[Industrial applications]

 TECHNICAL FIELD The present invention relates to a device for stacking a plurality of appropriately loaded or empty containers up to a suitable height.

[0002]

[Prior art and problems]

 When performing mechanical processing on bottles and other arbitrary items, it is widely practiced to put them in a container and to collectively process them on the line instead of processing them individually. This is because it is more efficient to collectively process the items in the container than to individually machine the individual items. For example, in the case of artificial cultivation of mushrooms, the culture medium is packed in a culture bottle and sterilized in a sterilization kettle, then seeded with inoculum to spread hyphae, mushrooms are grown and then harvested, and the used culture medium is scraped out. The procedure is carried out again by packing new culture medium, but each work is not carried out in individual culture bottles as a unit, but is usually carried out in a processing unit which is a container capable of holding 16 culture bottles. This container is a box-shaped container with the top open, and has a flange formed around the upper edge for easy transportation.

The processing of each work is performed in a unit of one container, but during each processing work, it moves in a stacked state in a plurality of stages and is transferred to a target place. In order to disassemble each container and process it, and to send it to the next process, it is necessary to re-load the containers disassembled in each stage into multiple stages.

As a device for stacking conventionally sent containers in multiple stages, each container sent from some processing device is lifted to a height higher than the top stage and horizontally sent to a stacking place, and from there By lowering it, the container with the specified number of stacks will be stacked, and the container that has been sent will be forwarded to the place where the lowermost container will be horizontally stacked, and the next container will be lifted to the second level. The work is repeated horizontally to the top of the bottom container, and this operation is repeated for the desired number of steps. After stacking the specified number of steps in this way, the whole is sent further forward and the same operation is repeated. The problem with the former is that it requires a large amount of space, and the drawback with the latter is that the control of the container lifting mechanism is complicated and adjustment is extremely difficult.

[Means for solving problems]

 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a container stacking device that saves space, has a simple configuration, and is extremely easy to control. The main points are: rails standing on both sides of the conveyor, an elevating member that moves up and down guided by the rails, and an inwardly projecting member from the elevating member that is almost horizontal when opened. It is composed of an engaging member that is elastically held on and rotatable only upward.When the engaging member is horizontal, the tip of the engaging member reaches the position where it engages with the flange of the container. This engagement member reciprocates from a position below the flange of the lowermost container to a position at which the lowermost container reaches a height at which another container can be inserted downward. Stacking It is a device.

The pretreatment process to which the device of the present invention is applied may be any process, and any process may be used as long as the container is sent out step by step after processing. The container can be empty or empty. The stored items may be solids, liquids, powders, etc., and may also be bottle-like items. This container has a flange protruding laterally. This flange normally functions as a handle, but it is usually formed around the mouth of the container. However, it may be anything other than that, as long as it is provided at the upper edge or in the middle of both sides in the feeding direction of the container.

[0007] A conveyor is provided in the main body of the apparatus. The conveyor positions each container that has been sent to a predetermined position, and when the predetermined stacking is completed, sends the entire unit to the outside. .. Rails are erected on both sides of this device, and an elevating member is fitted on the rails so as to be able to move up and down, and engaging members are symmetrically projected toward the inside, that is, toward the container. .. The elevating member moves on the rail by a reciprocating motion engine such as a crank, and the engaging member connected to the elevating member reciprocates up and down correspondingly. This engaging member may be one that uses one piece as a supporting member and another piece that is elastically held like a hinge, or may consist of only a rotating piece that is directly attached to the lifting member. In any of these cases, the engaging member is elastically held substantially horizontally when opened, and can be rotated only by an external force upward.

Further, when the engaging member is horizontal in the opened state, the tip of the engaging member is long enough to reach the position where it engages with the flange of the container disposed inside, and The engaging member reciprocates from a position below the flange of the lowermost container to a position where the container is lifted to a height below which the lowermost container can be inserted. In this specification, the lowermost conveyor is a container placed on the conveyor, and the container stacked thereon is the second container. The engaging member is located below the flange of the lowermost container, so that it is horizontal and engages the flange of the container when rising. When a flange is formed on the upper edge of the container, the engaging member is lifted to a position higher than the fixed position of the flange when the second-stage container is placed on the bottom-most container. Have to be done. In any case, the engaging member reciprocates from a position below the flange of the lowermost container to a position at which the lowermost container reaches a height below which another container can be inserted.

[0009]

Since the present invention is configured as described above, when the first container is sent to the main body of the apparatus, the engaging member descends so as to engage with it. The engaging member holds the horizontal state elastically when it is free, but since it can rotate upward, even if the flange of the container that was sent downward is positioned, The descent is unobtrusive, rotating upwards to clear that part. When it goes below the position of the flange, it becomes free, so the engaging member returns to the horizontal state again, and when it rises in this state, the engaging member and the flange of the container engage, and the engaging members on both sides move the container. The conveyor will be lifted up in a held state.

The engaging member lifts the container to a position slightly higher than the second-stage position (a predetermined position stacked on the lowermost container) so that the lowermost container can be inserted. It is desirable to pause, and during that time, the next container will be sent under the container that was lifted, and it will become the lowest container. After confirming this, the engaging member starts to descend. As a result, the second-stage container is placed on the lowermost container, but the engaging member is further lowered. At this time, the engaging member separates from the flange of the second-stage container, but the horizontal state is maintained. The flange of the bottom container is on the path of passage of the tip of the engaging member, but since the engaging member can rotate upward, it is forcibly rotated upward when it hits the flange, Clear the flange part of the container. By repeating such operations, stacking of a desired number of stages, for example, 4 to 5 stages is completed. When it is completed, the conveyor is driven to send it out in a multi-tiered state.

[0013]

【effect】

 As described above, in the present invention, the stacking of containers is carried out by raising the container on the conveyor by a height corresponding to almost one stage, and the next container is sent to the space created thereby without changing the level. Since the stacking is performed by repeating the process as many times as necessary, the space is minimized, and the engaging member is located at a position slightly lower than the fixed position of the flange of the second stage container from the position below the flange of the lowermost container. The control system is simple because it only reciprocates up to, and as a result of adopting the above-mentioned method, it is sufficient to provide an engaging member with a simple structure, thus reducing the manufacturing cost. I was able to do it.
