[0029] As Figures 1-4 The embodiment provides an emergency bypass structure of a carton folding device of a carton unscrambler, and the emergency bypass structure can control the carton folding device of the carton unscrambler and is used for stacking empty cartons.
[0030] The bottom of the empty carton is provided with an opening, and the top is provided with a cover plate; when incoming, the cover plate is in a closed state.
[0031] The carton folding device of the carton unscrambler comprises a programmable logic controller 5, a carton folding machine, and a folding frame 6 connected with the programmable logic controller 5 through a control signal. The folding frame 6 has a separated state and a folded state, corresponding to the unfolded and stacked cartons respectively. When the cartons are fed, the folding frame 6 is in the unfolded state, and the cartons are set on the folding frame 6 in the vertical direction by a mechanical hand or other structure, and the cartons naturally fall under the action of gravity. Under normal circumstances, the cartons fall during the process, and the cover plate is pushed open by the folding frame 6, and finally the cartons fall to the preset position, and then the programmable logic controller 5 makes the folding frame 6 in the folded state, that is, the cartons are stacked.
[0032] The emergency bypass structure comprises a selection module 1 for manual operation, a separation operation module 2 and a folding operation module 3, and the signals of the selection module 1, the separation operation module 2 and the folding operation module 3 are all connected to the input module 4 of the programmable logic controller 5. The selection module 1 has an open and closed state. When the selection module 1 is in the open state, the separation operation module 2 is used to make the folding frame 6 in the separated state, and the folding operation module 3 is used to make the folding frame 6 in the folded state.
[0033] On the one hand, the mechanical hand can put the cartons on the folding frame 6, and the cartons naturally fall to the preset position under the action of gravity.
[0034] On the other hand, when the cartons do not fall into place, such as the hardness of the carton material is high, etc., the cover plate cannot be pushed open by the folding frame 6, resulting in that the cartons are suspended or inclined on the folding frame 6, and the programmable logic controller 5 cannot control the folding frame 6 to be in the folded state to make the cartons stacked. At this time, the emergency bypass structure is manually operated, that is, by manual method, first operate the selection module 1 to make it in the open state, and then alternately operate the separation operation module 2 and the folding operation module 3 one or more times, make the folding frame 6 in the separated state by the separation operation module 2, that is, the cartons are unfolded, and make the folding frame 6 in the folded state by the folding operation module 3, that is, the cartons are stacked, so that the cartons fall into place. The emergency bypass structure is connected with the programmable logic controller 5 through a control signal, and the operation of the emergency bypass structure can make the folding frame 6 in the folded state and the separated state through the programmable logic controller 5, and after multiple operations, the cartons can fall to the preset position.
[0035] The original equipment of the carton folding device of the unpacking machine can control the folding frame 6 to be in the closed state by the programmable logic controller 5, which is the prior art and will not be described again. The carton folding device of the unpacking machine also includes a detection member 8 in communication with the programmable logic controller 5. When the empty carton falls to the preset position and the cover is pushed open by the folding frame 6, the detection member 8 can detect the empty carton and feed back a signal, and then the programmable logic controller 5 makes the folding frame 6 be in the closed state. The empty carton automatically falls to the preset position and the empty carton is manually lowered to the preset position through the emergency bypass structure, both of which can be detected by the detection member 8 to realize the automatic switching of the emergency bypass structure to the original control system of the folding device. The selection module 1 is in the closed state after the empty carton falls to the preset position. The detection member 8 is a sensor, which can only detect the bottom of the empty carton when the empty carton falls to the preset position.
[0036] Therefore, after operating the emergency bypass structure, it can automatically recover to the automatic operation state and stop manual operation. The programmable logic controller 5 makes the folding frame 6 be in the closed state, realizes the stacking of the empty carton, and continues the subsequent work. By manually intervening in the emergency bypass structure outside the unpacking machine, the carton can be lowered to the position, avoiding direct pulling operation on the carton in the working range of the mechanical hand, reducing the safety risk and accident hidden danger; the carton folding function can be quickly realized, saving production time.
[0037] By setting the selection module 1, only when it is in the open state, the operation of the separating operation module 2 and the closing operation module 3 can act on the folding frame 6, and when the selection module 1 is in the closed state, the operation of the separating operation module 2 and the closing operation module 3 cannot act on the folding frame 6, preventing misoperation.
[0038] The folding frame 6 includes a frame body 62 and a driving member. The driving member drives the frame body 62 to make the frame body 62 be in the separated state and the closed state. The programmable logic controller 5, the separating operation module 2 and the closing operation module 3 are all in communication with the driving member. In one embodiment, the driving member is a pneumatic cylinder 61, and one of the separating operation module 2 and the closing operation module 3 is used to make the piston rod of the pneumatic cylinder 61 extend, and the other is used to make the piston rod of the pneumatic cylinder 61 reset. The frame body 62 is of a telescopic folding structure, for example, including four mutually hinged connecting rods. The first connecting rod is fixed, the piston rod of the pneumatic cylinder 61 is connected to the second connecting rod opposite to the first connecting rod, the piston rod is extended to make the first connecting rod and the second connecting rod away, i.e. the folding frame 6 is in the separated state, and the piston rod is retracted to make the first connecting rod and the second connecting rod close, i.e. the folding frame 6 is in the closed state, which is simple and reliable in structure. The folding frame 6 can refer to the existing structure and is not limited.
[0039] The selection module 1 is a selection switch, for example, the selection switch has a key, the key has two positions, one is an opening position, and the other is a closing position, when the key is screwed to the opening position, the selection switch is in an opening state, and when the key is screwed to the closing position, the selection switch is in a closing state. The selection switch is provided with corresponding opening and closing marks, which facilitates identification of the current working state.
[0040] The separation operation module 2 and the folding operation module 3 are both button switches, and the button switches are pressed to realize the action. The button switch of the separation operation module 2 has a first mark, and the button switch of the folding operation module 3 has a second mark, so as to realize the differentiation of the separation operation module 2 and the folding operation module 3 and prevent misoperation. For example, the differentiation is realized by color, one button switch is a red button, and the other button switch is a green button. For example, the differentiation is realized by labeling, the button switch of the separation operation module 2 is labeled with a label with the word “separation”, and the button switch of the folding operation module 3 is labeled with a label with the word “folding”.
[0041] The programmable logic controller 5 is, for example, a Siemens 300 series programmable logic controller.
[0042] For example, the folding frame 6 further comprises an electromagnetic valve 7, which is in communication connection with the programmable logic controller 5 to control the extension and retraction of the cylinder 61. The DC 24V signals of the selection switch and the two button switches are connected to the input module 4, and a bypass action control program is written, which can be referred to the prior art and will not be described here. When the button switch of the separation operation module 2 is pressed, the piston rod of the cylinder 61 extends, and when the button switch of the folding operation module 3 is pressed, the piston rod of the cylinder 61 resets.
[0043] The emergency bypass structure comprises a button box, and the selection module 1, the separation operation module 2 and the folding operation module 3 are all installed in the button box, that is, the selection switch and the two button switches in the embodiment are all integrated in the button box, which is convenient for operation and assembly. The outer part of the carton box folding device has a frame or a stand, and the button box is installed on the frame or the stand. The folding frame 6 is exposed to the outside, or the carton box folding device has an observation window, through which the folding frame 6 can be observed, and the state of the empty box and the folding frame 6 can be observed.
[0044] In other embodiments, the selection module 1, the separation operation module 2 and the folding operation module 3 can be keys on an operation screen, without limitation.
[0045] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and also impossible to exhaust all the implementation modes. Any modification, equivalent replacement and improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application claims.
