DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
The technical contents and the expected effectiveness of the present invention will become more apparent from the detailed description of the preferred embodiment in conjunction with the accompanying drawings.
Figures 1 to 4 are perspective and top schematic views respectively showing a vertical type vacuum packing machine of the present invention. As shown in these figures, the vertical type vacuum packing machine essentially conducts film-bag delivering, material feeding, evacuation and film-bag sealing procedures in vertically conveying mode so as to achieve vacuum packing. The vertical type vacuum packing machine of the present invention essentially comprises:
a material incoming device (1) which is an inlet hopper (11) provided at the upper side of the frame-base (10);
a weighing device (2) oppositely disposed at the upper side of the inlet hopper (11), which is a mechanism, for example, a flow rate detector, a timer or a scale, to weigh the object to be packed each time;
a film-bag delivering device (3) which is a film-bag roller (31), having a packing film-bag (30) wrapped on it, provided on the frame-base (10), the film-bag roller (31) introducing a packing film-bag (30) to the inlet hopper (11) for accommodating the weighed object to be packed;
a vacuum packing device (4) oppositely disposed at the lower side of the material incoming device (1) for receiving the packing film-bag (30) already filled with object to be packed, vacuum packing device (4) being provided with a case body (41) having a left half (41a) and a right half (4 lb) capable of closing with each other, an evacuation device and a to vibratory mechanism (40) being provide within the case body (41) which is also provided with a blade set (42) having a primary cutting section (421) for producing a bag-opening of the packing film-bag (30) and a secondary cutting section (422) for the severing of the packing film-bag (30), a first sealing blade (43) for sealing the bottom of the subsequent packing film-bag (30) and a second sealing blade (44) for sealing the bag-opening of the precedent packing film-bag (30) being provided at the upper and lower ends of the blade set (42) respectively.
Figures 2 to 13 are schematic views showing the actions of the vertical type vacuum packing machine of the present invention. As shown in these figures, when the machine is operated, the object to be packed is filled in the weighing device (2) and the weight of each pack is measured by the flow rate detecting meter, the timer or the scale etc.
based on the weight of each pack set by the weighing device (2), then the weighed object to be packed is dropped into the material incoming device (1) in which the inlet hopper (11) is inserted with a packing film-bag (30) unwounded from the film-bag roller (31) of the film-bag delivering device (3). In some cases, the material incoming device (1) on the frame-base (10) can also installed more than one inlet hopper (11), so the film-bag delivering device (3) has to introduce corresponding numbers of packing film-bags (30) with respect to the quantity of the inlet hopper (11). In turn, the weighed object to be packed is dropped into the inlet hopper (11) first and then filled into the packing film-bag (30) with bottom sealed (in the initial usage, the bottom of said packing film-bag (30) is sealed at first). Then, the packing film-bag (30) filled with object is dropped in the vacuum packing device (4). A sensor (411) for sensing the entry of a packing film-bag into the case body (41) is provided on the case body (41) of the vacuum packing device (4).
When sensor (411) receives a sensing signal, the left and the right halves (41a), (41b) of the case body (41) conduct primary mould-closing causing the blade set (42) within the case body (41) to present an extending state of the first section. At this moment, the primary cutting section (421) of the blade set (42) is used to produce a bag-opening on the surface of the packing film-bag (30) for air-exhaust. Subsequently, the packing film-bag loaded with object to be packed is abutted with the vibratory mechanism (40) which has a disk body (401) for abutment with the packing film-bag loaded with object to be packed. The disk body (401) is driven by a power source (402) to generate vibration and to conduct air-exhaust. At the same time, further cooperating with the evacuation action under complete mould-closing state, the air within the packing film-bag (30) is exhausted to the ambience through the bag-opening. Simultaneously, the first and the second sealing blade (43), (44) at the upper and lower ends of the blade set (42) conduct the bottom-sealing for the subsequent packing film-bag (30) and the opening-sealing for the precedent packing film-bag (30) respectively.
At the completion of the bottom-sealing and opening-sealing actions, the blade set (42) also extends its secondary cutting section (422) out to conduct severing action between the sealed opening of the preceding packing film-bag (30) and the sealed bottom of the subsequent packing film-bag (30) so that the vacuum packing of the preceding packing film-bag (30) and the bottom-sealing of the subsequent packing film-bag (30) are thus finished. Finally, the vacuum packing device (4) conduct mould-opening to cause the stripping of the product. Repeated operation in this manner, vacuum packing operation in mass production can be achieved by the vertical type vacuum packing machine.
Figure 14 is a schematic view showing the state of another implementation of the blade set of the vertical type vacuum packing machine of the present invention. As shown in the figure, aside from the design of aforementioned two sections type of producing a bag-opening and severing, the blade set (42) can be designed to have a primary cutter (423) directed for producing the bag-opening of the packing film-bag (30) (can also be a needle type primary blade which makes bag-opening in dot or segment pattern) and a secondary cutter (424) directed for the severing of the packing film-bag (30), which are 5 formed as a pair. In this manner, the bag-opening producing and the severing actions can be conducted on the packing film-bag (30) by a double-cutter set.
The abovementioned embodiments and drawings are not used to limit of the scope of the present invention. Equivalent variations and 10 modifications made by the person skilled in the art without departing from the spirit and scope of the present invention are still considered to be within the scope of the present invention.
Based on the foregoing, the vertical type vacuum packing machine of the present invention has the following advantages when comparing with the conventional structure.

Figures 2 to 13 are schematic views showing the actions of the vertical type vacuum packing machine of the present invention. As shown in these figures, when the machine is operated, the object to be packed is filled in the weighing device (2) and the weight of each pack is measured by the flow rate detecting meter, the timer or the scale etc.
based on the weight of each pack set by the weighing device (2), then the weighed object to be packed is dropped into the material incoming device (1) in which the inlet hopper (11) is inserted with a packing film-bag (30) unwounded from the film-bag roller (31) of the film-bag delivering device (3). In some cases, the material incoming device (1) on the frame-base (10) can also installed more than one inlet hopper (11), so the film-bag delivering device (3) has to introduce corresponding numbers of packing film-bags (30) with respect to the quantity of the inlet hopper (11). In turn, the weighed object to be packed is dropped into the inlet hopper (11) first and then filled into the packing film-bag (30) with bottom sealed (in the initial usage, the bottom of said packing film-bag (30) is sealed at first). Then, the packing film-bag (30) filled with object is dropped in the vacuum packing device (4). A sensor (411) for sensing the entry of a packing film-bag into the case body (41) is provided on the case body (41) of the vacuum packing device (4).
When sensor (411) receives a sensing signal, the left and the right halves (41a), (41b) of the case body (41) conduct primary mould-closing causing the blade set (42) within the case body (41) to present an extending state of the first section. At this moment, the primary cutting section (421) of the blade set (42) is used to produce a bag-opening on the surface of the packing film-bag (30) for air-exhaust. Subsequently, the packing film-bag loaded with object to be packed is abutted with the vibratory mechanism (40) which has a disk body (401) for abutment with the packing film-bag loaded with object to be packed. The disk body (401) is driven by a power source (402) to generate vibration and to conduct air-exhaust. At the same time, further cooperating with the evacuation action under complete mould-closing state, the air within the packing film-bag (30) is exhausted to the ambience through the bag-opening. Simultaneously, the first and the second sealing blade (43), (44) at the upper and lower ends of the blade set (42) conduct the bottom-sealing for the subsequent packing film-bag (30) and the opening-sealing for the precedent packing film-bag (30) respectively.
At the completion of the bottom-sealing and opening-sealing actions, the blade set (42) also extends its secondary cutting section (422) out to conduct severing action between the sealed opening of the preceding packing film-bag (30) and the sealed bottom of the subsequent packing film-bag (30) so that the vacuum packing of the preceding packing film-bag (30) and the bottom-sealing of the subsequent packing film-bag (30) are thus finished. Finally, the vacuum packing device (4) conduct mould-opening to cause the stripping of the product. Repeated operation in this manner, vacuum packing operation in mass production can be achieved by the vertical type vacuum packing machine.
Figure 14 is a schematic view showing the state of another implementation of the blade set of the vertical type vacuum packing machine of the present invention. As shown in the figure, aside from the design of aforementioned two sections type of producing a bag-opening and severing, the blade set (42) can be designed to have a primary cutter (423) directed for producing the bag-opening of the packing film-bag (30) (can also be a needle type primary blade which makes bag-opening in dot or segment pattern) and a secondary cutter (424) directed for the severing of the packing film-bag (30), which are 5 formed as a pair. In this manner, the bag-opening producing and the severing actions can be conducted on the packing film-bag (30) by a double-cutter set.
