Description

Technical Field

[0001] The utility model relates to the technical field of glove production equipment, in particular to a glove rejecting device. Background Art

[0002] In the production process of disposable gloves, defective gloves should be detected and rejected before entering the packaging stage. In the prior art, visual inspection devices are usually used to identify and detect defective gloves, but there is a lack of more reasonable rejection devices.

[0003] Specifically, the traditional way to remove defective gloves is manual operation, but this method has the problems of low work efficiency, difficult to ensure the accuracy of removal, and high labor costs; even though some mechanized removal devices have gradually appeared on the market, there are still problems such as poor removal effect, low removal accuracy, and complex structure. For example, the Chinese patent with announcement number CN218691742U provides an air blowing removal device for nitrile medical gloves, which includes multiple blowing nozzles arranged along the moving direction of the hand model on the production line, and uses different heights for blowing, so that the gloves on the hand model gradually move down and fall off; in this patent, the gloves are gradually removed by blowing multiple times, which is easily affected by the angle and firmness of the gloves on the hand model, and thus the removal effect cannot be guaranteed, and the process is complicated and the operation cost (referring to time cost, device operation cost, etc.) is high. Another glove needs to be set with multiple blowing nozzles, which makes the equipment structure complex and costly, and also increases the probability of equipment failure. Utility Model Content

[0004] The utility model aims to provide a glove rejecting device to solve the problem in the prior art that both the manual rejecting method and the rejecting device have limitations in effect and cost, resulting in a lack of a more reasonable glove rejecting device.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] A glove rejection device comprises a frame, a clamping mechanism, a material box and a power mechanism. The frame is provided with a clamping mechanism, a material box is provided at a corresponding position below the clamping mechanism, the clamping mechanism is driven by a power mechanism, and the clamping mechanism forms a circulation channel during clamping intervals.

[0007] In the utility model, by setting a clamping mechanism, the defective gloves detected by the visual inspection device can be clamped, and the clamped defective gloves fall into the material box, thereby completing the removal of the defective gloves; wherein the clamping mechanism is driven by a power mechanism and does not require manual intervention.

[0008] Furthermore, the clamping mechanism includes a mounting frame, a clamping assembly and a transmission assembly. The mounting frame is U-shaped, is installed on a frame body and is provided with a clamping assembly. The clamping assembly includes two circular rollers with recessed portions, the recessed portions of the two circular rollers are symmetrically arranged, and the two circular rollers are respectively connected to the transmission assemblies.

[0009] In the above scheme, under the simultaneous action of the two sets of transmission components, the two circular rollers can be rotated inward or outward at the same time, thereby completing the clamping action or releasing action of the defective gloves; the defective gloves are removed from the hand mold by the clamping action, and the removed defective gloves fall into the material box by the releasing action.

[0010] Furthermore, the transmission assembly includes two rotating shafts, which are coaxially fixedly connected to two circular rollers respectively; the two ends of each rotating shaft are connected to the mounting frame through bearings respectively, and the bearings are fixedly arranged on the U-shaped side wall of the mounting frame; one end of the rotating shaft extends out of the mounting frame and a synchronous pulley I is arranged at the end of the end.

[0011] In the above scheme, the rotation of the synchronous pulley I can drive the rotating shaft to rotate, and then drive the circular roller to rotate.

[0012] Furthermore, the power mechanism includes a motor arranged below the synchronous pulley I, and the output shaft of the motor is respectively connected to the two synchronous pulleys I through a changing assembly; the changing assembly includes two synchronous pulleys II and two synchronous belts, the two synchronous pulleys II are arranged and installed on the output shaft of the motor, and the two synchronous pulleys II are respectively located below the two synchronous pulleys I, one of the synchronous belts is twisted 90° in the clockwise direction and then connected between a group of synchronous pulleys II and synchronous pulley I distributed up and down, and the other synchronous belt is twisted 90° in the counterclockwise direction and then connected between another group of synchronous pulleys II and synchronous pulley I distributed up and down.

[0013] In the above scheme, the synchronous pulley I can be driven by the motor and the direction-changing component, and then the circular roller can be driven; because the rotating surface of the synchronous pulley I and the rotating surface of the output shaft of the motor are perpendicular to each other, it is necessary to set a direction-changing component so that the output shaft of the motor can drive the synchronous pulley I to rotate, specifically: the synchronous pulley II can drive the belt to rotate along the rotating surface of the output shaft of the motor, but after twisting the belt 90°, the rotation direction can be changed and the synchronous pulley I can be successfully driven to rotate; the two twisting directions (i.e. clockwise and counterclockwise) are to respectively adapt to two symmetrically arranged circular rollers.

[0014] Furthermore, a material box channel is provided between the clamping mechanism and the material box.

[0015] In the above solution, by providing a material box channel, defective gloves can fall into the material box more accurately.

[0016] Furthermore, a plurality of clamping mechanisms are arranged on the frame, corresponding material boxes are respectively arranged below the plurality of clamping mechanisms, and the plurality of clamping mechanisms are respectively driven by corresponding power mechanisms; and the height positions of the plurality of clamping mechanisms are consistent or inconsistent.

[0017] In the above scheme, by setting more than one clamping mechanism, the rejection work can be carried out in parallel on multiple lines, thereby effectively improving the rejection efficiency of the device. In practical applications, due to factors such as different sagging heights of gloves when multiple lines are in parallel, the sagging heights of defective gloves on each rejection line are different, so the height positions of multiple clamping mechanisms can be set differently to improve the applicability of the device.

[0018] Furthermore, a rejection trigger detection device is provided on a mounting frame on one side of the two circular rollers, and the rejection trigger detection device is connected to the motor signal.

[0019] In the above scheme, a rejection trigger detection device is provided to trigger the action of the two circular rollers, thereby avoiding continuous action of the circular rollers and related components, and further effectively improving the service life of the device. Specifically: in the production line, when a defective glove passes through the rejection device, it will first pass through the rejection trigger detection device on the rejection device. Therefore, when the rejection trigger detection device has a signal, it means that the defective glove is about to reach the rejection device, and the defective glove is not undemolded or demolded too short (if it belongs to these two cases, the lowest height of the defective glove will be higher than the maximum detection height of the rejection trigger detection device, resulting in the rejection trigger detection device being unable to detect it). Therefore, in this case, the action of the rejection device is not an invalid action, and the rejection trigger detection device will start the motor, thereby driving the two circular rollers to rotate inward at the same time to clamp the defective glove.

[0020] Furthermore, a rejection confirmation detection device is provided on a mounting frame on one side of the two circular rollers, and a material falling detection device is provided on the upper end of the material box or on the upper inner surface of the material box.

[0021] In the above scheme, a rejection confirmation detection device and a material drop detection device are provided to detect whether the defective gloves are successfully rejected, so that the corresponding information can be transmitted to the subsequent process in time, and data can be provided to reflect the current demoulding quality of the gloves and the rejection effect of the defective gloves, so that the subsequent equipment can perform the corresponding rejection process or guide the staff to adjust the relevant equipment or production process in time. Specifically: in the production line, when the defective gloves are about to leave the rejection device, they will pass through the rejection confirmation detection device on the rejection device; if the defective gloves are removed from the hand mold by two circular rollers, the hand mold without defective gloves moves to the rejection confirmation detection device, and the lowest height of the hand mold is higher than the highest detection height of the rejection confirmation detection device, so the rejection confirmation detection device has no signal; and, since the defective gloves will fall into the material box after being removed, the material drop detection device has a signal. On the contrary, if the defective glove is not removed from the hand mold or the defective glove is torn by the two circular rollers but a large part remains on the hand mold, that is, the defective glove is not successfully removed, then the rejection confirmation detection device has a signal; in this case, if the material falling detection device has no signal, it means that nothing falls into the material box, and further, it means that the defective glove is not removed from the hand mold at all; if the material falling detection device has a signal, it means that something falls into the material box, and further, it means that the defective glove is torn so that only a part of the defective glove falls into the material box.

[0022] Furthermore, the material falling detection device is signal-connected to a material full alarm device.

[0023] In the above scheme, by arranging a material drop detection device and a material full alarm device, it is possible to detect whether the material box is full and remind the staff to clean it in time to avoid defective gloves overflowing from the material box or even winding around the circular roller and causing the device to get stuck. Specifically: since the material drop detection device is arranged at the upper end of the material box or the upper inner surface of the material box, if the material drop detection device continues to have a signal, it means that the defective gloves in the material box have accumulated to the upper part. In this case, the material drop detection device will link the material full alarm device to alarm.

[0024] The beneficial effects achieved by the utility model are:

[0025] Provided is a glove rejection device, which can automatically clamp and collect defective gloves by setting a frame, a clamping mechanism, a material box and a power mechanism, thereby completing the rejection of defective gloves. Compared with the traditional manual operation method, the utility model can greatly save labor costs, has high work efficiency, and can guarantee the rejection accuracy to a considerable extent; compared with the rejection device in the prior art, the utility model can clamp defective gloves and then reject them by setting two circular rollers, and only needs to act once for each defective glove, and has the advantages of simple process, low operation cost, good rejection effect, high accuracy, and the simple structure of the device makes the cost low.

[0026] In addition, the glove rejection device provided by the utility model is also provided with a rejection trigger detection device, a rejection confirmation detection device and a material drop detection device; the rejection trigger detection device can reduce the invalid actions of the rejection device, thereby effectively improving the life of the device; the rejection confirmation detection device and the material drop detection device can detect whether the defective gloves are successfully rejected, which helps to timely link the subsequent processes and provide relevant data for corresponding production adjustments; the material drop detection device is combined with the full material alarm device to remind the staff to clean up the full material box in time to avoid adverse effects on production.

DETAILED DESCRIPTION

[0032] To clearly illustrate the solution in the utility model, further description is given below in conjunction with the accompanying drawings:

[0033] Example 1

[0034] This embodiment provides a glove rejection device, which is used to reject defective gloves detected by a visual inspection device, specifically:

[0035] Please refer to Figure 1 and Figure 3The device in this embodiment includes a frame 1, and four (in other embodiments, other numbers can be set according to actual needs) clamping mechanisms are arranged on the frame 1, and the height of the two clamping mechanisms located on both sides is higher than the height of the two clamping mechanisms located in the middle (in other embodiments, other height distinction methods can be set according to actual needs); corresponding material box channels 3 are respectively provided under the four clamping mechanisms, and corresponding material boxes 2 are respectively provided under each material box channel 3, and four material boxes 2 are arranged at the bottom of the frame 1; each clamping mechanism is driven by a corresponding power mechanism, and the four power mechanisms are arranged on one side or both sides of the frame 1 (the specific side of the frame 1 on which the power mechanism is set can be set according to actual needs), and the clamping mechanism forms a circulation channel during the clamping interval.

[0036] Please refer to Figure 2 , taking a clamping mechanism and a power mechanism as an example, the specific structure is as follows:

[0037] The clamping mechanism includes a mounting frame, a clamping assembly and a transmission assembly; the mounting frame is U-shaped, the mounting frame is mounted on the frame body 1 and the clamping assembly is provided on the mounting frame, the clamping assembly includes two circular rollers 4 with recessed parts, the recessed parts of the two circular rollers 4 are symmetrically arranged, and a reserved gap 10 for defective gloves to pass through is provided between the two circular rollers 4; the two circular rollers 4 are respectively connected to a set of transmission assemblies. The transmission assembly includes two rotating shafts 5, the two rotating shafts 5 are respectively coaxially fixedly connected to the two circular rollers 4, and the two ends of each rotating shaft 5 are respectively connected to the mounting frame through bearings, and the bearings are fixedly arranged on the U-shaped side wall of the mounting frame, one end of the rotating shaft extends out of the mounting frame and a synchronous pulley Ⅰ6 is arranged at the end of the end.

[0038] The power mechanism includes a motor 9 arranged below two synchronous pulleys Ⅰ6, the rotation axis of the output shaft of the motor 9 is perpendicular to the rotation axis of the synchronous pulley Ⅰ6, and the output shaft of the motor 9 is connected to the two synchronous pulleys Ⅰ6 through a direction-changing assembly. The direction-changing assembly includes two synchronous pulleys Ⅱ8 and two synchronous belts 7; the two synchronous pulleys Ⅱ8 are arranged and installed on the output shaft of the motor 9, and the two synchronous pulleys Ⅱ8 are axially perpendicular to the two synchronous pulleys Ⅰ6, and the two synchronous belts 7 are twisted 90° in the clockwise direction and counterclockwise direction respectively and then connected between the corresponding perpendicular synchronous pulleys Ⅱ8 and synchronous pulleys Ⅰ6.

[0039] Based on the above structure, the working principle of this embodiment is as follows:

[0040] When the defective gloves detected by the visual inspection device reach the rejection device via the transport line, the motor 9 will start working, so that the output shaft of the motor 9 drives the two synchronous pulleys Ⅱ8 to rotate synchronously. Through the transmission of the synchronous belt 7, the two synchronous pulleys Ⅰ6 rotate synchronously and in the opposite direction. The rotation of the two synchronous pulleys Ⅰ6 can drive the two rotating shafts 5 to rotate synchronously and in the opposite direction, thereby causing the two circular rollers 4 to rotate clockwise and counterclockwise respectively, so that the two circular rollers 4 form a tendency to approach each other, thereby clamping the defective gloves that reach the circular rollers 4, that is, removing the defective gloves from the hand model. After clamping is completed, the motor 9 works in the opposite direction, causing the two circular rollers 4 to rotate counterclockwise and clockwise respectively, so that the two circular rollers 4 form a tendency to separate, thereby releasing the clamped defective gloves. Please refer to Figure 3 After being released, the defective gloves will fall into the material box 2 through the material box channel 3, thus completing the removal and collection of the defective gloves. The four sets of gripping mechanisms, the material box channel 3, the power mechanism and the material box 2 in this embodiment can work independently, thereby achieving the production effect of multiple production lines in parallel.

[0041] In summary, the glove rejection device provided in this embodiment can automatically clamp and collect defective gloves, thereby completing the rejection of defective gloves. It has high working efficiency and can ensure the rejection accuracy to a considerable extent. It also has the advantages of simple process, low operating cost and good rejection effect.

[0042] Example 2

[0043] This embodiment provides a glove rejection device. On the basis of Embodiment 1, the device is further provided with a rejection trigger detection device 11, a rejection confirmation detection device 12, a material falling detection device and a material full alarm device. Specifically:

[0044] In this embodiment, the rejection trigger detection device 11, the rejection confirmation detection device 12, and the material falling detection device all use photoelectric switches (in other embodiments, other electronic devices can be selected according to actual conditions as long as they can achieve the detection function).

[0045] Please refer to Figure 4, a rejection trigger detection device 11 is provided on the mounting frame of the two circular rollers 4 on the side away from the synchronous pulley Ⅰ6 (in other embodiments, the rejection trigger detection device 11 can be installed at other positions according to actual conditions, so that the defective gloves will first pass through the rejection trigger detection device on the rejection device when passing through the rejection device), and the rejection trigger detection device 11 is connected to the motor 9 signal; a rejection confirmation detection device 12 is provided on the mounting frame of the two circular rollers 4 on the side close to the synchronous pulley Ⅰ6 (in other embodiments, the rejection confirmation detection device 12 can be installed at other positions according to actual conditions, so that the defective gloves will pass through the rejection confirmation detection device on the rejection device when they are about to leave the rejection device). In addition, a material drop detection device is provided on the upper part of the inner surface of the material box 2 (not shown in the figure, in other embodiments, the material drop detection device can also be set at the upper end of the material box 2 or on the frame 1 at a height higher than the material box 2), and the material drop detection device is connected to the material full alarm device signal, and the material full alarm device is set on the frame 1 (not shown in the figure, in other embodiments, the material full alarm device can also be set at other suitable positions).

[0046] Based on the above structure, the working principle of this embodiment is as follows:

[0047] Ⅰ. The rejection trigger detection device 11 is used to trigger the action of the two circular rollers 4.

[0048] When the defective gloves detected by the visual inspection device pass through the rejection trigger detection device 11, the rejection trigger detection device has a signal, indicating that the defective gloves are about to reach the rejection device, and the defective gloves are not un-demolded or demolded too short. In this case, the action of the rejection device is not an invalid action, and the rejection trigger detection device 11 will start the motor 9, thereby driving the two circular rollers 4 to rotate inward at the same time to clamp the defective gloves.

[0049] This can avoid continuous movement of the circular roller 4 and related components, reduce ineffective movement of the rejection device, and effectively increase the service life of the device.

[0050] II. The rejection confirmation detection device 12 and the material drop detection device are used to detect whether the defective gloves are successfully rejected.

[0051] The rejection confirmation detection device 12 has no signal, and the material falling detection device has a signal: it means that the defective glove is taken off the hand mold by the two circular rollers 4 and falls into the material box 2, which means that the defective glove is successfully rejected;

[0052] The rejection confirmation detection device 12 has a signal, and the material drop detection device has no signal: it means that the defective glove has not been successfully removed and nothing has fallen into the material box 2, which further means that the defective glove has not been removed from the hand model at all;

[0053] The rejection confirmation detection device 12 has a signal and the material falling detection device has a signal: it means that the defective glove is not successfully removed but something falls into the material box 2, which further means that the defective glove is torn so that only a part of the defective glove falls into the material box 2.

[0054] In this way, the corresponding information can be transmitted to the subsequent process in a timely manner, and data can be provided to reflect the current demoulding quality of gloves and the removal effect of defective gloves, so as to guide the staff to adjust the relevant equipment or production process in a timely manner.

[0055] III. The material drop detection device and the material full alarm device are used to detect whether the material box 2 is full and issue an alarm prompt.

[0056] Since the material drop detection device is arranged on the upper inner surface of the material box 2, if the material drop detection device continuously sends a signal, it means that the defective gloves in the material box 2 have accumulated to the upper part. In this case, the material drop detection device will link the material full alarm device to alarm, so as to remind the staff to clean up in time.

[0057] This can prevent defective gloves from overflowing from the material box 2 or even being wound around the circular roller 4, causing the device to get stuck, thereby avoiding adverse effects on production.

[0058] It should be noted that the parts that are not described in detail or in detail in the above scheme are all existing technologies, such as the signal control principle of the motor, the electrical connection principle between the material drop detection device and the alarm, etc., which do not belong to the improvements made by the present invention on the existing technology, nor do they belong to the protection scope of the technical scheme of the present invention, so they will not be repeated in this article.

[0059] Of course, the above contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of the embodiments of the present invention. The present invention is not limited to the above examples, and any equivalent changes and improvements made by ordinary technicians in the technical field within the essential scope of the present invention shall fall within the scope of the patent coverage of the present invention.
