Description

Technical Field

[0001] The present invention relates to the technical field of loading and unloading equipment, and in particular to an automatic loading and unloading machine and an automatic loading and unloading device suitable for coiled material passing through a core shaft. Background Art

[0002] Existing wide plastic coils are typically wound around an iron drum equipped with a through-shaft to facilitate transport. However, due to the heavy weight (200 to 400 kilograms) of the iron drum through-shaft used to wind wide plastic coils, loading and unloading them is typically done by towing with a crane or using an electric winch. This process is inconvenient, labor-intensive, and inefficient, posing safety risks. Summary of the Invention

[0003] The object of the present invention is to provide an automatic loading and unloading machine and an automatic loading and unloading device suitable for coiled material passing through a core shaft, so as to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solutions adopted to solve the above technical problems are:

[0005] First, the present invention provides an automatic loading and unloading machine suitable for coiled material passing through a core shaft, which includes: a movable frame, a core pulling frame, a lifting drive mechanism, a core pulling mechanism and a blocking and rolling mechanism, the core pulling frame is arranged on the movable frame; the lifting drive mechanism is provided with a lifting drive end which is transmission-connected to the core pulling frame and enables the core pulling frame to lift up and down relative to the movable frame, the core pulling mechanism is provided on the core pulling frame, the core pulling mechanism includes a core pulling transverse driving assembly and a fork frame, the core pulling transverse driving assembly is provided with a transverse driving end which is transmission-connected to the fork frame and enables the fork frame to move left and right relative to the core pulling frame; the blocking and rolling mechanism includes a push plate provided on one of the end portions in the left and right directions of the core pulling frame.

[0006] When the core-penetrating shaft in the iron cylinder for winding the wide plastic coil is pulled out, the lifting drive mechanism drives the core-pulling frame to move upward relative to the movable frame, so that the shift fork frame is engaged with the card slot at the end of the core-penetrating shaft, and the push plate supports the end face of the coil. Then the core-pulling transverse driving assembly drives the shift fork frame to move in the left and right directions relative to the core-pulling frame, and the shift fork frame pulls the core-penetrating shaft out of the wide plastic coil and onto the core-pulling frame. When the core-penetrating shaft is loaded into the iron cylinder for winding the wide plastic coil, the movable frame is moved to an appropriate position, and the core-pulling transverse driving assembly drives the shift fork frame to rise and fall so that the end of the core-penetrating shaft is aligned with the end of the iron cylinder. Then the core-pulling transverse driving assembly drives the shift fork frame to move in the left and right directions relative to the core-pulling frame, and the shift fork frame drives the core-penetrating shaft to be loaded into the iron cylinder, thereby realizing automatic loading and unloading of the core-penetrating shaft of the coil.

[0007] As a further improvement to the above technical solution, a shaft supporting mechanism is provided on the core pulling machine frame, and the shaft supporting mechanism includes rollers arranged on the lateral movement track of the shift fork frame. Due to the relatively heavy and long core-penetrating shaft, in order to make the core-penetrating shaft move more smoothly, the present solution provides a shaft supporting mechanism on the core pulling machine frame, and the shaft supporting mechanism supports the core-penetrating shaft via rollers.

[0008] As a further improvement of the above technical solution, the shaft support mechanism also includes a shaft support swing frame and a swing drive assembly. The shaft support swing frame is provided with a shaft support end and a swing end. The shaft support swing frame is arranged below the transverse movement track of the fork frame. The roller wheel is installed on the shaft support end. The swing drive assembly is provided with a swing drive end that is connected to the swing end so that the shaft support end swings around the axis along the front and rear directions. The shaft support swing frame is arranged on the side close to the blocking mechanism.

[0009] The roller wheel in this solution is installed on the support shaft end of the support shaft swing frame. This is mainly due to the balance of the through-core shaft. Since the fork frame pulls and supports one end of the through-core shaft at the same time, there is no need to support the through-core shaft in the front section when the through-core shaft is pulled out, because the coiled material can also support the other end of the through-core shaft. When the through-core shaft is pulled out for a section, that is, after passing the position of the support shaft swing frame, the swing drive component drives the support shaft end to swing around the axis along the front-to-back direction, so that the support shaft end swings, and the roller wheel supports the through-core shaft to avoid the through-core shaft from tipping over after being completely pulled out.

[0010] As a further improvement of the above technical solution, the support shaft swing frame is rotatably mounted on the core pulling machine frame through a swing shaft extending forward and backward, and the swing shaft is arranged between the support shaft end and the swing end. The swing drive assembly includes a swing telescopic drive unit, one end of the swing telescopic drive unit is hinged to the core pulling machine frame, and the other end of the swing telescopic drive unit is hinged to the swing end.

[0011] The support shaft swing frame in this solution is rotatably mounted on the core pulling machine frame through a swing shaft, which can improve the load-bearing capacity of the support shaft swing frame and also simplify the structure of the swing drive assembly. At this time, the swing drive assembly only needs a linear swing telescopic drive unit, which drives the swing end on the support shaft swing frame to rotate, thereby driving the support shaft end to swing.

[0012] As a further improvement of the above technical solution, the fork frame is connected to the core pulling frame for left and right sliding. The core pulling transverse movement drive assembly includes two sprockets respectively installed on the left and right ends of the core pulling frame, a chain connected between the two sprockets, and a core pulling motor connected to one of the sprockets. The fork frame is connected to the chain.

[0013] The core pulling transverse driving assembly in this scheme adopts a structure driven by a chain and a sprocket. Specifically, the core pulling motor drives one of the sprockets to rotate, thereby driving the chain to move. At this time, the chain drives the fork frame to move left and right along the core pulling frame, and the fork frame is connected to the core pulling frame for sliding left and right, which can improve the carrying capacity of the fork frame.

[0014] As a further improvement to the above technical solution, a transverse pulley assembly is provided at the bottom of the shift fork frame, a transverse slide is provided on the core pulling machine frame, the transverse pulley assembly and the transverse slide are slidably engaged, and a semicircular shift fork latch is provided on the top of the shift fork frame. The shift fork frame in this solution engages with the latching slot at the end of the through-core shaft via the semicircular shift fork latch and supports the through-core shaft. The specific size is determined by the through-core shaft. The shift fork frame achieves left-right sliding engagement with the transverse slide on the core pulling machine frame via the transverse pulley assembly.

[0015] As a further improvement of the above technical solution, the core-pulling machine frame is connected to the movable frame for sliding up and down, and the lifting drive mechanism includes a lifting screw rod extending up and down on the movable frame, a nut seat connected to the lifting screw rod through a thread transmission, and a rotating drive assembly for driving the lifting screw rod to rotate, and the nut seat is fixedly mounted on the core-pulling machine frame.

[0016] The lifting drive mechanism in this solution drives the core pulling machine frame to move up and down through the threaded transmission of the lifting screw and the nut seat, which makes the up and down movement of the fork frame more precise and has better load-bearing capacity.

[0017] As a further improvement of the above technical solution, there are multiple lifting screws, and the multiple lifting screws are evenly distributed between the core pulling frame and the movable frame. The rotation drive assembly includes a rotating motor, a transmission shaft, multiple worms, and multiple worm wheels. The worm wheel is fixedly mounted on the lifting screw, and the worm and the transmission shaft are connected through a transmission bevel gear structure. The worm is engaged with the worm wheel, and the rotating motor is connected to the transmission shaft.

[0018] In this solution, multiple lifting screws and multiple nut seats are set between the core pulling frame and the movable frame, which can make the lifting of the core pulling frame more stable and avoid sinking of a certain part. In addition, with the transmission cooperation of the transmission shaft, transmission bevel gear structure, multiple worms and multiple worm wheels, the synchronous rotation of multiple lifting screws can be achieved through a rotating motor.

[0019] As a further improvement of the above technical solution, the roll blocking mechanism further includes a roll blocking drive component for driving the push plate to move horizontally left and right.

[0020] This solution uses a roll-blocking drive assembly to drive the push plate to move left and right. This is mainly because the coils are generally heavy and the surface needs to be protected, so they need to be placed stationary. During the loading and unloading process of the through-core shaft, the mobile frame needs to move forward and backward. If the push plate is stationary, a gap will be formed between the push plate and the end face of the coil, or the conveying of the coil is not accurate enough to just contact the push plate. When the through-core shaft is pulled, the through-core shaft will move the coil, which will damage the coil. In this solution, after the mobile machine moves into place or the coil is placed, the roll-blocking drive assembly drives the push plate to move outward until it contacts the end face of the coil.

[0021] In addition, the present invention also provides an automatic loading and unloading device suitable for coiled material passing through a core shaft, which includes the above-mentioned automatic loading and unloading machine, and also includes an iron cylinder rack, a coil rack, and a ground rail extending forward and backward. The push plate is arranged at the left end portion of the core pulling machine rack, and the iron cylinder rack and the coil rack are arranged at intervals front and back on the left side of the core pulling machine rack. The movable rack is connected to the ground rail in a front-back sliding manner.

[0022] The lifting mechanism drives the core-pulling frame to move upward relative to the mobile frame, so that the shift fork frame is engaged with the card slot at the end of the core-pulling shaft, and the push plate supports the end face of the coil, and then the core-pulling transverse driving assembly drives the shift fork frame to move in the left and right directions relative to the core-pulling frame, and the shift fork frame pulls the core-pulling shaft from the plastic wide roll and pulls it onto the core-pulling frame; and when the automatic loading and unloading device installs the core-pulling shaft, the iron cylinder frame is hoisted with the iron cylinder, and after the core-pulling shaft is completely pulled out, the mobile frame moves to the installation position, and the core-pulling transverse driving assembly drives the shift fork frame to rise and fall so that the end of the core-pulling shaft is aligned with the end of the iron cylinder, and then the core-pulling transverse driving assembly drives the shift fork frame to move in the left and right directions relative to the core-pulling frame, and the shift fork frame drives the core-pulling shaft to be inserted into the iron cylinder.

[0023] The beneficial effects of the present invention are: the coil material passing mandrel can be automatically withdrawn and installed, the operation is simple, convenient and safe, the efficiency is high, and the labor intensity of workers is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The core pulling mechanism is arranged on the core pulling frame 200, and the core pulling mechanism includes a core pulling transverse driving assembly and a fork frame 300. The core pulling transverse driving assembly is provided with a transverse driving end that is transmission-connected to the fork frame 300 and enables the fork frame 300 to move left and right relative to the core pulling frame 200. Specifically, the fork frame 300 is slidingly connected to the core pulling frame 200, and the core pulling transverse driving assembly includes two sprockets 310 respectively mounted on the left and right ends of the core pulling frame 200, a chain 320 connected between the two sprockets 310, and a core pulling motor connected to one of the sprockets 310. Machine 330, the fork frame 300 is connected to the chain 320, wherein the bottom of the fork frame 300 of this embodiment is provided with a transverse pulley assembly 340, and a transverse slide 210 is provided on the core pulling frame 200, the transverse pulley assembly 340 slides with the transverse slide 210, and the core pulling motor 330 drives one of the sprockets 310 to rotate, thereby driving the chain 320 to move. At this time, the chain 320 drives the fork frame 300 to move left and right along the core pulling frame 200, and the fork frame 300 is slidably connected to the core pulling frame 200 left and right, which can improve the carrying capacity of the fork frame 300.

[0039] The coil blocking mechanism includes a push plate 400 provided on one end portion of the core pulling machine frame 200 in the left and right directions. The push plate 400 is used to support the end surface of the coil.

[0040] like Figure 1 As shown, this embodiment also provides an automatic loading and unloading device suitable for coiled material passing through a core shaft, which adopts the above-mentioned automatic loading and unloading machine, and also includes an iron cylinder rack 700, a coil rack 800, and a ground rail 900 extending forward and backward. The iron cylinder rack 700 is used to support the placement of the iron cylinder, and the coil rack 800 is used to support the placement of the coiled material. The movable frame 100 is connected to the ground rail 900 in a front-back sliding manner, and the push plate 400 is arranged at the left end portion of the core pulling frame 200. The iron cylinder rack 700 and the coil rack 800 are arranged on the left side of the core pulling frame 200 at a front-back interval.

[0041] The push plate 400 of this embodiment is slidably matched with the core pulling frame 200 through the guide rod extending left and right, and the roll blocking drive assembly adopts a linear drive unit such as a cylinder and an electric push rod.

[0042] Furthermore, since the weight of the through-core shaft is relatively large and the length is long, in order to make the movement of the through-core shaft smoother, this embodiment provides a shaft support mechanism on the core pulling machine frame 200, and the shaft support mechanism supports the through-core shaft through the roller wheel 500. Specifically: the shaft support mechanism also includes a shaft support swing frame 510 and a swing drive assembly. The shaft support swing frame 510 is provided with a shaft support end 511 and a swing end 512. The shaft support swing frame 510 is provided below the transverse movement track of the fork frame 300, and the roller wheel 500 is installed on the shaft support end 511. The swing drive assembly is provided with a swing drive end that is connected to the swing end 512 for transmission, so that the shaft support end 511 swings around the axis along the front-back direction. The support shaft swing frame 510 is arranged on the side close to the blocking mechanism, and the roller wheel 500 is installed on the support shaft end 511 of the support shaft swing frame 510. This is mainly due to the balance of the through-core shaft. Since the fork frame 300 pulls and supports one end of the through-core shaft at the same time, there is no need to support the through-core shaft in the front section when the through-core shaft is pulled out, because the coiled material can also support the other end of the through-core shaft. When the through-core shaft is pulled out for a section, that is, after passing the position of the support shaft swing frame 510, the swing drive component drives the support shaft end 511 to swing around the axis along the front-back direction, so that the support shaft end 511 swings, allowing the roller wheel 500 to support the through-core shaft to avoid the through-core shaft from tipping over after being completely pulled out.

[0043] Among them, the support shaft swing frame 510 is rotatably mounted on the core pulling machine frame 200 through a swing shaft 520 extending forward and backward, and the swing shaft 520 is arranged between the support shaft end 511 and the swing end 512, and the swing drive assembly includes a swing telescopic drive unit 530, one end of the swing telescopic drive unit 530 is hinged to the core pulling machine frame 200, and the other end of the swing telescopic drive unit 530 is hinged to the swing end 512, and the support shaft swing frame 510 is rotatably mounted on the core pulling machine frame 200 through the swing shaft 520, which can improve the bearing capacity of the support shaft swing frame 510 and also simplify the structure of the swing drive assembly. At this time, the swing drive assembly only needs a linear swing telescopic drive unit 530, which drives the swing end 512 on the support shaft swing frame 510 to rotate, so as to drive the support shaft end 511 to swing. The swing telescopic drive unit 530 of this embodiment is a linear drive unit such as a cylinder or an electric push rod.

[0044] In addition, there are two idler rollers 500 , and the two idler rollers 500 are arranged in a V shape on the idler shaft end 511 .

[0045] In addition, a semicircular fork bayonet 350 is provided on the top of the fork frame 300. The fork frame 300 is engaged with the slot at the end of the through-core shaft through the semicircular fork bayonet 350 and supports the through-core shaft. The specific size is determined according to the through-core shaft.

[0046] To achieve automatic control, a limit switch and a photoelectric switch are provided on the core pulling frame 200 for detecting the lateral position of the shift fork frame 300. The photoelectric switch is provided in the middle of the core pulling frame 200. When the photoelectric switch detects the shift fork frame 300, the swing drive assembly drives the support shaft end 511 to swing around the axis in the front-to-back direction, causing the support shaft end 511 to swing, allowing the roller wheel 500 to support the core passing shaft. The limit switch mainly detects the leftmost and rightmost limits of the lateral movement of the inductive shift fork frame 300, so as to facilitate adjustment according to the length of the core passing shaft. A limit switch is also provided on the mobile frame 100 for detecting the lifting height of the inductive core pulling frame 200.

[0047] The process of the automatic loading and unloading device of this embodiment of the present invention is as follows: the working coil is hoisted onto the coil rack 800, the core pulling frame 200 is lowered, and the mobile frame 100 is moved to the unloading position, and the lifting drive mechanism drives the core pulling frame 200 to move upward relative to the mobile frame 100, so that the fork frame 300 is engaged with the card slot at the end of the core pulling shaft, and at the same time the roll blocking drive assembly drives the push plate 400 to support the end face of the coil, and then the core pulling transverse drive assembly drives the fork ... face of the core pulling shaft, and at the same time the fork frame 300 is engaged with the card slot at the end face of the core pulling shaft The fork frame 300 moves in the left and right directions relative to the core-pulling machine frame 200, and the fork frame 300 pulls the core-penetrating shaft out of the wide plastic roll. When the fork frame 300 moves to the middle position, the photoelectric switch controls the swing drive assembly to drive the support shaft end 511 to swing around the axis along the front-back direction, so that the support shaft end 511 swings, and the roller wheel 500 supports the air-penetrating core shaft to a balanced position. The fork frame 300 continues to move horizontally until the core-penetrating shaft is completely pulled onto the core-pulling machine frame 200.

[0048] The process of installing the through-core shaft in the automatic loading and unloading device of this embodiment is as follows: the replaced iron cylinder is hoisted onto the iron cylinder frame 700. After the through-core shaft is completely pulled out, the movable frame 100 is moved to the installation position. The core-pulling transverse driving assembly drives the fork frame 300 to rise and fall so that the end of the through-core shaft is aligned with the end of the iron cylinder. Then the core-pulling transverse driving assembly drives the fork frame 300 to move in the left and right directions relative to the core-pulling frame 200. The fork frame 300 drives the through-core shaft to be inserted into the iron cylinder. When the fork frame 300 moves to the middle position, the photoelectric switch controls the swing driving assembly to drive the support shaft end 511 to swing around the axis along the front-back direction, so that the support shaft end 511 swings downward, causing the roller wheel 500 to separate from the through-core shaft. The fork frame 300 continues to move transversely until the through-core shaft is completely loaded into the iron cylinder.

[0049] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments.
