[Detailed description of the invention]

[0001]

This invention is used for laying a bag made of synthetic resin or paper inside a box having an open top surface made of an appropriate material such as corrugated paper or synthetic resin. Bag laying device to be used.

[0002]

2. Description of the Related Art Conventionally, as a bag laying apparatus for laying a packaging bag in a cardboard box as described above, for example, as shown in FIG. 11, a synthetic resin tubular film f wound in a roll shape is used. Is fed in the vertical direction, the tubular film f is welded in the width direction by the heating head 70 arranged at the upper stage at the same position, and the tubular film f is stretched in the width direction by the cutting cutter 71 arranged at the lower stage at the same position. By cutting, one packaging bag F is separated and formed. At the same time, the left and right adsorbers 7 arranged below the same position.
The two sides of the opening side of the packaging bag F are sucked and held by 2 and 72, and the adsorbers 72 and 72 are separated in the left-right direction to open the inlet Fa of the packaging bag F to an appropriate size. Thereafter, the packaging bag F is horizontally moved to the upper side of the cardboard box B while the packaging bags F are being sucked and held by the left and right suction elements 72, 72, and the suction holding by the respective suction elements 72, 72 is released, and the packaging bag F is moved to the cardboard box. There is a device to be inserted into box B.

[0003]

However, the inlets Fa of the hanging packaging bag F as described above are connected to the left and right adsorbers 7 respectively.
When the suction bag 2 is held by suction, the posture of the packaging bag F is unstable. Therefore, when the left and right adsorbers 72, 72 are brought into close contact with the opening Fa of the packaging bag F, the opening Fa of the packaging bag F is used. The suction positions of the suction members 72 and 72 tend to shift, and the suction operation and the opening operation by the suction members 72 and 72 may be erroneous. In addition, the packaging bag F sucked and held by each of the adsorbers 72, 72 falls during the movement, or the input port F of the packaging bag F
For example, it is difficult to reliably insert the packaging bag F into the cardboard box B because a is closed. After the bag is inserted, the laid state of the packaging bag F inserted in the cardboard box B must be corrected by the operator, which has a problem that the working efficiency is poor.

[0004] In view of the above problem, the present invention is designed to be stored in a storage section.
By taking out the bag from the bottom side of the bag and holding the inlet of the bag and standing upright, the inlet of the bag can be accurately and reliably sucked and held, and the bag is laid. An object of the present invention is to provide a bag laying device capable of stably performing an operation, saving labor and improving efficiency of the laying operation.

[0005]

SUMMARY OF THE INVENTION This invention is in the open position the front stage of the bag opening means, one by one of the bag body which is formed in a size which is laid on the box body portion of the bag body bottom Adsorbent
A bag supply means for sucking and supplying the bag to the next stage, and placing the bag supplied by the bag supply means on a mounting table.
The bag laying device is characterized in that it is a bag laying device provided with a bag erecting means for holding the charging port side of the bag body on a table and raising the bag body in a posture in which the charging port side is upward.

[0006]

[Action] This invention is Kyuchakuko drives the bag supply means, the bottom side of the bag body one by one of the bag body formed in the appropriate size
Then , the bag is supplied from the bottom side, and then the bag erecting means is driven to place the supplied bag on a mounting table.
The charging port side of the bag body is held on the mounting table, and the bag body stands upright so that the charging port side faces upward. Next, by driving the bag opening means, the input port of the bag body standing upright is sucked and held by each of the left and right adsorbers and opened, and the bag inserting means is driven to assemble the box assembled in the top open form. Since the bag body is vertically inserted and laid inside the body in an open state, the work of laying the bag body can be stably performed.

[0007]

[Effect of the invention] According to the invention, the bag of the storage section is
Since the bag is taken out from the bottom side and held in the upward position while holding the charging port side of the bag, the position and posture of the bag at the time of bag suction are stabilized, and the bag is inserted by each adsorber of the bag opening means. The mouth can be accurately and reliably sucked and held. Moreover,
Unlike the conventional device, the bag does not drop during the movement or the opening of the bag is closed, and the work of laying the bag inside the box with the bag open can be performed stably. Can save labor and improve efficiency.
