Description

Technical Field

[0001] This invention relates to a stacked mold labeling fixture, and more particularly to an automated stacked mold labeling fixture. Background Technology

[0002] Stacked molds combine multiple cavities into one mold, making full use of ordinary injection molding equipment to meet production needs. Their production efficiency is one or more times higher than that of ordinary single-layer molds, significantly reducing injection molding production costs. The application of in-mold labeling technology in stacked injection molding machines requires placing the printed and pressed film into the stacked mold cavity to integrate with the product to be labeled, achieving one-time completion of production and decoration.

[0003] Currently, to address the issues of complex structure, large footprint, and poor operational stability of in-mold labeling machines, a utility model patent with Chinese patent number "201721767840.6" proposes a stacked mold side-entry intelligent in-mold labeling system. This system includes a machine body, an external labeling supply component, an internal labeling delivery component, and an external material retrieval component. It employs a transfer and borrowing structure, dispersing the complex structure and simplifying the overall design. However, this structure only discloses the internal labeling delivery component for feeding the label paper received from the external labeling delivery component into the machine. The single function within the mold cavity is as follows: finished products removed from the in-mold labeling machine are transferred to the outside of the machine via an external picking component. Later, it is mentioned that a picking fixture extracts products from the punches on both sides of the central mold plate. However, the structural description does not clearly explain the specific structure of this suddenly appearing picking fixture or its connection and cooperation with other components, making it impossible to know how it works. The descriptions contradict each other. In the in-mold labeling component, the suspension part is fixed to the machine body, the sliding part is fixed to the suspension part, and the labeling fixture is slidably connected to the sliding part via a sliding seat. This structure has several drawbacks: First, the label feeding fixture is large and heavy. The top-down suspension method places a heavy load on the linear guide rail and slider, requiring high-performance structural materials. Furthermore, long-term use can lead to deformation and damage, posing safety hazards and necessitating repair or replacement, resulting in high overall operating costs. Second, each label feeding fixture is controlled by a separate sliding part, making it difficult to ensure synchronization between the two sides. This requires two sets of pulley drive devices, further increasing overall costs. Additionally, the subsequent operation of the external pick-up component adds extra waiting time, significantly increasing production time in large-scale mass production and reducing efficiency. Moreover, the specific structure and accompanying drawings of the external pick-up component do not clearly explain how the action of "rotating 90° to place the product on the conveyor belt" is achieved. This action is performed by the external pick-up component, which must wait for the product to be placed on the conveyor belt before rotating back to its original position to receive the next batch of products, increasing individual waiting time and contributing to low production efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automated stacking and labeling tooling that can work synchronously on both sides and has high production efficiency. The overall structure is reasonable, the space occupancy is low, and the overall assembly cost is relatively low.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: an automated stacking and labeling fixture, comprising a frame and a first label feeding mechanism, a second label feeding mechanism, a double-arm synchronous conveying mechanism, a double-sided synchronous receiving mechanism, a first flipping and picking mechanism, and a second flipping and picking mechanism respectively disposed on the frame. The bottom surface of the frame is provided with a feeding position, a picking position, and a discharging position sequentially from front to back. The double-arm synchronous conveying mechanism moves back and forth along the bottom surface of the frame between the feeding position and the picking position. A first suction conveying arm and a second suction conveying arm are respectively disposed on both sides of the double-arm synchronous conveying mechanism. The inner front end of the first suction conveying arm is used for conveying the double-arm synchronous conveyor by a first suction conveying fixture. When the mechanism moves to the feeding position, it adsorbs the first labeled product in the first mold cavity of the external stacked injection molding machine. The inner front end of the second adsorption conveying arm is used to adsorb the second labeled product in the second mold cavity of the external stacked injection molding machine when the double-arm synchronous conveying mechanism moves to the feeding position via the second adsorption conveying fixture. The first label supply mechanism and the second label supply mechanism are respectively fixedly installed on the frame on both sides of the material picking position. The outer front end of the first adsorption conveying arm is used to adsorb the first label paper provided by the first label supply mechanism at the material picking position via the first label suction fixture. The outer front end of the second adsorption conveying arm is used to adsorb the second label paper provided by the second label supply mechanism at the material picking position via the second label suction fixture. The dual-sided synchronous receiving mechanism moves back and forth along the top of the frame between the material receiving position and the material unloading position. The dual-sided synchronous receiving mechanism is provided with a first receiving and adsorption mechanism and a second receiving and adsorption mechanism on both sides. The first receiving and adsorption mechanism is used to adsorb and remove the first labeled product from the inner front end of the first adsorption conveying arm at the material receiving position. The second receiving and adsorption mechanism is used to adsorb and remove the second labeled product from the inner front end of the second adsorption conveying arm at the material receiving position. The first flipping and picking mechanism is used to pick up the first labeled product from the first receiving and adsorption mechanism at the unloading position and flip it to place it on the outer conveyor belt. The second flipping and picking mechanism is used to pick up the second labeled product from the second receiving and adsorption mechanism at the unloading position and flip it to place it on the outer conveyor belt.

[0006] The dual-arm synchronous conveying mechanism includes a movable base, a bottom pulley drive mechanism, a bottom slide rail slider guide mechanism, and a bottom movable connecting seat. The movable base is fixedly mounted on the bottom surface of the frame in the front-to-back direction. The bottom movable connecting seat is laterally mounted on the movable base in the left-to-right direction. The bottom pulley drive mechanism is located between the movable base and the bottom movable connecting seat. The bottom pulley drive mechanism drives the bottom movable connecting seat to move in the front-to-back direction of the movable base through the sliding guidance of the bottom slide rail slider guide mechanism. The first adsorption conveying arm is vertically fixed on one side of the bottom movable connecting seat and extends forward as a whole. The second adsorption conveying arm is vertically fixed on the other side of the bottom movable connecting seat and extends forward as a whole. In this structure, the weight of the upper part of the device is borne by the movable base, which can be composed of a main load-bearing beam and load-bearing columns located at the bottom front and rear of the main load-bearing beam. It can withstand greater pressure, increase the stability and safety of the structure, and has a long service life. The first and second adsorption conveying arms are respectively fixed on both sides of the bottom movable connecting seat, enabling them to move synchronously, thereby improving synchronization and increasing production efficiency.

[0007] The first adsorption conveying arm has a first fixed connecting frame at its front end. The upper and lower outer parts of the first fixed connecting frame are respectively equipped with the first label-absorbing fixture. A first label-applying displacement driving assembly is provided between the first label-absorbing fixture and the first fixed connecting frame. The upper and lower inner parts of the first fixed connecting frame are respectively equipped with the first adsorption conveying fixture. A first conveying displacement driving assembly is provided between the first adsorption conveying fixture and the first fixed connecting frame. The second adsorption conveying arm has a second fixed connecting frame at its front end. The upper and lower outer parts of the second fixed connecting frame are respectively equipped with the second label-absorbing fixture. A second label-applying displacement driving assembly is provided between the second label-absorbing fixture and the second fixed connecting frame. The upper and lower inner parts of the second fixed connecting frame are respectively equipped with the second adsorption conveying fixture. A second conveying displacement driving assembly is provided between the second adsorption conveying fixture and the second fixed connecting frame. The structure is clear and reasonable, making full use of limited space, and the components on both sides work independently without interfering with each other.

[0008] The first label suction fixture includes a first suction-type labeling phantom and a first labeling phantom substrate for suction-adsorbing and mounting the first label paper. The first labeling displacement driving assembly includes a first labeling cylinder mounting plate, a first labeling cylinder, and a first labeling driving plate. The first labeling cylinder mounting plate is horizontally fixedly disposed at the upper or lower end of the first fixed connecting frame. The first labeling cylinder is fixedly disposed outwardly on the first labeling cylinder mounting plate. The top end of the output shaft of the first labeling cylinder is fixedly connected to the first labeling driving plate. The first labeling phantom substrate is vertically fixedly disposed on the outside of the first labeling driving plate. The first suction-type labeling phantom is fixedly disposed on the outside of the first labeling phantom substrate. The first adsorption and conveying fixture includes a first conveying suction block with a first conveying suction head and a first conveying pressure plate. The first conveying displacement driving assembly includes a first conveying cylinder mounting plate, a first conveying cylinder, a first conveying drive plate, and a first conveying fixture plate. The front end of the middle part of the first fixed connecting frame is recessed to form a first mounting groove. The first conveying cylinder mounting plate is vertically fixed at the bottom of the first mounting groove. The first conveying cylinder is horizontally fixed inward on the first conveying cylinder mounting plate. The first conveying fixture plate is vertically fixedly connected to the output shaft of the first conveying cylinder through the first conveying drive plate. The first conveying suction block is fixedly installed on the upper inner side or lower inner side of the first conveying fixture plate and is at the same horizontal height as the first labeling cylinder. The first conveying pressure plate is vertically fixed inside the first conveying suction block. A first conveying suction hole is opened in the first conveying pressure plate, and the first conveying suction head passes inward through the first conveying suction hole. The first conveying cylinder mounting plate is vertically fixed at the bottom of the first mounting groove. The setting of the first conveying fixture plate ensures that the position of the first conveying pressure plate and the position of the first adsorption labeling phantom are at the same height and the front and rear positions are also corresponding. The structural design is ingenious. The design of the first mounting groove can save materials, reduce some weight, thereby reducing the load pressure at the bottom and increasing the safety of use.

[0009] The first label feeding mechanism includes a label storage rack, an upper label cavity base plate, a lower label cavity base plate, an upper rotating label suction mechanism, and a lower rotating label suction mechanism. The label storage rack is vertically fixed to one side of the frame. The upper label cavity base plate and the lower label cavity base plate are respectively fixedly mounted on the label storage rack from top to bottom. An upper label cavity assembly for storing the first label paper is fixedly mounted on the outer side of the upper label cavity base plate, and a lower label cavity assembly for storing the first label paper is fixedly mounted on the outer side of the lower label cavity base plate. The upper label cavity base plate has an upper label cavity that matches the shape of the first label paper. The label dispensing hole is provided on the lower label cavity substrate, which has a lower label dispensing hole that matches the shape of the first label paper. The upper rotating label suction mechanism and the lower rotating label suction mechanism are respectively fixedly arranged on the inner side of the label storage mounting frame from top to bottom. The upper rotating label suction mechanism is used to pick up the first label paper from the upper label cavity assembly and rotate it inward to correspond to the horizontal position of the first label suction fixture located at the top. The lower rotating label suction mechanism is used to pick up the first label paper from the lower label cavity assembly and rotate it inward to correspond to the horizontal position of the first label suction fixture located at the bottom.

[0010] The aforementioned upper rotating label-absorbing mechanism includes a mounting base, a rotating cylinder, a rotating connecting frame, a rotating seat with a rotating hole, a telescopic label-carrying cylinder, and a label-absorbing block for absorbing the first label. The mounting base is fixedly installed on the front side of the upper inner part of the label storage mounting frame. The rotating cylinder is horizontally fixedly installed on the mounting base. A front rotating shaft is fixedly installed forward at the front end of the rotating connecting frame. The output shaft of the rotating cylinder is fixedly coaxially connected to the front rotating shaft via a coupling. A rear rotating shaft is fixedly installed rearward at the rear end of the rotating connecting frame. The rotating seat is fixedly installed on the rear side of the upper inner part of the label storage mounting frame. The end of the rear rotating shaft is rotatably installed in the rotating hole. The telescopic label-carrying cylinder is fixedly installed in the middle of the rotating connecting frame along the inward and outward direction. The label-absorbing block is fixedly installed at the end of the output shaft of the telescopic label-carrying cylinder. The label-absorbing block corresponds to the horizontal position of the first label-absorbing fixture located at the top. This structure allows the telescopic label-carrying cylinder to be installed on a relatively stable horizontal carrier, making its operation more stable and less prone to shaking, thereby improving the reliability of label alignment during the labeling process.

[0011] The dual-sided synchronous receiving mechanism includes a receiving displacement main shaft, a top pulley drive mechanism, a top slide rail slider guide mechanism, and a top movable connecting seat. The receiving displacement main shaft is fixedly installed on the top of the frame from front to back. The top pulley drive mechanism is fixedly installed inside the receiving displacement main shaft. The top pulley drive mechanism drives the top movable connecting seat to move along the bottom of the receiving displacement main shaft in a front-back direction through the sliding guidance of the top slide rail slider guide mechanism. A receiving connecting arm extends rearward from the bottom of the top movable connecting seat. The first receiving adsorption mechanism is fixedly connected to the top of the receiving connecting arm and located on one side of the receiving connecting arm. The second receiving adsorption mechanism is fixedly connected to the bottom of the receiving connecting arm and located on the other side of the receiving connecting arm. By making full use of the space at the top of the frame, the overall volume of the dual-sided synchronous receiving mechanism is relatively small. Therefore, designing it to move along the upper part of the frame is reasonable and does not affect safety.

[0012] The first receiving and adsorption mechanism includes a first receiving cylinder fixing plate, a first receiving cylinder, a first receiving base plate, a receiving variable pitch cylinder, a first upper receiving mounting plate, a first upper receiving adsorption head, a first lower receiving mounting plate, and a first lower receiving adsorption head. The first receiving cylinder fixing plate is fixedly mounted on the top of the receiving connecting arm. The first receiving cylinder is horizontally fixed outward on the first receiving cylinder fixing plate. The first receiving base plate is vertically fixed at the end of the output shaft of the first receiving cylinder. The first upper receiving mounting plate and the first receiving base plate... A receiving slide rail slider guide mechanism is provided between the components. The receiving variable pitch cylinder is vertically fixed on the first receiving base plate. The receiving variable pitch cylinder is used to drive the first upper receiving mounting plate to move up and down on the upper part of the first receiving base plate through the receiving slide rail slider guide mechanism. The first upper receiving suction head is fixedly extended outward on the first upper receiving mounting plate, and the first lower receiving mounting plate is fixedly installed at the lower part of the first receiving base plate. The first lower receiving suction head is fixedly extended outward on the first lower receiving mounting plate. The structure is simple. The purpose of setting the receiving variable pitch cylinder is to adapt to the different product spacing requirements in the mold cavity of the stacked injection molding machine in subsequent processing steps, thereby adaptively adjusting the spacing between the upper and lower products without manual adjustment, improving the overall automation level.

[0013] The first flipping and picking mechanism includes a flipping mounting frame, a flipping sliding base plate, a flipping belt pulley drive mechanism, a flipping slide rail slider guide mechanism, a flipping connecting arm, a 90-degree flipping cylinder, a flipping connecting frame, a flipping telescopic cylinder, a flipping fixture plate, an upper flipping and picking fixture, and a lower flipping and picking fixture. The flipping mounting frame is vertically fixed at the unloading position of the machine frame. The flipping sliding base plate is slidably mounted on the flipping mounting frame in the vertical direction via the flipping slide rail slider guide mechanism. The flipping belt pulley drive mechanism is used to drive the flipping sliding base plate to slide up and down. The flipping connecting arm is vertically and horizontally fixed to the flipping sliding base plate. Above, the 90-degree tilting cylinder is vertically and fixedly mounted on the tilting connecting arm, the tilting connecting frame is fixedly mounted on the tilting plate of the 90-degree tilting cylinder, the tilting telescopic cylinder is fixedly mounted on the tilting connecting frame, the 90-degree tilting cylinder drives the tilting telescopic cylinder to tilt between horizontal and vertical angles through the tilting connecting frame, the tilting fixture plate is vertically and fixedly connected to the output shaft of the tilting telescopic cylinder, the upper tilting part-retrieving fixture is fixedly mounted on the upper part of the tilting fixture plate in the vertical state, and the lower tilting part-retrieving fixture is fixedly mounted on the lower part of the tilting fixture plate in the vertical state. The product received by one side of the dual-sided synchronous receiving mechanism is handed over to the upper and lower flip-up jigs for receiving. Then, the 90-degree flip cylinder drives the flip jig plate from the vertical state to the horizontal state through the flip connecting frame. Subsequently, the flip pulley drive mechanism drives the flip sliding base plate to slide downward until the upper and lower flip-up jigs place the product on the external conveyor belt. Then, each component moves upward and flips back to its original position, waiting for the next round of operation.

[0014] Compared with the prior art, the advantages of this invention are that it realizes the transportation of the label paper of the external stacked injection molding machine and the handling of the labeled products through the double-arm synchronous conveyor mechanism. First, the labeled products are transported to the unloading position by the double-sided synchronous receiving mechanism. Then, the first flipping and picking mechanism and the second flipping and picking mechanism respectively transfer the corresponding labeled products and flip them down onto the external conveyor belt. The working efficiency is high, the overall structure layout is reasonable, the processing and manufacturing are convenient, the overall space occupation is low, and the overall cost is relatively low. In particular, the double-arm synchronous conveyor mechanism moves back and forth along the bottom of the frame between the feeding position and the picking position, and the weight of the upper part of the structure is borne by the bottom. The load-bearing capacity is relatively safe and reliable. The double-arm synchronous conveying mechanism is equipped with a first adsorption conveying arm and a second adsorption conveying arm on each side. All structures on both sides move synchronously as a whole, with high overall synchronicity. For mass production processes, this can greatly reduce waiting time and thus improve production efficiency. The products received on both sides of the double-sided synchronous receiving mechanism are transferred and lowered by two flipping and picking mechanisms. This ensures that there is no obstruction or conflict between the various structures during flipping. After the transfer, the double-sided synchronous receiving mechanism can continue to move to the picking position to wait for the next batch of products without waiting for the products to be lowered, further improving production efficiency.

[0018] The first adsorption and conveying fixture includes a first conveying suction block 42 with a first conveying suction head 41 and a first conveying pressure plate 43. The first conveying displacement driving assembly includes a first conveying cylinder mounting plate 44, a first conveying cylinder 45, a first conveying drive plate 46, and a first conveying fixture plate 47.

The second suction conveying fixture has the same structural principle as the first suction conveying fixture, but is adapted to the structure of the second labeling product.

[0019] The specific working process of the above embodiments is as follows: Step 1: The dual-arm synchronous conveying mechanism 14 moves along the bottom surface of the frame 11 to the material feeding position. The outer front end of the first suction conveying arm 21 absorbs the first label paper provided by the first label feeding mechanism 12 at the material feeding position through the first label suction fixture. The outer front end of the second suction conveying arm 22 absorbs the second label paper provided by the second label feeding mechanism 13 at the material feeding position through the second label suction fixture. Subsequently, after the external stacked injection molding machine opens the mold, the dual-arm synchronous conveying mechanism 14 moves along the bottom surface of the frame 11 to the feeding position. Driven by the first labeling cylinder 34, the first label suction fixture feeds the first label paper into the first label feeding position of the external stacked injection molding machine. Inside the concave mold of the first mold cavity, the first suction and conveying fixture, driven by the first conveying cylinder 45, removes the first labeled product that has been labeled from the convex mold in the first mold cavity. At the same time, the second suction label fixture, driven by the second labeling cylinder 34, feeds the second label into the concave mold of the second mold cavity of the external stacked injection molding machine. The second suction and conveying fixture, driven by the second conveying cylinder 45, removes the second labeled product that has been labeled from the convex mold in the second mold cavity. Subsequently, each component retracts and resets, and the double-arm synchronous conveying mechanism 14 moves along the bottom surface of the frame 11 to the material picking position. Step 2: The first receiving and adsorption mechanism adsorbs and removes the first labeled product from the inner front end of the first adsorption conveying arm 21 at the material picking position, while the second receiving and adsorption mechanism adsorbs and removes the second labeled product from the inner front end of the second adsorption conveying arm 22 at the material picking position. The dual-arm synchronous conveying mechanism 14 moves along the bottom surface of the frame 11 to the unloading position. Step 3: The first flipping and picking mechanism 16 picks up the first labeled product from the first receiving and adsorption mechanism at the unloading position and flips it to place it on the outer conveyor belt 18. At the same time, the second flipping and picking mechanism 17 picks up the second labeled product from the second receiving and adsorption mechanism at the unloading position and flips it to place it on the outer conveyor belt 18, thus completing one round of labeling and picking process.

The label storage mounting frame 51 is vertically fixed on one side of the frame 11. The upper label cavity substrate 52 and the lower label cavity substrate 53 are respectively fixed on the label storage mounting frame 51 from top to bottom. An upper label cavity assembly 521 for storing the first label is fixedly provided on the outer side of the upper label cavity substrate 52, and a lower label cavity assembly 531 for storing the first label is fixedly provided on the outer side of the lower label cavity substrate 53.
