Description

TECHNICAL FIELD

[0001] The utility model relates to paper bag packaging equipment technical field especially, a kind of material receiving mechanism for paper bag packaging equipment. BACKGROUND

[0002] Many foods on the existing market are filled with metal cans, and a thin cover body (also known as "thin cover") is arranged on the can opening of the metal can. In order to reduce the pollution of the cover body during transportation, a certain number of cover bodies are stacked and then transported to a paper bag packaging equipment after being processed, and the cover bodies are packaged with paper bags on the paper bag packaging equipment and then shipped.

[0003] For example, a Chinese invention patent application with the application number CN202011593099.2 (authorized publication number CN112660496B) discloses a paper bag packaging machine, which includes a machine frame, a storage bin, a suction cup assembly, a blocking piece, a guide assembly, a feeding device and a material receiving device. The storage bin is used to place the stacked paper bags. The feeding device is located upstream of the processing position, the suction cup assembly is located below the storage bin opening, the blocking piece is at least partially located on the moving path of the paper bag, and the guide assembly has two guide pieces. The paper bags in the storage bin are taken out by the suction cups in the suction cup assembly. The blocking piece contacts the extended edge of the paper bag when the paper bag moves downward, which realizes the vertical opening of the bag opening. The two guide pieces of the guide assembly act on the two side edges of the bag opening when the cover body moves to the state of being located in the guide channel, so that the two side edges of the bag opening are away from each other and are in an open state. The material receiving device includes a material receiving mechanism, which is arranged on the machine frame. The material receiving mechanism has a lifting assembly for driving the tray to move up and down relative to the workbench and a sliding assembly for driving the tray to slide between the packaging position and the material receiving position. The material receiving position has a storage groove formed by a partition plate for storing the packaged bag body. After the cover body enters the paper bag and the paper bag is completed, the tray is driven by the lifting assembly and the sliding assembly to move the paper bag containing the cover body to the storage groove of the material receiving position.

[0004] However, the material receiving device of the above-mentioned paper bag packaging machine still has some deficiencies. The material receiving mechanism needs to be driven upward by the lifting assembly to catch the paper bag first, and then the paper bag on the tray is transferred to the storage groove by cooperating with the sliding assembly. The action process of this material receiving mechanism is relatively complex, and there is a risk of falling off or falling during the transfer process of the paper bag, which cannot guarantee the stable unloading of the paper bag.

DETAILED DESCRIPTION

[0027] The utility model is further described in detail in combination with the embodiment of the drawings.

[0028] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0029] Figures 1-7 This invention illustrates a preferred embodiment of the paper bag packaging equipment and the receiving device for the paper bag packaging equipment. The paper bag packaging equipment generally includes a counting device 20, a feeding device 30, a packaging device 40, and a receiving device. The counting device 20 is used to quantitatively count the caps b during the feeding process. After counting, a stack of caps b is pushed to the packaging position 100 by the feeding device. The packaging device is used to deliver the stacked caps b into the paper bag a located at the packaging position 100 and seal the paper bag a. After sealing, the paper bag a is unloaded by the receiving mechanism. The counting device of the paper bag packaging equipment can employ conventional cap b counting devices such as infrared counting sensors, as similarly disclosed in application CN202322600194.6, "A Counting and Conveying Device for Caps b". The feeding device and packaging device of the paper bag packaging equipment can also adopt existing technologies, such as the corresponding device or equipment in the Chinese invention patent application "A Paper Bag Packaging Machine" with application number CN202011593099.2 (authorization announcement number: CN112660496B), which will not be elaborated further.

[0030] The paper bag a used to hold the lid b is also basically long and narrow. When the paper bag a is fully opened or stretched, its cross-section is basically circular, with the inner diameter slightly larger than the outer diameter of the lid b. This ensures that a stack of lids b can be smoothly put into the paper bag a, and makes the paper bag a more compact as a whole after the lids b are put in, without any looseness or wrinkles.

[0031] The receiving device for paper bag packaging equipment is used to receive the caps (b) after the paper bags (a) have been packaged, and to unload them. Specifically, the receiving device includes a support rod assembly 80, a unloading device, and a bracket device.

[0032] The support rod assembly 80 is arranged at a position where the packaging station 100 of the paper bag packaging device is located, and the paper bag a can be transferred to the support rod assembly 80 and the paper bag a packaging of the cover b is completed on the support rod assembly 80. Specifically, the support rod assembly 80 of the embodiment includes two support rods 81 arranged side by side and spaced apart, and the extension direction of the two support rods 81 is consistent with the length direction of the paper bag a. The two support rods 81 can be driven by a rotary driving mechanism to move close to each other or move away from each other, and when the two support rods 81 move close to each other to a set position, a support state of forming upward support to the paper bag a can be maintained. It can be understood that in the support state, the spacing between the two support rods 81 is smaller than the outer diameter of the cover b, so that the paper bag a with the cover b can be placed thereon. After the paper bag a with the cover b is packaged, the two support rods 81 move away from each other, and the paper bag a falls down from between the two support rods 81 to realize the material falling.

[0033] Referring to Figure 3 , the support rod assembly 80 further includes two rotating shafts 82 arranged side by side and each capable of rotating about its own axis, and a first rotary driving mechanism 83 (i.e. a driving member) for driving the two rotating shafts 82 to rotate. The two support rods 81 are parallel to the rotating shafts 82 and are respectively connected to the corresponding rotating shafts 82, and the support rod 81 and the rotating shaft 82 are connected through a plurality of connecting rods 84 arranged in the length direction of the support rod 81 in sequence. The first rotary driving mechanism 83 includes two rotary cylinders, and the power output shafts of the two rotary cylinders are respectively connected to the two rotating shafts 82 through a gear transmission mechanism, a belt transmission mechanism or a chain transmission mechanism, so as to drive the two rotating shafts 82 to rotate in opposite directions, thereby realizing the mutual approach or mutual separation of the two support rods 81.

[0034] Referring to Figure 5The unloading device is located below the supporting rod and comprises an unloading driving mechanism and a roller assembly capable of being driven by the unloading driving mechanism to rotate cyclically. Generally, the roller assembly can adopt a conventional roller feeder in the prior art. Specifically, the unloading driving mechanism comprises an unloading driving motor 85, and the roller assembly comprises two groups of chain wheel mechanisms arranged side by side and a plurality of rolling cylinders 861 arranged in sequence and at intervals in the feeding direction, and the two groups of chain wheel mechanisms are arranged at both ends of the length direction of each rolling cylinder 861. Each group of chain wheel mechanisms comprises two or more chain wheels 862 arranged in the conveying direction and a transmission chain 863 wound on the chain wheels 862. The two ends of each rolling cylinder 861 are connected to the transmission chains 863 of the two groups of chain wheel mechanisms respectively and are driven to move by the transmission chains 863. The length direction of the rolling cylinder 861 is consistent with the length direction of the paper bag a with the cover b, and the spacing between the adjacent two rolling cylinders 861 is smaller than the outer diameter of the cover b, so that the paper bag a with the cover b can be supported by the adjacent two rolling cylinders 861 after falling.

[0035] Referring to Figures 4-7 The bracket device comprises a bracket driving mechanism and a bracket assembly capable of being driven by the bracket driving mechanism to move up and down. Specifically, a first fixed frame 87 is arranged on the rack 10 below the roller assembly. The bracket driving mechanism comprises a first lifting cylinder 891 arranged on the first fixed frame 87. The bracket assembly is long strip-shaped, and the length direction of the bracket assembly is consistent with the extension direction of the rolling cylinder 861. The middle part of the bracket assembly is connected to the power output end of the first lifting cylinder 891, and the bracket assembly can move reciprocatingly in the up-down direction under the driving of the first lifting cylinder 891. Specifically, the width dimension of the bracket assembly is smaller than the gap between the adjacent two rolling cylinders 861, and the bracket assembly can pass through the gap between the adjacent two rolling cylinders 861 of the unloading device upward and approach the supporting rod 81, so as to receive the paper bag a falling from the supporting rod 81. After the paper bag a falls on the bracket assembly, the bracket assembly is driven downward by the first lifting cylinder 891. During the downward movement, the bracket assembly can pass through the gap between the adjacent two rolling cylinders 861 of the unloading device, and when the bracket assembly continues to move downward after passing through the gap between the adjacent two rolling cylinders 861 of the unloading device, the paper bag a with the cover b falls on the two rolling cylinders 861. After the paper bag a falls on the roller assembly, the cyclic rotation of the roller assembly drives the paper bag a to move to the corresponding material receiving position, so as to realize the transfer and material receiving of the paper bag a.

[0036] In order to adapt to the situation that the supporting rod 81 and the paper bag a placed thereon are arranged in an inclined state (relative to the horizontal direction) and to more stably receive the paper bag a, the bracket assembly comprises a bracket body 88 and a bracket support frame 880 located below the bracket body 88, both of which are long strips and have the same extending direction. The power output end of a first lifting cylinder 891 is connected to the middle part of the bracket support frame 880. The first end or the position adjacent to the first end of the bracket support frame 880 is rotationally connected to the bracket body 88 through a left-right extending pin shaft. The second end or the position adjacent to the second end of the bracket support frame 880 is provided with a third lifting cylinder 892, the power output end of which moves in the up-down direction and is also rotationally connected to the bracket body 88 through a left-right extending pin shaft. In addition, a sliding groove 883 extending along the length direction of the bracket body 88 is formed in the bracket body 88, and the pin shaft is slidingly limited in the sliding groove 883. The first end of the bracket support frame 880 corresponds to the bag opening of the paper bag a, and the second end corresponds to the bottom of the paper bag a. When receiving the paper bag a, the bracket assembly moves upwards through the gap between the adjacent two rolling cylinders 861 of the discharging device to the position adjacent to the lower part of the supporting rod 81, and then, under the driving of the third lifting cylinder 892, the second end of the bracket body 88 is upwardly deflected relative to the bracket support frame 880 until the inclined direction thereof is basically consistent with the inclined direction of the supporting rod 81. Since the inclined directions of the bracket body 88 and the supporting rod 81 are consistent, the paper bag a is not easy to fall off from the bracket body 88 after falling onto the bracket body 88, thereby ensuring the stability of receiving the paper bag a.

[0037] After the paper bag a falls onto the bracket assembly, the bracket assembly is driven downwardly by the first lifting cylinder 891. During the downward movement, the bracket assembly can pass through the gap between the adjacent two rolling cylinders 861 of the discharging device, and when continuously moving downwardly after passing through the gap, the paper bag a with the cover b falls onto the two rolling cylinders 861. After the paper bag a falls onto the rolling cylinder assembly, the rolling cylinder assembly is cyclically rotated to drive the paper bag a to move to the corresponding receiving position, thereby achieving the transfer and receiving of the paper bag a.

[0038] The bottom of the bracket support frame 880 is further provided with at least two downwardly extending guide rods 881, and the first fixing frame 87 is provided with guide holes through which the guide rods 881 pass. Specifically, the guide rods 881 of the embodiment are two, and the two guide rods 881 are respectively located on the two sides of the first lifting cylinder 891. After the two guide rods 881 are arranged, the stability of the up-down movement of the bracket assembly can be effectively ensured. The bracket main body 88 is defined with an open-top mounting groove, and the mounting groove is provided with a magnet 882 for attracting the paper bag a provided with the cover b. After the paper bag a provided with the cover b falls from the support rod to the bracket main body 88, the paper bag a can be firmly attracted by the magnet 882, so that the paper bag a is prevented from falling off the bracket when falling onto the bracket.
