Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tire production and processing, and particularly relates to a lifting suspension chain conveying and tire unloading device. Background Art
[0002] In the process of tire production, after the semi-finished tire embryo is produced by the tire forming machine, it is necessary to convey the tire embryo to the next process to coat the inner wall of the tire embryo with an isolating agent, and this process is called powder spraying, so that the green tire can be smoothly demolded after vulcanization. In the prior art, the following two conveying methods are often adopted to transport the formed tire embryo to the powder spraying machine: one is that workers use transportation tools such as mobile trolleys to transfer the formed tire embryo to the side of the powder spraying machine, and this conveying method has low efficiency and high labor intensity; the other is to vertically hang the tire embryo on the suspension sling, convey it to the tire unloading conveyor belt, and unload the tire embryo by using the speed difference between the conveying chain and the tire unloading conveyor belt, and then enter the powder spraying machine. However, in the current process of conveying the formed tire embryo by the suspension chain to unload the tire, a fixed-height and fixed-speed tire unloading method is often adopted. This tire unloading form cannot be compatible with the conveying of tires with a large cross-size at the same time, and there are phenomena that small-size tires cannot be unloaded and large-size tires crush the hooks. A production line with a fixed height is difficult to meet the conveying and tire unloading requirements of tires with a large cross-size, which brings inconvenience to production, production scheduling and maintenance.

[0030] See Figures 1-4 :
[0031] A lifting suspension chain conveying tire unloading device, comprising a mounting bracket 1, a conveyor belt device 2 arranged on the mounting bracket 1, and a free roller frame 22 installed at the tail of the conveyor belt device 2.
[0032] The mounting bracket 1 includes a front mounting portion 10 and a rear mounting portion 11. The horizontal height of the front mounting portion 10 is lower than that of the rear mounting portion 11. A lifting device 3 is arranged on the front mounting portion 10. The output end of the lifting device 3 is rotatably connected to a front support frame 12. The rear mounting portion 11 is rotatably connected to a rear support frame 13. The upper ends of the front support frame 12 and the rear support frame 13 are both connected to the lower end of the conveyor belt device 2. Specifically, the upper end of the front support frame 12 is connected to the left side of the lower end of the conveyor belt device 2, and the number of the rear support frames 13 is two, and the two rear support frames 13 are both arranged on the right side of the lower end of the conveyor belt device 2.
[0033] It can be understood that the lifting device 3 drives the conveyor belt device 2 to rotate and lift or lower through the front support frame 12. The conveyor belt device 2 is driven by a reduction motor 20 to operate, and a motor shield 21 is arranged outside the reduction motor 20. Four support legs 17 are provided at the lower end of the mounting bracket 1 to play a supporting role.
[0034] The conveyor belt device 2 is arranged below the conveying route of the suspension chain 5. A plurality of hooks 50 are arranged on the suspension chain 5, and a formed tire blank 6 is suspended by the hooks 50, and the formed tire blank 6 is conveyed to the conveyor belt device 2 for tire unloading.
[0035] As an implementation manner, the difference in horizontal height between the rear mounting portion 11 and the front mounting portion 10 is set as the length of the lifting device 3.
[0036] As an implementation manner, the free roller frame 22 is arc-shaped and arranged obliquely downward. It can be understood that when the suspension chain 5 conveys the formed tire blank 6 to the conveyor belt device 2, the lower end of the formed tire blank 6 first contacts the free roller frame 22, and then the formed tire blank 6 enters the conveyor belt device 2 for tire unloading. Preferably, the head end of the free roller frame 22 is at the same horizontal height as the tail of the conveyor belt device 2, and the tail end of the free roller frame 22 faces downward.
[0037] As an implementation manner, a detection device for detecting the size of a tire is installed on the free roller rack 22. The detection device and the lifting device 3 are respectively electrically connected to a controller. The controller controls the lifting device 3 to adjust the lifting height of the conveyor belt device 2 and the conveyor belt speed of the conveyor belt device 2 according to the size of the large or small tire detected by the detection device, so as to achieve the compatibility of conveying tires with a relatively large size difference, effectively reduce abnormal tire unloading phenomena, reduce failures, increase the flexibility of production scheduling and reduce the failure rate of the equipment. It can be understood that the tire refers to the formed tire embryo 6 conveyed by the above-mentioned suspension chain 5.
[0038] Preferably, when the detection device detects that the large tire is conveyed by the suspension chain 5, the lifting height of the conveyor belt device 2 drops to a preset position. When the detection device detects a small tire, the lifting height of the conveyor belt device 2 rises to a preset position.
[0039] As an implementation manner, the detection device is a non-contact sensor for detecting the size of an object.
[0040] As an implementation manner, a buffer 4 is provided between the mounting bracket 1 and the conveyor belt device 2. The buffer 4 can effectively buffer the impact brought by the lifting process of the conveyor belt device 2, protect the stability of the equipment, and thus extend the service life of the equipment.
[0041] As an implementation manner, the number of the buffers 4 is two. The two buffers 4 are respectively arranged on both sides of the lifting device 3 to play a better buffering role. Specifically, the number of the front support frame 12 and the lifting device 3 is one, and the front support frame 12 is connected to the middle of the lower left side of the conveyor belt device 2.
[0042] As an implementation manner, the lifting device 3 adopts a cylinder. The cylinder has strong load-bearing capacity and adaptability, and is easy to install and maintain.
[0043] As an implementation manner, side retaining rollers 14 are arranged on both sides of the conveyor belt device 2 to effectively prevent the formed tire embryo 6 from falling off the conveyor belt device 2. Specifically, the side retaining rollers 14 include mounting guardrails 140 on both sides. A C-shaped profile 141 is installed on the upper side of the mounting guardrail 140. The opening of the C-shaped profile 141 faces the other mounting guardrail 140. Mounting columns 142 are installed on both side walls of the C-shaped profile 141, and rotating rollers 143 are rotatably connected to the mounting columns 142.
[0044] As an implementation manner, a pedestal bearing 15 is installed below the rear support frame 13, and a rotating shaft fixing seat is arranged at the rear mounting portion 11. The pedestal bearing 15 is connected to the rotating shaft fixing seat through a rotating shaft 16. Specifically, the rotating shaft 16 passes through the pedestal bearing 15 and the rotating shaft fixing seat. When the lifting device 3 adjusts the lifting height of the conveyor belt device 2, the conveyor belt device 2 rotates around the rotating shaft 16 to rise or fall.
[0045] The description of the above-mentioned specification and embodiments is used to explain the protection scope of the present utility model, but does not constitute a limitation to the protection scope of the present utility model. Modifications, equivalent replacements or other improvements to the embodiments of the present utility model or some of its technical features obtained by those of ordinary skill in the art through logical analysis, reasoning or limited experiments in combination with common general knowledge, general technical knowledge in this field and / or the prior art shall be included within the protection scope of the present utility model.
