Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a centering conveyor that transports a placed article and aligns it in the center.

[0002]

[Prior art]

 FIG. 6 shows a schematic configuration for a typical prior art centering conveyor. When the sponge cake 2 is conveyed on the conveyor belt 1 and the weight is checked by the weight checker 3, the sponge cake 2 needs to be supplied to a certain position of the weight checker 3, for example, a central position. If it deviates from the central position, the error in the weighing result will increase, and if it deviates greatly, weighing will become impossible.

The sponge cake 2 conveyed on the conveyor belt 1 is not necessarily in an aligned state. A centering conveyor 4 is provided to supply the sponge cake 2 from the central position of the weight checker 3. On the centering conveyor 4, there is provided a "C" -shaped guide 5 in which the interval is increased on the upstream side and decreased on the downstream side. The sponge cake 2 arranged in the center by the guide 5 on the centering conveyor 4 is weighed by the weight checker 3 and further conveyed by the conveyor belt 6.

As an article centering device, there is another prior art disclosed in Japanese Patent Application Laid-Open No. 62-222920. In this prior art, the article guide is provided parallel to the conveying direction of the roller conveyor, and the axis of the roller is inclined from the direction perpendicular to the article guide. As a result, the conveyed article is conveyed on the roller conveyor along the article guide while moving in the article guide direction. By adjusting the position of the article guide, the position where the articles are aligned can be adjusted.

[0005]

[Problems to be solved by the device]

 According to the above-described prior art, when a soft product such as the sponge cake 2 is going to be centered, the shape of the sponge cake 2 is easily deformed by the force received from the guide 5. Further, since the sponge cake 2 contains a large amount of oil and fat, sponge debris containing oil and fat adheres to the conveyor conveyor belt and roller conveyor for transportation and is sticky, and receives force from the guide 5. However, the sponge cake 2 cannot be moved smoothly. Therefore, the sponge cake 2 is likely to be further deformed or scratched. Further, it is not preferable in terms of hygiene that dirt is attached to the guide 5.

As described above, in the product finishing line, the centering of the product, that is, the position regulation of the product work is required, which is important. Therefore, an improved centering device is strongly desired.

An object of the present invention is to provide a centering conveyor that can be easily aligned in the center without being guided by a guide or the like.

[Means for Solving the Problems]

 According to the present invention, a plurality of conveyor rollers are arranged in two rows, the conveyor rollers in each row are inclined so as to be lowered toward the center, and are arranged in a V shape in a horizontal plane so that the center is on the upstream side. The centering conveyor is characterized by the fact that

[0009]

[Action]

 According to the present invention, the conveyor rollers in each of the two rows are inclined so as to become lower toward the center. For this reason, the gravity conveyed toward the center acts on the articles conveyed on the conveyor rollers. Furthermore, since the conveyor rollers are arranged in a V shape in the horizontal plane so that the center is on the upstream side, even if the conveyor rollers are displaced from the center at the entrance while being conveyed from the entrance to the exit, they will be at the exit The position is corrected to. Since the centering is possible while being conveyed by the conveyor rollers, there is no need for guides to regulate the position, and even soft articles can be conveyed hygienically without being deformed or damaged. You can

【Example】

 FIG. 1 shows a planar structure of a centering conveyor device according to an embodiment of the present invention, and FIG. 2 shows a side cross section taken along the section line II-II of FIG. The centering conveyor 10 is provided between the upstream side conveyor belt 11 and the downstream side conveyor belt 12, and conveys the articles conveyed by the upstream side conveyor belt 11 in the direction indicated by the arrow 13 to the downstream side conveyor belt 12. Align in the center.

The centering conveyor 10 includes a motor 15 that applies a rotational driving force, bearing boxes 17 and 18 to which a rotational driving force is applied via a connecting shaft 16, a frame 19 that mechanically holds these, and a roller 20. 29 to 30 and 39 are included. The rollers 20 to 29 and 30 to 39 are arranged in two rows. The rollers 20 to 29 for one row are supported by the bearing box 17 on the motor 15 side. The other row of rollers 30 to 39 are supported by the other bearing box 18. As shown in FIG. 1, the rollers 20 to 29 and the rollers 30 to 39 are arranged in a V shape in the horizontal plane so that the center is on the upstream side.

As shown in FIG. 2, the rollers 29 and 39 in each row are attached so as to be inclined so as to be lowered toward the center. The connecting shaft 16 for transmitting the rotational driving force to the bearing boxes 17 and 18 is pivotally supported upward by the columns 41 and 42. One bearing box 17 is attached to the frame 19 in a tilted state via the columns 43 and 44. The other bearing box 18 is attached to the frame 19 in an inclined state by the columns 45 and 46. The rotational driving force of the motor 15 is transmitted by a chain 49 that is stretched between a sprocket 47 fixed to the shaft of the motor and a sprocket 48 fixed to the connecting shaft 16. From the connecting shaft 16 to one bearing box 17, a rotational driving force is generated by a belt 53 that is stretched between a pulley 51 fixed to the connecting shaft 16 and a pulley 52 fixed to the shaft on the bearing box 17 side. Transmitted. Due to the belt 56 that is stretched between the pulley 54 fixed to the other side of the connecting shaft 16 and the pulley 55 fixed to the shaft protruding from the other bearing box 18, the rotational driving force is also applied to the other bearing box 18. Transmitted. Since the shafts of the bearing boxes 17 and 18 are inclined in the horizontal plane and the vertical plane, the rotational driving force is transmitted by the pulleys 51, 54; 52, 55 and the belts 53, 56.

FIG. 3 shows a cross section taken along section line III-III in FIG. The center shaft 61 of one roller 38 is extended to the bearing box 18 side and is axially supported. Pulleys 62 and 63 are fixed to the shaft 61. Belts 64 and 65 are stretched between the pulleys of the adjacent shafts to transmit the rotational driving force.

As described above, the rotationally driven rollers 20 to 29 and 30 to 39 are divided into two and are provided with a relative three-dimensional inclination. In addition, the rotation axis is inclined so that the central portion is upstream in the plan view. Due to this plane inclination, it is possible to correct the deviation from the center and transfer it to the center during the transportation from the entrance to the exit. In addition, as the three-dimensional inclination, the inclination is set so that the central portion is lower than the horizontal, so that the centering effect of the shoot function to the center by gravity is improved. Further, in order to smoothly convey a Western confectionery containing a large amount of fats and oils, the rollers 20 to 29 and 30 to 39 can be made more slippery by coating them with urethane resin.

4 and 5 show the construction of a sponge cake production line using the centering conveyor 10 shown in FIG. FIG. 4 shows the configuration of the entire line, and FIG. 5 shows a part thereof. From the oven 71, the sponge cake 73 baked in the mold 72 is carried out. The sponge cake 73 is taken out of the mold 72 by the take-out device 74. The taken-out sponge cake 73 is transferred to the cream filling device 75, filled with the cream, and then taken out onto the conveyor belt 76. From the oven 71 to the conveyor belt 76, for example, five sponge cakes 73 are processed in parallel. It is taken out in a row from the conveyor belt 76, aligned by the centering conveyor 10 via the curve conveyor 77, and taken out from the conveyor belt 78 to the weight checker 79. The weight checker 79 cannot accurately measure the weight unless the sponge cake 73 is aligned at a certain position. On the other hand, when the sponge cake 73 is taken out from the cream filling device 75 onto the conveyor belt 76, the position of the sponge cake 73 is displaced. For this reason, it is necessary to provide the centering conveyor 10 and align the sponge cakes 73 that are misaligned.

The reason why the position shifts when the sponge cake 73 is transferred from the cream filling device 75 onto the conveyor belt 76 will be described with reference to FIG. In the cream filling device 75, the filling machine 83 is arranged above the belt stretched between the pulleys 81 and 82. The sponge cake 73 moves from the take-out device 74 onto the belt, and after the cream 84 is filled by the filling machine 83, the sponge cake 73 moves onto the conveyor belt 76 by the air injection from the air nozzle 85. When the cream 84 is removed from the cream filling device 75, it is necessary to perform air injection from the bottom surface since the cream 84 is already filled. For this reason, the position of the transfer on the conveyor belt 76 varies.

In the above embodiment, the centering conveyor 10 is used to accurately measure the weight by the weight checker 79, but foreign matter such as metal is inspected, further decorated, and packed. Of course, the device may be positioned and supplied. Further, it goes without saying that the articles to be conveyed may be not only sponge cakes but also other foods. Since it is not necessary to contact a guide, it can be handled hygienically. In addition, the articles are not limited to food items and can be aligned without scratches or deformation because they do not use guides.

In the embodiment shown in FIGS. 1 to 3, the rotational driving force from the motor 15 is transmitted to each of the rollers 20 to 29 and 30 to 39 via the connecting shaft 16, but each of the bearings Of course, it may be provided for each of the boxes 17 and 18, or some of the rollers 20 to 29 and 30 to 39 may be directly driven by the motor. Needless to say, a gear or the like may be used as the mechanism for transmitting the rotational force. According to this embodiment, the rotational force can be efficiently transmitted even if the distance between the bearing housings 17 and 18 is changed or the inclination of each of the rollers 20 to 29 and 30 to 39 is changed.

[0019]

[Effect of device]

 As described above, according to the present invention, the conveyor rollers arranged in two rows can center the articles while conveying the articles from the inlet to the outlet. Therefore, even an article such as a sponge cake that is soft and contains oil and fat can be transported while being centered hygienically without being scratched or deformed.
