Description

Direction transfer device for agricultural bag production device

The present invention relates to a device for manufacturing a bag of a mesh type used for packaging, transporting and storing various agricultural products, and relates to an apparatus for laterally conveying a fabric cut to a length through a cutting device for sewing a cutting portion. will be.

As is well known, in order to manufacture a bag for packaging agricultural products, the fabric is rolled into a cylindrical shape and rolled in a roll shape to cut a certain length first, and one side is sealed and manufactured in an envelope form.

Conventionally, in order to manufacture such a bag, it was cut and sewn by hand, but in recent years, an attempt has been made to automatically manufacture a bag. After cutting the rolled fabric roll to one side, the cut part is cut on the sewing machine. Since it must be sewn while passing through, it must be transported in a direction perpendicular to the direction in which it was first released.

However, the development of a device for quickly and precisely transferring the cut fabric as described above has not been easily achieved, which has been a major problem of automatic bag production. However, some attempted lateral transfer devices have a complicated structure and a failure. In addition, it was not a frequent and accurate transfer at right angles, not at a right angle, or at a time because two sheets were overlapped to transfer each other.

According to the above problem, this paper is designed to be moved up and down at the same time as it rotates while installing the rubber-coated feed roller in the cut unit. It was developed for the purpose of enabling trouble-free operation.

The configuration of the redirection transfer device (e) of this paper is installed on the conveyor belt 10, which is stopped for a while after the fabric 1 is cut by the cutting device (d).

The fixing plate 13 is installed on the side of the conveyor belt 10, that is, on the upper side of the sewing unit (bar) by using the bracket 11 and the fixing stand 12, and the LM guide 14 is installed on the front of the fixing plate 13 to lift the plate. Install the steel plate 15 on the top of the center of the fixing plate 13 The cylinder 17 is fixed to the upper surface of the mounting plate 16 by fixing the mounting plate 16 of the "type, and then the rod 17 'is fixed to the upper surface of the lifting plate 15.

The guide rods 19 were fixed to the left and right lifting plates 15 of the portion where the rod 17 'of the cylinder 17 was fixed by using the fixing pieces 18, and the springs 20 were attached to the guide rods 19. After insertion was configured to penetrate the guide piece 21 attached to the fixed plate (13).

On the front surface of the elevating plate 15, two support holes 22 are installed to install a feed roller 23 coated with a rubber jacket 23 'with fine projections, but a belt pulley 24 is provided at the center of the feed roller 23. ) To hang the rubber belt (25),

The frame 9 on the opposite side of the conveyor belt 1 is provided with a support 30, and then a belt pulley 32 that is rotated by a motor 31 is installed to hang the rubber belt 25 described above. The rotation of the feed roller 23 was configured to rotate.

In the drawings, reference numeral 40 denotes an inlet roller for pulling the fabric, 41 a sewing machine, 42 a roller for rotating the conveyor belt 10, 43 a support plate for supporting the conveyor belt 10, and 44 a fabric with a sewing part (bar). Conveyor belt 45 for entering (1), 45 is a conveyor belt for conveying the bag (1 ') to the discharge section.

In this proposal of the above configuration, the fabric roll 1a is released from the fabric supply unit a, and the fabric waiting unit 4 waits for a predetermined amount, and then the inlet roller 40 of the fabric inlet unit (C) repeats by a predetermined length. The fabric is pulled into the cutting unit (d) and the cutting unit (d) is cut to a certain length, and at the same time, the redirection feeder (e) of the present article starts to operate.

When the cutting operation of the cutting part (d) is completed in the above state, the cylinder 17 operates to lower the lifting plate 15, and the LM guide 14 helps to make the lifting plate 15 move smoothly and accurately. As the guide rod 19 descends, the spring 20 spanned over the guide piece 21 is compressed.

When the transport roller 23 descends and comes into contact with the fabric 1 stationary on the conveyor belt 10, the fabric 1 cut by the rotation of the transport roller 23 is pushed by the sewing part (bar) next to it. In this case, even if the center distance between the belt pulley 32 and the conveying roller 23 is slightly changed, the power transmission and lifting action can be continuously performed without problems because the connected power transmission means is a rubber belt 25.

After the transfer of the original fabric 1, the rod 17 'of the cylinder 17 is returned to raise the lifting plate 15, and at this time, it helps to smoothly rise due to the restoring force of the compressed spring 20.

At the same time as the transfer operation is finished as described above, the inlet roller 40 of the inlet unit (c) draws the fabric 1 again a certain length, and repeats the process of transferring the fabric 1 after cutting again. will be.

The fabric 1 entered into the sewing device (bar) is one side is sewn by the sewing machine 41, the bag 1 'is completed, and the thread cutting part (sa) cuts the thread connected to the bar part. Then, the bag manufacturing is completed by continuously discharging the bag through the transfer unit (H) and the discharge unit (I).

As described above, since the lateral transfer operation of the cut fabric 1 is precisely and smoothly performed even with a simple configuration, it is possible to further improve the performance of the device for automatically manufacturing the bag. It is a useful design that can be expected to improve.
