Description

  The present invention relates to a cartoning machine that packs and seals a product such as a tablet in a carton.

  As this kind of cartoning machine, a so-called intermittent cartoning machine is known that intermittently conveys products and cartons and performs packaging by operating a filling device and a sealing device whose conveyance direction is fixed while the conveyance is stopped. (See, for example, Patent Document 1).

  FIG. 4 shows the concept of the intermittent carting machine. According to this, the product supply unit 101 that supplies a certain amount of product (packed with tablets, etc.) 100 is transferred to a plurality (two in the illustrated example) and transferred intermittently to the product transport unit 102. The In the product transport unit 102, the attached document 104 supplied from the attached document supply unit 103 is wound around the product 100, and a QR code check or the like is performed.

  On the other hand, a carton 107 that has been subjected to a QR code check or the like and subjected to a seal inspection at the carton supply unit 106 is supplied to one carton in an unsealed state by detecting the conveyance of the product 100. Be transported.

  While the conveyance of the product 100 and the carton 107 is stopped, the product 100 of the product conveyance unit 102 is filled in the carton 107 of the carton conveyance unit 105 in the filling unit 108, and the carton 107 is sealed in the sealing unit 109. (Glued) At this time, since the product 100 is supplied from the product supply unit 101 to 60 units / minute, the filling unit 108 performs the filling operation at 30 reciprocations / minute and the sealing unit 109 performs the sealing operation at 30 cycles / minute. In the carton transport unit 105 after the sealing unit 109, defective product discharge → weight check → defective product discharge is appropriately performed.

However, in the conventional intermittent cartoning machine as described above, under the condition that a certain amount of product is supplied, when combining a small carton with a large number of processing boxes and a large carton with a small number of processing boxes,
(1) In the case of a small carton, the product / carton transport speed increases, so the behavior of the product becomes severe and the stability is lacking.
(2) When a small carton is used, the filling speed of the product into the carton is high, and the force applied to the product by the filling pusher or the like is increased to damage the product.
There is a problem.

  That is, in the conventional intermittent cartoning machine, the stability is lowered when a large carton-compatible machine is also used as a small carton compared to a small carton dedicated machine.

  Accordingly, an object of the present invention is to provide a highly stable carting machine having both intermittent and continuous functions.

  In order to achieve such an object, a cartoning machine according to the present invention includes a product transfer unit capable of switching between continuous and intermittent transfer of products, and a continuous carton in which the products are filled in parallel with the product transfer unit. An XY axis of a filling pusher which is provided at least one side of the carton transport unit capable of intermittent transport switching and fills the carton of the carton transport unit with the product of the product transport unit It is provided on both sides of the carton transport unit, which can be switched between operation and Y-axis operation, and can be reciprocated and fixed in the transport direction to seal the carton after filling the product. It is characterized by comprising: a sealing part; and a control means for performing a series of operations by synchronously controlling driving means for independently driving the product conveying part, the carton conveying part, the filling part and the sealing part.

  Further, the control means switches between an intermittent operation and a continuous operation according to the type of the carton. During the intermittent operation, the product conveying unit and the carton conveying unit are intermittently conveyed, the sealing unit is fixed, and the filling is performed. The Y-axis operation of the filling pusher is controlled by controlling the driving of the unit, and during the continuous operation, the product conveying unit and the carton conveying unit are continuously conveyed and the sealing unit is reciprocated, and the filling unit It is characterized in that the XY axis movement of the filling pusher is made possible by controlling the driving of the filling pusher.

  Further, the control means switches to an intermittent operation in the case of a large carton having a low conveyance and filling speed, and switches to a continuous operation in the case of a small carton having a high conveyance and filling speed.

  According to the cartoning machine according to the present invention, switching between continuous / intermittent conveyance of the product conveyance unit and the carton conveyance unit, limitation of the filling unit to be driven, and switching between the XY axis operation and the Y axis operation of the filling pusher, Since the reciprocating operation / fixed switching in the transport direction of the sealing portion is performed, an intermittent type or a continuous type function can be selected as necessary, thereby increasing versatility.

  Moreover, versatility is further enhanced by switching between intermittent operation and continuous operation according to the type of carton. In addition, it is possible to suppress the conveyance speed and filling speed of products and cartons by switching to intermittent operation for large cartons with low conveyance and filling speeds and switching to continuous operation for small cartons with high conveyance and filling speeds. , Stability and product safety are increased.

  DESCRIPTION OF EMBODIMENTS Hereinafter, a cartoning machine according to the present invention will be described in detail with reference to the drawings by way of examples.

  FIG. 1 is a schematic configuration diagram of a cartoning machine showing an embodiment of the present invention, FIG. 2 is an explanatory diagram of an action during an intermittent operation, and FIG. 3 is an explanatory diagram of an action during a continuous operation.

  As shown in FIG. 1, the present cartoning machine has a carton 3 filled with the product 1 by a driving means (not shown) in a product transporting section 2 capable of switching between continuous and intermittent transport of the product 1 by a driving means (not shown). A carton transport unit 4 capable of switching between continuous and intermittent transport is provided in parallel. That is, the conveyance direction lines of the product conveyance unit 2 and the carton conveyance unit 4 are adjacent to each other in parallel.

  Two filling pushers (filling parts) 5a and 5b (two stations) are provided on one side of the product conveying part 2 (on the opposite side of the carton conveying part 4), and the product of the product conveying part 2 is driven by a driving means (not shown). It is possible to switch between an XY-axis operation (see arrow A in the figure) and a Y-axis operation (see arrow B in the figure) of a filling operation unit (not shown) that fills the carton 3 of the carton conveying unit 4 with 1 It has become.

  On both sides of the carton transport unit 4, sealing units 6a and 6b that can be reciprocated in the transport direction and fixed and switched in order to seal the carton 3 after product filling by a driving means (not shown) are provided.

  The drive means of the product conveying section 2, carton conveying section 4, filling pushers (filling sections) 5a, 5b and sealing section 6 are synchronously controlled by a control device (control means) such as a microcomputer (not shown). Thus, the carting machine performs a series of operations. Specifically, the control device switches between intermittent operation and continuous operation according to the size (type) of the carton 3.

  That is, in the case of a large carton 3a having a small number of processing (filling) boxes and having a slow conveyance and filling speed, an intermittent operation is performed. As shown in FIG. 2, the product conveyance unit 2 and the carton conveyance unit 4 are intermittently operated. The sealing pushers 6a and 6b are fixed and the filling pusher 5b is driven in the Y-axis direction (see arrow B in the figure), and the filling pusher 5a is fixed or removed. At this time, the filling pusher 5b and the sealing portions 6a and 6b perform a series of operations when the conveyance is stopped.

  As a result, the function of the intermittent carting machine is performed as before, and stable conveyance and the safety of the product 1 are ensured.

  On the other hand, in the case of a small carton 3b having a large number of processing (filling) boxes and having a high conveying and filling speed, it is continuously operated. During the continuous operation, as shown in FIG. 3, the product conveying unit 2 and the carton conveying unit 4 are continuously connected. The seals 6a and 6b are reciprocated in the transport direction while being transported, and are driven in the XY axis direction (arrow A in the figure) with the two filling pushers 5a and 5b. At this time, the filling pushers 5a and 5b and the sealing portions 6a and 6b perform a series of operations while moving according to the conveyance speed.

  Thereby, the function of a continuous carting machine is simulated, and the conveyance speed of the product 1 and the carton 3b can be suppressed, so that stable conveyance can be performed. Further, since two filling pushers 5a and 5b are used and the filling speed can be suppressed, damage to the product 1 can be reduced.

  In this way, in this embodiment, an intermittent type or continuous type function can be selected as necessary, so that a highly versatile cartoning machine can be provided. In addition, since the difference in conveying speed between the small carton 3b and the large carton 3a is small, there is an advantage that the hot melt (glue) application amount can be easily adjusted.

  Needless to say, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention. For example, at least two filling pushers 5a and 5b are sufficient.

It is a schematic block diagram of the carting machine which shows one Example of this invention. It is an operation explanatory view similarly at the time of intermittent operation. It is an operation explanatory view at the same time of continuous operation. It is a schematic structure perspective view of the conventional intermittent cartoning machine.
