Abstract
Description
Technical Field
[0001] The present invention relates to the structure of a cutting machine, and particularly to a cutting machine with two rows arranged in a V shape.
Background Art
[0002] In the background art, in response to the need to cut materials in an elongated shape, manufacturers have designed an operation of conveying the elongated-shaped material by a conveyor belt and further cutting the elongated-shaped material using a rotating blade. When cutting a material that is relatively wide and elongated, the effective range cut by the blade is limited, and the cutting by the blade is arranged in only one row, resulting in limited production capacity.
[0003] Please refer to FIGS. 1A to 1D. FIGS. 1A to 1D respectively show an upper surface schematic view, a front plane schematic view, a supply mechanism schematic view, and a discharge mechanism schematic view of one type of cutting machine in the background art. This type of cutting machine includes a supply mechanism 1, a cutting body 2, and a discharge mechanism 3. This type of cutting machine sandwiches and conveys the raw material M1 with the sandwiching conveyor belts on both sides, performs an intermittent movement of a set length, passes through the position of the cutting trajectory of the blade C, and cuts the raw material M1 at a certain length. A supply conveyor belt B1 is included in the supply mechanism 1, and a discharge conveyor belt B3 is included in the discharge mechanism 3. FIG. 2 shows an arrangement schematic view between the cutting body 2 of the prior art cutting machine with two rows arranged in a V shape in FIG. 1A and related components.
[0004] When the raw material is a loose material, a supply-side sandwiching conveyor belt B21 and a discharge-side sandwiching conveyor belt B22 are respectively arranged on the supply side and the discharge side of the cutting body 2. The supply-side sandwiching conveyor belt B21 corresponds to the supply conveyor belt B1, and the discharge-side sandwiching conveyor belt B22 corresponds to the discharge conveyor belt B3. A gap G is provided at the connecting portion of the supply-side sandwiching conveyor belt B21 and the discharge-side sandwiching conveyor belt B22, and the cutting trajectory of the blade C during the cutting operation is passed through to cut the raw material M1.
[0005] When the width of the raw material M1 is relatively wide, the raw material M1 is installed horizontally, and the supply-side sandwiching conveyor belt B21 and the discharge-side sandwiching conveyor belt B22 sandwich and convey the raw material M1 horizontally and cut it with the cutting tool C. Immediately after the cutting tool C rotates and before it passes through the cross-section of the above-mentioned raw material M1 next, the raw material M1 is quickly sandwiched and conveyed at intervals of time until the cutting tool C rotates and passes through the cross-section of the raw material M1 described above, and then stops after a certain length. In this way, the operations of cutting and conveying are performed periodically. By the above operations, when cutting is performed periodically in a certain dimension and the entire length of the raw material M1 is cut, it further moves to another new raw material M1.
[0006] When the cutting tool C performs a cutting operation, its tip rotates along the tip locus U (as shown in Figure 2). The central axis part of the cutting tool C is coupled to the rotating part A, and the rotation center O of the rotating part A is positioned on the fixed holder S. The rotating part A can rotate around the rotation center O, thereby moving the tip of the cutting tool C along the tip locus U.
[0007] The motor E can move and rotate the cutting tool C by means of the belt L and the related belt pulleys. At the initial stage of cutting, since the tip locus U of the cutting tool C can reach the bottom of the cross-section of the raw material M1, the raw material M1 can be completely cut. When the cutting tool C wears and becomes smaller later, by operating the lever B, the fixed holder S can be rotated around the rotation center D, and the fixed holder S can be pulled down, and the rotation center O of the rotating part A can be lowered. Thereby, the cutting tool C is lowered in the direction of the raw material M1 so that the tip locus U of the cutting tool C can surely pass through the entire cross-section of the raw material M1, and the raw material M1 is cut.
[0008] In response to the need to cut raw materials in the form of elongated shapes stacked in a scattered manner, a supply conveyor belt B1 with a wide loading and transportation surface is arranged in the supply mechanism 1. By combining the guide protection plates H1 on both sides, the elongated raw material M1 is transported and fed into the cutting body 2. Further, the supply-side clamping and conveying belt B21 of the cutting body 2 gradually becomes smaller to clamp and convey the elongated raw material M1, and moves intermittently in synchronization with the discharge-side clamping and conveying belt B22. Using the time interval when the cutting tool C disengages from the cutting range, the material is conveyed in a fixed dimension. When the material is stationary and not being conveyed, the cutting tool C cuts the elongated raw material M1. After periodically performing cutting and conveying operations, the finished product M2 after cutting is discharged from the discharge mechanism 3. The discharge mechanism 3 is also provided with guide protection plates H2 on both sides to support the finished product M2 so that it does not become scattered.
[0009] Refer to FIG. 3. When the raw material in the form of an elongated shape to be cut is a relatively wide product and a structure for cutting in multiple rows is used to increase production capacity (for example, including two supply-side clamping and conveying belts B21a, B21b transporting two elongated raw materials M1a, M1b respectively), the tip trajectory U of the cutting tool C can no longer meet the cutting requirements. Although expanding the tip trajectory U to another tip trajectory U1 can cover the entire required operating range, if the rotation center O of the rotating part A is deviated far from the original rotation center in this way, the arrangement of the components of the entire cutting body 2 will become extremely difficult. To overcome this problem, in the background art, the movement of the cutting tool is changed to a pendulum-type movement mode, but this requires a relatively large installation space. Furthermore, the pendulum or the linear reciprocating transverse movement makes the installation of the entire mechanism more complex, increases the installation cost, and requires a larger space.
Summary of the Invention
Problems to be Solved by the Invention
[0010] Accordingly, the main object of the present invention is to provide a cutting machine with two rows arranged in a V shape, which can efficiently cut wide and elongated materials at low equipment costs and with a compact equipment layout space.
Means for Solving the Problems
[0011] To achieve the above object, the present invention includes a first supply-side sandwiching and conveying belt for supplying an elongated raw material supplied by a supply mechanism to a cutting body, a second supply-side sandwiching and conveying belt for supplying another elongated raw material supplied by the supply mechanism to the cutting body, a first discharge-side sandwiching and conveying belt corresponding to the first supply-side sandwiching and conveying belt via a gap, a second discharge-side sandwiching and conveying belt corresponding to the second supply-side sandwiching and conveying belt via a gap, and a cutting tool whose tip locus passes through the gap when rotating. Both the first supply-side sandwiching and conveying belt and the second supply-side sandwiching and conveying belt are arranged corresponding to each other at a V-shaped inclination angle in the cutting body. Correspondingly, the first discharge-side sandwiching and conveying belt and the second discharge-side sandwiching and conveying belt are also arranged corresponding to each other at a V-shaped inclination angle in the cutting body. The tip locus of the cutting tool passes through the entire cross-section of the elongated raw material and another elongated raw material without leaving any, cutting the elongated raw material and another elongated raw material to produce a plurality of finished products.
[0012] The central shaft portion of the cutting tool is coupled to a rotating part, and the rotation center of the rotating part is positioned by a fixed holder. The rotating part can rotate around the rotation center, thereby moving the tip of the cutting tool along the tip locus. The first supply-side sandwiching and conveying belt and the second supply-side sandwiching and conveying belt are arranged corresponding to each other at the V-shaped inclination angle in the cutting body with the rotation center of the rotating part as the center. The first discharge-side sandwiching and conveying belt and the second discharge-side sandwiching and conveying belt are also arranged corresponding to each other at the V-shaped inclination angle in the cutting body with the rotation center of the rotating part as the center.
[0013] The supply mechanism includes a first supply conveyor belt corresponding to the first supply-side sandwiching conveyor belt and a second supply conveyor belt corresponding to the second supply-side sandwiching conveyor belt.
[0014] Both the first supply conveyor belt and the second supply conveyor belt are arranged corresponding to each other at the V-shaped inclination angle in the supply mechanism.
[0015] The discharge mechanism includes a first discharge conveyor belt corresponding to the first discharge-side sandwiching conveyor belt and a second discharge conveyor belt corresponding to the second discharge-side sandwiching conveyor belt.
[0016] When the first discharge conveyor belt receives a plurality of the finished products from the first discharge-side sandwiching conveyor belt and further discharges the plurality of finished products, the angles at different conveying positions of the first discharge conveyor belt are asymptotic inclination angles that gradually become smaller. The asymptotic inclination angle has a horizontal working surface, and the first discharge conveyor belt and the second discharge conveyor belt finally discharge the plurality of finished products by the horizontal working surface respectively.
Advantages of the Invention
[0017] In terms of effects, the present invention does not need to significantly increase equipment and space. Within the rotation operation range of the cutting tool in the original equipment, two rows of conveyor belts arranged in a V-shape are arranged to sandwich an elongated raw material and cut it with a cutting tool. Furthermore, the angles at different conveying positions of the discharge conveyor belt in the present invention are asymptotic inclination angles that gradually become smaller respectively, and the conveyor belts finally discharge the plurality of finished products by the horizontal working surface respectively. Therefore, it is convenient for subsequent processing operations, does not require an additional control mechanism, and has the advantages of high-speed transportation and low cost.

DETAILED DESCRIPTION OF THE INVENTION
[0020] Please refer to Figs. 4A to 4D. Figs. 4A to 4D respectively show an upper surface schematic view, a front plane schematic view, a supply mechanism schematic view, and a discharge mechanism schematic view of a cutting machine with two rows arranged in a V shape according to the present invention. Fig. 5 shows a schematic view of the arrangement between the cutting body 2a and related components in Fig. 4A. The cutting machine of the present invention includes two rows of supply mechanisms 1a and 1b. In the first supply mechanism 1a, a first supply conveyor belt B1a and combined side guide protection plates H1a are included. In the second supply mechanism 1b, a second supply conveyor belt B1b and combined side guide protection plates H1b are included.
[0021] The cutting machine of the present invention includes two rows of discharge mechanisms 3a and 3b. In the first discharge mechanism 3a, a first discharge conveyor belt B3a and combined side guide protection plates H3a are included. In the second discharge mechanism 3b, a second discharge conveyor belt B3b and combined side guide protection plates H3b are included.
[0022] In the cutting body 2a, two rows of supply-side clamping conveyor belts B21a and B21b are included. The first supply-side clamping conveyor belt B21a corresponds to the first supply conveyor belt B1a, and further, side guide protection plates H21a are provided on both sides. The second supply-side clamping conveyor belt B21b corresponds to the second supply conveyor belt B1b, and further, side guide protection plates H21b are provided on both sides.
[0023] In the cutting body 2a, two rows of discharge-side clamping conveyor belts B22a and B22b are included. The first discharge-side clamping conveyor belt B22a corresponds to the first discharge conveyor belt B3a, and further, side guide protection plates H22a are provided on both sides. The second discharge-side clamping conveyor belt B22b corresponds to the second discharge conveyor belt B3b, and further, side guide protection plates H22b are provided on both sides.
[0024] The first supply conveyor belt B1a is combined with the side guide protection plates H1a to transport the raw material M1a in an elongated shape and enter it into the first supply-side clamping conveyor belt B21a in the cutting body 2a. When the raw material M1a in an elongated shape is cut by the blade C of the cutting body 2a, a plurality of finished products M2a are produced, pass through the first discharge-side clamping conveyor belt B22a and the first discharge conveyor belt B3a in sequence, and are discharged from the first discharge mechanism 3a.
[0025] The second supply conveyor belt B1b is combined with the both-side guide protection plates H1b to transport another elongated raw material M1b and let it enter the second supply-side clamping and conveying belt B21b in the cutting body 2a. When another elongated raw material M1b is cut by the blade C of the cutting body 2a, a plurality of finished products M2b are produced, which pass through the second discharge-side clamping and conveying belt B22b and the second discharge conveyor belt B3b in sequence and are discharged from the second discharge mechanism 3b.
[0026] FIG. 5 shows a schematic layout diagram among the cutting body 2a and related components in the cutting machine with two rows of the present invention arranged in a V shape in FIG. 4A.
[0027] When the blade C performs a cutting operation, its tip rotates along the tip locus U. The central shaft part of the blade C is coupled to the rotating part A, and the rotation center O of the rotating part A is positioned by the fixed holder S. The rotating part A can rotate around the rotation center O, thereby moving the tip of the blade C along the tip locus U.
[0028] The motor E can move and rotate the blade C by means of the belt L and related belt pulleys. If necessary, the operator can operate the lever B to rotate the fixed holder S around the rotation center D and lower the fixed holder S, thereby lowering the rotation center O of the rotating part A. Thereby, the blade C is lowered in the direction of the elongated raw materials M1a, M1b, so that the tip locus U of the blade C can surely pass through the entire cross section of the elongated raw materials M1a, M1b, and the elongated raw materials M1a, M1b are cut.
[0029] In the present invention, the first supply-side clamping and conveying belt B21a and the second supply-side clamping and conveying belt B21b are centered on the rotation center O of the rotating part A and are arranged corresponding to each other at a V-shaped inclination angle θ in the cutting body 2a. That is, when the blade C cuts the elongated raw materials M1a, M1b, the elongated raw materials M1a, M1b present corresponding inclined working surfaces and are respectively located on the first supply-side clamping and conveying belt B21a and the second supply-side clamping and conveying belt B21b.
[0030] Correspondingly, the first discharge-side sandwiching conveyor belt B22a and the second discharge-side sandwiching conveyor belt B22b also rotate around the rotation center O of the rotating part A and are arranged corresponding to each other with a V-shaped inclination angle θ in the cutting body 2a. In this way, without changing the arrangement of the cutting tool and related mechanisms in the background art, it is possible to increase the production output and production capacity of the equipment.
[0031] To correspond to the first supply-side sandwiching conveyor belt B21a and the second supply-side sandwiching conveyor belt B21b arranged corresponding to each other with a V-shaped inclination angle θ, the first supply conveyor belt B1a and the second supply conveyor belt B1b are also arranged with a V-shaped inclination angle (as shown in FIG. 4C).
[0032] In terms of the discharge mechanisms 3a and 3b, after the elongated raw materials M1a and M1b are cut, subsequent processes (such as packaging) are supplied together and discharged continuously at intervals. Therefore, the present invention corresponds to the first discharge-side sandwiching conveyor belt B22a and the second discharge-side sandwiching conveyor belt B22b installed at the aforementioned V-shaped inclination angle, and specially designs the first discharge conveyor belt B3a and the second discharge conveyor belt B3b with a structure that gradually inclines in the opposite direction.
[0033] Please refer to FIG. 6. In the arrangement of the first discharge conveyor belt B3a and the second discharge conveyor belt B3b of the present invention, a conveyor belt structure with a curved shape is designed to convert the inclined working surface of the conveyor belt into a horizontal working surface. Taking the example that the first discharge conveyor belt B3a transports a plurality of finished products, when the first discharge conveyor belt B3a receives the finished product M2a from the first discharge-side sandwiching conveyor belt B22a and further discharges the finished product M2a, the angles at different transport positions P1 to P5 of the first discharge conveyor belt B3a are respectively asymptotic inclination angles θ1 to θ5 that gradually become smaller, and among them, the asymptotic inclination angle θ5 has a horizontal working surface. In this way, since the first discharge conveyor belt B3a and the second discharge conveyor belt B3b can each discharge the respective finished products M2a by means of a horizontal working surface, subsequent processing operations are convenient, no additional control mechanism is required, and it has the advantages of high-speed transportation and low cost.
[0034] The above embodiments merely exemplarily explain the structural design of the present invention and do not limit the present invention. Any person skilled in the art can modify and change the above-described embodiments under the structural design and spirit of the present invention, but these changes still fall within the spirit of the present invention and the patent scope defined below. Therefore, the scope of the protection of the rights of the present invention should be included in the scope of the claims for utility model registration described below.
