Description

  The present invention relates to a belt profile and a belt with a profile that are used by being attached to a toothed belt so as to hold and convey a conveyed object such as a steel plate, a can, or a bill by a magnetic force.

  In general, when carrying a belt by attracting and holding steel plates or cans by magnetic force, or holding and holding banknotes by magnetic force, a belt made of rubber mixed with a magnetic material or a magnet sheet is used as the carrying belt. Affixed belt is often used.

  However, a belt mixed with a magnetic material or a belt attached with a magnet sheet is liable to be hindered in its flexibility and may cause problems such as early cracking. On the other hand, if an attempt is made to increase the flexibility of the belt by reducing the amount of magnetic material mixed in, it is not possible to obtain a sufficient magnetic force required to hold the conveyed object.

  On the other hand, as in Patent Document 1, for example, a large number of profiles (magnet holding portions) 102 are fixed to the back surface of the belt 101 at intervals in the longitudinal direction of the belt 101 by welding and bolting. By holding the (magnet piece) 103, it is conceivable to impart sufficient magnetism to the belt without inhibiting the flexibility of the belt 101 (see FIG. 4).

JP 2000-289820 (paragraph numbers 0006, 0007, 0010, FIG. 1)

  However, since the belt of Patent Document 1 has a profile attached to the back surface of the belt by welding and bolting, the profile cannot be easily attached and detached, and a part of the profile is damaged. Even the whole belt needs to be replaced. In addition, it is necessary to form the profile with a material that can be welded to the back surface of the belt, and the selection of the material for the profile is likely to be restricted.

  An object of the present invention is to provide a belt profile and a belt with a profile that can impart sufficient magnetism to the belt and can be easily attached to and detached from the toothed belt.

  In order to achieve the above object, the belt profile according to the present invention is used by being attached to a toothed belt so as to hold and convey the object to be conveyed by magnetic force. A profile main body arranged on the back side of the belt, and a claw portion arranged on the tooth surface side of the toothed belt so as to be locked to the belt teeth while sandwiching a part of the toothed belt between the profile main body and A connecting portion formed integrally with the profile main body and the claw portion, and integrated with the toothed belt in the belt width direction so as to be attached to the toothed belt in the belt width direction. It is formed by dividing into a plurality of divided bodies.

  According to the above configuration, the profile body having magnetism is arranged on the back side of the toothed belt by attaching it to the toothed belt, so that sufficient magnetism is imparted to the belt without hindering the flexibility of the belt. can do. In addition, the profile is attached to the toothed belt by locking the claw part to the belt teeth and sandwiching a part of the toothed belt between the profile body, so welding or adhesion to the back of the belt is unnecessary It is possible to increase the degree of freedom of profile material selection.

  In addition, since the profile is formed by being divided into a plurality of divided bodies in the belt width direction, it can be easily attached to and detached from the toothed belt. Specifically, by inserting a part of the toothed belt between the profile body and the claw part and integrating the divided bodies so as to sandwich the toothed belt in the belt width direction, The profile can be attached, and vice versa, the profile can be removed from the toothed belt.

  In order to make the profile body have magnetism, the profile body may be made of a magnetic material, but magnets can be accommodated in the profile body to impart magnetism. According to this configuration, the degree of freedom in selecting the profile material can be increased, and the profile can be easily formed and handled.

  Moreover, the division surface which divides | segments a profile into a several division body can be set to the position which passes the magnet accommodating part which accommodates the magnet of a profile main body. According to this configuration, since the magnet accommodating portion is opened on the dividing surface, the magnet can be taken in and out when the profile is attached to and detached from the belt, and the magnet can be easily accommodated and replaced.

  Further, by providing the belt with a profile by providing the belt profile to the toothed belt, sufficient magnetism can be imparted without hindering the flexibility of the belt. In addition, the profile can be easily attached to the toothed belt and processed into a profiled belt because the profile can be easily attached and detached, and if some profiles are damaged, only the damaged profiles are replaced. It is only necessary to replace the entire belt.

  As described above, according to the present invention, by attaching a magnetic profile, it is possible to impart sufficient magnetism to the belt without hindering the flexibility of the belt, resulting in problems such as a crack in the belt. Therefore, it is possible to reliably hold and transport a transported object such as a steel plate, a can, or a banknote with a magnetic force. In addition, since the profile can be attached to the belt without welding or bonding, the degree of freedom in selecting the profile material can be increased.

  In addition, since it can be easily attached to and detached from the toothed belt, it is easy to process the toothed belt into a profiled belt, and if a part of the profile is damaged, the entire belt can be replaced. Without replacement, only damaged profiles can be replaced and repaired.

  Hereinafter, embodiments for carrying out a belt profile and a belt with profile according to the present invention will be described with reference to the drawings.

  The profile 1 has a desired number of teeth on the toothed belt 2 so as to hold and convey the object to be conveyed by magnetic force, such as holding and holding a steel plate or can by magnetic force, or sandwiching and holding a bill or the like magnetically. It is used by being mounted, and is divided into two divided bodies 1a and 1b at the center in the belt width direction.

  This profile 1 includes a profile main body 3 disposed on the back side of the toothed belt 2, a magnet 4 for imparting magnetism to the profile main body 3, and a side edge 2 a of the toothed belt 2 between the profile main body 3. A claw portion 6 that is held by the belt teeth 5 while being clamped, and a connecting portion that is formed integrally with the profile body 3 and the claw portion 6 so as to pass through the outside of the side surface of the toothed belt 2. 7.

  The toothed belt 2 has belt teeth 5 that mesh with the pulley teeth of the toothed pulley, and the belt width is set wider than the length in the central axis direction of the toothed pulley. Thereby, among the toothed belt 2 wound around the toothed pulley, the side edge portion 2a sandwiched between the profile body 3 and the claw portion 6 protrudes from the toothed pulley in the belt width direction, and the toothed belt 2 This prevents the claw portion 6 from obstructing the meshing with the toothed pulley.

  The profile main body 3 includes a magnet housing portion 3a for housing the magnet 4 and a main body base portion 3b integrally formed on the lower side of the magnet housing portion 3a so as to contact the back surface of the toothed belt 2. A split surface 8 that divides the profile main body 3 into split bodies 1a and 1b is formed at the center of the profile main body 3 in the belt width direction.

  The magnet housing portion 3a is a rectangular parallelepiped whose dimension in the belt width direction is set slightly smaller than the belt width of the toothed belt 2, and is formed in a cylindrical shape whose central axis is parallel to the belt width direction, for example. By accommodating the columnar magnet 4 in the accommodating space 9, magnetism is imparted to the profile body 3.

  The main body base portion 3b has a rod shape having a substantially square cross section in which both end portions protrude from both sides of the toothed belt 2 in the belt width direction and the size in the belt longitudinal direction is set smaller than that of the magnet housing portion 3a. This prevents the lowering of the flexibility of the toothed belt 2 due to the profile main body 3 coming into contact with the back surface of the belt while setting the upper surface of the profile main body 3 that attracts the object to be conveyed by a magnetic force.

  The dividing surface 8 is set at the center of the profile body 3 in the belt width direction so as to pass through the magnet housing portion 3a. When the profile body 3 is divided into divided bodies 1a and 1b, the housing space 9 is divided. To open. The dividing surface 8 is formed with a locking portion 8a and a locked portion 8b, and the divided portions 1a and 1b are integrated by locking the locking portion 8a to the locked portion 8b. It has become.

  The nail | claw part 6 is formed in the shape fitted in the tooth gap of the belt tooth | gear 5 of the toothed belt 2, and is arrange | positioned at the tooth surface side of the toothed belt 2, The side edge part 2a is the main body base part 3b of the profile main body 3. The belt is fitted into the tooth groove of the toothed belt 2 and is locked to the belt teeth 5 to prevent displacement in the belt longitudinal direction.

  The connecting portion 7 is a pair of rods whose width in the longitudinal direction of the belt is approximately the same as that of the main body base portion 3b and the claw portion 6, and is spaced from the lower surface of the main body base portion 3b with approximately the same interval as the belt width of the toothed belt 2. A claw portion 6 is formed so as to protrude to the tooth surface side and protrude inward in the belt width direction from the tip portion.

  In order to attach the profile 1 to the toothed belt 2, the main body base 3 b and the claw are inserted into each of the divided bodies 1 a and 1 b while inserting the magnet 4 into the housing space 9 of the magnet housing 3 a opened at the dividing surface 8. The claw portion 6 is fitted into the tooth groove of the belt tooth 5 so that the side edge portion 2 a of the toothed belt 2 is inserted between the belt teeth 5. Further, by sandwiching the toothed belt 2 in the belt width direction between the two divided bodies 1a and 1b, the locking portion 8a is locked to the locked portion 8b, and the divided bodies 1a and 1b are integrated, whereby the profile 1 is integrated. Is attached to the toothed belt 2. Further, the profile 1 can be detached from the toothed belt 2 in the reverse procedure.

  According to the above configuration, magnetism is imparted by attaching the profile 1 with the toothed belt 2 as it is, so that the toothed belt 2 can be wound around the pulley while leaving a gap between the adjacent profiles 1. As a result, the magnetism can be sufficiently increased without impairing the flexibility of the toothed belt 2, and the conveyed object can be securely held by magnetic force without causing problems such as cracks in the toothed belt 2. Can be transported. In addition, since the pulley diameter and the number of teeth can be freely set as long as the flexibility of the toothed belt 2 is not impaired, the degree of freedom in designing the layout of the belt and the pulley can be increased.

  Furthermore, the profile body 3 is composed of a magnet housing portion 3a and a body base portion 3b, and the size of the magnet housing portion 3a in the longitudinal direction of the belt is set to be large, and the size of the body base portion 3b in contact with the belt back surface is set to be small. The flexibility of the profiled belt can be further enhanced while freely setting the size and shape of the magnet 4.

  Further, since the profile 1 can be easily attached to and detached from the toothed belt 2, the toothed belt 2 can be easily processed into a profiled belt, and when some of the profiles 1 are damaged, Only the profile 1 can be replaced and repaired.

  Further, since the side edge 2a of the toothed belt 2 is sandwiched and attached, the material of the toothed belt 2 and the profile 1 can be freely selected. Accordingly, a standard component made of, for example, rubber or urethane can be used as the toothed belt 2 without being restricted by the material, and the profile 1 is made of a material suitable for direct contact with the transported portion. can do.
