shaped groove rail 46. This allows the first guide wheel 45a1 to enter the vertical section of the L-shaped groove rail 46 from the horizontal section, while the second guide wheel 45b1 only remains in the vertical section of the L-shaped groove rail 46.

[0053] See also Figure 11 and Figure 13 The fork 41 has a transverse horizontal groove 41b, and the third corner 45c of the triangular plate 45 and the horizontal groove 41b form a third groove pin pair. More specifically, the third corner 45c of the triangular plate 45 can be installed with a needle bearing 45c1, and the outer ring diameter of the needle bearing 45c1 is equal to the width of the horizontal groove 41b.

[0054] See also Figure 12 , when the connecting portion 51 is in the first position and the fork 41 is in the lower limit position: The first corner 45 a of the triangular plate 45 corresponds to the horizontal section of the L-shaped groove rail 46 ; more specifically, the first corner 45 a of the triangular plate 45 corresponds to the horizontal section of the L-shaped groove rail 46 , and more specifically, may correspond to the bottom of the horizontal section of the L-shaped groove rail 46 .

[0055] The connecting portion 51 moves from the first position to the second position, and the fork 41 swings from the lower limit position to the upper limit position. During this process: See also Figure 10 and Figure 13 The first corner 45a of the triangular plate 45 moves along the horizontal section of the L-shaped groove rail 46, and the direction is close to the vertical section of the L-shaped groove rail 46; the second corner 45b of the triangular plate 45 moves synchronously along the vertical section of the L-shaped groove rail 46, and the direction is upward. The triangular plate 45 rotates, and the third corner 45c of the triangular plate 45 slides relative to the horizontal groove rail 41b to adapt to the rotation of the triangular plate 45 and the horizontal displacement of the fork 41 during the swing process.

[0056] The first corner 45a of the triangular plate 45 enters the vertical section of the L-shaped groove rail 46, and the first corner 45a and the second corner 45b of the triangular plate 45 both move along the vertical section of the L-shaped groove rail 46 in an upward direction. The triangular plate 45 moves upward, and the third corner 45c of the triangular plate 45 slides relative to the horizontal groove rail 41b to adapt to the horizontal displacement of the fork 41 during the swinging process.

[0057] The fabric roll placement fork 41 exerts a downward torque on the fork 41, requiring support from the hinges between the fork 41 and the L-shaped rod 43, and between the fork 41 and the connecting rod 44, to balance the load. These hinges are relatively far from the fabric roll placement position on the fork 41. In particular, when the L-shaped rod 43 and the connecting rod 44 overlap, the forces at the hinges between the fork 41 and the L-shaped rod 43, and between the fork 41 and the connecting rod 44, are greatest.

[0058] The addition of triangular plate 45 allows it to be closer to the position where the fabric roll is placed on the fork 41, providing support for the fork 41. Specifically, after the first corner 45a of triangular plate 45 enters the vertical section of the L-shaped groove 46, the rotation of triangular plate 45 is restricted. The first and second rollers can both abut against the inner wall of the vertical section of the L-shaped groove 46, allowing the third corner 45c of triangular plate 45 to provide stable support for the fork 41. Furthermore, through proper design, the first corner 45a of triangular plate 45 can enter the vertical section of the L-shaped groove 46 just before the L-shaped rod 43 and connecting rod 44 approach overlap.

[0059] See also Figure 10 and Figure 11 In some embodiments, the triangular plate 45 further corresponds to an obtuse triangle, and the second angle 45b corresponds to an obtuse angle.

[0060] Regarding the above “in order to prevent the equipment frame 1 from interfering with the operation of the scale 2, there is still a distance between the equipment frame 1 and the weighing platform 2a”, if the triangular plate 45 corresponds to a right-angled or acute-angled triangle, after the first corner 45a of the triangular plate 45 enters the vertical section of the L-shaped groove rail 46, the third corner 45c of the triangular plate 45 is flush with or lower than the second corner 45b of the triangular plate 45, and the third corner 45c of the triangular plate 45 needs to exceed the equipment frame 1 upward together with the fork 41, resulting in the need for the vertical section of the L-shaped groove rail 46 to be able to retract, which makes the structure more complicated and reduces the supporting effect on the fork 41.

[0061] The triangular plate 45 corresponds to an obtuse triangle. After the first corner 45a of the triangular plate 45 enters the vertical section of the L-shaped groove 46, the third corner 45c of the triangular plate 45 is higher than the second corner 45b of the triangular plate 45. By utilizing this height difference, the third corner 45c of the triangular plate 45 and the fork 41 can move upward over the equipment frame 1 together, and the vertical section of the L-shaped groove 46 can guide the second corner 45b of the triangular plate 45 without extending or retracting.

[0062] See also Figure 14 In some embodiments, the cloth roll elevator further includes a placement plate 6 , which is fixedly connected between the two forks 41 .

[0063] For some soft material cloth roll, two forks 41 support cloth roll both ends of the position will be cloth roll lifted, cloth roll in the middle of the gravity easy to bend and indentation, affect the subsequent cloth roll rolling, into the scale 2 scale table 2a, also may cause cloth roll from the two forks 41 in the middle of the fall.
