Description

  TECHNICAL FIELD The present invention relates to a film material joining apparatus that joins a thin plate-shaped film material used and a newly supplied thin-plate-shaped film material by abutting each other at their end faces.

  Conventionally, for example, a film material in a packaging machine is continuously wound around a core of a reel to form a large-diameter coil, and is disposed in a film supply unit of the packaging machine. When the remaining amount of the film material wound around the reel decreases, the film material wound around a new reel is used in exchange. At this time, the old film material in use is cut in the vicinity of the end position, and then joined and joined to the starting end portion of the newly wound film material. In the conventional joining of film materials, generally, an end portion of an old film material and a starting end portion of a new film material are bonded to each other. However, when the overlapped joint portion passes through a narrow place in the route through which the film material is fed, a feeding trouble may occur at that place. For this reason, it has been necessary to join the joint portions in a flat shape so that the film materials do not overlap and become thick.

Conventionally, a technique for joining in a flat shape is disclosed in Patent Document 1. According to this, when an old paper material and a new paper material are joined, the machine in use is temporarily stopped and adhered by an adhesive tape on a horizontal plane.
JP-A No. 2004-161440 (see pages 4-8, FIG. 1)

  However, the film material joining apparatus disclosed in Patent Document 1 joins two paper ends (the end of the old paper and the start of the new paper) while affixing them with an adhesive tape. At times, it was necessary to stop the machine once as described above. When the machine is stopped, the operation time of the machine is reduced, and the productivity is lowered. Therefore, it has been desired to join the film material while the machine is in operation.

The present invention solves the above-mentioned problems, and the first object is to be able to join new film materials without stopping the machine, and the second object is to overlap the joining surfaces.

  Further, as shown in FIG. 1, the buffer stage 25 is provided with a plurality of suspension rollers 251 in order at an upper position and a lower position to form a suspension roller group 251 so that the film material F can be stored on this stage. The upper suspension roller 251U and the lower suspension roller 251D are suspended in this order. The suspending roller group 251 moves up and down according to the consumption of the film F, whereby the feeding speed of the film F is controlled by the encoder 28.

  Next, the operation of the device M configured as described above will be described.

  First, the first feeding line 3 arranged on the right side in FIG. 1 constitutes the main feeding line 20 and feeds the film material F from the supply reel 4 to the machined portion of the machine body. On the other hand, in the second feed line 3A, the adhesive tape T is attached to the start end of the new film material FN, and the start end of the new film material FN is fixed on the second rotating roller 11A. set.

  In addition, this set in the second feeding line 3A is performed while the machine is in operation. First, a new film material FN is attached to the supply reel 4A, and then an adhesive tape is attached to the start end. The new film material FN has the front and back surfaces reversed with respect to the film material F in use. That is, if the film material F in use shows the front surface on the transport table 6, the new film material F shows the back surface on the transport table 6. As a result, the old and new film materials F joined together form the same surface.

  At this time, first, as shown in FIG. 7, the registration mark LM formed on the side end portion of the new film material FN is aligned with the registration mark pointer claw 15 arranged on the transport table 6 to position the film material FN. do. By positioning the registration mark LM, the movement reference of the film material F at the time of joining (when the new film material FN is switched as the film material F in use) can be used.

  And as shown in FIG. 8, it sticks to the half length of the adhesive tape T to the starting-end part back surface side of the film material FN. The starting end of the film material FN (tip of the adhesive tape T) is pulled out to the position of the marking line K formed on the second rotating roller 11A, and further, the second rotating roller 11A is rotated as shown in FIG. Then, the second marking line K <b> 1 formed on the second rotating roller 11 </ b> A is aligned with the pointer 16 disposed on the transport table 6. As a result, the new film material FN moves to a predetermined position (joining position with the film material F in use). When air is injected into the second rotating roller 11A by an air supply device (not shown), a vacuum (not shown) is obtained. By switching the valve of the apparatus, the film material FN is adsorbed through the adsorption holes 111. The film material FN is fixed to the second rotating roller 11A by clamping the second rotating roller 11A with a clamper (not shown).

  In the second feeding line 3A, the presser guide 7A disposed on the transport table 6 is in an open state, and the guide member 13A is in a removed state.

  In the first feeding line 3, when the remaining amount of the film material F in use decreases, the film decrease notification sensor 26 detects and notifies that “the film F in use will soon be exhausted”. After the warning sensor 26 is activated, when the end tape detection sensor 27 detects the end tape ME formed on the film material F, the signal is sent to the servo motor 24. The servo motor 24 receives this signal, switches to low speed operation, and rotates the feeding roller 23 at low speed.

  When the tape end mark ME is detected, after the registration mark sensor 29 detects the registration mark LM in the film material F, the cutter 81 of the cutting device 8 is once positioned at an intermediate position of the registration mark LM immediately after. To stop. Then, the cutter 81 moves upward by the operation of the cylinder 82 and cuts the film material F. Thereafter, the feeding roller 23 is operated to move the film material F at a low speed, and the movable roller (first rotating roller 11) is moved to the fixed roller (second rotating roller 11A) by the action of the air cylinder 12. Move instantly toward.

  The slow movement of the film material F after the cutting of the film material F and the moving speed of the movable side roller (first rotating roller 11) are accurately calculated and controlled by the control unit, and the movable side roller is the fixed side roller. At the time of pressure contact, the end face of the cut film material F in use and the start face of the new film material FN that is waiting are bonded to the adhesive tape at a position where it can be abutted almost without any gap.

  When the new film material FN is joined to the old film material F, the second supply line side is sent as the main supply line 20. Then, the movable roller returns to the original position, and the first rotating roller 11 and the second rotating roller 11A are separated. When the two rotating rollers 11 are separated, the servo motor 24 returns to normal operation again.

  In the meantime, in the processing section of the machine, the film material F stored in the buffer stage 25 is sent out and normal processing is performed.

  In the buffer stage 25, since the film material F stored in the buffer stage 25 is used while the old and new film materials F and FN are joined, the lower suspension roller 251D is raised. After the old and new film materials F are joined, it is desirable that the feeding roller 23 is rotated at a higher speed than the normal operation for a while so that a large amount of the film material F on the buffer stage 25 can be stored. In this case, the lower suspension roller 251D is lowered.

  As described above, the film material joining apparatus (device) M according to the embodiment joins the first feeding line 3 for feeding the old film material F being used to the joint 10 and the new film material FN to the joint 10. Since the second feed line for feeding to the second feed line is provided so that it can be used alternately, and the buffer stage 25 for storing the film material F is provided, the machining portion of the machine main body is provided. The machine body can be operated without stopping the operation, and productivity can be improved.

  Further, when the remaining amount of the film material F in the first feeding line 3 is reduced, the film material decrease notice sensor 26 detects it, and the tape end detection sensor 27 detects the end edge tape ME, and the transport table 6. The upper film material F is moved slowly.

  Further, when the registration mark sensor 29 is actuated, the film material F is cut by the cutter 81, the first rotation roller 11A is rotated by a predetermined angle, and the fixed side roller (first rotation roller 11) of the movable side roller (first rotation roller 11). The control device controls the instantaneous approaching movement to the second rotating roller 11A), so that there is no gap between the end face of the old film material FN that has been cut and the start edge of the new film material FN that is waiting. Can be joined together to match.

  Thus, the film material F can be formed on a flat surface, and can be fed without trouble even in a narrow place formed in the main feeding line 20 and the machine body.

  In addition, the joining apparatus of the film material of this invention is not limited to said form. For example, the new film material FN in the second feed line 3A can be automatically fixed to the second rotating roller, and both rotating rollers simultaneously move the movable roller closer during joining. You can also.
