Description

Technical Field

[0001] The utility model discloses a guiding mechanism for a fine-winding yarn and a bobbin conveying interface device, belonging to the technical field of fine-winding spinning. Background Art

[0002] The fine spinning process is from the drop of fine yarn to the exchange of cop yarn and bobbin, the collection of cop yarn, and centralized transportation to the winder for winding. Then the bobbin with finished yarn is transported to the spinning frame for the exchange of cop yarn / bobbin, and the cycle is repeated to complete the process of fine yarn cop yarn to bobbin.

[0003] The cop and bobbin conveying interface device is arranged between the cop and bobbin conveying system of the automatic doffing spinning frame and the cop and bobbin conveying system of the automatic winder. The cop and bobbin tray conveying system mainly adopts a steel belt and a tray bracket structure. Under the action of the steel belt driving mechanism, the tray bracket moves along the conveying guide rail, and the pallet with full yarn bobbins is separated from the tray bracket and sent to the conveying system of the automatic winder. Then the pallet with the bobbins is sent to the tray bracket and enters the tray conveying system of the collective doffing spinning frame, so as to achieve the purpose of exchanging and recycling full yarn bobbins and empty bobbins.

[0004] Although the existing interface device uses an input guide plate and an output limit plate to guide and limit the passing pallet, the input belt / chain cannot extend between the two pallet brackets. Therefore, there is still a certain distance when the bobbin detaches from the pallet conveying system and enters the interface device. The output limit plate is connected to the guide plate by a spring. When the pallet passes and contacts the output limit plate, the output limit plate will press against one side of the pallet positioning column. The elastic guide easily causes the pallet to detach from the pallet bracket and enter the interface device. The consistency is poor, which is easy to cause a jam at the interface. Similarly, when the bobbin enters the pallet conveying system from the interface device, there is still a certain distance when entering the pallet conveying system. The input limit plate only plays a guiding role. Therefore, after the pallet detaches from the input belt / chain, the pallet has no external thrust, and the position of the pallet entering between the two pallet brackets is unstable, which actually causes the consistency of the pallet entering the pallet bracket to be low, and prolongs the time for the pallet to enter the pallet bracket. The input guide plate and the output limit plate both guide and limit the lower part of the bobbin, and the stability is poor during the pallet conveying process. Summary of the invention

[0005] The utility model aims to provide a guiding mechanism for a fine-winding bobbin and a bobbin conveying interface device which has a reasonable structure and can improve the consistency and reliability in the tray conveying process.

[0006] The utility model is a technical solution to achieve the above-mentioned purpose: a guide mechanism for a thin-winding bobbin and a bobbin conveying interface device, characterized in that it includes an interface seat assembly and a tray input and output guide assembly;

[0007] The interface seat assembly is used for the pallet to run along the interface channel, and includes a guide plate, a support plate and an interface base connected in sequence from top to bottom; a space for the pallet base to pass through and a height limit is provided between the guide plate and the support plate, and an interface channel is provided on the guide plate and the support plate, and the interface channel includes an interface input channel and an interface output channel;

[0008] The tray input and output guide assembly is used to guide and limit the input and output trays, including a guide limit plate, an input guide plate and an output guide plate installed on the interface seat assembly; one end of the guide limit plate extends into the cavity of the tray holder, and the guide limit plate has an inner input guide surface on the input side, and the outer input guide surface on the input guide plate and the inner input guide surface form an input transition channel connected to the interface input channel, and the outer input guide surface is used to push the base of the conveyed pallet toward one side of the tray holder to clamp and position the pallet; the guide limit plate has an inner output guide surface on the output side, and the outer output guide surface on the output guide plate and the inner output guide surface form an output transition channel connected to the interface output channel, and the inner output guide surface is used to push out the base of the conveyed pallet, so that the tray holder releases the positioning and clamping of the pallet.

[0009] The utility model forms a corresponding input transition channel and an output transition channel through a guide limit plate and a corresponding input guide plate and an output guide plate. When entering the input transition channel, the input guide plate pushes the conveyed pallet base toward one side of the pallet bracket, so that the pallet fork on the pallet bracket positions and clamps the pallet positioning column. At the same time, the inner output guide surface on the guide limit plate is used to push the conveyed pallet base out, so that the pallet bracket releases the positioning and clamping of the pallet. Therefore, no matter in the input and output process of the pallet, the problem of the pallet jamming during the conveying process caused by the spacing between the two tracks when changing tracks can be overcome. During the conveying and exchanging process of the pallet, the guide limit plate, the input guide plate and the output guide plate all guide and apply thrust to the pallet base, which greatly improves the consistency of the pallet when passing through. The pallet can smoothly enter the conveyor belt / chain and be sent to the conveying system of the automatic winding machine. At the same time, the pallet can also smoothly enter the pallet conveying system of the collective yarn dropping spinning machine from the conveyor belt / chain, thereby improving the reliability of the pallet conveying.

DETAILED DESCRIPTION

[0019] See Figures 1 to 7 As shown, the utility model is a guide mechanism for a fine winding and bobbin conveying interface device, comprising an interface seat assembly and a tray input and output guide assembly. The guide mechanism of the utility model is used to pull out a tray 16 in a tray conveying system of an automatic doffing spinning frame from a tray bracket 17, and deliver it to the conveying system of the automatic winding machine through an interface output channel 10, and at the same time, the tray 16 in the conveying system of the automatic winding machine is pushed into the tray bracket 17 in the tray conveying system of the automatic doffing spinning frame through an interface input channel 7.

[0020] See Figures 1 to 3As shown, the interface seat assembly of the utility model is used for a pallet 16 to run along an interface channel, and includes a guide plate 1, a support plate 2 and an interface base 3 connected in sequence from top to bottom, the interface base 3 is installed between the automatic yarn dropping spinning machine and the automatic winding machine, and a space for the pallet base to pass through and the height limit is provided between the guide plate 1 and the support plate 2. When the pallet 16 passes through the interface channel, the support plate 2 plays a role in limiting the pallet 16. The guide plate 1 and the support plate 2 are provided with an interface channel, and the interface channel includes an interface input channel 7 and an interface output channel 10. The pallet 16 in the interface input channel 7 passes through the input transition channel and is pushed into the pallet bracket 17, and the pallet 10 in the output transition channel is pulled out and enters the interface output channel 10 and is sent to the conveying system of the automatic winding machine.

[0021] See Figures 1 to 3 As shown, a fixing column 4 is provided between the guide plate 1 and the support plate 2 of the interface seat assembly of the utility model, and between the support plate 2 and the interface base 3. The fixing column 4 can be multi-stepped and can adopt a structure with a shoulder and a sleeve. The fastener passes through the guide plate 1 and is connected to the fixing column 4, and the guide plate 1, the support plate 2 and the interface base 3 are connected. The interface base 3 is equipped with height-adjustable supporting feet, and the side panels of the interface base 3 are connected to the base of the automatic yarn dropping spinning machine through fasteners.

[0022] See Figures 1 to 3 As shown, the interface input channel 7 on the guide plate 1 and the support plate 2 of the interface seat assembly of the utility model is a straight channel, and the interface output channel 10 is a curved channel or a straight channel with staggered ends. The interface input channel 7 is located on one side of the driving wheel 18 or the driven wheel 15. Figures 1 to 3 The interface input channel 7 shown is a straight channel and is located on one side of the driving wheel 18, while the interface output channel 10 is a curved channel with staggered ends and passing through the straight channel. Figure 7 As shown, the interface output channel 10 of the utility model is a straight channel and is located on one side of the driven wheel 15. When the pallet 16 passes through the input transition channel, it is pushed into the pallet fork of the pallet holder 17 by the action of the outer input guide surface 6-1 on the input guide plate 6, so that the pallet 16 is accurately clamped and positioned by the pallet fork during the operation of the pallet holder 17. When the steel belt drives the pallet holder 17 to run to the output side, the pallet base in the pallet fork is pushed out and separated from the pallet holder 17 and enters the interface output channel 10 under the action of the guide limit plate 5 in the output transition channel.

[0023] See Figures 1 to 3As shown, a tray belt / chain conveying assembly is installed on the interface seat assembly of the utility model, and a tray 16 is conveyed by the conveyor belt / chain. The conveyor belt / chain is installed on multiple interface guide wheels 8 and an interface drive wheel 14. The interface motor 9 is installed on the interface base 3. The output side of the interface motor 9 is connected to the interface drive wheel 14. The conveyor belt / chain is used to support the tray base and passes through the interface input channel 7 and the interface output channel 10 during operation. When the conveyor belt / chain runs along the track, the conveyor belt / chain passes through the interface input channel 7 and the interface output channel 10 to respectively deliver the tray 16 to the conveying track of the tray conveying system of the corresponding automatic yarn dropping spinning machine and the conveying track of the conveying system of the automatic winding machine, so as to realize the exchange of the tube yarn and the bobbin.

[0024] See Figure 2 , 3 As shown, in order to better enable the pallet 16 to pass through the interface input channel 7 and the interface output channel 10 smoothly, the guide plate 1 is provided with upper input guide plates 126 for limiting the pallet base on both sides of the input of the interface input channel 7, and the guide plate 1 is provided with upper output guide plates 11 for limiting the pallet base on both sides of the output of the interface output channel 10 of the pallet 16. Therefore, the movable gap between the pallet base through the interface input channel 7 and the interface output channel 10 can be reduced, ensuring that the friction between the conveyor belt / chain and the pallet base remains unchanged, so that the pallet 16 can pass through the exchange position more stably.

[0025] See Figures 1 to 4 As shown, the tray input and output guide assembly of the utility model is used to guide and limit the input and output trays 16, including a guide limit plate 5, an input guide plate 6 and an output guide plate installed on the interface seat assembly. Figures 1 to 7 As shown, one end of the guide limit plate 5 of the utility model extends into the cavity of the pallet support 17, and the guide limit plate 5 has an inner input guide surface 5-22 on the input side. The outer input guide surface 6-1 on the input guide plate 6 and the inner input guide surface 5-22 form an input transition channel that communicates with the interface input channel 7. The outer input guide surface 6-1 on the input guide plate 6 is used to push the conveyed pallet base toward the side of the pallet support 17 to clamp and position the pallet, and the pallet fork on the pallet support 17 positions and clamps the pallet positioning column. Figures 1 to 4 As shown, the guide limit plate 5 of the utility model has an inner output guide surface 5-21 on the output side, and the outer output guide surface 13-1 on the output guide plate 13 and the inner output guide surface 5-21 form an output transition channel connected to the interface output channel 10. The inner output guide surface 5-21 is used to push out the base of the conveyed pallet, so that the pallet fork releases the positioning and clamping of the pallet positioning column. Similarly, when the pallet bracket 17 is in operation, the pallet fork on the pallet bracket 17 gives a thrust to the pallet 16, so that the pallet 16 can smoothly detach from the pallet fork and enter the interface output channel 10 from the output transition channel under the action of the inner output guide surface 5-21.

[0026] See Figure 4 , 5 As shown, the guide limit plate 5 of the utility model includes a connecting seat 5-1 and a guide seat 5-2. The connecting seat 5-1 is installed on the interface base 3 by fasteners. The inner input guide surface 5-22 of the guide seat 5-2 extends into the cavity of the pallet bracket 17, including a limit transition plane 5-22-1 and a smooth transition outer inclined surface 5-22-2. The angle α between the outer inclined surface 5-22-2 and the plane of the interface input channel 7 is ≤30°. If the angle α is between 20 and 28°, the pallet base passing through is guided and the pallet positioning column is pressed into the pallet fork opening and positioned and clamped under the joint action of the output guide plate 13. Figure 4 , 5 As shown, the inner output guide surface 5-21 of the guide seat 5-2 of the utility model extends into the cavity of the tray bracket 17, and the inner output guide surface 5-21 includes an inner arc surface or an inner inclined surface. The inner arc surface is located on the upper part of the tray conveying track of the automatic doffing spinning machine. When the inner output guide surface 5-21 is an arc guide surface, the radius of the inner arc surface is more than 3 times the radius of the tray base, such as the radius of the inner arc surface is 3.4 times the radius of the tray base. Figure 7 As shown, the inner output guide surface 5-21 of the guide seat 5-2 of the utility model is an inner bevel, which extends into the cavity of the tray bracket 17, and is located outside the driven wheel 15 or the driving wheel 18. The angle δ between the inner bevel and the output channel plane is ≤20°. If the angle δ is between 10 and 18°, the wall thickness of the inner output guide surface 5-21 of the utility model is less than the wall thickness of the main body. The guide limit plate 5 of the utility model can be as follows Figures 1 to 5 The overall structure shown is Figure 6 , 7 As shown, the guide limit plate 5 of the utility model is a split structure split from the middle and can be set according to needs.

[0027] See Figures 3 to 5 As shown, the outer input guide surface 6-1 on the input guide plate 6 of the utility model is an outer input guide inclined surface, and the angle β between the outer input guide inclined surface and the plane of the interface input channel 7 is ≤45°. If the angle β is between 30 and 40°, the outer input guide inclined surface and the inner input guide surface 5-22 are jointly limited, so that the pallet 16 can smoothly pass through the input transition channel, and the pallet 16 is pushed into the pallet fork of the pallet bracket 17 and clamped in place. Figure 6 As shown, the outer input guide surface 6-1 on the input guide plate 6 of the utility model can also be an outer input guide arc surface, and the arc radius of the outer input guide arc surface is larger than the radius of the pallet base. When the pallet bracket 17 moves, the outer input guide arc surface and the inner input guide surface 5-22 are jointly limited to allow the pallet 16 to pass through the input transition channel smoothly, and the pallet 16 is pushed into the pallet fork of the pallet bracket 17 and clamped in place.

[0028] See Figure 3 , 5 As shown in FIG. 6 , the output guide surface on the output guide plate 13 of the utility model has a convex arc guide surface for limiting the tray base. The convex arc guide surface and the inner arc surface are combined to limit the position, so that the tray 16 can smoothly pass through the output transition channel and enter the interface output channel 10. It can also be seen that Figure 7 As shown, the output guide surface on the output guide plate 13 of the utility model is an inclined guide surface, and the inclined guide surface and the inner inclined surface are combined to limit the position, so that the tray 16 can smoothly pass through the output transition channel and enter the interface output channel 10.
