[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bale cutting device.
[0002]
[Prior art]
In general, a bale is a lump of synthetic rubber and is used as a raw material when manufacturing a tire.
Such a bale is arbitrarily divided and cut into various types of divided bales having different weights, and a divided bale having a weight suitable for the purpose is selected and used.
[0003]
Regarding the selection and cutting of the bale, the following problems have been pointed out.
That is, when selecting the bale, the one that suits the purpose is selected from a plurality of types of divided bale arbitrarily divided and cut. This makes it difficult to store and manage the bale. On the other hand, when cutting the bale, the operator cuts at an approximate position according to the amount of the eye. Therefore, the weight accuracy is remarkably deteriorated.
[0004]
Therefore, the applicant of the present application has proposed a bale cutting device capable of cutting a bale into a predetermined weight in Japanese Patent Application Laid-Open No. 11-221796.
The bale cutting device disclosed in this publication discloses feeding a bail while bringing a measuring element into contact with the outer surface of the bale, and a cross-sectional area when cut along a plane perpendicular to the feeding direction is set to a predetermined pitch in the feeding direction. A cross-sectional area distribution is obtained every time, and based on this cross-sectional area distribution, a dividing surface that divides a plurality of predetermined volume areas in the feed direction is obtained, and the bale is cut at this dividing surface. (Hereinafter referred to as “prior art”).
[0005]
[Problems to be solved by the invention]
However, in the bale cutting device according to the above-described prior art, the bail is fed from the feed mechanism toward the payout mechanism, the cutter is lowered, and the bale is sequentially cut at the dividing surface. For this reason, a stopper mechanism for stopping the bale separation surface just below the cutter is required. As a result, the actual situation is that the configuration of the apparatus is complicated.
[0006]
This invention is made | formed in view of the said technical subject, and makes it the subject to provide the bale cutting device which can simplify the structure of an apparatus.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, the present invention is for dividing and cutting a substantially rectangular parallelepiped bale into a plurality of pieces,
A cutting table for placing the veil;
This is provided retractably the cutting table from both sides against the bale, and a pair of guides that sandwich the both sides of the length direction of the substantially rectangular parallelepiped bale,

[0008]
In the above configuration, when the bail is placed on the cutting table, the length measuring means advances the guide to sandwich the bale on the cutting table along the length direction, and measures the bale length. Prior to cutting the bale along the width direction, the control means controls the advance / retreat operation of the guide based on the bale length measured by the length measuring means, and holds the bale between the guides on the cutting table. The cutting position along the width direction of the bale is moved directly below the cutter. Thereafter, the control means lowers the cutter while sandwiching the bail with the guide, and cuts the bale along the width direction.

Using the determined division mode as a parameter, the calculation means obtains a cutting position along the width direction of the bale based on the bale length measured by the length measurement means. Based on the obtained cutting position along the bale width direction, the control means controls the advance / retreat operation of the guide and aligns the cutting position with the cutter. When the determined division mode is a mode in which the bale is cut along the length direction, the control unit drives the rotation unit to rotate the cutting table. When a measurement value is input from the width measuring unit, the calculating unit obtains a cutting position along the length direction of the bale based on the bale width measured by the width measuring unit using the determined division mode as a parameter. Based on the obtained cutting position along the length direction of the bale, the control means controls the advancing / retreating operation of the guide and aligns the cutting position with the cutter.
[0013]

For example, the driving pulley, the driven pulley, and the pulley belt are combined, and the driving force of the motor 16 is transmitted to the input conveyor 2 through the driving pulley, the pulley belt, and the driven pulley in this order.
[0018]
As shown in FIG. 1, each guide 3 is attached to the tip of the rod of the guide advance / retreat cylinder 17 so that it can advance and retract with respect to the bail B. As shown in FIG. 4, the cylinders 17 each include an encoder 18.

[0020]
The take-out conveyor 5 is moved forward and backward with respect to the cutting table 1 by a take-out conveyor advance / retreat cylinder 20 (see FIG. 4) and is rotated by a take-out conveyor drive motor 21 (see FIG. 4). . Note that transmission of the driving force of the motor 21 to the take-out conveyor 5 is achieved by a conventionally known driving force transmission mechanism. For example, a driving pulley, a driven pulley, and a pulley belt are combined, and the driving force of the motor 21 is transmitted to the take-out conveyor 5 via the driving pulley, the pulley belt, and the driven pulley in this order.
[0021]
In FIG. 4, reference numeral 22 denotes a control circuit, which includes a CPU 221 that controls the control center, a RAM 222 that stores data and the like, and a ROM 223 that stores a program, and controls according to the program stored in the ROM 223. The CPU 221 of the control circuit 22 is given the output of the encoder 18 built in each guide advance / retreat cylinder 17, while the CPU 221 is based on the encoder output and the like, and the motors 8, 16, 21 and the cylinders 15, 17. , 19, 20 are controlled.
[0022]
The RAM 222 stores a data table 23 (see FIG. 5). In this data table 23, as shown in FIG. 5, the division mode for each bale B input in the cutting order of the bale B is registered in relation to the bale brand, the required dose per batch, and the total kneading amount. ing. In addition, the data table 23 shown in FIG. 5 is created on the assumption that the bale brand is AAA polymer, the required dose per mixed batch is 30 kg, and the total kneading amount is 20 batches, When using the remainder of the previous time in order 13 and 14 or later, it is necessary to add and register positive data that can also be partially corrected.
[0023]
Next, the operation of the bale cutting device will be described.
First, the bale B is put on the cutting table 1. Specifically, the CPU 221 of the control circuit 22 outputs drive signals to both the loading conveyor drive motor 16 and the conveyor belt drive motor 14. Then, both the motor 16 and the motor 14 are driven, and the input conveyor 2 and the conveyor belts 131, 132, 133, and 134 are rotationally driven in the conveyance direction F. As a result, the bale B is loaded onto the cutting table 1 from the loading conveyor 2. When the bale B is placed on the cutting table 1, the CPU 221 outputs a stop signal to both the motor 16 and the motor 14. Then, both the motor 16 and the motor 14 are stopped, and the rotation of the input conveyor 2 and the conveyor belts 131, 132, 133, and 134 is stopped.
[0024]
Next, the bale B is divided and cut into a plurality of pieces on the cutting table 1. Specifically, the CPU 221 outputs an extension signal to the guide advance / retreat cylinder 17. Then, each rod of the cylinder 17 extends, and the guide 3 is advanced to pinch the bale B along its length direction. At this time, the output of each encoder 18 built in the cylinder 17 is input to the CPU 221. Then, the CPU 221 measures the bale length L (see FIG. 6) based on the encoder output, and determines the division mode of the loaded bale B with reference to the data table 23 stored in the RAM 222.
[0025]
In the case of the mode in which the determined division mode is cut only along the width direction of the bail B, that is, the two division mode shown in FIG. 6A and the three division mode shown in FIG. Using the division mode as a parameter, the CPU 221 obtains a cutting position along the width direction of the bail B based on the measured bale length L. Based on the obtained cutting position along the width direction of the bail B, the CPU 221 outputs an extension signal to one cylinder 17 and outputs a shortening signal to the other cylinder 17. Then, the rod of one cylinder 17 extends and the rod of the other cylinder 17 shortens. Accordingly, the cutting position along the width direction of the bail B on the cutting table 1 is moved directly below the cutter 4 and onto the first cutting board 10 while sandwiching the bail B with the guide 3. Thereafter, the CPU 221 outputs an extension signal to the cutter lifting cylinder 19. Then, the rod of the cylinder 19 is extended and the cutter 4 is lowered. Thereby, the bale B is cut along the width direction.
[0026]
On the other hand, the discriminated division mode is cut along the width direction of the bail B and the length direction orthogonal to the width direction, that is, the four division mode shown in FIG. 6C, 6 shown in FIG. 6D. In the case of the dividing mode and the 9-dividing mode shown in FIG. 6 (e), first, a series of operations related to cutting along the width direction of the bale B is performed to cut the bale B along the width direction. Thereafter, the CPU 221 outputs a shortening signal to both the input conveyor advance / retreat cylinder 15 and the takeout conveyor advance / retreat cylinder 20. Then, the rods of the cylinder 15 and the cylinder 20 are shortened, and both the input conveyor 2 and the take-out conveyor 5 are moved back to the dotted line positions shown in FIG. Next, the CPU 221 outputs a normal rotation signal to the cutting table rotation motor 8. If it does so, the motor 8 will rotate forward and the cutting table 1 will rotate 90 degrees forward. Subsequently, the CPU 221 outputs an extension signal to the guide advance / retreat cylinder 17. Then, each rod of the cylinder 17 extends, and the guide 3 is advanced to sandwich the bale B in the width direction. At this time, the output of each encoder 18 built in the cylinder 17 is input to the CPU 221. Then, the CPU 221 measures the bale width W (see FIG. 6) based on the encoder output. The CPU 221 determines the cutting position along the length direction of the bail B based on the measured bale width W using the previously determined division mode as a parameter. Based on the obtained cutting position along the length direction of the bail B, the CPU 221 outputs an extension signal to one cylinder 17 and outputs a shortening signal to the other cylinder 17. Then, the rod of one cylinder 17 extends and the rod of the other cylinder 17 shortens. Accordingly, the cutting position along the length direction of the bail B on the cutting table 1 is moved directly below the cutter 4 and onto the second cutting board 1 while sandwiching the bail B with the guide 3. Thereafter, the CPU 221 outputs an extension signal to the cutter lifting cylinder 19. Then, the rod of the cylinder 19 is extended and the cutter 4 is lowered. Thereby, the bale B is cut | disconnected along a length direction.
[0027]
Finally, the divided and cut bale B is taken out from the cutting table 1 and a new bale B is put on the cutting table 1. Specifically, the CPU 221 outputs a reverse rotation signal to the cutting table rotation motor 8. Then, the motor 8 rotates in the reverse direction, and the cutting table 1 is reversely rotated by 90 ° to return to the original position. Next, the CPU 221 outputs an extension signal to both the input conveyor advance / retreat cylinder 15 and the take-out conveyor advance / retreat cylinder 20. Then, the rods of the cylinder 15 and the cylinder 20 extend, and both the input conveyor 2 and the take-out conveyor 5 move forward to the position indicated by the solid line shown in FIG. 1 and return to their original positions. Thereafter, the CPU 211 outputs a drive signal to the three members of the input conveyor drive motor 16, the conveyor belt drive motor 14, and the take-out conveyor drive motor 21. Then, the motor 16, the motor 14, and the motor 21 are driven, and the input conveyor 2, the take-out conveyor 5, and the conveyor belts 131, 132 and 133, 134 are rotationally driven in the conveyance direction F. Thereby, the cut bale B moves from the cutting table 1 to the take-out conveyor 5, while the new bale B moves from the input conveyor 2 to the cutting table 1.
[0028]
As described above, in the bale cutting device according to the present embodiment, unlike the prior art, the bale is cut on the cutting table 1 instead of cutting the bale while feeding the bale toward the feed direction. Measurement operation, alignment operation between the cutting position of the bale B and the cutter 4, and cutting operation of the bale B can be performed. Therefore, a stopper mechanism for stopping the bale cutting position directly under the cutter, which is an essential requirement in the prior art, is not required. As a result, the configuration of the apparatus is simplified.
[0029]
Moreover, the bale B can be cut | disconnected along the length direction orthogonal to a width direction and a width direction by enabling the cutting table 1 to rotate 90 degrees. Therefore, the freedom degree of the division | segmentation aspect of the bale B increases. As a result, the bale B can be cut finely.
[0030]
Furthermore, the bale B is also cut based on the measurement data and the division mode data stored in the data table 23 created in consideration of the bale brand, the required dose per batch, and the total kneading amount. It is like that. For this reason, the degree of freedom in determining the input of the bale material in the mixing step is increased. As a result, the mixing operator can perform the kneading work while cutting the bale B.
[0031]
The present invention is not limited to the above embodiment. For example, in the embodiment, a configuration has been described in which the advance and retreat operations of the input conveyor 2 and the take-out conveyor 5 are achieved using fluid pressure. However, mechanical means using a feed motor, a feed screw, a slider, and the like have been described. You may make it achieve. It goes without saying that various design changes and modifications can be made within the scope of the claims of the present invention.
[0032]
【The invention's effect】
As apparent from the above description, according to the present invention, there is an excellent effect that the configuration of the apparatus can be simplified.
