Description

[Detailed description of the invention] (Field of industrial application) This invention is a device for packaging can lids of canned cans, in which a partition sheet is automatically inserted into each row of can lids. This relates to a lid box packing device.

(Prior art) When can lids for canned cans are transported, for example when supplied to canners, the can lids are stacked separately from the can body to form a cylindrical body, and this cylindrical body is stacked in several rows. It is shipped in several boxes. At this time, when packaging aluminum lids, a partitioned cardboard sheet is inserted into each layer to prevent accidents such as deformation of the edge of the can lid during transportation.

Conventionally, this sheet insertion work has been carried out manually, step by step, by a worker next to the boxing device.

That is, as shown in FIG. 4, the can lid (end) has a counter sink part B rising from the bottom plate A and a flange C extending outward from the upper end of the counter sink part B. When the lids are stacked, The countersink portions B fit into each other to form a single cylindrical body. However, this fit is not very strong and is easily separated by impact. If it is separated, it will naturally become impossible to handle it as a cylindrical body due to the lid falling down, etc. Further, especially in the case of an aluminum lid, the flange portion C is easily deformed and becomes unusable as a can lid. For this reason, it is necessary to handle the can lid cylindrical body gently so as not to apply impact during the packaging operation.

There is a known device that inserts a partition sheet into each row of general articles and automatically packs them in a predetermined number of boxes. However, there was a strong possibility that the above-mentioned problems would occur due to collisions between the can lid cylindrical bodies during loading, and the device could not be used as a can lid packaging device.

(Problems to be solved by this invention) This invention attempts to obtain an automated can lid packaging device that does not cause the above-mentioned problems.

Composition of the invention (means for solving the problem) The packing device of this invention is a device that carries and orients an empty carton case having a hole in the bottom to a packing position;
A sheet receiving member provided so as to protrude freely in and out above the carton case positioned at the box-stuffing position, a stacker capable of stacking a large number of partition sheets, and the lowest one of the stackers placed in the above-mentioned position. The sheet presser is pushed out onto the sheet receptacle that protrudes directly above the carton case.
A feeder that supplies a cylindrical body of a predetermined length in which can lids are stacked, a pusher that transfers the cylindrical body onto the partition sheet on the sheet receiver, and a position where each cylindrical body is positioned above the partition sheet. It consists of a position regulating member that is provided correspondingly and contacts each of the cylindrical bodies from above to regulate the position of each cylindrical body, and a lifter that is vertically movable and inserted through a hole in the bottom of the upper carton. By detecting that a certain number of cylindrical bodies are aligned on the top, the sheet receiver is retracted, and the sheet is dropped onto a lifter or a row of cylindrical bodies located at approximately the same height as the top side of the box. , after which the lifter descends by one step.

(Function) As mentioned above, the end cylindrical bodies fit into each other at their countersink parts, so if they are pressed in the axial direction, unexpected fitting will occur and a fixed number of boxes will be produced. Therefore, it is necessary to transport a cylindrical body in which a predetermined number of ends are stacked with their axes parallel to each other, but in this case, the flange parts C, which are vulnerable to shock, come into contact with each other.

In the packaging device of this invention, the end cylinders are fed one by one by the feeder, and when they are extruded onto the sheet, they are prevented from falling onto the sheet and causing separation or deformation due to the impact. First, the sheet is held on the sheet receiver, and the cylindrical body is pushed out horizontally onto the sheet, and the position regulating member is used to prevent the cylindrical bodies from rolling on the sheet and colliding with each other. It is held in place.

After the cylindrical bodies for one stage are lined up, the sheet holder retreats, but the falling distance at this time is extremely small, and moreover, it almost fills the width of the box, so there is no risk of it rolling around too much and damaging each other. .

(Example) A detailed explanation will be given below with reference to the drawings.

The can lid packaging device uses an empty carton case 1, which has a lifter insertion hole at the bottom as described later.
A belt conveyor 2 carries the cans, a pusher (not shown) for pushing the carton case 1 into a predetermined position at the end of the belt conveyor 2, a pusher (not shown) for pushing the carton case 1 into a predetermined position, and a can inserted through the insertion opening at the bottom of the carton case 4 held in a predetermined position by a position regulating member 3. Each time the filling operation for one stage of the cylindrical body of the lid (end) is completed, the cylindrical end 8 is transferred by a predetermined length from the lifter 6, which is lowered one stage by the motor 5, and the transfer path 7. By operating the feeder 10 configured as an intermittent rotating wheel having a recess into which the end 8 fits, a stacker 11 that stores a large number of partitioned cardboard sheets, and a cylinder 12 to feed the sheets one by one to the pusher 9. , a sheet pusher 13 that pushes out the lowest partition sheet of the stacker 11 onto the carton case 4 in a predetermined position via a link mechanism; Sheet receivers 15 receive the partitioned sheet 14 on both sides, a cylinder 16 for retracting the sheet receivers 15 from above the carton case 4 and dropping the sheet 14 into the carton case 4, and a pusher 9 pushing the end 8. It consists of a position regulating member 17 which is slidably suspended up and down so as to rest on the end when canning is completed, and a pusher 19 for pushing the carton case 4 from the boxing position onto the roller conveyor 18 when canning is completed. There is. In the figure, 21 is a lifter of the table 20 on which the carton case is placed, and 22 is a regulating member that regulates the arrangement end of one stage.

The above boxing device operates as follows.

An empty carton case 1 is conveyed by a belt conveyor 2, and at its end, in the illustrated embodiment, it is conveyed by the conveyor 2 and a right angle pusher (not shown), and by a position regulating member 3, etc. It stops at the predetermined packing position. Next, the cylinder 12 is activated, and the sheet pusher 13 pushes the bottom one of the partition sheets stacked in the stacker 11 onto the sheet receiver 15. At the same time, the motor 5 starts and moves the lifter 6 to the seat receiver 1 through the drive mechanism.
5 to just below the partition sheet 14 above.

On the other hand, the ends 8 which are piled up and supplied as a cylindrical body of a predetermined length from the transfer path 7 are transferred to the pusher 9 by one operation of the feeder 10, which in the illustrated embodiment is rotated by 90 degrees. The pusher 9 pushes up the position regulating member 17 as shown by the arrow in FIG.
4 Push it up.

In this way, when it is detected that a predetermined number of ends 8 have been pushed out onto the partition sheet 14, the cylinder 16 is actuated to move the sheet receiver 15 back from above the carton case 4, and the ends 8 are pushed out onto the partition sheet 14. One stage of the end is dropped onto the lift 6 and placed there. In order to detect that a predetermined number of ends have been pushed out onto the partition sheet, an end counting device may be placed at an appropriate position within the operating range of the pusher 9, for example at 23, Various detection methods can be used, such as detecting push-up of the position regulating member 17 or detecting contact of the end 8 with another regulating member 22.

As described above, when the end stuffing for one stage is completed, the lifter 6 is lowered by one stage, and then the sheet pusher 13 pushes the sheet receiver 15 again.
The partition sheet 14 is pushed out on top, and the end of the next stage is pushed in by the pusher 9.

When the predetermined number of stages of packaging is completed in this way,
The cylinder 19 is operated, the carton case 4 at the packing position is pushed out onto the roller conveyor 18, the next empty carton case is sent to the packing position, and the packing operation is performed as described above.

Effects of the invention As mentioned above, the canning device for canning box lids of this invention not only automatically packs the ends of a predetermined row and number of stages, but also has a partition inserted between each stage. Cardboard sheets can also be inserted automatically, making it possible to reduce the number of workers due to completely automatic operation.

In particular, since it has a sheet receiving member that is removably provided at the upper end of the oriented carton case, the supplied middle partition plate can be accurately positioned on the carton, and the middle partition sheet can be placed on the sheet receiving member. Since it is supported by the can lid, it can be fed to already loaded can lids without impacting them.

Furthermore, a position regulating member is provided at the top of the partition sheet corresponding to the position where each cylindrical body is located, and contacts each of the cylindrical bodies from above to regulate the position of each cylindrical body. As a result, the can lid cylindrical bodies that are successively extruded onto the partition sheet are individually fixed at fixed positions, and adjacent cylindrical bodies do not collide with each other, making it possible to pack the cans reliably.
