Description

[Detailed description of the invention] (Industrial application field) The present invention is a box forming device for packaging individual cup-shaped products having shapes such as cones, trapezoids, and triangular pyramids into boxes. This is related to the improvement of

(Prior Art) FIG. 5 shows a typical example of a conventional box forming apparatus. As shown in the figure, the goods to be packed are 01 in which a predetermined number of conical cup-shaped individual packages (hereinafter referred to as individual packages) are stacked, and the products are placed in a predetermined box on an article supply conveyor 02. It is transported to packing position 03. On the other hand, flat blank sheets (hereinafter referred to as sheets) 05 taken out one by one from the magazine 04 are inserted into the packaging position 03 on the conveyor 02 from the side and are waiting. Then, the accumulated individual packages 01 are fed and stopped.

Subsequently, when it is confirmed that the individual packaged product 01 has been fed, the sheet 05 is lowered with its lower surface supported by the suction cup holder 06 of the lowerator (see Figure 2), and parallel to the lower part of the supply conveyor 02. It is placed at a predetermined position and lowered onto the transport rail 07. Also, when descending, both the front and rear sides of seat 05 are
Each sheet is bent from the fold line by a guide plate (not shown) provided on the machine frame as shown in FIG. Subsequently, when the sheet 05 formed into a substantially U-shape and enclosing the accumulated individual product group 01 is placed on the conveyance rail 07, the case slider 08 moves to the second position.
As shown in the figure, it moves forward on the guide rail 09 (see FIG. 4) using a crank mechanism or the like. At this time, the seat 05 connects the rear surface 013 to the case slider 08.
It moves forward by being pushed by a case pusher 010 (see Figure 2) attached to the case.

When the sheet 05 starts moving forward, a motorized roller 011 provided at a predetermined position is applied to a predetermined position of the front flap 012 after box forming on the front surface of the sheet 05, and the roller 011 is rotated to prevent friction with the sheet. Therefore, while the front flap 012 of the sheet is sent out in the traveling direction, the front surface 012 of the sheet is prevented from falling backward along the inclined surface of the group of individual packages 01 as contents. However, according to this conventional method, since the pressing force of the sheet 05 against the rollers 011 is unstable, vertical holding against the lower surface of the front sheet is insufficient, making it impossible to form a perfect rectangular parallelepiped box.

(Problems to be Solved by the Invention) The present invention solves the problem that it is difficult to form a corrugated box into a rectangular parallelepiped, especially when the individual packages are not formed on a vertical plane, using conventional corrugated carton packaging equipment of this type. There are problems, and this is an attempt to solve them.

(Means for Solving the Problems) Therefore, the present invention provides a corrugated sheet supply device that spreads and feeds corrugated sheets horizontally, and an individual package supply device that supplies accumulated individual packages onto the corrugated sheet. a folding device that lowers the corrugated sheet and the individual packaging and simultaneously bends both ends of the corrugated cardboard sheet into an L-shape along the individual packaging; A corrugated carton packaging apparatus having a slider for moving the corrugated paperboard sheet in a direction, wherein the slider is equipped with a support device for vertically adsorbing and supporting the L-shaped rising part of the corrugated sheet, and this is a means for solving the above problem. It is something to do.

(Function) The rising portions of the front and rear surfaces of the corrugated cardboard sheet are suctioned and held vertically by suction cups to form the corrugated cardboard box into a perfect rectangular parallelepiped, regardless of the shape of the individual packaged items.

(Example) Below, an example of the present invention will be explained with reference to the drawings. Figures 1 to 4 are examples of the present invention,
Fig. 1 is a functional explanatory diagram of the entire boxing forming apparatus, Fig. 2 is a side view of the forming apparatus, and Figs. 3 and 4 are views taken along arrows A-A and B-B in Fig. 2, respectively. It is.

The configuration of this embodiment will be explained below based on these drawings. In the pre-process of the molding device, a sheet 05 which is formed into a substantially U-shape while enclosing a group of individual products 01 is placed on a conveyance rail 07 and is pushed forward by a case pusher 010 attached to a slider. The configuration is the same as the conventional one shown in FIG. In the figure, 15a and 15b are suction cups that suck and hold the front and rear flaps 012 and 013 of the seat 05, respectively, and the air cylinders 16a and 15b respectively
and 16b. The suction cup 15a that suctions the front flap 012 is an air cylinder 16a fixed on the case slider 08.
It has the function of vertically suctioning and holding the side surface of the front flap 012 of the seat 05 in conjunction with the piston rod.

Further, a suction cup 15b is provided opposite the rear flap 013 of the seat 05, and this suction cup 15b
The rear flap 013 is configured to swing around the shaft via an arm 19b in conjunction with the operation of the piston rod of the air cylinder 16b, and to vertically attract and hold the rear flap 013. Furthermore, 17 is a folding claw of the seam part 013a at the upper part of the rear flap 013, which is formed into a substantially L-shape as a whole, the tip of which is shaped like a fork, the lower end is connected to the arm 20, and the base of the arm 20 is formed into a fork shape. It is connected to the piston rod of the air cylinder 18.

Now, to explain its function, the transport rail 07
When the sheet 05 is placed on top, the front flap 012 of the sheet is suctioned by the suction cup 15a, and the rear flap 013 is suctioned by the suction cup 15b, and the air cylinders 16a,
16b to form and hold it into a complete, approximately U-shape. Next, the seam part 013a at the top of the rear flap.
The seam folding claw 17 is actuated by the air cylinder 18 to bend the seam to the inside of the box. Therefore, when the slider 08 is moved forward in the direction of arrow A by a crank mechanism (not shown), the approximately U-shaped seat 05 is moved from the case pusher 010 attached to the slider 08.
While sliding on the conveyor rail 07, the top panel with left and right flaps of the sheet, that is, the front flap 012, is bent by a guide bar (not shown), and after applying glue to each glued part, the sheet is sent to the forming device 19 for the next process. It is then crimped and molded into a perfect box shape.

(Effects of the Invention) As explained in detail above, the present invention has such a structure that holds a group of individual accessories and attaches the front and rear flaps of the approximately U-shaped seat to the bottom surface of the seat using suction cups. On the other hand, the box shape is formed by applying glue to each glued part and bending and crimping each surface while ensuring the vertical state is maintained, so the box shape follows the shape of the contents. It does not deform when stretched, and it becomes possible to form and package a box in a perfect rectangular parallelepiped. In addition, high-temperature glue is no longer scattered to unnecessary locations, which increases safety for people, improves commercial value, and reduces machine maintenance time.
