Description

Technical Field

[0001] The invention relates to the technical field of sock machine mechanisms, in particular to a sock turning mechanism for a sock machine. Background Art

[0002] The production process of sports socks requires the use of a sock machine, which has a flipping function. The socks need to be flipped after the sock opening is sewn, while the existing sock toe sewing mechanism clamps the sock toe for sewing, and then the socks are transported upside down after sewing.

[0003] For example, a sock production device provided by publication number CN104233634B adds a sock turning device at the rear end of the sewing machine to realize automatic turning over after the sock opening is sewn. When turning over, the fan works and the suction pipe draws air outward from the lower end of the sock guide tube. Since the sock guide tube is a hollow structure, the sock tube mounted on the sock guide tube is sucked out by the air flow from the lower end of the sock guide tube through the suction pipe, so that the socks that come out become the front side, thereby realizing automatic turning over.

[0004] The socks sewn by the toe-sewing machine are conveyed in an upside-down manner, and in this device, the sock opening is simply positioned by sucking the sock opening with air pressure, so it is easy for the sock opening to be difficult to fix and cause inaccurate turning over.

DETAILED DESCRIPTION

[0033] The embodiment of the present invention provides a sock turning mechanism for a sock machine, such as Figure 1-9 As shown, it includes a base 1, a control box 2 is fixedly installed on the top of the base 1, a vertical column 6 is fixedly installed on the top of the control box 2, a vertical support 3 is pivotally connected to the front of the control box 2, the column 6 and the support 3 are on the same axis, the column 6 is hollow inside, and is slidably fitted with a slider 7, and the top of the column 6 is connected to a delivery pipe 63.

[0034] A vertical pipe 4 is laid inside the pillar 3, and the vertical pipe 4 can be raised to enter the column 6. An annular bracket 8 is provided between the pillar 3 and the column 6, and a clamping assembly for clamping the sock tube is fixedly installed on the top of the annular bracket 8. A sewing assembly is fixedly installed on the left side of the control box 2. An air pipe 33 is connected to the left side of the pillar 3, and an air hole 41 is opened on the left side of the vertical pipe 4. An air pump is fixedly installed at the end of the air pipe 33.

[0035] The above-mentioned vacuum assembly, clamping assembly, and sewing assembly are all conventional technical means, and the specific structure, connection method, etc. are not described in detail.

[0036] A top cover 5 is fixedly installed on the top of the pillar 3. A groove is opened on the right side of the top cover 5. A grating 51 is fixedly installed in the groove. The center of the top cover 5 is connected to the vertical pipe 4. A baffle 53 is welded on the top of the top cover 5. A pressure sensor unit 531 is fixedly installed on the baffle 53. The control box 2 is electrically connected to each component, and the control box 2 is used to control the operation of each electronic component.

[0037] Working steps: deflect the pillar 3 to the right by 30°. During the deflection process, the sock body enters the groove to block the grating 51, and the sock body gradually contacts the pressure sensing unit 531. When the value measured by the pressure sensing unit 531 reaches within the preset range, the center of the grating 51 contacts the end of the sock body. At this time, the pillar 3 has been deflected, and the air pipe 33 is used to evacuate air to generate negative pressure in the vertical pipe 4, thereby sucking the sock tube into the vertical pipe 4.

[0038] A slider 7 is provided in the column 6, and a motor-driven screw 65 is symmetrically arranged in the column 6. The screw 65 threads penetrate through the slider 7, and the slider 7 is driven to move up and down by the forward and reverse rotation of the screw 65.

[0039] A central hole 71 is provided at the center of the slider 7, the vertical tube 4 extends into the column 6 and passes through the central hole 71, grooves 72 are symmetrically provided on the inner side of the central hole 71, a rubber strip 75 is arranged in the groove 72, chambers are symmetrically provided front and back in the slider 7, the chambers correspond to the grooves 72 one by one, a driving unit is provided in the chamber, and the tension of the rubber strip 75 is adjusted by the driving unit.

[0040] The clamping components are distributed in a ring shape on the top of the ring bracket 8, and the clamping components fix the top edge of the sock tube, thereby unfolding the upper end of the sock tube.

[0041] Working steps: When the socks are sucked into the vertical tube 4, the support 3 is reset to a vertical shape, the vertical tube 4 moves upward through the annular bracket 8, and the upper end of the vertical tube 4 contacts the outer wall of the upper end of the socks. As the vertical tube 4 continues to rise, the vertical tube 4 carries the socks into the column 6 and turns the inside of the socks to the outside.

[0042] At this time, the original top end of the sock tube becomes the bottom, the rubber strip 75 in the slider 7 is tightened to clamp the vertical tube 4, and the slider 7 drives the vertical tube 4 to rise, so that the upper end of the vertical tube 4 is inserted into the conveying tube 63, and the lower end of the vertical tube 4 is separated from the support 3 and enters the column 6, and the lower end of the vertical tube 4 is below the annular bracket 8.

[0043] The clamping assembly is rhythmically released, the slider 7 does not hold the vertical tube 4 and slowly descends a certain distance, the slider 7 pushes the sock tube to align the bottom of the sock tube with the sewing assembly, and the sewing assembly is used to sew the bottom of the sock tube together to make a sock.

[0044] The delivery tube 63 is connected to a vacuum assembly, which is used to form a negative pressure in the delivery tube 63 so that the socks are sucked into the vertical tube 4. At this time, the socks are turned over again with the inside facing inward, and finally delivered through the delivery tube 63.

[0045] The driving part is composed of a slide rail 73 and a motor 74. The slide rail 73 is fixedly installed in the chamber. A driving seat is slidably matched on the slide rail 73. A motor 74 is fixedly installed on the top of the driving seat. One end of the rubber strip 75 is fixedly installed with the inner wall of the groove 72. The other end of the rubber strip 75 extends into the chamber and is fixedly connected to the transmission shaft of the motor 74. The motor 74 rotates and winds the rubber strip 75, so that the rubber strip 75 is tightened.

[0046] A balance bar 56 is pivotally connected to the front of the top cover 5, a photoreceptor 55 is fixedly installed on the top of the top cover 5 and above the left end of the balance bar 56, a laser transmitter 54 is fixedly installed on the front of the top cover 5 and on the left side of the balance bar 56, a reflective coating 561 is coated on the surface of the balance bar 56, and a horizontal bar 52 is welded on the right side of the top cover 5. The horizontal bar 52 plays a blocking role to ensure that the sock body can enter the grating 51 during the movement of the pillar 3.

[0047] When the pillar 3 tilts 30°, the top cover 5 tilts along with the pillar 3 , and the balance bar 56 is still in a balanced state. At this time, the light emitted by the laser emitter 54 is reflected and just irradiates the photoreceptor 55 .

[0048] A ferrule 62 is slidably fitted on the top of the column 6, the upper end of the ferrule 62 is connected to the delivery pipe 63, the lower end of the ferrule 62 extends into the column 6, the upper end of the vertical pipe 4 can be inserted into the lower end of the column 6, and the ferrule 62 is used to connect the column 6 and the delivery pipe 63 together.

[0049] There is a flange at the top of the ferrule 62 , and a small electric push rod 64 is fixedly installed between the flange and the top of the column tube 6 , and a glass cover 61 is fixedly installed on the front of the column tube 6 .

[0050] The small electric push rod 64 is extended to make the ring 62 descend, and the lower part of the ring 62 blocks the air hole 41, so that the socks can be drawn into the vertical tube 4 by suction and finally discharged from the conveying tube 63.

[0051] A plurality of motor-driven rubber wheels 31 are pivotally connected to the inner side of the pillar 3, a rubber ring 32 is fixedly installed at the bottom of the pillar 3, and a recess 42 matching the rubber ring 32 is formed in the shaft of the vertical tube 4. The rubber ring 32 cooperates with the recess 42 to position the vertical tube 4.

[0052] The bottom of the annular bracket 8 is pivotally connected with an arc-shaped piece 82 driven by a motor, and the right side of the annular bracket 8 extends outward and is fixedly installed with a second motor 81. After the socks are placed, the second motor 81 drives the annular bracket 8 to deflect, so that the annular bracket 8 and the socks are moved to the bottom of the column 6. The arc-shaped piece 82 is turned over to clamp and merge the ends of the socks, so that the sewing assembly can sew the bottom ends of the socks together.

[0053] A cylinder 11 is fixedly installed on the left side of the base 1, and a rubber pad 12 is fixedly installed on the movable end of the cylinder 11. A large electric push rod 21 is fixedly installed on the back of the control box 2. The control box 2 is pivotally connected with a rotating shaft 22. The movable end of the large electric push rod 21 is hinged to the rod body of the rotating shaft 22, and the front end of the rotating shaft 22 is welded to the support 3.

[0054] The large electric push rod 21 is extended and retracted to drive the support 3 to move, so that the sock is sucked into the front of the vertical pipe 4, and the cylinder 11 is extended to make the rubber pad 12 block the bottom of the vertical pipe 4, so that negative pressure can be generated in the vertical pipe 4 during the air extraction process.

[0055] In summary, the sock turning mechanism for the sock machine is composed of a support 3, a vertical tube 4, and a column 6. The top of the support 3 is connected to a top cover 5, which is used to sense whether the support 3 is tilted in place and whether the end of the sock is just aligned with the upper end of the vertical tube 4 through the cooperation of the grating 51, the pressure sensing unit 531, the laser emitter 54, and the photoreceptor 56, so as to achieve the function of positioning the sock opening, and improve the accuracy of turning the sock with the help of the vertical tube 4. The sock is sucked into the vertical tube 4 by means of air extraction, and then the vertical tube 4 is extended into the column 6 to turn the sock over, which is convenient for the subsequent sewing of the lower end into socks, and then the sock is sucked into the vertical tube 4 by air extraction, and sent out from the conveying pipe 63 to achieve the purpose of transporting socks.
