Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a top and bottom end of a bag on a belt conveyor in the front-back direction so that a snack confectionery packing bag in a three-sided sealed packing form can be easily packed in a cardboard box. The present invention relates to a method for raising a snack confectionery packaging bag, in which a snack confectionery packaging bag in a three-sided seal packaging form that is conveyed in a tilted state so as to face upright can be vertically raised to be aligned in a line. [0002] A snack confectionery packaging bag is generally packaged by a vertical bag-making filling and packaging machine, and is vertically sealed at the center of the back of the bag and horizontally sealed at the upper and lower ends of the bag. The snack confectionary is contained in the container and has a unique three-way seal packaging form in which the snack confectionery is inflated with air in order to avoid damage to the snack confectionery. Conventionally, the transportation of snack confectionery packaging bags is generally carried by a belt conveyor after being produced in a vertical bag-making filling and packaging machine, and the packaging of snack confectionery packaging bags has been often the case for snack confectionery. Due to the inability to grip the snack confectionery packaging bag to avoid damage and the unique configuration of the snack confectionery packaging bag, the snack confectionery packaging bags that are conveyed on the belt conveyor at a constant interval are picked up one by one by hand and then corrugated cardboard. Currently, it is packed in a box. So far, the method of mechanically packing snack confectionery packaging bags has been
It has been developed by several packaging machine manufacturers, but it uses an industrial robot to pick up one snack snack packaging bag with a vacuum hand and packs it into a cardboard box.
It is impossible to neatly arrange and pack them in a line, and the processing capacity cannot be increased compared to manual work,
Occasionally, snacks were damaged. Further, the method of mechanically packing the snack confectionery packaging bag that has been adopted by the applicant of the present invention is to drop several bags on a belt conveyor having a step and shift them little by little and then feed them sideways and drop them into a cardboard box, However, it was not possible to neatly line up and pack them in a line. Box packaging of snack confectionery packaging bags is like packaging air, unlike other commodities, and how to properly pack and increase the number of packaging remains a problem. SUMMARY OF THE INVENTION However, if the present inventors can raise the snack confectionery packaging bags which are conveyed on the belt conveyor at a certain pitch apart one after another and stick them together in a line, The idea is that the subsequent process, which is similar to the packaging of instant noodles in a cardboard box, can accommodate the snack confectionery packaging bags in a single row, which can be performed very easily by both manual work and mechanical processing. Proposed. The present invention has been devised in view of the above-mentioned points, and in order to easily pack a snack confectionery packaging bag in a three-sided sealed packaging form into a cardboard box, the upper and lower ends of the bag are separated by a certain pitch on the belt conveyor. An object of the present invention is to provide a method for raising a snack confectionery packaging bag, which can vertically stand up three-side sealed packaging type snack confectionery packaging packages that are conveyed in a state of being oriented in a vertical direction and can be aligned in a line. I am trying. According to the present invention, the conveyor surface is oscillated from the lower side of the conveyer 3 whose right and left sides are separated from each other through the central gap 3b toward the downstream side in the conveying direction and continuously moves in the conveying direction. Snack confectionery packaging bags H, H, ... which are conveyed onto the conveyor 3 by a plurality of bag raising claws 2a, 2a which sequentially repeat the operation of gradually sinking through the slits 4a provided in the adjacent table 4. .. are raised one after another and arranged in a line on the table 4 to provide a method for raising a snack confectionery packaging bag. 1 (a) and 1 (b) show a method for raising a snack confectionery packaging bag according to an embodiment of the present invention. In this method, the endless chain 1a of the chain winding device 1 is provided with bag raising claws 2a, 2a, ...
a central gap 3b from the lower side of the conveyor 3 having a and 3a
Through the slits 4a provided on the table 4 adjacent to the downstream side of the conveyor 3 in the standing state so as to gradually sink. The three-side-seal-packed snack confectionery packaging bag H, which has been conveyed to, is brought into contact with the bag-raising claw 2a that is standing on the downstream side, and is started up by the standing-up operation of the next bag-raising claw 2a, and is started up one after another. The snack confectionery packaging bags H, H, ... Are arranged in a line on the table 4. The details will be described below. The table 4 is provided on the downstream side of the conveyor 3 which constantly runs the endless belt 3a by the motor 3c, and the chain winding device 1 is arranged across the conveyor 3 and the lower side of the table 4, and the chain winding device is provided. One endless chain 1a is provided with two endless belts 3a so that the conveyor conveying surface is divided into left and right so that nine bag raising claws 2a, 2a, ... A gap 3b is formed between the belts 3a, 3a to allow the bag raising claw 2a to pass through, and a slit 4 is also formed in the center of the table 4 near the conveyor 3.
a is secured. The chain winding device 1 includes an endless chain 1a on three sprockets 1b, 1c, 1d.
, And the bag follower claws 2a, 2a, ... And the cam followers 2c, at both ends of each of the L-shaped links 2b, 2b ,. 2c, ... are attached, and the bag raising claw 2
In order to make a desired rocking and rising motion when a travels,
The cam followers 2c, 2c, ...
a, 5b to guide the sprocket 1b to the servomotor 1
It rotates at e and runs on the endless chain 1a. The distance between the pivot points of the L-shaped links 2b is such that when the pivot point of one L-shaped link 2b is located at the upper end of the sprocket 1c, the pivot point of the front L-shaped link 2b is located at the upper end of the sprocket 1d. The servomotor 1e stops driving when the pivot point of one L-shaped link 2b reaches the upper end of the sprocket 1d, and the snack confectionery packaging bag H is conveyed onto the conveyor 3. Driving is started, and at the time when the snack confectionery packaging bag H is conveyed onto the conveyor 3, a sensor (not shown) provided at an appropriate position in the upstream side of the conveyor 3 or the downstream side of the conveyor 3 Detected, the servo motor 1e starts driving by the detection signal of the sensor, and the rotation of the motor output shaft is rotated by a required angle by the built-in or external encoder. Detect and stops driving by counting the pulse. Then, when the pivotal point of one L-shaped link 2b comes to the upper end of the sprocket 1b, the bag raising claw 2a attached to the L-shaped link 2b causes the conveying surface to move between the gaps 3b in the center of the conveyor 3. When the snack confectionery packaging bag H is stopped and conveyed on the conveyor 3 at a height slightly lower than that of the snack confectionery packaging bag H, the servo motor 1e is intermittently driven to move the endless chain 1a,
When the pivot point of the L-shaped link 2b moves away from the sprocket 1b and moves toward the sprocket 1c, the bag raising claw 2a in the horizontal position is largely swung while moving toward the downstream in the conveying direction, and is a snack confectionery packaging bag. The snack confectionery packaging bag H is moved while standing upright, and the front end of the snack confectionery packaging bag H is brought into contact with the previous bag raising claw 2a standing up through the slit 4a formed in the table 4 as a slip stopper, and the snack confectionery packaging bag H is then packed. Make sure to rock the bag H upright,
When the pivot point of the rising L-shaped link 2b reaches the upper end of the sprocket 1c, the servo motor 1e is intermittently stopped and the bag raising claw 2a stands vertically to raise the bag raising claw one front side. The snack confectionery packaging bag H is sandwiched in an upright state in cooperation with 2a. That is, from the time when one snack confectionery packaging bag H is raised until the time when the next snack confectionery packaging bag H is raised, the one snack bag swing pawl 2a that swings and stands and the one downstream side thereof is still sinking. The snack confectionary packaging bag H that has been raised is sandwiched by the bag raising claw 2a that does not exist. Therefore, the snack confectionery packaging bag H has no fear of falling over. Then, the pivot point of the L-shaped link 2b reaches the upper end of the sprocket 1c, and the bag-raising claw 2a that is supported by the L-shaped link 2b and stands up.
When e is intermittently driven, it continues to stand vertically, moves in the transport direction, and largely sinks, and is separated from the snack confectionery packaging bags H, H. The slit 4a formed in the table 4 avoids interference with the bag rising claw 2a and ensures that the bag rising claw 2a is depressed. The bag raising claw 2a standing on the table 4 is
Since the bag raising claw 2a sinks, if the both ends of the horizontal seal portion at the upper end of the snack confectionary packaging bag H standing on the pair of left and right horizontal guide rails 6a and 6b are placed, the pair of left and right horizontal guide rails are placed. The snack snack packaging bags H, H, ... on the front side supported by 6a, 6b are pushed by one. Then, when the number of bags is lined up so as to be packed in the cardboard box at one time, the bag is moved forward by a separately provided horizontally moving pusher (not shown) to be separated from the bag which is started up later. The method for raising the snack confectionery packaging bag according to the present invention is not limited to the belt conveyor as the conveyor 3, but may be a roller table conveyor or other conveyors. Further, at least two bag raising claws 2a, 2a may be arranged so as to circulate the operation of oscillating upright toward the downstream in the transport direction and then gradually sinking. In this case, it is sufficient that the bag raising claw 2a oscillates and stands up within the gap 3b in the center of the conveyor 3 so that the bag raising claw 2a gradually sinks, and the table 4 is provided with a position where the bag raising claw 2a sinks. It is not necessary to perform it at the slit 4a. Therefore, the snack confectionery packaging bag H may be erected on the conveyor 3 and then transferred onto the table 4, and it is not necessary to erect the snack confectionery packaging bag H on the table 4. As described above, according to the method for raising the snack confectionery packaging bag of the present invention, the upper and lower ends of the bag are fixed on the belt conveyor so that the upper and lower ends of the bag are constantly inclined in the front-back direction. It is possible to vertically stand up the snack confectionery packaging bag in the form of a three-sided seal packaging that is conveyed at a pitch and can be surely aligned in a single-row close contact state.
