Description

  The present invention relates to a candy paper sticking device for automatically winding and sticking candy paper on a box-like object to be attached.

  Conventionally, a device disclosed in Japanese Patent Laid-Open No. 6-32324 has been known as a device for automatically winding and pasting candy paper around a box-like body to be adhered. This device lifts and moves the box-shaped body to which the candy paper is to be attached by an elevator, and arranges the supply path of the candy-paper in the middle of the hoistway to raise the box-shaped body while raising the box-shaped body. It is designed to roll around with a turtle paper on the top. That is, the paper sheets are stacked and stored in the stocker unit, and are fed one by one onto the supply path by the paper feeding mechanism, and the fed paper sheets are conveyed to the hoistway by a suction conveyor disposed horizontally along the supply path. It is like that. The suction belt of the suction conveyor is provided with continuous paper paper holding means for holding the paper paper with the leading edge of the paper. It is designed to wait in opposition to. After holding the leading edge of the funnel paper fed out on the supply path between the funnel paper holding means, the suction conveyor is operated in the funnel paper supply direction, and the funnel paper is pulled out to the hoistway and then to the suction belt. Adsorption is performed to release the funnel paper holding means.

  Further, while supplying the funnel paper toward the hoistway with the suction belt, the paste is sprayed and applied to both sides of the funnel paper from the spray nozzle.

In addition, the hoistway is provided with a pair of inverted L-shaped folding guides having a vertical piece that contacts the side surface of the box-like body and a horizontal piece that slides on the bottom surface, connected to the drive unit that expands and contracts in two stages, When the side of the box-like body rises to the position opposite to the vertical piece, the first-stage protrusion is made and the paper sheet is folded along the side of the box-like body. When the height rises to a height of 2 mm, a second stage of protrusion is performed, and both side portions of the candy paper are folded and stuck along the lower surface of the box-like body.
JP-A-6-32324

  However, in the paper paper sticking device in the above publication, when the paper is adsorbed by the suction belt, the left and right sides of the paper are misaligned and may be wound obliquely when wound around the box-shaped body. was there.

  That is, when paper sheets stacked and stored in a stocker in a stacked state are fed out by a paper feed mechanism composed of a large number of rollers or the like and fed onto the supply path, the paper sheets are placed on the left and right sides thereof in the front and rear directions. However, as shown in the apparatus of the publication, the tip of the drawn-out paper is sandwiched between the funnel paper holding means connected to the suction belt of the suction conveyor and the middle of the hoistway. If it is pulled out to a predetermined position and is attracted and locked by a suction belt at the predetermined position, the foldable paper will be wound around the box-shaped body obliquely without correcting the slight deviation. turn into. If the left and right sides of the paper are wound in such a manner, even if the deviation is subtle, it will be noticeable and the appearance will be significantly impaired.

  In addition, since the suction belt itself is elastic, there is a concern that a slight left / right shift caused by this elasticity may occur during the transport operation, and there is room for improvement in terms of durability due to deterioration over time. Is left behind.

  The present invention has been made in view of the above circumstances, and the object of the present invention is to correct the misalignment and correct the misalignment of the hoistway even if the misalignment occurs on both the left and right sides of the funnel paper fed out from the stocker. It is an object of the present invention to provide a candy paper sticking device which can be supplied while being attracted and locked in a stretched state at a predetermined position in the middle, and can be rolled up with good appearance.

  In order to achieve the above-mentioned object, the invention according to claim 1 of the present application is directed to a transport conveyor that transports a box-shaped object to be pasted with candy paper, and a target to be supplied supplied from the transport conveyor. A funnel paper sticking means that pushes the kimono upward through an elevator while passing through the sticking mechanism and sticks the funnel paper on the upper surface of the adherend in a body-wound state, and holds it in the upper stacker portion; A funo paper sticking device comprising: a funo paper feeding device that is provided directly below a sticking mechanism portion of the paper sticking means and that feeds the paper from a side while holding the paper in a stretched state. However, there is provided a conveyance guide which is provided at the extension end of the conveyance guide with the conveyance end facing directly below the sticking mechanism portion, and 1 A sheet feeding mechanism that feeds the sheets one by one to a predetermined position on the conveyance guide; A feeding mechanism that abuts against both side portions of the trailing edge of the conveying direction on the paper sheet fed to a predetermined position on the card and pushes it toward the conveying end side of the conveying guide, and the conveying end of the conveying guide A suction conveyance mechanism section that sucks both sides in the conveyance direction of the funnel paper that has been pushed to the side and feeds it directly under the sticking mechanism section in a stretched state.

Then, it engages with the lower surface of the adherend 6 and holds the adherend 6. That is, the stacker portion 18 is located above the stopper piece 188.

  The lower surface folding means 170 of the sticking mechanism portion 16 is provided such that the upper surface of the bent piece 182 at the lower end of the L-shaped arm 178 matches the height of the upper corner portion of the stopper piece 188. ing. That is, the actuator 172 of the lower surface folding means 170 is actuated while the adherend 6 is locked to the stopper piece 188 and the actuating rod 174 is extended inward, and the lower end of the L-shaped arm 176 is bent. An abutting piece 184 rotatably supported by the piece 182 is brought into contact with the lower surface of the adherend 6, and both end portions of the paper 4 are pressed while being bent following the lower surface of the adherend 6. It is made to adhere and sticks with the liquid paste applied there. At this time, when the operating rod 174 is extended, the L-shaped arm 178 and the contact piece 184 rotate together, and the contact piece 184 comes into soft contact with the lower surface of the adherend 6. Yes.

  Then, the adherends 6 are sequentially raised from below and are synchronized with each other, and are successively supplied directly under the sticking mechanism 16 in a state where the paper 4 is stretched, and the paper 4 is attached to the paste 6. Is stored in the stacker unit 18 while being wound around. Further, when a predetermined number of adherends 6 are stored in the stacker portion 18, they are sequentially transferred onto the carry-out conveyor 20 from the upper end portion via the shooter 22.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic explanatory diagram illustrating a flow of a box-like object to be adhered that moves inside the apparatus, and a sheet of dough paper, showing the candy paper sticking apparatus according to the present invention. It is a top view which shows the candy paper sticking apparatus which concerns on this invention. It is a front view of the apparatus shown in FIG. FIG. 4 is a left side view of FIG. 3. Front view showing the internal structure, FIG. 6 is a left side view of FIG. 5. (A)-(c) is a figure which shows in order the state by which the wrapping paper is stuck and wound around by the sticking mechanism part of the stuffing paper, (A), (b) is the top view and side view which show roughly the supply state of the funnel paper from a stocker part to the sticking mechanism part. It is a figure which shows sequentially the operation state of the glue application | coating means which apply | coats glue to a candy paper.
