Description

Technical Field

[0001] The invention relates to an embedding device, which can be particularly used for embedding air hole sleeves on air holes in tire molds. Background Art

[0002] In the production process of tires, a series of processes are performed on rubber materials to achieve tire embryo molding. After the tire embryo is molded, the tire embryo needs to be vulcanized. During the vulcanization process, the air in the inner cavity of the tire mold needs to be discharged. The commonly used method at present is to set an exhaust hole on the tire mold, and the air in the tire mold is directly discharged through the exhaust hole. The exhaust hole is formed by a method such as drilling.

[0003] During the vulcanization of the tire blank, it was found that only providing vent holes for exhaust would cause some problems. For example, during the process of exhausting air from the tire mold, the rubber material used to form the tire is under high temperature and high pressure conditions. At this time, a part of the raw rubber that has not been vulcanized will be squeezed out through the vent holes onto the outer surface of the tire mold. These extruded rubber materials will form rubber hair on the tire tread. When the tire is removed, some of the rubber hair will break in the vent holes, thereby blocking the vent holes. In this way, the exhaust performance of the tire mold is affected in the subsequent production process. In order to ensure the quality of the final tire product, it is necessary to provide an additional process to remove the rubber hair formed on the tire. Therefore, the manufacturing process of the tire becomes complicated.

[0004] In order to avoid this situation, one solution is to arrange an exhaust device in the exhaust hole, for example, one form of the exhaust device is a pore sleeve, which is embedded in the exhaust hole. The structure of the pore sleeve is arranged to allow the air in the tire mold to be discharged, but when the rubber in the mold contacts the pore sleeve, the pressure of the rubber closes the pore sleeve, thereby preventing the rubber from being extruded through the pore sleeve to the surface of the tire mold.

[0005] Under existing technical conditions, the pore sleeve is manually inlaid on the tire mold, such as inlaying the pattern block or side plate of the tire mold. The quality of manual inlay varies from person to person, the technical experience of the operator is very high, and the efficiency of the inlay operation is relatively low.

[0006] Therefore, there is a need for a pore sleeve inlaying device capable of performing a pore sleeve inlaying operation, which can efficiently perform an automated operation of inlaying the pore sleeve. Summary of the invention

[0007] The present invention is made based on the above problems in the prior art. The purpose of the present invention is to provide an inlaying device that can efficiently perform the inlaying operation of the pore sleeve.

[0008] The present invention achieves the above-mentioned purpose through an inlay device. The inlay device is used to perform inlay operations on parts, and includes: an inlay part, which includes an inlay head, in which a punching hole is formed, in which parts can be accommodated, and the inlay part is also provided with a punching member, which is used to punch and push the parts in the punching hole; and a discharge part, which is connected to the inlay part, includes a head and a discharge end extending from the head, in which a first channel is formed, and the discharge part also includes a blocking member, which has a second channel connected to the first channel. The blocking member can be switched between a first state and a second state, in which, in the first state, the cross-sectional size of at least a part of the second channel is smaller than the cross-sectional size of the part, so as to prevent the part from passing through the second channel, and in the second state, the cross-sectional size of all parts of the second channel is equal to or larger than the cross-sectional size of the part, so as to allow the part to pass through the second channel.

[0009] The structure of the inlay device can realize automatic inlay of parts and improve the inlay efficiency.

[0010] In a specific structure, the blocking member includes a blocking member base and a clamping portion connected to the blocking member base, the second channel is formed in the clamping portion, and the clamping portion is elastically deformable so as to be switchable between a first state and a second state.

[0011] Furthermore, the clamping portion may specifically be composed of at least two elastic plates.

[0012] Preferably, a through hole extending from the outer peripheral surface to the first channel is formed in the head, and a force-applying assembly is arranged in the through hole, which applies a force on the clamping portion to bias the clamping portion in the first state. Through the bias of the force-applying assembly, the blocking member, especially the clamping portion thereof, can be more reliably maintained in the first state.

[0013] In a specific structure, the force-applying assembly includes: a force-applying block, which abuts against the clamping portion; a force-applying elastic member, which is connected to the force-applying block and applies elastic force on the force-applying block; and a clamping force adjusting member, which is adjustably inserted into the through hole and abuts against the force-applying elastic member. The force-applying elastic member can be, for example, an elastic member such as a spring. Moreover, the force-applying block, the force-applying elastic member, and the clamping force adjusting member are all optional components.

[0014] Preferably, a part detection device is provided on the discharge portion to detect whether there is a part in the second channel. Specifically, the detection device may include a light sensor, and a light-transmitting hole is provided on the clamping portion mentioned above, and the light sensor is aligned with the light-transmitting hole. Thus, the light sensor determines whether there is a part in the second channel by detecting whether light passes through the light-transmitting hole.

[0015] In a specific structure, a driving device is also connected to the embedded part, and the driving device is connected to the punching member to drive the punching member to reciprocate in the punching hole. In this way, the punching member can enter or leave the punching hole. A specific embodiment of the driving device is a cylinder. In addition, the driving device can also take other forms, such as an electric driving device, a hydraulic driving device, a magnetic driving device, etc.

[0016] Preferably, the embedding part is connected to the driving device in a relatively movable manner, and an elastic member is provided between the embedding part and the driving device, and the elastic member biases the embedding device in a direction away from the driving device. Thus, the embedding device, specifically the discharge end of the embedding device, can be judged by the relative position between the embedding part and the driving device to determine whether the embedding device, specifically the discharge end of the embedding device, is in contact with the embedding object such as a mold in which the part is to be embedded. A specific implementation of the elastic member is, for example, a spring.

[0017] Furthermore, a detection switch is also provided on the inlay part, and the detection switch detects the position of the inlay head relative to the driving device to determine whether the discharging end of the inlay device is in contact with the inlay object.

[0018] Preferably, the inlay device is also connected with a feed pipe, which is at least connected to the second channel. The provision of the feed pipe can facilitate the delivery of parts to the inlay device for inlaying. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The specific embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the drawings only show preferred embodiments of the present invention and do not limit the scope of the present invention. Those skilled in the art can make various obvious modifications, variations, and equivalent substitutions to the present invention based on the embodiments shown in the drawings, and the technical features in the described embodiments can be combined arbitrarily without contradiction, and all of these fall within the scope of protection of the present invention.

[0029] In the disclosure of the present invention, the terms "upper", "lower" and the like used to indicate direction or orientation are based on the orientation of the device when in use.

[0030] Figure 1 The inlay device 10 of the present invention is shown in a three-dimensional view. As shown in the figure, the inlay device 10 generally includes a discharge part 100 and an inlay part 200. Parts such as pore sleeves are fed into the discharge part 100, and then the inlay part 200 acts on the parts in the discharge part 100, such as pushing the parts out of the discharge part 100 and inlaying the parts into appropriate positions, such as inlaying the pore sleeves into holes that have been drilled on pattern blocks such as side panels and steel rims of tire molds.

[0031] <Discharging part>

[0032] Figure 2 A cross-sectional view of the discharge portion 100 of the setting device 10 as viewed from one side is shown, Figure 3 It shows Figure 2 FIG. 1 is a cross-sectional view of the discharge portion 100 viewed from the other side.

[0033] As shown in the figure, the discharge portion 100 includes a discharge end 110, which extends downward from a head 111 of the discharge portion 100. A through passage 112 extending from the head 111 to the bottom end of the discharge end 110 is formed in the discharge portion 100. Parts can pass through the through passage to reach the inlay position.

[0034] A blocking member 120 is disposed on the head 111 , which serves to temporarily block the parts from moving downward and leaving the discharge end 110 . Figure 4FIG. 1 shows an enlarged perspective view of the blocking member 120, thereby showing the structure of the blocking member 120 in detail. Figure 2 and Figure 4 The structure and action principle of the blocking member 120 will be described below.

[0035] The blocking member 120 includes a blocking member base 121 and a clamping portion, wherein the clamping portion is connected to the blocking member base 121 and includes a channel 123 for the parts to pass through. The blocking member 120 is fixed to the discharge portion 100 through the blocking member base 121. Figure 2 As shown in FIG. 1 , the blocking member base 121 is supported in a recess on the head 111 of the discharge end 110 , while the clamping portion extends into the through passage 112 of the discharge end 110 .

[0036] The clamping portion is preferably elastic so that it can be switched between a first state and a second state. In the first state, the cross-sectional diameter of at least a portion of the channel 123 in the clamping portion is smaller than the diameter of the part, so that the part can be clamped in the channel 123 of the clamping portion and the downward movement of the part is prevented, while in the second state, the clamping portion is elastically deformed so that the cross-sectional diameter of all portions of its channel 123 is equal to or larger than the diameter of the part, so that the part is allowed to move downward.

[0037] In the exemplary structure shown in the figure, the clamping portion includes two elastic plates 122 arranged opposite to each other, and the elastic plates 122 are formed by cutting the wall of the cylindrical portion, and the cutting slits used to form the elastic plates 122 can be formed opposite to each other. It can be known that the clamping portion can also be formed with more than two elastic plates 122 according to actual application occasions and needs, which is also within the scope of the present invention.

[0038] Preferably, the elastic plate 122 can gradually shrink toward its axial center, so that the cross-sectional diameter of at least the bottom of the clamping portion is smaller than the diameter of the part, so as to prevent the part from moving downward. Of course, the minimum diameter of the clamping portion does not have to be at the bottom, but can also be at other parts of the clamping portion, such as at the longitudinal middle position of the clamping portion.

[0039] The elastic plates 122 are biased toward each other by their own elasticity, whereby the clamping portion is biased in its first state. Alternatively, the elastic plates 122 may be biased and maintained in the first state under the action of an external force. For example, Figure 2 As shown in the figure, a through hole extending from the outer peripheral surface to the channel 112 is formed in the head 111 of the discharge part 100 of the embedding device 10, and a force block 131 is arranged in the through hole. The force block 131 abuts against the elastic plate 122 of the blocking member 120, so that the elastic plates 122 are close to each other and maintained in the first state.

[0040] In addition, a clamping force adjusting member 133 and a force-applying elastic member 132 (e.g., a coil spring) located between the force-applying block 131 and the clamping force adjusting member 133 are provided. The clamping force adjusting member 133 is, for example, a set screw that is adjustably inserted into the through hole through a threaded connection. By screwing in and out the set screw, the elastic force applied by the force-applying elastic member 132 can be adjusted, thereby adjusting the clamping force applied by the force-applying block 131 on the elastic plate 122.

[0041] The force applying block 131, the force applying elastic member 132 and the clamping force adjusting member 133 constitute a force applying assembly 130 for adjusting the clamping force applied to the elastic plate 122. The number of the force applying assemblies 130 may correspond to the number of the elastic plates 122 of the blocking member 120. Figure 2 and 3 In the case where two elastic plates 122 are included as shown in FIG, two force applying components 130 corresponding to the two elastic plates 122 respectively may be provided.

[0042] Preferably, the interior of the channel 123 of the clamping portion is smooth, thereby reducing the risk of the parts being scratched when the parts pass through the channel 123, and also reducing the friction force of the parts in the process of passing through the channel 123, thereby improving the embedding efficiency.

[0043] Preferably, a light-transmitting hole 124 is provided at the upper portion of the clamping portion of the blocking member 120. The diameter of the light-transmitting hole 124 is preferably greater than the width of the cutting seam between adjacent elastic plates 122. Corresponding to the light-transmitting hole 124, a detection switch 140 is provided. Figure 3 As shown. The detection switch 140 is, for example, a light sensor and is aligned with the light-transmitting hole 124. Thus, when there is a part in the passage of the blocking member 120, the detection switch 140 will detect that no light is transmitted through the light-transmitting hole 124, thereby providing a signal that there is a part in the passage of the blocking member 120. When the presence of the part is detected, the embedding part 200 to be described later can be controlled to perform an embedding action.

[0044] <Inlay part>

[0045] Figure 5 and 6 2 shows cross-sectional views of the inlay portion 200 viewed from different directions. Figure 5 and 6 As shown, the inlay part 200 includes a punching member 210 and an inlay head 220. A punching hole 222 is formed in the inlay head 220, and a punch rod of the punching member 210 can extend into the punching hole 222 to push the parts in the punching hole toward the discharge part 100 located below the inlay head 220.

[0046] The upper end of the punching and pushing member 210 is connected to the cylinder 230 , and the punching and pushing member 210 is driven by the cylinder 230 to punch and push the parts located in the punching and pushing hole 222 .

[0047] In addition, as shown in the figure, the setting device 10 of the present invention is also connected to a feed pipe 221, through which parts can be transported into the setting device 10 and enter the channel 123 of the blocking member 120. In other words, the feed pipe 221 should at least be connected to the channel 123. For example, in the structure shown in the figure, the feed pipe 221 is connected to the setting head 220 and communicates with the punching hole 222 of the setting head 220, so that parts from the upstream station can enter the punching hole 222, and then the parts can enter the channel 123 of the blocking member 120 through the punching hole 222, so as to be punched by the punch rod of the punching member 210 later.

[0048] A detection switch 240 is provided on the housing 250 of the inlaying part 200, and the detection switch 240 is located between the inlaying head 220 and the cylinder 230. In addition, an elastic member is also provided between the inlaying head 220 and the cylinder 230, and an exemplary embodiment of the elastic member is a spring 224 (see Figure 6 ), the spring 224 biases the setting head 220 in a direction away from the cylinder 230. Of course, the elastic member can also be implemented as other elastic structures that can achieve a biasing effect. The detection switch 240 is used to detect the position of the setting head 220 relative to the cylinder 230. The setting head 220 is preferably fixedly connected to the discharge part 100. In this way, when the detection switch 240 detects that the setting head 220 overcomes the elastic force of the spring 224 and moves upward toward the cylinder 230, it indicates that the discharge part 100 has contacted with a device to be set, such as a mold, and further indicates that the setting operation can be performed.

[0049] <Operation Principle>

[0050] The operating principle of the setting device 10 of the present invention will be described below.

[0051] When the detection switch 240 detects that the inserting head 220 overcomes the biasing force of the spring 224 and moves toward the cylinder 230, it indicates that the discharge part 100 is in contact with the mold to be inserted. If the detection switch 140 of the discharge part 100 also detects that the part to be inserted exists in the passage of the blocking member 120 at this time, the control device (not shown) can start the cylinder 230 to drive the punching member 210 to move downward, pass through the punching hole 222 of the inserting head 220 and enter the through channel 112 of the discharge part 100. In this process, the punching member 210 pushes the part to move downward.

[0052] Under the downward thrust of the punching member 210, the clamping portion expands from the first state to the second state, so that the part can be pushed out of the channel 123 of the clamping portion, and then move through the through channel 112, so as to be embedded in the required position.

[0053] Preferably, a punch rod limiter 223 is formed at the upper end of the punch hole 222 of the insert head 220, which is used to limit the downward punching stroke of the punch rod of the punching member 210. For example, in the structure shown in the figure, the punch rod limiter 223 is in the shape of a tapered hole, and correspondingly, the upper end of the punch rod is also tapered to match the tapered hole.

[0054] Figure 7 and 8 , a schematic cross-sectional view of the punch rod of the punching member 210 in an impact state is shown, from which it can be clearly seen that the punch rod extends through the punching hole 222 of the inserting head 220 and enters the through channel 112 of the discharge part 100, so that the part can be punched.

[0055] The structure and operation mode of the setting device 10 of the present invention are described in detail above. After reading the above disclosure, those skilled in the art can make obvious modifications and variations to the setting device 10 of the present invention without exceeding the scope of the present invention.

[0056] For example, in the specific embodiments described and illustrated above, the clamping portion clamps the parts in the form of at least two elastic plates 122. The clamping portion may also take other forms, such as a complete elastic tube, whose inner diameter is elastically variable under the action of force. Alternatively, the clamping portion may not be elastic, and its inner diameter is changed by the force-applying assembly 130.

[0057] On the other hand, in the case where the clamping portion is elastically deformable, the force applying assembly 130 is also optional. Alternatively, in the case where the force applying assembly 130 is included, 131, the clamping force adjusting member 133 and the clamping force adjusting member 133 in the force applying assembly 130 are also optional.

[0058] In the structure shown in the figure, the diameter of the light-transmitting hole 124 on the clamping portion of the blocking member 120 is larger than the width of the cut slit between the elastic plates 122. However, the size of the light-transmitting hole 124 may be equal to or smaller than the width of the cut slit, as long as it can allow light to pass through for detecting whether there is a part.

[0059] For another example, in the structure described and illustrated above, the punching member 210 is driven by the cylinder 230, but other forms of driving devices may also be used, such as hydraulic drive, electric drive, magnetic drive, etc.

[0060] The detection switch 240, spring 224 and other components in the embedding part 200 mentioned above, which are used to detect whether the discharge part 100 is in contact with the mold to be embedded, are also optional components.
