Description

Technical Field

[0001] The present application belongs to the technical field of soymilk production equipment, and specifically relates to a nozzle bag pre-positioning transfer device. Background Art

[0002] Soy milk is a beloved beverage in China and a nutritious food suitable for all ages. Known as "plant milk" in Europe and the United States, it is rich in plant protein and phospholipids, as well as vitamins B1 and B2, iron, and calcium. During mass production, soy milk needs to be bottled into spout bags for storage.

[0003] In the related art, for example, Chinese utility model patent No. CN210175278U discloses a spout bag filling and capping production line, which includes a turntable, a control device, a turntable drive device for driving the turntable, and a bag hanging mechanism, a filling mechanism, a capping mechanism, a capping and synchronous torque detection mechanism, and a finished product delivery mechanism arranged in sequence along the circumference of the turntable. The edge of the turntable is provided with multiple workstations, each of which is provided with multiple spout bag hanging units. The spout bag hanging unit has a spout bag hanging groove, and the spout bag is hung in the spout bag hanging groove. When filling soy milk, the spout bag on the spout bag hanging groove moves to the turntable under the action of the bag hanging mechanism, and the filling mechanism fills it with soy milk. Then, the capping mechanism puts the bottle cap on the spout bag, and the capping and synchronous torque detection mechanism screws the bottle cap. Finally, the spout bag filled with soy milk is separated from the turntable by the action of the finished product delivery mechanism.

[0004] At present, the spout bag is hung in the spout bag hanging groove first, and then, after all the spout bags on the spout bag hanging grooves located on the side of the turntable are hung on the turntable, the spout bag is added to the spout bag hanging groove; in order to improve the filling efficiency of soy milk, it is usually necessary to hang the spout bag in the spout bag hanging groove first, and then place the spout bag hanging groove on a transfer vehicle, so that when the spout bag needs to be added, the transfer vehicle can be directly pushed to the turntable to directly replace the spout bag hanging groove.

[0005] However, the existing spout bag hanging trough is usually supported on the transfer vehicle at both ends so that the transfer vehicle supports it. However, when the transfer vehicle is pushed, the spout bag hanging trough may move relative to the transfer vehicle, causing the spout bag hanging trough to fall from the transfer vehicle, and then the staff needs to place the spout bag hanging trough on the transfer vehicle again, and even need to re-hang the spout bag on the spout bag hanging trough, which affects the filling efficiency of the soy milk. Utility Model Content

[0006] The present application provides a spout bag pre-positioned transfer device to increase the stability of the spout bag hanging groove during the transfer process and ensure the filling efficiency of soy milk.

[0007] The technical solutions adopted in this application are:

[0008] A device for pre-loading and transferring a spout bag comprises a frame and running wheels arranged on the frame. The frame has suspension cavities arranged in sequence from top to bottom. The opposite cavity walls of the suspension cavities are correspondingly provided with support members. The support members are provided with positioning members. The positioning members have a limiting groove for accommodating the end of the spout bag suspension groove.

[0009] By adopting the above technical solution, when the nipple bag is transported, it is first hung in the nipple bag hanging groove, and then the nipple bag hanging groove filled with nipple bags is placed in the suspension cavity, so that the two ends of the nipple bag hanging groove are respectively located in the two limit grooves, so as to increase the stability of the nipple bag hanging groove, and avoid the nipple bag hanging groove falling from the frame due to the relative movement between the nipple bag hanging groove and the frame when the suction nozzle bag pre-installed transport device is pushed, thereby improving the transport efficiency of the nipple bag and ensuring the filling efficiency of the soy milk.

[0010] Optionally, the support member has a sliding groove, and the positioning member includes a sliding portion and a limiting portion, the sliding portion is slidably connected to the sliding groove, and the limiting groove is provided on the limiting portion.

[0011] By adopting the above technical solution, since the sliding part is slidably connected to the slide groove, the position of the positioning member can be adjusted to adjust the distance between two adjacent positioning members, so as to facilitate the placement and removal of the pacifier bag hanging groove, thereby further improving the transportation efficiency of the suction nozzle bag and further ensuring the filling efficiency of the soy milk.

[0012] Optionally, the support member includes a support section and an external section, the support section is arranged on the cavity wall of the suspension cavity, and the external section is arranged on the outside of the frame.

[0013] By adopting the above technical solution, since the external section is arranged on the outside of the frame, the positioning piece can be slid to the outside of the frame, so as to facilitate the placement of the pacifier bag hanging groove on the positioning piece and the removal of the pacifier bag hanging groove from the frame, thereby further improving the transportation efficiency of the pacifier bag and thereby improving the filling efficiency of the soy milk.

[0014] Optionally, the support member further includes a curved section, and the curved section is located between the support section and the external section.

[0015] By adopting the above technical solution, since the bending section is located between the supporting section and the external section, the sliding part can make a smooth transition between the supporting section and the external section to avoid the sliding part getting stuck between the supporting section and the external section, thereby ensuring the smoothness of the movement of the positioning part.

[0016] Optionally, a stop portion protruding from the wall of the sliding groove is provided at one end of the supporting section close to the external section, and the stop portion can move relative to the supporting section to avoid the sliding portion.

[0017] By adopting the above technical solution, since a stop portion protruding from the wall of the slide groove is provided at one end of the support section close to the external section, the stop portion can stop the sliding portion to avoid the situation where the positioning part moves to the external section under the action of shaking when the frame moves, thereby ensuring the stability of the pacifier bag hanging groove placed in the suspension cavity.

[0018] Optionally, the stopping portion is an elastic arc-shaped piece, and the elastic arc-shaped piece is fixedly connected to the supporting section on one side parallel to the sliding direction of the sliding portion.

[0019] By adopting the above technical solution, since the stop part is an elastic arc-shaped piece, when the sliding part slides in the slide groove, the pressure applied by the sliding part on the elastic arc-shaped piece can be increased by applying a larger thrust or pull force to the sliding part, so that the sliding part can pass over the elastic arc-shaped piece and slide smoothly along the slide groove, thereby ensuring that the sliding part can slide from the external section to the supporting section or from the supporting section to the external section.

[0020] Optionally, the support section is provided with an accommodating opening, and the elastic arc-shaped piece has a first end fixedly connected to the opening wall of the accommodating opening and a second end opposite to the first end, and a deformation gap is provided between the second end and the opening wall of the accommodating opening.

[0021] By adopting the above technical solution, since the first end of the elastic arc-shaped piece is fixedly connected to the mouth wall of the accommodating mouth, there is a deformation gap between the second end of the elastic piece and the mouth wall of the accommodating mouth, which enables the supporting sections to form avoidance with each other, so as to increase the avoidance space for the sliding part, thereby further ensuring the smoothness of the movement of the sliding part.

[0022] Optionally, the sliding portion includes a rolling wheel and a rotating shaft passing through the rolling wheel, and the limiting portion is connected to the rotating shaft.

[0023] By adopting the above technical solution, since the sliding part includes a rolling wheel and a rotating shaft passing through the rolling wheel, the friction force when the sliding part and the slide groove slide relative to each other can be reduced, thereby reducing the force required for the positioning part to slide, thereby further improving the smoothness of the movement of the positioning part and achieving the effect of facilitating the adjustment of the pacifier bag hanging groove placed on the positioning part.

[0024] Optionally, the rotating shaft is provided with a connecting rod, and the connecting rod extends out of the sliding groove and is connected to the limiting portion.

[0025] By adopting the above technical solution, since the limiting part is connected to the rotating shaft through the connecting rod, the structure of the limiting part is simplified, the difficulty of producing the limiting part is reduced, and the connection stability between the limiting part and the rotating shaft is increased.

[0026] Optionally, the limiting groove is provided with a stop wall located at the end of the nozzle bag hanging groove;

[0027] And / or, the frame has a stop rib located at the end of the nozzle bag hanging groove.

[0028] By adopting the above technical solution, since the limiting groove is provided with a stop wall located at the end of the nozzle bag hanging groove, after the nozzle bag hanging groove is placed on the positioning piece, the end of the nozzle bag hanging groove can cooperate with the stop wall to prevent the nozzle bag hanging groove from separating from the positioning piece in its own length direction, thereby increasing the stability of the nozzle bag hanging groove.

[0029] Since the frame has a stop rib located at the end of the nozzle bag hanging groove, the nozzle bag hanging groove is then placed between the positioning pieces, and the end of the nozzle bag hanging groove can cooperate with the stop rib to prevent the nozzle bag hanging groove from separating from the positioning piece in its own length direction, thereby increasing the stability of the nozzle bag hanging groove.

[0030] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0046] Reference Figures 1 to 4 The present application discloses a nozzle bag pre-positioning and transferring device, which includes a frame 1 and a walking wheel 2 arranged on the frame 1. The frame 1 has suspension cavities arranged in sequence from top to bottom. The opposite cavity walls of the suspension cavity are correspondingly provided with support members 3. The support members 3 are provided with positioning members 4. The positioning members 4 have a limiting groove 421 for accommodating the end of the nozzle bag hanging groove 5.

[0047] It can be understood that there are multiple running wheels 2, and the multiple running wheels 2 are respectively arranged at multiple corners of the bottom of the frame 1.

[0048] When the nipple bag is transported, it is first hung in the nipple bag hanging groove, and then the nipple bag hanging groove filled with nipple bags is placed in the suspension cavity, so that the two ends of the nipple bag hanging groove are respectively located in the two limit grooves 421, so as to increase the stability of the nipple bag hanging groove and avoid the nipple bag hanging groove falling from the frame 1 due to the relative movement between the nipple bag hanging groove and the frame 1 when the suction nozzle bag pre-installed transport device is pushed, thereby improving the transport efficiency of the nipple bag and ensuring the filling efficiency of the soy milk.

[0049] The present application does not make any specific limitation on the structure of the support member 3 and the positioning member 4. Preferably, refer to Figure 1 、 Figure 3 and Figure 4 The support member 3 has a sliding groove 311 , and the positioning member 4 includes a sliding portion 41 and a limiting portion 42 . The sliding portion 41 is slidably connected to the sliding groove 311 , and the limiting groove 421 is provided in the limiting portion 42 .

[0050] It can be understood that the support member 3 is a slide rail, and the slide rail has a T-shaped slide groove 311 along its length direction to increase the connection stability between the sliding part 41 and the slide groove 311.

[0051] Since the sliding portion 41 is slidably connected to the slide groove 311, the position of the positioning member 4 can be adjusted to adjust the distance between two adjacent positioning members 4, so as to facilitate the placement and removal of the pacifier bag hanging groove, thereby further improving the transportation efficiency of the suction nozzle bag and further ensuring the filling efficiency of the soy milk.

[0052] Preferably, the limiting portion 42 is a C-shaped structure, so that a limiting groove 421 is formed inside the limiting portion 42 to reduce the difficulty of producing the limiting portion 42 .

[0053] Further, refer to Figure 3 The support member 3 includes a support section 31 and an external section 32. The support section 31 is arranged on the cavity wall of the suspension cavity, and the external section 32 is arranged on the outside of the frame 1. The external section 32 extends downward from the support section 31, and then the positioning member 4 can be slid to the outside of the frame 1 to facilitate the placement of the pacifier bag hanging groove on the positioning member 4 and the removal of the pacifier bag hanging groove from the frame 1, so as to further improve the transportation efficiency of the pacifier bag and thereby improve the filling efficiency of the soy milk.

[0054] Further, refer to Figure 3 The support member 3 also includes a curved section 33, which is located between the support section 31 and the external section 32, so that the sliding portion 41 can smoothly transition between the support section 31 and the external section 32 to avoid the sliding portion 41 from getting stuck between the support section 31 and the external section 32, thereby ensuring the smooth movement of the positioning member 4.

[0055] Further, refer to Figure 3 A stopper 312 protruding from the wall of the sliding groove 311 is provided at one end of the support segment 31 close to the external segment 32 . The stopper 312 can move relative to the support segment 31 to avoid the sliding portion 41 .

[0056] Since the support section 31 is provided with a stop portion 312 protruding from the wall of the sliding groove 311 at one end close to the external section 32, the stop portion 312 can stop the sliding portion 41 to prevent the positioning member 4 from moving to the external section 32 due to the shaking when the frame 1 moves, thereby ensuring the stability of the pacifier bag hanging groove placed in the suspension cavity.

[0057] The present application does not make any specific limitation on the structure of the stopper 312. Preferably, refer to Figure 3 The stopper portion 312 is an elastic arc-shaped piece, and the elastic arc-shaped piece is fixedly connected to the support section 31 on one side parallel to the sliding direction of the sliding block.

[0058] Since the stop portion 312 is an elastic arc-shaped piece, when the sliding portion 41 slides in the slide groove 311, a larger thrust or pull can be applied to the sliding portion 41, thereby increasing the pressure applied by the sliding portion 41 on the elastic arc-shaped piece, so that the sliding portion 41 can pass over the elastic arc-shaped piece and slide smoothly along the slide groove 311, thereby ensuring that the sliding portion 41 can slide from the external section 32 to the support section 31 or from the support section 31 to the external section 32.

[0059] Further, refer to Figure 3 The support section 31 is provided with an accommodating opening 313. The elastic arc-shaped piece has a first end fixedly connected to the mouth wall of the accommodating opening 313 and a second end opposite to the first end. There is a deformation gap between the second end and the mouth wall of the accommodating opening 313, which enables the support section 31 to form an avoidance with the support section 31 to increase the avoidance space for the sliding part 41, thereby further ensuring the smoothness of the movement of the sliding part 41.

[0060] In other embodiments, the stop portion 312 may also be a ball spring structure provided inside the support section 31 , with at least a portion of the ball protruding from the slide groove 311 so as to be able to cooperate with the sliding portion 41 for stopping.

[0061] The present application does not specifically limit the structure of the sliding portion 41. Preferably, refer to Figure 3 and Figure 4The sliding portion 41 includes a rolling wheel 411 and a rotating shaft 412 passing through the rolling wheel 411. The limiting portion 42 is connected to the rotating shaft 412, which can reduce the friction when the sliding portion 41 and the slide groove 311 slide relative to each other, thereby reducing the force required for the positioning member 4 to slide, thereby further improving the smoothness of the movement of the positioning member 4 and achieving the effect of facilitating the adjustment of the pacifier bag hanging groove placed on the positioning member 4.

[0062] Further, refer to Figure 3 and Figure 4 The rotating shaft 412 is provided with a connecting rod 422, which extends out of the slide groove 311 and is connected to the limiting portion 42, thereby simplifying the structure of the limiting portion 42, reducing the production difficulty of the limiting portion 42, and increasing the connection stability between the limiting portion 42 and the rotating shaft 412.

[0063] Preferably, two rolling wheels 411 are provided at intervals, the rotating shaft 412 passes through the two rolling wheels 411 , and the connecting rod 422 is located between the two rolling wheels 411 to increase the connection stability between the sliding portion 41 and the sliding groove 311 .

[0064] In other embodiments, the sliding portion 41 may also be a block-shaped structure adapted to the sliding groove 311 .

[0065] In other embodiments, the support member 3 may also be a rod-shaped structure, the positioning member 4 is fixedly connected to the C-shaped structure of the support member 3, and the opening of the C-shaped structure is arranged upward.

[0066] In a preferred embodiment, the limiting groove 421 is provided with a stop wall located at the end of the nozzle bag hanging groove 5. After the nozzle bag hanging groove 5 is placed on the positioning piece 4, the end of the nozzle bag hanging groove 5 can cooperate with the stop wall to avoid the nozzle bag hanging groove 5 from separating from the positioning piece 4 in its own length direction, thereby increasing the stability of the nozzle bag hanging groove 5.

[0067] In a preferred embodiment, the frame 1 has a stop rib located at the end of the nozzle bag hanging groove 5, and then the nozzle bag hanging groove 5 is placed between the positioning members 4. The end of the nozzle bag hanging groove 5 can cooperate with the stop rib to prevent the nozzle bag hanging groove 5 from separating from the positioning member 4 in its own length direction, so as to increase the stability of the nozzle bag hanging groove 5; in addition, through the provision of the stop rib, the support member 3 can also be fixedly connected to the stop rib to increase the stability of the support member 3.
