Description

Technical Field

[0001] The utility model relates to the technical field of automatic packaging, in particular to a belt feeding buffer component, a belt feeding mechanism and a belt feeding device of a packaging machine. Background Art

[0002] In the prior art, when bundling and packaging rolled materials, it is necessary to align the strapping tape with a tape passing channel reserved for convenient bundling and packaging. For example, after a metal tube / metal roll is wound up, in order to ensure that the rolled material does not become loose, the strapping tape is used for bundling and packaging. The reel of the wound material is often designed with a tape passing channel. The strapping tape can pass through the tape passing channel to cross from one side of the wound material to the other side.

[0003] Currently, this type of packaging method that requires accurate passage through the belt channel is still in the manual packaging stage, but manual packaging has high labor costs and low work efficiency.

[0004] The inventor has designed an automatic baler that can replace manual baling. The automatic baler can be used to automatically bundle rolled materials. However, the position of the roll cannot be guaranteed to be exactly the same before baling each time, that is, there is a small angular deviation in the belt passage that needs to be passed through each time. As a result, the strapping tape cannot be inserted into the belt passage quickly and accurately when being fed. Utility Model Content

[0005] The utility model aims to provide a belt feeding buffer component of a baling machine, so as to solve the problem in the prior art that the strapping belt cannot be inserted quickly and accurately when the strapping belt is inserted into a belt passing channel by an automatic baling machine.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A strapping buffer assembly of a baling machine comprises a guide clamp which can clamp or release the strapping strap. The guide clamp is connected to a guide seat which is close to the discharge end of the guide clamp and is used to cooperate with an adjacent rib plate on a reel.

[0008] The principle and advantage of this solution are: since the belt-passing channel and the belt-threading transition groove will change slightly with the rotation of the reel, there are generally 2, 4 or 6 belt-passing channels and belt-threading transition grooves on the reel (in the prior art, the belt-passing channel and the belt-threading transition groove are one-to-one corresponding, and the positions are aligned, that is, the port of the belt-passing channel is connected to the belt-threading transition groove), but each time the reel stops after rotating, it cannot ensure that it stays in the same position every time, resulting in the guide clamp not being able to be fully aligned with the belt-passing channel, making it difficult to accurately insert the strapping tape.

[0009] This solution connects a guide seat to the guide clamp. When the guide clamp approaches the belt-passing channel, the guide seat guides the approaching process, thereby increasing the probability that the strapping tape on the guide clamp is aligned with the belt-passing channel, thereby facilitating the strapping tape to be quickly aligned with the belt-passing channel and facilitating quick strap insertion (inserting the strapping tape into the belt-passing channel).

[0010] Preferably, as an improvement, the guide clamp can swing on a provided mounting member, and first elastic members are symmetrically installed on both sides of the swing center of the guide clamp, one end of the first elastic member is fixed on the guide clamp, and the other end of the first elastic member is fixedly installed on the mounting member.

[0011] Beneficial effect: Through the provision of the first elastic member, the guide clamp can be automatically reset due to the first elastic member each time after swinging.

[0012] Preferably, as an improvement, the guide seat is slidably connected to the guide clamp, and the guide seat can move closer to or farther away from the guide clamp after sliding, and a second elastic member is installed between the guide seat and the guide clamp.

[0013] Beneficial effect: In order to avoid a hard collision between the guide clamp and the reel when the guide clamp approaches the belt passing channel, a second elastic member is designed so that during the approach process, before the guide clamp contacts the belt passing transition groove at the feed end of the belt passing channel, the guide seat has already contacted the belt passing transition groove, thereby reducing the intensity of the collision between the guide seat and the reel, thereby protecting the belt feeding buffer assembly when it approaches the belt passing channel.

[0014] Preferably, as an improvement, a position monitor is provided on the guide clamp, and the position monitor is used to monitor whether the strapping tape is delivered to a set position.

[0015] Beneficial effect: When this solution is adopted, the presence of the position monitor realizes the monitoring of the feeding position of the strapping belt, which is convenient for stopping the feeding of the strapping belt in time after the strapping belt accurately passes through the guide channel.

[0016] Preferably, as an improvement, the guide clamp is provided with a guide channel for guiding the feeding of the strapping tape, and the cross-sectional width of the guide channel gradually decreases from the feed end to the discharge end.

[0017] Beneficial effect: By continuously reducing the cross-sectional width of the guide channel, the strapping belt position is calibrated, thereby facilitating the strapping belt extending out of the guide channel to be accurately inserted into the belt passing channel with the cooperation of the guide seat and the first elastic member, thereby further improving the strapping belt threading efficiency.

[0018] This embodiment also provides a belt feeding mechanism of a baling machine, including the belt feeding buffer assembly.

[0019] Preferably, as an improvement, it further comprises a rotation driver for driving the guide clamp to rotate.

[0020] Beneficial effect: In this solution, the conveying direction of the strapping tape can be aligned with the tape passing channel only by rotating the guide clamp to a set angle under the rotary drive, and then the strapping tape can be accurately passed into the tape passing channel under the guidance of the guide clamp.

[0021] Preferably, as an improvement, it further comprises a traction assembly, which is used to traction and convey the packing belt.

[0022] This embodiment also provides a belt feeding device of a baling machine, including the belt feeding mechanism, and also includes a lifter for driving the guide clamp to rise and fall, and / or the guide clamp is eccentrically arranged with respect to the output center of the rotary drive.

[0023] Beneficial effect: This solution can make the strapping tape extending from the guide clip align with the tape passage, mainly by controlling the lifter to change the height of the strapping tape so as to align with the tape passage and / or by using an eccentric structure so that the end of the strapping tape after rotation can align with the tape passage.

[0024] Preferably, as an improvement, the traction assembly and the guide clamp are both mounted on a translator or a swing driver, the translator is used to drive the traction assembly and the guide clamp to translate along the width direction of the strapping belt, and the swing driver is used to drive the traction assembly and the guide clamp to move away from the strapping belt in a rotational manner, so as to prepare for tightening the strapping belt before the subsequent strapping buckle is tightened.

[0039] This embodiment is directed to the use of copper strapping tape for tape feeding and tape threading on a reel.

[0040] Example

[0041] Combination Figures 2 to 12 As shown, a belt feeding device of a baling machine comprises a lifter 1, a mounting seat 11 is fixed to the output end of the lifter 1, a translator 2 is fixed to the mounting seat 11, the lifter 1 is used to drive the translator 2 to rise and fall vertically, and the output end of the translator 2 can move horizontally. In this embodiment, the lifter 1 adopts a linear module, and the translator 2 is a linear driver, which is specifically a ball screw structure in this embodiment; a belt feeding mechanism is fixed to the output end of the translator 2,

[0042] Combination Figure 7The belt feeding mechanism includes a rotary driver 21, a traction assembly 3 and a belt feeding buffer assembly. The rotary driver 21 is installed at the output end of the translator 2. A mounting plate 211 is fixed to the output end of the rotary driver 21. The traction assembly 3 and the buffer belt feeding assembly are installed on the mounting plate 211. In this embodiment, the rotary driver 21 is a servo motor. The rotary driver 21 drives the mounting plate 211 at the output end to rotate through a belt drive.

[0043] The traction assembly 3 is used to pull and convey the packaging belt. The traction assembly 3 includes a driving wheel 31 and a driven wheel 32. At least one of the driving wheel 31 and the driven wheel 32 can move to adjust the distance between the driving wheel 31 and the driven wheel 32. In this embodiment, the driving wheel 31 is rotatably connected to the mounting plate 211. The driving wheel 31 is provided with a servo motor. The servo motor is fixed on the mounting plate 211 and is used to drive the driving wheel 31 to rotate; the driven wheel 32 is installed on a linear drive A33. The linear drive A33 is used to drive the driven wheel 32 away from or close to the driving wheel 31. The linear drive A33 is fixed on the mounting plate 211.

[0044] The traction assembly 3 and the tape buffer assembly are both eccentrically arranged with respect to the output center of the rotary driver 21 (the output center of the present embodiment is also the rotation center of the mounting plate 211). The rotary driver 21 is used to drive the tape buffer assembly to rotate, and the rotating tape buffer assembly is used to change the transmission direction of the packaging tape.

[0045] Combination Figure 8 and Fig. 9 The strapping buffer assembly of the baler includes a guide clamp 4, which can swing. A guide channel is provided on the guide clamp 4. The cross-sectional width of the guide channel gradually decreases from the feed end to the discharge end to facilitate the insertion of the strapping tape into the guide channel and to limit the position of the strapping tape. The swing center of the guide clamp 4 is located at the width center of the guide channel and the swing axis of the guide clamp 4 is perpendicular to the guide channel. Specifically, a support block is fixed on the mounting plate 211, and the guide clamp 4 is rotatably connected to the support block through a swing axis.

[0046] The guide clamp 4 includes a guide portion 41 and a movable plate 42. The guide portion 41 is provided with a guide groove 411. The guide groove 411 is in a U-shaped cross section. The left and right side walls of the guide groove 411 of the U-shaped cross section have different heights. The side wall height close to the mounting plate 211 is higher. The guide portion 41 is located on the inner side relative to the movable plate 42 (that is, the guide portion 41 is closer to the swing center of the guide clamp 4). The swing axis is close to the feeding end of the guide channel. The guide portion 41 is rotatably connected to the support block. A pusher 43 (that is, a pusher) is fixedly installed on the side wall of the guide portion 41 with a higher height. The pusher 43 is installed on the high side wall of the U-shaped section), and the movable plate 42 is installed at the output end of the pusher 43. The pusher 43 is used to drive the movable plate 42 away from or close to the bottom of the guide groove 411. After the movable plate 42 is close to the bottom of the guide groove 411, the guide groove 411 and the movable plate 42 enclose a guide channel. In this embodiment, the pusher 43 adopts a cylinder; after the movable plate 42 is away from the guide groove 411, a space for the strapping tape to freely translate is reserved between the top of the short side wall of the guide groove 411 and the movable plate 42, so as to facilitate the subsequent strapping tape to be detached from the guide clamp 4.

[0047] To ensure that the guide clamp 4 can be reset after swinging, first elastic members 44 are symmetrically installed on both sides of the guide channel of the guide clamp 4, one end of the first elastic member 44 is fixed on the guide clamp 4, and the other end of the first elastic member 44 is fixedly installed on the support block or the mounting plate 211, and the two first elastic members 44 are symmetrically arranged about the swing axis.

[0048] In order to enable the end of the packing tape to be aligned with the tape transition groove 101 on the reel 10 before feeding, a guide seat 45 is connected to the cantilever end of the guide clamp 4. The guide seat 45 is used to cooperate with the adjacent ribs 102 on the reel 10. The guide seat 45 can slide between the adjacent ribs 102 of the reel 10.

[0049] In order to avoid hard contact between the tape feeding device and the reel 10, the guide seat 45 is slidably connected to the guide clamp 4. After sliding, the guide seat 45 can move closer to or away from the guide clamp 4. A second elastic member 46 is installed between the guide seat 45 and the guide clamp 4. The first elastic member 44 and the second elastic member 46 are both springs. The second elastic member 46 is used to give the guide seat 45 a pulling force to move closer to the guide clamp 4.

[0050] In order to reduce the wear of the guide seat 45 and reduce the friction between the guide seat 45 and the rib plate 102 on the reel 10 , wear-resistant plastic blocks 451 are detachably installed on both sides of the guide seat 45 , and the plastic blocks 451 are used to be in contact with the rib plate 102 .

[0051] In order to limit the length of the strapping tape passing through the guide channel, a position monitor 47 is installed on the guide clamp 4. The position monitor 47 is used to monitor whether the strapping tape is transmitted to the set position. In this embodiment, an extension rod 48 is fixedly installed on the guide clamp 4 (a sliding frame 49 is fixed on the extension rod 48, and the guide seat 45 slides on the sliding frame 49. One end of the second elastic member 46 is fixed to the end of the guide seat 45, and the other end is fixed to the sliding frame 49 (the projection of the sliding frame 49 is T-shaped)). The extension rod 48 is opposite to the guide channel. A position monitor 47 is installed on the end of the extension rod 48. The position monitor 47 is a photoelectric sensor. A detection hole is provided on the extension rod 48. The light of the photoelectric sensor can pass through the detection hole. When the strapping tape blocks the detection hole, the photoelectric sensor sends a signal to the controller, thereby controlling the servo motor on the traction assembly 3 to stop rotating after a delay through the controller, ensuring that the extended length of the strapping tape can facilitate the subsequent strapping tape to be placed on the strapping transition groove 101 on the reel 10 after rotating with the rotating driver 21.

[0052] A belt feeding method for a baler comprises the following steps:

[0053] S1. The strapping belt passes through the traction assembly 3 and is inserted into the guide channel.

[0054] S2, start the traction component 3, so that the traction component 3 drives the strapping belt to move along the guide channel, until the strapping belt completely passes through the guide channel and extends out of the guide channel for a certain distance, and then stop the traction of the traction component 3.

[0055] S3, control the rotary driver 21 to drive the output center to rotate, so that the end of the strapping belt rotates synchronously with the guide clamp 4, preparing for the strapping belt to align with the belt passing channel 20.

[0056] S4, control the lifter 1 to start so that the guide clamp 4 is close to the tape-threading transition groove 101 of the reel 10. This step S4 is performed after step S3 or synchronously with S3. During steps S3 and S4, the feeding end of the strapping tape is always in a state where it can be pulled out freely.

[0057] As the guide clamp 4 gradually approaches the strapping transition groove 101, the guide seat 45 on the guide clamp 4 is also gradually inserted between the adjacent ribs 102 of the reel 10, forming a guide for the approaching process of the guide clamp 4, ensuring that the end of the strapping tape extending from the guide clamp 4 can accurately fall into the strapping transition groove 101.

[0058] S5, after the strapping tape falls into the transition groove and contacts the bottom of the transition groove, the rotating driver 21 and the lifter 1 are stopped, and the strapping tape is fed through the traction assembly 3 until the strapping tape is inserted into the tape passing channel 20.

[0059] After the strapping tape completely passes through the tape passage 20 and is reinserted into the strapping buckle by other devices on the strapping machine, in order to ensure the tension of the strapping tape and the subsequent engagement of the strapping buckle, the control translator 2 drives the traction assembly 3 and the guide clamp 4 on the mounting plate 211 to move horizontally away from the strapping tape, reserving space for subsequent operations of the strapping tape.

[0060] This embodiment realizes the automatic feeding and threading of the strapping tape, greatly improves the automation level of the strapping tape and strapping buckle, and helps to improve the packaging efficiency.

[0061] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
