Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a box packing device for storing containers in a plurality of rows in a box.

"Prior Art" A conventional packing device has a mechanism in which a gripping head grips multiple rows of containers supplied onto a table, and then the table is retracted and the gripping head is lowered to store the gripped containers in a box below (Japanese Utility Model Publication No. 48-24473).

In this type of boxing equipment, there are cases where a wooden box and a plastic box are used as the boxes, and cases where 30 containers are stored at once in three boxes of 10 containers, and cases where 30 containers are stored at once in three boxes of 10 containers, and in cases where a box of 6 containers is stored at once. In the case of storing in five boxes, etc., it is necessary to match the position of each container with the container storage position of the box according to those conditions, and then store the containers in the box.

``Problem that the invention aims to solve'' For this reason, conventionally the position of the guide member that guides the containers in each row was adjusted according to each condition, but the amount of adjustment in the lateral direction with respect to the conveyance direction of the containers was particularly large. Sometimes, the position of each guide member must be adjusted over a relatively long distance along the container conveyance direction, which requires a lot of time and effort.

Particularly where containers need to be spaced apart in relation to the box below, two guide members are required to guide each container between the mutually spaced containers; In order to arrange the containers to be adjacent to each other, it is necessary to overlap the two guide members vertically. Therefore, especially when multiple types of boxes are used, the number of two guide members superimposed one on top of the other increases, making the above-mentioned change work even more complicated.

"Means for Solving the Problem" In view of the above circumstances, the present invention provides a conveyor that conveys containers to the guide members and grippers disposed on the table in a plurality of rows along a plurality of first guide members. a table that moves between a support position that supports the bottom of the container supplied from the conveyor and a retreat position that allows the container to descend; and a table that is connected to the tip of each first guide member above the table in the support position. a plurality of second guide members disposed in such a manner;
In a boxing device comprising a plurality of gripping heads that grip containers introduced onto the table and lower each container and store them in a box when the table retreats, the plurality of gripping heads are synchronized with the operation of the boxing device. A moving mechanism is provided for moving the second guide member and the gripping head between a reference position and a storage position, and in the reference position, the second guide member is moved between the first and second guide members.
The gripping head is located at a position continuous with the tip of the guide member and guides the container supplied from the conveyor, and the gripping head is located at a position where it can grip the container guided by the second guide member, and In the storage position, the gripping head is in a position where the gripped container can be stored in the box below, and the second guide member prevents the container from moving as the gripping head moves from the reference position to the storage position. It is designed to be located in a position where it will not interfere.

"Function" According to the above configuration, when the type of box is replaced, it is only necessary to change the storage positions of the respective gripping heads and the second guide member, that is, the movement stop positions from the reference position, and the first Since no modification work is required for the guide member, the modification work can be made much easier than conventional work.

"Example" The present invention will be explained below with reference to the illustrated example.
In FIG. 1, 1 is a conveyor that conveys the container B to the left, 2 is a plurality of first guide members (see FIG. 2) arranged on the upper part of this conveyor 1, and the container is connected to each first guide member. 2 are continuously transported by the conveyor 1 in a plurality of rows. A table 4 is disposed in front of the conveyor 1 via a fixed span plate 3.
is movable diagonally along the guide 5 by a drive source (not shown).

When the table 4 is in the support position adjacent to the spanning plate 3, the surface of the table 4 and the surface of the spanning plate 3 become substantially the same surface, and the surface of the table 4 is substantially the same as that of the spanning plate 3. The bottom surface of the container B to be supplied can be supported. Further, when the table 4 is in the retreated position diagonally downward from the spanning plate 3, the container B can be allowed to fall as will be described later.

As shown in FIGS. 1 and 2, the same number of second guide members 6 as the first guide members 2 are disposed on the table 4 located at the support position.
Each second guide member 6 is attached to a pair of parallel support rods 8 horizontally disposed on the machine frame 7, as shown in FIG.
and 6 are disposed on the same straight line, and the containers from the conveyor 1 are guided by the second guide member 6 so that they can be smoothly introduced onto the table 4.

A stopper member 10 is provided on the table 4 at an intermediate position between each of the second guide members 6 to abut against the container and stop its advancement. This stopper member 10 is installed so that two containers can be positioned on the table 4 in the supply direction of the containers B, and above the third container B on the spanning board 3 following the two containers. is provided with a stopper 11 that is raised and lowered by a cylinder device (not shown), and this stopper 1
1 allows the third container to be pressed against the spanning plate 3 and stopped.

A gripping head 12 for gripping each container is provided directly above each container supplied on the table 4, and each gripping head 12 can be raised and lowered simultaneously by a cylinder device (not shown). Further, below the table 4, a guide member 13 for guiding the descent of each container is removably attached to the machine frame 7, and further below each guide member 13 is provided a conveyor 14 for conveying the boxes. This conveyor 14 intermittently conveys boxes (not shown) in a direction perpendicular to the plane of the paper in FIG. The lower ends of each guide member 13 can be inserted into the plate.

The above configuration is basically the same as that of a conventionally known boxing device, and the containers B, which are continuously conveyed by the conveyor 1, are introduced onto the table 4 located at the support position, and are placed on the stopper member 10. It stops when it comes into contact with it. When it comes into contact with the first container gas stopper member 10 and stops, the stopper 11 descends and the third container gas stopper member 10 is stopped.
Stop the main container. At the same time, when the container gripping head 12 descends and grips each container, the table 4 moves diagonally downward from the supporting position to the retracted position, releasing the support for the bottom of the container B.

By this time, the empty boxes have been introduced onto the conveyor 14 to a position directly below the guide members 13 and have been raised, and the lower ends of each guide member 13 are positioned within the partition plates provided inside the boxes. When the gripping head 12 that grips the container is lowered in this state, the container is dropped into the guide member 13 and descends within the guide member 13 while increasing the distance between the lower ends of the member 13. Since the lower end of the member is located within the partition plate provided in the box, the container B is smoothly accommodated therein without colliding with the partition plate.

When the container B is stored in the box, the gripping head 12 releases its grip on the container and rises, and when the lower end of the gripping head 12 passes over the table 4, the table 4 is advanced to the supporting position. Then, when the gripping head 12 reaches the rising end, the stopper 11 rises to release the stop of the container B, so that a new container B is introduced onto the table 4. On the other hand, the box containing the container B is lowered by the conveyor 14 and carried outside,
A new empty box is introduced to a position directly below the guide member 13 and raised, and the same operation as described above is repeated thereafter.

However, in the present invention, a moving mechanism is provided for moving the second guide member 6 and the gripping head 12 between the reference position shown in FIG. It is set up.

Since the movement mechanism of the second guide member 6 and the movement mechanism of the gripping head 12 have substantially the same configuration, only the movement mechanism 20 of the second guide member 6 will be described, as shown in FIG. This moving mechanism 20 includes a pair of left-right symmetrical moving mechanisms 20A,
20B, each moving mechanism 20A, 2
0B are adapted to be operated symmetrically by cylinder devices 21A and 21B, respectively. Each of the moving mechanisms 20A and 20B has the same structure except that they are symmetrical, so one of the moving mechanisms 20A and 20B is
The specific configuration of only A will be explained with reference to FIG.

In FIG. 3, the moving mechanism 20A is equipped with a link plate 22 that is reciprocated in parallel with the support rod 8 in conjunction with the cylinder device 12A, and engagement holes 23 are bored at predetermined positions in the link plate 22. The pins 24 attached to each of the second guide members 6 are passed through the inner portions. The second guide members 6 are provided so as to be able to slide on the support rod 8, except for the guide member 6A on the center side which serves as a reference, and the reference guide member 6A is fixed to the support rod 8. A second link plate 25 is provided above the link plate 22, and a reference engagement hole 26A formed at one end of the link plate 25 is engaged with a pin 24A provided in the reference guide member 6A. An engagement hole 26 is formed at a required position to fix the link plate 25.
The pins 24 of each of the second guide members 6 are passed through.

Each engagement hole 26 formed in the link plate 25 on the fixed side
The left end portion of is arranged so that when the pin 24 of each second guide member 6 is located at that position, the second guide member 6 is located at a reference position in which the second guide member 6 is located in line with the first guide member 2, respectively. It is set up in Further, the right end of each engagement hole 26 is located at a storage position where, when each pin 24 is located at that position, the container can be smoothly stored in a predetermined box by guiding the fall of the container in that state. It is set to do so.

Therefore, the length of each engagement hole 26 in the support rod 8 direction is from the left end, which is the reference, to each second
The guide member 6 has a length that matches the amount of rightward movement of the guide member 6 and does not need to be moved.
The engagement hole 26A for A is large enough to simply engage the pin 24A.

On the other hand, the engagement hole 23 of the other link plate 22
The engagement hole 23A that engages with the fixed pin 24A has a length that corresponds to the amount of movement of the second guide member 6 that is moved the most, that is, the second guide member 6 that is moved the most. In the illustrated embodiment, the right end guide member is fixed to the link plate 22. The cylinder device 21A reciprocates the link plate 22 within the range of the engagement hole 23A, and therefore the second guide member 6 at the right end is reciprocated between the reference position and the maximum displacement position, that is, the accommodation position. It becomes like this.

As for the second guide member 6 at the right end, engagement with the upper link plate 25 is omitted. Second guide member 6 displaced by another intermediate amount
Each of the pins 24 engages with the engagement holes 26 and 23 at the same time, and the length of each engagement hole 23 is equal to the length of both engagement holes 26 and 23.
The total length measured at the center of the pin 24 at 6 and 23 is set to match the similar length at the engagement hole 23A.

Therefore, when the container B is introduced onto the table 4, the cylinder device 21A positions each second guide member 6 at the reference position of each left end of the engagement hole 26 with the link plate 22 as the left-hand end. In this state, each second guide member 6 is in a straight line with the first guide member 2, and smoothly guides the introduction of the container B onto the table 4.

The gripping head 12 grips the container B and holds it on the table 4.
When the container B is moved backward, the gripping head 12 is moved by a moving mechanism (not shown) to position the container B at a housing position that matches the shape of the box below. At the same time, the cylinder device 21A moves the link plate 22 to the right-hand end accommodation position, and moves each second guide member 6 to the accommodation position shown in FIG. 3, that is, from the reference position of the gripping head 12 to the accommodation position. The container B is moved to a position that does not obstruct the movement of the container B as the container B moves. At this time, it goes without saying that the other moving mechanism 20B operates in the same manner to move all the second guide members 6 to the accommodation position.

Thereafter, when the gripping head 12 descends to house the container B in the box and releases its grip, each gripping head 12 and the second guide member 6 return to their original reference positions as the gripping head 12 rises. The same operation is repeated again.

When changing the type of box, all that is required is to replace the link plates 22 and 25 with link plates manufactured to match the storage position of the new box, which greatly simplifies the change process compared to the conventional method. can be converted into

Note that the container guide member 13 is replaced with one that matches the shape of the box when the shape etc. of the box is changed in advance, but the container guide member 13 may also be provided with a moving mechanism similar to that described above. , or can be omitted. Furthermore, the moving mechanism is not limited to that of the above-mentioned embodiments, but it is also possible to group together objects with the same amount of displacement and to operate each one by a cylinder device, or by using a drive source of a box packing device. It is also possible to operate in synchronization with this using a link mechanism or the like that is operated accordingly.

"Effect of the invention" As described above, according to the invention, when the type of box is replaced, the housing positions of each of the gripping heads and the second guide member, that is, the movement stop positions from the reference position are changed. Moreover, since there is no need to change the first guide member, the effect is that the change work can be made much easier than the conventional work.
