Description

  The present invention relates to a conveyor that can supply the same article to a certain position at a certain timing, and more particularly to a chain conveyor that can be used for processing envelopes.

  Conventionally, a person who has received an envelope has to tear the envelope with a finger or open it with a scissors or a cutter. And the unsealed part could be smashed, and even the notepaper inside was damaged. For this reason, when opening, it was necessary to open carefully.

  As an envelope that can be easily opened by solving such a problem, for example, an envelope described in Patent Document 1 is known. As shown in FIG. 6, the envelope 110 described in this document is provided with a dividing hole 119 in which a cutting thread 117 is glued on a fold line on which a sealed piece is folded and a top end is cut into a triangle. Then, when the upper end portion is cut along the dividing hole 119 and pulled as it is, the fold line is cut and opened by the cutting thread 117 so that it can be opened.

  Patent Document 1 describes a manufacturing method for making such an envelope 110. As shown in FIG. 7, the envelope 110 is processed on the main conveyor 190, and a ruler 191 for placing the envelope 110 at a predetermined position and a cut hole forming machine for forming the cut hole 116. 192, a glue applying machine 193 for applying the glue 143 to the cutting hole 116, a roller 194 for pressing the cutting thread 117 against the broken line to which the glue 143 is applied, a dryer 195 for drying the glue 143, and the cutting thread 117 are cut. A cutter 196 for bending, a folding machine 197 for bending the sealing piece 111, a hole forming machine 198 for forming the dividing hole 119, and the like are described.

  In this case, the envelope 110 is subjected to predetermined processing after being positioned by a ruler 191 formed in a convex shape on the belt. However, it was very difficult to put the envelope 110 into the ruler 191. For example, even if it cuts out by the convex-shaped part of the ruler 191 in order from the bottom of the laminated | stacked envelope 110, a certainty is inferior and a disorder | damage | failure is produced and the envelope 110 is often scattered.

Further, the envelope 110 that can be used is limited to one type of shape determined by the ruler 191, and when processing the envelope 110 having other dimensions, it is necessary to replace the ruler 191 together with the belt. Therefore, the envelopes 110 that can be processed are limited to those prepared with the ruler 191 in advance, and envelopes with non-standard dimensions that do not include the ruler 191 cannot be processed.

Moreover, FIG. 4 has shown the discharge roller of the front-end | tip part. FIG. 5 shows a case where the conveyor according to the present invention is used as an envelope feeder of an envelope processing machine.

  As shown in FIG. 1, a conveyor 1 according to the present invention is a conveyor that supplies articles to a certain position at a certain timing, and a pair of left and right endless chains 20 are provided on a frame body 10. The endless chain 20 is stretched around a ring body 21 provided before and after the frame body 10 and is driven by a motor 22. And the conveyance member 30 provided with the top 31 supported by this pair of endless chains 20 travels at regular intervals. For example, the conveying member 30 is formed by connecting the link plates of the left and right endless chains 20 with groove-type members, and the frame 31 is formed by providing a member protruding at a predetermined position.

  On the upper side of the endless chain 20, an upper flat plate 11 and a guide plate 12 for articles are supported by the frame body 10. The upper flat plate 11 is an article conveyance path, and the article is conveyed while sliding on it. The guide plate 12 guides the article so that the article is conveyed at a fixed position with respect to the left and right directions. The frame 31 of the conveying member 30 is provided so as to protrude from the upper surface of the upper flat plate 11, and conveys the article by contacting the article placed on the upper flat plate 11.

  A major feature of the conveyor 1 of the present invention is that the upper flat plate 11 is inclined in either the left or right direction. The article placed on the upper flat plate 11 receives a force that moves in an inclined direction and is restricted by the guide plate 12. In FIG. 1, since the upper flat plate 11 is inclined to the right side in the traveling direction, the article receives a force to move to the right side, but the movement of the article is restricted by the article coming into contact with the guide plate 12, and the article Is conveyed along the guide plate 12.

  Therefore, the article is always conveyed with its one end abutting against the guide plate 12 and discharged to a certain position. In addition, by causing the endless chain 20 to travel at a constant speed, the conveying member 30 travels at a constant interval and at a constant speed, and the article is discharged at a constant timing. As a result, when the conveyor 1 receives an article, the article is accurately carried out even if a slight deviation occurs (left and right or back and forth) (about ± 10 mm when the article is an envelope).

  The upper flat plate 11 is preferably parallel to the pair of endless chains 20 from the viewpoint of operation and maintenance. Moreover, as shown in FIG. 1, the inclination of the upper flat plate 11 may be one in which the conveyor 1 manufactured in a normal form is inclined as a whole.

  It is also preferable that the upper flat plate 11 is divided into two or more. In particular, as shown in FIG. 1, it is preferable that the top 31 travels between the upper flat plates 11 divided in the left and right directions.

  It is preferable that the guide plate 12 can be moved in the left-right direction. For example, when used as an envelope feeder, envelopes having different sizes can be processed in the same manner by moving the guide plate 12. FIG. 2 shows a case where a small envelope 50 is processed, and FIG. 3 shows a case where a large envelope 50 is processed. By moving the guide plate 12, the portion of the sealing piece to be processed can be set at a fixed position, and the subsequent envelope processing machine can be used in the same manner.

  The conveyor 1 of the present invention preferably includes a sensor 32 that detects the position of the traveling piece 31. By detecting the position of the top 31, it is possible to instruct the timing of paying out the article to the apparatus in the previous process. Similarly, it is possible to instruct the timing for receiving the article to the apparatus in the subsequent process.

  Moreover, when using as an envelope supply machine etc., it is preferable to provide the discharge | emission roller 40 at the front-end | tip part of the upper flat plate 11. FIG. The discharge roller 40 includes an upper roller 41 and a lower roller 42 having the same outer diameter, and it is preferable to rotate both rollers in the opposite direction at the same rotational speed. As a result, it is possible to accurately grasp the envelope and the like, and it is possible to reliably discharge at an accurate timing.

  As described above, the conveyor 1 of the present invention can instruct the timing of dispensing the article to the previous process, and reliably supplies the article to the certain position at a certain timing for the subsequent process. be able to. Then, by changing the position of the guide plate 12, it is possible to easily and quickly cope with articles having different shapes. Moreover, the structure is simple and it can be widely used in many fields.
