Description

Technical Field

[0001] This utility model relates to the field of glove production and packaging technology, specifically to a glove roller pick-and-follow device. Background Technology

[0002] In modern glove production lines, automated pick-up devices are one of the key components ensuring efficient production and product quality. Traditional roller pick-up devices typically consist of two opposing pick-up rollers and a drive mechanism, used to remove gloves from the mold by clamping and rotating them.

[0003] For example, CN 211768827U discloses a gripper-type glove transfer and stacking device. The disclosed picking and transferring device includes picking rollers and a picking conveyor belt. The picking conveyor belt is horizontally arranged, and its output end is connected to the input end of a guiding device. Picking rollers are arranged in pairs, horizontally positioned above the picking conveyor belt, with their axes perpendicular to the conveying direction of the belt. The picking conveyor belt works in conjunction to stack the picked gloves onto it. Each pair of picking rollers is connected to a picking motor that drives its rotation. The two picking rollers in each pair rotate synchronously in opposite directions, thereby removing the gloves from the hand mold. However, in practical applications, the glove production line operates at a high speed to the picking rollers, where the gloves are gripped and removed. Due to the high speed of the production line, the removed gloves may shift due to inertia. Although guide plates are provided, and the width of the conveyor trough gradually narrows to correct for the glove shifting problem caused by inertia. However, for flexible products such as gloves, the gloves may bend and stack due to the gradually narrowing width of the conveyor trough and the limitations of the guide plate, rather than angular offset correction. Therefore, the above settings are not applicable to the angle correction problem after gloves and other flexible products are removed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a glove roller picking follow-up device.

[0005] The technical solution adopted by this application to solve its technical problem is as follows: the glove roller picking follow-up device includes a picking mechanism, the picking mechanism includes two picking rollers arranged opposite each other, the two ends of the picking rollers are respectively rotatably connected to the support base, one end of the picking roller is driven by a driving mechanism, the driving mechanism is used to drive the two picking rollers to rotate relative to each other, and also includes a translation device for driving the picking rollers to translate, the translation direction of the picking rollers is perpendicular to the rotation direction of the picking rollers.

[0006] This application adds a translation device to the existing glove roller picking device, which controls the translation of the picking roller. Before the gloves are conveyed to the designated picking station on the glove production line, the translation device moves the picking roller forward a certain distance, aligning it with the gloves in advance. Simultaneously, the picking roller moves backward and resets on the glove production line while gripping the gloves. When it resets to the designated picking station, the glove picking operation is completed. Therefore, the glove angle is corrected simultaneously during glove picking, preventing the picked gloves from shifting due to inertia.

[0007] The driving mechanism includes a drive motor, the output shaft of which is coaxially and fixedly connected to one end of a main shaft, and the main shaft is respectively connected to one end of each of the two picking rollers.

[0008] The translation device includes a fixed guide rail, the support base moves back and forth along the guide rail, and the guide rail is arranged parallel to the picking roller;

[0009] It also includes a transmission mechanism that drives the support base to move back and forth along the guide rail.

[0010] The device includes a fixedly mounted transmission motor, which is connected to a transmission gear. A rack is fixedly mounted on the support base, and the transmission gear meshes with the rack.

[0011] As an alternative, the translation device includes a translation shaft, which is arranged parallel to the picking roller and is drively connected to the main shaft;

[0012] The surface of the translation shaft is provided with a guide groove, and a positioning column is fixedly provided on the support base. The positioning column is adapted to the guide groove. When the translation shaft rotates through the main shaft drive, the positioning column drives the support base to translate under the guidance of the guide groove.

[0013] It also includes a reset element, which provides a force opposite to the direction of translation of the support, so that the support can be reset.

[0014] The guide groove includes a straight groove and a curved groove. The straight groove is parallel to the central axis of the translation shaft. One end of the curved groove is connected to one end of the straight groove. The other end of the curved groove rotates along the outer circumferential surface of the translation shaft until it connects with the other end of the straight groove to form a closed loop groove.

[0015] The curved groove is a threaded groove.

[0016] It also includes a fixed guide rail, which is parallel to the picking roller, and the support base moves back and forth along the guide rail;

[0017] The translation pivot is located on one side of the support base. The reset component includes a spring, which is sleeved on the guide rail. One end of the spring is connected to the guide rail, and the other end of the spring is connected to the support base.

[0018] The other end of the main shaft is connected to one end of the translation shaft via a gear set. Specifically, a bevel gear is coaxially fixedly connected to the other end of the main shaft, and another bevel gear is coaxially fixedly connected to one end of the translation shaft; the two bevel gears mesh.

[0019] As an alternative, the picking roller includes a roller sleeve and a roller shaft, the roller sleeve and the roller shaft are slidably connected coaxially, the two ends of the roller shaft are respectively rotatably connected to the support base, and one end of the roller shaft is connected to the drive mechanism for transmission.

[0020] The translation shaft is sleeved on the roller shaft, and one end of the translation shaft is coaxially and fixedly connected to the roller sleeve. The translation shaft and the roller shaft are also coaxially and slidably connected.

[0021] The reset component includes a spring, with one end of the roller sleeve connected to one end of the spring. The spring is sleeved on the roller shaft, and the other end of the spring is connected to the support base.

[0022] Compared with the prior art, this application has the following advantages: This application uses a translation device to translate the picking roller a certain distance, and its translation direction is opposite to the direction of the glove's movement along the glove production line, allowing for pre-connection with the glove and improving the accuracy of picking. As the glove moves with the glove production line to the set picking station, the picking operation is completed synchronously during the synchronous backward movement of the picking roller. When the glove is picked, the picking roller and the glove are relatively stationary, that is, the glove angle is corrected at the same time as the glove is picked, avoiding the glove from shifting due to inertia and ensuring the correct glove picking angle.

[0023] Meanwhile, the glove removal operation is completed simultaneously during the synchronous backward movement of the removal roller, which reduces the time the glove production line spends at the set removal station, supports continuous operation, and also shortens the time of each glove removal operation, thus improving glove removal efficiency.

[0024] Meanwhile, through reasonable mechanical design, this application achieves the transmission of all mechanisms that can be controlled by only one power source, which significantly reduces manufacturing and maintenance costs. Attached Figure Description

[0038] Example 1

[0039] A glove roller picking follow-up device includes a picking mechanism, which includes two picking rollers 1 arranged opposite to each other. Each end of the picking roller 1 is rotatably connected to a support base 3. One end of the picking roller 1 is driven by a drive mechanism 2, which drives the two picking rollers 1 to rotate relative to each other. The device also includes a translation device for driving the picking rollers 1 to translate, wherein the translation direction of the picking roller 1 is perpendicular to the rotation direction of the picking roller 1.

[0040] The driving mechanism 2 includes a drive motor 201, the output shaft of which is coaxially and fixedly connected to one end of a main shaft 202, and the main shaft 202 is respectively connected to one end of the two picking rollers 1.

[0041] In this embodiment, there is no improvement to the picking roller 1. The roller sleeve 101 and roller shaft 102 of the picking roller 1 are coaxially fixedly connected. Both ends of the roller shaft 102 are rotatably connected to the corresponding support seats 3 via bearings. One end of each of the two roller shafts 102 extends out of the corresponding support seats 3 and is coaxially fixedly connected to a pulley. The pulleys are respectively connected to the main shaft 202 via belts 203 or chains. Depending on the type of belt 203 or chain selected, the pulley can be a corresponding pulley or chain wheel.

[0042] For the relative rotation of the picking roller 1 via a main shaft 202, refer to the torsion glove picking device disclosed in announcement number CN220898029U, which will not be described in detail here.

[0043] Reference Figure 1 and Figure 2 In this embodiment, the translation device includes a fixed guide rail 5, the support base 3 moves back and forth along the guide rail 5, and the guide rail 5 is arranged parallel to the picking roller 1;

[0044] It also includes a transmission mechanism that drives the support base 3 to move back and forth along the guide rail 5.

[0045] The transmission mechanism includes a fixedly mounted transmission motor 6 located below the support base 3. The transmission motor 6 is connected to a transmission gear 7, and a rack 8 is fixedly mounted on the support base 3. The transmission gear 7 meshes with the rack 8. Alternatively, existing pulley structures or linear modules can be used to achieve the transmission and translation drive.

[0046] Example 2

[0047] Reference Figure 3 and Figure 4 The difference from Embodiment 1 is that the translation device in this embodiment includes a translation shaft 9, which is arranged parallel to the picking roller 1;

[0048] The surface of the translation shaft 9 is provided with a guide groove 12, and a positioning column 11 is fixedly provided on the support base 3. The positioning column 11 is adapted to the guide groove 12. When the translation shaft 9 is rotated by the main shaft 202, the positioning column 11 drives the support base 3 to translate along the guide rail 5 under the guidance of the guide groove 12.

[0049] It also includes a reset element, which provides a force opposite to the direction of movement of the support 3 when guided by the guide groove 12, so that the support 3 can be reset.

[0050] Reference Figure 4 , Figure 8 and Figure 9 The guide groove 12 includes a straight groove and a curved groove. The straight groove is parallel to the central axis of the translation shaft 9. One end of the curved groove is connected to one end of the straight groove, and the other end of the curved groove rotates along the outer circumferential surface of the translation shaft 9 until it connects with the other end of the straight groove to form a closed-loop groove. Further, the curved groove can be configured as a threaded groove.

[0051] The reset component includes a spring 4. This embodiment retains the guide rail 5 configuration from embodiment 1. The support base 3 is slidably connected to the guide rail 5 and can move back and forth along the guide rail 5. The translation shaft 9 is located on one side of the support base 3. The spring 4 is sleeved on the guide rail 5. One end of the spring 4 is fixedly connected to the guide rail 5, and the other end of the spring 4 is fixedly connected to the support base 3 (the spring 4 is not shown in this embodiment).

[0052] In this embodiment, for the sake of the stability of the translation shaft 9, fixing plates 10 are provided at both ends of the translation shaft 9. The fixing plates 10 are fixedly installed, and both ends of the translation shaft 9 are rotatably connected to the fixing plates 10 respectively. One end of the translation shaft 9 passes through one of the fixing plates 10 and is connected to the main shaft 202 for transmission.

[0053] The other end of the main shaft 202 is connected to one end of the translation shaft 9 via a gear set. Specifically, refer to... Figure 3A bevel gear is coaxially fixedly connected to the other end of the main shaft 202, and another bevel gear is coaxially fixedly connected to one end of the translation shaft 9. The two bevel gears mesh. Thus, only one drive source is needed to control both the translation and relative rotation of the picking roller 1, saving costs.

[0054] Corresponding to the conveying direction of the glove production line relative to the straight trough, the two ends of the straight trough can be defined as the input end and the output end, respectively. In this embodiment, when the positioning column 11 is located at the input end of the straight trough, the spring is in a compressed state. Based on the spring force, the support seat 3 moves forward along the guide rail 5, and the picking roller 1 moves forward accordingly, simultaneously driving the positioning column 11 to the output end of the straight trough. Subsequently, based on the rotation of the translation shaft 9, the positioning column 11 moves again along the curved trough to the input end of the straight trough. During this process, the support seat 3 moves backward along the guide rail 5, and the spring is gradually compressed. This process is repeated, causing the support seat 3 to move back and forth along the guide rail 5 within the length range of the straight trough. The picking roller 1 can also move forward a certain distance before the glove reaches the set picking position, and move backward synchronously with the glove production line while gripping the glove. When it reaches the set picking position, the glove picking operation is completed simultaneously. Therefore, the removed glove will not be offset due to inertia caused by the high conveying speed of the glove production line, ensuring the neatness of the removed gloves.

[0055] The position of the drive mechanism 2 relative to the support base 3 and the position of the transmission mechanism can be adjusted according to the actual situation to ensure that the spring 4 is in a compressed state when the picking roller 1 is located at the set picking position.

[0056] Example 3

[0057] Reference Figures 5-7 The difference between this embodiment and Embodiments 1 and 2 lies in the improvement of the structure of the picking roller 1 and the translation device. Specifically, in this embodiment, the roller sleeve 101 of the picking roller 1 is coaxial with the roller shaft 102 but is not fixed, but can slide relative to it. The two ends of the roller shaft 102 are respectively rotatably connected to the support base 3, and one end of the roller shaft 102 is connected to the drive mechanism 2. The translation shaft 9 is sleeved on the roller shaft 102, and the translation shaft 9 is coaxially and fixedly connected to one end of the roller sleeve 101. The method of coaxial fixed connection is not limited, such as welding, interference fit, key connection, sliding sleeve connection or threaded connection, etc. The translation shaft 9 is coaxially and slidably connected to the roller shaft 102.

[0058] One end of the roller sleeve 101 is fixedly connected to one end of the spring 4, which is sleeved on the roller shaft 102. The other end of the spring 4 is fixedly connected to the support base 3. The two ends of the spring 4 can also be in contact with the roller sleeve 101 and the support base 3 respectively.

[0059] The translation shaft 9 and the roller shaft 102 are coaxially and slidably connected based on an axial guide structure, specifically a spline structure. Further, referring to... Figure 6 In this embodiment, a keyway is provided on the translation shaft 9, and a corresponding spline is provided on the roller shaft 102. This enables the translation shaft 9 and the roller shaft 102 to be coaxial and slide relative to each other. The roller sleeve 101 is coaxially and fixedly connected to the translation shaft 9, thereby enabling the roller sleeve 101 and the roller shaft 102 to be coaxially and slidably connected. The positions of the keyway and the spline can be interchanged, as long as the coaxial sliding connection between the roller sleeve 101 and the translation shaft 9 is achieved.

[0060] This embodiment 3 also achieves the transmission of all mechanisms by setting only one power source, saving costs.

[0061] In this embodiment, the other end of the roller sleeve 101 is located near the drive mechanism 2 (i.e., the spring 4 is located at the end of the roller sleeve 101 near the drive mechanism), and the conveying direction of the glove production line is consistent with the direction from one end of the roller sleeve 101 to the other end of the roller sleeve 101.

[0062] Based on this, when the positioning post 11 is located at the input end of the glove production line in the straight groove, the spring 4 is in a compressed state. The elastic force of the spring 4 causes the output end of the straight groove to move towards the positioning post 11. The roller sleeve 101 moves forward relative to the roller shaft 102. The drive mechanism 2 controls the rotation of the roller shaft 102, driving the translation shaft 9 to rotate. Thus, the positioning post 11 enters the curved groove of the guide groove 12. Due to the relative position of the positioning post 11 and the curved groove, the roller sleeve 101, based on its spline structure, rotates coaxially with the roller shaft 102 while also moving relatively backward. Therefore, the roller sleeve 101 can move back and forth along the roller shaft 102 within the length of the straight groove. The roller sleeve 101 can also move forward a certain distance before the glove reaches the set picking position, and then move backward synchronously with the glove production line. During the backward movement, the two roller sleeves 101 rotate relative to each other to pick up the glove. When the glove reaches the set picking position, the glove picking operation is completed simultaneously. Therefore, the removed gloves will not shift due to inertia caused by the high conveying speed of the glove production line, ensuring the neatness of the removed gloves.

[0063] The positions of the drive mechanism, the direction of the curved groove, the conveying direction of the glove production line, the spring 4, and the guide groove 12 can be set according to the actual situation to ensure that the spring 4 is in a compressed state when the roller sleeve 101 is located at the set picking position.

[0064] Multiple units of this application can be installed side-by-side with the glove production line to increase the continuity of the picking process.

[0065] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
