FIELD OF THE INVENTION The present invention relates to deposition apparatus and methods useful for applying reinforcement / reinforcement or decorative powders to substrates, in particular to shoemakers producing reinforcement / reinforcement or decoration means for shoe uppers prior to assembly into the bones of the shoe. It is about process.

The shoe and clothing industry has long used reinforcement / reinforcement products. Shoes producers, as well as apparel makers that produce gloves, visor hats, sportswear, sportswear, pajamas, and blue jeans, have sewn, glued, or otherwise applied reinforcement layers to products for a variety of reasons. It has been the norm for the industry, in particular shoe producers, to use reinforcement / reinforcement means as molten thermoplastic layers adhereable to the upper. The initial attempt to reinforce the upper was to preform the reinforcement or the heel leather cut from the uniform thickness plate and insert it into the upper before assembling it into the bone. The sheet, which can be softened with heat or solvent and is separable, is inserted into the upper before assembling into the bone, molded into the bone as desired, and then hardened before removing the upper from the bone. Prior to assembling the upper into the bone, the upper may be strengthened by injecting a solution or dispersion in a volatile liquid excipient such as a hardenable reinforcement into the oral part. The upper is strengthened by assembling the shoe into the bone and then curing the infusion.

One method of strengthening the upper is described in Chaplic's U.S. Patent No. 3,316,573, in which a resiliently flexible reinforcing element in a specific portion of the upper is in a three-dimensional shape that will retain when it is deposited in the fluid phase, heated to the forming point and cooled.

Another device for covering shoe parts is shown in Camborion, US Pat. No. 33,426,24, in which a template is placed on the upper and the combination is supported on a concave support surface with a wiper blade passing over the liquid at the recessed part of the upper. Deposit the strengthening agent.

A more recent device for reinforcing shoe parts is shown in US Pat. No. 39,73285, in Bobson's group, which deposits molten thermoplastic dopant on the upper held in the edge bite device.

Conventional devices sometimes work well, but there are difficulties in producing reinforcements of uniform thickness regardless of the seam and overlapping shape. Reinforcements often do not stick well at their edges. Both rough edges and strings or spider webs of the process can exist. The machine leaks molten material at the joints, the nozzles are silent, and the model takes time and patience to deform.

Materials available for conventional machines are limited to any viscous fluid or thermal stability properties that require careful cutting and often reduce the efficiency of the final product. This particular material is also expensive.

Accordingly, an object of the present invention is an improved machine and method for forming a layer of adhesive material having a desired three-dimensional shape, such as forming reinforcement / reinforcement or decorative layers for a substrate, which overcomes the disadvantages of the prior art and in particular It is to provide machines and methods for forming in simple, clean, economical and various ways.

This invention thus provides a method of forming an adhesive material layer having a desired three-dimensional shape, with the result that an excess of fusion powder is deposited in the desired three-dimensional shape on the receiving surface. The powder is heat treated to deform into a sticky tacky material while maintaining its shape. The fused material is cooled through the receiving surface, strengthening but leaving the exposed surface sticky, compressing the conveying surface to which the material sticks and separates the material from the receiving surface towards the sticky exposed surface. The fused material is conveyed from its receiving surface.

Thus, using such a method, a controlled amount of powder can be molded into a layer of sticky material, for example for reinforcement / reinforcement or decorative parts, which layer has a desired three-dimensional shape for this purpose. With this method there is no waste of material at all, because only enough powder can be deposited to form the desired shape, but at the same time the deposition of the material can be done cleanly, and because the powder is necessarily dry, it can be easily handled. to be.

In addition, when carrying out the method, if necessary, the adhesive layer may be directly attached to the substrate by pressing a substrate such as an oral upper or coating against the fused material while the exposed surface thereof is sticky. The substrate itself then provides the transfer surface mentioned above.

To obtain the desired three-dimensional shape using the method according to the invention, it is desirable to modify the receiving surface while controlling the shape in which the powder is deposited while applying the powder to the receiving surface.

Various methods may be provided for modifying the receiving surface as such in accordance with the present invention.

The support means may provide a plurality of receiving surface portions and move to bring the receiving surface portions in sequence to the plurality of processing portions. Deposition means are disposed at the first of these sites to deposit a large amount of fusible powder in a three dimensional shape on each receiving surface site present there. The fusing means is arranged in one or more of the other areas to heat a large amount of fusible powder deposited on each receiving surface portion therein, thus maintaining the shape of the powder as a sticky sticky material. Transform. Cooling means are arranged in other portions of the portions to cool the fused material supported by each receiving surface portion therein and thus solidify the material into a three-dimensional shape.

In this way, a machine is provided which transforms the powder into a tacky layer of the desired shape by treating in sequential steps.

In addition, the machine according to the invention comprises a winding means consisting of a conveying surface which can be squeezed towards the fused material supported by the receiving surface portion, while the exposed surface is still sticky even after cooling the material as described above. It may further comprise sequential control means for causing the conveying surface to be pressed against the material. Moreover, in one embodiment the winding means consists of a support for the substrate and means for pushing the support towards the receiving surface area to support the substrate. The means thus provide a conveying surface to be pressed towards the fused material supported by the receiving surface portion.

In order to facilitate the manipulation of the formed adhesive layers, and in particular to remove the adhesive layers from the receiving surface depending on whether the adhesives are attached to a substrate or elsewhere, the winding means has a plurality of conveying surfaces (or supports). It consists of a housing which can be rotated about an axis extending substantially parallel to the plane of the receiving surface and the indexing means such that the housing together with the means for moving the housing in the height direction of the support means body It is convenient to rotate about the axis so that the receiving surface portion and the conveying surface face each other continuously. Thus, with such an arrangement, where the transfer surface is provided by the substrate, the operator simply has to place the substrates successively on the supports that appear continuously, and the rest of the work takes place automatically.

The winding means is conveniently arranged at said other of said sites. There, the cooling means is arranged under the supporting means so that the fused material is cooled through the receiving surface portion, and the winding means itself is arranged in the number of supporting units so that when the conveying surface presses the material as described above, the material together with the receiving surface It is pressed toward the cooling surface, by which the material is cooled through the receiving surface.

The support means of the machine according to the invention preferably comprises an annular support member for providing said plurality of receiving surface portions. The support member is indexable along the path to bring its face portions into a variety of regions as described above. In order to facilitate the removal of the molded adhesive layer from each receiving surface portion of the supporting means, each of such supporting surfaces is preferably coated with a non-tacky material such as polytetrafluoroethylene or the like.

It is convenient for the fusion means of the machine according to the invention to comprise one or more heaters arranged under the support means. For the heater (s) each receiving surface portion is fixed when appearing in the one or more portions. Each heater is connected to a vacuum means for pulling such a receiving surface portion toward the heater. In addition, the fusing means may comprise one or more radiant heaters disposed above the support means in the one or more regions. Each radiant heater may pivot between an operating position and other positions that illuminate a receiving surface portion disposed thereunder.

The deposition means of the machine according to the invention comprises a template means comprising cutouts matching the desired shape, means for connecting the template means to the feed powder, and dispensing the powder over the receiving surface beneath the template means. It is preferable that it is comprised by a means. Furthermore, in order to deform the receiving surface during deposition, it is preferable to provide a deforming means in the first portion, the deforming means being arranged under the supporting means and deforming the receiving surface portion to form a template onto the receiving surface portion as above.

As shown in FIG. 1, the inclined rod 200 journaled back through the rear surface of the transport box 140 is located on the radially outer side of the annular socket 167 and is in contact with the rear surface of the block 196. The inclined spring rod 201 is installed with respect to the front face of the block 196 and has a spring 203 between the front end and the front face of the transport box 140. The rear end of the rod 200 extending from the rear side of the box 140 may contact the friction ring 202 installed around the front hub 136 on the front of the gear housing 130 as shown in FIGS. 1 and 3. Are arranged to be. The rubber ring 202 is radially aligned with respect to the radial movement of the rod 200 extending rearward about the axis of rotation R in the transfer box 140. The foot 170 extending forward at the distal end of the driving leg 168 is also radially aligned with respect to the circular movement trajectory of the rod 200 extending backward from the transfer box 140 and the friction ring 202. Stand-offs 208 made of an elastic body such as rubber or the like are bonded to the outer surface of each inclined plate 187. For the particular use described in this example, the shape of the standoff 208 is the same as the outline in front of the upper.

The cold plate 120 positioned above the frame middle portion 16 under the transfer box 140 has a shape of a cooling cool connected to a freezing unit, not shown, and the plate 120 is about 0 ° C. to 37.8 ° C. There is a freezing device 121 for cooling.

The arc-shaped stop plate 212 of FIG. 3 is fixed to the frame middle portion 16 near the cooling plate 210 and the deposition portion 30, so that the rotating circular receiving belt 22, i.e., the frame middle portion near the track of the belt ( 16) Complete the circular workbench installed above.

In the method of operating the reinforcement reinforcing device, the hopper 46 at the top of the frame 14 is preferably a powder of polymer, such as ionomer, polyethylene, ethylene vinyl acetate powder, polyvinyl or nylon, together with color, filler or other additives. Precipitates in. A fine powder of about 30 mesh and a fine mesh of 50 to 100 mesh is preferable for complex and thin reinforcement decoration suitable for spreading and heating through a template.

It should also be able to adhere to substrates such as uppers, shirt collars, pajamas, knees, feet, and athletic clothing. The powder is precipitated in a hopper 46 supported on the frame top 14 of the device. The powder leaves the hopper 46 through a conduit 48 between the hopper 46 and the mobile distributor 44 on the deposit 30. This powder falls on the plate portion formed by the template 42, and the deposit 30 is stored due to the rotation of the rotary shaft 84 by the appropriate synchronous pressing action of the piston and the cylinder device 90 fixed to the upper frame 14. The surface comes down to approach the upper surface of the storage belt 22. Accordingly, the cam member 86 rotates, and the rotatable driven wheel 78 turns close thereto, and the horizontal bar member 76 to which the driven wheel 78 is attached is slightly lowered.

Therefore, the supporting bar 70 at both ends of the horizontal bar member 76 is slightly lowered, and the deposition unit 30 is lowered together with the spacer device used for the receiving belt 22. The piston and cylinder device 90 on the upper part of the frame 14 double acts, so that if a synchronous reversal occurs, the depositing portion 30 is slowly lifted from the receiving belt 22 at a suitable time and the powder therein. The three-dimensional shape in (C) advances stepwise along the arc of the arc. By proper synchronization of the double acting piston and the cylinder arrangement 102 on the middle of the frame 16, the lower support plate 100 is raised just before the deposit 30 contacts the bottom and the bottom of the receiving belt 22 is lowered. The contact will be supported. After the three-dimensionally formed powder C is deposited on the upper surface of the receiving belt 22, the switch acting as a cam to lower the lower support plate 100 immediately before the depositing portion 30 synchronously rises up is turned on. The lower guide plate 100 is directed to the proper position by the excitation guide shaft 104.

Once the lower support plate 100 has an accommodating belt 22 which is advanced in an arc shape and the support contact (deformation contact by the wedge S), the deposition part 30 is lowered to make contact with the accommodating belt 22. [More precisely, when the element spaced apart from the circumferential spacer of the blocking device at the bottom of the plate 42 comes into contact with the receiving belt 22], the lower support plate 100 and the deposition portion 30 are suitable. By means of the receiving means, when in position, it interacts with a double-acting cable cylinder 66 which receives a suitable signal for the mobile distribution device 44 to operate, and the mobile distribution device 44 is connected to the frame of the deposition section 30. 40). The wiper blades 50 provided on both sides of the moving distribution device 44 press the upper surface of the template 42, and as the moving distribution device 44 moves, the pressure is applied by the piston and the cylinder device 54. The wiper blade 50 attached to the tail portion of the mobile distribution device 44 exerts a pressing pressure and sprinkles the powder to the blocking portion of the template 42. The wiper blade 50 is reciprocated with respect to the common pivot axis so that when the distributing device 44 reverses the direction on the template 42, the lower support plate 100 goes down and the deposition part 30 goes up, and three-dimensional. When the receiving belt 22 moves in a circular arc shape stepwise to the heating part 32 together with the powder C shaped, the continuous arc-shaped advancing takes place, whereby the powder of the receiving belt 22 is separated by a 45 ° interval. The part is heated and melted to maintain a three-dimensional thick, tapered shape.

The molten powder shape goes to the cooling discharge part 38, where it is cooled from about 0 ° C to 37.8 ° C while going from bottom to bottom by the cooling plate 120 for 1-2 seconds, and melting in a three-dimensional shape from under the receiving belt 22. The powder is sticky so that if desired, it can adhere to the substrate of uppers, shirts, pajamas and sporting goods, or later lift off the storage surface or adhere to the substrate at some point in the production cycle. When the powder (C) of the three-dimensional formation is the upper or clothing of the god requiring reinforcement reinforcement, it is preferable to receive the substrate 140 from the transport box. When the receiving belt is 45 ° battery, the conveyance box 140 is rotated 90 ° while the two parts are related to each other via the paired gear 131 in the gear housing 130, as shown in FIG. It provides a substrate (U) supported by the cross-delivery container 140 to the powder (C) shape of the cold plate 120 to synchronously press the parts together. Due to the synchronous pressing action of the double acting piston and the cylinder device 160 in the upper frame 14, the fused shape of the powder C in the cooling plate 120 arrives in a timely manner. To move.

The driver of the gas 10 is a separator 186 fixed in the twelve o'clock position in the grooves 184 in the compartments 180 and 182 of the transport box 14, the standoff 208 and the inclined plate that are elastically molded. Place a new (non-reinforced) substrate in the outside (top when filling) of (187). Driving a piston and cylinder device 172 having a piston rod 174 pivotally connected to a drive distance 168 behind the transport box 140 presses a foot (not shown) with the driver's foot while the inclined plate 187 Retreats toward the rotation axis R of the transfer box 140. The foot 170 at the distal end of the drive leg 168 is thus pressed forward (toward the front of the transport box 140), one for each inclined plate 186 on the surface of the transport box 140 and two of the transport box 140. Extending rearward from and parallel to the friction ring 202 in a radial direction to push the inclined bar 200 at 12 o'clock. The foot 170 thus pushes the inclined bar 200 forward, thereby hinged the pin 194 for fixing the first lever 192 and the second lever 198 together.

Due to the influence of the pins 194 fixed at both ends of the levers by the grooves 195 of the block 196, the block 196 and the inclined rod 201 move in axial direction to compress the spring 203 and the inclined plate 187. ) Move radially. When the operator operates the start switch 17, the feed box 140 is rotated about the axis ＂R＂ center, and then the inclined bar 200 moves from the 12 o'clock position to the counterclockwise direction as the friction ring 202 moves. And the inclination plate 187 as well as the levers 192 and 198 are pressed at the six o'clock position as shown in FIG. 1 just before the actuation / pressurization of the piston cylinder 160, and the substrate 140 is pressed. The shoe upper UU shown in FIG. 1 is fixed relative to the shape of the powder XC on the receiving belt 22 supported by the cooling plate 120. The powder ＂C＂ fused into a three-dimensional shape is then compressed by the elastic standoff 208 and produced as a product alone, or on a flexible substrate fixed between the grooves of the elastic standoff 208 and the bracket 186. And adhere to the substrate. Subsequently, when the transfer box 140 is advanced from the 12 o'clock direction to the 3 o'clock direction about the rotation shaft 270, the inclined bar 200 is released from contact with the friction ring 202. Subsequently, the inclined plate is removed from the load shape to remove the resilient pad 208 from behind the flexible substrate and from the grooves of the barrier plate 186 so that the operator can remove the newly reinforced or reinforced substrate fabric, leathers as desired. Can be.

As the feed bin 140 is rotated further by 90 ', the unloaded and unbiased sloping plate 187 is the top position 12 that pushes and fills the next substrate between the resilient pad 208 and the recess of the blocking plate 186. Position).

EXAMPLE

A) A preferred use of the invention is to reinforce and strengthen the upper. Sodium cation type 35-45 mesh ionomer powder has no additives at the melt index 2.5, the bending rate 51000 psi, and the thermal softening temperature (Vicat) 63 ° C. The pattern template is prepared to the specific shape desired and placed on an 8 mesh screen woven of 0.38mm stainless steel wire. The choice of 8 mesh screens is based on the following elements:
