Abstract

This application discloses a precise guiding mechanism for strapping tape and a strapping machine. The precise guiding mechanism includes a first driving member and two sets of limiting components. Each limiting component includes a base, a second driving member, a transverse sliding seat, and a limiting member. A guiding channel for the strapping tape to pass through is formed between the two sets of limiting components. The transverse sliding seat is installed at one end of the base near the pallet and can reciprocate along a first direction. The second driving member is connected to the transverse sliding seat and drives its reciprocating movement. The limiting member can float along a second direction and is located on the side near the pallet. The first driving member moves the two sets of limiting components toward the pallet, causing the limiting member to abut against a limiting groove on the pallet. Subsequently, the second driving member drives the transverse sliding seat toward the limiting groove, causing the limiting member to engage in the groove. Thus, the strapping tape in the guiding channel is gathered between the limiting members, ensuring that the strapping position is within the limiting groove, improving the efficiency and accuracy of strapping.

Description

Technical Field

[0001] This application relates to the field of material packaging technology, and in particular to a strapping tape precision guiding mechanism and strapping machine. Background Technology

[0002] With the continuous improvement of the technical requirements for material packaging, when bundling some materials, it is necessary to accurately tie the strapping tape in the preset position. In order to facilitate bundling, a limiting groove is usually opened on the pallet carrying the material. When bundling, the strapping tape is required to be tightened and fixed in the limiting groove.

[0003] Currently, when existing strapping machines strap the material, although the strapping channel can move to the position of the corresponding limiting groove, the strapping tape is in a loose state before tightening and fixing. During the process of the strapping machine head rapidly tightening the strapping tape, the strapping tape will shake, causing the strapping tape to deviate from the corresponding limiting groove on the pallet, making it impossible to perform precise strapping. Utility Model Content

[0004] The purpose of this application is to provide a precise guide mechanism for strapping tape, so as to solve the problem that existing strapping machines cannot achieve precise strapping because the strapping tape shakes when tightening. In addition, this application also provides a strapping machine including the precise guide mechanism for strapping tape.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] A precise guiding mechanism for cable ties includes a first driving component and two sets of limiting components, wherein:

[0007] Two sets of limiting components are spaced apart along a first direction. Each set of limiting components includes a base, a second driving member, a transverse seat, and a limiting member. A guide channel for the strapping tape to pass through is formed between the bases of the two sets of limiting components. The driving end of the first driving member is connected to the bases of the two sets of limiting components. The first driving member is configured to drive the bases of the two sets of limiting components to move synchronously closer to or further away from the pallet of the material to be strapped along a second direction. The pallet is provided with a limiting groove for accommodating the strapping tape.

[0008] The transverse sliding seat is reciprocally mounted on one end of the base near the pallet in a first direction. The driving end of the second driving member is connected to the transverse sliding seat. The second driving member is configured to drive the transverse sliding seat to reciprocate in the first direction. The limiting member is floatingly mounted on the transverse sliding seat in a second direction and is located on the side near the pallet.

[0009] The first driving component drives the two sets of limiting components to move closer to the pallet, so that the limiting components of the two sets of limiting components float and abut against the limiting grooves on both sides in the first direction. The second driving component of the two sets of limiting components drives the transverse seat to move closer to the limiting grooves along the first direction, so as to drive the limiting components of the two sets of limiting components to be engaged in the limiting grooves, so that the strapping in the guide channel is pulled up between the limiting components of the two sets of limiting components, so as to ensure that the strapping position is located in the limiting grooves.

[0010] Optionally, a floating component is provided between the limiting component and the transverse seat. The floating component includes a floating block and an elastic element. The floating block is floatingly mounted on the transverse seat through the elastic element. The first end of the elastic element abuts against the transverse seat, and the second end of the elastic element abuts against the floating block.

[0011] Optionally, the floating assembly also includes two guide members. Two guide holes are spaced apart along the height direction on the transverse seat. Each guide member corresponds to one guide hole, and the guide members are reciprocally inserted into the guide holes along the second direction.

[0012] Optionally, the limiting component includes a guide plate and a rolling element. The rolling element is rotatably mounted on the guide plate, and the guide plate is detachably mounted on the floating block. The guide plate is configured to guide the strapping into the space between the guide plates of the two limiting components. The first driving component drives the bases of the two limiting components to move synchronously closer to the pallet, so that the rolling elements of the two limiting components abut against the limiting grooves on both sides in the first direction.

[0013] Optionally, a pin is vertically provided at one end of the guide plate near the pallet, and the rolling element includes at least one roller, which is rotatably mounted vertically on the pin.

[0014] Optionally, a first guide portion is provided at the bottom of the guide plate, and a first inclined surface is provided on the first guide portion. The first inclined surface is inclined downward in a direction away from the guide channel, and the first inclined surface is configured to guide the strapping in the guide channel at the bottom of the guide plate.

[0015] Optionally, a second guide portion is provided on the side of the guide plate away from the pallet, and a second inclined surface is provided on the second guide portion. The second inclined surface is inclined in a direction away from the outside of the guide channel, and the second inclined surface is configured to guide the strapping in the guide channel on the side of the guide plate away from the pallet.

[0016] A strapping machine includes a gantry frame, a strapping mechanism, and two strapping tape precision guiding mechanisms, wherein:

[0017] The bottom of the gantry is equipped with a bundling station for receiving materials to be bundled and pallets. The materials to be bundled are placed on the pallets, and the bottom of the pallets has two limiting grooves on both sides in the second direction.

[0018] Two precise guide mechanisms for strapping are respectively set on both sides of the strapping station in the second direction. The precise guide mechanisms for strapping are configured to guide the strapping on the corresponding side into the corresponding limiting groove.

[0019] The strapping mechanism is mounted on the gantry and is configured to work in conjunction with two strapping tape precision guide mechanisms to precisely strap the materials to be strapped and the pallets at the strapping station.

[0020] Compared with the prior art, the strapping tape precision guiding mechanism provided in this application has the following advantages:

[0021] 1) Through the cooperation of the first driving component and two sets of limiting components, the strapping can move smoothly in the precise guide channel to ensure that the strapping can enter the preset limiting groove correctly and stably. This not only improves the efficiency and accuracy of strapping, but also has a simple structure and is easy to operate.

[0022] 2) By setting vertical pins and rotating rollers on the guide plate, the friction between the guide plate and the pallet is reduced, which not only extends the service life of the guide plate, but also facilitates the pins to quickly enter the limiting groove, thus improving the efficiency and accuracy of binding.

[0023] 3) By setting a floating component between the limiting component and the transverse seat, the limiting component can adjust itself when subjected to slight external impact or positional deviation, which also avoids misalignment of the guide due to minor equipment errors and improves the fault tolerance of the equipment.

[0030] Please see Figures 1 to 5 As shown in the embodiment of this application, a precise guiding mechanism 70 for cable ties includes a first driving member 10 and two sets of limiting components 20, wherein:

[0031] Two sets of limiting components 20 along the first direction ( Figure 1 The two sets of limiting components 20 are spaced apart in the middle X direction. Each set of limiting components 20 includes a base 21, a second driving member 22, a transverse sliding seat 23, and a limiting member 24. A guide channel 30 for the strapping 40 to pass through is formed between the bases 21 of the two sets of limiting components 20. The driving end of the first driving member 10 is connected to the bases 21 of the two sets of limiting components 20. The first driving member 10 is configured to drive the bases 21 of the two sets of limiting components 20 synchronously along the second direction (X direction). Figure 1 The pallet 50 (in the Y direction) is close to or far from the material to be bundled, and the pallet 50 is provided with a limiting groove 51 for accommodating the bundling strap 40;

[0032] The transverse sliding seat 23 is reciprocally mounted on one end of the base 21 near the pallet 50 in a first direction. The driving end of the second driving member 22 is connected to the transverse sliding seat 23. The second driving member 22 is configured to drive the transverse sliding seat 23 to reciprocate in the first direction. The limiting member 24 is floatingly mounted on the transverse sliding seat 23 in a second direction and is located on one side near the pallet 50.

[0033] The first driving member 10 drives the two sets of limiting components 20 to move closer to the pallet 50, so that the limiting members 24 of the two sets of limiting components float and abut against the limiting groove 51 on both sides in the first direction. The second driving member 22 of the two sets of limiting components 20 drives the transverse seat 23 to move closer to the limiting groove 51 along the first direction, so as to drive the limiting members 24 of the two sets of limiting components 20 to be inserted into the limiting groove 51, so that the strapping 40 in the guide channel 30 is pulled up between the limiting members 24 of the two sets of limiting components 20, so as to ensure that the strapping position of the strapping 40 is located in the limiting groove 51.

[0034] Specifically, the limiting component 20 is fixedly connected to a baffle 26, and a buffer pad 260 is provided on the baffle 26. When the first driving component 10 drives the limiting component 20 to move toward the pallet 50, the buffer pad 260 on the baffle 26 first comes into contact with the material to be bundled in order to maintain the stability of the material to be bundled.

[0035] Through the cooperation of the first driving component 10 and the two sets of limiting components 20, the strapping 40 can move smoothly in the precise guide channel 30, so as to ensure that the strapping 40 can enter the preset limiting groove 51 correctly and stably. This not only improves the efficiency and accuracy of strapping, but also has a simple structure and is easy to operate.

[0036] In one embodiment, a floating component 25 is provided between the limiting member 24 and the transverse seat 23. The floating component 25 includes a floating block 250 and an elastic member 251. The floating block 250 is floatingly mounted on the transverse seat 23 through the elastic member 251. The first end of the elastic member 251 abuts against the transverse seat 23, and the second end of the elastic member 251 abuts against the floating block 250.

[0037] Specifically, the elastic element 251 is configured as a spring.

[0038] By setting a floating component 25 between the limiting component 24 and the transverse seat 23, a floating force is provided for the limiting component 24 when it comes into contact with the material, avoiding hard contact between the limiting component 24 and the material, and also avoiding misalignment of the guide due to minor errors in the equipment, thereby improving the fault tolerance of the equipment.

[0039] In one embodiment, the floating component 25 further includes two guide members 252. Two guide holes 230 are spaced apart along the height direction on the transverse shift seat 23. Each guide member 252 corresponds to one guide hole 230. The guide member 252 is reciprocally inserted into the guide hole 230 along the second direction.

[0040] The cooperation between the guide 252 and the guide hole 230 not only enables the floating block 250 to slide smoothly along the set direction, ensuring the accuracy of the movement direction, but also reduces the coefficient of friction during the movement, reduces the wear of equipment parts, and extends the service life of the equipment.

[0041] In one embodiment, the limiting member 24 includes a guide plate 240 and a rolling member 241. The rolling member 241 is rotatably mounted on the guide plate 240. The guide plate 240 is detachably mounted on the floating block 250. The guide plate 240 is configured to guide the strapping 40 into the space between the guide plates 240 of the two sets of limiting components 20. The first driving member 10 drives the bases 21 of the two sets of limiting components 20 to move synchronously closer to the pallet 50, so that the rolling members 241 of the two sets of limiting components 20 abut against the two sides of the limiting groove 51 in the first direction.

[0042] The cooperation between the guide plate 240 and the rolling element 241 improves the guiding effect of the strapping 40 into the limiting component 20, ensures the smoothness of the strapping 40 during the strapping process, and reduces the risk of the strapping 40 deviating.

[0043] In one embodiment, a pin 242 is vertically disposed at one end of the guide plate 240 near the pallet 50, and the rolling element 241 includes at least one roller, which is rotatably mounted vertically on the pin.

[0044] The vertical pin 242 and the rotating roller work together to reduce the friction between the guide plate 240 and the pallet 50, which not only extends the service life of the guide plate 240, but also makes it easier for the pin 242 to quickly enter the limiting groove 51, thus improving the efficiency and accuracy of the binding.

[0045] In one embodiment, a first guide portion is provided at the bottom of the guide plate 240, and a first inclined surface 2401 is provided on the first guide portion. The first inclined surface 2401 is inclined downward in a direction away from the guide channel 30. The first inclined surface 2401 is configured to guide the strapping 40 in the guide channel 30 at the bottom of the guide plate 240.

[0046] By setting an inclined first slope 2401 on the first guide section, it is not only convenient for the strapping 40 to smoothly enter the channel and improve the efficiency of strapping work, but also reduces the friction between the strapping 40 and the guide component, thereby reducing wear and extending the service life of the strapping 40.

[0047] In one embodiment, a second guide portion is provided on the side of the guide plate 240 away from the pallet 50, and a second inclined surface 2402 is provided on the second guide portion. The second inclined surface is inclined in a direction away from the outside of the guide channel 30, and the second inclined surface 2402 is configured to guide the strapping 40 in the guide channel 30 on the side of the guide plate 240 away from the pallet 50.

[0048] By setting an inclined second slope 2402 on the second guide section, it is not only convenient to effectively guide the strapping 40 smoothly into the guide channel 30, reducing the misalignment or jamming of the strapping 40 and improving the strapping efficiency, but also reduces the friction between the strapping 40 and the guide plate 240 when tightening, thus improving the safety and stability of the strapping process.

[0049] A strapping machine includes a gantry frame 61, a strapping mechanism, and two strapping tape precision guiding mechanisms 70, wherein:

[0050] The bottom of the gantry frame 61 is provided with a bundling station for receiving the materials to be bundled and the pallet 50. The materials to be bundled are placed on the pallet 50, and the bottom of the pallet 50 has two limiting grooves 51 on both sides in the second direction.

[0051] Two strapping tape precision guiding mechanisms 70 are respectively set on both sides of the strapping station in the first direction. The strapping tape precision guiding mechanism 70 is configured to guide the strapping tape 40 on the corresponding side into the corresponding limiting groove 51.

[0052] The strapping mechanism is mounted on the gantry 61 and is configured to work with the two strapping straps 40 and the precision guide mechanism 70 to precisely strap the materials to be strapped and the pallet 50 at the strapping station.

[0053] Specifically, the strapping mechanism includes a third drive unit 62, a lifting seat 63, a strapping head 64, a top strapper 65, a piercing drive unit 66, a movable strapper 67, and two side strappers 68, wherein:

[0054] The lifting seat 63 is flexibly mounted on the gantry 61. The strapping head 64 is mounted on the lifting seat. The drive end of the third drive unit 62 is connected to the lifting seat 63. The third drive unit 62 is used to drive the lifting seat 63 to lift and lower so as to synchronously drive the strapping head 64 to move closer to or away from the strapping station in the vertical direction.

[0055] The top cable tie 65 is mounted on the lifting platform, and the two side cable ties 68 are mounted on the two inner sides of the gantry 61. The cable tie drive 66 drives the movable cable tie 67 to approach the bottom of the two side cable ties 68 to close the bottom of the cable tie channel.

[0056] The strapping head 64 is used to release the strapping tape 40 into the strapping channel. The strapping head 64 is also used to tighten, weld and cut the strapping tape 40 in the strapping channel to fix the material on the pallet 50.

[0057] The working principle of the above-mentioned strapping machine is as follows:

[0058] S1, The external conveying mechanism transports the pallet 50 and the materials on the pallet 50 to the bundling station;

[0059] S2, the arrow-piercing drive 66 drives the movable threader 67 to approach the bottom of the two lateral threaders 68, so that the movable threader 67 passes through the bottom of the pallet 50 and closes the bottom of the entire cable tie channel. The strapping head 64 releases the strapping 40 into the cable tie channel so that the strapping 40 forms a closed loop in the cable tie channel.

[0060] S2, the first driving member 10 corresponding to the two sets of strapping tape precision guiding mechanisms 70 drives the corresponding two sets of limiting components 20 to approach the pallet 50, so that the buffer pad 260 abuts against the receiving strapping material and the limiting member 24 floats against the two sides of the limiting groove 51 extending in the first direction.

[0061] S3, the second driving member 22 drives the transverse sliding seat 23 to move closer to the limiting groove 51 along the first direction, so as to synchronously drive the limiting member 24 to move closer to the limiting groove 51 along the first direction until the pin 242 enters the limiting groove 51 through the elastic force provided by the floating member 25.

[0062] S5, when the strapping head 64 tightens the strapping tape 40, the third drive component 62 drives the lifting seat 63 to descend, so as to synchronously drive the strapping head 64 to approach the material, and the strapping tape 40 close to the pallet 50 enters the limiting groove 51 through the guide channel 30.

[0063] S6, when the strapping head 64 tightens the strapping tape 40 in the strapping tape channel to a preset degree, it performs welding and tape cutting to achieve the binding of materials to the pallet 50.

[0064] The above embodiments merely illustrate the basic principles and characteristics of this application. This application is not limited to the above examples. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed. The scope of protection of this application is defined by the appended claims and their equivalents.
