In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0063] See also Figures 1 to 11 The present invention provides a packaging device for hot buns, which is used to automatically and intelligently produce and assemble various hot bun products. For ease of understanding, in the following embodiments, the packaging device for hot buns is described as having a substantially vertical vertical direction and a horizontal plane. The vertical direction is substantially the direction of gravity, which has an upward direction and a downward direction. The horizontal plane has multiple horizontal directions. The horizontal direction and the longitudinal direction are two substantially vertical horizontal directions on the horizontal plane.

[0064] Specifically, the packaging equipment of the hot pack includes a collective, a feeding module, an inner bag packaging module, a transfer module and an outer bag packaging module.

[0065] The machine body defines a first operating position and a second operating position spaced apart in a transverse direction, a first intermediate transfer position located below the first operating position, and a second intermediate transfer position located below the second operating position.

[0066] The feeding module is arranged above the first operating position, and is used for quantitatively conveying medicinal materials to the first operating position.

[0067] The inner bag packaging module is used to provide an inner bag to the first operating position, and to package the medicinal materials transported to the first operating position into the inner bag to form a hot-packed semi-finished product.

[0068] The transfer module includes a rotating device and a picking device. The rotating device is used to transfer the hot-rolled semi-finished product to the second transfer position after the hot-rolled semi-finished product falls from the first operating position to the first transfer position. The picking device is used to pick up the hot-rolled semi-finished product at the second transfer position and bring it to the second operating position.

[0069] The outer bag packaging module is used to provide an outer bag to the second operating position, and to package the hot-pack semi-finished product delivered to the second operating position into the outer bag to form a hot-pack finished product.

[0070] In the technical solution provided by the present invention, the machine body integrates the feeding module, the inner bag packaging module, the transfer module and the outer bag packaging module into a whole, so that the intelligent and automatic operation of the entire packaging process from medicinal materials to hot-packed finished products can be realized. The feeding module quantitatively transports medicinal materials to ensure that the category and quality of medicinal materials in each hot-pack remain consistent; the transfer module can be adapted to the different arrangement orientations of the inner bag packaging module and the outer bag packaging module to ensure the smooth and fast transfer of materials (that is, the hot-packed semi-finished products) from the inner bag packaging module to the outer bag packaging module, and ensure that the inner bag packaging module performs inner bag packaging on the medicinal materials, and after obtaining the hot-packed semi-finished products, the outer bag packaging module performs outer bag packaging on the hot-packed semi-finished products, and obtains the hot-packed finished products. This operation process is smoothly connected, so that the whole machine is more flexible and universal for the packaging of hot-packed equipment, the operation is more intelligent and automated, and the products are more high-quality and efficient.

[0071] In the present design, the machine body is used to integrate the feeding module, the inner bag packaging module, the transfer module and the outer bag packaging module into a whole. However, it is understandable that the machine body can be composed of one or at least two structural members. The structural member can be, but is not limited to, a plate, a pipe, a block, a frame and other structures. In addition, the machine body can fix the feeding module, the inner bag packaging module, the transfer module and the outer bag packaging module together. Or the machine body includes multiple bases. A base can be provided for supporting and installing at least one of the feeding module, the inner bag packaging module, the transfer module and the outer bag packaging module.

[0072] For example Figures 1 to 11In the structure shown, the machine body may specifically include a first base, a second base and a third base. The first base may be used to support and install the feeding module and the inner bag packaging module, so that the whole formed by the feeding module and the inner bag packaging module can be arbitrarily loaded into or removed from the whole hot pack packaging equipment according to actual needs. The second base may be used to support and install the transfer module, so that the transfer module can be arbitrarily loaded into or removed from the whole hot pack packaging equipment according to actual needs. The third base may be used to support and install the outer bag packaging module, so that the outer bag packaging module can be arbitrarily loaded into or removed from the whole hot pack packaging equipment according to actual needs.

[0073] Please combine the specific Figures 1 to 6 In one embodiment, the loading module includes a storage hopper, a discharge hopper, a vacuum generator and a discharge pipe.

[0074] The storage hopper can be opened and closed, and is used to receive medicinal materials when it is opened. It can be understood that a storage cavity is formed inside the storage hopper. At least one end of the storage cavity forms an opening. The opening can be opened and closed by, for example, a cover structure. When the opening is opened, external medicinal materials can be transferred to the storage cavity with the help of a manipulator, a transmission device, etc. When the opening is closed, the storage cavity can be enclosed to create a relatively safe and hygienic storage space for the medicinal materials.

[0075] According to actual needs, an identifier such as a barcode scanner can be placed outside the storage hopper. The identifier is electrically connected to the power member that drives the cover body to move through the control device. In this way, when the identifier confirms that the type and quantity of the medicinal materials currently required to be added meet the requirements through identification, the cover body can be controlled to open. Otherwise, it cannot be opened. This helps to ensure the accuracy of the medicinal materials.

[0076] The storage hopper may be integrated with a processing device for performing appropriate and necessary processing on the medicinal materials. The processing device may be, but is not limited to, a drying device, a sterilizing device, a turning device, etc. This ensures that the medicinal materials can be processed in time in the storage hopper before being packaged into hot packs.

[0077] The discharge hopper is connected to the lower part of the storage hopper. The inlet end of the discharge hopper and the outlet end of the storage hopper are connected in a disconnectable manner. The discharge hopper is generally designed to be funnel-shaped from top to bottom so as to better concentrate the output of the medicinal materials.

[0078] The vacuum generator is arranged at the storage hopper and / or the discharging hopper to generate negative pressure in the storage hopper and / or the discharging hopper, and the negative pressure transfers the medicinal materials from the outside to the storage hopper and / or transfers the medicinal materials from the storage hopper to the discharging hopper. The vacuum generator is, for example, a vacuum pump. The vacuum pump can realize the transfer of medicinal materials between the storage hopper and the discharging hopper by generating vacuum suction force, and will not have a negative impact on the quality of the medicinal materials.

[0079] The discharge pipe is arranged to penetrate in the vertical direction, and the inlet end of the discharge pipe is connected to the lower part of the outlet end of the discharge hopper and is located above the first operating position. The specific shape of the discharge pipe is not limited, and can be but not limited to the following: Figure 4 The straight pipe shape shown. The discharge pipe is mainly used to guide the medicinal materials at the outlet end of the discharge hopper to the first operating position. It can avoid the medicinal materials being scattered during the transfer process due to the distance between the discharge hopper and the first operating position being too far, resulting in waste. On the contrary, it can also avoid the discharge hopper and the first operating position being too close, occupying too much space, making it difficult for other related components to be installed nearby.

[0080] The quantitative feeding screw is installed in the discharge hopper rotatably and translationally around its own axis, so that during the feeding process, the medicinal materials in the discharge hopper are quantitatively transported to the discharge pipe. Specifically, at least the discharge section of the discharge hopper is formed with an internal thread, and the internal thread is adapted to the external thread of the quantitative feeding screw, so that during the quantitative feeding screw feeding along the discharge section thread of the discharge hopper, the medicinal materials at the discharge hopper can be quantitatively output to the discharge pipe. By controlling the start and stop of the feeding process of the quantitative feeding screw, the medicinal materials at the discharge hopper can also be output to the discharge pipe at a regular time to adapt to the different packaging rhythms of the hot pack packaging equipment.

[0081] The storage hopper, discharge hopper and discharge pipe mentioned above can be integrally formed or separately formed according to actual needs. Any one or at least two of the storage hopper, discharge hopper and discharge pipe can be flexibly adjusted in number, position, etc. according to actual needs. In addition, the storage hopper, discharge hopper and discharge pipe can be fixedly connected in a fixed position. Alternatively, the storage hopper, discharge hopper and discharge pipe can be flexibly connected in a flexible position, so that the loading module is more versatile and practical.

[0082] Then please combine Figures 3 to 6 In one embodiment, the inner bag packaging module includes a first film supply assembly, a guide cone, a first sealer, two extrusion wheel assemblies and a first cutter.

[0083] The first film supply assembly is arranged on one lateral side of the discharge pipe, and includes a plurality of first material rollers, which are used to place the first film roll, and during its rotation, the first film material of the first film roll is horizontally unfolded and released laterally. The number of first material rollers in the first film supply assembly, the arrangement orientation, etc., can be adjusted according to actual needs. The first film supply assembly is generally arranged on one lateral side of the first base. And the rotation of the first material roller needs to be driven by a special power component. When at least one first material roller is actively rotated, the remaining first material rollers can be driven to rotate passively, thereby realizing the continuous release of the first film roll. Of course, at least one of the first material rollers can also be set as a spare material roller. That is, the spare material roller can be pre-placed with at least one first film roll automatically or manually by a manipulator. Thereby avoiding a long waiting time for the first film supply assembly.

[0084] The first film material of the first film roll is unfolded from one lateral side of the first base approximately along the horizontal plane toward the other lateral side of the first base and continuously fed out. The guide cone is sleeved on the outside of the discharge pipe in a conical shape, and the conical side wall of the guide cone is provided with an avoidance hole along its generatrix on the side facing away from the first material roller. After the horizontally unfolded first film material is bent and deformed around the conical side wall of the guide cone, the longitudinal sides of the first film material are close to each other and gathered at the avoidance hole, thereby finally forming an inner bag that passes through from top to bottom. The inner bag is sleeved on the outside of the discharge pipe.

[0085] In view of the above, it can be known that the longitudinal sides of the first film material are brought close to each other and then gathered to form an inner bag. At this time, the gathered part is still in a separated state, which is obviously not suitable for containing medicinal materials. At this time, the first sealer is arranged on the lateral side of the discharge pipe and is located below the avoidance hole. The first sealer is used to seal the side seam of the inner bag. The first sealer may include a hot press. The hot press corresponds to the side seam of the inner bag, that is, the above-mentioned gathered part. The hot press can connect and fix the side seam of the inner bag during its heating process. It should be noted that the specific type and specific structure of the first sealer can be specifically adjusted according to the material of the inner bag, that is, the material of the first film material. For example, when the first film material is a non-woven fabric, the first sealer can be designed to be more suitable for non-woven fabric sealing, such as an ultrasonic sealer, a hot pressure sealer, a sewing machine, etc.

[0086] While or after the side seams of the inner bag are sealed, two extrusion wheel groups are arranged below the guide cone and on both sides of the longitudinal direction of the discharge pipe. Each extrusion wheel group includes an extrusion roller rotatably arranged around a fixed axis. The wheel surface of the extrusion roller faces and rolls against the inner bag to drive the inner bag to be transported downward during its rotation. It can be understood that during the rotation of the extrusion roller, interference will be generated between the wheel surface of the extrusion roller and the inner bag. This interference can drive the inner bag to be transported downward. In addition, it should be noted that when the two extrusion wheel groups are movable and adjustable in the direction of approaching and moving away from each other in the longitudinal direction, the inner bag can be appropriately squeezed at the same time, so that the inner bag is squeezed and expanded from a flat shape, which is more suitable for receiving the medicinal materials discharged out of the discharge pipe.

[0087] The first cutter is arranged below the discharge pipe, and is used to cut and seal the upper and lower ends of the inner bag. Similarly to the above, the specific type and specific structure of the first cutter can be specifically adjusted according to the material of the inner bag, that is, the material of the first film material. For example, when the first film material is a non-woven fabric, the first cutter can be designed to be more suitable for non-woven fabric sealing, such as an ultrasonic cutter. Since the inner bags and medicinal materials are supplied continuously or intermittently. After the first cutter cuts and seals the upper end of the lowest inner bag, it can also cut and seal the lower end of the inner bag above the inner bag. In this way, before receiving the medicinal materials discharged outward through the discharge pipe, the side seams and the lower end of the inner bag can be sealed in place to ensure that the medicinal materials will not leak out.

[0088] It should be noted that the number and orientation of at least one of the first film supply assembly, the guide cone, the first sealer, the two extrusion wheel groups and the first cutter can be adjusted according to actual needs. In addition, at least one of the first film supply assembly, the guide cone, the first sealer, the two extrusion wheel groups and the first cutter can be fixedly connected relative to the first base so that the position remains unchanged. Or at least one of the first film supply assembly, the guide cone, the first sealer, the two extrusion wheel groups and the first cutter can be designed as a flexible connection with a flexible position adjustment relative to the first base, so as to enable translation adjustment, rotation adjustment, etc. in the horizontal, longitudinal and / or vertical directions.

[0089] Also see Figures 7 to 9 The rotating device includes a rotating member and a first driving mechanism. The rotating member is provided with at least two carriers at intervals and is rotatably installed on the second base around an axis extending in the up-down direction. Under the drive of the first driving mechanism, the rotating member rotates and drives each carrier to pass through the first transfer position and the second transfer position in sequence.

[0090] The picking device comprises a picking member and a second driving mechanism. The picking member is movably mounted on the second base in the up-down direction. Driven by the second driving mechanism, the picking member can reciprocate between the second transfer position and the second operating position.

[0091] The picking piece can also rotate around an axis extending vertically, and the picking device also includes a deflection mechanism. Driven by the deflection mechanism, the picking piece drives the position of the hot-packed semi-finished product to be adjustable.

[0092] Specifically, the second base may include a bottom frame and a side frame. The bottom frame extends substantially along the horizontal plane, which helps to be more firmly placed on the horizontal plane. The bottom frame may be in the form of a plate, a block, a frame, or other specific structures, for example Figures 7 to 9 As shown, the base frame is generally a frame structure and a plate-like structure partially arranged in the frame structure. The base frame can at least be installed with a rotating device. The side frame extends in the up-down direction and is arranged on one side of the base frame. Similar to the base frame, the side frame can be specifically expressed as a plate-like, block-like, frame-like structure. The side frame can be movably installed for the picking device to reserve enough space for the picking piece to move up and down.

[0093] In the rotating device, the specific structure of the rotating member is not limited, for example, it can be a disc structure, and sufficient space is reserved for more carriers to be installed. In order to make the structure simpler and more suitable for the production rhythm of the hot-rolled semi-finished product, in this embodiment, the rotating member is elongated to have a middle section and two edge sections connected to the two ends of the middle section. The middle section and the edge sections can be integrally formed, or they can be detachably or non-detachably connected after being separately formed. A carrier is detachably installed on each of the two edge sections, and the middle section is rotatably installed on the second base through a rotating shaft. In this way, the middle section and the two edge sections extend roughly along the radial direction of the rotating member in the rotating state; and the two carriers are arranged at both ends of the diameter of the rotating member. When one edge section drives one carrier to rotate and move to the first transfer position, the other edge section drives another carrier to rotate and move to the second transfer position. In this way, the first transfer position and the second transfer position can be spaced as far as possible, thereby reserving sufficient space for the mechanisms at the first operating position and the second operating position to operate.

[0094] There is no limitation on the connection method between the carrier and the edge segment, which can be an integral molding arrangement, or a detachable or non-detachable connection after separate molding. Figures 7 to 9As shown, the carrier includes a bottom plate, and two first side plates and two second side plates mounted on the bottom plate, and the bottom plate, the two first side plates and the two second side plates together enclose a groove for accommodating the semi-finished hot pot buns. Similarly to the above, the bottom plate, the two first side plates and the two second side plates can be integrally formed, or can be detachably or non-detachably connected after separate forming. Among them, the two first side plates roughly correspond to the thickness direction of the semi-finished hot pot buns, and the two second side plates roughly correspond to the width direction of the semi-finished hot pot buns. The two first side plates and / or the two second side plates are arranged away from each other from bottom to top. In this way, the groove can be formed into a shape in which the width of the lower groove section is small and the width of the upper groove section is large. The width of the upper groove section of the groove is relatively large, forming a flared mouth. On the one hand, it allows the semi-finished hot-am bag at the first operating position to fall more smoothly and unimpeded into the carrier at the first transfer position; on the other hand, it also allows enough space for the pick-up part to extend into the carrier at the second transfer position and perform a clamping operation on the semi-finished hot-am bag. The width of the lower groove section of the groove is relatively small, which helps to limit the semi-finished hot-am bag in the horizontal direction (that is, the thickness direction and / or width direction of the semi-finished hot-am bag). It can be understood that the medicinal materials in the semi-finished hot-am bag will be concentrated at the bottom of the semi-finished hot-am bag under the action of gravity, so that the center of gravity of the semi-finished hot-am bag is closer to its bottom. By limiting the hot-meal bag semi-finished product in the horizontal direction at the lower groove section of the groove, the state of the hot-meal bag semi-finished product as a whole can be locked, so that the hot-meal bag semi-finished product can be roughly maintained in a vertical state after falling into the carrier, and it is easier to maintain the vertical state when the rotating part drives the hot-meal bag semi-finished product to rotate from the first transfer position to the second transfer position, ultimately facilitating the smooth clamping of the hot-meal bag semi-finished product by the picking part.

[0095] The depth of the groove can be designed to be greater than, equal to or less than the length of the semi-finished hot-rolled bun according to actual needs. When the depth of the groove is less than the length of the semi-finished hot-rolled bun, the pick-up piece can directly clamp the portion of the semi-finished hot-rolled bun that extends out of the groove, but it is not conducive to limiting the position of the semi-finished hot-rolled bun. However, when the depth of the groove is greater than the length of the semi-finished hot-rolled bun, in order to facilitate the clamping of the pick-up piece, in one embodiment, the two first side plates are provided with avoidance recesses at corresponding positions, and the avoidance recesses are used to form avoidance when the pick-up piece moves close to each other, so that the pick-up piece can extend into the groove without contacting the first side plate and / or the second side plate. In this way, on the one hand, it helps to smoothly clamp the pick-up piece, and on the other hand, it avoids collisions between the pick-up piece and the carrier, which increases noise and may cause structural damage.

[0096] In order to make the first drive mechanism, the second drive mechanism, etc. move more continuously and smoothly, in a further solution, the transfer module also includes an in-position detection device, such as a photoelectric sensor. The in-position detection device includes two signal emitting parts, a first signal receiving part and a second signal receiving part, both of which are arranged in the middle section and are arranged toward the two edge sections respectively; the first signal receiving part is arranged on the second base and is located at a position of the first transfer position away from the middle section; the second signal receiving part is arranged on the second base and is located at a position of the second transfer position away from the middle section.

[0097] The in-position detection device, the first drive mechanism and the second drive mechanism are respectively used to be electrically connected to the control device; when the control device confirms that the first signal receiving part has not received the detection signal and the second signal receiving part has received the detection signal, the first drive mechanism is controlled to drive the rotating part to rotate; when the control device confirms that the first signal receiving part has received the detection signal and the second signal receiving part has not received the detection signal, the second drive mechanism is controlled to drive the picking part to transfer the hot pack semi-finished product from the second transfer position to the second operating position. The two signal emitting parts are arranged at the rotating part, so that during the rotation of the rotating part, the directions of the two signal emitting parts remain unchanged and always face the corresponding carrier.

[0098] Specifically, the first signal receiving part is fixedly arranged at the second base and is always facing the first transfer position. When a carrier rotates to the first transfer position, there is basically no obstruction between the corresponding signal emitting part and the first signal receiving part, and the detection signal emitted by the signal emitting part can be received by the first signal receiving part. It can be known that the current carrier is empty and no hot-rolled semi-finished product is loaded. At this time, the first driving mechanism maintains the rotating part in the current state. However, when the hot-rolled semi-finished product falls from the first operating position to the first transfer position, the signal emitting part and the first signal receiving part are blocked by the hot-rolled semi-finished product, and the detection signal emitted by the signal emitting part cannot be received by the first signal receiving part. It can be known that the current carrier has been loaded with the hot-rolled semi-finished product. At this time, the first driving mechanism can drive the rotating part to rotate and rotate the carrier loaded with the hot-rolled semi-finished product to the second transfer position.

[0099] Then, the second signal receiving part is fixedly arranged at the second base and always faces the second transfer position. Similarly to the above, when a carrier rotates to the second transfer position, there is basically no obstruction between the corresponding signal sending part and the second signal receiving part, and the detection signal sent by the signal sending part can be received by the second signal receiving part. It can be known that the current carrier is empty and no hot-rolled semi-finished product is loaded. At this time, the second driving mechanism maintains the picking part in the current unpicked state. However, when the carrier loaded with hot-rolled semi-finished products rotates from the first transfer position to the second transfer position, the signal sending part and the second signal receiving part are blocked by the hot-rolled semi-finished products, and the detection signal sent by the signal sending part cannot be received by the second signal receiving part. It can be known that there are hot-rolled semi-finished products at the current second transfer position. At this time, the second driving mechanism can drive the picking part to move close to the second transfer position, clamp the hot-rolled semi-finished products to detach from the carrier, obtain an empty carrier, and wait for the next circulation.

[0100] Next, when the transfer module as described above also includes an in-situ detection device, the two first side plates are arranged in sequence along the radial direction of the rotating member, and the two first side plates are provided with through holes at corresponding positions, the through holes are arranged close to the bottom plate, and the through holes are used for the signal of the in-situ detection device to pass through. The radial dimension of the through hole needs to be at least large enough not to block the detection signal. In specific applications, the first side plate of the carrier can be hollowed out, and one of the hollow holes constitutes the above-mentioned through hole. On the one hand, the hollow setting can reduce the overall weight of the carrier, and on the other hand, it can enhance the communication between the internal and external environments of the groove. For example, when it is necessary to use external temperature control devices, humidity control devices, etc. to adjust the ambient temperature, humidity, etc., or when ultraviolet lamps are needed to sterilize the hot pack semi-finished products, it is ensured that the carrier will not cause too much obstruction to the adjustment process.

[0101] The specific form of the picking device is not limited. Specifically, the second driving mechanism includes a first linear module and a second linear module. The first linear module includes a first guide portion provided on the second base and extending in the up-down direction, and a first movable portion movably mounted on the first guide portion in the up-down direction; the second linear module includes a second guide portion provided on the first movable portion and extending in a first horizontal direction (which may be one of the horizontal and longitudinal directions), and a second movable portion movably mounted on the second guide portion in the first horizontal direction; wherein the picking member includes a mounting portion and two clamping portions, the two clamping portions are movably mounted on the mounting portion in directions of approaching and moving away from each other, and the mounting portion is suspended at the second movable portion. The combination of the above-mentioned guide portion and movable portion is not limited, and may be, but is not limited to, a combination of a guide rail and a slider, a combination of a slide bar and a slide hole, etc. The active cooperation of the first guide part and the first movable part can realize the movement and adjustment of the picking part in the up and down directions; the active cooperation of the second guide part and the second movable part can realize the movement and adjustment of the picking part in the first horizontal direction, thereby enabling the picking part to be more accurately extended into the carrier at the second transfer position.

[0102] Furthermore, the second guide part is connected and fixed with a rotating shaft, and the rotating shaft is rotatably mounted on the first movable part around an axis extending in the vertical direction; the deflection mechanism includes a linear cylinder and a swing rod. The linear cylinder includes a cylinder body and a telescopic rod, one end of the cylinder body is rotatably mounted on the first movable part around an axis extending in the vertical direction, and the telescopic rod is telescopically arranged in a second horizontal direction; one end of the swing rod is connected and fixed with the rotating shaft, and the other end is movably hinged with the telescopic rod to drive the rotating shaft to deflect during the telescopic movement of the telescopic rod.

[0103] Based on any of the above embodiments, further, the transfer module also includes a weight detection device, which is arranged at the bottom of the carrier to send a weight sensing signal when a weight change occurs at the carrier. The weight detection device can be arranged between the carrier and the edge section, or it can be arranged in the groove and located at the upper end of the bottom plate. When the hot-packed semi-finished product is loaded into the carrier, the weight detection device detects the weight change, and firstly determines that the current carrier has been loaded with the hot-packed semi-finished product; then, according to the specific weight change, it can be determined whether the medicinal materials packaged in the current hot-packed semi-finished product meet the demand and meet the standards; and the weight value sensed after the hot-packed semi-finished product is picked up by the pick-up unit can determine whether the inner bag packaging of the current hot-packed semi-finished product is qualified, whether there is leakage and other abnormalities.

[0104] In addition, please combine Figure 10 to Figure 11 In one embodiment, the outer bag packaging module includes a conveying component, a second film supply component, two gathering components, a second sealer and a second cutter.

[0105] The conveying assembly includes two conveying sections arranged at intervals along the longitudinal direction, each conveying section extends along the longitudinal direction and together constitutes a second operating position, the interval between the two conveying sections constitutes a conveying gap, the two conveying sections are respectively a first conveying section located upstream of the conveying, and a second conveying section located downstream of the conveying, and the picking device is used to pick up the hot pack semi-finished product to the first conveying section.

[0106] In order to form the first conveying section and the second conveying section, the conveying assembly includes two conveying groups. Each conveying group includes a conveyor belt, a pulley and a motor. The conveyor belts extend longitudinally and move longitudinally under the drive of the motor. The above-mentioned picking device transfers the hot rammed semi-finished product at the second transfer position to the conveyor belt of the first conveying section. It can be understood that in order to facilitate the picking operation of the picking device, during the picking process of the picking device, the hot rammed semi-finished product generally presents a vertical posture. And it is placed at the first conveying section in this vertical posture.

[0107] In view of the above, in a further solution, the outer bag packaging module further includes a rotating plate, which is arranged at the first conveying section, and the upper end of the rotating plate swings around an axis extending in the transverse direction, and the lower end of the rotating plate faces the first conveying section, and an adjustment gap is defined between the rotating plate and the first conveying section, so that when the hot pack semi-finished product passes through the adjustment gap, it is pushed down by the rotating plate and adjusted from a vertical posture to a horizontal posture. The rotating plate can be roughly designed as a brush body, for example, or made of an elastic material, so that the hot pack semi-finished product can be pushed down more gently and without damage.

[0108] The second film supply assembly is arranged below the transmission gap and includes a plurality of second material rollers. The second material rollers are used to place the second film roll, and during the rotation of the second material rollers, the second film material of the second film roll is horizontally unfolded and released upward. The number and arrangement orientation of the second material rollers in the second film supply assembly can be adjusted according to actual needs. The second film supply assembly is located below the transmission gap, so that when the first transmission section is in the process of transferring the lying hot-wrapped semi-finished product to the second transmission section, it needs to pass through the second film material that is horizontally unfolded and released upward.

[0109] The rotation of the second material roller needs to be driven by a special power component. When at least one second material roller is actively rotated, the remaining second material rollers can be driven to passively rotate, thereby realizing the continuous release of the second film material. When the second film material reaches the second conveying section from bottom to top, it will be driven to move longitudinally to a certain distance synchronously with the second conveying section.

[0110] Of course, at least one of the second material rollers can also be set as a spare material roller. That is, the spare material roller can be pre-installed with at least one second film roll by a robot automatically or manually, thereby avoiding a long waiting time for the second film supply assembly.

[0111] In the above, the second film material is horizontally spread out and moves longitudinally along with the second conveying section. At this time, two gathering members are arranged on both lateral sides of the second conveying section and extend upwardly obliquely from the second conveying section to fold and gather the lateral sides of the horizontally spread second film material toward the middle of the two gathering members to form an outer bag that passes through in the longitudinal direction. The lateral sides of the outer bag are folded and covered on the semi-finished hot pack to form a center seam.

[0112] The second sealer is arranged in the second conveying section and is located downstream of the two gathering parts to seal the middle seam of the outer bag. Similarly to the above, the specific type and structure of the second sealer can be adjusted according to the material of the outer bag, that is, the material of the second film material. For example, when the second film material is a PP plastic film, the second sealer can be designed to be more suitable for sealing PP plastic films, such as an ultrasonic sealer, a hot press sealer, etc.

[0113] Specifically, in one embodiment, the second sealer includes two hot pressing wheel sets, a heater and a pressing plate.

[0114] Two hot pressing wheel groups are arranged above the second conveying section, and the two hot pressing wheel groups are arranged at intervals in the longitudinal direction. Each hot pressing wheel group includes two hot pressing rollers arranged in sequence in the transverse direction, and a hot pressing gap is defined between the two. Each hot pressing roller rotates around a fixed axis extending in the up and down directions so as to roll the center seam of the outer bag passing through the hot pressing gap during its rotation.

[0115] The heater acts on at least one hot pressing roller so that the hot pressing roller can perform hot pressing on the center seam of the outer bag passing through the hot pressing gap.

[0116] The pressing plate is arranged between the two hot pressing wheel groups and has a pressing surface arranged toward the second conveying section, and the pressing surface presses the middle seam of the outer bag passing through.

[0117] It should be noted that not all the hot pressing rollers in the two hot pressing roller groups need to be heated by the heater. That is, one or both of the two hot pressing roller groups can perform hot pressing and sealing on the outer bag. When one of the two hot pressing roller groups performs hot pressing and sealing on the outer bag, for example, the upstream hot pressing roller group performs hot pressing and sealing on the outer bag, the downstream hot pressing roller group can be configured to reinforce, confirm and shape the hot pressing and sealed middle seam of the outer bag during the extrusion process.

[0118] Of course, in other embodiments, the pressing plate can also be arranged downstream of the two hot pressing wheel groups. Or an additional pressing plate can be arranged downstream of the two hot pressing wheel groups. The outer bag can be shaped by pressing the pressing plate.

[0119] The second cutter is arranged in the second conveying section and is located downstream of the second sealer. The second cutter is used to cut and seal the two ends of the outer bag. Similarly to the above, the specific type and structure of the second cutter can be adjusted according to the material of the outer bag, that is, the material of the second film material. For example, when the second film material is a PP plastic film, the second cutter can be designed to be more suitable for sealing PP plastic films, such as an ultrasonic sealer, a hot press sealer, a cutter, etc.

[0120] Generally, the second cutter includes at least one cutter. Specifically, it can be a combination of a cutter and a backing plate facing each other, or a combination of two cutters facing each other. The cutter can be a single-edged cutter, or a rolling cutter with at least two blades. The cutter and the backing plate, and the two cutters have a movable stroke of approaching and moving away from each other, so that the outer bag can be cut in the process of approaching each other. In the process of moving away from each other, the heated bag can pass through. A heater can also be set at the second cutter to heat the cutter, so as to achieve heat sealing of the cut part of the outer bag.

[0121] It should be noted that the number and orientation of at least one of the above-mentioned conveying assembly, the second film supply assembly, the two gathering members, the second sealer and the second cutter can be adjusted according to actual needs. In addition, at least one of the above-mentioned conveying assembly, the second film supply assembly, the two gathering members, the second sealer and the second cutter can be fixedly connected to the third base in a fixed position. Or at least one of the above-mentioned conveying assembly, the second film supply assembly, the two gathering members, the second sealer and the second cutter can be designed as a movable connection with a flexible position adjustment relative to the third base, so as to enable translation adjustment, rotation adjustment, etc. in the horizontal, longitudinal and / or vertical directions.

[0122] In addition, based on one or more of the above embodiments, please refer to Fig.12 The present invention also provides a control method for a hot pack packaging device, comprising:

[0123] Step S100: acquiring the position information of the inner bag packaging module and the outer bag packaging module, and adjusting the first operating parameters of the rotating device and the picking device in the transfer module according to the position information.

[0124] It can be understood that, since the rotating device mentioned above can be adapted to the first transfer position and the second transfer position arbitrarily set in the horizontal direction by horizontal rotation, the purpose of transferring the hot-rolled semi-finished product from the first transfer position to the second transfer position is achieved. And the picking device can adjust the horizontal posture of the hot-rolled semi-finished product during its deflection. Therefore, in this embodiment, the setting of the relative positions of the inner bag packaging module and the outer bag packaging module has a higher degree of flexibility, and the inner bag packaging module and the outer bag packaging module can be arranged in an orientation according to actual needs, for example, to adjust the orientation according to the current production space. When the orientation information of the inner bag packaging module and the outer bag packaging module is determined, the relative orientation relationship between the first operating position and the second operating position is determined. Then, according to the above-mentioned orientation relationship, the rotation angle range of the rotating member in the rotating device, the picking height of the picking member, and the deflection angle of the deflection mechanism can be adjusted to better achieve the transfer of the hot-rolled semi-finished product.

[0125] Step S200: Acquire characteristic information of the hot pack, and adjust second operating parameters of the feeding module, the inner bag packaging module and the outer bag packaging module according to the characteristic information.

[0126] Step S300: According to the first operating parameter and the second operating parameter, the feeding module, the inner bag packaging module, the transfer module and the outer bag packaging module are controlled to operate in sequence.

[0127] In this embodiment, the characteristic information of the hot pack can be specifically set according to actual needs, for example, it can include but is not limited to the formula of the medicinal material, the quantity or quality of the medicinal material, the inner bag material and the outer bag material required for the medicinal material, the inner bag size and shape required for the medicinal material, the outer bag size and shape required for the medicinal material, etc. The characteristic information can be obtained in any way, such as manual input. Or after the information file is established in advance, the specific characteristic information is obtained by scanning the code, image recognition, etc. When the characteristic information is determined, the packaging scheme of the hot pack is also determined. That is, the second operating parameters corresponding to the feeding module, the inner bag packaging module and the outer bag packaging module are confirmed. It includes but is not limited to the operating parameters of the vacuum generator and the quantitative feeding screw in the feeding module; the operating parameters of the first film supply component, the first sealer, the two extrusion wheel groups and the first cutter in the inner bag packaging module; the operating parameters of the conveying component, the second film supply component, the second sealer and the second cutter in the outer bag packaging module, etc. In this way, it is helpful to make the packaging equipment of the hot pack provided by the present invention flexibly adaptable to the production and packaging of different hot packs.

[0128] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
