Description

Technical Field

[0001] This application relates to a winding feeding mechanism. Background Technology

[0002] Reference Figure 1 As shown, some strip products, especially metal strip products, are wound onto a core in coils. A separator paper strip (b) is attached to one side to separate adjacent coils of strip product (a), thus protecting each coil from scratches. When the aforementioned strip product, used as raw material, needs to be released for processing, not only is strip product (a) released, but the separator paper strip (b) is also released simultaneously. If the released separator paper strip (b) is not collected and allowed to fall to the ground, there is a risk of the paper strip getting entangled in the equipment, damaging production, and even causing workplace injuries. Summary of the Invention

[0003] The technical problem to be solved by this application is: to propose a safe and reliable unwinding feeding mechanism that can effectively prevent the free fall of the separator paper tape in response to the above-mentioned problems.

[0004] The technical solution of this application is:

[0005] An unwinding feeding mechanism, comprising:

[0006] Base frame;

[0007] A material tray, rotatably mounted on the base frame, with product tape and separator paper tape wound on the tray; and

[0008] A material conveying assembly, which cooperates with the product material conveyor belt released from the material tray to guide the product material conveyor belt downstream;

[0009] The unwinding and feeding mechanism also includes:

[0010] A paper tape take-up reel, connected to the separating paper tape dispensed from the feed tray, for winding the separating paper tape thereon; and

[0011] A reflective photoelectric sensor, comprising a transmitter and a receiver that cooperate with each other, wherein light emitted by the transmitter is reflected to the receiver after being directed at the separating paper tape between the paper tape take-up reel and the material tray.

[0012] In addition to the above technical solutions, this application also includes the following preferred solutions:

[0013] The paper tape take-up reel is rotatably mounted on the base frame.

[0014] The unwinding and feeding mechanism also includes an alarm connected to the reflective photoelectric sensor circuit.

[0015] The alarm is an audible and visual alarm.

[0016] The reflective photoelectric sensor is mounted on the base frame.

[0017] The reflective photoelectric sensor is arranged on the conveying path of the separating paper tape between the paper tape take-up reel and the material tray.

[0018] The position of the reflective photoelectric sensor on the base frame is adjustable.

[0019] Casters are installed at the bottom of the base frame.

[0020] The casters are swivel casters.

[0021] The unwinding feeding mechanism also includes a belt traction component connected to the product belt released from the material tray to drive the product belt downstream.

[0022] The beneficial effects of this application are:

[0023] 1. The paper tape rewinding reel of the unwinding feeding mechanism of this application is connected to the separating paper tape released from the material tray, thereby winding the separating paper tape released from the material tray during the production process onto it. In addition, the configured reflective photoelectric sensor can monitor whether the paper tape is stably conveyed in real time, eliminating various hidden dangers in terms of production efficiency, production quality and personnel safety caused by the free scattering of the separating paper tape.

[0024] 2. Configure an audible and visual alarm connected to the reflective photoelectric sensor circuit. Once a paper break is detected, the audible and visual alarm will emit an audible and visual alarm signal to promptly alert the staff to take the opposite action.

[0025] 3. Place the reflective photoelectric sensor on the conveying path of the paper tape separating the paper tape between the paper tape reel and the material tray to shorten the optical path and thus reduce the possibility of the optical path being blocked by external objects.

[0026] 4. The mounting position of the reflective photoelectric sensor on the base frame is adjustable to adapt to changes in the angle of the separating paper tape. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

The terms "a" or "an" and similar expressions used in this specification and claims do not indicate a limitation of quantity, but rather indicate the presence of at least one.

[0038] The serial numbers assigned to components in this application specification and claims, such as "first," "second," etc., are merely for distinguishing the described objects and have no sequential or technical meaning. Furthermore, the terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages). The term "multiple" in this application indicates at least two.

[0039] In the description of this application and the claims, the terms "upper", "lower", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this application.

[0040] Embodiments of this application will now be described with reference to the accompanying drawings.

[0041] Figures 2 to 5 This illustration shows a specific embodiment of the unwinding feeding mechanism of this application, used to feed a plurality of sequentially connected electrical terminals to downstream processing equipment. Similar to conventional unwinding feeding mechanisms for electrical terminals, this embodiment also includes a base frame 1, on which a tray 2 is rotatably mounted. A product strip a and a separator paper strip b are wound on the tray. The product strip a consists of a plurality of electrical terminals a1 arranged sequentially and interconnected along its length. Score lines are provided between adjacent electrical terminals a1 to allow the downstream processing equipment to separate these terminals a1. The separator paper strip b is arranged abutting against the side of the product strip a. When the product strip a and the separator paper strip b are wound together on the tray 2, the separator paper strip b separates adjacent loops of product strip a from each other to prevent them from contacting and scratching each other. A strip guiding assembly 6 cooperates with the product strip a released from the tray 2 to guide the product strip a downstream.

[0042] In practical applications, when the material tray 2 conveys the product strip a wound on it downstream, the separator paper strip b used to protect the product strip a will inevitably be released simultaneously. If the released separator paper strip b is not collected and allowed to scatter, there is a risk that the separator paper strip b may get caught in the equipment, damaging production or even causing workplace injuries. Based on this, the unwinding feeding mechanism of this embodiment is also equipped with a paper strip rewinding tray 3, which is connected to the separator paper strip b released from the material tray 2 to rewind the separator paper strip onto it.

[0043] During operation, the paper tape take-up reel 3 applies a certain winding force to the separating paper tape b. Occasionally, the separating paper tape b breaks under this winding force. If the breakage of the separating paper tape b is not addressed promptly, the aforementioned potential hazard remains. Therefore, this embodiment also includes a reflective photoelectric sensor 4. This reflective photoelectric sensor 4 is commercially available, model number CX-441-P. The reflective photoelectric sensor 4 includes a transmitter and a receiver that cooperate with each other. During normal operation, the light emitted by the transmitter strikes the separating paper tape b between the paper tape take-up reel 3 and the material tray 2, and is reflected by the separating paper tape b to the receiver. Once the separating paper tape b breaks, the reflected light path is lost, and the receiver cannot receive the light emitted by the transmitter. The reflective photoelectric sensor 4 thus senses the paper breakage signal, enabling the production equipment to respond accordingly, such as stopping or issuing an alarm. Specifically, in this embodiment, an audible and visual alarm (not shown) is configured and connected to the reflective photoelectric sensor 4 circuit. Once a paper breakage event is detected, the audible and visual alarm emits an audible and visual alarm signal to alert the operator of the paper breakage problem.

[0044] To facilitate installation and improve the compactness of the mechanism, the aforementioned paper tape reel 3 and reflective photoelectric sensor 4 are also mounted on the base frame 1, and the paper tape reel 3 can rotate relative to the base frame 1. Furthermore, the reflective photoelectric sensor 4 is arranged on the conveying path of the separating paper tape b between the paper tape reel 3 and the material tray 2 to shorten the optical path and thus reduce the possibility of the optical path being blocked by external objects.

[0045] During operation, the separator paper tape b is continuously released, the winding thickness of the material tray 2 decreases, while the winding thickness of the paper tape take-up tray 3 increases. Therefore, the angle between the separator paper tape b and the material tray 2 and take-up tray 3 continuously changes. When the angle change is large, the reflection angle of the transmitter light by the separator paper tape b changes significantly, potentially causing the receiver to fail to receive the reflected light. Based on this, this embodiment sets the position of the reflective photoelectric sensor 4 on the base 1 to be adjustable to accommodate changes in the angle of the separator paper tape b. In some embodiments, program instructions written into the controller of the power component (e.g., a motor) used to adjust the position of the reflective photoelectric sensor 4 allow the position to change according to the angle of the separator paper tape b between the material tray 2 and the take-up tray 3. In some embodiments, the operator can manually adjust the position of the reflective photoelectric sensor 4 to adapt to the current working conditions.

[0046] To facilitate the overall movement of the mechanism, this embodiment is equipped with casters 5 with omnidirectional wheel structure at the bottom of the base frame 1.

[0047] In addition, in order to release the product strip a on the tray 2 more smoothly and to prevent the released product strip a from arching or folding, this embodiment also includes a strip traction component (not shown in the figure) that connects the product strip a released from the tray 2 to pull the product strip downstream. Since the structure of the strip traction component with this function is well known to those skilled in the art, and its specific structure is not an improvement point of this application, it will not be described in detail.
