Description

[Detailed description of the invention] [Industrial application field] This invention is used to classify grades, classes, etc. (sorting classes) using a sorting machine in a facility for sorting fruits and vegetables.
This relates to a boxing stand for manually packing objects to be sorted, such as fruits and side dishes, which have been separately sorted and discharged onto a storage section.

[Conventional technology]

Conventionally, storage units for accommodating materials to be sorted and discharged according to classification such as grade and class by a sorting machine have been divided into a pull-out belt conveyor type shown in Fig. 1, a turntable type shown in Fig. 2, and a third storage unit. The so-called receiving box type shown in the figure is mainly used, and the simple workbench shown in the above figures is widely used and known as a boxing stand for manually packing the items on the storage section. be.

In addition, in the case of the drawer belt conveyor type shown in Fig. 1, various proposals have been made as a boxing stand.
Jitsukō No. 55-46668, Jitsukō No. 55-47769, Jitsukōaki
No. 56-20429, Jitko No. 56-20430, Jitko No. 56-
Those shown in various publications such as No. 33958 are publicly known.

The above-mentioned conventional known method attempts to pack boxes into boxes of a certain size, and when the boxes are placed on a table and the items to be sorted are boxed, the table is not used. The height is constant and unchanging, and the transfer of the boxed products to the transport conveyor that transports the boxed products (boxed products) is the roller that receives the boxed products of approximately constant weight. This was done either by rotation (as in the above-mentioned publications) or by having a boxer pick up the boxed product and place it on a conveyor (FIGS. 1 to 3).

In addition, the conventional and well-known boxing stand described above is not provided with a printing device that automatically prints classification marks such as grade and class on the packaging container, and in particular, the markings shown in FIGS. 2 and 3 are not provided. As shown in Figure 2, when the products to be sorted are packed into boxes according to their classification and are transported by combining them on a single conveyor, there is It is essential to print marks for each classification on the packaging containers before they are transferred to the conveyor, so packaging workers manually stamp these marks.

[The problem that the idea aims to solve]

As mentioned above, in the conventional boxing stand, the height of the stand remains constant and unchanging when the boxing container is placed on the stand and the boxing work is carried out, so the size of the boxing container is (In addition, the containers for sorting items such as fruits and vegetables are 4Kg, 5Kg, and 10Kg).
There are various sizes such as 15Kg, 20Kg, and 4Kg, and the height is generally about 15cm for 4Kg and 50cm for 20Kg, and the minimum and maximum height is 3.
There is a height difference of more than twice that. ), or if the height of the boxer changes significantly, the height of the boxer will not match, resulting in the worker becoming easily fatigued and lowering the efficiency of the packing operation.

In addition, in conventional boxing stands, in which the conveyed products are transferred to the conveyor by the rotation of rollers that receive the boxed products of approximately constant weight, the transfer of the transported products to the conveyor is performed by the frictional force between the bottom of the boxed products and the rollers. Since the product is transported, if the size of the boxed container changes and the weight of the boxed product changes, the boxed product on the rollers may not be able to be transferred onto the conveyor, and the boxing worker must manually push it out. This had the disadvantage of low packaging efficiency.

Furthermore, in the conventional boxing stand, the boxed products are transferred to the conveyor by the boxer holding the boxed products and placing them on the conveyor.
This work was hard work and had the disadvantage of low packaging efficiency.

Furthermore, as mentioned above, the conventional boxing stand has
When a printing device was not installed and printing was essential, the boxer manually stamped the classification marks on the packaging containers, which also had the disadvantage of low packaging efficiency. Ta.

The present invention solves the above-mentioned drawbacks and can be used even if the size of the packaging container changes and its height changes, or even if the packaging worker changes and his/her height changes greatly, or the weight of the boxed product changes. Another object of the present invention is to provide an elevating boxing stand that can extremely easily carry out packaging work, including transporting boxed products and printing on packaging containers, and greatly improve packaging work efficiency. It is.

[Means to solve the problem]

In order to achieve the above object, the present invention takes the following technical measures.

That is, the present invention includes a vertical guide mounted on a column erected on a base, a table that is assembled to the guide so as to be able to be raised and lowered so that packaging containers of different sizes can be placed thereon, and a table that can be raised and lowered. when the table is lowered to a predetermined position and stopped together with a boxed container containing a predetermined classification of objects to be sorted placed on the table which is stopped at the upper limit position of the elevating device. a printing device that operates to print a mark of the predetermined classification on the side surface of the boxed container on the table, and a pushing device that pushes out the boxed container from the table onto the conveyor after printing;
After this extrusion, the table is raised and stopped by the lifting device, and the setting of the upper limit position of the table is variable.

In the present invention, preferably, the table is provided with a plurality of free rollers that are rotatable in the direction of pushing out the boxed container, and the position of the table is adjustable according to the size of the boxed container. It is preferable that a positioning guide is provided, and the lifting device has an air stroke cylinder, and lifts the table at an upper limit position set according to the height of the boxed container. It is preferable that the printing device is configured so that the printing can be stopped midway, and furthermore, it is preferable that the printing device is configured so that the printing position can be varied vertically and horizontally.

Further, in the table 4, a guide roller 44 attached to a part of a frame 46 extending toward the column 2 is fitted into a vertical guide rail 5 provided along the column 2. It is designed to be able to be raised and lowered against the ground to keep it level.
A part of the connecting part 21 of the column 2 and a part of the connecting part 45 of the table 4 are connected by a chain 34 through a foil 32, and when the foil 32 of the lifting device 3 goes up and down, it goes up and down while being held by the foil 32. It's becoming like that.

Reference numeral 35 denotes an upper limit switch for setting the upper limit position of the vertical movement of the table 4 according to the height of the packaging container and the height of the packaging worker, and is part of the lifting device 3. The mounting position of the limit switch 35 can be easily changed by a known appropriate means, and thus the setting of the upper limit position of the table 4 raised and stopped by the lifting device 3 can be changed. Reference numeral 36 denotes a lower limit switch for setting the lower limit position of the vertical movement of the table 4 to a predetermined position (a position where the upper surface of the table 4 is substantially the same horizontal plane as the upper surface of the conveyor 8), and the switches 35 and 36 are In either case, the air hydraulic cylinder 31 of the lifting device 3 is stopped by detecting a part of a cam 47 attached to a part of the frame 46 extending from the table 4 to the column 2 side.
This stop causes the table 4 to stop. The positioning guide 43 of the table 4 is adjusted and set according to the size of the boxed container when the boxed container is placed with the printed surface facing the printing device 6 side.

The printing device 6 is composed of a stand 61, a stamp arm 62, a stamp 63, and an actuating cylinder 64. The stand 61 is provided on the base 1 on the side and below the table 4, and the stand 61 is provided at the set upper limit position. Items to be sorted of a predetermined classification are packed into empty boxes placed on the stopped table 4, and this boxing is completed.Then, the table 4 is lowered to a predetermined position together with the boxes, and the lower limit container is placed on the table 4. When the limit switch 36 detects a part of the cam 47, the lifting device 3 stops operating and the table 4 stops at the same time. The mark of the specified classification is printed in the column. The stamp arm 62 has a telescopic adjustment section 65 for height (up and down) adjustment and a lateral position adjustment section 66 for left and right adjustment in order to align the stamp 63 with the printing field of the packaging container. The position of the stamp 63 can be adjusted vertically or horizontally to match the packaging container.

The extrusion device 7 consists of an air cylinder 71 and a pusher 72, and the pusher 72 pushes the table 4 toward the conveyor 8 from behind the plate surface 42 of the table 4, which is stopped at the predetermined lower limit position.
A pusher 72 is configured to appear and retract above the table 4 so as to push out the boxed container (packed product) on the top, and is activated by a printing completion signal from the printing device 6. In this way, Even if the weight of the boxed product changes considerably, the boxed product can be reliably transferred onto the conveyor 8. When starting this extrusion, if there is another boxed product being transported on the transport conveyor 8 in front of the free roller 41 provided on the table 4, the photoelectric switch 81 is activated.
When this is detected, a timer temporarily suspends operation of the extrusion device 7 for the time T required for the boxed product to pass through. Also, instead of a timer, a switch may be provided to detect the completion of passage. In the examples shown in FIGS. 8 and 9, a step stool 9 for the boxer is provided, so the push-out device 7 is disposed below the step 9 for the boxer.

As mentioned above, the lift-type boxing stand of the present invention makes it easy to carry out boxing work even if the size of the boxing container changes and its height changes, or even if the boxer's height changes. The setting of the upper limit position of the vertical movement of the table 4 can be changed by means of an upper limit switch 35. Also, table 4
A plurality of free rollers 41 are provided on the sending side, and a plate surface 4 for receiving the bottom of the packaging container is provided on the other side.
2, and is further provided with a positioning guide 43 whose position can be adjusted according to the size of the packaging container. Packing operations can be carried out easily and appropriately without causing displacement of containers. Furthermore, since the elevating device 3 for elevating and lowering the table 4 uses an air hydraulic cylinder 31, the upper limit switch 35 detects a part of the cam 47, thereby raising and lowering the table 4.
The table 4 can be stopped midway up and held at an upper limit position set according to the height of the packaging container and the height of the packaging worker.

Next, to explain the operation of the present invention, the boxer lifts the table to the upper limit position set according to his/her height and the height of the boxer and then lifts the table while it is stopped.
After placing an empty cartoning container on top and packing the material to be sorted in the set classification, when the lever of the switching valve 33 is switched to the lowering side, the air hydraulic cylinder 31 of the lifting device 3 is activated and the foil 32 is lowered. At the same time as this lowering, the boxed container containing the items to be sorted is automatically lowered together with the table 4.
When the lower limit switch 36 detects a part of the cam 47 of the table 4, the air hydraulic cylinder 31 stops operating, the wheel 32 stops descending, and at the same time the table 4 stops at a predetermined lower limit position, and at this time, printing The device 6 operates to print a predetermined classification mark such as grade or class on the printing column on the side of the boxed container placed on the table 4, and the printing push-out device 7 operates to print the boxed container (box). The packed products) are automatically pushed out and transferred onto the conveyor 8. When the extrusion is completed and the pusher 72 of the extrusion device 7 is retracted, the lever of the switching valve 33 of the elevating device 3 is automatically switched to the upward side, and the air stroke cylinder 31 is operated to raise the foil 32. At the same time, the table 4 rises, and when the lifting limit switch 35 detects a part of the cam 47 of the table 4, the air hydraulic cylinder 31 stops operating and the foil 32 stops rising, and at the same time, the table 4 moves to the boxing container. The container stops at the upper limit position, which is set at a height that is convenient for packaging work, depending on the height of the cartoner and the height of the packaging worker, and then the next packaging operation is resumed. Note that the table 4 is raised after the extrusion is completed using the switching valve 33.
The lever may be manually operated to the upward side, and this method can be used depending on the work situation of the boxer.

[Effect of idea]

As described above, the present invention is provided with a lifting device that lifts and lowers a table on which boxes of different sizes can be placed, and when the table is lowered to a predetermined position and stops, it is activated to load boxes on the table. A printing device is provided to print a predetermined classification mark on the side of the container, and a pushing device is provided to push the boxed container from the table onto the conveyor after printing. In other words, since the setting of the position where the packaging containers are placed on the table and the items to be sorted are packed into boxes is variable, there is no need for the packaging worker to manually stamp the predetermined classification marks on the packaging containers. A boxed container in which the item to be sorted is packed in a box (boxed product)
There is no need for the boxer to hold the boxed product and place it on the conveyor, and even if the weight of the boxed product changes, the extrusion device can reliably transfer the boxed product onto the conveyor. Even if the size of the packaging container changes and its height changes, or the height of the packaging worker changes, the setting of the upper limit position can be changed. It is possible to carry out the packing work at a height that makes it easy to carry out the packing operation, and together these have the effect of making the packing work extremely easy and greatly improving the efficiency of the packing work. It is.
