Description

Technical Field

[0001] This application relates to the technical field of machinery for food production, and in particular to a packaging and packing machine. Background Technology

[0002] Currently, in the production process of products such as glutinous rice mochi balls, the filling needs to be wrapped in the dough first by a filling machine. Multiple products with filling are then transported to a tray-arranging machine in sequence. The tray-arranging machine throws the products into a tray, so that the products are arranged in order on the tray before subsequent operations are carried out.

[0003] In related technologies, products with sticky outer skins, such as glutinous rice mochi balls, are prone to sticking to the conveyor belt during the transportation process between various devices, which has a significant impact on product integrity and hygiene. Furthermore, the tray-laying machine and conveyor belt require a large space, and the equipment cost is relatively high. Summary of the Invention

[0004] In order to reduce the process of transporting products between multiple devices, maintain product integrity and hygiene, and reduce production costs, this application provides an integrated packaging and packing machine.

[0005] The integrated packaging and stacking machine provided in this application adopts the following technical solution:

[0006] A wrapping and arranging machine includes a frame, on which a wrapping device for producing finished products is installed. A support frame is installed below the discharge end of the wrapping device. A tray for placing finished products is installed on the support frame. A transverse conveying device for driving the tray to slide along the length of the tray is installed on the support frame. A sliding device for driving the tray to move along the width of the tray is also installed on the frame. A powder-sprinkling device is installed at each end of the transverse conveying device.

[0007] By employing the above technical solution, workers place the dough and filling into the filling device, which then outputs the shaped product, which falls vertically downwards. Simultaneously, workers place a tray at one end of a horizontal conveyor, which moves the tray to the underside of the powder-spreading device on that side.

[0008] The powder-sprinkling device sprinkles powder onto the tray. The lateral conveying device and sliding device adjust the relative position of the tray and the filling device, so that the formed products fall vertically onto the preset positions on the tray, and the products formed in the filling device fall into the tray. Then, through further adjustments by the lateral conveying device and sliding device, the next formed product from the filling device falls onto another preset position on the tray, until the tray is full. The lateral conveying device then moves the tray to the other side, passing the powder-sprinkling device on that side, sprinkling powder onto the tray, and then the lateral conveying device moves the tray out of the workstation corresponding to the filling device.

[0009] Preferably, the transverse conveying device includes two sprockets and a synchronous chain. The axes of the two sprockets are parallel to the width direction of the tray. The two sprockets are spaced apart along the length direction of the tray. The synchronous chain is wound around the two sprockets. A transverse drive motor is mounted on the support frame. The output shaft of the transverse drive motor is coaxially fixed to any one of the sprockets. Fixed posts are fixed on the synchronous chain. The fixed posts are perpendicular to the synchronous chain. Multiple fixed posts are evenly spaced along the length direction of the synchronous chain. The tray is positioned between two adjacent fixed posts.

[0010] By adopting the above technical solution, the horizontal drive motor rotates to drive the synchronous chain forward, and the fixed column on the synchronous chain pushes the pallet to move along the length direction, so that the pallet can move smoothly on the support frame in this way.

[0011] Preferably, a sensing baffle is also connected to the output shaft of the transverse drive motor. The sensing baffle is provided with a sensing notch. The support frame is also provided with a first photoelectric sensor for detecting the sensing notch. When the first photoelectric sensor corresponds to the sensing notch, the filling device is located between two adjacent fixed columns along the synchronous chain forward direction. The frame is also provided with a control device, which is electrically connected to the filling device, the transverse drive motor and the first photoelectric sensor respectively.

[0012] By adopting the above technical solution, the control device can sense the tray through the first photoelectric sensor.

[0013] The relative position on the support frame allows workers to easily control the horizontal drive motor, thereby controlling the filling device's discharge and the tray's forward speed.

[0014] Preferably, the support frame is further provided with positioning plates, which are vertically arranged. There is one positioning plate on each side of the pallet width direction, and the two positioning plates expand outward at both ends along the length direction. The transverse conveying device is arranged between the two positioning plates.

[0015] By adopting the above technical solution, the positioning plate helps to ensure the stability of the pallet on the support frame and reduces the possibility that the pallet will slide to one side due to inertia when the transverse conveying device or sliding device moves.

[0016] Preferably, the support frame is provided with a fixing block on one side along the width direction of the pallet. The fixing block is located on either side of the two positioning plates that are opposite to each other. The fixing block is provided with a bolt. The axis of the bolt is parallel to the width direction of the pallet. The bolt passes through the fixing block along its own axis and is threaded to the fixing block. The end of the bolt is rotatably connected to the positioning plate on the corresponding side. Multiple fixing blocks are provided at intervals along the length direction of the positioning plate. There is one row of fixing blocks on each side of the two positioning plates that are opposite to each other.

[0017] By adopting the above technical solution, workers can adjust the distance between the two positioning plates and the relative position between any positioning plate and the support frame by adjusting the relative positions of the bolts and the fixing blocks, so that the positioning plates can be used for different types of pallets. This helps to improve the applicability of the entire equipment.

[0018] Preferably, the sliding device includes two synchronous pulleys and a synchronous belt. The axes of the two synchronous pulleys are parallel to the length direction of the tray, and the two synchronous pulleys are spaced apart along the width direction of the tray. The synchronous belt is wound around the two synchronous pulleys. The support frame is fixed relative to a portion of the upper side of the synchronous belt. A synchronous motor is also mounted on the frame, and the output shaft of the synchronous motor is connected to any one of the synchronous pulleys.

[0019] Each synchronous pulley is fixed coaxially.

[0020] By adopting the above technical solution, the output shaft of the synchronous motor drives the corresponding synchronous pulley to rotate, thereby driving the synchronous belt to move forward or backward, and driving the support frame to slide along the width of the tray, thereby changing the relative position between the tray and the filling device.

[0021] Preferably, a linear guide rail is provided on the lower side of the support frame. The length direction of the linear guide rail is parallel to the width direction of the tray. The linear guide rail is fixed on the frame. A slider is provided on the linear guide rail. The linear guide rail passes through the slider along its own axis. The linear guide rail and the slider slide and cooperate along their own axis. The support frame and the slider are relatively fixed.

[0022] By adopting the above technical solutions, the linear guide and slider help to limit the support frame, reduce the occurrence of timing belt slippage, and improve the stability of the sliding device.

[0023] Preferably, the frame is equipped with a second photoelectric sensor and a third photoelectric sensor, and the support frame is equipped with a baffle. When the baffle corresponds to the second photoelectric sensor, a row of forming grooves on the tray below the filling device, near the filling device, corresponds to the discharge end of the filling device. When the baffle corresponds to the third photoelectric sensor, a row of forming grooves on the tray below the filling device, away from the filling device, corresponds to the discharge end of the filling device. The frame is also equipped with a control device, which is electrically connected to the filling device, the synchronous motor, the second photoelectric sensor, and the third photoelectric sensor.

[0024] By adopting the above technical solution, the staff can use the control device to determine the relative position of the support frame in the direction of the synchronous belt movement based on whether the second photoelectric sensor and the third photoelectric sensor detect the baffle. This allows them to control the synchronous motor, thereby changing the relative position of the tray and the filling device, and simultaneously controlling the filling device to discharge material.

[0025] Preferably, any of the powder-spreading devices includes a conical box, the conical box being open on both the upper and lower sides.

[0026] The cone-shaped box is designed to taper vertically from top to bottom. A brush is fixed inside the cone-shaped box, and the brush is located at the lower opening of the cone-shaped box. The diameter of the brush is larger than the diameter of the lower opening of the cone-shaped box.

[0027] By adopting the above technical solution, the staff pours the anti-sticking powder into the conical box from the top. The brush inside the conical box prevents the anti-sticking powder from falling directly. When the brush brushes over the lower tray, the anti-sticking powder will fall onto the tray.

[0028] Preferably, any of the conical boxes is further provided with stirring teeth, and a stirring motor is provided on the upper side of the conical box. The housing of the stirring motor is fixed relative to the frame, the output shaft of the stirring motor is coaxially arranged with the conical box, and the output shaft of the stirring motor is fixedly connected to the stirring teeth.

[0029] By adopting the above technical solution, the continuously rotating stirring teeth help reduce the clumping of anti-sticking powder in the conical box, while ensuring that the brush is covered with anti-sticking powder and reducing the amount of anti-sticking powder adsorbed in the conical box due to static electricity.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By integrating the filling device, tray, and the lateral conveying and sliding device that drives the tray into one device, the stickiness of highly viscous products during the conveying process is reduced, while production efficiency is improved and the consistency of products leaving the factory is guaranteed.

[0032] 2. The setting of the first photoelectric sensor, the sensing baffle, the baffle plate, the second photoelectric sensor, the third photoelectric sensor, and the control device helps the staff to determine the relative position between the tray and the filling device, and facilitates the staff to control the filling device to discharge material.

[0033] 3. The combination of the conical box structure of the powder-spreading device and the stirring motor ensures uniform powder distribution, reduces powder clumping, and thus ensures long-term efficient operation of the powder-spreading device, improving the overall reliability of the equipment. There is a powder-spreading box on each side, distributing powder before and after the product enters the tray.

[0034] After placing the tray, sprinkle powder onto the tray to help reduce the amount of product sticking to the equipment. Attached Figure Description

Detailed Implementation

[0040] The following is in conjunction with the appendix Figs. 1-4 This application will be described in further detail.

[0041] This application discloses a packaging and packaging integrated machine.

[0042] In this embodiment, the tray 6 is formed with multiple forming grooves, which are evenly spaced along the length and width of the tray 6.

[0043] See Figs. 1-4 The dough wrapping machine includes a frame 1, on which a filling device 2 is mounted. The filling device 2 includes a dough extruder 21 and a filling extruder 22. The outlet ends of the dough extruder 21 and the filling extruder 22 are connected by rectifiers 23. A filling body 24 is positioned between the two rectifiers 23. After the rectifiers 23 extrude the dough or filling into the filling body 24, the filling body 24 has a built-in guide channel that allows the filling to be wrapped inside the dough. A filling cutter disc 25 is also mounted below the filling body 24. The filling cutter disc 25 cuts the long strips of dough produced by the filling body 24 into spherical shapes, which then fall vertically downwards. A support frame 11 is also mounted below the filling cutter disc 25, on which a transverse conveyor 3 is mounted, and on which a tray 6 is mounted. A powder-sprinkling device 5 is mounted on each side of the transverse conveyor 3 along the length of the tray 6. The frame 1 is also equipped with a sliding device 4.

[0044] In practice, workers add the dough and filling to the dough extruder 21 and filling extruder 22 respectively. The dough extruder 21 and filling extruder 22 extrude the dough or filling into the corresponding rectifier 23. The rectifier 23 then extrudes the dough and filling into the filling body 24. The filling body 24 wraps the filling inside the dough and extrudes long strips of filled dough. The filling cutter 25 cuts the dough into round balls and shapes them for filling. The transverse conveyor 3 and the sliding device 4 move the tray 6. First, it passes through the powdering device 5 on one side, which sprinkles anti-sticking powder onto the tray 6. Then, the lower end of the filling cutter 25 aligns with the preset position on the tray 6. The dough, now filled and shaped, falls vertically into the tray 6. The rectifier 23 continues to extrude the filled dough. After being shaped by the filling cutter 25, the transverse conveyor 3 and the sliding device 4 move the tray 6 to the next position, where the dough falls into the tray 6. This process is repeated until the filled dough fills the tray 6. The transverse conveyor 3 then moves the tray 6 to one side, away from the bottom of the filling device 2. After being sprinkled with powder by another powdering device 5, the worker can remove the tray 6.

[0045] The frame 1 is also equipped with a control device, which can be configured as a PLC integrated module including a processor and components such as a power supply, control screen, and buttons electrically connected to the processor.

[0046] Each powder-spreading device 5 includes a conical box 51, which is open on both the top and bottom sides and tapers vertically from top to bottom. The conical box 51 is fixed relative to the frame 1. A brush 52 is fixed inside the conical box 51, located at the lower opening of the conical box 51, and the diameter of the brush 52 is larger than the diameter of the lower opening of the conical box 51. A stirring tooth 53 is also provided inside the conical box 51. A stirring motor 54 is mounted on the upper side of the conical box 51. The housing of the stirring motor 54 is fixed relative to the frame 1, and the output shaft of the stirring motor 54 is coaxial with the conical box 51. The output shaft of the stirring motor 54 is fixedly connected to the stirring tooth 53. The brush 52 is fixed at the lower end of the stirring tooth 53 and is coaxial with the output shaft of the stirring motor 54. A protective cover 55 is provided on the stirring motor 54.

[0047] The transverse conveying device 3 includes two sets of conveying components. Each set of conveying components includes two sprockets 31 and a synchronous chain 32. The axes of the two sprockets 31 are parallel to the width direction of the tray 6.

[0048] Two sets of conveying components are spaced apart along the length of the pallet 6, with a synchronizing chain 32 wound around each sprocket 31. Two sets of conveying components are spaced apart along the width of the pallet 6. Two sprockets 31 on either side of the pallet 6 are coaxially fixed. A transverse drive motor 36 is mounted on the support frame 11, and a reducer 37 is mounted on one side of the transverse drive motor 36. The output shaft of the transverse drive motor 36 is coaxially fixed with the input shaft of the reducer 37, and the output shaft of the reducer 37 is connected to either sprocket 31 via a belt and pulley. A fixing post 33 is fixed to each synchronizing chain 32, perpendicular to the synchronizing chain 32. Multiple fixing posts 33 are evenly spaced along the length of the synchronizing chain 32, with the pallet 6 positioned between two adjacent fixing posts. Fixing posts at the same position on the two sets of conveying components are located on opposite sides of the two synchronizing chains 32 along the width of the pallet 6.

[0049] A drive gear 371 is also coaxially fixed on the output shaft of the reducer 37, and a rotating support frame 11 is also mounted on it.

[0050] A sensing baffle 38 is provided, with its axis parallel to the width direction of the support frame 11. The sensing baffle 38 is vertically positioned, and a driven gear is coaxially fixed on it. The drive gear 371 meshes with the driven gear. Sensing notches are formed on the sensing baffle 38, one on each side of the axis. A first photoelectric sensor 39 is also provided on the support frame 11, electrically connected to the control device. The filling device 2 and the transverse drive motor 36 are electrically connected to the control device. When the first photoelectric sensor 39 detects a corresponding sensing notch, the forming groove on the first column of the synchronous chain 32 below the filling device 2 aligns with the discharge end of the filling device 2. The control device controls the filling device 2 to discharge material and simultaneously controls the transverse drive motor 36 to drive the synchronous chain 32 forward, thus moving the tray 6 forward.

[0051] The support frame 11 is also equipped with positioning plates 34, which are vertically arranged. There is one positioning plate 34 on each side of the pallet 6 in the width direction. The two positioning plates 34 are close to each other and abut against the two sides of the pallet 6 in the width direction. The two positioning plates 34 expand outward at both ends in the length direction. The transverse conveying device 3 is arranged between the two positioning plates 34. The support frame 11 is equipped with a fixing block 35 on one side of the pallet 6 in the width direction. The fixing block 35 is located on either side of the two positioning plates 34 that are opposite to each other. The fixing block 35 is equipped with a bolt 351. The axis of the bolt 351 is parallel to the width direction of the pallet 6. The bolt 351 passes through the fixing block 35 along its own axis and is threadedly connected to the fixing block 35. The end of the bolt 351 is rotatably connected to the corresponding side of the positioning plate 34. Multiple fixing blocks 35 are arranged at intervals along the length direction of the positioning plate 34. There is one row of fixing blocks 35 on each side of the two positioning plates 34 that are opposite to each other.

[0052] The sliding device 4 includes two synchronous pulleys 41 and a synchronous belt 42. The axes of the two synchronous pulleys 41 are parallel to the length direction of the tray 6, and the two synchronous pulleys 41 are spaced apart along the width direction of the tray 6. The synchronous belt 42 is wound around the two synchronous pulleys 41. The support frame 11 and a part of the upper belt body of the synchronous belt 42 are also included.

[0053] A synchronous motor 45 is also installed on the frame 1, which is relatively fixed. The housing of the synchronous motor 45 is fixed to the frame 1, and the output shaft of the synchronous motor 45 is coaxially fixed with any one of the synchronous pulleys 41. The rotation of the synchronous motor 45 drives the synchronous belt 42 to move forward or backward. A linear guide rail 43 is installed on the lower side of the support frame 11. The length direction of the linear guide rail 43 is parallel to the width direction of the tray 6. The linear guide rail 43 is fixed to the frame 1, and a slider 44 is installed on the linear guide rail 43. The linear guide rail 43 passes through the slider 44 along its own axis, and the linear guide rail 43 and the slider 44 slide and cooperate along their own axes. The support frame 11 and the slider 44 are relatively fixed. One set of linear guide rail 43 and slider 44 is provided on each side of the synchronous belt 42 in the width direction.

[0054] The frame 1 is also equipped with a second photoelectric sensor 46 and a third photoelectric sensor 47, which are spaced apart along the forward direction of the synchronous belt 42. The second photoelectric sensor 46 is located on the side closer to the filling device 2. A baffle 441 is fixed on either side of the slider 44, located between the second photoelectric sensor 46 and the third photoelectric sensor 47. When the discharge end of the filling device 2 corresponds to a row of forming grooves on the side of the tray 6 near the filling device 2, the baffle 441 corresponds to the second photoelectric sensor 46; when the discharge end of the filling device 2 corresponds to a row of forming grooves on the side of the tray 6 away from the filling device 2, the baffle 441 corresponds to the third photoelectric sensor 47. The second photoelectric sensor 46, the third photoelectric sensor 47, and the synchronous motor 45 are electrically connected to the control device. In actual operation, the control device can detect the relative position of the tray 6 under the filling device 2 in the forward direction of the synchronous belt 42 through the second photoelectric sensor 46 and the third photoelectric sensor 47, thereby controlling the discharge of the filling device 2.

[0055] The implementation principle of the integrated bagging and filling machine according to this application embodiment is as follows: Workers add dough and filling to the hoppers of the dough extruder 21 and filling extruder 22 respectively, and pour anti-sticking powder into the conical boxes 51 on both sides. In actual operation, the dough extruder 21 and filling extruder 22 respectively extrude the dough or filling into the corresponding rectifier 23, and the rectifier 23 then extrudes the dough and filling into the bagging machine.

[0056] Inside the filling body 24, the filling body 24 wraps the filling inside the dough and extrudes long strips of filled dough. The filling cutter 25 cuts the dough into spherical dough balls and shapes them. Simultaneously, the operator places multiple trays 6 between two adjacent sets of fixed posts 33 along the forward direction of the synchronous chain 32. The transverse drive motor 36 drives the output shaft of the reducer 37 to rotate, which in turn drives the corresponding sprocket 31 and drive gear 371 to rotate. The drive gear 371 drives the driven gear to rotate, thereby driving the induction baffle 38 to rotate. The sprocket 31 drives the synchronous chain 32 to move forward or backward. The synchronous motor 45 drives the synchronous pulley 41 to rotate, which in turn drives the synchronous belt 42 to move forward or backward. The synchronous belt 42 drives the support frame 11 to move. The control device monitors the relative position between the trays 6 and the filling device 2 through the first photoelectric sensor 39, the second photoelectric sensor 46, and the third photoelectric sensor 47, thereby controlling the filling cutter 25 to make the spherical dough balls fall sequentially onto the corresponding positions on the trays 6.

[0057] The horizontal drive motor 36 and synchronous motor 45 move the pusher plate horizontally to the next position, and the next spherical dough ball falls into the tray 6. This process is repeated until the tray 6 is full of dough. The horizontal drive motor 36 then drives the synchronous chain 32 forward, moving the tray 6 full of dough out from under the filling device 2. The empty tray 6 moves into the filling device 2, and the tray arrangement is repeated. The tray 6, after being removed from under the filling device 2, passes through the powdering device 5 on the other side, where powder is sprinkled onto the dough. The operator can then remove the full tray 6 from the equipment. This method allows for simultaneous filling and tray arrangement, helping to reduce the impact of sticky dough transport between multiple devices on product integrity and hygiene. It also reduces the number of devices, lowers equipment costs, and ultimately reduces production costs.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
