Description

Technical Field

[0001] This utility model relates to the technical field of glove production equipment, specifically to a material hopper device for a glove blanking machine and a glove blanking machine. Background Technology

[0002] A glove preform fitting machine is a key piece of equipment in the glove production process, used to fit preformed gloves onto glove molds. A preform fitting machine typically includes a hopper, a conveying device, and a mold fitting device. The hopper temporarily stores the preforms, the conveying device retrieves them from the hopper and transports them to the mold fitting device, which then fits the preforms onto the glove mold. Existing preform fitting machines suffer from the following problems in practical applications: During the glove-making process, several stacked glove blanks are temporarily stored in the hopper. Several hand-operated units in the conveying device sequentially pick up and transport each glove blank through reciprocating motions. For example, in an automatic glove-making machine disclosed in patent CN120056325A, the upper gripper grabs gloves from the feeding device. However, adjacent glove blanks may stick together, making it easy for the hand-operated unit to pick up a single glove blank while simultaneously pulling up the glove blank below it. This causes the original position of the lower glove blank to shift, leading to subsequent material retrieval failures and ultimately resulting in a failed glove-making process.

[0003] Based on this, this utility model proposes a material hopper device and a glove preform forming machine, which can avoid the failure of preform forming due to displacement caused by the glove preforms sticking together. Furthermore, considering the following limitations of the prior art, a preferred solution is proposed: First, some glove preforms (such as work gloves) have a locked edge design at the wrist. When multiple glove preforms with locked edges at the wrist are stacked, the excess thickness at the wrist (compared to the palm and fingers) will cause excessive warping and messiness, which is not conducive to accurate material handling. Second, existing preform forming machines are mostly single-hopper or double-hopper designs. Single-hopper machines have limited storage capacity, and when the specifications of the glove preforms to be processed change, the single-hopper machine must be stopped for reloading. In comparison, although double-hopper machines can increase storage capacity, when the second hopper is used to increase storage capacity, it can only hold glove preforms of the same specifications as the first hopper. In this case, the problem of needing to stop and reload when the glove preform specifications change also exists, making continuous production impossible. Third, in order to facilitate the accurate and efficient execution of the glove blanking process, it is often necessary to align the glove blank before glove blanking so that the glove blank reaches the position that precisely corresponds to the glove blanking part. In the existing technology, the alignment device often adopts an inclined platform with a front baffle. After the glove blank is released onto the inclined platform by the material conveying device, it will naturally slide down, thereby forming the effect of wrist alignment. However, this method is prone to failure to slide down into place, and its reliability is not high. Utility Model Content

[0004] The purpose of this utility model is to provide a material hopper device and a glove preformer making machine to solve the problem mentioned in the background art, in which existing glove preformer making machines cannot avoid the glove preforms from sticking together and shifting during material handling, thus causing preformer making failure; it also further solves the problems of negative impact on preformer making operation caused by the lifting of the locking edge wrist, insufficient material hopper design, and unreliable alignment operation.

[0005] This utility model is achieved using the following technical solution: A hopper device for a glove preform forming machine includes a hopper body. The hopper body includes a horizontally arranged base plate and a baffle plate. The baffle plate is located on the front side of the base plate. The base plate also has several parallelly arranged material picking positions. In this technical solution, following industry convention, the direction of glove preform transfer is defined as the forward direction, and the horizontal direction corresponds to the left-right direction. A positioning component is provided above the hopper body. The positioning component applies downward pressure to the stacked glove preforms in the picking positions. The positioning component includes several positioning actuators, each corresponding to one of the picking positions.

[0006] In the above solution, by applying downward pressure to the stacked glove blanks through the positioning component, the situation where the glove blanks below are stuck together and pulled up when the upper glove blank is taken out can be avoided. Specifically, under the external force of the material picker in the feeding device, the upper glove blank can be pulled out from below the positioning component; the glove blanks below the upper glove blank are not directly subjected to the grasping force of the material picker and cannot be stuck together and pulled up by the natural adhesion between the glove blanks.

[0007] Furthermore, the positioning component applies downward pressure to the finger area of ​​the stacked glove blanks.

[0008] In the above solution, considering that the picking hand usually picks up the wrist area of ​​the glove blank, a positioning component is set to apply pressure to the finger area of ​​the glove blank to avoid the picking hand and prevent picking failure due to excessive pressure area.

[0009] Furthermore, the positioning assembly also includes a bracket, a lifting drive mechanism, and a crossbeam; the lifting drive mechanism is mounted on the bracket, and the output end of the lifting drive mechanism is connected to the crossbeam; a plurality of positioning actuators are connected to the crossbeam, and each positioning actuator includes a connector and a positioning component, one end of the connector being connected to the positioning component and the other end being connected to or cooperating with the crossbeam. In the above scheme, the execution of the positioning action is controlled by a lifting drive mechanism, that is, the positioning actuator is lowered to perform positioning and the positioning actuator is raised to stop positioning, so as to adapt to the working process of the silo device.

[0010] Furthermore, the positioning component also includes a guiding mechanism, which includes several guide rods, each of which is connected to a crossbeam; the bracket is provided with several limiting structures, and the guide rods slide through the limiting structures respectively.

[0011] In the above scheme, the guiding mechanism is used to guide the lifting action to improve the stability of the positioning actuator when it rises and falls.

[0012] Furthermore, the connecting member is a connecting vertical rod, and the positioning member is a pressure plate; one end of the connecting vertical rod passes through the crossbeam and can move relative to the crossbeam, the other end of the connecting vertical rod is fixedly connected to the pressure plate, and a limit member is provided at the end of the connecting vertical rod near the crossbeam.

[0013] In the above scheme, the pressure plate can continuously apply downward pressure to the stacked glove blanks based on its own gravity. Specifically, after the lifting drive mechanism lowers the pressure plate to a specified height, the pressure plate will contact the stacked glove blanks and apply pressure to them. As the number of glove blanks gradually decreases, the pressure plate will automatically fall relative to the crossbeam based on its own gravity, so as to achieve the effect of always applying pressure to the stacked glove blanks.

[0014] Furthermore, the lifting drive mechanism includes a servo motor and a transmission component, the connecting member is a connecting spring, and the positioning member is a pressure plate; one end of the connecting spring is connected to the crossbeam and the other end is connected to the pressure plate.

[0015] In the above scheme, the pressure plate applies downward pressure to the stacked glove blanks based on the elastic force of the connecting spring. Specifically: after the lifting drive mechanism lowers the pressure plate to a specified height, the pressure plate contacts the stacked glove blanks. At this time, the connecting spring is in a compressed state, and the pressure plate applies pressure to the glove blanks based on its elastic force. As the number of glove blanks gradually decreases, the deformation of the connecting spring gradually shrinks, thereby continuously reducing the pressure applied by the pressure plate to the glove blanks. When the deformation of the connecting spring shrinks to a threshold, the lifting drive mechanism lowers the pressure plate again to compensate for the shrinkage of the connecting spring deformation, thus controlling the pressure applied by the pressure plate within an effective range. Since the falling distance required to compensate for the spring deformation is relatively small, the lifting drive mechanism needs to use high-precision components, such as servo motors.

[0016] Furthermore, each of the material taking positions is provided with a recessed portion, which is located at the front of the material taking position; partitions are respectively provided on both sides of the front of each material taking position, and the recessed portion of each material taking position is located between the partitions on both sides. In the above solution, the recessed part is used to accommodate the wrist seam of the glove blank, thereby compensating for the extra thickness of the wrist seam (compared to the palm and finger positions), and thus avoiding excessive curling and mess at the wrist position after multiple glove blanks are stacked.

[0017] Furthermore, the front side of the recess is a baffle and the rear side is a support structure. The support structure includes an inclined section and / or a horizontal section, and the height of the support structure and the recess decreases from back to front.

[0018] In the above scheme, the horizontal section of the support structure can be used to place the palm area of ​​the glove blank, while the inclined section is used to lift the finger area of ​​the glove blank to a certain extent to prevent the wrist locking edge of the glove blank from sliding out of the recess when the positioning component presses down on the finger area.

[0019] Furthermore, the support structure is an integrated segmented support platform including a horizontal section and an inclined section. The segmented support platform is installed on the base plate, and the space between the segmented support platform and the baffle forms a recess. In the above scheme, by setting up segmented support platforms, the height difference between them and the base plate naturally forms a recess, so there is no need to specially create a recess on the base plate.

[0020] Furthermore, the portion of the bottom plate near the baffle is recessed downwards to form the recessed portion.

[0021] Furthermore, the support structure includes an inclined platform providing an inclined section, the inclined platform being disposed on a non-recessed portion of the base plate.

[0022] In the above scheme, by creating a recess in the base plate, the base plate itself can serve as a horizontal section, so there is no need to set up an additional horizontal section structure; only an inclined platform as an inclined section is required.

[0023] A glove preform fitting machine includes a frame, a material conveying device, and a mold fitting device. The material conveying device is used to pick up and convey glove preforms, and the mold fitting device is used to fit the glove preforms onto a hand mold. It also includes a material hopper device for the glove preform fitting machine, which is a preprocessing device of the material conveying device and is used to temporarily store glove preforms.

[0024] In the above solution, the preform assembly machine is equipped with a positioning hopper device, which prevents the preforms from sticking and being pulled up. This ensures that when the conveying device takes the preforms out of the hopper device, the original position of the preforms below will not be moved, thus ensuring the smooth operation of the preform assembly process.

[0025] Furthermore, the hopper device is configured to receive glove blanks that need to be temporarily stored at the feeding station, and the conveying device is configured to retrieve glove blanks from the hopper device at the retrieving station; a waiting station is provided between the feeding station and the retrieving station; the hopper device includes N hopper bodies, N≥3, and the N hopper bodies are configured to circulate between the feeding station, the waiting station, and the retrieving station.

[0026] In the above scheme, by setting up at least three main silos, the needs for both spare materials of the same specification and pre-loaded materials of different specifications can be met simultaneously, thereby meeting the needs of continuous production. Specifically, taking three main silos as an example, when silo one is loaded with glove blanks of specification one and is in the process of being picked up, glove blanks of specification one can be loaded in advance on silo two as spare materials of the same specification, and glove blanks of specification two can be loaded in advance on silo three as pre-loaded materials of different specifications. Based on this, silo one and silo two can be used alternately to meet the continuous production needs of glove blanks of the same specification, while silo three can quickly respond to the continuous production needs when the specifications of glove blanks change.

[0027] Furthermore, the silo device also includes N silo drive mechanisms, which are respectively connected to N silo bodies. The N silo drive mechanisms are configured to drive the N silo bodies to move between the feeding station, the waiting station, and the picking station. The silo drive mechanism includes a translational motion drive sub-mechanism and / or a lifting motion drive sub-mechanism.

[0028] In the above scheme, the N hopper bodies change positions through translational movement or translational movement and lifting action, that is, they can move between the three workstations; the N hopper drive mechanisms are arranged to avoid collisions during the operation.

[0029] Furthermore, the preceding process of the molding device is provided with an alignment device, which includes a sorting platform, an alignment baffle, a flipping drive mechanism, and several limiting baffles. The alignment baffle is connected to the front side of the sorting platform, the output end of the flipping drive mechanism is connected to the sorting platform, and the several limiting baffles form multiple alignment positions in pairs, with the multiple alignment positions arranged side by side on the sorting platform.

[0030] Furthermore, the flip drive mechanism is configured to flip forward multiple times to align the glove blanks; the flip drive mechanism is configured to flip backward to clean up the glove blanks left on the sorting platform.

[0031] In the above scheme, the alignment device is used to align the glove blanks before molding. Specifically, the feeding device places the glove blanks onto the alignment positions on the sorting platform. Then, the flipping drive mechanism controls the sorting platform to tilt multiple times towards the side where the alignment baffle is located, so that the glove blanks slide down and achieve an alignment effect under the obstruction of the alignment baffle. Afterward, the flipping drive mechanism controls the sorting platform to return to a horizontal state so that the feeding device can remove the glove blanks. Based on this, after the feeding device has completed the material removal operation, the flipping drive mechanism can again control the sorting platform to tilt towards the opposite side of the side where the alignment baffle is located, so that any remaining glove blanks slide off, thereby avoiding affecting subsequent glove blanks.

[0032] Furthermore, the limiting partition is provided with a bend, which divides the limiting partition into a parallel segment and an opening segment. The parallel segment is perpendicular to and adjacent to the alignment baffle, and the opening segment is located on the side of the parallel segment away from the alignment baffle. The two limiting partitions in each group are arranged opposite each other, and the parallel segments of the two limiting partitions are parallel to each other, while the opening segments are arranged in a figure-eight shape.

[0033] In the above scheme, the shape of the limiting partition is adapted to the shape of the glove blank, that is, the parallel section corresponds to the wrist area of ​​the glove blank and the open section corresponds to the finger area of ​​the glove blank, thereby making the limiting effect on the glove blank better.

[0034] Furthermore, the alignment device also includes an opening and closing drive mechanism, which is configured to drive two limiting partitions in each group to move synchronously towards or away from each other.

[0035] In the above scheme, the opening and closing drive mechanism controls the two limiting partitions to move synchronously towards or away from each other, which can achieve the centering and positioning of the glove blank; and by adjusting the distance of the approaching or separating movements, it can flexibly adapt to gloves of different specifications.

[0036] The beneficial effects achieved by this utility model are: A material hopper device for a glove preform forming machine is provided. By setting a positioning component, the glove preform below can be prevented from sticking and being pulled up when the upper glove preform is taken out, thus avoiding displacement and failure of glove forming.

[0037] Based on the positioning components, a recessed part is further designed to accommodate the wrist edge of the glove blank, which can prevent excessive lifting and messiness at the wrist position after multiple glove blanks are stacked, thus avoiding adverse effects on material handling.

[0038] A glove preform assembly machine is provided, which solves the problem of preform assembly failure caused by the displacement of the lower glove preform due to the above-mentioned hopper device. On this basis, at least three hopper bodies and alignment devices are further set up, which can simultaneously realize the same specification of spare material and different specification of pre-loaded material to meet the needs of continuous production, and achieve a good alignment effect of glove preform before preform assembly.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0041] Example 1 This embodiment provides a hopper device and a glove blanking machine including the hopper device. Specifically: please refer to... Figure 1 The glove preform assembly machine also includes a frame 1, a material conveying device, and a die-fitting device. The material hopper is a pre-process device preceding the material conveying device, used to temporarily store the glove preforms. The material conveying device is used to pick up and transport the glove preforms. The die-fitting device is used to fit the glove preforms onto the hand mold. Wherein: Please refer to Figure 2The material conveying device includes a horizontal moving frame 21, a lifting mechanism 22, a mounting rod 23, and several material grippers 24, specifically: The horizontal moving frame 21 consists of a translation mechanism ( Figure 2 Not shown in the image, please refer to the following: Figure 1 The lifting mechanism 22 is installed on the horizontal moving frame 21 and the output end of the lifting mechanism 22 is connected to the mounting rod 23. The lifting mechanism 22 drives the mounting rod 23 to move up and down. Several material picking claws 24 are evenly connected on the mounting rod 23. The material picking claws 24 are controlled to open and close by the corresponding driving mechanism. The opening size can be adjusted to adapt to different materials.

[0042] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 The hopper device includes a hopper body and a positioning component, with the positioning component located above the hopper body, specifically: The main body of the hopper includes a bottom plate 31, a baffle 34, and several partitions 32. With the transfer direction of the glove blank as the forward direction, the baffle 34 is connected to the front side of the bottom plate 31, and several partitions 32 are arranged on the bottom plate 31 and perpendicular to the baffle 34. In this embodiment, several partitions 32 are grouped in pairs, and there is a material picking position between two partitions 32 in each group. Multiple material picking positions are arranged side by side. The positioning assembly applies downward pressure to the finger areas of the stacked glove blanks in the picking position. The positioning assembly includes a bracket 33, a lifting drive mechanism, a crossbeam 39, a guide mechanism, and several positioning actuators, wherein: The bracket 33 is mounted on the frame 1, and the lifting drive mechanism is mounted on the bracket 33. The output end of the lifting drive mechanism is connected to the crossbeam 39. The guide mechanism includes two guide rods 38, which are respectively connected to the crossbeam 39 and located on both sides of the lifting drive mechanism. Two limiting structures located on one side of the bracket 33 are connected to the bracket 33. In this embodiment, the limiting structure is specifically a limiting ring (in other embodiments, it can also be set as a limiting hole). The two guide rods 38 slide through the two limiting rings respectively.

[0043] Several positioning actuators are connected to the crossbeam 39, and the horizontal positions of the actuators correspond to the horizontal positions of multiple material handling positions. Each positioning actuator includes a connector and a positioning element. One end of the connector is connected to the positioning element, and the other end is connected to or engages with the crossbeam. In this embodiment, the lifting drive mechanism uses a cylinder 37, the connector uses a connecting vertical rod 36, and the positioning element uses a circular pressure plate 35. One end of the connecting vertical rod 36 passes through the crossbeam 39 and is movable relative to it. The other end of the connecting vertical rod 36 is fixedly connected to the pressure plate 35, and a limiting element is provided at the end of the connecting vertical rod 36 near the crossbeam 39. In this embodiment, the connecting vertical rod 36 moves relative to the crossbeam 39 through a bushing (not shown in the figure) embedded in the crossbeam 39. One end of the connecting vertical rod 36 passes through the bushing, and the other end is connected to the pressure plate 35. The limiting member (not shown in the figure, which can be set as a limiting ring sleeved on the outer periphery of the end of the connecting vertical rod 36, or at least two limiting rods connected to the end of the connecting vertical rod 36, etc.) is used to ensure that the connecting vertical rod 36 will not fall off the crossbeam 39. For example, when the positioning actuator is raised, the crossbeam 39 moves upward and the pressure plate 35 is in a free hanging state. The limiting member will be stuck on the crossbeam 39 so that the connecting vertical rod 36 will not fall off.

[0044] Based on the above structure, the hopper device and glove blank forming machine provided in this embodiment can solve the problem of the glove blanks sticking and being pulled up below them when they are taken out. Specifically: Under the control of the relevant control mechanism, after the cylinder 37 lowers the pressure plate 35 to a designated height, the pressure plate 35 will contact the stacked glove blanks and apply pressure to them based on its own weight. As the number of glove blanks gradually decreases, the pressure plate 35 will automatically fall based on its own weight and the free sliding of the connecting vertical rod 36 in the bushing, so as to always apply pressure to the currently stacked glove blanks. Thus, under the external force of the picking claw 24, the upper layer of glove blanks can be pulled out from under the pressure plate 35. Under the downward pressure applied by the pressure plate 35, since the lower glove blanks are not directly subjected to the gripping force of the picking claw 24, they cannot be picked up by the natural adhesion between the glove blanks alone.

[0045] Example 2 This embodiment provides a hopper device and a glove fabrication machine including the hopper device, which differs from Embodiment 1 in that: Please refer to Figure 6 In this embodiment, the lifting drive mechanism in the positioning component includes a drive component and a transmission component 311. In this embodiment, the drive component is specifically a servo motor 310, and the transmission component 311 is specifically a gear and rack 69 assembly (in other embodiments, it may also be a belt assembly, a linear sliding module, etc.). The connecting component is a connecting spring 312; one end of the connecting spring 312 is connected to the crossbeam 39, and the other end is connected to the pressure plate 35.

[0046] Based on the above structure, the working principle of this embodiment is as follows: Under the control of the relevant control mechanism, the servo motor 310 and the transmission component 311 lower the pressure plate 35 to a specified height, so that the pressure plate 35 contacts the stacked glove blanks. At this time, the connecting spring 312 is in a compressed state, and the pressure plate 35 applies pressure to the glove blanks based on the elastic force. As the number of glove blanks gradually decreases, the deformation of the connecting spring 312 will gradually decrease, thereby continuously reducing the pressure applied by the pressure plate 35 to the glove blanks. When the deformation of the connecting spring 312 decreases to a threshold, the servo motor 310 and the transmission component 311 lower the pressure plate 35 again to compensate for the reduced deformation of the connecting spring 312, thereby controlling the pressure applied by the pressure plate 35 within an effective range.

[0047] Example 3 This embodiment provides a hopper device and a glove blanking machine including the hopper device, which has the following further improvements based on Embodiment 1: Please refer to Figures 7 to 9 Each material taking position between two partitions 32 is provided with a recess 42, which is used to accommodate the wrist seam of the glove blank. Specifically, the recess 42 is located at the front of the material taking position, and the height of the recess 42 is determined based on the total thickness of the wrist seams of the glove blanks stacked on it. The front side of the recess is a baffle and the rear side is a support structure. The support structure includes an inclined section and / or a horizontal section. The height of the support structure and the recess decreases from back to front.

[0048] In this embodiment, the support structure is an integral segmented support platform 41 including a horizontal segment 44 and an inclined segment 43. The segmented support platform 41 is installed on the base plate 31, and the space between the segmented support platform 41 and the baffle 34 forms a recessed portion 42.

[0049] Based on the above structure, the hopper device and glove blank forming machine provided in this embodiment can solve the problem of excessive curling and messiness caused by the stacking of glove blanks after the wrist edge is locked. Specifically: By providing a recessed portion 42 to accommodate the wrist seam of the glove blank, the extra thickness of the wrist seam (compared to the palm and finger areas) can be compensated, thereby preventing excessive warping and clutter at the wrist area when multiple glove blanks are stacked. Specifically, the horizontal segment 44 of the support structure is used to place the palm area of ​​the glove blank, while the inclined segment 43 is used to raise the finger area of ​​the glove blank to a certain extent, preventing the wrist seam of the glove blank from sliding out of the recessed portion 42 when the positioning component presses down on the finger area. In this embodiment, by providing an integrated segmented support platform 41, the height difference between it and the base plate 31 naturally forms the recessed portion 42. In other embodiments, a downwardly recessed portion 42 can also be further formed on the base plate 31, depending on actual needs.

[0050] In some other embodiments, the support structure may omit the inclined section 43 and retain only the horizontal section 44, depending on actual needs; or, the horizontal section 44 may be omitted and only the inclined section 43 may be provided, as long as the support structure and the recess can form a shape with a decreasing height from back to front.

[0051] Example 4 This embodiment provides a hopper device and a glove blanking machine including the hopper device, which differs from Embodiment 3 in that: Please refer to Figure 10 The front part of the base plate 31 near the baffle 34 is recessed downward to form a recessed portion 42; the horizontal section 44 in the support structure is the non-recessed part of the base plate 31 located behind the recessed portion 42; the inclined section 43 in the support structure is provided by an inclined platform 45 mounted on the base plate 31, the inclined platform 45 is located behind the horizontal section 44, and the inclined platform 45 forms an inclined surface with a height decreasing from back to front.

[0052] Based on this, by creating a recess 42 on the base plate 31, the base plate 31 itself can serve as a horizontal segment 44, so there is no need to set up an additional horizontal segment 44 structure. Only an inclined platform 45 as an inclined segment 43 needs to be set up.

[0053] In other embodiments, the tilting platform 45 may be omitted as needed, and only the horizontal section 44 formed by the non-recessed portion of the base plate 31 may be retained; or, the front end of the tilting platform 45 may be placed on the base plate 31 behind the recessed portion 42, so that the front end of the tilting platform 45 is adjacent to the recessed portion 42, and the horizontal section 44 formed by the non-recessed portion of the base plate 31 is no longer retained.

[0054] Example 5 This embodiment provides a glove fabrication machine, which has the following further improvements based on Embodiment 1: The hopper device is divided into three horizontally distributed workstations: a dispensing station, a waiting station, and a retrieving station. The hopper device is configured to receive glove blanks that need temporary storage at the dispensing station. The conveying device is configured to retrieve glove blanks from the hopper device at the retrieving station. The waiting station is located between the dispensing and retrieving stations. Please refer to [reference needed]. Figures 11 to 13 In this embodiment, the silo device includes three silo bodies, which are configured to move between a feeding station, a waiting station, and a picking station. Specifically: The three hopper bodies are respectively connected to three hopper drive mechanisms. The three hopper drive mechanisms are each mounted on their respective frames, and then collectively mounted on frame 1 of the blank-setting machine. Specifically: The three main hoppers are designated as Hopper Body 1 (51), Hopper Body 2 (52), and Hopper Body 3 (53), and the three drive mechanisms are designated as Hopper Drive Mechanism 1, Hopper Drive Mechanism 2, and Hopper Drive Mechanism 3. These three drive mechanisms are arranged from top to bottom, with the initial positions of Hopper Body 1 (51), Hopper Body 2 (52), and Hopper Body 3 (53) being the top, middle, and bottom layers, respectively. Furthermore, the three drive mechanisms are staggered and designed to avoid each other.

[0055] Please refer to Figure 14 The hopper drive mechanism includes a translational motion drive sub-mechanism 54. The output end of the translational motion drive sub-mechanism 54 is connected to the hopper body 51. The stroke of the translational motion drive sub-mechanism 54 covers three workstations. Therefore, the hopper drive mechanism can drive the hopper body 51 to perform translational motion at the top layer, so as to realize the switching of the hopper body 51 between the feeding workstation, the waiting workstation and the picking workstation.

[0056] Please refer to Figure 15 and Figure 16 The second hopper drive mechanism includes a second translational motion drive submechanism 55 and a second lifting motion drive submechanism 57. The second lifting motion drive submechanism 57 is connected to the output end of the second translational motion drive submechanism 55, and the output end of the second lifting motion drive submechanism 57 is connected to the second hopper body 52. ​​The stroke of the second translational motion drive submechanism 55 covers 3 workstations, and the stroke of the second lifting motion drive submechanism 57 is one layer upward. Therefore, the second hopper drive mechanism can drive the second hopper body 52 to perform lifting motion between the middle layer and the top layer, and to perform translational motion on the middle layer and the top layer respectively.

[0057] Please refer to Figure 17 and Figure 18 The hopper drive mechanism three includes a translational motion drive submechanism three 56 and a lifting motion drive submechanism three 58. The lifting motion drive submechanism three 58 is connected to the output end of the translational motion drive submechanism three 56. The output end of the lifting motion drive submechanism three 58 is connected to the hopper body three 53. The stroke of the translational motion drive submechanism three 56 covers three workstations, and the stroke of the lifting motion drive submechanism three 58 is two layers upward. Therefore, the hopper drive mechanism three can drive the hopper body three 53 to perform lifting motion between the bottom layer, the middle layer and the top layer, and to perform translational motion on the bottom layer, the middle layer and the top layer respectively.

[0058] Among them, the three translational motion drive sub-mechanisms all use motors, synchronous belts and pulleys, and the two lifting motion drive sub-mechanisms all use two cylinders that are distributed opposite each other on both sides of the hopper (in other embodiments, motor drive can also be selected according to actual conditions).

[0059] Based on the above structure, the glove pre-loading machine provided in this embodiment can address the problem of continuous production being unable to be achieved due to the need to stop the machine for reloading. Specifically, the three main hoppers can simultaneously meet the needs of spare materials of the same specification and pre-loading materials of different specifications, thereby meeting the needs of continuous production.

[0060] Taking specification one glove blanks and specification two glove blanks as examples, assuming that the required quantity of specification one glove blanks needs to be accommodated by 1.2 hopper bodies, and that specification two glove blanks need to be switched after processing specification one glove blanks, the process is set up so that the three hopper bodies are initially in an unloaded state according to... Figure 11 The locations shown are for illustrative purposes only and are not specific limitations. Specifically, silo body one 51 is located at the top material handling station, silo body two 52 is located at the middle waiting station, and silo body three 53 is located at the bottom material discharging station. The three silo bodies can then operate according to the following process: 1) Under the control of the relevant control mechanism, the translational motion drive sub-mechanism 54 drives the hopper body 51 to the uppermost material feeding position, so that the hopper body 51 is fully loaded with a glove blank of specification 1. Then, the hopper body 51 is driven to return to the uppermost material picking position. In order to save standby time, the material conveying device can be started at this time to pick up the material from the hopper body 51. 2) During the process of the material conveying device taking material from the main body of the hopper 51, under the control of the relevant control mechanism, the translational motion drive sub-mechanism 2 55 and the lifting motion drive sub-mechanism 2 57 respectively drive the main body of the hopper 52 to translate and rise, so that the main body of the hopper 52 reaches the uppermost material unloading position; then the main body of the hopper 52 is loaded with the remaining specification one glove blanks, and after the unloading is completed, the translational motion drive sub-mechanism 2 55 drives the main body of the hopper 52 to reset to the middle layer waiting position; 3) Under the control of the relevant control mechanism, the lifting action drive sub-mechanism 358 drives the hopper body 353 to rise to the uppermost material discharge position; then the hopper body 353 is loaded with two-gauge glove blanks. After the material discharge is completed, the lifting action drive sub-mechanism 358 drives the hopper body 353 to return to the lowermost material discharge position. 4) After the glove blanks of specification one on the main body of the hopper 51 are taken out, the translational motion drive sub-mechanism 54 drives the main body of the hopper 51 to translate to the uppermost material feeding position. At the same time / then the translational motion drive sub-mechanism 55 and the lifting motion drive sub-mechanism 57 drive the main body of the hopper 52 to translate and rise in turn, so that the main body of the hopper 52 reaches the uppermost material feeding position. Then the material conveying device continues to take out the gloves of specification one from the main body of the hopper 52, and the main body of the hopper 51 can be reloaded with the glove blanks of the required specification at the uppermost material feeding position. 5) After the specification one glove blanks on the main body of the silo 2 52 are all taken out, the translational motion drive sub-mechanism 2 55 drives the main body of the silo 2 52 to move to the uppermost waiting position. At the same time, the translational motion drive sub-mechanism 3 56 and the lifting motion drive sub-mechanism 3 58 drive the main body of the silo 3 53 to move and rise in turn, so that the main body of the silo 3 53 reaches the uppermost material taking position. Then the material conveying device can take out the specification two gloves from the main body of the silo 3 53. 6) Based on actual production needs, continue to control the actions of the three silo main bodies according to the above logic.

[0061] As can be seen from the above steps, even under relatively extreme conditions, this blank-making machine can ensure high-efficiency and continuous production of the hopper device through the coordinated operation of the three hopper bodies. Specifically, for the number of Grade 1 glove blanks that require 1.2 hopper bodies to hold, if the existing 2-hopper body scheme is adopted, after the first hopper body is filled with Grade 1 glove blanks, the second hopper body only needs to load a very small number of Grade 1 glove blanks. Therefore, the material handling speed of the second hopper body can be very fast, so there is not enough time for the first hopper body to load Grade 2 gloves, and thus it is impossible to achieve a rapid response to Grade 2 gloves, resulting in the need to stop the machine for material loading.

[0062] Example 6 This embodiment provides a glove fabrication machine, which has the following further improvements based on Embodiment 1: An alignment device is installed in the process preceding the die-fitting device. Please refer to [reference needed]. Figures 19 to 21 The alignment device includes a sorting platform 61, an alignment baffle 64, a flipping drive mechanism 63, an opening and closing drive mechanism, and several limiting partitions 62, specifically: Alignment baffle 64 is connected to the front side of sorting platform 61. Flip drive mechanism 63 is located at one end of sorting platform 61 and the output end of flip drive mechanism 63 is connected to sorting platform 61. Several limiting baffles 62 form multiple alignment positions in pairs and multiple alignment positions are arranged side by side on sorting platform 61.

[0063] The limiting partition 62 is provided with a bend, which divides the limiting partition 62 into a parallel section 65 and an opening section 66. The parallel section 65 is perpendicular to the alignment baffle 64 and adjacent to the alignment baffle 64. The opening section 66 is located on the side of the parallel section 65 away from the alignment baffle 64. The two limiting partitions 62 in each group are arranged opposite each other. The parallel sections 65 of the two limiting partitions 62 are parallel to each other, and the opening sections 66 are arranged in a figure-eight shape.

[0064] The output end of the opening and closing drive mechanism is connected to several limiting partitions 62. Specifically, each limiting partition 62 has a connecting block 68 connected to its bottom. The connecting block 68 is connected to the output end of the opening and closing drive mechanism. The opening and closing drive mechanism is configured to drive two limiting partitions 62 in each group to move synchronously towards or away from each other. In this embodiment, the opening and closing drive mechanism uses a drive motor 67, gears, and racks 69 (in other embodiments, belt assemblies, linear sliding modules, etc. may also be used). The two limiting partitions 62 in each group are connected to the rack 69 parts with opposite directions of movement via connecting blocks 68. Several sliding grooves 610 are provided on the sorting platform 61. The opening position and size of the sliding grooves 610 correspond to the several connecting blocks 68. The connecting blocks 68 slide within the sliding grooves 610 under the drive of the opening and closing drive mechanism.

[0065] In other embodiments, the slide groove 610 may be omitted depending on the actual situation. Instead, a through groove may be opened on the front end of the parallel section 65 of the limiting partition 62, so that several limiting partitions 62 are slidably sleeved on the alignment baffle 64 through the through groove. The bottom of the front end of the parallel section 65 where the through groove is located is connected to the connecting structure. Two limiting partitions 62 in each group are respectively connected to the rack 69 parts with opposite directions of movement through the connecting structure.

[0066] Based on the above structure, the glove preform assembly machine provided in this embodiment can address the problem of unsatisfactory alignment of glove preforms. Specifically: The feeding device places the glove blank onto the alignment position on the sorting platform 61. Then, the flipping drive mechanism 63 controls the sorting platform 61 to tilt towards the side where the alignment baffle 64 is located, so that the glove blank slides down and achieves the alignment effect under the obstruction of the alignment baffle 64. To achieve a better alignment effect, in this embodiment, the sorting platform 61 is set to tilt twice continuously (in other embodiments, if it does not affect the production cycle, it can be designed to tilt several times). That is, after the first tilt, when the flipping drive mechanism 63 controls the sorting platform 61 to return to a horizontal or near-horizontal state, the second tilt is then performed. Before each tilt is completed, the acceleration can be increased so that the sorting platform 61 stops quickly to achieve a better alignment effect.

[0067] Furthermore, during the tilting process or after the tilting alignment action is completed, the opening and closing drive mechanism controls the two limiting partitions 62 to move synchronously against each other to achieve the centering positioning of the glove blank. After the two tilting actions are completed, the sorting platform 61 returns to a horizontal state so that the material conveying device can take away the glove blank; after the material conveying device completes the material taking operation, the flipping drive mechanism 63 controls the sorting platform 61 to tilt to the opposite side of the side where the alignment baffle 64 is located, so that the remaining glove blank slides off, thereby avoiding affecting the subsequent glove blanks.
