TECHNICAL FIELD OF THE INVENTION
The present invention provides a crankshaft that is rotatable around an axis, a crankpin provided on the crankshaft, a container mounting plate on which a container can be mounted is attached to the crankpin, and the container mounting plate is The container is provided with a support portion that supports the main shaft so as to be horizontally rotatable and movable around a support axis different from the center, and a container shaking device provided with a rotation drive mechanism that drives the crankshaft to rotate around the axis.
More specifically, for example, a container containing a liquid is placed on a container placing plate and rotated about an axis, thereby horizontally rotating the container and stirring the liquid contained in the container. The present invention relates to a container shaking device used in such a case.
[0002]
[Prior art]
Conventionally, such a container shaking device is provided with a crankpin having a different phase around an axis from a crankpin to which a container mounting plate is attached, providing a balance weight to the crankpin, and The balance weight and a one-sided shaking unit are provided as a pair, and the container mounting plate and the balance weight are configured to rotate horizontally while maintaining a balance, and the container is mounted on the container mounting plate. When the crankshaft is rotated in this state, the container is horizontally rotated and shaken. When a large number of containers are shaken at one time, a structure in which the one-side shaking units are connected in multiple stages and the required number of stages are provided is used.
[0003]
[Problems to be solved by the invention]
However, in the above-described conventional configuration, since one balance weight is provided per one surface of the container mounting plate, when the number of the container mounting plates is increased, the weight of the balance weight is increased by the amount of the load applied to the support member. And there is a disadvantage that the weight of the apparatus increases.
In addition, in order to use the balance weight having a predetermined weight in a fixed state, when trying to shake a container in a configuration in which a large number of containers are placed on one surface of the container mounting plate, the container mounting plate is used. And the balance with the balance weight changes depending on the number of containers to be placed, and in some cases, the rotational balance may be lost, and in particular, the stability of the entire apparatus may be reduced when the container placing plates are provided in multiple stages. There was a risk of causing it.
[0004]
Therefore, the present inventors set the phase around the axis of the plurality of crankpins so as to balance the container mounting plates so that the plurality of container mounting plates serve as balance weights to each other. We have proposed a liquid mixing device in a container that can be used. According to this, a configuration capable of coping with the former problem can be obtained in that the balance weight can be reduced, but for the latter problem, individual container mounting plates can be used. The latter problem can be solved by balancing the quantity and weight of containers placed on each container mounting plate for a set of container mounting plates that are not balanced by each other but by each other. Depending on the number of containers to be placed, the operation of balancing the weights may be extremely complicated, and there is room for further improvement.
[0005]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a container shaking device which can solve the above-mentioned conventional drawbacks, can reduce the weight of the device even if the number of container mounting plates is increased, and can easily balance the rotation.
[0006]
[Means for Solving the Problems]
The features of the present invention for achieving the above object are as follows:
A crank shaft that is rotatable around an axis is provided, a crank pin is provided on the crank shaft, a container mounting plate on which a container can be mounted is attached to the crank pin, and the container mounting plate is different from the axis. In a container shaking device provided with a support portion for supporting a horizontally rotatable movable around a support axis, and a rotation drive mechanism for driving the crankshaft to rotate about the axis,
A pair of crankpins is provided at a position where the phase is shifted by 180 degrees around the crankshaft in a plan view, and at adjacent positions having different heights in a side view to constitute a two-plane shaking unit, A plurality of two-sided shaking units are formed side by side on one crankshaft.
Or
At a position where the phase is shifted by 120 degrees around the crankshaft in a plan view, and at adjacent positions having different heights in a side view, a set of crankpins is provided to constitute a three-plane shaking unit,
At least one pair of the two-plane shaking unit and at least one set of the three-plane shaking unit are formed side by side on one crankshaft,
It is preferable that, in the two-plane shaking units, a position where the crankpin is provided on the crankshaft is provided with a phase shifted around the crankshaft.
[0007]
(Function and effect)
In other words, a rotatable crankshaft is provided around the axis, a crankpin is provided on the crankshaft, a container mounting plate on which a container can be mounted is attached to the crankpin, and the container mounting plate is defined as an axis. Is provided with a support portion for supporting a horizontally rotatable movement around a different support axis, and if a rotation drive mechanism for driving the crankshaft to rotate about the axis is provided, rotating the crankshaft provides the container. The mounting plate is horizontally rotated around the support axis while being supported by the support portion with the rotation of the crankshaft. Therefore, the container is shaken by horizontal rotation, and can be configured to be able to shake and stir the liquid and the like contained therein. At this time, the phase is shifted by 180 degrees around the crank axis in plan view, and If a pair of crankpins are provided at adjacent positions having different heights visually and a two-sided shaking unit is configured, the two-sided container mounting plates serve as balance weights for each other, and The container mounted on the container mounting plate can be shaken, and when a plurality of containers are dispersedly arranged, the arrangement of the containers can be easily changed to achieve a balance. Therefore, when a plurality of the two-plane shaking units are formed side by side on a single crankshaft, there is no need to particularly balance between the two-plane shaking units, and the container mounted on the container mounting plate is not required. If the container dispersing operation is performed only in the two-sided shaking unit part whose number is less than the predetermined number, the container as a whole apparatus can be arranged without the troublesome work of changing the container arrangement for all the container mounting plates. Arrangement can be balanced.
[0008]
In addition, according to such a configuration, it seems that it is possible to cope with only the even-numbered-stage container shaker, but the odd-numbered-stage container shaker (5 stages, 7 stages,...). In some cases, a set of crankpins is provided at a position where the phase is shifted by 120 degrees around the crank axis in a plan view and at adjacent positions having different heights in a side view, and a three-plane shaking unit is provided. If the components are configured and used in combination with the two-sided shaking unit, the arrangement of the containers can be relatively easily balanced.
This is because if containers are distributed and arranged in the following process, the number of containers that must be changed is almost always less than one container mounting plate, even if a detailed plan was not made at the initial stage. It is because it is adjusted to.
[0009]
First, when a large number of containers are to be placed on the container mounting plate of a plurality of stages, firstly, it is necessary to roughly calculate how many surfaces of the container mounting plate correspond to the total number of the containers, and then prepare three surfaces. The number of containers that satisfy the shaking unit is preferentially placed on the container mounting plate of the three-sided shaking unit (step 1). Next, when the dispensing arrangement of the containers progresses and it is found that the remaining containers are less than two surfaces (Condition 1) or that the three-side shaking unit has disappeared (Condition 2), The container starts to be placed on the two-sided shaking unit (step 2). Further, in the step after the condition 2, the distribution of the containers is further advanced, and if it is determined that the remaining containers are less than two surfaces, the process proceeds to the next step 3. That is, in step 3, the remaining containers are equally distributed on the two-sided container mounting plate to the two-sided shaking unit. Thus, the shaking operation can be performed such that the pair of container mounting plates constituting each of the shaking unit portions or one of the pair constitutes a balance weight. In addition, during distribution of the containers to the three-sided shaking unit, it was found that the number of remaining containers was insufficient to satisfy the three-sided shaking unit (condition 3), or after the step 1, In a case where the number of remaining containers exceeds two surfaces of the container mounting plate and is less than three surfaces (condition 4), the containers are placed on the three container mounting plates in the three-surface shaking unit. (Step 4). Also in this case, the shaking operation can be performed so as to be a balance weight between the pair of container mounting plates constituting each of the shaking unit sections or between the pair constituting the one or a pair. That is, in both the case of step 3 and the case of step 4, the containers are usually placed on the container placing plate sequentially and filled, and finally the total number of containers is determined in detail, and the balance is adjusted. In the case of re-distributing the containers so as to take them, it is only necessary to move the containers not more than one surface of the container mounting plate.
[0010]
In the case where a plurality of the two-plane shaking units are provided, if the position at which the crankpin is provided on the crankshaft is provided with a phase shift around the crankshaft between the two-shape shaking units. Also, the load around the crankshaft can be distributed between the two-plane shaking units, thereby preventing a biased stress from being applied to the crankshaft, thereby enabling a smooth shaking operation.
[0011]
Therefore, it is possible to eliminate the need for a balance weight, and when the number of container mounting plates is increased, the rotation balance when rotating the container mounting plate can be balanced for each container mounting plate. Even if the number of mounting plates is increased, the weight of the apparatus can be reduced, and the rotational balance can be ensured over all the container mounting plates.
[0012]
