Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine for making a hole for draining water in a joint between a bottom surface and a side surface of a flowerpot made of synthetic resin such as plastic.

[0002]

2. Description of the Related Art Conventionally, when a hole is made in a plastic flower pot, it is made by using a metal pot receiving member having a recess at the portion where the blade hits.

[0003]

When a hole is made using a conventional metal bowl receiving member, if the relative position of the bowl receiving member and the cutting tool is slightly shifted, the cutting tool hits the edge of the recess of the bowl receiving member. , The blade could be damaged. Therefore, there is a drawback that the position of the bowl receiving member must be accurately set, the work is difficult, and the manufacturing cost of the metal bowl receiving member is expensive. Further, it is very difficult to change the positions of a plurality of cylinder devices equipped with blades according to the size of the flower pot.

The present invention has been invented to solve the above problems in the prior art, and when a hole is formed, the blade is not damaged even if the position of the bowl receiving member is slightly displaced. In addition, when changing the position of a plurality of cylinder devices equipped with a blade, it is intended to provide a plastic flowerpot opening machine configured so that it can be changed to an accurate position by a simple operation. is there.

[0005]

A plurality of support bases are installed on the upper surface of a turntable provided on the upper surface of a machine base, and a bowl receiving member is fitted on each of the upper bases of the turntables to form a plastic. The flower pot can be fitted downward, and a slide block for holding a cylinder device equipped with a blade for opening the flower pot is installed on the pillar extending upward from the side of the machine base. And the position of the machine relative to the center of the machine can be changed easily.Furthermore, the blade contact portion of the pot receiving member fitted on the upper part of the support for supporting the flower pot is made of rubber or elastic material. It is formed of an elastic body of synthetic resin having.

[0006] In the above-mentioned plastic flower pot opening machine, the disk-shaped scale plate provided in contact with the upper part of the slide block for holding the cylinder device equipped with the blade for opening the flower pot is A plurality of slide blocks are provided by penetrating the same number of arc-shaped openings toward the periphery as the number of slide blocks, inserting the spindles at the upper ends of the slide blocks into the openings, and rotating the scale plates. The position from the center of the blade can be changed to the same position at the same time, and the position of the blade can be changed to the same position accordingly.

[0007]

Since the blade contacting portion of the bowl receiving member is formed of the elastic body of rubber or synthetic resin having elasticity, the blade will not be damaged when it contacts.

When the scale plate is rotated, all the slide blocks provided by inserting the support shafts into the arc-shaped openings formed in the scale plate move, and after the movement, all the slide blocks are also displaced from the center. It is the same distance.

[0009]

Embodiments of the present invention will be described with reference to the drawings.
Six support bases 3 for supporting the flower pots are provided on the upper surface of the peripheral edge of the circular turntable 2 provided on the machine base 1, and the fitting members 4 are fitted on the respective upper parts, Further, a pot receiving member 5 made of rubber is fitted on the pot for receiving the plant pot. The lower half of the pot receiving member 5 has a cylindrical shape, and the upper half has a slightly smaller diameter from the lower portion to the upper portion, so that the plastic flower pot P can be fitted downward.

On a column 6 extending upward from the side of the machine base 1, four slide blocks 9 for holding a cylinder device 8 equipped with a blade 7 for opening a plastic flowerpot P are radially provided. Is provided at the upper part of the slide block 9 so that it can be moved up and down by an air cylinder 18 provided at the top, and a spindle 10 is projectingly provided at the upper end of the slide block 9, and a disc-shaped scale plate 11 is provided above the spindle 10. Has four arcuate openings 12 extending from the vicinity of the center toward the periphery at four equal positions, and the spindles 10 of the four slide blocks 9 are inserted into the openings 12. When the scale plate 11 is rotated, the four slide blocks 9 move to the same distance from the center. Also, on the peripheral side surface of the scale plate 11,
A scale is provided so that you can check the rotation position.

The grease plate 13 provided in contact with the upper portion of the scale plate 11 is provided with eight concave portions 14 on the lower central surface thereof, and the springs 15 and the balls 16 are contained therein. 16 concave portions 17 are also provided on the upper surface of the scale 11, and the scale plate 1
When 1 rotates, the ball 16 enters the recess, and the top and bottom of the ball 16 that stops rotating at the stop position enter the recesses of the scale plate 11 and the grease plate 13 and are temporarily fixed. Has become.

As shown in FIG. 8 (A), the bowl receiving member 4 is made entirely of rubber, and as shown in FIG. 8 (B), the upper half is formed into a planar multi-sided shape. Further, as shown in FIG. 8 (C), the main body is made of plastic, and a recess 21 having a diameter slightly larger than the diameter of the blade is provided at the portion where the blade abuts. The fitting member 19 may be fitted. Furthermore, instead of the above rubber, an elastic body of synthetic resin having elasticity may be used.

In the plastic flower-pot opening machine of the present invention, when a hole for draining water is to be formed in the connecting portion between the bottom surface and the side surface of a plastic flower pot, as shown in FIGS. The pot receiving member 5 is fitted onto the support base 3 installed in the above via the fitting member 4, the plastic flower pot P is fitted thereon, and the blades 7 provided at the four positions of this machine are put into the flower pot. It is installed so as to face the planned opening portion of P, air is sent to the cylinder device to advance the blade 7, and it is pressed against the flower pot to open it. In this example, 6 flower pots are installed on the turntable 2 and
When the opening work of the individual pieces is completed, the turntable 2 is sequentially rotated, and when the opening work of the six pieces is completed, an unprocessed flower pot is installed and the opening work pieces are sequentially formed.

When opening flowerpots of different diameters,
First, the reinforcing plate 2 fixing the four slide blocks 9
0 is removed, the scale plate 11 is slightly rotated as described above, and the relative positions of the four blades 7 are adjusted to perform the work. When the position adjustment of the blade 7 is completed, the lower ends of the four slide blocks 9 are fixed to the reinforcing plate 20 with bolts. Further, several kinds of pot receiving members 5 having different diameters are prepared, and the pot receiving members 5 suitable for the size of the flower pot are used.

[0015]

In the plastic flower pot opening machine of the present invention, the flower pot is received by the pot receiving member mounted on the support for supporting the plastic flower pot, and the blade which penetrates the flower pot is provided. Since the tip end of the blade is formed of rubber or plastic having elasticity, the portion contacting the bowl receiving member is not obstructed, and damage to the blade can be prevented. Further, there is an advantage that it is not necessary to strictly set the position of the bowl receiving member, the operation is easy, and the manufacturing cost is lower than that of a metal member.

When the positions of a plurality of blades are changed according to the diameter of the flower pot, the positions of the blades can be simultaneously moved by the same distance by a simple operation of slightly rotating the scale plate. , There is an advantage that the position can be set accurately.
