Description

[Detailed Description of the Invention] [Industrial Application Field] This invention safely and efficiently transports rubber bodies, especially deformed and heavy rubber bodies such as natural rubber, from a feeding device to the next process such as a cutting device. The present invention relates to a method for supplying a rubber body and an apparatus therefor.

[Conventional technology]

Conventionally, methods for supplying a deformed and heavy rubber body such as natural rubber from the feeding device side to the next process such as a cutting device include, for example, a piercing method in which the rubber body is pierced with a fork or the like, or a method in which the rubber body is clamped. A chucking method for supplying the liquid is currently in use.

[Problem that the invention seeks to solve]

However, in all of the above methods, complete automation is difficult because the rubber body itself, such as natural rubber, is deformed and the weight is large (typically 110 kg/bale for natural rubber), and it is difficult to fully automate the process. It is extremely dangerous if the product falls on the way, so a highly safe and efficient method is to have workers line up on the conveyor, use hand keys, and operate a foot switch to supply the product. A method was being used to do so.

For this reason, it has traditionally been impossible to implement unmanned systems or automation, and when integrated online, there has been a problem in that productivity decreases in terms of work efficiency, and it causes an increase in personnel, making it extremely difficult to go online. . In order to achieve complete automation, it is possible to install an automatic machine using the method described above, but such an automatic machine would be an expensive system and would require a large space. It was hot.

[Purpose of the invention]

This invention was devised by focusing on the conventional problems, and its purpose is to be able to supply rubber bodies automatically without manual operation, and to do so in a safe and reliable manner. The object of the present invention is to provide a method and apparatus for supplying rubber bodies, which can be supplied to the rubber body and which can significantly improve productivity and workability.

[Means to solve the problem]

In order to achieve the above object, the gist of the present invention is to supply a rubber body in the following steps.

(a) A step in which the rubber bodies that are continuously conveyed via the alignment conveyor connected to the previous process are transferred onto a transfer conveyor equipped with a forward/backward drive device.

(b) Detecting that the rubber body has been transferred onto the transfer conveyor, actuating the advance/retreat drive device, and rotating the transfer conveyor on which the rubber body is placed through the advance/retreat drive device. The process of advancing toward the cutting device.

(c) With the transfer conveyor advanced to a predetermined position, the rubber body placed on the rotationally driven transfer conveyor is transferred onto the free roller of the cutting device, and after the rubber body is transferred. is a process in which the rubber body on the free roller is pressed until it touches the guide plate at the leading end of the transfer conveyor.

(d) When it detects that the rubber body has been transferred onto the free roller, the cutting device is activated, moves the rubber body to the cutter mechanism side, cuts it into a predetermined size and shape, and then connects it to the next process. The process of transferring the material to the input conveyor.

Further, the present invention provides a movable carriage equipped with a forward/backward drive device installed between an alignment conveyor connected to the previous process and a cutting device continuous to an input conveyor connected to the next process, and The main feature is that a transfer conveyor is installed to transfer the rubber bodies transferred by the alignment conveyor and sequentially transfer the rubber bodies to the free rollers of the cutting device.

[Embodiments of the invention]

Embodiments of the present invention will be described below based on the accompanying drawings.

FIG. 1 and FIG. 2 show a schematic plan view and a front view of the entire supply device 1 according to the present invention. It is arranged between a cutting device 4 that is continuous with an input conveyor 3 that is connected to the next process.

The alignment conveyor 2 is rotationally driven by a drive motor 5, and a detection means 6 such as a limit switch or a phototube for detecting the conveyance position of the rubber body W is provided at its discharge end 2a.

The feeding device 1 disposed on the discharge end 2a side of the alignment conveyor 2 is connected to a movable cart 9 via guide rollers 8 on a guide rail 7 disposed inclined upward toward the cutting device 4 side. A transfer conveyor 10 is mounted on the moving trolley 9 so as to be movable.
is placed.

A moving cart 9 placed on the guide rail 7
is the drive cylinder 1 in the forward/backward drive device.
The ends of the two rods 11a are connected to each other, and the cylinder body 11b is fixed on the base 12.

Further, the transfer conveyor 10 is configured to be rotationally driven via a drive motor 13 installed on the moving cart 9.

The drive cylinder 11 is set to be electrically linked and driven with the detection means 6 provided at the discharge end 2a of the alignment conveyor 2.

Next, the cutting device 4 installed on the discharge end 10a side of the transfer conveyor 10 is placed on a pedestal 15 installed in a direction perpendicular to the transfer conveyor 10, as shown in FIGS. 1, 3, and 4. , a plurality of free rollers 16, a cutter mechanism 17 and a push-out mechanism 18 arranged on both sides of the free roller 16, and a rubber body W planted on the pedestal 15.
It is composed of a guide plate 19.

The cutter mechanism 17 has a plurality of cutter blades 21 arranged at predetermined intervals on a frame 20 fixed on a pedestal 15, and a space is formed between the cutter blades 21 to hold the cut rubber body W. It is arranged so that it is extruded and falls onto the input conveyor 3 which is connected to the next process.

The push-out mechanism 18 also includes a press plate 24 movably mounted on a guide rail 22 on the pedestal 15 via wheels 23, and a press cylinder 25 that moves the press plate 24 toward the cutter mechanism 17.
As shown in FIG. 4, the front surface of the pressing plate 24 is provided with a plurality of protrusions 26 that fit into the spaces between the cutter blades 21 disposed on the frame 20.

Note that 14 is a free roller 16 and a guide plate 19.
A detecting means such as a limit switch or a phototube provided close to the free roller 16 detects that the rubber body W has been pushed out and transferred until it comes into contact with the guide plate 19 provided on one side edge of the free roller 16. It is something to do.

Next, a method for supplying the rubber body W of the present invention having the above-described configuration will be explained.

First, the rubber bodies W supplied from the previous process are transferred by the alignment conveyor 2, and when they reach the discharge end 2a, their position is detected by a detection means 6 such as a limit switch or a phototube, and at the same time, the transfer conveyor 10 is driven. When the motor 13 starts driving, the rubber bodies W on the alignment conveyor 2 are transferred onto the transfer conveyor 10.

Next, when the rubber body W is transferred onto the transfer conveyor 10, the drive cylinder 11 starts to contract, and the transfer conveyor 10 is driven to rotate together with the moving cart 9.
The rubber body W placed thereon is moved along the guide rail 7 toward the cutting device 4 side.

Then, when a set time (set by a timer) corresponding to the moving distance of the drive cylinder 11 to the frontmost position of the movable cart 9 has elapsed, the drive cylinder 1
1 is temporarily stopped, and the rubber body W is transferred to a temporary position on the free roller 16 of the cutting device 4 via the transfer conveyor 10 which is rotationally driven by the drive motor 13.

In this way, the free roller 16 of the rubber body W
Once the upward transfer operation is completed, the drive cylinder 11 that drives the moving carriage 9 starts an extension operation, and returns the transfer conveyor 10 together with the moving carriage 9 to its original position. Then, the contraction operation of the drive cylinder 11 is started again, and the movable cart 9 on which the transfer conveyor 10 which is rotationally driven by the drive motor 13 is mounted is moved to the rubber body W mounted on the free roller 16, and then At the leading end side of the transfer conveyor 10, the rear surface of the rubber body W is pressed until it comes into contact with a guide plate 19 erected at one side edge of the free roller 16.

When the positioning of the rubber body W is completed in this manner and a certain period of time has elapsed, the drive cylinder 11 that drives the movable trolley 9 starts an extension operation, and the transfer conveyor 10 is returned to the original position together with the movable trolley 9. .

Next, when the rubber body W is placed at a fixed position on the free roller 16, this is detected via the detection means 14, and the press cylinder 25 starts to extend, and the press plate 24 moves along the guide rail 22. While moving toward the cutter mechanism 17 side, the rubber body W is pressed against the cutter blade 21 by the protrusion 26 provided on the front surface thereof. Then, when the protrusion 26 of the pressing plate 24 fits into the space between the cutter blades 21 due to the pressing force of the pressing cylinder 25, the rubber body W is cut into a plurality of flat plates, and the cut rubber body W is transferred to the input conveyor 3. They fall one after another and are transported to the next process.

By repeating such operations, the rubber body W can be efficiently supplied to the next process.

In the above embodiment, the drive motor 13 constantly drives the transfer conveyor 10 to rotate the rubber body W.
is transferred onto the free roller 16, and even after the rubber body W is transferred onto the free roller 16, the transfer conveyor 1 that is still driving the rubber body W to rotate continues.
0 until it comes into contact with the guide plate 19. However, the present invention is not limited to this embodiment, and only when transferring the rubber body W onto the free roller 16, the transfer conveyor 10 is rotationally driven via the drive motor 13, and the rubber body W is brought into contact with the guide plate 19. At times, the drive motor 13 may be stopped and the transfer conveyor 10 may be non-rotating.

〔Effect of the invention〕

As described above, this invention installs a movable transfer cart equipped with a forward/backward drive device between the alignment conveyor connected to the previous process and the cutting device continuous to the input conveyor connected to the next process. A transfer conveyor is installed to transfer the rubber bodies transferred by the alignment conveyor onto the transfer trolley and sequentially transfer the rubber bodies to the free roller of the cutting device, thereby transferring the rubber bodies from the previous process to the next process. Because it is continuously supplied, deformed and heavy rubber bodies can be safely and smoothly transferred from the previous process to the next process without requiring much manpower, and the mixing line can be moved online. This method is easy to use, and furthermore, the entire system can be made unmanned, which has the effect of significantly improving the workability of supplying rubber bodies and productivity.
