Description

Technical Field

[0001] The present invention relates to a tape guiding device for a baler, and particularly to a circumferential and radial composite tape guiding device capable of adapting to different coil diameters. Background Art

[0002] For a full-automatic baler using steel tape as the packaging material, actions such as tape feeding, tape taking-up, tensioning, buckle making, and cutting are generally completed step by step. The steel tape winds around the object to be strapped for one week, and the strapping is completed after tightening and fixing. In order to enable the steel tape to automatically wind around the object to be strapped along the expected trajectory, a transmission device with tape guiding must be set. At the same time, during the process of tightening the steel tape, it can smoothly pop out from the tape guiding device, so that the steel tape can gradually fit the object to be strapped until it is tightened.

[0003] Currently, a fixed frame type tape guiding device with a tape guiding groove is generally adopted. The fixed frame type tape guiding device is simple, practical, and low in cost, but it can only be designed according to the maximum size when the size of the object to be strapped changes. The outer diameters of existing steel coils range from φ800 to φ2200, and the gap is too large. Therefore, when the fixed frame type tape guiding device is used for strapping small objects, the tape taking-up process is long, which affects the strapping efficiency. Even during the tape taking-up process, the phenomenon of steel tape deflection occurs, which affects the use of the baler and the packaging quality, resulting in a waste of time cost and affecting the overall rhythm of the small coil production line. For the axial through-hole strapping of annular cylindrical materials such as steel coils, the fixed frame type tape guiding device is also inapplicable. Summary of the Invention

[0004] In order to solve the problems and requirements in the background art, the present invention provides a circumferential and radial composite tape guiding device capable of adapting to different coil diameters. The device proposed by the present invention can adjust the actual use size of the tape guiding frame for baling, and can adapt to different heights of the coil cores, realizing equipment integration. It can simultaneously perform circumferential strapping and radial strapping on different coil diameters at the same station, and is particularly suitable for application in the technical field of full-automatic balers using steel tape as the packaging material.

When the rotating guide belt frame is opened, the reflector is not in the detection area and there is no signal feedback; when the rotating guide belt frame is closed, the ranging sensor has a signal and feeds back the distance data with the reflector, and if this data falls into the set interval, it indicates that the closing is completed. A turning cylinder 26 is also installed on the guide belt device lifting frame D where the rotating guide belt frame 22 is located, and the piston rod of the turning cylinder 26 is hinged to the top of the rotating guide belt frame 22. AsFigure 10 As shown, the piston rod of the flipping cylinder 26 moves upward and drives the rotating tape guide frame 22 to open outward, causing the bottom end of the rotating tape guide frame 22 to separate from the bottom end of the fixed tape guide frame 20 until the ear plate at the top of the rotating tape guide frame 22 cooperates with the rotating locking mechanism 24, that is, the ear plate hole position overlaps with the hole of the shaft seat assembly. As Figure 9 shown, the closing joint 29 includes a V-shaped joint 91 and a wedge-shaped joint 92. The V-shaped joint 91 is installed at the bottom end of the fixed tape guide frame 20, and the V-shaped joint 91 is installed at the bottom end of the rotating tape guide frame 22. The wedge angle is consistent with the V-shaped groove to correct the docking deviation caused by errors formed during manufacturing, installation, etc., and ensure accurate and firm docking after closing. Before entering the bundling station, the piston rod of the flipping cylinder 26 is in the retracted state, and the rotating tape guide frame is opened 90° at a high position, so that the overall tape guide frame can smoothly enter the axis of the package to be wrapped. It can be closed after reaching the designated position and remain closed during the bundling process to complete the radial tape guiding function. As Figure 7 and Figure 8 shown, the rotating locking mechanism 24 includes a rotating locking cylinder, a shaft seat assembly 41 and an ear plate 44. The rotating locking cylinder is fixedly connected to the lifting frame D of the tape guide device, the shaft seat assembly 41 is fixedly connected to the lifting frame D of the tape guide device, the shaft seat assembly 41 is hinged to the top of the rotating tape guide frame 22 through a rotating shaft and a shaft seat assembly 23, and the ear plate 44 is welded to the top of the rotating tape guide frame 22. The rotating shaft and the shaft seat assembly 23 include a rotating shaft 42 and a bearing 43. The rotating shaft 42 is installed in the shaft seat assembly 41 through the bearing 43, and the rotating shaft 42 is hinged to the top of the rotating tape guide frame 22. The ear plate welded to the rotating tape guide frame and the corresponding position of the shaft seat assembly are perforated, as Figure 10 shown, driven by the flipping cylinder 26, when the rotating tape guide frame rotates and rises to the highest position and the ear plate hole position overlaps with the hole of the shaft seat assembly, the piston rod of the rotating locking cylinder is pushed out and the safety pin is inserted to complete the locking. The function of the rotating locking mechanism is to ensure the accuracy of the position of the rotating tape guide frame in the open state and prevent the abnormal descent of the rotating tape guide frame under the action of gravity in the case of air loss of the cylinder, playing a safety protection role.

[0046] Figure 11 is a schematic diagram of the position state of the present invention in cooperation with a large-diameter steel coil. The circumferential-radial composite tape guide device cooperates with the bundling head at the highest position. Correspondingly, the overall frame of the sliding lifting type circumferential tape guide mechanism is relatively large, the circumference of the steel tape for completing one circle of circumferential tape threading is also relatively long, and it takes more time.

[0047] Figure 12 is a schematic diagram of the position state of the present invention in cooperation with a small-diameter steel coil. The circumferential-radial composite tape guide device cooperates with the bundling head at a relatively low position. Comparing Figure 11 , the overall frame of the corresponding sliding lifting type circumferential tape guide mechanism is relatively small, the circumference of the steel tape for completing one circle of circumferential tape threading is also relatively small, and it takes less time.

[0048] Figure 11 and Figure 12 shows that the centers of Coil E corresponding to large and small coils are at different height positions respectively, and the present invention can adapt by adjusting the lifting height.

[0049] The specific embodiments of the present invention for realizing a circumferential and radial composite tape guiding device that can complete one circumferential center punching and four radially evenly distributed punchings on a coil at the same station on a coil production line and can adapt to different coil diameters are as follows:

[0050] Figure 13 This is a schematic diagram of the application of the present invention for automatic strapping of coils. Coil E is placed on the rotating rubbing roller F. The circumferential and radial composite tape guiding device is fixed on the tape guiding device lifting frame. The circumferential and radial composite tape guiding device can move along the axial direction of the coil. The device in the figure has run to the strapping station. The left and right bayonet mechanisms of the sliding lifting type circumferential tape guiding mechanism have been closed, and the flipping mechanism of the opening and closing type radial tape guiding mechanism has also completed the flipping action. At this time, the circumferential and radial strapping of the coil can be started;

[0051] During operation, circumferential strapping is carried out first. At this time, the front tape outlet of the strapping head and the rear tape inlet of the strapping head are aligned with the sliding lifting type circumferential tape guiding mechanism to form a closed tape guiding groove. The steel tape is sent out from the front tape outlet of the strapping head. The tape guiding sequence is the first tape guiding frame mechanism 4, the first tape guiding angle assembly 5, the first tape guiding rod 6, the first bayonet tape blocking plate assembly 7, the first puncturing assembly 8, the left puncturing assembly 9, the second bayonet tape blocking plate assembly 10, the second tape guiding rod 11, the second tape guiding angle assembly 12, the second tape guiding frame mechanism 13, and finally returns to the tape inlet 2 of the strapping head to complete one round of tape threading. After the tape threading is completed, the strapping head installation device and the strapping head descend close to the coil to start taking in the tape, tightening the steel tape, making a buckle, and then cutting the steel tape. Thus, one circumferential strapping is completed. After the strapping head returns to the starting position, it waits for the next strapping signal.

[0052] After the circumferential strapping is completed, radial strapping is carried out on the coil. The strapping head rotates 90°, so that the front tape outlet and the rear tape inlet of the strapping head form a closed tape threading groove with the opening and closing type radial tape guiding mechanism. During operation, in the direction of the opening and closing type radial tape guiding mechanism of the strapping head, the steel tape is guided into the narrow tape inlet and then into the strapping head, and then passes through the front tape outlet of the strapping head, the radial tape guiding groove, and the rear inlet of the strapping head in sequence. After the tape threading is completed, the strapping head descends close to the coil, and a radial strapping action can be carried out.

[0053] Generally, multiple radial strappings are evenly distributed. Generally, the auxiliary machine on the production line rotates the coil by an angle and then can carry out the next radial strapping action, repeating the radial strapping process until all radial strapping requirements are completed.

[0054] The above specific embodiments are used to explain the present invention rather than limit the present invention. Any modifications and changes made to the present invention within the spirit and scope of the claims of the present invention fall within the protection scope of the present invention.
