Description

Technical Field

[0001] The utility model relates to the technical field of tire vulcanization production, in particular to a device for preventing a vulcanization bladder from being clamped and tire vulcanization equipment. Background Art

[0002] In a tire vulcanizer of the bladder type, a bladder is inserted into the interior of a raw tire, and after the bladder and the raw tire are housed in the mold by closing the mold, a heating and pressurizing medium such as high-temperature and high-pressure steam and nitrogen is supplied into the bladder to expand the bladder, thereby maintaining the interior of the raw tire (the bladder) at the desired temperature and pressure, and at the same time, the raw tire is pushed against the inner surface of the mold by the expansion force of the bladder.

[0003] In the above process, when the vulcanization workers spray the release agent, they usually close the vacuum hand valve to make the capsule slightly shaped to facilitate the application of the release agent. If the workers forget to open it when loading the pot, vacuuming will not be possible after shaping, resulting in the capsule being unable to enter the tire blank, causing the capsule to be clamped in the tire and poor capsule folding. Utility Model Content

[0004] In view of the shortcomings of the prior art, a device for preventing vulcanization bladder from being clamped and a tire vulcanization equipment are proposed, which solves the problem in the above-mentioned background technology that the staff forgets to open the vacuum hand valve when loading the pot, and vacuum cannot be performed after shaping, resulting in the bladder being unable to enter the interior of the tire embryo.

[0005] In order to achieve the above purpose, the utility model proposes the following technologies to achieve it:

[0006] A device for preventing vulcanization capsules from being clamped comprises an air duct assembly, on which a sensor assembly is arranged, the sensor assembly signal is connected to a control unit, the control unit is control-connected to a pot-loading robot, the sensor assembly detects the air duct assembly and transmits a signal to the control unit, and the control unit controls the action of the pot-loading robot according to the detection signal.

[0007] Furthermore, the air duct assembly includes a vacuum air duct, on which a first sensor and a vacuum on-off manual valve are provided, and the first sensor is provided between the vacuum manual valve and an inlet air source.

[0008] Furthermore, the air duct assembly includes a shaped air duct, on which a second sensor and a shaped on-off manual valve are arranged, and the second sensor is arranged between the shaped on-off manual valve and the inlet air source.

[0009] Furthermore, the air duct assembly includes an upper ring lifting air duct, on which a third sensor and an upper ring lifting on-off manual valve are arranged, and the third sensor is arranged between the upper ring lifting on-off manual valve and the inlet air source.

[0010] Furthermore, the control unit is signal-connected to an alarm unit, and the control unit controls whether the alarm unit sends out an alarm signal according to the detection signal of the sensor assembly.

[0011] Furthermore, the sensor assembly is a digital pressure sensor, and the digital pressure sensor is sealed and connected to the vacuum air path, the shaping air path and the upper ring lifting air path respectively.

[0012] Furthermore, the digital pressure sensor is fixedly installed via a pressure-guiding tube, and the pressure-guiding tube is respectively arranged perpendicular to the vacuuming air path, the shaping air path and the upper ring lifting air path.

[0013] A tire vulcanization equipment comprises any one of the above-mentioned devices for preventing vulcanization bladder from being clamped. Furthermore,

[0014] Compared with the prior art, the comprehensive effects brought by the utility model include:

[0015] By arranging a sensor assembly on the air duct assembly, the sensor detects the air pressure in each air duct and transmits the detection result to the control unit.

[0019] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the utility model.

[0020] In this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. The orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "top", etc. is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation to the utility model.

[0021] like Figure 1 to Figure 2 As shown, a device for preventing vulcanization capsules from being trapped comprises an air duct assembly, on which a sensor assembly is arranged, and the sensor assembly signal is connected to a control unit 1, and the control unit 1 is control-connected to a pot-loading robot. The sensor assembly detects the air duct assembly and transmits a signal to the control unit 1, and the control unit 1 controls the action of the pot-loading robot according to the detection signal.

[0022] By setting a sensor assembly on the air duct assembly, the sensor detects the air pressure in each air duct and transmits the detection result to the control unit 1. When the staff makes an operating error and the air pressure value in the air duct detected by the sensor is different from the air pressure under normal circumstances, the control unit determines that the current production conditions do not meet the conditions, thereby controlling the pot loading robot to stop moving and shut down. The above-mentioned setting adds a layer of error-proof protection to the tire process. The vulcanization device automatically shuts down when an abnormality occurs through detection to prevent the failure to vacuumize after shaping due to the staff's error, and the capsule cannot completely enter the tire embryo, resulting in tire bladder clamping and poor capsule folding.

[0023] The present application realizes the function of preventing error shutdown by adding a physical detection structure, so as to prevent the capsule from being unable to completely enter the tire embryo due to the inability to vacuumize after shaping, resulting in tire bladder clamping and poor bladder folding.

[0024] Specifically, the control unit 1 in the present application monitors and determines the detection value of the sensor component through the PLC module. This part of the algorithm and logic is the existing technology and will not be repeated here.

[0025] Specifically, the sensor component is a digital pressure sensor. When the mold is closed, the digital pressure sensor detects whether there is wind pressure in each air path. When the pressure value is lower than 0.35Mpa, it is considered that there is no wind pressure. The digital pressure sensor transmits a no wind pressure signal to the PLC module in the control unit 1. The PLC module receives the no wind pressure signal and determines that the current production conditions are unqualified, and then the control unit 1 controls the pot loading robot not to move in, and the pot cannot be loaded on site.

[0026] Preferably, the digital pressure sensor in the present application is the JK45P-12B-F1 digital pressure sensor.

[0027] Preferably, the control unit is signal-connected to an alarm unit 12, and the control unit 1 controls whether the alarm unit 12 sends out an alarm signal according to the detection signal of the sensor assembly.

[0028] Through the above-mentioned arrangement, when the air pressure in the air path is abnormal, the control unit 1 controls the pot loading robot to stop transporting and sounds an alarm to remind the staff that the current production conditions do not meet the requirements, thereby facilitating the staff to discover errors more promptly for correction, thereby improving production efficiency; when the staff completes the adjustment and the equipment is turned on, the alarm unit 12 stops the alarm at the same time.

[0029] In the device for preventing vulcanization capsule from being trapped in the present embodiment, the air path assembly includes a vacuum air path 2, on which a first sensor 3 and a vacuum on-off manual valve 4 are provided, and the first sensor 3 is arranged between the vacuum manual valve 4 and the inlet air source 5.

[0030] Specifically, the first sensor 3 is a digital pressure sensor. When the mold is closed, the vacuum air path 2 is normally in the open state to shrink the airbag for easy installation of the tire embryo. At this time, the first sensor 3 detects that there should be wind pressure in the vacuum air path 2. When the vulcanization employee sprays the isolation agent, the vacuum on-off manual valve 4 is closed so that the capsule is micro-shaped and not opened when the pot is loaded. After shaping, vacuuming cannot be performed. At this time, there is no wind pressure in the vacuum air path 2. The first sensor 3 transmits a signal to the control unit 1 to further stop the pot loading robot until the vacuum on-off manual valve 4 is opened.

[0031] In the device for preventing vulcanization capsule from being trapped in this embodiment, the air path assembly includes a fixed air path 6, on which a second sensor 7 and a fixed on-off manual valve 8 are provided, and the second sensor 7 is arranged between the fixed on-off manual valve 8 and the inlet air source 5.

[0032] Specifically, in the shaping process, the shaping air passage 6 is in an open state, and there should be wind pressure in the air passage. When the staff forgets to open the shaping on-off manual valve 8, the second sensor 7 detects that there is no wind pressure in the shaping air passage 6 and transmits a signal to the control unit 1 to stop the pot loading robot until the shaping on-off manual valve 8 is opened.

[0033] In the device for preventing vulcanization capsule from being trapped in the present embodiment, the air path assembly includes an upper ring lifting air path 9, on which a third sensor 10 and an upper ring lifting on-off manual valve 11 are arranged, and the third sensor 10 is arranged between the upper ring lifting on-off manual valve 11 and the inlet air source 5.

[0034] Specifically, in the upper ring lifting and stopping process, the upper ring lifting air passage 9 is in an open state, and there should be wind pressure in the air passage. When the staff forgets to open the upper ring lifting on-off manual valve 11, the third sensor 10 detects that there is no wind pressure in the upper ring lifting air passage 9 and transmits a signal to the control unit 1 to stop the pot loading robot until the upper ring lifting on-off manual valve 11 is opened and the equipment is started for normal vulcanization.

[0035] In the device for preventing vulcanization capsule from being trapped in the present embodiment, the digital pressure sensor is sealedly connected to the vacuum air path 2, the shaping air path 6 and the upper ring lifting air path 9 respectively, and the digital pressure sensor is fixedly installed through a pressure-leading pipe, and the pressure-leading pipe is arranged perpendicular to the vacuum air path 2, the shaping air path 6 and the upper ring lifting air path 9 respectively.

[0036] The above setting makes the reading of the digital pressure sensor more accurate, so that the air pressure monitoring in each air path is more timely and accurate, and can better control the shutdown and startup of the equipment in conjunction with the control unit 1 to ensure the quality of vulcanization production and avoid capsule discounts.

[0037] On the other hand, the present application also proposes a tire vulcanization equipment, comprising any one of the above-mentioned devices for preventing vulcanization bladder from being clamped.

[0038] All the beneficial effects of the tire vulcanization equipment including the device for preventing the vulcanization bladder from being clamped are not described in detail here.
