Description

  The present invention relates to a rubber sampling apparatus for collecting a sample piece from a sheet-like kneaded rubber.

  FIG. 3 shows a kneaded rubber processing apparatus equipped with a conventional rubber sampling apparatus 100. As shown in FIG. 3, the kneaded rubber processing device cools the sheet-shaped kneaded rubber 101 extruded from the extruder by passing it through a cooling bar 106, and the cooled kneaded rubber 101 is picked up by a pickup device 102. It is moved to the belt type conveyor 103 to carry the conveyor. Then, after the conveyor is conveyed, the kneaded rubber 101 is hung from the end of the conveyor 103 and is folded and stacked by a stacker 105 that reciprocates in a substantially horizontal direction.

  As shown in FIG. 3, the rubber sampling device 100 includes a cutter and a sampling cylinder for reciprocating the cutter, and is usually disposed at the A position or the B position in the drawing.

  When the rubber sampling device 100 is disposed at the A position, the cutter of the rubber sampling device 100 is sampled close to and away from the kneaded rubber 101 hanging from the end of the conveyor 103 (for example, Patent Document 1). However, when it is arranged at the A position, the rubber is clogged and a stroke of about 500 mm is required as a sampling cylinder.

  On the other hand, when the rubber sampling device 100 is disposed at the B position, the rubber sampling device 100 is disposed above the conveyor 103, and the cutter of the rubber sampling device 100 is brought close to and away from the kneaded rubber 101 on the conveyor 103. Sampling is required.

  However, since the kneaded rubber 101 is transferred onto the conveyor 103 by the pickup device 102 as described above, the portion of the kneaded rubber 101 conveyed on the conveyor 103 held by the pickup device 102 is overlapped by two or three sheets. become.

  Therefore, in order to avoid interference between the portion of the kneaded rubber 101 overlapped by two or three sheets and the cutter of the rubber sampling apparatus 100, the standby position of the cutter is separated by only a portion overlapped by two or three sheets from the kneaded rubber 101. As a sampling cylinder, a stroke of approximately 300 mm is required.

  Thus, the rubber sampling device 100 can be arranged at the B position rather than the A position to shorten the sampling cylinder stroke. However, even if it is arranged at the B position, it is necessary to stop the conveyor 103 during sampling, so the sampling time becomes a loss time and the productivity decreases.

  Therefore, in view of the above problems, the present invention reduces the stroke of the conveyor by shortening the stroke of the sampling cylinder when the rubber sampling device is arranged at the B position and sampling is performed from the kneaded rubber on the conveyor. It is an object of the present invention to provide a rubber sampling device that can improve productivity by shortening the length as much as possible.

  The present inventor has found that the above problems can be solved by the invention shown in the following claims, and has completed the present invention.

This is a rubber sampling device.

  According to the present invention, by shortening the stroke of the sampling cylinder, the stop time of the conveyor can be shortened as much as possible to improve productivity.

It is a top view which shows one Embodiment of the rubber sampling apparatus which concerns on this invention. It is a principal part enlarged front view of the cutter unit which shows one Embodiment of the rubber sampling device which concerns on this invention. This is a kneaded rubber processing device equipped with a conventional rubber sampling device.

  Hereinafter, based on an embodiment, the present invention will be specifically described with reference to the drawings.

  FIG. 1 is a plan view showing an embodiment of a rubber sampling apparatus according to the present invention. FIG. 2 is an enlarged front view of a main part of a cutter unit showing an embodiment of a rubber sampling device according to the present invention.

1. Overall Configuration of Rubber Sampling Device As shown in FIGS. 1 and 2, the rubber sampling device 10 is a device that collects a sample piece from a sheet-like kneaded rubber A conveyed by a conveyor 20, and includes a cutter unit 30 and a conveyor. A turning mechanism 40 for turning the cutter unit 30 between a sampling position above the conveyance path of the kneaded rubber A conveyed by the apparatus 20 and a standby position on the side of the conveyance path is provided as a main component.

2. Configuration of Conveyor As shown in FIG. 1, the conveyor 20 includes an upstream belt conveyor 21, a downstream belt conveyor 22, and roller conveyors 23 disposed between the upstream and downstream belt conveyors 21 and 22. It consists of

  The conveyor 20 is arranged so that the downstream side faces upward, thereby conveying the kneaded rubber A obliquely upward.

  The transport rollers 23 b to 23 h of the roller conveyor 23 are formed shorter than the rollers 21 a of the upstream belt conveyor 21 and the rollers 22 a of the downstream belt conveyor 22. Thereby, a space portion 24 without rollers is formed between the belt conveyors 21 and 22 on the upstream side and the downstream side and on the side of the roller conveyor 23.

  For this reason, when the kneaded rubber A is conveyed from the upstream belt conveyor 21 through the roller conveyor 23 to the downstream belt conveyor 22, one side of the kneaded rubber A passes over the space portion 24 without the roller. Will do.

3. Cutter Unit As shown in FIG. 2, the cutter unit 30 includes a cutter 31, a receiving blade 32, a sampling cylinder 33, a sample piece discharge cylinder 34, and a frame 35 that supports these components. ing. Note that the cutter unit 30 is disposed in an inclined manner corresponding to the inclination of the conveyor 20.

  The sampling cylinder 33 reciprocates the cutter 31 in a direction substantially perpendicular to the surface of the kneading rubber A, and approaches and separates one side of the kneading rubber A passing over the space portion 24 without a roller. Sometimes the cutter 31 punches a part of one side of the kneaded rubber A and collects a sample piece. At this time, the receiving blade 32 is positioned below one side of the rubber A and directly receives the rubber A. For this reason, the belt is not damaged as in the conventional configuration in which the belt of the conveyor is replaced with the receiving blade.

  The sample piece discharge cylinder 34 is disposed between the cutter 31 and the sampling cylinder 33. When the cutting edge of the cutter 31 is circular or the like, the punched sample piece remains in the cutter 31. Therefore, the sample piece remaining in the cutter 31 is pressed downward by the sample piece discharge cylinder 34 from the inside of the cutter 31. Eliminate sample pieces.

4). As shown in FIG. 1, the turning mechanism 40 is disposed on one side of the conveyor 20 (outside of the space portion 24 without rollers). The turning mechanism 40 is a crank that converts the reciprocating motion of the support shaft 41, the turning cylinder 42, and the turning cylinder 42 into the turning motion of the cutter unit 30 in order to mount the frame 35 of the cutter unit 30 so as to freely turn. 43.

  The swivel mechanism 40 swivels the cutter unit 30 between a sampling position above the space portion 24 where there is no roller of the conveyor 20 and a standby position outside the transport path. In this embodiment, the standby position is a position that is turned by approximately 90 ° from the sampling position, and is set to a position on the outer side of the conveyor 20.

5. Description of Operation of Rubber Sampling Device (1) The rubber sampling device 10 is configured as described above, and the kneaded rubber A is conveyed onto the conveyor 20 from a pickup device (not shown). The conveyance of the kneading rubber A is stopped at a position where the portion other than the overlapped portion is located above the space portion 24 where there is no roller. Next, the turning cylinder 42 is retracted, and the cutter unit 30 at the standby position is turned to the sampling position. Then, the sampling cylinder 33 is extended and the cutter 31 is pressed against the kneaded rubber A on the conveyor 20 to collect a sample piece.

(2) Next, after the sampling cylinder 33 is retracted, the turning cylinder 42 is extended to return the cutter unit 30 at the sampling position to the standby position.

(3) Then, the sample piece discharge cylinder 34 is moved forward and backward to remove the sample piece remaining on the cutter 31, and the conveyance of the kneaded rubber A by the conveyor 20 is resumed.

6). Effect (1) of the present embodiment As described above, the rubber sampling apparatus 10 according to the present embodiment turns the cutter unit 30 from the sampling position to the standby position and retracts it. Interference between the overlapping portion of the three sheets and the cutter 31 of the cutter unit 30 can be prevented.

  For this reason, it is not necessary to separate the standby position of the cutter (the position at which the cutter is separated from the kneading rubber A at the sampling position) by only a portion overlapped by two or three sheets from the kneading rubber A, and the stroke length of the sampling cylinder 33 is eliminated. The sampling time can be shortened. As a result, the stop time of the belt conveyor can be shortened and productivity can be improved.

(2) The inventor has confirmed that the sampling time can be shortened by about 4 seconds / time compared to the conventional apparatus by using the rubber sampling apparatus of the present embodiment.

(3) Further, in order to punch out a part of one side of the kneaded rubber A passing over the space part 24 without a roller as described above, and to collect a sample piece, the conventional method uses a conveyor belt instead of a receiving blade. The belt is not damaged as in the case of the configuration.

  While the present invention has been described based on the embodiments, the present invention is not limited to the above embodiments. Various modifications can be made to the above-described embodiments within the same and equivalent scope as the present invention.
