Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a tire forming material supply device for transporting and supplying tire forming materials such as treads.

(Prior art, problems) Conventionally, a tread used in tire molding is cut into the length of one tire and then transported to a molding factory by a transport truck a, as shown in Fig. 4. During tire molding, the worker transfers the tread in the transport vehicle a onto the feeder b and supplies it to the tire molding machine c, but it is necessary to secure a wide working area for the worker as shown in the figure. , transportation trolley a
The work of moving the tread from the tread to the feeder B requires considerable labor and has a negative effect on tire forming, so it is desired to save labor.

(Objective of the Invention, Means for Solving the Problems) The present invention was developed in order to deal with the above-mentioned problems in the conventional supply of tire molding materials. a tire molding material transportation truck having a conveyor; an elevator for the transportation truck; a feeder comprising a tray for receiving and supplying the material from each of the conveyors; and operating the elevator by operating the tray. The conveyor is characterized by a configuration including a delivery drive control mechanism that connects and drives each of the conveyors individually to the tray, and is arranged in multiple upper and lower stages in front of a feeder equipped with a tray that receives and supplies tire molding material. By arranging a transport vehicle for tire molding material having a plurality of conveyors, and by operating the tray, each of the conveyors is connected to the tray by an elevator and driven. It is an object of the present invention to provide a tire molding material supply device which enables automatic transfer of tire molding material between machines, significantly improves supply performance, saves labor, and solves the above-mentioned problems.

(Embodiment of the Invention) An embodiment of the present invention is shown in FIGS.
20 is an elevator for the transport vehicle 10;
Reference numeral 30 is a supply machine that receives and supplies the tread a delivered from the transport vehicle 10, and 1 is a tire molding machine that receives the tread a that is supplied from the supply machine 30.The transport vehicle 10 will be described in detail as follows. Horizontally arranged conveyors 12 fixed to the truck frame 10a are arranged in multiple stages (six in the figure) above and below, and each conveyor 12 has a group of 13 rotatably supported rollers at appropriate intervals. A chain 15 is wound around a sprocket 14 fixed to the roller 13, and the chain 15 rotates the roller 13 to move the tread a to the left in the figure.

In addition, to explain the elevator 20 in detail, it is attached to the lower part of the transport trolley 10, and is attached to the lower part of the transport trolley 10.
It is a mechanism that raises and lowers the 0 in the vertical direction while keeping it horizontal, and is made up of cylinders, jacks, etc. Moreover, it can also be configured to be disposed on the lower side of the transport trolley 10.

Furthermore, to explain the feeder 30 in detail,
A tray 33 is installed on the upper part of the machine frame 30a so that it can be raised and lowered by a bearing 31, and has a group of rollers 32 for receiving and supplying the tread a sent out from each conveyor 12 of the transport vehicle 10. A setting seat 35 for receiving and setting the transport cart 10 is provided on the lower front side of the transport cart 30a.

Furthermore, a motor 41 for driving the conveyor is provided on the side of the machine frame 30a of the feeder 30, and a gear 44 provided on the front side of the upper part of the machine frame 30a is connected to the motor 41 with a sprocket 43 and a chain 42. A sprocket 45 is fixed to the roller 13 on the tip side of each conveyor 12,
When the transport vehicle 10 hits the set seat 35 and is stopped, and the transport vehicle 10 is raised by the elevator 20, each sprocket 45 of each conveyor 12
are arranged to mesh with the gears 44 individually,
Chain 42 and sprocket 4 by motor 41
3, the group of rollers 13 can be rotationally driven through the gears 44 and 45, and also through the chain 15 and sprocket 14 of the conveyor 12, and the tread a
The mechanism is such that the conveyor 12 sends the liquid to the tray 33 and then feeds it to the molding machine 1. Furthermore, it is provided in the machine frame 30a and is turned on when the tray 33 is moved to the solid line position in FIG. and a limit switch 4 provided on the machine frame 30a that is turned on when the tray 33 is placed in the standby position with the two-dot chain line in FIG.
7 and a proximity switch 48 provided on the front side of the upper part of the machine frame 30a and opposite to the tip of the conveyor 12, and when the tray 33 is tilted to the operating position, the limit switch 46 is turned on and the motor 41 is rotated. Chain 42, sprocket 43, gear 44,
45, a chain 15, and a sprocket 14, the group of rollers 13 of the conveyor 12 is rotationally driven, and the tread a is delivered to the tray 33 and further supplied to the molding machine 1. After the supply is finished, the roller 13 group of the conveyor 12 is
When set up and set to standby position, limit switch 47
is turned on, the elevator 20 is activated, and the transport trolley 10
When the gear 45 of the next conveyor 12 engages with the gear 44, the elevator 20 is stopped by the proximity switch 48, and the elevator 20 is placed in a position to send out the tray a from the next conveyor 12, and the tray 33 is brought down. When in the operating position, the feed drive control mechanism 40 automatically feeds and supplies the tread a from the next conveyor 12 as described above.

(Operations and Effects of the Invention) As described above, the present invention provides a tire molding material a having a plurality of conveyors 12 arranged in a plurality of upper and lower stages.
transport trolley 10 and an elevator 20 of the transport trolley 10
, a feeder 30 equipped with a tray 33 that receives and supplies the material a from each conveyor 12; and an elevator 20 is actuated by operating the tray 33, and each conveyor 12 is individually connected to the tray 33 and driven. Since the delivery drive control mechanism 40 is provided, the tire molding material a is loaded on each conveyor 12 of the transport vehicle 10 and transported, the transport vehicle 10 is placed in front of the feeder 30, and the tray 33 of the feeder is moved. When operated, the elevator 20 is actuated by the delivery drive control mechanism 40 to raise the transport vehicle 10 and move the conveyor 12 to the tray 33.
By repeating the operation of the tray 33, the tire molding material a on each conveyor 12 is automatically delivered to the tray 33 and supplied to the molding machine 1, which greatly saves labor and is excellent. It has excellent transportation and supply performance.

Furthermore, according to the device of the present invention, the transport cart 10 can be placed close to the feeder 30 as shown in FIG. 3, and since the worker's work is limited to manipulating the tray 33, the work space can be significantly reduced. It has the following effects.

Although the present invention has been described above with reference to embodiments, it goes without saying that the present invention is not limited to such embodiments, and that various design modifications can be made without departing from the spirit of the present invention. .
