Description

Technical Field

[0001] The present invention relates to a production device for clothing or shoe materials, in particular to a labeling device and a labeling machine having the labeling device. Background Art

[0002] In the production of clothing or shoe materials, it is often necessary to hot-press rubber labels on the fabric, and this process is usually achieved by a labeling device. Existing labeling devices usually use a hot stamping head to press the label and the fabric tightly on a placement board to achieve hot pressing. When the label thickness is uneven (such as when the label surface has concave and convex shapes, etc.), it is difficult to ensure the uniformity of heat and force received by the label, which affects the bonding effect between the label and the fabric.

[0003] In view of this, the applicant of the present invention has conducted in-depth research on the structure of the labeling device, and thus this case has arisen. Summary of the Invention

[0004] The purpose of the present invention is to provide a labeling device with relatively good bonding quality and a labeling machine having the labeling device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A labeling device includes a bracket, and also includes two support plates fixedly connected side by side on the bracket, a placement board fixedly connected at the upper ends of the two support plates and arranged horizontally, a hot stamping head located directly above the placement board, and a hot pressing cylinder for driving the hot stamping head to move up and down. A through hole is provided at the middle position of the placement board, and an inflation joint is connected to the lower end of the through hole. A heat-resistant leather is placed on the placement board, and a locking frame for pressing the periphery of the heat-resistant leather against the placement board is attached above the heat-resistant leather.

[0007] As an improvement of the present invention, a pressing cylinder with a vertically upward piston rod is fixedly connected to each support plate, and a pressing plate arranged parallel to the placement board is fixedly connected to the piston rod of each pressing cylinder.

[0008] As an improvement of the present invention, the hot stamping head includes a heating plate, a pressing aluminum plate fixedly connected to the lower end of the heating plate, and a heating element installed on the heating plate. Adsorption holes are provided at the lower end of the pressing aluminum plate, and an air suction channel communicating with the adsorption holes is provided on the pressing aluminum plate.

[0009] As an improvement of the present invention, it also includes a label delivery mechanism installed on the bracket, the label delivery mechanism includes a suspended plate in a horizontal position and a label taking robot located below the suspended plate, the suspended plate is provided with a first long hole and a second long hole intersecting in a cross shape, and the suspended plate is fixedly connected with a first support located on the same vertical plane as the first long hole and a second support located on the same vertical plane as the second long hole, a first slide seat respectively located on both sides of the second long hole is slidably inserted in the first long hole, and a second slide seat respectively located on both sides of the first long hole is slidably inserted in the second long hole, and the A first screw is rotatably connected to the first support, and a second screw is rotatably connected to the second support, the first screw has two first screw segments with opposite spiral directions, two first slides are spirally connected to the two first screw segments one-to-one, the second screw has two second screw segments with opposite spiral directions, and two second slides are spirally connected to the two second screw segments one-to-one, each of the first slides and each of the second slides is fixedly connected to a surrounding rod located below the suspended plate, the surrounding rods together surround a material storage space, and the lower end of each surrounding plate is fixedly connected or integrally connected with a protrusion protruding toward the material storage space.

[0010] As an improvement of the present invention, one of the surrounding rods includes an upper rod section and a lower rod section, the upper end of the upper rod section is fixedly connected to the corresponding sliding seat, and an upper connecting block is provided on the side of the lower end facing away from the material storage space, the upper end surface of the lower rod section abuts against the lower end surface of the upper rod section, and a lower connecting block rotatably connected to the upper connecting block is provided on the side of the upper end of the lower rod section facing away from the material storage space, and the lower end is connected to the protrusion.

[0011] A labeling machine comprises a workbench, on which are provided a first labeling device and a second labeling device arranged side by side and a display located between the first labeling device and the second labeling device, wherein the first labeling device, the second labeling device and the display together surround a working area, and the first labeling device is the above-mentioned labeling device.

[0012] As an improvement of the present invention, the structure of the first labeling device is the same as the structure of the second labeling device.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects:

[0014] 1. By opening a through hole on the storage plate and covering it with heat-resistant leather, when the hot stamping head is pressed down, pressurized gas is introduced into the through hole to make the heat-resistant leather squeeze the label toward the hot stamping head. Since the heat-resistant leather is flexible, it can ensure that the force and heat between the label and the hot stamping head are as uniform as possible, and the bonding quality is relatively good.

[0015] 2. A storage space is formed by surrounding with a surrounding rod. The label picking manipulator picks up the label from below the storage space. After picking up, the label located in the storage space can naturally fall under the action of gravity, without setting an independent driving mechanism, with relatively low power consumption, and without setting a falling stroke according to the thickness of the label. The label picking position of the label picking manipulator is not affected by the thickness of the label, and the picking accuracy is relatively high, which is convenient to use.

[0048] The present invention will be further described below in conjunction with specific embodiments:

[0049] As Figure 1 shown, this embodiment provides a labeling machine, which includes a workbench 100. On the workbench 100, a first labeling device 200 and a second labeling device 300 arranged side by side, and a display 400 located between the first labeling device 200 and the second labeling device 300 are provided. The display 400 is a conventional display, mainly used to display the working states of the two labeling devices. The first labeling device 200, the second labeling device 300 and the display 400 jointly form a working area on the workbench 100. The working area is mainly used to provide an operating space for the operator, so that the operator can control the two labeling devices to work simultaneously when needed, thereby improving production efficiency.

[0050] The structure of the first labeling device 200 and the structure of the second labeling device 300 may be exactly the same or different. In this embodiment, the structures of the two are different, which helps to expand the applicable range of the labeling machine. It should be noted that the first labeling device 200 and the second labeling device 300 provided in this embodiment can also be used independently, that is, this embodiment actually provides two labeling devices.

[0051] As Figures 1-3 shown, the first labeling device 200 includes a bracket 210, two support plates 220 fixedly connected side by side to the bracket 210, a placement plate 130 fixedly connected to the upper ends of the two support plates 220 and arranged horizontally, a hot stamping head 240 located directly above the placement plate 230, and a hot pressing cylinder 250 for driving the hot stamping head 240 to move up and down. Among them, the support plates 220 and the placement plate 230 can be two parts or two parts of an integral part. The support plates 220 and the bracket 210 can be directly fixedly connected to each other or can be relatively fixedly connected by fixedly connecting both of them to the same table or other components.

[0052] A through hole is provided in the middle of the placement plate 230, and an inflation joint is connected to the lower end of the through hole. During use, the inflation joint is connected to a gas source (this gas source is not part of this embodiment and needs to be configured separately during use) to provide air pressure. A plate-shaped heat-resistant leather with certain stretchability (not shown in the figure) is placed on the placement plate 230, and the heat-resistant leather can be directly purchased from the market. A locking frame 231 for pressing the periphery of the heat-resistant leather against the placement plate 230 is attached above the heat-resistant leather. Specifically, the locking frame 231 is a square frame, which is locked to the placement plate 230 by bolts to achieve a sealed connection between the periphery of the heat-resistant leather and the placement plate 230.

[0053] Preferably, a pressing cylinder 262 with its piston rod vertically upward is fixedly connected to each support plate 220, and a pressing plate 263 arranged parallel to the placement plate 230 is fixedly connected to the piston rod of each pressing cylinder 262. This is to press the fabric tightly to prevent the fabric from shifting during the hot pressing process. In this embodiment, for the convenience of assembly, extension plates 232 that cooperate with the pressing plates 263 one by one are respectively provided on both sides of the placement plate 230. The extension plates 232 are indirectly fixedly connected to the support plates 220 by being fixedly connected to the cylinder body of the corresponding pressing cylinder 263. During use, the fabric is clamped between the corresponding pressing plate 263 and the extension plate 232.

[0054] The hot stamping head 240 can be the hot stamping head adopted by a conventional labeling device. Preferably, in order to prevent the label from shifting during the hot stamping process and affecting the accuracy of its pasting position, in this embodiment, the hot stamping head 240 includes a heating plate, a pressure-feeding aluminum plate 241 fixedly connected to the lower end of the heating plate, a heating element installed on the heating plate, and an outer cover 242 covering the heating plate and the heating element. Among them, adsorption holes are formed at the lower end of the pressure-feeding aluminum plate 241, and an air suction channel communicating with the adsorption holes is formed on the pressure-feeding aluminum plate 241. During use, the air suction channel is connected to a vacuum pumping device (this vacuum pumping device is not part of this embodiment and needs to be configured separately during use).

[0055] The specific transmission connection structure between the hot stamping cylinder 250 and the hot stamping head 240 can be a conventional structure. In this embodiment, the cylinder body of the hot stamping cylinder 250 is fixedly connected to the bracket 210. The piston rod of the hot stamping cylinder 250 is arranged vertically downward, and the lower end of the piston rod of the hot stamping cylinder 250 is fixedly connected to a horizontally arranged lifting plate 251. A guide rod 252 vertically slidably connected to the bracket 210 is fixedly connected to the lifting plate 251, and four vertically arranged sliding rods 253 are slidably inserted through the lifting plate 251. The four sliding rods 263 are respectively located at the four corner positions of the lifting plate 251. The upper end of each sliding rod 263 is fixedly connected to a lifting block (not shown in the figure) located above the lifting plate 251 to prevent the sliding rod 263 from disengaging from the lifting plate 251 under the action of gravity. The lower end of each sliding rod 263 is fixedly connected to the hot stamping head to drive the hot stamping head to lift and lower. A compression spring 254 is also sleeved on each sliding rod 263 and is located between the hot stamping head and the lifting plate 251.

[0056] Preferably, the first labeling device 200 further includes a label feeding mechanism 270 installed on the bracket 210. It should be noted that the label feeding mechanism 270 provided in this embodiment is also used for other labeling devices, that is, this embodiment also provides a label feeding mechanism.

[0057] The label feeding mechanism 270 provided in this embodiment includes a suspended plate 271 in the horizontal position and a label picking manipulator 280 located below the suspended plate 271. Among them, a first long hole 272 and a second long hole 273 that intersect in a cross shape are formed on the suspended plate 271, and a first support 274 located in the same vertical plane as the first long hole 272 and a second support 275 located in the same vertical plane as the second long hole 273 are fixedly connected to the suspended plate 271. A first sliding seat 276 located on both sides of the second long hole 273 is slidably inserted into the first long hole 272, and a second sliding seat 277 located on both sides of the first long hole 272 is slidably inserted into the second long hole 273. A first screw 278 is rotatably connected to the first support 274, and a second screw 279 is rotatably connected to the second support 275. The first screw 278 has two first screw segments with opposite spiral directions, and the two first sliding seats 276 are helically connected to the two first screw segments one by one. The second screw 279 has two second screw segments with opposite spiral directions, and the two second sliding seats 277 are helically connected to the two second screw segments one by one. In this way, by rotating the first screw 278 or the second screw 279, the two first sliding seats 275 or the two second sliding seats 277 can be driven to slide towards or away from each other. To facilitate the rotation of the screw, a handwheel 290 is fixedly connected to one end of each of the first screw 278 and the second screw 279.

[0058] A surrounding rod 291 located below the suspended plate 271 is fixedly connected to each of the first sliding seats 276 and the second sliding seats 277. The surrounding rods together form a storage space for stacking labels, and a convex block protruding towards the storage space is fixedly connected or integrally connected to the lower end of each surrounding plate 291. The convex blocks are located at the same horizontal position to support the labels. Preferably, in order to facilitate the placement of the labels into the storage space, in this embodiment, one of the surrounding rods 291 includes an upper rod section 292 and a lower rod section 293. The upper end of the upper rod section is fixedly connected to the corresponding sliding seat, and an upper connecting block 294 is arranged on the side of the lower end away from the storage space. The upper end surface of the lower rod section 293 abuts against the lower end surface of the upper rod section 292, and a lower connecting block 295 rotatably connected to the upper connecting block 294 by a pin is arranged on the side of the upper end of the lower rod section 293 away from the storage space, and a convex block is connected to the lower end; in this way, during normal use, the lower rod section 293 naturally hangs down under the action of gravity, and when the label needs to be placed, the lower rod section 293 is rotated upwards to form a feeding port.

[0059] The label picking manipulator 280 can be a conventional multi-joint manipulator. Preferably, the label picking manipulator 280 includes a mounting base 281 fixedly arranged opposite to the suspended plate 271, a rotating rod 282 rotatably connected to the mounting base 281 and vertically arranged, a rotating motor (not shown in the figure) for driving the rotating rod 282 to rotate, an arm rod 283 fixedly connected to the upper end of the rotating rod 282 and horizontally arranged, and a pneumatic suction cup 284 mounted on the arm rod 283. It should be noted that in this embodiment, the pneumatic suction cup 284 is directly fixedly connected to the arm rod 283 and its working end is arranged vertically upward. Of course, if necessary, the pneumatic suction cup 284 can also be mounted on the arm rod 283 through a rotating cylinder so that the pneumatic suction cup 284 has the function of turning up and down.

[0060] In the initial state, the upper surfaces of the bumps and the pressure-feeding aluminum plate 241 are on the same horizontal plane, and the upper end surface of the pneumatic suction cup 284 is slightly lower than the above-mentioned horizontal plane. When in use, move the pneumatic suction cup 284 of the label picking manipulator 280 below the storage space, and then start the pneumatic suction cup 284 to adsorb the label at the bottom of the storage space downward. The label elastically deforms under the adsorption force, falls off from the bumps and is adsorbed on the pneumatic suction cup 284. Then move the pneumatic suction cup 284 below the pressure-feeding aluminum plate 241, turn on the vacuum pumping device connected to the suction channel, and at the same time close the pneumatic suction cup 284 so that the label on the pneumatic suction cup 284 is adsorbed on the pressure-feeding aluminum plate 241. Then the label picking manipulator 280 and the hot stamping head 240 move downward to perform the hot stamping action. After hot stamping for a period of time, introduce pressurized gas into the through hole so that the heat-resistant leather squeezes the label towards the hot stamping head. Since the heat-resistant leather is flexible, it can ensure as much as possible that the force and heat received between the label and the hot stamping head are uniform, and the bonding quality is relatively good; preferably, the hot stamping head resets, and the whole labeling process.

[0061] Such as Figure 4 And Figure 5As shown, similar to the first labeling device 200, the second labeling device 300 also includes a bracket 210, two support plates 220 fixedly connected to the bracket 210 side by side, a second placement plate 330 fixedly connected to the upper ends of the two support plates 220 and horizontally arranged, a hot stamping head 240 located directly above the second placement plate 30, and a hot pressing cylinder 250 for driving the hot stamping head 240 to move up and down. Different from the first labeling device 200, the second labeling device 300 further includes a lateral movement cylinder 360 respectively installed on each support plate 220 with its piston rod horizontally arranged, a connecting plate 361 fixedly connected to the piston rod of each lateral movement cylinder 360, a pressing cylinder 262 respectively installed on the upper part of each connecting plate 361 with its piston rod vertically arranged, and a pressing plate 263 fixedly connected to the piston rod of each pressing cylinder 262. That is to say, there are two lateral movement cylinders 360, connecting plates 361, pressing cylinders 262, and pressing plates 263 respectively. Among them, the piston rods of the two lateral movement cylinders 360 face the same direction.

[0062] A perforation is formed on the second placement plate 30 between the two pressing plates 263, that is, the two pressing plates 263 are respectively located on both sides of the perforation. The perforation is vertically arranged and slidably connected with a suction plate 331. The suction plate 331 is provided with adsorption holes for adsorbing the label placed on the suction plate 331. Between the two support plates 220, a lifting cylinder 332 for driving the suction plate 331 to slide up and down is provided. Preferably, in this embodiment, a lifting block 333 is fixedly connected below the suction plate 331. The lifting block 333 is provided with an air suction channel communicating with each adsorption hole on the suction plate 331. During use, the air suction channel is connected to a vacuum device (this vacuum device is not part of this embodiment and needs to be configured separately during use). The cylinder body of the lifting cylinder 332 is relatively fixedly arranged with the support plate 230, and the piston rod of the lifting cylinder 332 is vertically upward and fixedly connected to the lifting block 333.

[0063] Both of the two pressing plates 263 are located above the second placement plate 330 to press the fabric placed on the second placement plate 330. Preferably, each connecting plate 361 is further fixedly connected with a clamping plate 364 respectively located directly below the corresponding pressing plate 263. The two clamping plates 364 are respectively located on both sides of the second placement plate 330, and the upper surfaces of the two clamping plates 364 are flush with the upper surface of the second placement plate 330. It should be noted that the flush arrangement here not only includes the situation where the upper surfaces are on the same plane, but also includes the situation where the upper surface of the clamping plate 364 is slightly higher or slightly lower than the upper surface of the second placement plate 330. In this way, not only can the fabric be pressed by the pressing plate 263 during the hot pressing process, but also the fabric can be moved by the cooperation of the pressing plate 263 and the clamping plate 364 after the hot pressing is completed to avoid sticking of the material.

[0064] The hot stamping head 240 used by the second labeling device 300 can be the hot stamping head used by a conventional labeling device, or can be the hot stamping head 240 with the same structure as the first labeling device 200. However, adsorption holes and air suction channels may not be opened in the pressing aluminum plate 241 (of course, opening the adsorption holes and air suction channels does not affect the use either).

[0065] Preferably, the second labeling device further includes a label supply assembly 370 fixedly connected to the frame 210 and a second label picking manipulator 380 for conveying the label from the label supply assembly 370 to the suction plate 331. Among them, the label supply assembly 370 includes a bottom plate 371 and four enclosing plates 372 respectively fixedly connected to the bottom plate 371. The bottom plate 371 is directly or indirectly fixedly connected to the frame 210, and two support plates 220 are indirectly fixedly connected to the frame 210 through being fixedly connected to the bottom plate 371. The four enclosing plates 372 are arranged perpendicular to each other in pairs in the clockwise or counterclockwise direction, and jointly surround a storage space for stacking labels. A push rod 373 is vertically slidably connected to the bottom plate 371 at a position corresponding to the storage space, and a driver (not shown in the figure) for driving the sliding of the push rod 373 is arranged below the bottom plate 371. The driver can be a conventional driver, such as a cylinder, an electric push rod or a motor, etc., which will not be elaborated here. Preferably, in this embodiment, a cross-shaped sliding groove is opened in the bottom plate 371 at a position corresponding to the storage space, and a connecting bolt (not shown in the figure) for locking the enclosing plate 372 to the bottom plate 371 is inserted into the cross-shaped sliding groove. Specifically, the push rod 373 slidably penetrates through the middle position of the cross-shaped sliding groove and divides the cross-shaped sliding groove into four groove sections. At least one locking bolt is inserted into each groove section. The four enclosing plates 72 are arranged in one-to-one correspondence with the four groove sections, and each enclosing plate 372 is locked to the bottom plate 371 through the locking bolt in the corresponding groove section. In this way, only by loosening and sliding the locking bolt can the position of the corresponding enclosing plate 372 be adjusted, and then the size of the storage space can be adjusted according to actual needs to adapt to labels of different specifications.

[0066] The second label picking manipulator 380 includes a telescopic cylinder 381 with a horizontally arranged piston rod and a pneumatic suction cup 284 fixedly connected to the piston rod of the telescopic cylinder 381. Among them, the length direction of the piston rod of the telescopic cylinder 381 is the same as the arrangement direction of the label supply assembly 370 and the second placing plate 330, and the movement track of the pneumatic suction cup 284 passes above the label supply assembly 370 and the second placing plate 330. The piston rod of the crosswise moving cylinder 360 is arranged parallel to the piston rod of the telescopic cylinder 381.

[0067] Before use, stack the labels in the storage space. Lower the suction plate 331 to form a positioning groove together with the side wall of the perforation. During use, first use the second label picking manipulator 380 to adsorb a label from the storage space and send it into the above positioning groove. At the same time, move the pushing rod 373 upward by the thickness of a label to lift the stacked labels in the storage space upward for the next adsorption by the pneumatic suction cup 284. Then, manually place the fabric on the second placement plate 330, align the position where the fabric needs to be labeled with the above positioning groove, and then use the pressing plate 263 to press the fabric tightly on the second placement plate 330 to prevent the fabric from moving. Next, lower the label ironing head 240 and press it tightly against the fabric. At the same time, move the suction plate 331 upward to press both the label and the fabric tightly against the label ironing head 240 for ironing treatment. After the ironing treatment is completed, the label ironing head 240 returns to its original position, and the suction plate 331 continues to move upward to a position flush with the upper surface of the second placement plate 330 or slightly higher than the upper surface of the second placement plate 330, so that the positioning groove disappears, ensuring that the label will not be stuck in the positioning groove. Then, extend the piston rod of the transverse movement cylinder 360 to push the fabric clamped between the pressing plate 263 and the clamping plate 364 to move relative to the second placement plate 330 to prevent the fabric from adhering to the second placement plate 330. Next, the pressing plate 263 returns to its original position to release the fabric, completing the entire labeling process.
