Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for reversing and filling a product into a box, which packs the product in a top-opening box.

[0002]

[Prior Art]

 Conventionally, as a method for packing containers, for example, as shown in FIG. 8, a large automatic boxing machine generally developed for mass production is generally used, and the upright cups 32 aligned in the stacking device 10 are used. It was inserted into the box 31 assembled by the scissor making machine 18 by the insertion plate 20 attached to the tip of the air cylinder 21.

In this case, in order to reduce the material cost of the packaging box, a boxing device using a side-opening type box that can form the box with a small cardboard area is generally widely used.

[0004]

[Problems to be solved by the device]

 However, in recent years, due to the diversification of products in the food industry, the shape of containers and the specifications such as the number of boxes are frequently changed. This is due in part to the demand for small specifications, mainly at convenience stores. That is, a convenience store is generally located in a good location such as in front of a station, and since it is necessary to display many types of products in a small area, the number of display shelves and the warehouse space are generally small. Also, in order to maintain the freshness of products, many products are ordered.

Therefore, in order to meet these requirements, for example, products are shipped in a packaging box in units of five. However, many existing box-packing machines are large in size and can be easily handled. I can't do it. In addition, even if a new boxing machine corresponding to this was purchased, the specifications of the box are often changed, and in this industry, the equipment had a short life. In addition, general-purpose machines have been developed that can cope with various box shape changes, but the applicable range is actually narrow, and such devices are expensive and have the drawback of requiring a large installation area. It was

The present invention has been made in view of the above-mentioned problems of the conventional technology, and the problems to be solved by the present invention have general versatility that can easily cope with any box shape. An object is to provide a small and inexpensive simple boxing machine.

[0007]

[Means for Solving the Problems]

 The above-mentioned object is a filling device for filling an unfilled package, which is supplied in a state of covering the arrived product group with the packaging box, into the packaging box, wherein the product group is mounted on the tip of the arm. A reversing drive device that has a mounting table and reciprocates the leading end of the unfilled package and the discharge side by about 180 ° in an arc locus, and is placed on the mounting table along the arc locus of the mounting table. It is achieved by a device for reversing and filling a product into a box, which comprises a box guide guide provided on the upper and lower ridge lines of the package box.

[0009]

【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings.

1 to 7 are explanatory views of an inversion filling device according to the present invention. FIG. 1 is an overall external view, FIG. 2 is an overall configuration diagram, FIG. 3 is a side view, and FIG. 4 is a plan view. 5 to 7 show side surface operation explanatory views.

In these figures, 3 is a reversing drive device for reversing the unwrapped packing placed on the mounting table 2 by 180 ° and inserting the cup 32 into the box, which is fixed to the base 8. It has a rotary actuator 3a capable of reciprocating 180 °, an inversion arm 1 axially attached to the rotary shaft of the rotary actuator 3a, and an area capable of mounting a group of cups fixed to the tip of the inversion arm 1. It is composed of a mounting table 2. The reversing drive device 3 is arranged at a position where the mounting table 2 can reciprocate on the transport front end portion of the supply conveyor 10 and on the rear end transport path of the discharge conveyor 11. Further, the supply conveyor 10 and the discharge conveyor 11 are separated from each other, and are arranged with a step difference substantially by the height of the box. This is because the box 31 is surely turned over 180 ° and then unloaded on the discharge conveyor 11. A transfer plate 4 is provided at the front end of the supply conveyor 10 in the transfer direction in a horizontal position with respect to the transfer path. The transfer plate 4 has an annular shape with a part of the rotary actuator 3a side cut away. The mounting table 2 described above can be freely moved in and out of the annular shape. With such a configuration, the box sent from the supply conveyor 10 can be smoothly mounted on the mounting table.

Next, 5a, 5b, 6a, and 6b are box guides, which are provided in an arc shape along the turning trajectory of the mounting table 2 provided at the tip of the reversing drive device. Both ends of the guiding inner peripheral guides 5a and 5b are fixed to the transfer plate 4 and the base 8, respectively, so that the box can be stably inverted without wobbling. Then, the outer peripheral guides 6a and 6b for guiding the upper ridge of the box are fixed only at one end on the base side so that the space is slightly narrower than the size of the box to be transferred, and the other end is free and biased toward the inner guide side. It is provided to do so. Since the outer peripheral guides 6a and 6b are provided so as to be urged inward, the box and the cup can be integrally moved in the box guide without being separated during the reverse transfer of the box.

Next, the operation will be described. Here, for the sake of explanation, the case where five cup products are filled in a box will be described. Five cups 32 are made to flow in a horizontal row on the supply conveyor 10 through a known stacking and aligning device through a known stacking and aligning device to prevent the cups from falling on the conveyor, and the bottom surface is sealed from above the cups 32 by a known method. Cover the open top box.

By repeating this operation, when the sensor 16 provided at the end of the transfer plate 4 detects that the first box 31 pushed in by the supply conveyor has reached the end of the transfer plate 4, the rotary box is rotated. The actuator 3a is actuated to start reversing the reversing arm 1, and the box 31 containing the mounting table 2 and the cup 32 therein is reversed by 180 °.

During the reversing of the box, the inner guide 5 is bridged on the inner arc of the box 31 and the outer guide 6 is bridged on the outer arc of the box 31, so that the reversing trajectory of the box 31 is stable. It can be done.

Then, the box 31 in which the cup 32 is installed is naturally dropped from the open end portions of the inner peripheral guide 5 and the outer peripheral guide 6 to the discharge conveyor 11 arranged lower than the base 8 and inverted. Filling is complete and the cup is inserted into the box.

When the reversing is completed, the rotary actuator 3 a is operated to reverse the reversing arm 1 by 180 °, and the mounting table 2 is returned to the position of the transfer plate 4.

Next, the stopper 14 and the stopper 12 to be described later are opened, the box 31 covered with the next cup 32 is sent to the delivery plate 4, and the above steps are repeated.

On the other hand, the signal detected by the sensor 16 for the box 31 is sent to the stopper 12 and the stopper 14 as well as the instruction of the reversing movement.

Then, the box 12 covering the next cup 32 is sandwiched between the stopper 12a pushed out by the air cylinder 13 and the stopper 12b facing each other, and the progress on the supply conveyor 10 is stopped.

Further, the plate-shaped stopper 14 is pushed up by the air cylinder 15 from the penetrating portion provided on the supply conveyor side of the delivery plate 4 to prevent the box 31 from advancing.

However, the stopper 12 and the stopper 14 are provided only for the time from when the first box 31 reaches the position of the sensor 16 to when the mounting table 2 finishes reversing and returns to the position of the transfer plate 4 again. However, if the sensor 17 does not detect the next box 31 during this time, the stopper 12 and the stopper 14 do not operate.

The main purpose of the stopper 14 is that when the box 31 is sandwiched by the stopper 12 described above, the long side surface of the box 31 is deformed and swells, and the long side surface of the box 31 serves as the mounting table 2. This prevents problems such as damage to the box or throwing out the box when the mounting table 2 moves while protruding to the position. Therefore, the device of the present invention can be operated without the stopper 14.

Although the rotary actuator 3a is used as the reversal driving device in the present invention, a servo motor may be used.

Although the sensor 16 functions only in one direction, the sensor 16a and the sensor 16b are provided from both sides of the transfer plate, so that the box is placed on the mounting table 2 provided inside the transfer plate 4. When it reaches diagonally, one sensor does not detect it, so the rotary actuator is not activated. This is because the product may be damaged when the box 31 having the cup 32 therein is passed obliquely between the inner peripheral guide 5 and the outer peripheral guide 6 described above.

Although the outer peripheral guide 6 is supported by the handle 7 in the drawing, it can be fixed at the above-mentioned setting position of the outer peripheral guide. You can connect them.

Further, although not shown in the drawing, the inner peripheral guide 5 and the outer peripheral guide 6 may be formed by curving the surfaces, or rollers may be arranged on the inner surface of both or one of the guides. If so, a smoother reversing motion can be achieved, so that the speed can be increased. Further, in the maximum size of the box on which the mounting table is mounted, various box specifications can be used if only the outer peripheral guide is replaced according to the size of the box. This outer guide is fixed in only one place, so replacement is easy.

[0028]

[Effect of the device]

 As described above in detail, according to the present invention, since the container is turned over together with the box, it is possible to provide a compact and inexpensive simple boxing machine having a simple structure that is hard to break down. Further, since it can be applied to various products only by changing the box guide guide, it is possible to provide a highly versatile box packing machine.
