Description

[0001]
[Industrial application fields]
The present invention relates to an automatic capping device for a fitting container used in food processing and other fields.
[0002]
[Prior art]
In the above-mentioned conventional work, after the cup sent by the conveyor is temporarily stopped, the lid that is automatically taken out is pressed by the mold from above, the cup is received by the mold rising from below, The lid was tightened with a mold.
[0003]
[Problems to be solved by the invention]
However, the conventional means described above has to be replaced with a container having a different size, which requires time and labor, is inefficient, and increases the cost of the mold. there were. Further, when the lid is tightened, the cup is temporarily stopped, so that there is a problem that the processing speed is lowered.
[0004]
An object of the present invention is to solve the conventional problems as described above, and has a simple structure, reduces the equipment cost by not using a mold, and replaces the time and labor of the mold. In order to provide an automatic lid capping device for a mating container that is easy to handle and improves the workability and increases the processing speed by tightening the lid continuously without temporarily stopping the cup. [Means for solving problems]
In order to achieve the above object, the automatic lid closing device for a fitting container according to the present invention comprises a receiving belt conveyor for receiving the flanges on both sides of the cup of the fitting container supplied from below with the lid placed on the cup. And a pressing belt conveyor for pressing the flanges on both sides of the lid from above, and the lid and the cup are sandwiched from above and below by the receiving belt conveyor and the pressing belt conveyor so as to be fitted to each other.
[0005]
A round belt, a flat belt, a timing belt, or the like is used as the receiving belt conveyor and the holding belt conveyor.
[0006]
Since the width of the fitting container varies depending on the type of the container, it is preferable to configure the fitting container so that the interval at which it is pressed by operating the handle can be freely changed. And since the height of a fitting container also changes, it is preferable to comprise so that the height from a conveyance surface can be adjusted.
[0007]
[Action]
The operation will be described. First, cups filled with raw materials automatically or manually are conveyed by a conveyor. Place the lid on the cup by hand or take it out by an automatic machine. Then, with the lid placed on the cup, the cups enter the upper and lower gaps between the receiving belt conveyor and the holding belt conveyor and are sandwiched and conveyed from above and below. During this time, they are fitted together and discharged. If a conveyor such as a belt conveyor is connected, it is placed on this and sent to a packaging machine or other post-processing machine.

【Example】
The embodiment of the present invention will be described with reference to the drawings. As shown in the figure, the receiving belt conveyor 3 that receives the flanges 2 on both sides of the cup 1 from below and the flanges 5 on both sides of the lid 4 are pressed from above. A pressing belt conveyor 6. In either case, a pair of main driving rollers 8 and 9 and driven rollers 10 and 11 are arranged on both sides of the container 7 in the conveying direction, and a round belt 12 is hung on them. The main driving rollers 8 and 9 of the receiving belt conveyor 3 and the pressing belt conveyor 6 are supported by main driving shafts 13 and 14, while the driven rollers 10 and 11 are supported by driven shafts 15 and 16. Further, when the gears 17 and 18 that mesh with each other are attached to the main drive shafts 13 and 14 and are reversely rotated, the round belt 12 moves in the same direction. Then, a timing pulley 19 is attached to the main driving shaft 13 of the receiving belt conveyor 3, and a timing belt 23 is hung between the timing pulley 19 and the timing pulley 22 attached to the output shaft 21 of the motor 20 so as to be connected to each other.
[0009]
The main driving shafts 13 and 14 and the driven shafts 15 and 16 are all supported by bearings 25 attached to the side plates 24. The vertical distance between the main driving shafts 13 and 14 of the receiving belt conveyor 3 and the holding belt conveyor 6 and the vertical distance between the driven shafts 15 and 16 are not less than the height of the container 7 so that the passing container 7 does not hit. And attach.
[0010]
The round belt 12 is supported by a guide 26 from above and below so as not to bend between the conveyance of the main driving roller and the driven roller. The gap between the upper and lower round belts 12 is a gap corresponding to the height of the flanges 2 and 5 when the fitting containers 7 are fitted to each other. Note that a tension roller 27 is preferably attached to hold the tension of the round belt 12.
[0011]
As the round belt 12 of the receiving belt conveyor 3 and the pressing belt conveyor 6, a flat belt, a timing belt, or other appropriate belts can be used.
[0012]
Moreover, you may attach the conveyor belt conveyor 28 under the receiving belt conveyor 3 as needed. The conveyor belt conveyor 28 has the same configuration as the receiver belt conveyor 3, and includes a main driving roller 29 and a driven roller 30, and a timing pulley 32 attached to the main driving shaft 31 and the main driving shaft 13 of the receiving belt conveyor 3. The timing belt 34 is hung between the timing pulley 33 and the same drive is applied.
[0013]
In addition to the above, the connection method from the output shaft 21 of the motor 20 can be arbitrarily selected. Since the width of the fitting container 7 varies depending on the type of the container, it is preferable that the fitting container 7 is configured so that the interval of pressing the handle 35 can be freely changed. For this purpose, as shown in FIG. 4, fixed side plates 36 are provided on both sides of the both side plates 24, and slide bearings 37 are attached to the side plates 24, and a slide shaft 38 is inserted and supported thereby. Both ends of the slide shaft 38 are fixed to the fixed side plate 36 with bolts 39. Further, a right-hand screw nut 40 and a left-hand screw nut 41 are attached to the both side plates 24, and one end thereof is supported on the fixed side plate 36 by a bearing 43 through the width adjusting shaft 42 provided with the right and left screws. A handle 35 is attached to the end of the fixed side plate 36. And since the height of the fitting container 7 also changes, it is preferable to comprise so that the height from a conveyance surface can be adjusted.
[0014]
Depending on the type of container 7, the distance between the round belts 12 on both sides of the holding belt conveyor 6 is made narrower than the distance between the round belts 12 on both sides of the receiving belt conveyor 3 to shift the holding position of the containers 7. By configuring the lid 4, the lid 4 can be more securely tightened.
[0015]
【The invention's effect】
Since this invention is comprised as mentioned above, there exists an effect as described below.
[0016]
First of all, the construction cost is low because the structure is simple and no mold is required.
[0017]
Moreover, since it is not necessary to change a metal mold | die conventionally, workability | operativity is high.
[0018]
Furthermore, since it is not necessary to temporarily stop the cup and the lid can be continuously tightened, the processing speed is high.
[0019]
Furthermore, as in the past, the mold is simply clamped from the top and bottom with a conveyor, so that it is safe without being injured even if the hand is caught during work.
