Abstract
Description
Technical Field
[0001] This utility model relates to the field of glove production, and in particular to a glove turning machine turning mold and turning mold assembly. Background Technology
[0002] Gloves are a widely used type of work protection product. They are generally produced by knitting gloves using glove knitting machines. After the gloves are produced by the glove knitting machine, they undergo subsequent processes, such as identifying defective gloves using automatic visual recognition equipment, bundling gloves using automatic glove bundling and packaging equipment, and turning gloves over using automatic glove turning equipment.
[0003] During the glove flipping process, a hand mold is used. The glove is placed on the first hand mold (also called the front hand mold or flipping hand mold), and then flipped onto the second hand mold (also called the rear hand mold or material-retrieving hand mold) by a flipping rod or flipping frame. Finally, the glove is removed from the material-retrieving hand mold by a material-retrieving mechanism, stacked, and then conveyed to a subsequent device for glove stacking and bundling.
[0004] The glove flipping mold consists of five hollow sleeves arranged side by side, with the five fingers of the glove fitting inside each sleeve. Existing flipping molds use circular tubes with a circular cross-section for the hollow sleeves. When flipping the glove onto the material-retrieving mold, this circular sleeve often results in wrinkles on the finger areas of the glove after removal. Utility Model Content
[0005] To address the problems of existing technologies, this utility model provides a glove flipping machine flipping mold and flipping mold assembly, which prevents the finger part of the flipped glove from forming wrinkles due to flattening, thus ensuring the quality of flipping.
[0006] The technical solution provided by this utility model is as follows:
[0007] A glove flipping machine flipping hand mold includes five hollow sleeves corresponding to the five fingers of the glove. The five hollow sleeves are arranged side by side at a predetermined interval. At least the front end portion of each hollow sleeve has a flat cross-section. The major axis of the cross-section of the flat structure is parallel to the plane of the glove flipping machine flipping hand mold.
[0008] Each hollow sleeve is provided with a guide core material; the guide core material is connected to a core material telescopic mechanism that controls the movement of the guide core material within the hollow sleeve along the length direction of the hollow sleeve, and the guide core material extends out of the front end of the hollow sleeve or retracts into the hollow sleeve under the control of the core material telescopic mechanism.
[0009] Furthermore, the front end of the hollow sleeve has a transition structure, the cross-section of which gradually decreases from back to front, and the front cross-section of the transition structure is the flat structure.
[0010] Furthermore, the flipping hand mold also includes a flipping frame, which is fitted over the outer side of the five hollow sleeves. The flipping frame is connected to a flipping frame drive mechanism that controls the movement of the flipping frame along the length of the hollow sleeves.
[0011] Furthermore, the flipping frame is provided with reflective strips, which are disposed on the upper surface of the flipping frame.
[0012] Furthermore, the flipping frame is equipped with an anti-collision buffer structure.
[0013] Furthermore, the front end of the flipping frame has a notch structure, the position of which corresponds to the junction of the thumb and index finger of the glove on the flipping hand mold.
[0014] A flipping hand mold assembly includes multiple flipping hand molds, which are installed at different positions on a rotating frame. The rotating frame is connected to a rotation drive mechanism that controls the rotation of the rotating frame. The rotating frame rotates so that the multiple flipping hand molds are simultaneously located at the nesting station and the flipping station.
[0015] Furthermore, the rotation axis of the rotating frame is set horizontally, and the flipping hand mold is installed on the rotating frame in a horizontal posture with a hollow sleeve.
[0016] Furthermore, the nesting station and the flipping station are symmetrically located above and below the rotating frame, respectively. The flipping hand molds are divided into two groups, each group including at least one flipping hand mold, and the two groups of flipping hand molds are symmetrically distributed on the rotating frame.
[0017] Furthermore, a horizontal rotating spindle is provided at the center of the rotating frame, and the rotating drive mechanism is connected to the rotating spindle.
[0018] Furthermore, the rotating frame reciprocates at a rotation angle of 180°;
[0019] Alternatively, the rotating frame rotates in one direction, with each rotation angle being 180°, and the rotating main shaft is equipped with an electrical reversing structure.
[0020] This utility model has the following beneficial effects:
[0021] This invention sets the front end cross-section of the hollow sleeve into a flat structure, which cooperates with the material-picking hand mold with flat fingers. When flipping the glove, the flat fingers of the material-picking hand mold are inserted into the flat structure at the front end of the hollow sleeve, and then the glove is flipped onto the material-picking hand mold. This ensures that the finger part of the glove removed from the material-picking hand mold will not be flattened and wrinkled, thus guaranteeing the quality of flipping. Attached Figure Description

[0026] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0027] This utility model embodiment provides a glove flipping machine flipping hand mold 1 or 1', such as Figure 1-2 As shown, the glove includes five hollow sleeves 7 corresponding to the five fingers. The five hollow sleeves 7 are arranged side by side with a set interval. The five hollow sleeves 7 can be installed together on a sleeve mounting block 8, so that the five hollow sleeves 7 form a whole.
[0028] At least the front end portion of the hollow sleeve 7 has a flat cross-section 17, that is, the front end portion of the hollow sleeve 7 has a flat cross-section 17. The cross-sections of other portions can be flat or circular, as is the case in the prior art. This application does not impose any restrictions on this.
[0029] The flat structure 17 can be an elliptical structure or a flat rectangular structure with rounded corners. The major axis of the cross-section of the flat structure 17 is parallel to the plane where the glove turning machine turning mold is located. Assuming that the plane of the glove turning machine turning mold 1 or 1' is set horizontally, then the long side of the cross-section of the flat structure 17 is also set horizontally.
[0030] Each hollow sleeve 7 contains a guide core 9. Five guide cores 9 can be mounted together on a core mounting block 10, forming a single unit. The guide cores 9 can be made of polytetrafluoroethylene (PTFE), which has good self-lubricating properties.
[0031] The guide core 9 is connected to a core material telescopic mechanism 11, which controls the movement of the guide core 9 within the hollow sleeve 7 along the length of the hollow sleeve 7. Under the control of the core material telescopic mechanism 11, the guide core 9 extends out of the front end of the hollow sleeve 7 or retracts into the hollow sleeve 7.
[0032] Specifically, the core material telescopic mechanism 11 can be connected to the core material mounting block 10, and simultaneously drive the telescopic movement of the five guide core materials 9.
[0033] The end of the guide core material 9 may have a guide transition structure, such as a conical or arc-shaped guide transition structure, to facilitate the glove's fingers to be slipped onto the hollow sleeve 7.
[0034] In existing technology, the hollow sleeve has a circular cross-section, and the fingers of the corresponding material-retrieving hand mold are also circular. After the glove is flipped from the flipping hand mold onto the material-retrieving hand mold, it is usually clamped onto the material-retrieving hand mold by two clamping mechanisms to remove the glove. Because the fingers of the glove are stretched into a circular shape by the material-retrieving hand mold, they will be flattened after removal. However, a circular shape is prone to wrinkling during the flattening process.
[0035] This utility model sets the front end cross-section of the hollow sleeve into a flat structure, which cooperates with the material-grabbing hand mold with a flat structure finger, as shown in Figure 18. Figure 3 As shown. When flipping, the flat fingers of the material-picking hand mold 18 are inserted into the flat structure at the front end of the hollow sleeve, and then the glove is flipped onto the material-picking hand mold 18. This ensures that the finger part of the glove removed from the material-picking hand mold 18 will not be flattened and wrinkled, thus guaranteeing the quality of flipping.
[0036] In one example, the hollow sleeve 7 has a transition structure 19 at its front end. The cross-section of the transition structure 19 gradually decreases from back to front, and the front part of the transition structure 19 has a flat structure 17. The transition structure 19 allows gloves to be easily put on the hollow sleeve 7.
[0037] The flipping hand mold 1 or 1' also includes a flipping frame 12, which is fitted onto the outer side of the five hollow sleeves 7. The flipping frame 12 is connected to a flipping frame drive mechanism 13 that controls the movement of the flipping frame 12 along the length of the hollow sleeves 7.
[0038] This utility model does not limit the specific structural form of the flipping frame 12; it can be any form of flipping frame already disclosed in the prior art, as long as it can achieve the flipping of gloves. For example, the flipping frame 12 can be... Figure 1 The flat sleeve structure shown fits around the five hollow sleeves 7. It can also be a part of this flat sleeve structure, such as the upper or lower half. The length of the flat sleeve structure can be shortened to form a ring-like structure, or the upper or lower half of a ring-like structure. For example, it can also be a shovel-shaped flipping frame, such as... Figure 4 As shown, Figure 4 The flipping frame shown can be set below the flipping hand mold 1, and the flipping is performed by the upward-sloping shovel.
[0039] The flipping frame drive mechanism 13 controls the flipping frame 12 to move, flipping the gloves on the flipping hand mold onto the material picking hand mold, thus flipping the gloves.
[0040] A reflective strip 14 may be provided on the flipping frame 12, and the reflective strip 14 is provided on the upper surface of the flipping frame 12.
[0041] The reflective strip 14 works in conjunction with a photoelectric sensor to detect whether the glove is correctly fitted onto the flipped hand mold. The photoelectric sensor is located above the flipped hand mold 1, with its detection direction pointing downwards towards the position of the glove's heel on the mold. Once the glove is correctly fitted onto the mold, the position of the glove's heel is fixed; therefore, the photoelectric sensor can detect this position, and when a glove is detected at that position, it is considered that the glove is correctly fitted onto the mold.
[0042] When there is no glove at the heel of the glove on the flipped hand mold 1, the light signal from the photoelectric sensor shines on the flipped hand mold 1, and the reflected light signal is received by the photoelectric sensor, thus determining that there is no glove at the heel of the glove on the flipped hand mold 1. The reflective strip 14 is attached to the position where the glove is located on the flipped hand mold 1 to enhance the reflective effect.
[0043] When a glove is present at the heel of the hand mold 1, the light signal from the photoelectric sensor shines onto the glove. Because the light signal undergoes diffuse reflection on the glove, the reflected signal intensity is low and insufficient to trigger the photoelectric sensor, thus indicating the presence of a glove. The sensitivity of the photoelectric sensor is adjustable, allowing it to be adjusted to a level where the reflected light from the glove does not trigger the sensor.
[0044] The reflective strip 14 is long and narrow, with its length along the direction of the fingers of the flipped hand mold 1, to accommodate gloves of different sizes.
[0045] The flipping frame 12 is equipped with an anti-collision buffer structure 15 to prevent the flipping frame from colliding and being damaged by other structures. The anti-collision buffer structure 15 can be a spring or a hydraulic buffer, etc.
[0046] In this utility model, the front end of the flipping frame 12 is provided with a notch structure 16, and the position of the notch structure 16 corresponds to the junction of the thumb and index finger of the glove on the flipping hand mold 1.
[0047] In the glove, the junction of the thumb and index finger is closer to the base of the glove than the junctions of the other fingers. To ensure the glove fits completely over the flipped hand mold, a notch structure is provided. The notch structure 16 is present on both sides of the flipping frame and is located in the same position. When the glove is placed on the flipped hand mold 1, the junction of the thumb and index finger is located within the notch, while the junctions of the other fingers are located at the front end of the flipping frame 12, ensuring that the glove fits completely over the flipped hand mold.
[0048] The glove-flipping process requires the glove to be fitted onto the flipping hand mold at the nesting station. Then, the flipping hand mold needs to be moved to the flipping station to flip the glove onto the material-picking hand mold. Finally, the flipping hand mold is returned to the nesting station to complete the fitting of the next glove. While the flipping hand mold is at the flipping station, the nesting station is idle and must wait for the flipping hand mold to return to its original position before it can operate. Similarly, while the flipping hand mold is at the nesting station, the flipping station is idle and must wait for the flipping hand mold to move before it can operate.
[0049] As can be seen from the above, during the entire process of turning the gloves over, the fabric and the turning process cannot be carried out simultaneously. A long waiting period is required, making it impossible to achieve continuous and uninterrupted turning work, resulting in low turning efficiency.
[0050] To address the aforementioned problems, this utility model embodiment also provides a glove turning machine turning hand mold assembly, such as... Figure 1 As shown, it includes multiple flipping hand molds 1 or 1' as described above. The multiple flipping hand molds 1 or 1' are installed at different positions on the rotating frame 2. For example, each flipping hand mold can be installed on the rotating frame 2 through its corresponding sleeve mounting block 8, so as to realize the connection between the flipping hand mold 1 or 1' and the rotating frame. The rotating frame 2 is connected to a rotation drive mechanism 3 that controls the rotation of the rotating frame 2.
[0051] The rotating frame 2 rotates so that multiple flipping hand molds 1 or 1' are simultaneously located on the nesting station 4 and the flipping station 5. That is, during the rotation of the rotating frame 2, when at least one flipping hand mold 1 is located on the nesting station 4, at least one flipping hand mold 1' is located on the flipping station 5, and when at least one flipping hand mold 1' is located on the flipping station 5, at least one flipping hand mold 1 is located on the nesting station 4.
[0052] This invention uses a rotating frame to rotate multiple flipping hand molds, so that some flipping hand molds are located at the nesting station and some flipping hand molds are located at the flipping station. Nesting and flipping can be performed simultaneously without long waiting times, achieving continuous and uninterrupted flipping work and improving flipping efficiency.
[0053] In one example, the rotating frame 2 is a frame structure with its rotation axis set horizontally, and the flipping hand mold 1 or 1' is installed on the rotating frame 2 in a horizontal posture with the hollow sleeve 7.
[0054] The aforementioned core material telescopic mechanism 11 and flipping frame drive mechanism 13 can both be mounted on the rotating frame and rotate together with the rotating frame and the flipping hand mold.
[0055] The nesting station 4 and the flipping station 5 can be symmetrically located 180° above and below the rotating frame 2, respectively. The flipping hand mold 1 or 1' is divided into two groups, each group including at least one flipping hand mold, and the two groups of flipping hand molds are symmetrically distributed on the rotating frame 2.
[0056] For example, there are four flipping hand molds. The four flipping hand molds are arranged in pairs. Each pair of flipping hand molds rotates alternately to the flipping station and the nesting station. Each time, two flipping hand molds are nested and flipped at the same time, which improves work efficiency.
[0057] To facilitate the driving of the rotating frame 2, a horizontal rotating main shaft 6 is set at the center of the rotating frame 2. The rotating drive mechanism 3 is connected to the rotating main shaft 6. The rotating frame 2 rotates under the drive of the rotating drive mechanism 3. The rotating drive mechanism 3 can be a motor and its equipped reduction and transmission mechanism, etc.
[0058] The rotating frame 2 can rotate reciprocally, for example, rotating reciprocally at a rotation angle of 180°. Reciprocating rotation can reduce the impact on its various circuits.
[0059] Alternatively, the rotating frame 2 can rotate in one direction, with each rotation angle being 180°. In this case, the rotating main shaft 6 is equipped with an electrical reversing structure, such as a brush ring, and a hydraulic rotary oil circuit.
[0060] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
