Detailed Description

The invention is described in detail below with reference to the figures and examples.

Fig. 1 to 8 show an embodiment of a paper bowl and paper cup production line according to the present invention, which includes a forming machine 1, winding a fan-shaped paper sheet into a cylindrical shape, and then joining the cylindrical shape with a round bottom to form a finished paper bowl or paper cup, wherein a bar code or two-dimensional code capable of being recognized is printed on the printed pattern on the outer wall of the paper cup or paper bowl, so as to facilitate subsequent material collection during sorting. After the forming machine 1 finishes processing paper bowls or paper cups, the paper bowls or paper cups are collected into a strip by a collecting device on the forming machine 1 and placed on a product arranging platform, a collecting groove 121 is arranged at the edge of the product arranging platform, products fall into a collecting conveying belt 11 after passing through the collecting groove 121, the products are carried for subsequent processing, in order to enable the efficiency of subsequent processing equipment to be exerted to the maximum, a plurality of forming machines 1 are arranged at the position of the collecting conveying belt 11, the forming machines 1 can produce paper bowls or paper cups with the same model and can also produce paper bowls or paper cups with different models, in order to facilitate subsequent description, the forming machines 1 in the embodiment of the invention are provided with four products with different models, namely, No. 1, No. 2, No. 3 and No. 4, and simultaneously two-dimensional codes or bar codes on the 4 products are different from each other, and when the products enter the subsequent platform, if the model number of the product is not directly indicated separately, it is important that all models are common.

As shown in fig. 1 and fig. 3 to 5, when a product is placed on the platform, the product rolls from the platform into the collecting tank 121, at this time, the first detection unit 125 arranged in the collecting tank 121 detects that the product enters the collecting tank 121, the shielding plate 122 is arranged at the bottom of the collecting tank 121 to shield the product from falling, the shielding plate 122 is driven by the first air cylinder 124, and the shielding plate 122 and the first air cylinder 124 form the blanking mechanism 12, so that the blanking mechanism is switched between a blocking state and an opening state. When the first detecting unit 125 detects that the product enters the collecting tank 121, the first cylinder 124 enters a standby state at this time.

When the product is detected to enter the collecting tank 121, the pressing mechanism arranged in the collecting tank 121 is started, the pressing mechanism comprises a second cylinder 123 arranged at one end of the collecting tank 121 and a pressing plate 127 arranged on the second cylinder 123, and when the pressing plate 127 is matched with the end wall of the collecting tank 121, the originally relatively loose product is pressed tightly by the end wall of the collecting tank 121 and the pressing plate 127, so that the product is more convenient to process in the subsequent process and cannot be scattered easily. While the second cylinder 123 retracts the cylinder rod after the extrusion is completed so that the platen 127 is returned to its original position in preparation for the next compression.

The first detection unit 125 can be arranged as a pressure sensor, and is arranged at the inlet or the bottom of the collecting tank 121, and when the product is pressed to the sensor position, the product is detected to enter the collecting tank 121, so that the second cylinder 123 is opened, and the purposes of detecting the product and controlling the second cylinder 123 are achieved. In addition, the first detecting unit 125 can be configured as an infrared sensor, which generally has a collecting end and an emitting end, which need to be opposite to each other. The inner wall of the collecting groove 121 can be directly arranged at two ends of the collecting groove 121, and at the moment, in order to facilitate transmission of infrared rays, a through hole is formed in the pressing plate 127, so that the infrared rays can pass through the through hole. And when the product got into and collects the inslot 121, sheltered from the transmission of infrared ray, reach the purpose that detects, open the second cylinder 123 simultaneously and compress tightly.

After the second cylinder 123 completes the pressing, the first cylinder 124 is on standby at this time. Set up collection conveyer belt 11 below collecting vat 121, collect conveyer belt 11 and collect the product that a plurality of make-up machines 1 produced, consequently, at the in-process of collecting, let produce easily between product and the product and pile up, at this moment, be unfavorable for the follow-up arrangement to the product, also can directly fall out collection conveyer belt 11. On this basis, a second detection unit 126 and a third detection unit 128 are provided on the collection conveyor belt 11, respectively placed at the two ends corresponding to the collection gutter 121. The second detection unit 126 detects the entry of the product into the bottom end of the collection trough 121 of the collection conveyor 11, at which point the first cylinder 124 is switched off, leaving the first cylinder 124 in a closed state. When the end of the product passes the third detection unit 128, the first cylinder 124 is opened to let the product in the collection trough 121 fall into the collection conveyor belt 11. At this time, the second detection unit 126 and the third detection unit 128 adopt infrared sensors, and two parts of the sensors are respectively arranged on two sides of the collection conveyor belt 11, so that the detection control purpose is achieved by blocking signals through the passing of products.

As shown in fig. 1 to 5, two shielding plates 122 are provided and hinged to two side plates at the bottom of the collecting tank 121, respectively, the first cylinder 124 is fixed on the collecting tank 121, two connecting rods 129 are provided at the end of the cylinder rod of the first cylinder 124, one end of each of the two connecting rods 129 is hinged to the cylinder rod, and the other end is hinged to the shielding plate 122. Thus, when the first cylinder 124 pushes, the end of the connecting rod 129 moves towards the shutter 122, and at the same time, because the length of the shutter 122 and the connecting rod 129 is fixed and hinged, the other two ends of the connecting rod 129 will be opened outwards, so that the two shutters 122 are opened, and the product falls from the collecting trough 121 to the collecting conveyor 11. In order to facilitate the hinge connection of link 129 and shutter 122, shutter 122 is provided with a rod, and the end of link 129 is fitted over the rod and hinged thereto.

As shown in fig. 1-5, after the product enters the collecting conveyor belt 11, the collecting conveyor belt 11 conveys the product to the next line, and for the classification boxing line 3, each group of products is firstly conveyed into the automatic packaging machine 2 for plastic film wrapping and simultaneously sealed, and then passes through the shrinking device 21 to shrink the plastic film to the size similar to the product, so that the boxing is more convenient. The shrinking device 21 generally employs an oven to shrink, and the plastic bag is shrunk by high temperature. Meanwhile, in the shrinking process, high-frequency rays can be adopted, sterilization can be simultaneously carried out in the shrinking process, and the paper cup is cleaner.

After the packaging is finished, the classified collection and boxing process is carried out, and after the packaging is finished, the two-dimensional codes or the bar codes in the surface patterns of the products are identified through scanning by a code scanning gun. And after scanning, transmitting the information obtained by scanning to a controller for processing. A plurality of guide chutes 36 are provided at one side of the sorting conveyor 31, and a third air cylinder 34 is provided at the other side of the guide chute 36. The cylinder body of the third cylinder 34 is fixed on the frame 35 of the sorting conveyor 31, and a pushing block 33 is hinged on the frame 35, the cylinder rod of the third cylinder 34 is hinged with the pushing block 33, and the third cylinder 34 is connected with the controller. The controller compares the information scanned by the scanning gun 32, and transmits a corresponding signal to the corresponding third cylinder 34 to start the third cylinder, so that the pushing block 33 pushes the product into the material guide chute 36 directly and the product enters the collecting box arranged below the material guide chute 36 to be collected. The third cylinder 34 and the chute 36 are also individually numbered in different categories for different models of products to be processed by the molding machine 1.

As shown in fig. 1, 6, and 7, in the above-mentioned material pushing process, after a signal is detected, a corresponding line is selected to output a start signal, and meanwhile, if the signal is directly output, a pushing action is generated when a product does not reach a designated position yet, so that the purpose of accurately classifying the material to be pushed cannot be achieved. In order to make the product and the device correspond, the signal transmission should be carried out with time delay. The third cylinder 34 and the detected position of the code scanning gun are fixed, meanwhile, the speed of the conveyor belt can be controlled, when the detected product is No. 1, the controller calls the data of the No. 1 material guide chute 36 and the detected position, calls the speed of the conveyor belt at the moment, calculates the delay time, and sends the delay time into the delayer. When the time is up, the controller transmits a signal for activating the third cylinder 34 to the position of the guide chute 1 36, and the product produced by the forming machine No. 1 passing through the position is pushed out to the guide chute 36 for packaging. Meanwhile, a bar code or a two-dimensional code which is printed with the product No. 1 is printed on the packaging box. When the product No. 2, the product No. 3 or the product No. 4 is detected, the controller adopts the same signal transmission mode as the signal transmission mode No. 1.

As shown in fig. 1, 6 and 7, in the process of scanning codes by the code scanning gun on the sorting conveyor belt 31, the two-dimensional codes or the bar codes are not scanned by the code scanning gun, so that the products cannot be identified when passing through the code scanning gun. Therefore, the scanning mode of 360 degrees needs to be arranged on the code scanning gun, so that each product cannot be missed. Therefore, at least 3 code scanning guns are arranged at the scanning position and are uniformly distributed around the scanning position at equal intervals, so that all scanning areas can be covered, and missing scanning is prevented. In order to ensure that the scanned information is more accurate, the invention is provided with 4 code scanning guns.

As shown in fig. 1, 6 and 7, in the process of guiding the material, the material guiding chute 36 may cause that some products are symmetrical due to the left and right forces during the rolling process, and the products are changed from originally horizontal to vertical when finally falling, which is that the bagging is found out to be disordered, or the manual arrangement is needed, which is not beneficial to the automation of the production. Therefore, the baffle plate 37 is arranged in the guide chute 36, when the products fall to a half, the products are straightened through the baffle plate, meanwhile, a plurality of products are collected through the baffle plate and fall simultaneously, at the moment, the limiting effect exists between each product and the corresponding product, the products are always in a transverse state in the falling process, at the moment, the products finally fall into the collecting box in the same order, and automatic box loading is completed.

The driving of the blocking plate 37 can adopt a driving air cylinder 38, and the blocking plate 37 is pulled upwards by the pulling of the air cylinder, so that the material guide chute 36 is opened. Mounting brackets are provided on both side plates of the material guide chute 36, on which the driving cylinder 38 is placed, and the cylinder rod is connected with the blocking plate 37. The control of the driving cylinder 38 may be controlled by a pressure sensor provided at the bottom of the blocking plate 37 or the guide chute 36, and when the pressure reaches a preset value, the pressure sensor outputs an activation signal and controls the driving cylinder 38 to open the blocking plate 37 to discharge the product. The pressure is recovered, at this time, the driving cylinder 38 lowers the blocking plate 37 again, and the material blocking of the next round is carried out. The pressure sensor can also be replaced by an infrared sensor which is arranged on two side plates of the material guide chute 36 to detect the height of the stacked products so as to achieve the purpose of detection.

In addition, the driving cylinder 38 can be controlled by a counter, the counter can count by infrared rays or by a pressure sensor, or the number of the third cylinder 34 can be counted, and when a certain number is reached, a starting signal is sent to control the driving cylinder 38 to pull up the blocking plate 37, so that the purpose of discharging is achieved. Wherein the infrared sensor can be arranged at the position where the material enters the material guide chute 36, and the counting is carried out by the times of the shielding signals. Similarly, a pressure sensor is also provided at the point of entry into chute 36 to count the pressure generated by the material being rolled over, but the pressure sensor count is affected by the weight of the material and is therefore not generally used.

After the boxing, the boxing is required to be sent to the box sealing machine 45 for post-finishing procedures such as box sealing and the like, so that the subsequent finishing line is entered, the finishing line is conveyed by the aid of the finishing conveyor belt 4, and the box sealing machine 45 is placed on the finishing conveyor belt 4 to realize functions of box sealing and conveying. During subsequent warehousing, the warehouse is conveyed to the warehouse through the sorting conveying belt 4, and the warehouse is divided into a No. 1 warehouse, a No. 2 warehouse, a No. 3 warehouse and a No. 4 warehouse which correspond to the products. Because the collecting box is a regular cube or cuboid structure, the collecting box can not be scanned in the conveying process, the collecting conveyor belt 11 is directly arranged on one side, a plurality of sub conveyor belts 41 are arranged on the same side of the collecting conveyor belt, the identification pushing device 42 opposite to the collecting conveyor belts is arranged, the identification pushing device 42 comprises a scanner 421 and a pushing cylinder 422 matched with the scanner 421, when the collecting box is conveyed to a specified position, scanning checking is carried out, when checking is accurate, the pushing cylinder 422 is started, the collecting box is pushed to the sub conveyor belts 41, and the collecting box is conveyed and stacked to be put in storage through a manipulator arranged at the end parts of the sub conveyor belts 41. The robot has a bar code or two-dimensional code that identifies the collection bin and stacks the same category of products into the same area. Generally, such a robot can recognize more than 4 kinds of bar codes and stack them correspondingly to one area.

The control circuits of the scanning gun and the third cylinder in the identification pushing device and the classification packing line are the same, the control circuits of the scanning gun and the third cylinder in the identification pushing device and the classification packing line respectively identify information in a bar code or a two-dimensional code through an identification unit, namely a two-dimensional code or a bar code identifier, then activate the identified information through a chip of the identification bar code or the two-dimensional code, and then output corresponding signals to control the corresponding cylinders to push, so that the classification purpose is achieved. The system for identifying and controlling is the same as the control system of a supermarket or a temporary storage cabinet, and in order to enable the time to be the same as that of the articles on the conveyor belt, a delayer is connected in series with a control switch of a third air cylinder or a pushing air cylinder, and the materials are enabled to correspond to the air cylinders through the delayer.

As shown in fig. 8, when the material is conveyed on the conveyor belt in a box, the conveyor belt adopts the roller shafts for conveying, the roller shafts are connected by the chains, and the conveyor belt can convey larger objects without deformation. In addition, a conveying limit rail 443 is arranged on the conveying belt, so that the boxes are positioned on a certain conveying track. Facilitating subsequent pushing. Conveying limit railing 443 is fixed on two sides of the conveyor belt through a fixing piece 441, the fixing piece 441 is fixedly connected with a rack of the conveyor belt, a screw rod 442 is arranged on the fixing piece 441 in a penetrating mode and screwed down through a nut 444, a connecting head 445 is arranged at one end of the screw rod 442, and a through hole for conveying limit railing 443 to pass through is formed in the connecting head 445.
