Description

Technical Field

[0001] This invention relates to the field of automatic packaging technology, and more specifically to a feeding device for packaging buckles. Background Technology

[0002] In production, in order to facilitate the storage, transportation, sales, and intermediate processing (such as electroplating and heat treatment) of tubular or strip materials (such as copper tubes, copper strips, aluminum tubes, and aluminum strips), it is often necessary to wind the materials onto a roll. After the materials are wound up, they need to be bundled and packaged in a timely manner.

[0003] In existing technologies, for situations with high packaging requirements, such as bundling and packaging of coiled metal materials (e.g., coiled copper tubes, copper strips, aluminum tubes, aluminum strips, etc.), or because of requirements on packaging strength, or because the coiled metal materials need to be packaged before being sent to an annealing furnace for annealing, copper or steel strips are required as packaging straps, and metal strapping buckles are needed for binding. During packaging, both ends of the packaging strap must pass through the strapping buckle, and one end of the packaging strap needs to be bent after passing through the buckle to prevent the buckle from slipping off. Then, a locking machine is used to press the buckle tight so that it is pressed against the packaging strap. Finally, a cutting machine is used to cut off the excess packaging strap.

[0004] In the current technology, the automation technology for strapping and packaging is mostly found in strapless strapping machines. These machines do not use strapping buckles but instead weld the two ends of the strapping tape together. They use heat to weld the stacked strapping tape together, connecting the two ends of the strapping tape to complete the strapping and packaging. However, for strapping tape, which requires the use of metal strapping buckles, existing automatic strapping machines cannot achieve automatic packaging. Therefore, manual packaging is still the current method.

[0005] However, manual packaging requires people to manually take out the packing buckles each time and then thread the packing straps onto the buckles. This manual operation method has the problems of low work efficiency and increased labor costs. Summary of the Invention

[0006] The present invention aims to provide a feeding device for packing buckles, so as to solve the problem of low efficiency in the prior art where metal packing buckles need to be manually picked up.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A feeding device for packing buckles includes a storage rack and a packing buckle pushing component. The storage rack is provided with a stacking channel for stacking packing buckles. The storage rack is provided with a dropping hole, and the lower end of the stacking channel is connected to the dropping hole. The pushing component includes a pusher and a push block. The pusher is used to drive the push block to move, and the push block is used to push the packing buckles falling from the dropping hole to a set position.

[0009] The principle and advantages of this solution are as follows: Multiple packing buckles can be stacked in the stacking channel of the storage rack. After each packing is completed, the pusher drives the push block to move, pushing the packing buckle that has fallen from the discharge hole to a set position (the set position is the strapping position of the packing buckle to be strapped, also known as the ready position). When used in conjunction with an automatic packing machine, this solution can automatically release the packing buckles. Compared to the existing method of manually retrieving packing buckles each time, this solution enables automatic release of the packing buckles, which improves the degree of automation and thus increases work efficiency.

[0010] In addition, the stacking channel on the storage rack in this solution allows multiple packing clips to be placed in the stacking channel, which integrates the storage and feeding of packing clips and reduces the frequency of adding packing clips.

[0011] Preferably, as an improvement, the push block is provided with a supporting surface and a pushing surface. The supporting surface is located below the material drop hole, and the distance between the supporting surface and the material drop hole is greater than the height of one packing buckle and less than the height of two packing buckles. The pushing surface is located on one side of the supporting surface and is used to push the packing buckle that falls on the supporting surface.

[0012] Beneficial effects: The pusher in this solution moves the pusher block, and the pushing surface on the pusher block pushes the packing buckle that falls from the material drop hole onto the support surface to the standby position (i.e., the set position), realizing the automatic release of the packing buckle. This solution has a simple structure, is easy to control, and has low cost.

[0013] Preferably, as an improvement, the supporting surface is provided with a guide groove, which is used to support the packing buckle so that the packing buckle will not fall off the guide groove during the pushing process, thus ensuring the stability of the packing buckle when it is pushed out.

[0014] Preferably, as an improvement, it also includes a fixedly installed limiting member, which is located above the push block. A receiving space for accommodating a packing buckle is formed between the limiting member and the push block. The limiting member is provided with a stop edge, which is used to limit the travel of the packing buckle.

[0015] Beneficial effect: By setting up this solution, after the pusher pushes out the push block, the packing buckle can move from directly below the material drop hole to abut against the stop edge of the limiting component, thus preventing the packing buckle from being pushed out excessively.

[0016] Preferably, as an improvement, a lower guide member is fixedly connected to the push block, and an upper guide member is fixedly connected to the limiting member. The lower guide member has an L-shaped cross-section, and the upper guide member has an inverted L-shaped cross-section. The lower guide member and the upper guide member form a flared opening, which is used for guiding the buckle when the packaging strap is threaded.

[0017] Beneficial effects: By setting up upper and lower guide components, this solution enables the flared opening formed by the upper and lower guide components to guide the strapping tape that is inserted into the strapping buckle, reducing the requirements for tape feeding on the automatic strapping machine and thus reducing the probability of malfunctions.

[0018] Preferably, as an improvement, it also includes a bending assembly, which includes a bending driver and a bending plate. The bending plate can be located at the discharge end of the packing buckle, and the bending driver is used to drive the bending plate to rotate, thereby bending the packing strap that passes through the packing buckle.

[0019] Beneficial effects: This solution uses a bending driver on the bending assembly to drive the rotation of the bending plate, thereby enabling the bending plate to bend the packing strap that passes through the packing buckle, further improving the level of automation.

[0020] Preferably, as an improvement, the bending component is installed at the output end of the pusher or on a separately controlled forward / backward driver to drive the bending plate away from the set position.

[0021] Beneficial effects: This solution ensures that after the strapping is bent, to prevent the bending plate from affecting the subsequent tightening of the strapping by the locking machine, the bending plate is moved away from the set position by the forward and backward drive, thus ensuring that the bending plate does not affect the subsequent tightening of the strapping and the engagement of the strapping buckle. In addition, when the bending component is installed at the output end of the pusher, it can reduce costs and control difficulty while achieving bending and facilitating the subsequent locking operation of the strapping buckle after bending.

[0022] Preferably, as an improvement, the bending plate is eccentrically positioned relative to the output shaft center of the bending driver.

[0023] Beneficial effects: This solution uses an eccentrically designed bending plate, which makes bending the packing straps easier compared to a non-eccentric design. It also allows the packing straps to bend slowly, preventing them from bending rapidly at the initial contact point with the bending plate, which could lead to excessive stretching on one side and excessive compression on the other, thus damaging the strength of the packing strap at the bend.

[0024] Preferably, as an improvement, the storage rack is detachably connected to a material box, the stacking channel is located on the material box, and the material box is provided with an observation window.

[0025] Beneficial effects: The material tray design allows for quick refilling by replacing the material tray when the strapping clips are used up; and the observation window makes it easy to quickly know the consumption status of the strapping clips. Attached Figure Description

[0041] The following detailed description illustrates the specific implementation method:

[0042] The reference numerals in the accompanying drawings include: storage rack 1, material box 11, stacking channel 111, observation window 112, horizontal quick clamp 12, pusher 2, mounting plate 21, push block 22, support surface 221, pushing surface 222, lower guide 23, limiting component 3, edge guard 31, upper guide 32, bending driver 4, bending plate 41, connecting plate 42, mounting plate 43, packing buckle 10, integrated locking machine 5, tensioning mechanism 51, biting mechanism 52, cutting knife 53, lifting device 6, photoelectric sensor 7, trigger component 71, trigger rod 8, contact block 9.

[0043] Example 1

[0044] Combination Figures 1 to 11 A feeding device for packing buckles includes a storage rack 1 and a packing buckle 10 pushing assembly. The storage rack 1 is fixedly installed, and a material box 11 is detachably connected to the storage rack 1 via a horizontal quick clamp 12 (the horizontal quick clamp 12 is fixed to the storage rack 1, and the storage rack 1 is provided with a U-shaped storage space for the material box 11. The horizontal quick clamp 12 can press the material box 11 against the storage space of the storage rack 1). The material box 11 includes four uprights, and the four uprights are connected at their ends by a connecting structure. The four uprights enclose a vertical stacking channel 111, which is used to stack the packing buckles 10. An observation window 112 is formed between adjacent uprights, which facilitates observation of the use of the packing buckles 10. A material drop hole is opened on the storage rack 1, and the lower end of the stacking channel 111 is connected to the material drop hole.

[0045] The pushing component includes a pusher 2 and a pusher block 22. The pusher 2 is fixedly installed on the storage rack 1. The pusher 2 is used to drive the pusher block 22 to move. In this embodiment, the pusher 2 is a cylinder. The output end of the cylinder is fixed with a mounting plate 21. The pusher block 22 is fixed on the mounting plate 21. The pusher block 22 has a horizontal support surface 221 and a vertically arranged abutting surface 222 integrally formed on it. The support surface 221 is located below the material drop hole. The distance between the support surface 221 and the material drop hole is greater than the height of one packing buckle 10 and less than the height of two packing buckles 10. In this embodiment, the spacing is controlled to be slightly greater than the height of one packing buckle 10, for example, 1-5mm higher than the height of the packing buckle 10. The abutting surface 222 is located on one side of the support surface 221 and is used to push the packing buckle 10 that falls on the support surface 221.

[0046] The bottom of the storage rack 1 is also fixed with a limiting member 3. The limiting member 3 is located above the push block 22. The gap between the limiting member 3 and the supporting surface 221 is used to accommodate a packing buckle 10 (that is, the accommodating space of the packing buckle 10). The limiting member 3 has an integrally formed edge 31. The edge 31 and the pushing surface 222 can be located on both sides of the packing buckle 10. In this embodiment, the edge 31 blocks less than half the height of the packing buckle 10 so as to facilitate viewing the packing buckle 10 from the gap between the push block 22 and the edge 31.

[0047] The stacked strapping buckles 10 fall onto the support surface 221 through the drop hole under gravity. Under the push of the pusher 2, the strapping buckles 10 are pushed from directly below the drop hole to the ready position. To ensure the stability of the strapping buckles 10 during the pushing process, a guide groove is opened on the support surface 221. The guide groove is used to support the strapping buckles 10 and form a guide and constraint on the moving direction of the strapping buckles 10.

[0048] A lower guide 23 is fixed to one end of the push block 22 near the stop edge 31 of the limiting member 3, and an upper guide 32 is fixed to one end of the limiting member 3 near the stop edge 31. The cross-section of the lower guide 23 is L-shaped, and the cross-section of the upper guide 32 is inverted L-shaped. The lower guide 23 and the upper guide 32 form a flared mouth, which is used for guiding the strapping of the packing buckle 10.

[0049] To facilitate the automatic bending of the end section of the strapping tape after the strapping buckle 10 is pushed to the ready position, a bending component is fixedly installed on the mounting plate 21 connected to the output end of the pusher 2. The bending component includes a bending driver 4 and a bending plate 41. The bending driver 4 is fixed on the mounting plate 21, and the bending plate 41 can be located at the discharge end of the strapping buckle 10. The bending driver 4 is used to drive the bending plate 41 to rotate, thereby bending the strapping tape passing through the strapping buckle 10 to the outside of the strapping buckle 10.

[0050] The bending plate 41 is eccentrically positioned relative to the output shaft center of the bending driver 4. Specifically, in order to save space and not affect the movement of the push block 22, an L-shaped connecting plate 42 is fixed on the output disc of the bending driver 4. A mounting plate 43 is welded to the free end of the L-shaped connecting plate 42. The bending plate 41 is fixed on the mounting plate 43, which is located on one side of the strapping (the mounting plate 43 is located on the side when the strapping buckle 10 is in the standby position) to guide the strapping after continuous threading and feeding.

[0051] An automatic feeding method for packaging buckles includes the following steps:

[0052] S1. In the initial state, the receiving surface of push block 22 is located directly below the material discharge hole.

[0053] S2. When the strapping buckle 10 needs to be threaded and packaged, the pusher 2 moves the bending component and the pusher block 22 horizontally, so that the strapping buckle 10 moves from directly below the drop hole to the ready position; at this time, the bending plate 41 of the bending component is located below the threading hole of the strapping buckle 10 (to facilitate the subsequent threading of the strapping tape), that is... Figure 8 As shown.

[0054] S3. The strapping strap passes through the strapping buckle 10 in the ready position. Before the strapping strap wraps back to be inserted into the strapping buckle 10 again, the bending driver 4 is controlled to drive the bending plate 41 to rotate upward (to achieve the following). Figure 9 As shown), this provides space for the strapping to pass through the strapping buckle 10 again. After the section of the strapping that needs to be bent is below the bending plate 41, the bending driver 4 is activated again, causing the bending driver 4 to drive the bending plate 41 to swing downward, thereby completing the end bending of the strapping (as shown). Figure 10 (As shown).

[0055] In step S3, the flared opening on the feeding device allows the strapping to be smoothly inserted into the strapping buckle 10 at the waiting position, improving the efficiency of strapping.

[0056] In this step, the bending plate 41 is eccentrically positioned relative to the bending driver 4, which makes it easier to bend the packing strap with the bending plate 41. At the same time, it also facilitates the slow bending of the packing strap, avoiding the problem of the packing strap bending rapidly at the initial contact position with the bending plate 41, which would cause one side of the packing strap to be overstretched and the other side to be overcompressed during bending, thus damaging the strength of the packing strap at the bend.

[0057] S4. After bending is completed, the pusher 2 drives the bending component and the pusher block 22 to retract, so that the bending plate 41 and the pusher block 22 move completely to the side of the packing buckle 10 with the packing strap on, so as to facilitate the subsequent clamping (or fastening) of the packing buckle 10.

[0058] In addition, after the push block 22 retracts, the packing buckle 10 stacked at the bottom falls into the receiving surface of the push block 22, preparing for the next material feeding.

[0059] Compared with the prior art, this embodiment can realize the automatic release of the packing buckle 10, facilitate the threading of the packing strap, and also bend the end of the packing strap after the packing buckle 10 is threaded, which greatly improves the degree of automation and helps to promote the automatic packing technology of metal packing buckle 10 and packing strap.

[0060] Example 2

[0061] An application of a packing buckle dispensing device, used in a packing machine, for automatically dispensing the packing buckles 10 required in the packing process.

[0062] Example 3

[0063] Combination Figures 12 to 15 A packing buckle release and snapping device includes the packing buckle 10 release device of Embodiment 1, and also includes an integrated snap-locking machine 5. The integrated snap-locking machine 5 is installed at the output end of the lifting device 6 (the output end of the lifting device 6 is referred to as the lifting seat in this embodiment) so that the integrated snap-locking machine 5 can be lifted and lowered under the drive of the lifting device 6, eliminating the need for manual hand packing and reducing labor intensity.

[0064] Specifically, the integrated buckle-locking machine 5 integrates the functions of tensioning the strapping, engaging the buckle 10, and cutting the strapping. The integrated buckle-locking machine 5 is a manual strapping machine of the prior art. That is, the integrated buckle-locking machine 5 includes a tensioning mechanism 51, an engaging mechanism 52, and a cutting knife 53. The tensioning mechanism 51 is used to drive the strapping to move, so as to realize the forward feeding or retraction of the strapping. The engaging mechanism 52 is used to engage the buckle 10. After the buckle 10 is engaged or at the same time as engagement, the cutting knife 53 cuts the strapping.

[0065] The tensioning mechanism 51 includes a tensioning driver and a forward / backward wheel. The tensioning driver is used to drive the forward / backward wheel to rotate forward or backward. A strapping plate is fixed on the lifting seat. The strapping plate is located directly below the forward / backward wheel. After the forward / backward wheel rotates, it clamps the packing strap between the strapping plate and the forward / backward wheel for transmission.

[0066] The biting mechanism 52 and the cutting blade 53 in this embodiment are as shown in the linkage mechanism and cutting blade 53 disclosed in patent publication number CN106347735A.

[0067] To monitor the distance between the integrated locking machine 5 and the material to be packaged, and to prevent the integrated locking machine 5 from getting too close to the material and damaging it, a monitor is installed at the output end of the lifting device 6. The monitor is used to stop the lifting device 6 when the distance between the integrated locking machine 5 and the material to be packaged reaches a set value. Specifically, the monitor includes a photoelectric sensor 7 and a trigger 71. The photoelectric sensor 7 is used to control the lifting device 6 to stop working. The photoelectric sensor 7 is fixed at the output end of the lifting device 6 (i.e., on the lifting base). The trigger 71 is fixedly installed on the top of the trigger rod 8. The trigger rod 8 is vertically slidably connected to the lifting base. A contact block 9 is fixed at the bottom end of the trigger rod 8. The contact block 9 can be pushed by the material to be packaged, and the bottom end of the contact block 9 can be located on the outside of the integrated locking machine 5.

[0068] In this embodiment, when the lifting device 6 moves the integrated locking machine 5 closer to the material to be packaged, the end of the contact block 9 is located on the outside of the integrated locking machine 5. As a result, when the integrated locking machine 5 moves closer to the material to be packaged under the action of the lifting device 6, the contact block 9 is the first to contact the material to be packaged. As the lifting device 6 continues to work, the locking machine gradually moves closer to the material to be packaged. During the approach process, the trigger 71 also gradually moves closer to the photoelectric sensor 7 until the distance between the integrated locking machine 5 and the material to be packaged reaches the set value. The photoelectric sensor 7 is sensed by the trigger 71 and the lifting device 6 is stopped.

[0069] This embodiment makes it easier to release the strapping buckle 10. After the strapping strap is threaded through, the integrated locking machine 5 can quickly tighten the strapping strap, engage the strapping buckle 10, and cut off the excess strapping strap, further improving the level of automation.

[0070] The above descriptions are merely embodiments of the present invention, and common knowledge such as specific technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
