Description

Technical Field

[0001] The invention belongs to the field of bag arrangement of filling machines, and in particular relates to a synchronous bag arrangement and pushing device. Background Art

[0002] Filling machines are widely used in the food industry, beverage industry, daily chemical industry, etc. Filling machines have always been the solid backing of the beverage market, especially in the modern market, people's requirements for product quality are increasing, market demand is expanding, and enterprises require efficient and automated production. Under such circumstances, filling machines have become a hot filling equipment. In addition, with the improvement of scientific and technological levels in recent years, the domestic filling machine industry has also developed rapidly, and the technical level, equipment performance, quality and other aspects have been greatly improved, playing an important role in supporting enterprises to produce efficiently and safely.

[0003] After filling and sealing, the filling machine needs to transfer the formed packaging box to the packaging device through the station chain, and then the packaging device discharges the packaging box to the next conveying process. However, the packaging device of the existing filling machine directly discharges the packaging box onto the conveyor chain. In this way, in the process of discharging the packaging box, due to the excessively fast sliding speed of the packaging box, the conveyor chain continues to run at a high speed. When the bottom of the packaging box contacts the conveyor chain, the friction between the two gives the packaging box an initial velocity in the transmission direction of the conveyor chain, causing the packaging box to easily tip over or over on the conveyor chain. As the ratio of the height of the package to the length of the short side of the bottom surface increases, the center of gravity is high, resulting in a sharp increase in instability. In this way, it is easy to affect the operation of the next conveying link or cause the entire packaging process to be blocked, greatly reducing production efficiency and bringing great inconvenience to production.

[0004] Therefore, a packaging device that can control the stable transmission of packaging boxes has become a technical problem that needs to be solved urgently.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0044] Embodiment 1

[0045] like Figure 7 As shown, the present invention provides a package arranging and synchronous package pushing device for a filling machine, which is used for reliably and stably transferring formed packaging boxes to a conveyor chain. The filling machine includes a package arranging device for discharging packaging boxes to a conveyor chain, and the package arranging device includes a driving disk 17 and a package outlet channel for the packaging boxes to slide down. The driving disks 17 are arranged in pairs between the station chain terminal and the package outlet channel, and a conveying device for transmitting the packaging boxes is arranged between the paired driving disks 17. Preferably, in this embodiment, a slide plate is used.

[0046] The package evacuation and synchronous package pushing device comprises a driving assembly and a package pushing assembly, wherein the package pushing assembly is arranged between the package evacuation device and the conveyor chain; the driving assembly is used to drive the package pushing assembly to perform reciprocating motion on the conveyor chain; after the package evacuation device discharges the package box, the driving assembly drives the package pushing assembly to move along the transmission direction of the conveyor chain and gives the package box an initial velocity, so that the package box can be conveyed more stably; thereafter, the driving assembly drives the package pushing assembly to move in the opposite direction of the conveyor chain transmission and reset.

[0047] Under the action of the driving component, the bag pushing component reciprocates and circulates as the bag arranging device arranges bags, so that the bag arranging process can be completed stably and efficiently, greatly improving work efficiency.

[0048] The driving component is a linear reciprocating motion mechanism, and the package pushing component performs periodic linear reciprocating motion on the conveying chain driven by the linear reciprocating motion mechanism; the linear reciprocating motion mechanism can be a combination of one or more of the following: a push rod motor, a cylinder, a cam mechanism, etc. Preferably, a cam mechanism is selected in this embodiment.

[0049] The linear reciprocating motion mechanism uses a push rod motor. When the packaging box slides onto the conveyor chain, the push rod motor drives the package pusher to push the packaging box to move in the transmission direction of the conveyor chain. After the package is pushed, the package pusher resets to its initial position. The linear reciprocating motion mechanism uses a cylinder. The telescopic motion characteristics of the cylinder can be used to push the packaging box. Alternatively, a package pusher can be added. Driven by the telescopic motion of the cylinder, the package pusher can be further driven to reciprocate, thereby realizing the package pushing process.

[0050] Figure 1 The exploded view of the package pushing device for synchronous package discharge of the filling machine according to the present invention is shown.

[0051] like Figure 1 As shown, the cam mechanism includes a cam 1 which can rotate under the action of a driving force. The cam 1 rotates synchronously with the driving disk 17 of the above-mentioned packaging device, that is, every time the packaging device discharges a packaging box, the packaging pushing device completes a packaging pushing process. The discharging of packaging boxes here refers to the packaging boxes sliding onto the conveyor chain.

[0052] The cam 1 can be a curved cam or a cylindrical cam. Preferably, the cam 1 is cylindrical and has a concave annular groove in its axial direction, and the annular groove guides the bag pushing assembly to reciprocate on the conveyor chain; the annular groove of the cam 1 includes a first groove 101 and a second groove 102 that are interconnected, and the two grooves have a certain displacement difference in the axial direction of the cam 1.

[0053] The number of the first grooves 101 and the second grooves 102 on the cam 1 is set according to the number of packages arranged when the driving disk 17 of the package arranging device rotates one circle and the transmission ratio of the synchronous belt. For example, the driving disk 17 of the package arranging device arranges 3 packages when it rotates one circle, and the transmission ratio of the synchronous belt is 3:2, then 2 first grooves 101 with the same structure and 2 second grooves 102 with the same structure are set on the cam 1.

[0054] The cam mechanism also includes: a transmission shaft 3, to which a driving motor is connected, and the rotation frequency of the driving motor matches the rotation frequency of the driving disk 17 of the packaging device, so that the packaging pushing assembly pushes the packaging reciprocally along with the packaging process of the packaging device.

[0055] Preferably, in order to achieve better cycle matching, the present embodiment drives the package pushing assembly and the package discharging device through the same motor, that is, the transmission shaft 3 is connected to the driving disk 17 of the package discharging device through a belt and drives the cam 1 to rotate around the axial direction, so that the package discharging device and the package pushing device can rotate synchronously. When the package discharging device rotates, since the transmission shaft 3 is connected to the package discharging device through a belt, the transmission shaft 3 will also drive the cam 1 to rotate together, so that each time the package discharging device discharges a package, the package pushing device completes a package pushing process, and so on and so forth, so that the package discharging and pushing can be stably and reliably realized.

[0056] The transmission shaft 3 passes through the corresponding positions of the first vertical wall 4 and the second vertical wall 5 of the bag outlet channel, and a pulley 6 is fixed to the end of the transmission shaft 3 close to the first vertical wall 4, and the pulley 6 is connected to the driving disk 17 of the bag discharge device by a belt; the above-mentioned cam 1 is fixed to the other end of the transmission shaft 3 close to the second vertical wall 5.

[0057] The push bag assembly includes a telescopic guide rod 2, one end of which is in contact with the outer contour of the cam 1 and reciprocates under the drive of the cam 1. The telescopic guide rod 2 includes a guide portion 202 that can roll along the annular groove of the cam 1 and a guide portion 201 that can slide telescopically, and the guide portion 202 and the guide portion 201 form an L shape; a roller is provided on the guide portion 202, and the roller is fixed to the guide portion 202 with a screw; the sliding of the telescopic guide rod 2 in the groove of the cam 1 is achieved by the roller.

[0058] Specifically, during the rotation of the cam 1, the guide part 202 slides from the second groove 102 to the first groove 101, and the packaging box is just at the packaging position. The guide part 201 slides along the transmission direction of the conveyor chain and acts on the packaging box to make it have an initial speed and be conveyed to the conveyor chain; the guide part 202 slides from the first groove 101 to the second groove 102, and when the packaging box is away from the packaging position, the guide part 201 moves in the opposite direction of the conveyor chain transmission and resets, and continues to push the package next time, and such reciprocating motion enables the packaging process to be completed stably and efficiently, greatly improving work efficiency.

[0059] During the time from when the guide portion 202 is located in the first groove 101 one time to when it is located in the first groove 101 next time, the package pushing device completes one package pushing process.

[0060] The package discharging device comprises a package discharging channel, wherein the first vertical wall 4 and the second vertical wall 5 constitute the package discharging channel of the packaging box, wherein the second vertical wall 5 of the package discharging channel extends an extension end toward the position of the conveying chain, and the package pushing assembly is arranged on the extension end of the second vertical wall 5, and the extension end of the second vertical wall 5 is provided with a first hole 7 and a second hole 8. The telescopic guide rod 2 passes through the first hole 7 and can reciprocate in the first hole 7, and the package pushing process is performed through one end of the telescopic guide rod 2; the setting of the first hole 7 can support and guide the telescopic guide rod 2, so that the telescopic guide rod 2 can reciprocate in one direction, thereby achieving the stability of the package pushing.

[0061] like Figure 2 and Figure 3 As shown, in order to prevent the telescopic guide rod 2 from rotating during the reciprocating motion, preferably, the push bag assembly further includes a baffle 9 and a guide shaft 10, one end of the guide shaft 10 and one end of the telescopic guide rod 2 are both mounted on the baffle 9 by screws; the guide shaft 10 is movably arranged in the second hole 8 on the extension end, and the movably arranged here means that the guide shaft 10 can move back and forth in the second hole 8. By adding the baffle 9 and the guide shaft 10, the telescopic guide rod 2 can be prevented from rotating when sliding, so that the telescopic guide rod 2 and the cam 1 are always in contact, so that the telescopic guide rod 2 can reciprocate in an orderly and uninterrupted manner, thereby improving the stability and reliability of the push bag.

[0062] Preferably, the package pushing assembly also includes a push plate 11, and the other end of the telescopic guide rod 2 and the other end of the telescopic guide rod 2 are respectively mounted on the push plate 11 by screws; the setting of the push plate 11 not only increases the contact area with the packaging box, so that the packaging box is evenly stressed, but also can further prevent the telescopic guide rod 2 from rotating.

[0063] The push bag assembly also includes a sliding bearing 12, which is screwed into the first hole 7, and the telescopic guide rod 2 passes through the first hole 7 and is arranged in the sliding bearing 12, and the telescopic guide rod 2 can slide back and forth in the sliding bearing 12. The telescopic guide rod 2 slides in the sliding bearing 12, which can reduce the friction force on the telescopic guide rod 2 during the sliding process, thereby extending the service life of the telescopic guide rod 2.

[0064] Preferably, a baffle for preventing the packaging box from falling is fixed in the vertical direction of the extended end of the second vertical wall 5, and the baffle is directly opposite to the package outlet.

[0065] Specifically, the formed packaging box is transmitted to the slide of the packaging arrangement device through the station chain, and the slide conveys the packaging box to the packaging outlet channel. When the packaging box slides down to the conveyor chain through the packaging outlet channel, the packaging pushing device just reaches the landing point of the packaging box. The packaging pushing device pushes the packaging box in the transmission direction of the conveyor chain, so that the packaging box has an initial speed in the direction of the conveyor chain; after the pushing of the package is completed, the pushing device returns to the original point of pushing the package and continues the next pushing of the package, thus realizing the process of continuous transportation of the packaging box in a cyclic operation.

[0066] The present invention arranges a package pushing device at the package discharge outlet position, which gives a pushing force along the conveying direction of the conveying chain to the package box that slides onto the conveying chain, so that the package box is not easy to overturn, so that the package box can be stably conveyed; the setting of the baffle can make the package box fall exactly at the designated position, which can prevent the package box from falling to the ground due to excessive speed.

[0067] Embodiment 2

[0068] like Figure 4 As shown, the difference between this embodiment and the above embodiment is that a package discharge synchronization buffer device is symmetrically added on the two vertical walls at the package discharge position of the package discharge device, including an elastic device, which is respectively installed on the first vertical wall 4 and the second vertical wall 5. The first vertical wall 4 and the second vertical wall 5 form a package discharge channel for the packaging box to slide down. During the package discharge process of the package discharge device, the elastic device comes into contact with the packaging box to buffer the speed of the packaging box.

[0069] Preferably, the elastic device is symmetrically installed on the package outlet channel of the package discharge device; the elastic device is symmetrically arranged on the package outlet channel so that the two sides of the packaging box are evenly stressed, so that the packaging box can slide in the center.

[0070] Specifically, the formed packaging box is transferred to the slide of the packaging arrangement device through the station chain, and the slide transfers the packaging box to the packaging outlet channel. During the sliding down of the packaging outlet channel, the packaging box comes into contact with the elastic device, which not only makes the packaging box slide in the center on the packaging outlet channel and is not easy to swing left and right, but also slows down the sliding speed of the packaging box, so that the packaging box is cushioned, so that the packaging box is not easy to overturn when it falls on the conveyor chain.

[0071] The elastic device comprises an elastic component. Preferably, in this embodiment, the elastic component comprises a spring sheet and a mounting seat.

[0072] like Figure 5 , showing an exploded view of the synchronous buffer device for packing in this embodiment.

[0073] A first elastic component 13 is installed on the first vertical wall 4 of the bag outlet channel of the bag discharge device, and a second elastic component 14 is installed on the second vertical wall 5; the first elastic component 13 includes a first elastic sheet 1301 and a first mounting seat 1302, and the second elastic component 14 includes a second elastic sheet 1401 and a second mounting seat 1402.

[0074] Preferably, the distance between the free ends of the first elastic sheet 1301 and the second elastic sheet 1401 is smaller than the width of the package box in the transverse direction of the package outlet passage; further, the distance between the free ends of the first elastic sheet 1301 and the second elastic sheet 1401 is 80% of the maximum width of the package box, and the size of the distance is set according to the width of the specific package box. In this way, the sliding speed of the package box can be effectively slowed down by clamping the two sides of the package box and the package box can be controlled to maintain the centering slide when sliding down.

[0075] The first spring piece 1301 and the second spring piece 1401 are respectively arranged to be inclined toward the package outlet channel. Preferably, a certain angle is formed between the first spring piece 1301 and the second spring piece 1401, and the range of the angle is: 10° to 20°.

[0076] The first mounting seat 1302 is fixed on the first vertical wall 4 of the bag outlet passage by screws; the first mounting seat 1302 includes: a first connecting portion 1303 , a first connecting seat 1304 and a first stopper 1305 .

[0077] The first connection part 1303 is provided with two strip holes, through which it can be adjustably mounted on the first vertical wall 4 of the bag outlet passage; the adjustable mounting mentioned here means that the mounting position of the first connection part 1303 can be arbitrarily selected within the range of the strip holes.

[0078] The first connecting seat 1304 is vertically fixed to one end of the first connecting portion 1303 and is provided with two mounting holes for mounting the first elastic piece 1301 .

[0079] The first stopper 1305 is vertically fixed to the other end of the first connecting portion 1303, provides support force to the first spring piece 1301, and is arranged in the middle of the first spring piece 1301 to control the vibration amplitude of the first spring piece 1301 within a certain range. In this way, the first stopper 1305 can not only assist in providing a greater buffer force, but also better slow down the sliding speed of the packaging box; it can also control the amplitude of the first spring piece 1301, so that the first spring piece 1301 can quickly return to a natural state.

[0080] The second mounting seat 1402 is fixed on the second vertical wall 5 of the bag outlet passage by screws; the second mounting seat 1402 includes: a second connecting portion 1403 , a second connecting seat 1404 and a second stopper 1405 .

[0081] The second connection part 1403 is provided with two strip holes, through which it can be adjustably mounted on the second vertical wall 5 of the bag outlet passage; the adjustable mounting mentioned here means that the mounting position of the second connection part 1403 can be arbitrarily selected within the range of the strip holes.

[0082] The second connecting seat 1404 is vertically fixed to one end of the second connecting portion 1403 and is provided with two mounting holes for mounting the second elastic piece 1401 .

[0083] The second stopper 1405 is vertically fixed to the other end of the second connecting portion 1403, provides support force to the second spring piece 1401, and is arranged at the middle position of the second spring piece 1401 to control the vibration amplitude of the second spring piece 1401 within a certain range. In this way, the second stopper 1405 can not only assist in providing a greater buffer force, but also better slow down the sliding speed of the packaging box; it can also control the amplitude of the second spring piece 1401, so that the second spring piece 1401 can quickly return to a natural state.

[0084] Two strip holes for adjusting the installation position of the first elastic piece 1301 are provided on the installation end of the first elastic piece 1301 , and the free end of the first elastic piece 1301 is wedge-shaped.

[0085] Two strip holes for adjusting the installation position of the second elastic piece 1401 are provided on the installation end of the second elastic piece 1401 , and the free end of the second elastic piece 1401 is wedge-shaped.

[0086] Specifically, during installation, the distance between the first spring piece 1301 and the second spring piece 1401 can be adjusted by adjusting the installation position of the first spring piece 1301 and / or the second spring piece 1401 and / or the first mounting seat 1302 and / or the second mounting seat 1402, which is simple and convenient to operate.

[0087] Preferably, in actual application, in order to achieve a better buffering effect, the friction force on the surface of the spring sheet 1 can be increased to buffer the downward movement of the packaging box.

[0088] When the packaging device is working, the formed packaging box is transferred from the station chain to the packaging outlet channel. During the sliding down of the packaging box in the packaging outlet channel, the free ends of the first spring piece 1301 and the second spring piece 1401 come into contact with the two sides of the packaging box, so that the packaging box has a short stay process, thus effectively slowing down the sliding speed of the packaging box.

[0089] The present invention installs an elastic buffering device at the package discharge outlet, which not only has good centering, but also can effectively slow down the sliding speed of the package box, so that the package box is not easy to overturn when it slides down to the conveyor chain, so that the package box can be transmitted to the next transmission process in an orderly and stable manner.

[0090] Embodiment 3

[0091] like Figure 1 and Figure 6 As shown, the difference between this embodiment and the above-mentioned embodiment is that a transition device is arranged on the base of the conveyor chain, and the transition device includes a transition plate 15 and a transition plate bracket 16, and the transition plate 15 is adjustably mounted on the transition plate bracket 16, and the transition plate bracket 16 is fixed on the base of the conveyor chain.

[0092] The transition plate 15 is rectangular and is provided with a strip hole, through which the fixing position of the transition plate 15 can be adjusted; the transition plate 15 is parallel to the conveyor chain, and when the packaging box slides down, it falls on the transition plate 15 .

[0093] The transition plate bracket 16 is U-shaped, and is provided with mounting holes for fixing the transition plate 15 ; both ends of the opening of the transition plate bracket 16 are fixed on the base of the conveyor chain.

[0094] The setting of the transition plate of the present invention changes the landing point of the packaging box, so that the packaging box does not slide directly onto the conveyor chain but slides onto the transition plate. In this way, the packaging box will not be affected by the transmission force of the conveyor chain when it lands, further increasing the stability and continuity of the package pushing.

[0095] Embodiment 4

[0096] like Figure 7 As shown, on the basis of the above embodiment, the package discharge device also includes a package clamping device, which includes a second cam and a telescopic rod 18. The second cam is coaxially arranged with the driving disk 17 and has an annular groove. The second cam is detachably installed in the driving disk 17. The telescopic rod 18 is evenly distributed on the driving disk 17 and can move along the second cam under the drive of the driving disk 17; the mechanism composed of the cam and the driving disk 17 is arranged in pairs between the terminal of the station chain and the package outlet channel. Under the drive of the driving force, the telescopic rod 17 can clamp the packaging boxes on the station chain from both sides respectively and transport the packaging boxes to the package outlet channel.

[0097] Specifically, when the formed packaging box is located at the end of the station chain, the telescopic rod extends out and clamps the packaging box from both sides for further transmission, and reaches the elastic device, releasing the packaging box to allow it to slide freely. The free end of the first spring sheet and the free end of the second spring sheet of the elastic device contact the packaging box and generate a buffering force, which slows down the sliding speed of the packaging box, so that the packaging box can stably land on the transition plate of the package pushing device, and the package pushing device pushes the packaging box to the conveyor chain.

[0098] The present invention can discharge the packaging boxes smoothly from the station chain without squeezing or damaging the packaging boxes. The packaging boxes can slide centrally on the sliding channel and are not prone to overturning, so that the entire packaging arrangement and pushing process can be carried out in an orderly manner, thereby improving work efficiency and the stability of the entire production.

[0099] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
