Description

Technical Field

[0001] The utility model relates to the technical field of coil wire packaging equipment, in particular to a single-layer or double-layer figure eight wrapping machine. Background Art

[0002] During the production and processing of cables, the finished cables are often wound into coils, and then wrapped with packing tape, PE / PP film, etc. to reduce the looseness of the cables during storage and transportation. Currently, most manufacturers use mechanical equipment to pack the coils. One of the packaging methods is to use a trolley rotating on a circular track to pack the ring-shaped object. The trolley carries the wrapping film and rotates on the circular track to complete the wrapping of the ring-shaped object.

[0003] For example, a Chinese utility model patent (publication number CN206954574U) discloses a multi-station packaging equipment for packaging annular objects, including a base, a transverse movable frame arranged on the upper part of the base and moving along the base, a longitudinal movable frame arranged on the upper part of the transverse movable frame and moving along the transverse movable frame, a circular runway installed on the longitudinal movable frame, a packaging trolley arranged in the circular runway, and a plurality of packaging stations distributed near the base. The utility model performs packaging by a trolley rotating on a circular track. The trolley carries a wrapping film and rotates on the circular track to complete the wrapping of the annular object, and multiple packaging stations are set. When a packaging station completes packaging, the circular runway opens and exits the packaging station. The transverse movable frame moves to other stations with the longitudinal movable frame and the circular runway on the longitudinal movable frame to continue packaging, thereby shortening the packaging time. Although the above structure can realize automatic packaging of coiled wire, it has the following disadvantages:

[0004] 1. When packaging the coiled wire at a single station, since there is only one track, the trolley needs to drive the stretch film to wrap the coiled wire 360°, and sometimes in order to improve the packaging strength of the coiled wire, the coiled wire needs to be double-wrapped. The entire packaging process takes a long time, which is not conducive to improving work efficiency.

[0005] 2. During transportation, the wrapping film that wraps the coiled wire is easily vibrated or squeezed and deformed, and the wrapping film may become loose. Therefore, after the wrapping film is completed, it is necessary to stick another circle of tape around the wrapping film to prevent the wrapping film from loosening. Currently, the wrapping film is usually manually pasted with tape after the coiled wire is wrapped with wrapping film, which is labor-intensive and inefficient.

[0006] 3. Since the height of the circular runway is fixed and cannot be adjusted, once the radius of the coil is too large or too small, the circular track cannot accurately pass through the center hole of the coil. Therefore, only coils with a fixed radius can be packaged, which limits the scope of use. Utility Model Content

[0007] The purpose of the utility model is to overcome the shortcomings of the above-mentioned background technology and provide a single- and double-layer figure-eight wrapping machine. The wrapping machine adopts a double-track structure, and two trolleys wrap the winding film on the wire coil at the same time, which can reduce the wire coil packaging time on a single workstation by half, greatly improve the wire coil packaging efficiency, and can automatically stick tape on the periphery of the winding film, reducing manual labor intensity. The vertical height position of the track can also be adjusted to adapt to wire coil packaging operations with different radius sizes.

[0008] The technical solution provided by the utility model is:

[0009] A single- and double-layer figure-eight wrapping machine comprises a frame, a track fixed on the frame, a trolley which can move along the track and carries a winding film, and a wire coiling support seat arranged below the track; the characteristics are: the track comprises a first track and a second track which are arranged horizontally and are arranged in a ring shape; the first track and the second track are combined into an 8-shape, and the part between the two tracks forms an intermediate connecting part; the first track and the second track are both arranged into movable openings so that the intermediate connecting part passes through the center hole of the wire coil; the trolley comprises a first trolley and a second trolley which move respectively along the first track and the second track.

[0010] The first track and the second track both include a fixed part fixed on the frame, a movable part hinged to the fixed part, and a hydraulic rod driving the movable part to swing; one end of the hydraulic rod is hinged to the fixed part, and the other end is fixedly connected to the movable part.

[0011] The middle connecting part is arranged in a straight line; the first track and the second track are symmetrically arranged on both sides of the middle connecting part.

[0012] The wire coiling support seat comprises a base, two power rollers which are parallel to each other and rotatably positioned on the base to support the wire coiling, and a driving assembly which drives the two power rollers to rotate synchronously.

[0013] The frame is provided with a tape roll mounting frame corresponding to the coiling working position; the tape roll mounting frame comprises a support rod fixed on the frame and a winding rod horizontally fixed on the support rod for placing the tape roll; the axis of the winding rod is parallel to the axis of the power roller.

[0014] A first translation device is provided at the bottom of the wire coiling support seat; the first translation device includes a first transverse guide rail and a first longitudinal guide rail which are perpendicular to each other; the base can be movably positioned on the first transverse guide rail; the first transverse guide rail can be movably positioned on the first longitudinal guide rail.

[0015] A second translation device is provided at the bottom of the frame; the second translation device comprises a second transverse guide rail and a second longitudinal guide rail which are perpendicular to each other; the frame can be movably positioned on the second transverse guide rail; the second transverse guide rail can be movably positioned on the second longitudinal guide rail.

[0016] A height-adjusting guide rail is vertically arranged on the frame; the first rail and the second rail can be movably positioned on the height-adjusting guide rail.

[0017] The first trolley and the second trolley are both provided with a battery, a driving module, a power alarm module and a remote control module; the power alarm module includes a battery detection circuit, a buzzer and an alarm light.

[0018] The driving assembly adopts belt transmission or chain transmission.

[0019] The beneficial effects of the utility model are:

[0020] 1. The utility model adopts a double track structure combined into an 8-shape, and a trolley is arranged in each track.

DETAILED DESCRIPTION

[0030] The following is a further description with reference to the embodiments shown in the accompanying drawings.

[0031] like Figure 1 The single-layer double-layer figure-eight wrapping machine shown includes a frame 1, a track, a trolley and a coil support seat 4. The track is fixed on the frame 1, and the track includes a first track 2-1 and a second track 2-2 arranged horizontally and arranged in a ring shape. The first track 2-1 is provided with a first trolley 3-1 that can move along the track, and the second track 2-2 is provided with a second trolley 3-2 that can move along the track. The first track 2-1 and the second track 2-2 are combined into an 8-shaped shape, wherein the portion between the first track 2-1 and the second track 2-2 forms an intermediate connecting portion 2-3. Preferably, the intermediate connecting portion 2-3 is arranged in a straight line, and the first track 2-1 and the second track 2-2 are symmetrically arranged on both sides of the intermediate connecting portion 2-3. When working, the intermediate connecting portion 2-3 passes through the central hole 5-1 of the coil 5. At this time, the first trolley 3-1 and the second trolley 3-2 can wrap the carried winding film on the coil 5 when they move in a ring along their respective tracks.

[0032] like Figure 1 , Figure 2As shown, the first track 2-1 and the second track 2-2 are both configured to be movable so as to smoothly take and place the coil line 5. The first track 2-1 and the second track 2-2 both include a fixed portion 2-4, a movable portion 2-5 and a hydraulic rod 2-6; the fixed portion 2-4 is fixed on the frame 1; the movable portion 2-5 is hinged to the fixed portion 2-4; the hydraulic rod 2-6 is arranged on the outer side of the track and drives the movable portion 2-5 to swing. One end of the hydraulic rod 2-6 is hinged to the fixed portion 2-4, and the other end is fixedly connected to the movable portion 2-5. In this embodiment, a first connecting block 2-7 is arranged on the outer side of the fixed portion 2-4, and a second connecting block 2-8 is arranged on the outer side of the movable portion 2-5. One end of the hydraulic rod 2-6 is hinged to the first connecting block 2-7, and the other end is fixedly connected to the second connecting block 2-8. During operation, the wire coil 5 needs to enter or exit from the middle connection part before or after the packaging operation. At this time, the hydraulic rod 2-6 is driven (the hydraulic rod 2-6 is retracted in the figure) to open the movable part 2-5, so that the wire coil 5 can be taken in and out. During the packaging operation of the wire coil 5, it is necessary to ensure that the first track 2-1 and the second track 2-2 are closed. At this time, the hydraulic rod 2-6 is driven (the hydraulic rod 2-6 is extended in the figure) and the movable part 2-5 remains closed, so that the trolley can run smoothly along the track and carry the wrapping film to wrap the wire coil 5.

[0033] The first trolley 3-1 and the second trolley 3-2 are both provided with a battery, a drive module, a power alarm module and a remote control module. Since the trolley is powered by a battery, compared with the common method of using a slip ring to move along the cable to power the trolley, it can avoid the problem of cable entanglement and tangling, and improve the flexibility of the trolley. The remote control module can use a Wi-Fi module, a Bluetooth module, an RFID module, and an infrared module to remotely send instructions to the trolley through a remote control. After receiving the instructions, the remote control module controls the movement or parking of the trolley through the drive module. The trolley also has a power alarm function, wherein the power alarm module includes a battery detection circuit, a buzzer and an alarm light; when the battery detection circuit detects that the battery is low on power, the buzzer sounds an alarm and the alarm light flashes, thereby promptly reminding the staff to charge the battery to avoid affecting the normal packaging operation of the coiled wire. The above-mentioned battery, drive module, power alarm module, remote control module, and remote control can all be purchased from outside, and are not shown in the figure.

[0034] like Figure 3As shown, the wire coil support seat 4 is arranged below the track to support the wire coil 5. The wire coil support seat 4 includes a base 4-1, two power rollers 4-2 and a drive assembly (not shown in the figure). The two power rollers 4-2 are parallel to each other and rotatably positioned on the base 4-1. The drive assembly is used to drive the two power rollers 4-2 to rotate synchronously; the drive assembly includes a motor fixed to the base, the motor drives one of the power rollers to rotate, and drives the other power roller to rotate through a belt drive or a chain drive.

[0035] like Figure 1 , Figure 2 As shown, the frame 1 is provided with a tape roll mounting frame, and the position of the tape roll mounting frame corresponds to the working position of the coiling line, so that the tape can be smoothly pasted to the circumferential position of the coiling line. The tape roll mounting frame includes a support rod 6-1 and a roll rod 6-2; the support rod 6-1 is fixed on the frame 1; the roll rod 6-2 is horizontally fixed on the support rod 6-1, and is used to place the tape roll 6-3; preferably, the axis of the roll rod 6-2 is parallel to the axis of the power roller 4-2. In this embodiment, the roll rod is located on the side of the support rod, one end of the roll rod is fixed to the support rod by a threaded fastener, and the other end of the roll rod is suspended, so that the tape roll can be taken and placed from the suspended end of the roll rod. During work, the staff only needs to stick one end of the tape to the circumferential position of the coiling line 5, and the coiling line 5 is driven to rotate by the power roller 4-2, and the tape roll 6-3 will be automatically pulled and stuck to the coiling line 5, and the tape pasting operation can be automatically completed, reducing the labor intensity of manual tape pasting and improving packaging efficiency.

[0036] like Figure 1As shown, a first translation device is provided at the bottom of the cable support seat 4; the first translation device includes a first transverse guide rail 7-1 and a first longitudinal guide rail 7-2 which are perpendicular to each other; the base 4-1 can be movably positioned on the first transverse guide rail 7-1; the first transverse guide rail can be movably positioned on the first longitudinal guide rail 7-2. A second translation device is provided at the bottom of the frame 1; the second translation device includes a second transverse guide rail 8-1 and a second longitudinal guide rail 8-2 which are perpendicular to each other; the frame 1 can be movably positioned on the second transverse guide rail 8-1; the second transverse guide rail 8-1 can be movably positioned on the second longitudinal guide rail 8-2. The frame 1 is vertically provided with a height adjustment rail 9; the first rail 2-1 and the second rail 2-2 can be movably positioned on the height adjustment rail 9; when the radius of the wire coil 5 is too large or too small, the intermediate connection part 2-3 cannot accurately correspond to the center hole 5-1 of the wire coil 5, and the height of the frame 1 can be adjusted by the height adjustment rail 9, so that the intermediate connection part 2-3 and the center hole 5-1 of the wire coil 5 are adapted in height. During operation, the horizontal position of the wire coil 5 can be adjusted by the first translation device, the horizontal position of the track can be adjusted by the second translation device, and the vertical position of the track can be adjusted by the height adjustment rail 9, so as to ensure that the intermediate connection part 2-3 accurately corresponds to the center hole 5-1 of the wire coil 5, and can adapt to the packaging operation of wire coils 5 of different radius sizes. It should be noted that in this embodiment, the translation device is provided at the wire coil support seat 4 and the bottom of the frame 1, and only one set of translation devices can be provided according to actual needs, that is, the wire coil 5 is fixed and the track is horizontally adjustable, or the horizontal position of the wire coil 5 is adjustable and the horizontal position of the track is fixed.

[0037] The utility model of the wrapping machine can quickly wrap the coiled wire with a single or double layer of winding film. Through the simultaneous operation of two trolleys, the coiled wire packaging time of a single station is reduced by half, greatly improving the coiled wire packaging efficiency. The specific working method is as follows:

[0038] Before packaging the wire coil 5, the vertical height of the frame 1 is adjusted according to the radius of the wire coil 5, so that the track height is adapted to the height of the center hole 5-1 of the wire coil 5; the hydraulic rod 2-6 on the outside of the first track 2-1 and the second track 2-2 is contracted to drive the movable portion 2-5 to swing, so that the movable portions 2-5 of the two tracks are opened; the horizontal positions of the wire coil 5 and the tracks are adjusted by the first translation device and the second translation device, the middle connecting portion 2-3 is aligned with the center hole 5-1 of the wire coil 5, and the wire coil 5 is inserted into the middle connecting portion 2-3 to the working position; the hydraulic rod 2-6 on the outside of the first track 2-1 and the second track 2-2 is extended to drive the movable portion 2-5 to swing, so that the two tracks are closed, and the wire coil 5 can be wrapped with stretch film.

[0039] When the coiled wire 5 is being packaged, the driving assembly drives the two power rollers 4-2 to rotate, thereby driving the coiled wire 5 to rotate; at the same time, the first trolley 3-1 and the second trolley 3-2 are remotely controlled by the remote controller, so that the two trolleys carry the wrapping film to wrap the coiled wire 5. The speed of the trolley 5 is consistent with the speed at which the power roller 4-2 drives the coiled wire 5 to rotate, so as to ensure that the wrapping film wrapped on the coiled wire 5 is uniform and compact, thereby improving the packaging quality of the coiled wire 5. When the wrapping film is used to wrap the coiled wire 5, the remote controller controls the trolley to stop moving. The tape roll is mounted on the reel 6-2, and the staff only needs to stick one end of the tape to the circumferential position of the coiled wire 5. After that, when the power roller 4-2 drives the coiled wire 5 to rotate, the tape roll 6-3 will be automatically pulled and stuck to the coiled wire 5, thereby realizing the automatic tape sticking operation and reducing the labor intensity of manual tape sticking.

[0040] After the coil wire 5 is packaged, the hydraulic rod 2-6 outside the first track 2-1 and the second track 2-2 contracts to drive the movable part 2-5 to swing, so that the movable parts 2-5 of the two tracks are opened; the coil wire is withdrawn from the middle connecting part 2-3 through the first translation device and the second translation device, and the entire packaging operation of the coil wire 5 can be completed.

[0041] In addition, when the wrapping machine of the present invention is in use, if the central hole 5-1 of the coiled wire 5 is too small to pass through two trolleys at the same time, one of the trolleys can be driven to move independently, thereby flexibly adapting to packaging operations of coiled wires of different styles.

[0042] It should be noted that the wrapping machine of the present invention is not only suitable for packaging coiled wires, but can also be used for packaging other annular objects (such as metal coils, etc.).

[0043] The above examples are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above examples, and many variations are possible. All variations that can be directly derived or associated with the contents disclosed by a person skilled in the art from the present invention should be considered as the protection scope of the present invention.
