Description

Technical Field

[0001] This invention relates to the field of glove machines, and specifically to a glove machine slub positioning and clamping device. Background Technology

[0002] The basic structure of a traditional computerized glove machine is as follows: between the left and right bases, there are front and rear needle beds and corresponding front and rear knitting heads; the needle beds are equipped with movable combination knitting needles; the front and rear knitting heads move back and forth relative to the needle beds through a slide rail assembly; the side of the knitting head facing the needle bed is equipped with a triangular base plate, and various triangles are set on the triangular base plate. The needle heels of the combination knitting needles complete various knitting functions through the restriction and function of the triangles.

[0003] After the gloves are knitted, they fall downwards between the front and rear needle beds. To automate the sorting of these fallen gloves, the applicant has filed a series of prior patents related to automated glove sorting, such as "CN113604954B," which uses an automatic gripping device between the front and rear needle beds to neatly stack the gloves onto a receiving platform. Following this, the applicant filed another patent, "Automatic Binding System CN115593680A," which, in conjunction with "Pushing Device CN115384860A," achieves a fully automated process for glove production, sorting, and binding.

[0004] Furthermore, depending on the requirements, some gloves need to be turned inside out after knitting to facilitate subsequent labeling. Therefore, in "CN117107504A Glove Turning and Stacking Process", the applicant designed a process for automatically turning the gloves inside out before stacking and sorting. The technical solution involved requires positioning the cuff of the glove (i.e., the opening at the wrist of the glove) in order to insert the clamping expansion mechanism into the cuff of the glove.

[0005] Since the applicant disclosed its glove finishing technology, all gripping devices, including patents and products disclosed by peer companies, have adopted a two-arm opening and closing method. Due to the limitations of the glove machine needle bed, the gripping part of these two arms for the glove cuff is generally located near the palm of the wrist (the fingers are downward when the glove is knitted). The relatively soft nature of knitted gloves causes the glove cuff to be in a swinging state, which makes it difficult for the mechanism that grips and expands the cuff to position the glove cuff in one step when turning it over, thus affecting the glove turning efficiency.

[0006] Therefore, the inventors conducted further research and developed a glove machine grommet positioning and clamping device, which led to this invention. Summary of the Invention

[0007] The purpose of this invention is to provide a glove machine cuff positioning and clamping device, which can position and clamp the glove cuff after the glove is knitted, thereby facilitating subsequent finishing or turning.

[0008] To achieve the above objectives, the technical solution of the present invention is as follows:

[0009] A glove machine cuff positioning and clamping device, comprising:

[0010] The gripping part is positioned below the front and rear needle beds of the glove machine. The gripping part includes two arms that can open and close relative to each other. At least one of the arms is provided with a rolling element. When the two arms open and close, the rolling element can accommodate movement between the front and rear needle beds. The rolling element moves the glove relative to the rolling element by rotating or rolling.

[0011] In existing technologies, once the gripping unit grasps the glove, the glove's position relative to the gripping unit remains unchanged until the gripping unit places the glove on the receiving platform. Therefore, it cannot accurately fix the glove's cuff position, easily causing the cuff to tilt. The technical solution of this invention satisfies both the need for automatic sorting (more precise stacking, neater glove stacking) and the need for positioning the cuff when the glove is turned over.

[0012] Furthermore, the rolling element is positioned laterally relative to the two arms.

[0013] The lateral setting refers to the direction of the back-and-forth movement of the machine head, which means that the rolling element can enter the narrow space between the front and rear needle beds, while ensuring that the rolling element can adapt to the width of the glove.

[0014] Furthermore, the rolling element is a ball, a roller, or a shaft; when the rolling element is a ball or a roller, the ball or roller is mounted on a fixed seat; when the rolling element is a shaft, the shaft rolls or rotates based on its own fixed axis.

[0015] Here, "roller" refers to a cylindrical machine part that can roll. Bearings should also be considered a type of roller. Any device that can cause relative movement of the glove through rolling elements falls within the scope of this invention.

[0016] Furthermore, the roller or shaft is provided with several protrusions or ridges, which are continuously distributed.

[0017] Raised or raised strips are used to increase the friction on the gloves, making it easier for rollers or shafts to lift and lower the gloves.

[0018] Furthermore, the two arms include a fixed arm and a movable arm, with the movable arm being driven by a motor to open and close relative to the fixed arm.

[0019] Furthermore, the rolling elements on the fixed arm are driven to rotate or roll by a motor, while the rolling elements on the movable arm are passively rotated or rolled.

[0020] When both the movable arm and the fixed arm are equipped with rolling elements, it is not necessary to set both rolling elements as driving elements.

[0021] Furthermore, the motor that drives the opening and closing of the movable arm and the motor that drives the rolling elements to rotate are the same motor.

[0022] Both can be driven by the same motor through a linkage mechanism.

[0023] Furthermore, the rolling element set on the fixed arm is the driving shaft, and the rolling element set on the movable arm is the driven shaft. The driving shaft is linked to the motor through a synchronous belt.

[0024] Furthermore, a rocker arm is installed on the motor, and a tension spring is installed between the movable arm and the fixed arm. The rocker arm moves the movable arm to open the two arms, and the tension spring pulls the movable arm to close the two arms.

[0025] Furthermore, a check pawl is pivotally connected to the end of the swing arm, and a protrusion is provided at the end of the movable arm. When the check pawl rotates forward, it is restricted by the swing arm and pushes the movable arm. When the check pawl rotates in reverse, it is blocked by the movable arm and swings.

[0026] This structure is just one embodiment of a system in which the motor that drives the opening and closing of the movable arm and the motor that drives the rolling element to rotate are the same drive source.

[0027] By adopting the above solution, the present invention has the following advantages compared with the prior art:

[0028] The automatic glove gripping function achieves precise positioning of the glove cuff, which not only meets the needs of automatic sorting but also the need to position the cuff when turning the glove inside out, further enriching the automated production functions of gloves.

[0037] Platform 7. Detailed Implementation

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] A glove machine cuff positioning and clamping device, applied to a computerized glove machine, which moves between the front and rear needle beds by driving a gripping part. Figure 1 Only the front needle bed 5 is shown, waiting for the gripping unit to grasp the glove during knitting. After the glove is knitted, the gripping unit grasps the glove through its opening and closing arms. After grasping, the rolling action of the rollers on the arms causes the glove cuff to descend relative to the arms. When the glove cuff descends to a predetermined position (this position can be preset according to actual needs), the gripping unit can choose to directly transport the glove to the receiving platform 7 for stacking and arranging, as disclosed in CN113604954B, or it can choose to cooperate with the clamping and expanding mechanism 6, as disclosed in CN117107504A, to first transfer the glove to the flipping mechanism for flipping, and then transport it to the receiving platform 7 for stacking and arranging. Subsequently, it will be automatically tied with the binding mechanism. The clamping and expanding mechanism includes at least two expanding members, which fix or expand the glove cuff by moving, swinging, or clamping.

[0040] The movement of the gripping part itself can be achieved by several drive sources, which can make it rise and fall and move relative to the needle bed. This concept has been involved in the prior art CN113604954B, which uses one drive source to achieve rising and falling and another drive source to achieve falling. Alternatively, a guide plate can be set up, such as "CN218561778U", to achieve rising and falling and falling.

[0041] like Figure 2 As shown, the gripping unit includes a fixed arm 1 and a movable arm 2. Both the fixed arm 1 and the movable arm 2 have a transverse roller at their ends. The roller has ridges and grooves spaced apart. The roller on the fixed arm 1 is a drive shaft 11. One end of the drive shaft 11 is linked to a motor 3 below via a synchronous belt 12. The drive shaft 11 rotates under the drive of the motor 3, while the passive shaft 21 rotates after the two arms are closed, driven by the drive shaft 11. In actual manufacturing, for convenience, the fixed arm can also be connected to a fixed plate, but functionally, these two should be considered as one unit.

[0042] Alternatively, a rolling element with rolling capability (such as several rollers or a similar device capable of rolling or rotating) can be set on the fixed arm 1, while an auxiliary transverse arm (even if it does not have rolling or rotating capability) can be set on the movable arm 2. The positioning of the glove cuff can be achieved by a single rolling element, but the positioning efficiency is slightly lower than that of two rolling elements.

[0043] Figure 2 A type of joint is also provided between the fixed arm 1 and the movable arm 2. Figure 3 The tension spring 4 shown is used to open the movable arm 2 via a motor 3 driving a rocker arm 31, which in turn moves the lower end of the movable arm 2. The movable arm 2 itself is pivotally connected to the fixed arm 1. The end of the rocker arm 31 has a ratchet-like anti-return pawl 32, and the lower end of the movable arm has a protrusion 22 (typically a bolt). Figure 3 Taking the angle as an example, the check pawl 32 is pivotally connected to the rocker arm and restricted by the rocker arm 31, allowing it to rotate to the left but not to the right. That is, when the check pawl 32 moves to the left, it pushes the movable arm 2 via the protrusion 22, causing the driven shaft 21 on the movable arm 2 to open relative to the driving shaft 11. When the check pawl 32 disengages from the movable arm 2, the movable arm 2, under the action of the tension spring 4, closes the driven shaft 21 with the driving shaft 11 (see reference). Figure 4 , Figure 5 When the check pawl 32 rotates to the right, it will not affect the movable arm 2.

[0044] The aforementioned use of the anti-return pawl 32 is because the opening and closing of the fixed arm 1 and the movable arm 2, as well as the rotation of the drive shaft 11, are all driven by the same motor 3. That is, if the drive shaft 11 and the driven shaft 21 need to pull the glove down, in order to... Figure 4 For example, the active shaft 11 rotates clockwise and the passive shaft 21 rotates counterclockwise, so that the glove between the two shafts is subjected to a downward pulling force. At this time, the movable arm 2 and the fixed arm 1 are in a closed state. The clockwise rotation of the swing arm 31 and the check pawl 32 will not affect the above action. The check pawl 32 itself can be kept in a relatively vertical state by a torsion spring.

[0045] Before grasping the glove, the movable arm 2 needs to be opened from the fixed arm 1. The swing arm 31 needs to act on the movable arm 2, therefore the check pawl 32 needs to be in a "force transmission" state, such as... Figure 3 As shown.

[0046] The main innovation of this invention is that while the glove machine has automatic sorting capabilities, it can also accurately position the knitted glove cuffs, thereby making the automatic sorting of gloves more neat, or better cooperating with the turning mechanism to turn the gloves inside out.

[0047] Using the same motor 3 to drive the opening and closing of both arms and the rotation of the drive shaft 11 is a preferred technical solution based on the above-mentioned innovations. It is only a specific embodiment of the present invention. At the same time, all terms such as "upper," "lower," "left," "right," and "middle" involved in the present invention are for reference only and are not absolute limitations. Any non-substantial modifications made using the present invention shall be considered as infringing the scope of protection of the present invention.
