Description

[Detailed description of the invention] (Purpose of the invention) (Industrial application field) The present invention is applicable to fluids packed in cans, such as food oil or automobile oil, or powder or granules (hereinafter referred to as
These are simply called containers. ) When using or collecting cans (hereinafter simply referred to as collection), it relates to a can removal machine that makes a hole to take out the contents from those cans.

(Prior art) Conventionally, when collecting the contents packed in the can,
A worker used a hammer with a sharp tip to make removal holes and air holes in the top and bottom plates of the can (can removal) and collect the contents inside the can.

(Problem to be solved by the invention) However, when there are a huge number of cans, a lot of manpower is required, and the work is simple and difficult, and on the other hand, it takes a lot of time. It was inefficient and required a lot of effort.

On the other hand, the removal hole formed by the above-mentioned can removal is a so-called "burr" 11 on the inside of the can C.
(See FIG. 6), the contents inside the can cannot be completely discharged, resulting in a reduction in the recovery rate of the contents or a pollution problem when the can is disposed of.

The present invention was developed in view of the above-mentioned current situation, and by providing a can extraction machine having the configuration described below, it is possible to extract a large amount of can contents in a short period of time and without waste (loss). The purpose is to provide canning machines.

(Structure of the invention) (Means for solving the problem) The can removal machine according to the invention includes a driving means and a reciprocating member that is moved up and down by the driving means even when the height is higher than the height of the can to be removed. A can removal bar is attached to the lower end of the reciprocating member for removing cans, and a pressing plate is positioned below the reciprocating member via a spring to press the cans downward during can removal. The can is placed below the holding metal fitting and the can removal bar so that the top and bottom plates of the can are located within the movement of the lifting stick. The can removal rod is configured to penetrate the top plate and bottom plate of the can from above to below when removing the can.

(Function) Therefore, the can removing machine configured as described above,
When a can to be removed is placed on the above-mentioned placing means and the driving means is activated, the reciprocating member descends from above, and as the reciprocating member descends, the presser metal lowers and the presser plate first holds the can. The can removal rod is lowered as the reciprocating member is lowered, and the cans placed by the placing means are lifted upward by pressing downward and fixing. The can is extracted from the can so as to penetrate through the top and bottom plates of the can.

After that (after can removal), the reciprocating member rises, and the can removal rod and then the holding metal fitting move upward (separated) from the can, and one time of can removal is completed.

In the can that has been removed in this manner, the burr on the bottom plate of the can protrudes downward, and as a result, all contents within the can can be discharged downward.

(Example) Hereinafter, an example of the present invention will be described in more detail with reference to the drawings.

Figure 1 is a front view of the can removal machine according to the present invention, Figure 2
The figure is a perspective view showing the shape of a can removal bar of a can removal machine.

In the figure, A is a can removal machine, B is the machine base, C is a can, 1 is a can extraction bar, 2 is a presser, 3 is a reciprocating member, 4 is an air cylinder serving as a driving means, and 5 is a spring.

The cylinder 4b portion of the air cylinder 4 is attached to the machine base B so that the rod 4a portion of the air cylinder 4 can expand and contract downward, and the air cylinder 4 is at least as high as the height of the can to be removed. It has more than h steps. The air cylinder 4 is fixed to the reciprocating member 3 at the lower end of the rod 4a, and two can removal rods 1 are attached to the center of the lower surface of the reciprocating member 3. Further, a through hole 3a is formed at both ends of the reciprocating member 3, and a cylindrical body 3A having an axial length longer than the height h of the can to be removed is fixed to the upper part of the through hole 3a. There is. In the through hole 3a, a guide rod 2A having a disc-shaped collar 2a with a diameter slightly smaller than the diameter of the through hole is installed.
is inserted into the cylindrical body 3A so as to slide vertically therein, and a coil spring 5 is inserted above the flange 2a in the cylindrical body 3A. Through hole 3b with the same diameter
An upper end plate 3B having an upper end plate 3B is fixed to support the upper end portion of the coil spring 5 above. still,
The air cylinder 4 is connected to a compressor (not shown) through air piping.

Further, in the case of this embodiment, the tip end 1a of the can removal rod 1 has a small cross-sectional area at the leading end and a predetermined cross-sectional area necessary for can removal at the rear end, as shown in FIG. It is formed in a shape whose cross-sectional area changes.

Therefore, the main can removing machine A having the above-mentioned configuration operates as follows when removing cans. That is, place the can C to be removed at a predetermined position of the can removal machine of the main can removal machine,
When compressed air at a predetermined pressure is supplied to a supply port (not shown) on the extension side of the rod 4a of the air cylinder 4, the rod 4a descends and the presser plate 2B of the presser metal fitting 2 comes into contact with the can C. Therefore, the holding plate 2B is
It stops at that position, and only the reciprocating member 3 and the can removal rod 1 integrally attached thereto are guided by the guide rod 2A of the holding fitting 2 and descend, penetrating the upper plate of the can C from above to below. (take out the can). At this time, as the reciprocating member 3 descends, the presser metal fitting 2, which is stopped at the position where it abuts the can C, is pressed downward via the coil spring 5 within the cylindrical body 3A of the reciprocating member. Therefore, the can C to be removed will remain at a predetermined position during removal. In this state, the can removal rod 1 continues to descend and penetrates the bottom plate of the can C from above to the bottom (can removal). Figure 5 shows the "burr" 11 of can C caused by the above-mentioned can removal.
The situation is shown below.

When the can removal is completed, compressed air at a predetermined pressure is supplied to the supply port (not shown) on the contraction side of the rod 4a of the air cylinder 4, and the reciprocating member 3 (can removal rod 1)
rises to its initial position. At this time, make sure that the can C does not move until the can removal rod 1 is removed from the can C.
The presser metal fitting 2 presses the can downward.

Next, an embodiment in which the can removing machine A is used as a can removing means of a can removing device will be described. FIG. 3 is an overall plan view of a can removing device using the present can removing machine, and FIG. 4 is a view taken along the line X--X in FIG. 3.

is formed. A main can removal machine A is installed slightly in the center of the starting end of the collection table 10 so that two can removal bars 1 are positioned above the cans C arranged in two rows. (See Figures 3 and 4).
The starting end of the center guide rail is formed into a pointed shape in order to smoothly arrange the cans C (see FIG. 3). From the beginning of collection platform 10,
In order to sequentially transport the cans C to the terminal end of the collection table after passing through a predetermined can extraction position on the collection table 10 below the can extraction machine A, the starting end of the collection table 10 is equipped with a pusher plate 9a at the tip of the rod. A pusher 9 consisting of an air cylinder 9b is attached.

Each of the conveyors, air cylinders, stoppers, pushers, etc. described above is controlled by a control device so as to operate in conjunction with the can removal cycle of the can removal machine or in accordance with the can removal capacity. That is, in the workstation S section, the cans C are placed on the slat plate of the supply conveyor 7, and the cans C are turned upside down and taken out of the box (in this embodiment, they are lined up horizontally in four rows on the conveyor 7). Once placed, the conveyor 7 intermittently conveys it to the placing device 8 side. When the can C is transferred onto the transfer device 8, the stopper 8c is released while the intermittent feeding of the conveyor 7 is suspended, and the air cylinder 8a with the pusher plate 8b attached is moved onto the conveyor. 6 side to transfer the can C on the transfer device 8 onto the conveyor 6. When the above-mentioned transfer is completed, the stopper 8c is lowered and the next can C (plurality) is carried into the transfer device 8 from the conveyor 7. on the other hand,
The can C transferred to the conveyor 6 is transferred to the conveyor 7.
In synchronization with the intermittent feeding, they are sequentially and intermittently conveyed to the terminal end side of the conveyor 6. During such intermittent feeding, when the air cylinder 9b becomes contracted due to the reciprocating movement of the air cylinder 9b, the stopper 6a is released and the can C is placed at the starting end on the collection table 10.
