Description

In the present invention, a large number of needles are arranged at intervals of 0.3 to 1.0 mm while using the width direction and the length direction of a cloth or the like on a plane, and the individual needles are controlled and pushed out to a cloth or the like having a predetermined width. A decorative needle punch processing device that can express various patterns by creating control data from image data such as geometric patterns and patterns using a device having a structure and performing needle punch processing based on the data. About.

The needle punch products currently on the market are broadly classified into needle punch carpets, mass-produced accessories by needle sewing machines, and fashion clothing in which various fibers are entangled with fabrics. Processing for fashion apparel is a plain pattern due to the mechanism of entanglement of fibers and the like by the vertical movement of a board board embedded with many needles. Punching with a board with a part of the needles removed gives a stripe pattern, but it is necessary to replace the needle according to the pattern.

Processing using a needle sewing machine is a process in which an operator manually moves the needle sewing machine, and it is possible to reveal an arbitrary pattern such as a floral pattern, but a reproducible and accurate pattern is required. It cannot be expressed, and geometric shapes such as stripes and check patterns cannot be expressed accurately. Furthermore, in order to carry out mass production, a large number of needle sewing machines are prepared, and at the same time, many workers are required, leading to a significant cost increase.

Needle punch carpets in the field of building materials and indoor equipment materials are manufactured as industrial materials, and thus there has been no particular need for patterns or the like. On the other hand, in the fashion apparel field, there is one that decorates a contour pattern using a multi-head electronic embroidery machine.
For example, Japanese Patent Application Laid-Open No. 2002-371457 (see Patent Document 1) and Japanese Patent Application Laid-Open No. 11-172666 (see Patent Document 2) describe a needle punch instead of an embroidery needle mounted on the head of a multi-head electronic embroidery machine. It is described that a needle is provided, the head and the embroidery frame are driven according to the needle punch pattern information input to the control unit, and the needle punch needle is moved up and down to perform punching.
In addition, JP 2003-64571 A (see Patent Document 3), JP 11-350328 A (see Patent Document 4), and JP 5-214658 A (see Patent Document 5) each have a punch needle. A multi-needle head that is easy to replace is described.
Further, JP-A-3-220360 (see Patent Document 6) discloses at least one stage for needle punching a stage having a thin plate lattice as an article placement board and a belt-like article conveyed through the stage. An apparatus is described for needle punching a belt-like article composed of a driven needle plate and a scraping plate between a needle plate and a thin plate lattice, which has a needle through-hole.

However, the prior art has the following problems.
Needle punch processing for fashion apparel is a plain pattern due to the mechanism of entanglement of fibers and the like by the vertical movement of a board board in which many needles are embedded. At that time, a punched pattern can be obtained by punching with a board board from which a part of the needle has been removed. However, it is necessary to replace the needle according to the pattern.

Further, even if the needles of the multi-needle board are replaced and a part of the needles are removed, the processing for expressing a pattern other than the stripe pattern cannot be performed.

On the other hand, in a multi-head type electronic embroidery machine, if a single needle is used for each electronic embroidery machine, a fine pattern can be expressed. However, the number of needles functions only for the number of electronic embroidery machines. Is significantly inferior. In order to improve this, if a plurality of needles are set in each electronic embroidery machine, the productivity is slightly improved but it becomes impossible to express a fine pattern.

Hereinafter, a preferred embodiment of a decorative needle punch processing apparatus of the present invention will be described with reference to the drawings.

As shown in FIGS. 1, 5, and 6, the decorative needle punch processing device of the present invention is arranged in a number of planes in a widthwise row and a lengthwise row of a sheet-like object 10 to be processed. A needle 11, an extruding mechanism 12 for extruding the needle 11 individually, a control mechanism 13 for generating control data from image data such as a geometric pattern and a pattern, and driving and controlling only the needle 11 at a necessary location; A feed mechanism 14 that drives and controls the processed sheet 10 in the length direction below the needle 11, and controls the push-out mechanism 12 by the control mechanism 13 to extrude only the needle 11 at a required location to process the sheet. The object 10 is subjected to needle punching so that an image such as a geometric pattern or a pattern can be reproduced on the processed sheet material 10.

As the feeding mechanism 14, a roller driving system using a pair of upper and lower rollers provided with a driving source can be suitably used.

In order to express the pattern by pushing the needle 11 toward the workpiece 10, there is a method of moving the head as in a dot impact printer. Needles need to be arranged at intervals of 0.3 to 1.0 mm in the width direction of the cloth or the like as the sheet-like material 10. However, when the needles equipped with the mechanisms for individually driving up and down are arranged in a horizontal row at intervals of 0.3 to 1.0 mm, the sheet-like material to be processed 10 is greatly damaged by pushing the adjacent needles simultaneously, and the horizontal row It is difficult to realize the arrangement at intervals of 0.3 to 1.0 mm.
In the present invention, a plurality of needles 11 arranged in a planar shape in a width direction column and a length direction row of the workpiece sheet 10 are sequentially positioned in the length direction for each column. They are staggered.
That is, in the present invention, the depth direction is also used as shown in FIG. In FIG. 1, the needles 11 are arranged at intervals of 5.0 to 10.0 mm in the horizontal direction and at intervals of 5.0 to 10.0 mm in the vertical direction, thereby controlling the amount of movement of the fabric in the vertical direction. In particular, it was possible to create a state in which 0.3 to 1.0 mm intervals were arranged in the lateral direction.

An arrangement example of the needle 11 is shown in FIG. In this example, 150 needles 11 are used that are 10 rows at intervals of 7.5 mm in the horizontal direction and 15 rows at intervals of 7.5 mm in the vertical direction.
In the arrangement, with respect to the lower right point as a reference, five rows in the vertical direction are spaced by 1.5 mm. The next sixth row is shifted by 0.5 mm from the reference, and the subsequent four rows are set at 1.5 mm intervals. The next eleventh row is shifted by 1.0 mm from the reference, and the subsequent four rows are 1.5 mm apart. In this arrangement, when 14 rows arranged at intervals of 7.5 mm in the vertical direction are translated to the reference row, 150 needles 11 are arranged at regular intervals of 0.5 mm (interval is 150-1) with a width of 74.5 mm. It will be.

In such an arrangement, in order to apply the processing to a fabric having a width of 1500 mm, if the arrangement of FIG. 2 is extended in the horizontal direction to form 200 rows at intervals of 7.5 mm in the horizontal direction, the vertical direction has an interval of 7.5 mm. Thus, 3,000 needles are arranged at a substantially horizontal interval of 0.5 mm, and processing with a width of 1499.5 mm is possible.
A large number of needles 10 arranged in a planar shape in a widthwise row and a lengthwise row of the fabric as the processed sheet-like material 10 are arranged as a unit for each predetermined number and assembled for each unit. This makes it extremely easy to manufacture the needle 11 portion.

A large number of needles 11 arranged in a planar shape in the widthwise columns and the lengthwise rows of the workpiece 10 can be controlled by the control mechanism 13 for each column and each row.
In this way, in order to express a pattern on the sheet-like object 10 to be processed, the pattern is created as monochrome bitmap data, and a portion corresponding to black in the monochrome data is processed. Using this bitmap data, the pusher mechanism 12 pushes down the needles 11 in the column in the width direction and the row in the length direction corresponding to the pattern.
At that time, the extrusion mechanism 12 is controlled by the monochrome bitmap data. The monochrome bitmap data is read by a personal computer, and an on / off signal is sent to the control mechanism 13 by serial communication from the monochrome bitmap data. The electromagnetic solenoid can be controlled by an electric circuit composed of other electronic components.
After the electromagnetic solenoid driving is completed, the drive unit of the pushing mechanism 12 including the control mechanism 13 is lowered, and the plunger and the needle can be selectively pushed down.
In addition, when the drive part of the extrusion mechanism 12 raises, a plunger and a needle will reset to an origin automatically by the effect | action of the spring which was attached to each.

A large number of needles 11 arranged in a planar shape in a widthwise row and a lengthwise row of the processed sheet-like material 10 are provided separately from the push-out mechanism 12, and only the needles 11 are appropriately attached. It can be exchanged individually.
The push-out mechanism 12 for moving the individual needles 11 up and down is appropriately connected between the drive unit 21 including a large number of stoppers 23 arranged in parallel between the plurality of plate separators 22 and between the stoppers 23 and the plate separators 22. And a needle cassette portion 41 that holds the needle 11 that is pushed down by the plunger 32.

Therefore, when each needle 11 needs to be replaced due to wear or breakage, a mechanism for transmitting the push-down action of the push-out mechanism 12 to the needle 11 is divided into the plunger 32 and the needle cassette portion 41. Therefore, it is possible to replace only the necessary needle 11 and, of course, the workability when replacing all the needles 11 is improved.

The selection of whether to drive the multiple needles 11 individually is based on whether the stopper 23 side of the electromagnetic solenoid 25 is an N pole or an S pole as shown in FIGS. This is performed by a mechanism that controls the shutter lever 24 at one end of the stopper 23 to be in an open state and a closed state. As shown in FIG. 3A, the shutter lever 24 has a structure in which a depression 29 is provided at the tip and a claw 30 or the like for preventing a side slip is formed so as to prevent the plunger 32 from coming off. it can.
The mechanism for performing this control is the combination of the plunger 32 provided in the push-out mechanism 12 and the stopper 23 that selectively stops the plunger 32, and the plunger is used by using the control data of the control mechanism. The press-down of 32 is driven and controlled, and only the needle 11 at a necessary location is pushed out to perform needle punch processing on the sheet-like material 10 to be processed.

As shown in FIG. 4, the pushing mechanism 12 uses, for example, 16 electromagnetic solenoids 25 (hereinafter referred to as an electromagnetic solenoid cassette).
That is, the electromagnetic solenoid cassette 51 in which 16 electromagnetic solenoids 25 are arranged is provided between the plate separators 22 constituting the push-out mechanism 12, and a stopper 23 for selectively stopping the plunger 32 is provided. The electromagnetic solenoid 25 and the plunger 32 are held so as to be able to swing at a fulcrum 26 provided between the plate separators 22 at a substantially intermediate position.
By setting the thickness of the electromagnetic solenoid cassette 51 used at this time to 5.0 to 10.0 mm, the plunger 32 can be arranged at intervals of 5.0 to 10.0 mm in both the horizontal direction and the vertical direction.

As described above, a mechanism in which the magnet 28 provided on the suction lever 27 at the other end of the stopper 23 is attracted by the electromagnetic solenoid 25 is used, and the pushing mechanism 12 and the plunger 32 are connected to the stopper 23 when attracted by magnetic force. When the magnetic force is repelled, the stopper 23 is removed from between the push-out mechanism 12 and the plunger 32, whereby the depression of the plunger 32 is driven and controlled.

When the pushing mechanism 12 is driven, as shown in FIG. 5, a plurality of electromagnetic solenoid cassettes 51 are used to hold the shutter lever 24 at a predetermined position in an open state and a closed state. Move up and down. Due to this vertical movement, the plunger 11 shown in FIG. 6 passes through the escape hole 52 at the position where the shutter lever 24 is opened, so that the needle 11 is not moved.
On the other hand, in the place where the shutter lever 24 is closed, the plunger 32 is pushed by the shutter lever 24, and as shown in FIG. 6, the depression of the plunger 32 is transmitted to the needle cassette portion 41, and the needle 11 is moved. It descends toward the work sheet 10.
By this operation, as shown in FIG. 1, the needle 11 is pierced by the workpiece 10 and a predetermined needle punching process is performed.

The plunger 32 has a structure in which two springs 63 are used between a spring retainer 61 and an upper and lower guide plates 62 attached at appropriate positions of the plunger 32 as shown in FIG. 32 for returning to the origin, and the upper spring 63 is for shock buffering.
Further, the needle cassette portion 41 has a structure in which one spring 73 is used between the guide plate 71 and the partition plate 72 as shown in FIG. The spring 73 is for returning the origin of the needle 11.

As shown in FIG. 9, the needle 11 has a cylindrical bush 81 having a larger diameter than the needle 11 for receiving the lower end of the plunger 32 at the upper end of the needle cassette portion 41.
As shown in FIGS. 10 to 12, the cylindrical bush 81 is provided with a notch 82 for accommodating the upper end of the needle 11 on the side surface, and the upper end opening 83 is separate from the cylindrical bush 81. The lid 84 is detachably fitted.
Reference numeral 85 denotes a ring-shaped groove provided in the cylindrical lower portion of the opening 83, which engages with the enlarged diameter portion 86 of the lid body 84 and prevents it from coming off due to the elasticity of the plastic material. .
As shown in FIG. 13, the cylindrical bush 81 accommodates a bent portion 11 a provided at the upper end of the needle 11 in a notch 82 provided on a side surface, and the lid 84 can be attached to and detached from the upper end opening 83. The needle 11 is fitted to prevent the needle 11 from coming off.
Therefore, even if the individual needles 11 are damaged and need to be replaced, the new needles 11 can be replaced very simply by disassembling the cylindrical bush 81 of the needle cassette portion 41.

FIG. 14A is a photograph of a needle punch product in which the decorative needle punch processing apparatus of the present invention is applied and the alphabet is lifted up on a processed sheet-like material such as fabric, and FIG. 14B is an enlarged photograph thereof.
In this way, in order to express a pattern on a sheet-like object to be processed, the pattern is converted into bitmap data, and the obtained bit map data is used to obtain a column and a length in the width direction of the position corresponding to the pattern. By pushing down each needle 11 in the direction row by the pushing mechanism 12, a very precise needle punch product can be obtained.

When the present invention is applied to a post-processing process of fabric, it is possible to express a bulky pattern that could only be expressed by embroidery and the like, and the range of design possibilities is widened. The availability of is very high.
Of course, the application can be applied not only to fashion clothing but also to decorative accessories, other design needle punch products, and others.
