It is a front view which shows the structure of the drilling apparatus 100 shown in a) seen from the X direction.

An object of the present invention is to obtain a perforating device capable of easily pulling out a perforating needle from an object to be processed in a state where a perforating needle for making a hole in the surface of the object to be processed is pierced into the object to be processed.
A device 100 for drilling holes in the surface of the object P to be processed.
A mounting table 100c on which the object P to be processed is placed, and
A drilling head 100a for drilling a hole in the object to be processed P mounted on the mounting table 100c, and
A drilling head moving mechanism 100b for moving the drilling head 100a forward and backward with respect to the mounting table 100c is provided.
The drilling head 100a is
Base member 110 and
A plurality of drilling needles 130 fixed to the base member 110,
It is solved by providing an apparatus including a needle penetrating member 120 having a plurality of needle penetrating holes 120b through which a plurality of perforating needles 130 can penetrate.

In such a device, as shown in FIGS. 1A and 1B, a plurality of drilling needles 130 fixed to the base member 110 penetrate the needle through hole 120b of the needle penetration member 120. It becomes possible to insert (pierce) into the object to be processed P with. Therefore, when the perforated needle 130 pierced into the object to be processed P through the needle penetrating member 120 is pulled out from the object to be processed P, the perforated needle 130 is immersed in the needle penetrating hole 120b of the needle penetrating member 120, so that the perforated needle 130 Will surely be pulled out from the object P to be processed.

Therefore, the apparatus 100 of the present invention includes a perforation head 130 for making a hole in the object to be processed P, a mounting table 100c for the object to be processed P, and a perforation head moving mechanism 100b, and the perforation head moving mechanism 100b is the object to be processed. The perforation head 100a is moved back and forth with respect to the mounting table 100c of P, and the perforation head 100a includes a plurality of perforation needles 130, a base member 110, and a needle penetrating member 120, and a plurality of perforation needles 130 fixed to the base member 110. The other configuration is not particularly limited as long as it is configured to be able to penetrate a plurality of needle through holes 120b of the needle penetration member 120.

(Processed object P)
For example, the object to be treated may be any material, such as a food material, a resin material, and wood, as long as it is possible to make a hole in the surface. For example, foodstuffs include vegetables, fruits, fish bodies (especially sardines, eels, sardines, etc. for baking and cooking), and edible livestock (meat chickens, pigs, cows, etc.).

(Mounting stand 100c)
The mounting table is not particularly limited as long as it can mount the object to be processed, and may have any configuration. For example, the mounting table may be only the base body that does not move, the mounting table may be equipped with a moving mechanism such as a conveyor, or the mounting table may be equipped with a rotating mechanism. There may be.

In one embodiment, the mounting table may include a table body and a rotary table rotatably attached to the table body. In this case, the mounting table may be configured so that the center of rotation of the rotary table coincides with the center of the drilling head, or the center of rotation of the rotary table is offset from the center of the drilling head. May be. Here, the center of the drilling head is the center of the array of plurality of drilling needles 130 fixed to the drilling head.

The rotation angle of the rotary table can be arbitrary. For example, it may be arbitrarily rotatable between 0 ° and about 360 °, or rotate (rotate) only within a predetermined range such as 0 ° to about 180 ° and 0 ° to about 90 °. It may be something to do.

Also, the drive source can be arbitrary. For example, it may be automatic such as an electric motor, an air motor and a hydraulic motor, or it may be manual by human power.

The offset direction and spacing can be arbitrary.

The material of the rotary table may be a metal main body such as stainless steel or copper and a resin sheet attached to the surface of the main body, or the entire rotary table may be made of a metal material or a resin material. It may be formed or may be only a resin material. In one embodiment, when the object to be treated is a food material, it is preferably a material having high antibacterial properties.

Further, the mounting table may include a table body and one or more spacer members that can be installed on the table body. By providing the spacer member, it is possible to adjust the interval when the perforated head comes closest to the mounting surface of the mounting table.

The member constituting the mounting table may include a metal material such as stainless steel or copper, or a resin material such as vinyl chloride resin, acrylic, ABS resin (acrylonitrile, butadiene, styrene resin), butadiene resin, or PTFE resin. It may contain. In a preferred embodiment, it is a vinyl chloride resin that is resistant to acidic or alkaline detergents and disinfectants for sterilization.

(Punch head 100a)
As described above, the drilling head includes a base member, a plurality of drilling needles, and a needle penetrating member, and a plurality of drilling needles fixed to the base member can penetrate a plurality of needle penetrating holes formed in the needle penetrating member. As long as it is configured, the other configurations are not particularly limited and may be arbitrary.

For example, the base member constituting the drilling head may have a needle mounting plate to which the drilling needle is fixed and a plate reinforcing material for reinforcing the needle mounting plate. Here, the base member, the drilling needle, and the needle penetrating member may be made of the above-mentioned metal material or resin material. However, in consideration of weight reduction, it is desirable that the needle mounting plate is made of resin and the plate reinforcing material is a metal plate thinner than the needle mounting plate.

Further, the fixing of the drilling needle to the base member may be arbitrary. For example, it may be fixed by press-fitting one end of the perforated needle into the mounting hole formed in the base member, or by screwing the male screw portion formed in one end of the perforated needle into the screw hole formed in the base member. It may be present, or it may be fixed by welding or an adhesive.

Here, the specific structure of the drilling needle is not particularly limited as long as it can make a hole in the object to be processed, and is arbitrary. For example, the cross-sectional shape of the drilling needle may be a substantially circular shape, a substantially elliptical shape, or the like, or may be a substantially triangular shape, a substantially rectangular shape, a substantially polygonal shape, or the like.

Further, the size of the hole (outer diameter) of the drilling needle may be arbitrary depending on the type and size of the object to be processed. In one embodiment, when the object to be treated is a food material such as eel, the pore size is about 0.1 mm to about 1.0 mm, preferably about 0.2 mm to about 0.8 mm, and more preferably. It can be from about 0.3 mm to about 0.5 mm. If the outer diameter is smaller than about 0.1 mm, the strength is weak and the needle easily breaks. Further, if the outer diameter is about 1.0 mm or more, it can be confirmed that holes are provided on the surface of the object to be processed, and when the object to be processed is a food material or the like, the appearance is deteriorated. Further, there arises a problem that nutrients and the like of the object to be treated leak to the outside more than necessary.

Further, the number of holes of the plurality of drilling needles and the spacing between the holes may be arbitrary depending on the type and size of the object to be treated. In one embodiment, when the object to be treated is a food material such as eel, the distance between adjacent holes may be about 2 to about 5 times the hole (outer diameter) of the perforated needle. Further, in a preferred embodiment, the arrangement of the plurality of perforated needles is staggered.

When the cross-sectional shape of the puncture needle is rectangular, it is preferable that the distance between the needles is the same as or wider than the length in the longitudinal direction of the puncture needle. When the cross-sectional shape of the puncture needle is rectangular, if the distance between the needles is narrower than the longitudinal length of the puncture needle, the force for pressing the puncture needle against the object to be processed increases, and the force is manually increased. Work becomes difficult.

Further, the drilling head may have a connecting mechanism for connecting the base member and the needle penetrating member so that the plurality of drilling needles can appear and disappear from the plurality of needle penetrating holes of the needle penetrating member. The connecting mechanism for connecting the base member and the needle penetrating member in this way may be provided in the drilling head moving mechanism instead of the drilling head. That is, the drilling head moving mechanism may be configured to support the drilling head so that the base member and the needle penetrating member are connected to each other.

Further, the drilling head may further include a vibration generator that vibrates the base member. By vibrating the base member, the perforation needle also vibrates, which makes it easier for the perforation needle to pierce the object to be processed. The direction of vibration may be arbitrary. For example, the perforation head may be vibrated in a direction along the direction in which the perforation head advances or retreats, or may be vibrated in a direction different from the direction in which the perforation head advances or retreats (for example, in a direction perpendicular to the direction).

Further, when the drilling head has a vibration generator, the drilling head has a connecting mechanism for connecting the base member and the needle penetrating member so that the plurality of drilling needles can appear and disappear from the plurality of needle penetrating holes of the needle penetrating member. Further, it is preferable that the drilling device has a driving means for operating the vibration generator when the plurality of drilling needles protrude from the plurality of needle through holes.

With such a configuration, the perforated needle automatically vibrates when the perforated needle penetrating the needle penetrating member comes into contact with the object to be processed, and unnecessary vibration of the perforated needle can be prevented, and the work cost can be reduced. It is possible to reduce the amount.

(Punching head moving mechanism 100b)
The specific configuration of the drilling head moving mechanism is not limited as long as the drilling head is moved back and forth with respect to the mounting table, and may be arbitrary.

The drilling head moving mechanism may be, for example, a mechanism for moving the drilling head in parallel in the vertical direction on the mounting table, or a mechanism for rotating the drilling head around a horizontal rotation axis on the mounting table. The drive source of the drilling head moving mechanism may be arbitrary. For example, it may be automatic such as an electric motor, an air motor and a hydraulic motor, or it may be manual by human power.

Further, the drilling head moving mechanism may have an urging means for urging the drilling head in a direction corresponding to the distance of the drilling head from the mounting table (head separation distance). For example, it may be an urging means that always generates an urging force in a direction in which the distance of the drilling head from the mounting table is long, or an urging means in which the urging force is always generated in a direction in which the distance of the drilling head from the mounting table is short. It may be an urging means whose urging force changes according to the distance between the mounting table and the drilling head.

For example, in the case of an urging means that always generates an urging force in a direction in which the distance of the drilling head from the mounting table is long, high safety can be obtained because the drilling head does not approach the mounting table against the intention of the operator. It will be possible.

Further, in the case of an urging means that always generates an urging force in a direction in which the distance of the drilling head from the mounting table is approaching, it is possible to reduce the force when the drilling head of a worker or the like is brought closer to the mounting table.

Further, in the urging means whose urging force changes according to the distance between the mounting table and the piercing head (for example, at a distance where the piercing head is moved to a position near the position where the piercing needle of the piercing head comes into contact with the object to be processed, the mounting is carried out. The urging force is generated in the direction in which the piercing head is farther from the pedestal, and the urging force disappears at the position where the piercing needle of the piercing head comes into contact with the object to be processed, and the piercing needle of the piercing head becomes the object to be processed. In the distance that moves from the contact position to the position where it is inserted into the object to be processed, an urging force is generated in the direction in which the distance of the drilling head from the mounting table approaches), so that the work force can be maintained while maintaining safety. It is possible to reduce it.

Specifically, the urging means is connected to the perforation head so that, for example, when the perforation head is at a position of the first distance from the mounting table, the perforation head rises against the weight of the perforation head. Elevate the operating arm.

The urging means loses the urging force against the operation arm when the drilling head is at a position of a second distance shorter than the first distance from the mounting table.

The urging means urges the operation arm connected to the drilling head so that the drilling head descends when the drilling head is at a position of a third distance shorter than the second distance from the mounting table. be. Here, the position of the first distance, the position of the second distance, and the position of the third distance are defined as follows.

Here, the position of the second distance is the position of the drilling head when the needle penetrating member of the drilling head is in the vicinity of contact with the object to be processed.

The position of the first distance is the position of the drilling head when the needle penetrating member of the drilling head is farther from the mounting table than when the drilling head is at the position of the second distance.

The position of the third distance is the same as when the drilling head is in the position of the second distance and the distance between the needle penetrating member of the drilling head and the mounting table, but the position of the base member of the drilling head is the position of the drilling head. Is the position of the drilling head when it is closer to the mounting table than when it is at the position of the second distance.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In the first embodiment, as an example of the drilling device (device for drilling holes in the surface of the object to be processed) of the present invention, the object to be treated is a fresh fish (specifically, a material for grilling eel). The eel body), the mounting table has a table body and a rotary table, the drilling head has a vibration generator, and the base member of the drilling head has a needle mounting plate and a plate reinforcing material. Then, the drilling head moving mechanism moves the drilling head vertically on the mounting table. Further, the drilling head moving mechanism of the first embodiment shall have a urging means for urging the drilling head in a direction corresponding to the distance of the drilling head from the mounting table.

Further, in the second embodiment, as another example of the drilling device (device for drilling holes in the surface of the object to be processed) of the present invention, a table body and a spacer member are used instead of the mounting table of the punching device of the first embodiment. Examples of the punching device include a mounting table having a mounting table, and further provided with a punching head moving mechanism for rotating and moving the punching head on the mounting table, instead of the punching head moving mechanism of the punching device of the first embodiment. Unlike the urging means of the first embodiment, the perforation head moving mechanism of the second embodiment has an urging means for urging the perforation head in a direction that always keeps the perforation head away from the mounting table against its own weight. do.

Further, the urging cylinder 107b includes a cylinder body 71 and an extension rod 72 protruding from the cylinder body 71, and is configured so that the extension rod 72 generates an urging force in a direction protruding from the cylinder body 71. Here, one end (upper end) of the urging arm 107a is fixed to one end of the rotating shaft 102 by welding or the like, and the other end (lower end) of the urging arm 107a is the urging cylinder 107b. One end of the cylinder body 71 is connected, and the tip of the extension rod 72 protruding from the other end of the cylinder body 71 is connected to the mounting bracket 107c.

In the drilling head moving mechanism 100b provided with the urging means 107 having such a configuration, the urging means 107 has the following functions.

In a state where the base member 110 of the drilling head 100a is separated from the mounting table 100c and the distance between the two is the first distance D1 (see FIG. 10), the urging means 107 opposes the weight of the drilling head 100a and is the drilling head. The operation arm 104 is urged so that 100a rises. This is because, when the separation distance between the base member 110 of the drilling head 100a and the mounting table 100c is the distance D1, the drilling head moving mechanism 100b has the central axis L1 of the urging arm 107a and the central axis L2 of the urging cylinder 107b. Since is designed to form a predetermined angle, when the extension rod 72 of the urging means 107 is extended in this state, a counterclockwise moment on the paper surface of FIG. 10 acts on the rotating shaft 102. This is because the operation arm 104 fixed to the rotating shaft 102 pulls up the elevating rod 105.

In a state where the base member 110 of the drilling head 100a is located at a second distance D2 shorter than the first distance D1 from the mounting table 100c (see FIG. 8), the urging means 107 exerts an urging force on the operating arm 104. Disappear. This is because, when the separation distance between the base member 110 of the drilling head 100a and the mounting table 100c is the distance D2 (<D1), the drilling head moving mechanism 100b has the central axis L1 of the urging arm 107a and the urging cylinder 107b. Since the central axis L2 of the above is designed to be aligned with each other, even if the extension rod 72 of the urging means 107 tries to extend in this state, the rotating shaft 102 is rotated clockwise on the paper surface of FIG. This is because neither the counterclockwise moment nor the counterclockwise moment is generated, and as a result, the urging force by the urging means 107 against the operation arm 104 rotatably attached to the rotating shaft 102 is not generated. Further, here, in the connecting mechanism 140 for connecting the base member 110 and the needle penetrating member 120, the needle penetrating member 120 is processed by the needle penetrating member 120 when the base member 110 of the drilling head 100a is at the second distance D2 from the mounting table 100c. It is configured to be located in the vicinity of contact with the body P.

Further, in a state where the base member 110 of the drilling head 100a is at a position of a third distance D3 (<D2) shorter than the second distance from the mounting table 100c (see FIG. 11), the urging means 107 is a drilling head. The operation arm 104 is urged so that the 100a descends. This is because, when the separation distance between the base member 110 of the drilling head 100a and the mounting table 100c is the distance D3, the drilling head moving mechanism 100b has the central axis L1 of the urging arm 107a and the central axis L2 of the urging cylinder 107b. Since is designed to form a predetermined angle, when the extension rod 72 of the urging means 107 is extended in this state, a clockwise moment on the paper surface of FIG. 11 acts on the rotating shaft 102. This is because the operating arm 104 fixed to the rotating shaft 102 pushes down the elevating rod 105.

The members constituting the drilling head moving mechanism 100b, that is, the support column 101, the fixed boss 101a, the fixed arm 106, the rotating shaft 102, the elevating rod 105, the operation arm 104, the urging arm 107a, the urging means 107, and From the viewpoint of strength, the mounting bracket 107c is preferably made of the above-mentioned metal material such as stainless steel, but from the viewpoint of weight reduction, the above-mentioned resin material which is lighter than the metal may be used.

7 to 9 are views showing a specific structure of the drilling device 100 shown in FIG. 2, and is a top view showing the structure of the drilling device 100 in the drilling standby state shown in FIG. 2 as viewed from the Z direction. FIG. 8 is a side view of the drilling device 100 in the drilling standby state shown in FIG. 2 as viewed from the Y direction, and FIG. 9 is a front view showing the structure of the drilling device 100 in the drilling standby state shown in FIG. 2 as viewed from the X direction. Is.

In these FIGS. 7 to 9, the layout of each member constituting the drilling device 100 described with reference to FIGS. 2 to 6 is shown in more detail.

Next, the operation of the drilling device 100 of the first embodiment will be described.

10 to 12 are diagrams for explaining a specific structure of the drilling device 100 shown in FIG. 2, respectively, and FIG. 10 shows a mounting table instead of the drilling device 100 in the drilling standby state shown in FIG. The side views showing the drilling device 100 in the drilling standby state in which the object to be processed P can be placed on the 100c, FIGS. 11 and 12, are on the mounting table 100c instead of the drilling device 100 in the drilling standby state shown in FIG. It is a side view and the front view which shows the piercing apparatus 100 in the operating state which pierced the piercing needle 130 into the object P to be placed placed in.

(Standby state of drilling device 100)
In the standby state of the drilling device 100, the drilling head 100a is lifted to the uppermost end of the support column 101 by the drilling head moving mechanism 100b as shown in FIG. In this standby state, a space is widened above the mounting table 100c so that the drilling head 100a does not interfere with the work of placing the object to be processed P on the mounting table 100c.

Further, in this standby state, the central axis L2 of the urging cylinder 107b of the urging means 107 forms a predetermined angle with respect to the central axis L1 of the urging arm 107a. That is, the connection point between the urging cylinder 107b and the urging arm 107a is located on the right side of the straight line connecting the lower end of the urging cylinder 107b and the upper end of the urging arm 107a. Therefore, the protruding output of the extension rod 72 of the urging cylinder 107b becomes the rotational force of the counterclockwise rotation of the rotating shaft 102, and this rotational force acts on the operating arm 104 as the urging force for lifting the operating arm 104. Moreover, in this case, an urging force slightly larger than the urging force to which the operating arm 104 can support the own weight of the drilling head 100a via the elevating rod 105 acts on the operating arm 104.

As a result, in the standby state, the drilling head 100a is held near the uppermost end of the support column 101 by the urging force of the urging means 107 against the operating arm 104 unless the operator operates the operating arm 104. Therefore, it is possible to prevent the drilling head 100a from being unintentionally lowered toward the mounting table by an operation by an operator or the like, and it is possible to improve safety.

In this standby state, the operator places the object to be processed P on the surface (mounting surface) of the rotary table 12 of the mounting table 100c (see FIG. 10), holds the arm grip portion 104a of the operating arm 104, and holds the operating arm 104. When is pulled down, the operation arm 104 rotates clockwise around the rotation shaft 102 in opposition to the urging force of the urging means 107 against the operation arm 104, and the drilling head connected to the operation arm 104 via the elevating rod 105. The 100a descends toward the rotary table 12 of the mounting table 100c.

By pulling down the operation arm 104 in this way, the angle formed by the central axis L2 of the urging cylinder 107b of the urging means 107 and the central axis L1 of the urging arm 107a approaches about 180 °, so that the urging means After the urging force of the 107 on the operating arm 104 gradually decreases and the urging force becomes smaller than the own weight of the drilling head 100a, the drilling head 100a is affected by its own weight without the operator pulling down the operating arm 104. It will descend. In that case, the operator needs to lift the operation arm 104 upward with a slight force so that the drilling head 100a does not descend vigorously. The pulling force of the operation arm 104 includes not only the weight of the drilling head 100a but also the weights of the elevating rod 105 and the operation arm 104 connected to the drilling head 100a. The pulling force is the weight of the drilling head 100a.

After that, when the connecting support column 141 of the drilling head 100a lands on the support column 11a of the mounting table 100c, the descent of the drilling head 100a is stopped, and as shown in FIGS. 8 and 9, the drilling device 100 performs the drilling operation. It becomes the standby state (drilling standby state).

(Punching standby state of the drilling device 100)
In the drilling standby state of the drilling device 100, as shown in FIG. 8, the angle formed by the central axis L2 of the urging cylinder 107b of the urging means 107 and the central axis L1 of the urging arm 107a is approximately 180 °. Therefore, the urging force of the urging means 107 against the operating arm 104 is almost non-existent.

Further, in the drilling standby state, the base member 110 is held at a position separated from the needle penetrating member 120 by the urging force of the return spring 142 of the connecting mechanism 140 against its own weight. As a result, in the drilling standby state, the plurality of drilling needles 130 attached to the base member 110 are held in a state of being immersed in the needle penetrating holes 120b of the needle penetrating member 120 as shown in FIGS. 8 and 9.

(Operating state of the drilling device 100)
When the operator operates the arm grip portion 104a of the operation arm 104 in the drilling standby state, the rotating shaft 102 rotates clockwise, so that the elevating rod 105 descends and the urging arm 107a rotates clockwise. do.

By lowering the elevating rod 105 in this way, as shown in FIGS. 11 and 12, the base member 110 moves in a direction approaching the needle penetrating member 120, and a plurality of perforations fixed to the base member 110. The needle 130 projects from the needle through hole 120b of the needle penetration member 120 and moves toward the surface of the object to be processed P. At this time, the central axis L2 of the urging cylinder 107b of the urging means 107 and the central axis L1 of the urging arm 107a form a predetermined angle as shown in FIG. That is, the connection point between the urging cylinder 107b and the urging arm 107a is located on the left side of the straight line connecting the lower end of the urging cylinder 107b and the upper end of the urging arm 107a.

As a result, the protruding output of the extension rod 72 of the urging cylinder 107b becomes the rotational force for clockwise rotation of the rotating shaft 102, and this rotational force acts on the operating arm 104 as an urging force for pulling down the operating arm 104. Therefore, the urging force of the urging means 107 against the operation arm 104 acts as a force for the tip of the drilling needle 130 to pierce the surface of the object to be processed P, and an operator or the like causes the tip of the punching needle 130 to be the tip of the object P to be processed. It is possible to reduce the operating force required to pierce the surface.

Further, when the tips of the plurality of drilling needles 130 protrude from the needle penetration holes 120b of the needle penetration member 120 due to the lowering of the base member 110, the pressing lever 108a attached to the needle mounting plate 111 of the base member 110 is used to drive the means 108. The operation piece 108b will be pressed. As a result, the vibration generator 117 is operated by the driving means 108 to give vibration to the drilling needle 130 via the base member 110.

When the perforation needle 130 pierces the surface of the object to be processed P, the vibration of the perforation needle 130 makes it easier for the vibration generator 117 to pierce the surface of the object to be processed P, and the perforation needle 130 is pierced by the object to be processed P. The operation force of the operator when piercing the needle is reduced.

FIG. 13 is a plan view for explaining how to use the rotary table 12 of the drilling device 100 shown in FIG. 2, and FIG. 13 (a) shows a object to be processed placed on the rotary table 12 at a reference position. The positional relationship between the body P and the needle through hole 120b of the needle penetration member 120 is shown, and FIG. 13B shows the hole H1 formed in the object to be processed P at the reference position of the rotary table 12.

As described above, in the drilling device 100 in the drilling standby state, FIG. 13A shows the workpiece P placed on the rotary table 12 at the reference position and the needle through hole 120b of the needle penetration member 120. The positional relationship with and is as shown in FIG. 13 (a). In this state, by pulling down the operation arm 104, a plurality of drilling needles 130 of the drilling head 100a are pierced into the surface of the object to be processed P. As shown in 13 (b), a plurality of holes H1 are formed on the surface of the object to be treated P.

After that, when the operator lifts the operation arm 104 upward, the base member 110 moves in a direction away from the needle penetrating member 120, and the drilling needle 130 attached to the base member 110 is pulled out from the object P to be processed. Moving. At this time, even if the perforation needle 130 and the object to be processed P both move upward while the perforation needle 130 is stuck in the object to be processed P, the object to be processed P abuts on the needle penetrating member 120 to be processed. The body P will be wiped off from the drilling needle 130. As a result, the drilling needle 130 can be easily pulled out from the object to be processed P.

Then, after returning the operating arm 104 to the standby position of the drilling device 100, the operating lever 12a abuts the operating lever 12a of the rotary table 12 from one lever stopper 12b and the operating lever 12a abuts on the other lever stopper 12b. The operation is performed so that the state is reached, and the operation arm 104 is pulled down again.

FIG. 13C shows the positional relationship between the object to be processed P placed on the rotary table 12 at the rotation position and the needle penetration hole 120b of the needle penetration member 120, and FIG. 13D shows rotation. The hole H2 formed in the object P to be processed at the rotation position of the table 12 is shown.

As shown in FIG. 13 (c), in the punching device 100 in the standby state, by rotating the rotary table 12 and then pulling down the operation arm 104 again, the plurality of drilling needles 130 of the drilling head 100a are subjected to the processed body P. As shown in FIG. 13B, a plurality of holes H2 are formed on the surface of the object to be treated P at a position different from the plurality of holes H1 already formed.

FIG. 14 shows a hole H1 (solid line display) formed in the object to be processed P at the reference position of the rotary table 12 and a hole H2 (dotted line display) formed in the object to be processed P at the rotation position of the rotary table 12. It is the figure which shows by superimposing.

In this way, the work of making a hole in the surface of the object to be processed P at the reference position of the rotary table 12 is performed, and then the rotary table 12 is rotated to make a hole H2 in the surface of the object to be processed P at the rotation position of the rotary table 12. As shown in FIG. 14, many holes H1 and H2 can be easily formed on the surface of the object to be treated P by performing the work of opening.

By offsetting, the needle that punctures the object to be processed is not always the only needle at the same position, so multiple needles are used evenly, and it is possible to maintain the sharpness of the needle.

Further, when the cross-sectional shape of the drilling needle 130 is a shape other than a substantially circular shape or a square shape, various patterns can be formed by offsetting.

As described above, in the perforation device 100 of the first embodiment, the perforation head 100a for drilling holes in the mounting table 100c on which the object to be processed P is placed and the epidermis of the object to be processed P placed on the mounting table 100c. The perforation head 100a is provided with a perforation head moving mechanism 100b for advancing and retreating the perforation head 100a with respect to the mounting table 100c. It includes a needle penetrating member 120 having a plurality of needle penetrating holes 120b through which the needle 130 can penetrate.

Therefore, in the drilling device 100 of the first embodiment, the plurality of drilling needles 130 fixed to the base member 110 can be pierced into the object to be processed P in a state of penetrating the needle penetration hole 120b of the needle penetration member 120. When the perforated needle 130 pierced into the object to be processed P is pulled out from the object to be processed P, the perforated needle 130 is immersed in the needle through hole 120b of the needle penetrating member 120, so that the perforated needle 130 is surely inserted from the object to be processed P. It is pulled out.

As a result, in the perforation device 100 of the first embodiment, the perforation needle 130 can be easily pulled out from the object to be processed P in a state where the perforation needle 130 for forming a hole in the surface of the object to be processed P is pierced into the object to be processed P. The effect is obtained.

Further, in the drilling device 100 of the first embodiment, the mounting table 100c includes the rotary table 12, and the rotation center of the rotary table 12 is configured to be offset from the center of the drilling head. The work of making a hole in the surface of the object to be processed P is performed at the reference position of 12, and then the operation of rotating the rotary table 12 to make a hole H2 in the surface of the object to be processed P at a position different from the reference position. As a result, more holes can be easily formed on the surface of the object to be treated P.

Further, since the drilling head moving mechanism 100b has an urging means 107 for urging the drilling head in a direction corresponding to the distance (head separation distance) of the drilling head 100a from the mounting table 100c, the drilling head 100a is mounted on the mounting table 100c. Since the head separation distance when performing the work of approaching to the head and the head separation distance when performing the work of inserting the drilling needle 130 of the drilling head 100a into the object to be processed P are different, the operator's operation can be performed in each working state. It is possible to urge the drilling head 100a in the assisting direction, and it is possible to reduce the force of an operator or the like required for the operation for drilling work.

Further, since the perforation head 100a includes a vibration generator 117 that vibrates the base member 110 to which the plurality of perforation needles 130 are attached, the vibration of the base member 110 when the perforation needle 130 pierces the surface of the object to be processed P. The perforation needle 130 fixed to the base member can also be vibrated, which makes it easier for the perforation needle 130 to pierce the object P to be processed.

In the first embodiment, the drilling device 100 includes a drilling head moving mechanism 100b for moving the drilling head 100a in parallel in the vertical direction on the mounting table 100c, but the drilling head moving mechanism is a drilling head. A drilling head moving mechanism 200b for rotating 100a around a horizontal rotation axis on a mounting table may be used, and the following second embodiment describes a drilling device 200 provided with such a drilling head moving mechanism 200b.

(Embodiment 2)
FIG. 15 is a perspective view for explaining the drilling device 200 according to the second embodiment of the present invention, and shows the appearance of the drilling device 200.
