Technical Field

[0001] The utility model relates to the technical field of safety protection, in particular to a protection device. Background Art

[0002] The working principle of the box turning mechanism is to push the trolley into the box turning machine, control the opening and closing of the turning door by a cylinder, and drive the trolley to turn 180° by a motor for turning and feeding. During the working process of the box turning mechanism, there may be potential mechanical injury hazards such as pinching hands when in the lifting process, and there may be potential mechanical injury hazards such as smashing when in the process of raw material turning down. The existing protection device for the box turning mechanism uses a full-coverage metal guardrail. Although it can eliminate the safety hazards brought by the box turning mechanism, the safety hazards existing in the full-coverage metal guardrail still cannot be completely eliminated in the upper turning area and the lifting area; and another protection structure with the help of sensors not only has a high cost, but also cannot avoid the slag splashing in the working area outside the working area.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] Combined with Figures 1 to 4 As shown, the protection device provided in this embodiment is used to protect the box turning mechanism 10, thereby eliminating potential safety hazards and reducing costs. Specifically, the protection device includes a frame 100, a protection net assembly 200, a grating protection mechanism 300 and an optoelectronic protection mechanism 400: The protection net assembly 200 is installed on the frame 100 and encloses a working area with the frame 100, and the working area can accommodate the upward turning assembly of the box turning mechanism 10; The grating protection mechanism 300 is correspondingly connected to the frame 100 for the upward turning assembly; The optoelectronic protection mechanism 400 is arranged on the ground corresponding to the lifting assembly of the box turning mechanism 10.

[0035] Since the protection net assembly 200, the grating protection mechanism 300 and the optoelectronic protection mechanism 400 are provided simultaneously, during the operation of the box turning mechanism 10, the protection net assembly 200 is used to protect and isolate the working area to avoid the situation where the slag in the working area splashes outside the working area; The grating protection mechanism 300 can protect and warn the operator to avoid the operator entering the working area during the operation of the box turning mechanism 10, thereby eliminating the potential safety hazards brought by the box turning mechanism 10 and the protection net assembly 200 to the operator; The optoelectronic protection mechanism 400 protects and warns the lifting area, and can avoid situations such as material dropping during the operation of the lifting assembly, thereby eliminating the risk of the operator being injured by the material in the lifting area. In addition, since the sensor protection structure adopts the mutual cooperation of the grating protection mechanism 300 and the optoelectronic protection mechanism 400, and at the same time the cost of the grating protection mechanism 300 is relatively low, the protection cost is reduced while eliminating the potential safety hazards during the operation of the box turning mechanism 10.

[0036] Preferably, the grating protection mechanism 300 includes a mounting member 310, a first prompting member, and a grating assembly 320. The first prompting member and the grating assembly 320 are both disposed on the mounting member 310, and the first prompting member and the grating assembly 320 are communicatively connected.

[0037] Specifically, the grating assembly 320 includes a light emitter and a light receiver. The light emitter and the light receiver are oppositely disposed on the mounting member 310 and are respectively located on both sides of the flipping assembly. The grating assembly 320 is digitally programmed and controlled by a single-chip microcomputer and a microprocessor, so that the light emitter and the light receiver form an infrared light curtain warning barrier in a high-speed scanning state. When an operator enters the light curtain barrier area, that is, when the operator enters the working area, the control program converts and outputs a level signal to cause the first prompting member to issue an alarm; when the operator leaves the light curtain warning area, the first prompting member stops the alarm, thereby achieving the purpose of protecting and warning the operator.

[0038] Preferably, the optoelectronic protection mechanism 400 includes a mounting assembly 410 and an optoelectronic sensor 420. The mounting assembly 410 is fixedly disposed on the ground, and the optoelectronic sensor 420 is movably disposed on the mounting assembly 410. By changing the relative position of the optoelectronic sensor 420 on the movable assembly, the sensing area of the optoelectronic sensor 420 can be changed, so that an optoelectronic sensing area can be formed at different positions of the lifting assembly according to the actual situation of the turning box mechanism 10, thereby improving the overall protection. In addition, in order to further improve the protection effect of the lifting area, a plurality of optoelectronic sensors 420 can be provided according to the actual situation.

[0039] Further, in this embodiment, the optoelectronic sensor 420 is set as a diffuse reflection sensor. The diffuse reflection sensor includes an optoelectronic emitter and an optoelectronic receiver. The light emitted by the optoelectronic emitter is reflected by an object to the optoelectronic receiver, and in this process, the diffuse reflection sensor generates a switching signal. Since the switching signal can be generated by light reflection, the intensity of the light has little influence on the use effect of the diffuse reflection sensor. Therefore, the diffuse reflection sensor can be used to detect objects such as plastics, metals, papers, glasses, magnets, woods, and waters, thereby ensuring the protection effect of the optoelectronic protection mechanism 400 while further expanding the applicable range of the optoelectronic protection mechanism 400.

[0040] Furthermore, the photoelectric protection mechanism 400 further includes a second prompting member 430, which is disposed on the mounting assembly 410 and is in communication connection with the photoelectric sensor 420. When an operator enters the sensing area of ​​the diffuse reflection sensor, the light reflection state between the photoelectric transmitter and the photoelectric receiver is affected, thereby sending out an abnormal signal, and when the second prompting member 430 receives the abnormal signal from the diffuse reflection sensor, the second prompting member 430 sends out an alarm; when the operator leaves the sensing area of ​​the diffuse reflection sensor, the light reflection between the photoelectric transmitter and the photoelectric receiver returns to normal, and the second prompting member 430 stops the alarm.

[0041] Furthermore, the first prompting member and the second prompting member 430 are both configured as light prompters and / or sound prompters.

[0042] When the first prompting member and the second prompting member 430 are configured as light prompters, different colors of lights are emitted to indicate different states in the corresponding sensing area. For example, when an operator mistakenly enters the sensing area, the corresponding prompting member emits a red light, and when the operator leaves the sensing area, the corresponding prompting member emits a green light. When the first prompting member and the second prompting member 430 are configured as sound effect prompters, different sound effects are emitted to indicate different states in the corresponding sensing area.

[0043] Preferably, the mounting assembly 410 includes a base 411, a mounting plate 412 and a placement piece 413. The base 411 is disposed on the ground. The first end of the mounting plate 412 is fixedly connected to the base 411, and the second end extends along the Z direction. The placement piece 413 is movably disposed on the mounting plate 412 along the Z direction, and the photoelectric sensor 420 is disposed on the placement piece 413. By changing the relative position of the placement piece 413 and the mounting plate 412 in the Z direction, the photoelectric sensing area of ​​the photoelectric sensor 420 is changed, thereby improving the comprehensiveness of protection.

[0044] Specifically, the mounting plate 412 is provided with an adjustment groove 4121 extending in the Z direction, and the placement piece 413 is slidably connected to the adjustment groove 4121 through a sliding piece 414. The sliding piece 414 is configured as a threaded rod, and is correspondingly provided with an adjustment nut 4141; the first end of the threaded rod is fixedly connected to the placement piece 413, and the second end passes through the adjustment groove 4121 and is exposed on the side of the mounting plate 412 away from the placement piece 413, and the adjustment nut 4141 is threadedly connected to the second end of the threaded rod. When it is necessary to change the relative position of the placement piece 413 and the mounting plate 412 in the Z direction, first loosen the adjustment nut 4141, then adjust the threaded rod along the adjustment groove 4121 to the target position, and then tighten the adjustment nut 4141 to fix the placement piece 413 at the target position, thereby meeting the position requirement of the photoelectric sensor.

[0045] In some other embodiments, a plurality of adjustment through-holes are provided on the mounting plate 412. The plurality of adjustment through-holes are evenly spaced along the Z direction. According to actual requirements, the second end of the threaded rod is inserted into the adjustment through-holes at different positions, and the adjustment nut 4141 is threadedly connected to the second end of the threaded rod.

[0046] Preferably, the mounting assembly 410 further includes a shock-absorbing member 415. The object placement member 413 is provided in a cylindrical shape, the photoelectric sensor 420 is disposed inside the object placement member 413, and the shock-absorbing member 415 is disposed between the inner wall of the object placement member 413 and the photoelectric sensor 420.

[0047] Specifically, in this embodiment, the shock-absorbing member 415 is provided in a cylindrical shape, sleeved on the photoelectric sensor 420, and abuts against the inner wall of the object placement member 413. Moreover, the shock-absorbing member 415 is made of rubber, silica gel, sponge or foam to ensure its shock-absorbing effect. Since the shock-absorbing member 415 is provided between the object placement member 413 and the photoelectric sensor 420, when an external component or material hits the mounting assembly 410, the shock-absorbing member 415 can weaken the external force transmitted to the photoelectric sensor 420 through the object placement member 413, thereby achieving the purpose of shock-absorbing for the photoelectric sensor 420 and ensuring the use stability and use effect of the photoelectric sensor 420.

[0048] In some other embodiments, the shock-absorbing member 415 can be provided as a spring. The two ends of the spring are respectively connected to the inner wall of the object placement member 413 and the photoelectric sensor 420; and a plurality of springs are provided. The plurality of springs are spaced along the circumferential direction of the object placement member 413. When an external component or material hits the mounting assembly 410, the plurality of springs are stressed and telescoped to achieve the purpose of shock-absorbing for the photoelectric sensor 420.

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
