Description

Technical Field

[0001] The present invention relates to the technical field of frozen food packaging, and in particular to a packaging device for pie boxing. Background Art

[0002] After frozen pies and other frozen foods are mass-produced and frozen by food machinery, they need to be boxed. This process is currently mainly carried out manually, which has the disadvantages of low efficiency, high manual labor intensity, and high labor costs.

[0003] The Chinese invention patent with the publication number CN112758423A discloses a food processing automatic collection device, a food processing system, and a food processing automatic collection method. A food processing automatic collection device is arranged below the food blank forming device of a stuffing machine to drive the tray to move horizontally or vertically, so as to pick up food blanks such as buns, balls, and pies processed by the stuffing machine in three-dimensional space movement, and can replace manual labor for boxing the food blanks. This solution achieves the purpose of replacing manual boxing and improving efficiency to a certain extent, but this solution needs to rely on the movement of the tray to pick up the food blanks. Each concave cavity of the tray corresponds to a food blank. During collection, only one concave cavity can be used for food blank collection each time an action is performed, and the working efficiency still cannot be effectively improved.

[0035] In order to make the technical objectives, technical solutions and beneficial effects of the present invention clearer, the following further describes the technical solutions of the present invention with reference to the Figures 1-3 accompanying drawings and specific embodiments.

[0036] An embodiment of a packaging device for cartoning pies:

[0037] A packaging device for pie boxing includes a first diversion area 1, a second diversion area 2, and a boxing area 3;

[0038] The first diversion area 1 includes a first frame, a first power mechanism 12, and a first transmission mechanism. The first power mechanism 12 can be a reduction motor. The first transmission mechanism includes a driving roller 13, a head drum 14, a tail drum 15, and a first conveyor belt 16. The head drum 14 and the tail drum 15 are located in the same horizontal plane and are arranged in parallel. The head drum 14 and the tail drum 15 are respectively rotationally connected to both ends of the first frame through drum shafts. The driving roller 13 is located below the first frame. The first power mechanism 12 drives the driving roller 13 to rotate, and the first conveyor belt 16 is driven by the driving roller 13, the head drum 14, and the tail drum 15;

[0039] The first frame includes a rectangular frame 111 and a diversion plate 112 that divides the first diversion area 1 into multiple flow channels. The rectangular frame 111 is horizontally arranged, the diversion plate 112 is vertically arranged. A gantry bracket 113 is straddled on the rectangular frame 111. The diversion plate 112 is fixed under the gantry bracket 113, and the extending direction of the diversion plate 112 is perpendicular to the gantry bracket 113. The gap between the diversion plate 112 and the first conveyor belt 16 is smaller than the thickness of the pie;

[0040] The number of the diversion plates 112 is denoted as n, n is an integer and greater than or equal to 1. The number of flow channels for transporting pies is n + 1. Taking the flow direction of the pies in the first diversion area 1 as from right to left;

[0041] The second diversion area 2 includes a second frame, a second power mechanism, and a second transmission mechanism. The second frame includes multiple diversion flow channel frames 21 arranged side by side. The number of the diversion flow channel frames 21 is n + 1. The diversion flow channel frames 21 extend along the left - right horizontal direction, and the length of each diversion flow channel frame 21 increases sequentially from inside to outside. The second power mechanism includes a driving motor 22, a sprocket transmission mechanism, and a diversion driving shaft 23. The diversion driving shaft 23 penetrates through each diversion flow channel frame 21 and is rotationally connected to each diversion flow channel frame 21. The driving motor 22 drives the diversion driving shaft 23 to rotate through the sprocket transmission mechanism;

[0042] Each diversion flow channel frame 21 corresponds to a set of the second transmission mechanism. Each set of the second transmission mechanism includes a diversion driving wheel 24, a diversion driven wheel 25, and a second conveyor belt 26. The diversion driving wheel 24 and the diversion driven wheel 25 are located in the same horizontal plane and are arranged in parallel at both ends of the corresponding diversion flow channel frame 21. Each diversion driving wheel 24 is rotationally connected to the diversion flow channel frame 21 through the diversion driving shaft 23. Each diversion driven wheel 25 is rotationally connected to the diversion flow channel frame 21 through a diversion driven shaft. The second conveyor belt 26 is driven by the diversion driving wheel 24 and the diversion driven wheel 25;

[0043] On both sides of the second rack, there are second mounting side plates 211 fixed respectively. A second guiding roller 27 is rotatably connected between the two second mounting side plates 211. The second guiding roller 27 is arranged adjacent to the shunting driving wheel 24. The second guiding roller 27 can increase the contact surface between the second conveyor belt 26 and the shunting driving wheel 24 to ensure the transmission accuracy.

[0044] The cartoning area 3 includes a third rack, a third power mechanism 33 and a third transmission mechanism. The third rack includes a plurality of cartoning flow channel racks 31 arranged side by side. The number of cartoning flow channel racks 31 is n + 1. The cartoning flow channel racks 31 are perpendicular to the shunting flow channel racks 21. Each cartoning flow channel rack 31 is respectively equipped with a corresponding third power mechanism 33 and a third transmission mechanism to realize independent speed regulation of each flow channel in the cartoning area 3. The third power mechanism 33 can select a reduction motor. The third transmission mechanism includes a cartoning driving wheel 34, a cartoning driven wheel 35 and a third conveyor belt 36. The cartoning driving wheel 34 is located below the cartoning flow channel rack 31. There are two cartoning driven wheels 35 which are located in the same horizontal plane and are arranged in parallel at both ends of the corresponding cartoning flow channel rack 31. Each cartoning driving wheel 34 is rotatably connected to the cartoning flow channel rack 31 through a cartoning driving shaft. Each cartoning driven wheel 35 is rotatably connected to the cartoning flow channel rack 31 through a cartoning driven shaft. The third power mechanism 33 independently drives the corresponding cartoning driving wheel 34 to rotate. Each third conveyor belt 36 is driven by its corresponding cartoning driving wheel 34 and cartoning driven wheel 35 respectively. A plurality of partition plates 37 are fixedly arranged vertically at intervals on the surface of each third conveyor belt 36.

[0045] The plane where the first conveyor belt 16 is located is slightly higher than the plane where the second conveyor belt 26 is located, and the first conveyor belt 16 and the second conveyor belt 26 are set with differential speeds. The plane where the second conveyor belt 26 is located is higher than the plane where the third conveyor belt 36 is located.

[0046] The flow channels in the first shunting area 1 correspond to the flow channels in the second shunting area 2 one by one and have the same flow direction. The flow channels in the second shunting area 2 correspond to the flow channels in the cartoning area 3 one by one and are perpendicular to each other. This layout can effectively utilize the space.

[0047] The second conveyor belt 26 and the third conveyor belt 36 can select synchronous belts. Their belt bodies have teeth, with relatively high transmission accuracy, not easy to deviate, and accurate positioning.

[0048] When this embodiment is in use, it is mainly divided into three major steps, which are in turn:

[0049] The first step is to roughly shunt the pies from the previous process through the first shunting area 1.

[0050] In the second step, the pies are spaced apart by the second diversion area 2, that is, by adjusting the speed of the second conveyor belt 26 to form a differential speed with the first conveyor belt 16, so that the pies entering the second diversion area 2 from the first diversion area 1 are spaced apart, realizing the separation between pies in each flow channel, so as to facilitate counting and / or intermittent entry into the boxing area 3;

[0051] In the third step, a material box for loading pies is placed between the partition plates 37 of each third conveyor belt 36 in the boxing area 3. The pies falling from the flow channels in the second diversion area 2 are boxed by the boxing area 3, and the speed of each flow channel in the boxing area 3 can be adjusted independently.

[0052] Specifically, the inlet position of the first diversion area 1 is docked with the discharge position of the previous process, so that the pies frozen and formed by the previous process through a freezing device (such as a spiral tunnel freezer) enter the first diversion area 1 for rough separation. In this embodiment, the number of diversion plates 112 is three, and the number of flow channels for conveying pies is four. The diversion plates 112 can divide the pie incoming material into four flow channels; in the second step, the pies in each flow channel are spaced apart. However, since the number of pies divided into each flow channel in the first diversion area 1 is different, there may be different pie intervals between different flow channels in the second diversion area 2, resulting in different incoming speeds of the boxing area 3. By independently adjusting the speed of each flow channel in the boxing area 3, the belt speed of each flow channel in the boxing area 3 is respectively matched with the corresponding flow channel in the second diversion area 2, realizing independent boxing for each flow channel; when boxing, the number of pies loaded in each material box is greater than or equal to 1, and the pause duration of each third conveyor belt 36 in the boxing area 3 is adjusted according to the number of pies to be loaded into the same material box as required.

[0053] The different speeds of each flow channel in the boxing area 3 also facilitate separately picking up the material boxes that have been boxed.

[0054] Furthermore, as one of the embodiments of the present invention, first mounting side plates 114 are respectively fixed on both sides of the first rack. The driving roller 13 passes through the first mounting side plate 114 and is rotatably connected to the output shaft of the first power mechanism 12; an installation rod 115 is also fixed on the first mounting side plate 114, and a torsion arm 116 is fixed between the installation rod 115 and the first power mechanism 12. The torsion arm 116 and the installation rod 115 are equivalent to the installation bracket of the first power mechanism 12. This structure saves more space compared with the installation bracket.

[0055] Further, as one embodiment of the present invention, the first transmission mechanism further includes a tension adjusting roller 17 and a first guiding roller 18. The tension adjusting roller 17 and the first guiding roller 18 are respectively arranged above both sides of the driving roller 13, and are respectively rotatably connected to the first mounting side plate 114 through a roller shaft. The tension of the tension adjusting roller 17 is adjusted through a tension adjusting assembly. In this embodiment, the roller shafts of the tension adjusting roller 17 and the first guiding roller 18 are respectively fixedly connected to the first mounting side plate 114. The tension adjusting roller 17 and the first guiding roller 18 are respectively rotatably connected to their respective roller shafts, and the position of the roller shaft of the tension adjusting roller 17 is adjustable.

[0056] Taking this embodiment as an example, as Figure 3 shown, the tension adjusting assembly includes a tension support 192 and a first adjusting screw 193. A first tension adjusting hole 191 is formed on the first mounting side plate 114. The end of the roller shaft of the tension adjusting roller 17 extends out of the first tension adjusting hole 191. The first tension adjusting hole 191 is of a long hole structure. The tension support 192 is fixed on the first mounting side plate 114. The first adjusting screw 193 is threadedly connected to the tension support 192, and the first adjusting screw 193 is perpendicularly arranged with respect to the roller shaft. During tension adjustment, the first adjusting screw 193 pushes the roller shaft of the tension adjusting roller 17 to move along the first tension adjusting hole 191.

[0057] Further, as one embodiment of the present invention, in the second diversion area 2, a tension adjusting frame for adjusting the tension of the second transmission mechanism is fixed at one end of each diversion flow channel frame 21 close to the diversion driven wheel 25.

[0058] Specifically, in this embodiment, as Figure 3 shown, the tension adjusting frame includes two symmetrically arranged tension adjusting plates 213. A second tension adjusting hole 214 is formed on the tension adjusting plate 213. The second tension adjusting hole 214 is of a long hole structure. A second adjusting screw 215 is inserted through and threadedly connected to the tension adjusting plate 213. The other end of the second adjusting screw 215 is perpendicularly threadedly connected to the diversion driven shaft. The other end of the second adjusting screw 215 can penetrate out of the diversion driven shaft and a limit block for preventing the second adjusting screw 215 from disengaging from the diversion driven shaft is fixed. When adjusting the tension of the diversion driven wheel 25, by turning the second adjusting screw 215, the diversion driven shaft can be pushed or pulled to move in the second tension adjusting hole 214, thereby adjusting the tension.

[0059] Further, as one embodiment of the present invention, in the cartoning area 3, wall plates 32 are installed on both sides of the third conveyor belt 36 on each cartoning flow channel frame 31. The third power mechanism 33 is installed below the wall plates 32.

[0060] Further, as one embodiment of the present invention, the third transmission mechanism further includes a tensioning wheel assembly. The tensioning wheel assembly includes two oppositely arranged tensioning wheels 38. The two tensioning wheels 38 are respectively rotatably connected to the two wall plates 32 through tensioning wheel 38 shafts. The distance between the two tensioning wheels 38 is greater than the width of the surface partition 37 of the third conveyor belt 36. The tensioning degree of the tensioning wheel 38 is adjusted through a tensioning adjustment assembly.

[0061] In this embodiment, the structure adopted by the tensioning adjustment assembly is the same as the tensioning adjustment method of the tensioning adjustment roller 17 in the first transmission mechanism.

[0062] Further, as one embodiment of the present invention, a first horizontal support plate for assisting in supporting the first conveyor belt 16 is fixed inside the rectangular frame 111 of the first rack. A second horizontal support plate for assisting in supporting the second conveyor belt 26 is respectively fixed in each shunt channel rack 21 of the second rack; a third horizontal support plate for assisting in supporting the third conveyor belt 36 is respectively fixed in each cartoning channel rack 31 of the third rack.

[0063] Further, as one embodiment of the present invention, in the second shunt area 2, nylon guard plates 212 are detachably fixed on both sides of the second conveyor belt 26 on each shunt channel rack 21 of the second rack. The nylon guard plates 212 are higher than the plane where the second conveyor belt 26 is located, which can prevent being knocked and damaged by the shunted pies.

[0064] Further, as one embodiment of the present invention, a counting sensor is installed above one end of each shunt channel rack 21 close to the shunt driven wheel 25 for counting the pies, which is not shown in the figure.

[0065] Further, as one embodiment of the present invention, the first rack, the second rack, and the third rack are respectively supported by legs 4. Adjustable feet 5 are installed at the bottoms of the legs 4. When the flatness of the ground where they are located cannot be guaranteed, the height of the legs 4 is finely adjusted through the adjustable feet 5. The adjustable feet 5 are prior art and will not be described in detail here.

[0066] The above embodiments do not impose any formal restrictions on the shape, material, structure, etc. of the present invention. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention all belong to the protection scope of the technical solution of the present invention.
